Only thing I can think of is that these were just purchase commitments and not actual orders like when you go to a website and checkout with a credit card. Then the sales would be booked into revenue when the EG was shipped/received by the customer and a bill was sent.
Could also have been contingency sales to distributors. If the distributors have a right to return any unsold goods whenever they please, then you can't take the EG into revenue until the distributor actually sells them.
