The preceding estimate, as discussed in Section 2, is based on the assumption of a
commercial WACC. In practice, the government may wish to accept a lower return on
equity than a private investor would require, enabling the allowed return to be reduced
(independently of whether donor financing also allows reductions). For example, if
the government did not require any return on its shareholding in KEK, then this would
reduce the estimated WACC from 10.8% to 4.9%.
