The following six [[European Union|EU]] member states, representing 95 million people, committed themselves in their respective [[Treaty of Accession]] to adopt the euro. However they do not have a deadline to do so and can delay the process by deliberately not complying with the convergence criteria (such as by not meeting the convergence criteria to join ERM II). Bulgaria and Romania are actively working to adopt the euro, while the four remaining states do not have a migration plan in progress.
