through April 30, 2014, to the extent that Total Annual Fund Operating Expenses for the Fund exceed 1.34%, 2.09%, 0.94%, 0.84% and 1.22% for the A Class, C Class, Y Class, Institutional Class and Investor Class, respectively (excluding taxes, brokerage commissions, acquired fund fees and expenses and other extraordinary expenses such as litigation). The contractual expense arrangement can be changed by approval of a majority of the Fund's Board of Trustees. The Manager can be reimbursed by the Fund for any contractual or voluntary fee reductions or expense reimbursements if reimbursement to the Manager (a) occurs within three years after the Manager's own reduction or reimbursement and (b) does not cause the Total Annual Fund Operating Expenses of a class to exceed the percentage limit contractually agreed. After-tax returns are shown only for Investor Class shares; after-tax returns for other share classes will vary. 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. If you hold your Fund shares through a tax-deferred arrangement, such as an individual retirement account or a 401(k), the after-tax returns do not apply to your situation. The Total Annual Fund Operating Expenses do not correlate to the ratio of expenses to average net assets provided in the Fund's Financial Highlights table, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

In each case, the newer share classes would have had similar annual returns to the predecessor Fund&#8217;s Investor Shares, A Shares and Institutional Shares because the shares of each class represent investments in the same portfolio securities. However, because the Investor Shares had lower expenses than the Fund&#8217;s A Class and C Class now have, its performance was better than the A Class and C Class would have realized had the A Class and C Class shares been in existence since December 31, 2002. Since the Investor Shares had higher expenses than the Fund&#8217;s Institutional Class and Y Class now have, its performance was lower than the Institutional Class and Y Class would have realized in the same period.
