The Company adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, effective January 1, 2021. The guidance replaces the incurred loss methodology with an expected loss methodology that is referred to as the CECL methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables. It also applies to off-balance sheet credit exposures not accounted for as insurance, including loan commitments, standby letters of credits, financial guarantees, and other similar instruments. The Company adopted ASC 326 using the modified retrospective method for loans and off-balance sheet credit exposures. The Company recorded a one-time cumulative-effect adjustment to the allowance for credit losses of $11.6 million. This adjustment brought the balance of the allowance for credit losses to $67.3 million as of January 1, 2021. In addition, the Company recorded an $8.7 million liability for unfunded commitments as of January 1, 2021. The after-tax effect decreased retained earnings by $14.2 million. The adjustment was based upon the Company’s analysis of then-current conditions, assumptions and economic forecasts at January 1, 2021.

The Company adopted ASC 326 using the prospective transition approach for financial assets purchased with credit deterioration (PCD) that were previously classified as purchased credit impaired (PCI) and accounted for under ASC 310-30. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2021, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $1.9 million to allowance for credit losses.

The allowance for credit losses is measured using an average historical loss model which incorporates relevant information about past events (including historical credit loss experience on loans with similar risk characteristics), current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the loans. The allowance for credit losses is measured on a collective (pool) basis. Loans are aggregated into pools based on similar risk characteristics including borrower type, collateral and repayment types and expected credit loss patterns. Loans that do not share similar risk characteristics, primarily classified and/or TDR loans with a balance greater than or equal to $100,000, are evaluated on an individual basis.

For loans evaluated for credit losses on a collective basis, average historical loss rates are calculated for each pool using the Company’s historical net charge-offs (combined charge-offs and recoveries by observable historical reporting period) and outstanding loan balances during a lookback period. Lookback periods can be different based on the individual pool and represent management’s credit expectations for the pool of loans over the remaining contractual life. In certain loan pools, if the Company’s own historical loss rate is not reflective of the loss expectations, the historical loss rate is augmented by industry and peer data. The calculated average net charge-off rate is then adjusted for current conditions and reasonable and supportable forecasts. These adjustments increase or decrease the average historical loss rate to reflect expectations of future losses given economic forecasts of key macroeconomic variables including, but not limited to, unemployment rate, GDP, disposable income and market volatility. The adjustments are based on results from various regression models projecting the impact of the macroeconomic variables to loss rates. The forecast is used for a reasonable and supportable period before reverting to historical averages using a straight-line method. The forecast-adjusted loss rate is applied to the amortized cost of loans over the remaining contractual lives, adjusted for expected prepayments. The contractual term excludes expected extensions, renewals and modifications unless there is a reasonable expectation that a troubled debt restructuring (“TDR”) will be executed. Additionally, the allowance for credit losses considers other qualitative factors not included in historical loss rates or macroeconomic forecasts such as changes in portfolio composition, underwriting practices, or significant unique events or conditions.

ASU 2016-13 requires an allowance for off balance sheet credit exposures; unfunded lines of credit, undisbursed portions of loans, written residential and commercial commitments, and letters of credit. To determine the amount needed for allowance purposes, a utilization rate is determined either by the model or internally for each pool. Our loss model calculates the reserve on unfunded commitments based upon the utilization rate multiplied by the average loss rate factors in each pool with unfunded and committed balances. The liability for unfunded lending commitments utilizes the same model as the allowance for credit losses on loans; however, the liability for unfunded lending commitments incorporates assumptions for the portion of unfunded commitments that are expected to be funded.

Loans are placed on nonaccrual status at 90 days past due and interest is considered a loss unless the loan is well secured and in the process of collection. Payments received on nonaccrual loans are applied to principal until the loans are returned to accrual status. Loans are returned to accrual status when all payments contractually due are brought current, payment performance is sustained for a period of time, generally six months, and future payments are reasonably assured. With the exception of consumer loans, charge-offs on loans are recorded when available information indicates a loan is not fully collectible and the loss is reasonably quantifiable. Consumer loans are charged-off at specified delinquency dates consistent with regulatory guidelines.

No interest income was recorded on these loans for the three months ended March 31, 2022 and 2021, respectively.

Nonaccrual loans for which there is no related allowance for credit losses as of March 31, 2022 had an amortized cost of $3.3 million. These loans are individually assessed and do not require an allowance due to being adequately collateralized under the collateral-dependent valuation method. A collateral-dependent loan is a financial asset for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the Company’s assessment as of the reporting date. Collateral-dependent loans are identified by either a classified risk rating or TDR status and a loan balance equal to or greater than $100,000, including, but not limited to, any loan in process of foreclosure or repossession.

The following tables present the activity in the allowance for credit losses by portfolio segment for the three months ended March 31, 2022 and 2021. During the three months ended March 31, 2022, the Company did not record a provision expense on its portfolio of outstanding loans, compared to a $300,000 provision expense recorded for the quarter ended March 31, 2021.

The following table presents the activity in the allowance for unfunded commitments by portfolio segment for the three months ended March 31, 2022 and 2021. The provision for losses on unfunded commitments for the three months ended March 31, 2022 was a credit (negative expense) to provision expense of $193,000, compared to a credit (negative expense) of $673,000 for the three months ended March 31, 2021. The level and mix of unfunded commitments resulted in a decrease in the required reserve for such potential losses in each of the three month periods presented.

The portfolio segments used in the preceding tables correspond to the loan classes used in all other tables in Note 6 as follows:

At March 31, 2022, of the $3.7 million in TDRs, $2.8 million were classified as substandard using the Company’s internal grading system, which is described below. The Company had one TDR that was modified in the previous 12 months and subsequently defaulted during the three months ended March 31, 2022.

At December 31, 2021, of the $3.9 million in TDRs, $2.9 million were classified as substandard using the Company’s internal grading system. The Company had no TDRs that were modified in the previous 12 months and subsequently defaulted during the year ended December 31, 2021.

During the three months ended March 31, 2022, $221,000 of loans met the criteria for placement back on accrual status. The criteria are generally a minimum of six months of consistent and timely payment performance under original or modified terms. During the three months ended March 31, 2021, four loans designated as TDRs, totaling $27,000, met the criteria for placement back on accrual status.

The Company utilizes an internal risk rating system comprised of a series of grades to categorize loans according to perceived risk associated with the expectation of debt repayment. The analysis of the borrower’s ability to repay considers specific information,

including but not limited to current financial information, historical payment experience, industry information, collateral levels and collateral types. A risk rating is assigned at loan origination and then monitored throughout the contractual term for possible risk rating changes.

Satisfactory loans range from Excellent to Moderate Risk, but generally are loans supported by strong recent financial statements. Character and capacity of borrower are strong, including reasonable project performance, good industry experience, liquidity and/or net worth. Probability of financial deterioration seems unlikely. Repayment is expected from approved sources over a reasonable period of time.

Watch loans are identified when the borrower has capacity to perform according to terms; however, elements of uncertainty exist. Margins of debt service coverage may be narrow, historical patterns of financial performance may be erratic, collateral margins may be diminished and the borrower may be a new and/or thinly capitalized company. Some management weakness may also exist, the borrower may have somewhat limited access to other financial institutions, and that ability may diminish in difficult economic times.

Special Mention loans have weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of repayment prospects or the Bank’s credit position at some future date. It is a transitional grade that is closely monitored for improvement or deterioration.

The Substandard rating is applied to loans where the borrower exhibits well-defined weaknesses that jeopardize its continued performance and are of a severity that the distinct possibility of default exists. Loans are placed on “non-accrual” when management does not expect to collect payments consistent with acceptable and agreed upon terms of repayment.

Doubtful loans have all the weaknesses inherent to those classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable. Loans considered loss are uncollectable and no longer included as an asset.

All loans are analyzed for risk rating updates regularly. For larger loans, rating assessments may be more frequent if relevant information is obtained earlier through debt covenant monitoring or overall relationship management. Smaller loans are monitored as identified by the loan officer based on the risk profile of the individual borrower or if the loan becomes past due related to credit issues. Loans rated Watch, Special Mention, Substandard or Doubtful are subject to quarterly review and monitoring processes. In addition to the regular monitoring performed by the lending personnel and credit committees, loans are subject to review by the credit review department, which verifies the appropriateness of the risk ratings for the loans chosen as part of its risk-based review plan.

The following tables present a summary of loans by risk category and past due status separated by origination and loan class as of March 31, 2022. The remaining accretable discount of $204,000 has not been included in this table. See Note 7 for further discussion of the FDIC-assisted acquired loans and related discount.
