Whatever happens, TAS will inevitably increase in value by a similar percentage to EDE, so I see no advantage in trying to swap over. But... as the market cap increases there is a very definite possibility that the asset backing will result in TAS appreciating faster than EDE.

AS R points out, those 2018 options on issue won't be allowed to expire. So at some stage TAS will probably need a capital raising, which will almost certainly be at a favourable discount. EDE may or may not have a further capital raising.

The only thing you really need to be concerned about really is the progress on completion of the Colorado plant and the GDOT deciding to use Edencrete on its roads, which I personally think is almost certain.
