Here is a link to McCarthy's summary regarding some of the rules for acquisitions of a Canadian listed company. Some interesting points given Pinetree and IBKs holdings. Also if you were one of the interested parties. I worked for a company that was a targeted unfriendly acquisition. the acquiring company initially bought a couple of 1000 shares and then continued to nibble. The corporate secretary had NOT watched the shareholder listings or ownership. They nibbled up to 2% before they were noticed or made the offer. It got pretty messy but eventually the company got bought. Wouldn't the companies who have an interest in acquiring POET already own shares and start the process of getting more up to the legal limit?
