Below is a PDF version of my spreadsheet. Please be advised you will not be able to see calculations however the annual reports (located above) will confirm the figures.
These figures used have been derived from the 2016 and 2018 annual report only due to the 2018 annual report adopting new IAS but not publishing a reconciled annual report.
Notes in the 2018 annual report do touch on the adjustments and the adoption of new IAS however I am unable to decypher it at this point in time.
