RBS made an operating profit of ÂŁ3.1bn, the losses were associated with them taking a charge against the value of their own debt (a new and very stupid regulation from the EU). Sure a ÂŁ5bn loss makes for a nice headline and it sells newspapers, but the reality is that RBS are formidably profitable once again.
Well they are paid out on annual performance targets so by October most people know what kind of bonus they are in line for. Also, most bonuses are paid on personal performance, not group level performance. If the risk division fuck up and lose the bank ÂŁ10bn is it the fault of the investment division who bring in ÂŁ5bn in profit?
If I were to perform poorly I would not get a bonus, it's quite simple. If I perform well and bring money in I will get what I am contractually obliged to, regardless of whether group performance is good or bad.
It's not a tax wheeze, trust me. Bonuses are taxed as regular income. It's a nice money spinner for the government.
