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. After-tax returns on distributions and redemptions may be higher than after-tax returns on distributions due to tax credits for realized losses a shareholder may experience upon the redemption of fund shares.
