The Company's ACL on off-balance sheet credit exposures is recognized as a liability within Accrued interest and other liabilities on the consolidated balance sheet, with adjustments to the ACL recognized in Credit loss expense in the consolidated statement of income. In accordance with previously applicable GAAP, there was no ACL on off-balance sheet credit exposures required during the year ended December 31, 2022. The Company's activity in the ACL on off-balance sheet credit exposures for the year ended December 31, 2023 was as follows:

Risk and collateral ratings are assigned to loans and are subject to ongoing monitoring by lending and credit personnel, with such ratings updated annually or more frequently if warranted. The following is an overview of the Company's loan rating system:
1-3 Rating - Pass
Risk-rating grades "1" through "3" comprise those loans ranging from those with lower than average credit risk, defined as borrowers with high liquidity, excellent financial condition, strong management, favorable industry trends or loans secured by highly liquid assets, through those with marginal credit risk, defined as borrowers that, while creditworthy, exhibit some characteristics requiring special attention by the account officer.
4-4.5 Rating - Satisfactory/Monitor
Borrowers exhibit potential credit weaknesses or downward trends warranting management's attention. While potentially weak, these borrowers are currently marginally acceptable; no loss of principal or interest is envisioned. When warranted, these credits may be monitored on the watch list.
5-7 Rating - Substandard
Borrowers exhibit well defined weaknesses that jeopardize the orderly liquidation of debt. The loan may be inadequately protected by the net worth and paying capacity of the obligor and/or the underlying collateral is inadequate.
The following table summarizes the Company's loans by year of origination and by loan ratings applied by management to the Company's loans by class as of December 31, 2023:

There was one revolving residential real estate loan totaling $17 thousand in process of foreclosure at December 31, 2023 and one residential real estate loan totaling $28 thousand in process of foreclosure at December 31, 2022. Aggregate interest on nonaccrual loans not recognized was $143 thousand as of December 31, 2023 and $59 thousand as of December 31, 2022.
Loans that do not share risk characteristics are evaluated on an individual basis. Loans that are individually evaluated and collateral dependent represent loans that the Company has determined foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and the Company expects repayment of the loan to be provided substantially through the sale of the collateral. For these loans, the ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the loan at the measurement date.
The following table presents collateral dependent loans to borrowers experiencing financial difficulty by loan class and collateral type as of the balance sheet dates:

Collateral dependent loans are loans for which the repayment is expected to be provided substantially by the underlying collateral and there are no other available and reliable sources of repayment.

For periods prior to the adoption of CECL, loans were evaluated for impairment and may have been classified as impaired when management believed it was probable that the Company would not collect all the contractual interest and principal payments as scheduled in the loan agreement. Under previously applicable GAAP, a specific reserve amount was allocated to the ACL for individual loans that had been classified as impaired based on management's estimate of the fair value of the collateral for collateral dependent loans, an observable market price, or the present value of anticipated future cash flows. The Company accounted for the change in present value attributable to the passage of time in the ACL. Large groups of smaller balance homogeneous loans were collectively evaluated for impairment. Accordingly, the Company did not separately identify individual consumer, real estate or small balance commercial loans for impairment evaluation, unless such loans were subject to a restructuring agreement or had been identified as impaired as part of a larger customer relationship. Based on an evaluation of the Company's historical loss experience on substandard commercial loans, management established the commercial loan threshold for individual impairment evaluation as commercial loan relationships with aggregate balances greater than $500 thousand.
The following table provides information with respect to impaired loans by class of loan as of and for year ended December 31, 2022, prior to the adoption of CECL:

Occasionally, the Company modifies loans to borrowers experiencing financial difficulty by providing interest rate reductions, term extensions, payment deferrals or principal forgiveness. When principal forgiveness is provided, the amount of forgiveness is charged off against the ACL on loans. The following tables summarize loan modifications to borrowers experiencing financial difficulty by loan class, type of modification and the financial effect of the modifications as of and for the year ended December 31, 2023:

There were no loans to borrowers experiencing financial difficulty that were modified within the previous twelve months that had subsequently defaulted during the year ended December 31, 2023. Loans are considered defaulted at 90 days past due.

At December 31, 2023, the Company was not committed to lend any additional funds to borrowers experiencing financial difficulty for which the Company modified the terms of the loans in the form of principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay, or a term extension.
