[4] Investment is not a qualifying investment as defined under Section 55(a) of the 1940 Act. Non-qualifying assets represent 28.8% of total investments at fair value as of December 31, 2023. 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).
[5] The fair value of the investment was determined using significant unobservable inputs.

[7] All debt investments are income producing, unless otherwise noted. The Company’s external investment adviser, Barings, determines in good faith the fair value of the Company’s investments in accordance with a valuation policy and processes established by the Adviser, which have been approved by the Company’s board of directors (the “Board”), and the Investment Company Act of 1940, as amended (the “1940 Act”). In addition, all debt investments are variable rate investments unless otherwise noted. Index-based floating interest rates are generally subject to a contractual minimum interest rate. 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 Dollar Offered Rate (“CDOR”), 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 reset 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.
[8] All of the Company’s portfolio company investments (including joint venture investments), which as of December 31, 2023 represented 208.0% of the Company’s net assets, are subject to legal restrictions on sales. The acquisition date represents the date of the Company’s initial investment in the relevant portfolio company.

Variable rate loans to the Company’s portfolio companies bear interest at a rate that may be determined by reference to LIBOR, SOFR, EURIBOR, BBSY, STIBOR, CDOR, SONIA, SARON, NIBOR, BKBM or an alternate base rate (commonly based on the Federal Funds Rate or the Prime Rate), at the borrower’s option, which reset 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.
