Pick this option if they want to have a second FinRev account as a sub-account of their first account. They will have one login for both accounts. Best option for people who want to diversify risk across 2 exchanges.

Pick this option if you require a separate FinRev login with a different email address and separate financial records. Best option if you want to register a separate entity (e.g. company/401k/Superannuation fund)
