JOHANNESBURG--December 5, 2012--Written by Richard Finlayson, Senior International Editor for Industrial; Info Resources (Sugar Land, Texas)--South African companies are sitting on a potential investment hoard of about $63 billion and are enthusiastically looking into opportunities on the African continent, rather than making direct investments into domestic projects, says a Mergermarket report that was produced in collaboration with Nedbank and law firm Edward Nathan Sonnenbergs. However, the report says, South Africa has been the target for investors in 50% of the top 10 African merger and acquisition deals and is expected to be the leading sub-Saharan country for cross-border deals in 2013.
