In addition, all debt investments are variable rate investments unless otherwise

Variable rate loans to the Company’s portfolio companies bear interest at a rate that may be determined by reference to the Secured Overnight Financing Rate (“SOFR”), the Euro Interbank Offered Rate (“EURIBOR”), the Bank Bill Swap Bid Rate (“BBSY”), the Stockholm Interbank Offered Rate (“STIBOR”), the Canadian Overnight Repo Rate Average (“CORRA”), the Sterling Overnight Index Average (“SONIA”), the Swiss Average Rate Overnight (“SARON”), the Norwegian Interbank Offered Rate (“NIBOR”), the Bank Bill Market rate (“BKBM”) or an alternate base rate (commonly based on the Federal Funds Rate or the Prime Rate), at the borrower’s option, which resets annually, semi-annually, quarterly or monthly. For each such loan, the Company has provided the interest rate in effect on the date presented. SOFR-based contracts may include a credit spread adjustment that is charged in addition to the base rate and the stated spread. The borrower may also elect to have multiple interest reset periods for each loan.

The acquisition date represents the date of the Company’s initial investment in the relevant portfolio company.

Qualifying assets must represent at least 70% of total assets at the time of acquisition of any additional non-qualifying assets. If at any time qualifying assets do not represent at least 70% of the Company’s total assets, the Company will be precluded from acquiring any additional non-qualifying asset until such time as it complies with the requirements of Section 55(a).
[12] Some or all of the investment is or will be encumbered as security for the Company’s senior secured credit facility with Sumitomo Mitsui Banking Corporation initially entered into in March 2023 (as amended, restated, and otherwise modified from time to time, the “SMBC Credit Facility”).
