Note 1 – Significant Accounting Policies

Business

Trustmark Corporation (Trustmark) is a bank holding company headquartered in Jackson, Mississippi. Through its subsidiaries, Trustmark operates as a financial services organization providing banking and financial solutions to corporate institutions and individual customers through offices in Alabama (includes the Georgia Loan Production Office), Florida, Mississippi, Tennessee and Texas.

Basis of Financial Statement Presentation

The consolidated financial statements include the accounts of Trustmark and all other entities in which Trustmark has a controlling financial interest. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to prior period amounts to conform to the current period presentation.

The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (GAAP). The preparation of financial statements in conformity with these accounting principles requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and income and expense during the reporting periods and the related disclosures. Although Management’s estimates contemplate current conditions and how they are expected to change in the future, it is reasonably possible that in 2024 actual conditions could vary from those anticipated, which could affect Trustmark’s financial condition and results of operations. Actual results could differ from those estimates.

Securities

Securities are classified as either held to maturity or available for sale. Securities are classified as held to maturity and carried at amortized cost when Management has the positive intent and the ability to hold them until maturity. Securities to be held for indefinite periods of time are classified as available for sale and carried at fair value, with the unrealized holding gains and losses reported as a component of other comprehensive income (loss), net of tax. Securities available for sale are used as part of Trustmark’s interest rate risk management strategy and may be sold in response to changes in interest rates, changes in prepayment rates and other factors. Management determines the appropriate classification of securities at the time of purchase.

The amortized cost of debt securities classified as securities held to maturity or securities available for sale is adjusted for amortization of premiums and accretion of discounts to maturity of the security using the interest method. Such amortization or accretion is included in interest on securities. Realized gains and losses are determined using the specific identification method and are included in noninterest income as securities gains (losses), net.

Securities transferred from the available for sale category to the held to maturity category are recorded at fair value at the date of transfer. Unrealized holding gains or losses associated with the transfer of securities from available for sale to held to maturity are included in the balance of accumulated other comprehensive income (loss), net of tax, in the consolidated balance sheets. These unrealized holding gains or losses are amortized over the remaining life of the security as a yield adjustment in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security.

Allowance for Credit Losses (ACL)

Financial Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 326 requires a current expected credit losses methodology for estimating allowances for credit losses and applies to all financial instruments carried at amortized cost, including securities held to maturity, and makes targeted improvements to the accounting for credit losses on securities available for sale.

Under FASB ASC Topic 326, the ACL is an estimate measured using relevant information about past events, including historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets.

Trustmark adopted a zero-credit loss assumption for certain classes of securities. This zero-credit loss assumption applies to debt issuances of the U.S. Treasury and agencies and instrumentalities of the United States government. The reasons behind the adoption of the zero-credit loss assumption were as follows:

•High credit rating

•Long history with no credit losses

•Guaranteed by a sovereign entity

•Widely recognized as “risk-free rate”

•Ability and authority to print its own currency

•Currency is routinely held by central banks, used in international commerce, and commonly viewed as reserve currency

•Currently under the U.S. Government conservatorship or receivership

Trustmark continuously monitors any changes in economic conditions, credit downgrades, changes to explicit or implicit guarantees granted to certain debt issuers, and any other relevant information that would indicate potential credit deterioration and prompt Trustmark to reconsider its zero-credit loss assumption.

Securities Available for Sale

FASB ASC Subtopic 326-30, “Financial Instruments-Credit Losses-Available-for-Sale Debt Securities,” replaced the concept of other-than-temporarily impaired with the ACL. Unlike securities held to maturity, securities available for sale are evaluated on an individual level and pooling of securities is not allowed.

Quarterly, Trustmark evaluates if any security has a fair value less than its amortized cost. Once these securities are identified, in order to determine whether a decline in fair value resulted from a credit loss or other factors, Trustmark performs further analysis as outlined below:

•Review the extent to which the fair value is less than the amortized cost and observe the security’s lowest credit rating as reported by third-party credit ratings companies.

•The securities that violate the credit loss triggers above would be subjected to additional analysis that may include, but is not limited to: changes in market interest rates, changes in securities credit ratings, security type, service area economic factors, financial performance of the issuer/or obligor of the underlying issue and third-party guarantee.

•If Trustmark determines that a credit loss exists, the credit portion of the allowance will be measured using a discounted cash flow (DCF) analysis using the effective interest rate as of the security’s purchase date. The amount of credit loss Trustmark records will be limited to the amount by which the amortized cost exceeds the fair value.

The DCF analysis utilizes contractual maturities, as well as third-party credit ratings and cumulative default rates published annually by Moody’s Investor Service (Moody’s).

Accrued interest receivable is excluded from the estimate of credit losses for securities available for sale and reported in other assets on the consolidated balance sheets.

Securities Held to Maturity

FASB ASC Subtopic 326-20, “Financial Instruments-Credit Losses-Measured at Amortized Cost,” requires institutions to measure expected credit losses on financial assets carried at amortized cost on a collective or pool basis when similar risks exist. Trustmark uses several levels of segmentation to measure expected credit losses for its held to maturity securities:

•The portfolio is segmented into agency and non-agency securities.

•The non-agency securities are separated into municipal, mortgage, and corporate securities.

•Each individual segment is categorized by third-party credit ratings.

As discussed above, Trustmark has determined that for certain classes of securities it would be appropriate to assume the expected credit loss to be zero, which include debt issuances of the U.S. Treasury and agencies and instrumentalities of the United States government. This assumption is reviewed and attested to quarterly. Trustmark uses an internally built model to verify the accuracy of third-party provided calculations.

Accrued interest receivable is excluded from the estimate of credit losses for securities held to maturity and included in other assets on the consolidated balance sheets.

Trustmark monitors the credit quality of securities held to maturity on a monthly basis through credit ratings.

Loans Held for Sale (LHFS)

Trustmark's LHFS portfolio consists of mortgage loans purchased from wholesale customers or originated in Trustmark’s General Banking Segment. Trustmark has elected to account for its LHFS under the fair value option permitted by FASB ASC Topic 825, “Financial Instruments,” with interest income on the LHFS reported in interest and fees on LHFS and LHFI. Trustmark reports unrealized gains and losses resulting from changes in the fair value of the LHFS accounted for under the fair value option as noninterest income in mortgage banking, net. LHFS are actively managed and monitored and certain market risks of the loans may be mitigated through the use of derivatives. These derivative instruments are carried at fair value with changes in the fair value reported as noninterest income in mortgage banking, net. Changes in the fair value of the LHFS are largely offset by changes in the fair value of the derivative instruments. Election of the fair value option allows Trustmark to reduce the accounting volatility that would otherwise result from the asymmetry created by accounting for its LHFS at the lower of cost or fair value and the derivative instruments at fair value. Realized gains and losses upon ultimate sale of the loans are reported as noninterest income in mortgage banking, net.

Government National Mortgage Association (GNMA) optional repurchase programs allow financial institutions to buy back individual delinquent mortgage loans that meet certain criteria from the securitized loan pool for which the institution provides servicing. At the servicer’s option and without GNMA’s prior authorization, the servicer may repurchase such a delinquent loan for an amount equal to 100 percent of the remaining principal balance of the loan. Under FASB ASC Topic 860, “Transfers and Servicing,” this buy-back option is considered a conditional option until the delinquency criteria are met, at which time the option becomes unconditional. When Trustmark is deemed to have regained effective control over these loans under the unconditional buy-back option, the loans can no longer be reported as sold and must be brought back onto the balance sheet as LHFS, regardless of whether Trustmark intends to exercise the buy-back option. These loans are reported as LHFS with the offsetting liability being reported as short-term borrowings. The fair value option election does not apply to the GNMA optional repurchase loans which do not meet the requirements under FASB ASC Topic 825 to be accounted for under the fair value option.

Trustmark defers the upfront loan fees and costs related to the LHFS. In general, the LHFS are only retained on Trustmark’s balance sheet for 30 to 45 days before they are pooled and sold in the secondary market. The difference between deferring these loan fees and costs until the loans are sold and recognizing them in earnings as incurred as required by FASB ASC Subtopic 825-10 is considered immaterial. Deferred loan fees and costs are reflected in the basis of the LHFS and, as such, impact the resulting gain or loss when the loans are sold.

Loans Held for Investment (LHFI)

LHFI are loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off and are reported at amortized cost net of the ACL. Amortized cost is the amount of unpaid principal, adjusted for the net amount of direct costs and nonrefundable loan fees associated with lending. The net amount of nonrefundable loan origination fees and direct costs associated with the lending process, including commitment fees, is deferred and accreted to interest income over the lives of the loans using a method that approximates the interest method. Interest on LHFI is accrued and recorded as interest income based on the outstanding principal balance.

Past due LHFI are loans contractually past due 30 days or more as to principal or interest payments. A LHFI is classified as nonaccrual, and the accrual of interest on such loan is discontinued, when the contractual payment of principal or interest becomes 90 days past due on commercial credits and 120 days past due on non-business purpose credits. In addition, a credit may be placed on nonaccrual at any other time Management has serious doubts about further collectability of principal or interest according to the contractual terms, even though the loan is currently performing. A LHFI may remain in accrual status if it is in the process of collection and well-secured. When a LHFI is placed in nonaccrual status, interest accrued but not received is reversed against interest income. Interest payments received on nonaccrual LHFI are applied against principal under the cost-recovery method, until qualifying for return to accrual status. Under the cost-recovery method, interest income is not recognized until the principal balance is reduced to zero. LHFI are restored to accrual status when the ultimate collectability of the total contractual principal and interest is no longer in doubt and the obligation has either been brought current or has performed in accordance with the contractual terms for a reasonable period of time.

Purchased Credit Deteriorated (PCD) Loans

Purchased loans which have experienced more than insignificant credit deterioration since origination are considered PCD loans. An initial ACL for PCD loans is determined at acquisition using the same ACL methodology as the LHFI. The initial ACL determined on a collective basis is allocated to individual loans. PCD loans are reported at the amortized cost, which equals the loan purchased price plus the initial ACL. The difference between the amortized cost basis of the PCD loan and the par value of the loan is the noncredit premium or discount, which is amortized into interest income over the life of the loan. Subsequent changes to the ACL are recorded through the PCL, LHFI.

Upon adoption of FASB ASC Topic 326, Trustmark elected to maintain pools of loans that were previously accounted for under FASB ASC Subtopic 310-30, “Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality,” and will continue to account for these pools as a unit of account. Loans are only removed from the existing loan pools if they are written off, paid off or sold. Upon adoption of FASB ASC Topic 326, the ACL was determined for each pool and added to the pool’s carrying value to establish a new amortized cost basis. The difference between the unpaid principal balance of the pool and the new amortized cost basis is the noncredit premium or discount which will be amortized into interest income over the remaining life of the pool. Changes to the ACL after adoption of FASB ASC Topic 326 are recorded through the PCL, LHFI.

ACL

LHFI

Trustmark’s ACL methodology for LHFI is based upon guidance within FASB ASC Subtopic 326-20 as well as applicable regulatory guidance. The ACL on LHFI 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. Credit quality within the LHFI portfolio is continuously monitored by Management and is reflected within the ACL on LHFI. The ACL on LHFI is an estimate of expected losses inherent within Trustmark’s existing LHFI portfolio. The ACL on LHFI is adjusted through the PCL, LHFI and reduced by the charge off of loan amounts, net of recoveries.

The loan loss estimation process involves procedures to appropriately consider the unique characteristics of Trustmark’s LHFI portfolio segments. These segments are further disaggregated into loan classes, the level at which credit risk is estimated. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, delinquency status and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Evaluations of the portfolio and individual credits are inherently subjective, as they require estimates, assumptions and judgments as to the facts and circumstances of particular situations. Determining the appropriateness of the allowance is complex and requires judgment by Management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall LHFI portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense.

Trustmark estimates the ACL on LHFI using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Trustmark uses a third-party software application to calculate the quantitative portion of the ACL on LHFI using a methodology and assumptions specific to each loan pool. The qualitative portion of the allowance is based on general economic conditions and other internal and external factors affecting Trustmark as a whole as well as specific LHFI. Factors considered include the following: lending policies and procedures, economic conditions and concentrations of credit, nature and volume of the portfolio, performance trends, and external factors. The quantitative and qualitative portions of the allowance are added together to determine the total ACL on LHFI, which reflects Management’s expectations of future conditions based on reasonable and supportable forecasts.

The methodology for estimating the amount of expected credit losses reported in the ACL on LHFI has two basic components: a collective, or pooled, component for estimated expected credit losses for pools of loans that share similar risk characteristics, and an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. In estimating the ACL for the collective component, loans are segregated into loan pools based on loan product types and similar risk characteristics.

Trustmark determined that reasonable and supportable forecasts could be made for a twelve-month period for all of its loan pools. To the extent the lives of the loans in the LHFI portfolio extend beyond this forecast period, Trustmark uses a reversion period of four quarters and reverts to the historical mean on a straight-line basis over the remaining life of the loans.

The ACL for individual loans that do not share risk characteristics with other loans is measured as the difference between the discounted value of expected future cash flows, based on the effective interest rate at origination, and the amortized cost basis of the loan, or the net realizable value. The ACL is the difference between the loan’s net realizable value and its amortized cost basis (net of previous charge-offs and deferred loan fees and costs), except for collateral-dependent loans. A loan is collateral dependent when the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the sale of the collateral. The expected credit loss for collateral-dependent loans is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral, adjusted for the estimated cost to sell. Fair value estimates for collateral-dependent loans are derived from appraised values based on the current market value or the ‘as is’ value of the collateral, normally from recently received and reviewed appraisals. Current appraisals are ordered on an annual basis based on the inspection date or more often if market conditions necessitate. Appraisals are obtained from state-certified appraisers and are based on certain assumptions, which may include construction or development status and the highest and best use of the property. These appraisals are reviewed by Trustmark’s Appraisal Review Department to ensure they are acceptable, and values are adjusted down for costs associated with asset disposal. If the calculated expected credit loss is determined to be permanent or not recoverable, the amount of the expected credit loss is charged off.

Accrued interest receivable is not included in the amortized cost basis of Trustmark’s LHFI and, therefore, excluded from the estimate of credit losses for LHFI.

LHFI are charged off against the ACL on LHFI, with any subsequent recoveries credited back to the ACL on LHFI account. Recoveries may not exceed the aggregate of amounts previously charged off. Trustmark’s Loan Policy Manual dictates the guidelines to be followed in determining when a loan is charged off. Commercial purpose LHFI are charged off when a determination is made that the loan is uncollectible and continuance as a bankable asset is not warranted. Consumer LHFI secured by 1-4 family residential real estate are generally charged off or written down to the fair value of the collateral less cost to sell at no later than 180 days of delinquency. Non-real estate consumer purpose LHFI, including both secured and unsecured loans, are generally charged off by 120 days of delinquency. Consumer revolving lines of credit and credit card debt are generally charged off on or prior to 180 days of delinquency.

ACL on Off-Balance Sheet Credit Exposures

Under FASB ASC Subtopic 326-20, Trustmark is required to estimate expected credit losses for off-balance sheet credit exposures which are not unconditionally cancellable. Trustmark maintains a separate ACL on off-balance sheet credit exposures, including unfunded loan commitments and letters of credit.

Expected credit losses for off-balance sheet credit exposures are estimated by calculating a commitment usage factor over the contractual period for exposures that are not unconditionally cancellable by Trustmark. Trustmark calculates a loan pool level unfunded amount for the period. Trustmark views the loan pools as either closed-ended or open-ended. Closed-ended loan pools are those that typically fund up to 100% such as other construction and nonowner-occupied. Open-ended loan pools are those that behave similar to a revolver such as the commercial and industrial and home equity line of credit loan pools. In addition to the unfunded balances, Trustmark uses a funding rate for loan pools that are considered open-ended. Trustmark calculates the funding rate of the open-ended loan pools each period. In order to mitigate volatility and incorporate historical experience in the funding rate, Trustmark uses a twelve-quarter moving average. For the closed-ended loan pools, Trustmark takes a conservative approach and uses a 100% funding rate. The expected funding rate is applied to each pool’s unfunded commitment balances to ensure that reserves will be applied to each pool based on balances expected to be funded based upon historical levels. In addition to the funding rate being applied to the unfunded commitment balance, a reserve rate is applied that incorporates both quantitative and qualitative aspects of the current period’s expected credit loss rate. The reserve rate is loan pool specific and is applied to the unfunded amount to ensure loss factors, both quantitative and qualitative, are being considered on the unfunded portion of the loan pool, consistent with the methodology applied to the funded loan pools. Adjustments to the ACL on off-balance sheet credit exposures are recorded to the PCL, off-balance sheet credit exposures.

No credit loss estimate is reported for off-balance sheet credit exposures that are unconditionally cancellable by Trustmark or for undrawn amounts under such arrangements that may be drawn prior to the cancellation of the arrangement.

Premises and Equipment, Net

Premises and equipment are reported at cost, less accumulated depreciation and amortization. Depreciation is charged to expense over the estimated useful lives of the assets, which are up to thirty-nine years for buildings and three to ten years for furniture and equipment. Leasehold improvements are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. In cases where Trustmark has the right to renew the lease for additional periods, the lease term for the purpose of calculating amortization of the capitalized cost of the leasehold improvements is extended when Trustmark is “reasonably assured” that it will renew the lease. Depreciation and amortization expenses are computed using the straight-line method. Trustmark continually evaluates whether events and circumstances have occurred that indicate that such long-lived assets have become impaired. Measurement of any impairment of such long-lived assets is based on the fair values of those assets.

Branch closures and purchased land held for future branch expansion for more than five years are evaluated to determine if the related land, buildings and building improvements should be transferred to assets held for sale in accordance with FASB ASC Topic 360, “Property, Plant and Equipment.” The property is transferred to assets held for sale at the lower of its carrying value or fair value less cost to sell. An impairment loss is recorded at the time of transfer if the carrying value of the assets exceeds the fair value. Impairment losses are recorded as noninterest expense in other expense.

Mortgage Servicing Rights (MSR)

Trustmark recognizes as assets the rights to service mortgage loans based on the estimated fair value of the MSR when loans are sold and the associated servicing rights are retained. Trustmark has elected to account for the MSR at fair value.

The fair value of the MSR is determined using a valuation model administered by a third party that calculates the present value of estimated future net servicing income. Estimates of fair value involve several assumptions, including the key valuation assumptions

about market expectations of future prepayment rates, interest rates and discount rates which are provided by a third-party firm. Prepayment rates are projected using an industry standard prepayment model. The model considers other key factors, such as a wide range of standard industry assumptions tied to specific portfolio characteristics such as remittance cycles, escrow payment requirements, geographic factors, foreclosure loss exposure, VA no-bid exposure, delinquency rates and cost of servicing, including base cost and cost to service delinquent mortgages. Prevailing market conditions at the time of analysis are factored into the accumulation of assumptions and determination of servicing value.

Trustmark economically hedges changes in the fair value of the MSR attributable to interest rates. See the section titled “Derivative Financial Instruments – Derivatives Not Designated as Hedging Instruments” of this note for information regarding these derivative instruments.

Trustmark receives annual servicing fee income for loans serviced, which is recorded as noninterest income in mortgage banking, net. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees related to loan servicing are not considered material.

Goodwill and Identifiable Intangible Assets

Trustmark accounts for goodwill and other intangible assets in accordance with FASB ASC Topic 350, “Intangibles – Goodwill and Other.” Goodwill, which represents the excess of cost over the fair value of the net assets of an acquired business, is not amortized but tested for impairment on an annual basis, which is October 1 for Trustmark, or more often if events or circumstances indicate that there may be impairment.

Identifiable intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or legal rights or because the assets are capable of being sold or exchanged either on their own or in combination with a related contract, asset or liability. Trustmark’s identifiable intangible assets primarily relate to core deposits, insurance customer relationships and borrower relationships. These intangibles, which have definite useful lives, are amortized on an accelerated basis over their estimated useful lives. In addition, these intangibles are evaluated for impairment whenever events and changes in circumstances indicate that the carrying amount should be reevaluated. Trustmark also purchased banking charters in order to facilitate its entry into the states of Florida and Texas. These identifiable intangible assets are being amortized on a straight-line method over 20 years.

Other Real Estate

Other real estate includes assets that have been acquired in satisfaction of debt through foreclosure and is recorded at the fair value less cost to sell (estimated fair value) at the time of foreclosure. Fair value is based on independent appraisals and other relevant factors. When foreclosed real estate is received in full satisfaction of a loan, the amount, if any, by which the recorded amount of the loan exceeds the estimated fair value of the property is a loss charged against the ACL at the time of foreclosure. If the recorded amount of the loan is less than the estimated fair value of the property, a credit is recorded to write-downs of other real estate at the time of foreclosure.

Other real estate is revalued on an annual basis or more often if market conditions necessitate. An other real estate specific reserve may be recorded through other real estate expense for declines in fair value subsequent to foreclosure based on recent appraisals or changes in market conditions. Subsequent to foreclosure, losses on the periodic revaluation of the property are charged against an existing other real estate specific reserve or as noninterest expense in other real estate expense if a reserve does not exist. Costs of operating and maintaining the properties as well as gains or losses on their disposition are also included in other real estate expense as incurred. Improvements made to properties are capitalized if the expenditures are expected to be recovered upon the sale of the properties.

Leases

Lessor Arrangements

Trustmark leases certain types of machinery and equipment to its commercial customers through sales-type and direct financing leases as part of its equipment financing portfolio. Sales-type and direct financing leases are similar to other forms of installment lending in that lessors generally do not retain benefits and risks incidental to ownership of the property subject to the leases. Such arrangements are essentially financing transactions that permit lessees to acquire and use property. Trustmark does not have any significant operating leases in which it is the lessor.

As lessor, the sum of all minimum lease payments over the lease term and the estimated residual value, less unearned interest income, is recorded as the net investment in the lease on the commencement date and is included in LHFI on the consolidated balance sheets. Interest income is accrued as earned over the term of the lease based on the net investment in the leases and is recognized in

interest and fees on LHFS and LHFI on the consolidated statements of income. Certain fees or costs associated with lease originations are deferred and accreted or amortized to interest income over the life of the lease using the effective interest method.

Trustmark’s portfolio of sales-type and direct financing leases generally have remaining lease terms of three to ten years, some of which include renewal options and/or options for the lessee to purchase the leased property near or at the end of the lease term at either the residual value or a specified price. Trustmark expects to sell or release the equipment at the end of the lease term. Due to the structure of these leases, there is no selling profit or loss on these transactions.

Lessee Arrangements

Trustmark has certain contracts that it has identified as leases according to FASB ASC Topic 842, "Leases". Trustmark classifies these leases as either operating or finance leases and recognizes a right-of-use asset and a lease liability at the lease commencement date. The lease liability represents the present value of the lease payments that remain unpaid as of the commencement date and the right-of-use asset is the initial lease liability recognized for the lease plus any lease payments made to the lessor at or before the commencement date as well as any initial direct costs less any lease incentives received. Trustmark accounts for the lease and nonlease components separately as such amounts are readily determinable.

Trustmark’s finance leases consist of building and equipment leases. Trustmark recognizes interest expense based on the discount rate of the lease as interest expense in other interest expense and recognizes depreciation expense on a straight-line basis over the lease term as noninterest expense in net occupancy – premises for building leases and in equipment expense for equipment leases. Trustmark amortizes the right-of-use asset over the life of the lease term on a straight-line basis. Trustmark’s lease liabilities are measured as the present value of the remaining lease payments throughout the lease term. Trustmark records its finance lease right-of-use assets in premises and equipment, net and its finance lease liabilities in other borrowings.

Trustmark’s operating leases primarily consist of building and land leases. Trustmark recognizes lease rent expense on a straight-line basis over the term of the lease contract and records it as noninterest expense in net occupancy – premises for building and land leases and in equipment expense for equipment leases. Trustmark’s amortization of the right-of-use asset is the difference between the straight-line lease expense and the interest expense recognized on the lease liability during the period. Trustmark’s lease liabilities are measured as the present value of the remaining lease payments throughout the lease term.

Trustmark’s leases typically have one or more renewal options included in the lease contract. Due to the nature of Trustmark’s leases, for leases with renewal options available, Trustmark considers the first renewal option as reasonably certain to renew and is therefore included in the measurement of the right-of-use assets and lease liabilities.

In order to calculate its right-of-use assets and lease liabilities, FASB ASC Topic 842 requires Trustmark to use the rate of interest implicit in the lease when readily determinable. If the rate implicit in the lease is not readily determinable, Trustmark is required to use its incremental borrowing rate, which is the rate of interest Trustmark would have to pay to borrow on a collateralized basis over a similar term in a similar economic environment. Trustmark was able to determine the implicit interest rate for its equipment leases and used that rate as its discount rate. Since the implicit interest rate for most of its building and land leases were not readily determinable, Trustmark used its incremental borrowing rate.

Trustmark made an accounting policy election to not recognize short-term leases (12 months or less) on the balance sheet. Trustmark’s short-term leases primarily include automated teller machines. For short-term leases, Trustmark recognizes lease expense on a straight-line basis over the lease term.

Federal Home Loan Bank (FHLB) and Federal Reserve Bank of Atlanta Stock

Trustmark accounts for its investments in FHLB and Federal Reserve Bank of Atlanta stock in accordance with FASB ASC Subtopic 942-325, “Financial Services-Depository and Lending-Investments-Other.” FHLB and Federal Reserve Bank stock are equity securities that do not have a readily determinable fair value because its ownership is restricted and it lacks a market. FHLB and Federal Reserve Bank stock are carried at cost and evaluated for impairment. Trustmark’s investment in member bank stock is included in other assets in the accompanying consolidated balance sheets. At December 31, 2023 and 2022, Trustmark’s investment in member bank stock totaled $54.4 million and $72.2 million, respectively. The carrying value of Trustmark’s member bank stock gave rise to no other-than-temporary impairment for the years ended December 31, 2023, 2022 and 2021.

Revenue from Contracts with Customers

Trustmark accounts for revenue from contracts with customers in accordance with FASB ASC Topic 606, “Revenue from Contracts with Customers,” which provides that revenue be recognized in a manner that depicts the transfer of goods or services to a customer in

an amount that reflects the consideration Trustmark expects to be entitled to in exchange for those goods or services. Revenue from contracts with customers is recognized either over time in a manner that depicts Trustmark’s performance, or at a point in time when control of the goods or services are transferred to the customer. Trustmark’s noninterest income, excluding all of mortgage banking, net and securities gains (losses), net and portions of bank card and other fees and other income, are considered within the scope of FASB ASC Topic 606. Gains or losses on the sale of other real estate, which are included in Trustmark’s noninterest expense as other real estate expense, are also within the scope of FASB ASC Topic 606.

General Banking Segment

Service Charges on Deposit Accounts

In general, deposit accounts represent contracts with customers with no fixed duration and can be terminated or modified by either party at any time without compensation to the other party. According to FASB ASC Topic 606, a contract that can be terminated by either party without compensation does not exist for periods beyond the then-current period. Therefore, deposit contracts are considered to renew day-to-day if not minute-to-minute.

Deposit contracts have a single continuous or stand-ready service obligation whereby Trustmark makes customer funds available for use by the customer as and when the customer chooses as well as other services such as statement rendering and online banking. The specific services provided vary based on the type of deposit account. These services are not individually distinct, but are distinct as a group, and therefore, constitute a single performance obligation which is satisfied over time and qualifies as a series of distinct service periods.

Trustmark receives a fixed service charge amount as consideration monthly for services rendered. The service charge amount varies based on the type of deposit account. Some of the service charge revenue is subject to refund provisions, which is variable consideration under the guidelines of FASB ASC Topic 606. Trustmark has elected the ‘as-invoiced’ practical expedient permitted under FASB ASC Topic 606 for recognition of service charge revenue. Therefore, revenue is recognized at the time and in the amount the customer is charged. The service charge revenue is presented net of refunded amounts on Trustmark’s consolidated statements of income.

Services related to non-sufficient funds, overdrafts, excess account activity, stop payments, dormant accounts, etc. are considered optional purchases for a deposit contract because there is no performance obligation for Trustmark until the service is requested by the customer or the occurrence of a triggering event. Fees for these services are fixed amounts and are charged to the customer when the service is performed. Revenue is recognized at the time the customer is charged.

Bank Card and Other Fees

Revenue from contracts with customers in bank card and other fees includes income related to interchange fees and various other contracts which primarily consists of contracts with a single performance obligation that is satisfied at a point in time. Trustmark receives a fixed consideration amount once the performance obligation is completed for these contracts. Trustmark reports revenue from these contracts net of amounts refunded or due to a third party.

As both a debit and credit card issuer, Trustmark receives an interchange fee for every card transaction completed by its customers with a merchant. Trustmark receives two types of interchange fees: point-of-sale transactions in which the customer must enter the PIN associated with the card to complete the transaction (a debit card transaction), and signature transactions in which the signature of the customer is required to complete the transaction (a credit card transaction).

Trustmark, as the card issuing or settlement bank, has a contract (implied based on customary business practices) with the payment network in which Trustmark has a single continuous service obligation to make funds available for settlement of the card transaction. Trustmark’s service obligation is satisfied over time and qualifies as a series of distinct service periods. Trustmark receives interchange fees as consideration for services rendered in the amount established by the respective payment network. The interchange fees are established by the payment network based on the type of transaction and is posted on their website. Trustmark receives and records interchange fee revenue from the payment networks daily net of all fees and amounts due to the payment network.

Other Income

Revenue from contracts with customers in other income includes income related to cash management services and other contracts with a single performance obligation that is satisfied at a point in time. Trustmark receives a fixed consideration amount once the performance obligation is completed for these contracts. Trustmark reports revenue from these contracts net of amounts refunded or due to a third party.

Trustmark provides cash management services through the delivery of various products and services offered to its business and municipal customers including various departments of state, city and local governments, universities and other non-profit entities. Similar to the deposit account contracts, the cash management contracts primarily represent contracts with customers with no fixed duration and can be terminated or modified by either party at any time without compensation to the other party. Therefore, cash management contracts are generally considered to renew day-to-day if not minute-to-minute.

Cash management contracts have a single continuous or stand-ready service obligation whereby Trustmark makes a specific service or group of services available for use by the customer as and when the customer chooses. The specific services provided vary based on the type of account or product. These services are not individually distinct, but are distinct as a group, and therefore, constitute a single performance obligation which is satisfied over time and qualifies as a series of distinct service periods.

Trustmark receives a set service charge or maintenance fee amount as consideration monthly for services rendered. However, some of the fees are based on the number of transactions that occur (i.e., flat fee for a set number of transactions per month then an additional charge for each transaction after that) or the average daily account balance maintained by the customer during the month and a small amount of the cash management fee revenue is subject to refund provisions. These fees represent variable consideration under the guidelines of FASB ASC Topic 606. Trustmark has elected the ‘as-invoiced’ practical expedient permitted under FASB ASC Topic 606 for recognition of cash management fee revenue. The cash management revenue is presented net of any refunded amounts on Trustmark’s consolidated statements of income.

Trustmark’s merchant services provider contracts directly with Trustmark business customers and provides Trustmark’s merchant customers card processing equipment and transaction processing services. Trustmark’s contract with the merchant services provider has a single-continuous service obligation to provide customer referrals for potential new accounts which is satisfied over time and qualifies as a series of distinct service periods. Trustmark receives a flat fee for each new account established and a percentage of the residual income related to transactions processed for Trustmark’s merchant customers each month as provided in the contract. Under the guidelines of FASB ASC Topic 606, the fee received for each new account and the profit sharing represent variable consideration. Revenue from merchant card services contracts is recognized monthly using a time-elapsed measure of progress. Trustmark has elected the ‘as-invoiced’ practical expedient permitted under FASB ASC Topic 606 for recognition of the merchant card services revenue.

Other Real Estate

Trustmark records a gain or loss from the sale of other real estate when control of the property transfers to the buyer. Trustmark records the gain or loss from the sale of other real estate in noninterest expense as other expense. Other real estate sales for the year ended December 31, 2023 resulted in a net loss of $145 thousand compared to a net loss of $1.0 million for the year ended December 31, 2022 and a net loss of $1.9 million for the year ended December 31, 2021.

In general, purchases of Trustmark’s other real estate property are not financed by Trustmark. Financing the purchase of other real estate is evaluated based upon the same lending policies and procedures as all other types of loans. Under FASB ASC Subtopic 610-20, “Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets,” when Trustmark finances the sale of its other real estate to a buyer, Trustmark is required to assess whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these two criteria are met, Trustmark derecognizes the other real estate asset and records a gain or loss on the sale once control of the property is transferred to the buyer.

Wealth Management Segment

Trust Management

There are five categories of revenue included in trust management: personal trust and investments, retirement plan services, institutional custody, corporate trust and other. Each of these categories includes multiple types of contracts, service obligations and fee income. However, the majority of these contracts include a single service obligation that is satisfied over time, the customer is charged in arrears for services rendered and revenue is recognized when payment is received. In general, the time period between when the service obligation is completed and when payment from the customer is received is less than 30 days. Revenue from trust management contracts is primarily related to monthly service periods and based on the prior month-end’s market value. Some trust management revenue is mandated by a court order, while other revenue consists of flat fees. Trust management revenue based on an account’s market value represents variable consideration under the guidelines of FASB ASC Topic 606. Trustmark has elected the ‘as-invoiced’ practical expedient allowed under FASB ASC Topic 606 to account for the trust management revenue.

Assets under administration held by Trustmark in a fiduciary or agency capacity for customers are not included in Trustmark’s consolidated balance sheets.

Investment Services

Investment services includes both brokerage and annuity income. Trustmark has a contract with a third-party investment services company which contains a single continuous service obligation, to provide broker-dealer and advisory services to customers on behalf of the third-party, which is satisfied over time and qualifies as a series of distinct service periods. Trustmark serves as the agent between the third-party investment services company, the principle, and the customer. In accordance with the contract, Trustmark receives a monthly payment from the investment services company for commissions and advisory fees (asset management fees) earned on transactions completed in the prior month net of all charges and fees due to the investment services company. Trustmark recognizes revenue from the investment services company, net of the revenue sharing expense due to the investment services company, when the payments are received. Commissions vary from month-to-month based on the specific products and transactions completed. The advisory fees vary based on the average daily balance of the managed assets for the period. The commissions and advisory fees represent variable consideration under FASB ASC Topic 606. Trustmark has elected the ‘as-invoiced’ practical expedient allowed under FASB ASC Topic 606 to recognize revenue from the investment services company.

Insurance Segment

Fisher Brown Bottrell Insurance, Inc. (FBBI), a wholly-owned subsidiary of Trustmark National Bank (TNB), operates as an insurance broker representing the policyholder and has no allegiance with any one insurance provider. FBBI serves as the agent between the insurance provider (either insurance carrier or broker), the principal, and the policy holder, the customer. FBBI has four general categories of insurance contracts: commercial, commercial installments, personal and employee benefits. FBBI’s insurance contracts contain a single performance obligation, policy placement, which is satisfied at a point in time. FBBI’s performance obligation is satisfied as of the policy effective date.

In addition to policy placement, FBBI provides various other periodic services to the policyholders for which no additional fee is charged. These additional services are not considered material to the overall contract. Trustmark has elected the immaterial promises practical expedient allowed under FASB ASC Topic 606, which allows Trustmark to not assess whether promised services are performance obligations if the promised services are immaterial in the context of the contract. Therefore, the immaterial additional services offered to policyholders are not considered a performance obligation and no amount of the contract transaction price is allocated to these services.

In general, the transaction price for the insurance contracts is an established commission amount agreed upon by FBBI and the insurance provider. The commission amount varies based on the insurance provider and the type of policy. There are a small number of insurance contracts which FBBI does not receive a commission but charges a fee directly to the policyholder.

Most of the commissions from insurance contracts are subject to clawback provisions which require FBBI to refund a prorated amount of the commissions received as a result of policy cancellations or lapses. Commissions subject to clawback provisions are considered variable consideration under FASB ASC Topic 606. Trustmark believes the expected value method of estimating the commissions subject to clawback provisions would best predict the amount of commissions FBBI will be entitled to because of the large number of insurance contracts with similar characteristics and the number of possible outcomes. FBBI calculates a separate weighted-average percentage (returned commissions percentage) based on actual cancellations over the previous three years for commercial lines, bonds, and personal lines. FBBI applies the respective returned commissions percentage to the commission revenue earned related to insurance contracts within these three lines each month to calculate the estimated returned commissions amount, which represents the variable consideration subject to variable constraint. Revenue from insurance contracts is reported net of the variable consideration subject to variable constraint. FBBI performs an analysis of the returned commissions reserve quarterly and adjusts the reserve balance based on all available information including actual cancellations and the remaining term of the contract. The returned commission percentage is updated annually.

Insurance Producers at FBBI earn commission as compensation for each policy they are responsible for placing. FBBI utilizes a ‘pay when paid’ system. Under the ‘pay when paid’ system, Producers receive the commissions for which they are entitled at the end of the month following the month in which FBBI receives payment from the insurance provider or customer. Under FASB ASC Subtopic 340-40, “Other Assets and Deferred Costs: Contracts with Customers,” the commission paid to the Producers is an incremental cost of obtaining a contract, which should be capitalized and amortized in a manner consistent with the pattern of transfer of the service related to the contract acquisition asset. Insurance contracts have a term of one year or less; therefore, Trustmark has elected the cost of obtaining a contract practical expedient allowed under FASB ASC Subtopic 340-40, which allows FBBI to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the contract asset that FBBI otherwise would have recognized is one year or less. Commission expense is recorded as noninterest expense in salaries and employee benefits when paid to the Producers.

Commercial Insurance

Revenue from FBBI’s commercial insurance contracts (both agency billed and direct billed) consists of a set commission amount, which is subject to clawback provisions. Revenue from commercial installment insurance contracts consists of a set commission amount, which is not subject to clawback provisions. An estimated commission amount is entered in the agency management system when a commercial insurance contract is placed. FBBI records a top line receivable based on the estimated commission amount entered in the system each month, along with a corresponding amount recognized as revenue, and then adjusts the estimated receivable when the commissions are received from the insurance provider or customer.

Personal Insurance

Revenue from FBBI’s personal insurance contracts consists of a set commission amount, which is subject to clawback provisions, and is recognized when payment is received (generally 30-60 days after the policy effective date). Personal insurance contracts have a term of one year; therefore, recognizing the revenue from these contracts when payment is received is not materially different than recognizing the revenue at the policy effective date for any given period.

Employee Benefits Insurance

Revenue from FBBI’s employee benefits insurance contracts consists of a variable commission amount, which is not subject to clawback provisions, and is recognized when payment is received, typically on a monthly basis. Employee benefits insurance contracts have a set commission rate, but can vary from period to period based on changes in the number of employees covered by the policy (i.e., new hires and terminations). FBBI generally receives twelve monthly commission payments for these contracts with the initial payment being received approximately 60-90 days after the policy effective date. Under the guidelines of FASB ASC Topic 606, commissions from employee benefits insurance contracts represent fixed consideration because at contract inception (policy effective date) there is a set commission rate times a known number of covered employees. Changes in the number of covered employees are not known, nor can they be predicted, at contract inception. An increase or decrease in the number of covered employees after the policy effective date is considered a contract modification resulting from a change in scope and transaction price under FASB ASC Topic 606. This modification is treated as part of the existing contract because it does not add a distinct service. Employee benefits insurance contracts have a term of one year; therefore, recognizing the revenue from these contracts when payment is received is not materially different than recognizing the revenue at the policy effective date or the contract modification date for any given period.

Contingency Commission Insurance

In addition to the insurance contracts discussed above, FBBI has contracts with various insurance providers for which it receives contingency income based on volume of business and claims experience. FBBI is the principal and the insurance provider is the customer for these contingency commission insurance contracts. The contingency commission contracts have a single continuous or stand-ready service obligation whereby FBBI places policies with policyholders when acceptable to the insurance provider, which is satisfied over time. The contract term for these contingency commission contracts is one year. Revenue is recognized from the contingency commission contracts monthly using a time-elapsed measure of progress. FBBI accrues throughout the current year the amount of contingency commission income it expects to receive in the following year adjusted for a degree of uncertainty. FBBI updates a detail by insurance provider with the contingency commission income received, which is then compared to the total amount that was expected to be received. If actual receipts are higher or lower than the amount accrued in the prior year, the monthly accrual for the current year is adjusted accordingly.

Under the guidelines of FASB ASC Topic 606, revenue from contingency commission insurance contracts represents variable consideration and should be estimated using one of the two allowable methods subject to the variable consideration constraint. FBBI believes the most likely amount method to be the most appropriate method for estimating the variable consideration as there are only a few possible outcomes for each contract.

Derivative Financial Instruments

Trustmark maintains an overall interest rate risk management strategy that incorporates the use of derivative instruments to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. Trustmark’s interest rate risk management strategy involves modifying the repricing characteristics of certain assets and liabilities so that changes in interest rates do not adversely affect the net interest margin and cash flows. Under the guidelines of FASB ASC Topic 815, “Derivatives and Hedging,” all derivative instruments are required to be recognized as either assets or liabilities and carried at fair value on the balance sheet. The fair value of derivative positions outstanding is included in other assets and/or other liabilities in the accompanying consolidated balance sheets and in the net change in these financial statement line items in the accompanying consolidated statements of cash flows as well as included in noninterest income in the accompanying consolidated statements of income and other comprehensive income (loss), net

of tax in the accompanying consolidated statements of comprehensive income. Trustmark’s interest rate derivative instruments are subject to master netting agreements, and therefore, eligible for offsetting in the consolidated balance sheets. Trustmark has elected to not offset any derivative instruments in its consolidated balance sheets.

Derivatives Designated as Hedging Instruments

FASB ASC Topic 815, Derivatives and Hedging (ASC 815), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments.

Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge.

When entering into a hedge transaction, Trustmark formally documents the relationship between the hedging instrument and the hedged item, as well as the risk management objective and strategy for undertaking the hedge transaction, which includes designating the derivative instrument as a fair value or cash flow hedge to a specific asset or liability on the balance sheet or to specific forecasted transactions and the risk being hedged, along with a formal assessment at the inception of the hedge as to the effectiveness of the derivative instrument in offsetting changes in fair values or cash flows of the hedged item. Trustmark continues to assess hedge effectiveness on an ongoing basis using either a qualitative or a quantitative assessment (regression analysis).

As required by ASC 815, Trustmark records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether Trustmark has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. For cash flow hedges, changes in the fair value of the derivative instrument are recorded in accumulated other comprehensive income (loss) and subsequently reclassified to net income in the same period that the hedged transaction impacts net income. Upon discontinuation of hedge accounting for cash flow hedges, any amounts in accumulated other comprehensive income (loss) related to that relationship affects earnings at the same time and in the same manner in which the hedged transaction affects earnings. If it becomes probable that the forecasted transaction will not occur, any related amounts in accumulated other comprehensive income (loss) are reclassified to earnings immediately.

Derivatives Not Designated as Hedging Instruments

As part of Trustmark’s risk management strategy in the mortgage banking area, derivative instruments such as forward sales contracts are utilized. Trustmark’s obligations under forward contracts consist of commitments to deliver mortgage loans, originated and/or purchased, in the secondary market at a future date. Changes in the fair value of these derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by changes in the fair value of LHFS. See Note 1 – Significant Accounting Policies, “Loans Held for Sale (LHFS)” for information regarding the fair value option election.

Trustmark also utilizes derivative instruments such as interest rate lock commitments in its mortgage banking area. Rate lock commitments are residential mortgage loan commitments with customers, which guarantee a specified interest rate for a specified time period. Changes in the fair value of these derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by the changes in the fair value of forward sales contracts.

Trustmark utilizes a portfolio of exchange-traded derivative instruments, such as Treasury note futures contracts and option contracts, to achieve a fair value return that economically hedges changes in the fair value of the MSR attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting. These exchange-traded derivative instruments are accounted for at fair value with changes in the fair value recorded as noninterest income in mortgage banking, net and are offset by changes in the fair value of the MSR. The MSR fair value represents the present value of future cash flows, which among other things includes decay and the effect of changes in interest rates. Ineffectiveness of hedging the MSR fair value is measured by comparing the change in the fair value of the hedge instruments to the change in the fair value of the MSR asset attributable to changes in interest rates and other market driven changes in valuation inputs and assumptions.

Trustmark offers certain derivatives products directly to qualified commercial lending clients seeking to manage their interest rate risk. Trustmark economically hedges interest rate swap transactions executed with commercial lending clients by entering into offsetting interest rate swap transactions with institutional derivatives market participants. Derivative transactions executed as part of this program are not designated as qualifying hedging relationships and are, therefore, carried at fair value with the change in fair value recorded as noninterest income in bank card and other fees. Because these derivatives have mirror-image contractual terms, in addition to collateral provisions which mitigate the impact of non-performance risk, the changes in fair value are expected to substantially offset. The offsetting interest rate swap transactions are either cleared through the Chicago Mercantile Exchange for clearable transactions or booked directly with institutional derivatives market participants for non-clearable transactions. The Chicago Mercantile Exchange rules legally characterize variation margin collateral payments made or received for centrally cleared interest rate swaps as settlements rather than collateral. As a result, centrally cleared interest rate swaps included in other assets and other liabilities are presented on a net basis in the accompanying consolidated balance sheets.

Income Taxes

Trustmark accounts for uncertain tax positions in accordance with FASB ASC Topic 740, “Income Taxes,” which clarifies the accounting and disclosure for uncertainty in tax positions. Under the guidance of FASB ASC Topic 740, Trustmark accounts for deferred income taxes using the liability method. Deferred tax assets and liabilities are based on temporary differences between the financial statement carrying amounts and the tax basis of Trustmark’s assets and liabilities. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be realized or settled and are presented net in the accompanying consolidated balance sheets in other assets.

Stock-Based Compensation

Trustmark accounts for the stock and incentive compensation under the provisions of FASB ASC Topic 718, “Compensation – Stock Compensation.” Under this accounting guidance, fair value is established as the measurement objective in accounting for stock awards and requires the application of a fair value based measurement method in accounting for compensation cost, which is recognized over the requisite service period. Trustmark has elected to account for forfeitures of stock awards as they occur.

Statements of Cash Flows

For purposes of reporting cash flows, cash and cash equivalents include cash on hand and amounts due from banks. The following table reflects specific transaction amounts for the periods presented ($ in thousands):

Finance right-of-use assets resulting from lease liabilities		—		—		92
Operating right-of-use assets resulting from lease liabilities		7,303		6,912		9,666

Per Share Data

Trustmark accounts for per share data in accordance with FASB ASC Topic 260, “Earnings Per Share,” which provides that unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share (EPS) pursuant to the two-class method. Trustmark has determined that its outstanding unvested stock awards are not participating securities. Based on this determination, no change has been made to Trustmark’s current computation for basic and diluted EPS.

Basic EPS is computed by dividing net income by the weighted-average shares of common stock outstanding. Diluted EPS is computed by dividing net income by the weighted-average shares of common stock outstanding, adjusted for the effect of potentially dilutive stock awards outstanding during the period.

The following table reflects weighted-average shares used to calculate basic and diluted EPS for the periods presented (in thousands):

Fair Value Measurements

FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and requires certain disclosures about fair value measurements. The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. Depending on the nature of the asset or liability, Trustmark uses various valuation techniques and assumptions when estimating fair value. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. FASB ASC Topic 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

Level 1 Inputs – Valuation is based upon quoted prices (unadjusted) in active markets for identical assets or liabilities that Trustmark has the ability to access at the measurement date.

Level 2 Inputs – Valuation is based upon quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability such as interest rates, yield curves, volatilities and default rates and inputs that are derived principally from or corroborated by observable market data.

Level 3 Inputs – Unobservable inputs reflecting the reporting entity’s own determination about the assumptions that market participants would use in pricing the asset or liability based on the best information available.

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the fair value measurement in its entirety is classified is based on the lowest level input that is significant to the fair value measurement in its entirety. Trustmark’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer.

Accounting Policies Recently Adopted

Except for the changes detailed below, Trustmark has consistently applied its accounting policies to all periods presented in the accompanying consolidated financial statements.

ASU 2022-02, “Financial Instruments-Credit Losses (Topic 326): Trouble Debt Restructurings and Vintage Disclosures.” Issued in March 2022, ASU 2022-02 seeks to improve the decision usefulness of information provided to investors concerning certain loan refinancings, restructurings and write-offs. In regard to troubled debt restructurings (TDRs) by creditors, investors and preparers observed that the additional designation of a loan modification as a TDR and the related accounting are unnecessarily complex and no longer provide decision-useful information. The amendments of ASU 2022-02 eliminate the accounting guidance for TDRs by creditors in FASB ASC Subtopic 310-40, “Receivables-Troubled Debt Restructurings by Creditors,” as it is no longer meaningful due to the implementation of FASB ASC Topic 326, which requires an entity to consider lifetime expected credit losses on loans when establishing an allowance for credit losses. Therefore, most losses that would have been realized for a TDR under FASB ASC Subtopic 310-40 are now captured by the accounting required under FASB ASC Topic 326. The amendments of ASU 2022-02 also enhanced disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Stakeholders also noted inconsistency in the requirement for a public business entity (PBE) to disclose gross write-offs and gross recoveries by class of financing receivable and major security type in certain vintage disclosures. Financial statement users expressed that, in addition to the existing vintage disclosures in FASB ASC Topic 326, information about gross write-offs by year of origination

would be helpful in understanding credit quality changes in an entity’s loan portfolio and underwriting performance. For PBEs, the amendments of ASU 2022-02 require that an entity disclose current period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of FASB ASC Subtopic 326-20, “Financial Instruments-Credit Losses-Measured at Amortized Cost.” For write-offs associated with origination dates that are more than five annual periods before the reporting period, an entity may present aggregate amounts in the current period for financing receivables and net investment in leases. The amendments of ASU 2022-02 were effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2022 for entities that have already adopted the amendments of ASU 2016-13, such as Trustmark. Trustmark adopted the amendments of ASU 2022-02 effective January 1, 2023. The amendments of ASU 2022-02 include only changes to certain financial statement disclosures; and, therefore, adoption of ASU 2022-02 did not have a material impact on Trustmark’s consolidated financial statements or results of operations. The enhanced disclosures required by ASU 2022-02 are presented in Note 4 - LHFI and ACL, LHFI of this report.

ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” Issued in November 2023, ASU 2023-07 is intended to improve disclosures about a public entity’s reportable segments and address requests from investors and other allocators of capital for additional, more detailed information about a reportable segment’s expenses. The amendments of ASU 2023-07 require a public entity to disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within each reported measure of segment profit or loss, and an amount for other segment items by reportable segment and a description of its composition. The other segment items category is the difference between segment revenue less the significant expenses disclosed and each reported measure of segment profit or loss. ASU 2023-07 also requires a public entity to provide all annual disclosures about a reportable segment’s profit or loss and assets currently required under FASB ASC Topic 280 in interim periods. The amendments of ASU 2023-07 clarify that if the CODM uses more than one measure of a segment's profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures of segment profit. However, at least one of the reported segment profit or loss measures (or the single reported measure if only one is disclosed) should be the measure that is most consistent with the measurement principles used in measuring the corresponding amounts in the public entity's consolidated financial statements. ASU 2023-07 requires a public entity to disclose the title and position of the CODM, together with an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. In addition, ASU 2023-07 requires that a public entity with a single reportable segment provide all the disclosures required by the amendments of ASU 2023-07 and all existing segment disclosures in FASB ASC Topic 280. The amendments of ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments in ASU 2023-07 should be applied retrospectively to all periods presented on the financial statements. Upon implementation, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. Trustmark has adopted the amendments of ASU 2023-07 related to annual disclosure requirements effective January 1, 2024, and will present any newly required annual disclosures in its Annual Report of Form 10-K for the year ending December 31, 2024. Trustmark intends to adopt the amendments of ASU 2023-07 related to interim disclosure requirements effective January 1, 2025, and will present any newly required interim disclosures beginning with its Quarterly Report on Form 10-Q for the period ending March 31, 2025. Adoption of ASU 2023-07 is not expected to have a material impact to Trustmark’s consolidated financial statements or results of operations.

Pending Accounting Pronouncements

ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” Issued in December 2023, ASU 2023-09 is intended to improve the disclosures for income taxes to address requests from investors, lenders, creditors and other allocators of capital (collectively, "investors") that use the financial statements to make capital allocation decisions. During the FASB's 2021 agenda consultation process and other stakeholder outreach, investors highlighted that the current system of income tax disclosures does not provide enough information to understand the tax provision for an entity that operates in multiple jurisdictions. Investors currently rely on the rate reconciliation table and other disclosures, including total income taxes paid in the statement of cash flows, to evaluate income tax risks and opportunities. The amendments in ASU 2023-09 will require consistent categories and greater disaggregation of information in the rate reconciliation disclosure as well as disclosure of income taxes paid disaggregated by jurisdiction. The amendments of ASU 2023-09 are effective for annual periods beginning after December 15, 2024, and early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. Trustmark intends to adopt the amendments of ASU 2023-09 effective January 1, 2025, and will include the required disclosures in its Annual Report on Form 10-K for the year ending December 31, 2025.
