Not really because you would conserve cash and then in presentations present the range of options available which would include doing nothing, because you could be unnecessarily investing.You do all those things to spruce the place up for a sale, I would guess the private equity knows at least roughly when they will sell. Spend now to show what it was like when they took over and what it is like now.
Virgin Australia isn't being put up for sale. The potential of an IPO which by the seems of it in the short term would be less than about 40% beause Bain want to maintain 51% plus I expect Virgin Group and QLD Government would maintain their small shares.
