Purchase info on Portfolio Section

Hi, if you go to your portoflio you will see a breakdown of your items, with stats beside such as:
Purchases: 98 (7.21 p/month)
Item sales: $1,032.14 ($73.72 p/month)
Support sales: $11.34 ($0.81 p/month)

Are these stats calculated after all fees are removed? So Item sales is total earnings, or is this a gross figure, without any deductions taken off?

Thanks!
