2011-04-13 | OFISD/MFB/FINA/CIR/DOC/24/11/2014The Central Bank of Nigeria (CBN) has mandated all Microfinance Banks (MFBs) to submit their monthly returns electronically via the FinA system. This change began with January 2011 returns and will be the only accepted method starting from June 2011. MFBs need to download their specific codes, rename their Master Files using the provided naming convention, and send electronic submissions by e-mail address: mfbreturns@cbn.gov.ng. Institutional e-mail addresses must also be registered with the CBN. Failure to comply may result in sanctions.
