The Financial Post reports in its Wednesday, Nov. 13, edition that Canadian securities regulators are preparing to enforce stricter guidelines for the cannabis industry after finding a series of inadequacies in the way companies disclose conflicts of interest, particularly when it comes to cross-ownership in mergers and acquisitions. The Post's Barbara Shecter writes that in some cases, regulators discovered that the buyer or seller in an M&A transaction had an undisclosed financial interest in the other company. "We have observed instances of inadequate transparency related to the cross-ownership of financial interests," including undisclosed business relationships, regulators from seven provinces including Ontario, British Columbia and Quebec said in a notice Tuesday. The new guidance requires cannabis companies to disclose such material information to investors in a variety of documents -- from prospectuses to takeover bid circulars, listing statements, and material change reports. Guidance from securities regulators lays the groundwork for enforcement action if companies do not adhere to the expectations that have been spelled out.
