OID initially represents the value of detachable equity warrants obtained in conjunction with the acquisition of debt securities and is accreted into interest income over the term of the loan as a yield enhancement. Debt investments are placed on non-accrual status when it is probable that principal, interest or fees will not be collected according to contractual terms. When a debt investment is placed on non-accrual status, the Company ceases to recognize interest and fee income until the portfolio company has paid all principal and interest due or demonstrated the ability to repay its current and future contractual obligations to the Company. The Company may not apply the non-accrual status to a loan where the investment has sufficient collateral value to collect all of the contractual amount due and is in the process of collection. Interest collected on non-accrual investments are generally applied to principal.</span></p><p style="text-indent:4.533%;font-size:10.0pt;margin-top:6.0pt;line-height:1.15;font-family:Times New Roman;margin-bottom:0.0pt;text-align:left;"><span style="background-color:rgba(0,0,0,0);color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:"Times New Roman", serif;min-width:fit-content;">Fee income, generally collected in advance, includes loan commitment and facility fees for due diligence and structuring, as well as fees for transaction services and management services rendered by the Company to portfolio companies and other third parties. Loan commitment and facility fees are amortized into income over the contractual life of the loan. Management fees are generally recognized as income when the services are rendered. Loan origination fees are capitalized and then amortized into interest income using the effective interest rate method. In certain loan arrangements, warrants or other equity interests are received from the borrower as additional origination fees.
