[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 your tax situation and may differ from those shown and are not relevant if you hold your shares through tax-advantaged arrangements, such as 403(b) plans, 401(k) plans or individual retirement accounts (IRAs). After tax returns are shown only for the Investor Class and after tax returns for the Institutional Class will vary.
[2] Returns may be higher than other returns for the same period due to a tax benefit of realizing a capital loss on the sale of Fund shares.
