You have picked one of the more complex annual reports to decipher. This is my calc for underlying earnings
Operating EBITDA 58747 Equity accounted earnings of associates 2521 DA -11242 Abnornal depreciation of IT system 3500 EBIT 53526 Interest -7926 NPBT 45600 TAX @28% 12768 NPAT 32832 eps 0.043
Further, I expect PGW is provide dividends that are approx 100% of earnings.
Remember earnings do not equal cashflow. Operating Cashflow - capex allows the payment of dividends. Sometime increasing debt can be used as well.
