     investment opportunities for a Fund in certain markets in which limitations
     are imposed by regulators upon the amount of investment by affiliated
     investors, in the aggregate or in individual issuers. From time to time, a
     Fund's activities also may be restricted because of regulatory restrictions
     applicable to CMA and its affiliates, and/or their internal policies.
