What does it pay to be the Pay Czar?

What is Kenneth Feinberg's annual salary? If anyone can figure it out, please post it on the following Wikipedia Page: http://en.wikipedia.org/wiki/List_of_United_States_Czars

This article says that he will "work for free" in the new position: http://www.whorunsgov.com/Profiles/Kenneth_R._Feinberg

I wonder, does the new Pay Czar consider "working for free" a "fair compensation" for his new job?

Does anyone really believe that he is going to work for free?
