It has been very challenging. As we know, very few of the more common materials have continued to be made in North America, so we have attempted to source most of them internationally at the same time as the world is sourcing those materials.
In working with the Government of Canada, we were the purchasing agent for a very large number of masks and other supplies, which unfortunately did not come to fruition, in the order of 100 million masks.
Unfortunately we have not seen the large international orders realized and landed on the ground. This was complicated slightly, I think, by transport through the continental United States. There was an expectation that orders would be shipped to Canada, but at one point the United States government made some changes in what they were willing to ship outside of the country.
