	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 March 31, 2014, 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., Northwest Retirement Services, Allegheny Services, Inc., Great Northwest Corporation, Northwest Insurance Services and Evans Capital Management, Inc. 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, 2013 updated, as required, for any new pronouncements or changes.

	The results of operations for the quarter ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014, or any other period.

	Stock-Based Compensation

	Stock-based compensation expense of $1.2 million and $1.1 million for the quarters ended March 31, 2014 and 2013, respectively, was recognized in compensation expense relating to our stock benefit plans. At March 31, 2014 there was compensation expense of $4.9 million to be recognized for awarded but unvested stock options and $14.6 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 March 31, 2014 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 March 31, 2014. 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.

	Recent Accounting Pronouncements

	In January 2014, the FASB issued ASU No. 2014-01, “Accounting for Investments in Qualified Affordable Housing Projects.” This guidance permits reporting entities to make an accounting policy election to account for investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. The proportional amortization method permits the amortization of the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the net investment performance in the income statement as a component of income tax expense. This guidance is effective retrospectively for fiscal years and interim periods within those years, beginning after December 15, 2014, and early adoption is permitted. We do not expect that this standard will have a material impact on our results of operations or financial position.

	In January 2014, the FASB issued ASU No. 2014-04, “Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure”. This guidance clarifies that an in substance repossession or foreclosure has occurred, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or 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. Interim and annual disclosure is required of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. This guidance is effective using either the modified retrospective transition method or a prospective transition method for fiscal years and interim periods within those years, beginning after December 15, 2014, and early adoption is permitted. We do not expect that this standard will have a material impact on our results of operations or financial position.

	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 costs have 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 is recognized for the amount of the unrealized loss that was deemed credit related.

The following table shows the fair value of and gross unrealized losses on investment securities, aggregated by investment category and length of time that the individual securities have been in a continuous unrealized loss position at March 31, 2014 (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 primarily 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 during 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 March 31, 2014, 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.

The table below shows a cumulative roll forward of credit losses recognized in earnings for debt securities held and not intended to be sold for the quarter ended (in thousands):

		2014			2013
Beginning balance at January 1, (1)		$	10,342		9,811

Reduction for losses realized during the quarter		(8		)	(67	)
Additional credit losses on debt securities for which other-than-temporary impairment was previously recognized		—			—
Ending balance at March 31,		$	10,334		9,744


(1) – The beginning balance represents credit losses included in other-than-temporary impairment charges recognized on debt securities in prior periods.

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.

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 possible in the future.

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 March 31, 2014, the maximum potential amount of future payments we could be required to make under these standby letters of credit was $26.3 million, of which $25.2 million is fully collateralized. At March 31, 2014, we had a liability, which represents deferred income, of $931,000 related to the standby letters of credit. There are no recourse provisions that would enable us to recover any amounts from third parties.

	(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 ended March 31, 2014 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 $14.47 during the quarter. Stock options to purchase 4,500 shares of common stock with a weighted average exercise price of $12.48 per share were outstanding during the quarter ended March 31, 2013 but were not included in the computation of diluted earnings per share for this period because the options’ exercise price was greater than the average market price of the common shares of $12.45 during the quarter.

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. Characteristics include 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. 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.

	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 March 31, 2014 and December 31, 2013, 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 March 31, 2014 (dollar amounts in thousands):

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

Debt securities		$	12,391	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		60,632		Appraisal		Estimated cost to sell		10%
				value (1)

Real estate owned		16,692		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) Guaranteed Preferred Beneficial Interests in the Company’s Junior Subordinated Deferrable Interest Debentures (Trust Preferred Securities) and Interest Rate Swaps

	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 are currently a counterparty to three 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 swap modifies the re-pricing characteristics of Trust III, wherein 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 other 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 expiring in 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 March 31, 2014, $8.4 million of cash was pledged as collateral to the counterparty.

	At March 31, 2014, the fair value of the swap agreements was $(7.7) 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 March 31, 2014 we have accrued $2.4 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, Ashley Toth (“Plaintiff”) filed a putative class action complaint in the Court of Common Pleas of Allegheny County, Pennsylvania against Northwest Savings Bank (“Northwest”). Plaintiff’s complaint alleged state law claims related to Northwest’s order of posting ATM and debit card transactions and the assessment of overdraft fees on deposit customer accounts. Northwest filed preliminary objections to the putative class action complaint on June 29, 2012. On September 6, 2012, Plaintiff filed an amended putative class action complaint containing substantially the same allegations as the initial putative class action complaint. On November 5, 2012, Northwest filed preliminary objections to the amended putative class action complaint. Plaintiff filed her opposition to Northwest’s preliminary objections on December 6, 2012, and Northwest filed its reply in support of the preliminary objections on January 3, 2013. On June 25, 2013, the court entered an order, granting in part and overruling in part, Northwest’s preliminary objections.

	On November 18, 2013, the parties participated in a mediation and reached an agreement in principle, subject to the preparation and execution of a mutually acceptable settlement agreement and release, to fully, finally and completely settle, resolve, discharge and release all claims that have been or could have been asserted in the action on a class-wide basis. The proposed settlement contemplates that, in return for a full and complete release of claims by Plaintiff and the settlement class members, Northwest will create a settlement fund for distribution to the settlement class members after certain court-approved reductions, including for attorney’s fees and expenses. The proposed settlement is subject to preliminary and final court approval.

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 March 31, 2014 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 March 31, 2014. 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.
