The fund, using a passive or indexing investment approach, seeks investment results that correspond generally to the performance, before fees and expenses, of the Underlying Index, which is a capitalization weighted index that provides exposure to companies with high environmental, social and governance (ESG) performance relative to their sector peers. The Underlying Index consists of large- and medium-capitalization companies in the US market. Under normal circumstances, the annual review of the Underlying Index takes place in May and it is rebalanced in August, November and February. The fund rebalances its portfolio in accordance with the Underlying Index, and, therefore, any changes to the Underlying Index's review and rebalance schedule will result in corresponding changes to the fund's rebalance schedule.
