Lehman Brothers was fined $400,000 (€311,000) by NYSE Regulation for submitting inaccurate monthly reports on the company's short-interest positions.

Lehman misreported its short-interest position in a number of stocks for more than three years, according to the regulator. Lehman misreported an average of 4.23 million shares a month between January 2001 and May 2004. NYSE Regulation said Lehman's reporting errors caused 4,000 errors in NYSE short-interest reports and ruined the exchange's monthly reports.
