Two points here:
1. You have told us nothing about this request, no context, no information of any sort.
2. Why do you want a powerpoint? What are you going to do with it. If it is to stand up in front of employees and just read the words on the screen with no context, no relationship to YOUR organisation, etc, then why waste the employees, and your time?
If there is some particular reason for this, then YOU need to design the presentation based on YOUR organisation, it's requirements, and structure, not someone else's.
