Translating strateandlevel's best Belgrano-speak into English, the answer to Rev's enquiry is:
"There are no mandatory requirements for the physical presence of a FI to supervise a FI(R)"
So if there's a problem which casts doubt on the level of supervision being exercised at the time, just say that, as the CAA has failed to lay down any firm guidelines, the level of supervision seemed reasonable in your opinion.
PS, strateandlevel, could you ask GF to check his e-mails please!
