[3] 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 Other Expenses, as applicable, through May 30, 2015 to the extent that Total Annual Fund Operating Expenses exceed 1.55% for the A Class, 2.30% for the C Class, 1.25% for the Y Class, 1.15% for the Institutional Class and 1.53% for the Investor Class (excluding taxes, brokerage commissions, acquired fund fees and expenses and other extraordinary expenses such as litigation).
