Summary of Significant Accounting Policies

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

WSFS Financial Corporation (the Company, our Company, WSFS, we, our or us) is a savings and loan holding company organized under the laws of the State of Delaware. Our principal wholly-owned subsidiary, Wilmington Savings Fund Society, FSB (WSFS Bank or the Bank), is a federal savings bank organized under the laws of the United States which, at December 31, 2014, served customers from our 55 offices located in Delaware (45), Pennsylvania (8), Virginia (1), and Nevada (1).

In preparing the Consolidated Financial Statements, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Although our estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions in 2015 could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition. Amounts subject to significant estimates are items such as the allowance for loan losses and lending-related commitments, goodwill and intangible assets, post-retirement obligations, the fair value of financial instruments, investment in reverse mortgage, income taxes and other-than-temporary impairments. Among other effects, such changes could result in future impairments of investment securities, goodwill and intangible assets and establishment of an allowance for loan losses and lending-related commitments as well as increased post-retirement expense.

Basis of Presentation

The Consolidated Financial Statements include the accounts of the parent company and its wholly-owned subsidiaries, WSFS Bank and Cypress Capital Management, LLC (Cypress).

WSFS Bank has two wholly-owned subsidiaries, including WSFS Wealth Investments and Monarch Entity Services LLC (Monarch). WSFS Wealth Investments markets various third-party insurance and securities products to Bank customers through the Bank’s retail banking system. Monarch provides commercial domicile services which include employees, directors, subleases and registered agent services in Delaware and Nevada.

Cypress was formed to provide asset management products and services. As a Wilmington-based investment advisory firm servicing high net worth individuals and institutions, it has approximately $661 million in assets under management at December 31, 2014, compared to approximately $614 million at December 31, 2013.

WSFS Capital Trust III (the Trust) is our unconsolidated subsidiary, and was formed in 2005 to issue $67.0 million aggregate principal amount of Pooled Floating Rate Capital Securities. The proceeds from this issue were used to fund the redemption of $51.5 million of Floating Rate WSFS Capital Trust I Preferred Securities (formerly, WSFS Capital Trust I). WSFS Capital Trust I invested all of the proceeds from the sale of the Pooled Floating Rate Capital Securities in our Junior Subordinated Debentures.

In addition to the subsidiaries listed above, as of December 31, 2013 the Company also had one consolidated variable interest entity (VIE), SASCO 2002-RM1 (SASCO), which is a reverse mortgage securitization trust. This entity was combined with WSFS Bank in 2014.

Whenever necessary, reclassifications have been made to the prior years’ Consolidated Financial Statements to conform to the current year’s presentation. All significant intercompany transactions were eliminated in consolidation.

Cash and Cash Equivalents

For purposes of reporting cash flows, cash and cash equivalents include cash, cash in non-owned ATMs, amounts due from banks, federal funds sold and securities purchased under agreements to resell.

Debt and Equity Securities

Investments in equity securities that have a readily determinable fair value and investments in debt securities are classified into three categories and accounted for as follows:

•

Debt securities with the positive intention to hold to maturity are classified as “held-to-maturity” and reported at amortized cost.

•

Debt and equity securities purchased with the intention of selling them in the near future are classified as “trading securities” and reported at fair value, with unrealized gains and losses included in earnings.

•

Debt and equity securities not classified in either of the above are classified as “available-for-sale securities” and reported at fair value, with unrealized gains and losses excluded from earnings and reported, net of tax, as a separate component of stockholders’ equity.

Debt and equity securities include mortgage-backed securities (MBS), municipal bonds, U.S. Government and agency securities and certain equity securities. Premiums and discounts on debt and equity securities, held-to-maturity and available-for-sale, are recognized in interest income using a level yield method over the period to expected maturity. The fair value of debt and equity securities is primarily obtained from third-party pricing services. Implicit in the valuation are estimated prepayments based on historical and current market conditions.

When we conclude an investment security is other-than-temporarily impaired (OTTI), a loss for the difference between the investment security’s carrying value and its fair value may be recognized as a reduction to non-interest income in the Consolidated Statements of Operations. For an investment in a debt security, if we intend to sell the investment security or it is more likely than not that we will be required to sell it before recovery, an OTTI write-down is recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value. If we do not intend to sell the investment security and conclude that it is not more likely than not we will be required to sell the security before recovering the carrying value, which may be maturity, the OTTI charge is separated into “credit” and “other” components. The “other” component of the OTTI is included in other comprehensive income/loss, net of the tax effect, and the “credit” component of the OTTI is included as a reduction to non-interest income in the Consolidated Statements of Operations. We are required to use our judgment to determine impairment in certain circumstances. The specific identification method is used to determine realized gains and losses on sales of investment and mortgage-backed securities. All sales are made without recourse.

Reverse Mortgage Loans

We account for our investment in reverse mortgages in accordance with the instructions provided by the staff of the Securities and Exchange Commission (SEC) entitled “Accounting for Pools of Uninsured Residential Reverse Mortgage Contracts,” which requires grouping the individual reverse mortgages into “pools” based on similar characteristics and recognizing income based on the estimated effective yield of the pools. In computing the effective yield, we must project the cash inflows and outflows of the pool including actuarial projections of the life expectancy of the individual contract holder and changes in the collateral value of the residence. At each reporting date, a new economic forecast is made of the cash inflows and outflows of each pool of reverse mortgages. The effective yield of each pool is recomputed and income is adjusted to reflect the revised rate of return. Because of this highly specialized accounting, the recorded value of reverse mortgage assets can result in significant volatility associated with estimations. As a result, income recognition can vary significantly from reporting period to reporting period.

For additional detail regarding reverse mortgages, see Note 7 to the Consolidated Financial Statements.

Loans

Loans are stated net of deferred fees and costs. Interest income on loans is recognized using the level yield method. Loan origination fees, commitment fees and direct loan origination costs are deferred and recognized over the life of the related loans using a level yield method over the period to maturity.

A loan is impaired when, based on current information and events, it is probable we will be unable to collect all amounts due according to the contractual terms of the loan agreement. Impaired loans are measured based on the present value of expected future discounted cash flows, the market price of the loan or the fair value of the underlying collateral if the loan is collateral dependent. In addition, all loans restructured in a troubled debt restructuring are considered to be impaired. Impaired loans include loans within our commercial (investor and owner-occupied), commercial mortgage, commercial construction, residential mortgages and consumer portfolios. Our policy for recognition of interest income on impaired loans, excluding accruing loans, is the same as for nonaccrual loans discussed below.

In addition to originating loans, we occasionally acquire loans through mergers or loan purchase transactions. Some of these acquired loans may exhibit deteriorated credit quality that has occurred since origination and we may not expect to collect all contractual payments. Accounting for these purchased credit-impaired loans is done in accordance with ASC 310-30. The loans are initially recorded at fair value on the acquisition date, reflecting the present value of the amounts expected to be collected. Income recognition on these loans is based on a reasonable expectation about the timing and amount of cash flows to be collected. Acquired loans are evaluated for impairment on a quarterly basis with complete updating of the estimated cash flows on a semi-annual basis, and if a loan is determined to be impaired but considered collateral dependent, it will have no accretable yield.

Past Due and Nonaccrual Loans

A loan is considered to be past due on the day after a principal or interest payment is due. Nonaccrual loans are those on which the accrual of interest has ceased. Loans are placed on nonaccrual status immediately if, in our opinion, collection is doubtful, or when principal or interest is contractually past due 90 days or more and the loan is not well secured or in the process of collection. Interest accrued but not collected at the date a loan is placed on nonaccrual status is reversed and charged against interest income. In addition, the accretion of net deferred loan fees is suspended when a loan is placed on nonaccrual status. Subsequent cash receipts are applied either to the outstanding principal or recorded as interest income, depending on our assessment of the ultimate collectability of the loan. Loans are returned to an accrual status when we assess that the borrower has the ability to make all principal and interest payments in accordance with the terms of the loan (i.e. including a consistent repayment record, generally six consecutive payments, has been demonstrated).

Allowance for Loan Losses

We maintain an allowance for loan losses and charge losses to this allowance when such losses are realized. The determination of the allowance for loan losses requires significant judgment reflecting our best estimate of impairment related to specifically identified loans as well as probable loan losses in the remaining loan portfolio. Our evaluation is based upon a continuing review of these portfolios.

We have established the loan loss allowance in accordance with guidance provided by the SEC’s Staff Accounting Bulletin 102 (SAB 102). Our methodology for assessing the appropriateness of the allowance consists of several key elements which include: a specific allowance for identified impaired loans, an allowance for pools of homogeneous loans, adjustments for qualitative and environmental factors and an allowance for model estimation and complexity risk. Impairment of troubled debt restructurings are measured at the present value of estimated future cash flows using the loan’s effective rate at inception or the fair value of the underlying collateral if the loan is collateral dependent. Troubled debt restructures consist of concessions granted to borrowers facing financial difficulty. For additional detail regarding the provision for loan losses, see Note 6 to the Consolidated Financial Statements.

Loans Held-for-Sale

Loans held-for-sale are carried at their fair value on a loan level.

Assets Acquired Through Foreclosure

Assets acquired through foreclosure are recorded at the lower of the recorded investment in the loans or their fair value less estimated disposal costs. Costs subsequently incurred to improve the assets are included in the carrying value provided that the resultant carrying value does not exceed fair value less estimated disposal costs. Costs relating to holding or disposing of the assets are charged to expense in the current period. We write-down the value of the assets when declines in fair value below the carrying value are identified. Loan workout and OREO expenses include costs of holding and operating the assets, net gains or losses on sales of the assets and provisions for losses to reduce such assets to fair value less estimated disposal costs. During 2014, we recorded $672,000 in charges (including write-downs and net losses on sales of assets) related to assets acquired through foreclosure (REO). These charges were $592,000 and $4.3 million for the years ended December 31, 2013 and 2012, respectively. As of December 31, 2014 we had $4.4 million in residential real estate in process of foreclosure.

Premises and Equipment

Premises and equipment is stated at cost less accumulated depreciation and amortization. Costs of major replacements, improvements and additions are capitalized. Depreciation expense is computed on a straight-line basis over the estimated useful lives of the assets or, for leasehold improvements, over the effective life of the related lease if less than the estimated useful life. In general, computer equipment, furniture and equipment and building renovations are depreciated over three, five and ten years, respectively.

Goodwill and Other Intangible Assets

In accordance with FASB ASC 805, Business Combinations, and FASB ASC 350, Intangibles—Goodwill and Other, all assets and liabilities acquired in purchase acquisitions, including goodwill, indefinite-lived intangibles and other intangibles are recorded at fair value. We consider our accounting policies related to goodwill and other intangible assets to be critical because the assumptions or judgment used in determining the fair value of assets and liabilities acquired in past acquisitions are subjective and complex. As a result, changes in these assumptions or judgment could have a significant impact on our financial condition or results of operations. For additional information regarding our goodwill and other intangible assets, see Notes 2 & 8 to the Consolidated Financial Statements.

Federal Funds Purchased and Securities Sold Under Agreements to Repurchase

We enter into sales of securities under agreements to repurchase. Securities sold under agreements to repurchase are treated as financings, with the obligation to repurchase securities sold reflected as a liability in the Consolidated Statement of Condition. The securities underlying the agreements are assets. Generally, federal funds are purchased for periods ranging up to 90 days.

Loss Contingency for Unfunded Commitments

We maintain a loss contingency accrual for probable losses related to unfunded commitments. The determination of the loss contingency for unfunded commitments requires significant judgment reflecting management’s best estimate of probable losses related to unfunded commitments.

Income Taxes

The provision for income taxes includes federal, state and local income taxes currently payable and those deferred because of temporary differences between the financial statement basis and tax basis of assets and liabilities.

We account for income taxes in accordance with Financial Accounting Standard Board (FASB) Accounting Standards Codification (ASC) 740, Income Taxes. ASC 740. It prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. Benefits from tax positions are recognized in the financial statements only when it is more-likely-than-not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. ASC 740 also provides guidance on the accounting for and disclosure of unrecognized tax benefits, interest and penalties.

RECENT ACCOUNTING PRONOUNCEMENTS

In July 2013, the FASB issued ASU No. 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists,” to clarify the balance sheet presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The ASU requires an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We have determined that the adoption does not materially effect our Consolidated Financial Statements.

In January 2014, the FASB issued ASU No. 2014-01, “Investments — Equity Method and Joint Ventures (Topic 323) — Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force).” The ASU permits an entity to make an accounting policy election to account for its investment in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportionate amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The decision to apply the proportionate amortization method of accounting should be applied consistently to all qualifying affordable housing project investments. A reporting entity that uses the effective yield or other method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply such method to those preexisting investments. The amendments are effective for annual and interim periods beginning after December 15, 2014. The Company does not expect the application of this guidance to have a material impact on the Company’s financial statements.

In January 2014, the FASB issued ASU No. 2014-04, “Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.” The objective of this guidance is to clarify when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. ASU No. 2014-04 states that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, ASU No. 2014-04 requires interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU No. 2014-04 is effective for interim and annual reporting periods beginning after December 15, 2014. The adoption of ASU No. 2014-04 is not expected to have a material impact on the Company’s Consolidated Financial Statements.

In April 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” This ASU includes amendments that change the requirements for reporting discontinued operations and disposals of components of an entity. Under the new guidance, only disposals representing a strategic shift that has (or will have) a major effect on the organization’s operations and financial results should be presented as discontinued operations. Additionally, the ASU requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. These amendments are effective prospectively for fiscal years and interim reporting periods within those years, beginning after December 15, 2014. The Company does not expect the application of this guidance to have a material impact on the Company’s financial statements.

In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, “Revenue from Contracts with Customers (Topic 606).” The ASU introduces a new five-step revenue recognition model in which an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. This standard is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The Company does not expect the application of this guidance to have a material impact on the Company’s financial statements.

In June 2014, the FASB issued ASU No. 2014-11, “Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.” The new guidance aligns the accounting for repurchase-to-maturity transactions and repurchase agreements executed as repurchase financings with the accounting for other typical repurchase agreements. Going forward, these transactions would all be accounted for as secured borrowings. The guidance eliminates sale accounting for repurchase-to-maturity transactions and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement, which has resulted in outcomes referred to as off-balance-sheet accounting. The amendments in the ASU require a new disclosure for transactions economically similar to repurchase agreements in which the transferor retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. The amendments in the ASU also require expanded disclosures about the nature of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. The amendments in this ASU are effective for public companies for the first interim or annual period beginning after December 15, 2014. In addition, for public companies, the disclosure for certain transactions accounted for as a sale is effective for the first interim or annual reporting periods beginning on or after December 15, 2014, and the disclosure for transactions accounted for as secured borrowings is required to be presented for annual reporting periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. The Company does not expect the application of this guidance to have a material impact on the Company’s financial statements.

In June 2014, the FASB issued ASU 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” The standard update resolves the diverse accounting treatment for these share-based payments by requiring that a performance target that affects vesting and that could be achieved after the requisite service period is treated as a performance condition. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. ASU 2014-12 will be effective for interim and annual reporting periods beginning after December 15, 2015. Early application is permitted. The Company does not expect the application of this guidance to have a material impact on the Company’s financial statements.

In August 2014, the FASB issued ASU No. 2014-14, “Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” The objective of this guidance is to reduce diversity in practice related to how creditors classify government-guaranteed mortgage loans, including FHA or VA guaranteed loans, upon foreclosure. Some creditors reclassify those loans to real estate consistent with other foreclosed loans that do not have guarantees; others reclassify the loans to other receivables. The amendments in this guidance require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) The loan has a government guarantee that is not separable from the loan before foreclosure; (2) At the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim; and (3) At the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. ASU No. 2014-14 is effective for interim and annual reporting periods beginning after December 15, 2014. The Company does not expect the application of this guidance to have a material impact on the Company’s financial statements.

Business Combinations [Abstract]
Business Combinations	2. BUSINESS COMBINATIONS
	First Wyoming Financial Corporation
	On September 5, 2014, the Company completed the merger of First Wyoming Financial Corporation (FNBW) into the Company and the merger of FNBW’s wholly-owned subsidiary, The First National Bank of Wyoming (First Wyoming) into the Bank. In accordance with the terms of the Agreement and Plan of Merger, dated November 25, 2013 holders of shares of FNBW common stock received, in aggregate, $32.0 million in cash and 452,661 shares of WSFS common stock. The transaction was valued at $64.9 million based on WSFS’ closing share price of $72.70 on the NASDAQ stock market as of September 5, 2014. This in-market combination significantly bolsters our presence in Kent County and strengthens our position as the leading independent community bank in Delaware. The results of the combined entity’s operations are included in our unaudited Consolidated Statements of Operations for the period beginning on September 5, 2014, the date of the acquisition.
	The acquisition of FNBW was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed and consideration paid were recorded at their estimated fair values as of the acquisition date. The excess of consideration paid over the preliminary fair value of net assets acquired was recorded as goodwill in the amount of $16.4 million, which will not be amortizable and is not deductible for tax purposes. The Company allocated the total balance of goodwill to its WSFS Bank segment. The Company also recorded $3.2 million in core deposit intangibles which will be amortized over ten years using an accelerated depreciation method.
	The fair values listed below are preliminary estimates and are subject to adjustment. While they are not expected to be materially different than those shown, any adjustments to the estimates will be reflected, retroactively, as of the date of the acquisition.

	In connection with the merger, the consideration paid and the fair value of identifiable assets acquired and liabilities assumed as of the date of acquisition are summarized in the following table:


	(In Thousands)		Fair Value
	Consideration Paid:
	Common shares issued (452,661)		$	32,908
	Cash paid to FNBW stockholders			32,028

	Value of consideration			64,936
	Assets acquired:
	Cash and due from banks			40,605
	Investment securities			41,822
	Loans			175,966
	Premises and equipment			1,644
	Deferred income taxes			3,139
	Bank owned life insurance			12,624
	Core deposit intangible			3,240
	Other Real Estate Owned			1,641
	Other assets			4,771

	Total assets			285,452
	Liabilities assumed:
	Deposits			228,844
	FHLB advances			5,052
	Other liabilities			2,990

	Total liabilities			236,886
	Net assets acquired:			48,566

	Goodwill resulting from acquisition of FNBW:		$	16,370

	The following table details the changes to goodwill:


			Fair Value
	Goodwill resulting from the acquisition of FNBW reported as of September 30, 2014		$	16,467
	Effects of adjustments to:
	Assets			(187	)
	Liabilities			99
	Final purchase price			(9	)

	Adjusted goodwill resulting from the acquisition of FNBW as of December 31, 2014		$	16,370

	In many cases, the fair values of assets acquired and liabilities assumed were determined by estimating the cash flows expected to result from those assets and liabilities and discounting them at appropriate market rates.
	Acquired loans were recorded at their fair value as of the acquisition date. The fair value was based on a discounted cash flow methodology that uses assumptions as to credit risk, default rates, collateral values, loss severity, along with estimated prepayment rates. Non-impaired acquired loans had a gross contractual balance of $163.7 million and a fair value of $158.7 million. Loans that had deteriorated in credit quality since their origination, and for which it was probable that all contractual cash flows would not be received, were accounted for in accordance with ASC 310-30 “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” The gross contractual balance of the impaired loans was $24.2 million with a fair value of $17.3 million. For additional information regarding acquired impaired loans, see Note 4 to the Consolidated Financial Statements.

	The Company acquired FNBW’s investment portfolio with a fair value of $41.8 million, of which $31.5 million were sold at acquisition. The fair value of the investment portfolio was determined by taking into account market prices obtained from independent valuation sources and subsequent sales. For additional information regarding level 2 valuation, see Note 18 to the Consolidated Financial Statements.
	The Company recorded a deferred income tax asset (DTA) of $3.1 million related to tax attributes of FNBW along with the effects of fair value adjustments resulting from acquisition accounting for the combination.
	The fair value of savings and transaction deposit accounts acquired was assumed to approximate their carrying value as these accounts have no stated maturity and are payable on demand. Certificates of deposit accounts were valued by comparing the contractual cost of the portfolio to an identical portfolio bearing current market rates. The portfolio was segregated into pools based on remaining maturity. For each pool, the projected cash flows from maturing certificates were then calculated based on contractual rates and prevailing market rates. The valuation adjustment for each pool is equal to the present value of the difference of these two cash flows, discounted at the assumed market rate for a certificate with a corresponding maturity. The valuation adjustment will be accreted or amortized to interest expense over the remaining maturities of the respective pools.
	The fair value of the FHLB advance was determined based on the prepayment penalties that would have been assessed as of September 5, 2014 by the FHLB for its redemption. The adjustment to the face value of the borrowing will be accreted to reduce interest expense over the remaining life of the advance.
	Direct costs related to the acquisition were expensed as incurred. During the twelve months ended December 31, 2014, the Company incurred $3.8 million in integration expenses, including $1.1 million in salary and benefits, $1.4 million in data processing expense, $690,000 in professional fees and $296,000 in marketing expense.
	Array Financial Group, Inc. and Arrow Land Transfer Company Acquisition
	On July 31, 2013, WSFS Bank completed the purchase of Array Financial Group, Inc. (Array), a Delaware Valley mortgage banking company, specializing in a variety of residential mortgage and refinancing solutions, and Arrow Land Transfer Company (Arrow), an abstract and title company that is a related entity to Array.
	These companies were acquired through an asset purchase transaction for the purchase price of $8.0 million (including a $1.4 million payment for the working capital of the two companies), $4.0 million of which can be earned through a five-year earn out based on achieved earnings contribution targets, the fair value of which is $2.2 million at December 31, 2014. Operating results of Array and Arrow are included in the Consolidated Financial Statements since the date of acquisition.
	The transaction was accounted for as a business combination using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed and consideration paid were recorded at their estimated fair values as of the acquisition date. The excess of consideration paid over the fair value of net assets acquired was recorded as goodwill, which will not be amortizable for book purposes, however will be deductible for tax purposes. We allocated the total balance of goodwill to our WSFS Bank segment. We also recognized $2.4 million in intangible assets which will be amortized over seven years utilizing the straight-line method.

	In connection with the merger, the consideration paid and the fair value of the assets acquired and the liabilities assumed as of the date of acquisition are summarized in the following table:


(In Thousands)		Fair Value
Consideration Paid:
Cash paid at closing		$	5,374
Fair value of contingent consideration			2,771

Value of consideration			8,145
Assets acquired:

-1	Actual maturities could differ from contractual maturities.
There were no held-to-maturity securities as of December 31, 2013.
MBS have expected maturities that differ from their contractual maturities. These differences arise because borrowers have the right to call or prepay obligations with or without a prepayment penalty.
Investment securities with fair market values aggregating $470.4 million, $447.7 million and $486.9 million were pledged as collateral for retail customer repurchase agreements, municipal deposits, and other obligations as of December 31, 2014, 2013 and 2012, respectively. From time to time, investment securities are also pledged as collateral for FHLB borrowings. There were no FHLB pledged investment securities at December 31, 2014, 2013 or 2012.
During 2014, we sold $227.7 million of investment securities categorized as available-for-sale for net gains of $1.0 million, of which $1.1 million was gain and $60,000 was losses. In 2013, we sold $274.1 million investment securities categorized as available-for-sale for net gains of $3.5 million, of which $3.7 million was gain and $230,000 was losses. The cost basis of all investment securities sales is based on the specific identification method.
As of December 31, 2014, our investment securities portfolio had remaining unamortized premiums of $22.4 million and $188,000 of unaccreted discounts.

All securities, with the exception of two, were AA-rated or better at the time of purchase and remained investment grade at December 31, 2014. In December 2014, we purchased a BBB- bond with a fair market value of $1.3 million as part of a financing transaction for an ongoing lending relationship. On September 5, 2014, we acquired one unrated municipal bond with a fair value of $179,000. All securities were evaluated for OTTI at December 31, 2014 and 2013. The result of this evaluation showed no OTTI as of December 31, 2014 or 2013. The weighted average duration of MBS was 4.0 years at December 31, 2014.
At December 31, 2014, we owned investment securities totaling $330.8 million in which the amortized cost basis exceeded fair value. Total unrealized losses on these securities were $3.6 million at December 31, 2014. The temporary impairment is the result of changes in market interest rates subsequent to the purchase of the securities. Our investment portfolio is reviewed each quarter for indications of other than temporary impairment. 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 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. In addition, 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.

Acquired Credit Impaired Loans	4. ACQUIRED CREDIT IMPAIRED LOANS
	On September 5, 2014, $24.2 million of impaired loans were acquired from FNBW. 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. Under ASC 310-30, acquired loans are generally considered accruing and performing loans as the loans accrete interest income over the estimated life of the loan when expected cash flows are reasonably estimable. Accordingly, acquired impaired loans that are contractually past due are still considered to be accruing and performing loans as long as the estimated cash flows are expected to be received. If the timing and amount of cash flows is not reasonably estimable, the loans may be classified as nonaccrual loans and interest income may be recognized on a cash basis or as a reduction of the principal amount outstanding. At December 31, 2014, there were three acquired loans accounted for under ASC 310-20 classified as nonaccrual loans with a carrying value of $217,000. There is no allowance for loan losses on any of the acquired loans, because any credit deterioration evident in the loans was included in the determination of the fair value of the loans at the acquisition date. Updates to expected cash flows for acquired impaired loans accounted for under ASC 310-30 may result in a provision for loan losses and the establishment of an allowance for loan losses to the extent the amount and timing of expected cash flows decrease compared to those originally estimated at acquisition.
	The following table details the impaired loans that are accounted for in accordance with ASC 310-30 as of September 5, 2014:

	The total amounts of loans serviced for others were $153.3 million, $229.8 million and $263.4 million at December 31, 2014, 2013 and 2012, respectively, which consisted of residential first mortgage loans and reverse mortgage loans. We received fees from the servicing of loans of $285,000, $342,000 and $359,000 during 2014, 2013 and 2012, respectively.
	We record mortgage-servicing rights on our mortgage loan-servicing portfolio. Mortgage servicing rights represent the present value of the future net servicing fees from servicing mortgage loans we acquire or originate. The value of these servicing rights was $321,000 and $419,000 at December 31, 2014 and 2013, respectively. Mortgage loans serviced for others are not included in loans in the accompanying Consolidated Statements of Condition. Changes in the fair value of these servicing rights resulted in net loss of $98,000 during 2014 and net income of $178,000 during 2013. Revenues from originating, marketing and servicing mortgage loans as well as valuation adjustments related to capitalized mortgage servicing rights are included in mortgage banking activities, net in the Consolidated Statements of Operations.

Allowance for Loan Losses and Credit Quality Information	6. ALLOWANCE FOR LOAN LOSSES AND CREDIT QUALITY INFORMATION
	Allowance for Loan Losses
	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 upon a continuing review of these portfolios. The following are included in our allowance for loan losses:

		•		Specific reserves for impaired loans

		•		Allowances for pools of homogenous loans based on historical net loss experience

		•		Adjustments for qualitative and environmental factors allocated to pools of homogenous loans

		•		Allowance for model estimation and complexity risk

	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 if 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. During the twelve months ended December 31, 2014, net charge-offs totaled $5.4 million, or 0.18% of average loans, compared to $9.9 million, or 0.34% of average loans during the twelve months ended December 31, 2013. We charge loans off when they are deemed to be uncollectible.
	Allowances 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 loan pools and retail loan pools. Commercial loans are pooled into the following segments: Commercial, Owner-Occupied, Commercial Real Estate 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. Probability of default is calculated based on the historical rate of migration to impaired status during the last 16 quarters. Loss severity is calculated as the actual loan losses (net of recoveries) on impaired loans in the respective pool during the same time frame. Retail loans are pooled into the following segments: residential mortgage and consumer loans. Pooled reserves for retail loans are calculated based solely on the previous four year average net loss rate.
	Qualitative adjustment factors consider various current internal and external conditions, are allocated among loan types and take into consideration the following:

		•		Assessment of current underwriting policies, staff, and portfolio mix

		•		Internal trends of delinquency, nonaccrual and criticized loans by segment

		•		Assessment of risk rating accuracy, control and regulatory assessments/environment

		•		General economic conditions — locally and nationally

		•		Market trends impacting collateral values

		•		Competitive environment as it could impact loan structure and underwriting
	The above factors are based on their relative standing compared to the period which historic losses are used in core reserve estimates and current directional trends. Each individual qualitative factor in our model can add or subtract to core reserves. A special adjustment factor of 7.5 basis points was applied to the commercial portfolio as additional qualitative consideration not taken into consideration in the qualitative factors. In addition, management has established a new special adjustment factor to address the absence of default history within the construction segment for certain risk ratings. This additional adjustment factor added $1.2 million in reserves to this segment which is equal to a 1.25% reserve for construction loans. Finally, a continued economic trend relative to the three and five year averages as well as current trends have resulted in the further reduction of other applied factors.
	The allowance methodology uses a loss emergence period (the period of time between an event that triggers the probability of a loss and the confirmation of the loss, LEP) of nine quarters based on generally improving economic conditions. Industry and historical data indicates that the LEP lengthens in an improving economy as the length of time between an adverse financial event and subsequent loss is extended.
	The final component of the allowance is a reserve for model estimation and complexity risk. The calculation of reserves is generally quantitative; however, qualitative estimates of valuations and risk assessment, and methodology judgements, are necessary. We review the qualitative estimates of valuation factors quarterly and management uses its judgment to make adjustments based on current trends. The model complexity risk factor was 5 basis points of total loans for December 31, 2014.
	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.

	The following tables provide an analysis of the allowance for loan losses and loan balances as of and for the year ended December 31, 2014 and December 31, 2013:

Non-Accrual and Past Due Loans
Nonaccruing loans are those on which the accrual of interest has ceased. 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 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 remain in accrual status because they are considered well secured and in the process of collection.
The following tables show our nonaccrual and past due loans at the dates indicated:

Impaired Loans
Loans for which it is probable we will not collect all principal and interest due according to contractual terms, which is 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. 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 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.

Interest income of $1.8 million and $922,000 was recognized on impaired loans during 2014 and 2013 respectively.

Reserves On Acquired Nonimpaired Loans
In accordance with FASB ASC 310, Receivables, loans acquired by the Bank through its merger with FNBW are required to be reflected on the balance sheet at their fair values as opposed to their book values on the date of acquisition. 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 fair value, 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 presently show no current 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. The 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. Borrowers 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 that 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 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 at December 31:

Troubled Debt Restructurings (TDR)
The balance of TDRs at December 31, 2014 and December 31, 2013 was $36.2 million and $27.6 million, respectively. The balances at December 31, 2014 include approximately $13.6 million of TDRs in nonaccrual status and $22.6 million of TDRs in accrual status compared to $15.3 million of TDRs in nonaccrual status and $12.3 million of TDRs in accrual status at December 31, 2013. Approximately $4.2 million and $4.1 million in related reserves have been established for these loans at December 31, 2014 and December 31, 2013, respectively.
A modification is classified as a TDR if both of the following exist: (1) the borrower is experiencing financial difficulty and (2) the Bank has granted a concession to the borrower. Many aspects of the borrower’s financial situation are assessed when determining whether they are experiencing financial difficulty. Concessions may include the reduction of an interest rate at a rate lower than current market rate for a new loan with similar risk, extension of the maturity date, reduction of accrued interest, or principal forgiveness. The assessments of whether a borrower is experiencing (or is likely to experience) financial difficulty and whether a concession has been granted is subjective in nature and management’s judgment is required when determining whether a modification is a TDR.
During 2014, the terms of 25 loans were modified in TDRs, of which seven were commercial loans and the remaining were residential and consumer loans. Our concessions on the restructured loans consisted of eight extensions of maturities, seven reductions in interest rates and four reductions of interest rates with extensions of maturities. Additionally, the TDRs included four bankruptcies and two forbearance agreements. Principal balances are generally not forgiven by us when a loan is modified as a TDR. Nonaccruing restructured loans may return to accrual status, if there has been a period of sustained repayment performance, typically six months, and repayment is reasonably assured.

The following table presents loans identified as TDRs during the twelve months ended December 31, 2014 and December 31, 2013:

The TDRs set forth in the table above increased our allowance for loan losses by $2.2 million through allocation of a related reserve, and resulted in charge-offs of $54,000 during the twelve months ended December 31, 2014. For the twelve months ended December 31, 2013, the TDRs set forth in the table above increased our allowance for loan losses by $82,000 through allocation of a related reserve, and resulted in charge-offs of $381,000.

Reverse Mortgages and Related Assets	Dec. 31, 2014
Mortgage Banking [Abstract]
Reverse Mortgages and Related Assets	7. REVERSE MORTGAGES AND RELATED ASSETS
	Reverse mortgages and related assets include only reverse mortgage loans as of December 31, 2014. In addition, prior to the clean-up call discussed below, the SASCO 2002-RM’s Class “O” certificates and the BBB-rated tranche of this reverse mortgage security were also included for the year ended December 31, 2013.
	Reverse mortgage loans are contracts in which a homeowner borrows against the equity in his/her home and receives cash in one lump sum payment, a line of credit, fixed monthly payments for either a specific term or for as long as the homeowner lives in the home, or a combination of these options. Since reverse mortgages are nonrecourse obligations, the loan repayments are generally limited to the sale proceeds of the borrower’s residence and the mortgage balance consists of cash advanced, interest compounded over the life of the loan and some may include a premium which represents a portion of the shared appreciation in the home’s value, if any, or a percentage of the value of the residence.
	In July 2011, we purchased 100% of SASCO 2002-RM1’s Class “O” certificates, representing equity ownership of a reverse mortgage securitization trust, for $2.5 million. This securitization was created in 2002 through the purchase of reverse mortgage loans owned by us, as well as an additional lender. As part of this securitization we retained the BBB rated tranche of this securitization and held this instrument as a trading asset.
	During the third quarter of 2013, we obtained the right to execute a clean-up call on the underlying collateral. This event led us to consolidate the assets and liabilities of the securitization trust, SASCO 2002 RM-1, on our Consolidated Statement of Condition in accordance with ASC 810, Consolidation as of December 31, 2013. As a result of consolidation of the reverse mortgage trust in 2013, a DTA was recorded at that time. However, because the reverse mortgage trust was not able to be consolidated for income tax purposes, a full valuation allowance was also recorded at that time on the DTA due to the uncertainty of realizing this benefit. On January 27, 2014, WSFS completed the legal call of the reverse mortgage trust bonds and the redemption of the trust’s preferred stockholders, eliminating this uncertainty since the reverse mortgage trust’s assets have now been combined with the Bank’s for tax purposes. As a result, WSFS removed the valuation allowance, and recorded a tax benefit of approximately $6.7 million during 2014.
	Our existing investment in reverse mortgages has been combined with the consolidated reverse mortgage loans for a total of $29.3 million at December 31, 2014. The portfolio consists of 112 loans with an average borrowers’ age of 93 years old and there is currently significant overcollateralization in the portfolio, as the realizable collateral value (the lower of collectible principal and interest, or appraised value and annual broker price opinion of the home) of $53.3 million well exceeds the outstanding book balance at December 31, 2014.

	The carrying value of the reverse mortgages is calculated by a model that uses the income approach as described in ASC 820-10-35-32. The model is a present value cash flow model, consistent with ASC 820-10-55-5 which describes the components of a present value measurement. The model incorporates the projected cash flows of the loans (includes payouts and collections) and then discounts these cash flows using the effective yield required on the life of the portfolio to reduce the net investment to zero at the time the final reverse mortgage contract is liquidated. The inputs to the model reflect our expectations of what other market participants would use in pricing this asset in a current transaction and therefore is consistent with ASC 820 that requires an exit price methodology for determining fair value.
	To determine the carrying value of these reverse mortgages as of December 31, 2014, we used a proprietary model and actual cash flow information to estimate future cash flows. There are three main drivers of cash flows 1) move-out rates, 2) house price appreciation HPA forecasts and 3) internal rate of return.

		1)	Move-out rates — The projections incorporate actuarial estimates of contract termination using mortality tables published by the Office of the Actuary of the United States Bureau of Census, adjusted for expected prepayments and relocations. During 2014 we updated these mortality tables to the new tables issued in October 2014.

		2)	House Price Appreciation — Consistent with other residential mortgage analyses from various market sources, we forecast a 2.5% increase in housing prices during 2015 and a 2.0% increase in the following year and thereafter. We believe this forecast continues to be appropriate given the nature of reverse mortgage collateral and historical under-performance to the broad housing market. Annually, during the fourth quarter, housing price estimates are updated through broker price opinions.

		3)	Internal Rate of Return — As of December 31, 2014, the internal rate of return (IRR) of 17.16% was the effective yield required on the life of the portfolio to reduce the net investment to zero at the time the final reverse mortgage contract is liquidated.
	As of December 31, 2014, the Company’s actuarially estimated cash payments to reverse mortgagors were as follows:


	Year Ending
	2015		$	712
	2016			576
	2017			461
	2018			365
	2019			285

	Years 2025 — 2029			143
	Years 2030 — 2034			21
	Thereafter			2

	Total		$	3,243


	This	table does not take into consideration cash inflow including payments from mortgagors or payoffs based on contractual terms.
	The amount of the contract value that would be forfeited if the Company were not to make cash payments to reverse mortgagors in the future is $7.9 million.
	The future cash flows depend on the HPA assumptions. If the future changes in collateral value were assumed to be zero, income would decrease by $641,000 for the year ended December 31, 2014 with an IRR of 15.60%. If the future changes in collateral value were assumed to be reduced by 1%, income would decrease by $321,000 with an IRR of 16.38%. For December 31, 2013, future cash flows depended on the HPA assumptions. The assumptions for 2013 were, if the future changes in collateral value were assumed to be zero, income would decrease by $155,000 for the year ended December 31, 2013 with an IRR of 12.50%. If the future changes in collateral value were assumed to be reduced by 1%, income would decrease by $77,000 with an IRR of 13.35%.

	The net present value of the projected cash flow depends on the IRR used. If the IRR increased by 1%, the net present value would increase by $478,000. If the IRR decreased by 1%, the net present value would decrease by $472,000.

In general, computer equipment, furniture and equipment and building renovations are expensed over three, five and ten years, respectively.
	We occupy certain premises including some with renewal options and operate certain equipment under noncancelable leases with terms ranging primarily from 1 to 25 years. These leases are accounted for as operating leases. Accordingly, lease costs are expensed as incurred in accordance with FASB ASC 840-20 Operating Leases. Rent expense was $9.5 million in 2014, $9.1 million in 2013 and $9.0 million in 2012. Future minimum cash payments under these leases at December 31, 2014 are as follows:

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	9. GOODWILL AND INTANGIBLE ASSETS
	In accordance with FASB ASC 805, Business Combinations, and FASB ASC 350, Intangibles — Goodwill and Other, all assets and liabilities acquired in purchase acquisitions, including goodwill, indefinite-lived intangibles and other intangibles are recorded at fair value.
	The fair value of acquired assets and liabilities, including the resulting goodwill, was based either on quoted market prices or provided by other third-party sources, when available. When third-party information was not available we made good-faith estimates primarily through the use of internal cash flow modeling techniques. The assumptions used in the cash flow modeling are subjective and susceptible to significant changes.
	Goodwill and other intangible assets with indefinite useful lives are tested for impairment at least annually and charged to results of operations in periods in which the recorded value is more than the estimated fair value. Intangible assets that have finite useful lives will continue to be amortized over their useful lives and are periodically evaluated for impairment. Goodwill totaled $48.7 million at December 31, 2014 and $32.2 million at December 31, 2013. The majority of this goodwill, or $43.5 million, is in the WSFS Bank reporting unit and is the result of a branch acquisition in 2008, the acquisition of Christiana Bank and Trust (CB&T) during 2010, the purchase of Array and Arrow during 2013, and the purchase of FNBW in 2014. The remaining goodwill is in the Trust and Wealth Management reporting unit and is mainly the result of the acquisition of CB&T.
	ASC 350, Intangibles—Goodwill and Other (Topic 350), states that an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. Therefore, before the first step of the existing guidance, the entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that the fair value of goodwill is less than carrying value. The qualitative assessment includes adverse events or circumstances identified that could negatively affect the reporting units’ fair value as well as positive and mitigating events. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step process is unnecessary. The entity has the option to bypass the qualitative assessment step for any reporting unit in any period and proceed directly to the first step of the existing two-step process. The entity can resume performing the qualitative assessment in any subsequent period.
	When required, the goodwill impairment test involves a two-step process. The first test is done by comparing the reporting unit’s aggregate fair value to its carrying value. Absent other indicators of impairment, if the aggregate fair value exceeds the carrying value, goodwill is not considered impaired and no additional analysis is necessary. If the carrying value of the reporting unit were to exceed the aggregate fair value, a second test would be performed to measure the amount of impairment loss, if any. To measure any impairment loss, the implied fair value would be determined in the same manner as if the reporting unit were being acquired in a business combination. If the implied fair value of goodwill is less than the recorded goodwill, an impairment charge would be recorded for the difference.
	Fair value may be determined using market prices, comparison to similar assets, market multiples, discounted cash flow analyses and other variables. Estimated cash flows extend five years into the future and, by their nature, are difficult to estimate over such an extended period of time. Factors that may significantly affect estimates include, but are not limited to, balance sheet growth assumptions, credit losses in our investment and loan portfolios, competitive pressures in our market area, changes in customer base and customer product preferences, changes in revenue growth trends, cost structure, changes in discount rates, conditions in the banking sector, and general economic variables.
	As of December 31, 2014, we assessed qualitative factors including macroeconomic conditions, industry and market conditions, cost factors, and overall financial performance in 2014 and determined that it was not more likely than not that the fair value of any of our reporting units was less than their respective carrying amounts. Therefore we did not perform the two-step impairment test for any of our reporting units in 2014. No impairment losses related to our goodwill were recorded in 2014 or 2013, however there can be no assurance that impairments of our goodwill will not occur in future periods.
	As of December 31, 2014, we had three operating segments, WSFS Bank, Cash Connect, and Trust & Wealth Management. Our operating segments may contain one or more reporting units depending on economic characteristics, products and customers. At the time we acquire a business, we allocate goodwill to the reporting unit where it will reside based on its relative fair value. Should we have significant business reorganization, we may reallocate the goodwill. For additional information on management reporting, see Note 20 to the Consolidated Financial Statements and Note 2 for additional information on the Goodwill that was recorded during 2014.

	The following table shows the allocation of goodwill to our reportable operating segments for purposes of goodwill impairment testing.

	FASB ASC 350 also 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. During 2014, we recorded intangible assets of $3.2 million due to the acquisition of FNBW. During 2013, we recorded intangible assets of $2.4 million due to the acquisition of Array and Arrow. See Note 2 to the Consolidated Financial Statements for additional information. The following table summarizes other intangible assets:

	Total other intangible assets	$	10,995	$	(4,252	)	$	6,743

	Core deposits are amortized over their expected lives using the present value of the benefit of the core deposits and straight-line methods of amortization. We recognized amortization expense on other intangible assets of $1.3 million, $1.0 million, and $989,000 for the years ended December 31, 2014, 2013, and 2012, respectively.
	The following presents the estimated amortization expense of intangibles:

	Thereafter		2,917

	Total	$	8,942
	At December 31, 2014, goodwill and other intangible assets were not considered impaired. Changing economic conditions that may adversely affect our performance and stock price could result in impairment, which could adversely affect earnings in the future.

	2016		—
	2017		128,728		0.96

		$	405,894		0.52

	Pursuant to collateral agreements with the FHLB, advances are secured by qualifying first mortgage loans, qualifying fixed-income securities, FHLB stock and an interest-bearing demand deposit account with the FHLB. During 2014, we executed $100.0 million of three year advances at an average rate of 1.0%. This strategy is intended to reduce interest rate risk.
	As a member of the FHLB, we are required to purchase and hold shares of capital stock in the FHLB in an amount at least equal to 0.35% of our member asset value plus 4.60% of advances outstanding. We were in compliance with this requirement with a stock investment in FHLB of $23.3 million at December 31, 2014 and $35.9 million as of December 31, 2013. This stock is carried on the accompanying Consolidated Statements of Condition at cost, which approximates liquidation value.
	The decrease in FHLB stock was due to the decrease in FHLB Advances outstanding. In February of 2012, the FHLB declared and began to pay a dividend on capital stock. We received dividends of $1.4 million and $391,000 for the years ended December 31, 2014 and 2013, respectively. For additional information regarding FHLB Stock, see Note 18 to the Consolidated Financial Statements.

	Federal Funds Purchased and Securities Sold Under Agreements to Repurchase
	During 2014 and 2013, we purchased federal funds as a short-term funding source. At December 31, 2014, we had purchased $103.2 million in federal funds at an average rate of 0.27%. At December 31, 2013, we had purchased $72.0 million in federal funds at a rate of 0.28%.
	During 2014, we continued to have securities sold under agreements to repurchase as a funding source. At December 31, 2014, securities sold under agreements to repurchase had a fixed rate of 2.98%. These repurchases matured on January 1, 2015. The underlying securities are mortgage-backed securities with a fair value of $35.5 million at December 31, 2014. Securities sold under agreements to repurchase with the corresponding carrying and fair values of the underlying securities are due as follows:


		Borrowing		Rate			Collateral
	(In Thousands)	Amount					Carrying		Fair		Accrued
	(In Thousands)						Value		Value		Interest
	2014
	Over 90 days	$	25,000		2.98	%	$	35,886	$	35,549	$	64

	2013
	Over 90 days	$	25,000		2.98	%	$	34,952	$	33,596	$	83

	Trust Preferred Borrowings
	In 2005, we issued $67.0 million of aggregate principal amount of Pooled Floating Rate Securities at a variable interest rate of 177 basis points over the three-month LIBOR rate. These securities are callable and have a maturity date of June 1, 2035.
	Senior Debt
	In 2012, we issued and sold $55.0 million in aggregate principal amount of 6.25% Senior Notes due 2019 (the Senior Debt). The Senior Debt is unsecured and ranks equally with all of our other present and future unsecured unsubordinated obligations. The senior debt is effectively subordinated to our secured indebtedness and structurally subordinated to the indebtedness of our subsidiaries. At our option, the Senior Debt is callable, in whole or in part, after five years. The Senior Debt matures on September 1, 2019.
	Reverse Mortgage Trust Bonds Payable
	In conjunction with consolidating reverse mortgage loans through consolidation of a reverse mortgage securitization, we recognized the securitization bonds on our Consolidated Statements of Condition. The bonds had a carrying value of $21.9 million and carry an interest rate of 30 day LIBOR plus 300 basis points. We completed the legal call of the bonds on January 27, 2014. See Note 7 to the Consolidated Financial Statements.
	Other Borrowed Funds
	Included in other borrowed funds are collateralized borrowings of $11.6 million and $24.7 million at December 31, 2014 and 2013, respectively, consisting of outstanding retail repurchase agreements, contractual arrangements under which portions of certain securities are sold overnight to retail customers under agreements to repurchase. Such borrowings were collateralized by mortgage-backed securities. The average rates on these borrowings were 0.08% and 0.09% at December 31, 2014 and 2013, respectively.
Borrower in Custody
As of December 31, 2014, the Bank had $177.0 million of loans pledged to the Federal Reserve Bank of Philadelphia (FRB) as collateral for discount window borrowings. The Bank did not borrow funds from the FRB during 2014.

	In 2009 we completed a private placement of stock to Peninsula Investment Partners, L.P. (Peninsula), pursuant to which the Company issued and sold 862,069 shares of common stock for a total purchase price of $25.0 million, and a 10-year warrant to purchase 129,310 shares of common stock at an exercise price of $29.00 per share. The warrant was immediately exercisable. Total proceeds of $25.0 million were allocated, based on the relative fair value of common stock and common stock warrants, to common stock for $23.5 million and common stock warrants for $1.5 million. During 2014, we entered into an agreement in which the Company repurchased the warrants for $6.3 million.
	In 2009, we entered into a purchase agreement with the U.S. Treasury pursuant to which the Company issued and sold 52,625 shares of our fixed-rate cumulative perpetual preferred stock for a total purchase price of $52.6 million, and a 10-year warrant to purchase 175,105 shares of common stock at an exercise price of $45.08 per share. During 2013 we declared and paid $1.8 million of cash dividends on the preferred stock. In 2012 and 2011 the Company declared and paid $2.6 million of cash dividends. On September 12, 2012 we entered into a letter agreement with the U.S. Treasury pursuant to which the Company repurchased the warrant for $1.8 million.
	In 2010, we completed an underwritten public offering of 1,370,000 shares of common stock and raised $47.1 million, net of $2.9 million of costs.
	During 2013, we received regulatory non-objection to repurchase/redeem the Company’s cumulative perpetual preferred stock using available cash on hand. Late in the second quarter of 2013, the Company repurchased $20.0 million of the $52.6 million outstanding in open market transactions (at or very near par value), and redeemed the remaining preferred stock at the stated liquidation (par) value of $1,000 per share in the third quarter.
	During 2014, the Board of Directors approved a stock buyback program of up to 5% of total outstanding shares of common stock. Related to this authorization, the Company repurchased 116,421 common shares and common share equivalents at an average implied price of $77.18 during 2014. These buybacks included 81,233 common share equivalents related to the repurchase of 129,310 warrants to purchase common stock issued in conjunction with a 2009 equity offering. The Company has approximately 353,000 shares (4% of its 9.4 million shares outstanding), remaining to repurchase under its current authorization.

Stockholders' Equity and Regulatory Capital	13. STOCKHOLDERS’ EQUITY AND REGULATORY CAPITAL
	Under guidelines issued by banking regulators in effect as of December 31, 2014, savings institutions such as the Bank have maintained “tangible” capital equal to 1.5% of adjusted total assets, “core” capital equal to 4.0% of adjusted total assets, “Tier 1” capital equal to 4.0% of risk weighted assets and “total” or “risk-based” capital (a combination of core and “supplementary” capital) equal to 8.0% of risk weighted assets. Failure to meet minimum capital requirements can initiate certain mandatory actions and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our bank’s financial statements. At December 31, 2014 and 2013, the Bank was in compliance with regulatory capital requirements and was deemed a “well-capitalized” institution.
	The following table presents the capital position of the Bank as of December 31, 2014 and 2013:

	The Holding Company
	As of December 31, 2014, our capital structure includes one class of stock, $0.01 par common stock outstanding with each share having equal voting rights. During 2013, our preferred stock was fully redeemed at par.
	In 2005, WSFS Capital Trust III, our unconsolidated subsidiary, issued Pooled Floating Rate Securities at a variable interest rate of 177 basis points over the three-month LIBOR rate with a scheduled maturity of June 1, 2035. The par value of these securities is $2.0 million and the aggregate principal is $67.0 million. The proceeds from the issue were invested in Junior Subordinated Debentures the Company issued. These securities are treated as borrowings with interest included in interest expense on the Consolidated Statements of Operations. At December 31, 2014, the coupon rate of the WSFS Capital Trust III securities was 2.01%. The effective rate will vary due to fluctuations in interest rates.
	When infused into the Bank, the Trust Preferred Securities issued in 2005 qualify as Tier 1 capital. The Bank is prohibited from paying any dividend or making any other capital distribution if, after making the distribution, the Bank would be undercapitalized within the meaning of the Prompt Corrective Action regulations.
	At December 31, 2014, $54.3 million in cash remains at the holding company to support the parent company’s needs.
	Pursuant to federal laws and regulations, our ability to engage in transactions with affiliated corporations, including the loan of funds to, or guarantee of the indebtedness of, an affiliate, is limited.

Compensation and Retirement Disclosure [Abstract]
Associate (Employee) Benefit Plans	14. ASSOCIATE (EMPLOYEE) BENEFIT PLANS
	Associate 401(k) Savings Plan
	Certain subsidiaries of ours maintain a qualified plan in which Associates may participate. Participants in the plan may elect to direct a portion of their wages into investment accounts that include professionally managed mutual and money market funds and our common stock. Generally, the principal and related earnings are tax deferred until withdrawn. We match a portion of the Associates’ contributions. As a result, our total cash contributions to the plan on behalf of our Associates resulted in an expense of $2.2 million, $2.6 million, and $2.4 million for 2014, 2013, and 2012, respectively.
	All contributions are invested in accordance with the Associates’ selection of investments. If Associates do not designate how discretionary contributions are to be invested, 100% will be invested in a balanced fund. Associates may generally make transfers to various other investment vehicles within the plan. The plan’s yearly activity includes net sales of 2,000 of our common stock in 2014 and net purchases of 19,000, and 2,000 shares of our common stock during 2013 and 2012, respectively.
	Postretirement Benefits
	We share certain costs of providing health and life insurance benefits to eligible retired Associates 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. The change will impact our net periodic benefit cost; however, this impact was partially offset by a change in the assumptions used to determine these costs. The discount rate decreased 100 basis points compared to the prior year, the future rates of participation were changed from 50% to 15%, and the mortality table was updated during 2014 to the new mortality tables issued by the Office of the Actuary of the United Sates Bureau of Census in October 2014.
	We account for our obligations under the provisions of FASB ASC 715, Compensation — Retirement Benefits (ASC 715). ASC 715 requires that the costs of these benefits be recognized 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.

	ASC 715 requires that we recognize the funded status of our defined benefit postretirement plan in our statement of financial position, with a corresponding adjustment to accumulated other comprehensive income, net of tax. The adjustment to accumulated other comprehensive income at adoption represented the net unrecognized actuarial losses and unrecognized transition obligation remaining from the initial adoption of ASC 715, all of which were previously netted against the plan’s funded status in our statement of financial position pursuant to the provisions of ASC 715. These amounts will be subsequently recognized as net periodic pension costs pursuant to our historical accounting policy for amortizing such amounts. Further, actuarial gains and losses that arise in subsequent periods, and are not recognized as net periodic pension cost in the same periods, will be recognized as a component of other comprehensive income. Those amounts will be subsequently recognized as a component of net periodic pension cost on the same basis as the amounts recognized in accumulated other comprehensive income at adoption of ASC 715.
	In accordance with ASC 715, during 2015 we expect to recognize $20,000 of amortization related to the net actuarial loss, and $76,000 relating to the net transition obligation.

We assume medical benefits will increase at an average rate of 5% per annum. The costs incurred for retirees’ health care are limited since certain current and all future retirees are restricted to an annual medical premium cap indexed (since 1995) by the lesser of 4% or the actual increase in medical premiums paid by us. For 2014, this annual premium cap amounted to $3,037 per retiree. We estimate that we will contribute approximately $3,158 per retiree to the plan during fiscal 2015.
We have five additional plans which are no longer being provided to Associates. There is a Supplemental Pension Plan with a corresponding liability of $856,000 and $381,000 for December 31, 2014 and December 31, 2013, respectively. An Early Retirement Window Plan with a corresponding liability of $179,000 and $149,000 for December 31, 2014 and December 31, 2013, respectively. A Director’s Plan with a corresponding liability of $60,000 and $44,000 for December 31, 2014 and December 31, 2013, respectively. A Supplemental Executive Retirement Plan with a corresponding liability of $1,490,000 and $932,000 for December 31, 2014 and December 31, 2013, respectively, and a Post-Retirement Medical Plan with a corresponding liability of $147,000 and $164,000 for December 31, 2014 and December 31, 2013, respectively.

Income Tax Disclosure [Abstract]
Taxes on Income	15. TAXES ON INCOME
	The Company and its subsidiaries file a consolidated federal income tax return and separate state income tax returns. Our income tax provision consists of the following:


	Year Ended December 31,	2014			2013			2012
	(In Thousands)
	Current income taxes:
	Federal taxes	$	20,078		$	21,242		$	11,136
	State and local taxes		3,215			2,759			2,256
	Deferred income taxes:
	Federal taxes		(5,575	)		875			3,591
	State and local taxes		(89	)		(120	)		—

	Total	$	17,629		$	24,756		$	16,983

	Current federal income taxes include taxes on income that cannot be offset by net operating loss carryforwards.

	Deferred income taxes 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. The following is a summary of the significant components of our deferred tax assets and liabilities as of December 31, 2014 and 2013:


	(In Thousands)	2014			2013
	Deferred tax assets:
	Unrealized losses on available-for-sale securities	$	—		$	12,762
	Allowance for loan losses		13,799			14,436
	Loans		3,016			—
	Reserves and other		10,400			8,854
	Deferred gains		761			453
	Net operating losses		1,104			1,196
	Reverse mortgages		3,707			3,686

	Total deferred tax assets before valuation allowance		32,787			41,387

	Less: valuation allowance		—			(4,882	)

	Total Deferred tax assets	$	32,787		$	36,505

	Deferred tax liabilities:
	Unrealized gains on available-for-sale securities	$	(1,626	)	$	—
	Bad debt recapture		(1,233	)		—
	Accelerated depreciation		(1,915	)		(1,506	)
	Other		(267	)		(2,132	)
	Prepaid expenses		(741	)		(1,112	)
	Deferred loan costs		(1,904	)		(1,843	)
	Intangibles		(3,349	)		(1,765	)

	Total deferred tax liabilities		(11,035	)		(8,358	)

	Net deferred tax asset	$	21,752		$	28,147

	Included in the table above is the effect of certain temporary differences for which no deferred tax expense or benefit was recognized. In 2014, such items consisted primarily of $1.6 million of unrealized gains on certain investments in debt and equity securities accounted for under ASC 320 along with $258,000 related to postretirement benefit obligations accounted for under ASC 715. In 2013, they consisted primarily of $12.8 million of unrealized losses on certain investments in debt and equity securities along with $550,000 related to postretirement benefit obligations.
	Based on our history of prior earnings and our expectations of the future, it is anticipated that operating income and the reversal pattern of our temporary differences will, more likely than not, be sufficient to realize a net deferred tax asset of $21.8 million at December 31, 2014.
	As a result of the acquisition of the First National Bank of Wyoming (FNBW), we recorded a net deferred tax asset (DTA) of $3.1 million. Included in this DTA are $1.9 million of net operating loss (NOL) carryovers and $309,000 of alternative minimum tax credit carryovers. Such NOLs expire beginning in 2034, while the tax credits have an indefinite life. Although there is a limitation on the amount of FNBW’s net operating loss deduction (and certain other deductions) that we can utilize each tax year, we expect to fully utilize these tax attributes and, therefore, no valuation allowance has been recorded against the DTA.

	A reconciliation showing the differences between our effective tax rate and the U.S. Federal statutory tax rate is as follows:


	Year Ended December 31,	2014			2013			2012
	Statutory federal income tax rate		35	%		35	%		35	%
	State tax, net of federal tax benefit		2.8			2.4			3
	Interest income 50% excludable		—			—			(0.5	)
	Tax-exempt interest		(2.0	)		(1.2	)		(0.5	)
	Bank-owned life insurance income		(0.3	)		(0.1	)		(1.1	)
	Incentive stock option and other nondeductible compensation		—			0.3			0.6
	Tax benefits from previously unconsolidated subsidiary (SASCO)		(9.4	)		—			—
Federal tax credits		(1.7	)		(1.7	)		(1.4	)
Other		0.3			(0.1	)		0.1

Effective tax rate		24.7	%		34.6	%		35.2	%

As a result of the consolidation for accounting purposes of the SASCO reverse mortgage securitization trust during 2013, a deferred tax asset of approximately $4.9 million was recorded. In addition we recorded a $1.8 million deferred tax liability associated with our investment in SASCO. However, because SASCO was not consolidated for income tax purposes, a full valuation allowance was also recorded on this DTA due to the uncertainty of its realization, as the realization was dependent on future taxable income. On January 27, 2014 the separate company SASCO tax structure was eliminated, which permits tax consolidation within the Bank’s tax return filings on a prospective basis. At this date, the uncertainty surrounding the realization of the DTA was eliminated. Accordingly, we removed the $4.9 million valuation allowance and eliminated the $1.8 million deferred tax liability, which resulted in an overall income tax benefit of $6.7 million in 2014. Finally, SASCO has $1.2 million of remaining Federal net operating losses that the Bank acquired upon SASCO’s liquidation. Such NOLs expire beginning in 2030.
We account for income taxes in accordance with FASB Accounting Standards Codification (ASC) 740, Income Taxes (formerly Statement of Financial Accounting Standards (SFAS) No. 109, Accounting for Income Taxes and FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement 109). ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. Benefits from tax positions are recognized in the financial statements only when it is more-likely-than-not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. ASC 740 also provides guidance on the accounting for and disclosure of unrecognized tax benefits, interest and penalties.
We record interest and penalties on potential income tax deficiencies as income tax expense. Federal tax years 2011 through 2014 remain subject to examination as of December 31, 2014, while tax years 2011 through 2014 remain subject to examination by state taxing jurisdictions. During 2013, the audit of our 2010 federal tax return was completed by the IRS. We recorded a $186,000 tax benefit as a result of settling this audit. No state income tax return examinations are currently in process. We do not expect to record or realize any material unrecognized tax benefits during 2015.
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 are no longer any unrecognized tax benefits related to ASC 740 as of December 31, 2014 nor has there been any unrecognized tax benefit activity since December 31, 2012.

StockBased_Compensation

Stock-Based Compensation	12 Months Ended
Stock-Based Compensation	Dec. 31, 2014
Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	16. STOCK-BASED COMPENSATION
	Stock-based compensation is accounted for in accordance with FASB ASC 718, Stock Compensation. After shareholder approval in 2005, the 1997 Stock Option Plan (1997 Plan) was replaced by the 2005 Incentive Plan (2005 Plan). Upon stockholder approval in 2013, the 2005 Incentive Plan was amended and replaced by the 2013 Incentive Plan (2013 Plan). No future awards may be granted under the 2005 Plan, however, we still have options outstanding under the 1997 Plan and 2005 Plan for our officers, directors and employees of us and our subsidiaries (Associates). The 2013 Plan will terminate on the tenth anniversary of its effective date, after which no awards may be granted. Collectively, the 1997 Plan, 2005 Plan and 2013 Plan are referred to as Stock Incentive Plans. The number of shares reserved for issuance under the 2013 Plan is 698,845. At December 31, 2014, there were 361,157 shares available for future grants under the 2013 Plan.
	With the exception of certain Performance Stock Awards, the Stock Incentive Plans provide for the granting of incentive stock options as defined in Section 422 of the Internal Revenue Code as well as non-incentive stock options (collectively, Stock Options). Additionally, the 2013 Plan provides for the granting of stock appreciation rights, performance awards, restricted stock and restricted stock unit awards, deferred stock units, dividend equivalents, other stock-based awards and cash awards. All Stock Options are to be granted at not less than the market price of our common stock on the date of the grant. With the exception of certain Non-Plan Stock Options (as defined below), all Stock Options granted during 2014, 2013 and 2012 vest in 25% per annum increments, start to become exercisable one year from the grant date and expire between five and seven years from the grant date. We use the simplified method provided for in Staff Accounting Bulletin (SAB Topic 14.D.2) to estimate the expected term of options. New shares are issued for all option exercises. Generally, all awards become exercisable immediately in the event of a change in control, as defined within the Stock Incentive Plans. In addition, the Black-Scholes option-pricing model is used to determine the grant date fair value of Stock Options.
	Stock Options
	A summary of the status of our Stock Incentive Plans as of December 31, 2014, 2013 and 2012, respectively, and changes during those years are presented below:

	At January 1, 2014 there were non-vested options with a $17.9 million intrinsic value. Stock Options that vested during 2014 had an intrinsic value of $2.6 million and options that were exercised had an intrinsic value of $2.4 million. In addition, there were vested options that expired with an intrinsic value of $220,000. The exercisable options remaining at December 31, 2014, had an intrinsic value of $2.9 million and an average remaining contractual term of 1.9 years. At December 31, 2014 outstanding options had an intrinsic value of $18.4 million and an average remaining contractual term of 4.3 years.

	The following table provides information about our unvested stock options outstanding at December 31, 2014, 2013 and 2012, respectively:

	The total amount of unrecognized compensation cost related to nonvested stock options as of December 31, 2014 was $4.8 million. The weighted-average period over which the expense is expected to be recognized is 3.0 years. We issue new shares upon the exercise of options.
	On April 25, 2013 stockholders approved a change in future compensation for Mark A. Turner, President and CEO. As a result, Mr. Turner was granted 250,000 non-statutory stock options (Non-Plan Stock Options) with a longer and slower vesting schedule than our standard options, 40% vesting after the second year and 20% vesting in each of the following three years. Additionally, these options were awarded at an exercise price of 20% over the December 2012 market value (the date on which framework of the plan was decided). Upon the grant, Mr. Turner is no longer eligible to receive grants under any of our other stock based award programs for a period of five years. The Black-Scholes option-pricing model was used to determine the grant date fair value of options. Significant assumptions used in the model included a weighted-average risk-free rate of return (zero coupon treasury yield) of 0.76% in 2013; an expected option life of five years; and an expected stock price volatility of 40.5% in 2013. For the purposes of this option-pricing model, a dividend yield of 1.01% was assumed.
	Additionally, as a result of the stockholder approval, 150,000 incentive stock options were issued to certain executive officers of the Company under the 2013 Plan. These options have the same vesting schedule and exercise price as the Non-Plan Stock Options granted to Mr. Turner. The Black-Scholes option-pricing model was used to determine the grant date fair value of options and had the same significant assumptions used in the model as those used to value Mr. Turner’s options.
	During 2013, we granted 122,357 additional options with a five-year life and a four-year vesting period. The Black-Scholes option-pricing model was used to determine the grant date fair value of the options. Significant assumptions used in the model included a weighted-average risk-free rate of return (zero coupon treasury yield) of 0.5% in 2013 an expected option life of three years and nine months; and an expected stock price volatility of 30.7% in 2013. For the purposes of this option-pricing model, a dividend yield of 1.01% was assumed.
	During 2014, we granted 43,686 additional options with a seven-year life and a four-year vesting period. The Black-Scholes option-pricing model was used to determine the grant date fair value of options. Significant assumptions used in the model included a weighted-average risk-free rate of return (zero coupon treasury yield) of 0.97% in 2014; an expected option life of four years and nine months; and an expected stock price volatility of 29.0% in 2014. For the purposes of this option-pricing model, a dividend yield of 0.67% was assumed.

	The following table summarizes all outstanding Stock Options for option plans as of December 31, 2014, segmented by range of exercise prices:

Restricted Stock and Restricted Stock Units
During 2014, we issued 10,097 restricted stock units (RSUs) and restricted stock awards (RSAs). These awards vest over a four year period. The total amount of compensation cost to be recognized relating to non-vested restricted stock as of December 31, 2014, was $940,000. This compares to $1.2 million at December 31, 2013 and $992,000 at December 31, 2012. The weighted-average period over which the cost is expected to be recognized is 2.4 years.
Compensation costs related to these issuances are recognized over the lives of the restricted stock and RSUs. We amortize the expense related to the restricted stock grants into salaries, benefits and other compensation expense on an accrual basis over the requisite service period for the entire award. When we award restricted stock to individuals from whom we may not receive services in the future, we recognize the expense of restricted stock grants when we make the award, instead of amortizing the expense over the vesting period of the award.
The following table summarizes the Company’s RSUs and RSAs and changes during the year:


		Units				Weighted Average
		(in whole)				Grant-Date Fair
						Value per Unit
Balance at December 31, 2013			53,826			$	43.01
Granted			10,097				71.15
Exercised/Converted			(22,770	)			42.44
Canceled			(1,457	)			34

Balance at December 31, 2014			39,696			$	50.83
At January 1, 2014 there were 53,340 non-vested RSUs and RSAs with a $4.1 million intrinsic value. RSUs and RSAs granted during 2014 had an intrinsic value of $778,000. RSUs and RSAs that were exercised/converted during 2014 had an intrinsic value of $1.7 million. RSUs and RSAs canceled during 2014 had an intrinsic value of $112,000 The unvested RSUs and RSAs remaining at December 31, 2014, had an intrinsic value of $3.1 million and an average remaining contractual term of 2.3 years.
Performance Stock Awards
The Long-Term Performance-Based Restricted Stock Unit program (Long-Term Program) provided for awards up to an aggregate of 77,800 shares of our stock to the remaining 14 participants, only after the achievement of targeted levels of return on assets (ROA) in any year through 2013. During 2013, the company achieved the 1.00% performance level of return on assets. In accordance with the Long-Term Program, we issued 36,152 RSUs to the plan’s participants. The awarded stock will vest in 25% increments over four years. During 2014, we recognized $442,000 of compensation expense related to this program.
The Board approved a plan in which Marvin N. Schoenhals, Chairman of the Board, was granted 22,250 shares of restricted stock effective January 3, 2011 with a five-year performance vesting schedule starting at the end of the second year following the grant date. These shares are subject to vesting in whole or in part based on the role that Mr. Schoenhals plays in establishing new business over a two year period of time that achieves over a two year period a result of at least a 50% return on investment of the cost of the restricted stock. We recognized compensation expense of $275,000 related to this award in 2014.
The impact of stock-based compensation (all options and restricted shares) for the year ended December 31, 2014 was $3.7 million pre-tax ($2.6 million after tax) to salaries, benefits and other compensation. This compares to $3.2 million pre-tax ($2.5 million after tax) in 2013, and $2.3 million pre-tax ($1.7 million after tax) in 2012.

	Data Processing Operations
	We have entered into contracts to manage our network operations, data processing and other related services. The projected amounts of future minimum payments contractually due (in thousands) are as follows:


	Year	Amount
	2015	$	4,831
	2016		4,491
	2017		4,269
	2018		3,130
	2019		3,186
	The expenses for data processing and operations for the year ending December 31, 2014 were $6.1 million, compared to $5.9 million for the year ended December 31, 2013 and $5.6 million for the year ended December 31, 2012.
	Legal Proceedings
	In the ordinary course of business, we are subject to legal actions that involve claims for monetary relief. For additional information regarding legal proceedings, see Note 23 to the Consolidated Financial Statements.
	Financial Instruments With Off-Balance Sheet Risk
	We are a party to financial instruments with off-balance sheet risk in the normal course of business primarily to meet the financing needs of our customers. To varying degrees, these financial instruments involve elements of credit risk that are not recognized in the Consolidated Statement of Condition.
	Exposure to loss for commitments to extend credit and standby letters of credit written is represented by the contractual amount of those instruments. We generally require collateral to support such financial instruments in excess of the contractual amount of those instruments and use the same credit policies in making commitments as we do for on-balance sheet instruments.

	The following represents a summary of off-balance sheet financial instruments at year-end:


	December 31,	2014		2013
	(In Thousands)
	Financial instruments with contract amounts which represent potential credit risk:
	Construction loan commitments	$	99,917	$	64,210
	Commercial mortgage loan commitments		16,110		9,852
	Commercial loan commitments		393,028		335,257
	Commercial owner-occupied commitments		33,302		32,078
	Commercial standby letters of credit		47,667		56,651
	Residential mortgage loan commitments		22,617		5,018
	Consumer loan commitments		168,391		150,265
	At December 31, 2014, we had total commitments to extend credit of $781.0 million. Almost all of the consumer lines of credit of $168.4 million were secured by real estate. Residential mortgage loan commitments generally have closing dates within a one-month period but can be extended to six months in some cases. Not reflected in the table above are commitments to sell residential mortgages of $34.6 million, $24.2 million at December 31, 2014 and 2013, respectively. We did not have commitments to sell residential mortgages in 2012.
	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being completely drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. We evaluate each customer’s creditworthiness and obtain collateral based on our credit evaluation of the counterparty.
	Indemnifications
	Secondary Market Loan Sales. Given the current interest rate environment, coupled with our desire not to hold these assets in our portfolio, we generally 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 Freddie Mac (FHLMC), Fannie Mae (FNMA), and the Federal Home Loan Bank (FHLB). Loans Held-for-Sale are reflected on our Balance Sheet at this fair value with changes in the value reflected in our Consolidated Statements. Gains and losses are recognized at the time of sale. We periodically retain the servicing rights on residential mortgage loans sold which result in monthly service fee income and are included in our Mortgage Servicing Rights (MSRs). Otherwise, we sell loans with servicing released on a nonrecourse basis. Rate-locked loan commitments we intend to sell in the secondary market are accounted for as derivatives under the guidance promulgated in FASB ASC Topic 450, Contingencies.
	We generally do not sell loans with recourse, except for standard loan sale contract provisions covering violations of representations and warranties and, under certain circumstances, early payment default by the borrower. These are customary repurchase provisions in the secondary market for residential mortgage loan sales. These provisions may include either an indemnification from loss or the repurchase of the loans. Repurchases and losses have been rare and no provision is made for losses at the time of sale. There were two repurchases totaling $354,000 for the year ended December 31, 2014 and no such repurchases for the year ended December 31, 2013.
	Swap Guarantees. We entered into agreements with four unrelated financial institutions whereby those financial institutions entered into interest rate derivative contracts (interest rate swap transactions) with customers referred to them by us. By the terms of the agreements, those financial institutions have recourse to us for any exposure created under each swap transaction in the event 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 smaller financial institutions like 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 under FASB ASC Topic 450, Contingencies.

	At December 31, 2014, there were 101 variable-rate to fixed-rate swap transactions between the third-party financial institutions and our customers. The initial notional aggregated amount was approximately $417.9 million, with maturities ranging from three months to eleven years. The aggregate fair value of these swaps to the customers was a liability of $16.5 million as of December 31, 2014, of which 99 swaps, with a liability of $16.5 million, were in paying positions to a third party. We had no reserves for the swap guarantees.
	At December 31, 2013, there were 101 variable-rate to fixed-rate swap transactions between the third-party financial institutions and our customers. The initial notional aggregated amount was approximately $423.9 million, with maturities ranging from three months to twelve years. The aggregate fair value of these swaps to the customers was a liability of $17.8 million as of December 31, 2013, of which 89 swaps, with a liability of $18.2 million, were in paying positions to a third party. We had reserves of $70,000 for the swap guarantees.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	18. FAIR VALUE DISCLOSURES
	Fair Value of Financial Assets and Liabilities
	ASC 820-10, Fair Value Measurements and Disclosure, 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.
	A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.

	The table below presents the balances of assets measured at fair value as of December 31, 2014 (there are no material liabilities measured at fair value):

	Fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon 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 December 31, 2014, securities classified as available for sale are reported at fair value using Level 2 inputs. Included in the Level 2 total are approximately $30.0 million in Federal Agency debentures, and $710.2 million in Federal Agency MBS. We believe that this Level 2 designation is appropriate for these securities under ASC 820-10 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 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 lower of the loan balance or 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
During 2014 we elected to record loans held-for-sale at their fair value. The fair value was estimated using Level 2 inputs based on value information provided by brokers.
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 range from 10% — 50%. 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.
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, has a gross amount of $46.7 million and $43.3 million at December 31, 2014 and December 31, 2013, respectively. The valuation allowance on impaired loans was $5.3 million as of December 31, 2014 and $4.9 million as of December 31, 2013.
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 Short-Term Investments
For cash and short-term investments, including due from banks, federal funds sold, securities purchased under agreements to resell and interest-bearing deposits with other banks, the carrying amount is a reasonable estimate of fair value.

Investments and Mortgage-Backed Securities
Since quoted market prices are not available, 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. The fair value of our investment in reverse mortgages is based on the net present value of estimated cash flows, which have been updated to reflect recent external appraisals of the underlying collateral. For additional discussion of our mortgage-backed securities-trading or our internally developed models, see “Fair Value of Financial Assets” in Note 10 to the Consolidated Financial Statements.
Stock in the Federal Home Loan Bank of Pittsburgh
The fair value of FHLB stock is assumed to be essentially equal to its cost basis, since the stock is non-marketable but redeemable at its par value.
Loans held-for-sale
Loans held-for-sale are carried at their fair value.
Loans
Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type: commercial, commercial mortgages, construction, residential mortgages and consumer. For loans that reprice frequently, the book value approximates fair value. The fair values of other types of loans 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 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 utilized if appraisals are not available. This technique does not contemplate an exit price.
Reverse Mortgage Related Assets
For additional information on these reverse mortgage related assets, see Note 7, Reverse Mortgage Related Assets, to the Consolidated Financial Statements.
Demand Deposits, Savings Deposits and Time Deposits
The fair value 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 fair value of existing debt.
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.
Other Assets
WSFS holds 50,833 shares of Visa Class B stock. Following resolution of Visa’s covered litigation, shares of Visa Class B stock will be converted to Visa Class A shares (the current conversion rate is 0.4121 shares of Class A stock for each share of Class B stock). As our ownership is related to our prior participation in Visa’s network, while Visa operated as a cooperative, this ownership is recorded on our books with zero basis.

While only current owners of Class B shares are allowed to purchase other Class B shares, there have been several transactions between Class B shareholders. Based on these transactions we estimate the value of our Class B shares to be $4.8 million as of December 31, 2014.
The book value and estimated fair value of our financial instruments are as follows:

Related Party Transactions	19. RELATED PARTY TRANSACTIONS
Related Party Transactions	We routinely enter into transactions with our directors and officers. These related party transactions are made in the ordinary course of business on substantially the same terms and conditions, including interest rates and collateral, as those prevailing at the same time for comparable transactions with other customers. They do not, in the opinion of management, involve more than the normal credit risk or present other unfavorable features. The outstanding balance of loans to related parties at December 31, 2014 and 2013 was $2.9 million and $2.0 million, respectively. Total deposits to related parties at December 31, 2014 and 2013 was $4.2 million and $3.8 million, respectively. During 2014, new loans and credit line advances to related parties amounted to $1.2 million and repayments amounted to $471,000.

Segment Reporting [Abstract]
Segment Information	20. SEGMENT INFORMATION
	In accordance with FASB ASC 280, Segment Reporting (ASC 280) (Formerly SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information) we discuss our business in three segments. 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 ordinary 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 Consolidated Financial Statements. There is one segment for each of WSFS Bank, Cash Connect, and Trust and Wealth Management.

	The WSFS Bank segment provides financial products to commercial and retail customers through its 55 offices located in Delaware (45), Pennsylvania (8) and Virginia (1) and Nevada (1). Retail and Commercial Banking, Commercial Real Estate Lending and other banking business units are operating departments of WSFS. 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. Because of these and other reasons, these departments are not considered discrete segments and are appropriately aggregated within the WSFS Bank segment in accordance with ASC 280.
	Cash Connect provides turnkey ATM services through strategic partnerships with several of the largest networks, manufacturers and service providers in the ATM industry. 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 Trust and Wealth Management division provides a broad array of fiduciary, investment management, credit and deposit products to clients through four business lines. Wealth Investments, Inc. provides insurance and brokerage products primarily to our retail banking clients. Cypress Capital Management, LLC is a registered investment advisor with over $661 million in assets under management. Cypress’ primary market segment is high net worth individuals, offering a ‘balanced’ investment style focused on preservation of capital and current income. Christiana Trust, with $8.6 billion in assets under management and administration, provides fiduciary and investment services to personal trust clients, and trustee, agency, custodial and commercial domicile services to corporate and institutional clients. WSFS Private Banking serves high net worth clients by delivering credit and deposit products and partnering with Cypress, Christiana and Wealth Investments to deliver investment management and fiduciary products and services.

Change in Accumulated Other Comprehensive Income	22. CHANGE IN ACCUMULATED OTHER COMPREHENSIVE INCOME
	Accumulated other comprehensive income (loss) includes unrealized gains and losses on available-for-sale investments as well as unrecognized prior service costs, transition costs and actuarial gains and losses on defined benefit pension plans which reflects changes made to the post retirement benefit obligation for retiree health and life insurance. These changes were effective March 31, 2014 (see footnote 8 “Associate (Employee) Benefit Plans” for further information). Changes to other accumulated other comprehensive income (loss) are presented net of tax effect as a component of equity. Reclassification out of accumulated other comprehensive income is recorded on the Statements of Operations either as a gain or loss.

	Changes to accumulated other comprehensive income (loss) by component are shown net of taxes in the following tables for the period indicated:

Commitments and Contingencies Disclosure [Abstract]
Legal and Other Proceedings	23. LEGAL AND OTHER PROCEEDINGS
	As initially disclosed in 2011, we were served with a complaint, filed in U.S. Bankruptcy Court for the Eastern District of Pennsylvania, by a bankruptcy trustee relating to a former WSFS Bank customer. The complaint challenges the Bank’s actions relating to the repayment of an outstanding loan and also seeks to avoid and recover the pre-bankruptcy repayment of that loan, approximately $5.0 million. The matter has been captioned Goldstein v. Wilmington Savings Fund Society, FSB (In re: Universal Marketing, Inc.), Chapter 7, Case No. 09-15404 (ELF), Adv. Pro. No. 11-00512. We believe we acted appropriately and we are vigorously defending ourselves against the complaint.
	Based upon available information we believe the estimate of the aggregate range of reasonably possible losses for this legal proceeding was from approximately $0 to approximately $5.0 million at December 31, 2014. Costs of litigation were covered by insurance; however, such costs have now exceeded the limits of insurance coverage for this case. Cross motions for summary judgment are currently pending before the court.
	On November 25, 2014, we were served with a complaint from a vendor seeking damages of $800,000 plus attorney’s fees, due to an alleged breach of contract. The parties have agreed to mediate the dispute. We believe we acted appropriately and will vigorously defend ourselves against the complaint.
	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. Management does not anticipate that the ultimate liability, if any, arising out of such other proceedings will have a material effect on the Consolidated Financial Statements.

Subsequent Events	On March 2, 2015 we, along with Alliance Bancorp, Inc. of Pennsylvania announced the signing of a definitive agreement and plan of merger whereby the Company will acquire Alliance Bank (Alliance), the wholly-owned subsidiary of Alliance Bancorp, Inc. of Pennsylvania. Upon the closing of the transaction, Alliance will merge into WSFS Bank. Alliance is a locally-managed institution with eight branch locations headquartered in Broomall, PA. It reported approximately $421 million in assets, $310 million in loans and $345 million in deposits as of December 31, 2014. We expect this acquisition to build our market share, expand our customer base and enhance our fee income.
