IFAC refers to the potential of an element of corporation tax receipts being unsustainable. I am just putting it back to our guestsnot in a wooly way but in a direct fashionand asking whether they have done an analysis of how much of that may be unsustainable. We have heard the range of €3 billion to €6 billion but is the true figure closer to the former or the latter?
