Dear Advisor,

In addition to announcing our new offerings, we would like to highlight our Financial Advisor Directory, a unique marketing opportunity we provide to advisors that use our products. Through the Directory, potential investors are able to locate investment professionals in their local area. To take advantage of this service, please be sure to complete the Directory Release Form available on our Financial Advisor Center and return via fax, email or direct mail.

Current Offerings
Going forward, we will continue to offer five CUSIPs in order to provide investors with as wide a range of rate and term combinations as possible. As always, these offerings, as well as the latest news and updates, are available on our Financial Advisor Center at www.calvertfoundation.org/advisors.


Best,
Justin Conway Signature
