With the UK tax figures for several companies including apple, where they only paid approx 2.5% in tax because most of the revenue recognition occurs in Ireland where they pay cheaper corporation tax, I guess this will have an impact for revenues for several companies going forward. Google are already in a dispute with France over this, and I would expect these tax loopholes to close int he future as Austerity hits the EU and each country looking for ways to boost tax income.
