SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Consolidation The unaudited interim Consolidated Financial Statements of HarborOne Bancorp, Inc. presented herein have been prepared pursuant to the rules of the SEC for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by GAAP. In the opinion of management, all adjustments and disclosures considered necessary for the fair presentation of the accompanying Consolidated Financial Statements have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements for the years ended December 31, 2022 and 2021 and notes thereto included in the Company’s Annual Report on Form 10-K. The unaudited interim Consolidated Financial Statements include the accounts of the Company; the Company’s subsidiaries, Legion Parkway Company LLC (a security corporation) and HarborOne Bank; and the Bank’s wholly-owned subsidiaries, which consist of HarborOne Mortgage, LLC, HarborOne Security Company, Inc. and a passive investment corporation The passive investment corporation maintains and manages certain assets of the Bank. The security company was established for the purpose of buying, holding and selling securities on its own behalf. All significant intercompany balances and transactions have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year financial statement presentation. These changes and reclassifications did not impact previously reported net income or comprehensive income. Nature of Operations The Company provides a variety of financial services to individuals and businesses through its 30 full-service branches in Massachusetts and Rhode Island, and a commercial lending office in each of Boston, Massachusetts and Providence, Rhode Island. HarborOne Mortgage maintains offices in Florida, Maine, Massachusetts, New Hampshire, New Jersey and Rhode Island and originates loans in five additional states. The Company’s primary deposit products are checking, money market, savings, and term certificate of deposit accounts, while its primary lending products are commercial real estate, commercial, residential mortgages, home equity, and consumer loans. The Company also originates, sells and services residential mortgage loans through HarborOne Mortgage. Risks and Uncertainties During the first quarter of 2023, the banking industry experienced significant volatility with multiple high-profile bank failures and industry-wide concerns related to liquidity, deposit outflows, unrealized securities losses and eroding consumer confidence in the banking system. In response to these events, the Treasury, the Federal Reserve, and the FDIC jointly announced the BTFP on March 12, 2023. This program aims to enhance liquidity by allowing institutions to pledge certain securities at the par value of the securities, and at a borrowing rate of ten basis points over the one-year overnight index swap rate. The BTFP is available to eligible U.S. federally insured depository institutions, with advances having a term of up to one year and no prepayment penalties. Macroeconomic trends are mixed as uncertainty remains about the economy and banking industry. Reliance on secondary funding sources could increase the Company’s overall cost of funds and thereby reduce net income. While the Company believes its current sources of liquidity are adequate to fund operations, there is no guarantee they will suffice to meet future liquidity demands. This may necessitate slowing or discontinuing loan growth, capital expenditures, or other investments, or liquidating assets. Additionally, the Company could experience adverse effects on its business, financial condition, results of operations and cash flows if there is severe or prolonged inflation, a recession, further escalation of the current geopolitical situation, or sustained supply chain disruptions. While asset quality continues to point to economic recovery, the Company’s customers could experience similar adverse effects from these uncertainties that would impair their ability to fulfill their financial obligations to the Company resulting in deteriorating credit quality and loan charge-offs. Summary of Significant Accounting Policies and Recently Adopted Accounting Standards Updates Significant accounting policies in effect and disclosed within the Company’s most recent audited Consolidated Financial Statements as of December 31, 2022 remain substantially unchanged. In March 2022, the FASB issued ASU 2022-02, “Financial Instruments – Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures” ASU 2022-02 also requires that public business entities disclose current-period gross charge-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, “Financial Instruments—Credit Losses—Measured at Amortized Cost.” The Company adopted ASU 2022-02 effective January 1, 2023 on a modified retrospective basis. The adoption of ASU 2022-02 did not have a material impact on the Company’s Consolidated Financial Statements.

U.S. government and government-sponsored enterprise obligations and corporate bonds are callable at the discretion of the issuer. U.S. government and government-sponsored enterprise obligations and corporate bonds with a total fair value of $54.3 million have a final maturity of four to nine years and a call feature of one month to four years . At June 30, 2023, there were no holdings of securities of any one issuer, other than the U.S. government and its agencies, in an amount greater than 10% of shareholder equity. There were no sales or calls of securities in the three and six months ended June 30, 2023 and 2022, respectively. Information pertaining to securities with gross unrealized losses at June 30, 2023 and December 31, 2022 aggregated by investment category and length of time that individual securities have been in a continuous loss position follows: Less Than Twelve Months Twelve Months and Over Gross Gross Unrealized Fair Unrealized Fair Losses Value Losses Value (in thousands) June 30, 2023: Securities available for sale U.S. government and government-sponsored enterprise obligations $ — $ — $ 7,958 $ 39,185 U.S. government agency and government-sponsored residential mortgage-backed securities 67 1,547 58,025 246,286 U.S. government-sponsored collateralized mortgage obligations — — 112 2,126 SBA asset-backed securities — — 172 2,032 Corporate bonds — — 198 802 $ 67 $ 1,547 $ 66,465 $ 290,431 Securities held to maturity U.S. government and government-sponsored enterprise obligations $ 175 $ 4,825 505 9,495 SBA asset-backed securities 154 4,685 — — $ 329 $ 9,510 $ 505 $ 9,495 December 31, 2022: Securities available for sale U.S. government and government-sponsored enterprise obligations $ 249 $ 4,751 $ 8,400 $ 33,743 U.S. government agency and government-sponsored residential mortgage-backed securities 3,620 35,214 55,529 221,566 U.S. government-sponsored collateralized mortgage obligations 113 2,499 — — SBA asset-backed securities 190 2,495 — — Corporate bonds 154 846 — — $ 4,326 $ 45,805 $ 63,929 $ 255,309 Securities held to maturity U.S. government and government-sponsored enterprise obligations $ 597 $ 14,403 $ — $ — SBA asset-backed securities 78 4,871 — — $ 675 $ 19,274 $ — $ — Management assesses the decline in fair value of investment securities on a regular basis. Unrealized losses on debt securities may occur from current market conditions, increases in interest rates since the time of purchase, a structural change in an investment, volatility of earnings of a specific issuer, or deterioration in credit quality of the issuer. Management evaluates both qualitative and quantitative factors to assess whether an impairment exists. As of June 30, 2023, the Company’s security portfolio consisted of 132 debt securities, 131 of which were in an unrealized loss position. The unrealized losses are primarily related to the Company’s debt securities that were issued by U.S. government-sponsored entities and agencies. The Company does not believe that the debt securities that were in an unrealized loss position as of June 30, 2023 represent a credit loss impairment. As of June 30, 2023, and December 31, 2022, the gross unrealized loss positions were primarily related to mortgage-backed securities and other obligations issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government and have a long history of zero credit loss. Total gross unrealized losses were primarily attributable to changes in interest rates relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. Management reviewed the collectability of the corporate bonds taking into consideration such factors as the financial condition of the issuers, reported regulatory capital ratios of the issuers, credit ratings, including ratings in effect as of the reporting period date as well as credit rating changes between the reporting period date and the filing date of this report, and other information. Management believes the unrealized losses on the corporate bonds are primarily attributable to changes in the investment spreads and interest rates and not changes in the credit quality of the issuers of the corporate bonds. Management expects to recover the entire amortized cost basis of the available-for-sale debt securities with an unrealized loss. Furthermore, the Company does not intend to sell these securities, and it is likely that the Company will not be required to sell these securities, before recovery of their cost basis, which may be at maturity. Therefore, no ACL was recorded at June 30, 2023. As of June 30, 2023, the held-to-maturity securities were U.S. government sponsored agency obligations. These securities are guaranteed by the government sponsored agency with a long history of no credit losses and Management has determined these securities to have a zero loss expectation and therefore does not estimate an allowance for credit losses on these securities.

Changes in fair value of mortgage loans held for sale accounted for under the fair value option election amounted to an increase of $28,000 and $35,000 in the three and six months ended June 30, 2023, respectively, to $371,000, compared to an increase of $522,000 in the three months ended June 30, 2022 and a decrease of $791,000 in the six months ended June 30, 2022. These amounts are offset in earnings by the changes in fair value of forward sale commitments. The changes in fair value are reported as a component of gain on sale of mortgage loans in the Unaudited Consolidated Statements of Income. At June 30, 2023 and December 31, 2022, there were no loans held for sale that were greater than 90 days past due.

As of June 30, 2023 and December 31, 2022, the commercial and industrial loans includes $389,000 and $2.1 million, respectively, of SBA PPP loans and $52,000 and $65,000, respectively, of deferred fees on the PPP loans. PPP loans are fully guaranteed by the U.S. government. The Company has transferred a portion of its originated commercial loans to participating lenders. The amounts transferred have been accounted for as sales and are therefore not included in the Company’s accompanying unaudited interim Consolidated Balance Sheets. The Company and participating lenders share ratably in cash flows and any gains or losses that may result from a borrower’s lack of compliance with contractual terms of the loan. The Company continues to service the loans on behalf of the participating lenders and, as such, collects cash payments from the borrowers, remits payments to participating lenders, and disburses required escrow funds to relevant parties. At June 30, 2023 and December 31, 2022, the Company was servicing commercial loans for participants in the aggregate amount of $386.5 million and $366.4 million, respectively.

As of December 31, 2022, the carrying value of individually analyzed loans amounted to $23.8 million, with a related allowance of $203,000, and $15.9 million were considered collateral-dependent. For collateral-dependent loans where management has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and repayment of the loan is to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the loan as of the measurement date.

Loan Modifications to Borrowers Experiencing Financial Difficulty Effective January 1, 2023, ASU 2022-02 Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures was adopted. The Bank will modify the contractual terms of loans to a borrower experiencing financial difficulties as a way to mitigate loss and comply with regulations regarding bankruptcy and discharge situations. Modifications to borrowers experiencing financial difficulty may include interest rate reductions, principal or interest forgiveness, forbearances, term extensions, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral. There were no material loan modifications based on borrower financial difficulty during the three and six months ended June 30, 2023 and 2022. There were no loans to borrowers experiencing financial difficulty that had a payment default during the three and six months ended June 30, 2023 and 2022 and were modified in the twelve months prior to that default. Default is determined at 90 or more days past due, upon charge-off, or upon foreclosure. Modified loans in default are individually evaluated for the allowance for credit losses or if the modified loan is deemed uncollectible, the loan, or a portion of the loan, is written off, and the allowance for credit losses is adjusted accordingly. Credit Quality Indicators Commercial The Company uses a ten-grade internal loan rating system for commercial real estate, commercial construction and commercial loans, as follows: Loans rated 1 – 6 are considered “pass”-rated loans with low to average risk. Loans rated 7 are considered “special mention.” These loans are starting to show signs of potential weakness and are being closely monitored by management. Loans rated 8 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 9 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 10 are considered “uncollectible” (loss), and of such little value that their continuance as loans is not warranted. Loans not rated consist primarily of certain smaller balance commercial real estate and commercial loans that are managed by exception. On an annual basis, or more often if needed, the Company formally reviews on a risk-adjusted basis, the ratings on all commercial real estate, construction and commercial loans. Semi-annually, the Company engages an independent third party to review a significant portion of loans within these segments.

MORTGAGE LOAN SERVICING
MORTGAGE LOAN SERVICING	5. MORTGAGE LOAN SERVICING The Company sells residential mortgages to government-sponsored entities and other parties. The Company retains no beneficial interests in these loans, but it may retain the servicing rights of the loans sold. Mortgage loans serviced for others are not included in the accompanying unaudited interim Consolidated Balance Sheets. The risks inherent in MSRs relate primarily to changes in prepayments that generally result from shifts in mortgage interest rates. The unpaid principal balance of mortgage loans serviced for others was $3.60 billion and $3.62 billion as of June 30, 2023 and December 31, 2022. The Company accounts for MSRs at fair value. The Company obtains and reviews valuations from an independent third party to determine the fair value of MSRs. Key assumptions used in the estimation of fair value include prepayment speeds, discount rates, and default rates June 30, December 31, 2023 2022 Prepayment speed 7.20 % 7.10 % Discount rate 9.90 9.81 Default rate 1.41 1.63 The following summarizes changes to MSRs for the three and six months ended June 30, 2023 and 2022: Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 (in thousands) Balance, beginning of period $ 47,080 $ 45,043 $ 48,138 $ 38,268 Additions 660 1,225 1,294 2,715 Changes in fair value due to: Reductions from loans paid off during the period (479) (771) (850) (1,604) Changes in valuation inputs or assumptions 915 1,633 (406) 7,751 Balance, end of period $ 48,176 $ 47,130 $ 48,176 $ 47,130 Contractually specified servicing fees, net of subservicing expense, included in other mortgage banking income amounted to $1.9 million and $3.9 million for the three and six months ended June 30, 2023 and $2.1 million and $4.0 million for the three and six months ended June 30, 2022.

GOODWILL AND OTHER INTANGIBLE ASSETS
GOODWILL AND OTHER INTANGIBLE ASSETS	6. GOODWILL AND OTHER INTANGIBLE ASSETS There were no changes in the carrying value of goodwill for the periods ended June 30, 2023 and December 31, 2022. The Bank and HarborOne Mortgage are identified as reporting units for purposes of goodwill impairment testing. At June 30, 2023 and December 31, 2022, the carrying value of the Bank’s goodwill was $59.0 million as of both dates, and the carrying value of HarborOne Mortgage’s goodwill was $10.8 million as of both dates. Goodwill is tested for impairment annually on October 31 or on an interim basis if an event triggering impairment may have occurred. As of June 30, 2023, the Company assessed whether there were additional events or changes in circumstances since its annual goodwill impairment test that would indicate that it was more likely than not that the fair value of the reporting unit was less than the reporting unit’s carrying amounts that would require an interim impairment assessment after October 31, 2022. The Company determined there had been no such indicators, therefore, no interim goodwill impairment assessment as of June 30, 2023 was performed. The process of evaluating fair value is highly subjective and requires significant judgment and estimates. The goodwill at the Bank and HarborOne Mortgage is at risk of future impairment if projected operating results are not met or other inputs into the fair value measurement model change. If concerns persist in the banking sector as a result of the recent bank failures, management may determine a triggering event has occurred, which would cause us to perform an interim impairment test. Interim impairment tests at the Bank or HarborOne Mortgage may result in an impairment charge being recorded in the period. Other intangible assets were $1.9 million and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. The Company determined that there was no triggering event that warranted an interim impairment test at June 30, 2023.

Municipal deposits are generally required to be fully insured. The Company provided supplemental insurance for municipal deposits through DIF, a reciprocal deposit program or letters of credit offered by the FHLB. DIF was exited February 24, 2023 and will generally provide coverage until February 24, 2024 on deposits that existed at the exit date. The Company has established a relationship to participate in a reciprocal deposit program with other financial institutions. The reciprocal deposit program provides access to FDIC-insured deposit products in aggregate amounts exceeding the current limits for depositors. At June 30, 2023 and December 31, 2022, total reciprocal deposits were $149.2 million and $28.6 million, respectively, consisting of non-certificate accounts.

The carrying value of the loans pledged as collateral for these borrowings totaled $1.83 billion at June 30, 2023 and $1.71 billion at December 31, 2022. As of June 30, 2023, the Company had $583.7 million of available borrowing capacity with the FHLB. The Company also has additional borrowing capacity under a $25.0 million unsecured federal funds line with a correspondent bank and a secured line of credit with the FRBB, secured by 69% of the carrying value of commercial loans with principal balances amounting to $99.7 million and $100.2 million at June 30, 2023 and December 31, 2022, respectively. No amounts were outstanding under either line at June 30, 2023 or December 31, 2022. On March 12, 2023, the Federal Reserve announced the creation of the BTFP. The BTFP offers loans of up to one year to banks, savings associations, credit unions, and other eligible depository institutions pledging U.S. Treasury securities, agency debt and mortgage-backed securities, and other qualifying assets as collateral. These assets are valued at par for purposes of the collateral pledge under the BTFP. The Company has $366.8 million in borrowing capacity under this program, and no amounts were outstanding at June 30, 2023. On August 30, 2018, the Company issued $35.0 million in fixed-to-floating rate subordinated notes due 2028 in a private placement to institutional accredited investors. The Notes bear interest at annual fixed rate of 5.625% until September 1, 2023, at which time the interest rate resets quarterly to an interest rate per annum equal to the three–month CME Term SOFR plus applicable spread adjustment plus 278 basis points. Interest is payable semi-annually on March 1 and September 1 each year through September 1, 2023 and quarterly thereafter. The Notes can be redeemed partially or in whole, prior to the maturity date beginning September 1, 2023 and on any scheduled interest payment date thereafter, at par. The Notes are carried on the Consolidated Balance Sheets net of unamortized issuance costs of $652,000 and $715,000 at June 30, 2023 and December 31, 2022, respectively.

These financial instruments include commitments to extend credit and advance funds on various lines of credit. Those commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the accompanying unaudited interim 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 as it does for on-balance sheet instruments. The following off-balance sheet financial instruments were outstanding at June 30, 2023 and December 31, 2022. The contract amounts represent credit risk.

Commitments to grant loans generally have fixed expiration dates or other termination clauses and may require payment of a fee. The commitments for unadvanced funds on construction loans and home equity and revolving 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 credit-worthiness on a case-by-case basis. Commitments to grant loans, and unadvanced construction loans and home equity lines of credit are collateralized by real estate, while revolving lines of credit are unsecured.

DERIVATIVES

DERIVATIVES	Jun. 30, 2023
DERIVATIVES
DERIVATIVES	10. DERIVATIVES The Company’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally to manage the Company’s interest rate risk. Additionally, the Company enters into interest rate derivatives to accommodate the business requirements of its customers. All derivatives are recognized as either assets or liabilities on the balance sheet and are measured at fair value. The accounting for changes in the fair value of a derivative instrument depends upon whether or not it qualifies as a hedge for accounting purposes, and further, by the type of hedging relationship. Derivatives Designated as Hedging Instruments Fair Value Hedge As of June 30, 2023, the Company had two interest rate swap agreements with a notional amount of $100.0 million that were designated as a fair value hedge of fixed rate residential mortgages. The hedges were determined to be effective during the three months ended June 30, 2023, and the Company expects the hedges to remain effective during the remaining terms of the swaps. The following amounts were recorded on the Consolidated Balance Sheets related to cumulative basis adjustment for fair value hedges as of the dates indicated: Cumulative Amount of Fair Value Hedging Adjustment Included in the Line Item in the Consolidated Balance Sheets Carrying Amount of the Hedged Carrying Amount of the Hedged in Which the Hedged Item is Included Assets Assets June 30, June 30, June 30, June 30, 2023 2022 2023 2022 (in thousands) Loans held for investment (1) $ 99,556 $ — $ (444) $ — Total $ 99,556 $ — $ (444) $ — (1) Cashflow Hedge As of June 30, 2023, the Company had one interest rate swap agreement with a notional amount of $100.0 million that was designated as a cashflow hedge of brokered deposits. The interest rate swap agreement has an average maturity of 1.78 years, the current weighted average fixed rate paid is 0.671% , the weighted average 3-month LIBOR swap receive rate is 5.157% , and the fair value is $7.6 million. The Company expects approximately $4.7 million related to the cashflow hedge to be reclassified to interest expense, from other comprehensive income, in the next twelve months. Derivatives Not Designated as Hedging Instruments Derivative Loan Commitments- Mortgage loan 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 times in the future, with the intention that these loans will subsequently be sold in the secondary market. A mortgage loan commitment binds the Company to lend funds to a potential borrower at a specified interest rate and within a specified period of time, generally up to 60 days after inception of the rate lock. Outstanding derivative loan commitments expose the Company to the risk that the price of the loans arising from exercise of the loan commitment might decline from inception of a rate lock to funding of the loan due to increases 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. Forward Loan Sale Commitments With a “mandatory delivery” contract, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. If the Company fails to deliver the number 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 will experience changes in fair value opposite to the change in fair value of derivative loan commitments.

MINIMUM REGULATORY CAPITAL REQUIREMENTS	Jun. 30, 2023
MINIMUM REGULATORY CAPITAL REQUIREMENTS
MINIMUM REGULATORY CAPITAL REQUIREMENTS	12. The Company and the Bank are subject to various regulatory capital requirements administered by the Federal Reserve and the FDIC. Failure to meet minimum capital requirements can result in mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s Consolidated Financial Statements. Under the capital rules, risk-based capital ratios are calculated by dividing Tier 1, common equity Tier 1, and total risk-based capital, respectively, by risk-weighted assets. Assets and off-balance sheet credit equivalents are assigned to one of several risk-weight categories, based primarily on relative risk. The rules require banks and bank holding companies to maintain a minimum common equity Tier 1 capital ratio of 4.5%, a minimum Tier 1 capital ratio of 6.0% and a total capital ratio of 8.0%. In addition, a Tier 1 leverage ratio of 4.0% is required. Additionally, the capital rules require a bank holding company to maintain a capital conservation buffer of common equity Tier 1 capital in an amount above the minimum risk-based capital requirements equal to 2.5% of total risk weighted assets, or face restrictions on the ability to pay dividends, pay discretionary bonuses, and to engage in share repurchases. Under the FDIC’s prompt corrective action rules, an insured state nonmember bank is considered “well capitalized” if its capital ratios meet or exceed the ratios as set forth in the following table and is not subject to any written agreement, order, capital directive, or prompt corrective action directive to meet and maintain a specific capital level for any capital measure. The Bank must meet well capitalized requirements under prompt corrective action provisions. Prompt corrective action provisions are not applicable to bank holding companies. A bank holding company is considered “well capitalized” if the bank holding company (i) has a total risk-based capital ratio of at least 10.0%, (ii) has a Tier 1 risk-based capital ratio of at least 6.0%, and (iii) is not subject to any written agreement order, capital directive or prompt corrective action directive to meet and maintain a specific capital level for any capital measure. At June 30, 2023, the capital levels of both the Company and the Bank exceeded all regulatory capital requirements and their regulatory capital ratios were above the minimum levels required to be considered well capitalized for regulatory purposes. The capital levels of both the Company and the Bank at June 30, 2023 also exceeded the minimum capital requirements, including the currently applicable capital conservation buffer of 2.5%. The Company’s and the Bank’s actual regulatory capital ratios as of June 30, 2023 and December 31, 2022 are presented in the table below.

FAIR VALUE OF ASSETS AND LIABILITIES	Jun. 30, 2023
FAIR VALUE OF ASSETS AND LIABILITIES
FAIR VALUE OF ASSETS AND LIABILITIES	14. FAIR VALUE OF ASSETS AND LIABILITIES Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: •Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. •Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. •Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The following methods and assumptions were used by the Company in estimating fair value disclosures: Debt Securities Level 2 debt securities are traded less frequently than exchange-traded instruments. The fair value of these securities is determined using matrix pricing with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. This category includes obligations of U.S. government-sponsored enterprises, including mortgage-backed securities, individual name issuer trust preferred debt securities and corporate bonds. Debt securities not actively traded whose fair value is determined through the use of cash flows utilizing inputs that are unobservable are classified as Level 3. There were no Level 3 securities held at June 30, 2023 and December 31, 2022. Loans held for sale Collateral-Dependent Impaired Loans Appraisals for collateral-dependent impaired loans are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, the Company reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Retirement plan annuities MSRs Deposits and mortgagors’ escrow accounts Borrowed funds Accrued interest Derivatives Derivatives designated as hedging instrument Forward loan sale commitments and derivative loan commitments Interest rate swaps and risk participation agreements Although the Company has determined that the majority of the inputs used to value its interest rate swaps and risk participation agreements fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with interest rate contracts and risk participation agreements utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. As of June 30, 2023 and December 31, 2022, the Company assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and determined that the credit valuation adjustments were not significant to the overall valuation of its derivatives. As a result, the Company classified its derivative valuations in their entirety as Level 2. Off-balance sheet credit-related instruments Transfers between levels are recognized at the end of the reporting period, if applicable. There were no transfers during the periods presented.

The Company may also use another source of collateral assessment to determine a reasonable estimate of the fair value of the collateral. Appraisals may be adjusted by Management for qualitative factors and estimated liquidation expenses. Generally, appraisals for residential real estate and commercial real estate loan are discounted 20% . Commercial and industrial appraisals are generally discounted 25% - 50% . Management may take larger discounts to reflect market liquidity for certain types of assets not addressed in the appraisals. Summary of Fair Values of Financial Instruments The estimated fair values, and related carrying or notional amounts, of the Company’s financial instruments are as follows.

EARNINGS PER SHARE	15. EARNINGS PER SHARE Basic EPS represents net income attributable to common shareholders divided by the weighted-average number of common shares outstanding during the period. Non-vested restricted shares that are participating securities are included in the computation of basic EPS. Diluted EPS is computed by dividing net income attributable to common shareholders by the weighted-average number of common shares outstanding, plus the effect of potential dilutive common stock equivalents outstanding during the period. At June 30, 2023, potential common shares of 1,308,266 were considered to be anti-dilutive and excluded from EPS. There were no potential shares considered to be anti-dilutive at June 30, 2022.

REVENUE RECOGNITION
REVENUE RECOGNITION	16. REVENUE RECOGNITION Revenue from contracts with customers in the scope of ASC Topic 606 is measured based on the consideration specified in the contract with a customer and excludes amounts collected on behalf of third parties. The Company recognizes revenue from contracts with customers when it satisfies its performance obligations. The Company’s performance obligations are generally satisfied as services are rendered and can either be satisfied at a point in time or over time. Unsatisfied performance obligations at the report date are not material to our Consolidated Financial Statements. In certain cases, other parties are involved with providing services to our customers. If the Company is a principal in the transaction (providing services itself or through a third party on its behalf), revenues are reported based on the gross consideration received from the customer and any related expenses are reported gross in noninterest expense. If the Company is an agent in the transaction (referring to another party to provide services), the Company reports its net fee or commission retained as revenue. The Company recognizes revenue that is transactional in nature and such revenue is earned at a point in time. Revenue that is recognized at a point in time includes card interchange fees (fee income related to debit card transactions), ATM fees, wire transfer fees, overdraft charge fees, and stop-payment and returned check fees. Additionally, revenue is collected from loan fees, such as letters of credit, line renewal fees and application fees. Such revenue is derived from transactional information and is recognized as revenue immediately as the transactions occur or upon providing the service to complete the customer’s transaction.

SEGMENT REPORTING
SEGMENT REPORTING	17. SEGMENT REPORTING The Company has two reportable segments: HarborOne Bank and HarborOne Mortgage. Revenue from HarborOne Bank consists primarily of interest earned on loans and investment securities and service charges on deposit accounts. Revenue from HarborOne Mortgage comprises interest earned on loans and fees received as a result of the residential mortgage origination, sale and servicing process. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies. Segment profit and loss is measured by net income on a legal entity basis. Intercompany transactions are eliminated in consolidation. Information about the reportable segments and reconciliation to the unaudited interim Consolidated Financial Statements at June 30, 2023 and 2022 and for the three and six months ended June 30, 2023 and 2022 is presented in the tables below.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The unaudited interim Consolidated Financial Statements of HarborOne Bancorp, Inc. presented herein have been prepared pursuant to the rules of the SEC for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by GAAP. In the opinion of management, all adjustments and disclosures considered necessary for the fair presentation of the accompanying Consolidated Financial Statements have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements for the years ended December 31, 2022 and 2021 and notes thereto included in the Company’s Annual Report on Form 10-K. The unaudited interim Consolidated Financial Statements include the accounts of the Company; the Company’s subsidiaries, Legion Parkway Company LLC (a security corporation) and HarborOne Bank; and the Bank’s wholly-owned subsidiaries, which consist of HarborOne Mortgage, LLC, HarborOne Security Company, Inc. and a passive investment corporation The passive investment corporation maintains and manages certain assets of the Bank. The security company was established for the purpose of buying, holding and selling securities on its own behalf. All significant intercompany balances and transactions have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year financial statement presentation. These changes and reclassifications did not impact previously reported net income or comprehensive income.
Nature of Operations	Nature of Operations The Company provides a variety of financial services to individuals and businesses through its 30 full-service branches in Massachusetts and Rhode Island, and a commercial lending office in each of Boston, Massachusetts and Providence, Rhode Island. HarborOne Mortgage maintains offices in Florida, Maine, Massachusetts, New Hampshire, New Jersey and Rhode Island and originates loans in five additional states. The Company’s primary deposit products are checking, money market, savings, and term certificate of deposit accounts, while its primary lending products are commercial real estate, commercial, residential mortgages, home equity, and consumer loans. The Company also originates, sells and services residential mortgage loans through HarborOne Mortgage.
Risks and Uncertainties	Risks and Uncertainties During the first quarter of 2023, the banking industry experienced significant volatility with multiple high-profile bank failures and industry-wide concerns related to liquidity, deposit outflows, unrealized securities losses and eroding consumer confidence in the banking system. In response to these events, the Treasury, the Federal Reserve, and the FDIC jointly announced the BTFP on March 12, 2023. This program aims to enhance liquidity by allowing institutions to pledge certain securities at the par value of the securities, and at a borrowing rate of ten basis points over the one-year overnight index swap rate. The BTFP is available to eligible U.S. federally insured depository institutions, with advances having a term of up to one year and no prepayment penalties. Macroeconomic trends are mixed as uncertainty remains about the economy and banking industry. Reliance on secondary funding sources could increase the Company’s overall cost of funds and thereby reduce net income. While the Company believes its current sources of liquidity are adequate to fund operations, there is no guarantee they will suffice to meet future liquidity demands. This may necessitate slowing or discontinuing loan growth, capital expenditures, or other investments, or liquidating assets. Additionally, the Company could experience adverse effects on its business, financial condition, results of operations and cash flows if there is severe or prolonged inflation, a recession, further escalation of the current geopolitical situation, or sustained supply chain disruptions. While asset quality continues to point to economic recovery, the Company’s customers could experience similar adverse effects from these uncertainties that would impair their ability to fulfill their financial obligations to the Company resulting in deteriorating credit quality and loan charge-offs.
Summary of Significant Accounting Policies and Recently Adopted Accounting Standards Updates	Summary of Significant Accounting Policies and Recently Adopted Accounting Standards Updates Significant accounting policies in effect and disclosed within the Company’s most recent audited Consolidated Financial Statements as of December 31, 2022 remain substantially unchanged. In March 2022, the FASB issued ASU 2022-02, “Financial Instruments – Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures” ASU 2022-02 also requires that public business entities disclose current-period gross charge-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, “Financial Instruments—Credit Losses—Measured at Amortized Cost.” The Company adopted ASU 2022-02 effective January 1, 2023 on a modified retrospective basis. The adoption of ASU 2022-02 did not have a material impact on the Company’s Consolidated Financial Statements.
