The present paper deals with the amendments to the Slovenian Companies Act especially in regard to company reorganizations by the implementation of Directive 2009/109/EC in 2012. This Directive envisaged simplification of merger and division procedures of companies by: a) simplifying information requirements for notification to shareholders prior to an assembly which decides on the merger or division, especially in cases of the so-called group mergers and divisions; b) identifying unnecessary duplication of producing specific reports, if such reports are prepared under other provisions and c) liberalization of the conditions of Internet use and other devices for electronic communication. In addition, the authors deal with the procedures of merger by acquisition and merger by formation of a new company in Slovenian law.
