Kassel, Germany — K+S Group is internally mulling the possibility of a partial initial public offering (IPO) for its U.S. Salt division, Morton Salt, according to a report in the Frankfurter Allgemeine Zeitung. Reasons for the move were reported to be creation of a “poison pill” to make an acquisition of K+S more difficult, as well as a means to make the value of the company’s Salt segment more visible.
