TORONTO, Nov 25 (Reuters) - BlackBerry Ltd said on Monday that two top executives were departing and a third was replaced in a widely expected shake-up following this month's naming of a new chief executive, and that more changes were coming.
The troubled smartphone maker, based in Waterloo, Ontario, said Kristian Tear, its chief operating officer, and Frank Boulben, its chief marketing officer, will leave. James Yersh will replace Brian Bidulka as chief financial officer.
BlackBerry also said Roger Martin, a board member since 2007, has resigned.
Early in November, BlackBerry said it had shelved plans to sell itself and instead opted to raise $1 billion via a convertible notes offering led by Fairfax Financial Holdings Ltd , its largest shareholder.
As part of the deal, the company also announced John Chen as interim CEO, replacing Thorsten Heins.
Chen, who helped turn around software maker Sybase in the late 1990s, told Reuters in an interview earlier this month that he would change management, hiring from outside the company and also promoting from within.
BlackBerry said new CFO Yersh has worked at the company since 2008 - as senior vice president, controller and head of compliance.
"I will continue to align my senior management team and organizational structure," said Chen in the statement on Monday.
