The Special Committee, if particular operational circumstances so require, on the basis of a proposal by the administrator, with the assistance of the operation commander, or by a Member State, may decide that the pre-financing and administrative management of certain expenditure in relation to an operation, while remaining the responsibility of the Member State which it concerns, shall be entrusted to Athena in order to facilitate the initial deployment of the forces to an operation, before participating Member States are confirmed. The management of these costs shall be assured within existing means and resources and the initial outlay capped at 20 % of the reference amount. In this case the Special Committee shall outline in its decision the modalities for pre-financing and reimbursement of the pre-financed amounts by the future participating Member States and third parties.
