Accordingly, effective on or about December 28, 2012 (the “Closing Date”), each Fund will be closed to any investments for new accounts, except that new accounts may be established for “sweep accounts” and by participants in group retirement plans (and their successor plans), provided the plan sponsor has been approved by The Dreyfus Corporation and established the Fund as an investment option in the plan before the Closing Date. Each Fund will continue to accept subsequent investments until the respective Liquidation Date, except that subsequent investments made by check or pursuant to Dreyfus TeleTransfer or Dreyfus Automatic Asset Builder ^® no longer will be accepted after February 20, 2013 with respect to the Money Market Series and after February 21, 2013 with respect to the Government Securities Series. However, subsequent investments by Dreyfus-sponsored Individual Retirement Accounts and Dreyfus-sponsored retirement plans (collectively, “Dreyfus Retirement Plans”) pursuant to Dreyfus TeleTransfer and Dreyfus Automatic Asset Builder ^® will be accepted after such dates. Please note that, with respect to each Fund, checks presented for payment to the Fund’s transfer agent pursuant to the Fund’s Checkwriting Privilege after the Fund’s liquidation will not be honored.

      Fund shares held on the respective Liquidation Date in Dreyfus Retirement Plans will be exchanged for Class 1 shares of Dreyfus Liquid Assets, Inc.
