GIPS Gross return and Net return

What change between the gros of fees return and the net of fees return?

And what is the custodial fees difference here?

net = gross - management fees

so that means gross includes ALL fees including trading expenses as well as custodial fees?

gross includes trading and the portion of bundled fees that can’t be seperated from trading expenses

Where are custodial fees? gross, net or none?

part of admin fees which can be included in wrap fees or not depending on if you can pull out trading expenses

so custodial should not be in either gross or net return?

it depends on the account type. if its in wrap fees that cannot be seperated from trading then yes its out of gross which means its also out of net

But if it is not in wrap fees? sorry but i just need a clear answer about the treatment of custodial fees and trading expenses and how gross and net return differentiate

then it wouldnt matter.
