Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION General Our unaudited Consolidated Financial Statements include the accounts of WSFS Financial Corporation (the Company, our Company, we, our or us), Wilmington Savings Fund Society, FSB (WSFS Bank or the Bank) and Cypress Capital Management, LLC (Cypress). We also have one unconsolidated affiliate, WSFS Capital Trust III (the Trust). WSFS Bank has three wholly-owned subsidiaries, WSFS Wealth Investments, 1832 Holdings, Inc. and Monarch Entity Services LLC (Monarch). The acronyms and abbreviations below are used in the unaudited Notes to Consolidated Financial Statements as well as in Management’s Discussion and Analysis of Financial Condition and Results of Operations.

We provide residential and commercial real estate, commercial and consumer lending services, as well as retail deposit and cash management services. Lending activities are funded primarily with customer deposits and borrowings. In addition, we offer a variety of wealth management and trust services to personal and corporate customers through our Wealth Management segment. The FDIC insures our customers’ deposits to their legal maximums. We serve our customers primarily from our 63 offices located in Delaware (44), Pennsylvania (17), Virginia (1) and Nevada (1) and through our website at www.wsfsbank.com Amounts subject to significant estimates are items such as the allowance for loan losses and reserves for lending related commitments, goodwill, intangible assets, post-retirement benefit obligations, the fair value of financial instruments, reverse mortgage loans, OTTI, and income tax valuation allowance. Among other effects, changes to such estimates could result in future impairments of investment securities, goodwill and intangible assets and establishment of the allowance and lending related commitments as well as increased post-retirement benefits expense. Our accounting and reporting policies conform to GAAP, prevailing practices within the banking industry for interim financial information and Rule 10-01 of SEC Regulation S-X (Rule 10-01). Rule 10-01 does not require us to include all information and notes that would be required in audited financial statements. Operating results for the periods presented are not necessarily indicative of the results that may be expected for any future quarters or for the year ending December 31, 2016. These unaudited, interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in our 2015 Annual Report on Form 10-K that was filed with the SEC on February 29, 2016 and is available at www.sec.gov Whenever necessary, reclassifications have been made to the prior period Consolidated Financial Statements to conform to the current period’s presentation. All significant intercompany transactions were eliminated in consolidation. The significant accounting policies used in preparation of our Consolidated Financial Statements are disclosed in our 2015 Annual Report on Form 10-K. There have not been any material changes in our significant accounting policies from those contained in our 2015 Annual Report on Form 10-K. Common Stock Split In March 2015, the Company’s Board of Directors adopted an amendment to the Company’s Certificate of Incorporation, to increase the number of shares of common stock the Company is authorized to issue from 20,000,000, par value $0.01 to 65,000,000, par value $0.01. This amendment to the Company’s Certificate of Incorporation was approved by the Company’s stockholders at the 2015 Annual Meeting held on April 30, 2015. In May 2015, the Company effected a three-for-one stock split in the form of a stock dividend to shareholders of record as of May 4, 2015. All share and per share information has been retroactively adjusted to reflect the stock split. We retroactively adjusted stockholders’ equity to reflect the stock split by reclassifying an amount equal to the par value, $0.01, of the additional shares arising from the split from capital in excess of par value to common stock, resulting in no net impact to stockholders’ equity on our Consolidated Statements of Condition. Stock-Based Compensation Stock-based compensation is accounted for in accordance with FASB ASC 718, Stock Compensation. Compensation expense relating to all share-based payments is recognized on a straight-line basis, over the applicable vesting period. Our Stock Incentive Plans provide for the granting of stock options, stock appreciation rights, performance awards, restricted stock and restricted stock unit awards, deferred stock units, and other awards that are payable in or valued by reference to our common shares. The number of shares reserved for issuance under our 2013 Incentive Plan is 2,096,535. At March 31, 2016, there were 749,825 shares available for future grants under the 2013 Incentive Plan. Stock-based compensation expense related to awards granted to Associates is recorded in salaries, benefits and other compensation; expense related to awards granted to directors is recorded in other operating expense. Total stock-based compensation expense recognized for the three months ended March 31, 2016 was $758,000 pre-tax ($430,000 after tax), or $0.01 per share. This compares to $842,000 pre-tax ($593,000 after tax), or $0.02 per share during the three months ended March 31, 2015. Stock Options Stock options are granted with an exercise price not less than the fair market value of our common stock on the date of the grant. All stock options are to be granted at not less than the market price of our common stock on the date of the grant. All stock options granted during 2016 and 2015 vest in 25% per annum increments, start to become exercisable one year from the grant date and expire seven years from the grant date. Generally, all awards become exercisable immediately in the event of a change in control, as defined within the Stock Incentive Plans. We issue new shares upon the exercise of options. We determine the grant date fair value of stock options using the Black-Scholes option-pricing model. The model requires the use of numerous assumptions, many of which are subjective. For stock options granted during 2016 we utilized our historical share option exercise experience to estimate the expected term of options. For stock options granted in 2015 we used the simplified method provided for in Staff Accounting Bulletin (SAB) Topic 14.D.2 to estimate the expected term of options as we did not believe our historical share option exercise experience was sufficient to provide a reasonable basis upon which to estimate expected term at that time. Other significant assumptions to determine 2016 and 2015 grant date fair value included volatility measured using the fluctuation in month end closing stock prices over a period which corresponds with the average expected option life; a weighted-average risk-free rate of return (zero coupon treasury yield); and a dividend yield indicative of our current dividend rate The assumptions for options issued during the three months ended 2016 and 2015 are presented below: 2016 2015 Expected term (in years) 5.3 4.9 Volatility 29.6% 25.0% Weighted-average risk-free interest rate 1.24% 1.54% Dividend yield 0.80% 0.76% The following table provides information about our stock options outstanding as of March 31, 2016: March 31, 2016 Shares Weighted- Stock Options: Outstanding at beginning of period 1,647,878 $ 17.08 Granted 67,591 29.86 Exercised (60,770 ) 15.52 Forfeited (2,622 ) 14.75 Outstanding at end of period 1,652,077 17.67 Exercisable at end of period 901,777 16.53 Weighted-average fair value of awards granted $ 7.84 The following table provides information about our nonvested stock options outstanding at March 31, 2016: March 31, 2016 Shares Weighted- Stock Options: Unvested at beginning of period 1,028,142 $ 17.58 Granted 67,591 29.86 Forfeited (1,461 ) 14.97 Vested (343,972 ) 16.83 Unvested at end of period 750,300 $ 19.03 The total amount of unrecognized compensation cost related to nonvested stock options as of March 31, 2016 was $3.2 million. The weighted-average period over which the expense is expected to be recognized is 2.2 years. Restricted Stock and Restricted Stock Units Restricted stock awards (RSAs) and restricted stock units (RSUs) are granted at no cost to the recipient and generally vest over a four year period. RSA recipients are entitled to voting rights and generally entitled to dividends on the common stock during the vesting period. The fair value of RSAs and RSUs is equal to the fair value of the Company’s common stock on the date of grant. We recognize the expense related to RSAs and RSUs granted to Associates into salaries, benefits and other compensation expense and granted to directors into other operating 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 Long-Term Performance-Based Restricted Stock Unit program (Long-Term Program) provided for awards up to an aggregate of 233,400 RSUs to 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% ROA performance level. In accordance with the Long-Term Program, the Company issued 108,456 RSUs to the plan’s participants in 2014. The RSUs vest in 25% increments over four years and we recognize expense over the implicit service period associated with the performance condition. During the first quarter of 2016, we recognized $92,000 of compensation expense related to this program. The following table summarizes the Company’s RSAs and RSUs, including performance awards, and changes during the three months ended March 31, 2016: March 31, 2016 Weighted Average Units (in whole) Grant-Date Fair Value per Unit Outstanding at beginning of period 171,834 $ 19.00 Granted 44,186 29.86 Vested (71,932 ) 16.45 Forfeited (402 ) 25.17 Outstanding at end of period 143,686 $ 23.60 The total amount of compensation cost to be recognized relating to non-vested restricted stock, including performance awards, as of March 31, 2016, was $2.9 million. The weighted-average period over which the expense is expected to be recognized is 3.0 years.

Penn Liberty is a locally managed institution with eleven branch locations and is headquartered in Wayne, Pennsylvania. It reported $704 million in assets, $510 million in loans and $621 million in deposits as of December 31, 2015. We expect this acquisition to build our market share, expand our customer base and enhance our fee income. The total transaction is valued at approximately $101 million, has received all necessary approvals and is expected to close in August 2016. Alliance Bancorp, Inc. of Pennsylvania On October 9, 2015 we completed the acquisition of Alliance and its wholly owned subsidiary, Alliance Bank, headquartered in Broomall, Pennsylvania. At that time Alliance merged into the Company and Alliance Bank merged into WSFS Bank. In accordance with the terms of the Agreement and Plan of Merger, dated March 2, 2015, holders of shares of Alliance common stock received, in aggregate, $26.6 million in cash and 2,459,120 shares of WSFS common stock. The transaction was valued at $97.9 million based on WSFS’ October 9, 2015 closing share price of $29.01 as quoted on NASDAQ. The results of the combined entity’s operations are included in our Consolidated Financial Statements since the date of the acquisition. The acquisition of Alliance 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 fair values are preliminary estimates and are subject to adjustment during the one year measurement period after the acquisition. The excess of consideration paid over the preliminary fair value of net assets acquired was recorded as goodwill in the amount of $36.1 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 $2.6 million in core deposit intangibles which are being amortized over ten years using the straight-line depreciation method and $511,000 for non-compete covenants which are being amortized between six and eighteen months. 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 (2,459,120) $ 71,345 Cash paid to Alliance stockholders 26,576 Value of consideration 97,921 Assets acquired: Cash and due from banks 67,439 Investment securities 3,002 Loans 307,695 Premises and equipment 2,685 Deferred income taxes 7,730 Bank owned life insurance 12,923 Core deposit intangible 2,635 Other real estate owned 768 Other assets 3,583 Total assets 408,460 Liabilities assumed: Deposits 341,682 Other Borrowings 2,826 Other liabilities 2,098 Total liabilities 346,606 Net assets acquired: 61,854 Goodwill resulting from acquisition of Alliance $ 36,067 The following table details the changes to goodwill in 2016: (In Thousands) Fair Value Goodwill resulting from the acquisition of Alliance reported as of December 31, 2015 $ 36,425 Effects of adjustments to: Deferred income taxes (186 ) Other assets (597 ) Other liabilities 425 Adjusted goodwill resulting from the acquisition of Alliance as of March 31, 2016 $ 36,067 The adjustments made to goodwill during the first three months of 2016, reflect a change in the fair value of leases acquired, accrued expenses and deferred federal income taxes. Direct costs related to the acquisition were expensed as incurred. During the three months ended March 31, 2016, the Company incurred $426,000 in merger expenses related to Alliance and Penn Liberty compared to $666,000 for the three months ended March 31, 2015.

Investment securities with fair market values aggregating $423.8 million and $457.0 million were pledged as collateral for retail customer repurchase agreements, municipal deposits, and other obligations as of March 31, 2016 and December 31, 2015, respectively. During the first three months of 2016 and 2015, we sold $38.9 million and $37.4 million of investment securities categorized as available-for-sale, for a gain of $305,000 and $451,000, respectively. No losses were incurred from sales during the first three months of 2016 and 2015. As of March 31, 2016 and December 31, 2015, our investment securities portfolio had remaining unamortized premiums of $18.7 million and $18.3 million and unaccreted discounts of $307,000 and $306,000, respectively.

Total unrealized losses on these securities were $372,000 at March 31, 2016. 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 OTTI. This review includes analyzing the length of time and the extent to which the fair value has been lower than the amortized cost, the financial condition and near-term prospects of the issuer, including any specific events which may influence the operations of the issuer and our intent and ability to hold the investment for a period of time sufficient to allow for full recovery of the unrealized loss. We evaluate our intent and ability to hold 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. All securities, with the exception of one, were AA-rated or better at the time of purchase and remained investment grade at March 31, 2016. All securities were evaluated for OTTI at March 31, 2016 and December 31, 2015. The result of this evaluation showed no OTTI as of March 31, 2016 or December 31, 2015. The estimated weighted average duration of MBS was 4.1 years at March 31, 2016.

Allowance for Loan Losses and Credit Quality Information	6. ALLOWANCE FOR LOAN LOSSES AND CREDIT QUALITY INFORMATION Allowance for Loan Losses We maintain an allowance for loan losses and charge losses to this allowance when such losses are realized. We established our allowance for loan losses in accordance with guidance provided in the SEC’s Staff Accounting Bulletin 102 (SAB 102) and FASB ASC 450, Contingencies • Specific reserves for impaired loans • An allowance for each pool of homogenous loans based on historical 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. We charge loans off when they are deemed to be uncollectible. During the three months ended March 31, 2016, net charge-offs totaled $313,000 or 0.03% of average loans, compared to $705,000, or 0.09% of average loans annualized, during the three months ended March 31, 2015. 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 21 quarters. During the three months ended March 31 2016, we increased the look-back period to 21 quarters from the 20 quarters used at December 31, 2015. This increase in the look-back period allows us to continue to anchor to the fourth quarter of 2010 to ensure that the core reserves calculated by the ALLL model are adequately considering the losses within a full credit cycle. Loss severity upon default is calculated as the actual loan losses (net of recoveries) on impaired loans in their respective pool during the same time frame. Retail loans are pooled into the following segments: residential mortgage, consumer secured and consumer unsecured loans. Pooled reserves for retail loans are calculated based solely on average net loss rates over the same 21 quarter look-back period. Qualitative adjustment factors consider various current internal and external conditions which are allocated among loan types and take into consideration the following: • Current underwriting policies, staff, and portfolio mix • Internal trends of delinquency, nonaccrual and criticized loans by segment • Risk rating accuracy, control and regulatory assessments/environment • General economic conditions - locally and nationally • Market trends impacting collateral values • A competitive environment as it could impact loan structure and underwriting The above factors are based on their relative standing compared to the period in which historic losses are used in core reserve estimates and current directional trends. Qualitative factors in our model can add or subtract to core reserves. Continued economic improvement and continued refinement of the quantitative model have driven an overall reduction in qualitative factors during the period. The allowance methodology uses a loss emergence period (LEP), which is the period of time between an event that triggers the probability of a loss and the confirmation of the loss. We estimate the commercial LEP to be 8 quarters as of March 31, 2016. Further, our residential mortgage and consumer LEP remained at 4 quarters as of March 31, 2016. We evaluate LEP quarterly for reasonableness and complete a detailed historical analysis of our commercial LEP at least annually. The final component of the allowance is a reserve for model estimation and complexity risk. The calculation of this reserve is generally quantitative; however, qualitative estimates of valuations and risk assessment, and methodology judgments are necessary in order to capture factors not already included in other components in our allowance for loan losses methodology. We review the qualitative estimates of valuation factors quarterly and management uses its judgment to make adjustments based on current trends. Our loan officers and risk managers meet at least quarterly to discuss and review the conditions and risks associated with individual problem loans. In addition, various regulatory agencies periodically review our loan ratings and allowance for loan losses and the Bank’s internal loan review department performs loan reviews.

(2) The difference between this amount and nonaccruing loans represents accruing troubled debt restructured loans of $13.9 million and $22.5 million for the periods ending March 31, 2016 and 2015, respectively. Accruing troubled debt restructured loans are considered impaired loans. (3) Ending loan balances do not include deferred costs. Nonaccrual 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.

Interest income of $156,000, and $472,000 was recognized on impaired loans during the three months ended March 31, 2016 and 2015, respectively. As of March 31, 2016, there were 40 residential loans and 7 commercial loans in the process of foreclosure. The total outstanding balance on the loans was $6.3 million and $667,000, respectively. As of December 31, 2015, there were 32 residential loans and 3 commercial loans in the process of foreclosure. The total outstanding balance on the loans was $5.0 million and $675,000, respectively. Reserves on Acquired Nonimpaired Loans In accordance with FASB ASC 310, loans acquired by the Bank through its merger with FNBW and Alliance are required to be reflected on the balance sheet at their fair values on the date of acquisition as opposed to their contractual values. Therefore, on the date of acquisition establishing an allowance for acquired loans is prohibited. After the acquisition date the Bank performs a separate allowance analysis on a quarterly basis to determine if an allowance for loan loss is necessary. Should the credit risk calculated exceed the purchased loan portfolio’s remaining credit mark, additional reserves will be added to the Bank’s allowance. When a purchased loan becomes impaired after its acquisition, it is evaluated as part of the Bank’s reserve analysis and a specific reserve is established to be included in the Bank’s allowance. Credit Quality Indicators Below is a description of each of our risk ratings for all commercial loans: Pass Special Mention. Substandard. Doubtful. Loss. Residential and Consumer Loans The residential and consumer loan portfolios are monitored on an ongoing basis using delinquency information and loan type as credit quality indicators. These credit quality indicators are assessed in the aggregate in these relatively homogeneous portfolios. Loans that are greater than 90 days past due are generally considered nonperforming and placed on nonaccrual status.

Troubled Debt Restructurings (TDR) TDRs are recorded in accordance with FASB ASC 310-40, Troubled Debt Restructuring by Creditors (ASC 310-40) During the three months ended March 31, 2016, the terms of 8 loans were modified in TDRs. Five modifications were for consumer loans of which all were HELOC conversions with interest rate reductions. Two were residential mortgages of which both were forbearance agreements. One commercial loan in bankruptcy was granted interest only payments. Our concessions on restructured loans typically consist of forbearance agreements, reduction in interest rates or extensions of maturities. Principal balances are generally not forgiven when a loan is modified as a TDR. Nonaccruing restructured loans remain in nonaccrual status until there has been a period of sustained repayment performance, typically six months and payment is reasonably assured.

Reverse Mortgage Loans

Mortgage Banking [Abstract]
Reverse Mortgage Loans	7. REVERSE MORTGAGE LOANS 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. Our investment in reverse mortgages totaled $24.7 million at March 31, 2016. The portfolio consists of 90 loans with an average borrowers’ age of 94 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 $45.6 million exceeds the outstanding book balance at March 31, 2016. Broker price opinions are updated at least annually. Additional broker price opinions are obtained when our quarterly review indicates that a home’s value has increased or decreased by at least 50% during any given period. The carrying value of the reverse mortgages is calculated using a proprietary model that uses the income approach as described in FASB ASC 820-10, Fair Value Measurements and Disclosure To determine the carrying value of these reverse mortgages as of March 31, 2016, we used the proprietary model described above 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 – We used the actuarial estimates of contract termination provided in the United States Mortality Rates Period Life Table, 2011, published by the Office of the Actuary - Social Security in 2015, adjusted for expected prepayments and relocations which we adopted during 2016. 2) House Price Appreciation – We utilize house price forecasts from various market sources. Based on this information, we forecasted a 2.5% increase in housing prices during 2016 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, current collateral values are updated through broker price opinions. 3) Internal Rate of Return – As of March 31, 2016, the internal rate of return (IRR) of 19.32% 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 March 31, 2016, the Company’s actuarially estimated cash payments to reverse mortgagors are as follows: (In thousands) Year Ending 2016 $ 580 2017 435 2018 342 2019 266 2020 204 Years 2021 - 2025 466 Years 2026 - 2030 92 Years 2031 - 2035 13 Thereafter 2 Total (1) $ 2,400 (1) 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 we were not to make cash payments to reverse mortgagors in the future is $6.2 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 $745,000 for the quarter ended March 31, 2016 with an IRR of 18.41%. If the future changes in collateral value were assumed to be reduced by 1%, income would decrease by $343,000 with an IRR of 18.90%. The net present value of the projected cash flows depends on the IRR used. If the IRR increased by 1%, the net present value would increase by $984,000. If the IRR decreased by 1%, the net present value would decrease by $957,000.

INCOME TAXES We account for income taxes in accordance with FASB ASC 740, Income Taxes ASC 740 prescribes a minimum probability threshold that a tax position must meet before a financial statement benefit is recognized. We recognize, when applicable, interest and penalties related to unrecognized tax benefits in the provision for income taxes in the financial statements. Assessment of uncertain tax positions under ASC 740 requires careful consideration of the technical merits of a position based on our analysis of tax regulations and interpretations. There were no unrecognized tax benefits as of March 31, 2016. We record interest and penalties on potential income tax deficiencies as income tax expense. Our federal and state tax returns for the 2012 through 2015 tax years are subject to examination as of March 31, 2016. Pennsylvania is currently auditing our 2012 state tax return. We do not expect to record or realize any material unrecognized tax benefits during 2016. As a result of the adoption of ASU No. 2014-01, “ Investments-Equity Method and Joint Ventures: Accounting for Investments in Qualified Affordable Housing Projects The amount of affordable housing tax credits, amortization and tax benefits recorded as income tax expense for the three months ended March 31, 2016 were $368,000, $390,000 and $89,000, respectively. The carrying value of the investment in affordable housing credits is $11.6 million at March 31, 2016, compared to $12.0 million at December 31, 2015.

Fair Value Disclosures [Abstract]
Fair Value Disclosures of Financial Assets and Liabilities	11. FAIR VALUE DISCLOSURES OF FINANCIAL ASSETS AND LIABILITIES FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES ASC 820-10 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820-10 establishes a fair value hierarchy that prioritizes the use of inputs used in valuation methodologies into the following three levels: Level 1: Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available. Level 2: Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets; inputs to the valuation methodology include quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs to the valuation methodology that are derived principally from or can be corroborated by observable market data by correlation or other means. Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Level 3 assets and liabilities include financial instruments whose value is determined using discounted cash flow methodologies, as well as instruments for which the determination of fair value requires significant management judgment or estimation. The following tables present financial instruments carried at fair value as of March 31, 2016 and December 31, 2015 by valuation hierarchy (as described above): (In Thousands) Description Quoted Significant Significant Total Fair Assets measured at fair value on a recurring basis Available-for-sale securities: CMO $ — $ 273,902 $ — $ 273,902 FNMA MBS — 341,623 — 341,623 FHLMC MBS — 100,918 — 100,918 GNMA MBS — 19,111 — 19,111 GSE — 39,158 — 39,158 Total assets measured at fair value on a recurring basis $ — $ 774,712 $ — $ 774,712 Assets measured at fair value on a nonrecurring basis Other real estate owned $ — $ — $ 3,979 $ 3,979 Loans held-for-sale — 36,178 — 36,178 Impaired loans — — 33,701 33,701 Total assets measured at fair value on a nonrecurring basis $ — $ 36,178 $ 37,680 $ 73,858 (In Thousands) Description Quoted Significant Significant Total Assets measured at fair value on a recurring basis Available-for-sale securities: CMO $ — $ 251,488 $ — $ 251,488 FNMA MBS — 318,471 — 318,471 FHLMC MBS — 99,442 — 99,442 GNMA MBA — 20,714 — 20,714 GSE 30,914 — 30,914 Total assets measured at fair value on a recurring basis $ — $ 721,029 $ — $ 721,029 Assets measured at fair value on a nonrecurring basis Other real estate owned $ — $ — $ 5,080 $ 5,080 Loans held-for sale — 41,807 — 41,807 Impaired loans (collateral dependent) — — 35,086 35,086 Total assets measured at fair value on a nonrecurring basis $ — $ 41,807 $ 40,166 $ 81,973 There were no transfers between Level 1 and Level 2 of the fair value hierarchy during the three months ending March 31, 2016 and no material liabilities measured at fair value as of March 31, 2016 and December 31, 2015. 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 March 31, 2016 securities classified as available-for-sale are reported at fair value using Level 2 inputs. Included in the Level 2 total are approximately $39.2 million in U.S. Treasury Notes and Federal Agency debentures, and $735.6 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 The fair value of our loans held-for-sale is based upon estimates using Level 2 inputs. These inputs are based upon pricing information obtained from secondary markets and brokers and applied to loans with similar interest rates and maturities. Impaired loans We evaluate and value impaired loans at the time the loan is identified as impaired, and the fair values of such loans are estimated using Level 3 inputs in the fair value hierarchy. Each loan’s collateral has a unique appraisal and management’s discount of the value is based on the factors unique to each impaired loan. The significant unobservable input in determining the fair value is management’s subjective discount on appraisals of the collateral securing the loan, which 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 $36.6 million and $37.7 million at March 31, 2016 and December 31, 2015, respectively. The valuation allowance on impaired loans was $2.9 million as of March 31, 2016 and $2.6 million as of December 31, 2015. FAIR VALUE OF FINANCIAL INSTRUMENTS The reported fair values of financial instruments are based on a variety of factors. In certain cases, fair values represent quoted market prices for identical or comparable instruments. In other cases, fair values have been estimated based on assumptions regarding the amount and timing of estimated future cash flows that are discounted to reflect current market rates and varying degrees of risk. Accordingly, the fair values may not represent actual values of the financial instruments that could have been realized as of period-end or that will be realized in the future. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: Cash and cash equivalents For cash and short-term investment securities, including due from banks, federal funds sold or purchased under agreements to resell and interest-bearing deposits with other banks, the carrying amount is a reasonable estimate of fair value. Investment securities Fair value is estimated using quoted prices for similar securities, which we obtain from a third party vendor. We utilize one of the largest providers of securities pricing to the industry and management periodically assesses the inputs used by this vendor to price the various types of securities owned by us to validate the vendor’s methodology. Loans held-for sale Loans held-for- sale are carried at their fair value (see discussion earlier in the note). 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 loans 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 information on reverse mortgage loans, see Note 7, Reverse Mortgage Loans, to the unaudited Consolidated Financial Statements. Stock in the Federal Home Loan Bank (FHLB) of Pittsburgh The fair value of FHLB stock is assumed to be equal to its cost basis, since the stock is non-marketable but redeemable at its par value. Other assets Other assets includes other real estate owned (see discussion earlier in this note) and our investment in Visa Class B stock. Our ownership includes shares acquired at no cost from our prior participation in Visa’s network, while Visa operated as a cooperative. During 2015 we purchased additional shares which are accounted for as non-marketable equity securities and carried at cost. We evaluated the shares carried at cost for OTTI as of March 31, 2016, and the evaluation showed no OTTI as of March 31, 2016. Following resolution of Visa’s covered litigation, shares of Visa’s Class B stock will be converted to Visa Class A shares 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 $13.1 million as of March 31, 2016. 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. The book value and estimated fair value of our financial instruments are as follows: Fair Value March 31, 2016 December 31, 2015 (In Thousands) Measurement Book Value Fair Value Book Value Fair Value Financial assets: Cash and cash equivalents Level 1 $ 590,028 590,028 $ 561,179 $ 561,179 Investment securities available-for-sale Level 2 774,712 774,712 721,029 721,029 Investment securities held-to-maturity Level 2 166,962 170,540 165,862 167,743 Loans, held-for-sale Level 2 36,178 36,178 41,807 41,807 Loans, net (1) Level 2 3,724,028 3,685,174 3,693,964 3,637,714 Impaired loans, net Level 3 33,701 33,701 35,086 35,086 Reverse mortgage loans Level 3 24,739 24,739 24,284 24,284 Stock in FHLB of Pittsburgh Level 2 30,711 30,444 30,519 30,519 Accrued interest receivable Level 2 13,992 13,992 14,040 14,040 Other assets Level 3 7,568 17,123 8,669 18,416 Financial liabilities: Deposits Level 2 4,068,771 3,890,594 4,016,566 3,791,606 Borrowed funds Level 2 971,264 973,805 932,886 933,905 Standby letters of credit Level 3 204 204 195 195 Accrued interest payable Level 2 1,340 1,340 801 801 (1) At March 31, 2016 and December 31, 2015 we had no commitments to extend credit measured at fair value.

Segment Reporting [Abstract]
Segment Information	12. SEGMENT INFORMATION In accordance with FASB ASC 280, Segment Reporting The WSFS Bank segment provides financial products to commercial and retail customers. Retail and Commercial Banking, Commercial Real Estate Lending and other banking business units are operating departments of WSFS. 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 ATM vault cash and smart safe and cash logistics 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 Wealth Management segment provides a broad array of fiduciary, investment management, credit and deposit products to clients through four business lines. WSFS Wealth Investments provides insurance and brokerage products primarily to our retail banking clients. Cypress Capital Management, LLC is a registered investment advisor. Cypress’ primary market segment is high net worth individuals, offering a ‘balanced’ investment style focused on preservation of capital and current income. Christiana Trust provides fiduciary and investment services to personal trust clients, and trustee, agency, bankruptcy administration, 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 other business units to deliver investment management and fiduciary products and services.

Indemnifications and Guarantees	13. INDEMNIFICATIONS AND GUARANTEES 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 GSEs such as FHLMC, FNMA, and the FHLB. Loans held-for-sale are reflected on our unaudited Consolidated Statements of Condition at fair value with changes in the value reflected in our unaudited Consolidated Statements of Cash Flows and Comprehensive Income. 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 intangible assets in our unaudited Consolidated Statements of Condition. Otherwise, we sell loans with servicing released on a nonrecourse basis. Rate-locked loan commitments that we intend to sell in the secondary market are accounted for as derivatives under the guidance promulgated in FASB ASC Topic 815, Derivatives and Hedging 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 no such repurchases for the three months ended March 31, 2016. Swap Guarantees. We entered into agreements with five unrelated financial institutions whereby those financial institutions entered into interest rate derivative contracts (interest rate swap transactions) with customers referred to them by us. 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 ASC 815 . At March 31, 2016 there were 123 variable-rate to fixed-rate swap transactions between the third party financial institutions and our customers, compared to 119 at December 31, 2015. The initial notional aggregated amount was approximately $488.9 million at March 31, 2016 compared to $481.6 million at December 31, 2015. At March 31, 2016 maturities ranged from four months to over 10 years. The aggregate market value of these swaps to the customers was a liability of $27.0 million at March 31, 2016 and $18.1 million at December 31, 2015. There were no reserves for the swap guarantees as of March 31, 2016.

Commitments and Contingencies Disclosure [Abstract]
Legal and Other Proceedings	15. LEGAL AND OTHER PROCEEDINGS As initially disclosed in 2011, we were served with a complaint, filed in the 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. On November 24, 2015 the Court entered summary judgment in favor of WSFS Bank on all but one of the remaining counts, leaving one count for resolution at trial. Based upon available information we believe the estimate of the aggregate range of reasonably possible losses for this legal proceeding is from approximately $0 to approximately $5.0 million at March 31, 2016. Costs of litigation were initially covered by insurance; however, such costs have now exceeded the limits of insurance coverage for this case. Four purported shareholder derivative and class action complaints relating to the October 2015 merger with Alliance were filed during the quarter ended June 30, 2015. These actions were consolidated under the caption In re: Alliance Bancorp, Inc. of Pennsylvania Derivative and Class Action Litigation, Court of Common Pleas of Delaware County, Pennsylvania, Consol. Action Lead Case No. 2015-3606 (Civil Div.) (the Alliance Action). The complaint named as defendants Alliance Bancorp, Inc. of Pennsylvania, its directors and certain of its officers, and the Company (the Defendants). As previously disclosed, on June 11, 2015, solely to avoid the costs, risks and uncertainties inherent in litigation, Alliance, WSFS and the other Defendants entered into a Memorandum of Understanding (the MOU) with the plaintiffs ( the Plaintiffs) regarding the settlement of the Alliance Action. Pursuant to the MOU, Alliance filed with the SEC and made publicly available to Alliance shareholders supplemental disclosures, and the Plaintiffs agreed to release Alliance, WSFS and the other Defendants from all claims related to the Merger Agreement and the proposed merger, subject to approval of the Court of Common Pleas of Delaware County (the Court). In the MOU, the parties agreed to negotiate in good faith to prepare a stipulation of settlement to be filed with the Court and other documentation as may be required to effectuate the settlement. Management does not expect this settlement to have a material impact on the Company’s Consolidated Statements of Operations or Consolidated Statements of Condition. There can be no assurance that the parties ultimately will enter into a stipulation of settlement or that the Court will approve the settlement even if the parties were to enter into such stipulation. The proposed settlement contemplated by the MOU will become void in the event that the parties do not enter into such stipulation or the Court does not approve the settlement. Additionally, in 2013 a regulatory inquiry commenced into the registered transfer agent (“RTA”) activities of WSFS, as successor to Christiana Bank & Trust. As a result of issues arising from that inquiry, WSFS revamped Christiana Trust’s RTA policies and procedures and remediated all deficiencies. We have included the estimated financial liability from the expected resolution of this inquiry, which is not material, in our Consolidated Financial Statements as of March 31, 2016. From time-to-time we are brought into certain legal matters and/or disputes through our Wealth Management segment, as a result of sometimes highly complex documents and servicing requirements that are part of this business. While the outcomes carry some degree of uncertainty, management does not currently anticipate that the ultimate liability, if any, arising out of such other proceedings we are aware of, will have a material effect on the Consolidated Financial Statements. 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.

We provide residential and commercial real estate, commercial and consumer lending services, as well as retail deposit and cash management services. Lending activities are funded primarily with customer deposits and borrowings. In addition, we offer a variety of wealth management and trust services to personal and corporate customers through our Wealth Management segment. The FDIC insures our customers’ deposits to their legal maximums. We serve our customers primarily from our 63 offices located in Delaware (44), Pennsylvania (17), Virginia (1) and Nevada (1) and through our website at www.wsfsbank.com Amounts subject to significant estimates are items such as the allowance for loan losses and reserves for lending related commitments, goodwill, intangible assets, post-retirement benefit obligations, the fair value of financial instruments, reverse mortgage loans, OTTI, and income tax valuation allowance. Among other effects, changes to such estimates could result in future impairments of investment securities, goodwill and intangible assets and establishment of the allowance and lending related commitments as well as increased post-retirement benefits expense. Our accounting and reporting policies conform to GAAP, prevailing practices within the banking industry for interim financial information and Rule 10-01 of SEC Regulation S-X (Rule 10-01). Rule 10-01 does not require us to include all information and notes that would be required in audited financial statements. Operating results for the periods presented are not necessarily indicative of the results that may be expected for any future quarters or for the year ending December 31, 2016. These unaudited, interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in our 2015 Annual Report on Form 10-K that was filed with the SEC on February 29, 2016 and is available at www.sec.gov Whenever necessary, reclassifications have been made to the prior period Consolidated Financial Statements to conform to the current period’s presentation. All significant intercompany transactions were eliminated in consolidation. The significant accounting policies used in preparation of our Consolidated Financial Statements are disclosed in our 2015 Annual Report on Form 10-K. There have not been any material changes in our significant accounting policies from those contained in our 2015 Annual Report on Form 10-K.
Common Stock Split	Common Stock Split In March 2015, the Company’s Board of Directors adopted an amendment to the Company’s Certificate of Incorporation, to increase the number of shares of common stock the Company is authorized to issue from 20,000,000, par value $0.01 to 65,000,000, par value $0.01. This amendment to the Company’s Certificate of Incorporation was approved by the Company’s stockholders at the 2015 Annual Meeting held on April 30, 2015. In May 2015, the Company effected a three-for-one stock split in the form of a stock dividend to shareholders of record as of May 4, 2015. All share and per share information has been retroactively adjusted to reflect the stock split. We retroactively adjusted stockholders’ equity to reflect the stock split by reclassifying an amount equal to the par value, $0.01, of the additional shares arising from the split from capital in excess of par value to common stock, resulting in no net impact to stockholders’ equity on our Consolidated Statements of Condition.
Stock-Based Compensation	Stock-Based Compensation Stock-based compensation is accounted for in accordance with FASB ASC 718, Stock Compensation. Compensation expense relating to all share-based payments is recognized on a straight-line basis, over the applicable vesting period. Our Stock Incentive Plans provide for the granting of stock options, stock appreciation rights, performance awards, restricted stock and restricted stock unit awards, deferred stock units, and other awards that are payable in or valued by reference to our common shares. The number of shares reserved for issuance under our 2013 Incentive Plan is 2,096,535. At March 31, 2016, there were 749,825 shares available for future grants under the 2013 Incentive Plan. Stock-based compensation expense related to awards granted to Associates is recorded in salaries, benefits and other compensation; expense related to awards granted to directors is recorded in other operating expense. Total stock-based compensation expense recognized for the three months ended March 31, 2016 was $758,000 pre-tax ($430,000 after tax), or $0.01 per share. This compares to $842,000 pre-tax ($593,000 after tax), or $0.02 per share during the three months ended March 31, 2015. Stock Options Stock options are granted with an exercise price not less than the fair market value of our common stock on the date of the grant. All stock options are to be granted at not less than the market price of our common stock on the date of the grant. All stock options granted during 2016 and 2015 vest in 25% per annum increments, start to become exercisable one year from the grant date and expire seven years from the grant date. Generally, all awards become exercisable immediately in the event of a change in control, as defined within the Stock Incentive Plans. We issue new shares upon the exercise of options. We determine the grant date fair value of stock options using the Black-Scholes option-pricing model. The model requires the use of numerous assumptions, many of which are subjective. For stock options granted during 2016 we utilized our historical share option exercise experience to estimate the expected term of options. For stock options granted in 2015 we used the simplified method provided for in Staff Accounting Bulletin (SAB) Topic 14.D.2 to estimate the expected term of options as we did not believe our historical share option exercise experience was sufficient to provide a reasonable basis upon which to estimate expected term at that time. Other significant assumptions to determine 2016 and 2015 grant date fair value included volatility measured using the fluctuation in month end closing stock prices over a period which corresponds with the average expected option life; a weighted-average risk-free rate of return (zero coupon treasury yield); and a dividend yield indicative of our current dividend rate The assumptions for options issued during the three months ended 2016 and 2015 are presented below: 2016 2015 Expected term (in years) 5.3 4.9 Volatility 29.6% 25.0% Weighted-average risk-free interest rate 1.24% 1.54% Dividend yield 0.80% 0.76% The following table provides information about our stock options outstanding as of March 31, 2016: March 31, 2016 Shares Weighted- Stock Options: Outstanding at beginning of period 1,647,878 $ 17.08 Granted 67,591 29.86 Exercised (60,770 ) 15.52 Forfeited (2,622 ) 14.75 Outstanding at end of period 1,652,077 17.67 Exercisable at end of period 901,777 16.53 Weighted-average fair value of awards granted $ 7.84 The following table provides information about our nonvested stock options outstanding at March 31, 2016: March 31, 2016 Shares Weighted- Stock Options: Unvested at beginning of period 1,028,142 $ 17.58 Granted 67,591 29.86 Forfeited (1,461 ) 14.97 Vested (343,972 ) 16.83 Unvested at end of period 750,300 $ 19.03 The total amount of unrecognized compensation cost related to nonvested stock options as of March 31, 2016 was $3.2 million. The weighted-average period over which the expense is expected to be recognized is 2.2 years. Restricted Stock and Restricted Stock Units Restricted stock awards (RSAs) and restricted stock units (RSUs) are granted at no cost to the recipient and generally vest over a four year period. RSA recipients are entitled to voting rights and generally entitled to dividends on the common stock during the vesting period. The fair value of RSAs and RSUs is equal to the fair value of the Company’s common stock on the date of grant. We recognize the expense related to RSAs and RSUs granted to Associates into salaries, benefits and other compensation expense and granted to directors into other operating 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 Long-Term Performance-Based Restricted Stock Unit program (Long-Term Program) provided for awards up to an aggregate of 233,400 RSUs to 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% ROA performance level. In accordance with the Long-Term Program, the Company issued 108,456 RSUs to the plan’s participants in 2014. The RSUs vest in 25% increments over four years and we recognize expense over the implicit service period associated with the performance condition. During the first quarter of 2016, we recognized $92,000 of compensation expense related to this program. The following table summarizes the Company’s RSAs and RSUs, including performance awards, and changes during the three months ended March 31, 2016: March 31, 2016 Weighted Average Units (in whole) Grant-Date Fair Value per Unit Outstanding at beginning of period 171,834 $ 19.00 Granted 44,186 29.86 Vested (71,932 ) 16.45 Forfeited (402 ) 25.17 Outstanding at end of period 143,686 $ 23.60 The total amount of compensation cost to be recognized relating to non-vested restricted stock, including performance awards, as of March 31, 2016, was $2.9 million. The weighted-average period over which the expense is expected to be recognized is 3.0 years.
