Yes, I agree with those calculations.
The O/S is 461mm. Of that, 159mm are newly minted restricted shares issued to new management (as former owners of Hannover House).
So, just netting those out the float would be 301mm.
However, there are restricted shares left over from before HH reverse merged into TDGI.
Per the Initial Company Information and Disclosure Statement, there were 57mm free-trading shares on Dec 1, 2009. Added to these are the 200mm. So, I get 257mm if no shares came off restriction.
Thus, the 269mm figure seems about right -- though 301mm is the upper bound even if all the pre-merger shares came off restriction.
