NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)


(1)	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 182 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 Capital Group, Inc., Allegheny Services, Inc., Great Northwest Corporation, and The Bert Company (doing business as Northwest Insurance Services). 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, 2018 updated, as required, for any new pronouncements or changes.

Certain items previously reported have been reclassified to conform to the current year's reporting format.

The results of operations for the quarter and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019, or any other period.

Stock-Based Compensation

On May 22, 2019, the Company awarded employees 547,410 stock options and directors 64,800 stock options with an exercise price of $17.27 and grant date fair value of $1.14 per stock option, and the Company awarded employees 256,800 restricted common shares and directors 24,300 restricted common shares with a grant date fair value of $17.27. Awarded stock options and common shares vest over a seven-year period with the first vesting occurring on the grant date. Stock-based compensation expense of $1.7 million and $1.3 million for the quarters ended September 30, 2019 and 2018, and $5.4 million and $4.5 million for the nine months ended September 30, 2019 and 2018, respectively, was recognized in compensation expense relating to our stock benefit plans. At September 30, 2019, there was compensation expense of $3.8 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 September 30, 2019 we had no liability for unrecognized tax benefits.

We recognize interest accrued related to: (1) unrecognized tax benefits in other expenses and (2) refund claims in other operating income. We recognize 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, 2018, 2017 and 2016.

Recent Accounting Pronouncements

(a) Recently Adopted Accounting Standards

In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842), which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Accounting Standards Codification ("ASC") Topic 842 establishes a right of use ("ROU") model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The Company has elected not to recognize ROU assets and lease liabilities for short-term leases of all classes of underlying assets that have a lease term of 12 months or less and recognizes lease expense for these leases on a straight-line basis over the term of the lease.

On January 1, 2019, the Company adopted ASU 2016-02 using a modified retrospective transition approach as of the effective date, January 1, 2019. As a result, the Company was not required to adjust its comparative period financial information for effects of the standard or make the new required lease disclosures for periods before the date of adoption (i.e. January 1, 2017). The Company has elected to adopt the package of transition practical expedients and, therefore, has not reassessed (1) whether existing or expired contracts contain a lease, (2) lease classification for existing or expired leases or (3) the accounting for initial direct costs that were previously capitalized. The Company also elected the practical expedient to use hindsight for leases existing at the adoption date.

As a result of the adoption of ASU 2016-02, we recognized an operating lease ROU asset of approximately $40.2 million, an operating lease liability of approximately $42.2 million and a cumulative-effect adjustment on retained earnings of $1.2 million on the consolidated statements of financial condition as of January 1, 2019, with no impact on our consolidated statement of income or consolidated statement of cash flows compared to the prior lease accounting model.

(b) Recently Issued Accounting Standards

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 and instead requires 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 assets 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 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.

Management has created a formal working group to govern the implementation of these amendments, consisting of key stakeholders from finance, risk, credit and accounting. The working group meets periodically to discuss the progress of implementations, monitor the established timeline and discuss latest hot topics and industry trends. We have engaged with a third party to assist in the development of certain portfolio-level estimation methodologies and have chosen, and are in the process of implementing, a third-party software platform provider. We have finalized and documented the portfolio segmentation and methodologies that will be utilized. The model validation process has begun. Management has made decisions on reasonable and supportable forecast period and reversion method. Management is currently developing controls, processes, policies and disclosures in preparation for performing a full end to end parallel run. We are also evaluating the effect this guidance will have on our results of operations, financial position and related disclosures. The impact of the ASU will depend upon the state of the economy and the nature of our portfolios, among other items, at the date of adoption.

Table of Contents

In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement.” This guidance removes, modifies and adds disclosure requirements for fair value measurements. This guidance is effective for annual periods beginning after December 15, 2019, including interim periods within those years, with early adoption permitted for any removed or modified disclosure requirements. Transition is on a prospective basis for the new and modified disclosures, and on a retrospective basis for disclosures that have been eliminated. We do not expect this guidance to have a material impact on our financial statements.

In August 2018, the FASB issued ASU 2018-14, “Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20) - Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans.” This guidance removes and adds disclosure requirements for defined benefit pension or other post-retirement plans. This guidance is effective for annual periods beginning after December 15, 2020, with early adoption permitted, and requires retrospective adoption for all periods presented. We do not expect this guidance to have a material impact on our financial statements.

In August 2018, the FASB issued ASU 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” This guidance aligns the requirements for capitalization of implementation costs incurred in a hosting arrangement that is a service contract with the existing guidance for internal-use software. This guidance is effective for annual periods beginning after December 15, 2019, including interim periods within those years, with early adoption permitted. Transition can either be on a retrospective basis or a prospective basis on all implementation costs incurred after the date of adoption. We will apply this guidance on a prospective basis upon adoption and do not expect it to have a material impact on our financial statements.

(2) Acquisition

On March 8, 2019, the Company completed the merger with Donegal Financial Services Corporation ("DFSC"), the holding company for Union Community Bank ("UCB"), for total consideration of $85.8 million. The transaction has expanded Northwest’s franchise by 12 offices in Lancaster County in eastern Pennsylvania. The result of UCB's operations are included in the Consolidated Statements of Income from the date of acquisition.

Under the terms of the merger agreement, the two shareholders of DFSC, Donegal Mutual Insurance Company and Donegal Group Inc., received payment in the form of 50% cash and 50% stock, or a total of $42.5 million and 2,462,373 shares of common stock of the Company, valued at $43.3 million, based on the $17.58 closing price of the Company's stock on March 8, 2019.

(1) Amounts are estimates and subject to adjustment. Actual amounts are not expected to differ materially from the amounts shown.

We estimated the fair value of loans acquired from UCB by utilizing a methodology wherein similar loans were aggregated into pools. Cash flows for each pool were determined by estimating future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value based on a market rate for similar loans. There was no carryover of UCB’s allowance for

loan losses associated with the loans we acquired as the loans were initially recorded at fair value. Loans acquired with evidence of credit quality deterioration were evaluated and not considered to be significant.

The core deposit intangible asset recognized as part of the UCB merger is being amortized over its estimated useful life of seven years utilizing an accelerated method. The goodwill, which is not amortized for book purposes, was assigned to our Community Banking segment and is not deductible for tax purposes. The fair values of savings and transaction deposit accounts acquired from UCB were assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. Certificates of deposit were valued by projecting out the expected cash flows based on the contractual terms of the certificates of deposit. These cash flows were discounted based on a market rate for a certificate of deposit with a corresponding maturity.

Direct costs related to the UCB merger were expensed as incurred and were $3.1 million during the nine months ended September 30, 2019, which includes technology and communications costs, professional services, marketing and advertising, and other noninterest expenses.

(3) Leases

At inception, the Company determines if an arrangement contains a lease and whether that lease meets the classification of a finance or operating lease. Operating lease ROU assets represent our right to use an underlying asset during the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments. ROU assets are further adjusted for lease incentives and initial direct costs.

The Company has operating leases for certain branch and office facilities or land with lease terms up to 35 years. These leases generally contain renewal options for periods ranging from one to ten years. These options are included in the lease term when it is reasonably certain that the options will be exercised.

Some of the Company’s lease arrangements contain lease components (e.g., minimum rent payments) and non-lease components (e.g., common area maintenance, taxes, etc.). The Company elected the option of not separating lease and non-lease components and instead we account for them as a single lease component.

Certain lease agreements include rental payments that are adjusted periodically for an index or rate. The leases are initially measured using the projected adjustment for the index or rate in effect at the commencement date. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Generally, the Company cannot practically determine the interest rate implicit in the lease. Therefore, the Company uses its incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms.

Lease expense for these leases is recognized on a straight-line basis over the lease term, with variable lease payments recognized in the period those payments are incurred. The components of lease cost recognized within our consolidated statements of income were as follows (in thousands):



	For the quarter ended September 30, 2019		For the nine months ended September 30, 2019

We review our investment portfolio 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 and ability to hold the investments for a period of time sufficient to allow for a recovery in value. We do not have the intent to sell these securities and it is more likely than not that we will not have to sell these securities before a recovery of our cost basis. For these reasons, we consider the unrealized losses to be temporary impairment losses.

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 quarters ended September 30, (in thousands):

At September 30, 2019, we expect to fully collect the carrying value of our purchased credit impaired loans and have determined that we can reasonably estimate their future cash flows including those loans that are 90 days or more delinquent. As a result, we do not consider our purchased credit impaired loans that are 90 days or more delinquent to be nonaccrual or impaired and continue to recognize interest income on these loans, including the loans’ accretable discount.

Table of Contents

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 period of at least nine 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 premiums or discounts), 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 in accordance with 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.

Table of Contents

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.

As of September 30, 2019, there were no events or changes in circumstances that would cause us to update that goodwill impairment test.

(7) Borrowed Funds

(a) Borrowings

Borrowings from the Federal Home Loan Bank of Pittsburgh ("FHLB"), are secured by our residential first mortgage and other qualifying loans. Certain of these borrowings are subject to restrictions or penalties in the event of prepayment.

The revolving line of credit with the FHLB carries a commitment of $250.0 million. The rate is adjusted daily by the FHLB, and any borrowings on this line may be repaid at any time without penalty. At September 30, 2019 and December 31, 2018, the balance of the revolving line of credit was $172.2 million and $128.6 million, respectively.

At September 30, 2019 and December 31, 2018, collateralized borrowings due within one year were $83.1 million and $105.8 million, respectively. These borrowings are collateralized by cash or various securities held in safekeeping by the FHLB.

(b) Trust Preferred Securities

Prior to our merger with DFSC, we owned three statutory business trusts: Northwest Bancorp Capital Trust III, a Delaware statutory business trust, Northwest Bancorp Statutory Trust IV, a Connecticut statutory business trust and LNB Trust II, a Delaware statutory business trust (the Trusts). The 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 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 issued 50,000 cumulative trust preferred securities in a private transaction to a pooled investment vehicle on December 5, 2005 (liquidation value of $1,000 per preferred security or $50,000,000) with a stated maturity of December 30, 2035 and a floating rate of interest, which is reset quarterly, equal to three-month LIBOR plus 1.38%. Northwest Bancorp Statutory Trust IV issued 50,000 cumulative trust preferred securities in a private transaction to a pooled investment vehicle on December 15, 2005 (liquidation value of $1,000 per preferred security or $50,000,000) with a stated maturity of December 15, 2035 and a floating rate of interest, which is reset quarterly, equal to three-month LIBOR plus 1.38%. LNB Trust II has 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 and a floating rate of interest, which resets quarterly,

Table of Contents

equal to three-month LIBOR plus 1.48%. As the shareholders of the trust preferred securities are the primary beneficiaries of the Trusts, the Trusts are not consolidated in our financial statements.

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. Northwest Bancorp Capital Trust III holds $51,547,000 of the Company’s junior subordinated debentures due December 30, 2035 with a floating rate of interest, reset quarterly, of three-month LIBOR plus 1.38%. The rate in effect at September 30, 2019 was 3.48%. Northwest Bancorp Statutory Trust IV holds $51,547,000 of the Company’s junior subordinated debentures due December 15, 2035 with a floating rate of interest, reset quarterly, of three-month LIBOR plus 1.38%. The rate in effect at September 30, 2019 was 3.50%. LNB Trust II holds $8,119,000 of the Company's junior subordinated debentures due June 15, 2037, with a floating rate of interest, reset quarterly, of three-month LIBOR plus 1.48%. The rate in effect at September 30, 2019 was 3.60%.

As a result of the merger with DFSC, we acquired two additional statutory business trusts: Union National Capital Trust I ("UNCT I") and Union National Capital Trust II ("UNCT II"); both are Delaware statutory business trusts. At September 30, 2019, UNCT I had 8,000 cumulative trust preferred securities outstanding (liquidation value of $1,000 per preferred security or $8,000,000) with a stated maturity of December 19, 2034. These securities carry a floating interest rate, which is reset quarterly, equal to three-month LIBOR plus 2.85%. At September 30, 2019, UNCT II had 3,000 cumulative trust preferred securities outstanding (liquidation value of $1,000 per preferred security or $3,000,000) with a stated maturity of October 14, 2034. These securities carry a floating interest rate, which is reset quarterly, equal to three-month LIBOR plus 2.00%. The Trusts have invested the proceeds of the offerings in junior subordinated deferrable interest debentures held by the Company. The structure of these debentures mirrors the structure of the trust-preferred securities. UNCT I holds $8,248,000 of junior subordinated debentures and UNCT II holds $3,093,000 of junior subordinated debentures. These subordinated debentures are the sole assets of the Trusts. As the shareholders of the trust preferred securities are the primary beneficiaries of the Trusts, the Trusts are not consolidated in our financial statements.

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 securities also are deferred. To date there have been no interest deferrals. Interest on the subordinated debentures and distributions on the trust securities is cumulative. Our obligation constitutes a full, irrevocable, and unconditional guarantee on a subordinated basis of the obligations of the trust under the preferred securities.

The Trusts must redeem the preferred securities when the debentures are paid at maturity or upon an earlier redemption of the debentures to the extent the debentures are redeemed. All or part of the debentures may be redeemed at any time. Also, the debentures may be redeemed at any time if existing laws or regulations, or the interpretation or application of these laws or regulations, change causing:


•	the interest on the debentures to no longer be deductible by the Company for federal income tax purposes;


•	the trust to become subject to federal income tax or to certain other taxes or governmental charges;


•	the trust to register as an investment company; or


•	the preferred securities do not qualify as Tier I capital.

We may, at any time, dissolve any of the Trusts and distribute the debentures to the trust security holders, subject to receipt of any required regulatory approval.


(8)	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 September 30, 2019, the maximum potential amount of future payments we could be required to make under these non-recourse standby letters of credit was $39.6 million, of which $32.8 million is fully collateralized. At September 30, 2019, we had a liability, which represents deferred income, of $331,000 related to the standby letters of credit.

Table of Contents

(9) 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 September 30, 2019 and 2018 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 $16.69 and $18.01, respectively. All stock options outstanding during the nine months ended September 30, 2019 and 2018 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 $17.19 and $17.30, respectively.

The following table sets forth the computation of basic and diluted EPS (in thousands, except share data and per share amounts):

(11)	Disclosures About Fair Value of Financial Instruments

We are required to disclose fair value information about financial instruments whether or not recognized in the consolidated statement of financial condition. Fair value information of certain financial instruments and all nonfinancial instruments is not required to be disclosed. 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 and cash equivalents, marketable securities available-for-sale, accrued interest receivable, interest rate lock commitments, forward commitments, interest rate swaps, savings and checking deposits and accrued interest payable.

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.

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

The fair value of the loans held of investment is estimated using a discounted cash flow analysis that utilizes interest rates currently being offered for similar loans adjusted for liquidity and credit risk.

Table of Contents

FHLB stock

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

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.

Interest rate lock commitments and forward commitments

The fair value of interest rate lock commitments is based on the value of underlying loans held-for-sale which is based on quoted prices for similar loans in the secondary market. This value is then adjusted based on the probability of the loan closing (i.e. the “pull-through” amount, a significant unobservable input). The fair value of forward sale commitments is based on quoted prices from the secondary market based on the settlement date of the contracts.

Cash flow hedges, interest rate and foreign exchange swap agreements

The fair value of the interest rate swaps is based upon the present value of the expected future cash flows using the LIBOR swap curve, the basis for the underlying interest rate. To price interest rate swaps, cash flows are first projected for each payment date using the fixed rate for the fixed side of the swap and the forward rates for the floating side of the swap. These swap cash flows are then discounted to time zero using LIBOR zero-coupon interest rates. The sum of the present value of both legs is the fair market value of the interest rate swap. These valuations have been derived from our third party vendor’s proprietary models rather than actual market quotations. The proprietary models are based upon financial principles and assumptions that we believe to be reasonable. The fair value of the foreign exchange swap is derived from proprietary models rather than actual market quotations. The proprietary models are based upon financial principles and assumptions we believe to be reasonable.

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, 2019 and December 31, 2018, there was no significant unrealized appreciation or depreciation on these financial instruments.

Real estate owned, net	—		—	2,498	2,498
Total assets	$	—	—	42,831	42,831

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 2018 Annual Report on Form 10-K. We classify loans individually evaluated for impairment that require a specific reserve as nonrecurring Level 3.

Real estate owned - Real estate owned is comprised of property acquired through foreclosure or voluntarily conveyed by 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 real estate owned as nonrecurring Level 3.

The following 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, 2019 (in thousands):



	Fair value		Valuation techniques	Significant unobservable inputs	Range (weighted average)
Loans measured for impairment	$	40,603	Appraisal value (1)	Estimated cost to sell	10.0%
			Discounted cash flow	Discount rate	4.25% to 11.0% (7.50%)

Real estate owned	$	1,237	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.

(12) Derivative Financial Instruments

We are a party to derivative financial instruments in the normal course of business to manage our own exposure to fluctuations in interest rates and to meet the needs of our customers. The primary derivatives that we use are interest rate swaps and caps and foreign exchange contracts, which are entered into with counterparties that meet established credit standards. We believe that the credit risk inherent in all of our derivative contracts is minimal based on our credit standards and the netting and collateral provisions of the interest rate swap agreements.

Derivatives Designated as Hedging Instruments

With the expiration of the $50.0 million in notional of interest rate swap agreements (swaps) previously designated in hedging relationships, we are no longer a counterparty to any interest rate swap agreements designated as cash flow hedges. Previously, the swaps were intended to protect against the variability of cash flows associated with Northwest Bancorp Capital Trust III and Northwest Bancorp Capital Trust IV. In 2018, the swaps matured without replacement.

Table of Contents

Derivatives Not Designated as Hedging Instruments

We act as an interest rate or foreign exchange swap counterparty for certain commercial borrowers in the normal course of servicing our customers, which are accounted for at fair value. We manage our exposure to such interest rate or foreign exchange swaps by entering into corresponding and offsetting interest rate swaps with third parties that mirror the terms of the swaps we have with the commercial borrowers. These positions (referred to as “customer swaps”) directly offset each other and our exposure is the fair value of the derivatives due to changes in credit risk of our commercial borrowers and third parties. Customer swaps are recorded within other assets or other liabilities on the consolidated statement of financial condition at their estimated fair value. Changes to the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the consolidated statement of income.

We enter into interest rate lock commitments for residential mortgage loans which commit us to lend funds to a potential borrower at a specific interest rate within a specified period of time. Interest rate lock commitments that relate to the origination of mortgage loans that will be held-for-sale are considered derivative financial instruments under applicable accounting guidance. Interest rate lock commitments on loans held-for-sale are carried at fair value in other assets on the consolidated statement of financial condition. Northwest sells loans to the secondary market on a mandatory or best efforts basis. The loans sold on a mandatory basis commit us to deliver a specific principal amount of mortgage loans to an investor at a specified price, by a specified date, or the commitment must be paired off. These forward commitments entered into on a mandatory delivery basis meet the definition of a derivative financial instrument. All closed loans to be sold on a mandatory delivery basis are classified as held-for-sale on the consolidated statement of financial condition. Changes to the fair value of the interest rate lock commitments and the forward commitments are recorded in mortgage banking income in the consolidated statements of income.

(13) 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 September 30, 2019, 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.

During the year-ended December 31, 2018, Northwest and our subsidiary, Northwest Insurance Services (“NWIS”), were involved in a lawsuit against, among others, First National Bank of Pennsylvania (“FNB”) and their insurance subsidiary, First National Insurance Agency, LLC (“FNIA”). All counterclaims against Northwest were discontinued and, on December 21, 2018, a verdict was rendered in favor of NWIS on several of its claims. Post-trial proceedings have concluded with the verdict affirmed and attorneys’ fees awarded. An appeal has been filed with the Pennsylvania Superior Court. Due to the inherent uncertainties with respect to these proceedings, we have not accrued any awards associated with this verdict within our consolidated financial statements as of September 30, 2019.

Overview of Critical Accounting Policies Involving Estimates

Please refer to Note 1 of the Notes to Consolidated Financial Statements in Item 8 of Part II of our 2018 Annual Report on Form 10-K.

Comparison of Financial Condition

On March 8, 2019, we acquired all of the outstanding common shares of Donegal Financial Services Corporation ("DFSC"), the holding company for Union Community Bank ("UCB"), for total consideration of $85.8 million, and thereby acquired UCB's 12 branch locations in Lancaster County in eastern Pennsylvania. As a result, we acquired assets with a fair value of $537.9 million, including loans with a fair value of $407.8 million, and we assumed deposits of $479.4 million. Under the terms of the merger agreement, the two shareholders of DFSC, Donegal Mutual Insurance Company and Donegal Group Inc., received payment in the form of 50% cash and 50% stock, or a total of $42.5 million and 2,462,373 shares of NWBI common stock.

Total assets at September 30, 2019 were $10.580 billion, an increase of $972.7 million, or 10.1%, from $9.608 billion at December 31, 2018. This increase in assets was due primarily to the addition of $627.4 million, at fair value, of assets related to the UCB acquisition and organic loan growth of $392.7 million.

Table of Contents

Total loans receivable increased by $800.6 million, or 9.9%, to $8.852 billion at September 30, 2019, from $8.051 billion at December 31, 2018. This increase was due primarily to the addition of $407.8 million, at fair value, of loans related to the UCB acquisition. Additionally, originated loans receivable increased by $392.7 million, or 4.9% .

Total deposits increased by $787.3 million, or 10.0%, to $8.682 billion at September 30, 2019 from $7.894 billion at December 31, 2018 primarily due to the addition of $479.4 million of deposits, at fair value, related to the UCB acquisition. In addition, legacy total deposits increased by $307.9 million, or 3.9%, with increases across all deposit products except for a slight decrease in savings deposits. Legacy interest-bearing demand deposits increased by $132.9 million, or 9.1%, to $1.588 billion at September 30, 2019 from $1.455 billion at December 31, 2018. These increases are due primarily to our continued efforts to attract low cost accounts to whom we can also cross-sell other products and services. Legacy money market deposits also increased $166.4 million, or 10.0%, to $1.828 billion at September 30, 2019 from $1.662 billion at December 31, 2018, and legacy time deposits grew $108.1 million, or 7.7%, to $1.513 billion at September 30, 2019 from $1.405 billion at December 31, 2018.

Total shareholders’ equity at September 30, 2019 was $1.352 billion, or $12.67 per share, an increase of $94.1 million, or 7.5%, from $1.258 billion, or $12.17 per share, at December 31, 2018. This increase in equity was primarily the result of the issuance of 2,462,373 shares of our common stock at $17.58 per share for the UCB acquisition as well as the result of net income of $84.8 million for the nine months ended September 30, 2019. Partially offsetting this increase was the payment of cash dividends of $57.0 million for the nine months ended September 30, 2019.

Regulatory Capital

Financial institutions and their holding companies are subject to various regulatory capital requirements. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by the regulators that, if undertaken, could have a direct, material effect on a company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, financial institutions must meet specific capital guidelines that involve quantitative measures of its assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting guidelines. Capital amounts and classifications are also subject to qualitative judgments made by the regulators about components, risk-weighting and other factors.

In July 2013, the FDIC and the other federal regulatory agencies issued a final rule that revised their leverage and risk-based capital requirements and the method for calculating risk-weighted assets to make them consistent with agreements that were reached by the Basel Committee on Banking Supervision and certain provisions of the Dodd-Frank Act. The rule limits an organization’s capital distributions and certain discretionary bonus payments if the organization does not hold a “capital conservation buffer” consisting of 2.5% of Total, Tier 1 and Common Equity Tier 1 ("CET1") capital to risk-weighted assets in addition to the amount necessary to meet its minimum risk-based capital requirements.

The capital conservation buffer requirement was phased in, which began on January 1, 2016 and ended on January 1, 2019, when the full capital conservation buffer requirement was implemented.

Liquidity

We are required to maintain a sufficient level of liquid assets, as determined by management and reviewed for adequacy by the FDIC and the Pennsylvania Department of Banking and Securities during their regular examinations. Northwest monitors its liquidity position primarily using the ratio of unencumbered available-for-sale liquid assets as a percentage of deposits and borrowings (“liquidity ratio”). Northwest’s liquidity ratio at September 30, 2019 was 9.2%. We adjust liquidity levels in order to meet funding needs for deposit outflows, payment of real estate taxes and insurance on mortgage loan escrow accounts, repayment of borrowings and loan commitments. At September 30, 2019, Northwest had $3.190 billion of additional borrowing capacity available with the FHLB, including $250.0 million on an overnight line of credit, which had a balance of $172.2 million, as well as $43.9 million of borrowing capacity available with the Federal Reserve Bank and $80.0 million with two correspondent banks.

Dividends

We paid $19.2 million and $17.5 million in cash dividends during the quarters ended September 30, 2019 and 2018, respectively. The common stock dividend payout ratio (dividends declared per share divided by net income per diluted share) was 58.1% and 63.0% for the quarters ended September 30, 2019 and 2018, respectively, on dividends of $0.18 per share for the quarter ended September 30, 2019 and on dividends of $0.17 per share for the quarter ended September 30, 2018. We paid $57.0 million and $52.4 million in cash dividends during the nine months ended September 30, 2019 and 2018, respectively. The common stock dividend payout ratio was 67.5% and 67.1% for the nine months ended September 30, 2019 and 2018, respectively, on dividends of $0.54 per share for the nine months ended September 30, 2019 and on dividends of $0.51 per share for the nine months ended September 30, 2018. On October 21, 2019, the Board of Directors declared a cash dividend of $0.18 per share payable on November 15, 2019 to shareholders of record as of November 1, 2019. This represents the 100th consecutive quarter we have paid a cash dividend.

Nonperforming Assets

The following table sets forth information with respect to nonperforming assets. Nonaccrual loans are those loans on which the accrual of interest has ceased. Generally, when a loan is 90 days past due, we fully reverse all accrued interest thereon and cease to accrue interest thereafter. Exceptions are made for loans that have contractually matured, are in the process of being modified to extend the maturity date and are otherwise current as to principal and interest and well-secured loans that are in the process of collection. Loans may also be placed on nonaccrual before they reach 90 days past due if conditions exist that call into question our ability to collect all contractual interest. Other nonperforming assets represent property acquired through foreclosure or repossession. Foreclosed property is carried at the lower of its fair value less estimated costs to sell or the principal balance of the related loan.

Table of Contents

At September 30, 2019, we expect to fully collect the carrying value of our purchased credit impaired loans and have determined that we can reasonably estimate their future cash flows including those loans that are 90 days or more delinquent. As a result, we do not consider these loans that are 90 days or more delinquent, which total $95,000, to be nonaccrual or impaired and continue to recognize interest income on these loans, including the loans’ accretable discount.

A loan is considered to be impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement including both contractual principal and interest payments. The amount of impairment is required to be measured using one of three methods: (1) the present value of expected future cash flows discounted at the loan’s effective interest rate; (2) the loan’s observable market price; or (3) the fair value of collateral if the loan is collateral dependent. If the measure of the impaired loan is less than the recorded investment in the loan, a specific allowance is allocated for the impairment. Impaired loans at September 30, 2019 and December 31, 2018 were $88.8 million and $98.3 million, respectively.

Allowance for Loan Losses

Our Board of Directors has adopted an “Allowance for Loan and Lease Losses” (“ALL”) policy designed to provide management with a systematic methodology for determining and documenting the ALL each reporting period. This methodology was developed to provide a consistent process and review procedure to ensure that the ALL is in conformity with GAAP, our policies and procedures and other supervisory and regulatory guidelines.

On an ongoing basis, the Credit Administration department, as well as loan officers, branch managers and department heads, review and monitor the loan portfolio for problem loans. This portfolio monitoring includes a review of the monthly delinquency reports as well as historical comparisons and trend analysis. Personal and small business commercial loans are classified primarily by delinquency status. In addition, a meeting is held every quarter with each region to monitor the performance and status of commercial loans on an internal watch list. On an on-going basis, the loan officer, in conjunction with a portfolio manager, grades or classifies problem commercial loans or potential problem commercial loans based upon their knowledge of the lending relationship and other information previously accumulated. This rating is also reviewed independently by our Loan Review department on a periodic basis. Our loan grading system for problem commercial loans is consistent with industry regulatory guidelines which classifies loans as “substandard”, “doubtful” or “loss.” Loans that do not expose us to risk sufficient to warrant classification in one of the previous categories, but which possess some weaknesses, are designated as “special mention”. A “substandard” loan is any loan that is 90 days or more contractually delinquent or is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans classified as “doubtful” have all the weaknesses inherent in those classified as “substandard” with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions or values, highly questionable and improbable. Loans classified as “loss” are considered uncollectible so that their continuance as assets without the establishment of a specific loss allowance is not warranted.

Credit relationships that have been classified as substandard or doubtful and are greater than or equal to $1.0 million are reviewed by the Credit Administration department for possible impairment. A loan is considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement, including both contractual principal and interest payments.

If such an individual loan is deemed to be impaired, the Credit Administration department determines the proper measure of impairment for each loan based on one of three methods: (1) the present value of expected future cash flows discounted at the loan’s effective interest rate; (2) the loan’s observable market price; or (3) the fair value of the collateral if the loan is collateral dependent, less costs of sale or disposal. If the measurement of the impaired loan is more or less than the recorded investment in the loan, the Credit Administration department adjusts the specific allowance associated with that individual loan accordingly.

If a substandard or doubtful loan is not considered individually for impairment, it is grouped with other loans that possess common characteristics for impairment evaluation and analysis. This segmentation is accomplished by grouping loans of similar product types, risk characteristics and industry concentration into homogeneous pools. Historical loss ratios are analyzed and adjusted based on delinquency trends as well as the current economic, political, regulatory, and interest rate environment and used to estimate the current measure of impairment.

The individual impairment measures along with the estimated loss for each homogeneous pool are consolidated into one summary document. This summary schedule along with the support documentation used to establish this schedule is presented to management’s Allowance for Loan Loss Committee ("ALL Committee") monthly. The ALL Committee reviews and approves the processes and ALL documentation presented. Based on this review and discussion, the appropriate amount of ALL is estimated and any adjustments to reconcile the actual ALL with this estimate are determined. The ALL Committee also considers if any changes to the methodology are needed. In addition to the ALL Committee's review and approval, a review is performed by the Risk Management Committee of the Board of Directors on a quarterly basis and annually by internal audit.

Table of Contents

In addition to the reviews by management’s ALL Committee and the Board of Directors’ Risk Management Committee, regulators from either the FDIC and/or the Pennsylvania Department of Banking and Securities perform an extensive review on at least an annual basis for the adequacy of the ALL and its conformity with regulatory guidelines and pronouncements. Any recommendations or enhancements from these independent parties are considered by management and the ALL Committee and implemented accordingly.

We acknowledge that this is a dynamic process and consists of factors, many of which are external and out of our control that can change frequently, rapidly and substantially. The adequacy of the ALL is based upon estimates using all the information previously discussed as well as current and known circumstances and events. There is no assurance that actual portfolio losses will not be substantially different than those that were estimated.

We utilize a structured methodology each period when analyzing the adequacy of the allowance for loan losses and the related provision for loan losses, which the ALL Committee assesses regularly for appropriateness. As part of the analysis as of September 30, 2019, we considered the economic conditions in our markets, such as unemployment and bankruptcy levels as well as changes in estimates of real estate collateral values, and no material changes in methodology were determined to be necessary. In addition, we considered the overall trends in asset quality, specific reserves needed and/or already established for criticized loans, historical loss rates and collateral valuations. The ALL decreased by $2.4 million, or 4.3%, to $52.9 million, or 0.60% of total loans at September 30, 2019 from $55.2 million, or 0.69% of total loans, at December 31, 2018. This decrease is due primarily to the write down of $4.0 million on a residential land development loan in our Western New York region which was previously fully reserved. Partially offsetting this decrease was an increase in substandard loans of $21.8 million, or 11.9%, slightly offset by the decrease in loans classified as special mention of $6.9 million, or 6.1%. Loans classified as substandard increased to $205.6 million at September 30, 2019 from $183.8 million at December 31, 2018. Loans classified as special mention decreased to $107.0 million at September 30, 2019 from $114.0 million at December 31, 2018.

We also consider how the levels of non-accrual loans and historical charge-offs have influenced the required amount of allowance for loan losses. Nonaccrual loans of $65.7 million, or 0.74% of total loans receivable at September 30, 2019, decreased by $6.624 million, or 9.2%, from $72.3 million, or 0.90% of total loans receivable, at December 31, 2018. As a percentage of average loans, annualized net charge-offs increased to 0.26% for the nine months ended September 30, 2019 compared to 0.28% for the year ended December 31, 2018.

Comparison of Operating Results for the Quarters Ended September 30, 2019 and 2018

Net income for the quarter ended September 30, 2019 was $33.4 million, or $0.31 per diluted share, an increase of $5.7 million, or 20.5%, from net income of $27.7 million, or $0.27 per diluted share, for the quarter ended September 30, 2018. The increase in net income resulted from an increase in net interest income of $5.1 million, or 6.0%, a decrease in the provision for loan losses of $3.7 million or 52.7% and an increase in noninterest income of $3.6 million, or 16.0%. Partially offsetting these improvements was an increase in noninterest expense of $4.0 million, or 6.0% and an increase in income tax expense of $2.8 million, or 39.2%. Net income for the quarter ended September 30, 2019 represents annualized returns on average equity and average assets of 9.90% and 1.25%, respectively, compared to 8.93% and 1.15% for the same quarter last year. A further discussion of notable changes follows.

Interest Income

Total interest income increased by $11.3 million, or 11.8%, to $106.9 million for the quarter ended September 30, 2019 from $95.6 million for the quarter ended September 30, 2018. This increase is attributed to increases in both the average balance and average yield on interest earning assets. The average yield earned on interest earning assets increased to 4.39% for the quarter ended September 30, 2019 from 4.31% for the quarter ended September 30, 2018 due to increases in market interest rates over the past year before the Federal Reserve started its recent interest rate easing strategy. Additionally, the average balance of interest earning assets increased by $845.3 million, or 9.6%, to $9.651 billion for the quarter ended September 30, 2019 from $8.806 billion for the quarter ended September 30, 2018 due primarily to internal loan growth as well as the acquisition of UCB.

Interest income on loans receivable increased by $10.4 million, or 11.4%, to $101.1 million for the quarter ended September 30, 2019 from $90.7 million for the quarter ended September 30, 2018. This increase is attributed to increases in both the average balance and average yield on loans receivable. The average balance increased by $819.2 million, or 10.3%, to $8.747 billion for the quarter ended September 30, 2019 from $7.927 billion for the quarter ended September 30, 2018. This increase is due to organic loan growth of $451.2 million during the last twelve months as well as loans acquired of $407.8 million from UCB. Additionally, the average yield on loans receivable increased to 4.59% for the quarter ended September 30, 2019 from 4.54% for the quarter ended September 30, 2018 primarily as a result of the increases in market interest rates last year.

Interest income on mortgage-backed securities increased by $616,000, or 17.2%, to $4.2 million for the quarter ended September 30, 2019 from $3.6 million for the quarter ended September 30, 2018. This increase is attributed to increases in both the average balance and the average yield on mortgage-backed securities. The average yield on mortgage-backed securities increased to 2.61% for the quarter ended September 30, 2019 from 2.39% for the quarter ended September 30, 2018 due to the purchase of fixed-rate

Table of Contents

mortgage-backed securities, including the UCB portfolio, with yields higher than the existing Northwest portfolio. The average balance of mortgage-backed securities increased by $42.5 million, or 7.1%, to $641.1 million for the quarter ended September 30, 2019 from $598.6 million for the quarter ended September 30, 2018 primarily as a result of investment securities received as part of the UCB acquisition.

Interest income on investment securities increased by $89,000, or 8.7%, to $1.1 million for the quarter ended September 30, 2019 from $1.0 million for the quarter ended September 30, 2018. This increase is attributed to an increase in the average yield on investment securities which increased to 2.03% for the quarter ended September 30, 2019 from 1.67% for the quarter ended September 30, 2018 due to the addition of higher yielding investments, including municipal bonds, from the UCB acquisition. Partially offsetting this increase was a decrease in the average balance of investment securities of $25.6 million, or 10.5% to $218.8 million for the quarter ended September 30, 2019 from $244.3 million for the quarter ended September 30, 2018. This decrease is due primarily to the maturity or call of government agency securities.

Dividends on FHLB stock increased by $188,000, or 158.0%, to $307,000 for the quarter ended September 30, 2019 from $119,000 for the quarter ended September 30, 2018. This increase is attributable to increases in both the average balance and average yield on FHLB stock. The average yield increased to 7.47% for the quarter ended September 30, 2019 from 4.81% for the quarter ended September 30, 2018, as the FHLB of Pittsburgh recently increased yields on required stock purchases for active members. Additionally, the average balance increased by $6.5 million, or 66.0%, to $16.3 million for the quarter ended September 30, 2019 from $9.8 million for the quarter ended September 30, 2018. Required FHLB stock holdings fluctuate with, among other things, the utilization of our borrowing capacity as well as capital requirements established by the FHLB.

Interest income on interest-earning deposits remained relatively flat, increasing by just $10,000, or 6.2%, to $172,000 for the quarter ended September 30, 2019 from $162,000 for the quarter ended September 30, 2018. The average balance of interest-earning deposits increased by $2.8 million, or 10.6%, to $28.8 million for the quarter ended September 30, 2019 from $26.1 million for the quarter ended September 30, 2018, which was offset by the decrease in the average yield on interest-earning deposits to 2.33% for the quarter ended September 30, 2019 from 2.43% for the quarter ended September 30, 2018 as the Federal Reserve recently started decreasing their targeted federal funds rate.

Interest Expense

Interest expense increased by $6.1 million, or 62.8%, to $15.9 million for the quarter ended September 30, 2019 from $9.8 million for the quarter ended September 30, 2018. This increase in interest expense was primarily due to an increase in the average cost of interest-bearing liabilities, which increased to 0.89% for the quarter ended September 30, 2019 from 0.60% for the quarter ended September 30, 2018. This increase resulted from increases in the interest rate paid on deposits and borrowed funds in response to increases in market interest rates last year. In addition, the average balance of interest-bearing liabilities increased by $633.5 million, or 9.8%, to $7.097 billion for the quarter ended September 30, 2019 from $6.464 billion for the quarter ended September 30, 2018. This increase was primarily due to the UCB acquisition which included $479.4 million in deposits.

Net Interest Income

Net interest income increased by $5.1 million, or 6.0%, to $90.9 million for the quarter ended September 30, 2019 from $85.8 million for the quarter ended September 30, 2018. This increase is attributable to the factors discussed above. Our interest bearing deposit costs rose greater than yields on interest earning assets reducing our interest rate spread and, as a result of the inverted yield curve, we are experiencing net interest margin compression. Our interest rate spread decreased to 3.50% for the quarter ended September 30, 2019 from 3.71% for the quarter ended September 30, 2018 and our net interest margin decreased to 3.77% for the quarter ended September 30, 2019 from 3.90% for the quarter ended September 30, 2018.

Provision for Loan Losses

The provision for loan losses decreased by $3.7 million, or 52.7%, to $3.3 million for the quarter ended September 30, 2019 from $7.0 million for the quarter ended September 30, 2018. The provision was elevated in the prior year due primarily to a $4.6 million write-down of a land development loan in the third quarter of 2018. In addition, total loan delinquency decreased by $12.5 million to $81.0 million, or 0.9% of total loans, at September 30, 2019 from $93.6 million, or 1.2% of total loans at September 30, 2018. Annualized net charge-offs to average loans decreased to 0.16% for the quarter ended September 30, 2019 from 0.42% for the quarter ended September 30, 2018 due primarily to the land development write-down noted above.

Table of Contents

In determining the amount of the current period provision, we considered current economic conditions, including but not limited to unemployment levels, bankruptcy filings, and changes in real estate values and the impact of these factors on the quality of our loan portfolio and historical loss experience. We analyze the allowance for loan losses as described in the section entitled “Allowance for Loan Losses.” The provision that is recorded is sufficient, in our judgment, to bring this reserve to a level that reflects the losses inherent in our loan portfolio relative to loan mix, economic conditions and historical loss experience at September 30, 2019.

Noninterest Income

Noninterest income increased by $3.6 million, or 16.0%, to $26.2 million for the quarter ended September 30, 2019 from $22.6 million for the quarter ended September 30, 2018. This increase was primarily due to a $1.8 million increase in mortgage banking income as a result of expanding our secondary market sales capabilities. In addition, there was a $696,000 increase in other operating income from increases in interest rate swap fees and Visa dividend income, a $400,000 increase in service charges and fees as a result of increased customer activity from the UCB acquisition, and a $355,000 increase in trust and other financial services income due to new brokerage production. In addition, we recognized a gain of $826,000 in the current quarter on the sale of $46.0 million of one-to-four family mortgage loans from our portfolio. We chose to sell these loans as they were identified as most likely to refinance due to declining interest rates and redeploy those proceeds into shorter duration loans at an equivalent yield.

Noninterest Expense

Noninterest expense increased by $4.0 million, or 6.0%, to $70.6 million for the quarter ended September 30, 2019 from $66.6 million for the quarter ended September 30, 2018. This increase resulted primarily from a $3.3 million, or 8.7%, increase in compensation and employee benefits due to both internal growth in compensation and staff as well as the addition of UCB employees. In addition, processing expenses increased by $1.5 million, or 15.6%, as we continue to invest in technology and infrastructure and refresh our loan origination platforms. Partially offsetting this increase was a decrease in federal deposit insurance premiums of $1.4 million due to an assessment credit received during the quarter as a result of the deposit insurance fund becoming fully funded.

Income Taxes

The provision for income taxes increased by $2.8 million, or 39.2%, to $9.8 million for the quarter ended September 30, 2019 from $7.0 million for the quarter ended September 30, 2018. In addition to the increase in income before tax of $8.4 million, or 24.2%, our effective tax rate for the quarter ended September 30, 2019 was 22.7% compared to 20.2% for the quarter ended September 30, 2018. We anticipate our effective tax rate to be between 21.0% and 23.0% for the year ending December 31, 2019.

Comparison of Operating Results for the Nine Months Ended September 30, 2019 and 2018

Net income for the nine months ended September 30, 2019 was $84.8 million, or $0.80 per diluted share, an increase of $5.8 million, or 7.4%, from $79.0 million, or $0.76 per diluted share, for the nine months ended September 30, 2018. The increase in net income resulted from an increase in interest income of $35.9 million, or 12.9%, and an increase in noninterest income of $2.7 million, or 4.0%. Partially offsetting this improvement were increases in interest expense of $16.2 million, or 62.0%, and noninterest expense of $15.7 million, or 7.7%. Net income for the nine months ended September 30, 2019 represents annualized returns on average equity and average assets of 8.65% and 1.10%, respectively, compared to 8.67% and 1.11% for the nine months ended September 30, 2018. A discussion of significant changes follows.

Interest Income

Total interest income increased by $35.9 million, or 12.9%, to $314.0 million for the nine months ended September 30, 2019 from $278.0 million for the nine months ended September 30, 2018. This increase is the result of increases in both the average balance and average yield earned on interest earning assets. The average yield earned on interest earning assets increased to 4.47% for the nine months ended September 30, 2019 from 4.26% for the nine months ended September 30, 2018. This increase in average yield is attributed to increases in market interest rates over the past year. Additionally, the average balance of interest earning assets increased by $656.2 million, or 7.5%, to $9.391 billion for the nine months ended September 30, 2019 from $8.735 billion for the nine months ended September 30, 2018 due primarily to internal loan growth as well as the UCB acquisition.

Interest income on loans receivable increased by $32.9 million, or 12.5%, to $296.9 million for the nine months ended September 30, 2019 from $264.1 million for the nine months ended September 30, 2018. This increase is attributed to increases in both the average balance and average yield on loans receivable. The average balance increased by $649.8 million, or 8.3%, to $8.501 billion for the nine months ended September 30, 2019 from $7.851 billion for the nine months ended September 30, 2018. This increase is due to organic loan growth of $451.2 million during the last twelve months as well as loans of $407.8 million from the UCB acquisition. Additionally, the average yield on loans receivable increased to 4.67% for the nine months ended September 30, 2019 from 4.50% for the nine months ended September 30, 2018, primarily as a result of the increases in market interest rates over the past year.

Interest income on mortgage-backed securities increased by $2.6 million, or 26.4%, to $12.4 million for the nine months ended September 30, 2019 from $9.8 million for the nine months ended September 30, 2018. This increase is attributed to increases in both the average balance and average yield on mortgage-backed securities. The average balance of mortgage-backed securities increased by $54.6 million, or 9.5%, to $630.3 million for the nine months ended September 30, 2019 from $575.7 million for the nine months ended September 30, 2018. This increase is due primarily to the addition of the UCB portfolio. Additionally, the average yield on mortgage-backed securities increased to 2.63% for the nine months ended September 30, 2019 from 2.28% for the nine months ended September 30, 2018, due to both an increase in short-term market interest rates that positively impacted our adjustable rate mortgage-backed securities and the purchase of fixed-rate mortgage-backed securities with yields higher than the existing portfolio.

Interest income on investment securities increased by $313,000, or 10.3%, to $3.4 million for the nine months ended September 30, 2019 from $3.0 million for the nine months ended September 30, 2018. This increase is primarily attributable to an increase in the average yield on investment securities to 2.00% for the nine months ended September 30, 2019 from 1.66% for the nine months ended September 30, 2018. The increase in yield is due to the addition of higher yielding investments from the UCB acquisition. Partially offsetting this increase was a decrease in the average balance of investment securities of $21.3 million, or 8.7%, to $224.1 million for the nine months ended September 30, 2019 from $245.4 million for the nine months ended September 30, 2018. This decrease is due primarily to the maturity or call of government agency securities.

Dividends on FHLB stock increased by $493,000, or 163.8%, to $794,000 for the nine months ended September 30, 2019 from $301,000 for the nine months ended September 30, 2018. This increase is attributable to increases in both the average balance and average yield on FHLB stock. The average yield increased to 7.15% for the nine months ended September 30, 2019 from 4.47% for the nine months ended September 30, 2018, and the average balance increased by $5.8 million, or 64.9%, to $14.8 million for the nine months ended September 30, 2019 from $9.0 million for the nine months ended September 30, 2018. Required FHLB stock holdings fluctuate with, among other things, the utilization of our borrowing capacity as well as capital requirements established by the FHLB and dividend yields.

Interest income on interest-earning deposits decreased by $335,000, or 43.7%, to $431,000 for the nine months ended September 30, 2019 from $766,000 for the nine months ended September 30, 2018. This decrease is attributable to a decrease in the average balance of interest-earning deposits, which decreased by $32.7 million, or 61.4%, to $20.5 million for the nine months ended September 30, 2019 from $53.3 million for the nine months ended September 30, 2018, due to the utilization of excess cash to fund loan growth. Partially offsetting this decrease was an increase in the average yield on interest-earning deposits to 2.77% for the nine months ended September 30, 2019 from 1.90% for the nine months ended September 30, 2018, as a result of increases in the targeted Federal Funds rate by the Federal Reserve last year.

Interest Expense

Interest expense increased by $16.2 million, or 62.0%, to $42.4 million for the nine months ended September 30, 2019 from $26.2 million for the nine months ended September 30, 2018. This increase in interest expense was due to an increase in the average cost of interest-bearing liabilities to 0.82% for the nine months ended September 30, 2019 from 0.54% for the nine months ended September 30, 2018. This increase resulted from increases in the interest rate paid on deposits and borrowed funds in response to increases in market interest rates. In addition, the average balance of interest-bearing liabilities increased by $431.9 million, or 6.7%, to $6.910 billion for the nine months ended September 30, 2019 from $6.478 billion for the nine months ended September 30, 2018. This increase was primarily due to the UCB acquisition, which included $479.4 million in deposits, as well as internal growth of funding sources.

Net Interest Income

Net interest income increased by $19.7 million, or 7.8%, to $271.5 million for the nine months ended September 30, 2019 from $251.8 million for the nine months ended September 30, 2018. This increase is attributable to the factors discussed above. Our interest rate spread decreased to 3.65% for the nine months ended September 30, 2019 from 3.71% for the nine months ended September 30, 2018 and our net interest margin increased slightly to 3.86% for the nine months ended September 30, 2019 from 3.84% for the nine months ended September 30, 2018.

Provision for Loan Losses

The provision for loan losses decreased by $2.1 million, or 12.7%, to $14.4 million for the nine months ended September 30, 2019 from $16.5 million for the nine months ended September 30, 2018. Total nonaccrual loans decreased by $8.6 million to $65.7 million, or 0.74% of total loans, at September 30, 2019 from $74.2 million, or 0.93% of total loans at September 30, 2018. Annualized net charge-offs to average loans decreased to 0.26% for the nine months ended September 30, 2019 from 0.29% for the nine months ended September 30, 2018.

Noninterest Income

Noninterest income increased by $2.7 million, or 4.0%, to $71.2 million for the nine months ended September 30, 2019 from $68.5 million for the nine months ended September 30, 2018. This increase was primarily due to a $1.9 million increase in mortgage banking income as a result of expanding our secondary market sales capabilities. Additionally, service charges and fees increased by $1.0 million, or 2.6%, as a result of increased customer activity from the UCB acquisition and trust and other financial services income increased by $913,000, or 7.4%, due to new brokerage production. Offsetting this increase was a decrease in bank owned life insurance income of $1.5 million, or 31.1%, due to a death benefit received during the prior year.

Noninterest Expense

Noninterest expense increased by $15.7 million, or 7.7%, to $219.5 million for the nine months ended September 30, 2019, from $203.8 million for the nine months ended September 30, 2018. This increase resulted primarily from a $7.9 million, or 7.0%, increase in compensation and employee benefits due to both internal growth in compensation and staff as well as the addition of UCB employees. Also contributing to this increase was an increase in processing expense by $3.3 million, or 11.4%, as we continue to invest in technology and infrastructure, an increase in restructuring and acquisition expense of $2.5 million due to expenses incurred as part of the UCB acquisition, an increase in other expenses of $1.4 million, or 19.3%, primarily due to an increase in pension related servicing costs, and an increase in professional services of $1.3 million, or 17.3% due primarily to he engagement of deposit strategy consultants. Partially offsetting this increase was a decrease in federal deposit insurance premiums of $1.4 million due to an assessment credit received during the quarter as a result of the deposit insurance fund becoming fully funded.

Income Taxes

The provision for income taxes increased by $3.0 million, or 14.5%, to $23.9 million for the nine months ended September 30, 2019 from $20.9 million for the nine months ended September 30, 2018. In addition to the increase in income before tax of $8.8 million, or 8.9%, our effective tax rate for the nine months ended September 30, 2019 was 22.0% compared to 20.9% for the nine months ended September 30, 2018. We anticipate our effective tax rate to be between 21.0% and 23.0% for the year ending December 31, 2019.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As the holding company for a savings bank, one of our primary market risks is interest rate risk. Interest rate risk is the sensitivity of net interest income to variations in interest rates over a specified time period. The sensitivity results from differences in the time periods in which interest rate sensitive assets and liabilities mature or re-price. We attempt to control interest rate risk by matching, within acceptable limits, the re-pricing periods of assets and liabilities. We have attempted to limit our exposure to interest sensitivity by increasing core deposits, enticing customers to extend certificates of deposit maturities, borrowing funds with fixed-rates and longer maturities and by shortening the maturities of our assets by emphasizing the origination of more short-term fixed rate loans and adjustable rate loans. We also have the ability to sell a portion of the long-term, fixed-rate mortgage loans that we originate. In addition, we purchase shorter term or adjustable-rate investment securities and mortgage-backed securities.

We have an Asset/Liability Committee consisting of members of management which meets monthly to review market interest rates, economic conditions, the pricing of interest-earning assets and interest-bearing liabilities and the balance sheet structure. On a quarterly basis, this Committee also reviews the interest rate risk position and cash flow projections.

The Board of Directors has a Risk Management Committee which meets quarterly and reviews interest rate risk and trends, our interest sensitivity position, the liquidity position and the market risk inherent in the investment portfolio.

In an effort to assess interest rate risk and market risk, we utilize a simulation model to determine the effect of immediate incremental increases and decreases in interest rates on net income and the market value of equity. Certain assumptions are made regarding loan prepayments and decay rates of savings and interest-bearing demand accounts. Because it is difficult to accurately project the market reaction of depositors and borrowers, the effect of actual changes in interest rates on these assumptions may differ from simulated results. We have established the following guidelines for assessing interest rate risk:

Net interest income simulation. Given a parallel shift of 100 basis points (“bps”), 200 bps and 300 bps in interest rates, the estimated net income may not decrease by more than 5%, 10% and 15%, respectively, within a one-year period.

Net income simulation. Given a parallel shift of 100 bps, 200 bps and 300 bps in interest rates, the estimated net income may not decrease by more than 10%, 20% and 30%, respectively, within a one-year period.

Market value of equity simulation. The market value of equity is the present value of assets and liabilities. Given a parallel shift of 100 bps, 200 bps and 300 bps in interest rates, the market value of equity may not decrease by more than 15%, 30% and 35%, respectively, from the computed economic value at current interest rate levels.

The following table illustrates the simulated impact of a 100 bps, 200 bps or 300 bps upward or a 100 bps downward movement in interest rates on net income, return on average equity, earnings per share and market value of equity. This analysis was prepared assuming that interest-earning asset and interest-bearing liability levels at September 30, 2019 remain constant. The impact of the rate movements was computed by simulating the effect of an immediate and sustained shift in interest rates over a twelve-month period from September 30, 2019 levels.



	Increase									Decrease
Parallel shift in interest rates over the next 12 months	100 bps			200 bps			300 bps			100 bps
Projected percentage increase/(decrease) in net interest income	(1.6		)%	(2.7		)%	(4.2		)%	(4.9		)%
Projected percentage increase/(decrease) in net income	(3.6		)%	(6.2		)%	(9.7		)%	(12.0		)%
Projected increase/(decrease) in return on average equity	(3.6		)%	(6.0		)%	(9.4		)%	(11.7		)%
Projected increase/(decrease) in earnings per share	$	0.04		$	(0.07	)	$	(0.10	)	$	(0.13	)
Projected percentage increase/(decrease) in market value of equity	(3.0		)%	(5.8		)%	(9.2		)%	(3.4		)%

The figures included in the table above represent projections that were computed based upon certain assumptions including prepayment rates and decay rates. These assumptions are inherently uncertain and, as a result, cannot precisely predict the impact of changes in interest rates. Actual results may differ significantly due to timing, magnitude and frequency of interest rate changes and changes in market conditions, and actions that may be taken by management in response to interest rate changes.

Item 4. CONTROLS AND PROCEDURES

Under the supervision of and with the participation of management, including the Principal Executive Officer and Principal Financial Officer, we evaluated the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this quarterly report (the “Evaluation Date”). Based upon that evaluation, the Principal Executive Officer and Principal Financial Officer concluded that, as of the Evaluation Date, these disclosure controls and procedures were effective.

There were no changes in the internal controls over financial reporting during the period covered by this report or in other factors that have materially affected, or are reasonably likely to materially affect the internal controls over financial reporting.

PART II. OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

We are subject to a number of asserted and unasserted claims encountered in the normal course of business. We believe that any additional liability, other than that which has already been accrued, that may result from such potential litigation will not have a material adverse effect on the financial statements. However, we cannot presently determine whether or not any claims against us will have a material adverse effect on our results of operations in any future reporting period. Refer to note 13.

Item 1A. RISK FACTORS

Except as previously disclosed, there have been no material updated or additions to the risk factors previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 as filed with the Securities and Exchange Commission. Additional risks not presently known to us, or that we currently deem immaterial, may also adversely affect our business, financial condition or results of operations.
