This excel spreadsheet provides stakeholders with the full WACC model used in preparing the Fact Sheet.
Please note: A version of this calculator was published on 23 August 2018 that contained a rounding error in the WACC Calculator worksheet. The error has been corrected for this version of the calculator. Changes were made to cells E82:E84 and G82:G84 of the “WACC Calculator” worksheet. See cell H82 of the “WACC Calculator” worksheet for more detailed explanation. We note that this error did not affect the August 2018 biannual market update fact sheet which shows the correct WACC estimates.
