| (1) | This includes the impairment, in the amount of R$22 recognized in the Income Statement under “Other expenses”. The test of impairment of intangible assets, relating to the authorization for wind power generation granted to Volta do Rio, recognized in 2018 as part of the its business combination, arises from non-achievement of the operational performance expected in 2019 for the wind generation assets of the subsidiary. The Value in Use of the assets was calculated based on the projection of future expected cash flows for the operation of the assets of the subsidiary, brought to present value by the weighted average cost of capital defined for the company’s activity, using the Firm Cash Flow (FCFF) methodology.
| (2) | The transfers were made between Intangible assets, concession contract assets and property, plant and equipment are as follows: (1) R$685 from concession contract assets to intangible assets; (2) (R$4) from intangible assets to property, plant and equipment and; and (3) (R$23) from intangible assets to concession financial assets.
Concession assets The energy and gas distribution infrastructure assets already in service and that will be fully amortized during the concession term are recorded as intangible assets. Assets linked to the infrastructure of the concession that are still under construction are posted initially as contract assets, as detailed in Note 15. The main amortization rates, which take into account the useful life that management expects for the asset, and reflect the expected pattern of their consumption, are as follows:
Energy |  | (%) |  | Administration |  | (%)
System cable – below 69 KV |  |  | 6.67 |  |  | Software |  |  | 20.00 |
System cable – below 69 KV |  |  | 3.57 |  |  | Vehicles |  |  | 14.29 |
Structure – Posts |  |  | 3.57 |  |  | General equipment |  |  | 6.25 |
Overhead distribution transformer |  |  | 4.00 |  |  | Buildings |  |  | 3.33 |
Circuit breaker – up to 69 kV |  |  | 3.03 |  |  |  |  |  |  |
Capacitor bank – up to 69 kV |  |  | 6.67 |  |  |  |  |  |  |
Voltage regulator – up to 69 kV |  |  | 4.35 |  |  |  |  |  |  |
Gas |  | (%) |  | Administration |  | (%)
Tubing |  |  | 3.33 |  |  | Software |  |  | 20.00 |
Buildings, works and improvements |  |  | 4.00 |  |  | Vehicles |  |  | 20.00 |
Improvements in leased properties |  |  | 10.00 |  |  | Data processing equipment |  |  | 20.00 |
Machinery and equipment |  |  | 5.00 a 20.00 |  |  | Furniture |  |  | 10.00 |
The annual average amortization rate is 3.94%. The segregation by activity is as follows:
Hydroelectric Generation |  | Wind Power Generation |  | Gas |  | Distribution |  | Administration
| 7.44 | % |  |  | 8.81 | % |  |  | 3.33 | % |  |  | 3.83 | % |  |  | 15.82 | %
Under the regulations of the energy segment, property, plant and equipment used in the distribution concession are linked to these services, and cannot be withdrawn, disposed of, assigned or provided in guarantee without the prior express authorization of the Grantor. The rights of authorization of the gas distribution concession, granted to Gasmig, valued at R$396 (R$412 on December 31, 2020), and to generate wind power granted to the subsidiary Parajuru and Volta do Rio, in the total amount of R$116 (R$128 on December 31, 2020) are classified in the consolidated statement of financial position under intangibles assets and are amortized by the straight-line method, for the period of the concessions. The Value in Use of the assets was calculated based on the projection of future expected cash flows for the operation of the assets of the subsidiary, brought to present value by the weighted average cost of capital defined for the company’s activity, using the Firm Cash Flow (FCFF) methodology. Renegotiation of hydrological risk – the Generation Scaling Factor (GSF) On September 9, 2020, the Law 14,052 was passed aiming to compensate holders of hydroelectric plants for the costs incurred due to the GSF, under the Energy Reallocation Mechanism (MRE) for the period from 2012 to 2017, during which there was hydrological crisis The aim of this new law is to compensate the holders of hydroelectric plants participating in the MRE for , and the following non-hydrological risks were incurred by the hydroelectric plants holders:
| (i) | generation ventures classified as structural, related to bringing forward of physical guarantee of the plants;
| (ii) | the restrictions on start of operation of the transmission facilities necessary for outflow of the generation output of structural projects; and
| (iii) | generation outside the merit order system, and importation.
This compensation in the form of an extension of the term of the concession or authorization to operate, limited to 7 years, calculated on the basis of the parameters applied by Aneel. On December 1, 2020, Aneel issued its Normative Resolution 895, which established the methodology for calculation of the compensation, and the procedures for renegotiation of hydrological risk. To be eligible for the compensations under Law 14,052, the holders of hydroelectric plants participating in the MRE are required to:
| (i) | cease any legal actions which claimed exemption from or mitigation of hydrological risks related to the MRE;
| (ii) | relinquishing any claims and/or further legal actions in relation to exemptions from or mitigation of hydrological risks related to the MRE; and
| (iii) | not to have renegotiated hydrological risk under Law 13,203/2015.
On June 11, 2021, the Board of Directors authorized withdrawal of any legal proceedings based on the MRE, and the signing of the Term of Acceptance of Law 14,052/2020 provisions, for the plants within the concession contracts of Cemig GT and subsidiaries. With the approval by the Board of Directors, the Company recognized, on the second quarter of 2021, an intangible asset relating to the right to the extension of concessions, with counterpart in “Operational costs – Renegotiation of Hydrological risk (Law 14,052/20)”, in the amount of R$910. On August 03, 2021, Aneel ratified, through the Resolution nº. 2,919/2021, the terms of concession extension of hydroelectric plants participating in the MRE, including all of the Company’s plants qualified for the renegotiation, except for Queimado and Irapé, which renegotiate the hydrological risk through the Resolution nº. 684/2015 and were not covered by the Resolution nº. 2,919/2021. The values ratified are aligned with the Company estimations, based on the Resolution Aneel nº. 895/2020. On September 14, 2021 Aneel ratified the grant extension of the hydroelectric plants participating in the MRE, through Resolution (ReH) 2,932/2021, including Irapé and Queimado, for which the extensions were under discussion with the Grantor, and, therefore, were not included in ReH 2,919/2021. Thus, in the third quarter of 2021, there was a recognition of an increase of R$122 in Intangible assets, due to the concessions extension of those plants. As a result, the total of Intangible assets was increased to R$1,032, which is recognized as a decrease in Operational costs, as Renegotiation of hydrological risk – Law 14,052/20. The fair values of the concessions extension rights have been estimated individually, as shown in the table below, using the revenue approach, under which future values are converted into a single present value, discounted by the rate of profitability approved by Management for the energy generation activity, reflecting present market expectations in relation to the future amounts. The useful life of items that are components of Intangible assets has been adjusted for the new remaining concession period, that is the result of addition, to the original concession period, of the new concession extension granted.

The Resolution nº. 2,919/2021 ratified the amount of the right to compensation for the São Simão, Jaguara, Miranda and Volta Grande generation plants, which had been owned by Cemig GT during the period stipulated in the Law 14,052/20, but does not specify how this compensation will happen in the event of absence of debts with the Federal Government related to the regime of concessions determined in that Law. The amounts calculated are: Schedule of power plant offer for tender

São Simão |  |  | 783 |

Jaguara |  |  | 237 |
Volta Grande |  |  | 157 |
Total |  |  | 1,322 |
Considering that there is no legal provision relating to how to settled the compensation of these non-hydrological risks will happen and such compensation depends on the occurrence of uncertain future events, which are not totally under its control, these contingent assets have not been recognized.
