At the moment it is all rumours and conjecture, nothing more.
It is already being discussed within the BACC and, as always, I'm sure that the full picture and a truthful way forward will eventually be revealed.
From my experience this little 'leak' is a way of testing the markets to see how the stock prices react to such revelations. The last thing IAG want at the moment is to lurch from one crisis to another. I'm not even sure if the costs saved over the long term would be worth the potential costs involved with IA.
Will it happen? Who knows. It will be dealt with when the time comes. Not going to loose sleep over it that's for certain.
