TMTPOST -- Renault said Tuesday it expects to post an extraordinary loss of approximately €9.5 billion ($11.2 billion) in the first half of the year due to a shift in how it accounts for its stake in Nissan Motor. The accounting change comes as the French automaker unwinds parts of its two-decade alliance with Nissan, gradually reducing its holdings in the Japanese company, which continues to struggle with falling sales and mounting pressure to improve liquidity.
