An official of KPMG, an audit firm, has revealed that the inefficiency of the Nigerian National Petroleum Company (NNPC) in the payment of demurrage on imported fuel at the ports has cost the country $65 million.

The official of the audit firm, Mr Dimeji Salaudin disclosed this when he appeared before the Senate Committee investigating the management of fuel subsidy in the country.

Mr Salaudin also told the committee that the Petroleum Product Pricing Regulatory Agency (PPPRA) overpaid oil marketers a whopping N25 billion in subsidy.

The Senate committee had summoned KPMG on Thursday over its failure to tender vital documents relating to the fuel subsidy scheme.

Not wanting to incur the wrath of lawmakers, two officials of audit firm KPMG appeared before the senate committee investigating the management of the fuel subsidy scheme.

The Minister of Finance had commissioned the international auditing firm in 2010 to review the subsidy regime from January 2007 to June 2010.

Giving details of the report, the KPMG representative said they discovered from their investigations that documents from the PPPRA to pay oil marketers were doctored.

The KPMG official also faulted the governance framework of PPPRA describing it as weak.

The committee directed the Minister of Finance to appear before it on Tuesday 5th June and also subpoenaed the CEOs of Oando PLC and Folawiyo Petroleum Company Limited to appear before it also on Tuesday.
