How do I determine the number of active Antivirus licenses within the Endpoint Protection environment

Under "Management" and then "Licensing", I can see that we have "Endpoint AntiVirus" enabled and active with a max user count of 105, but I cannot determine what percentage of the 105 licenses are actually utilized today?  Does anyone know how to find out this value of active licenses for Antivirus?

Thanks,
