Yes. Bryan, thanks for the question. So first, we're pleased with the cash flow performance, a really solid start for the quarter. We're down a little bit year-over-year, but I remind you, last year was a terrific cash quarter, and this was really driven by receivables, which were impacted by the timing of Easter. In fact, we've looked at the first couple of days of the quarter and that collection period completely brought DSO back in line. So we're very comfortable with that.
So our cash profits really have been helped from the top line growth. And the net working capital execution, I was very pleased with what the team accomplished here in first quarter, particularly around inventory. So even with the Red Sea challenges and building up a little safety stock in certain areas, great execution on inventory. We saw the inventory days improve, DSO is strictly timing.
In regards to your question on capex, we had said previously that we expect capex as a percent of sales to be lower than last year. And it's really driven by Tide and Oxy kind of coming online and that investment dollar is dropping off. If we look at our leverage, the strong cash flow and execution has allowed us to bring our leverage using the S&P methodology down to 1.8 times, so an improvement from year end.
And to your point, we did pay back a bond here in first quarter of $500 million, and we did that with CP and two reasons. One, we had very good strong cash flow; and two, at some point, we expect interest rates will come down, though that appears to be sliding further out to the right, and that will help us keep our fixed floating back in balance.
So again, as we look at cash flow, strong performance and as we think about that, it kind of goes back into the capital allocation, and I think you've seen that manifest ourselves in our strategy, that capital allocation hasn't changed, invest in the business, and you're going to see capex go up and down, we're investing in advertising. Return to shareholders, we had a dividend increase, and you saw our share buyback in the quarter and then M&A, where we look at options to improve our overall portfolio.
