Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation: The accompanying consolidated financial statements include the accounts of Blue Foundry Bancorp (the “Company”, formerly Boiling Springs Bancorp), and its wholly owned subsidiary, Blue Foundry Bank (the “Bank”), and the Bank’s wholly owned subsidiaries, Blue Foundry Service Corp., Rutherford Center Development Corp., Blue Foundry Investment Company (collectively, the “Company”). The Company’s name change was effective July 1, 2019. All significant intercompany accounts and transactions have been eliminated in consolidation. Blue Foundry Bancorp owns 100% of the common stock of Blue Foundry Bank. On July 15, 2021, the Company became the holding company for the Bank when Blue Foundry, MHC completed its conversion into the stock holding company form of organization. In connection with the conversion, the Company sold 27,772,500 shares of common stock at a price of $10 per share, for gross proceeds of $277.7 million. The Company also contributed 750,000 shares of common stock and $1.5 million in cash to Blue Foundry Charitable Foundation, Inc. Shares of the Company’s common stock began trading on July 16, 2021 on the Nasdaq Global Select Market under the trading symbol “BLFY.” Basis of Financial Statement Presentation: The consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles. The financial statements were prepared in accordance with the instructions for Form 10-Q and with Regulation S-X and do not include information or footnotes necessary for a complete presentation of the financial condition, results of operations, and cash flows in conformity with U.S. generally accepted accounting principles (“GAAP”). The interim unaudited consolidated financial statements reflect all normal and recurring adjustments, which are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the statement of financial condition and revenues and expenses for the period. Actual results could differ from those estimates. Some items in the prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or shareholders’ equity. The results of operations and other data presented for the three and nine months ended September 30, 2021 are not necessarily indicative of the results of operations that may be expected for subsequent periods or the full year results. These financial statements should be read in conjunction with the annual financial statements and notes thereto included in Company’s prospectus, filed with the Securities and Exchange Commission pursuant to Rule 424(b)(3) on May 21, 2021. Loans Receivable: Loans receivable are stated at unpaid principal balance, net of deferred fees, costs, and discounts, and the allowance for loan losses. Interest on loans is recognized based upon the principal amount outstanding. Loan fees and certain direct loan origination costs are deferred, and the net fee or cost is recognized in interest income using the level yield method over the contractual life of the individual loans, adjusted for actual prepayments. For all loan classes, the accrual of income on loans, including impaired loans, is generally discontinued when a loan becomes 90 days delinquent or when certain factors indicate reasonable doubt as to the ability of the borrower to meet contractual principal and/or interest obligations. Loans on which the accrual of income has been discontinued are designated as nonaccrual loans. All previously accrued interest is reversed and income is recognized subsequently only in the period received, provided the remaining principal balance is deemed collectible. A nonaccrual loan is not returned to an accrual status until principal and interest payments are brought current and factors indicating doubtful collection no longer exist. Principal and interest payments received on non-accrual loans for which the remaining principal balance is not deemed collectible are applied as a reduction to principal and interest income is not recognized. If the principal balance on the loan is later deemed collectible and the loan is returned to accrual status, any interest payments that were applied to principal while on non-accrual are recorded as an unearned discount on the loan, classified as deferred fees, costs and discounts, and are recognized into interest income using the level-yield method over the remaining contractual life the individual loan, adjusted for actual prepayments. Allowance for Loan Losses: The allowance for loan losses is a valuation allowance for probable and reasonably estimable incurred credit losses in the loan portfolio as of the balance sheet date. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required for all portfolio segments using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged off. The allowance consists of specific and general components. The specific component of the allowance relates to loans that are individually classified as impaired. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans for which the terms have been modified resulting in a concession and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. 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. Impaired loans are measured based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, or, as a practical expedient, at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. Large groups of smaller balance (generally $400,000 or less) homogeneous loans, such as consumer and residential real estate loans, are collectively evaluated for impairment. Impaired loans also include all nonaccrual non-residential, multifamily and construction and land loans, and troubled debt restructurings. Troubled debt restructured loans are those loans whose terms have been modified such that a concession has been granted because of deterioration in the financial condition of the borrower. Modifications could include extension of the terms of the loan, reduced interest rates, and forgiveness of accrued interest and/or principal. Once an obligation has been classified a troubled debt restructuring, it continues to be considered a troubled debt restructuring and is individually evaluated for impairment until paid in full. For a cash flow dependent loan, the Company records an impairment charge equal to the difference between the present value of the estimated future cash flows under the restructured terms discounted at the loans original effective interest rate, and the original loan’s carrying amount. For a collateral dependent loan, the Company records an impairment when the current estimated fair value, net of estimated costs to sell when necessary, of the property that collateralizes the impaired loan is less than the recorded investment in the loan. The general component of the allowance covers non impaired loans and is based on historical loss experience adjusted for current qualitative factors. The historical loss experience is a quantitative factor determined by portfolio segment and is based on the actual loss history experienced by the Company. These factors include consideration of the following: • Changes in lending policies and procedures, including underwriting standards, collections, and internal loan review practices; • Changes in the nature and volume of the portfolio – increase (decrease) in portfolio category; • Changes in the volume and severity of past due loans – increase (decrease) in loans past due and on non-accrual; • Changes in the volume and severity of past due loans – increase (decrease) in classified loans; • Changes in the ratings for loans from Pass to Watch to Special Mention to Substandard; • Management assessment based on historical Bank performance and peer market data for Probability-Driven Loss Given Default for each loan type, weighted by: o State of the local economy, including regional economic conditions; o Local and regional unemployment; o Delinquency and foreclosure rates in the local market; o Valuations and level of activity in the local housing market; o Other factors, including local and federal government intervention in economic situations which could support or impair credit and valuation, and broader macroeconomic considerations, as well as evolving marketplace, regulatory and legal risk factors The loan portfolio is categorized according to collateral type, loan purpose, lien position, or borrower type (i.e., commercial, consumer). The categories used include residential one-to-four family, multifamily, non-residential, construction and land, junior liens, commercial and industrial (consisting primarily of Paycheck Protection Program, or “PPP”, loans), and consumer and other. Retirement Benefits: Effective January 1, 2020 the Defined Benefit Plan adopted by the Company has been amended to freeze the plan, eliminating all future benefit accruals. The plan was a noncontributory, defined benefit, multiemployer pension plan which covered employees who meet certain eligibility requirements of the plan. Pension plan costs, based upon actuarial assumptions of current and future benefits for employees, are charged to expense and are funded based on the maximum amount that can be deducted for federal income tax purposes. In August, 2021 the Company notified Pentegra of its intent to withdraw from the DB Plan, effective September 30, 2021. The Company recorded an accrued withdrawal liability for the estimated exit price of the defined benefit pension plan, in accordance with ASC 450. The withdraw is expected to close in the fourth quarter of 2021. The Company provides certain healthcare benefits, subject to certain limitations, to eligible retirees, based upon years of service and a retirement date prior to January 1, 2019. The Company also provides supplemental retirement benefits to certain directors. The Company measures the cost of these benefits based upon various estimates and assumptions. Costs are recognized as directors render service. In August, 2021 the Company notified Pentegra of its intent to withdraw from the DB Plan, effective September 30, 2021. The Company recorded an accrued withdrawal liability for the estimated exit price of the defined benefit pension plan, in accordance with ASC 450. The withdrawal is expected to close in the fourth quarter of 2021. Employee Stock Ownership Plan: The cost of shares issued to the ESOP, but not yet allocated to participants, is shown as a reduction of shareholders’ equity. Compensation expense is based on the market price of shares as they are committed to be released to participant accounts. Dividends on allocated ESOP shares reduce retained earnings; dividends on unearned ESOP shares reduce the ESOP’s debt and accrued interest. Earnings per share: Basic earnings per share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Unallocated ESOP shares are not deemed outstanding for earnings per share calculations. ESOP shares committed to be released are considered to be outstanding for purposes of the earnings per share computation. ESOP shares that have not been legally released, but that relate to employee services rendered during an accounting period (interim or annual) ending before the related debt service payment is made, are considered committed to be released. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate to outstanding stock options awards and are determined using the treasury stock method. Adoption of New Accounting Standards: Effective January 1, 2020, the Company adopted ASU No. 2016-02, “Leases (Topic 842)” which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. The new standard establishes a right-of-use model (“ROU”) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The new standard permits entities to use an optional transition method which allows an entity to continue to use guidance from ASC 840 in the comparative periods presented in the adoption year of ASC 842. The optional election also allows entities to utilize several practical expedients including the recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the adoption year. Since all leases at the Company were accounted for as operating leases under ASC 840 and are still considered to be operating leases under ASC 842, no adjustment was needed to retained earnings as of the beginning of the period. Other practical expedients utilized included: –Carry over of historical lease determination and lease classification conclusions –Carry over of historical initial direct cost balances for existing leases –Accounting for lease and non-lease components in contracts in which the Company is a lessee as a single lease component Adoption of the leasing standard resulted in the recognition of operating right-of-use assets of $6.0 million and operating lease liabilities of $6.0 million as of January 1, 2020. These amounts were determined based on the present value of remaining minimum lease payments, discounted using the Company’s incremental borrowing rate at the later of the date of adoption or the date of the lease. There was no material impact to the timing of expense or income recognition in the Company’s Consolidated Income Statements. Accounting Standards Not Yet Adopted: The FASB issued, but the Company has not yet adopted, ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” to replace the incurred loss model for loans and other financial assets with an expected loss models, which is referred to as the current expected credit loss (“CECL”) model. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized costs, including loan receivables and held-to maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in certain leases recognized by a lessor. In addition, the amendments in Topic 326 require credit losses on available-for-sale to be presented as a valuation allowance rather than a direct write-down on the basis of the securities. The Company is required to adopt this standard on January 1, 2023. At this time, the Company cannot reasonably estimate the impact that the adoption of CECL will have on the financial statements, but is in process of developing a methodology to implement the standard.
