The new custodial balance confirmation period begins on July 2, 2025.

Dear Participants,

The Supervisory Committee informs you through DCV that we will soon begin the new process to confirm custodial balances on July 2. This is a quarterly process mandated by the DCV Supervisory Committee, with a deadline of July 25, 2025.

Please note that users executing this task must have their corresponding roles assigned. The security administrators of each participant are responsible for assigning these roles.

The access credentials for this platform are the same as those for the DCV Evolution (DCVe) platform. The security administrator must create and assign access credentials, manage users, and unlock passwords.

Users will be able to do the following based on the profiles assigned:

• Check available balances if they only have view access.
• Approve and reject if they have been assigned privileges that allow for these actions.

For more details, please refer to the application’s operational manual. It includes a description of requirements and step-by-step instructions.

The process for confirming equity, fixed income, or financial intermediation issuances will continue through letters sent by the auditors of the Supervisory Committee.
