Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation Our accompanying Consolidated Financial Statements and these Notes to Consolidated Financial Statements include subsidiaries in which we have a controlling financial interest. We own and operate FNBPA, FNTC, First National Investment Services Company, LLC, FNBIA, FNIA, Bank Capital Services, LLC, F.N.B. Capital Corporation, LLC and Waubank Securities, LLC, and include results for each of these entities in the accompanying Consolidated Financial Statements. Companies in which we hold a controlling financial interest, or are a VIE, in which we have the power to direct the activities of an entity that most significantly impact the entity’s economic performance and have an obligation to absorb losses or the right to receive benefits which could potentially be significant to the VIE, are consolidated. For a voting interest entity, a controlling financial interest is generally where we hold more than 50% of the outstanding voting shares. VIEs in which we do not hold the power to direct the activities of the entity that most significantly impact the entity’s economic performance or an obligation to absorb losses or the right to receive benefits which could potentially be significant to the VIE are not consolidated. Investments in companies that are not consolidated are accounted for using the equity method when we have the ability to exert significant influence or the cost method when we do not have the ability to exert significant influence. Investments in private investment partnerships that are accounted for under the equity method or the cost method are included in other assets and our proportional interest in the equity investments’ earnings are included in other non-interest income. Investment interests accounted for under the cost and equity methods are periodically evaluated for impairment. The accompanying Consolidated Financial Statements include all adjustments that are necessary, in the opinion of management, to fairly reflect our financial position and results of operations in accordance with GAAP. All significant intercompany balances and transactions have been eliminated. Certain prior period amounts have been reclassified to the current period presentation. Such reclassifications had no impact on our net income and stockholders' equity. Events occurring subsequent to December 31, 2023 have been evaluated for potential recognition or disclosure in the Consolidated Financial Statements through the date of the filing of the Consolidated Financial Statements with the SEC. Use of Estimates Our accounting and reporting policies conform with GAAP. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements. Actual results could materially differ from those estimates. Material estimates that are particularly susceptible to significant changes include the ACL, fair value of financial instruments, goodwill and other intangible assets and income taxes and DTAs. Adoption of New Accounting Standards Reference Rate Reform. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848), as amended, which provides optional guidance for a limited period of time to ease the potential burden in accounting for changes in financial reporting brought about by RRR for affected contractual modifications of floating rate financial instruments indexed to interbank offering rates and hedge accounting relationships. The expedients, exceptions and elections provided by RRR are permitted to be adopted any time through December 31, 2024 and do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2024, except for certain optional expedients elected for certain hedging relationships existing as of December 31, 2024. In general, RRR provides, when certain criteria are met, optional expedients and exceptions regarding the accounting for contract modifications, hedging relationships and other transactions affected by RRR. It also allows for a one-time transfer or sale of qualifying HTM securities. We adopted RRR on October 1, 2020, and the guidance will be followed until the Update terminates on December 31, 2024. The adoption did not have a material impact on our consolidated financial position or results of operations. Loans Effective January 1, 2023, we adopted the provisions of ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which eliminated the accounting for troubled debt restructurings (TDRs) while expanding loan modification and vintage disclosure requirements. The ASU has been applied prospectively. The adoption did not result in a material impact to our Consolidated Financial Statements. Under ASU 2022-02, the corporation is required to apply the loan refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan. Modifications granted to borrowers experiencing financial difficulty may be in the form of an interest rate reduction, an other-than-insignificant payment delay, a term extension, principal forgiveness or a combination thereof (collectively referred to as Troubled Debt Modifications or TDMs). Modifications that do not impact the contractual payment terms, such as covenant waivers, and insignificant payment deferrals are not included in the disclosures. The Corporation uses various indicators to identify borrowers in financial difficulty. Consumer loan borrowers that are delinquent and commercial loan borrowers that are rated substandard or worse are the primary criteria used to identify borrowers who are experiencing financial difficulty. The presentation of our loan modification disclosures has been updated to reflect information on loan modifications given to borrowers experiencing financial difficulty and can be found within Note 6, Loans and Leases. Additionally, our vintage disclosures have been updated to reflect gross charge-offs by year of origination. Prior to the adoption of ASU 2022-02, the Corporation accounted for certain loan modifications and restructurings as TDRs. In general, a modification or restructuring of a loan constituted a TDR if the Corporation granted a concession to a borrower experiencing financial difficulty. Business Combinations Business combinations are accounted for by applying the acquisition method. Under the acquisition method, identifiable assets acquired and liabilities assumed, and any non-controlling interest in the acquiree at the acquisition date are measured at their fair values as of that date, and are recognized separately from goodwill. Results of operations of the acquired entities are included in the Consolidated Statements of Income from the date of acquisition. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, cash items in transit and amounts due from the FRB and other depository institutions (including interest-bearing deposits). Debt Securities Debt securities can be classified as trading, HTM or AFS securities. As of December 31, 2023 and 2022, we did not hold any trading debt securities. Interest income on debt securities includes amortization of purchase premiums or accretion of discounts. Premiums and discounts on debt securities are generally amortized on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable debt securities are amortized to their earliest call date. A debt security is placed on non-accrual when principal or interest becomes greater than 90 days delinquent. Interest accrued but not received for a security placed on non-accrual is reversed against interest income. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. HTM debt securities are securities that management has the positive intent and ability to hold until their maturity. Such securities are carried at amortized cost. For certain HTM securities we have an expectation of zero expected credit losses. Based on a long history with no credit losses, high credit ratings, guarantees, and/or implied risk-free characteristics, we expect the non-payment risk associated with our UST, Fannie Mae, Freddie Mac, FHLB, Ginnie Mae and SBA securities to be zero, and accordingly, have no ACL on those securities. We believe that these qualitative factors are indicators that historical credit loss information should be nominally impacted, if at all, by current conditions and R&S forecasts. As such, we believe that without a change in these indicators, we may continue to assume zero credit losses on securities concluded to exhibit those factors. We also have a portfolio of HTM debt securities where we do not expect credit losses to be zero. This portfolio consists of high-grade municipal securities. To calculate the expected credit losses on these securities we group securities by major security type, rating and maturity and apply respective cumulative default rates from a third-party data provider. The baseline credit loss estimate is adjusted using a qualitative approach to account for potential variability in probabilities of default data for current conditions and R&S forecasts. Where available, expected credit losses take into consideration any enhancement a security has such as insurance, a guarantee or state aid. Debt securities that are not classified as trading or HTM are classified as AFS and are carried at fair value. AFS debt securities in unrealized loss positions are evaluated for impairment related to credit losses at least quarterly. Impairment may result from credit deterioration of the issuer or collateral underlying the security. In performing an assessment of whether any decline in fair value is due to a credit loss, all relevant information is considered at the individual security level. For AFS debt securities in an unrealized loss position, we first determine whether we have the intent 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 the criteria for intent or requirement to sell is met, the security’s amortized cost is written down to fair value and the write down is charged against the ACL with any incremental impairment reported in earnings in the Provision for Credit Losses line on the Consolidated Statements of Income. For AFS debt securities that do not meet the criteria for intent or requirement to sell, we evaluate whether the decline in fair value has resulted from credit losses or other factors. We first qualitatively evaluate each security to assess whether a potential credit loss exists. If as a result of this qualitative analysis we expect to get all of our principal back, then we conclude that the present value of expected cash flows equals or exceeds its amortized cost and no credit loss exists. If it was determined that a potential credit loss exists, we compare the present value of cash flows expected to be collected with our amortized cost basis. The credit loss is recorded through the ACL and limited to the amount the fair value is less than the amortized cost basis. We have made an accounting policy election for each major security type of AFS debt securities to adjust the effective interest rate used to discount expected cash flows to consider the timing of expected cash flows resulting from expected prepayments. Impairment for noncredit-related factors is recorded in OCI, net of income taxes. Changes in the ACL are recorded as a provision for credit loss expense. Losses are charged against the ACL when an AFS debt security is not collectible or when we believe the criteria regarding the intent or requirement to sell is met. Securities Sold Under Agreements to Repurchase Securities sold under agreements to repurchase are accounted for as collateralized financing transactions and are recorded at the amounts at which the securities were sold plus accrued interest. Securities, generally U.S. government and federal agency securities, pledged as collateral under these financing arrangements cannot be sold or repledged by the secured party. The fair value of collateral either received from or provided to a third party is continually monitored and additional collateral is obtained or is requested to be returned to us as deemed appropriate. Derivative Instruments and Hedging Activities From time to time, we may enter into derivative transactions principally to protect against the risk of adverse price or interest rate movements on the value of certain assets and liabilities and on future cash flows. Foreign exchange derivatives are entered into to accommodate the needs of customers. All derivative instruments are carried at fair value on the Consolidated Balance Sheets as either an asset or liability. Accounting for the changes in fair value of a derivative is dependent upon whether it has been designated in a formal, qualifying hedging relationship. For derivatives in qualifying hedging relationships, we formally document all relationships between hedging instruments and hedged items, as well as our risk management objective and strategy for undertaking each hedge transaction. Cash flows from hedging activities are classified in the same category as the items hedged. Changes in fair value of a derivative instrument that has been designated and qualifies as a cash flow hedge, including any ineffectiveness, are recorded in AOCI, net of tax. Amounts are reclassified from AOCI to the Consolidated Statements of Income in the same line item used to present the earnings effect of the hedged item in the period or periods in which the hedged transaction affects earnings. At the hedge’s inception, a formal assessment is performed to determine whether changes in the fair values or cash flows of the derivative instruments have been highly effective in offsetting changes in fair values or cash flows of the hedged items and whether they are expected to be highly effective in the future. At each reporting period thereafter, a statistical regression or qualitative analysis is performed to evaluate hedge effectiveness. If it is determined a derivative instrument has not been or will not continue to be highly effective as a hedge, hedge accounting is discontinued. We also enter into interest rate swap agreements to meet the interest rate risk management needs of qualifying commercial loan customers. These agreements provide the customer the ability to convert from variable to fixed interest rates. We then enter into positions with a derivative counterparty in order to offset our exposure on the fixed components of the customer agreements. The credit risk associated with derivatives executed with customers is essentially the same as that involved in extending loans and is subject to normal credit policies and monitoring. We seek to minimize counterparty credit risk by entering into transactions with only high-quality institutions and using collateral agreements and other contract provisions. These arrangements meet the definition of derivatives, but are not designated as qualifying hedging relationships. The interest rate swap agreement with the loan customer and with the counterparty are reported at fair value in other assets and other liabilities on the Consolidated Balance Sheets with any changes in fair value recognized in current period earnings. Loans Held for Sale and Loan Commitments Certain of our residential mortgage loans are originated or purchased for sale in the secondary mortgage loan market. We make an automatic election to account for all originated or purchased residential mortgage loans held for sale under the FVO. The FVO election is intended to better reflect the underlying economics and better facilitate the economic hedging of the loans. The FVO is applied on an instrument-by-instrument basis and is an irrevocable election. Additionally, with the election of the FVO, fees and costs associated with the origination and acquisition of residential mortgage loans held for sale are expensed as incurred, rather than deferred. Changes in fair value under the FVO are recorded in mortgage banking operations non-interest income on the Consolidated Statements of Income. Fair value is determined on the basis of rates obtained in the respective secondary market for the type of loan held for sale. Gain or loss on the sale of loans is recorded in mortgage banking operations non-interest income. Interest income on loans held for sale is recorded in interest income. We routinely issue IRLCs for residential mortgage loans that we intend to sell. These IRLCs are considered derivatives. We also enter into loan sale commitments to sell these loans when funded to mitigate the risk that the market value of residential mortgage loans may decline between the time the rate commitment is issued to the customer and the time we sell the loan. These loan sale commitments are also derivatives. Both types of derivatives are recorded at fair value on the Consolidated Balance Sheets with changes in fair value recorded in mortgage banking operations non-interest income. We also originate loans guaranteed by the SBA for the purchase of businesses, business startups, business expansion, equipment and working capital. All SBA loans are underwritten and documented as prescribed by the SBA. SBA loans originated with the intention to sell on the secondary market are classified as held for sale and carried at the lower of cost or fair value. At the time of the sale, we allocate the carrying value of the entire loan between the guaranteed portion sold and the unguaranteed portion retained based on their relative fair value which results in a discount recorded on the retained portion of the loan. The guaranteed portion is typically sold at a premium and the gain is recognized in other income for any net premium received in excess of the relative fair value of the portion of the loan transferred. The net carrying value of the retained portion of the loans is included in the appropriate commercial loan classification for disclosure purposes. Loans Loans we intend to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, net of the ACL. Amortized cost primarily consists of the principal balances outstanding, deferred origination fees or costs and premiums or discounts on purchased loans. Interest income on loans is computed over the term of the loans using the effective interest method. Loan origination fees or costs, premiums or discounts are deferred and amortized over the term of the loan or loan commitment period as an adjustment to the related loan yield. Non-performing Loans We place loans on non-accrual status and discontinue interest accruals on loans generally when principal or interest is due and has remained unpaid for a certain number of days, unless the loan is both well secured and in the process of collection. Commercial loans and leases are placed on non-accrual at 90 days, installment loans are placed on non-accrual at 120 days and residential mortgages and consumer lines of credit are generally placed on non-accrual at 180 days, though we may place a loan on non-accrual prior to these past due thresholds as warranted. When a loan is placed on non-accrual status, all unpaid accrued interest is reversed against interest income and the amortization of deferred fees and costs is suspended. Non-accrual loans may not be restored to accrual status until all delinquent principal and interest have been paid and the ultimate ability to collect the remaining principal and interest is reasonably assured. Loans are charged-off against the ACL and recoveries of amounts previously charged-off are credited to the ACL when realized. Allowance for Credit Losses on Loans and Leases We estimate the ACL on loans and leases using relevant available information, from internal and external sources, relating to past events, current conditions, and R&S forecasts under the CECL methodology. The ACL is measured on a collective (pool) basis when similar risk characteristics exist. Our portfolio segmentation is characterized by similarities in initial measurement, risk attributes, and the manner in which we monitor and assess credit risk and is comprised of commercial real estate, commercial and industrial, commercial leases, commercial other, direct installment, residential mortgages, indirect installment and consumer lines of credit. The ACL on loans and leases represents our current estimate of lifetime credit losses in our loan portfolio at the balance sheet date. In determining the ACL, we estimate expected future losses for the loan's entire contractual term adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications. The ACL is the sum of three components: quantitative (formulaic or pooled) reserves; asset specific / individual loan reserves; and qualitative (judgmental) reserves. Quantitative Component We use a non-discounted cash flow factor-based approach to estimate expected credit losses that include component probability of default (PD)/LGD/exposure at default (EAD) models as well as less complex estimation methods for smaller loan portfolios. •PD: This component model is used to estimate the likelihood that a borrower will cease making payments as agreed. The major contributors to this are the borrower credit attributes and macro-economic trends. •LGD: This component model is used to estimate the loss on a loan once a loan is in default. •EAD: Estimates the loan balance at the time the borrower stops making payments. For all term loans, an amortization based formulaic approach is used for account level EAD estimates. We calculate EAD using a portfolio specific method in each of our revolving product portfolios. Asset Specific / Individual Component Loans that do not share risk characteristics are generally evaluated on an individual basis. Loans evaluated individually are not included in the collective evaluation. We have elected to apply the practical expedient to measure expected credit losses of a collateral dependent asset using the fair value of the collateral, less any costs to sell. Individual reserves are determined as follows: •For commercial loans in default which are greater than or equal to $1.0 million, individual reserves are determined based on an analysis of the present value of the loan's expected future cash flows, the loan's observable market value, or the fair value of the collateral less costs to sell. •For commercial and consumer loans in default which are below $1.0 million, an established LGD percentage is multiplied by the loan balance and the results are aggregated for purposes of measuring specific reserve impairment. Qualitative Component The ACL also includes identified qualitative factors related to distinctive risk factors, changes in current economic conditions that may not be reflected in quantitatively derived results, and other relevant factors to ensure the ACL reflects our best estimate of CECL. While our reserve methodologies strive to reflect all relevant risk factors, there continues to be uncertainty associated with, but not limited to, potential imprecision in the estimation process due to the inherent time lag of obtaining information and normal variations between estimates and actual outcomes. We may adjust reserves to reflect such risks. The ACL also includes factors that may not be directly measured in the determination of individual or collective reserves. Such qualitative factors may include: •Lending policies and procedures, including changes in policies and underwriting standards and practices for collections, write-offs, and recoveries; •The experience, ability, and depth of lending, investment, collection, and other relevant personnel; •The quality of the institution’s credit review function; •Concentrations of credit or changes in the level of such concentration; •The effect of other external factors such as the regulatory, legal and technological environments; competition; and events such as natural disasters and other relevant factors; and •Forecast uncertainty and imprecision. Liability for Credit Losses on Unfunded Lending-Related Commitments The AULC is management's estimate of credit losses inherent in our unfunded loan commitments, such as commercial and industrial revolving loan facilities, commercial real estate construction projects and home equity lines of credit, and is included in other liabilities on the Consolidated Balance Sheets. The AULC is estimated over the contractual period in which we are exposed to credit risk for obligations which are not unconditionally cancellable by us. The AULC is adjusted through provision for credit losses. 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 useful life. Consistent with our estimation process on our loan and lease portfolio, we use a non-discounted cash flow factor-based approach to estimate expected credit losses that include component PD/LGD/EAD models as well as less complex estimation methods for smaller portfolios. Purchased Credit Deteriorated Loans and Leases We have purchased loans and leases, some of which have experienced more than insignificant credit deterioration since origination and have established criteria to assess whether a purchased financial asset, or group of assets, should be accounted for as PCD on the acquisition date. The selection of which criteria to apply, or the addition of new criteria, to a specific acquisition will be based on the facts and circumstances at the time of review, as well as the availability of information supplied by the acquiree. Generally, more-than-insignificant deterioration in credit quality since origination would include risk ratings of special mention or below, inconsistency of loan payments, non-accrual status at the time of acquisition, or loans modified in a TDM, in bankruptcy or for regulatory purposes. PCD loans are recorded at the amount paid. The initial ACL is determined using the same methodology as other loans held for investment on a collective basis and is allocated to individual loans. The sum of the loan’s purchase price and the ACL becomes the 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 or accreted into interest income over the life of the loan. Subsequent changes to the ACL are recorded through the provision for credit losses. Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the asset’s estimated useful life. Leasehold improvements are expensed over the lesser of the asset’s estimated useful life or the term of the lease including renewal periods when reasonably assured. Useful lives are dependent upon the nature and condition of the asset and range from 3 to 39 years. Maintenance and repairs are charged to expense as incurred, while major improvements are capitalized and amortized to expense over the identified useful life. Premises and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Cloud Computing Arrangements We evaluate fees paid for cloud computing arrangements to determine if those arrangements include the purchase of or license to use software that should be accounted for separately as internal-use software. If a contract includes the purchase or license to use software that should be accounted for separately as internal-use software, the contract is amortized over the software’s identified useful life in amortization of intangibles. For contracts that do not include a software license, the contract is accounted for as a service contract with fees paid recorded in other non-interest expense. Other Real Estate Owned OREO is comprised principally of commercial and residential real estate properties obtained in partial or total satisfaction of loan obligations. OREO acquired in settlement of indebtedness is included in other assets initially at fair value of the asset less estimated selling costs. Subsequent to acquisition, OREO is accounted for at the lower of amortized cost or fair value less estimated selling costs. Changes to the value subsequent to transfer are recorded in non-interest expense along with direct operating expenses. Gains or losses not previously recognized resulting from sales of OREO are recognized in non-interest income on the date of sale. Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. Intangible assets that have finite lives, such as core deposit intangibles, customer relationship intangibles and renewal lists, are amortized over their estimated useful lives and subject to periodic impairment testing. Core deposit intangibles are primarily amortized over ten years using accelerated methods. Customer renewal lists are amortized over their estimated useful lives which range from eight to thirteen years. Goodwill and other intangibles are subject to impairment testing at the reporting unit level, which must be conducted at least annually. We perform impairment testing during the fourth quarter of each year, or more frequently if impairment indicators exist. We also continue to monitor other intangibles for impairment and to evaluate carrying amounts, as necessary. Quarterly, we perform a goodwill impairment assessment. We first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. Qualitative factors include, among other things, macroeconomic conditions, industry and market considerations, financial performance of the respective reporting unit and other relevant entity- and reporting-unit specific considerations. If we conclude it is more likely than not that the fair value of a reporting unit is less than its carrying value, a quantitative assessment is performed. If the quantitative assessment results in the fair value of the reporting unit exceeding its carrying value, goodwill of the reporting unit is considered not impaired; however, if the carrying value of the reporting unit exceeds its fair value, an impairment charge is recorded for the excess, limited to the amount of goodwill assigned to a reporting unit. Determining the fair value of a reporting unit under the goodwill impairment test is judgmental and often involves the use of significant estimates and assumptions. Similarly, estimates and assumptions are used in determining the fair value of other intangible assets. Estimates of fair value are primarily determined using discounted cash flows, market comparisons and recent transactions. These approaches use significant estimates and assumptions including projected future cash flows, discount rates reflecting the market rate of return, projected growth rates and determination and evaluation of appropriate market comparables. Loan Servicing Rights We have two primary classes of servicing rights, residential mortgage loan servicing and SBA-guaranteed loan servicing. We recognize the right to service residential mortgage loans and SBA-guaranteed loans for others as an asset whether we purchase the servicing rights or as a result from a sale of loans that we originated or purchased when the servicing is contractually separated from the underlying loan and retained by us. We initially record servicing rights at fair value in other assets on the Consolidated Balance Sheets. Subsequently, servicing rights are measured at the lower of cost or fair value. Servicing rights are amortized in proportion to, and over the period of, estimated net servicing income in mortgage banking operations non-interest income for residential mortgage loans and other non-interest income for SBA-guaranteed loans. The amount and timing of estimated future net cash flows are updated based on actual results and updated projections. MSRs are separated into pools based on common risk characteristics of the underlying loans and evaluated for impairment at least quarterly. SBA-guaranteed servicing rights are evaluated for impairment at least quarterly on an aggregate basis. Impairment, if any, is recognized when carrying value exceeds the fair value as determined by calculating the present value of expected net future cash flows. If impairment exists at the pool level for residential mortgage loans or on an aggregate basis for SBA-guaranteed loans, the servicing right is written down through a valuation allowance and is charged against mortgage banking operations non-interest income or other non-interest income, respectively. Bank Owned Life Insurance We have purchased life insurance policies on certain current and former directors, officers and employees for which the Corporation is the owner and beneficiary. These policies are recorded in the Consolidated Balance Sheets at their cash surrender value, or the amount that could be realized by surrendering the policies. Tax-exempt income from death benefits and changes in the net cash surrender value are recorded in BOLI non-interest income. Low Income Housing Tax Credit Partnerships We invest in various affordable housing projects that qualify for LIHTCs. The net investments are recorded in other assets on the Consolidated Balance Sheets. These investments generate a return through the realization of federal tax credits. We use the proportional amortization method to account for a majority of our investments in these entities. LIHTCs that do not meet the requirements of the proportional amortization method are recognized using the equity method. Leases We determine if an arrangement is, or contains, a lease at inception of the contract. As a lessee, we consider a contract to be, or contain, a lease if the contract conveys the right to control the use of an identified asset in exchange for consideration. We recognize in our Consolidated Balance Sheets the obligation to make lease payments and a right-of-use asset representing our right to use the underlying asset for the lease term. For an operating lease, the right-of-use asset and lease liability are included in other assets and other liabilities, respectively. Finance leases are included in premises and equipment, and other liabilities. We do not record leases with an initial term of 12 months or less on the Consolidated Balance Sheets, instead we recognize lease expense for these leases on a straight-line basis over the lease term. Right-of-use assets and liabilities are initially measured at the present value of lease payments over the lease term, discounted using the interest rate implicit in the lease at the commencement date. Right-of-use assets are adjusted for any lease payments made prior to lease commencement, lease incentives, and accrued rent. If the rate implicit in the lease cannot be readily determined, we discount the lease using our incremental borrowing rate which is derived by reference to FNB's secured borrowing rate. Our leases may include options to extend or terminate the lease. When it is reasonably certain that we will exercise such an option, the lease term includes those periods. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Lease expense for finance leases is recognized using the effective interest method. Certain of our lease agreements include variable rental payments based on a percentage of transactions and others include variable rental payments that periodically adjust to rates and charges stated in the agreements. Variable costs, such as maintenance expenses, property taxes, property insurance, transaction-based lease payments and index-based rate increases, are expensed as incurred. Right-of-use assets are reviewed for impairment when events or circumstances indicate that the carrying amount may not be recoverable. For operating leases, if deemed impaired, the right-of-use asset is written down and the remaining balance is subsequently amortized on a straight-line basis. We have real estate lease agreements with lease and non-lease components, which are generally accounted for as a single lease component. As a lessor, when a lease meets certain criteria indicating that we effectively have transferred control of the underlying asset to the customer, the lease is classified as a sales-type lease. When a lease does not meet the criteria for a sales-type lease but meets the criteria of a direct financing lease, the lease is classified as a direct financing lease. When none of the required criteria for sales-type lease or direct-financing lease are met, the lease is classified as an operating lease. Both sales-type leases and direct financing leases are recognized as a net investment in the lease on the Consolidated Balance Sheets. The net investment comprises the lease receivable including any residual value of the underlying asset that is guaranteed by the customer or any other third party unrelated to us and the unguaranteed residual value of the underlying asset. Operating lease income is recognized over the lease term on a straight-line basis. We do not evaluate whether sales taxes and similar taxes imposed by a governmental authority on lease transactions and collected by us are our primary obligation as owner of the underlying leased asset and exclude from lease income all taxes collected. Revenue from Contracts with Customers We earn certain revenues from contracts with customers. These revenues are recognized when control of the promised services is transferred to the customers in an amount that reflects the consideration we expect to be entitled to in an exchange for those services. In determining the appropriate revenue recognition for our contracts with customers, we consider whether the contract has commercial substance and is approved by both parties with identifiable contractual rights, payment terms, and the collectability of consideration is probable. Generally, we satisfy our performance obligations upon the completion of services at the amount to which we have the right to invoice or charge under contracts with an original expected duration of one year or less. We apply this guidance on a portfolio basis to contracts with similar characteristics and for which we believe the results would not differ materially from applying this guidance to individual contracts. Our services provided under contracts with customers are transferred at the point in time when the services are rendered. Generally, we do not defer incremental direct costs to obtain contracts with customers that would be amortized in one year or less under the practical expedient. These costs are recognized as expense, primarily salary and benefit expense, in the period incurred. Deposit Services. We recognize revenue on deposit services based on published fees for services provided. Demand and savings deposit customers have the right to cancel their depository arrangements and withdraw their deposited funds at any time without prior notice. When services involve deposited funds that can be retrieved by customers without penalties, we consider the service contract term to be day-to-day, where each day represents the renewal of the contract. The contract does not extend beyond the services performed and revenue is recognized at the end of the contract term (daily) as the performance obligation is satisfied. No deposit services fees exist for long-term deposit products beyond early withdrawal penalties, which are earned on these products at the time of early termination. Revenues from deposit services fees are reduced where we have a history of waived or reduced fees by customer request or due to a customer service issue, by historical experience, or another acceptable method in the same period as the related revenues. Revenues from deposit services are reported in the Consolidated Statements of Income as service charges and in the Community Banking segment as non-interest income. Wealth Management Services. Wealth advisory and trust services are provided on a month-to-month basis and invoiced as services are rendered. Fees are based on a fixed amount, or a scale based on the level of services provided or assets under management. The customer has the right to terminate their services agreement at any time. We determine the value of services performed based on the fee schedule in effect at the time the services are performed. Revenues from wealth advisory and trust services are reported in the Consolidated Statements of Income as trust services and securities commissions and fees, and in the Wealth segment as non-interest income. Insurance Services. Insurance services include full-service insurance brokerage services offering numerous lines of commercial and personal insurance through major carriers to businesses and individuals within our geographic markets. We recognize revenue on insurance contracts in effect based on contractually specified commission payments on premiums that are paid by the customer to the insurance carrier. Contracts are cancellable at any time, and we have no performance obligation to the customers beyond the time the insurance is placed into effect. Revenues from insurance services are reported in the Consolidated Statements of Income as insurance commissions and fees, and in the Insurance segment in the Business Segments footnote as non-interest income. Other Services. Other services primarily consist of fees generated from various ancillary revenue streams including capital markets revenue and miscellaneous consumer fees. A large portion of capital markets revenue consists of swap fee income, and this income is recognized during the period of swap execution. Revenues from other services are recognized when, or as, the performance obligation is satisfied and are reported in the Consolidated Statements of Income as non-interest income. Income Taxes We file a consolidated federal income tax return. The provision for federal and state income taxes is based on income reported on the Consolidated Financial Statements, rather than the amounts reported on the respective income tax returns. DTAs and DTLs are computed using tax rates expected to apply to taxable income in the years in which those assets and liabilities are expected to be realized. The effect on DTAs and DTLs resulting from a change in tax rates is recognized as income or expense in the period that the change in tax rates is enacted. We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments are applied in the calculation of certain tax credits and in the calculation of the deferred income tax expense or benefit associated with certain DTAs and DTLs. Significant changes to these estimates may result in an increase or decrease to our tax provision in a subsequent period. We recognize interest and/or penalties related to income tax matters in income tax expense. We assess the likelihood that we will be able to recover our DTAs. If recovery is not likely, we will increase our valuation allowance against the DTAs that are unlikely to be recovered by recording a provision for income taxes. We believe that we will ultimately recover the DTAs recorded on our Consolidated Balance Sheets. We periodically review the tax positions we take on our tax return and apply a more likely than not recognition threshold for all tax positions that are uncertain. The amount recognized in the Consolidated Financial Statements is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the more likely than not test, no tax benefit is recorded. Marketing Costs Marketing costs are generally expensed as incurred. Per Share Amounts Earnings per common share is computed using net income available to common stockholders, which is net income adjusted for preferred stock dividends. Basic earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding, net of unvested shares of restricted stock. Diluted earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding, adjusted for the dilutive effect of potential common shares issuable for stock options and restricted shares, as calculated using the treasury stock method. Adjustments to net income available to common stockholders and the weighted average number of shares of common stock outstanding are made only when such adjustments dilute earnings per common share. The assumed proceeds from applying the treasury stock method when computing diluted earnings per share excludes the amount of excess tax benefits that would have been recognized in accumulated paid-in capital. Retirement Plans We sponsor retirement plans for our employees. The calculation of the obligations and related expenses under these plans requires use of actuarial valuation methods and assumptions. The plans utilize assumptions and methods including reflecting trust assets at their fair value for the qualified pension plans and recognizing the overfunded and underfunded status of the plans on our Consolidated Balance Sheets. Gains and losses, prior service costs and credits are recognized in AOCI, net of tax, until they are amortized, or immediately upon curtailment. Stock-Based Compensation Our stock-based compensation awards require the measurement and recognition of compensation expense, based on estimated fair values, for all stock-based awards, including stock options and restricted stock units, made to employees and stock awards made to directors. Generally, these restricted stock unit awards to employees vest over a three-year service period and the stock awards made to non-employee directors vest over a one-year period. We are required to estimate the fair value of stock-based awards on the date of grant. For time-based awards, the value of the award is recognized as expense in our Consolidated Statements of Income over the shorter of requisite service periods or the period through the date that the employee first becomes eligible to retire. We granted restricted stock unit awards with multiple conditions, both performance and market conditions. These awards are accounted for by considering the market condition in the grant date fair value and recognizing compensation expense over the service period based on the grant date fair value and the probability that the performance condition will be met. We account for forfeitures as they occur.

Our accompanying Consolidated Financial Statements and these Notes to Consolidated Financial Statements include subsidiaries in which we have a controlling financial interest. We own and operate FNBPA, FNTC, First National Investment Services Company, LLC, FNBIA, FNIA, Bank Capital Services, LLC, F.N.B. Capital Corporation, LLC and Waubank Securities, LLC, and include results for each of these entities in the accompanying Consolidated Financial Statements.

Companies in which we hold a controlling financial interest, or are a VIE, in which we have the power to direct the activities of an entity that most significantly impact the entity’s economic performance and have an obligation to absorb losses or the right to receive benefits which could potentially be significant to the VIE, are consolidated. For a voting interest entity, a controlling financial interest is generally where we hold more than 50% of the outstanding voting shares. VIEs in which we do not hold the power to direct the activities of the entity that most significantly impact the entity’s economic performance or an obligation to absorb losses or the right to receive benefits which could potentially be significant to the VIE are not consolidated. Investments in companies that are not consolidated are accounted for using the equity method when we have the ability to exert significant influence or the cost method when we do not have the ability to exert significant influence. Investments in private investment partnerships that are accounted for under the equity method or the cost method are included in other assets and our proportional interest in the equity investments’ earnings are included in other non-interest income. Investment interests accounted for under the cost and equity methods are periodically evaluated for impairment.

The accompanying Consolidated Financial Statements include all adjustments that are necessary, in the opinion of management, to fairly reflect our financial position and results of operations in accordance with GAAP. All significant intercompany balances and transactions have been eliminated. Certain prior period amounts have been reclassified to the current period presentation. Such reclassifications had no impact on our net income and stockholders' equity. Events occurring subsequent to December 31, 2023 have been evaluated for potential recognition or disclosure in the Consolidated Financial Statements through the date of the filing of the Consolidated Financial Statements with the SEC.

Our accounting and reporting policies conform with GAAP. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements. Actual results could materially differ from those estimates. Material estimates that are particularly susceptible to significant changes include the ACL, fair value of financial instruments, goodwill and other intangible assets and income taxes and DTAs.

Reference Rate Reform. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848), as amended, which provides optional guidance for a limited period of time to ease the potential burden in accounting for changes in financial reporting brought about by RRR for affected contractual modifications of floating rate financial instruments indexed to interbank offering rates and hedge accounting relationships.

The expedients, exceptions and elections provided by RRR are permitted to be adopted any time through December 31, 2024 and do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2024, except for certain optional expedients elected for certain hedging relationships existing as of December 31, 2024.

Loans Effective January 1, 2023, we adopted the provisions of ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which eliminated the accounting for troubled debt restructurings (TDRs) while expanding loan modification and vintage disclosure requirements. The ASU has been applied prospectively. The adoption did not result in a material impact to our Consolidated Financial Statements.

Under ASU 2022-02, the corporation is required to apply the loan refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan. Modifications granted to borrowers experiencing financial difficulty may be in the form of an interest rate reduction, an other-than-insignificant payment delay, a term extension, principal forgiveness or a combination thereof (collectively referred to as Troubled Debt Modifications or TDMs). Modifications that do not impact the contractual payment terms, such as covenant waivers, and insignificant payment deferrals are not included in the disclosures. The Corporation uses various indicators to identify borrowers in financial difficulty. Consumer loan borrowers that are delinquent and commercial loan borrowers that are rated substandard or worse are the primary criteria used to identify borrowers who are experiencing financial difficulty.

Business combinations are accounted for by applying the acquisition method. Under the acquisition method, identifiable assets acquired and liabilities assumed, and any non-controlling interest in the acquiree at the acquisition date are measured at their fair values as of that date, and are recognized separately from goodwill. Results of operations of the acquired entities are included in the Consolidated Statements of Income from the date of acquisition.

Debt securities can be classified as trading, HTM or AFS securities. As of December 31, 2023 and 2022, we did not hold any trading debt securities. Interest income on debt securities includes amortization of purchase premiums or accretion of discounts. Premiums and discounts on debt securities are generally amortized on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable debt securities are amortized to

their earliest call date. A debt security is placed on non-accrual when principal or interest becomes greater than 90 days delinquent. Interest accrued but not received for a security placed on non-accrual is reversed against interest income. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.

HTM debt securities are securities that management has the positive intent and ability to hold until their maturity. Such securities are carried at amortized cost. For certain HTM securities we have an expectation of zero expected credit losses. Based on a long history with no credit losses, high credit ratings, guarantees, and/or implied risk-free characteristics, we expect the non-payment risk associated with our UST, Fannie Mae, Freddie Mac, FHLB, Ginnie Mae and SBA securities to be zero, and accordingly, have no ACL on those securities. We believe that these qualitative factors are indicators that historical credit loss information should be nominally impacted, if at all, by current conditions and R&S forecasts. As such, we believe that without a change in these indicators, we may continue to assume zero credit losses on securities concluded to exhibit those factors. We also have a portfolio of HTM debt securities where we do not expect credit losses to be zero. This portfolio consists of high-grade municipal securities. To calculate the expected credit losses on these securities we group securities by major security type, rating and maturity and apply respective cumulative default rates from a third-party data provider. The baseline credit loss estimate is adjusted using a qualitative approach to account for potential variability in probabilities of default data for current conditions and R&S forecasts. Where available, expected credit losses take into consideration any enhancement a security has such as insurance, a guarantee or state aid.

Debt securities that are not classified as trading or HTM are classified as AFS and are carried at fair value. AFS debt securities in unrealized loss positions are evaluated for impairment related to credit losses at least quarterly. Impairment may result from credit deterioration of the issuer or collateral underlying the security. In performing an assessment of whether any decline in fair value is due to a credit loss, all relevant information is considered at the individual security level.

For AFS debt securities in an unrealized loss position, we first determine whether we have the intent 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 the criteria for intent or requirement to sell is met, the security’s amortized cost is written down to fair value and the write down is charged against the ACL with any incremental impairment reported in earnings in the Provision for Credit Losses line on the Consolidated Statements of Income. For AFS debt securities that do not meet the criteria for intent or requirement to sell, we evaluate whether the decline in fair value has resulted from credit losses or other factors. We first qualitatively evaluate each security to assess whether a potential credit loss exists. If as a result of this qualitative analysis we expect to get all of our principal back, then we conclude that the present value of expected cash flows equals or exceeds its amortized cost and no credit loss exists. If it was determined that a potential credit loss exists, we compare the present value of cash flows expected to be collected with our amortized cost basis. The credit loss is recorded through the ACL and limited to the amount the fair value is less than the amortized cost basis. We have made an accounting policy election for each major security type of AFS debt securities to adjust the effective interest rate used to discount expected cash flows to consider the timing of expected cash flows resulting from expected prepayments. Impairment for noncredit-related factors is recorded in OCI, net of income taxes.

Securities sold under agreements to repurchase are accounted for as collateralized financing transactions and are recorded at the amounts at which the securities were sold plus accrued interest. Securities, generally U.S. government and federal agency securities, pledged as collateral under these financing arrangements cannot be sold or repledged by the secured party. The fair value of collateral either received from or provided to a third party is continually monitored and additional collateral is obtained or is requested to be returned to us as deemed appropriate.

From time to time, we may enter into derivative transactions principally to protect against the risk of adverse price or interest rate movements on the value of certain assets and liabilities and on future cash flows. Foreign exchange derivatives are entered into to accommodate the needs of customers. All derivative instruments are carried at fair value on the Consolidated Balance Sheets as either an asset or liability. Accounting for the changes in fair value of a derivative is dependent upon whether it has been designated in a formal, qualifying hedging relationship. For derivatives in qualifying hedging relationships, we formally document all relationships between hedging instruments and hedged items, as well as our risk management objective and strategy for undertaking each hedge transaction. Cash flows from hedging activities are classified in the same category as the items hedged.

Changes in fair value of a derivative instrument that has been designated and qualifies as a cash flow hedge, including any ineffectiveness, are recorded in AOCI, net of tax. Amounts are reclassified from AOCI to the Consolidated Statements of Income in the same line item used to present the earnings effect of the hedged item in the period or periods in which the hedged transaction affects earnings.

At the hedge’s inception, a formal assessment is performed to determine whether changes in the fair values or cash flows of the derivative instruments have been highly effective in offsetting changes in fair values or cash flows of the hedged items and whether they are expected to be highly effective in the future. At each reporting period thereafter, a statistical regression or qualitative analysis is performed to evaluate hedge effectiveness. If it is determined a derivative instrument has not been or will not continue to be highly effective as a hedge, hedge accounting is discontinued.

We also enter into interest rate swap agreements to meet the interest rate risk management needs of qualifying commercial loan customers. These agreements provide the customer the ability to convert from variable to fixed interest rates. We then enter into positions with a derivative counterparty in order to offset our exposure on the fixed components of the customer agreements. The credit risk associated with derivatives executed with customers is essentially the same as that involved in extending loans and is subject to normal credit policies and monitoring. We seek to minimize counterparty credit risk by entering into transactions with only high-quality institutions and using collateral agreements and other contract provisions. These arrangements meet the definition of derivatives, but are not designated as qualifying hedging relationships. The interest rate swap agreement with the loan customer and with the counterparty are reported at fair value in other assets and other liabilities on the Consolidated Balance Sheets with any changes in fair value recognized in current period earnings.

Certain of our residential mortgage loans are originated or purchased for sale in the secondary mortgage loan market. We make an automatic election to account for all originated or purchased residential mortgage loans held for sale under the FVO. The FVO election is intended to better reflect the underlying economics and better facilitate the economic hedging of the loans. The FVO is applied on an instrument-by-instrument basis and is an irrevocable election. Additionally, with the election of the FVO, fees and costs associated with the origination and acquisition of residential mortgage loans held for sale are expensed as incurred, rather than deferred. Changes in fair value under the FVO are recorded in mortgage banking operations non-interest income on the Consolidated Statements of Income. Fair value is determined on the basis of rates obtained in the respective secondary market for the type of loan held for sale. Gain or loss on the sale of loans is recorded in mortgage banking operations non-interest income. Interest income on loans held for sale is recorded in interest income.

We routinely issue IRLCs for residential mortgage loans that we intend to sell. These IRLCs are considered derivatives. We also enter into loan sale commitments to sell these loans when funded to mitigate the risk that the market value of residential mortgage loans may decline between the time the rate commitment is issued to the customer and the time we sell the loan. These loan sale commitments are also derivatives. Both types of derivatives are recorded at fair value on the Consolidated Balance Sheets with changes in fair value recorded in mortgage banking operations non-interest income.

We also originate loans guaranteed by the SBA for the purchase of businesses, business startups, business expansion, equipment and working capital. All SBA loans are underwritten and documented as prescribed by the SBA. SBA loans originated with the intention to sell on the secondary market are classified as held for sale and carried at the lower of cost or fair value. At the time of the sale, we allocate the carrying value of the entire loan between the guaranteed portion sold and the unguaranteed portion retained based on their relative fair value which results in a discount recorded on the retained portion of the loan. The guaranteed portion is typically sold at a premium and the gain is recognized in other income for any net premium received in excess of the relative fair value of the portion of the loan transferred. The net carrying value of the retained portion of the loans is included in the appropriate commercial loan classification for disclosure purposes.

Loans we intend to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, net of the ACL. Amortized cost primarily consists of the principal balances outstanding, deferred origination fees or costs and premiums or discounts on purchased loans. Interest income on loans is computed over the term of the loans using the effective interest method. Loan origination fees or costs, premiums or discounts are deferred and amortized over the term of the loan or loan commitment period as an adjustment to the related loan yield.

We place loans on non-accrual status and discontinue interest accruals on loans generally when principal or interest is due and has remained unpaid for a certain number of days, unless the loan is both well secured and in the process of collection. Commercial loans and leases are placed on non-accrual at 90 days, installment loans are placed on non-accrual at 120 days and residential mortgages and consumer lines of credit are generally placed on non-accrual at 180 days, though we may place a loan on non-accrual prior to these past due thresholds as warranted. When a loan is placed on non-accrual status, all unpaid accrued interest is reversed against interest income and the amortization of deferred fees and costs is suspended. Non-accrual loans may not be restored to accrual status until all delinquent principal and interest have been paid and the ultimate ability to collect the remaining principal and interest is reasonably assured. Loans are charged-off against the ACL and recoveries of amounts previously charged-off are credited to the ACL when realized.

We estimate the ACL on loans and leases using relevant available information, from internal and external sources, relating to past events, current conditions, and R&S forecasts under the CECL methodology. The ACL is measured on a collective (pool) basis when similar risk characteristics exist. Our portfolio segmentation is characterized by similarities in initial measurement, risk attributes, and the manner in which we monitor and assess credit risk and is comprised of commercial real estate, commercial and industrial, commercial leases, commercial other, direct installment, residential mortgages, indirect installment and consumer lines of credit.

The ACL on loans and leases represents our current estimate of lifetime credit losses in our loan portfolio at the balance sheet date. In determining the ACL, we estimate expected future losses for the loan's entire contractual term adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications. The ACL is the sum of three components: quantitative (formulaic or pooled) reserves; asset specific / individual loan reserves; and qualitative (judgmental) reserves.

Loans that do not share risk characteristics are generally evaluated on an individual basis. Loans evaluated individually are not included in the collective evaluation. We have elected to apply the practical expedient to measure expected credit losses of a collateral dependent asset using the fair value of the collateral, less any costs to sell.

While our reserve methodologies strive to reflect all relevant risk factors, there continues to be uncertainty associated with, but not limited to, potential imprecision in the estimation process due to the inherent time lag of obtaining information and normal variations between estimates and actual outcomes. We may adjust reserves to reflect such risks. The ACL also includes factors that may not be directly measured in the determination of individual or collective reserves. Such qualitative factors may include:

The AULC is management's estimate of credit losses inherent in our unfunded loan commitments, such as commercial and industrial revolving loan facilities, commercial real estate construction projects and home equity lines of credit, and is included in other liabilities on the Consolidated Balance Sheets. The AULC is estimated over the contractual period in which we are exposed to credit risk for obligations which are not unconditionally cancellable by us. The AULC is adjusted through provision for credit losses. 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 useful life. Consistent with our estimation process on our loan and lease portfolio, we use a non-discounted cash flow factor-based approach to estimate expected credit losses that include component PD/LGD/EAD models as well as less complex estimation methods for smaller portfolios.

We have purchased loans and leases, some of which have experienced more than insignificant credit deterioration since origination and have established criteria to assess whether a purchased financial asset, or group of assets, should be accounted for as PCD on the acquisition date. The selection of which criteria to apply, or the addition of new criteria, to a specific acquisition will be based on the facts and circumstances at the time of review, as well as the availability of information supplied by the acquiree. Generally, more-than-insignificant deterioration in credit quality since origination would include risk ratings of special mention or below, inconsistency of loan payments, non-accrual status at the time of acquisition, or loans modified in a TDM, in bankruptcy or for regulatory purposes.

PCD loans are recorded at the amount paid. The initial ACL is determined using the same methodology as other loans held for investment on a collective basis and is allocated to individual loans. The sum of the loan’s purchase price and the ACL becomes the 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 or accreted into interest income over the life of the loan. Subsequent changes to the ACL are recorded through the provision for credit losses.

Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the asset’s estimated useful life. Leasehold improvements are expensed over the lesser of the asset’s estimated useful life or the term of the lease including renewal periods when reasonably assured. Useful lives are dependent upon the nature and condition of the asset and range from 3 to 39 years. Maintenance and repairs are charged to expense as incurred, while major improvements are capitalized and amortized to expense over the identified useful life. Premises and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable.

We evaluate fees paid for cloud computing arrangements to determine if those arrangements include the purchase of or license to use software that should be accounted for separately as internal-use software. If a contract includes the purchase or license to use software that should be accounted for separately as internal-use software, the contract is amortized over the software’s identified useful life in amortization of intangibles. For contracts that do not include a software license, the contract is accounted for as a service contract with fees paid recorded in other non-interest expense.

OREO is comprised principally of commercial and residential real estate properties obtained in partial or total satisfaction of loan obligations. OREO acquired in settlement of indebtedness is included in other assets initially at fair value of the asset less estimated selling costs. Subsequent to acquisition, OREO is accounted for at the lower of amortized cost or fair value less estimated selling costs. Changes to the value subsequent to transfer are recorded in non-interest expense along with direct operating expenses. Gains or losses not previously recognized resulting from sales of OREO are recognized in non-interest income on the date of sale.

Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. Intangible assets that have finite lives, such as core deposit intangibles, customer relationship intangibles and renewal lists, are amortized over their estimated useful lives and subject to periodic impairment testing. Core deposit intangibles are primarily amortized over ten years using accelerated methods. Customer renewal lists are amortized over their estimated useful lives which range from eight to thirteen years.

Goodwill and other intangibles are subject to impairment testing at the reporting unit level, which must be conducted at least annually. We perform impairment testing during the fourth quarter of each year, or more frequently if impairment indicators exist. We also continue to monitor other intangibles for impairment and to evaluate carrying amounts, as necessary.

Quarterly, we perform a goodwill impairment assessment. We first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. Qualitative factors include, among other things, macroeconomic conditions, industry and market considerations, financial performance of the respective reporting unit and other relevant entity- and reporting-unit specific considerations. If we conclude it is more likely than not that the fair value of a reporting unit is less than its carrying value, a quantitative assessment is performed. If the quantitative assessment results in the fair value of the reporting unit exceeding its carrying value, goodwill of the reporting unit is considered not impaired; however, if the carrying value of the reporting unit exceeds its fair value, an impairment charge is recorded for the excess, limited to the amount of goodwill assigned to a reporting unit.

Determining the fair value of a reporting unit under the goodwill impairment test is judgmental and often involves the use of significant estimates and assumptions. Similarly, estimates and assumptions are used in determining the fair value of other intangible assets. Estimates of fair value are primarily determined using discounted cash flows, market comparisons and recent transactions. These approaches use significant estimates and assumptions including projected future cash flows, discount rates reflecting the market rate of return, projected growth rates and determination and evaluation of appropriate market comparables.

We have two primary classes of servicing rights, residential mortgage loan servicing and SBA-guaranteed loan servicing. We recognize the right to service residential mortgage loans and SBA-guaranteed loans for others as an asset whether we purchase the servicing rights or as a result from a sale of loans that we originated or purchased when the servicing is contractually separated from the underlying loan and retained by us.

We initially record servicing rights at fair value in other assets on the Consolidated Balance Sheets. Subsequently, servicing rights are measured at the lower of cost or fair value. Servicing rights are amortized in proportion to, and over the period of, estimated net servicing income in mortgage banking operations non-interest income for residential mortgage loans and other non-interest income for SBA-guaranteed loans. The amount and timing of estimated future net cash flows are updated based on actual results and updated projections.

MSRs are separated into pools based on common risk characteristics of the underlying loans and evaluated for impairment at least quarterly. SBA-guaranteed servicing rights are evaluated for impairment at least quarterly on an aggregate basis. Impairment, if any, is recognized when carrying value exceeds the fair value as determined by calculating the present value of expected net future cash flows. If impairment exists at the pool level for residential mortgage loans or on an aggregate basis for SBA-guaranteed loans, the servicing right is written down through a valuation allowance and is charged against mortgage banking operations non-interest income or other non-interest income, respectively.

We have purchased life insurance policies on certain current and former directors, officers and employees for which the Corporation is the owner and beneficiary. These policies are recorded in the Consolidated Balance Sheets at their cash surrender value, or the amount that could be realized by surrendering the policies. Tax-exempt income from death benefits and changes in the net cash surrender value are recorded in BOLI non-interest income.

We invest in various affordable housing projects that qualify for LIHTCs. The net investments are recorded in other assets on the Consolidated Balance Sheets. These investments generate a return through the realization of federal tax credits. We use the proportional amortization method to account for a majority of our investments in these entities. LIHTCs that do not meet the requirements of the proportional amortization method are recognized using the equity method.

We determine if an arrangement is, or contains, a lease at inception of the contract. As a lessee, we consider a contract to be, or contain, a lease if the contract conveys the right to control the use of an identified asset in exchange for consideration. We recognize in our Consolidated Balance Sheets the obligation to make lease payments and a right-of-use asset representing our right to use the underlying asset for the lease term. For an operating lease, the right-of-use asset and lease liability are included in other assets and other liabilities, respectively. Finance leases are included in premises and equipment, and other liabilities. We do not record leases with an initial term of 12 months or less on the Consolidated Balance Sheets, instead we recognize lease expense for these leases on a straight-line basis over the lease term.

Right-of-use assets and liabilities are initially measured at the present value of lease payments over the lease term, discounted using the interest rate implicit in the lease at the commencement date. Right-of-use assets are adjusted for any lease payments made prior to lease commencement, lease incentives, and accrued rent. If the rate implicit in the lease cannot be readily determined, we discount the lease using our incremental borrowing rate which is derived by reference to FNB's secured borrowing rate. Our leases may include options to extend or terminate the lease. When it is reasonably certain that we will exercise such an option, the lease term includes those periods. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Lease expense for finance leases is recognized using the effective interest method. Certain of our lease agreements include variable rental payments based on a percentage of transactions and others include variable rental payments that periodically adjust to rates and charges stated in the agreements. Variable costs, such as maintenance expenses, property taxes, property insurance, transaction-based lease payments and index-based rate increases, are expensed as incurred. Right-of-use assets are reviewed for impairment when events or circumstances indicate that the carrying amount may not be recoverable. For operating leases, if deemed impaired, the right-of-use asset is written down and the remaining balance is subsequently amortized on a straight-line basis. We have real estate lease agreements with lease and non-lease components, which are generally accounted for as a single lease component.

As a lessor, when a lease meets certain criteria indicating that we effectively have transferred control of the underlying asset to the customer, the lease is classified as a sales-type lease. When a lease does not meet the criteria for a sales-type lease but meets the criteria of a direct financing lease, the lease is classified as a direct financing lease. When none of the required criteria for sales-type lease or direct-financing lease are met, the lease is classified as an operating lease.

Both sales-type leases and direct financing leases are recognized as a net investment in the lease on the Consolidated Balance Sheets. The net investment comprises the lease receivable including any residual value of the underlying asset that is guaranteed by the customer or any other third party unrelated to us and the unguaranteed residual value of the underlying asset. Operating lease income is recognized over the lease term on a straight-line basis. We do not evaluate whether sales taxes and similar taxes imposed by a governmental authority on lease transactions and collected by us are our primary obligation as owner of the underlying leased asset and exclude from lease income all taxes collected.

In determining the appropriate revenue recognition for our contracts with customers, we consider whether the contract has commercial substance and is approved by both parties with identifiable contractual rights, payment terms, and the collectability of consideration is probable. Generally, we satisfy our performance obligations upon the completion of services at the amount to which we have the right to invoice or charge under contracts with an original expected duration of one year or less. We apply this guidance on a portfolio basis to contracts with similar characteristics and for which we believe the results would not differ materially from applying this guidance to individual contracts.

Our services provided under contracts with customers are transferred at the point in time when the services are rendered. Generally, we do not defer incremental direct costs to obtain contracts with customers that would be amortized in one year or less under the practical expedient. These costs are recognized as expense, primarily salary and benefit expense, in the period incurred.

Deposit Services. We recognize revenue on deposit services based on published fees for services provided. Demand and savings deposit customers have the right to cancel their depository arrangements and withdraw their deposited funds at any time without prior notice. When services involve deposited funds that can be retrieved by customers without penalties, we consider the service contract term to be day-to-day, where each day represents the renewal of the contract. The contract does not extend beyond the services performed and revenue is recognized at the end of the contract term (daily) as the performance obligation is satisfied.

Revenues from deposit services fees are reduced where we have a history of waived or reduced fees by customer request or due to a customer service issue, by historical experience, or another acceptable method in the same period as the related revenues. Revenues from deposit services are reported in the Consolidated Statements of Income as service charges and in the Community Banking segment as non-interest income.

Wealth Management Services. Wealth advisory and trust services are provided on a month-to-month basis and invoiced as services are rendered. Fees are based on a fixed amount, or a scale based on the level of services provided or assets under management. The customer has the right to terminate their services agreement at any time. We determine the value of services performed based on the fee schedule in effect at the time the services are performed. Revenues from wealth advisory and trust services are reported in the Consolidated Statements of Income as trust services and securities commissions and fees, and in the Wealth segment as non-interest income.

Insurance Services. Insurance services include full-service insurance brokerage services offering numerous lines of commercial and personal insurance through major carriers to businesses and individuals within our geographic markets. We recognize revenue on insurance contracts in effect based on contractually specified commission payments on premiums that are paid by the customer to the insurance carrier. Contracts are cancellable at any time, and we have no performance obligation to the customers beyond the time the insurance is placed into effect. Revenues from insurance services are reported in the Consolidated Statements of Income as insurance commissions and fees, and in the Insurance segment in the Business Segments footnote as non-interest income.

Other Services. Other services primarily consist of fees generated from various ancillary revenue streams including capital markets revenue and miscellaneous consumer fees. A large portion of capital markets revenue consists of swap fee income, and this income is recognized during the period of swap execution. Revenues from other services are recognized when, or as, the performance obligation is satisfied and are reported in the Consolidated Statements of Income as non-interest income.

We file a consolidated federal income tax return. The provision for federal and state income taxes is based on income reported on the Consolidated Financial Statements, rather than the amounts reported on the respective income tax returns. DTAs and DTLs are computed using tax rates expected to apply to taxable income in the years in which those assets and liabilities are

We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments are applied in the calculation of certain tax credits and in the calculation of the deferred income tax expense or benefit associated with certain DTAs and DTLs. Significant changes to these estimates may result in an increase or decrease to our tax provision in a subsequent period. We recognize interest and/or penalties related to income tax matters in income tax expense.

We periodically review the tax positions we take on our tax return and apply a more likely than not recognition threshold for all tax positions that are uncertain. The amount recognized in the Consolidated Financial Statements is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the more likely than not test, no tax benefit is recorded.

Diluted earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding, adjusted for the dilutive effect of potential common shares issuable for stock options and restricted shares, as calculated using the treasury stock method. Adjustments to net income available to common stockholders and the weighted average number of shares of common stock outstanding are made only when such adjustments dilute earnings per common share. The assumed proceeds from applying the treasury stock method when computing diluted earnings per share excludes the amount of excess tax benefits that would have been recognized in accumulated paid-in capital.

We sponsor retirement plans for our employees. The calculation of the obligations and related expenses under these plans requires use of actuarial valuation methods and assumptions. The plans utilize assumptions and methods including reflecting trust assets at their fair value for the qualified pension plans and recognizing the overfunded and underfunded status of the plans on our Consolidated Balance Sheets. Gains and losses, prior service costs and credits are recognized in AOCI, net of tax, until they are amortized, or immediately upon curtailment.

Our stock-based compensation awards require the measurement and recognition of compensation expense, based on estimated fair values, for all stock-based awards, including stock options and restricted stock units, made to employees and stock awards made to directors. Generally, these restricted stock unit awards to employees vest over a three-year service period and the stock awards made to non-employee directors vest over a one-year period.
