Thank you for the question.
The error was made back in late 2021. The modelling that we used, a computable general equilibrium model, essentially combined...because there's one carbon price in the carbon pricing system and that carbon price affects both the fuel charge and the output-based pricing system.
That price was set to zero in our counterfactual, but it was hitting both parts of the system. We had thought that it was only that one part, the fuel charge, but it was both parts. That was the error, but in our April 17 notice we still believe that it doesn't invalidate our analysis—
