Forbes has a report on an Intel engineer, Roomi Khan who cooperated with the Fed´s to avoid charges in a wire fraud case back in 2001- 2002. Apparently Rajaratnam was making money from inside information even then.

“According to a June 2002 sentencing memorandum for Khan, the earlier case arose after Intel suspected Rajaratnam was getting tips from an Intel insider because he was predicting Intel’s revenue “with extreme accuracy.”

Intel set up a hidden video camera that on March 6, 1998, recorded Khan, employed as a product marketing engineer at the company, faxing an important report concerning Intel’s three main Pentium processors to Rajaratnam.

The memo said Khan on March 24 then faxed handwritten pages that contained pricing information and sales data for Intel chips. “By multiplying those numbers, one can determine Intel’s total revenue for the quarter,” it said.”
