Organization	NOTE 1 – Organization PB Bancorp, Inc. (the “Company”) is a Maryland corporation incorporated in 2015 to be the successor to PSB Holdings, Inc. upon completion of the second-step mutual-to-stock conversion (the “Conversion”) of Putnam Bancorp, MHC (the “MHC”), the top tier mutual holding company of PSB Holdings, Inc. PSB Holdings, Inc. was the former mid-tier holding company for Putnam Bank (the “Bank”). Prior to completion of the Conversion, approximately 57% of the shares of common stock of PSB Holdings, Inc. were owned by the MHC. In conjunction with the Conversion, the MHC and PSB Holdings, Inc. merged into the Company and the Company became PSB Holdings, Inc.’s successor. The Conversion was completed on January 7, 2016. The Company raised gross proceeds of $33.7 million by selling a total of 4,215,387 shares of common stock at $8.00 per share in the second step offering. Also, an additional 317,287 shares were purchased by the Bank’s Employee Stock Ownership Plan with the proceeds of a loan from the Company. Concurrent with the completion of the stock offering, each share of PSB Holdings, Inc. stock owned by public stockholders (stockholders other than the MHC) was exchanged for 1.1907 shares of Company common stock. A total of 3,347,728 shares of Company common stock were issued in the exchange. The Conversion was accounted for as a capital raising transaction by entities under common control. The historical financial results of the MHC were immaterial to the results of the Company and therefore the net assets of the MHC were reflected as an increase to stockholders’ equity.

Critical Accounting Policies

Accounting Policies [Abstract]
Critical Accounting Policies	Note 4 - Critical Accounting Policies Critical accounting policies are those that involve significant judgments and assumptions by management that have, or could have, a material impact on our income or the carrying value of our assets. Our critical accounting policies are those related to the allowance for loan losses, realizability of deferred income taxes, valuation of goodwill and the impairment of securities. Allowance for Loan Losses The allowance for loan losses is evaluated on a quarterly basis by management. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of general, specific and unallocated components, as further described below. General component The general component of the allowance for loan losses is based on historical loss experience adjusted for qualitative factors stratified by the following loan segments: residential real estate, commercial real estate, construction, commercial and consumer/other. 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; concentrations; changes in lending policies and procedures; experience/ability/depth of lending management and staff; loan rating migration; the effect of other external factors; changes in the value of underlying collateral; changes in the loan review system and national and local economic trends and conditions. During the quarter ended December 31, 2016, the Company changed its calculation of historical losses from a two-year rolling average to a five-year rolling average. The change was made to enable the Company to include more meaningful and relevant loss data over a time period indicative of the risk in the Company’s current loan portfolio. The change in calculation did not have a material effect on our allowance for loan losses. There were no other changes in the Company’s policies or methodology pertaining to the general component of the allowance for loan losses through March 31, 2018. The qualitative factors are determined based on the various risk characteristics of each loan segment. Risk characteristics relevant to each portfolio segment are as follows: Residential real estate - The Company does not originate loans with a loan-to-value ratio greater than 100% and does not originate subprime loans. Loans originated with a loan-to-value ratio greater than 80% generally 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. 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 New England. 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. Management obtains rent rolls annually and continually monitors the cash flows of these loans. Construction – Loans in this segment include speculative real estate development loans for which payment is derived from sale of the property. Credit risk is affected by the accuracy of estimated costs to complete the project, cost overruns, time to sell at an adequate price, and market conditions. Commercial – Loans in this segment are made to businesses and are generally secured by assets of the business. Repayment is expected from the cash flows of the business. A weakened economy, and resultant decreased consumer spending, will have an effect on the credit quality in this segment. Consumer/other - Loans in this segment are generally unsecured and repayment is dependent on the credit quality of the individual borrower. Specific component The specific component relates to loans that are classified as impaired. Impairment is measured on a loan by loan basis 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 or foreclosure is probable. 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/other and residential real estate loans for impairment disclosures, unless such loans are non-accrual or subject to a troubled debt restructuring (“TDR”) 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 TDR. All TDRs are 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 specific and general reserves in the portfolio. Goodwill The first step (“Step 1”) is used to identify potential impairment, and involves comparing the reporting unit’s (the consolidated Company) estimated fair value to its carrying amount, including goodwill. If the estimated fair value of the reporting unit exceeds its carrying amount, goodwill is not deemed to be impaired. Should the carrying amount of the reporting unit exceed its estimated fair value, an indicator of impairment is deemed to exist and a second step is performed to measure the amount of such impairment, if any. The second step (“Step 2”) involves calculating the implied fair value of goodwill. The implied fair value of goodwill is determined in a manner similar to how the amount of goodwill is determined in a business combination (i.e. by measuring the excess of the estimated fair value, as determined in Step 1, over the aggregate estimated fair values of the individual assets, liabilities, and identifiable intangibles as of the impairment testing date). If the implied fair value of goodwill exceeds the carrying amount of goodwill assigned to the reporting unit, no impairment exists. If the carrying amount of goodwill exceeds the implied fair value of the goodwill, an impairment loss is recorded in an amount equal to such excess. An impairment loss cannot exceed the carrying amount of goodwill, and the loss (write-down) establishes a new carrying amount for the goodwill. Subsequent reversal of goodwill impairment losses is not permitted. Application of the goodwill impairment test requires significant judgments including estimation of future cash flows, which are dependent on internal forecasts, estimation of the long-term rate of growth, the period over which cash flows will occur, and determination of our cost of capital. Changes in these estimates and assumptions could materially affect the determination of fair value and/or conclusions related to goodwill impairment. See Note 3 – Recent Accounting Pronouncements for future changes to the accounting treatment of goodwill. Other-Than-Temporary Impairment of Securities. OTTI is required to be recognized if (1) the Company intends to sell the security; (2) it is “more likely than not” that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) for debt securities, the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. Marketable equity securities are evaluated for OTTI based on the severity and duration of the impairment and, if deemed to be other than temporary, the declines in fair value are reflected in earnings as realized losses. For impaired debt securities that the Company intends to sell, or more likely than not will be required to sell, the full amount of the depreciation is recognized as OTTI through earnings. For all other impaired debt securities, credit-related OTTI is recognized through earnings and non-credit related OTTI is recognized in other comprehensive income/loss, net of applicable taxes. Income Taxes. On December 22, 2017, the President signed into law the Tax Cuts and Jobs Act (the “Act”). The Act includes a number of changes in existing tax law impacting businesses including, among other things, a permanent reduction in the corporate income tax rate from 34% to 21%, effective on January 1, 2018. As a result of this rate reduction, the Company revalued its net deferred tax asset as of December 22, 2017 resulting in a reduction in the value of the net deferred tax asset of $211,000, which was recorded as additional tax expense in the Company’s consolidated statements for the three months ended December 31, 2017. Included in the additional tax expense is $47,000 related to net unrealized losses on securities available-for-sale. The accounting treatment effectively stranded $47,000 of deferred tax items in accumulated other comprehensive income. The Company has developed a reasonable estimate of the other provisions of the Act in determining the current year income tax provision. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“AOCI”) Management has discussed the development and selection of these critical accounting policies with the Audit Committee.

Earnings Per Share (EPS)	NOTE 5 – Earnings Per Share (EPS) Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. The rights to dividends on unvested options/awards are non-forfeitable, therefore the unvested awards/options are considered outstanding in the computation of basic earnings per share. Diluted earnings per share reflect 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 Company. For purposes of computing diluted EPS, the treasury stock method is used. The following information was used in the computation of EPS on both a basic and diluted basis for the three and nine months ended March 31, 2018 and 2017: Three months ended March 31, Nine months ended March 31, 2018 2017 2018 2017 Net income $ 965,000 $ 635,000 $ 2,340,000 $ 1,743,000 Weighted average common shares applicable to basic EPS 7,295,257 7,411,018 7,341,827 7,431,341 Effect of dilutive potential common shares - 2,765 - 1,156 Weighted average common shares applicable to diluted EPS 7,295,257 7,413,783 7,341,827 7,432,497 Earnings per share: Basic $ 0.13 $ 0.09 $ 0.32 $ 0.23 Diluted $ 0.13 $ 0.09 $ 0.32 $ 0.23 For the three and nine months ended March 31, 2018, options to purchase 392,330 shares were outstanding but not included in the computation of earnings per share because they were anti-dilutive.

Gains and losses on the sales of securities are recorded on the trade date and are determined using the specific identification method. There were $1,000 in other-than-temporary impairment charges on available-for-sale securities realized in income during the nine months ended March 31, 2018. There were no other-than-temporary impairment charges on available-for-sale securities during the three and nine months ended March 31, 2017. The write-downs for the nine months ended March 31, 2018 included total other-than-temporary impairment losses on non-agency mortgage-back securities of $2,000, net of $1,000 recognized in other comprehensive loss, before taxes.

Management evaluates securities for OTTI at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. At March 31, 2018, there were 94 individual investment securities with aggregate depreciation of 2.6% from the Company’s amortized cost basis. Management has the intent and ability to hold these securities until cost recovery occurs and considers these declines to be temporary. The unrealized losses on the Company’s investment in U.S. Government-sponsored agency bonds and U.S. government-guaranteed and government-sponsored residential mortgage-backed securities were primarily caused by interest rate fluctuations. These investments are guaranteed or sponsored by the U.S. government or an agency thereof. Accordingly, it is expected that the securities would not be settled at a price less than the par value of the investment. Because the decline in market value is attributable to changes in interest rates and not to credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider these investments to be other-than-temporarily impaired at March 31, 2018. The Company’s unrealized losses on investments in corporate bonds and other securities relate to investments in companies within the financial services sector. As of March 31, 2018, the Company had five investments in corporate single-issuer trust preferred securities (TRUPs) with a total book value of $6.0 million and total fair value of $5.6 million, all of which were classified as available-for-sale. The single-issuer trust preferred investments are evaluated for other-than-temporary impairment by performing a present value of cash flows calculation each quarter. None of the issuers have deferred interest payments or announced the intention to defer interest payments. The Company believes the decline in fair value is related to the spread over three-month LIBOR, on which the quarterly interest payments are based, as the spread over LIBOR being received is significantly lower than current market spreads. Management concluded the impairment of these investments was considered temporary and asserts that the Company does not have the intent to sell these investments and that it is more likely than not it will not have to sell the investments before recovery of their cost bases which may be at maturity. At March 31, 2018, there was one state and political subdivision security that had an unrealized loss of 3.6% from the Company’s amortized cost basis. The unrealized loss was primarily caused by interest rate fluctuations. This security is guaranteed by a school district located in Texas. Because the decline in market value is attributable to changes in interest rates and not to credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity, the Company does not consider this investment to be other-than-temporarily impaired at March 31, 2018. For the nine months ended March 31, 2018, securities with other-than-temporary impairment losses recognized in earnings consisted of non-agency mortgage-backed securities. For these debt securities, the Company estimated the portion of loss attributable to credit loss using a discounted cash flow model. Significant inputs included the estimated cash flows of the underlying loans based on key assumptions, such as default rate, loss severity and prepayment rate. Assumptions can vary widely from security to security, and are influenced by such factors as loan interest rate, geographical location of the borrower, borrower characteristics and collateral type. The present value of the expected cash flows was compared to the Company’s amortized cost basis to determine the credit-related impairment loss. Based on the expected cash flows derived from the model, the Company expects to recover the remaining unrealized losses on these securities. The following table represents a roll-forward of the amount of credit losses on debt securities for which a portion of other-than-temporary impairment was recognized in other comprehensive loss: Nine months ended March 31, 2018 2017 (in thousands) Balance at beginning of period $ 15,982 $ 15,982 Additional credit losses on securities for which an other-than-temporary impairment charge was previously recorded 1 - Balance at end of period $ 15,983 $ 15,982

Loans	NOTE 7 – Loans The following table sets forth the composition of our loan portfolio at March 31, 2018 and June 30, 2017: March 31, June 30, 2018 2017 (in thousands) Real Estate: Residential (1) $ 240,369 $ 225,745 Commercial 95,687 71,558 Residential construction 1,573 1,000 Commercial 12,267 12,123 Consumer and other 849 829 Total loans 350,745 311,255 Net deferred loan costs 1,431 1,317 Allowance for loan losses (2,939 ) (2,780 ) Loans, net $ 349,237 $ 309,792 (1) Residential real estate loans include one-to four-family mortgage loans, second mortgage loans, and home equity lines of credit. Credit Quality Information The Company utilizes a nine grade internal loan rating system as follows: Loans rated 1 - 5 are considered “pass” rated loans with low to average risk. Loans rated 6 are considered “special mention.” These loans are starting to show signs of potential weakness and are being closely monitored by management. Loans rated 7 are considered “substandard.” Generally, a loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. There is a distinct possibility that the Company will sustain some loss if the weakness is not corrected. Loans rated 8 are considered “doubtful.” Loans classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable. Loans rated 9 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, construction and commercial loans. Annually, the Company engages an independent third-party to review a significant portion of loans within these segments. Management uses the results of these reviews as part of its annual review process. Credit quality for residential real estate and consumer/other loans is determined by monitoring loan payment history and ongoing communications with the borrower. The following table presents the Company’s loan classes by internally assigned grades at March 31, 2018 and June 30, 2017: Residential Commercial Residential Consumer Real Estate Real Estate Construction Commercial and other Total (in thousands) March 31, 2018 Grade: Pass $ 236,092 $ 92,548 $ 1,573 $ 12,267 $ 848 $ 343,328 Special Mention 377 1,074 - - - 1,451 Substandard 3,900 2,065 - - 1 5,966 Doubtful - - - - - - Loss - - - - - - Total $ 240,369 $ 95,687 $ 1,573 $ 12,267 $ 849 $ 350,745 June 30, 2017 Grade: Pass $ 221,514 $ 68,675 $ 1,000 $ 12,123 $ 827 $ 304,139 Special Mention 394 715 - - - 1,109 Substandard 3,837 2,168 - - 2 6,007 Doubtful - - - - - - Loss - - - - - - Total $ 225,745 $ 71,558 $ 1,000 $ 12,123 $ 829 $ 311,255 There were no material modifications deemed to be troubled debt restructures for the nine months ended March 31, 2018 and 2017.

Many of our commercial relationships are secured by development loans, in particular condominiums which have experienced a significant reduction in demand. The Bank reviews the strength of the guarantors; requires face to face discussions and offers restructuring suggestions that provide the borrowers with short term relief and exit strategies. The Bank obtains a current appraisal on all real estate secured loans that are 180 days or more past due if the appraisal on file is older than one year. If the determination is made that there is the potential for collateral shortfall, an allocated reserve will be assigned to the loan for the expected deficiency. It is the policy of the Bank to charge off or write down loans or other assets when, in the opinion of the Credit Committee and Loan Review, the ultimate amount recoverable is less than the carrying value, or the collection of the amount is expected to be unduly prolonged. The level of non-performing assets is expected to fluctuate in response to changing economic and market conditions, and the relative sizes of the respective loan portfolios, along with management’s degree of success in resolving problem assets.

Stock-Based Incentive Plan	NOTE 10 – Stock-Based Incentive Plan At the annual meeting of stockholders on February 17, 2017, stockholders of the Company approved the PB Bancorp, Inc. 2017 Stock-Based Incentive Plan (the “Incentive Plan”). Under the Incentive Plan, the Company may grant up to 453,267 stock options and 181,306 shares of restricted stock to its employees, officers and directors for an aggregate amount of up to 634,573 shares of the Company’s common stock for issuance upon the grant or exercise of awards. Both incentive stock options and non-statutory stock options may be granted under the Incentive Plan. On March 30, 2017, the Company awarded 392,330 options to purchase the Company’s common stock and 147,750 shares of restricted stock. Stock option awards were granted with an exercise price equal to the market price of the Company’s stock at the date of grant ($10.15) with a maximum term of ten years. Both stock option and restricted stock awards granted to date vest at 20% per year beginning on the first anniversary of the date of the grant. Stock options are considered common stock equivalents for the purpose of computing earnings per share on a diluted basis. Restricted stock awards have non-forfeitable dividend rights, and are considered participating securities outstanding for the purpose of computing basic earnings per share. The Company has recorded share-based compensation expense related to outstanding stock option and restricted stock awards based upon the fair value at the date of grant over the vesting period of such awards on a straight-line basis. The fair value of each restricted stock allocation, based on the market price at the date of grant, is recorded to unearned stock awards. Compensation expense related to unearned restricted shares is amortized to compensation and benefits expense over the vesting period of the restricted stock awards, adjusted by actual forfeitures. The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option pricing method which includes several assumptions such as volatility, expected dividends, expected term and risk-free rate for each stock option award. The Company recorded share-based compensation expense in connection with the stock option and restricted stock awards for the three months ended March 31, 2018 of $112,000 and for the nine months ended March 31, 2018 of $336,000.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASURMENTS	NOTE 12 – FAIR VALUE MEASUREMENTS The Company groups its assets measured at fair value in three levels, based on the markets in which the assets are traded and the reliability of the assumptions used to determine fair value as follows: Level 1 – Valuations for assets traded in active exchange markets, such as the New York Stock Exchange. Valuations are obtained from readily available pricing sources for market transactions involving identical assets. Level 2 – Valuations for assets traded in less active dealer or broker markets. Valuations are obtained from third party pricing services for identical or comparable assets. Level 3 – Valuations for assets that are derived from other methodologies, including option pricing models, discounted cash flow models and similar techniques, and 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. 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 assets carried at fair value for March 31, 2018. The Company’s mortgage-backed securities and other debt securities available-for-sale are generally classified within Level 2 of the fair value hierarchy. For these securities, we obtain fair value measurements from independent pricing services, which are not adjusted by management. 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. Level 3 assets consisted of available-for-sale auction-rate trust preferred securities (ARPs). All dividends are current. The Company has the ability and intent to hold these securities for the time necessary to collect the expected cash flows. The Company’s impaired loans and other real estate owned are reported at the fair value of the underlying collateral if repayment is expected solely from the collateral. Collateral values are estimated using Level 3 inputs based upon appraisals of similar properties obtained from a third party and adjusted by management as needed. The Company did not have any transfers of assets between levels of the fair value hierarchy during the three and nine months ended March 31, 2018. The following summarizes assets measured at fair value on a recurring basis at March 31, 2018 and June 30, 2017: Total Fair Value Level 1 Level 2 Level 3 (in thousands) At March 31, 2018 Securities available-for-sale: U.S. government and government-sponsored securities $ 4,410 $ - $ 4,410 $ - Corporate bonds and other securities 5,616 - 5,616 - U.S. Government-sponsored and guaranteed mortgage-backed securities 26,871 - 26,871 - Non-agency mortgage-backed securities 3,438 - 3,438 - Equity securities 10,000 - - 10,000 Total $ 50,335 $ - $ 40,335 $ 10,000 At June 30, 2017 Securities available-for-sale: U.S. government and government-sponsored securities $ 4,766 $ - $ 4,766 $ - Corporate bonds and other securities 5,578 - 5,578 - U.S. Government-sponsored and guaranteed mortgage-backed securities 35,915 - 35,915 - Non-agency mortgage-backed securities 3,891 - 3,891 - Equity securities 10,000 - - 10,000 Total $ 60,150 $ - $ 50,150 $ 10,000 There were no changes in level 3 assets measured at fair value for the nine months ended March 31, 2018 and 2017.

Fair value estimates are made at a specific point in time, based on relevant market information and information about the asset. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular asset. Because a market may not readily exist for a significant portion of the Company’s asset, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. There were no liabilities measured at fair value on a recurring or non-recurring basis at March 31, 2018 or June 30, 2017. The following methods and assumptions were used by the Company in estimating fair value disclosures of its financial instruments: Cash and Cash Equivalents. Investment Securities Held-to-Maturity and FHLBB Stock. Loans. The fair values of residential, commercial real estate, residential construction, commercial and consumer and other loans were estimated by discounting the anticipated cash flows from the respective portfolios. Estimates of the timing and amount of these cash flows considered factors such as future loan prepayments. The discount rates reflected current market rates for loans with similar terms to borrowers of similar credit quality. The fair value of home equity lines of credit was based on the outstanding loan balances. Fair values for non-performing loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable. Deposits and Mortgagors’ Escrow. Federal Home Loan Bank Advances. Securities Sold Under Agreements to Repurchase. Accrued Interest. Off-Balance Sheet Instruments. Summary of Fair Values of Financial Instruments. The following table presents the carrying amount and estimated fair values of the Company’s financial instruments, all of which are held or issued for purposes other than trading, as of March 31, 2018 and June 30, 2017: March 31, 2018 Carrying Fair Value Hierarchy Total Fair Amount Level 1 Level 2 Level 3 Value (in thousands) Financial assets: Cash and cash equivalents $ 9,513 $ 9,513 $ - $ - $ 9,513 Securities available-for-sale 50,335 - 40,335 10,000 50,335 Securities held-to-maturity 87,724 - 86,956 - 86,956 Federal Home Loan Bank stock 4,486 - - 4,486 4,486 Loans, net 349,237 - - 344,599 344,599 Accrued interest receivable 1,297 - - 1,297 1,297 Financial liabilities: Deposits 370,959 - - 372,194 372,194 Mortgagors' escrow accounts 1,754 - - 1,754 1,754 Federal Home Loan Bank advances 70,712 - 69,524 - 69,524 Securities sold under agreements to repurchase 755 - 755 - 755 Accrued interest payable 120 - - 120 120 June 30, 2017 Carrying Fair Value Hierarchy Total Fair Amount Level 1 Level 2 Level 3 Value (in thousands) Financial assets: Cash and cash equivalents $ 10,173 $ 10,173 $ - $ - $ 10,173 Securities available-for-sale 60,150 - 50,150 10,000 60,150 Securities held-to-maturity 110,022 - 110,823 - 110,823 Federal Home Loan Bank stock 4,353 - - 4,353 4,353 Loans, net 309,792 - - 310,015 310,015 Accrued interest receivable 1,258 - - 1,258 1,258 Financial liabilities: Deposits 365,761 - - 367,233 367,233 Mortgagors' escrow accounts 2,850 - - 2,850 2,850 Federal Home Loan Bank advances 67,000 - 68,079 - 68,079 Securities sold under agreements to repurchase 1,582 - 1,582 - 1,582 Accrued interest payable 115 - - 115 115

New Accounting Pronouncements and Changes In Accounting Principles [Abstract]
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is evaluated on a quarterly basis by management. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of general, specific and unallocated components, as further described below. General component The general component of the allowance for loan losses is based on historical loss experience adjusted for qualitative factors stratified by the following loan segments: residential real estate, commercial real estate, construction, commercial and consumer/other. 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; concentrations; changes in lending policies and procedures; experience/ability/depth of lending management and staff; loan rating migration; the effect of other external factors; changes in the value of underlying collateral; changes in the loan review system and national and local economic trends and conditions. During the quarter ended December 31, 2016, the Company changed its calculation of historical losses from a two-year rolling average to a five-year rolling average. The change was made to enable the Company to include more meaningful and relevant loss data over a time period indicative of the risk in the Company’s current loan portfolio. The change in calculation did not have a material effect on our allowance for loan losses. There were no other changes in the Company’s policies or methodology pertaining to the general component of the allowance for loan losses through March 31, 2018. The qualitative factors are determined based on the various risk characteristics of each loan segment. Risk characteristics relevant to each portfolio segment are as follows: Residential real estate - The Company does not originate loans with a loan-to-value ratio greater than 100% and does not originate subprime loans. Loans originated with a loan-to-value ratio greater than 80% generally 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. 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 New England. 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. Management obtains rent rolls annually and continually monitors the cash flows of these loans. Construction – Loans in this segment include speculative real estate development loans for which payment is derived from sale of the property. Credit risk is affected by the accuracy of estimated costs to complete the project, cost overruns, time to sell at an adequate price, and market conditions. Commercial – Loans in this segment are made to businesses and are generally secured by assets of the business. Repayment is expected from the cash flows of the business. A weakened economy, and resultant decreased consumer spending, will have an effect on the credit quality in this segment. Consumer/other - Loans in this segment are generally unsecured and repayment is dependent on the credit quality of the individual borrower. Specific component The specific component relates to loans that are classified as impaired. Impairment is measured on a loan by loan basis 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 or foreclosure is probable. 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/other and residential real estate loans for impairment disclosures, unless such loans are non-accrual or subject to a troubled debt restructuring (“TDR”) 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 TDR. All TDRs are 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 specific and general reserves in the portfolio.
Goodwill	Goodwill The first step (“Step 1”) is used to identify potential impairment, and involves comparing the reporting unit’s (the consolidated Company) estimated fair value to its carrying amount, including goodwill. If the estimated fair value of the reporting unit exceeds its carrying amount, goodwill is not deemed to be impaired. Should the carrying amount of the reporting unit exceed its estimated fair value, an indicator of impairment is deemed to exist and a second step is performed to measure the amount of such impairment, if any. The second step (“Step 2”) involves calculating the implied fair value of goodwill. The implied fair value of goodwill is determined in a manner similar to how the amount of goodwill is determined in a business combination (i.e. by measuring the excess of the estimated fair value, as determined in Step 1, over the aggregate estimated fair values of the individual assets, liabilities, and identifiable intangibles as of the impairment testing date). If the implied fair value of goodwill exceeds the carrying amount of goodwill assigned to the reporting unit, no impairment exists. If the carrying amount of goodwill exceeds the implied fair value of the goodwill, an impairment loss is recorded in an amount equal to such excess. An impairment loss cannot exceed the carrying amount of goodwill, and the loss (write-down) establishes a new carrying amount for the goodwill. Subsequent reversal of goodwill impairment losses is not permitted. Application of the goodwill impairment test requires significant judgments including estimation of future cash flows, which are dependent on internal forecasts, estimation of the long-term rate of growth, the period over which cash flows will occur, and determination of our cost of capital. Changes in these estimates and assumptions could materially affect the determination of fair value and/or conclusions related to goodwill impairment. See Note 3 – Recent Accounting Pronouncements for future changes to the accounting treatment of goodwill.
Other-Than-Temporary Impairment of Securities	Other-Than-Temporary Impairment of Securities. OTTI is required to be recognized if (1) the Company intends to sell the security; (2) it is “more likely than not” that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) for debt securities, the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. Marketable equity securities are evaluated for OTTI based on the severity and duration of the impairment and, if deemed to be other than temporary, the declines in fair value are reflected in earnings as realized losses. For impaired debt securities that the Company intends to sell, or more likely than not will be required to sell, the full amount of the depreciation is recognized as OTTI through earnings. For all other impaired debt securities, credit-related OTTI is recognized through earnings and non-credit related OTTI is recognized in other comprehensive income/loss, net of applicable taxes.
Income Taxes	Income Taxes. On December 22, 2017, the President signed into law the Tax Cuts and Jobs Act (the “Act”). The Act includes a number of changes in existing tax law impacting businesses including, among other things, a permanent reduction in the corporate income tax rate from 34% to 21%, effective on January 1, 2018. As a result of this rate reduction, the Company revalued its net deferred tax asset as of December 22, 2017 resulting in a reduction in the value of the net deferred tax asset of $211,000, which was recorded as additional tax expense in the Company’s consolidated statements for the three months ended December 31, 2017. Included in the additional tax expense is $47,000 related to net unrealized losses on securities available-for-sale. The accounting treatment effectively stranded $47,000 of deferred tax items in accumulated other comprehensive income. The Company has developed a reasonable estimate of the other provisions of the Act in determining the current year income tax provision. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“AOCI”) Management has discussed the development and selection of these critical accounting policies with the Audit Committee.
