What are fee-paying discretionary portfolios ?

Hi all, What are fee-paying discretionary portfolios ? Why they have to be included in GIPS? Does non discretionary portfolio also exist and they do not form part of GIPS? S

I think I had read somewhere that both “fee-paying” discretionary & non-discretionary portfolios have to be included in a composite that claims GIPS compliance… Pls correct me if I am wrong…

Keep in mind that, according to GIPS, you must disclose if you include non-fee paying discretionary accounts with the fee paying accounts in your composite.
