The report, presented to the Senate on Thursday and reviewed by Reuters, was almost immediately sent back for further work because it did not capture possible infractions by all stakeholders, two people familiar with the matter said.
The upper house agreed in September to investigate whether Africa’s biggest telecoms firm unlawfully repatriated $13.92 billion from Nigeria – its most lucrative market which generates a third of its revenue – between 2006 and 2016.
MTN has denied any wrongdoing, but could not immediately be reached for comment.
The crux of the allegation is that MTN did not obtain certificates declaring it had invested foreign currency in Nigeria within a 24-hour deadline stipulated in a 1995 law, making the repatriation of returns on the investments illegal.
The Senate formed a committee to investigate the allegations against the South African company, the Central Bank of Nigeria (CBN) and commercial lenders such as Nigeria’s Stanbic IBTC Bank PLC.
The committee’s report did not recommend any punitive measures against MTN.
Instead, the report rebuked Nigeria’s central bank for its failure to monitor fund transfers to and from the country, calling its oversight of banks “inadequate.”
The report recommended that the Senate “condemned the Central Bank of Nigeria for failing in its duty” to address problems with monitoring foreign exchange transfers.
