Summary of significant accounti

Summary of significant accounting policies	12 Months Ended

Summary of significant accounting policies	NOTE 1. Summary of significant accounting policies: Nature of operations Use of estimates in the preparation of financial statements Principles of consolidation NHTB Capital Trust II and NHTB Capital Trust III, affiliates of the Company, were formed to sell capital securities to the public through a third party trust pool. In accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 810-10, “Consolidation—Overall,” these subsidiaries have not been included in the consolidated financial statements. Cash and cash equivalents Securities available-for-sale Declines in marketable equity securities below their cost that are deemed other than temporary are reflected in earnings as realized losses. For any debt security with a fair value less than its amortized cost basis, the Company will determine whether it has the intent to sell the debt security or whether it is more likely than not it will be required to sell the debt security before the recovery of its amortized cost basis. If either condition is met, the Company will recognize a full impairment charge to earnings. For all other debt securities that are considered other-than-temporarily impaired and do not meet either condition, the credit loss portion of impairment will be recognized in earnings as realized losses. The other-than-temporary impairment related to all other factors will be recorded in other comprehensive income. Federal Home Loan Bank stock Investment in CHC The Bank used the equity method of accounting to account for its 50% ownership investment in CHC through September 3, 2013. An investor using the equity method initially records an investment at cost. Subsequently, the carrying amount of the investment is increased to reflect the investor’s share of income of the investee and is reduced to reflect the investor’s share of losses of the investee or dividends received from the investee. The investor’s share of the income or losses of the investee is included in the investor’s net income as the investee reports them. Adjustments similar to those made in preparing consolidated financial statements, such as elimination of intercompany gains and losses, also are applicable to the equity method. Loans held-for-sale . Nonaccrual loans Acquired loans— Under the accounting model for acquired loans, the excess of cash flows expected to be collected over the carrying amount of the loans, referred to as the “accretable yield,” is accreted into interest income over the lives of the loans using the effective yield method. The difference between contractually required principal and interest payments and the cash flows expected to be collected, referred to as the “nonaccretable difference,” includes estimates of both the impact of prepayments and future credit losses expected to be incurred over the life of the loan. As such, charge-offs on acquired loans are first applied to the nonaccretable difference and then to any allowance for loan losses recognized subsequent to acquisition. Actual cash collections are monitored relative to management’s expectations and revised cash flow forecasts are prepared, as warranted. These revised forecasts involve updates, as necessary, of the key assumptions and estimates used in the initial estimate of fair value. Generally speaking, expected cash flows are affected by: • Changes in the expected principal and interest payments over the estimated life • Changes in prepayment assumptions • Changes in interest rate indices for variable rate loans Allowance for loan losses— The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. General component— The qualitative factors are determined based on the various risk characteristics of each loan segment. Risk characteristics relevant to each portfolio segment are as follows: Residential real estate: The Bank generally does not originate loans with a loan-to-value ratio greater than 80 percent and does not grant subprime loans. All loans in this segment are collateralized by owner-occupied residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Home equity loans: Loans in this segment are primarily second to residential real estate loans held by the Bank and the same loan-to-value ratio is generally required as with residential real estate loans. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Commercial real estate – owner occupied: Loans in this segment are primarily income-producing properties that are owner occupied and are located throughout New Hampshire and Vermont. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy as evidenced by increased vacancy rates which, in turn, will have an effect on the credit quality in this segment. Management periodically obtains rent rolls and continually monitors the cash flows of these loans. Commercial real estate – non-owner occupied: Loans in this segment are primarily income-producing properties that are non-owner occupied and located throughout New Hampshire and Vermont. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy as evidenced by increased vacancy rates which, in turn, will have an effect on the credit quality in this segment. Management periodically obtains rent rolls and continually monitors the cash flows of these loans. Construction loans: The Bank offers construction loan financing on one-to-four family owner occupied dwellings in the Bank’s local real estate market. Generally, the Bank makes construction loans up to 80% of value with terms of up to nine months. During the construction phase, inspections are made to assess construction progress and monitor the disbursement of loan proceeds. The Bank also offers a “one-step” construction loan, which provides construction and permanent financing with one loan closing. The “one-step” is provided under the same terms and conditions of the Bank’s conventional residential program. Commercial and municipal loans: Loans in this segment are made to businesses and are generally secured by assets of the business. Repayment is expected from the cash flows of the business. A weakened economy, and resultant decreased consumer spending, will have an effect on the credit quality in this segment. Consumer loans: Loans in this segment are unsecured or secured by collateral such as automobiles, boats and other recreational vehicles. Repayment is dependent on the credit quality of the individual borrower. Credit card loans: Loans in this segment are unsecured and approvals are based primarily upon debt to income ratios and the borrower’s credit score. Repayment is dependent on the credit quality of the individual borrower. Allocated component A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. 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 a 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. Impairment is measured on a loan by loan basis for commercial and municipal, commercial real estate and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. The Company periodically may agree to modify the contractual terms of loans. When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a troubled debt restructuring (“TDR”). All TDRs are initially classified as impaired. Unallocated component— Deferred loan origination fees/costs Loan servicing Mortgage servicing rights are amortized in proportion to, and over the period of, estimated net servicing revenues. Refinance activities are considered in estimating the period’s net servicing revenues. Impairment of mortgage servicing rights is assessed based on the fair value of those rights. Fair values are estimated using discounted cash flows based on a current market interest rate. For purposes of measuring impairment, the rights are stratified based on the interest rate risk characteristics of the underlying loans. The amount of impairment recognized is the amount by which the capitalized mortgage servicing rights for a stratum exceed their fair value. Concentration of credit risk Premises and equipment Investment in real estate Real estate owned and property acquired in settlement of loans Earnings per share Advertising Income taxes Goodwill and other intangibles The Company evaluates goodwill and other intangibles on an annual basis or whenever there is an indicator of impairment. Any impairment losses are charged to earnings. The Company amortizes other intangible assets over their respective estimated useful lives. The Company has estimated the remaining useful life of its insurance agency customer list intangible, trust company customer list intangible, and core deposit intangible assets to have a weighted-average of fifteen years, fifteen years, and ten years, respectively. Intangible assets are stated at cost less accumulated amortization.

Specifically, the amendments: (1) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities; (2) eliminate the presumption that a general partner should consolidate a limited partnership; (3) affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and (4) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. ASU 2015-02 is effective for interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In April 2015, FASB issued ASU 2015-03, “Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The amendments in this ASU require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs is not affected by the amendments in this ASU. The standard is effective for interim and annual reporting periods beginning after December 15, 2015, with early adoption permitted. The guidance should be applied on a retrospective basis. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In April 2015, FASB issued ASU 2015-05, “Intangibles – Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” This ASU provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. ASU 2015-05 is effective for interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In August 2015, FASB issued ASU 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments.” This ASU requires the acquirer in a business combination to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments in the Update require the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. ASU 2015-16 is effective for interim and annual reporting periods beginning after December 15, 2015. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In January 2016, FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities.” The amendments in this update make targeted improvements to GAAP as follows: 1. Require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. 2. Simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. 3. Eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities. 4. Eliminate the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. 5. Require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 6. Require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. 7. Require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. 8. Clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The standard is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption of item 6 above is permitted for financial statements of fiscal years or interim periods that have not yet been issued. Early adoption of other items above is not permitted. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In February 2016, FASB issued ASU 2016-02, “Leases (Topic 842).” This ASU was issued to increase transparency and comparability among organizations by requiring reporting entities to recognize all leases, including operating, as lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The amendments in this ASU are effective for public entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements.

Debentures III are the sole assets of Trust III. The Company used the proceeds to redeem the securities issued by NHTB Capital Trust I, a wholly owned subsidiary of the Company, which were callable on September 30, 2004. Total expenses associated with the offering of $99 thousand and $104 thousand are included in other assets as of December 31, 2015 and 2014, respectively, and are being amortized on a straight-line basis over the life of Debentures III.

The Company has fully and unconditionally guaranteed all of the obligations of the Trust. The guaranty covers the quarterly distributions and payments on liquidation or redemption of Capital Securities III, but only to the extent that the Trust has funds necessary to make these payments. Capital Securities III are mandatorily redeemable upon the maturing of Debentures III on March 30, 2034 or upon earlier redemption as provided in the Indenture. The Company has the right to redeem Debentures III, in whole or in part, at the liquidation amount plus any accrued but unpaid interest to the redemption date.

The Company may, at its option, beginning with the interest payment date of November 1, 2019, and on any interest payment date thereafter, redeem the Notes, in whole or in part, at par plus accrued and unpaid interest to the date of redemption. Any partial redemption will be made pro rata among all of the noteholders. The Notes are not subject to repayment at the option of the noteholders. The Notes will be unsecured, subordinated obligations of the Company and will rank junior in right of payment to the Company’s senior indebtedness and to the Company’s obligations to its general creditors.

The unrealized losses on 9 equity securities have occurred for less than 12 months and the Company does not feel the losses relate to credit quality of the issuers. The Company has the ability and intent to hold these investments until a recovery of cost basis.

Loans rated 40: Loans in this category are considered “special mention.” These loans are starting to show signs of potential weakness and are being closely monitored by management. Loans rated 50: Loans in this category are considered “substandard.” Generally, a loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. There is a distinct possibility that the Company will sustain some loss if the weakness is not corrected. Loans rated 60: Loans in this category are considered “doubtful.” Loans classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable. Loans rated 70: Loans in this category are considered uncollectible (“loss”) and of such little value that their continuance as loans is not warranted. On an annual basis, or more often if needed, the Company formally reviews the ratings on all commercial real estate, construction and commercial and municipal loans over $250 thousand. For residential real estate and consumer loans, the Company initially assesses credit quality based upon the borrower’s ability to pay and subsequently monitors these loans based on the borrower’s payment activity. Loan Servicing Rights In addition to total loans previously shown, the Company services loans for other financial institutions. Participation loans are loans originated by the Company for a group of banks. Sold loans are loans originated by the Company and sold to the secondary market. The Company services these loans and remits the payments received to the buyer. The Company specifically originates long-term, fixed-rate loans to sell.

Derivative Instruments and Hedging Activities	NOTE 11. Derivative Instruments and Hedging Activities The Company’s mortgage banking activities include interest rate lock commitments (“IRLCs”) and forward sales commitments that result in derivative financial instruments. IRLCs are provided on applications for residential mortgages intended for resale and are accounted for as non-hedging derivatives. The Company arranges offsetting forward sales commitments for these rate-locks, which are designated as economic hedges. The IRLCs generally terminate once the loan is funded, the lock period expires or the borrower decides not to contract for the loan. The forward commitments generally terminate once the loan is sold, the commitment period expires or the borrower decides not to contract for the loan. The following table summarizes the fair values of derivative financial instruments in the consolidated balance sheet as of December 31, 2015. There were no IRLCs and forward sale commitments recorded at December 31, 2014.

Employee benefit plans	NOTE 13. Employee benefit plans: Defined Benefit Pension Plan The Company has a defined benefit pension plan covering substantially all full-time employees who have attained age 21 and have completed one year of service. Annual contributions to the plan are based on actuarial estimates. In December 2006, the Company elected to suspend the plan so that employees no longer earn additional benefits for future service under this plan. The following tables set forth information about the plan for the years ended December 31, 2015, 2014 and 2013: (Dollars in thousands) 2015 2014 2013 Change in projected benefit obligation: Benefit obligation at beginning of year $ 8,974 $ 6,961 $ 7,507 Interest cost 373 341 332 Actuarial (gain) loss (349 ) 2,069 (648 ) Benefits paid (248 ) (247 ) (220 ) Settlements (167 ) (150 ) (10 ) Benefit obligation at end of year 8,583 8,974 6,961 Change in plan assets: Plan assets at estimated fair value at beginning of year 8,179 8,186 7,361 Actual return on plan assets (132 ) 390 1,055 Benefits paid (248 ) (247 ) (220 ) Settlements (167 ) (150 ) (10 ) Fair value of plan assets at end of year 7,632 8,179 8,186 Funded status $ (951 ) $ (795 ) $ 1,225 Amounts recognized in accumulated other comprehensive loss, before tax effect, consist of unrecognized net actuarial losses of $5.0 million for the years ending December 31, 2015 and December 31, 2014. The discount rate and rate of increase in future compensation levels used in determining the actuarial present value of the projected benefit obligation were 4.40% and 0%, respectively, at December 31, 2015, 4.24% and 0%, respectively, at December 31, 2014, and 5.00% and 0%, respectively, at December 31, 2013. The accumulated benefit obligation for the defined benefit pension plan was $8.6 million and $9.0 million at December 31, 2015 and 2014, respectively. Components of net periodic pension cost (benefit) and other comprehensive loss (income) for the years ended December 31: (Dollars in thousands) 2015 2014 2013 Interest cost on benefit obligation $ 373 $ 341 $ 332 Expected return on assets (640 ) (646 ) (579 ) Amortization of unrecognized actuarial loss 355 173 303 Net periodic pension cost (benefit) 88 (132 ) 56 Other changes in plan assets and benefit obligations recognized as other comprehensive loss (income), before tax effect: Actuarial loss (gain) 423 2,325 (1,124 ) Amortization of unrecognized actuarial loss (355 ) (173 ) (303 ) Total recognized as other comprehensive loss (income) 68 2,152 (1,427 ) Total recognized as net periodic pension cost (benefit) and other comprehensive loss (income) $ 156 $ 2,020 $ (1,371 ) The estimated net loss that will be amortized from accumulated other comprehensive loss into net periodic pension cost over the year ended December 31, 2016 is $384 thousand. For the years ended December 31, 2015, 2014 and 2013, the assumptions used to determine the net period pension cost are as follows: 2015 2014 2013 Discount rate 4.24 % 5.00 % 4.50 % Increase in future compensation levels — — — Expected long-term rate of return on plan assets 8.00 8.00 8.00 The Company has examined the historical benchmarks for returns in each asset class in its portfolio, and based on the target asset mix has developed a weighted-average expected return for the portfolio as a whole, partly taking into consideration forecasts of long-term expected inflation rates of 2.5%. The long-term rate of return used by the Company is 8.0%. This rate was determined by adding the expected inflation rates to the weighted sum of the expected long-term return on each asset allocation. Plan Assets The Company’s pension plan assets measured at fair value at December 31, 2015, by asset category, are as follows: Fair Value Measurements at Reporting Date Using: Asset Category Total Quoted Prices in Significant Significant (Dollars in thousands) December 31, 2015: U.S. equity securities $ 732 $ 425 $ 307 $ — Registered investment companies (a) 6,783 6,783 — — Money market 117 117 — — Totals $ 7,632 $ 7,325 $ 307 $ — (a) Includes 59% invested in fixed income funds and 41% invested in equity and index funds. The Company’s pension plan assets measured at fair value at December 31, 2014, by asset category, are as follows: Fair Value Measurements at Reporting Date Using: Asset Category Total Quoted Prices in Significant Significant (Dollars in thousands) December 31, 2014: U.S. equity securities $ 868 $ 473 $ 395 $ — Registered investment companies (a) 7,271 7,271 — — Money market 40 40 — — Totals $ 8,179 $ 7,784 $ 395 $ — (a) Includes 52% invested in fixed income funds and 48% invested in equity and index funds. The Company’s pension plan assets are generally classified within level 1 or level 2 of the fair value hierarchy (See Note 15, “Fair Value Measurements,” to the Consolidated Financial Statements for a description of the fair value hierarchy) because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. Equity securities include 30,294 shares of the Company’s common stock as of December 31, 2015 and 2014. The fair values of the shares on those dates were $425 thousand (5.6% of total plan assets) and $473 thousand (5.8% of total plan assets), respectively. The investment policy for the defined benefit pension plan sponsored by the Company is based on ERISA standards for prudent investing. The Company seeks maximum return, while limiting risk, through a balanced portfolio of equity and fixed income investments. The investment objectives also include appreciation of principal with a modest requirement for current income. The investment horizon varies with circumstances. Within each asset class, a diversified mix of individual securities and bonds is selected. To maximize the ability of achieving the Company’s overall goals for the plan’s assets and to provide the required level of income each year, the allocation between common stocks, bonds and cash equivalents shall adhere to the following target allocation based on market value: Target Allocation Equities 38-58 % Fixed income 42-62 % The Company expects to contribute $2.3 million to the defined benefit pension plan in 2016. Estimated future benefit payments, which reflect expected future service, as appropriate, are as follows: (Dollars in thousands) 2016 $ 341 2017 366 2018 384 2019 405 2020 435 Years 2021-2025 2,316 Defined Contribution Plans The Bank sponsors a Profit Sharing—Stock Ownership Plan for employees of the Bank and McCrillis & Eldredge. The Bank may elect, but is not required, to make discretionary and/or matching contributions to the Plan. Effective January 1, 2008, the Bank amended the Profit Sharing—Stock Ownership Plan whereby employees will receive a safe harbor, non-elective contribution equal to 3% of eligible compensation for the plan year, as defined in the plan. In addition, the Bank shall make a matching contribution in an amount equal to employees’ elective deferrals up to a percentage of compensation for the plan year, to be determined annually, not to exceed 4%. Finally, the Bank may make an additional profit sharing contribution, determined annually, to be allocated on a pro rata basis to eligible employees based on their compensation in relation to the compensation of all participants. CTC sponsors a Charter Trust Company Profit Sharing Plan for employees of CTC. CTC may elect, but is not required, to make discretionary and/or matching contributions to the CTC Plan. The CTC Plan allows employees to make qualified retirement plan (pre-tax) contributions as well as Roth (after tax) contributions. Employees will receive a safe harbor, non-elective contribution equal to 3% of eligible compensation for the plan year, as defined in the CTC Plan. In addition, CTC may make an elective matching contribution in an amount to be determined by CTC on an annual basis and discretionary matching contributions will be made on both pre-tax and Roth contributions. Employee and safe harbor contributions are vested 100% immediately. Employer discretionary match contributions are vested 20% for each year of service and become 100% vested at five years of service. For 2015, 2014, and 2013, there were no discretionary employer matching contributions. For 2015, 2014, and 2013, participating employees in both plans had contributions totaling $1.3 million, $1.3 million and $954 thousand, respectively. The Company made contributions totaling $932 thousand for 2015, $929 thousand for 2014 and $802 thousand for 2013 for both plans. A participant’s retirement benefit will depend on the amount of the contributions to the Plans together with the gains or losses on the investments. Other Plans and Employment Agreements The Company has entered into salary continuation agreements for supplemental retirement income with certain executives and senior officers. The total liability for these agreements included in other liabilities was $5.1 million and $4.8 million for the years ended December 31, 2015 and 2014, respectively. Expense recorded under these agreements was $744 thousand, $939 thousand and $690 thousand in 2015, 2014 and 2013, respectively. A total of $209 thousand was paid to retired executives and one active employee in 2015 per the agreements, $166 thousand was paid to retired executives and one active employee in 2014 and $219 thousand was paid to retired executives and one active employee in 2013. Effective as of June 1, 2012, the Company and the Bank each entered into an employment agreement (“the Agreement”) with the President and Chief Executive Officer of the Company and the Bank (the “Executive”). The Agreements have an initial term of three years and will automatically extend annually for one year unless either the Company, Bank or the President gives contrary written notice in advance. The Agreements provide for a guaranteed minimum salary and certain benefits. In the event of voluntary termination without cause or voluntary termination with good reason, the Executive is entitled to receive a severance benefit equal to a lump sum payment equal to salary and bonus which the executive would have received had he continued to work for the remaining unexpired term, and certain other benefits per the Agreement. Upon a Change in Control, as defined in the Agreement, the Executive will receive the severance benefits described above with such benefits being calculated as if the remaining unexpired term of the agreement was three years. The Company and the Bank has a three-year change in control agreement with the Chief Operating Officer in which the officer will receive a lump sum severance payment equal to three year’s annual base salary in effect as of the date of termination. The Company also has one-year change of control agreements with the Chief Financial Officer and five other officers in which the officer will receive a lump sum severance payment equal to one year’s annual base salary in effect as of the date of termination. On October 7, 2011, the Bank entered into parallel employment agreements with the Chief Executive Officer and the Chief Financial Officer of MEI. The employment agreements are for a period of three years, and extend automatically for three additional three year renewal periods unless either the Company or the executive give contrary written notice in advance. The employment agreements provide for a guaranteed minimum salary, performance bonus and certain benefits. The employment agreements also provide for severance benefits upon termination without cause, or following a change in control, in amounts of and/or for the remaining unexpired employment period as defined in the employment agreement. In 2008, the Company adopted ASC 715, “Compensation—Retirement Benefits,” and recognized a liability for the Company’s future postretirement benefit obligations under endorsement split-dollar life insurance arrangements. The total liability for the arrangements included in other liabilities was $528 thousand at December 31, 2015 and $457 thousand at December 31, 2014. The Company recorded expense under this arrangement of $71 thousand in 2015, $93 thousand in 2014 and $14 thousand in 2013.

Fair value measurements

Fair value measurements	12 Months Ended
	Dec. 31, 2015
Fair value measurements	NOTE 15. Fair value measurements: ASC 820-10, “Fair Value Measurement—Overall,” provides a framework for measuring fair value under generally accepted accounting principles. This guidance also allows an entity the irrevocable option to elect fair value for the initial and subsequent measurement for certain financial assets and liabilities on a contract-by-contract basis. In accordance with ASC 820-10, the Company groups its financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1—Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange. Level 1 also includes U.S. Treasury, other U.S. Government and agency mortgage-backed securities that are traded by dealers or brokers in active markets. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2—Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained from third party pricing services for identical or comparable assets or liabilities. Level 3—Valuations for assets and liabilities that are derived from other methodologies, including option pricing models, discounted cash flow models and similar techniques, are not based on market exchange, dealer, or broker traded transactions. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets and liabilities. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Company’s financial assets and financial liabilities carried at fair value for December 31, 2015 and 2014. The Company did not have any significant transfers of assets between level 1 and level 2 of the fair value hierarchy during the year ended December 31, 2015. The Company’s investments in marketable equity securities are generally classified within level 1 or level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The Company’s investment in mortgage-backed securities, asset-backed securities, and other debt securities available-for-sale are generally classified within level 2 of the fair value hierarchy. For these securities, the Company obtains fair value measurements from independent pricing services. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. treasury yield curve, trading levels, market consensus prepayment speeds, credit information and the instrument’s terms and conditions. The Company enters into interest rate lock commitments for residential mortgage loans intended for sale, which commit the Company to lend funds to a potential borrower at a specific interest rate and within a specified period of time. The estimated fair value of commitments to originate residential mortgage loans for sale is based on quoted prices for similar loans in active markets. However, this value is adjusted by a factor which considers the likelihood that the loan in a lock position will ultimately close. The closing ratio is derived from the Company’s internal data and is adjusted using significant management judgment which is not observable. As such, interest rate lock commitments are classified as Level 3 measurements. The Company utilizes forward sale commitments as economic hedges against potential changes in the values of the interest rate lock commitments and loans held for sale. The fair values of the Company’s mandatory delivery loan sale commitments are determined similarly to the IRLCs using quoted prices in the market place that are observable and adjusted for inputs which are not observable, as discussed above. As such, best efforts and mandatory delivery forward sale commitments are classified as Level 3 measurements. Level 3 is for positions that are not traded in active markets or are subject to transfer restrictions, valuations are adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate is used. Subsequent to inception, management only changes level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying investment or comparable entities, subsequent rounds of financing, recapitalization and other transactions across the capital structure, offerings in the equity or debt markets, and changes in financial ratios or cash flows. The Company’s impaired loans are reported at the fair value of the underlying collateral less costs to sell if repayment is expected solely from the collateral. Collateral values are estimated using level 2 inputs based upon appraisals of similar properties obtained from a third party. For level 3 inputs, fair value is based upon management estimates of the value of the underlying collateral or the present value of the expected cash flows. Other real estate owned values are estimated using level 2 inputs based upon appraisals of similar properties obtained from a third party. For level 3 inputs, fair values are based on management estimates. The following summarizes assets measured at fair value on a recurring basis as of December 31, 2015 and 2014.

Acquisitions

Acquisitions	NOTE 16. Acquisitions: On September 4, 2013, the Bank acquired the remaining 50% of CHC that was not previously owned by the Company for $6.2 million in cash. The Bank was one of the six original owners of CHC and now, as a result of this acquisition, is the sole owner of CHC and its subsidiaries. Goodwill recognized amounted to $4.6 million and of that total, none is deductible for tax purposes. A remeasurement gain of $1.4 million was recorded in noninterest income based on the fair value of the Company’s equity interest in CHC immediately before the business combination. The acquisition date fair value of the Company’s equity interest in CHC was based on independent third party valuations of CHC as a whole obtained by the buyer and the seller and the agreed-upon arm’s length purchase price of fifty percent of CHC from another financial institution. The agreed-upon purchase price of $6.2 million was based on the third party valuations. The carrying value of the equity investment prior to acquisition was $4.8 million resulting in the remeasurement gain of $1.4 million to reflect the value of $6.2 million for 50% ownership at acquisition. CTC, a subsidiary of CHC, was formed in 1984 as a New Hampshire-chartered non-depository trust company and is regulated by the State of New Hampshire Banking Department. Headquartered in Concord, New Hampshire, CTC also has offices in New London, Meredith, Peterborough, Hanover and Rochester. CTC’s team of professional wealth advisors and investment managers work confidentially with individuals and families to create, manage and preserve wealth. Managing over $1.5 billion in client assets, CTC acts as fiduciaries for clients in 43 states and 10 countries. For the Bank, full ownership of CTC marks an important milestone in the Bank’s plan to provide a fully comprehensive one-stop financial services company. As part of this plan, the Bank also acquired a New Hampshire-based independent insurance agency, MEI, in 2011. With these strategic acquisitions, the Bank can now offer financial leadership, products and services to customers at any stage of life. On October 25, 2013, the Company acquired a 100% ownership interest in Central Financial Corporation. Costs to acquire consisted of 1,087,416 shares issued with a market value of $14.70 per share for a total acquisition cost of $16 million. Goodwill recognized amounted to $4.6 million and of that total, none is deductible for tax purposes. The Company acquired Central Financial Corporation to solidify its presence in Vermont, doubling the number of banking offices with the single acquisition to serve present and future customers. A summary of the fair values of assets acquired and liabilities assumed at the date of the acquisitions is as follows: (Dollars in thousands) Central Financial Charter Holding Cash and due from banks $ 17,512 $ 3,095 Interest-bearing time deposits with other banks 1,992 — Federal Home Loan Bank stock 467 — Securities available-for-sale 6,494 633 Loans, net 127,721 — Other real estate owned 1,477 — Premises and equipment 2,532 1,365 Other assets and accrued interest receivable 1,669 1,411 Total assets acquired 159,864 6,504 Total deposits 149,684 — Securities sold under agreements to repurchase 2,602 — Accrued expenses and other liabilities 791 2,706 Total liabilities assumed 153,077 2,706 Net assets acquired 6,787 3,798 Goodwill 4,630 4,566 Core deposit intangible asset 4,568 — Customer list intangible asset — 4,036 Total purchase price $ 15,985 $ 12,400 The results of operations of the acquired entities have been included in the Company’s consolidated financial statements since the respective acquisition dates.

Stockholders' equity

Stockholders' equity	12 Months Ended

Stockholders' equity	NOTE 17. Stockholders’ equity: Liquidation account—On May 22, 1986, the Lake Sunapee Bank, FSB received approval from the FHLB and converted from a federally chartered mutual savings bank to a federally chartered stock savings bank. At the time of conversion, the Bank established a liquidation account in an amount of $4.3 million (equal to the Bank’s net worth as of the date of the latest financial statement included in the final offering circular used in connection with the conversion). The liquidation account will be maintained for the benefit of eligible account holders who maintain their deposit accounts in the Bank after conversion. In the event of a complete liquidation of the Bank subsequent to conversion (and only in such event), each eligible account holder will be entitled to receive a liquidation distribution from the liquidation account before any liquidation distribution may be made with respect to capital stock. The amount of the liquidation account is reduced to the extent that the balances of eligible deposit accounts are reduced on any year-end closing date subsequent to the conversion. Company management believes the balance in the liquidation account would be immaterial to the consolidated financial statements as of December 31, 2015. Dividends—The Bank may not declare or pay a cash dividend on or purchase any of its stock if the effect would be to reduce the net worth of the Bank below either the amount of the liquidation account or the net worth requirements of the banking regulators. Special bad debts deduction—In prior years, the Bank was allowed a special tax-basis bad debt deduction under certain provisions of the Internal Revenue Code. As a result, retained income of the Bank, as of December 31, 2015, includes $2.1 million for which federal and state income taxes have not been provided. If the Bank no longer qualifies as a bank as defined in certain provisions of the Internal Revenue Code, this amount will be subject to recapture in taxable income ratably over four (4) years, subject to a combined federal and state tax rate of approximately 40%.

Earnings per share (EPS)

Earnings per share (EPS)	NOTE 18. Earnings per share (EPS): The Company computes earnings per share in accordance with FASB ASC 260-10. Under the guidance, unvested restricted stock awards that contain non-forfeitable rights to dividends or dividend equivalents are participating securities and, therefore, are included in computing basic EPS pursuant to the two-class method. The two-class method determines earnings per share for each class of common stock and participating securities according to dividends or dividend equivalents and their respective participation rights in undistributed earnings. Basic EPS has been computed using the weighted average number of common shares outstanding during each period. Diluted EPS assumes, as of the beginning of the period, exercise of stock awards using the treasury stock method. Certain of our stock awards that would potentially dilute Basic EPS in the future were antidilutive for years ending December 31, 2015 and 2014 and are discussed below. The following is a reconciliation of the numerators and denominators used in the calculation of Basic and Diluted EPS for the years ending December 31, 2015 and 2014: (Dollars in thousands, except for per share data): Income Shares Per-Share Year ended December 31, 2015 Basic EPS Net income as reported $ 9,029 Cumulative preferred stock dividend earned (74 ) Dividends and undistributed earnings allocated to participating shares (77 ) Net income applicable to common stock 8,878 8,245,233 $ 1.08 Effect of dilutive equity-based awards — 10,593 Diluted EPS Income available to common stockholders and assumed conversions $ 8,878 8,255,826 $ 1.08 Year ended December 31, 2014 Basic EPS Net income as reported $ 10,040 Cumulative preferred stock dividend earned (230 ) Net income available to common stockholders 9,810 8,235,213 $ 1.19 Effect of dilutive securities, options — 11,315 Diluted EPS Income available to common stockholders and assumed conversions $ 9,810 8,246,528 $ 1.19 Year ended December 31, 2013 Basic EPS Net income as reported $ 8,414 Cumulative preferred stock dividend earned (316 ) Net income available to common stockholders 8,098 7,294,916 $ 1.11 Effect of dilutive securities, options — 6,945 Diluted EPS Income available to common stockholders and assumed conversions $ 8,098 7,301,861 $ 1.11

Other comprehensive loss

Other comprehensive loss	NOTE 19. Other comprehensive loss: Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities are reported as a separate component of the equity section of the consolidated balance sheets, such items, along with net income, are components of comprehensive income. The components of other comprehensive loss included in stockholders’ equity are as follows during the years ended December 31: (Dollars in thousands) 2015 2014 2013 Net unrealized holding (losses) gains on available-for-sale securities $ (430 ) $ 2,367 $ (2,979 ) Reclassification adjustment for realized gains in net income (347 ) (950 ) (964 ) Other comprehensive (loss) income before income tax effect (777 ) 1,417 (3,943 ) Income tax benefit (expense) 308 (560 ) 1,561 (469 ) 857 (2,382 ) Other comprehensive (loss) income—pension plan (See Note 13) (68 ) (2,152 ) 1,427 Income tax benefit (expense) 26 853 (567 ) (42 ) (1,299 ) 860 Change in fair value of derivatives used for cash flow hedges — — 166 Income tax expense — — (65 ) — — 101 Other comprehensive income—equity investment — — 12 Reclassification adjustment for realized gains in net income — — (44 ) Other comprehensive loss before income tax effect — — (32 ) Income tax benefit (expense) — — — — — (32 ) Other comprehensive loss, net of tax effect $ (511 ) $ (442 ) $ (1,453 ) Accumulated other comprehensive loss consists of the following as of December 31: (Dollars in thousands) 2015 2014 Net unrealized holding losses on available-for-sale securities, net of taxes $ (810 ) $ (341 ) Unrecognized net actuarial loss, defined benefit pension plan, net of tax (3,040 ) (2,998 ) Accumulated other comprehensive loss $ (3,850 ) $ (3,339 ) Realized gains and losses on securities are identified on the consolidated statements of income as net gain on sales and calls of securities. Amortization of unrecognized actuarial losses related to the Company’s pension plan was reported on the consolidated statements of income within salaries and employee benefits. Gains from the former equity investment in CHC were reported on the consolidated statements of income within remeasurement gain of equity interest in CHC. The tax effect of these realized gains and losses, if any, are included in provision for income taxes, and the after tax amount is included in the net income.

Regulatory matters

Regulatory matters	12 Months Ended
	Dec. 31, 2015
Regulatory matters	NOTE 20. Regulatory matters: The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by the agencies that, if undertaken, could have a direct material effect on the Company’s and the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s and the Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Effective January 1, 2015 (with a phase-in period of two to four years for certain components), the Company and the Bank became subject to new capital regulations adopted by the FRB and the OCC, which implement the Basel III regulatory capital reforms and the changes required by the Dodd-Frank Act. The new regulations require a new common equity Tier 1 (“CET1”) capital ratio of 4.5%, increase the minimum Tier 1 capital to risk-weighted assets ratio to 6.0% from 4.0%, require a minimum total capital to risk-weighted assets ratio of 8.0% and require a minimum Tier 1 leverage ratio of 4.0%. CET1 generally consists of common stock and retained earnings, subject to applicable adjustments and deductions. Under new prompt corrective action regulations, in order to be considered “well capitalized,” the Bank must maintain a CET1 capital ratio of 6.5% (new) and a Tier 1 ratio of 8.0% (increased from 6.0%), a total risk based capital ratio of 10.0% (unchanged) and a Tier 1 leverage ratio of 5.0% (unchanged). In addition, the regulations establish a capital conservation buffer above the required capital ratios that phased in beginning January 1, 2016 at 0.625% of risk-weighted assets and increases each year by 0.625% until it is fully phased in at 2.5% effective January 1, 2019. Beginning January 1, 2016, failure to maintain the capital conservation buffer will limit the ability of the Company and the Bank to pay dividends, repurchase shares or pay discretionary bonuses to executive officers and similar employees. The new regulations implemented changes to what constitutes regulatory capital. Certain instruments will no longer constitute qualifying capital, subject to phase-out periods. In addition, Tier 2 capital is no longer limited to the amount of Tier 1 capital included in total capital. Mortgage servicing rights, certain deferred tax assets and investments in unconsolidated subsidiaries over designated percentages of CET1 will be deducted from capital. The Company and the Bank have elected to permanently opt out of the inclusion of accumulated other comprehensive income in capital calculations, as permitted by the regulations. This opt-out will reduce the impact of market volatility on our regulatory capital ratios. The new regulations also changed the risk weights of certain assets, including an increase in the risk weight of certain high volatility commercial real estate acquisition, development and construction loans and non-residential mortgage loans that are 90 days past due or on non-accrual status to 150% from 100%, a credit conversion factor for the unused portion of commitments with maturities of less than one year that are not cancellable to 20% from 0%, an increase in the risk weight for mortgage servicing and deferred tax assets that are not deducted from capital to 250% from 100%, and an increase in the risk weight for equity exposures to 600% from 0%. As of December 31, 2015, the Company and the Bank met each of their capital requirements and the most recent notification from the OCC categorized the Bank as “well-capitalized.” There are no conditions or events since that notification that management believes have changed the Bank’s category. The Company’s and the Bank’s actual capital amounts and ratios are presented in the table below as of December 31, : Actual For Capital To Be Well (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio As of December 31, 2015: Lake Sunapee Bank Group: Tier 1 Leverage Capital $ 117,270 8.03 % $ 58,380 4.0 % N/A N/A Tier 1 Risk-Based Capital 117,270 11.34 62,029 6.0 N/A N/A Total Risk-Based Capital 126,352 12.22 82,705 8.0 N/A N/A Common Equity Tier 1 Capital 97,270 9.41 46,521 4.5 N/A N/A Lake Sunapee Bank, fsb: Tier 1 Leverage Capital $ 131,586 9.02 % $ 58,346 4.0 % $ 72,933 5.0 % Tier 1 Risk-Based Capital 131,586 12.74 61,976 6.0 82,635 8.0 Total Risk-Based Capital 140,668 13.62 82,635 8.0 103,294 10.0 Common Equity Tier 1 Capital 131,586 12.74 46,482 4.5 67,141 6.5 Actual For Capital To Be Well (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio As of December 31, 2014: Lake Sunapee Bank, fsb: Total Capital to Risk Weighted Assets $ 131,597 13.28 % $ 79,283 8.0 % $ 99,103 10.0 % Tier 1 Capital to Risk Weighted Assets 122,161 12.33 39,641 4.0 59,462 6.0 Tier 1 Capital to Total Assets 122,161 8.43 57,937 4.0 72,421 5.0 The following is a reconcilement of the Bank’s total equity, included in the consolidated balance sheet, to the regulatory capital ratios disclosed in the table above: December 31, 2015 December 31, 2014 (Dollars in thousands) Tier 1 Total Tier 1 Total Total stockholders’ equity $ 170,936 $ 170,936 $ 172,730 $ 172,730 Accumulated other comprehensive loss 3,850 3,850 3,339 3,339 Allowable allowance for loan losses — 9,064 — 9,436 Goodwill and intangible assets (43,200 ) (43,200 ) (53,908 ) (53,908 ) Unrealized gains on equity exposures — 18 — — Totals $ 131,586 $ 140,668 $ 122,161 $ 131,597

Preferred stock

Preferred stock	12 Months Ended
	Dec. 31, 2015
Preferred stock	NOTE 21. Preferred stock: On August 25, 2011, as part of the Small Business Lending Fund (“SBLF”), the Company entered into a Purchase Agreement with the U.S. Department of the Treasury (“Treasury”) pursuant to which the Company issued and sold to the Treasury 20,000 shares of the Company’s Non-Cumulative Perpetual Preferred Stock, Series B, par value $0.01 per preferred share, having a liquidation preference of $1,000 per preferred share (the “Series B Preferred Stock”). As part of the acquisition of The Nashua Bank, on December 21, 2012, the Company assumed The Nashua Bank’s outstanding 3,000 shares of Senior Non-Cumulative Perpetual Preferred Stock, Series A (the “TNB Preferred Stock”) issued to Treasury under the SBLF program. The Company’s initial dividend rate payable on SBLF capital is, at most, five percent, and the dividend rate falls to one percent if a bank’s small business lending increases by ten percent or more. Banks that increase their lending by less than ten percent but more than 2.5 percent pay rates between two percent and four percent. If a bank’s lending does not increase in the first two years, however, the rate increases to seven percent, and after 4.5 years total, the rate increases to nine percent regardless of the amount of small business lending activities. The dividend will be paid only when declared by the Company’s Board of Directors. The Series B Preferred Stock has no maturity date and ranks senior to the Common Stock with respect to the payment of dividends and distributions and amounts payable upon liquidation, dissolution and winding up of the Company. The Series B Preferred Stock generally is non-voting, other than class voting on certain matters that could adversely affect the Series B Preferred Stock. The SBLF Preferred Stock may be redeemed at any time by the Company, subject to the approval of its federal banking regulator. The redemption price is the aggregate liquidation preference of the SBLF Preferred Stock plus accrued but unpaid dividends and pro rata portion of any lending incentive fee. All redemptions must be in an amount at least equal to 25% of the number of originally issued shares of SBLF Preferred Stock, or 100% of the then-outstanding shares if less than 25% of the number of shares originally issued. On December 29, 2014, the Company redeemed $15.0 million of the outstanding preferred securities issued under the U.S. Treasury’s SBLF program. The redemption was funded with the proceeds of the $17.0 million private placement of subordinated notes, which the Company completed in October 2014, as described in Note 2. At December 31, 2014, $8.0 million of preferred securities were outstanding under the SBLF program. On December 3, 2015, the Company redeemed the remaining $8.0 million of the outstanding preferred securities issued under the U.S. Treasury’s SBLF program. The redemption was funded from a dividend from the Bank to the Company.

Financial instruments

Financial instruments	12 Months Ended

Financial instruments	NOTE 22. Financial instruments: The Company is 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 include commitments to originate loans, standby letters of credit and unadvanced funds on loans. The instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheets. The contract amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for loan commitments and standby letters of credit is represented by the contractual amounts of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Commitments to originate loans are agreements to lend to a customer provided there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include secured interests in mortgages, accounts receivable, inventory, property, plant and equipment and income-producing properties. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance by a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. As of December 31, 2015 and 2014, the maximum potential amount of the Company’s obligation was $1.1 million for financial and standby letters of credit. The Company’s outstanding letters of credit generally have a term of less than one year. If a letter of credit is drawn upon, the Company may seek recourse through the customer’s underlying line of credit. If the customer’s line of credit is also in default, the Company may take possession of the collateral, if any, securing the line of credit. Notional amounts of financial liabilities with off-balance sheet credit risk are as follows as of December 31: (Dollars in thousands) 2015 2014 Commitments to extend credit $ 27,421 $ 25,503 Letters of credit $ 1,074 $ 1,146 Lines of credit $ 109,127 $ 119,901 Unadvanced portion of construction loans $ 6,358 $ 12,560

Operating Segments	NOTE 24. Operating Segments: The Company has two reportable operating segments: Banking, which includes the activities of the Bank and its subsidiaries, excluding CHC, and Wealth Management, which includes the activities of CHC and its subsidiaries. Lake Sunapee Bank Group operates as the parent company of the Bank and its subsidiaries and all financial activity between them is eliminated. The accounting policies of each reportable segment are the same as those of the Company. Income tax expense for the individual segments is calculated based on the activity of the segments. CHC was acquired on September 4, 2013 and did not meet the requirements for disclosure of a reportable segment for the year ended December 31, 2013. A summary of the Company’s operating segments is as follows: (Dollars in thousands) Banking Wealth Holding Eliminations Total Year Ended December 31, 2015 Net interest and dividend income (expense) $ 43,094 $ 17 $ (1,847 ) $ — $ 41,264 Provision for loan losses 1,056 — — — 1,056 Non-interest income 10,686 8,449 10,715 (11,226 ) 18,624 Non-interest expense 38,284 7,017 904 — 46,205 Income before provision for income taxes 14,440 1,449 7,964 (11,226 ) 12,627 Provision (benefit) for income taxes 4,126 537 (1,065 ) — 3,598 Net income $ 10,314 $ 912 $ 9,029 $ (11,226 ) $ 9,029 Total Assets $ 1,518,244 $ 22,858 $ 174,789 $ (197,370 ) $ 1,518,521 (Dollars in thousands) Banking Wealth Holding Eliminations Total Year Ended December 31, 2014 Net interest and dividend income (expense) $ 42,757 $ 7 $ (835 ) $ — $ 41,929 Provision for loan losses 905 — — — 905 Non-interest income 10,810 8,416 6,993 (6,993 ) 19,226 Non-interest expense 38,865 7,035 746 — 46,646 Income before provision for income taxes 13,797 1,388 5,412 (6,993 ) 13,604 Provision (benefit) for income taxes 3,704 488 (628 ) — 3,564 Net income $ 10,093 $ 900 $ 6,040 $ (6,993 ) $ 10,040 Total Assets $ 1,480,357 $ 18,325 $ 177,837 $ (172,733 ) $ 1,503,786

Principles of consolidation	Principles of consolidation NHTB Capital Trust II and NHTB Capital Trust III, affiliates of the Company, were formed to sell capital securities to the public through a third party trust pool. In accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 810-10, “Consolidation—Overall,” these subsidiaries have not been included in the consolidated financial statements.
Cash and cash equivalents	Cash and cash equivalents
Securities available-for-sale	Securities available-for-sale Declines in marketable equity securities below their cost that are deemed other than temporary are reflected in earnings as realized losses. For any debt security with a fair value less than its amortized cost basis, the Company will determine whether it has the intent to sell the debt security or whether it is more likely than not it will be required to sell the debt security before the recovery of its amortized cost basis. If either condition is met, the Company will recognize a full impairment charge to earnings. For all other debt securities that are considered other-than-temporarily impaired and do not meet either condition, the credit loss portion of impairment will be recognized in earnings as realized losses. The other-than-temporary impairment related to all other factors will be recorded in other comprehensive income.
Federal Home Loan Bank stock	Federal Home Loan Bank stock
Investment in CHC	Investment in CHC The Bank used the equity method of accounting to account for its 50% ownership investment in CHC through September 3, 2013. An investor using the equity method initially records an investment at cost. Subsequently, the carrying amount of the investment is increased to reflect the investor’s share of income of the investee and is reduced to reflect the investor’s share of losses of the investee or dividends received from the investee. The investor’s share of the income or losses of the investee is included in the investor’s net income as the investee reports them. Adjustments similar to those made in preparing consolidated financial statements, such as elimination of intercompany gains and losses, also are applicable to the equity method.
Loans held-for-sale	Loans held-for-sale .
Nonaccrual loans	Nonaccrual loans
Acquired loans	Acquired loans— Under the accounting model for acquired loans, the excess of cash flows expected to be collected over the carrying amount of the loans, referred to as the “accretable yield,” is accreted into interest income over the lives of the loans using the effective yield method. The difference between contractually required principal and interest payments and the cash flows expected to be collected, referred to as the “nonaccretable difference,” includes estimates of both the impact of prepayments and future credit losses expected to be incurred over the life of the loan. As such, charge-offs on acquired loans are first applied to the nonaccretable difference and then to any allowance for loan losses recognized subsequent to acquisition. Actual cash collections are monitored relative to management’s expectations and revised cash flow forecasts are prepared, as warranted. These revised forecasts involve updates, as necessary, of the key assumptions and estimates used in the initial estimate of fair value. Generally speaking, expected cash flows are affected by: • Changes in the expected principal and interest payments over the estimated life • Changes in prepayment assumptions • Changes in interest rate indices for variable rate loans
Allowance for loan losses	Allowance for loan losses— The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. General component— The qualitative factors are determined based on the various risk characteristics of each loan segment. Risk characteristics relevant to each portfolio segment are as follows: Residential real estate: The Bank generally does not originate loans with a loan-to-value ratio greater than 80 percent and does not grant subprime loans. All loans in this segment are collateralized by owner-occupied residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Home equity loans: Loans in this segment are primarily second to residential real estate loans held by the Bank and the same loan-to-value ratio is generally required as with residential real estate loans. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Commercial real estate – owner occupied: Loans in this segment are primarily income-producing properties that are owner occupied and are located throughout New Hampshire and Vermont. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy as evidenced by increased vacancy rates which, in turn, will have an effect on the credit quality in this segment. Management periodically obtains rent rolls and continually monitors the cash flows of these loans. Commercial real estate – non-owner occupied: Loans in this segment are primarily income-producing properties that are non-owner occupied and located throughout New Hampshire and Vermont. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy as evidenced by increased vacancy rates which, in turn, will have an effect on the credit quality in this segment. Management periodically obtains rent rolls and continually monitors the cash flows of these loans. Construction loans: The Bank offers construction loan financing on one-to-four family owner occupied dwellings in the Bank’s local real estate market. Generally, the Bank makes construction loans up to 80% of value with terms of up to nine months. During the construction phase, inspections are made to assess construction progress and monitor the disbursement of loan proceeds. The Bank also offers a “one-step” construction loan, which provides construction and permanent financing with one loan closing. The “one-step” is provided under the same terms and conditions of the Bank’s conventional residential program. Commercial and municipal loans: Loans in this segment are made to businesses and are generally secured by assets of the business. Repayment is expected from the cash flows of the business. A weakened economy, and resultant decreased consumer spending, will have an effect on the credit quality in this segment. Consumer loans: Loans in this segment are unsecured or secured by collateral such as automobiles, boats and other recreational vehicles. Repayment is dependent on the credit quality of the individual borrower. Credit card loans: Loans in this segment are unsecured and approvals are based primarily upon debt to income ratios and the borrower’s credit score. Repayment is dependent on the credit quality of the individual borrower. Allocated component A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. 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 a 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. Impairment is measured on a loan by loan basis for commercial and municipal, commercial real estate and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. The Company periodically may agree to modify the contractual terms of loans. When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a troubled debt restructuring (“TDR”). All TDRs are initially classified as impaired. Unallocated component—
Deferred loan origination fees/costs	Deferred loan origination fees/costs
Loan servicing	Loan servicing Mortgage servicing rights are amortized in proportion to, and over the period of, estimated net servicing revenues. Refinance activities are considered in estimating the period’s net servicing revenues. Impairment of mortgage servicing rights is assessed based on the fair value of those rights. Fair values are estimated using discounted cash flows based on a current market interest rate. For purposes of measuring impairment, the rights are stratified based on the interest rate risk characteristics of the underlying loans. The amount of impairment recognized is the amount by which the capitalized mortgage servicing rights for a stratum exceed their fair value.

The Company has estimated the remaining useful life of its insurance agency customer list intangible, trust company customer list intangible, and core deposit intangible assets to have a weighted-average of fifteen years, fifteen years, and ten years, respectively. Intangible assets are stated at cost less accumulated amortization.

Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2015, FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis.” The amendments in this ASU affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the amendments: (1) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities; (2) eliminate the presumption that a general partner should consolidate a limited partnership; (3) affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and (4) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. ASU 2015-02 is effective for interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In April 2015, FASB issued ASU 2015-03, “Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The amendments in this ASU require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs is not affected by the amendments in this ASU. The standard is effective for interim and annual reporting periods beginning after December 15, 2015, with early adoption permitted. The guidance should be applied on a retrospective basis. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In April 2015, FASB issued ASU 2015-05, “Intangibles – Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” This ASU provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. ASU 2015-05 is effective for interim and annual reporting periods beginning after December 15, 2015. Early adoption is permitted. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In August 2015, FASB issued ASU 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments.” This ASU requires the acquirer in a business combination to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments in the Update require the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. ASU 2015-16 is effective for interim and annual reporting periods beginning after December 15, 2015. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In January 2016, FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities.” The amendments in this update make targeted improvements to GAAP as follows: 1. Require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. 2. Simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. 3. Eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities. 4. Eliminate the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. 5. Require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 6. Require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. 7. Require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. 8. Clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The standard is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption of item 6 above is permitted for financial statements of fiscal years or interim periods that have not yet been issued. Early adoption of other items above is not permitted. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In February 2016, FASB issued ASU 2016-02, “Leases (Topic 842).” This ASU was issued to increase transparency and comparability among organizations by requiring reporting entities to recognize all leases, including operating, as lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The amendments in this ASU are effective for public entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements.
