Mr. Brendan McDonagh:

The criteria are effectively based on a financial calculation where one works out the net present value of getting the money today versus getting it at a future date over a number of years. One has the attendant risks in terms of what can happen in that regard. That is what it comes down to in each individual case. In addition, the board could take a strategic decision on an asset in a certain market to which it no longer wants to be exposed. Generally, it is very much a commercial decision.
