Financial Strategy

The Green Century Equity Fund's objective is to achieve long-term total return which matches the performance of the MSCI KLD 400 Social Index (formerly named the Domini 400 Social Index), an index comprised of the stocks of approximately 400 companies selected using environmental, social and governance criteria. The majority of these companies are included in the Standard & Poors 500^_® Index and allow for a diversified investment in environmentally sound businesses.

Sustainability Strategy

The Green Century Equity Fund screens companies according to their environmental, social and governance performance. The screening criteria includes, but is not limited to, the following factors:

Environment	Social	Governance
· Efficiency of resource use	· Impact on community	· Sustainability reporting
· Management of waste and emissions	· Product quality and services	· Ethical business practices
· Environmentally beneficial products and services	· Fair labor practices, including respect for human rights	· Political accountability

Certain industries may impose unique and onerous risks and/or costs on society. Therefore, companies with significant business involvement in the following industries will not be included in the MSCI KLD 400 Social Index: alcohol, tobacco, firearms, nuclear power, military weapons, and gambling.

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating™ based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) The Overall Morningstar Rating for a fund is derived from a weighted average of the performance figures associated with its three-, five- and ten-year (if applicable) Morningstar Rating metrics. As of 3/31/13, the Green Century Balanced Fund was rated against the following numbers of U.S.-domiciled moderate allocation funds over the following time periods: 802 funds in the last three years, 697 funds in the last five years, and 414 funds in the last ten years. With respect to these moderate allocation funds, the Green Century Balanced Fund received a Morningstar Rating of 3 stars, 3 stars and 4 stars for the three-, five- and ten-year periods, respectively. As of 3/31/13, the Green Century Equity Fund was rated against the following numbers of U.S.-domiciled large growth funds over the following time periods: 1482 funds in the last three years, 1278 funds in the last five years, and 856 funds in the last ten years.
