Hi, Jim. Yes. I think the interest expense is probably accounted for by two things. First of all, we purchased a vessel. So, there's one extra vessel, 18 vessels now. If you look back previously, that obviously wasn't there. So that accounts for a chunk of interest expense. And plus one-third approximately 34% at March, is not hedged, is not linked to swaps. So, it's variable. And obviously LIBOR has gone from crazy low to quite high recently. So when you're looking at -- as at today, $350 million that is exposed to that LIBOR increase, yes, of course you're going to see a significant increase in quarterly and annual interest expenses. Where that goes from here, I think that's the jury is still out on whether the Fed will increase rates anymore. We've obviously got a fair amount of debt that is fixed, and as we're paying that down, you see on the diagram that, the proportion that swapped compared to total debt, actually increases for the next few years. So, we're going to be slightly better off in that respect. But yes, I think to the extent that the U.S. interest rates don't go higher, then yes, we've probably topped out in terms of interest expense. Perhaps the third element is as well, obviously, we've increasingly drawn on our revolving credit facilities and that obviously has also added to our overall interest expense. So again, that's one of the reasons why our key focus is on our visible liquidity going forward, to allow us to perhaps use those revolvers less, and reduce that borrowing in that respect as well. So, I think it's a combination of things. And possibly, it's topped out. But yes, it depends on what the U.S. Fed does going forward.
