Basis of Financial Statement Presentation	1. BASIS OF FINANCIAL STATEMENT PRESENTATION The unaudited consolidated financial statements include the accounts of Randolph Bancorp, Inc. (“Bancorp”) and its wholly-owned subsidiary, Envision Bank (the “Bank”, together with Bancorp, the “Company”). The Bank has subsidiaries involved in owning investment securities and foreclosed real estate properties and a subsidiary which provides loan closing services. All intercompany accounts and transactions have been eliminated in consolidation. When necessary, certain amounts in prior year financial statements have been reclassified to conform to the current year’s presentation. These unaudited financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial reporting and with the instructions to Form 10-Q and Article 10 of Regulation S-X issued by the Securities and Exchange Commission (“SEC”). Accordingly, the accompanying interim financial statements do not include all information required under GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation of the financial statements, primarily consisting of normal recurring adjustments, have been included. The operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results to be expected for the year ending December 31, 2020 or any other interim period.

Risks And Uncertainties [Abstract]
Global Pandemic Affecting Randolph Bancorp, Inc. In 2020	3 . GLOBAL PANDEMIC AFFECTING RANDOLPH BANCORP, INC. IN 2020 On March 13, 2020, the United States Government declared a national emergency in response to the coronavirus (“COVID-19”) outbreak. This outbreak has caused, among other things, widespread shutdowns of businesses and volatile markets and has severely disrupted normal economic activity in the region the Company serves as well as across the nation. The following summarizes the more significant financial repercussions of this national emergency for the Company. Credit Quality and Allowance for Loan Losses The Company established a $511,000 allowance for loan losses during the first six months of 2020 directly related to the initial estimate, based on available information, of probable incurred losses resulting from the impact of the COVID-19 pandemic. As the Company acquires additional information on overall economic prospects together with further assessments of the impact on individual borrowers, the loss estimated will be revised as needed, and these revisions could be material. The Company’s approach to estimating the impact of this pandemic on credit quality is presented in Note 6 – “Loans and Allowance for Loan Losses.” Disaster Response Plan Costs The Company implemented its disaster response plans when the national emergency was declared and a stay at home order was issued in the Commonwealth of Massachusetts. To operate in this mode the Company incurred expenses for, among other things, compensation for front-line and quarantined employees, buying equipment for a remote workforce, cleaning of office and branch buildings, and communications with customers regarding the status of the Company’s operations. These plan costs amounted to $207,000 through the first six months of 2020. Loan Payment Deferral and Paycheck Protection Program In response to the pandemic’s effect on our customers, the Company implemented a series of measures through the date of this report, including participation in the Small Business Administration’s (“SBA”) Paycheck Protection Program (the “PPP”) and granting payment deferrals for residential mortgage, home equity and certain commercial borrowers who were current in their payments. As of June 30, 2020, the Company has funded $15.1 million of loans as part of the PPP. These loans are included with commercial and industrial loans, are pledged to the Federal Reserve’s Paycheck Protection Program Liquidity Facility and have no direct effect on the Company’s capital ratios. T In accordance with interagency guidance issued in March 2020, these short-term deferrals are not considered troubled debt restructurings, provided the loan was current as of the date the deferral program was implemented. The Company has agreed to loan payment deferrals on commercial loans totaling $28.8 million, residential real estate loans in portfolio totaling $17.2 million and residential real estate loans serviced for others totaling $56.8 million as of June 30, 2020. The commercial loan payment deferrals are concentrated in the hotel, restaurant and retail service industries. The qualifying residential real estate and commercial loan borrowers were required to contact the Company to receive loan payment deferrals. The payment deferral programs were applied prospectively from the respective dates of the events and did not change the delinquency status of the loans as of such dates. Accordingly, if all payments were current at the date of the event, the loan will not be reported as past due during the deferral period. Furthermore, for loans subject to the deferral programs on which payments were past due prior to the event, the delinquency status of such loans was frozen to the status that existed at the date of the event until the end of the deferral period.

Accumulated Other Comprehensive Income (Loss)	4 . ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income (loss). Although certain changes in assets and liabilities are reported as a separate component of stockholders’ equity, such items, along with net income (loss), are components of comprehensive income (loss). The components of accumulated other comprehensive income (loss), included in total stockholders’ equity, are as follows: June 30, December 31, 2020 2019 (In thousands) Securities available for sale: Net unrealized gain $ 1,888 $ 167 Tax effect (313 ) (313 ) Net-of-tax amount 1,575 (146 ) Supplemental retirement plan Unrecognized net actuarial loss (634 ) (652 ) Unrecognized net prior service credit 287 311 (347 ) (341 ) Tax effect (47 ) (47 ) Net-of-tax amount (394 ) (388 ) Accumulated other comprehensive income (loss) $ 1,181 $ (534 )

The amortized cost and fair value of debt securities by contractual maturity at June 30, 2020 are presented below. Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

The unrealized losses at June 30, 2020 were due to securities price fluctuations since the time they were purchased. The Company currently does not believe it is probable that it will be unable to collect all amounts due according to the contractual terms of these investments. Therefore, it is expected that the securities would not be settled at a price less than the par value of the investment. Because the Company does not intend to sell any debt securities and it is more likely than not that the Company will not be required to sell any debt securities before recovery of its amortized cost basis, it does not consider these investments to be other-than-temporarily impaired at June 30, 2020.

This pandemic has severely disrupted normal economic activity in the communities the Company serves along with the rest of the nation. It is impossible to know the full extent of the impact of the COVID-19 pandemic and the continued effects it may have on the Company’s operations. Management has determined a separate qualitative element of the allowance to represent the estimate of probable incurred losses associated with the impact of the pandemic events on the Company’s loan portfolios. This estimate is judgmental and subject to changes as conditions evolve. This qualitative element of the allowance was determined based on the impact the pandemic has had on current employment levels, economic activity in the Company’s geographic regions, and the time it could take for the affected regions to return to a more normalized operating environment. The following is a summary of past due and non-accrual loans at June 30, 2020 and December 31, 2019: 30 - 59 Days Past Due 60 - 89 Days Past Due 90 Days or More Past Due Total Past Due Non-accrual Loans (In thousands) June 30, 2020 Residential one-to-four family $ — $ 268 $ 582 $ 850 $ 2,661 Home equity loans and lines of credit — 22 — 22 586 Commercial real estate 4,776 2,022 — 6,798 — Construction — — — — — Commercial and industrial — — — — — Consumer 124 88 — 212 — Total $ 4,900 $ 2,400 $ 582 $ 7,882 $ 3,247 December 31, 2019 Residential one-to-four family $ 215 $ 587 $ — $ 802 $ 2,922 Home equity loans and lines of credit 188 244 — 432 336 Commercial real estate — — — — — Construction — — — — — Commercial and industrial — — — — — Consumer 76 11 — 87 — Total $ 479 $ 842 $ — $ 1,321 $ 3,258 The following is a summary of impaired loans at June 30, 2020 and December 31, 2019: Recorded Investment Unpaid Principal Balance Related Allowance (In thousands) June 30, 2020 Impaired loans without a valuation allowance: Residential one-to-four family $ 3,084 $ 3,084 Home equity loans and lines of credit 781 781 Commercial real estate 43 43 Total 3,908 3,908 Impaired loans with a valuation allowance: Residential one-to-four family 966 966 $ 85 966 966 85 Total impaired loans $ 4,874 $ 4,874 $ 85 December 31, 2019 Impaired loans without a valuation allowance: Residential one-to-four family $ 3,322 $ 3,322 Home equity loans and lines of credit 407 407 Commercial real estate 46 46 Total 3,775 3,775 Impaired loans with a valuation allowance: Residential one-to-four family 2,318 2,318 $ 116 Total 2,318 2,318 116 Total impaired loans $ 6,093 $ 6,093 $ 116 Additional information pertaining to impaired loans follows: Average Interest Cash Basis Recorded Income Interest Investment Recognized Recognized (In thousands) Three Months Ended June 30, 2020 Residential one-to-four family $ 4,941 $ 75 $ 41 Home equity loans and lines of credit 404 1 — Total $ 5,345 $ 76 $ 41 Three Months Ended June 30, 2019 Residential one-to-four family $ 5,498 $ 49 $ 19 Home equity loans and lines of credit 337 4 4 Commercial real estate 187 1 — Consumer 49 — — Total $ 6,071 $ 54 $ 23 Six Months Ended June 30, 2020 Residential one-to-four family $ 5,138 $ 133 $ 70 Home equity loans and lines of credit 405 1 — Total $ 5,543 $ 134 $ 70 Six Months Ended June 30, 2019 Residential one-to-four family $ 5,630 $ 126 $ 51 Home equity loans and lines of credit 437 10 10 Commercial real estate 187 2 — Consumer 49 1 — Total $ 6,303 $ 139 $ 61 Troubled Debt Restructurings The Company periodically grants concessions to borrowers experiencing financial difficulties. The Company’s troubled debt restructurings consist primarily of interest rate concessions for periods of three months to thirty years for residential real estate loans, and for periods up to one year for commercial real estate loans. At June 30, 2020, the Company had sixteen residential real estate loans, one consumer loan and one commercial real estate loan aggregating $2,910,000, $43,000 and $43,000, respectively, which were subject to troubled debt restructuring agreements. At June 30, 2019, the Company had sixteen residential real estate loans and one commercial real estate loan aggregating $3,260,000 and $49,000, respectively, which were subject to troubled debt restructuring agreements. As of June 30, 2020 and 2019, $2,997,000 and $3,309,000, respectively, in troubled debt restructurings were performing in accordance with the terms of the modified loan agreements. Included in such amounts are $1,530,000 and $649,000, respectively, that are being accounted for as non-accrual loans as they have not yet had six consecutive months of performance. For the six months ended June 30, 2020, the Company did not enter into any loan modifications meeting the criteria of a troubled debt restructuring. For the the Company entered into two loan modifications meeting the criteria of a troubled debt restructuring in which a loan term concession was granted to a borrower. Management performs a discounted cash flow calculation to determine the amount of valuation reserve required on each of the troubled debt restructurings. Any reserve required is recorded as part of the allowance for loan losses. During the three and six months ended June 30, 2020 and 2019 , there were no material changes to the allowance for loan losses as a result of loan modifications made which were considered a troubled debt restructuring. No additional funds are committed to be advanced in connection with trouble debt restructurings. During the three and six months ended June 30, 2020 and 2019, there were no troubled debt restructurings that defaulted (over 30 days past due) within twelve months of the restructure date. Credit Quality Information The Company utilizes an eight-grade internal loan rating system for commercial real estate, construction and commercial and industrial loans, as follows: Loans rated 1 – 3B are considered “pass” rated loans with low to average risk. Loans rated 4 are considered “special mention.” These loans are starting to show signs of potential weakness and are being closely monitored by management. Loans rated 5 are considered “substandard” and are 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 are considered “doubtful” and 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 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 and industrial 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. The following table presents the Company’s loans by risk rating at the dates indicated: June 30, 2020 December 31, 2019 Commercial Real Construction Commercial and Industrial Commercial Real Construction Commercial and Industrial (In thousands) Loans rated 1 - 3B (Pass rated) $ 120,212 $ 35,181 $ 21,813 $ 121,703 $ 35,485 $ 8,134 Loans rated 4 10,263 — 503 3,702 — 206 Loans rated 5 4,275 — 624 — — 753 $ 134,750 $ 35,181 $ 22,940 $ 125,405 $ 35,485 $ 9,093 Residential mortgages, home equity loans and lines of credit, and consumer loans are monitored for credit quality based primarily on their payment status. When one of these loans becomes more than 90 days delinquent, it is assigned an internal loan rating. At June 30, 2020, $2,546,000 and $350,000 in residential mortgages and home equity loans were rated as substandard, and $1,310,000 in residential mortgages and $334,000 in home equity loans were rated as special mention. At December 31, 2019, $2,925,000 in residential mortgages were rated as substandard, and $1,293,000 in residential mortgages and $336,000 in home equity loans were rated as special mention.

Loan Servicing	7 . LOAN SERVICING Mortgage loans serviced for others are not included in the accompanying unaudited consolidated balance sheets. The unpaid principal balances of residential mortgage loans serviced for others were $1.34 billion and $1.05 billion at June 30, 2020 and December 31, 2019, respectively. The following table summarizes the activity relating to mortgage servicing rights (“MSRs”) for the six months ended June 30, 2020 and 2019 (in thousands): June 30, 2020 June 30, 2019 Mortgage servicing rights: Balance at beginning of year $ 9,484 $ 7,794 Additions through originations 3,562 1,100 Amortization (955 ) (572 ) Balance at end of period $ 12,091 $ 8,322 Valuation allowance: Balance at beginning of year $ 928 $ 8 Provision 3,069 113 Balance at end of period $ 3,997 $ 121 Amortized cost, net $ 8,094 $ 8,201 Fair value $ 8,294 $ 8,356 During the six months ended June 30, 2020 and 2019, the Company increased the valuation allowance for its MSRs by $3,069,000 and $113,000, respectively. Such adjustments to the valuation allowance were due primarily to changes in fair value caused by the impact of changes in interest rates on expected loan prepayments.

Income Taxes	8 . INCOME TAXES Income tax expense for the three months ended June 30, 2020 and 2019 represents a state tax expense of $594,000 and $119,000, respectively. The state tax expense is based on the projected state tax rate for the year. During the six months ended June 30, 2020 and 2019, the Company recorded a current state tax expense of $605,000 and $83,000, respectively. Since 2014, the Company has maintained a valuation allowance for all of its deferred tax assets based on a determination that it was more likely than not that such assets would not be realized. This determination was based on the Company’s net operating loss carryforward position, its current period operating results exclusive of non-recurring items and its expectations for the upcoming year. After incurring losses in four of the five previous years, the Company had net income of $3.4 million in 2019. In performing its assessment of the need for a valuation allowance as of December 31, 2019, management concluded that the improvement in operating results, while significant, would need to be sustained for an additional period to provide sufficient evidence that realizability of deferred tax assets was more likely than not to occur. As a result, the 100% valuation allowance for deferred tax assets was maintained. The tax valuation allowance at June 30, 2020 totaled $1.2 million.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
On-Balance Sheet Derivative Instruments and Hedging Activities	9 . ON-BALANCE SHEET DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Derivative Loan Commitments Mortgage loan interest rate lock commitments qualify as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. The Company enters into commitments to fund residential mortgage loans at specified rates and times in the future, with the intention that these loans will subsequently be sold either in the secondary market, to large aggregators of loans or to other financial institutions. Outstanding derivative loan commitments expose the Company to the risk that the price of the loans arising from exercise of the loan commitment might decline from inception of the rate lock to funding of the loan due to an increase in mortgage interest rates. If interest rates increase, the value of these loan commitments decreases. Conversely, if interest rates decrease, the value of these loan commitments increases. The notional amount of derivative loan commitments was $329,348,000 and $89,925,000 at June 30, 2020 and December 31, 2019, respectively. The fair value of such commitments at June 30, 2020 and December 31, 2019 was $9,182,000 and $1,472,000, respectively, and is included in other assets in the consolidated balance sheets. Forward Loan Sale Commitments The Company utilizes both “mandatory delivery” and “best efforts” forward loan sale commitments and To Be Announced (“TBA”) securities to mitigate the risk of potential decreases in the value of loans that would result from the exercise of the derivative loan commitments as well as for loans held for sale. With a “mandatory delivery” contract, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. If the Company fails to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, it is obligated to pay a “pair-off” fee, based on then-current market prices, to the investor to compensate the investor for the shortfall. With a “best efforts” contract, the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor if the loan to the underlying borrower closes. Generally, the price the investor will pay the seller for an individual loan is specified prior to the loan being funded (e.g., on the same day the lender commits to lend funds to a potential borrower). The Company expects that these forward loan sale commitments and TBA securities will experience changes in fair value that serve to offset the change in fair value of loans held for sale and derivative loan commitments the degree to which depends on the notional amount of such sale commitments. The notional amount of forward loan sale commitments and TBA securities was $301,706,000 and $85,401,000 at June 30, 2020 and December 31, 2019, respectively. The fair value of such commitments consisted of liabilities of $1,547,000 and $140,000 at June 30, 2020 and December 31, 2019, respectively, included in other liabilities in the consolidated balance sheets and assets of $7,000 and $11,000 are included in other assets in the consolidated balance sheets as of June 30, 2020 and December 31, 2019, respectively.

Employee Stock Ownership Plan	10 . The Company maintains an Employee Stock Ownership Plan (“ESOP”), which is a tax-qualified retirement plan providing eligible employees the opportunity to own Bancorp stock. Bancorp made a loan to the ESOP for the purchase of 469,498 shares of its common stock at $10.00 per share in connection with its initial public offering in July 2016. The loan is payable annually over 25 years with interest at the prime rate to be reset each January 1. The loan is secured by the shares which have not yet been allocated to participants. Loan payments are funded by cash contributions from the Bank. Such contributions are allocated to eligible participants based on their compensation, subject to federal tax limits. Shares are committed to be released on a monthly basis and allocated as of December 31 of each year. The number of shares to be allocated annually is 18,780 through the year 2040. For the three and six months ended June 30, 2020, the Company recognized compensation expense for the ESOP of $44,000 and $112,000, respectively, while for the three and six months ended June 30, 2019, the Company recognized compensation expense for the ESOP of $68,000 and $138,000, respectively. The fair value of the 384,988 unallocated ESOP shares at June 30, 2020 was $3,869,000.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	1 2 . EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share represents net income (loss) divided by the weighted average of common shares outstanding during the period. Unvested restricted shares of common stock having dividend rights are treated as “participating securities” and, accordingly, are considered outstanding in computing basic earnings (loss) per share. Unallocated ESOP shares are not considered to be outstanding for purposes of computing earnings per share. None of the Company’s outstanding stock options were included in the computation of diluted earnings (loss) per share for the three and six months ended June 30, 2020 and 2019 as their impact would have been anti-dilutive. The following table sets forth the calculation of the average number of shares outstanding used to calculate the basic and diluted earnings (loss) per share for the periods indicated: Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 Average number of common shares outstanding 5,479,826 5,871,321 5,497,383 5,880,309 Less: Average unallocated ESOP shares (387,336 ) (406,116 ) (389,683 ) (408,463 ) 5,092,490 5,465,205 5,107,700 5,471,846

Both incentive stock options and nonqualified stock options may be granted under the Equity Plan with 586,872 shares initially reserved for options. Any options forfeited because vesting requirements are not met or expired will become available for re-issuance under the Equity Plan. The exercise price of each option equals the market price of the Company’s stock on the date of the grant and the maximum term of each option is 10 years. The total number of shares initially reserved for restricted stock is 234,749. Options and awards generally vest ratably over three to five years. The fair value of shares awarded is based on the market price at the date of grant. Stock Options The fair value of each option grant is estimated on the date of the grant using the Black-Scholes option-pricing model with the following assumptions: • Volatility is based on peer group volatility because the Company does not have a sufficient trading history. • Expected life represents the period of time that the option is expected to be outstanding, taking into account the contractual term, and the vesting period. • Expected dividend yield is based on the Company's history and expectation of dividend payouts. • The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for a period equivalent to the expected life of the option. During the six months ended June 30, 2020 and 2019, the Company made the following grants of options to purchase shares of common stock and used the following assumptions in measuring the fair value of such grants: 2020 2019 Options granted 123,118 57,252 Vesting period (years) 3-5 1-5 Expiration period (years) 10 10 Expected volatility 26.71 % 29.87 % Expected life (years) 6.2 6.5 Expected dividend yield — — Risk free interest rate 0.45% - 1.10% 2.37% - 2.61% Option fair value $2.69 - $4.32 $2.99 - $5.83 A summary of stock option activity for the six months ended June 30, 2020 is presented in the table below: Options Stock Option Grants Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Balance at January 1, 2020 360,207 $ 14.82 8.01 $ — Granted 123,118 13.25 Forfeited (11,543 ) 15.24 Expired (91,614 ) 14.67 Balance at June 30, 2020 380,168 $ 14.34 8.24 $ 56,030 Exercisable at June 30, 2020 101,993 $ 14.92 7.53 $ — Unrecognized compensation cost (inclusive of directors' options) $ 934,863 Weighted average remaining recognition period (years) 2.72 For the six months ended June 30, 2020 and 2019, stock-based compensation expense applicable to stock options was $428,000 and $192,000, respectively. For the three months ended June 30, 2020 and 2019, stock-based compensation expense applicable to stock options was $99,000 and $101,000, respectively. Included in expense for the six months ended June 30, 2020 is $233,000 attributable to accelerated vesting of options upon the retirement of two executive officers. Restricted Stock Shares issued may be either authorized but unissued shares or reacquired shares held by the Company. Any shares forfeited because vesting requirements are not met will become available for reissuance under the Equity Plan. The fair market value of shares awarded, based on the market price at the date of grant, is amortized over the applicable vesting period. Restricted stock awarded to date has been at no cost to the awardee. The following table presents the activity in restricted stock awards under the Equity Plan for the six months ended June 30, 2020: Restricted Stock Awards Weighted Average Grant Price Restricted stock awards at January 1, 2020 125,861 $ 14.76 Granted 15,000 8.78 Vested (41,380 ) 14.72 Forfeited (7,251 ) 14.85 Restricted stock awards at March 31, 2020 92,230 $ 13.80 Unrecognized compensation cost $ 1,008,533 Weighted average remaining recognition period (years) 2.90 For the six months ended June 30, 2020 and 2019 stock-based compensation expense applicable to restricted stock was $700,000 and $266,000, respectively. For the three months ended June 30, 2020 and 2019, stock-based compensation expense applicable to restricted stock was $98,000 and $141,000, respectively. Included in expense for the six months ended June 30, 2020 is $450,000 attributable to accelerated vesting of restricted stock awards upon the retirement of two executive officers.

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	1 4 . Determination of fair value The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various assets and liabilities. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the asset or liability. The following methods and assumptions were used by the Company in estimating fair value disclosures: Securities Loans held for sale Fair values are based on commitments in effect from investors or prevailing market prices and include the servicing value of the loans. Loans Mortgage servicing rights On-balance-sheet derivatives - Fair values of forward loan sale commitments and derivative loan commitments are based on fair values of the underlying mortgage loans using current market prices for similar assets in the secondary market. For derivative loan commitments, fair values also consider the value of servicing, costs to be incurred to close loans and the probability of such commitments being exercised. Off-balance sheet credit-related instruments Assets and liabilities recorded at fair value on a recurring basis Assets and liabilities recorded at fair value on a recurring basis are summarized below. Total Level 1 Level 2 Level 3 Fair (In thousands) June 30, 2020 Assets: Securities available for sale $ — $ 54,462 $ — $ 54,462 Portfolio loans (fair value option) — 17,062 — 17,062 Loans held for sale (fair value option) — 61,673 — 61,673 Derivative loan commitments — 9,182 — 9,182 Forward loan sale commitments — 7 — 7 Liabilities: Forward loan sale commitments, including TBAs — 1,547 — 1,547 December 31, 2019 Assets: Securities available for sale $ — $ 57,503 $ — $ 57,503 Portfolio loans (fair value option) — 9,826 — 9,826 Loans held for sale (fair value option) — 62,792 — 62,792 Derivative loan commitments — 1,472 — 1,472 Forward loan sale commitments — 11 — 11 Liabilities: Forward loan sale commitments, including TBAs — 140 — 140 There were no transfers between levels for assets and liabilities recorded at fair value on a recurring basis during the six months ended June 30, 2020 and 2019. Assets recorded at fair value on a non-recurring basis The Company may also be required, from time to time, to record certain other assets at fair value on a non-recurring basis in accordance with GAAP. These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets. The following table summarizes the fair value hierarchy used to determine each adjustment and the carrying value of the related assets as of June 30, 2020 and December 31, 2019. Period Ended June 30, 2020 June 30, 2020 Level 1 Level 2 Level 3 Total Gains (Losses) (In thousands) Collateral dependent impaired loans $ — $ — $ 4,419 $ — Mortgage servicing rights — — 8,094 (3,069 ) Foreclosed real estate — — 132 — $ — $ — $ 12,645 $ (3,069 ) December 31, 2019 Level 1 Level 2 Level 3 (In thousands) Collateral dependent impaired loans $ — $ — $ 2,250 Mortgage servicing rights — — 8,556 $ — $ — $ 10,806 The Company recorded an increase in the valuation allowance for its MSRs of $3,069,000 during the six months ended June 30, 2020 L osses applicable to write-downs of impaired loans and foreclosed real estate are based on the appraised value of the underlying collateral less estimated costs to sell. The losses on impaired loans are not recorded directly as an adjustment to current earnings, but rather as a component in determining the allowance for loan losses. The losses on foreclosed real estate represent adjustments in valuation recorded during the time period indicated and not for losses incurred on sales. Appraised values are typically based on a blend of (a) an income approach using observable cash flows to measure fair value, and (b) a market approach using observable market comparisons. These appraised values may be discounted based on management’s historical knowledge, expertise or changes in market conditions from time of valuation. There were no liabilities measured at fair value on a non-recurring basis at June 30, 2020 and December 31, 2019. Summary of fair values of financial instruments The estimated fair values, and related carrying amounts, of the Company’s financial instruments are presented below. Certain financial instruments and all non-financial instruments are exempt from disclosure requirements. Accordingly, the aggregate fair value amounts presented herein do not represent the underlying fair value of the Company. This table excludes financial instruments for which the carrying amount approximates fair value. Financial assets for which the fair value approximates carrying value include cash and cash equivalents, and accrued interest receivable. Financial liabilities for which the fair value approximates carrying value include mortgagors’ escrow accounts and accrued interest payable.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	1 5 . COMMITMENTS AND CONTINGENCIES Loan commitments The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit. These instruments involve, to varying degrees, elements of market, credit and interest rate risk which are not recognized in the unaudited consolidated financial statements. The Company’s exposure to credit loss is represented by the contractual amount of these commitments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. The following financial instruments were outstanding, at the dates indicated, whose contract amounts represent credit risk: June 30, 2020 December 31, 2019 (In thousands) Commitments to originate loans $ 354,127 $ 117,086 Unused lines and letters of credit 59,015 52,721 Unadvanced funds on construction loans 8,430 11,029 Overdraft lines of credit 7,984 8,178 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The commitments for lines of credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The majority of these financial instruments are collateralized by real estate. Other contingencies The Company is not currently a party to any pending legal proceedings that it believes would have a material adverse effect on its financial condition, results of operations or cash flows.
