A listing on the stock exchange is contingent on certain legal requirements. These requirements serve to give investors a solid basis for reaching decisions. Therefore, the admission requirements for an exchange listing and the ongoing obligations imposed on listed companies focus mainly on the issues of minimum size and period of existence of the company, minimum volume of free float, and matters relating to information to be made available to investors in company disclosures in the form of, for example, financial statements and ad-hoc releases.
The overall market of the Vienna Stock Exchange is divided into different segments with differentiated issuer obligations. On account of the strict standards applicable to the regulated markets of the European Union, a considerable number of institutional investors invest exclusively in stocks listed on such markets for risk considerations or due to investment policies.
