According to a release issued today Renault, Nissan and GM have agreed to terminate discussions regarding a proposed alliance among the three companies. Here is an extract from the release"

"The parties mutually recognized that significant aggregate synergies might
result from the alliance. However the parties did not agree on either the total
amount of aggregate synergies or the distribution of those benefits. Based on
its conclusions, GM had proposed that Renault-Nissan provide compensation as
part of a potential alliance and for potentially precluding GM from entering
other alliance opportunities if Renault-Nissan had made a significant investment
in GM.

Renault and Nissan consider that the principle of compensation is
contrary to the spirit of any successful alliance."
