The figure for net non-capital supply services in 1999 published as part of the multi-annual presentation of the 1998 budget represents the projected cost in 1999 of maintaining the existing level of programmes and services as provided for in the expenditure estimates set out in the 1998 Abridged Estimates Volume adjusted for changes announced in the budget i.e. a "no policy change" projection of spending in 1999.
Since the budget, a number of additional cost pressures have emerged, most of which have arisen due to estimating or technical factors, for example, in the case of certain demand led schemes and programmes. Where the Government has taken decisions involving additional cost, it has sought, in so far as possible, to meet those costs from within the existing allocations and thereby minimise the impact on the multi-annual no policy change costings published in the budget.
