The aggregate percentage insured by an individual financial institution ranged from 2.1% to 23.4% of total investments.

(3)

Security exempt from registration under Rule 144A of the Securities Act of 1933. These securities may be sold in transactions exempt from registration, normally to qualified institutional buyers. At December 31, 2006, the aggregate value of the securities is $2,179,141 or 5.6% of the Fund’s net assets applicable to common shares.
