[1] | The consolidated statement of cash flows for 2019 has been restated to include operating, investing and financing activities from discontinued operations separately in the cashflow statement. In addition, the 2019 cash flow from investing activities has been restated to reflect reclassification of the cash flow hedges in relation to the Australia divestiture reported in the financing activities in 2019 and recycled to profit or loss upon the completion of the transaction.
