Performance Table Narrative

The following table shows the average annual total returns for each class of the fund that has been in operation for at least one full calendar year. The fund’s performance information included in the table is compared with a regulatory required index that represents an overall securities market (Bloomberg U.S. Aggregate Bond Index). In addition, the table may also include one or more indexes that align to the fund’s investment strategy.

 

In addition, the table shows hypothetical after-tax returns to demonstrate how taxes paid by a shareholder may influence returns. 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. After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k) account or an IRA. After-tax returns are shown only for the Investor Class and will differ for other share classes.

The following table shows the average annual total returns for each class of the fund that has been in operation for at least one full calendar year. The fund’s performance information included in the table is compared with a regulatory required index that represents an overall securities market (Russell 3000® Index).

In addition, the table shows hypothetical after-tax returns to demonstrate how taxes paid by a shareholder may influence returns. 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. After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k) account or an IRA. After-tax returns are shown only for the Investor Class and will differ for other share classes.

Performance Table Narrative

The following table shows the average annual total returns for each class of the fund that has been in operation for at least one full calendar year. The fund’s performance information included in the table is compared with a regulatory required index that represents an overall securities market (Russell 3000® Index). In addition, the table may also include one or more indexes that align to the fund’s investment strategy.

 

In addition, the table shows hypothetical after-tax returns to demonstrate how taxes paid by a shareholder may influence returns. 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. After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k) account or an IRA. After-tax returns are shown only for the Investor Class and will differ for other share classes.
