[1] This portfolio company is not a qualifying asset under Section 55(a) of the Investment Company Act of 1940, as amended (together with the rules and regulations promulgated thereunder, the “1940 Act”). Under the 1940 Act, the Fund may not acquire any non-qualifying asset unless, at the time such acquisition is made, qualifying assets represent at least 70% of the Fund's total assets. Pursuant to Section 55(a) of the 1940 Act, 0.54% of the Fund's total assets are represented by investments at fair value and other assets that are considered “non-qualifying assets” as of December 31, 2025.
[2] Securities exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”) and may be deemed “restricted securities” subject to legal restrictions on sales. As of December 31, 2025, the aggregate fair value of these securities is $2,522.5 million, or 120.43% of the Fund’s (as defined below) total assets, may be subject to legal restrictions on sales.
[3] These assets are pledged as collateral under the Fund’s or the Fund’s consolidated subsidiaries’ various credit facilities and, as a result, are not directly available to the creditors of the Fund to satisfy any obligations of the Fund other than the obligations under each of the respective credit facilities (see “Note 5. Debt to the consolidated financial statements for more information).
[4] These investments were valued using significant unobservable inputs and are considered Level 3 investments. See “Note 8. Fair Value of Financial Instruments” to the consolidated financial statements for more information regarding the fair value of the Fund’s investment.
[5] As of December 31, 2025, the Fund had commitments to fund various delayed draw term loans and equity investments. Such commitments are subject to the satisfaction of certain conditions set forth in the documents governing these loans and there can be no assurance that such conditions will be satisfied. See “Note 7. Commitments and Contingencies” to the consolidated financial statements for more information on delayed draw term loan commitments related to certain portfolio companies.
[6] The fair value of the Fund’s investment is determined using unobservable inputs that are significant to the overall fair value measurement. See “Note 8. Fair Value of Financial Instruments” to the consolidated financial statements for more information regarding the fair value of the Fund’s investment.
