Cash and cash equivalents comprise cash at bank and on hand, demand deposits with banks and other financial institutions, and short-term, highly liquid investments that are readily convertible into known amounts of cash and which are subject to an insignificant risk of changes in value, having been generally within three months of maturity at acquisition. Bank overdrafts that are repayable on demand and form an integral part of the Group’s cash management are also included as a component of cash and cash equivalents for the purpose of the consolidated cash flow statements.
