Despite an economic turnaround, Hewlett-Packard continues to be dogged by company scandals.

Barely a year and half after former CEO Carly Fiorina was ousted in February 2005, former chairman Patricia Dunn resigned from HP's board in September this year due to a spying scandal, making her the second high-ranking female executive to depart from the company. CEO and President Mark Hurd has been appointed by the board to take over for Dunn as chairman.

The Palo Alto, Calif.-based company, which is placed 11 on the Fortune 500, operates in more than 170 countries worldwide.

According to Gartner, HP regained its spot as the number one PC maker in the world for the third quarter of 2006, and the company's worldwide market share increased to 16.3 percent this quarter from 15.1 percent in 2005.

In the Asia-Pacific region, HP took second place with market share expanded slightly in the third quarter this year, from 12 to 12.9 percent due to sharp growth in notebook shipments.

This company is listed in Systems, Storage Management, Software Infrastructure, Business Applications, Networking & Communications, Security, Services.
