MTN Group’s Nigerian unit plans to raise about 200-billion naira ($555-million) this year from a variety of sources including bank loans and bonds to expand operations in its biggest market. The funds will enable Africa’s largest wireless carrier to finance capital expenditure to increase the reach and efficiency of its network in Nigeria, Chief Financial Officer Adekunle Awobodu said by phone from Lagos. MTN has also started the process of listing its shares on the Nigerian Stock Exchange.
