Performance data includes the performance of the predecessor entity for periods before the Fund’s registration became effective. The predecessor entity was not registered under the 1940 Act, and therefore, was not subject to certain investment restrictions that are imposed by the 1940 Act. If the predecessor entity had been registered under the 1940 Act, the predecessor entity’s performance may have been lower.
