Apple has the biggest stockpile of cash any company has ever created: around $250 billion. Most of it is overseas. Even if they bring this money back to the US after paying taxes on it, they'd still be left with a lot. In fact, Apple would have enough cash-on-hand to buy pretty much any other company in the world (if they also use leverage). They may decide to acquire another company.
If you were Tim Cook, were the head of Apple and absolutely had to do it, which company would you acquire?
