The Commission prepared Progress Reports for the candidate countries Croatia, the former Yugoslav Republic of Macedonia, Iceland and Turkey as well as for the potential candidate countries Bosnia and Herzegovina and Serbia and for Kosovo (1). Following the two countries application and the Council's request, it also prepared two opinions on Albania and Montenegro. The European Commission adopted the Progress Reports and two Opinions on 9 November 2010. The purpose of this Occasional Paper is to facilitate the work of those scholars, researchers and analysts of the enlargement process, who are mainly interested in the economic aspects. As such, it represents only a part of the overall progress made by the candidate and potential candidate countries towards meeting the accession criteria. A proper full-fledged assessment of progress made under all examined aspects can be found in the 2010 Progress Reports and Opinions.
