Hoi,
First, there's an overview of 'highest paid contractors' (for reading along: page 61) and the top one is a law firm for 1.7 Million USD. Which is quite a big sum of money.
I'd like to second this question - 1.7M is a very significant sum and I am surprised that WMF has reason to spend this much on legal services (I had the impression that the WMF legal department handled most things themselves).
It would be useful to know a bit more about this figure.
Regards,
Chris
