Bluecollardollar: However why would you pay $1 a share when you could buy them on the open market for less?
That's true, but you won't be able to buy 6 million shares on the open market for $1 a share, not even on average.
At close on Friday you would have been able to buy only 339,500 shares in the 0.97 – 1.01 range, see http://apps.tmx.com/TMX/HttpController?GetPage=DelayedMarketByPrice&SelectedSymbol=PTK&Market=V&Language=en.
