Strategy [Heading]	Principal Investment Strategies
Strategy Narrative [Text Block]	The Adviser utilizes its proprietary Abacus FCF Leaders Model (the “Model”) to evaluate securities in the investment universe and scores them based on free cash flow (“FCF”) characteristics, including FCF profitability (the level of free cash flow a company generates relative to the size of its assets), FCF yield (free cash flow relative to the company's enterprise value) and FCF growth (the growth in a company's free cash flow over time). These securities are assigned active weights primarily based on their FCF characteristics, with adjustments reflecting the Adviser’s systematic evaluation of company-specific risk in the context of the business cycle. These active weights are integrated with free-float market capitalization weights and rescaled to construct the final portfolio, seeking to ensure high-conviction exposure to companies with strong FCF characteristics.
