Calvert Research: Water Seen as Key Emerging Issue for Sustainable Investors; Newest Calvert "Solution" Fund Added in Wake of Calvert Global Alternative Energy Fund in 2007

On September 30, 2008, Calvert launched its latest sustainable and responsible investment (SRI) mutual fund, part of a new series of investment portfolios known as Calvert Solution(TM) Strategies. Calvert Global Water Fund (CFWAX) will be sub-advised by KBC Asset Management International, Ltd., of Dublin, Ireland, which boasts an eight-year track record of B performance in the global water sector. The unveiling of the new Calvert fund comes on the heels of the Calvert Global Alternative Energy Fund (CGAEX), which became available in mid-2007.

The Fund invests in utility, infrastructure, and technology companies active in managing water resources.

"We see B demand for such a fund from individual and institutional investors. We also see a tremendous opportunity to help educate investors on the societal concerns over ensuring equitable access to clean water and enable investors to be part of the solution," said Craig Cloyed, President, Calvert Distributors, Inc.

"The precarious global situation today related to the supply and demand for freshwater creates a significant need for substantial investment in sustainable methods of obtaining and delivering water," said Jens Peers, head of ECO Investing at Dublin-based KBC and lead portfolio manager of the Calvert Global Water Fund. "Calvert and KBC have an established relationship and a proven, successful track record in working together to manage the Calvert Global Alternative Energy Fund. KBC is a leader in the water investing field. We have been investing in water since 2000 through the KBC Eco Fund Water Strategy. KBC stays on top of the technological issues involved in the water cycle through its outside environmental advisory committee of scientists. We believe that no other water asset management group has set up a comparable committee of unbiased experts."

"Demand for water is rising around the world with both population growth and development. According to Scientific American 'Facing the Freshwater Crisis,' to provide access to water for these growing needs, there will need to be an investment of as much $1 trillion per year through 2030 in water infrastructure and sanitation systems," said Reggie Stanley, Senior Vice President and Chief Marketing Officer at Calvert. "Mutual funds and other investment vehicles are an important way to bring additional capital to the water sector. Currently, world-wide investments in water-related mutual funds and exchange-traded funds are over $13 billion.(1) In the face of this increasing demand for water investment, there is a growing awareness and interest from institutions and individuals in the investment and policy implications. Water is the ultimate natural resource. Some resources have substitutes. There are, however, no alternatives to water."

Calvert Solution(TM) Strategies consist of portfolios that selectively invest in companies that produce products and services designed to solve some of the most pressing environmental and social challenges. Generally, these strategies will seek to invest in companies that produce or market technologies that enhance the environment, public health and quality of life and in turn contribute positively to addressing U.S. and global sustainability challenges.

"As investors, we can apply our capital toward sustainable water-related technologies, services, and solutions," said Bennett Freeman, Senior Vice President for Social Research and Policy at Calvert. "Investors can encourage companies to manage their environmental impact responsibly by using less of this scarce resource and ensuring that communities have affordable access to clean water. With Calvert's significant research and analytical capabilities, as well as years of policy and advocacy experience, we are uniquely positioned to tackle the complex and sensitive sustainability concerns over water in a responsible way."
