MATHEMATICAL PROVISIONS - Benefit Plan 1



These values were obtained based on the following costing plan:

Active Participants: sum of the following portions: 1.8% on 50% of "PREVI Installment", 3% on the second half of the "PREVI Installment" and 7.8% on the difference between the participation-salary and the value of the "PREVI Installment". On the resulting value there is also 25% related to the semiannual bonus.

The contributions of the participants and sponsors are equivalent and obligatory, and correspond to 7% of the participation-salary.

Sponsors: value identical to that of the contributions of the participants.

In addition to these contributions, the costing plan of Benefit Plan 1 establishes, according to the contract signed between BB and PREVI - Group 67, that the Bank shall make contributions to maintain the equilibrium between the balances of the account "Mathematical Provisions to be Constituted" and of the account "Advanced Amortizing Contributions".
