Smartphone manufacturer BlackBerry has announced the departure of its chief financial officer, as well as two other top executives.
The news comes at the end of a difficult month for the company, in which CEO Thorsten Heins was reportedly forced to quit following a failed buyout bid from its main financial backers Fairfax Financial Holdings.
The latest shake-up of its top management, announced on Monday, sees Brian Bidulka replaced by James Yersh as CFO. Chief operating officer Kristian Tear and chief marketing officer Frank Boulben will also leave, with no replacements as yet announced.
"I thank Kristian and Frank for their efforts on behalf of BlackBerry," said interim CEO John Chen in a statement. "I also thank Brian for his eight years of dedicated service to BlackBerry. I look forward to working with James and his Finance team as we move forward, execute on our plans and deliver long-term value for our shareholders."
Chen hinted that there are still more management changes to come.
"In conjunction with these management changes," Chen said, "I will continue to align my senior management team and organizational structure, and refine the Company's strategy to ensure we deliver the best devices, mobile security and device management through BES 10, provide multi-platform messaging solutions with BBM, and expand adoption of QNX embedded systems."
It was also announced that Roger Martin, a Board member since 2007, has resigned. Board member Barbara Stymiest said: "Our Board has benefitted from Roger's expertise and insights over the past six years and we wish him the best."
Next month BlackBerry's quarterly results are due and forecasts suggest that the Ontario-based company's tumultuous year will be rounded off by another large loss.
