FNDX uses fundamental screens (sales, cash flow, dividends, and buybacks) to scope out large companies from the broader FTSE Global Total Cap Index assessing company size using these metrics rather than market-cap. It then weights them accordingly. The top 87.5% of the companies by cumulative fundamental score are included in the index. The Index weights are determined annually in March but are implemented across the year rather than at one point in time to help increase investment capacity and minimize entry point risk. To do this, the index is divided into four equal segments and each of the segment is rebalanced on a rolling quarterly basis starting each March. FNDX`s underlying index changed its name from Russell Fundamental U.S. Large Company Index to Russell RAFI U.S. Large Company Index on December 1, 2016. There were no changes in index methodology and the resulting exposure.
