I could be wrong about it but I'm just piecing together the media reports, considering they are written by journalists and not accountants - if the expectation for RA's share was $100m, and a $250m gross exceeded expectations, RA get around half that, debt is currently $64m, and they're talking a 'surplus' of $50m then $64 + $50m is $114m and is above the initial expectation of $100m. Normally I would assume that the surplus is RA's share of the revenue less the associated expenses, but $50m would be half the expectation, not exceeding it, so I'm just guessing that some journo's definition of surplus is the net take less the debt being paid off. Around $125m less $10m expenses sounds about right?
