KK is a large listed company. When a non-executive directorship of KK Limited became available, John Soria was nominated to fi ll the vacancy. John is the brother-in-law of KK’s chief executive Ken Kava. John is also the CEO of Soria Supplies Ltd, KK’s largest single supplier and is, therefore, very familiar with KK and its industry. He has sold goods to KK for over 20 years and is on friendly terms with all of the senior offi cers in the company. In fact last year, Soria Supplies appointed KK’s fi nance director, Susan Schwab, to a non-executive directorship on its board. The executive directors of KK all know and like John and so plan to ask the nominations committee to appoint him before the next AGM. KK has recently undergone a period of rapid growth and has recently entered several new overseas markets, some of which, according to the fi nance director, are riskier than the domestic market. Ken Kava, being the dominant person on the KK board, has increased the risk exposure of the company according to some investors. They say that because most of the executive directors are less experienced, they rarely question his overseas expansion strategy. This expansion has also created a growth in employee numbers and an increase in the number of executive directors, mainly to manage the increasingly complex operations of the company. It was thought by some that the company lacked experience and knowledge of international markets as it expanded and that this increased the risk of the strategy’s failure. Some shareholders believed that the aggressive strategy, led by Ken Kava, has been careless as it has exposed KK Limited to some losses on overseas direct investments made before all necessary information on the investment was obtained. As a large listed company, the governance of KK is important to its shareholders. Fin Brun is one of KK’s largest shareholders and holds a large portfolio of shares including 8% of the shares in KK. At the last AGM he complained to KK’s chief executive, Ken Kava, that he needed more information on directors’ performance. Fin said that he didn’t know how to vote on board reappointments because he had no information on how they had performed in their jobs. Mr Kava said that the board intended to include a corporate governance section in future annual reports to address this and to provide other information that shareholders had asked for. He added, however, that he would not be able to publish information on the performance of individual executive directors as this was too complicated and actually not the concern of shareholders. It was, he said, the performance of the board as a whole that was important and he (Mr Kava) would manage the performance targets of individual directors. Required:

(c) Explain the typical contents of a ‘best practice’ corporate governance report within an annual report and how its contents could help meet the information needs of Fin Brun. (10 marks)
