The European Commission adopted new Guidelines for regional aid for the period 2014–2020. The new legal framework will have significant impact on the possibility of public support for investments of public and private undertakings in the European Union. Major policy changes include the limitation of the possibility for large undertakings to benefit from regional aid and a more restrictive method of calculating the acceptable aid amount. Public authorities granting regional aid as well as companies benefitting from regional aid should be aware that the new Guidelines will enter into force on 1 July 2014, but that all existing aid schemes as well as the current regional maps will already expire on 31 December 2013.
