Post-employment Benefits
21. Post-employment Benefits
The company sponsors pension plans for supplementary retirement and pension benefits and a health and dental care plan for its active employees and their legal dependents. The lifetime sponsorship of the Assistance Plan for retirees, pensioners and legal dependents only applies to participants in the Prosaúde II Plan. Fundação Copel de Previdência e Assistência is the entity that administers these plans.
21.1. Pension plan and Assistance Plan
The Unified Plan is a Defined Benefit plan - BD in which the income is predetermined, according to each individual's salary. This plan is closed for new participants since 1998.
The Plan III is a Defined Contribution plan - CD in the contributory phase and, after retirement, it becomes a Defined Benefit plan - BD.
Plan IV, the only plan available to new participants, is a Defined Contribution plan - DC in which the entity's legal or constructive obligation is limited to the amount it agrees to contribute to the fund. Therefore, the amount of the post-employment benefit received by the employee must be determined by the amount of contributions paid by the sponsoring entity and also by the employee, together with the return on investments resulting from the contributions. Consequently, the actuarial risk (the risk that the benefits will be lower than expected) and the investment risk (the risk that the assets invested will be insufficient to cover the expected benefits) are the responsibility of the employee.
The Company allocate resources for the coverage of healthcare expenses incurred by their employees and their dependents, within rules, limits and conditions set in ProSaúde II and ProSaúde III Assistance plans regulations. Coverage includes periodic medical exams in both plans and is extended to all retirees and pensioners for life only in the ProSaúde II plan.
