[2] The Manager has contractually agreed to reduce and/or reimburse the A Class, C Class, Y Class, Institutional Class, and Investor Class of the Fund for Distribution Fees and Other Expenses, as applicable, through December 31, 2013 to the extent that Total Annual Fund Operating Expenses exceed 1.29% for the A Class, 2.04% for the C Class, 0.89% for the Y Class, 0.79% for the Institutional Class, and 1.17% for the Investor Class (excluding taxes, brokerage commissions, acquired fund fees and expenses and other extraordinary expenses such as litigation).
