In the RIIO Price Controls, the Corporate Debt Expenditure (CDE) variable value is updated on an annual basis with reference to a trailing average index of debt costs. This model calculates CDE values that have been used for the Annual Iteration Process 2019 for all four RIIO Price Controls.
•For GD1, GT1, ED1 Fast-track and most ET1 licensees, the trailing index covers a 10-year period up to the 31 October 2019.
•For SHE-Transmission, the index also covers 10 years but with bespoke weightings.
•For ED1 Slow-track, the trailing index covers a 14-year period up to the 31 October 2019, and will extend by a year at each AIP.
