According to Automotive News, the strategy is quite simple to understand. FCA is holding off until the first quarter of 2016 to divvy up the remaining Ferrari stock to shareholders. By doing so, the automaker gets to claim 80 percent of the Prancing Horse's profits for its 2015 financial numbers. While FCA is already showing strong results through Q1 2015, being able to add extra cash on the balance sheet is always a plus.
FCA hasn't set a specific date for the IPO, but Ferrari stock was announced to be traded in the US and possibly on a European exchange, as well. According to Automotive News, FCA currently owns 90 percent of the company, and Piero Ferrari has the remaining 10 percent, which he isn't selling.
