Carlos Ghosn to step down as Nissan boss

My students and I  in my class today found out why Carlos Ghosn, one of the best-known leaders in the automotive industry, has announced that he will step down as Nissan Motor's president and CEO, effective April 1. The hugely successful Mr Ghosn will remain with the company as chairman to oversee a wider group of carmakers that, in addition to Nissan, includes France's Renault and Japan's Mitsubishi Motors.
