Mr. John O'Sullivan:

Our structure changed from 2011 to 2016 and therefore we had to replenish it. Many people had left the organisation on foot of the various retirement programmes, etc. We had to replenish our capacity. As a result, we had an engagement with staff associations and unions which took longer than we had anticipated and this meant that the money earmarked for some changes in structure was not expended in that year. That was sorted by the end of the year and, throughout 2017, we ran a further recruitment programme. As a result of that, we have taken on additional staff. Ms Smyth will give us the details.
