Strategy. The Fund may invest in any company whose securities are listed on a U.S. national securities exchange, including through American Depositary Receipts (ADRs), which are U.S. dollar-denominated securities of foreign issuers listed on U.S. national securities exchanges. The Fund intends to provide investment results that replicate the performance of the American Gas Association Stock Index (the AGA Stock Index). The AGA Stock Index is maintained by the American Gas Association, a national trade association of natural gas distribution companies, and is licensed exclusively to the Investment Manager for use as an investment strategy.

The Fund intends to provide investment results that replicate the performance of the American Gas Association Stock Index (the AGA Stock Index). The AGA Stock Index is maintained by the American Gas Association, a national trade association of natural gas distribution companies, and is licensed exclusively to the Investment Manager for use as an investment strategy. Calculated monthly, the AGA Stock Index consists of all member companies of the American Gas Association whose securities are traded on a U.S. stock exchange, which include natural gas distribution, gas pipeline, diversified gas, and combination gas and electric companies. The stocks included in the Fund are chosen solely on the basis of their inclusion in the AGA Stock Index. Under normal circumstances, the Fund intends to invest at least 85% of its net assets in the common stock of companies that have natural gas distribution and transmission operations, and no attempt is made to actively manage the Funds portfolio by using economic, financial, or market analysis. The adverse financial situation of a company will not result in its elimination from the Funds portfolio unless the company is removed from the AGA Stock Index. The percentage of the Funds assets invested in the stock of a particular company is approximately the same as the percentage weighting of such company in the AGA Stock Index. The percentage weighting of each company in the AGA Stock Index is an amount equal to such companys market capitalization multiplied by the percentage of such companys assets devoted to natural gas distribution and transmission. The latter component of this calculation is used to recognize the natural gas distribution and transmission component of the companys asset base. There is no predetermined acceptable range of the difference between the total return of the AGA Stock Index and the total return of the Fund. Any difference is likely the result of various expenses incurred by the Fund, such as management fees, transaction costs, and other operating expenses, as well as subscription and redemption activity. On the other hand, the Fund does attempt to achieve a correlation of monthly returns with the AGA Stock Index of approximately 95% or better. A correlation of 100% would mean the total return of the Funds assets would increase and decrease at exactly the same rate as the total return of the AGA Stock Index. Show less
