The fund goes for value exposure within the US mega-cap space, selecting companies according to several value factors, including book-to-price, forward and historical earnings-to-price, dividend-to-price and sales-to-price ratios. Securities are scored and ranked based on the composite score of these five value factors, which is also the basis for their weighting. The resulting portfolio is a very representative take on the large-value space. The index is fully reviewed on a quarterly basis.
