Governments in resource-rich African countries must effectively negotiate the terms of operational contracts with mining companies and their affiliates if they are to avoid revenue losses that reduce their capacity to finance development, the African Civil Society Circle has said.

The Circle is a coalition of nine civil society groups from Southern Africa whose goal is to strengthen Sub-Saharan voices in global, continental, regional and national development debates and promotion of good governance.

The report of a joint study by the African Development Bank and Global Financial Integrity, which traced the bulk of illicit financial flows in Africa to the natural resource sector, said the problem was as a result of flawed contract negotiations and transfer pricing.

The problem, the report said, was as a result of the absence of good governance structures that enable citizens to monitor the available amount and use of revenues.

The report said the difference in information between African governments and investors in the mining sector often resulted in tax avoidance through the underreporting of the quantity, quality and composition of minerals.

“Weak tax administrations coupled with multinational tax-avoidance schemes, engagement of multinational corporations in transfer pricing and other cross-border, intragroup transactions, negotiation of tax holidays and incentives and use of offshore investment accounts constitute about 60 per cent of illicit financial flows globally,” the report said.

Such aggressive transfer pricing schemes, involving the inflation of profits in low-tax jurisdictions and lower profits in high-tax jurisdictions, the report noted, was a problem affecting both developed and developing countries.

The report noted that despite attempts to implement the “arms -length principle” in regulating trade between related parties and affiliates, African governments must ensure that they are not short-changed due to ineffective monitoring of multinational corporations.

Since the presentation of the 2015 report of the High Level Panel on Illicit Financial Flows from Africa chaired by the former South African President, Thabo Mbeki, there has been greater awareness across Africa about the scale and impact of illicit financial flows on Africa.

Sub-Saharan African countries still mobilise less than 17 per cent of their gross domestic product in tax revenues due to money earned either illegally, transferred illegally or utilized illegally.

These financial leakages, the report noted, amounted to about $528.9billion (about N105.3trillion)) over the decade ending 2012, compared to $348.2billion (about N62.3 trillion) in official development assistance and $284billion (about N56.5trillion) in net inward foreign direct investment.
