Ann: Investor Presentation and Investor Meetings, page-33

no - not joking at all.
It's a power point presentation with what?.....a small spelling mistake?...I'm sure there's probably other spelling mistakes or whatever elsewhere in the presentation....so what? I've seen much worse
It is only a power point presentation probably put together by the secretary for show & tell to potential investors - I'm sure a simple spelling mistake would not put them off the actual product.

It is not a power point presentation to the FDA. So long as they get the instructions right for FDA - that's all that matters in my opinion.
