The Underlying Index is sponsored and maintained by Abacus FCF Indexes LLC (the "Index Provider"), an affiliate of Abacus FCF Advisors LLC, the Funds investment adviser (the Adviser). The Underlying Index is a rules-based equity index designed to track the performance of U.S. publicly traded companies with strong free cash flow return on invested capital (FCF-ROIC) and strong research and development (R&D) investment, as identified by the Index Provider through extensive historical research. The Fund intends to maintain a portfolio of securities that generally replicates the holdings of the Underlying Index. To be eligible for inclusion in the Underlying Index, an equity security must meet the following requirements (Eligible Securities): (i) be a U.S. listed common stock; (ii) have a minimum total market capitalization larger than the 97th percentile of the cumulative market capitalization of all Eligible Securities; (iii) have an average monthly trading volume of greater than $75 million over the last six months; and (iv) have been issued by a company that has reported over the past 12 months certain characteristics of its expenses, including free cash flow and positive R&D expense. The Underlying Index utilizes the Advisers proprietary Abacus FCF Leaders Model (the Model) to evaluate Eligible Securities and scores them based on FCF-ROIC. The Model assesses a companys FCF-ROIC by analyzing factors such as capital expenditure, accruals, cash flow margins, and asset turnover. The FCF-ROIC score is then combined with the degree of R&D investment to derive the FCF Innovation Leaders Score (the Score), which helps identify companies with strong and sustainable profitability and innovation. A target weighting is then assigned to each Eligible Security based on its Score, with adjustments for company-specific risk using a proprietary factor derived from the historical volatility of each Eligible Securitys stock price over the preceding 12-month period. The resulting risk-adjusted score is used to calculate active weights for each security, which are combined with their free-float market capitalization. The Underlying Index includes those remaining Eligible Securities until one of the following thresholds is met: (1) over 90% of the cumulative weight of the Eligible Securities has been included in the Underlying Index, or (2) the number of included securities reaches 50. The weights of all securities are then rescaled to construct the final portfolio, seeking to ensure high-conviction exposure to companies with strong and sustainable profitability and innovation. The Underlying Index is rebalanced and reconstituted quarterly, with a portfolio turnover cap of 25%. The Funds portfolio is generally rebalanced and reconstituted quarterly, in accordance with the Underlying Index. The Fund can use derivative instruments, including exchange-traded futures contracts, to gain exposure to component securities of the Underlying Index. The Fund will concentrate its investments (i.e., invest more than 25% of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of September 30, 2025, the Underlying Index is concentrated in the information technology sector. Show less
