NEWS Bombardier breakup may be best prescription for a revival

A breakup may be Bombardier Inc.’s best option for gaining liftoff. Shares of the US$3.5 billion maker of planes and high-speed trains have slumped almost 40 percent in a year, while rivals such as Boeing Co. and Airbus Group NV rallied. Delays and cost overruns and delays on the new CSeries jetliner dragged Bombardier to its first annual loss in almost a decade last year. The company’s debt is more than twice its market value.
