[1] After-tax returns are calculated using the highest historical 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 the after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period.After-tax returns are for Institutional Class shares only. After-tax returns for other classes will vary.

[2] The Lipper Average’s since inception return is determined from the nearest month-end following the Fund’s inception date and not from the actual inception date of the Fund.
