The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods and that you earn a 5% return each year. The example also assumes that the fund’s operating expenses remain the same, except that it reflects the rate and duration of any fee waivers noted in the table above. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 119 383 666 1472 99 320 559 1243 84 273 478 1068 712 1009 1328 2226 221 691 1186 2358 170 538 930 2024 99 320 559 1243 84 273 478 1068 2 6 11 26 Purchases of $1 million or more may be subject to a contingent deferred sales charge of 1.00% if the shares are redeemed within one year of the date of the purchase.

The advisor has agreed to waive the G Class’s management fee in its entirety. The advisor expects this fee waiver to remain in effect permanently and cannot terminate it without the approval of the Board of Directors.
