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, 2017 , which was filed with the SEC on March 1, 2018 . 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, reserve for loan and lease losses and purchase accounting. Accounting Pronouncements Adopted in 2018 In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-02, " Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This ASU clarifies the accounting treatment of the reclassification of certain income tax effects within accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act. The Corporation elected to early adopt this guidance effective January 1, 2018 for all stranded tax effects resulting from tax reform and reclassified stranded tax effects, totaling $3.9 million , from accumulated other comprehensive income to retained earnings. The Corporation's policy for releasing income tax effects from accumulated other comprehensive income is to release such effects on an individual basis as each item is liquidated, sold or extinguished. See Note 10, "Accumulated Other Comprehensive (Loss) Income" for additional detail. 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 Corporation adopted this guidance effective January 1, 2018 with retrospective application for prior period presentation. Effective January 1, 2018, components of net benefit income other than the service cost component are presented in the Corporation's statement of income in other noninterest expense rather than in salaries, benefits and commission expense. Prior period components of net benefit income other than the service cost component were reclassed to other noninterest expense in the Corporation's statement of income. 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 requires equity investments to be measured at fair value with changes in fair value recognized in net income. At December 31, 2017 , the Corporation had financial services equity securities with a carrying value of $1.1 million which included an unrealized net gain of $666 thousand . At December 31, 2017 , $433 thousand was recorded in accumulated other comprehensive income which represented the unrealized net gain, net of income taxes, based on the Corporation’s statutory tax rate as of December 31, 2017. In addition, at December 31, 2017, the Corporation had money market mutual funds with a fair value and amortized cost of $6.0 million which were reclassified to equity securities under this guidance. The Corporation adopted this guidance effective January 1, 2018 with a cumulative-effect adjustment to the balance sheet as of January 1, 2018. The balance in accumulated other comprehensive income of $433 thousand was reclassified to retained earnings effective January 1, 2018. The carrying value of the equity securities, at January 1, 2018, did not change; however, any future increases or decreases in fair value is recorded as an increase or decrease to the carrying value and recognized in other noninterest income. During the nine months ended September 30, 2018 , the Corporation recognized a $26 thousand net gain on equity securities in other noninterest income. In May 2014, the FASB issued ASU No. 2014-09, " Revenue from Contracts with Customers (Topic 606)” and subsequent related updates. The Corporation adopted the guidance effective January 1, 2018 using the modified retrospective method though no adjustments were made to retained earnings as a result of the adoption. The Corporation provided expanded disclosures related to recognition of revenue from contracts with customers. See Note 14, "Revenue from Contracts with Customers." Recent Accounting Pronouncements Yet to Be Adopted In August 2018, the FASB issued ASU No. 2018-14, " Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans." The amendments in this ASU modify the disclosure requirements for employers that sponsor defined benefit plans or other postretirement plans. Disclosures removed by this ASU include the following: 1) amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit costs over the next fiscal year; 2) amount and timing of plan assets expected to be returned to the employer; and 3) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for postretirement health care benefits. Additional disclosures required by this ASU include: 1) the weighted-average interest crediting rates used in an entity's cash balance pension plans and other similar plans and 2) explanations for reasons for significant changes in the benefit obligation or plan assets. All amendments should be applied retrospectively. This ASU is effective for fiscal years ending after December 15, 2020 or December 31, 2020 for the Corporation. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statement disclosures but will result in revised disclosures for retirement plans and other postretirement benefits. In August 2018, the FASB issued ASU No. 2018-13, " Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement." This ASU applies to all entities that are required, under existing GAAP, to make disclosures about recurring or nonrecurring fair value measurements. Disclosures removed by this ASU are the amount and reasons for transfers between Level 1 and Level 2, the policy for timing of transfers between levels and the valuation processes for Level 3 measurements. This ASU modifies disclosures relating to investments in certain entities that calculate net asset value. Additional disclosures required by this ASU include: 1) change in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and 2) range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The prospective method of transition is required for the new disclosure requirements. The other amendments should be applied retrospectively. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years or January 1, 2020 for the Corporation. Early adoption is permitted. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements but will result in revised disclosures for fair value. In August 2017, the FASB issued 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 will adopt this ASU on January 1, 2019 and does not expect the adoption 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 rather than the maturity of the security. Securities within the scope of this guidance are those that have explicit, non-contingent call features that are callable at fixed prices and on preset dates. 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 to retained earnings as of the beginning of the period of adoption. At September 30, 2018 , the Corporation had $11.3 million of callable debt securities. Upon implementation, using the modified retrospective basis effective January 1, 2019, the Corporation expects to record a cumulative-effect adjustment resulting in a reduction in the unamortized premium balance for certain callable debt securities of approximately $50 thousand and a reduction in retained earnings of approximately $40 thousand , net of tax, for the incremental amortization. This estimate could change due to changes in the Corporation's investments in callable securities prior to the adoption date. 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 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 reserve for loan and lease losses will increase upon adoption of CECL and that the increased reserve level will decrease shareholders' equity and regulatory capital and ratios. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" and subsequent related updates to revise the accounting for leases. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases based on the present value of future lease payments. Lessor accounting activities are largely unchanged from existing lease accounting. 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. Early adoption is permitted. This new guidance is effective for the first interim period within annual periods beginning after December 15, 2018, or January 1, 2019 for the Corporation. The Corporation expects to adopt this new guidance effective January 1, 2019, retrospectively at the beginning of the period of adoption through a cumulative-effect adjustment to retained earnings at January 1, 2019. The Corporation expects to elect the package of practical expedients permitted under the transition guidance which among other things, allows carry forward of the historical lease classification. All leases in which the Corporation is the lessee are classified as operating leases and will continue to be classified as such. The Corporation expects to continue to separately account for lease and non-lease components as historically reported and expects to elect the hindsight practical expedient to determine the lease term for existing leases. The Corporation is currently implementing a third party lease accounting system to assist with the measurement of lease liabilities and related right-of-use assets, the post-implementation administration aspect of lease accounting, and the applicable disclosures related to the new guidance. The Corporation has completed the initial scoping phase of the project, including the identification and review of lease contracts applicable to the new guidance, and is in the process of determining the estimated financial statement impact of the new guidance at the transition date. While the Corporation is continuing to assess the impact of this new guidance on the balance sheet and income statement, the Corporation expects to record between $30.0 million to $40.0 million of operating lease liabilities and related right-of-use assets at January 1, 2019, with any difference between these amounts, net of the deferred tax impact, recorded as an adjustment to opening retained earnings. These estimates, based on our active lease portfolio, may change as the Corporation continues through the implementation process, or due to changes in the lease portfolio, which could include new leases, changes in lease commencement dates, and changes to renewal options and lease termination expectations. The initial and continued impact of the recording of operating lease assets will have a negative impact on all Corporation and Bank capital ratios under current regulatory guidance and possibly equity ratios.

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) 2018 2017 2018 2017 Numerator: Net income $ 14,964 $ 11,196 $ 32,171 $ 33,830 Net income allocated to unvested restricted stock (86 ) (96 ) (225 ) (330 ) Net income allocated to common shares $ 14,878 $ 11,100 $ 31,946 $ 33,500 Denominator: Weighted average shares outstanding 29,402 26,666 29,387 26,653 Average unvested restricted stock (170 ) (229 ) (204 ) (265 ) Denominator for basic earnings per share— weighted-average shares outstanding 29,232 26,437 29,183 26,388 Effect of dilutive securities—employee stock options 86 105 92 102 Denominator for diluted earnings per share— adjusted weighted-average shares outstanding 29,318 26,542 29,275 26,490 Basic earnings per share $ 0.51 $ 0.42 $ 1.10 $ 1.27 Diluted earnings per share $ 0.51 $ 0.42 $ 1.09 $ 1.27 Average anti-dilutive options excluded from computation of diluted earnings per share 359 185 315 166

In accordance with ASU 2016-01, beginning January 1, 2018, such amounts were reclassified from investment securities available-for-sale to investments in equity securities on the Corporation's Condensed Consolidated Balance Sheets. Expected maturities may differ from contractual maturities because debt issuers may have the right to call or prepay obligations without call or prepayment penalties and mortgage-backed securities typically prepay at a rate faster than contractually due. Securities with a carrying value of $362.0 million and $345.1 million at September 30, 2018 and December 31, 2017 , respectively, were pledged to secure public deposits and other contractual obligations. In addition, securities of $295 thousand and $1.8 million were pledged to secure credit derivatives and interest rate swaps at September 30, 2018 and December 31, 2017 , respectively. See Note 11, "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, 2018 and 2017 : Nine Months Ended September 30, (Dollars in thousands) 2018 2017 Securities available-for-sale: Proceeds from sales $ 1,010 $ 3,538 Gross realized gains on sales 10 43 Tax expense related to net realized gains on sales 2 15 At September 30, 2018 and December 31, 2017 , 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, 2018 and December 31, 2017 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.

Four federal agency bonds, sixteen investment grade corporate bonds, 114 federal agency residential mortgage securities, nine investment grade municipal bonds and one collateralized mortgage obligation bond had respective unrealized loss positions of $140 thousand , $7.7 million , $6.4 million , $84 thousand and $108 thousand , respectively. The fair value of these 114 securities fluctuate with changes in market conditions which for these underlying securities is primarily due to changes in the interest rate environment. The Corporation does not intend to sell the securities in an unrealized loss position and is unlikely to be required to sell these securities before a recovery of fair value, which may be maturity. Upon review of the attributes of the individual securities, the Corporation concluded these securities were not other-than-temporarily impaired. The Corporation did not recognize any other-than-temporary impairment charges on debt securities for the nine months ended September 30, 2018 and 2017 . In conjunction with the adoption of ASU 2016-01, the Corporation recognized a $26 thousand net gain on equity securities during the nine months ended September 30, 2018 in other noninterest income and the net unrealized gain on equity securities held at September 30, 2018 was $26 thousand . See Note 1, "Summary of Significant Accounting Policies - Accounting Pronouncements Adopted in 2018" for additional information.

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. At September 30, 2018 , approximately $95 thousand in net deferred gains, 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, 2018 . At September 30, 2018 , the notional amount of the interest rate swap was $17.3 million , with a positive fair value of $485 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 $445 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 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 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, 2018 , the Corporation has sixteen variable-rate to fixed-rate interest rate swap transactions between the third-party financial institution and customers with a current notional amount of $84.7 million and remaining maturities ranging from one to 10 years. At September 30, 2018 , the fair value of the swaps to the customers was a liability of $24 thousand and all swaps were in paying positions to the third-party financial institution. 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 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, 2018 and December 31, 2017 . The Corporation pledges cash or securities to cover the negative fair value of derivative instruments.

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, 2018 . 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 $6 thousand at September 30, 2018 . 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. 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. The following table presents the assets and liabilities measured at fair value on a recurring basis at September 30, 2018 and December 31, 2017 , classified using the fair value hierarchy: At September 30, 2018 (Dollars in thousands) Level 1 Level 2 Level 3 Assets/ Assets: Available-for-sale securities: U.S. government corporations and agencies $ — $ 15,316 $ — $ 15,316 State and political subdivisions — 67,892 — 67,892 Residential mortgage-backed securities — 156,414 — 156,414 Collateralized mortgage obligations — 2,981 — 2,981 Corporate bonds — 67,923 26,407 94,330 Total available-for-sale securities — 310,526 26,407 336,933 Equity securities: Equity securities - financial services industry 1,103 — — 1,103 Money market mutual funds 1,161 — — 1,161 Total equity securities 2,264 — — 2,264 Loans* — — 1,801 1,801 Interest rate swaps* — 505 — 505 Interest rate locks with customers* — 305 — 305 Forward loan sale commitments* — 53 — 53 Total assets $ 2,264 $ 311,389 $ 28,208 $ 341,861 Liabilities: Contingent consideration liability $ — $ — $ 310 $ 310 Interest rate swaps* — 20 — 20 Credit derivatives* — — 24 24 Total liabilities $ — $ 20 $ 334 $ 354 At December 31, 2017 (Dollars in thousands) Level 1 Level 2 Level 3 Assets/ Assets: Available-for-sale securities: U.S. government corporations and agencies $ — $ 16,961 $ — $ 16,961 State and political subdivisions — 78,297 — 78,297 Residential mortgage-backed securities — 185,421 — 185,421 Collateralized mortgage obligations — 3,602 — 3,602 Corporate bonds — 79,190 27,986 107,176 Total available-for-sale securities — 363,471 27,986 391,457 Equity securities: Equity securities - financial services industry 1,076 — — 1,076 Money market mutual funds 5,985 — — 5,985 Total equity securities 7,061 — — 7,061 Loans* — — 1,958 1,958 Interest rate swap* — 13 — 13 Interest rate locks with customers* — 527 — 527 Forward loan sale commitments* — 61 — 61 Total assets $ 7,061 $ 364,072 $ 29,944 $ 401,077 Liabilities: Contingent consideration liability $ — $ — $ 339 $ 339 Interest rate swaps* — 50 — 50 Credit derivatives* — — 36 36 Total liabilities $ — $ 50 $ 375 $ 425 * Such financial instruments are recorded at fair value as further described in Note 11, "Derivative Instruments and Hedging Activities."

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, 2018 and December 31, 2017 . Loans and leases held for investment: As of September 30, 2018 , t he 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, adjusted as appropriate to consider credit, liquidity and marketability factors to arrive at a fair value that represents the Corporation's exit price at which these instruments would be sold or transferred. As of December 31, 2017 , t he fair values for loans and leases held for investment were 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 was made for specific credit risks in addition to general portfolio risk and is significant to the valuation. 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, 2018 , impaired loans held for investment had a carrying amount of $28.7 million with a valuation allowance of $1.0 million . At December 31, 2017 , impaired loans held for investment had a carrying amount of $28.5 million with a valuation allowance of $131 thousand . The Corporation had impaired leases of $1.3 million with no reserve at September 30, 2018 and December 31, 2017 . 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, 2018 and December 31, 2017 , servicing rights had a carrying amount of $6.7 million and $6.6 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. During the nine months ended September 30, 2018 , 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 at the lower of the original cost or the current 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 if an agreement of sale does not exist. During the nine months ended September 30, 2018 , two properties had write-downs totaling $503 thousand , four properties were transferred into OREO with a fair value of $477 thousand and three properties were sold with total proceeds of $362 thousand . At September 30, 2018 and December 31, 2017 , OREO had a carrying amount of $1.4 million and $1.8 million , respectively. 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, 2018 , 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 consumer and commercial customers 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. The following table provides total assets by reportable business segment as of the dates indicated.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer	Revenue from Contracts with Customers In May 2014, the FASB issued ASU No. 2014-09, " Revenue from Contracts with Customers (Topic 606)” and subsequent related updates. The Corporation adopted the guidance effective January 1, 2018 using the modified retrospective method though no adjustments were made to retained earnings as a result of the adoption. The Corporation’s revenue is the sum of net interest income and noninterest income. Revenues are recognized when obligations under the terms of contracts with customers are satisfied, including the transfer of control of the promised goods or services to customers, in an amount that reflects the consideration the Corporation expects to be entitled to in exchange for those goods or services. The Corporation provides services to customers which have related performance obligations that are completed to recognize revenue. The Corporation's revenues are generally recognized either immediately upon the completion of the services or over time as the services are performed. Any services performed over time generally require services to be rendered each period and therefore progress in completing these services is measured based upon the passage of time. The following tables disaggregate the Corporation's revenue by major source for the three and nine months ended September 30, 2018 and 2017 .

Noninterest income streams that are out-of-scope of the standard include bank owned life insurance income, sales of investment securities and mortgage banking activities. (2) Other service fee income and other income include certain items that are in scope and certain items that are out of scope of the standard and are described further in the following paragraphs. Banking Segment The Banking segment provides financial services to consumer and commercial customers 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. Service charges on deposit accounts are generally earned on depository accounts for commercial and consumer customers and primarily includes fees for account services, overdraft services, and cash management services for commercial customers. Account services include fees for event-driven services such as ATM transactions and fees for periodic account maintenance activities. Cash management services for commercial customers include fees for event-driven services such as lockbox processing and line sweep services and fees for periodic account maintenance activities. The Corporation's obligation for event-driven services is satisfied at the time of the event when the service is delivered, while the obligation for periodic services is satisfied over the course of each month. Obligations for overdraft services is satisfied at the time of the overdraft. Other service fee income is earned from commercial and consumer customers and primarily includes credit and debit card interchange and merchant revenues, mortgage servicing income, which is out of scope of the standard, and other deposit related service fee income such as wire transfers, check services and safe deposit boxes. Interchange and merchant revenues are recognized concurrently with the delivery of services on a monthly basis. Other deposit related service fee income include fees for event-driven services, such as wire transfers and check services, and fees for periodic services such as safe deposit box services. The obligation for event-driven services is satisfied at the time of the event when the service is delivered, while the obligation for periodic services is satisfied over the course of each month. Other income primarily includes net gains or losses from the sales of loans and leases, net gains or losses from the sales or disposition of fixed assets and net gains or losses on interest rate swaps, all of which are out of scope of the standard, and net gains or losses on sales and write-downs of other real estate owned. Net gains or losses on sales of other real estate owned are recognized at the point in time in which control of the other real estate owned is transferred. Wealth Management Segment 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. Trust fee income is earned for providing trust, investment management and other related services. Obligations for trust and other related services are generally satisfied over time but may be satisfied at points in time for certain activities that are transactional in nature and obligations for investment management services are generally performed over time. Fees for trust fee income are typically based on a tiered scale relative to the market value of assets under management and are recognized in conjunction with the delivery of services. Investment advisory commission and fee income include fees for financial planning, guardian and custodian of employee benefits, investment advisory, and brokerage services. Obligations for financial planning, guardian and custodian of employee benefits, and investment advisory services are generally satisfied over time and fees, typically based on a tiered scale relative to the market value of assets under management are recognized in conjunction with the delivery of services. Brokerage services are typically event driven and are based on the size and number of transactions executed at the client’s direction and recognized on the trade date. Insurance Segment 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. Insurance commission and fee income is derived primarily from commissions from the sale of insurance policies, which are generally calculated as a percentage of the policy premium, and contingent income, which is calculated based on the performance of the policies held by each carrier. Obligations for the sale of insurance policies are generally satisfied at the point in time which the policy is executed and are recognized at the point in time in which the amounts are known and collection is reasonably assured. Obligations for contingent income are generally satisfied over time and are recognized at the point in time in which the amounts are known and collection is reasonably assured. Other service fee income is earned from human resources consulting services. These obligations are generally satisfied over time and are recognized on a periodic basis.

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 nine -month period ended September 30, 2018 are not necessarily indicative of the results that may be expected for the year ended December 31, 2018 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, 2017 , which was filed with the SEC on March 1, 2018 .
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, reserve for loan and lease losses and purchase accounting.
Recent Accounting Pronouncements	In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-02, " Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This ASU clarifies the accounting treatment of the reclassification of certain income tax effects within accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act. The Corporation elected to early adopt this guidance effective January 1, 2018 for all stranded tax effects resulting from tax reform and reclassified stranded tax effects, totaling $3.9 million , from accumulated other comprehensive income to retained earnings. The Corporation's policy for releasing income tax effects from accumulated other comprehensive income is to release such effects on an individual basis as each item is liquidated, sold or extinguished. See Note 10, "Accumulated Other Comprehensive (Loss) Income" for additional detail. 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 Corporation adopted this guidance effective January 1, 2018 with retrospective application for prior period presentation. Effective January 1, 2018, components of net benefit income other than the service cost component are presented in the Corporation's statement of income in other noninterest expense rather than in salaries, benefits and commission expense. Prior period components of net benefit income other than the service cost component were reclassed to other noninterest expense in the Corporation's statement of income. 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 requires equity investments to be measured at fair value with changes in fair value recognized in net income. At December 31, 2017 , the Corporation had financial services equity securities with a carrying value of $1.1 million which included an unrealized net gain of $666 thousand . At December 31, 2017 , $433 thousand was recorded in accumulated other comprehensive income which represented the unrealized net gain, net of income taxes, based on the Corporation’s statutory tax rate as of December 31, 2017. In addition, at December 31, 2017, the Corporation had money market mutual funds with a fair value and amortized cost of $6.0 million which were reclassified to equity securities under this guidance. The Corporation adopted this guidance effective January 1, 2018 with a cumulative-effect adjustment to the balance sheet as of January 1, 2018. The balance in accumulated other comprehensive income of $433 thousand was reclassified to retained earnings effective January 1, 2018. The carrying value of the equity securities, at January 1, 2018, did not change; however, any future increases or decreases in fair value is recorded as an increase or decrease to the carrying value and recognized in other noninterest income. During the nine months ended September 30, 2018 , the Corporation recognized a $26 thousand net gain on equity securities in other noninterest income. In May 2014, the FASB issued ASU No. 2014-09, " Revenue from Contracts with Customers (Topic 606)” and subsequent related updates. The Corporation adopted the guidance effective January 1, 2018 using the modified retrospective method though no adjustments were made to retained earnings as a result of the adoption. The Corporation provided expanded disclosures related to recognition of revenue from contracts with customers. See Note 14, "Revenue from Contracts with Customers." Recent Accounting Pronouncements Yet to Be Adopted In August 2018, the FASB issued ASU No. 2018-14, " Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans." The amendments in this ASU modify the disclosure requirements for employers that sponsor defined benefit plans or other postretirement plans. Disclosures removed by this ASU include the following: 1) amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit costs over the next fiscal year; 2) amount and timing of plan assets expected to be returned to the employer; and 3) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for postretirement health care benefits. Additional disclosures required by this ASU include: 1) the weighted-average interest crediting rates used in an entity's cash balance pension plans and other similar plans and 2) explanations for reasons for significant changes in the benefit obligation or plan assets. All amendments should be applied retrospectively. This ASU is effective for fiscal years ending after December 15, 2020 or December 31, 2020 for the Corporation. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statement disclosures but will result in revised disclosures for retirement plans and other postretirement benefits. In August 2018, the FASB issued ASU No. 2018-13, " Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement." This ASU applies to all entities that are required, under existing GAAP, to make disclosures about recurring or nonrecurring fair value measurements. Disclosures removed by this ASU are the amount and reasons for transfers between Level 1 and Level 2, the policy for timing of transfers between levels and the valuation processes for Level 3 measurements. This ASU modifies disclosures relating to investments in certain entities that calculate net asset value. Additional disclosures required by this ASU include: 1) change in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and 2) range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The prospective method of transition is required for the new disclosure requirements. The other amendments should be applied retrospectively. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years or January 1, 2020 for the Corporation. Early adoption is permitted. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements but will result in revised disclosures for fair value. In August 2017, the FASB issued 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 will adopt this ASU on January 1, 2019 and does not expect the adoption 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 rather than the maturity of the security. Securities within the scope of this guidance are those that have explicit, non-contingent call features that are callable at fixed prices and on preset dates. 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 to retained earnings as of the beginning of the period of adoption. At September 30, 2018 , the Corporation had $11.3 million of callable debt securities. Upon implementation, using the modified retrospective basis effective January 1, 2019, the Corporation expects to record a cumulative-effect adjustment resulting in a reduction in the unamortized premium balance for certain callable debt securities of approximately $50 thousand and a reduction in retained earnings of approximately $40 thousand , net of tax, for the incremental amortization. This estimate could change due to changes in the Corporation's investments in callable securities prior to the adoption date. 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 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 reserve for loan and lease losses will increase upon adoption of CECL and that the increased reserve level will decrease shareholders' equity and regulatory capital and ratios. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" and subsequent related updates to revise the accounting for leases. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases based on the present value of future lease payments. Lessor accounting activities are largely unchanged from existing lease accounting. 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. Early adoption is permitted. This new guidance is effective for the first interim period within annual periods beginning after December 15, 2018, or January 1, 2019 for the Corporation. The Corporation expects to adopt this new guidance effective January 1, 2019, retrospectively at the beginning of the period of adoption through a cumulative-effect adjustment to retained earnings at January 1, 2019. The Corporation expects to elect the package of practical expedients permitted under the transition guidance which among other things, allows carry forward of the historical lease classification. All leases in which the Corporation is the lessee are classified as operating leases and will continue to be classified as such. The Corporation expects to continue to separately account for lease and non-lease components as historically reported and expects to elect the hindsight practical expedient to determine the lease term for existing leases. The Corporation is currently implementing a third party lease accounting system to assist with the measurement of lease liabilities and related right-of-use assets, the post-implementation administration aspect of lease accounting, and the applicable disclosures related to the new guidance. The Corporation has completed the initial scoping phase of the project, including the identification and review of lease contracts applicable to the new guidance, and is in the process of determining the estimated financial statement impact of the new guidance at the transition date. While the Corporation is continuing to assess the impact of this new guidance on the balance sheet and income statement, the Corporation expects to record between $30.0 million to $40.0 million of operating lease liabilities and related right-of-use assets at January 1, 2019, with any difference between these amounts, net of the deferred tax impact, recorded as an adjustment to opening retained earnings. These estimates, based on our active lease portfolio, may change as the Corporation continues through the implementation process, or due to changes in the lease portfolio, which could include new leases, changes in lease commencement dates, and changes to renewal options and lease termination expectations. The initial and continued impact of the recording of operating lease assets will have a negative impact on all Corporation and Bank capital ratios under current regulatory guidance and possibly equity ratios.

Earnings Per Share, Basic and Diluted [Abstract]
Summary of Computation for Basic and Diluted 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) 2018 2017 2018 2017 Numerator: Net income $ 14,964 $ 11,196 $ 32,171 $ 33,830 Net income allocated to unvested restricted stock (86 ) (96 ) (225 ) (330 ) Net income allocated to common shares $ 14,878 $ 11,100 $ 31,946 $ 33,500 Denominator: Weighted average shares outstanding 29,402 26,666 29,387 26,653 Average unvested restricted stock (170 ) (229 ) (204 ) (265 ) Denominator for basic earnings per share— weighted-average shares outstanding 29,232 26,437 29,183 26,388 Effect of dilutive securities—employee stock options 86 105 92 102 Denominator for diluted earnings per share— adjusted weighted-average shares outstanding 29,318 26,542 29,275 26,490 Basic earnings per share $ 0.51 $ 0.42 $ 1.10 $ 1.27 Diluted earnings per share $ 0.51 $ 0.42 $ 1.09 $ 1.27 Average anti-dilutive options excluded from computation of diluted earnings per share 359 185 315 166

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, 2018 and December 31, 2017 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.

Four federal agency bonds, sixteen investment grade corporate bonds, 114 federal agency residential mortgage securities, nine investment grade municipal bonds and one collateralized mortgage obligation bond had respective unrealized loss positions of $140 thousand , $7.7 million , $6.4 million , $84 thousand and $108 thousand , respectively. The fair value of these 114 securities fluctuate with changes in market conditions which for these underlying securities is primarily due to changes in the interest rate environment. The Corporation does not intend to sell the securities in an unrealized loss position and is unlikely to be required to sell these securities before a recovery of fair value, which may be maturity. Upon review of the attributes of the individual securities, the Corporation concluded these securities were not other-than-temporarily impaired. The Corporation did not recognize any other-than-temporary impairment charges on debt securities for the nine months ended September 30, 2018 and 2017 . In conjunction with the adoption of ASU 2016-01, the Corporation recognized a $26 thousand net gain on equity securities during the nine months ended September 30, 2018 in other noninterest income and the net unrealized gain on equity securities held at September 30, 2018 was $26 thousand . See Note 1, "Summary of Significant Accounting Policies - Accounting Pronouncements Adopted in 2018" for additional information.
