The Fund may have “Total annual fund operating expenses after fee waiver” greater than the expense cap as a result of any acquired fund fees and expenses or other expenses that are excluded from the calculation. The Investment Manager is entitled to reimbursement by the Fund of fees waived during any of the previous 36 months beginning on the date of the expense limitation agreement. The agreement will expire when it reaches its termination or when the investment adviser ceases to serve as such (subject to recoupment rights) and it can be terminated by the Fund’s Board of Directors, subject to the recoupment rights of the Investment Manager.
