The fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities. It will typically invest in companies whose products and services are considered by the portfolio managers as contributing to positive environmental or social change and sustainable economic development. The fund generally invests in a core group of 50-70 equity securities, which consist primarily of common stocks, but may also include other types of instruments, such as depositary receipts and warrants.
