Forluz Pension plan (a Supplementary retirement pension plan) Company 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 of the sponsors. Company and its subsidiaries also maintain, independently of the plans made available by Forluz, payments of part of the life insurance premium for the retirees, and contribute to a health plan and a dental plan for the active employees, retired employees and dependents, administered by Cemig Saúde. Actuarial obligations and recognition in the financial statements 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, 2020. Debt with the pension fund (Forluz) The Company has recognized an obligation for past actuarial deficits relating to the pension fund in the amount of R$473 on December 31, 2020 (R$566 on December 31, 2019). 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. Agreement to cover the deficit on Forluz Pension Plan ‘A’ Forluz and the Company have signed a Debt Assumption Instrument to cover the deficit of Plan A for the years of 2015, 2016 and 2017. On December 31, 2020 the total amount payable by Cemig and its subsidiaries as a result of the Plan A deficits is R$540 (R$550 on December 31, 2019, referring to the Plan A deficits of 2015 and 2016). The monthly amortizations, calculated by the constant installments system (Price Table), will be paid until 2031 for the 2015 and 2016 deficits, in the amount of R$363, and up to 2033 for the 2017 deficit, in the amount of R$177. Remuneratory interest applicable to the outstanding balance is 6% p.a., plus the effect of the IPCA. If the plan reaches actuarial surplus before the full period of amortization of the debt, also Company will not be required to pay the remaining installments and the contract will be extinguished. In December, 2020, in accordance with the applicable legislation, Forluz proposed to Cemig a new Debt Assumption Instrument to be signed, if approved, by Forluz, Cemig, Cemig GT and Cemig D, in accordance with the plan to cover the deficit of Plan A, that occurred in 2019. The total amount to be paid by the Company to cover the deficit is R$160, through 166 monthly installments. The remuneration interest rate over the outstanding balance is 6% per year, plus the effect of the IPCA. If the plan reaches actuarial balance 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.
