On the one hand, the departure of highly available members of staff, led to de facto under-consumption. Moreover, the number of inspection missions and the length thereof contribute to the total amount of funds required to repay the salaries of external staff. This is difficult to foresee at the beginning of the year, since the places to be visited are only scheduled a month in advance. Finally, use of retired members of staff is variable according to their respective personal commitments. Moreover, it should be emphasised that the limits set by the decision (arrêté) of 13th November 2008 do not make it possible to repay the salaries of external staff for inspections of more than 9 days in length. Steps were thus undertaken in the final quarter in order to make an amendment to this regulation, so as to enable payment for the work actually done by staff. This package of funds is essential to the operation of the institution since it makes it possible to ensure the flexibility needed in order to adapt the size of teams to the requirements of inspections. 4.2.2 Funds excluding internal Staff Costs 81% (€1,271,105) of the funding commitments (AE / autorisations d’engagements) were consumed and 75% (€748,067) of the funding appropriations (CP / crédits de paiement). A special feature of this year needs to be emphasised: on the one hand, the transition connected with the change of Contrôleur Général reduced commitments (only emergencies and costs strictly necessary to the operation of the institution were laid out), and therefore consumption, for a period of around one month. On the other hand, the renegotiation of the lease in December, made it possible to return to the 2008 cost of rent. The funding appropriations were principally devoted to three types of expenditure: rent, travel costs and normal operating expenditure. 79
