I don't think I have a single number for you, because it really depends on the timing.
As I mentioned in my opening remarks, there are a couple of critical windows in the spring and fall when fertilizer is applied each year. If there are disruptions in the supply chain in the spring or fall or leading into those seasons, they have a disproportionately high impact not only from an economic perspective but also for the downstream users of our products.
The export of fertilizer is a little bit more continuous in terms of impacts. If there's a rail disruption, we can look at the number of days or weeks when that's impacting the ability for goods to be moved to export markets. We've done analyses and assessments in the past when there were rail disruptions and supply disruptions. If there's a one-day labour strike that's impacting service at a class 1 railway, that's not a one-day impact to those users of the railway. It's one to two weeks of disruptions, because, as has been mentioned by some of the other experts here, the disruptions don't start the day the strike is called; they start two weeks ahead of time, when service is being curtailed and products are being pulled off the rails.
