Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Organization Univest Corporation of Pennsylvania (the Corporation) through its wholly owned subsidiary, Univest Bank and Trust Co. (the Bank), is engaged in domestic commercial and consumer banking services and provides a full range of banking and trust services to its customers. The Bank wholly owns Univest Capital, Inc., which provides lease financing, and Delview, Inc., who through its subsidiaries, Univest Investments, Inc., Univest Insurance, Inc. and Girard Partners provides financial planning, investment management, investment advisory, insurance products and brokerage services. Univest Investments, Inc., Univest Insurance, Inc. and Univest Capital, Inc. were formed to enhance the traditional banking and trust services provided by the Bank, along with the acquisition of Girard Partners. At December 31, 2016 , the Corporation has three reportable business segments: Banking, Wealth Management and Insurance. The Corporation determines its segments based primarily upon product and service offerings, through the types of income generated and the regulatory environment. This is strategically how the Corporation operates and has positioned itself in the marketplace. Accordingly, significant operating decisions are based upon analysis of each of these segments. For more detailed discussion and financial information on the business segments, see Note 23 “Segment Reporting.” The Bank serves Montgomery, Bucks, Chester, Philadelphia, Lancaster and Lehigh Counties of Pennsylvania and Cape May County in New Jersey through thirty-seven banking offices and provides banking and trust services to the residents and employees of fourteen retirement communities. Principles of Consolidation The consolidated financial statements include the accounts of the Corporation and its wholly owned subsidiaries; the Corporation’s primary subsidiary is the Bank. All significant intercompany balances and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current-year presentation. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include fair value measurement of investment securities available-for-sale and assessment for impairment of certain investment securities, reserve for loan and lease losses, valuation of goodwill and other intangible assets, mortgage servicing rights, deferred tax assets and liabilities, benefit plans and stock-based compensation expense. Interest-earning Deposits with Other Banks Interest-earning deposits with other banks consist of deposit accounts with other financial institutions generally having maturities of three months or less. At times, such balances exceed the FDIC limits for insurance coverage. Investment Securities Securities are classified as investment securities held-to-maturity and carried at amortized cost if management has the positive intent and ability to hold the securities to maturity. Securities purchased with the intention of recognizing short-term profits are placed in the trading account and are carried at fair value. The Corporation did not have any trading account securities at December 31, 2016 or 2015 . Securities not classified as held-to-maturity or trading are designated securities available-for-sale and carried at fair value with unrealized gains and losses, net of estimated income taxes, reflected in accumulated other comprehensive income, a separate component of shareholders' equity. Securities classified as available-for-sale are those securities that the Corporation intends to hold for an indefinite period of time but not necessarily to maturity. Any decision to sell a security classified as available-for-sale would be based on various factors, including interest rates, changes in the maturity or mix of the Corporation's assets and liabilities, liquidity needs, regulatory capital considerations and other factors. Management determines the appropriate classification of debt securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Purchase premiums and discounts are recognized in interest income using the interest method over the expected life of the securities. Due to volatility in the financial markets, there is the risk that any future fair value could vary from that disclosed in the accompanying financial statements. Realized gains and losses on the sale of investment securities are recorded on the trade date, determined using the specific identification method and are included in the consolidated statements of income. Management evaluates debt securities, which are comprised of U.S. government, government sponsored agencies, municipalities, corporate bonds and other issuers, for other-than-temporary impairment by considering the current economic conditions, the length of time and the extent to which the fair value has been less than cost, market interest rates and the credit rating of each security. Unrealized losses on the Corporation’s investments in debt securities that are deemed in debt securities are temporary in nature are recognized in other comprehensive income, net of tax. Should it be determined that a security is impacted by deteriorating credit, the credit portion of the loss is recognized in earnings. The Corporation does not have the intent to sell the debt securities and believes it is more likely than not, that it will not have to sell the securities before recovery of their cost basis. The Corporation evaluates its equity securities for other-than-temporary impairment. Other-than-temporary impairment charges are recorded when the Corporation determines the fair value of certain equity securities will not recover the cost basis of the individual security within a reasonable period of time due to a decline in the financial stability of the underlying companies. Management evaluates the near-term prospects of the issuers in relation to the severity and duration of the impairment. The Corporation has the intent and ability to hold these securities until recovery of the Corporation’s cost basis occurs. Federal Home Loan Bank Stock, Federal Reserve Bank Stock and Certain Other Investments without Readily Determinable Fair Values At December 31, 2016 and 2015 , the Bank held $14.6 million and $6.6 million , respectively, in Federal Reserve Bank stock as required by the Federal Reserve Bank. The Bank is a member of the FHLB, and as such, is required to hold FHLB stock as a condition of membership as determined by the FHLB. The Bank is required to hold additional stock in the FHLB in relation to the level of outstanding borrowings. The Bank held FHLB stock of $10.1 million and $2.2 million at December 31, 2016 and 2015 , respectively. Additionally, the FHLB might require its members to increase their capital stock investments. Changes in the credit ratings of the U.S. government and federal agencies, including the FHLB, could increase the borrowing costs of the FHLB and possibly have a negative impact on its operations and long-term performance. It is possible this could have an adverse effect on the value of the Corporation’s investment in FHLB stock. Because ownership is restricted, the fair values of these investments are not readily determinable. As such, these investments are recorded at cost and evaluated for other-than-temporary impairment. The Corporation determined there was no other-than-temporary impairment of its investments in these stocks at December 31, 2016 or 2015 . Loans Held for Sale The Corporation originates mortgage loans for investment and for sale. At origination, a mortgage loan is identified as either for sale or for investment. Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value. Net unrealized losses are recognized by charges to non-interest income. Cash payments and cash receipts resulting from acquisitions and sales of loans are classified as operating cash flows if those loans are acquired specifically for resale. Cash receipts resulting from sales of loans that were not specifically acquired for resale are classified as investing cash inflows regardless of a change in the purpose for holding those loans. Loans and Leases Loans and leases are stated at the principal amount less net deferred fees and unearned discount. Interest income on commercial loans, real estate loans excluding residential real estate loans, and consumer loans is recorded on the outstanding balance method, using actual interest rates applied to daily principal balances. Interest on residential real estate loans is recorded based on the outstanding balance using the actual interest rate based upon a monthly interest calculation. Loan commitments are made to accommodate the financial needs of the customers. These commitments represent off-balance sheet items that are unfunded. The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet financial instruments. Accrual of interest income on loans and leases ceases when collectability of interest and/or principal is questionable. If it is determined that the collection of interest previously accrued is uncertain, such accrual is reversed and charged to current earnings. Loans and leases are considered past due based upon failure to comply with contractual terms. A loan or lease is typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest, even though the loan or lease is currently performing. When a loan or lease, including a loan or lease that is impaired, is classified as nonaccrual, the accrual of interest on such a loan or lease is discontinued. A loan or lease may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan or lease is placed on nonaccrual status, unpaid interest credited to income is reversed and the amortization of the net deferred fees is suspended. Interest payments received on nonaccrual loans and leases are either applied against principal or reported as interest income, according to management’s judgment as to the ultimate collectability of principal. Loans and leases are usually restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. A loan or lease is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the loan agreement or when a loan or lease is classified as a troubled debt restructuring. Interest on impaired loans and leases, which are not classified as nonaccrual, is recognized on the accrual basis. Acquired Loans Acquired loan portfolios are initially recorded at the acquisition date fair value. The fair value is based on guidance which defines fair value as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Level 3 inputs are utilized to value the portfolio and include the use of present value techniques employing cash flow estimates and incorporate assumptions that marketplace participants would use in estimating fair values. In instances where reliable market information is not available, the Corporation uses assumptions in an effort to determine reasonable fair value. Specifically, management utilizes three separate fair value analyses which a market participant would employ in estimating the total fair value adjustment. The three separate fair valuation methodologies used are: 1) interest rate loan fair value analysis; 2) general credit fair value analysis; and 3) specific credit fair value analysis. There is no carryover related allowance for loan losses. For loans acquired without evidence of credit quality deterioration, the fair value adjustments to reflect the fair value of the loans and the fair value adjustments to reflect the general credit risk of the loan portfolio are substantially recognized as interest income on a level yield amortization method based upon the expected life of the loan. Subsequent to the acquisition, the Corporation records a provision for loan loss for the acquired non-impaired loans only when additional deterioration of the portfolio is identified over the projections utilized in the initial fair value analysis. For loans acquired with evidence of credit quality deterioration , the Corporation prepares a specific credit fair value adjustment. Management reviews the acquired loan portfolio for loans meeting the definition of an impaired loan with deteriorated credit quality. Loans meeting this definition are reviewed by comparing the contractual cash flows to expected collectible cash flows. The aggregate expected cash flows less the acquisition date fair value results in an accretable yield amount. The accretable discount amount is recognized over the life of the loans on a level yield basis as an adjustment to yield. Any disposals of loans, including sales of loans, payments in full or foreclosures result in the derecognition of the loan at its carrying value with differences in actual results reflected in interest income. After the acquisition measurement period, the present value of any decreases in expected cash flows of purchased impaired loans will generally result in an impairment charge recorded as a provision for loan loss, resulting in an increase to the allowance. Loan and Lease Fees Fees collected upon loan or lease origination and certain direct costs of originating loans and leases are deferred and recognized over the contractual lives of the related loans and leases as yield adjustments using the interest method. Upon prepayment or other disposition of the underlying loans and leases before their contractual maturities, any associated unearned fees or unamortized costs are recognized. Reserve for Loan and Lease Losses The reserve for loan and lease losses is maintained at a level representing management's best estimate of known risks and inherent losses in the portfolio, based upon management's evaluation of the portfolio's collectability. Management evaluates the need to establish reserves against losses on loans on a quarterly basis. When changes in the reserve are necessary, an adjustment is made. The reserve for loan and lease losses is adjusted through provisions for loan and lease losses charged against or credited to income. Loans deemed to be uncollectible are charged against the reserve for loan and lease losses, and any subsequent recoveries are credited to the reserve. Reserve Required for Impaired Loans and Leases A loan or lease is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect future payments of principal or interest as contractually due. The Bank applies its normal loan review procedures in determining if a loan is impaired, which includes reviewing the collectability of delinquent and internally classified loans on a regular basis and at least quarterly. In determining the likelihood of collecting principal and interest, the Bank considers all available and relevant information, including the borrower's actual and projected cash flows, balance sheet strength, liquidity and overall financial position. Additionally, all loans classified as a troubled debt restructurings are considered impaired. When a loan is classified as impaired, an impairment analysis is performed within the quarter in which a loan is identified as impaired to determine if a valuation allowance is needed. The Bank re-examines each impaired loan on a quarterly basis to determine if any adjustment to the net carrying amount of a loan is required. The Bank recognizes charge-offs associated with impaired loans when all or a portion of a loan is considered to be uncollectible. In measuring impairment, the Bank determines whether or not the loan is collateral dependent. A loan is collateral dependent if repayment is expected to be provided solely by the underlying collateral, which includes repayment from the proceeds from the sale of the collateral, cash flows from the continued operation of the collateral, or both, and there are no other available and reliable repayment sources. To determine the initial amount of impairment for a collateral dependent loan, the Bank utilizes a recent appraisal, an agreement of sale or a letter of intent. If the fair value of the underlying collateral, less costs to sell, is less than the loan's carrying amount, the Bank establishes a provision to the reserve for loan and lease losses in the amount of the difference between fair value, less costs to sell, and the loan or lease's carrying amount. In subsequent periods, the Bank takes into consideration current facts and circumstances in analyzing whether the fair value of the collateral has increased or decreased significantly such that a change to the corresponding valuation allowance is required. If current facts and circumstances are insufficient to determine fair value, the Bank obtains a new appraisal. For loans that are not collateral dependent, the Bank establishes a specific reserve on impaired loans based on management's estimate of the discounted cash flows the Bank expects to receive from the borrower. Factors considered in evaluating such cash flows include: (1) the strength of the customer's personal or business cash flows and personal guarantees; (2) the borrower's effort to cure the delinquency; (3) the availability of other sources of repayment; (4) the type and value of collateral, if applicable; and (5) the strength of our collateral position, if applicable. General Reserve on the Remainder of the Portfolio The Bank establishes a general reserve for loans and leases that are not considered impaired to recognize the inherent losses associated with lending activities. This general reserve is determined by segmenting the loan portfolio and assigning reserve factors to each category. The reserve factors are calculated using the Bank's historical losses and loss emergence periods, and are adjusted for significant factors that, in management's judgment, affect the collectability of the portfolio as of the evaluation date. These significant factors include: • Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off and recovery practices not considered elsewhere in estimating credit losses; • Changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments; • Changes in the nature and volume of the portfolio and in the terms of loans; • Changes in the experience, ability, and depth of lending management and other relevant staff; • Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans; • Changes in the quality of the institution’s loan review system; • Changes in the value of underlying collateral for collateral-dependent loans; • The existence and effect of any concentrations of credit, and changes in the level of such concentrations; and • The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the institution’s existing portfolio. The Corporation maintains a reserve in other liabilities for off-balance sheet credit exposures that currently are unfunded in categories with historical loss experience. In addition, the Bank's primary examiner, as a regular part of their examination process, may require the Bank to increase the level of reserves. Premises and Equipment Land is stated at cost, and premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method and charged to operating expenses over the estimated useful lives of the assets or, for leasehold improvements, over the life of the related lease if less than the estimated useful life of the asset. The estimated useful life for new buildings constructed on land owned is forty years , and for new buildings constructed on leased land, is the lesser of forty years or the lease term including anticipated renewable terms. The useful life of purchased existing buildings is the estimated remaining useful life at the time of the purchase. Land improvements are considered to have estimated useful lives of fifteen years or the lease term including anticipated renewable terms. Furniture, fixtures and equipment have estimated useful lives ranging from three to ten years. When assets are retired, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts. Goodwill and Other Intangible Assets The Corporation accounts for its acquisitions using the purchase accounting method. Purchase accounting requires the total purchase price to be allocated to the estimated fair values of assets acquired and liabilities assumed, including certain intangible assets that must be recognized. Typically, this allocation results in the purchase price exceeding the fair value of net assets acquired, which is recorded as goodwill. Core deposit intangibles are a measure of the value of checking, money market and savings deposits acquired in business combinations accounted for under the purchase method. Core deposit intangibles are amortized using the sum of the year’s digits over their estimated useful lives of up to fifteen years . Customer related intangibles are amortized over their estimated useful lives of five to twelve years. Covenants not to compete are amortized over their three to five -year contractual lives on a straight-line basis. The Corporation completes a goodwill analysis at least on an annual basis or more often if events and circumstances indicate that there may be impairment. The Corporation also completes an impairment test for other intangible assets on an annual basis or more often if events and circumstances indicate a possible impairment. There can be no assurance that future impairment analyses will not result in a charge to earnings. Mortgage servicing rights are recognized as separate assets when mortgage loans are sold and the servicing rights are retained. Capitalized mortgage servicing rights are reported in other intangible assets on the consolidated balance sheets and are amortized into noninterest income in proportion to, and over the period of, estimated net servicing income on a basis similar to the interest method and an accelerated amortization method for loan payoffs. Mortgage servicing rights are evaluated for impairment, on a quarterly basis, based upon the fair value of the servicing rights as compared to amortized cost. The Corporation estimates the fair value of mortgage servicing rights using discounted cash flow models that calculate the present value of estimated future net servicing income. The model uses readily available prepayment speed assumptions for the current interest rates of the portfolios serviced. Mortgage servicing rights are carried at the lower of amortized cost or estimated fair value. Impairment is recognized through a valuation allowance, to the extent that fair value is less than the unamortized capitalized amount. Bank Owned Life Insurance The Corporation has invested in bank-owned life insurance (BOLI). BOLI involves the purchasing of life insurance by the Corporation for certain employees. The Corporation is the owner and beneficiary of the policies, however certain policies include split-dollar endorsements. Under these endorsements, beneficiaries of the insured individuals are entitled to a portion of the proceeds from the policy upon death of the insured. The life insurance investment is carried at the net cash surrender value of the underlying policies. Changes in the net cash surrender value of these policies are reflected in noninterest income. Proceeds from and purchases of bank owned life insurance are reflected in the consolidated statements of cash flows under investing activities. The Corporation recognizes a liability for the future death benefit for certain endorsement split-dollar life insurance arrangements that provide an employee with a death benefit in a postretirement/termination period. Other Real Estate Owned Other real estate owned (OREO) represents properties acquired through customers’ loan defaults and is included in other assets. The real estate is originally stated at an amount equal to the fair value of the property, less estimated costs to sell. The fair value less cost to sell becomes the "original cost" of the OREO asset. The amount, if any, by which the carrying amount of the loan plus recorded accrued interest (the recorded loan amount) exceeds the fair value less cost to sell of the OREO, the loss is charged against the reserve for loan and lease losses at the time of foreclosure or repossession. If the fair value less cost to sell of the OREO asset when taken into possession is greater than the recorded loan amount, the excess is first applied as a recovery against any prior charge-offs of the loan and any remaining gain is recorded as other noninterest income. Subsequently, OREO will be reported at the lower of the original cost and the current the fair value less cost to sell. Subsequent write-downs and any gain or loss upon the sale of OREO is recorded in other noninterest income. Capital improvement expenses associated with the construction or repair of the property are capitalized as part of the cost of the OREO asset; however, the capitalized expenses may not increase the OREO asset's recorded value to an amount greater than the asset's fair value after improvements and less cost to sell. Overages and subsequent carrying costs are expensed as incurred. Derivative Financial Instruments The Corporation recognizes all derivative financial instruments on its balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through income. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative are either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings, or recognized in other comprehensive income until the underlying forecasted transaction is recognized in earnings. The ineffective portion of a derivative's change in fair value is recognized in earnings immediately. To determine fair value, the Corporation uses third party pricing models that incorporate assumptions about market conditions and risks that are current at the reporting date. The Corporation may use interest-rate swap agreements to modify interest rate characteristics from variable to fixed or fixed to variable in order to reduce the impact of interest rate changes on future net interest income. The Corporation accounts for its interest-rate swap contracts in cash flow hedging relationships by establishing and documenting the effectiveness of the instrument in offsetting the change in cash flows of assets or liabilities that are being hedged. To determine effectiveness, the Corporation performs an analysis to identify if changes in fair value of the derivative correlate to the equivalent changes in the forecasted interest receipts related to a specified hedged item. Recorded amounts related to interest-rate swaps are included in other assets or liabilities. Changes in the fair value of derivative instruments designated as hedges of future cash flows are recognized in accumulated other comprehensive income until the underlying forecasted transactions occur, at which time the deferred gains and losses are recognized in earnings. The change in fair value of the ineffective part of the instrument would be charged to earnings, potentially causing material fluctuations in reported earnings in the period of the change relative to comparable periods. In a fair value hedge, the fair values of the interest rate swap agreements and changes in the fair values of the hedged items are recorded in the Corporation’s consolidated balance sheet with the corresponding gain or loss being recognized in the consolidated statement of income. The difference between changes in the fair values of interest rate swap agreements and the hedged items represents hedge ineffectiveness and is recorded in net interest income in the consolidated statement of income. The Corporation performs an assessment, both at the inception of the hedge and quarterly thereafter, to determine whether these derivatives are highly effective in offsetting changes in the value of the hedged items. The Corporation has agreements with third-party financial institutions whereby the third-party financial institution enters into interest rate derivative contracts and foreign currency swap contracts with loan customers referred to them by the Corporation. The Corporation records the fair value of credit derivatives in other liabilities on the consolidated balance sheets. The Corporation recognizes changes in the fair value of credit derivatives, net of any fees received, in other noninterest income in the consolidated statements of income. In connection with its mortgage banking activities, the Corporation enters into commitments to originate certain fixed-rate residential mortgage loans for customers, also referred to as interest rate locks. In addition, the Corporation enters into forward commitments for the future sale of mortgage loans to third-party investors to hedge the effect of changes in interest rates on the value of the interest rate locks. Forward loan sale commitments may also be in the form of commitments to sell individual mortgage loans at a fixed price at a future date. Both the interest rate locks and the forward loan sale commitments are accounted for as derivatives and carried at fair value, determined as the amount that would be necessary to settle each derivative financial instrument at the balance sheet date. Gross derivative assets and liabilities are recorded within other assets and other liabilities on the consolidated balance sheets, with changes in fair value during the period recorded within the net gain on mortgage banking activities on the consolidated statements of income. Income Taxes There are two components of income tax expense: current and deferred. Current income tax expense approximates cash to be paid or refunded for taxes for the applicable period. Deferred income taxes are provided for temporary differences between amounts reported for financial statement and tax purposes. Deferred income taxes are computed using the asset and liability method, such that deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between financial reporting amounts and the tax basis of existing assets and liabilities based on currently enacted tax laws and tax rates in effect for the periods in which the differences are expected to reverse. Deferred tax assets are subject to management’s judgment based upon available evidence that future realizations are “more likely than not.” If management determines that the Corporation is not more likely than not, to realize some or all of the net deferred tax asset in the future, a charge to income tax expense may be required to reduce the value of the net deferred tax asset to the expected realizable value. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Penalties are recorded in noninterest expense in the year they are assessed and paid and are treated as a non-deductible expense for tax purposes. Interest is recorded in noninterest expense in the year it is assessed and paid and is treated as a deductible expense for tax purposes. Retireme

Business Combinations [Abstract]
Acquisition	Acquisition Fox Chase Bancorp On July 1, 2016, the Corporation completed the merger of Fox Chase Bancorp into the Corporation and Fox Chase Bank into Univest Bank and Trust Co. Fox Chase Bank was a locally-managed institution with locations in Pennsylvania and New Jersey and headquartered in Hatboro, Pennsylvania. The Corporation's presence expanded in Bucks, Chester, Philadelphia and Montgomery counties in Pennsylvania and into Cape May county in New Jersey, complementing and expanding the Corporation's existing network of financial centers. The fair value of total assets acquired as a result of the merger totaled $1.1 billion , loans totaled $776.2 million and deposits totaled $738.3 million . In accordance with the terms of the Agreement and Plan of Merger, dated December 8, 2015, holders of shares of Fox Chase common stock received, in aggregate, $98.9 million in cash and 6,857,529 shares or approximately 26% of the post transaction outstanding shares of the Corporation's common stock. The transaction was valued at $242.2 million based on Corporation’s June 30, 2016 closing share price of $21.02 as quoted on NASDAQ. The results of the combined entity’s operations are included in the Corporation's Consolidated Financial Statements from the date of acquisition. Goodwill of $59.9 million , which is the excess of the merger consideration over the estimated fair value of net assets acquired, was recorded in the Fox Chase acquisition and represents the anticipated revenue growth and reduced expenses as a result of the acquisition. The acquisition of Fox Chase is being accounted for as a business combination using the acquisition method of accounting, which includes estimating the fair value of assets acquired, liabilities assumed and consideration paid as of the acquisition date. The following table summarized the consideration paid for Fox Chase and the fair value of assets acquired and liabilities assumed at the acquisition date: (Dollars in thousands, except share data) Purchase price consideration in common stock: Fox Chase common shares outstanding 11,754,852 Fox Chase common shares settled for stock 7,047,096 Exchange ratio 0.9731 Univest shares issued 6,857,529 Univest closing stock price at June 30, 2016 $ 21.02 Purchase price assigned to Fox Chase common shares exchanged for Univest stock $ 144,146 Fox Chase common shares settled for cash 4,707,756 Purchase price for shares exchanged for cash $ 21.00 Purchase price assigned to Fox Chase common shares exchanged for cash 98,863 Purchase price assigned to cash in lieu of fractional shares 11 Purchase price assigned to Fox Chase options settled for cash 4,255 Purchase price consideration - ESOP and Equity Incentive Plan (5,041 ) Total purchase price $ 242,234 Fair value of assets acquired: Cash and due from banks $ 3,253 Interest-earning deposits with other banks 15,629 Investment securities available-for-sale 230,682 Loans held for investment 776,214 Premises and equipment, net 13,146 Other real estate owned 2,510 Core deposit intangible * 5,268 Bank owned life insurance 26,119 Accrued interest receivable and other assets 20,827 Total identifiable assets $ 1,093,648 Fair value of liabilities assumed: Deposits - noninterest bearing $ 35,285 Deposits - interest bearing 702,978 Short-term borrowings 48,500 Long-term debt 123,448 Accrued interest payable and other liabilities 1,105 Total liabilities $ 911,316 Identifiable net assets 182,332 Goodwill resulting from merger * $ 59,902 * Goodwill is not deductible for federal income tax purposes. The goodwill and core deposit intangible are allocated to the Banking business segment. The following is a description of the valuation methodologies used to estimate the fair values of major categories of assets acquired and liabilities assumed. In many cases, determining the fair value of the acquired assets and assumed liabilities required the Corporation to estimate cash flows expected to result from those assets and liabilities and to discount those cash flows at appropriate rates of interest, which required the utilization of significant estimates and judgment in accounting for the acquisition. Cash and due from banks: The fair value of cash and due from banks is their stated value. Investment securities available-for-sale: The estimated fair values of the investment securities available for sale, primarily comprised of U.S. government agency mortgage-backed securities and corporate bonds, were determined using Level 2 inputs in the fair value hierarchy. The fair values were determined using independent pricing services and market-participating brokers. The Corporation’s independent pricing service utilized evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information for structured securities, cash flow and, when available, loan performance data. Because many fixed income securities do not trade on a daily basis, the pricing service’s evaluated pricing applications apply information as applicable through processes, such as benchmarking of like securities, sector groupings, and matrix pricing, to prepare evaluations. Management reviewed the data and assumptions used in pricing the securities. A fair value premium of $3.4 million was recorded and is being amortized over the estimated useful life of the investments (estimated average remaining life of 3.7 years ) using the interest rate method. Loans held for investment: The most significant fair value determination related to the valuation of acquired loans. The acquisition resulted in loans acquired with and without evidence of credit quality deterioration. There was no carryover related allowance for loan and lease losses. The acquired loan portfolio was valued based on current guidance which defines fair value as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Level 3 inputs were utilized to value the portfolio and included the use of present value techniques employing cash flow estimates and incorporated assumptions that marketplace participants would use in estimating fair values. In instances where reliable market information was not available, the Corporation used assumptions in an effort to determine reasonable fair value. Specifically, management utilized three separate fair value analyses which a market participant would employ in estimating the total fair value adjustment. The three separate fair valuation methodologies used were: 1) interest rate fair value analysis; 2) general credit fair value analysis; and 3) specific credit fair value analysis. For loans acquired without evidence of credit quality deterioration, the Corporation prepared the interest rate fair value analysis. Loans were grouped by characteristics such as loan type, term, collateral and rate. Market rates for similar loans were obtained from various external data sources and reviewed by management for reasonableness. The average of these rates was used as the fair value interest rate a market participant would utilize. A present value approach was utilized to calculate the interest rate fair value adjustment. Additionally a general credit fair value adjustment was calculated using a two part general credit fair value analysis: 1) expected lifetime credit migration losses; and 2) estimated fair value adjustment for qualitative factors, liquidity and an additional discount for loans considered to have heightened risk but not considered impaired. The expected lifetime losses were calculated using an average of historical losses of the Bank, Fox Chase Bank and peer banks. The Corporation also estimated an environmental factor to apply to each loan type. The environment factor represents potential discount which may arise due to general economic conditions. Fox Chase's loan portfolio without evidence of credit quality deterioration was recorded at a current fair value of $762.5 million . A fair value premium of $4.7 million was recognized to reflect the fair values of loans. A fair value discount of $8.5 million was recognized to reflect the general credit risk of the loan portfolio. The adjustment is being substantially recognized as interest income over approximately 10 years on a level yield amortization method based upon the expected life of the loans. For loans acquired with evidence of credit quality deterioration the Corporation prepared a specific credit fair value adjustment. Management reviewed the acquired loan portfolio for loans meeting the definition of an impaired loan with deteriorated credit quality. Loans meeting this definition were reviewed by comparing the contractual cash flows to expected collectible cash flows. The aggregate expected cash flows less the acquisition date fair value results in an accretable yield amount. The accretable discount amount is being recognized over the life of the loans on a level yield basis as an adjustment to yield. Any disposals of loans, including sales of loans, payments in full or foreclosures result in the derecognition of the loan at its carrying value with differences in actual results reflected in interest income. At the acquisition date, the Corporation recorded $13.7 million of acquired impaired loans. The aggregate expected cash flows less the acquisition date fair value results in an accretable discount amount of $283 thousand , which is being recognized over the life of the loans on a level yield basis as an adjustment to yield. Contractual cashflows not expected to be collected of $11.1 million resulted in an unaccretable fair value discount of $5.7 million . The following is a summary of the acquired impaired loans at July 1, 2016 resulting from the acquisition with Fox Chase: (Dollars in thousands) Contractually required principal and interest payments $ 25,141 Contractual cash flows not expected to be collected (nonaccretable difference) (11,120 ) Cash flows expected to be collected 14,021 Interest component of expected cash flows (accretable discount) (283 ) Fair value of loans acquired with a deterioration of credit quality $ 13,738 Bank premises: The Corporation assumed ten owned properties. The fair value was determined taking into consideration the highest and best use of the properties from a market participant perspective. For those properties that the Corporation have held-for-sale, the fair value is reduced by the costs to sell. The fair value of bank premises were determined using Level 2 inputs in the fair value hierarchy. The fair value of the buildings of $4.4 million is being amortized over an estimated life of 30 years. Other real estate owned: The Corporation assumed five other real estate owned properties. The fair value was determined taking into consideration the highest and best use of the properties from a market participant perspective, including management assumptions when comparative data is not available, and is reduced by the costs to sell. The fair value of other real estate owned was determined using Level 3 inputs in the fair value hierarchy. Bank owned life insurance: The fair value was determined at the cash surrender value of the policies. Core deposit intangible: Core deposit intangible represents the value assigned to demand, interest checking, money market and savings accounts acquired as part of the acquisition. The core deposit intangible fair value represents the future economic benefit, including the present value of future tax benefits, of the potential cost savings from acquiring core deposits as part of an acquisition compared to the cost of alternative funding sources and was valued utilizing Level 3 inputs. The core deposit intangible of $5.3 million is being amortized using the sum of the years digits method over an estimated life of 10 years. Deposits: The fair values of demand and saving deposits, with no stated maturities, approximated the carrying value as these accounts are payable on demand. The fair values of time deposits with fixed maturities were estimated by discounting the final maturity using current market interest rate for similar instruments. A fair value premium of $831 thousand was recorded and is recognized as a reduction to interest expense using a level yield amortization method over the life of the time deposit. The fair value of time deposits were determined using Level 2 inputs in the fair value hierarchy. Federal funds: Federal funds are overnight funds. The fair value of federal funds was determined to be the carrying balance due to the using Level 2 inputs in the fair value hierarchy. Long-term debt: Fair values of long-term debt were estimated using discounted cash flow analysis based on rates currently available to the Bank for advances with similar terms and remaining maturities. The fair value of long-term borrowings was determined using Level 2 inputs in the fair value hierarchy. A fair value premium of $3.4 million was recognized and is recognized as a reduction to interest expense using a level yield amortization method over the life of the debt. Deferred tax assets and liabilities: Deferred tax assets and liabilities were established for purchase accounting fair value adjustments as the future amortization/accretion of these adjustments represent temporary differences between book income and taxable income. Direct costs related to the acquisition were expensed as incurred. For the year ended December 31, 2016 , the Corporation incurred $15.9 million of Fox Chase integration and acquisition-related costs, which have been separately stated in the Corporation's consolidated statements of income.

Unrealized losses in investment securities at December 31, 2016 and 2015 do not represent other-than-temporary impairments. Securities with a carrying value of $356.7 million and $210.1 million at December 31, 2016 and 2015 , respectively, were pledged to secure public deposits and for other purposes as required by law. In addition, securities of $1.4 million were pledged to secure credit derivatives and interest rate swaps at December 31, 2016 . See Note 17, "Derivative Instruments and Hedging Activities" for additional information. The following table presents information related to sales of securities available-for-sale during the years ended December 31, 2016 , 2015 and 2014 : For the Years Ended December 31, (Dollars in thousands) 2016 2015 2014 Securities available-for-sale: Proceeds from sales $ 77,290 $ 77,308 $ 32,967 Gross realized gains on sales 600 1,295 635 Gross realized losses on sales 82 30 — Tax expense related to net realized gains on sales 181 443 222 The Corporation did not recognize any other-than-temporary impairment charges on debt securities for the years ended December 31, 2016 , 2015 and 2014 . The Corporation realized other-than-temporary impairment charges to noninterest income of $0 thousand , $5 thousand , and $0 thousand on its equity portfolio during the years ended December 31, 2016 , 2015 and 2014 , respectively. At December 31, 2016 and 2015 , there were no investments in any single non-federal issuer representing more than 10% of shareholders’ equity. The following table shows the fair value of securities that were in an unrealized loss position at December 31, 2016 and 2015 by the length of time those securities were in a continuous loss position. For the investment securities in an unrealized loss position, the Corporation has concluded, based on its analysis, that the unrealized losses are primarily caused by the movement of interest rates and current market conditions. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the par value of the investment. It is more likely than not that the Corporation will not be required to sell the investments before a recovery of carrying value.

Credit Quality Indicators The following tables present by class, the recorded investment in loans and leases held for investment by credit quality indicator at December 31, 2016 and 2015 . The Corporation employs a ten (10) grade risk rating system related to the credit quality of commercial loans and residential real estate loans secured for a business purpose of which the first six categories are pass categories (credits not adversely rated). The following is a description of the internal risk ratings and the likelihood of loss related to each risk rating. Loans with risk ratings of one through five are reviewed based on the relationship dollar amount with the borrower: loans with a relationship total of $2.5 million or greater are reviewed quarterly; loans with a relationship balance of less than $2.5 million but greater than $500 thousand are reviewed annually based on the borrower’s fiscal year; loans with a relationship balance of less than $500 thousand are reviewed only if the loan becomes 60 days or more past due. Loans with a risk rating of six are also reviewed based on the relationship dollar amount with the borrower: loans with a relationship balance of $2.0 million or greater are reviewed quarterly; loans with a relationship balance of less than $2.0 million but greater than $500 thousand are reviewed annually; loans with a relationship balance of less than $500 thousand are reviewed only if the loan becomes 60 days or more past due. Loans with a risk rating of seven are reviewed at least quarterly, and as often as monthly, at management’s discretion. Loans with risk ratings of eight through ten are reviewed monthly. 1. Cash Secured—No credit risk 2. Fully Secured—Negligible credit risk 3. Strong—Minimal credit risk 4. Satisfactory—Nominal credit risk 5. Acceptable—Moderate credit risk 6. Pre-Watch—Marginal, but stable credit risk 7. Special Mention—Potential weakness 8. Substandard—Well-defined weakness 9. Doubtful—Collection in-full improbable 10.

Nonperforming loans and leases are loans past due 90 days or more, loans and leases on nonaccrual of interest and troubled debt restructured loans and lease modifications. Performing loans and leases are reviewed only if the loan becomes 60 days or more past due. Nonperforming loans and leases are reviewed monthly. Performing loans and leases have a nominal to moderate risk of loss.

Commercial, financial and agricultural loans, commercial real estate loans, construction loans and residential real estate loans with a business purpose are generally perceived as having more risk of default than residential real estate loans with a personal purpose and consumer loans. These types of loans involve larger loan balances to a single borrower or groups of related borrowers. Commercial real estate loans may be affected to a greater extent than residential loans by adverse conditions in real estate markets or the economy because commercial real estate borrowers’ ability to repay their loans depends on successful development of their properties and factors affecting residential real estate borrowers. Commercial, financial and agricultural business loans are typically based on the borrowers’ ability to repay the loans from the cash flow of their businesses. These loans may involve greater risk because the availability of funds to repay each loan depends substantially on the success of the business itself. In addition, the collateral securing the loans often depreciates over time, is difficult to appraise and liquidate and fluctuates in value based on the success of the business. Risk of loss on a construction loan depends largely upon whether our initial estimate of the property’s value at completion of construction equals or exceeds the cost of the property construction (including interest). During the construction phase, a number of factors can result in delays and cost overruns. If estimates of value are inaccurate or if actual construction costs exceed estimates, the value of the property securing the loan may be insufficient to ensure full repayment when completed through a permanent loan or by seizure of collateral. Included in real estate-construction is track development financing. Risk factors related to track development financing include the demand for residential housing and the real estate valuation market. When projects move slower than anticipated, the properties may have significantly lower values than when the original underwriting was completed, resulting in lower collateral values to support the loan. Extended time frames also cause the interest carrying cost for a project to be higher than the builder projected, negatively impacting the builder’s profit and cash flow and, therefore, their ability to make principal and interest payments. Commercial real estate loans and residential real estate loans with a business purpose secured by owner-occupied properties are dependent upon the successful operation of the borrower’s business. If the operating company suffers difficulties in terms of sales volume and/or profitability, the borrower’s ability to repay the loan may be impaired. Loans secured by properties where repayment is dependent upon payment of rent by third party tenants or the sale of the property may be impacted by loss of tenants, lower lease rates needed to attract new tenants or the inability to sell a completed project in a timely fashion and at a profit. Commercial, financial and agricultural loans, commercial real estate loans, construction loans and residential real estate loans secured for a business purpose are more susceptible to a risk of loss during a downturn in the business cycle. While the Corporation has strict underwriting, review, and monitoring procedures in place, these procedures cannot eliminate all of the risks related to these loans. The Corporation focuses on both assessing the borrower’s capacity and willingness to repay and on obtaining sufficient collateral. Commercial, financial and agricultural loans are generally secured by the borrower’s assets and by personal guarantees. Commercial real estate and residential real estate loans secured for a business purpose are originated primarily within the Southeastern Pennsylvania market area at conservative loan-to-value ratios and often with a guarantee of the borrowers. Management closely monitors the composition and quality of the total commercial loan portfolio to ensure that any credit concentrations by borrower or industry are closely monitored. The Corporation originates fixed-rate and adjustable-rate real estate-residential mortgage loans that are secured by the underlying 1-to-4 family residential properties for personal purposes. Credit risk exposure in this area of lending is minimized by the evaluation of the credit worthiness of the borrower, including debt-to-equity ratios, credit scores and adherence to underwriting policies that emphasize conservative loan-to-value ratios of generally no more than 80% . Residential mortgage loans granted in excess of the 80% loan-to-value ratio criterion are generally insured by private mortgage insurance. In the real estate-home equity loan portfolio secured for a personal purpose, credit exposure is minimized by the evaluation of the creditworthiness of the borrower, including debt-to-equity ratios, credit scores and adherence to the Corporation’s underwriting policies. Combined loan-to-value ratios are generally limited to 80% , but increased to 85% for the Corporation’s strongest profile borrower. Other credit considerations and compensating factors may support higher combined loan-to-value ratios. Credit risk for direct consumer loans is controlled by strict adherence to underwriting standards that consider debt-to-income levels and the creditworthiness of the borrower and, if secured, collateral values. These loans are included within the portfolio of loans to individuals. The primary risks that are involved with lease financing receivables are credit underwriting and borrower industry concentrations. The Corporation has strict underwriting, review, and monitoring procedures in place to mitigate this risk. Risk also lies in the residual value of the underlying equipment. Residual values are subject to judgments as to the value of the underlying equipment that can be affected by changes in economic and market conditions and the financial viability of the residual guarantors and insurers. To the extent not guaranteed or assumed by a third party, or otherwise insured against, the Corporation bears the risk of ownership of the leased assets. This includes the risk that the actual value of the leased assets at the end of the lease term will be less than the residual value. The Corporation greatly reduces this risk primarily by using $1.00 buyout leases, in which the entire cost of the leased equipment is included in the contractual payments, leaving no residual payment at the end of the lease term.

These loans are individually measured to determine the amount of potential impairment. The loans are reviewed for impairment based on the fair value of the collateral for collateral dependent loans and for certain loans based on discounted cash flows using the loans’ initial effective interest rates. Impaired loans included other accruing impaired loans of $23.3 million and $30.0 million at December 31, 2016 and 2015 , respectively. Specific reserves on other accruing impaired loans were $84 thousand and $186 thousand at December 31, 2016 and 2015 , respectively. The following presents by class of loans, the average recorded investment in impaired loans and an analysis of interest on impaired loans. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. Therefore, interest income on accruing impaired loans is recognized using the accrual method.

Any income accrued on 1-to-4 family residential properties after the loan becomes 90 days past due, which is not placed on non-accrual, is held in a reserve for uncollected interest. The reserve for uncollected interest was $10 thousand and $0 thousand at December 31, 2016 and 2015 , respectively. The Bank maintains a reserve in other liabilities for off-balance sheet credit exposures that currently are unfunded. The reserve for these off-balance sheet credits was $385 thousand and $381 thousand at December 31, 2016 and 2015 , respectively. Troubled Debt Restructured Loans The following presents, by class of loans, information regarding accruing and nonaccrual loans that were restructured during the years ended December 31, 2016 and 2015 : For the Years Ended December 31, 2016 2015 (Dollars in thousands) Number Pre- Post- Related Number Pre- Post- Related Accruing Troubled Debt Restructured Loans: Commercial, financial and agricultural 1 $ 1,545 $ 1,545 $ — 4 $ 1,140 $ 1,140 $ — Real estate—commercial real estate — — — — 1 405 405 — Real estate—residential secured for business purpose 1 415 415 — 1 353 353 — Total 2 $ 1,960 $ 1,960 $ — 6 $ 1,898 $ 1,898 $ — Nonaccrual Troubled Debt Restructured Loans: Commercial, financial and agricultural — $ — $ — $ — 1 $ 122 $ 122 $ 22 Real estate—residential secured for business purpose 1 313 312 — — — — — Real estate—residential secured for personal purpose 1 34 34 — — — — — Real estate—home equity secured for personal purpose 1 152 152 — — — — — Total 3 $ 499 $ 498 $ — 1 $ 122 $ 122 $ 22 The Corporation grants concessions primarily related to extensions of interest-only payment periods and an occasional payment modification. These modifications typically are for a short-term basis up to one year .

Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets The Corporation has covenants not to compete, core deposit and customer-related intangibles and mortgage servicing rights, which are not deemed to have an indefinite life and therefore will continue to be amortized over their useful life using the present value of projected cash flows. The amortization of intangible assets for the years ended December 31, 2016 , 2015 and 2014 was $4.1 million , $3.6 million and $3.3 million , respectively. In 2016 , 2015 and 2014 , impairment on customer-related intangibles was recognized in other noninterest expense in the amount of $0 thousand , $0 thousand and $31 thousand , respectively. The Corporation also has goodwill with a net carrying amount of $172.6 million at December 31, 2016 , which is deemed to be an indefinite intangible asset and is not amortized. The Corporation recorded goodwill of $59.9 million and core deposit intangibles of $5.3 million related to the Fox Chase Bank acquisition on July 1, 2016. In accordance with ASC Topic 350, the Corporation performed a qualitative assessment of goodwill during the fourth quarter of 2016 and determined it was more likely than not that the fair value of the Corporation, including each of the identified reporting units, was more than its carrying amount; therefore, the Corporation did not need to perform the two-step impairment test for the Corporation or the reporting units. The Corporation completed the most recent impairment test for goodwill during the fourth quarter of 2014. The Corporation also completed an impairment test for other intangible assets during the fourth quarter of 2016 . There was no goodwill impairment or material impairment of identifiable intangibles recorded during 2014 through 2016 .

The Corporation adopted ASU 2016-9, Improvements to Employee Share-Based Payment Accounting, which was issued in March 2016. All excess tax benefits and tax deficiencies for 2016 were recognized as a net income tax benefit in the statement of income. The additional paid-in capital pool was eliminated. The net impact of this adoption was $301 thousand in net income tax benefits recorded in the statement of income for the year ended December 31, 2016. Retained earnings include $6.0 million at December 31, 2016, 2015 and 2014, which was originally generated by Fox Chase Bank (acquired in 2016), for which no provision for federal income tax has been made. This amount represents deductions for bad debt reserves for tax purposes, which were only allowed to savings institutions that met certain criteria prescribed by the Internal Revenue Code of 1986, as amended. The Small Business Job Protection Act of 1996 (the "Act") eliminated the special bad debt deduction granted solely to thrifts. Under the terms of the Act, there would be no recapture of the pre-1988 (base year) reserves. However, these pre-1988 reserves would be subject to recapture under the rules of the Internal Revenue Code if the Company pays a cash dividend in excess of cumulative retained earnings or liquidates. At December 31, 2016 , the Corporation had no material unrecognized tax benefits, accrued interest or penalties. Penalties are recorded in noninterest expense in the year they are assessed and are treated as a non-deductible expense for tax purposes. Interest is recorded in noninterest expense in the year it is assessed and is treated as a deductible expense for tax purposes. At December 31, 2016 , the Corporation’s tax years 2013 through 2015 remain subject to federal examination as well as examination by state taxing jurisdictions. Deferred income taxes reflect the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred state taxes are combined with federal deferred taxes (net of the impact of deferred state tax on the deferred federal tax) and are shown in the table below by major category of deferred income or expense. The Corporation has a charitable contributions carryover of $606 thousand , resulting in a deferred tax asset of $212 thousand which will expire after December 31, 2021 , if not utilized. The Corporation has a state net operating loss carry-forward of $42.0 million which will begin to expire after December 31, 2018 if not utilized. A valuation allowance at December 31, 2016 and 2015 was attributable to deferred tax assets generated in certain state jurisdictions for which management believes it is more likely than not that such deferred tax assets will not be realized. Additionally, deferred tax assets of $42 thousand were reversed and recorded to additional paid-in capital during the year ended December 31, 2015 , as a result of unrecognized restricted stock and non-qualified stock option expense. During 2016, net deferred tax liabilities of $1.2 million were added due to the Fox Chase acquisition. The assets and liabilities giving rise to the Corporation’s deferred tax assets and liabilities are as follows: At December 31, (Dollars in thousands) 2016 2015 Deferred tax assets: Loan and lease loss $ 5,984 $ 6,012 Deferred compensation 2,541 2,483 Actuarial adjustments on retirement benefits* 7,714 8,525 State net operating losses 2,725 1,986 Other-than-temporary impairments on equity securities 331 317 Alternative minimum tax credits** 3,114 2,156 Net unrealized holding losses on securities available-for-sale and swaps* 2,762 472 Other deferred tax assets 2,676 3,209 Gross deferred tax assets 27,847 25,160 Valuation allowance (2,341 ) (1,609 ) Total deferred tax assets, net of valuation allowance 25,506 23,551 Deferred tax liabilities: Mortgage servicing rights 2,302 2,066 Retirement plans 6,265 6,307 Intangible assets 3,543 2,460 Depreciation 1,401 347 Other deferred tax liabilities 2,430 2,192 Total deferred tax liabilities 15,941 13,372 Net deferred tax assets $ 9,565 $ 10,179 * Represents the amount of deferred taxes recorded in accumulated other comprehensive loss. ** The alternative minimum tax credits have an indefinite life.

Retirement Plans and Other Postretirement Benefits	Retirement Plans and Other Postretirement Benefits Substantially all employees who were hired before December 8, 2009 are covered by a noncontributory retirement plan. Employees hired on or after December 8, 2009 are not eligible to participate in the noncontributory retirement plan. The Corporation also provides supplemental executive retirement benefits to certain former executives, a portion of which is in excess of limits imposed on qualified plans by federal tax law; these plans are non-qualified benefit plans. These non-qualified benefit plans are not offered to new participants; all current participants are now retired. Information on these plans are aggregated and reported under “Retirement Plans” within this footnote. The Corporation also provides certain postretirement healthcare and life insurance benefits for retired employees. Information on these benefits is reported under “Other Postretirement Benefits” within this footnote. The Corporation sponsors a 401(k) deferred salary savings plan, which is a qualified defined contribution plan, and which covers all employees of the Corporation and its subsidiaries, and provides that the Corporation makes matching contributions as defined by the plan. Expense recorded by the Corporation for the 401(k) deferred salary savings plan for the years ended December 31, 2016 , 2015 and 2014 was $1.2 million , $1.0 million , and $836 thousand , respectively. The Corporation sponsors a Supplemental Non-Qualified Pension Plan (SNQPP) which was established in 1981 prior to the existence of a 401(k) deferred salary savings plan, employee stock purchase plan and long-term incentive plans and therefore is not offered to new participants; all current participants are now retired. Expense recorded by the Corporation for the SNQPP for the years ended December 31, 2016 and 2015 was $52 thousand and $285 thousand , respectively. The Corporation recognized income in 2014 of $44 thousand primarily due to an increase in the weighted average discount rate from 4.0% for 2013 to 4.9% for 2014.

As a result, lump-sum payments from the plan were $3.2 million and exceeded the service cost and interest cost for the year triggering a settlement. The settlement was measured as of December 31, 2016 because the majority of lump sum payments occurred during December 2016. The settlement cost was $1.4 million . The amount represents a reclassification of accumulated other comprehensive income to pension expense (included in salaries and benefit expense in the statement of income) and had no impact on shareholders' equity.

Stock-Based Incentive Plan	Stock-Based Incentive Plan The Corporation has a shareholder approved 2013 Long-Term Incentive Plan which replaced the expired 2003 Long-Term Incentive Plan. Under the 2013 Long-Term Incentive Plan, the Corporation may grant options and share awards to employees and non-employee directors up to 3,355,786 shares of common stock, which includes 857,191 shares as a result of the completion of the acquisition of Fox Chase on July 1, 2016 and 473,483 shares as a result of the completion of the acquisition of Valley Green Bank on January 1, 2015. The number of shares of common stock available for issuance under the plan is subject to adjustment, as described in the plan. This includes, in the event of any merger, reorganization, consolidation, recapitalization, stock dividend, or other change in corporate structure affecting the stock, substitution or adjustment shall be made in the aggregate number of shares reserved for issuance under the plan, in the number and option price of shares subject to outstanding options granted under the plan and in the number and price of shares subject to other awards, as described in the plan. The plan provides for the issuance of options to purchase common shares at prices not less than 100 percent of the fair market value on the date of option grant and have a contractual term of ten years ; and for restricted stock awards valued at not less than 100 percent of the fair market value at the date of award grant. The options issued in 2016 become exercisable and vest at 33.3 percent per year for each of the following three years and remain exercisable for a period not exceeding ten years from the date of grant. For the majority of the restricted stock awards, the shares vest based upon the Corporation’s performance against selected peers with respect to certain financial measures over a three -year period. There were 2,747,871 share awards available for future grants at December 31, 2016 under the plan. At December 31, 2016 , there were 504,908 options to purchase common stock and 285,158 unvested restricted stock awards outstanding under the plan. The following table is a summary of the status of options under the Corporation’s long-term incentive plans: (Dollars in thousands, except per share data) Shares Under Option Weighted Average Exercise Price Per Share Weighted Average Remaining Contractual Life (Years) Aggregate Intrinsic Value at December 31, 2016 Outstanding at December 31, 2015 668,667 $ 18.88 Granted 160,312 19.73 Expired — — Forfeited (62,537 ) 18.93 Exercised (261,534 ) 19.04 Outstanding at December 31, 2016 504,908 19.06 6.2 $ 5,979 Exercisable at December 31, 2016 195,968 19.24 3.2 2,285 The following is a summary of nonvested stock options at December 31, 2016 including changes during the year: (Dollars in thousands, except per share data) Nonvested Stock Options Weighted Average Grant Date Fair Value Nonvested stock options at December 31, 2015 299,665 $ 5.91 Granted 160,312 6.23 Vested (88,500 ) 5.47 Forfeited (62,537 ) 6.16 Nonvested stock options at December 31, 2016 308,940 6.15 The total intrinsic value of options exercised during 2016 , 2015 , and 2014 was $2.1 million , $103 thousand , and $47 thousand , respectively. The Corporation has a stock-for-stock-option exchange (or cashless exercise) program in place, whereby optionees can exchange the value of the spread of in-the-money vested options for Corporation stock having an equivalent value. This broker-assisted exchange allows the optionees to exercise their vested options on a net basis without having to pay the exercise price or related expenses in cash. However, it will result in the optionees acquiring fewer shares than the number of options exercised. The Corporation's estimate of the fair value of a stock option is based on expectations derived from historical experience and may not necessarily equate to its market value when fully vested. The life of the option is based on historical factors which include the contractual term, vesting period, exercise behavior and employee turnover. The risk-free rate for periods within the expected term of the option is based on the U.S. Treasury strip rate in effect at the time of grant. Expected volatility is based on the historical volatility of the Corporation’s stock over the expected life of the grant. The Corporation uses a straight-line accrual method to recognize stock-based compensation expense over the time-period it expects the options to vest. The Corporation recognizes compensation expense for stock options over the requisite service period based on the grant-date fair value of those awards expected to ultimately vest. Forfeitures are estimated on the date of grant and revised if actual or expected forfeiture activity differs materially from original estimates. The following aggregated assumptions were used to estimate the fair value of options granted for the periods indicated: For the Years Ended December 31, 2016 2015 2014 Range Weighted Average Actual Actual Expected option life in years 7.6 - 8.2 7.9 8.0 8.2 Risk free interest rate 1.38% - 1.89% 1.87 % 1.64 % 2.51 % Expected dividend yield 3.80% - 4.19% 4.06 % 4.32 % 4.26 % Expected volatility 37.71% - 46.22% 45.82 % 49.38 % 50.16 % Fair value of options $5.40 - $6.27 $ 6.23 $ 6.07 $ 6.53 The following is a summary of nonvested restricted stock awards at December 31, 2016 including changes during the year: (Dollars in thousands, except per share data) Nonvested Share Awards Weighted Average Grant Date Fair Value Nonvested share awards at December 31, 2015 183,584 $ 18.00 Granted 176,255 20.60 Vested (51,272 ) 17.31 Forfeited (23,409 ) 17.86 Nonvested share awards at December 31, 2016 285,158 19.74 The fair value of restricted stock is equivalent to the fair value on the date of grant and is amortized over the vesting period.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Lending Operations The Corporation is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of customers. The Bank offers commercial, mortgage, and consumer credit products to customers in the normal course of business, which are detailed in Note 5. These products represent a diversified credit portfolio and are generally issued to borrowers within the Bank’s market area. Financial instruments with off-balance sheet risk include commitments to extend credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized on the consolidated balance sheets. The Corporation's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Collateral is obtained based on management’s credit assessment of the customer. Standby letters of credit commit the Bank to make payments on behalf of customers when certain specified future events occur. They are primarily issued to support commercial paper, medium and long-term notes and debentures, including industrial revenue obligations. The approximate term is usually one year but some can be up to five years . Historically, substantially all standby letters of credit expire unfunded. If funded, the majority of the letters of credit carry current market interest rates if converted to loans. Because letters of credit are generally un-assignable by either the Bank or the borrower, they only have value to the Bank and the borrower. The carrying amount is recorded as unamortized deferred fees and the exposure is considered in the reserve for credit risk. At December 31, 2016 , the maximum potential amount of future payments under letters of credit is $46.6 million . The current carrying amount of the contingent obligation is $208 thousand . This arrangement has credit risk essentially the same as that involved in extending loans to customers and is subject to the Bank’s normal credit policies. Collateral is obtained based on management’s credit assessment of the customer. The following schedule summarizes the Corporation’s off-balance sheet financial instruments at December 31, 2016 : (Dollars in thousands) Contract/Notional Amount Financial instruments representing credit risk: Commitments to extend credit $ 980,647 Performance letters of credit 26,570 Financial standby letters of credit 19,981 Other letters of credit 15 The Bank maintains a reserve in other liabilities for estimated losses associated with sold mortgages that may be repurchased. At December 31, 2016 , the reserve for sold mortgages was $284 thousand . Legal Proceedings Management is not aware of any litigation that would be probable of occurring or probable of having a material adverse effect on the Corporation’s consolidated balance sheet or statement of income. There are no proceedings pending other than the ordinary routine litigation incident to the business of the Corporation. In addition, there are no material proceedings pending or known to be threatened or contemplated against the Corporation or the Bank by government authorities. Operating Leases At December 31, 2016 , the Corporation and its subsidiaries were obligated under non-cancelable leases for various premises. Portions of certain properties are subleased.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities Interest Rate Swaps The Corporation may use interest-rate swap agreements to modify interest rate characteristics from variable to fixed or fixed to variable in order to reduce the impact of interest rate changes on future net interest income. Recorded amounts related to interest-rate swaps are included in other assets or liabilities. The Corporation’s credit exposure on interest rate swaps includes fair value and any collateral that is held by a third party. Changes in the fair value of derivative instruments designated as hedges of future cash flows are recognized in accumulated other comprehensive income until the underlying forecasted transactions occur, at which time the deferred gains and losses are recognized in earnings. For a qualifying fair value hedge, the gain or loss on the hedging instrument is recognized in earnings, and the change in fair value of the hedge item, to the extent attributable to the hedged risk, adjusts the carrying amount of the hedge item and is recognized in earnings. On October 24, 2014, the Corporation entered into an amortizing interest rate swap classified as a cash flow hedge with a notional amount of $20.0 million to hedge a portion of the debt financing of a pool of 10 -year maturity fixed rate loans with balances totaling $29.1 million , at time of the hedge, that were originated in 2013. A brokered money market demand account with a balance exceeding the amortizing interest rate swap balance is being used for the cash flow hedge. Under the terms of the swap agreement, the Corporation pays a fixed rate of 2.10% and receives a floating rate based on the one-month LIBOR . The swap matures in November 2022. The Corporation performed an assessment of the hedge for effectiveness at the inception of the hedge and on a recurring basis to determine that the derivative has been and is expected to continue to be highly effective in offsetting changes in cash flows of the hedged item. The Corporation expects that there will be no ineffectiveness over the life of the interest rate swap. At December 31, 2016 , approximately $196 thousand in net deferred losses, net of tax, recorded in accumulated other comprehensive loss are expected to be reclassified into earnings during the next twelve months. This amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to December 31, 2016 . At December 31, 2016 , the notional amount of the interest rate swap was $18.6 million , with a negative fair value of $217 thousand . The Corporation has an interest rate swap classified as a fair value hedge with a current notional amount of $1.4 million to hedge a 10 -year fixed rate loan that is earning interest at 5.83% . The Corporation pays a fixed rate of 5.83% and receives a floating rate based on the one-month LIBOR plus 350 basis points. The swap matures in October 2021. The difference between changes in the fair values of the interest rate swap agreement and the hedged loan represents hedge ineffectiveness and is recorded in other noninterest income in the consolidated statements of operations. The Corporation has an interest rate swap with a current notional amount of $622 thousand , for a 15 -year fixed rate loan that is earning interest at 7.43% . The Corporation pays a fixed rate of 7.43% and receives a floating rate based on the one-month LIBOR plus 224 basis points. The swap matures in April 2022. The interest rate swap is carried at fair value in accordance with FASB ASC 815 "Derivatives and Hedging." The loan is carried at fair value under the fair value option as permitted by FASB ASC 825 "Financial Instruments." Credit Derivatives The Corporation has agreements with third-party financial institutions whereby the third-party financial institution enters into interest rate derivative contracts and foreign currency swap contracts with loan customers referred to them by the Corporation. By the terms of the agreements, the third-party financial institution has recourse to the Corporation for any exposure created under each swap contract in the event the customer defaults on the swap agreement and the agreement is in a paying position to the third-party financial institution. These transactions represent credit derivatives and are a customary arrangement that allows the Corporation to provide access to interest rate and foreign currency swap transactions for customers without creating the swap. The Corporation records the fair value of credit derivatives in other liabilities on the consolidated balance sheets. The Corporation recognizes changes in the fair value of credit derivatives, net of any fees received, in other noninterest income in the consolidated statements of income. At December 31, 2016 , the Corporation (primarily through the acquisition of Fox Chase) has nine variable-rate to fixed-rate interest rate swap transactions between the third-party financial institution and customers with a current notional amount of $27.9 million , and remaining maturities ranging from two to 10 years. At December 31, 2016 , the fair value of the swaps to the customers was a liability of $9 thousand and all swaps were in paying positions to the third-party financial institution. At December 31, 2016 , there were no material foreign currency swap transactions between the third-party institution and loan customers. The maximum potential payments by the Corporation to the third-party financial institution under these credit derivatives are not estimable as they are contingent on future interest rates and exchange rates, and the agreement does not provide for a limitation of the maximum potential payment amount. Mortgage Banking Derivatives Derivative loan commitments represent agreements for delayed delivery of financial instruments in which the buyer agrees to purchase and the seller agrees to deliver, at a specified future date, a specified instrument at a specified price or yield. The Corporation’s derivative loan commitments are commitments to sell loans secured by 1-to 4-family residential properties whose predominant risk characteristic is interest rate risk. The fair values of these derivative loan commitments are based upon the estimated amount the Corporation would receive or pay to terminate the contracts or agreements, taking into account current interest rates and, when appropriate, the current creditworthiness of the counterparties. Derivatives Tables The following table presents the notional amounts and fair values of derivatives designated as hedging instruments recorded on the consolidated balance sheets at December 31, 2016 and 2015 . The Corporation pledges cash or securities to cover the negative fair value of derivative instruments.

Fair Value Disclosures

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Fair Value Disclosures Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The Corporation determines the fair value of financial instruments based on the fair value hierarchy. The Corporation maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Corporation. Unobservable inputs are inputs that reflect the Corporation’s assumptions that market participants would use in pricing the asset or liability based on the best information available in the circumstances, including assumptions about risk. Three levels of inputs are used to measure fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input significant to the fair value measurement. Transfers between levels are recognized at the end of the reporting period. Level 1: Valuations are based on quoted prices in active markets for identical assets or liabilities that the Corporation can access at the measurement date. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Level 2: Valuations are based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. Level 3: Valuations are based on inputs that are unobservable and significant to the overall fair value measurement. Assets and liabilities utilizing Level 3 inputs include: financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the fair value calculation requires significant management judgment or estimation. Following is a description of the valuation methodologies used for instruments measured at fair value on a recurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy. Investment Securities Where quoted prices are available in an active market for identical instruments, investment securities are classified within Level 1 of the valuation hierarchy. Level 1 investment securities include U.S. Treasury securities, most equity securities and money market mutual funds. Mutual funds are registered investment companies which are valued at net asset value of shares on a market exchange at the end of each trading day. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Examples of instruments, which would generally be classified within Level 2 of the valuation hierarchy, include securities issued by U.S. government sponsored enterprises, mortgage-backed securities, collateralized mortgage obligations, corporate and municipal bonds and certain equity securities. In cases where there is limited activity or less transparency around inputs to the valuation, investment securities are classified within Level 3 of the valuation hierarchy. Fair values for securities are determined using independent pricing services and market-participating brokers. The Corporation’s independent pricing service utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information for structured securities, cash flow and, when available, loan performance data. Because many fixed income securities do not trade on a daily basis, the pricing service’s evaluated pricing applications apply information as applicable through processes, such as benchmarking of like securities, sector groupings, and matrix pricing, to prepare evaluations. If at any time, the pricing service determines that it does have not sufficient verifiable information to value a particular security, the Corporation will utilize valuations from another pricing service. Management has a sufficient understanding of the third party service’s valuation models, assumptions and inputs used in determining the fair value of securities to enable management to maintain an appropriate system of internal control. Certain corporate securities owned by the Corporation are classified as Level 3 as they are not traded in active markets.The fair value of each security is estimated by benchmarking similar transactions of structure, yield and credit which are owned by the Corporation and are actively traded in the market. On a quarterly basis, the Corporation reviews changes, as submitted by the pricing service, in the market value of its security portfolio. Individual changes in valuations are reviewed for consistency with general interest rate movements and any known credit concerns for specific securities. If, upon the Corporation’s review or in comparing with another service, a material difference between pricing evaluations were to exist, the Corporation may submit an inquiry to the current pricing service regarding the data used to determine the valuation of a particular security. If the Corporation determines there is market information that would support a different valuation than from the current pricing service’s evaluation, the Corporation may utilize and change the security's valuation. There were no material differences in valuations noted at December 31, 2016 . Derivative Financial Instruments The fair values of derivative financial instruments are based upon the estimated amount the Corporation would receive or pay to terminate the contracts or agreements, taking into account current interest rates and, when appropriate, the current creditworthiness of the counterparties. Interest rate swaps and mortgage banking derivative financial instruments are classified within Level 2 of the valuation hierarchy. Credit derivatives are valued based on credit worthiness of the underlying borrower which is a significant unobservable input and therefore classified in Level 3 of the valuation hierarchy. Two commercial loans, associated with interest rate swaps are classified in Level 3 of the valuation hierarchy since lending credit risk is not an observable input for these loans. The unrealized gain on the two loans was $97 thousand at December 31, 2016 . Contingent Consideration Liability The Corporation estimates the fair value of the contingent consideration liability by using a discounted cash flow model of future contingent payments based on projected revenue related to the acquired business. The estimated fair value of the contingent consideration liability is reviewed on a quarterly basis and any valuation adjustments resulting from a change of estimated future contingent payments based on projected revenue of the acquired business affecting the contingent consideration liability will be recorded through noninterest expense. Changes in the original assumptions utilized at the time the acquisition closes and identified during the measurement period are recorded in accordance with ASC Topic 805 as an adjustment to goodwill. Due to the significant unobservable input related to the projected revenue, the contingent consideration liability is classified within Level 3 of the valuation hierarchy. An increase in the projected revenue may result in a higher fair value of the contingent consideration liability. Alternatively, a decrease in the projected revenue may result in a lower estimated fair value of the contingent consideration liability. For the Sterner Insurance Associates acquisition, the potential remaining cash payments that could result from the contingent consideration arrangement range from $0 to a maximum of $2.6 million based on the results for the twelve -month period June 30, 2017 . Due to updates to the original assumptions utilized for determining the contingent consideration liability for the Sterner acquisition completed on July 1, 2014, the Corporation recorded a purchase accounting adjustment, in accordance with ASC Topic 805, in the first quarter of 2015 which resulted in an increase to the contingent consideration liability and an increase to goodwill of $1.5 million . During the fourth quarter of 2016, the Corporation reached an agreement to settle its future obligations related to the Girard Partners acquisition. The total settlement amount of $5.3 million was paid during the first quarter of 2017; additional amortization of $2.1 million was recognized in noninterest expense in 2016. During 2015, the Corporation recorded a reduction to the contingent liability which resulted in a reduction of noninterest expense of $550 thousand . The adjustment reflected that projected revenue levels for earn-out payments in the second through fifth years post-acquisition were anticipated to be lower than originally projected.

Cash and short-term interest-earning assets are classified within Level 1 in the fair value hierarchy. Held-to-maturity securities: Fair values for the held-to-maturity investment securities are estimated by using pricing models or quoted prices of securities with similar characteristics and are classified in Level 2 in the fair value hierarchy. Federal Home Loan Bank, Federal Reserve Bank and other stock: It is not practical to determine the fair values of Federal Home Loan Bank, Federal Reserve Bank and other stock, due to restrictions placed on their transferability. Loans held for sale: The fair value of the Corporation’s mortgage loans held for sale are generally determined using a pricing model based on current market information obtained from external sources, including interest rates, bids or indications provided by market participants on specific loans that are actively marketed for sale. These loans are primarily residential mortgage loans and are generally classified in Level 2 due to the observable pricing data. Loans held for sale are carried at the lower of cost or estimated fair value. There were no valuation adjustments for loans held for sale at December 31, 2016 and 2015 . Loans and leases held for investment: The fair values for loans and leases held for investment are estimated using discounted cash flow analyses, using a discount rate based on current interest rates at which similar loans with similar terms would be made to borrowers and include components for credit risk, operating expense and embedded prepayment options. An overall valuation adjustment is made for specific credit risks in addition to general portfolio risk and is significant to the valuation. As permitted, the fair value of the loans and leases are not based on the exit price concept as discussed in the first paragraph of this note. Loans and leases are classified within Level 3 in the fair value hierarchy since credit risk is not an observable input. Impaired loans held for investment: Impaired loans held for investment include those collateral-dependent loans for which the practical expedient was applied, resulting in a fair-value adjustment to the loan. Impaired loans are evaluated and valued at the time the loan is identified as impaired, at the lower of cost or fair value. Fair value is measured based on the value of the collateral securing these loans less costs to sell and is classified at a Level 3 in the fair value hierarchy. The fair value of collateral is based on appraisals performed by qualified licensed appraisers hired by the Corporation. At December 31, 2016 , impaired loans held for investment had a carrying amount of $43.9 million with a valuation allowance of $235 thousand . At December 31, 2015 , impaired loans held for investment had a carrying amount of $48.9 million with a valuation allowance of $322 thousand . Mortgage servicing rights: The Corporation estimates the fair value of mortgage servicing rights using discounted cash flow models that calculate the present value of estimated future net servicing income. The model uses readily available prepayment speed assumptions for the interest rates of the portfolios serviced. Mortgage servicing rights are classified within Level 3 in the fair value hierarchy based upon management’s assessment of the inputs. The Corporation reviews the mortgage servicing rights portfolio on a quarterly basis for impairment and the mortgage servicing rights are carried at the lower of amortized cost or estimated fair value. At December 31, 2016 and December 31, 2015 , mortgage servicing rights had a carrying amount of $6.5 million and $5.9 million , respectively, with no valuation allowance. Goodwill and other identifiable assets: Certain non-financial assets subject to measurement at fair value on a non-recurring basis include goodwill and other identifiable intangible assets. In accordance with ASC Topic 350, the Corporation performed a qualitative assessment of goodwill during the fourth quarter of 2016 and determined it was more likely than not that the fair value of the Corporation, including each of the identified reporting units, was more than its carrying amount; therefore, the Corporation did not need to perform the two-step impairment test for the Corporation or the reporting units. The Corporation also completed an impairment test for other intangible assets during the fourth quarter of 2016 . There was no impairment of goodwill or identifiable intangibles recorded. Other real estate owned: The fair value of other real estate owned (OREO) is originally estimated based upon the appraised value less estimated costs to sell. The fair value less cost to sell becomes the "original cost" of the OREO asset. Subsequently, OREO is reported as the lower of the original cost and the current the fair value less cost to sell. Capital improvement expenses associated with the construction or repair of the property are capitalized as part of the cost of the OREO asset; however, the capitalized expenses may not increase the OREO asset's recorded value to an amount greater than the asset's fair value after improvements and less cost to sell. New appraisals are generally obtained on an annual basis. During 2016 , four properties had write-downs totaling $469 thousand which was included in other noninterest income in the statement of income. Other real estate owned is classified within Level 3 of the valuation hierarchy due to the unique characteristics of the collateral for each loan. Deposit liabilities: The fair values for demand and savings accounts, with no stated maturities, is the amount payable on demand at the reporting date (carrying value) and are classified within Level 1 in the fair value hierarchy. The fair values for time deposits with fixed maturities are estimated by discounting the final maturity using interest rates currently offered for deposits with similar remaining maturities. Time deposits are classified within Level 2 in the fair value hierarchy. Short-term borrowings: The fair value of customer repurchase agreements and federal funds purchased are estimated using current market rates for similar borrowings and are classified within Level 2 in the fair value hierarchy. Long-term debt: The fair value of long-term debt is estimated by using discounted cash flow analysis, based on current market rates for debt with similar terms and remaining maturities. Long-term debt is classified within Level 2 in the fair value hierarchy. Subordinated notes: The fair value of subordinated notes are estimated by discounting the principal balance using the treasury yield curve for the term to the call date as the Corporation has the option to call the subordinated notes. The subordinated notes are classified within Level 2 in the fair value hierarchy. Off-balance-sheet instruments: Fair values for the Corporation’s off-balance-sheet instruments are based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing and are classified within Level 2 in the fair value hierarchy.

Restructuring and Related Activities [Abstract]
Restructuring Charges	Restructuring Charges During the first quarter of 2015, the Corporation finalized a new financial center model, which is smaller in size, combines enhanced technology with personal service and provides consultive services and solutions delivered by personal bankers. These efforts have led to the development of a comprehensive financial center optimization plan approved in April 2015 which includes opening new financial centers in growth markets while closing financial centers which operate in close proximity to other centers. As the Corporation announced in April 2015, six financial centers were closed in September 2015 that operated in close proximity to other centers. As a result, the Corporation recorded $1.6 million in restructuring charges during the second quarter of 2015 and related to the Banking business segment. The Corporation negotiated more favorable lease termination agreement on two of the properties during 2016 resulting in a reversal in the accrual of $152 thousand . During the third and fourth quarters of 2016, the Corporation exited four financial centers, a lease for a new financial center and two administrative offices, and reduced staff due to rationalization; resulting in accruing a loss of $1.9 million related to the Banking business segment. As a result of the Fox Chase acquisition and in an effort to optimize market visibility, financial centers and administrative offices which operated in close proximity to other centers were analyzed and staffing was rationalized. A roll-forward of the accrued restructuring expense is as follows: (Dollars in thousands) Severance expenses Write-downs and retirements of fixed assets Lease cancellations Total Accrued at January 1, 2016 $ — $ 228 $ 834 $ 1,062 Restructuring charges 1,207 409 115 1,731 Payments (306 ) — (868 ) (1,174 ) Accelerated depreciation — (409 ) — (409 ) Accrued at December 31, 2016 $ 901 $ 228 $ 81 $ 1,210

Regulatory Matters

Regulatory Matters	12 Months Ended

Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters The Corporation and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. The risk-based capital guidelines include both a definition of capital and a framework for calculating risk-weighted assets by assigning balance sheet assets and off-balance sheet items to broad risk categories. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Corporation’s and the Bank’s financial statements. Capital adequacy guidelines, and additionally for the Bank the prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weighting and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Corporation and the Bank to maintain minimum amounts and ratios (set forth in the following table) of Total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined), or leverage ratio. In July 2013, the federal bank regulatory agencies adopted final rules revising the agencies’ capital adequacy guidelines and prompt corrective action rules, designed to enhance such requirements and implement the revised standards of the Basel Committee on Banking Supervision, commonly referred to as Basel III. The new minimum capital requirements were effective on January 1, 2015. Under the new rules, in order to avoid limitations on capital distributions (including dividend payments and certain discretionary bonus payments to executive officers), a banking organization must hold a capital conservation buffer comprised of common equity Tier 1 capital above its minimum risk-based capital requirements in an amount greater than 2.5% of total risk-weighted assets. The capital conservation buffer requirements phase in over a four -year period beginning January 1, 2016. The Corporation adopted the new Basel III regulatory capital rules during the first quarter of 2015 under the transition rules, primarily relating to regulatory deductions and adjustments impacting common equity tier 1 capital and tier 1 capital, to be phased in over a three -year period beginning January 1, 2015 . Under Basel III rules, the decision was made to opt-out of including accumulated other comprehensive income in regulatory capital. During 2016, the Corporation and the Bank were required to hold a capital conservation buffer greater than 0.625% above its minimum risk-based capital requirements in order to avoid limitations on capital distributions. During 2017, the Corporation and the Bank must hold a capital conservation buffer greater than 1.25% above its minimum risk-based capital requirements in order to avoid limitations on capital distributions. The Corporation's and Bank's actual and required capital ratios as of December 31, 2016 and December 31, 2015 under BASEL III regulatory capital rules were as follows. (Dollars in thousands) Actual For Capital Adequacy To Be Well-Capitalized Amount Ratio Amount Ratio Amount Ratio At December 31, 2016 Total Capital (to Risk-Weighted Assets): Corporation $ 462,198 12.44 % $ 297,284 8.00 % $ 371,604 10.00 % Bank 436,435 11.85 294,679 8.00 368,349 10.00 Tier 1 Capital (to Risk-Weighted Assets): Corporation 349,942 9.42 222,963 6.00 297,284 8.00 Bank 418,266 11.36 221,010 6.00 294,679 8.00 Tier 1 Common Capital (to Risk-Weighted Assets): Corporation 349,942 9.42 167,222 4.50 241,543 6.50 Bank 418,266 11.36 165,757 4.50 239,427 6.50 Tier 1 Capital (to Average Assets): Corporation 349,942 8.84 158,410 4.00 198,013 5.00 Bank 418,266 10.64 157,254 4.00 196,567 5.00 At December 31, 2015 Total Capital (to Risk-Weighted Assets): Corporation $ 334,757 13.35 % $ 200,613 8.00 % $ 250,766 10.00 % Bank 300,527 12.09 198,816 8.00 248,521 10.00 Tier 1 Capital (to Risk-Weighted Assets): Corporation 267,098 10.65 150,460 6.00 200,613 8.00 Bank 282,245 11.36 149,112 6.00 198,816 8.00 Tier 1 Common Capital (to Risk-Weighted Assets): Corporation 267,098 10.65 112,845 4.50 162,998 6.50 Bank 282,245 11.36 111,834 4.50 161,538 6.50 Tier 1 Capital (to Average Assets): Corporation 267,098 9.69 110,227 4.00 137,783 5.00 Bank 282,245 10.31 109,480 4.00 136,850 5.00 At December 31, 2016 and December 31, 2015 , management believes that the Corporation and the Bank continued to meet all capital adequacy requirements to which they are subject. The Corporation, like other bank holding companies, currently is required to maintain Tier 1 Capital and Total Capital equal to at least 6.0% and 8.0%, respectively, of its total risk-weighted assets (including various off-balance-sheet items). The Bank, like other depository institutions, is required to maintain similar capital levels under capital adequacy guidelines. During 2016, the Corporation and the Bank was required to hold a capital conservation buffer comprised of common equity Tier I capital above its minimum risk-based capital requirements in an amount greater than .625% of total risk-weighted assets in order to avoid limitations on capital distributions. For a depository institution to be considered “well capitalized” under the regulatory framework for prompt corrective action, Tier 1 and Total Capital ratios must be at least 8.0% and 10.0% on a risk-adjusted basis, respectively. At December 31, 2016 , the Bank is categorized as “well capitalized” under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank’s category. The Corporation will continue to analyze the impact of the new rules as it grows and as the capital conservation buffer requirements are phased in. Dividends and Other Restrictions The primary source of the Corporation’s dividends paid to its shareholders is from the earnings of the Bank paid to the Corporation in the form of dividends. The approval of the Federal Reserve Board of Governors is required for a state bank member in the Federal Reserve system to pay dividends if the total of all dividends declared in any calendar year exceeds the Bank’s net profits (as defined) for that year combined with its retained net profits for the preceding two calendar years. Under this formula, the Bank can declare dividends in 2017 without approval of the Federal Reserve Board of Governors of approximately $16.1 million plus an additional amount equal to the Bank’s net profits for 2017 up to the date of any such dividend declaration. Federal Reserve Board policy applicable to the holding company also provides that, as a general matter, a bank holding company should inform the Federal Reserve and should eliminate, defer or significantly reduce the holding company’s dividends if the holding company’s net income for the preceding four quarters, net of dividends paid during the period, is not sufficient to fully fund the dividends, the holding company’s prospective rate of earnings retention is inconsistent with capital needs and overall current and prospective financial condition, or the holding company will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios. Federal Reserve Board policy also provides that a bank holding company should inform the Federal Reserve reasonably in advance of declaring or paying a dividend that exceeds earnings for the period or that could result in a material adverse change to the organization’s capital structure. The Federal Reserve Act requires that the extension of credit by the Bank to certain affiliates, including the Corporation (parent), be secured by readily marketable securities, that the extension of credit to any one affiliate be limited to 10% of the Bank’s capital and surplus (as defined), and that extensions of credit to all such affiliates be limited to 20% of the Bank’s capital and surplus.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting At December 31, 2016 , the Corporation has three reportable business segments: Banking, Wealth Management and Insurance. The Corporation determines the segments based primarily upon product and service offerings, through the types of income generated and the regulatory environment. This is strategically how the Corporation operates and has positioned itself in the marketplace. Accordingly, significant operating decisions are based upon analysis of each of these segments. The parent holding company and intercompany eliminations are included in the "Other" segment. The Corporation's Banking segment consists of commercial and consumer banking. The Wealth Management segment consists of investment advisory services, retirement plan services, trust, municipal pension services and broker/dealer services. The Insurance segment consists of commercial lines, personal lines, benefits and human resources consulting. Each segment generates revenue from a variety of products and services it provides. Examples of products and services provided for each reportable segment are indicated below. Ÿ The Banking segment provides financial services to consumers, businesses and governmental units. These services include a full range of banking services such as deposit taking, loan origination and servicing, mortgage banking, other general banking services and equipment lease financing. Ÿ The Wealth Management segment offers trust and investment advisory services, guardian and custodian of employee benefits and other trust and brokerage services, as well as a registered investment advisory managing private investment accounts for both individuals and institutions. Ÿ The Insurance segment includes a full-service insurance brokerage agency offering commercial property and casualty insurance, group life and health coverage, employee benefit solutions, personal insurance lines and human resources consulting. The accounting policies, used in the disclosure of the operating segments, are the same as those described in Note 1, “Summary of Significant Accounting Policies."

Summary of Significant Accoun34

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Organization	Organization Univest Corporation of Pennsylvania (the Corporation) through its wholly owned subsidiary, Univest Bank and Trust Co. (the Bank), is engaged in domestic commercial and consumer banking services and provides a full range of banking and trust services to its customers. The Bank wholly owns Univest Capital, Inc., which provides lease financing, and Delview, Inc., who through its subsidiaries, Univest Investments, Inc., Univest Insurance, Inc. and Girard Partners provides financial planning, investment management, investment advisory, insurance products and brokerage services. Univest Investments, Inc., Univest Insurance, Inc. and Univest Capital, Inc. were formed to enhance the traditional banking and trust services provided by the Bank, along with the acquisition of Girard Partners. At December 31, 2016 , the Corporation has three reportable business segments: Banking, Wealth Management and Insurance. The Corporation determines its segments based primarily upon product and service offerings, through the types of income generated and the regulatory environment. This is strategically how the Corporation operates and has positioned itself in the marketplace. Accordingly, significant operating decisions are based upon analysis of each of these segments. For more detailed discussion and financial information on the business segments, see Note 23 “Segment Reporting.” The Bank serves Montgomery, Bucks, Chester, Philadelphia, Lancaster and Lehigh Counties of Pennsylvania and Cape May County in New Jersey through thirty-seven banking offices and provides banking and trust services to the residents and employees of fourteen retirement communities.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Corporation and its wholly owned subsidiaries; the Corporation’s primary subsidiary is the Bank. All significant intercompany balances and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current-year presentation.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include fair value measurement of investment securities available-for-sale and assessment for impairment of certain investment securities, reserve for loan and lease losses, valuation of goodwill and other intangible assets, mortgage servicing rights, deferred tax assets and liabilities, benefit plans and stock-based compensation expense.
Interest-earning Deposits with Other Banks	Interest-earning Deposits with Other Banks Interest-earning deposits with other banks consist of deposit accounts with other financial institutions generally having maturities of three months or less. At times, such balances exceed the FDIC limits for insurance coverage.
Investment Securities	Investment Securities Securities are classified as investment securities held-to-maturity and carried at amortized cost if management has the positive intent and ability to hold the securities to maturity. Securities purchased with the intention of recognizing short-term profits are placed in the trading account and are carried at fair value. The Corporation did not have any trading account securities at December 31, 2016 or 2015 . Securities not classified as held-to-maturity or trading are designated securities available-for-sale and carried at fair value with unrealized gains and losses, net of estimated income taxes, reflected in accumulated other comprehensive income, a separate component of shareholders' equity. Securities classified as available-for-sale are those securities that the Corporation intends to hold for an indefinite period of time but not necessarily to maturity. Any decision to sell a security classified as available-for-sale would be based on various factors, including interest rates, changes in the maturity or mix of the Corporation's assets and liabilities, liquidity needs, regulatory capital considerations and other factors. Management determines the appropriate classification of debt securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Purchase premiums and discounts are recognized in interest income using the interest method over the expected life of the securities. Due to volatility in the financial markets, there is the risk that any future fair value could vary from that disclosed in the accompanying financial statements. Realized gains and losses on the sale of investment securities are recorded on the trade date, determined using the specific identification method and are included in the consolidated statements of income. Management evaluates debt securities, which are comprised of U.S. government, government sponsored agencies, municipalities, corporate bonds and other issuers, for other-than-temporary impairment by considering the current economic conditions, the length of time and the extent to which the fair value has been less than cost, market interest rates and the credit rating of each security. Unrealized losses on the Corporation’s investments in debt securities that are deemed in debt securities are temporary in nature are recognized in other comprehensive income, net of tax. Should it be determined that a security is impacted by deteriorating credit, the credit portion of the loss is recognized in earnings. The Corporation does not have the intent to sell the debt securities and believes it is more likely than not, that it will not have to sell the securities before recovery of their cost basis. The Corporation evaluates its equity securities for other-than-temporary impairment. Other-than-temporary impairment charges are recorded when the Corporation determines the fair value of certain equity securities will not recover the cost basis of the individual security within a reasonable period of time due to a decline in the financial stability of the underlying companies. Management evaluates the near-term prospects of the issuers in relation to the severity and duration of the impairment. The Corporation has the intent and ability to hold these securities until recovery of the Corporation’s cost basis occurs.
Federal Home Loan Bank Stock, Federal Reserve Bank Stock and Certain Other Investments without Readily Determinable Fair Values	Federal Home Loan Bank Stock, Federal Reserve Bank Stock and Certain Other Investments without Readily Determinable Fair Values At December 31, 2016 and 2015 , the Bank held $14.6 million and $6.6 million , respectively, in Federal Reserve Bank stock as required by the Federal Reserve Bank. The Bank is a member of the FHLB, and as such, is required to hold FHLB stock as a condition of membership as determined by the FHLB. The Bank is required to hold additional stock in the FHLB in relation to the level of outstanding borrowings. The Bank held FHLB stock of $10.1 million and $2.2 million at December 31, 2016 and 2015 , respectively. Additionally, the FHLB might require its members to increase their capital stock investments. Changes in the credit ratings of the U.S. government and federal agencies, including the FHLB, could increase the borrowing costs of the FHLB and possibly have a negative impact on its operations and long-term performance. It is possible this could have an adverse effect on the value of the Corporation’s investment in FHLB stock. Because ownership is restricted, the fair values of these investments are not readily determinable. As such, these investments are recorded at cost and evaluated for other-than-temporary impairment. The Corporation determined there was no other-than-temporary impairment of its investments in these stocks at December 31, 2016 or 2015 .
Loans Held For Sale	Loans Held for Sale The Corporation originates mortgage loans for investment and for sale. At origination, a mortgage loan is identified as either for sale or for investment. Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value. Net unrealized losses are recognized by charges to non-interest income. Cash payments and cash receipts resulting from acquisitions and sales of loans are classified as operating cash flows if those loans are acquired specifically for resale. Cash receipts resulting from sales of loans that were not specifically acquired for resale are classified as investing cash inflows regardless of a change in the purpose for holding those loans.
Loans and Leases	Loans and Leases Loans and leases are stated at the principal amount less net deferred fees and unearned discount. Interest income on commercial loans, real estate loans excluding residential real estate loans, and consumer loans is recorded on the outstanding balance method, using actual interest rates applied to daily principal balances. Interest on residential real estate loans is recorded based on the outstanding balance using the actual interest rate based upon a monthly interest calculation. Loan commitments are made to accommodate the financial needs of the customers. These commitments represent off-balance sheet items that are unfunded. The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet financial instruments. Accrual of interest income on loans and leases ceases when collectability of interest and/or principal is questionable. If it is determined that the collection of interest previously accrued is uncertain, such accrual is reversed and charged to current earnings. Loans and leases are considered past due based upon failure to comply with contractual terms. A loan or lease is typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest, even though the loan or lease is currently performing. When a loan or lease, including a loan or lease that is impaired, is classified as nonaccrual, the accrual of interest on such a loan or lease is discontinued. A loan or lease may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan or lease is placed on nonaccrual status, unpaid interest credited to income is reversed and the amortization of the net deferred fees is suspended. Interest payments received on nonaccrual loans and leases are either applied against principal or reported as interest income, according to management’s judgment as to the ultimate collectability of principal. Loans and leases are usually restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. A loan or lease is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the loan agreement or when a loan or lease is classified as a troubled debt restructuring. Interest on impaired loans and leases, which are not classified as nonaccrual, is recognized on the accrual basis.
Acquired Loans	Acquired Loans Acquired loan portfolios are initially recorded at the acquisition date fair value. The fair value is based on guidance which defines fair value as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Level 3 inputs are utilized to value the portfolio and include the use of present value techniques employing cash flow estimates and incorporate assumptions that marketplace participants would use in estimating fair values. In instances where reliable market information is not available, the Corporation uses assumptions in an effort to determine reasonable fair value. Specifically, management utilizes three separate fair value analyses which a market participant would employ in estimating the total fair value adjustment. The three separate fair valuation methodologies used are: 1) interest rate loan fair value analysis; 2) general credit fair value analysis; and 3) specific credit fair value analysis. There is no carryover related allowance for loan losses. For loans acquired without evidence of credit quality deterioration, the fair value adjustments to reflect the fair value of the loans and the fair value adjustments to reflect the general credit risk of the loan portfolio are substantially recognized as interest income on a level yield amortization method based upon the expected life of the loan. Subsequent to the acquisition, the Corporation records a provision for loan loss for the acquired non-impaired loans only when additional deterioration of the portfolio is identified over the projections utilized in the initial fair value analysis. For loans acquired with evidence of credit quality deterioration , the Corporation prepares a specific credit fair value adjustment. Management reviews the acquired loan portfolio for loans meeting the definition of an impaired loan with deteriorated credit quality. Loans meeting this definition are reviewed by comparing the contractual cash flows to expected collectible cash flows. The aggregate expected cash flows less the acquisition date fair value results in an accretable yield amount. The accretable discount amount is recognized over the life of the loans on a level yield basis as an adjustment to yield. Any disposals of loans, including sales of loans, payments in full or foreclosures result in the derecognition of the loan at its carrying value with differences in actual results reflected in interest income. After the acquisition measurement period, the present value of any decreases in expected cash flows of purchased impaired loans will generally result in an impairment charge recorded as a provision for loan loss, resulting in an increase to the allowance.
Loan and Lease Fees	Loan and Lease Fees Fees collected upon loan or lease origination and certain direct costs of originating loans and leases are deferred and recognized over the contractual lives of the related loans and leases as yield adjustments using the interest method. Upon prepayment or other disposition of the underlying loans and leases before their contractual maturities, any associated unearned fees or unamortized costs are recognized.
Reserve for Loan and Lease Losses	Reserve for Loan and Lease Losses The reserve for loan and lease losses is maintained at a level representing management's best estimate of known risks and inherent losses in the portfolio, based upon management's evaluation of the portfolio's collectability. Management evaluates the need to establish reserves against losses on loans on a quarterly basis. When changes in the reserve are necessary, an adjustment is made. The reserve for loan and lease losses is adjusted through provisions for loan and lease losses charged against or credited to income. Loans deemed to be uncollectible are charged against the reserve for loan and lease losses, and any subsequent recoveries are credited to the reserve. Reserve Required for Impaired Loans and Leases A loan or lease is considered impaired when, based on current information and events, it is probable that the Bank will be unable to collect future payments of principal or interest as contractually due. The Bank applies its normal loan review procedures in determining if a loan is impaired, which includes reviewing the collectability of delinquent and internally classified loans on a regular basis and at least quarterly. In determining the likelihood of collecting principal and interest, the Bank considers all available and relevant information, including the borrower's actual and projected cash flows, balance sheet strength, liquidity and overall financial position. Additionally, all loans classified as a troubled debt restructurings are considered impaired. When a loan is classified as impaired, an impairment analysis is performed within the quarter in which a loan is identified as impaired to determine if a valuation allowance is needed. The Bank re-examines each impaired loan on a quarterly basis to determine if any adjustment to the net carrying amount of a loan is required. The Bank recognizes charge-offs associated with impaired loans when all or a portion of a loan is considered to be uncollectible. In measuring impairment, the Bank determines whether or not the loan is collateral dependent. A loan is collateral dependent if repayment is expected to be provided solely by the underlying collateral, which includes repayment from the proceeds from the sale of the collateral, cash flows from the continued operation of the collateral, or both, and there are no other available and reliable repayment sources. To determine the initial amount of impairment for a collateral dependent loan, the Bank utilizes a recent appraisal, an agreement of sale or a letter of intent. If the fair value of the underlying collateral, less costs to sell, is less than the loan's carrying amount, the Bank establishes a provision to the reserve for loan and lease losses in the amount of the difference between fair value, less costs to sell, and the loan or lease's carrying amount. In subsequent periods, the Bank takes into consideration current facts and circumstances in analyzing whether the fair value of the collateral has increased or decreased significantly such that a change to the corresponding valuation allowance is required. If current facts and circumstances are insufficient to determine fair value, the Bank obtains a new appraisal. For loans that are not collateral dependent, the Bank establishes a specific reserve on impaired loans based on management's estimate of the discounted cash flows the Bank expects to receive from the borrower. Factors considered in evaluating such cash flows include: (1) the strength of the customer's personal or business cash flows and personal guarantees; (2) the borrower's effort to cure the delinquency; (3) the availability of other sources of repayment; (4) the type and value of collateral, if applicable; and (5) the strength of our collateral position, if applicable. General Reserve on the Remainder of the Portfolio The Bank establishes a general reserve for loans and leases that are not considered impaired to recognize the inherent losses associated with lending activities. This general reserve is determined by segmenting the loan portfolio and assigning reserve factors to each category. The reserve factors are calculated using the Bank's historical losses and loss emergence periods, and are adjusted for significant factors that, in management's judgment, affect the collectability of the portfolio as of the evaluation date. These significant factors include: • Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off and recovery practices not considered elsewhere in estimating credit losses; • Changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments; • Changes in the nature and volume of the portfolio and in the terms of loans; • Changes in the experience, ability, and depth of lending management and other relevant staff; • Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans; • Changes in the quality of the institution’s loan review system; • Changes in the value of underlying collateral for collateral-dependent loans; • The existence and effect of any concentrations of credit, and changes in the level of such concentrations; and • The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the institution’s existing portfolio. The Corporation maintains a reserve in other liabilities for off-balance sheet credit exposures that currently are unfunded in categories with historical loss experience. In addition, the Bank's primary examiner, as a regular part of their examination process, may require the Bank to increase the level of reserves.
Premises and Equipment	Premises and Equipment Land is stated at cost, and premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method and charged to operating expenses over the estimated useful lives of the assets or, for leasehold improvements, over the life of the related lease if less than the estimated useful life of the asset. The estimated useful life for new buildings constructed on land owned is forty years , and for new buildings constructed on leased land, is the lesser of forty years or the lease term including anticipated renewable terms. The useful life of purchased existing buildings is the estimated remaining useful life at the time of the purchase. Land improvements are considered to have estimated useful lives of fifteen years or the lease term including anticipated renewable terms. Furniture, fixtures and equipment have estimated useful lives ranging from three to ten years.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets The Corporation accounts for its acquisitions using the purchase accounting method. Purchase accounting requires the total purchase price to be allocated to the estimated fair values of assets acquired and liabilities assumed, including certain intangible assets that must be recognized. Typically, this allocation results in the purchase price exceeding the fair value of net assets acquired, which is recorded as goodwill. Core deposit intangibles are a measure of the value of checking, money market and savings deposits acquired in business combinations accounted for under the purchase method. Core deposit intangibles are amortized using the sum of the year’s digits over their estimated useful lives of up to fifteen years . Customer related intangibles are amortized over their estimated useful lives of five to twelve years. Covenants not to compete are amortized over their three to five -year contractual lives on a straight-line basis. The Corporation completes a goodwill analysis at least on an annual basis or more often if events and circumstances indicate that there may be impairment. The Corporation also completes an impairment test for other intangible assets on an annual basis or more often if events and circumstances indicate a possible impairment. There can be no assurance that future impairment analyses will not result in a charge to earnings. Mortgage servicing rights are recognized as separate assets when mortgage loans are sold and the servicing rights are retained. Capitalized mortgage servicing rights are reported in other intangible assets on the consolidated balance sheets and are amortized into noninterest income in proportion to, and over the period of, estimated net servicing income on a basis similar to the interest method and an accelerated amortization method for loan payoffs. Mortgage servicing rights are evaluated for impairment, on a quarterly basis, based upon the fair value of the servicing rights as compared to amortized cost. The Corporation estimates the fair value of mortgage servicing rights using discounted cash flow models that calculate the present value of estimated future net servicing income. The model uses readily available prepayment speed assumptions for the current interest rates of the portfolios serviced. Mortgage servicing rights are carried at the lower of amortized cost or estimated fair value. Impairment is recognized through a valuation allowance, to the extent that fair value is less than the unamortized capitalized amoun
Bank Owned Life Insurance	Bank Owned Life Insurance The Corporation has invested in bank-owned life insurance (BOLI). BOLI involves the purchasing of life insurance by the Corporation for certain employees. The Corporation is the owner and beneficiary of the policies, however certain policies include split-dollar endorsements. Under these endorsements, beneficiaries of the insured individuals are entitled to a portion of the proceeds from the policy upon death of the insured. The life insurance investment is carried at the net cash surrender value of the underlying policies. Changes in the net cash surrender value of these policies are reflected in noninterest income. Proceeds from and purchases of bank owned life insurance are reflected in the consolidated statements of cash flows under investing activities. The Corporation recognizes a liability for the future death benefit for certain endorsement split-dollar life insurance arrangements that provide an employee with a death benefit in a postretirement/termination period.
Other Real Estate Owned	Other Real Estate Owned Other real estate owned (OREO) represents properties acquired through customers’ loan defaults and is included in other assets. The real estate is originally stated at an amount equal to the fair value of the property, less estimated costs to sell. The fair value less cost to sell becomes the "original cost" of the OREO asset. The amount, if any, by which the carrying amount of the loan plus recorded accrued interest (the recorded loan amount) exceeds the fair value less cost to sell of the OREO, the loss is charged against the reserve for loan and lease losses at the time of foreclosure or repossession. If the fair value less cost to sell of the OREO asset when taken into possession is greater than the recorded loan amount, the excess is first applied as a recovery against any prior charge-offs of the loan and any remaining gain is recorded as other noninterest income. Subsequently, OREO will be reported at the lower of the original cost and the current the fair value less cost to sell. Subsequent write-downs and any gain or loss upon the sale of OREO is recorded in other noninterest income. Capital improvement expenses associated with the construction or repair of the property are capitalized as part of the cost of the OREO asset; however, the capitalized expenses may not increase the OREO asset's recorded value to an amount greater than the asset's fair value after improvements and less cost to sell. Overages and subsequent carrying costs are expensed as incurred.
Derivative Financial Instruments	Derivative Financial Instruments The Corporation recognizes all derivative financial instruments on its balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through income. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative are either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings, or recognized in other comprehensive income until the underlying forecasted transaction is recognized in earnings. The ineffective portion of a derivative's change in fair value is recognized in earnings immediately. To determine fair value, the Corporation uses third party pricing models that incorporate assumptions about market conditions and risks that are current at the reporting date. The Corporation may use interest-rate swap agreements to modify interest rate characteristics from variable to fixed or fixed to variable in order to reduce the impact of interest rate changes on future net interest income. The Corporation accounts for its interest-rate swap contracts in cash flow hedging relationships by establishing and documenting the effectiveness of the instrument in offsetting the change in cash flows of assets or liabilities that are being hedged. To determine effectiveness, the Corporation performs an analysis to identify if changes in fair value of the derivative correlate to the equivalent changes in the forecasted interest receipts related to a specified hedged item. Recorded amounts related to interest-rate swaps are included in other assets or liabilities. Changes in the fair value of derivative instruments designated as hedges of future cash flows are recognized in accumulated other comprehensive income until the underlying forecasted transactions occur, at which time the deferred gains and losses are recognized in earnings. The change in fair value of the ineffective part of the instrument would be charged to earnings, potentially causing material fluctuations in reported earnings in the period of the change relative to comparable periods. In a fair value hedge, the fair values of the interest rate swap agreements and changes in the fair values of the hedged items are recorded in the Corporation’s consolidated balance sheet with the corresponding gain or loss being recognized in the consolidated statement of income. The difference between changes in the fair values of interest rate swap agreements and the hedged items represents hedge ineffectiveness and is recorded in net interest income in the consolidated statement of income. The Corporation performs an assessment, both at the inception of the hedge and quarterly thereafter, to determine whether these derivatives are highly effective in offsetting changes in the value of the hedged items. The Corporation has agreements with third-party financial institutions whereby the third-party financial institution enters into interest rate derivative contracts and foreign currency swap contracts with loan customers referred to them by the Corporation. The Corporation records the fair value of credit derivatives in other liabilities on the consolidated balance sheets. The Corporation recognizes changes in the fair value of credit derivatives, net of any fees received, in other noninterest income in the consolidated statements of income. In connection with its mortgage banking activities, the Corporation enters into commitments to originate certain fixed-rate residential mortgage loans for customers, also referred to as interest rate locks. In addition, the Corporation enters into forward commitments for the future sale of mortgage loans to third-party investors to hedge the effect of changes in interest rates on the value of the interest rate locks. Forward loan sale commitments may also be in the form of commitments to sell individual mortgage loans at a fixed price at a future date. Both the interest rate locks and the forward loan sale commitments are accounted for as derivatives and carried at fair value, determined as the amount that would be necessary to settle each derivative financial instrument at the balance sheet date. Gross derivative assets and liabilities are recorded within other assets and other liabilities on the consolidated balance sheets, with changes in fair value during the period recorded within the net gain on mortgage banking activities on the consolidated statements of income.
Income Taxes	Income Taxes There are two components of income tax expense: current and deferred. Current income tax expense approximates cash to be paid or refunded for taxes for the applicable period. Deferred income taxes are provided for temporary differences between amounts reported for financial statement and tax purposes. Deferred income taxes are computed using the asset and liability method, such that deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between financial reporting amounts and the tax basis of existing assets and liabilities based on currently enacted tax laws and tax rates in effect for the periods in which the differences are expected to reverse. Deferred tax assets are subject to management’s judgment based upon available evidence that future realizations are “more likely than not.” If management determines that the Corporation is not more likely than not, to realize some or all of the net deferred tax asset in the future, a charge to income tax expense may be required to reduce the value of the net deferred tax asset to the expected realizable value. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Penalties are recorded in noninterest expense in the year they are assessed and paid and are treated as a non-deductible expense for tax purposes. Interest is recorded in noninterest expense in the year it is assessed and paid and is treated as a deductible expense for tax purposes.
Retirement Plans and Other Postretirement Benefits	Retirement Plans and Other Postretirement Benefits Substantially all employees who were hired before December 8, 2009 are covered by a noncontributory retirement plan. Effective December 31, 2009, the benefits previously accrued under the noncontributory retirement plan were frozen and the plan was amended and converted to a cash balance plan, with participants not losing any pension benefits already earned in the plan. Prior to the cash balance plan conversion effective December 31, 2009, the plan provided benefits based on a formula of each participant’s final average pay. Future benefits under the cash balance plan accrue by crediting participants annually with an amount equal to a percentage of earnings in that year based on years of credited service as defined in the plan. Employees hired on or after December 8, 2009 are not eligible to participate in the noncontributory retirement plan. The Corporation also provides supplemental executive retirement benefits to certain former executives, a portion of which is in excess of limits imposed on qualified plans by federal tax law; these plans are non-qualified benefit plans. These non-qualified benefit plans are not offered to new participants; all current participants are now retired. The Corporation provides certain postretirement healthcare and life insurance benefits for retired employees. The Corporation’s measurement date for plan assets and obligation is fiscal year-end. The Corporation recognizes on its consolidated balance sheet the funded status of its defined pension plans and changes in the funded status of the plan in the year in which the changes occur. An under-funded position would create a liability and an over-funded position would create an asset, with a correlating deferred tax asset or liability. The net impact would be an adjustment to equity as accumulated other comprehensive income (loss). The Corporation recognizes as a component of other comprehensive income (loss), net of tax, the actuarial gains and losses and the prior service costs and credits that arise during the period. The Corporation sponsors a 401(k) deferred salary savings plan, which is a qualified defined contribution plan, and which covers all employees of the Corporation and its subsidiaries, and provides that the Corporation make matching contributions as defined by the plan. The Corporation sponsors a Supplemental Non-Qualified Pension Plan (SNQPP) which was established in 1981 prior to the existence of a 401(k) deferred salary savings, employee stock purchase and long-term incentive plans and therefore is not offered to new participants; all current participants are now retired. These non-qualified plans are accounted for under guidance for deferred compensation arrangements.
Stock-Based Compensation	Stock-Based Compensation The fair value of share based awards is recognized as compensation expense over the vesting period based on the grant-date fair value of the awards. The Corporation uses the Black-Scholes Model to estimate the fair value of each option on the date of grant. The Black-Scholes Model estimates the fair value of employee stock options using a pricing model which takes into consideration the exercise price of the option, the expected life of the option, the current market price and its expected volatility, the expected dividends on the stock and the current risk-free interest rate for the expected life of the option. The Corporation grants stock options to employees with an exercise price equal to the fair value of the shares at the date of grant. The Corporation grants both fixed and variable (performance-based) restricted stock. The performance-based restricted stock awards vest based upon the Corporation’s performance against selected peers with respect to certain financial measures over a three -year period. The fair value of fixed restricted stock is equivalent to the fair value on the date of grant and is amortized over the vesting period. The fair value of the performance-based restricted stock is equivalent to the fair value on the date of grant and is amortized over the vesting period adjusted for a probability factor of achieving the performance goals.
Dividend Reinvestment and Employee Stock Purchase Plans	Dividend Reinvestment and Employee Stock Purchase Plans The Univest Dividend Reinvestment Plan allows for the issuance of 1,968,750 shares of common stock. During 2016 and 2015 , 86,350 and 87,946 shares, respectively, were issued under the dividend reinvestment plan, with 377,885 shares available for future purchase at December 31, 2016 . The 1996 Employee Stock Purchase Plan allows for the issuance of 984,375 shares of common stock. Employees may elect to make contributions to the plan in an aggregate amount not less than 2% or more than 10% of such employee’s total compensation. These contributions are then used to purchase stock during an offering period determined by the Corporation’s Employee Stock Purchase Plan Committee. The purchase price of the stock is 90% of the closing sale price on the last trading day of each quarter. Compensation expense is recognized as the discount is greater than 5% of the fair value. During 2016 and 2015 , 28,919 and 26,440 shares, respectively, were issued under the employee stock purchase plan, with 677,265 shares available for future purchase at December 31, 2016 .
Marketing and Advertising Costs	Marketing and Advertising Costs The Corporation’s accounting policy is to expense marketing and advertising costs as incurred, when the advertisement first takes place, or over the expected useful life of the related asset, as would be the case with billboards.
Statement of Cash Flows	Statement of Cash Flows The Corporation has defined those items included in the caption “Cash and due from banks” as cash and cash equivalents.
Trust Assets	Trust Assets Assets held by the Corporation in a fiduciary or agency capacity for its customers are not included in the consolidated financial statements since such items are not assets of the Corporation.
Earnings per Share	Earnings per Share The Corporation uses the two-class method to calculate earnings per share as the unvested restricted stock issued under the Corporation's equity incentive plans are participating shares with nonforfeitable rights to dividends. Under the two-class method, earnings per common share are computed by dividing the sum of distributed earnings to common shareholders and undistributed earnings allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities based on the number of weighted average shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if options on common shares had been exercised, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Corporation relate solely to outstanding stock options, and are determined using the treasury stock method. The effects of options to issue common stock are excluded from the computation of diluted earnings per share in periods in which the effect would be antidilutive.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2016, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU) to require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years for public business entities, or January 1, 2018 for the Corporation. The amendments in this ASU should be applied using a retrospective transition method to each period presented. The Corporation does not anticipate the adoption of this ASU will have a material impact on the statement of cash flows. In August 2016, the FASB issued an ASU to provide guidance for eight cash flow classification issues for certain cash receipts and cash payments with the objective of reducing diversity in practice. The issues identified within the ASU include: debt prepayments or extinguishment costs; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. The ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those years for public business entities that are SEC filers, or January 1, 2018 for the Corporation. The Corporation does not anticipate the adoption of this ASU will have a material impact on the financial statements. In June 2016, the FASB issued an ASU to require businesses and other organizations to measure the current expected credit losses (CECL) on financial assets, such as loans, net investments in leases, certain debt securities, bond insurance and other receivables. The amendments affect entities holding financial assets and net investments in leases that are not accounted for at fair value through net income. Current GAAP requires an incurred loss methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. The amendments in this ASU replace the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonableness and supportable information to inform credit loss estimates. An entity should apply the amendments through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (modified-retrospective approach). Acquired credit impaired loans for which the guidance in Accounting Standards Codification (ASC) Topic 310-30 has been previously applied should prospectively apply the guidance in this ASU. A prospective transition approach is required for debt securities for which an other-than-temporary impairment has been recognized before the effective date. The ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those years for public business entities that are SEC filers, or January 1, 2020 for the Corporation. The Corporation is in the process of evaluating the impact of the adoption of this guidance on the Corporation's financial statements; however, it is anticipated that the allowance will increase upon adoption of CECL and that the increased allowance level will decrease regulatory capital and ratios. In March 2016, the FASB issued an ASU to simplify and improve employee share-based payment accounting. Under the new guidance, all excess tax benefits and tax deficiencies are recognized as an income tax benefit or expense in the income statement. The additional paid-in capital pool is eliminated. Excess tax benefits and deficiencies are recognized in the period they are deducted on the income tax return. Excess tax benefits are recorded along with other income tax cash flows as an operating activity in the statement of cash flows. The recognition of excess tax benefits and deficiencies and changes to diluted earnings per share are applied prospectively when this ASU is adopted. For tax benefits that were not previously recognized because the related tax deduction had not reduced taxes payable, entities record a cumulative-effect adjustment in retained earnings as of the beginning of the year of adoption. The Corporation does not record deferred tax benefits on incentive stock options when expense is accrued, therefore, the Corporation does not have a cumulative-effect adjustment upon adoption of this ASU. Changes to the treatment of forfeitures will not impact the Corporation as the historical assumption for forfeitures was immaterial and not taken into account during valuations; the Corporation has recorded forfeitures as they occurred which is consistent with the new guidance. The ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within those years for public business entities, or January 1, 2017 for the Corporation. Early adoption is permitted in any interim or annual period provided that the entire ASU is adopted. The Corporation adopted this ASU effective January 1, 2016 on a prospective basis. Prior periods have not been adjusted. All excess tax benefits and tax deficiencies for 2016 were recognized as a net income tax benefit in the statement of income. The additional paid-in capital pool was eliminated. The net impact of this adoption was $301 thousand in net income tax benefits recorded in the statement of income for the year ended December 31, 2016. The adoption of this ASU did not have a material impact on the Corporation's financial statements. In March 2016, the FASB issued an ASU to amend the guidance for hedge accounting to clarify that a change in the counterparty to a derivative instrument that has been designated as a hedging instrument does not require de-designation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The amendments in this ASU are effective for financial statements of public businesses issued for fiscal years and interim periods within those years beginning after December 15, 2016, or January 1, 2017 for the Corporation. The adoption of this ASU did not have any impact on the Corporation's financial statements. In February 2016, the FASB issued an ASU to revise the accounting related to lessee accounting. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases. Disclosures will be required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. The ASU is effective for the first interim period within annual periods beginning after December 15, 2018, or January 1, 2019, with early adoption permitted. The Corporation is in the process of evaluating the impact of the adoption of this guidance on the Corporation's financial statements; however, the adoption of this ASU will impact the balance sheet for the recording of assets and liabilities for operating leases; any initial or continued impact of the recording of assets will have an impact on risk-based capital ratios under current regulatory guidance and possibly equity ratios. In January 2016, the FASB issued an ASU to address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The ASU will require equity investments to be measured at fair value with changes in fair value recognized in net income. When fair value is not readily determinable, an entity may elect to measure the equity investment at cost, minus impairment, plus or minus any change in the investment’s observable price. The ASU will simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. A valuation allowance on a deferred tax asset related to available-for-sale securities will need to be included. For financial liabilities that are measured at fair value, the ASU requires an entity to present separately, in other comprehensive income, any change in fair value resulting from a change in instrument-specific credit risk. An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. The amendments in this ASU are effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2017 or January 1, 2018 for the Corporation. The Corporation is in the process of evaluating the impact of the adoption of this guidance on the Corporation's financial statements. In September 2015, the FASB issued an ASU simplifying the accounting for measurement-period adjustments related to business combinations. The ASU eliminates the requirement to retrospectively adjust the financial statements for measurement-period adjustments that occur in periods after a business combination is consummated. Under this ASU, measurement-period adjustments are calculated as if they were known at the acquisition date, but are recognized in the reporting period in which they are determined. The ASU requires additional disclosures about the impact on current period income statement line items of adjustments that would have been recognized in prior periods if prior period information had been revised. The amendments in this ASU were effective for financial statements of public businesses issued for fiscal years and interim periods within those years beginning after December 15, 2015, or January 1, 2016 for the Corporation. The adoption of this guidance did not impact the Corporation's financial statements. In April 2015, the FASB issued an ASU simplifying the presentation of debt issuance costs. The ASU requires that debt issuance costs related to a recognized debt liability shall be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The costs will continue to be amortized to interest expense using the effective interest method. The ASU was effective for financial statements of public businesses issued for fiscal years beginning after December 15, 2015, or January 1, 2016 for the Corporation. The adoption of this ASU did not impact the Corporation's balance sheet presentation as the Corporation followed this presentation consistent with the guidance in FASB Concepts Statement No. 6. In May 2014, the FASB issued an ASU regarding revenue from contracts with customers which clarifies the principles for recognizing revenue and develops a common standard for U.S. GAAP and International Financial Reporting Standards. The ASU establishes a core principle that would require an entity to identify the contract(s) with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when (or as) the entity satisfies a performance obligation. The ASU provides for improved disclosure requirements that require entities to disclose sufficient information that enables users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In March 2016, the FASB issued an ASU clarifying the implementation guidance on the principal-versus-agent considerations in the revenue recognition standard by instructing the participants in the sale to determine whether they control the good or service and are entitled to the gross amount of the transaction or are acting as an agent and should collect only a fee or commission for arranging the sale. In April 2016, the FASB issued an ASU clarifying the identification of performance obligations and licensing. In May 2016, the FASB issued an ASU providing some limited improvements and practical expedients. The original effective date of the guidance relating to revenue from contracts with customers was deferred in August 2015 by one year. This guidance is now effective for fiscal years and interim periods within those years beginning after December 15, 2017, or January 1, 2018 for the Corporation. The Corporation is in the process of evaluating the impact of the adoption of this guidance on the Corporation's financial statements; however, it is anticipated the impact will be only related to timing.

The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the par value of the investment. It is more likely than not that the Corporation will not be required to sell the investments before a recovery of carrying value.

Banking and Thrift [Abstract]
Schedule of Compliance with Regulatory Capital Requirements under Banking Regulations	Quantitative measures established by regulation to ensure capital adequacy require the Corporation and the Bank to maintain minimum amounts and ratios (set forth in the following table) of Total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined), or leverage ratio. In July 2013, the federal bank regulatory agencies adopted final rules revising the agencies’ capital adequacy guidelines and prompt corrective action rules, designed to enhance such requirements and implement the revised standards of the Basel Committee on Banking Supervision, commonly referred to as Basel III. The new minimum capital requirements were effective on January 1, 2015. Under the new rules, in order to avoid limitations on capital distributions (including dividend payments and certain discretionary bonus payments to executive officers), a banking organization must hold a capital conservation buffer comprised of common equity Tier 1 capital above its minimum risk-based capital requirements in an amount greater than 2.5% of total risk-weighted assets. The capital conservation buffer requirements phase in over a four -year period beginning January 1, 2016. The Corporation adopted the new Basel III regulatory capital rules during the first quarter of 2015 under the transition rules, primarily relating to regulatory deductions and adjustments impacting common equity tier 1 capital and tier 1 capital, to be phased in over a three -year period beginning January 1, 2015 . Under Basel III rules, the decision was made to opt-out of including accumulated other comprehensive income in regulatory capital. During 2016, the Corporation and the Bank were required to hold a capital conservation buffer greater than 0.625% above its minimum risk-based capital requirements in order to avoid limitations on capital distributions. During 2017, the Corporation and the Bank must hold a capital conservation buffer greater than 1.25% above its minimum risk-based capital requirements in order to avoid limitations on capital distributions. The Corporation's and Bank's actual and required capital ratios as of December 31, 2016 and December 31, 2015 under BASEL III regulatory capital rules were as follows.
