Evaluation of Impairment of Securities
The Company did not record any other-than-temporary impairment ("OTTI") losses for the three and nine months ended September 30, 2013. During the year ended December 31, 2012, the Company recorded $0.2 million of OTTI on an equity security in the second quarter.
As of September 30, 2013 and December 31, 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 September 30, 2013, gross unrealized losses totaled $34.5 million, and the gross unrealized losses of securities in an unrealized loss position for twelve months or longer totaled $2.6 million, of which $2.0 million is attributable to state and municipal bonds and $0.4 million attributable to corporate securities and other.  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 $44.1 million and $68.4 million as of September 30, 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 $24.3 million, net, of its capital stock from the Company at par/cost. During 2012 and 2013 the Company received and recorded dividends on its FHLB stock.

	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 September 30, 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 the reasonably possible exposure.

	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 one another, there was no impact on other operating income for the three and nine months ended September 30, 2013. For additional analysis of the fair value on interest rate swaps, refer to Footnote 11 within this section. Cash collateral pledged for swaps in a liability position was $11.6 million at September 30, 2013. Cash collateral held for swaps in an asset position was $0.2 million at September 30, 2013.

Fair Value Disclosures [Abstract]	'
FAIR VALUE MEASUREMENTS AND FAIR VALUE OF FINANCIAL INSTRUMENTS	'
	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.
	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 performs benchmarking analysis to project security price movements and evaluates inconsistent trends, 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 nine months ended September 30, 2012, non-interest income included a gain of $0.9 million for the change in fair value. The fair value of the subordinated debenture was based on an unadjusted, quoted price of the traded asset (formerly Nasdaq: “NPBCO”) in an active market on the final day of each month.
	The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2013 and December 31, 2012, by level within the fair value hierarchy. Financial assets and liabilities 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 of loans held-for-sale is estimated based upon available market data for mortgage-backed securities with similar interest rates and maturities.  The Company did not record a lower of cost or estimated fair value adjustment on loans held-for-sale as of September 30, 2013 and December 31, 2012.
The recorded investment in impaired loans totaled $64.5 million with a specific reserve of $8.0 million at September 30, 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 September 30, 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.  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 estimation methodologies, resulting fair values and recorded carrying amounts are as follows:

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.
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 September 30, 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.

PENSION PLAN	'
	12.  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's 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. 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.
	The Company does not expect to make a contribution in 2013 because the plan’s funding credit balance will be applied toward reducing the contribution requirement. The Company’s expected long-term rate of return on plan assets is 7.25%.
	Net periodic benefit cost includes the following components:

Segment Reporting [Abstract]	'
SEGMENT REPORTING	'
	SEGMENT REPORTING
	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 summary of significant accounting policies in the Company’s most recent Annual Report on Form 10-K.
	Reportable segment-specific information and reconciliation to consolidated financial information is as follows:
