Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Informational Disclosures	Basis of Presentation and Informational Disclosures 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 primary activity of the Company is the ownership of all of the issued and outstanding common stock of Northwest Bank, a Pennsylvania-chartered savings bank (“Northwest”). Northwest is regulated by the FDIC and the Pennsylvania Department of Banking. Northwest operates 173 community-banking offices throughout Pennsylvania, western New York, and eastern Ohio. 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., Allegheny Services, Inc., Great Northwest Corporation, Boetger & Associates, 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, 2016 updated, as required, for any new pronouncements or changes. The results of operations for the quarter and six months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 , or any other period. Stock-Based Compensation On May 17, 2017, the Company awarded employees 754,210 stock options and directors 64,800 stock options with an exercise price of $15.57 and grant date fair value of $1.55 per stock option, and the Company awarded employees 353,750 restricted common shares and directors 24,300 restricted common shares with a grant date fair value of $15.24 . 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 $1.7 million and $1.9 million for the quarters ended June 30, 2017 and 2016 , and $2.6 million and $3.2 million for the six months ended June 30, 2017 and 2016 , respectively, was recognized in compensation expense relating to stock benefit plans. At June 30, 2017 there was compensation expense of $4.7 million to be recognized for awarded but unvested stock options and $18.5 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. At June 30, 2017 the Company had no liability for unrecognized tax benefits. The Company recognizes interest accrued related to: (1) unrecognized tax benefits in other expenses and (2) refund claims in other operating income, and penalties (if any) in other expenses. 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, 2016 , 2015 , 2014 and 2013 . Impact of New Accounting Standards In May 2014 the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-9, “Revenue from Contracts with Customers (Topic 606)”. This guidance supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. The core principle of this guidance requires an entity to recognize revenue upon the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and provides five steps to be analyzed to accomplish the core principle. This guidance is effective retrospectively for annual reporting periods beginning after December 15, 2017, including interim periods within those years and early adoption is not permitted. We are continuing our overall assessment of revenue streams and reviewing contracts potentially affected by this guidance and other revenue streams associated with contracts with third parties to determine the potential impact to our results of operations, financial position, and disclosures. In January 2016 the FASB issued ASU 2016-01, “Financial Instruments-Overall (Subtopic 825-10)” . This guidance requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Additionally, this guidance requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. This guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We do not believe this standard will have a material impact on our results of operations and financial position. In February 2016 the FASB issued ASU 2016-2, “Leases” . This guidance requires a lessee to recognize in the statement of financial condition a liability to make lease payments and a right-of-use asset representing the right to use the underlying asset for the term of the lease. Optional periods should only be recognized if the lessee is reasonably certain to exercise the option. For leases with a term of twelve months or less, the lessee is permitted not to recognize lease assets and lease liabilities and should recognize lease expense for such leases generally on a straight-line basis over the term of the lease. This guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those years and early adoption is permitted. We are currently evaluating the impact this standard will have on our results of operations and financial position. In March 2016 the FASB issued ASU 2016-08, “Principal Versus Agent Considerations” . This guidance clarifies the implementation guidance on principal versus agent considerations of ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)" . When another party is involved in providing goods or services to a customer, an entity is required to determine whether the nature of its promise is to provide the specified good or service itself (that is, the entity is a principal) or to arrange for that good or service to be provided by the other party (that is, the entity is an agent). When (or as) an entity that is a principal satisfies a performance obligation, the entity recognizes revenue in the gross amount of consideration to which it expects to be entitled in exchange for the specified good or service transferred to the customer. When (or as) an entity that is an agent satisfies a performance obligation, the entity recognizes revenue in the amount of any fee or commission to which it expects to be entitled in exchange for arranging for the specified good or service to be provided by the other party. This guidance is effective retrospectively for annual reporting periods beginning after December 15, 2017, including interim periods within those years and early adoption is not permitted. We are currently evaluating the impact this standard will have on our results of operations and financial position. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326)-Measurement of Credit Losses on Financial Instruments , which eliminates the probable initial recognition threshold for credit losses requiring, instead, that all financial assets (or group of financial assets) measured at amortized cost be presented at the net amount expected to be collected inclusive of the entity’s current estimate of all lifetime expected credit losses. This guidance also applies to certain off-balance-sheet credit exposures such as unfunded commitments and non-derivative financial guarantees. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) in order to present the net carrying value at the amount expected to be collected on the financial asset. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The income statement under this guidance will reflect the initial recognition of current expected credit losses for newly recognized assets, as well as any increases or decreases of expected credit losses that have occurred during the period. This guidance retains many currently-existing disclosures related to the credit quality of an entity’s assets and the related allowance for credit losses amended to reflect the change to an expected credit loss methodology, as well as enhanced disclosures to provide information to users at a more disaggregated level. Upon adoption, ASU 2016-13 provides for a modified retrospective transition by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is effective, except for debt securities for which an other-than-temporary impairment has previously been recognized. For these debt securities, a prospective transition is provided in order to maintain the same amortized cost prior to and subsequent to the effective date of the ASU. This guidance is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those annual periods with early adoption permitted for fiscal years beginning after December 15, 2018, and interim periods within those annual periods. We are currently evaluating the impact this standard will have on our results of operations and financial position. In January 2017 the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" . This guidance eliminates the requirement to determine the fair value of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under this guidance goodwill impairment testing will be performed by comparing the fair value of the reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. This guidance is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and should be applied on a prospective basis. We are currently evaluating the impact this standard will have on our results of operations and financial position. In March 2017, the FASB issued ASU No. 2017-07, “Compensation Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Costs and Net Periodic Postretirement Benefit Costs. This guidance provides financial statement users with clearer and disaggregated information related to the components of net periodic benefit cost and improve transparency of the presentation of net periodic benefit cost in the financial statements. This guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted and this guidance should be applied retrospectively. We are currently evaluating the impact this standard will have on our results of operations and financial position. In March 2017 the FASB issued ASU 2017-08, "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities" . This guidance shortens the amortization period for certain callable debt securities held at a premium to the earliest call date from the maturity date. This guidance is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted in any interim period. We are currently evaluating the impact this standard will have on our results of operations and financial position.

Segment Reporting [Abstract]
Business Segments	Business Segments We previously operated 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 was comprised of Northwest Consumer Discount Company ("NCDC"), a subsidiary of Northwest offered personal installment loans for a variety of consumer and real estate products. This activity was funded primarily through an intercompany borrowing relationship with Allegheny Services, Inc., a subsidiary of Northwest. As previously announced, all NCDC offices were closed on July 14, 2017; this closure eliminates our consumer finance segment. 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.

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 and ability 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. Credit related impairment on all debt securities is recognized in earnings while noncredit related 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 and six months ended June 30, 2017 (in thousands): 2017 2016 Beginning balance at April1, (1) $ 7,942 8,424 Credit losses on debt securities for which other-than-temporary impairment was not previously recognized — — Reduction for losses realized during the quarter — (16 ) Reduction for securities sold/ called realized during the quarter — — Additional credit losses on debt securities for which other-than-temporary impairment was previously recognized — — Ending balance at June 30, $ 7,942 8,408 (1) The beginning balance represents credit losses included in other-than-temporary impairment charges recognized on debt securities in prior periods 2017 2016 Beginning balance at January 1, (1) $ 7,942 8,436 Credit losses on debt securities for which other-than-temporary impairment was not previously recognized — — Reduction for losses realized during the quarter — (28 ) Reduction for securities sold/ called realized during the nine months — — Additional credit losses on debt securities for which other-than-temporary impairment was previously recognized — — Ending balance at June 30, $ 7,942 8,408 (1) The beginning balance represents credit losses included in other-than-temporary impairment charges recognized on debt securities in prior periods.

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 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.

Therefore, we are accreting the difference between the carrying value and their expected cash flows into interest income. 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 complet

Guarantees [Abstract]
Guarantees	Guarantees 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 June 30, 2017 , the maximum potential amount of future payments we could be required to make under these non-recourse standby letters of credit was $25.9 million , of which $17.2 million is fully collateralized. At June 30, 2017 , we had a liability, which represents deferred income, of $170,000 related to the standby letters of credit.

Earnings Per Share [Abstract]
Earnings Per Share	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 June 30, 2017 and 2016, were included in the computation of diluted earnings per share because the options’ exercise price was less than the average market price of the common shares of $15.97 and $14.15 , respectively. All stock options outstanding during the six months ended June 30, 2017 were included in the computation of diluted earnings per share because the options’ exercise price was less than the average market price of the common shares of $ 16.75 .Stock options to purchase 723,459 shares of common stock with a weighted average exercise price of $14.15 per share were outstanding during the six months ended June 30, 2016 but were not included in the computation of diluted earnings per share because the options’ exercise price was greater than the average market price of the common shares of $13.43 . The computation of basic and diluted earnings per share follows (in thousands, except share data and per share amounts): Quarter ended Six Months Ended 2017 2016 2017 2016 Reported net income/ (loss) $ 30,982 (7,008 ) 48,728 10,976 Weighted average common shares outstanding 100,950,772 99,177,609 100,798,209 99,033,676 Dilutive potential shares due to effect of stock options 1,498,921 1,065,833 1,726,849 778,049 Total weighted average common shares and dilutive potential shares 102,449,693 100,243,442 102,525,058 99,811,725 Basic earnings per share: $ 0.31 (0.07 ) 0.48 0.11 Diluted earnings per share: $ 0.30 (0.07 ) 0.48 0.11

Fair Value Disclosures [Abstract]
Disclosures About Fair Value of Financial Instruments	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 Held for Sale The estimated fair value of loans held for sale is based on market bids obtained from potential buyers. Loans Held for Investment 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. Federal Home Loan Bank (“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 collateralized borrowings 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 June 30, 2017 and December 31, 2016 , there was no significant unrealized appreciation or depreciation on these financial instruments.

The following table represents the fair value measurement for nonrecurring assets at December 31, 2016 (in thousands): Level 1 Level 2 Level 3 Total assets at fair value Loans measured for impairment $ — — 41,933 41,933 Mortgage loan servicing $ — — 246 246 Real estate owned — — 4,889 4,889 Total assets $ — — 47,068 47,068 Impaired loans — A loan is considered to be impaired as described in Note 1 of the Notes to Consolidated Financial Statements in Item 8 of Part II of our 2016 Annual Report on Form 10-K. We classify loans individually evaluated for impairment that require a specific reserve as nonrecurring Level 3. Mortgage servicing rights - Mortgage servicing rights represent the value of servicing residential mortgage loans, when the mortgage loans have been sold into the secondary market and the associated servicing has been retained. The value is determined through a discounted cash flow analysis, which uses interest rates, prepayment speeds and delinquency rate assumptions as inputs. All of these assumptions require a significant degree of management judgment. Servicing rights and the related mortgage loans are segregated into categories or homogeneous pools based upon common characteristics. Adjustments are only made when the estimated discounted future cash flows are less than the carrying value, as determined by individual pool. As such, mortgage servicing rights are classified 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 June 30, 2017 (dollar amounts in thousands): Fair value Valuation techniques Significant unobservable inputs Range (weighted average) Debt securities $ 10,638 Discounted cash Discount margin 0.4% to 2.1% (0.7%) flow Default rates 1.0% Prepayment speeds 1.0 annually Loans measured for impairment 40,908 Appraisal value (1) Estimated cost to sell 10.0% Discounted cash flow Discount rate 4.25% to 10.0% (7.50%) Mortgage servicing rights 131 Discounted cash Annual service cost $80 flow Prepayment rates 9.4% to 15.6% (11.2%) Expected life (months) 67.25 to 47.14 (60.9) Option adjusted spread 800 basis points Forward yield curve 1.05% to 2.1% (1.5%) Real estate owned 6,030 Appraisal value (1) Estimated cost to sell 10.0% (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.

Guaranteed Preferred Beneficial Interests in Company's Junior Subordinated Deferrable Interest Debentures (Trust-Preferred Securities) and Derivatives
Guaranteed Preferred Beneficial Interests in the Company's Junior Subordinated Deferrable Interest Debentures (Trust Preferred Securities) and Derivatives	Guaranteed Preferred Beneficial Interests in the Company’s Junior Subordinated Deferrable Interest Debentures (Trust Preferred Securities) and Derivatives We have two legacy 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 distributions 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. As a result of the LNB acquisition we acquired two statutory business trusts: LNB Trust I and LNB Trust II; both are Delaware statutory business trusts. The outstanding stock issued by LNB Trust I was redeemed on December 15, 2015. At June 30, 2017 , LNB Trust II had 7,875 cumulative trust preferred securities outstanding (liquidation value of $1,000 per preferred security or $7,875,000 ) with a stated maturity of June 15, 2037. These securities carry a floating interest rate, which is reset quarterly, equal to three-month LIBOR plus 1.48% . LNB Trust II invested the proceeds of the offerings in junior subordinated deferrable interest debentures acquired by the Company. The structure of these debentures mirrors the structure of the trust-preferred securities. LNB Trust II holds $8,119,000 of junior subordinated debentures. The subordinated debentures are the sole assets of the Trusts. Cash distributions on the trust securities are made on a quarterly basis to the extent interest on the debentures is received by the Trusts. Derivatives Designated as Hedging Instruments We are currently a counterparty to two 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 swap modifies the re-pricing characteristics of Trust IV, wherein for a ten year period expiring in December 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 June 30, 2017 , $ 2.6 million of cash was pledged as collateral to the counterparty. At June 30, 2017 , the fair value of the swap agreements was $(1.9) 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. Derivatives Not Designated as Hedging Instruments We are currently a counterparty to foreign exchange contracts, which include spot and forward contracts, which are commitments to buy or sell foreign currency at an agreed-upon price on an agreed-upon settlement date. We use these instruments on a limited basis to eliminate exposure to fluctuations in currency exchange rates on certain commercial loans that are denominated in foreign currencies. As a result of fluctuations in foreign currencies, the U.S. dollar-equivalent value of the foreign currency denominated loans increase or decrease. Gains or losses on the foreign exchange contracts substantially offset the translation gains and losses on the related foreign currency denominated loans. The following table sets forth information related to derivatives at June 30, 2017 and December 31, 2016 (in thousands): June 30, December 31, Derivatives designed as hedging instruments: Fair value adjustment (1) $ 1,934 2,736 Notional amount 50,000 50,000 Collateral posted 2,555 3,005 Derivatives not designed as hedging instruments: Foreign exchange adjustment (2) (85 ) — Notional amount 4,324 — (1) Included in other liabilities.

Legal Proceedings	Legal Proceedings 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 June 30, 2017 we have not accrued for any legal proceedings based on our analysis of currently available information which 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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. At June 30, 2017 the Company had no liability for unrecognized tax benefits. The Company recognizes interest accrued related to: (1) unrecognized tax benefits in other expenses and (2) refund claims in other operating income, and penalties (if any) in other expenses. 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, 2016 , 2015 , 2014
Impact of New Accounting Standards	Impact of New Accounting Standards In May 2014 the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-9, “Revenue from Contracts with Customers (Topic 606)”. This guidance supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. The core principle of this guidance requires an entity to recognize revenue upon the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and provides five steps to be analyzed to accomplish the core principle. This guidance is effective retrospectively for annual reporting periods beginning after December 15, 2017, including interim periods within those years and early adoption is not permitted. We are continuing our overall assessment of revenue streams and reviewing contracts potentially affected by this guidance and other revenue streams associated with contracts with third parties to determine the potential impact to our results of operations, financial position, and disclosures. In January 2016 the FASB issued ASU 2016-01, “Financial Instruments-Overall (Subtopic 825-10)” . This guidance requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Additionally, this guidance requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. This guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We do not believe this standard will have a material impact on our results of operations and financial position. In February 2016 the FASB issued ASU 2016-2, “Leases” . This guidance requires a lessee to recognize in the statement of financial condition a liability to make lease payments and a right-of-use asset representing the right to use the underlying asset for the term of the lease. Optional periods should only be recognized if the lessee is reasonably certain to exercise the option. For leases with a term of twelve months or less, the lessee is permitted not to recognize lease assets and lease liabilities and should recognize lease expense for such leases generally on a straight-line basis over the term of the lease. This guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those years and early adoption is permitted. We are currently evaluating the impact this standard will have on our results of operations and financial position. In March 2016 the FASB issued ASU 2016-08, “Principal Versus Agent Considerations” . This guidance clarifies the implementation guidance on principal versus agent considerations of ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)" . When another party is involved in providing goods or services to a customer, an entity is required to determine whether the nature of its promise is to provide the specified good or service itself (that is, the entity is a principal) or to arrange for that good or service to be provided by the other party (that is, the entity is an agent). When (or as) an entity that is a principal satisfies a performance obligation, the entity recognizes revenue in the gross amount of consideration to which it expects to be entitled in exchange for the specified good or service transferred to the customer. When (or as) an entity that is an agent satisfies a performance obligation, the entity recognizes revenue in the amount of any fee or commission to which it expects to be entitled in exchange for arranging for the specified good or service to be provided by the other party. This guidance is effective retrospectively for annual reporting periods beginning after December 15, 2017, including interim periods within those years and early adoption is not permitted. We are currently evaluating the impact this standard will have on our results of operations and financial position. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326)-Measurement of Credit Losses on Financial Instruments , which eliminates the probable initial recognition threshold for credit losses requiring, instead, that all financial assets (or group of financial assets) measured at amortized cost be presented at the net amount expected to be collected inclusive of the entity’s current estimate of all lifetime expected credit losses. This guidance also applies to certain off-balance-sheet credit exposures such as unfunded commitments and non-derivative financial guarantees. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) in order to present the net carrying value at the amount expected to be collected on the financial asset. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The income statement under this guidance will reflect the initial recognition of current expected credit losses for newly recognized assets, as well as any increases or decreases of expected credit losses that have occurred during the period. This guidance retains many currently-existing disclosures related to the credit quality of an entity’s assets and the related allowance for credit losses amended to reflect the change to an expected credit loss methodology, as well as enhanced disclosures to provide information to users at a more disaggregated level. Upon adoption, ASU 2016-13 provides for a modified retrospective transition by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is effective, except for debt securities for which an other-than-temporary impairment has previously been recognized. For these debt securities, a prospective transition is provided in order to maintain the same amortized cost prior to and subsequent to the effective date of the ASU. This guidance is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those annual periods with early adoption permitted for fiscal years beginning after December 15, 2018, and interim periods within those annual periods. We are currently evaluating the impact this standard will have on our results of operations and financial position. In January 2017 the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" . This guidance eliminates the requirement to determine the fair value of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under this guidance goodwill impairment testing will be performed by comparing the fair value of the reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. This guidance is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and should be applied on a prospective basis. We are currently evaluating the impact this standard will have on our results of operations and financial position. In March 2017, the FASB issued ASU No. 2017-07, “Compensation Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Costs and Net Periodic Postretirement Benefit Costs. This guidance provides financial statement users with clearer and disaggregated information related to the components of net periodic benefit cost and improve transparency of the presentation of net periodic benefit cost in the financial statements. This guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted and this guidance should be applied retrospectively. We are currently evaluating the impact this standard will have on our results of operations and financial position. In March 2017 the FASB issued ASU 2017-08, "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities" . This guidance shortens the amortization period for certain callable debt securities held at a premium to the earliest call date from the maturity date. This guidance is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted in any interim period. We are currently evaluating the impact this standard will have on our results of operations and financial position.
