The Consolidated Entity has an investment in MM Mining Plc (MMM), an unlisted public UK company that explores for base metals. At 30 June 2010 the Consolidated Entity holds Nil (2009:20M) warrants. During the year all warrants were cancelled. Each warrant entitled it to acquire one fully paid ordinary share in MMM at an exercise price of 15 GB pence on or before 31 December 2012.
As MMM is unlisted the options were valued using the Black-Scholes option pricing methodology using the most recent market transaction to determine the appropriate underlying value.
