OCI and U.S. fertilizers player CF Holdings have called off a USD 8 bn merger that would have created one of the world’s largest fertilizers plays “the latest multibillion-dollar transaction to run afoul of changes to U.S. tax rules designed to restrict so-called inversion deals,” the Wall Street Journal (paywall) reports, writing, “The companies said they were unable to come up with a structure for a deal to combine CF Industries with some of OCI’s operations that would create value for shareholders, citing a tougher regulatory and commercial environment.” OCI will receive breakup fees of USD 150 mn from CF Holdings. Reuters has more on the news. The companies had announced in December 2015 that they were changing the proposed tax residence of the merged entity in what analysts saw as a bid to sidestep the tax inversion issue.
