With two or more payees, the account must identify the construction contracts or indicate that it is for all contracts under which the payee holds retention money. Also, the bank must know that this is retention money. That's, again, an important part, because there may come a time when this company or the payer does go broke or comes into financial difficulties, and the first thing the bank is going to do, obviously, is protect its asset. This way, the bank will know what is retention money and, therefore, that will not be part of the security because, essentially, it is not theirs to take in the event of the company going broke. As far as practicable in the accounts, the bank is required to actually ensure that that's identified—as they are. So, in the end, it does dig down quite deep into the detail, but, obviously, it needs to do so.
