Bonus-malus arrangement

Definición

A bonus-malus arrangement links a supplier's fee to measured performance: exceeding agreed targets earns a bonus, while falling short triggers a malus (deduction). Used in service and outsourcing contracts, it aligns supplier behaviour with the client's goals as a commercial incentive. The arrangement rests on contractual freedom rather than statute, though a malus that operates as a penalty may engage the rules on penalty clauses.

Ejemplo

A logistics provider earns a 3% bonus for beating delivery targets and forfeits 3% if punctuality drops below the agreed level.

Por qué es un riesgo para la empresa

Bonus-malus arrangements only work if the performance metrics are objectively measurable and both parties trust the measurement method. Disputes over data quality, measurement periods or force-majeure events can cause the incentive mechanism to break down and trigger unexpected deductions. A poorly designed arrangement can also incentivise gaming -- hitting measured KPIs while neglecting unmeasured quality.

Cómo gestionarlo

• Define each KPI precisely: the data source, measurement method, calculation period and dispute resolution process for contested readings.
• Agree on a baseline assessment before the arrangement takes effect so targets reflect realistic starting performance rather than aspirational levels.
• Include force-majeure and excused-performance carve-outs so a malus does not apply when the underperformance was caused by the client or by circumstances outside the supplier's control.
• Cap the total malus exposure and link it to the penalty-clause mitigation rule so excessive deductions can be moderated by a court if needed.
• Review KPI targets at regular intervals and adjust them if the baseline has shifted materially, especially in long-term contracts.
