The Fund’s advisor has contractually agreed to waive its fees and/or pay for operating expenses of the Fund to ensure that total annual fund operating expenses (excluding any  taxes, leverage interest, brokerage commissions, dividend and interest expenses of short sales, acquired fund fees and expenses (as determined in accordance with Form N-1A), expenses incurred in connection with any merger or reorganization  and extraordinary expenses such as litigation expenses) do not exceed 1.35%, 2.10% and 1.10% of the  average daily net assets of the Class A Shares, Class C Shares and Institutional Class Shares, respectively.  This agreement is in effect until April 30, 2018, and may be terminated before that date only by the Trust’s Board of Trustees.  The Fund’s advisor is permitted to seek reimbursement from the Fund, subject to certain limitations, of fees waived or payments made to the Fund for a period ending three full fiscal years after the date of the waiver or payment.
