MTN Group Limited (JSE:MTN) says it may put off plans to list its Nigerian operation until 2018 as Africa's largest wireless carrier works to resolve a regulatory dispute and awaits an economic recovery in the continent's most populous country. MTN agreed to list the unit in Nigeria as part of the settlement of a NGN 330 billion fine imposed on it by the government for missing a deadline to disconnect unregistered subscribers. It said in July 2016 that the listing would take place in 2017, subject to market conditions. "We've always intended to list, we have reaffirmed that with the government. Clearly, we can only list when the conditions are conducive," said Phuthuma Nhleko, Chairman and acting Chief Executive Officer of MTN. In July 2016, MTN appointed units of Citigroup Inc. (NYSE:C) and Standard Bank Group Limited (JSE:SBK) to advise on the Nigeria listing.
