CEMIG and its subsidiaries are sponsors of Forluz - Forluminas Social Security Foundation, a non-profit legal entity whose object is to provide its associates and participants and their dependents with a finance income to complement retirement and pension, in accordance with the pension plan that they are subscribed in.

Forluz provides the following supplementary pension benefit plans available to its participants:

Mixed Benefit Plan (‘Plan B’): This plan operates as a defined-contribution plan in the fund accumulation phase for retirement benefits for normal time of service, and as a defined-benefit plan for disability or death of participants still in active employment, and for receipt of benefits for time of contribution. The Sponsors match the basic monthly contributions of the participants. This is the only plan open for joining by new participants. The actuarial risks related to Plan B occur only as from the option for the lifetime benefit at the moment of the participant’s retirement. In this specific case the responsibility for the risk of insufficiency of reserves for coverage of the benefits (deficits) is in parity between sponsors and participants.

Funded Benefit Plan (‘Plan A’): This plan includes all currently employed and assisted participants who opted to migrate from the Company’s previously sponsored defined benefit plan and are entitled to a benefit proportional to those balances. For participants who are still working, this benefit has been deferred to the retirement date. The benefit balances of Plan A have the characteristic of lifetime payment, and the responsibility for the risk of insufficiency of reserves to cover the benefits (deficits) is exclusively that of the sponsors.

In addition to the Forluz pension plans, Cemig, Cemig GT and Cemig D , contribute to the Integrated Health Plan (PSI) and premium plan, and a dental plan for the active employees, retired employees and dependents, administered by Cemig Saúde.

As from December 2022, Cemig Saúde offered all active employees of Cemig an alternative, new, health plan, called the Premium Plan, in substitution of the Integrated Health Plan (PSI) that was in effect up to that date. The Premium Plan is financed entirely by the Company. In counterpart to the Company bearing the entire cost, those employees who accept the new plan will no longer receive the contribution from Cemig for payment for the health plan in their retirement. The adherence period to the new plan under the proposed conditions was available to employees up to January 31, 2023, and migration of some of the employees to the Premium Plan reduced the number of employees covered by the PSI.

In light of IAS 19 this situation constitutes a curtailment event, requiring the Company to remeasure its post-employment liabilities for the base date March 31, 2023. The effects of the curtailment have been recognized in the statement of income as a cost of past service, in the amounts of R$55 for the health plan and R$1 for the dental plan.

The curtailment event that was recognized for the quarter affected the actuarial assumptions, in that it altered the discount rates applicable to the plans. Since the new discount rate was higher, there was a reduction of the liability, and as a result an actuarial gain of R$60 for the health plan, and R$1 for the dental plan.

On this Note the Company discloses its obligations and expenses incurred for purposes of the Retirement Plan, Health Plan, Dental Plan and the Life Insurance Plan in accordance with the terms of IAS 19 - Employee Benefits, and the independent actuarial opinion issued as of December 31, 2023.

Forluz and the sponsors CEMIG, CEMIG GT and CEMIG D have signed a Debt Assumption Instrument to cover the deficit of Plan A for the years of 2015, 2016 and 2017.

The monthly amortizations, calculated by the constant installments system (Price Table), will be paid up to 2031 for the 2015 and 2016 deficits, in the amount of R$344, and up to 2033 for the 2017 deficit, in the amount of R$177. Remuneratory interest applicable to the outstanding balance is 6% p.y., plus the effect of the IPCA. If the plan reaches actuarial surplus before the full period of amortization of the debt, the Company will not be required to pay the remaining installments and the contract will be extinguished.

On December 31, 2023 the total amount payable by Cemig and its subsidiaries as a result of the Plan A deficits was R$521 (R$545 on December 31, 2022 referring to the Plan A deficits of 2015, 2016 and 2017).

In accordance with the specific legislation, Forluz sent Cemig a proposal to enter into new Private Debt Assumption Instruments between Forluz and the sponsors Cemig, Cemig GT and Cemig D, according to the settlement plan to cover the deficit of Forluz's Plan A in 2019, 2020 and 2021. In the case of deficit settlements, if the plan reaches actuarial balance before the full amortization period of the contract, the Company would be exempt from paying the remaining installments and the contract would be extinguished.

The Company, recognizing its legal obligation with regard to the Plan A deficit, corresponding to 50% of the minimum amount, respecting the rule of contributory parity, makes consignment payments into a judicial deposit account, which are available to Forluz to be redeemed at any time at the official bank. The deposits are constituted monthly by the amount of 50% of the installment of each of the 2019, 2020 and 2021 Deficit Equalizations, as follows:

Regarding the resolution of the 2019 deficit, Forluz, due to (i) the non-execution of the Debt Assumption Agreement to cover the minimum proposed amount in the plan for the actuarial deficit of Plan A in 2019, and (ii) the refusal of the Company's consignment payments. Forluz entered with a lawsuit on April 27, 2021, against sponsors Cemig, Cemig GT, and Cemig D. The lawsuit requests approval for enforcing the debt agreement in order to cover the consolidated deficit of R$160, in the same amount.

In 2022 the first instance of the Employment Law Appeal Court of Minas Gerais gave a decision in favor of Forluz, and against the Company’s requests, however, this discussion can be conduced in higher courts. As a result the Company, based on the assessments of its specialists, has opted to maintain its assessment of the chances of loss in the action as ‘possible’.

On December 31, 2023, the Company recognized an obligation for past actuarial deficits relating to the pension fund in the amount of R$90 on December 31, 2023 (R$251 on December 31, 2022). This amount has been recognized as an obligation payable by CEMIG and its subsidiaries, and will be amortized until June of 2024, through monthly installments calculated by the system of constant installments (known as the ‘Price’ table) and adjusted by the IPCA (Expanded National Customer Price) inflation index (published by the Brazilian Geography and Statistics Institute - IBGE) plus 6% per year. The Company is required to pay this debt even if Forluz has a surplus, thus, the Company maintain recorded the debt in full, and record the effects of monetary updating and interest in finance income (expenses) in the statement of income.

The Company CEMIG GT and CEMIG D have expectation of making contributions to the pension plan in 2023 of R$186 for amortization of the deficit of Plan A, and R$84 for the Defined Contribution Plan (recorded directly in the Statement of income for the year).

Below is a sensitivity analysis of the liabilities effect of changes in the main actuarial assumptions used to determine the defined-benefit obligation on December 31, 2023:

In the presentation of the sensitivity analysis, the present value of the defined-benefit obligation was calculated using the Projected Unit Credit method, the same method used to calculate the defined-benefit obligation recognized in the Statement of financial position.

The average maturity periods of the obligations of the benefit plans, in years, are as follows:

The Company has not made changes in the methods used to calculate its post-employment obligations for the years ended December 31, 2023 and 2022.

Expenses related to the debt agreed upon with the pension trust fund were recorded in finance income (expenses), because they represent financial interest and inflation adjustment. Other expenses related to the pension fund were recorded as operating expenses.

In the case of retirement obligations, the liability recognized in the balance sheet with respect to defined benefit pension plans is the greater of the debt agreed with the foundation for amortization of actuarial obligations and the present value of the actuarial obligation, calculated by means of an actuarial report, less the fair value of the plan's assets.

The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using the rate of return on high-quality corporate bonds that have terms similar to the duration of the respective pension plan obligations and are denominated in the currency in which the benefits will be paid.

In defined contribution plans, the Company makes fixed contributions and has no legal or constructive obligations to make contributions if the fund does not have sufficient assets to pay all employees the related benefits. The Company has no additional payment obligation after the contribution is made. Contributions are recognized as an employee benefits expense when due.

In the case of the health and dental plans, the liabilities are calculated by calculating the present value of the future obligations to be made by the Company, considering the maintenance of the current contribution level, the forecast of a real readjustment of the amounts and the future updating of the contributions by the variation of an index compatible with the Regulations and the history of the costs of the plans.

Actuarial calculations take place at each financial year end and involve the use of assumptions about discount rates, expected rates of return on assets, future salary increases, mortality rates and future increases in retirement and pension benefits. All assumptions are reviewed at each base date.

In the current and previous years, post-employment expenses are recorded as operating expenses, with the exception of expenses related to the debt agreed with the Pension Fund, which are recorded in the financial result, as they represent interest and monetary variation.

Actuarial gains and losses arising from adjustments based on experience and changes in actuarial assumptions are recognized through other comprehensive income and will not be reclassified to profit or loss in the future.

Both the past service cost resulting from a change or reduction in the defined benefit plan and the gain or loss on the settlement of obligations are determined based on the remeasurement of the net present value of the obligation, due to the revision of actuarial assumptions, and are recognized directly in profit or loss for the year in which the change occurs.
