Thomas Eichelmann unexpectedly quit the CFO post at Deutsche Börse, the stock exchange operator, after only two years. The company explained his departure as due to “partial differences concerning individual business aspects.” CEO Reto Francioni will take over Eichelmann’s financial duties until a successor is found. The outgoing CFO was credited with a successful cost-cutting drive that led to record-setting annual net income of more than €1 billion last year.

Beleaguered British sports retailer JJB announced the resignation of finance director David Madeley and detailed the termination of chief executive Chris Ronnie in January as related to reasons of “gross misconduct.” Ronnie’s large stake in the company was seized by administrators of collapsed Icelandic bank Kaupthing.

Executive director Peter Williams will take on finance duties at JJB until a replacement for Madeley is found.
