So, as I said, Ivy, we are -- we scrub our backlog and are very proactive to understand where our customers are and the ones that have a home to sell, home to close. I think last time I looked at the -- a couple of weeks ago, I think it was about 6% or 7%, had a contingency in the backlog.And as, I believe, Dave mentioned in our prepared remarks, we're taking a second look at our backlog before we begin construction. And we want to make sure we have full visibility if we're considering starting a new home for a customer.Nothing is 100% Ivy, but I think it absolutely reduces our risk. And I think we've demonstrated over time, with our very low can rate, the tight controls we have in our backlog.So, I feel pretty good. Part of the TMHF process has also been tracking all COVID-related risks, on furloughs, and job losses, and pay cuts. So, we've been paying very close attention and have a pretty rigorous process in place on the backlog. And I said -- like I said, got very aggressive.I guess, lastly, what I share is when I look at the progress in our can rate over the last, oh, my goodness, four, five, six weeks, it would have started six weeks ago at something like 50%. And this past week, it's single-digits. So, I think we're getting back to a pretty normalized place on the backlog.
