Summary of Significant Accounting Policies	Sep. 30, 2017
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The accompanying unaudited consolidated financial statements include the accounts of Univest Corporation of Pennsylvania (the Corporation or Univest) and its wholly owned subsidiaries. The Corporation’s direct subsidiary is Univest Bank and Trust Co. (the Bank). All significant intercompany balances and transactions have been eliminated in consolidation. The unaudited interim consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations for interim financial information. The accompanying unaudited consolidated financial statements reflect all adjustments which are of a normal recurring nature and are, in the opinion of management, necessary for a fair presentation of the financial statements for the interim periods presented. Certain prior period amounts have been reclassified to conform to the current-year presentation. Operating results for the three and nine -month periods ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ended December 31, 2017 or for any other period. It is suggested that these unaudited consolidated financial statements be read in conjunction with the audited financial statements and the notes thereto included in the registrant’s Annual Report on Form 10-K for the year ended December 31, 2016 , which was filed with the SEC on March 3, 2017 . Use of Estimates The preparation of the unaudited consolidated financial statements in conformity with 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, purchase accounting, valuation of goodwill and other intangible assets, servicing rights, deferred tax assets and liabilities, benefit plans and stock-based compensation. Recent Accounting Pronouncements In August 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. " The amendments in this update expand and refine hedge accounting for both non-financial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. Additional hedging strategies permitted for hedge accounting include: hedges of contractually-specified price components of commodity purchases or sales, hedges of the benchmark rate component of the contractual coupon cash flows of fixed-rate assets or liabilities, hedges of the portion of a closed portfolio of prepayable assets not expected to prepay, and partial-term hedges of fixed-rate assets or liabilities. The ASU amends the presentation and disclosure requirements and changes how entities assess effectiveness. The ASU eliminates the requirement to separately measure and report hedge ineffectiveness and requires all items that affect earnings be presented in the same income statement line as the hedged items. After initial qualification, the new guidance permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test, such as a regression analysis, if the entity can reasonably support an expectation of high effectiveness throughout the term of the hedge. An initial quantitative test to establish that the hedge relationship is highly effective is still required. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for public business entities, or January 1, 2019 for the Corporation. Early adoption is permitted, including an interim period. The amended presentation and disclosure guidance is required only prospectively. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In May 2017, the FASB issued ASU No. 2017-09, “Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting." This ASU provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. The ASU does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, or January 1, 2018 for the Corporation. Early adoption is permitted, including an interim period. The amendments in this ASU should be applied prospectively to an award modified on or after the adoption. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In March 2017, the FASB issued ASU No. 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” This ASU shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, or January 1, 2019 for the Corporation. Early adoption is permitted, including an interim period. This ASU is to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption.The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In March 2017, the FASB issued ASU No. 2017-07, "Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The amendments in this ASU require that an employer that sponsors defined benefit pension plans and other postretirement plans present the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. Other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendments also allow only the service cost component to be eligible for capitalization, when applicable. This ASU is effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those annual periods, or January 1, 2018 for the Corporation. This ASU should be applied retrospectively for the presentation requirements and prospectively for the capitalization of the service cost component requirements. The amendments allow a practical expedient that permits an employer to use the amounts disclosed in its pension and other postretirement benefit plan note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. Disclosure that the practical expedient was used is required. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In January 2017, the FASB issued ASU No. 2017-04, "Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This ASU eliminates Step 2 of the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the new guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are SEC filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, or for the Corporation's goodwill impairment test in 2020. Early adoption is permitted for goodwill impairment tests with measurement dates after January 1, 2017. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business." The amendments in this ASU clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the current implementation guidance in Topic 805, there are three elements of a business – inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a “set”) that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this ASU provide a screen to determine when a set is not a business. If the screen is not met, the amendments (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output, and (2) remove the evaluation of whether a market participant could replace missing elements. The ASU provides a framework to assist entities in evaluating whether both an input and a substantive process are present. The amendments in this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, or January 1, 2018 for the Corporation. The amendments in this ASU should be applied prospectively on or after the effective date. The Corporation does not anticipate the adoption of this ASU will have a material impact on the Corporation's financial statements. In June 2016, the FASB issued ASU No. 2016-13, “ Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This ASU requires 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 shareholders' equity and regulatory capital and ratios. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" 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 a negative impact on all Corporation and Bank capital ratios under current regulatory guidance and possibly equity ratios. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." This ASU addresses 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. At September 30, 2017 , the Corporation's equity portfolio had a carrying value of $1.0 million which included an unrealized net gain of $590 thousand . This unrealized net gain, net of income taxes, amounted to $384 thousand and was recorded in accumulated other comprehensive income. Upon implementation using the prospective approach, the balance in accumulated other comprehensive income will be reclassed to retained earnings. The carrying value of the equity securities, upon implementation, will not change; however, any future increases or decreases in fair value will be recorded as an increase or decrease to the carrying value and recognized in non-interest income. In May 2014, the FASB issued ASU No. 2014-09, " Revenue from Contracts with Customers (Topic 606)” and subsequent related updates. This ASU 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 requires 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. The Corporation will adopt the guidance effective January 1, 2018 and expects to use the modified retrospective method with a cumulative-effect adjustment to opening retained earnings, if such adjustment is deemed significant. The Corporation’s revenue is the sum of net interest income and noninterest income. The scope of the guidance excludes nearly all net interest income as well as many other revenues for financial assets and liabilities including loans, leases, securities, and derivatives. The Corporation has completed the initial scoping review and determined that approximately 82% of non-interest income revenue streams are within the scope of the new standard. Non-interest income streams that are out of scope of the new standard include BOLI, sales of investment securities, mortgage banking activities, certain items within other service fee income such as mortgage servicing income, and certain items within other income. Management is currently reviewing contracts related to trust fee income, service charges on deposits, investment advisory commissions and fee income, insurance commission and fee income and certain items within other service fee income and other income. While the Corporation has not identified material changes to the timing or amount of revenue recognition, the review is ongoing. The Corporation is evaluating changes that may be necessary to applicable disclosures of disaggregation of total revenue, information about performance obligations, information about key judgments and estimates and policy decisions regarding revenue recognition.

Earnings Per Share, Basic and Diluted [Abstract]
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. The table also notes anti-dilutive options which are those options with weighted average exercise prices in excess of the weighted average market value for the periods presented. The following table sets forth the computation of basic and diluted earnings per share: Three Months Ended Nine Months Ended (Dollars and shares in thousands, except per share data) 2017 2016 2017 2016 Numerator: Net income $ 11,196 $ 58 $ 33,830 $ 12,587 Net income allocated to unvested restricted stock (96 ) — (330 ) (102 ) Net income allocated to common shares $ 11,100 $ 58 $ 33,500 $ 12,485 Denominator: Denominator for basic earnings per share— weighted-average shares outstanding 26,437 26,274 26,388 21,720 Effect of dilutive securities—employee stock options 105 67 102 41 Denominator for diluted earnings per share— adjusted weighted-average shares outstanding 26,542 26,341 26,490 21,761 Basic earnings per share $ 0.42 $ — $ 1.27 $ 0.58 Diluted earnings per share $ 0.42 $ — $ 1.27 $ 0.57 Average anti-dilutive options excluded from computation of diluted earnings per share 185 201 166 550

Unrealized losses in investment securities at September 30, 2017 and December 31, 2016 do not represent other-than-temporary impairments in management's judgment. Securities with a carrying value of $335.5 million and $356.7 million at September 30, 2017 and December 31, 2016 , respectively, were pledged to secure public deposits and other contractual obligations. In addition, securities of $1.9 million and $1.4 million were pledged to secure credit derivatives and interest rate swaps at September 30, 2017 and December 31, 2016 , respectively. See Note 10, "Derivative Instruments and Hedging Activities" for additional information. The following table presents information related to sales of securities available-for-sale during the nine months ended September 30, 2017 and 2016 : Nine Months Ended September 30, (Dollars in thousands) 2017 2016 Securities available-for-sale: Proceeds from sales $ 3,538 $ 75,265 Gross realized gains on sales 43 568 Gross realized losses on sales — 81 Tax expense related to net realized gains on sales 15 170 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. 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 did not recognize any other-than-temporary impairment charges on debt securities for the nine months ended September 30, 2017 and 2016 . At September 30, 2017 and December 31, 2016 , 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 September 30, 2017 and December 31, 2016 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 investment before a recovery of carrying value.

The provision for loan losses related to this program was $1.9 million during the quarter ended September 30, 2017 as the Corporation had an allowance for loan and lease losses reserve of $886 thousand as of June 30, 2017. These leases are personally guaranteed by 29 high net worth individuals. During the first quarter of 2017, the lessees stopped making payments due to disputes with the vendor, and Univest Capital, Inc., a subsidiary of the Corporation, filed legal complaints to pursue collection of all amounts owed. A complaint was subsequently filed against Univest Capital Inc. and certain other defendants on March 28, 2017 by one of the lessees in federal court in Texas seeking, among other things, class action certification and a declaration that the contracts and related guarantees are null and void. On September 25, 2017 , Univest Capital, Inc. entered into a Release and Settlement Agreement whereby Univest Capital, Inc. will receive $1.0 million based upon court approval of the Agreement and is eligible to receive up to an additional $1.3 million . Payment of the $1.3 million is subject to the individual guarantor's election of whether or not they will be subject to the Release and Settlement Agreement. It is expected this election process will be completed by March 31, 2018 . If a guarantor elects to be subject to the Release and Settlement Agreement, Univest Capital, Inc. will receive a payment of $43 thousand per guarantor. If a guarantor elects not to be subject to the Release and Settlement Agreement, Univest Capital, Inc. has the right to pursue collection of the full amount owed, which ranges from $108 thousand to $228 thousand per guarantor, via the normal collection process. As of September 30, 2017, Univest Capital, Inc. has a receivable totaling $2.3 million related to this matter, of which $1.3 million is recorded as a nonaccruing lease receivable and $1.0 million is included in other assets. The $1.0 million payment under the Release and Settlement Agreement, which is subject to court approval, is currently in escrow and is expected to be received during the fourth quarter of 2017.

After the acquisition measurement period, the present value of any decreases in expected cash flows of acquired credit impaired loans will generally result in an impairment charge recorded as a provision for loan loss, resulting in an increase to the allowance.

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 include other accruing impaired loans of $4.8 million and $23.3 million at September 30, 2017 and December 31, 2016 , respectively. Specific reserves on other accruing impaired loans were $73 thousand and $84 thousand at September 30, 2017 and December 31, 2016 , respectively. The following presents by class of loans, the average recorded investment in impaired loans and an analysis of interest on impaired loans.

Derivative Instruments and Hedging Activities	Sep. 30, 2017
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. In 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 of 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 September 30, 2017 , approximately $108 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 September 30, 2017 . At September 30, 2017 , the notional amount of the interest rate swap was $18.0 million , with a negative fair value of $174 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 $549 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 September 30, 2017 , the Corporation has fourteen variable-rate to fixed-rate interest rate swap transactions between the third-party financial institution and customers with a current notional amount of $66.1 million , and remaining maturities ranging from one to 10 years. At September 30, 2017 , the fair value of the swaps to the customers was a liability of $132 thousand and all swaps were in paying positions to the third-party financial institution. At September 30, 2017 , 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 September 30, 2017 and December 31, 2016 . The Corporation pledges cash or securities to cover the negative fair value of derivative instruments. Cash collateral associated with derivative instruments are not added to or netted against the fair value amounts.

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. Level 2 of the valuation hierarchy includes securities issued by U.S. Government sponsored enterprises, mortgage-backed securities, collateralized mortgage obligations, corporate and municipal bonds and certain equity securities. 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. 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 not have 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 bonds owned by the Corporation are classified as Level 3 as they are not traded in active markets. The fair value of each bond 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 September 30, 2017 . 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 $75 thousand at September 30, 2017 . 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 conclusion for the earn-out period ending June 30, 2017 resulted in a reversal of a prior noninterest expense accrual of $301 thousand primarily during the second quarter of 2017. The following table presents the assets and liabilities measured at fair value on a recurring basis at September 30, 2017 and December 31, 2016 , classified using the fair value hierarchy: At September 30, 2017 (Dollars in thousands) Level 1 Level 2 Level 3 Assets/ Assets: Available-for-sale securities: U.S. government corporations and agencies $ — $ 17,090 $ — $ 17,090 State and political subdivisions — 80,725 — 80,725 Residential mortgage-backed securities — 174,570 — 174,570 Collateralized mortgage obligations — 3,842 — 3,842 Corporate bonds — 85,884 28,545 114,429 Money market mutual funds 6,624 — — 6,624 Equity securities 1,000 — — 1,000 Total available-for-sale securities 7,624 362,111 28,545 398,280 Loans* — — 2,014 2,014 Interest rate locks with customers* — 1,234 — 1,234 Total assets $ 7,624 $ 363,345 $ 30,559 $ 401,528 Liabilities: Contingent consideration liability $ — $ — $ 359 $ 359 Interest rate swaps* — 249 — 249 Credit derivatives* — — 132 132 Forward loan sale commitments* — 1 — 1 Total liabilities $ — $ 250 $ 491 $ 741 At December 31, 2016 (Dollars in thousands) Level 1 Level 2 Level 3 Assets/ Assets: Available-for-sale securities: U.S. government corporations and agencies $ — $ 32,266 $ — $ 32,266 State and political subdivisions — 88,350 — 88,350 Residential mortgage-backed securities — 198,570 — 198,570 Collateralized mortgage obligations — 4,554 — 4,554 Corporate bonds — 79,420 28,778 108,198 Money market mutual funds 10,784 — — 10,784 Equity securities 915 — — 915 Total available-for-sale securities 11,699 403,160 28,778 443,637 Loans* — — 2,138 2,138 Interest rate locks with customers* — 801 — 801 Forward loan sale commitments* — 257 — 257 Total assets $ 11,699 $ 404,218 $ 30,916 $ 446,833 Liabilities: Contingent consideration liability $ — $ — $ 5,999 $ 5,999 Interest rate swaps* — 319 — 319 Credit derivatives* — — 9 9 Total liabilities $ — $ 319 $ 6,008 $ 6,327 * Such financial instruments are recorded at fair value as further described in Note 10 - Derivative Instruments.

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 September 30, 2017 and December 31, 2016 . 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. Impaired loans and leases held for investment: For impaired loans and leases, the Corporation uses a variety of techniques to measure fair value, such as using the current appraised value of the collateral, agreements of sale, discounting the contractual cash flows, and analyzing market data that the Corporation may adjust due to specific characteristics of the loan/lease or collateral. At September 30, 2017 , impaired loans held for investment had a carrying amount of $30.6 million with a valuation allowance of $88 thousand . At December 31, 2016 , impaired loans held for investment had a carrying amount of $43.9 million with a valuation allowance of $235 thousand . The Corporation had impaired leases of $1.3 million with no reserve at September 30, 2017 . The Corporation had no impaired leases at December 31, 2016 . 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. The Corporation also records servicing rights on SBA loans. At September 30, 2017 and December 31, 2016 , servicing rights had a carrying amount of $6.6 million 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. During the nine months ended September 30, 2017 , there were no triggering events that required valuation of goodwill and other identifiable intangible assets. 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. During 2017, two properties had write-downs totaling $199 thousand and seven properties were sold at a net gain of $383 thousand which were both included in other noninterest income in the statement of income. New appraisals are generally obtained on an annual basis if an agreement of sale does not exist. 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 short-term borrowings 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 the 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.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting At September 30, 2017 , 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, consumer and mortgage banking as well as lease financing. 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. 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. 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. 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.

Commitments and Contingencies Disclosure [Abstract]
Contingencies Disclosure	Contingencies The Corporation is periodically subject to various pending and threatened legal actions, which involve claims for monetary relief. Based upon information presently available to the Corporation, it is the Corporation's opinion that any legal and financial responsibility arising from such claims will not have a material adverse effect on the Corporation's results of operations, financial position or cash flows. As discussed in Note 4, during the first quarter of 2017, certain lessees stopped making payments and Univest Capital, Inc., a subsidiary of the Corporation, filed legal complaints to pursue collection of all amounts owed. A complaint was subsequently filed against Univest Capital, Inc. and certain other defendants on March 28, 2017 by one of the lessees in federal court in Texas seeking, among other things, class action certification and a declaration that the contracts and related guarantees are null and void. On September 25, 2017 , Univest Capital, Inc. entered into a Release and Settlement Agreement whereby Univest Capital, Inc. will receive $1.0 million based upon court approval of the Agreement and is eligible to receive up to an additional $1.3 million . Payment of the $1.3 million is subject to the individual guarantor's election of whether or not they will be subject to the Release and Settlement Agreement. It is expected this election process will be completed by March 31, 2018 . If a guarantor elects to be subject to the Release and Settlement Agreement, Univest Capital, Inc. will receive a payment of $43 thousand per guarantor. If a guarantor elects not to be subject to the Release and Settlement Agreement, Univest Capital, Inc. has the right to pursue collection of the full amount owed, which ranges from $108 thousand to $228 thousand per guarantor, via the normal collection process. As of September 30, 2017, Univest Capital, Inc. has a receivable totaling $2.3 million related to this matter, of which $1.3 million is recorded as a nonaccruing lease receivable and $1.0 million is included in other assets. The $1.0 million payment under the Release and Settlement Agreement, which is subject to court approval, is currently in escrow and is expected to be received during the fourth quarter of 2017.

Summary of Significant Accounting Policies (Policies)	Sep. 30, 2017
Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The accompanying unaudited consolidated financial statements include the accounts of Univest Corporation of Pennsylvania (the Corporation or Univest) and its wholly owned subsidiaries. The Corporation’s direct subsidiary is Univest Bank and Trust Co. (the Bank). All significant intercompany balances and transactions have been eliminated in consolidation. The unaudited interim consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations for interim financial information. The accompanying unaudited consolidated financial statements reflect all adjustments which are of a normal recurring nature and are, in the opinion of management, necessary for a fair presentation of the financial statements for the interim periods presented. Certain prior period amounts have been reclassified to conform to the current-year presentation. Operating results for the three and nine -month periods ended September 30, 2017 are not necessarily indicative of the results that may be expected for the year ended December 31, 2017 or for any other period. It is suggested that these unaudited consolidated financial statements be read in conjunction with the audited financial statements and the notes thereto included in the registrant’s Annual Report on Form 10-K for the year ended December 31, 2016 , which was filed with the SEC on March 3, 2017 .
Use of Estimates	Use of Estimates The preparation of the unaudited consolidated financial statements in conformity with 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, purchase accounting, valuation of goodwill and other intangible assets, servicing rights, deferred tax assets and liabilities, benefit plans and stock-based compensation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. " The amendments in this update expand and refine hedge accounting for both non-financial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. Additional hedging strategies permitted for hedge accounting include: hedges of contractually-specified price components of commodity purchases or sales, hedges of the benchmark rate component of the contractual coupon cash flows of fixed-rate assets or liabilities, hedges of the portion of a closed portfolio of prepayable assets not expected to prepay, and partial-term hedges of fixed-rate assets or liabilities. The ASU amends the presentation and disclosure requirements and changes how entities assess effectiveness. The ASU eliminates the requirement to separately measure and report hedge ineffectiveness and requires all items that affect earnings be presented in the same income statement line as the hedged items. After initial qualification, the new guidance permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test, such as a regression analysis, if the entity can reasonably support an expectation of high effectiveness throughout the term of the hedge. An initial quantitative test to establish that the hedge relationship is highly effective is still required. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for public business entities, or January 1, 2019 for the Corporation. Early adoption is permitted, including an interim period. The amended presentation and disclosure guidance is required only prospectively. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In May 2017, the FASB issued ASU No. 2017-09, “Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting." This ASU provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. The ASU does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions, or award classification. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, or January 1, 2018 for the Corporation. Early adoption is permitted, including an interim period. The amendments in this ASU should be applied prospectively to an award modified on or after the adoption. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In March 2017, the FASB issued ASU No. 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.” This ASU shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, or January 1, 2019 for the Corporation. Early adoption is permitted, including an interim period. This ASU is to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption.The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In March 2017, the FASB issued ASU No. 2017-07, "Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The amendments in this ASU require that an employer that sponsors defined benefit pension plans and other postretirement plans present the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. Other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendments also allow only the service cost component to be eligible for capitalization, when applicable. This ASU is effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those annual periods, or January 1, 2018 for the Corporation. This ASU should be applied retrospectively for the presentation requirements and prospectively for the capitalization of the service cost component requirements. The amendments allow a practical expedient that permits an employer to use the amounts disclosed in its pension and other postretirement benefit plan note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. Disclosure that the practical expedient was used is required. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In January 2017, the FASB issued ASU No. 2017-04, "Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This ASU eliminates Step 2 of the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the new guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are SEC filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, or for the Corporation's goodwill impairment test in 2020. Early adoption is permitted for goodwill impairment tests with measurement dates after January 1, 2017. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business." The amendments in this ASU clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the current implementation guidance in Topic 805, there are three elements of a business – inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a “set”) that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this ASU provide a screen to determine when a set is not a business. If the screen is not met, the amendments (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output, and (2) remove the evaluation of whether a market participant could replace missing elements. The ASU provides a framework to assist entities in evaluating whether both an input and a substantive process are present. The amendments in this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, or January 1, 2018 for the Corporation. The amendments in this ASU should be applied prospectively on or after the effective date. The Corporation does not anticipate the adoption of this ASU will have a material impact on the Corporation's financial statements. In June 2016, the FASB issued ASU No. 2016-13, “ Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This ASU requires 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 shareholders' equity and regulatory capital and ratios. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" 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 a negative impact on all Corporation and Bank capital ratios under current regulatory guidance and possibly equity ratios. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." This ASU addresses 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. At September 30, 2017 , the Corporation's equity portfolio had a carrying value of $1.0 million which included an unrealized net gain of $590 thousand . This unrealized net gain, net of income taxes, amounted to $384 thousand and was recorded in accumulated other comprehensive income. Upon implementation using the prospective approach, the balance in accumulated other comprehensive income will be reclassed to retained earnings. The carrying value of the equity securities, upon implementation, will not change; however, any future increases or decreases in fair value will be recorded as an increase or decrease to the carrying value and recognized in non-interest income. In May 2014, the FASB issued ASU No. 2014-09, " Revenue from Contracts with Customers (Topic 606)” and subsequent related updates. This ASU 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 requires 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. The Corporation will adopt the guidance effective January 1, 2018 and expects to use the modified retrospective method with a cumulative-effect adjustment to opening retained earnings, if such adjustment is deemed significant. The Corporation’s revenue is the sum of net interest income and noninterest income. The scope of the guidance excludes nearly all net interest income as well as many other revenues for financial assets and liabilities including loans, leases, securities, and derivatives. The Corporation has completed the initial scoping review and determined that approximately 82% of non-interest income revenue streams are within the scope of the new standard. Non-interest income streams that are out of scope of the new standard include BOLI, sales of investment securities, mortgage banking activities, certain items within other service fee income such as mortgage servicing income, and certain items within other income. Management is currently reviewing contracts related to trust fee income, service charges on deposits, investment advisory commissions and fee income, insurance commission and fee income and certain items within other service fee income and other income. While the Corporation has not identified material changes to the timing or amount of revenue recognition, the review is ongoing. The Corporation is evaluating changes that may be necessary to applicable disclosures of disaggregation of total revenue, information about performance obligations, information about key judgments and estimates and policy decisions regarding revenue recognition.

Amount of Securities in Unrealized Loss Position	The following table shows the fair value of securities that were in an unrealized loss position at September 30, 2017 and December 31, 2016 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 investment before a recovery of carrying value.
