Sure. Thanks for the question, Brian. So yes, if I could just maybe kind of go back through some of the items that I believe caused the shortfall in Q4 and then maybe talk a little bit about '24. We finished Q3, I believe our accounts receivable balance was about $2.16 billion. We expected that to come down in Q4, particularly as we claw back some of the built up AR from our Cerner conversions. As we went throughout the quarter, we -- although we clawed back maybe 1/3 of that, we did not claw back all of that. We had some additional buildup in AR, particularly around some of the in-sourced physicians as well as timing of some commercial payments. The holidays fell on a weekday, the last week of December, and we didn't really have complete insight into how some of the commercial payers may pay at the end of the year. So really, we look at that as just more of a timing issue. -- then the Mississippi program came through, which the cash of that wasn't paid in December, so added to our AR. And at the end of the day, the accounts receivable balance increase instead of decreasing as we expected, had increased at the end of the year. So that was all in, call it, roughly $130 million headwind in cash flow in the fourth quarter. Then we talked about we did a refinancing in the fourth quarter. We had to accelerate in the repayment of the bonds, accelerate some of the interest payments that otherwise would have been paid in '24. So that's clearly a timing issue because now that interest is paid and we will not have that payment in '24. We also settled a legal case, the Mason case, which was about $30 million in the fourth quarter, made that payment, which was not anticipated. We just did not know the timing of when that payment was made. We had it accrued at the end of the quarter, but did not have the timing of when that payment would be made. So those are kind of led to and are, again, primarily some timing related matters. As we go into the '24, a couple of things, I'll just reiterate around the 163J interest deductibility. That has passed the house. It is in the Senate, although we don't know when or if the Senate will pass that rollback. So we've not anticipated, we've not put that in our guidance this year as well as the tax refund, which we still feel very comfortable that we're going to get, but we were wrong. I was wrong about anticipating the timing of that last year. So I'm not going to predict the timing of our government approving that this year. So if either of those come through, they would be positive. Our current cash tax estimate is $150 million to $200 million, and that could be reduced if either of those items come through.
