[2] The provisions of the 1940 Act classify investments based on the level of control that we maintain in a particular portfolio company. As defined in the 1940 Act, a company is generally presumed to be “non-controlled” when we own 25% or less of the portfolio company’s voting securities and “controlled” when we own more than 25% of the portfolio company’s voting securities.
