SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Nature of Operations
	National Penn Bancshares, Inc. (the “Company” or “National Penn”), primarily through its national bank subsidiary, National Penn Bank (“NPB”) serves residents and businesses primarily in eastern and central Pennsylvania.  NPB, which has 120 retail branch office locations (119 in Pennsylvania and one in Cecil County, Maryland), is a locally managed community bank providing commercial banking products, primarily loans and deposits.
	The Company’s financial service units consist of an array of investment, insurance and employee benefit services through its non-bank subsidiaries. National Penn’s financial services affiliates consist of National Penn Wealth Management, N.A., including its National Penn Investors Trust Company division; National Penn Capital Advisors, Inc.; Institutional Advisors, LLC; and National Penn Insurance Services Group, Inc., including its Higgins Insurance and Caruso Benefits divisions.
	The Company and its operating subsidiaries compete for market share in the communities they serve with other bank holding companies, community banks, thrift institutions and other non-bank financial organizations, such as mutual fund companies, insurance companies and brokerage companies.
	The Company and its operating subsidiaries are subject to regulations of certain state and federal agencies.  These regulatory agencies periodically examine the Company and its subsidiaries for adherence to laws and regulations.  As a consequence, the cost of doing business may be affected.
	Basis of Financial Statement Presentation
	The accounting policies followed by the Company conform with accounting principles generally accepted in the United States of America (“GAAP”) and predominant practice within the banking industry.
	The consolidated financial statements include the accounts of the Company and the Company’s direct and indirect wholly owned subsidiaries.  The Company’s unconsolidated subsidiaries, representing investments in joint ventures, and other entities are accounted for using the equity method of accounting.  All material inter-company balances have been eliminated.
	Reclassifications
	Certain prior year amounts have been reclassified to conform to current period classifications. These reclassifications did not have a material impact on our consolidated financial condition or results of operations.
	Use of Estimates
	In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the balance sheets, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	The principal estimates that are susceptible to significant change in the near term relate to the allowance for loan losses, goodwill and intangible assets, income taxes, and other-than-temporary impairment. Management’s practice is to retain supporting files for all accounting entries made, but in particular to organize, support and prepare clarifying memoranda for items in the financial statements requiring significant judgment.
	Business Combinations
	At the date of acquisition the Company records the net assets of acquired companies on the consolidated balance sheet at their estimated fair value, and goodwill is recognized for the excess of the purchase price over the estimated fair value of acquired net assets. The results of operations for acquired companies are included in the Company’s consolidated statement of income beginning at the acquisition date. Expenses arising from acquisition activities are recorded in the consolidated statement of income during the period incurred.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	Revenue Recognition
	The Company recognizes revenue in the consolidated statement of income as it is earned and when collectability is reasonably assured. The primary source of revenue is interest income from interest earning assets, which is recognized on the accrual basis of accounting using the effective interest method. The recognition of revenues from interest earning assets is based upon formulas from underlying loan agreements, securities contracts or other similar contracts. Non-interest income is recognized on the accrual basis of accounting as services are provided or as transactions occur. Non-interest income includes fees from wealth management services, deposit accounts, sales of insurance products, cash management and electronic banking services, mortgage banking activities, standby letters of credit and financial guarantees, and other miscellaneous services and transactions.
	Advertising Costs
	Advertising costs are recorded in the period they are incurred within other operating expenses in non-interest expense in the consolidated statement of income. Advertising expense was $5.5 million, $5.6 million, and $5.9 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	Cash and Cash Equivalents
	Cash and due from banks and interest bearing deposits with banks comprise “cash and cash equivalents” on the consolidated balance sheet and statement of cash flows.  Cash held on deposit with other financial institutions is in excess of FDIC insurance limits.
	The Company is required to maintain cash reserves that are considered restrictions on cash and due from banks shown on our consolidated balance sheet. These restrictions consist of required reserves with the Federal Reserve Bank related to our deposit liabilities and cash collateral related to international letters of credit and interest rate swaps with financial institution counterparties. Total restricted cash was $52.4 million and $88.7 million for the years ended December 31, 2013 and 2012, respectively.
	Investment Securities and Other Investments
	Investment securities which are held for indefinite periods of time, which management intends to use as part of its asset/liability strategy, or which may be sold in response to changes in interest rates, changes in prepayment risk, increases in capital requirements, or other similar factors, are classified as available-for-sale and are recorded at their estimated fair value on the consolidated balance sheet. Changes in unrealized gains and losses for such securities, net of tax, are reported in accumulated other comprehensive income as a separate component of shareholders’ equity and are excluded from the determination of net income. Investment securities which have stated maturities for which the Company has the intent and ability to hold until the maturity date are classified as held-to-maturity and are recorded at amortized cost on the consolidated balance sheet.
	Interest from debt securities is recognized in interest income inclusive of adjustments for amortization of purchase premiums and accretion of purchase discounts using the interest method. Dividends from investments in equity securities are accrued in interest income in the consolidated statement of income when they are declared. Gains or losses from the disposition of investment securities are recognized at the trade date as non-interest income in the consolidated statement of income, based on the net proceeds and cost of the securities sold, adjusted for amortization of premiums and accretion of discounts, using the specific identification method.
	When the fair value of an investment security is less than the carrying value, the security is considered to be impaired, and as such the Company reviews the security for the presence of other-than-temporary impairment ("OTTI"). This analysis is performed at least quarterly, and includes the consideration of numerous factors including the time period for which the fair value has been less than the carrying value, curtailment or suspension of dividends or cash flows, deterioration of financial performance or the creditworthiness of the issuer, performance of any underlying collateral, and negative trends in a particular industry or sector. The conclusion as to whether OTTI exists for an investment security is ultimately based upon the Company’s evaluation of the investment’s recoverability above its carrying value and its timing. In addition, the Company considers whether it plans to sell an investment security and whether it may be required to sell the security prior to recovery of its carrying value.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	When the Company concludes an investment security is other-than-temporarily impaired, a loss for the difference between the investment security’s carrying value and the fair value is recognized as a reduction to non-interest income in the consolidated statement of income. For an investment in a debt security, if the Company does not intend to sell the investment security and concludes that it is not more likely than not it will be required to sell the security before recovering the carrying value, which may be maturity, the OTTI charge is separated into the "credit" and "other" components. The "other" component of the OTTI is included in other comprehensive income, net of the tax effect, and the "credit" component of the OTTI is included in the consolidated statement of income as a reduction to non-interest income.
	Other investments are comprised of Federal Home Loan Bank ("FHLB") of Pittsburgh stock and Federal Reserve Bank stock. Federal Reserve Bank stock is an equity interest in the Philadelphia Federal Reserve Bank that is required of member banks. The required subscription for Federal Reserve Bank stock is equal to 6% of National Penn Bank’s capital and surplus. The stock is not transferable and additional purchases or cancellations of the stock are transacted directly with the Federal Reserve Bank of Philadelphia. FHLB stock is an equity interest that can be sold to the issuing FHLB, to other FHLBs, or to other member banks at its par value. Because ownership of these securities is restricted, they do not have a readily determinable fair value. As such, the Company’s other investments are recorded at cost or par value and are evaluated for impairment each reporting period by considering the ultimate recoverability of the investment rather than temporary declines in value.  The Company’s evaluation primarily includes an evaluation of liquidity, capitalization, operating performance, commitments, and regulatory or legislative events.
	Loans and Leases
	Loans that management has the intent to hold for the foreseeable future or until maturity or payoff are considered held for investment and are reported at the amount of unpaid principal, net of unearned income, unamortized deferred fees and origination costs, commitment fees, and premiums or discounts on acquired loans. The Company also estimates an allowance for loan losses, which is netted from the carrying amount of loans presented on the consolidated balance sheet. Interest on loans is calculated based upon the principal amount outstanding. Net deferred fees on Company originated loans, consisting of origination and commitment fees and direct loan origination costs, are amortized over the contractual life of the related loans using the interest method, which results in an adjustment of the related loan’s yield. Premiums or discounts resulting from loans acquired are included or netted with the balance of unpaid principal on the consolidated balance sheet and are also deferred and amortized over the contractual life of the loan using the interest method.
	Loans are placed on non-accrual status and accrual of interest is suspended on a loan when management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that collection of all contractually required payments is no longer probable. When a loan is on non-accrual status, payments are applied in their entirety to principal. If a borrower’s financial condition improves to the point where management believes that collection of the remaining principal and interest is probable, management may restore the loan to accrual status, at which time payments received are applied to both principal and interest and recognition of interest income continues. Generally, loans are placed on non-accrual status when they reach 90 days past due based on the contractual terms of the loan agreement.
	Direct financing leases are carried at the aggregate of the lease payments plus the estimated residual value of the leased property, net of unearned income and deferred initial direct costs. Interest income on leases is recognized using the interest method over the lease term, which incorporates amortization of deferred initial direct costs as an adjustment to the lease’s yield. Residual values for leases are reviewed for impairment at least annually based upon historical performance, independent appraisals, and industry data. Valuation adjustments to residual values are included in other operating expenses within non-interest expense in the consolidated statement of income. Gains or losses from the sale of leased assets are also included in other operating income within non-interest income in the statement of income.
	Equipment underlying leases to customers for which a sale to the lessee is not implied or imminent is reported on the consolidated balance sheet within premises and equipment and is depreciated over its useful life. In the event that the lessee fails to meet a contractual leasing obligation, the remaining carrying value is considered a non-performing asset, including any underlying equipment which may be repossessed.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	Loans Held-For-Sale
	Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value on the consolidated balance sheet, and these loans are traditionally sold servicing released. The fair value of loans held-for-sale is estimated based upon the contractually agreed upon sales price to investors. Write-downs to fair value, if any, are reflected through a valuation allowance netted from the cost basis of the loans on the consolidated balance sheet and a related expense recorded as a reduction to mortgage banking income in the consolidated statement of income. At disposition, the difference between the net proceeds received and the carrying value of the loan is recorded as a gain or loss within mortgage banking income in the consolidated statement of income. Estimated credit losses, if any, on loans transferred to held-for-sale, which management previously intended to hold for investment, are charged to the allowance at the time of transfer. Non-credit related losses, if any, or subsequent gains or losses upon disposition are recorded in other operating expenses within non-interest expense on the consolidated statement of income. Valuations of non-mortgage loans transferred to held-for-sale are performed on an individual basis.
	Non-Performing Assets
	Assets which are otherwise considered earning assets may cease to perform according to their original terms and become non-performing assets. The Company’s non-performing assets consist of non-accrual loans, loans defined as troubled debt restructurings, and other real estate owned. On an ongoing basis, the Company monitors economic conditions and reviews borrower financial results, collateral values, and compliance with payment terms and covenant requirements in order to identify problems in loan relationships. All problem loans are reviewed regularly for impairment. When management believes that the collection of all or a portion of principal and interest is no longer probable, the accrual of interest is suspended, and payments for interest are applied to principal until the Company determines that all remaining principal and interest can be recovered. This may occur at any time regardless of delinquency status, however, loans 90 days or more past due are reviewed monthly to determine whether interest accrual should continue. Loans for which the accrual of interest has been suspended are categorized as non-accrual loans.
	Through negotiations with a borrower, the Company may restructure a loan prior to or at its contractual maturity. Modification of a loan’s terms constitutes a troubled debt restructuring ("TDR") if the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession that it would not otherwise consider. The Company restructures loans in an attempt to preserve or improve the economic recovery of principal and/or interest due from a borrower. Not all modifications of loan terms automatically result in a TDR, only modifications which are concessions (terms not otherwise attainable) to a borrower experiencing financial distress constitute TDRs. TDRs are disclosed as restructured loans. TDRs and non-accrual loans comprise the Company’s impaired loans which are evaluated individually for purposes of determining the allowance for loan losses.
	Other real estate owned ("OREO") results from the acquisition of real estate through foreclosure, abandonment, or conveyance of deed in lieu of foreclosure of a loan. OREO is carried on the consolidated balance sheet within OREO and other repossessed assets at the estimated fair value of the real estate less expected costs to sell at the acquisition date. Any loss upon reclassification from loans to OREO is recognized as a charge to the allowance for loan losses. During the holding period, OREO continues to be measured at the lower of its carrying amount or estimated fair value less costs to sell, and any valuation adjustment and gains or losses upon disposition are recognized within other operating income within non-interest income in the consolidated statement of income. OREO is evaluated individually rather than as a group, unless the circumstances render the group measurement to be a more appropriate basis as determined by management.
	Significant Concentrations of Credit Risk
	Most of the Company’s activities are with customers located throughout eastern and central Pennsylvania. The Company’s commercial portfolio has a concentration in loans to commercial real estate investors and developers as defined by regulation. There are numerous risks associated with commercial loans that could impact the borrower’s ability to repay on a timely basis. They include, but are not limited to: the owner’s business expertise; changes in local, national, and in some cases international economies; competition; governmental regulation; and the general financial stability of the borrowing entity.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	The Company attempts to mitigate these risks by completing an analysis of the borrower’s business and industry history, the borrower’s financial position, as well as that of the business owner. The Company will also require the borrower to periodically provide financial information on the operation of the business over the life of the loan. In addition, most commercial loans are secured by assets of the business or those of the business owner, which can be liquidated if the borrower defaults, along with the personal surety of the business owner.
	Allowance for Loan Losses
	Management conducts an analysis of the loan portfolio to estimate the amount of the allowance for loan losses (allowance) which is adequate to absorb inherent losses on existing loans. The allowance is established through a provision for loan losses charged as an expense in the consolidated statement of income. Loans are charged-off to the allowance when management believes that the collectability of the principal is less than probable and sufficient information exists to make a reasonable estimate of the inherent loss or a loss event has been confirmed.
	The evaluation of the adequacy of the allowance includes an analysis of individual loans and groups of homogeneous loans. Loans in the portfolio are segregated by risk characteristics. This is primarily accomplished by separating loan types as well as loan risk designations including, but not limited to: loans classified as Substandard or Doubtful as defined by regulation; loans criticized internally or designated as Special Mention; and loans specifically identified by management as impaired.
	The analysis of individual loans and analytical processes performed by management in the calculation of the allowance is ongoing, and adjustments may be made based on the assessment of internal and external influences on credit quality. Those influences include, but are not limited to: unemployment, delinquency and non-accrual rates, trends in loan volume, portfolio growth, portfolio concentrations, Board and loan review oversight, exceptions to policy, competition and other external factors, and/or changes in value of collateral dependent loans.
	The Company evaluates economic conditions and reviews borrower financial results, collateral values, and compliance with contractual payment terms and covenant requirements in order to monitor loan relationships. A classified loan is one which is paying as agreed, but based upon management’s analysis is determined to be inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. All classified loans are evaluated to determine whether they are non-performing or whether it is probable they will become non-performing, based on facts and circumstances.
	When management believes that the collection of all or a portion of principal and interest is no longer probable, the loan is placed on non-performing status, accrual of interest is suspended, and payments for interest are applied to principal until the Company determines that all remaining principal and interest can be recovered. This may occur at any time regardless of delinquency, however, loans 90 days or more past due are reviewed monthly to determine whether the accrual of interest should continue. Because all or a portion of the contractual cash flows are not expected to be collected in accordance with the underlying loan agreements, the loan is considered to be impaired, and the Company estimates and records impairment based upon the present value of the expected cash flows it will be able to collect.
	Values of collateral securing commercial loans are confirmed through regular updates and reviews, but at a minimum are updated every twelve months for all loans designated as Special Mention or Classified, every six to nine months for land loans. During the period between appraisal order and completion, management makes an estimate of collateral values based on available market information and other recent appraisal results.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	Specific Reserves
	Specific reserves are an estimation of losses specific to individual impaired loans. All non-performing and restructured loans are evaluated to determine the amount of specific reserve or the required charge-off, if any, to reduce the current carrying value of the individual loan to its net realizable value based on an analysis of the available sources of repayment, including liquidation of collateral. The net realizable value is estimated as the present value of expected future cash flows discounted at the loan’s effective interest rate, the observable market price if the loan is expected to be sold, or, if collateral dependent, the estimated fair value of the collateral less costs to sell based on recent appraisals. A specific reserve may be established instead of a charge-off when sufficient information exists to make a reasonable estimate of the loss but where a loss event has not yet been confirmed. While every impaired loan is individually evaluated, not every impaired loan requires a specific reserve. Specific reserves fluctuate based on changes in the collectability of underlying loans and any previously recorded charge-offs. A confirmed loss event could be a payment delinquency of typically 90 days or greater, bankruptcy, fraud, death, or defunct status of a business, project or development. Impaired loans are excluded from the calculation of allocated reserves as described below.
	Charge-offs
	Commercial and industrial loans are charged-off in whole or in part when they become 90 or more days delinquent based upon the terms of the underlying loan contract and when full collectability of the principal balance is no longer probable. Because all or a portion of the contractual cash flows are not expected to be collected, the loan is considered to be impaired, and the Company estimates and records impairment based upon the present value of the expected cash flows it will be able to collect. Loans in bankruptcy and loans to defunct businesses are charged-off to the estimated fair value of collateral, less costs to sell.
	Commercial real estate loans are charged-off in whole or in part when they become 90 or more days delinquent based upon the terms of the underlying loan contract and when a collateral deficiency exists. Because all or a portion of the contractual cash flows are not expected to be collected, the loan is considered to be impaired, and the Company estimates and records impairment based upon the expected cash flows it will be able to collect, which is generally from the liquidation of the pledged collateral. Loans in bankruptcy and loans to defunct projects or development businesses are charged-off to the estimated fair value of collateral, less costs to sell.
	Consumer loans are charged-off when they become non-performing, which is no later than when they become 90 days past due. At that time, the amount of the estimated collateral deficiency, if any, is charged-off for loans secured by collateral, all other loans are charged-off in full. Loans in which the borrower is in bankruptcy are charged-off within 60 days of receipt of notification of the bankruptcy filing or within the timeframes specified in policy, whichever is shorter, unless it can be established that repayment is likely to occur. Loans with collateral are charged-down to the estimated fair value of collateral, less costs to sell.
	Allocated Reserves
	Allocated reserves represent an allowance for groups of homogeneous loans which are similar in nature and as such are not individually evaluated for impairment. Allocated reserves are applied to both the non-criticized and criticized and classified portions of each portfolio. The Company segregates the loan portfolio into strata based upon risk characteristics which reflect the behavior and performance of the underlying loans.
Classified and criticized loans are stratified based upon underlying loan types and characteristics and are separately evaluated to determine the amount of reserve considered adequate. Loss factors are based on the loan type, performance trends, portfolio characteristics, risk, and assigned ratings.
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
For pass-rated loans, an estimate of inherent loss is made by applying portfolio-specific environmental and historical loss factors to the period-end balances of each loan category. Environmental factors are applied in addition to historical loss factors to reflect trends which management believes are not fully incorporated in historical net charge-off ratios. Environmental factors include: unemployment, delinquency and non-accrual rates, trends in loan volume and portfolio growth, portfolio concentrations, Board and loan review oversight, exceptions to policy, experience of management, competition and other external factors, and changes in the fair value of collateral dependent loans. A historical loss factor is generated using actual losses for the preceding twelve quarters from the current quarter end. The loss percentages are weighted to utilize the most relevant and current loss experience.
Unallocated Reserve
The unallocated reserve addresses inherent losses not included elsewhere in the allowance. It represents an element in the adequacy of the allowance given the nature of the calculation and the inherent imprecision and uncertainty as to estimated losses.
Premises and Equipment
Land is stated at cost. Buildings, equipment and leasehold improvements are stated at cost less accumulated depreciation and amortization which is generally computed on a straight-line basis over the estimated useful life of the asset. Leasehold improvements are amortized using the straight-line method over the lesser of the estimated economic life or the lease term. Depreciation and amortization expense for premises and equipment is included in premises and equipment expense in the consolidated statement of income.
The Company leases certain premises and equipment under non-cancellable operating leases. Certain leases contain renewal options and rent escalation clauses calling for rent increases over the term of the lease. Rental expense for all leases which contain escalation clauses are accounted for on a straight-line basis over the lease term.
Expenses for maintenance and repairs are recorded in premises and equipment expense in the consolidated statement of income as they are incurred.
Accrued Interest Receivable
The Company records interest income on interest earning assets on the accrual basis which results in the recognition of interest income recorded in the consolidated statement of income before it is received. The consolidated balance sheet includes the amount of interest earned on the accrual basis of accounting but not yet received as of the date presented. The balance is primarily comprised of interest earned on loans to customers and dividends and interest on investment securities.
Bank Owned Life Insurance
The Company invests in bank owned life insurance ("BOLI") policies that provide earnings to help cover the cost of employee benefit plans. The Company is the owner and beneficiary of the life insurance policies it purchased directly on a chosen group of employees or it obtained through acquisitions of other institutions that previously purchased the policies. The policies are carried on the Company’s consolidated balance sheet at their cash surrender value and are subject to regulatory capital requirements. The determination of the cash surrender value includes a full evaluation of the contractual terms of each policy and assumes the surrender of policies on an individual-life by individual-life basis. Additionally, the Company periodically reviews the creditworthiness of the insurance companies that have underwritten the policies. Earnings accruing to the Company are derived from the general account investments of the insurance companies. Increases in the net cash surrender value of BOLI policies and insurance proceeds received are not taxable and are recorded in non-interest income in the consolidated statement of income.

Goodwill and Other Intangible Assets
Goodwill is recognized for the excess of the purchase price over the estimated fair value of acquired net assets in a business combination. Goodwill is not amortized but is reviewed for potential impairment on at least an annual basis, which the Company performs during the second quarter of each year. The Company has the option of performing a qualitative assessment to determine whether it is more likely than not that the fair value of one of the Company’s identified reporting units is less than its carrying value. If the results of the qualitative assessment indicate the potential for impairment, the Company would perform the two-step goodwill impairment analysis.
In performing the two-step goodwill impairment analysis, if necessary, the estimated fair value of each reporting unit is compared to its carrying value, inclusive of the goodwill assigned to it. If the carrying value of a reporting unit exceeds the estimated fair value, an indicator of goodwill impairment exists and a second step is performed to determine if any goodwill impairment exists. In the second step, the Company calculates the implied value of goodwill by emulating a business combination for each reporting unit. This step subtracts the estimated fair value of net assets in the reporting unit from the step one estimated fair value to determine the implied value of goodwill. If the implied value of goodwill exceeds the carrying value of goodwill allocated to the reporting unit, goodwill is not impaired, but if the implied value of goodwill is less than the carrying value of the goodwill allocated to the reporting unit, an impairment charge is recognized for the difference in the consolidated statement of income with a corresponding reduction to goodwill on the consolidated balance sheet. The Company’s business segments are its reporting units which are community banking and other for purposes of the goodwill impairment analysis.
In performing its analysis of goodwill impairment, the Company makes significant judgments, particularly with respect to estimating the fair value of each reporting unit and if the second step is required, estimating the fair value of net assets. The Company evaluates each reporting unit and estimates a fair value as though it were an acquirer. The estimates utilize historical data, cash flows, and market and industry data specific to each reporting unit. Industry and market data is used to develop material assumptions such as transaction multiples, required rates of return, control premiums, transaction costs and synergies of a transaction, and capitalization.
On an interim basis, the Company evaluates whether circumstances are present that could indicate potential impairment of its goodwill. These circumstances include, but are not limited to, prolonged trading value of the Company’s common stock relative to its book value, adverse changes in the business or legal climate, actions by regulators or loss of key personnel. When the Company determines that these or other circumstances are present, the Company tests the carrying value of goodwill for impairment at an interim date.
Other intangible assets are specifically identified intangible assets created from a business combination. Core deposit intangibles represent the value of checking, savings and other acquired, low-cost deposits. Core deposit intangibles are amortized over the lesser of the estimated lives of deposit accounts or ten years on an accelerated basis. Decreases in deposit lives may result in increased amortization and/or an impairment charge. Other intangible assets also include customer lists and covenants not to compete. These assets are amortized over the lesser of their contractual life or estimated economic life on a straight-line basis.
Unconsolidated Investments Under the Equity Method
The Company invests in partnerships and other non-consolidated businesses. These investments typically range from 20% ownership up to 50% and are accounted for using the equity method. The Company’s proportionate share of income or loss on equity method investments is recorded in non-interest income in the consolidated statement of income using the accrual basis of accounting. Cash received by the Company for dividends or distributions on these investments reduces the carrying value of the equity method investment on the consolidated balance sheet. These investments are reviewed at least annually for other-than-temporary declines below the investment’s carrying value. Consideration is given to a number of variables, including any expected tax credits or other similar benefits from each investment. Impairment charges are recorded as a reduction to the investment’s carrying value on the consolidated balance sheet and to non-interest income in the consolidated statement of income.
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
Repurchase Agreements
The Company’s repurchase agreements are secured borrowing transactions collateralized by investment securities. The Company sells investment securities to counterparties with an agreement to repurchase the exact or substantially the same securities at a specified date. On the trade date, the Company records a liability on the consolidated balance sheet for the amount for which securities will be subsequently reacquired, including accrued interest, based upon the contractual term of the transaction. Interest expense from repurchase agreements is recognized on the accrual basis of accounting in the consolidated statement of income.
The securities underlying repurchase agreements are identified and disclosed as pledged for this purpose in the notes to the financial statements. The investment securities remain on the Company’s consolidated balance sheet and are accounted for consistent with the Company’s other investment securities available-for-sale. Repurchase agreements are satisfied by the payment of cash from the Company to the counterparty at which time the securities identified in the transaction are no longer considered pledged.
Subordinated Debentures
At the beginning of 2013, the Company had five established statutory business Trusts: NPB Capital Trust II, NPB Capital Trust III, NPB Capital Trust IV, NPB Capital Trust V and NPB Capital Trust VI (“Trusts”). On March 7, 2013, the Company redeemed all of the subordinated debentures issued by NPB Capital Trust II. The Company owns all of the common capital securities of the remaining Trusts. The Trusts issued preferred capital securities to investors and invested the proceeds in junior subordinated debentures issued by the Company. These debentures are the sole assets of the Trusts, which are considered variable interest entities. The Company is not the variable interest holder, and as such does not consolidate the Trusts. The liabilities to the Trusts are reflected as subordinated debentures on the Company’s consolidated balance sheet, and the common capital securities are included in other assets. Interest is paid on amounts borrowed from the Trusts and recorded in interest expense in the consolidated statement of income on the accrual basis of accounting.
Costs related to the issuance of subordinated debentures are being amortized over the life of the instruments as an increase to interest expense in the consolidated statement of income using the interest method. The unamortized portion of the issuance costs is included within other assets on the consolidated balance sheet.
The Company’s maximum exposure to the Trusts is $75 million, which is the Company’s liability to the Trusts and includes the Company’s investment in the Trusts.
On January 1, 2007, the Company made an accounting policy election to record $65.2 million of debentures issued to NPB Capital Trust II on August 20, 2002 at fair value on the consolidated balance sheet. Prior to its redemption in the first quarter of 2013, changes in the estimated fair value for each reporting period were reported as net gains (losses) from fair value changes within non-interest income in the consolidated statement of income.
Employee Benefit Plans
The Company accrues for benefits to employees and executive officers resulting from established plans and other contracts which are generally non-contributory. The benefits associated with these arrangements and plans are earned over a service period, and the Company estimates the amount of expense applicable to each plan or contract and includes it in salaries, wages and employee benefits expense in the consolidated statement of income for each period. The estimated obligations for the plans and contracts are reflected as liabilities on the consolidated balance sheet. The determination of each obligation and the related expense is based upon formulas in plan documents or agreements, but also requires judgment on the part of the Company to determine the assumptions applied to each formula. In addition, for the non-contributory pension plan there are amounts included in accumulated other comprehensive income (loss) related certain costs which require recognition over the course of several reporting periods.
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
Income Taxes
The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recorded on the consolidated balance sheet for future tax events that arise from the difference between the financial statement and tax basis of assets and liabilities as measured by the enacted tax rates. Changes in tax rates are recognized in the Company’s financial statements during the period they are enacted. When a deferred tax asset or liability, or a change thereto, is recorded on the consolidated balance sheet, deferred tax expense or benefit is recorded within the income tax expense line of the consolidated statement of income for purposes of determining the current period’s net income.
Deferred tax assets are recorded on the consolidated balance sheet at net realizable value. The Company periodically performs an assessment to evaluate the amount of deferred tax assets it is more likely than not to realize. Realization of deferred tax assets is dependent upon the amount of taxable income expected in future periods, as tax benefits require taxable income to be realized. If a valuation allowance is required, the deferred tax asset on the consolidated balance sheet is reduced via a corresponding income tax expense in the consolidated statement of income.
The Company recognizes the benefit of a tax position in the financial statements only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. For these analyses, the Company may engage attorneys to provide opinions related to certain positions. Any interest and penalties, when applicable, related to uncertain tax positions is recognized in income tax expense in the consolidated statement of income.
Financial Instruments with Off-Balance-Sheet Risk
The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit, standby letters of credit, forward sale commitments, and interest rate swaps. Certain of those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized on the consolidated balance sheet. The contract or notional amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.
The Company’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of these instruments. The Company uses the same credit policies in making commitments and contractual obligations as it does for on-balance-sheet instruments. For interest rate swaps, the contract or notional amounts do not represent exposure to credit loss, but rather the credit risk is consistent with the estimated fair value due from counterparties to these contracts. The Company controls the credit risk of its interest rate swap agreements through credit approvals, limits and monitoring procedures. The Company reflects its estimate of credit risk for these instruments (including unfunded commitments, letters of credit, and interest rate swaps) in other liabilities on the consolidated balance sheet with the offsetting expense recorded in other operating expenses in the consolidated statement of income.
Financial instruments that are derivatives are reported at estimated fair value within other assets or other liabilities on the consolidated balance sheet. An instrument is generally considered a derivative if it is based on one or more underlyings, no (or a minimal) initial net investment is required, and the contract can be net settled. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship. For derivatives not designated or qualifying as hedges, the gain or loss is included in the determination of net income. For derivatives designated and qualifying as hedges, only the ineffective portion is included in the determination of net income, the effective portion is included in the determination of net income consistent with the hedged item.
The Company enters into interest rate swaps (swaps) to facilitate customer transactions and meet their financing needs. These swaps are considered derivatives, but are not designated in hedging relationships. These instruments have interest rate and credit risk associated with them. To mitigate the interest rate risk, the Company enters into offsetting interest rate swaps with counterparties. The counterparty swaps are also considered derivatives and are also not designated in hedging relationships. Interest rate swaps are recorded within other assets or other liabilities on the consolidated balance sheet at their estimated fair value. Changes to the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the consolidated statement of income.
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
The Company may enter into interest rate swap contracts in order to hedge its exposure to the variability of cash flows on certain floating-rate obligations. Cash flow hedges are intended to convert liabilities from a floating-rate instrument to a fixed-rate instrument. The Company’s intention is to design cash flow hedges to qualify for hedge accounting, and as such the estimated fair value of the hedge would be recorded either in other assets or other liabilities with an offset, after estimated taxes, recorded in accumulated other comprehensive income (loss). The ineffective portion of the hedging relationship would be recorded in other operating expenses in the consolidated statement of income. Amounts would be reclassified from accumulated other comprehensive income (loss) to interest expense in the consolidated statement of income during the period the hedged item affects earnings. Cash flows associated with the hedges are treated consistently with the cash flows of the hedged item during the period in which they occur.
The Company periodically enters into interest rate lock commitments with its mortgage loan customers whose loans are intended for sale after the loan is closed. These commitments are derivatives and, as such, are reported on the consolidated balance sheet at their estimated fair value. The Company’s methodology for estimating the fair value of these derivatives is based upon the change in pricing of mortgage-backed securities with similar interest rates and duration. To hedge the fair value risk associated with changing interest rates on these commitments, the Company enters into forward commitments to sell the loans. These hedges are economic hedges and are not designated in hedging relationships. The forward sale commitments are also derivatives and are recorded on the consolidated balance sheet at their estimated fair value. The Company’s methodology for valuing these derivatives is based upon the fair value of the closed loans and the change in fair value of the interest rate lock commitments, as previously described. The net change in the estimated fair value of the derivatives for commitments to customers and forward loan sale commitments during each period is recorded in mortgage banking income in the consolidated statement of income.
The Company estimates the fair value of letters of credit as the fees paid by the customer or charged for the arrangement. The fair value is recorded in other liabilities on the consolidated balance sheet, and subsequently, the income is recognized in other operating income within non-interest income in the consolidated statement of income over the contractual life of the instrument. If required to perform on a standby letter of credit, the Company records an amount due from the customer, which is recorded net of any unaccreted liability. Additional amounts estimated to be uncollectible, net of estimated proceeds from collateral, are charged-off against the appropriate allowance on the consolidated balance sheet.
Interest rate swap derivatives with the same counterparty and subject to master netting arrangements are not offset on the consolidated balance sheet. For additional detail refer to Footnote 13 within this section.
Accumulated Other Comprehensive Income
Accumulated other comprehensive income ("AOCI") includes items that are subject to periodic measurement on the consolidated balance sheet but are not included in the determination of net income for the period in the consolidated statement of income. As such, amounts recorded in AOCI are on an after-tax basis and consist primarily of unrealized gains or losses on investment securities available-for-sale and changes in pension obligations.
Share-Based Compensation
The Company has certain share-based employee and director compensation plans. The related share-based employee compensation is included in salaries, wages and employee benefits expense in the consolidated statement of income during the period in which it is earned. Share-based director compensation expense is included in other operating expense in the consolidated statement of income. The compensation cost for share-based compensation arrangements is determined based upon the estimated fair value of the award at the grant date and is recognized as an expense over the service period. Performance criteria for share-based awards are factored into the amount of expense recognized when applicable. The Company records tax benefits of share-based payments as a financing cash inflow and corresponding operating cash outflow in the consolidated statement of cash flows during the period in which they occur.
Option awards are granted with an exercise price at least equal to the market price of the Company’s stock at the date of grant. Option awards vest at such times as are determined by the Compensation Committee of the Board of Directors at the time of grant, but not before one year from the date of grant or later than five years from the date of grant. The options have a maximum term of ten years for incentive stock options or ten years, one month for non-qualified stock options.
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
The Company utilizes the Black-Scholes option valuation model to estimate the fair value of options granted.  The model is sensitive to changes in assumptions which can materially affect the fair value estimate:
•	The risk-free interest rates used are from published U.S. Treasury zero-coupon rates for bonds approximating the expected term of the option as of the option grant date;
•	The expected dividend yield is computed based on the Company’s current dividend rate; and
•	The Company relies exclusively on historical volatility as an input for determining the estimated fair value of stock options. The Company determines expected volatility based on the expected life of the option.
In determining the expected life of the option grants, the Company observes the actual terms of prior grants with similar characteristics and the actual vesting schedule of the grants.
Share-based payments are also granted in the form of restricted stock awards or units. Restricted stock is granted with service criteria and may also include performance criteria. The fair value of each award is estimated based on the fair value of the Company’s common stock on the date of grant.
Share-based payment plans are further described in Footnote 17 within this section.
Treasury Stock
Shares of the Company’s common stock which are repurchased on the open market are classified as treasury stock on the consolidated balance sheet. Treasury stock is recorded at the cost at which it was obtained in the open market, and at the date of reissuance, treasury stock on the consolidated balance sheet is reduced by the cost for which it was purchased using specific identification, on a first-in, first-out basis.
Earnings Per Share
Earnings per share is calculated on the basis of the weighted-average number of common shares outstanding during the year. All per share information in the financial statements is adjusted retroactively for the effect of stock dividends and splits.
Diluted shares and earnings per share take into account the potential dilution that could occur if securities or other contracts to issue common stock were exercised and converted into common stock. The dilutive effect of stock options, warrants, and other instruments is calculated using the treasury stock method.
Recent Accounting Pronouncements
Goodwill
In September 2011, the Federal Accounting Standard Board ("FASB") simplified how entities test goodwill for impairment, whereby an entity has the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after its assessment, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it would not have to perform the current two-step goodwill impairment test. This amendment was effective for the Company for its fiscal year beginning January 1, 2012 and the adoption of this standard did not have a material effect on the financial condition or results of operations of the Company.
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
Comprehensive Income
In June 2011, the FASB released a standard requiring comprehensive income to be presented either in a single continuous statement or in two separate but consecutive statements. The single continuous statement format combines other comprehensive income, its components and total comprehensive income with the consolidated statement of income. In the two statement approach, the first statement would be the statement of income immediately followed by a separate statement which includes the components of other comprehensive income, total other comprehensive income and total comprehensive income. The standard was effective for the Company beginning January 1, 2012 and requires retrospective application. The Company early adopted the two statement approach for the year ended December 31, 2011 by including a consolidated statement of comprehensive income after the consolidated statement of income in this Report.
In February 2013, the FASB released guidance on disclosures about reclassifications out of accumulated other comprehensive income. The issuance of this guidance now requires entities to disclose:
•	For items reclassified out of accumulated other comprehensive income ("AOCI") and into net income in their entirety, the effect of the reclassification on each affected net income line item; and
•	For AOCI reclassification items not reclassified in their entirety into net income, a cross reference to the related footnote where additional information on the effect of the reclassification is disclosed.
The adoption of this disclosure requirement did not materially impact the Company's financial condition or result of operations.
Balance Sheet Offsetting
In January 2013, the FASB updated the disclosure requirements surrounding the offsetting of assets and liabilities on an entity's balance sheet. As part of the updated requirements, an entity shall disclose information to enable users of its financial statements to evaluate the effect or potential effect of rights of setoff associated with recognized derivatives, repurchase agreements, reverse repurchase agreements, and securities lending or securities borrowing transactions that are either (1) offset in the balance sheet or (2) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset on the balance sheet. The Company adopted this guidance for the year ended December 31, 2013. Adoption of this guidance did not materially impact the Company's financial condition or results of operations, however did result in additional disclosures.
Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists
In July 2013, the FASB issued explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The guidance requires, with limited exception, that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a DTA for a net operating loss carryforward, or similar tax loss, or a tax credit carryforward. The new guidance is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption and retrospective application are permitted. As this guidance only impacts financial statement presentation and related footnote disclosures, it will have no effect on the Company's financial position or results of operations.
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
Troubled Debt Restructurings by Creditors
In January 2014, the FASB issued guidance to clarify when banks should reclassify mortgage loans collateralized by residential real estate properties from the loan portfolio to other real estate owned. The FASB defined an in-substance repossession or foreclosure to have occurred and a creditor is considered to have taken physical possession of residential real estate collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. The effective date is for annual periods, and interim periods within those annual periods, beginning after December 15, 2014, with early adoption permitted. The Company does not expect adoption of this guidance to have a material effect on the financial condition or results of operations of the Company.

Evaluation of Impairment of Securities
The Company did not record any other-than-temporary impairment ("OTTI") losses for the year ended December 31, 2013. During the year ended December 31, 2012, the Company recorded $0.2 million of OTTI on one equity security.
As of December 31, 2013 and 2012, accumulated other comprehensive income does not include any impairment related charges for the non-credit-related components of OTTI.
The majority of the investment portfolio is comprised of U.S. Government Agency securities (mortgage-backed and collateralized mortgage obligations) and state and municipal bonds. For the investment securities in an unrealized loss position, the Company has concluded, based on its analysis, that the unrealized losses are primarily caused by the movement of interest rates, and the contractual terms of these investments do not permit the issuer to settle the securities at a price less than the par value of the investment.
At December 31, 2013, gross unrealized losses totaled $47.0 million, and the gross unrealized losses of securities in an unrealized loss position for twelve months or longer totaled $10.7 million, of which $2.3 million is attributable to state and municipal bonds and $8.0 million attributable to agency mortgage-backed securities and collateralized mortgage obligations.  The Company evaluates a variety of factors in concluding whether securities are other-than-temporarily impaired.  These factors include, but are not limited to, the type and purpose of the bond, the underlying rating of the bond issuer, and the presence of credit enhancements (i.e. state guarantees, municipal bond insurance, collateral requirements, etc.). As a result of its review and considering the attributes of the individual securities, the Company concluded that the securities were not other-than-temporarily impaired.
Because the Company does not intend to sell these investments and it is not more likely than not it will be required to sell these investments before a recovery of carrying value, which may be maturity, the Company does not consider the securities in an unrealized loss position for twelve months or longer to be other-than-temporarily impaired.
Other securities on the Company’s consolidated balance sheet totaled $63.7 million and $68.4 million as of December 31, 2013 and December 31, 2012, respectively. The balance includes Federal Loan Home Bank ("FHLB") of Pittsburgh stock and Federal Reserve Bank stock. These securities lack a market, and as such they are carried at par/cost since their fair value is not readily determinable. The Company evaluates, and will continue to evaluate, these securities for impairment each reporting period and has concluded the carrying value of these securities is not impaired. During 2013, the FHLB of Pittsburgh repurchased $4.6 million, net, of its capital stock from the Company at par/cost. Also, during 2013 and 2012 the Company received and recorded dividends on its FHLB stock.

	At the beginning of 2013, the Company had five established statutory business Trusts: NPB Capital Trust II, NPB Capital Trust III, NPB Capital Trust IV, NPB Capital Trust V and NPB Capital Trust VI (“Trusts”). On March 7, 2013, the Company redeemed all of the subordinated debentures issued by NPB Capital Trust II. The Company owns all of the common capital securities of the remaining Trusts. The Trusts issued preferred capital securities to investors and invested the proceeds in junior subordinated debentures issued by the Company. These debentures are the sole assets of the Trusts.
	Details of the Company’s obligations to the Trusts as of December 31, 2013 are as follows:
	Trusts		Principal		Issued		Maturity		Interest Rate
	NPB Capital Trust III		$20.6 Million		February 20, 2004		April 23, 2034		3 mo. LIBOR + 2.75% margin

	All of the Trusts can currently be called in whole or in part.
	On March 7, 2013, the Company redeemed all of the 7.85% subordinated debentures accounted for at fair value - Cumulative Trust Preferred Securities issued by NPB Capital Trust II. The aggregate redemption of the debentures was $66.1 million, inclusive of $0.9 million of accrued distributions. This debenture was reported on the consolidated balance sheet at its fair value of $67.3 million at December 31, 2012.
	All the foregoing junior subordinated debentures qualify under the risk-based capital guidelines of the Federal Reserve as Tier 1 capital, subject to certain limitations. In each case, the debentures are callable by National Penn, subject to any required regulatory approvals, at par, in whole or in part, at any time after five years from issuance. In each case, the Company's obligations under the junior subordinated debentures and related documents, taken together, constitute a full, irrevocable and unconditional guarantee on a subordinated basis by the Company of the obligations of the Trusts under the preferred securities.

	9. CONTINGENCIES
	In the normal course of business, the Company is named as a defendant in various lawsuits.  Accruals are established for legal proceedings when information related to the loss contingencies indicates that a loss settlement is both probable and can be estimated. At December 31, 2013, the Company did not have material amounts accrued for legal proceedings as it is the opinion of management that the resolution of such suits will not have a material effect on the financial position or results of operations of the Company. The outcome of legal proceedings is inherently uncertain, and as a result, the amounts recorded may not represent the Company's ultimate loss upon resolution. Thus, the Company’s exposure and ultimate losses may be higher or lower than amounts accrued or estimated as reasonably possible exposure.

In the fourth quarter of 2013, the Board of Directors authorized the repurchase of up to five percent (5%) of the outstanding shares of National Penn common stock during 2014. The authorization of this repurchase plan superseded all pre-existing share repurchase plans.
	On January 28, 2014, the Company announced the repurchase of 7 million shares, of the 25.9 million outstanding shares, which Warburg Pincus held in NPBC common stock. Warburg Pincus maintains a 13.6% position in the Company, down from the 17.8% at December 31, 2012.
	In 2012, the Board of Directors authorized and the Company completed the repurchase of 7.5 million shares of National Penn's common stock, which represented approximately five percent (5%) of the outstanding shares.
	Dividend Reinvestment and Stock Purchase Plan (“DRP”)
	The Company has a dividend reinvestment and stock purchase plan that provides a 10% discount on dividends reinvested as well as new cash purchases made under the terms of the Plan. The Plan was amended on June 18, 2009 and allows voluntary cash contributions in amounts not to exceed $10,000.
	Cash Dividends
	The Company declared and paid cash dividends of $0.10 per share for each of the last three quarters of 2013, totaling $43.7 million.
	In 2012, the Company declared and paid cash dividends of $0.41 per share, or $61.4 million, to common shareholders, including an additional $0.10 per share, or $15.0 million, cash dividend paid in the fourth quarter of 2012 in lieu of a first quarter 2013 cash dividend.

	Commitments to sell mortgages to investors	15,349			51,125
	Letters of credit	142,246			127,435
	Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party.  Those guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. The Company also obtains collateral, such as real estate or liens on their customer’s assets depending on the customer, for these types of commitments. The credit risk involved in issuing letters of credit is essentially the same as that involved in lending to customers, however, since the Company does not anticipate having to perform on material amounts of standby letters of credit, the risk is estimated to be substantially less than the contractual amount of commitments outstanding.  Fair values of letters of credit were not considered to be material as of December 31, 2013 and 2012.
	The Company enters into interest rate lock commitments with its mortgage loan customers, a portion of which are intended for sale in the future. The portion of the commitments that are intended for sale in the future are derivatives and, as such, are reported on the consolidated balance sheet at their estimated fair value. To hedge the fair value risk associated with changing interest rates on these commitments, the Company enters into forward sale commitments to sell the closed loans to investors. These hedges are economic hedges and are not designated in hedging relationships. The forward sale commitments to investors are also derivatives and are recorded on the consolidated balance sheet at their estimated fair value.
	Summary information regarding interest rate swap derivative positions which were not designed in hedging relationships are as follows:

	The Company enters into interest rate swaps (“swaps”) to facilitate customer transactions and meet their financing needs. These swaps are considered derivatives but are not designated in hedging relationships. These instruments have interest rate and credit risk associated with them. In response, the Company enters into offsetting interest rate swaps with counterparties for interest rate risk management purposes. The counterparty swaps are also considered derivatives and are also not designated in hedging relationships. Changes in the fair value of the customer and counterparty swaps is recorded net in the consolidated statement of income. Because these amounts offset each other, there was no impact on other operating income in each of 2013, 2012, and 2011.

	The Company evaluates and establishes an estimated reserve for credit and other risks associated with off-balance-sheet positions based upon historical losses, expected performance under these arrangements and current trends in the economy. The Company did not recognize any expense in other operating expenses within the non-interest expense in the consolidated statement of income during 2013 for credit losses on off-balance-sheet exposure as compared to $0.1 million recorded in 2012 and $1.8 million in 2011. As of December 31, 2013 and 2012 the reserve for off-balance sheet exposure was $1.0 million and $1.6 million, respectively.
	13. BALANCE SHEET OFFSETTING
	Certain financial instrument related assets and liabilities may be eligible for offset on the consolidated balance sheet because they are subject to master netting agreements or similar agreements. However, the Company does not elect to offset such arrangements on the consolidated financial statements.
	The Company enters into interest rate swap agreements with customers and financial institution counterparties. For additional detail regarding interest rate swap agreements refer to Footnote 12 within this section. In the event of default on, or termination of, any one contract, both parties have the right to net settle multiple contracts. Also, certain interest rate swap agreements may require the Company to receive or pledge cash collateral based on the contract provisions.
	The Company also enters into agreements to sell securities subject to an obligation to repurchase the same or similar securities, referred to as repurchase agreements on the consolidated balance sheet. Under these agreements, the Company may transfer legal control over the assets but still retain effective control through an agreement that both entitles and obligates the Company to repurchase the assets. The obligation to repurchase the securities is reflected as a liability in the Company’s consolidated balance sheet, while the securities underlying the repurchase agreements remain in the respective investment securities account, therefore there is no offsetting or netting of the investment securities assets with the repurchase agreement liabilities.

FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS	'
	14.  FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS
	In general, fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, which is not adjusted for transaction costs. Accounting guidelines establish a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted, quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:
	Basis of Fair Value Measurement:
	Level 1 - Unadjusted, quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
	Level 2 - Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and
	Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity).
	A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
	The types of instruments whose value is based on quoted market prices in active markets include most U.S. Treasury securities, liquid mortgage products, active listed equities and most money market securities. Such instruments are generally classified within Level 1 of the fair value hierarchy.  The Company does not adjust the quoted price for such instruments.
	The types of instruments whose value is based on quoted prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency include most U.S. Government agency securities, state and municipal bonds, mortgage-backed securities, collateralized mortgage obligations, and corporate securities. Such instruments are generally classified within Level 2 of the fair value hierarchy and their fair values are determined as follows:
	•	The markets for U.S. Government agency securities are active, but the exact (cusip) securities owned by the Company are traded thinly or infrequently. Therefore, the price for these securities is determined by reference to transactions in securities with similar yields, maturities and other features (matrix priced).
	•	State and municipal bonds owned by the Company are traded thinly or infrequently, and as a result the fair value is estimated in reference to securities with similar yields, credit ratings, maturities, and in consideration of any prepayment assumptions obtained from market data.
	•	Collateralized mortgage obligations and mortgage-backed securities are generally unique securities whose fair value is estimated using market information for new issues and adjusting for the features of a particular security by applying assumptions for prepayments, pricing spreads, yields and credit ratings.
	•	Certain corporate securities owned by the Company are traded thinly or infrequently. Therefore, the fair value of these securities is determined by reference to transactions in other issues of these securities with similar yields and features.
	14.  FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS - Continued
	Level 3 classification is for positions that are not traded in active markets or are subject to transfer restrictions. Valuations are adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate is used.  Management’s best estimate consists of both internal and external support on certain Level 3 investments.  Internal cash flow models using a present value formula along with indicative exit pricing obtained from broker/dealers are used to fair value Level 3 investments.  Management changes Level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying investment or comparable entities, subsequent rounds of financing, recapitalizations and other transactions across the capital structure, offerings in the equity or debt markets, and changes in financial ratios or cash flows. Fair values for securities classified within Level 3 are determined as follows:
	•	Certain corporate securities owned by the Company are not traded in active markets and prices for securities with similar features are unavailable. The fair value for each security is estimated in reference to benchmark transactions by security type based upon yields, credit spreads and option features.
	•	Certain marketable equity securities which are not subject to ownership restrictions but are traded thinly on exchanges or over-the-counter. As a result, prices are not available on a consistent basis from published sources, and, therefore, additional quotations from brokers may be obtained. Additionally considered indications of pricing include subsequent financing rounds or pending transactions. The reported fair value is based upon the Company’s judgment with respect to the information it is able to reliably obtain.
	The Company utilizes a third-party service provider to assist with investment security pricing. The Company evaluates the pricing results by periodically reviewing the service provider's practices and procedures. Additionally, each quarter the Company independently validates the pricing results of the third-party service provider by obtaining independent prices from other sources and evaluating discrepancies to established tolerances for each security type. The Company also investigates pricing outliers by security class, and performs a review of unchanged security prices.
	Interest rate swap agreements are measured by alternative pricing sources with reasonable levels of price transparency in markets that are not active.  Based on the complex nature of interest rate swap agreements, the markets these instruments trade in are not as efficient and are less liquid than that of the Level 1 markets.  These markets do however have comparable, observable inputs in which an alternative pricing source values these assets to arrive at a fair value.  These characteristics classify interest rate swap agreements as Level 2 measurements.
	The Company has the option to measure eligible financial assets, financial liabilities and Company commitments at fair value (i.e. the fair value option), on an instrument-by-instrument basis. The election to use the fair value option is available when an entity first recognizes a financial asset or liability or upon entering into a Company commitment. Subsequent changes in fair value must be recorded in earnings.
	Specifically, for asset/liability management purposes, the fair value option was applied to the Company’s only fixed rate subordinated debenture liability, which was redeemed by the Company during the first quarter of 2013. Upon redemption, the Company recognized a gain of $2.1 million in non-interest income for the reversal of the cumulative change in fair value previously recognized in earnings. For the twelve months ended December 31, 2012, non-interest income included a gain of $0.7 million for the change in fair value.

The following table sets forth the Company’s financial assets subject to fair value adjustments (impairment) on a non-recurring basis. Assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

OREO and other repossessed assets	—		—		3,029			3,029
Fair value for loans held-for-sale is estimated based upon available market data for mortgage-backed securities with similar interest rates and maturities.  Lower of cost or estimated fair value write-downs recorded on loans held-for-sale were zero as of December 31, 2013 and December 31, 2012.
The recorded investment in impaired loans totaled $57.7 million with a specific reserve of $8.3 million at December 31, 2013, compared to $56.2 million with a specific reserve of $3.1 million at December 31, 2012. Fair value for impaired loans is measured primarily on the value of the collateral securing these loans, less estimated costs to sell, or the present value of estimated cash flows discounted at the loan’s original effective interest rate.  Appraised values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and client’s business.
Fair value for OREO and other repossessed assets is estimated based upon its appraised value less costs to sell. Additional write-downs of $0.1 million and $0.3 million were included in the period-ending OREO and other repossessed assets balance at December 31, 2013 and December 31, 2012, respectively.
In addition to financial instruments recorded at fair value in the Company’s financial statements, disclosure of the estimated fair value of all of an entity’s assets and liabilities considered to be financial instruments is also required.  For the Company, as for most financial institutions, the majority of its assets and liabilities are considered to be financial instruments. However, certain instruments lack an available trading market as characterized by a willing buyer and willing seller engaging in an exchange transaction.  Also, it is the Company’s general practice and intent to hold its financial instruments to maturity and to not engage in trading or sales activities, other than mortgage loans held-for-sale.  Fair values have been estimated using data that management considered the best available and estimation methodologies deemed suitable for the pertinent category of financial instrument.

The fair value of cash and cash equivalents has been estimated to equal the carrying amounts due to the short-term nature of these instruments.  Therefore, cash and cash equivalents are classified within Level 1 of the fair value hierarchy.
The fair value of investment securities held-to-maturity has been estimated in a similar fashion to similar securities categorized as available-for-sale.  Held-to-maturity securities include state and municipal bonds, collateralized mortgage obligations and mortgage-backed securities.  These instruments are classified within Level 2 of the fair value hierarchy.
The fair value of the loan portfolio has been estimated using a discounted cash flow methodology based upon prevailing market interest rates relative to the portfolios’ effective interest rate which includes assumptions concerning prepayment rates and net credit losses.  The loan portfolio is classified within Level 3 of the fair value hierarchy.
The fair value of non-interest bearing demand deposits has been estimated to equal the carrying amount, which is assumed to be the amount payable on demand at the balance sheet date and therefore are classified within Level 1 of the fair value hierarchy.
The fair value of interest bearing deposits excludes deposits with stated maturities and is based on the assumption that the exit value of the instruments would be funded with like instruments by principal market participants.  These instruments are classified within Level 2 of the fair value hierarchy.
The fair value of deposits with stated maturities is estimated at the present value of associated cash flows using contractual maturities and market interest rates.  These instruments are classified within Level 2 of the fair value hierarchy.
14.  FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS - Continued
The fair value of customer repurchase agreements has been estimated at the present value of associated cash flows using contractual maturities and market interest rates for each instrument.  These instruments are classified within Level 2 of the fair value hierarchy.
The fair value of repurchase agreements is determined based on current market rates for similar borrowings, as well as a further calculation for valuing the optionality of the conversion features in certain of the instruments.  These instruments are classified within Level 2 of the fair value hierarchy.
The fair value of FHLB advances is determined based on current market rates for similar borrowings with similar credit ratings, as well as a further calculation for valuing the optionality of the conversion features in certain of the instruments.  These instruments are classified within Level 2 of the fair value hierarchy.
The fair value option was elected for the Company’s fixed rate subordinated debenture, and the fair value was measured on an unadjusted, quoted price for the traded assets (formerly Nasdaq: “NPBCO”) and as such was classified within Level 1 of the fair value hierarchy. The fair value of this instrument was $67.3 million at December 31, 2012 and zero at December 31, 2013 due to its redemption on March 7, 2013. Subordinated debentures that have floating interest rates based upon LIBOR are callable at any time and, due to the call feature, the fair value is estimated to equal the par amount. These instruments are classified within Level 2 of the fair value hierarchy.

REGULATORY MATTERS	'
	15.  REGULATORY MATTERS
	National Penn and National Penn Bank are subject to regulations of certain federal and state agencies, and undergo periodic examinations by such regulatory authorities.
	National Penn Bank’s capital amount and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulations to ensure capital adequacy require National Penn Bank and the Company to maintain minimum amounts and ratios (set forth in the following table) of total and Tier I capital (as defined in the regulations) to risk-weighted assets, and of Tier I capital to average assets. Management believes, as of December 31, 2013, that National Penn Bank and the Company met all capital adequacy requirements to which they are subject.
	National Penn Bank is required to maintain average reserve balances with the Federal Reserve Bank.  The required reserve was $22.9 million at December 31, 2013. The average amount of these balances for the year ended December 31, 2013 was approximately $46.3 million.
	The following tables summarize National Penn's and National Penn Bank’s regulatory capital.

BENEFIT PLANS	'
	16. BENEFIT PLANS
	Capital Accumulation Plan
	The Company has a contributory capital accumulation plan under Section 401(k) of the Internal Revenue Code of 1986, as amended.  Under the plan, eligible participants may contribute a minimum of 1% of eligible earnings up to a maximum of the respective annual IRS allowable contribution each year.
	Under the Capital Accumulation Plan:
	•	Persons become eligible for participation on the first day of the month following 30 days of employment.
	•	For newly-eligible employees, enrollment at 3% of base compensation is automatic and increases 1% on January 2nd of each year, until reaching 7% of base compensation, subject to an “opt-out” procedure.
	•	There is a discretionary profit sharing account, which utilizes the same performance targets as National Penn’s annual Executive Incentive Plan and Management Incentive Plan.
	•	The Company’s “match” is 50% of the first 7% of an employee’s compensation contributed to the Plan.
	Matching contributions to the plan, including discretionary profit sharing, included in salaries, wages and employee benefit expenses were $3.8 million, $3.9 million, and $3.9 million, for the years ended December 31, 2013, 2012, and 2011, respectively.
	Pension Plan
	The Company has a curtailed, non-contributory defined benefit pension plan (National Penn Bancshares, Inc. Employee Pension Plan) covering substantially all employees of the Company and its subsidiaries employed as of January 1, 2009.  The Company-sponsored pension plan provides retirement benefits under pension trust agreements based on years of service. Prior to April 1, 2006, benefits are based on the average of the employee compensation during the highest five consecutive years during the last ten consecutive years of employment. Beginning on April 1, 2006, eligible compensation was limited to $50,000 per year.  The Company did not make a contribution in 2013 because the plan’s funding credit balance was applied toward reducing the contribution requirement.
	On February 12, 2010, the Company curtailed its pension plan effective March 31, 2010, whereby no additional service will accumulate for vested participants after March 31, 2010. Unvested participants still have the opportunity to meet the five year vesting requirement to earn a benefit.

	Plan Assets
	The financial statements of the Company's pension plan are prepared on the accrual basis of accounting. Interest income is recorded on the accrual basis, and dividends are recorded on the ex-dividend date. The pension plan's investments are stated at fair value, and purchases and sales of securities are recorded on the trade date. To determine the fair value of plan assets, the pension plan utilizes the fair value hierarchy as described in detail in Footnote 14 Fair Value Measurements and Fair Value of Financial Instruments. The fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Investments in interest bearing cash are stated at cost, which approximates fair value. The fair values of money market and mutual funds are based on quoted net asset values of the shares held by the plan on the valuation date. The fair values of common stocks and U.S. Government obligations are valued at the closing price reported in active markets in which the individual securities are traded. The plan does not have any assets in the Company’s stock. Actively traded corporate bonds and notes are valued based on quoted prices. U.S. Government agency obligations are valued based on yields currently available on comparable securities of issuers with similar credit ratings. The plan does not have any Level 3 investments.

Deferred Compensation Arrangements
The Company has established deferred compensation arrangements for certain retired executive officers that provide for annual payments for fifteen years following retirement. The Company’s liabilities under these arrangements were accrued from the commencement of the agreements over the participant’s service periods.  The expense related to these deferred compensation arrangements is recorded in salaries, wages and employee benefits expense in the consolidated statement of income.
The Company has obtained, through its acquisitions, several non-qualified, unfunded contracts for certain executive officers.  These contracts supplement the benefit these executive officers will receive under the Company’s qualified retirement plans. Certain contracts also provide for survivor and other termination benefits.  The expense recorded in connection with these contracts was $0.8 million for December 31, 2013 and $1.1 million for December 31, 2012, and $1.4 million for December 31, 2011.  The Company is the beneficiary of life insurance policies that are intended to fund a portion of the contracts, which had a cash surrender value of $23.5 million as of December 31, 2013.

SHARE BASED COMPENSATION	'
	17. SHARE-BASED COMPENSATION
	The Company, through its Compensation Committee of the Board of Directors, offers equity compensation to employees and non-employee directors of National Penn, National Penn Bank and other National Penn subsidiaries in the form of share-based awards.  Stock options, restricted stock awards (“RSAs”), and restricted stock units (“RSUs”) vest over time, upon the satisfaction of established performance criteria, or both.
	The Company believes such awards better align the interests of its employees and non-employee directors with those of its shareholders. Option awards are granted with an exercise price at least equal to the market price of the Company’s stock at the date of grant. Option and other share-based awards vest at such times as are determined by the Compensation Committee of the Board of Directors at the time of grant, but not before one year from the date of grant or later than five years from the date of grant.  The options have a maximum term of ten years for incentive stock options or ten years, one month for non-qualified stock options.
	The fair value of RSAs and RSUs is estimated based on the price of the Company’s common stock on the date of grant.  Compensation cost is measured ratably over the vesting period of the awards and reversed for awards which are forfeited due to unfulfilled service or performance criteria.
	Vesting of share-based awards is immediately accelerated in the event of a change-in-control; in the event the recipient’s service terminates due to death, disability or retirement (including a voluntary termination of employment at age 60 or more); or in the event of an involuntary termination of employment not for cause.
	Awards are currently granted under the Long-Term Incentive Compensation Plan, approved by shareholders in April 2005 (“2005 Plan”) and expiring November 30, 2014.  Under the terms of the 2005 Plan, a total of 5,304,500 shares of common stock have been made available for option, restricted stock, or other share-based awards. As of December 31, 2013, approximately 1.5 million shares remain available for issuance under the terms of the 2005 Plan.
	17. SHARE-BASED COMPENSATION - Continued
	Prior to the adoption of the 2005 Plan, the Company maintained other employee stock compensation plans ("Previous Company Plans"). A total of 5,048,577 shares of common stock were made available for option or restricted stock awards. At December 31, 2013, approximately 0.5 million shares remain outstanding from the Previous Company Plans. In addition to the Previous Company Plans, the Company issued 3,022,185 substitute stock options as a result of acquisitions made in 2008, of which, approximately 1.7 million options were outstanding at December 31, 2013.

	The Company believes that it is more likely than not that the deferred tax assets will be realized based upon estimates of taxable income and tax planning strategies; as a result, no valuation allowance was recorded as of December 31, 2013 or 2012. The Company has adjusted its beginning and ending deferred tax assets and liabilities for prior acquisitions and reclassifications of tax reserves.
	As of December 31, 2013, the Company’s deferred tax asset included a net operating loss (“NOL”) carry forward of $0.7 million which expires in 12 years and is limited annually due to an ownership change that occurred, as defined by Section 382 of the Internal Revenue Code, from prior acquisitions. The Company anticipates fully utilizing its NOL prior to its statutory expiration dates. The Company has the additional following carryover items: (1) low income housing credits of $0.5 million that will begin to expire in 2030 if not utilized; and (2) an alternative minimum tax credit of $30.6 million which has an indefinite life.
	Uncertain Tax Positions

Segment Reporting [Abstract]	'
SEGMENT REPORTING	'
	20. SEGMENT INFORMATION
	The Company’s operating segments, which are evaluated regularly by the Chief Executive Officer to decide how to allocate and assess resources and performance, are “Community Banking” and “Other.” The Company determines its segments based primarily upon product and service offerings and through the types of income generated.
	The Company’s community banking segment consists of commercial and retail banking. The community banking business segment is managed as a single strategic unit, which generates revenue from a variety of products and services it provides. Examples of products and services provided include commercial business loans, commercial real estate loans, residential mortgages and other consumer loans, and deposit and cash management services. Both commercial and retail banking are dependent upon deposits and various borrowings to manage interest rate and credit risk.
	The Company has also identified several other operating segments. These non-reportable segments include National Penn Wealth Management, N.A., National Penn Capital Advisors, Inc., National Penn Insurance Services Group, Inc., and the parent bank holding company and are included in the “Other” category. These operating segments do not have similar characteristics to the community banking operations and do not individually or in the aggregate meet the quantitative thresholds requiring separate disclosure. The operating segments in the “Other” category earn revenues primarily through the generation of fee income and are also aggregated based on their similar economic characteristics, products and services, type or class of customer, methods used to distribute products and services and/or nature of their regulatory environment. The identified segments reflect the manner in which financial information is currently evaluated by management. The accounting policies, used in this disclosure of operating segments, are the same as those described in the Footnote 1 "Summary of Significant Accounting Policies" within this section.
	Reportable segment-specific information and reconciliation to consolidated financial information is as follows:

SUMMARY_OF_SIGNIFICANT_ACCOUNT1

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
NATURE OF OPERATIONS	'
	Nature of Operations
	National Penn Bancshares, Inc. (the “Company” or “National Penn”), primarily through its national bank subsidiary, National Penn Bank (“NPB”) serves residents and businesses primarily in eastern and central Pennsylvania.  NPB, which has 120 retail branch office locations (119 in Pennsylvania and one in Cecil County, Maryland), is a locally managed community bank providing commercial banking products, primarily loans and deposits.
	The Company’s financial service units consist of an array of investment, insurance and employee benefit services through its non-bank subsidiaries. National Penn’s financial services affiliates consist of National Penn Wealth Management, N.A., including its National Penn Investors Trust Company division; National Penn Capital Advisors, Inc.; Institutional Advisors, LLC; and National Penn Insurance Services Group, Inc., including its Higgins Insurance and Caruso Benefits divisions.
	The Company and its operating subsidiaries compete for market share in the communities they serve with other bank holding companies, community banks, thrift institutions and other non-bank financial organizations, such as mutual fund companies, insurance companies and brokerage companies.
	The Company and its operating subsidiaries are subject to regulations of certain state and federal agencies.  These regulatory agencies periodically examine the Company and its subsidiaries for adherence to laws and regulations.  As a consequence, the cost of doing business may be affected.
BASIS OF FINANCIAL STATEMENT PRESENTATION	'
	Basis of Financial Statement Presentation
	The accounting policies followed by the Company conform with accounting principles generally accepted in the United States of America (“GAAP”) and predominant practice within the banking industry.
CONSOLIDATION POLICY	'
	The consolidated financial statements include the accounts of the Company and the Company’s direct and indirect wholly owned subsidiaries.  The Company’s unconsolidated subsidiaries, representing investments in joint ventures, and other entities are accounted for using the equity method of accounting.  All material inter-company balances have been eliminated.
RECLASSIFICATIONS	'
	Reclassifications
	Certain prior year amounts have been reclassified to conform to current period classifications. These reclassifications did not have a material impact on our consolidated financial condition or results of operations.
USE OF ESTIMATES	'
	Use of Estimates
	In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the balance sheets, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	The principal estimates that are susceptible to significant change in the near term relate to the allowance for loan losses, goodwill and intangible assets, income taxes, and other-than-temporary impairment. Management’s practice is to retain supporting files for all accounting entries made, but in particular to organize, support and prepare clarifying memoranda for items in the financial statements requiring significant judgment.
BUSINESS COMBINATIONS	'
	Business Combinations
	At the date of acquisition the Company records the net assets of acquired companies on the consolidated balance sheet at their estimated fair value, and goodwill is recognized for the excess of the purchase price over the estimated fair value of acquired net assets. The results of operations for acquired companies are included in the Company’s consolidated statement of income beginning at the acquisition date. Expenses arising from acquisition activities are recorded in the consolidated statement of income during the period incurred.
REVENUE RECOGNITION	'
	Revenue Recognition
	The Company recognizes revenue in the consolidated statement of income as it is earned and when collectability is reasonably assured. The primary source of revenue is interest income from interest earning assets, which is recognized on the accrual basis of accounting using the effective interest method. The recognition of revenues from interest earning assets is based upon formulas from underlying loan agreements, securities contracts or other similar contracts. Non-interest income is recognized on the accrual basis of accounting as services are provided or as transactions occur. Non-interest income includes fees from wealth management services, deposit accounts, sales of insurance products, cash management and electronic banking services, mortgage banking activities, standby letters of credit and financial guarantees, and other miscellaneous services and transactions.
ADVERTISING COSTS	'
	Advertising Costs
	Advertising costs are recorded in the period they are incurred within other operating expenses in non-interest expense in the consolidated statement of income. Advertising expense was $5.5 million, $5.6 million, and $5.9 million for the years ended December 31, 2013, 2012 and 2011, respectively.
CASH AND CASH EQUIVALENTS	'
	Cash and Cash Equivalents
	Cash and due from banks and interest bearing deposits with banks comprise “cash and cash equivalents” on the consolidated balance sheet and statement of cash flows.  Cash held on deposit with other financial institutions is in excess of FDIC insurance limits.
RESTRICTIONS ON CASH IN CASH AND DUE FOM BANKS	'
	The Company is required to maintain cash reserves that are considered restrictions on cash and due from banks shown on our consolidated balance sheet. These restrictions consist of required reserves with the Federal Reserve Bank related to our deposit liabilities and cash collateral related to international letters of credit and interest rate swaps with financial institution counterparties. Total restricted cash was $52.4 million and $88.7 million for the years ended December 31, 2013 and 2012, respectively.
INVESTMENT SECURITIES AND OTHER INVESTMENTS	'
	Investment Securities and Other Investments
	Investment securities which are held for indefinite periods of time, which management intends to use as part of its asset/liability strategy, or which may be sold in response to changes in interest rates, changes in prepayment risk, increases in capital requirements, or other similar factors, are classified as available-for-sale and are recorded at their estimated fair value on the consolidated balance sheet. Changes in unrealized gains and losses for such securities, net of tax, are reported in accumulated other comprehensive income as a separate component of shareholders’ equity and are excluded from the determination of net income. Investment securities which have stated maturities for which the Company has the intent and ability to hold until the maturity date are classified as held-to-maturity and are recorded at amortized cost on the consolidated balance sheet.
	Interest from debt securities is recognized in interest income inclusive of adjustments for amortization of purchase premiums and accretion of purchase discounts using the interest method. Dividends from investments in equity securities are accrued in interest income in the consolidated statement of income when they are declared. Gains or losses from the disposition of investment securities are recognized at the trade date as non-interest income in the consolidated statement of income, based on the net proceeds and cost of the securities sold, adjusted for amortization of premiums and accretion of discounts, using the specific identification method.
	When the fair value of an investment security is less than the carrying value, the security is considered to be impaired, and as such the Company reviews the security for the presence of other-than-temporary impairment ("OTTI"). This analysis is performed at least quarterly, and includes the consideration of numerous factors including the time period for which the fair value has been less than the carrying value, curtailment or suspension of dividends or cash flows, deterioration of financial performance or the creditworthiness of the issuer, performance of any underlying collateral, and negative trends in a particular industry or sector. The conclusion as to whether OTTI exists for an investment security is ultimately based upon the Company’s evaluation of the investment’s recoverability above its carrying value and its timing. In addition, the Company considers whether it plans to sell an investment security and whether it may be required to sell the security prior to recovery of its carrying value.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	When the Company concludes an investment security is other-than-temporarily impaired, a loss for the difference between the investment security’s carrying value and the fair value is recognized as a reduction to non-interest income in the consolidated statement of income. For an investment in a debt security, if the Company does not intend to sell the investment security and concludes that it is not more likely than not it will be required to sell the security before recovering the carrying value, which may be maturity, the OTTI charge is separated into the "credit" and "other" components. The "other" component of the OTTI is included in other comprehensive income, net of the tax effect, and the "credit" component of the OTTI is included in the consolidated statement of income as a reduction to non-interest income.
COST METHOD INVESTMENTS	'
	Other investments are comprised of Federal Home Loan Bank ("FHLB") of Pittsburgh stock and Federal Reserve Bank stock. Federal Reserve Bank stock is an equity interest in the Philadelphia Federal Reserve Bank that is required of member banks. The required subscription for Federal Reserve Bank stock is equal to 6% of National Penn Bank’s capital and surplus. The stock is not transferable and additional purchases or cancellations of the stock are transacted directly with the Federal Reserve Bank of Philadelphia. FHLB stock is an equity interest that can be sold to the issuing FHLB, to other FHLBs, or to other member banks at its par value. Because ownership of these securities is restricted, they do not have a readily determinable fair value. As such, the Company’s other investments are recorded at cost or par value and are evaluated for impairment each reporting period by considering the ultimate recoverability of the investment rather than temporary declines in value.  The Company’s evaluation primarily includes an evaluation of liquidity, capitalization, operating performance, commitments, and regulatory or legislative events.
LOANS AND LEASES	'
	Loans and Leases
	Loans that management has the intent to hold for the foreseeable future or until maturity or payoff are considered held for investment and are reported at the amount of unpaid principal, net of unearned income, unamortized deferred fees and origination costs, commitment fees, and premiums or discounts on acquired loans. The Company also estimates an allowance for loan losses, which is netted from the carrying amount of loans presented on the consolidated balance sheet. Interest on loans is calculated based upon the principal amount outstanding. Net deferred fees on Company originated loans, consisting of origination and commitment fees and direct loan origination costs, are amortized over the contractual life of the related loans using the interest method, which results in an adjustment of the related loan’s yield. Premiums or discounts resulting from loans acquired are included or netted with the balance of unpaid principal on the consolidated balance sheet and are also deferred and amortized over the contractual life of the loan using the interest method.
	Loans are placed on non-accrual status and accrual of interest is suspended on a loan when management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that collection of all contractually required payments is no longer probable. When a loan is on non-accrual status, payments are applied in their entirety to principal. If a borrower’s financial condition improves to the point where management believes that collection of the remaining principal and interest is probable, management may restore the loan to accrual status, at which time payments received are applied to both principal and interest and recognition of interest income continues. Generally, loans are placed on non-accrual status when they reach 90 days past due based on the contractual terms of the loan agreement.
	Direct financing leases are carried at the aggregate of the lease payments plus the estimated residual value of the leased property, net of unearned income and deferred initial direct costs. Interest income on leases is recognized using the interest method over the lease term, which incorporates amortization of deferred initial direct costs as an adjustment to the lease’s yield. Residual values for leases are reviewed for impairment at least annually based upon historical performance, independent appraisals, and industry data. Valuation adjustments to residual values are included in other operating expenses within non-interest expense in the consolidated statement of income. Gains or losses from the sale of leased assets are also included in other operating income within non-interest income in the statement of income.
	Equipment underlying leases to customers for which a sale to the lessee is not implied or imminent is reported on the consolidated balance sheet within premises and equipment and is depreciated over its useful life. In the event that the lessee fails to meet a contractual leasing obligation, the remaining carrying value is considered a non-performing asset, including any underlying equipment which may be repossessed.
LOANS HELD FOR SALE	'
	Loans Held-For-Sale
	Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value on the consolidated balance sheet, and these loans are traditionally sold servicing released. The fair value of loans held-for-sale is estimated based upon the contractually agreed upon sales price to investors. Write-downs to fair value, if any, are reflected through a valuation allowance netted from the cost basis of the loans on the consolidated balance sheet and a related expense recorded as a reduction to mortgage banking income in the consolidated statement of income. At disposition, the difference between the net proceeds received and the carrying value of the loan is recorded as a gain or loss within mortgage banking income in the consolidated statement of income. Estimated credit losses, if any, on loans transferred to held-for-sale, which management previously intended to hold for investment, are charged to the allowance at the time of transfer. Non-credit related losses, if any, or subsequent gains or losses upon disposition are recorded in other operating expenses within non-interest expense on the consolidated statement of income. Valuations of non-mortgage loans transferred to held-for-sale are performed on an individual basis.
NONPERFORMING ASSETS	'
	Non-Performing Assets
	Assets which are otherwise considered earning assets may cease to perform according to their original terms and become non-performing assets. The Company’s non-performing assets consist of non-accrual loans, loans defined as troubled debt restructurings, and other real estate owned. On an ongoing basis, the Company monitors economic conditions and reviews borrower financial results, collateral values, and compliance with payment terms and covenant requirements in order to identify problems in loan relationships. All problem loans are reviewed regularly for impairment. When management believes that the collection of all or a portion of principal and interest is no longer probable, the accrual of interest is suspended, and payments for interest are applied to principal until the Company determines that all remaining principal and interest can be recovered. This may occur at any time regardless of delinquency status, however, loans 90 days or more past due are reviewed monthly to determine whether interest accrual should continue. Loans for which the accrual of interest has been suspended are categorized as non-accrual loans.
	Through negotiations with a borrower, the Company may restructure a loan prior to or at its contractual maturity. Modification of a loan’s terms constitutes a troubled debt restructuring ("TDR") if the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession that it would not otherwise consider. The Company restructures loans in an attempt to preserve or improve the economic recovery of principal and/or interest due from a borrower. Not all modifications of loan terms automatically result in a TDR, only modifications which are concessions (terms not otherwise attainable) to a borrower experiencing financial distress constitute TDRs. TDRs are disclosed as restructured loans. TDRs and non-accrual loans comprise the Company’s impaired loans which are evaluated individually for purposes of determining the allowance for loan losses.
	Other real estate owned ("OREO") results from the acquisition of real estate through foreclosure, abandonment, or conveyance of deed in lieu of foreclosure of a loan. OREO is carried on the consolidated balance sheet within OREO and other repossessed assets at the estimated fair value of the real estate less expected costs to sell at the acquisition date. Any loss upon reclassification from loans to OREO is recognized as a charge to the allowance for loan losses. During the holding period, OREO continues to be measured at the lower of its carrying amount or estimated fair value less costs to sell, and any valuation adjustment and gains or losses upon disposition are recognized within other operating income within non-interest income in the consolidated statement of income. OREO is evaluated individually rather than as a group, unless the circumstances render the group measurement to be a more appropriate basis as determined by management.
SIGNIFICANT CONCENTRATIONS OF CREDIT RISK	'
	Significant Concentrations of Credit Risk
	Most of the Company’s activities are with customers located throughout eastern and central Pennsylvania. The Company’s commercial portfolio has a concentration in loans to commercial real estate investors and developers as defined by regulation. There are numerous risks associated with commercial loans that could impact the borrower’s ability to repay on a timely basis. They include, but are not limited to: the owner’s business expertise; changes in local, national, and in some cases international economies; competition; governmental regulation; and the general financial stability of the borrowing entity.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	The Company attempts to mitigate these risks by completing an analysis of the borrower’s business and industry history, the borrower’s financial position, as well as that of the business owner. The Company will also require the borrower to periodically provide financial information on the operation of the business over the life of the loan. In addition, most commercial loans are secured by assets of the business or those of the business owner, which can be liquidated if the borrower defaults, along with the personal surety of the business owner.
ALLOWANCE FOR LOAN AND LEASE LOSSES	'
	Allowance for Loan Losses
	Management conducts an analysis of the loan portfolio to estimate the amount of the allowance for loan losses (allowance) which is adequate to absorb inherent losses on existing loans. The allowance is established through a provision for loan losses charged as an expense in the consolidated statement of income. Loans are charged-off to the allowance when management believes that the collectability of the principal is less than probable and sufficient information exists to make a reasonable estimate of the inherent loss or a loss event has been confirmed.
	The evaluation of the adequacy of the allowance includes an analysis of individual loans and groups of homogeneous loans. Loans in the portfolio are segregated by risk characteristics. This is primarily accomplished by separating loan types as well as loan risk designations including, but not limited to: loans classified as Substandard or Doubtful as defined by regulation; loans criticized internally or designated as Special Mention; and loans specifically identified by management as impaired.
	The analysis of individual loans and analytical processes performed by management in the calculation of the allowance is ongoing, and adjustments may be made based on the assessment of internal and external influences on credit quality. Those influences include, but are not limited to: unemployment, delinquency and non-accrual rates, trends in loan volume, portfolio growth, portfolio concentrations, Board and loan review oversight, exceptions to policy, competition and other external factors, and/or changes in value of collateral dependent loans.
	The Company evaluates economic conditions and reviews borrower financial results, collateral values, and compliance with contractual payment terms and covenant requirements in order to monitor loan relationships. A classified loan is one which is paying as agreed, but based upon management’s analysis is determined to be inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. All classified loans are evaluated to determine whether they are non-performing or whether it is probable they will become non-performing, based on facts and circumstances.
	When management believes that the collection of all or a portion of principal and interest is no longer probable, the loan is placed on non-performing status, accrual of interest is suspended, and payments for interest are applied to principal until the Company determines that all remaining principal and interest can be recovered. This may occur at any time regardless of delinquency, however, loans 90 days or more past due are reviewed monthly to determine whether the accrual of interest should continue. Because all or a portion of the contractual cash flows are not expected to be collected in accordance with the underlying loan agreements, the loan is considered to be impaired, and the Company estimates and records impairment based upon the present value of the expected cash flows it will be able to collect.
	Values of collateral securing commercial loans are confirmed through regular updates and reviews, but at a minimum are updated every twelve months for all loans designated as Special Mention or Classified, every six to nine months for land loans. During the period between appraisal order and completion, management makes an estimate of collateral values based on available market information and other recent appraisal results.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	Specific Reserves
	Specific reserves are an estimation of losses specific to individual impaired loans. All non-performing and restructured loans are evaluated to determine the amount of specific reserve or the required charge-off, if any, to reduce the current carrying value of the individual loan to its net realizable value based on an analysis of the available sources of repayment, including liquidation of collateral. The net realizable value is estimated as the present value of expected future cash flows discounted at the loan’s effective interest rate, the observable market price if the loan is expected to be sold, or, if collateral dependent, the estimated fair value of the collateral less costs to sell based on recent appraisals. A specific reserve may be established instead of a charge-off when sufficient information exists to make a reasonable estimate of the loss but where a loss event has not yet been confirmed. While every impaired loan is individually evaluated, not every impaired loan requires a specific reserve. Specific reserves fluctuate based on changes in the collectability of underlying loans and any previously recorded charge-offs. A confirmed loss event could be a payment delinquency of typically 90 days or greater, bankruptcy, fraud, death, or defunct status of a business, project or development. Impaired loans are excluded from the calculation of allocated reserves as described below.
	Charge-offs
	Commercial and industrial loans are charged-off in whole or in part when they become 90 or more days delinquent based upon the terms of the underlying loan contract and when full collectability of the principal balance is no longer probable. Because all or a portion of the contractual cash flows are not expected to be collected, the loan is considered to be impaired, and the Company estimates and records impairment based upon the present value of the expected cash flows it will be able to collect. Loans in bankruptcy and loans to defunct businesses are charged-off to the estimated fair value of collateral, less costs to sell.
	Commercial real estate loans are charged-off in whole or in part when they become 90 or more days delinquent based upon the terms of the underlying loan contract and when a collateral deficiency exists. Because all or a portion of the contractual cash flows are not expected to be collected, the loan is considered to be impaired, and the Company estimates and records impairment based upon the expected cash flows it will be able to collect, which is generally from the liquidation of the pledged collateral. Loans in bankruptcy and loans to defunct projects or development businesses are charged-off to the estimated fair value of collateral, less costs to sell.
	Consumer loans are charged-off when they become non-performing, which is no later than when they become 90 days past due. At that time, the amount of the estimated collateral deficiency, if any, is charged-off for loans secured by collateral, all other loans are charged-off in full. Loans in which the borrower is in bankruptcy are charged-off within 60 days of receipt of notification of the bankruptcy filing or within the timeframes specified in policy, whichever is shorter, unless it can be established that repayment is likely to occur. Loans with collateral are charged-down to the estimated fair value of collateral, less costs to sell.
	Allocated Reserves
	Allocated reserves represent an allowance for groups of homogeneous loans which are similar in nature and as such are not individually evaluated for impairment. Allocated reserves are applied to both the non-criticized and criticized and classified portions of each portfolio. The Company segregates the loan portfolio into strata based upon risk characteristics which reflect the behavior and performance of the underlying loans.
	Classified and criticized loans are stratified based upon underlying loan types and characteristics and are separately evaluated to determine the amount of reserve considered adequate. Loss factors are based on the loan type, performance trends, portfolio characteristics, risk, and assigned ratings.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	For pass-rated loans, an estimate of inherent loss is made by applying portfolio-specific environmental and historical loss factors to the period-end balances of each loan category. Environmental factors are applied in addition to historical loss factors to reflect trends which management believes are not fully incorporated in historical net charge-off ratios. Environmental factors include: unemployment, delinquency and non-accrual rates, trends in loan volume and portfolio growth, portfolio concentrations, Board and loan review oversight, exceptions to policy, experience of management, competition and other external factors, and changes in the fair value of collateral dependent loans. A historical loss factor is generated using actual losses for the preceding twelve quarters from the current quarter end. The loss percentages are weighted to utilize the most relevant and current loss experience.
	Unallocated Reserve
	The unallocated reserve addresses inherent losses not included elsewhere in the allowance. It represents an element in the adequacy of the allowance given the nature of the calculation and the inherent imprecision and uncertainty as to estimated losses.
PREMISES AND EQUIPMENT	'
	Premises and Equipment
	Land is stated at cost. Buildings, equipment and leasehold improvements are stated at cost less accumulated depreciation and amortization which is generally computed on a straight-line basis over the estimated useful life of the asset. Leasehold improvements are amortized using the straight-line method over the lesser of the estimated economic life or the lease term. Depreciation and amortization expense for premises and equipment is included in premises and equipment expense in the consolidated statement of income.
	The Company leases certain premises and equipment under non-cancellable operating leases. Certain leases contain renewal options and rent escalation clauses calling for rent increases over the term of the lease. Rental expense for all leases which contain escalation clauses are accounted for on a straight-line basis over the lease term.
	Expenses for maintenance and repairs are recorded in premises and equipment expense in the consolidated statement of income as they are incurred.
ACCRUED INTEREST RECEIVABLE	'
	Accrued Interest Receivable
	The Company records interest income on interest earning assets on the accrual basis which results in the recognition of interest income recorded in the consolidated statement of income before it is received. The consolidated balance sheet includes the amount of interest earned on the accrual basis of accounting but not yet received as of the date presented. The balance is primarily comprised of interest earned on loans to customers and dividends and interest on investment securities.
BANK OWNED LIFE INSURANCE	'
	Bank Owned Life Insurance
	The Company invests in bank owned life insurance ("BOLI") policies that provide earnings to help cover the cost of employee benefit plans. The Company is the owner and beneficiary of the life insurance policies it purchased directly on a chosen group of employees or it obtained through acquisitions of other institutions that previously purchased the policies. The policies are carried on the Company’s consolidated balance sheet at their cash surrender value and are subject to regulatory capital requirements. The determination of the cash surrender value includes a full evaluation of the contractual terms of each policy and assumes the surrender of policies on an individual-life by individual-life basis. Additionally, the Company periodically reviews the creditworthiness of the insurance companies that have underwritten the policies. Earnings accruing to the Company are derived from the general account investments of the insurance companies. Increases in the net cash surrender value of BOLI policies and insurance proceeds received are not taxable and are recorded in non-interest income in the consolidated statement of income.
GOODWILL AND OTHER INTANGIBLE ASSETS	'
	Goodwill and Other Intangible Assets
	Goodwill is recognized for the excess of the purchase price over the estimated fair value of acquired net assets in a business combination. Goodwill is not amortized but is reviewed for potential impairment on at least an annual basis, which the Company performs during the second quarter of each year. The Company has the option of performing a qualitative assessment to determine whether it is more likely than not that the fair value of one of the Company’s identified reporting units is less than its carrying value. If the results of the qualitative assessment indicate the potential for impairment, the Company would perform the two-step goodwill impairment analysis.
	In performing the two-step goodwill impairment analysis, if necessary, the estimated fair value of each reporting unit is compared to its carrying value, inclusive of the goodwill assigned to it. If the carrying value of a reporting unit exceeds the estimated fair value, an indicator of goodwill impairment exists and a second step is performed to determine if any goodwill impairment exists. In the second step, the Company calculates the implied value of goodwill by emulating a business combination for each reporting unit. This step subtracts the estimated fair value of net assets in the reporting unit from the step one estimated fair value to determine the implied value of goodwill. If the implied value of goodwill exceeds the carrying value of goodwill allocated to the reporting unit, goodwill is not impaired, but if the implied value of goodwill is less than the carrying value of the goodwill allocated to the reporting unit, an impairment charge is recognized for the difference in the consolidated statement of income with a corresponding reduction to goodwill on the consolidated balance sheet. The Company’s business segments are its reporting units which are community banking and other for purposes of the goodwill impairment analysis.
	In performing its analysis of goodwill impairment, the Company makes significant judgments, particularly with respect to estimating the fair value of each reporting unit and if the second step is required, estimating the fair value of net assets. The Company evaluates each reporting unit and estimates a fair value as though it were an acquirer. The estimates utilize historical data, cash flows, and market and industry data specific to each reporting unit. Industry and market data is used to develop material assumptions such as transaction multiples, required rates of return, control premiums, transaction costs and synergies of a transaction, and capitalization.
	On an interim basis, the Company evaluates whether circumstances are present that could indicate potential impairment of its goodwill. These circumstances include, but are not limited to, prolonged trading value of the Company’s common stock relative to its book value, adverse changes in the business or legal climate, actions by regulators or loss of key personnel. When the Company determines that these or other circumstances are present, the Company tests the carrying value of goodwill for impairment at an interim date.
	Other intangible assets are specifically identified intangible assets created from a business combination. Core deposit intangibles represent the value of checking, savings and other acquired, low-cost deposits. Core deposit intangibles are amortized over the lesser of the estimated lives of deposit accounts or ten years on an accelerated basis. Decreases in deposit lives may result in increased amortization and/or an impairment charge. Other intangible assets also include customer lists and covenants not to compete. These assets are amortized over the lesser of their contractual life or estimated economic life on a straight-line basis.
UNCONSOLIDATED INVESTMENTS UNDER THE EQUITY METHOD	'
	Unconsolidated Investments Under the Equity Method
	The Company invests in partnerships and other non-consolidated businesses. These investments typically range from 20% ownership up to 50% and are accounted for using the equity method. The Company’s proportionate share of income or loss on equity method investments is recorded in non-interest income in the consolidated statement of income using the accrual basis of accounting. Cash received by the Company for dividends or distributions on these investments reduces the carrying value of the equity method investment on the consolidated balance sheet. These investments are reviewed at least annually for other-than-temporary declines below the investment’s carrying value. Consideration is given to a number of variables, including any expected tax credits or other similar benefits from each investment. Impairment charges are recorded as a reduction to the investment’s carrying value on the consolidated balance sheet and to non-interest income in the consolidated statement of income.
SECURITIES SOLD UNDER REPURCHASE AGREEMENTS	'
	Repurchase Agreements
	The Company’s repurchase agreements are secured borrowing transactions collateralized by investment securities. The Company sells investment securities to counterparties with an agreement to repurchase the exact or substantially the same securities at a specified date. On the trade date, the Company records a liability on the consolidated balance sheet for the amount for which securities will be subsequently reacquired, including accrued interest, based upon the contractual term of the transaction. Interest expense from repurchase agreements is recognized on the accrual basis of accounting in the consolidated statement of income.
	The securities underlying repurchase agreements are identified and disclosed as pledged for this purpose in the notes to the financial statements. The investment securities remain on the Company’s consolidated balance sheet and are accounted for consistent with the Company’s other investment securities available-for-sale. Repurchase agreements are satisfied by the payment of cash from the Company to the counterparty at which time the securities identified in the transaction are no longer considered pledged.
SUBORDINATED DEBENTURES	'
	Subordinated Debentures
	At the beginning of 2013, the Company had five established statutory business Trusts: NPB Capital Trust II, NPB Capital Trust III, NPB Capital Trust IV, NPB Capital Trust V and NPB Capital Trust VI (“Trusts”). On March 7, 2013, the Company redeemed all of the subordinated debentures issued by NPB Capital Trust II. The Company owns all of the common capital securities of the remaining Trusts. The Trusts issued preferred capital securities to investors and invested the proceeds in junior subordinated debentures issued by the Company. These debentures are the sole assets of the Trusts, which are considered variable interest entities. The Company is not the variable interest holder, and as such does not consolidate the Trusts. The liabilities to the Trusts are reflected as subordinated debentures on the Company’s consolidated balance sheet, and the common capital securities are included in other assets. Interest is paid on amounts borrowed from the Trusts and recorded in interest expense in the consolidated statement of income on the accrual basis of accounting.
	Costs related to the issuance of subordinated debentures are being amortized over the life of the instruments as an increase to interest expense in the consolidated statement of income using the interest method. The unamortized portion of the issuance costs is included within other assets on the consolidated balance sheet.
	The Company’s maximum exposure to the Trusts is $75 million, which is the Company’s liability to the Trusts and includes the Company’s investment in the Trusts.
	On January 1, 2007, the Company made an accounting policy election to record $65.2 million of debentures issued to NPB Capital Trust II on August 20, 2002 at fair value on the consolidated balance sheet. Prior to its redemption in the first quarter of 2013, changes in the estimated fair value for each reporting period were reported as net gains (losses) from fair value changes within non-interest income in the consolidated statement of income.
	Details of the Company’s obligations to the Trusts as of December 31, 2013 are as follows:
	Trusts		Principal	Issued	Maturity	Interest Rate
	NPB Capital Trust III		$20.6 Million	February 20, 2004	April 23, 2034	3 mo. LIBOR + 2.75% margin
	NPB Capital Trust IV		$20.6 Million	March 25, 2004	April 7, 2034	3 mo. LIBOR + 2.75% margin
	NPB Capital Trust V		$20.6 Million	April 7, 2004	April 7, 2034	3 mo. LIBOR + 2.75% margin
	NPB Capital Trust VI		$15.4 Million	January 19, 2006	March 15, 2036	3 mo. LIBOR + 1.38% margin
EMPLOYEE BENEFIT PLANS	'
	Employee Benefit Plans
	The Company accrues for benefits to employees and executive officers resulting from established plans and other contracts which are generally non-contributory. The benefits associated with these arrangements and plans are earned over a service period, and the Company estimates the amount of expense applicable to each plan or contract and includes it in salaries, wages and employee benefits expense in the consolidated statement of income for each period. The estimated obligations for the plans and contracts are reflected as liabilities on the consolidated balance sheet. The determination of each obligation and the related expense is based upon formulas in plan documents or agreements, but also requires judgment on the part of the Company to determine the assumptions applied to each formula. In addition, for the non-contributory pension plan there are amounts included in accumulated other comprehensive income (loss) related certain costs which require recognition over the course of several reporting periods.
INCOME TAXES	'
	Income Taxes
	The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recorded on the consolidated balance sheet for future tax events that arise from the difference between the financial statement and tax basis of assets and liabilities as measured by the enacted tax rates. Changes in tax rates are recognized in the Company’s financial statements during the period they are enacted. When a deferred tax asset or liability, or a change thereto, is recorded on the consolidated balance sheet, deferred tax expense or benefit is recorded within the income tax expense line of the consolidated statement of income for purposes of determining the current period’s net income.
	Deferred tax assets are recorded on the consolidated balance sheet at net realizable value. The Company periodically performs an assessment to evaluate the amount of deferred tax assets it is more likely than not to realize. Realization of deferred tax assets is dependent upon the amount of taxable income expected in future periods, as tax benefits require taxable income to be realized. If a valuation allowance is required, the deferred tax asset on the consolidated balance sheet is reduced via a corresponding income tax expense in the consolidated statement of income.
	The Company recognizes the benefit of a tax position in the financial statements only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. For these analyses, the Company may engage attorneys to provide opinions related to certain positions. Any interest and penalties, when applicable, related to uncertain tax positions is recognized in income tax expense in the consolidated statement of income.
FINANCIAL INSTRUMENTS WITH OFF BALANCE SHEET RISK	'
	Financial Instruments with Off-Balance-Sheet Risk
	The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit, standby letters of credit, forward sale commitments, and interest rate swaps. Certain of those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized on the consolidated balance sheet. The contract or notional amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.
	The Company’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of these instruments. The Company uses the same credit policies in making commitments and contractual obligations as it does for on-balance-sheet instruments. For interest rate swaps, the contract or notional amounts do not represent exposure to credit loss, but rather the credit risk is consistent with the estimated fair value due from counterparties to these contracts. The Company controls the credit risk of its interest rate swap agreements through credit approvals, limits and monitoring procedures. The Company reflects its estimate of credit risk for these instruments (including unfunded commitments, letters of credit, and interest rate swaps) in other liabilities on the consolidated balance sheet with the offsetting expense recorded in other operating expenses in the consolidated statement of income.
	Financial instruments that are derivatives are reported at estimated fair value within other assets or other liabilities on the consolidated balance sheet. An instrument is generally considered a derivative if it is based on one or more underlyings, no (or a minimal) initial net investment is required, and the contract can be net settled. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship. For derivatives not designated or qualifying as hedges, the gain or loss is included in the determination of net income. For derivatives designated and qualifying as hedges, only the ineffective portion is included in the determination of net income, the effective portion is included in the determination of net income consistent with the hedged item.
	The Company enters into interest rate swaps (swaps) to facilitate customer transactions and meet their financing needs. These swaps are considered derivatives, but are not designated in hedging relationships. These instruments have interest rate and credit risk associated with them. To mitigate the interest rate risk, the Company enters into offsetting interest rate swaps with counterparties. The counterparty swaps are also considered derivatives and are also not designated in hedging relationships. Interest rate swaps are recorded within other assets or other liabilities on the consolidated balance sheet at their estimated fair value. Changes to the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the consolidated statement of income.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	The Company may enter into interest rate swap contracts in order to hedge its exposure to the variability of cash flows on certain floating-rate obligations. Cash flow hedges are intended to convert liabilities from a floating-rate instrument to a fixed-rate instrument. The Company’s intention is to design cash flow hedges to qualify for hedge accounting, and as such the estimated fair value of the hedge would be recorded either in other assets or other liabilities with an offset, after estimated taxes, recorded in accumulated other comprehensive income (loss). The ineffective portion of the hedging relationship would be recorded in other operating expenses in the consolidated statement of income. Amounts would be reclassified from accumulated other comprehensive income (loss) to interest expense in the consolidated statement of income during the period the hedged item affects earnings. Cash flows associated with the hedges are treated consistently with the cash flows of the hedged item during the period in which they occur.
	The Company periodically enters into interest rate lock commitments with its mortgage loan customers whose loans are intended for sale after the loan is closed. These commitments are derivatives and, as such, are reported on the consolidated balance sheet at their estimated fair value. The Company’s methodology for estimating the fair value of these derivatives is based upon the change in pricing of mortgage-backed securities with similar interest rates and duration. To hedge the fair value risk associated with changing interest rates on these commitments, the Company enters into forward commitments to sell the loans. These hedges are economic hedges and are not designated in hedging relationships. The forward sale commitments are also derivatives and are recorded on the consolidated balance sheet at their estimated fair value. The Company’s methodology for valuing these derivatives is based upon the fair value of the closed loans and the change in fair value of the interest rate lock commitments, as previously described. The net change in the estimated fair value of the derivatives for commitments to customers and forward loan sale commitments during each period is recorded in mortgage banking income in the consolidated statement of income.
	The Company estimates the fair value of letters of credit as the fees paid by the customer or charged for the arrangement. The fair value is recorded in other liabilities on the consolidated balance sheet, and subsequently, the income is recognized in other operating income within non-interest income in the consolidated statement of income over the contractual life of the instrument. If required to perform on a standby letter of credit, the Company records an amount due from the customer, which is recorded net of any unaccreted liability. Additional amounts estimated to be uncollectible, net of estimated proceeds from collateral, are charged-off against the appropriate allowance on the consolidated balance sheet.
	Interest rate swap derivatives with the same counterparty and subject to master netting arrangements are not offset on the consolidated balance sheet. For additional detail refer to Footnote 13 within this section.
ACCUMULATED OTHER COMPREHENSIVE (LOSS) INCOME	'
	Accumulated Other Comprehensive Income
	Accumulated other comprehensive income ("AOCI") includes items that are subject to periodic measurement on the consolidated balance sheet but are not included in the determination of net income for the period in the consolidated statement of income. As such, amounts recorded in AOCI are on an after-tax basis and consist primarily of unrealized gains or losses on investment securities available-for-sale and changes in pension obligations.
SHARE-BASED COMPENSATION	'
	Share-Based Compensation
	The Company has certain share-based employee and director compensation plans. The related share-based employee compensation is included in salaries, wages and employee benefits expense in the consolidated statement of income during the period in which it is earned. Share-based director compensation expense is included in other operating expense in the consolidated statement of income. The compensation cost for share-based compensation arrangements is determined based upon the estimated fair value of the award at the grant date and is recognized as an expense over the service period. Performance criteria for share-based awards are factored into the amount of expense recognized when applicable. The Company records tax benefits of share-based payments as a financing cash inflow and corresponding operating cash outflow in the consolidated statement of cash flows during the period in which they occur.
	Option awards are granted with an exercise price at least equal to the market price of the Company’s stock at the date of grant. Option awards vest at such times as are determined by the Compensation Committee of the Board of Directors at the time of grant, but not before one year from the date of grant or later than five years from the date of grant. The options have a maximum term of ten years for incentive stock options or ten years, one month for non-qualified stock options.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	The Company utilizes the Black-Scholes option valuation model to estimate the fair value of options granted.  The model is sensitive to changes in assumptions which can materially affect the fair value estimate:
	•	The risk-free interest rates used are from published U.S. Treasury zero-coupon rates for bonds approximating the expected term of the option as of the option grant date;
	•	The expected dividend yield is computed based on the Company’s current dividend rate; and
	•	The Company relies exclusively on historical volatility as an input for determining the estimated fair value of stock options. The Company determines expected volatility based on the expected life of the option.
	In determining the expected life of the option grants, the Company observes the actual terms of prior grants with similar characteristics and the actual vesting schedule of the grants.
	Share-based payments are also granted in the form of restricted stock awards or units. Restricted stock is granted with service criteria and may also include performance criteria. The fair value of each award is estimated based on the fair value of the Company’s common stock on the date of grant.
	Share-based payment plans are further described in Footnote 17 within this section.
TREASURY STOCK	'
	Treasury Stock
	Shares of the Company’s common stock which are repurchased on the open market are classified as treasury stock on the consolidated balance sheet. Treasury stock is recorded at the cost at which it was obtained in the open market, and at the date of reissuance, treasury stock on the consolidated balance sheet is reduced by the cost for which it was purchased using specific identification, on a first-in, first-out basis.
EARNINGS PER SHARE	'
	Earnings Per Share
	Earnings per share is calculated on the basis of the weighted-average number of common shares outstanding during the year. All per share information in the financial statements is adjusted retroactively for the effect of stock dividends and splits.
	Diluted shares and earnings per share take into account the potential dilution that could occur if securities or other contracts to issue common stock were exercised and converted into common stock. The dilutive effect of stock options, warrants, and other instruments is calculated using the treasury stock method.
RECENT ACCOUNTING PRONOUNCEMENTS	'
	Recent Accounting Pronouncements
	Goodwill
	In September 2011, the Federal Accounting Standard Board ("FASB") simplified how entities test goodwill for impairment, whereby an entity has the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after its assessment, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it would not have to perform the current two-step goodwill impairment test. This amendment was effective for the Company for its fiscal year beginning January 1, 2012 and the adoption of this standard did not have a material effect on the financial condition or results of operations of the Company.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	Comprehensive Income
	In June 2011, the FASB released a standard requiring comprehensive income to be presented either in a single continuous statement or in two separate but consecutive statements. The single continuous statement format combines other comprehensive income, its components and total comprehensive income with the consolidated statement of income. In the two statement approach, the first statement would be the statement of income immediately followed by a separate statement which includes the components of other comprehensive income, total other comprehensive income and total comprehensive income. The standard was effective for the Company beginning January 1, 2012 and requires retrospective application. The Company early adopted the two statement approach for the year ended December 31, 2011 by including a consolidated statement of comprehensive income after the consolidated statement of income in this Report.
	In February 2013, the FASB released guidance on disclosures about reclassifications out of accumulated other comprehensive income. The issuance of this guidance now requires entities to disclose:
	•	For items reclassified out of accumulated other comprehensive income ("AOCI") and into net income in their entirety, the effect of the reclassification on each affected net income line item; and
	•	For AOCI reclassification items not reclassified in their entirety into net income, a cross reference to the related footnote where additional information on the effect of the reclassification is disclosed.
	The adoption of this disclosure requirement did not materially impact the Company's financial condition or result of operations.
	Balance Sheet Offsetting
	In January 2013, the FASB updated the disclosure requirements surrounding the offsetting of assets and liabilities on an entity's balance sheet. As part of the updated requirements, an entity shall disclose information to enable users of its financial statements to evaluate the effect or potential effect of rights of setoff associated with recognized derivatives, repurchase agreements, reverse repurchase agreements, and securities lending or securities borrowing transactions that are either (1) offset in the balance sheet or (2) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset on the balance sheet. The Company adopted this guidance for the year ended December 31, 2013. Adoption of this guidance did not materially impact the Company's financial condition or results of operations, however did result in additional disclosures.
	Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists
	In July 2013, the FASB issued explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The guidance requires, with limited exception, that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a DTA for a net operating loss carryforward, or similar tax loss, or a tax credit carryforward. The new guidance is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption and retrospective application are permitted. As this guidance only impacts financial statement presentation and related footnote disclosures, it will have no effect on the Company's financial position or results of operations.
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued
	Troubled Debt Restructurings by Creditors
	In January 2014, the FASB issued guidance to clarify when banks should reclassify mortgage loans collateralized by residential real estate properties from the loan portfolio to other real estate owned. The FASB defined an in-substance repossession or foreclosure to have occurred and a creditor is considered to have taken physical possession of residential real estate collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. The effective date is for annual periods, and interim periods within those annual periods, beginning after December 15, 2014, with early adoption permitted. The Company does not expect adoption of this guidance to have a material effect on the financial condition or results of operations of the Company.

Subordinated Debentures	'
	Subordinated Debentures
	At the beginning of 2013, the Company had five established statutory business Trusts: NPB Capital Trust II, NPB Capital Trust III, NPB Capital Trust IV, NPB Capital Trust V and NPB Capital Trust VI (“Trusts”). On March 7, 2013, the Company redeemed all of the subordinated debentures issued by NPB Capital Trust II. The Company owns all of the common capital securities of the remaining Trusts. The Trusts issued preferred capital securities to investors and invested the proceeds in junior subordinated debentures issued by the Company. These debentures are the sole assets of the Trusts, which are considered variable interest entities. The Company is not the variable interest holder, and as such does not consolidate the Trusts. The liabilities to the Trusts are reflected as subordinated debentures on the Company’s consolidated balance sheet, and the common capital securities are included in other assets. Interest is paid on amounts borrowed from the Trusts and recorded in interest expense in the consolidated statement of income on the accrual basis of accounting.
	Costs related to the issuance of subordinated debentures are being amortized over the life of the instruments as an increase to interest expense in the consolidated statement of income using the interest method. The unamortized portion of the issuance costs is included within other assets on the consolidated balance sheet.
	The Company’s maximum exposure to the Trusts is $75 million, which is the Company’s liability to the Trusts and includes the Company’s investment in the Trusts.
	On January 1, 2007, the Company made an accounting policy election to record $65.2 million of debentures issued to NPB Capital Trust II on August 20, 2002 at fair value on the consolidated balance sheet. Prior to its redemption in the first quarter of 2013, changes in the estimated fair value for each reporting period were reported as net gains (losses) from fair value changes within non-interest income in the consolidated statement of income.
	Details of the Company’s obligations to the Trusts as of December 31, 2013 are as follows:
	Trusts		Principal		Issued		Maturity		Interest Rate
	NPB Capital Trust III		$20.6 Million		February 20, 2004		April 23, 2034		3 mo. LIBOR + 2.75% margin

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]	'
Summary of activity related to share-based plans	'
	The Company, through its Compensation Committee of the Board of Directors, offers equity compensation to employees and non-employee directors of National Penn, National Penn Bank and other National Penn subsidiaries in the form of share-based awards.  Stock options, restricted stock awards (“RSAs”), and restricted stock units (“RSUs”) vest over time, upon the satisfaction of established performance criteria, or both.
	The Company believes such awards better align the interests of its employees and non-employee directors with those of its shareholders. Option awards are granted with an exercise price at least equal to the market price of the Company’s stock at the date of grant. Option and other share-based awards vest at such times as are determined by the Compensation Committee of the Board of Directors at the time of grant, but not before one year from the date of grant or later than five years from the date of grant.  The options have a maximum term of ten years for incentive stock options or ten years, one month for non-qualified stock options.
	The fair value of RSAs and RSUs is estimated based on the price of the Company’s common stock on the date of grant.  Compensation cost is measured ratably over the vesting period of the awards and reversed for awards which are forfeited due to unfulfilled service or performance criteria.
	Vesting of share-based awards is immediately accelerated in the event of a change-in-control; in the event the recipient’s service terminates due to death, disability or retirement (including a voluntary termination of employment at age 60 or more); or in the event of an involuntary termination of employment not for cause.
	Awards are currently granted under the Long-Term Incentive Compensation Plan, approved by shareholders in April 2005 (“2005 Plan”) and expiring November 30, 2014.  Under the terms of the 2005 Plan, a total of 5,304,500 shares of common stock have been made available for option, restricted stock, or other share-based awards. As of December 31, 2013, approximately 1.5 million shares remain available for issuance under the terms of the 2005 Plan.
	17. SHARE-BASED COMPENSATION - Continued
	Prior to the adoption of the 2005 Plan, the Company maintained other employee stock compensation plans ("Previous Company Plans"). A total of 5,048,577 shares of common stock were made available for option or restricted stock awards. At December 31, 2013, approximately 0.5 million shares remain outstanding from the Previous Company Plans. In addition to the Previous Company Plans, the Company issued 3,022,185 substitute stock options as a result of acquisitions made in 2008, of which, approximately 1.7 million options were outstanding at December 31, 2013.

	On January 30, 2014, under the terms of National Penn's previously announced repurchase plan, National Penn completed the repurchase of 7 million shares of its common stock from two affiliates of Warburg Pincus, at $10.77 per share (the closing price of National Penn common stock on the date the repurchase agreement was entered into). As a result, the ownership of National Penn common stock by these shareholders was reduced to approximately 13.6% of National Penn’s outstanding common stock. This transaction substantially completed our 2014 repurchase plan. For additional information, see National Penn’s Current Report on Form 8-K dated January 28, 2014.
