SAN FRANCISCO AP – Facebook Inc. quickly concluded it wasn’t worth anywhere near the $15 billion market value implied in a 2007 investment made by Microsoft Corp., according to confidential information obtained Wednesday from court documents.

In a transcript of a June court hearing that was closed to the public, lawyers arguing over a legal settlement revealed Facebook’s own appraisal had priced its privately held stock at $8.88 per share, giving it a market value of about $3.7 billion.
