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) and Christiana Trust Company of Delaware (Christiana Trust DE). We also have one unconsolidated subsidiary, WSFS Capital Trust III. WSFS Bank has four wholly owned subsidiaries: Beneficial Equipment Finance Corporation (BEFC), WSFS Investment Group, Inc. (WSFS Wealth Investments), 1832 Holdings, Inc., and WSFS SPE Services, LLC, 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 127 offices located in Pennsylvania (56) , Delaware (49), New Jersey (20), Virginia (1) and Nevada (1) and through our website at www.wsfsbank.com . 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 (formerly Neumann Finance Company). 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 loan and lease losses and reserves for lending-related commitments, goodwill, intangible assets, post-retirement benefit obligations, the fair value of financial instruments, income taxes and other-than-temporary impairment (OTTI). Among other effects, changes to these estimates could result in future impairments of investment securities, goodwill and intangible assets, the establishment of the allowance and lending-related commitments 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, 2019. 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, 2018 (the 2018 Annual Report on Form 10-K) that was filed with the SEC on February 28, 2019 and is available at www.sec.gov or on our website at www.wsfsbank.com . All significant intercompany transactions were eliminated in consolidation. Business Combinations On March 1, 2019, we acquired Beneficial Bancorp, Inc. (Beneficial), including its subsidiary Beneficial Bank, a community bank headquartered in Philadelphia, Pennsylvania, creating the largest, premier, locally-headquartered bank in the Greater Delaware Valley. Beneficial merged with and into WSFS, with WSFS continuing as the surviving corporation and simultaneously, Beneficial Bank merged with and into WSFS Bank, with WSFS Bank continuing as the surviving bank. This acquisition grew our market share, deepened our presence in the Philadelphia, southeastern Pennsylvania and New Jersey markets, and enhanced our customer base. The results of Beneficial's operations are included in our unaudited Consolidated Financial Statements since the date of the acquisition. See Note 3 for further information.

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 2018 Annual Report on Form 10-K. Those significant accounting policies remain unchanged at September 30, 2019, except as described below: Leases We account for our leases in accordance with ASC 842 - Leases . Most of our leases are recognized on the balance sheet by recording a right-of-use asset and lease liability for each lease. The right-of-use asset represents the right to use the asset under lease for the lease term, and the lease liability represents the contractual obligation to make lease payments. The right-of-use asset is tested for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. As a lessee, WSFS enters into operating leases for certain bank branches, office space, and office equipment. The right-of-use assets and lease liabilities are initially recognized based on the net present value of the remaining lease payments which include renewal options where management is reasonably certain they will be exercised. The net present value is determined using the incremental collateralized borrowing rate at commencement date. The right-of-use asset is measured at the amount of the lease liability adjusted for any prepaid rent, lease incentives and initial direct costs incurred. The right-of-use asset and lease liability is amortized over the individual lease terms. Lease expense for lease payments is recognized on a straight-line basis over the lease term. As a lessor, WSFS provides direct financing to our customers through our equipment and small-business leasing business. Direct financing leases are recorded at the aggregate of minimum lease payments net of unamortized deferred lease origination fees and costs and unearned income. Interest income on direct financing leases is recognized over the term of the lease. Origination fees and costs are deferred, and the net amount is amortized to interest income over the estimated life of the lease. RECENT ACCOUNTING PRONOUNCEMENTS Accounting Guidance Adopted in 2019 ASU No. 2016-02, Leases (Topic 842): In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . This ASU revises lessee accounting. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for substantially all leases. The new lease guidance also simplifies the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. ASU 2016-02 is effective for the first interim period within annual periods beginning after December 15, 2018, with early adoption permitted. Adoption using the comparative modified retrospective transition approach is required; however, in July 2018, the FASB issued ASU 2018-11, Leases-Targeted Improvements , which provides an optional transition method whereby comparative periods presented in the financial statements in the period of adoption do not need to be restated under Topic 842. The Company adopted this guidance and its related amendments on January 1, 2019 using the transition option in ASU 2018-11 and the results of this adoption are recorded in the Consolidated Statements of Financial Condition. See Note 9 for additional disclosures resulting from our adoption of this standard. ASU No. 2019-01, Leases (Topic 842), Codification Improvements: Subsequent to adopting ASU 2016-02, in March 2019, the FASB issued ASU No. 2019-01, Leases (Topic 842) : Codification Improvements , which makes targeted changes to lessor accounting and clarifies interim transition disclosure requirements upon adopting Topic 842. The guidance is effective for annual periods beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. The Company adopted this guidance on March 31, 2019. See Note 9 for additional disclosures resulting from our adoption of this standard. ASU No. 2017-08, Premium Amortization on Purchased Callable Debt Securities: In March 2017, the FASB issued ASU No. 2017-08, Premium Amortization on Purchased Callable Debt Securities . The new guidance requires the amortization period for certain non-contingent callable debt securities held at a premium to end at the earliest call date of the debt security. If the call option is not exercised at the earliest call date, the guidance requires the debt security's effective yield to be reset based on the contractual payment terms of the debt security. The guidance is effective in annual and interim periods in fiscal years beginning after December 15, 2018. Early adoption is permitted. Use of the modified retrospective method, with a cumulative-effect adjustment to retained earnings is required. The Company adopted this standard on January 1, 2019, on a modified retrospective basis and the adoption did not have an effect on the Consolidated Financial Statements. ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities (Topic 815): In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities (Topic 815) . The new guidance changes both the designation and measurement guidance for qualifying hedging relationships and simplifies the presentation of hedge results. Specifically, the guidance eliminates the requirement to separately measure and report hedge ineffectiveness and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. Further, the new guidance provides entities the ability to apply hedge accounting to additional hedging strategies as well as permits a one-time reclassification of eligible to be hedged instruments from held to maturity to available for sale upon adoption. The guidance is effective in annual and interim periods beginning after December 15, 2018. Early adoption is permitted. Adoption using the modified retrospective approach is required for hedging relationships that exist as of the date of adoption; presentation and disclosure requirements are applied prospectively. The Company adopted this standard on January 1, 2019, on a modified retrospective basis for existing hedging relationships and on a prospective basis for presentation and disclosure requirements. The adoption of this standard did not have an effect on the Consolidated Financial Statements. See Note 15 for additional disclosures resulting from our adoption of this standard. ASU No. 2018-16, Derivatives and Hedging - Inclusion of the Secured Overnight Financial Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes (Topic 815): In October 2018, the FASB issued ASU No. 2018-16, Derivatives and Hedging - Inclusion of the Secured Overnight Financial Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes (Topic 815) . The new guidance applies to all entities that elect to apply hedge accounting to benchmark interest rate hedges under Topic 815. It permits the use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes in addition to the existing applicable rates. The guidance is required to be adopted concurrently with ASU 2017-12, on a prospective basis for qualifying new or redesignated hedging relationships entered into on or after adoption. The Company adopted this standard on January 1, 2019 on a prospective basis and the adoption did not have an effect on the Consolidated Financial Statements. Accounting Guidance Pending Adoption at September 30, 2019 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 and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses. Purchased credit impaired assets will receive an allowance account at the acquisition date that represents a component of the purchase price allocation. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses, with such allowance limited to the amount by which fair value is below amortized cost. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326 , which clarifies that receivables arising from operating leases are not within the scope of Topic 326. In December 2018, regulators issued a final rule related to regulatory capital ( 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 ) which is intended to provide regulatory capital relief to entities transitioning to CECL. In May 2019, the FASB issued ASU No. 2019-05, Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief , which provides entities the option to irrevocably elect the fair value option on financial instruments within the scope of both ASC 326-20 and ASC 825-10 upon adoption of ASU 2016-13. This guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The Company will adopt this guidance on January 1, 2020. The adoption of this guidance will affect our accounting for loans, leases, purchased financial assets, debt securities, and unfunded commitments. A cross-functional team from Finance, Credit, and Information Technology is leading the implementation efforts, and continue to assess the impact of this guidance on the Company’s Consolidated Financial Statements, internal systems, accounting policies, processes and related internal controls. We have completed the implementation of our software solution and a third-party specialist has completed an independent model review of the solution. Further, we have defined our loan portfolio categories, credit loss methodologies, reasonable and supportable forecast and reversion periods. Our implementation efforts continue to focus on our comprehensive evaluation of model outputs based on the implementation decisions made to date, as well as defining the framework and evaluating the impact of qualitative adjustment factors, and refining our allowance for credit losses (ACL) governance framework. We are in the process of finalizing our accounting policies and reporting requirements under the guidance as well as implementation and transition rules issued by regulators. As necessary, we will continue to consult with third-party experts and specialists to assist with our adoption efforts. Our implementation efforts to date suggest that adoption may materially increase the allowance for credit losses and decrease capital levels; however, the extent of these impacts will depend on the composition and asset quality of the portfolio, macroeconomic conditions, and continued refinement of significant estimates and judgments by management at the time of adoption. 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 does not expect the application of this guidance to have a material impact on the Consolidated Financial Statements. 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 does not expect the application of this guidance to have a material impact on the Consolidated Financial Statements. 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. Our preliminary review of this guidance to date suggests that adoption may result in a material amount of implementation costs being deferred; however, the extent of the impact will depend on the cloud computing implementations occurring 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 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 will evaluate the amendments to ASU 2016-13 in conjunction with our overall evaluation of ASU 2016-13. For other amendments within this guidance, the Company does not expect the application of this guidance to have a material impact on the Consolidated Financial Statements.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	3. BUSINESS COMBINATIONS Beneficial Bancorp, Inc. On March 1, 2019, we 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 our 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. While the valuation of acquired assets and liabilities is nearly completed, management continues to assess the values of certain assets and liabilities which may be subject to adjustment as additional information is obtained about the facts and circumstances that existed at the acquisition date. When the valuation is final, any changes to the valuation of acquired assets and liabilities could result in adjustments to identified intangibles and goodwill. The fair values of assets acquired and liabilities assumed is expected to be finalized during the measurement period, which ends one year from the closing date. The following table summarizes the consideration transferred and the fair values of identifiable assets acquired and liabilities assumed: (Dollars in thousands) Consideration Transferred: Fair Value Common shares issued (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 619,853 Loans and leases, net 3,711,246 Premises and equipment 69,873 Deferred income taxes 18,485 Bank owned life insurance 82,510 Core deposit intangible 85,053 Servicing rights intangible 2,466 Other assets 135,862 Total assets 5,029,659 Liabilities assumed: Deposits 4,056,506 Other liabilities 101,897 Total liabilities 4,158,403 Net assets acquired: 871,256 Goodwill resulting from acquisition of Beneficial $ 306,951 The following table details the change 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 (3,150) Loans 911 Premises and equipment (741) Deferred income taxes 985 Other assets (418) Deposits 790 Other liabilities (1,158) Adjusted goodwill resulting from the acquisition of Beneficial as of September 30, 2019 $ 306,951 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. Acquired loans are initially recorded at their fair values as of the acquisition date. The fair value is based on a discounted cash flow methodology that uses assumptions as to credit risk, default rates, collateral values, and loss severity, along with estimated prepayment rates. Loans that have deteriorated in credit quality since their origination, and for which it is probable that all contractual cash flows will not be received, are accounted for in accordance with ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality . For additional information regarding purchased impaired loans, see Note 7 to the unaudited Consolidated Financial Statements. The acquired investment portfolio had a fair value of $619.9 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 which is being amortized over ten years using a straight-line amortization methodology. The fair value of the core deposit intangible was determined based on modeling assumptions that take into consideration customer attrition, 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” and “Restructuring” expense line items, respectively, on the Consolidated Statements of Income.

Revenue from Contract with Customer [Abstract]
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 September 30, Nine Months Ended September 30, (Dollars in thousands) 2019 2018 2019 2018 Bailment fees $ 6,580 $ 7,188 $ 20,388 $ 19,869 Interchange fees 6,234 3,766 17,073 11,073 Other card and ATM fees 301 285 846 811 Total credit/debit card and ATM income $ 13,115 $ 11,239 $ 38,307 $ 31,753 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 who transferred the property (the bailor) retains ownership interest of the property. In the event that the bailee files for bankruptcy protection, the property is not included in the bailee's assets. The bailee pays an agreed-upon fee for the use of the bailor's property in exchange for the bailor allowing use of the assets at the bailee's site. Bailment fees are earned from cash that is made available for customers' use at an offsite location, such as cash located in an ATM at a customer's place of business. These fees are typically indexed to a market interest rate. This revenue stream generates fee income through monthly billing for bailment services. Credit/debit card and ATM income also includes interchange fees. Interchange fees are paid by a merchant's bank to a bank that issued a debit or credit card used in a transaction to compensate the issuing bank for the value and benefit the merchant receives from accepting electronic payments. These revenue streams generate fee income at the time a transaction occurs and are recorded as revenue at the time of the transaction. Investment management and fiduciary income The following table presents the components of investment management and fiduciary income: Three Months Ended September 30, Nine Months Ended September 30, (Dollars in thousands) 2019 2018 2019 2018 Trust fees $ 6,632 $ 5,932 $ 19,884 $ 17,298 Wealth management and advisory fees 3,827 4,097 11,104 12,164 Total investment management and fiduciary income $ 10,459 $ 10,029 $ 30,988 $ 29,462 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. 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 September 30, Nine Months Ended September 30, (Dollars in thousands) 2019 2018 2019 2018 Service fees $ 3,188 $ 2,663 $ 9,083 $ 7,877 Return and overdraft fees 2,797 1,885 7,341 5,662 Other deposit service fees 154 122 564 425 Total deposit service charges $ 6,139 $ 4,670 $ 16,988 $ 13,964 Deposit service charges includes revenue earned from our core deposit products, certificates of deposit, and brokered deposits. We generate 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 September 30, Nine Months Ended September 30, (Dollars in thousands) 2019 2018 2019 2018 Managed service fees $ 3,628 $ 3,169 $ 10,195 $ 9,100 Currency preparation 823 863 2,413 2,406 ATM insurance 644 586 1,923 1,781 Miscellaneous products and services 1,942 2,041 7,947 6,391 Total other income $ 7,037 $ 6,659 $ 22,478 $ 19,678 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. For the nine months ended September 30, 2019, "Miscellaneous products and services" included income related to a non-recurring transfer of client accounts to a departing Wealth investment adviser, in accordance with the buy-out provisions of the adviser's contract. 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.

INVESTMENT SECURITIES	6. INVESTMENT SECURITIES The following tables detail the amortized cost and the estimated fair value of our investments in available-for-sale and held-to-maturity debt securities as well as our equity investments. None of our investments in debt securities are classified as trading.

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. Investment securities with fair market values aggregating $1.2 billion and $914.5 million were pledged as collateral for retail customer repurchase agreements, municipal deposits, and other obligations as of September 30, 2019 and December 31, 2018, respectively. During the nine months ended September 30, 2019, we sold $602.5 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 $23.7 million resulted in realized gains of less than $0.1 million and no realized losses. During the nine months ended September 30, 2018, we sold $7.0 million of debt securities categorized as available for sale, resulting in realized gains of less than $0.1 million and no realized losses. The cost basis of all debt securities sales is based on the specific identification method. During the nine months ended September 30, 2018, we sold $6.2 million of equity securities, specifically Visa Class B shares, resulting in realized gains of $3.8 million and no realized losses. There were no such sales during the nine months ended September 30, 2019. As of September 30, 2019 and December 31, 2018, our debt securities portfolio had remaining unamortized premiums of $16.7 million and $12.7 million, respectively, and unaccreted discounts of $3.5 million and $2.5 million, respectively. For debt securities with unrealized losses, the table below shows our gross unrealized losses and fair value by investment category and length of time that individual debt securities were in a continuous unrealized loss position at September 30, 2019.

Total unrealized losses on these securities were $1.5 million at September 30, 2019. The temporary impairment is the result of changes in market interest rates subsequent to purchase. Our investment portfolio is reviewed each quarter for indications of OTTI. This review includes analyzing the length of time and the extent to which the fair value has been lower than the amortized cost, the financial condition and near-term prospects of the issuer, including any specific events which may influence the operations of the issuer and our intent and ability to hold the investment for a period of time sufficient to allow for full recovery of the unrealized loss. We evaluate our intent and ability to hold debt securities based upon our investment strategy for the particular type of security and our cash flow needs, liquidity position, capital adequacy and interest rate risk position. 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. All debt securities, with the exception of one having a fair value of $0.4 million at September 30, 2019, were A-rated or better at the time of purchase and remained investment grade at September 30, 2019. All securities were evaluated for OTTI at September 30, 2019 and December 31, 2018. The result of this evaluation showed no OTTI as of September 30, 2019 or December 31, 2018. The estimated weighted average duration of MBS was 2.9 years at September 30, 2019.

ALLOWANCE FOR LOAN AND LEASE LOSSES AND CREDIT QUALITY INFORMATION	8. ALLOWANCE FOR LOAN AND LEASE LOSSES AND CREDIT QUALITY INFORMATION Allowance for Loan Losses We maintain an allowance for loan losses which represents our best estimate of probable losses in our loan portfolio. As losses are realized, they are charged to this allowance. We established our allowance in accordance with guidance provided in the SEC’s Staff Accounting Bulletin 102 (SAB 102), Selected Loan Loss Allowance Methodology and Documentation Issues, ASC 450, Contingencies and ASC 310, Receivables . When we have reason to believe it is probable that we will not be able to collect all contractually due amounts of principal and interest, loans are evaluated for impairment on an individual basis and a specific allocation of the allowance is assigned in accordance with ASC 310-10. We also maintain an allowance for loan losses on acquired loans: (i) for loans accounted for under ASC 310-20, the inherent losses in the loans exceed the remaining credit discount recorded at the time of acquisition and (ii) for loans accounted for under ASC 310-30, there is deterioration in credit quality subsequent to acquisition. The determination of the allowance for loan losses requires significant judgment reflecting our best estimate of impairment related to specifically identified impaired loans as well as probable loan losses in the remaining loan portfolio. Our evaluation is based on a continuous review of these portfolios. The following are included in our allowance for loan losses: • Specific reserves for impaired loans • An allowance for each pool of homogeneous loans based on historical loss experience • Adjustments for qualitative and environmental factors allocated to pools of homogeneous loans When it is probable that the Bank will be unable to collect all amounts due (interest and principal) in accordance with the contractual terms of the loan agreement, it assigns a specific reserve to that loan, as necessary. Unless loans are well-secured and collection is imminent, loans greater than 90 days past due are deemed impaired and their respective reserves are generally charged off once the loss has been confirmed. Estimated specific reserves are based on collateral values, estimates of future cash flows or market valuations. Loans are charged off when they are deemed to be uncollectible. During the nine months ended September 30, 2019 and 2018, net charge-offs totaled $15.8 million, or 0.27%, of average loans annualized, and $8.7 million, or 0.24%, of average loans annualized, respectively. Allowance for pooled homogeneous loans, that are not deemed impaired, are based on historical net loss experience. Estimated losses for pooled portfolios are determined differently for commercial and retail loan pools. Commercial loans are pooled as follows: commercial, owner-occupied commercial, commercial mortgages and construction. Each pool is further segmented by internally assessed risk ratings. Loan losses for commercial loans are estimated by determining the probability of default and expected loss severity upon default. The probability of default is calculated based on the historical rate of migration to impaired status during the last 35 quarters. During the nine months ended September 30, 2019, we increased the look-back period to 35 quarters from 32 quarters used at December 31, 2018. This increase in the look-back period allows us to continue to anchor to the fourth quarter of 2010 to ensure that the quantitative reserves calculated by the allowance for loan loss model are adequately considering the losses within a full credit cycle. Loss severity upon default is calculated as the actual loan losses (net of recoveries) on impaired loans in their respective pool during the same time frame. Retail loans are pooled into the following segments: residential mortgage, consumer secured and consumer unsecured loans. Pooled reserves for retail loans are calculated based solely on average net loss rates over the same 35 quarter look-back period. Qualitative adjustment factors consider various current internal and external conditions which are allocated among loan types and take into consideration: • Current underwriting policies, staff, and portfolio mix, • Internal trends of delinquency, nonaccrual and criticized loans by segment, • Risk rating accuracy, control and regulatory assessments/environment, • General economic conditions - locally and nationally, • Market trends impacting collateral values, and • Competitive environment, as it could impact loan structure and underwriting. The above factors are based on their relative standing compared to the period in which historic losses are used in quantitative reserve estimates and current directional trends. Qualitative factors in our model can add to or subtract from quantitative reserves. The allowance methodology uses a loss emergence period (LEP), which is the period of time between an event that triggers the probability of a loss and the confirmation of the loss. We estimate the commercial LEP to be approximately 8.89 quarters as of September 30, 2019. Our residential mortgage and consumer LEP estimate remains at four quarters as of September 30, 2019. We evaluate LEP quarterly for reasonableness and complete a detailed historical analysis of our LEP annually for our commercial portfolio and review the current four quarter LEP for the retail portfolio to determine the continued reasonableness of this assumption. 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 loan losses and the Bank’s internal loan review department performs loan reviews.

(2) The difference between this amount and nonaccruing loans represents accruing troubled debt restructured loans of $15.2 million for the period ending September 30, 2018. Accruing troubled debt restructured loans are considered impaired loans. (3) Ending loan balances do not include net deferred fees. Nonaccrual and Past Due Loans Nonaccruing loans are those on which the accrual of interest has ceased. Typically, we discontinue accrual of interest on originated loans after payments become more than 90 days past due or earlier if we do not expect the full collection of principal or interest in accordance with the terms of the loan agreement. 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 accretion of net deferred loan fees and amortization of net deferred loan costs 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 our assessment of the ultimate collectability of principal and interest. Loans greater than 90 days past due and still accruing are defined as loans contractually past due 90 days or more as to principal or interest payments, but which remain in accrual status because they are considered well secured and are in the process of collection.

Impaired Loans Loans for which it is probable we will not collect all principal and interest due according to their contractual terms, assessed based on the credit characteristics of the loan and/or payment status, are measured for impairment in accordance with the provisions of SAB 102 and ASC 310. The amount of impairment is required to be measured using one of three methods: (1) the present value of expected future cash flows discounted at the loan’s effective interest rate; (2) the fair value of the collateral if the loan is collateral dependent or (3) the loan’s observable market price. If the measure of the impaired loan is less than the recorded investment in the loan, a related allowance is allocated for the impairment. The following tables provide an analysis of our impaired loans at September 30, 2019 and December 31, 2018: September 30, 2019 (Dollars in thousands) Ending Loans with No Related Reserve (1) Loans with Related Reserve (2) Related Reserve Contractual Principal Balances (2) Average Loan Balances Commercial and industrial $ 21,138 $ 8,666 $ 12,472 $ 3,534 $ 25,423 $ 18,695 Owner-occupied commercial 10,559 9,107 1,452 235 10,913 7,650 Commercial mortgages 3,130 2,325 805 47 7,381 5,251 Construction 487 — 487 8 561 2,226 Residential 12,214 8,320 3,894 517 14,391 11,546 Consumer 7,531 6,198 1,333 182 8,262 7,870 Total $ 55,059 $ 34,616 $ 20,443 $ 4,523 $ 66,931 $ 53,238 (1) Reflects loan balances at or written down to their remaining book balance.

Interest income of $0.2 million and $0.6 million was recognized on impaired loans during the three and nine months ended September 30, 2019, respectively. Interest income of $0.6 million and $1.3 million was recognized on impaired loans during the three and nine months ended September 30, 2018, respectively. As of September 30, 2019, there were 40 residential loans and 32 commercial loans in the process of foreclosure. The total outstanding balance on these loans was $4.2 million and $11.3 million, respectively. As of December 31, 2018, there were 26 residential loans and 11 commercial loans in the process of foreclosure. The total outstanding balance on these loans was $1.9 million and $5.3 million, respectively. Reserves on Acquired Nonimpaired Loans In accordance with ASC 310, loans acquired by the Bank through its mergers with First National Bank of Wyoming, Alliance Bancorp, Inc. (Alliance), Penn Liberty Bank (Penn Liberty) and Beneficial are reflected on the balance sheet at their fair values on the date of acquisition as opposed to their contractual values. Therefore, on the date of acquisition establishing an allowance for acquired loans is prohibited. After the acquisition date, the Bank performs a separate allowance analysis on a quarterly basis to determine if an allowance for loan loss is necessary. Should the credit risk calculated exceed the purchased loan portfolio’s remaining credit mark, additional reserves will be added to the Bank’s allowance. When a purchased loan becomes impaired after its acquisition, it is evaluated as part of the Bank’s reserve analysis and a specific reserve is established to be included in the Bank’s allowance. 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 . 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. • Doubtful . Borrowers have well-defined weaknesses inherent in the Substandard category with 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. A doubtful asset has some pending event that may strengthen the asset that defers the loss classification. Such impending events include: perfecting liens on additional collateral, obtaining collateral valuations, an acquisition or liquidation preceding, proposed merger, or refinancing plan. • Loss . Loans are uncollectible or of such negligible value that continuance as a bankable asset is not supportable. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather it is not practical to defer writing off this asset even though partial recovery may be recognized sometime in the future. Residential and Consumer Loans The residential and consumer loan portfolios are monitored on an ongoing basis using delinquency information and loan type as credit quality indicators. These credit quality indicators are assessed in the aggregate in these relatively homogeneous portfolios. Loans that are greater than 90 days past due are generally considered nonperforming and placed on nonaccrual status. The following tables provide an analysis of loans by portfolio segment based on the credit quality indicators used to determine the Allowance for Loan Loss.

During the nine months ended September 30, 2019, we did not identify any indicators of impairment as it relates to goodwill or intangibles. The following table shows the allocation of goodwill to our reportable operating segments for purposes of goodwill impairment testing: (Dollars in thousands) WSFS Cash Wealth Consolidated December 31, 2018 $ 145,808 $ — $ 20,199 $ 166,007 Goodwill from business combinations 309,486 — — 309,486 Remeasurement period adjustments (2,535) — — (2,535) September 30, 2019 $ 452,759 $ — $ 20,199 $ 472,958 ASC 350 requires that an acquired intangible asset be separately recognized if the benefit of the intangible asset is obtained through contractual or other legal rights, or if the asset can be sold, transferred, licensed, rented or exchanged, regardless of the acquirer’s intent to do so.

Postemployment Benefits [Abstract]
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 net periodic benefit cost in Salaries, benefits and other compensation 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 measured at January 1, 2019 and 2018.

The Company currently anticipates completing the pension plan termination during the first quarter of 2020. As of September 30, 2019, the valuation of the benefit obligations and estimated future benefit payments did not include termination assumptions. 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.

Income Tax Disclosure [Abstract]
INCOME TAXES	13. INCOME TAXES We account for income taxes in accordance with ASC 740, Income Taxes (ASC 740). 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 September 30, 2019. We record interest and penalties on potential income tax deficiencies as income tax expense. Our federal and state tax returns for the 2016 through 2018 tax years are subject to examination as of September 30, 2019. We do not expect to record or realize any material unrecognized tax benefits during 2019. 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, $0.9 million and $0.5 million of such amortization has been reflected as income tax expense for the three months ended September 30, 2019 and 2018, respectively, and $2.1 million and $1.4 million of such amortization has been reflected as income tax expense for the nine months ended September 30, 2019 and 2018, respectively . The amount of affordable housing tax credits, amortization and tax benefits recorded as income tax expense for the nine months ended September 30, 2019 were $1.9 million, $2.1 million and $0.5 million, respectively. The carrying value of the investment in affordable housing credits is $26.7 million at September 30, 2019, compared to $16.9 million at December 31, 2018.

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 September 30, 2019 and December 31, 2018 by level in the valuation hierarchy (as described above): September 30, 2019 (Dollars in thousands) Quoted Significant Significant Total Fair Assets measured at fair value on a recurring basis: Available-for-sale securities: CMO $ — $ 365,246 $ — $ 365,246 FNMA MBS — 1,162,747 — 1,162,747 FHLMC MBS — 346,755 — 346,755 GNMA MBS — 34,073 — 34,073 Other assets — 6,540 — 6,540 Total assets measured at fair value on a recurring basis $ — $ 1,915,361 $ — $ 1,915,361 Liabilities measured at fair value on a recurring basis: Other liabilities $ — $ 5,974 $ — $ 5,974 Assets measured at fair value on a nonrecurring basis: Other investments $ — $ — $ 70,055 $ 70,055 Other real estate owned — — 3,693 3,693 Loans held for sale — 67,428 — 67,428 Impaired loans, net — — 50,536 50,536 Total assets measured at fair value on a nonrecurring basis $ — $ 67,428 $ 124,284 $ 191,712 December 31, 2018 (Dollars in thousands) Quoted Significant Significant Total Fair Assets measured at fair value on a recurring basis: Available-for-sale securities: CMO $ — $ 371,750 $ — $ 371,750 FNMA MBS — 644,073 — 644,073 FHLMC MBS — 153,922 — 153,922 GNMA MBS — 35,334 — 35,334 Other assets — 2,098 — 2,098 Total assets measured at fair value on a recurring basis $ — $ 1,207,177 $ — $ 1,207,177 Liabilities measured at fair value on a recurring basis: Other liabilities $ — $ 3,493 $ — $ 3,493 Assets measured at fair value on a nonrecurring basis Other investments — — 37,233 37,233 Other real estate owned — — 2,668 2,668 Loans held for sale — 25,318 — 25,318 Impaired loans, net — — 47,094 47,094 Total assets measured at fair value on a nonrecurring basis $ — $ 25,318 $ 86,995 $ 112,313 There were no transfers between Level 1 and Level 2 of the fair value hierarchy during the nine months ended September 30, 2019. 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 As of September 30, 2019, securities classified as available-for-sale are reported at fair value using Level 2 inputs. Included in the Level 2 total are $1.9 billion in Federal Agency MBS. We believe that this Level 2 designation is appropriate for these securities under ASC 820-10 because, as 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, among others, our Visa Class B shares and our investments in Spring EQ and SoFi, 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. As a result of our adoption of ASU 2016-01 and observable market transactions, we recorded unrealized gains on our investments in Visa Class B shares and Spring EQ of $26.2 million during the nine months ended September 30, 2019 as compared to $18.6 million during the nine months ended September 30, 2018. 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. Impaired loans We evaluate and value impaired loans at the time the loan is identified as impaired, and the fair values of such loans are estimated using Level 3 inputs in the fair value hierarchy. Each loan’s collateral has a unique appraisal and management’s discount of the value is based on the factors unique to each impaired loan. The significant unobservable input in determining the fair value is management’s subjective discount on appraisals of the collateral securing the loan, which typically ranges from 10% - 20%. Collateral may consist of real estate and/or business assets including equipment, inventory and/or accounts receivable and the value of these assets is determined based on the appraisals by qualified licensed appraisers hired by us. Appraised and reported values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, estimated costs to sell, and/or management’s expertise and knowledge of the client and the client’s business. The gross amount of impaired loans, which are measured for impairment by either calculating the expected future cash flows discounted at the loan’s effective interest rate or determining the fair value of the collateral for collateral dependent loans was $55.0 million and $49.4 million at September 30, 2019 and December 31, 2018, respectively. The valuation allowance on impaired loans was $4.5 million as of September 30, 2019 and $2.3 million as of December 31, 2018. 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 utilize 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 type: commercial, commercial small business leases, commercial mortgages, owner-occupied commercial, construction, residential mortgages and consumer. 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. 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 includes, among other things, investments in subsidiaries, prepaid expenses, interest and fee income receivable, derivative financial instruments and deferred tax assets (see discussion in “Fair Value of Financial Assets and Liabilities” section above). Deposits The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, money market and interest-bearing demand deposits, is assumed to be equal to the amount payable on demand. The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using rates currently offered for deposits with comparable remaining maturities. Borrowed funds Rates currently available to us for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt. Other liabilities Other liabilities includes, among others, cash flow derivatives and derivatives on the residential mortgage held for sale pipeline. Valuation of our cash flow derivatives 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 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. The book value and estimated fair value of our financial instruments are as follows: September 30, 2019 December 31, 2018 (Dollars in thousands) Fair Value Book Value Fair Value Book Value Fair Value Financial assets: Cash and cash equivalents Level 1 $ 580,299 $ 580,299 $ 620,757 $ 620,757 Investment securities available for sale See previous table 1,908,821 1,908,821 1,205,079 1,205,079 Investment securities held to maturity Level 2 134,961 138,262 149,950 149,431 Other investments Level 3 70,055 70,055 37,233 37,233 Loans, held for sale Level 2 67,428 67,428 25,318 25,318 Loans, net (1)(2) Level 3 8,430,176 8,530,619 4,816,825 4,772,377 Impaired loans, net Level 3 50,536 50,536 47,094 47,094 Stock in FHLB of Pittsburgh Level 2 22,630 22,630 19,259 19,259 Accrued interest receivable Level 2 38,771 38,771 22,001 22,001 Other assets Level 2 6,540 6,540 2,098 2,098 Financial liabilities: Deposits Level 2 9,533,193 9,835,611 5,640,431 5,597,227 Borrowed funds Level 2 554,783 555,555 699,788 694,526 Standby letters of credit Level 3 461 461 495 495 Accrued interest payable Level 2 9,481 9,481 1,900 1,900 Other liabilities Level 2 5,974 5,974 3,493 3,493 (1) Excludes impaired loans, net.

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 September 30, 2019. Fair Values of Derivative Instruments (Dollars in thousands) Count Notional Balance Sheet Location Derivatives Derivatives designated as hedging instruments: Interest rate products 3 $ 75,000 Other liabilities $ (591) Total $ 75,000 $ (591) Derivatives not designated as hedging instruments: Interest rate products $ 80,405 Other assets $ 4,085 Interest rate products 80,405 Other liabilities (5,029) Risk participation agreements 5,402 Other liabilities (10) Interest rate lock commitments with customers 117,744 Other assets 1,940 Interest rate lock commitments with customers 23,043 Other liabilities (130) Forward sale commitments 66,979 Other assets 515 Forward sale commitments 76,733 Other liabilities (214) Total $ 450,711 $ 1,157 Total derivatives $ 525,711 $ 566 The table below presents the fair value of our derivative financial instruments as well as their location on the Consolidated Statements of Financial Condition as of December 31, 2018.

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 nine months ended September 30, 2019, 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 $0.4 million will be reclassified as an increase to interest income. During the nine months ended September 30, 2019, $1.1 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 September 30, 2019, we had three outstanding interest rate derivatives with an aggregate notional amount of $75 million that were designated as cash flow hedges of interest rate risk.

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 within 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 (doing business as WSFS Institutional Services) provides trustee, agency, bankruptcy administration, custodial and commercial domicile services to institutional and corporate clients. The personal trust division of WSFS (doing business as 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.

INDEMNIFICATIONS AND GUARANTEES	17. INDEMNIFICATIONS AND GUARANTEES 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 was one repurchase for $0.2 million during the nine months ended September 30, 2019. Swap Guarantees We entered into agreements with five unrelated financial institutions whereby those financial institutions entered into interest rate derivative contracts (interest rate swap transactions) 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 in the event that the customer defaults on the swap agreement and the agreement is in a paying position to the third-party financial institution. This is a customary arrangement that allows us to provide access to interest rate swap transactions for our customers without creating the swap ourselves. These swap guarantees are accounted for as credit derivatives . At September 30, 2019 and December 31, 2018, there were 158 and 136 variable-rate to fixed-rate swap transactions between the third party financial institutions and our customers, respectively. The initial notional aggregate amount was approximately $769.4 million at September 30, 2019 compared to $581.5 million at December 31, 2018. At September 30, 2019, maturities ranged from under 1 year to 15 years. The aggregate market value of these swaps to the customers was a liability of $33.7 million at September 30, 2019 and a liability of $0.3 million at December 31, 2018. At September 30, 2019, 147 swaps, with a liability of $34.7 million, were in paying positions to a third party. We had no reserves for these swap guarantees as of September 30, 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 and nine months ended September 30, 2019 there were one and two loans, respectively, 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. The case is currently scheduled to go to trial during the first quarter of 2020. 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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) and Christiana Trust Company of Delaware (Christiana Trust DE). We also have one unconsolidated subsidiary, WSFS Capital Trust III. WSFS Bank has four wholly owned subsidiaries: Beneficial Equipment Finance Corporation (BEFC), WSFS Investment Group, Inc. (WSFS Wealth Investments), 1832 Holdings, Inc., and WSFS SPE Services, LLC, 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 127 offices located in Pennsylvania (56) , Delaware (49), New Jersey (20), Virginia (1) and Nevada (1) and through our website at www.wsfsbank.com . 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 (formerly Neumann Finance Company). 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 loan and lease losses and reserves for lending-related commitments, goodwill, intangible assets, post-retirement benefit obligations, the fair value of financial instruments, income taxes and other-than-temporary impairment (OTTI). Among other effects, changes to these estimates could result in future impairments of investment securities, goodwill and intangible assets, the establishment of the allowance and lending-related commitments 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, 2019. 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, 2018 (the 2018 Annual Report on Form 10-K) that was filed with the SEC on February 28, 2019 and is available at www.sec.gov or on our website at www.wsfsbank.com . All significant intercompany transactions were eliminated in consolidation.
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Accounting Guidance Adopted in 2019 ASU No. 2016-02, Leases (Topic 842): In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . This ASU revises lessee accounting. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for substantially all leases. The new lease guidance also simplifies the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. ASU 2016-02 is effective for the first interim period within annual periods beginning after December 15, 2018, with early adoption permitted. Adoption using the comparative modified retrospective transition approach is required; however, in July 2018, the FASB issued ASU 2018-11, Leases-Targeted Improvements , which provides an optional transition method whereby comparative periods presented in the financial statements in the period of adoption do not need to be restated under Topic 842. The Company adopted this guidance and its related amendments on January 1, 2019 using the transition option in ASU 2018-11 and the results of this adoption are recorded in the Consolidated Statements of Financial Condition. See Note 9 for additional disclosures resulting from our adoption of this standard. ASU No. 2019-01, Leases (Topic 842), Codification Improvements: Subsequent to adopting ASU 2016-02, in March 2019, the FASB issued ASU No. 2019-01, Leases (Topic 842) : Codification Improvements , which makes targeted changes to lessor accounting and clarifies interim transition disclosure requirements upon adopting Topic 842. The guidance is effective for annual periods beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. The Company adopted this guidance on March 31, 2019. See Note 9 for additional disclosures resulting from our adoption of this standard. ASU No. 2017-08, Premium Amortization on Purchased Callable Debt Securities: In March 2017, the FASB issued ASU No. 2017-08, Premium Amortization on Purchased Callable Debt Securities . The new guidance requires the amortization period for certain non-contingent callable debt securities held at a premium to end at the earliest call date of the debt security. If the call option is not exercised at the earliest call date, the guidance requires the debt security's effective yield to be reset based on the contractual payment terms of the debt security. The guidance is effective in annual and interim periods in fiscal years beginning after December 15, 2018. Early adoption is permitted. Use of the modified retrospective method, with a cumulative-effect adjustment to retained earnings is required. The Company adopted this standard on January 1, 2019, on a modified retrospective basis and the adoption did not have an effect on the Consolidated Financial Statements. ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities (Topic 815): In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities (Topic 815) . The new guidance changes both the designation and measurement guidance for qualifying hedging relationships and simplifies the presentation of hedge results. Specifically, the guidance eliminates the requirement to separately measure and report hedge ineffectiveness and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. Further, the new guidance provides entities the ability to apply hedge accounting to additional hedging strategies as well as permits a one-time reclassification of eligible to be hedged instruments from held to maturity to available for sale upon adoption. The guidance is effective in annual and interim periods beginning after December 15, 2018. Early adoption is permitted. Adoption using the modified retrospective approach is required for hedging relationships that exist as of the date of adoption; presentation and disclosure requirements are applied prospectively. The Company adopted this standard on January 1, 2019, on a modified retrospective basis for existing hedging relationships and on a prospective basis for presentation and disclosure requirements. The adoption of this standard did not have an effect on the Consolidated Financial Statements. See Note 15 for additional disclosures resulting from our adoption of this standard. ASU No. 2018-16, Derivatives and Hedging - Inclusion of the Secured Overnight Financial Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes (Topic 815): In October 2018, the FASB issued ASU No. 2018-16, Derivatives and Hedging - Inclusion of the Secured Overnight Financial Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes (Topic 815) . The new guidance applies to all entities that elect to apply hedge accounting to benchmark interest rate hedges under Topic 815. It permits the use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes in addition to the existing applicable rates. The guidance is required to be adopted concurrently with ASU 2017-12, on a prospective basis for qualifying new or redesignated hedging relationships entered into on or after adoption. The Company adopted this standard on January 1, 2019 on a prospective basis and the adoption did not have an effect on the Consolidated Financial Statements. Accounting Guidance Pending Adoption at September 30, 2019 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 and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses. Purchased credit impaired assets will receive an allowance account at the acquisition date that represents a component of the purchase price allocation. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses, with such allowance limited to the amount by which fair value is below amortized cost. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326 , which clarifies that receivables arising from operating leases are not within the scope of Topic 326. In December 2018, regulators issued a final rule related to regulatory capital ( 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 ) which is intended to provide regulatory capital relief to entities transitioning to CECL. In May 2019, the FASB issued ASU No. 2019-05, Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief , which provides entities the option to irrevocably elect the fair value option on financial instruments within the scope of both ASC 326-20 and ASC 825-10 upon adoption of ASU 2016-13. This guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The Company will adopt this guidance on January 1, 2020. The adoption of this guidance will affect our accounting for loans, leases, purchased financial assets, debt securities, and unfunded commitments. A cross-functional team from Finance, Credit, and Information Technology is leading the implementation efforts, and continue to assess the impact of this guidance on the Company’s Consolidated Financial Statements, internal systems, accounting policies, processes and related internal controls. We have completed the implementation of our software solution and a third-party specialist has completed an independent model review of the solution. Further, we have defined our loan portfolio categories, credit loss methodologies, reasonable and supportable forecast and reversion periods. Our implementation efforts continue to focus on our comprehensive evaluation of model outputs based on the implementation decisions made to date, as well as defining the framework and evaluating the impact of qualitative adjustment factors, and refining our allowance for credit losses (ACL) governance framework. We are in the process of finalizing our accounting policies and reporting requirements under the guidance as well as implementation and transition rules issued by regulators. As necessary, we will continue to consult with third-party experts and specialists to assist with our adoption efforts. Our implementation efforts to date suggest that adoption may materially increase the allowance for credit losses and decrease capital levels; however, the extent of these impacts will depend on the composition and asset quality of the portfolio, macroeconomic conditions, and continued refinement of significant estimates and judgments by management at the time of adoption. 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 does not expect the application of this guidance to have a material impact on the Consolidated Financial Statements. 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 does not expect the application of this guidance to have a material impact on the Consolidated Financial Statements. 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. Our preliminary review of this guidance to date suggests that adoption may result in a material amount of implementation costs being deferred; however, the extent of the impact will depend on the cloud computing implementations occurring 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 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 will evaluate the amendments to ASU 2016-13 in conjunction with our overall evaluation of ASU 2016-13. For other amendments within this guidance, the Company does not expect the application of this guidance to have a material impact on the Consolidated Financial Statements.
