Principles of  Consolidation and Basis of Presentation

Within the accompanying unaudited interim consolidated financial statements and related notes to the consolidated financial statements, the June 30, 2023 data was derived from the audited consolidated financial statements and notes of Greene County Bancorp, Inc. (the “Company”) and its wholly owned subsidiaries, The Bank of Greene County (the “Bank”) and the Bank’s wholly owned subsidiaries, Greene County Commercial Bank (the “Commercial Bank”) and Greene Property Holdings, Ltd. The interim consolidated financial statements at and for the three and nine months ended March 31, 2024 and 2023 are unaudited.

The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X.  Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements.  To the extent that information and notes required by GAAP for complete financial statements are contained in or are consistent with the audited financial statements incorporated by reference to Greene County Bancorp, Inc.’s Annual Report on Form 10-K for the year ended June 30, 2023, such information and notes have not been duplicated herein. In the opinion of management, all adjustments (consisting of only normal recurring items) necessary for a fair presentation of the financial position and results of operations and cash flows at and for the periods presented have been included. Certain previous years’ amounts in the unaudited consolidated financial statements and notes thereto, have been reclassified to conform to the current year’s presentation.  All material inter-company accounts and transactions have been eliminated in the consolidation. The results of operations and other data for the three and nine months ended March 31, 2024 are not necessarily indicative of results that may be expected for the entire fiscal year ending June 30, 2024. These consolidated financial statements consider events that occurred through the date the consolidated financial statements were issued and should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K.

Nature of Operations

The Company’s primary business is the ownership and operation of its subsidiaries.  At March 31, 2024, the Bank has 18 full-service offices, lending centers, an operations center, customer call center, and wealth management center, located in its market area consisting of the Hudson Valley and Capital District Regions of New York State.  The Bank is primarily engaged in the business of attracting deposits from the general public in the Bank’s market area, and investing such deposits, together with other sources of funds, in loans and investment securities.  The Commercial Bank’s primary business is to attract deposits from, and provide banking services to, local municipalities.  Greene Property Holdings, Ltd. was formed as a New York corporation that has elected under the Internal Revenue Code to be a real estate investment trust.  Currently, certain mortgages and loan notes held by the Bank are transferred and beneficially owned by Greene Property Holdings, Ltd.  The Bank continues to service these loans.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could materially differ from those estimates.  Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for credit losses on loans and on unfunded commitments.

Interest-bearing deposits

At March 31, 2024, included within interest bearing deposits, is $23.2 million of restricted cash. The restriction is due to the surrender of bank owned life insurance during the quarter ended December 31, 2023.

Allowance for Credit Losses on Loans

The Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“CECL”) approach requires an estimate of the credit losses expected over the life of a loan (or pool of loans). The allowance is a valuation account that is deducted from, or added to, the loans’ amortized cost basis to present the net, lifetime amount expected to be collected on the loans. Loan losses are charged off against the allowance when management believes a loan balance is confirmed to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and amounts expected to be charged-off.

Collateral dependent loans that are on nonaccrual status, with a balance of $250,000 or greater are evaluated on an individual basis and excluded from the pooled loan evaluation. The fair value of collateral for collateral dependent loans less selling costs will be compared to the loan balance to determine if a CECL reserve is required. When management determines that foreclosure is probable, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs.

The loan portfolio is segmented based on the level at which the Company develops and documents a systematic methodology to determine its allowance for credit losses. Management developed the following segments for estimating loss based on type of borrower and collateral which is generally based upon federal call report segmentation and have been combined as needed to ensure loans of similar risk profiles are appropriately pooled: residential real estate, commercial real estate, consumer loan, home equity and commercial loans.

Management estimates the allowance for credit losses on loans by using relevant information, from internal and external sources, related to past events, current conditions, and reasonable and supportable forecasts that affect the collectability of loans. Historical loss experience was considered by the Company for estimating expected credit losses and determined the need to use peer data, with similar risk profiles, to develop and calculate the CECL reserve models.

Historical credit loss experience for the Company and peer losses by loan segments, provide a foundation for estimating an expected credit loss. The observed credit losses are converted to probability of default (“PD”) rate curves through the use of loss given default (“LGD”) risk factors that converts default rates to estimated loss for each loan segment. This is based on industry-level, observed relationships between the PD and LGD variables for each segment. The historical PD curves correspond to economic variables through historical economic cycles, which establishes a quantitative relationship between forecasted economic conditions and loan performance.

Using the historical quantitative relationship between economic conditions and loan performance, management developed a model, using selected external economic forecasts that is highly correlated for each loan segment. These forecasts are then applied over a period that management has determined to be reasonable and supportable. Beyond the period over which management can develop or source a reasonable and supportable forecast, the model will revert to long-term average economic conditions using a straight-line methodology.

The allowance for credit losses on loans is measured on a collective basis, when similar risk characteristics are present, with both a quantitative and qualitative analysis that is applied on a quarterly basis. The respective quantitative reserve for each segment is calculated using a PD/LGD modeling methodology, with segment-specific regression models. The discounted cash flows methodology uses expected credit losses estimated over the effective life of each loan by measuring the difference between the net present value of modeled cash flows and amortized cost basis. Contractual cash flows over the contractual life of the loans are the basis for modeled cash flows, adjusted for modeled defaults and expected prepayments and discounted at the loan-level stated interest rate.

Management applies a qualitative adjustment for each segment as of the balance sheet date. The qualitative adjustments include limitations inherent in the quantitative model; changes in lending policies and procedures; changes in international, national, regional, and local economic conditions; changes in the nature and volume of the portfolio and terms of loans; the experience, ability and depth of lending management and staff; changes in the volume and severity of past due loans; changes in value of underlying collateral; existence and effect of any concentrations of credit and changes in the levels of such concentrations; and the effect of external factors; such as competition, legal and regulatory requirements.

Allowance for Credit Losses on Unfunded Commitments

The Company estimates expected credit losses over the contractual period in which the Company has exposure to a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on unfunded commitments exposure is recognized in other liabilities and is adjusted as an expense in other noninterest expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over the estimated contractual life. The Company considers the following segments of unfunded commitments exposure; home equity line of credits, commercial line of credits, consumer loans, the residential and commercial real estate loans committed but not closed and the unfunded portion of the construction loans. The probable funding amount by segment is multiplied by the respective reserve percentage calculated in the allowance for credit losses on loans to calculate a reserve on unfunded commitments.

Allowance for Credit Losses on Securities Held-to-Maturity(“HTM”)

The Company is required to utilize the CECL approach to estimate expected credit losses. Management measures expected credit losses on HTM debt securities on a collective basis by major security types that share similar risk characteristics. Management classifies the HTM portfolio into the following major security types: U.S. Treasury securities, state and political subdivisions, mortgage-backed securities-residential, mortgage-backed securities-multi-family, corporate debt securities and other securities.

Expected losses are calculated on a pooled basis using a probability of default/loss given default(PD/LGD) model, based on historical credit loss data from a reliable source. Management utilizes municipal and corporate default and loss rates which provides decades of data across all municipal and corporate sectors and geographies. Management may exercise discretion to make adjustments based on environmental factors. The model calculates the expected loss for each security over the contractual life. If the risk of a held-to-maturity debt security no longer matches the collective assessment pool, it is removed and individually assessed for credit deterioration.

U.S. Treasury and mortgage-backed securities are issued by U.S. government entities and agencies. These securities are either explicitly and/or implicitly guaranteed by the U.S. government as to timely repayment of principal and interest, are highly rated by major rating agencies, and have a long history of zero credit losses. Therefore, the Company determined a zero credit loss assumption, and did not calculate or record an allowance for credit loss for these securities.

Allowance for Credit Losses on Securities Available-for-sale (“AFS”)

The credit loss model for AFS debt securities requires credit losses to be presented as an allowance rather than a direct write-down of debt securities. AFS debt securities continue to be recorded at fair value with changes in fair value reflected in other comprehensive income. When the fair value of an AFS debt security falls below the amortized cost basis it is evaluated to determine if any of the decline in value is attributable to credit loss. 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. The cash flows are estimated using information relevant to the collectability of the security, including information about past events, current conditions and reasonable and supportable forecasts. Decreases in fair value attributable to credit loss are recorded directly to earnings with a corresponding allowance for credit losses, limited to the amount that the fair value is less than the amortized cost basis. If the credit quality subsequently improves, the allowance is reversed up to a maximum of the previously recorded credit losses. When the Company intends to sell an impaired AFS debt security, or if it is more likely than not that the Company will be required to sell the security prior to recovering the amortized cost basis, the entire fair value adjustment will immediately be recognized in earnings with no corresponding allowance for credit losses.

Investments in Federal Home Loan Bank (“FHLB”) stock are required for membership and are carried at cost since there is no market value available. The FHLB New York continues to pay dividends and repurchase stock. As such, the Company has not recognized any credit loss on its holdings of FHLB stock.

Accrued Interest Receivable

Accrued interest receivable balances are presented separately on the consolidated statements of financial condition and are not included in amortized cost when determining the allowance for credit losses. Accrued interest receivable that is deemed uncollectible is written off timely. For loans, write off typically occurs upon becoming over 90 to 120 days past due and therefore the amount of such write offs are immaterial. Historically, the Company has not experienced uncollectible accrued interest receivable on investment securities.

Derivative Instruments

The Company enters into interest rate swap agreements that are not designated as hedges for accounting purposes. As the interest rate swap agreements have substantially equivalent and offsetting terms, they do not present any material exposure to the Company’s consolidated statements of income. The Company records its interest rate swap agreements at fair value and is presented on a gross basis within other assets and other liabilities on the consolidated statements of financial condition. Changes in the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the consolidated statement of income.
