They did know. I'm pretty sure the even put aside money to pay the taxes. Obviously, they don't intend to keep the money sitting around doing nothing forever. What the didn't know is that the EU would force a claim on money that they intended for their U.S. corporation.Not going to be taking advantage of it much longer. Only two things certain in life, death and taxes.
They should have known this would catch up to them eventually.
Correct. That's what they appear to believe.The first paragraph of the EU briefing notes that Ireland gave selective treatment to Apple, allowing it to pay substantially less than others. The Commission appears to believe that what you are saying is not the case.
But their argument seems to be that since Apple and a few other companies were uniquely set up to take advantage of the rulings that applied to everyone, that is the same thing as a selective treatment. Apple disagrees based on the fact that anyone could take advantage of the same rules by changing their corporate structure.
