Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION General Our unaudited Consolidated Financial Statements include the accounts of WSFS Financial Corporation (the Company or WSFS), Wilmington Savings Fund Society, FSB (WSFS Bank or the Bank), WSFS Wealth Management, LLC (Powdermill), WSFS Capital Management, LLC (West Capital), Cypress Capital Management, LLC (Cypress), Christiana Trust Company of Delaware (Christiana Trust DE) and WSFS SPE Services, LLC. We also have one unconsolidated subsidiary, WSFS Capital Trust III. WSFS Bank has three wholly owned subsidiaries: Beneficial Equipment Finance Corporation (BEFC), WSFS Investment Group, Inc. (WSFS Wealth Investments), 1832 Holdings, Inc., and one majority-owned subsidiary, NewLane Finance Company (NewLane Finance). 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.). We provide residential and commercial real estate, commercial and consumer lending services, as well as retail deposit and cash management services. Our core banking business is commercial lending funded primarily by customer-generated deposits. In addition, we offer a variety of wealth management and trust services to personal and corporate customers. The Federal Deposit Insurance Corporation (FDIC) insures our customers’ deposits to their legal maximums. We serve our customers primarily from 116 offices located in Pennsylvania (54 ), Delaware ( 44) , New Jersey (16 ), Virginia (1) and Nevada (1), our ATM network, our website at www.wsfsbank.com and our mobile app. Information on our website is not incorporated by reference into this Quarterly Report on Form 10-Q. Our leasing business is conducted by NewLane Finance. During the third quarter of 2019, the leasing operations of NewLane Finance and BEFC were combined and all new leases are now originated at NewLane Finance. NewLane Finance originates small business leases and provides commercial financing to businesses nationwide, targeting various equipment categories including technology, software, office, medical, veterinary and other areas. Basis of Presentation In preparing the unaudited Consolidated Financial Statements, we are 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 as well as increased post-retirement benefits expense. Our 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, 2020. These unaudited, interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2019 (the 2019 Annual Report on Form 10-K) that was filed with the SEC on March 2, 2020 and is available at www.sec.gov or on our 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 our Consolidated Financial Statements are disclosed in our 2019 Annual Report on Form 10-K. Those significant accounting policies remain unchanged at March 31, 2020, except as described below: Loans Loans held for investment are recorded at amortized cost, net of allowance for credit losses. Amortized cost is the amount at which a financial asset is originated or acquired, adjusted for the amortization of premium and discount, net deferred fees or costs, collection of cash, and write-offs. Interest income on loans is recognized using the level yield method. Loan origination fees, commitment fees and direct loan origination costs are deferred and recognized over the life of the related loans using a level yield method over the period to maturity. Allowance for Credit Losses - Loans and Leases We establish our 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 management's current estimate of expected credit losses, including our portfolio mix and segmentation, modeling methodology, historical loss experience, relevant available information from internal and external sources relating to reasonable and supportable forecasts about future economic conditions, prepayment speeds, and qualitative adjustment factors. The Company's portfolio segments, established based on similar risk characteristics and loss behaviors, are: • Commercial and industrial, owner-occupied commercial, commercial mortgages, construction and commercial small business leases (collectively, commercial loans), and • Residential, equity secured lines and loans, installment loans, unsecured lines of credit and education loans (collectively, retail loans). Expected credit losses are estimated over the contractual term, adjusted for expected prepayments and recoveries. The contractual term excludes any extensions, renewals and modifications unless the Company has reasonable expectations at the reporting date that it will result in a TDR or they are not unconditionally cancellable. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. 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 retail loans, and each portfolio segment is further segmented by internally assessed risk ratings. Management uses a third-party economic forecast to modify the calculated historical loss rates of the portfolio segments. Our economic 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 we believe this to be reasonable and supportable in the current environment. The economic forecast and reversion periods will be evaluated periodically by management 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). 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 retail loans is calculated based solely on average net loss rates over the same look-back period. Our current look-back period is 37 quarters which allows us to ensure that 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 TDRs, are not included in the collective basis evaluation. When it is probable we 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 one of 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 is 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), 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 in our model can add to or subtract from quantitative reserves. Our 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 our loan ratings and allowance for credit losses and the Bank’s internal loan review department performs loan reviews. Accrued interest receivable on loans is excluded from the estimate of credit losses and is included in Accrued interest receivable on the Consolidated Statements of Financial Condition. For additional detail regarding the allowance for credit losses and the provision for credit losses, see Note 8. Past Due and Nonaccrual Loans Past due loans are defined as loans contractually past due 30 days or more as to principal or interest payments but which remain in accrual status because they 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 management, 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 management’s assessment of the ultimate collectability of principal and interest. Loans are returned to accrual status when we assess 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). Unless loans are well-secured and collection is imminent, for loans greater than 90 days past due 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 resulting in a concession to the borrower experiencing financial difficulty, is considered a troubled debt restructuring (TDR). Principal balances are generally not forgiven when a loan is modified as a TDR. Nonaccruing restructured loans remain in nonaccrual status until there has been a period of sustained repayment performance demonstrated, as noted above, and repayment is reasonably assured. For additional detail regarding past due and nonaccrual loans, see Note 8. Debt Securities Investments in debt securities are classified into one of the following three categories and accounted for as follows: • Securities purchased with the intent of selling them in the near future are classified as “trading” and reported at fair value, with unrealized gains and losses included in earnings. • Securities purchased with the positive intent and ability to hold to maturity are classified as “held-to-maturity” and reported at amortized cost. • Securities not classified as either trading or held-to-maturity are classified as “available-for-sale” and reported at fair value, with unrealized gains and losses excluded from earnings and reported, net of tax, as a separate component of stockholders’ equity in accumulated other comprehensive income (loss). Realized gains and losses on sales of investment and mortgage-backed securities (MBS) are determined using the specific identification method. All sales are made without recourse. Debt securities mostly include mortgage-backed securities (MBS), municipal bonds, and U.S. government and agency securities. Premiums and discounts on MBS collateralized by residential 1-4 family loans are recognized in interest income using a level yield method over the period to expected maturity. Premiums and discounts on all other securities are recognized on a straight line basis over the period to expected maturity, with the exception of premiums on callable debt securities, which are recognized over the period to the earliest call date. The fair value of debt securities is primarily obtained from third-party pricing services. Implicit in the valuation of MBS are estimated prepayments based on historical and current market conditions. A debt security is placed on nonaccrual status at the time any principal or interest payments are contractually past due 90 days or more. Interest accrued but not received for a security placed on nonaccrual status is reversed against interest income. Our investment portfolio is reviewed each quarter for indications of potential credit losses. Refer to the respective held-to-maturity and available-for-sale debt securities sections for management's discussion of the allowance for credit loss for each portfolio. Allowance for Credit Losses - Held-to-Maturity Debt Securities We follow Accounting Standards Codification (ASC) 326-20, Financial Instruments - Credit Loss - Measured at Amortized Cost, to measure expected credit losses on held-to-maturity debt securities on a collective basis by security investment grade. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The Company classifies the held-to-maturity debt securities into the following major security types: state and political subdivisions, and foreign bonds. These securities are highly rated with a history of no credit losses, and are assigned ratings based on the most recent data from ratings agencies depending on the availability of data for the security. Credit ratings of held-to-maturity debt securities, which are a significant input in calculating the expected credit loss, are reviewed on a quarterly basis. Accrued interest receivable on held-to-maturity debt securities is excluded from the estimate of credit losses and is included in Accrued interest receivable on the Consolidated Statements of Financial Condition. Allowance for Credit Losses - Available-for-Sale Debt Securities We follow ASC 326-30, Financial Instruments - Cre dit Loss - Available-for-Sale Debt Securities, which provides guidance related to the recognition of and expanded disclosure requirements for expected credit losses on available-for-sale debt securities. For available-for-sale debt securities in an unrealized loss position, the Company first evaluates whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either criteria is met, the security's amortized cost basis is reduced to fair value and recognized as a reduction to Noninterest income in the Consolidated Statements of Income. For debt securities available-for-sale which the Company does not intend to sell, or it is not likely the security would be required to be sold before recovery, we evaluate whether a decline in fair value has resulted from credit losses or other adverse factors, such as a change in the security's credit rating. In assessing whether a credit loss exists, the Company compares the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance is recorded, limited to the fair value of the security. Management performs this analysis on a quarterly basis to review the conditions and risks associated with the individual securities. Credit losses on an impaired security shall continue to be measured using the present value of expected future cash flows. Any impairment not recorded through an allowance for credit loss is included in other comprehensive income (loss), net of the tax effect. We are required to use our judgment in determining impairment in certain circumstances. For additional detail regarding debt securities, see Note 6. Unfunded Lending Commitments For unfunded lending commitments, the Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The estimate includes consideration of the probability of default and utilization rate at default to calculate expected credit losses on commitments expected to be funded over its estimated life of one year, based on historical losses, and qualitative adjustment factors. The allowance for credit losses for off-balance sheet exposures is included in Other liabilities on the Consolidated Statements of Financial Condition and the provision for credit losses for off-balance sheet exposure is included in Other operating expense on the Consolidated Statements of Income. For additional detail regarding the allowance for credit losses and the provision for credit losses, see Note 17. RECENT ACCOUNTING PRONOUNCEMENTS Accounting Guidance Adopted in 2020 ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) . ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with the current expected credit losses (CECL) methodology which requires management consideration and judgment of a broader range of information to determine credit loss estimates. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326 , clarifying that operating lease receivables are not within the scope of Topic 326. In December 2018, federal regulators issued a final rule related to regulatory capital and CECL (Regulatory Capital Rule: Implementation and Transition of the Current Expected Credit Losses Methodology for Allowances and Related Adjustments to the Regulatory Capital Rule and Conforming Amendments to Other Regulations) , intended to provide regulatory capital relief for entities transitioning to CECL. In May 2019, the FASB issued ASU No. 2019-05, Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief , providing entities the option to irrevocably elect the fair value option on eligible financial instruments, which excludes held-to-maturity debt securities. In November 2019, the FASB issued ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, clarifying guidance on expected recoveries for purchased credit deteriorated financial assets, accrued interest receivable and collateral maintenance provisions and providing transition relief for troubled debt restructurings. In March 2020, the FASB issued ASU No. 2020-03, Codification Improvements to Financial Instruments , clarifying the contractual term of a net investment in a lease and the requirement to establish an allowance for credit loss when an entity regains control of sold financial assets. While the CARES Act provides an option to defer implementation of the CECL methodology, the Company adopted this guidance on January 1, 2020, using the modified retrospective approach for financial assets recorded at amortized cost with the exception of purchase credit deteriorated (PCD) assets, which were previously classified as purchase credit impaired (PCI) accounted for under ASC 310-30, adopted using the prospective approach. The cumulative effect of the adoption resulted in a $30.4 million decrease to the beginning balance of retained earnings as of January 1, 2020. Results and disclosures for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. For further details on the impact of the adoption, accounting policies, elections, and practical expedients applied, see updated Significant Accounting Policies and CECL disclosures throughout the Notes to the Consolidated Financial Statements. The following table illustrates the impact of ASC 326 for our loans, leases, purchased financial assets, debt securities, other assets and unfunded lending commitments compared to the incurred loss approach, as disclosed prior to our adoption on January 1, 2020.

ASU No. 2018-13, Fair Value Measurement Disclosure Framework: In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement Disclosure Framework , which amends ASC 820 - Fair Value Measurement . The new guidance modifies, adds and removes certain disclosures aimed to improve the overall usefulness of the disclosure requirements for fair value measurements. The guidance is effective in annual and interim periods in fiscal years beginning after December 15, 2019. Early adoption is permitted. Adoption is required on either a prospective or retrospective basis, depending on the amendment. The Company adopted this standard on January 1, 2020. See Note 14 for changes to financial statement disclosures resulting from our adoption of this standard. ASU No. 2018-14, Compensation-Retirement Benefits - Defined Benefit Plans-General (Topic 715): In August 2018, the FASB issued ASU No. 2018-14, Compensation-Retirement Benefits - Defined Benefit Plans-General (Topic 715) which applies to all employers that provide defined benefit pension or other postretirement benefit plans for their employees. The new guidance modifies, adds and removes certain disclosures aimed to improve the overall usefulness of the disclosure requirements to financial statement users. The guidance is effective for annual periods beginning after December 15, 2020. Early adoption is permitted. Use of the retrospective method is required. The Company early adopted this standard on January 1, 2020. See Note 12 for changes to financial statement disclosures resulting from our adoption of this standard. ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Topic 350) : In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Topic 350) . The new guidance provides clarity on capitalizing and expensing implementation costs for cloud computing arrangements in a service contract. If an implementation cost is capitalized, the cost should be recognized over the noncancellable term and periodically assessed for impairment. The guidance is effective in annual and interim periods in fiscal years beginning after December 15, 2019. Early adoption is permitted. Adoption can be applied retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company adopted this standard on January 1, 2020, on a prospective basis with no impact to the Consolidated Financial Statements at the time of adoption. ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments: In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The new guidance amends ASU 2016-13 to address topics related to accrued interest receivables, recoveries, disclosures, and provides certain other clarifications. The new guidance also amends ASU 2017-12 to provide clarification on certain hedge accounting topics and transition requirements. Lastly, the new guidance amends ASU 2016-01, Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities , to add clarifying guidance when using the measurement alternative under ASC 820, among certain other clarifications. The guidance is effective for annual periods beginning after December 15, 2019. Early adoption is permitted. Adoption is required on a prospective, modified-retrospective or retrospective basis, depending on the amendment. The Company included the amendments related to ASU 2016-13 as part of our CECL guidance implementation and adoption at January 1, 2020. The Company adopted other amendments within this guidance on January 1, 2020 with no impact to the Consolidated Financial Statements at the time of adoption.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	3. BUSINESS COMBINATIONS Beneficial Bancorp, Inc. On March 1, 2019, the Company acquired Beneficial. Subject to the terms and conditions of the merger agreement, the Beneficial stockholders received 0.3013 shares of WSFS common stock and $2.93 in cash for each share of Beneficial common stock. Based on the February 28, 2019 closing share price of $43.28, the value of the stock consideration was $950.0 million and cash consideration was $228.2 million, for total transaction value of $1.2 billion. Results of the combined Company’s operations are included in the Consolidated Financial Statements since the date of the acquisition. Beneficial conducted its primary business operations through its wholly owned subsidiary, Beneficial Bank, which was merged into WSFS Bank. At closing, Beneficial had 74 branches and offices in southeastern Pennsylvania and southern New Jersey. WSFS acquired Beneficial to expand the scale and efficiency of its operations in the Philadelphia, southeastern Pennsylvania and New Jersey markets, and to create opportunities to generate additional revenue by providing its full suite of banking, mortgage banking, wealth management and insurance services to the legacy Beneficial markets. The acquisition of Beneficial 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 the total balance of goodwill to its WSFS Bank segment. The remeasurement period expired on February 29, 2020, one The following table summarizes the consideration transferred and the fair values of identifiable assets acquired and liabilities assumed, which are considered final: (Dollars in thousands) Consideration Transferred: Fair Value Common shares issued (21,816,355) $ 949,968 Cash paid to Beneficial stock and option holders 228,239 Value of consideration 1,178,207 Assets acquired: Cash and due from banks 304,311 Investment securities 619,834 Loans and leases, net 3,711,246 Premises and equipment 69,873 Deferred income taxes 18,463 Bank owned life insurance 82,510 Core deposit intangible 85,053 Servicing rights intangible 2,466 Other assets 135,890 Total assets 5,029,646 Liabilities assumed: Deposits 4,056,506 Other liabilities 101,754 Total liabilities 4,158,260 Net assets acquired: 871,386 Goodwill resulting from acquisition of Beneficial $ 306,821 The following table details the changes to goodwill recorded subsequent to acquisition: (Dollars in thousands) Fair Value Goodwill resulting from the acquisition of Beneficial reported as of March 31, 2019 $ 309,486 Effects of adjustments to: Cash and due from banks 246 Investment securities (3,131) Loans 911 Premises and equipment (741) Deferred income taxes 1,007 Other assets (416) Deposits 790 Other liabilities (1,331) Final goodwill resulting from the acquisition of Beneficial as of February 29, 2020 $ 306,821 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. WSFS recorded $3.7 billion of acquired loans, which were initially recorded at their fair values as of the acquisition date. The acquired investment portfolio had a fair value of $619.8 million, of which $578.8 million of investment securities were sold subsequent to closing. The proceeds received for the investments sold approximated their fair values as of the acquisition date. The fair value of the retained investment portfolio was determined by taking into account market prices obtained from independent valuation source(s). See Note 14 for additional information. The Company recorded a deferred income tax asset (DTA) of $18.5 million related to tax attributes of Beneficial along with the effects of fair value adjustments resulting from acquisition accounting for the combination. WSFS recorded $85.1 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. As a result of the merger, the Company developed a comprehensive integration plan under which we have incurred direct costs, which were expensed as incurred. These direct costs include costs 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 Consolidated Statements of Income. During the fourth quarter of 2018, WSFS announced a retail banking office optimization plan that included the consolidation of fourteen Beneficial and eleven WSFS Bank banking offices. Most of the consolidations and rebranding of the remaining Beneficial banking offices were completed during the conversion, which occurred during the third quarter of 2019. Costs related to this plan are included in the Corporate development expense

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) 2020 2019 Bailment fees $ 5,081 $ 6,900 Interchange fees 5,616 4,387 Other card and ATM fees 662 228 Total credit/debit card and ATM income $ 11,359 $ 11,515 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 our customers. Bailment arrangements are legal relationships in which property is delivered to another party without a transfer of ownership. The party receiving the property (the bailee) has possession and control of the property and is obligated to take reasonable care of the property. 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) 2020 2019 Trust fees $ 6,954 $ 6,567 Wealth management and advisory fees 4,008 3,580 Total investment management and fiduciary income $ 10,962 $ 10,147 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 and trustee services on structured finance transactions; indenture trustee, administrative agent and collateral agent services to institutions and corporations; commercial domicile and independent director services; and investment and trustee services to families and individuals across the U.S. Most fees are flat fees, except for a portion of personal and corporate trustee fees where we earn a percentage on the assets under management. 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 Client Management, WSFS Wealth Investments and WSFS Institutional Services. 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) 2020 2019 Service fees $ 3,211 $ 2,716 Return and overdraft fees 2,332 1,848 Other deposit service fees 104 182 Total deposit service charges $ 5,647 $ 4,746 Deposit service charges includes revenue earned from our core deposit products, certificates of deposit, and brokered deposits. We generate 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) 2020 2019 Managed service fees $ 4,031 $ 2,943 Currency preparation 840 739 ATM insurance 647 627 Miscellaneous products and services 1,435 3,398 Total other income $ 6,953 $ 7,707 Other income consists of managed service fees, which are primarily courier fees related to cash management, currency preparation, ATM insurance 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. Arrangements with multiple performance obligations Our contracts with customers may include multiple performance obligations. For such arrangements, we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine standalone selling prices based on the prices charged to customers. Practical expedients and exemptions We do 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 we recognize revenue at the amount to which we have the right to invoice for services performed.

Mortgage-backed securities (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 2.2 years at March 31, 2020. 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 $1.3 billion and $1.1 billion were pledged as collateral for retail customer repurchase agreements, municipal deposits, and other obligations as of March 31, 2020 and December 31, 2019, respectively. During the three months ended March 31, 2020, we sold $30.6 million of debt securities categorized as available-for-sale resulting in $0.7 million realized gains and no realized losses. During the three months ended March 31, 2019, we sold $583.9 million of debt securities categorized as available-for-sale, of which $578.8 million was related to the acquisition of Beneficial. (see Note 3 for further information about the acquisition). The remaining $5.1 million resulted in realized gains of less than $0.1 million and no realized losses.

At March 31, 2020, we owned available-for-sale debt securities totaling $9.3 million for which the amortized cost basis exceeded fair value. Total unrealized losses on these securities were $0.1 million at March 31, 2020. We do not have the intent to sell, nor is it more likely than not we will be required to sell these securities before we are 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, 2020. At March 31, 2020, we owned held-to-maturity debt securities with an amortized cost basis of $134.1 million. Our 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.

Interest income of $0.2 million was recognized on impaired loans during the three months ended March 31, 2019. As of March 31, 2020, there were 30 residential loans and 24 commercial loans in the process of foreclosure. The total outstanding balance on these loans was $2.7 million and $5.9 million, respectively.

The total outstanding balance on these loans was $3.2 million and $9.5 million, respectively. Credit Quality Indicators Below is a description of each of our 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. 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 . 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.

GOODWILL AND INTANGIBLE ASSETS	10. 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 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 our review of the overall business to ensure no events or circumstances have occurred that would impact our goodwill evaluation. During the three months ended March 31, 2020, management included considerations of the current economic environment caused by COVID-19 in our evaluation, and determined based on the totality of our qualitative assessment that it is not more likely than not that the carrying value of goodwill is impaired. No goodwill impairment exists as of the three months ended March 31, 2020.

ASSOCIATE BENEFIT PLANS	12. ASSOCIATE BENEFIT PLANS Postretirement Medical Benefits We share certain costs of providing health and life insurance benefits to eligible retired Associates (employees) and their eligible dependents. Previously, all Associates were eligible for these benefits if they reached normal retirement age while working for us. Effective March 31, 2014, we changed the eligibility of this plan to include only those Associates who have achieved ten years of service with us as of March 31, 2014. As of December 31, 2014, we began to use the mortality table issued by the Office of the Actuary of the U.S. Bureau of Census in our calculation. We account for our obligations under the provisions of ASC 715, Compensation - Retirement Benefits (ASC 715). ASC 715 requires that we recognize the costs of these benefits over an Associate’s active working career. Amortization of unrecognized net gains or losses resulting from experience different from that assumed and from changes in assumptions is included as a component of net periodic benefit cost over the remaining service period of active employees to the extent that such gains and losses exceed 10% of the accumulated postretirement benefit obligation, as of the beginning of the year. We recognize our service cost in Salaries, benefits and other compensation and the other components of net periodic benefit cost in Other operating expenses in our unaudited Consolidated Statements of Income. The following table presents the components of net periodic benefit cost related to our postretirement medical benefits plan. Three months ended March 31, (Dollars in thousands) 2020 2019 Service cost $ 15 $ 13 Interest cost 17 19 Prior service cost amortization (19) (19) Net gain recognition (9) (15) Net periodic cost (benefit) $ 4 $ (2) Alliance Associate Pension Plan During the fourth quarter of 2015, we completed the acquisition of Alliance.

During the first quarter of 2020, the Company received IRS and PBGC approval, and has begun the next steps to complete the pension plan termination. Beneficial Associate Pension and other postretirement benefits plans On March 1, 2019, we closed our acquisition of Beneficial. At the time of the acquisition, we assumed the pension plan covering certain eligible Beneficial Associates. The plan was frozen in 2008.

ASC 740 requires the recording of deferred income taxes that reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. We exercise significant judgment in the evaluation of the amount and timing of the recognition of the resulting tax assets and liabilities. The judgments and estimates required for the evaluation are updated based on changes in business factors and tax laws. If actual results differ from the assumptions and other considerations used in estimating the amount and timing of tax recognized, there can be no assurance that additional expenses will not be required in future periods. ASC 740 prescribes a minimum probability threshold that a tax position must meet before a financial statement benefit is recognized. We recognize, when applicable, interest and penalties related to unrecognized tax benefits in the provision for income taxes in the financial statements. Assessment of uncertain tax positions under ASC 740 requires careful consideration of the technical merits of a position based on our analysis of tax regulations and interpretations. There were no unrecognized tax benefits as of March 31, 2020. We record interest and penalties on potential income tax deficiencies as income tax expense. Our federal and state tax returns for the 2016 through 2019 tax years are subject to examination as of March 31, 2020. We do not expect to record or realize any material unrecognized tax benefits during 2020. As a result of the adoption of ASC 326 - Credit Losses on January 1, 2020, the tax impact as a result of the incremental provision for expected credit losses from financial assets held at amortized cost has been reflected as a credit to retained earnings on January 1, 2020 to reflect the tax impact of increased credit reserves. Accordingly, $8.5 million of such provision for credit losses has been reflected as an income tax credit and deferred tax asset on the Company's Consolidated Statements of Financial Condition. As a result of the CARES Act, which was enacted during the first quarter of 2020 due to the COVID-19 pandemic, an additional $1.8 million income tax benefit and deferred tax asset was recognized on the Company's Consolidated Statements of Financial Condition. Refer to "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" for details. As a result of the adoption of ASU No. 2014-01, Investments-Equity Method and Joint Ventures: Accounting for Investments in Qualified Affordable Housing Projects , the amortization of our low-income housing credit investments has been reflected as income tax expense. Accordingly, $0.8 million and $0.6 million of such amortization has been reflected as income tax expense for the three months ended March 31, 2020 and 2019, respectively. The amount of affordable housing tax credits, amortization and tax benefits recorded as income tax expense for the three months ended March 31, 2020 were $0.7 million, $0.8 million and $0.2 million, respectively. The carrying value of the investment in affordable housing credits is $25.0 million at March 31, 2020, compared to $25.8 million at December 31, 2019.

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 - Overall (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, 2020 and December 31, 2019 by level in the valuation hierarchy (as described above): March 31, 2020 (Dollars in thousands) Quoted Significant Significant Total Fair Assets measured at fair value on a recurring basis: Available-for-sale securities: CMO $ — $ 333,398 $ — $ 333,398 FNMA MBS — 1,361,664 — 1,361,664 FHLMC MBS — 320,046 — 320,046 GNMA MBS — 33,292 — 33,292 Other assets — 12,364 — 12,364 Total assets measured at fair value on a recurring basis $ — $ 2,060,764 $ — $ 2,060,764 Liabilities measured at fair value on a recurring basis: Other liabilities $ — $ 9,325 $ — $ 9,325 Assets measured at fair value on a nonrecurring basis: Other investments $ — $ — $ 70,714 $ 70,714 Other real estate owned — — 4,825 4,825 Loans held for sale — 85,458 — 85,458 Total assets measured at fair value on a nonrecurring basis $ — $ 85,458 $ 75,539 $ 160,997 December 31, 2019 (Dollars in thousands) Quoted Significant Significant Total Fair Assets measured at fair value on a recurring basis: Available-for-sale securities: CMO $ — $ 340,230 $ — $ 340,230 FNMA MBS — 1,242,453 — 1,242,453 FHLMC MBS — 328,946 — 328,946 GNMA MBS — 33,285 — 33,285 Other assets — 4,884 — 4,884 Total assets measured at fair value on a recurring basis $ — $ 1,949,798 $ — $ 1,949,798 Liabilities measured at fair value on a recurring basis: Other liabilities $ — $ 3,918 $ — $ 3,918 Assets measured at fair value on a nonrecurring basis Other investments $ — $ — $ 70,046 $ 70,046 Other real estate owned — — 2,605 2,605 Loans held for sale — 83,872 — 83,872 Total assets measured at fair value on a nonrecurring basis $ — $ 83,872 $ 72,651 $ 156,523 There were no transfers between Level 1 and Level 2 of the fair value hierarchy during the three months ended March 31, 2020. 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. Our valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While we believe our 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. We believe that this Level 2 designation is appropriate under ASC 820-10 as, these securities are federal agency MBS with almost all fixed income securities, none are exchange traded, and all are priced by correlation to observed market data. For these securities we obtain 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 our equity investments without readily determinable fair values. These investments include our Visa Class B share holdings and certain other equity investments, all of which are categorized as Level 3. Our Visa Class B ownership includes shares acquired at no cost from our prior participation in Visa’s network while Visa operated as a cooperative as well as shares subsequently acquired through private transactions and auctions. Our equity investments without readily determinable fair values are held at cost, and are adjusted for any observable transactions during the reporting period. 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 our real estate owned was estimated using Level 3 inputs based on appraisals obtained from third parties. Loans held for sale The fair value of our 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. 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 and cash equivalents 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 Fair value is estimated using quoted prices for similar securities, which we obtain from a third party vendor. We use 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 us to validate the vendor’s methodology as described above in available-for-sale securities. Other investments Other investments includes our 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 Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by portfolio segments (see Note 2). For loans that reprice frequently, the book value approximates fair value. The fair values of other types of loans, 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. Other assets Other assets include the fair value of interest rate swaps and derivatives on the residential mortgage held for sale loan pipeline. Valuation of our interest rate swaps 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 . 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 us for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt. Other liabilities Other liabilities include the fair value of interest rate swaps, risk participation agreements and derivatives on the residential mortgage held for sale loan pipeline. Valuation of our interest rate swaps and risk participation agreements 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 . Off-balance sheet instruments The fair value of off-balance sheet instruments, including commitments to extend credit and standby letters of credit, approximates the recorded net deferred fee amounts, which are not significant. Because commitments to extend credit and letters of credit are generally not assignable by either us or the borrower, they only have value to us and the borrower. See Note 2 for the impact to the unfunded lending commitments reserve based on our CECL adoption. Assets measured at fair value using significant unobservable inputs (Level 3) The following table provides a description of the valuation technique and significant unobservable inputs for the Company's assets classified as Level 3 and measured at fair value on a nonrecurring basis: March 31, 2020 Financial Instrument Fair Value Valuation Technique(s) Unobservable Input Range (Weighted Average) Other investments $ 70,714 Observed market comparable transactions Period of observed transactions July 2019 - January 2020 Other real estate owned $ 4,825 Fair market value of collateral Costs to sell 10.0% - 20.0% (10.0%) The book value and estimated fair value of our financial instruments are as follows: March 31, 2020 December 31, 2019 (Dollars in thousands) Fair Value Book Value Fair Value Book Value Fair Value Financial assets: Cash and cash equivalents Level 1 $ 505,110 $ 505,110 $ 571,752 $ 571,752 Investment securities available-for-sale Level 2 2,048,400 2,048,400 1,944,914 1,944,914 Investment securities held-to-maturity, net Level 2 134,047 137,374 133,601 136,625 Other investments Level 3 70,714 70,714 70,046 70,046 Loans, held for sale Level 2 85,458 85,458 83,872 83,872 Loans, net (1) Level 3 8,411,689 8,475,886 8,424,464 8,580,015 Stock in FHLB of Pittsburgh Level 2 33,988 33,988 21,097 21,097 Accrued interest receivable Level 2 39,134 39,134 38,094 38,094 Other assets Level 2 12,364 12,364 4,884 4,884 Financial liabilities: Deposits Level 2 9,709,354 9,710,432 9,586,857 9,575,394 Borrowed funds Level 2 401,285 404,955 489,288 489,561 Standby letters of credit Level 3 505 505 623 623 Accrued interest payable Level 2 5,797 5,797 3,103 3,103 Other liabilities Level 2 9,325 9,325 3,918 3,918 (1) Includes reverse mortgage loans.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	15. DERIVATIVE FINANCIAL INSTRUMENTS Risk Management Objective of Using Derivatives We are exposed to certain risks arising from both economic conditions and our business operations. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of our assets and liabilities. We manage a matched book with respect to our derivative instruments in order to minimize our net risk exposure resulting from such transactions. Fair Values of Derivative Instruments The table below presents the fair value of our derivative financial instruments as well as their location on the unaudited Consolidated Statements of Financial Condition as of March 31, 2020.

To accomplish this objective, we primarily use interest rate swaps as part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of fixed amounts from a counterparty in exchange for us making variable-rate payments over the life of the agreements without exchange of the underlying notional amount. 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. During the three months ended March 31, 2020, such derivatives were used to hedge the variable cash flows associated with a variable rate loan pool. Amounts reported in accumulated other comprehensive income (loss) related to derivatives are reclassified to interest income as interest payments are received on our variable-rate pooled loans. During the next twelve months, we estimate that $0.6 million will be reclassified as an increase to interest income. During the three months ended March 31, 2020, $0.1 million was reclassified into interest income. We are hedging our exposure to the variability in future cash flows for forecasted transactions over a maximum period of one month (excluding forecasted transactions related to the payment of variable interest on existing financial instruments). As of March 31, 2020, we had three outstanding interest rate derivatives with an aggregate notional amount of $75.0 million that were designated as cash flow hedges of interest rate risk.

We also have agreements with certain derivative counterparties that contain a provision where if we fail to maintain our status as a well-capitalized or adequately capitalized institution, then the counterparty could terminate the derivative positions and we would be required to settle our obligations under the agreements. As of March 31, 2020, the termination value of derivatives designated as hedging instruments in a net asset position related to these agreements was $1.3 million. These agreements were terminated in April 2020.

Segment Reporting [Abstract]
SEGMENT INFORMATION	16. 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. We evaluate performance based on pretax net income relative to resources used, and allocate resources based on these results. The accounting policies applicable to our segments are those that apply to our preparation of the accompanying unaudited Consolidated Financial Statements. Based on these criteria, we have identified three segments: WSFS Bank, Cash Connect ® , and Wealth Management. The WSFS Bank segment provides financial products to commercial and retail customers. Retail and Commercial Banking, Commercial Real Estate Lending and other banking business units are operating departments of WSFS Bank. These departments share the same regulator, 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 in accordance with ASC 280. Our 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 retail 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. WSFS Wealth Investments provides financial advisory services along with insurance and brokerage products. Cypress, a registered investment adviser, is a fee-only wealth management firm managing a “balanced” investment style portfolio focused on preservation of capital and generating current income. West Capital, a registered investment adviser, is a fee-only wealth management firm operating under a multi-family office philosophy to provide customized solutions to institutions and high-net-worth individuals. The institutional trust division of WSFS, WSFS Institutional Services, provides trustee, agency, bankruptcy administration, custodial and commercial domicile services to institutional and corporate clients. The personal trust division of WSFS, Christiana Trust, provides personal trust and fiduciary services to families and individuals across the U.S. 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. WSFS Wealth Client Management serves high-net-worth clients by delivering credit and deposit products and partnering with other Wealth Management units to provide comprehensive solutions to clients.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	17. COMMITMENTS AND CONTINGENCIES Secondary Market Loan Sales Given the current interest rate environment and our overall asset and liability management approach, we typically sell newly originated residential mortgage loans in the secondary market to mortgage loan aggregators and on a more limited basis, to government sponsored entities (GSEs) such as FHLMC, FNMA, and the FHLB. Loans held for sale are reflected on our unaudited Consolidated Statements of Financial Condition at fair value with changes in the value reflected in our unaudited Consolidated Statements of Income. Gains and losses are recognized at the time of sale. We periodically retain the servicing rights on residential mortgage loans sold which results in monthly service fee income. The mortgage servicing rights are included in our intangible assets in our unaudited Consolidated Statements of Financial Condition. Otherwise, we sell loans with servicing released on a nonrecourse basis. Rate-locked loan commitments that we intend to sell in the secondary market are accounted for as derivatives under ASC 815, Derivatives and Hedging (ASC 815) . We do 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 no repurchases during the three months ended March 31, 2020 as compared to one repurchase for $0.2 million during the three months ended March 31, 2019. Swap Guarantees We entered into agreements with four unrelated financial institutions whereby those financial institutions entered into interest rate derivative contracts (interest rate swap transactions) directly with customers referred to them by us. 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. Fees received for the guarantee of payment are accounted for in accordance with ASC 460 - Guarantees , and amortized over the life of the loan. At March 31, 2020 and December 31, 2019, there were 202 and 172 variable-rate to fixed-rate swap transactions between the third-party financial institutions and our customers, respectively. The initial notional aggregate amount was approximately $1.0 billion at March 31, 2020 compared to $941.0 million at December 31, 2019. At March 31, 2020, maturities ranged from under 1 year to 15 years. The aggregate net market value of these swaps to the customers was a liability of $84.3 million at March 31, 2020 and a liability of $26.4 million at December 31, 2019. At March 31, 2020, 200 swaps, with a liability of $85.5 million, were in paying positions to a third party; however, none of our customers were in default of the swap agreements. There were no payments made by the Company under the agreements at both March 31, 2020 and December 31, 2019. Unfunded Lending Commitments At March 31, 2020 and December 31, 2019, the unfunded lending commitments were $4.3 million and $1.5 million, respectively. The balance at March 31, 2020 was determined using the CECL methodology, which included a $3.0 million adjustment to retained earnings at the time of adoption. A credit for unfunded lending commitments of $0.2 million was recognized during the three months ended March 31, 2020, and a provision for unfunded lending commitments of $0.2 million was recognized during the three months ended March 31, 2019.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	19. RELATED PARTY TRANSACTIONS In the ordinary course of business, from time to time we enter into transactions with related parties, including, but not limited to, our officers and directors. These transactions are made on substantially the same terms and conditions, including interest rates and collateral requirements, as those prevailing at the same time for comparable transactions with other customers. They do not, in the opinion of management, involve greater than normal credit risk or include other features unfavorable to us. Any related party loans exceeding $0.5 million require review and approval by the Board of Directors. During the three months ended March 31, 2020 and 2019, there were no loans originated to related parties exceeding $0.5 million.

LEGAL AND OTHER PROCEEDINGS	20. LEGAL AND OTHER PROCEEDINGS In accordance with the current accounting standards for loss contingencies, we establish reserves for litigation-related matters that arise in the ordinary course of our 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, our defense of litigation claims may result in legal fees, which we expense as incurred. As previously disclosed, on February 27, 2018, we entered into a settlement agreement with Universitas Education, LLC (Universitas) to resolve arbitration claims related to services provided by Christiana Bank and Trust Company (CB&T) prior to its acquisition by WSFS in December 2010. In accordance with the litigation settlement, we paid Universitas $12.0 million to fully settle the claims. During the third quarter of 2018, WSFS recovered $7.9 million in settlement and legal costs from insurance carriers that provided coverage relating to the Universitas matter. WSFS is pursuing all of its rights and remedies to recover the remaining amounts relating to the Universitas proceeding, including the Universitas settlement payment, legal fees and related costs, by enforcing the indemnity right in the 2010 purchase agreement by which WSFS acquired CB&T. In March 2017, Nature’s Healing Trust (NHT) filed a complaint against WSFS Bank in the Delaware Court of Chancery. NHT asserts that WSFS Bank failed to provide timely notice concerning the possible lapse of two life settlement policies (aggregate face amount of $6.3 million) held in the trust. NHT asserts claims against WSFS Bank for breach of contract, breach of fiduciary duty, and negligence, and seeks the face value of the policies. WSFS Bank disputes the factual allegations and denies liability. WSFS Bank has, in accordance with its normal procedures, notified its insurance carriers of a possible claim. WSFS Bank is vigorously defending itself in this matter and believes it has valid factual and legal defenses. There were no material changes or additions to other significant pending legal or other proceedings involving us other than those arising out of routine operations.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	21. SUBSEQUENT EVENTS The Company evaluated subsequent events in accordance with ASC Topic 855 and determined that the following qualifies as a non-recognized subsequent event: Coronavirus Aid, Relief, and Economic Security (CARES) Act On April 6, 2020, the Company began participating in the Paycheck Protection Program (PPP), a stimulus response to the potential economic impacts of COVID-19 that is backed by the U.S. Small Business Administration (SBA). During the second quarter of 2020, through the date of this Quarterly Report on Form 10-Q, the Company has submitted and received approvals for 4,732 applications for $971.2 million in PPP loans to our customers. The Company is also providing a number of customer relief programs in its commercial and retail portfolios, such as payment deferrals or interest only payments on loans and leases. The CARES Act allows financial institutions to exclude eligible modifications from TDR reporting under its loan forbearance program. Eligible modification must be related to the COVID-19 pandemic, executed on a loan that was not more than 30 days past due as of December 31, 2019 and executed between March 1, 2020 and the earlier of 60 days after the date of the termination of the national emergency or December 31, 2020. During the second quarter of 2020, through the date of this Quarterly Report on Form 10-Q, the Company modified approximately $2.2 billion of loans and leases to provide its customers this monetary relief.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2020
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation In preparing the unaudited Consolidated Financial Statements, we are 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 as well as increased post-retirement benefits expense. Our 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, 2020. These unaudited, interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2019 (the 2019 Annual Report on Form 10-K) that was filed with the SEC on March 2, 2020 and is available at www.sec.gov or on our website at www.wsfsbank.com . All significant intercompany accounts and transactions were eliminated in consolidation.
Loans	Loans Loans held for investment are recorded at amortized cost, net of allowance for credit losses. Amortized cost is the amount at which a financial asset is originated or acquired, adjusted for the amortization of premium and discount, net deferred fees or costs, collection of cash, and write-offs. Interest income on loans is recognized using the level yield method. Loan origination fees, commitment fees and direct loan origination costs are deferred and recognized over the life of the related loans using a level yield method over the period to maturity.
Allowance for Credit Losses - Loans and Leases	Allowance for Credit Losses - Loans and Leases We establish our 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 management's current estimate of expected credit losses, including our portfolio mix and segmentation, modeling methodology, historical loss experience, relevant available information from internal and external sources relating to reasonable and supportable forecasts about future economic conditions, prepayment speeds, and qualitative adjustment factors. The Company's portfolio segments, established based on similar risk characteristics and loss behaviors, are: • Commercial and industrial, owner-occupied commercial, commercial mortgages, construction and commercial small business leases (collectively, commercial loans), and • Residential, equity secured lines and loans, installment loans, unsecured lines of credit and education loans (collectively, retail loans). Expected credit losses are estimated over the contractual term, adjusted for expected prepayments and recoveries. The contractual term excludes any extensions, renewals and modifications unless the Company has reasonable expectations at the reporting date that it will result in a TDR or they are not unconditionally cancellable. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. 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 retail loans, and each portfolio segment is further segmented by internally assessed risk ratings. Management uses a third-party economic forecast to modify the calculated historical loss rates of the portfolio segments. Our economic 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 we believe this to be reasonable and supportable in the current environment. The economic forecast and reversion periods will be evaluated periodically by management 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). 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 retail loans is calculated based solely on average net loss rates over the same look-back period. Our current look-back period is 37 quarters which allows us to ensure that 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 TDRs, are not included in the collective basis evaluation. When it is probable we 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 one of 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 is 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), 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 in our model can add to or subtract from quantitative reserves. Our 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 our loan ratings and allowance for credit losses and the Bank’s internal loan review department performs loan reviews. Accrued interest receivable on loans is excluded from the estimate of credit losses and is included in Accrued interest receivable on the Consolidated Statements of Financial Condition.
Past Due and Nonaccrual Loans	Past Due and Nonaccrual Loans Past due loans are defined as loans contractually past due 30 days or more as to principal or interest payments but which remain in accrual status because they 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 management, 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 management’s assessment of the ultimate collectability of principal and interest. Loans are returned to accrual status when we assess 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). Unless loans are well-secured and collection is imminent, for loans greater than 90 days past due 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 resulting in a concession to the borrower experiencing financial difficulty, is considered a troubled debt restructuring (TDR). Principal balances are generally not forgiven when a loan is modified as a TDR. Nonaccruing restructured loans remain in nonaccrual status until there has been a period of sustained repayment performance demonstrated, as noted above, and repayment is reasonably assured. For additional detail regarding past due and nonaccrual loans, see Note 8.
Debt Securities	Debt Securities Investments in debt securities are classified into one of the following three categories and accounted for as follows: • Securities purchased with the intent of selling them in the near future are classified as “trading” and reported at fair value, with unrealized gains and losses included in earnings. • Securities purchased with the positive intent and ability to hold to maturity are classified as “held-to-maturity” and reported at amortized cost. • Securities not classified as either trading or held-to-maturity are classified as “available-for-sale” and reported at fair value, with unrealized gains and losses excluded from earnings and reported, net of tax, as a separate component of stockholders’ equity in accumulated other comprehensive income (loss). Realized gains and losses on sales of investment and mortgage-backed securities (MBS) are determined using the specific identification method. All sales are made without recourse. Debt securities mostly include mortgage-backed securities (MBS), municipal bonds, and U.S. government and agency securities. Premiums and discounts on MBS collateralized by residential 1-4 family loans are recognized in interest income using a level yield method over the period to expected maturity. Premiums and discounts on all other securities are recognized on a straight line basis over the period to expected maturity, with the exception of premiums on callable debt securities, which are recognized over the period to the earliest call date. The fair value of debt securities is primarily obtained from third-party pricing services. Implicit in the valuation of MBS are estimated prepayments based on historical and current market conditions. A debt security is placed on nonaccrual status at the time any principal or interest payments are contractually past due 90 days or more. Interest accrued but not received for a security placed on nonaccrual status is reversed against interest income. Our investment portfolio is reviewed each quarter for indications of potential credit losses. Refer to the respective held-to-maturity and available-for-sale debt securities sections for management's discussion of the allowance for credit loss for each portfolio. Allowance for Credit Losses - Held-to-Maturity Debt Securities We follow Accounting Standards Codification (ASC) 326-20, Financial Instruments - Credit Loss - Measured at Amortized Cost, to measure expected credit losses on held-to-maturity debt securities on a collective basis by security investment grade. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The Company classifies the held-to-maturity debt securities into the following major security types: state and political subdivisions, and foreign bonds. These securities are highly rated with a history of no credit losses, and are assigned ratings based on the most recent data from ratings agencies depending on the availability of data for the security. Credit ratings of held-to-maturity debt securities, which are a significant input in calculating the expected credit loss, are reviewed on a quarterly basis. Accrued interest receivable on held-to-maturity debt securities is excluded from the estimate of credit losses and is included in Accrued interest receivable on the Consolidated Statements of Financial Condition. Allowance for Credit Losses - Available-for-Sale Debt Securities We follow ASC 326-30, Financial Instruments - Cre dit Loss - Available-for-Sale Debt Securities, which provides guidance related to the recognition of and expanded disclosure requirements for expected credit losses on available-for-sale debt securities. For available-for-sale debt securities in an unrealized loss position, the Company first evaluates whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either criteria is met, the security's amortized cost basis is reduced to fair value and recognized as a reduction to Noninterest income in the Consolidated Statements of Income. For debt securities available-for-sale which the Company does not intend to sell, or it is not likely the security would be required to be sold before recovery, we evaluate whether a decline in fair value has resulted from credit losses or other adverse factors, such as a change in the security's credit rating. In assessing whether a credit loss exists, the Company compares the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance is recorded, limited to the fair value of the security. Management performs this analysis on a quarterly basis to review the conditions and risks associated with the individual securities. Credit losses on an impaired security shall continue to be measured using the present value of expected future cash flows. Any impairment not recorded through an allowance for credit loss is included in other comprehensive income (loss), net of the tax effect. We are required to use our judgment in determining impairment in certain circumstances. For additional detail regarding debt securities, see Note 6.
Unfunded Lending Commitments	Unfunded Lending Commitments For unfunded lending commitments, the Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The estimate includes consideration of the probability of default and utilization rate at default to calculate expected credit losses on commitments expected to be funded over its estimated life of one year, based on historical losses, and qualitative adjustment factors. The allowance for credit losses for off-balance sheet exposures is included in Other liabilities on the Consolidated Statements of Financial Condition and the provision for credit losses for off-balance sheet exposure is included in Other operating expense on the Consolidated Statements of Income.
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Accounting Guidance Adopted in 2020 ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) . ASU 2016-13 replaces the incurred loss impairment methodology in current GAAP with the current expected credit losses (CECL) methodology which requires management consideration and judgment of a broader range of information to determine credit loss estimates. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326 , clarifying that operating lease receivables are not within the scope of Topic 326. In December 2018, federal regulators issued a final rule related to regulatory capital and CECL (Regulatory Capital Rule: Implementation and Transition of the Current Expected Credit Losses Methodology for Allowances and Related Adjustments to the Regulatory Capital Rule and Conforming Amendments to Other Regulations) , intended to provide regulatory capital relief for entities transitioning to CECL. In May 2019, the FASB issued ASU No. 2019-05, Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief , providing entities the option to irrevocably elect the fair value option on eligible financial instruments, which excludes held-to-maturity debt securities. In November 2019, the FASB issued ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, clarifying guidance on expected recoveries for purchased credit deteriorated financial assets, accrued interest receivable and collateral maintenance provisions and providing transition relief for troubled debt restructurings. In March 2020, the FASB issued ASU No. 2020-03, Codification Improvements to Financial Instruments , clarifying the contractual term of a net investment in a lease and the requirement to establish an allowance for credit loss when an entity regains control of sold financial assets. While the CARES Act provides an option to defer implementation of the CECL methodology, the Company adopted this guidance on January 1, 2020, using the modified retrospective approach for financial assets recorded at amortized cost with the exception of purchase credit deteriorated (PCD) assets, which were previously classified as purchase credit impaired (PCI) accounted for under ASC 310-30, adopted using the prospective approach. The cumulative effect of the adoption resulted in a $30.4 million decrease to the beginning balance of retained earnings as of January 1, 2020. Results and disclosures for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. For further details on the impact of the adoption, accounting policies, elections, and practical expedients applied, see updated Significant Accounting Policies and CECL disclosures throughout the Notes to the Consolidated Financial Statements. The following table illustrates the impact of ASC 326 for our loans, leases, purchased financial assets, debt securities, other assets and unfunded lending commitments compared to the incurred loss approach, as disclosed prior to our adoption on January 1, 2020.

See Note 14 for changes to financial statement disclosures resulting from our adoption of this standard. ASU No. 2018-14, Compensation-Retirement Benefits - Defined Benefit Plans-General (Topic 715): In August 2018, the FASB issued ASU No. 2018-14, Compensation-Retirement Benefits - Defined Benefit Plans-General (Topic 715) which applies to all employers that provide defined benefit pension or other postretirement benefit plans for their employees. The new guidance modifies, adds and removes certain disclosures aimed to improve the overall usefulness of the disclosure requirements to financial statement users. The guidance is effective for annual periods beginning after December 15, 2020. Early adoption is permitted. Use of the retrospective method is required. The Company early adopted this standard on January 1, 2020. See Note 12 for changes to financial statement disclosures resulting from our adoption of this standard. ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Topic 350) : In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Topic 350) . The new guidance provides clarity on capitalizing and expensing implementation costs for cloud computing arrangements in a service contract. If an implementation cost is capitalized, the cost should be recognized over the noncancellable term and periodically assessed for impairment. The guidance is effective in annual and interim periods in fiscal years beginning after December 15, 2019. Early adoption is permitted. Adoption can be applied retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company adopted this standard on January 1, 2020, on a prospective basis with no impact to the Consolidated Financial Statements at the time of adoption. ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments: In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. The new guidance amends ASU 2016-13 to address topics related to accrued interest receivables, recoveries, disclosures, and provides certain other clarifications. The new guidance also amends ASU 2017-12 to provide clarification on certain hedge accounting topics and transition requirements. Lastly, the new guidance amends ASU 2016-01, Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities , to add clarifying guidance when using the measurement alternative under ASC 820, among certain other clarifications. The guidance is effective for annual periods beginning after December 15, 2019. Early adoption is permitted. Adoption is required on a prospective, modified-retrospective or retrospective basis, depending on the amendment. The Company included the amendments related to ASU 2016-13 as part of our CECL guidance implementation and adoption at January 1, 2020. The Company adopted other amendments within this guidance on January 1, 2020 with no impact to the Consolidated Financial Statements at the time of adoption. Accounting Guidance Pending Adoption at March 31, 2020 ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes : In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.
