Supplement to the Fund's Prospectus dated April 29, 2005

The following chart replaces the information for annual fund operating expenses of Class R shares in the Profile section of the Fund's Prospectus titled "What are the Fund's fees and expenses?". These changes reflect the introduction of a 12b-1 fee waiver for Class R shares effective August 1, 2005:

Annual fund operating expenses are deducted from the Fund's assets.	CLASS	R
	Management fees	0.50%
	Distribution and service (12b-1) fees1	0.60%
	Other expenses2	0.28%
	Total operating expenses	1.38%
	Fee waivers and payments1, 3	(0.23%)
	Net expenses	1.15%

This example is intended to help you compare the cost of investing in the Fund to the cost of investing in other mutual funds with similar investment objectives. We show the cumulative amount of Fund expenses on a hypothetical investment of $10,000 with an annual 5% return over the time shown.4 This is an example only, and does not represent future expenses, which may be greater or less than those shown here.	CLASS	R
	1 year	$117
	3 years	$414
	5 years	$733
	10 years	$1,637

1 Class R shares are subject to a 12b-1 fee of 0.60% of average daily net assets. The Distributor has contracted to limit the Class R shares 12b-1 fees through April 30, 2006 to no more than 0.50% of average daily net assets.

2 Other expenses have been restated to reflect an expected decrease in other expenses in the current fiscal year due to a reduction in transfer agency costs associated with servicing retirement accounts.

3 The investment manager has contracted to waive fees and pay expenses through April 30, 2006 in order to prevent total operating expenses (excluding any 12b-1 fees, taxes, interest, brokerage fees, extraordinary expenses and certain insurance costs) from exceeding 0.65% of average daily net assets.

4 The Fund's actual rate of return may be greater or less than the hypothetical 5% return we use here. This example reflects the net operating expenses with expense waivers for the one-year contractual period and the total operating expenses without waivers for years two through 10.

The following replaces the information in the fifth bullet point for Class R shares in the "About your account: Investing in the Fund" section of the Prospectus under "Choosing a share class" on page 14:
