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. (the “Company”) presented herein have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by the U.S. generally accepted accounting principles (“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, 2021 and 2020 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 (the “Bank”); and the Bank’s wholly-owned subsidiaries, which consist of HarborOne Mortgage, LLC (“HarborOne Mortgage”), a passive investment corporation, and one security corporation. The passive investment corporation maintains and manages certain assets of the Bank. The security corporation 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 31 full-service branches in Massachusetts and Rhode Island, and commercial lending offices in each of Boston, Massachusetts and Providence, Rhode Island. HarborOne Mortgage maintains 26 offices in Maine, Massachusetts, Rhode Island, and New Hampshire and is licensed to lend in six 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 Macroeconomic trends are mixed as uncertainty remains about the timing and strength of the economy’s recovery from the response to the COVID-19 pandemic. 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, sustained supply chain disruptions, or if there is a resurgence in the virus. 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 (“ASU”) Significant accounting policies in effect and disclosed within the Company’s most recent audited consolidated financial statements as of December 31, 2021 remain substantially unchanged with the exception of the accounting policy for credit losses, commonly referred to as “CECL,” as a result of adopting ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) and subsequent related updates (collectively ASU 2016-13) as described below. ASU 2016-13 was issued in June 2016. ASU 2016-13 requires the measurement of expected lifetime credit losses for financial assets measured at amortized cost, as well as unfunded commitments that are considered off-balance sheet credit exposures at the reporting date. The measurement is based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. For available-for-sale debt securities with unrealized losses, Topic 326 requires credit losses to be recognized as an allowance rather than a reduction in the amortized cost of the securities. As a result, improvements to estimated credit losses are recognized immediately in earnings rather than as interest income over time. ASU 2016-13 provides for a modified retrospective transition, resulting in a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is effective. The Company adopted ASU 2016-13, including the subsequent ASUs issued to clarify Topic 326 (“Topic 326”), on January 1, 2022. The Company assembled a cross-functional project team that met regularly to address the additional data requirements, to determine the approach for implementation and to identify new internal controls over accounting processes for estimating the allowance for credit losses (“ACL”). This included assessing the adequacy of existing loan and loss data, assessing models for default and loss estimates, conducting limited “trial” runs and analytical reviews through December 31, 2021, and completing independent model validation and documentation of ACL processes and controls in the first quarter of 2022. In accordance with Topic 326, the Company has updated its ACL accounting policies. Required policy disclosures are provided in Notes 2, 4, and 9. Upon adoption of Topic 326 on January 1, 2022, the ACL for loans decreased by $1.3 million and the ACL for unfunded commitments increased by $3.9 million, as compared to December 31, 2021. The increases in the ACL on loans and unfunded commitments upon adoption resulted in a one-time cumulative-effect adjustment that decreased retained earnings by $1.9 million, net of deferred tax balances of $737,000. The Company has not elected to use the CECL transition provision provided by regulatory guidance issued by the Federal Deposit Insurance Corporation (“FDIC”) in March 2020, and as such the full impact of the adoption is reflected in Tier 2 capital ratios. See Note 12 for additional disclosure on regulatory capital. ASUs not yet Adopted In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-02, “Financial Instruments – Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures” (“ASU 2022-02”). ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings (“TDRs”) in Accounting Standards Codification (“ASC”) 310-40, “Receivables – Troubled Debt Restructurings by Creditors” for entities that have adopted the current expected credit loss (“CECL”) model introduced by ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). 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.” ASU 2022-02 is effective for the Company for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, with early adoption permitted. The Company is evaluating the effect that ASU 2022-02 will have on its consolidated financial statements and related disclosures.
