Credit Quality Indicators The Company considers credit quality indicators to monitor the credit risk in the loan portfolio including volume and severity of loan delinquencies, nonaccrual loans, internal grading of loans, historical credit loss experience and economic conditions. These indicators are reviewed and updated regularly throughout the year. An internal risk grading system is used to indicate the credit risk of loans. The loan grades used by the Company are for internal risk identification purposes and do not directly correlate to regulatory classification categories or any financial reporting definitions. The general characteristics of the risk grades and the table summarizing the Company’s gross loans held for investment by year of origination and internally assigned credit grades as of December 31, 2023, are disclosed in Note (5) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. The Company’s revolving loans that are converted to term loans are not material and therefore have not been presented.

Allowance for Credit Losses Methodology The Company determines its provision for credit losses and allowance for credit losses using the current expected credit loss methodology that is referred to as the current expected credit loss ("CECL") model. The allowance for current expected credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The allowance for credit losses methodology is disclosed in Note (5) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. The following table details activity in the allowance for credit losses on loans for the period presented. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.

Purchased Credit Deteriorated Loans The Company has previously purchased loans, for which there was, at acquisition, evidence of more than insignificant deterioration of credit quality since origination. The Company did not purchase credit-deteriorated loans during the three month period ended March 31, 2024 or March 31, 2023. Collateral Dependent Loans A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. During the three months ended March 31, 2024 and 2023, no material amount of interest income was recognized on collateral-dependent loans subsequent to their classification as collateral-dependent. The following table summarizes collateral-dependent gross loans held for investment by collateral type and the related specific allocation as follows:
