Good question. Perhaps the answer lies in the title "forensic accountant". Perhaps they dug deep into every line item in GE's statutory reports, whereas most investors and the journalists that cover the markets only focus on the headline figures. It'll be interesting to see what comes out of this whatever the truth is.
I was reading some about this story and what I cannot figure out is how Harry Markopolos and his team got their information. They are not part of an official government organization, so they don't have subpoena power. How did they piece this together and nobody else did?
I don't really want to go through the 175-page report to figure it out. The guy was right about Madoff, so he certainly has some credibility.
