Basis of Presentation	Note A – Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and the instructions to Form 10-Q and, accordingly, do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The condensed balance sheet data at December 31, 2014 was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015.
	In preparing consolidated financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet and reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the evaluation of goodwill and other intangible assets for impairment, other-than-temporary impairment of securities and the valuation of deferred tax assets.

	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 FASB Accounting Standards Codification (“ASC”) 810-10, “Consolidation-Overall,” these affiliates have not been included in the condensed consolidated financial statements.

Impact of New Accounting Standards	Note C – Impact of New Accounting Standards
	In May 2014, FASB issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606).” The objective of this ASU is to clarify principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and International Financial Reporting Standards. The guidance in this ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The core principal of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments in this update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The Company is currently reviewing this ASU to determine if it will have an impact on its condensed consolidated financial statements.
	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. The Company anticipates that the adoption of this ASU will not have a material impact on its condensed 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 are 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 condensed 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. The Company anticipates that the adoption of this ASU will not have a material impact on its condensed consolidated financial statements.

Fair_Value_Measurements

Fair Value Measurements	3 Months Ended
	Mar. 31, 2015
Fair Value Measurements	Note D – Fair Value Measurements
	In accordance with ASC 820-10, “Fair Value Measurement – Overall,” 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 NASDAQ Stock Market. 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.
	The Company’s equity securities are generally classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices.
	The Company’s investment in mortgage-backed securities, asset-backed securities, preferred stock with maturities 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.
	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.
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	Securities Available-for-Sale. The fair value of the Company’s available-for-sale securities portfolio is estimated using Level 1 and Level 2 inputs. The Company obtains fair value measurements from an independent pricing service. For Levels 1 and 2, the fair value measurements consider (i) quoted prices in active markets for identical assets and (ii) observable data that may include dealer quotes, market spreads, cash flows, market consensus prepayment speeds, credit information, and a bond’s terms and conditions, among other factors, respectively.
	Interest Rate Lock Commitments. The Company enters into interest rate lock commitments (“IRLCs”) 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.
	Forward Sale Commitments. 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.
	Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
	Impaired Loans. Certain impaired loans are reported at the fair value of the underlying collateral if repayment is expected solely from collateral. Collateral values are estimated using Level 2 inputs based on appraisals of similar properties obtained from a third party valuation service. Fair values are estimated using Level 3 inputs based on appraisals of similar properties obtained from a third party valuation service discounted by management based on historical losses for similar collateral.
	Other Real Estate Owned. Other real estate owned (“OREO”) is reported at fair value less costs to sell. Values are estimated using Level 2 inputs based on appraisals of similar properties obtained from a third party valuation service. For Level 3 inputs, fair values are based on management estimates.
	The following summarizes assets and liabilities measured at fair value at March 31, 2015 and December 31, 2014.

There were no loans measured for impairment using the fair value of the underlying collateral at March 31, 2015. Collateral dependent loans are valued using third party appraisals primarily using the sales comparison approach. The appraisals may be discounted between 25-40% to reflect realizable value based on historical losses which represents an unobservable input. Impaired loans measured for impairment, using the net present value of cash flows, had a recorded investment of $975 thousand with a valuation allowance of $153 thousand at March 31, 2015. Loans valued using the net present value of cash flows are calculated using expected future cash flows with a discount rate equal to the effective yield of the loan. At December 31, 2014, impaired loans had a recorded investment of $1.1 million with a valuation allowance of $67 thousand.
The estimated fair values of the Company’s financial instruments at March 31, 2015 and December 31, 2014, all of which are held or issued for purposes other than trading, were as follows:

The unrealized losses on these debt securities are primarily attributable to changes in market interest rates and current market inefficiencies. The Company has the ability and intent to hold debt securities until maturity, and therefore, no declines are deemed to be other-than-temporary. The unrealized losses on 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.

Credit Quality Information
The Company utilizes a nine grade internal loan rating system for commercial real estate, construction and commercial loans as follows:
	•		Loans rated 10-37: Loans in these categories are considered “pass” rated loans with low to average risk.
	•		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 or a 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 loans over $250 thousand. The assessment of those loans less than $250 thousand is based on the borrower’s ability to pay and not on overall risk. Additionally, the Company monitors the repayment activity for loans less than $250 thousand and if a loan becomes delinquent over 60 days past due, it is reviewed for risk and is subsequently risk rated based on available information such as ability to repay based on current cash flow conditions and workout discussions with the borrower.
Loan Servicing
The Company recognizes as separate assets from their related loans the rights to service mortgage loans for others, either through acquisition of those rights or from the sale or securitization of loans with the servicing rights retained on those loans, based on their relative fair values. To determine the fair value of the servicing rights created, the Company uses the market prices under comparable servicing sale contracts, when available, or alternatively uses a valuation model that calculates the present value of future cash flows to determine the fair value of the servicing rights. In using this valuation method, the Company incorporates assumptions that market participants would use in estimating future net servicing income, which includes estimates of the cost of servicing loans, the discount rate, ancillary income, prepayment speeds and default rates.
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 of 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 balance of capitalized servicing rights, net of valuation allowances, included in other assets at March 31, 2015, was $2.1 million. The fair value of capitalized servicing rights was $3.7 million as of March 31, 2015. Servicing rights of $163 thousand were capitalized during the three months ended March 31, 2015, compared to $49 thousand for the same period in 2014. Amortization of capitalized servicing rights was $357 thousand for the three months ended March 31, 2015, compared to $152 thousand for the same period in 2014.
Following is an analysis of the aggregate changes in the valuation allowance for capitalized servicing rights during the periods indicated:

Impact_of_New_Accounting_Stand1

Impact of New Accounting Standards (Policies)	3 Months Ended
	Mar. 31, 2015
Revenue from Contracts with Customers	In May 2014, FASB issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606).” The objective of this ASU is to clarify principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and International Financial Reporting Standards. The guidance in this ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The core principal of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments in this update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The Company is currently reviewing this ASU to determine if it will have an impact on its condensed consolidated financial statements.
Consolidation	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. The Company anticipates that the adoption of this ASU will not have a material impact on its condensed consolidated financial statements.
Interest	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 are 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 condensed consolidated financial statements.
Intangibles - Goodwill and Other	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. The Company anticipates that the adoption of this ASU will not have a material impact on its condensed consolidated financial statements.
