RECOVERABLE VALUE OF LONG-TERM ASSETS |
RECOVERABLE VALUE OF LONG-TERM ASSETS | NOTE 20 – RECOVERABLE VALUE OF LONG-TERM ASSETS The Company estimates the recoverable value of its fixed and intangible assets based on value in use, which is measured based on the present value of the estimated future cash flow. The assumptions used consider the Company’s Management’s best estimate of future trends in the electricity sector and are based on both external sources of information and on historical data from the cash-generating units. The main assumptions defined below were considered:
| ● | Growth compatible with historical data and growth prospects for the Brazilian economy;
| ● | Discount rate per year in the year ended December 31, 2023, after taxes, specific to the segments tested: 5.81% and 6.53% for the generation segment without and with the SUDAM/SUDENE tax benefit, respectively (as of December 31, 2022, 4.82% for non-renewed generation without the SUDAM/SUDENE benefit, 5.58% for non-renewed generation and 5.20% for renewed generation with the benefit), taking into account the weighted average cost of capital;
| ● | The discount rate per year, before taxes, for the corporate ventures tested varies between 6.96% and 13.56%;
| ● | Revenues projected in accordance with the contracts, without provision for extending of the concession / authorization.
| ● | Expenses segregated by cash-generating unit, projected based on the Business and Management Master Plan (PDNG) for 5 years and consistent with the plan for the other years, until the end of the concessions and without considering future renewals / extensions; and
| ● | The Company treated each of its projects as independent cash-generating units.

​ Accounting Policy The Company periodically evaluates whether there is an indication of devaluation of its main non-financial assets. The valuation is carried out by Cash Generating Unit - CGU, that corresponds to a group of assets capable of generating cash inflows, that are largely independent of the cash inflows of other assets or other groups of assets. If there is an indication of devaluation, the recoverable amount of the CGU is estimated and compared with the current accounting balance. If the recoverable amount is lower than the book value, a loss is recorded with devaluation of the asset. ​ Estimates and critical judgements ​ The recoverable amount of the asset is the highest between either the value in use or the fair value. In summary, the value in use is the present value of future cash flows arising from the operation of the asset and the fair value is the price that would be received for the sale of the asset in a non-forced transaction. ​ Because there is no active market for the trading of its assets and because it believes that the calculation of fair value based on market assumptions would approximate the value in use, in most impairment tests, the Company admits as recoverable value the value in use, which corresponds to the present value of the estimated future cash flows, with a discount rate that reflects the Company’s current market valuation and/or opportunity cost, the value of the currency over time and the specific risks of the asset. ​ For the impairment tests of assets that the Company initiated studies for trading, not yet characterized in accounting terms as available for sale, the fair value is considered, being calculated on the basis of the average of the values of the proposals, not yet binding, received from possible interested parties.
