ok, let's just hope this will not develop into a vs. b, but as for your question, Klaus is absolutely right.
One more thing though:
Both manufacturers are now providing the chance to get out of firm orders, even losses, that result from selling aircraft, that were not accepted by the carrier that ordered it, way below order price (not list price!), go straight into the manufacturers p&l. Reason: What good is a receivable from a company that might just go belly-up, and even if it doesn't out of whatever reason, will never ever again order any aircraft from that manufacturer. So there are certain default clauses in the contracts, that leave the selling risk to a nd b.
I know it's only VfB but I like it!
