NEW ORLEANS, LA--(Marketwire - March 26, 2009) - Kahn Gauthier Swick, LLC ("KGS") announces that a securities fraud class action lawsuit was filed in the United States District Court for the District of Arizona, on behalf of purchasers of the securities of Insight Enterprises, Inc. ("Insight" or the "Company") (NASDAQ: NSIT) between January 30, 2007 and February 6, 2009, inclusive (the "Class Period"). No class has yet been certified in this action.

Insight and certain of its executive officers are charged with violating the Securities Exchange Act of 1934 by issuing a series of materially false and misleading statements during the Class Period. On February 9, 2009, Insight shocked investors when it revealed that it would have to restate previously reported earnings as the result of improperly accounting for trade credits. Insight expected to restate for the year ended December 31, 2007 and the first three quarters of 2008. On this news, Insight shares fell $2.85 per share, almost 50%, to close at $3.05 per share on February 9, 2009. Thereafter, the Company disclosed that the SEC has requested documentation related to its historical treatment of trade credits.

If you wish to serve as lead plaintiff in this class action lawsuit, you must move the Court no later than 60 days from March 24, 2009. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member.
