The complaint accuses the defendants of violations of the Securities Act of 1933 and the Investment Company Act by virtue of the Fund's failure to comply with its investment objective to secure a high level of current interest income as is consistent with preservation of capital as stated in the Fund's Registration Statement and Prospectus. According to the complaint, because the Fund engaged in excessively risky investment strategies by concentrating its investments in large positions in low rated bonds, bonds not reviewed by an independent rating agency and by portfolio concentration in high risk securities including, Tobacco Bonds, Dirt Bonds, and derivative instruments known as "inverse floaters," the Fund suffered an approximate 33% decline in the net asset value in 2008.
