Article 6 — Alternative, combined and cumulative funding

1. The Programme shall be implemented in synergy with other Union programmes. An action that has received a contribution from another Union programme may also receive a contribution under the Programme provided that those contributions do not cover the same costs. The rules of the relevant Union programme shall apply to the corresponding contribution, or a single set of rules of any of the contributing Union programmes may be applied to all contributions and a single legal commitment may be concluded. The cumulative support from the Union budget shall not exceed the total eligible costs of the action and may be calculated on a pro-rata basis in accordance with the documents setting out the conditions for support. 2. In order to be awarded a Seal of Excellence under the Programme, actions shall meet all of the following conditions: (a) have been assessed in a call for proposals under the Programme; (b) comply with the minimum quality requirements of that call for proposals; (c) not be financed under that call for proposals due to budgetary constraints. 3. In accordance with the relevant provisions of Regulation (EU) 2021/1060, the European Regional Development Fund (ERDF) or the European Social Fund Plus (ESF+) may support proposals submitted further to a call for proposals under the Programme which were awarded a Seal of Excellence.
