In August 1990, Iraq invaded Kuwait, and the United Nations imposed sanctions against Iraq. Security Council resolution 661 of 1990 prohibited all nations from buying and selling Iraqi commodities, except for food and medicine. Security Council resolution 661 also prohibited all nations from exporting weapons or military equipment to Iraq and established a sanctions committee to monitor compliance and progress in implementing the sanctions. The members of the sanctions committee were members of the Security Council. Subsequent Security Council resolutions specifically prohibited nations from exporting to Iraq items that could be used to build chemical, biological, or nuclear weapons. In 1991, the Security Council offered to let Iraq sell oil under a U.N. program to meet its peoples’ basic needs. The Iraqi government rejected the offer, and over the next 5 years, the United Nations reported food shortages and a general deterioration in social services. In December 1996, the United Nations and Iraq agreed on the Oil for Food program, which permitted Iraq to sell up to $1 billion worth of oil every 90 days to pay for food, medicine, and humanitarian goods. Subsequent U.N. resolutions increased the amount of oil that could be sold and expanded the humanitarian goods that could be imported. In 1999, the Security Council removed all restrictions on the amount of oil Iraq could sell to purchase civilian goods. The United Nations and the Security Council monitored and screened contracts that the Iraqi government signed with commodity suppliers and oil purchasers, and Iraq’s oil revenue was placed in a U.N.-controlled escrow account. In May 2003, U.N. resolution 1483 requested the U.N. Secretary General to transfer the Oil for Food program to the CPA by November 2003. (Appendix II contains a detailed chronology of Oil for Food program and sanctions events.) The United Nations allocated 59 percent of the oil revenue for the 15 central and southern governorates, which were controlled by the central government; 13 percent for the 3 northern Kurdish governorates; 25 percent for a war reparations fund for victims of the Iraq invasion of Kuwait in 1990; and 3 percent for U.N. administrative costs, including the costs of weapons inspectors. From 1997 to 2002, the Oil for Food program was responsible for more than $67 billion of Iraq's oil revenue. Through a large portion of this revenue, the United Nations provided food, medicine, and services to 24 million people and helped the Iraqi government supply goods to 24 economic sectors. Despite concerns that sanctions may have worsened the humanitarian situation, the Oil for Food program appears to have helped the Iraqi people. According to the United Nations, the average daily food intake increased from around 1,275 calories per person per day in 1996 to about 2,229 calories at the end of 2001. Malnutrition rates for children under 5 fell by more than half. In February 2002, the United Nations reported that the Oil for Food program had considerable success in several sectors such as agriculture, food, health, and nutrition by arresting the decline in living conditions and improving the nutritional status of the average Iraqi citizen. From 1997 through 2002, we estimate that the former Iraqi regime acquired $10.1 billion in illegal revenues—$5.7 billion in oil smuggled out of Iraq and $4.4 billion in surcharges on oil sales and illicit charges from suppliers exporting goods to Iraq through the Oil for Food program. The United Nations, through OIP and the Security Council’s Iraq sanctions committee, was responsible for overseeing the Oil for Food program. However, the Security Council allowed the Iraqi government, as a sovereign entity, to negotiate contracts directly with purchasers of Iraqi oil and suppliers of commodities. This structure, in addition to the uncertain oversight roles of OIP and the sanctions committee, was an important factor in enabling Iraq to levy illegal surcharges and illicit commissions. U.N. external audit reports contained no findings of program fraud. Summaries of internal audit reports provided to GAO pointed to some operational concerns in procurement, coordination, monitoring, and oversight. We estimate that, from 1997 through 2002, the former Iraqi regime acquired $10.1 billion in illegal revenues—$5.7 billion through oil smuggled out of Iraq and $4.4 billion through surcharges against oil sales and illicit commissions from commodity suppliers. This estimate is higher than the $6.6 billion in illegal revenues we reported in May 2002. We updated our estimate to include (1) oil revenue and contract amounts for 2002, (2) updated letters of credit from prior years, and (3) newer estimates of illicit commissions from commodity suppliers. Appendix I describes our methodology for determining illegal revenues gained by the former Iraqi regime. Oil was smuggled out through several routes, according to U.S. government officials and oil industry experts. Oil entered Syria by pipeline, crossed the borders of Jordan and Turkey by truck, and was smuggled through the Persian Gulf by ship. Jordan maintained trade protocols with Iraq that allowed it to purchase heavily discounted oil in exchange for up to $300 million in Jordanian goods. Syria received up to 200,000 barrels of Iraqi oil a day in violation of the sanctions. Oil smuggling also occurred through Turkey and Iran. In addition to revenues from oil smuggling, the Iraqi government levied surcharges against oil purchasers and commissions against commodity suppliers participating in the Oil for Food program. According to some Security Council members, the surcharge was up to 50 cents per barrel of oil and the commission was 5 to 15 percent of the commodity contract. In our 2002 report, we estimated that the Iraqi regime received a 5-percent illicit commission on commodity contracts. However, a September 2003 Department of Defense review found that at least 48 percent of 759 Oil for Food contracts that it reviewed were potentially overpriced by an average of 21 percent. Food commodity contracts were the most consistently overpriced, with potential overpricing identified in 87 percent of the contracts by an average of 22 percent. The review also found that the use of middlemen companies potentially increased contract prices by 20 percent or more. Defense officials found 5 contracts that included “after- sales service charges” of between 10 and 20 percent. In addition, interviews by U.S. investigators with high-ranking Iraqi regime officials, including the former oil and finance ministers, confirmed that the former regime received a 10-percent commission from commodity suppliers. According to the former oil minister, the regime instituted a fixed 10-percent commission in early 2001 to address a prior “compliance” problem with junior officials. These junior officials had been reporting lower commissions than what they had negotiated with suppliers and pocketing the difference. Both OIP, as an office within the U.N. Secretariat, and the Security Council’s sanctions committee were responsible for overseeing the Oil for Food Program. However, the Iraqi government negotiated contracts directly with purchasers of Iraqi oil and suppliers of commodities. While OIP was to examine each contract for price and value, it is unclear how it performed this function. The sanctions committee was responsible for monitoring oil smuggling, screening contracts for items that could have military uses, and approving oil and commodity contracts. The sanctions committee responded to illegal surcharges on oil purchases, but it is unclear what actions it took to respond to commissions on commodity contracts. U.N. Security Council resolutions and procedures recognized the sovereignty of Iraq and gave the Iraqi government authority to negotiate contracts and decide on contractors. Security Council resolution 986 of 1995 authorized states to import petroleum products from Iraq, subject to the Iraqi government’s endorsement of transactions. Resolution 986 also stated that each export of goods would be at the request of the government of Iraq. Security Council procedures for implementing resolution 986 further stated that the Iraqi government or the United Nations Inter-Agency Humanitarian Program would contract directly with suppliers and conclude the appropriate contractual arrangements. Iraqi control over contract negotiations was an important factor in allowing Iraq to levy illegal surcharges and illicit commissions. When the United Nations first proposed the Oil for Food program in 1991, it recognized this vulnerability. At that time, the Secretary General proposed that the United Nations, an independent agent, or the government of Iraq be given the responsibility to negotiate contracts with oil purchasers and commodity suppliers. The Secretary General concluded that it would be highly unusual or impractical for the United Nations or an independent agent to trade Iraq’s oil or purchase commodities. He recommended that Iraq negotiate the contracts and select the contractors. However, he stated that the United Nations and Security Council would have to ensure that Iraq’s contracting did not circumvent the sanctions and was not fraudulent. The Security Council further proposed that U.N. agents review contracts and compliance at Iraq’s oil ministry, but Iraq refused these conditions. Iraqi government control over contracts applied to oil purchases, all commodities purchased for the 15 central and southern governorates, and food and medical supplies purchased in bulk by the central government for the three autonomous Kurdish governorates in the north. The rest of the program in the north was run by nine specialized U.N. agencies and included activities such as distributing food rations and constructing or rehabilitating schools, health clinics, power generation facilities, and houses. OIP administered the Oil for Food program from December 1996 to November 2003. Under Security Council resolution 986 of 1995 and a memorandum of understanding between the United Nations and the Iraqi government, OIP monitored the sale of Iraq’s oil and its purchase of commodities and the delivery of goods, and accounted for the program’s finances. The United Nations received 3 percent of Iraq’s oil export proceeds for its administrative and operational costs, which included the cost of U.N. weapons inspections. The sanctions committee’s procedures for implementing resolution 986 stated that independent U.N. inspection agents were responsible for monitoring the quality and quantity of the oil shipped. The agents were authorized to stop shipments if they found irregularities. OIP hired a private firm to monitor Iraqi oil sales at exit points. However, the monitoring measures contained weaknesses.
