When a vehicle is assigned to an employee, it is assigned a value, known as the TCO (Total Cost Ownership) value. The amount of the Mobility Credit is calculated according to the TCO value of the said vehicle. It is then the cost of this vehicle that is replaced:
1. In case of total renunciation, the amount of the Mobility Credit, corresponding to the TCO value of the old vehicle.
2. In case of partial renunciation, the amount of the Mobility Credit, corresponding to the difference between the TCO value of the old vehicle and the new vehicle chosen (often smaller and/or less polluting).
