Regulators Reviewing CSFB Direction to Purge Certain E-mails

Regulators are reviewing an e-mail sent by investment bankers at Credit Suisse First Boston reminding the firm's technology bankers to purge certain e-mails and other documents, as the securities firm braced for investor lawsuits over IPOs whose stock prices had tumbled, according to people familiar with the matter. The e-mail, dated Dec. 4, 2000 -- which included a reply endorsing the advice from star CSFB technology investment banker Frank Quattrone -- doesn't mention government regulatory probes of initial public offerings.
