Mercury Interactive Corporation Proceedings. In November 2006, HP completed its acquisition of Mercury. Upon completion of the acquisition, HP assumed oversight for all litigation and regulatory matters pending or subsequently commenced against Mercury. Prior to the announcement of the acquisition, and beginning on our about August 19, 2005, four securities class action lawsuits were filed (all of which have since been consolidated into a single lawsuit) seeking unspecified monetary damages and other relief from Mercury and certain of its officers and directors for alleged violations of the federal securities laws. In addition, on February 26, 2007, HP received a request from the Permanent Subcommittee on Investigations of the U.S. Senate Committee on Homeland Security and Governmental Affairs for information relating to Mercurys past executive compensation and stock option granting policies and procedures, including information about the practice of backdating the grant date of options that allegedly occurred before HP acquired Mercury. The cost of defending such litigation and responding to the Senate inquiry may be significant. In addition, if we enter into settlement agreements or are subject to adverse findings in connection with such litigation, we could be required to pay substantial amounts in damages.
