"I'd like to get everything done within 2015, IPO and spin-off. If we cannot make each one this year, it’s purely for regulatory reasons," Marchionne told analysts during a conference call to present the company's full-year results.

Marchionne said in October he would spin off Ferrari from the group, sell a 10 percent stake via a public offering and distribute the rest of FCA's stake to its shareholders.
