| Performance Table Uses Highest Federal Rate |
After-tax returns are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state and local taxes.
|
| Performance Table Not Relevant to Tax Deferred |
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) plan or an individual retirement account (“IRA”).
|
| Performance Table Explanation after Tax Higher |
Return After Taxes on Distributions and Sale of Fund Shares 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.
