NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. Nature of Operations and Summary of Significant Accounting Policies Bankwell Financial Group, Inc. (the “Company” or “Bankwell”) is a bank holding company headquartered in New Canaan, Connecticut. The Company offers a broad range of financial services through its banking subsidiary, Bankwell Bank (the “Bank”). The Bank is a Connecticut state chartered commercial bank, founded in 2002, whose deposits are insured under the Deposit Insurance Fund administered by the Federal Deposit Insurance Corporation (“FDIC”). The Bank provides a full range of banking services to commercial and consumer customers, primarily concentrated in the New York metropolitan area and throughout Connecticut, with the majority of our loans in Fairfield and New Haven Counties, Connecticut, with branch locations in New Canaan, Stamford, Fairfield, Wilton, Norwalk, Hamden and North Haven Connecticut. Many of the Company’s activities are with customers located in the New York Metropolitan area and throughout Fairfield and New Haven Counties and the surrounding region of Connecticut, and declines in property values in these areas could significantly impact the Company. The Company has significant concentrations in commercial real estate loans. Management does not believe they present any special risk. The Company does not have any significant concentrations in any one industry or customer. Principles of consolidation The consolidated financial statements include the accounts of the Company and the Bank, including its wholly owned passive investment company subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of estimates The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America (“GAAP”) and general practices within the banking industry. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities as of the date of the consolidated balance sheet and revenue and expenses for the period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the allowance for loan losses, stock-based compensation, derivative instrument valuation, investment securities valuation, evaluation of investment securities for other than temporary impairment and deferred income taxes valuation. Basis of consolidated financial statement presentation The unaudited consolidated financial statements presented herein have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and Rule 10-1 of Regulation S-X and do not include all of the information and note disclosures required by GAAP. In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures considered necessary for the fair presentation of the accompanying unaudited interim consolidated financial statements have been included. Interim results are not necessarily reflective of the results that may be expected for the year ending December 31, 2018. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included on Form 10-K for the year ended December 31, 2017. Significant concentrations of credit risk Most of the Company's activities are with customers located within the New York metropolitan area and throughout Connecticut, with the majority of our loans in the Fairfield and New Haven County regions of Connecticut, and declines in property values in these areas could significantly impact the Company. The Company has significant concentrations in commercial real estate loans. Management does not believe they present any special risk. The Company does not have any significant concentrations in any one industry or customer. Reclassification Certain prior period amounts have been reclassified to conform to the 2018 financial statement presentation. These reclassifications only changed the reporting categories and did not affect the consolidated results of operations or consolidated financial position.

Total sales proceeds were $7.7 million for the three months ended March 31, 2018.

There were no gross realized losses on the sale of investment securities for the three months ended March 31, 2017. Total sales proceeds were $49.6 million for the three months ended March 31, 2017. At March 31, 2018 and December 31, 2017 there were no securities pledged as collateral with the Federal Home Loan Bank (FHLB). The following table provides information regarding investment securities with unrealized losses, aggregated by investment category and length of time that individual securities had been in a continuous unrealized loss position at March 31, 2018 and December 31, 2017: Length of Time in Continuous Unrealized Loss Position Less Than 12 Months 12 Months or More Total Fair Value Unrealized Percent Fair Value Unrealized Percent Fair Value Unrealized Percent (In thousands) March 31, 2018 U.S. Government and agency obligations $ 77,383 $ (1,587 ) 2.01 % $ 2,054 $ (45 ) 2.17 % $ 79,437 $ (1,632 ) 2.01 % State agency and municipal obligations 11,691 (190 ) 1.60 % 590 (42 ) 6.64 % 12,281 (232 ) 1.86 % Corporate bonds 7,031 (56 ) 0.79 % 995 (5 ) 0.50 % 8,026 (61 ) 0.75 % Total investment securities $ 96,105 $ (1,833 ) 1.87 % $ 3,639 $ (92 ) 2.48 % $ 99,744 $ (1,925 ) 1.89 % December 31, 2017 U.S. Government and agency obligations $ 70,419 $ (225 ) 0.32 % $ 2,064 $ (35 ) 1.67 % $ 72,483 $ (260 ) 0.36 % State agency and municipal obligations 92 - 0.16 % 656 (27 ) 3.95 % 748 (27 ) 3.50 % Corporate bonds - - - 995 (5 ) 0.50 % 995 (5 ) 0.50 % Total investment securities $ 70,511 $ (225 ) 0.32 % $ 3,715 $ (67 ) 1.77 % $ 74,226 $ (292 ) 0.39 % There were twenty-six and fifteen investment securities as of March 31, 2018 and December 31, 2017, respectively, in which the fair value of the security was less than the amortized cost of the security. The U.S. Government and agency obligations owned are either direct obligations of the U.S. Government or guaranteed by the U.S. Government, therefore the contractual cash flows are guaranteed and as a result the unrealized losses in this portfolio are not considered other than temporarily impaired. The Company continually monitors its state agency, municipal and corporate bond portfolios and at this time these portfolios have minimal default risk because state agency, municipal and corporate bonds are all rated investment grade or deemed to be of investment grade quality. The Company has the intent and ability to retain its investment securities in an unrealized loss position at March 31, 2018 until the decline in value has recovered.

LOANS RECEIVABLE AND ALLOWANCE FOR LOAN LOSSES	3. Loans Receivable and Allowance for Loan Losses The following table sets forth a summary of the loan portfolio at March 31, 2018 and December 31, 2017: (In thousands) March 31, 2018 December 31, 2017 Real estate loans: Residential $ 195,638 $ 193,524 Commercial 1,005,962 987,242 Construction 87,309 101,636 1,288,909 1,282,402 Commercial business 267,052 259,995 Consumer 446 619 Total loans 1,556,407 1,543,016 Allowance for loan losses (18,801 ) (18,904 ) Deferred loan origination fees, net (3,050 ) (3,242 ) Unamortized loan premiums 9 9 Loans receivable, net $ 1,534,565 $ 1,520,879 Lending activities are conducted principally in the New York metropolitan area, including the Fairfield and New Haven County regions of Connecticut, and consist of residential and commercial real estate loans, commercial business loans and a variety of consumer loans. Loans may also be granted for the construction of residential homes and commercial properties. The majority of residential and commercial mortgage loans are collateralized by first or second mortgages on real estate. Risk management The Company has established credit policies applicable to each type of lending activity in which it engages. The Company evaluates the creditworthiness of each customer and extends credit of up to 80% of the market value of the collateral, depending on the borrowers’ creditworthiness and the type of collateral. The borrower’s ability to service the debt is monitored on an ongoing basis. Real estate is the primary form of collateral. Other important forms of collateral are business assets, time deposits and marketable securities. While collateral provides assurance as a secondary source of repayment, the Company ordinarily requires the primary source of repayment for commercial loans, to be based on the borrower’s ability to generate continuing cash flows. In the fourth quarter of 2017 management made the strategic decision to no longer originate residential mortgage loans. The Company’s policy for residential lending allowed that, generally, the amount of the loan may not exceed 80% of the original appraised value of the property. In certain situations, the amount may have exceeded 80% LTV either with private mortgage insurance being required for that portion of the residential loan in excess of 80% of the appraised value of the property or where secondary financing is provided by a housing authority program second mortgage, a community’s low/moderate income housing program, or a religious or civic organization. Credit quality of loans and the allowance for loan losses Management segregates the loan portfolio into portfolio segments which is defined as the level at which the develops and documents a systematic method for determining its allowance for loan losses. The portfolio segments are segregated based on loan types and the underlying risk factors present in each loan type. Such risk factors are periodically reviewed by management and revised as deemed appropriate. The Company's loan portfolio is segregated into the following portfolio segments: Residential Real Estate: Commercial Real Estate: Construction: Commercial Business: Consumer: Allowance for loan losses As of December 31, 2017 the Company has changed its methodology to estimate its allowance for loan losses. The change in methodology resulted in an update to the underlying loan loss assumptions, incorporating the most recent industry, peer and product loss trends. This resulted in a non-recurring, pretax $1.3 million reduction in the reserve for the year ended December 31, 2017. The following tables set forth the activity in the Company’s allowance for loan losses for the three months ended March 31, 2018 and 2017, by portfolio segment: Residential Commercial Commercial Real Estate Real Estate Construction Business Consumer Total (In thousands) March 31, 2018 Beginning balance $ 1,721 $ 12,777 $ 907 $ 3,498 $ 1 $ 18,904 Charge-offs - (18 ) - (96 ) (3 ) (117 ) Recoveries - - - - 1 1 (Credits) Provisions (26 ) (114 ) (140 ) 290 3 13 Ending balance $ 1,695 $ 12,645 $ 767 $ 3,692 $ 2 $ 18,801 Residential Commercial Commercial Real Estate Real Estate Construction Business Consumer Total (In thousands) March 31, 2017 Beginning balance $ 1,654 $ 9,563 $ 2,105 $ 4,283 $ 377 $ 17,982 Charge-offs - - - - (15 ) (15 ) Recoveries - - - - 1 1 (Credits) Provisions (7 ) (14 ) 17 538 9 543 Ending balance $ 1,647 $ 9,549 $ 2,122 $ 4,821 $ 372 $ 18,511 Loans evaluated for impairment and the related allowance for loan losses as of March 31, 2018 and December 31, 2017 were as follows: Portfolio Allowance (In thousands) March 31, 2018 Loans individually evaluated for impairment: Residential real estate $ 7,202 $ 14 Commercial real estate 22,100 708 Construction 1,546 2 Commercial business 3,381 45 Consumer 6 - Subtotal 34,235 769 Loans collectively evaluated for impairment: Residential real estate 188,436 1,681 Commercial real estate 983,862 11,937 Construction 85,763 765 Commercial business 263,671 3,647 Consumer 440 2 Subtotal 1,522,172 18,032 Total $ 1,556,407 $ 18,801 Portfolio Allowance (In thousands) December 31, 2017 Loans individually evaluated for impairment: Residential real estate $ 4,607 $ 8 Commercial real estate 7,586 876 Commercial business 2,660 71 Subtotal 14,853 955 Loans collectively evaluated for impairment: Residential real estate 188,917 1,713 Commercial real estate 979,656 11,901 Construction 101,636 907 Commercial business 257,335 3,427 Consumer 619 1 Subtotal 1,528,163 17,949 Total $ 1,543,016 $ 18,904 Credit quality indicators To measure credit risk for the loan portfolios, the Company employs a credit risk rating system. This risk rating represents an assessed level of the loan’s risk based on the character and creditworthiness of the borrower/guarantor, the capacity of the borrower to adequately service the debt, any credit enhancements or additional sources of repayment, and the quality, value and coverage of the collateral, if any. The objectives of the Company’s risk rating system are to provide the Board of Directors and senior management with an objective assessment of the overall quality of the loan portfolio, to promptly and accurately identify loans with well-defined credit weaknesses so that timely action can be taken to minimize credit loss, to identify relevant trends affecting the collectability of the loan portfolio and to isolate potential problem areas and to provide essential information for determining the adequacy of the allowance for loan losses. The Company’s credit risk rating system has nine grades, with each grade corresponding to a progressively greater risk of default. Risk ratings of 1 through 5 are Pass categories and risk ratings of 6 through 9 are criticized asset categories as defined by the regulatory agencies. A “Special Mention” (6) credit has a potential weakness which, if uncorrected, may result in a deterioration of the repayment prospects or inadequately protect the Company’s credit position at some time in the future. “Substandard” loans (7) are credits that have a well-defined weakness or weaknesses that jeopardize the full repayment of the debt. An asset rated “Doubtful” (8) has all the weaknesses inherent in a substandard asset and which, in addition, make collection or liquidation in full highly questionable and improbable, when considering existing facts, conditions, and values. Loans classified as “Loss” (9) are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value; rather, it is not practical or desirable to defer writing-off this basically worthless asset even though partial recovery may be made in the future. Risk ratings are assigned as necessary to differentiate risk within the portfolio. They are reviewed on an ongoing basis through the annual loan review process performed by Company personnel, normal renewal activity and the quarterly watchlist and watched asset report process. They are revised to reflect changes in the borrowers’ financial condition and outlook, debt service coverage capability, repayment performance, collateral value and coverage as well as other considerations. In addition to internal review at multiple points, outsourced loan review opines on risk ratings with regard to the sample of loans their review covers.

The Company also contacts the borrower by phone if the delinquency is not corrected promptly after the notice has been sent. When the loan is 30 days past due, the Company mails the borrower a letter reminding the borrower of the delinquency, and attempts to contact the borrower personally to determine the reason for the delinquency and ensure the borrower understands the terms of the loan. If necessary, on the subsequent 90th day of delinquency, the Company may take other appropriate legal action. A summary report of all loans 30 days or more past due is provided to the Board of Directors of the Company each month. Loans greater than 90 days past due are generally put on nonaccrual status. A nonaccrual loan is restored to accrual status when it is no longer delinquent and collectability of interest and principal is no longer in doubt. A loan is considered to be no longer delinquent when timely payments are made for a period of at least six months (one year for loans providing for quarterly or semi-annual payments) by the borrower in accordance with the contractual terms.

Impaired loans An impaired loan generally is one for which it is probable, based on current information, the Company will not collect all the amounts due in accordance with the contractual terms of the loan. Loans are individually evaluated for impairment. When the Company classifies a problem loan as impaired, it provides a specific valuation allowance for that portion of the asset that is estimated to be impaired.

Modified terms are dependent upon the financial position and needs of the individual borrower. Troubled debt restructurings are classified as impaired loans. If a performing loan is restructured into a TDR it remains in performing status. If a nonperforming loan is restructured into a TDR, it continues to be carried in nonaccrual status. Nonaccrual classification may be removed if the borrower demonstrates compliance with the modified terms for a minimum of six months. Loans classified as TDRs totaled $7.5 million at March 31, 2018 and $4.9 million at December 31, 2017. There were no loans modified as TDRs during the three months ended March 31, 2017.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	6. Earnings per Share Unvested restricted stock awards that contain non-forfeitable rights to dividends, are participating securities, and are included in the computation of EPS pursuant to the two-class method. The two-class method is an earnings allocation formula that determines EPS for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. The Company’s unvested restricted stock awards qualify as participating securities. Net income is allocated between the common stock and participating securities pursuant to the two-class method. Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period, excluding participating unvested restricted stock awards. Diluted EPS is computed in a similar manner, except that the denominator includes the number of additional common shares that would have been outstanding if potentially dilutive common shares were issued using the treasury stock method. The following is a reconciliation of earnings available to common shareholders and basic weighted average common shares outstanding to diluted weighted average common shares outstanding, reflecting the application of the two-class method: Three Months Ended March 31, 2018 2017 (In thousands, except per share data) Net income $ 4,600 $ 3,702 Dividends to participating securities (1) (13 ) (7 ) Undistributed earnings allocated to participating securities (1) (46 ) (43 ) Net income for earnings per share calculation $ 4,541 $ 3,652 Weighted average shares outstanding, basic 7,677 7,525 Effect of dilutive equity-based awards (2) 45 107 Weighted average shares outstanding, diluted 7,722 7,632 Net earnings per common share: Basic earnings per common share $ 0.59 $ 0.49 Diluted earnings per common share $ 0.59 $ 0.48 (1) Represents dividends paid and undistributed earnings allocated to unvested stock-based awards that contain non-forfeitable rights to dividends. (2) Represents the effect of the assumed exercise of stock options and the vesting of restricted shares, as applicable, utilizing the treasury stock method.

Regulatory Matters

Regulatory Matters	3 Months Ended

Banking and Thrift [Abstract]
REGULATORY MATTERS	7. Regulatory Matters The Federal Reserve, the FDIC and the other federal and state bank regulatory agencies establish regulatory capital guidelines for U.S. banking organizations. As of January 1, 2015, the Company and the Bank became subject to new capital rules set forth by the Federal Reserve, the FDIC and the other federal and state bank regulatory agencies. The capital rules revise the banking agencies’ leverage and risk-based capital requirements and the method for calculating risk weighted assets to make them consistent with agreements that were reached by the Basel Committee on Banking Supervision and certain provisions of the Dodd-Frank Act (the Basel III Capital Rules). The Basel III Capital Rules establish a minimum common equity Tier 1 capital requirement of 4.5% of risk-weighted assets; set the minimum leverage ratio at 4% of total assets; increased the minimum Tier 1 capital to risk-weighted assets requirement from 4% to 6%; and retained the minimum total capital to risk weighted assets requirement at 8.0%. A “well-capitalized” institution must generally maintain capital ratios 100-200 basis points higher than the minimum guidelines. The Basel III Capital Rules also change the risk weights assigned to certain assets. The Basel III Capital Rules assigned a higher risk weight (150%) to loans that are more than 90 days past due or are on nonaccrual status and to certain commercial real estate facilities that finance the acquisition, development or construction of real property. The Basel III Capital Rules also alter the risk weighting for other assets, including marketable equity securities that are risk weighted generally at 300%. The Basel III Capital Rules require certain components of accumulated other comprehensive income (loss) to be included for purposes of calculating regulatory capital requirements unless a one-time opt-out is exercised. The Bank did exercise its opt-out option and will exclude the unrealized gain (loss) on investment securities component of accumulated other comprehensive income (loss) from regulatory capital. The Basel III Capital Rules limit a banking organization’s capital distributions and certain discretionary bonus payments to executive officers if the banking organization does not hold a “capital conservation buffer” consisting of 2.5% of regulatory risk based capital ratios in addition to the amount necessary to meet its minimum risk-based capital requirements. The required minimum conservation buffer began to be phased in incrementally, starting at 0.625% on January 1, 2016, increased to 1.25% on January 1, 2017, increased to 1.875% on January 1, 2018 and will continue to increase to 2.5% on January 1, 2019. 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 the Company’s consolidated financial statements. As of March 31, 2018, the Bank and Company has met all capital adequacy requirements to which they are subject. There are no conditions or events since then that management believes have changed this conclusion. The capital amounts and ratios for the Bank and the Company at March 31, 2018 and December 31, 2017 were as follows: Minimum Regulatory Minimum Regulatory Capital Required for Capital to be Well Capital Adequacy Capitalized Under plus Capital Prompt Corrective Actual Capital Conservation Buffer Action Provisions (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio Bankwell Bank March 31, 2018 Common Equity Tier 1 Capital to Risk-Weighted Assets $ 179,579 11.18 % $ 102,425 6.38 % $ 104,433 6.50 % Total Capital to Risk-Weighted Assets 198,380 12.35 % 158,658 9.88 % 160,667 10.00 % Tier I Capital to Risk-Weighted Assets 179,579 11.18 % 126,525 7.88 % 128,533 8.00 % Tier I Capital to Average Assets 179,579 9.90 % 72,547 4.00 % 90,683 5.00 % Bankwell Financial Group, Inc.

The Bank is also prohibited from paying dividends that would reduce its capital ratios below minimum regulatory requirements. Reserve Requirements on Cash The Bank is required to maintain a minimum reserve balance of $10.7 million and $11.1 million in the Federal Reserve Bank at March 31, 2018 and December 31, 2017, respectively. The Bank is also required to maintain a minimum reserve balance of $7.5 million at Atlantic Community Bankers Bank (formerly Bankers’ Bank Northeast) at March 31, 2018 and December 31, 2017. These balances are maintained for clearing purposes in the ordinary course of business and do not represent restricted cash.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	9. Derivative Instruments The Company manages economic risks, including interest rate, liquidity, and credit risk by managing the amount, sources, and duration of its funding along with the use of interest rate derivative financial instruments, namely interest rate swaps. The Company does not use derivatives for speculative purposes. As of March 31, 2018, the Bank was a party to six interest rate swaps to add stability to interest expense and to manage its exposure to interest rate movements. The notional amount for each swap is $25 million and in each case, the Bank has entered into pay-fixed Libor interest rate swaps to convert rolling 90 day Federal Home Loan Bank advances to fixed rates. The Company accounts for its interest rate swaps as effective cash flow hedges. None of the interest rate swap agreements contain any credit risk related contingent features. A hedging instrument is expected at inception to be highly effective at offsetting changes in the hedged transactions attributable to the changes in the hedged risk. Interest Rate Swaps with a positive fair value are recorded as other assets and interest rate swaps with a negative fair value are recorded as other liabilities on the consolidated balance sheets. Information about derivative instruments at March 31, 2018 and December 31, 2017 is as follows: March 31, 2018: (Dollars in thousands) Notional Original Received Paid Fair Value Cash flow hedge: Interest rate swap on FHLB advance $ 25,000 4.7 years 3-month LIBOR 1.62% $ 135 Interest rate swap on FHLB advance 25,000 5.0 years 3-month LIBOR 1.83% 291 Interest rate swap on FHLB advance 25,000 5.0 years 3-month LIBOR 1.48% 626 Interest rate swap on FHLB advance 25,000 5.0 years 3-month LIBOR 1.22% 1,099 Interest rate swap on FHLB advance 25,000 7.0 years 3-month LIBOR 2.04% 947 Interest rate swap on FHLB advance 25,000 7.0 years 3-month LIBOR 2.04% 939 $ 150,000 $ 4,037 December 31, 2017: (Dollars in thousands) Notional Original Received Paid Fair Value Cash flow hedge: Interest rate swap on FHLB advance $ 25,000 4.7 years 3-month LIBOR 1.62% $ 62 Interest rate swap on FHLB advance 25,000 5.0 years 3-month LIBOR 1.83% 105 Interest rate swap on FHLB advance 25,000 5.0 years 3-month LIBOR 1.48% 398 Interest rate swap on FHLB advance 25,000 5.0 years 3-month LIBOR 1.22% 793 Interest rate swap on FHLB advance 25,000 7.0 years 3-month LIBOR 2.04% 342 Interest rate swap on FHLB advance 25,000 7.0 years 3-month LIBOR 2.04% 334 $ 150,000 $ 2,034 The effective portion of unrealized changes in the fair value of derivatives accounted for as cash flow hedges is reported in other comprehensive income and subsequently reclassified to earnings in the same period or periods during which the hedged forecasted transaction affects earnings. The Company assesses 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 item or transaction. The ineffective portion of changes in the fair value of the derivatives is recognized directly in earnings. The interest rate swap assets are presented in other assets and the interest rate swap liabilities are presented in accrued expenses and other liabilities in the consolidated balance sheets. The Company's cash flow hedge positions consist of interest rate swap transactions as detailed in the table below: (Dollars in thousands) Notional Original Effective Duration of Counterparty Type of borrowing: FHLB 90-day advance $ 25,000 April 1, 2014 4.7 years Bank of Montreal FHLB 90-day advance 25,000 January 2, 2015 5.0 years Bank of Montreal FHLB 90-day advance 25,000 August 26, 2015 5.0 years Bank of Montreal FHLB 90-day advance 25,000 July 1, 2016 5.0 years Bank of Montreal FHLB 90-day advance 25,000 August 25, 2017 7.0 years Bank of Montreal FHLB 90-day advance 25,000 August 25, 2017 7.0 years FTN Financial Capital Markets $ 150,000 This hedge strategy converts the floating rate of interest on short term FHLB advances to fixed interest rates, thereby protecting the Bank from floating interest rate variability.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	10. Fair Value of Financial Instruments GAAP requires disclosure of fair value information about financial instruments, whether or not recognized in the statements of condition, for which it is practicable to estimate that value. 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 rates and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparisons to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent limitations in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates presented herein are not necessarily indicative of the amounts the Company could have realized in a sales transaction. The estimated fair value amounts have been measured as of the respective period-ends, and have not been reevaluated or updated for purposes of these consolidated financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period-end. The Company assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations. As a result, the fair values of the Company’s financial instruments will change when interest rate levels change and that change may be either favorable or unfavorable to the Company. Management attempts to match maturities of assets and liabilities to the extent believed necessary to minimize interest rate risk. However, borrowers with fixed rate obligations are less likely to prepay in a rising rate environment and more likely to prepay in a falling rate environment. Conversely, depositors who are receiving fixed rates are more likely to withdraw funds before maturity in a rising rate environment and less likely to do so in a falling rate environment. Management monitors rates and maturities of assets and liabilities and attempts to minimize interest rate risk. The carrying values, fair values and placement in the fair value hierarchy of the Company's financial instruments at March 31, 2018 and December 31, 2017 were as follows: March 31, 2018 Carrying Fair Value Value Level 1 Level 2 Level 3 (In thousands) Financial Assets: Cash and due from banks $ 81,249 $ 81,249 $ 81,249 $ - $ - Federal funds sold 2,121 2,121 2,121 - - Available for sale securities 99,050 99,050 - 99,050 - Held to maturity securities 21,546 22,021 - 1,110 20,911 Loans receivable, net 1,534,565 1,477,811 - - 1,477,811 Accrued interest receivable 5,331 5,331 - 5,331 - FHLB stock 9,310 9,310 - 9,310 - Servicing asset 1,147 1,147 - - 1,147 Derivative asset 4,037 4,037 - 4,037 - Financial Liabilities: Demand deposits $ 161,641 $ 161,641 $ - $ 161,641 $ - NOW and money market 537,940 537,940 - 537,940 - Savings 96,664 96,664 - 96,664 - Time deposits 630,282 627,169 - - 627,169 Accrued interest payable 1,037 1,037 - 1,037 - Advances from the FHLB 199,000 198,683 - - 198,683 Subordinated debentures 25,116 24,824 - - 24,824 Servicing liability 80 80 - - 80 December 31, 2017 Carrying Fair Value Value Level 1 Level 2 Level 3 (In thousands) Financial Assets: Cash and due from banks $ 70,545 $ 70,545 $ 70,545 $ - $ - Federal funds sold 186 186 186 - - Available for sale securities 92,188 92,188 - 92,188 - Held to maturity securities 21,579 22,836 - 1,119 21,717 Loans receivable, net 1,520,879 1,494,599 - - 1,494,599 Accrued interest receivable 5,910 5,910 - 5,910 - FHLB stock 9,183 9,183 - 9,183 - Servicing asset 1,113 1,113 - - 1,113 Derivative asset, net 2,034 2,034 - 2,034 - Financial Liabilities: Demand deposits $ 172,638 $ 172,638 $ - $ 172,638 $ - NOW and money market 510,746 510,746 - 510,746 - Savings 83,758 83,758 - 83,758 - Time deposits 631,263 629,532 - - 629,532 Accrued interest payable 1,092 1,092 - 1,092 - Advances from the FHLB 199,000 198,932 - - 198,932 Subordinated debentures 25,103 25,547 - - 25,547 Servicing Liability 83 83 - - 83 The following methods and assumptions were used by management in estimating the fair value of its financial instruments: Cash and due from banks, federal funds sold, accrued interest receivable and accrued interest payable: Available for sale and held to maturity securities: FHLB stock: Loans receivable: Derivative asset (liability): Servicing asset (liability): Deposits: Borrowings and Subordinated Debentures: Off-balance-sheet instruments:

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	11. Fair Value Measurements The Company is required to account for certain assets at fair value on a recurring or non-recurring basis. The Company determines fair value in accordance with GAAP, which defines fair value and establishes a framework for measuring fair value. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. GAAP establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair values: Level 1 — Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2 — Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 — Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Valuation techniques based on unobservable inputs are highly subjective and require judgments regarding significant matters such as the amount and timing of future cash flows and the selection of discount rates that may appropriately reflect market and credit risks. Changes in these judgments often have a material impact on the fair value estimates. In addition, since these estimates are as of a specific point in time they are susceptible to material near-term changes. Financial instruments measured at fair value on a recurring basis The following tables detail the financial instruments carried at fair value on a recurring basis at March 31, 2018 and December 31, 2017, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine the fair value. The Company had no transfers into or out of Levels 1, 2 or 3 during the three months ended March 31, 2018 and the year ended December 31, 2017.

The following table details the financial instruments measured at fair value on a nonrecurring basis at March 31, 2018 and December 31, 2017, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine the fair value: Fair Value (In thousands) Level 1 Level 2 Level 3 March 31, 2018: Impaired loans $ - $ - $ 33,466 Foreclosed real estate - - 487 Servicing asset, net - - 1,067 December 31, 2017: Impaired loans $ - $ - $ 13,898 Servicing asset, net - - 1,030 The following table presents information about quantitative inputs and assumptions for Level 3 financial instruments carried at fair value on a nonrecurring basis at March 31, 2018 and December 31, 2017: (Dollars in thousands) Valuation Unobservable Input Range March 31, 2018: Impaired loans Appraisals Discount to appraised value 8.00 - 30.00% Discounted cash flows Discount rate 3.25 - 7.25% Foreclosed real estate Appraisals Discount to appraised value 8.00% Servicing asset, net Discounted cash flows Discount rate 7.00 - 12.00% Prepayment rate 7.00 - 9.00% December 31, 2017: Impaired loans Appraisals Discount to appraised value 8.00 - 24.00% Discounted cash flows Discount rate 3.25 - 6.75% Servicing asset, net Discounted cash flows Discount rate 7.00 - 12.00% Prepayment rate 7.00 - 9.00% Impaired loans Foreclosed real estate: Servicing assets and liabilities:

Subordinated debentures On August 19, 2015 the Company completed a private placement of $25.5 million in aggregate principal amount of fixed rate subordinated notes (the “Notes”) to certain institutional investors. The Notes are non-callable for five years, have a stated maturity of August 15, 2025, and bear interest at a quarterly pay fixed rate of 5.75% per annum to the maturity date or the early redemption date. The Notes have been structured to qualify for the Company as Tier 2 capital under regulatory guidelines. We used the net proceeds for general corporate purposes, which included maintaining liquidity at the holding company, providing equity capital to the Bank to fund balance sheet growth and our working capital needs. The Notes were assigned an investment grade rating of BBB by Kroll Bond Rating Agency, which was reaffirmed in the third quarter of 2017.

Income taxes	13. Income Taxes The Company is subject to federal and state income taxes at the statutory rates and makes several adjustments to arrive at the effective tax rate. The Company adjusts for non-deductible meals and entertainment, interest earned on municipal bonds, income earned on our investment in bank owned life insurance, windfall tax benefits resulting from restricted stock vesting and reductions in Connecticut state income tax from the establishment of a passive investment company. Income tax expense for the three months ended March 31, 2018 and 2017 totaled $1.2 million and $1.7 million, respectively. The effective tax rates for the three months ended March 31, 2018 and 2017 were 21.0%, and 31.9%, respectively. The decrease in the effective tax rate for the three months ended March 31, 2018 is driven by a reduction in the corporate tax rate from 35% to 21% as a result of tax reform coming from the Tax Cuts and Jobs Act of 2017.
