The United Bank for Africa (UBA) said on Tuesday it had made a provision on loans made to 9mobile, the mobile operator formerly known as Etisalat Nigeria.
The lender did not give details of the provision but said it had a N38 billion ($125 million) exposure to 9mobile.
UBA said the exposure was secured, and part of a syndicated loan with a group of 12 other banks extended to 9mobile four years ago.
