Portfolio Loans | Note 4: Portfolio Loans ​ Loan Categories ​ The Company’s lending can be summarized into five primary categories: commercial loans, commercial real estate loans, real estate construction loans, retail real estate loans, and retail other loans. Distributions of the loan portfolio by loan category were as follows (dollars in thousands): ​

​ Net deferred loan origination costs included in the balances above were $12.9 million as of June 30, 2022, compared to $9.0 million as of December 31, 2021. Net accretable purchase accounting adjustments included in the balances above reduced loans by $7.2 million as of June 30, 2022, and $8.8 million as of December 31, 2021. Commercial balances include loans originated under the PPP with an amortized cost of $7.6 million as of June 30, 2022, and $75.0 million as of December 31, 2021. ​ There were no retail real estate loans purchased during the three or six months ended June 30, 2022. In comparison, the Company purchased $32.2 million of retail real estate loans during the three and six months ended June 30, 2021. ​ Risk Grading ​ The Company utilizes a loan grading scale to assign a risk grade to all of its loans. A description of the general characteristics of each grade is as follows: ​
| ● | Pass – This category includes loans that are all considered acceptable credits, ranging from investment or near investment grade, to loans made to borrowers who exhibit credit fundamentals that meet or exceed industry standards.
​
| ● | Watch – This category includes loans that warrant a higher-than-average level of monitoring to ensure that weaknesses do not cause the inability of the credit to perform as expected. These loans are not necessarily a problem due to other inherent strengths of the credit, such as guarantor strength, but have above average concern and monitoring.
​
| ● | Special mention – This category is for “Other Assets Specially Mentioned” loans that have potential weaknesses, which may, if not checked or corrected, weaken the asset or inadequately protect the Company’s credit position at some future date.
​
| ● | Substandard – This category includes “Substandard” loans, determined in accordance with regulatory guidelines, for which the accrual of interest has not been stopped. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
​
| ● | Substandard non-accrual – This category includes loans that have all the characteristics of a “Substandard” loan with additional factors that make collection in full highly questionable and improbable. Such loans are placed on non-accrual status and may be dependent on collateral with a value that is difficult to determine.
​ All loans are graded at their inception. Commercial lending relationships that are $1.0 million or less are usually processed through an expedited underwriting process. Most commercial loans greater than $1.0 million are included in a portfolio review at least annually. Commercial loans greater than $0.35 million that have a grading of special mention or worse are typically reviewed on a quarterly basis. Interim reviews may take place if circumstances of the borrower warrant a more frequent review. ​ The following table is a summary of risk grades segregated by category of portfolio loans (dollars in thousands): ​

​ Gross interest income recorded on 90+ days past due loans, and that would have been recorded on non-accrual loans if they had been accruing interest in accordance with their original terms, was $0.3 million and $0.5 million for the three and six months ended June 30, 2022, respectively. Gross interest income recorded on 90+ days past due loans, and that would have been recorded on non-accrual loans if they had been accruing interest in accordance with their original terms, was $0.4 million and $0.9 million for the three and six months ended June 30, 2021, respectively. The amount of interest collected on those loans and recognized on a cash basis that was included in interest income was insignificant for the three months ended June 30, 2022, and was $0.4 million for the six months ended June 30, 2022. The amount of interest collected on those loans and recognized on a cash basis that was included in interest income was insignificant for the three and six months ended June 30, 2021. ​ Troubled Debt Restructurings ​ TDR loan balances are summarized as follows (dollars in thousands): ​

​ There were no TDRs entered into during the 12 months ended June 30, 2022, or 2021, that had subsequent defaults during the three or six months ended June 30, 2022, or 2021. A default occurs when a loan is 90 days or more past due or transferred to non-accrual. ​ Gross interest income that would have been recorded in the three and six months ended June 30, 2022, and 2021, if TDRs had performed in accordance with their original terms compared with their modified terms, was insignificant. ​ As of June 30, 2022, the Company had $0.8 million of residential real estate in the process of foreclosure. The Company follows Federal Housing Finance Agency guidelines on single-family foreclosures and real estate owned evictions on portfolio loans. ​ Loans Modified Under the CARES Act or Interagency Statement ​ The CARES Act provided financial institutions the option to temporarily suspend certain requirements under GAAP related to TDRs for a limited period of time to account for the effects of COVID-19. Federal regulatory agencies, in consultation with FASB, also issued an Interagency Statement to encourage financial institutions to work with borrowers affected by COVID-19, and to update guidance which allowed banks to modify loans of customers stressed by COVID-19 without having to classify the loan as a TDR. The Company’s TDR loan totals do not include the following modified loans with payment deferrals that fall under the CARES Act or Interagency Statement, which suspended GAAP requirements related to TDR classification (dollars in thousands): ​

​ Loans Evaluated Individually ​ The Company evaluates loans with disparate risk characteristics on an individual basis. The following tables provide details of loans evaluated individually, segregated by category. The unpaid principal balance represents customer outstanding contractual principal balances excluding any partial charge-offs. Recorded investment represents the amortized cost of customer balances net of any partial charge-offs recognized on the loan. Average recorded investment is calculated using the most recent four quarters (dollars in thousands): ​

​ Management's evaluation as to the ultimate collectability of loans includes estimates regarding future cash flows from operations and the value of property, real and personal, pledged as collateral. These estimates are affected by changing economic conditions and the economic prospects of borrowers. Collateral dependent loans are loans in which repayment is expected to be provided solely by the underlying collateral and there are no other available and reliable sources of repayment. Loans are written down to the lower of cost or fair value of underlying collateral, less estimated costs to sell. The Company had $4.1 million and $7.9 million of collateral dependent loans secured by real estate or business assets as of June 30, 2022, and December 31, 2021, respectively. ​ Allowance for Credit Losses ​ Management estimates the ACL balance using relevant available information from internal and external sources relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. The cumulative loss rate used as the basis for the estimate of credit losses is comprised of the Company’s historical loss experience beginning in 2010. As of June 30, 2022, the Company expects continued economic uncertainty in the markets in which it operates, and around levels of delinquencies, over the next 12 months. Management adjusted the historical loss experience for these expectations with an immediate reversion to historical loss rate beyond this forecast period. PPP loans were excluded from the ACL calculation as they are 100% government guaranteed. ​ The following tables summarize activity in the ACL. Allocation of a portion of the ACL to one category does not preclude its availability to absorb losses in other categories (dollars in thousands): ​
