[1] Because there is no readily available market value for these investments, the fair value of each of these investments is determined in good faith using significant unobservable inputs by the Company’s board of directors (the “Board”) as required by the 1940 Act. See Note 4 “Fair Value Measurements” in the accompanying notes to the consolidated financial statements.
