Simuleringen tillåter att studera vilken som helst variabel inom företaget, men de viktigaste variablerna är företagets utbetalda dividender som mäter företagets förmåga att skapa värde för aktieägare och företagets tillväxttakt som mäter företagets hälsa.
När man jämför företagets förmåga att skapa värde eller tillväxt visar resultaten alltid samma ordning: Företaget får mest problem med valutor när det inte skyddar sig alls.
Situationen är bättre för företaget som använder optioner, men för företaget som använder forwardkontrakt går det alltid bäst.
Resultaten är robusta och visar samma konklusioner oberoende av specifikationer i simuleringen eller val av de variabler som man följer.
En intressant detalj är att när man följer företagets behov av extern finansiering i det fall då företaget inte skyddar sig alls, så har företaget högst behov av kredit precis när tillången till kredit är sämst på den finansiella marknaden. Det betyder att problemen som företaget redan har med valutorna blir ännu värre när företaget måste konfrontera den omgivande ekonomin.
På grund av intern funktionalitet måste företag skydda sig mot valutarisker. Genom att använda skydd kan företag öka på sitt värde oberoende av hurdana preferenser aktieägare har. Med fokus på den interna funktionaliteten visar avhandlingen även att icke-linjära finansiella konrakt inte är optimala för valutarisken. Företag kan maximera värdet endast genom att använda linjära kontrakt.
