The purchase price and interest rate of this security is fixed at trade date, although the Fund does not earn any interest on this until settlement date. The fund has segregated assets with a current value at least equal to the amount of the forward commitment. Accordingly, the market value of $11,276,464 of Federal National Mortgage Assn., 5.500%, 9-1-35 has been segregated to cover the forward commitment.

Rule 144A securities amounted to $93,472,330 or 8.20% of the Fund's total investments as of August 31, 2005.
	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 total investments of the Fund.
	The cost of investments owned on August 31, 2005, including short-term investments, was $1,127,230,526. Gross unrealized appreciation and depreciation of investments aggregated $27,278,635 and $14,196,969, respectively, resulting in net unrealized appreciation of $13,081,666.
