Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies (a) Nature of Operations Northwest Bancshares, Inc., a Maryland corporation headquartered in Columbus, Ohio, is the b ank holding company for its wholly owned subsidiary, Northwest Bank. Northwest Bank, a Pennsylvania chartered savings bank, offers a complete line of business and personal banking products, as well as treasury management solutions and wealth management services through its 142 banking locations in Pennsylvania, New York, Ohio, and Indiana. We have determined that we have one reportable business segment. (b) Principles of Consolidation The Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries after elimination of all intercompany accounts and transactions. (c) Cash and Cash Equivalents For purposes of the statements of financial condition and cash flows, cash and cash equivalents include cash and amounts due from banks, interest-bearing deposits in other financial institutions, federal funds sold, and other short-term investments with original maturities of three months or less. (d) Marketable Securities We classify marketable securities at the time of purchase as held-to-maturity, available-for-sale, or trading. Securities for which management has the intent and ability to hold until maturity are classified as held-to-maturity and are carried at cost, adjusted for amortization of premiums and accretion of discounts on a level yield basis (amortized cost). If it is management’s intent at the time of purchase to hold securities for an indefinite period of time and/or to use such securities as part of its asset/liability management strategy, the securities are classified as available-for-sale and are carried at fair value, with unrealized gains and losses reported as accumulated other comprehensive income/(loss), a separate component of shareholders’ equity, net of tax. Securities classified as available-for-sale include securities that may be sold in response to changes in interest rates, resultant prepayment risk, or other market factors. Securities that are bought and held principally for the purpose of selling them in the near term are classified as trading and are reported at fair value, with changes in fair value included in earnings. The cost of securities sold is determined on a specific identification basis. We held no securities classified as trading at or during the years ended December 31, 2023 and 2022. Fair values are determined as described in Note 16. Throughout the year we validate the prices received from third parties by comparing them to prices provided by a different independent pricing service. We have reviewed the detailed valuation methodologies provided to us by our pricing services. On a quarterly basis, we measure expected credit losses on held-to-maturity debt securities on a collective basis by major security type and all of our held-to-maturity debt securities are residential mortgage-backed securities. Accrued interest receivable on held-to-maturity debt securities total ed $2.5 million and $2.8 million at December 31, 2023 and December 31, 2022, respectively, and is excluded from estimated credit losses. All of our r esidential mortgage-backed securities are issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. For available-for-sale debt securities in an unrealized loss position, on at least a quarterly basis, we review our investments for impairment. An investment security is deemed impaired if the fair value of the investment is less than its amortized cost. We consider both our intent to sell and the likelihood that we will not have to sell the investment securities before recovery of their amortized cost basis during our evaluation. If we intend to sell the investment security or if it is more likely than not that we will be required to sell the investment security, the entire impairment is recorded in earnings. For available-for-sale debt securities that do not meet this criteria, we evaluate whether the decline in fair value has resulted from credit losses or other factors. In making this assessment we consider the issuer of the securities and their creditworthiness, any changes to the rating of the security and any adverse conditions specifically related to the security, among other factors. Also, we may evaluate the business and financial outlook of the issuer, as well as broader economic performance indicators. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than amortized cost. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when we believe the uncollectibility of an available-for-sale security is confirmed or when there is an intent or requirement to sell the security. Accrued interest receivable d $1.6 million and $2.0 million at December 31, 2023 and December 31, 2022, respectively , and is excluded from the estimate of credit losses. A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days past due. The receivable for interest income that is accrued but not collected is reversed against interest income when the debt security is placed on nonaccrual status. No debt securities were on nonaccrual status as of December 31, 2023 and December 31, 2022. (e) Loans Receivable Our portfolio segments are based on the class of financing receivable. Additionally, the class of financing receivables are based on several factors including the method for monitoring and assessing credit risk and the risk characteristics of the financing receivables. Based on evaluation of the nature of our financing receivables, along with the nature and extent of exposure to credit risk arising from these receivables, our portfolio segments were determined to be Personal Banking and Business Banking loans. • Personal Banking loans consist of the following classes of financing receivables: ◦ Residential mortgage loans - fixed and adjustable rate mortgage loans ◦ Home equity loans - first and second mortgage loans and home equity lines of credit ◦ Vehicle loans - direct and indirect automobile and motorcycle loans ◦ Consumer loans - unsecured lines of credit, credit card loans, and other consumer loans • Business Banking loans consist of the following classes of financing receivables: ◦ Commercial real estate - multi-family commercial real estate loans are secured by multi-family residences, such as rental properties and loans secured by nonresidential properties such as hotels, commercial offices, medical buildings, manufacturing facilities and retail establishments, excluding owner-occupied loans, and including small business commercial real estate loans ◦ Commercial real estate - owner-occupied loans - commercial real estate loans secured by residential or non-residential properties ◦ Commercial loans - other commercial loans, including small business commercial loans and equipment finance loans Loans are reported at amortized cost. Amortized cost is the principal balance outstanding, net of any deferred purchased premiums an d discounts, deferred origination fees or costs and the allowance for credit losses. Accrued interest receivable totaled $42.2 million and $30.4 million at December 31, 2023 and December 31, 2022, respectively, and was reported in accrued interest receivable on the Consolidated Statements of Financial Condition. Accrued interest receivable is excluded from the amortized cost basis of loans and from the estimate of allowance for credit losses. Interest income on loans is credited to income as earned. Interest earned on loans for which no payments were received during the month is accrued at month end. Generally, accrued interest on loans more than 90 days delinquent is reversed and such loans are placed on nonaccrual status, except for credit card loans which are not placed in nonaccrual status based on delinquency. All loans are placed on nonaccrual status when principal or interest is 90 days or more delinquent or when there is reasonable doubt that interest or principal will not be collected in accordance with the contractual terms. Interest receipts on all nonaccrual loans are recognized as interest income when it has been determined that all principal and interest will be collected or are applied to principal when collectability of contractual principal is in doubt. Nonaccrual loans generally are restored to an accrual basis when principal and interest become current and a period of performance has been established in accordance with the contractual terms, typically six months. Occasionally, the Company modifies loans to borrowers in financial distress by providing principal forgiveness, term extensions, an other-than-insignificant payment delay, or interest rate reduction. When principal forgiveness is provided, the amount of forgiveness is charged off against the allowance for credit losses. Loan delinquency is measured based on the number of days since the payment due date. Past due status is measured using the loan’s contractual maturity date. Personal Banking loans are charged-off or charged down when they become 180 da ys delinquent, unless the borrower has filed for bankruptcy. Business Banking loans are charged-off or charged down when, in our opinion, they are no longer collectible or when it has been determined that the collateral value no longer supports the carrying value of the loan for loans that are collateral dependent. Loan fees and certain direct loan origination costs are deferred and the net deferred fee or cost is then recognized using the level-yield method over the contractual life of the loan as an adjustment to interest income. We identify certain residential mortgage loans and small business administration guaranteed loans which will be sold prior to maturity, as loans held-for-sale. These loans are recorded at fair value less estimated cost to sell. At December 31, 2023 and 2022, there were $8.8 million and $9.9 million of loans classified as held-for-sale, respectively. Acquired loans that are not considered purchased with credit deterioration (“PCD”) are initially measured at fair value with no carryover of the related allowance for credit losses. Determining the fair value of the loans involves estimating the amount and timing of principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. Acquired loans may be classified as PCD loans upon acquisition if they have experienced more than insignificant credit deterioration since origination. Loans are considered to have experienced more than insignificant credit deterioration if they are greater than 30 days past due, classified special mention or worse or on nonaccrual status. An allowance for credit losses on day 1 is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The allowance is recognized on day 1 by adding it to the fair value of the loan, which is the “Day 1 amortized cost”. There is no credit loss expense recognized on PCD loans because the initial allowance is established by grossing-up the amortized cost of the PCD loan. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision expense. (f) Allowance for Credit Losses and Provision for Credit Losses The allowance for credit losses is deducted from, or added to, the loan’s amortized cost basis to present the net amount expected to be collected on our lending portfolios. We estimate the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Loans are charged off against the allowance when we believe that a loan balance is confirmed to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Expected credit losses are estimated over the contractual term of the loans, adjusted for prepayments. The contractual term excludes expected extensions, renewals and modifications or the extension or renewal option is included in the contract and is not unconditionally cancellable by the Company. Credit card receivables do not have stated maturities. In determining the estimated life of a credit card receivable, we first estimate the future cash flows expected to be received and then apply those expected future cash flows to the credit card balance. The allowance for credit losses is measured on a collective (“pool”) basis when similar risk characteristics exist. For the purpose of calculating portfolio-level reserves, we have grouped our loans into seven segments: residential mortgage loans, home equity loans, vehicle loans, consumer loans, commercial real estate loans, commercial real estate owner-occupied and commercial loans. The allowance for credit losses is measured at the pool level utilizing loan-level inputs wherever possible. We use a twenty-four month forecasting period and revert to historical average loss rates thereafter. The reasonable and supportable forecast is based on a probability-weighted multiple macroeconomic forecast approach and obtained from a third party vendor. Reversion to the mean takes place over a twelve-month period. Our loss rate models utilize a linear reversion method. For our probability of default (“PD”)/loss given default (“LGD”) models we revert the PD utilizing exponential reversion, which is an accelerated method, and the LGD utilizing a linear reversion method. Historical average loss rates are calculated using historica l data beginning in 2009 through the current period. As part of the analysis as of December 31, 2023, we considered the most recent macroeconomic forecasts available. Mortgage and Home Equity Loans The allowance for credit losses within the mortgage and home equity loan pools is calculated using a non-discounted cash flow method through a PD, LGD, and prepayment model developed by an external third-party and adjusted for asset specific characteristics. These classes are further divided into smaller pools of loans with similar risk characteristics such as: lines versus loans, fixed versus variable, senior lien position versus junior lien position, among other things. For each pool, the models project default rates, prepayment rates, and severity rates. The models accept as inputs key risk drivers such as: current balance, original credit bureau score, original loan-to-value ratio, type of collateral, location of collateral, delinquency status, loan age, among other characteristics. They also utilize macroeconomic forecasts of home price indices, unemployment rates, gross domestic product, and others. Vehicle Loans The allowance for credit losses within the vehicle loan pool is calculated using a non-discounted cash flow model through a PD, LGD, and prepayment model developed by an external third-party and adjusted for asset specific risk characteristics. These classes are further divided into smaller pools of loans with similar risk characteristics such as: cars, trucks and powersport vehicles and recreational vehicles. Monthly probabilities of default and prepayments are estimated for each loan, along with estimates of exposure at default and loss given default. The model accepts as inputs key risk drivers such as loan, borrower, and collateral characteristics. It also uses macroeconomic forecasts of used car price indices, gross domestic product, unemployment rates and others. Consumer Loans The allowance for credit losses within the consumer loan portfolio is calculated at the portfolio-level using a non-discounted cash flow method through a suite of loss rate models developed internally with the assistance of an external third-party. This class of financing receivables is further divided into credit cards, unsecured lines of credit and other consumer loans. The allowance for credit losses for credit cards and unsecured lines of credit is calculated using two transition matrix models to project portfolio-level net charge-off rates. Both models use current balance and delinquency status as key risk drivers. These models are not natively sensitive to macroeconomic forecasts. The necessary adjustments to account for current and expected macroeconomic conditions is captured via our qualitative adjustment framework. For other consumer loans, a regression model is used to project portfolio-level net charge-off rates. This model uses borrower information and macroeconomic forecasts as key inputs. Commercial Real Estate Loans The commercial real estate loan class is further segmented into smaller pools of loans with similar risk characteristics, commercial real estate loans and small business commercial real estate loans. The allowance for credit losses for the commercial real estate loan portfolio is calculated at the pool level using a non-discounted cash flow method through a PD/LGD model developed by an external third-party. This model projects default and severity rates. The model accepts as inputs key risk drivers such as: current balance, original loan-to-value-ratio, type of collateral, location of collateral, delinquency status, loan age, obligor financial statement information, and expected prepayment rates, among other characteristics. It also utilizes macroeconomic forecasts of commercial real estate price indices, unemployment rates, gross domestic product and others. The allowance for credit losses for commercial real estate small business portfolio is calculated at a borrower-level with a PD/LGD model. Separate models were built by industry segment. Each model was built with a logistic regression model except for the U.S. Small Business Administration (SBA) and Agriculture sub-portfolios. For SBA, a portfolio-level fractional logit model was developed; the small Agriculture segment uses a simple long-run average loss rate. The LGD model is assumption-based and assigns varying LGDs by industry segment. The models ’ overall key inputs are borrower and collateral characteristics and macroeconomic forecasts including real GDP, unemployment, home price appreciation, and real disposable personal income. Commercial Loans and Commercial Real Estate - Owner Occupied Loans The commercial loan class is further segmented into smaller pools of loans with similar risk characteristics, commercial loans and commercial small business loans, including equipment finance loans. The allowance for credit losses for the commercial loan portfolio and the commercial real estate - owner occupied loan portfolio is calculated at the pool level using a non-discounted cash flow method through a PD/LGD model developed by an external third-party. The commercial loan portfolio and the commercial real estate owner occupied loan portfolio models project default and severity rates. The model accepts as inputs key risk drivers such as the obligor financial statement information, collateral type, the obligor’s primary industry, expected prepayment rates, among other characteristics. It also utilizes macroeconomic forecasts of unemployment rates, gross domestic product, corporate bond spreads, and others. The allowance for credit losses for commercial small business loans is calculated at a borrower-level with a PD/LGD model. Separate models were built by industry segment. Each model was built with a logistic regression model except for the U.S. Small Business Administration (SBA) and Agriculture sub-portfolios. For SBA, a portfolio-level fractional logit model was developed; the small Agriculture segment uses a simple long-run average loss rate. The LGD model is assumption-based and assigns varying LGDs by industry segment. The models ’ overall key inputs are borrower and collateral characteristics and macroeconomic forecasts including real GDP, unemployment, home price appreciation, and real disposable personal income. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. When we determine that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs. If this criteria is not met, a discounted cash flow method is used to determine the allowance for credit losses. All changes in the discounted cash flow method over time are reported in the allowance for credit losses. The allowance calculation is also supplemented with qualitative reserves that takes into consideration the current portfolio and specific risk characteristics, such as changes in underwriting standards, portfolio mix, delinquency level, or term, as well as changes in environmental conditions, among other factors, that have occurred but are not yet reflected in the quantitative model component. The modifications to borrowers experiencing financial distress are included in their respective portfolio segment and the current loan balance and updated loan terms are run through their respective allowance models to arrive at the quantitative portion of the allowance for credit losses. Subsequent performance of the loans will be measured by delinquency status and will be captured through our models or our qualitative factor assessment, as deemed appropriate. If we no longer believe the loan demonstrates similar risks to their respective portfolio segment, an individual assessment will be performed. Upon the Company’s determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount. For off-balance-sheet credit exposures, we estimate expected credit losses over the contractual period in which we are exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable. The liability for credit losses on off-balance-sheet credit exposures is adjusted through a provision for credit loss - unfunded commitments expense on the Consolidated Statements of Income. We estimate the liability balance using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. The estimate includes a consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. Off-balance-sheet exposures that are not unconditionally cancellable have been identified for the mortgage, home equity, commercial real estate, and commercial loan portfolios. (g) Real Estate Owned Real estate owned is comprised of property either acquired through foreclosure or voluntarily conveyed by borrowers. These assets are recorded on the date acquired at the lower of the loan balance or fair value of the collateral, less estimated disposition costs, with the fair value being determined by an appraisal. Any initial write-down is charged to the allowance for credit losses. Subsequently, foreclosed assets are valued at the lower of the amount recorded at acquisition date or the current fair value, less estimated disposition costs. Any subsequent write-down or gains or losses realized from the disposition of such property are credited or charged to noninterest income. (h) Restricted Investment in FHLB Stock Federal law requires a member institution of the FHLB system to hold stock of its district FHLB according to a predetermined formula. FHLB stock is carried at cost and evaluated for impairment based on the ultimate recoverability of the par value. FHLB stock can only be purchased, redeemed and transferred at par value. Dividends are reported in interest income in the Consolidated Statements of Income. (i) Premises and Equipment Premises and equipment are carried at cost, less accumulated depreciation and amortization. Depreciation is accumulated on a straight-line basis over the estimated useful lives of the related assets. Estimated lives range from three . Amortization of leasehold improvements is accumulated on a straight-line basis over the terms of the related leases or the useful lives of the related assets, whichever is shorter. (j) Goodwill Goodwill is generated from the premium paid for an acquisition and is allocated to reporting units, which are either our reportable segments or one level below. Reporting units are identified based upon analyzing each individual operating segment. A reporting unit is defined as a distinct, separately identifiable component of an operating segment for which complete, discrete financial information is available that management regularly reviews. Goodwill is not subject to amortization but is tested for impairment at least annually and possibly more frequently if certain events occur or changes in circumstances arise. In testing goodwill for impairment, we have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, after assessing all events and circumstances, we determine it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the two-step impairment test would be unnecessary. However, if we conclude otherwise, it would then be required to perform the first step of the goodwill impairment test and continue to the second step, if necessary. Step 1 requires the fair value of each reporting unit be compared to its carrying amount, including goodwill. Determining the fair value of a reporting unit requires a high degree of subjective judgment, including developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions and selecting an appropriate control premium. We have established June 30 of each year as the date for conducting our annual goodwill impairment assessment. Quarterly, we evaluate if there are any triggering events that would require an update to our previous assessment. We conducted our annual impairment assessment as o f June 30, 2023 b y first performing a qualitative assessment of goodwill to determine if it was more likely than not that the fair value was less than the carrying value. In performing a qualitative analysis, factors considered include, but are not limited to, macroeconomic conditions, industry and market conditions and overall financial performance. The results of the qualitative assessme nt for 2023 i ndicated that it was not more likely than not that the fair value of the reporting unit was less than the carrying value. Consequently, no additional quantitative impairment test was required and no impairment was recorded in 2023. Future events could cause us to conclude that goodwill has become impaired, which would result in recording an impairment loss. There were no events or changes in circumstance in our operations that would cause us to update the assessment performed as of June 30, 2023 and 2022. Accordingly, we have determined that goodwill is not impaired as of December 31, 2023 and 2022. (k) Core Deposit and Other Identifiable Intangibles Through the assistance of an independent third party, we analyze and prepare a core deposit study for all bank acquisitions or other identifiable intangible asset study, such as customer lists, for all non-bank acquisitions. The core deposit study reflects the cumulative present value benefit of acquiring deposits versus an alternative source of funding. The other identifiable intangible asset study reflects the cumulative present value benefit of acquiring the income stream from an existing customer base versus developing new business relationships. Based upon analysis, the amount of the premium related to the core deposits or other identifiable intangibles of the business purchased is calculated along with the estimated life of the intangible. The intangible, which is recorded in other intangible assets, is then amortized to expense on an accelerated basis over an approximate life of typically betwe en seven (l) Bank-Owned Life Insurance We own insurance on the lives of a certain group of current and former employees and directors. The policies were purchased to help offset the increase in the costs of various benefit plans, including healthcare, as well as the directors deferred compensation plan. The cash surrender value of these policies is included as an asset on the Consolidated Statements of Financial Condition and any increases in the cash surrender value are recorded as tax-free noninterest income on the Consolidated Statements of Income. In the event of the death of an insured individual covered by these policies, after distribution to the insured’s beneficiaries, if any, we receive a tax-free death benefit, which is recorded as noninterest income. (m) Deposits Interest on deposits is accrued and charged to expense monthly and is paid or credited in accordance with the terms of the accounts. (n) Revenue Recognition Revenue that is not associated with our financial assets and financial liabilities is recognized when performance obligations under the terms of a contract with our customers are satisfied. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. The majority of our revenue continues to be recognized at the point in time when the services are provided to our customers. (o) Pension Plans We maintain multiple noncontributory defined benefit pension plans (“Pension Plan”) for substantially all of our employees. The net periodic pension cost has been calculated using service cost, interest cost, expected returns on plan assets and net amortization. The other components of the net periodic benefit cost are included in other expense on the Consolidated Statement of Income and are reported separately from the service costs. Pension expense and obligations depend on assumptions used in calculating such amounts. These assumptions include discount rates, anticipated salary increases, interest costs, expected return on plan assets, mortality rates, and other factors. In determining the projected benefit obligations for pension benefits at December 31, 2023 and 2022, we u sed a discount rate of 4.79% and 4.99%, respectively. We use the FTSE (previously Citigroup) Pension Liability Index rates matching the duration of our benefit payments as of the measurement date, December 31, to determine the discount rate. (p) Income Taxes We join with our wholly owned subsidiaries in filing a consolidated federal income tax return. In accordance with an intercompany tax allocation agreement, the applicable federal income tax expense or benefit is allocated to each subsidiary based upon taxable income or loss calculated on a separate company basis. Each subsidiary is responsible for payment of its own federal income tax liability or receives reimbursement of federal income tax benefit. In addition, deferred taxes are calculated and maintained on a separate company basis. We account for income taxes under the asset and liability method. The objective of the asset and liability method is to establish deferred tax assets and liabilities for temporary differences between the financial reporting and tax basis

Accounting Policies [Abstract]
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosure.” This ASU eliminates the accounting guidance for troubled debt restructurings (“TDRs”), while enhancing disclosure requirements for certain loan modifications when a borrower is experiencing financial difficulty. This ASU also requires the disclosure of current period gross write-offs by year for origination for financing receivables. This guidance is effective for annual periods beginning after December 15, 2022, including interim periods within those years, with early adoption permitted. This ASU is applied prospectively to modifications and write-offs beginning on the first day of the fiscal year of adoption. An entity may elect to adopt a modified retrospective transition method on the recognition and measurement of the TDR guidance. We adopted ASU 2022-02 using a modified retrospective transition approach related to the recognition and measurement of the TDR guidance and on a prospective basis for modification and write-offs. As a result, the Company was not required to adjust its comparative period financial information for effects of the standard or make the new required ASU 2022-02 disclosure for periods before the date of adoption (i.e. January 1, 2023). This change did not have a material effect on our consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This ASU provides temporary optional guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The guidance provides expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. The amendments primarily include contract modifications and hedge accounting, as well as providing a one-time election for the sale or transfer of debt securities classified as held-to-maturity. This guidance was effective 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 to Topic 848”. This guidance extends the guidance of ASU 2022-04 from December 31, 2022 to December 31, 2024. In January 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform.” This ASU provides amendments, which are elective, and apply to all entities that have derivative instruments that use an interest rate for margining, discounting or contract price alignment of certain derivative instruments that are modified as a result of the reference rate reform. This ASU is effective upon issuance through December 31, 2024, and can be adopted at any time during this period.

All of these securities were issued by U.S. government agencies, U.S. government-sponsored enterprises, local municipalities, or represent corporate debt. The securities issued by the U.S. government agencies or U.S. government-sponsored enterprises are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. The corporate debt issues and securities issued by local municipalities were all highly rated by major rating agencies and have no history of credit losses. The unrealized losses were primarily attributable to changes in the interest rate environment and not due to the credit quality of these investment securities. The Company does not have the intent to sell these investment securities and it is likely that we will not be required to sell these securities before their anticipated recovery, which may be at maturity. All of the Company ’ s held-to-maturity debt securities are issued by U.S. government-sponsored agencies or U.S. government-sponsored enterprises. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. The decline in fair value of the held-to-maturity debt securities were primarily attributable to changes in the interest rate environment and not due to the credit quality of these investment securities, therefore, the Company did not record an allowance for credit losses for these securities as of December 31, 2023. The following table presents the credit quality for our held-to-maturity securities, based on the latest information available as of December 31, 2023 (in thousands). The credit ratings are sourced from nationally recognized rating agencies, which include Moody ’ s and S&P, they are presented based on asset type.

A loan is considered to be collateral dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral.

When principal forgiveness is provided, the amount of forgiveness is charged off against the allowance for credit losses. In some cases, the Company provides multiple types of concessions to one loan. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as principal forgiveness, may be granted. For loans included in the “combination” columns below, multiple types of modifications have been made on the same loan within the current reporting period. The combination is at least two of the following: a term extension, principal forgiveness, an other-than-insignificant payment delay, and/or an interest rate reduction.

Subsequent performance of the loans will be measured by delinquency status and will be captured through our ACL models or our qualitative factor assessment, as deemed appropriate. If we no longer believe the loan demonstrates similar risks to their respective portfolio segment an individual assessment will be performed. Upon the Company’s determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount.

We analyze loans individually by classifying the loans by credit risk. Credit relationships greater than or equal to $1.0 million classified as special mention or substandard are reviewed quarterly for deterioration or improvement to determine if the loan is appropriately classified. We use the following definitions for risk ratings other than pass: Special Mention — Loans designated as special mention have specific, well-defined risk issues, which create a high level of uncertainty regarding the long-term viability of the business. Loans in this class are considered to have high-risk characteristics. A special mention loan exhibits material negative financial trends due to company-specific or systemic conditions. If these potential weaknesses are not mitigated, they threaten the borrower’s capacity to meet its debt obligations. Special mention loans still demonstrate sufficient financial flexibility to react to and positively address the root cause of the adverse financial trends without significant deviations from their current business strategy. Their potential weaknesses deserve our close attention and warrant enhanced monitoring. Substandard — Loans classified as substandard are inadequately protected by the current net worth and payment capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Doubtful — Loans classified as doubtful have all the weaknesses inherent in those classified as substandard. In addition, those weaknesses make collection or liquidation in full highly questionable and improbable. A loan classified as doubtful exhibits discernible loss potential, but a complete loss seems very unlikely. The possibility of a loss on a doubtful loan is high, but because of certain important and reasonably specific pending factors that may strengthen the loan, its classification as an estimated loss is deferred until a more exact status can be determined. Loss — Loans classified as loss are considered uncollectible and of such value that the continuance as a loan is not warranted. A loss classification does not mean that the loan has no recovery or salvage value; instead, it means that it is not practical or desirable to defer writing off all or a portion of a basically worthless loan even though partial recovery may be possible in the future. For Personal Banking loans a pass risk rating is maintained until they are greater than 90 days past due, and risk rating reclassification is based primarily on past due status of the loan. The risk rating categories can generally be described by the following groupings: Pass — Loans classified as pass are homogeneous loans that are less than 90 days past due from the required payment date at month-end. Substandard — Loans classified as substandard are homogeneous loans that are greater than 90 days past due from the required payment date at month-end, loans classified as TDRs, or homogenous retail loans that are greater than 180 days past due from the requirement payment date at month-end that has been written down to the value of underlying collateral, less costs to sell. Doubtful — Loans classified as doubtful are homogeneous loans that are greater than 180 days past due from the required payment date at month-end and not written down to the value of underlying collateral. These loans are generally charged-off in the month in which the 180 day period elapses.

The revolving line of credit with the FHLB of Pittsburgh carries a commitment of $250.0 million. The rate is adjusted daily by the FHLB of Pittsburgh, and any borrowings on this line may be repaid at any time without penalty. At December 31, 2023 and December 31, 2022, the balance of the revolving line of credit was $163.5 million and $51.3 million, respectively. At December 31, 2023 and December 31, 2022, collateralized borrowings due within one year were $35.5 million and $105.8 million, respectively. These borrowings are collateralized by cash or various securities held in safekeeping by the FHLB. At December 31, 2023, the carrying value of the cash and securities used as collateral was $92.0 million. At December 31, 2023 and December 31, 2022, collateral received was $24.9 million and $24.1 million, respectively. This represents collateral posted to us from our derivative counterparties. At December 31, 2023 and December 31, 2022, term notes payable to the FHLB of Pittsburgh due within one year were $175.0 million and $500.0 million, respectively. The December 31, 2023 total is made up of seven advances: $25.0 million at 5.76% maturing January 26, 2024; $25.0 million at 5.77% maturing January 31, 2024; $25.0 million at 5.73% maturing February 9, 2024; $25.0 million at 5.68% maturing February 13, 2024; $25.0 million at 5.70% maturing February 12, 2024; $25.0 million at 5.67% maturing February 20, 2024 and $25.0 million at 5.67% maturing February 29, 2024.

The subordinated notes, which qualify as Tier 2 capital, bear interest at an annual rate of 4.00%, payable semi-annually in arrears commencing on March 15, 2021, and a floating rate of interest equivalent to the 3-month Secured Overnight Financing Rate (“SOFR”) plus 3.89% payable quarterly in arrears commencing on December 15, 2025. During the year-ended December 31, 2022 the Company repurchased $10.2 million of subordinated notes leaving $114.8 million of subordinated notes outstanding as of December 31, 2023. The subordinated debt issuance costs of approximately $1.8 million are being amortized over five years on a straight-line basis into interest expense. At December 31, 2023 and December 31, 2022, subordinated debentures, net of issuance costs, were $114.2 million and $113.8 million, respectively. For the years ended December 31, 2023, December 31, 2022, and December 31, 2021 total interest expense paid on the subordinate notes was $4.9 million, $5.1 million, and $5.3 million, respectively. (b) Trust Preferred Securities The Company has seven statutory business trusts: Northwest Bancorp Capital Trust III, a Delaware statutory business trust, Northwest Bancorp Statutory Trust IV, a Connecticut statutory business trust, LNB Trust II, a Delaware statutory business trust, Union National Capital Trust I (“UNCT I”), a Delaware statutory business trust, Union National Capital Trust II (“UNCT II”), a Delaware statutory business trust, MFBC Statutory Trust I, a Delaware statutory trust, and Universal Preferred Trust, a Delaware statutory trust (the “Trusts”). The Trusts exist solely to issue preferred securities to third parties for cash, issue common securities to the Company in exchange for capitalization of the Trusts, invest the proceeds from the sale of trust securities in an equivalent amount of debentures of the Company, and engage in other activities that are incidental to those previously listed. The Trusts have invested the proceeds of the offerings in junior subordinated deferrable interest debentures issued by the Company. The structure of these debentures mirrors the structure of the trust-preferred securities. These subordinated debentures are the sole assets of the Trusts. As the shareholders of the trust preferred securities are the primary beneficiaries of the Trusts, the Trusts are not consolidated in our financial statements. The following table sets forth a summary of the cumulative trust preferred securities and the junior subordinated debt held by the Trust as of December 31, 2023 and 2022. Maturity date Interest rate Capital debt December 31, 2023 2022 Northwest Bancorp Capital Trust III December 30, 2035 3-month SOFR plus 1.38% $ 50,000 51,547 51,547 Northwest Bancorp Statutory Trust IV December 15, 2035 3-month SOFR plus 1.38% 50,000 51,547 51,547 LNB Trust II June 15, 2037 3-month SOFR plus 1.48% 7,875 8,119 8,119 Union National Capital Trust I (1) January 23, 2034 3-month SOFR plus 2.85% 8,000 7,999 7,975 Union National Capital Trust II (1) November 23, 2034 3-month SOFR plus 2.00% 3,000 2,796 2,768 MFBC Statutory Trust I (1) September 15, 2035 3-month SOFR plus 1.70% 5,000 3,788 3,684 Universal Preferred Trust (1) October 7, 2035 3-month SOFR plus 1.69% 5,000 3,778 3,674 $ 128,875 129,574 129,314 (1) Net of discounts due to the fair value adjustment made at the time of acquisition. Cash distributions on the trust securities are made on a quarterly basis to the extent interest on the debentures is received by the Trusts. We have the right to defer payment of interest on the subordinated debentures at any time, or from time-to-time, for periods not exceeding five years. If interest payments on the subordinated debentures are deferred, the distributions on the trust securities also are deferred. To date there have been no interest deferrals. Interest on the subordinated debentures and distributions on the trust securities is cumulative. Our obligation constitutes a full, irrevocable, and unconditional guarantee on a subordinated basis of the obligations of the trust under the preferred securities. For the years ended December 31, 2023, December 31, 2022, and December 31, 2021, total interest expense paid on the trust preferred securities was $9.4 million, $4.7 million, and $2.5 million respectively. The Trusts must redeem the preferred securities when the debentures are paid at maturity or upon an earlier redemption of the debentures to the extent the debentures are redeemed. All or part of the debentures may be redeemed at any time. Also, the debentures may be redeemed at any time if existing laws or regulations, or the interpretation or application of these laws or regulations, change causing: • the interest on the debentures to no longer be deductible by the Company for federal income tax purposes; • the trust to become subject to federal income tax or to certain other taxes or governmental charges; • the trust to register as an investment company; or • the preferred securities do not qualify as Tier I capital. We may, at any time, dissolve any of the Trusts and distribute the debentures to the trust security holders, subject to receipt of any required regulatory approvals.

The carryovers begin to expire in 2031 and are expected to be fully realized. We have $25.9 million of Indiana net operating loss carryovers subject to annual limitation as Indiana conforms to the Internal Revenue Code Section 382 at December 31, 2023. The carryovers begin to expire in 2025. Due to limitation, we do not currently expect to realize $7.6 million of the Indiana net operating loss carryover. This is netted against the net operating loss deferred tax asset in the preceding table. We recorded a valuation allowance against state deferred tax assets of a Northwest subsidiary since the subsidiary is not expected to utilize its deferred tax assets in the foreseeable future. This valuation allowance is netted against other deferred tax assets in the preceding table. Other than stated above, we have determined that no valuation allowance is necessary for the deferred tax assets because it is more likely than not that these assets will be realized through future reversals of existing temporary differences and through future taxable income. We will continue to review the criteria related to the recognition of deferred tax assets on a regular basis. We utilize a comprehensive approach to recognize, measure, present and disclose in our financial statements uncertain tax positions that the company has taken or expects to take on a tax return. We recognize interest accrued and penalties (if any) related to unrecognized tax benefits in income tax expense. The accrual for interest and penalties was not material for all years presented. The following table presents changes in unrecognized tax benefits at December 31, 2023, 2022 and 2021: Year ended December 31, 2023 2022 2021 Unrecognized tax benefits: Balance, beginning of year $ 473 241 331 Increases related to prior year tax positions 623 252 37 Decreases related to prior year tax positions (74) (28) (173) Increases related to current year tax positions 58 8 46 Balance, end of year $ 1,080 473 241 It is reasonably possible that over the next twelve months the amount of unrecognized tax benefits may change from the reevaluation of uncertain tax positions arising in examinations, in appeals, or in the courts, or from the closure of tax statutes. We do not expect any significant changes in unrecognized tax benefits during the next twelve months. We are subject to routine audits of our tax returns by the Internal Revenue Service as well as all states in which we conduct business. We are subject to audit by the Internal Revenue Service for the tax periods ended after December 31, 2019 and generally subject to audit by any state in which we conduct business for the tax periods ended after December 31, 2019.

Stockholders' Equity Note [Abstract]
Shareholders' Equity	Shareholders’ Equity Retained earnings are partially restricted in connection with regulations related to the insurance of deposit accounts, which requires Northwest to maintain certain statutory reserves. Northwest may not pay dividends on or repurchase any of its common stock if the effect thereof would reduce retained earnings below the level of adequate capitalization as defined by federal and state regulators. In tax years prior to fiscal 1997, Northwest was permitted, under the Internal Revenue Code (“IRC”), to deduct an annual addition to a reserve for bad debts in determining taxable income, subject to certain limitations. Bad debt deductions for income tax purposes are included in taxable income of later years only if the bad debt reserve is used subsequently for purposes other than to absorb bad debt losses. Because Northwest does not intend to use the reserve for purposes other than to absorb losses, no deferred income taxes have been provided prior to fiscal 1987. Retained earnings at December 31, 2023 and 2022 include approximately $39.1 million representing such bad debt deductions for which no deferred income taxes have been provided.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per common share (“EPS”) is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding for the period, without considering any dilutive items. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company. During the year ended December 31, 2023, 2,814,207 stock options were not included in the computation of diluted earnings per share because the stock options’ exercise price was more than the average market price of the common shares of $11.75. During the year ended December 31, 2022, 1,950,847 stock options were not included in the computation of diluted earnings per share because the stock options’ exercise price was more than the average market price of the common shares of $13.79. During the year ended December 31, 2021, 2,146,897 stock options were not included in the computation of diluted earnings per share because the stock options’ exercise price was more than the average market price of the common shares of $13.80. The following table sets forth the computation of basic and diluted earnings per share for the years ended December 31, 2023, 2022 and 2021.

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans (a) Pension Plans We maintain noncontributory defined benefit pension plans covering substantially all employees and members of our board of directors. Retirement benefits are based on certain compensation levels, age, and length of service. Contributions are based on an actuarially determined amount to fund not only benefits attributed to service to date but also for those expected to be earned in the future. In addition, we have an unfunded Supplemental Executive Retirement Plan (“SERP”) to compensate those executive participants eligible for the defined benefit pension plan whose benefits are limited by Section 415 of the IRC. We also sponsor a retirement savings plan in which substantially all employees participate. We provide a matching contribution of 100% of each employee’s contribution to a maximum of 4% of the employee’s compensation. Effective August 1, 2020, the Pension Plan was amended to include a soft freeze. The soft freeze will allow those employees in an eligible position that were hired, rehired, or acquired on or before July 31, 2020, to continue to vest and accrue additional benefits for each year they are credited with 1,000 hours or more. Employees that are hired, rehired, acquired, or transfer to an eligible job classification on or after August 1, 2020 are not eligible to participate in the Pension Plan. Total expense for the defined contribution retirement savings plan was $4.4 million, $3.6 million, and $4.6 million for the years ended December 31, 2023, 2022 and 2021, and net periodic pension expense for the defined benefit pension plan was a benefit of $1.1 million for the year ended December 31, 2023 and a total cost of $893,000 and $5.5 million for the years ended 2022 and 2021, respectively. Components of net periodic pension cost and other amounts recognized in other comprehensive income: The following table sets forth components of net periodic pension cost and other amounts recognized in other comprehensive income for the years ended December 31, 2023, 2022 and 2021. Years ended December 31, 2023 2022 2021 Defined benefit pension plan: Service cost $ 6,241 10,396 11,440 Interest cost 9,009 6,683 6,070 Expected return on plan assets (13,915) (15,454) (13,859) Amortization of prior service cost (2,254) (2,257) (2,322) Amortization of the net loss (219) 1,525 4,156 Net periodic pension cost, defined benefit pension plans (1,138) 893 5,485 Other changes in defined benefit pension plan recognized in other comprehensive income: Net gain (14,066) (28,222) (36,552) Amortization of prior service cost 2,254 2,257 2,322 Total recognized in other comprehensive income (11,812) (25,965) (34,230) Total recognized in net periodic pension cost and other comprehensive income $ (12,950) (25,072) (28,745) The estimated net gain and prior service credit for the defined benefit pension plan that will be amortized from accumulated other comprehensive income into net periodic cost ending December 31, 2024 is $71,000 and $2.3 million, respectively. The following table sets forth information for the defined benefit pension plans’ funded status at December 31, 2023 and 2022: December 31, 2023 2022 Change in benefit obligation: Benefit obligation at beginning of year $ 184,759 246,934 Service cost 6,241 10,396 Interest cost 9,009 6,683 Actuarial gain 935 (70,121) Benefits paid (15,748) (9,133) Benefit obligation at end of year 185,196 184,759 Change in plan assets: Fair value of plan assets at beginning of year 202,791 239,438 Actual return on plan assets 29,135 (27,970) Employer contributions 418 456 Benefits paid (15,748) (9,133) Fair value of plan assets at end of period 216,596 202,791 Funded status at end of year $ 31,400 18,032 The following table sets forth the assumptions used to develop the net periodic pension cost: Years ended December 31, 2023 2022 2021 Discount rate 4.99 % 2.75 % 2.39 % Expected long-term rate of return on assets 7.00 % 6.50 % 6.50 % Rate of increase in compensation levels 3.00 % 3.00 % 3.00 % The following table sets forth the assumptions used to determine benefit obligations at the end of each period: Years ended December 31, 2023 2022 2021 Discount rate 4.79 % 4.99 % 2.75 % Expected long-term rate of return on assets 7.00 % 6.50 % 6.50 % Rate of increase in compensation levels 3.00 % 3.00 % 3.00 % The expected long-term rate of return on assets is based on the expected return of each of the asset categories, weighted based on the median of the target allocation for each category. We use the FTSE (previously Citigroup) Pension Liability Index rates matching the duration of our benefit payments as of the measurement date to determine the discount rate. The accumulated benefit obligation for the funded defined benefit pension plan was $183.1 million, $182.3 million, and $243.6 million at December 31, 2023, 2022 and 2021, respectively. The accumulated benefit obligation for all unfunded defined benefit plans was $2.1 million, $2.5 million, and $3.3 million at December 31, 2023, 2022 and 2021, respectively. The following table sets forth certain information related to our pension plans: December 31, 2023 2022 Projected benefit obligation $ 185,196 184,759 Accumulated benefit obligation 185,196 184,759 Fair value of plan assets 216,596 202,791 Because of the current funding status, we do not anticipate a funding requirement during the year ending December 31, 2024. The investment policy as established by the Plan Administrative Committee, to be followed by the Trustee, is to invest assets based on the target allocations shown in the table below. To meet target allocation ranges set forth by the Plan Administrative Committee, periodically, the assets are reallocated by the Trustee. The investment policy is reviewed periodically to determine if the policy should be changed. Pension assets are conservatively invested with the goal of providing market or better returns with below market risks. Assets are invested in a balanced portfolio composed primarily of equities, fixed income, and cash or cash equivalent investments. The Trustee tries to maintain an approximate asset mix position of 20% to 50% bonds and 30% to 60% equities. A maximum of 10% may be invested in any one stock, including the stock of Northwest Bancshares, Inc. The objective of holding equity securities is to provide capital appreciation consistent with the ownership of the common stocks of medium to large companies. Acceptable bond investments are direct or agency obligations of the U.S. Government or investment grade corporate bonds. The average maturity of the bond portfolio shall not exceed ten years. The following table sets forth the weighted average asset allocation of defined benefit plans: December 31, Target allocation 2023 2022 Debt securities 20 – 50% 25 % 26 % Equity securities 30 – 60% 69 % 65 % Other 5 – 50% 6 % 9 % Total 100 % 100 % All of the assets held by the defined benefit pension plan are measured and recorded at estimated fair value on our balance sheet on a recurring basis as Level 1 assets, as defined by the fair value hierarchy defined in Note 16. The following table sets forth the pension plan assets as of December 31, 2023 and 2022. December 31, 2023 2022 Defined benefit pension assets: Common stock $ 71,192 61,552 Mutual funds 131,921 121,826 Money market funds 2,150 9,208 Other 11,333 10,205 Total defined benefit pension plan assets (1) $ 216,596 202,791 (1) The defined benefit pension plan statement of net assets also includes accrued interest and dividends resulting in net assets available for benefits of $217.0 million and $203.0 million, respectfully. The benefits expected to be paid in each year from 2024 to 2028 are $9.0 million, $9.5 million, $9.7 million, $10.1 million and $10.5 million, respectively. The aggregate benefits expected to be paid in the five years from 2029 to 2033 are $60.4 million. The expected benefits to be paid are based on the same assumptions used to measure our benefit obligations at December 31, 2023 and include estimated future employee service. (b) Post-retirement Healthcare Plan In addition to pension benefits, we provide post-retirement healthcare benefits for certain employees who were employed as of October 1, 1993 and were at least 55 years of age on that date. We use the accrual method of accounting for post-retirement benefits other than pensions. Components of net periodic benefit cost and other amounts recognized in other comprehensive income: The following table sets forth the net periodic benefit cost for the post-retirement healthcare benefits plan for the years ended December 31, 2023, 2022 and 2021: Years ended December 31, 2023 2022 2021 Interest cost $ 71 40 42 Amortization of net loss 39 6 14 Net period benefit cost $ 110 46 56 The following table sets forth other changes in the post-retirement healthcare plan’s plan assets and benefit obligations recognized in other comprehensive income: Years ended December 31, 2023 2022 2021 Net (gain)/loss $ (35) 183 (66) Total recognized in other comprehensive income $ (35) 183 (66) Total recognized in net periodic benefit cost and other comprehensive income $ 74 229 (10) The estimated net loss for the post-retirement healthcare benefit plan that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the year ending December 31, 2024 is $38,000. The following table sets forth the funded status of the post-retirement healthcare benefit plan at December 31, 2023 and 2022: December 31, 2023 2022 Change in benefit obligation: Benefit obligation at beginning of year $ 1,521 1,560 Interest cost 71 40 Actuarial loss 3 189 Benefits paid (209) (268) Benefit obligation at end of year $ 1,386 1,521 Change in plan assets: Employer contributions $ 209 268 Benefits paid (209) (268) Funded status at year end $ (1,386) (1,521) The assumptions used to develop the preceding information for post-retirement healthcare benefits are as follows: Years ended December 31, 2023 2022 2021 Discount rate 4.99 % 2.75 % 2.39 % Monthly cost of healthcare insurance per beneficiary (1) $ 916 415 343 Annual rate of increase in healthcare costs 5.00 % 5.00 % 5.00 % (1) Not in thousands. If the assumed rate of increase in healthcare costs was increased by one percentage point to 6% from the level presented above, the interest cost component of net periodic post-retirement healthcare benefit cost would increase by $3,300 and the accumulated post-retirement benefit obligation for healthcare benefits would increase by $66,200. The following table sets forth information for plans with an accumulated benefit obligation in excess of plan assets: December 31, 2023 2022 Projected benefit obligation $ 1,386 1,521 Accumulated benefit obligation 1,386 1,521 (c) Common Stock Awards On April 18, 2018, shareholders approved the Northwest Bancshares, Inc. 2018 Equity Incentive Plan with 1,500,000 common shares authorized for award. From this plan, we awarded employees 293,755 common shares and outside directors 27,000 common shares with a grant date fair value of $13.68 per share (total market value of $4.4 million at issuance) on May 25, 2021. Also during 2021, we awarded discretionary grants of 13,452 common shares with a weighted average grant date fair value of $13.76. During 2022, we awarded discretionary grants of 12,521 common shares with a weighted average grant date fair value of $13.98. These shares vest over a five On May 18, 2022, shareholders approved the Northwest Bancshares, Inc. 2022 Equity Incentive Plan with 3,500,000 shares authorized for award. From this plan we can awarded employees or directors restricted stock units (“RSUs”). The RSUs vest over a specified time period with the first vesting occurring one year from the grant date. We also award restricted stock awards (“RSAs”) which fully vest one-year from the grant date. We also award performance share units (“PSUs”). The number of PSUs earned will be based on attainment of certain performance criteria over a three-year period, with the actual number of shares issuable ranging between 0% and 150% of the number of PSUs granted. The PSUs have a three-year cliff vesting, from the date of grant, and any PSU’s earned will be issued after the vesting period. During the years ended December 31, 2022 and 2023, we granted the following awards (amounts in this table are not in thousands) : Year-ended Grant date Award to Shares Grant type Weighted average grant date fair value Total Vesting period December 31, 2022 5/18/2022 Employees 150,027 RSU $11.00 $1.7 million 3 years 5/18/2022 Employees 150,027 PSU 10.26 $1.5 million 3 years 5/18/2022 Directors 41,206 RSA 12.55 $517,000 1 year Various Employees 13,115 RSU 12.69 $166,000 3 years December 31, 2023 3/15/2023 Employees 176,623 RSU 11.28 $2.0 million 3 years 3/15/2023 Employees 176,623 PSU 10.54 $1.9 million 3 years 3/15/2023 Directors 33,048 RSA 12.80 $423,000 1 year 3/27/2023 Employees 80,980 RSU 11.20 $907,000 2 years Various Employees 128148 RSU 10.30 $1.3 million 3 years Total shares forfeited from the 2022 plan were 71,073 of which 44,791 shares were forfeited during the year ended December 31, 2023. At December 31, 2023, there was compensation expense of $4.0 million to be recognized for awarded but unvested RSUs and $1.8 million to be recognized for awarded but unvested PSUs, with an expense recognition period remaining of 2.5 years. At December 31, 2023, there was compensation expense of $88,000 to be recognized for awarded but unvested RSAs, with an expense recognition period remaining of one year. (d) Stock Option Plans The Northwest Bancshares, Inc. 2018 Equity Incentive Plan also authorized the granting of 3,500,000 stock options authorized for award. On May 25, 2021, we granted employees 621,972 stock options and outside directors 72,000 stock options with an exercise price of $13.68 per share. There were no stock options granted during the years-ended December 31, 2022 and December 31, 2023. These awarded stock options vest over a five-year period with the first vesting occurring on the grant date with a ten-year exercise period from the grant date. The following table summarizes the activity in our option plans during the years ended December 31, 2023, 2022 and 2021 (amounts in this table are not in thousands): Years ended December 31, 2023 2022 2021 Number Weighted average Number Weighted average Number Weighted average Balance at beginning of year 3,657,580 $ 14.25 4,380,310 $ 14.05 5,243,172 $ 13.72 Granted (1) — — — — 693,972 13.68 Exercised (2) (63,315) 11.46 (465,920) 12.14 (1,219,581) 12.28 Forfeited/expired (385,260) 13.80 (256,810) 14.64 (337,253) 14.59 Balance at end of year 3,209,005 14.36 3,657,580 14.25 4,380,310 14.05 Exercisable at end of year 2,601,367 14.52 2,556,235 14.43 2,618,733 14.15 (1) Weighted average fair value of options at grant date: N/A, N/A and $0.64, respectively.

Fair Value Disclosures [Abstract]
Disclosures About Fair Value of Financial Instruments	Disclosures About Fair Value of Financial Instruments We are required to disclose fair value information about financial instruments whether or not recognized in the Consolidated Statement of Financial Condition. Fair value information of certain financial instruments and all nonfinancial instruments is not required to be disclosed. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company. Financial assets and liabilities recognized or disclosed at fair value on a recurring basis and certain financial assets and liabilities on a non-recurring basis are accounted for using a three-level hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. This hierarchy gives the highest priority to quoted prices with readily available independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market inputs (Level 3). When various inputs for measurement fall within different levels of the fair value hierarchy, the lowest level input that has a significant impact on fair value measurement is used. Financial assets and liabilities are categorized based upon the following characteristics or inputs to the valuation techniques: • Level 1 - Financial assets and liabilities for which inputs are observable and are obtained from reliable quoted prices for identical assets or liabilities in actively traded markets. This is the most reliable fair value measurement and includes, for example, active exchange-traded equity securities. • Level 2 - Financial assets and liabilities for which values are based on quoted prices in markets that are not active or for which values are based on similar assets or liabilities that are actively traded. Level 2 also includes pricing models in which the inputs are corroborated by market data, for example, matrix pricing. • Level 3 - Financial assets and liabilities for which values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Level 3 inputs include the following: • Quotes from brokers or other external sources that are not considered binding; • Quotes from brokers or other external sources where it cannot be determined that market participants would in fact transact for the asset or liability at the quoted price; and • Quotes and other information from brokers or other external sources where the inputs are not deemed observable. We are responsible for the valuation process and as part of this process may use data from outside sources in establishing fair value. We perform due diligence to understand the inputs used or how the data was calculated or derived. We also corroborate the reasonableness of external inputs in the valuation process. The carrying amounts reported in the Consolidated Statement of Financial Condition approximate fair value for the following financial instruments: cash and cash equivalents, marketable securities available-for-sale, residential mortgage loans held-for-sale, accrued interest receivable, interest rate lock commitments, forward commitments, interest rate swaps, savings and checking deposits, foreign exchange swaps, risk participation agreements, and accrued interest payable. Marketable Securities Where available, market values are based on quoted market prices, dealer quotes, and prices obtained from independent pricing services. Debt securities — available-for-sale - Generally, debt securities are valued using pricing for similar securities, recently executed transactions and other pricing models utilizing observable inputs. The valuation for most debt securities is classified as Level 2. Securities within Level 2 include corporate bonds, municipal bonds, mortgage-backed securities and U.S. government obligations. Certain debt securities which were AAA rated at purchase do not have an active market, and as such we have used an alternative method to determine the fair value of these securities. The fair value has been determined using a discounted cash flow model using market assumptions, which generally include cash flow, collateral and other market assumptions. As such, securities which otherwise would have been classified as Level 2 securities if an active market for those assets or similar assets existed are included herein as Level 3 assets. Debt securities — held-to-maturity - The fair value of debt securities held-to-maturity is determined in the same manner as debt securities available-for-sale. Loans Receivable Loans with comparable characteristics including collateral and re-pricing structures are segregated for valuation purposes. Each loan pool is separately valued utilizing a discounted cash flow analysis. Projected monthly cash flows are discounted to present value using a market rate for comparable loans, which is not considered an exit price. Characteristics of comparable loans include remaining term, coupon interest, and estimated prepayment speeds. Delinquent loans are separately evaluated given the impact delinquency has on the projected future cash flow of the loan including the approximate discount or market rate, which is not considered an exit price. Loans Held-for-Sale The estimated fair value of loans held-for-sale is based on market bids obtained from potential buyers. FHLB Stock Due to the restrictions placed on the transferability of FHLB stock, it is not practical to determine the fair value. FHLB stock is recorded at cost. Deposit Liabilities The estimated fair value of deposits with no stated maturity, which includes demand deposits, money market, and other savings accounts, is the amount payable on demand. Although market premiums paid for depository institutions reflect an additional value for these low-cost deposits, adjusting fair value for any value expected to be derived from retaining those deposits for a future period of time or from the benefit that results from the ability to fund interest-earning assets with these deposit liabilities is prohibited. The fair value estimates of deposit liabilities do not include the benefit that results from the low-cost funding provided by these deposits compared to the cost of borrowing funds in the market. Fair values for time deposits are estimated using a discounted cash flow calculation that applies contractual cost currently being offered in the existing portfolio to current market rates being offered locally for deposits of similar remaining maturities. The valuation adjustment for the portfolio consists of the present value of the difference of these two cash flows, discounted at the assumed market rate of the corresponding maturity. Borrowed Funds Fixed rate advances are valued by comparing their contractual cost to the prevailing market cost. The carrying amount of repurchase agreements approximates their fair value. Subordinated Debentures The fair value of our subordinated debentures is calculated using the discounted cash flows at rates observable for other similarly traded liabilities. Junior Subordinated Debentures The fair value of junior subordinated debentures is calculated using the discounted cash flows at the prevailing rate of interest. Interest Rate Lock Commitments and Forward Commitments The fair value of interest rate lock commitments is based on the value of underlying loans held-for-sale which is based on quoted prices for similar loans in the secondary market. This value is then adjusted based on the probability of the loan closing (i.e., the “pull-through” amount, a significant unobservable input). The fair value of forward sale commitments is based on quoted prices from the secondary market based on the settlement date of the contracts. Cash Flow Hedges, Interest Rate and Foreign Exchange Swap Agreements and Risk Participation Agreements The fair value of interest rate swaps is based upon the present value of the expected future cash flows using the SOFR discount curve, the basis for the underlying interest rate. To price interest rate swaps, cash flows are first projected for each payment date using the fixed rate for the fixed side of the swap and the forward rates for the floating side of the swap. These swap cash flows are then discounted to time zero using SOFR zero-coupon interest rates. The sum of the present value of both legs is the fair market value of the interest rate swap. These valuations have been derived from our third party vendor’s proprietary models rather than actual market quotations. The proprietary models are based upon financial principles and assumptions that we believe to be reasonable. The fair value of the foreign exchange swap is derived from proprietary models rather than actual market quotations. The proprietary models are based upon financial principles and assumptions we believe to be reasonable. Risk participation agreements are entered into when Northwest purchases a portion of a commercial loan that has an interest rate swap. Northwest assumes credit risk on its portion of the interest rate swap should the borrower fail to pay as agreed. The value of risk participation agreements is determined based on the value of the swap after considering the credit quality, probability of default, and loss given default of the borrower. Off-Balance Sheet Financial Instruments These financial instruments generally are not sold or traded, and estimated fair values are not readily available. However, the fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements.

We classify loans individually assessed as nonrecurring Level 3. Mortgage servicing rights - Mortgage servicing rights represent the value of servicing residential mortgage loans, when the mortgage loans have been sold into the secondary market and the associated servicing has been retained. The value is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds and delinquency rate assumptions as inputs. All of these assumptions require a significant degree of management judgment. Servicing rights and the related mortgage loans are segregated into categories or homogeneous pools based upon common characteristics. Adjustments are only made when the estimated discounted future cash flows are less than the carrying value, as determined by individual pool. As such, mortgage servicing rights are classified as nonrecurring Level 3. Real Estate Owned - Real estate owned is comprised of property acquired through foreclosure or voluntarily conveyed by borrowers. These assets are recorded on the date acquired at the lower of the related loan balance or fair value, less estimated disposition costs, with the fair value being determined by appraisal. Subsequently, foreclosed assets are valued at the lower of the amount recorded at acquisition date or fair value, less estimated disposition costs. We classify real estate owned as nonrecurring Level 3. The following table presents additional quantitative information about assets measured at fair value on a recurring and nonrecurring basis and for which we have utilized Level 3 inputs to determine fair value at December 31, 2023: Fair value ($) Valuation Significant Range Loans individually assessed 36,747 Appraisal value (1) Estimated cost to sell 10% Mortgage servicing rights 133 Discounted cash flow Annual service cost $91 Prepayment rate 6.6% to 16.9% (10.0%) Expected life (months) 52.7 to 103.7 (74.8) Option adjusted spread 731 basis points Forward yield curve 5.46% to 5.38% Real estate owned, net 104 Appraisal value (1) Estimated cost to sell 15% Loans held for sale 8,768 Quoted prices for similar loans in active markets adjusted by an expected pull-through rate Estimated pull-through rate 100% (1) Fair value is generally determined through independent appraisals of the underlying collateral, which may include Level 3 inputs that are not identifiable.

Regulatory Capital Requirements

Regulatory Capital Requirements	12 Months Ended
	Dec. 31, 2023
Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Capital Requirements	Regulatory Capital Requirements We and our banking subsidiary are subject to various regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by the regulators that, if undertaken, could have a direct material effect on our financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices must be met. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Applicable regulations limit an organization’s capital distributions and certain discretionary bonus payments if the organization does not hold a “capital conservation buffer” consisting of 2.5% of Total Tier 1 and Common Equity Tier 1 (“CET1”) capital to risk-weighted assets in addition to the amount necessary to meet its minimum risk-based capital requirements. Quantitative measures established by regulation to ensure capital adequacy require us and our banking subsidiary to maintain minimum amounts and ratios (set forth in the table below) of Total, Tier 1, and CET1 capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier I capital to average assets (as defined). As of December 31, 2023 and 2022, we and our banking subsidiary exceeded all capital adequacy requirements to which we were subject. We have elected to phase the estimated impact of CECL into regulatory capital in accordance with the interim final rule of the Board of Governors of the Federal Reserve System (FRB) and other U.S. banking agencies that became effective on March 31, 2020. As a result, we delayed recognizing the estimated impact of CECL on regulatory capital until after a two-year deferral period, which for us extended through December 31, 2021. Beginning on January 1, 2022, we were required to phase in 75% of the previously deferred estimated capital impact of CECL, with 50% to be phased in at the beginning of 2023, and 25% at the beginning of 2024, until fully phased in by the first quarter of 2025. Under the interim final rule, the estimated impact of CECL on regulatory capital that we will defer and later phase in is calculated as the entire day-one impact at adoption plus 25% of the subsequent change in allowance during the two-year deferral period. As of December 15, 2023, the most recent assessment from FDIC, Northwest Bank exceeded all regulatory capital requirements and their regulatory capital ratios were above the minimum levels required to be considered “well-capitalized” for regulatory purposes . To be considered as “well capitalized,” Northwest Bank must maintain total risk-based, Tier 1 risk-based, CET 1 risk-based, and Tier 1 leverage ratios as set forth in the table. There are no conditions or events since that notification that management believes have changed the bank’s categories.

Legal Proceedings	Legal Proceedings We establish accruals for legal proceedings when information related to the loss contingencies represented by those matters indicates both that a loss is probable and that the amount of loss can be reasonably estimated. As of December 31, 2023, we do not anticipate that the aggregate ultimate liability arising out of any pending or threatened legal proceedings will be material to our Consolidated Financial Statements. Any such accruals are adjusted thereafter as appropriate to reflect changes in circumstances. Due to the inherent subjectivity of assessments and unpredictability of outcomes of legal proceedings, any amounts accrued may not represent the ultimate loss to us from legal proceedings.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments We are a party to derivative financial instruments in the normal course of business to manage our own exposure to fluctuations in interest rates and to meet the needs of our customers. The primary derivatives that we use are interest rate swaps and caps and foreign exchange contracts, which are entered into with counterparties that meet established credit standards. We believe that the credit risk inherent in all of our derivative contracts is minimal based on our credit standards and the netting and collateral provisions of the interest rate swap agreements. Derivatives Designated as Hedging Instruments As of December 31, 2023, the Company had entered into seven separate pay-fixed interest rate swaps in order to synthetically convert short-term three month FHLB advances to fixed-rate term funding with an aggregate value of $175 million with maturities ranging from three Derivatives and Hedging . Our cash flow hedges are recorded within other assets on the Consolidated Statement of Financial Condition at their estimated fair value. As long as the hedge remains highly effective, the changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. A hedging relationship that is determined to not be highly effective no longer qualifies for hedge accounting and any gain or loss is recognized immediately in earnings. Amounts reclassified into earnings are included in interest expense in the Consolidated Statement of Income. Derivatives Not Designated as Hedging Instruments We act as an interest rate or foreign exchange swap counterparty for certain commercial borrowers in the normal course of servicing our customers, which are accounted for at fair value. We manage our exposure to such interest rate or foreign exchange swaps by entering into corresponding and offsetting interest rate swaps with third parties that mirror the terms of the swaps we have with the commercial borrowers. These positions (referred to as “customer swaps”) directly offset each other and our exposure is the fair value of the derivatives due to changes in credit risk of our commercial borrowers and third parties. Customer swaps are recorded within other assets or other liabilities on the consolidated statement of financial condition at their estimated fair value. Changes to the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the Consolidated Statement of Income. We enter into interest rate lock commitments for residential mortgage loans which commit us to lend funds to a potential borrower at a specific interest rate within a specified period of time. Interest rate lock commitments that relate to the origination of mortgage loans that will be held-for-sale are considered derivative financial instruments under applicable accounting guidance. Interest rate lock commitments on loans held-for-sale are carried at fair value in other assets on the consolidated statement of financial condition. Northwest sells loans to the secondary market on a mandatory or best efforts basis. The loans sold on a mandatory basis commit us to deliver a specific principal amount of mortgage loans to an investor at a specified price, by a specified date, or the commitment must be paired off. These forward commitments entered into on a mandatory delivery basis meet the definition of a derivative financial instrument. All closed loans to be sold on a mandatory delivery basis are classified as held-for-sale on the Consolidated Statement of Financial Condition. Changes to the fair value of the interest rate lock commitments and the forward commitments are recorded in mortgage banking income in the Consolidated Statements of Income. We enter into risk participation agreements with financial institution counterparties for interest rate swaps related to loans in which we are a participant. The risk participation agreements provide credit protection to the financial institution should the borrower fail to perform on its interest rate derivative contract with the financial institution. These risk participation agreements are recorded within other liabilities on the Consolidated Statement of Financial Condition at their estimated fair value. Changes to the fair value of the the risk participation agreements are included in other operating income in the Consolidated Statement of Income.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations Northwest Bancshares, Inc., a Maryland corporation headquartered in Columbus, Ohio, is the b ank holding company for its wholly owned subsidiary, Northwest Bank. Northwest Bank, a Pennsylvania chartered savings bank, offers a complete line of business and personal banking products, as well as treasury management solutions and wealth management services through its 142 banking locations in Pennsylvania, New York, Ohio, and Indiana.
Principles of Consolidation	Principles of Consolidation The Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries after elimination of all intercompany accounts and transactions.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of the statements of financial condition and cash flows, cash and cash equivalents include cash and amounts due from banks, interest-bearing deposits in other financial institutions, federal funds sold, and other short-term investments with original maturities of three months or less.
Marketable Securities	Marketable Securities We classify marketable securities at the time of purchase as held-to-maturity, available-for-sale, or trading. Securities for which management has the intent and ability to hold until maturity are classified as held-to-maturity and are carried at cost, adjusted for amortization of premiums and accretion of discounts on a level yield basis (amortized cost). If it is management’s intent at the time of purchase to hold securities for an indefinite period of time and/or to use such securities as part of its asset/liability management strategy, the securities are classified as available-for-sale and are carried at fair value, with unrealized gains and losses reported as accumulated other comprehensive income/(loss), a separate component of shareholders’ equity, net of tax. Securities classified as available-for-sale include securities that may be sold in response to changes in interest rates, resultant prepayment risk, or other market factors. Securities that are bought and held principally for the purpose of selling them in the near term are classified as trading and are reported at fair value, with changes in fair value included in earnings. The cost of securities sold is determined on a specific identification basis. We held no securities classified as trading at or during the years ended December 31, 2023 and 2022. Fair values are determined as described in Note 16. Throughout the year we validate the prices received from third parties by comparing them to prices provided by a different independent pricing service. We have reviewed the detailed valuation methodologies provided to us by our pricing services. On a quarterly basis, we measure expected credit losses on held-to-maturity debt securities on a collective basis by major security type and all of our held-to-maturity debt securities are residential mortgage-backed securities. Accrued interest receivable on held-to-maturity debt securities total ed $2.5 million and $2.8 million at December 31, 2023 and December 31, 2022, respectively, and is excluded from estimated credit losses. All of our r esidential mortgage-backed securities are issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. For available-for-sale debt securities in an unrealized loss position, on at least a quarterly basis, we review our investments for impairment. An investment security is deemed impaired if the fair value of the investment is less than its amortized cost. We consider both our intent to sell and the likelihood that we will not have to sell the investment securities before recovery of their amortized cost basis during our evaluation. If we intend to sell the investment security or if it is more likely than not that we will be required to sell the investment security, the entire impairment is recorded in earnings. For available-for-sale debt securities that do not meet this criteria, we evaluate whether the decline in fair value has resulted from credit losses or other factors. In making this assessment we consider the issuer of the securities and their creditworthiness, any changes to the rating of the security and any adverse conditions specifically related to the security, among other factors. Also, we may evaluate the business and financial outlook of the issuer, as well as broader economic performance indicators. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than amortized cost. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when we believe the uncollectibility of an available-for-sale security is confirmed or when there is an intent or requirement to sell the security. Accrued interest receivable d $1.6 million and $2.0 million at December 31, 2023 and December 31, 2022, respectively , and is excluded from the estimate of credit losses. A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days past due. The receivable for interest income that is accrued but not collected is reversed against interest income when the debt security is placed on nonaccrual status. No debt securities were on nonaccrual status as of December 31, 2023 and December 31, 2022.
Loans Receivable	Loans Receivable Our portfolio segments are based on the class of financing receivable. Additionally, the class of financing receivables are based on several factors including the method for monitoring and assessing credit risk and the risk characteristics of the financing receivables. Based on evaluation of the nature of our financing receivables, along with the nature and extent of exposure to credit risk arising from these receivables, our portfolio segments were determined to be Personal Banking and Business Banking loans. • Personal Banking loans consist of the following classes of financing receivables: ◦ Residential mortgage loans - fixed and adjustable rate mortgage loans ◦ Home equity loans - first and second mortgage loans and home equity lines of credit ◦ Vehicle loans - direct and indirect automobile and motorcycle loans ◦ Consumer loans - unsecured lines of credit, credit card loans, and other consumer loans • Business Banking loans consist of the following classes of financing receivables: ◦ Commercial real estate - multi-family commercial real estate loans are secured by multi-family residences, such as rental properties and loans secured by nonresidential properties such as hotels, commercial offices, medical buildings, manufacturing facilities and retail establishments, excluding owner-occupied loans, and including small business commercial real estate loans ◦ Commercial real estate - owner-occupied loans - commercial real estate loans secured by residential or non-residential properties ◦ Commercial loans - other commercial loans, including small business commercial loans and equipment finance loans Loans are reported at amortized cost. Amortized cost is the principal balance outstanding, net of any deferred purchased premiums an d discounts, deferred origination fees or costs and the allowance for credit losses. Accrued interest receivable totaled $42.2 million and $30.4 million at December 31, 2023 and December 31, 2022, respectively, and was reported in accrued interest receivable on the Consolidated Statements of Financial Condition. Accrued interest receivable is excluded from the amortized cost basis of loans and from the estimate of allowance for credit losses. Interest income on loans is credited to income as earned. Interest earned on loans for which no payments were received during the month is accrued at month end. Generally, accrued interest on loans more than 90 days delinquent is reversed and such loans are placed on nonaccrual status, except for credit card loans which are not placed in nonaccrual status based on delinquency. All loans are placed on nonaccrual status when principal or interest is 90 days or more delinquent or when there is reasonable doubt that interest or principal will not be collected in accordance with the contractual terms. Interest receipts on all nonaccrual loans are recognized as interest income when it has been determined that all principal and interest will be collected or are applied to principal when collectability of contractual principal is in doubt. Nonaccrual loans generally are restored to an accrual basis when principal and interest become current and a period of performance has been established in accordance with the contractual terms, typically six months. Occasionally, the Company modifies loans to borrowers in financial distress by providing principal forgiveness, term extensions, an other-than-insignificant payment delay, or interest rate reduction. When principal forgiveness is provided, the amount of forgiveness is charged off against the allowance for credit losses. Loan delinquency is measured based on the number of days since the payment due date. Past due status is measured using the loan’s contractual maturity date. Personal Banking loans are charged-off or charged down when they become 180 da ys delinquent, unless the borrower has filed for bankruptcy. Business Banking loans are charged-off or charged down when, in our opinion, they are no longer collectible or when it has been determined that the collateral value no longer supports the carrying value of the loan for loans that are collateral dependent. Loan fees and certain direct loan origination costs are deferred and the net deferred fee or cost is then recognized using the level-yield method over the contractual life of the loan as an adjustment to interest income. We identify certain residential mortgage loans and small business administration guaranteed loans which will be sold prior to maturity, as loans held-for-sale. These loans are recorded at fair value less estimated cost to sell. At December 31, 2023 and 2022, there were $8.8 million and $9.9 million of loans classified as held-for-sale, respectively. Acquired loans that are not considered purchased with credit deterioration (“PCD”) are initially measured at fair value with no carryover of the related allowance for credit losses. Determining the fair value of the loans involves estimating the amount and timing of principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. Acquired loans may be classified as PCD loans upon acquisition if they have experienced more than insignificant credit deterioration since origination. Loans are considered to have experienced more than insignificant credit deterioration if they are greater than 30 days past due, classified special mention or worse or on nonaccrual status. An allowance for credit losses on day 1 is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The allowance is recognized on day 1 by adding it to the fair value of the loan, which is the “Day 1 amortized cost”. There is no credit loss expense recognized on PCD loans because the initial allowance is established by grossing-up the amortized cost of the PCD loan. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision expense.
Allowance for Credit Losses and Provision for Credit Losses	Allowance for Credit Losses and Provision for Credit Losses The allowance for credit losses is deducted from, or added to, the loan’s amortized cost basis to present the net amount expected to be collected on our lending portfolios. We estimate the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Loans are charged off against the allowance when we believe that a loan balance is confirmed to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Expected credit losses are estimated over the contractual term of the loans, adjusted for prepayments. The contractual term excludes expected extensions, renewals and modifications or the extension or renewal option is included in the contract and is not unconditionally cancellable by the Company. Credit card receivables do not have stated maturities. In determining the estimated life of a credit card receivable, we first estimate the future cash flows expected to be received and then apply those expected future cash flows to the credit card balance. The allowance for credit losses is measured on a collective (“pool”) basis when similar risk characteristics exist. For the purpose of calculating portfolio-level reserves, we have grouped our loans into seven segments: residential mortgage loans, home equity loans, vehicle loans, consumer loans, commercial real estate loans, commercial real estate owner-occupied and commercial loans. The allowance for credit losses is measured at the pool level utilizing loan-level inputs wherever possible. We use a twenty-four month forecasting period and revert to historical average loss rates thereafter. The reasonable and supportable forecast is based on a probability-weighted multiple macroeconomic forecast approach and obtained from a third party vendor. Reversion to the mean takes place over a twelve-month period. Our loss rate models utilize a linear reversion method. For our probability of default (“PD”)/loss given default (“LGD”) models we revert the PD utilizing exponential reversion, which is an accelerated method, and the LGD utilizing a linear reversion method. Historical average loss rates are calculated using historica l data beginning in 2009 through the current period. As part of the analysis as of December 31, 2023, we considered the most recent macroeconomic forecasts available. Mortgage and Home Equity Loans The allowance for credit losses within the mortgage and home equity loan pools is calculated using a non-discounted cash flow method through a PD, LGD, and prepayment model developed by an external third-party and adjusted for asset specific characteristics. These classes are further divided into smaller pools of loans with similar risk characteristics such as: lines versus loans, fixed versus variable, senior lien position versus junior lien position, among other things. For each pool, the models project default rates, prepayment rates, and severity rates. The models accept as inputs key risk drivers such as: current balance, original credit bureau score, original loan-to-value ratio, type of collateral, location of collateral, delinquency status, loan age, among other characteristics. They also utilize macroeconomic forecasts of home price indices, unemployment rates, gross domestic product, and others. Vehicle Loans The allowance for credit losses within the vehicle loan pool is calculated using a non-discounted cash flow model through a PD, LGD, and prepayment model developed by an external third-party and adjusted for asset specific risk characteristics. These classes are further divided into smaller pools of loans with similar risk characteristics such as: cars, trucks and powersport vehicles and recreational vehicles. Monthly probabilities of default and prepayments are estimated for each loan, along with estimates of exposure at default and loss given default. The model accepts as inputs key risk drivers such as loan, borrower, and collateral characteristics. It also uses macroeconomic forecasts of used car price indices, gross domestic product, unemployment rates and others. Consumer Loans The allowance for credit losses within the consumer loan portfolio is calculated at the portfolio-level using a non-discounted cash flow method through a suite of loss rate models developed internally with the assistance of an external third-party. This class of financing receivables is further divided into credit cards, unsecured lines of credit and other consumer loans. The allowance for credit losses for credit cards and unsecured lines of credit is calculated using two transition matrix models to project portfolio-level net charge-off rates. Both models use current balance and delinquency status as key risk drivers. These models are not natively sensitive to macroeconomic forecasts. The necessary adjustments to account for current and expected macroeconomic conditions is captured via our qualitative adjustment framework. For other consumer loans, a regression model is used to project portfolio-level net charge-off rates. This model uses borrower information and macroeconomic forecasts as key inputs. Commercial Real Estate Loans The commercial real estate loan class is further segmented into smaller pools of loans with similar risk characteristics, commercial real estate loans and small business commercial real estate loans. The allowance for credit losses for the commercial real estate loan portfolio is calculated at the pool level using a non-discounted cash flow method through a PD/LGD model developed by an external third-party. This model projects default and severity rates. The model accepts as inputs key risk drivers such as: current balance, original loan-to-value-ratio, type of collateral, location of collateral, delinquency status, loan age, obligor financial statement information, and expected prepayment rates, among other characteristics. It also utilizes macroeconomic forecasts of commercial real estate price indices, unemployment rates, gross domestic product and others. The allowance for credit losses for commercial real estate small business portfolio is calculated at a borrower-level with a PD/LGD model. Separate models were built by industry segment. Each model was built with a logistic regression model except for the U.S. Small Business Administration (SBA) and Agriculture sub-portfolios. For SBA, a portfolio-level fractional logit model was developed; the small Agriculture segment uses a simple long-run average loss rate. The LGD model is assumption-based and assigns varying LGDs by industry segment. The models ’ overall key inputs are borrower and collateral characteristics and macroeconomic forecasts including real GDP, unemployment, home price appreciation, and real disposable personal income. Commercial Loans and Commercial Real Estate - Owner Occupied Loans The commercial loan class is further segmented into smaller pools of loans with similar risk characteristics, commercial loans and commercial small business loans, including equipment finance loans. The allowance for credit losses for the commercial loan portfolio and the commercial real estate - owner occupied loan portfolio is calculated at the pool level using a non-discounted cash flow method through a PD/LGD model developed by an external third-party. The commercial loan portfolio and the commercial real estate owner occupied loan portfolio models project default and severity rates. The model accepts as inputs key risk drivers such as the obligor financial statement information, collateral type, the obligor’s primary industry, expected prepayment rates, among other characteristics. It also utilizes macroeconomic forecasts of unemployment rates, gross domestic product, corporate bond spreads, and others. The allowance for credit losses for commercial small business loans is calculated at a borrower-level with a PD/LGD model. Separate models were built by industry segment. Each model was built with a logistic regression model except for the U.S. Small Business Administration (SBA) and Agriculture sub-portfolios. For SBA, a portfolio-level fractional logit model was developed; the small Agriculture segment uses a simple long-run average loss rate. The LGD model is assumption-based and assigns varying LGDs by industry segment. The models ’ overall key inputs are borrower and collateral characteristics and macroeconomic forecasts including real GDP, unemployment, home price appreciation, and real disposable personal income. Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not also included in the collective evaluation. When we determine that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs. If this criteria is not met, a discounted cash flow method is used to determine the allowance for credit losses. All changes in the discounted cash flow method over time are reported in the allowance for credit losses. The allowance calculation is also supplemented with qualitative reserves that takes into consideration the current portfolio and specific risk characteristics, such as changes in underwriting standards, portfolio mix, delinquency level, or term, as well as changes in environmental conditions, among other factors, that have occurred but are not yet reflected in the quantitative model component. The modifications to borrowers experiencing financial distress are included in their respective portfolio segment and the current loan balance and updated loan terms are run through their respective allowance models to arrive at the quantitative portion of the allowance for credit losses. Subsequent performance of the loans will be measured by delinquency status and will be captured through our models or our qualitative factor assessment, as deemed appropriate. If we no longer believe the loan demonstrates similar risks to their respective portfolio segment, an individual assessment will be performed. Upon the Company’s determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount.
Real Estate Owned	Real Estate Owned Real estate owned is comprised of property either acquired through foreclosure or voluntarily conveyed by borrowers. These assets are recorded on the date acquired at the lower of the loan balance or fair value of the collateral, less estimated disposition costs, with the fair value being determined by an appraisal. Any initial write-down is charged to the allowance for credit losses. Subsequently, foreclosed assets are valued at the lower of the amount recorded at acquisition date or the current fair value, less estimated disposition costs. Any subsequent write-down or gains or losses realized from the disposition of such property are credited or charged to noninterest income.
Restricted Investment in FHLB Stock	Restricted Investment in FHLB Stock Federal law requires a member institution of the FHLB system to hold stock of its district FHLB according to a predetermined formula. FHLB stock is carried at cost and evaluated for impairment based on the ultimate recoverability of the par value. FHLB stock can only be purchased, redeemed and transferred at par value. Dividends are reported in interest income in the Consolidated Statements of Income.
Premises and Equipment	Premises and Equipment Premises and equipment are carried at cost, less accumulated depreciation and amortization. Depreciation is accumulated on a straight-line basis over the estimated useful lives of the related assets. Estimated lives range from three . Amortization of leasehold improvements is accumulated on a straight-line basis over the terms of the related leases or the useful lives of the related assets, whichever is shorter.
Goodwill	Goodwill Goodwill is generated from the premium paid for an acquisition and is allocated to reporting units, which are either our reportable segments or one level below. Reporting units are identified based upon analyzing each individual operating segment. A reporting unit is defined as a distinct, separately identifiable component of an operating segment for which complete, discrete financial information is available that management regularly reviews. Goodwill is not subject to amortization but is tested for impairment at least annually and possibly more frequently if certain events occur or changes in circumstances arise. In testing goodwill for impairment, we have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, after assessing all events and circumstances, we determine it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the two-step impairment test would be unnecessary. However, if we conclude otherwise, it would then be required to perform the first step of the goodwill impairment test and continue to the second step, if necessary. Step 1 requires the fair value of each reporting unit be compared to its carrying amount, including goodwill. Determining the fair value of a reporting unit requires a high degree of subjective judgment, including developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions and selecting an appropriate control premium. We have established June 30 of each year as the date for conducting our annual goodwill impairment assessment. Quarterly, we evaluate if there are any triggering events that would require an update to our previous assessment. We conducted our annual impairment assessment as o f June 30, 2023 b y first performing a qualitative assessment of goodwill to determine if it was more likely than not that the fair value was less than the carrying value. In performing a qualitative analysis, factors considered include, but are not limited to, macroeconomic conditions, industry and market conditions and overall financial performance. The results of the qualitative assessme nt for 2023 i ndicated that it was not more likely than not that the fair value of the reporting unit was less than the carrying value. Consequently, no additional quantitative impairment test was required and no impairment was recorded in 2023. Future events could cause us to conclude that goodwill has become impaired, which would result in recording an impairment loss. There were no events or changes in circumstance in our operations that would cause us to update the assessment performed as of June 30, 2023 and 2022. Accordingly, we have determined that goodwill is not impaired as of December 31, 2023 and 2022.
Core Deposit and Other Identifiable Intangibles	Core Deposit and Other Identifiable Intangibles Through the assistance of an independent third party, we analyze and prepare a core deposit study for all bank acquisitions or other identifiable intangible asset study, such as customer lists, for all non-bank acquisitions. The core deposit study reflects the cumulative present value benefit of acquiring deposits versus an alternative source of funding. The other identifiable intangible asset study reflects the cumulative present value benefit of acquiring the income stream from an existing customer base versus developing new business relationships. Based upon analysis, the amount of the premium related to the core deposits or other identifiable intangibles of the business purchased is calculated along with the estimated life of the intangible. The intangible, which is recorded in other intangible assets, is then amortized to expense on an accelerated basis over an approximate life of typically betwe en seven
Bank-Owned Life Insurance	Bank-Owned Life Insurance We own insurance on the lives of a certain group of current and former employees and directors. The policies were purchased to help offset the increase in the costs of various benefit plans, including healthcare, as well as the directors deferred compensation plan. The cash surrender value of these policies is included as an asset on the Consolidated Statements of Financial Condition and any increases in the cash surrender value are recorded as tax-free noninterest income on the Consolidated Statements of Income. In the event of the death of an insured individual covered by these policies, after distribution to the insured’s beneficiaries, if any, we receive a tax-free death benefit, which is recorded as noninterest income.
Deposits	Deposits Interest on deposits is accrued and charged to expense monthly and is paid or credited in accordance with the terms of the accounts.
Revenue Recognition	Revenue Recognition Revenue that is not associated with our financial assets and financial liabilities is recognized when performance obligations under the terms of a contract with our customers are satisfied. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. The majority of our revenue continues to be recognized at the point in time when the services are provided to our customers.
Pension Plans	Pension Plans We maintain multiple noncontributory defined benefit pension plans (“Pension Plan”) for substantially all of our employees. The net periodic pension cost has been calculated using service cost, interest cost, expected returns on plan assets and net amortization. The other components of the net periodic benefit cost are included in other expense on the Consolidated Statement of Income and are reported separately from the service costs. Pension expense and obligations depend on assumptions used in calculating such amounts. These assumptions include discount rates, anticipated salary increases, interest costs, expected return on plan assets, mortality rates, and other factors. In determining the projected benefit obligations for pension benefits at December 31, 2023 and 2022, we u sed a discount rate of 4.79% and 4.99%, respectively. We use the FTSE (previously Citigroup) Pension Liability Index rates matching the duration of our benefit payments as of the measurement date, December 31, to determine the discount rate.
Income Taxes	Income Taxes We join with our wholly owned subsidiaries in filing a consolidated federal income tax return. In accordance with an intercompany tax allocation agreement, the applicable federal income tax expense or benefit is allocated to each subsidiary based upon taxable income or loss calculated on a separate company basis. Each subsidiary is responsible for payment of its own federal income tax liability or receives reimbursement of federal income tax benefit. In addition, deferred taxes are calculated and maintained on a separate company basis.
Stock-Related Compensation	Stock-Related Compensation Stock-based compensation awards granted, comprised of performance and time-based restricted stock units, stock options, and restricted stock awards, are valued at fair value and compensation cost is recognized on a straight-line basis over the requisite service or performance period of each award. For service-based awards compensation will be recognized pro rata over the periods in which the shares vest. F or performance-based awards, compensation expense is recognized evenly over the performance period, based on the probability of the achievements of the performance conditions set forth in the plans. Forfeitures are recognized as they occur. For restricted stock awards, the recipients are entitled to all shareholder rights, except that the shares may not be sold, pledged, or otherwise disposed of and are required to be held in a trust. For restricted stock units and performance stock units, the recipients are not entitled to any of the shareholder rights. We determine the fair value of each option award, estimated on the grant date, using the Black-Scholes-Merton option-pricing model. The Black-Scholes-Merton option-pricing model uses variables including expected volatilities, expected term, risk-free discount rate and annual rate of quarterly dividends. Expected volatilities are based on historical volatility of the Company’s stock. The expected terms are based upon actual exercise and forfeiture experience of previous option grants. The risk-free rate is based on yields on U.S. Treasury securities of a similar maturity to the expected term of the options. During the years ended December 31, 2023 and 2022 we awarded no stock options to employees or directors. New shares are issued when options are exercised. Option awards are generally granted with an exercise price equal to the closing market price of the Company’s stock on the day before the grant date.
Derivative Financial Instruments	Derivative Financial Instruments We recognize all derivative financial instruments as either assets or liabilities in the balance sheet and measure those instruments at fair value. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. To qualify for hedge accounting rules, a hedging relationship must be highly effective in offsetting the risk designation as being hedge. The hedging relationship must be formally documented at inception and assess the hedging relationship at least on a quarterly basis to ensure the hedging instrument continues to be highly effective over the life of the hedging relationship. Those methods must be consistent with our approach to managing risk. At times, we utilize interest rate swap agreements as part of the management of interest rate risk to hedge the interest rate risk on floating rate borrowings. Amounts receivable or payable are recognized as accrued under the terms of the agreements and the differential is recorded as an adjustment to interest expense. The interest rate swaps are designated as cash flo w hedges, with the derivative’s unrealized gain or loss recorded as a component of other comprehensive income which is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. A hedging relationship that is determined to not be highly effective no longer qualifies for hedge accounting and must be de-designated. Any gain or loss is recognized immediately in earnings. We act as an interest rate or foreign exchange swap counterparty for certain commercial borrowers in the normal course of servicing our customers, which are accounted for at fair value. We manage our exposure to such interest rate or foreign exchange swaps by entering into corresponding and offsetting interest rate swaps with third parties that mirror the terms of the swaps we have with the commercial borrowers. These positions (referred to as “customer swaps”) directly offset each other and our exposure is the fair value of the derivatives due to changes in credit risk of our commercial borrowers and third parties. Customer swaps are recorded within other assets or other liabilities on the consolidated statement of financial condition at their estimated fair value. Changes to the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the Consolidated Statement of Income.
Off-Balance-Sheet Instruments	Off-Balance-Sheet Instruments In the normal course of business, we extend credit in the form of loan commitments, undisbursed lines of credit, and standby letters of credit. These off-balance-sheet instruments involve, to various degrees, elements of credit and interest rate risk not reported in the Consolidated Statements of Financial Condition. We utilize the same underwriting standards for these instruments as other extensions of credit.
Leases	Leases At inception, the Company determines if an arrangement contains a lease and whether that lease meets the classification of a finance or operating lease. Operating lease right of use (“ROU ” ) assets represent our right to use an underlying asset during the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments. ROU assets are further adjusted for lease incentives and initial direct costs. The Company has operating leases for certain branch and office facilities or land with lease terms up to 35 years. These leases generally contain renewal options for periods ranging from one . These options are included in the lease term when it is reasonably certain that the options will be exercised. Some of the Company’s lease arrangements contain lease components (e.g., minimum rent payments) and non-lease components (e.g., common area maintenance, taxes, etc.). For all leases, the Company elected the option of not separating lease and non-lease components and instead we account for them as a single lease component. Certain lease agreements include rental payments that are adjusted periodically for an index or rate. The leases are initially measured using the projected adjustment for the index or rate in effect at the commencement date. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.
Use of Estimates	Use of Estimates The preparation of financial statements, in conformity with accounting principles generally accepted in the United States of America, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amount of revenues and expenses during the reporting period. The estimate and assumptions that we deem important to our financial statements relate to the allowance for credit losses. This estim ate and assumptions are based on management’s best estimates and judgment and we evaluate them using historical experience and other factors, including the current economic environment. We adjust our estimates and assumptions when facts and circumstances dictate. As future events cannot be determined, actual results could differ significantly from our estimates.
Reclassification of Prior Years' Statements	Reclassification of Prior Years’ Statements Certain items previously reported have been reclassified to conform with the current year’s reporting format. These reclassifications had no effect on the reported results of operations. An adjustment has been made to the Consolidated Statements of Income and Consolidated Statements of Cash Flows for the years ended December 31, 2022 and December 31, 2021, to reclassify the provision for credit losses - unfunded commitments, previously presented in other expense, to provide additional transparency to financial statement users.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosure.” This ASU eliminates the accounting guidance for troubled debt restructurings (“TDRs”), while enhancing disclosure requirements for certain loan modifications when a borrower is experiencing financial difficulty. This ASU also requires the disclosure of current period gross write-offs by year for origination for financing receivables. This guidance is effective for annual periods beginning after December 15, 2022, including interim periods within those years, with early adoption permitted. This ASU is applied prospectively to modifications and write-offs beginning on the first day of the fiscal year of adoption. An entity may elect to adopt a modified retrospective transition method on the recognition and measurement of the TDR guidance. We adopted ASU 2022-02 using a modified retrospective transition approach related to the recognition and measurement of the TDR guidance and on a prospective basis for modification and write-offs. As a result, the Company was not required to adjust its comparative period financial information for effects of the standard or make the new required ASU 2022-02 disclosure for periods before the date of adoption (i.e. January 1, 2023). This change did not have a material effect on our consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This ASU provides temporary optional guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The guidance provides expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. The amendments primarily include contract modifications and hedge accounting, as well as providing a one-time election for the sale or transfer of debt securities classified as held-to-maturity. This guidance was effective 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 to Topic 848”. This guidance extends the guidance of ASU 2022-04 from December 31, 2022 to December 31, 2024. In January 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform.” This ASU provides amendments, which are elective, and apply to all entities that have derivative instruments that use an interest rate for margining, discounting or contract price alignment of certain derivative instruments that are modified as a result of the reference rate reform. This ASU is effective upon issuance through December 31, 2024, and can be adopted at any time during this period.

When principal forgiveness is provided, the amount of forgiveness is charged off against the allowance for credit losses. In some cases, the Company provides multiple types of concessions to one loan. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as principal forgiveness, may be granted. For loans included in the “combination” columns below, multiple types of modifications have been made on the same loan within the current reporting period. The combination is at least two of the following: a term extension, principal forgiveness, an other-than-insignificant payment delay, and/or an interest rate reduction. The following table presents the amortized cost basis of loans as of December 31, 2023 that were both experiencing financial difficulty and modified during the periods indicated, by class and by type of modification. The percentage of the amortized cost basis of loans that were modified to borrowers in financial distress as compared to the amortized cost basis of each class of financial receivable is also presented below (dollars in thousands).
