At 30 June 2010 the Company has exposure to interest rate risk which is the risk that the Company’s financial position will be adversely affected by movements in interest rates that will increase the cost of floating rate project finance debts or opportunity losses that may arise on fixed rate convertible bonds in a falling interest rate environment. Interest rate risk on cash and short-term deposits is not considered to be a material risk due to the historically low US dollar interest rates of these financial instruments.
The Company’s main foreign currency risk is for monetary assets and liabilities of the Namibian and Malawian operations. These have a functional currency of US dollars, and the Company has adopted a presentation currency of US dollars therefore eliminating any foreign currency translation risk for non-monetary assets and liabilities. The Company also has significant foreign currency translation risk for non-monetary assets and liabilities of the Australian exploration and evaluation operations as these are deemed to have a functional currency of Australian dollars, and the Company has adopted a presentation currency of US dollars. The Company has no significant monetary foreign currency assets and liabilities apart from Namibian dollar cash, receivables, payables, deferred tax liabilities and provisions and Australian dollar cash, payables and deferred tax liabilities.
The Company currently does not engage in any hedging or derivative transactions to manage interest rate or foreign currency risks.
The Company’s credit risk is the risk that a contracting entity will not complete its obligation under a financial instrument that will result in a financial loss to the Company. The carrying amount of financial assets represents the maximum credit exposure. The Company trades only with recognised, credit worthy third parties. In addition, receivable balances are monitored on an ongoing basis with the result that the Company’s exposure to bad debts is not significant.
The Company’s treasury function is responsible for the Company’s capital management, including management of the long-term debt and cash as part of the capital structure. This involves the use of corporate forecasting models which enable analysis of the Company’s financial position including cash flow forecasts to determine the future capital management requirements. To ensure sufficient funding for operational expenditure and growth activities, a range of assumptions are modelled so as to provide the flexibility in determining the Company’s optimal future capital structure.
