There is a real debate to be had about how to apportion it absolutely and the balance between labour assets and sales, that is a fair point. It is also, however, clear that companies are able to take advantage of the fact that there is no common way of assessing corporation tax. I get the impression that Revenue and the Department of Finance have not made any assessment of the impact this would have on tax revenue. If the top 20 corporations paid 43% of corporation tax, presumably they all would be over the €750 million threshold. Presuming they were, have we an estimate of what that would cost the Exchequer?
