Mr. Robert Watt:

There are two aspects to the single public service pension scheme. It is the gross estimate of the pensions. We have difficulty assessing the number of people who can retire at any given moment because for anybody who came in before 2012, the minimum retirement age is 60. Therefore, we never know in a given year the number of people who will retire. In any given year, there are 5,000 to 10,000 civil servants who could retire but we see that it is actually around 1,300, 1,400 or 1,500. It does not impact on the A.1. part of the Vote as it is ongoing spending but because the lump sums are paid, they have a big impact. If there are small differences in the number of people retiring in any given year, compared to our forecast, we have to pay out more for the lump sum. That is an ongoing challenge we have.
