This decree and ministerial order require the discount rate to comply with two regulatory limits from 1 July 2020. It must be lower than:
The maximum discount rate under the new ministerial order effective from 1 July 2020, calculated by reference to the UFR, is 2.7% (real rate of 2.66% rounded up to 2.7%) at 31 December 2020.
The real discount rate used in the financial statements at 31 December 2020, in application of the methodologies presented above, is 2.1%.
The maximum discount rate in nominal value, based on the regulation applicable before the ministerial order of 1 July 2020 and calculated by reference to TEC 30 rates, was 3.8% (3.75% rounded up to 3.8%) at 31 December 2019. The nominal discount rate used in the financial statements at 31 December 2019 was 3.7%.
The decree of 1 July 2020 also introduced the following additional changes:
Sensitivity to assumptions concerning costs, inflation rate, long-term discount rate, and disbursement schedules can be estimated through comparison of the gross amount estimated under year-end economic conditions with the present value of the amount.
