The fund provides exposure to US stocks of any size that meet specific ESG criteria. The fund excludes stocks from the S&P Composite 1500 Index, the parent index, that are involved in specific business activities, relevant ESG controversies, and against the principles of the United Nations Global Compact. Using a transparent, rules-based weighting system, the fund uses S&P DJI ESG Scores to overweight or underweight companies while maintaining similar overall industry or sector weights relative to the parent index. The index employs scaling factors that provide magnitudes of tilting that effectively controls how companies are overweighted or underweighted. The index rebalances on the last business day of April each year with quarterly updates to coincide with its parent index.
