Well, I guess it depends on the interpretation of the rules. The point of contention seems to be the valuing of assets, which of course FB has incentive to not value highly: > The IRS argues that Facebook understated the value of the intellectual property it sold to an Irish subsidiary in 2010 while building out global operations, a move common among U.S. multinationals. Ireland has lower corporate tax rates than the…
Part of the problem is, it’s not a legit, best price, arm’s-length, market price. Facebook:Ireland is just a sock puppet for Facebook:USA, and the latter has no intention of selling it to a true outsider. OTOH, if FB:USA sold the rights to FB:I for $1, knowing it would pay billions to license those rights the next year, I don’t get how that can be a proper valuation, even without a clear price discovery mechanism.
Suppose it costs $50M in salaries to create intellectual property which is then licensed to customers for $500M. Which one is the "market price"? It was sold for both prices, once by the employees to the company and then by the company to the customers. But the difference is a factor of ten.
More than that, the difference can be justified. When the $50M is paid, you don't know whether anybody will buy it. Maybe you'll make a billion dollars, or maybe you'll make nothing and just flushed $50M down the toilet. Or maybe you'll make a profit but the profits are spread over future years whereas the work was paid for immediately, so in an arms length market transaction you would expect the price paid to be discounted for the time value of money.
So they pay $50M for something they go on to sell for $500M. Which one is the market price? Both of them.
This obviously leaves more than enough slack for chicanery.
