1. Where insurance and reinsurance undertakings make assumptions about rules relating to the valuation of assets and liabilities, technical provisions, own funds, solvency capital requirements, minimum capital requirements and investment rules, these assumptions shall be based on the expertise of persons with relevant knowledge, experience and understanding of the risks inherent in the insurance or reinsurance business.
2. Insurance and reinsurance undertakings shall, taking due account of the principle of proportionality, ensure that internal users of the relevant assumptions are informed about their relevant content, their degree of reliability and their limitations. For that purpose, service providers to whom functions or activities have been outsourced shall be considered to be internal users.
