The investment seeks to track the investment results of the MSCI USA Small Cap Extended ESG Focus Index. The fund generally will invest at least 90% of its assets in the component securities of the underlying index and may invest up to 10% of its assets in certain futures, options and swap contracts, cash and cash equivalents. The underlying index is an optimized equity index designed to produce investment results comparable to the MSCI USA Small Cap Index (the parent index), while reflecting a higher allocation than that of the parent index to companies with favorable ESG profiles (as determined by MSCI).
