Eaton Vance Money Market Fund and Cash Management Fund filed a prospectus supplement to switch from "Prime" to Government money funds. It says, "On October 19, 2009, the Boards of Trustees of each Fund and Cash Management Portfolio, approved a change to the investment policies of each Fund and the Portfolio to provide that each will invest substantially all of its net assets in obligations of the U.S. Government and its agencies and instrumentalities. Implementation of this change is expected to be completed on or about March 1, 2010. In connection with the policy change, Eaton Vance Cash Management Fund will change its name to Eaton Vance U.S. Government Money Market Fund and the Portfolio will change its name to U.S. Government Money Market Portfolio. In addition, the Trustees approved the reorganization of Eaton Vance Money Market Fund into Class B shares of Eaton Vance Cash Management Fund. The reorganization is expected to be consummated on or about March 1, 2010." See also USA Today's "Savings rates change fast, but they don't go far".
