Investing in MLPs involves additional risks compared to the risks of common stock, including risks related to cash flow, dilution and voting rights. The Fund is classified as a “non-diversified” fund and may invest a greater portion of its assets in the securities of a single issuer. The Fund accrues income taxes for future tax liabilities associated with the portion of MLP distributions considered to be a tax-deferred return of capital and for any net operating gains as well as capital appreciation of its investments. This deferred tax liability is reflected in the daily NAV and, as a result of the Fund’s after-tax performance, could differ significantly from the underlying assets even if the pre-tax performance is closely tracked. Distributions from MLP funds have been classified as a “return of capital” which reduces the investor’s cost adjusted basis.
