Other Expenses, Interest Expense, Total Annual Fund Operating Expenses and Total Annual Fund

Operating Expenses After Fee Waivers and/or Expense Reimbursements have been restated to reflect

expenses expected to be incurred in the current fiscal year.

The Adviser and certain of its affiliates on their own initiative have agreed to waive certain amounts of

their respective fees and/or reimburse expenses. Total annual fund operating expenses (excluding

acquired fund fees and expenses, interest expense, extraordinary expenses and proxy-related expenses, if

any) paid by the Fund's A, C, F and IS classes (after the voluntary waivers and/or reimbursements) will not

exceed 0.83%, 1.58%, 0.83% and 0.58% (the "Fee Limit"), respectively, up to but not including the later

of (the "Termination Date"): (a) December 1, 2026; or (b) the date of the Fund's next effective Prospectus.

While the Adviser and its affiliates currently do not anticipate terminating or increasing these

arrangements prior to the Termination Date, these arrangements may only be terminated or the Fee Limit

increased prior to the Termination Date with the approval of the Fund's Board of Directors.

**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:
