2. Cautionary Statements • Embedded Value is the result of cash-flow projections with underlyingassumptions and expectations. The values in this presentation are calculated on a deterministic basis. • Many assumptions, such as the general economic conditions, performance of financial markets, taxes, changes in laws, frequency and severity of insured loss events, mortality and morbidity levels and trends, and others, are beyond the control of KBC. A modification of assumption can result in a significantly different Embedded Value. Deviations from assumed experience are normal and are to be expected. Even without any change in the parameters, actual results will vary from those projected due to normal random fluctuations. • Embedded Value cannot be considered as an absolute value. This value, together with a sensitivity analysis, enables the recipient to obtain an idea of the magnitude of the expected value created by the insurance activities. • Under no circumstances should the inclusion of the projections (including the relevant underlying assumptions and expectations) be regarded as a representation, warranty or prediction that the business will achieve or is likely to achieve any particular results.

21. Review Lane Clark & Peacock Belgium reviewed the methodology and assumptions used by KBC Insurance in the determination of the Embedded Value at 31/12/2005, the Value of 2005 New Business and the analysis of the change in the value of in-force business for the Life Insurance activities of KBC Insurance. It is the view of Lane Clark & Peacock Belgium, based on the data made available, that the assumptions used are reasonable and that the methodology used by KBC Insurance is in line with basic principles described in appropriate literature. Our assignment included a review of the calculations.This review was not a detailed verification of the correctness of all calculations. This review was a limited high-level reasonableness checks on the results and included a detailed review on a limited random sample of contracts of the insurance portfolio of KBC Insurance. No material issues have been discovered. Therefore, based on our work and our validation report on the work carried out by KBC Insurance, we consider the embedded value, the value of new business and the analysis of the change in the value of in-force for the life business to be reasonable and suitable for inclusion as supplementary information to the Group’s consolidated accounts.
