| 30. | EMPLOYEE BENEFITS
The pension plans granted cover substantially all employees. The plans are managed by Caixa Beneficente dos Empregados de CSN (“CBS”), a private, non-profit pension fund established in July 1960. Until December 1995, CBS Previdência managed two defined benefit plans based on years of service, salary and social security benefits. On December 27, 1995, the then Supplementary Pension Secretariat (“SPC”) approved the implementation of a new benefit plan, effective as of that date, called the Supplementary Benefit Mixed Plan (“Mixed Plan”), structured under the form of a variable contribution plan, which has been closed to new members since September 2013. As of that date, all new employees must join the CBSPrev Plan, structured in the form of defined contribution, also created in September 2013. The CBS guarantee funds are mainly invested in repo operations (backed by federal government bonds), federal government bonds indexed to inflation, stocks, loans and real estate. As of December 31, 2022 and 2021, CBS held 3,486,252 CSN common shares. The entity’s total guarantee resources totaled R$5.9 billion as of December 31, 2022 (R$5.8 billion as of December 31, 2021). CBS fund managers seek to combine plan assets with long-term benefit obligations to be paid. Pension funds in Brazil are subject to certain restrictions related to their ability to invest in foreign assets and, consequently, these funds invest primarily in securities in Brazil. Guarantee Funds are considered to be the available and investment assets of the Benefit Plans, not including the amounts of debts contracted with sponsors. For defined benefit plans, called “35% of Average Salary” and “Supplementary Average Salary Plan”, the Company maintains a financial guarantee with CBS Previdência, the entity that manages the aforementioned plans, in order to maintain the financial and actuarial balance, should any future actuarial loss or actuarial gain occur. In compliance with current legislation, specific to the pension fund market, for the last 4 years ended (2019, 2020, 2021 and 2022), there was no need to pay installments by CSN, since the benefit plans presented actuarial gains in the year. In August 2022, CSN Cimentos Brasil S.A. (formerly LafargeHolcim) was acquired and, consequently, Plano Mauá Prev was introduced in the Group. CSN Cimentos Brasil also sponsors the Mauá Prev Retirement Plan for its employees. This is the plan that LafargeHolcim in Brazil made available to all its employees as of December 1, 2016. Until 2009, Lafarge Brasil S.A. sponsored two plans, a defined contribution plan and a defined benefit plan. On July 1, 2009, the plans were merged, remaining only one variable contribution plan, with the exception of the acquired right of those who had already completed the eligibility of the defined benefit rules. The following tables present a summary of the components of the net defined benefit expense of Mauá Prev recognized in the income statement, as well as the capitalization status and amounts subject to recognition in the balance sheet as at December 31, 2022 and 2021.
| 30.a) | Description of pension plans
Plan of 35% of the average salary This plan started on February 1, 1966 and is a defined benefit plan, the purpose of which is to pay retirement benefits (length of service, special, disability or old age) for life, equivalent to 35% of the adjusted average of the last 12 salaries of the participant. The plan also guarantees the payment of sickness benefit to the participant retired by the Official Social Security and also guarantees the payment of savings, death, and monetary assistance. This plan was discontinued on October 31, 1977 when the plan to supplement the average salary came into effect. Average salary supplementation plan This plan started on November 1, 1977 and is a defined benefit plan. Its objective is to complement the difference between the corrected average of the last 12 salaries of the participant and the benefit of the Official Social Security for retirements, also for life. As with the 35% plan, there is coverage for sickness benefit, death benefit and pension benefits. This plan was discontinued on December 26, 1995, with the creation of the mixed supplementary benefit plan. Mixed supplementary benefit plan Started on December 27, 1995, it is a variable contribution plan. In addition to the programmed retirement benefit, payment of risk benefits (active pension, disability and sickness/accident benefits) is also provided. In this plan, the retirement benefit is calculated based on what has been accumulated by the monthly contributions of the participants and the sponsors, as well as the option of each participant in the form of receiving the same, which can be for life (with or without continuity of pension for death) or by a percentage applied to the balance of the benefit-generating fund (loss for an indefinite period). After retirement, the plan will have the characteristic of a defined benefit plan, if the participant has opted to receive his benefit in the form of lifetime monthly income. This plan was discontinued on September 16, 2013, when the CBS Prev plan came into effect. CBS Prev Plan On September 16, 2013, the new CBS Prev pension plan began, which is a defined contribution plan. In this plan, the retirement benefit is determined based on what has been accumulated by the monthly contributions of participants and sponsors. The option of each participant to receive it can be: (a) receive part in cash (up to 25%) and the remaining balance through monthly income for a percentage applied to the benefit-generating fund, not being applicable to death pension benefits, (b) receive only monthly income for a percentage applied to the benefit-generating fund. With the creation of the CBS Prev Plan, the Mixed Supplementary Benefit Plan was discontinued for the entry of new participants as of September 16, 2013. Mauá Prev Plan The Mauá Prev plan is offered by CSN Cimentos Brasil S.A. (formerly LafargeHolcim) acquired in 2022, and sponsors the Mauá Prev Retirement Plan, for its employees. This is the plan that LafargeHolcim in Brazil made available to all its employees as of December 1, 2016. Until 2009, Lafarge Brasil S.A. sponsored two plans, a defined contribution plan and a defined benefit plan. On July 1, 2009, the plans were merged, remaining only one variable contribution plan, with the exception of the acquired right of those who had already completed the eligibility of the defined benefit rules. Additionally, the Company has recorded in a collective agreement in some of its plants commitments related to the bonus, due on the occasion of the retirement of the employee by the Social Security. The following tables present the commitments related to this bonus, as well as the capitalization status and the amounts subject to recognition in the balance sheet
| 30.b) | Investment policy
The investment policy establishes the principles and guidelines that should govern the investments of resources entrusted to the entity, with the objective of promoting the security, liquidity and profitability necessary to ensure the balance between the plan's assets and liabilities, based on the ALM (Asset Liability Management) study, which considers the benefits of the participants and beneficiaries of each plan. The investment plan is reviewed annually and approved by the Deliberative Council, considering a 5-year horizon, as established in CGPC resolution No. 7 of December 4, 2003. The investment limits and criteria established in the policy are based on Resolution 4,661/18, published by the National Monetary Council (“CMN”).
