It is the value the acceleration coefficient will take when applying the associations. This coefficient is linked with the UD modes management (Declining balance) and DB (Belgian digressive) and can only be entered for these depreciation methods. When this factor is applied to the DB (Belgian declining) mode, it must be included between 1 and 2 and contain up to 2 decimals (examples: value 2 corresponds to 200 %; the value 1.5 corresponds to 150 %).
