About Expense Ratios: All mutual funds have expense ratios which represent what shareholders pay for operating expenses and management fees. Expense ratios are expressed as an annualized percentage of a fund's average net assets paid out in expenses. Net expense ratios reflect adjustments due to voluntary or contractual fee waivers or expense reimbursements. Expense ratio information is as of the Fund's current prospectus, as revised and supplemented to date.
