I think the points above are quite comprehensive in describing these issues and how to address them. In my experience, from a practical point of view, it may be difficult to achieve an understanding of the differences, due to reasons such as language barriers, or business culture/approach (e.g. conservative, indirect, target company executives who are not used to saying whats on their mind). Further, the legal requirements in some jurisdictions may not be as clear as what the acquiring company is used to in its own jurisdiction, so additional time must be set aside for relevant authorities to get back to you on say, licenses, permits, but in my experience, sometimes a clear answer is never given. Perhaps buyers must go in with eyes wide open, and perhaps leverage on price to take into account these risks.
