(Vienna) The Vienna Stock Exchange set new free float factors in the context of the quarterly review of the calculation factors of the Austrian stock indices ATX and ATX Prime this evening. For the real estate company BUWOG and for the catering company DO&CO the free float factors increase from 0.6 to 0.7 respectively due to the notifications on the sale of shareholdings. The free float factor represents the portion of a company's shares that are in the hands of a multitude of public investors and tradable on the stock exchange. A higher free float indicates a better tradability of a share on the stock exchange and results in a higher weighting of the company in the index. The changes will become effective on 21 December 2015.

The inclusion or exclusion of stocks from the ATX is reviewed twice a year (March and September).
