(12)As the assessment of appropriateness has, in principle, to be conducted in all cases where insurance-based investment products are sold without advice, insurance intermediaries and insurance undertakings should perform such an assessment in all situations where, in conformity with the applicable rules of national law, the customer requires a sale without advice and where the conditions of Article 30(3) of Directive (EU) 2016/97 are not met. In cases where a suitability assessment cannot be performed because the necessary information about the customer's financial situation and investment objectives cannot be obtained, the customer might agree, in conformity with the applicable rules of national law, to proceed with concluding the contract as a sale without advice. However, in order to ensure that the customer has the necessary knowledge and experience in order to understand the risks involved, an assessment of appropriateness should be required in such situations, unless the conditions of Article 30(3) of Directive (EU) 2016/97 are met.
