Additionality is a principle of the European Union's cohesion policy aiming to ensure that the Structural Funds 1 complement but do not replace equivalent public expenditure of a Member State.
Article 15 of Council Regulation (EC) No 1083/2006 specifies that the Commission should verify additionality in the Convergence objective in cooperation with each concerned Member State by the end of 2016 and should publish the results of this exercise. Although, under the regulations, Croatia has an additional year for this verification process, the Croatian authorities decided to submit all documentation one year early.
This report therefore closes the verification of additionality for the 2007-2013 programming period, after the ex-ante and the mid-term verifications carried out in 2007 and 2011-2012 respectively.
