Everyone within the IHL system has some role in regards to Internal Control. The roles vary depending on the level of responsibility and the nature of the involvement of the individual.

• Office of Internal Audit's (IA) role is to examine the adequacy and effectiveness of the internal control and make recommendations where control improvements are needed. Since IA is to remain independent and objective, it does not have the primary responsibility for establishing or maintaining internal control. However, the effectiveness of internal control is enhanced through the audits performed and recommendations made by IA.
