NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation: The accompanying consolidated financial statements include the accounts of Blue Foundry Bancorp (the “Company”), 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., and Blue Foundry Investment Company (collectively, the “Company”). All 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. and established an Employee Stock Ownership Plan (“ESOP”) acquiring 2,281,800 shares of common stock. Shares of the Company’s common stock began trading on July 16, 2021 on the Nasdaq Global Select Market under the trading symbol “BLFY.”

Segment Reporting: The Company operates as a single operating segment for financial reporting purposes.

Basis of Financial Statement Presentation: The consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles. Certain information and note disclosures usually included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for the preparation of the Quarterly Reports on Form 10-Q and with Regulation S-X. 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 consolidated balance sheets and the consolidated statements of income 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 consolidated balance sheets and revenues and expenses for the period. Actual results could differ from those estimates. Some items in the prior year financial statements may be 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, 2023 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 the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed on March 30, 2023.

The accounting policies of the Company conform to U.S. GAAP and to general practice within the financial services industry. A discussion of these policies can be found in Note 1, Summary of Significant Accounting Policies, included in the Company’s 2022 Annual Report on Form 10-K. Except for the below, there have been no changes to the Company’s significant accounting policies since December 31, 2022.

Adoption of New Accounting Standards: The Company adopted Accounting Standards Update (“ASU”) 2020-04, “Reference Rate Reform (“ASU 2020-04”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts and hedging relationships, subject to meeting certain criteria, that reference the London Inter-Bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance was effective for all entities as of March 12, 2020 through December 31, 2022. However, in December 2022, the FASB issued ASU 2022-06, deferring the sunset date to December 31, 2024. The Company has evaluated the regulatory requirements to cease the use of LIBOR and has put in place systems and capabilities for this purpose.

The Company adopted ASU No. 2016-13, “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments,” which replaces the incurred loss model for loans and other financial assets with an expected loss model and is referred to as the current expected credit loss (“CECL”) model. The Company adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and off-balance-sheet credit exposures. The adoption of the new standard resulted in the Company recording an increase in the allowances for credit losses of $18 thousand, comprised of an increase of $660 thousand on loans, establishing a $170 thousand reserve on held-to-maturity securities and a reversal in the reserve for commitments and letters of credit of $811 thousand. There was no allowance for credit losses required on available-for-sale securities. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loans receivable and held-to maturity debt securities. It also applies to off-balance-sheet credit exposures (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 ASU 2016-13 require credit losses on available-for-sale securities to be presented as a valuation allowance rather than a direct write-down on the basis of the securities. Results for reporting periods beginning after January 1, 2023, are presented under CECL, while prior period amounts continue to be presented under previously-applied U.S. GAAP.

Loans

Under the CECL model, the allowance for credit losses on financial assets is a valuation allowance estimated at each balance sheet date in accordance with U.S. GAAP, and is deducted from the financial assets’ amortized cost basis to present the net amount expected to be collected on the financial assets.

The Company estimates the allowance for credit losses on loans based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for applicable accretion or amortization of premium, discount, net deferred fees or costs, collection of cash, and charge-offs. In the event that collection of principal becomes uncertain, the Company has policies in place to write-off accrued interest receivable by reversing interest income in a timely manner. Therefore, the Company has made a policy election to exclude accrued interest from the amortized cost basis and therefore excludes it from the measurement of the allowance for credit loss.

Changes in expected credit losses are reflected through a charge to the provision for credit losses. The Company’s estimate of the allowance for credit loss reflects losses expected over the remaining contractual life of the assets. When the Company deems all or a portion of a financial asset to be uncollectible, the appropriate amount is written off and the allowance for credit losses is reduced by the same amount. The Company applies judgment to determine when a financial asset is deemed uncollectible. When available information confirms that specific loans, securities, other assets, or portions thereof, are uncollectible, these amounts are charged-off against the allowance for credit losses. Subsequent recoveries, if any, are credited to the allowance for credit losses when received.

The Company measures expected credit losses of financial assets on a collective portfolio segment basis when the financial assets share similar risk characteristics. The Company generally measures expected credit losses using discounted cash flows (“DCF”) models at the portfolio segment level, whereby the total shortfall in comparing the portfolio segment DCFs to the amortized cost basis reflects management’s estimate of expected credit losses.

Our CECL models for loans includes the following major items:

–a historical loss period, which represents a full economic credit cycle utilizing loss experience including peer bank historical loss data, to calculate probabilities of default at the portfolio segment level;

–macroeconomic variable forecasts, including the national housing price index, unemployment and gross domestic product, to adjust probabilities of default over a reasonable and supportable forecast period of one year, based on management’s current review of the reliability of extended forecasts;

–a reversion period of one year to adjust probabilities of default (after the reasonable and supportable forecast period) to historical means using a straight-line approach;

–a risk index that measures loss given defaults as a function of probabilities of default at the portfolio segment level;

11

BLUE FOUNDRY BANCORP

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

–expected prepayment rates based on our historical experience and benchmark assumptions where internal data is limited; and

–incorporation of qualitative factors not captured within the modeled results.

For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable and where the borrower is experiencing financial difficulty, the allowance for credit loss is measured based on the difference between the fair value of the collateral and the amortized cost basis of the asset as of the measurement date. Fair value is calculated based on the value of the underlying collateral less an appraisal discount and the estimated cost to sell.

Off-Balance-Sheet Exposures

The Company records changes in the allowance for credit losses on off-balance-sheet credit exposures through a charge to provision for credit losses. The allowance for credit loss on off-balance-sheet credit exposures is estimated by portfolio segment at each balance sheet date under the CECL model using the same methodologies as portfolio loans, taking into consideration management’s assumption of the likelihood that funding will occur, and is included in other liabilities on the Company’s consolidated balance sheets.

Securities

For securities available-for-sale, ASU 2016-13 eliminates the concept of other-than-temporary impairment and instead requires entities to determine if impairment is related to credit loss or non-credit loss. In making the assessment of whether a loss is from credit or other factors, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost basis, a credit loss exists and an allowance is created, limited by the amount that the fair value is less than the amortized cost basis.

The allowance for credit losses on held-to-maturity debt securities is initially recognized upon acquisition of the securities, and subsequently remeasured on a recurring basis. Expected credit losses on held-to-maturity debt securities through the life of the financial instrument are estimated and recognized as an allowance for credit losses on the balance sheet with a corresponding adjustment to current earnings. Subsequent favorable or unfavorable changes in expected cash flow will decrease or increase the allowance for credit losses through a charge to the provision for credit losses.

Management measures expected credit losses on held-to-maturity securities on a collective basis by major security type. The held-to-maturity portfolio is classified into the following major security types: corporate bonds and asset-backed securities.

At each reporting period, the Company evaluates whether the securities in a segment continue to exhibit similar risk characteristics as the other securities in the segment. If the risk characteristics of a security change, such that they are no longer similar to other securities in the segment, the Company will evaluate the security with a different segment that shares more similar risk characteristics.

The Company has a non-accrual policy that results in a timely reversal of interest receivable, therefore the Company made the election to exclude accrued interest receivable on securities from the estimate of credit losses.

In addition, the Company adopted ASU No. 2022-02, “Financial Instruments - Credit Losses (“ASU 2022-02”): Troubled Debt Restructurings (“TDR”) and Vintage Disclosures.” The amendments in this ASU were issued to (1) eliminate accounting guidance for TDRs by creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty; (2) require disclosures of current period gross write-offs by year of origination for financing receivables and net investments in leases. The amendments in this ASU were applied on a modified retrospective basis to recognize any change in the allowance for credit losses that had been recognized for receivables previously modified (or reasonably expected to be modified) in a TDR. This election resulted in a cumulative-effect adjustment to retained earnings as of January 1, 2023 of $8 thousand.

Credit Quality Indicators

Credit ratings are a key measure for estimating the probability of a bond’s default and for monitoring credit quality on an on-going basis. For bonds other than U.S. Treasuries and bonds issued or guaranteed by U.S. government agencies, credit ratings issued by one or more nationally recognized statistical rating organization are considered in conjunction with an assessment by the Company’s management. Investment grade reflects a credit quality of BBB- or above. None of the Company’s securities are on non-accrual status, nor are any past due.

The table below indicates the credit profile of the Company’s debt securities held-to-maturity at amortized cost at September 30, 2023.

Loans are recorded at amortized cost, which includes principal balance, net deferred fees or costs, premiums and discounts. The Company elected to exclude accrued interest receivable from amortized cost. Accrued interest receivable is reported separately in the consolidated balance sheets and totaled $6.0 million and $5.3 million at September 30, 2023 and December 31, 2022, respectively. Loan origination fees and certain direct loan origination costs are deferred and the net fee or cost is recognized in interest income as an adjustment of yield. At September 30, 2023, net deferred loan fees are included in loans by respective segment and totaled $2.2 million.

The portfolio classes in the above table have unique risk characteristics with respect to credit quality:

•Payment on multifamily and non-residential mortgages is driven principally by operating results of the managed properties or underlying business and secondarily by the sale or refinance of such properties. Both primary and secondary sources of repayment and the value of the properties in liquidation, may be affected to a greater extent by adverse conditions in the real estate market or the economy in general.

•Properties underlying construction loans often do not generate sufficient cash flows to service debt and thus repayment is subject to the ability of the borrower and, if applicable, guarantors, to complete development or construction of the property and carry the project, often for extended periods of time. As a result, the performance of these loans is contingent upon future events whose probability at the time of origination is uncertain.

•Commercial and industrial (“C&I”) loans include C&I revolving lines of credit, term loans, SBA 7a loans and to a lesser extent, Paycheck Protection Program (“PPP”) loans. Payments on C&I loans are driven principally by the cash flows of the businesses and secondarily by the sale or refinance of any collateral securing the loans. Both the cash flow and value of the collateral in liquidation may be affected by adverse general economic conditions.

•The ability of borrowers to service debt in the residential one-to-four family, junior liens and consumer loan portfolios is generally subject to personal income which may be impacted by general economic conditions, such as increased unemployment levels. These loans are predominately collateralized by first and second liens on single family properties. If a borrower cannot maintain the loan, the Company’s ability to recover against the collateral in sufficient amount and in a timely manner may be significantly influenced by market, legal and regulatory conditions.

Credit Quality Indicators

The Company categorizes loans into risk categories based on relevant information about the quality and realizable value of collateral, if any, and the ability of borrowers to service their debts such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans by credit risk. This analysis is performed whenever credit is extended, renewed, or modified, or when an observable event occurs indicating a potential decline in credit quality, and no less than annually for large balance loans. The Company used the following definitions for risk ratings for loan classification:

Pass – Loans classified as pass are loans performing under the original contractual terms, do not currently pose any identified risk and can range from the highest to pass/watch quality, depending on the degree of potential risk.

Special Mention – Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or the Company’s credit position at some future date.

Substandard – Loans classified as substandard are inadequately protected by the current sound worth and paying capacity of the obligor, or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the repayment and liquidation of the debt. They are characterized by a distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

Doubtful – Loans classified as doubtful have all the weaknesses inherent in those classified as Substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions, and values, highly questionable and improbable.

18

BLUE FOUNDRY BANCORP

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Loss – Assets classified as loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted.  This classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off the asset even though partial recovery may be effected in the future.

The recorded investment in loans includes deferred fees, costs and discounts. For purposes of this disclosure, the unpaid principal balance would not be reduced for partial charge-offs.

The Company adopted ASU 2022-02 on January 1, 2023. Modifications made to borrowers experiencing financial difficulty may include principal forgiveness, interest rate reductions, other than insignificant payment delays, terms extensions or a combination thereof. At September 30, 2023, loans with modifications to borrowers experiencing financial difficulty totaled $5.5 million. These loans included one construction loan of $3.5 million and one residential loan of $374 thousand related to term extensions and two residential loans of $1.6 million related to other than insignificant payment delays. The Company did not reclassify comparative financial periods and has presented those disclosures under previously-applied U.S. GAAP.

Prior to the adoption of ASU 2022-02, the Company classified certain loans as troubled debt restructuring (“TDR”) loans when credit terms to a borrower in financial difficulty were modified in accordance with ASC 310-40. The total recorded investment of loans whose terms were modified in TDRs was $4.8 million as of December 31, 2022. The Company allocated $27 thousand of specific reserves to TDR loans as of December 31, 2022. The modification of the terms of TDR loans may have included one or a combination of the following: a reduction of the stated interest rate of the loan, short-term deferral of payment, or an extension of the maturity date.

A TDR loan was considered to be in payment default once it is 90 days contractually past due under the modified terms. There were no TDRs for which there was a payment default within twelve months following the modification during the period ended September 30, 2022. There were no TDRs during the three months ended September 30, 2022 and TDRs totaled $453 thousand during the nine months ended September 30, 2022.

The Company had $3.8 million and $4.5 million in consumer mortgage loans secured by residential real estate properties for which foreclosure proceedings are in process at September 30, 2023 and December 31, 2022, respectively. At September 30, 2023, the Company had one one-to-four family loan with a carrying value of $593 thousand in real estate owned. There was no real estate owned at December 31, 2022.

NOTE 4 – ALLOWANCE FOR CREDIT LOSSES

On January 1, 2023, the Company adopted ASU 2016-13, which requires the measurement of expected credit losses for financial assets measured at amortized cost, including loans, held-to-maturity securities and certain off-balance-sheet credit exposures and ASU 2022-02, which eliminates the recognition and measurement guidance of TDRs, so that creditors will apply the same guidance to all modifications when determining whether a modification results in a new receivable or continuation of an existing receivable. See Note 1 - Summary of Significant Accounting Policies for a description of the adoption of ASU 2016-13 and the Company’s allowance methodology.

Under ASU 2016-13, the Company’s methodology for determining the allowance for credit losses on loans is based upon key assumptions, including the lookback period, historical loss experience, economic forecasts over a reasonable and supportable forecast period, reversion period, prepayments and qualitative adjustments. The allowance is measured on a pool basis when similar risk characteristics exist. Loans that do not share common risk characteristics are evaluated on an individual basis and are excluded from the collective evaluation.

Allowance for Credit Losses - Securities

The Company recorded an allowance of credit losses on securities of $170 thousand upon adoption of ASU 2016-13 on January 1, 2023. Prior year disclosures have not been restated. At September 30, 2023, the balance of the allowance of credit losses on securities was $168 thousand. For the three and nine months ended September 30, 2023, the Company recorded a decrease in provision for credit losses of $2 thousand on held-to-maturity securities. Accrued interest receivable on securities is reported as a component of accrued interest receivable on the consolidated balance sheets and totaled $1.8 million and $1.0 million at September 30, 2023 and December 31, 2022, respectively. The Company made the election to exclude accrued interest receivable from the estimate of credit losses on securities.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Allowance for Credit Losses - Off-Balance-Sheet Exposures

The allowance for credit losses on off-balance-sheet exposures is reported in other liabilities in the consolidated balance sheets. The liability represents an estimate of expected credit losses arising from off-balance-sheet exposures such as letters of credit, guarantees and unfunded loan commitments. The process for measuring lifetime expected credit losses on these exposures is consistent with that for loans as discussed above, but is subject to an additional estimate reflecting the likelihood that funding will occur. No liability is recognized for off-balance-sheet credit exposures that are unconditionally cancellable by the Company. Adjustments to the liability are reported as a component of provision for credit losses.

The Company recorded a decrease in the allowance for credit losses for off-balance-sheet exposures of $811 thousand upon adoption on January 1, 2023. Prior year disclosures have not been restated. At September 30, 2023 and December 31, 2022, the balance of the allowance for credit losses for off-balance-sheet exposures was $435 thousand and $1.7 million, respectively. The Company recorded a recovery of provision for credit loss on off-balance-sheet exposures of $201 thousand and $443 thousand for the three and nine months ended September 30, 2023, respectively. For the three and nine months ended September 30, 2022, the Company recorded a provision on unfunded lending commitments of $170 thousand and a recovery of $108 thousand, respectively, in other non-interest expense.

NOTE 5 – LEASES

The Company leases certain office space, land and equipment under operating leases. These leases have original terms ranging from one year to 40 years. Operating lease liabilities and right-of-use assets are recognized at the lease commencement date based on the present value of the future minimum lease payments over the lease term.

NOTE 7 - STOCK-BASED COMPENSATION

Employee Stock Ownership Plan

The Company maintains an ESOP, a tax-qualified plan designed to invest primarily in the Company’s common stock. The ESOP provides employees with the opportunity to receive a funded retirement benefit from the Bank, based primarily on the value of the Company’s common stock.

The ESOP borrowed funds from the Company to purchase 2,281,800 shares of stock at $10 per share. The loan is secured by the shares purchased, which are held until allocated to participants. Shares are released for allocation to participants as loan payments are made. Loan payments are principally funded by discretionary cash contributions by the Bank, as well as dividends, if any, paid to the ESOP on unallocated shares. When loan payments are made, ESOP shares are allocated to participants at the end of the plan year (December 31) based on relative compensation, subject to federal tax law limits. Participants receive the allocated vested shares at the end of employment. Dividends on allocated shares, if any, increase participants accounts.

At September 30, 2023, the principal balance on the ESOP loan was $21.2 million. There were no contributions to the ESOP during the three and nine months ended September 30, 2023, as loan payments are made annually during the fourth quarter of each year. ESOP shares are committed to be released from unallocated and compensation expense is recognized over the service period. At September 30, 2023 and December 31, 2022, there were 2,099,256 unallocated shares and 182,544 shares allocated to participants. The fair value of unallocated shares at September 30, 2023 and December 31, 2022 was $17.6 million and $27.0 million, respectively, computed using the closing trading price of the Company’s common stock on each date.

For the three and nine months ended September 30, 2023, ESOP compensation expense for the shares committed to be released from unallocated was $216 thousand and $699 thousand respectively. Shares committed to be released from unallocated total 22,818 and 68,454 for the three and nine months ended September 30, 2022, respectively. During the three and nine months ended September 30, 2022, the Company recorded $266 thousand and $870 thousand, respectively, of ESOP compensation expense.

Equity Incentive Plan

At the annual meeting held on August 25, 2022, stockholders of the Company approved the Blue Foundry Bancorp 2022 Equity Incentive Plan (“Equity Plan”) which provides for the granting of up to 3,993,150 shares (1,140,900 restricted stock awards and 2,852,250 stock options) of the Company’s common stock.

Restricted shares granted under the Equity Plan generally vest in equal installments, over a service period between five and seven years beginning one year from the date of grant. Additionally, certain restricted shares awarded can be performance vesting awards, which may or may not vest depending upon the attainment of certain corporate financial targets. The vesting of the awards accelerate upon death, disability or an involuntary termination at or following a change in control. The product of the number of shares granted and the grant date closing market price of the Company’s common stock determine the fair value of restricted shares under the Equity Plan. Management recognizes compensation expense for the fair value of restricted shares on a straight-line basis over the requisite service period.

Stock options granted under the Equity Plan generally vest in equal installments, over a service period between five and seven years beginning one year from the date of grant. The vesting of the options accelerate upon death, disability or an involuntary termination at or following a change in control. Stock options were granted at an exercise price equal to the fair value of the Company’s common stock on the grant date based on the closing market price and have an expiration period of ten years.

There were no stock options granted during the nine months ended September 30, 2023. The fair value of stock options granted during 2022 were estimated utilizing the Black-Scholes option pricing model using the following assumptions: an expected life of 6.5 years, risk-free rate of 3.15%, volatility of 29.74% and a dividend yield of 0.88%. Due to the limited historical information of the Company’s stock, management considered the weighted historical volatility of the Company and similar entities for an appropriate period in determining the volatility rate used in the estimation of fair value. The expected life of the stock option was estimated using the simplified method. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The Company recognizes compensation expense for the fair values of these awards, which have straight-line vesting, on a straight-line basis over the requisite service period of the awards. Upon exercise of vested options, management expects to draw on treasury stock as the source for shares.

The following table presents the share-based compensation expense for the three and nine months ended September 30, 2023 and 2022.

Expected future expense relating to the non-vested options outstanding as of September 30, 2023 is $8.6 million over a weighted average period of 5.5 years.

On March 6, 2023, the Company granted to employees, under the 2022 Equity Incentive Plan, 372,540 restricted stock awards with a total grant-date fair value of $4.5 million. Of these grants, 12,300 vest one year from the date of grant and 360,240 vest in equal installments over a seven-year period beginning one year from the date of grant. The Company also issued 360,240 performance-based restricted stock awards to its officers with a total grant date fair value of $4.3 million. Vesting of the performance-based restricted stock units will be based on achievement of certain levels of loan growth, deposit growth and net interest margin and will convert to a seven-year time vest after the one-year measurement period ending December 31, 2023. At the end of the performance period, the number of actual shares to be awarded may vary between 0% and 100% of target amounts.

NOTE 8 – DERIVATIVES AND HEDGING ACTIVITIES

The Company utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. The notional amount of the interest rate swaps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements.

The Company had interest rate swaps with notional amounts totaling $259.0 million and $109.0 million at September 30, 2023 and December 31, 2022, respectively. As of September 30, 2023, they were designated as cash flow hedges of certain Federal Home Loan Bank (“FHLB”) advances and brokered deposits and, as of December 31, 2022, they were designated as cash flow hedges of certain Federal Home Loan Bank (“FHLB”) advances. They were determined to be highly effective during all periods presented. The Company expects the hedges to remain highly effective during the remaining terms of the swaps.

Summary information about the interest rate swaps designated as cash flow hedges as of period-end is as follows:

	September 30, 2023			December 31, 2022
	(Dollars in thousands)
Notional amounts	$	259,000		$	109,000

Unrealized gains, net	$	14,350		$	11,091

At September 30, 2023, the Company held $15.3 million as cash collateral pledged from the counterparty for these interest-rate swaps and had no securities pledged to the counterparty. At December 31, 2022, the Company held $11.5 million as cash collateral pledged from the counterparty and had no securities pledged to the counterparty.

Interest income or expense recorded on these swap transactions is reported as a component of interest expense on FHLB advances or brokered deposits. Interest income during the three months ended September 30, 2023 totaled $1.5 million and interest income for the three months ended September 30, 2022 totaled $198 thousand. Interest income during the nine months ended September 30, 2023 totaled $3.9 million and interest expense for the nine months ended September 30, 2022 totaled $270 thousand. At September 30, 2023, the Company expected $1.8 million of the unrealized gain to be reclassified as a reduction to interest expense during the remainder of 2023.

NOTE 10 – 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 Company used the following methods and significant assumptions to estimate fair value:

Securities: For securities available-for-sale, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input as defined by ASC 820, is a mathematical technique used principally to value certain securities to benchmark or comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. The Company also holds debt instruments issued by the U.S. government and U.S. government sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs.

Derivatives: The fair values of derivatives are based on valuation models using observable market data as of the measurement date (Level 2). The Company’s derivatives are traded in an over-the-counter market where quoted market prices are not always available. Therefore, the fair values of derivatives are determined using quantitative models that utilize multiple market inputs. The inputs will vary based on the type of derivative, but could include interest rates, prices and indices to generate continuous yield or pricing curves, prepayment rates and volatility factors to value the position. The majority of market inputs are actively quoted and can be validated through external sources, including brokers, market transactions and third-party pricing services.

Impaired loans: The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value.

Other real estate owned (OREO): Property acquired through foreclosure or deed in lieu of foreclosure is carried at fair value less estimated disposal costs of the acquired property. Fair value of OREO is based on the appraised value of the collateral using discount rates similar to those used in impaired loan valuation.

Assets held for sale: Nonrecurring adjustments to certain non-residential properties classified as assets held for sale are measured at fair value, less costs to sell. Fair values are based on contracts or letters of intent.

Other Fair Value Disclosures

Fair value estimates, methods and assumptions for the Company’s financial instruments that are not recorded at fair value on a recurring or non-recurring basis are set forth below.

Securities held-to-maturity: The Company’s debt securities held-to-maturity portfolio is carried at amortized cost less allowance for credit losses. The fair values of debt securities held-to-maturity are provided by a third-party pricing service. The pricing service may use quoted market prices of comparable instruments or a variety of other forms of analysis, incorporating inputs that are currently observable in the markets for similar securities. Inputs that are often used in the valuation methodologies include, but are not limited to, benchmark yields, credit spreads, default rates, prepayment speeds and non-binding broker quotes.

Loans, net: Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type, such as residential mortgage and consumer. Each loan category is further segmented into fixed and adjustable rate interest terms and by performing and non-performing categories. Estimated fair value of loans is determined using a discounted cash flow model that employs an exit discount rate that reflects the current market pricing for loans with similar characteristics and remaining maturity, adjusted for estimated credit losses inherent in the portfolio at the balance sheet date.

Time deposits: The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using rates for currently offered deposits of similar remaining maturities.

37

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Federal Home Loan Bank advances: The fair value of borrowings is based on securities dealers’ estimated fair values, when available, or estimated using discounted cash flow analysis. The discount rates used approximate the rates offered for similar borrowings of similar remaining terms.

The following tables present the book value, fair value, and placement in the fair value hierarchy of financial instruments not recorded at fair values in their entirety on a recurring basis on the Company’s consolidated balance sheets at September 30, 2023 and December 31, 2022.

These tables exclude financial instruments for which the carrying amount approximates fair value. Financial instruments for which the carrying amount approximates fair value include cash and cash equivalents, other investments, non-maturity deposits, overnight borrowings and accrued interest, which are excluded from the table below.

The following table presents the Company’s sources of revenue from contracts with customers for the three and nine months ended September 30, 2023 and 2022, respectively:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
	(In thousands)
Service charges on deposits	$	205	$	255	$	636	$	752
Interchange income	13		12		38		31
Total revenue from contracts with customers	$	218	$	267	$	674	$	783

Service Charges on Deposit Accounts: The Company earns fees from its deposit customers for transaction-based, account maintenance and, prior to November 1, 2022, overdraft services. Transaction based fees, which include services such as ATM use fees, stop payment charges, statement rendering and wire transfer fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. When they were assessed, overdraft fees were recognized at the point in time the overdraft occurred. Service charges on deposits are withdrawn from the customer’s account balance.

Interchange Income: The Company earns interchange fees from debit cardholder transactions conducted through a payment network. Interchange fees from debit cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. In addition, the Company earns interchange fees from credit cardholder transactions through its partnership with a third party.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 12 - EARNINGS PER SHARE

Basic earnings per share (“EPS”) represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common shares (such as unexercised stock options and unvested restricted stock) were exercised or converted into additional common shares that would then share in the earnings of the entity. Diluted EPS is computed by dividing net income attributable to common shareholders by the weighted-average number of common shares outstanding for the period, plus the effect of potential dilutive common share equivalents.

Shares held by the Employee Stock Ownership Plan (“ESOP”) that have not been allocated to employees in accordance with the terms of the ESOP, referred to as “unallocated ESOP shares,” are not deemed outstanding for earnings per share calculations.

Excluded from the earnings per share calculation are anti-dilutive equity awards for the three and nine months ended September 30, 2023, totaling 1,496,475 and 1,278,351, respectively. For the three and nine months ended September 30, 2022, anti-dilutive equity awards totaling 98,000 and 33,000, respectively, were excluded from the earnings per share calculation. Due to the Company’s net loss for the three and nine months ended September 30, 2023, the assumed vesting of outstanding restricted stock units had an antidilutive effect on diluted earnings per share.

NOTE 13 - SUBSEQUENT EVENTS

As defined in FASB ASC 855, “Subsequent Events,” subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued or available to be issued. Financial statements are considered issued when they are widely distributed to stockholders and other financial statement users for general use and reliance in a form and format that complies with U.S. GAAP. The Company performed an evaluation and determined that there are no subsequent events to report.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This section is intended to assist in the understanding of the financial performance of the Company and its subsidiary through a discussion of our financial condition as of September 30, 2023, and our results of operations for the three and nine month periods ended September 30, 2023 and 2022. This section should be read in conjunction with the unaudited interim condensed consolidated financial statements and notes thereto of the Company appearing in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Forward-Looking Statements

Certain statements contained in this Quarterly Report on Form 10-Q that are not historical facts may be considered forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and are intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These statements, which are based on certain current assumptions and describe our future plans, strategies and expectations, can generally be identified by the use of the words “may,” “will,” “should,” “could,” “would,” “plan,” “potential,” “estimate,” “project,” “believe,” “intend,” “anticipate,” “expect,” “target” and similar expressions.

Forward-looking statements are based on current beliefs and expectations of management and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control. In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change. The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statements: inflation and changes in the interest rate environment that reduce our margins and yields, the fair value of financial instruments or our level of loan originations, or increase the level of defaults, losses and prepayments on loans we have made and make; adverse changes in the securities or secondary mortgage markets; changes in monetary or fiscal policies of the U.S. Government, including policies of the U.S. Treasury and the Federal Reserve Board; general economic conditions, either nationally or in our market areas, that are worse than expected; changes in the level and direction of loan delinquencies and write-offs and changes in estimates of the adequacy of the allowance for credit losses; our ability to access cost-effective funding; fluctuations in real estate values and both residential and commercial real estate market conditions; demand for loans and deposits in our market area; our ability to implement and change our business strategies; competition among depository and other financial institutions; changes in laws or government regulations or policies affecting financial institutions, including changes in regulatory fees, capital requirements and insurance premiums; the effects of the recent turmoil in the banking industry (including the failure of three financial institutions); changes in the quality or composition of our loan or investment portfolios; technological changes that may be more difficult or expensive than expected; a failure or breach of our operational or security systems or infrastructure, including cyber-attacks; the inability of third party providers to perform as expected; our ability to manage market risk, credit risk and operational risk in the current economic environment; our ability to enter new markets successfully and capitalize on growth opportunities; our ability to successfully integrate into our operations any assets, liabilities, customers, systems and management personnel we may acquire and our ability to realize related revenue synergies and cost savings within expected time frames and any goodwill charges related there to; changes in consumer spending, borrowing and savings habits; changes in accounting policies and practices, as may be adopted by the bank regulatory agencies, the Financial Accounting Standards Board, the Securities and Exchange Commission or the Public Company Accounting Oversight Board; our ability to retain key employees; the current or anticipated impact of military conflict, terrorism or other geopolitical events; the impact of potential government shutdown; the ability of the U.S. Government to manage federal debt limits; and changes in the financial condition, results of operations or future prospects of issuers of securities that we own.

Because of these and other uncertainties, our actual future results may be materially different from the results indicated by these forward-looking statements. Except as required by applicable law or regulation, we do not undertake, and we specifically disclaim any obligation, to release publicly the results of any revisions that may be made to any forward-looking statements to reflect events or circumstances after the date of the statements or to reflect the occurrence of anticipated or unanticipated events.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and assumptions. Our actual results could differ from these estimates.

On January 1, 2023, the Company adopted new accounting guidance, which requires entities to estimate and recognize an allowance for lifetime expected credit losses for loans and other financial assets measured at amortized cost. Previously, an allowance was recognized based on probable and reasonably estimable incurred losses inherent in the loan portfolio at the balance sheet date. See Note 1 to our Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for further discussion of the Company’s accounting policies and methodologies for establishing the allowance and the liability for off-balance-sheet commitments beginning in 2023.

The allowance for credit losses is a critical accounting estimate for the following reasons:

•estimates relating to the allowance for credit losses require management to project future loan performance, including cash flows, delinquencies, charge-offs and collateral values, based on a reasonable and supportable forecast period utilizing forward-looking economic scenarios in order to estimate potential credit losses;

•the allowance for credit losses is influenced by factors outside of management’s control such as industry and business trends, geopolitical events and the effects of laws and regulations as well as economic conditions including, but not limited to, interest rates, housing prices, GDP, inflation and unemployment; and

•judgment is required to determine whether the models used to generate the allowance for credit losses produce results that appropriately reflect a current estimate of lifetime expected credit losses.

Because management’s estimates of the allowance for credit losses involve a high degree of judgment, the subjectivity of the assumptions used and the potential for changes in the forecasted economic environment that could result in changes to the amount of the allowance recorded, there is uncertainty inherent in such estimates. Changes in these estimates could significantly impact the allowance and provision for credit losses.

Comparison of Operating Results for the Three Months Ended September 30, 2023 and 2022

General. The Company recorded a net loss of $1.4 million for the three months ended September 30, 2023, compared to net income of $1.2 million for the three months ended September 30, 2022.

Interest Income. Interest income increased $3.8 million, or 23.2%, to $20.2 million for the three months ended September 30, 2023 from $16.4 million for the three months ended September 30, 2022, driven by increases in rates earned on most categories of interest-earning assets and an increase in the average balance of loans of $112.1 million. The yield on average interest-earning assets increased 60 basis points to 3.97% for the three months ended September 30, 2023 from 3.37% for the three months ended September 30, 2022.

Interest Expense. Interest expense was $10.3 million for the three months ended September 30, 2023 compared to $2.6 million for the three months ended September 30, 2022, an increase of $7.7 million driven by increases in rates paid on interest-bearing liabilities and an increase in the average balance of FHLB advances. Average balances of FHLB advances and time deposits increased $151.7 million and $152.4 million, respectively, while the average balances of interest-bearing core deposits decreased $147.0 million when compared to the third quarter of 2022. The cost of average interest-bearing liabilities increased 180 basis points to 2.49% for the three months ended September 30, 2023 from 0.69% for the three months ended September 30, 2022.

Net Interest Income. For the three months ended September 30, 2023 and 2022, net interest income was $9.9 million and $13.8 million, respectively. Net interest spread decreased 120 basis points to 1.48% and net interest margin decreased 90 basis points to 1.94%.

Provision for Credit Losses. The Company recorded a $717 thousand release of provision for credit losses for the three months ended September 30, 2023, compared to a $419 thousand release of provision for loan losses for the same period of 2022. Under prior accounting guidance the release of provision in the third quarter of 2022 excluded the provision on commitments and letters of credit, which was recorded in non-interest expense. For September 30, 2023, the release of provision reflected a release of $514 thousand on loans and a release of $201 thousand on commitments and letters of credit due to the impact of the change in forecast on the loan portfolio, coupled with a decline in unused lines. In addition, the release of provision included a $2 thousand release on securities. As of September 30, 2023, the Allowance for Credit Losses (“ACL”) on loans as a percentage of total loans was 0.88%.

Non-interest Income. Non-interest income decreased $430 thousand, or 53.8%, to $369 thousand for the third quarter of 2023 from $799 thousand for the third quarter of 2022. The decrease in non-interest income from the prior year period was primarily related to loan prepayment fee activity and the absence of overdraft fees. Prepayment fees decreased $218 thousand. Beginning in November 2022, the Company no longer charges overdraft fees; therefore, there were no fees for the third quarter of 2023, while these fees totaled $79 thousand for the third quarter of 2022.

Non-interest Expense. Non-interest expense decreased $1.3 million to $12.4 million for the third quarter of 2023 when compared to the same period in 2022. Excluding the provision for commitments and letters of credit, which prior to January 1, 2023 was recorded in non-interest expense, non-interest expense decreased $1.1 million. This decrease was primarily driven by decreases of $793 thousand in compensation and benefits expenses and $366 thousand decrease in professional fees, partially offset by increases of $183 thousand in occupancy and equipment and $165 thousand in the FDIC assessment.

Income Tax Expense. The Company’s current tax position reflects the previously established full valuation allowance on its deferred tax assets. At September 30, 2023, the valuation allowance on deferred tax assets was $23.1 million. The Company did not record a tax benefit for the loss incurred during the current quarter due to the full valuation allowance required on its deferred tax assets. The third quarter 2022 effective tax rate of 9.0% was a result of the taxable income produced during the prior year quarter, partially offset by the ability to utilize a portion of the net operating losses that were fully reserved.

Comparison of Operating Results for the Nine Months Ended September 30, 2023 and 2022

General. The Company recorded a net loss of $4.5 million for the nine months ended September 30, 2023, compared to net income of $1.8 million for the nine months ended September 30, 2022.

Interest Income. For the nine months ended September 30, 2023 and 2022, interest income totaled $58.8 million and $44.8 million, respectively. This represents an increase of $13.9 million, or 31.1%, driven primarily by increases in rates earned on interest-earning assets and an increase in the average balance of loans of $198.9 million. The yield on average interest-earning assets was 3.91% and 3.18% for the nine months ended September 30, 2023 and 2022, respectively, an increase of 73 basis points from the prior period.

Interest Expense. For the nine months ended September 30, 2023, interest expense increased $20.1 million to $26.0 million when compared to the 2022 period due primarily to increases in rates paid on interest-bearing liabilities and an increase in the average balance of FHLB advances. FHLB advances for the nine months ended September 30, 2023 averaged $395.8 million as the Company borrowed to fund loan growth and to replace deposit outflows. Average deposit balances decreased $5.2 million when compared to the 2022 period. The cost of average interest-bearing liabilities increased 160 basis points to 2.15% for the nine months ended September 30, 2023 from 0.55% for the same period in 2022.

Net Interest Income. Net interest income was $32.7 million for the nine months ended September 30, 2023 compared to $38.9 million for the nine months ended September 30, 2022, a $6.2 million decrease. Net interest spread was 1.76% for the nine months ended September 30, 2023 compared to 2.64%, a decrease of 88 basis points. For the nine months ended September 30, 2023 and 2022, the net interest margin was 2.18% and 2.76%, respectively, a decrease of 58 basis points.

Provision for Credit Losses. The Company recorded a release of provision for credit losses totaling $597 thousand for the nine months ended September 30, 2023 and a release of provision for loan losses of $777 thousand for the same period in 2022. The release of provision on commitments and letters of credit, loans and securities totaled $443 thousand, $152 thousand and $2 thousand, respectively, for the nine months ended September 30, 2023.

Non-interest Income. For the nine months ended September 30, 2023 and 2022, non-interest income was $1.2 million and $2.2 million, respectively. The decrease of $987 thousand, or 44.5%, was primarily due to the reduction in prepayment fees of $758 thousand. In addition, there were no overdraft fees for the nine months ended September 30, 2023, while these fees totaled $218 thousand for the same period in 2022.

Non-interest Expense. Non-interest expense totaled $39.0 million for the nine months ended September 30, 2023, a decrease of $885 thousand from the same period in 2022. Excluding the provision for commitments and letters of credit, which prior to January 1, 2023 was recorded in non-interest expense, non-interest expense decreased $993 thousand. The decrease was primarily driven by decreases in professional fees and advertising expenses of $889 thousand and $759 thousand, respectively, partially offset by increases of $494 thousand in occupancy and equipment expense, $179 thousand in data processing and $324 thousand in FDIC assessment.

Income Tax Expense. The Company’s current tax position reflects the previously established full valuation allowance on its deferred tax assets. At September 30, 2023, the valuation allowance on deferred tax assets was $23.1 million. The Company did not record a tax benefit for the loss incurred during the year to date period because a full valuation allowance was required on its deferred tax assets. The effective tax rate for the first nine months of 2022 was 8.7% and was the result of the taxable income produced during the nine months ended September 30, 2022, partially offset by the ability to utilize a portion of the net operating losses that were fully reserved.

Total Deposits. Total deposits were $1.25 billion at September 30, 2023, a decrease of $35.8 million, or 2.77%, from December 31, 2022. Checking and savings accounts decreased $191.9 million, or 22.0%, to $680.7 million at September 30, 2023 from $872.6 million at December 31, 2022. This decrease was partially offset by an increase in time deposits of $156.1 million, or 37.5%, to $572.4 million at September 30, 2023 from $416.3 million at December 31, 2022. The increase in time deposits includes $50.0 million of brokered deposits. Uninsured and uncollateralized deposits to third party customers were $127.3 million, or 10% of total deposits, at the end of the quarter.

The following table presents the totals of deposit accounts by account type, at the dates shown below:

Borrowings. The Company had $402.5 million of borrowings at September 30, 2023, an increase of $92.0 million, or 29.6% from $310.5 million at December 31, 2022. Borrowings consist solely of Federal Home Loan Bank of New York advances.

Total Shareholders’ Equity. Total shareholders’ equity decreased by $34.6 million, or 8.8%, to $359.1 million at September 30, 2023 compared to $393.7 million at December 31, 2022. The decrease was primarily driven by the repurchase of treasury shares. The Company repurchased approximately 3.06 million shares at a weighted average cost of $9.99 per share.

Off-Balance Sheet. To help manage our interest rate position, the Company had $259.0 million in interest rate hedges at September 30, 2023, with a weighted average duration of 3.4 years and a weighted average rate of 2.52%. This represents an increase of $150.0 million from December 31, 2022, when we had $109.0 million in interest rate hedges with a weighted average duration of 4.2 years and a weighted average rate of 3.15%. See Note 8, Derivatives and Hedging Activities, of Notes to Consolidated Financial Statements in “Item 1- Financial Statements.”

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Qualitative Analysis. Our most significant form of market risk is interest rate risk because, as a financial institution, the majority of our assets and liabilities are sensitive to changes in interest rates. Therefore, a principal part of our operations is to manage interest rate risk and limit the exposure of our balance sheet and results of operations to changes in market interest rates. Our ALCO/Investment Committee, which consists of members of management, is responsible for evaluating the interest rate risk inherent in our assets and liabilities, for determining the level of risk that is appropriate, given our business strategy, operating environment, capital, liquidity and performance objectives, and for managing this risk consistent with the policy and guidelines approved by our board of directors. We currently utilize a modeling program, on a quarterly basis, to evaluate our sensitivity to changing interest rates, given our business strategy, operating environment, capital, liquidity and performance objectives, and for managing this risk consistent with the guidelines approved by the board of directors.

We have sought to manage our interest rate risk in order to minimize the exposure of our earnings and capital to changes in interest rates. We have implemented the following strategies to manage our interest rate risk: growing target deposit accounts, such as small business accounts; utilizing our investment securities portfolio and interest rate swaps as part of our balance sheet asset and liability and interest rate risk management strategy to reduce the impact of movements in interest rates on net interest income and economic value of equity, which can create temporary valuation adjustments to equity in Accumulated Other Comprehensive Income; continuing the diversification of our loan portfolio by adding more commercial loans, which typically have shorter maturities and/or balloon payments.

48

By following these strategies, we believe that we are positioned to react to increases and decreases in market interest rates.

Other than cash flow hedging on interest expense, we generally do not engage in hedging activities such as engaging in futures or options, or investing in high-risk mortgage derivatives such as collateralized mortgage obligation residual interests, real estate mortgage investment conduit residual interests or stripped mortgage-backed securities.

The Company has entered into derivative financial instruments to reduce risk associated with interest rate volatility by matching asset maturities and liability maturities. These derivatives had an aggregate notional amount of $259.0 million as of September 30, 2023.

Quantitative Analysis. We compute amounts by which the net present value of our cash flow from assets, liabilities and off-balance-sheet items would change in the event of a range of assumed changes in market interest rates. The economic value of equity (“EVE”) analysis estimates the change in the net present value (“NPV”) of assets and liabilities and off-balance-sheet contracts over a range of immediate rate shock interest rate scenarios. This model uses a discounted cash flow analysis and an option-based pricing approach to measure the interest rate sensitivity of net portfolio value. The model estimates the economic value of each type of asset, liability and off-balance-sheet contract under the assumption that the United States Treasury yield curve increases or decreases instantaneously by 100 to 200 basis points in 100 basis point increments. A basis point equals one-hundredth of one percent, and 100 basis points equals one percent. An increase in interest rates from 3% to 4% would mean, for example, a 100-basis point increase in the “Basis Point Change in Interest Rates” column below.

The following table sets forth, at September 30, 2023, the calculation of the estimated changes to the Bank’s net interest income, at the Bank level, that would result from the specified immediate changes in the United States Treasury yield curve. For purposes of this table, 100 basis points equals 1%.

	Net Interest Income
Change in Interest Rates (basis points)	Amount		Change		Percent
	(Dollars in Thousands)
+200	$	48,138	$	(587)	(1.2)	%
+100	48,436		(289)		(0.6)
0	48,725		—		—
-100	50,085		1,360		2.8
-200	50,268		1,543		3.2

The following table sets forth, at September 30, 2023, the calculation of the estimated changes in our net portfolio value, at the Bank level, that would result from the specified immediate changes in the United States Treasury yield curve. For purposes of this table, 100 basis points equals 1%.

	EVE						NPV as a Percent of Portfolio Value of Assets
Change in Interest Rates (basis points)	Estimated EVE		Estimated Increase (Decrease)
			Amount		Percent		NPV Ratio		Change
	(Dollars in thousands)
+200	$	7,890	$	(76,453)	(90.7)	%	0.4	%	(3.7)
+100	45,245		(39,098)		(46.4)		2.2		(1.9)
0	84,343		—		—		4.1		—
-100	123,910		39,567		46.9		6.0		1.9
-200	163,183		78,841		93.5		7.9		3.8

The tables above indicates that at September 30, 2023, in the event of an instantaneous 100 basis point increase in interest rates, we would experience a 46% decrease in EVE. In the event of an instantaneous 100 basis point decrease in interest rates, we would experience a 47% increase in EVE.

49

Certain short comings are inherent in the methodologies used in the above interest rate risk measurements. Modeling changes require making certain assumptions that may or may not reflect the manner in which actual yields and costs respond to changes in market interest rates. The above tables assume that the composition of our interest sensitive assets and liabilities existing at the date indicated remains constant uniformly across the yield curve regardless of the duration or repricing of specific assets and liabilities. Accordingly, although the table provides an indication of our interest rate risk exposure at a particular point in time, the data does not reflect any actions we may take in response to changes in interest rates. In addition, such measurements are not intended to and do not provide a precise forecast of the effect of changes in market interest rates on our NPV and will differ from actual results.

Liquidity and Capital Resources

Liquidity is the ability to meet current and future financial obligations of a short-term and long-term nature. Our primary sources of funds consist of deposit inflows, loan repayments, maturities and sales of securities, borrowings from the Federal Home Loan Bank of New York and securities sold under agreements to repurchase. While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit flows, calls of investment securities and borrowed funds and prepayments on loans are greatly influenced by general interest rates, economic conditions and competition.

Management regularly adjusts our investments in liquid assets based upon an assessment of (1) expected loan demand, (2) expected deposit flows, (3) yields available on interest-earning deposits and securities, and (4) the objectives of our interest-rate risk and investment policies.

At September 30, 2023, we had no commitments to originate loans and unused lines of credit totaled $107.7 million. We anticipate that we will have sufficient funds available to meet our current loan origination and lines of credit commitments. Certificates of deposit that are scheduled to mature in less than one year from September 30, 2023 totaled $536.0 million. Management expects, based on historical experience, that a deposit relationship will be retained with a substantial portion of certificate holders. However, if a substantial portion of these deposits is not retained, we may utilize Federal Home Loan Bank of New York advances or raise interest rates on deposits to attract new accounts, which may result in higher levels of interest expense. Available borrowing capacity at September 30, 2023 was $343.6 million with Federal Home Loan Bank of New York, a $30.0 million line of credit with a correspondent bank and a $2.5 million line of credit with the Federal Reserve Bank of New York. Total available borrowing capacity is 3.0 times total uninsured and uncollateralized deposits to third-party customers. The estimated fair market value of unencumbered securities totaled $305.8 million or 98.1% of the portfolio at September 30, 2023.

We are a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to originate loans, unused lines of credit and standby letters of credit, which involve elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. Our exposure to credit loss is represented by the contractual amount of the instruments. We use the same credit policies in making commitments that we do for on-balance sheet instruments. Management believes that our current sources of liquidity are more than sufficient to fulfill our obligations as of September 30, 2023 pursuant to off-balance-sheet arrangements and contractual obligations.

Principles of Consolidation: The accompanying consolidated financial statements include the accounts of Blue Foundry Bancorp (the “Company”), 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., and Blue Foundry Investment Company (collectively, the “Company”). All 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.

Shares of the Company’s common stock began trading on July 16, 2021 on the Nasdaq Global Select Market under the trading symbol “BLFY.”

Segment Reporting: The Company operates as a single operating segment for financial reporting purposes.

Basis of Financial Statement Presentation: The consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles. Certain information and note disclosures usually included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for the preparation of the Quarterly Reports on Form 10-Q and with Regulation S-X. 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 consolidated balance sheets and the consolidated statements of income 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 consolidated balance sheets and revenues and expenses for the period. Actual results could differ from those estimates. Some items in the prior year financial statements may be 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, 2023 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 the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed on March 30, 2023.

The accounting policies of the Company conform to U.S. GAAP and to general practice within the financial services industry. A discussion of these policies can be found in Note 1, Summary of Significant Accounting Policies, included in the Company’s 2022 Annual Report on Form 10-K. Except for the below, there have been no changes to the Company’s significant accounting policies since December 31, 2022.

Adoption of New Accounting Standards: The Company adopted Accounting Standards Update (“ASU”) 2020-04, “Reference Rate Reform (“ASU 2020-04”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts and hedging relationships, subject to meeting certain criteria, that reference the London Inter-Bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance was effective for all entities as of March 12, 2020 through December 31, 2022. However, in December 2022, the FASB issued ASU 2022-06, deferring the sunset date to December 31, 2024. The Company has evaluated the regulatory requirements to cease the use of LIBOR and has put in place systems and capabilities for this purpose. The adoption did not have a material impact on the Company’s consolidated financial statements.

The Company adopted ASU No. 2016-13, “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments,” which replaces the incurred loss model for loans and other financial assets with an expected loss model and is referred to as the current expected credit loss (“CECL”) model. The Company adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and off-balance-sheet credit exposures. The adoption of the new standard resulted in the Company recording an increase in the allowances for credit losses of $18 thousand, comprised of an increase of $660 thousand on loans, establishing a $170 thousand reserve on held-to-maturity securities and a reversal in the reserve for commitments and letters of credit of $811 thousand. There was no allowance for credit losses required on available-for-sale securities. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loans receivable and held-to maturity debt securities. It also applies to off-balance-sheet credit exposures (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 ASU 2016-13 require credit losses on available-for-sale securities to be presented as a valuation allowance rather than a direct write-down on the basis of the securities. Results for reporting periods beginning after January 1, 2023, are presented under CECL, while prior period amounts continue to be presented under previously-applied U.S. GAAP.

Loans

Under the CECL model, the allowance for credit losses on financial assets is a valuation allowance estimated at each balance sheet date in accordance with U.S. GAAP, and is deducted from the financial assets’ amortized cost basis to present the net amount expected to be collected on the financial assets.

The Company estimates the allowance for credit losses on loans based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for applicable accretion or amortization of premium, discount, net deferred fees or costs, collection of cash, and charge-offs. In the event that collection of principal becomes uncertain, the Company has policies in place to write-off accrued interest receivable by reversing interest income in a timely manner. Therefore, the Company has made a policy election to exclude accrued interest from the amortized cost basis and therefore excludes it from the measurement of the allowance for credit loss.

Changes in expected credit losses are reflected through a charge to the provision for credit losses. The Company’s estimate of the allowance for credit loss reflects losses expected over the remaining contractual life of the assets. When the Company deems all or a portion of a financial asset to be uncollectible, the appropriate amount is written off and the allowance for credit losses is reduced by the same amount. The Company applies judgment to determine when a financial asset is deemed uncollectible. When available information confirms that specific loans, securities, other assets, or portions thereof, are uncollectible, these amounts are charged-off against the allowance for credit losses. Subsequent recoveries, if any, are credited to the allowance for credit losses when received.

The Company measures expected credit losses of financial assets on a collective portfolio segment basis when the financial assets share similar risk characteristics. The Company generally measures expected credit losses using discounted cash flows (“DCF”) models at the portfolio segment level, whereby the total shortfall in comparing the portfolio segment DCFs to the amortized cost basis reflects management’s estimate of expected credit losses.

Our CECL models for loans includes the following major items:

–a historical loss period, which represents a full economic credit cycle utilizing loss experience including peer bank historical loss data, to calculate probabilities of default at the portfolio segment level;

–macroeconomic variable forecasts, including the national housing price index, unemployment and gross domestic product, to adjust probabilities of default over a reasonable and supportable forecast period of one year, based on management’s current review of the reliability of extended forecasts;

–a reversion period of one year to adjust probabilities of default (after the reasonable and supportable forecast period) to historical means using a straight-line approach;

–a risk index that measures loss given defaults as a function of probabilities of default at the portfolio segment level;

–expected prepayment rates based on our historical experience and benchmark assumptions where internal data is limited; and

–incorporation of qualitative factors not captured within the modeled results.

For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable and where the borrower is experiencing financial difficulty, the allowance for credit loss is measured based on the difference between the fair value of the collateral and the amortized cost basis of the asset as of the measurement date. Fair value is calculated based on the value of the underlying collateral less an appraisal discount and the estimated cost to sell.

Off-Balance-Sheet Exposures

The Company records changes in the allowance for credit losses on off-balance-sheet credit exposures through a charge to provision for credit losses. The allowance for credit loss on off-balance-sheet credit exposures is estimated by portfolio segment at each balance sheet date under the CECL model using the same methodologies as portfolio loans, taking into consideration management’s assumption of the likelihood that funding will occur, and is included in other liabilities on the Company’s consolidated balance sheets.

Securities

For securities available-for-sale, ASU 2016-13 eliminates the concept of other-than-temporary impairment and instead requires entities to determine if impairment is related to credit loss or non-credit loss. In making the assessment of whether a loss is from credit or other factors, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost basis, a credit loss exists and an allowance is created, limited by the amount that the fair value is less than the amortized cost basis.

The allowance for credit losses on held-to-maturity debt securities is initially recognized upon acquisition of the securities, and subsequently remeasured on a recurring basis. Expected credit losses on held-to-maturity debt securities through the life of the financial instrument are estimated and recognized as an allowance for credit losses on the balance sheet with a corresponding adjustment to current earnings. Subsequent favorable or unfavorable changes in expected cash flow will decrease or increase the allowance for credit losses through a charge to the provision for credit losses.

Management measures expected credit losses on held-to-maturity securities on a collective basis by major security type. The held-to-maturity portfolio is classified into the following major security types: corporate bonds and asset-backed securities.

At each reporting period, the Company evaluates whether the securities in a segment continue to exhibit similar risk characteristics as the other securities in the segment. If the risk characteristics of a security change, such that they are no longer similar to other securities in the segment, the Company will evaluate the security with a different segment that shares more similar risk characteristics.

The Company has a non-accrual policy that results in a timely reversal of interest receivable, therefore the Company made the election to exclude accrued interest receivable on securities from the estimate of credit losses.

In addition, the Company adopted ASU No. 2022-02, “Financial Instruments - Credit Losses (“ASU 2022-02”): Troubled Debt Restructurings (“TDR”) and Vintage Disclosures.” The amendments in this ASU were issued to (1) eliminate accounting guidance for TDRs by creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty; (2) require disclosures of current period gross write-offs by year of origination for financing receivables and net investments in leases. The amendments in this ASU were applied on a modified retrospective basis to recognize any change in the allowance for credit losses that had been recognized for receivables previously modified (or reasonably expected to be modified) in a TDR. This election resulted in a cumulative-effect adjustment to retained earnings as of January 1, 2023 of $8 thousand.

Accounting Standards Not Yet Adopted: As an “emerging growth company” as defined in Title 1 of the Jumpstart Our Business Startups (“JOBS”) Act, the Company elected to use the extended transition period to delay the adoption of new or reissued accounting pronouncements applicable to public companies until such pronouncements were made applicable to private companies.

Credit Quality Indicators

Credit ratings are a key measure for estimating the probability of a bond’s default and for monitoring credit quality on an on-going basis. For bonds other than U.S. Treasuries and bonds issued or guaranteed by U.S. government agencies, credit ratings issued by one or more nationally recognized statistical rating organization are considered in conjunction with an assessment by the Company’s management. Investment grade reflects a credit quality of BBB- or above. None of the Company’s securities are on non-accrual status, nor are any past due.

The table below indicates the credit profile of the Company’s debt securities held-to-maturity at amortized cost at September 30, 2023.

	AAA		A1		BBB+		BBB		BBB-		Total

Of the available-for-sale securities in an unrealized loss position at September 30, 2023, 66 are comprised of U.S. Government agency obligations, Treasury notes, and mortgage-backed securities. These securities were all issued by U.S. Government-sponsored entities and agencies, which the government has affirmed its commitment to support. Corporate bonds, obligations issued by U.S. states and their political subdivisions and asset-backed securities in an unrealized loss position all experienced a decline in fair value, which is attributable to changes in interest rates and liquidity, not credit quality. The Company also does not intend to sell these securities, nor does it foresee being required to sell them before the anticipated recovery or maturity.

LOANS RECEIVABLE

The Company adopted ASU 2016-13 on January 1, 2023. All disclosures as of September 30, 2023 are presented in accordance with ASU 2016-13. The Company did not reclassify comparative financial periods and has presented those disclosures under previously-applied U.S. GAAP.

(1) For more information, see Footnote 4 - Allowance for Credit Losses.

Loans are recorded at amortized cost, which includes principal balance, net deferred fees or costs, premiums and discounts. The Company elected to exclude accrued interest receivable from amortized cost. Accrued interest receivable is reported separately in the consolidated balance sheets and totaled $6.0 million and $5.3 million at September 30, 2023 and December 31, 2022, respectively. Loan origination fees and certain direct loan origination costs are deferred and the net fee or cost is recognized in interest income as an adjustment of yield. At September 30, 2023, net deferred loan fees are included in loans by respective segment and totaled $2.2 million.

The portfolio classes in the above table have unique risk characteristics with respect to credit quality:

•Payment on multifamily and non-residential mortgages is driven principally by operating results of the managed properties or underlying business and secondarily by the sale or refinance of such properties. Both primary and secondary sources of repayment and the value of the properties in liquidation, may be affected to a greater extent by adverse conditions in the real estate market or the economy in general.

•Properties underlying construction loans often do not generate sufficient cash flows to service debt and thus repayment is subject to the ability of the borrower and, if applicable, guarantors, to complete development or construction of the property and carry the project, often for extended periods of time. As a result, the performance of these loans is contingent upon future events whose probability at the time of origination is uncertain.

•Commercial and industrial (“C&I”) loans include C&I revolving lines of credit, term loans, SBA 7a loans and to a lesser extent, Paycheck Protection Program (“PPP”) loans. Payments on C&I loans are driven principally by the cash flows of the businesses and secondarily by the sale or refinance of any collateral securing the loans. Both the cash flow and value of the collateral in liquidation may be affected by adverse general economic conditions.

•The ability of borrowers to service debt in the residential one-to-four family, junior liens and consumer loan portfolios is generally subject to personal income which may be impacted by general economic conditions, such as increased unemployment levels. These loans are predominately collateralized by first and second liens on single family properties. If a borrower cannot maintain the loan, the Company’s ability to recover against the collateral in sufficient amount and in a timely manner may be significantly influenced by market, legal and regulatory conditions.

Credit Quality Indicators

The Company categorizes loans into risk categories based on relevant information about the quality and realizable value of collateral, if any, and the ability of borrowers to service their debts such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans by credit risk. This analysis is performed whenever credit is extended, renewed, or modified, or when an observable event occurs indicating a potential decline in credit quality, and no less than annually for large balance loans. The Company used the following definitions for risk ratings for loan classification:

Pass – Loans classified as pass are loans performing under the original contractual terms, do not currently pose any identified risk and can range from the highest to pass/watch quality, depending on the degree of potential risk.

Special Mention – Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or the Company’s credit position at some future date.

Substandard – Loans classified as substandard are inadequately protected by the current sound worth and paying capacity of the obligor, or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the repayment and liquidation of the debt. They are characterized by a distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

Doubtful – Loans classified as doubtful have all the weaknesses inherent in those classified as Substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions, and values, highly questionable and improbable.

Loss – Assets classified as loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted.  This classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off the asset even though partial recovery may be effected in the future.

The following table presents the risk category of loans by class of loan and vintage as of September 30, 2023:

The Company adopted ASU 2022-02 on January 1, 2023. Modifications made to borrowers experiencing financial difficulty may include principal forgiveness, interest rate reductions, other than insignificant payment delays, terms extensions or a combination thereof. At September 30, 2023, loans with modifications to borrowers experiencing financial difficulty totaled $5.5 million. These loans included one construction loan of $3.5 million and one residential loan of $374 thousand related to term extensions and two residential loans of $1.6 million related to other than insignificant payment delays. The Company did not reclassify comparative financial periods and has presented those disclosures under previously-applied U.S. GAAP.

Prior to the adoption of ASU 2022-02, the Company classified certain loans as troubled debt restructuring (“TDR”) loans when credit terms to a borrower in financial difficulty were modified in accordance with ASC 310-40. The total recorded investment of loans whose terms were modified in TDRs was $4.8 million as of December 31, 2022. The Company allocated $27 thousand of specific reserves to TDR loans as of December 31, 2022. The modification of the terms of TDR loans may have included one or a combination of the following: a reduction of the stated interest rate of the loan, short-term deferral of payment, or an extension of the maturity date.

A TDR loan was considered to be in payment default once it is 90 days contractually past due under the modified terms. There were no TDRs for which there was a payment default within twelve months following the modification during the period ended September 30, 2022. There were no TDRs during the three months ended September 30, 2022 and TDRs totaled $453 thousand during the nine months ended September 30, 2022.

The Company had $3.8 million and $4.5 million in consumer mortgage loans secured by residential real estate properties for which foreclosure proceedings are in process at September 30, 2023 and December 31, 2022, respectively. At September 30, 2023, the Company had one one-to-four family loan with a carrying value of $593 thousand in real estate owned. There was no real estate owned at December 31, 2022.

ALLOWANCE FOR CREDIT LOSSES

Credit Loss [Abstract]

ALLOWANCE FOR CREDIT LOSSES

ALLOWANCE FOR CREDIT LOSSES

On January 1, 2023, the Company adopted ASU 2016-13, which requires the measurement of expected credit losses for financial assets measured at amortized cost, including loans, held-to-maturity securities and certain off-balance-sheet credit exposures and ASU 2022-02, which eliminates the recognition and measurement guidance of TDRs, so that creditors will apply the same guidance to all modifications when determining whether a modification results in a new receivable or continuation of an existing receivable. See Note 1 - Summary of Significant Accounting Policies for a description of the adoption of ASU 2016-13 and the Company’s allowance methodology.

Under ASU 2016-13, the Company’s methodology for determining the allowance for credit losses on loans is based upon key assumptions, including the lookback period, historical loss experience, economic forecasts over a reasonable and supportable forecast period, reversion period, prepayments and qualitative adjustments. The allowance is measured on a pool basis when similar risk characteristics exist. Loans that do not share common risk characteristics are evaluated on an individual basis and are excluded from the collective evaluation.

Allowance for Credit Losses - Loans

The allowance for credit losses on loans is summarized in the following table:

During the three and nine months ended September 30, 2023, one residential loan, that was originated in 2006, had a charge-off of $18 thousand. The loan was transferred to other real estate owned in the third quarter of 2023. Consumer and other charge-offs relate to overdrafts, which were originated in 2023, as it is our policy to charge these off within 60 days of occurrence.

Allowance for Credit Losses - Securities

The Company recorded an allowance of credit losses on securities of $170 thousand upon adoption of ASU 2016-13 on January 1, 2023. Prior year disclosures have not been restated. At September 30, 2023, the balance of the allowance of credit losses on securities was $168 thousand. For the three and nine months ended September 30, 2023, the Company recorded a decrease in provision for credit losses of $2 thousand on held-to-maturity securities. Accrued interest receivable on securities is reported as a component of accrued interest receivable on the consolidated balance sheets and totaled $1.8 million and $1.0 million at September 30, 2023 and December 31, 2022, respectively. The Company made the election to exclude accrued interest receivable from the estimate of credit losses on securities.

Allowance for Credit Losses - Off-Balance-Sheet Exposures

The allowance for credit losses on off-balance-sheet exposures is reported in other liabilities in the consolidated balance sheets. The liability represents an estimate of expected credit losses arising from off-balance-sheet exposures such as letters of credit, guarantees and unfunded loan commitments. The process for measuring lifetime expected credit losses on these exposures is consistent with that for loans as discussed above, but is subject to an additional estimate reflecting the likelihood that funding will occur. No liability is recognized for off-balance-sheet credit exposures that are unconditionally cancellable by the Company. Adjustments to the liability are reported as a component of provision for credit losses.

The Company recorded a decrease in the allowance for credit losses for off-balance-sheet exposures of $811 thousand upon adoption on January 1, 2023. Prior year disclosures have not been restated. At September 30, 2023 and December 31, 2022, the balance of the allowance for credit losses for off-balance-sheet exposures was $435 thousand and $1.7 million, respectively. The Company recorded a recovery of provision for credit loss on off-balance-sheet exposures of $201 thousand and $443 thousand for the three and nine months ended September 30, 2023, respectively. For the three and nine months ended September 30, 2022, the Company recorded a provision on unfunded lending commitments of $170 thousand and a recovery of $108 thousand, respectively, in other non-interest expense.

The Company maintains an ESOP, a tax-qualified plan designed to invest primarily in the Company’s common stock. The ESOP provides employees with the opportunity to receive a funded retirement benefit from the Bank, based primarily on the value of the Company’s common stock.

The ESOP borrowed funds from the Company to purchase 2,281,800 shares of stock at $10 per share. The loan is secured by the shares purchased, which are held until allocated to participants. Shares are released for allocation to participants as loan payments are made. Loan payments are principally funded by discretionary cash contributions by the Bank, as well as dividends, if any, paid to the ESOP on unallocated shares. When loan payments are made, ESOP shares are allocated to participants at the end of the plan year (December 31) based on relative compensation, subject to federal tax law limits. Participants receive the allocated vested shares at the end of employment. Dividends on allocated shares, if any, increase participants accounts.

At September 30, 2023, the principal balance on the ESOP loan was $21.2 million. There were no contributions to the ESOP during the three and nine months ended September 30, 2023, as loan payments are made annually during the fourth quarter of each year. ESOP shares are committed to be released from unallocated and compensation expense is recognized over the service period. At September 30, 2023 and December 31, 2022, there were 2,099,256 unallocated shares and 182,544 shares allocated to participants. The fair value of unallocated shares at September 30, 2023 and December 31, 2022 was $17.6 million and $27.0 million, respectively, computed using the closing trading price of the Company’s common stock on each date.

For the three and nine months ended September 30, 2023, ESOP compensation expense for the shares committed to be released from unallocated was $216 thousand and $699 thousand respectively. Shares committed to be released from unallocated total 22,818 and 68,454 for the three and nine months ended September 30, 2022, respectively. During the three and nine months ended September 30, 2022, the Company recorded $266 thousand and $870 thousand, respectively, of ESOP compensation expense.

Equity Incentive Plan

At the annual meeting held on August 25, 2022, stockholders of the Company approved the Blue Foundry Bancorp 2022 Equity Incentive Plan (“Equity Plan”) which provides for the granting of up to 3,993,150 shares (1,140,900 restricted stock awards and 2,852,250 stock options) of the Company’s common stock.

Restricted shares granted under the Equity Plan generally vest in equal installments, over a service period between five and seven years beginning one year from the date of grant. Additionally, certain restricted shares awarded can be performance vesting awards, which may or may not vest depending upon the attainment of certain corporate financial targets. The vesting of the awards accelerate upon death, disability or an involuntary termination at or following a change in control. The product of the number of shares granted and the grant date closing market price of the Company’s common stock determine the fair value of restricted shares under the Equity Plan. Management recognizes compensation expense for the fair value of restricted shares on a straight-line basis over the requisite service period.

Stock options granted under the Equity Plan generally vest in equal installments, over a service period between five and seven years beginning one year from the date of grant. The vesting of the options accelerate upon death, disability or an involuntary termination at or following a change in control. Stock options were granted at an exercise price equal to the fair value of the Company’s common stock on the grant date based on the closing market price and have an expiration period of ten years.

There were no stock options granted during the nine months ended September 30, 2023. The fair value of stock options granted during 2022 were estimated utilizing the Black-Scholes option pricing model using the following assumptions: an expected life of 6.5 years, risk-free rate of 3.15%, volatility of 29.74% and a dividend yield of 0.88%. Due to the limited historical information of the Company’s stock, management considered the weighted historical volatility of the Company and similar entities for an appropriate period in determining the volatility rate used in the estimation of fair value. The expected life of the stock option was estimated using the simplified method. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The Company recognizes compensation expense for the fair values of these awards, which have straight-line vesting, on a straight-line basis over the requisite service period of the awards. Upon exercise of vested options, management expects to draw on treasury stock as the source for shares.

The following table presents the share-based compensation expense for the three and nine months ended September 30, 2023 and 2022.

Expected future expense relating to the non-vested options outstanding as of September 30, 2023 is $8.6 million over a weighted average period of 5.5 years.

On March 6, 2023, the Company granted to employees, under the 2022 Equity Incentive Plan, 372,540 restricted stock awards with a total grant-date fair value of $4.5 million. Of these grants, 12,300 vest one year from the date of grant and 360,240 vest in equal installments over a seven-year period beginning one year from the date of grant. The Company also issued 360,240 performance-based restricted stock awards to its officers with a total grant date fair value of $4.3 million. Vesting of the performance-based restricted stock units will be based on achievement of certain levels of loan growth, deposit growth and net interest margin and will convert to a seven-year time vest after the one-year measurement period ending December 31, 2023. At the end of the performance period, the number of actual shares to be awarded may vary between 0% and 100% of target amounts.

The following is a summary of the status of the Company’s restricted shares as of September 30, 2023 and changes therein during the nine months ended:

DERIVATIVES AND HEDGING ACTIVITIES

DERIVATIVES AND HEDGING ACTIVITIES

The Company utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. The notional amount of the interest rate swaps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements.

The Company had interest rate swaps with notional amounts totaling $259.0 million and $109.0 million at September 30, 2023 and December 31, 2022, respectively. As of September 30, 2023, they were designated as cash flow hedges of certain Federal Home Loan Bank (“FHLB”) advances and brokered deposits and, as of December 31, 2022, they were designated as cash flow hedges of certain Federal Home Loan Bank (“FHLB”) advances. They were determined to be highly effective during all periods presented. The Company expects the hedges to remain highly effective during the remaining terms of the swaps.

Summary information about the interest rate swaps designated as cash flow hedges as of period-end is as follows:

	September 30, 2023			December 31, 2022

Gross unrealized loss included in other liabilities	—			—
Unrealized gains, net	$	14,350		$	11,091

At September 30, 2023, the Company held $15.3 million as cash collateral pledged from the counterparty for these interest-rate swaps and had no securities pledged to the counterparty. At December 31, 2022, the Company held $11.5 million as cash collateral pledged from the counterparty and had no securities pledged to the counterparty.

Interest income or expense recorded on these swap transactions is reported as a component of interest expense on FHLB advances or brokered deposits. Interest income during the three months ended September 30, 2023 totaled $1.5 million and interest income for the three months ended September 30, 2022 totaled $198 thousand. Interest income during the nine months ended September 30, 2023 totaled $3.9 million and interest expense for the nine months ended September 30, 2022 totaled $270 thousand. At September 30, 2023, the Company expected $1.8 million of the unrealized gain to be reclassified as a reduction to interest expense during the remainder of 2023.

FAIR VALUE OF ASSETS AND LIABILITIES

9 Months Ended

Fair Value Disclosures [Abstract]

FAIR VALUE OF ASSETS AND LIABILITIES

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 Company used the following methods and significant assumptions to estimate fair value:

Securities: For securities available-for-sale, fair value was estimated using a market approach. The majority of the Company’s securities are fixed income instruments that are not quoted on an exchange, but are traded in active markets. Prices for these instruments are obtained through third party data service providers or dealer market participants with which the Company has historically transacted both purchases and sales of securities. Prices obtained from these sources include market quotations and matrix pricing. Matrix pricing, a Level 2 input as defined by ASC 820, is a mathematical technique used principally to value certain securities to benchmark or comparable securities. The Company evaluates the quality of Level 2 matrix pricing through comparison to similar assets with greater liquidity and evaluation of projected cash flows. The Company also holds debt instruments issued by the U.S. government and U.S. government sponsored agencies that are traded in active markets with readily accessible quoted market prices that are considered Level 1 inputs.

Derivatives: The fair values of derivatives are based on valuation models using observable market data as of the measurement date (Level 2). The Company’s derivatives are traded in an over-the-counter market where quoted market prices are not always available. Therefore, the fair values of derivatives are determined using quantitative models that utilize multiple market inputs. The inputs will vary based on the type of derivative, but could include interest rates, prices and indices to generate continuous yield or pricing curves, prepayment rates and volatility factors to value the position. The majority of market inputs are actively quoted and can be validated through external sources, including brokers, market transactions and third-party pricing services.

Impaired loans: The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value.

Other real estate owned (OREO): Property acquired through foreclosure or deed in lieu of foreclosure is carried at fair value less estimated disposal costs of the acquired property. Fair value of OREO is based on the appraised value of the collateral using discount rates similar to those used in impaired loan valuation.

Assets held for sale: Nonrecurring adjustments to certain non-residential properties classified as assets held for sale are measured at fair value, less costs to sell. Fair values are based on contracts or letters of intent.

The following table summarizes the fair value of assets and liabilities as of September 30, 2023:

Other Fair Value Disclosures

Fair value estimates, methods and assumptions for the Company’s financial instruments that are not recorded at fair value on a recurring or non-recurring basis are set forth below.

Securities held-to-maturity: The Company’s debt securities held-to-maturity portfolio is carried at amortized cost less allowance for credit losses. The fair values of debt securities held-to-maturity are provided by a third-party pricing service. The pricing service may use quoted market prices of comparable instruments or a variety of other forms of analysis, incorporating inputs that are currently observable in the markets for similar securities. Inputs that are often used in the valuation methodologies include, but are not limited to, benchmark yields, credit spreads, default rates, prepayment speeds and non-binding broker quotes.

Loans, net: Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type, such as residential mortgage and consumer. Each loan category is further segmented into fixed and adjustable rate interest terms and by performing and non-performing categories. Estimated fair value of loans is determined using a discounted cash flow model that employs an exit discount rate that reflects the current market pricing for loans with similar characteristics and remaining maturity, adjusted for estimated credit losses inherent in the portfolio at the balance sheet date.

Time deposits: The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using rates for currently offered deposits of similar remaining maturities.

Federal Home Loan Bank advances: The fair value of borrowings is based on securities dealers’ estimated fair values, when available, or estimated using discounted cash flow analysis. The discount rates used approximate the rates offered for similar borrowings of similar remaining terms.

The following tables present the book value, fair value, and placement in the fair value hierarchy of financial instruments not recorded at fair values in their entirety on a recurring basis on the Company’s consolidated balance sheets at September 30, 2023 and December 31, 2022. The fair value measurements presented are consistent with Topic 820, Fair Value Measurement, in which fair value represents exit price. These tables exclude financial instruments for which the carrying amount approximates fair value. Financial instruments for which the carrying amount approximates fair value include cash and cash equivalents, other investments, non-maturity deposits, overnight borrowings and accrued interest, which are excluded from the table below.

Revenue from Contract with Customer [Abstract]

REVENUE FROM CONTRACTS WITH CUSTOMERS AND OTHER INCOME

REVENUE FROM CONTRACTS WITH CUSTOMERS AND OTHER INCOME

All of the Company’s revenue from contracts with customers in the scope of ASC 606 is recognized within non-interest income in the statements of income.

The following table presents the Company’s sources of revenue from contracts with customers for the three and nine months ended September 30, 2023 and 2022, respectively:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
	(In thousands)
Service charges on deposits	$	205	$	255	$	636	$	752
Interchange income	13		12		38		31
Total revenue from contracts with customers	$	218	$	267	$	674	$	783

Service Charges on Deposit Accounts: The Company earns fees from its deposit customers for transaction-based, account maintenance and, prior to November 1, 2022, overdraft services. Transaction based fees, which include services such as ATM use fees, stop payment charges, statement rendering and wire transfer fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. When they were assessed, overdraft fees were recognized at the point in time the overdraft occurred. Service charges on deposits are withdrawn from the customer’s account balance.

Interchange Income: The Company earns interchange fees from debit cardholder transactions conducted through a payment network. Interchange fees from debit cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. In addition, the Company earns interchange fees from credit cardholder transactions through its partnership with a third party.

Earnings Per Share [Abstract]

EARNINGS PER SHARE

EARNINGS PER SHARE

Basic earnings per share (“EPS”) represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common shares (such as unexercised stock options and unvested restricted stock) were exercised or converted into additional common shares that would then share in the earnings of the entity. Diluted EPS is computed by dividing net income attributable to common shareholders by the weighted-average number of common shares outstanding for the period, plus the effect of potential dilutive common share equivalents.

Shares held by the Employee Stock Ownership Plan (“ESOP”) that have not been allocated to employees in accordance with the terms of the ESOP, referred to as “unallocated ESOP shares,” are not deemed outstanding for earnings per share calculations.

Excluded from the earnings per share calculation are anti-dilutive equity awards for the three and nine months ended September 30, 2023, totaling 1,496,475 and 1,278,351, respectively. For the three and nine months ended September 30, 2022, anti-dilutive equity awards totaling 98,000 and 33,000, respectively, were excluded from the earnings per share calculation. Due to the Company’s net loss for the three and nine months ended September 30, 2023, the assumed vesting of outstanding restricted stock units had an antidilutive effect on diluted earnings per share.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

9 Months Ended

Sep. 30, 2023

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation: The accompanying consolidated financial statements include the accounts of Blue Foundry Bancorp (the “Company”), 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., and Blue Foundry Investment Company (collectively, the “Company”). All intercompany accounts and transactions have been eliminated in consolidation. Blue Foundry Bancorp owns 100% of the common stock of Blue Foundry Bank.

Segment Reporting

Segment Reporting: The Company operates as a single operating segment for financial reporting purposes.

Basis of Financial Statement Presentation

Basis of Financial Statement Presentation: The consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles. Certain information and note disclosures usually included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for the preparation of the Quarterly Reports on Form 10-Q and with Regulation S-X. 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 consolidated balance sheets and the consolidated statements of income 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 consolidated balance sheets and revenues and expenses for the period. Actual results could differ from those estimates. Some items in the prior year financial statements may be 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, 2023 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 the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed on March 30, 2023.

The accounting policies of the Company conform to U.S. GAAP and to general practice within the financial services industry. A discussion of these policies can be found in Note 1, Summary of Significant Accounting Policies, included in the Company’s 2022 Annual Report on Form 10-K. Except for the below, there have been no changes to the Company’s significant accounting policies since December 31, 2022.

Adoption of New Accounting Standards and Accounting Standards Not Yet Adopted

Adoption of New Accounting Standards: The Company adopted Accounting Standards Update (“ASU”) 2020-04, “Reference Rate Reform (“ASU 2020-04”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts and hedging relationships, subject to meeting certain criteria, that reference the London Inter-Bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance was effective for all entities as of March 12, 2020 through December 31, 2022. However, in December 2022, the FASB issued ASU 2022-06, deferring the sunset date to December 31, 2024. The Company has evaluated the regulatory requirements to cease the use of LIBOR and has put in place systems and capabilities for this purpose. The adoption did not have a material impact on the Company’s consolidated financial statements.

The Company adopted ASU No. 2016-13, “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments,” which replaces the incurred loss model for loans and other financial assets with an expected loss model and is referred to as the current expected credit loss (“CECL”) model. The Company adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost and off-balance-sheet credit exposures. The adoption of the new standard resulted in the Company recording an increase in the allowances for credit losses of $18 thousand, comprised of an increase of $660 thousand on loans, establishing a $170 thousand reserve on held-to-maturity securities and a reversal in the reserve for commitments and letters of credit of $811 thousand. There was no allowance for credit losses required on available-for-sale securities. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loans receivable and held-to maturity debt securities. It also applies to off-balance-sheet credit exposures (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 ASU 2016-13 require credit losses on available-for-sale securities to be presented as a valuation allowance rather than a direct write-down on the basis of the securities. Results for reporting periods beginning after January 1, 2023, are presented under CECL, while prior period amounts continue to be presented under previously-applied U.S. GAAP.

Loans

Under the CECL model, the allowance for credit losses on financial assets is a valuation allowance estimated at each balance sheet date in accordance with U.S. GAAP, and is deducted from the financial assets’ amortized cost basis to present the net amount expected to be collected on the financial assets.

The Company estimates the allowance for credit losses on loans based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for applicable accretion or amortization of premium, discount, net deferred fees or costs, collection of cash, and charge-offs. In the event that collection of principal becomes uncertain, the Company has policies in place to write-off accrued interest receivable by reversing interest income in a timely manner. Therefore, the Company has made a policy election to exclude accrued interest from the amortized cost basis and therefore excludes it from the measurement of the allowance for credit loss.

Changes in expected credit losses are reflected through a charge to the provision for credit losses. The Company’s estimate of the allowance for credit loss reflects losses expected over the remaining contractual life of the assets. When the Company deems all or a portion of a financial asset to be uncollectible, the appropriate amount is written off and the allowance for credit losses is reduced by the same amount. The Company applies judgment to determine when a financial asset is deemed uncollectible. When available information confirms that specific loans, securities, other assets, or portions thereof, are uncollectible, these amounts are charged-off against the allowance for credit losses. Subsequent recoveries, if any, are credited to the allowance for credit losses when received.

The Company measures expected credit losses of financial assets on a collective portfolio segment basis when the financial assets share similar risk characteristics. The Company generally measures expected credit losses using discounted cash flows (“DCF”) models at the portfolio segment level, whereby the total shortfall in comparing the portfolio segment DCFs to the amortized cost basis reflects management’s estimate of expected credit losses.

Our CECL models for loans includes the following major items:

–a historical loss period, which represents a full economic credit cycle utilizing loss experience including peer bank historical loss data, to calculate probabilities of default at the portfolio segment level;

–macroeconomic variable forecasts, including the national housing price index, unemployment and gross domestic product, to adjust probabilities of default over a reasonable and supportable forecast period of one year, based on management’s current review of the reliability of extended forecasts;

–a reversion period of one year to adjust probabilities of default (after the reasonable and supportable forecast period) to historical means using a straight-line approach;

–a risk index that measures loss given defaults as a function of probabilities of default at the portfolio segment level;

–expected prepayment rates based on our historical experience and benchmark assumptions where internal data is limited; and

–incorporation of qualitative factors not captured within the modeled results.

For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable and where the borrower is experiencing financial difficulty, the allowance for credit loss is measured based on the difference between the fair value of the collateral and the amortized cost basis of the asset as of the measurement date. Fair value is calculated based on the value of the underlying collateral less an appraisal discount and the estimated cost to sell.

Off-Balance-Sheet Exposures

The Company records changes in the allowance for credit losses on off-balance-sheet credit exposures through a charge to provision for credit losses. The allowance for credit loss on off-balance-sheet credit exposures is estimated by portfolio segment at each balance sheet date under the CECL model using the same methodologies as portfolio loans, taking into consideration management’s assumption of the likelihood that funding will occur, and is included in other liabilities on the Company’s consolidated balance sheets.

Securities

For securities available-for-sale, ASU 2016-13 eliminates the concept of other-than-temporary impairment and instead requires entities to determine if impairment is related to credit loss or non-credit loss. In making the assessment of whether a loss is from credit or other factors, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost basis, a credit loss exists and an allowance is created, limited by the amount that the fair value is less than the amortized cost basis.

The allowance for credit losses on held-to-maturity debt securities is initially recognized upon acquisition of the securities, and subsequently remeasured on a recurring basis. Expected credit losses on held-to-maturity debt securities through the life of the financial instrument are estimated and recognized as an allowance for credit losses on the balance sheet with a corresponding adjustment to current earnings. Subsequent favorable or unfavorable changes in expected cash flow will decrease or increase the allowance for credit losses through a charge to the provision for credit losses.

Management measures expected credit losses on held-to-maturity securities on a collective basis by major security type. The held-to-maturity portfolio is classified into the following major security types: corporate bonds and asset-backed securities.

At each reporting period, the Company evaluates whether the securities in a segment continue to exhibit similar risk characteristics as the other securities in the segment. If the risk characteristics of a security change, such that they are no longer similar to other securities in the segment, the Company will evaluate the security with a different segment that shares more similar risk characteristics.

The Company has a non-accrual policy that results in a timely reversal of interest receivable, therefore the Company made the election to exclude accrued interest receivable on securities from the estimate of credit losses.

In addition, the Company adopted ASU No. 2022-02, “Financial Instruments - Credit Losses (“ASU 2022-02”): Troubled Debt Restructurings (“TDR”) and Vintage Disclosures.” The amendments in this ASU were issued to (1) eliminate accounting guidance for TDRs by creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty; (2) require disclosures of current period gross write-offs by year of origination for financing receivables and net investments in leases. The amendments in this ASU were applied on a modified retrospective basis to recognize any change in the allowance for credit losses that had been recognized for receivables previously modified (or reasonably expected to be modified) in a TDR. This election resulted in a cumulative-effect adjustment to retained earnings as of January 1, 2023 of $8 thousand.

Accounting Standards Not Yet Adopted: As an “emerging growth company” as defined in Title 1 of the Jumpstart Our Business Startups (“JOBS”) Act, the Company elected to use the extended transition period to delay the adoption of new or reissued accounting pronouncements applicable to public companies until such pronouncements were made applicable to private companies.
