(5)In order to ensure that, if required, a CSD would be able to organise the restructuring of its activities or an orderly winding-down, a CSD should hold capital together with retained earnings and reserves that are sufficient, at all times, to withstand operational expenses over a period of time during which the CSD is able to reorganise its critical operations, including by recapitalising, replacing management, revising its business strategies, revising cost or fee structures and restructuring the services that it provides. Given that during the winding-down or restructuring of its activities, a CSD still needs to continue its usual operations and even though the actual expenses during a wind-down or restructuring of the operations of a CSD may be significantly higher than the gross annual operational expenses because of the restructuring or wind-down costs, the use of gross annual operational expenses as a benchmark for calculating the capital required should be an appropriate approximation of the actual expenses during the winding-down or restructuring of the operations of a CSD.
