Okay. So let's divide this up a little bit. So in indoor units, virtually every competitor we have, has this capability because indoor units don't tend to be so commoditized, they're not an in-stock-on-the-shelf kind of a unit. They're built to order. So virtually everyone who's building indoor air handling units has the capability of providing a fan system that is capable of overcoming this. Indoor air handling units typically go with chiller water systems. For the products that we produce in Longview, Texas, we have a high percentage of buyers that are, what's called a, split system. They also include a condensing unit, and they have refrigerant run through their coils rather than chilled water. So when you're talking about those indoor split systems, you start narrowing this down a little bit. Because a lot of our competitors don't have a real effective offering of this style of split system with these kind of capabilities. So for many years, our successes of the split systems we produce in Longview were due to the attributes they had with some application strategies. In other words, a lot of projects with chilled water, which are typically your larger central projects -- central plant projects, we were able to duplicate that kind of performance with a split system and scale that down. So some projects need an indoor air unit because they don't have roof structure or roof square footage available for a rooftop unit. So that buys well for Longview. Now when we're talking about packaged rooftop units, when we're talking about units that are 25 tons and smaller, then virtually all of our competitors, with a small exception, and that would be Daiken, their fan systems will not accommodate this additional static pressure for these higher filtration requirements. So we have essentially 1 competitor that can match us on fan performance on these 25 ton and smaller units, and that would be Daikin. And when we look at it from a competitive standpoint, that's quite nice to compete against them. When we go above 25 tons, then it starts sprinkling in a few manufacturers here and there, between 25 and 50 tons, we'll say, that can do these sorts of things. Now once we get above 50 tons, then it becomes even more of those manufacturers are capable of doing that. So our most substantial opportunity is in the 2- through 25-ton sized equipment that our strategy and our value proposition are extraordinary. Water-source heat pumps. We do have a fan capability to step up the filtration capabilities in those. That was 1 of our innate designs. Because we recognizes this ability, even before coronavirus, that there were many applications that would desire a higher level of filtration. So as far as water-source heat pump manufacturers going head-to-head, we do have unique capabilities once again in that facet.
