Yes, we've been very active in managing our working capital, obviously, looking at what we refer to as our cash gap. Our days of inventory, and our DSO offset by our days payable. Overall, we feel we're in a very strong position, it really starts with the collectability, which as I mentioned, has driven down our provision for bad debts. You know, we've improved the not only the balance of AR, if you look at our disclosures, we've taken 10s of millions of dollars out of our AR balances over a horizon where that top line has grown meaningfully. And that's really a testament to our patient registration in our billing teams, who are converting that that revenue to cash significantly faster, that has afforded us to manage and reduce our overall working capital balance, as you'll also see with inventory, they also affords us the ability to make some strategic investments in PPE and med supplies in what we think could be some challenge supply markets going forward. And so we've been making some strategic elections on our working capital and investments where we think it's prudent. So overall, I think, working capital, you know, you asked the teams out in the field, they're just getting started, and they think there's continued efficiency, and we would agree with that. So overall, I think working capital will be relatively neutral and probably grow modestly, as a fraction of revenues going forward. You know, with the bad debt. You're absolutely right, as we think about the different therapies. One of the benefits on the chronic therapies is these are a higher cost regiment. Virtually all of our chronic starts are prior authorized by the payers. And so we typically see a lower bad debt profile for our chronic therapies, simply because our patient registration teams are so diligent around following up with payers who obviously want to have some involvement in the treatment regimens for those therapies. So, overall, with the mix moving forward, we would think that there is still some room to improve on our bad debt provisions as well.
