INTRODUCTION
In a modern economy, there is distinction between the surplus economic units and the deficit economic units and inconsequence a separation of the savings investment mechanism. This has necessitated the existence of financial institution whose jobs include the transfer of funds from savers to investors. It is generally expected that developing countries, facing a scarcity of capital, will acquire external debt to supplement domestic saving (Malik et al, 2010; Aluko and Arowolo, 2010).
