Sure, let me give you a little context, just on kind of how it did move up, which I think will be helpful as well. The calculation we use in average debt is average debt to average EBITDA. We had, as you're aware, in particular in the fourth quarter, we had a large number of debt repayment last year, the average leverage of our repayments was 2.2 times in Q4. So, what I would say is very mature investments. We also had a big year of new investments, including 67 million in new originations in Q4 and 80 in Q1. The average leverage of our new investments has been around 4.5 times here, over the past 12 months. So we also encountered a high level of portfolio company acquisitions, which serves as a re-leveraging of our investments in some of those companies, at least most of the time as sponsors continue to use debt when feasible. All these facets that I just mentioned caused the ratio to change. A couple other points I'd make. As I mentioned on prior calls, we continue to focus on slightly larger companies from an investment perspective and sort of if you look at our average EBITDA, I do think it's risen. But it's not up dramatically, but it's up -- it's over $10 million today. And I think there was -- that's very different than it was, say four years ago. As you can imagine, larger companies, safer and more durable, theoretically, usually have higher leverage points as well. And that's to the point that you're asking. We feel great about the portfolio today. I will also add that the equity cushion for our portfolio, if you looked at it for -- our whole portfolio as one company, possesses an equity cushion of approximately 50%, provides us with what we believe a very high level, high margin of safety, for our debt investments. So hopefully, that's helpful, but the average has definitely gone up. And it's been a very, quite frankly, deliberate action by Fidus over the last several years to really focus on a little bit larger businesses in our core market.
