COMMUNITY BANK SYSTEM, INC.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
SEPTEMBER 30, 2017
NOTE A: BASIS OF PRESENTATION
The interim financial data as of and for the three and nine months ended September 30, 2017 is unaudited; however, in the opinion of Community Bank System, Inc. (the “Company”), the interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results for the interim periods in conformity with generally accepted accounting principles (“GAAP”). The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.
NOTE B: ACQUISITIONS
On May 12, 2017, the Company completed its acquisition of Merchants Bancshares, Inc. (“Merchants”), parent company of Merchants Bank headquartered in South Burlington, Vermont, for $345.2 million in Company stock and cash, comprised of $82.9 million in cash and the issuance of 4.68 million shares of common stock. The acquisition extends the Company’s footprint into the Vermont and Western Massachusetts markets with the addition of 31 branch locations in Vermont and one location in Massachusetts. This transaction resulted in the acquisition of $1.99 billion of assets, including $1.49 billion of loans and $370.6 million of investment securities, as well as $1.45 billion of deposits and $188.3 million in goodwill. The effects of the acquired assets and liabilities have been included in the consolidated financial statements since that date. Revenues of approximately $16.8 million and direct expenses, which may not include certain shared expenses, of approximately $7.5 million from Merchants were included in the consolidated income statement for the three months ended September 30, 2017. Revenues of approximately $25.8 million and direct expenses, which may not include certain shared expenses, of approximately $11.5 million from Merchants were included in the consolidated income statement for the nine months ended September 30, 2017.
On March 1, 2017, the Company, through its subsidiary, OneGroup NY, Inc. (“OneGroup”), completed its acquisition of certain assets of Dryfoos Insurance Agency, Inc. (“Dryfoos”), an insurance agency headquartered in Hazleton, Pennsylvania. The Company paid $3.0 million in cash to acquire the assets of Dryfoos, and recorded goodwill in the amount of $1.7 million and other intangible assets of $1.7 million in conjunction with the acquisition. The effects of the acquired assets and liabilities have been included in the consolidated financial statements since that date.
On February 3, 2017, the Company completed its acquisition of Northeast Retirement Services, Inc. (“NRS”) and its subsidiary Global Trust Company, Inc. (“GTC”), headquartered in Woburn, Massachusetts, for $148.6 million in Company stock and cash. NRS was a privately held corporation focused on providing institutional transfer agency, master recordkeeping services, custom target date fund administration, trust product administration and customized reporting services to institutional clients. Its wholly-owned subsidiary, GTC, is chartered in the State of Maine as a non-depository trust company and provides fiduciary services for collective investment trusts and other products. The acquisition of NRS and GTC, hereafter referred to collectively as NRS, will strengthen and complement the Company’s existing employee benefit services businesses. Upon the completion of the merger, NRS became a wholly-owned subsidiary of Benefit Plans Administrative Services, Inc. (“BPAS”) and operates as Northeast Retirement Services, LLC, a Delaware limited liability company. This transaction resulted in the acquisition of $36.1 million in net tangible assets, principally cash and certificates of deposit, $60.2 million in customer list intangibles that will be amortized using the 150% declining balance method over 10 years, a $24.2 million deferred tax liability associated with the customer list intangible, and $76.5 million in goodwill. The effects of the acquired assets and liabilities have been included in the consolidated financial statements since that date. Revenues of $8.7 million and expenses of $5.8 million from NRS were included in the consolidated income statement for the three months ended September 30, 2017. Revenues of $22.1 million and expenses of $15.1 million from NRS were included in the consolidated income statement for the nine months ended September 30, 2017.

The assets and liabilities assumed in the acquisitions were recorded at their estimated fair values based on management's best estimates using information available at the dates of the acquisition, and were subject to adjustment based on updated information not available at the time of acquisition. During the second quarter of 2017, the carrying amount of other assets decreased by $2.7 million and other liabilities decreased by $2.4 million as a result of a reclassification of amounts from other assets into other liabilities, and an adjustment to other liabilities as a result of updated information not available at the time of acquisition. Goodwill associated with the NRS acquisition increased $0.3 million during the second quarter as a result of these changes in fair value. During the third quarter of 2017, the carrying amount of investments increased by $0.2 million as a result of updated information not available at the time of acquisition, the carrying amount of loans decreased $0.6 million as a result of an adjustment to the valuation of acquired impaired loans, the carrying amount of premises and equipment increased $3.6 million as a result of updated appraisal information not available at the time of acquisition, and the value of other assets and other liabilities increased $5.5 million and $6.6 million, respectively, as a result of adjustments to accrued income taxes, deferred taxes and certain tax credit arrangements that were recorded on a provisional basis. Goodwill associated with the NRS and Merchants acquisitions decreased $0.1 million and $2.0 million, respectively, as a result of these changes in fair value estimates.
The above referenced acquisitions expanded the Company’s geographical presence in New York, Pennsylvania, Vermont, and Western Massachusetts and management expects that the Company will benefit from greater geographic diversity and the advantages of other synergistic business development opportunities.
The following table summarizes the estimated fair value of the assets acquired and liabilities assumed after considering the measurement period adjustments described above:

(1) Includes amounts related to the BAS and Dryfoos acquisitions.
Acquired loans that have evidence of deterioration in credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments were aggregated by comparable characteristics and recorded at fair value without a carryover of the related allowance for loan losses. Cash flows for each loan were determined using an estimate of credit losses and rate of prepayments. Projected monthly cash flows were then discounted to present value using a market-based discount rate. The excess of the undiscounted expected cash flows over the estimated fair value is referred to as the “accretable yield” and is recognized into interest income over the remaining lives of the acquired loans.

Fair value of acquired loans |  | $ | 9,799 |  |  | $ | 1,478,881 |  |  | $ | 1,488,680 |

The fair value of checking, savings and money market deposit accounts acquired were assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. Certificate of deposit accounts were valued at the present value of the certificates’ expected contractual payments discounted at market rates for similar certificates.
The core deposit intangibles and other intangibles related to the Merchants, Dryfoos, BAS and WJL acquisitions are being amortized using an accelerated method over their estimated useful life of eight years. The goodwill, which is not amortized for book purposes, was assigned to the Banking segment for the Merchants acquisition, the Employee Benefit Services segment for NRS, and All Other segments for the Dryfoos, BAS, and WJL acquisitions. Goodwill arising from the Merchants and NRS acquisitions is not deductible for tax purposes. Goodwill arising from the Dryfoos, BAS and WJL acquisitions is deductible for tax purposes.
Direct costs related to the acquisitions were expensed as incurred. Merger and acquisition integration-related expenses amount to $0.6 million during the three months ended September 30, 2017, and $25.2 million and $0.3 million for the nine months ended September 30, 2017 and 2016, respectively, and have been separately stated in the Consolidated Statements of Income. Merger and acquisition integration-related expenses for the three months ended September 30, 2016 were immaterial.
Supplemental Pro Forma Financial Information
The following unaudited condensed pro forma information assumes the Merchants and NRS acquisitions had been completed as of January 1, 2016 for the three and nine months ended September 30, 2016 and September 30, 2017. The pro forma information does not include amounts related to BAS and Dryfoos as the amounts were immaterial. The table below has been prepared for comparative purposes only and is not necessarily indicative of the actual results that would have been attained had the acquisitions occurred as of the beginning of the year presented, nor is it indicative of the Company’s future results. Furthermore, the unaudited pro forma information does not reflect management’s estimate of any revenue-enhancing opportunities nor anticipated cost savings that may have occurred as a result of the integration and consolidation of the acquisitions.
The pro forma information set forth below reflects the historical results of Merchants and NRS combined with the Company’s consolidated statement of income with adjustments related to (a) certain purchase accounting fair value adjustments and (b) amortization of customer lists and core deposit intangibles. Acquisition expenses related to the Merchants and NRS transactions totaling $0.5 million and $25.0 million for the three and nine months ended September 30, 2017 were included in the pro forma information as if they were incurred in the first quarter of 2016.

Table of Contents
NOTE C: ACCOUNTING POLICIES
The accounting policies of the Company, as applied in the consolidated interim financial statements presented herein, are substantially the same as those followed on an annual basis as presented on pages 59 through 65 of the Annual Report on Form 10-K for the year ended December 31, 2016 filed with the Securities and Exchange Commission (“SEC”) on March 1, 2017.
Critical Accounting Policies
Acquired Loans
Acquired loans are initially recorded at their acquisition date fair values. The carryover of allowance for loan losses is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for acquired loans are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values and discount rate.
Acquired Impaired Loans
Acquired loans that have evidence of deterioration in credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments are accounted for as impaired loans under Accounting Standards Codification (“ASC”) 310-30. The excess of undiscounted cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loans using the interest method. The difference between contractually required payments at acquisition and the undiscounted cash flows expected to be collected at acquisition is referred to as the non-accretable discount. The non-accretable discount represents estimated future credit losses and other contractually required payments that the Company does not expect to collect. Subsequent decreases in expected cash flows are recognized as impairments through a charge to the provision for loan losses resulting in an increase in the allowance for loan losses. Subsequent improvements in expected cash flows result in a recovery of previously recorded allowance for loan losses or a reversal of a corresponding amount of the non-accretable discount, which the Company then reclassifies as an accretable discount that is recognized into interest income over the remaining life of the loans using the interest method.
Acquired loans that met the criteria for non-accrual of interest prior to acquisition may be considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if the Company can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, the Company may no longer consider the loans to be non-accrual or non-performing and may accrue interest on these loans, including the impact of any accretable discount.
Acquired Non-impaired Loans
Acquired loans that do not meet the requirements under ASC 310-30 are considered acquired non-impaired loans. The difference between the acquisition date fair value and the outstanding balance represents the fair value adjustment for a loan and includes both credit and interest rate considerations. Fair value adjustments may be discounts (or premiums) to a loan’s cost basis and are accreted (or amortized) to net interest income (or expense) over the loan’s remaining life in accordance with ASC 310-20. Fair value adjustments for revolving loans are accreted (or amortized) using a straight line method. Term loans are accreted (or amortized) using the constant effective yield method.
Subsequent to the purchase date, the methods used to estimate the allowance for loan losses for the acquired non-impaired loans are consistent with the policy described below. However, the Company compares the net realizable value of the loans to the carrying value, for loans collectively evaluated for impairment. The carrying value represents the net of the loan’s unpaid principal balance and the remaining purchase discount (or premium) that has yet to be accreted into interest income. When the carrying value exceeds the net realizable value, an allowance for loan loss is recognized.
Allowance for Loan Losses
Management continually evaluates the credit quality of the Company’s loan portfolio, and performs a formal review of the adequacy of the allowance for loan losses on a quarterly basis. The allowance reflects management’s best estimate of probable losses inherent in the loan portfolio. Determination of the allowance is subjective in nature and requires significant estimates. The Company’s allowance methodology consists of two broad components - general and specific loan loss allocations.
11

Table of Contents
The general loan loss allocation is composed of two calculations that are computed on five main loan segments: business lending; consumer direct; consumer indirect; home equity; and consumer mortgage. The first calculation is quantitative and determines an allowance level based on the latest 36 months of historical net charge-off data for each loan class (commercial loans exclude balances with specific loan loss allocations). The second calculation is qualitative and takes into consideration eight qualitative environmental factors: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards, and other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. A component of the qualitative calculation is the unallocated allowance for loan loss. The qualitative and quantitative calculations are added together to determine the general loan loss allocation. The specific loan loss allocation relates to individual commercial loans that are both greater than $0.5 million and in a nonaccruing status with respect to interest. Specific loan losses are based on discounted estimated cash flows, including any cash flows resulting from the conversion of collateral or collateral shortfalls. The allowance levels computed from the specific and general loan loss allocation methods are combined with unallocated allowances and allowances needed for acquired loans to derive the total required allowance for loan losses to be reflected on the Consolidated Statement of Condition.
Loan losses are charged off against the allowance, while recoveries of amounts previously charged off are credited to the allowance. A provision for loan losses is charged to operations based on management’s periodic evaluation of factors previously mentioned.
Investment Securities
The Company can classify its investments in debt and equity securities as held-to-maturity, available-for-sale, or trading. Held-to-maturity securities are those for which the Company has the positive intent and ability to hold until maturity, and are reported at cost, which is adjusted for amortization of premiums and accretion of discounts. Securities classified as available-for-sale are reported at fair value with net unrealized gains and losses reflected as a separate component of shareholders' equity, net of applicable income taxes. None of the Company's investment securities have been classified as trading securities at September 30, 2017. Certain equity securities are stated at cost and include restricted stock of the Federal Reserve Bank of New York (“Federal Reserve”), the Federal Home Loan Bank of New York and the Federal Home Loan Bank of Boston (collectively referred to as “FHLB”).
Fair values for investment securities are based upon quoted market prices, where available. If quoted market prices are not available, fair values are based upon quoted market prices of comparable instruments, or a discounted cash flow model using market estimates of interest rates and volatility.
The Company conducts an assessment of all securities in an unrealized loss position to determine if other-than-temporary impairment (“OTTI”) exists on a quarterly basis. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis. The OTTI assessment considers the security structure, recent security collateral performance metrics, if applicable, external credit ratings, failure of the issuer to make scheduled interest or principal payments, judgment about, and expectations of, future performance, and relevant independent industry research, analysis and forecasts. The severity of the impairment and the length of time the security has been impaired is also considered in the assessment. The assessment of whether an OTTI decline exists is performed on each security, regardless of the classification of the security as available-for-sale or held-to-maturity and involves a high degree of subjectivity and judgment that is based on the information available to management at a point in time.
An OTTI loss must be recognized for a debt security in an unrealized loss position if there is intent to sell the security or it is more likely than not the Company will be required to sell the security prior to recovery of its amortized cost basis. In this situation, the amount of loss recognized in income is equal to the difference between the fair value and the amortized cost basis of the security. Even if management does not have the intent, and it is not more likely than not that the Company will be required to sell the securities, an evaluation of the expected cash flows to be received is performed to determine if a credit loss has occurred. For debt securities, a critical component of the evaluation for OTTI is the identification of credit-impaired securities, where the Company does not expect to receive cash flows sufficient to recover the entire amortized cost basis of the security. In the event of a credit loss, only the amount of impairment associated with the credit loss would be recognized in income. The portion of the unrealized loss relating to other factors, such as liquidity conditions in the market or changes in market interest rates, is recorded in accumulated other comprehensive loss.
Equity securities are also evaluated to determine whether the unrealized loss is expected to be recoverable based on whether evidence exists to support a realizable value equal to or greater than the amortized cost basis. If it is probable that the amortized cost basis will not be recovered, taking into consideration the estimated recovery period and the ability to hold the equity security until recovery, OTTI is recognized in earnings equal to the difference between the fair value and the amortized cost basis of the security.
The specific identification method is used in determining the realized gains and losses on sales of investment securities and OTTI charges. Premiums and discounts on securities are amortized and accreted, respectively, on the interest method basis over the period to maturity or estimated life of the related security. Purchases and sales of securities are recognized on a trade date basis.

Intangible Assets
Intangible assets include core deposit intangibles, customer relationship intangibles and goodwill arising from acquisitions. Core deposit intangibles and customer relationship intangibles are amortized on either an accelerated or straight-line basis over periods ranging from seven to 20 years. The initial and ongoing carrying value of goodwill and other intangible assets is based upon discounted cash flow modeling techniques that require management to make estimates regarding the amount and timing of expected future cash flows. It also requires use of a discount rate that reflects the current return requirements of the market in relation to present risk-free interest rates, required equity market premiums, peer volatility indicators, and company-specific risk indicators.
The Company evaluates goodwill for impairment on an annual basis, or more often if events or circumstances indicate there may be impairment. The implied fair value of a reporting unit’s goodwill is compared to its carrying amount and the impairment loss is measured by the excess of the carrying value over fair value. The fair value of each reporting unit is compared to the carrying amount of such reporting unit in order to determine if impairment is indicated.
Retirement Benefits
The Company provides defined benefit pension benefits to eligible employees and post-retirement health and life insurance benefits to certain eligible retirees. The Company also provides deferred compensation and supplemental executive retirement plans for selected current and former employees, officers, and directors. Expense under these plans is charged to current operations and consists of several components of net periodic benefit cost based on various actuarial assumptions regarding future experience under the plans, including discount rate, rate of future compensation increases, and expected return on plan assets.
Recently Adopted Accounting Pronouncement
In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718). The amendments simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, accounting for award forfeitures, and classification on the statement of cash flows. The amendments were effective for public business entities for the first interim and annual reporting periods beginning after December 15, 2016 and the Company adopted the amendments as of January 1, 2017. The new guidance requires entities to prospectively recognize all excess tax benefits and tax deficiencies related to share-based payment awards as income tax benefit or expense in the statement of income when the awards vest or are settled. Previously, income tax benefits (or deficiencies) were reported as increases (or decreases) to additional paid-in capital to the extent that those benefits were greater than (or less than) the income tax benefits recognized in earnings during the awards’ vesting periods. In addition, excess tax benefits and deficiencies are to be classified as an operating activity in the statement of cash flows, rather than a financing activity as required under prior accounting guidance. The new guidance also requires employee taxes paid when an employer withholds shares for withholding tax purposes to be classified as a financing activity in the statement of cash flows. The Company has elected to apply the changes in presentation on the statement of cash flows for excess tax benefits and deficiencies and employee taxes paid when an employer withholds shares on a retrospective basis. The Company has also elected to continue to incorporate estimated forfeitures in the accrual of compensation expense, and this election had no impact on the Company’s consolidated financial statements. For the three and nine months ended September 30, 2017, the effect on net income from excess tax benefits was $0.3 million, or less than $0.01 per diluted common share, and $2.9 million, or approximately $0.05 per diluted common share, respectively.
New Accounting Pronouncements
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). This new guidance supersedes the revenue recognition requirements in ASC 605, Revenue Recognition, and is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects consideration to which the entity expects to be entitled in exchange for those goods and services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. This guidance is effective for the Company for annual and interim periods beginning after December 15, 2017. The Company will adopt this guidance on January 1, 2018 and anticipates a modified retrospective method of adoption. This method entails recognizing the cumulative effect of applying the new standard, if any, as a change to the opening balance of retained earnings. The Company has developed a project plan for the implementation of this new guidance, including a review of all revenue streams to identify any differences in timing, measurement, or presentation of revenue recognition. The Company is still in the process of determining the impact of the guidance; however, upon initial evaluation, the Company does not anticipate significant changes to its current revenue recognition policy or internal controls over revenue recognition, but changes in classification between noninterest revenues and noninterest expenses could occur.
In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This guidance addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The primary focus of this guidance is to supersede the guidance to classify equity securities with readily determinable fair values into different categories (trading or available-for-sale) and requires equity securities to be measured at fair value with changes in the fair value recognized through net income. This guidance requires adoption through a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted for all companies in any interim or annual period. The Company is currently evaluating the effect the guidance will have on the Company’s consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This new guidance supersedes the lease requirements in Topic 840, Leases and is based on the principle that a lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. The accounting applied by a lessor is largely unchanged from that applied under the previous guidance. In addition, the guidance requires an entity to separate the lease components from the nonlease components in a contract. The ASU requires disclosures about the amount, timing, and judgments related to a reporting entity’s accounting for leases and related cash flows. The standard is required to be applied to all leases in existence as of the date of adoption using a modified retrospective transition approach. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted for all companies in any interim or annual period. The Company occupies certain offices and uses certain equipment under non-cancelable operating lease agreements, which currently are not reflected in its consolidated statement of condition. The Company expects to recognize lease liabilities and right of use assets associated with these lease agreements; however, the extent of the impact on the Company’s consolidated financial statements is currently under evaluation.
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326). This new guidance significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. This ASU will replace the “incurred loss” model under existing guidance with an “expected loss” model for instruments measured at amortized cost, and require entities to record allowances for available-for-sale debt securities rather than reduce the carrying amount, as they do today under the other-than-temporary impairment model. This ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans. This guidance requires adoption through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for all companies as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact the guidance will have on the Company’s consolidated financial statements, and expects a change in the allowance for credit losses resulting from the change to expected losses for the estimated life of the financial asset, including an allowance for debt securities. The amount of the change in the allowance for credit losses resulting from the new guidance will be impacted by the portfolio composition and asset quality at the adoption date, as well as economic conditions and forecasts at the time of adoption.
In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230). The amendments provide guidance on the following eight specific cash flow issues: 1) debt prepayment or debt extinguishment costs; 2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; 3) contingent consideration payments made after a business combination; 4) proceeds from the settlement of insurance claims; 5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; 6) distributions received from equity method investees; 7) beneficial interests in securitization transactions; and 8) separately identifiable cash flows and application of the predominance principle. This ASU is effective for fiscal years beginning after December 31, 2017, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. As this guidance only affects the classification within the statement of cash flows, this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350). The amendments simplify how an entity is required to test goodwill for impairment by eliminating the requirement to measure a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, an entity will perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and recognize an impairment charge for the amount by which the carrying amount of the reporting unit exceeds its fair value. Impairment loss recognized under this new guidance will be limited to the goodwill allocated to the reporting unit. This ASU is effective prospectively for the Company for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. This ASU is not expected to have a material impact on the Company’s consolidated financial statements.
In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This new guidance requires the service cost component of net periodic pension and postretirement benefit costs to be presented separately from other components of net benefit cost in the statement of income. This ASU is effective for the Company for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. This ASU is not expected to have a material impact on the Company’s consolidated financial statements.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This new guidance amends current guidance to better align hedge accounting with risk management activities and reduce the complexity involved in applying hedge accounting. Under this new guidance, the concept of hedge ineffectiveness will be eliminated. Ineffective income generated by cash flow and net investment hedges will be recognized in the same financial reporting period and income statement line item as effective income, so as to reflect the full cost of hedging at one time and in one place. Ineffective income generated by fair value hedges will continue to be reflected in current period earnings; however, it will be recognized in the same income statement line item as effective income. The guidance will also allow any contractually specified variable rate to be designated as the hedged risk in a cash flow hedge. With respect to fair value hedges of interest rate risk, the guidance will allow changes in the fair value of the hedged item to be calculated solely using changes in the benchmark interest rate component of the instrument’s total contractual coupon cash flows. This ASU is effective for the Company for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. This ASU is not expected to have a material impact on the Company’s consolidated financial statements.

The unrealized losses reported pertaining to securities issued by the U.S. government and its sponsored entities, include treasuries, agencies, and mortgage-backed securities issued by Ginnie Mae, Fannie Mae, and Freddie Mac, which are currently rated AAA by Moody’s Investor Services, AA+ by Standard & Poor’s and are guaranteed by the U.S. government. The majority of the obligations of state and political subdivisions and corporations carry a credit rating of A or better. Additionally, a majority of the obligations of state and political subdivisions carry a secondary level of credit enhancement. The Company does not intend to sell these securities, nor is it more likely than not that the Company will be required to sell these securities prior to recovery of the amortized cost. The unrealized losses in the portfolios are primarily attributable to changes in interest rates. As such, management does not believe any individual unrealized loss as of September 30, 2017 represents OTTI.
The amortized cost and estimated fair value of debt securities at September 30, 2017, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately.

The Company uses several credit quality indicators to assess credit risk in an ongoing manner. The Company’s primary credit quality indicator for its business lending portfolio is an internal credit risk rating system that categorizes loans as “pass”, “special mention”, “classified”, or “doubtful”. Credit risk ratings are applied individually to those classes of loans that have significant or unique credit characteristics that benefit from a case-by-case evaluation. In general, the following are the definitions of the Company’s credit quality indicators:

Pass | The condition of the borrower and the performance of the loans are satisfactory or better.
Special Mention | The condition of the borrower has deteriorated although the loan performs as agreed.
Classified | The condition of the borrower has significantly deteriorated and the performance of the loan could further deteriorate, if deficiencies are not corrected.
Doubtful | The condition of the borrower has deteriorated to the point that collection of the balance is improbable based on current facts and conditions.

The following table shows the amount of business lending loans by credit quality category:

Table of Contents
All other loans are underwritten and structured using standardized criteria and characteristics, primarily payment performance, and are normally risk rated and monitored collectively on a monthly basis. These are typically loans to individuals in the consumer categories and are delineated as either performing or nonperforming. Performing loans include loans classified as current as well as those classified as 30 - 89 days past due. Nonperforming loans include 90+ days past due and still accruing and nonaccrual loans. The following table details the balances in all other loan categories at September 30, 2017:

All loan classes are collectively evaluated for impairment except business lending, as described in Note C. A summary of individually evaluated impaired loans as of September 30, 2017 and December 31, 2016 follows:

(000’s omitted) |  | September 30, 2017 |  |  | December 31, 2016 |
Loans with allowance allocation |  | $ | 0 |  |  | $ | 1,109 |
Loans without allowance allocation |  |  | 907 |  |  |  | 556 |
Unpaid principal balance |  |  | 907 |  |  |  | 1,665 |
Contractual balance |  |  | 910 |  |  |  | 3,340 |
Allowance for loan loss allocated |  |  | 0 |  |  |  | 477 |

In the course of working with borrowers, the Company may choose to restructure the contractual terms of certain loans. In this scenario, the Company attempts to work-out an alternative payment schedule with the borrower in order to optimize collectability of the loan. Any loans that are modified are reviewed by the Company to identify if a troubled debt restructuring (“TDR”) has occurred, which is when, for economic or legal reasons related to a borrower’s financial difficulties, the Company grants a concession to the borrower that it would not otherwise consider. Terms may be modified to fit the ability of the borrower to repay in line with its current financial standing and the restructuring of the loan may include the transfer of assets from the borrower to satisfy the debt, a modification of loan terms, or a combination of the two.
In accordance with the clarified guidance issued by the Office of the Comptroller of the Currency (“OCC”), loans that have been discharged in Chapter 7 bankruptcy but not reaffirmed by the borrower, are classified as TDRs, irrespective of payment history or delinquency status, even if the repayment terms for the loan have not been otherwise modified. The Company’s lien position against the underlying collateral remains unchanged. Pursuant to that guidance, the Company records a charge-off equal to any portion of the carrying value that exceeds the net realizable value of the collateral. The amount of loss incurred in the three and nine months ended September 30, 2017 and 2016 was immaterial.

TDRs that are less than $0.5 million are collectively included in the general loan loss allocation and the qualitative review. TDRs that are commercial loans and greater than $0.5 million are individually evaluated for impairment, and if necessary, a specific allocation of the allowance for loan losses is provided. As a result, the determination of the amount of allowance for loan losses related to TDRs is the same as detailed in the critical accounting policies.
Information regarding TDRs as of September 30, 2017 and December 31, 2016 is as follows:

NOTE G: MANDATORILY REDEEMABLE PREFERRED SECURITIES
The Company sponsors three business trusts, Community Statutory Trust III (“CST III”), Community Capital Trust IV (“CCT IV”) and MBVT Statutory Trust I (“MBVT I”), of which 100% of the common stock is owned by the Company. The common stock of MBVT Statutory Trust I was acquired in the Merchants acquisition. The trusts were formed for the purpose of issuing company-obligated mandatorily redeemable preferred securities to third-party investors and investing the proceeds from the sale of such preferred securities solely in junior subordinated debt securities of the Company. The debentures held by each trust are the sole assets of such trust. Distributions on the preferred securities issued by each trust are payable quarterly at a rate per annum equal to the interest rate being earned by the trust on the debentures held by that trust and are recorded as interest expense in the consolidated financial statements. The preferred securities are subject to mandatory redemption, in whole or in part, upon repayment of the debentures. The Company has entered into agreements which, taken collectively, fully and unconditionally guarantee the preferred securities subject to the terms of each of the guarantees. The terms of the preferred securities of each trust are as follows:

Trust | Issuance Date | Par Amount | Interest Rate | Maturity Date | Call Price
CST III | 7/31/2001 | $24.5 million | 3 month LIBOR plus 3.58% (4.89%) | 7/31/2031 | Par
CCT IV | 12/8/2006 | $75.0 million | 3 month LIBOR plus 1.65% (2.97%) | 12/15/2036 | Par
MBVT I | 12/15/2004 | $20.6 million | 3 month LIBOR plus 1.95% (3.27%) | 12/31/2034 | Par

NOTE H: BENEFIT PLANS
The Company provides a qualified defined benefit pension to eligible employees and retirees, other post-retirement health and life insurance benefits to certain retirees, an unfunded supplemental pension plan for certain key executives, and an unfunded stock balance plan for certain of its nonemployee directors. The Company accrues for the estimated cost of these benefits through charges to expense during the years that employees earn these benefits.
Effective May 12, 2017, the Merchants Bank Pension Plan was merged into the Community Bank System, Inc. Pension Plan and the combined plan was revalued resulting in an additional unamortized actuarial gain of approximately $1.9 million, due primarily to a gain on plan assets that was partially offset by a decrease in the discount rate from 4.50% to 4.40% as of the valuation date. The Company made a $2.9 million contribution to its defined benefit pension plan in the first quarter of 2017, and made a $2.0 million contribution to the Merchants Bank Pension Plan in the second quarter of 2017.
The net periodic benefit cost for the three and nine months ended September 30, 2017 and 2016 is as follows:

|  | Pension Benefits |  |  | Post-retirement Benefits |
|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |  |  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |

NOTE I: EARNINGS PER SHARE
The two class method is used in the calculations of basic and diluted earnings per share. Under the two class method, earnings available to common shareholders for the period are allocated between common shareholders and participating securities according to dividends declared and participation rights in undistributed earnings. The Company has determined that all of its outstanding non-vested stock awards are participating securities as of September 30, 2017.

Table of Contents
Basic earnings per share are computed based on the weighted-average of the common shares outstanding for the period. Diluted earnings per share are based on the weighted-average of the shares outstanding adjusted for the dilutive effect of restricted stock and the assumed exercise of stock options during the year. The dilutive effect of options is calculated using the treasury stock method of accounting. The treasury stock method determines the number of common shares that would be outstanding if all the dilutive options (those where the average market price is greater than the exercise price) were exercised and the proceeds were used to repurchase common shares in the open market at the average market price for the applicable time period. There were approximately 0.2 million weighted-average anti-dilutive stock options outstanding for the three months ended September 30, 2017, and 0.1 million weighted-average anti-dilutive stock options outstanding for the nine months ended September 30, 2017, compared to no weighted-average anti-dilutive stock options outstanding for the three months ended September 30, 2016, and approximately 0.3 million weighted-average anti-dilutive stock options outstanding for the nine months ended September 30, 2016 that were not included in the computation below.
The following is a reconciliation of basic to diluted earnings per share for the three and nine months ended September 30, 2017 and 2016:

Stock Repurchase Program
At its December 2016 meeting, the Company’s Board of Directors (the “Board”) approved a stock repurchase program authorizing the repurchase of up to 2.2 million shares of the Company’s common stock in accordance with securities laws and regulations, through December 31, 2017. Any repurchased shares will be used for general corporate purposes, including those related to stock plan activities. The timing and extent of repurchases will depend on market conditions and other corporate considerations as determined at the Company’s discretion. The Company did not repurchase any shares under the authorized plan during the first nine months of 2017.
NOTE J: COMMITMENTS, CONTINGENT LIABILITIES AND RESTRICTIONS
The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments consist primarily of commitments to extend credit and standby letters of credit. Commitments to extend credit are agreements to lend to customers, generally having fixed expiration dates or other termination clauses that may require payment of a fee. These commitments consist principally of unused commercial and consumer credit lines. Standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of an underlying contract with a third party. The credit risks associated with commitments to extend credit and standby letters of credit are essentially the same as that involved with extending loans to customers and are subject to the Company’s normal credit policies. Collateral may be obtained based on management’s assessment of the customer’s creditworthiness. The fair value of the standby letters of credit is immaterial for disclosure.
The contract amounts of commitments and contingencies are as follows:

(000's omitted) |  | September 30, 2017 |  |  | December 31, 2016 |
Commitments to extend credit |  | $ | 1,038,125 |  |  | $ | 773,442 |
Standby letters of credit |  |  | 24,058 |  |  |  | 22,656 |
Total |  | $ | 1,062,183 |  |  | $ | 796,098 |

Table of Contents
The Company and its subsidiaries are subject in the normal course of business to various pending and threatened legal proceedings in which claims for monetary damages are asserted. As of September 30, 2017, management, after consultation with legal counsel, does not anticipate that the aggregate ultimate liability arising out of litigation pending or threatened against the Company or its subsidiaries will be material to the Company’s consolidated financial position. On at least a quarterly basis, the Company assesses its liabilities and contingencies in connection with such legal proceedings. For those matters where it is probable that the Company will incur losses and the amounts of the losses can be reasonably estimated, the Company records an expense and corresponding liability in its consolidated financial statements. To the extent the pending or threatened litigation could result in exposure in excess of that liability, the amount of such excess is not currently estimable. The range of reasonably possible losses for matters where an exposure is not currently estimable or considered probable, beyond the existing recorded liabilities, is between $0 and $1 million in the aggregate. Although the Company does not believe that the outcome of pending litigation will be material to the Company’s consolidated financial position, it cannot rule out the possibility that such outcomes will be material to the consolidated results of operations for a particular reporting period in the future.
NOTE K: FAIR VALUE
Accounting standards establish a framework for measuring fair value and require certain disclosures about such fair value instruments. It defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e. exit price). Inputs used to measure fair value are classified into the following hierarchy:

· Level 1 - | Quoted prices in active markets for identical assets or liabilities.
· Level 2 - | Quoted prices in active markets for similar assets or liabilities, or quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability.
· Level 3 - | Significant valuation assumptions not readily observable in a market.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following tables set forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis. There were no transfers between any of the levels for the periods presented.

The valuation techniques used to measure fair value for the items in the table above are as follows:

· | Available-for-sale investment securities – The fair values of available-for-sale investment securities are based upon quoted prices, if available. If quoted prices are not available, fair values are measured using quoted market prices for similar securities or model-based valuation techniques. Level 1 securities include U.S. Treasury obligations and marketable equity securities that are traded by dealers or brokers in active over-the-counter markets. Level 2 securities include U.S. agency securities, mortgage-backed securities issued by government-sponsored entities, municipal securities and corporate debt securities that are valued by reference to prices for similar securities or through model-based techniques in which all significant inputs, such as reported trades, trade execution data, LIBOR swap yield curve, market prepayment speeds, credit information, market spreads, and security’s terms and conditions, are observable. See Note D for further disclosure of the fair value of investment securities.

· | Mortgage loans held for sale –The Company has elected to value loans held for sale at fair value in order to more closely match the gains and losses associated with loans held for sale with the gains and losses on forward sales contracts. Accordingly, the impact on the valuation will be recognized in the Company’s consolidated statement of income. All mortgage loans held for sale are current and in performing status. The fair value of mortgage loans held for sale is determined using quoted secondary-market prices of loans with similar characteristics and, as such, has been classified as a Level 2 valuation. The unpaid principal value of mortgage loans held for sale at September 30, 2017 was approximately $1.3 million. The unrealized gain on mortgage loans held for sale was recognized in mortgage banking and other income in the consolidated statement and is immaterial.

· | Forward sales commitments – The Company enters into forward sales commitments to sell certain residential real estate loans. Such commitments are considered to be derivative financial instruments and, therefore, are carried at estimated fair value in the other asset or other liability section of the consolidated statement of condition. The fair value of these forward sales commitments is primarily measured by obtaining pricing from certain government-sponsored entities and reflects the underlying price the entity would pay the Company for an immediate sale on these mortgages. As such, these instruments are classified as Level 2 in the fair value hierarchy.

· | Commitments to originate real estate loans for sale – The Company enters into various commitments to originate residential real estate loans for sale. Such commitments are considered to be derivative financial instruments and, therefore, are carried at estimated fair value in the other asset or other liability section of the consolidated statement of condition. The estimated fair value of these commitments is determined using quoted secondary market prices obtained from certain government-sponsored entities. Additionally, accounting guidance requires the expected net future cash flows related to the associated servicing of the loan to be included in the fair value measurement of the derivative. The expected net future cash flows are based on a valuation model that calculates the present value of estimated net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income. Such assumptions include estimates of the cost of servicing loans, appropriate discount rate and prepayment speeds. The determination of expected net cash flows is considered a significant unobservable input contributing to the Level 3 classification of commitments to originate real estate loans for sale.

· | Interest rate swaps – The interest rate swaps are reported at their fair value utilizing Level 2 inputs from third parties. The fair value of our interest rate swaps are determined using prices obtained from a third party advisor. The fair value measurement of the interest rate swap is determined by netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on the expectation of future interest rates derived from observed market interest rate curves.

Loans are generally not recorded at fair value on a recurring basis. Periodically, the Company records nonrecurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of those loans. Nonrecurring adjustments also include certain impairment amounts for collateral-dependent loans calculated when establishing the allowance for loan losses. Such amounts are generally based on the fair value of the underlying collateral supporting the loan and, as a result, the carrying value of the loan less the calculated valuation amount does not necessarily represent the fair value of the loan. Real estate collateral is typically valued using independent appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace, adjusted for non-observable inputs. Thus, the resulting nonrecurring fair value measurements are generally classified as Level 3. Estimates of fair value used for other collateral supporting commercial loans generally are based on assumptions not observable in the marketplace and, therefore, such valuations classify as Level 3.
Other real estate owned (“OREO”) is valued at the time the loan is foreclosed upon and the asset is transferred to OREO. The value is based primarily on third party appraisals, less costs to sell. The appraisals are sometimes further discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the customer and customer’s business. Such discounts are significant, ranging from 9% to 65.9% at September 30, 2017 and result in a Level 3 classification of the inputs for determining fair value. OREO is reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors identified above. The Company recovers the carrying value of OREO through the sale of the property. The ability to affect future sales prices is subject to market conditions and factors beyond the Company’s control and may impact the estimated fair value of a property.
Originated mortgage servicing rights are recorded at their fair value at the time of sale of the underlying loan, and are amortized in proportion to and over the estimated period of net servicing income. The fair value of mortgage servicing rights is based on a valuation model incorporating inputs that market participants would use in estimating future net servicing income. Such inputs include estimates of the cost of servicing loans, appropriate discount rate and prepayment speeds and are considered to be unobservable and contribute to the Level 3 classification of mortgage servicing rights. In accordance with GAAP, the Company must record impairment charges, on a nonrecurring basis, when the carrying value of a stratum exceeds its estimated fair value. Impairment is recognized through a valuation allowance. There is no valuation allowance at September 30, 2017.

The Company determines fair values based on quoted market values, where available, estimates of present values, or other valuation techniques. Those techniques are significantly affected by the assumptions used, including, but not limited to, the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, may not be realized in immediate settlement of the instrument. The significant unobservable inputs used in the determination of fair value of assets classified as Level 3 on a recurring or non-recurring basis are as follows:

Certain financial instruments and all nonfinancial instruments are excluded from fair value disclosure requirements. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company. The carrying amounts and estimated fair values of the Company’s other financial instruments that are not accounted for at fair value at September 30, 2017 and December 31, 2016 are as follows:

The following is a further description of the principal valuation methods used by the Company to estimate the fair values of its financial instruments.
Loans have been classified as a Level 3 valuation. Fair values for variable rate loans that reprice frequently are based on carrying values. Fair values for fixed rate loans are estimated using discounted cash flows and interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.
Deposits have been classified as a Level 2 valuation. The fair value of demand deposits, interest-bearing checking deposits, savings accounts, and money market deposits is the amount payable on demand at the reporting date. The fair value of time deposit obligations are based on current market rates for similar products.
Borrowings and subordinated debt held by unconsolidated subsidiary trusts have been classified as a Level 2 valuation. The fair value of FHLB overnight advances and securities sold under agreement to repurchase, short-term, is the amount payable on demand at the reporting date. Fair values for long-term borrowings and subordinated debt held by unconsolidated subsidiary trusts are estimated using discounted cash flows and interest rates currently being offered on similar securities. The difference between the carrying values of long-term borrowings and subordinated debt held by unconsolidated subsidiary trusts, and their fair values, are not material as of the reporting dates.

Other financial assets and liabilities – Cash and cash equivalents have been classified as a Level 1 valuation, while accrued interest receivable and accrued interest payable have been classified as a Level 2 valuation. The fair values of each approximate the respective carrying values because the instruments are payable on demand or have short-term maturities and present relatively low credit risk and interest rate risk.
NOTE L: DERIVATIVE INSTRUMENTS
The Company is party to derivative financial instruments in the normal course of its business to meet the financing needs of its customers and to manage its own exposure to fluctuations in interest rates. These financial instruments have been limited to interest rate swap agreements, commitments to originate real estate loans held for sale and forward sales commitments. The Company does not hold or issue derivative financial instruments for trading or other speculative purposes.
The Company enters into forward sales commitments for the future delivery of residential mortgage loans, and interest rate lock commitments to fund loans at a specified interest rate. The forward sales commitments are utilized to reduce interest rate risk associated with interest rate lock commitments and loans held for sale. Changes in the estimated fair value of the forward sales commitments and interest rate lock commitments subsequent to inception are based on changes in the fair value of the underlying loan resulting from the fulfillment of the commitment and changes in the probability that the loan will fund within the terms of the commitment, which is affected primarily by changes in interest rates and the passage of time. At inception and during the life of the interest rate lock commitment, the Company includes the expected net future cash flows related to the associated servicing of the loan as part of the fair value measurement of the interest rate lock commitments. These derivatives are recorded at fair value, which were immaterial at September 30, 2017. The effect of the changes to these derivatives for the three and nine months then ended was also immaterial.
The Company acquired interest rate swaps from the Merchants acquisition with notional amounts with certain commercial customers which totaled $39.4 million at September 30, 2017. In order to minimize the Company’s risk, these customer derivatives (pay floating/receive fixed swaps) have been offset with essentially matching interest rate swaps (pay fixed/receive floating swaps) with the Company’s counterparty totaling $39.4 million. The weighted average receive rate of these interest rate swaps was 3.12%, the weighted average pay rate was 3.84% and the weighted average maturity was 6.7 years. The fair values of $0.9 million and $0.9 million were reflected in other assets and other liabilities, respectively, in the accompanying consolidated statement of condition at September 30, 2017. Hedge accounting has not been applied for these derivatives. Since the terms of the swaps with our customer and the other financial institution offset each other, with the only difference being counterparty credit risk, changes in the fair value of the underlying derivative contracts are not materially different and do not significantly impact our results of operations.
The Company also acquired interest rate swaps from the Merchants acquisition with notional amounts totaling $7.0 million at September 30, 2017 that were designated as fair value hedges of certain fixed rate loans with municipalities. At September 30, 2017, the weighted average receive rate of these interest rate swaps was 2.13%, the weighted average pay rate was 3.11% and the weighted average maturity was 15.8 years. The fair value of $0.2 million at September 30, 2017, was reflected as a reduction to loans and an increase to other assets. The ineffective portion of the interest swaps was immaterial and as such, amounts are not recognized in earnings.
The Company assessed its counterparty risk at September 30, 2017 and determined any credit risk inherent in our derivative contracts was not material. Information about the fair value of derivative financial instruments can be found in Note K to these consolidated financial statements.

Item 2. | Management's Discussion and Analysis of Financial Condition and Results of Operations

This Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) primarily reviews the financial condition and results of operations of Community Bank System, Inc. (the “Company” or “CBSI”) as of and for the three and nine months ended September 30, 2017 and 2016, although in some circumstances the second quarter of 2017 is also discussed in order to more fully explain recent trends. The following discussion and analysis should be read in conjunction with the Company's Consolidated Financial Statements and related notes that appear on pages 3 through 30. All references in the discussion of the financial condition and results of operations refer to the consolidated position and results of the Company and its subsidiaries taken as a whole. Unless otherwise noted, the term “this year” and equivalent terms refers to results in calendar year 2017, “third quarter” refers to the three months ended September 30, 2017, “YTD” refers to the nine months ended September 30, 2017, and earnings per share (“EPS”) figures refer to diluted EPS.
This MD&A contains certain forward-looking statements with respect to the financial condition, results of operations, and business of the Company. These forward-looking statements involve certain risks and uncertainties. Factors that may cause actual results to differ materially from those contemplated by such forward-looking statements are set herein under the caption, “Forward-Looking Statements,” on page 47.
Critical Accounting Policies
As a result of the complex and dynamic nature of the Company’s business, management must exercise judgment in selecting and applying the most appropriate accounting policies for its various areas of operations. The policy decision process not only ensures compliance with the latest generally accepted accounting principles (“GAAP”), but also reflects management’s discretion with regard to choosing the most suitable methodology for reporting the Company’s financial performance. It is management’s opinion that the accounting estimates covering certain aspects of the business have more significance than others due to the relative importance of those areas to overall performance, or the level of subjectivity in the selection process. These estimates affect the reported amounts of assets and liabilities as well as disclosures of revenues and expenses during the reporting period. Actual results could differ from these estimates. Management believes that the critical accounting estimates include:

· | Acquired loans – Acquired loans are initially recorded at their acquisition date fair values based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values, and discount rate.

Acquired loans deemed impaired at acquisition are recorded in accordance with ASC 310-30. The excess of undiscounted cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount. The difference between contractually required payments at acquisition and the undiscounted cash flows expected to be collected at acquisition is referred to as the non-accretable discount, which represents estimated future credit losses and other contractually required payments that the Company does not expect to collect. Subsequent decreases in expected cash flows are recognized as impairments through a charge to the provision for loan losses resulting in an increase in the allowance for loan losses. Subsequent improvements in expected cash flows result in a recovery of previously recorded allowance for loan losses or a reversal of a corresponding amount of the non-accretable discount, which the Company then reclassifies as an accretable discount that is recognized into interest income over the remaining life of the loans using the interest method.
For acquired loans that are not deemed impaired at acquisition, the difference between the acquisition date fair value and the outstanding balance represents the fair value adjustment for a loan, and includes both credit and interest rate considerations. Subsequent to the purchase date, the methods used to estimate the allowance for loan losses for the acquired non-impaired loans is consistent with the policy described below. However, for loans collectively evaluated for impairment, the Company compares the net realizable value of the loans to the carrying value. The carrying value represents the net of the loan’s unpaid principal balance and the remaining purchase discount (or premium) that has yet to be accreted into interest income. When the carrying value exceeds the net realizable value, an allowance for loan losses is recognized. For loans individually evaluated for impairment, a provision is recorded when the required allowance exceeds any remaining discount on the loan.

· | Allowance for loan losses – The allowance for loan losses reflects management’s best estimate of probable loan losses in the Company’s loan portfolio. Determination of the allowance for loan losses is inherently subjective. It requires significant estimates, including the amounts and timing of expected future cash flows on impaired loans, appraisal values of underlying collateral for collateralized loans, and the amount of estimated losses on pools of homogeneous loans which is based on historical loss experience and consideration of current economic trends, all of which may be susceptible to significant change.

· | Investment securities – Investment securities are classified as held-to-maturity, available-for-sale, or trading. The appropriate classification is based partially on the Company’s ability to hold the securities to maturity and largely on management’s intentions with respect to either holding or selling the securities. The classification of investment securities is significant since it directly impacts the accounting for unrealized gains and losses on securities. Unrealized gains and losses on available-for-sale securities are recorded in accumulated other comprehensive income or loss, as a separate component of shareholders’ equity, and do not affect earnings until realized. The fair values of investment securities are generally determined by reference to quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments, or a discounted cash flow model using market estimates of interest rates and volatility. Investment securities with significant declines in fair value are evaluated to determine whether they should be considered other-than-temporarily impaired (“OTTI”). An unrealized loss is generally deemed to be other-than-temporary and a credit loss is deemed to exist if the present value of the expected future cash flows is less than the amortized cost basis of the debt security. The credit loss component of an OTTI write-down is recorded in earnings, while the remaining portion of the impairment loss is recognized in other comprehensive income (loss), provided the Company does not intend to sell the underlying debt security, and it is not more likely than not that the Company will be required to sell the debt security prior to recovery of the full value of its amortized cost basis.

· | Retirement benefits – The Company provides defined benefit pension benefits to eligible employees and post-retirement health and life insurance benefits to certain eligible retirees. The Company also provides deferred compensation and supplemental executive retirement plans for selected current and former employees. Expense under these plans is charged to current operations and consists of several components of net periodic benefit cost based on various actuarial assumptions regarding future experience under the plans, including, but not limited to, discount rate, rate of future compensation increases, mortality rates, future health care costs, and the expected return on plan assets.

· | Intangible assets – As a result of acquisitions, the Company carries goodwill and identifiable intangible assets. Goodwill represents the cost of acquired companies in excess of the fair value of net assets at the acquisition date. Goodwill is evaluated at least annually, or when business conditions suggest impairment may have occurred. Should impairment occur, goodwill will be reduced to its carrying value through a charge to earnings. Core deposits and other identifiable intangible assets are amortized to expense over their estimated useful lives. The determination of whether or not impairment exists is based upon discounted cash flow modeling techniques that require management to make estimates regarding the amount and timing of expected future cash flows. It also requires them to select a discount rate that reflects the current return requirements of the market in relation to current credit risk-free interest rates, required equity market premiums, and company-specific performance and risk metrics, all of which are susceptible to change based on changes in economic and market conditions and other factors. Future events or changes in the estimates used to determine the carrying value of goodwill and identifiable intangible assets could have a material impact on the Company’s results of operations.

A summary of the accounting policies used by management is disclosed in Note A, “Summary of Significant Accounting Policies” on pages 59-65 of the most recent Form 10-K (fiscal year ended December 31, 2016) filed with the Securities and Exchange Commission (“SEC”) on March 1, 2017.

The Company also provides supplemental reporting of its results on a “net adjusted” or “tangible” basis, from which it excludes the after-tax effect of amortization of core deposit and other intangible assets (and the related goodwill, core deposit intangible and other intangible asset balances, net of applicable deferred tax amounts), accretion on non-impaired purchased loans, and expenses associated with acquisitions. Although “adjusted net income” as defined by the Company is a non-GAAP measure, the Company’s management believes this information helps investors understand the effect of acquisition activity in its reported results. Reconciliations of GAAP amounts with corresponding non-GAAP amounts are presented in Table 11.
Executive Summary
The Company’s business philosophy is to operate as a diversified financial services enterprise providing a broad array of banking and financial services to retail, commercial and municipal customers. The Company’s banking subsidiary is Community Bank, N.A. (the “Bank” or “CBNA”). The Company also provides employee benefit, wealth management and insurance-related services.
The Company’s core operating objectives are: (i) grow the branch network, primarily through a disciplined acquisition strategy, and certain selective de novo expansions, (ii) build profitable loan and deposit volume using both organic and acquisition strategies, (iii) increase the noninterest component of total revenues through development of banking-related fee income, growth in existing financial services business units, and the acquisition of additional financial services and banking businesses, and (iv) utilize technology to deliver customer-responsive products and services and improve efficiencies.

Significant factors reviewed by management to evaluate achievement of the Company’s operating objectives and its operating results and financial condition include, but are not limited to: net income and earnings per share, return on assets and equity, net interest margins, noninterest revenues, noninterest expenses, asset quality, loan and deposit growth, capital management, performance of individual banking and financial services units, performance of specific product lines and customers, liquidity and interest rate sensitivity, enhancements to customer products and services and their underlying performance characteristics, technology advancements, market share, peer comparisons, and the performance of recently acquired businesses.
On January 1, 2017, the Company, through its subsidiary, OneGroup NY, Inc. (“OneGroup”), acquired certain assets of Benefits Advisory Service, Inc. (“BAS”), a benefits consulting group headquartered in Forest Hills, New York. The Company paid $1.2 million in cash to acquire the assets of BAS and recorded intangible assets of $1.2 million in conjunction with the acquisition.
On February 3, 2017, the Company completed its acquisition of Northeast Retirement Services, Inc. (“NRS”) and its subsidiary Global Trust Company, Inc. (“GTC”), headquartered in Woburn, Massachusetts, for $148.6 million in Company stock and cash. NRS was a privately held corporation focused on providing institutional transfer agency, master recordkeeping services, custom target date fund administration, trust product administration and customized reporting services to institutional clients. Its wholly-owned subsidiary, GTC, is chartered in the State of Maine as a non-depository trust company and provides fiduciary services for collective investment trusts and other products. The acquisition of NRS and GTC, hereafter referred to collectively as NRS, will strengthen and complement the Company’s existing employee benefit services businesses. Upon the completion of the merger, NRS became a wholly-owned subsidiary of Benefit Plans Administrative Services, Inc. (“BPAS”) and operates as Northeast Retirement Services, LLC, a Delaware limited liability company. This transaction resulted in the acquisition of $36.1 million in net tangible assets, principally cash and certificates of deposit, $60.2 million in customer list intangibles that will be amortized over 10 years, a $24.2 million deferred tax liability associated with the customer list intangible, and $76.5 million in goodwill.
On March 1, 2017, the Company, through its subsidiary, OneGroup, completed its acquisition of certain assets of Dryfoos Insurance Agency, Inc. (“Dryfoos”), an insurance agency headquartered in Hazleton, Pennsylvania. The Company paid $3.0 million in cash to acquire the assets of Dryfoos, and recorded goodwill in the amount of $1.7 million and other intangible assets of $1.7 million in conjunction with the acquisition.
On May 12, 2017, the Company completed its acquisition of Merchants Bancshares, Inc. (“Merchants”), parent company of Merchants Bank headquartered in South Burlington, Vermont, for $345.2 million in Company stock and cash, comprised of $82.9 million in cash and the issuance of 4.68 million shares of common stock. The acquisition extends the Company’s footprint into the Vermont and Western Massachusetts markets with the addition of 31 branch locations in Vermont and one location in Massachusetts. This transaction resulted in the acquisition of $1.99 billion of assets, including $1.49 billion of loans and $370.6 million of investment securities, as well as $1.45 billion of deposits and $188.3 million in goodwill.
Third quarter and year-to-date net income increased compared to the comparable 2016 timeframes by $8.1 million and $1.3 million, respectively. Earnings per share of $0.68 for the third quarter of 2017 increased $0.07 from the third quarter of 2016, while 2017 year-to-date earnings per share of $1.60 was $0.14 lower than 2016 year-to-date earnings per share. The increase in net income and earnings per share for the quarter were primarily due to increases in net interest income and higher noninterest revenues, partially offset by a higher provision for loan losses, higher noninterest expenses including acquisition costs and an increase in diluted shares outstanding, primarily attributable to the Merchants and NRS acquisitions. The increase in net income and decrease in earnings per share for the year-to-date period were primarily due to higher net interest income and higher noninterest revenues, primarily related to the Merchants and NRS acquisitions, offset by increases in noninterest expenses, including $25.2 million of acquisition expenses associated with the Merchants and NRS transactions, and diluted shares outstanding. Third quarter and year-to-date net income adjusted to exclude acquisition expenses, amortization of intangibles and acquired non-impaired loan accretion, increased $10.1 million as compared to the third quarter of 2016 and increased $22.6 million compared to September YTD 2016, respectively. Earnings per share adjusted to exclude acquisition expenses, amortization of intangibles and acquired non-impaired loan accretion of $0.73 for the third quarter increased $0.11 compared to the third quarter of 2016. Earnings per share adjusted for acquisition expenses, amortization of intangibles and acquired non-impaired loan accretion of $2.07 for the first nine months of 2017 increased $0.31 compared to the first nine months of 2016.
The growth in loans and deposits was evident as balances showed increases on both an average and ending basis as compared to the corresponding prior year periods. The increases were a result of the Merchants acquisition completed in May 2017, as well as organic growth.
The trends of declining yields on interest-earning assets and rates of interest-bearing liabilities have moderated recently. U.S. market interest rates have generally increased 50 to 75 basis points over the past year. The cost of funds increased slightly from prior year periods, as the increase in short-term interest rates paid on borrowings was almost entirely offset by the benefit from a larger proportion of deposits coming from lower rate and noninterest-bearing accounts, instead of higher cost money market and time deposits.

The third quarter 2017 provision for loan losses was $0.5 million higher than the third quarter of 2016, reflective of higher levels of net charge-offs and growth in loan portfolio balances. Third quarter 2017 nonperforming loan ratios improved modestly compared to the third quarter of 2016, while delinquent loan ratios increased modestly compared to those experienced in the third quarter of 2016. Net charge-offs were $1.8 million for the third quarter of 2017, compared to $1.5 million of net charge-offs for the third quarter of 2016.
Net Income and Profitability
As shown in Table 1, net income for the third quarter and September YTD of $35.2 million and $78.7 million, respectively, increased $8.1 million, or 29.8%, as compared to the third quarter of 2016 and increased $1.3 million, or 1.6%, compared to September YTD 2016. Earnings per share of $0.68 for the third quarter increased $0.07 compared to the third quarter of 2016, while earnings per share for the first nine months of 2017 of $1.60 was $0.14 lower than the first nine months of 2016. The increase in net income and earnings per share for the quarter are primarily the result of higher net interest income and noninterest revenues, partially offset by higher noninterest expenses including acquisition costs and an increase in diluted shares outstanding, primarily attributable to the Merchants and NRS acquisitions. The decrease in earnings per share September YTD compared to the prior year period is the result of higher noninterest expenses, including $25.2 million in acquisition costs and an increase in diluted shares outstanding primarily related to the issuance of shares in conjunction with the Merchants and NRS acquisitions, partially offset by higher net interest income and higher noninterest revenues. Net income adjusted to exclude acquisition expenses, amortization of intangibles and acquired non-impaired loan accretion of $37.8 million and $101.7 million for the third quarter and September YTD, respectively, increased $10.1 million, or 36.4%, as compared to the third quarter of 2016 and increased $22.6 million, or 28.6%, compared to September YTD 2016. Earnings per share adjusted to exclude acquisition expenses, amortization of intangibles and acquired non-impaired loan accretion of $0.73 for the third quarter, was up $0.11 compared to the third quarter of 2016, while earnings per share adjusted to exclude acquisition expenses, amortization of intangibles and acquired non-impaired loan accretion of $2.07 for the first nine months of 2017, was up $0.31 compared to the first nine months of 2016.
As reflected in Table 1, third quarter net interest income of $84.4 million was up $15.9 million, or 23.3%, from the comparable prior year period. Net interest income for the first nine months of 2017 increased $26.0 million, or 12.8%, versus the first nine months of 2016. The quarterly and year-over-year improvement resulted from an increase in interest-earning assets, primarily from the Merchants acquisition, partially offset by a decrease in investment yields.
The provision for loan losses for the third quarter and September YTD increased $0.5 million and $0.2 million as compared to the third quarter and first nine months of 2016, respectively, reflective of a higher level of net charge-offs and growth in loan portfolio balances compared to the prior year periods.
Third quarter and year-to-date noninterest revenues were $52.9 million and $148.5 million, respectively, up $13.0 million, or 32.5%, from the third quarter of 2016 and up $31.5 million, or 26.9%, from the first nine months of 2016. The increase was a result of the Merchants acquisition completed in May 2017 and the NRS, Dryfoos and BAS acquisitions completed in the first quarter of 2017, as well as organic revenue growth generated by the Company’s other financial services subsidiaries and an increase in banking noninterest income.
Noninterest expenses of $83.8 million and $260.2 million for the third quarter and September YTD periods reflected an increase of $17.6 million, or 26.5%, from the third quarter of 2016 and an increase of $60.0 million, or 30.0%, from the first nine months of 2016. Excluding acquisition-related expenses, 2017 operating expenses were $17.0 million, or 25.6%, higher for the third quarter and $35.1 million, or 17.6%, higher for the year-to-date timeframe. The increases in noninterest expenses were mostly a result of operating a larger franchise, including the impact of the Merchants and NRS acquisitions.

Net Interest Income
Net interest income is the amount by which interest and fees on earning assets (loans, investments, and cash equivalents) exceeds the cost of funds, which consists primarily of interest paid to the Company's depositors and on external borrowings. Net interest margin is the difference between the yield on earning assets and the cost of interest-bearing funds as a percentage of earning assets.
As shown in Table 2a, net interest income (with nontaxable income converted to a fully tax-equivalent basis) for the third quarter was $86.8 million, a $15.9 million, or 22.4%, increase from the same period last year. The increase resulted from an increase in interest-earning assets of $1.77 billion from the third quarter of 2016, primarily related to the Merchants acquisition, partially offset by a one basis point decrease in the average yield on earning assets, a $1.04 billion increase in average interest-bearing liabilities, and a four basis point increase in the average rate paid on interest-bearing liabilities. As reflected in Table 3, the third quarter volume increase in interest-earning assets had a $17.1 million favorable impact on net interest income, while the slight decrease in the average yield on earning assets, volume increase on interest-bearing liabilities, and rate increase on interest-bearing liabilities had a $1.2 million unfavorable impact on net interest income. September YTD net interest income, as reflected in Table 2b, of $236.8 million, increased $25.6 million, or 12.1%, from the year-earlier period. The September YTD increase resulted from an increase in interest-earning assets of $977.0 million from the prior year, reflective of the Merchants acquisition, partially offset by a one basis point decrease in the earning asset yield, a $539.4 million increase in average interest-bearing liabilities and a two basis point increase in the rate paid on interest-bearing liabilities. The volume increase in interest-earning assets had a $28.0 million favorable impact on September YTD net interest income, while the rate decrease on interest-earning assets, the volume increase on interest-bearing liabilities and rate increase on interest-bearing liabilities had a $2.4 million unfavorable impact on net interest income.
The lower net interest margin for the third quarter of 2017 as compared to the third quarter of 2016 was the result of a one basis point decrease in the earning asset yield, combined with a four basis point increase in the average rate on interest-bearing liabilities. The net interest margin of 3.67% for the first nine months of 2017 was two basis points lower than the comparable period of 2016. The yield on interest-earning assets declined one basis point, and the rate on interest-bearing liabilities increased by two basis points for the first nine months of 2017 as compared to the prior year period.
The lower average yield on earning assets for the quarter was the result of a decrease in the average yield on investments partially offset by a modest increase in the average yield on loans. For the third quarter, the average yield on investments, including cash equivalents, declined 18 basis points compared to the prior year, while the average yield on loans increased by one basis point. The one basis point decrease in the yield on earning assets for the first nine months of 2017 was the result of a 16 basis point decrease in the average yield on investments, including cash equivalents, from the comparable period of 2016, partially offset by a two basis point increase in the average yield on loans. The modest increase in the loan yield was due primarily to an increase in acquired loan accretion on the acquired Merchants portfolio. The lower average yield of investments was the result of maturing higher interest rate investments being replaced with lower rate instruments or being used to pay down external borrowings.
The average rate on interest-bearing liabilities increased by four basis points compared to the prior year quarter as the average rate paid on external borrowings increased 13 basis points and the rate paid on interest-bearing deposits increased one basis point from the period year quarter. For the first nine months of 2017, the average rate on borrowings increased 22 basis points and the average rate on interest-bearing deposits decreased one basis point from the comparable prior year period. The increase in the average cost of borrowings was primarily the result of lower-rate overnight FHLB borrowings becoming a smaller proportion of this funding component, as well as increased costs resulting from increases in the federal funds rate in December 2016, March 2017 and June 2017.
The third quarter and year-to-date average balance of investments, including cash equivalents, increased $340.1 million and $176.8 million, respectively, as compared to the corresponding prior year periods. This growth was principally the result of securities acquired in the Merchants transaction. Average loan balances increased $1.43 billion for the quarter and $800.2 million year-to-date as compared to the prior year, with $1.43 billion for the quarter and $735.4 million year-to-date a result of the Merchants acquisition.
The quarterly and year-to-date increases in average interest-bearing deposits of $825.4 million and $474.3 million, respectively, were primarily a result of the Merchants transaction, as well as the addition of new customers and growth in the balances of existing accounts. The Merchants transaction was responsible for $751.4 million of the quarterly increase and $392.1 million of the year-to-date increase in average interest-bearing deposits. The average borrowing balance, including overnight borrowings at the FHLB, subordinated debt held by unconsolidated subsidiary trusts, securities sold under agreement to repurchase and other long-term debt, increased $213.5 million for the quarter, with $265.5 million in average borrowings for the quarter related to the Merchants acquisition, partially offset by a decrease in overnight FHLB borrowings. The average borrowing balance increased $65.1 million for the year-to-date period with $138.1 million in average borrowings related to the Merchants acquisition, partially offset by a decrease in overnight FHLB borrowings due to additional funding from acquired and organic deposit growth.

Table of Contents
Tables 2a and 2b below sets forth information related to average interest-earning assets and interest-bearing liabilities and their associated yields and rates for the periods indicated. Interest income and yields are on a fully tax-equivalent basis (“FTE”) using marginal income tax rates of 37.8% and 38.2% in 2017 and 2016, respectively. Average balances are computed by totaling the daily ending balances in a period and dividing by the number of days in that period. Loan interest income and yields include amortization of deferred loan income and costs and the accretion of acquired loan marks. Average loan balances include nonaccrual loans and loans held for sale.

Noninterest Revenues
The Company’s sources of noninterest revenues are of four primary types: 1) general banking services related to loans, deposits, and other core customer activities typically provided through the branch network and electronic banking channels (performed by CBNA); 2) employee benefit services (performed by BPAS and its subsidiaries); 3) wealth management services, comprised of trust services (performed by the trust unit within CBNA), investment products and services (performed by Community Investment Services, Inc. (“CISI”)) and asset management services (performed by Nottingham Advisors, Inc.); and 4) insurance products and services (performed by OneGroup). Additionally, the Company has periodic transactions, most often net gains or losses from the sale of investment securities and prepayment of debt instruments.

Table of Contents
As displayed in Table 4, noninterest revenues were $52.9 million for the third quarter of 2017 and $148.5 million for the first nine months of 2017. This represents an increase of $13.0 million, or 32.5%, for the quarter and $31.5 million, or 26.9%, for the YTD period in comparison to 2016, with the increase primarily related to incremental banking revenues from the Merchants acquisition and financial services revenues from the NRS acquisition.
General recurring banking noninterest revenue of $19.8 million for the third quarter and $52.6 million for the first nine months of 2017 were up $2.7 million, or 15.6%, and $4.5 million, or 9.4%, respectively, as compared to the corresponding prior year periods. This year-over-year increase was primarily driven by an expanded customer base following the Merchants transaction, which was completed in May 2017, and an increase in deposit service fees resulting from increased debit card-related revenue.
Mortgage banking income totaled $0.4 million for the third quarter of 2017 and $1.4 million for the first nine months of 2017, a decrease of $0.3 million and $0.2 million, respectively, as compared to the corresponding prior periods. Mortgage banking income consists of realized gains or losses from the sale of residential mortgage loans and the origination of mortgage loan servicing rights, unrealized gains and losses on residential mortgage loans held for sale and related commitments, mortgage loan servicing fees and other residential mortgage loan-related fee income. Mortgage loans sold to investors, primarily Fannie Mae, totaled $8.9 million in the third quarter of 2017 and $24.3 million for the first nine months of 2017 compared to $12.0 million and $28.6 million in the respective comparable prior year periods. Realization of the unrealized gains or losses on mortgage loans held for sale and the related commitments, as well as future revenue generation from mortgage banking activities, are dependent on market conditions and long-term interest rate trends.
Employee benefit services revenue increased $9.5 million, or 84.3%, and $23.7 million, or 67.7%, for the three and nine months ended September 30, 2017, respectively, as compared to the prior year periods, primarily related to the NRS acquisition completed in February 2017. Wealth management and insurance services revenues were up $1.1 million, or 10.3%, for the third quarter of 2017 and up $3.4 million, or 10.6%, 2017 YTD as compared to the comparable time periods of 2016, primarily due to revenue growth from OneGroup.
The ratio of noninterest revenues to total revenues (FTE basis) was 38.4% for the quarter and 38.9% for the nine months ended September 30, 2017, respectively, versus 36.5% and 36.0% for the comparable periods of 2016. The increase for the year-to-date period is a function of a 26.9% increase in non-interest income while net interest income (FTE basis) increased at a lesser 12.1% rate, primarily the result of the mix of business acquired in the NRS and Merchants transactions.
Noninterest Expenses
Table 5 below sets forth the quarterly results of the major noninterest expense categories for the current and prior year, as well as efficiency ratios (defined below), a standard measure of expense utilization effectiveness commonly used in the banking industry.

Table of Contents
As shown in Table 5, noninterest expenses were $83.8 million and $260.2 million for the third quarter and YTD periods of 2017, respectively, representing an increase of $17.6 million, or 26.5%, and $60.0 million, or 30.0%, from the prior year periods. Included in the third quarter and YTD 2017 noninterest expenses are $0.6 million and $24.9 million more acquisition-related expenses, respectively, than the corresponding 2016 periods. Salaries and employee benefits increased $8.3 million, or 21.6%, and $17.4 million, or 15.1%, for the third quarter and YTD periods of 2017, respectively, as compared to the corresponding periods of 2016. The main drivers of the increase were more full-time equivalent employees due to the Merchants and NRS acquisitions and annual merit-based personnel cost increases. The remaining change to operating expenses can be attributed to occupancy and equipment (up $1.7 million for the quarter and $3.5 million YTD), data processing and communications (up $0.6 million for the quarter and $2.3 million YTD), amortization of intangible assets (up $3.6 million for the quarter and $7.8 million YTD), legal and professional (up $0.8 million for the quarter and $1.5 million YTD), office supplies and postage (up $0.3 million for the quarter and $0.2 million YTD), business development and marketing (up $0.6 million for the quarter and $1.0 million YTD), FDIC insurance premiums (up $0.1 million for the quarter and down $0.4 million YTD), other expenses (up $1.0 million for the quarter and $1.9 million YTD); all of which were primarily driven by the additional costs that are associated with the acquired Merchants and NRS business activities.
The Company’s efficiency ratio (total operating expenses excluding intangible amortization and acquisition expenses divided by FTE net interest income excluding acquired non-impaired loan accretion and non-interest income excluding gains on sales of investments and insurance related recoveries) was 56.8% for the third quarter, 2.5% favorable to the comparable quarter of 2016. This resulted from operating income increasing by 26.1% from higher FTE-adjusted net interest income and growth in noninterest revenues, while operating expenses (as described above) increased by a smaller 20.6%. The efficiency ratio of 58.5% for the first nine months of 2017 was 1.7% favorable to the first nine months of 2016 due to 11.3% higher FTE-adjusted net interest income excluding acquired non-impaired loan accretion and a 27.9% increase in noninterest revenues excluding gains on sales of investments and insurance related recoveries resulting in an increase in operating income of 17.2%, while operating expenses (as described above) increased at a lesser 14.0%. Current year operating expenses, excluding intangible amortization and acquisition expenses, as a percentage of average assets decreased 10 basis points versus the prior year quarter and was consistent with the prior year-to-date period. Operating expenses (as defined above) increased 20.6% for the quarter and 14.0% for the year-to-date period, while average assets increased 24.7% for the quarter and 13.9% for the year-to-date period, impacted by asset growth related to the Merchants and NRS acquisitions, offset by additional operating costs associated with operating a larger enterprise.
Income Taxes
The third quarter and YTD 2017 effective income tax rates were 31.2% and 30.0%, respectively, as compared to the 32.8% and 32.7% for the comparable periods of 2016. The decline in the rate was primarily attributable to new accounting guidance for share-based transactions that requires all excess tax benefits and deficiencies associated with share-based compensation be recognized as income tax expense or benefit, partially offset by a higher proportion of income being generated from fully-taxable sources. Excluding the $0.3 million and $2.9 million reduction in income tax expense associated with the change in accounting for share-based transactions for the third quarter and YTD 2017, respectively, the adjusted effective tax rates for the third quarter and YTD 2017 would have been 31.9% and 32.5%, respectively.
Investments
The carrying value of investments (including unrealized gains and losses on available-for-sale securities) was $3.13 billion at the end of the third quarter, an increase of $340.8 million from December 31, 2016 and $247.6 million higher than September 30, 2016. The book value (excluding unrealized gains and losses) of investments increased $329.7 million from December 31, 2016 and increased $334.8 million from September 30, 2016. During the first nine months of 2017, the Company purchased $4.8 million of obligations of state and political subdivisions with an average yield of 4.23%, and $52.5 million of government agency mortgage-backed securities with an average yield of 2.58%. The Company also received $110.1 million of investment maturities, calls, and principal payments during the first nine months of 2017. Additionally, $390.9 million of investment securities were acquired as part of the Merchants transaction and $20.3 million of certificates of deposit were acquired as part of the NRS acquisition, of which $16.5 million were subsequently redeemed.
The change in the carrying value of investments is also impacted by the amount of net unrealized gains in the available-for-sale portfolio. At September 30, 2017, the portfolio had a $53.0 million net unrealized gain, an increase of $11.2 million from the unrealized gain at December 31, 2016 and an $87.2 million decrease from the unrealized gain at September 30, 2016. These changes in the net unrealized gain were principally driven by the movement in longer-term interest rates over the past year.

The growth during the last nine and twelve months was primarily attributable to acquired loans, with $1.42 billion of the increase from the Merchants transaction partially offset by a decline in balances.

Consumer mortgages increased $407.8 million, or 22.7%, from one year ago and increased $386.8 million, or 21.3%, from December 31, 2016. Excluding the $353.8 million in consumer mortgage loans acquired from Merchants, consumer mortgages increased $54.0 million, or 3.0%, from one year ago and increased $33.1 million, or 1.8%, from December 31, 2016. Consumer mortgage volume has been relatively strong over the last several years due to historically low long-term rates and comparatively stable real estate valuations in the Company’s primary markets. Interest rate levels and expected duration continue to be the most significant factors in determining whether the Company chooses to retain, versus sell and service, portions of its new mortgage production.
The combined total of general-purpose business lending to commercial and industrial customers, municipal lending, mortgages on commercial property, and dealer floor plan financing is characterized as the Company’s business lending activity. The business lending portfolio increased $952.1 million, or 63.2%, from September 30, 2016 and increased $968.9 million, or 65.0%, from December 31, 2016, with $1.02 billion in loans from Merchants, partially offset by contractual and unscheduled principal reductions. Highly competitive conditions continue to prevail in the small and middle market segments in which the Company operates. The Company maintains its commitment to generating growth in its business portfolio in a manner that adheres to its twin goals of maintaining strong asset quality and producing profitable margins. The Company continues to invest in additional personnel, technology and business development resources to further strengthen its capabilities in this important product category.

Consumer installment loans, both those originated directly in the branches (referred to as “consumer direct”) and indirectly in automobile, marine, and recreational vehicle dealerships (referred to as “consumer indirect”), decreased $14.6 million, or 1.2%, from one year ago and decreased $18.2 million, or 1.5%, from December 31, 2016, with $2.8 million in loans added in the Merchants transaction. The Company is focused on maintaining the solid profitability produced by its in-market and contiguous market indirect portfolio, while continuing to pursue its disciplined, long-term approach to expanding its dealer network. However, the increasingly competitive nature of this market has resulted in aggressive pricing and incentives that have caused some compression of indirect loan spreads and prompted the Company to reduce new indirect loan volume, particularly in the automobile segment.
Home equity loans increased $22.8 million, or 5.7%, from one year ago and increased $22.6 million, or 5.6%, from December 31, 2016. The growth included the $39.8 million of loans acquired in the Merchants transaction, partially offset by home equity loans being paid off or down as part of the heightened level of consumer mortgage refinancing that in some cases are used to pay down or pay off home equity balances in the continued low rate environment.
Asset Quality
Table 8 below exhibits the major components of nonperforming loans and assets and key asset quality metrics for the periods ending September 30, 2017 and 2016 and December 31, 2016.

As displayed in Table 8, nonperforming assets at September 30, 2017 were $25.2 million, a $0.4 million decrease versus the level at the end of 2016 and a $0.1 million decrease as compared to one year earlier. Nonperforming loans decreased $0.3 million from year-end 2016 and increased $0.1 million from September 30, 2016. Other real estate owned (“OREO”) at September 30, 2017 of $1.9 million decreased $0.1 million from December 31, 2016 and decreased $0.2 million from September 30, 2016. At September 30, 2017, OREO consisted of three commercial properties with a total value of $0.9 million and 23 residential properties with a total value of $1.0 million. This compares to five commercial properties with a total value of $0.8 million and 24 residential OREO properties with a total value of $1.2 million at December 31, 2016 and three commercial properties with a total value of $0.7 million and 24 residential properties with a total value of $1.4 million at September 30, 2016. Nonperforming loans were 0.37% of total loans outstanding at the end of the third quarter; 11 basis points lower than the level at December 31, 2016 and a 10 basis point improvement from the level at September 30, 2016.
Approximately 66% of nonperforming loans at September 30, 2017 are related to the consumer mortgage portfolio. Collateral values of residential properties within the Company’s market area have generally remained stable over the past several years. Additionally, improved process efficiency and economic conditions, including lower unemployment levels, have positively impacted consumers and have generally resulted in more favorable nonperforming mortgage ratios. Approximately 21% of the nonperforming loans at September 30, 2017 were related to the business lending portfolio, which is comprised of business loans broadly diversified by industry type. The level of nonperforming business loans has decreased from the prior year and is below the Company’s longer-term average results as a proportion of total loans due to general economic improvements, effective problem loan management and maintenance of strict underwriting standards. The remaining 13% of nonperforming loans relate to consumer installment and home equity loans, with home equity non-performing loan levels being driven by the same factors identified for consumer mortgages. The allowance for loan losses to nonperforming loans ratio, a general measure of coverage adequacy, was 205% at the end of the third quarter, as compared to 199% at year-end 2016 and 201% at September 30, 2016.
The Company’s senior management, special asset officers and lenders review all delinquent and nonaccrual loans and OREO regularly in order to identify deteriorating situations, monitor known problem credits and discuss any needed changes to collection efforts, if warranted. Based on the group’s consensus, a relationship may be assigned a special assets officer or other senior lending officer to review the loan, meet with the borrowers, assess the collateral and recommend an action plan. This plan could include foreclosure, restructuring loans, issuing demand letters or other actions. The Company’s larger criticized credits are also reviewed on a quarterly basis by senior credit administration management, special assets officers and commercial lending management to monitor their status and discuss relationship management plans. Commercial lending management reviews the criticized loan portfolio on a monthly basis.
Delinquent loans (30 days past due through nonaccruing) as a percent of total loans was 1.05% at the end of the third quarter, 14 basis points below the 1.19% at year-end 2016 and one basis points below the 1.06% at September 30, 2016. The business lending delinquency ratio at the end of the third quarter was five basis points above the level at December 31, 2016 and 11 basis points above the level at September 30, 2016. The delinquency rates for consumer direct and consumer indirect loans decreased as compared to the level at December 31, 2016, but increased from the level at September 30, 2016. The delinquency ratios for the consumer mortgage and home equity portfolios decreased as compared to both December 31, 2016 and the level one year ago. The Company’s success at keeping the nonperforming and delinquency ratios at favorable levels has been the result of its continued focus on maintaining strict underwriting standards, as well as the effective utilization of its collection and recovery capabilities.

As displayed in Table 9, net charge-offs during the third quarter of 2017 were $1.8 million, $0.3 million higher than the third quarter of 2016. Net charge-offs for the nine months ended September 30, 2017 were $4.9 million, a $0.8 million increase from the first nine months of 2016. All portfolios except business lending experienced higher levels of net charge-offs through the first nine months of 2017 as compared to the first nine months of 2016. The net charge-off ratio (net charge-offs as a percentage of average loans outstanding) for the third quarter of 2017 was 0.11%, seven basis points lower than the fourth quarter of 2016 and one basis points lower than the third quarter of 2016. Net charge-off ratios for the third quarter of 2017 for all portfolios except consumer direct were below the Company’s average long-term historical levels. The September YTD net charge-off ratio of 0.11% for total loans was consistent with the equivalent prior year period.
The provision for loan losses was $2.3 million in the third quarter, with $2.0 million related to legacy loans and $0.3 million related to acquired loans. The third quarter provision was $0.5 million higher than the equivalent prior year period. The third quarter 2017 loan loss provision was $0.5 million more than the level of net charge-offs for the quarter. The allowance for loan losses of $48.0 million as of September 30, 2017 was an increase of $1.2 million from the level one year ago, reflective of an increase in the size of the loan portfolio. Stable asset quality metrics, as well as an increase in the loan portfolio primarily due to acquired growth, have resulted in an allowance for loan loss to total loans ratio of 0.76% at September 30, 2017, 19 basis points lower than the level at September 30, 2016 and December 31, 2016.
As of September 30, 2017, the purchase discount related to the $1.76 billion of remaining non-impaired loan balances acquired from Merchants, Oneida Savings Bank, HSBC Bank USA, N.A., First Niagara Bank, N.A., and Wilber National Bank was approximately $33.8 million, or 1.9% of that portfolio, with $2.0 million included in the allowance for loan losses for acquired loans where the carrying value exceeded the estimated net recoverable value.

Deposits
As shown in Table 10, average deposits of $8.54 billion in the third quarter were up $1.56 billion, or 22.4%, compared to the third quarter of 2016, and increased $1.46 billion, or 20.7%, from the fourth quarter of last year, with $1.37 billion of the increase from the third quarter of 2016 and the fourth quarter of last year relating to the Merchants transaction. The mix of average deposit balances continues to change as the weightings of core deposits (noninterest checking, interest checking, savings and money markets) have increased from the prior year levels. Conversely, the proportion of time deposits decreased over the past 12 months, consistent with the last several years. This change in deposit mix reflects the Company’s goal of expanding core account relationships and reducing higher cost time deposit balances, as well as the preference of certain customers to hold a higher proportion of their funds in liquid accounts in the low interest rate environment. This shift in product mix contributed to a quarterly average cost of deposits of 0.10%, consistent with the third quarter of 2016. The Company continues to focus heavily on growing its core deposit relationships through its proactive marketing efforts, competitive product offerings and high quality customer service.
Average nonpublic fund deposits for the third quarter of 2017 increased $1.45 billion, or 23.9%, versus the fourth quarter of 2016 and the year-earlier period, with $1.31 billion of the increase over the fourth quarter and year-earlier periods attributable to the Merchants acquisition. Average public fund deposits for the third quarter increased $7.3 million, or 0.7%, from the fourth quarter of 2016 and $111.5 million, or 12.4%, from the third quarter of 2016. The Merchants acquisition was responsible for the addition of $63.5 million of public fund deposits. Public fund deposits as a percentage of total deposits decreased from 12.9% in the third quarter of 2016 to 11.8% in the third quarter of 2017.

Borrowings
The third quarter of 2017 ended with external borrowings of $126.4 million, including subordinated debt held by unconsolidated subsidiary trusts and other long-term debt, which were $122.0 million, or 49.1%, lower than external borrowings at December 31, 2016 and $109.7 million, or 46.5%, below the end of the third quarter of 2016. The Merchants acquisition was responsible for $24.2 million of the increase from December 31, 2016, with $20.6 million in subordinated debt held by unconsolidated subsidiary trusts and $3.6 million in other long-term debt assumed as part of the transaction.
Securities sold under agreement to repurchase, which represent collateralized municipal and commercial customer accounts that price and operate similar to a deposit instrument, were $310.7 million at the end of the third quarter of 2017, with $278.1 million in such securities acquired in the Merchants transaction.

Table of Contents
Shareholders’ Equity
Total shareholders’ equity of $1.59 billion at the end of the third quarter represents an increase of $395.2 million from the balance at December 31, 2016. This increase consisted of $78.5 million related to stock issued in connection with the NRS acquisition, $262.3 million related to stock issued in connection with the Merchants acquisition, net income of $78.7 million, an $8.3 million increase in other comprehensive income, $7.9 million from treasury stock issued to the Company’s benefit plans, $3.7 million from shares issued under the employee stock plan and $4.0 million from employee stock options earned, partially offset by dividends declared of $48.2 million. The change in other comprehensive income was comprised of a $6.8 million increase in the after-tax market value adjustment on the available-for-sale investment portfolio and a positive $1.5 million adjustment to the funded status of the Company’s retirement plans. Over the past 12 months, total shareholders’ equity increased by $352.7 million, as net income and the issuance of common stock in association with the NRS and Merchants acquisitions, the employee stock plan and the Company’s benefit plans, more than offset a lower market value adjustment on investments, dividends declared and the change in the funded status of the Company’s defined benefit pension and other postretirement plans.
The Company’s Tier 1 leverage ratio, a primary measure of regulatory capital for which 5% is the requirement to be “well-capitalized”, was 9.54% at the end of the third quarter, down 1.01% from year-end 2016 and 81 basis points below its level one year earlier. The decrease in the Tier 1 leverage ratio in comparison to December 31, 2016 was the result of ending shareholders’ equity, excluding intangibles and other comprehensive income items, increasing 11.9%, primarily from net earnings retention and the issuance of shares in connection with the Merchants and NRS acquisitions, while average assets, excluding intangibles and the market value adjustment on investments, increased 23.7%, primarily due to the Merchants and NRS acquisitions. The Tier 1 leverage ratio decreased as compared to the prior year’s third quarter as shareholders’ equity, excluding intangibles and other comprehensive income, increased 14.2% due to strong earnings retention and the issuance of shares in connection with the Merchants and NRS acquisitions, while average assets excluding intangibles and the market value adjustment, increased 23.9%, driven mostly by the Merchants and NRS acquisitions. The net tangible equity-to-assets ratio (a non-GAAP measure) of 8.36% decreased 0.88% from December 31, 2016 and decreased 1.30% versus September 30, 2016 (See Table 11 for Reconciliation of Quarterly GAAP to Non-GAAP Measures). The decrease in the tangible equity ratio over the past 12 months was due to a proportionally larger increase in tangible asset levels than the increase in tangible equity due primarily to the impact of intangibles resulting from the Merchants and NRS transactions and the decrease in the investment market value adjustment.
The dividend payout ratio (dividends declared divided by net income) for the first nine months of 2017 was 61.3%, compared to 53.6% for the nine months ended September 30, 2016. Dividends declared increased 16.2% as the Company’s quarterly dividend per share was raised from$0.31 to $0.32 in August 2016 and from $0.32 to $0.34 in August 2017, while net income for September YTD 2017, impacted by one-time costs incurred in association with the Merchants and NRS acquisitions, increased 1.6% over the prior year period. The 2017 dividend increase marked the Company’s 25th consecutive year of increased dividend payouts to common shareholders. Additionally, the number of common shares outstanding increased 14.0% over the last twelve months including the impact of the 4.68 million shares issued in the Merchants transaction that accounted for 10.6% of the total increase and the 1.32 million shares issued in the NRS transaction that accounted for 3.0% of the total increase.
Liquidity
Liquidity risk is a measure of the Company’s ability to raise cash when needed at a reasonable cost and minimize any loss. The Bank maintains appropriate liquidity levels in both normal operating environments as well as stressed environments. The Company must be capable of meeting all obligations to its customers at any time and, therefore, the active management of its liquidity position remains an important management objective. The Bank has appointed the Asset Liability Committee (“ALCO”) to manage liquidity risk using policy guidelines and limits on indicators of potential liquidity risk. The indicators are monitored using a scorecard with three risk level limits. These risk indicators measure core liquidity and funding needs, capital at risk and change in available funding sources. The risk indicators are monitored using such statistics as the core basic surplus ratio, unencumbered securities to average assets, free loan collateral to average assets, loans to deposits, deposits to total funding and borrowings to total funding ratios.
Given the uncertain nature of our customers' demands as well as the Company's desire to take advantage of earnings enhancement opportunities, the Company must have adequate sources of on- and off-balance sheet funds available that can be acquired in time of need. Accordingly, in addition to the liquidity provided by balance sheet cash flows, liquidity must be supplemented with additional sources such as credit lines from correspondent banks and borrowings from the FHLB and the Federal Reserve Bank of New York (“Federal Reserve”). Other funding alternatives may also be appropriate from time to time, including wholesale and retail repurchase agreements, large certificates of deposit and the brokered CD market. The primary source of non-deposit funds is FHLB overnight advances, of which there were no outstanding borrowings at September 30, 2017.
The Bank’s primary sources of liquidity are its liquid assets, as well as unencumbered securities that can be used to collateralize additional funding. At September 30, 2017, the Bank had $241.5 million of cash and cash equivalents of which $35.7 million are interest-earning deposits held at the Federal Reserve, FHLB and other correspondent banks. The Bank also had $1.7 billion in unused FHLB borrowing capacity based on the Company’s quarter-end collateral levels. Additionally, the Company has $1.3 billion of unencumbered securities that could be pledged at the FHLB or Federal Reserve to obtain additional funding. There is $25 million available in unsecured lines of credit with other correspondent banks.

The Company’s primary approach to measuring short-term liquidity is known as the Basic Surplus/Deficit model. It is used to calculate liquidity over two time periods: first, the amount of cash that could be made available within 30 days (calculated as liquid assets less short-term liabilities as a percentage of average assets); and second, a projection of subsequent cash availability over an additional 60 days. As of September 30, 2017, this ratio was 11.4% for 30-days and 11.3% for 90-days, excluding the Company's capacity to borrow additional funds from the FHLB and other sources. There is a sufficient amount of liquidity based on the Company’s internal policy requirement of 7.5%.
A sources and uses statement is used by the Company to measure intermediate liquidity risk over the next twelve months. As of September 30, 2017, there is more than enough liquidity available during the next year to cover projected cash outflows. In addition, stress tests on the cash flows are performed in various scenarios ranging from high probability events with a low impact on the liquidity position to low probability events with a high impact on the liquidity position. The results of the stress tests as of September 30, 2017 indicate the Bank has sufficient sources of funds for the next year in all simulated stressed scenarios.
To measure longer-term liquidity, a baseline projection of loan and deposit growth for five years is made to reflect how liquidity levels could change over time. This five-year measure reflects ample liquidity for loan and other asset growth over the next five years.
Though remote, the possibility of a funding crisis exists at all financial institutions. Accordingly, management has addressed this issue by formulating a Liquidity Contingency Plan, which has been reviewed and approved by both the Company’s Board of Directors (the “Board”) and the Company’s ALCO. The plan addresses the actions that the Company would take in response to both a short-term and long-term funding crisis.
A short-term funding crisis would most likely result from a shock to the financial system, either internal or external, which disrupts orderly short-term funding operations. Such a crisis would likely be temporary in nature and would not involve a change in credit ratings. A long-term funding crisis would most likely be the result of drastic credit deterioration at the Company. Management believes that both potential circumstances have been fully addressed through detailed action plans and the establishment of trigger points for monitoring such events.

Item 3. | Quantitative and Qualitative Disclosures about Market Risk

Market risk is the risk of loss in a financial instrument arising from adverse changes in market rates, prices or credit risk. Credit risk associated with the Company's loan portfolio has been previously discussed in the asset quality section of the MD&A. Management believes that the tax risk of the Company's municipal investments associated with potential future changes in statutory, judicial and regulatory actions is minimal. Treasury, agency, mortgage-backed and CMO securities issued by government agencies comprise 83% of the total portfolio and are currently rated AAA by Moody’s Investor Services and AA+ by Standard & Poor’s. Municipal and corporate bonds account for 17% of the total portfolio, of which, 98% carry a minimum rating of A-. The remaining 2% of the portfolio is comprised of other investment grade securities. The Company does not have material foreign currency exchange rate risk exposure. Therefore, almost all the market risk in the investment portfolio is related to interest rates.
The ongoing monitoring and management of both interest rate risk and liquidity, in the short and long term time horizons is an important component of the Company's asset/liability management process, which is governed by limits established in the policies reviewed and approved annually by the Company’s Board. The Board delegates responsibility for carrying out the policies to the ALCO, which meets each month. The committee is made up of the Company's senior management as well as regional and line-of-business managers who oversee specific earning asset classes and various funding sources. As the Company does not believe it is possible to reliably predict future interest rate movements, it has maintained an appropriate process and set of measurement tools, which enables it to identify and quantify sources of interest rate risk in varying rate environments. The primary tool used by the Company in managing interest rate risk is income simulation.
While a wide variety of strategic balance sheet and treasury yield curve scenarios are tested on an ongoing basis, the following reflects the Company's projected net interest income sensitivity over the subsequent twelve months based on:

· | Asset and liability levels using September 30, 2017 as a starting point.

· | There are assumed to be conservative levels of balance sheet growth, low-to-mid single digit growth in loans and deposits, while using the cash flows from investment contractual maturities and prepayments to repay short-term capital market borrowings or reinvest into securities or cash equivalents.

· | The prime rate and federal funds rates are assumed to move up over a 12-month period while moving the long end of the treasury curve to spreads over the three month treasury that are more consistent with historical norms (normalized yield curve). In the -100 basis point model, the prime and federal funds rates move lower over a 12-month period while moving the long end of the curve to levels over the three month treasury using spreads at a time when the yield curve was flat. Deposit rates are assumed to move in a manner that reflects the historical relationship between deposit rate movement and changes in the federal funds rate.

49

Table of Contents

· | Cash flows are based on contractual maturity, optionality, and amortization schedules along with applicable prepayments derived from internal historical data and external sources.

Net Interest Income Sensitivity Model

Change in interest rates | Calculated annualized increase (decrease) in projected net interest income at September 30, 2017
+200 basis points | ($3,540,000)
+100 basis points | ($1,266,000)
-100 basis points | ($4,163,000)

The modeled net interest income (“NII”) decreases in rising rate environments from the flat rate scenario. The decrease is largely a result of assumed deposit and funding costs increasing faster than the repricing of corresponding assets. In the short term (year one), the assumed increase of deposit rates in the rising rate environment temporarily outweighs the benefit of earning asset yields increasing to higher levels. However, over a longer time period (years two and beyond), the growth in NII improves in the rising rate environments as lower yielding assets mature and are replaced at higher rates.
In the falling rate environment scenario, the Bank shows interest rate risk exposure to lower short term rates and also a flatter yield curve. Net interest income declines during the first twelve months largely due to lower assumed rates on adjustable and variable rate assets. Corresponding deposit rates are assumed to remain constant.
The analysis does not represent a Company forecast and should not be relied upon as being indicative of expected operating results. These hypothetical estimates are based upon numerous assumptions: the nature and timing of interest rate levels (including yield curve shape), prepayments on loans and securities, deposit decay rates, pricing decisions on loans and deposits, reinvestment/replacement of asset and liability cash flows, and other factors. While the assumptions are developed based upon current economic and local market conditions, the Company cannot make any assurances as to the predictive nature of these assumptions, including how customer preferences or competitor influences might change. Furthermore, the sensitivity analysis does not reflect actions that the ALCO might take in responding to or anticipating changes in interest rates.

Item 4. | Controls and Procedures

Evaluation of Disclosure Controls and Procedures
The Company maintains disclosure controls and procedures, as defined in Rule 13a -15(e) and 15d – 15(e) under the Securities Exchange Act of 1934 as amended (the “Exchange Act”), designed to ensure information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is: (i) recorded, processed, summarized, and reported within the time periods specified in the SEC rules and forms, and (ii) accumulated and communicated to management, including the principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure. Based on management’s evaluation of the effectiveness of the Company’s disclosure controls and procedures, with the participation of the Chief Executive Officer and the Chief Financial Officer, it has concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, these disclosure controls and procedures were effective as of September 30, 2017.
Changes in Internal Control over Financial Reporting
The Company regularly assesses the adequacy of its internal controls over financial reporting. There have been no changes in the Company’s internal controls over financial reporting in connection with the evaluation referenced in the paragraph above that occurred during the Company’s quarter ended September 30, 2017 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Part II. | Other Information

Item 1. | Legal Proceedings

The Company and its subsidiaries are subject in the normal course of business to various pending and threatened legal proceedings in which claims for monetary damages are asserted. As of September 30, 2017, management, after consultation with legal counsel, does not anticipate that the aggregate ultimate liability arising out of litigation pending or threatened against the Company or its subsidiaries will be material to the Company’s consolidated financial position. On at least a quarterly basis, the Company assesses its liabilities and contingencies in connection with such legal proceedings. For those matters where it is probable that the Company will incur losses and the amounts of the losses can be reasonably estimated, the Company records an expense and corresponding liability in its consolidated financial statements. To the extent the pending or threatened litigation could result in exposure in excess of that liability, the amount of such excess is not currently estimable. The range of reasonably possible losses for matters where an exposure is not currently estimable or considered probable, beyond the existing recorded liabilities, is between $0 and $1 million in the aggregate. Although the Company does not believe that the outcome of pending litigation will be material to the Company’s consolidated financial position, it cannot rule out the possibility that such outcomes will be material to the consolidated results of operations for a particular reporting period in the future.
