You can beleive whatever you like....maybe it was simple incompetence, a typo as Clayton said in his email, but I'm not buying it.  I can't picture DM standing there and saying:

"Now on to slide 5, as it says we were founded in 2001, we trade on Canada's main TSX exchange.  Our market cap is around $155 million, but check your smart phones that may have changed a bit.  Our debt is, okay the slide says $117.6 million but that's a mistake, its actually $68.8 million....someone added almost $50 million, but that must be a typo...sorry about that".
