(1) A payment order is "executed" by the receiving bank when it issues
a  payment order intended to carry out the payment order received by the
bank. A payment order received by the beneficiary's bank can be accepted
but cannot be executed.
  (2) "Execution date" of a payment order means the  day  on  which  the
receiving  bank  may  properly issue a payment order in execution of the
sender's order. The execution date may be determined by  instruction  of
the sender but cannot be earlier than the day the order is received and,
unless  otherwise  determined,  is the day the order is received. If the
sender's instruction states a payment date, the execution  date  is  the
payment  date  or  an  earlier  date  on  which  execution is reasonably
necessary to allow payment to the beneficiary on the payment date.
