My take is that the funds invested by Qantas were more than the mooted 99 million each. There was no disclosure from the Chinese partners about their funding sources, for example. I have heard it whispered that Qantas issued non-recourse loans to their Chinese partners to fund their share.
If you look at the half yearly report, QF added 7 unencumbered A320's to the books. Just so happens that at the time there were 7 Jetstar HK A320's sitting outside the Airbus factory.
No doubt it was not these actual A320's, after all it's a three way partnership, but perhaps a "different" set of 7 were fully paid for by QF. Problem solved!
