The sales figures, including but not limited to power sold and revenues received therefrom (the “Estimates”), of Korea Electric Power Corporation (“KEPCO”) as presented above have been prepared for convenience based only on the internal estimates of KEPCO as of the relevant meter reading periods and do not include (i) power sold and revenues received from pumped storage units and (ii) the fuel cost-based adjustment amounts. These figures have neither been audited nor reviewed by KEPCO’s independent accountants, Deloitte Anjin LLC., or any other accountants. These Estimates may differ significantly from the actual results of operations of KEPCO, which KEPCO expects to publicly disclose in the future in a number of ways, including but not limited to, elimination of internal profits and sales discount.
