The Galleon insider trading case reveals a world where corporate secrets are thrown around with cavalier disregard for regulations on how public company information should be disclosed.

But the Galleon scandal suggests there may be many in American business prepared to make a mockery of these efforts.

Prosecutors have charged six people, including billionaire Galleon Group founder Raj Rajaratnam, in the biggest hedge fund-related insider trading case in history. Rajaratnam was at the center of crisscrossing illegal information networks that brought more than $20 million in profit, according to the complaints. Among those entangled in the case are executives at several major companies, including IBM and Intel Corp; an executive at management consulting firm McKinsey & Co; an investor relations specialist; and a former Moody’s analyst.

Some of these executives are alleged to have passed on information relating to their companies’ earnings or deals, potentially violating the disclosure rule known as “Reg FD”.

Regulation Fair Disclosure was put in place in 2000 to prevent corporate executives from selectively disclosing information to analysts and investors.

The rules have led to an increase in regulatory filings when executives speak at conferences, ensuring that information disclosed by the executives is available publicly. But the Galleon case is raising questions about whether rules to control such behavior have any teeth. “Selective release of information is a violation of Reg FD.
