Article 140(1) of the Treaty on the Functioning of the European Union (hereafter TFEU) requires the Commission and the European Central Bank (ECB) to report to the Council, at least once every two years, or at the request of a Member State with a derogation, on the progress made by the Member States in fulfilling their obligations regarding the achievement of economic and monetary union. The latest Commission and ECB Convergence Reports were adopted in June 2014. The 2016 Convergence Report covers the following seven Member States with a derogation: Bulgaria, the Czech Republic, Croatia, Hungary, Poland, Romania and Sweden. A more detailed assessment of the state of convergence in those Member States is provided in a Technical Annex to this Report.
