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 comprised of large and mid-capitalization companies in emerging markets countries that meet certain environmental, social and governance (ESG) criteria and/or have committed to greenhouse gas emissions reduction targets. The Underlying Index is then weighted in such a manner seeking to align its constituent companies greenhouse gas emissions with the long-term global warming target of the Paris Climate Agreement. Under normal circumstances, the Underlying Index is rebalanced semi-annually in February and August. The fund rebalances its portfolio in accordance with the Underlying Index, and, therefore, any changes to the Underlying Index's rebalance schedule will result in corresponding changes to the fund's rebalance schedule.
