Management commission
Also called: manager cut, management fee
Commission is normally taken off the gross, so the manager's cut comes out of a brand's fee before your costs and your tax. What it applies to is the part worth reading closely. Some agreements commission only the deals the manager brings in, others take a share of everything you earn while signed, including work you sourced yourself, and some keep running on renewals after the relationship ends.
That tail clause is the one that surprises people. Weigh the rate against the alternative, which is your own hours on outreach and negotiation plus whatever fee you can command unrepresented.
