[1] Based on estimated amounts for the current fiscal year. Acquired Fund Fees and Expenses are the indirect costs of investing in other investment companies. The operating expenses in this fee table will not correlate to the expense ratio in the Fund’s financial highlights because the financial statements include only the direct operating expenses incurred by the Fund.
[2] The Fund’s adviser, Main Management Fund Advisors, LLC (the “Adviser”), has contractually agreed to reduce its fees and/or absorb expenses of the Fund, until at least February 28, 2027, to insure that total annual fund operating expenses after fee waiver and/or reimbursement (exclusive of (i) any front-end or contingent deferred loads; (ii) brokerage fees and commissions; (iii) fees and expenses associated with investments in other collective investment vehicles not registered under the Investment Company Act of 1940, as amended, (the “1940 Act”) or derivative instruments (including for example option and swap fees and expenses); (iv) borrowing costs (such as interest and dividend expense on securities sold short); (v) taxes; and (vi) extraordinary expenses, such as litigation expenses (which may include indemnification of Fund officers and Trustees, contractual indemnification of Fund service providers (other than the Adviser))) will not exceed 0.95% of the Fund’s average daily net assets. These fee waivers and expense reimbursements are subject to possible recoupment from the Fund in future years (within the three years from the time the fees were waived or reimbursed), if, after such recoupment is taken into account, the expense ratio does not exceed the lesser of the expense limits in place at the time of the waiver or those in place at the time of recapture. Further, the Adviser agrees to pay that portion of the Fund’s acquired fund fees and expenses necessary to limit the Fund’s current operating expenses plus acquired fund fees and expenses to no more than 0.99% of the Fund’s average daily net assets. This agreement may be terminated by the Board of Trustees only on 60 days’ written notice to the Adviser.
