I think you might have the wrong end of the stick?
From what I can tell from BOA's market announcements the Sabre Fund basically uses BOA as a 'Custodian' who holds their holdings - the 'Return' and 'Borrowing' terms are just misleading!! But, I could be wrong.
Could you either check your facts or point me in the right direction? Certainly cloak and dagger stuff, but Sabre tend to do it will all their holdings (prime agreement). For instance check Resolute, Beach and Noble (OR Google search Sabre Fund Merrill) and you'll see what I mean.
