Item 8.01 Other Events.

Kenneth T. Lamneck, President and CEO of Insight Enterprises, Inc. ("Insight"), adopted a pre-arranged stock trading plan on August 27, 2012 to sell Insight stock from vested restricted stock units. The plan was adopted in accordance with guidelines specified under Rule 10b5-1 of the Securities and Exchange Act of 1934 and Insight's policies regarding stock transactions. The transactions in this plan cover approximately 142,000 shares, will commence no earlier than November 1, 2012, will end no later than October 15, 2013 and will be disclosed publicly through Form 144 and Form 4 filings with the Securities and Exchange Commission. The Form 4 filings will also be posted on Insight's investor relations web site.

Rule 10b5-1 allows corporate officers and directors to adopt written, pre-arranged stock trading plans when they do not have material, non-public information. Using these plans, insiders can gradually diversify their investment portfolios, can spread stock trades out over an extended period of time to reduce any market impact, and can avoid concerns about whether they had material, non-public information when they sold their stock.
