Hewlett-Packard CEO Meg Whitman is assuming the title of chairman after the departure of interim chairman, Ralph Whitworth, who resigned to deal with health issues.
HP has split the roles of chairman and CEO since Mark Hurd resigned as CEO in 2010. The company has faced shareholder displeasure over a series of missteps and slumping sales. Whitworth, an activist shareholder, was named to the company's board to placate investors.
Whitworth announced his resignation on Tuesday.
