Yeah, Dave thanks for the question. On the vast majority of our customers would fall into the camp of, what we would call, the carriers and then large enterprises. That would make up more than two-thirds of the base of revenues. And specifically on the large enterprise, we're heavily skewed towards health care, education and financial services.So if you were to take those three large components that's going to -- along with the carriers that's going to make up the vast majority of our revenues. And as I mentioned earlier and you referenced it, less than 5% of the revenues are coming from small and medium businesses.So, obviously, when you think about healthcare education and financial services, that customer base, we think, is less likely to be impacted by COVID. And as we look at the new lease bookings that we saw during the month of March and, as you know, our business is heavily weighted towards the Northeast corridor, which in many industries and aspects was shut down in the second half of March, we didn't see any impact in the month of March. In fact, we had a very good showing in the month of March, even as we were booking new revenues.As I mentioned in my comments, there are some places and some facilities where customers who have committed to use our service and need the bandwidth from us, have delayed our ability to access their facilities as a result of COVID-19, but we think that's a relatively short impact.So once there are protocols in place and we're able to access the facilities, then we'll go in and be able to add the additional bandwidth and bring the service to those customers. So, I think, in terms of our exposure, both in terms of what the direction of that is and then how we've seen that play out over the last six weeks, I think, our business there has -- we'll see very little to no impact from COVID-19.
