Security Ownership of Certain Beneficial Owners and Management
As of the Record Date, to our knowledge, no person would be presumed under the Investment Company Act of 1940, as amended (the “1940 Act”), to “control” us, as such term is defined in the 1940 Act.
Our Directors consist of independent Directors (Directors who are not “interested persons” (as defined in the 1940 Act) of the Company, and therefore not affiliates of AIM) (“Independent Directors”) and interested Directors. Interested Directors are “interested persons” of the Company, as defined in the 1940 Act.
The following table sets forth, as of March 31, 2020, certain ownership information with respect to our common stock for those persons whom we believe, based on public filings and/or information provided by such persons, directly or indirectly owned, controlled or held, with the power to vote, 5% or more of our outstanding common stock as of that date as well as our affiliates that directly or indirectly owned, controlled or held, with the power to vote, our outstanding common stock as of that date. Unless otherwise indicated, we believe that each beneficial owner set forth in the table has sole voting and investment power over the securities owned by it.
