Performance information for Class A and Class C shares prior to April 22, 2016 and for Class Z shares prior to November 20, 2019 (Class Z inception date) reflects the performance of the Fund’s Advisor Class shares adjusted to reflect the expense differences between these Classes of shares.
[2] After-tax returns: – Are shown for Advisor Class shares only and will vary for the other Classes of shares because these Classes have different expense ratios; – Are an estimate, which is based on 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 individual investor’s tax situation and are likely to differ from those shown; and – Are not relevant to investors who hold fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.
