(81)The requirement that the internal model is widely used in and plays an important role in their system of governance set out in Article 120 of Directive 2009/138/EC should not lead insurance and reinsurance undertakings to rely blindly on the output of the internal model. The undertakings should not make decisions based on the output of the internal model without challenging the appropriateness of the model. They should be aware of the limitations of the internal model and take them into account in their decisions.
