Don't know the number they have affixed (laziness on my part), but to have the cash back in our economy is a good thing. An example would be:
Does US dollars sent back to Mexico by whomever help the US or Mexican economy?
My thought is, Why is a multinational concerned where the cash is? I'm not a corporatist, multinationals hold no allegiance to any nation. I say let them bring the money back with no tax, it's already been taxed in the country it was earned in. I personally don't think much will be repatriated, they already do business in those nations. We'll see.
