Calvert US Large Cap Growth Responsible Index Fund Class I 

This fund seeks to closely track its benchmark by holding common stock in every company represented in the underlying index, generally in proportions consistent with their index weighting. A significant portion, typically at least 95% of its total capital (including any borrowed funds for investment), will be dedicated to these index components. The index itself is comprised of shares from sizable, growth-focused businesses that conduct their operations in accordance with The Calvert Principles for Responsible Investment.
