Mr. Dean Sullivan:

Mr. Reid has mentioned the 2008 review, which concluded that an operational lease is the most cost-effective solution. As Mr. Curran may elaborate in a second, it is not always possible to enter into such a lease. We may wish to put a primary care centre in a particular location through the operational lease model, but it becomes problematic to do so if we cannot attract interest locally or we cannot identify a site locally. That conclusion was reached in the review. We intend to undertake a cost-evaluation exercise next year. This will be informed by the guidance of the Department of Public Expenditure and Reform. We will explore the three different modes or models of delivery again to see which of them is the most appropriate in today's circumstances. Of course we will look at that. The models we have on the ground now reflect that fact that there is no one right solution. Each of them has strengths and weaknesses. Perhaps Mr. Curran would like to add some light and shade.
