This is also true. Back when I was drafting my then-company's Form 10-K annual reports, for just that reason I loaded up the risk section with a list of all the things that could go wrong, based on studying similar lists from the big software companies. It's sometimes known as vaccination or inoculation — "hey, we told you all these things that could make our stock price go south!"

(The danger with this approach, of course, is that if you inadvertently leave something out, the plaintiffs' lawyers will spotlight the omission and argue, "they LIED!")
