| Performance Table Narrative | After-tax returns are calculated using the highest individual marginal federal income tax rates in effect on a given distribution reinvestment date and do not reflect the impact of state and local taxes. Your actual after-tax returns may differ from those shown and depend on your tax situation. The after-tax returns do not apply to shares held in an individual retirement account (“IRA”), 401(k), or other tax-advantaged account. The Return After Taxes on Distributions and Sale of Fund Shares may be greater than other returns for the same period due to a tax benefit of realizing a capital loss on the sale of Fund shares. |
