In order to provide predictability to Member States under migratory pressure and to contributing Member States, the Report and the Decision should be accompanied by a Commission proposal identifying concrete annual solidarity measures, including relocations, financial contributions and, where applicable, alternative solidarity measures, and their numerical scale likely to be needed for the upcoming year at Union level, recognising that the various types of solidarity are of equal value. The types and numerical scale of the measures identified in the Commission proposal should as a minimum correspond to annual minimum thresholds for relocation and financial contributions. Those thresholds should be set out in this Regulation to ensure the predictable planning by contributing Member States and to provide minimum guarantees for the benefitting Member States. Where it is considered necessary, the Commission could identify in its proposal higher annual numbers for relocation or financial contributions. In order to preserve the equal value of solidarity measures, the ratio set out between the annual numbers identified in this Regulation should be maintained. In the same vein, when identifying the annual numbers, the Commission proposal should take into account exceptional situations where there would be no projected need for solidarity for the coming year.
