Two main bidders for Stansted after Australasians pull out - Telegraph
This could be bad news for BAA, but better for STN's future if it reduces the eventual price paid. Interestingly, the requirement to make the deal 'investment grade' is £500m equity (= money) to £500m loans. This high hurdle is due to the dominance of one carrier (Ryanair with 70% of the current throughput) and the fact that STN is regulated.
