The Ghosn effect? Nissan and Renault set to unveil first post-crisis results

TOKYO/PARIS - What kind of financial blow has the widening scandal surrounding Carlos Ghosn delivered to Nissan Motor Co. and Renault SA? Investors are about to get a glimpse when closely watched earnings releases come out this week. The alliance partners have spent the last two months coping with a major reputational hit from Ghosn's arrest, indictments by Tokyo prosecutors over alleged financial improprieties and an unflattering spotlight on both companies' corporate governance controls. Taken together, these negatives could leave the alliance partners falling behind competitors such as Volkswagen AG and Toyota Motor Corp. in the race to adapt to the changing terrain. The risks may be greater for Nissan since the lion's share of allegations against Ghosn reflect his tenure there, and its business challenges are tougher than Renault's.
