b.2) Compensator fund plan
This benefit is available to all Pesa employees who joined the defined contribution plans in force in the past and who joined the company prior to May 31, 1995 and have accumulated the required time of service. The benefit is calculated in complement to the benefits awarded under these plans and by the retirement system, so that the total benefit received by each employee is equivalent to the amount defined in this plan.
In accordance with Pesas bylaws, based on a proposal made in the general meeting by the board of directors, the Company contributes to the fund up to a maximum amount equal to 1,5% of the net income each year.
If a surplus is recorded and duly certified by an independent actuary in the funds allocated to trusts for payment of the defined benefits awarded by the plan, Pesa may use these funds simply by notifying the trustee of this fact.
