Cash at bank and in hand includes bank balances of $86m (2021: $67m) which are matched by bank overdrafts of $55m (2021: $59m) under the Group’s cash pooling arrangements. Under these arrangements, each pool contains a number of bank accounts with the same financial institution and the Group pays interest on net overdraft balances within each pool. The cash pools are used for
day-to-day
cash management purposes and are managed as closely as possible to a zero balance on a net basis for each pool. Overseas subsidiaries are typically in a cash-positive position with the matching overdrafts held by the Group’s central treasury company in the UK. Accordingly, bank overdrafts are included within cash and cash equivalents for the purposes of the cash flow statement.
