[1] Acquired Fund Fees and Expenses for the Fund’s current fiscal year are the indirect costs of investing in other investment companies. The total annual fund operating expenses in this fee table will not correlate to the expense ratio in the Fund’s financial highlights, which only reflect the direct operating expenses incurred by the Fund.
[2] Magnetar Asset Management LLC (the “Adviser”) has contractually agreed to reduce its management fees, and may reimburse the Fund for its operating expenses, in order to ensure that Total Annual Fund Operating Expenses (excluding Rule 12b-1 fees, taxes, leverage/borrowing interest, interest expense, dividends paid on short sales, brokerage and other transactional expenses, acquired fund fees and expenses, expenses incurred in connection with any merger or reorganization, or extraordinary expenses) do not exceed 1.37% of the average daily net assets of each share class of the Fund (the “Expense Cap”). The Expense Cap will remain in effect through at least April 30, 2021 and may continue annually thereafter, unless sooner terminated. The Expense Cap may be terminated (i) at any time upon 60 days’ written notice by the Trust’s Board of Trustees (the “Board”) or (ii) at the end of the then-current term and upon 60 days’ written notice by the Adviser. The Adviser may request recoupment of previously waived fees and reimbursed expenses from the Fund for three years from the date they were waived or reimbursed, provided that the Fund is able to make the recoupment without exceeding the lesser of the Expense Cap (i) in effect at the time of the waiver or reimbursement, or (ii) in effect at the time of recoupment.
