Paragraphs:
Dividends are distributions of the Group’s profit after tax before significant items to its shareholders and represent one of the ways the Group distributes returns to its shareholders.
All dividends are fully franked at a 30% tax rate.
On 29 August 2019, the Board of Directors declared a final dividend in respect of the 2019 period of 57 cents per share, fully franked at a 30% tax rate. The amount will be paid on or around 30 September 2019 and is expected to be $717 million. As the dividend was declared subsequent to 30 June 2019, no provision had been made as at 30 June 2019.
The DRP remains active. Eligible shareholders may participate in the DRP in respect of all or part of their shareholding. There is currently no DRP discount applied and no limit on the number of shares that can participate in the DRP.
Shares will be allocated to shareholders under the DRP for the 2019 final dividend at an amount equal to the average of the daily volume weighted average market price of ordinary shares of the Company traded on the ASX over the period of 10 trading days commencing on 6 September 2019. The last date for receipt of election notices for the DRP is 5 September 2019. The Company may acquire shares on-market during this period to satisfy its obligations under the DRP.
During the period, 13.4% (2018: 39.9%) of the dividends paid were reinvested in shares of the Company. The change in the reinvestment participation rate reflects the removal of the discount with effect from the 2018 final dividend paid on 12 October 2018. The DRP in respect of the 2019 interim dividend was satisfied in full through the on-market purchase and transfer of $73 million of shares to participating shareholders.
