[1] Securities are exempt from registration under Rule 144A of the Securities Act of 1933, as amended, and are restricted securities. Money market funds are valued at net asset value and are considered level 1 investments within the fair value hierarchy.
[2] Percentages are based on net assets of $392,665,468 as of February 28, 2025.
[3] Because there is no “readily available market quotations” (as defined in the 1940 Act) for these investments, the fair values of these investments were determined using significant unobservable inputs and approved in good faith by our board of directors.  These investments have been included as Level 3 in the Fair Value Hierarchy (see Note 3 to the consolidated financial statements).
