To use a tired expression, there's an apples and oranges problem here. We do our very best to do a strict economic comparison, but the tax rates are different in different jurisdictions. For example, in the gulf coast and Texas, tax rates are set by the local parishes. Those parishes have different rates and different rules from the municipalities. The municipality tax rates are assisted and guided by provincial rules.
The answer to your question is that we made a risk-based decision on which investment climate we thought was the best for the first investment of many in deep decarbonization. These tax credits have a value based on how much we believe we will be able to use them as we build a new facility and expand the existing facility we have in Fort Saskatchewan.
