Individual Investors: Separately Managed Accounts

Morningstar Proprietary Ratings reflect risk-adjusted performance as of 1/31/16. The Overall Morningstar Rating for a fund is derived from a weighted average of the performance figures associated with its three-, five- and ten-year (if applicable) Morningstar Rating metrics. For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating™ (based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance, including the effects of sales charges, loads, and redemption fees, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. The Fund's I Shares received 4 stars, A Shares with Load Waived received 4 stars, A Shares received 3 stars, and C Shares received 4 stars, each for the three-year time period ended 1/31/16 among 52 Energy Limited Partnership Funds. The load-waived rating should only be considered by investors who are not subject to a sales load. Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in distribution percentage. Morningstar ratings represented as unshaded stars are based on extended performance. These extended performance ratings are based on the historical adjusted returns prior to the inception date of the Class C shares (Class C inception was 3/31/14) and reflect the historical performance of the oldest share class (inception date for Class I and A was 2/17/11), adjusted to reflect the fees and expenses of the Class C shares. The Overall Morningstar Rating applies to the share classes noted herein and does not apply to other share classes of the Fund. Past performance is no guarantee of future performance.

Nothing on this website should be considered a solicitation to buy or an offer to sell shares of the Fund in any jurisdiction where the offer or solicitation would be unlawful under the securities laws of such jurisdiction.

Diversification does not assure a profit or protect against a loss in a declining market.

Mutual fund investing involves risk. Principal loss is possible. The Fund is nondiversified, meaning it may concentrate its assets in fewer individual holdings than a diversified fund. Therefore, the Fund is more exposed to individual stock volatility than a diversified fund. The Fund will invest in Master Limited Partnerships (MLPs) which concentrate investments in the natural resource sector and are subject to the risks of energy prices and demand and the volatility of commodity investments. Damage to facilities and infrastructure of MLPs may significantly affect the value of an investment and may incur environmental costs and liabilities due to the nature of their business. MLPs are subject to significant regulation and may be adversely affected by changes in the regulatory environment. Investments in smaller companies involve additional risks, such as limited liquidity and greater volatility. Investments in foreign securities involve greater volatility and political, economic and currency risks and differences in accounting methods. MLPs are subject to certain risks inherent in the structure of MLPs, including complex tax structure risks, limited ability for election or removal of management, limited voting rights, potential dependence on parent companies or sponsors for revenues to satisfy obligations, and potential conflicts of interest between partners, members and affiliates.

An investment in the Fund does not receive the same tax advantages as a direct investment in the MLP. The Fund is treated as a regular corporation or “C” corporation and is therefore subject to U.S. federal income tax on its taxable income at rates applicable to corporations (currently at a maximum rate of 35%) as well as state and local income taxes. MLP Funds accrue deferred 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 the MLP Fund’s after-tax performance could differ significantly from the underlying assets even if the pre-tax performance is closely tracked. The potential tax benefits from investing in MLPs depend on them being treated as partnerships for federal income tax purposes.

Return of Capital: A return, by the Fund, of an investor's monies that is not considered income and therefore is not taxed because its amount does not exceed the original investment.
