A shareholder lawsuit against HP for attempting to spy on board members and reporters has been expanded to include charges of insider stock trading.
An amended complaint, filed on Wednesday in the Superior Court of California for Santa Clara County, accuses HP chairman and CEO Mark Hurd and seven other company executives of selling HP stock worth $41.3m (about £21m) at "inflated prices" shortly before the company revealed that its investigators had used questionable and possibly illegal techniques to gain access to personal records such as phone call logs.
The eight executives sold 1.7 million shares of stock between 21 August and 6 September, according to the lawsuit. In a 31 August filing with the US SEC (Securities and Exchange Commission), HP said an outside investigator used the practice of 'pretexting' (pretending to be someone else) to gain access to personal records.
Former HP chairman Patricia Dunn and four others face criminal charges stemming from their alleged participation in the spying, which also used email tracer technology, according to testimony before a US congressional committee.
The lawsuit also says HP tried to prop up the value of its stock price by announcing on 21 August that it would repurchase $6bn (£3.05bn)-worth of its stock.
"In the midst of this acrimony HP executives cashed in," says the complaint, filed by the Lerach, Coughlin, Stoia, Geller, Rudman & Robbins LLP law firm.
HP issued a statement calling the lawsuit "baseless". The lawsuit "represents a transparent effort to exploit issues related to HP's recent investigation for personal gain at the expense of HP, its shareholders and its employees", the statement read. "HP will defend itself vigorously."
HP acknowledged that it had obtained the phone records of 12 people by using pretexting.
The stockholder lawsuit, originally filed in September, asks the court to declare that HP's executives have "committed breaches of their fiduciary duties" and to order executives to repay the amount the company has been damaged by the spying scandal. The lawsuit also asks the court to require HP to reform its corporate governance and to extract punitive damages from Dunn, Hurd and other company executives.
