Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 for the time periods indicated and then redeem all of your Shares at the end of those periods. Expenses assuming no redemption are also shown. The Example also assumes that your investment has a 5% return each year and that operating expenses remain the same. The Example does not reflect sales charges (loads) on reinvested dividends. If these sales charges (loads) were included, your costs would be higher. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be: 

Share Class	1 Year	3 Years	5 Years	10 Years
A:
Expenses assuming redemption	$563	$802	$1,060	$1,796
Expenses assuming no redemption	$563	$802	$1,060	$1,796
C:
Expenses assuming redemption	$294	$600	$1,032	$2,038
Expenses assuming no redemption	$194	$600	$1,032	$2,038
F:
Expenses assuming redemption	$317	$565	$732	$1,495
Expenses assuming no redemption	$217	$465	$732	$1,495
