Provisions for retirement benefit obligations

Note 15. Provisions for retirement benefit obligations

Retirement benefit obligations are determined based on the rights set forth in the national collective bargaining agreement for the French pharmaceutical industry (IDCC 176/Brochure 3104) and in accordance with IAS 19 — Employee Benefits. These rights depend on the employee’s final salary and seniority within the Company at his/her retirement date.

Principal actuarial assumptions

The following assumptions were used to measure the obligation:

	As of December 31,
Parameters	2022		2023		2024
Retirement age	65	years	65	years	65	years
Payroll taxes	41.41	%	41.41	%	41.41	%
Salary growth rate	2.00	%	2.00	%	2.00	%
Discount rate	3.70	%	3.20	%	3.40	%
Mortality table	TGH/TGF 05		TGH/TGF 05		TGH/TGF 05

The discount rate corresponds to the rates of Eurozone AA-rated corporate bonds with maturities of over ten years.

Net provision

The provision recorded in respect of defined benefit schemes at the end of each reporting period is shown in the table below:

	As of December 31,
In thousands of euros	2022	2023	2024
Retirement benefit obligations	1,234	1,559	1,762
Total obligation	1,234	1,559	1,762

Given the absence of plan assets at December 31, 2024, 2023 and 2022 the total amount of the provision corresponds to the estimated obligation at those dates.
