KSV Restructuring Inc., in a report filed Friday, said some non-binding offers would enable the deeply indebted companies to continue operating as viable businesses. More than 250 prospective purchasers and potential investors were sent so-called teaser letters and non-disclosure agreements advising them of the sale process, KSV says. The Halifax-based companies own daily newspapers in Nova Scotia, Prince Edward Island and Newfoundland and Labrador.
