The Bernina line was partly financed by revenue from transport rights. These transport rights were granted in return for rights of use for the Bernina line. This liability is amortised through the provision of energy transport services. Energy transport services will be provided on a pro rata basis throughout the line's useful life and the liabilities will be reduced accordingly over the same period.
