WSFS Bank has two wholly-owned subsidiaries: Beneficial Equipment Finance Corporation (BEFC) and 1832 Holdings, Inc. , and one majority-owned subsidiary, NewLane Finance Company (NewLane Finance ® ). On January 1, 2023, WSFS completed the merger and brand conversion of WSFS Capital Management, LLC (West Capital) and Cypress Capital Management, LLC and renamed the combined entity Bryn Mawr Capital Management, LLC. BMCM is registered as an investment advisor with the U.S. Securities and Exchange Commission and is a wholly-owned subsidiary of WSFS. Overview Founded in 1832, the Bank is one of the ten oldest bank and trust companies continuously operating under the same name in the United States (U.S.). The Company provides residential and commercial real estate, commercial and consumer lending services, as well as consumer deposit and treasury management services. The Company's core banking business is commercial lending funded primarily by customer-generated deposits. In addition, the Company offers a variety of wealth management and trust services to individuals, institutions and corporations. The Federal Deposit Insurance Corporation (FDIC) insures the customers’ deposits to their legal maximums. The Company serves its customers primarily from 116 offices located in Pennsylvania (59 ), Delaware ( 40) , New Jersey (14 ), Florida (1), Nevada (1) and Virginia (1) , its ATM network, website at www.wsfsbank.com and mobile app. Information on the website is not incorporated by reference into this Quarterly Report on Form 10-Q. Basis of Presentation In preparing the unaudited Consolidated Financial Statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Amounts subject to significant estimates include the allowance for credit losses (including loans and leases held for investment, investment securities available-for-sale and held-to-maturity), lending-related commitments, goodwill, intangible assets, post-retirement benefit obligations, the fair value of financial instruments, and income taxes. Among other effects, changes to these estimates could result in future impairments of investment securities, goodwill and intangible assets, the establishment of additional allowance and lending-related commitment reserves, changes in the fair value of financial instruments, as well as increased post-retirement benefits and income tax expense. The Company's accounting and reporting policies conform to Generally Accepted Accounting Principles in the U.S. (GAAP), prevailing practices within the banking industry for interim financial information and Rule 10-01 of SEC Regulation S-X (Rule 10-01). Rule 10-01 does not require us to include all information and notes that would be required in audited financial statements. Certain prior period amounts have been reclassified to conform with current period presentation. Operating results for the periods presented are not necessarily indicative of the results that may be expected for any future quarters or for the year ending December 31, 2023. These unaudited, interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in the Annual Report on Form 10-K for the year ended December 31, 2022 (the 2022 Annual Report on Form 10-K) that was filed with the SEC on February 28, 2023 and is available at www.sec.gov or on the website at www.wsfsbank.com . All significant intercompany accounts and transactions were eliminated in consolidation.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES SIGNIFICANT ACCOUNTING POLICIES: The significant accounting policies used in preparation of the Consolidated Financial Statements are disclosed in the Company's 2022 Annual Report on Form 10-K. Those significant accounting policies remain unchanged at September 30, 2023, except for the following: Past Due and Nonaccrual Loans Past due loans are defined as loans contractually past due 90 days or more as to principal or interest payments. Past due loans 90 days or more that remain in accrual status are considered well secured and in the process of collection. Nonaccruing loans are those on which the accrual of interest has ceased. Loans are placed on nonaccrual status immediately if, in the opinion of the Company, collection is doubtful, or when principal or interest is past due 90 days or more and the loan is not well secured and in the process of collection. Interest accrued but not collected at the date a loan is placed on nonaccrual status is reversed and charged against interest income. In addition, the amortization of net deferred loan fees is suspended when a loan is placed on nonaccrual status. Subsequent cash receipts are applied either to the outstanding principal balance or recorded as interest income, depending on the Company’s assessment of the ultimate collectability of principal and interest. Loans are returned to accrual status when the Company assesses that the borrower has the ability to make all principal and interest payments in accordance with the terms of the loan (i.e., a consistent repayment record, generally six consecutive payments, has been demonstrated). For loans greater than 90 days past due, unless loans are well-secured and collection is imminent, their respective reserves are generally charged off once the loss has been confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged off and expected to be charged off. A loan, for which the terms have been modified in the current reporting period in the form of principal forgiveness, an interest rate reduction, an other than-insignificant payment delay, or a term extension to a borrower experiencing financial difficulty, is considered a troubled loan. The assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Principal balances are generally not forgiven when a loan is modified as a troubled loan. Nonaccruing troubled loans remain in nonaccrual status until there has been a period of sustained repayment performance demonstrated and repayment is reasonably assured. Since the effect of most troubled loans are already included in the Company’s estimate of expected credit losses, a change to the allowance for credit losses is generally not recorded upon modification. For additional detail regarding past due and nonaccrual loans, see Note 7. Allowance for Credit Losses - Loans and Leases The Company establishes its allowance in accordance with guidance provided in ASC 326, Financial Instruments - Credit Losses . The allowance for credit losses includes quantitative and qualitative factors that comprise the Company's current estimate of expected credit losses, including the Company's portfolio mix and segmentation, modeling methodology, historical loss experience, relevant available information from internal and external sources relating to qualitative adjustment factors, prepayment speeds and reasonable and supportable forecasts about future economic conditions. The Company's portfolio segments, established based on similar risk characteristics and loss behaviors, are: • Commercial Loans and Leases: Commercial and industrial - real estate secured, commercial and industrial - non-real estate secured, owner-occupied commercial, commercial mortgages, construction and commercial small business leases, and • Residential and Consumer Loans: Residential mortgage, equity secured lines and loans, installment loans, unsecured lines of credit, originated education loans and previously acquired education loans. Expected credit losses are net of expected recoveries and estimated over the contractual term, adjusted for expected prepayments. The contractual term excludes any extensions, renewals and modifications unless they are not unconditionally cancellable. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Expected prepayments are based on historical experience and considers adjustments for current and future economic conditions. The allowance includes two primary components: (i) an allowance established on loans which share similar risk characteristics collectively evaluated for credit losses (collective basis) and (ii) an allowance established on loans which do not share similar risk characteristics with any loan segment and are individually evaluated for credit losses (individual basis). Loans that share similar risk characteristics are collectively reviewed for credit loss and are evaluated based on historical loss experience, adjusted for current economic conditions and future economic forecasts. Estimated losses are determined differently for commercial and residential and consumer loans, and each portfolio segment is further segmented by internally assessed risk ratings. The Company uses a single scenario third-party economic forecast to adjust the calculated historical loss rates of the portfolio segments to incorporate the effects of current and future economic conditions. The Company's economic forecast considers the general health of the economy, the interest rate environment, real estate pricing and market risk. The Company's forecast extends out 6 quarters (the forecast period) and reverts to the historical loss rates on a straight-line basis over 4 quarters (the reversion period) as it believes this to be reasonable and supportable in the current environment. The economic forecast and reversion periods will be evaluated periodically by the Company and updated as appropriate. The historical loss rates for commercial loans are estimated by determining the probability of default (PD) and expected loss given default (LGD) and are applied to the loans' exposure at default. The probability of default is calculated based on the historical rate of migration to an event of credit loss during the look-back period. The historical loss rates for consumer loans is calculated based on average net loss rates over the same look-back period. The current look-back period is 51 quarters which ensures historical loss rates are adequately considering losses within a full credit cycle. Loans that do not share similar risk characteristics with any loan segments are evaluated on an individual basis. These loans, which may include troubled loans, are not included in the collective basis evaluation. When it is probable the Company will not collect all principal and interest due according to their contractual terms, which is assessed based on the credit characteristics of the loan and/or payment status, these loans are individually reviewed and measured for potential credit loss. The amount of the potential credit loss is measured using any of the following three methods: (i) the present value of expected future cash flows discounted at the loan’s effective interest rate; (ii) the fair value of collateral if the loan is collateral dependent; or (iii) the loan’s observable market price. If the measured fair value of the loan is less than the amortized cost basis of the loan, an allowance for credit loss is recorded. For collateral dependent loans, the expected credit losses at the individual asset level are the difference between the collateral's fair value (less cost to sell) and the amortized cost. Qualitative adjustment factors consider various internal and external conditions which are allocated among loan segments and take into consideration: • Current underwriting policies, staff and portfolio concentrations, • Risk rating accuracy, credit and administration, • Internal risk emergence (including internal trends of delinquency, and criticized loans by segment), • Economic forecasts and conditions - locally and nationally (including market trends impacting collateral values), which is separate from or in addition to the third-party economic forecast described above, and • Competitive environment, as it could impact loan structure and underwriting. These factors are based on their relative standing compared to the period in which historical losses are used in quantitative reserve estimates and current directional trends, and reasonable and supportable forecasts. Qualitative factors can add to or subtract from quantitative reserves. The Company's loan officers and risk managers meet at least quarterly to discuss and review the conditions and risks associated with individual problem loans. In addition, various regulatory agencies periodically review the Company's loan ratings and allowance for credit losses and the Bank's internal loan review department performs recurring loan reviews. Accrued interest receivable on loans is excluded from the estimate of credit losses and is included in Accrued interest receivable on the unaudited Consolidated Statements of Financial Condition. For additional detail regarding the allowance for credit losses and the provision for credit losses, see Note 7. RECENT ACCOUNTING PRONOUNCEMENTS Accounting Guidance Adopted in 2023 ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures: In March 2022, the FASB issued ASU No. 2022-02 , Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The guidance eliminates the accounting guidance for troubled debt restructurings by creditors (ASC 310-40) while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. The guidance also requires that an entity disclose current-period write-offs by year of origination for financing receivables and net investments in leases within the scope of Topic 326. The Company adopted this guidance prospectively on January 1, 2023. For further details on the impact of the adoption and accounting policies, see updated Significant Accounting Policies, as described above, and troubled loans disclosures in Note 7 - Allowance for Credit Losses and Credit Quality Information . Accounting Guidance Pending Adoption as of September 30, 2023 ASU No. 2023-01, Leases (Topic 842) Common Control Agreements: In March 2023, the FASB issued ASU No. 2023-01 , Leases (Topic 842) Common Control Agreements. The amendment clarifies the accounting for leasehold improvements associated with common control leases by allowing the lessee to amortize the leasehold improvements over the useful life of the common control group’s use of the underlying asset, regardless of the lease term. The guidance is effective for fiscal years beginning after December 15, 2023. Early adoption is permitted. Adoption is required on a modified retrospective basis, consistent with the Company's adoption of Topic 842. The Company does not expect this update to have a material impact on the Consolidated Financial Statements. ASU No. 2023-02, Investments—Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method: In March 2023, The FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method . The amendments permit reporting entities to elect to account for any equity investments in a tax credit program using the proportional amortization method if certain conditions are met. The amendments are effective for fiscal years beginning after December 15, 2023. Early adoption is permitted. Adoption is required on a prospective, modified retrospective, or retrospective basis depending on the amendment. The Company does not expect this update to have a material impact on the Consolidated Financial Statements.

NONINTEREST INCOME	3. NONINTEREST INCOME Credit/debit card and ATM income The following table presents the components of credit/debit card and ATM income: Three Months Ended September 30, Nine Months Ended September 30, (Dollars in thousands) 2023 2022 2023 2022 Bailment fees $ 9,982 $ 6,306 $ 28,051 $ 13,105 Interchange fees 3,885 3,870 11,764 11,859 Other card and ATM fees 1,002 817 2,845 2,482 Total credit/debit card and ATM income $ 14,869 $ 10,993 $ 42,660 $ 27,446 Credit/debit card and ATM income is composed of bailment fees, interchange fees, and other card and ATM fees. Bailment fees are earned from bailment arrangements with customers. Bailment arrangements are legal relationships in which property is delivered to another party without a transfer of ownership. The party who transferred the property (the bailor) retains ownership interest of the property. In the event that the bailee files for bankruptcy protection, the property is not included in the bailee's assets. The bailee pays an agreed-upon fee for the use of the bailor's property in exchange for the bailor allowing use of the assets at the bailee's site. Bailment fees are earned from cash that is made available for customers' use at an offsite location, such as cash located in an ATM at a customer's place of business. These fees are typically indexed to a market interest rate. This revenue stream generates fee income through monthly billing for bailment services. Credit/debit card and ATM income also includes interchange fees. Interchange fees are paid by a merchant's bank to a bank that issued a debit or credit card used in a transaction to compensate the issuing bank for the value and benefit the merchant receives from accepting electronic payments. These revenue streams generate fee income at the time a transaction occurs and are recorded as revenue at the time of the transaction. Investment management and fiduciary income The following table presents the components of investment management and fiduciary income: Three Months Ended September 30, Nine Months Ended September 30, (Dollars in thousands) 2023 2022 2023 2022 Trust fees $ 22,062 $ 19,170 $ 64,514 $ 58,658 Wealth management and advisory fees 10,658 10,334 31,061 32,219 Total investment management and fiduciary income $ 32,720 $ 29,504 $ 95,575 $ 90,877 Investment management and fiduciary income is composed of trust fees and wealth management and advisory fees. Trust fees are based on revenue earned from custody, escrow, trustee and trustee related services on structured finance transactions; indenture trustee, administrative agent and collateral agent services to individuals, institutions and corporations; commercial domicile and independent director services; and investment and trustee services to families and individuals. Most fees are flat fees, except for a portion of personal and corporate trustee fees where the Company earns a percentage on the assets under management or assets held within a trust. This revenue stream primarily generates fee income through monthly, quarterly and annual billings for services provided. Wealth management and advisory fees consists of fees from Bryn Mawr Trust (excluding BMT-DE), BMCM, Powdermill ® , and WSFS Wealth ® Investments. Wealth management and advisory fees are based on revenue earned from services including asset management, financial planning, family office, and brokerage. The fees are based on the market value of assets, are assessed as a flat fee, or are brokerage commissions. This revenue stream primarily generates fee income through monthly, quarterly and annual billings for the services. Deposit service charges The following table presents the components of deposit service charges: Three Months Ended September 30, Nine Months Ended September 30, (Dollars in thousands) 2023 2022 2023 2022 Service fees $ 4,382 $ 3,933 $ 12,833 $ 11,789 Return and overdraft fees 1,851 2,164 5,218 5,835 Other deposit service fees 301 165 799 534 Total deposit service charges $ 6,534 $ 6,262 $ 18,850 $ 18,158 Deposit service charges includes revenue earned from core deposit products, certificates of deposit, and brokered deposits. The Company generates fee revenues from deposit service charges primarily through service charges and overdraft fees. Service charges consist primarily of monthly account maintenance fees, treasury management fees, foreign ATM fees and other maintenance fees. All of these revenue streams generate fee income through service charges for monthly account maintenance and similar items, transfer fees, late fees, overlimit fees, and stop payment fees. Revenue is recorded at the time of the transaction. Other income The following table presents the components of other income: Three Months Ended September 30, Nine Months Ended September 30, (Dollars in thousands) 2023 2022 2023 2022 Managed service fees $ 5,301 $ 4,866 $ 15,316 $ 13,091 Currency preparation 1,331 1,104 3,955 2,904 ATM loss protection 643 681 1,938 1,963 Capital markets revenue 3,581 793 8,170 5,738 Miscellaneous products and services (1) 3,122 5,408 4,381 17,429 Total other income $ 13,978 $ 12,852 $ 33,760 $ 41,125 (1) Includes commissions income from BMT Insurance Advisors (BMTIA) in 2022. The BMTIA business was sold at the end of the second quarter of 2022. Other income consists of managed service fees, which are primarily courier fees related to treasury management, currency preparation, ATM loss protection, capital markets revenue, and other miscellaneous products and services offered by the Bank. These fees are primarily generated through monthly billings or at the time of the transaction. Capital markets revenue consists of fees related to interest rate swaps, risk participation agreements, foreign exchange contracts, letters of credit, and trade finance products and services offered by the Bank. Through its subsidiary BMTIA, the Bank earned commissions from the sale of insurance policies, which are generally calculated as a percentage of the policy premium, and contingent income, which is calculated based on the volume and performance of the policies held by each carrier. Obligations for the sale of insurance policies are generally satisfied at the point in time which the policy is executed and are recognized at the point in time in which the amounts are known and collection is reasonably assured. Performance metrics for contingent income are generally satisfied over time, not exceeding one year, and are recognized at the point in time in which the amounts are known and collection is reasonably assured. The Company's contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices charged to customers. Practical expedients and exemptions The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which it has the right to invoice for services performed.

Credit Quality Indicators Below is a description of each of the risk ratings for all commercial loans: • Pass . These borrowers currently show no indication of deterioration or potential problems and their loans are considered fully collectible. • Special Mention. These borrowers have potential weaknesses that deserve management’s close attention. Borrowers in this category may be experiencing adverse operating trends, for example, declining revenues or margins, high leverage, tight liquidity, or increasing inventory without increasing sales. These adverse trends can have a potential negative effect on the borrower’s repayment capacity. These assets are not adversely classified and do not expose the Bank to significant risk that would warrant a more severe rating. Borrowers in this category may also be experiencing significant management problems, pending litigation, or other structural credit weaknesses. • Substandard or Lower . These borrowers have well-defined weaknesses that require extensive oversight by management. Borrowers in this category may exhibit one or more of the following: inadequate debt service coverage, unprofitable operations, insufficient liquidity, high leverage, and weak or inadequate capitalization. Relationships in this category are not adequately protected by the sound financial worth and paying capacity of the obligor or the collateral pledged on the loan, if any. A distinct possibility exists that the Bank will sustain some loss if the deficiencies are not corrected. In addition, some borrowers in this category could have the added characteristic that the possibility of loss is extremely high. Current circumstances in the credit relationship make collection or liquidation in full highly questionable. Such impending events include: perfecting liens on additional collateral, obtaining collateral valuations, an acquisition or liquidation preceding, proposed merger, or refinancing plan. Residential and Consumer Loans The residential and consumer loan portfolios are monitored on an ongoing basis using delinquency information and loan type as credit quality indicators. These credit quality indicators are assessed in the aggregate in these relatively homogeneous portfolios. Loans that are greater than 90 days past due are generally considered nonperforming and placed on nonaccrual status.

Troubled Loans The Company offers loan modifications to commercial and consumer borrowers that may result in a payment delay, interest rate reduction, term extension, principal forgiveness, or combination thereof. Loan modifications are offered on a case-by-case basis and are generally term extension, payment delay, and interest rate reduction modification types. Forbearance (due to hardship) programs result in modification types including payment delay and/or term extension. In addition, certain reorganization bankruptcy judgments may result in interest rate reduction, term extension, or principal forgiveness modification types. The following table shows the amortized cost basis at the end of the reporting period of troubled loans, disaggregated by portfolio segment and type of modification granted.

(2) Represents the weighted-average decrease in the contractual interest rate on the modified loans. (3) Represents the percentage of loans deferred over the total loan portfolio excluding reverse mortgages at fair value. As of September 30, 2023, the Company had commitments to extend credit of $4.8 million to borrowers experiencing financial difficulty whose terms had been modified. Upon the Company’s determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount. The following table shows the amortized cost of loans that received a term extension modification that had a payment default during the period and were modified in the 12 months before default to borrowers experiencing financial difficulty as of September 30, 2023.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	9. GOODWILL AND INTANGIBLE ASSETS In accordance with ASC 805, Business Combinations (ASC 805) and ASC 350, Intangibles - Goodwill and Other (ASC 350), all assets acquired and liabilities assumed in purchase acquisitions, including goodwill, indefinite-lived intangibles and other intangibles are recorded at fair value as of acquisition date. WSFS performs its annual goodwill impairment test on October 1 or more frequently if events and circumstances indicate that the fair value of a reporting unit is less than its carrying value. In between annual tests, management performs a qualitative review of goodwill quarterly as part of the Company's review of the overall business to ensure no events or circumstances have occurred that would impact its goodwill evaluation. During the nine months ended September 30, 2023, management determined based on its qualitative assessment that the fair values of our reporting units exceeded their carrying values, and no goodwill impairment existed during the nine months ended September 30, 2023.

Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES OF FINANCIAL ASSETS AND LIABILITIES	12. FAIR VALUE DISCLOSURES OF FINANCIAL ASSETS AND LIABILITIES FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES ASC 820-10, Fair Value Measurement (ASC 820-10) defines fair value 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. ASC 820-10 establishes a fair value hierarchy that prioritizes the use of inputs used in valuation methodologies into the following three levels: • Level 1: Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available. • Level 2: Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets; inputs to the valuation methodology include quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs to the valuation methodology that are derived principally from or can be corroborated by observable market data by correlation or other means. • Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Level 3 assets and liabilities include financial instruments whose value is determined using discounted cash flow methodologies, as well as instruments for which the determination of fair value requires significant management judgment or estimation. The following tables present financial instruments carried at fair value as of September 30, 2023 and December 31, 2022 by level in the valuation hierarchy (as described above): September 30, 2023 (Dollars in thousands) Quoted Significant Significant Total Fair Assets measured at fair value on a recurring basis: Available-for-sale securities: CMO $ — $ 454,664 $ — $ 454,664 FNMA MBS — 2,913,412 — 2,913,412 FHLMC MBS — 110,719 — 110,719 GNMA MBS — 42,751 — 42,751 GSE agency notes — 169,995 — 169,995 Other assets — 203,083 23 203,106 Total assets measured at fair value on a recurring basis $ — $ 3,894,624 $ 23 $ 3,894,647 Liabilities measured at fair value on a recurring basis: Other liabilities $ — $ 196,821 $ 14,482 $ 211,303 Assets measured at fair value on a nonrecurring basis: Other investments $ — $ — $ 21,741 $ 21,741 Other real estate owned — — 298 298 Loans held for sale — 36,658 — 36,658 Total assets measured at fair value on a nonrecurring basis $ — $ 36,658 $ 22,039 $ 58,697 December 31, 2022 (Dollars in thousands) Quoted Significant Significant Total Fair Assets measured at fair value on a recurring basis: Available-for-sale securities: CMO $ — $ 506,380 $ — $ 506,380 FNMA MBS — 3,250,258 — 3,250,258 FHLMC MBS — 121,999 — 121,999 GNMA MBS — 36,138 — 36,138 GSE agency notes — 178,285 — 178,285 Other assets — 156,912 81 156,993 Total assets measured at fair value on a recurring basis $ — $ 4,249,972 $ 81 $ 4,250,053 Liabilities measured at fair value on a recurring basis: Other liabilities $ — $ 156,520 $ 17,102 $ 173,622 Assets measured at fair value on a nonrecurring basis Other investments $ — $ — $ 26,120 $ 26,120 Other real estate owned — — 833 833 Loans held for sale — 42,985 — 42,985 Total assets measured at fair value on a nonrecurring basis $ — $ 42,985 $ 26,953 $ 69,938 Fair value is based on quoted market prices, where available. If such quoted market prices are not available, fair value is based on internally developed models or obtained from third parties that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include unobservable parameters. The Company's valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While the Company believes its valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Available-for-sale securities Securities classified as available-for-sale are reported at fair value using Level 2 inputs. The Company believes that this Level 2 designation is appropriate under ASC 820-10, as these securities are GSEs and GNMA securities with almost all fixed income securities, none are exchange traded, and all are priced by correlation to observed market data. For these securities the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, U.S. government and agency yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the security’s terms and conditions, among other factors. Other investments Other investments includes equity investments without readily determinable fair values and equity method investments, which are categorized as Level 3. The Company’s equity investments without readily determinable fair values are held at cost, and are adjusted for any observable transactions during the reporting period and its equity method investments are initially recorded at cost based on the Company’s percentage ownership in the investee, and are adjusted to reflect the recognition of the Company’s proportionate share of income or loss of the investee based on the investee’s earnings. Other real estate owned Other real estate owned consists of loan collateral which has been repossessed through foreclosure or other measures. Initially, foreclosed assets are recorded at the fair value of the collateral less estimated selling costs. Subsequent to foreclosure, valuations are updated periodically and the assets may be marked down further, reflecting a new cost basis. The fair value of other real estate owned was estimated using Level 3 inputs based on appraisals obtained from third parties. Loans held for sale The fair value of loans held for sale is based on estimates using Level 2 inputs. These inputs are based on pricing information obtained from wholesale mortgage banks and brokers and applied to loans with similar interest rates and maturities. Other assets Other assets include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, and risk participation agreements. Valuation of interest rate products is obtained from an independent pricing service and also from the derivative counterparty. Valuation of the derivative related to the residential mortgage held for sale loan pipeline is based on valuation of the loans held for sale portfolio as described above in Loans held for sale . Valuation of risk participation agreements are obtained from an independent pricing service. Other liabilities Other liabilities include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, foreign exchange forward contracts, risk participation agreements, and derivative related to the sale of certain Visa Class B common shares. Valuation of interest rate products is obtained from an independent pricing service and also from the derivative counterparty. Valuation of the derivative related to the residential mortgage held for sale loan pipeline is based on valuation of the loans held for sale portfolio as described above in Loans held for sale. Valuation of foreign exchange forward contracts and risk participation agreements are obtained from an independent pricing service. Valuation of the derivative related to the sale of certain Visa Class B common shares is based on: (i) the agreed upon graduated fee structure; (ii) the length of time until the resolution of the Visa covered litigation; and (iii) the estimated impact of dilution in the conversion ratio of Class B shares resulting from changes in the Visa covered litigation. FAIR VALUE OF FINANCIAL INSTRUMENTS The reported fair values of financial instruments are based on a variety of factors. In certain cases, fair values represent quoted market prices for identical or comparable instruments. In other cases, fair values have been estimated based on assumptions regarding the amount and timing of estimated future cash flows that are discounted to reflect current market rates and varying degrees of risk. Accordingly, the fair values may not represent actual values of the financial instruments that could have been realized as of period-end or that will be realized in the future. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: Cash, cash equivalents, and restricted cash For cash and short-term investment securities, including due from banks, federal funds sold or purchased under agreements to resell and interest-bearing deposits with other banks, the carrying amount is a reasonable estimate of fair value. Investment securities Investment securities include debt securities classified as held-to-maturity or available-for-sale. Fair value is estimated using quoted prices for similar securities, which the Company obtains from a third party vendor. The Company uses one of the largest providers of securities pricing to the industry and management periodically assesses the inputs used by this vendor to price the various types of securities owned by the Company to validate the vendor’s methodology as described above in available-for-sale securities. Other investments Other investments includes equity investments without readily determinable fair values (see discussion in “Fair Value of Financial Assets and Liabilities” section above). Loans held for sale Loans held for sale are carried at their fair value (see discussion in “Fair Value of Financial Assets and Liabilities” section above). Loans and leases Loans and leases are segregated by portfolio segments with similar financial characteristics. The fair values of loans and leases, with the exception of reverse mortgages, are estimated by discounting expected cash flows using the current rates at which similar loans would be made to borrowers with comparable credit ratings and for similar remaining maturities. The fair values of reverse mortgages are based on the net present value of the expected cash flows using a discount rate specific to the reverse mortgages portfolio. The fair value of nonperforming loans is based on recent external appraisals of the underlying collateral, if the loan is collateral dependent. Estimated cash flows, discounted using a rate commensurate with current rates and the risk associated with the estimated cash flows, are used if appraisals are not available. This technique does contemplate an exit price. Stock in the Federal Home Loan Bank (FHLB) of Pittsburgh The fair value of FHLB stock is assumed to be equal to its cost basis, since the stock is non-marketable but redeemable at its par value. Accrued interest receivable The carrying amounts of interest receivable approximate fair value. Other assets Other assets include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, and risk participation agreements (see discussion in “Fair Value of Financial Assets and Liabilities” section above). Deposits The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, money market and interest-bearing demand deposits, is assumed to be equal to the amount payable on demand. The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using rates currently offered for deposits with comparable remaining maturities. Borrowed funds Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt. Off-balance sheet instruments The fair value of off-balance sheet instruments, including swap guarantees of $7.7 million at September 30, 2023 and $10.4 million at December 31, 2022, respectively, and standby letters of credit, approximates the recorded net deferred fee amounts. Because letters of credit are generally not assignable by either the Company or the borrower, they only have value to the Company and the borrower. In determining the fair value of the swap guarantees, the Company assesses the underlying credit risk exposure for each borrower in a paying position to the third-party financial institution. Accrued interest payable The carrying amounts of interest payable approximate fair value. Other liabilities Other liabilities include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, foreign exchange forward contracts, risk participation agreements, and derivative related to the sale of certain Visa Class B common shares (see discussion in “Fair Value of Financial Assets and Liabilities” section above).

DERIVATIVE FINANCIAL INSTRUMENTS	13. DERIVATIVE FINANCIAL INSTRUMENTS Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both economic conditions and its business operations. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities. The Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions. The Company does not use derivative financial instruments for trading purposes.

To accomplish this objective, the Company primarily uses interest rate options, including floors, caps, collars, or swaps as part of its interest rate risk management strategy. Interest rate options designated as cash flow hedges involve the receipt of fixed amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company has agreements with certain derivative counterparties that contain a provision under which, if it defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company also has agreements with certain derivative counterparties that contain a provision where if it fails to maintain its status as a well-capitalized or adequately capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. During 2023, the Company purchased six interest rate floors at a premium of $9.7 million with an aggregate notional amount of $500.0 million to hedge variable cash flows associated with a variable rate loan pool through the third quarter of 2026. Changes to the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecast transaction affects earnings. If the Company determines that a cash flow hedge is no longer highly effective, future changes in the fair value of the hedging instrument would be reported in earnings. As of September 30, 2023, the Company determined the cash flow hedges remain highly effective. During the three and nine months ended September 30, 2023, $0.4 million and $0.6 million, respectively, of amortization expense on the premium was reclassified into interest income. The Company does not expect any unrealized gains or losses related to cash flow hedges to be reclassified into earnings in the next twelve months. In 2020, the Company terminated its three interest rate swaps that were designated as cash flow hedges for a net gain of $1.3 million, recognized in accumulated other comprehensive income. The derivatives were used to hedge the variable cash flows associated with a variable rate loan pool. Hedge accounting was discontinued, and the net gain in accumulated comprehensive income is reclassified into earnings when the transaction affects earnings. As the underlying hedged transaction continued to be probable, the remaining net gain for the three and nine months ended September 30, 2023, of less than $0.1 million and $0.1 million was reclassified into interest income, respectively. As of September 30, 2023, this gain has been fully recognized and reclassified to interest income. Derivatives Not Designated as Hedging Instruments: Customer Derivatives – Interest Rate Swaps The Company enters into interest rate swaps with commercial loan customers wishing to manage interest rate risk. The Company then enters into corresponding swap agreements with swap dealer counterparties to economically hedge the exposure arising from these contracts. The interest rate swaps with both the customers and third parties are not designated as hedges under ASC 815, Derivatives and Hedging (ASC 815) and are marked to market through earnings. As the interest rate swaps are structured to offset each other, changes to the underlying benchmark interest rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by ASC 820. As of September 30, 2023, there were no fair value adjustments related to credit quality. Derivative Financial Instruments from Mortgage Banking Activities Derivative financial instruments related to mortgage banking activities are recorded at fair value and are not designated as accounting hedges. This includes commitments to originate certain fixed-rate residential mortgage loans to customers, also referred to as interest rate lock commitments. The Company may also enter into forward sale commitments to sell loans to investors at a fixed price at a future date and trade asset-backed securities to mitigate interest rate risk. Foreign Exchange Forward Contracts The Company enters into foreign exchange forward contracts (FX forwards) with customers to exchange one currency for another on an agreed date in the future at an agreed exchange rate. The Corporation then enters into corresponding FX forwards with swap dealer counterparties to economically hedge its exposure on the exchange rate component of the customer agreements. The FX forwards with both the customers and third parties are not designated as hedges under ASC 815 and are marked to market through earnings. Exposure to gains and losses on these contracts increase or decrease over their respective lives as currency exchange and interest rates fluctuate. As the FX forwards are structured to offset each other, changes to the underlying term structure of currency exchange rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by ASC 820. As of September 30, 2023, there were no fair value adjustments related to credit quality. Risk Participation Agreements The Company may enter into a risk participation agreement (RPA) with another institution as a means to assume a portion of the credit risk associated with a loan structure which includes a derivative instrument, in exchange for fee income commensurate with the risk assumed. This type of derivative is referred to as an “RPA sold.” In addition, in an effort to reduce the credit risk associated with an interest rate swap agreement with a borrower for whom the Corporation has provided a loan structured with a derivative, the Corporation may purchase an RPA from an institution participating in the facility in exchange for a fee commensurate with the risk shared. This type of derivative is referred to as an “RPA purchased.” Swap Guarantees The Company entered into agreements with one unrelated financial institution whereby that financial institution entered into interest rate derivative contracts (interest rate swap transactions) directly with customers referred to them by the Company. Under the terms of the agreements, the financial institution has recourse to us for any exposure created under each swap transaction, only in the event that the customer defaults on the swap agreement and the agreement is in a paying position to the third-party financial institution. This is a customary arrangement that allows us to provide access to interest rate swap transactions for our customers without creating the swap ourselves. These swap guarantees are accounted for as credit derivatives. At September 30, 2023 and December 31, 2022, there were 193 and 209 variable-rate to fixed-rate swap transactions between the third-party financial institutions and the Company's customers, respectively. The initial notional aggregate amount was approximately $0.8 billion at September 30, 2023 and December 31, 2022. At September 30, 2023, the swap transactions remaining maturities ranged from under 1 year to 12 years. At September 30, 2023, none of these customer swaps were in a paying position to third parties, with our swap guarantees having a fair value of $7.7 million. At December 31, 2022, none of these customer swaps were in a paying position to third parties, with the Company's swap guarantees having a fair value of $10.4 million. However, for both periods, none of the Company's customers were in default of the swap agreements. Credit-risk-related Contingent Features The Company has agreements with certain derivative counterparties that contain a provision under which, if it defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company has minimum collateral posting thresholds with certain of its derivative counterparties, and has posted collateral of $5.0 million in cash against its obligations under these agreements which meets or exceeds the minimum collateral posting requirements. If the Company had breached any of these provisions at September 30, 2023, it could have been required to settle its obligations under the agreements at the termination value.

Segment Reporting [Abstract]
SEGMENT INFORMATION	14. SEGMENT INFORMATION As defined in ASC 280, Segment Reporting (ASC 280), an operating segment is a component of an enterprise that engages in business activities from which it may earn revenues and incur expenses, whose operating results are regularly reviewed by the enterprise’s chief operating decision makers to make decisions about resources to be allocated to the segment and assess its performance, and for which discrete financial information is available. The Company evaluates performance based on pretax net income relative to resources used, and allocate resources based on these results. The accounting policies applicable to the Company's segments are those that apply to its preparation of the accompanying unaudited Consolidated Financial Statements. Based on these criteria, the Company has identified three segments: WSFS Bank, Cash Connect ® , and Wealth Management. The WSFS Bank segment provides financial products to commercial and consumer customers. Commercial and Consumer Banking, Commercial Real Estate Lending and other banking business units are operating departments of WSFS Bank. These departments share the same regulators, the same market, many of the same customers and provide similar products and services through the general infrastructure of the Bank. Accordingly, these departments are not considered discrete segments and are appropriately aggregated in the WSFS Bank segment. The Company's Cash Connect ® segment provides ATM vault cash, smart safe and other cash logistics services through strategic partnerships with several of the largest networks, manufacturers and service providers in the ATM industry. Cash Connect ® services non-bank and WSFS-branded ATMs and smart safes nationwide. The balance sheet category Cash in non-owned ATMs includes cash from which fee income is earned through bailment arrangements with customers of Cash Connect ® . The Wealth Management segment provides a broad array of planning and advisory services, investment management, trust services, and credit and deposit products to individual, corporate, and institutional clients through multiple integrated businesses. Bryn Mawr Trust ® is our predominant Private Wealth Management brand, providing advisory, investment management and trustee services to institutions, affluent and high-net-worth individuals. The Bryn Mawr Trust Company of Delaware provides personal trust and fiduciary services to families and individuals across the U.S. and internationally. WSFS Institutional Services ® provides trustee, agency, bankruptcy administration, custodial and commercial domicile services to institutional, corporate clients and special purpose vehicles. Private Wealth Management serves high-net-worth clients and institutions by providing trustee and advisory services, financial planning, customized investment strategies, brokerage products such as annuities and traditional banking services such as credit and deposit products tailored to its clientele. Private Wealth Management includes businesses that operate under the bank’s charter, through a broker/dealer and as a registered investment advisor (RIA). It generates revenue through a percentage fee based on account assets, fee-only arrangements, net interest income and other fee-only services such as estate administration, trust tax planning and custody. Powdermill ® is a multi-family office specializing in providing independent solutions to high-net-worth individuals, families and corporate executives through a coordinated, centralized approach.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	15. COMMITMENTS AND CONTINGENCIES Secondary Market Loan Sales The Company typically sells newly originated residential mortgage loans in the secondary market to mortgage loan aggregators and to GSEs such as FHLMC, FNMA, and on a more limited basis, the FHLB. Loans held for sale are reflected on the unaudited Consolidated Statements of Financial Condition at fair value with changes in the value reflected in the unaudited Consolidated Statements of Income. Gains and losses are recognized at the time of sale. The Company periodically retains the servicing rights on residential mortgage loans sold which results in monthly service fee income. The mortgage servicing rights are included in Intangible assets on the unaudited Consolidated Statements of Financial Condition. Otherwise, the Company sells loans with servicing released on a nonrecourse basis. Rate-locked loan commitments that the Company intends to sell in the secondary market are accounted for as derivatives under ASC 815. The Company does not sell loans with recourse, except for standard loan sale contract provisions covering violations of representations and warranties and, under certain circumstances, early payment default by the borrower. These are customary repurchase provisions in the secondary market for residential mortgage loan sales. These provisions may include either an indemnification from loss or the repurchase of the loans. Repurchases and losses have been rare and no provision is made for losses at the time of sale. There was one repurchase during the nine months ended September 30, 2023 for $0.8 million and two repurchases for $0.8 million during the same period in 2022. Unfunded Lending Commitments At September 30, 2023 and December 31, 2022, the allowance for credit losses of unfunded lending commitments was $12.1 million and $11.9 million, respectively. A provision expense of $0.1 million and $0.2 million was recognized during the three and nine months ended September 30, 2023, respectively, compared to a provision expense of $0.7 million and $0.6 million during the three and nine months ended September 30, 2022, respectively.

LEGAL AND OTHER PROCEEDINGS	17. LEGAL AND OTHER PROCEEDINGS In accordance with the current accounting standards for loss contingencies, the Company establishes reserves for litigation-related matters that arise in the ordinary course of its business activities when it is probable that a loss associated with a claim or proceeding has been incurred and the amount of the loss can be reasonably estimated. Litigation claims and proceedings of all types are subject to many uncertain factors that generally cannot be predicted with assurance. In addition, the Company's defense of litigation claims may result in legal fees, which it expenses as incurred. There were no material changes or additions to other significant pending legal or other proceedings involving the Company other than those arising out of routine operations.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2023
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation In preparing the unaudited Consolidated Financial Statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Amounts subject to significant estimates include the allowance for credit losses (including loans and leases held for investment, investment securities available-for-sale and held-to-maturity), lending-related commitments, goodwill, intangible assets, post-retirement benefit obligations, the fair value of financial instruments, and income taxes. Among other effects, changes to these estimates could result in future impairments of investment securities, goodwill and intangible assets, the establishment of additional allowance and lending-related commitment reserves, changes in the fair value of financial instruments, as well as increased post-retirement benefits and income tax expense. The Company's accounting and reporting policies conform to Generally Accepted Accounting Principles in the U.S. (GAAP), prevailing practices within the banking industry for interim financial information and Rule 10-01 of SEC Regulation S-X (Rule 10-01). Rule 10-01 does not require us to include all information and notes that would be required in audited financial statements. Certain prior period amounts have been reclassified to conform with current period presentation. Operating results for the periods presented are not necessarily indicative of the results that may be expected for any future quarters or for the year ending December 31, 2023. These unaudited, interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in the Annual Report on Form 10-K for the year ended December 31, 2022 (the 2022 Annual Report on Form 10-K) that was filed with the SEC on February 28, 2023 and is available at www.sec.gov or on the website at www.wsfsbank.com . All significant intercompany accounts and transactions were eliminated in consolidation.
Past Due and Nonaccrual Loans and Allowance for Credit Losses - Loans and Leases	Past Due and Nonaccrual Loans Past due loans are defined as loans contractually past due 90 days or more as to principal or interest payments. Past due loans 90 days or more that remain in accrual status are considered well secured and in the process of collection. Nonaccruing loans are those on which the accrual of interest has ceased. Loans are placed on nonaccrual status immediately if, in the opinion of the Company, collection is doubtful, or when principal or interest is past due 90 days or more and the loan is not well secured and in the process of collection. Interest accrued but not collected at the date a loan is placed on nonaccrual status is reversed and charged against interest income. In addition, the amortization of net deferred loan fees is suspended when a loan is placed on nonaccrual status. Subsequent cash receipts are applied either to the outstanding principal balance or recorded as interest income, depending on the Company’s assessment of the ultimate collectability of principal and interest. Loans are returned to accrual status when the Company assesses that the borrower has the ability to make all principal and interest payments in accordance with the terms of the loan (i.e., a consistent repayment record, generally six consecutive payments, has been demonstrated). For loans greater than 90 days past due, unless loans are well-secured and collection is imminent, their respective reserves are generally charged off once the loss has been confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged off and expected to be charged off. A loan, for which the terms have been modified in the current reporting period in the form of principal forgiveness, an interest rate reduction, an other than-insignificant payment delay, or a term extension to a borrower experiencing financial difficulty, is considered a troubled loan. The assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Principal balances are generally not forgiven when a loan is modified as a troubled loan. Nonaccruing troubled loans remain in nonaccrual status until there has been a period of sustained repayment performance demonstrated and repayment is reasonably assured. Since the effect of most troubled loans are already included in the Company’s estimate of expected credit losses, a change to the allowance for credit losses is generally not recorded upon modification. For additional detail regarding past due and nonaccrual loans, see Note 7. Allowance for Credit Losses - Loans and Leases The Company establishes its allowance in accordance with guidance provided in ASC 326, Financial Instruments - Credit Losses . The allowance for credit losses includes quantitative and qualitative factors that comprise the Company's current estimate of expected credit losses, including the Company's portfolio mix and segmentation, modeling methodology, historical loss experience, relevant available information from internal and external sources relating to qualitative adjustment factors, prepayment speeds and reasonable and supportable forecasts about future economic conditions. The Company's portfolio segments, established based on similar risk characteristics and loss behaviors, are: • Commercial Loans and Leases: Commercial and industrial - real estate secured, commercial and industrial - non-real estate secured, owner-occupied commercial, commercial mortgages, construction and commercial small business leases, and • Residential and Consumer Loans: Residential mortgage, equity secured lines and loans, installment loans, unsecured lines of credit, originated education loans and previously acquired education loans. Expected credit losses are net of expected recoveries and estimated over the contractual term, adjusted for expected prepayments. The contractual term excludes any extensions, renewals and modifications unless they are not unconditionally cancellable. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Expected prepayments are based on historical experience and considers adjustments for current and future economic conditions. The allowance includes two primary components: (i) an allowance established on loans which share similar risk characteristics collectively evaluated for credit losses (collective basis) and (ii) an allowance established on loans which do not share similar risk characteristics with any loan segment and are individually evaluated for credit losses (individual basis). Loans that share similar risk characteristics are collectively reviewed for credit loss and are evaluated based on historical loss experience, adjusted for current economic conditions and future economic forecasts. Estimated losses are determined differently for commercial and residential and consumer loans, and each portfolio segment is further segmented by internally assessed risk ratings. The Company uses a single scenario third-party economic forecast to adjust the calculated historical loss rates of the portfolio segments to incorporate the effects of current and future economic conditions. The Company's economic forecast considers the general health of the economy, the interest rate environment, real estate pricing and market risk. The Company's forecast extends out 6 quarters (the forecast period) and reverts to the historical loss rates on a straight-line basis over 4 quarters (the reversion period) as it believes this to be reasonable and supportable in the current environment. The economic forecast and reversion periods will be evaluated periodically by the Company and updated as appropriate. The historical loss rates for commercial loans are estimated by determining the probability of default (PD) and expected loss given default (LGD) and are applied to the loans' exposure at default. The probability of default is calculated based on the historical rate of migration to an event of credit loss during the look-back period. The historical loss rates for consumer loans is calculated based on average net loss rates over the same look-back period. The current look-back period is 51 quarters which ensures historical loss rates are adequately considering losses within a full credit cycle. Loans that do not share similar risk characteristics with any loan segments are evaluated on an individual basis. These loans, which may include troubled loans, are not included in the collective basis evaluation. When it is probable the Company will not collect all principal and interest due according to their contractual terms, which is assessed based on the credit characteristics of the loan and/or payment status, these loans are individually reviewed and measured for potential credit loss. The amount of the potential credit loss is measured using any of the following three methods: (i) the present value of expected future cash flows discounted at the loan’s effective interest rate; (ii) the fair value of collateral if the loan is collateral dependent; or (iii) the loan’s observable market price. If the measured fair value of the loan is less than the amortized cost basis of the loan, an allowance for credit loss is recorded. For collateral dependent loans, the expected credit losses at the individual asset level are the difference between the collateral's fair value (less cost to sell) and the amortized cost. Qualitative adjustment factors consider various internal and external conditions which are allocated among loan segments and take into consideration: • Current underwriting policies, staff and portfolio concentrations, • Risk rating accuracy, credit and administration, • Internal risk emergence (including internal trends of delinquency, and criticized loans by segment), • Economic forecasts and conditions - locally and nationally (including market trends impacting collateral values), which is separate from or in addition to the third-party economic forecast described above, and • Competitive environment, as it could impact loan structure and underwriting. These factors are based on their relative standing compared to the period in which historical losses are used in quantitative reserve estimates and current directional trends, and reasonable and supportable forecasts. Qualitative factors can add to or subtract from quantitative reserves. The Company's loan officers and risk managers meet at least quarterly to discuss and review the conditions and risks associated with individual problem loans. In addition, various regulatory agencies periodically review the Company's loan ratings and allowance for credit losses and the Bank's internal loan review department performs recurring loan reviews. Accrued interest receivable on loans is excluded from the estimate of credit losses and is included in Accrued interest receivable on the unaudited Consolidated Statements of Financial Condition. For additional detail regarding the allowance for credit losses and the provision for credit losses, see Note 7.
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Accounting Guidance Adopted in 2023 ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures: In March 2022, the FASB issued ASU No. 2022-02 , Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The guidance eliminates the accounting guidance for troubled debt restructurings by creditors (ASC 310-40) while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. The guidance also requires that an entity disclose current-period write-offs by year of origination for financing receivables and net investments in leases within the scope of Topic 326. The Company adopted this guidance prospectively on January 1, 2023. For further details on the impact of the adoption and accounting policies, see updated Significant Accounting Policies, as described above, and troubled loans disclosures in Note 7 - Allowance for Credit Losses and Credit Quality Information . Accounting Guidance Pending Adoption as of September 30, 2023 ASU No. 2023-01, Leases (Topic 842) Common Control Agreements: In March 2023, the FASB issued ASU No. 2023-01 , Leases (Topic 842) Common Control Agreements. The amendment clarifies the accounting for leasehold improvements associated with common control leases by allowing the lessee to amortize the leasehold improvements over the useful life of the common control group’s use of the underlying asset, regardless of the lease term. The guidance is effective for fiscal years beginning after December 15, 2023. Early adoption is permitted. Adoption is required on a modified retrospective basis, consistent with the Company's adoption of Topic 842. The Company does not expect this update to have a material impact on the Consolidated Financial Statements. ASU No. 2023-02, Investments—Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method: In March 2023, The FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method . The amendments permit reporting entities to elect to account for any equity investments in a tax credit program using the proportional amortization method if certain conditions are met. The amendments are effective for fiscal years beginning after December 15, 2023. Early adoption is permitted. Adoption is required on a prospective, modified retrospective, or retrospective basis depending on the amendment. The Company does not expect this update to have a material impact on the Consolidated Financial Statements.
Fair Value Measurement	Available-for-sale securities Securities classified as available-for-sale are reported at fair value using Level 2 inputs. The Company believes that this Level 2 designation is appropriate under ASC 820-10, as these securities are GSEs and GNMA securities with almost all fixed income securities, none are exchange traded, and all are priced by correlation to observed market data. For these securities the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, U.S. government and agency yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the security’s terms and conditions, among other factors. Other investments Other investments includes equity investments without readily determinable fair values and equity method investments, which are categorized as Level 3. The Company’s equity investments without readily determinable fair values are held at cost, and are adjusted for any observable transactions during the reporting period and its equity method investments are initially recorded at cost based on the Company’s percentage ownership in the investee, and are adjusted to reflect the recognition of the Company’s proportionate share of income or loss of the investee based on the investee’s earnings. Other real estate owned Other real estate owned consists of loan collateral which has been repossessed through foreclosure or other measures. Initially, foreclosed assets are recorded at the fair value of the collateral less estimated selling costs. Subsequent to foreclosure, valuations are updated periodically and the assets may be marked down further, reflecting a new cost basis. The fair value of other real estate owned was estimated using Level 3 inputs based on appraisals obtained from third parties. Loans held for sale The fair value of loans held for sale is based on estimates using Level 2 inputs. These inputs are based on pricing information obtained from wholesale mortgage banks and brokers and applied to loans with similar interest rates and maturities. Other assets Other assets include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, and risk participation agreements. Valuation of interest rate products is obtained from an independent pricing service and also from the derivative counterparty. Valuation of the derivative related to the residential mortgage held for sale loan pipeline is based on valuation of the loans held for sale portfolio as described above in Loans held for sale . Valuation of risk participation agreements are obtained from an independent pricing service. Other liabilities Other liabilities include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, foreign exchange forward contracts, risk participation agreements, and derivative related to the sale of certain Visa Class B common shares. Valuation of interest rate products is obtained from an independent pricing service and also from the derivative counterparty. Valuation of the derivative related to the residential mortgage held for sale loan pipeline is based on valuation of the loans held for sale portfolio as described above in Loans held for sale. Valuation of foreign exchange forward contracts and risk participation agreements are obtained from an independent pricing service. Valuation of the derivative related to the sale of certain Visa Class B common shares is based on: (i) the agreed upon graduated fee structure; (ii) the length of time until the resolution of the Visa covered litigation; and (iii) the estimated impact of dilution in the conversion ratio of Class B shares resulting from changes in the Visa covered litigation. FAIR VALUE OF FINANCIAL INSTRUMENTS The reported fair values of financial instruments are based on a variety of factors. In certain cases, fair values represent quoted market prices for identical or comparable instruments. In other cases, fair values have been estimated based on assumptions regarding the amount and timing of estimated future cash flows that are discounted to reflect current market rates and varying degrees of risk. Accordingly, the fair values may not represent actual values of the financial instruments that could have been realized as of period-end or that will be realized in the future. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: Cash, cash equivalents, and restricted cash For cash and short-term investment securities, including due from banks, federal funds sold or purchased under agreements to resell and interest-bearing deposits with other banks, the carrying amount is a reasonable estimate of fair value. Investment securities Investment securities include debt securities classified as held-to-maturity or available-for-sale. Fair value is estimated using quoted prices for similar securities, which the Company obtains from a third party vendor. The Company uses one of the largest providers of securities pricing to the industry and management periodically assesses the inputs used by this vendor to price the various types of securities owned by the Company to validate the vendor’s methodology as described above in available-for-sale securities. Other investments Other investments includes equity investments without readily determinable fair values (see discussion in “Fair Value of Financial Assets and Liabilities” section above). Loans held for sale Loans held for sale are carried at their fair value (see discussion in “Fair Value of Financial Assets and Liabilities” section above). Loans and leases Loans and leases are segregated by portfolio segments with similar financial characteristics. The fair values of loans and leases, with the exception of reverse mortgages, are estimated by discounting expected cash flows using the current rates at which similar loans would be made to borrowers with comparable credit ratings and for similar remaining maturities. The fair values of reverse mortgages are based on the net present value of the expected cash flows using a discount rate specific to the reverse mortgages portfolio. The fair value of nonperforming loans is based on recent external appraisals of the underlying collateral, if the loan is collateral dependent. Estimated cash flows, discounted using a rate commensurate with current rates and the risk associated with the estimated cash flows, are used if appraisals are not available. This technique does contemplate an exit price. Stock in the Federal Home Loan Bank (FHLB) of Pittsburgh The fair value of FHLB stock is assumed to be equal to its cost basis, since the stock is non-marketable but redeemable at its par value. Accrued interest receivable The carrying amounts of interest receivable approximate fair value. Other assets Other assets include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, and risk participation agreements (see discussion in “Fair Value of Financial Assets and Liabilities” section above). Deposits The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, money market and interest-bearing demand deposits, is assumed to be equal to the amount payable on demand. The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using rates currently offered for deposits with comparable remaining maturities. Borrowed funds Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt. Off-balance sheet instruments The fair value of off-balance sheet instruments, including swap guarantees of $7.7 million at September 30, 2023 and $10.4 million at December 31, 2022, respectively, and standby letters of credit, approximates the recorded net deferred fee amounts. Because letters of credit are generally not assignable by either the Company or the borrower, they only have value to the Company and the borrower. In determining the fair value of the swap guarantees, the Company assesses the underlying credit risk exposure for each borrower in a paying position to the third-party financial institution. Accrued interest payable The carrying amounts of interest payable approximate fair value. Other liabilities Other liabilities include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, foreign exchange forward contracts, risk participation agreements, and derivative related to the sale of certain Visa Class B common shares (see discussion in “Fair Value of Financial Assets and Liabilities” section above).
