Lipper Flexible Portfolio Funds is a class grouping of funds that allocate investments across various asset classes, including domestic common stocks, bonds, and money market instruments with a focus on total return.

[1] "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.
[2] 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, extraordinary expenses, payments under the Rule 12b-1 distribution plan, and acquired fund fees and expenses) to not more than 1.00% of the average daily net assets of the Fund through January 31, 2018 . The Expense Limitation Agreement may not be terminated prior to that date. The Advisor cannot recoup from the Fund any amounts paid by the Advisor under the Expense Limitation Agreement. Further, net annual operating expenses for the Fund may exceed those contemplated by the waiver due to acquired fund fees and other expenses that are not waived under the Expense Limitation Agreement.
[3] After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown and are not applicable to investors who hold Fund shares through tax-deferred arrangements such as an individual retirement account (IRA) or 401(k) plan.
