The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form

10-Q

and, therefore, do not include all footnotes as would be necessary for a fair presentation of financial position, results of operations and comprehensive income, changes in shareholders’ equity and cash flows in conformity with accounting principles generally accepted in the United States of America (“GAAP”). However, these interim unaudited consolidated financial statements reflect all adjustments (consisting solely of normal recurring adjustments and accruals) which, in the opinion of management, are necessary for a fair presentation of financial position, results of operations and comprehensive income, changes in shareholders’ equity and cash flows for the interim periods presented. These unaudited consolidated financial statements have been prepared on a basis consistent with, and should be read in conjunction with, the audited consolidated financial statements as of and for the year ended December 31, 2022, and the notes thereto, included in the Company’s Annual Report on Form

10-K

for the year ended December 31, 2022 filed with the Securities and Exchange Commission (the “SEC”), under the Securities and Exchange Act of 1934, as amended (the “Exchange Act”). The unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated.

The preparation of financial statements in conformity with GAAP 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 consolidated financial statements, and the reported amounts of revenues and expenses during the reporting periods presented. Actual results may differ from those estimates used in the Consolidated Financial Statements and related notes. Material estimates that are particularly susceptible to significant changes in the near term include estimates relating to: the determination of the allowance for credit losses; certain assets and liabilities carried at fair value; and accounting for income taxes.

Basic earnings per common share represents the amount of earnings for the period available to each share of common stock outstanding during the reporting period. Basic EPS is computed based upon net income divided by the weighted average number of common shares outstanding during the period. In determining the weighted average number of shares outstanding, vested restricted stock units are included. Diluted EPS represents the amount of earnings for the period available to each share of common stock outstanding including common stock that would have been outstanding assuming the issuance of common shares for all dilutive potential common shares outstanding during each reporting period. Diluted EPS is computed based upon net income divided by the weighted average number of common shares outstanding during each period, adjusted for the effect of dilutive potential common shares, such as restricted stock awards and units, calculated using the treasury stock method.

Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASC 326)

. This standard replaced the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. CECL requires an estimate of credit losses for the remaining estimated life of the financial asset using historical experience, current conditions, and reasonable and supportable forecasts and generally applies to financial assets measured at amortized cost, including loan receivables and

held-to-maturity

debt securities, and some

off-balance

sheet credit exposures such as unfunded commitments to extend credit. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses (“ACL”).

The Company adopted ASC 326, and all related subsequent amendments thereto, using the modified retrospective approach for all financial assets measured at amortized cost and

off-balance

sheet credit exposures. The transition adjustment of the adoption of CECL included a decrease in the allowance for credit losses on loans of $1.8 million, which is presented as a reduction to net loans outstanding, and an increase in the allowance for credit losses on unfunded loan commitments of $1.4 million, which is recorded within other liabilities. Additionally, the Company recorded an allowance for credit losses for held to maturity securities of $110,000, which is presented as a reduction to held to maturity securities outstanding. The Company recorded a net increase to retained earnings of $334,000 as of January 1, 2023 for the cumulative effect of adopting CECL, which reflects the transition adjustments noted above. Results for reporting periods beginning after January 1, 2023 are presented under CECL while prior period amounts continue to be reported in accordance with previously applicable accounting standards (“Incurred Loss”).

The ACL on loans represents the Company’s estimate of expected lifetime credit losses for its loans at the time of origination or acquisition and is maintained at a level deemed appropriate by management to provide for expected lifetime credit losses in the portfolio as of the date of the consolidated statements of financial condition. The ACL on loans is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected. Amortized cost does not include accrued interest, which management elected to exclude for the estimate of expected credit losses. The ACL on loans is increased by the provision for credit losses on loans, which is charged against current period operating results, and decreased by reversals of credit loss provisions as well as loan charge-offs, net of recoveries.

Management’s determination of the ACL on loans is based on an evaluation of the composition of the loan portfolio, current economic conditions, historical loan loss experience, reasonable and supportable forecasts, and other risk factors. Loans with similar risk characteristics are collectively assessed within pools (or segments).

The discounted cash flow (“DCF”) method is the primary credit loss estimation methodology used by the Company and involves estimating future cash flows for each individual loan and discounting them back to their present value using the loan’s contractual interest rate, which is adjusted for any net deferred fees, costs, premiums, or discounts existing at the loan’s origination or acquisition date (also referred to as the effective interest rate). The DCF method also considers factors such as loan term, prepayment or curtailment assumptions, and other relevant economic factors that could affect future cash flows. By discounting the cash flows, the method incorporates the time value of money and reflects the credit risk inherent in the loan.

The Company utilizes a forecast period of one year and then reverts to the mean of historical loss rates on a straight-line basis over the following

one-year

period. The Company considers economic forecasts of national gross domestic product, unemployment rates from the Federal Open Market Committee, and the House Price Index to inform the model for loss estimation. Historical loss rates used in the quantitative model were derived using both the Bank’s and peer bank data obtained from publicly-available sources.

Additionally, management considers qualitative and environmental factors that are likely to cause estimated credit losses within the Company’s existing portfolio to differ from historical loss (or peer) experience. Qualitative and environmental factors may include: consideration in trends of delinquencies, nonaccrual loans, and

charged-off

loans; trends in underlying collateral; effects in changes of lending policy and underwriting; regional and local economic trends; and conditions and concentrations of credit.

The Company maintains an ACL on unfunded loan commitments and other

off-balance

sheet credit exposures, if applicable, as part of other liabilities and accrued expenses in the consolidated statements of financial condition. Adjustments to the ACL on

off-balance

sheet credit exposures are made through a charge to provision for credit losses in the Company’s consolidated statements of income. The ACL on unfunded loan commitments is estimated by loan segment at each balance sheet date under the current expected credit loss model using the same methodologies as portfolio loans, taking into consideration the likelihood that funding will occur as well as any third-party guarantees.

For available for sale securities in an unrealized loss position, the Company initially assesses whether it intends to sell, or it is more likely than not that it will be required to sell, the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost is written down to fair value through income. For available for sale securities that do not meet this criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. If a credit loss exists an allowance for credit losses is recorded, through a charge to the provision to credit losses, to the extent that the fair value is less than the amortized cost basis. Accrued interest receivable on available for sale securities is excluded from the estimate of credit losses. The Company did not have any available for sale securities that required an ACL at June 30, 2023.

The Company measures expected credit losses on held to maturity investment securities on a collective basis by major security type. Accrued interest receivable on held to maturity investment securities is excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Changes in the ACL for held to maturity securities are recorded through the provision for credit losses in the consolidated statements of income.
