I don't have access to the original Privco report, but this article on Time http://goo.gl/iu1z3 cites it as saying the 178 employees are dvying up $66 million among themselves and goes on to say a couple of sentences later that the first 30 employees average out to $3.6 million... which adds up to $108 million.

Anyone with a basic understanding of math ought to recognize that their numbers are dubious. It's disappointing to see it echoed all over the web including publications like Time who should be expected to do some simple fact checking.
