	Income Tax Information

	The following information is presented on an income tax basis. Differences between amounts for financial statement
	and federal income tax purposes are primarily due to timing differences in recognizing income on taxable market
	discount securities and timing differences in recognizing certain gains and losses on security transactions.

	At March 31, 2005, the cost of investments was $139,642,911.

	Gross unrealized appreciation and gross unrealized depreciation of investments at March 31, 2005, were as
	follows:

	Gross unrealized:
	Appreciation	$6,199,870
	Depreciation	(486,519)

	Net unrealized appreciation of investments	$5,713,351


(1)	All percentages shown in the Portfolio of Investments are based on net assets applicable to Common shares
	unless otherwise noted.
*	Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There
	may be other call provisions at varying prices at later dates.
**	Ratings: Using the higher of Standard & Poor's or Moody's rating.
***	Securities are backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency
	securities which ensures the timely payment of principal and interest. Such securities are normally considered
	to be equivalent to AAA rated securities.
N/R	Investment is not rated.
(WI)	Security purchased on a when-issued basis.
†	Security has a maturity of more than one year, but has variable rate and demand features which qualify it as
	a short-term security. The rate disclosed is that in effect at the end of the reporting period. This rate changes
	periodically based on market conditions or a specified market index.
