South African companies with operations in Nigeria are being tight-lipped about the impact on their investments of terror group Boko Haram's attacks in the region.
They seem reluctant to do anything that may unsettle the Abuja government before next month's election.
About 200 South African companies, some listed on the JSE, have operations in the continent's most populous country, in which they have invested billions.
Experts say no company with ambitions to expand in Africa can exclude Nigeria.
South African companies with operations in Nigeria include Shoprite, Standard Bank, Tiger Brands and Sanlam.
Dianna Games, executive director of the South Africa-Nigeria Chamber of Commerce, said Nigeria's economy, the largest in Africa, was too big to ignore.
But is it losing its status as the gateway to West Africa?
Boko Haram has hit foreign direct investment hard since its attacks began in 2010. Investment fell from $8.9- billion in 2011 to $5.6-billion in 2013.
Some companies, such as Stanlib, are setting up headquarters in Ghana, intending to operate their investments in Nigeria from the nearby state.
On Friday, IVM Intersurer, which holds a significant investment in Hollard Insurance, said it had extended its reach into West Africa by acquiring a majority stake in Metropolitan Insurance Company, in Ghana.
Ghana, just a short flight from Nigeria, was a much easier living and operating environment. But Games said that Nigeria had more air links than Ghana, and "really is the hub of West Africa".
