Green Century Balanced Fund

The investment seeks capital growth and income from a diversified portfolio of stocks and bonds which meet Green Century's standards for corporate environmental responsibility. The fund invests primarily in the stocks and bonds of environmentally responsible and sustainable U.S. companies, many of which also make positive environmental contributions. There is no predetermined percentage of assets allocated to either stocks or bonds, although the fund will generally invest at least 25% of its net assets in bonds and may not invest more than 75% of its net assets in stocks.
