Calvert US Large-Cap Growth Responsible Index Fund 

This fund allocates its capital to the common equities of each company within its reference index, striving to maintain a proportional weighting similar to the index itself. Typically, a minimum of 95% of the fund's net assets—which can include borrowings for investment purposes—is committed to these index-listed securities. The underlying index is exclusively composed of common stocks belonging to large, growth-oriented companies that conduct their operations in a manner consistent with The Calvert Principles for Responsible Investment (the “Calvert Principles”).
