The PRs say United States Dollars (USD) not Canadian, so I am not sure why people are asking this question. ALso, the market cap and profile on Yahoo show approx 40,833,000 outstanding shares - not sure how you are getting over 400 million shares. The $9.1 million offer would indicate 91 million OS, so perhaps there are restricted shares that Yahoo is not picking up on or that only 40.8m have been issued.
The question I have is: are there any contingencies to the offer? The PRs do not mention any, thus I would say that this is a $9.1 million offer all cash and "as-is." Therefore, it accounts for whatever debts (loans) outstanding.
