Executives from Microsoft introduced The SCO Group to an investment fund that provided the Lindon, Utah, company with a $50 million investment last October, a spokesman for the fund confirmed Thursday.Microsoft executives talking to BayStar Capital suggested the investor should look into SCO as an investment opportunity, said Bob McGrath, a BayStar spokesman. "BayStar was introduced to SCO by executives at Microsoft," McGrath said. "We talk to individuals all the time about investment."SCO claims that the Linux operating system contains code that violates its intellectual property rights, and it has launched lawsuits against IBM\u00a0and Novell in connection with those claims.Microsoft, whose Windows operating system monopoly is threatened by Linux, has paid SCO in the past. A 2003 Unix licensing deal between the two companies earned SCO $16.6 million last year, according to U.S. Securities and Exchange Commission (SEC) filings.The software giant's role in the BayStar financing, however, had been unknown until recently. It first came to light last week, when open-source advocate Eric Raymond published an e-mail written by Mike Anderer, a consultant with SCO contractor S2 Strategic Consulting that appeared to suggest that Microsoft had funneled as much as $86 million into the company."Microsoft also indicated there was a lot more money out there and they would clearly rather use BayStar 'like' entities to help us get signifigantly [sic] more money if we want to grow further or do acquisitions," the e-mail said.SCO confirmed the authenticity of the Oct. 12, 2003, e-mail, but dismissed its contents."We believe the e-mail was simply a misunderstanding of the facts by an outside consultant who was working on a specific, unrelated project to the BayStar transaction. He was told at the time of his misunderstanding," a SCO spokesman said last week.While he did not find it surprising that Microsoft had not made a direct investment in BayStar, Raymond speculated that the SCO investment probably involved "an unspoken quid pro quo that would be difficult to verify," on the part of Microsoft."They're admitting the most innocuous parts of the truth in the hopes that no one will press them to disclose the really juicy stuff," Raymond said Thursday, suggesting that more disclosures on the relationship between Microsoft and SCO could emerge should SCO be investigated by the SEC.So far Microsoft's investment tip has not proved to be a good one. BayStar purchased stock in SCO for $16.93. With SCO's stock trading at $9.66 on Thursday, that means BayStar's initial $50 million investment is now worth $28.5 million.Microsoft and SCO declined to comment Thursday.
