     as forward commitments--that is, the Fund has agreed on trade date to
     take delivery of and to make payment for these securities on a delayed
     basis subsequent to the date of this schedule. The purchase price and
     interest rate of these securities are fixed at trade date, although
     the Fund does not earn any interest on these until settlement date.
     The Fund has segregated assets with a current value at least equal to
     the amount of the forward commitments.

     Accordingly, the market value of $23,746,186 of Federal National

     of net assets as of September 30, 2004.

     Parenthetical disclosure of a foreign country in the security
     description represents country of a foreign issuer, however, security
     is U.S. dollar denominated.

     The percentage shown for each investment category is the total value
     of that category as a percentage of the net assets of the Fund.

     The cost of investments owned on September 30, 2004, including
     short-term investments, was $274,458,286.

     Gross unrealized appreciation and depreciation of investments
     aggregated $8,002,687 and ($2,261,327), respectively, resulting in net
     unrealized appreciation of $5,741,360.
