TORONTO/NEW YORK, April 12 (Reuters) - BlackBerry plans to ask securities regulators in Canada and the United States to probe what it said is a "false and misleading" report that consumer return rates for BlackBerry's new Z10 smartphone have been especially high.
The Canadian company, which has pinned its turnaround hopes on its new BlackBerry 10 line of smartphones, went on the offensive on Friday after the report from Boston-based research and investment firm Detwiler Fenton sent its stock tumbling on Thursday.
BlackBerry said return rates for its flagship Z10 devices have been at, or below, its forecasts and in line with industry norms.
