The Asylum and Migration Management Regulation[1] foresees a mandatory but flexible solidarity mechanism, whereby each Member State has full discretion to choose between the available forms of solidarity, namely relocation, financial contributions and alternative measures (in-kind support).

A reference key, based on the size of the population (50% weighting ) and of the gross domestic product of the Member States (50% weighting ), should be applied in accordance with the mandatory fair share principle for the operation of the solidarity mechanism enabling the determination of the overall contribution of each Member State.

The Asylum and Migration Management Regulation also foresees possible deduction of solidarity contributions for Member States facing migratory pressure or a significant migratory situation.

The Asylum and Migration Management Regulation also requires that e ach year, by 15 October, the Commission adopts an implementing decision determining whether a particular Member State is under migratory pressure, at risk of migratory pressure during the upcoming year, or facing a significant migratory situation.

In doing so, the Commission will take into account qualitative and quantitative indicators, in accordance with Articles 9 and 10 of the regulation, including the number of beneficiaries of temporary protection in a given Member State. M ilitary assistance provided to Ukraine is not among the indicators set by the regulation.
