NOTES TO FINANCIAL STATEMENTS
1. Significant accounting policies

The consolidated interim financial statements of the Company were compiled in accordance with GAAP using the accounting policies set forth in note 1 of Notes to Financial Statements included in M&T's 2023 Annual Report, except as described in the following table. The financial statements contain all adjustments which are, in the opinion of management, necessary for a fair statement of the Company's financial position, results of operations and cash flows for the interim periods presented.
Recent accounting developments
Standard Description
Required date
of adoption
Effect on consolidated financial statements
Standards Adopted in 2024
Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method The amendments permit an election to account for tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met.

Under the proportional amortization method, the initial cost of the investment is amortized in proportion to the income tax credits and other income tax benefits received and the net amortization and income tax credits and other income tax benefits are recognized in the income statement as a component of income tax expense (benefit). 		January 1, 2024 As described in note 12, the Company adopted the amended guidance effective January 1, 2024 using a modified retrospective transition. The guidance did not have a material impact on the Company's consolidated financial statements.
2. Divestiture
On April 29, 2023, the Company sold its CIT business to a private equity firm. The transaction resulted in a pre-tax gain of $ 225 million ($ 157 million after-tax effect) that has been included in "other revenues from operations" in the Consolidated Statement of Income for the nine months ended September 30, 2023. Prior to the sale, the CIT business contributed $ 60 million to trust income in the nine months ended September 30, 2023. After considering expenses, the results of operations from the CIT business were not material to the Company's consolidated results of operations in that period.

Credit quality indicators
The Company utilizes a loan grading system to differentiate risk amongst its commercial and industrial loans and commercial real estate loans. Loans with a lower expectation of default are assigned one of ten possible “pass” loan grades and are generally ascribed lower loss factors when determining the allowance for credit losses. Loans with an elevated level of credit risk are designated as “criticized” and are ascribed a higher loss factor when determining the allowance for credit losses. Criticized loans may be designated as “nonaccrual” if the Company no longer expects to collect all amounts according to the contractual terms of the loan agreement or the loan is delinquent 90 days or more.
Line of business personnel in different geographic locations with support from and review by the Company’s credit risk personnel review and reassign loan grades based on their detailed knowledge of individual borrowers and their judgment of the impact on such borrowers resulting from changing conditions in their respective regions. Factors considered in assigning loan grades include borrower-specific information related to expected future cash flows and operating results, collateral values, geographic location, financial condition and performance, payment status, and other information. The Company’s policy is that at least annually, updated financial information be obtained from commercial borrowers associated with pass grade loans and additional analysis performed. On a quarterly basis, the Company’s credit personnel review criticized commercial and industrial loans and commercial real estate loans greater than $ 5 million to determine the appropriateness of the assigned loan grade, including whether the loan should be reported as accruing or nonaccruing.

4. Loans and leases and the allowance for credit losses, continued
Despite the allocation in the preceding tables, the allowance for credit losses is general in nature and is available to absorb losses from any loan or lease type. In determining the allowance for credit losses, accruing loans with similar risk characteristics are generally evaluated collectively. The Company utilizes statistically developed models to project principal balances over the remaining contractual lives of the loan portfolios and to determine estimated credit losses through a reasonable and supportable forecast period. Individual loan credit quality indicators, including loan grade and borrower repayment performance, can inform the models, which have been statistically developed based on historical correlations of credit losses with prevailing economic metrics, including unemployment, GDP and real estate prices. Model forecasts may be adjusted for inherent limitations or biases that have been identified through independent validation and back-testing of model performance to actual realized results. At each of September 30, 2024 and December 31, 2023, the Company utilized a reasonable and supportable forecast period of two years. Subsequent to this forecast period the Company reverted, ratably over a one-year period, to historical loss experience to inform its estimate of losses for the remaining contractual life of each portfolio.
The Company also estimates losses attributable to specific troubled credits identified through both normal and targeted credit review processes. The amounts of specific loss components in the Company’s loan and lease portfolios are determined through a loan-by-loan analysis of larger balance commercial and industrial loans and commercial real estate loans that are in nonaccrual status. Such loss estimates are typically based on expected future cash flows, collateral values and other factors that may impact the borrower’s ability to pay. To the extent that those loans are collateral-dependent, they are evaluated based on the fair value of the loan’s collateral as estimated at or near the financial statement date. As the quality of a loan deteriorates to the point of designating the loan as “criticized,” the process of obtaining updated collateral valuation information is usually initiated, unless it is not considered warranted given factors such as the relative size of the loan, the characteristics of the collateral or the age of the last valuation. In those cases where current appraisals may not yet be available, prior appraisals are utilized with adjustments, as deemed necessary, for estimates of subsequent declines in values as determined by line of business and/or loan workout personnel. Those adjustments are reviewed and assessed for reasonableness by the Company’s credit risk personnel. Accordingly, for real estate collateral securing larger nonaccrual commercial and industrial loans and commercial real estate loans, estimated collateral values are based on current appraisals and estimates of value. For non-real estate loans, collateral is assigned a discounted estimated liquidation value and, depending on the nature of the collateral, is verified through field exams or other procedures. In assessing collateral, real estate and non-real estate values are reduced by an estimate of selling costs.
For residential real estate loans, including home equity loans and lines of credit, the excess of the loan balance over the net realizable value of the property collateralizing the loan is charged-off when the loan becomes 150 days delinquent. That charge-off is based on recent indications of value from external parties that are generally obtained shortly after a loan becomes nonaccrual. Loans to consumers that file for bankruptcy are generally charged-off to estimated net collateral value shortly after the Company is notified of such filings. When evaluating individual home equity loans and lines of credit for charge-off and for purposes of estimating losses in determining the allowance for credit losses, the Company gives consideration to the required repayment of any first lien positions related to collateral property. Other consumer loans are generally charged-off when the loans are 91 to 180 days past due, depending on whether the loan is collateralized and the status of repossession activities with respect to such collateral.
Changes in the amount of the allowance for credit losses reflect the outcome of the procedures described herein, including the impact of changes in macroeconomic forecasts as compared with previous forecasts, as well as the impact of portfolio concentrations, imprecision in economic forecasts, geopolitical conditions and other risk factors that might influence the loss estimation process.
The Company’s reserve for off-balance sheet credit exposures was not material at September 30, 2024 and December 31, 2023.

11. Derivative financial instruments
As part of managing interest rate risk, the Company enters into interest rate swap agreements to modify the repricing characteristics of certain portions of the Company’s portfolios of earning assets and interest-bearing liabilities. The Company designates interest rate swap agreements utilized in the management of interest rate risk as either fair value hedges or cash flow hedges. Interest rate swap agreements are generally entered into with counterparties that meet established credit standards and most contain master netting, collateral and/or settlement provisions protecting the at-risk party. Based on adherence to the Company’s credit standards and the presence of the netting, collateral or settlement provisions, the Company believes that the credit risk inherent in these contracts was not material as of September 30, 2024. Information about interest rate swap agreements entered into for interest rate risk management purposes summarized by type of financial instrument the swap agreements were intended to hedge follows:

(a) Certain clearinghouse exchanges consider payments by counterparties for variation margin on derivative instruments to be settlements of those positions. The impact of such payments for interest rate swap agreements designated as fair value hedges was a net settlement of gains of $ 15 million at September 30, 2024 and of losses of $ 43 million at December 31, 2023. The impact of such payments on interest rate swap agreements designated as cash flow hedges was a net settlement of gains of $ 89 million at September 30, 2024 and of losses of $ 214 million at December 31, 2023.
(b) Under the terms of these agreements, the Company receives settlement amounts at a fixed rate and pays at a variable rate.
(c) Under the terms of these agreements, the Company receives settlement amounts at a variable rate and pays at a fixed rate.
(d) Includes notional amount and terms of $ 1.9 billion of forward-starting interest rate swap agreements that become effective in 2025.
(e) Includes notional amount and terms of $ 6.6 billion of forward-starting interest rate swap agreements that become effective in 2024, 2025 and 2026.
(f) Includes notional amount and terms of $ 1.0 billion of forward-starting interest rate swap agreements that become effective in 2025.
(g) Includes notional amount and terms of $ 9.0 billion of forward-starting interest rate swap agreements that become effective in 2024.
The Company utilizes commitments to sell residential and commercial real estate loans to hedge the exposure to changes in the fair value of real estate loans held for sale. Such commitments have generally been designated as fair value hedges. The Company also utilizes commitments to sell real estate loans to offset the exposure to changes in the fair value of certain commitments to originate real estate loans for sale. Changes in unrealized gains and losses as a result of those activities were not material in each of the three and nine months ended September 30, 2024 and 2023. Such changes are included in mortgage banking revenues and, in general are realized in subsequent periods as the related loans are sold and commitments satisfied.
Other derivative financial instruments not designated as hedging instruments included interest rate contracts, foreign exchange and other option and futures contracts. Interest rate contracts not designated as hedging instruments had notional values of $ 42.5 billion and $ 44.4 billion at September 30, 2024 and December 31, 2023, respectively. The notional amounts of foreign exchange and other option and futures contracts not designated as hedging instruments aggregated $ 1.4 billion and $ 1.5 billion at September 30, 2024 and December 31, 2023, respectively.

The net effect of interest rate swap agreements was to decrease net interest income by $ 115 million and $ 328 million during the three-month and nine-month periods ended September 30, 2024, respectively, and to decrease net interest income by $ 79 million and $ 211 million during the three-month and nine-month periods ended September 30, 2023, respectively. The amount of interest income recognized in the Consolidated Statement of Income associated with derivatives designated as cash flow hedges was a decrease of $ 102 million and $ 65 million for the three months ended September 30, 2024 and 2023, respectively, and a decrease of $ 288 million and $ 173 million for the nine months ended September 30, 2024 and 2023, respectively. As of September 30, 2024, the unrealized net gain recognized in other comprehensive income related to cash flow hedges was $ 59 million, of which losses of $ 78 million, gains of $ 48 million and $ 90 million, and losses of $ 1 million relate to interest rate swap agreements maturing in 2025, 2026, 2027 and 2028 respectively.
The Company does not offset derivative asset and liability positions in its consolidated financial statements. The Company’s exposure to credit risk by entering into derivative contracts is mitigated through master netting agreements and collateral posting or settlement requirements. Master netting agreements covering interest rate and foreign exchange contracts with the same party include a right to set-off that becomes enforceable in the event of default, early termination or under other specific conditions.
The aggregate fair value of derivative financial instruments in a liability position, which are subject to enforceable master netting arrangements and the related collateral posted, was not material at each of September 30, 2024 and December 31, 2023. Certain of the Company’s derivative financial instruments contain provisions that require the Company to maintain specific credit ratings from credit rating agencies to avoid higher collateral posting requirements. If the Company’s debt ratings were to fall below specified ratings, the counterparties of the derivative financial instruments could demand immediate incremental collateralization on those instruments in a net liability

position. The aggregate fair value of all derivative financial instruments with such credit risk-related contingent features in a net liability position at September 30, 2024 was not material.
The aggregate fair value of derivative financial instruments in an asset position with counterparties, which are subject to enforceable master netting arrangements, was $ 94 million at September 30, 2024 and $ 179 million at December 31, 2023. Counterparties posted collateral relating to those positions of $ 87 million at September 30, 2024 and $ 179 million at December 31, 2023. Interest rate swap agreements entered into with customers are subject to the Company’s credit risk standards and often contain collateral provisions.
In addition to the derivative contracts noted above, the Company clears certain derivative transactions through a clearinghouse, rather than directly with counterparties. Those transactions cleared through a clearinghouse require initial margin collateral and variation margin payments depending on the contracts being in a net asset or liability position. The amount of initial margin collateral posted by the Company was $ 154 million and $ 129 million at September 30, 2024 and December 31, 2023, respectively. The fair value asset and liability amounts of derivative contracts have been reduced by variation margin payments treated as settlements as described herein. Variation margin on derivative contracts not treated as settlements continues to represent collateral posted or received by the Company.
12. Variable interest entities and asset securitizations
The Company’s securitization activity includes securitizing loans originated for sale into government issued or guaranteed mortgage-backed securities. The Company has not recognized any material losses as a result of having securitized assets.
In March 2024, M&T Bank issued asset-backed notes secured by automobile loans. Approximately $ 526 million of such loans were sold into a special purpose trust which in turn issued asset-backed notes to investors. The loans continue to be serviced by the Company. A total of $ 511 million of such notes, representing the senior-most notes in the securitization, were purchased by third parties. Those asset-backed notes had a weighted-average estimated life of approximately two years and a weighted-average interest rate of 5.29 % at the time of securitization. Additionally, $ 15 million of certificates representing the residual interests of the trust were retained by the Company. As a result of the retention of the residual interests and its continued role as servicer of the loans, the Company is considered to be the primary beneficiary of the securitization trust and, accordingly, the trust has been included in the Company's consolidated financial statements. At September 30, 2024, the remaining balance of the loans and leases in trust was $ 418 million and the outstanding asset-backed notes issued to third party investors was $ 406 million.
In August 2024, M&T Bank issued asset-backed notes secured by equipment finance loans and leases. Approximately $ 790 million of such loans were sold into a special purpose trust which in turn issued asset-backed notes to investors. The loans and leases continue to be serviced by the Company. A total of $ 650 million of such notes, representing the senior-most notes in the securitization, were purchased by third parties. Those asset-backed notes had a weighted-average estimated life of approximately two years and a weighted-average interest rate of 4.87 % at the time of securitization. Additionally, $ 140 million of credit enhancement in the form of equity interest and reserve accounts were provided by the Company. As a result of the retention of credit risk and its continued role as servicer of the loans, the Company is considered to be the primary beneficiary of the securitization trust and, accordingly, the trust has been included in the Company's consolidated financial statements. At September 30, 2024, the remaining balance of the loans and leases in trust was $ 742 million and the outstanding asset-backed notes issued to third party investors was $ 614 million.
M&T has issued junior subordinated debentures payable to various trusts that have issued preferred capital securities. M&T owns the common securities of those trust entities. The Company is not considered to be the primary beneficiary of those entities and, accordingly, the trusts are not included in the Company’s consolidated financial statements. At each of September 30, 2024 and December 31, 2023, the Company included the junior subordinated debentures as “long-term borrowings” in its Consolidated Balance Sheet and recognized $ 22 million in other assets for its “investment” in the common securities of the trusts that will be concomitantly repaid to M&T by the

respective trust from the proceeds of M&T’s repayment of the junior subordinated debentures associated with preferred capital securities.
The Company has invested as a limited partner in various partnerships that collectively had total assets of approximately $ 10.0 billion and $ 9.8 billion at September 30, 2024 and December 31, 2023, respectively. Those partnerships generally construct or acquire properties, including properties and facilities that produce renewable energy, for which the investing partners are eligible to receive certain federal income tax credits in accordance with government guidelines. Such investments may also provide tax deductible losses to the partners. The partnership investments also assist the Company in achieving its community reinvestment initiatives. The Company, in its position as limited partner, does not direct the activities that most significantly impact the economic performance of the partnerships and, therefore, the partnership entities are not included in the Company's consolidated financial statements. The Company’s investments in qualified affordable housing projects are accounted for using the proportional amortization method whereby those investments are amortized to "income taxes" in the Consolidated Statement of Income as tax credits and other tax benefits resulting from deductible losses associated with the projects are received. Effective January 1, 2024, the Company adopted amended guidance which permits an election to account for other tax equity investments using the proportional amortization method if certain conditions are met. The Company has elected to apply the proportional amortization method to eligible renewable energy and certain other tax credit investments in addition to the low income housing tax credit investments for which the proportional amortization method had previously been applied. Information on the Company's carrying amount of its investments in tax equity partnerships and its related future funding commitments are presented in the following table:
(Dollars in millions) September 30, 2024 December 31, 2023
Affordable housing projects:

The reduction to income tax expense recognized from the Company's investments in partnerships accounted for using the proportional amortization method was $ 10 million (net of $ 47 million of investment amortization) and $ 6 million (net of $ 46 million of investment amortization) for the three months ended September 30, 2024 and 2023, respectively, and $ 25 million (net of $ 135 million of investment amortization) and $ 22 million (net of $ 128 million of investment amortization) for the nine months ended September 30, 2024 and 2023, respectively. The net reduction to income tax expense has been reported in "net change in other accrued income and expense" in the Consolidated Statement of Cash Flows. While the Company has elected to apply the proportional amortization method for renewable energy credit investments, at September 30, 2024 no such investments met the eligibility criteria for application of that method. The reduction to income tax expense recognized from renewable energy credit investments was $ 8 million and $ 28 million for the three-month and nine-month periods ended September 30, 2024, respectively, and $ 10 million and $ 22 million for the three-month and nine-month periods ended September 30, 2023, respectively. As a limited partner, there is no recourse to the Company by creditors of the partnerships. However, the tax credits that result from the Company’s investments in such partnerships are generally subject to recapture should a partnership fail to comply with the respective government regulations. The Company has not provided financial or other support to the partnerships that was not contractually required. Although the Company

currently estimates that no material losses are probable, its maximum exposure to loss from its investments in such partnerships as of September 30, 2024 was $ 2.1 billion, including possible recapture of certain tax credits.
The Company serves as investment advisor for certain registered money-market funds. The Company has no explicit arrangement to provide support to those funds, but may waive portions of its allowable management fees as a result of market conditions.
13. Fair value measurements
GAAP permits an entity to choose to measure eligible financial instruments and other items at fair value. The Company has not made any fair value elections at September 30, 2024.
Pursuant to GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level hierarchy exists in GAAP for fair value measurements based upon the inputs to the valuation of an asset or liability.
• Level 1 — Valuation is based on quoted prices in active markets for identical assets and liabilities.
• Level 2 — Valuation is determined from quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar instruments in markets that are not active or by model-based techniques in which all significant inputs are observable in the market.
• Level 3 — Valuation is derived from model-based and other techniques in which at least one significant input is unobservable and which may be based on the Company's own estimates about the assumptions that market participants would use to value the asset or liability.
When available, the Company attempts to use quoted market prices in active markets to determine fair value and classifies such items as Level 1 or Level 2. If quoted market prices in active markets are not available, fair value is often determined using model-based techniques incorporating various assumptions including interest rates, prepayment speeds and credit losses. Assets and liabilities valued using model-based techniques are classified as either Level 2 or Level 3, depending on the lowest level classification of an input that is considered significant to the overall valuation. The following is a description of the valuation methodologies used for the Company's assets and liabilities that are measured on a recurring basis at estimated fair value.
Trading account
Mutual funds held in connection with deferred compensation and other arrangements have been classified as Level 1 valuations. Valuations of investments in debt securities can generally be obtained through reference to quoted prices in less active markets for the same or similar securities or through model-based techniques in which all significant inputs are observable and, therefore, such valuations have been classified as Level 2.
Available-for-sale investment securities and equity securities
The Company's available-for-sale investment securities have generally been valued by reference to prices for similar securities or through model-based techniques in which all significant inputs are observable and, therefore, such valuations have been classified as Level 2. Certain investments in mutual funds and equity securities are actively traded and, therefore, have been classified as Level 1 valuations.
Real estate loans held for sale
The Company utilizes commitments to sell real estate loans to hedge the exposure to changes in fair value of real estate loans held for sale. The carrying value of hedged real estate loans held for sale includes changes in estimated fair value during the hedge period. Typically, the Company attempts to hedge real estate loans held for sale from the date of close through the sale date. The fair value of hedged real estate loans held for sale is generally calculated by reference to quoted prices in secondary markets for commitments to sell real estate loans with similar characteristics and, accordingly, such loans have been classified as a Level 2 valuation.

Commitments to originate real estate loans for sale and commitments to sell real estate loans
The Company enters into various commitments to originate real estate loans for sale and commitments to sell real estate loans. Such commitments are accounted for as derivative financial instruments and, therefore, are carried at estimated fair value on the Consolidated Balance Sheet. The estimated fair values of such commitments were generally calculated by reference to quoted prices in secondary markets for commitments to sell real estate loans to certain government-sponsored entities and other parties. The fair valuations of commitments to sell real estate loans generally result in a Level 2 classification. The estimated fair value of commitments to originate real estate loans for sale are adjusted to reflect the Company's anticipated commitment expirations. The estimated commitment expirations are considered significant unobservable inputs contributing to the Level 3 classification of commitments to originate real estate loans for sale. Significant unobservable inputs used in the determination of estimated fair value of commitments to originate real estate loans for sale are included in the accompanying table of significant unobservable inputs to Level 3 measurements.
Interest rate swap agreements used for interest rate risk management
The Company utilizes interest rate swap agreements as part of the management of interest rate risk to modify the repricing characteristics of certain portions of its portfolios of earning assets and interest-bearing liabilities. The Company generally determines the fair value of its interest rate swap agreements using externally developed pricing models based on market observable inputs and, therefore, classifies such valuations as Level 2. The Company has considered counterparty credit risk in the valuation of its interest rate swap agreement assets and has considered its own credit risk in the valuation of its interest rate swap agreement liabilities.
Other non-hedging derivatives
Other non-hedging derivatives consist primarily of interest rate contracts and foreign exchange contracts with customers who require such services with offsetting positions with third parties to minimize the Company's risk with respect to such transactions. The Company generally determines the fair value of its other non-hedging derivative assets and liabilities using externally developed pricing models based on market observable inputs and, therefore, classifies such valuations as Level 2.

The Company is required, on a nonrecurring basis, to adjust the carrying value of certain assets or provide valuation allowances related to certain assets using fair value measurements. The more significant of those assets follow.
Loans
Loans are generally not recorded at fair value on a recurring basis. Periodically, the Company records nonrecurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectable portions of those loans. Nonrecurring adjustments also include certain impairment amounts for collateral-dependent loans when establishing the allowance for credit losses. Such amounts are generally based on the fair value of the underlying collateral supporting the loan and, as a result, the carrying value of the loan less the calculated valuation amount does not necessarily represent the fair value of the loan. Real estate collateral is typically valued using appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace and the related nonrecurring fair value measurement adjustments have been classified as Level 2, unless significant adjustments have been made to the valuation that are not readily observable by market participants. Non-real estate collateral supporting commercial and industrial loans generally consists of business assets such as receivables, inventory and equipment. Fair value estimations are typically determined by discounting recorded values of those assets to reflect estimated net realizable value considering specific borrower facts and circumstances and the experience of credit personnel in their dealings with similar borrower collateral liquidations. Such discounts were in the range of 10 % to 90 % with a weighted-average of 37 % at September 30, 2024. As these discounts are not readily observable and are considered significant, the valuations have been classified as Level 3. Automobile collateral is typically valued by reference to independent pricing sources based on recent sales transactions of similar vehicles and, accordingly, the related nonrecurring fair value measurement adjustments have been classified as Level 2. Collateral values for other consumer installment loans are generally estimated based on historical recovery rates for similar types of loans which at September 30, 2024 was 43 %. As these recovery rates are not readily observable by market participants, such valuation adjustments have been classified as Level 3. Loans subject to nonrecurring fair value measurement were $ 805 million at September 30, 2024 ($ 159 million and $ 646 million of which were classified as Level 2 and Level 3, respectively), $ 923 million at December 31, 2023 ($ 234 million and $ 689 million of which were classified as Level 2 and Level 3, respectively) and $ 804 million at September 30, 2023 ($ 316 million and $ 488 million of which were classified as Level 2 and Level 3, respectively). Changes in the fair value recognized for partial charge-offs of loans and loan impairment reserves on loans held by the Company on September 30, 2024 were decreases of $ 81 million and $ 204 million for the three-month and nine-month periods ended September 30, 2024, respectively. Changes in the fair value recognized for partial charge-offs of loans and loan impairment reserves on loans held by the Company on September 30, 2023 were decreases of $ 116 million and $ 269 million for the three-month and nine-month periods ended September 30, 2023, respectively.
Assets taken in foreclosure of defaulted loans
Assets taken in foreclosure of defaulted loans are primarily comprised of commercial and residential real property and are generally measured at the lower of cost or fair value less costs to sell. The fair value of the real property is generally determined using appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace and the related nonrecurring fair value measurement adjustments have generally been classified as Level 2. Assets taken into foreclosure of defaulted loans subject to nonrecurring fair value measurement were not material at each of September 30, 2024 and 2023. Changes in fair value recognized for those foreclosed assets held by the Company were not material during the three-month and nine-month periods ended September 30, 2024 and 2023.

Capitalized servicing rights
Capitalized servicing rights are initially measured at fair value in the Company’s Consolidated Balance Sheet. The Company utilizes the amortization method to subsequently measure its capitalized servicing assets. In accordance with GAAP, the Company must record impairment charges, on a nonrecurring basis, when the carrying value of certain strata exceed their estimated fair value. To estimate the fair value of servicing rights, the Company considers market prices for similar assets, if available, and the present value of expected future cash flows associated with the servicing rights calculated using assumptions that market participants would use in estimating future servicing income and expense. Such assumptions include estimates of the cost of servicing loans, loan default rates, an appropriate discount rate and prepayment speeds. For purposes of evaluating and measuring impairment of capitalized servicing rights, the Company stratifies such assets based on the predominant risk characteristics of the underlying financial instruments that are expected to have the most impact on projected prepayments, cost of servicing and other factors affecting future cash flows associated with the servicing rights. Such factors may include financial asset or loan type, note rate and term. The amount of impairment recognized is the amount by which the carrying value of the capitalized servicing rights for a stratum exceed estimated fair value. Impairment is recognized through a valuation allowance. The determination of fair value of capitalized servicing rights is considered a Level 3 valuation. Capitalized servicing rights related to residential mortgage loans required no valuation allowance at each of September 30, 2024, December 31, 2023 and September 30, 2023.

With the exception of marketable securities and mortgage loans originated for sale, the Company’s financial instruments presented in the preceding tables are not readily marketable and market prices do not exist. The Company, in attempting to comply with the provisions of GAAP that require disclosures of fair value of financial instruments, has not attempted to market its financial instruments to potential buyers, if any exist. Since negotiated prices in illiquid markets depend greatly upon the then present motivations of the buyer and seller, it is reasonable to assume that actual sales prices could vary widely from any estimate of fair value made without the benefit of negotiations. Additionally, changes in market interest rates can dramatically impact the value of financial instruments in a short period of time.
The Company does not believe that the estimated information presented herein is representative of the earnings power or value of the Company. The preceding analysis, which is inherently limited in depicting fair value, also does not consider any value associated with existing customer relationships nor the ability of the Company to create value through loan origination, deposit gathering or fee generating activities. Many of the estimates presented herein are based upon the use of highly subjective information and assumptions and, accordingly, the results may not be precise. Management believes that fair value estimates may not be comparable between financial institutions due to the wide range of permitted valuation techniques and numerous estimates which must be made. Furthermore, because the disclosed fair value amounts were estimated as of the balance sheet date, the amounts actually realized or paid upon maturity or settlement of the various financial instruments could be significantly different.
14. Commitments and contingencies
In the normal course of business, various commitments and contingent liabilities are outstanding. The following table presents the Company's significant commitments. Certain of these commitments are not included in the Company's Consolidated Balance Sheet.
(Dollars in millions) September 30,
2024 		December 31,
2023
Commitments to extend credit:
Commercial and industrial $ 30,210 $ 28,566
Commercial real estate loans to be sold 825 916
Other commercial real estate 3,153 5,019
Residential real estate loans to be sold 258 163
Other residential real estate 744 331
Home equity lines of credit 7,950 8,109
Credit cards 5,889 5,578
Other 271 413
Standby letters of credit 2,267 2,289
Commercial letters of credit 70 62
Financial guarantees and indemnification contracts 4,090 4,036
Commitments to sell real estate loans 1,940 1,400
Commitments to extend credit are agreements to lend to customers, generally having fixed expiration dates or other termination clauses that may require payment of a fee. In addition to the amounts in the preceding table, the Company had discretionary funding commitments to commercial customers of $ 12.7 billion and $ 12.3 billion at September 30, 2024 and December 31, 2023, respectively, that the Company had the unconditional right to cancel prior to funding. Standby and commercial letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party, whereas commercial letters of credit are issued to facilitate commerce and typically result in the commitment being funded when the underlying transaction is consummated between the customer and a third party. The credit risk associated with commitments to extend credit and standby and commercial letters of credit is essentially the same as that involved with extending loans to customers and is subject to normal credit policies. Collateral may be obtained based on management's assessment of the customer's creditworthiness.

Financial guarantees and indemnification contracts are predominantly comprised of recourse obligations associated with sold loans and other guarantees and commitments. Included in financial guarantees and indemnification contracts are loan principal amounts sold with recourse in conjunction with the Company's involvement in the Fannie Mae DUS program. The Company's maximum credit risk for recourse associated with loans sold under this program totaled approximately $ 3.9 billion at each of September 30, 2024 and December 31, 2023. At September 30, 2024, the Company estimated that the recourse obligations described above were not material to the Company's consolidated financial position. There have been no material losses incurred as a result of those credit recourse arrangements.
Since many loan commitments, standby letters of credit, and guarantees and indemnification contracts expire without being funded in whole or in part, the contract amounts are not necessarily indicative of future cash flows.
The Company utilizes commitments to sell real estate loans to hedge exposure to changes in the fair value of real estate loans held for sale. Such commitments are accounted for as derivatives and along with commitments to originate real estate loans to be held for sale are recorded in the Consolidated Balance Sheet at estimated fair market value.
The Company is contractually obligated to repurchase previously sold residential real estate loans that do not ultimately meet investor sale criteria related to underwriting procedures or loan documentation. When required to do so, the Company may reimburse loan purchasers for losses incurred or may repurchase certain loans. The Company reduces residential mortgage banking revenues by an estimate for losses related to its obligations to loan purchasers. The amount of those charges is based on the volume of loans sold, the level of reimbursement requests received from loan purchasers and estimates of losses that may be associated with previously sold loans. At September 30, 2024, the Company's estimated obligation to loan purchasers was not material to the Company’s consolidated financial position.
M&T and its subsidiaries are subject in the normal course of business to various pending and threatened legal proceedings and other matters in which claims for monetary damages are asserted. On an on-going basis management, after consultation with legal counsel, assesses the Company’s liabilities and contingencies in connection with such proceedings. For those matters where it is probable that the Company will incur losses and the amounts of the losses can be reasonably estimated, the Company records an expense and corresponding liability in its consolidated financial statements. To the extent pending or threatened litigation could result in exposure in excess of that liability, the amount of such excess is not currently estimable. Although not considered probable, the range of reasonably possible losses for such matters in the aggregate, beyond the existing recorded liability, was between $ 0 and $ 25 million as of September 30, 2024. Although the Company does not believe that the outcome of pending legal matters will be material to the Company’s consolidated financial position, it cannot rule out the possibility that such outcomes will be material to the consolidated results of operations for a particular reporting period in the future.
In 2024, the FDIC notified member banks that the loss estimate attributable to certain failed banks had increased. The Company recorded FDIC special assessment expense of $ 34 million in the Consolidated Statement of Income for the nine months ended September 30, 2024 in addition to the $ 197 million recorded in the fourth quarter of 2023. The FDIC has indicated that the amount of the special assessment will be adjusted as its loss estimates change.

15. Segment information
Reportable segments have been determined based upon the Company's organizational structure and its internal profitability reporting system, which is organized by strategic business unit. The reportable segments are Commercial Bank, Retail Bank and Institutional Services and Wealth Management.
The financial information of the Company's segments was compiled utilizing the accounting policies described in note 23 of Notes to Financial Statements in the Company's 2023 Annual Report. The management accounting policies and processes utilized in compiling segment financial information are highly subjective and, unlike financial accounting, are not based on authoritative guidance similar to GAAP. As a result, the financial information of the reported segments is not necessarily comparable with similar information reported by other financial institutions. Furthermore, changes in management structure or allocation methodologies and procedures may result in changes in reported segment financial data.

16. Relationship with BLG and Bayview Financial
M&T holds a 20 % minority interest in BLG, a privately-held commercial mortgage company. That investment had no remaining carrying value at September 30, 2024 as a result of cumulative losses recognized and cash distributions received in prior years. Cash distributions now received from BLG are recognized as income by M&T and included in "other revenues from operations" in the Consolidated Statement of Income. That income totaled $ 25 million and $ 20 million for the nine-month periods ended September 30, 2024 and 2023, respectively. There were no cash distributions during the three-month periods ended September 30, 2024 and 2023.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
This Management's Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the consolidated financial statements and other information included in this Quarterly Report on Form 10-Q as well as with M&T's 2023 Annual Report. Information regarding the Company's business, its supervision and regulation and potential risks and uncertainties that may affect the Company's business, financial condition, liquidity and results of operations are also included in M&T's 2023 Annual Report.
As described in note 1 of Notes to Financial Statements in M&T's 2023 Annual Report, certain financial reporting changes became effective in the fourth quarter of 2023. Prior periods have been presented in conformity with the new classifications.
Overview
The Company's results of operations improved in the third quarter of 2024 as compared with the second quarter of 2024 reflecting a decline in provision for credit losses, higher other income and a modest increase in net interest income. Following four FOMC federal funds target interest rate increases totaling 100 basis points in the first three quarters of 2023, interest rates remained elevated resulting in higher deposit and borrowing costs which adversely impacted net interest income for the nine months ended September 30, 2024 as compared with the similar 2023 period. Those costs have since stabilized. In September 2024, the FOMC decreased the federal funds target interest rate by 50 basis points. That interest rate reduction had little impact on the Company's results of operations for the three and nine months ended September 30, 2024. Other income in the first nine months of 2023 included a $225 million gain on the sale of the Company's CIT business in April 2023. A summary of financial results for the Company is provided below:

____________________________________________
(a) Net interest income data are presented on a taxable-equivalent basis which is a non-GAAP measure. The taxable-equivalent adjustment represents additional income taxes that would be due if all interest income were subject to income taxes. This adjustment, which is related to interest received on qualified municipal securities, industrial revenue financings and preferred equity securities, is based on a composite income tax rate of approximately 25%.

- 45 -

The increase in net income in the recent quarter as compared with the second quarter of 2024 resulted from the following:
• Net interest income on a taxable-equivalent basis increased slightly reflecting an expansion of the net interest margin by 3 basis points as the cost of interest-bearing liabilities decreased while yields on earning assets remained unchanged from the immediately preceding quarter.
• Provision for credit losses declined $30 million reflecting a decrease in criticized commercial real estate and commercial and industrial loans, partially offset by commercial and industrial and consumer loan growth.
• Other income increased $22 million reflecting an increase in service charges on deposit accounts, favorable trading account and other non-hedging derivative gains and lower losses on bank investment securities.
The decline in net income for the nine months ended September 30, 2024 as compared with the same 2023 period reflects the following:
• Net interest income on a taxable-equivalent basis declined $272 million reflecting a narrowing of the net interest margin by 33 basis points as higher deposit and borrowing costs outpaced increased yields on the Company's earning assets.
• Provision for credit losses increased $50 million reflecting the impact of higher interest rates on the performance of commercial borrowers and loan growth.
• Other income in the first nine months of 2024 declined $180 million as compared with the first nine months of 2023 reflecting the sale of the CIT business in April 2023, partially offset by higher service charges on deposit accounts and a rise in residential mortgage banking revenues.
• Other expense in the first nine months of 2024, excluding $34 million of FDIC special assessment expense, rose $32 million from the similar 2023 period. Those higher expenses included an increase in salaries and employee benefits expense and outside data processing and software costs, partially offset by lower professional and other services expense and other costs of operations.
The Company's effective income tax rates were 20.7% and 23.4% for the quarters ended September 30, 2024 and June 30, 2024, respectively, and 21.5% and 24.5% for the nine-month periods ended September 30, 2024 and 2023, respectively. The recent quarter income tax expense reflects a $14 million discrete tax benefit related to certain tax credits claimed on a prior year income tax return. The first quarter of 2024 income tax expense reflects a $17 million net discrete tax benefit related to the resolution of an income tax matter inherited from the acquisition of People's United. Each of the discrete income tax benefits noted herein contributed to the lower effective income tax rate for the nine-month period ended September 30, 2024 as compared with the nine-month period ended September 30, 2023.
On August 15, 2024, M&T redeemed all 350,000 outstanding shares of its Perpetual Fixed-to-Floating Rate Non-Cumulative Preferred Stock, Series E, for $350 million. On May 13, 2024, M&T issued 75,000 shares of Perpetual Non-Cumulative Preferred Stock, Series J, with a liquidation preference of $10,000 per share. Additional information about the issued and outstanding preferred stock of M&T is included in note 6 of Notes to Financial Statements.
M&T repurchased 1,190,054 shares of its common stock in accordance with its capital plan during the recent quarter at an average cost per share of $166.40 resulting in a total cost, including the share repurchase excise tax, of $200 million. No share repurchases occurred in the first or second quarter of 2024. During the first nine months of 2023, M&T repurchased 3,838,157 shares of its common stock at an average cost per share of $154.76 resulting in a total cost, including the share repurchase excise tax, of $600 million.

Supplemental Reporting of Non-GAAP Results of Operations
M&T consistently provides supplemental reporting of its results on a “net operating” or “tangible” basis, from which M&T excludes the after-tax effect of amortization of core deposit and other intangible assets (and the related goodwill, core deposit intangible and other intangible asset balances, net of applicable deferred tax amounts) and gains (when realized) and expenses (when incurred) associated with merging acquired operations into the Company, since such items are considered by management to be “nonoperating” in nature. Although “net operating income” as defined by M&T is not a GAAP measure, M&T’s management believes that this information helps investors understand the effect of acquisition activity in reported results.

The efficiency ratio measures the relationship of noninterest operating expenses, which exclude expenses M&T considers to be "nonoperating" in nature consisting of amortization of core deposit and other intangible assets and merger-related expenses, to revenues. The calculations of the Company’s efficiency ratio, or noninterest operating expenses divided by the sum of taxable-equivalent net interest income and noninterest income (exclusive of gains and losses from bank investment securities), and reconciliations of GAAP amounts with corresponding non-GAAP amounts are presented in Table 2.

Taxable-equivalent Net Interest Income
Interest income earned on certain of the Company's assets is exempt from federal income tax. Taxable-equivalent net interest income is a non-GAAP measure that adjusts income earned on a tax-exempt asset to present it on an equivalent basis to interest income earned on a fully taxable asset. The Company's average balance sheets accompanied by the annualized taxable-equivalent interest income and expense and the average rate on the Company's earning assets and interest-bearing liabilities are presented as follows.

Expressed on a taxable-equivalent basis net interest income was $1.74 billion in the third quarter of 2024, compared with $1.73 billion in the second quarter of 2024. The $8 million increase in taxable-equivalent net interest income in the recent quarter reflects a 3 basis-point expansion of the net interest margin, or taxable-equivalent net interest income expressed as an annualized percentage of average earning assets, from the second quarter of 2024 to 3.62% in the recent quarter. That expansion reflects a stable yield on earning assets as higher yields on investment securities offset a decline in the yield on interest-bearing deposits at the FRB of New York, and a decrease in the cost of interest-bearing liabilities reflecting reduced funding levels from short-term borrowings and brokered time deposits. The Company continues to adjust its funding sources in consideration of the changing interest rate environment as well as the competitive landscape for customer deposits. Average brokered deposits and average short-term

borrowings declined by $1.1 billion or 9% and $928 million or 19%, respectively, when comparing the recent quarter with the second quarter of 2024.
Taxable-equivalent net interest income in the first nine months of 2024 was $5.16 billion, compared with $5.43 billion in the corresponding 2023 period. That decrease reflects a 33 basis-point narrowing of the net interest margin to 3.58% in the 2024 period from 3.91% in the year-earlier period as higher rates paid on interest-bearing liabilities outpaced an increase in yields on earning assets. An increase in average interest-bearing liabilities in the first nine months of 2024 as compared with the first nine months of 2023 reflected a shift in customer deposits toward higher cost interest-bearing products, including time deposits, and higher average brokered deposits and borrowings. Average interest-bearing deposits rose $11.6 billion or 11% in the first nine months of 2024 as compared with the first nine months of 2023 and included an increase in average brokered deposits of $1.5 billion or 14%. Average borrowings rose $2.9 billion or 22% when comparing the first nine months of 2024 with the same 2023 period. The increase in average earning assets in the first nine months of 2024 reflects higher average deposits at the FRB of New York, purchases of investment securities and loan growth.
Lending activities
The Company's lending activities in 2023 and for the first nine months of 2024 reflect its execution of various strategies to reduce its relative concentration of commercial real estate loans. The following table summarizes average loans and leases for the three-month and nine-month periods ended September 30, 2024 and percentage changes in the major components of the portfolio.

Average loans and leases totaled $134.8 billion in the third quarter of 2024, up nominally from the second quarter of 2024.
• Average commercial and industrial loans and leases were $59.8 billion in the recent quarter, up $1.6 billion from the second quarter of 2024, reflecting growth that spanned most industry types.
• Commercial real estate loans averaged $29.1 billion in the third quarter of 2024, down $2.4 billion from the second quarter of 2024, reflecting decreases of $1.9 billion and $472 million of average permanent and construction commercial real estate loans, respectively.
• Average consumer loans in the third quarter of 2024 increased $931 million from the second quarter of 2024 to $22.9 billion. That growth reflects an increase in average balances of recreational finance loans and automobile loans of $633 million and $255 million, respectively.
In the first nine months of 2024, average loans and leases totaled $134.4 billion, up $1.7 billion or 1%, from $132.7 billion in the corresponding 2023 period.
• Average commercial and industrial loans and leases in the first nine months of 2024 increased $4.4 billion from the similar 2023 period, reflecting growth across most industries, predominantly lending to the services and the financial and insurance industries and to motor vehicle and recreational finance dealers.
- 50 -

• Average commercial real estate loans declined $3.8 billion in the first nine months of 2024 as compared with the corresponding 2023 period reflecting decreases of $2.7 billion in average permanent commercial real estate loans and $1.1 billion in average construction loans.
• Average residential real estate loans decreased $662 million in the nine months ended September 30, 2024 from the first nine months of 2023. That decrease was largely attributable to customer payments on loans held for investment.
• Average consumer loans in the first nine months of 2024 increased $1.7 billion from the first nine months of 2023. That growth reflected higher average balances of recreational finance and automobile loans of $1.7 billion and $205 million, respectively, partially offset by a decline in the average balance of home equity loans and lines of credit of $251 million.
Investing activities
The investment securities portfolio averaged $31.0 billion in the third quarter of 2024, up $1.3 billion from the second quarter of 2024. That increase reflects the purchase of $4.0 billion of U.S. Treasury securities and government issued or guaranteed commercial and residential mortgage-backed securities in the recent quarter. In the first nine months of 2024 and 2023, investment securities averaged $29.8 billion and $28.1 billion, respectively. The rise in average balances in the first nine months of 2024 as compared with the similar 2023 period reflects purchases of U.S Treasury securities and government issued or guaranteed commercial and residential mortgage-backed securities of $11.2 billion during the first nine months of 2024. The Company sold $71 million of non-agency investment securities from its available-for-sale portfolio during the first nine months of 2024. There were no significant sales of investment securities during the nine months ended September 30, 2023. The Company routinely adjusts its holdings of capital stock of the FHLB of New York and the FRB of New York based on amounts of outstanding borrowings and available lines of credit with those entities.
The investment securities portfolio is largely comprised of government issued or guaranteed commercial and residential mortgage-backed securities and U.S. Treasury securities, but also includes municipal and other securities. When purchasing investment securities, the Company considers its liquidity position and its overall interest rate risk profile as well as the adequacy of expected returns relative to risks assumed, including prepayments. The Company may occasionally sell investment securities as a result of movements in interest rates and spreads, changes in liquidity needs, actual or anticipated prepayments, credit risk associated with a particular security, or as a result of restructuring its investment securities portfolio in connection with a business combination. The amounts of investment securities held by the Company are influenced by such factors as available yield in comparison with alternative investments, demand for loans, which generally yield more than investment securities, ongoing repayments, the levels of deposits, and management of liquidity and balance sheet size and resulting capital ratios.
The Company regularly reviews its debt investment securities for declines in value below amortized cost that might be indicative of credit-related losses. In light of such reviews, there were no credit-related losses on debt investment securities recognized in each of the nine months ended September 30, 2024 and 2023. A further discussion of fair values of investment securities is included herein under the heading "Capital." Additional information about the investment securities portfolio is included in notes 3 and 13 of Notes to Financial Statements.
Other earning assets include interest-bearing deposits at banks and trading account assets. Those other earning assets in the aggregate averaged $25.6 billion in the recent quarter, compared with $29.4 billion during the three months ended June 30, 2024, and $28.6 billion in the nine months ended September 30, 2024, compared with $25.0 billion in the nine months ended September 30, 2023. The amounts of other earning assets at those respective dates were predominantly comprised of deposits held at the FRB of New York. In general, the levels of those deposits often fluctuate due to changes in deposits of retail and commercial customers, trust-related deposits, brokered deposits and additions to or maturities of investment securities or borrowings.

Funding activities - deposits
The most significant source of funding for the Company is core deposits. The Company considers noninterest-bearing deposits, interest-bearing transaction accounts, savings deposits and time deposits of $250,000 or less as core deposits. The Company’s branch network is its principal source of core deposits, which generally carry lower interest rates than wholesale funds of comparable maturities. Average core deposits represented 77% and 76% of average earning assets for the quarters ended September 30, 2024 and June 30, 2024, respectively, and 77% and 80% for the nine months ended September 30, 2024 and 2023, respectively. The Company also includes brokered deposits as a component of its wholesale funding strategy. Depending on market conditions, including demand by customers and other investors, and the cost of funds available from alternative sources, the Company may change the amount or composition of brokered deposits in the future. The following table provides an analysis of changes in the components of average deposits.

Deposits averaged $161.5 billion in the recent quarter, a $2.0 billion decrease from $163.5 billion in the second quarter of 2024.
• Average core deposits decreased modestly when compared with the second quarter of 2024 and reflected a shift in customer funds from noninterest-bearing accounts and time deposits to savings and interest-checking accounts.
• The decrease in average brokered deposits in the recent quarter reflects a continued shift in the Company's wholesale funding strategy. Average brokered time deposits decreased 45% to $2.1 billion in the recent quarter from $3.8 billion in the second quarter of 2024. The rates paid on those deposits averaged 4.87% and 4.99% during the three months ended September 30, 2024 and June 30, 2024, respectively. Average brokered savings and interest-checking accounts increased 8% to $8.8 billion in the recent quarter from $8.2 billion in the second quarter of 2024. The rates paid on those deposits averaged 4.65% and 4.75% during the three months ended September 30, 2024 and June 30, 2024, respectively. The rate paid on total non-brokered interest-bearing deposits during the three months ended September 30, 2024 was 2.68%, up nominally from 2.67% for the quarter ended June 30, 2024, reflecting a stabilization in non-brokered deposit product pricing in 2024.
Average deposits increased $1.8 billion in the first nine months of 2024 from $161.2 billion in the corresponding 2023 period.
• Average core deposits decreased $1.1 billion in the nine months ended September 30, 2024 as compared with the similar 2023 period reflecting the impact of an elevated interest rate environment that influenced customers to seek higher rate alternatives, including a shift of funds to certain commercial sweep products and time deposits greater than $250,000.

• The increase in average brokered deposits in the nine months ended September 30, 2024 as compared with the first nine months of 2023 reflects the Company's liquidity management and funding strategies during a period of rising interest rates, partially offset by the maturity of some brokered time deposits in the recent nine-month period. Average brokered time deposits decreased $2.9 billion to $3.7 billion in the first nine months of 2024 from $6.6 billion in the nine months ended September 30, 2023 and the rates paid on those deposits averaged 4.98% and 4.95%, respectively. Average brokered savings and interest-checking accounts increased $4.4 billion to $8.4 billion in the nine months ended September 30, 2024 from $3.9 billion in the nine months ended September 30, 2023 and the rates paid on those deposits averaged 4.72% and 3.94%, respectively. The rate paid on total non-brokered interest-bearing deposits was 2.68% in the first nine months of 2024, compared with 1.74% in the similar 2023 period. That increase in the rate on non-brokered interest-bearing deposits reflected repricing on certain deposit products as customers sought higher yields in an elevated interest rate environment.
The accompanying table summarizes the components of average total deposits by reportable segment for the three months ended September 30, 2024 and June 30, 2024 and the nine months ended September 30, 2024 and 2023.

The Company uses borrowing capacity from banks, the FHLBs, the FRB of New York and others as sources of funding. Short-term borrowings represent arrangements that at the time they were entered into had a contractual maturity of one year or less. The lower levels of short-term borrowings in the third quarter of 2024 as compared with the second quarter of 2024 as well as for the nine months ended September 30, 2024 as compared with the similar 2023 period reflect the Company's management of liquidity.
Long-term borrowings averaged $11.4 billion and $11.5 billion in the three-month periods ended September 30, 2024 and June 30, 2024, respectively. In the recent quarter the Company issued $650 million of asset-backed notes secured by equipment finance loans and leases and $400 million of fixed-rate subordinated notes matured. For the nine-month periods ended September 30, 2024 and 2023, long-term borrowings averaged $10.9 billion and $7.1 billion, respectively. The increased usage of borrowing facilities in the 2024 period reflects the Company's strategies to diversify its wholesale funding sources to provide long-term funding stabilization and prepare for proposed regulations enumerating certain long-term debt requirements as described in Part I, Item 1 of M&T's 2023 Annual Report.
Additional information regarding borrowings is provided in notes 5 and 12 of Notes to Financial Statements.
Net interest margin
Taxable-equivalent net interest income can be impacted by changes in the composition of the Company's earning assets and interest-bearing liabilities, as discussed herein, as well as changes in interest rates and spreads. Net interest spread, or the difference between the yield on earning assets and the rate paid on interest-bearing liabilities, was 2.60% in the recent quarter, up 4 basis points from 2.56% in the second quarter of 2024. The increase in the net interest spread from the second quarter of 2024 reflected stable yields on average earning assets and a decrease in the cost of interest-bearing liabilities. The yield on earning assets during the third quarter of 2024 was 5.82%, unchanged from the second quarter of 2024. The yield on investment securities increased 9 basis points reflecting purchases of investment securities in the recent quarter with a higher yield than maturing securities. That increase was offset by a decline in the yield on interest-bearing deposits at the FRB of New York. The yield on loans was unchanged from 2024's second quarter. The rate paid on interest-bearing liabilities was 3.22%, down 4 basis points from the second quarter of 2024 reflecting reduced funding from short-term borrowings and brokered time deposits. For the first nine months of 2024, the net interest spread was 2.55%, down from 3.02% in the corresponding year-earlier period.
- 54 -

Higher rates paid on interest-bearing deposits and borrowings that outpaced higher yields earned on investment securities, loans and other earning assets, largely contributed to that decline in net interest spread.
Net interest-free funds consist largely of noninterest-bearing demand deposits and shareholders’ equity, partially offset by bank owned life insurance and non-earning assets, including goodwill and core deposit and other intangible assets. Net interest-free funds averaged $60.6 billion in the third quarter of 2024, down from $61.5 billion in the second quarter of 2024. Net interest-free funds averaged $61.2 billion and $68.8 billion in the first nine months of 2024 and 2023, respectively. Noninterest-bearing deposits averaged $46.2 billion in the third quarter of 2024, compared with $47.7 billion in the second quarter of 2024, and $47.5 billion in the first nine months of 2024 as compared with $57.3 billion in the first nine months of 2023. The declines in average noninterest-bearing deposits in the respective comparative periods reflect customer use of off-balance sheet investment products and a shift in deposits to interest-bearing accounts in an environment of elevated interest rates. The contribution of net interest-free funds to net interest margin was 1.02% in the third quarter of 2024, compared with 1.03% in the second quarter of 2024. In the first nine months of 2024 and 2023, the contribution of net interest-free funds to net interest margin was 1.03% and .89%, respectively. The increased contribution of net interest-free funds to net interest margin in the first nine months of 2024 as compared with the first nine months of 2023 reflects higher rates paid on interest-bearing liabilities used to value net interest-free funds.
Reflecting the changes to the net interest spread and the contribution of net interest-free funds as described herein, the Company’s net interest margin was 3.62% in the third quarter of 2024, compared with 3.59% in the second quarter of 2024. During the first nine months of 2024 and 2023, the net interest margin was 3.58% and 3.91%, respectively. That 33 basis-point narrowing of the net interest margin reflects an increase in the rates paid on the Company's sources of funding which has outpaced the rise in yields on earning assets. Future changes in market interest rates or spreads, as well as changes in the composition of the Company’s portfolios of earning assets and interest-bearing liabilities that result in changes to spreads, could impact the Company’s net interest income and net interest margin.
Management assesses the potential impact of future changes in interest rates and spreads by projecting net interest income under several interest rate scenarios. In managing interest rate risk, the Company has utilized interest rate swap agreements to modify the repricing characteristics of certain portions of its earning assets and interest-bearing liabilities. Under the terms of those interest rate swap agreements, the Company generally received payments based on the outstanding notional amount at fixed rates and made payments at variable rates. Periodic settlement amounts arising from these agreements are reflected in either the yields on earning assets or the rates paid on interest-bearing liabilities. The Company enters into forward-starting interest rate swap agreements predominantly to hedge interest rate exposures expected in future periods. The following table summarizes information about interest rate swap agreements entered into for interest rate risk management purposes at September 30, 2024 and December 31, 2023.

Provision for Credit Losses
A provision for credit losses is recorded to adjust the level of the allowance to reflect expected credit losses that are based on economic forecasts as of each reporting date. A provision for credit losses of $120 million was recorded in the third quarter of 2024, compared with $150 million in the second quarter of 2024. The lower provision for credit losses in the recent quarter as compared with the second quarter of 2024 reflects a decline in commercial and industrial and commercial real estate criticized loans, partially offset by growth in commercial and industrial and consumer loan portfolios. For the nine months ended September 30, 2024 and 2023, the Company recorded a provision for credit losses of $470 million and $420 million, respectively. The higher provision for credit losses in the first nine months of 2024 as compared with the similar 2023 period reflects declines in commercial real estate values, including office properties, and higher interest rates contributing to a deterioration in the performance of loans to certain commercial borrowers, including nonautomotive dealers and health services facilities, as well as growth in certain sectors of M&T's commercial and industrial and consumer loan portfolios.

(a) Predominantly government-guaranteed residential real estate loans.
The $98 million decline in nonaccrual loans from June 30, 2024 to September 30, 2024 reflects lower commercial real estate nonaccrual loans of $122 million. As compared with December 31, 2023, the $240 million decline in nonaccrual loans at September 30, 2024 reflects a $379 million reduction in commercial real estate nonaccrual loans, partially offset by a $140 million increase in commercial and industrial nonaccrual loans. At September 30, 2024, approximately 57% of nonaccrual commercial and industrial and commercial real estate loans were considered current with respect to their payment status.
Government-guaranteed loans designated as accruing loans past due 90 days or more included one-to-four family residential mortgage loans serviced by the Company that were repurchased to reduce associated servicing costs, including a requirement to advance principal and interest payments that had not been received from individual mortgagors. Despite the loans being purchased by the Company, the insurance or guarantee by the applicable government-related entity remains in force. The outstanding principal balances of the repurchased loans included in the amounts noted herein that are guaranteed by government-related entities totaled $204 million at September 30, 2024, $170 million at June 30, 2024, $228 million at December 31, 2023 and $202 million at September 30, 2023. Accruing loans past due 90 days or more not guaranteed by government-related entities were loans considered to be with creditworthy borrowers that were in the process of collection or renewal.
Approximately 72% of loans 30 to 89 days past due were less than 60 days delinquent at September 30, 2024, compared with 74% at June 30, 2024 and 73% at December 31, 2023. Additional information about past due and nonaccrual loans at September 30, 2024 and December 31, 2023 is included in note 4 of Notes to Financial Statements.
During the normal course of business, the Company modifies loans to maximize recovery efforts. The modifications that the Company grants are typically comprised of maturity extensions, payment deferrals and interest rate reductions but may also include other modification types. The Company may offer such modified terms to borrowers experiencing financial difficulty. Such modified loans may be considered nonaccrual if the Company does not expect to collect the contractual cash flows owed under the loan agreement. Information about modifications of loans to borrowers experiencing financial difficulty is included in note 4 of Notes to Financial Statements.

The Company utilizes a loan grading system to differentiate risk amongst its commercial and industrial loans and commercial real estate loans. Loans with a lower expectation of default are assigned one of ten possible “pass” loan grades while specific loans determined to have an elevated level of credit risk are designated as “criticized.” A criticized loan may be designated as “nonaccrual” if the Company no longer expects to collect all amounts according to the contractual terms of the loan agreement or the loan is delinquent 90 days or more.
Line of business personnel in different geographic locations with support from and review by the Company’s credit risk personnel review and reassign loan grades based on their detailed knowledge of individual borrowers and their judgment of the impact on such borrowers resulting from changing conditions in their respective regions. The Company’s policy is that, at least annually, updated financial information is obtained from commercial borrowers associated with pass grade loans and additional analysis performed. On a quarterly basis, the Company’s centralized credit risk department personnel review criticized commercial and industrial loans and commercial real estate loans greater than $5 million to determine the appropriateness of the assigned loan grade, including whether the loan should be reported as accruing or nonaccruing. For criticized nonaccrual loans, additional meetings are held with loan officers and their managers, workout specialists and senior management to discuss each of the relationships. In analyzing criticized loans, borrower-specific information is reviewed, including operating results, future cash flows, recent developments and the borrower’s outlook, and other pertinent data. The timing and extent of potential losses, considering collateral valuation and other factors, and the Company’s potential courses of action are contemplated.
Targeted loan reviews have periodically been performed over segments of loan portfolios that are experiencing heightened credit risk due to current or anticipated economic conditions. The intention of such reviews is to identify trends across such portfolios and inform portfolio risk limits and loss mitigation strategies. In 2023 and 2024, the Company completed targeted loan reviews covering the majority of its investor-owned commercial real estate portfolio, inclusive of construction loans, with a focus on criticized loans and loans with maturities in the next twelve months. The primary source of repayment of these loans is typically tenant lease payments to the investor/borrower. Elevated vacancies and higher interest rates have contributed to lower current and anticipated future debt service coverage ratios, which have and may continue to influence the ability of borrowers to make existing loan payments. Lower debt service coverage ratios and reduced commercial real estate values also impact the ability of borrowers, in particular those borrowers with loans secured by office properties, to refinance their obligations at loan maturity. Despite these challenges, the ability of borrowers to service loans secured by certain investor-owned real estate, including health services, retail and multifamily properties has modestly improved in recent quarters. Criticized investor-owned commercial real estate loans totaled $6.7 billion or 23% of such loans at September 30, 2024, improved from $7.6 billion or 26% at June 30, 2024 and $8.8 billion or 27% of such loans at December 31, 2023. Investor-owned commercial real estate loans comprised 62%, 63% and 70% of total criticized loans at September 30, 2024, June 30, 2024 and December 31, 2023, respectively. The weighted-average LTV ratio for investor-owned commercial real estate loans was approximately 56% at each of September 30, 2024, June 30, 2024 and December 31, 2023. Criticized loans secured by investor-owned commercial real estate had a weighted-average LTV ratio of approximately 63%, 62% and 61% at September 30, 2024, June 30, 2024 and December 31, 2023, respectively.
The Company monitors its concentration of commercial real estate lending as a percentage of its Tier 1 capital plus its allowable allowance for credit losses, consistent with a metric utilized to differentiate such concentrations amongst regulated financial institutions. This metric, as prescribed in supervisory guidance, excludes loans secured by commercial real estate considered to be owner-occupied, but includes certain other loans, such as loans to real estate investment trusts, that are classified as commercial and industrial loans. The Company's commercial real estate loan concentration approximated 148% of Tier 1 capital plus its allowable allowance for credit losses at September 30, 2024, compared with 151% at June 30, 2024 and 183% at December 31, 2023. The Company has intentionally reduced its relative concentration of investor-owned commercial real estate loans throughout 2023 and the first nine months of 2024.

Total criticized commercial and industrial loans and commercial real estate loans were $10.9 billion, $12.1 billion and $12.6 billion at September 30, 2024, June 30, 2024 and December 31, 2023, respectively. Criticized loans represented 12.2% of total commercial and industrial and commercial real estate loans at September 30, 2024, compared with 13.5% at June 30, 2024 and 14.0% at December 31, 2023. At each of September 30, 2024 and June 30, 2024, permanent finance commercial real estate loans comprised 43% of total criticized loans, compared with 49% at December 31, 2023. Commercial and industrial loans represented 38%, 37% and 30% of total criticized loans at September 30, 2024, June 30, 2024 and December 31, 2023, respectively. At September 30, 2024, construction loans represented 19% of total criticized loans, compared with 20% at June 30, 2024 and 21% at December 31, 2023. Loans to nonautomotive finance dealers and loans to borrowers secured by owner-occupied health services properties predominantly contributed to the $424 million increase in commercial and industrial criticized loans from December 31, 2023 to September 30, 2024. The $2.1 billion decline in criticized commercial real estate loans from December 31, 2023 to September 30, 2024 was largely driven by lower criticized construction loans and loans secured by health services, retail and multifamily properties, partially offset by a rise in criticized loans secured by office properties.
The Company’s loss identification and estimation techniques with respect to loans secured by residential real estate make reference to loan performance and house price data in specific areas of the country where collateral securing the Company’s residential real estate loans is located. For residential real estate-related loans, including home equity loans and lines of credit, the excess of the loan balance over the net realizable value of the property collateralizing the loan is charged-off when the loan becomes 150 days delinquent. That charge-off is based on recent indications of value from external parties that are generally obtained shortly after a loan becomes nonaccrual. Loans to consumers that file for bankruptcy are generally charged-off to estimated net collateral value shortly after the Company is notified of such filings. Limited documentation first lien mortgage loans represent loans secured by residential real estate that at origination typically included some form of limited borrower documentation requirements as compared with more traditional loans. The Company no longer originates limited documentation loans. With respect to junior lien loans, to the extent known by the Company, if a related senior lien loan would be on nonaccrual status because of payment delinquency, even if such senior lien loan was not owned by the Company, the junior lien loan or line that is owned by the Company is placed on nonaccrual status. In monitoring the credit quality of its home equity portfolio for purposes of determining the allowance for credit losses, the Company reviews delinquency and nonaccrual information and considers recent charge-off experience. When evaluating individual home equity loans and lines of credit for charge-off and for purposes of determining the allowance for credit losses, the Company considers the required repayment of any first lien positions related to collateral property. Information about the location of loans secured by residential real estate is presented in the following table.

Factors that influence the Company’s credit loss experience include overall economic conditions affecting businesses and consumers, generally, but also residential and commercial real estate valuations, in particular, given the size of the Company’s real estate loan portfolios. Commercial real estate valuations can be highly subjective, as they are based upon many assumptions. Such valuations can be significantly affected over relatively short periods of time by changes in business climate, economic conditions, interest rates and, in many cases, the results of operations of businesses and other occupants of the real property. Similarly, residential real estate valuations can be impacted by housing trends, the availability of financing at reasonable interest rates and general economic conditions affecting consumers.

Allowance for credit losses
Management determines the allowance for credit losses under accounting guidance that requires estimating the amount of current expected credit losses over the remaining contractual term of the loan and lease portfolio. A description of the methodologies used by the Company to estimate its allowance for credit losses can be found in note 4 of Notes to Financial Statements.
In establishing the allowance for credit losses, the Company estimates losses attributable to specific troubled credits identified through both normal and targeted credit review processes and also estimates losses for other loans and leases with similar risk characteristics on a collective basis. For purposes of determining the level of the allowance for credit losses, the Company evaluates its loan and lease portfolio by type. At the time of the Company’s analysis regarding the determination of the allowance for credit losses as of September 30, 2024 concerns existed about the impact of elevated levels of inflation and potential increases in unemployment on the discretionary income and purchasing power of consumer borrowers; slower economic growth in future quarters; the volatile nature of global markets and international economic conditions that could impact the U.S. economy; Federal Reserve positioning of monetary policy, including the effects of liquidity in financial markets; downward pressures on commercial real estate values, especially in the office sector; elevated interest rates and wage pressures impacting commercial borrowers, including nonautomotive finance dealers; and the extent to which borrowers may be negatively affected by general economic conditions.
The Company generally estimates current expected credit losses on loans with similar risk characteristics on a collective basis. To estimate expected losses, the Company utilizes statistically developed models to project principal balances over the remaining contractual lives of the loan portfolios and determine estimated credit losses through a reasonable and supportable forecast period. The Company’s approach for estimating current expected credit losses for loans and leases at each period end reporting date included utilizing macroeconomic assumptions to project losses over a two-year reasonable and supportable forecast period. Subsequent to the forecast period, the Company reverted to longer-term historical loss experience, over a period of one year, to estimate expected credit losses over the remaining contractual life. Forward-looking estimates of certain macroeconomic variables are determined by the M&T Scenario Review Committee, which is comprised of senior management business leaders and economists. The assumptions utilized as of September 30, 2024, June 30, 2024 and December 31, 2023 are presented in the following table and were based on information available at or near the time the Company was preparing its estimate of expected credit losses as of those dates.

Year 1 Year 2 Cumulative Year 1 Year 2 Cumulative Year 1 Year 2 Cumulative

Home price index growth/
decline rate 		-.4 2.4 2.0 -.1 2.1 2.0 -3.2 -.1 -3.3
In establishing the allowance for credit losses, the Company also considers the impact of portfolio concentrations, imprecision in economic forecasts, geopolitical conditions and other risk factors that influence the loss estimation process. With respect to economic forecasts, the Company assessed the likelihood of alternative economic scenarios during the two-year reasonable and supportable forecast period. Generally, an increase in unemployment rate or a decrease in any of the rate of change in GDP, commercial real estate prices or home prices could have an adverse impact on expected credit losses and may result in an increase to the allowance for credit losses. Forward-looking economic forecasts are subject to inherent imprecision and future events may differ materially from forecasted events. In consideration of such uncertainty, the following alternative economic scenarios were considered to estimate the possible impact on modeled credit losses.

These examples are only a few of the numerous possible economic scenarios that could be utilized in assessing the sensitivity of expected credit losses. The estimated impacts on credit losses in such scenarios pertain only to modeled credit losses and do not include consideration of other factors the Company may evaluate when determining its allowance for credit losses. As a result, it is possible that the Company may, at another point in time, reach different conclusions regarding credit loss estimates. The Company’s process for determining the allowance for credit losses undergoes quarterly and periodic evaluations by independent risk management personnel, which among many other considerations, evaluate the reasonableness of management’s methodology and significant assumptions. Further information about the Company’s methodology to estimate expected credit losses is included in note 4 of Notes to Financial Statements.
Management has assessed that the allowance for credit losses at September 30, 2024 appropriately reflected expected credit losses inherent in the portfolio as of that date. The allowance for credit losses totaled $2.2 billion at each of September 30, 2024 and June 30, 2024, compared with $2.1 billion at December 31, 2023. As a percentage of loans and leases outstanding, the allowance was 1.62% at September 30, 2024, 1.63% at June 30, 2024 and 1.59% at December 31, 2023. The increase in the allowance for credit losses as a percentage of loans and leases outstanding since December 31, 2023 reflects a higher level of credit losses expected on certain commercial borrowers and growth in consumer recreational finance loans. Included in the allocation of the allowance for credit losses were reserves for loans secured by office properties of 4.70% at September 30, 2024, 4.33% at June 30, 2024 and 4.37% at December 31, 2023. The level of the allowance reflects management’s evaluation of the loan and lease portfolio using the methodology and considering the factors as described herein. Should the various economic forecasts and credit factors considered by management in establishing the allowance for credit losses change and should management’s assessment of losses in the loan portfolio also change, the level of the allowance as a percentage of loans could increase or decrease in future periods. The reported level of the allowance reflects management’s evaluation of the loan and lease portfolio as of each respective date. Furthermore, the Company's allowance is general in nature and is available to absorb losses from any loan or lease category.
The ratio of the allowance for credit losses to total nonaccrual loans at September 30, 2024, June 30, 2024 and December 31, 2023 was 114%, 109% and 98%, respectively. Given the Company’s general position as a secured lender and its practice of charging off loan balances when collection is deemed doubtful, that ratio and changes in the ratio are generally not an indicative measure of the adequacy of the Company’s allowance for credit losses, nor does management rely upon that ratio in assessing the adequacy of the Company’s allowance for credit losses.

Trust income was $170 million in the recent quarter, unchanged from the second quarter of 2024. The modest decrease in Wealth Management revenues reflected seasonal tax service fees earned in the second quarter of 2024, partially offset by higher fees resulting from improved market performance of assets under management.
For the nine months ended September 30, 2024, trust income totaled $500 million, compared with $521 million in the similar 2023 period.
• In April 2023, M&T completed the divestiture of its CIT business to a private equity firm. Revenues associated with that business and included in Institutional Services trust income totaled $60 million in the first nine months of 2023. After considering expenses, the results of operations of that business were not material to M&T's net income in 2023's initial nine months.
• Institutional Services trust income not related to the CIT business increased $29 million for the first nine months of 2024 as compared with the similar 2023 period reflecting higher sales and fund management fees from its global capital markets business.
• The higher level of trust income in the first nine months of 2024 from the Wealth Management business reflected the impact of higher assets under management and improved market performance associated with those managed assets.
Brokerage services income
Brokerage services income, which includes revenues from the sale of mutual funds and annuities, securities brokerage fees and select investment products of LPL Financial, an independent financial services broker, increased $15 million for the nine months ended September 30, 2024 as compared with the first nine months of 2023 reflecting higher annuities sales.

(a) Tax-exempt income earned from bank owned life insurance includes increases in the cash surrender value of life insurance policies and benefits received. The Company owns both general account and separate account life insurance policies. To the extent market conditions change such that the market value of assets in a separate account bank owned life insurance policy becomes less than the previously recorded cash surrender value, an adjustment is recorded as a reduction to other revenues from operations.
(b) During 2017, the operating losses of BLG resulted in M&T reducing the carrying value of its investment in BLG to zero. Subsequently, M&T has received cash distributions when declared by BLG that result in the recognition of income by M&T. M&T expects cash distributions from BLG in the future, but the timing and amount of those distributions are not within M&T's control. BLG is entitled to receive distributions from its affiliates that provide asset management and other services that are available for distribution to BLG’s owners, including M&T. Information about the Company’s relationship with BLG and its affiliates is included in note 16 of Notes to Financial Statements.
Other revenues from operations were unchanged in the third quarter of 2024 as compared with 2024's second quarter. Other revenues from operations in the first nine months of 2024 declined $208 million from the first nine months of 2023 reflecting a $225 million gain on the sale of the CIT business in April 2023 and an $11 million decline in operating lease income reflecting higher gains on sales of leased equipment recognized in the 2023 period. Those unfavorable factors were partially offset by a $10 million increase in letter of credit and other credit-related fees, reflecting higher lines of credit and line usage fees, partially offset by lower loan syndication fees, and a $5 million increase in distributions received from M&T's investment in BLG.

Salaries and employee benefits
• The number of full time equivalent employees was 21,986 at September 30, 2024, 22,110 at June 30, 2024, 21,980 at December 31, 2023 and 22,424 at September 30, 2023.
• Salaries and employee benefits expense increased $11 million in the third quarter as compared with the second quarter of 2024 reflecting one additional working day in the recent quarter.
• Salaries and employee benefits expense increased $99 million in the nine months ended September 30, 2024 as compared with the year-earlier period r eflecting higher salaries expense from annual merit and other increases and a rise in incentive compensation, partially offset by lower average employee staffing levels.
Nonpersonnel expenses
• FDIC assessments in the first nine months of 2024 reflect estimated special assessment expense of $5 million and $29 million in the second and first quarter of 2024, respectively, related to the FDIC's updated loss estimates associated with certain failed banks. No FDIC special assessment expense was recognized in the comparable 2023 periods.
• Nonpersonnel expenses aggregated $528 million in the recent quarter, down from $533 million in the second quarter of 2024. A decline in FDIC assessments expense was largely offset by an increase in other costs of operations predominantly due to the Company's obligation under various agreements to share in losses stemming from certain litigation of Visa, Inc.
• Nonpersonnel expenses decreased $33 million to $1.62 billion in the nine months ended September 30, 2024 as compared with $1.66 billion in the first nine months of 2023, reflecting a decline in professional and other services expense of $50 million, predominantly from lower sub-advisory fees following the sale of the CIT business in April 2023, and a decrease in losses associated with certain retail banking activities. Those favorable factors were partially offset by a rise in outside data processing and software costs of $44 million and higher FDIC assessments expense as previously described.
Income Taxes
Income tax expense was $188 million in the third quarter of 2024, compared with $200 million in the second quarter of 2024. For the nine-month periods ended September 30, 2024 and 2023, the provision for income taxes was $521 million and $734 million, respectively. The Company's effective tax rates were 20.7% and 23.4% for the quarters ended September 30, 2024 and June 30, 2024, respectively, and 21.5% and 24.5% for the nine-month periods ended September 30, 2024 and 2023, respectively. The income tax expense in the recent quarter reflects a $14 million discrete tax benefit related to certain tax credits claimed on a prior year return. The income tax expense in the first nine months of 2024 reflects that discrete tax benefit and, in the first quarter of 2024, a $17 million net discrete tax benefit related to the resolution of an income tax matter inherited from the acquisition of People's United. The effective tax rate is affected by the level of income earned that is exempt from tax relative to the overall level of pre-tax income, the amount of income allocated to the various state and local jurisdictions where the Company operates, because tax rates differ among such jurisdictions, and the impact of any large discrete or infrequently occurring items. The Company’s effective tax rate in future periods may also be affected by any change in income tax laws or regulations and interpretations of income tax regulations that differ from the Company’s interpretations by any of the various tax authorities that may examine tax returns filed by M&T or any of its subsidiaries.

Liquidity Risk
As a financial intermediary, the Company is exposed to various risks, including liquidity and market risk. Liquidity refers to the Company’s ability to ensure that sufficient cash flow and liquid assets are available to satisfy current and future obligations, including demands for loans and deposit withdrawals, funding operating costs and other corporate purposes. Liquidity risk arises whenever cash flows associated with financial instruments included in assets and liabilities differ.
The most significant source of funding for the Company is core deposits, which are generated from a large base of consumer, corporate and institutional customers. That customer base has, over the past several years, become more geographically diverse as a result of expansion of the Company’s businesses. Nevertheless, the Company faces competition in offering products and services from a large array of financial market participants, including banks, thrifts, mutual funds, securities dealers and others. Core deposits totaled $150.2 billion at September 30, 2024 and $146.5 billion at December 31, 2023. The increase in core deposits since December 31, 2023 reflects higher savings and interest-checking deposits, including higher transitory commercial and institutional services deposits near the end of the recent quarter, partially offset by lower noninterest-bearing deposits as customers shifted funds to interest-bearing accounts in an elevated interest rate environment.
The Company supplements funding provided through deposits with various short-term and long-term wholesale borrowings, including overnight federal funds purchased, repurchase agreements, advances from FHLBs, brokered deposits and longer-term borrowings. M&T Bank has access to additional funding sources through secured borrowings from the FHLB of New York and the FRB of New York. M&T Bank is also a counterparty to the FRB of New York standing repurchase agreement facility, which allows it to enter into overnight repurchase transactions using eligible investment securities. The Company has, in the past, issued subordinated capital notes and junior subordinated debentures associated with trust preferred securities to provide liquidity and enhance regulatory capital ratios. At September 30, 2024 and December 31, 2023, long-term borrowings aggregated $11.6 billion and $8.2 billion, respectively, and short-term borrowings aggregated $2.6 billion and $5.3 billion, respectively. Information about the Company's borrowings is presented in note 5 of Notes to Financial Statements.
The Company's wholesale funding sources include the placement of brokered deposits. The Company had brokered savings and interest-checking deposit accounts which aggregated $9.3 billion at September 30, 2024 and $7.8 billion at December 31, 2023. Reflecting a mix shift in the Company's wholesale funding strategy, brokered time deposits totaled $2.0 billion at September 30, 2024, down $4.1 billion from $6.1 billion at December 31, 2023, as brokered time deposits matured. Approximately 76% of brokered time deposits at September 30, 2024 have a contractual maturity date in the next 12 months.
Total uninsured deposits were estimated to be $74.8 billion at September 30, 2024 and $67.0 billion at December 31, 2023. Approximately $11.2 billion and $10.7 billion of those uninsured deposits were collateralized by the Company at September 30, 2024 and December 31, 2023, respectively. The Company maintains available liquidity sources which represent approximately 134% of uninsured deposits that are not collateralized by the Company at September 30, 2024.
The Company’s ability to obtain funding from these sources could be negatively impacted should the Company experience a substantial deterioration in its financial condition or its debt ratings or should the availability of funding become restricted due to a disruption in the financial markets. The Company attempts to quantify such risks by conducting scenario analyses that estimate the liquidity impact resulting from a debt ratings downgrade and other market events. Such impact is estimated by attempting to measure the effect on available unsecured lines of credit, available capacity from secured borrowing sources and securitizable assets.
M&T’s primary source of funds to pay for operating expenses, shareholder dividends and treasury stock repurchases has historically been the receipt of dividends from its bank subsidiaries, which are subject to various regulatory limitations. Dividends from any bank subsidiary to M&T are limited by the amount of earnings of the subsidiary in the current year and the two preceding years. For purposes of that test, at September 30, 2024 approximately $2.6 billion was available for payment of dividends to M&T from bank subsidiaries. M&T may also obtain funding through long-term borrowings. Further information about the long-term outstanding borrowings of M&T is provided in note 5 of Notes to Financial Statements. As a bank holding company, M&T is obligated to serve as a managerial
- 71 -

and financial source of strength to its bank subsidiaries as described in Part I, Item 1, "Business" in M&T's 2023 Annual Report. As its ability to access the capital markets may be affected by market disruptions, M&T maintains sufficient cash resources at its parent company to satisfy projected cash outflows for an extended period without reliance on dividends from subsidiaries or external financing. As of September 30, 2024, M&T's parent company liquidity covered projected cash outflows for 35 months, including dividends on common and preferred stock, debt service and scheduled debt maturities.
In addition to deposits and borrowings, other sources of liquidity include maturities and repayments of investment securities, loans and other earning assets, as well as cash generated from operations, such as fees collected for services. The Company also has the ability to securitize or sell certain financial assets, including various loan types, to provide other liquidity alternatives. U.S. Treasury and federal agency securities and government issued or guaranteed mortgage-backed securities comprised 92% of the Company's debt securities portfolio at September 30, 2024. The weighted-average durations of debt investment securities available for sale and held to maturity at September 30, 2024 were 2.3 years and 5.2 years, respectively.
The Company enters into contractual obligations in the normal course of business that require future cash payments. Such obligations include, among others, payments related to deposits, borrowings, leases and other contractual commitments. Off-balance sheet commitments to customers may impact liquidity, including commitments to extend credit, standby letters of credit, commercial letters of credit, financial guarantees and indemnification contracts, and commitments to sell real estate loans. Because many of these commitments or contracts expire without being funded in whole or in part, the contract amounts are not necessarily indicative of future cash flows. Further discussion of these commitments is provided in note 14 of Notes to Financial Statements.
The Company's Executive ALCO Committee closely monitors the Company’s liquidity position on an ongoing basis for compliance with internal policies and regulatory expectations. As a Category IV institution, the Company adheres to enhanced liquidity standards which require the performance of internal liquidity stress testing. The stress testing is designed to ensure the Company has sufficient liquidity to withstand both institution-specific and market-wide stress scenarios. For each scenario, the Company applies liquidity stress which may include deposit run-off, increased draws on unfunded loan commitments, increased collateral need for margin calls, increased haircuts on investment security-based funding and reductions in unsecured and secured borrowing capacity. Stress scenarios are measured over various time frames ranging from overnight to twelve months. As required by regulation, the Company maintains a liquidity buffer comprised of cash and highly liquid unencumbered securities to cover a 30-day stress horizon. Liquidity stress events occurring over longer time horizons can be mitigated by the availability of secured funding sources at the FHLB of New York and FRB of New York. The following table is a summary of the Company's available sources of liquidity at September 30, 2024 and December 31, 2023.
AVAILABLE LIQUIDITY SOURCES
(Dollars in millions) September 30, 2024 December 31, 2023
Deposits at the FRB of New York $ 24,288 $ 27,957
Unused secured borrowing facilities:
FRB of New York 23,814 17,106
FHLB of New York 15,757 16,765
Unencumbered investment securities (after estimated haircuts) 21,603 16,480
Total $ 85,462 $ 78,308
Management continuously evaluates the use and mix of its various available funding alternatives, including short-term borrowings, issuances of long-term debt, the placement of brokered deposits and the securitization of certain loan products. Management does not anticipate engaging in any activities, either currently or in the long term, for which adequate funding would not be available and would therefore result in a significant strain on liquidity at either M&T or its subsidiary banks. In accordance with liquidity regulations, the Company maintains a contingency funding plan to facilitate on-going liquidity management in times of liquidity stress. The plan outlines various funding options available during a liquidity stress event and establishes a clear escalation protocol to be followed within the Company's risk management framework. The plan sets forth funding strategies and procedures that
- 72 -

management can quickly leverage to assist in decision-making and specifies roles and responsibilities for departments impacted by a potential liquidity stress event.
Market Risk and Interest Rate Sensitivity
Market risk is the risk of loss from adverse changes in the market prices and/or interest rates of the Company’s financial instruments. The primary market risk the Company is exposed to is interest rate risk. Interest rate risk arises from the Company’s core banking activities of lending and deposit-taking, because assets and liabilities reprice at different times and by different amounts as interest rates change. As a result, net interest income earned by the Company is subject to the effects of changing interest rates. The Company measures interest rate risk by calculating the variability of net interest income in future periods under various interest rate scenarios using projected balances for earning assets, interest-bearing liabilities and derivatives used to hedge interest rate risk. Management’s philosophy toward interest rate risk management is to limit the variability of net interest income. The balances of financial instruments used in the projections are based on expected growth from forecasted business opportunities, anticipated prepayments of loans and investment securities, and expected maturities of investment securities, loans and deposits. The Company has entered into interest rate swap agreements to help manage exposure to interest rate risk. At September 30, 2024, the aggregate notional amount of interest rate swap agreements entered into for interest rate risk management purposes that were currently in effect was $22.2 billion. In addition, the Company has entered into $8.4 billion of forward-starting interest rate swap agreements designated for hedging purposes. Information about interest rate swap agreements entered into for interest rate risk management purposes is included herein under the heading “Net interest margin” and in note 11 of Notes to Financial Statements.
The Company’s Executive ALCO Committee monitors the sensitivity of the Company’s net interest income to changes in interest rates with the aid of a computer model that forecasts net interest income under different interest rate scenarios. In modeling changing interest rates, the Company considers different yield curve shapes that contemplate both parallel (that is, when interest rates at each point of the yield curve change by the same magnitude) and non-parallel (that is, allowing interest rates at points on the yield curve to change by different amounts) shifts in the yield curve. The Company also contemplates instantaneous and gradual shifts in the yield curve over the scenario time horizon. In utilizing the model, market-implied forward interest rates over the subsequent twelve months are generally used to determine a base interest rate scenario for the net interest income simulation. That calculated base net interest income is then compared with the income calculated under the varying interest rate scenarios. The model considers the impact of ongoing lending and deposit-gathering activities, as well as interrelationships in the magnitude and timing of the repricing of financial instruments, including the effect of changing interest rates on expected prepayments and maturities. Management has taken actions to mitigate exposure to interest rate risk through the use of on- or off-balance sheet financial instruments and intends to do so in the future. Possible actions include, but are not limited to, changes in the pricing of loan and deposit products, modifying the composition of earning assets and interest-bearing liabilities, and adding to, modifying or terminating existing interest rate swap agreements or other financial instruments used for interest rate risk management purposes.
The accompanying table as of September 30, 2024 and December 31, 2023 displays the estimated impact on net interest income in the base scenario described above resulting from changes in market interest rates. The scenarios presented in the table below assume a gradual and parallel change in interest rates across repricing categories during the first modeling year.

The Company utilized many assumptions to calculate the impact that changes in interest rates may have on net interest income. The more significant of those assumptions included the rate of prepayments of mortgage-related assets, cash flows from derivative and other financial instruments, loan and deposit volumes, mix and pricing, and deposit maturities. Changes in amounts presented since December 31, 2023 reflect changes in portfolio composition (including purchases of investment securities, shifts between noninterest-bearing and interest-bearing deposit products, lower levels of brokered time deposits and short-term borrowings and higher levels of long-term borrowings), the level of market-implied forward interest rates and hedging actions taken by the Company. M&T's cumulative deposit pricing beta, which is the change in deposit pricing in response to a change in market interest rates, approximated 55 percent amidst a rising interest rate environment from the first quarter of 2022 through the second quarter of 2024. Reflecting the first cut of the federal funds target interest rate since March 2020, the FOMC decreased that rate by 50 basis points on September 18, 2024. The assumptions used in interest rate sensitivity modeling are inherently uncertain and, as a result, the Company cannot precisely predict the impact of changes in interest rates on net interest income. Actual results may differ significantly from those presented due to the timing, magnitude and frequency of changes in interest rates and changes in market conditions and interest rate differentials (spreads) between maturity/repricing categories, as well as any actions, such as those previously described, which management may take to counter such changes. Management also uses an “economic value of equity” model to supplement the modeling technique described above and provide a long-term interest rate risk metric. Economic value of equity is a point-in-time analysis of the economic sensitivity of assets, liabilities and off-balance sheet positions that incorporates all cash flows over their estimated remaining lives. Management measures the impact of changes in market values due to interest rates under a number of scenarios, including immediate shifts of the yield curve.
In addition to the effect of interest rates, changes in fair value of the Company’s financial instruments can also result from a lack of trading activity for similar instruments in the financial markets. Information about the fair valuation of financial instruments is presented in note 13 of Notes to Financial Statements.
The Company enters into interest rate and foreign exchange contracts to meet the financial needs of customers that it includes in its consolidated financial statements as other non-hedging derivatives within other assets and other liabilities. Financial instruments utilized for such activities consist predominantly of interest rate swap agreements and forward and futures contracts related to foreign currencies. The Company generally mitigates the foreign currency and interest rate risk associated with customer activities by entering into offsetting positions with third parties that are also included in other assets and other liabilities. The fair values of non-hedging derivative positions associated with interest rate contracts and foreign currency and other option and futures contracts are presented in note 11 of Notes to Financial Statements. As with any non-government guaranteed financial instrument, the Company is exposed to credit risk associated with counterparties to its non-hedging derivative activities. Although the notional amounts of these contracts are not recorded in the Consolidated Balance Sheet, the unsettled fair values of such financial instruments are recorded in the Consolidated Balance Sheet. The fair values of such non-hedging derivative assets and liabilities recognized on the Consolidated Balance Sheet were $232 million and $584 million, respectively, at September 30, 2024 and $256 million and $898 million, respectively, at December 31, 2023. The fair value asset and liability amounts at September 30, 2024 have been reduced by contractual settlements of $496 million and $51 million, respectively, and at December 31, 2023 have been reduced by contractual settlements of $783 million and $32 million, respectively. The amounts associated with the Company's non-hedging derivative activities at September 30, 2024 and December 31, 2023 reflect changes in values associated with interest rate swap agreements entered into with commercial customers that are not subject to periodic variation margin settlement payments.
Trading account assets were $102 million at September 30, 2024 and $106 million at December 31, 2023. Included in trading account assets were assets related to deferred compensation plans of $22 million at each of September 30, 2024 and December 31, 2023. Changes in the fair values of such assets are recorded as trading account and other non-hedging derivative gains in the Consolidated Statement of Income. Included in accrued interest and other liabilities in the Consolidated Balance Sheet were $27 million of liabilities related to deferred compensation plans at each of September 30, 2024 and December 31, 2023. Changes in the balances of such liabilities due to the valuation of allocated investment options to which the liabilities are indexed are recognized in other costs of operations in the Consolidated Statement of Income. Also included in trading account assets were investments in mutual funds and
- 74 -

other assets that the Company was required to hold under terms of certain non-qualified supplemental retirement and other benefit plans that were assumed by the Company in various acquisitions. Those assets totaled $80 million at each of September 30, 2024 and December 31, 2023.
Given the Company’s policies and positions, management believes that the potential loss exposure to the Company resulting from market risk associated with trading account and other non-hedging derivative activities was not material at September 30, 2024, however, as previously noted, the Company is exposed to credit risk associated with counterparties to transactions related to the Company’s actions to mitigate foreign currency and interest rate risk associated with customer activities. Information about the Company’s use of derivative financial instruments is included in note 11 of Notes to Financial Statements.

Reflected in the carrying amount of available-for-sale investment securities at September 30, 2024 were pre-tax effect unrealized gains of $177 million on securities with an amortized cost of $10.8 billion and pre-tax effect unrealized losses of $108 million on securities with an amortized cost of $5.9 billion. Information concerning the Company’s fair valuations of investment securities is provided in notes 3 and 13 of Notes to Financial Statements. As also described in note 3 of Notes to Financial Statements, the Company does not expect any material credit-related losses with respect to its investment securities portfolio at September 30, 2024.
Pursuant to previously approved capital plans and authorizations approved by M&T's Board of Directors, M&T repurchased 1,190,054 shares of its common stock during the recent quarter at an average cost per share of $166.40 resulting in a total cost, including the share repurchase excise tax, of $200 million. No share repurchases occurred in the first or second quarter of 2024. During the first nine months of 2023, M&T repurchased 3,838,157 shares of its common stock at an average cost per share of $154.76 resulting in a total cost, including the share repurchase excise tax, of $600 million. Discretion as to the amount and timing of authorized share repurchases in a given period has been delegated, through the authorization of the Board of Directors, to management and can be influenced by capital and liquidity requirements, including funding of future loan growth and other balance sheet management activities, as well as market and economic conditions.
M&T and its subsidiary banks are required to comply with applicable Capital Rules. Pursuant to those regulations, the minimum capital ratios are as follows:
• 4.5% CET1 to RWA (each as defined in the Capital Rules);
• 6.0% Tier 1 capital (that is, CET1 plus additional Tier 1 capital) to RWA (each as defined in the Capital Rules);
• 8.0% Total capital (that is, Tier 1 capital plus Tier 2 capital) to RWA (each as defined in the Capital Rules); and
• 4.0% Tier 1 capital to average consolidated assets as reported on consolidated financial statements (known as the “leverage ratio”), as defined in the Capital Rules.
Capital Rules require buffers in addition to the minimum risk-based capital ratios noted above. M&T is subject to a SCB requirement that is determined through the Federal Reserve’s supervisory stress tests and M&T’s bank subsidiaries are subject to a 2.5% capital conservation buffer requirement. The buffer requirement must be composed entirely of CET1. M&T's SCB at September 30, 2024 was 4.0%. In June 2024, the Federal Reserve released the results of its most recent supervisory stress tests. Based on those results, on October 1, 2024, M&T's SCB of 3.8% became effective.

Capital Rules generally require the deduction of goodwill and core deposit and other intangible assets, net of applicable deferred taxes, from the calculation of capital in the determination of the minimum capital ratios. As a result of previous business acquisitions, the Company recorded goodwill of $8.5 billion and core deposit and other intangible assets of $107 million at September 30, 2024. Goodwill, as required by GAAP, is not amortized, but rather is tested for impairment at least annually at the business reporting unit level. The Company completed its annual goodwill impairment test in the fourth quarter of 2023 and concluded the amount of goodwill was not impaired at the testing date. The Company has not identified events or circumstances that would more likely than not reduce the fair value of a business reporting unit below its carrying amount at September 30, 2024. Should a business reporting unit with assigned goodwill experience declines in revenue, increased credit losses or expenses, or other adverse developments due to economic, regulatory, competition or other factors, that would be material to that reporting unit, an impairment of goodwill could occur in a future period that could be material to the Company's Consolidated Balance Sheet and its Consolidated Statement of Income. Although a goodwill impairment charge would not have a significant impact on the Company's regulatory tangible capital ratios, it would reduce the capacity of its bank subsidiary, M&T Bank, to dividend earnings to M&T. As described herein under the heading "Liquidity Risk", M&T's parent company liquidity at September 30, 2024 covered projected cash outflows for 35 months, including dividends on common and preferred stock, debt service and scheduled debt maturities. Information concerning goodwill and other intangible assets is included in note 8 of Notes to Financial Statements in M&T's 2023 Annual Report.
The Company is subject to the comprehensive regulatory framework applicable to bank and financial holding companies and their subsidiaries, which includes examinations by a number of regulators. Regulation of financial institutions such as M&T and its subsidiaries is intended primarily for the protection of depositors, the Deposit Insurance Fund of the FDIC and the banking and financial system as a whole, and generally is not intended for the protection of shareholders, investors or creditors other than insured depositors. Changes in laws, regulations and regulatory policies applicable to the Company’s operations can increase or decrease the cost of doing business, limit or expand permissible activities or affect the competitive environment in which the Company operates, all of which could have a material effect on the business, financial condition or results of operations of the Company and on M&T’s ability to pay dividends. For additional information concerning this comprehensive regulatory framework, refer to Part I, Item 1 of M&T's 2023 Annual Report.
As described in Part I, Item 1 of M&T's 2023 Annual Report, the federal banking agencies issued a notice of proposed rulemaking on July 27, 2023 to modify the regulatory capital requirements applicable to large banking organizations with total assets exceeding $100 billion, like the Company. Management continues to evaluate the impact of the proposed rules on the regulatory capital requirements of M&T and its subsidiary banks. At September 30, 2024, the inclusion of accumulated other comprehensive income (loss) components related to investment securities available for sale and defined benefit plan liability adjustments would have reduced the Company's CET1 ratio by 4 basis points.

The Retail Bank segment’s net income was $446 million in the third quarter of 2024, compared with $472 million in the second quarter of 2024.
• Net interest income decreased $3 million reflecting a 7 basis-point narrowing of the net interest margin on deposits and a decrease in average outstanding deposit balances of $1.4 billion, partially offset by a 3 basis-point expansion of the net interest margin on loans and higher average loan balances.
• Provision for credit losses increased $14 million reflecting higher net charge-offs.
• Noninterest expense increased $18 million reflecting a rise in equipment and net occupancy costs of $8 million and higher personnel-related costs of $4 million. Also contributing to the higher expense was an increase in centrally-allocated costs associated with data processing, risk management, and other support services provided to the Retail Bank segment of $3 million.
• Average loans increased $668 million reflecting growth in the segment's portfolio of recreational finance loans and automobile loans, partially offset by lower average residential real estate loans.
• Lower average deposits in the recent quarter as compared with the second quarter of 2024 reflect time deposit account maturities in the recent quarter and lower noninterest-bearing deposits.
Net income for the Retail Bank segment decreased $36 million in the first nine months of 2024 from $1.40 billion in the similar 2023 period.
• Net interest income decreased $21 million reflecting a 2 basis-point narrowing of the net interest margin on each of loans and deposits.
• Provision for credit losses increased $85 million reflecting higher net charge-offs of consumer and business banking loans and loan growth, including recreational vehicle loans and automobile loans.
• Noninterest income increased $38 million primarily due to higher residential mortgage loan servicing revenues, reflecting the bulk purchase of residential mortgage loan servicing rights at the end of the first quarter of 2023, and a rise in service charges on deposit accounts.

- 80 -

• Noninterest expense decreased $14 million predominantly due to lower other cost of operations of $39 million, reflecting lower losses on certain retail banking activities, and a decline in personnel-related costs of $14 million reflecting lower staffing levels, partially offset by higher centrally-allocated costs associated with data processing, risk management, and other support services provided to the Retail Bank segment of $40 million.
• Average loans in the first nine months of 2024 grew $933 million from the similar 2023 period, reflecting higher average consumer loans resulting from an increase in average recreational finance and automobile loans, partially offset by lower average balances of residential real estate loans.

The Institutional Services and Wealth Management segment’s net income decreased $7 million to $137 million in the third quarter of 2024 from $144 million in the second quarter of 2024.
• Net interest income declined $9 million predominantly due to a 21 basis-point narrowing of the net interest margin on deposits.

- 81 -

Net income for the Institutional Services and Wealth Management segment decreased $106 million for the nine months ended September 30, 2024 from $515 million in the comparable 2023 period.
• Net interest income increased $41 million reflecting a widening of the net interest margin on deposits of 25 basis points.
• Noninterest income decreased $218 million predominantly due to the $225 million gain on sale of the CIT business in the second quarter of 2023 and a decline in trust income of $23 million. The lower trust income reflects lower revenues associated with the CIT business of $60 million following its sale, partially offset by higher non-CIT related revenues of $37 million reflecting improved sales in the segment's global capital markets business and a rise in fee income from the wealth management business reflecting higher assets under management and favorable market performance. Those unfavorable factors were partially offset by higher brokerage services income of $14 million, reflecting increased annuities sales.
• Noninterest expense decreased $38 million reflecting a $53 million decline in professional and other services expense due, in part, to lower sub-advisory fees as a result of the sale of the CIT business, partially offset by an increase in personnel-related costs of $8 million.
All Other
The “All Other” category reflects other activities of the Company that are not directly attributable to the reported segments. Reflected in this category are the difference between the provision for credit losses and the calculated provision allocated to the reportable segments; goodwill and core deposit and other intangible assets resulting from the acquisitions of financial institutions; merger-related gains and expenses related to acquisitions; the net impact of the Company’s internal funds transfer pricing methodology; eliminations of transactions between reportable segments; certain non-recurring transactions; and the residual effects of unallocated support systems and general and administrative expenses. The Company’s investment securities portfolio, brokered deposits and short-term and long-term borrowings are generally included in the “All Other” category. In its management of interest rate risk, the Company utilizes interest rate swap agreements to modify the repricing characteristics of certain portfolios of earning assets and interest-bearing liabilities. The results of such activities are captured in the "All Other" category.

The “All Other” category recorded a net loss in the third quarter of 2024 of $101 million, compared with a net loss of $166 million in the second quarter of 2024.

- 82 -

• Provision for credit losses decreased $6 million reflecting the net impact of the allocation of provision for credit losses to reportable segments.

The net loss recorded for the “All Other” category was $511 million for the first nine months of 2024, compared with a net loss of $475 million in the similar 2023 period.
• Net interest expense increased $115 million reflecting the impact of interest rate swap agreements entered into for interest rate risk management purposes and the unfavorable impact from the Company’s allocation methodologies for internal transfers related to funding charges and credits associated with earning assets and interest-bearing liabilities of the Company’s reportable segments.
• Noninterest income decreased $5 million reflecting realized losses on sales of certain non-agency investment securities in the 2024 period, partially offset by an increase in BLG distributions of $5 million.
• Provision for credit losses decreased $50 million reflecting the net impact of the allocation of the provision for credit losses to reportable segments.

Other Matters
On March 6, 2024, the SEC adopted a final rule to enhance and standardize climate-related disclosures by public companies. The final rule requires registrants, including the Company, to disclose their risk management processes for material climate-related risks, governance and oversight of material climate-risks and any risks that have materially impacted, or are reasonably likely to have a material impact on, its business strategy, results of operations or financial condition. Additionally, the final rule requires disclosure of material Scope 1 and Scope 2 greenhouse gas emissions, material climate targets and goals and certain disclosures related to severe weather events and other natural conditions. Such disclosures will be required in a registrant’s annual reporting under a phased-in approach beginning with annual reports for the year ending December 31, 2025 for calendar-year-end large accelerated filers, such as M&T. On April 4, 2024, the SEC issued an order to stay the final rule pending the completion of judicial review by the United States Court of Appeals for the Eighth Circuit.
Recent Accounting Developments
A discussion of the Company's significant accounting policies and critical accounting estimates can be found in M&T's 2023 Annual Report. A summary of recent accounting developments is included in note 1 of Notes to Financial Statements.

Management’s Discussion and Analysis of Financial Condition and Results of Operations and other sections of this quarterly report contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and the rules and regulations of the SEC. Any statement that does not describe historical or current facts is a forward-looking statement, including statements based on current expectations, estimates and projections about the Company’s business, and management's beliefs and assumptions.
Statements regarding the potential effects of events or factors specific to the Company and/or the financial industry as a whole, as well as national and global events generally, on the Company's business, financial condition, liquidity and results of operations may constitute forward-looking statements. Such statements are subject to the risk that the actual effects may differ, possibly materially, from what is reflected in those forward-looking statements due to factors and future developments that are uncertain, unpredictable and in many cases beyond the Company's control.
Forward-looking statements are typically identified by words such as "believe," "expect," "anticipate," "intend," "target," "estimate," "continue," or "potential," by future conditional verbs such as "will," "would," "should," "could," or "may," or by variations of such words or by similar expressions. These statements are not guarantees of

future performance and involve certain risks, uncertainties and assumptions which are difficult to predict and may cause actual outcomes to differ materially from what is expressed or forecasted.
While there can be no assurance that any list of risks and uncertainties is complete, important factors that could cause actual outcomes and results to differ materially from those contemplated by forward-looking statements include the following, without limitation: economic conditions and growth rates, including inflation and market volatility; events and developments in the financial services industry, including industry conditions; changes in interest rates, spreads on earning assets and interest-bearing liabilities, and interest rate sensitivity; prepayment speeds, loan originations, loan concentrations by type and industry, credit losses and market values on loans, collateral securing loans, and other assets; sources of liquidity; levels of client deposits; ability to contain costs and expenses; changes in the Company's credit ratings; the impact of the People's United acquisition; domestic or international political developments and other geopolitical events, including international conflicts and hostilities; changes and trends in the securities markets; common shares outstanding, common stock price volatility; fair value of and number of stock-based compensation awards to be issued in future periods; the impact of changes in market values on trust-related revenues; federal, state or local legislation and/or regulations affecting the financial services industry, or M&T and its subsidiaries individually or collectively, including tax policy; regulatory supervision and oversight, including monetary policy and capital requirements; governmental and public policy changes; political conditions, either nationally or in the states in which M&T and its subsidiaries do business; the outcome of pending and future litigation and governmental proceedings, including tax-related examinations and other matters; changes in accounting policies or procedures as may be required by the Financial Accounting Standards Board, regulatory agencies or legislation; increasing price, product and service competition by competitors, including new entrants; technological developments and changes; the ability to continue to introduce competitive new products and services on a timely, cost-effective basis; the mix of products and services; protection and validity of intellectual property rights; reliance on large customers; technological, implementation and cost/financial risks in large, multi-year contracts; continued availability of financing; financial resources in the amounts, at the times and on the terms required to support M&T and its subsidiaries' future businesses; and material differences in the actual financial results of merger, acquisition, divestment and investment activities compared with M&T's initial expectations, including the full realization of anticipated cost savings and revenue enhancements.
These are representative of the factors that could affect the outcome of the forward-looking statements. In addition, as noted, such statements could be affected by general industry and market conditions and growth rates, general economic and political conditions, either nationally or in the states in which the Company does business, and other factors.
The Company provides further detail regarding these risks and uncertainties in its 2023 Annual Report, including in the Risk Factors section of such report, as well as in other SEC filings. Forward-looking statements speak only as of the date they are made, and the Company assumes no duty and does not undertake to update forward-looking statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Incorporated by reference to the discussion contained in Part I, Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations," under the captions "Liquidity Risk," "Market Risk and Interest Rate Sensitivity" and "Capital."
Item 4. Controls and Procedures.
(a) Evaluation of disclosure controls and procedures. Based upon their evaluation of the effectiveness of M&T’s disclosure controls and procedures (as defined in Exchange Act rules 13a-15(e) and 15d-15(e)), René F. Jones, Chairman of the Board and Chief Executive Officer, and Daryl N. Bible, Senior Executive Vice President and Chief Financial Officer, concluded that M&T’s disclosure controls and procedures were effective as of September 30, 2024.
(b) Changes in internal control over financial reporting. M&T regularly assesses the adequacy of its internal control over financial reporting and enhances its controls in response to internal control assessments and internal and external audit and regulatory recommendations. No changes in internal control over financial reporting have been identified in connection with the evaluation of disclosure controls and procedures during the quarter ended September 30, 2024 that have materially affected, or are reasonably likely to materially affect, M&T’s internal control over financial reporting.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings.
M&T and its subsidiaries are subject in the normal course of business to various pending and threatened legal proceedings and other matters in which claims for monetary damages are asserted. On an on-going basis management, after consultation with legal counsel, assesses the Company’s liabilities and contingencies in connection with such proceedings. For those matters where it is probable that the Company will incur losses and the amounts of the losses can be reasonably estimated, the Company records an expense and corresponding liability in its consolidated financial statements. To the extent the pending or threatened litigation could result in exposure in excess of that liability, the amount of such excess is not currently estimable. Although not considered probable, the range of reasonably possible losses for such matters in the aggregate, beyond the existing recorded liability, was between $0 and $25 million as of September 30, 2024. Although the Company does not believe that the outcome of pending legal matters will be material to the Company’s consolidated financial position, it cannot rule out the possibility that such outcomes will be material to the consolidated results of operations for a particular reporting period in the future.
Item 1A. Risk Factors.
There have been no material changes in risk factors relating to the Company to those disclosed in response to Part I, Item 1A of M&T's 2023 Annual Report.
