EMPLOYEE BENEFITS |
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, which has as members (and former employees) who have joined the fund. through a membership agreement, in addition to CBS employees themselves. The CBS Executive Board is made up of a president and two directors, all appointed by CSN, the main sponsor of CBS. The Deliberative Council is the decision-making and superior guidance body of CBS, composed of the president and ten members, six of them chosen by CSN and four of them elected by the participants. 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, 2020, CBS held 4,450,652 CSN common shares (1,870,652 as of December 31, 2019). The entity’s total guarantee resources totaled R$5.7 billion on December 31, 2020 (R$5.5 billion on December 31, 2019). 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, the 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 balance and actuarial, 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 (2017, 2018, 2019 and 2020), there was no need to pay installments by CSN, since the benefit plans defined actuarial gains in the year.
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 licensed by the Official Social Security and also guarantees the payment of savings, death and monetary assistance. This plan was deactivated 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 wages 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 deactivated 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 was 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 deactivated on September 16, 2013, when the CBSPrev plan came into effect. CBS Prev Plan On September 16, 2013, the new CBSPrev 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 a 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 CBSPrev plan, the Mixed Supplementary Benefit Plan was deactivated for the entry of new participants as of September 16, 2013. CBSPREV Namisa Plan It is a Defined Contribution plan with risk benefits during the activity (projection of the balances in case of disability or death and sickness / accident benefits). It has been in operation since January 6, 2012, when it was created to serve exclusively the employees of Nacional Minérios S / A. After the corporate reorganization, which took place in 2016, other Sponsors joined this Plan, among them, CSN Mineração SA In this plan, all benefits offered are calculated based on what has been accumulated by the monthly contributions of participants and sponsors and are paid through a percentage applied to the balance of the benefit generating fund. The CBSPREV Namisa Plan has been closed to the entry of new participants since July 2017 and in 2020 the plan’s extinction process was finalized due to the total withdrawal of sponsorship.
30.b) | Investment policy
The investment policy establishes the principles and guidelines that should govern the investment 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 study (Asset Liability Management), which takes into account 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 by 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”).

Accounting Policy Employee benefits - long term A defined contribution plan is a post-employment benefit plan under which the Company pays contributions to CBS, obligations for contributions to defined contribution pension plans are recognized as employee benefit expenses in the income statement during the periods during which they are paid. services are provided by employees. In this modality, the Company will have no legal or constructive obligation to pay additional amounts, as the risks fall on employees. In the defined benefit plan, obligations are assessed annually by independent actuaries, the unit credit method is used in the calculation, the assumptions for the calculation include biometric, demographic, financial and economic assumptions. The discount rate is applied to define the present value of the defined benefit obligations, the fair value of the assets is also determined. The amount recognized in the Company’s balance sheet is the net of obligations after the discount rate less the fair value of the assets. When the calculation results in a benefit to the Company, the asset to be recognized is limited to the total of any past unrecognized service costs and the present value of the economic benefits available in the form of future plan reimbursements or reduction in future plan contributions . Actuarial gains and losses resulting from defined benefit plans immediately in other comprehensive income. In the event of extinction of the plan, the accumulated actuarial gains and losses are recorded in income.
