A 2.5% concession is hardly 'life support'. It'll save GBG about $30m pretax on an annualised basis. Also its a 'once off', won't happen in year 2.
Just helps.
2.57 billion project with 1.78 billion in debt = 790m equity. Each own 50% = 395m equity each.
However note that debt includes the working cap. So book value is a lot higher.
