Qantas737, your remark that the collapse of YC is in anyway related to the proposal by QF or SQ to increase stakes in NZ is absolute rubbish. In fact YC had gone into liquidation prior to NZ's board meeting being completed and an announcement made.
The competitive environment in regional Australia has meant that YC is unable to continue profitable operations. AN had absolutely no equity participation in YC. It was wholly owned by Dennis Buchanan. AN had a commercial relationship with YC only.
