	Northwest Bancshares, Inc. (the “Company”) or (“NWBI”), a Maryland corporation headquartered in Warren, Pennsylvania, is a savings and loan holding company regulated by the Board of Governors of the Federal Reserve System. The Company was incorporated to be the successor to Northwest Bancorp, Inc. upon the completion of the mutual-to-stock conversion of Northwest Bancorp, MHC in December 2009. The primary activity of the Company is the ownership of all of the issued and outstanding common stock of Northwest Savings Bank, a Pennsylvania-chartered savings bank (“Northwest”). Northwest is regulated by the FDIC and the Pennsylvania Department of Banking. At September 30, 2013, Northwest operated 165 community-banking offices throughout Pennsylvania, western New York, eastern Ohio and Maryland.

	The accompanying unaudited consolidated financial statements include the accounts of the Company and its subsidiary, Northwest, and Northwest’s subsidiaries Northwest Settlement Agency, LLC, Northwest Consumer Discount Company, Northwest Financial Services, Inc., Northwest Advisors, Inc., Northwest Capital Group, Inc., Boetger & Associates, Inc., Allegheny Services, Inc., Great Northwest Corporation, Veracity Benefit Designs, Inc. and The Bert Company. The unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information or footnotes required for complete annual financial statements. In the opinion of management, all adjustments necessary for the fair presentation of the Company’s financial position and results of operations have been included. The consolidated statements have been prepared using the accounting policies described in the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 updated, as required, for any new pronouncements or changes. The following sections of our Summary of Significant Accounting Principals have been updated since the filing of our form 10K and are included herein.

	Investment Securities

	We classify marketable securities at the time of purchase as held-to-maturity, available-for-sale, or trading securities. Securities for which management has the intent and we have the ability to hold until their maturity are classified as held-to-maturity and are carried at cost, adjusted for amortization of premiums and accretion of discounts on a level yield basis (amortized cost). If it is management’s intent at the time of purchase to hold securities for an indefinite period of time and/or to use such securities as part of its asset/liability management strategy, the securities are classified as available-for-sale and are carried at fair value, with unrealized gains and losses reported as accumulated other comprehensive income/ (loss), a separate component of shareholders’ equity, net of tax. Securities classified as available-for-sale include securities that may be sold in response to changes in interest rates, resultant prepayment risk, or other market factors. Securities that are bought and held principally for the purpose of selling them in the near term are classified as trading and are reported at fair value, with changes in fair value included in earnings. The cost of securities sold is determined on a specific identification basis. We held no securities classified as trading at September 30, 2013 or December 31, 2012.

	On at least a quarterly basis, we review our investments that are in an unrealized loss position for other-than-temporary impairment (“OTTI”). An investment security is deemed impaired if the fair value of the investment is less than its amortized cost. If an investment security is determined to be impaired, we evaluate whether the decline in value is other-than-temporary. We also consider whether or not we expect to receive all of the contractual cash flows from the investment security based on factors that include, but are not limited to: the credit worthiness of the issuer and the historical and projected performance of the underlying collateral. Also, we may evaluate the business and financial outlook of the issuer, as well as broader economic performance indicators. We consider our intent to sell the investment securities and the likelihood that we will not have to sell the investment securities before recovery of their cost basis during our evaluation. Declines in fair value of investment securities that are deemed credit related are recognized in earnings while declines in fair value of investment securities deemed noncredit related are recorded in accumulated other comprehensive income, if we do not intend to sell and it is not likely we will be required to sell. If we intend to sell the security or if it’s more likely than not that we will be required to sell the security the entire unrealized loss is recorded in earnings.

	Federal law requires a member institution of the Federal Home Loan Bank (FHLB) system to hold stock of its district FHLB according to a predetermined formula. This stock is recorded at cost. Quarterly, we evaluate our investment in the FHLB of Pittsburgh for impairment. We evaluate recent and long-term operating performance, liquidity, funding and capital positions, stock repurchase history, dividend history and impact of legislative and regulatory changes. Based on our most recent evaluation, we have determined that no impairment write-downs are currently required.

	Loans Receivable

	Our loan portfolio segments consist of Personal Banking loans and Business Banking loans. Personal Banking loans include the following classes: residential mortgage loans, home equity loans and other consumer loans. Business Banking loans include the following classes: commercial real estate loans and commercial loans. All classes of loans are carried at their unpaid principal balance net of any deferred origination fees or costs and the allowance for estimated loan losses. Interest income on loans is credited to income as earned. Interest earned on loans for which no payments were received during the month is accrued at month end. Accrued interest on loans more than 90 days delinquent is reversed, and such loans are placed on nonaccrual.

	All classes of loans are placed on nonaccrual when principal or interest is 90 days or more delinquent, or when there is reasonable doubt that interest or principal will not be collected in accordance with the contractual terms. Interest receipts on all classes of nonaccrual and impaired loans are recognized as interest revenue when it has been determined that all principal and interest will be collected or are applied to principal when collectability of principal is in doubt. Nonaccrual loans generally are restored to an accrual basis when principal and interest become current and a period of performance has been established in accordance with the contractual terms, typically six months.

	A loan (from any class) is considered to be a trouble-debt restructured loan (TDR) when the restructuring constitutes a concession and the borrower is experiencing financial difficulties. TDRs may include certain modifications of terms of loans, receipts of assets from borrowers in partial or full satisfaction of loans, or a combination thereof. TDRs are impaired loans and are measured for impairment until the loan has performed in accordance with its modified terms for a reasonable period of time, generally six consecutive months. A modified loan is determined to be a TDR based on the contractual terms as specified by the original loan agreements of the most recent modification. Once classified a TDR, a loan is only removed from such classification under three circumstances: (1) the loan is paid off, (2) the loan is charged off, or (3) if, at the beginning of the current fiscal year, the loan has performed in accordance with the modified terms for a minimum of six consecutive months and at the time of modification the loan’s interest rate represented a then current market interest rate for a loan of similar risk.

	For all classes of loans, delinquency is measured based on the number of days since the payment due date. For all classes of loans, past due status is measured using the loan’s contractual maturity date.

	Loan fees and certain direct loan origination costs are deferred, and the net deferred fee or cost is then recognized using the level-yield method over the contractual life of the loan as an adjustment to interest income.

	The results of operations for the quarter ended and nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013, or any other period.

	Stock-Based Compensation

	On May 15, 2013, we awarded employees 511,100 stock options and directors 79,200 stock options with an exercise price of $12.44 and a grant date fair value of $1.03 per stock option. On May 15, 2013, we also awarded employees 240,700 restricted common shares and directors 29,700 restricted common shares with a grant date fair value of $12.55. Awarded stock options and common shares vest over a ten-year period with the first vesting occurring on the grant date. Stock-based compensation expense of $1.2 million and $1.1 million for the quarter ended September 30, 2013 and 2012, respectively, and $3.8 million and $3.5 million for the nine months ended September 30, 2013 and 2012, respectively, was recognized in compensation expense relating to our stock benefit plans. At September 30, 2013 there was compensation expense of $5.4 million to be recognized for awarded but unvested stock options and $15.8 million for unvested common shares.

	Income Taxes- Uncertain Tax Positions

	Accounting standards prescribe a comprehensive model for how a company should recognize, measure, present and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return. A tax benefit from an uncertain position may be recognized only if it is “more likely than not” that the position is sustainable, based on its technical merits. The tax benefit of a qualifying position is the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority having full knowledge of all relevant information. As of September 30, 2013 we had no liability for unrecognized tax benefits.

	We recognize interest accrued related to: (1) unrecognized tax benefits in federal and state income taxes and (2) refund claims in other operating income. We recognize penalties (if any) in federal and state income taxes. There is no amount accrued for the payment of interest or penalties at September 30, 2013. We are subject to audit by the Internal Revenue Service and any state in which we conduct business for the tax periods ended December 31, 2012, 2011 and 2010.

	We operate in two reportable business segments: Community Banking and Consumer Finance. The Community Banking segment provides services traditionally offered by full-service community banks, including business and personal deposit accounts and business and personal loans, as well as insurance, brokerage and investment management and trust services. The Consumer Finance segment, which is comprised of Northwest Consumer Discount Company, a subsidiary of Northwest, operates 50 offices in Pennsylvania and offers personal installment loans for a variety of consumer and real estate products. This activity is funded primarily through an intercompany borrowing relationship with Allegheny Services, Inc., a subsidiary of Northwest. Net income is the primary measure used by management to measure segment performance. The following tables provide financial information for these reportable segments. The “All Other” column represents the parent company and elimination entries necessary to reconcile to the consolidated amounts presented in the financial statements.

We review our investment portfolio on a quarterly basis for indications of impairment. This review includes analyzing the length of time and the extent to which amortized cost has exceeded fair values, the financial condition and near-term prospects of the issuer, including any specific events which may influence the operations of the issuer, and the intent to hold the investments for a period of time sufficient to allow for a recovery in value. Certain investments are evaluated using our best estimate of future cash flows. If the estimate of cash flows indicates that an adverse change has occurred, other-than-temporary impairment would be recognized for the amount of the unrealized loss that was deemed credit related.

Corporate issues

At September 30, 2013, we had five investments with a total amortized cost of $6.3 million and total fair value of $4.5 million, where the amortized cost exceeded the carrying value for more than 12 months. These investments were three single issuer trust preferred investments and two pooled trust preferred investments. The single issuer trust preferred investments were evaluated for other-than-temporary impairment by determining the strength of the underlying issuer. In all cases, the underlying issuer was “well-capitalized” for regulatory purposes. None of the issuers have deferred interest payments or announced the intention to defer interest payments. We believe the decline in fair value is related to the spread over three month LIBOR, on which the quarterly interest payments are based, as the spread over LIBOR is significantly lower than current market spreads on similar investments. We concluded the impairment of these three investments was considered noncredit related. In making that determination, we also considered the duration and the severity of the losses and whether we intend to hold these securities until the value is recovered, the securities are redeemed or maturity. The pooled trust preferred investments were evaluated for other-than-temporary impairment by considering the duration and severity of the losses, actual cash flows, projected cash flows, performing collateral, the class of investment owned and the amount of additional defaults the structure could withstand prior to the investment experiencing a disruption in cash flows. Neither of the investments experienced a cash flow disruption or are projecting a cash flow disruption. We concluded, based on all facts evaluated, the impairment of these two investments was noncredit related. Management asserts that we do not have the intent to sell these investments and that it is more likely than not, we will not have to sell the investments before recovery of their cost basis.

Mortgage-backed securities

Mortgage-backed securities include agency (FNMA, FHLMC, GNMA and SBA) mortgage-backed securities and non-agency collateralized mortgage obligations (“CMOs”). We review our portfolio of mortgage-backed securities quarterly for impairment. As of September 30, 2013, we believe the impairment within our portfolio of agency mortgage-backed securities is noncredit related. As of September 30, 2013, we had seven non-agency CMOs with a total amortized cost of $4.8 million and a total fair value of $5.0 million. None of these seven securities have had an amortized cost which has exceeded the fair value for more than 12 months and one security that has had an amortized cost which exceeded the fair value for less than 12 months. During the quarter and nine months ended September 30, 2013, we did not recognize other-than-temporary credit related impairment on this security. We determined the impairment was noncredit related by analyzing cash flow estimates, estimated prepayment speeds, loss severity and conditional default rates. We considered the discounted cash flow analysis as our primary evidence when we determined that the impairment on this security was noncredit related.

The following table shows issuer specific information, amortized cost, fair value, unrealized gain or loss and other-than-temporary impairment recorded in earnings for the portfolio of non-agency CMOs at September 30, 2013 (in thousands):

Municipal Securities

We review our portfolio of municipal securities quarterly for impairment. We initially evaluate municipal securities for other-than-temporary impairment by comparing the fair value, provided to us by a third party pricing source using quoted prices for similar assets that are actively traded, to the carrying value. When an investment’s fair value is below 80% of the amortized cost we then assess the stated interest rate and compare the stated interest rate to current market interest rates to determine if the decline in fair value is considered to be attributable to interest rates. If the stated interest rate approximates current interest rates for similar securities, we determine if the investment is rated and if so, if the rating has changed in the current period. If the rating has not changed during the current period, we review publicly available information to determine if there has been any negative change in the underlying municipality. As of September 30, 2013, none of the investments in our municipal securities portfolio had an amortized cost that exceeded the fair value for more than twelve months.

Credit related other-than-temporary impairment on all debt securities is recognized in earnings while noncredit related other-than-temporary impairment on available-for-sale debt securities, not expected to be sold, is recognized in other comprehensive income.

Our loan portfolios include loans that have been modified in a troubled debt restructuring (TDR), where concessions have been granted to borrowers who have experienced financial difficulties. These concessions typically result from our loss mitigation activities and could include: extending the note’s maturity date, permitting interest only payments, reducing the interest rate to a rate lower than current market rates for new debt with similar risk, reducing the principal payment, principal forbearance or other actions. These concessions are applicable to all loan segments and classes. Certain TDRs are classified as nonperforming at the time of restructuring and may be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period of at least six months.

When we modify loans in a TDR, we evaluate any possible impairment similar to other impaired loans based on the present value of expected future cash flows, discounted at the contractual interest rate of the original loan agreement, the loan’s observable market price or the current fair value of the collateral, less selling costs, for collateral dependent loans. If we determine that the value of the modified loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized through an allowance estimate or a charge-off to the allowance. In periods subsequent to modification, we evaluate all TDRs, including those that have payment defaults, for possible impairment, using ASC 310-10. As a result, loans modified in a TDR may have the financial effect of increasing the specific allowance associated with the loan.

Loans modified in a TDR are closely monitored for delinquency as an early indicator of possible future default. If loans modified in a TDR subsequently default, we evaluate the loan for possible further impairment. The allowance may be increased, adjustments may be made in the allocation of the allowance, partial charge-offs may be taken to further write-down the carrying value of the loan, or the loan may be charged-off completely.

During the nine months ended September 30, 2013, four home equity loan TDRs with a combined balance of $99,000, four residential mortgage loan TDRs with a combined balance of $357,000, four commercial real estate loan TDRs with a combined balance of $1.1 million and five commercial loan TDRs with a combined balance of $250,000 were charged off. Additionally, three home equity loan TDRs with a combined balance of $9,000, one residential mortgage loan TDR with a balance of $109,000, seven commercial real estate loan TDRs with a combined balance of $3.1 million and 22 commercial loan TDRs with a combined balance of $3.5 million were paid off. For TDRs that subsequently defaulted during the nine months ended September 30, 2013, one residential mortgage loan TDR with a balance of $79,000 was charged off and two commercial loan TDRs with a combined balance of $1.9 million were paid off and are included above. Additionally, one commercial loan TDR with a balance of $2.1 million was transferred to real estate owned.

Credit quality indicators: We categorize loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. We analyze loans individually by classifying the loans by credit risk. Credit relationships greater than or equal to $1.0 million classified as special mention or substandard are reviewed quarterly for deterioration or improvement to determine if the loan is appropriately classified. We use the following definitions for risk ratings other than pass:

Special mention — Loans designated as special mention have specific, well-defined risk issues, which create a high level of uncertainty regarding the long-term viability of the business. Loans in this class are considered to have high-risk characteristics. A special mention loan exhibits material negative financial trends due to company-specific or systemic conditions. If these potential weaknesses are not mitigated, they threaten the borrower’s capacity to meet its debt obligations. Special mention loans still demonstrate sufficient financial flexibility to react to and positively address the root cause of the adverse financial trends without significant deviations from their current business strategy. Their potential weaknesses deserve our close attention and warrant enhanced monitoring.

Substandard — Loans classified as substandard are inadequately protected by the current net worth and payment capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected.

Doubtful — Loans classified as doubtful have all the weaknesses inherent in those classified as substandard. In addition, those weaknesses make collection or liquidation in full highly questionable and improbable. A loan classified as doubtful exhibits discernible loss potential, but a complete loss seems very unlikely. The possibility of a loss on a doubtful loan is high, but because of certain important and reasonably specific pending factors that may strengthen the loan, its classification as an estimated loss is deferred until a more exact status can be determined.

Loss— Loans classified as loss are considered uncollectible and of such value that the continuance as a loan is not warranted. A loss classification does not mean that the loan has no recovery or salvage value; instead, it means that it is not practical or desirable to defer writing off all or a portion of a basically worthless loan even though partial recovery may be affected in the future.

	We issue standby letters of credit in the normal course of business. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party. We are required to perform under a standby letter of credit when drawn upon by the guaranteed third party in the case of nonperformance by our customer. The credit risk associated with standby letters of credit is essentially the same as that involved in extending loans to customers and is subject to normal loan underwriting procedures. Collateral may be obtained based on management’s credit assessment of the customer. At September 30, 2013, the maximum potential amount of future payments we could be required to make under these standby letters of credit was $28.8 million, of which $28.1 million is fully collateralized. At September 30, 2013, we had a liability, which represents deferred income, of $872,000 related to the standby letters of credit.

	(7) Earnings Per Share

	Basic earnings per common share (EPS) is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period, without considering any dilutive items. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company. All stock options outstanding during the quarter and nine months ended September 30, 2013 were included in the computation of diluted earnings per share because the stock options’ exercise price was less than the average market price of the common shares of $13.77 and $12.92, respectively. Stock options to purchase 3,119,002 shares of common stock with a weighted average exercise price of $12.28 per share were outstanding during the quarter and nine months ended September 30, 2012 but were not included in the computation of diluted earnings per share for these periods because the options’ exercise price was greater than the average market price of the common shares of $11.98 and $12.17, respectively.

	The computation of basic and diluted earnings per share follows (in thousands, except share data and per share amounts):

	The defined benefit pension plan was amended to lock-in all benefits earned through March 31, 2013 based on the plan formula using years of service and average monthly compensation as of March 31, 2013. The amendments also provide that, for service commencing January 1, 2013, additional benefits will be earned equal to 1% of career average pay for each year that a participant completes at least 1,000 hours of service. Also, effective April 1, 2013, participants who are eligible to receive required minimum distributions due to attaining age 70 ½ will be required to begin payment of benefits even though they may remain employed by us.

	(9) Disclosures About Fair Value of Financial Instruments

	Fair value information about financial instruments, whether or not recognized in the consolidated statement of financial condition, is required to be disclosed. These requirements exclude certain financial instruments and all nonfinancial instruments. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company.

	Financial assets and liabilities recognized or disclosed at fair value on a recurring basis and certain financial assets and liabilities on a non-recurring basis are accounted for using a three-level hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. This hierarchy gives the highest priority to quoted prices with readily available independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market inputs (Level 3). When various inputs for measurement fall within different levels of the fair value hierarchy, the lowest level input that has a significant impact on fair value measurement is used.

	Financial assets and liabilities are categorized based upon the following characteristics or inputs to the valuation techniques:

	· Level 1 — Financial assets and liabilities for which inputs are observable and are obtained from reliable quoted prices for identical assets or liabilities in actively traded markets. This is the most reliable fair value measurement and includes, for example, active exchange-traded equity securities.

	· Level 2 — Financial assets and liabilities for which values are based on quoted prices in markets that are not active or for which values are based on similar assets or liabilities that are actively traded. Level 2 also includes pricing models in which the inputs are corroborated by market data, for example, matrix pricing.

	· Level 3 — Financial assets and liabilities for which values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Level 3 inputs include the following:

	· Quotes from brokers or other external sources that are not considered binding;

	· Quotes from brokers or other external sources where it cannot be determined that market participants would in fact transact for the asset or liability at the quoted price;

	· Quotes and other information from brokers or other external sources where the inputs are not deemed observable.

	We are responsible for the valuation process and as part of this process may use data from outside sources in establishing fair value. We perform due diligence to understand the inputs used or how the data was calculated or derived. We also corroborate the reasonableness of external inputs in the valuation process.

	The carrying amounts reported in the consolidated statement of financial condition approximate fair value for the following financial instruments: cash on hand, interest-earning deposits in other institutions, federal funds sold and other short-term investments, accrued interest receivable, accrued interest payable, and marketable securities available-for-sale.

	Marketable Securities

	Where available, market values are based on quoted market prices, dealer quotes, and prices obtained from independent pricing services.

	Debt securities — available for sale - Generally, debt securities are valued using pricing for similar securities, recently executed transactions and other pricing models utilizing observable inputs. The valuation for most debt securities is classified as Level 2. Securities within Level 2 include corporate bonds, municipal bonds, mortgage-backed securities and US government obligations. Certain corporate debt securities do not have an active market and as such the broker pricing received uses alternative methods. The fair value of these corporate debt securities is determined by using a discounted cash flow model using market assumptions, which generally include cash flow, collateral and other market assumptions. As such, these securities are included herein as Level 3 assets.

	Equity securities — available for sale - Level 1 securities include publicly traded securities valued using quoted market prices. We consider the financial condition of the issuer to determine if the securities have indicators of impairment.

	Debt securities — held to maturity- The fair value of debt securities held to maturity is determined in the same manner as debt securities available for sale.

	Loans Receivable

	Loans with comparable characteristics including collateral and re-pricing structures are segregated for valuation purposes. Each loan pool is separately valued utilizing a discounted cash flow analysis. Projected monthly cash flows are discounted to present value using a market rate for comparable loans, which is not considered an exit price. Characteristics of comparable loans included remaining term, coupon interest, and estimated prepayment speeds. Delinquent loans are separately evaluated given the impact delinquency has on the projected future cash flow of the loan and the approximate discount or market rate.

	FHLB Stock

	Due to the restrictions placed on the transferability of FHLB stock it is not practical to determine the fair value.

	Deposit Liabilities

	The estimated fair value of deposits with no stated maturity, which includes demand deposits, money market, and other savings accounts, is the amount payable on demand. Although market premiums paid for depository institutions reflect an additional value for these low-cost deposits, adjusting fair value for any value expected to be derived from retaining those deposits for a future period of time or from the benefit that results from the ability to fund interest-earning assets with these deposit liabilities is prohibited. The fair value estimates of deposit liabilities do not include the benefit that results from the low-cost funding provided by these deposits compared to the cost of borrowing funds in the market. Fair values for time deposits are estimated using a discounted cash flow calculation that applies contractual cost currently being offered in the existing portfolio to current market rates being offered locally for deposits of similar remaining maturities. The valuation adjustment for the portfolio consists of the present value of the difference of these two cash flows, discounted at the assumed market rate of the corresponding maturity.

	Borrowed Funds

	Fixed rate advances are valued by comparing their contractual cost to the prevailing market cost. The carrying amount of repurchase agreements approximates the fair value.

	Junior Subordinated Debentures

	The fair value of junior subordinated debentures is calculated using the discounted cash flows at the prevailing rate of interest.

	Cash flow hedges — Interest rate swap agreements (“swaps”)

	The fair value of the swaps is the amount we would expect to pay to terminate the agreements and is based upon the present value of the expected future cash flows using the LIBOR swap curve, the basis for the underlying interest rate.

	Off-Balance Sheet Financial Instruments

	These financial instruments generally are not sold or traded, and estimated fair values are not readily available. However, the fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements. Commitments to extend credit are generally short-term in nature and, if drawn upon, are issued under current market terms. At September 30, 2013 and December 31, 2012, there was no significant unrealized appreciation or depreciation on these financial instruments.

Impaired loans — A loan is considered to be impaired as described in the Overview of Critical Accounting Policies Involving Estimates, Allowance for Loan Losses section. We classify loans individually evaluated for impairment that require a specific or TDR reserve as nonrecurring Level 3.

Real Estate Owned — Real estate owned is comprised of property acquired through foreclosure or voluntarily conveyed by delinquent borrowers. These assets are recorded on the date acquired at the lower of the related loan balance or fair value, less estimated disposition costs, with the fair value being determined by appraisal. Subsequently, foreclosed assets are valued at the lower of the amount recorded at acquisition date or fair value, less estimated disposition costs. We classify all real estate owned as nonrecurring Level 3.

The table presents additional quantitative information about assets measured at fair value on a recurring and nonrecurring basis and for which we have utilized Level 3 inputs to determine fair value at September 30, 2013 (dollar amounts in thousands):

		Fair value		Valuation		Significant	Range (weighted
		Fair value		techniques		unobservable inputs	average)

Debt securities		$	11,708	Discounted cash		Discount margin	0.35% to 2.1% (0.69)%
				flow		Default rates	1.00%
						Prepayment speeds	1.00% annually

Loans measured for impairment		76,205		Appraisal		Estimated cost to sell	10%
				value (1)

Real estate owned		20,173		Appraisal		Estimated cost to sell	10%
				value (1)



(1) Fair value is generally determined through independent appraisals of the underlying collateral, which may include level 3 inputs that are not identifiable, or by using the discounted cash flow method if the loan is not collateral dependent.

The significant unobservable inputs used in the fair value measurement of our debt securities are discount margins, default rates and prepayment speeds. Significant increases in any of those rates would result in a significantly lower fair value measurement.

	(10) Mortgage Loan Servicing

	Mortgage servicing assets are recognized as separate assets when, through loan originations and purchases, the underlying loan is subsequently sold. Upon sale, the mortgage servicing right (“MSR”) is established, which represents the then-fair value of future net cash flows expected to be realized for performing the servicing activities. The fair value of the MSRs are estimated by calculating the present value of estimated future net servicing cash flows, taking into consideration actual and expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors, which are determined based on current market conditions. In determining the fair value of the MSRs, stochastic modeling is performed using variables such as the forward yield curve, prepayment rates, annual service cost, average life expectancy and option adjusted spreads. MSRs are amortized against mortgage banking income in proportion to, and over the period of, the estimated future net servicing income of the underlying mortgage loans. MSRs are recorded in other assets on the consolidated statements of financial condition.

	Capitalized MSRs are evaluated quarterly for impairment based on the estimated fair value of those rights. The MSRs are stratified by certain risk characteristics, primarily loan term and note rate. If impairment exists within a risk stratification tranche, a valuation allowance is established through a charge to income equal to the amount by which the carrying value exceeds the fair value. If it is later determined all or a portion of the temporary impairment no longer exists for a particular tranche, the valuation allowance is reduced or eliminated. We do not directly hedge against realized or potential future impairment losses on our MSRs.

	We have two statutory business trusts: Northwest Bancorp Capital Trust III, a Delaware statutory business trust and Northwest Bancorp Statutory Trust IV, a Connecticut statutory business trust (“Trusts”). These trusts exist solely to issue preferred securities to third parties for cash, issue common securities to the Company in exchange for capitalization of the Trusts, invest the proceeds from the sale of the trust securities in an equivalent amount of debentures of the Company, and engage in other activities that are incidental to those previously listed.

	Northwest Bancorp Capital Trust III (Trust III) issued 50,000 cumulative trust preferred securities in a private transaction to a pooled investment vehicle on December 5, 2006 (liquidation value of $1,000 per preferred security or $50,000,000) with a stated maturity of December 30, 2035. These securities carry a floating interest rate, which is reset quarterly, equal to three-month LIBOR plus 1.38%. Northwest Bancorp Statutory Trust IV (Trust IV) issued 50,000 cumulative trust preferred securities in a private transaction to a pooled investment vehicle on December 15, 2006 (liquidation value of $1,000 per preferred security or $50,000,000) with a stated maturity of December 15, 2035. These securities carry a floating interest rate, which is reset quarterly, equal to three-month LIBOR plus 1.38%. The Trusts have invested the proceeds of the offerings in junior subordinated deferrable interest debentures issued by the Company. The structure of these debentures mirrors the structure of the trust-preferred securities. Trust III holds $51,547,000 of the Company’s junior subordinated debentures and Trust IV holds $51,547,000 of the Company’s junior subordinated debentures. These subordinated debentures are the sole assets of the Trusts. Cash distri-butions on the trust securities are made on a quarterly basis to the extent interest on the debentures is received by the Trusts. We have the right to defer payment of interest on the subordinated debentures at any time, or from time-to-time, for periods not exceeding five years. If interest payments on the subordinated debentures are deferred, the distributions on the trust preferred securities are also deferred. Interest on the subordinated debentures and distributions on the trust securities is cumulative. To date, there have been no interest deferrals. Our obligation constitutes a full, irrevocable, and unconditional guarantee on a subordinated basis of the obligations of the trust under the preferred securities.

	We entered into four interest rate swap agreements (swaps), designating the swaps as cash flow hedges. The swaps are intended to protect against the variability of cash flows associated with Trust III and Trust IV. The first two swaps modify the re-pricing characteristics of Trust III, wherein (i) for a five year period, which expired on September 30, 2013, the Company received interest of three-month LIBOR from a counterparty and paid a fixed rate of 4.20% to the same counterparty calculated on a notional amount of $25.0 million and (ii) for a ten year period expiring in September 2018, the Company receives interest of three-month LIBOR from a counterparty and pays a fixed rate of 4.61% to the same counterparty calculated on a notional amount of $25.0 million. The second two swaps modify the re-pricing characteristics of Trust IV, wherein (i) for a seven year period expiring in September 2015, the Company receives interest of three-month LIBOR from a counterparty and pays a fixed rate of 3.85% to the same counterparty calculated on a notional amount of $25.0 million and (ii) for a ten year period in expiring September 2018,the Company receives interest of three-month LIBOR from a counterparty and pays a fixed rate of 4.09% to the same counterparty calculated on a notional amount of $25.0 million. The swap agreements were entered into with a counterparty that met our credit standards and the agreements contain collateral provisions protecting the at-risk party. We believe that the credit risk inherent in the contracts is not significant. At September 30, 2013, $9.5 million of cash was pledged as collateral to the counterparty.

	At September 30, 2013, the fair value of the swap agreements was $(8.9) million and was the amount we would have expected to pay if the contracts were terminated. There was no material hedge ineffectiveness for these swaps.

	We establish accruals for legal proceedings when information related to the loss contingencies represented by those matters indicates both that a loss is probable and that the amount of loss can be reasonably estimated. As of September 30, 2013 we have accrued $2.2 million. This amount is based on our analysis of currently available information and is subject to significant judgment and a variety of assumptions and uncertainties. Any such accruals are adjusted thereafter as appropriate to reflect changes in circumstances. Due to the inherent subjectivity of assessments and unpredictability of outcomes of legal proceedings, any amounts accrued may not represent the ultimate loss to us from legal proceedings.

	Toth v. Northwest Savings Bank

	On May 7, 2012, we were named as a defendant in an alleged class action lawsuit filed in the Court of Common Pleas of Allegheny County, Pennsylvania, captioned as Toth v. Northwest Savings Bank, No. GD-12-8014. The Complaint challenges the manner in which debit card transaction overdraft fees were charged and the policies related to the posting order of debit card transactions. The Complaint asserts various claims under state law and seeks compensatory damages and attorneys’ fees. We filed preliminary objections seeking dismissal of the case on June 29, 2012. In response, the plaintiff filed an Amended Complaint on September 6, 2012. On November 5, 2012, we filed preliminary objections to the Amended Complaint. Plaintiff filed her opposition to our preliminary objections on December 6, 2012, and we filed our reply in support of the preliminary objections on January 3, 2013. On June 25, 2013, the Court entered an Opinion and Order sustaining our preliminary objections to several counts of plaintiff’s First Amended Complaint, but overruling objections to plaintiff’s asserted violation of Pennsylvania’s Unfair Trade Practices and Consumer Protection Law (“UTPCPL”). We have filed an Answer and New Matter to plaintiff’s First Amended Complaint and seek to appeal the decision pertaining to plaintiff’s UTPCPL claim. We intend to vigorously defend against the plaintiff’s claims and to oppose any effort to certify a class in this case. At this stage of the lawsuit, it is not yet possible to estimate potential losses, if any. Although it is not possible to predict the ultimate resolution or financial liability with respect to this litigation, management after consultation with legal counsel, currently does not anticipate that the aggregate liability, if any, arising out of this proceeding will have a material adverse effect on our financial position, or cash flows; although, at the present time, we are not in a position to determine whether such proceeding will have a material adverse effect on our results of operations in any future quarterly reporting period.

	American Equity Rentals One, LLC v. Northwest Savings Bank

	On August 3, 2012, we were named as a defendant in a lawsuit filed in the Circuit Court for Baltimore County, Maryland, No. 03-C-12-00797807 by American Equity Rentals One, LLC, and others, obligors against whom we obtained confessed judgments, upon the borrowers’ default on several related credit facilities. The obligor-plaintiffs allege tort claims against us and one of our loan officers arising out of the lending relationship. On September 6, 2013, we entered into a global settlement with American Equity Rentals One, LLC and the other obligors wherein it was agreed that the obligors would dismiss, with prejudice, the aforementioned tort claims and repay certain monies owed under the confessed judgments. As a result of the settlement, the tort claims have been resolved without any material adverse effect on our financial position or cash flows.

	USDA v. Kathleen M. Schwab and Brian G. Schwab v. Northwest Savings Bank

	On December 19, 2012, the Schwabs filed a Complaint against us in the Court of Common Pleas of Clarion County, Pennsylvania, No. 409-2012 to join us as an additional defendant alleging that if it is determined that the United States Department of Agriculture (“USDA”) is entitled to relief (the mortgages are reformed and corrected by the Court so as to add Brian G. Schwab’s name to the mortgages), then we are solely liable to the USDA or we are jointly liable with the Schwabs, or liable over the Schwabs, with regard to the mortgages held by the USDA. On February 1, 2013, we filed Preliminary Objections to the Complaint joining us on the grounds that the USDA’s lawsuit does not involve any claim for money. We await a decision on our Preliminary Objections. At this stage of the lawsuit, it is not yet possible to estimate potential losses, if any. Although it is not possible to predict the ultimate resolution or financial liability with respect to this litigation, management, after consultation with legal counsel, currently does not anticipate that the aggregate liability, if any, arising out of this proceeding will have a material adverse effect on our financial position, or cash flows; although, at the present time, we are not in a position to determine whether such proceeding will have a material adverse effect on our results of operations in any future quarterly reporting period.

	Northwest Savings Bank v. Albert S. Marshal and Boca Rio Townhome Association, Inc.

	On July 8, 2011, we initiated a mortgage foreclosure lawsuit filed in the Court of Common Pleas, Dauphin County, Pennsylvania, captioned as Northwest Savings Bank v. Albert S. Marshal and Boca Rio Townhome Association, Inc. (“Boca Rio”), No. 2011 CV 6719 MF. The Complaint seeks to foreclose on two mortgages with respect to the real property located at 920 West Areba Avenue, Hershey, Dauphin County, Pennsylvania 17033 (the “Property”). Defendant Marshal was the mortgagor of the two mortgages, and Boca Rio is the party to whom the Property was transferred without the mortgages having been paid in full. In response, on August 8, 2011, Defendant Boca Rio filed its Answer with New Matter and Counterclaim. In the Counterclaim, Defendant Boca Rio alleges that we violated the Mortgage Satisfaction Act, 21 P.S. §721-1 et. seq., because we did not satisfy the mortgages that Defendant Boca Rio alleges they paid in full. On August 29, 2011, we filed Preliminary Objections to Defendant Boca Rio’s Counterclaim, seeking dismissal of the Counterclaim because Defendant Boca Rio was not a mortgagor under the Mortgage Satisfaction Act and therefore, did not have standing to bring a claim. On September 15, 2011, Defendant Boca Rio filed an Answer with New Matter and Amended Counterclaim. On September 30, 2011, we filed Preliminary Objections to Defendant Boca Rio’s Amended Counterclaim. On October 11, 2011, Defendant Boca Rio filed its Answer to our Preliminary Objections. The Court denied our Preliminary Objections on March 6, 2012. We recently filed a Motion for Partial Summary Judgment seeking dismissal of the Counterclaim. We intend to continue to vigorously defend against Defendant Boca Rio’s claims asserted in the Counterclaim as well as continue to prosecute the mortgage foreclosure action. At this stage of the lawsuit, it is not yet possible to estimate potential losses, if any. Although it is not possible to predict the ultimate resolution or financial liability with respect to this litigation, management, after consultation with legal counsel, currently does not anticipate that the aggregate liability, if any, arising out of this proceeding will have a material adverse effect on our financial position, or cash flows; although, at the present time, we are not in a position to determine whether such proceeding will have a material adverse effect on our results of operations in any future quarterly reporting period.

Investment Securities	'
	Investment Securities

	We classify marketable securities at the time of purchase as held-to-maturity, available-for-sale, or trading securities. Securities for which management has the intent and we have the ability to hold until their maturity are classified as held-to-maturity and are carried at cost, adjusted for amortization of premiums and accretion of discounts on a level yield basis (amortized cost). If it is management’s intent at the time of purchase to hold securities for an indefinite period of time and/or to use such securities as part of its asset/liability management strategy, the securities are classified as available-for-sale and are carried at fair value, with unrealized gains and losses reported as accumulated other comprehensive income/ (loss), a separate component of shareholders’ equity, net of tax. Securities classified as available-for-sale include securities that may be sold in response to changes in interest rates, resultant prepayment risk, or other market factors. Securities that are bought and held principally for the purpose of selling them in the near term are classified as trading and are reported at fair value, with changes in fair value included in earnings. The cost of securities sold is determined on a specific identification basis. We held no securities classified as trading at September 30, 2013 or December 31, 2012.

	On at least a quarterly basis, we review our investments that are in an unrealized loss position for other-than-temporary impairment (“OTTI”). An investment security is deemed impaired if the fair value of the investment is less than its amortized cost. If an investment security is determined to be impaired, we evaluate whether the decline in value is other-than-temporary. We also consider whether or not we expect to receive all of the contractual cash flows from the investment security based on factors that include, but are not limited to: the credit worthiness of the issuer and the historical and projected performance of the underlying collateral. Also, we may evaluate the business and financial outlook of the issuer, as well as broader economic performance indicators. We consider our intent to sell the investment securities and the likelihood that we will not have to sell the investment securities before recovery of their cost basis during our evaluation. Declines in fair value of investment securities that are deemed credit related are recognized in earnings while declines in fair value of investment securities deemed noncredit related are recorded in accumulated other comprehensive income, if we do not intend to sell and it is not likely we will be required to sell. If we intend to sell the security or if it’s more likely than not that we will be required to sell the security the entire unrealized loss is recorded in earnings.

	Federal law requires a member institution of the Federal Home Loan Bank (FHLB) system to hold stock of its district FHLB according to a predetermined formula. This stock is recorded at cost. Quarterly, we evaluate our investment in the FHLB of Pittsburgh for impairment. We evaluate recent and long-term operating performance, liquidity, funding and capital positions, stock repurchase history, dividend history and impact of legislative and regulatory changes. Based on our most recent evaluation, we have determined that no impairment write-downs are currently required.

Loans Receivable	'
	Loans Receivable

	Our loan portfolio segments consist of Personal Banking loans and Business Banking loans. Personal Banking loans include the following classes: residential mortgage loans, home equity loans and other consumer loans. Business Banking loans include the following classes: commercial real estate loans and commercial loans. All classes of loans are carried at their unpaid principal balance net of any deferred origination fees or costs and the allowance for estimated loan losses. Interest income on loans is credited to income as earned. Interest earned on loans for which no payments were received during the month is accrued at month end. Accrued interest on loans more than 90 days delinquent is reversed, and such loans are placed on nonaccrual.

	All classes of loans are placed on nonaccrual when principal or interest is 90 days or more delinquent, or when there is reasonable doubt that interest or principal will not be collected in accordance with the contractual terms. Interest receipts on all classes of nonaccrual and impaired loans are recognized as interest revenue when it has been determined that all principal and interest will be collected or are applied to principal when collectability of principal is in doubt. Nonaccrual loans generally are restored to an accrual basis when principal and interest become current and a period of performance has been established in accordance with the contractual terms, typically six months.

	A loan (from any class) is considered to be a trouble-debt restructured loan (TDR) when the restructuring constitutes a concession and the borrower is experiencing financial difficulties. TDRs may include certain modifications of terms of loans, receipts of assets from borrowers in partial or full satisfaction of loans, or a combination thereof. TDRs are impaired loans and are measured for impairment until the loan has performed in accordance with its modified terms for a reasonable period of time, generally six consecutive months. A modified loan is determined to be a TDR based on the contractual terms as specified by the original loan agreements of the most recent modification. Once classified a TDR, a loan is only removed from such classification under three circumstances: (1) the loan is paid off, (2) the loan is charged off, or (3) if, at the beginning of the current fiscal year, the loan has performed in accordance with the modified terms for a minimum of six consecutive months and at the time of modification the loan’s interest rate represented a then current market interest rate for a loan of similar risk.

	For all classes of loans, delinquency is measured based on the number of days since the payment due date. For all classes of loans, past due status is measured using the loan’s contractual maturity date.

	Loan fees and certain direct loan origination costs are deferred, and the net deferred fee or cost is then recognized using the level-yield method over the contractual life of the loan as an adjustment to interest income.

	The results of operations for the quarter ended and nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013, or any other period.

Stock-Based Compensation	'
	Stock-Based Compensation

	On May 15, 2013, we awarded employees 511,100 stock options and directors 79,200 stock options with an exercise price of $12.44 and a grant date fair value of $1.03 per stock option. On May 15, 2013, we also awarded employees 240,700 restricted common shares and directors 29,700 restricted common shares with a grant date fair value of $12.55. Awarded stock options and common shares vest over a ten-year period with the first vesting occurring on the grant date. Stock-based compensation expense of $1.2 million and $1.1 million for the quarter ended September 30, 2013 and 2012, respectively, and $3.8 million and $3.5 million for the nine months ended September 30, 2013 and 2012, respectively, was recognized in compensation expense relating to our stock benefit plans. At September 30, 2013 there was compensation expense of $5.4 million to be recognized for awarded but unvested stock options and $15.8 million for unvested common shares.

Income Taxes - Uncertain Tax Positions	'
	Income Taxes- Uncertain Tax Positions

	Accounting standards prescribe a comprehensive model for how a company should recognize, measure, present and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return. A tax benefit from an uncertain position may be recognized only if it is “more likely than not” that the position is sustainable, based on its technical merits. The tax benefit of a qualifying position is the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority having full knowledge of all relevant information. As of September 30, 2013 we had no liability for unrecognized tax benefits.

	We recognize interest accrued related to: (1) unrecognized tax benefits in federal and state income taxes and (2) refund claims in other operating income. We recognize penalties (if any) in federal and state income taxes. There is no amount accrued for the payment of interest or penalties at September 30, 2013. We are subject to audit by the Internal Revenue Service and any state in which we conduct business for the tax periods ended December 31, 2012, 2011 and 2010.
