Key legal question
How should the contractual variable salary be interpreted and calculated for 2001 and 2002?
Extracted holding
The second addendum replaced the earlier metric with five objectives assessed on a 100-point scale; variable pay accrued only above 70 points and was payable pro rata temporis.
Extracted reasoning
The contractual text and appended table showed that the parties chose the qualitative-objectives method and that the bonus was reduced proportionally to the shorter employment period.
