Key Points

- Annual fee structure: All listed fees are charged annually at the date of signature of the contract and exclusive to taxes.
- Large-scale deployments: Class I pricing is negotiated based on specific situations.
- Predictable updates: Prices are reviewed every two years, with changes announced six months before they are applied, in January of the following year.
