During financial year 2006-07, the percentage of the total gross operating costs, excluding interest, of the UK Hydrographic Office trading fund (i.e. excluding its non-public sector subsidiaries), was:
2.49 per cent. for travel and subsistence expenses;
and
1.26 per cent. on marketing events and publications.
For the purpose of this reply it has been assumed that publications relate to promotional materials, as opposed to the cost of navigational publications produced by the UK Hydrographic Office for sale.
