The corporation's internal audit has, to some degree, experienced a shift toward a value-adding focus in recent years. This shift is evidenced by the move to appoint multidisciplinary staff and to assign internal auditors in some SBUs. However, except that copies of audit reports are provided to the internal audit department at headquarters, the SBU's auditors' reporting responsibilities were to the respective SBU managers. This practice might challenge independence and objectivity; structuring the internal audit department at headquarters along
SBUs would rather improve the internal audit services.
