SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations and Basis of Presentation The Bank’s deposits are insured to the limits specified by the Federal Deposit Insurance Corporation (“FDIC”). The Bank operates 21 banking offices in western Massachusetts and northern Connecticut, and its primary sources of revenue are earnings on loans to small and middle-market businesses and to residential property homeowners and income from securities. Wholly-Owned Subsidiaries and Acquisition On October 21, 2016, we acquired Chicopee Bancorp, Inc. (“Chicopee”), the holding company for Chicopee Savings Bank. The acquisition added eight full-service banking offices located in western Massachusetts. The primary purpose of the acquisition with Chicopee was to expand our presence in western Massachusetts and diversify our market area. The transaction qualified as a tax-free reorganization for federal income tax purposes. Merger consideration paid in the transaction to shareholders of Chicopee totaled $98.8 million, consisting of 11,919,412 shares of Company common stock, net of shares of Chicopee already owned, and shares of Chicopee’s ESOP liquidated to payoff the ESOP loan. We accounted for the transaction using the acquisition method. Accordingly, we recorded acquisition expenses totaling $526,000 and $4.1 million (pre-tax) during 2017 and 2016, respectively. The acquisition method requires an acquirer to recognize the assets acquired and the liabilities assumed at fair value as of the acquisition date. Additionally, our results of operations include Chicopee’s operating results from the date of acquisition. Principles of Consolidation Estimates Reclassifications – Significant Group Concentrations of Credit Risk Cash and Cash Equivalents Securities and Mortgage-Backed Securities Realized gains and losses on sales of securities and mortgage-backed securities are computed using the specific identification method and are included in non-interest income on the trade date. The amortization of premiums and accretion of discounts is determined by using the level yield method to the maturity date. Derivatives - Other-than-Temporary Impairment of Securities Fair Value Hierarchy Level 1 – Valuation is based on quoted prices in active markets for identical assets. Level 1 assets generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets. Level 2 – Valuation is based on observable inputs other than Level 1 prices, such as quoted prices for similar assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets and liabilities. Level 3 – Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. Level 3 assets include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Transfers between levels are recognized at the end of a reporting period, if applicable. Federal Home Loan Bank of Boston Stock Loans Held for Sale Loans Receivable Allowance for Loan Losses The allowance for loan losses is evaluated on a regular basis by management. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of general, allocated and unallocated components, as further described below. General component The general component of the allowance for loan losses is based on historical loss experience adjusted for qualitative factors stratified by the following loan segments: residential real estate, commercial real estate, commercial and industrial, and consumer. Residential real estate loans include classes for residential and home equity. Management uses a rolling average of historical losses based on a time frame appropriate to capture relevant loss data for each loan segment. This historical loss factor is adjusted for the following qualitative factors: trends in delinquencies and nonperforming loans; trends in volume and terms of loans; internal credit ratings; effects of changes in risk selection; underwriting standards and other changes in lending policies, procedures and practices; and national and local economic trends and industry conditions. There were no changes in our policies or methodology pertaining to the general component of the allowance for loan losses during 2017. 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: Commercial real estate – Loans in this segment are primarily income-producing investment properties and owner occupied commercial properties throughout New England. The underlying cash flows generated by the properties or operations can be adversely impacted by a downturn in the economy due to increased vacancy rates or diminished cash flows, which in turn, would have an effect on the credit quality in this segment. Management obtains financial information annually and continually monitors the cash flows of these loans. Residential real estate –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. We require private mortgage insurance for all loans originated with a loan-to-value ratio greater than 80 percent and do not grant subprime loans. Commercial and industrial 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, decreased consumer spending, changes in technology and government spending are examples of what will have an effect on the credit quality in this segment. Consumer loans – Loans in this segment are both secured and unsecured and repayment is dependent on the credit quality of the individual borrower. Allocated component The allocated component relates to loans that are classified as impaired. Impaired loans are identified by analysis of loan performance, internal credit ratings and watch list loans that management believes are subject to a higher risk of loss. Impairment is measured on a loan by loan basis for commercial real estate and commercial and industrial loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. An allowance is established when the discounted cash flows (or collateral value) of the impaired loan is lower than the carrying value of that loan. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, we do not separately identify individual consumer and residential real estate loans for impairment disclosures, unless such loans are nonperforming or subject to a troubled debt restructuring agreement. A loan is considered impaired when, based on current information and events, it is probable that we will be unable to collect all of the 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. We determine 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. We may periodically 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 classified as impaired. While we use our best judgment and information available, the ultimate appropriateness of the allowance is dependent upon a variety of factors beyond our control, including the performance of our loan portfolio, the economy, changes in interest rates and the view of the regulatory authorities toward loan classifications. Unallocated component An unallocated component may be maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating allocated and general reserves in the portfolio. Loans Acquired with Deteriorated Credit Quality – Bank-owned Life Insurance – Transfers and Servicing of Financial Assets Premises and Equipment Years Buildings 39 Leasehold Improvements 5-20 Furniture and Equipment 3-7 The cost of maintenance and repairs is charged to expense when incurred. Major expenditures for betterments are capitalized and depreciated. Other Real Estate Owned Servicing Servicing fee income is recorded for fees earned for servicing loans, which is included in service charges and fee income. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Impairment of Long-lived Assets Goodwill is measured as the excess of the cost of a business combination over the sum of the amounts assigned to identifiable intangible assets acquired less liabilities assumed. Goodwill is not amortized but rather assessed for impairment annually or more frequently if circumstances warrant. Management has the option of first assessing qualitative factors, such as events and circumstances, to determine whether it is more likely than not, meaning a likelihood of more than 50%, the value of a reporting unit is less than its carrying amount. If, after considering all relevant events and circumstances, management determines it is not more likely than not the fair value of a reporting unit is less than its carrying amount, then performing an impairment test is unnecessary. For the year ended December 31, 2017, management determined that it was not more likely than not the fair value of the reporting unit (the consolidated Company, in our case) was less than its carrying amount. If management had determined otherwise, a fair value analysis would have been completed to determine the impairment and necessary write-down of goodwill.

The amortized cost and fair value of available-for-sale debt securities at December 31, 2017, by final maturity, are shown below. Actual maturities may differ from contractual maturities because certain issuers have the right to call or prepay obligations. Also, because mortgage-backed securities require periodic principal paydowns, they are not included in the maturity categories in the following maturity summary.

During the three months ended March 31, 2016, the Company transferred its held-to-maturity portfolio of $232.8 million to available-for-sale. As a result of this transfer, the Company has tainted their held-to-maturity portfolio and is prohibited from classifying future purchases as held-to-maturity for a period of at least two years.

Receivables [Abstract]
LOANS	3. LOANS December 31, 2017 2016 (In thousands) Loans consisted of the following amounts: Commercial real estate $ 732,616 $ 720,741 Residential real estate: Residential 557,752 522,083 Home equity 92,599 92,083 Commercial and industrial 238,502 222,286 Consumer 4,478 4,424 Unamortized total loans 1,625,947 1,561,617 Premiums and deferred loan fees and costs, net 4,734 4,867 Allowance for loan losses (10,831 ) (10,068 ) $ 1,619,850 $ 1,556,416 During 2017 and 2016, we purchased residential real estate loans aggregating $48.2 million and $108.4 million, respectively. These purchased loans are subject to underwriting standards that are consistent with our originated loans and we consider the risk attributes to be similar to originated loans. We have transferred a portion of our originated commercial loans to participating lenders. The amounts transferred have been accounted for as sales and are therefore not included in our accompanying consolidated balance sheets. We share ratably with our participating lenders in any gains or losses that may result from a borrower’s lack of compliance with contractual terms of the loan. We continue to service the loans on behalf of the participating lenders and, as such, collect cash payments from the borrowers, remit payments (net of servicing fees) to participating lenders and disburse required escrow funds to relevant parties. At December 31, 2017 and 2016, we serviced commercial loans for participants aggregating $32.6 million and $42.6 million, respectively. Mortgage loans serviced for others are not included in the accompanying consolidated balance sheets. The unpaid balances of these loans totaled $65.8 million and $75.2 million at December 31, 2017 and 2016, respectively. Net service fee income of $63,000, $12,500 and $4,000 was recorded for the years ended December 31, 2017, 2016 and 2015, respectively, and is included in service charges and fees on the consolidated statements of net income. Residential real estate mortgages are originated by the Bank both for its portfolio and for sale into the secondary market. The Bank may sell its loans to institutional investors such as the Federal Home Loan Mortgage Corporation. Under loan sale and servicing agreements with the investor, the Bank generally continues to service the residential real estate mortgages. The Bank pays the investor an agreed upon rate on the loan, which is less than the interest rate received from the borrower. The Bank retains the difference as a fee for servicing the residential real estate mortgages. The Bank capitalizes mortgage servicing rights at their fair value upon sale of the related loans, amortizes the asset over the estimated life of the serviced loan, and periodically assesses the asset for impairment. The significant assumptions used by a third party to estimate the fair value of capitalized servicing rights at December 31, 2017, include weighted average prepayment speed for the portfolio using the Public Securities Association Standard Prepayment Model (203 PSA), weighted average internal rate of return (10.05%), weighted average servicing fee (0.25%), and net cost to service loans ($59.39 per loan). The estimated fair value of capitalized servicing rights may vary significantly in subsequent periods primarily due to changing market interest rates, and their effect on prepayment speeds and discount rates. A summary of the activity in the balances of mortgage servicing rights follows: Years Ended December 31, 2017 2016 (In thousands) Balance at the beginning of year: $ 465 $ — Capitalized mortgage servicing rights — 502 Amortization (113 ) (37 ) Balance at the end of year $ 352 $ 465 Fair value at the end of year $ 528 $ 628 An analysis of changes in the allowance for loan losses by segment for the years ended December 31, 2017, 2016 and 2015 is as follows: Commercial Real Estate Residential Real Estate Commercial and Industrial Consumer Unallocated Total (In thousands) Balance at December 31, 2014 $ 3,705 $ 2,053 $ 2,174 $ 15 $ 1 $ 7,948 Provision 151 428 605 46 45 1,275 Charge-offs — (58 ) (345 ) (73 ) — (476 ) Recoveries — 8 51 34 — 93 Balance at December 31, 2015 $ 3,856 $ 2,431 $ 2,485 $ 22 $ 46 $ 8,840 Provision (credit) (668 ) 579 575 135 (46 ) 575 Charge-offs (170 ) (157 ) — (159 ) — (486 ) Recoveries 1,065 9 25 40 — 1,139 Balance at December 31, 2016 $ 4,083 $ 2,862 $ 3,085 $ 38 $ — $ 10,068 Provision (credit) 779 433 (144 ) 288 4 1,360 Charge-offs (292 ) (148 ) (289 ) (319 ) — (1,048 ) Recoveries 142 164 81 64 — 451 Balance at December 31, 2017 $ 4,712 $ 3,311 $ 2,733 $ 71 $ 4 $ 10,831 Further information pertaining to the allowance for loan losses by segment at December 31, 2017 and 2016 follows: Commercial Real Estate Residential Real Estate Commercial and Industrial Consumer Unallocated Total (In thousands) December 31, 2017 Amount of allowance for impaired loans $ — $ — $ — $ — $ — $ — Amount of allowance for non-impaired loans 4,712 3,311 2,733 71 4 10,831 Total allowance for loan losses $ 4,712 $ 3,311 $ 2,733 $ 71 $ 4 $ 10,831 Impaired loans $ 3,674 $ 3,964 $ 2,766 $ 120 $ — $ 10,524 Non-impaired loans 716,571 642,787 234,582 4,358 — 1,598,298 Impaired loans acquired with deteriorated credit quality 12,371 3,600 1,154 — — 17,125 Total loans $ 732,616 $ 650,351 $ 238,502 $ 4,478 $ — $ 1,625,947 December 31, 2016 Amount of allowance for impaired loans $ — $ — $ — $ — $ — $ — Amount of allowance for non-impaired loans 4,083 2,862 3,085 38 — 10,068 Total allowance for loan losses $ 4,083 $ 2,862 $ 3,085 $ 38 $ — $ 10,068 Impaired loans $ 3,335 $ 452 $ 3,042 $ — $ — $ 6,829 Non-impaired loans 701,766 609,107 217,972 4,424 — 1,533,269 Impaired loans acquired with deteriorated credit quality 15,640 4,607 1,272 — — 21,519 Total loans $ 720,741 $ 614,166 $ 222,286 $ 4,424 $ — $ 1,561,617 The following is a summary of past due and nonaccrual loans by class at December 31, 2017 and 2016: 30 – 59 Days Past Due 60 – 89 Days Past Due Greater than 90 Days Past Due Total Past Due Past Due 90 Days or More and Still Accruing Non-Accrual Loans (In thousands) December 31, 2017 Commercial real estate $ 1,951 $ 144 $ 290 $ 2,385 $ — $ 2,959 Residential real estate: Residential 2,992 1,480 1,911 6,383 — 5,961 Home equity 635 — 48 683 — 696 Commercial and industrial 1,731 797 162 2,690 — 3,019 Consumer 65 — 41 106 — 120 Total $ 7,374 $ 2,421 $ 2,452 $ 12,247 $ — $ 12,755 December 31, 2016 Commercial real estate $ 1,400 $ 1,338 $ 361 $ 3,099 $ — $ 4,452 Residential real estate: Residential 3,160 1,006 974 5,140 — 5,744 Home equity 347 46 — 393 — 120 Commercial and industrial 509 368 41 918 — 3,714 Consumer 92 43 8 143 — 27 Total $ 5,508 $ 2,801 $ 1,384 $ 9,693 $ — $ 14,057 The following is a summary of impaired loans by class: Year Ended At December 31, 2017 December 31, 2017 Recorded Investment Unpaid Principal Balance Related Allowance Average Recorded Investment Interest Income Recognized (In thousands) Impaired Loans: (1) Commercial real estate $ 16,045 $ 18,773 $ — $ 18,215 $ 842 Residential real estate 6,816 7,298 — 6,630 45 Home equity 748 783 359 4 Commercial and industrial 3,920 9,215 — 4,388 237 Consumer 120 129 93 — Total impaired loans $ 27,649 $ 36,198 $ — $ 29,685 $ 1,128 (1) Includes loans acquired with deteriorated credit quality and performing troubled debt restructurings.

No interest income was recognized for impaired loans on a cash-basis method during the years ended December 31, 2017 or 2016. Interest income recognized during the year ended December 31, 2017 related to performing purchased impaired loans and TDRs while activity during the year ended December 31, 2016 related to TDRs. We may periodically 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”). These concessions could include a reduction in the interest rate on the loan, payment extensions, postponement or forgiveness of principal, forbearance or other actions intended to maximize collection. All TDRs are classified as impaired. When we modify loans in a TDR, we measure impairment similar to other impaired loans based on the present value of expected future cash flows, discounted at the contractual interest rate of the original loan agreement, or use the current fair value of the collateral, less selling costs for collateral dependent loans. If we determine that the value of the modified loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized through a specific allowance or a charge-off to the allowance. Nonperforming TDRs are shown as nonperforming loans. The following table summarizes TDRs at the dates indicated: Year Ended Year Ended December 31, 2017 December 31, 2016 Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment (Dollars in thousands) (Dollars in thousands) Troubled Debt Restructurings: Commercial Real Estate — $ — $ — 2 $ 1,946 $ 1,946 Commercial and Industrial 1 112 112 3 2,899 2,899 Residential — — — 4 555 555 Total 1 $ 112 $ 112 9 $ 5,400 $ 5,400 During the year ended December 31, 2016, a substandard impaired loan relationship in the amount of $4.6 million was designated a TDR. The Bank entered into a forbearance agreement which offered an interest only period. Due to the borrower continuing to experience declining sales, the interest only period was extended during the second quarter of 2016, resulting in the TDR classification. The loans are on non-accrual and are current. The loans are measured for impairment quarterly and appropriate reserves/charge offs have been taken. There were no significant loans modified during the year ended December 31, 2017. During the years ended December 31, 2017 and 2016, no TDRs defaulted (defined as 30 days or more past due) within 12 months of restructuring. Upon our merger with Chicopee, we acquired 3 TDR loans totaling $440,000 that subsequently defaulted within the year of restructuring. As of December 31, 2017, we have not committed to lend any additional funds for loans that are classified as impaired. There were $256,000 in charge-offs on TDRs during the year ended December 31, 2017. There were no charge-offs on TDRs during the year ended December 31, 2016. Loans Acquired with Deteriorated Credit Quality The following is a summary of loans acquired with evidence of credit deterioration from Chicopee as of December 31, 2017. Contractual Required Payments Receivable Cash Expected To Be Collected Non- Accretable Discount Accretable Yield Loans Receivable (In thousands) Balance at December 31, 2016 $ 37,437 $ 29,040 $ 8,397 $ 7,521 $ 21,519 Collections (4,289 ) (3,504 ) (785 ) (750 ) (2,754 ) Dispositions (3,786 ) (2,378 ) (1,408 ) (738 ) (1,640 ) Balance at December 31, 2017 $ 29,362 $ 23,158 $ 6,204 $ 6,033 $ 17,125 Credit Quality Information We use an eight-grade internal loan rating system for commercial real estate and commercial and industrial loans. Performing residential real estate, home equity and consumer loans are grouped with “Pass” rated loans. Nonperforming residential real estate, home equity and consumer loans are monitored individually for impairment and risk rated as “substandard.” Loans rated 1 – 4 are considered “Pass” or “Pass Watch” rated loans with acceptable risk. Loans rated 5 are considered “Special Mention.” These loans exhibit potential credit weaknesses or downward trends and are being closely monitored by us. Loans rated 6 are considered “Substandard.” Generally, a loan is considered substandard if the borrower exhibits a well-defined weakness that may be inadequately protected by the current net worth and cash flow capacity to pay the current debt. Loans rated 7 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 and that a partial loss of principal is likely. Loans rated 8 are considered uncollectible and of such little value that their continuance as loans is not warranted. On an annual basis, or more often if needed, we formally review the ratings on all commercial real estate and commercial and industrial loans. We engage an independent third party to review a significant portion of loans within these segments on at least an annual basis. We use the results of these reviews as part of our annual review process. In addition, management utilizes delinquency reports, the watch list and other loan reports to monitor credit quality in other segments. Construction loans are reported within commercial real estate loans and total $84.4 million and $88.9 million at December 31, 2017 and 2016, respectively.

Annually, or more frequently if events or changes in circumstances warrant such evaluation, the Company evaluates its goodwill for impairment. No goodwill impairment was recorded during the year ended December 31, 2017. During the three months ended March 31, 2017, management completed their evaluation of premises and equipment acquired from Chicopee, which resulted in a $2.4 million adjustment to the provisional fair values of bank premises acquired and a $1.4 million reduction in goodwill. The remaining adjustments to goodwill of $140,000 during the three months ended March 31, 2017 resulted from information obtain during the quarter about events and circumstances that existed as of the acquisition date. Core Deposit Intangibles In connection with the assumption of $545.7 million of deposit liabilities from the Chicopee acquisition in October 2016, of which $345.2 million were core deposits, the Bank recorded a core deposit intangible of $4.5 million. The resulting core deposit intangible is amortized over twelve years using the straight-line method. Core deposit intangibles are summarized as follows: Year Ended December 31, 2017 (In thousands) Core deposit intangible, net at December 31, 2016 $ 4,438 Accumulated amortization (375 ) Core deposit intangible, net at December 31, 2017 $ 4,063 Amortization expense was $375,000 and $73,000 for the years ended December 31, 2017 and 2016, respectively.

Restricted Stock Awards – In January 2015, 48,560 shares were granted under this plan and vest ratably over five years. The fair market value of shares awarded, based on the market price at the date of grant, was recorded as unearned compensation and is being amortized over the applicable vesting period. In 2016, the Compensation Committee (the “Committee”) approved the long-term incentive program (the “LTI Plan”). The LTI Plan provides a periodic award that is both performance and retention based in that it is designed to recognize the executive’s responsibilities, reward demonstrated performance and leadership and to retain such executives. The objective of the LTI Plan is to align compensation for the named executive officers and directors over a multi-year period directly with the interests of our shareholders by motivating and rewarding creation and preservation of long-term financial strength, shareholder value and relative shareholder return. The LTI Plan includes eligible officers of the Company who are nominated by the Company’s Chief Executive Officer and approved by the Committee. The LTI Plan is triggered by the Company’s achievement of satisfactory safety and soundness results from its most recent regulatory examination and additional performance metric as determined upon issuance. Stock grants made through the 2016 LTI Plan will be a combination of 50% time-vested restricted stock and 50% performance-based restricted stock. In May 2016, 62,740 shares were granted under the LTI Plan. Of this total, 36,543 shares are retention-based, with 10,352 vesting in one year and 26,191 vesting ratably over a three year period. The remaining 26,197 shares granted are performance based and are subject to the achievement of the 2016 LTI performance metric before vesting is realized after a three year period. Performance shares will be earned based upon how the Company performs relative to threshold and target absolute goals (i.e. Company-specific, not relative to a peer index) over the three-year performance period. As a result of the Tax Cuts and Jobs Act of 2017, the return on equity performance metrics were adjusted to incorporate the impact and benefits of the corporate tax rate reductions thereunder. The original and adjusted threshold and target metrics under the 2016 Plan are as follows: Return on Equity Metrics Threshold Target Original metrics 5.85 % 6.32 % Adjusted metrics 6.38 % 6.79 % Participants will be able to earn between 50% (for threshold performance) and 100% (for target performance) for the performance shares but will not earn additional shares if performance exceeds target performance. In May 2017, 89,042 shares were granted under the LTI Plan. Of this total, 55,159 shares are retention-based, with 21,276 vesting in one year and 33,883 vesting ratably over a three year period. The remaining 33,883 shares granted are performance based and are subject to the achievement of the 2017 LTI performance metric before vesting is realized after a three year period. For the performance shares, the primary performance metric for 2017 awards is return on equity. Performance shares will be earned based upon how the Company performs relative to threshold, target and maximum absolute goals (i.e. Company-specific, not relative to a peer index) on an annual performance period, but will be distributed at the end of the three year period. As a result of the Tax Cuts and Jobs Act of 2017, the return on equity performance metrics were adjusted to incorporate the impact and benefits of the corporate tax rate reductions thereunder. The original and adjusted threshold, target and maximum metrics under the 2017 Plan are as follows: Return on Equity Metrics Performance Period Ending Original Threshold Adjusted Threshold Original Target Adjusted Target Original Maximum Adjusted Maximum December 31, 2017 6.00 % 6.00 % 6.60 % 6.60 % 7.30 % 7.30 % December 31, 2018 6.30 % 6.87 % 7.00 % 7.63 % 7.60 % 8.28 % December 31, 2019 6.50 % 7.09 % 7.20 % 7.85 % 7.90 % 8.61 % Participants will be able to earn between 50% (for threshold performance), 100% (for target performance) and 150% (for maximum performance). The fair market value of shares awarded, based on the market price at the date of grant, is recorded as unearned compensation and amortized over the applicable vesting period. Shares granted under performance-based conditions are monitored on a quarterly basis in order to compare actual results to the performance metric established, with any necessary adjustments being recognized through share-based compensation expense and unearned compensation. At December 31, 2017, an additional 315,658 shares were available for future grants under this plan. A summary of the status of unvested restricted stock awards at December 31, 2017 is presented below: Shares Weighted Balance at December 31, 2016 91,371 $ 7.51 Shares granted 89,042 10.15 Shares vested (41,580 ) 8.24 Balance at December 31, 2017 138,833 $ 8.98 The aggregate fair value of restricted stock vested during 2017 was $432,000. We recorded total expense for restricted stock awards of $649,000, $262,000 and $131,000 for the years ended December 31, 2017, 2016, and 2015, respectively. Tax benefits related to equity incentive plan expense were $42,000, $89,000 and $44,000 for the years ended December 31, 2017, 2016 and 2015, respectively. Unrecognized compensation cost for stock awards was $798,000 at December 31, 2017 with a remaining term of 1.7 years. Employee Stock Ownership Plan - In January 2007, as part of the second-step stock conversion, we provided an additional loan to the ESOP Trust which was used to purchase 4.0%, or 736,000 shares, of the 18,400,000 shares of common stock sold in the offering. The 2002 and 2007 loans bear interest equal to 8.0% and provide for annual payments of interest and principal. At December 31, 2017, the remaining principal balances are payable as follows: Years Ending December 31, Amount (In thousands) 2018 $ 447 2019 447 2020 447 2021 447 2022 447 Thereafter 4,900 $ 7,135 We have committed to make contributions to the ESOP sufficient to support the debt service of the loans. The loans are secured by the shares purchased, which are held in a suspense account for allocation among the participants as the loans are paid. Total compensation expense applicable to the ESOP amounted to $958,000, $630,000 and $582,000 for the years ended December 31, 2017, 2016 and 2015, respectively. Shares held by the ESOP include the following at December 31, 2017 and 2016: 2017 2016 Allocated 899,969 832,308 Committed to be allocated 93,679 79,082 Unallocated 791,102 884,781 Total 1,784,750 1,796,171 Cash dividends declared and received on allocated shares are allocated to participants and charged to retained earnings. Cash dividends declared and received on unallocated shares are held in suspense and are applied to repay the outstanding debt of the ESOP. The fair value of unallocated shares was $8.6 million and $8.5 million at December 31, 2017 and 2016, respectively. ESOP shares are considered outstanding for earnings per share calculations when they are committed to be allocated. Unallocated ESOP shares are excluded from earnings per share calculations. The cost of unearned shares to be allocated to ESOP participants for future services not yet performed is reflected as a reduction of shareholders’ equity.

The NAV is used as a practical expedient to estimate fair value. This practical expedient would not be used if it was determined to be probable that the funds will sell the underlying investments for an amount different from the reported NAV. Participant transactions (purchases and sales) may occur daily. The preceding method described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The following table summarizes the investments for which fair value is measured using NAV per share as a practical expedient for the years ended December 31, 2017 and 2016. There are no pertinent redemption restrictions for these investments; the redemption notice period is applicable only to the Plan.

The target allocation mix for the pension plan for 2017 was an equity-based investment deployment of 50% of total portfolio assets based on advice received from an external advisory firm with confirmation by the Bank’s Investment Committee. The remainder of the portfolio is allocated to fixed income at 50% of total assets. The investment objective is to diversify investments across a spectrum of investment types to limit risks from large market swings and to provide anticipated stabilized investment returns. Trustees of the Plan select investment managers for the portfolio and a second investment advisory firm is retained to provide allocation analysis. The overall investment objective is to diversify equity investments across a spectrum of types, small cap, large cap and international, along with investment styles such as growth and value. We estimate that the benefits to be paid from the pension plan for years ended December 31 are as follows: Year Benefit Payments to Participants (In thousands) 2018 $ 1,189 2019 883 2020 1,131 2021 1,268 2022 1,667 In aggregate for 2023 – 2027 14,592 We have not yet determined the amount of the contribution we expect to make to the plan during the fiscal year ending December 31, 2018. 401(k)

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES AND HEDGING ACTIVITIES	11. DERIVATIVES AND HEDGING ACTIVITIES Risk Management Objective of Using Derivatives We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of our assets and liabilities and the use of derivative financial instruments. Specifically, we entered into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are used to manage differences in the amount, timing, and duration of our known or expected cash receipts and our known or expected cash payments principally related to certain variable rate borrowings. Fair Values of Derivative Instruments on the Balance Sheet The table below presents the fair value of our derivative financial instruments designated as hedging instruments as well as our classification on the balance sheet as of December 31, 2017.

Cash Flow Hedges of Interest Rate Risk Our objectives in using interest rate derivatives are to add stability to interest income and expense and to manage our exposure to interest rate movements. To accomplish this objective, we enter into interest rate swaps as part of our interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for our making fixed payments. The following table presents information about our cash flow hedges at December 31, 2017 and 2016: December 31, 2017 Notional Weighted Weighted Average Rate Estimated Fair Amount Maturity Receive Pay Value (In thousands) (In years) (In thousands) Interest rate swaps on FHLBB borrowings $ 55,000 3.3 1.64 % 2.93 % $ (2,152 ) Total cash flow hedges $ 55,000 3.3 $ (2,152 ) December 31, 2016 Notional Weighted Weighted Average Rate Estimated Fair Amount Maturity Received Paid Value (In thousands) (In years) (In thousands) Interest rate swaps on FHLBB borrowings $ 75,000 3.4 0.92 % 2.46 % $ (3,152 ) Total cash flow hedges $ 75,000 3.4 $ (3,152 ) During 2016, we terminated a forward-starting interest rate swap with a notional amount of $32.5 million and incurred a termination fee of $3.4 million. During 2015, we terminated forward-starting interest rate swaps with a notional amount of $47.5 million and incurred a termination fee of $2.4 million. The termination fees are being amortized as a reclassification of other comprehensive income into interest expense over the terms of the previously hedged borrowings, which were six and five years for the swaps terminated in 2016 and 2015, respectively. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (outside of earnings), net of tax, and subsequently reclassified to earnings when the hedged transaction affects earnings. The ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. We assess the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged transactions. We did not recognize any hedge ineffectiveness in earnings in 2017 or 2016. We are hedging our exposure to the variability in future cash flows for forecasted borrowings over a maximum period of six years (excluding forecasted payment of variable interest on existing financial instruments). The table below presents the pre-tax net loss of our cash flow hedges for the periods indicated. Amount of Gain (Loss) Recognized in OCI on Derivative (Effective Portion) Years Ended December 31, 2017 2016 2015 (In thousands) Interest rate swaps $ 31 $ (1,126 ) $ (3,337 ) Amounts reported in accumulated other comprehensive loss related to these derivatives are reclassified to interest expense as interest payments are made on our designated rate sensitive liabilities. During the years ended December 31, 2017, 2016 and 2015, we reclassified $2.0 million, $1.6 million and $742,000 into interest expense, respectively. During the next 12 months, we estimate that $1.7 million will be reclassified as an increase in interest expense. During the years ended December 31, 2017, 2016 and 2015, no gains or losses were reclassified from accumulated other comprehensive loss into income for ineffectiveness on cash flow hedges. Credit-risk-related Contingent Features By using derivative financial instruments, we expose the Company to credit risk. Credit risk is the risk of failure by the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes us, which creates credit risk for us. When the fair value of a derivative is negative, we owe the counterparty and, therefore, it does not possess credit risk. The credit risk in derivative instruments is mitigated by entering into transactions with highly-rated counterparties that we believe to be creditworthy and by limiting the amount of exposure to each counterparty. We have agreements with our derivative counterparties that contain a provision where if we default on any of our indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then we could also be declared in default on our derivative obligations. We also have agreements with certain of our derivative counterparties that contain a provision where if we fail to maintain our status as well capitalized, then the counterparty could terminate the derivative positions and we would be required to settle our obligations under the agreements. Certain of our agreements with our derivative counterparties contain provisions where if a formal administrative action by a federal or state regulatory agency occurs that materially changes our creditworthiness in an adverse manner, we may be required to fully collateralize our obligations under the derivative instrument. At December 31, 2017 and 2016, we had a net liability position of $2.2 million and $3.2 million with our counterparties, respectively. As of December 31, 2017, we had minimum collateral posting thresholds with certain of our derivative counterparties and had mortgage-backed securities with a fair value of $3.1 million posted as collateral against our obligations under these agreements. If we had breached any of these provisions at December 31, 2017, we could have been required to settle our obligations under the agreements at the termination value.

REGULATORY CAPITAL

Banking and Thrift [Abstract]
REGULATORY CAPITAL	12. REGULATORY CAPITAL 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 regulators that, if undertaken, could have a direct material effect on our consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, 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 capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to savings and loan holding companies. Effective January 1, 2015, federal banking regulations changed with regard to minimum capital requirements for community banking institutions. The regulations require a minimum ratio of common equity Tier 1 capital to risk-weighted assets of 4.5%, a minimum ratio of Tier 1 capital to risk-weighted assets of 6% and a minimum leverage ratio of 4% for all banking organizations. Additionally, community banking institutions must maintain a capital conservation buffer of common equity Tier 1 capital, Tier 1 capital or Total capital in an amount greater than 2.5% of total risk-weighted assets to avoid being subject to limitations on capital distributions and discretionary bonuses. The capital conservation buffer and certain new deductions from and adjustments to regulatory capital are being phased in over several years. The required minimum conservation buffer is 1.25% as of December 31, 2017 and will increase to 1.875% on January 1, 2018 and 2.50% on January 1, 2019. Management believes that the Company’s capital levels will remain characterized as “well-capitalized” throughout the phase in periods. Western New England Bancorp’s and the Bank’s capital ratios as of December 31, 2017 and 2016 are set forth in the following table. As of December 31, 2017, the most recent notification from the Office of the Comptroller of the Currency categorized the Bank as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized,” the Bank must maintain minimum total risk-based, Tier 1 risk based and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since that notification that management believes have changed the Bank’s category.

On June 24, 2015, the Board of Directors announced a renewal of the repurchase program under which the Company may purchase up to 711,733 shares of its outstanding common stock, to be affected via a combination of Rule 10b5-1 plans and discretionary share repurchases. This plan began July 24, 2015 and as of January 31, 2017 the repurchase program was completed. On January 31, 2017, the Board of Directors authorized an additional stock repurchase program under which the Company may purchase up to 3,047,000 shares, or 10%, of its outstanding common stock, to be affected via a combination of Rule 10b5-1 plans and discretionary share repurchases. As of December 31, 2017, there were 2,440,609 shares remaining to be purchased. We are subject to dividend restrictions imposed by various regulators, including a limitation on the total of all dividends that the Bank may pay to the Company in any calendar year, to an amount that shall not exceed the Bank’s net income for the current year, plus its net income retained for the two previous years, without regulatory approval. At December 31, 2017 and 2016, the Bank had no retained earnings available for payment of dividends without prior regulatory approval. In addition, the Bank may not declare or pay dividends on, and we may not repurchase, any of our shares of common stock if the effect thereof would cause shareholders’ equity to be reduced below applicable regulatory capital maintenance requirements or if such declaration, payment or repurchase would otherwise violate regulatory requirements. The Bank will be prohibited from paying cash dividends to the Company to the extent that any such payment would reduce the Bank’s capital below required capital levels. Accordingly, $131.4 million and $129.9 million of our equity in the net assets of the Bank was restricted at December 31, 2017 and 2016, respectively. The only funds available for the payment of dividends on our capital stock will be cash and cash equivalents held by us, dividends paid from the Bank to us, and borrowings.

If any portion of the reserve is used for purposes other than to absorb loan losses, approximately 150% of the amount actually used, limited to the amount of the reserve, would be subject to taxation in the fiscal year in which used. As the Bank intends to use the reserve solely to absorb loan losses, a deferred tax liability of $2.6 million has not been provided. We do not have any uncertain tax positions at December 31, 2017 or 2016 which require accrual or disclosure. We record interest and penalties as part of income tax expense. No interest was recorded for the years ended December 31, 2017 and 2016, and no penalties were recorded for the years ended December 31, 2017, 2016 and 2015. Our income tax returns are subject to review and examination by federal and state tax authorities. We are currently open to audit under the applicable statutes of limitations by the Internal Revenue Service for the years ended December 31, 2014 through 2017. The years open to examination by state taxing authorities vary by jurisdiction; however, no years prior to 2014 are open. The Company had net operating loss carryforwards brought over in the Chicopee merger of $3.5 million, which was used during the year ended December 31, 2017. As a result of the Tax Act, the Company recorded $4.0 million in additional income tax expense which includes a tax benefit of $2.1 million relating to the impact of the rate change on deferred tax items originally recorded through other comprehensive income (net unrealized losses on securities available for sale, change in fair value of derivatives used for cash flow hedges and actuarial losses on the defined benefit pension plan). This accounting treatment effectively stranded $2.1 million of deferred tax items in accumulated other comprehensive income (“AOCI”). In February 2018, the FASB issued ASU 2018-02, Income Statement—Reporting Comprehensive Income

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	15. COMMITMENTS AND CONTINGENCIES In the normal course of business, various commitments and contingent liabilities are outstanding, such as standby letters of credit and commitments to extend credit with off-balance-sheet risk that are not reflected in the consolidated financial statements. Financial instruments with off-balance-sheet risk involve elements of credit, interest rate, liquidity and market risk. We do not anticipate any significant losses as a result of these transactions. The following summarizes these financial instruments and other commitments and contingent liabilities at their contract amounts: December 31, 2017 2016 (In thousands) Commitments to extend credit: Unused lines of credit $ 229,436 $ 217,193 Loan commitments 40,878 41,285 Existing construction loan agreements 42,555 35,702 Standby letters of credit 9,138 7,090 We use the same credit policies in making commitments and conditional obligations as for on balance sheet instruments. Commitments to extend credit are agreements to lend to a customer as long as 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 some commitments expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. We evaluate each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by us upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, and income-producing commercial properties. Standby letters of credit are written conditional commitments issued by us that guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. At December 31, 2017, outstanding commitments to extend credit totaled $322.0 million, with $47.4 million in fixed rate commitments with interest rates ranging from 1.49% to 18.00% and $274.6 million in variable rate commitments. At December 31, 2016, outstanding commitments to extend credit totaled $301.3 million, with $40.0 million in fixed rate commitments with interest rates ranging from 1.99% to 18.00% and $261.3 million in variable rate commitments. We also have risk participation agreements (“RPAs”) with another financial institution. The RPAs are a guarantee to share credit risk associated with an interest rate swap on participation loans in the event of counterparty default. As such, we accept a portion of the credit risk in order to participate in the loans and we receive a one-time fee. The interest rate swap is collateralized (generally by real estate or business assets) by us and the third party, which limits the credit risk associated with the RPAs. Per the terms of the RPAs, we must pledge collateral equal to our exposure for the interest rate swap. We monitor overall collateral as part of our off-balance sheet liability analysis, and at December 31, 2017, believe sufficient collateral is available to cover potential swap losses. At December 31, 2017, we had one RPA with a fair value of $529,000. The remaining term of this RPA at December 31, 2017, which corresponds to the term of the underlying swaps, was 10 years. In addition, we had an RPA with a net fair value of $144,000 and a remaining term of 20 years at December 31, 2017. Also at December 31, 2017 we had one RPA with a negative fair value of ($292,000) which had a 20 year term remaining. Under these agreements we guarantee a percentage of the amount in the event of a default. The maximum potential future payment guaranteed by us cannot be readily estimated, but is dependent upon the fair value of the interest rate swaps and the probability of a default event. If an event of default on all contracts had occurred at December 31, 2017, we would have been required to make payments of approximately $366,000. In the ordinary course of business, we are party to various legal proceedings, none of which, in our opinion, will have a material effect on our consolidated financial position or results of operations. We lease facilities and certain equipment under cancelable and non-cancelable leases expiring in various years through the year 2047. Certain of the leases provide for renewal periods for up to forty years at our discretion. Rent expense under operating leases was $1,106,000, $798,000, and $677,000 for the years ended December 31, 2017, 2016, and 2015, respectively. Aggregate future minimum rental payments under the terms of non-cancelable operating leases at December 31, 2017, are as follows: Years Ending Amount (In thousands) 2018 $ 1,100 2019 1,038 2020 946 2021 880 2022 763 Thereafter 4,651 $ 9,378 Investment Commitments The Bank is a limited partner in a Small Business Investment Company (“SBIC”) and committed to contribute capital of $3.0 million to the limited partnerships. The SBIC currently has a book value of $947,000 at December 31, 2017 and is included in other assets. Employment and change of control agreements We have entered into employment and change of control agreements with certain senior officers. The initial term of the employment agreements is for three years subject to separate one-year extensions as approved by the Board of Directors at the end of each applicable fiscal year. Each employment agreement provides for minimum annual salaries, discretionary cash bonuses and other fringe benefits as well as severance benefits upon certain terminations of employment that are not for cause. The change of control agreements expire one year following a notice of non-extension and only provide for severance benefits upon certain terminations of employment that are not for cause and that are related to a change of control of the Company or the Bank.

Risks and Uncertainties [Abstract]
CONCENTRATIONS OF CREDIT RISK	16. CONCENTRATIONS OF CREDIT RISK Most of our loans consist of residential and commercial real estate loans located in western Massachusetts. As of December 31, 2017 and 2016, our residential and commercial related real estate loans represented 85.1% and 85.5% of total loans, respectively. Our policy for collateral requires that the amount of the loan may not exceed 100% and 85% of the appraised value of the property for residential and commercial real estate, respectively, at the date the loan is granted. For residential loans, in cases where the loan exceeds 80%, private mortgage insurance is typically obtained for that portion of the loan in excess of 80% of the appraised value of the property.

Fair Value Disclosures [Abstract]
FAIR VALUE OF ASSETS AND LIABILITIES	17. FAIR VALUE OF ASSETS AND LIABLITIES Determination of Fair Value We use fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for our various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Methods and assumptions for valuing our financial instruments are set forth below. Estimated fair values are calculated based on the value without regard to any premium or discount that may result from concentrations of ownership of a financial instrument, possible tax ramifications or estimated transaction cost. Cash and cash equivalents - Securities and mortgage-backed securities Federal Home Loan Bank and other restricted stock Loans receivable - Accrued interest - Deposit liabilities - Short-term borrowings and long-term debt - Interest rate swaps Commitments to extend credit Assets and Liabilities Measured at Fair Value on a Recurring Basis Assets and liabilities measured at fair value on a recurring basis are summarized below: December 31, 2017 Level 1 Level 2 Level 3 Total Assets: (In thousands) Government-sponsored mortgage-backed securities $ — $ 182,001 $ — $ 182,001 U.S. government guaranteed mortgage-backed securities — 16,254 — 16,254 Corporate bonds — 56,144 — 56,144 State and municipal bonds — 3,239 — 3,239 Government-sponsored enterprise obligations — 24,381 — 24,381 Mutual funds 6,397 — — 6,397 Total assets $ 6,397 $ 282,019 $ — $ 288,416 Liabilities: Interest rate swaps $ — $ 2,152 $ — $ 2,152 December 31, 2016 Level 1 Level 2 Level 3 Total Assets: (In thousands) Government-sponsored mortgage-backed securities $ — $ 180,136 $ — $ 180,136 U.S. government guaranteed mortgage-backed securities — 17,350 — 17,350 Corporate bonds — 50,317 — 50,317 State and municipal bonds — 4,008 — 4,008 Government-sponsored enterprise obligations — 42,008 — 42,008 Mutual funds 6,296 — — 6,296 Total assets $ 6,296 $ 293,819 $ — $ 300,115 Liabilities: Interest rate swaps $ — $ 3,152 $ — $ 3,152 There were no transfers to or from Level 1 and 2 for assets measured at fair value on a recurring basis during the years ended December 31, 2017 and 2016. Assets Measured at Fair Value on a Non-recurring Basis We may also be required, from time to time, to measure certain other financial assets at fair value on a nonrecurring basis in accordance with generally accepted accounting principles. These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets. The following table summarizes the fair value hierarchy used to determine the carrying values of the related assets as of December 31, 2017 and 2016. At Year Ended December 31, 2017 December 31, 2017 Total Level 1 Level 2 Level 3 Losses (In thousands) (In thousands) Impaired Loans $ — $ — $ 1,495 $ 256 At Year Ended December 31, 2016 December 31, 2016 Total Level 1 Level 2 Level 3 Losses (In thousands) (In thousands) Impaired Loans $ — $ — $ 2,143 $ 230 The amount of impaired loans represents the carrying value, and net of the related write-down or valuation allowance of impaired loans for which adjustments are based on the estimated fair value of the underlying collateral. The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on real estate appraisals performed by independent licensed or certified appraisers. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Management will discount appraisals as deemed necessary based on the date of the appraisal and new information deemed relevant to the valuation. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. The resulting losses were recognized in earnings through the provision for loan losses. There were no liabilities measured at fair value on a non-recurring basis at December 31, 2017 and 2016.

Segment Reporting [Abstract]
SEGMENT INFORMATION	18. SEGMENT INFORMATION We have one reportable segment, “Community Banking.” All of our activities are interrelated, and each activity is dependent and assessed based on how each of the activities supports the others. For example, commercial lending is dependent upon the ability of the Bank to fund itself with retail deposits and other borrowings and to manage interest rate and credit risk. This situation is also similar for consumer and residential mortgage lending. Accordingly, all significant operating decisions are based upon our analysis as one operating segment or unit. We operate only in the U.S. domestic market, primarily in western Massachusetts and northern Connecticut. For the years ended December 31, 2017, 2016 and 2015, there is no customer that accounted for more than 10% of our revenue.

Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation The Bank’s deposits are insured to the limits specified by the Federal Deposit Insurance Corporation (“FDIC”). The Bank operates 21 banking offices in western Massachusetts and northern Connecticut, and its primary sources of revenue are earnings on loans to small and middle-market businesses and to residential property homeowners and income from securities.
Wholly-Owned Subsidiaries and Acquisition	Wholly-Owned Subsidiaries and Acquisition On October 21, 2016, we acquired Chicopee Bancorp, Inc. (“Chicopee”), the holding company for Chicopee Savings Bank. The acquisition added eight full-service banking offices located in western Massachusetts. The primary purpose of the acquisition with Chicopee was to expand our presence in western Massachusetts and diversify our market area. The transaction qualified as a tax-free reorganization for federal income tax purposes. Merger consideration paid in the transaction to shareholders of Chicopee totaled $98.8 million, consisting of 11,919,412 shares of Company common stock, net of shares of Chicopee already owned, and shares of Chicopee’s ESOP liquidated to payoff the ESOP loan. We accounted for the transaction using the acquisition method. Accordingly, we recorded acquisition expenses totaling $526,000 and $4.1 million (pre-tax) during 2017 and 2016, respectively. The acquisition method requires an acquirer to recognize the assets acquired and the liabilities assumed at fair value as of the acquisition date. Additionally, our results of operations include Chicopee’s operating results from the date of acquisition.

Fair Value Hierarchy	Fair Value Hierarchy Level 1 – Valuation is based on quoted prices in active markets for identical assets. Level 1 assets generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets. Level 2 – Valuation is based on observable inputs other than Level 1 prices, such as quoted prices for similar assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets and liabilities. Level 3 – Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. Level 3 assets include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Transfers between levels are recognized at the end of a reporting period, if applicable.

Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is evaluated on a regular basis by management. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of general, allocated and unallocated components, as further described below. General component The general component of the allowance for loan losses is based on historical loss experience adjusted for qualitative factors stratified by the following loan segments: residential real estate, commercial real estate, commercial and industrial, and consumer. Residential real estate loans include classes for residential and home equity. Management uses a rolling average of historical losses based on a time frame appropriate to capture relevant loss data for each loan segment. This historical loss factor is adjusted for the following qualitative factors: trends in delinquencies and nonperforming loans; trends in volume and terms of loans; internal credit ratings; effects of changes in risk selection; underwriting standards and other changes in lending policies, procedures and practices; and national and local economic trends and industry conditions. There were no changes in our policies or methodology pertaining to the general component of the allowance for loan losses during 2017. 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: Commercial real estate – Loans in this segment are primarily income-producing investment properties and owner occupied commercial properties throughout New England. The underlying cash flows generated by the properties or operations can be adversely impacted by a downturn in the economy due to increased vacancy rates or diminished cash flows, which in turn, would have an effect on the credit quality in this segment. Management obtains financial information annually and continually monitors the cash flows of these loans. Residential real estate –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. We require private mortgage insurance for all loans originated with a loan-to-value ratio greater than 80 percent and do not grant subprime loans. Commercial and industrial 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, decreased consumer spending, changes in technology and government spending are examples of what will have an effect on the credit quality in this segment. Consumer loans – Loans in this segment are both secured and unsecured and repayment is dependent on the credit quality of the individual borrower. Allocated component The allocated component relates to loans that are classified as impaired. Impaired loans are identified by analysis of loan performance, internal credit ratings and watch list loans that management believes are subject to a higher risk of loss. Impairment is measured on a loan by loan basis for commercial real estate and commercial and industrial loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. An allowance is established when the discounted cash flows (or collateral value) of the impaired loan is lower than the carrying value of that loan. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, we do not separately identify individual consumer and residential real estate loans for impairment disclosures, unless such loans are nonperforming or subject to a troubled debt restructuring agreement. A loan is considered impaired when, based on current information and events, it is probable that we will be unable to collect all of the 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. We determine 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. We may periodically 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 classified as impaired. While we use our best judgment and information available, the ultimate appropriateness of the allowance is dependent upon a variety of factors beyond our control, including the performance of our loan portfolio, the economy, changes in interest rates and the view of the regulatory authorities toward loan classifications. Unallocated component An unallocated component may be maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating allocated and general reserves in the portfolio.

Servicing	Servicing Servicing fee income is recorded for fees earned for servicing loans, which is included in service charges and fee income. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned.
Impairment of Long-lived Assets	Impairment of Long-lived Assets Goodwill is measured as the excess of the cost of a business combination over the sum of the amounts assigned to identifiable intangible assets acquired less liabilities assumed. Goodwill is not amortized but rather assessed for impairment annually or more frequently if circumstances warrant. Management has the option of first assessing qualitative factors, such as events and circumstances, to determine whether it is more likely than not, meaning a likelihood of more than 50%, the value of a reporting unit is less than its carrying amount. If, after considering all relevant events and circumstances, management determines it is not more likely than not the fair value of a reporting unit is less than its carrying amount, then performing an impairment test is unnecessary. For the year ended December 31, 2017, management determined that it was not more likely than not the fair value of the reporting unit (the consolidated Company, in our case) was less than its carrying amount. If management had determined otherwise, a fair value analysis would have been completed to determine the impairment and necessary write-down of goodwill.
