According to Wikipedia, that's 0.012% of their net income. [0] While I'm being told in the comments that this is not the way to look at it, it means that this is, percentage wise, 50x the amount that Google is paying.

Sounds fine to me.

//Edit: Had a typo in my percentage. 20.000 of 157.000.000 is, indeed, 0.012% - that makes it 50x the amount of Google's percentage.
