TORONTO (TIP): BlackBerry founders Mike Lazaridis and Douglas Fregin are weighing taking over the distressed smartphone company as it searches for a savior. Lazaridis said on Thursday in a filing with the Securities and Exchange Commission that he and Fregin are looking to potentially acquire the 92 percent of the shares they don’t currently own, either by themselves or with other interested parties. They have hired Goldman Sachs and Centerview Partners to help them explore options. The filing said Lazaridis and Fregin own 8 percent of BlackBerry. Their announcement is the latest sign of investor interest in BlackBerry after the company launched a review to consider a possible sale or break-up of its operations. The Canadian company announced last month that Fairfax Financial Holdings Ltd., which owns close to 10 percent of the company, signed a letter of intent that “contemplates” buying BlackBerry for $9 a share, or $4.7 billion. Fairfax, BlackBerry’s largest shareholder, is trying to attract other investors.
