The Company records interest income on an accrual basis, recognizing income as earned in accordance with the contractual terms of the loan agreement, to the extent that such amounts are expected to be collected. The Company’s Structured Debt investments may generate OID. The OID received upfront typically represents the value of detachable equity, warrants, or another asset obtained in conjunction with the acquisition of debt</span><span style="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;"> </span></p><p style="text-indent:0.0%;font-size:10.0pt;margin-top:6.0pt;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;">securities. The OID is accreted into interest income over the term of the loan as a yield enhancement following the effective interest method. Additionally, certain debt investments in the Company’s portfolio earn PIK interest. The Company records PIK interest in accordance with the contractual terms of the loan agreement, to the extent that such amounts are expected to be collected. Contractual PIK interest represents contractually deferred interest that is added to the loan balance as principal and is generally due at the end of the loan term.</span><span style="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;"> </span></p><p style="text-indent:4.533%;font-size:10.0pt;margin-top:6.0pt;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;">The Company’s loan origination activities generate fee income, which is generally collected in advance and includes loan commitment, 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 capitalized and then amortized into income over the contractual life of the loan using the effective interest method. One-off fees for transaction and management services are generally recognized as income in the period when the services are rendered. The Company may also earn loan exit fees, which are contractual fees that are generally received upon the earlier of maturity or prepayment. The Company accretes loan exit fees into interest income following the effective interest method, recognizing income as earned in accordance with the contractual terms of the loan agreement, to the extent that such amounts are expected to be collected.</span><span style="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;"> </span></p><p style="text-indent:4.533%;font-size:10.0pt;margin-top:6.0pt;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;">From time to time, additional fees may be earned by the Company relating to specific loan modifications, prepayments, or other one-off events. These non-recurring fees are either amortized into fee income over the remaining term of the loan commencing in the quarter for loan modifications, or recognized currently as one-time fee income for items such as prepayment penalties, fees related to select covenant default waiver fees, and acceleration of previously deferred loan fees and OID related to early loan pay-off or material modification of the specific debt outstanding.</span><span style="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;"> </span></p><p style="text-indent:4.533%;font-size:10.0pt;margin-top:6.0pt;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;">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 determine to continue to accrue interest on 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>
