CF cannot accept Teck shares in exchange for a CF project. A company buy out is the only way Teck shares can be involved. I'm not against getting Teck shares, they are undervalued, and, if I need to I can sell and expose gains gradually over the years tax efficiently. But I challenge anyone to show me when Teck has ever issued shares to buy something.
If we have any chance at this, two conditions would have to be in place for a 'Teck shares in exchange for project(s)' approach. First, CF would have to spin out to CF shareholders a CF subsidiary that holds one or more projects to be sold. Then the the spun-out company is sold in exchange for Teck shares and then the distribution is pretty straight forward. Secondly, and unlikely though, Teck would have to be convinced that their share price is significantly overvalued in the transaction. And I know for a fact that Don thinks that their share price should be at all-time highs, which is north of $60.
