Losses in 2013 are irrelevant if the forward projections are improving.
As for the money to build the stadium, from my understanding it was mostly converted into share capital and/or directors loans.
Any break even or profits will be after the interest is repaid on those loans. So therefore built into the profits and losses.
There are a couple of companies that will not make profits this year, but their share price will increase when the losses are published due to the market seeing the bigger picture financially.
Clubs like Saints have no share price as such and so only the clubs statement can be seen as a reflection of this
