(Vienna) The construction company PORR AG will be added into the leading Austrian index ATX on 26 June 2018. Austria's oldest listed company will be included in the ATX for the first time in its history. The extraordinary inclusion follows the decision to remove BUWOG AG from the ATX and other indices of the Vienna Stock Exchange. In this case, the rules adopted by the Index Committee provide for the admission of a new candidate. The reason for the exclusion of BUWOG AG is that Vonovia SE holds more than 90% of the BUWOG shares after expiry of the extended acceptance period of the takeover bid and announced a squeeze-out procedure. The next scheduled review of the ATX composition will take place on 4 September 2018.
According to "The Rules for the Austrian Indices of the Vienna Stock Exchange", the inclusion or exclusion of stocks from the Austrian indices is reviewed twice a year (March and September). Decisions on new additions to the index are based on average daily trading volumes and the free float capitalization of companies. The Vienna Stock Exchange reviews the calculation parameters (number of shares, free float factors, representation factors) of the index on a quarterly basis. Once a month, the "ATX watchlist" is published. Representatives of institutional investors, financial institutions that issue financial products on the indices, trading members of the Vienna Stock Exchange, academics advisors and the Vienna Stock Exchange contribute their know-how to the Index Committee, which approves the index rules.
