(Telecompaper) BlackBerry would consider exiting its handset business if it remains unprofitable, CEO John Chen said. "If I cannot make money on handsets, I will not be in the handset business," Chen said in an interview with Reuters, adding that the time frame for such a decision was short. He would not be more specific, but said it should be possible to make money off shipments of as few as 10 million a year. Chen said BlackBerry remained on track to be cash-flow positive by the end of the current fiscal year, which runs to the end of February 2015, and to return to profit some time in the fiscal year after that. The company's focus remains on its core business customers, as well as associated services targeting secure communications and connected devices. Chen, who took over as CEO last November, said BlackBerry was also looking to invest in or team up with other companies in regulated industries such as healthcare, and financial and legal services, all of which require highly secure communications. Small acquisitions to strengthen BlackBerry's network security offerings were also possible, he added.
