Basically, we looked at a number of assumptions. As we say in the report, some of these assumptions were overestimated, and they were based on non-existent policies. The report provides numerous examples.
As an example, there was an assumption for very low-cost electricity by provinces, where the assumption was $40-per-megawatt power across all provinces, whereas the observed price in 2020 ranged between $52 and $124 per megawatt. Some of these assumptions were definitely quite off as to the market value of some of those electricity costs.
