For life insurance and capitalisation contracts where a unit of account is made up of units in a company mentioned in article L. 160-10 or by a société civile de placement immobilier and subject to articles L. 160-14 and L. 160-15, the adoption by such a company of the system for undertakings for collective real estate investment, under the conditions defined in this section, entails the substitution of this unit of account by the unit of account expressed in units of an undertaking for collective real estate investment resulting from the adoption of the new system. This substitution is made without application of the fifth paragraph of article L. 112-3. The same applies, where applicable, to adaptations to the provisions of the contracts, in particular those relating to any clause allocating sums distributed by the company referred to in article L. 160-10 to the insurance contract, to the extent strictly necessary as a result of the adoption by the said company of the system for open-ended real estate investment companies (sociétés de placement à prépondérance immobilière à capital variable). Such adaptations are subject to the prior authorisation of the authority referred to inarticle L. 612-1 of the Monetary and Financial Code , which has two months in which to give its opinion. The authority shall also verify, prior to the substitution and within the same timeframe, that the information document drawn up by the new company and referred to in article L. 214-53 of the Monetary and Financial Code maintains the management approach adopted by the said company with regard to the criteria for the destination and location of the real estate assets.
