Allowance for Loan Losses (Allowance)

Prior to the Adoption of FASB ASC 326 on January 1, 2022, which introduced the CECL methodology for credit losses, the allowance for loan losses was composed of the result of two independent analyses pursuant to the provisions of ASC 450-20, Loss Contingencies and ASC 310-10-35, Receivables. The ASC 450-20 analysis was intended to quantify the inherent risks in the performing loan portfolio. The ASC 310-10-35 analysis included a loan-by-loan analysis of impaired loans, primarily consisting of loans reported as nonaccrual or troubled-debt restructurings.

The allowance allocation began with a process of estimating the probable losses in each of the twelve loan segments. The estimates for these loans were based on our historical loss data for that category over twenty quarters. Each segment was then analyzed such that an allocation of the allowance was estimated for each loan segment.

The estimated loan loss allocation for all twelve loan portfolio segments was then adjusted for several “environmental” factors. The allocation for environmental factors was particularly subjective and did not lend itself to exact mathematical calculation. This amount represented estimated probable inherent credit losses which existed, but had not yet been identified, as of the balance sheet date, and were based upon quarterly trend assessments in delinquent and nonaccrual loans, unanticipated charge-offs, credit concentration changes, prevailing economic conditions, changes in lending personnel experience, changes in lending policies, increase in interest rates, or procedures and other influencing factors. These environmental factors were considered for each of the twelve loan segments and the allowance allocation, as determined by the processes noted above for each component, was increased or decreased through provision expense based on the incremental assessment of those various environmental factors.

We then tested the resulting allowance by comparing the balance in the allowance to industry and peer information. Our management then evaluated the result of the procedures performed, including the result of our testing, and concluded on the appropriateness of the balance of the allowance in its entirety. The board of directors reviewed and approved the assessment prior to the filing of quarterly and annual financial information.

A loan was impaired when, based on current information and events, it was probable that we would be unable to collect all amounts due according to the contractual terms of the loan agreement. Collection of all amounts due according to the contractual terms means that both the interest and principal payments of a loan would be collected as scheduled in the loan agreement.

An impairment allowance was recognized if the fair value of the loan was less than the recorded investment in the loan (recorded investment in the loan was the principal balance plus any accrued interest, net of deferred loan fees or costs and unamortized premium or discount). The impairment was recognized through the allowance. Loans that were impaired were recorded at the present value of expected future cash flows discounted at the loan’s effective interest rate, or if the loan was collateral dependent, impairment measurement was based on the fair value of the collateral, less estimated disposal costs. If the measure of the impaired loan was less than the recorded investment in the loan, the Company recognized an impairment by creating a valuation allowance with a corresponding charge to the provision for loan losses or by adjusting an existing valuation allowance for the impaired loan with a corresponding charge or credit to the provision for loan losses. Management believes it followed appropriate accounting and regulatory guidance in determining impairment and accrual status of impaired loans.
