You are an employee of CoE and also sit on its board of directors. When CoE acquired a 48% stake in CoA as a joint venture 5 years ago, you were nominated to the board of CoA by CoE. CoA's profitability has been due in part to a lease, on very favourable terms, of factory premises that has been extended by CoE to CoA for the last 5 years. You understand that this arrangement was the result of the early negotiations between CoE and the only other shareholder of CoA, and appears to underpin the joint venture. The board of CoE has recently called a board meeting to decide whether to terminate the lease arrangement. What are your obligations?
