The Policy:• provides guidance to assist in the identification of both personal and business conflicts;• sets out the requirement to clearly identify all conflicts and, if possible, take appropriate steps to avoid them;• where conflicts cannot be avoided, mandates that they be disclosed or recorded and effectively managed to mitigate any associated risk thata Group entity or employee might be, or perceived to be, unduly influenced as a result of their existence.

Mandatory Conflicts training is provided to all employees annually to ensure the provisions set out in the Policy are communicated, reinforced
and understood. To confirm their comprehension of the training, all employees must pass a test before being considered to have successfullycompleted the course. Any non-completion is subject to escalation to the Executive Committee.
