3. Japanese Automakers Honda, Nissan Call Off Merger

Japanese automaker Honda Motor's ( HMC ) U.S.-listed shares are roughly 2% higher in premarket trading after merger plans with its domestic rival Nissan Motor were called off. The companies, along with Nissan-controlled Mitsubishi Motors, said they ended plans for a "tripartite collaboration" but didn’t provide a reason for ending the deal. The Financial Times had reported the deal was in jeopardy after Honda unexpectedly proposed a new structure that would have made Nissan a fully owned subsidiary.
