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 2021 Annual Report on Form 10-K. Those significant accounting policies remain unchanged at March 31, 2022. RECENT ACCOUNTING PRONOUNCEMENTS The following accounting pronouncement was adopted by the Company during the three months ended March 31, 2022, but is not expected to have a material impact on the unaudited Consolidated Financial Statements: • ASU No. 2021-05, Leases (Topic 842), Lessors – Certain Leases with Variable Lease Payments There were no other applicable material accounting pronouncements adopted by the Company since December 31, 2021. Accounting guidance pending adoption at March 31, 2022 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 (TDRs) 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 guidance is effective for annual periods beginning after December 15, 2022. Early adoption is permitted. Adoption is required on a prospective basis, except for the transition method related to the recognition and measurement of TDRs where the entity as to apply on a modified-retrospective basis. The Company is currently evaluating the impact upon adoption and will apply the guidance after completion of its assessment.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	3. BUSINESS COMBINATIONS Bryn Mawr Bank Corporation. On January 1, 2022, WSFS closed its acquisition of BMBC and acquired 100% of the outstanding common stock of BMBC. In accordance with the terms of the merger agreement, dated March 9, 2021, by and between WSFS and BMBC, each share of BMBC common stock was exchanged for 0.90 shares of WSFS common stock (with cash paid in lieu of fractional shares). The total value of consideration paid was $908.0 million based on 19,903,230 shares of BMBC common stock outstanding as of December 31, 2021, the vesting of 226,643 BMBC restricted stock awards, and the closing price per share of WSFS common stock of $50.12 on December 31, 2021. Results of the combined Company’s operations are included in the unaudited Consolidated Financial Statements since the date of the acquisition. BMBC was the holding company for The Bryn Mawr Trust Company (Bryn Mawr Bank), a Pennsylvania chartered bank and wholly-owned subsidiary. BMBC and Bryn Mawr Bank were headquartered in Bryn Mawr, Pennsylvania, a western suburb of Philadelphia, and served primarily the Greater Philadelphia region. BMBC and its direct and indirect subsidiaries was a locally managed, premier financial services company providing retail and commercial banking; trust administration and wealth management; and insurance and risk management solutions. WSFS believes that following the BMBC Merger it will be the only bank in the Greater Philadelphia and Delaware region with distinct market-share advantages, including market knowledge, local decision-making, a full-service product suite and a balance sheet to compete with larger regional and national banks. The BMBC Merger also allows WSFS to accelerate our long-term strategic objectives, including scale to continue to invest in our delivery and talent transformations. The acquisition of BMBC was accounted for as a business combination using the acquisition method of accounting and, accordingly, the assets acquired, liabilities assumed and consideration transferred were recorded at their estimated fair values as of the acquisition date. The excess of consideration transferred over the fair value of net assets acquired was recorded as goodwill, which is not amortizable nor deductible for tax purposes. The Company allocated goodwill to its WSFS Bank segment and Wealth Management segment. During the three months ended March 31, 2022, there were no remeasurement period adjustments made to the fair values of assets acquired and liabilities assumed. The following table summarizes the consideration transferred and the fair values of identifiable assets acquired and liabilities assumed: (Dollars in thousands) Consideration Transferred: Fair Value Common shares issued (18,116,848) $ 908,016 Cash paid to BMBC stock and option holders 16 Value of consideration 908,032 Assets acquired: Cash and due from banks 573,761 Investment securities 500,400 Loans and leases 3,456,748 Premises and equipment 44,842 Deferred income taxes 8,433 Bank owned life insurance 67,525 Intangible assets 74,565 Other assets 145,491 Total assets 4,871,765 Liabilities assumed: Deposits 4,110,271 Other borrowings 145,512 Other liabilities 123,200 Noncontrolling interest (913) Total liabilities and noncontrolling interest 4,378,070 Net assets acquired: 493,695 Goodwill resulting from acquisition of BMBC $ 414,337 While the valuation of acquired assets and liabilities is substantially completed, fair value estimates related to the assets and liabilities from BMBC are subject to adjustment for up to one year after the closing date of the acquisition as additional information becomes available. Valuations subject to adjustment include, but are not limited to, Wealth Management intangibles, loans, and deferred income taxes as management continues to review the estimated fair values and evaluate the assumed tax position. When the valuation is final, any changes to the preliminary valuation of acquired assets and liabilities could result in adjustments to identified intangibles and goodwill. The fair values of assets acquired and liabilities assumed is expected to be finalized during the remeasurement period, which ends one year from the closing date, or January 1, 2023. The amount of goodwill recorded reflects the increased market share and related synergies that are expected to result from the acquisition, and represents the excess purchase price over the estimated fair value of the net assets acquired from BMBC. The following is a description of the valuation methodologies used to estimate the fair values of major categories of assets acquired and liabilities assumed. In many cases, the fair values of the assets acquired and liabilities assumed were determined by estimating the cash flows expected to result from those assets and liabilities and applying the appropriate market discount rates. Cash and due from banks : The estimated fair values of cash and due from banks approximate their stated value. Investment Securities : The acquired investment portfolio had a fair value of $500.4 million, primarily consisting of short-term U.S. Treasury bills that matured subsequent to closing on January 6, 2022. The estimated fair value approximated the stated value at maturity. Loans and Leases : The Company recorded $3.5 billion of acquired loans, which were initially recorded at their fair values as of the acquisition date. Fair value for loans was based on a discounted cash flow methodology that considered credit loss and prepayment expectations, market interest rates and other market factors, such as liquidity, from the perspective of a market participant. Loan cash flows were generated on an individual loan basis. The PD, LGD, exposure at default and prepayment assumptions are the key factors driving credit losses which are embedded into the estimated cash flows. The table below presents information with respect to the fair value and unpaid principal balance of acquired loans and leases at the acquisition date. January 1, 2022 (Dollars in thousands) Book Balance Fair Value Commercial and industrial $ 613,197 $ 586,643 Owner-occupied commercial 513,267 503,182 Commercial mortgages 1,564,234 1,549,515 Construction 209,928 208,288 Commercial small business leases 125,770 119,119 Residential 310,092 315,454 Consumer 178,247 174,547 Total acquired loans and leases $ 3,514,735 $ 3,456,748 The table below presents the carrying amount of loans for which, at the date of acquisition, there was evidence of more than insignificant deterioration of credit quality since origination: (Dollars in thousands) January 1, 2022 Book balance of loans at acquisition $ 235,791 Allowance for credit losses at acquisition (26,103) Non-credit related discount (1,421) Total purchase credit deteriorated (PCD) loans acquired $ 208,267 The BMBC Merger resulted in the addition of $49.6 million in allowance for credit losses, including the $26.1 million identified in the table above for PCD loans, and $23.5 million for non-PCD loans recorded through the provision for credit losses at the date of acquisition. Deferred Income Taxes : The Company recorded a deferred income tax asset (DTA) of $8.4 million related to tax attributes of BMBC along with the effects of fair value adjustments resulting from acquisition accounting for the combination. The DTA’s recorded were based on the expected federal and state tax benefits of when the acquired tax attributes and purchase accounting adjustments will reverse. In recording the DTA, consideration was given to potential limitations on the realizability of such acquired tax attributes. There was no material change to the valuation allowance as a result of the BMBC Merger. Trust preferred borrowings and subordinated debt : The fair value of trust preferred borrowings and subordinated debt were determined by present valuing the expected cash flows using current market rates for similar instruments. A fair value discount of $2.5 million was recognized for the trust preferred borrowings and will be recognized as an increase to interest expense over the remaining life of the borrowings. A fair value premium of $0.7 million was recognized for the subordinated debt and will be recognized as a decrease to interest expense over the remaining life of the debt. Intangible Assets : The Company recorded $10.9 million of core deposit intangible (CDI) which is being amortized over ten years using a straight-line amortization methodology. The fair value of the core deposit intangible was determined using the cost savings approach. The cost savings approach is defined as the difference between cost of funds on deposits and the cost of an equal amount of funds from an alternative source. The CDI fair value was determined by projecting net cash flow benefits, including assumptions related to customer attrition, discount rates, deposit interest rates, and alternative costs of funds. Certificates of deposit accounts were valued by segregating the portfolio into pools based on remaining maturity and comparing the contractual cost of the portfolio to an identical portfolio bearing current market rates. The valuation adjustment will be accreted or amortized to interest expense over the remaining maturities of the respective pools. WSFS recorded $60.4 million of Wealth Management intangible assets that consisted of $57.1 million for customer relationships in our wealth management, trust and insurances lines of business, $2.8 million for the Bryn Mawr Trust tradename, and $0.5 million in non-compete agreements. Fair value for these Wealth Management intangible assets was based on a discounted cash flow methodology projecting net cash flow benefits, including assumptions related to customer attrition, discount rates, income projections and applicable growth rate assumptions. Corporate development expenses and Restructuring expenses For acquisitions, the Company develops comprehensive integration plans under which it has incurred direct costs, which are expensed as incurred. These direct costs include costs are primarily related to: (i) terminated contracts, (ii) consolidated facilities (including lease termination expenses), (iii) severance, (iv) marketing, and (v) professional and legal fees. Costs related to the acquisition and restructuring are included in the Corporate development expense and Restructuring expense line items, respectively, on the unaudited Consolidated Statements of Income. The following table details the costs identified and classified as corporate development and restructuring expenses, which are primarily related to the BMBC Merger: Three Months Ended March 31, (dollars in thousands) 2022 Salaries, benefits and other compensation $ 10,043 Occupancy expense 10,239 Equipment expense 16,586 Professional fees 8,776 Data processing and operations expenses 29 Marketing expense 1,043 Other operating expense 4,836 Total corporate development and restructuring expenses $ 51,552 During the second quarter of 2021, WSFS announced a retail banking office optimization plan that included the planned consolidation of Bryn Mawr Trust and WSFS Bank banking offices. Most of the consolidations and rebranding of the banking offices were completed during the first quarter of 2022, which included 22 Bryn Mawr Trust and 12 WSFS Bank banking offices. Costs related to this plan are included in the Corporate development expense line item on the unaudited Consolidated Statements of Income. In addition, the Company had $11.8 million of premises and equipment as held-for-sale as of March 31, 2022, which is included in the Other assets line item on the unaudited Consolidated Statement of Financial Condition. Pro Forma Income Statement (unaudited) The following pro forma income statement for the three months ended March 31, 2021 presents the pro forma results of operations of the combined institution (BMBC and the Corporation) as if the BMBC Merger occurred on January 1, 2021. The pro forma income statement adjustments are limited to the effects of fair value mark amortization and accretion and intangible asset amortization. No cost savings or additional merger expenses have been included in the pro forma results of operations. Three Months Ended March 31, (dollars in thousands, except share and per share data) 2021 Net interest income $ 149,613 Provision for loan and lease losses (1,634) Net interest income after provision for loan and lease losses 151,247 Total noninterest income 67,663 Total noninterest expenses 133,856 Income before income taxes 85,054 Income tax expense 20,454 Net income $ 64,600 Per share data: Weighted-average basic shares outstanding 65,426,291 Dilutive shares 411,480 Adjusted weighted-average diluted shares 65,837,770 Basic earnings per common share $ 0.99 Diluted earnings per common share $ 0.98 Due to the various conversions of BMBC systems since the date of acquisition, as well as other streamlining and continuing integration of BMBC's operating activities into those of the Company, reporting for revenue and net income of the former BMBC operations for the period subsequent to the acquisition is impracticable.

NONINTEREST INCOME	4. NONINTEREST INCOME Credit/debit card and ATM income The following table presents the components of credit/debit card and ATM income: Three Months Ended March 31, (Dollars in thousands) 2022 2021 Bailment fees $ 2,785 $ 3,059 Interchange fees 4,099 3,055 Other card and ATM fees 797 691 Total credit/debit card and ATM income $ 7,681 $ 6,805 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 March 31, (Dollars in thousands) 2022 2021 Trust fees $ 19,090 $ 9,764 Wealth management and advisory fees 11,091 4,489 Total investment management and fiduciary income $ 30,181 $ 14,253 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 Cypress, West Capital, Powdermill ®, WSFS Wealth ® Investments and legacy Bryn Mawr Trust Wealth Management (excluding The Bryn Mawr Trust Company of Delaware). 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 quarterly and annual billing for the services. Deposit service charges The following table presents the components of deposit service charges: Three Months Ended March 31, (Dollars in thousands) 2022 2021 Service fees $ 3,884 $ 3,422 Return and overdraft fees 1,775 1,578 Other deposit service fees 166 460 Total deposit service charges $ 5,825 $ 5,460 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, cash 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 March 31, (Dollars in thousands) 2022 2021 Managed service fees $ 3,838 $ 3,609 Currency preparation 871 948 ATM loss protection 608 622 Capital market revenue 1,508 — Insurance commissions 1,295 — Miscellaneous products and services 4,433 3,506 Total other income $ 12,553 $ 8,685 Other income consists of managed service fees, which are primarily courier fees related to cash 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. Through its subsidiary BMT Insurance Advisors, the Bank earns 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. Arrangements with multiple performance obligations 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.

As of March 31, 2022, the Company’s available for sale investment securities consisted of 1,089 securities, 934 of which were in an unrealized loss position. As of March 31, 2022, substantially all of the Corporation’s available for sale investment securities were mortgage-backed securities or collateral mortgage obligations which were issued or guaranteed by U.S. government-sponsored entities and agencies. As of March 31, 2022 and December 31, 2021, there were no holdings of securities of any one issuer, other than the U.S. government and its agencies, in an amount greater than 10% of shareholders’ equity. The scheduled maturities of held-to-maturity debt securities at March 31, 2022 and December 31, 2021 are presented in the table below: Held-to-Maturity Amortized Fair (Dollars in thousands) Cost Value March 31, 2022 (1) Within one year $ 1,031 $ 1,031 After one year but within five years 2,674 2,689 After five years but within ten years 38,696 39,217 After ten years 42,501 42,817 $ 84,902 $ 85,754 December 31, 2021 (1) Within one year $ 232 $ 234 After one year but within five years 2,675 2,736 After five years but within ten years 44,137 45,404 After ten years 43,602 45,757 $ 90,646 $ 94,131 (1) Actual maturities could differ from contractual maturities. MBS may have expected maturities that differ from their contractual maturities. These differences arise because issuers may have the right to call securities and borrowers may have the right to prepay obligations with or without prepayment penalty. The estimated weighted average duration of MBS was 5.5 years at March 31, 2022. The held-to-maturity debt securities are not collateral-dependent securities as these are general obligation bonds issued by cities, states, counties, or other local and foreign governments. Investment securities with fair market values aggregating $2.7 billion and $2.2 billion were pledged as collateral for retail customer repurchase agreements, municipal deposits, and other obligations as of March 31, 2022 and December 31, 2021, respectively. During the three months ended March 31, 2022, the Company had no sales of debt securities categorized as available-for-sale, resulting in no realized gains and no realized losses. During the three months ended March 31, 2021, the Company sold $9.3 million of debt securities categorized as available-for-sale resulting in $0.3 million of realized gains and no realized losses.

Total unrealized losses on these securities were $411.3 million at March 31, 2022. The Company does not have the intent to sell, nor is it more likely than not it will be required to sell these securities before it is able to recover the amortized cost basis. The unrealized losses are the result of changes in market interest rates subsequent to purchase, not credit loss, as these are highly rated agency securities with no expected credit loss, in the event of a default. As a result, there is no allowance for credit losses recorded for available-for-sale debt securities as of March 31, 2022. At March 31, 2022 and December 31, 2021, held-to-maturity debt securities had an amortized cost basis of $84.9 million and $90.6 million, respectively. The held-to-maturity debt security portfolio primarily consists of highly rated municipal bonds. The Company monitors credit quality of its debt securities through credit ratings. The following table summarizes the amortized cost of debt securities held-to-maturity as of March 31, 2022, aggregated by credit quality indicator: (Dollars in thousands) State and political subdivisions Foreign bonds A+ rated or higher $ 84,102 $ 800 Not rated — — Ending balance $ 84,102 $ 800 The following table summarizes the amortized cost of debt securities held-to-maturity as of December 31, 2021, aggregated by credit quality indicator: (Dollars in thousands) State and political subdivisions Foreign bonds A+ rated or higher $ 90,146 $ 500 Not rated — — Ending balance $ 90,146 $ 500 The Company reviewed its held-to-maturity debt securities by major security type for potential credit losses.

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. The following tables provide an analysis of loans by portfolio segment based on the credit quality indicators used to determine the allowance for credit losses as of March 31, 2022.

Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES OF FINANCIAL ASSETS AND LIABILITIES	14. 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 March 31, 2022 and December 31, 2021 by level in the valuation hierarchy (as described above): March 31, 2022 (Dollars in thousands) Quoted Significant Significant Total Fair Assets measured at fair value on a recurring basis: Available-for-sale securities: CMO $ — $ 563,090 $ — $ 563,090 FNMA MBS — 4,586,978 — 4,586,978 FHLMC MBS — 126,406 — 126,406 GNMA MBS — 16,059 — 16,059 GSE agency notes — 203,396 — 203,396 Other assets — 72,252 209 72,461 Total assets measured at fair value on a recurring basis $ — $ 5,568,181 $ 209 $ 5,568,390 Liabilities measured at fair value on a recurring basis: Other liabilities $ — $ 70,516 $ 18,632 $ 89,148 Assets measured at fair value on a nonrecurring basis: Other investments $ — $ — $ 13,651 $ 13,651 Other real estate owned — — 1,818 1,818 Loans held for sale — 70,617 — 70,617 Total assets measured at fair value on a nonrecurring basis $ — $ 70,617 $ 15,469 $ 86,086 December 31, 2021 (Dollars in thousands) Quoted Significant Significant Total Fair Assets measured at fair value on a recurring basis: Available-for-sale securities: CMO $ — $ 575,766 $ — $ 575,766 FNMA MBS — 4,245,684 — 4,245,684 FHLMC MBS — 145,528 — 145,528 GNMA MBS — 17,936 — 17,936 GSE agency notes — 220,397 — 220,397 Other assets — 5,153 — 5,153 Total assets measured at fair value on a recurring basis $ — $ 5,210,464 $ — $ 5,210,464 Liabilities measured at fair value on a recurring basis: Other liabilities $ — $ 3,039 $ 20,252 $ 23,291 Assets measured at fair value on a nonrecurring basis Other investments $ — $ — $ 10,518 $ 10,518 Other real estate owned — — 2,320 2,320 Loans held for sale — 113,349 — 113,349 Total assets measured at fair value on a nonrecurring basis $ — $ 113,349 $ 12,838 $ 126,187 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 with and without readily determinable fair values and equity method investments, which are categorized as Level 3. The Company's equity investments with a readily determinable fair value are held at fair value. 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 with and 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 $12.5 million at March 31, 2022 and $13.1 million at December 31, 2021, 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 Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	15. 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 Corporation does not use derivative financial instruments for trading purposes. Fair Values of Derivative Instruments The table below presents the fair value of derivative financial instruments as well as their location on the unaudited Consolidated Statements of Financial Condition as of March 31, 2022. Fair Values of Derivative Instruments (Dollars in thousands) Notional Balance Sheet Location Derivatives Derivatives not designated as hedging instruments: Interest rate products $ 1,428,507 Other assets $ 69,824 Interest rate products 1,428,507 Other liabilities (69,874) Interest rate lock commitments with customers 59,199 Other assets 833 Interest rate lock commitments with customers 48,435 Other liabilities (573) Forward sale commitments 92,690 Other assets 1,595 Forward sale commitments 12,911 Other liabilities (39) FX forwards 803 Other liabilities (30) Risk participation agreements sold 53,175 Other liabilities (7) Risk participation agreements purchased 66,872 Other assets 209 Financial derivatives related to 113,177 Other liabilities (18,625) Total derivatives $ 3,304,276 $ (16,687) The table below presents the fair value of derivative financial instruments as well as their location on the Consolidated Statements of Financial Condition as of December 31, 2021. Fair Values of Derivative Instruments (Dollars in thousands) Notional Balance Sheet Location Derivatives Derivatives not designated as hedging instruments: Interest rate products $ 54,834 Other assets $ 2,625 Interest rate products 54,834 Other liabilities (2,847) Risk participation agreements 4,214 Other liabilities (3) Interest rate lock commitments with customers 102,264 Other assets 1,991 Interest rate lock commitments with customers 12,813 Other liabilities (73) Forward sale commitments 63,664 Other assets 537 Forward sale commitments 67,032 Other liabilities (116) Financial derivatives related to 113,177 Other liabilities (20,252) Total derivatives $ 472,832 $ (18,138) Derivatives Designated as Hedging Instruments: Cash Flow Hedges of Interest Rate Risk In 2020, the Company terminated its three interest rate derivatives 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 continues to be probable, the $1.3 million net gain will be recognized into earnings on a straight-line basis over each derivative's original contract term. During the three months ended March 31, 2022, $0.1 million was reclassified into interest income. During the next twelve months, the Company estimates that an additional $0.2 million will be reclassified as an increase to interest income. Derivatives Not Designated as Hedging Instruments: Swap Guarantees The Company entered into agreements with five unrelated financial institutions whereby those financial institutions 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, those financial institutions have 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 March 31, 2022 and December 31, 2021, there were 259 and 261 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 $1.1 billion and $1.1 billion at March 31, 2022 and December 31, 2021, respectively. At March 31, 2022, the swap transactions remaining maturities ranged from under 1 year to 14 years. At March 31, 2022, 82 of these customer swaps were in a paying position to third parties for $6.6 million, with our swap guarantees having a fair value of $12.5 million. At December 31, 2021, 193 of these customer swaps were in a paying position to third parties for $35.8 million, with the Company's swap guarantees having a fair value of $13.1 million. However, for both periods, none of the Company's customers were in default of the swap agreements. 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 FASB 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 FASB ASC 820. As of March 31, 2022, 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. The table below presents the effect of the derivative financial instruments on the unaudited Consolidated Statements of Income for the three months ended March 31, 2022 and March 31, 2021. Amount of (Loss) or Gain Recognized in Income Location of Gain or (Loss) Recognized in Income (Dollars in thousands) Three Months Ended March 31, Derivatives not designated as hedging instruments 2022 2021 Interest rate lock commitments with customers $ (1,227) $ (3,264) Mortgage banking activities, net Forward sale commitments 3,137 6,123 Mortgage banking activities, net Total $ 1,910 $ 2,859 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 FASB 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 FASB ASC 820. As of March 31, 2022, 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.” 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 $6.0 million in securities and $7.2 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 March 31, 2022, it could have been required to settle its obligations under the agreements at the termination value.

COMMITMENTS AND CONTINGENCIES	17. 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 on a more limited basis, to GSEs such as FHLMC, FNMA, and 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 in 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, Derivatives and Hedging (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 were two repurchases for $0.8 million during the three months ended March 31, 2022 and no repurchases during the same period in 2021. Unfunded Lending Commitments At March 31, 2022 and December 31, 2021, the allowance for credit losses of unfunded lending commitments was $11.7 million and $7.4 million, respectively. A provision of $0.1 million was recognized during the three months ended March 31, 2022 compared to a provision for unfunded lending commitments of $0.6 million during the three months ended March 31, 2021.

LEGAL AND OTHER PROCEEDINGS	19. 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)	3 Months Ended
	Mar. 31, 2022
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), fair values of assets acquired and liabilities assumed in acquisitions accounted for as business combinations using the acquisition method of accounting, 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, 2022. 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, 2021 (the 2021 Annual Report on Form 10-K) that was filed with the SEC on March 1, 2022 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.
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS The following accounting pronouncement was adopted by the Company during the three months ended March 31, 2022, but is not expected to have a material impact on the unaudited Consolidated Financial Statements: • ASU No. 2021-05, Leases (Topic 842), Lessors – Certain Leases with Variable Lease Payments There were no other applicable material accounting pronouncements adopted by the Company since December 31, 2021. Accounting guidance pending adoption at March 31, 2022 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 (TDRs) 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 guidance is effective for annual periods beginning after December 15, 2022. Early adoption is permitted. Adoption is required on a prospective basis, except for the transition method related to the recognition and measurement of TDRs where the entity as to apply on a modified-retrospective basis. The Company is currently evaluating the impact upon adoption and will apply the guidance after completion of its assessment.
Fair Value Measurement	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 with and without readily determinable fair values and equity method investments, which are categorized as Level 3. The Company's equity investments with a readily determinable fair value are held at fair value. 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 with and 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 $12.5 million at March 31, 2022 and $13.1 million at December 31, 2021, 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).
