È importante rispettare le leggi ABAC in ogni Paese in cui operiamo e aumentare la nostra consapevolezza e attenzione quando lavoriamo con Paesi o in Paesi in cui il rischio di corruzione e concussione può essere maggiore. Il limite tra legale e illegale nei pagamenti agevolanti è sottile, poiché è possibile che tali pagamenti vengano interpretati come tangenti. I pagamenti ai funzionari pubblici devono essere prontamente segnalati e adeguatamente registrati e devono includere lo scopo, l’importo e altri fattori rilevanti.
