Well -certainly Ross was contracted to the team based on a schedule -and I imagine he receives the moneys from the sale to Daimler based on this schedule..
Last year it looked quite shaky for his future tbh and he nearly faced the chop but always insisted his future was in his own hands....but zetsche always maintaining firm committments were the basis of the original deal to buy into BrawnGP.
1+1 : Brawn will receive the final installment at the end of this year and can live very well without bagging a title which is not at all a certain deal at this time...
If Ross departure was not already looming quite a while why would the Paddy Lowe deal come so quickly....on the other hand I see Wolff having appetite for that and giving Lowe a Christian Horner like role...
