Total debt remained stable in 2021.In 2021, the loans guaranteed by the French State taken out in May 2020 with initial maturity in May 2021 have been extended until the third quarter of 2022. The amendments provide for reimbursements to be made over four years, beginning in July 2022 for the loan from Crédit Agricole and in September 2022 for the loans from Bpifrance and Société Générale.

The €9.9 million increase in 2020 is primarily attributable to the three loans taken out from a syndicate of French banks, in the form of the loans guaranteed by the French State for a total amount of €10.0 million. These loans have been taken out in May 2020 and mature in May 2021. In accordance with the guarantees put in place by the State in the context of the COVID-19 health crisis, the Company had the option to extend the maturity date for up to an additional four years.

To a lesser extent, this line item also includes the loan taken out from Société Générale in 2015 for a residual amount of €13 thousand.

At December 31, 2019, after repayment of borrowings due in 2019 in a total amount of €0.1 million, the debt relating to bank loans amounted to €0.1 million; and lease liabilities amounting to €37 thousand at December 31, 2019.
