I did ponder putting some sort of assessment of that in my remarks. It's quite challenging given that, as an export-oriented industry that exports over 70% of our products, there's a patchwork of countries that have a price on carbon and there are a significant number that don't. It's unclear from our industry's perspective whether or not this would, in fact, make them whole and be revenue-neutral.
The costs are myriad and quite opaque at this time, unfortunately. I'm sorry, but I don't have a better answer for you.
