Dear Valued Shareholder,

Boston Trust Walden Funds would like to remind you of a change to the log-in process for accessing your accounts. The upgrade is being made as part of our commitment to provide you with convenient and secure online information about your investments.

Effective October 2016, a one-time password (OTP) will be introduced to provide an additional layer of security for user access. You will continue to use your current user ID and password once the upgrade is made, however upon successful log-in you will be required to enter a one-time password (OTP) that will be sent to your email address. The OTP will be valid for 5 minutes. You may elect to register your device as part of entering your OTP which will allow access without an OTP for 60 days unless you log-in from an unregistered device or erase your browser cookies from your registered device.

As part of our on-going efforts to improve the services available to our shareholders, Boston Trust Walden is pleased to introduce our new and improved on-line access site. Please follow these simple steps for both new and re-registration:

• Select the Register Now link below
• Enter your account number. To locate, the field labeled 'Account' on the second page of your account statement contains your account number. The account number is the series of digits between the dashes. For example, 123456789 would be the account number for Account 185-123456789-53. If your statement consolidates multiple accounts, you may select any one of the account numbers provided on your statement.
• Enter your Social Security Number
• Select the Register button
• Follow the instructions to establish your User ID, PIN, and account preferences.
• For your security you should change your password every 90 days.
