GAO discussed the Department of State's Office of Munition Control's (OMC) arms export control activities to determine whether exporters complied with certain administrative and reporting requirements. GAO noted that OMC: (1) failed to routinely check export license application data and rarely verified purchasers' legitimacy; (2) has insufficient information processing capability; (3) needs to perform a long-term assessment of its information and equipment needs; (4) cannot ensure compliance with administrative requirements; (5) understates the value of export licenses and actual exports; and (6) processes most license applications within 30 days, even though its workload has increased and it has suffered staffing constraints.
