Mr. Cathal Masterson:

It is a fair question and one that is asked quite often. When those schemes are brought forward we are obliged to test them from a value-for-money perspective. There are four value-for-money tests, which means we have to test the scheme delivered through a PPP mechanism, where the PPP contractor will borrow to construct, operate and maintain the scheme and pay the cost of financing, versus the more traditional design-and-build model. It has to be tested through each of the phases and it passes the test for all our schemes in demonstrating value for money. That is perhaps a complicated explanation for the public. If the role were to be carried out in the traditional way we believe, through those tests and that quantification, it would be less beneficial to the taxpayer.
