4.4.2 Interest rate risk management

Fluctuations in interest rates could increase or reduce the costs of new loans and existing contracted operations.

The Company is constantly looking for alternatives for the use of financial instruments in order to avoid negative impacts on its cash flow due to fluctuations in interest rates in Brazil or abroad.

4.4.2.1 Sensitivity analysis – exposure to interest rates – except for derivative financial instruments

For its market risk analysis, the Company uses scenarios to evaluate the sensitivity of changes in operations impacted by the following rates: Interbank Deposit Rate (“CDI”), Long Term Interest Rate (“TJLP”), Long Term Rate ("TLP"), Special System for Settlement and Custody (“SELIC”) and SOFR, which could impact the results. The probable scenario represents the amounts already booked, as they reflect Management’s best estimates.

This analysis assumes that all other variables, particularly exchange rates, will remain constant. The other scenarios considered a variation of 25% and 50% in market interest rates.
