A report from US-based advocacy group Global Financial Integrity (GFI) has highlighted how much money is siphoned out of African countries due to the practice of over or understating invoices. In its report, Hiding in Plain Sight, GFI analysed data on bilateral trade flows for 2002–11 from the United Nations’ Comtrade database to estimate misinvoicing for Ghana, Kenya, Mozambique, Tanzania, and Uganda. It found that Tanzania experienced the greatest annual average gross illicit flows with $1.87bn. Kenya is second with $1.51bn/yr, and Ghana’s figure of $1.44bn is also significant. Uganda had illicit outflows of $884m/yr, and Mozambique’s figure is $585m.
