MLPs are limited partnerships and limited liability companies that are publicly traded and are treated as partnerships for federal income tax purposes. The units for these entities are listed and traded on a U.S. securities exchange. The Fund invests in equity securities, such as common units and common shares, in Midstream Investments. Midstream companies own and operate the logistical assets used in the energy sector and are engaged in (a) the treating, gathering, compression, processing, transmission and storage of natural gas and the transportation, fractionation and storage of natural gas liquids (primarily propane, ethane, butane and natural gasoline); (b) the gathering, transportation (including marine) and storage of crude oil; and (c) the transportation and storage of refined products (primarily gasoline, diesel fuel and jet fuel) and other hydrocarbon by-products. Midstream companies may also operate ancillary businesses, including the marketing of commodities and logistical services. The Fund will invest 75% or more of its assets in Midstream Investments that are engaged in the Midstream Energy Infrastructure. Midstream Energy Infrastructure refers to energy infrastructure companies engaged in midstream activities involving energy commodities, including gathering and processing, liquefaction, pipeline transportation, rail terminaling, and storage. The Fund also may invest up to 20% of its net assets in non-Midstream Investments, including MLPs that operate (i) other assets that are used in the energy sector, including assets used in exploring developing, producing, generating, transporting, transmitting, storing, gathering, processing, refining, distributing, mining or marketing of natural gas, natural gas liquids, crude oil, refined products, coal or electricity, or (ii) that provide energy related services. The Fund may directly invest up to but not more than 25% (or such higher amount as permitted by any applicable tax diversification rules) of total assets, at the time of investment, in equity securities of MLPs. This limit does not apply to securities issued by MLP affiliates, which are not treated as publicly traded partnerships for federal income tax purposes. The Fund is non-diversified, which means that it may invest in a limited number of issuers. The Fund may invest up to but not more than 15% of total assets in any single issuer. The Fund will invest primarily in companies located in North America, but the Fund may invest in companies located anywhere in the world. The Fund will engage in covered call writing. The Fund currently expects to write call options for the purpose of generating realized gains and distributable cash flow to investors. The Fund will only write call options on securities that the Fund holds in its portfolio (i.e., covered calls). Each long security will likely have a corresponding call option written on it. A call option on a security is a contract that gives the holder of such call option the right to buy the security underlying the call option from the writer of such call option at a specified price at any time during the term of the option. At the time the call option is sold, the writer of a call option receives a premium (or call premium) from the buyer of such call option. If the Fund writes a call option on a security, the Fund has the obligation upon exercise of such call option to deliver the underlying security upon payment of the exercise price. When the Fund writes a call option, an amount equal to the premium received by the Fund will be recorded as a liability and will be subsequently adjusted to the current fair value of the option written. Premiums received from writing options that expire unexercised are treated by the Fund as realized gains from investments on the expiration date. If the Fund repurchases a written call option prior to its exercise, the difference between the premium received and the amount paid to repurchase the option is treated as a realized gain or realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Fund has realized a gain or loss. The Fund, as the writer of the option, bears the market risk of an unfavorable change in the price of the security underlying the written option. In other words, the Fund can lose money if: (1) the Funds equity positions go down in value or (2) the price of an underlying equity exceeds the call option strike price at expiration or an open option position is closed for more than the premium the Fund received at the initial sale. Under normal market conditions, the Fund expects that it will sell call options in an amount that is 80% or more of the value of the equity investments in the Funds portfolio. The term Enhanced in the Funds name refers to the income generated from the Funds investment in Midstream Investments coupled with the income generated from the Funds covered call strategy. The Fund may also utilize standardized exchange-traded and FLexible EXchange (FLEX) options issued and guaranteed for settlement by the Options Clearing Corporation (OCC). FLEX Options are customized options contracts that trade on an exchange but provide investors with the ability to customize key contract terms like strike price, style and expiration date while achieving price discovery in competitive, transparent auctions markets and avoiding the counterparty exposure of over-the-counter (OTC) options positions. Like traditional exchange-traded options, FLEX Options are guaranteed for settlement by the OCC, a market clearinghouse that guarantees performance by counterparties to certain derivatives contracts. The investment process of the Funds investment adviser, Westwood Management Corp. (the Adviser) is designed to generate returns by investing in a portfolio of Midstream Investments. Returns are typically driven by the distribution yield, covered call premiums generated, growth in the underlying investments cash distributions and potential stock price appreciation, if any. The Adviser maintains proprietary business valuation models and analyses key variables such as cash flow stability, growth profile, commodity price sensitivity, balance sheet strength, hedging profile, management strength, competitive landscape and other factors. The Adviser employs a bottom up research-driven stock selection process with an emphasis on the opportunity set and growth prospects for each target investment. Changes in the laws of the United States, including tax laws and regulations, could result in the inability of the Fund to operate as described in this prospectus and the SAI and could adversely affect the Fund (see Tax Law Change Risk below). As a result of the Funds investment strategy, the Fund may engage in frequent and active trading. The percentage limitations applicable to the portfolio described above apply at the time of investment, and the Fund will review its holdings at least quarterly to confirm it is in compliance with its policy of investing at least 80% of its net assets (plus any borrowings for investment purposes) in securities of Midstream Investments. If during such review it is determined that the Fund has invested less than 80% of assets in securities of Midstream Investments, the Fund will be required to make future purchases of securities in a manner so as to come into compliance with this investment policy.
