The Fund is an exchange-traded fund (?ETF?) that employs a passive management or indexing investment approach designed to track the total return performance, before fees and expenses, of the Index. The Fund seeks to invest in the Index components in approximately the same weighting that such components have within the Index at the applicable time. The Fund may purchase a sample of securities in its Index. There may also be instances in which the Adviser may choose to underweight or overweight a security in the Fund?s Index, purchase securities not in the Fund?s Index that the Adviser believes are appropriate to substitute for certain securities in such Index or utilize various combinations of other available investment techniques. The Fund may concentrate its investments (i.e., hold more than 25% of its assets) in a particular industry or group of industries to the extent that the Index is concentrated. The degree to which components of the Index represent certain sectors or industries may change over time. The Index and the Fund are concentrated in the oil and gas industries. THE FUND IS NON-DIVERSIFIED UNDER THE INVESTMENT COMPANY ACT OF 1940, AS AMENDED, AND MAY INVEST A LARGER PERCENTAGE OF ITS ASSETS IN FEWER ISSUERS THAN DIVERSIFIED FUNDS. INFORMATION ABOUT THE INDEX The Index is an economic-value weighted index providing exposure to companies that extract oil and gas within Texas. Each company in the Index must be a publicly traded constituent of the VettaFi Global Developed 5000 Index and responsible for more than 0.1% of the annual state oil and gas production of Texas over the past 10 years based on data published by the Texas Railroad Commission. The creation, construction and maintenance of the Index is provided by VettaFi, LLC (?Index Provider?), a separate company with separate personnel that is unaffiliated with Texas Capital. As of March 31, 2025, the Index included 28 companies with the market capitalization ranging from approximately $230 million to $516 billion. The composition of the Index is then further defined by the following parameters: Weighting The weighting of issuers in the Index will be determined based on the ?aggregated economic value? of oil and gas production in Texas relative to the value within the Index and subject to the requirements applicable to regulated investment companies under the Internal Revenue Code of 1986, as amended. A company?s aggregated economic value of oil and gas produced in Texas is calculated by aggregating the oil and gas production of the company and multiplying it by the average oil and gas futures prices from the last day of February in the current and previous year. The maximum single security weight will be 10%. Reconstitution and Rebalancing The Index will be reconstituted annually and rebalanced quarterly, with index composition and related weight adjustments taken as necessary following extraordinary events (such as delisting, bankruptcy, mergers or takeovers of index components, stock splits, consolidations, or other corporate actions).
