Mercedes has issued an official statement following a meeting to resolve the situation that arose in Belgium last week.
"Toto Wolff, Paddy Lowe, Nico Rosberg and Lewis Hamilton met today in the boardroom in Brackley to discuss the events of the Belgian Grand Prix.
During this meeting, Nico acknowledged his responsibility for the contact that occurred on lap two of the Belgian Grand Prix and apologised for this error of judgement.
Suitable disciplinary measures have been taken for the incident.
Mercedes-Benz remains committed to hard, fair racing because this is the right way to win world championships. It is good for the team, for the fans and for Formula One.
Lewis and Nico understand and accept the team's number one rule: there must be no contact between the team's cars on track.
It has been made clear that another such incident will not be tolerated. But Nico and Lewis are our drivers and we believe in them.
They remain free to race for the 2014 FIA Formula One World Championship."
