Accounting Policies [Abstract] |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations S&T Bancorp, Inc., or S&T, was incorporated on March 17, 1983 under the laws of the Commonwealth of Pennsylvania as a bank holding company and has four active direct wholly owned subsidiaries, S&T Bank, 9th Street Holdings, Inc., STBA Capital Trust I and DNB Capital Trust II, and owns a 50 percent interest in Commonwealth Trust Credit Life Insurance Company, or CTCLIC. We are presently engaged in non-banking activities through the following six entities: 9th Street Holdings, Inc.; S&T Bancholdings, Inc.; CTCLIC; S&T Insurance Group, LLC; Stewart Capital Advisors, LLC; and DN Acquisition Company, Inc. Our investment holding companies are 9th Street Holdings, Inc. and S&T Bancholdings, Inc. CTCLIC, which is a joint venture with another financial institution, acts as a reinsurer of credit life, accident and health insurance policies sold by S&T Bank and the other institution. S&T Insurance Group, LLC, through its subsidiaries, offers a variety of insurance products. Stewart Capital Advisors, LLC is a registered investment advisor that manages private investment accounts for individuals and institutions. DN Acquisition Company, Inc. was acquired with the DNB merger and was incorporated for the purpose of acquiring and holding OREO acquired through foreclosure or deed in-lieu-of foreclosure, as well as Bank-occupied real estate. Accounting Policies Our consolidated financial statements have been prepared in accordance with generally accepted accounting principles, or GAAP. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as well as disclosures of contingent assets and liabilities as of the dates of the balance sheets and revenues and expenses for the periods then ended. Actual results could differ from those estimates. Our significant accounting policies are described below. Principles of Consolidation The consolidated financial statements include the accounts of S&T and its wholly owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. Investments of 20 percent to 50 percent of the outstanding common stock of investees are accounted for using the equity method of accounting. Reclassification Amounts in prior years' financial statements and footnotes are reclassified whenever necessary to conform to the current period presentation. Reclassifications had no effect on our results of operations or financial condition. Business Combinations We account for business combinations using the acquisition method of accounting. All identifiable assets acquired, liabilities assumed and any non-controlling interest in the acquiree are recognized and measured as of the acquisition date at fair value. We record goodwill for the excess of the purchase price over the fair value of net assets acquired. Results of operations of the acquired entities are included in the Consolidated Statement of Net Income from the date of acquisition. Acquired loans are recorded at fair value on the date of acquisition with no carryover of the related ACL. Determining the fair value of acquired loans involves estimating the principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. In estimating the fair value of our acquired loans, we consider a number of factors including loss rates, internal risk rating, delinquency status, loan type, loan term, prepayment rates, recovery periods and the current interest rate environment. The premium or discount estimated through the loan fair value calculation is recognized into interest income on a level yield basis over the remaining life of the loans. Acquired loans, including those acquired in a business combination, are evaluated to determine if they have experienced more-than-insignificant deterioration in credit quality since origination. When the condition exists, these loans are referred to as purchased credit deteriorated, or PCD. An allowance is recognized for a PCD loan by adding it to the purchase price or fair value in a business combination. There is no provision for credit losses, or PCL, recognized upon acquisition of a PCD loan since the initial allowance is established through the purchase accounting. After initial recognition, the accounting for a PCD loan follows the credit loss model that applies to that type of asset. Purchased financial loans that do not have a more-than-significant deterioration in credit quality since origination are accounted for in a manner consistent with originated loans. An ACL is recorded with a corresponding charge to PCL. Subsequent to the acquisition date, the methods utilized to estimate the required ACL for these loans is similar to the method used for originated loans. Fair Value Measurements We use fair value measurements when recording and disclosing certain financial assets and liabilities. Available-for-sale debt securities, equity securities, trading securities held in a deferred compensation plan and derivative financial instruments are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record other assets at fair value on a nonrecurring basis, such as loans held for sale, individually assessed loans, other real estate owned, or OREO, and other repossessed assets, mortgage servicing rights, or MSRs, and certain other assets. Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities; it is not a forced transaction. In determining fair value, we use various valuation approaches, including market, income and cost approaches. The fair value standard establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing an asset or liability, which are developed based on market data we have obtained from independent sources. Unobservable inputs reflect our estimates of assumptions that market participants would use in pricing an asset or liability, which are developed based on the best information available in the circumstances. The fair value hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The fair value hierarchy is broken down into three levels based on the reliability of inputs as follows: Level 1: valuation is based upon unadjusted quoted market prices for identical instruments traded in active markets. Level 2: valuation is based upon quoted market prices for similar instruments traded in active markets, quoted market prices for identical or similar instruments traded in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by market data. Level 3: valuation is derived from other valuation methodologies, including discounted cash flow models and similar techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in determining fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our policy is to recognize transfers between any of the fair value hierarchy levels at the end of the reporting period in which the transfer occurred. The following are descriptions of the valuation methodologies that we use for financial instruments recorded at fair value on either a recurring or nonrecurring basis. Recurring Basis Available-for-Sale Debt Securities We obtain fair values for debt securities from a third-party pricing service which utilizes several sources for valuing fixed-income securities. We validate prices received from our pricing service through comparison to a secondary pricing service and broker quotes. We review the methodologies of the pricing services which provide us with a sufficient understanding of the valuation models, assumptions, inputs and pricing to reasonably measure the fair value of our debt securities. The fair value of U.S. treasury securities are based on quoted market prices in active markets and are classified as Level 1. The market valuation sources for other debt securities include observable inputs rather than significant unobservable inputs and are classified as Level 2. The service provider utilizes pricing models that vary by asset class and include available trade, bid and other market information. Generally, the methodologies include broker quotes, proprietary models and extensive quality control programs. Equity Securities Marketable equity securities with quoted prices in active markets for identical assets are classified as Level 1. Marketable equity securities in markets that are not active are classified as Level 2. Securities Held in a Deferred Compensation Plan Securities Held in a Deferred Compensation Plan are reported at fair value with the gains and losses included in other noninterest income in our Consolidated Statements of Net Income. These assets are held in a deferred compensation plan and are invested in readily quoted mutual funds. Accordingly, these assets are classified as Level 1. Deferred compensation plan assets are reported in other assets in the Consolidated Balance Sheets. Derivative Financial Instruments We use derivative instruments, including interest rate swaps that qualify as cash flow hedges, interest rate swaps for commercial loans with our customers, interest rate lock commitments and forward commitments related to the sale of mortgage loans in the secondary market. We calculate the fair value for derivatives using accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. Each valuation considers the contractual terms of the derivative, including the period to maturity, and uses observable market-based inputs, such as interest rate curves and implied volatilities. We incorporate credit valuation adjustments into the valuation models to appropriately reflect both our own nonperformance risk and the respective counterparties’ nonperformance risk in calculating fair value measurements. We consider the impact of master netting agreements and collateral postings with our counterparties to determine the credit valuation adjustment. Interest rate swaps are classified as Level 2. Interest rate lock commitments and forward commitments related to mortgage loans are classified as Level 3 due to significant unobservable inputs. Nonrecurring Basis Loans Held for Sale Loans held for sale consist of 1-4 family residential loans originated for sale in the secondary market and, from time to time, certain loans transferred from the loan portfolio to loans held for sale, all of which are carried at the lower of cost or fair value. The fair value of 1-4 family residential loans, when marked to fair value, is based on the principal or most advantageous market currently offered for similar loans using observable market data. Loans held for sale marked to fair value are classified as Level 2 if the fair value is determined using a sales or market approach and Level 3 if the fair value is determined using an income approach. Loans Individually Evaluated Loans that are individually evaluated to determine whether a specific allocation of ACL is needed are reported at the lower of amortized cost or fair value. Fair value is determined using either the present value of expected future cash flows discounted at the loan's original effective interest rate, the loan’s observable market price or the fair value of the collateral less estimated selling costs when the loan is collateral dependent and we expect to liquidate the collateral. However, if repayment is expected to come from the operation of the collateral, rather than liquidation, then we do not consider estimated selling costs in determining the fair value of the collateral. Collateral values are generally based upon appraisals by approved, independent state certified appraisers. Appraisals may be discounted based on our historical knowledge, changes in market conditions from the time of appraisal or our knowledge of the borrower and the borrower’s business. If the fair value of loans individually evaluated is determined based on an independent market based appraisal less estimated costs to sell, it is classified as Level 2. If the fair value of loans individually evaluated is determined using an internal valuation, it is classified as Level 3. OREO and Other Repossessed Assets OREO and other repossessed assets obtained in partial or total satisfaction of a loan are recorded at fair value less cost to sell. Fair value, when recorded, is generally based upon appraisals by approved, independent state certified appraisers. Appraisals on OREO may be discounted based on our historical knowledge, changes in market conditions from the time of appraisal or other information available to us. If the fair value for OREO is determined based on an independent market-based appraisal less estimated costs to sell or an executed sales agreement, it is classified as Level 2. If the fair value for OREO is determined using an internal valuation, it is classified as Level 3. Mortgage Servicing Rights MSRs are reported using the amortization method and are evaluated for impairment quarterly by comparing the carrying value to the fair value of the MSRs. The fair value of MSRs is determined by calculating the present value of estimated future net servicing cash flows, considering expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors, which are determined based on current market conditions. The expected rate of mortgage loan prepayments is the most significant factor driving the value of MSRs. MSRs are considered impaired if the carrying value exceeds fair value. The valuation model includes significant unobservable inputs; therefore, MSRs are classified as Level 3 when marked to fair value. Financial Instruments Fair value accounting guidance requires disclosure of the fair value of all of an entity’s assets and liabilities that are considered financial instruments. The majority of our assets and liabilities are considered financial instruments. Many of these instruments lack an available trading market as characterized by a willing buyer and willing seller engaged in an exchange transaction. Also, it is our general practice and intent to hold our financial instruments to maturity and to not engage in trading or sales activities with respect to such financial instruments. For fair value disclosure purposes, we substantially utilize the fair value measurement criteria as required and explained above. In cases where quoted fair values are not available, we use present value methods to determine the fair value of our financial instruments. Cash and Cash Equivalents The carrying amounts reported in the Consolidated Balance Sheets for cash and due from banks, including interest-bearing deposits approximate fair value. Loans Our methodology to fair value loans includes an exit price notion. The fair value of loans is estimated using discounted cash flow analyses that utilize interest rates currently being offered for similar loans and adjusted for liquidity and credit risk. The valuation models include significant unobservable inputs; therefore, loans are classified as Level 3. The carrying amount of interest receivable approximates fair value. Federal Home Loan Bank, or FHLB, and Other Restricted Stock It is not practical to determine the fair value of our FHLB and other restricted stock due to the restrictions placed on the transferability of these stocks; it is presented at carrying value. Collateral Receivable Collateral receivable is cash that is made available to counterparties as collateral for our interest rate swaps. The carrying amount included in other assets on our Consolidated Balance Sheets approximates fair value. Deposits The fair values disclosed for deposits without defined maturities (e.g., noninterest and interest-bearing demand, money market and savings accounts) are by definition equal to the amounts payable on demand. Deposits without defined maturities are classified as Level 1. The carrying amounts for variable rate, fixed-term time deposits approximate their fair values. Estimated fair values for fixed rate and other time deposits are based on discounted cash flow analysis using interest rates currently offered for time deposits with similar terms. Fixed rate and other time deposits are classified as Level 2. The carrying amount of accrued interest approximates fair value. Short-Term Borrowings The carrying amounts of securities sold under repurchase agreements, or REPOs, and other short-term borrowings approximate their fair values. Fair values are based on observable inputs in a secondary market; therefore, these are classified as Level 2. Long-Term Borrowings The fair values disclosed for fixed rate long-term borrowings are determined by discounting their contractual cash flows using current interest rates for long-term borrowings of similar remaining maturities. The carrying amounts of variable rate long-term borrowings approximate their fair values. Fair values are based on observable inputs in a secondary market; therefore, these are classified as Level 2. Junior Subordinated Debt Securities The interest rate on the variable rate junior subordinated debt securities is reset quarterly; therefore, the carrying values approximate their fair values. Fair values are based on observable inputs in a secondary market; therefore, these are classified as Level 2. Collateral Payable Collateral payable is cash that is received from counterparties as collateral for our interest rate swaps. The carrying amount included in other liabilities on our Consolidated Balance Sheets approximates fair value. Cash and Cash Equivalents We consider cash and due from banks, interest-bearing deposits with banks and federal funds sold as cash and cash equivalents. Securities We determine the appropriate classification of securities at the time of purchase. Debt securities are classified as available-for-sale with the intent to hold for an indefinite period of time, but may be sold in response to changes in interest rates, prepayment risk, liquidity needs or other factors. A determination will be made on whether a decline in the fair value below the amortized cost basis is due to credit-related factors or noncredit-related factors. Any impairment that is not credit-related is recognized in OCI, net of applicable taxes. Credit-related impairment is recognized as an ACL on the balance sheet with a corresponding adjustment to provision for credit losses in the Consolidated Statements of Net Income. Both the allowance and the adjustment to net income can be reversed if conditions change. Our policy for credit impairment within the available-for-sale debt securities portfolio is based upon a number of factors, including but not limited to, the financial condition of the underlying issuer, the ability of the issuer to meet contractual obligations, the likelihood of the security’s ability to recover any decline in its estimated fair value and whether management intends to sell the security or if it is more likely than not that management will be required to sell the investment security prior to the security’s recovery of any decline in its estimated fair value. Realized gains and losses on the sale of these securities are determined using the specific-identification method and are recorded within noninterest income in the Consolidated Statements of Net Income. Bond premiums are amortized to the call date, if any, and bond discounts are accreted to the maturity date, both on a level yield basis. Equity securities are measured at fair value with net unrealized gains and losses recognized in other noninterest income in the Consolidated Statements of Net Income. Loans Held for Sale Loans held for sale consist of 1-4 family residential loans originated for sale in the secondary market and, from time to time, certain loans transferred from the loan portfolio to loans held for sale, all of which are carried at the lower of cost or fair value. If a loan is transferred from the loan portfolio to the held for sale category, any write-down in the carrying amount of the loan at the date of transfer is recorded as a charge-off against the ACL. Subsequent declines in fair value are recognized as a charge to other noninterest income. When a loan is placed in the held for sale category, we stop amortizing the related deferred fees and costs. The remaining unamortized fees and costs are recognized as part of the cost basis of the loan at the time it is sold. Gains and losses on sales of mortgage loans held for sale are included in mortgage banking in noninterest income in the Consolidated Statements of Net Income. Loans Loans are reported at the principal amount outstanding net of unearned income. Unearned income consists of net deferred loan origination fees and costs and a discount or premium on acquired loans. Loan origination fees and direct loan origination costs are deferred and amortized as an adjustment of loan yield over the lives of the loans without consideration of anticipated prepayments. If a loan is paid off, the remaining unaccreted or unamortized net origination fees and costs are immediately recognized into income. Accretion of discounts and amortization of premiums on loans are included in interest income in the Consolidated Statements of Net Income. Interest is accrued and interest income is recognized on loans as earned. Closed-end installment loans, amortizing loans secured by real estate and any other loans with payments scheduled monthly are reported past due when the borrower is in arrears two or more monthly payments. Other multi-payment obligations with payments scheduled other than monthly are reported past due when one scheduled payment is due and unpaid for 30 days or more. Generally, consumer loans are charged off against the ACL upon the loan reaching 90 days past due. Commercial loans are charged off as management becomes aware of facts and circumstances that raise doubt as to the collectability of all or a portion of the principal and when we believe a confirmed loss exists. Nonaccrual Loans We stop accruing interest on a loan when the borrower’s payment is 90 days past due. Loans are also placed on nonaccrual status when we have doubt about the borrower’s ability to comply with contractual repayment terms, even if payment is not past due. When the interest accrual is discontinued, all unpaid accrued interest is reversed against interest income. As a general rule, a nonaccrual loan may be restored to accrual status when its principal and interest is paid current and the bank expects repayment of the remaining contractual principal and interest, or when the loan otherwise becomes well secured and in the process of collection. Allowance for Credit Losses The ACL is a valuation reserve established and maintained by charges against operating income and is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. Loans, or portions thereof, are charged off against the ACL when they are deemed uncollectible. The ACL is an estimate of expected credit losses, measured over the contractual life of a loan, that considers our historical loss experience, current conditions and forecasts of future economic conditions. Determination of an appropriate ACL is inherently subjective and may have significant changes from period to period. The methodology for determining the ACL has two main components: evaluation of expected credit losses for certain groups of homogeneous loans that share similar risk characteristics and evaluation of loans that do not share similar risk characteristics with other loans and are individually evaluated. The ACL for homogeneous loans is calculated using a life-time loss rate methodology with both a quantitative and a qualitative analysis that is applied on a quarterly basis. The ACL model is comprised of six distinct portfolio segments: 1) Commercial Construction, 2) Commercial Real Estate, or CRE, 3) Commercial and Industrial, or C&I, 4) Business Banking, 5) Consumer Real Estate and 6) Other Consumer. Each segment has a distinct set of risk characteristics monitored by management. We further evaluate the ACL at a disaggregated level which includes type of collateral and our internal risk rating system for the commercial and business banking segments and type of collateral, lien position and FICO score, for the consumer segments. Historical credit loss experience is the basis for the estimation of expected credit losses. Our quantitative model uses historic data back to the second quarter of 2009. We apply historical loss rates to pools of loans with similar risk characteristics. After consideration of the historic loss calculation, management applies qualitative adjustments to reflect the current conditions and reasonable and supportable forecasts not already reflected in the historical loss information at the balance sheet date. Our reasonable and supportable forecast is for a period of two years and is based on the unemployment forecast and management judgment. For periods beyond our two year reasonable and supportable forecast, we revert to historical loss rates utilizing a straight-line method over a one year reversion period. The qualitative adjustments for current conditions are based upon changes in lending policies and practices, experience and ability of lending staff, quality of the bank’s loan review system, value of underlying collateral, the existence of and changes in concentrations, other external factors and segment specific risks. These modified historical loss rates are multiplied by the outstanding principal balance of each loan to calculate a required reserve. The ACL for individual loans begins with the use of normal credit review procedures to identify whether a loan no longer shares similar risk characteristics with other pooled loans and therefore, should be individually assessed. We evaluate all commercial loans greater than $1.0 million that meet the following criteria: 1) when it is determined that foreclosure is probable, 2) substandard, doubtful and nonaccrual loans when repayment is expected to be provided substantially through the operation or sale of the collateral, 3) when it is determined by management that a loan does not share similar risk characteristics with other loans. Specific reserves are established based on the following three acceptable methods for measuring the ACL: 1) the present value of expected future cash flows discounted at the loan’s original effective interest rate; 2) the loan’s observable market price; or 3) the fair value of the collateral when the loan is collateral dependent. Our individual loan evaluations consist primarily of the fair value of collateral method because most of our loans are collateral dependent. Collateral values are discounted to consider disposition costs when appropriate. A specific reserve is established or a charge-off is taken if the fair value of the loan is less than the loan balance. Our ACL Committee meets quarterly to verify the overall appropriateness of the ACL. Additionally, on an annual basis, the ACL Committee meets to validate our ACL methodology. This validation includes reviewing the loan segmentation, critical model assumptions, forecast and the qualitative framework. As a result of this ongoing monitoring process, we may make changes to our ACL to be responsive to the economic environment. Bank Owned Life Insurance We have purchased life insurance policies on certain executive officers and employees. We receive the cash surrender value of each policy upon its termination or benefits are payable to us upon the death of the insured. Changes in net cash surrender value are recognized in other noninterest income in the Consolidated Statements of Net Income. Premises and Equipment Premises and equipment, including leasehold improvements, are stated at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred, while improvements that extend an asset’s useful life are capitalized and depreciated over the estimated remaining life of the asset. Depreciation expense is computed by the straight-line method for financial reporting purposes and accelerated methods for income tax purposes over the estimated useful lives of the particular assets. Depreciation expense is included in occupancy on the Consolidated Statements of Net Income. Long-lived assets are evaluated for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. No events or changes in circumstances occurred during the years ended December 31, 2023 and 2022. The estimated useful lives for the various asset categories are as follows:
1) Land and Land Improvements |  | Non-depreciating assets
2) Buildings |  | 25 years
3) Furniture and Fixtures |  | 5 years
4) Computer Equipment and Software |  | 5 years or term of license
5) Other Equipment |  | 5 years
6) Vehicles |  | 5 years
7) Leasehold Improvements |  | Lesser of estimated useful life of the asset (generally 15 years unless established otherwise) or the remaining term of the lease, including renewal options in the lease that are reasonably assured of exercise
Right-of-Use Assets and Lease Liabilities We determine if a contract is or contains a lease at inception. Leases are classified as either finance or operating leases. We recognize leases on our Consolidated Balance Sheets as right-of-use, or ROU, assets and related lease liabilities. Finance ROU assets are included in premises and equipment and related finance lease liabilities are included in long-term borrowings. Operating lease ROU assets are included in other assets and related operating lease liabilities are included in other liabilities. Our lease liability is calculated as the present value of the lease payments over the lease term discounted using our estimated incremental borrowing rate with similar terms at commencement date. Lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise those options. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term for operating leases. Interest and amortization expenses are recognized for finance leases over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet and the related lease expense is recognized on a straight-line basis over the lease term in occupancy on our Consolidated Statements of Net Income. Lease and amortization expenses are included in occupancy expense and interest on finance lease liabilities is included in borrowings interest expense in our Consolidated Statements of Net Income. Restricted Investment in Bank Stock FHLB stock is carried at cost and evaluated for impairment based on the ultimate recoverability of the par value. We hold FHLB stock because we are a member of the FHLB of Pittsburgh. The FHLB requires members to purchase and hold a specified level of FHLB stock based upon on the member's asset value, level of borrowings and participation in other programs offered. Stock in the FHLB is non-marketable and is redeemable at the discretion of the FHLB. Members do not purchase stock in the FHLB for the same reasons that traditional equity investors acquire stock in an investor-owned enterprise. Rather, members purchase stock to obtain access to the low-cost products and services offered by the FHLB. Unlike equity securities of traditional for-profit enterprises, the stock of the FHLB does not provide its holders with an opportunity for capital appreciation because, by regulation, FHLB stock can only be purchased, redeemed and transferred at par value. Both cash and stock dividends are reported as income in taxable investment securities in the Consolidated Statements of Net Income. FHLB stock is evaluated for impairment when events and circumstance indicate that impairment could exist. Goodwill and Other Intangible Assets As a result of acquisitions, we have recorded goodwill and identifiable intangible assets in our Consolidated Balance Sheets. Goodwill represents the excess of the purchase price over the fair value of net assets acquired. We have one reporting unit. The carrying value of goodwill is tested annually for impairment each October 1st or more frequently if events and circumstances indicate that it may be impaired. A qualitative assessment is performed to determine whether it is more likely than not that the reporting unit's fair value is less than its carrying value. We perform a quantitative impairment test only if we conclude that it is more likely than not that a reporting unit's fair value is less than the carrying amount. Determining the fair value of a reporting unit is judgmental and involves the use of significant estimates and assumptions. The fair value of the reporting unit is determined by using both a discounted cash flow model and a market based model. The discounted cash flow model has many assumptions including future earnings projections, a long-term growth rate and discount rate. The market based model calculates fair value based on observed price multiples for similar companies. The fair values of each method are then weighted based on relevance and reliability in the current economic environment. We determine the amount of identifiable intangible assets based upon independent core deposit and insurance contract valuations at the time of acquisition. Intangible assets with finite useful lives, consisting primarily of core deposit and customer list intangibles, are amortized using straight-line or accelerated methods over their estimated weighted average useful lives, ranging from 10 to 20 years. Intangible assets with finite useful lives are evaluated for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. No such events or changes in circumstances occurred during the years ended December 31, 2023 and 2022. Variable Interest Entities Variable interest entities, or VIEs, are legal entities that generally either do not have equity investors with voting rights or that have equity investors that do not provide sufficient financial resources for the entity to support its activities. When an enterprise has both the power to direct the economic activities of the VIE and the obligation to absorb losses of the VIE or the right to receive benefits of the VIE, the entity has a controlling financial interest in the VIE. A VIE often holds financial assets, including loans, receivables or other property. The company with a controlling financial interest, the primary beneficiary, is required to consolidate the VIE into its Consolidated Balance Sheets. S&T has two wholly-owned trust subsidiaries, STBA Capital Trust I and DNB Capital Trust II, or the Trusts, for which it does not absorb a majority of expected losses or receive a majority of the expected residual returns. DNB Capital Trust II was acquired with the DNB merger. At inception, these Trusts issued floating rate trust preferred securities to the Trustees and used the proceeds from the sale to invest in junior subordinated debt securities issued by us. The Trusts pay dividends on the trust preferred securities at the same rate as the interest we pay on the junior subordinated debt held by the Trusts. The Trusts are VIEs with the third-party investors as their primary beneficiaries, and accordingly, the Trusts and their net assets are not included in our consolidated financial statements. However, the junior subordinated debt securities issued by S&T are included in liabilities in our Consolidated Balance Sheets. Qualified Affordable Housing We have made investments directly in Low Income Housing Tax Credit, or LIHTC, partnerships formed with third parties. As a limited partner in these operating partnerships, we receive tax credits and tax deductions for losses incurred by the underlying properties. These investments are amortized over a maximum of 10 years, which represents the period over which the tax credits will be utilized. Our investments in Low Income Housing Partnerships, or LIHPs, represent unconsolidated VIEs and the assets and liabilities of the partnerships are not recorded on our balance sheet. We have determined that we are not the primary beneficiary of these VIEs because we do not have the power to direct the activities that most significantly impact the economic performance of the partnership nor do we have both the obligation to absorb expected losses and the right to receive benefits. We use the cost method to account for these partnerships. These investments are recorded in other assets in our Consolidated Balance Sheets. Amortization expense is included in other noninterest expense in the Consolidated Statements of Net Income. OREO and Other Repossessed Assets OREO and other repossessed assets are included in other assets in the Consolidated Balance Sheets and are comprised of properties acquired through foreclosure proceedings or acceptance of a deed in lieu of a foreclosure. OREO and other repossessed assets are recorded at fair value less cost to sell at the time of acquisition and when subsequent declines in fair value occur. Subsequent declines in the fair value of OREO are recorded through a valuation allowance. Subsequent increases in the fair value reduce the valuation allowance, but only to the amount that does not exceed the OREO foreclosure date cost basis. Loan losses arising from the acquisition of any such property initially are charged against the ACL. Gains or losses realized upon disposition of these assets are recorded in other noninterest income or expense in the Consolidated Statements of Net Income depending on whether the net position is a gain or loss. Securities Held in a Deferred Compensation Plan A nonqualified deferred compensation plan is offered to certain management employees providing an opportunity to continue to defer income on a tax deferred basis in excess of annual contribution or compensation limits for qualified plans. The plan assets are held in a grantor trust, are legally assets of S&T and are beneficially owned by the participants. The assets are available to satisfy the claims of general creditors in the event we would need to file bankruptcy. Securities held in the nonqualified deferred compensation plan are recorded in other assets in the Consolidated Balance Sheets at fair value. A corresponding deferred compensation liability is recorded in other liabilities in the Consolidated Balance Sheets. Gains and losses related to the change in value of plan assets are recorded in other noninterest income and salaries and employee benefits expense in our Consolidated Statements of Net Income, resulting in no impact to net income. Mortgage Servicing Rights MSRs are recognized as separate assets when a mortgage loan is sold. MSRs represents the estimated fair value of future net cash flows expected to be realized for performing the servicing activities. The fair value of the MSRs is estimated by calculating the present value of estimated future net servicing cash flows, considering expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors, which are determined based on current market conditions. The expected rate of mortgage loan prepayments is the most significant factor driving the value of MSRs. Increases in mortgage loan prepayments reduce estimated future net servicing cash flows because the life of the underlying loan is reduced. MSRs are reported in other assets in the Consolidated Balance Sheets and are amortized into mortgage banking in noninterest income in the Consolidated Statements of Net Income in proportion to, and over the period of, the estimated future net servicing income of the underlying mortgage loans. MSRs are evaluated for impairment based on the estimated fair value of those rights. MSRs are stratified by certain risk characteristics, primarily loan term and note rate. If temporary impairment exists within a risk stratification tranche, a valuation allowance is established through a charge to income equal to the amount by which the carrying value exceeds the estimated fair value. If it is later determined that all or a portion of the temporary impairment no longer exists for a particular tranche, the valuation allowance is reduced. Derivative Financial Instruments Derivatives are recognized as either other assets or other liabilities on the balance sheet at fair value. All derivatives are evaluated at inception to determine whether it is a hedging or non-hedging activity. The accounting for changes in the fair value of derivatives depends on whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting based on whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Pursuant to our agreements with various financial institutions, we may receive collateral or may be required to post collateral based upon mark-to-market positions. Beyond unsecured threshold levels, collateral in the form of cash or securities may be made available to counterparties of interest rate swap transactions. Interest income on collateral receivable is included in loan interest income in the Consolidated Statements of Net Income. Interest expense on collateral payable is included in borrowings, junior subordinated debt securities and other interest expense in the Consolidated Statements of Net Income. Derivatives contain an element of credit risk, the possibility that we will incur a loss because a counterparty, which may be a financial institution or a customer, fails to meet its contractual obligations. All derivative contracts with financial institutions may be executed only with counterparties approved by our Asset and Liability Committee, or ALCO, and derivatives with customers may only be executed with customers within credit exposure limits approved in accordance with our credit policy. We have entered into agreements with counterparty financial institutions, which include master netting agreements that provide for the net settlement of all contracts with a single counterparty in the event of default. We elect, however, to account for all derivatives with counterparty institutions on a gross basis in the Consolidated Balance Sheets. Interest Rate Swaps Designated as Hedging Instruments As part of our interest rate risk management strategy, we use interest rate swaps to add stability to interest income and to manage exposure to interest rate movements. Interest rate swaps designated as cash flow hedges involve the receipt of fixed-rate amounts from a counterparty in exchange for making variable rate payments over the life of the agreements without exchange of the underlying notional amount. 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 earnings effect of the hedged forecasted transactions in a cash flow hedge. As long as the cash flow hedge continues to qualify for hedge accounting, the entire change in the fair value of the hedging instrument is recognized in OCI, net of applicable taxes, and reclassified into interest income as interest payments are received. The change in the fair value is included in the change in other liabilities in the Consolidated Statements of Cash Flows. Interest Rate Contracts with Customers Interest rate swaps are contracts in which a series of interest rate flows (fixed and variable) are exchanged over a prescribed period. The notional amounts on which the interest payments are based are not exchanged. These derivative positions relate to transactions in which we enter into an interest rate swap with a commercial customer, while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each transaction, we agree to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on the same notional amount at a fixed rate. At the same time, we agree to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows our customer to effectively convert a variable rate loan to a fixed rate loan, while we continue to receive a variable amount of interest on the loan. These agreements could have floors or caps on the contracted interest rates. Interest rate swaps with customers and the corresponding offsetting interest rate swap with a financial institution are considered derivatives, but are not accounted for using hedge accounting. As such, changes in the estimated fair value of the derivatives are recorded in current earnings and included in other noninterest income in the Consolidated Statements of Net Income and included in the change in other assets and other liabilities in the Consolidated Statements of Cash Flows. Interest Rate Lock Commitments and Forward Sale Contracts In the normal course of business, we sell originated mortgage loans into the secondary mortgage loan market. We also offer interest rate lock commitments to potential borrowers. The commitments are generally for a period of 60 days and guarantee a specified interest rate for a loan if underwriting standards are met, but the commitment does not obligate the potential borrower to close on the loan. Accordingly, some commitments expire prior to becoming loans. We may encounter pricing risks if interest rates increase significantly before the loan can be closed and sold. We may utilize forward sale contracts in order to mitigate this pricing risk. Whenever a customer desires these products, a mortgage originator quotes a secondary market rate guaranteed for that day by the investor. The rate lock is executed between the mortgagee and us and in turn a forward sale contract may be executed between us and the investor. Both the rate lock commitment and the corresponding forward sale contract for each customer are considered derivatives, but are not accounted for using hedge accounting. As such, changes in the estimated fair value of the derivatives during the commitment period are recorded in current earnings and included in mortgage banking in the Consolidated Statements of Net Income. Treasury Stock The repurchase of our common stock is recorded at cost. At the time of reissuance, the treasury stock account is reduced using the average cost method. Gains and losses on the reissuance of common stock are recorded in additional paid-in capital. The Inflation Reduction Act of 2022 created a new excise tax equal to 1 percent of the fair value of shares repurchased, effective after December 31, 2022. The excise tax is included in the cost of treasury stock with an offset to other liabilities in the Consolidated Balance Sheets. The excise tax liability is reduced by the fair market value of any reissuance occurring in the same taxable year. Revenue Recognition - Contracts with Customers We earn revenue from contracts with our customers when we have completed our performance obligations and recognize that revenue when services are provided to our customers. Our contracts with customers are primarily in the form of account agreements. Generally, our services are transferred at a point in time in response to transactions initiated and controlled by our customers under service agreements with an expected duration of one year or less. Our customers have the right to terminate their service agreements at any time. We do not defer incremental direct costs to obtain contracts with customers that would be amortized in one year or less. These costs are primarily salaries and employee benefits recognized as expense in the period incurred. Service charges on deposit accounts - We recognize monthly service charges for both commercial and personal banking customers based on account fee schedules. Our performance obligation is generally satisfied and the related revenue recognized at a point in time or over time when the services are provided. Other fees are earned based on specific transactions or customer activity within the customers' deposit accounts. These are earned at the time the transaction or customer activity occurs. Debit and credit card services - Interchange fees are earned whenever debit and credit cards are processed through third-party card payment networks. ATM fees are based on transactions by our customers' and other customers' use of our ATMs or other ATMs. Debit and credit card revenue is recognized at a point in time when the transaction is settled. Our performance obligation to our customers is generally satisfied and the related revenue is recognized at a point in time when the service is provided. Third-party service contracts include annual volume and marketing incentives which are recognized over a period of twelve months when we meet thresholds as stated in the service contract. Wealth management services - Wealth management services are primarily comprised of fees earned from the management and administration of trusts, assets under administration and other financial advisory services. Generally, wealth management fees are earned over a period of time between monthly and annually, per the related fee schedules. Our performance obligations with our customers are generally satisfied when we provide the services as stated in the customers' agreements. The fees are based on a fixed amount or a scale based on the level of services provided or amount of assets under management. Other fee revenue - Other fee revenue includes a variety of other traditional banking services such as, electronic banking fees, letters of credit origination fees, wire transfer fees, money orders, treasury checks, check sale fees and transfer fees. Our performance obligations are generally satisfied at a point in time and fee revenue is recognized when the services are provided or the transaction is settled. Wealth Management Fees Assets held in a fiduciary capacity by our subsidiary bank, S&T Bank, are not our assets and are therefore not included in our consolidated financial statements. Wealth management fee income is reported in the Consolidated Statements of Net Income on an accrual basis. Stock-Based Compensation Stock-based compensation includes restricted stock awards and restricted stock units, which are measured using the fair value at the time of issuance. A Monte Carlo simulation is used to estimate the fair value of performance-based restricted stock with a market condition. The grant date fair value is recognized over the period during which the recipient is required to provide service in exchange for the award. Compensation expense for time-based restricted stock is recognized ratably over the period of service based on fair value on the grant date. Compensation expense for performance-based restricted stock is recognized ratably over the remaining vesting period if the likelihood of meeting the performance measure is probable, based on the fair value on the grant date. We estimate expected forfeitures when stock-based awards are granted and record compensation expense only for awards that are expected to vest. Pensions The expense for S&T Bank’s qualified and nonqualified defined benefit pension plans is actuarially determined using the projected unit credit actuarial cost method. It requires us to make economic assumptions regarding future interest rates and asset returns and various demographic assumptions. We estimate the discount rate used to measure benefit obligations by applying the projected cash flow for future benefit payments to a yield curve of high-quality corporate bonds available in the marketplace and by employing a model that matches bonds to our pension cash flows. The expected return on plan assets is an estimate of the long-term rate of return on plan assets, which is determined based on the current asset mix and estimates of return by asset class. We recognize in the Consolidated Balance Sheets an asset for the plan’s overfunded status or a liability for the plan’s underfunded status. Gains or losses related to changes in benefit obligations or plan assets resulting from experience different from that assumed are recognized as OCI in the period in which they occur. To the extent that such gains or losses exceed 10 percent of the greater of the projected benefit obligation or plan assets, they are recognized as a component of pension costs over the future service periods of actively employed plan participants. The funding policy for the qualified plan is to contribute an amount each year that is at least equal to the minimum required contribution, but not more than the maximum amount permissible for taxable plan sponsors. Our nonqualified plans are unfunded. On January 25, 2016, the Board of Directors approved an amendment to freeze benefit accruals under the qualified and nonqualified defined benefit pension plans effective March 31, 2016. As a result, no additional benefits are earned by participants in those plans based on service or pay after March 31, 2016. The plan was previously closed to new participants effective December 31, 2007. Marketing Costs We expense all marketing-related costs, including advertising costs, as incurred. Income Taxes We estimate income tax expense based on amounts expected to be owed to the tax jurisdictions where we conduct business. On a quarterly basis, management assesses the reasonableness of our effective tax rate based upon our current estimate of the amount and components of net income, tax credits and the applicable statutory tax rates expected for the full year. We classify interest and penalties as an element of tax expense. Deferred income tax assets and liabilities are determined using the asset and liability method and are reported in other assets or other liabilities, as appropriate, in the Consolidated Balance Sheets. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities and recognizes enacted changes in tax rate and laws. When deferred tax assets are recognized, they are subject to a valuation allowance based on management’s judgment as to whether realization is more likely than not. Accrued taxes represent the net estimated amount due to taxing jurisdictions and are reported in other assets or other liabilities, as appropriate, in the Consolidated Balance Sheets. We evaluate and assess the relative risks and appropriate tax treatment of transactions and filing positions after considering statutes, regulations, judicial precedent and other information and maintain tax accruals consistent with the evaluation of these relative risks and merits. Changes to the estimate of accrued taxes occur periodically due to changes in tax rates, interpretations of tax laws, the status of examinations being conducted by taxing authorities and changes to statutory, judicial and regulatory guidance. These changes, when they occur, can affect deferred taxes, accrued taxes, and the current period’s income tax expense and can be significant to our operating results. Tax positions are recognized as a benefit only if it is more likely than not that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50 percent likely of being realized on examination. For tax positions not meeting the more likely than not test, no tax benefit is recorded. Earnings Per Share Basic and diluted earnings per share, or EPS, are calculated using the more dilutive of either the treasury stock method or the two-class method. Unvested share-based payment awards that contain nonforfeitable rights to dividends are considered participating securities under the two-class method. Income allocated to common shareholders is then divided by the weighted average number of common shares outstanding during the period. Potentially dilutive securities are excluded from the basic EPS calculation. Under the treasury stock method, the weighted average number of common shares outstanding is increased by the potentially dilutive common shares. For the two-class method, diluted EPS is calculated for each class of shareholders using the weighted average number of shares attributed to each class. Potentially dilutive common shares are related to restricted stock. Recently Adopted Accounting Standards Updates, or ASU, or Updated Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments in this ASU provided optional guidance for a limited period of time to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting. The amendments provided optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts and other transactions affected by the anticipated transition away from the London Inter-Bank Offered Rate, or LIBOR, toward new interest rate benchmarks. The optional guidance generally allowed for the modified contract to be accounted for as a continuation of the existing contract and does not require contract remeasurement at the modification date or reassessment of a previous accounting determination. The amendments in this ASU were effective as of March 12, 2020 through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, Reference Rate Addendum (Topic 848) which clarified that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The guidance was effective for all entities as of March 12, 2020 through December 31, 2022. In December 2022, the FASB issued ASU No 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. The amendments in this ASU defer the sunset date for applying the reference rate reform relief by two years to December 31, 2024. We adopted ASU 2020-04 and ASU 2021-01 on January 1, 2022 and ASU 2022-06 upon issuance. We utilized the LIBOR transition relief as contract modifications were made during the course of the reference rate reform transition period. ASU 2020-04, ASU 2021-01 and ASU 2022-06 did not have a material impact on our consolidated financial statements. Financial Instruments Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures In March 2022, the FASB issued ASU 2022-02, Financial Instruments Credit Losses (Topic 326): Troubled Debt Restructuring and Vintage Disclosures. The guidance eliminates the “once a TDR, always a TDR” requirement for loan disclosures and requires disclosures about the performance of modified loans to borrowers experiencing financial difficulty in the 12 months following the modification. The amendments eliminate the recognition and measurement guidance related to TDRs for creditors that have adopted ASC 326 Financial Instruments - Credit Losses. We adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, on January 1, 2020. ASC 326 requires the recognition of lifetime expected credit losses when a loan is originated or acquired, so the effect of credit losses that occur in loans modified in TDRs is already included in the allowance for credit losses. ASU 2022-02 requires a creditor to apply the loan refinancing and restructuring guidance in ASC 310-20 (consistent with the accounting for other loan modifications) to determine whether a modification results in a new loan or a continuation of an existing loan. It also requires enhanced disclosures for modifications in the form of interest rate reductions, principal forgiveness, other-than-insignificant payment delays or term extensions (or combinations thereof) of loans made to borrowers experiencing financial difficulty. Disclosures are required regardless of whether a modification of a loan to a borrower experiencing financial difficulty results in a new loan. The objective of the disclosures is to provide information about the type and magnitude of modifications and the degree of their success in mitigating potential credit losses. The amendments in this ASU were effective for fiscal years beginning after December 15, 2022, and interim periods therein. We adopted ASU 2022-02, as of January 1, 2023, using a modified retrospective transition approach. Results for reporting periods beginning after January 1, 2023 are presented under ASU 2022-02 while prior period amounts continue to be reported in accordance with previously applicable GAAP. Under the previously applicable accounting guidance, commercial TDRs were individually assessed to determine if a specific reserve was required in the allowance for credit losses, or ACL. The elimination of TDRs resulted in these loans being included in homogenous pools. The adoption of this ASU resulted in a day one cumulative effective adjustment of $0.6 million which increased our ACL and decreased retained earnings. Refer to Note 6 Loans and Allowance for Credit Losses for additional disclosures related to modifications of loans to borrowers experiencing financial difficulty as well as gross charge-off vintage disclosures. Accounting Standards Issued But Not Yet Adopted Investments Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method In March 2023, the FASB issued ASU 2023-02, Investments Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method to allow reporting entities to consistently account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits. If certain conditions are met, a reporting entity may elect to account for its tax equity investments by using the proportional amortization method regardless of the program from which it receives income tax credits, instead of only low-income-housing tax credit, or LIHTC, structures. This amendment also eliminates certain LIHTC specific guidance aligning the accounting with other equity investments in tax credit structures. Under the proportional amortization method, the equity investment is amortized in proportion to the income tax credits and other income tax benefits received, Amortization expense and the income tax benefits are required to be presented on a net basis in income tax expense on the Consolidated Statements of Net Income. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. We adopted this ASU, as of January 1, 2024, using a modified retrospective transition approach, which resulted in an immaterial cumulative effect adjustment being recorded to retained earnings related to the transition of the cost method to the proportional amortization method on LIHTC partnerships. Additional disclosure requirements will have minimal impact to our consolidated financial statements. Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures to improve disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This update does not change how a public entity identifies its operating segments; however, it does require that an entity that has single reportable segment provide all the disclosures required by the amendments in this update. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. A public entity should apply the amendments in this update retrospectively to all prior periods presented in the consolidated financial statements. Early adoption is permitted. We currently have one reportable operating segment, Community Banking. This ASU will not impact our consolidated financial statements and will have minimal impact to to our disclosures, requiring identification of the chief operating decision maker and the information used to make operating decisions and to allocate resources. Income Taxes (Topic 740) Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures to enhance the transparency and decision usefulness of the disclosures. The amendments in this update address investor requests for more transparency about income tax information through improvements to disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments in this update are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual consolidated financial statements that have not yet been issued. This ASU is not expected to have a significant impact on disclosures, and will not impact our consolidated financial statements.
