SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The accompanying consolidated financial statements include the accounts of Merchants Bancshares, Inc. (the “Company”), and its wholly-owned subsidiary Merchants Bank (the “Bank,” and collectively with the Company, “Merchants”, “we,” “us,” or “our”). All material intercompany accounts and transactions are eliminated in consolidation. We offer a full range of deposit, loan, cash management, and trust services to meet the financial needs of individual consumers, businesses and municipalities at 31 full-service banking offices throughout the state of Vermont and one full-service banking office in Massachusetts as of December 31, 2016. Management’s Use of Estimates in Preparation of Financial Statements The preparation of financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income and expenses during the reporting periods. The most significant estimates include those used in determining the allowance for credit losses, income taxes, interest income recognition on loans and investments and analysis of other-than-temporary impairment of our investment securities portfolio. Operating results in the future may vary from the amounts derived from Management's estimates and assumptions. Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand, amounts due from banks, Federal Funds sold and other short-term investments, with maturities at time of purchase of less than 90 days, in the accompanying consolidated statements of cash flows. Investment Securities We classify certain of our investments in debt securities as held to maturity, which are carried at amortized cost, if we have the positive intent and ability to hold such securities to maturity. Investments in debt securities that are not classified as held to maturity and equity securities that have readily determinable fair values are classified as available for sale securities or trading securities. Available for sale securities are investments not classified as trading or held to maturity. Available for sale securities are carried at fair value which is measured at each reporting date. The resulting unrealized gain or loss is reflected in accumulated other comprehensive income (loss) net of the associated tax effects. Gains and losses on sales of investment securities are recognized through the statement of income using the specific identification method. Transfers from securities available for sale to securities held to maturity are recorded at the securities’ fair values on the date of the transfer. Any net unrealized gains or losses continue to be included as a separate component of accumulated other comprehensive income (loss), on a net of tax basis. As long as the securities are carried in the held to maturity portfolio, such amounts are amortized (accreted) over the estimated remaining life of the transferred securities as an adjustment to yield in a manner consistent with the amortization of premiums and discounts. Interest and dividend income, including amortization of premiums and discounts, are recorded in earnings for all categories of investment securities. Discounts and premiums related to debt securities are amortized using the level-yield method which anticipates prepayments for amortizing securities. Management evaluates securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) OTTI related to credit loss, which must be recognized in the income statement and (2) other-than-temporary impairment (OTTI) related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings. Federal Home Loan Bank System We are a member of the Federal Home Loan Bank System, which consists of 12 regional Federal Home Loan Banks. The Federal Home Loan Bank (“FHLB”) of Boston provides a central credit facility primarily for member institutions. Member institutions are required to acquire and hold shares of capital stock in the FHLB in an amount at least equal to the sum of 0.35% of the aggregate principal amount of its unpaid residential mortgage loans and similar obligations at the beginning of each year. We were in compliance with this requirement at December 31, 2016. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. Bank Owned Life Insurance We purchased life insurance policies on certain key executives where the Bank is the beneficiary. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value (“CSV”) adjusted for other charges or other amounts due that are probable at settlement. Increases in the CSV of the policies, as well as death benefits received, net of any CSV, are recorded in noninterest income, and are not subject to income taxes. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of deferred loan fees and costs, and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Allowance for Loan Losses (“ALL”) The ALL is based on Management’s estimate of the amount required to reflect probable incurred credit losses in the loan portfolio. Factors considered in evaluating the adequacy of the ALL include previous loss experience, the size and composition of the portfolio, risk rating composition, current economic and real estate market conditions and their effect on the borrowers, the performance of individual loans in relation to contractual terms and estimated fair values of properties that secure impaired loans. The ALL consists of specific and general components. The specific component relates to loans that are individually classified as impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings (“TDR”) and classified as impaired. Commercial and commercial real estate loans are individually evaluated for impairment when a loan meets any of the specific criteria identified in our methodology. If a loan is impaired, the loan is either charged down, or a portion of the ALL is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Large groups of smaller balance homogeneous loans, such as consumer and residential real estate loans are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered TDRs. Concessions that result in a loan being considered a TDR usually consists of a reduction in interest rate to a below market rate, taking into account the credit quality of the note, or a deferment or reduction of payments, principal or interest, which alters the Bank’s position or significantly extends the note’s maturity date, such that the present value of cash flows to be received is less than those contractually established at the loan’s origination. TDRs are measured at the present value of estimated future cash flows using the loans effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, we determine the amount of reserve in accordance with the accounting policy for the allowance for loan losses. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The general component covers non-impaired loans and loans collectively evaluated for impairment and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by us over the most recent 5 years. This actual loss experiences is supplemented with other factors based on the risks present for each portfolio segment. These factors include consideration of the following: 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; 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. Due to the added risks associated with loans which are graded as pass-watch, special mention, and substandard that are not classified as impaired, an additional analysis is performed to determine whether an allowance is needed that is not fully captured by the historical loss experience. While historical loss experience by loan segment and migration of loans into higher risk classifications are considered, the following factors are also considered in determining the level of needed allowance on such loans: the historical loss rates of loans specifically classified as pass-watch, special mention, or substandard; and the trends in the collateral on the loans included within these classifications. This analysis created an additional $108 thousand at December 31, 2016 compared to $543 thousand at December 31, 2015 in needed allowance for loan losses. We have divided the loan portfolio into portfolio segments, each with different risk characteristics and methodologies for assessing risk. Each portfolio segment is broken down into class segments where appropriate. Class segments contain unique measurement attributes, risk characteristics and methods for monitoring and assessing risk that are necessary to develop the allowance for loan and lease losses. Unique characteristics such as borrower type, loan type, collateral type, and risk characteristics define each class segment. Descriptions of the segments are as follows: Commercial, financial and agricultural: We offer a variety of loan options to meet the specific needs of commercial customers including term loans and lines of credit. Such loans are made available to businesses for working capital such as inventory and receivables, business expansion and equipment purchases. Generally, a collateral lien is placed on equipment, receivables, inventory or other assets owned by the borrower. These loans carry a higher risk than commercial real estate loans by the nature of the underlying collateral, and the collateral value may change daily. To reduce the risk, management generally employs enhanced monitoring requirements, obtains personal guarantees and, where appropriate, may also attempt to secure real estate as collateral. Municipal: Municipal loans primarily consist of term and time loans issued on a tax-exempt and taxable basis which are general obligations of the municipality. These loans are viewed as lower risk as municipalities can utilize taxing power to meet financial obligations. Real Estate – Residential: Residential real estate loans consist primarily of loans secured by first or second mortgages on primary residences. We originate adjustable-rate and fixed-rate, one- to four-family residential real estate loans for the construction, purchase or refinancing of a mortgage. These loans are generally collateralized by owner-occupied properties located in our market area. Loans on one- to four-family residential real estate are generally originated in amounts of no more than 80% of the purchase price or appraised value (whichever is lower). Hazard insurance is required. Mortgage title insurance is also required for all first mortgages and for second mortgages in excess of $100,000. Real Estate – Commercial: We offer commercial real estate loans to finance real estate purchases and refinancing of existing commercial properties. These commercial real estate loans are generally secured by first liens on the real estate, which may include both owner occupied and non-owner occupied facilities. The types of facilities financed include apartments, hotels, warehouses, retail facilities, manufacturing facilities and office buildings. Our underwriting analysis includes credit verification, independent appraisals, a review of the borrower's financial condition, and a detailed analysis of the borrower’s underlying cash flows. Real Estate – Construction: We offer construction loans for the construction, expansion and improvement of residential and commercial properties which are secured by the real estate being developed. A review of all plans and budgets is performed prior to approval, third party progress documents are required during construction, and an independent approval process for all draw and release requests is maintained to ensure that funding is prudently administered and that funds are sufficient to complete the project. Installment: We offer traditional direct consumer installment loans for various personal needs, including vehicle and boat financing. The vast majority of these loans are secured by a lien on the purchased vehicle and are underwritten using credit scores and income verification. We do not provide any indirect consumer lending activities. Income Recognition on Impaired and Nonaccrual Loans Interest income on mortgage and commercial loans is discontinued and placed on non-accrual status at the time the loan is 91 days delinquent unless the loan is well-secured and in process of collection. Mortgage loans, and commercial loans are charged off to the extent principal or interest is deemed uncollectible. Installment loans continue to accrue interest until they are charged off no later than 120 days past due unless the loan is well secured and are in the process of collection. Past-due status is based on the contractual terms of the loan. In all cases, loans are placed on non-accrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Non-accrual loans and loans past due 91 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. All interest accrued but not received for loans placed on non-accrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Under the cash-basis method, interest income is recorded when the payment is received in cash. Loans may be returned to accrual status when there is a sustained period of repayment performance (generally a minimum of six months) by the borrower, in accordance with the contractual terms of the loans and all principal and interest amounts contractually due, including arrearages, are reasonably assured of repayment within an acceptable period of time. While a loan is classified as nonaccrual and the future collectability of the recorded loan balance is uncertain, any payments received are generally applied to reduce the principal balance. When the future collectability of the recorded loan balance is expected, interest income may be recognized on a cash basis. In the case where a nonaccrual loan had been partially charged-off, recognition of interest on a cash basis is limited to that which would have been recognized on the recorded loan balance at the contractual interest rate. Interest collections in excess of that amount are recorded as a reduction of principal. Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are provided using straight-line and accelerated methods at rates that depreciate the original cost of the premises and equipment over the shorter of their estimated useful lives or the expected lease term in the case of leasehold improvements. Expenditures for maintenance, repairs and renewals of minor items are generally charged to expense as incurred. When premises and equipment are replaced, retired, or deemed no longer useful they are written down to estimated selling price less costs to sell by a charge to current earnings. Investments in Real Estate Limited Partnerships We have investments in various real estate limited partnerships that acquire, develop, own and operate low and moderate-income housing. Our ownership interest in these limited partnerships ranges from 5.36% to 99.9% as of December 31, 2016. These investments are made directly in Low Income Housing Tax Credit, or LIHTC, partnerships formed by third parties. As a limited partner in these operating partnerships, we receive tax credits and tax deductions for losses incurred by the underlying properties. Effective January 1, 2014, the Company adopted Accounting Standards Update (“ASU”) 2014-01, “Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects.” The amendment permits an entity to amortize the initial cost of the investment in proportion to the amount of the tax credits and other tax benefits received and recognize the net investment performance in the income statement as a component of income tax expense. Merchants has unfunded commitments of $3.68 million at year-end related to qualified affordable housing project investments, which will be fulfilled in 2018. There were no impairment losses during the year resulting from the forfeiture or ineligibility of tax credits related to qualified affordable housing project investments. Goodwill and Other Acquisition-Related Intangible Assets An acquirer in a business combination is required, upon initially obtaining control of another entity, to recognize the assets, liabilities and any non-controlling interest in the acquiree at fair value as of the acquisition date. Contingent consideration, if any, is also recognized and measured at fair value on the date of acquisition. In addition, the accounting standards for business combinations require that: (i) acquisition-related transaction costs be expensed as incurred; (ii) specific requirements be met in order to accrue for a restructuring plan as part of the acquisition; (iii) certain pre-acquisition contingencies be recognized at fair value; and (iv) acquired loans be recorded at fair value as of the acquisition date without recognition of an allowance for loan losses. Goodwill is recognized in an amount equal to the excess of the purchase price over the fair value of the assets acquired and liabilities assumed. “Acquisition-related intangible assets” are separately identified and recognized, where appropriate, for assets such as trade names and the estimated values of acquired core deposits and/or customer relationships. The remaining intangible asset is recognized as goodwill. Goodwill and indefinite-lived intangible assets are not amortized but, rather, are reviewed for impairment at least annually, with impairment losses recognized as a charge to expense when they occur. Acquisition-related intangible assets other than goodwill and indefinite-lived intangible assets are amortized to expense over their estimated useful lives and are periodically reviewed by management to assess recoverability, with impairment losses recognized as a charge to expense if carrying amounts exceed fair values. Goodwill is evaluated for impairment at the reporting unit level. The impairment evaluation is performed as of an annual date or more frequently if a triggering event indicates that impairment may have occurred. Entities have the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, based on this qualitative assessment, an entity determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then the two-step impairment test is not required. The first step (Step 1) of the two-step impairment test is used to identify potential impairment, and involves comparing each reporting unit’s estimated fair value to its carrying amount, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill is not deemed to be impaired. The second step involves calculating the implied fair value of goodwill for each reporting unit for which impairment was indicated in Step 1. The implied fair value of goodwill is determined in a manner similar to how the amount is determined in a business acquisition. If the implied fair value of the goodwill exceeds the carrying amount of goodwill assigned to the reporting unit, no impairment exists. Other intangibles consist of core deposit intangible assets, which are amortized on an accelerated method over its estimated useful life of 10 years. Other Real Estate Owned Collateral acquired through foreclosure is initially recorded at the lower of cost or fair value, less estimated costs to sell, at the time of acquisition, establishing a new cost basis. Any cost in excess of the estimated fair value on the transfer date is charged to the allowance for credit losses. Subsequent decreases in the fair value of other real estate owned (“OREO”) are reflected as a write-down and charged to expense. Net operating income or expense related to foreclosed property is included in noninterest expense in the accompanying consolidated statements of income. Repurchase Agreements Repurchase agreements are accounted for as secured financing transactions since we maintain effective control over the transferred securities and the transfer meets the other criteria for such accounting. Obligations to repurchase securities sold are reflected as a liability in the consolidated balance sheets. The securities underlying the agreements are delivered to a custodial account for the benefit of the repurchase agreement holders. The repurchase agreement holders, who may sell, loan or otherwise dispose of such securities to other parties in the normal course of their operations, agree to resell to us the same securities at the maturities of the agreements. Stock-Based Compensation The Amended and Restated Merchants Bancshares, Inc. 2008 Stock Incentive Plan provides grants of up to 600,000 stock options or restricted stock awards to certain key employees. We recognize compensation expense for services received in a share-based payment transaction over the required service period, generally defined as the vesting period. The compensation cost is based on the grant-date fair value of the award (as determined by quoted market prices). Stock awards are granted at fair market value on the date of the grant and typically vest based on a three year service period. Due to the pending merger with Community Bank System, Inc., Merchants accelerated the vesting date for the 2014, 2015 and 2016 grant years for select individuals. The fair value of an option grant is estimated on the grant date using the Black-Scholes option-pricing model that requires us to develop estimates for assumptions used in the model. The Black-Scholes valuation model uses the following assumptions: expected volatility, expected term of option, risk-free interest rate and dividend yield. Expected volatility estimates are developed by us based on historical volatility of our stock. We use historical data to estimate the expected term of the options. The risk-free interest rate for periods within the expected life of the option is based on the U.S. Treasury yield in effect at the grant date. Employee Benefit Costs Prior to 1995, we maintained a non-contributory pension plan covering substantially all employees that met eligibility requirements. The plan was curtailed in 1995. The cost of this plan, based on actuarial computations of current and future benefits, is charged to current operating expenses. We recognize the overfunded or underfunded status of a single employer defined benefit post retirement plan as an asset or liability on the consolidated balance sheets and recognize changes in the funded status in comprehensive income in the year in which the change occurred. Income Taxes Deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Low-income housing tax credits and historic rehabilitation credits are recognized as a reduction of income tax expense in the year in which they are earned. We recognize interest and/or penalties related to income tax matters in other noninterest expense in our consolidated statements of income. Penalties and/or interest were zero or immaterial for 2016, 2015 and 2014. Our policy is to reduce deferred tax assets by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. Earnings Per Share Basic earnings per share are calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding. Diluted earnings per share are computed in a manner similar to that of basic earnings per share except that the weighted average number of common shares outstanding is increased to include the number of additional common shares that would have been outstanding if all potentially dilutive common shares (such as stock options) were issued during the period, computed using the treasury stock method. Shares held in rabbi trusts related to deferred compensation plans are considered outstanding for purposes of computing earnings per share. Comprehensive Income Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available for sale, unrealized gains and losses on cash flow hedges and changes in the funded status of the pension plan, which are also recognized as separate components of equity. Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are such matters that will have a material effect on the financial statements. Restrictions on Cash Cash on hand or on deposit with the Federal Reserve Bank was required to meet regulatory reserve and clearing requirements. Derivative Financial Instruments and Hedging Activities At the inception of a derivative contract, we designate the derivative as one of three types based on our intentions and belief as to likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item, are recognized in current earnings as fair values change. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. For both types of hedges, changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as noninterest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. We formally document the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. We also formally assess, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued, but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings |
