At the Africa CEO Forum in Abidjan, in June, the irrepressible chairman of BUA Group, Abdul Samad Rabiu, is bubbling. He has just signed a $500m credit facility led by the International Finance Corporation (IFC). Rabiu moves between interviews, photos with business and government leaders and congratulating the team that put the substantial deal together. In these days of 1,000 naira to a dollar, $500m is the equivalent of 500 billion naira.
