                        NOTES TO STATEMENT OF INVESTMENTS

1. Security Valuation - Securities are valued at the last sale price or, if
unavailable, at the closing bid price. Corporate discount notes are valued at
amortized cost, which approximates value. Securities for which no ready market
exists are valued at estimated fair value by the Board of Directors.

As of March 31, 2006, the tax cost of investments was $279,136,112. Net
unrealized appreciation was $314,544,362 consisting of gross unrealized
appreciation and gross unrealized depreciation of $319,716,341 and $5,171,979,
respectively.

2. Restricted Securities - The Corporation from time to time invests in
securities the resale of which is restricted. On March 31, 2006, such
investments had an aggregate value of $109,144,885, which was equal to 18.3% of
the Corporation's net assets. Investments in restricted securities at March 31,
2006, including the acquisition dates and cost, were:
