Mr. Colin Bray:

The SLA is not about making up the difference; it is around value for money in relation to that SLA. It is not there as a mechanism to cover a shortfall. We run ourselves as a commercial operation, and that would be one element of the funding. It is my responsibility to manage that bottom line as in bringing in additional commercial revenue and reduce operating costs. The SLA is only one part of our funding model but it is not there to bridge a shortfall; it is there as a legitimate activity for national interest work that would not be undertaken by another organisation. In managing the bottom line, that is within our control and that is our responsibility.
