[1] Since the Fund is newly organized, "Other Expenses" and "Acquired Fund Fees and Expenses" are based on estimated expenses for the current fiscal year.
[2] Expenses related to short sales include borrowing costs and margin account maintenance costs. When the Fund sells short a security that pays interest or dividends, the Fund is obligated to pay the equivalent of the interest or dividend rate to the lender and records this as an expense of the Fund.
[3] "Acquired Fund" means any investment company in which the Fund invests or has invested during the previous fiscal period. 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.
[4] The Fund's administrator has entered into a Fund Accounting and Administration Agreement with the Fund that runs through January 31, 2014. The agreement can only be terminated prior to that date at the discretion of the Fund's Board of Trustees. The Fund's administrator receives payments under the agreement at a maximum annual rate of 0.50%. In conjunction with the Fund Accounting and Administration Agreement, the Advisor has entered into an Operating Plan with the Fund's administrator, also through January 31, 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 $40 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 2.50% 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 2.50% 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.
