Replying to [spider man]:
Are we now referring to Deferred Payment Credits?
Incidentally, if it is one thing I have learned in international banking - it is that nothing can be assumed. If the rules do NOT say that you CAN do something, it is risky to assume that you CAN. For, if you DO, you do not get the rules to support you or come to your rescue. In international banking (or even dealing with the regulators), it is always safer to be conservative. Unless the rules say you CAN you CAN'T. Simple!
