Question 4b
​​Johanna Ltd. aims to be listed in the Nairobi Securities Exchange. Benjamin Mutie is the chief executive officer and chairman of Johanna Ltd. He appoints and maintains a board of only five executive directors. While the board sets the performance targets for the senior management in the company, no formal targets are set for each director and no review of the board policies is carried out. 

Board salaries are set and paid by Benjamin Mutie based on his assessment of all board members, including himself and not their actual performance. 

Internal controls in Johanna Ltd. are monitored by the senior accountant, although the company assumes that, as external auditors, your firm will carry out a detailed review of internal controls.
