Définition
The growth overhang of a variable for a year N corresponds to the growth rate of the variable between year N-1 and year N that would be obtained if the variable remained until the end of year N at the level during the last known quarter.
For example, when the last known quarter for a year N is the third quarter, the variable's growth overhang for year N is equal to the growth rate between N-1 and N that would be obtained if the variable remained at the same level in the fourth quarter as in the third quarter.
