Recognition and measurement Cash and short-term deposits in the balance sheet comprise cash at bank and on hand and highly liquid cash deposits with short-term maturities and are readily convertible to known amounts of cash with insignificant risk of change in value. The Group considers that the carrying value of cash and cash equivalents approximate fair value due to their short term to maturity. Cash and cash equivalents includes US$98 million (2017: US$180 million) restricted by legal or contractual arrangements. Interest bearing liabilities and cash and cash equivalents include balances denominated in the following currencies:

Liquidity risk The Group’s liquidity risk arises from the possibility that it may not be able to settle or meet its obligations as they fall due and is managed as part of the portfolio risk management strategy. Operational, capital and regulatory requirements are considered in the management of liquidity risk, in conjunction with short-term and long-term forecast information. Recognising the cyclical volatility of operating cash flows, the Group has defined minimum target cash and liquidity buffers to be maintained to mitigate liquidity risk and support operations through the cycle. The Group’s strong credit profile, diversified funding sources, its minimum cash buffer and its committed credit facilities ensure that sufficient liquid funds are maintained to meet its daily cash requirements. The Group’s policy on counterparty credit exposure ensures that only counterparties of an investment grade standing are used for the investment of any excess cash. Standard & Poor’s credit rating of the Group remained at the A level with stable outlook throughout FY2018. Moody’s maintained their credit rating for the Group of A3 with positive outlook throughout FY2018. There were no defaults on loans payable during the period. Counterparty risk The Group is exposed to credit risk from its financing activities, including short-term cash deposits with banks and derivative contracts. This risk is managed by Group Treasury in line with the counterparty risk framework, which aims to minimise the exposure to a counterparty and mitigate the risk of financial loss through counterparty failure. Exposure to counterparties is monitored at a Group level across all products and includes exposure with derivatives and short-term cash deposits. Short-term cash deposits and derivatives are transacted with approved counterparties who have been assigned specific limits based on a quantitative credit risk model. The policy is reviewed annually and limits are updated at least bi-annually. Derivatives must be transacted with approved counterparties and are subject to tenor limits. Standby arrangements and unused credit facilities The Group’s committed revolving credit facility operates as a back-stop to the Group’s uncommitted commercial paper program. The combined amount drawn under the facility or as commercial paper will not exceed US$6.0 billion. As at 30 June 2018, US$ nil commercial paper was drawn (2017: US$ nil). The revolving credit facility has a five-year maturity ending 7 May 2021. A commitment fee is payable on the undrawn balance and an interest rate comprising an interbank rate plus a margin applies to any drawn balance. The agreed margins are typical for a credit facility extended to a company with the Group’s credit rating. Maturity profile of financial liabilities The maturity profile of the Group’s financial liabilities based on the contractual amounts, taking into account the derivatives related to debt, is as follows:
