Your audit firm was re-appointed the auditors of the bank for the year ended 31 October 2019. Charles Bwiri is the audit manager in charge of the audit of MCB Ltd. The interim audit for the year ended 31 October 2019 commenced on 1 April 2019. During the interim audit the auditors noted that MCB Ltd. had gradually changed its accounting system from a manual system to a computerized system as follows: Four branches were fully computerized. Two branches were in the process of being fully computerized. Two branches operated a manual system. Charles Bwiri assessed the bank risks as follows: 1. The four branches which were fully computerized were less risky because the internal control system in place was working as intended. In addition ,the employees of these branches were computer literate. 2. The two branches which were in the process of being computerized in the current year were riskier. This was because the internal control system of these branches had changed substantially and therefore needed greater focus. In addition, the computerized environment was new to the employees and they needed training in the operations of the computerized system. 3. The two branches which were operating a manual system were less risky. This was due to the fact that there were no changes in the internal control system and the working environment. Further, George Bwire had knowledge of the operations of these branches.
