Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Organization and Business First Connecticut Bancorp, Inc. is a Maryland-chartered bank holding company that wholly owns its only subsidiary, Farmington Bank (collectively with its subsidiary, the “Company”). Farmington Bank's main office is located in Farmington, Connecticut. Farmington Bank is a full-service, community bank with 24 branch locations throughout central Connecticut and western Massachusetts, offering commercial and residential lending as well as wealth management services. Farmington Bank's primary source of income is interest accrued on loans to customers, which include small and middle market businesses and individuals residing primarily in Connecticut and western Massachusetts. However, the Bank will selectively lend to borrowers in other northeastern states. Wholly-owned subsidiaries of Farmington Bank are Farmington Savings Loan Servicing, Inc., a passive investment company that was established to service and hold loans collateralized by real property; Village Investments, Inc.; the Village Corp., Limited, and Village Square Holdings, Inc.; 28 Main Street Corp., is a subsidiary that was formed to hold residential other real estate owned and Village Management Corp., is a subsidiary that was formed to hold commercial other real estate owned, are presently inactive. On June 21, 2013, the Company received regulatory approval to repurchase up to 1,676,452 shares, or 10% of its current outstanding common stock. During the year ended December 31, 2016, the Company had repurchased 156,800 of these shares at a cost of $2.5 million. Repurchased shares are held as treasury stock and are available for general corporate purposes. The Company has 600,945 shares remaining available to be repurchased at December 31, 2016. Basis of Financial Statement Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. The consolidated financial statements include the accounts of First Connecticut Bancorp, Inc. and its wholly-owned subsidiary, Farmington Bank. All significant intercompany transactions and balances have been eliminated in consolidation. In preparing the consolidated financial statements, management is required to make extensive use of estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the statement of condition and revenues and expenses for the period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, investment security other-than-temporary impairment judgments and investment security valuation. Cash and Cash Equivalents The Company defines cash and cash equivalents for consolidated cash flow purposes as cash due from banks, federal funds sold and money market funds. Cash flows from loans and deposits are reported net. The balances of cash and due from banks, federal funds sold and money market funds, at times, may exceed federally insured limits. The Company has not experienced any losses from such concentrations. Investment Securities Marketable equity and debt securities are classified as either trading, available-for-sale, or held-to-maturity (applies only to debt securities). Management determines the appropriate classifications of securities at the time of purchase. At December 31, 2016 and 2015, the Company had no debt or equity securities classified as trading. Held-to-maturity securities are debt securities for which the Company has the ability and intent to hold until maturity. All other securities not included in held-to-maturity are classified as available-for-sale. Held-to-maturity securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts. Premiums and discounts on debt securities are amortized or accreted into interest income over the term of the securities using the level yield method. Available-for-sale securities are recorded at fair value. Unrealized gains and losses, net of the related tax effect, on available-for-sale securities are excluded from earnings and are reported in accumulated other comprehensive income, a separate component of equity, until realized. Further information relating to the fair value of securities can be found within Note 4 of the Notes to Consolidated Financial Statements. In accordance with Financial Accounting Standards Board Accounting Standards Codification ("FASB ASC") 320- “Debt and Equity Securities”, a decline in market value of a debt security below amortized cost that is deemed other-than-temporary is charged to earnings for the credit related other-than-temporary impairment ("OTTI"), resulting in the establishment of a new cost basis for the security, while the non-credit related OTTI is recognized in other comprehensive income if there is no intent or requirement to sell the security. The securities portfolio is reviewed on a quarterly basis for the presence of other-than-temporary impairment. If an equity security is deemed other-than-temporarily impaired, the full impairment is considered to be credit-related and a charge to earnings would be recorded. Gains and losses on sales of securities are recognized at the time of sale on a specific identification basis. Federal Home Loan Bank of Boston Stock The Company, which is a member of the Federal Home Loan Bank system, is required to maintain an investment in capital stock of the Federal Home Loan Bank of Boston (“FHLBB”). Based on redemption provisions of the FHLBB, the stock has no quoted market value and is carried at cost. At its discretion, the FHLBB may declare dividends on the stock. The Bank reviews for impairment based on the ultimate recoverability of the cost basis in the FHLBB stock. As of December 31, 2016 and 2015, no impairment has been recognized. Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of amortized cost or fair value, as determined by aggregate outstanding commitments from investors or current investor yield requirements. Net unrealized losses, if any, are recognized through a valuation allowance by charges to other noninterest income in the accompanying Consolidated Statements of Income. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loans sold on the trade date to net gain on loans sold in the accompanying Consolidated Statements of Income. Loans The Company’s loan portfolio segments include residential real estate, commercial real estate, construction, installment, commercial, collateral, home equity lines of credit, demand, revolving credit and resort. Construction includes classes for commercial and residential construction. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. When loans are prepaid, sold or participated out, the unamortized portion is recognized as income or expense at that time. Interest on loans is accrued and recognized in interest income based on contractual rates applied to principal amounts outstanding. Accrual of interest is discontinued, and previously accrued income is reversed, when loan payments are more than 90 days past due or when, in the judgment of management, collectability of the loan or loan interest becomes uncertain. Loans may be returned to accrual status when all principal and interest amounts contractually due (including arrearages) are reasonably assured of repayment within a reasonable period and there is a sustained period of repayment performance (generally a minimum of six months) by the borrower, in accordance with contractual terms involving payment of cash or cash equivalents. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual status. If a residential real estate, commercial real estate, construction, installment, commercial, collateral, home equity line of credit, demand, revolving credit and resort loan is on non-accrual status cash payments are applied towards the reduction of principal. If loans are considered impaired but accruing, cash payments are applied first to interest income and then as a reduction of principal as specified in the contractual agreement, unless the collection of the remaining principal amount due is considered doubtful. The policy for determining past due or delinquency status for all loan portfolio segments is based on the number of days past due or the contractual terms of the loan. A loan is considered delinquent when the customer does not make their payments due according to their contractual terms. Generally, a loan can be demanded at any time if the loan is delinquent or if the borrower fails to meet any other agreed upon terms and conditions. On a quarterly basis, our loan policy requires that we evaluate for impairment all commercial real estate, construction, commercial and resort loan segments that are classified as non-accrual, loans secured by real property in foreclosure or are otherwise likely to be impaired, non-accruing residential and installment loan segments greater than $100,000 and all troubled debt restructurings. Nonperforming loans consist of non-accruing loans, non-accruing loans identified as trouble debt restructurings and loans past due more than 90 days and still accruing interest. Allowance for Loan Losses The allowance for loan losses is maintained at a level believed adequate by management to absorb potential losses inherent in the loan portfolio as of the statement of condition date. The allowance for loan losses consists of a formula allowance following FASB ASC 450 – “Contingencies” and FASB ASC 310 – “Receivables”. The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a quarterly 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. All reserves are available to cover any losses regardless of how they are allocated. 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, construction, installment, commercial, collateral, home equity line of credit, demand, revolving credit and resort. Construction loans include classes for commercial investment real estate construction, commercial owner occupied construction, residential development, residential subdivision construction and residential owner occupied construction loans. 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: levels/trends in delinquencies and nonaccrual loans; trends in volume and terms of loans; effects of changes in risk selection and underwriting standards and other changes in lending policies, procedures and practices; experience/ability/depth of lending management and staff; and national and local economic trends and conditions. There were no material changes in the Company’s policies or methodology pertaining to the general component of the allowance for loan losses during the year ended December 31, 2016. The qualitative factors are determined based on the various risk characteristics of each loan segment. Risk characteristics relevant to each portfolio segment are as follows: Residential real estate – Residential real estate loans are generally originated in amounts up to 95.0% of the lesser of the appraised value or purchase price of the property, with private mortgage insurance required on loans with a loan-to-value ratio in excess of 80.0%. The Company does not grant subprime loans. All loans in this segment are collateralized by owner-occupied residential real estate and repayment is dependent on the credit quality of the individual borrower. All residential mortgage loans are underwritten pursuant to secondary market underwriting guidelines which include minimum FICO standards. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Commercial real estate – Loans in this segment are primarily originated to finance income-producing properties throughout the northeastern states. The underlying cash flows generated by the properties may be adversely impacted by a downturn in the economy as evidenced by increased vacancy rates, which in turn, may have an effect on the credit quality in this segment. Management generally obtains rent rolls and other financial information, as appropriate on an annual basis and continually monitors the cash flows of these loans. Construction loans – Loans in this segment include commercial construction loans, real estate subdivision development loans to developers, licensed contractors and builders for the construction and development of commercial real estate projects and residential properties. Construction lending contains a unique risk characteristic as loans are originated under market and economic conditions that may change between the time of origination and the completion and subsequent purchaser financing of the property. In addition, construction subdivision loans and commercial and residential construction loans to contractors and developers entail additional risks as compared to single-family residential mortgage lending to owner-occupants. These loans typically involve large loan balances concentrated in single borrowers or groups of related borrowers. Real estate subdivision development loans to developers, licensed contractors and builders are generally speculative real estate development loans for which payment is derived from sale of the property. Credit risk may be affected by cost overruns, time to sell at an adequate price, and market conditions. Construction financing is generally considered to involve a higher degree of credit risk than longer-term financing on improved, owner-occupied real estate. Residential construction credit quality may be impacted by the overall health of the economy, including unemployment rates and housing prices. Commercial – Loans in this segment are made to businesses and are generally secured by assets of the business. Repayment is expected from the cash flows of the business. A weakened economy, and resultant decreased consumer spending, will have an effect on the credit quality in this segment. Home equity line of credit – Loans in this segment include home equity loans and lines of credit underwritten with a loan-to-value ratio generally limited to no more than 80%, including any first mortgage. Our home equity lines of credit have a 9 year 10 month draw period followed by a 20 year amortization period and adjustable rates of interest which are indexed to the prime rate. The overall health of the economy, including unemployment rates and housing prices, may have an effect on the credit quality in this segment. Installment, Collateral, Demand, Revolving Credit and Resort – Loans in these segments include loans principally to customers residing in our primary market area with acceptable credit ratings. Our installment and collateral consumer loans generally consist of loans on new and used automobiles, loans collateralized by deposit accounts and unsecured personal loans. The overall health of the economy, including unemployment rates and housing prices, may have an effect on the credit quality in this segment. Excluding collateral loans which are fully collateralized by a deposit account, repayment for loans in these segments is dependent on the credit quality of the individual borrower. The resort portfolio consists of a direct receivable loan outside the Northeast which is amortizing to its contractual obligations. The Company has exited the resort financing market with a residual portfolio remaining. Allocated component: The allocated component relates to loans that are classified as impaired. Impairment is measured on a loan by loan basis for commercial real estate, construction, commercial and resort loans by the present value of expected cash flows discounted at the effective interest rate; the fair value of the collateral, if applicable; or the observable market price for the loan. 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. The Company does not separately identify individual consumer and residential real estate loans for impairment disclosures, unless such loans are subject to a troubled debt restructuring agreement or they are nonaccrual loans with outstanding balances greater than $100,000. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and construction loans by the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. Management updates the analysis quarterly. The assumptions used in appraisals are reviewed for appropriateness. Updated appraisals or valuations are obtained as needed or adjusted to reflect the estimated decline in the fair value based upon current market conditions for comparable properties. The Company periodically may agree to modify the contractual terms of loans. When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a troubled debt restructuring ("TDR"). All TDRs are classified as impaired. Unallocated component: An unallocated component is maintained, when needed, 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. The Company’s Loan Policy allows management to utilize a high and low range of 0.0% to 5.0% of our total allowance for loan losses when establishing an unallocated allowance, when considered necessary. The unallocated allowance is used to provide for an unidentified loss that may exist in emerging problem loans that cannot be fully quantified or may be affected by conditions not fully understood as of the balance sheet date. There was no unallocated allowance at December 31, 2016 and 2015. Troubled Debt Restructuring A loan is considered a troubled debt restructuring (“TDR”) when the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower in modifying or renewing the loan the Company would not otherwise consider. In connection with troubled debt restructurings, terms may be modified to fit the ability of the borrower to repay in line with their current financial status, which may include a reduction in the interest rate to market rate or below, a change in the term or movement of past due amounts to the back-end of the loan or refinancing. A loan is placed on non-accrual status upon being restructured, even if it was not previously, unless the modified loan was current for the six months prior to its modification and we believe the loan is fully collectable in accordance with its new terms. The Company’s policy to restore a restructured loan to performing status is dependent on the receipt of regular payments, generally for a period of six months and one calendar year-end. All troubled debt restructurings are classified as impaired loans and are reviewed for impairment by management on a quarterly basis per Company policy. Mortgage Servicing Rights The Company capitalizes mortgage servicing rights for loans originated and then sold with servicing retained based on the fair market value on the origination date. Mortgage servicing rights are amortized in proportion to and over the period of estimated net servicing income and such amortization is included in the consolidated statements of income as a reduction of mortgage servicing fee income. Mortgage servicing rights are evaluated for impairment by comparing their aggregate carrying amount to their fair value. An independent appraisal of the fair value of the Company’s mortgage servicing rights is obtained quarterly and is used by management to evaluate the reasonableness of the fair value estimates. Management reviews the independent appraisal and performs procedures to determine appropriateness. Impairment is recognized as an adjustment to mortgage servicing rights and mortgage servicing income. Foreclosed Real Estate Real estate acquired through foreclosure comprises properties acquired in partial or total satisfaction of problem loans. The properties are acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. At the time these properties are foreclosed, the properties are initially recorded at the fair value at the date of foreclosure less estimated selling costs. Losses arising at the time of acquisition of such properties are charged against the allowance for loan losses. Subsequent loss provisions are charged to the foreclosed real estate valuation allowance and expenses incurred to maintain the properties are charged to noninterest expense. Properties are evaluated regularly to ensure the recorded amounts are supported by current fair values, and a charge to operations is recorded as necessary to reduce the carrying amount to fair value less estimated costs to dispose. Revenue and expense from the operation of other real estate owned and the provision to establish and adjust valuation allowances are included in noninterest expenses. Costs relating to the development and improvement of the property are capitalized, subject to the limit of fair value of the collateral. In the Consolidated Statements of Financial Condition, total prepaid expenses and other assets include foreclosed real estate of $-0- and $279,000 as of December 31, 2016 and 2015, with no specific valuation allowance. The recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process according to local requirements of the applicable jurisdiction totaled $4.3 million at December 31, 2016. Bank Owned Life Insurance Bank owned life insurance ("'BOLI") represents life insurance on certain employees who have consented to allow the Company to be the beneficiary of those policies. BOLI is recorded as an asset at cash surrender value. Increases in the cash value of the policies, as well as insurance proceeds received, are recorded in other non-interest income and are not subject to income tax. Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets, which range from three to ten years for furniture and equipment and five to forty years for premises. Leasehold improvements are amortized on a straight-line basis over the term of the respective leases, including renewal options, or the estimated useful lives of the improvements, whichever is shorter. Maintenance and repairs are charged to non-interest expense as incurred, while significant improvements are capitalized. Derivative Financial Instruments Interest rate swap derivatives not designated as hedges are offered to certain qualifying commercial customers and to manage the Company’s exposure to interest rate movements and do not meet the hedge accounting parameters under FASB ASC 815 “Derivatives and Hedging”. Derivative financial instruments are recognized as assets and liabilities on the consolidated balance sheet and measured at fair value. Changes in the fair value of derivatives not designated in hedging relationships are recognized directly in earnings. Pension and Other Postretirement Benefit Plans The Company’s non-contributory defined-benefit pension plan and certain defined benefit postretirement plans were frozen as of February 28, 2013 and no additional benefits will accrue. The Company has a non-contributory defined benefit pension plan that provides benefits for substantially all employees hired before January 1, 2007 who meet certain requirements as to age and length of service. The benefits are based on years of service and average compensation, as defined in the Plan Document. The Company’s funding practice is to meet the minimum funding standards established by the Employee Retirement Income Security Act of 1974. In addition to providing pension benefits, we provide certain health care and life insurance benefits for retired employees. Participants or eligible employees hired before January 1, 1993 become eligible for the benefits if they retire after reaching age 62 with fifteen or more years of service. A fixed percent of annual costs are paid depending on length of service at retirement. The Company accrues for the estimated costs of these other post-retirement benefits through charges to expense during the years that employees render service. The Company makes contributions to cover the current benefits paid under this plan. The Company believes the policy for determining pension and other post-retirement benefit expenses is critical because judgments are required with respect to the appropriate discount rate, rate of return on assets and other items. The Company reviews and updates the assumptions annually. If the Company’s estimate of pension and post-retirement expense is too low it may experience higher expenses in the future, reducing its net income. If the Company’s estimate is too high, it may experience lower expenses in the future, increasing its net income. Repurchase Liabilities Repurchase agreements are accounted for as secured borrowings since the Company maintains effective control over the transferred securities and the transfer meets the other criteria for such accounting. Securities are sold to a counterparty with an agreement to repurchase the same or substantially the same security at a specified price and date. The Company has repurchase agreements with commercial or municipal customers that are offered as a commercial banking service. Customer repurchase agreements are for a term of one day and are backed by the purchasers’ interest in certain U.S. Treasury Bills or other U.S. Government securities. Obligations to repurchase securities sold are reflected as a liability in the Consolidated Statements of Financial Condition. The Company does not record transactions of repurchase agreements as sales. The securities underlying the repurchase agreements remain in the available-for-sale investment and held-for-maturity securities portfolios. Transfers of Financial Assets Transfers of an entire financial asset, a group of entire financial assets, or a participating interest in an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets. During the normal course of business, the Company may transfer a portion of a financial asset, for example, a participation loan or the government guaranteed portion of a loan. In order to be eligible for sales treatment, the transfer of the portion of the loan must meet the criteria of a participating interest. If it does not meet the criteria of a participating interest, the transfer must be accounted for as a secured borrowing. In order to meet the criteria for a participating interest, all cash flows from the loan must be divided proportionately, the rights of each loan holder must have the same priority, the loan holders must have no recourse to the transferor other than standard representations and warranties and no loan holder has the right to pledge or exchange the entire loan. Fee Income Fee income for customer services which are not deferred are recorded on an accrual basis when earned. Advertising Costs Advertising costs are expensed as incurred. Income Taxes Deferred income taxes are provided for differences arising in the timing of income and expenses for financial reporting and for income tax purposes. Deferred income taxes and tax benefits are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company provides a deferred tax asset valuation allowance for the estimated future tax effects attributable to temporary differences and carryforwards when realization is determined not to be more likely than not. FASB ASC 740-10 prescribes a recognition threshold that a tax position is required to meet before being recognized in the financial statements and provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition issues. Pursuant to FASB ASC 740-10, the Company examines its financial statements, its income tax provision and its federal and state income tax returns and analyzes its tax positions, including permanent and temporary differences, as well as the major components of income and expense to determine whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. The Company recognizes interest and penalties arising from income tax settlements as part of its provision for income taxes. Employee Stock Ownership Plan (“ESOP”) The Company accounts for its ESOP in accordance with FASB ASC 718-40, “Compensation – Stock Compensation”. Under this guidance, unearned ESOP shares are not considered outstanding and are shown as a reduction of stockholders' equity as unearned compensation. The Company will recognize compensation cost equal to the fair value of the ESOP shares during the periods in which they are committed to be released. To the extent that the fair value of the Company's ESOP shares differs from the cost of such shares, this d

Restrictions On Cash and Due From Banks [Abstract]
Restrictions on Cash and Due from Banks	2. Restrictions on Cash and Due from Banks The Company is required to maintain a percentage of transaction account balances on deposit in non-interest-earning reserves with the Federal Reserve Bank, offset by the Company’s average vault cash. The Company also is required to maintain cash balances to collateralize the Company’s position with certain third parties. The Company had cash and liquid assets of approximately $9.5 million and $17.7 million to meet these requirements at December 31, 2016 and 2015, respectively.

The Company has no intent to sell nor is it more likely than not that the Company will be required to sell any of the securities in a loss position during the period of time necessary to recover the unrealized losses, which may be until maturity. The following summarizes the conclusions from our OTTI evaluation for those security types that incurred significant gross unrealized losses greater than twelve months as of December 31, 2016: Preferred equity securities - The unrealized loss on preferred equity securities in a loss position for 12 months or more relates to one preferred equity security. This investment is in a global financial institution. When estimating the recovery period for securities in an unrealized loss position, management utilizes analyst forecasts, earnings assumptions and other company-specific financial performance metrics. In addition, this assessment incorporates general market data, industry and sector cycles and related trends to determine a reasonable recovery period. Management evaluated the near-term prospects of the issuer in relation to the severity and duration of the impairment. Management concluded that the preferred equity security is not other-than-temporarily impaired at December 31, 2016. Mutual funds - The unrealized loss on mutual funds in a loss position for 12 months or more relates to one mutual fund. The fund invests primarily in high quality debt securities and other debt instruments supporting the affordable housing industry in areas of the United States designated by fund shareholders. When estimating the recovery period for securities in an unrealized loss position, management utilizes analyst forecasts, earnings assumptions and other fund-specific financial performance metrics. In addition, this assessment incorporates general market data, industry and sector cycles and related trends to determine a reasonable recovery period. Management evaluated the near-term prospects of the fund in relation to the severity and duration of the impairment. Management concluded that the mutual fund is not other-than-temporarily impaired at December 31, 2016. The Company recorded no other-than-temporary impairment charges to the investment securities portfolios for the years ended December 31, 2016, 2015 and 2014. There were gross realized gains on sales of securities available-for-sale totaling $-0-, $1.5 million and $-0- for the years ended December 31, 2016, 2015 and 2014, respectively As of December 31, 2016 and 2015, U.S. Treasury, U.S. Government agency obligations and Government sponsored residential mortgage-backed securities with a fair value of $102.4 million and $112.4 million, respectively, were pledged as collateral for loan derivatives, public funds, repurchase liabilities and repurchase agreement borrowings. The amortized cost and estimated fair value of debt securities at December 31, 2016 and 2015 by contractual maturity are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or repay obligations with or without call or repayment penalties: December 31, 2016 Available-for-Sale Held-to-Maturity Estimated Estimated Amortized Fair Amortized Fair Cost Value Cost Value (Dollars in thousands) Due in one year or less $ 33,475 $ 33,490 $ - $ - Due after one year through five years 60,847 60,704 16,000 15,917 Due after five years through ten years - - - - Due after ten years - - - - Government sponsored residential mortgage-backed securities 3,424 3,569 17,061 17,124 $ 97,746 $ 97,763 $ 33,061 $ 33,041 December 31, 2015 Available-for-Sale Held-to-Maturity Estimated Estimated Amortized Fair Amortized Fair Cost Value Cost Value (Dollars in thousands) Due in one year or less $ 54,499 $ 54,511 $ - $ - Due after one year through five years 67,285 67,201 24,000 24,008 Due after five years through ten years - - - - Due after ten years - - - - Government sponsored residential mortgage-backed securities 4,958 5,153 8,246 8,349 $ 126,742 $ 126,865 $ 32,246 $ 32,357 Federal Home Loan Bank of Boston (“FHLBB”) Stock The Company, as a member of the FHLBB, owned $16.4 million and $21.7 million of FHLBB capital stock at December 31, 2016 and 2015, respectively, which is equal to its FHLBB capital stock requirement. The Company evaluated its FHLBB capital stock for potential other-than-temporary impairment at December 31, 2016. Capital adequacy, credit ratings, the value of the stock, overall financial condition of the FHLB system and FHLBB as well as current economic factors were analyzed in the impairment analysis. The Company concluded that its position in FHLBB capital stock is not other-than-temporarily impaired at December 31, 2016. Alternative Investments Alternative investments, which totaled $2.2 million and $2.5 million at December 31, 2016 and 2015, respectively, are included in other assets in the accompanying Consolidated Statements of Financial Condition. The Company’s alternative investments include investments in certain non-public funds, which include limited partnerships, an equity fund and membership stocks. These investments are held at cost and were evaluated for potential other-than-temporary impairment at December 31, 2016.

Credit Quality Information At the time of loan origination, a risk rating based on a nine point grading system is assigned to each commercial-related loan based on the loan officer’s and management’s assessment of the risk associated with each particular loan. This risk assessment is based on an in depth analysis of a variety of factors. More complex loans and larger commitments require the Company’s internal credit risk management department further evaluate the risk rating of the individual loan or relationship, with credit risk management having final determination of the appropriate risk rating. These more complex loans and relationships receive ongoing periodic review to assess the appropriate risk rating on a post-closing basis with changes made to the risk rating as the borrower’s and economic conditions warrant. The Company’s risk rating system is designed to be a dynamic system and we grade loans on a “real time” basis. The Company places considerable emphasis on risk rating accuracy, risk rating justification, and risk rating triggers. The Company’s risk rating process has been enhanced with its implementation of industry-based risk rating “cards.” The cards are used by the loan officers and promote risk rating accuracy and consistency on an institution-wide basis. Most loans are reviewed annually as part of a comprehensive portfolio review conducted by management and/or by an independent loan review firm. More frequent reviews of loans rated low pass, special mention, substandard and doubtful are conducted by the credit risk management department. The Company utilizes an independent loan review consulting firm to review its rating accuracy and the overall credit quality of its loan portfolio. The review is designed to provide an evaluation of the portfolio with respect to risk rating profile as well as with regard to the soundness of individual loan files. The individual loan reviews include an analysis of the creditworthiness of obligors, via appropriate key ratios and cash flow analysis and an assessment of collateral protection. The consulting firm conducts two loan reviews per year aiming at a 65.0% or higher commercial and industrial loans and commercial real estate portfolio penetration. Summary findings of all loan reviews performed by the outside consulting firm are reported to the board of directors and senior management of the Company upon completion. The Company utilizes a point risk rating scale as follows: Risk Rating Definitions Residential and consumer loans are not rated unless they are 45 days or more delinquent, in which case, depending on past-due days, they will be rated 6, 7 or 8. Loans rated 1 – 5, 55: Commercial loans in these categories are considered “pass” rated loans with low to average risk. Loans rated 6: Residential, Consumer and Commercial loans in this category are considered “special mention.” These loans are starting to show signs of potential weakness and are being closely monitored by management. Loans rated 7: Loans in this category are considered “substandard.” Generally, a loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. There is a distinct possibility that the Company will sustain some loss if the weakness is not corrected. Loans rated 8: Loans in this category are considered “doubtful.” Loans classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable. Loans rated 9: Loans in this category are considered uncollectible (“loss”) and of such little value that their continuance as loans is not warranted.

Delinquency notices are mailed monthly to all delinquent borrowers, advising them of the amount of their delinquency. Residential and consumer lending borrowers are typically given 30 days to pay the delinquent payments or to contact us to make arrangements to bring the loan current over a longer period of time. Generally, if a residential or consumer lending borrower fails to bring the loan current within 90 days from the original due date or to make arrangements to cure the delinquency over a longer period of time, the matter is referred to legal counsel and foreclosure or other collection proceedings are initiated. The Company may consider forbearance or a loan restructuring in certain circumstances where a temporary loss of income is the primary cause of the delinquency, and if a reasonable plan is presented by the borrower to cure the delinquency in a reasonable period of time after his or her income resumes. Problem or delinquent borrowers in our commercial real estate, commercial business and resort portfolios are handled on a case-by-case basis, typically by our Special Assets Department. Appropriate problem-resolution and workout strategies are formulated based on the specific facts and circumstances.

Pension and Other Postretirement Benefit Plans	10. Pension and Other Postretirement Benefit Plans The Company maintains a non-contributory defined-benefit pension plan covering eligible employees hired prior to January 1, 2007. The Company also maintains a supplemental retirement plan (“supplemental plan”) to provide benefits to certain employees whose calculated benefit under the qualified plan exceeds the Internal Revenue Service limitation. The Company sponsors two defined benefit postretirement plans that cover eligible employees. One plan provides health (medical and dental) benefits, and the other provides life insurance benefits. The accounting for the health care plan anticipates no future cost-sharing changes. The Company does not advance fund its postretirement plans. On December 27, 2012, the Company announced it would freeze the non-contributory defined-benefit pension plan and certain defined benefit postretirement plans as of February 28, 2013. All benefits under these plans were frozen as of that date and no additional benefits will accrue. The measurement date for each plan is the Company’s year end. The amounts related to the qualified plan and the supplemental plan is reflected in the tables that follow as “Pension Plans.” Both of these plans have projected and accumulated benefit obligations in excess of plan assets. The following table sets forth the change in benefit obligation, plan assets and the funded status of the pension plans and other postretirement benefits: Pension Plans Other Postretirement Benefits Year Ended December 31, Year Ended December 31, 2016 2015 2016 2015 (Dollars in thousands) Change in benefit obligation: Benefit obligation at beginning of year $ 25,175 $ 26,923 $ 2,899 $ 3,224 Service cost - - 56 75 Interest cost 1,051 1,036 119 127 Actuarial loss (gain) 512 (1,689 ) (414 ) (442 ) Benefits paid (1,105 ) (1,095 ) (92 ) (85 ) Benefit obligation at end of year 25,633 25,175 2,568 2,899 Change in plan assets: Fair value of plan assets at beginning of year 19,023 19,271 - - Actual return on plan assets 1,292 (379 ) - - Employer contributions 226 1,226 92 85 Benefits paid (1,105 ) (1,095 ) (92 ) (85 ) Fair value of plan assets at end of year 19,436 19,023 - - Funded status recognized in the statements of condition $ (6,197 ) $ (6,152 ) $ (2,568 ) $ (2,899 ) Accumulated benefit obligation $ (25,633 ) $ (25,175 ) The following table presents the amounts recognized in accumulated other comprehensive income that have not yet been recognized as a component of net period benefit cost as of December 31, 2016 and 2015: Pension Plans Other Postretirement Benefits Year Ended December 31, Year Ended December 31, 2016 2015 2016 2015 (Dollars in thousands) Prior service cost $ - $ - $ 121 $ 155 Actuarial (loss) gain (6,792 ) (7,044 ) 244 (24 ) Unrecognized components of net periodic benefit cost in accumulated other comprehensive loss, net of tax $ (6,792 ) $ (7,044 ) $ 365 $ 131 The following tables set forth the components of net periodic pension and benefit costs for the pension plans and other postretirement plans and other amounts recognized in accumulated other comprehensive loss for the retirement plans and post retirement plans for the years ended December 31, 2016, 2015 and 2014: Pension Plans Year Ended December 31, 2016 2015 2014 (Dollars in thousands) Components of net periodic pension cost: Service cost $ - $ - $ - Interest cost 1,051 1,036 1,022 Expected return on plan assets (1,113 ) (1,448 ) (1,339 ) Amortization of unrecognized prior service cost - - - Recognized net actuarial loss 704 709 306 Curtailment charge - - - Net periodic pension cost 642 297 (11 ) Change in plan assets and benefit obligations recognized in other comprehensive income: Net loss (1) 335 138 5,683 Amortization of net loss (704 ) (709 ) (306 ) Amortization of prior service cost - - - Curtailment charge - - - Total recognized in other comprehensive income (369 ) (571 ) 5,377 Total recognized in net periodic pension cost and other comprehensive income $ 273 $ (274 ) $ 5,366 (1) For the year ended December 31, 2014, the increase in loss was primarily due to the mortality tables being updated from IRS 2013 Combined Static Mortality to SOA RP-2014 Total Dataset Mortality with Scale MP-2014, which better reflected the overall mortality trend in private pension plans in the U.S. and a change in the discount rate.

The discount rate model produced a single weighted average discount rate of 4.08% that when used to discount the same plan benefit cash flows, resulted in the same aggregate present value. Plan Assets Fair value estimates are made as of a specific point in time based on the characteristics of the financial instruments and relevant market information. In accordance with FASB ASC 820, the fair value estimates are measured within the fair value hierarchy. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). Basis of Fair Value Measurement 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. The following is a description of the valuation methodologies used for the pension plan assets measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy. Mutual funds: The fair value of the Company’s pension plan assets at December 31, 2016 and 2015 by asset category are listed in the tables below: December 31, 2016 Investments at Fair Value (Dollars in thousands) Level 1 Level 2 Level 3 Total Mutual funds: Fixed income $ 5,719 $ - $ - $ 5,719 Equity 5,667 - - 5,667 Pooled separate accounts measured at net asset value (1) Equity separate account (2) 6,944 Money market separate account (3) 385 High yield separate account (4) 721 $ 11,386 $ - $ - $ 19,436 December 31, 2015 Investments at Fair Value (Dollars in thousands) Level 1 Level 2 Level 3 Total Mutual funds: Fixed income $ 6,659 $ - $ - $ 6,659 Equity 5,522 - - 5,522 Pooled separate accounts measured at net asset value (1) Equity separate account (2) 6,136 Money market separate account (3) 3 High yield separate account (4) 703 $ 12,181 $ - $ - $ 19,023 (1) - In accordance with Subtopic 820-10, certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts in this table are intended to permit reconciliation of the fair value hierarchy to the fair value of plan assets at end of year. (2) - Primarily invests in common stocks of companies with large market capitalization. (3) - Invests in high quality, short-term money market instruments. (4) - Invests in below investment grade bonds, bank loans and securities of foreign issuers. Pooled Separate Accounts (PSA): Investment Strategy and Asset Allocations Plan assets are to be managed within an ERISA framework so as to provide the greatest probability that the following long-term objectives for the qualified pension plan are met in a prudent manner. The Company recognizes that, for any given time period, the attainment of these objectives is in large part dictated by the returns available from the capital markets in which plan assets are invested. The asset allocation of plan assets reflects the Company’s long-term return expectations and risk tolerance in meeting the financial objectives of the plan. Plan assets should be adequately diversified by asset class, sector and industry to reduce the downside risk to total plan results over short-term time periods, while providing opportunities for long-term appreciation. The Company’s Human Resource Committee reserves the right to rebalance the assets at any time it deems it to be prudent. The Company’s qualified defined benefit pension plan’s weighted-average asset allocations and the Plan’s long-term allocation structure by asset category are as follows: Actual Percentage of Fair Value At December 31, Target 2016 2015 Allocation Cash 5 % 6 % 5-15% Equity funds 60 % 58 % 30-70% Fixed income funds 35 % 36 % 30-70% Total 100 % 100 % Expected Contributions The Company makes contributions to its funded qualified defined benefit plan as required by government regulation or as deemed appropriate by management after considering the fair value of plan assets, expected return on such assets and the present value of the benefit obligation of the plan. The Company expects to make a $1.5 million contribution to the qualified defined benefit plan for the year ended December 31, 2017. Since the supplemental plan and the postretirement benefit plans are unfunded, the expected employer contributions for the year ending December 31, 2017 is equal to the Company’s estimated future benefit payment liabilities less any participant contributions. Expected Benefit Payments The following is a summary of benefit payments expected to be paid by the non-contributory defined benefit pension plans (dollars in thousands): 2017 $ 1,218 2018 1,214 2019 1,273 2020 1,313 2021 1,338 Years 2022 - 2026 7,043 $ 13,399 The following is a summary of benefit payments expected to be paid by the medical, dental and life insurance plan (dollars in thousands): 2017 $ 131 2018 129 2019 134 2020 138 2021 138 Years 2022 - 2026 741 $ 1,411 401(k) Plan Employees who have completed six months of service and have attained the age of 21 are eligible to participate in the Company’s defined contribution savings plan (“401(k) plan”). Eligible employees may contribute an unlimited amount (not to exceed IRS limits) of their compensation. The Company may make a qualified non-elective contribution in an amount equal to 3% of the participant’s compensation. Contributions by the Company for the years ended December 31, 2016, 2015 and 2014 were $682,000, $814,000 and $763,000 respectively. There were no discretionary employer contributions made for the years ended December 31, 2016, 2015 and 2014. Supplemental Plans The Company has entered into agreements with certain current and retired executives to provide supplemental retirement benefits. The present values of these future payments, not included in the previous table, are included in accrued expenses and other liabilities in the Statements of Financial Condition. As of December 31 2016 and 2015, the accrued supplemental retirement liability was $4.7 million and $3.9 million, respectively. For the years ended December 31, 2016, 2015 and 2014 net expense for these supplemental retirement benefits were $850,000, $712,000 and $703,000, respectively. Employee Stock Ownership Plan The Company established the ESOP to provide eligible employees the opportunity to own Company stock. The Company provided a loan to the Farmington Bank Employee Stock Ownership Plan Trust in the amount needed to purchase up to 1,430,416 shares of the Company’s common stock. The loan bears an interest rate equal to the Wall Street Journal Prime Rate plus one percentage point, adjusted annually, and provides for annual payments of interest and principal over the 15 year term of the loan. At December 31, 2016, the loan had an outstanding balance of $11.1 million and an interest rate of 4.75%. The Bank has committed to make contributions to the ESOP sufficient to support the debt service of the loan. The loan is secured by the unallocated shares purchased. The ESOP compensation expense was $1.7 million, $1.5 million and $1.5 million for the years ended December 31, 2016, 2015 and 2014, respectively. Shares held by the ESOP include the following as of December 31, 2016: Allocated 476,805 Committed to be released 95,361 Unallocated 858,250 1,430,416 The fair value of unallocated ESOP shares was $19.4 million at December 31, 2016.

Stock Incentive Plan	11. Stock Incentive Plans In May 2016, the Company’s shareholders approved the First Connecticut Bancorp, Inc. 2016 Stock Incentive Plan (the “2016 Plan”). The 2016 Plan provides for a total of 300,000 shares of common stock for issuance upon the grant or exercise of awards. The Company has not issued any shares from the 2016 Plan as of December 31, 2016. In August 2012, the Company implemented the First Connecticut Bancorp, Inc. 2012 Stock Incentive Plan (the “2012 Plan”). The 2012 Plan provides for a total of 2,503,228 shares of common stock for issuance upon the grant or exercise of awards. The Plan allows for the granting of 1,788,020 non-qualified stock options and 715,208 shares of restricted stock. In accordance with generally accepted accounting principles for Share-Based Payments, the Company expenses the fair value of all share-based compensation grants over the requisite service periods. Under the 2012 Plan, stock options granted vested 20% immediately and will vest 20% at each annual anniversary of the grant date and expire ten years after grant date. The Company recognizes compensation expense for the fair values of these awards, which vest on a straight-line basis over the requisite service period of the awards. Restricted shares granted vested 20% immediately and vested 20% at each annual anniversary of the grant date through 2016. The product of the number of shares granted and the grant date market price of the Company’s common stock determines the fair value of restricted shares under the Company’s restricted stock plan. The Company recognizes compensation expense for the fair value of restricted shares on a straight-line basis over the requisite service period for the entire award. The Company classifies share-based compensation for employees within “Salaries and employee benefits” and share-based payments for outside directors within “Other operating expenses” in the Consolidated Statements of Income. For the years ended December 31, 2016, 2015 and 2014, the Company recorded $1.8 million, $3.1 million and $2.9 million of share-based compensation expense, respectively, comprised of $746,000, $1.3 million and $1.2 million of stock option expense, respectively and $1.0 million, $1.8 million and $1.7 million of restricted stock expense, respectively. Expected future compensation expense relating to the 49,150 non-vested options outstanding at December 31, 2016, is $131,000 over the remaining weighted-average period of 2.14 years. The fair value of the options awarded is estimated on the date of grant using the Black-Scholes option pricing model that uses the assumptions noted in the following table. Expected volatility is based on the Company’s historical volatility and the historical volatility of a peer group as the Company does not have reliably determined stock price for the period needed that is at least equal to its expected term and the Company’s recent historical volatility may not reflect future expectations. The peer group consisted of financial institutions located in New England and the Mid-Atlantic regions of the United States based on whose common stock is traded on a national securities exchange, asset size, tangible capital ratio and earnings factors. The expected term of options granted is derived from using the simplified method due to the Company not having sufficient historical share option experience upon which to estimate an expected term. The risk-free rate is based on the grant date for a traded zero-coupon U.S. Treasury bond with a term equal to the option’s expected term. Weighted-average assumptions for the year ended December 31, 2016 and 2015: 2016 2015 Weighted per share average fair value of options granted $ 3.00 $ 3.33 Weighted-average assumptions: Risk-free interest rate 1.53 % 1.61 % Expected volatility 22.88 % 24.97 % Expected dividend yield 2.13 % 1.99 % Weighted-average dividend yield 1.91 - 2.25 % 1.50% - 2.35 % Expected life of options granted 6.0 years 6.0 years The following is a summary of the Company’s stock option activity and related information for its option grants for the year ended December 31, 2016.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	12. Derivative Financial Instruments Non-Hedge Accounting Derivatives/Non-designated Hedges: The Company does not use derivatives for trading or speculative purposes. Interest rate swap derivatives not designated as hedges are offered to certain qualifying commercial customers and to manage the Company’s exposure to interest rate movements but do not meet the strict hedge accounting definition under FASB ASC 815, “Derivatives and Hedging”. The interest rate swap agreements enable these customers to synthetically fix the interest rate on variable interest rate loans. The customers pay a variable rate and enter into a fixed rate swap agreement with the Company. The credit risk associated with the interest rate swap derivatives executed with these customers is essentially the same as that involved in extending loans and is subject to the Company’s normal credit policies. The Company obtains collateral, if needed, based upon its assessment of the customers’ credit quality. Generally, interest rate swap agreements are offered to “pass” rated customers requesting long-term commercial loans or commercial mortgages in amounts generally of at least $1.0 million. The interest rate swap agreement with our customers is cross-collateralized by the loan collateral. The interest rate swap agreements do not have any embedded interest rate caps or floors. For every variable interest rate swap agreement entered into with a commercial customer, the Company simultaneously enters into a fixed rate interest rate swap agreement with a correspondent bank, agreeing to pay a fixed income stream and receive a variable interest rate swap. The Company is party to master netting agreements with its correspondent banks; however, the Company does not offset assets and liabilities for financial statement presentation purposes. The master netting agreements provide for a single net settlement of all swap agreements, as well as collateral, in the event of default on, or termination of, any one contract. Collateral generally in the form of cash is received or posted by the counterparty with the net liability position, in accordance with contract thresholds. As of December 31, 2016, the Company maintained a cash balance of $2.0 million with a correspondent bank to collateralize its position. The Company has an agreement with a correspondent bank to secure any outstanding receivable in excess of $10.0 million. Credit-risk-related Contingent Features The Company’s agreements with its derivative counterparties contain the following provisions: · if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations; · if the Company fails to maintain its status as a well/adequately capitalized institution, then the counterparty could terminate the derivative positions, and the Company would be required to settle its obligations under the agreements; · if the Company fails to maintain a specified minimum leverage ratio, then the Company could be declared in default on its derivative obligations; and · if a specified event or condition occurs that materially changes the Company’s creditworthiness in an adverse manner, it may be required to fully collateralize its obligations under the derivative instrument. The Company is in compliance with the above provisions as of December 31, 2016. The Company has established a derivatives policy which sets forth the parameters for such transactions (including underwriting guidelines, rate setting process, maximum maturity, approval and documentation requirements), as well as identifies internal controls for the management of risks related to these hedging activities (such as approval of counterparties, limits on counterparty credit risk, maximum loan amounts, and limits to single dealer counterparties). The interest rate swap derivatives executed with our customers and our counterparties, are marked to market and are included with prepaid expenses and other assets and accrued expenses and other liabilities on the Consolidated Statements of Financial Condition at fair value. The Company had the following outstanding interest rate swaps that were not designated for hedge accounting: December 31, 2016 December 31, 2015 (Dollars in thousands) Consolidated # of Notional Estimated # of Notional Estimated Commercial loan customer interest rate swap position Other Assets 51 $ 242,351 $ 7,095 60 $ 257,693 $ 10,564 Commercial loan customer interest rate swap position Other Liabilities 33 148,097 (4,502 ) 6 23,411 (78 ) Counterparty interest rate swap position Other Liabilities 84 390,448 (2,687 ) 66 281,104 (10,599 ) The Company recorded the changes in the fair value of non-hedge accounting derivatives as a component of other noninterest income except for interest received and paid which is reported in interest income in the accompanying Consolidated Statements of Income as follows: Years Ended December 31, 2016 2015 2014 Interest Income MTM Gain Net Impact Interest Income MTM Gain Net Impact Interest Income MTM Gain Net Impact (Dollars in thousands) Commercial loan customer interest rate swap position $ (5,750 ) $ (3,469 ) $ (9,219 ) $ (5,301 ) $ 3,397 $ (1,904 ) $ (3,704 ) $ 3,929 $ 225 Counterparty interest rate swap position 5,750 3,469 9,219 5,301 (3,397 ) 1,904 3,704 (3,929 ) (225 ) Total $ - $ - $ - $ - $ - $ - $ - $ - $ - Mortgage Banking Derivatives Certain derivative instruments, primarily forward sales of mortgage loans and mortgage-backed securities (“MBS”) are utilized by the Company in its efforts to manage risk of loss associated with its mortgage loan commitments and mortgage loans held for sale. Prior to closing and funding certain single-family residential mortgage loans, an interest-rate lock commitment is generally extended to the borrower. During the period from commitment date to closing date, the Company is subject to the risk that market rates of interest may change. If market rates rise, investors generally will pay less to purchase such loans resulting in a reduction in the gain on sale of the loans or, possibly, a loss. In an effort to mitigate such risk, forward delivery sales commitments, under which the Company agrees to deliver whole mortgage loans to various investors or issue MBS, are established. At December 31, 2016, the notional amount of outstanding rate locks totaled approximately $15.5 million. The notional amount of outstanding commitments to sell residential mortgage loans totaled approximately $16.9 million, which included mandatory forward commitments totaling approximately $11.4 million at December 31, 2016. The forward commitments establish the price to be received upon the sale of the related mortgage loan, thereby mitigating certain interest rate risk. There is, however, still certain execution risk specifically related to the Company’s ability to close and deliver to its investors the mortgage loans it has committed to sell.

The collateral is held by a third party financial institution in the Company's trustee account. The counterparty has the right to sell or repledge the investment securities if the Company defaults. The Company is required by the counterparty to maintain adequate collateral levels. In the event the collateral fair value falls below stipulated levels, the Company will pledge additional securities. The Company closely monitors collateral levels to ensure adequate levels are maintained, while mitigating the potential risk of over-collateralization in the event of counterparty default.

Financial Instruments With Off Balance Sheet Risk Disclosure [Abstract]
Financial Instruments with off-balance sheet risk	14. Financial Instruments with Off-Balance Sheet Risk The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and unused lines of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated Statements of Financial Condition. The contract amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Financial instruments whose contract amounts represent credit risk are as follows: December 31, December 31, 2016 2015 (Dollars in thousands) Approved loan commitments $ 102,436 $ 46,144 Unadvanced portion of construction loans 57,124 44,457 Unused lines for home equity loans 199,191 204,983 Unused revolving lines of credit 355 365 Unused commercial letters of credit 3,820 3,558 Unused commercial lines of credit 246,622 187,819 $ 609,548 $ 487,326 Financial instruments with off-balance sheet risk had a valuation allowance of $153,000 and $501,000 as of December 31, 2016 and 2015, respectively. 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 many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Company upon extension of credit is based on management’s credit evaluation of the counterparty. Collateral held is primarily residential property and commercial assets. At December 31, 2016 and 2015, the Company had no off-balance sheet special purpose entities and participated in no securitizations of assets.

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2016
Fair Value Disclosures [Abstract]
Fair Value Measurements	16. Fair Value Measurements Fair value estimates are made as of a specific point in time based on the characteristics of the financial instruments and relevant market information. In accordance with FASB ASC 820-10, the fair value estimates are measured within the fair value hierarchy. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under FASB ASC 820-10 are described as follows: · Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; · Level 2 - Quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability; · Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. When available, quoted market prices are used. In other cases, fair values are based on estimates using present value or other valuation techniques. These techniques involve uncertainties and are significantly affected by the assumptions used and judgments made regarding risk characteristics of various financial instruments, discount rates, and estimates of future cash flows, future expected loss experience and other factors. Changes in assumptions could significantly affect these estimates. Derived fair value estimates cannot be substantiated by comparison to independent markets and, in certain cases, could not be realized in an immediate sale of the instrument. Fair value estimates are based on existing financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not financial instruments. Accordingly, the aggregate fair value amounts presented do not purport to represent the underlying market value of the Company. There were no transfers between levels during the years ended December 31, 2016 and 2015. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following is a description of the valuation methodologies used for instruments measured at fair value: Securities Available-for-Sale: The Company utilizes a third party, nationally-recognized pricing service (“pricing service”); subject to review by management, to estimate fair value measurements for the majority of its investment securities portfolio. The pricing service evaluates each asset class based on relevant market information considering observable data that may include dealer quotes, reported trades, market spreads, cash flows, the U.S. Treasury yield curve, the LIBOR swap yield curve, trade execution data, market prepayment speeds, credit information and the bond’s terms and conditions, among other things. The fair value prices on all investment securities are reviewed for reasonableness by management. Also, management assessed the valuation techniques used by the pricing service based on a review of their pricing methodology to ensure proper pricing and hierarchy classifications. Management employs procedures to monitor the pricing service’s assumptions and establishes processes to challenge the pricing service’s valuations that appear unusual or unexpected.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Certain assets and liabilities are measured at fair value on a non-recurring basis in accordance with generally accepted accounting principles. These include assets that are measured at the lower of cost or market that were recognized at fair value below cost at the end of the period as well as assets that are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment.

At December 31, 2016, there was no valuation allowance recorded against the deferred tax assets. At December 31, 2015, the Company recorded a $771,000 valuation allowance against the deferred tax assets. As part of the Plan of Conversion and Reorganization completed on June 29, 2011, the Company contributed shares of Company common stock to the Farmington Bank Community Foundation, Inc. This contribution resulted in a charitable contribution deduction for federal income tax purposes. Use of that charitable contribution deduction is limited under Federal tax law to 10% of federal taxable income without regard to charitable contributions, net operating losses, and dividend received deductions. Annually, a corporation is permitted to carry over to the five succeeding tax years, contributions that exceeded the 10% limitation, but also subject to the maximum annual limitation. In 2015, the Company recorded a $771,000 valuation allowance related to a deferred tax asset associated with the establishment of the Bank’s foundation in 2011. In the fourth quarter of 2016, the valuation allowance established in 2015 of $771,000 was reversed and the related deferred tax asset totaling $137,000 was written-off. During 1999, the Bank formed a subsidiary, Farmington Savings Loan Servicing Inc., which qualifies and operates as a Connecticut passive investment company pursuant to legislation enacted in May 1998. Income earned by a passive investment company is exempt from Connecticut corporation business tax. In addition, dividends paid by Farmington Savings Loan Servicing, Inc. to its parent, Farmington Bank are also exempt from corporation business tax. The Bank expects the passive investment company to earn sufficient income to eliminate Connecticut income taxes in future years. As such, no Connecticut related deferred tax assets or liabilities have been recorded. The Company has not provided deferred taxes for the tax reserve for bad debts, of approximately $3.4 million, that arose in tax years beginning before 1987 because it is expected that the requirements of Internal Revenue Code Section 593 will be met in the foreseeable future. There was no interest expense related to uncertain tax positions recognized in income tax for the years ended December 31, 2016, 2015 and 2014. The Company had no uncertain tax positions as of December 31, 2016. The Company is currently open to audit under the statute of limitations by the Internal Revenue Service and state taxing authorities for the years ended December 31, 2013 through 2016.

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 their financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company’s and the Bank’s capital amounts and classifications are also subject to quantitative judgments by the regulators about components, risk weightings and other factors. In July 2013, the Federal Reserve published final rules for the adoption of the Basel III regulatory capital framework (the "Basel III Capital Rules"). The Basel III Capital Rules, among other things, (i) introduced a new capital measure called "Common Equity Tier 1", (ii) specify that Tier 1 capital consists of Common Equity Tier 1 and "Additional Tier 1 Capital" instruments meeting specified requirements, (iii) define Common Equity Tier 1 narrowly by requiring that most deductions/adjustments to regulatory capital measures be made to Common Equity Tier 1 and not to the other components of capital and (iv) expand the scope of the deductions/adjustments as compared to existing regulations and a higher minimum Tier I capital requirement. Additionally, institutions must maintain a capital conservation buffer of common equity Tier 1 capital in an amount greater than 2.5% of total risk-weighted assets to avoid being subject to limitations on capital distributions and discretionary bonus payments to executive officers. The Basel III Capital Rules became effective for the Company beginning on January 1, 2015 with certain transition provisions fully phased in through January 1, 2019. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total capital, Tier I capital and common equity Tier I capital (as defined in the regulations) to risk-weighted assets (as defined in the regulations) and of Tier I capital (as defined in the regulations) to average assets (as defined in the regulations). Management believes, as of December 31, 2016 and 2015 that the Company and the Bank meet all capital adequacy requirements to which they are subject. The Federal Deposit Insurance Corporation categorizes the Company and the Bank as well capitalized under the regulatory framework for prompt corrective action as of December 31, 2016. To be categorized as well capitalized, the Company and the Bank must maintain minimum total risk-based, Tier I risk-based, common equity Tier I capital and Tier I leverage ratios as set forth in the table. There are no conditions or events since that notification that management believes have changed the institution’s category.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Organization and Business	Organization and Business First Connecticut Bancorp, Inc. is a Maryland-chartered bank holding company that wholly owns its only subsidiary, Farmington Bank (collectively with its subsidiary, the “Company”). Farmington Bank's main office is located in Farmington, Connecticut. Farmington Bank is a full-service, community bank with 24 branch locations throughout central Connecticut and western Massachusetts, offering commercial and residential lending as well as wealth management services. Farmington Bank's primary source of income is interest accrued on loans to customers, which include small and middle market businesses and individuals residing primarily in Connecticut and western Massachusetts. However, the Bank will selectively lend to borrowers in other northeastern states. Wholly-owned subsidiaries of Farmington Bank are Farmington Savings Loan Servicing, Inc., a passive investment company that was established to service and hold loans collateralized by real property; Village Investments, Inc.; the Village Corp., Limited, and Village Square Holdings, Inc.; 28 Main Street Corp., is a subsidiary that was formed to hold residential other real estate owned and Village Management Corp., is a subsidiary that was formed to hold commercial other real estate owned, are presently inactive. On June 21, 2013, the Company received regulatory approval to repurchase up to 1,676,452 shares, or 10% of its current outstanding common stock. During the year ended December 31, 2016, the Company had repurchased 156,800 of these shares at a cost of $2.5 million. Repurchased shares are held as treasury stock and are available for general corporate purposes. The Company has 600,945 shares remaining available to be repurchased at December 31, 2016.
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. The consolidated financial statements include the accounts of First Connecticut Bancorp, Inc. and its wholly-owned subsidiary, Farmington Bank. All significant intercompany transactions and balances have been eliminated in consolidation. In preparing the consolidated financial statements, management is required to make extensive use of estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the statement of condition and revenues and expenses for the period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, investment security other-than-temporary impairment judgments and investment security valuation.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company defines cash and cash equivalents for consolidated cash flow purposes as cash due from banks, federal funds sold and money market funds. Cash flows from loans and deposits are reported net. The balances of cash and due from banks, federal funds sold and money market funds, at times, may exceed federally insured limits. The Company has not experienced any losses from such concentrations.
Investment Securities	Investment Securities Marketable equity and debt securities are classified as either trading, available-for-sale, or held-to-maturity (applies only to debt securities). Management determines the appropriate classifications of securities at the time of purchase. At December 31, 2016 and 2015, the Company had no debt or equity securities classified as trading. Held-to-maturity securities are debt securities for which the Company has the ability and intent to hold until maturity. All other securities not included in held-to-maturity are classified as available-for-sale. Held-to-maturity securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts. Premiums and discounts on debt securities are amortized or accreted into interest income over the term of the securities using the level yield method. Available-for-sale securities are recorded at fair value. Unrealized gains and losses, net of the related tax effect, on available-for-sale securities are excluded from earnings and are reported in accumulated other comprehensive income, a separate component of equity, until realized. Further information relating to the fair value of securities can be found within Note 4 of the Notes to Consolidated Financial Statements. In accordance with Financial Accounting Standards Board Accounting Standards Codification ("FASB ASC") 320- “Debt and Equity Securities”, a decline in market value of a debt security below amortized cost that is deemed other-than-temporary is charged to earnings for the credit related other-than-temporary impairment ("OTTI"), resulting in the establishment of a new cost basis for the security, while the non-credit related OTTI is recognized in other comprehensive income if there is no intent or requirement to sell the security. The securities portfolio is reviewed on a quarterly basis for the presence of other-than-temporary impairment. If an equity security is deemed other-than-temporarily impaired, the full impairment is considered to be credit-related and a charge to earnings would be recorded. Gains and losses on sales of securities are recognized at the time of sale on a specific identification basis.
Federal Home Loan Bank of Boston Stock	Federal Home Loan Bank of Boston Stock The Company, which is a member of the Federal Home Loan Bank system, is required to maintain an investment in capital stock of the Federal Home Loan Bank of Boston (“FHLBB”). Based on redemption provisions of the FHLBB, the stock has no quoted market value and is carried at cost. At its discretion, the FHLBB may declare dividends on the stock. The Bank reviews for impairment based on the ultimate recoverability of the cost basis in the FHLBB stock. As of December 31, 2016 and 2015, no impairment has been recognized.
Loans Held for Sale	Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of amortized cost or fair value, as determined by aggregate outstanding commitments from investors or current investor yield requirements. Net unrealized losses, if any, are recognized through a valuation allowance by charges to other noninterest income in the accompanying Consolidated Statements of Income. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loans sold on the trade date to net gain on loans sold in the accompanying Consolidated Statements of Income.
Loans	Loans The Company’s loan portfolio segments include residential real estate, commercial real estate, construction, installment, commercial, collateral, home equity lines of credit, demand, revolving credit and resort. Construction includes classes for commercial and residential construction. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. When loans are prepaid, sold or participated out, the unamortized portion is recognized as income or expense at that time. Interest on loans is accrued and recognized in interest income based on contractual rates applied to principal amounts outstanding. Accrual of interest is discontinued, and previously accrued income is reversed, when loan payments are more than 90 days past due or when, in the judgment of management, collectability of the loan or loan interest becomes uncertain. Loans may be returned to accrual status when all principal and interest amounts contractually due (including arrearages) are reasonably assured of repayment within a reasonable period and there is a sustained period of repayment performance (generally a minimum of six months) by the borrower, in accordance with contractual terms involving payment of cash or cash equivalents. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual status. If a residential real estate, commercial real estate, construction, installment, commercial, collateral, home equity line of credit, demand, revolving credit and resort loan is on non-accrual status cash payments are applied towards the reduction of principal. If loans are considered impaired but accruing, cash payments are applied first to interest income and then as a reduction of principal as specified in the contractual agreement, unless the collection of the remaining principal amount due is considered doubtful. The policy for determining past due or delinquency status for all loan portfolio segments is based on the number of days past due or the contractual terms of the loan. A loan is considered delinquent when the customer does not make their payments due according to their contractual terms. Generally, a loan can be demanded at any time if the loan is delinquent or if the borrower fails to meet any other agreed upon terms and conditions. On a quarterly basis, our loan policy requires that we evaluate for impairment all commercial real estate, construction, commercial and resort loan segments that are classified as non-accrual, loans secured by real property in foreclosure or are otherwise likely to be impaired, non-accruing residential and installment loan segments greater than $100,000 and all troubled debt restructurings. Nonperforming loans consist of non-accruing loans, non-accruing loans identified as trouble debt restructurings and loans past due more than 90 days and still accruing interest.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is maintained at a level believed adequate by management to absorb potential losses inherent in the loan portfolio as of the statement of condition date. The allowance for loan losses consists of a formula allowance following FASB ASC 450 – “Contingencies” and FASB ASC 310 – “Receivables”. The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a quarterly 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. All reserves are available to cover any losses regardless of how they are allocated. 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, construction, installment, commercial, collateral, home equity line of credit, demand, revolving credit and resort. Construction loans include classes for commercial investment real estate construction, commercial owner occupied construction, residential development, residential subdivision construction and residential owner occupied construction loans. 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: levels/trends in delinquencies and nonaccrual loans; trends in volume and terms of loans; effects of changes in risk selection and underwriting standards and other changes in lending policies, procedures and practices; experience/ability/depth of lending management and staff; and national and local economic trends and conditions. There were no material changes in the Company’s policies or methodology pertaining to the general component of the allowance for loan losses during the year ended December 31, 2016. The qualitative factors are determined based on the various risk characteristics of each loan segment. Risk characteristics relevant to each portfolio segment are as follows: Residential real estate – Residential real estate loans are generally originated in amounts up to 95.0% of the lesser of the appraised value or purchase price of the property, with private mortgage insurance required on loans with a loan-to-value ratio in excess of 80.0%. The Company does not grant subprime loans. All loans in this segment are collateralized by owner-occupied residential real estate and repayment is dependent on the credit quality of the individual borrower. All residential mortgage loans are underwritten pursuant to secondary market underwriting guidelines which include minimum FICO standards. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Commercial real estate – Loans in this segment are primarily originated to finance income-producing properties throughout the northeastern states. The underlying cash flows generated by the properties may be adversely impacted by a downturn in the economy as evidenced by increased vacancy rates, which in turn, may have an effect on the credit quality in this segment. Management generally obtains rent rolls and other financial information, as appropriate on an annual basis and continually monitors the cash flows of these loans. Construction loans – Loans in this segment include commercial construction loans, real estate subdivision development loans to developers, licensed contractors and builders for the construction and development of commercial real estate projects and residential properties. Construction lending contains a unique risk characteristic as loans are originated under market and economic conditions that may change between the time of origination and the completion and subsequent purchaser financing of the property. In addition, construction subdivision loans and commercial and residential construction loans to contractors and developers entail additional risks as compared to single-family residential mortgage lending to owner-occupants. These loans typically involve large loan balances concentrated in single borrowers or groups of related borrowers. Real estate subdivision development loans to developers, licensed contractors and builders are generally speculative real estate development loans for which payment is derived from sale of the property. Credit risk may be affected by cost overruns, time to sell at an adequate price, and market conditions. Construction financing is generally considered to involve a higher degree of credit risk than longer-term financing on improved, owner-occupied real estate. Residential construction credit quality may be impacted by the overall health of the economy, including unemployment rates and housing prices. Commercial – Loans in this segment are made to businesses and are generally secured by assets of the business. Repayment is expected from the cash flows of the business. A weakened economy, and resultant decreased consumer spending, will have an effect on the credit quality in this segment. Home equity line of credit – Loans in this segment include home equity loans and lines of credit underwritten with a loan-to-value ratio generally limited to no more than 80%, including any first mortgage. Our home equity lines of credit have a 9 year 10 month draw period followed by a 20 year amortization period and adjustable rates of interest which are indexed to the prime rate. The overall health of the economy, including unemployment rates and housing prices, may have an effect on the credit quality in this segment. Installment, Collateral, Demand, Revolving Credit and Resort – Loans in these segments include loans principally to customers residing in our primary market area with acceptable credit ratings. Our installment and collateral consumer loans generally consist of loans on new and used automobiles, loans collateralized by deposit accounts and unsecured personal loans. The overall health of the economy, including unemployment rates and housing prices, may have an effect on the credit quality in this segment. Excluding collateral loans which are fully collateralized by a deposit account, repayment for loans in these segments is dependent on the credit quality of the individual borrower. The resort portfolio consists of a direct receivable loan outside the Northeast which is amortizing to its contractual obligations. The Company has exited the resort financing market with a residual portfolio remaining. Allocated component: The allocated component relates to loans that are classified as impaired. Impairment is measured on a loan by loan basis for commercial real estate, construction, commercial and resort loans by the present value of expected cash flows discounted at the effective interest rate; the fair value of the collateral, if applicable; or the observable market price for the loan. 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. The Company does not separately identify individual consumer and residential real estate loans for impairment disclosures, unless such loans are subject to a troubled debt restructuring agreement or they are nonaccrual loans with outstanding balances greater than $100,000. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and construction loans by the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. Management updates the analysis quarterly. The assumptions used in appraisals are reviewed for appropriateness. Updated appraisals or valuations are obtained as needed or adjusted to reflect the estimated decline in the fair value based upon current market conditions for comparable properties. The Company periodically may agree to modify the contractual terms of loans. When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a troubled debt restructuring ("TDR"). All TDRs are classified as impaired. Unallocated component: An unallocated component is maintained, when needed, 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. The Company’s Loan Policy allows management to utilize a high and low range of 0.0% to 5.0% of our total allowance for loan losses when establishing an unallocated allowance, when considered necessary. The unallocated allowance is used to provide for an unidentified loss that may exist in emerging problem loans that cannot be fully quantified or may be affected by conditions not fully understood as of the balance sheet date. There was no unallocated allowance at December 31, 2016 and 2015.
Troubled Debt Restructuring	Troubled Debt Restructuring A loan is considered a troubled debt restructuring (“TDR”) when the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower in modifying or renewing the loan the Company would not otherwise consider. In connection with troubled debt restructurings, terms may be modified to fit the ability of the borrower to repay in line with their current financial status, which may include a reduction in the interest rate to market rate or below, a change in the term or movement of past due amounts to the back-end of the loan or refinancing. A loan is placed on non-accrual status upon being restructured, even if it was not previously, unless the modified loan was current for the six months prior to its modification and we believe the loan is fully collectable in accordance with its new terms. The Company’s policy to restore a restructured loan to performing status is dependent on the receipt of regular payments, generally for a period of six months and one calendar year-end. All troubled debt restructurings are classified as impaired loans and are reviewed for impairment by management on a quarterly basis per Company policy.
Mortgage Servicing Rights	Mortgage Servicing Rights The Company capitalizes mortgage servicing rights for loans originated and then sold with servicing retained based on the fair market value on the origination date. Mortgage servicing rights are amortized in proportion to and over the period of estimated net servicing income and such amortization is included in the consolidated statements of income as a reduction of mortgage servicing fee income. Mortgage servicing rights are evaluated for impairment by comparing their aggregate carrying amount to their fair value. An independent appraisal of the fair value of the Company’s mortgage servicing rights is obtained quarterly and is used by management to evaluate the reasonableness of the fair value estimates. Management reviews the independent appraisal and performs procedures to determine appropriateness. Impairment is recognized as an adjustment to mortgage servicing rights and mortgage servicing income.
Foreclosed Real Estate	Foreclosed Real Estate Real estate acquired through foreclosure comprises properties acquired in partial or total satisfaction of problem loans. The properties are acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. At the time these properties are foreclosed, the properties are initially recorded at the fair value at the date of foreclosure less estimated selling costs. Losses arising at the time of acquisition of such properties are charged against the allowance for loan losses. Subsequent loss provisions are charged to the foreclosed real estate valuation allowance and expenses incurred to maintain the properties are charged to noninterest expense. Properties are evaluated regularly to ensure the recorded amounts are supported by current fair values, and a charge to operations is recorded as necessary to reduce the carrying amount to fair value less estimated costs to dispose. Revenue and expense from the operation of other real estate owned and the provision to establish and adjust valuation allowances are included in noninterest expenses. Costs relating to the development and improvement of the property are capitalized, subject to the limit of fair value of the collateral. In the Consolidated Statements of Financial Condition, total prepaid expenses and other assets include foreclosed real estate of $-0- and $279,000 as of December 31, 2016 and 2015, with no specific valuation allowance. The recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process according to local requirements of the applicable jurisdiction totaled $4.3 million at December 31, 2016.
Bank Owned Life Insurance	Bank Owned Life Insurance Bank owned life insurance ("'BOLI") represents life insurance on certain employees who have consented to allow the Company to be the beneficiary of those policies. BOLI is recorded as an asset at cash surrender value. Increases in the cash value of the policies, as well as insurance proceeds received, are recorded in other non-interest income and are not subject to income tax.
Premises and Equipment	Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets, which range from three to ten years for furniture and equipment and five to forty years for premises. Leasehold improvements are amortized on a straight-line basis over the term of the respective leases, including renewal options, or the estimated useful lives of the improvements, whichever is shorter. Maintenance and repairs are charged to non-interest expense as incurred, while significant improvements are capitalized.
Derivative Financial Instruments	Derivative Financial Instruments Interest rate swap derivatives not designated as hedges are offered to certain qualifying commercial customers and to manage the Company’s exposure to interest rate movements and do not meet the hedge accounting parameters under FASB ASC 815 “Derivatives and Hedging”. Derivative financial instruments are recognized as assets and liabilities on the consolidated balance sheet and measured at fair value. Changes in the fair value of derivatives not designated in hedging relationships are recognized directly in earnings.
Pension and Other Postretirement Benefit Plans	Pension and Other Postretirement Benefit Plans The Company’s non-contributory defined-benefit pension plan and certain defined benefit postretirement plans were frozen as of February 28, 2013 and no additional benefits will accrue. The Company has a non-contributory defined benefit pension plan that provides benefits for substantially all employees hired before January 1, 2007 who meet certain requirements as to age and length of service. The benefits are based on years of service and average compensation, as defined in the Plan Document. The Company’s funding practice is to meet the minimum funding standards established by the Employee Retirement Income Security Act of 1974. In addition to providing pension benefits, we provide certain health care and life insurance benefits for retired employees. Participants or eligible employees hired before January 1, 1993 become eligible for the benefits if they retire after reaching age 62 with fifteen or more years of service. A fixed percent of annual costs are paid depending on length of service at retirement. The Company accrues for the estimated costs of these other post-retirement benefits through charges to expense during the years that employees render service. The Company makes contributions to cover the current benefits paid under this plan. The Company believes the policy for determining pension and other post-retirement benefit expenses is critical because judgments are required with respect to the appropriate discount rate, rate of return on assets and other items. The Company reviews and updates the assumptions annually. If the Company’s estimate of pension and post-retirement expense is too low it may experience higher expenses in the future, reducing its net income. If the Company’s estimate is too high, it may experience lower expenses in the future, increasing its net income.
Repurchase Liabilities	Repurchase Liabilities Repurchase agreements are accounted for as secured borrowings since the Company maintains effective control over the transferred securities and the transfer meets the other criteria for such accounting. Securities are sold to a counterparty with an agreement to repurchase the same or substantially the same security at a specified price and date. The Company has repurchase agreements with commercial or municipal customers that are offered as a commercial banking service. Customer repurchase agreements are for a term of one day and are backed by the purchasers’ interest in certain U.S. Treasury Bills or other U.S. Government securities. Obligations to repurchase securities sold are reflected as a liability in the Consolidated Statements of Financial Condition. The Company does not record transactions of repurchase agreements as sales. The securities underlying the repurchase agreements remain in the available-for-sale investment and held-for-maturity securities portfolios.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of an entire financial asset, a group of entire financial assets, or a participating interest in an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets. During the normal course of business, the Company may transfer a portion of a financial asset, for example, a participation loan or the government guaranteed portion of a loan. In order to be eligible for sales treatment, the transfer of the portion of the loan must meet the criteria of a participating interest. If it does not meet the criteria of a participating interest, the transfer must be accounted for as a secured borrowing. In order to meet the criteria for a participating interest, all cash flows from the loan must be divided proportionately, the rights of each loan holder must have the same priority, the loan holders must have no recourse to the transferor other than standard representations and warranties and no loan holder has the right to pledge or exchange the entire loan.
Fee Income	Fee Income Fee income for customer services which are not deferred are recorded on an accrual basis when earned.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred.
Income Taxes	Income Taxes Deferred income taxes are provided for differences arising in the timing of income and expenses for financial reporting and for income tax purposes. Deferred income taxes and tax benefits are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company provides a deferred tax asset valuation allowance for the estimated future tax effects attributable to temporary differences and carryforwards when realization is determined not to be more likely than not. FASB ASC 740-10 prescribes a recognition threshold that a tax position is required to meet before being recognized in the financial statements and provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition issues. Pursuant to FASB ASC 740-10, the Company examines its financial statements, its income tax provision and its federal and state income tax returns and analyzes its tax positions, including permanent and temporary differences, as well as the major components of income and expense to determine whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. The Company recognizes interest and penalties arising from income tax settlements as part of its provision for income taxes.
Employee Stock Ownership Plan ("ESOP")	Employee Stock Ownership Plan (“ESOP”) The Company accounts for its ESOP in accordance with FASB ASC 718-40, “Compensation – Stock Compensation”. Under this guidance, unearned ESOP shares are not considered outstanding and are shown as a reduction of stockholders' equity as unearned compensation. The Company will recognize compensation cost equal to the fair value of the ESOP shares during the periods in which they are committed to be released. To the extent that the fair value of the Company's ESOP shares differs from the cost of such shares, this difference will be credited or debited to equity. The Company will receive a tax deduction equal to the cost of the shares released to the extent of the principal pay down on the loan by the ESOP. As the loan is internally leveraged, the loan receivable from the ESOP to the Company is not reported as an asset nor is the debt of the ESOP shown as a liability in the Company's consolidated financial statements.
Stock Incentive Plan	Stock Incentive Plan In May 2016, the Company’s shareholders approved the First Connecticut Bancorp, Inc. 2016 Stock Incentive Plan (the “2016 Plan”). The Company has not issued any shares from the 2016 Plan as of December 31, 2016. During August 2012, the Company implemented the First Connecticut Bancorp, Inc. 2012 Stock Incentive Plan to provide for issuance or granting of shares of common stock for stock options or restricted stock. The Company applies ASC 718, Compensation – “Stock Compensation”, and has recorded stock-based employee compensation cost using the fair value method. Management estimated the fair values of all option grants using the Black-Scholes option-pricing model. Management estimated the expected life of the options using the simplified method allowed under SAB No. 107. The risk-free rate was determined utilizing the treasury yield for the expected life of the option contract.
Earnings Per Share	Earnings Per Share Earnings per common share is computed under the two-class method. Basic earnings per common share is computed by dividing net earnings allocated to common stockholders by the weighted-average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Non-vested restricted stock awards are participating securities as they have non-forfeitable rights to dividends or dividend equivalents. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock options for common stock using the treasury stock method. Unallocated common shares held by the ESOP are not included in the weighted-average number of common shares outstanding for purposes of calculating both basic and diluted earnings per common share. A reconciliation of the weighted-average shares used in calculating basic earnings per common share and the weighted-average common shares used in calculating diluted earnings per common share is provided in Note 3 - Earnings Per Share.
Segment Reporting	Segment Reporting The Company’s only business segment is Community Banking. For the years ended December 31, 2016, 2015 and 2014, this segment represented all the revenues and income of the consolidated group and therefore is the only reported segment as defined by FASB ASC 820, “Segment Reporting”.
Reclassifications	Reclassifications Amounts in prior period consolidated financial statements are reclassified whenever necessary to conform to the current year presentation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” ASU 2014-15 provides guidance in accounting principles generally accepted in the United States of America about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company adopted ASU 2014-15 and it had no impact on its financial statements. In August 2015, the FASB issued ASU No. 2015-14 "Revenue from Contracts with Customers (Topic 606)." In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606), with an original effective date for annual reporting periods beginning after December 15, 2016. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. ASU 2015-14 deferred the effective date of ASU 2014-09 to annual periods and interim periods within those annual periods beginning after December 15, 2017. The amendments can be applied retrospectively to each prior reporting period or retrospectively with the cumulative effect of initially applying this Update recognized at the date of initial application. Early application is not permitted. The Company is assessing the impact of ASU 2015-14 on its accounting and disclosures. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments—Overall (Topic 825-10): "Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01 amends the guidance on the classification and measurement of financial instruments. Some of the amendments in ASU 2016-01 include the following: 1) requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; 2) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; 3) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; and 4) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value; among others. For public business entities, the amendments of ASU 2016-01 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is assessing the impact of ASU 2016-01 on its accounting and disclosures. In February 2016, the FASB issued ASU No. 2016-02 "Leases (Topic 842)." ASU 2016-02 supersedes Topic 840, Leases. This ASU is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Some of the provisions in ASU 2016-02 include the following: 1) requires lessees to recognize a right-of-use asset and a lease liability for virtually all of their leases (other than leases that meet the definition of a short-term lease), 2) requires lessor accounting to be updated to align with certain changes to the lessee model and the new revenue recognition standard, 3) an arrangement contains an embedded lease if property, plant, or equipment is explicitly or implicitly identified and its use is controlled by the customer, 4) in certain circumstances, the lessee is required to remeasure the lease payments, and 5) requires extensive quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of revenue and expense recognized and expected to be recognized from existing contracts. For public business entities, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is assessing the impact of ASU 2016-02 on its accounting and disclosures. In March 2016, the FASB issued ASU No. 2016-07 "Investments – Equity Method and Joint Ventures (Topic 323) Simplifying the Transition to the Equity Method of Accounting." This ASU eliminates the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. For public business entities, ASU 2016-07 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. The Company is assessing the impact of ASU 2016-07 on its accounting and disclosures. In March 2016, the FASB issued ASU No. 2016-09 “Compensation - Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting.” This ASU requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. It also allows an employer to repurchase more of an employee’s shares than it can today for tax withholding purposes without triggering liability accounting and to make a policy election for forfeitures as they occur. For public business entities, ASU No. 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The Company is assessing the impact of ASU 2016-09 on its accounting and disclosures. In June 2016, the FASB issued ASU No. 2016-13 "Financial Instruments - Credit Losses (Topic 326)" requires an entity to utilize a new impairment model known as the current expected credit loss ("CECL") model to estimate its lifetime "expected credit loss" and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses. This ASU also requires new disclosures for financial assets measured at amortized cost, loans and available-for-sale debt securities. ASU 2016-13 is effective for public business entities for annual periods beginning after December 13, 2019, including interim periods within those fiscal years. Entities will apply the standard's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The Company is assessing the impact of ASU 2016-13 on its accounting and disclosures. In August 2016, the FASB issued ASU No. 2016-15 “Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments.” ASU 2016-15 provides cash flow statement classification guidance for certain transactions including how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The guidance is effective for public business entities for annual years beginning after December 15, 2017, and interim periods within those fiscal years and should be applied retrospectively. Early adoption is permitted, including adoption in an interim period. The Company is assessing the impact of ASU 2016-15 on its accounting and disclosures.
