If Dias is selling to someone, it must be shown on their book. However according to their most recent 10Q, 94.6% of their sales are in North America, 2.6 in Europe and 2.8% in Asia.
No matter how hard they try in Europe and Asia, we are not going to see much improvement to their bottom line in the next few years. And I don't think their have any advantages in competing in Asia and Europe at all, unless they want to change their current strategies and invest a lot of money into Asian and EU markets like they did in USA.
