The Corporation’s former subsidiary, Univest Delaware, Inc., was dissolved during 2013. Univest Investments, Univest Insurance and Univest Capital do not currently meet the quantitative and qualitative thresholds for separate disclosure provided as a business segment. Therefore, the Corporation currently has one reportable segment, “Community Banking,” and strategically this is how the Corporation operates and has positioned itself in the marketplace. The Corporation’s activities are interrelated, each activity is dependent, and performance is assessed based on how each of these activities supports the others. Accordingly, significant operating decisions are based upon analysis of the Corporation as one Community Banking operating segment. The Bank serves Montgomery, Bucks, Chester and Lehigh counties of Pennsylvania through thirty-one banking offices and provides banking and trust services to the residents and employees of twelve retirement communities. Banking services are also available on-line at the Corporation’s website at www.univest.net.

	Principles of Consolidation

	The consolidated financial statements include the accounts of the Corporation and its wholly owned subsidiary, the Bank. All significant intercompany balances and transactions have been eliminated in consolidation and certain prior period amounts have been reclassified to conform to current-year presentation.

	Use of Estimates

	The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include fair value measurement of investment securities available-for- sale and assessment for impairment of certain investment securities, reserve for loan and lease losses, valuation of goodwill and other intangible assets, mortgage servicing rights, deferred tax assets and liabilities, benefit plans and stock-based compensation expense.

	Interest-earning Deposits with Other Banks

	Interest-earning deposits with other banks consist of deposit accounts with other financial institutions generally having maturities of three months or less.

	Investment Securities

	Securities are classified as investment securities held-to-maturity and carried at amortized cost if management has the positive intent and ability to hold the securities to maturity. Securities purchased with the intention of recognizing short-term profits are placed in the trading account and are carried at fair value. The Corporation did not have any trading account securities at December 31, 2013 or 2012. Securities not classified as held-to-maturity or trading are designated securities available-for-sale and carried at fair value with unrealized gains and losses reflected in other comprehensive income, net of estimated income taxes. Realized gains and losses on the sale of investment securities are recognized using the specific identification method and are included in the consolidated statements of income. The amortization of premiums and accretion of discounts are included in interest income and calculated using the level yield method.



	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 credit portion of any loss on debt securities is recognized through earnings and the noncredit portion of any loss related to debt securities that the Corporation does not intend to sell, and it is more likely than not that the Corporation will not be required to sell the securities prior to recovery, is recognized in other comprehensive income, net of tax. The Corporation did not recognize any other-than-temporary impairment charges on debt securities during the years of 2011 through 2013.

	The Corporation evaluates its equity securities for other-than-temporary impairment and recognizes other-than-temporary impairment charges when it has determined that it is probable that the fair value of certain equity securities will not recover to the Corporation’s cost basis in the individual securities within a reasonable period of time due to a decline in the financial stability of the underlying companies. Management evaluates the near-term prospects of the issuers in relation to the severity and duration of the impairment. The Corporation has the intent and ability to hold these securities until recovery of the Corporation’s cost basis occurs.

	Loans and Leases

	Loans and leases are stated at the principal amount less net deferred fees and unearned discount. Interest income on commercial, consumer, and mortgage loans is recorded on the outstanding balance method, using actual interest rates applied to daily principal balances. Loan commitments are made to accommodate the financial needs of the customers. These commitments represent off-balance sheet items that are unfunded. Accrual of interest income on loans and leases ceases when collectability of interest and/or principal is questionable. If it is determined that the collection of interest previously accrued is uncertain, such accrual is reversed and charged to current earnings. Loans and leases are considered past due based upon failure to comply with contractual terms.

	A loan or lease is typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest, even though the loan or lease is currently performing. When a loan or lease, including an impaired loan or lease, is classified as nonaccrual, the accrual of interest on such a loan or lease is discontinued. A loan or lease may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan or lease is placed on nonaccrual status, unpaid interest credited to income in the current year is reversed. Interest received on nonaccrual loans and leases is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Loans and leases are usually restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. A loan or lease is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the loan agreement. Interest on impaired loans and leases, which are not classified as nonaccrual, is recognized on the accrual basis.

	Loan and Lease Fees

	Fees collected upon loan or lease origination and certain direct costs of originating loans and leases are deferred and recognized over the contractual lives of the related loans and leases as yield adjustments using the interest method. Upon prepayment or other disposition of the underlying loans and leases before their contractual maturities, any associated unearned fees or unamortized costs are recognized.

	Reserve for Loan and Lease Losses

	The reserve for loan and lease losses is maintained at a level that management believes is appropriate to absorb known and inherent losses in the loan and lease portfolio. Management’s methodology to determine the adequacy of and the provision to the reserve considers specific credit reviews, past loan and lease loss experience, current economic conditions and trends and the volume, growth, and composition of the loan portfolio.



	The reserve for loan and lease losses is determined through a monthly evaluation of reserve adequacy. This analysis takes into consideration the growth of the loan and lease portfolio, the status of past-due loans and leases, current economic conditions, various types of lending activity, policies, real estate and other loan commitments, and significant changes in charge-off activity. Impaired loans, including nonaccrual loans and leases, troubled debt restructured loans and other accruing impaired loans are evaluated individually. All other loans and leases are evaluated as pools. Based on historical loss experience and qualitative factors, loss factors are determined giving consideration to the areas noted in the first paragraph and applied to the pooled loan and lease categories to develop the general or allocated portion of the reserve. Loss factors are updated quarterly. Historical loss experience is comprised of losses aggregated over eight quarters. Management also reviews the activity within the reserve to determine what actions, if any, should be taken to address differences between estimated and actual losses. Any of the above factors may cause the provision to fluctuate.

	The reserve for loan and lease losses is based on management’s evaluation of the loan and lease portfolio under current economic conditions and such other factors, which deserve recognition in estimating loan and lease losses. This evaluation is inherently subjective, as it requires estimates including the amounts and timing of future cash flows expected to be received on impaired loans and leases that may be susceptible to significant change. Additions to the reserve arise from the provision for loan and lease losses charged to operations or from the recovery of amounts previously charged off. Loan and lease charge-offs reduce the reserve. Loans and leases are charged off when there has been permanent impairment or when in the opinion of management the full amount of the loan or lease will not be realized. Certain impaired loans are reported at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent, or for certain impaired loans, at the present value of expected future cash flows using the loan’s initial effective interest rate. For commercial impaired loans which are collateral dependent, the fair value of collateral is based on appraisals performed by qualified licensed appraisers hired by the Corporation less management’s estimated costs to sell. Appraisals are updated annually and obtained more frequently if changes in the property or market conditions warrant. Once an updated appraisal is received, if the fair value less estimated costs to sell is less than the carrying amount of the collateral dependent loan, a charge-off to the reserve for loan and lease losses is recorded for the difference.

	The reserve for loan and lease losses consists of an allocated reserve and an unallocated reserve. The allocated reserve is comprised of reserves established on specific loans and leases, and class reserves based on historical loan and lease loss experience, current trends, and management assessments. The unallocated reserve is based on both general economic conditions and other risk factors in the Corporation’s individual markets and portfolios.

	The specific reserve element is based on a regular analysis of impaired commercial and real estate loans. For these loans, the specific reserve established is based on a careful analysis of related collateral value, cash flow considerations and, if applicable, guarantor capacity.

	The class reserve element is determined by an internal loan and lease grading process in conjunction with associated allowance factors. The Corporation revises the class allowance factors whenever necessary in order to address improving or deteriorating credit quality trends or specific risks associated with a given loan or lease pool classification.

	The Corporation maintains an unallocated reserve to recognize the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and allocated losses in the portfolio. There are many factors considered such as the inherent delay in obtaining information regarding a customer’s financial condition or changes in their business condition, the judgmental nature of loan and lease evaluations, the delay in the interpretation of economic trends and the judgmental nature of collateral assessments. The Corporation also maintains a reserve in other liabilities for off-balance sheet credit exposures that currently are unfunded in categories with historical loss experience. In addition, the Bank’s primary examiner, as a regular part of their examination process, may require the Bank to increase the level of reserves.

	Premises and Equipment

	Land is stated at cost, and premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method and charged to operating expenses over the estimated useful lives of the assets. The estimated useful life for new buildings constructed on land owned is forty years, and for new buildings constructed on leased land, is the lesser of forty years or the lease term including anticipated renewable terms. The useful life of purchased existing buildings is the estimated remaining useful life at the time of the purchase. Land improvements are considered to have estimated useful lives of fifteen years or the lease term including anticipated renewable terms. Furniture, fixtures and equipment have estimated useful lives ranging from three to ten years.



Goodwill and Other Intangible Assets

The Corporation accounts for its acquisitions using the purchase accounting method. Purchase accounting requires the total purchase price to be allocated to the estimated fair values of assets acquired and liabilities assumed, including certain intangible assets that must be recognized. Typically, this allocation results in the purchase price exceeding the fair value of net assets acquired, which is recorded as goodwill. Core deposit intangibles are a measure of the value of checking, money market and savings deposits acquired in business combinations accounted for under the purchase method. Core deposit intangibles and other identified intangibles with finite useful lives are amortized using the sum of the year’s digits over their estimated useful lives of up to fifteen years. Customer related intangibles are amortized over their estimated useful lives of five to twelve years. Covenants not to compete are amortized over their three to five-year contractual lives. The Corporation completes a goodwill analysis at least on an annual basis or more often if events and circumstances indicate that there may be impairment. The Corporation also completes an impairment test for other intangible assets on an annual basis or more often if events and circumstances indicate a possible impairment. There can be no assurance that future impairment analyses will not result in a charge to earnings.

Mortgage servicing rights are recognized as separate assets when mortgage loans are sold and the servicing rights are retained. Capitalized mortgage servicing rights are reported in other intangible assets and are amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing period of the underlying mortgage loans. Mortgage servicing rights are evaluated for impairment, on a quarterly basis, based upon the fair value of the servicing rights as compared to amortized cost. The Corporation estimates the fair value of mortgage servicing rights using discounted cash flow models that calculate the present value of estimated future net servicing income. The model uses readily available prepayment speed assumptions for the current interest rates of the portfolios serviced. Mortgage servicing rights are carried at the lower of amortized cost or estimated fair value. Impairment is recognized through a valuation allowance, to the extent that fair value is less than the unamortized capitalized amount.

Bank Owned Life Insurance

The Corporation carries bank owned life insurance (BOLI) at the net cash surrender value of the policies. Changes in the net cash surrender value of these policies are reflected in noninterest income. Proceeds from and purchases of bank owned life insurance are reflected in the statement of cash flows under investing activities. The Corporation recognizes a liability for the future death benefit for certain endorsement split-dollar life insurance arrangements that provide an employee with a death benefit in a postretirement/ termination period.

Other Real Estate Owned

Other real estate owned represents properties acquired through customers’ loan defaults and is included in other assets. 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. Any write-down, at or prior to the dates the real estate is considered foreclosed, is charged to the allowance for loan losses. Subsequent write-downs and any gain or loss upon the sale of real estate owned is recorded in other noninterest income. Expenses incurred in connection with holding such assets are recorded in other noninterest expense.

Derivative Financial Instruments

The Corporation recognizes all derivative financial instruments on its balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through income. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative are either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings, or recognized in other comprehensive income until the underlying forecasted transaction is recognized in earnings. The ineffective portion of a derivative’s change in fair value is recognized in earnings immediately. To determine fair value, the Corporation uses third party pricing models that incorporate assumptions about market conditions and risks that are current at the reporting date.

The Corporation may use interest-rate swap agreements to modify interest rate characteristics from variable to fixed or fixed to floating in order to reduce the impact of interest rate changes on future net interest income. The Corporation accounts for its interest-rate swap contracts in cash flow hedging relationships by establishing and documenting the effectiveness of the instrument in offsetting the change in cash flows of assets or liabilities that are being hedged. To determine effectiveness, the Corporation performs an analysis to identify if changes in fair value or cash flow of the derivative correlate to the equivalent changes in the forecasted interest receipts related to a specified hedged item. Recorded amounts related to interest-rate swaps are included in other assets or liabilities. The change in fair value of the ineffective part of the instrument would need to be charged to the statement of operations, potentially causing material fluctuations in reported earnings in the period of the change relative to comparable periods. In a fair value hedge, the fair values of the interest rate swap agreements and changes in the fair values of the hedged items are recorded in the Corporation’s consolidated balance sheet with the corresponding gain or loss being recognized in the consolidated statement of operations. The difference between changes in the fair values of interest rate swap agreements and the hedged items represents hedge ineffectiveness and is recorded in net interest income in the statement of operations. The Corporation performs an assessment, both at the inception of the hedge and quarterly thereafter, to determine whether these derivatives are highly effective in offsetting changes in the value of the hedged items.

In connection with its mortgage banking activities, the Corporation enters into commitments to originate certain fixed-rate residential mortgage loans for customers, also referred to as interest rate locks. In addition, the Corporation enters into forward commitments for the future sale or purchase of mortgage loans to or from third-party investors to hedge the effect of changes in interest rates on the value of the interest rate locks. Forward loan sale commitments may also be in the form of commitments to sell individual mortgage loans at a fixed price at a future date. Both the interest rate locks and the forward loan sale commitments are accounted for as derivatives and carried at fair value, determined as the amount that would be necessary to settle each derivative financial instrument at the balance sheet date. Gross derivative assets and liabilities are recorded within other assets and other liabilities on the consolidated balance sheets, with changes in fair value during the period recorded within the net gain on mortgage banking activities on the consolidated statements of operations.

Federal Home Loan Bank Stock, Federal Reserve Bank Stock and Certain Other Investments without Readily Determinable Fair Values

Federal Home Loan Bank stock, Federal Reserve Bank stock and certain other investments without readily determinable fair values are classified as other assets on the consolidated balance sheets. These investments are carried at cost and evaluated for impairment periodically or if events or circumstances indicate that there may be impairment.

Income Taxes

There are two components of income tax expense: current and deferred. Current income tax expense approximates cash to be paid or refunded for taxes for the applicable period. Deferred income taxes are provided for temporary differences between amounts reported for financial statement and tax purposes. Deferred income taxes are computed using the asset and liability method, such that deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between financial reporting amounts and the tax basis of existing assets and liabilities based on currently enacted tax laws and tax rates in effect for the periods in which the differences are expected to reverse. Deferred tax assets are subject to management’s judgment based upon available evidence that future realizations are “more likely than not.” If management determines that the Corporation is not more likely than not, to realize some or all of the net deferred tax asset in the future, a charge to income tax expense may be required to reduce the value of the net deferred tax asset to the expected realizable value. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Penalties are recorded in noninterest expense in the year they are assessed and paid and are treated as a non-deductible expense for tax purposes. Interest is recorded in noninterest expense in the year it is assessed and paid and is treated as a deductible expense for tax purposes.

Retirement Plans and Other Postretirement Benefits

Substantially all employees who were hired before December 8, 2009 are covered by a noncontributory retirement plan. Effective December 31, 2009, the benefits under the noncontributory retirement plan, in its current form, were frozen and the plan was amended and converted to a cash balance plan, with participants not losing any pension benefits already earned in the plan. Prior to the cash balance plan conversion effective December 31, 2009, the plan provided benefits based on a formula of each participant’s final average pay. Future benefits under the cash balance plan accrue by crediting participants annually with an amount equal to a percentage of earnings in that year based on years of credited service as defined in the plan. Employees hired on or after December 8, 2009 are no longer eligible to participate in the noncontributory retirement plan. The Corporation also provides supplemental executive retirement benefits, a portion of which is in excess of limits imposed on qualified plans by federal tax law. These plans are non-qualified benefit plans. The Corporation provides certain postretirement healthcare and life insurance benefits for retired employees. The Corporation’s measurement date for plan assets and obligation is fiscal year-end. The Corporation recognizes on its consolidated balance sheet the funded status of its defined pension plans and changes in the funded status of the plan in the year in which the changes occur. An under-funded position would create a liability and an over-funded position would create an asset, with a correlating deferred tax asset or liability. The net impact would be an adjustment to equity as accumulated other comprehensive income (loss). The Corporation recognizes as a component of other comprehensive income (loss), net of tax, the actuarial gains and losses and the prior service costs and credits that arise during the period.



The Corporation sponsors a 401(k) deferred salary savings plan, which is a qualified defined contribution plan, and which covers all employees of the Corporation and its subsidiaries, and provides that the Corporation make matching contributions as defined by the plan.

The Corporation sponsors a Supplemental Non-Qualified Pension Plan (SNQPP) which was established in 1981 for employees who have served for several years, with ability and distinction, in one of the primary policy-making senior level positions, with the understanding that the future growth and continued success of the Corporation’s business may well reflect the continued services to be rendered by these employees and the Corporation’s desire to be reasonably assured that these employees will continue to serve and realizing that if these employees would enter into competition with the Corporation, it would suffer severe financial loss. The SNQPP was established prior to the existence of a 401(k) deferred salary savings, employee stock purchase and long-term incentive plans and therefore is not actively offered to new participants. These non-qualified plans are accounted for under guidance for deferred compensation arrangements.

Stock-Based Compensation

The fair value of share based awards is recognized as compensation expense over the vesting period based on the grant-date fair value of the awards. The Corporation uses the Black-Scholes Model to estimate the fair value of each option on the date of grant. The Black-Scholes Model estimates the fair value of employee stock options using a pricing model which takes into consideration the exercise price of the option, the expected life of the option, the current market price and its expected volatility, the expected dividends on the stock and the current risk-free interest rate for the expected life of the option. The Corporation grants stock options to employees with an exercise price equal to the fair value of the shares at the date of grant. The Corporation grants both fixed and variable (performance-based) restricted stock. The performance-based restricted stock awards vest based upon the Corporation’s performance against selected peers with respect to certain financial measures over a three-year period. The fair value of fixed restricted stock is equivalent to the fair value on the date of grant and is amortized over the vesting period. The fair value of the performance-based restricted stock is equivalent to the fair value on the date of grant and is amortized over the vesting period adjusted for a probability factor of achieving the performance goals.

Dividend Reinvestment and Employee Stock Purchase Plans

The Univest Dividend Reinvestment Plan allows for the issuance of 1,968,750 shares of common stock. During 2013 and 2012, 95,639 and 103,807 shares, respectively, were issued under the dividend reinvestment plan, with 635,103 shares available for future purchase at December 31, 2013.

The 1996 Employee Stock Purchase Plan allows for the issuance of 984,375 shares of common stock. Employees may elect to make contributions to the plan in an aggregate amount not less than 2% or more than 10% of such employee’s total compensation. These contributions are then used to purchase stock during an offering period determined by the Corporation’s Employee Stock Purchase Plan Committee. The purchase price of the stock is based solely on the market price of the shares at the date of purchase. Compensation expense is recognized if the discount is greater than 5% of the fair value. During 2013 and 2012, 20,195 and 20,933 shares, respectively, were issued under the employee stock purchase plan, with 755,895 shares available for future purchase at December 31, 2013.

Marketing and Advertising Costs

The Corporation’s accounting policy is to expense marketing and advertising costs as incurred, when the advertisement first takes place, or over the expected useful life of the related asset, as would be the case with billboards.

Statement of Cash Flows

The Corporation has defined those items included in the caption “Cash and due from banks” as cash and cash equivalents.



Trust Assets

Assets held by the Corporation in a fiduciary or agency capacity for its customers are not included in the consolidated financial statements since such items are not assets of the Corporation.

Earnings per Share

Basic earnings per share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if options on common shares had been exercised, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Corporation relate solely to outstanding stock options, and are determined using the treasury stock method. The effects of options to issue common stock are excluded from the computation of diluted earnings per share in periods in which the effect would be antidilutive.

Variable Interest Entities

Variable interest entities (VIE’s) are certain legal entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. A company must consolidate a VIE if the company has a variable interest or interests that provide the corporation with a controlling financial interest in the VIE which includes the power to direct the activities of a VIE that most significantly impact the VIE’S economic performance, the obligation to absorb expected losses of the VIE that could potentially be significant to the VIE and the right to receive expected benefits of the VIE that could potentially be significant to the VIE.

The accounting standards related to Subsidiary Trusts, as interpreted by the SEC, disallow consolidation of Subsidiary Trusts in the financial statements of the Corporation. As a result, securities that were issued by the trusts (Trust Preferred Securities) are not included on the Corporation’s consolidated balance sheets. The junior subordinated debentures issued by the Parent Company to the Subsidiary Trusts, which have the same total balance and rate as the combined equity securities and trust preferred securities issued by the Subsidiary Trusts are included in the Corporation’s consolidated balance sheets. The trust preferred securities were redeemed with a settlement date of July 8, 2013.

Recent Accounting Pronouncements

In July 2013, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU) which requires entities to present an unrecognized tax benefit or a portion of an unrecognized tax benefit for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, in the financial statements as a reduction to a deferred tax asset with some specified exceptions. 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, 2013, or January 1, 2014 for the Corporation. The adoption of this ASU will not have any impact on the Corporation’s financial statements.

In February 2013, the FASB issued an ASU to improve the transparency of reporting reclassifications out of accumulated other comprehensive income. The guidance requires entities to present, either on the face of the statement where net income is presented or in a single footnote, significant amounts that are required under U.S. GAAP to be reclassified to net income in their entirety. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to provide a cross-reference to other required U.S. GAAP disclosures. The amendment is effective for reporting periods beginning after December 15, 2012, or January 1, 2013 for the Corporation. The application of the provisions of this standard did not have a material impact on the Corporation’s financial statements although it resulted in additional disclosures which are included in Note 15, “Accumulated Other Comprehensive (Loss) Income.”

In December 2011, the FASB issued an ASU regarding disclosures about offsetting assets and liabilities. The scope of this accounting guidance was further clarified by an ASU issued by the FASB in January 2013. This guidance affects entities that have financial instruments and derivative instruments that are either (1) offset in accordance with U.S. GAAP or (2) subject to an enforceable master netting arrangement or similar agreement. This information will enable users of an entity’s financial statements to evaluate the effect or potential effect of netting arrangements on an entity’s financial position, including the effect or potential effect of rights of setoff associated with certain financial instruments and derivative instruments within the scope of this guidance. The guidance is effective for annual reporting periods beginning on or after January 1, 2013. The provisions of this guidance did not have any impact on the Corporation’s financial statements.

	Note 3. Acquisitions

	Girard Partners, Ltd.

	On December 19, 2013, the Corporation entered into an agreement to acquire Girard Partners, Ltd., a registered investment advisory firm with more than $500 million in assets under management. The Corporation completed the acquisition on January 27, 2014. With the acquisition, the Corporation will increase its assets under management to $3.0 billion and expand its advisory capabilities.

	The Corporation paid $5.6 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 $5.6 million in other liabilities. The potential cash payments that could result from the contingent consideration arrangement range from $0 to a maximum of $14.4 million cumulative over the next five years. As a result of the Girard Partners, Ltd. acquisition, the Corporation recorded goodwill of $6.9 million (inclusive of the contingent consideration) and customer related intangibles of $4.5 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.

	John T. Fretz Insurance Agency, Inc.

	On May 1, 2013, the Corporation and its insurance subsidiary, Univest Insurance, Inc., completed the acquisition of John T. Fretz Insurance Agency, Inc., a full-service property and casualty insurance agency providing solutions to both personal and commercial clients. The acquisition expands the Corporation’s insurance business and increases its market share in its core market.

	The Corporation paid $2.2 million in cash at closing with additional contingent consideration to be paid in annual installments over the three-year period ending April 30, 2016 based on the achievement of certain levels of revenue. At the acquisition date, the Corporation recorded the estimated fair value of the contingent consideration of $454 thousand in other liabilities. The potential cash payments that could result from the contingent consideration arrangement range from $0 to a maximum of $930 thousand cumulative over the next three years. As a result of the John T. Fretz Insurance Agency, Inc. acquisition, the Corporation recorded goodwill of $1.3 million (inclusive of the contingent consideration) and customer related intangibles of $1.3 million. The goodwill is expected to be deductible for tax purposes. The customer related intangibles are being amortized over seven years using the sum-of-the-years-digits amortization method.

	Javers Group

	On May 31, 2012, the Corporation and its insurance subsidiary, Univest Insurance, Inc., completed the acquisition of the Javers Group, a full-service employee benefits agency that specializes in comprehensive human resource management, payroll and administrative services to businesses with 50 to 1,000 employees. The acquisition expanded the Corporation’s insurance and employee benefits business and further diversified its solutions to include human resource consulting services and technology.



	The Corporation paid $3.2 million in cash at closing with additional contingent consideration to be paid in annual installments over the three-year period ending June 30, 2015 based on the achievement of certain levels of revenue. At the acquisition date, the Corporation recorded the estimated fair value of the contingent consideration of $842 thousand in other liabilities. 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. While the acquisition remains accretive, 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 December 31, 2013, 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. As a result of the Javers Group acquisition, the Corporation recorded goodwill of $3.1 million (inclusive of the contingent consideration) and customer related intangibles of $989 thousand. The goodwill is expected to be deductible for tax purposes. The customer related intangibles are being amortized over eight years using the sum-of-the-years-digits amortization method.

	The estimated fair value of the contingent consideration liability related to acquisitions was calculated using a discounted cash flow model of future contingent payments based on projected revenue related to the acquired business. The 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 estimated future contingent payments based on projected revenue of the acquired business affecting the contingent consideration liability is recorded through noninterest expense. The acquisitions were accounted for in accordance with accounting standards for business combinations.

The Corporation realized other-than-temporary impairment charges of $0 thousand and $13 thousand, respectively, to noninterest income on its equity portfolio during the years ended December 31, 2013 and 2012. As such, in 2012, the Corporation determined that it was probable that the fair value of certain equity securities would not recover to the Corporation’s cost basis within a reasonable period of time due to a decline in the financial stability of the underlying companies.
At December 31, 2013 and 2012, there were no investments in any single non-federal issuer representing more than 10% of shareholders’ equity.

The following table shows the fair value of securities that were in an unrealized loss position at December 31, 2013 and 2012 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 December 31, 2013 and 2012.
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

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, as well as the 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 by 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. At December 31, 2013, impaired loans included other accruing impaired loans of $27.5 million. At December 31, 2013, specific reserves of $1.6 million were established for three borrower relationships with principal balances totaling $2.6 million on other accruing impaired loans.

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 years ended December 31, 2013 and 2012:

	Note 7. Goodwill and Other Intangible Assets
	The Corporation has customer-related intangibles and mortgage servicing rights, which are not deemed to have an indefinite life and therefore will continue to be amortized over their useful life using the present value of projected cash flows. The amortization of intangible assets for the years ended December 31, 2013, 2012 and 2011 was $2.3 million, $2.4 million and $1.6 million, respectively. In 2013, 2012 and 2011, impairment on customer-related intangibles was recognized in other noninterest expense in the amount of $83 thousand, $31 thousand and $11 thousand, respectively. The Corporation also has goodwill with a net carrying amount of $57.5 million at December 31, 2013, which is deemed to be an indefinite intangible asset and is not amortized. The Corporation recorded additional goodwill of $1.3 million and customer related intangibles of $1.3 million related to the John T. Fretz Insurance Agency, Inc. acquisition on May 1, 2013. The Corporation recorded additional goodwill of $3.1 million and customer related intangibles of $989 thousand related to the Javers Group acquisition on May 31, 2012.
	The Corporation completed an annual impairment test for goodwill and other intangibles during the fourth quarter of 2013. There was no goodwill impairment and no material impairment of identifiable intangibles recorded during 2011 through 2013. There can be no assurance that future impairment assessments or tests will not result in a charge to earnings.
	Changes in the carrying amount of the Corporation’s goodwill for the years ended December 31, 2013 and 2012 were as follows:

	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 and $4.2 million at December 31, 2013 and 2012, respectively. The fair value of mortgage servicing rights was determined using discount rates ranging from 5.0% to 10.0% at December 31, 2013 and 2012.

	At December 31, 2013 and 2012, the Bank held $3.3 million in Federal Reserve Bank stock as required by the Federal Reserve Bank. The Bank is a member of the FHLB, and as such, is required to hold FHLB stock as a condition of membership as determined by the FHLB. The Bank is required to hold additional stock in the FHLB in relation to the level of outstanding borrowings. The Bank held FHLB stock of $3.2 million and $4.1 million at December 31, 2013 and 2012, respectively. Additionally, the FHLB might require its members to increase its capital stock requirement. Changes in the credit ratings of the U.S. government and federal agencies, including the FHLB, could increase the borrowing costs of the FHLB and possibly have a negative impact on its operations and long-term performance. It is possible this could have an adverse effect on the value of the Corporation’s investment in the FHLB stock. The Corporation determined there was no other-than-temporary impairment of its investment in FHLB stock at December 31, 2013. Therefore, at December 31, 2013, the FHLB stock is recorded at cost.

	During the years ended December 31, 2013 and 2012, the Corporation recorded excess tax benefits resulting from the exercise of employee stock options and restricted stock of $1 thousand and $0 thousand respectively, to additional paid-in capital.

	At December 31, 2013, the Corporation had no material unrecognized tax benefits, accrued interest or penalties. Penalties are recorded in noninterest expense in the year they are assessed and are treated as a non-deductible expense for tax purposes. Interest is recorded in noninterest expense in the year it is assessed and is treated as a deductible expense for tax purposes. The Corporation’s tax years 2010 through 2012 remain subject to federal examination as well as examination by state taxing jurisdictions.
	Deferred income taxes reflect the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amount used for income tax purposes. Deferred state taxes are combined with federal deferred taxes (net of the impact of deferred state tax on the deferred federal tax) and are shown in the table below by major category of deferred income or expense. The Corporation has a state net operating loss carry-forward of $24.6 million which will begin to expire after December 31, 2018 if not utilized. A valuation allowance at December 31, 2013 and 2012 was attributable to deferred tax assets generated in certain state jurisdictions for which management believes it is more likely than not that such deferred tax assets will not be realized. Additionally, deferred tax assets of $28 thousand and $78 thousand were reversed and recorded to additional paid-in capital during the years ended December 31, 2013 and 2012, respectively, as a result of unrecognizable restricted stock and non-qualified stock option expense.
	The assets and liabilities giving rise to the Corporation’s deferred tax assets and liabilities are as follows:

	Note 10. Retirement Plans and Other Postretirement Benefits
	Substantially all employees who were hired before December 8, 2009 are covered by a noncontributory retirement plan. Employees hired on or after December 8, 2009 are not eligible to participate in the noncontributory retirement plan. The Corporation also provides supplemental executive retirement benefits, a portion of which is in excess of limits imposed on qualified plans by federal tax law. These plans are non-qualified benefit plans. Information on these plans are aggregated and reported under “Retirement Plans” within this footnote.
	The Corporation also provides certain postretirement healthcare and life insurance benefits for retired employees. Information on these benefits is reported under “Other Postretirement Benefits” within this footnote.

	The Corporation sponsors a 401(k) deferred salary savings plan, which is a qualified defined contribution plan, and which covers all employees of the Corporation and its subsidiaries, and provides that the Corporation makes matching contributions as defined by the plan. Expense recorded by the Corporation for the 401(k) deferred salary savings plan for the years ended December 31, 2013, 2012 and 2011 was $765 thousand, $667 thousand, and $639 thousand, respectively.
	The Corporation sponsors a Supplemental Non-Qualified Pension Plan (SNQPP) which was established in 1981 prior to the existence of a 401(k) deferred salary savings, employee stock purchase and long-term incentive plans and therefore is not actively offered to new participants. Expense recorded by the Corporation for the SNQPP for the years ended December 31, 2013 and 2012 was $661 thousand and $531 thousand, respectively. The expense for 2013 was estimated using a weighted-average discount rate of 3.59%. Expense recorded by the Corporation for the SNQPP for the year ended December 31, 2011 of $463 thousand was more than offset by a reversal in the accrual of $467 thousand related to the passing of one of the participants.

The discount rate was determined utilizing the Citigroup Pension Discount Curve. Historical investment returns is the basis used to determine the overall expected long-term rate of return on assets. For 2013, the weighted average expected long-term rate of return on plan assets used to determine the net benefit cost was changed to 7.5% from 8.0%. The rate was changed during 2013 based on historical returns and future expectations of long-term asset returns.

Total			100	%			100	%

Plan assets include marketable equity securities, corporate and government debt securities, and certificates of deposit. The investment strategy is to keep a 60%-equity-to-40%-fixed-income mix to achieve the overall expected long-term rate of return of 7.5%. Equity securities do not include any common stock of the Corporation.
The major categories of assets in the Corporation’s pension plan at year-end are presented in the following table. Assets are segregated by the level of the valuation inputs within the fair value hierarchy described in Note 18, “Fair Value Disclosures.”

Mutual fund investments in U.S. large cap funds are comprised primarily of common stock funds which are diversified amongst various industries including basic materials (oil, gas, and other), financial services, healthcare, technology and other industries with some foreign exposure in the companies’ markets. The primary objective is long-term capital appreciation and a secondary objective of current income. Mutual fund investments in U.S. mid cap and small cap funds are comprised mainly of growth and value equity funds with some foreign exposure in the companies’ markets. Mutual fund investments in international funds consist mainly of equity funds that invest in diverse companies mostly based in Europe and the Pacific Basin with the primary objective to provide long-term growth of capital and a secondary objective of current income. Mutual fund investments in income funds are comprised of short-term and intermediate-term bond funds. Corporate bonds are fixed income investment grade bonds of primarily U.S. issuers from diverse industries. Other fixed-income investments include U.S. government agency securities and bank certificates of deposits. The fixed income investments have varying maturities ranging from one to ten years with the objective to maximize investment return while preserving investment principal. Short-term investments are comprised of an interest-bearing money market deposit account with the Bank.

Stock-Based Incentive Plan	'
	Note 11. Stock-Based Incentive Plan
	The Corporation adopted the shareholder approved 2013 Long-Term Incentive Plan to replace the 2003 Long-Term Incentive Plan which expired during April 2013. The 544,517 unissued common shares under the 2003 Long-Term Incentive Plan expired and are no longer available for future grant options or share awards. Under the 2013 Long-Term Incentive Plan, the Corporation may grant options and share awards to employees up to 2,000,000 shares of common stock. The plan provides for the issuance of options to purchase common shares at prices not less than 100 percent of the fair market value on the date of option grant and have a contractual term of ten years; and for restricted stock awards valued at not less than 100 percent of the fair market value at the date of award grant. For the majority of options issued, after two years, 33.3 percent of the optioned shares become exercisable in each of the following three years and remain exercisable for a period not exceeding ten years from the date of grant. For the majority of the restricted stock awards, the restriction lapses over a three-year period at 33.3 percent per year. There were 2,000,000 share awards available for future grants at December 31, 2013 under the plan. At December 31, 2013, there were 612,050 options to purchase common stock and 185,423 unvested restricted stock awards outstanding under the plan.
	The following is a summary of the status of options under the Corporation’s long-term incentive plan:

	Exercisable at December 31, 2013			343,391				21.85				3.7			142

	There were no stock options exercised during 2011 through 2013. The Corporation has a stock-for-stock-option exchange (or cashless exercise) program in place, whereby optionees can exchange the value of the spread of in-the-money vested options for Corporation stock having an equivalent value. This broker-assisted exchange allows the optionees to exercise their vested options on a net basis without having to pay the exercise price or related expenses in cash. However, it will result in the optionees acquiring fewer shares than the number of options exercised.
	The Corporation’s estimate of the fair value of a stock option is based on expectations derived from historical experience and may not necessarily equate to its market value when fully vested. The life of the option is based on historical factors which include the contractual term, vesting period, exercise behavior and employee turnover. The risk-free rate for periods within the expected term of the option is based on the U.S. Treasury strip rate in effect at the time of grant. Expected volatility is based on the historical volatility of the Corporation’s stock over the expected life of the grant. The Corporation uses a straight-line accrual method to recognize stock-based compensation expense over the time-period it expects the options to vest.

	The Corporation recognizes compensation expense for stock options over the requisite service period based on the grant-date fair value of those awards expected to ultimately vest. Forfeitures are estimated on the date of grant and revised if actual or expected forfeiture activity differs materially from original estimates. The following aggregated assumptions were used to estimate the fair value of options granted for the periods indicated:


			For the Years Ended December 31,

	The Corporation, through the Bank, has short-term and long-term credit facilities with the FHLB with a maximum borrowing capacity of approximately $484.1 million. Advances from the FHLB are collateralized by a blanket floating lien on all first mortgage loans of the Bank, FHLB capital stock owned by the Bank and any funds on deposit with the FHLB. At December 31, 2013 and 2012, there were no outstanding borrowings with the FHLB. At December 31, 2013 and 2012, the Bank had outstanding short-term letters of credit with the FHLB totaling $35.0 million and $32.0 million, respectively, which were utilized to collateralize public funds deposits. The maximum borrowing capacity changes as a function of the Bank’s qualifying collateral assets as well as the FHLB’s internal credit rating of the bank and the amount of funds received may be reduced by additional required purchases of FHLB stock.
	On May 14, 2013, the Corporation submitted a redemption notice to the trustee to redeem all of the outstanding capital securities issued by Univest Capital Trust I (Trust Preferred Securities), pursuant to the optional redemption provisions provided in the documents governing the Trust Preferred Securities. The Trust Preferred Securities had an aggregate principal balance of $20.0 million with an interest rate of three-month U.S. London Interbank Borrowing Rate (LIBOR) plus 3.05% per annum and a maturity date of October 7, 2033. The Trust Preferred Securities had a liquidation amount of $1,000 per trust preferred security plus accrued and unpaid distributions to the redemption date of July 7, 2013 and a settlement date Monday, July 8, 2013. The redemption also included $619 thousand in common securities issued by Univest Capital Trust I and related to the Trust Preferred Securities. Following the redemption, the Corporation’s capital levels remained well in excess of the regulatory minimum for well capitalized status.
	This redemption was consistent with the capital plan the Corporation submitted to the Federal Reserve and was funded from the Corporation’s existing cash. The Trust Preferred Securities were hedged and the Corporation recognized a loss in May 2013 on the termination of the associated interest rate swap of $1.9 million. The interest rate swap had a maturity date of January 7, 2019.
	The Bank maintains federal fund credit lines with several correspondent banks totaling $82.0 million at December 31, 2013 and 2012. There was no outstanding balance at December 31, 2013 or 2012. Future availability under these lines is subject to the prerogatives of the granting banks and may be withdrawn at will.

	The Corporation, through the Bank, has an available line of credit at the Federal Reserve Bank of Philadelphia, the amount of which is dependent upon the balance of loans and securities pledged as collateral. At December 31, 2013 and 2012, the Corporation had no outstanding borrowings from this line.

Commitments And Contingencies Disclosure [Abstract]	'
Commitments and Contingencies	'
	Note 16. Commitments and Contingencies
	Loan commitments are made to accommodate the financial needs of the Bank’s customers. The Bank offers commercial, mortgage, and consumer credit products to its customers in the normal course of business, which are detailed in Note 5. These products represent a diversified credit portfolio and are generally issued to borrowers within the Bank’s locations in Southeastern Pennsylvania. The ability of the customers to repay their credit is, to some extent, dependent upon the economy in the Bank’s market areas. Collateral is obtained based on management’s credit assessment of the customer.
	Standby letters of credit commit the Bank to make payments on behalf of customers when certain specified future events occur. They primarily are issued to support commercial paper, medium and long-term notes and debentures, including industrial revenue obligations. The approximate term is usually one year but some can be up to five years. Historically, substantially all standby letters of credit expire unfunded. If funded, the majority of the letters of credit carry current market interest rates if converted to loans. Because letters of credit are generally un-assignable by either the Bank or the borrower, they only have value to the Bank and the borrower. The carrying amount is recorded as unamortized deferred fees and the exposure is considered in the reserve for credit risk. At December 31, 2013, the maximum potential amount of future payments under letters of credit is $42.3 million. The current carrying amount of the contingent obligation is $420 thousand. This arrangement has credit risk essentially the same as that involved in extending loans to customers and is subject to the Bank’s normal credit policies. Collateral is obtained based on management’s credit assessment of the customer.
	The Bank maintains a reserve in other liabilities for estimated losses associated with sold mortgages that may be repurchased. At December 31, 2013, the reserve for sold mortgages was $260 thousand.
	The Corporation entered into risk participation agreements (RPAs) as a guarantor to other financial institutions, in order to mitigate those institutions’ credit risk associated with interest rate swaps with third parties. The RPA stipulates that, in the event of default by the third party on the interest rate swap, the Corporation will reimburse a portion of the loss borne by the financial institution. The third parties usually have other borrowing relationships with the Corporation. The Corporation monitors overall borrower collateral and performance, and at the end of December 31, 2013, believes sufficient collateral is available to cover potential swap losses. The Corporation pledges cash or securities to cover a portion of the negative fair value of the RPAs, as measured by the participant financial institution. The terms of the RPAs, which correspond to the terms of the underlying swaps, range from 5 to 13 years. At December 31, 2013, the notional amount of the RPAs was $22.9 million, with a negative fair value of $1.3 million, of which $690 thousand was pledged to the participant financial institutions as collateral. The maximum potential future payment guaranteed by the Corporation cannot be readily estimated, but is dependent upon the fair value of the interest rate swaps at the time of default. If an event of default on all contracts had occurred at December 31, 2013, the Corporation would have been required to make payments of approximately $1.3 million. The RPA requires the Corporation to reimburse the institution in proportion to the pro rata share of the third party transactions, in the event the third party fails to make a payment to the institution. In exchange, the Corporation receives an agreed-upon fee from the institution for taking this risk. The fee is paid upfront to the Corporation and the Corporation recognizes the fee over the maturity of the loan. The fair value of the guarantee was $80 thousand at December 31, 2013.
	Based on consultation with the Corporation’s legal counsel, management is not aware of any litigation that would have a material adverse effect on the Corporation’s consolidated balance sheet or statement of income. There are no proceedings pending other than the ordinary routine litigation incident to the business of the Corporation. In addition, there are no material proceedings pending or known to be threatened or contemplated against the Corporation or the Bank by government authorities.

	Note 17. 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 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.
	On December 23, 2008, the Corporation entered into a cash flow hedge with a notional amount of $20.0 million that had the effect of converting the variable rates on Trust Preferred Securities to a fixed rate. Under the terms of the swap agreement, the Corporation paid a fixed rate of 2.65% and received a floating rate based on the three-month LIBOR with a maturity date of January 7, 2019. During May 2013, the Corporation terminated the swap in conjunction with the submission of a redemption notice to the trustee to redeem the Trust Preferred Securities on July 7, 2013, pursuant to the optional redemption provisions provided in the documents governing the Trust Preferred Securities. See Note 13, “Borrowings” for additional information.

Fair Value Disclosures [Abstract]	'
Fair Value Disclosures	'
	Note 18. 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 on 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, 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 year 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, and corporate, 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 December 31, 2013.
	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 non-interest 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 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. While the acquisition remains accretive, 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 December 31, 2013, 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.
	For the John T. Fretz Insurance Agency, Inc. 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.

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 sheets 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 December 31, 2013 and 2012.
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 December 31, 2013, impaired loans held for investment had a carrying amount of $58.3 million with a valuation allowance of $3.0 million. At December 31, 2012, impaired loans held for investment had a carrying amount of $45.2 million with a valuation allowance of $208 thousand.
Mortgage servicing rights: The Corporation estimates the fair value of mortgage servicing rights using discounted cash flow models that calculate the present value of estimated future net servicing income. The model uses readily available prepayment speed assumptions for the 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 on a quarterly basis for impairment and the mortgage servicing rights are carried at the lower of amortized cost or estimated fair value. At December 31, 2013, mortgage servicing rights had a carrying amount of $5.8 million with a valuation allowance of $250 thousand. At December 31, 2012, mortgage servicing rights had a carrying amount of $4.6 million with a valuation allowance of $497 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. The Corporation completed an annual impairment test for goodwill and other intangibles during the fourth quarter of 2013. There was no goodwill impairment and no material impairment of identifiable intangibles recorded.
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 properly, less estimated costs to sell. New appraisals are generally obtained at least 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.
Long-term borrowings: The fair values of the Corporation’s long-term borrowings are estimated using a discounted cash flow analysis based on current market rates for similar borrowings, and include components for credit risk, operating expense, and embedded prepayment options that are observable. Long-term borrowings 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.

	Note 19. Restructuring Charges
	During the first quarter of 2013, the Corporation implemented a company-wide restructuring plan which reduced staffing levels by 3.4% and included the announced closure and consolidation of its Silverdale financial service center, effective May 3, 2013, into the Hilltown and Perkasie locations. As a result, the Corporation recorded $539 thousand in restructuring charges during the first quarter of 2013, which consisted of $437 thousand in severance and $102 thousand in fixed asset retirement expenses. These charges are included in restructuring charges, a component of non-interest expense, within the consolidated statement of income. The restructuring involved strategic changes to ensure the Corporation is effectively managing costs, improving efficiencies and evolving the business to meet the need of all its stakeholders.
	A roll-forward of the accrued restructuring expense is as follows:

Banking And Thrift [Abstract]	'
Regulatory Matters	'
	Note 21. Regulatory Matters
	The Corporation and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Corporation’s and Bank’s financial statements. Capital adequacy guidelines, and additionally for the Bank prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weighting and other factors.

	Quantitative measures established by regulation to ensure capital adequacy require the Corporation and the Bank to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined).

	On May 14, 2013, the Corporation submitted a redemption notice to the trustee to redeem all of the outstanding capital securities issued by Univest Capital Trust I, with a redemption date of July 7, 2013. This is the primary reason that the Corporation’s regulatory capital ratios declined when comparing December 31, 2013 to December 31, 2012. Additionally, during the second quarter of 2013, the Bank’s subsidiary, Delview, Inc., called its preferred stock of $15.0 million, which qualified as Tier 1 Capital at the Bank as “Qualifying Noncontrolling (Minority) Interests in Consolidated Subsidiaries.” This is the primary reason that the Bank’s regulatory capital ratios declined when comparing December 31, 2013 to December 31, 2012.
	At December 31, 2013 and December 31, 2012, management believes that the Corporation and the Bank met all capital adequacy requirements to which they were subject. The Corporation, like other bank holding companies, currently is required to maintain Tier 1 Capital and Total Capital (the sum of Tier 1, Tier 2 and Tier 3 capital) equal to at least 4.0% and 8.0%, respectively, of its total risk-weighted assets (including various off-balance-sheet items, such as standby letters of credit). The Bank, like other depository institutions, is required to maintain similar capital levels under capital adequacy guidelines. For a depository institution to be considered “well capitalized” under the regulatory framework for prompt corrective action, its Tier 1 and Total Capital ratios must be at least 6.0% and 10.0% on a risk-adjusted basis, respectively. At December 31, 2013, the Bank is categorized as “well capitalized” under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank’s category.
	In July 2013, the federal bank regulatory agencies adopted final rules revising the agencies’ capital adequacy guidelines and prompt corrective action rules, designed to enhance such requirements and implement the revised standards of the Basel Committee on Banking Supervision, commonly referred to as Basel III. The July 2013 final rules generally implement higher minimum capital requirements, add a new common equity Tier 1 capital requirement, and establish criteria that instruments must meet to be considered common equity Tier 1 capital, additional Tier 1 capital or Tier 2 capital. The new minimum capital to risk-adjusted assets requirements are a common equity Tier 1 capital ratio of 4.5% (6.5% to be considered “well capitalized”) and a Tier 1 capital ratio of 6.0%, increased from 4.0% (and increased from 6.0% to 8.0% to be considered “well capitalized”); the total capital ratio remains at 8.0% under the new rules (10.0% to be considered “well capitalized”). Under the new rules, in order to avoid limitations on capital distributions (including dividend payments and certain discretionary bonus payments to executive officers), a banking organization must hold a capital conservation buffer comprised of common equity Tier 1 capital above its minimum risk-based capital requirements in an amount greater than 2.5% of total risk-weighted assets. The final rules permit institutions, other than certain large institutions, to elect to continue to treat certain components of accumulated other comprehensive income as permitted under the current general risk-based capital rules, and not reflect unrealized gains and losses on available-for-sale securities in common equity Tier 1 calculations. The new minimum capital requirements are effective on January 1, 2015. The capital conservation buffer requirements phase in over a three-year period beginning January 1, 2016. The Corporation and the Bank will continue to analyze these new rules and their effects on the business, operations and capital levels of the Corporation and the Bank.
	Dividend and Other Restrictions
	The primary source of the Corporation’s dividends paid to its shareholders is from the earnings of its subsidiaries paid to the Corporation in the form of dividends.
	The approval of the Federal Reserve Board of Governors is required for a state bank member in the Federal Reserve system to pay dividends if the total of all dividends declared in any calendar year exceeds the Bank’s net profits (as defined) for that year combined with its retained net profits for the preceding two calendar years. Under this formula, the Bank can declare dividends in 2014 without approval of the Federal Reserve Board of Governors of approximately $3.8 million plus an additional amount equal to the Bank’s net profits for 2014 up to the date of any such dividend declaration.
	Federal Reserve Board policy applicable to the holding company also provides that, as a general matter, a bank holding company should inform the Federal Reserve and should eliminate, defer or significantly reduce the holding company’s dividends if the holding company’s net income for the preceding four quarters, net of dividends paid during the period, is not sufficient to fully fund the dividends, the holding company’s prospective rate of earnings retention is inconsistent with capital needs and overall current and prospective financial condition, or the holding company will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios. Federal Reserve Board policy also provides that a bank holding company should inform the Federal Reserve reasonably in advance of declaring or paying a dividend that exceeds earnings for the period or that could result in a material adverse change to the organization’s capital structure.
	The Federal Reserve Act requires that extension of credit by the Bank to certain affiliates, including the Corporation (parent), be secured by readily marketable securities, that extension of credit to any one affiliate be limited to 10% of the Bank’s capital and surplus (as defined), and that extensions of credit to all such affiliates be limited to 20% of the Bank’s capital and surplus.

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2013
Accounting Policies [Abstract]	'
Organization	'
	Organization
	Univest Corporation of Pennsylvania (the Corporation) through its wholly owned subsidiary, Univest Bank and Trust Co. (the Bank), is engaged in domestic commercial and retail banking services and provides a full range of community banking and trust services to its customers. The Bank wholly owns Univest Capital, Inc., which provides lease financing, and Delview, Inc., who through its subsidiaries, Univest Investments, Inc. and Univest Insurance, Inc., provides financial planning, investment management, insurance products and brokerage services. Univest Investments, Univest Insurance and Univest Capital were formed to enhance the traditional banking and trust services provided by the Bank. The Corporation’s former subsidiary, Univest Delaware, Inc., was dissolved during 2013. Univest Investments, Univest Insurance and Univest Capital do not currently meet the quantitative and qualitative thresholds for separate disclosure provided as a business segment. Therefore, the Corporation currently has one reportable segment, “Community Banking,” and strategically this is how the Corporation operates and has positioned itself in the marketplace. The Corporation’s activities are interrelated, each activity is dependent, and performance is assessed based on how each of these activities supports the others. Accordingly, significant operating decisions are based upon analysis of the Corporation as one Community Banking operating segment. The Bank serves Montgomery, Bucks, Chester and Lehigh counties of Pennsylvania through thirty-one banking offices and provides banking and trust services to the residents and employees of twelve retirement communities. Banking services are also available on-line at the Corporation’s website at www.univest.net.
Principles of Consolidation	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Corporation and its wholly owned subsidiary, the Bank. All significant intercompany balances and transactions have been eliminated in consolidation and certain prior period amounts have been reclassified to conform to current-year presentation.
Use of Estimates	'
	Use of Estimates
	The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include fair value measurement of investment securities available-for- sale and assessment for impairment of certain investment securities, reserve for loan and lease losses, valuation of goodwill and other intangible assets, mortgage servicing rights, deferred tax assets and liabilities, benefit plans and stock-based compensation expense.
Interest-earning Deposits with Other Banks	'
	Interest-earning Deposits with Other Banks
	Interest-earning deposits with other banks consist of deposit accounts with other financial institutions generally having maturities of three months or less.
Investment Securities	'
	Investment Securities
	Securities are classified as investment securities held-to-maturity and carried at amortized cost if management has the positive intent and ability to hold the securities to maturity. Securities purchased with the intention of recognizing short-term profits are placed in the trading account and are carried at fair value. The Corporation did not have any trading account securities at December 31, 2013 or 2012. Securities not classified as held-to-maturity or trading are designated securities available-for-sale and carried at fair value with unrealized gains and losses reflected in other comprehensive income, net of estimated income taxes. Realized gains and losses on the sale of investment securities are recognized using the specific identification method and are included in the consolidated statements of income. The amortization of premiums and accretion of discounts are included in interest income and calculated using the level yield method.

	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 credit portion of any loss on debt securities is recognized through earnings and the noncredit portion of any loss related to debt securities that the Corporation does not intend to sell, and it is more likely than not that the Corporation will not be required to sell the securities prior to recovery, is recognized in other comprehensive income, net of tax. The Corporation did not recognize any other-than-temporary impairment charges on debt securities during the years of 2011 through 2013.
	The Corporation evaluates its equity securities for other-than-temporary impairment and recognizes other-than-temporary impairment charges when it has determined that it is probable that the fair value of certain equity securities will not recover to the Corporation’s cost basis in the individual securities within a reasonable period of time due to a decline in the financial stability of the underlying companies. Management evaluates the near-term prospects of the issuers in relation to the severity and duration of the impairment. The Corporation has the intent and ability to hold these securities until recovery of the Corporation’s cost basis occurs.
Loans and Leases	'
	Loans and Leases
	Loans and leases are stated at the principal amount less net deferred fees and unearned discount. Interest income on commercial, consumer, and mortgage loans is recorded on the outstanding balance method, using actual interest rates applied to daily principal balances. Loan commitments are made to accommodate the financial needs of the customers. These commitments represent off-balance sheet items that are unfunded. Accrual of interest income on loans and leases ceases when collectability of interest and/or principal is questionable. If it is determined that the collection of interest previously accrued is uncertain, such accrual is reversed and charged to current earnings. Loans and leases are considered past due based upon failure to comply with contractual terms.
	A loan or lease is typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest, even though the loan or lease is currently performing. When a loan or lease, including an impaired loan or lease, is classified as nonaccrual, the accrual of interest on such a loan or lease is discontinued. A loan or lease may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan or lease is placed on nonaccrual status, unpaid interest credited to income in the current year is reversed. Interest received on nonaccrual loans and leases is either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. Loans and leases are usually restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. A loan or lease is considered impaired when, based on current information and events, it is probable that the Corporation will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the loan agreement. Interest on impaired loans and leases, which are not classified as nonaccrual, is recognized on the accrual basis.
Loan and Lease Fees	'
	Loan and Lease Fees
	Fees collected upon loan or lease origination and certain direct costs of originating loans and leases are deferred and recognized over the contractual lives of the related loans and leases as yield adjustments using the interest method. Upon prepayment or other disposition of the underlying loans and leases before their contractual maturities, any associated unearned fees or unamortized costs are recognized.
Reserve for Loan and Lease Losses	'

	Reserve for Loan and Lease Losses

	The reserve for loan and lease losses is maintained at a level that management believes is appropriate to absorb known and inherent losses in the loan and lease portfolio. Management’s methodology to determine the adequacy of and the provision to the reserve considers specific credit reviews, past loan and lease loss experience, current economic conditions and trends and the volume, growth, and composition of the loan portfolio.



	The reserve for loan and lease losses is determined through a monthly evaluation of reserve adequacy. This analysis takes into consideration the growth of the loan and lease portfolio, the status of past-due loans and leases, current economic conditions, various types of lending activity, policies, real estate and other loan commitments, and significant changes in charge-off activity. Impaired loans, including nonaccrual loans and leases, troubled debt restructured loans and other accruing impaired loans are evaluated individually. All other loans and leases are evaluated as pools. Based on historical loss experience and qualitative factors, loss factors are determined giving consideration to the areas noted in the first paragraph and applied to the pooled loan and lease categories to develop the general or allocated portion of the reserve. Loss factors are updated quarterly. Historical loss experience is comprised of losses aggregated over eight quarters. Management also reviews the activity within the reserve to determine what actions, if any, should be taken to address differences between estimated and actual losses. Any of the above factors may cause the provision to fluctuate.

	The reserve for loan and lease losses is based on management’s evaluation of the loan and lease portfolio under current economic conditions and such other factors, which deserve recognition in estimating loan and lease losses. This evaluation is inherently subjective, as it requires estimates including the amounts and timing of future cash flows expected to be received on impaired loans and leases that may be susceptible to significant change. Additions to the reserve arise from the provision for loan and lease losses charged to operations or from the recovery of amounts previously charged off. Loan and lease charge-offs reduce the reserve. Loans and leases are charged off when there has been permanent impairment or when in the opinion of management the full amount of the loan or lease will not be realized. Certain impaired loans are reported at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent, or for certain impaired loans, at the present value of expected future cash flows using the loan’s initial effective interest rate. For commercial impaired loans which are collateral dependent, the fair value of collateral is based on appraisals performed by qualified licensed appraisers hired by the Corporation less management’s estimated costs to sell. Appraisals are updated annually and obtained more frequently if changes in the property or market conditions warrant. Once an updated appraisal is received, if the fair value less estimated costs to sell is less than the carrying amount of the collateral dependent loan, a charge-off to the reserve for loan and lease losses is recorded for the difference.

	The reserve for loan and lease losses consists of an allocated reserve and an unallocated reserve. The allocated reserve is comprised of reserves established on specific loans and leases, and class reserves based on historical loan and lease loss experience, current trends, and management assessments. The unallocated reserve is based on both general economic conditions and other risk factors in the Corporation’s individual markets and portfolios.

	The specific reserve element is based on a regular analysis of impaired commercial and real estate loans. For these loans, the specific reserve established is based on a careful analysis of related collateral value, cash flow considerations and, if applicable, guarantor capacity.

	The class reserve element is determined by an internal loan and lease grading process in conjunction with associated allowance factors. The Corporation revises the class allowance factors whenever necessary in order to address improving or deteriorating credit quality trends or specific risks associated with a given loan or lease pool classification.

	The Corporation maintains an unallocated reserve to recognize the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and allocated losses in the portfolio. There are many factors considered such as the inherent delay in obtaining information regarding a customer’s financial condition or changes in their business condition, the judgmental nature of loan and lease evaluations, the delay in the interpretation of economic trends and the judgmental nature of collateral assessments. The Corporation also maintains a reserve in other liabilities for off-balance sheet credit exposures that currently are unfunded in categories with historical loss experience. In addition, the Bank’s primary examiner, as a regular part of their examination process, may require the Bank to increase the level of reserves.
Premises and Equipment	'
	Premises and Equipment
	Land is stated at cost, and premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method and charged to operating expenses over the estimated useful lives of the assets. The estimated useful life for new buildings constructed on land owned is forty years, and for new buildings constructed on leased land, is the lesser of forty years or the lease term including anticipated renewable terms. The useful life of purchased existing buildings is the estimated remaining useful life at the time of the purchase. Land improvements are considered to have estimated useful lives of fifteen years or the lease term including anticipated renewable terms. Furniture, fixtures and equipment have estimated useful lives ranging from three to ten years.
Goodwill and Other Intangible Assets	'
	Goodwill and Other Intangible Assets
	The Corporation accounts for its acquisitions using the purchase accounting method. Purchase accounting requires the total purchase price to be allocated to the estimated fair values of assets acquired and liabilities assumed, including certain intangible assets that must be recognized. Typically, this allocation results in the purchase price exceeding the fair value of net assets acquired, which is recorded as goodwill. Core deposit intangibles are a measure of the value of checking, money market and savings deposits acquired in business combinations accounted for under the purchase method. Core deposit intangibles and other identified intangibles with finite useful lives are amortized using the sum of the year’s digits over their estimated useful lives of up to fifteen years. Customer related intangibles are amortized over their estimated useful lives of five to twelve years. Covenants not to compete are amortized over their three to five-year contractual lives. The Corporation completes a goodwill analysis at least on an annual basis or more often if events and circumstances indicate that there may be impairment. The Corporation also completes an impairment test for other intangible assets on an annual basis or more often if events and circumstances indicate a possible impairment. There can be no assurance that future impairment analyses will not result in a charge to earnings.
	Mortgage servicing rights are recognized as separate assets when mortgage loans are sold and the servicing rights are retained. Capitalized mortgage servicing rights are reported in other intangible assets and are amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing period of the underlying mortgage loans. Mortgage servicing rights are evaluated for impairment, on a quarterly basis, based upon the fair value of the servicing rights as compared to amortized cost. The Corporation estimates the fair value of mortgage servicing rights using discounted cash flow models that calculate the present value of estimated future net servicing income. The model uses readily available prepayment speed assumptions for the current interest rates of the portfolios serviced. Mortgage servicing rights are carried at the lower of amortized cost or estimated fair value. Impairment is recognized through a valuation allowance, to the extent that fair value is less than the unamortized capitalized amount.
Bank Owned Life Insurance	'

	Bank Owned Life Insurance

	The Corporation carries bank owned life insurance (BOLI) at the net cash surrender value of the policies. Changes in the net cash surrender value of these policies are reflected in noninterest income. Proceeds from and purchases of bank owned life insurance are reflected in the statement of cash flows under investing activities. The Corporation recognizes a liability for the future death benefit for certain endorsement split-dollar life insurance arrangements that provide an employee with a death benefit in a postretirement/ termination period.
Other Real Estate Owned	'
	Other Real Estate Owned
	Other real estate owned represents properties acquired through customers’ loan defaults and is included in other assets. 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. Any write-down, at or prior to the dates the real estate is considered foreclosed, is charged to the allowance for loan losses. Subsequent write-downs and any gain or loss upon the sale of real estate owned is recorded in other noninterest income. Expenses incurred in connection with holding such assets are recorded in other noninterest expense.
Derivative Financial Instruments	'
	Derivative Financial Instruments
	The Corporation recognizes all derivative financial instruments on its balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through income. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative are either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings, or recognized in other comprehensive income until the underlying forecasted transaction is recognized in earnings. The ineffective portion of a derivative’s change in fair value is recognized in earnings immediately. To determine fair value, the Corporation uses third party pricing models that incorporate assumptions about market conditions and risks that are current at the reporting date.
	The Corporation may use interest-rate swap agreements to modify interest rate characteristics from variable to fixed or fixed to floating in order to reduce the impact of interest rate changes on future net interest income. The Corporation accounts for its interest-rate swap contracts in cash flow hedging relationships by establishing and documenting the effectiveness of the instrument in offsetting the change in cash flows of assets or liabilities that are being hedged. To determine effectiveness, the Corporation performs an analysis to identify if changes in fair value or cash flow of the derivative correlate to the equivalent changes in the forecasted interest receipts related to a specified hedged item. Recorded amounts related to interest-rate swaps are included in other assets or liabilities. The change in fair value of the ineffective part of the instrument would need to be charged to the statement of operations, potentially causing material fluctuations in reported earnings in the period of the change relative to comparable periods. In a fair value hedge, the fair values of the interest rate swap agreements and changes in the fair values of the hedged items are recorded in the Corporation’s consolidated balance sheet with the corresponding gain or loss being recognized in the consolidated statement of operations. The difference between changes in the fair values of interest rate swap agreements and the hedged items represents hedge ineffectiveness and is recorded in net interest income in the statement of operations. The Corporation performs an assessment, both at the inception of the hedge and quarterly thereafter, to determine whether these derivatives are highly effective in offsetting changes in the value of the hedged items.
	In connection with its mortgage banking activities, the Corporation enters into commitments to originate certain fixed-rate residential mortgage loans for customers, also referred to as interest rate locks. In addition, the Corporation enters into forward commitments for the future sale or purchase of mortgage loans to or from third-party investors to hedge the effect of changes in interest rates on the value of the interest rate locks. Forward loan sale commitments may also be in the form of commitments to sell individual mortgage loans at a fixed price at a future date. Both the interest rate locks and the forward loan sale commitments are accounted for as derivatives and carried at fair value, determined as the amount that would be necessary to settle each derivative financial instrument at the balance sheet date. Gross derivative assets and liabilities are recorded within other assets and other liabilities on the consolidated balance sheets, with changes in fair value during the period recorded within the net gain on mortgage banking activities on the consolidated statements of operations.
Federal Home Loan Bank Stock, Federal Reserve Bank Stock and Certain Other Investments without Readily Determinable Fair Values	'
	Federal Home Loan Bank Stock, Federal Reserve Bank Stock and Certain Other Investments without Readily Determinable Fair Values
	Federal Home Loan Bank stock, Federal Reserve Bank stock and certain other investments without readily determinable fair values are classified as other assets on the consolidated balance sheets. These investments are carried at cost and evaluated for impairment periodically or if events or circumstances indicate that there may be impairment.
Income Taxes	'
	Income Taxes
	There are two components of income tax expense: current and deferred. Current income tax expense approximates cash to be paid or refunded for taxes for the applicable period. Deferred income taxes are provided for temporary differences between amounts reported for financial statement and tax purposes. Deferred income taxes are computed using the asset and liability method, such that deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between financial reporting amounts and the tax basis of existing assets and liabilities based on currently enacted tax laws and tax rates in effect for the periods in which the differences are expected to reverse. Deferred tax assets are subject to management’s judgment based upon available evidence that future realizations are “more likely than not.” If management determines that the Corporation is not more likely than not, to realize some or all of the net deferred tax asset in the future, a charge to income tax expense may be required to reduce the value of the net deferred tax asset to the expected realizable value. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Penalties are recorded in noninterest expense in the year they are assessed and paid and are treated as a non-deductible expense for tax purposes. Interest is recorded in noninterest expense in the year it is assessed and paid and is treated as a deductible expense for tax purposes.
Retirement Plans and Other Postretirement Benefits	'

	Retirement Plans and Other Postretirement Benefits

	Substantially all employees who were hired before December 8, 2009 are covered by a noncontributory retirement plan. Effective December 31, 2009, the benefits under the noncontributory retirement plan, in its current form, were frozen and the plan was amended and converted to a cash balance plan, with participants not losing any pension benefits already earned in the plan. Prior to the cash balance plan conversion effective December 31, 2009, the plan provided benefits based on a formula of each participant’s final average pay. Future benefits under the cash balance plan accrue by crediting participants annually with an amount equal to a percentage of earnings in that year based on years of credited service as defined in the plan. Employees hired on or after December 8, 2009 are no longer eligible to participate in the noncontributory retirement plan. The Corporation also provides supplemental executive retirement benefits, a portion of which is in excess of limits imposed on qualified plans by federal tax law. These plans are non-qualified benefit plans. The Corporation provides certain postretirement healthcare and life insurance benefits for retired employees. The Corporation’s measurement date for plan assets and obligation is fiscal year-end. The Corporation recognizes on its consolidated balance sheet the funded status of its defined pension plans and changes in the funded status of the plan in the year in which the changes occur. An under-funded position would create a liability and an over-funded position would create an asset, with a correlating deferred tax asset or liability. The net impact would be an adjustment to equity as accumulated other comprehensive income (loss). The Corporation recognizes as a component of other comprehensive income (loss), net of tax, the actuarial gains and losses and the prior service costs and credits that arise during the period.



	The Corporation sponsors a 401(k) deferred salary savings plan, which is a qualified defined contribution plan, and which covers all employees of the Corporation and its subsidiaries, and provides that the Corporation make matching contributions as defined by the plan.

	The Corporation sponsors a Supplemental Non-Qualified Pension Plan (SNQPP) which was established in 1981 for employees who have served for several years, with ability and distinction, in one of the primary policy-making senior level positions, with the understanding that the future growth and continued success of the Corporation’s business may well reflect the continued services to be rendered by these employees and the Corporation’s desire to be reasonably assured that these employees will continue to serve and realizing that if these employees would enter into competition with the Corporation, it would suffer severe financial loss. The SNQPP was established prior to the existence of a 401(k) deferred salary savings, employee stock purchase and long-term incentive plans and therefore is not actively offered to new participants. These non-qualified plans are accounted for under guidance for deferred compensation arrangements.
Stock-Based Compensation	'

	Stock-Based Compensation

	The fair value of share based awards is recognized as compensation expense over the vesting period based on the grant-date fair value of the awards. The Corporation uses the Black-Scholes Model to estimate the fair value of each option on the date of grant. The Black-Scholes Model estimates the fair value of employee stock options using a pricing model which takes into consideration the exercise price of the option, the expected life of the option, the current market price and its expected volatility, the expected dividends on the stock and the current risk-free interest rate for the expected life of the option. The Corporation grants stock options to employees with an exercise price equal to the fair value of the shares at the date of grant. The Corporation grants both fixed and variable (performance-based) restricted stock. The performance-based restricted stock awards vest based upon the Corporation’s performance against selected peers with respect to certain financial measures over a three-year period. The fair value of fixed restricted stock is equivalent to the fair value on the date of grant and is amortized over the vesting period. The fair value of the performance-based restricted stock is equivalent to the fair value on the date of grant and is amortized over the vesting period adjusted for a probability factor of achieving the performance goals.
Dividend Reinvestment and Employee Stock Purchase Plans	'
	Dividend Reinvestment and Employee Stock Purchase Plans
	The Univest Dividend Reinvestment Plan allows for the issuance of 1,968,750 shares of common stock. During 2013 and 2012, 95,639 and 103,807 shares, respectively, were issued under the dividend reinvestment plan, with 635,103 shares available for future purchase at December 31, 2013.
	The 1996 Employee Stock Purchase Plan allows for the issuance of 984,375 shares of common stock. Employees may elect to make contributions to the plan in an aggregate amount not less than 2% or more than 10% of such employee’s total compensation. These contributions are then used to purchase stock during an offering period determined by the Corporation’s Employee Stock Purchase Plan Committee. The purchase price of the stock is based solely on the market price of the shares at the date of purchase. Compensation expense is recognized if the discount is greater than 5% of the fair value. During 2013 and 2012, 20,195 and 20,933 shares, respectively, were issued under the employee stock purchase plan, with 755,895 shares available for future purchase at December 31, 2013.
Marketing and Advertising Costs	'
	Marketing and Advertising Costs
	The Corporation’s accounting policy is to expense marketing and advertising costs as incurred, when the advertisement first takes place, or over the expected useful life of the related asset, as would be the case with billboards.
Statement of Cash Flows	'
	Statement of Cash Flows
	The Corporation has defined those items included in the caption “Cash and due from banks” as cash and cash equivalents.
Trust Assets	'
	Trust Assets
	Assets held by the Corporation in a fiduciary or agency capacity for its customers are not included in the consolidated financial statements since such items are not assets of the Corporation.
Earnings per Share	'
	Earnings per Share
	Basic earnings per share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if options on common shares had been exercised, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Corporation relate solely to outstanding stock options, and are determined using the treasury stock method. The effects of options to issue common stock are excluded from the computation of diluted earnings per share in periods in which the effect would be antidilutive.
Variable Interest Entities	'

	Variable Interest Entities

	Variable interest entities (VIE’s) are certain legal entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. A company must consolidate a VIE if the company has a variable interest or interests that provide the corporation with a controlling financial interest in the VIE which includes the power to direct the activities of a VIE that most significantly impact the VIE’S economic performance, the obligation to absorb expected losses of the VIE that could potentially be significant to the VIE and the right to receive expected benefits of the VIE that could potentially be significant to the VIE.

	The accounting standards related to Subsidiary Trusts, as interpreted by the SEC, disallow consolidation of Subsidiary Trusts in the financial statements of the Corporation. As a result, securities that were issued by the trusts (Trust Preferred Securities) are not included on the Corporation’s consolidated balance sheets. The junior subordinated debentures issued by the Parent Company to the Subsidiary Trusts, which have the same total balance and rate as the combined equity securities and trust preferred securities issued by the Subsidiary Trusts are included in the Corporation’s consolidated balance sheets. The trust preferred securities were redeemed with a settlement date of July 8, 2013.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU) which requires entities to present an unrecognized tax benefit or a portion of an unrecognized tax benefit for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, in the financial statements as a reduction to a deferred tax asset with some specified exceptions. 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, 2013, or January 1, 2014 for the Corporation. The adoption of this ASU will not have any impact on the Corporation’s financial statements.
	In February 2013, the FASB issued an ASU to improve the transparency of reporting reclassifications out of accumulated other comprehensive income. The guidance requires entities to present, either on the face of the statement where net income is presented or in a single footnote, significant amounts that are required under U.S. GAAP to be reclassified to net income in their entirety. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to provide a cross-reference to other required U.S. GAAP disclosures. The amendment is effective for reporting periods beginning after December 15, 2012, or January 1, 2013 for the Corporation. The application of the provisions of this standard did not have a material impact on the Corporation’s financial statements although it resulted in additional disclosures which are included in Note 15, “Accumulated Other Comprehensive (Loss) Income.”
	In December 2011, the FASB issued an ASU regarding disclosures about offsetting assets and liabilities. The scope of this accounting guidance was further clarified by an ASU issued by the FASB in January 2013. This guidance affects entities that have financial instruments and derivative instruments that are either (1) offset in accordance with U.S. GAAP or (2) subject to an enforceable master netting arrangement or similar agreement. This information will enable users of an entity’s financial statements to evaluate the effect or potential effect of netting arrangements on an entity’s financial position, including the effect or potential effect of rights of setoff associated with certain financial instruments and derivative instruments within the scope of this guidance. The guidance is effective for annual reporting periods beginning on or after January 1, 2013. The provisions of this guidance did not have any impact on the Corporation’s financial statements.
