Gross Expense Ratio is the fund's total operating expense ratio from the fund's most recent prospectus.

Net Expense Ratio reflects the reduction of expenses from fee waivers and reimbursements. Elimination of these reductions will result in higher expenses and lower performance. These reductions will continue until at least August 31, 2016.
