Since it is a matter of comparing financial flows for France Télécom spread over a period of time, i.e. the payment of the exceptional contribution in 1997 and the reduced annual charges resulting from the 1996 Law since then, discounting to present value is necessary.
Selleks et võrrelda pikema perioodi jooksul France Télécomi rahavooge, st erakorralise sissemakse tasumine 1997. aastal ja 1996. aasta seadusest tulenevad väiksemad iga-aastased maksed, on vajalik need summad ajakohastada.
