Note annual salary: The basic salary is the expected annual salary subject to OASI contributions. It is determined on the basis of the last known OASI salary, taking into account any changes that have already taken effect or which have been agreed for the current year. It does not include salary components paid only occasionally. The latter include, in particular, gifts rewarding years of service and similar, special compensation paid irregularly and/or that is not contractually guaranteed. For persons who are employed for less than 12 months in a calendar year, the annual salary is considered to be the salary that the insured person would achieve if employed for the whole year.
