The Calvert Growth Allocation Fund operates as a multi-manager portfolio, seeking to achieve its financial objectives by primarily distributing its capital among various underlying Calvert-managed funds. These subsidiary portfolios focus on both fixed-income and equity investments, all while adhering to the fund's specific selection criteria, which notably incorporate its responsible investing principles. Regarding asset distribution, the fund characteristically dedicates a significant majority—between 80% and 100%—of its net assets to funds primarily invested in common equities. A smaller portion, up to 20% of its net assets, is typically directed towards funds that concentrate on income-generating securities. Additionally, the fund maintains the flexibility to hold a minor percentage, ranging from 0% to 10% of its net assets, in highly liquid instruments such as cash and short-term money market funds.
