NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business SI Financial Group, Inc. (the “Company”) is the holding company for Savings Institute Bank and Trust Company (the “Bank”). Established in 1842 , the Bank is a community-oriented financial institution headquartered in Willimantic, Connecticut. The Bank provides a variety of financial services to individuals, businesses and municipalities through its 23 offices in eastern Connecticut and Rhode Island. Its primary products include savings, checking and certificate of deposit accounts, residential and commercial mortgage loans, commercial business loans, construction loans and consumer loans. The Company does not conduct any material business other than owning all of the stock of the Bank and making payments on the subordinated debentures held by the Company. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company, its wholly-owned subsidiary, the Bank, and the Bank’s wholly-owned subsidiaries, SI Mortgage Company and SI Realty Company, Inc. All significant intercompany accounts and transactions have been eliminated. Basis of Financial Statement Presentation The consolidated financial statements have been prepared in accordance with GAAP and general practices within the banking industry. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities, as of the date of the balance sheets and reported amounts of revenues and expenses for the years presented. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, deferred income taxes and the impairment of long-lived assets. Reclassifications Certain amounts in the Company’s prior year consolidated financial statements were reclassified to conform to the current year presentation. Such reclassifications had no effect on net income. Significant Group Concentrations of Credit Risk A majority of the Company’s activities are with customers located within eastern Connecticut and Rhode Island. The Company does not have any significant concentrations in any one industry or customer. See Notes 3 and 4 for details relating to the Company’s investment and lending activities. Cash and Cash Equivalents and Statements of Cash Flows Cash and due from banks, federal funds sold and short-term investments with maturities at the date of purchase of less than 90 days are recognized as cash equivalents in the statements of cash flows. Federal funds sold generally mature in one day. For purposes of reporting cash flows, the Company considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. Cash flows from loans and deposits are reported on a net basis. The Company maintains amounts due from banks and federal funds sold that, at times, may exceed federally insured limits. The Company has not experienced any losses from such concentrations. Fair Value Hierarchy The Company groups its assets and liabilities in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1 – Valuation is based on quoted prices in active markets for identical assets or liabilities. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 – Valuation is based on 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 for substantially the full term of the assets or liabilities. Level 3 – Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include assets or liabilities whose value is determined using unobservable inputs to pricing models, discounted cash flow methodologies, or similar techniques, as well as assets or liabilities for which the determination of fair value requires significant management judgment or estimation. Transfers between levels are recognized at the end of a reporting period, if applicable. Securities Management determines the appropriate classification of securities at the date individual securities are acquired, and the appropriateness of such classification is reassessed at each reporting date. Debt securities that management has the positive intent and ability to hold to maturity are classified as “held to maturity” and recorded at amortized cost. Securities that are held principally for trading in the near term are classified as “trading securities.” Trading securities are carried at fair value, with unrealized gains and losses recognized in earnings. Interest and dividends are included in net interest income. Securities not classified as held to maturity or trading, including equity securities with readily determinable fair values, are classified as “available for sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive loss, net of taxes. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. At each reporting period, the Company evaluates securities with a decline in fair value below the amortized cost of the investment to determine whether or not the impairment is deemed to be other than temporary. The evaluation is based upon factors such as the creditworthiness of the issuers/guarantors, the underlying collateral, if applicable, and the continuing performance of the securities. Management also evaluates other facts and circumstances that may be indicative of an other-than-temporary impairment ("OTTI") condition, such as the type of security, length of time and extent to which the fair value has been less than cost and near-term prospects of the issuers. OTTI is required to be recognized if (1) the Company intends to sell the security; (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) for debt securities, the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. For impaired debt securities that the Company intends to sell, or more likely than not will be required to sell, the full amount of the depreciation is recognized as OTTI through earnings. For all other impaired debt securities, credit-related OTTI is recognized through earnings and noncredit-related OTTI is recognized in other comprehensive loss, net of applicable taxes. See Notes 3 and 15 for more details. Federal Home Loan Bank Stock The Bank, as a member of the FHLB, is required to maintain an investment in the capital stock of the FHLB. The stock has no quoted market value and is carried at cost. At its discretion, the FHLB may declare dividends on its stock. The stock is redeemable at par by the FHLB and the Company’s ability to redeem the shares owned is dependent on the redemption practices of the FHLB. The Company reviews its investment in FHLB stock for impairment based on the ultimate recoverability of the cost basis in the FHLB stock. No impairment charges were recognized for the years ended December 31, 2018 , 2017 or 2016 . Federal Reserve Bank Stock The Bank, as a member of the FRB, is required to maintain an investment in capital stock of the FRB. The stock has no quoted market value and is carried at cost. The Company reviews its investment in FRB stock for impairment based on the ultimate recoverability of the cost basis in FRB stock. No impairment charges were recognized for the years ended December 31, 2018 , 2017 or 2016 . 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 noninterest 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 and reported within mortgage banking activities on the accompanying consolidated statements of income. Loans Receivable Loans receivable are stated at current unpaid principal balances, net of the allowance for loan losses and deferred loan origination fees and costs. Management has the ability and intent to hold its loans receivable for the foreseeable future or until maturity or pay-off. A loan is impaired when, based on current information and events, it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the 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. Impairment is measured on a loan by loan basis for residential and commercial mortgage loans and commercial business loans by either the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not typically identify individual consumer loans for impairment disclosures unless such loans are subject to a troubled debt restructuring (“TDR”) agreement. The Company periodically may agree to modify the contractual terms of loans. When a loan is modified and concessions have been made to the original contractual terms due to the borrower's financial condition that would not otherwise be considered for a borrower with similar risk characteristics such as reductions of interest rates, deferral of interest or principal payments or maturity extensions, the modification is considered a TDR. Modified terms are dependent upon the financial position and needs of the individual borrower. If the modification agreement is violated, the loan is handled by the Company’s Collections Department for resolution, which may result in foreclosure. Allowance for Loan Losses The allowance for loan losses, a material estimate which could change significantly in the near-term, is established through a provision for loan losses charged to earnings to account for losses that are inherent in the loan portfolio and estimated to occur, and is maintained at a level management considers adequate to absorb losses in the loan portfolio. Loan losses are charged against the allowance for loan losses when management believes the uncollectibility of the principal loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance for loan losses when received. Management's judgment in determining the adequacy of the allowance is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance for loan losses is evaluated on a monthly basis by management and is based on the evaluation of the known and inherent risk characteristics and size and composition of the loan portfolio, the assessment of current economic and real estate market conditions, adverse situations that may affect a borrower’s ability to repay, estimated value of any underlying collateral, historical loan loss experience, the amount and trends of nonperforming loans, delinquencies, classified assets and loan charge-offs and evaluations of loans and other relevant factors. The allowance for loan losses consists of the following key elements: ◦ Specific allowance for identified impaired loans . For loans identified as impaired, an allowance is established when the present value of expected cash flows (or observable market price of the loan or fair value of the collateral if the loan is collateral dependent) of the impaired loan is lower than the carrying value of that loan. In the determination of the specific allowance for loan losses, management may obtain independent appraisals for significant properties, when necessary. ◦ General valuation allowance. The general component represents a valuation allowance on the remainder of the loan portfolio, after excluding impaired loans. For this portion of the allowance, loans are segregated by category and assigned an allowance percentage based on historical loan loss experience adjusted for qualitative factors stratified by the following loan segments: residential one- to four-family, multi-family and commercial real estate, construction, commercial business and consumer. Management uses a rolling average of historical losses based on the time frame appropriate to capture relevant loss data for each loan segment. This historical loss factor is adjusted for the following qualitative factors: changes in lending policies and procedures, including changes in underwriting standards and collections, charge-off and recovery practices; changes in national, regional and local economic and business conditions and developments that affect the collectibility of the portfolio, including the condition of various market segments; changes in the size and composition of the loan portfolio and in the terms of the loans; changes in the experience, ability and depth of lending and underwriting management and other relevant staff; changes in the volume and severity of past due loans, the volume of nonaccrual loans and the volume and severity of adversely classified or graded loans; changes in the quality of the loan review system; changes in the underlying collateral for collateral-dependent loans; the existence and effect of any concentrations of credit and changes in the level of such concentrations; the effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the portfolio. The qualitative factors are determined based on the following various risk characteristics for each loan segment. Risk characteristics relevant to each portfolio segment are as follows: Residential – One- to Four-Family – The Bank primarily originates conventional loans with loan-to-value ratios less than 95% and generally originates loans with loan-to-value ratios in excess of 80% only when secured by first liens on owner-occupied one- to four-family residences. Loans with loan-to-value ratios in excess of 80% generally require private mortgage insurance or additional collateral. All loans in this segment are collateralized by owner-occupied residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality of this segment. Multi-family and Commercial – Loans in this segment are originated to acquire, develop, improve or refinance multi-family and commercial real estate where the property is the primary collateral securing the loan, and the income generated from the property is the primary repayment source. The underlying cash flows generated by the properties can be impacted by the economy as evidenced by increased vacancy rates. Payments on loans secured by income-producing properties often depend on the successful operation and management of the properties. Management continually monitors the cash flows of these loans. Construction – This segment includes loans to individuals, and to a lesser extent builders, to finance the construction of residential dwellings. The Bank also originates construction loans for commercial development projects. Upon the completion of construction, the loan generally converts to a permanent mortgage loan. Credit risk is affected by cost overruns, whether estimates of the sale price of the property are correct, the time it takes to sell at an adequate price and market conditions. Commercial Business – 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 reduced viability of the industry in which the customer operates will have a negative impact on the credit quality in this segment. The Bank provides loans to investors in the time share industry, which are secured by consumer receivables, and provides loans for capital improvements to condominium associations, which are secured by the assigned rights to levy special assessments to condominium owners. Additionally, the Bank purchases loans primarily out of our market area from a company specializing in medical loan originations, which are secured by medical equipment. Consumer – Loans in this segment primarily include home equity lines of credit (representing both first and second liens) and, to a lesser extent, loans secured by marketable securities, passbook or certificate accounts, motorcycles, automobiles and recreational vehicles, as well as unsecured loans. Consumer loan collections depend on the borrower’s continuing financial stability, and therefore, are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy. In computing the allowance for loan losses, we do not assign a general valuation allowance to the Small Business Administration ("SBA") and United States Department of Agriculture ("USDA") loans that we purchase as such loans are fully guaranteed. These loans are included in commercial business loans. The majority of the Company's loans are collateralized by real estate located in eastern Connecticut and Rhode Island. To a lesser extent, certain commercial real estate loans are secured by collateral located outside of our primary market area, with concentrations in Massachusetts and New Hampshire. Accordingly, the collateral value of a substantial portion of the Company's loan portfolio and real estate acquired through foreclosure is susceptible to changes in local market conditions. Although management believes it uses the best information available to establish the allowance for loan losses, future adjustments to the allowance for loan losses may be necessary and the Company’s results of operations could be adversely affected if circumstances differ substantially from the assumptions used in making the determinations. Furthermore, while management believes it has established the allowance for loan losses in conformity with GAAP, our regulators, in reviewing the loan portfolio, may request us to increase our allowance for loan losses based on judgments different from ours. In addition, because future events affecting borrowers and collateral cannot be predicted with certainty, the existing allowance for loan losses may not be adequate or increases may be necessary should the quality of any loans deteriorate as a result of the factors discussed above. Any material increase in the allowance for loan losses would adversely affect the Company’s financial condition and results of operations. Loans Acquired with Deteriorating Credit Quality Loans acquired in a transfer, including business combinations, where there is evidence of credit deterioration since origination and it is probable at the date of acquisition the Company will not collect all contractually required principal and interest payments, are accounted for under accounting guidance for purchased credit-impaired loans. Applicable guidance provides that the excess of the cash flows initially expected to be collected over the fair value of the loans at the acquisition date (i.e., the accretable yield) is accreted into interest income over the estimated remaining life of the loans, provided that the timing and amount of future cash flows is reasonably estimable. Such loans are considered to be accruing because their interest income relates to the accretable yield and not to contractual interest payments. The difference between the contractually required payments and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference. Subsequent to acquisition, probable decreases in expected cash flows are recognized through a provision for loan losses, resulting in an increase to the allowance for loan losses. If the Company has probable and significant increases in cash flows expected to be collected, the Company will first reverse any previously established allowance for loan losses and then increase interest income as a prospective yield adjustment. Interest and Fees on Loans Interest on loans is accrued and included in net interest income based on contractual rates applied to principal amounts outstanding. Accrual of interest is discontinued when loan payments are 90 days or more past due, based on contractual terms, or when, in the judgment of management, collectibility of the loan or loan interest becomes uncertain. Subsequent recognition of income occurs only to the extent payment is received subject to management's assessment of the collectibility of the remaining interest and principal. A nonaccrual loan is restored to accrual status when it is no longer delinquent and collectibility of interest and principal is no longer in doubt and the borrower has made regular payments in accordance with the terms of the loan over a period of at least six months. Interest collected on nonaccrual loans is recognized only to the extent cash payments are received, and may be recorded as a reduction to principal if the collectibility of the principal balance of the loan is unlikely. Loan origination fees, direct loan origination costs and loan purchase premiums are deferred and the net amount is recognized as an adjustment of the related loan's yield utilizing the interest method over the contractual life of the loan. In addition, discounts related to fair value adjustments for loans receivable acquired in a business combination or asset purchase are accreted into earnings over the contractual term as an adjustment of the related loan's yield. The Company periodically evaluates the cash flows expected to be collected for loans acquired with deteriorated credit quality. Changes in the expected cash flows compared to the expected cash flows as of the date of acquisition may impact the accretable yield or result in a charge to the provision for loan losses to the extent of a shortfall. Derivative Instruments Not Designated As Hedging Instruments Certain derivative instruments do not meet the requirements to be accounted for as hedging instruments. These undesignated derivative instruments are recognized on the consolidated balance sheets at fair value, with changes in fair value recorded in other noninterest income. Interest Rate Swap Agreements - 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 to manage the Company's exposure to interest rate movements but do not meet the strict hedge accounting as defined by the Financial Accounting Standards Board ("FASB") (Topic 815) per "Derivatives and Hedging." The interest rate swap agreement enables the customer to synthetically fix the interest rate on a variable rate loan. The customer pays a variable rate and enters 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 agreements with our customers are cross-collateralized by the loan collateral and do not have any embedded interest rate caps or floors. For every variable rate loan and fixed rate swap agreement entered into with a commercial customer, the Company simultaneously enters into an offsetting fixed rate swap agreement with a correspondent bank, agreeing to pay a fixed payment and receive a variable interest rate swap. The Company is party to master netting agreements with its correspondent bank; 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. Derivative Loan Commitments - Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. Loan commitments that are derivatives are recognized at fair value on the consolidated balance sheets in other assets and other liabilities with changes in their fair values recorded in mortgage banking within noninterest income. Forward Loan Sale Commitments - To protect against the price risk inherent in the exercise of derivative loan commitments, the Company utilizes both “mandatory delivery” and "best efforts" forward loan sale commitments. Mandatory delivery contracts and best efforts contracts are accounted for as derivative instruments. Mandatory and best efforts delivery forward loan sale commitments are recognized at fair value on the consolidated balance sheets in other assets and other liabilities with changes in their fair values recorded in mortgage banking within noninterest income. Transfers of Financial Assets Transfers of financial assets 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 no condition both constrains the transferee from taking advantage of that right and provides more than a trivial benefit for the transferor and (3) the transferor does not maintain effective control over the transferred assets through either (a) an agreement that both entitles and obligates the transferor to repurchase or redeem the assets before maturity or (b) the ability to unilaterally cause the holder to return specific 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. Other Real Estate Owned Other real estate owned consists of properties acquired through, or in lieu of, loan foreclosure or other proceedings and is initially recorded at fair value at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, the properties are held for sale and are carried at the lower of carrying amount or fair value less estimated costs of disposal. Any write-down to fair value at the time of acquisition is charged to the allowance for loan losses. 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. Gains or losses are included in noninterest expenses upon disposal. Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is charged to operations using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the estimated economic lives of the improvements or the expected lease terms. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured. The estimated useful lives of the assets are as follows: Classification Estimated Useful Lives Buildings 5 to 40 years Furniture and equipment 3 to 10 years Leasehold improvements 5 to 20 years Gains and losses on dispositions are recognized upon realization. Maintenance and repairs are expensed as incurred and improvements are capitalized. Bank-owned Life Insurance Bank-owned life insurance policies are presented on the consolidated balance sheets at cash surrender value. Changes in cash surrender value, as well as gains on the surrender of policies, are reflected in noninterest income in the consolidated statements of income and are not subject to income taxes. See Note 11 for additional discussion. Servicing The Company services mortgage loans for others. Mortgage servicing assets are recognized as separate assets at fair value when rights are acquired through purchase or retained through the sale of loans. Fair value is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Capitalized servicing rights are reported in other assets and are amortized into mortgage banking income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to the amortized cost. Impairment is determined by stratifying rights by predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual stratum, to the extent that the fair value is less than the capitalized amount for the stratum. Changes in the valuation allowance are reported in loan servicing fee income. Servicing fee income is recorded for fees earned for servicing loans, which is included in mortgage banking income. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Impairment of Long-lived Assets Long-lived assets, including premises and equipment and certain identifiable intangible assets that are held and used by the Company, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If impairment is indicated by that review, the asset is written down to its estimated fair value through a charge to earnings. Goodwill is measured as the excess of the cost of a business combination over the sum of the amounts assign

At December 31, 2018 and 2017 , U.S. government and agency obligations, government-sponsored enterprise securities and mortgage-backed agency securities with an amortized cost of $36.2 million and $35.1 million , respectively, and a fair value of $35.8 million and $35.1 million , respectively, were pledged to secure public deposits and for other purposes required or permitted by law. The amortized cost and fair value of debt securities by contractual maturities at December 31, 2018 are presented below. Maturities are based on the final contractual payment dates, and do not reflect the impact of potential prepayments or early redemptions. Because mortgage-backed securities ("MBS") are not due at a single maturity date, they are not included in the maturity categories in the following maturity summary.

Among other things, the other-than-temporary impairment review of the investment securities portfolio focuses on the combined factors of percentage and length of time by which the issue is below book value, as well as consideration of issuer specific information (present value of cash flows expected to be collected, issuer rating changes and trends, credit worthiness and review of underlying collateral), broad market details and the Company’s intent to sell the security or if it is more likely than not the Company will be required to sell the debt security before recovering its cost. The Company also considers whether the depreciation is due to interest rates, market changes or credit risk. The services of an independent third-party are utilized by the Company to provide information used to assist in the impairment analysis. At December 31, 2018 , 76 debt securities with gross unrealized losses had aggregate depreciation of approximately 2.9% of the Company’s amortized cost basis. The majority of the unrealized losses related to the Company’s mortgage-backed securities. For the years ended December 31, 2018 , 2017 and 2016 , the Company recognized no impairment charges on investments deemed other-than-temporarily impaired. The following summarizes, by security type, the basis for management’s determination during the preparation of the financial statements of whether the applicable investments within the Company’s securities portfolio were other-than-temporarily impaired at December 31, 2018 . U.S. Government and Agency Obligations and Mortgage-backed Securities - Agency - Residential. The unrealized losses on the Company’s U.S. Government and agency obligations and mortgage-backed agency-residential securities related primarily to a widening of the rate spread to comparable treasury securities. The Company does not expect these securities to settle at a price less than the par value of the securities. Mortgage-backed Securities - Non-agency - Residential. The unrealized losses on the Company’s non-agency-residential mortgage-backed securities relate to one investment which has been evaluated by management and no potential credit loss was identified. Tax-exempt securities. The unrealized losses on the Company's tax-exempt securities relate to two investments in general obligation bonds. Interest on these bonds is paid by the Federal Government and there is a sinking fund for principal repayment, which is on schedule. The Company does not expect these securities to settle at a price less than par value.

The amounts transferred have been accounted for as sales and, therefore, are not included in the Company's accompanying consolidated balance sheets. The Company and participating lenders share ratably in cash flows and any gains or losses that may result from a borrower's lack of compliance with contractual terms of the loan. The Company continues to service the loans on behalf of the participating lenders and, as such, collects cash payments from the borrowers, remits payments (net of servicing fees) to participating lenders and disburses required escrow funds to relevant parties. At December 31, 2018 and 2017 , the Company was servicing loans for participations aggregating $9.5 million and $12.6 million , respectively. The Company purchased commercial loans totaling $56.0 million , $36.1 million and $37.7 million during 2018 , 2017 and 2016 , respectively.

The Company reviews and establishes, if necessary, an allowance for certain impaired loans for the amount by which the present value of expected cash flows (or observable market price of loan or fair value of the collateral if the loan is collateral dependent) are lower than the carrying value of the loan. For the periods presented, the Company concluded certain impaired loans required no valuation allowance as a result of management’s measurement of impairment. No additional funds are committed to be advanced to those borrowers whose loans are deemed impaired without prior approval of the Loan Committee or the Board of Directors.

There is a distinct possibility that the Company will sustain some loss if the weakness is not corrected. ◦ Doubtful (Rating 7): 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. ◦ Loss (Rating 8): Loans in this category are considered uncollectible and of such little value that their continuance as loans is not warranted. Management periodically reviews the ratings described above and the Company’s internal audit function reviews components of the credit files, including the assigned risk ratings, of certain commercial loans as part of its loan review.

The most common types of modifications include below market interest rate reductions, deferrals of principal and maturity extensions. Modified terms are dependent upon the financial position and needs of the individual borrower. If the modification agreement is violated, the loan is handled by the Company's Collections Department for resolution, which may result in foreclosure. The Company's determination of whether a loan modification is a TDR considers the individual facts and circumstances surrounding each modification. The Company's nonaccrual policy is followed for TDRs. If the loan was current prior to modification, nonaccrual status would not be required. If the loan was on nonaccrual prior to modification or if the payment amount significantly increases, the loan will remain on nonaccrual for a period of at least six months. Loans qualify for return to accrual status once the borrower has demonstrated the willingness and the ability to perform in accordance with the restructured terms of the loan agreement for a period of not less than six consecutive months. All TDRs are initially reported as impaired. The impaired classification may be removed after a year following the restructure if the borrower demonstrates compliance with the modified terms and the restructuring agreement specifies an interest rate equal to that which would be provided to a borrower with similar risk characteristics at the time of restructuring. The following table provides information on loans modified as TDRs during the years ended December 31, 2018 , 2017 and 2016 .

Residential Mortgage Loans Serviced for Others The Company services certain loans it has sold with and without recourse to third parties and other loans for which the Company acquired the servicing rights. Loans serviced for others are not included in the Company’s consolidated balance sheets.

The fair value of servicing rights was determined using a discount rate of 12.28% , prepayment speeds ranging from 80% to 274% and minimal anticipated credit losses. At December 31, 2018 , 2017 and 2016 , the aggregate of residential mortgage loans serviced for others amounted to $261.2 million , $235.8 million and $212.9 million , respectively.

Borrowings	BORROWINGS Federal Home Loan Bank Advances As a member of the FHLB, the Bank has access to a pre-approved secured line of credit with the FHLB of $10.0 million and the capacity to obtain additional advances up to a certain percentage of the value of its qualified collateral, as defined in the FHLB Statement of Credit Policy. FHLB advances are secured by qualified collateral, which is based on a percentage of its outstanding residential first mortgage loans. In accordance with an agreement with the FHLB, the qualified collateral must be free and clear of liens, pledges and encumbrances. At December 31, 2018 and 2017 , there were no advances outstanding under the line of credit. Other outstanding advances from the FHLB aggregated $151.8 million and $170.1 million at December 31, 2018 and 2017 , respectively, at interest rates ranging from 1.27% to 3.24% and 1.19% to 3.75% , respectively. Junior Subordinated Debt Owed to Unconsolidated Trust SI Capital Trust II (the “Trust”), a wholly-owned subsidiary of the Company, was formed on August 31, 2006. The Trust had no independent assets or operations, and was formed to issue $8.0 million of trust preferred securities and invest the proceeds thereof in an equivalent amount of junior subordinated debentures issued by the Company. The trust preferred securities mature in 2036 and bear interest at three-month LIBOR plus 1.70% . The Company may redeem the trust preferred securities, in whole or in part. The subordinated debt securities are unsecured obligations of the Company and are subordinate and junior in right of payment to all present and future senior indebtedness of the Company. The Company has entered into a guarantee, which together with its obligations under the subordinated debt securities and the declaration of trust governing the Trust, including its obligations to pay costs, expenses, debts and liabilities, other than trust securities, provides a full and unconditional guarantee of amounts on the capital securities. If the Company defers interest payments on the junior subordinated debt securities, or otherwise is in default of the obligations, the Company would be prohibited from making dividend payments to its shareholders. The contractual maturities of borrowings, by year, at December 31, 2018 are as follows: FHLB Advances Subordinated Debt Total (Dollars in Thousands) 2019 $ 44,269 $ — $ 44,269 2020 44,000 — 44,000 2021 31,318 — 31,318 2022 (1) 18,249 — 18,249 2023 8,000 — 8,000 Thereafter (2) 6,000 8,248 14,248 Total $ 151,836 $ 8,248 $ 160,084 Weighted average rate 2.04 % 4.49 % 2.17 % (1) Includes an FHLB advance of $4.0 million that is callable during 2019.

Amounts transferred to the reserve have been claimed as deductions from taxable income, and, if the reserve is used for purposes other than to absorb losses on loans, a federal income tax liability could be incurred. It is not anticipated the Company will incur a federal income tax liability relating to this reserve balance, and accordingly, deferred income taxes of approximately $987,000 at December 31, 2018 and 2017 have not been recognized. Financial service companies doing business in Connecticut are permitted to establish a “passive investment company” (“PIC”) to hold and manage loans secured by real property. PICs are exempt from Connecticut corporation business tax, and dividends received by the financial services companies from PICs are not taxable. In January 1999, the Bank established a PIC, as a wholly-owned subsidiary, and in June 2000, transferred a portion of its residential and commercial mortgage loan portfolios from the Bank to the PIC. A substantial portion of the Company’s interest income is now derived from the PIC, an entity whose net income is exempt from State of Connecticut taxes, and accordingly, state income taxes are minimal. The Bank’s ability to continue to realize the tax benefits of the PIC is subject to the PIC continuing to comply with all statutory requirements related to the operations of the PIC. Accordingly, no Connecticut-related deferred tax assets or liabilities have been recorded. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are expected to be deductible, management believes its deferred tax asset is more likely than not realizable. With limited exception, the Company is no longer subject to United States federal, state and local income tax examinations by the tax authorities for the years prior to 2015 .

Retirement Benefits [Abstract]
Compensation and Employee Benefit Plans [Text Block]	BENEFIT PLANS Defined Benefit Plan As a result of the Newport acquisition, the Company participates in the Pentegra Defined Benefit Plan for Financial Institutions (the "Pentegra DB Plan"), a tax-qualified defined benefit pension plan. The Pentegra DB Plan operates as a multi-employer plan for accounting purposes and as a multi-employer plan under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code. There are no collective bargaining agreements in place that require contributions to the Pentegra DB Plan. In connection with the Newport acquisition, the plan was frozen effective September 6, 2013 and the Company recorded a contingent obligation to settle the plan at some future date. At December 31, 2018 and 2017, the Company's recorded liability related to Newport's Pentegra DB Plan totaled $4.8 million and $4.7 million , respectively. The Pentegra DB Plan is a single plan under the Internal Revenue Code and, as a result, all of the assets stand behind all of the liabilities. Accordingly, under the Pentegra DB Plan contributions made by a participating employer may be used to provide benefits to participants of other participating employers. The funded status (market value of plan assets divided by funding target) of the Pentegra DB Plan, as of July 1, 2018 was 80.22% per the valuation reports. Market value of plan assets reflects contributions received through June 30, 2018. The Bank's contributions to the Pentegra DB Plan are not more than 5% of the total contributions to the Pentegra DB Plan. During the years ended December 31, 2018 , 2017 and 2016 , contributions of $152,000 , $282,000 and $356,000 , respectively, were paid by the Bank. The Bank recognized pension expense of $250,000 , $240,000 and $222,000 under the plan for the years ended December 31, 2018 , 2017 and 2016 , respectively. Defined Contribution Plan The Bank’s Profit Sharing and 401(k) Savings Plan (the “Plan”) is a tax-qualified defined contribution plan for the benefit of its eligible employees. The Bank’s profit sharing contribution to the Plan is a discretionary amount authorized by the Board of Directors, based on the financial results of the Bank. An employee’s share of the profit sharing contribution represents the ratio of the employee’s salary to the total salary expense of the Bank. Participants vest in the Bank’s discretionary profit sharing contributions based on years of service, with 100% vesting attained upon five years of service. There were no profit sharing contributions for the years ended December 31, 2018 , 2017 and 2016 . The Plan also includes a 401(k) feature. Eligible participants may make salary deferral contributions of up to 100% of earnings subject to Internal Revenue Services limitations. The Bank makes matching contributions equal to 50% of the participants’ contributions up to 6% of the participants’ earnings. Participants are immediately vested in their salary deferral contributions, employer matching contributions and earnings thereon. Bank contributions were $317,000 , $319,000 and $279,000 for the years ended December 31, 2018 , 2017 and 2016 , respectively. Group Term Replacement Plan The Bank maintains the Group Term Replacement Plan to provide a death benefit to executives designated by the Compensation Committee of the Board of Directors. The death benefits are funded through certain insurance policies that are owned by the Bank on the lives of the participating executives. The Bank pays the life insurance premiums, which fund the death benefits from its general assets, and is the beneficiary of any death benefits exceeding any executive’s maximum dollar amount specified in his or her split-dollar endorsement policy. The maximum dollar amount of each executive’s split-dollar death benefit equals three times the executive’s annual compensation less amount of pre-retirement life insurance benefit and three times final annual compensation post-retirement not to exceed a specified dollar amount. For purposes of the plan, annual compensation includes an executive’s base compensation, commissions and cash bonuses earned under the Bank’s bonus plan. Participation in the plan ceases if an executive is terminated for cause or the executive terminates employment for reasons other than death, disability or retirement. If the Bank wishes to maintain the insurance after a participant’s termination in the plan, the Bank will be the direct beneficiary of the entire death proceeds of the insurance policies. Total expense recognized under this plan was $215,000 , $155,000 and $13,000 for the years ended December 31, 2018 , 2017 and 2016 , respectively. Executive Supplemental Retirement Agreements – Defined Benefit The Bank maintains unfunded supplemental defined benefit retirement agreements with its directors and certain members of senior management, as well as certain former officers and directors of Newport. These agreements provide for supplemental retirement benefits to certain executives based upon average annual compensation and years of service. Entitlement of benefits commence upon the earlier of the executive’s termination of employment (other than for cause), at or after attaining age 65 or, depending on the executive, on the date when the executive’s years of service and age total 80 or 78. Total expense (income) incurred under these agreements for the years ended December 31, 2018 , 2017 and 2016 was $1.1 million , $517,000 and $(115,000) , respectively. The income recognized for 2016 resulted from a change in estimate due to the death of a beneficiary. Performance-Based Incentive Plan The Bank has an incentive plan whereby all employees are eligible to receive a bonus tied to both the Company and individual performance. Non-discretionary contributions to the plan require the approval of the Board of Directors’ Compensation Committee. Total expense recognized was $1.7 million , $1.5 million and $1.6 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. Supplemental Executive Retirement Plan The Bank maintains the Supplemental Executive Retirement Plan to provide restorative payments to executives, designated by the Board of Directors, who are prevented from receiving the full benefits of the Bank’s Profit Sharing and 401(k) Savings Plan and ESOP. The supplemental executive retirement plan also provides supplemental benefits to participants upon a change in control prior to the scheduled repayment of the ESOP loan. For the years ended December 31, 2018 , 2017 and 2016, the President and Chief Executive Officer and the Chief Operating Officer were designated by the Board of Directors to participate in the plan. For the year ended December 31, 2018 , the Chief Financial Officer was designated by the Board of Directors to participate in the Plan. Total expense incurred under this plan was $35,000 , $35,000 and $58,000 for the years ended December 31, 2018 , 2017 and 2016 , respectively. Employee Stock Ownership Plan In September 2004, the Bank established the ESOP for the benefit of its eligible employees. The Company provided a loan to the ESOP of $4.9 million which was used to purchase 492,499 shares of the Company’s outstanding stock. The loan bears interest equal to 4.75% and provides for annual payments of interest and principal over the 15 -year term of the loan. In January 2011, the Company completed an additional public stock offering. At that time, the Company provided an additional loan to the ESOP of $3.1 million , which was used to purchase 392,670 shares of the Company's common stock. The new loan bears interest equal to 3.25% and provides for annual payments of interest and principal over the 20 -year term of the loan. At December 31, 2018 , the remaining principal balance on the ESOP debt is payable as follows (in thousands) : 2019 $ 587 2020 152 2021 157 2022 162 2023 167 Thereafter 1,332 Total $ 2,557 The Bank has committed to make contributions to the ESOP sufficient to support the debt service of the loans. The loans are secured by the shares purchased, which are held in a suspense account for allocation among participants as the loans are repaid. Shares held by the ESOP include the following at December 31, 2018 and 2017 : December 31, 2018 2017 (Dollars In Thousands) Allocated 363,588 330,621 Committed to be allocated 48,638 48,638 Unallocated 264,611 313,249 Total shares 676,837 692,508 Fair value of unallocated shares $ 3,368 $ 4,605 Total compensation expense recognized in connection with the ESOP was $690,000 , $727,000 and $668,000 for the years ended December 31, 2018 , 2017 and 2016 , respectively. Equity Incentive Plan The Company's equity incentive plan consists of stock options and shares of restricted stock that may be granted to its employees, officers and directors. Both incentive stock options and non-statutory stock options may be granted under these plans. The 2012 Equity Incentive Plan allows the Company to grant up to 504,794 stock options and 201,918 shares of restricted stock. All options have a contractual life of 10 years and vest equally over a period of 5 years beginning on the first anniversary of the date of grant. Under the 2012 Equity Incentive Plan, both performance and time-based restricted stock awards may be granted. At December 31, 2018 , 87,014 stock options and 20,592 shares of restricted stock were available for future grants under the 2012 plan. For the years ended December 31, 2018 , 2017 and 2016 , the Company recognized share-based compensation expense related to the stock option and restricted stock awards of $205,000 , $381,000 and $882,000 , respectively. During the years ended December 31, 2018 and 2016 , the Company granted stock options totaling 20,000 and 20,000 , respectively. The Company did not grant any stock options during the year ended December 31, 2017. The fair value of each option was determined at the grant date using the Black-Scholes option pricing model with the following weighted average assumptions: 2018 2016 Expected term (years) 10.00 10.00 Expected dividend yield 1.60 % 1.44 % Expected volatility 60.72 57.13 Risk-free interest rate 2.65 1.75 Fair value of options granted $ 8.62 $ 7.75 The expected term was based on the estimated life of the stock options. The dividend yield assumption was based on the Company’s historical and expected dividend pay-outs. The expected volatility represents the Company’s historical volatility. The risk-free interest rate was based on the implied yields of U.S. Treasury zero-coupon issues for periods within the contractual life of the awards in effect at the time of the stock option grants. The following is a summary of activity for the Company’s stock options for the year ended December 31, 2018 : Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (in years) Options outstanding at beginning of year 428,900 $ 10.93 Options granted 20,000 14.85 Options exercised (166,443 ) 10.41 Options forfeited (4,996 ) 11.00 Options outstanding at end of year 277,461 11.52 5.22 Options exercisable at end of year 207,861 11.02 4.47 There were 166,443 , 54,362 and 7,892 options exercised during the years ended December 31, 2018, 2017 and 2016, respectively. The total intrinsic value of options exercised during the years ended December 31, 2018, 2017 and 2016, was $405,000 , $153,000 and $44,000 , respectively. The intrinsic value of stock options outstanding and exercisable at December 31, 2018 was $398,000 and $376,000 , respectively. At December 31, 2018, there was $394,000 of total unrecognized compensation costs related to outstanding stock options, which is expected to be recognized over a weighted average period of 1.5 years.

Shares Weighted Average Grant Date Fair Value Unvested restricted shares at beginning of year 600 $ 11.77 Restricted shares vested (300 ) 11.77 Restricted shares forfeited (300 ) 11.77 Unvested restricted shares at end of year — — The aggregate fair value of restricted stock awards that vested during the years ended December 31, 2018 , 2017 and 2016 was $4,000 , $606,000 and $511,000 , respectively. At December 31, 2018 , all restricted stock awards granted under the incentive plans have vested. Bank-Owned Life Insurance The Company has an investment in, and is the beneficiary of, life insurance policies on the lives of certain officers of SI Financial and former officers and directors of Newport. The purpose of these life insurance investments is to provide income through the appreciation in cash surrender value of the policies, which is used to offset the costs of various benefit and retirement plans. The Company’s investment in bank-owned life insurance does not exceed the regulatory limitation of 25% of Tier 1 capital plus the allowance for loan and lease losses. The aggregate cash surrender value of all policies owned by the Company amounted to $34.6 million and $33.7 million at December 31, 2018 and 2017 , respectively. During 2017, the Company purchased additional policies with aggregate cash surrender value of $11.8 million . Income earned on these life insurance policies aggregated $907,000 , $613,000 and $570,000 for the years ended December 31, 2018 , 2017 and 2016 , respectively. There were no gains recognized on death benefit proceeds received during the years ended December 31, 2018 , 2017 and 2016 .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure	OTHER COMMITMENTS AND CONTINGENCIES In the normal course of business, there are outstanding commitments and contingencies not reflected in the accompanying consolidated financial statements. The Company is a party to financial instruments with off-balance sheet risk to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit and involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized on the balance sheets. The contractual amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments. Loan Commitments and Letters of Credit The contractual amounts of commitments to extend credit represent the amount of potential loss should the contract be fully drawn upon, the customer defaults and the value of any existing collateral be determined as worthless. 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 at December 31, 2018 and 2017 were as follows: December 31, 2018 2017 (In Thousands) Commitments to extend credit: Commitments to originate loans $ 23,441 $ 60,360 Undisbursed construction loans 42,848 9,027 Undisbursed home equity lines of credit 59,314 56,044 Undisbursed commercial lines of credit 67,576 50,054 Overdraft protection lines 1,249 1,306 Standby letters of credit 338 134 Total commitments $ 194,766 $ 176,925 Commitments to originate loans at December 31, 2018 and 2017 included fixed rate loan commitments of $13.0 million and $34.1 million , respectively, at interest rates ranging from 3.00% to 6.88% and 2.88% to 6.00% , 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. 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 varies but may include residential and commercial property, accounts receivable, inventory, property, plant and equipment, deposits and securities. Undisbursed commitments under construction and home equity or commercial lines of credit are commitments for future extensions of credit to existing customers. Total undisbursed amounts on lines of credit may expire without being fully drawn upon and therefore, do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Letters of credit are primarily issued to support public or private borrowing arrangements. Essentially all letters of credit issued have expiration dates within one year. Operating Lease Commitments The Company leases certain of its branch offices and equipment under operating lease agreements that expire at various dates through 2039. At December 31, 2018 , future minimum rental commitments pursuant to the terms of noncancelable lease agreements, by year and in the aggregate, are as follows (in thousands ): 2019 $ 1,382 2020 1,264 2021 1,115 2022 972 2023 970 Thereafter 6,315 Total $ 12,018 Certain leases contain options to extend for periods of 5 to 50 years. The cost of such extensions is not included in the above amounts. Rental expense charged to operations for cancelable and noncancelable operating leases was $1.4 million for the year ended December 31, 2018 and $1.5 million for each of the years ended December 31, 2017 and 2016 . Rental Income Under Subleases The Company is subleasing excess office space under cancelable and noncancelable operating leases that expire at various dates through 2025. At December 31, 2018 , future minimum lease payments receivable for the noncancelable lease agreement is as follows (in thousands) : 2019 $ 115 2020 115 2021 115 2022 115 2023 115 Thereafter 201 Total $ 776 Rental income under the cancelable and noncancelable lease agreement was $130,000 , $287,000 and $268,000 for the years ended December 31, 2018 , 2017 and 2016 , respectively. Investment Commitments The Bank is a limited partner in three SBICs and committed to contribute capital of $3.0 million to the limited partnerships. The Bank recognized no write-downs during the years ended December 31, 2018 , 2017 and 2016. The SBICs, with a combined net book value of $1.4 million and $1.8 million at December 31, 2018 and 2017 , respectively, net of impairment charges and distributions, are included in other assets. At December 31, 2018 , the Bank’s remaining off-balance sheet commitment for capital investment in the SBICs was $787,000 . Change in Control Agreements The Company has entered into change in control agreements with certain officers that provide for certain benefits for a specified period of time under certain conditions. Under the terms of the agreements, these payments could occur in the event of a change in control of the Company, as defined, along with other specific conditions. Depending on the officer, the severance payment under these agreements is equal to either one, two or three times the individual's annual salary in the event of a change in control. Legal Matters Various legal claims arise from time to time in the normal course of business. Management believes the resolution of these matters will not have a material effect on the Company’s financial condition or results of operations.

Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	RELATED PARTY TRANSACTIONS Loans Receivable In the normal course of business, the Bank grants loans to related parties. Related parties include directors and certain officers of the Company and its subsidiaries and their immediate family members and respective affiliates in which they have a controlling interest. These loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with customers, and did not involve more than the normal risk of collectibility, favored treatment or terms or present other unfavorable features. At December 31, 2018 and 2017 , all related party loans were performing in accordance with their terms. Changes in loans outstanding to such related parties during the years ended December 31, 2018 and 2017 are as follows: Years Ended December 31, 2018 2017 (In Thousands) Balance at beginning of year $ 1,335 $ 1,543 Additions 552 178 Repayments (449 ) (386 ) Balance at end of year $ 1,438 $ 1,335 Deposits Deposit accounts of directors, certain officers and other related parties aggregated $1.2 million at both December 31, 2018 and 2017 .

REGULATORY CAPITAL

REGULATORY CAPITAL	12 Months Ended
	Dec. 31, 2018
Banking and Thrift [Abstract]
Regulatory Capital	REGULATORY CAPITAL The Bank is subject to regulatory capital requirements promulgated by federal bank regulatory agencies. Failure by the Bank to meet minimum capital requirements could result in certain mandatory and discretionary actions by regulators that could have a material adverse effect on our consolidated financial statements. Under Basel III capital requirements, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation require the Bank to maintain certain minimum capital amounts and ratios. Federal bank regulators require the Bank to maintain minimum ratios of core capital to adjusted average assets, common equity tier 1 capital to risk-weighted assets, tier 1 capital to risk-weighted assets and total risk-based capital to risk-weighted assets. At December 31, 2018 and 2017 , the Bank met all the capital adequacy requirements to which they were subject and were “well capitalized” under the regulatory requirements. Management believes no conditions or events have occurred since December 31, 2018 that would materially adversely change the Bank's capital classifications. Effective January 1, 2016, Basel III implemented a requirement for all banking organizations to maintain a capital conservation buffer exclusively composed 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, stock repurchases and discretionary bonus payments to executive officers. The capital conservation buffer increases the three risk-based capital ratios and will be phased in over a multi-year schedule with full compliance in 2019. Management believes the Bank's capital levels will remain characterized as "well-capitalized" under the new rules. As a result of the recently enacted Economic Growth, Regulatory Relief and Consumer Protection Act, the Federal Reserve Board amended its Small Bank Holding Company Policy Statement to provide that bank holding companies and savings and loan companies with consolidated assets of less than $3 billion that (i) are not engaged in significant non-banking activities, (ii) do not conduct significant off-balance sheet activities and (iii) do not have a material amount of SEC-registered debt or equity securities, other than trust preferred securities, that contribute to an organization’s complexity, will no longer be subject to regulatory capital requirements, effective no later than November 2018. In addition, as a result of the legislation, the federal banking agencies are required to develop a “Community Bank Leverage Ratio” (the ratio of a bank’s tangible equity capital to average total consolidated assets) for financial institutions with assets of less than $10 billion. A “qualifying community bank” that exceeds this ratio will be deemed to be in compliance with all other capital and leverage requirements, including the capital requirements to be considered “well capitalized” under Prompt Corrective Action statutes. The federal banking agencies may consider a financial institution’s risk profile when evaluating whether it qualifies as a community bank for purposes of the capital ratio requirement. The federal banking agencies must set the minimum capital for the new Community Bank Leverage Ratio at not less than 8% and not more than 10%. A financial institution can elect to be subject to this new definition. The Bank's regulatory capital amounts and ratios at December 31, 2018 and 2017 , compared to the FDIC's requirements for classification as a well-capitalized institution and for minimum capital adequacy, were as follows: December 31, 2018 Actual Minimum Capital Requirement Minimum To Be Well Capitalized Under Prompt Corrective Action Provisions Amount Ratio Amount Ratio Amount Ratio (Dollars in Thousands) Common Equity Tier 1 Capital: $ 154,215 12.88 % $ 53,865 4.50 % $ 77,805 6.50 % Tier 1 Capital to Risk Weighted Assets: 154,215 12.88 71,820 6.00 95,760 8.00 Total Capital to Risk Weighted Assets: 169,182 14.13 95,760 8.00 119,700 10.00 Tier 1 Capital to Average Assets: 154,215 9.58 64,374 4.00 80,468 5.00 December 31, 2017 Actual Minimum Capital Requirement Minimum To Be Well Capitalized Under Prompt Corrective Action Provisions Amount Ratio Amount Ratio Amount Ratio (Dollars in Thousands) Common Equity Tier 1 Capital: $ 146,509 13.81 % $ 47,740 4.50 % $ 68,958 6.50 % Tier 1 Capital to Risk Weighted Assets: 146,509 13.81 63,653 6.00 84,871 8.00 Total Capital to Risk Weighted Assets: 159,303 15.02 84,871 8.00 106,089 10.00 Tier 1 Capital to Average Assets: 146,509 9.40 62,348 4.00 77,934 5.00 Reconciliations of the Bank’s total capital to regulatory capital are as follows: December 31, 2018 2017 (In Thousands) Total capital per financial statements $ 167,894 $ 160,495 Adjustments to tier 1 capital: Accumulated losses on available for sale securities 2,088 1,397 Intangible assets (15,767 ) (15,383 ) Total tier 1 capital 154,215 146,509 Adjustments to total capital: Allowance for loan and credit losses 14,967 12,794 Total capital per regulatory reporting $ 169,182 $ 159,303

FAIR VALUE OF ASSETS AND LIABIL

FAIR VALUE OF ASSETS AND LIABILITIES	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Disclosures	FAIR VALUE OF ASSETS AND LIABILITIES Determination of Fair Value The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The fair value of assets and liabilities is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various assets and liabilities. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the assets and liabilities. The following methods and assumptions were used by the Company in estimating fair value disclosures of its financial instruments: ◦ Cash and cash equivalents. The carrying amounts of cash and cash equivalents approximate the fair values based on the short-term nature of the assets. ◦ Securities available for sale. Included in the available for sale category are debt securities. The securities measured at fair value in Level 1 are based on quoted market prices in an active exchange market. Securities measured at fair value in Level 2 are based on pricing models that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes, credit spreads and new issue data. The Company utilizes a nationally-recognized third-party pricing service to estimate fair value measurements for the majority of its portfolio. The pricing service evaluates each asset class based on relevant market information considering observable data, but these prices do not represent binding quotes. The fair value prices on all investments are reviewed for reasonableness by management. Securities measured at fair value in Level 3 include one collateralized debt obligation that was backed by a trust preferred security issued by banks and insurance companies. Management determined that an orderly and active market for this security and similar securities did not exist based on a significant reduction in trading volume and widening spreads relative to historical levels. The Company estimates future cash flows discounted using a rate management believes is representative of current market conditions. Factors in determining the discount rate include the current level of deferrals and/or defaults, changes in credit rating and the financial condition of the debtors within the underlying securities, broker quotes for securities with similar structure and credit risk, interest rate movements and pricing for new issuances. ◦ Federal Home Loan Bank stock. The carrying value of FHLB stock approximates fair value based on the redemption provisions of the FHLB. ◦ Federal Reserve Bank stock. The carrying value of FRB stock approximates fair value based on the redemption provisions of the FRB. ◦ Loans held for sale. The fair value of loans held for sale is estimated using quoted market prices. ◦ Loans receivable. For variable rate loans that reprice frequently and have no significant change in credit risk, fair values are based on carrying values. The fair value of fixed-rate loans are estimated by discounting the future cash flows using the rates at the end of the period in which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Fair values for nonperforming loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable. ◦ Accrued interest receivable. The carrying amount of accrued interest approximates fair value. ◦ Deposits. The fair value of demand deposits, negotiable orders of withdrawal, regular savings, certain money market deposits and mortgagors’ and investors’ escrow accounts is the amount payable on demand at the reporting date. The fair value of certificates of deposit and other time deposits is estimated using a discounted cash flow calculation that applies interest rates currently being offered for deposits of similar remaining maturities to a schedule of aggregated expected maturities on such deposits. ◦ Federal Home Loan Bank advances. The fair value of the advances is estimated using a discounted cash flow calculation that applies current FHLB interest rates for advances of similar maturity to a schedule of maturities of such advances. ◦ Junior subordinated debt owed to unconsolidated trust. Rates currently available for debt with similar terms and remaining maturities are used to estimate fair value of existing debt. ◦ Interest rate swap agreement. The fair value of the Company’s interest rate swap is obtained from a third-party pricing service and are determined using a discounted cash flow analysis on the expected cash flows of the derivative. The pricing analysis is based on observable inputs for the contractual term of the derivative, including the period to maturity, credit component and interest rate curves. ◦ Forward loan sale commitments and derivative loan commitments. Forward loan sale commitments and derivative loan commitments are based on the fair values of the underlying mortgage loans, including the servicing rights for derivative loan commitments, and the probability of such commitments being exercised. Significant management judgment and estimation is required in determining these fair value measurements. ◦ Off-balance sheet instruments. Fair values for off-balance sheet lending commitments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties' credit standings. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following tables present assets and liabilities measured at fair value on a recurring basis as of December 31, 2018 and 2017 . The Company had no significant transfers into or out of Levels 1, 2 or 3 during the years ended December 31, 2018 and 2017 .

These adjustments to fair value usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets. The following table summarizes the fair value hierarchy used to determine each adjustment and the carrying value of the related individual assets at December 31, 2018 and 2017 . There were no liabilities measured at fair value on a nonrecurring basis at December 31, 2018 and 2017 .

The fair value of collateral used by the Company represents the amount expected to be received from the sale of the property, net of selling costs, as determined by an independent, licensed or certified appraiser using observable market data. This data includes information such as selling price of similar properties, expected future cash flows or earnings of the subject property based on current market expectations and relevant legal, physical and economic factors. The appraised values of collateral are adjusted as necessary by management based on observable inputs for specific properties. Losses applicable to write-downs of impaired loans are based on the appraised market value of the underlying collateral, assuming foreclosure of these loans is imminent, and are recorded through the provision for loan losses. The amount of other real estate owned represents the carrying value of the collateral based on the appraised value of the underlying collateral less estimated selling costs. The loss on foreclosed assets represents adjustments in the valuation recorded during the time period indicated and not for losses incurred on sales. The Company evaluates its goodwill for impairment in accordance with applicable accounting guidance. Based on this evaluation, no goodwill impairment was recorded during the years ended December 31, 2018 , 2017 and 2016 . Summary of Fair Values of Financial Instruments The estimated fair values, and related carrying or notional amounts, of the Company’s financial instruments are presented in the following table. Certain financial instruments and all nonfinancial instruments are exempt from disclosure requirements. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company. Management uses its best judgment in estimating the fair value of the Company's financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates presented herein are not necessarily indicative of the amounts the Company could have realized in a sales transaction at December 31, 2018 or 2017 . The estimated fair value amounts for 2018 and 2017 have been measured as of their respective year-ends, and have not been re-evaluated or updated for purposes of these consolidated financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each year-end. The information presented should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only required for a limited portion of the Company's assets. Due to the wide range of valuation techniques and the degree of subjectivity used in making the estimate, comparisons between the Company's disclosures and those of other banks may not be meaningful. As of December 31, 2018 and 2017 , the recorded carrying amounts and estimated fair values of the Company's financial instruments are as follows: December 31, 2018 Carrying Amount Level 1 Level 2 Level 3 Total Financial Assets: (In Thousands) Cash and cash equivalents $ 87,929 $ 87,929 $ — $ — $ 87,929 Available for sale securities 143,822 18,391 124,605 826 143,822 Loans held for sale 1,915 — — 1,950 1,950 Loans receivable, net 1,312,565 — — 1,285,733 1,285,733 Federal Home Loan Bank stock 9,035 — — 9,035 9,035 Federal Reserve Bank stock 3,638 — — 3,638 3,638 Accrued interest receivable 4,921 — — 4,921 4,921 Financial Liabilities: Deposits 1,288,031 — — 1,288,238 1,288,238 Mortgagors' and investors' escrow accounts 4,701 — — 4,701 4,701 Federal Home Loan Bank advances 151,836 — 149,838 — 149,838 Junior subordinated debt owed to unconsolidated trust 8,248 — 6,613 — 6,613 On-balance Sheet Derivative Financial Instruments: Assets: Derivative loan commitments 23 — — 23 23 Forward loan sale commitments 66 — — 66 66 Interest rate swap agreements 1,533 — 1,533 — 1,533 Liabilities: Forward loan sale commitments 1 — — 1 1 Interest rate swap agreements 1,533 — 1,533 — 1,533 December 31, 2017 Carrying Amount Level 1 Level 2 Level 3 Total Financial Assets: (In Thousands) Cash and cash equivalents $ 83,486 $ 83,486 $ — $ — $ 83,486 Available for sale securities 154,053 19,435 133,494 1,124 154,053 Loans held for sale 835 — — 847 847 Loans receivable, net 1,237,174 — — 1,229,696 1,229,696 Federal Home Loan Bank stock 9,856 — — 9,856 9,856 Federal Reserve Bank stock 3,636 — — 3,636 3,636 Accrued interest receivable 4,784 — — 4,784 4,784 Financial Liabilities: Deposits 1,208,047 — — 1,209,458 1,209,458 Mortgagors' and investors' escrow accounts 4,418 — — 4,418 4,418 Federal Home Loan Bank advances 170,094 — 163,568 — 163,568 Junior subordinated debt owed to unconsolidated trust 8,248 — 6,231 — 6,231 On-balance Sheet Derivative Financial Instruments: Assets: Derivative loan commitments 27 — — 27 27 Forward loan sale commitments 16 — — 16 16

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Derivative Instruments Not Designated As Hedging Instruments Certain derivative instruments do not meet the requirements to be accounted for as hedging instruments. These undesignated derivative instruments are recognized on the consolidated balance sheets at fair value, with changes in fair value recorded in other noninterest income. Derivative Loan Commitments - Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. The Company enters into commitments to fund residential mortgage loans at specified times in the future, with the intention that these loans will subsequently be sold in the secondary market. A mortgage loan commitment binds the Company to lend funds to a potential borrower at a specified interest rate and within a specified period of time, generally up to 60 days after inception of the rate lock. Outstanding derivative loan commitments expose the Company to the risk that the price of the loans arising from exercise of the loan commitment might decline from inception of the rate lock to funding of the loan due to increases in mortgage interest rates. If interest rates increase, the value of these loan commitments decrease. Conversely, if interest rates decrease, the value of these loan commitments increase. Forward Loan Sale Commitments - To protect against the price risk inherent in the exercise of derivative loan commitments resulting from potential decreases in the value of loans, the Company utilizes both “mandatory delivery” and "best efforts" forward loan sale commitments. With a “mandatory delivery” contract, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. If the Company fails to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, it is obligated to pay a “pair-off” fee, based on then-current market prices, to the investor to compensate the investor for the shortfall. With a "best efforts" contract, the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor if the loan to the underlying borrower closes. Generally, the price the investor will pay the seller for an individual loan is specified prior to the loan being funded (e.g., on the same day the lender commits to lend funds to a potential borrower). The Company expects these forward loan sale commitments will experience changes in fair value opposite to the change in fair value of derivative loan commitments. Interest Rate Swap Agreements - 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." As of December 31, 2018 , based on the current position of the Company's interest rate swap agreements, the Company paid $1.4 million into a collateral account with the correspondent bank to collateralize its net liability position. The Company and correspondent bank have an agreement to secure any outstanding payable in excess of $100,000 . The Company's agreements with its derivative counterparties contain the following provisions related to contingent credit risk: • if the Company defaults on any of its indebtedness, including a 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 position, 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, 2018 . The Company has established a derivative 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 in other assets and other liabilities on the consolidated balance sheets at fair value.

Restrictions on Dividends, Loans and Advances [Abstract]
Restrictions on Dividends, Loans and Advances	RESTRICTIONS ON DIVIDENDS, LOANS AND ADVANCES Federal and state regulations place certain restrictions on dividends paid and loans or advances made by the Bank to the Company. The total amount of dividends which may be declared in a given calendar year without regulatory approval is generally limited to the net income of the Bank for that year plus retained net income for the preceding two years. At December 31, 2018 and 2017 , the Bank’s retained earnings available for payment of dividends was $18.4 million and $15.2 million , respectively. Accordingly, $149.5 million and $145.3 million of the Company’s equity in the net assets of the Bank were restricted at December 31, 2018 and 2017 , respectively. In addition, the Company is further restricted, under its junior subordinated debt obligation, from paying dividends to its shareholders if the Company has deferred interest payments or has otherwise defaulted on its junior subordinated debt obligation. Under federal regulation, the Bank is also limited to the amount it may loan to the Company, unless such loans are collateralized by specific obligations. Loans or advances to the Company by the Bank are limited to 10% of the Bank’s capital stock and surplus on a secured basis. In addition, dividends paid by the Bank to the Company would be prohibited if the effect thereof, would cause the Bank’s capital to be reduced below applicable minimum capital requirements.

Common Stock Repurchase Program [Abstract]
Common Stock	COMMON STOCK REPURCHASE PROGRAM The Company repurchases stock primarily to create economic value for its shareholders and to provide additional liquidity to the stock. Shares are purchased as part of a board approved plan or withheld on behalf of plan participants to satisfy tax withholding obligations related to the vesting of restricted shares. Shares repurchased are retired and reflected as a reduction in shareholders’ equity. On May 9, 2018, the Company announced that the Board of Directors had approved a stock repurchase program authorizing the Company to repurchase up to 5% , or 612,122 shares, of its common stock from time to time, depending on market conditions. The repurchase program will continue until it is completed or terminated by the Company's Board of Directors. For the year ended December 31, 2018, the Company repurchased 215,000 shares of its equity securities at a cost of $3.2 million . As of December 31, 2018, 397,122 shares remain available for purchase under the program. No repurchase plans were approved or executed in 2017 .

NATURE OF BUSINESS AND SUMMAR_2

NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2018
NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company, its wholly-owned subsidiary, the Bank, and the Bank’s wholly-owned subsidiaries, SI Mortgage Company and SI Realty Company, Inc. All significant intercompany accounts and transactions have been eliminated.
Basis of Accounting, Policy [Policy Text Block]	Basis of Financial Statement Presentation The consolidated financial statements have been prepared in accordance with GAAP and general practices within the banking industry. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities, as of the date of the balance sheets and reported amounts of revenues and expenses for the years presented. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, deferred income taxes and the impairment of long-lived assets.
Reclassification, Policy [Policy Text Block]	Reclassifications Certain amounts in the Company’s prior year consolidated financial statements were reclassified to conform to the current year presentation. Such reclassifications had no effect on net income.
Significant Group Concentrations of Credit Risk, Policy [Policy Text Block]	Significant Group Concentrations of Credit Risk A majority of the Company’s activities are with customers located within eastern Connecticut and Rhode Island. The Company does not have any significant concentrations in any one industry or customer. See Notes 3 and 4 for details relating to the Company’s investment and lending activities.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents and Statements of Cash Flows Cash and due from banks, federal funds sold and short-term investments with maturities at the date of purchase of less than 90 days are recognized as cash equivalents in the statements of cash flows. Federal funds sold generally mature in one day. For purposes of reporting cash flows, the Company considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. Cash flows from loans and deposits are reported on a net basis. The Company maintains amounts due from banks and federal funds sold that, at times, may exceed federally insured limits. The Company has not experienced any losses from such concentrations.
Fair Value Hierarchy, Policy [Policy Text Block]	Fair Value Hierarchy The Company groups its assets and liabilities in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1 – Valuation is based on quoted prices in active markets for identical assets or liabilities. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 – Valuation is based on 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 for substantially the full term of the assets or liabilities. Level 3 – Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include assets or liabilities whose value is determined using unobservable inputs to pricing models, discounted cash flow methodologies, or similar techniques, as well as assets or liabilities for which the determination of fair value requires significant management judgment or estimation. Transfers between levels are recognized at the end of a reporting period, if applicable.
Securities, Policy [Policy Text Block]	Securities Management determines the appropriate classification of securities at the date individual securities are acquired, and the appropriateness of such classification is reassessed at each reporting date. Debt securities that management has the positive intent and ability to hold to maturity are classified as “held to maturity” and recorded at amortized cost. Securities that are held principally for trading in the near term are classified as “trading securities.” Trading securities are carried at fair value, with unrealized gains and losses recognized in earnings. Interest and dividends are included in net interest income. Securities not classified as held to maturity or trading, including equity securities with readily determinable fair values, are classified as “available for sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive loss, net of taxes. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. At each reporting period, the Company evaluates securities with a decline in fair value below the amortized cost of the investment to determine whether or not the impairment is deemed to be other than temporary. The evaluation is based upon factors such as the creditworthiness of the issuers/guarantors, the underlying collateral, if applicable, and the continuing performance of the securities. Management also evaluates other facts and circumstances that may be indicative of an other-than-temporary impairment ("OTTI") condition, such as the type of security, length of time and extent to which the fair value has been less than cost and near-term prospects of the issuers. OTTI is required to be recognized if (1) the Company intends to sell the security; (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) for debt securities, the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. For impaired debt securities that the Company intends to sell, or more likely than not will be required to sell, the full amount of the depreciation is recognized as OTTI through earnings. For all other impaired debt securities, credit-related OTTI is recognized through earnings and noncredit-related OTTI is recognized in other comprehensive loss, net of applicable taxes. See Notes 3 and 15 for more details.
Federal Home Loan Bank Stock, Policy [Policy Text Block]	Federal Home Loan Bank Stock The Bank, as a member of the FHLB, is required to maintain an investment in the capital stock of the FHLB. The stock has no quoted market value and is carried at cost. At its discretion, the FHLB may declare dividends on its stock. The stock is redeemable at par by the FHLB and the Company’s ability to redeem the shares owned is dependent on the redemption practices of the FHLB. The Company reviews its investment in FHLB stock for impairment based on the ultimate recoverability of the cost basis in the FHLB stock. No impairment charges were recognized for the years ended December 31, 2018 , 2017 or 2016 .
Federal Reserve Bank stock [Policy Text Block]	Federal Reserve Bank Stock The Bank, as a member of the FRB, is required to maintain an investment in capital stock of the FRB. The stock has no quoted market value and is carried at cost. The Company reviews its investment in FRB stock for impairment based on the ultimate recoverability of the cost basis in FRB stock. No impairment charges were recognized for the years ended December 31, 2018 , 2017 or 2016 .
Loans Held-for-sale, Policy [Policy Text Block]	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 noninterest 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 and reported within mortgage banking activities on the accompanying consolidated statements of income.
Loans Receivable, Policy [Policy Text Block]	Loans Receivable Loans receivable are stated at current unpaid principal balances, net of the allowance for loan losses and deferred loan origination fees and costs. Management has the ability and intent to hold its loans receivable for the foreseeable future or until maturity or pay-off. A loan is impaired when, based on current information and events, it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the 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. Impairment is measured on a loan by loan basis for residential and commercial mortgage loans and commercial business loans by either the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not typically identify individual consumer loans for impairment disclosures unless such loans are subject to a troubled debt restructuring (“TDR”) agreement. The Company periodically may agree to modify the contractual terms of loans. When a loan is modified and concessions have been made to the original contractual terms due to the borrower's financial condition that would not otherwise be considered for a borrower with similar risk characteristics such as reductions of interest rates, deferral of interest or principal payments or maturity extensions, the modification is considered a TDR. Modified terms are dependent upon the financial position and needs of the individual borrower. If the modification agreement is violated, the loan is handled by the Company’s Collections Department for resolution, which may result in foreclosure.
Allowance for Loan Losses, Policy [Policy Text Block]	Allowance for Loan Losses The allowance for loan losses, a material estimate which could change significantly in the near-term, is established through a provision for loan losses charged to earnings to account for losses that are inherent in the loan portfolio and estimated to occur, and is maintained at a level management considers adequate to absorb losses in the loan portfolio. Loan losses are charged against the allowance for loan losses when management believes the uncollectibility of the principal loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance for loan losses when received. Management's judgment in determining the adequacy of the allowance is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance for loan losses is evaluated on a monthly basis by management and is based on the evaluation of the known and inherent risk characteristics and size and composition of the loan portfolio, the assessment of current economic and real estate market conditions, adverse situations that may affect a borrower’s ability to repay, estimated value of any underlying collateral, historical loan loss experience, the amount and trends of nonperforming loans, delinquencies, classified assets and loan charge-offs and evaluations of loans and other relevant factors. The allowance for loan losses consists of the following key elements: ◦ Specific allowance for identified impaired loans . For loans identified as impaired, an allowance is established when the present value of expected cash flows (or observable market price of the loan or fair value of the collateral if the loan is collateral dependent) of the impaired loan is lower than the carrying value of that loan. In the determination of the specific allowance for loan losses, management may obtain independent appraisals for significant properties, when necessary. ◦ General valuation allowance. The general component represents a valuation allowance on the remainder of the loan portfolio, after excluding impaired loans. For this portion of the allowance, loans are segregated by category and assigned an allowance percentage based on historical loan loss experience adjusted for qualitative factors stratified by the following loan segments: residential one- to four-family, multi-family and commercial real estate, construction, commercial business and consumer. Management uses a rolling average of historical losses based on the time frame appropriate to capture relevant loss data for each loan segment. This historical loss factor is adjusted for the following qualitative factors: changes in lending policies and procedures, including changes in underwriting standards and collections, charge-off and recovery practices; changes in national, regional and local economic and business conditions and developments that affect the collectibility of the portfolio, including the condition of various market segments; changes in the size and composition of the loan portfolio and in the terms of the loans; changes in the experience, ability and depth of lending and underwriting management and other relevant staff; changes in the volume and severity of past due loans, the volume of nonaccrual loans and the volume and severity of adversely classified or graded loans; changes in the quality of the loan review system; changes in the underlying collateral for collateral-dependent loans; the existence and effect of any concentrations of credit and changes in the level of such concentrations; the effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the portfolio. The qualitative factors are determined based on the following various risk characteristics for each loan segment. Risk characteristics relevant to each portfolio segment are as follows: Residential – One- to Four-Family – The Bank primarily originates conventional loans with loan-to-value ratios less than 95% and generally originates loans with loan-to-value ratios in excess of 80% only when secured by first liens on owner-occupied one- to four-family residences. Loans with loan-to-value ratios in excess of 80% generally require private mortgage insurance or additional collateral. All loans in this segment are collateralized by owner-occupied residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality of this segment. Multi-family and Commercial – Loans in this segment are originated to acquire, develop, improve or refinance multi-family and commercial real estate where the property is the primary collateral securing the loan, and the income generated from the property is the primary repayment source. The underlying cash flows generated by the properties can be impacted by the economy as evidenced by increased vacancy rates. Payments on loans secured by income-producing properties often depend on the successful operation and management of the properties. Management continually monitors the cash flows of these loans. Construction – This segment includes loans to individuals, and to a lesser extent builders, to finance the construction of residential dwellings. The Bank also originates construction loans for commercial development projects. Upon the completion of construction, the loan generally converts to a permanent mortgage loan. Credit risk is affected by cost overruns, whether estimates of the sale price of the property are correct, the time it takes to sell at an adequate price and market conditions. Commercial Business – 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 reduced viability of the industry in which the customer operates will have a negative impact on the credit quality in this segment. The Bank provides loans to investors in the time share industry, which are secured by consumer receivables, and provides loans for capital improvements to condominium associations, which are secured by the assigned rights to levy special assessments to condominium owners. Additionally, the Bank purchases loans primarily out of our market area from a company specializing in medical loan originations, which are secured by medical equipment. Consumer – Loans in this segment primarily include home equity lines of credit (representing both first and second liens) and, to a lesser extent, loans secured by marketable securities, passbook or certificate accounts, motorcycles, automobiles and recreational vehicles, as well as unsecured loans. Consumer loan collections depend on the borrower’s continuing financial stability, and therefore, are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy. In computing the allowance for loan losses, we do not assign a general valuation allowance to the Small Business Administration ("SBA") and United States Department of Agriculture ("USDA") loans that we purchase as such loans are fully guaranteed. These loans are included in commercial business loans. The majority of the Company's loans are collateralized by real estate located in eastern Connecticut and Rhode Island. To a lesser extent, certain commercial real estate loans are secured by collateral located outside of our primary market area, with concentrations in Massachusetts and New Hampshire. Accordingly, the collateral value of a substantial portion of the Company's loan portfolio and real estate acquired through foreclosure is susceptible to changes in local market conditions. Although management believes it uses the best information available to establish the allowance for loan losses, future adjustments to the allowance for loan losses may be necessary and the Company’s results of operations could be adversely affected if circumstances differ substantially from the assumptions used in making the determinations. Furthermore, while management believes it has established the allowance for loan losses in conformity with GAAP, our regulators, in reviewing the loan portfolio, may request us to increase our allowance for loan losses based on judgments different from ours. In addition, because future events affecting borrowers and collateral cannot be predicted with certainty, the existing allowance for loan losses may not be adequate or increases may be necessary should the quality of any loans deteriorate as a result of the factors discussed above. Any material increase in the allowance for loan losses would adversely affect the Company’s financial condition and results of operations.
Deteriorated Loans Transferred in, Policy [Policy Text Block]	Loans Acquired with Deteriorating Credit Quality Loans acquired in a transfer, including business combinations, where there is evidence of credit deterioration since origination and it is probable at the date of acquisition the Company will not collect all contractually required principal and interest payments, are accounted for under accounting guidance for purchased credit-impaired loans. Applicable guidance provides that the excess of the cash flows initially expected to be collected over the fair value of the loans at the acquisition date (i.e., the accretable yield) is accreted into interest income over the estimated remaining life of the loans, provided that the timing and amount of future cash flows is reasonably estimable. Such loans are considered to be accruing because their interest income relates to the accretable yield and not to contractual interest payments. The difference between the contractually required payments and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference. Subsequent to acquisition, probable decreases in expected cash flows are recognized through a provision for loan losses, resulting in an increase to the allowance for loan losses. If the Company has probable and significant increases in cash flows expected to be collected, the Company will first reverse any previously established allowance for loan losses and then increase interest income as a prospective yield adjustment.
Interest and Fees on Loans, Policy [Policy Text Block]	Interest and Fees on Loans Interest on loans is accrued and included in net interest income based on contractual rates applied to principal amounts outstanding. Accrual of interest is discontinued when loan payments are 90 days or more past due, based on contractual terms, or when, in the judgment of management, collectibility of the loan or loan interest becomes uncertain. Subsequent recognition of income occurs only to the extent payment is received subject to management's assessment of the collectibility of the remaining interest and principal. A nonaccrual loan is restored to accrual status when it is no longer delinquent and collectibility of interest and principal is no longer in doubt and the borrower has made regular payments in accordance with the terms of the loan over a period of at least six months. Interest collected on nonaccrual loans is recognized only to the extent cash payments are received, and may be recorded as a reduction to principal if the collectibility of the principal balance of the loan is unlikely. Loan origination fees, direct loan origination costs and loan purchase premiums are deferred and the net amount is recognized as an adjustment of the related loan's yield utilizing the interest method over the contractual life of the loan. In addition, discounts related to fair value adjustments for loans receivable acquired in a business combination or asset purchase are accreted into earnings over the contractual term as an adjustment of the related loan's yield. The Company periodically evaluates the cash flows expected to be collected for loans acquired with deteriorated credit quality. Changes in the expected cash flows compared to the expected cash flows as of the date of acquisition may impact the accretable yield or result in a charge to the provision for loan losses to the extent of a shortfall.
Derivative Financial Instruments, Policy [Policy Text Block]	Derivative Instruments Not Designated As Hedging Instruments Certain derivative instruments do not meet the requirements to be accounted for as hedging instruments. These undesignated derivative instruments are recognized on the consolidated balance sheets at fair value, with changes in fair value recorded in other noninterest income. Interest Rate Swap Agreements - 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 to manage the Company's exposure to interest rate movements but do not meet the strict hedge accounting as defined by the Financial Accounting Standards Board ("FASB") (Topic 815) per "Derivatives and Hedging." The interest rate swap agreement enables the customer to synthetically fix the interest rate on a variable rate loan. The customer pays a variable rate and enters 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 agreements with our customers are cross-collateralized by the loan collateral and do not have any embedded interest rate caps or floors. For every variable rate loan and fixed rate swap agreement entered into with a commercial customer, the Company simultaneously enters into an offsetting fixed rate swap agreement with a correspondent bank, agreeing to pay a fixed payment and receive a variable interest rate swap. The Company is party to master netting agreements with its correspondent bank; 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. Derivative Loan Commitments - Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. Loan commitments that are derivatives are recognized at fair value on the consolidated balance sheets in other assets and other liabilities with changes in their fair values recorded in mortgage banking within noninterest income. Forward Loan Sale Commitments - To protect against the price risk inherent in the exercise of derivative loan commitments, the Company utilizes both “mandatory delivery” and "best efforts" forward loan sale commitments. Mandatory delivery contracts and best efforts contracts are accounted for as derivative instruments. Mandatory and best efforts delivery forward loan sale commitments are recognized at fair value on the consolidated balance sheets in other assets and other liabilities with changes in their fair values recorded in mortgage banking within noninterest income.
Transfer of Financial Assets, Policy [Policy Text Block]	Transfers of Financial Assets Transfers of financial assets 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 no condition both constrains the transferee from taking advantage of that right and provides more than a trivial benefit for the transferor and (3) the transferor does not maintain effective control over the transferred assets through either (a) an agreement that both entitles and obligates the transferor to repurchase or redeem the assets before maturity or (b) the ability to unilaterally cause the holder to return specific 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.
Other Real Estate Owned, Policy [Policy Text Block]	Other Real Estate Owned Other real estate owned consists of properties acquired through, or in lieu of, loan foreclosure or other proceedings and is initially recorded at fair value at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, the properties are held for sale and are carried at the lower of carrying amount or fair value less estimated costs of disposal. Any write-down to fair value at the time of acquisition is charged to the allowance for loan losses. 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. Gains or losses are included in noninterest expenses upon disposal.
Property, Plant and Equipment, Policy [Policy Text Block]	Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is charged to operations using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the estimated economic lives of the improvements or the expected lease terms. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured. The estimated useful lives of the assets are as follows: Classification Estimated Useful Lives Buildings 5 to 40 years Furniture and equipment 3 to 10 years Leasehold improvements 5 to 20 years Gains and losses on dispositions are recognized upon realization. Maintenance and repairs are expensed as incurred and improvements are capitalized.
Bank-owned Life Insurance, Policy [Policy Text Block]	Bank-owned Life Insurance Bank-owned life insurance policies are presented on the consolidated balance sheets at cash surrender value. Changes in cash surrender value, as well as gains on the surrender of policies, are reflected in noninterest income in the consolidated statements of income and are not subject to income taxes. See Note 11 for additional discussion.
Mortgage Servicing Assets, Policy [Policy Text Block]	Servicing The Company services mortgage loans for others. Mortgage servicing assets are recognized as separate assets at fair value when rights are acquired through purchase or retained through the sale of loans. Fair value is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Capitalized servicing rights are reported in other assets and are amortized into mortgage banking income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to the amortized cost. Impairment is determined by stratifying rights by predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual stratum, to the extent that the fair value is less than the capitalized amount for the stratum. Changes in the valuation allowance are reported in loan servicing fee income. Servicing fee income is recorded for fees earned for servicing loans, which is included in mortgage banking income. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned.
Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block]	Impairment of Long-lived Assets Long-lived assets, including premises and equipment and certain identifiable intangible assets that are held and used by the Company, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If impairment is indicated by that review, the asset is written down to its estimated fair value through a charge to earnings. Goodwill is measured as the excess of the cost of a business combination over the sum of the amounts assigned to identifiable intangible and other assets acquired less liabilities assumed. Goodwill is not amortized but rather assessed for impairment annually or more frequently if circumstances warrant. Management has the option of first assessing qualitative factors, such as events and circumstances, to determine whether it is more likely than not, meaning a likelihood of more than 50%, that the fair value of a reporting unit is less than its carrying amount. If, after considering all relevant events and circumstances, management determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing a quantitative impairment test is unnecessary. For the year ended December 31, 2018 , management determined that it was not more likely than not that the fair value of the reporting unit (the consolidated Company) was less than its carrying amount. If management had determined otherwise, the two-step process would have been completed to determine the impairment and necessary write-down of goodwill.
Cost Method Investments, Policy [Policy Text Block]	Other Investments The Company is a limited partner in three Small Business Investment Companies ("SBICs") which are licensed by the Small Business Administration. They provide mezzanine financing and private equity investments to small companies which may not otherwise qualify for standard bank financing. The Company records its investment in these SBICs at cost and evaluates its investment for impairment on a quarterly basis. Impairment that is considered by management to be other-than-temporary results in a write-down of the investment which is recognized as a charge to earnings. See Note 12 regarding the Bank's investment in and outstanding capital commitments to the limited partnerships.
Related Party Transactions, Policy [Policy Text Block]	Related Party Transactions Directors, officers and affiliates of the Company and the Bank have been customers of and have had transactions with the Bank, and it is expected that such persons will continue to have such transactions in the future. See Note 13 for details regarding related party transactions.
Employee Stock Ownership Plan (ESOP), Policy [Policy Text Block]	Employee Stock Ownership Plan The two loans to the ESOP are repaid from the Bank’s contributions to the ESOP and dividends payable on common stock held by the ESOP over 15 years for the first loan and 20 years for the second loan. Unearned compensation applicable to the ESOP is reflected as a reduction of shareholders’ equity on the consolidated balance sheets. Compensation expense is recognized as ESOP shares are committed to be released and is based on the average fair market value of the shares during the period. The difference between the average fair value and the cost of the shares allocated by the ESOP is recorded as an adjustment to additional paid-in capital. Unallocated ESOP shares are not considered outstanding for calculating earnings per share. Dividends paid on allocated ESOP shares are charged to retained earnings and dividends paid on unallocated ESOP shares are used to satisfy debt service. See Note 11 for additional discussion.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Equity Incentive Plan The Company measures and recognizes compensation cost relating to share-based compensation based on the grant date fair value of the equity instruments issued. Share-based compensation is recognized on a straight-line basis over the period of service or performance for the award. Reductions in compensation expense associated with forfeited options are estimated at the date of grant, and this estimated forfeiture rate is adjusted based on actual forfeiture experience. The fair value of each restricted stock allocation, equal to the market price at the date of grant, is recorded as unearned restricted shares. The fair value of each stock option award is determined on the date of grant using the Black-Scholes option pricing model, which includes several assumptions such as expected volatility, dividends, term and risk-free rate for each stock option award. See Note 11 for additional discussion.
Income Tax, Policy [Policy Text Block]	Income Taxes Deferred income tax assets and liabilities are determined using the asset and liability (or balance sheet) method. Under this method, deferred tax assets and liabilities 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 bases. 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 Tax Cuts and Jobs Act (the "Act"), which was enacted on December 22, 2017, reduced the corporate income tax rate from 35% to 21%. Accordingly, the Company revalued its net deferred tax asset resulting in a reduction in the value of its net deferred tax asset, which was recognized in the consolidated financial statements as additional income tax expense for the year ended December 31, 2017. The Company has developed a reasonable estimate of the other provisions of the Act in determining its current year income tax provision. See Note 10 for details regarding income taxes. The Company exercises significant judgment in evaluating the amount and timing of recognition of the resulting tax assets and liabilities. These judgments require the Company to make projections of future taxable income. These judgments and estimates, which are inherently subjective, are reviewed periodically as regulatory and business factors change. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that all or some portion of the deferred tax assets will not be realized. The Company does not have any uncertain tax positions which require accrual or disclosure at December 31, 2018 or 2017 . In accordance with the provisions of applicable accounting guidance, in future periods, the Company may record a liability for unrecognized tax benefits related to the recognition, derecognition or change in measurement of a tax position as a result of new tax positions, changes in management’s judgment about the level of uncertainty of existing tax positions, expiration of open income tax returns due to the statutes of limitation, status of examinations and litigation and legislative activity. The Company has elected to report future interest and penalties related to unrecognized tax benefits, if any, as income tax expense in the Company’s consolidated statements of income. An immaterial amount of interest or penalties were recorded for the years ended December 31, 2018 , 2017 or 2016 . The Company records excess tax benefits or deficiencies from share-based compensation in income tax expense in the income statement as part of the provision for income taxes beginning in 2017. Previously, such amounts were recorded to additional paid in capital. For interim reporting purposes the excess tax benefits or deficiencies from share-based compensation are recorded as discrete items in the period in which they occur. The presentation of the excess tax benefits from share-based compensation is presented as an operating activity in the statement of cash flows. In addition, when calculating incremental shares for earnings per share, the Company excludes from assumed proceeds excess tax benefits from share-based compensation that previously would have been recorded in additional paid-in capital.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive Income Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities and certain cash flow hedges, are reported as a separate component of shareholders’ equity, such items, along with net income, are components of comprehensive income. See Note 15 for components of other comprehensive loss and the related tax effects.
Stockholders' Equity, Policy [Policy Text Block]	Common Share Repurchases The Company is chartered in Maryland. Maryland law does not provide for treasury shares, rather shares repurchased by the Company constitute authorized but unissued shares. GAAP states that accounting for treasury stock shall conform to state law. Therefore, the cost of shares repurchased by the Company is allocated to common stock, additional paid-in capital and retained earnings balances.
Earnings Per Share, Policy [Policy Text Block]	Earnings Per Share Basic earnings per share is calculated by dividing the net income available to common shareholders by the weighted average number of common shares outstanding during the period. Unvested restricted shares are considered outstanding in the computation of basic earnings per share since the shares participate in dividends and the rights to the dividends are non-forfeitable. Diluted earnings per share is computed in a manner similar to basic earnings per share except the weighted average number of common shares outstanding is increased to include the incremental common shares (as computed using the treasury stock method) that would have been outstanding if all potentially dilutive common stock equivalents were issued during the period. The Company’s common stock equivalents relate solely to stock options. Repurchased common shares and unallocated common shares held by the ESOP are not deemed outstanding for earnings per share calculations. Anti-dilutive shares are common stock equivalents with weighted average exercise prices in excess of the weighted average market value for the periods presented, and are not considered in diluted earnings per share calculations. Options for 135,321 , 151,492 and 147,543 common shares for the years ended December 31, 2018 , 2017 and 2016 , respectively, were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive. The computation of earnings per share is as follows: Years Ended December 31, 2018 2017 2016 (Dollars In Thousands, Except Per Share Amounts) Net income $ 9,565 $ 5,242 $ 11,310 Weighted average common shares outstanding: Basic 11,809,899 11,859,401 11,806,927 Effect of dilutive stock options 80,133 67,118 61,195 Diluted 11,890,032 11,926,519 11,868,122 Earnings per share: Basic $ 0.81 $ 0.44 $ 0.96 Diluted $ 0.80 $ 0.44 $ 0.95
Segment Reporting, Policy [Policy Text Block]	Business Segment Reporting Public companies are required to report (i) certain financial and descriptive information about “reportable operating segments,” as defined, and (ii) certain enterprise-wide financial information about products and services, geographic areas and major customers. An operating segment is a component of a business for which separate financial information is available and evaluated regularly by the Company's management team in deciding how to allocate resources and evaluate performance. The Company’s operations are limited to financial services provided within the framework of a community bank, and decisions are generally based on specific market areas and or product offerings. Accordingly, based on the financial information presently evaluated by the Company's management team, the Company’s operations are aggregated in one reportable operating segment.
Advertising Cost, Policy, Expensed Advertising Cost [Policy Text Block]	Advertising Costs Advertising costs are expensed as incurred.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements Leases (Topic 842) - In February 2016, the Financial Accounting Standards Board ("FASB") issued amended guidance 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. Disclosures are required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. It is expected that assets and liabilities will increase based on the present value of remaining lease payments for leases in place at the adoption date; however, based on the current level of long-term leases in place, this is not expected to be material to the Company's consolidated financial statements. Financial Instruments - Credit Losses (Topic 326) - In June 2016, the FASB issued guidance that significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The update will replace today's "incurred loss" approach with an "expected loss" model. The new model, referred to as the current expected credit loss ("CECL") model, will apply to (1) financial assets subject to credit losses and measured at amortized cost and (2) certain off-balance sheet credit exposures. This includes, but is not limited to, loans, leases, held-to-maturity securities, loan commitments and financial guarantees. The CECL model does not apply to available for sale ("AFS") debt securities. For AFS debt securities with unrealized losses, entities will measure credit losses in a manner similar to current accounting guidance, except that losses will be recognized as allowances rather than reductions in the amortized cost of the securities. The update also simplifies the accounting model for purchased credit-impaired debt securities and loans. Disclosure requirements under the update have been expanded to include the entity's assumptions, models and methods for estimating the allowance for loan and lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by year of origination. The update is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted for interim and annual periods beginning after December 15, 2018. The update requires a modified retrospective transition under which a cumulative-effect to equity will be recognized in the period of adoption. Management has developed a focus team that is reviewing and monitoring additional developments and accounting guidance to determine the impact to the Company's consolidated financial statements. Management is evaluating the models and related requirements and has developed an implementation plan which includes a software solution. Intangibles - Goodwill and Other - Simplifying the Test for Goodwill Impairment (Topic 350) - In January, 2017, the FASB issued guidance aimed at simplifying the subsequent measurement of goodwill. Under these amendments, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from tax deductible goodwill on the carrying amount of a reporting unit when measuring the goodwill impairment loss, if applicable. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments in this update should be applied on a prospective basis and are effective for annual and goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements. Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) - In March 2017, the FASB issued guidance shortening the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. The amendments in this update should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosures about a change in accounting principle. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements due to limited holdings with callable features. Income Statement - Reporting Comprehensive Income (Topic 220) - In February 2018, the FASB amended Topic 220 to allow reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects resulting from the newly enacted Tax Cuts and Jobs Act. The amount of the reclassification consists of the difference between the historical corporate income tax rate and the newly enacted 21 percent corporate income tax rate. The amendment is effective for all entities for the interim and annual reporting periods beginning after December 15, 2018 and early adoption is permitted, including interim periods in those years. The Company adopted the amendment as of December 31, 2017, which resulted in a reclassification of the deferred tax asset related to the unrealized holding losses on available for sale securities of $236,000. Fair Value Measurement (Topic 820): In August 2018, the FASB issued guidance which removes, modifies and adds disclosure requirements related to fair value measurements. The amendments in this update become effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2019. Certain amendments are to be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.
