Volume 11 explains investment banking in a broad sense, including its European and international dimensions. In addition to overviews of various areas including, for example, emissions trading it focuses primarily on commentaries on the following individual laws: WpHG [German Securities Trading Act] (now including the MM-VO and EMIR [Market Abuse Directive and European Market Infrastructure Regulation]), BörsG [Stock Exchange Act] WpProspG [Securities Prospectus Act], WpÜG [Security and Takeover Act], DepotG [Security Deposit Act]. The commentary and some presentations of individual laws are structured according to the parts that primarily affect bank organization, relationships with individual customers, or markets in general.
