The acronyms and abbreviations below are used in the unaudited Notes to The 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. The FDIC insures our customers’ deposits to their legal maximums. We serve our customers primarily from our 76 offices located in Delaware (46), Pennsylvania (28), Virginia (1) and Nevada (1) and through our website at www.wsfsbank.com Amounts subject to significant estimates include 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 these 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. Senior Unsecured Debt On June 13, 2016, the Company issued $100 million of senior unsecured fixed-to-floating rate notes. The senior unsecured notes mature on June 15, 2026 and have a fixed coupon rate of 4.50% from issuance until June 15, 2021 and a variable coupon rate of three-month LIBOR plus 3.30% from June 15, 2021 until maturity. The senior unsecured notes may be redeemed beginning on June 15, 2021 at 100% of principal plus accrued and unpaid interest. The proceeds will be used for general corporate purposes. Acquisitions On August 12, 2016 we completed the acquisition of Penn Liberty Financial Corp. (Penn Liberty), a community bank headquartered in Wayne, Pennsylvania. We expect this acquisition to build our market share, deepen our presence in the southeastern Pennsylvania market, and enhance our customer base. The results of Penn Liberty’s operations are included in our Consolidated Financial Statements since the date of the acquisition. See Note 2 – Business Combinations for further information. Also during the third quarter, we acquired the assets of Powdermill Financial Solutions LLC (Powdermill), a multi-family office serving an affluent clientele in the local community and throughout the United States. This acquisition aligns with our strategic plan to expand our wealth management offerings and to diversify our fee-income generating businesses. Derivatives and Hedging During the third quarter of 2016, we implemented a hedging program to manage our interest rate risk. This program did not have a material effect on our statements of condition or results of operations.

Business Combinations [Abstract]
Business Combinations	2. BUSINESS COMBINATIONS Penn Liberty Financial Corporation On August 12, 2016, we completed the acquisition of Penn Liberty. Penn Liberty conducted its primary business operations through its subsidiary Penn Liberty Bank, which was merged into WSFS Bank. Upon closing the transaction, Penn Liberty had 11 banking offices in Montgomery and Chester counties, Pennsylvania, which are suburbs of Philadelphia. WSFS acquired Penn Liberty to expand the scale and efficiency of its operations in southeastern Pennsylvania in addition to the opportunity of generating additional revenue by providing its full suite of banking, mortgage banking, wealth management and insurance services to the Penn Liberty markets. The acquisition of Penn Liberty 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. We are currently evaluating the fair values of replacement equity awards, fixed assets acquired and leases assumed in the transaction. The excess of consideration paid over the preliminary fair value of net assets acquired was recorded as goodwill in the amount of $65.2 million, which is not 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 $2.9 million in core deposit intangibles which are being amortized over ten years using the straight-line depreciation method. 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: (Dollars in thousands) Fair Value Consideration Paid: Common shares issued (1,806,748) $ 66,759 Cash paid to Penn Liberty stock and option holders 40,549 Value of consideration 107,308 Assets acquired: Cash and due from banks 102,301 Investment securities 627 Loans 483,482 Premises and equipment 7,364 Deferred income taxes 6,452 Bank owned life insurance 8,666 Core deposit intangible 2,882 Other real estate owned 996 Other assets 10,595 Total assets 623,365 Liabilities assumed: Deposits 568,706 Other borrowings 10,000 Other liabilities 2,557 Total liabilities 581,263 Net assets acquired: 42,102 Goodwill resulting from acquisition of Penn Liberty $ 65,206 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 and loss severity, along with estimated prepayment rates. Non-impaired acquired loans had a gross contractual balance of $491.2 million and a fair value of $470.8 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 $15.3 million with a fair value of $12.7 million. For additional information regarding acquired impaired loans, see Note 5 - Loans. 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. Direct costs related to the acquisition were expensed as incurred. During the three months ended September 30, 2016, the Company incurred $5.7 million in integration expenses, including $2.0 million in salary and benefits, $1.1 million in professional fees, $0.9 in data processing expense and $0.8 in marketing expense. Powdermill Financial Solutions LLC On August 1, 2016, we acquired the assets of Powdermill, a multi-family office serving an affluent clientele in the local community and throughout the United States. This acquisition aligns with our strategic plan to expand our wealth offerings and diversify our fee-income generating business. The excess of consideration paid over the preliminary fair value of the net assets acquired was recorded as goodwill, which is not amortizable but is deductible for tax purposes. The Company allocated the total balance of goodwill to its Wealth Management segment. 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 The Nasdaq Global Select Market. 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 excess of consideration paid over the fair value of net assets acquired was recorded as goodwill in the amount of $36.4 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 $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, are summarized in the following table: (Dollars 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 7,669 Bank owned life insurance 12,923 Core deposit intangible 2,635 Other real estate owned 768 Other assets 3,365 Total assets 408,181 Liabilities assumed: Deposits 341,682 Other Borrowings 2,826 Other liabilities 681 Total liabilities 345,189 Net assets acquired: 62,992 Goodwill resulting from acquisition of Alliance $ 34,929 The following table details the changes to goodwill in 2016: (Dollars 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 (125 ) Other assets (379 ) Other liabilities (992 ) Adjusted goodwill resulting from the acquisition of Alliance as of September 30, 2016 $ 34,929 The adjustments made to goodwill during the first nine months of 2016 reflect changes in the fair value of deferred federal income taxes, other assets, and other liabilities during the measurement period.

The amortized cost of held-to-maturity securities included net unrealized gains of $2.4 million and $2.9 million at September 30, 2016 and December 31, 2015, respectively, related to securities transferred, which are offset in Accumulated Other Comprehensive Income, net of tax. The scheduled maturities of investment securities available-for-sale and held-to-maturity at September 30, 2016 and December 31, 2015 are presented in the table below: Available-for-Sale (1) Amortized Fair (Dollars in thousands) Cost Value September 30, 2016 Within one year $ 8,995 $ 9,010 After one year but within five years 26,075 26,125 After five years but within ten years 281,237 289,917 After ten years 443,024 452,156 $ 759,331 $ 777,208 December 31, 2015 Within one year $ 3,997 $ 3,995 After one year but within five years 30,009 29,840 After five years but within ten years 218,023 215,018 After ten years 472,043 472,176 $ 724,072 $ 721,029 Held-to-Maturity Amortized Fair (Dollars in thousands) Cost Value September 30, 2016 Within one year $ — $ — After one year but within five years 5,097 5,180 After five years but within ten years 9,030 9,219 After ten years 150,753 155,163 $ 164,880 $ 169,562 December 31, 2015 Within one year $ 1,486 $ 1,488 After one year but within five years 3,465 3,456 After five years but within ten years 7,939 8,045 After ten years 152,972 154,754 $ 165,862 $ 167,743 (1) Included in the investment portfolio, but not in the table above, is a mutual fund with an amortized cost and fair value, as of September 30, 2016 of $0.6 million, which has no stated maturity. 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 $598.9 million and $457.0 million were pledged as collateral for retail customer repurchase agreements, municipal deposits, and other obligations as of September 30, 2016 and December 31, 2015, respectively. During the first nine months of 2016 and 2015, we sold $155.8 million and $117.3 million, respectively of investment securities categorized as available-for-sale, for a gain of $1.9 million and $1.0 million, respectively. No losses were incurred from sales during the first nine months of 2016 and 2015. As of September 30, 2016 and December 31, 2015, our investment securities portfolio had remaining unamortized premiums of $18.5 million and $18.3 million, respectively, and unaccreted discounts of $0.3 million at both September 30, 2016 and December 31, 2015. For those investment securities with unrealized losses, the table below shows our gross unrealized losses and fair value by investment category and length of time that individual securities were in a continuous unrealized loss position at September 30, 2016.

Total unrealized losses on these securities were $0.3 million at September 30, 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. 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 September 30, 2016. All securities were evaluated for OTTI at September 30, 2016 and December 31, 2015. The result of this evaluation showed no OTTI as of September 30, 2016 or December 31, 2015. The estimated weighted average duration of MBS was 4.3 years at September 30, 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 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 nine months ended September 30, 2016, net charge-offs totaled $5.9 million or 0.20% of average loans annualized, compared to $9.0 million, or 0.36% of average loans annualized, during the nine months ended September 30, 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 as follows: 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 23 quarters. During 2016, we increased the look-back period to 23 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 23 quarter look-back period. Qualitative adjustment factors consider various current internal and external conditions which are allocated among loan types and take into consideration: • Current underwriting policies, staff, and portfolio mix, • Internal trends of delinquency, nonaccrual and criticized loans by segment, • Risk rating accuracy, control and regulatory assessments/environment, • General economic conditions - locally and nationally, • Market trends impacting collateral values, • The competitive environment, as it could impact loan structure and underwriting, and • Valuation complexity by segment. 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 to or subtract from 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 approximately 8 quarters as of September 30, 2016. Our residential mortgage and consumer LEP remained at 4 quarters as of September 30, 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 in prior periods is the 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 qualitative estimates of valuation factors quarterly and management uses its judgement to make adjustments based on current trends. During the second quarter of 2016 as a result of continued improvement in the model and normal review of the factors, we removed the model estimation and complexity risk reserve from our calculation of the allowance of loan losses. 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 $14.2 million and $13.6 million for the periods ending September 30, 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 which remain in accrual status because they are considered well secured and are in the process of collection. The following tables show our nonaccrual and past due loans at the dates indicated: September 30, 2016 (In Thousands) 30–59 Days Past Due and Still Accruing 60–89 Days Past Due and Still Accruing Greater Than 90 Days Past Due and Still Accruing Total Past Due And Still Accruing Accruing Acquired Nonaccrual Total Loans Commercial $ 354 $ 1,297 $ — $ 1,651 $ 1,251,430 $ 9,691 $ 3,945 $ 1,266,717 Owner-occupied commercial 572 — — 572 1,043,890 10,673 2,510 1,057,645 Commercial mortgages 3,096 6,902 — 9,998 1,123,939 12,880 7,086 1,153,903 Construction — — — — 205,384 3,592 — 208,976 Residential 4,867 157 — 5,024 257,308 899 5,480 268,711 Consumer 788 135 271 1,194 432,445 368 4,151 438,158 Total (1) $ 9,677 $ 8,491 $ 271 $ 18,439 $ 4,314,396 $ 38,103 $ 23,172 $ 4,394,110 % of Total Loans 0.22 % 0.19 % 0.01 % 0.42 % 98.18 % 0.87 % 0.53 % 100 % (1) The balances above include $766.9 million of acquired nonimpaired loans.

Interest income of $0.5 million and $0.8 million was recognized on impaired loans during the three and nine months ended September 30, 2016, respectively. Interest income of $0.4 million and $1.3 million was recognized on impaired loans during the three and nine months ended September 30, 2015. As of September 30, 2016, there were 27 residential loans and 12 commercial loans in the process of foreclosure. The total outstanding balance on the loans was $4.9 million and $2.0 million, 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 $0.7 million, respectively. Reserves on Acquired Nonimpaired Loans In accordance with FASB ASC 310, loans acquired by the Bank through its merger with FNBW, Alliance and Penn Liberty 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. The following tables provide an analysis of loans by portfolio segment based on the credit quality indicators used to determine the Allowance for Loan Loss.

Troubled Debt Restructurings (TDR) TDRs are recorded in accordance with FASB ASC 310-40, Troubled Debt Restructuring by Creditors (ASC 310-40) During the nine months ended September 30, 2016, the terms of 20 loans were modified in TDRs. Twelve modifications were for consumer loans of which ten were HELOC conversions and two loans were discharged in bankruptcy. Six were residential mortgages; three received rate reduction and maturity date extension, two received forbearance agreements and one residential mortgage was discharged in bankruptcy. One commercial loan in bankruptcy was granted interest-only payments and one commercial loan was granted a maturity date extension. 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.

For the same period of 2015, the TDRs set forth in the table above increased our allowance for loan losses less than $0.1 million through the allocation of a related reserve and resulted in charge-offs of less than $0.1 million.

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 their 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 $23.1 million at September 30, 2016. The portfolio consists of 80 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 $42.1 million exceeds the outstanding book balance at September 30, 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 September 30, 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 September 30, 2016, the internal rate of return (IRR) of 19.49% 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 expected to be liquidated. As of September 30, 2016, the Company’s actuarially estimated cash payments to reverse mortgagors are as follows: (Dollars in thousands) Year Ending 2016 $ 266 2017 433 2018 341 2019 265 2020 204 Years 2021 - 2025 471 Years 2026 - 2030 95 Years 2031 - 2035 14 Thereafter 2 Total (1) $ 2,091 (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 $6.4 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 $0.7 million for the quarter ended September 30, 2016 with an IRR of 18.76%. If the future changes in collateral value were assumed to be reduced by 1%, income would decrease by $0.3 million with an IRR of 19.16%. 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 $1.2 million. If the IRR decreased by 1%, the net present value would decrease by $1.2 million.

Income Taxes	10. 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 September 30, 2016. We record interest and penalties on potential income tax deficiencies as income tax expense. Our federal and state tax returns for the 2013 through 2015 tax years are subject to examination as of September 30, 2016. Pennsylvania is currently auditing our 2012 and 2013 state tax returns. 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 nine months ended September 30, 2016 were $1.2 million, $1.2 million and $0.3 million, respectively. The carrying value of the investment in affordable housing credits is $10.8 million at September 30, 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 September 30, 2016 and December 31, 2015 by level in the valuation hierarchy (as described above): (Dollars in thousands) September 30, 2016 Quoted Significant Significant Total Fair Assets measured at fair value on a recurring basis Available-for-sale securities: CMO $ — $ 264,741 $ — $ 264,741 FNMA MBS — 380,291 — 380,291 FHLMC MBS — 68,172 — 68,172 GNMA MBS — 28,868 — 28,868 GSE — 35,136 — 35,136 Other investments 627 — — 627 Total assets measured at fair value on a recurring basis $ 627 $ 777,208 $ — $ 777,835 Assets measured at fair value on a nonrecurring basis Other real estate owned $ — $ — $ 3,232 $ 3,232 Loans held-for-sale — 61,198 — 61,198 Impaired loans, net — — 40,458 40,458 Total assets measured at fair value on a nonrecurring basis $ — $ 61,198 $ 43,690 $ 104,888 (Dollars in thousands) December 31, 2015 Quoted Significant Significant Total Fair 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 September 30, 2016 and no material liabilities measured at fair value as of September 30, 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 September 30, 2016, securities classified as available-for-sale are reported at fair value using Level 2 inputs, except for one mutual fund asset related to the Penn Liberty acquisition, which is categorized as Level 1. Included in the Level 2 total are approximately $35.1 million in U.S. Treasury Notes and Federal Agency debentures, and $742.1 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 $44.1 million and $37.7 million at September 30, 2016 and December 31, 2015, respectively. The valuation allowance on impaired loans was $3.6 million as of September 30, 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 in “Fair Value of Financial Assets and Liabilities” section above). Loans Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type: commercial, commercial mortgages, owner-occupied commercial construction, residential mortgages and consumer. For loans that reprice frequently, the book value approximates fair value. The fair values of other types of loans 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. Stock in the Federal Home Loan Bank (FHLB) of Pittsburgh The fair value of FHLB stock is assumed to be equal to its cost basis, since the stock is non-marketable but redeemable at its par value. Other assets Other assets includes, among others, 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 and 2016 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 September 30, 2016, and the evaluation showed no OTTI as of September 30, 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 $13.3 million as of September 30, 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: (Dollars in thousands) Fair Value September 30, 2016 December 31, 2015 Measurement Book Value Fair Value Book Value Fair Value Financial assets: Cash and cash equivalents Level 1 $ 813,405 813,405 $ 561,179 $ 561,179 Investment securities available-for-sale Level 2 777,835 777,835 721,029 721,029 Investment securities held-to-maturity Level 2 164,880 169,562 165,862 167,743 Loans, held-for-sale Level 2 61,198 61,198 41,807 41,807 Loans, net (1) Level 2 4,306,569 4,283,862 3,693,964 3,637,714 Impaired loans, net Level 3 40,458 40,458 35,086 35,086 Reverse mortgage loans Level 3 23,120 23,120 24,284 24,284 Stock in FHLB of Pittsburgh Level 2 36,710 36,710 30,519 30,519 Accrued interest receivable Level 2 15,257 15,257 14,040 14,040 Other assets Level 3 7,277 16,625 8,669 18,416 Financial liabilities: Deposits Level 2 4,733,639 4,528,014 4,016,566 3,791,606 Borrowed funds Level 2 1,144,707 1,143,498 932,886 933,905 Standby letters of credit Level 3 284 284 195 195 Accrued interest payable Level 2 3,658 3,658 801 801 (1) Excludes impaired loans, net.

Indemnifications and Guarantees	13. INDEMNIFICATIONS AND GUARANTEES Secondary Market Loan Sales Given the current interest rate environment, coupled with our desire not to hold newly originated residential mortgage loans in our portfolio, we generally sell these assets 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 results in monthly service fee income. The mortgage servicing rights 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 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 nine months ended September 30, 2016. Swap Guarantees We entered into agreements with three 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 that the customer defaults on the swap agreement and the agreement is in a paying position to the third-party financial institution. This is a customary arrangement that allows 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 September 30, 2016 there were 130 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 aggregate amount was approximately $498.6 million at September 30, 2016 compared to $481.6 million at December 31, 2015. At September 30, 2016 maturities ranged from one month to over 19 years. The aggregate market value of these swaps to the customers was a liability of $27.2 million at September 30, 2016 and $18.1 million at December 31, 2015. There were no reserves for the swap guarantees as of September 30, 2016.

Legal and Other Proceedings	15. LEGAL AND OTHER PROCEEDINGS As we disclosed in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2016, a tentative settlement was reached in the litigation 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 (Bkcy. E. D. PA). The settlement has since been approved by the court, and the case has been dismissed. 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.

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.
Acquisitions	Acquisitions On August 12, 2016 we completed the acquisition of Penn Liberty Financial Corp. (Penn Liberty), a community bank headquartered in Wayne, Pennsylvania. We expect this acquisition to build our market share, deepen our presence in the southeastern Pennsylvania market, and enhance our customer base. The results of Penn Liberty’s operations are included in our Consolidated Financial Statements since the date of the acquisition. See Note 2 – Business Combinations for further information. Also during the third quarter, we acquired the assets of Powdermill Financial Solutions LLC (Powdermill), a multi-family office serving an affluent clientele in the local community and throughout the United States. This acquisition aligns with our strategic plan to expand our wealth management offerings and to diversify our fee-income generating businesses.
Derivatives and Hedging	Derivatives and Hedging During the third quarter of 2016, we implemented a hedging program to manage our interest rate risk. This program did not have a material effect on our statements of condition or results of operations.
