Mr. Paul Quinn:

We will be examining how we measure this in terms of multi-year savings and current-year savings, because it comes back to the point about the impact on the budget in a given year. If one saves something once, one typically takes on that saving forever. From a budgetary perspective, when money comes out of the budget it generally does not go in the following year to come back out again. While the benefit persists, one takes it into account from a budgetary perspective only once. Returning to the standardisation of the methodology, we are going to examine how we measure those savings and over what period of time.
