Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	NOTE 1—NATURE OF OPERATIONS Melrose Cooperative Bank (the “Bank”) is a state chartered co-operative bank which was incorporated in 1890 and is headquartered in Melrose, Massachusetts. The Bank operates its business from one banking office located in Melrose, Massachusetts. The Bank is engaged principally in the business of attracting deposits from the general public and investing those deposits in commercial and residential real estate loans, and in consumer loans. On October 21, 2014, in accordance with a Plan of Conversion (Conversion), Melrose Cooperative Bank completed a mutual-to-stock conversion pursuant to which the Bank became a wholly owned subsidiary of Melrose Bancorp, Inc. (Company), a stock holding company incorporated in February 2014. In connection with the conversion, the Company sold 2,723,409 shares of common stock, at an offering price of $10 per share, and issued an additional 106,170 shares of its common stock to the Melrose Cooperative Bank Foundation, resulting in an aggregate issuance of 2,829,579 shares of common stock. The net proceeds from the stock offering, net of offering costs of $1,716,000, amounted to $25,518,000. The Company’s stock began trading on October 22, 2014 on the NASDAQ Capital Market under the symbol “MELR”. As set forth above, in connection with the Conversion, the Bank established and funded the Melrose Cooperative Bank Foundation (Foundation) with 106,170 shares of the Company’s common stock, plus a cash contribution of $300,000. This contribution resulted in recognition of expense of $1,362,000 in the year ended December 31, 2014 based on the $10 per share offering price, plus $300,000 of cash. The Foundation supports charitable causes and community development activities in the Bank’s area of operations. Also, in connection with the Conversion, the Bank established an employee stock ownership plan (ESOP), which purchased 226,366 shares of the Company’s common stock at a price of $10 per share. The Bank at the time of the Conversion, established a Liquidation Account in an amount equal to the net worth of the Bank as of the date of the latest consolidated statement of financial condition contained in the final prospectus distributed in connection with the Conversion. The function of the Liquidation Account is to establish a priority on liquidation. The Liquidation Account will be maintained by the Company for the benefit of the eligible account holders who continue to maintain deposit accounts with the Bank following the conversion. Each eligible account holder shall, with respect to each deposit account, hold a related inchoate interest in a portion of the Liquidation Account balance, in relation to each deposit account balance at the eligibility record date, or to such balance as it may be subsequently reduced, as hereinafter provided. The initial Liquidation Account balance shall not be increased, and shall be subject to downward adjustment to the extent of any downward adjustment of any subaccount balance of any eligible account holder in accordance with the Regulations of the Division of Banks of the Commonwealth of Massachusetts. In the unlikely event of a complete liquidation of the Bank (and only in such event), following all liquidation payments to creditors (including those to depositors to the extent of their deposit accounts) each eligible account holder shall be entitled to receive a liquidating distribution from the Liquidation Account, in the amount of the then-adjusted subaccount balances for his or her deposit accounts then held, before any liquidating distribution may be made to any holder of the Bank’s capital stock.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The accounting and reporting policies of the Company and its subsidiary conform to accounting principles generally accepted in the United States of America (GAAP) and predominant practices within the banking industry. The consolidated financial statements were prepared using the accrual basis of accounting. The significant accounting policies are summarized below to assist the reader in better understanding the consolidated financial statements and other data contained herein. BASIS OF PRESENTATION: The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary the Bank, and the Bank’s wholly-owned subsidiary, MCBSC, Inc., which is used to hold investment securities. All significant intercompany accounts and transactions have been eliminated in the consolidation. USE OF ESTIMATES: In preparing consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for loan losses, impairment of investment securities and the valuation of deferred tax assets. RECLASSIFICATIONS: Certain amounts in the prior year have been reclassified to be consistent with the current year’s presentation. CASH AND CASH EQUIVALENTS: For purposes of reporting cash flows, cash and cash equivalents include cash, amounts due from banks, money market funds and federal funds sold. As of December 31, 2015 the Company has total cash and cash equivalents in the following banks: Eastern Bank $6,414,000 which represents approximately 14.0% of total stockholders’ equity State Street Bank $2,993,000 which represents approximately 6.6% of total stockholders’ equity As of December 31, 2014, the Company has total cash and cash equivalents in the following banks: Eastern Bank $7,440,000 which represents approximately 16.4% of stockholders’ equity State Street Bank $2,993,000 which represents approximately 6.6% of stockholders’ equity SECURITIES: Investments in debt securities are adjusted for amortization of premiums and accretion of discounts computed so as to approximate the interest method. Gains or losses on sales of investment securities are computed on a specific identification basis. The Company classifies debt and equity securities into one of three categories: held-to-maturity, available-for-sale, or trading. These security classifications may be modified after acquisition only under certain specified conditions. In general, securities may be classified as held-to-maturity only if the Company has the positive intent and ability to hold them to maturity. Trading securities are defined as those bought and held principally for the purpose of selling them in the near term. All other securities must be classified as available-for-sale. • Held-to-maturity securities are measured at amortized cost in the consolidated balance sheets. Unrealized holding gains and losses are not included in earnings or in a separate component of stockholders’ equity; they are merely disclosed in the notes to the consolidated financial statements. • Available-for-sale securities are carried at fair value on the consolidated balance sheets. Unrealized holding gains and losses are not included in earnings, but are reported as a net amount (less expected tax) in a separate component of stockholders’ equity until realized. • Trading securities are carried at fair value on the consolidated balance sheets. Unrealized holding gains and losses for trading securities are included in earnings. For any debt security with a fair value less than its amortized cost basis, the Company will determine whether it has the intent to sell the debt security or whether it is more likely than not it will be required to sell the debt security before the recovery of its amortized cost basis. If either condition is met, the Company will recognize a full impairment charge to earnings. For all other debt securities that are considered other-than-temporarily impaired and do not meet either condition, the credit loss portion of impairment will be recognized in earnings as realized losses. The other-than-temporary impairment related to all other factors will be recorded in other comprehensive (loss) income. Declines in marketable equity securities below their cost that are deemed other-than-temporary are reflected in earnings as realized losses. As a member of the Federal Home Loan Bank of Boston (FHLB), the Company is required to invest in $100 par value stock of the FHLB. The FHLB capital structure mandates that members must own stock as determined by their Total Stock Investment Requirement which is the sum of a member’s Membership Stock Investment Requirement and Activity-Based Stock Investment Requirement. Management evaluates the Company’s investment in FHLB stock for other-than-temporary impairment at least on a quarterly basis and more frequently when economic or market conditions warrant such evaluation. Based on its most recent analysis of the FHLB as of December 31, 2015, management deems its investment in FHLB stock to be not other-than-temporarily impaired. LOANS HELD-FOR-SALE: Loans held-for-sale are carried at the lower of cost or estimated market value in the aggregate. Net unrealized losses are recognized through a valuation allowance by charges to income. LOANS: Loans receivable that management has the intent and ability to hold until maturity or payoff are reported at their outstanding principal balances adjusted for amounts due to borrowers on unadvanced loans, any charge-offs, the allowance for loan losses and any deferred fees or costs on originated loans, or unamortized premiums or discounts on purchased loans. Loan origination and commitment fees and certain direct origination costs are deferred, and the net amount amortized as an adjustment of the related loan’s yield. The Company is amortizing these amounts over the contractual lives of the related loans. Residential real estate loans are generally placed on nonaccrual when reaching 90 days past due or in process of foreclosure. All closed-end consumer loans 90 days or more past due and any equity line in the process of foreclosure are placed on nonaccrual status. Secured consumer loans are written down to realizable value and unsecured consumer loans are charged off upon reaching 120 or 180 days past due depending on the type of loan. Commercial real estate loans and commercial business loans and leases which are 90 days or more past due are generally placed on nonaccrual status, unless secured by sufficient cash or other assets immediately convertible to cash. When a loan has been placed on nonaccrual status, previously accrued and uncollected interest is reversed against interest on loans. A loan can be returned to accrual status when collectibility of principal is reasonably assured and the loan has performed for a period of time, generally six months. Cash receipts of interest income on impaired loans are credited to principal to the extent necessary to eliminate doubt as to the collectibility of the net carrying amount of the loan. Some or all of the cash receipts of interest income on impaired loans is recognized as interest income if the remaining net carrying amount of the loan is deemed to be fully collectible. When recognition of interest income on an impaired loan on a cash basis is appropriate, the amount of income that is recognized is limited to that which would have been accrued on the net carrying amount of the loan at the contractual interest rate. Any cash interest payments received in excess of the limit and not applied to reduce the net carrying amount of the loan are recorded as recoveries of charge-offs until the charge-offs are fully recovered. ALLOWANCE FOR LOAN LOSSES: The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectibility of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. General Component: The general component of the allowance for loan losses is based on historical loss experience adjusted for qualitative factors stratified by the following loan segments: one- to four-family residential real estate, home equity loans and lines of credit, commercial real estate, construction, and consumer. Management uses a rolling average of historical losses based on a time frame appropriate to capture relevant loss data for each loan segment. This historical loss factor is adjusted for the following qualitative factors: levels/trends in delinquencies; trends in volume and terms of loans; effects of changes in risk selection and underwriting standards and other changes in lending policies, procedures and practices; experience/ability/depth of lending management and staff; and national and local economic trends and conditions. There were no changes in the Company’s policies or methodology pertaining to the general component of the allowance for loan losses during the years ending December 31, 2015 and 2014. The qualitative factors are determined based on the various risk characteristics of each loan segment. Risk characteristics relevant to each portfolio segment are as follows: One- to four-family residential real estate: The Company generally does not originate loans with a loan-to-value ratio greater than 80% and does not grant subprime loans. Loans with loan-to-value ratios greater than 80% require private mortgage insurance. 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. Loans in this segment also include home equity loans and lines of credit. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Commercial real estate: Loans in this segment are primarily income-producing properties throughout Massachusetts. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy as evidenced by increased vacancy rates, which in turn, will have an effect on the credit quality in this segment. Loans in this segment also include loans secured by multifamily dwellings. Management periodically obtains rent rolls and continually monitors the cash flows of these loans. Construction loans: Loans in this segment primarily include speculative real estate development loans for which payment is derived from sale of the property. Credit risk is affected by cost overruns, time to sell at an adequate price, and market conditions. Consumer loans: Loans in this segment are generally secured and repayment is dependent on the credit quality of the individual borrower. Loans in this segment include auto loans and other consumer loans. Allocated Component: The allocated component relates to loans that are classified as impaired. Impairment is measured on a loan by loan basis for commercial real estate and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. An allowance is established when the discounted cash flows (or collateral value) of the impaired loan is lower than the carrying value of that loan. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and one- to four-family residential real estate loans for impairment disclosures, unless such loans are subject to a troubled debt restructuring agreement. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The Company periodically may agree to modify the contractual terms of loans. When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a troubled debt restructuring (“TDR”). All TDRs are initially classified as impaired. Unallocated Component: An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating allocated and general reserves in the portfolio. PREMISES AND EQUIPMENT: Land is carried at cost. Buildings and equipment are stated at cost, less accumulated depreciation and amortization. Cost and related allowances for depreciation and amortization of premises and equipment retired or otherwise disposed of are removed from the respective accounts with any gain or loss included in income or expense. Depreciation and amortization are calculated principally on the straight-line method over the estimated useful lives of the assets. Estimated lives are 15 to 40 years for buildings and 3 to 10 years for furniture and equipment. OTHER REAL ESTATE OWNED AND IN-SUBSTANCE FORECLOSURES: Foreclosed real estate is primarily comprised of property acquired through a foreclosure proceeding or acceptance of a deed-in-lieu of foreclosure. Foreclosed real estate is initially recorded at fair value, less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less costs to sell. Revenues and expenses from operations and changes in the valuation allowance are included in expenses related to foreclosed real estate. The Company classifies commercial loans as in-substance repossessed or foreclosed if the company receives physical possession of the debtor’s assets regardless of whether formal foreclosure proceedings take place. An in-substance repossession or foreclosure occurs, and the Company is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan upon either; (1) obtaining legal title to the residential real estate property upon completion of a foreclosure; or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. BANK-OWNED LIFE INSURANCE: The Company has purchased insurance policies on the lives of certain directors, executive officers and employees. Bank-owned life insurance policies are reflected on the consolidated balance sheets at cash surrender value. Changes in net cash surrender value of the policies, as well as insurance proceeds received, are reflected in non-interest income on the consolidated statements of income and are not subject to income taxes. ADVERTISING: The Company directly expenses costs associated with advertising as they are incurred. Advertising expense for the years ended December 31, 2015 and 2014 amounted to $143,000 and $120,000, respectively. INCOME TAXES: The Company recognizes income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are established for the temporary differences between the accounting basis and the tax basis of the Company’s assets and liabilities at enacted tax rates expected to be in effect when the amounts related to such temporary differences are realized or settled. EMPLOYEE STOCK OWNERSHIP PLAN: Compensation expense for the Employee Stock Ownership Plan (“ESOP”) is recorded at an amount equal to the shares allocated by the ESOP multiplied by the average fair value of the shares during the period. The Company recognizes compensation expense based upon the Company’s estimate of the number of shares expected to be allocated by the ESOP. Unearned compensation applicable to the ESOP is reflected as a reduction of stockholders’ equity in the consolidated balance sheet. The difference between the average fair value and the cost of shares allocated by the ESOP is recorded as an adjustment to additional paid-in-capital. EARNINGS PER SHARE (EPS): When presented, basic EPS is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. For the purposes of computing diluted EPS, the treasury stock method is used. Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. The calculation of basic and diluted EPS is presented below. There were no common stock equivalents in the twelve month period ending December 31, 2015. Year Ended Net income (In Thousands, except share data) $ 658 Basic Common Shares: Weighted average common shares outstanding 2,825,847 Weighted average unallocated ESOP shares (218,820 ) Basic and diluted weighted average shares outstanding 2,607,027 Basic earnings per share $ 0.25 Diluted earnings per share (1) $ 0.25 (1) As of and during the year ended December 31, 2015, there were no potentially dilutive securities or contracts to issue common stock. Because the formation of the Company was completed on October 22, 2014, earnings per share data is not meaningful for the year ended December 31, 2014 and is therefore not presented. FAIR VALUES OF FINANCIAL INSTRUMENTS: Accounting Standards Codification (ASC) 825, “Financial Instruments,” requires that the Company disclose the estimated fair value for its financial instruments. Fair value methods and assumptions used by the Company in estimating its fair value disclosures are as follows: Cash and cash equivalents: The carrying amounts reported in the balance sheets for cash and cash equivalents approximate those assets’ fair values. Securities: Fair values for securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. Loans held-for-sale: Fair values of loans held-for-sale are based on commitments on hand from investors or prevailing market prices. Loans receivable: For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. The fair values for other loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Accrued interest receivable: The carrying amount of accrued interest receivable approximates its fair value. Deposit liabilities: The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings and money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for fixed-rate certificate accounts are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on certificate accounts. Off-balance sheet instruments: The fair value of commitments to originate loans is estimated using the fees currently charged to enter similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments and the unadvanced portion of loans, fair value also considers the difference between current levels of interest rates and the committed rates. RECENT ACCOUNTING PRONOUNCEMENTS: As an “emerging growth company,” as defined in Title 1 of Jumpstart Our Business Startups (JOBS) Act, the Company has elected to use the extended transition period to delay adoption of new or reissued accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. Accordingly, the consolidated financial statements may not be comparable to the financial statements of public companies that comply with such new or revised accounting standards. As of December 31, 2015, there is no significant difference in the comparability of the financial statements as a result of this extended transition period. In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-05, “Intangibles – Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” This ASU provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. Under the extended transition period for an emerging growth company, this ASU is effective for annual periods beginning after December 15, 2015, and interim periods in annual periods beginning after December 31, 2016. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In May 2015, the FASB issued ASU 2015-07: “Fair Value Measurement (Topic 820) – Disclosure for Investments in Certain Entities That Calculate Net Asset Value per Share (or its Equivalent).” The objective of this update is to address the diversity in practice related to how certain investments measured at net asset value with redemption dates in the future are categorized within the fair value hierarchy. The amendments in this update remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The amendments also remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. Under the extended transition period for an emerging growth company, the amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments in this ASU address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments and makes targeted improvements to GAAP as follows: 1. Require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. However, the entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same manner. 2. Simplify the impairment assessment of equity investments without determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. 3. Eliminate the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. 4. Require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 5. Require an entity to present separately in other comprehensive income the portion of the total change in fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. 6. Require separate presentation of financial assets and financial liabilities by measurement category and form of financial assets (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. 7. Clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. Under the extended transition period for an emerging growth company, the amendments in this Update are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption of item 5 above is permitted as of the fiscal years beginning after December 31, 2019, or interim periods for which financial statements have not been issued. Early adoption of all other amendments in this ASU is not permitted. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” This ASU was issued to increase transparency and comparability among organizations by requiring reporting entities to recognize all leases, including operating, as lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. Under the extended transition period for an emerging growth company, the amendments in this ASU are effective for fiscal years beginning after December 31, 2019, and interim periods within fiscal years being after December 15, 2020. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements.

Investments, Debt and Equity Securities [Abstract]
Investments in Available-For-Sale Securities	NOTE 3—INVESTMENTS IN AVAILABLE-FOR-SALE SECURITIES Debt and equity securities have been classified in the consolidated balance sheets according to management’s intent. The amortized cost basis of securities and their approximate fair values are as follows: Amortized Gross Gross Fair (In Thousands) December 31, 2015: U.S. Government and federal agency obligations $ 8,851 $ 7 $ 88 $ 8,770 Debt securities issued by states of the United States and political subdivisions of the states 2,408 8 18 2,398 Corporate bonds and notes 13,540 12 44 13,508 Preferred stock 3,000 31 2 3,029 Mortgage-backed securities 2,232 — 66 2,166 Marketable equity securities 13,183 2,125 36 15,272 $ 43,214 $ 2,183 $ 254 $ 45,143 December 31, 2014: U.S. Government and federal agency obligations $ 4,007 $ 3 $ 20 $ 3,990 Debt securities issued by states of the United States and political subdivisions of the states 544 — 4 540 Corporate bonds and notes 15,238 38 35 15,241 Preferred stock 3,000 — 96 2,904 Mortgage-backed securities 2,138 — 23 2,115 Marketable equity securities 14,780 2,641 436 16,985 $ 39,707 $ 2,682 $ 614 $ 41,775 The scheduled maturities of debt securities as of December 31, 2015 are as follows: Fair (In Thousands) Due within one year $ 3,257 Due after one year through five years 16,231 Due after five years through ten years 2,266 Due after ten years 3,107 Mortgage-backed securities 2,166 Asset-backed securities 1,846 $ 28,873 Not included in the maturity table above is preferred stock with no stated maturity of $998,000 at December 31, 2015. There were no securities of issuers whose aggregate carrying amount exceeded 10% of stockholders’ equity at December 31, 2015. During the year ended December 31, 2015 proceeds from the sale of available-for-sale securities, amounted to $2.9 million. The gross realized gains on these sales amounted to $490,000 and the gross realized losses were $81,000. The tax expense applicable to these net realized gains amounted to $164,000. During the year ended December 31, 2014, there were no sales of available-for-sale securities. The Company had no pledged securities as of December 31, 2015 and December 31, 2014. The aggregate fair value and unrealized losses of securities that have been in a continuous unrealized loss position for less than twelve months and for twelve months or more, and are not other-than-temporarily impaired, are as follows: Less than 12 months 12 Months or Longer Total Fair Unrealized Fair Unrealized Fair Unrealized (In Thousands) December 31, 2015 U.S. government and federal agency obligations $ 5,366 $ 59 $ 1,403 $ 29 $ 6,769 $ 88 Debt securities issued by states of the United States and political subdivisions of the states 1,176 9 505 9 1,681 18 Corporate bonds and notes 9,012 38 993 6 10,005 44 Preferred stock 998 2 — — 998 2 Mortgage-backed securities 1,608 40 558 26 2,166 66 Marketable equity securities 5,160 36 — — 5,160 36 Total temporarily impaired securities $ 23,320 $ 184 $ 3,459 $ 70 $ 26,779 $ 254 December 31, 2014: U.S. government and federal agency obligations $ 2,006 $ 6 $ 1,486 $ 14 $ 3,492 $ 20 Debt securities issued by states of the United States and political subdivisions of the states 540 4 — — 540 4 Corporate bonds and notes 4,978 11 1,974 24 6,952 35 Preferred stock — — 2,904 96 2,904 96 Mortgage-backed securities 2,115 23 — — 2,115 23 Marketable equity securities — — 10,306 436 10,306 436 Total temporarily impaired securities $ 9,639 $ 44 $ 16,670 $ 570 $ 26,309 $ 614 December 31, 2015 The Company conducts periodic reviews of investment securities with unrealized losses to evaluate whether the impairment is other-than-temporary. The Company’s review for impairment generally includes a determination of the cause, severity and duration of the impairment; and an analysis of both positive and negative evidence available. The Company also determines if it has the ability and intent to hold the investment for a period of time sufficient to allow for anticipated recovery to cost basis. Based on the Company’s recent review of securities in the investment portfolio, management deemed securities with unrealized losses as of December 31, 2015 to be temporarily impaired and has the ability and intent to hold these securities until recovery to cost basis occurs. A summary of this review is as follows. Unrealized losses on U.S. Government and federal agency obligations amounted to $88,000 and consisted of eleven securities. Unrealized losses on corporate bonds and notes amounted to $44,000 and consisted of eighteen securities. Unrealized losses on municipal bonds amounted to $18,000 and consisted of four securities. Unrealized losses on mortgage-backed securities amounted to $66,000 and consisted of four securities. The unrealized losses on all of these debt securities were each individually less than 3.0% of amortized cost basis, and the unrealized losses were primarily due to changes in interest rates. In regard to corporate debt, the Company also considers the issuer’s current financial condition and its ability to make future scheduled interest and principal payments on a timely basis in assessing other-than-temporary impairment. The Company’s investment in impaired preferred stocks consists of one investment in Public Storage Inc., which has an unrealized loss of $2,000, or 0.2% of amortized cost. This loss was due to changes in interest rates. The Company reviewed this investment for impairment by considering factors such as, among other things, the financial condition and ability of the issuer to continue to pay dividends, and any specific events that may affect the operations of the issuer. Unrealized losses on marketable equity securities consist of three mutual funds. One mutual fund invests mainly in short-term bonds, with unrealized losses amounting to $14,000, or 1.3% of cost basis; and two mutual funds invest in Government National Mortgage Association (GNMA) securities with a total combined unrealized loss of $22,000, or approximately 0.5% of each mutual fund’s cost basis. These three mutual funds have been in an unrealized loss position ranging from one to six months. The cause of the impairment in these mutual funds is due to changes in interest rates and the continued underperformance of most fixed income asset classes during the year ended December 31, 2015. The Company considered several factors in reviewing these mutual fund investments, including underlying investment performance, composition and rating of the securities in the mutual fund, and management of the mutual funds’ issuer. During 2015, there were five marketable equity securities that were declared other-than-temporarily impaired and for which an impairment loss of $461,000 was recognized. There were 4 marketable equity securities sold with total gain of $409,000 in 2015. The net loss was $52,000 for the year ending December 31, 2015.

During the years ended December 31, 2015 and 2014 there were no loans that met the definition of a troubled debt restructured loan in ASC 310-10-50. At December 31, 2015, there was one loan secured by one- to four-family residential real estate and one home equity line of credit totaling $265,000 that were on non-accrual status. At December 31, 2015, there are no residential real estate loans foreclosed upon. There are two consumer mortgage loans to one borrower in the process of foreclosure totaling $265,000. Credit Quality Information The Company utilizes a seven grade internal loan rating system for commercial real estate and construction loans as follows: Loans rated 1—3: Loans in these categories are considered “pass” rated loans with low to average risk. Loans rated 4: Loans in this category are considered “special mention.” These loans are starting to show signs of potential weakness and are being closely monitored by management. Loans rated 5: Loans in this category are considered “substandard.” Generally, a loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. There is a distinct possibility that the Company will sustain some loss if the weakness is not corrected. Loans rated 6: Loans in this category are considered “doubtful.” Loans classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable. Loans rated 7: Loans in this category are considered uncollectible (“loss”) and of such little value that their continuance as loans is not warranted. On an annual basis, or more often if needed, the Company formally reviews the ratings on all commercial real estate and construction loans. For all residential real estate, home equity and consumer loans, the Company initially assesses credit quality based upon the borrower’s ability to service the debt and subsequently monitors these loans based upon the borrower’s payment activity. As of December 31, 2015, one- to four- family residential real estate loans with balances totaling $366,000 and a home equity loan and line of credit with a balance of $197,000 had a risk rating of “substandard” and all other loans outstanding had a risk rating of “pass.” As of December 31, 2014, one- to four- family residential real estate loans with balances totaling $394,000 and home equity loans and lines of credit totaling $202,000 had a risk rating of “substandard” and all other loans outstanding had a risk rating of “pass.”

As of December 31, 2015, the Company had a remaining deferred tax asset of $483,000. A valuation allowance of $90,000 has been established against the deferred tax assets related to the uncertain utilization of the charitable contribution carryforward created primarily by the donation to the Foundation. The judgment applied by management considers the likelihood that sufficient taxable income will be realized within the carryforward period in light of its tax planning strategies and changes in market conditions. The charitable contribution carryforward of $1,194,000 at December 31, 2015 expires in 2019 and the related tax benefit, net of the valuation allowance, included in net deferred tax assets is $393,000. It is the Company’s policy to provide for uncertain tax positions and the related interest and penalties based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. As of December 31, 2015 and 2014, there were no material uncertain tax positions related to federal and state income tax matters. The Company is currently open to audit under the statute of limitations by the Internal Revenue Service and state taxing authorities for the years ended December 31, 2012 through December 31, 2015. Interest and penalties, if any, are recorded as income tax expense.

The Plan’s Employer Identification Number is 04-6035593 and the Plan Number is 334. The Plan operated as a multi-employer plan for accounting purposes and as a multiple-employer plan under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code. There were no collective bargaining agreements in place that required contributions to the Plan. The Plan is a single plan under Internal Revenue Code Section 413(c) and, as a result, all of the assets stand behind all of the liabilities. Accordingly, under the Plan, contributions made by a participating employer may be used to provide benefits to participants of other participating employers. The Plan covered all salaried employees who were at least twenty-one years of age with at least one year of employment with the Bank. The plan was funded by contributions based on actuarial calculations. As is the case with multi-employer plans, separate actuarial valuations are not made with respect to each employer. Effective April 30, 2014, the Bank froze benefit accruals earned by participants and has withdrawn from the plan. The Bank was later informed by CBERA that it has no future obligations to fund the Plan. The funded status (market value of plan assets divided by the funding target) was 86% as of January 1, 2014. During the year ended December 31, 2014, the Bank contributed $44,000 to the Plan. 401(k) Savings Plan Prior to April 1, 2014, the Bank participated in a 401(k) savings plan through CBERA. Eligible employees were able to contribute up to 75% of their salary, subject to IRS limitations, which could have been matched up to 5% by the Bank on a dollar for dollar basis. The Company’s expense under this 401(k) plan was $16,000 for the year ended December 31, 2014. Since April 1, 2014, the Company has participated in a 401(k) savings plan through Pentegra. Eligible employees may contribute up to 100% of their salary, subject to IRS limitations, which can be matched up to 5% by the Company on a dollar for dollar basis. The Company’s expense under this 401(k) plan was $70,000 and $46,000 for the years ended December 31, 2015 and 2014, respectively. Supplemental Executive Retirement Benefits The Bank adopted Supplemental Executive Retirement Agreements for two executive officers. These agreements were designed to supplement the benefits available through the Bank’s retirement plan. The liability for the benefits amounted to $176,000 at December 31, 2014, and is included in other liabilities. The expense recognized for these benefits was $5,000 for the year ended December 31, 2014. These agreements were frozen as of February 1, 2014. During 2015, payments totaling $88,000 were made to participants under the plan, and the remaining liability amounted to $88,000 at December 31, 2015. The two executive officers now participate in a new plan as follows. Effective January 1, 2014, the Company established a Supplemental Executive Retirement Plan (SERP Plan). Under the SERP Plan, on a yearly basis, the Company shall credit the participant’s SERP account with the annual contribution specified in the participant’s participation agreement, based on a fixed percent of each participant’s annual salary. The SERP account is an unfunded liability due to each participant and is accruing interest. For the plan years ended December 31, 2015 and 2014, the related liability amounted to $138,000 and $68,000, respectively, and is included in other liabilities. Participants vest in full upon attaining five years of service from the date of participation, attainment of benefit age, or following a change in control. For the years ended December 31, 2015 and 2014, expense recognized under the plan for these benefits was $70,000 and $68,000, respectively. Employee Stock Ownership Plan The Company has adopted a tax-qualified employee stock ownership plan (“ESOP”) for the benefit of eligible employees. The Company completed its initial public offering and in connection with the conversion transaction, 226,366 shares of Company common stock were purchased by the ESOP at $10.00 per share. The ESOP funded its stock purchase through a loan from the Company equal to 100% of the aggregate purchase price of the common stock. The ESOP trustee will repay the loan principally through the Bank’s contributions to the ESOP and, possibly, dividends paid on common stock held by the plan over the loan term of 29.2 years. The trustee holds the shares purchased in a loan suspense account and will release the shares from the suspense account on a pro rata basis as it repays the loan. The trustee will allocate the shares released among active participants on the basis of each active participant’s proportional share of compensation compared to all active participants for the pan year. Participants vest in their benefit at a rate of 20% per year and will be full vested upon completion of five years of credited service. Generally, participants will receive distributions from the ESOP upon separation from service. The trustee will reallocate any unvested shares of common stock forfeited by participants upon their separation from service among the remaining participants in the plan. Eligible employees who were employed with the Bank shall receive credit for vesting purposes for each year of continuous employment prior to adoption of the ESOP. The Company records compensation expense for the ESOP at an amount equal to the shares allocated by the ESOP multiplied by the average fair market value of shares during the period. At December 31, 2015, the remaining principal balance on the ESOP debt was $2,116,000 and the number of shares held by the ESOP was 226,366. Total compensation expense recognized in connection with the ESOP was $107,000 and $99,000 for the years ended December 31, 2015 and 2014, respectively. The remaining principal balance on the ESOP debt as of December 31, 2015 is payable as follows: Years Ending December 31, Amount (In Thousands) 2016 $ 47 2017 49 2018 51 2019 52 2020 54 Thereafter 1,863 $ 2,116 Shares held by the ESOP are as follows as of December 31: 2015 2014 Allocated 15,092 7,546 Unallocated 211,274 218,820 Shares held by ESOP 226,366 226,366 The fair value of unallocated ESOP shares was $3,228,000 at December 31, 2015. 2015 Equity Incentive Plan The Company adopted the Melrose Bancorp, Inc. 2015 Equity Incentive Plan (the “2015 Equity Incentive Plan”), to provide officers, employees, and directors of the Company and the Bank with additional incentives to promote growth and performance. In addition, the 2015 Equity Incentive Plan is intended to further align the interest of our directors and management with the interests of our stockholders by potentially increasing the ownership interests of directors and officers in the common stock of Melrose Bancorp, Inc. Subject to permitted adjustments for certain corporate transactions, the 2015 Equity Incentive Plan authorizes the issuance or delivery to participants of up to 396,140 shares of Melrose Bancorp, Inc. common stock pursuant to grants of incentives and non-statutory stock options, restricted stock awards and restricted stock units. Of this number, the maximum number of shares of Melrose Bancorp, Inc. common stock that may be issued under the 2015 Equity Incentive Plan pursuant to the exercise of stock options is 282,957 shares, and the maximum number of shares of Melrose Bancorp, Inc. common stock that may be issued as restricted stock awards or restricted stock units is 113,183 shares. These amounts represent 10% and 4%, respectively, of the shares of the Company’s common stock that were issued in our initial public offering, including shares contributed to Melrose Cooperative Bank Foundation, on October 21, 2014 in connection with the Bank’s mutual to stock conversion. The 2015 Equity Incentive Plan will be administered by the members of the Melrose Bancorp, Inc.’s Compensation Committee (the “Committee”) who are “Disinterested Board Members,” as defined in the plan. The Committee may determine the type and terms and conditions of the awards under the 2015 Equity Incentive Plan, which shall be set forth in an award agreement delivered to each participant. Awards may be granted as incentive and non-statutory stock options, restricted stock awards and restricted stock units or any combination thereof. Employees and directors of Melrose Bancorp, Inc. or its subsidiaries are eligible to receive awards under the 2015 Equity Incentive Plan, except that non-employees may not be granted incentive stock options. The 2015 Equity Incentive Plan was effective upon approval at the November 23, 2015 annual meeting. The plan will remain in effect as long as any awards under it are outstanding: however; no awards may be granted under the 2015 Equity Incentive Plan on or after the 10-year anniversary of the effective date of the plan. At any time, the Board of Directors may terminate the 2015 Equity Incentive Plan. However, any termination of the 2015 Equity Incentive Plan will not affect outstanding awards. To date, no awards have been issued or granted. Other Agreements The Company has entered into employment agreements and change in control agreements with certain executive officers which would provide the executive officers with severance payments based on salary, and the continuation of other benefits, upon a change in control as defined in the agreements.

Investments, All Other Investments [Abstract]
Financial Instruments	NOTE 10 - FINANCIAL INSTRUMENTS The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to originate loans and unadvanced funds on loans. The instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheets. The contract amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for loan commitments is represented by the contractual amounts of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Commitments to originate loans are agreements to lend to a customer provided 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 Bank upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include secured interests in mortgages, accounts receivable, inventory, property, plant and equipment and income-producing properties. Notional amounts of financial instrument liabilities with off-balance sheet credit risk are as follows: December 31, December 31, 2015 2014 (In Thousands) Commitments to originate loans $ 5,214 $ 3,713 Unused lines of credit 11,986 11,065 Due to borrowers on unadvanced construction loans 1,796 323 $ 18,996 $ 15,101

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 11 - FAIR VALUE MEASUREMENTS ASC 820-10, “Fair Value Measurement—Overall,” provides a framework for measuring fair value under generally accepted accounting principles. This guidance also allows an entity the irrevocable option to elect fair value for the initial and subsequent measurement for certain financial assets and liabilities on a contract-by-contract basis. In accordance with ASC 820-10, the Company groups its financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1 - Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange. Level 1 also includes U.S. Treasury, other U.S. Government and agency mortgage-backed securities that are traded by dealers or brokers in active markets. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 - Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained from third party pricing services for identical or comparable assets or liabilities. Level 3 - Valuations for assets and liabilities that are derived from other methodologies, including option pricing models, discounted cash flow models and similar techniques, are not based on market exchange, dealer, or broker traded transactions. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets and liabilities. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Company’s financial assets and financial liabilities carried at fair value for December 31, 2015 and December 31, 2014. The Company did not have any significant transfers of assets between levels 1 and 2 of the fair value hierarchy during the years ended December 31, 2015 and 2014. The Company’s marketable equity securities and preferred stocks are generally classified within level 1 of the fair value hierarchy because they are valued using quoted market prices. The Company’s investment in debt securities available-for-sale is generally classified within level 2 of the fair value hierarchy. For these securities, we obtain fair value measurements from independent pricing services. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. treasury yield curve, trading levels, market consensus prepayment speeds, credit information and the instrument’s terms and conditions. Level 3 is for positions that are not traded in active markets or are subject to transfer restrictions, valuations are adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate is used. Subsequent to inception, management only changes level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying investment or comparable entities, subsequent rounds of financing, recapitalization and other transactions across the capital structure, offerings in the equity or debt markets, and changes in financial ratios or cash flows. The Company’s impaired loans, if any, are reported at the fair value of the underlying collateral if repayment is expected solely from the collateral. Collateral values are estimated using level 2 inputs based upon appraisals of similar properties obtained from a third party. For level 3 inputs, fair value is based upon management estimates of the value of the underlying collateral or the present value of the expected cash flows. The following summarizes assets measured at fair value on a recurring basis: Fair Value Measurements at Reporting Date Using: Total Quoted Prices in Significant Significant (In Thousands) December 31, 2015: U.S. Government and federal agency obligations $ 8,770 $ — $ 8,770 $ — Debt securities issued by states of the United States and political subdivisions of the states 2,398 — 2,398 — Corporate bonds and notes 13,508 — 13,508 — Preferred stock 3,029 3,029 — — Mortgage-backed securities 2,166 — 2,166 — Marketable equity securities 15,272 15,272 — — Totals $ 45,143 $ 18,301 $ 26,842 $ — December 31, 2014: U.S. Government and federal agency obligations $ 3,990 $ — $ 3,990 $ — Debt securities issued by states of the United States and political subdivisions of the states 540 — 540 — Corporate bonds and notes 15,241 — 15,241 — Preferred stock 2,904 2,904 — — Mortgage-backed securities 2,115 — 2,115 — Marketable equity securities 16,985 16,985 — — Totals $ 41,775 $ 19,889 $ 21,886 $ — Under certain circumstances the Company makes adjustments to fair value for its assets and liabilities although they are not measured at fair value on an ongoing basis.

Other Comprehensive (Loss) Income	NOTE 12 - OTHER COMPREHENSIVE (LOSS) INCOME Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities are reported as a separate component of the stockholders’ equity section of the consolidated balance sheets, such items, along with net income, are components of comprehensive income. The components of other comprehensive (loss) income included in stockholders’ equity are as follows: For the years ended December 31, 2015 2014 (In Thousands) Net unrealized holding (losses) gains on available-for-sale securities $ (190 ) $ 1,028 Reclassification adjustment for net realized losses in net income (1) 52 — Other comprehensive (loss) income before income tax effect (138 ) 1,028 Income tax expense (benefit) 68 (385 ) Other comprehensive (loss) income, net of tax $ (70 ) $ 643 (1) Reclassification adjustments include net realized securities losses. Realized losses have been reclassified out of accumulated other comprehensive income and affect certain captions in the consolidated statements of income (loss) as follows: pre-tax amount is included in gains on sales of securities, net and write-downs of securities, the tax benefit of $20,000 Accumulated other comprehensive income as of December 31, 2015 and 2014 consists of net unrealized holding gains on available-for-sale securities, net of taxes.

Regulatory Matters

Regulatory Matters	12 Months Ended

Banking and Thrift [Abstract]
Regulatory Matters	NOTE 13 - REGULATORY MATTERS The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Effective January 1, 2015, (with a phase-in period of two to four years for certain components), the Bank became subject to new capital regulations adopted by the Board of Governors of the Federal Reserve System (“FRB”) and the FDIC, which implement the Basel III regulatory capital reforms and the changes required by the Dodd-Frank Act. The new regulations require a new common equity Tier 1 (“CET1”) capital ratio of 4.5%, increase the minimum Tier 1 capital to risk-weighted assets ratio to 6.0% from 4.0%, require a minimum total capital to risk-weighted assets ratio of 8.0% and require a minimum Tier 1 leverage ratio of 4.0%. CET1 generally consists of common stock and retained earnings, subject to applicable adjustments and deductions. Under new prompt corrective action regulations, in order to be considered “well capitalized,” the Bank must maintain a CET1 capital ratio of 6.5% (new) and a Tier 1 ratio of 8.0% (increased from 6.0%), a total risk based capital ratio of 10.0% (unchanged) and a Tier 1 leverage ratio of 5.0% (unchanged). In addition, the regulations establish a capital conservation buffer above the required capital ratios that phases in beginning January 1, 2016 at 0.625% of risk-weighted assets and increases each year by 0.625% until it is fully phased in at 2.5% effective January 1, 2019. Beginning January 1, 2016, failure to maintain the capital conservation buffer will limit the ability of the Bank and the Company to pay dividends, repurchase shares or pay discretionary bonuses. The new regulation implemented changes to what constitutes regulatory capital. Certain instruments will no longer constitute qualifying capital, subject to phase-out periods. In addition, Tier 2 capital is no longer limited to the amount of Tier 1 capital included in total capital. Mortgage servicing rights, certain deferred tax assets and investments in unconsolidated subsidiaries over designated percentages of CET1 will be deducted from capital. The Bank has elected to permanently opt-out of the inclusion of accumulated other comprehensive income (loss) in capital calculations, as permitted by regulations. This opt-out will reduce the impact of market volatility on the Bank’s regulatory capital ratios. The new regulations also changed the risk weights of certain assets, including an increase in the risk weight of certain high volatility commercial real estate acquisition, development and construction loans and non-residential mortgage loans that are 90 days past due or on non-accrual status to 150% from 100%, a credit conversion factor for the unused portion of the commitments with maturities of less than one year that are not cancellable to 20% from 0%, an increase in the risk weight for mortgage servicing rights and deferred tax assets that are not deducted from capital to 250% from 100%, and an increase in the risk weight for equity exposures to 600% from 100%. Management believes, as of December 31, 2015, that the Bank meets all capital adequacy requirements to which it is subject. As of December 31, 2015, the most recent notification from the FDIC categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank must maintain minimum Common Equity Tier 1, total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the following table. There were no conditions or events since that notification that management believes have changed the Bank’s category. The Bank’s actual capital amounts and ratios are also presented in the table. Actual For Capital Adequacy Purposes To Be Well Capitalized Under Amount Ratio Amount Ratio Amount Ratio (Dollars In Thousands) As of December 31, 2015: Total Capital (to Risk Weighted Assets) $ 33,580 24.78 % $ 10,839 8.0 % $ 13,549 10.0 % Tier 1 Capital (to Risk Weighted Assets) 32,060 23.66 8,129 6.0 10,839 8.0 Common Equity Tier 1 Capital (to Risk Weighted Assets) 32,060 23.66 6,097 4.5 8,807 6.5 Tier 1 Capital (to Average Assets) 32,060 14.45 8,877 4.0 11,096 5.0 As of December 31, 2014: Total Capital (to Risk Weighted Assets) $ 32,874 27.53 % $ 9,552 8.0 % $ 11,940 10.0 % Tier 1 Capital (to Risk Weighted Assets) 31,364 26.27 4,776 4.0 7,164 6.0 Tier 1 Capital (to Average Assets) 31,364 14.78 8,332 4.0 10,415 5.0

In general, stock repurchase plans allow us to proactively manage our capital position and return excess capital to shareholders. Shares purchased under such plans also provide us with shares of common stock necessary to satisfy obligations related to stock compensation awards. In November 2015 , In 2015, 42,000 shares of common stock were repurchased at an average cost of $14.60. In January and February of 2016, a total of 85,600 shares of common stock were repurchased at an average cost of $15.05.

Summary of Significant Accoun27

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION: The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary the Bank, and the Bank’s wholly-owned subsidiary, MCBSC, Inc., which is used to hold investment securities. All significant intercompany accounts and transactions have been eliminated in the consolidation.
USE OF ESTIMATES	USE OF ESTIMATES: In preparing consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for loan losses, impairment of investment securities and the valuation of deferred tax assets.
RECLASSIFICATIONS	RECLASSIFICATIONS: Certain amounts in the prior year have been reclassified to be consistent with the current year’s presentation.
CASH AND CASH EQUIVALENTS	CASH AND CASH EQUIVALENTS: For purposes of reporting cash flows, cash and cash equivalents include cash, amounts due from banks, money market funds and federal funds sold. As of December 31, 2015 the Company has total cash and cash equivalents in the following banks: Eastern Bank $6,414,000 which represents approximately 14.0% of total stockholders’ equity State Street Bank $2,993,000 which represents approximately 6.6% of total stockholders’ equity As of December 31, 2014, the Company has total cash and cash equivalents in the following banks: Eastern Bank $7,440,000 which represents approximately 16.4% of stockholders’ equity State Street Bank $2,993,000 which represents approximately 6.6% of stockholders’ equity
SECURITIES	SECURITIES: Investments in debt securities are adjusted for amortization of premiums and accretion of discounts computed so as to approximate the interest method. Gains or losses on sales of investment securities are computed on a specific identification basis. The Company classifies debt and equity securities into one of three categories: held-to-maturity, available-for-sale, or trading. These security classifications may be modified after acquisition only under certain specified conditions. In general, securities may be classified as held-to-maturity only if the Company has the positive intent and ability to hold them to maturity. Trading securities are defined as those bought and held principally for the purpose of selling them in the near term. All other securities must be classified as available-for-sale. • Held-to-maturity securities are measured at amortized cost in the consolidated balance sheets. Unrealized holding gains and losses are not included in earnings or in a separate component of stockholders’ equity; they are merely disclosed in the notes to the consolidated financial statements. • Available-for-sale securities are carried at fair value on the consolidated balance sheets. Unrealized holding gains and losses are not included in earnings, but are reported as a net amount (less expected tax) in a separate component of stockholders’ equity until realized. • Trading securities are carried at fair value on the consolidated balance sheets. Unrealized holding gains and losses for trading securities are included in earnings. For any debt security with a fair value less than its amortized cost basis, the Company will determine whether it has the intent to sell the debt security or whether it is more likely than not it will be required to sell the debt security before the recovery of its amortized cost basis. If either condition is met, the Company will recognize a full impairment charge to earnings. For all other debt securities that are considered other-than-temporarily impaired and do not meet either condition, the credit loss portion of impairment will be recognized in earnings as realized losses. The other-than-temporary impairment related to all other factors will be recorded in other comprehensive (loss) income. Declines in marketable equity securities below their cost that are deemed other-than-temporary are reflected in earnings as realized losses. As a member of the Federal Home Loan Bank of Boston (FHLB), the Company is required to invest in $100 par value stock of the FHLB. The FHLB capital structure mandates that members must own stock as determined by their Total Stock Investment Requirement which is the sum of a member’s Membership Stock Investment Requirement and Activity-Based Stock Investment Requirement. Management evaluates the Company’s investment in FHLB stock for other-than-temporary impairment at least on a quarterly basis and more frequently when economic or market conditions warrant such evaluation. Based on its most recent analysis of the FHLB as of December 31, 2015, management deems its investment in FHLB stock to be not other-than-temporarily impaired.
LOANS HELD-FOR-SALE	LOANS HELD-FOR-SALE: Loans held-for-sale are carried at the lower of cost or estimated market value in the aggregate. Net unrealized losses are recognized through a valuation allowance by charges to income.
LOANS	LOANS: Loans receivable that management has the intent and ability to hold until maturity or payoff are reported at their outstanding principal balances adjusted for amounts due to borrowers on unadvanced loans, any charge-offs, the allowance for loan losses and any deferred fees or costs on originated loans, or unamortized premiums or discounts on purchased loans. Loan origination and commitment fees and certain direct origination costs are deferred, and the net amount amortized as an adjustment of the related loan’s yield. The Company is amortizing these amounts over the contractual lives of the related loans. Residential real estate loans are generally placed on nonaccrual when reaching 90 days past due or in process of foreclosure. All closed-end consumer loans 90 days or more past due and any equity line in the process of foreclosure are placed on nonaccrual status. Secured consumer loans are written down to realizable value and unsecured consumer loans are charged off upon reaching 120 or 180 days past due depending on the type of loan. Commercial real estate loans and commercial business loans and leases which are 90 days or more past due are generally placed on nonaccrual status, unless secured by sufficient cash or other assets immediately convertible to cash. When a loan has been placed on nonaccrual status, previously accrued and uncollected interest is reversed against interest on loans. A loan can be returned to accrual status when collectibility of principal is reasonably assured and the loan has performed for a period of time, generally six months. Cash receipts of interest income on impaired loans are credited to principal to the extent necessary to eliminate doubt as to the collectibility of the net carrying amount of the loan. Some or all of the cash receipts of interest income on impaired loans is recognized as interest income if the remaining net carrying amount of the loan is deemed to be fully collectible. When recognition of interest income on an impaired loan on a cash basis is appropriate, the amount of income that is recognized is limited to that which would have been accrued on the net carrying amount of the loan at the contractual interest rate. Any cash interest payments received in excess of the limit and not applied to reduce the net carrying amount of the loan are recorded as recoveries of charge-offs until the charge-offs are fully recovered.
ALLOWANCE FOR LOAN LOSSES	ALLOWANCE FOR LOAN LOSSES: The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectibility of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. General Component: The general component of the allowance for loan losses is based on historical loss experience adjusted for qualitative factors stratified by the following loan segments: one- to four-family residential real estate, home equity loans and lines of credit, commercial real estate, construction, and consumer. Management uses a rolling average of historical losses based on a time frame appropriate to capture relevant loss data for each loan segment. This historical loss factor is adjusted for the following qualitative factors: levels/trends in delinquencies; trends in volume and terms of loans; effects of changes in risk selection and underwriting standards and other changes in lending policies, procedures and practices; experience/ability/depth of lending management and staff; and national and local economic trends and conditions. There were no changes in the Company’s policies or methodology pertaining to the general component of the allowance for loan losses during the years ending December 31, 2015 and 2014. The qualitative factors are determined based on the various risk characteristics of each loan segment. Risk characteristics relevant to each portfolio segment are as follows: One- to four-family residential real estate: The Company generally does not originate loans with a loan-to-value ratio greater than 80% and does not grant subprime loans. Loans with loan-to-value ratios greater than 80% require private mortgage insurance. 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. Loans in this segment also include home equity loans and lines of credit. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Commercial real estate: Loans in this segment are primarily income-producing properties throughout Massachusetts. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy as evidenced by increased vacancy rates, which in turn, will have an effect on the credit quality in this segment. Loans in this segment also include loans secured by multifamily dwellings. Management periodically obtains rent rolls and continually monitors the cash flows of these loans. Construction loans: Loans in this segment primarily include speculative real estate development loans for which payment is derived from sale of the property. Credit risk is affected by cost overruns, time to sell at an adequate price, and market conditions. Consumer loans: Loans in this segment are generally secured and repayment is dependent on the credit quality of the individual borrower. Loans in this segment include auto loans and other consumer loans. Allocated Component: The allocated component relates to loans that are classified as impaired. Impairment is measured on a loan by loan basis for commercial real estate and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. An allowance is established when the discounted cash flows (or collateral value) of the impaired loan is lower than the carrying value of that loan. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and one- to four-family residential real estate loans for impairment disclosures, unless such loans are subject to a troubled debt restructuring agreement. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The Company periodically may agree to modify the contractual terms of loans. When a loan is modified and a concession is made to a borrower experiencing financial difficulty, the modification is considered a troubled debt restructuring (“TDR”). All TDRs are initially classified as impaired. Unallocated Component: An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating allocated and general reserves in the portfolio.
PREMISES AND EQUIPMENT	PREMISES AND EQUIPMENT: Land is carried at cost. Buildings and equipment are stated at cost, less accumulated depreciation and amortization. Cost and related allowances for depreciation and amortization of premises and equipment retired or otherwise disposed of are removed from the respective accounts with any gain or loss included in income or expense. Depreciation and amortization are calculated principally on the straight-line method over the estimated useful lives of the assets. Estimated lives are 15 to 40 years for buildings and 3 to 10 years for furniture and equipment.
OTHER REAL ESTATE OWNED AND IN-SUBSTANCE FORECLOSURES	OTHER REAL ESTATE OWNED AND IN-SUBSTANCE FORECLOSURES: Foreclosed real estate is primarily comprised of property acquired through a foreclosure proceeding or acceptance of a deed-in-lieu of foreclosure. Foreclosed real estate is initially recorded at fair value, less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less costs to sell. Revenues and expenses from operations and changes in the valuation allowance are included in expenses related to foreclosed real estate. The Company classifies commercial loans as in-substance repossessed or foreclosed if the company receives physical possession of the debtor’s assets regardless of whether formal foreclosure proceedings take place. An in-substance repossession or foreclosure occurs, and the Company is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan upon either; (1) obtaining legal title to the residential real estate property upon completion of a foreclosure; or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement.
BANK-OWNED LIFE INSURANCE	BANK-OWNED LIFE INSURANCE: The Company has purchased insurance policies on the lives of certain directors, executive officers and employees. Bank-owned life insurance policies are reflected on the consolidated balance sheets at cash surrender value. Changes in net cash surrender value of the policies, as well as insurance proceeds received, are reflected in non-interest income on the consolidated statements of income and are not subject to income taxes.
ADVERTISING	ADVERTISING: The Company directly expenses costs associated with advertising as they are incurred. Advertising expense for the years ended December 31, 2015 and 2014 amounted to $143,000 and $120,000, respectively.
INCOME TAXES	INCOME TAXES: The Company recognizes income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are established for the temporary differences between the accounting basis and the tax basis of the Company’s assets and liabilities at enacted tax rates expected to be in effect when the amounts related to such temporary differences are realized or settled.
EMPLOYEE STOCK OWNERSHIP PLAN	EMPLOYEE STOCK OWNERSHIP PLAN: Compensation expense for the Employee Stock Ownership Plan (“ESOP”) is recorded at an amount equal to the shares allocated by the ESOP multiplied by the average fair value of the shares during the period. The Company recognizes compensation expense based upon the Company’s estimate of the number of shares expected to be allocated by the ESOP. Unearned compensation applicable to the ESOP is reflected as a reduction of stockholders’ equity in the consolidated balance sheet. The difference between the average fair value and the cost of shares allocated by the ESOP is recorded as an adjustment to additional paid-in-capital.
EARNINGS PER SHARE (EPS)	EARNINGS PER SHARE (EPS): When presented, basic EPS is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. For the purposes of computing diluted EPS, the treasury stock method is used. Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. The calculation of basic and diluted EPS is presented below. There were no common stock equivalents in the twelve month period ending December 31, 2015. Year Ended Net income (In Thousands, except share data) $ 658 Basic Common Shares: Weighted average common shares outstanding 2,825,847 Weighted average unallocated ESOP shares (218,820 ) Basic and diluted weighted average shares outstanding 2,607,027 Basic earnings per share $ 0.25 Diluted earnings per share (1) $ 0.25 (1) As of and during the year ended December 31, 2015, there were no potentially dilutive securities or contracts to issue common stock. Because the formation of the Company was completed on October 22, 2014, earnings per share data is not meaningful for the year ended December 31, 2014 and is therefore not presented.
FAIR VALUES OF FINANCIAL INSTRUMENTS	FAIR VALUES OF FINANCIAL INSTRUMENTS: Accounting Standards Codification (ASC) 825, “Financial Instruments,” requires that the Company disclose the estimated fair value for its financial instruments. Fair value methods and assumptions used by the Company in estimating its fair value disclosures are as follows: Cash and cash equivalents: The carrying amounts reported in the balance sheets for cash and cash equivalents approximate those assets’ fair values. Securities: Fair values for securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. Loans held-for-sale: Fair values of loans held-for-sale are based on commitments on hand from investors or prevailing market prices. Loans receivable: For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. The fair values for other loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Accrued interest receivable: The carrying amount of accrued interest receivable approximates its fair value. Deposit liabilities: The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings and money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for fixed-rate certificate accounts are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on certificate accounts. Off-balance sheet instruments: The fair value of commitments to originate loans is estimated using the fees currently charged to enter similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments and the unadvanced portion of loans, fair value also considers the difference between current levels of interest rates and the committed rates.
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS: As an “emerging growth company,” as defined in Title 1 of Jumpstart Our Business Startups (JOBS) Act, the Company has elected to use the extended transition period to delay adoption of new or reissued accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. Accordingly, the consolidated financial statements may not be comparable to the financial statements of public companies that comply with such new or revised accounting standards. As of December 31, 2015, there is no significant difference in the comparability of the financial statements as a result of this extended transition period. In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-05, “Intangibles – Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” This ASU provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. Under the extended transition period for an emerging growth company, this ASU is effective for annual periods beginning after December 15, 2015, and interim periods in annual periods beginning after December 31, 2016. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In May 2015, the FASB issued ASU 2015-07: “Fair Value Measurement (Topic 820) – Disclosure for Investments in Certain Entities That Calculate Net Asset Value per Share (or its Equivalent).” The objective of this update is to address the diversity in practice related to how certain investments measured at net asset value with redemption dates in the future are categorized within the fair value hierarchy. The amendments in this update remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The amendments also remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. Under the extended transition period for an emerging growth company, the amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments in this ASU address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments and makes targeted improvements to GAAP as follows: 1. Require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. However, the entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same manner. 2. Simplify the impairment assessment of equity investments without determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. 3. Eliminate the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. 4. Require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 5. Require an entity to present separately in other comprehensive income the portion of the total change in fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. 6. Require separate presentation of financial assets and financial liabilities by measurement category and form of financial assets (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. 7. Clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. Under the extended transition period for an emerging growth company, the amendments in this Update are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption of item 5 above is permitted as of the fiscal years beginning after December 31, 2019, or interim periods for which financial statements have not been issued. Early adoption of all other amendments in this ASU is not permitted. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” This ASU was issued to increase transparency and comparability among organizations by requiring reporting entities to recognize all leases, including operating, as lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. Under the extended transition period for an emerging growth company, the amendments in this ASU are effective for fiscal years beginning after December 31, 2019, and interim periods within fiscal years being after December 15, 2020. The Company anticipates that the adoption of this ASU will not have a material impact on its consolidated financial statements.
