[1] Since the Fund has not yet commenced operations, "Other Expenses" and "Acquired Fund Fees and Expenses" are based on estimated expenses for the current fiscal year.
[2] "Acquired Fund" means any investment company in which the Fund invests or has invested during the previous fiscal year. The "Total Annual Fund Operating Expenses" and "Net Annual Fund Operating Expenses" will not match the Fund's gross and net expense ratios reported in the Financial Highlights from the Fund's financial statements, which reflect the operating expenses of the Fund and do not include Acquired Fund Fees and Expenses.
[3] The Advisor has entered into an Expense Limitation Agreement with the Fund under which it has agreed to waive or reduce its fees and to assume other expenses of the Fund, if necessary, in an amount that limits the Fund's annual operating expenses (exclusive of interest, taxes, brokerage fees and commissions, borrowing costs, acquired fund fees and expenses, other expenditures which are capitalized in accordance with generally accepted accounting principles, other extraordinary expenses not incurred in the ordinary course of the Fund's business, and payments under the Rule 12b-1 distribution plan) to not more than 1.50% of the average daily net assets of the Fund through July 31, 2016. The Expense Limitation Agreement may not be terminated prior to that date. The Fund's net expense ratio will be higher than 1.50% to the extent that it incurs expenses excluded from the Expense Limitation Agreement. The Advisor cannot recoup from the Fund any amounts paid by the Advisor under the Expense Limitation Agreement.
