The fund is a "fund of funds" that seeks to achieve its investment objective by primarily allocating its assets among underlying Calvert income and equity funds meeting its investment criteria, including the responsible investing criteria. It typically invests 80%-100% of its net assets in funds that invest primarily in equity securities and up to 20% of its net assets in funds that invest primarily in income securities. The fund may also invest 0% to 10% of net assets in cash and short-term money market instruments.
