Deutsche Boerse and SIX Swiss Exchange have announced that they are buying out Dow Jones’s one-third stake in Stoxx for a consideration of €206.1 million.

Following the transaction’s completion, which is due to take place early next year, Deutsche Boerse will have a controlling stake in Stoxx of 50% plus one share and will fully consolidate it for accounting purposes.

In addition, SIX and Deutsche Boerse will set up a new entity to perform index calculations, in which SIX will own 50% plus one share.

According to a Stoxx press release, the transaction will allow both Deutsche Boerse and SIX to significantly expand their positions in the international index business, complementing their established DAX and SMI index families.

It’s unclear how the ownership change and the sale by Dow Jones of its share in Stoxx will affect co-branded indices such as the DJ Euro Stoxx 50 index, the leading pan-European equity benchmark.

Stoxx was set up as a joint venture between Deutsche Boerse, Dow Jones and SIX Swiss Exchange in 1998 in anticipation of the introduction of the euro and the creation of the eurozone. Stoxx is Europe's leading index provider in the ETF market and Europe's number one (world number two) provider in the derivatives market, according to the company’s website.
