Mr. Seamus McCarthy:

There is an overview chapter in last year's report which gives a high-level view of what is under way. I have also drawn attention to some cases in which outturn was not exactly what was expected. We have not carried out a specific in-depth review of individual projects in recent years but I do want to do some work on that in the future. I believe I gave a note to the committee in the past in respect of the work that had been done and the issues which had arisen from it.
