2. By its resolution 71/311, the General Assembly appropriated an amount of $582,000,000 gross ($576,973,600 net) for the maintenance of UNSOS for the period from 1 July 2017 to 30 June 2018. Expenditures for the period totalled $571,498,500 gross ($564,813,500 net), reflecting a budget implementation rate of 98.2 per cent. The resulting unencumbered balance of $10,501,500, in gross terms, represents 1.8 per cent of the appropriation, reflecting the combined effect of: (a) lower-than-budgeted expenditures under military and police personnel ($5,814,000, or 3.4 per cent) and operational costs ($19,115,100, or 5.5 per cent); and (b) higher-than-budgeted expenditures under civilian personnel ($14,427,600, or 24 per cent). A detailed analysis of variances is provided in section IV of the report of the Secretary-General on the budget performance of UNSOS for the period from 1 July 2017 to 30 June 2018 (A/73/611).
