Summary of Significant Accounting Policies	'
	Note 1. 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) and its wholly owned subsidiaries; the Corporation’s primary 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-month period ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ended December 31, 2014. 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, 2013, which was filed with the SEC on March 4, 2014.
	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, valuation of goodwill and other intangible assets, mortgage servicing rights, deferred tax assets and liabilities, benefit plans and stock-based compensation expense.
	Recent Accounting Pronouncements
	In January 2014, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU) regarding reclassification of residential real estate collateralized consumer mortgage loans upon foreclosure. The ASU clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The ASU was issued to eliminate diversity in practice on this topic. The amendment is effective for fiscal years and interim periods within those years beginning after December 15, 2014, or January 1, 2015 for the Corporation. The Corporation does not anticipate the adoption of this guidance will have a material impact on its financial statements but will result in expanded disclosures effective March 31, 2015.

Acquisition	'
	Note 2. Acquisition
	On January 27, 2014, the Corporation completed the acquisition of Girard Partners, a registered investment advisory firm with more than $500 million in assets under management. The Corporation increased its assets under management to over $3.0 billion at the acquisition date and expanded its advisory capabilities.
	The Corporation paid $5.4 million in cash at closing with additional contingent consideration to be paid in annual installments over the five-year period ending December 31, 2018 based on the achievement of certain levels of EBITDA (earnings before interest, taxes, depreciation and amortization). As of the effective date of the acquisition, January 1, 2014, the Corporation recorded the estimated fair value of the contingent consideration of $5.5 million in other liabilities. The potential cash payments that could result from the contingent consideration arrangement range from $0 to a maximum of $14.5 million cumulative over the next five years. As a result of the Girard Partners acquisition, the Corporation recorded goodwill of $6.8 million (inclusive of the contingent consideration) and customer related intangibles of $4.3 million. The goodwill is expected to be deductible for tax purposes. The customer related intangibles are being amortized over nine years using the sum-of-the-years-digits amortization method.

	Expected maturities may differ from contractual maturities because debt issuers may have the right to call or prepay obligations without call or prepayment penalties. Unrealized losses in investment securities at March 31, 2014 and December 31, 2013 do not represent other-than-temporary impairments.
	Securities with a carrying value of $247.5 million and $271.1 million at March 31, 2014 and December 31, 2013, respectively, were pledged to secure public deposits and for other purposes as required by law.
	The following table presents information related to sales of securities available-for-sale during the three months ended March 31, 2014 and 2013:

	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 and considers the current economic conditions, the length of time and the extent to which the fair value has been less than cost, interest rates and the bond rating of each security. All of the debt securities are rated as investment grade and management believes that it will not incur any losses. The unrealized losses on the Corporation’s investments in debt securities are temporary in nature since they are primarily related to market interest rates and are not related to the underlying credit quality of the issuers within our investment portfolio. 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 three months ended March 31, 2014 and 2013.
	At March 31, 2014 and December 31, 2013, 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 March 31, 2014 and December 31, 2013 by the length of time those securities were in a continuous loss position:

Credit Quality Indicators
The following tables present by class, the recorded investment in loans and leases held for investment by credit quality indicator at March 31, 2014 and December 31, 2013.
The Corporation employs a ten (10) grade risk rating system related to the credit quality of commercial loans and residential real estate loans secured for a business purpose of which the first six categories are pass categories (credits not adversely rated). The following is a description of the internal risk ratings and the likelihood of loss related to each risk rating. Loans with risk ratings of one through five are reviewed based on the relationship dollar amount with the borrower: loans with a relationship total of $2.5 million or greater are reviewed quarterly; loans with a relationship balance of less than $2.5 million but greater than $500 thousand are reviewed annually based on the borrower’s fiscal year; loans with a relationship balance of less than $500 thousand are reviewed only if the loan becomes 60 days or more past due. Loans with risk ratings of six are also reviewed based on the relationship dollar amount with the borrower: loans with a relationship balance of $2.0 million or greater are reviewed quarterly; loans with a relationship balance of less than $2.0 million but greater than $500 thousand are reviewed annually; loans with a relationship balance of less than $500 thousand are reviewed only if the loan becomes 60 days or more past due. Loans with risk ratings of seven are reviewed at least quarterly, and as often as monthly, at management’s discretion. Loans with risk ratings of eight through ten are reviewed monthly.
	1	Cash Secured – No credit risk
	2	Fully Secured – Negligible credit risk
	3	Strong – Minimal credit risk
	4	Satisfactory – Nominal credit risk
	5	Acceptable – Moderate credit risk
	6	Pre-Watch – Marginal, but stable credit risk
	7	Special Mention – Potential weakness
	8	Substandard – Well-defined weakness
	9	Doubtful – Collection in-full improbable
	10	Loss – Considered uncollectible

Credit Exposure – Real Estate—Residential Secured for Personal Purpose, Real Estate—Home Equity Secured for Personal Purpose, Loans to individuals, Lease Financing Credit Risk Profile by Payment Activity
The Corporation monitors the credit risk profile by payment activity for the following classifications of loans and leases: residential real estate loans secured for a personal purpose, home equity loans secured for a personal purpose, loans to individuals and lease financings. Nonperforming loans and leases are loans past due 90 days or more, loans and leases on nonaccrual of interest and troubled debt restructured loans and lease modifications. Performing loans and leases are reviewed only if the loan becomes 60 days or more past due. Nonperforming loans and leases are reviewed monthly. Performing loans and leases have a nominal to moderate risk of loss. Nonperforming loans and leases are loans or leases with a well-defined weakness and where collection in-full is improbable.

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

Impaired loans includes nonaccrual loans and leases, accruing troubled debt restructured loans and lease modifications and other accruing impaired loans for which it is probable that not all principal and interest payments due will be collectible in accordance with the contractual terms. These loans are individually measured to determine the amount of potential impairment. The loans are reviewed for impairment based on the fair value of the collateral for collateral dependent loans and for certain loans based on discounted cash flows using the loans’ initial effective interest rates. Impaired loans included other accruing impaired loans of $27.4 million and $27.5 million at March 31, 2014 and December 31, 2013, respectively. Specific reserves on other accruing impaired loans were $739 thousand and $1.6 million at March 31, 2014 and December 31, 2013, respectively.
The following presents by class of loans, the average recorded investment in impaired loans and an analysis of interest on impaired loans. A loan may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. Therefore, interest income on accruing impaired loans is recognized using the accrual method.

The Corporation grants concessions primarily related to extensions of interest-only payment periods and an occasional payment modification. These modifications typically are for a short-term basis up to one year. Our goal when restructuring a credit is to afford the customer a reasonable period of time to provide cash flow relief to customers experiencing cash flow difficulties. Accruing troubled debt restructured loans are primarily comprised of loans on which interest is being accrued under the restructured terms, and the loans are current or less than ninety days past due.
The following presents, by class of loans, information regarding the types of concessions granted on accruing and nonaccrual loans that were restructured during the three months ended March 31, 2014. There were no troubled debt loan restructurings during the three months ended March 31, 2013.

Mortgage Servicing Rights	'
	Note 5. Mortgage Servicing Rights
	The Corporation has originated mortgage servicing rights which are included in other intangible assets on the consolidated balance sheets. Mortgage servicing rights are amortized in proportion to, and over the period of, estimated net servicing income on a basis similar to the interest method and an accelerated amortization method for loan payoffs. Mortgage servicing rights are subject to impairment testing on a quarterly basis. The aggregate fair value of these rights was $7.2 million at both March 31, 2014 and December 31, 2013. The fair value of mortgage servicing rights was determined using discount rates ranging from 5.1% to 10.0% at March 31, 2014 and 5.0% to 10.0% at December 31, 2013.

Derivative Instruments and Hedging Activities	'
	Note 10. Derivative Instruments and Hedging Activities
	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.
	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.
	The following table presents the notional amounts and fair values of derivatives not designated as hedging instruments recorded on the consolidated balance sheets at March 31, 2014 and December 31, 2013:

Fair Value Disclosures	'
	Note 11. 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 its 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 the 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 close of business at period end. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Examples of instruments, which would generally be classified within Level 2 of the valuation hierarchy, include securities issued by U.S. Government sponsored enterprises, mortgage-backed securities, collateralized mortgage obligations, corporate and municipal bonds and certain equity securities. In cases where there is limited activity or less transparency around inputs to the valuation, investment securities are classified within Level 3 of the valuation hierarchy.
	Fair values for securities are determined using independent pricing services and market-participating brokers. The Corporation’s independent pricing service utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information for structured securities, cash flow and, when available, loan performance data. Because many fixed income securities do not trade on a daily basis, the pricing service’s evaluated pricing applications apply information as applicable through processes, such as benchmarking of like securities, sector groupings, and matrix pricing, to prepare evaluations. If at any time, the pricing service determines that it does have not sufficient verifiable information to value a particular security, the Corporation will utilize valuations from another pricing service. Management has a sufficient understanding of the third party service’s valuation models, assumptions and inputs used in determining the fair value of securities to enable management to maintain an appropriate system of internal control.
	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. Additionally, on an annual basis, the Corporation has its security portfolio priced by a second pricing service to determine consistency with another market evaluator, except for municipal bonds which are priced by another service provider on a sample basis. If, upon the Corporation’s review or in comparing with another servicer, a material difference between pricing evaluations were to exist, the Corporation may submit an inquiry to its current pricing service regarding the data used to make the valuation of a particular security. If the Corporation determines it has market information that would support a different valuation than its current pricing service’s evaluation it can submit a challenge for a change to that security’s valuation. There were no material differences in valuations noted at March 31, 2014.
	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. Derivative financial instruments are classified within Level 2 of the valuation hierarchy.
	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 in the discount rate or 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.
	For the Girard Partners acquisition, the potential cash payments that could result from the contingent consideration arrangement range from $0 to a maximum of $14.5 million cumulative over the five-year period ending December 31, 2018.
	For the John T. Fretz Insurance Agency acquisition, the potential future cash payments that could result from the contingent consideration arrangement range from $0 to a maximum of $930 thousand cumulative over the three-year period ending April 30, 2016.
	For the Javers Group acquisition, the Corporation recorded a reduction to the contingent liability during the second quarter of 2013 which resulted in a reduction of other noninterest expense of $959 thousand. The adjustment reflects that revenue levels necessary for an earn-out payment in the first year post-acquisition were not met and that revenue growth levels necessary to qualify for subsequent years’ earn-out payments to be made are remote. Therefore, as of March 31, 2014, the fair value of this contingent consideration liability is $0. The Javers’ original contingent consideration arrangement ranged from $0 to a maximum of $1.7 million cumulative over the three-year period ending June 30, 2015.
	The following table presents the assets and liabilities measured at fair value on a recurring basis at March 31, 2014 and December 31, 2013, classified using the fair value hierarchy:

The following valuation methods and assumptions were used by the Corporation in estimating its fair value for financial instruments measured at fair value on a non-recurring basis and financial instruments not measured at fair value on a recurring or non-recurring basis in the Corporation’s consolidated balance sheets but for which the fair value is required to be disclosed:
Cash and short-term interest-earning assets: The carrying amounts reported in the balance sheet for cash and due from banks, interest-earning deposits with other banks, and other short-term investments approximates those assets’ fair values. 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.
Loans held for sale: The fair value of the Corporation’s 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. The Corporation’s loans held for sale 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 March 31, 2014 and December 31, 2013.
Loans and leases held for investment: The fair values for loans 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 held for investment: Impaired loans held for investment include those collateral-dependent loans for which the practical expedient was applied, resulting in a fair-value adjustment to the loan. Impaired loans are evaluated and valued at the time the loan is identified as impaired, at the lower of cost or fair value. Fair value is measured based on the value of the collateral securing these loans less cost to sell and is classified at a Level 3 in the fair value hierarchy. The fair value of collateral is based on appraisals performed by qualified licensed appraisers hired by the Corporation. At March 31, 2014, impaired loans held for investment had a carrying amount of $53.4 million with a valuation allowance of $1.6 million. At December 31, 2013, impaired loans held for investment had a carrying amount of $58.3 million with a valuation allowance of $3.0 million.
Mortgage servicing rights: The Corporation estimates the fair value of mortgage servicing rights using discounted cash flow models that calculate the present value of estimated future net servicing income. The model uses readily available prepayment speed assumptions for the current interest rates of the portfolios serviced. Mortgage servicing rights are classified within Level 2 of the valuation hierarchy. The Corporation reviews the mortgage servicing rights portfolio on a quarterly basis for impairment and the mortgage servicing rights are carried at the lower of amortized cost or estimated fair value. At March 31, 2014, mortgage servicing rights had a carrying amount of $5.6 million with a valuation allowance of $243 thousand. At December 31, 2013, mortgage servicing rights had a carrying amount of $5.8 million with a valuation allowance of $250 thousand.
Goodwill and other identifiable intangible 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 three months ended March 31, 2014, 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 is estimated based upon its appraised value less costs to sell. The real estate is stated at an amount equal to the loan balance prior to foreclosure, plus costs incurred for improvements to the property but no more than the fair value of the property, less estimated costs to sell. New appraisals are generally obtained on an annual basis. Other real estate owned is classified within Level 2 of the valuation hierarchy.
Deposit liabilities: The fair values for demand and savings accounts, with no stated maturities, is the amount payable on demand at the reporting date (carrying value) and are classified within Level 1 in the fair value hierarchy. The fair values for time deposits with fixed maturities are estimated by discounting the final maturity using interest rates currently offered for deposits with similar remaining maturities. Time deposits are classified within Level 2 in the fair value hierarchy.
Short-term borrowings: The fair value of customer repurchase agreements are estimated using current market rates for similar borrowings and are classified within Level 2 in the fair value hierarchy. Short-term FHLB advances are estimated using a discounted cash flow analysis based on current market rates for similar borrowings, and include components for operating expense and embedded prepayment options that are observable. Short-term FHLB advances 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.

	Principles of Consolidation and Basis of Presentation
	The accompanying unaudited consolidated financial statements include the accounts of Univest Corporation of Pennsylvania (the Corporation) and its wholly owned subsidiaries; the Corporation’s primary 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-month period ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ended December 31, 2014. 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, 2013, which was filed with the SEC on March 4, 2014.
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, valuation of goodwill and other intangible assets, mortgage servicing rights, deferred tax assets and liabilities, benefit plans and stock-based compensation expense.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In January 2014, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU) regarding reclassification of residential real estate collateralized consumer mortgage loans upon foreclosure. The ASU clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The ASU was issued to eliminate diversity in practice on this topic. The amendment is effective for fiscal years and interim periods within those years beginning after December 15, 2014, or January 1, 2015 for the Corporation. The Corporation does not anticipate the adoption of this guidance will have a material impact on its financial statements but will result in expanded disclosures effective March 31, 2015.
