[1] The expense information in the table has been restated to reflect current fees rather than the fees in effect during the previous fiscal year.
[2] "Acquired Fund" means any investment company in which the Fund invests or has invested during the period. Since the Fund is newly organized, "Acquired Fund Fees and Expenses" are based on estimated expenses for the current 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 will reflect the operating expenses of the Fund and do not include Acquired Fund Fees and Expenses.
[3] The Fund's administrator has entered into a Fund Accounting and Administration Agreement with the Fund that covers the regular operating expenses of the Fund for an inclusive fee of 0.25% (with the exception of management fees, distribution and/or service (12b-1) fees, acquired fund fees and expenses, and extraordinary expenses), even if such operating expenses exceed the inclusive fee. The agreement runs through October 1, 2014 and can only be terminated prior to that date at the discretion of the Fund's Board of Trustees. The Fund's administrator cannot recoup from the Fund any regular operating expenses in excess of the inclusive fee. In conjunction with the Fund Accounting and Administration Agreement, the Advisor has entered into an Operating Plan with the Fund's administrator, also through October 1, 2014 under which it has agreed to (i) to pay the administrator a fee based on the daily average net assets of the Fund when net assets are below $39 million; (ii) if these payments are less than a designated minimum, then the Advisor pays a fee that makes up the difference; and (iii) to assume expenses of the Fund outlined in the Operating Plan that are not covered by the fee paid under Fund Accounting and Administration Agreement. These measures are intended to limit the Fund's operating expenses to 1.25% of the average daily net assets, exclusive of brokerage fees and commissions, taxes, borrowing costs (such as interest or dividend expenses on securities sold short), acquired fund fees and expenses, extraordinary expenses, and distribution and/or service (12b-1) fees. The Fund's net expense ratio will be higher than 1.25% to the extent that the Fund incurs expenses excluded from this arrangement. The Operating Plan can only be terminated prior to the conclusion of the current term with the approval of the Fund's Board of Trustees.
