The fine that McLaren will have to pay as a result of the World Motor Sport Council's judgement in the spying affair will be 'in excess of $50 million (USD)', the FIA has confirmed.
The team were fined $100 million USD and lost all their constructors' championship points when found guilty of having benefited from the receipt of confidential Ferrari information.
But that total included the revenue that would have been earned in prize money for their eventual finishing position in the 2007 constructors' championship.
With the loss of constructors' points from the Hungarian Grand Prix taken into account, McLaren would have come second in the 2007 standings behind Ferrari at the end of the season.
With the final positions settled by the results of last weekend's Brazilian Grand Prix, the FIA has now been able to calculate how much money McLaren will have to pay.
"Following the judgement of the World Motor Sport Council on 13 September, a sum in excess of $50 million will be paid in December to the FIA," said an FIA statement.
The governing body also confirmed that the money would be distributed amongst national motorsport authorities and used to improve safety, and that Mercedes and Ferrari would be given a say in how it was spent.
"This will be used to establish the FIA Development Fund, which will assist the work of National Sporting Authorities (ASNs) in promoting the development of safer motor sport worldwide, especially in countries where the motor sport infrastructure is in need of support," said the statement.
"Representatives from Mercedes and Ferrari will be invited to join the Fund's board."
