Yes, sure. So obviously, you're going to put in a variable OpEx assumption depending on how you're flowing revenue through the year, roughly, let's call it, 8% to 10%, and then if you're -- I'm not going to give quarterly OpEx guidance, but I will give a little guidance on how we're thinking about the cadence throughout the year because there are some differences there, too. As you mentioned, there are a lot of things that are happening in, so as we think about moving into the third quarter, we are going to be a little bit more weighted on investments in 3Q. Some of that is due to timing of expenses associated with the Columbus shutdown, which are not technically qualified restructuring expenses, and then there's also a heavier investment lift in 3Q tied to some of the efforts around advertising and the solutions growth. Q4, if you move from Q3 to Q4, what I would tell you to think about is you'll have obviously a step-up in variable expense, will offset a good chunk of that sequentially based on investments that don't repeat in the fourth quarter, and we have a bigger productivity target in 4Q, so if I step back broadly and think about expectations on OpEx on a year-over-year basis for the full year, to your point, there are a lot of moving pieces. The way that I would try to simplify the explanation, the two tallest candle sticks are merit, which is about half of the increase and strategic investments, which is the other half. To your point, a lot of moving pieces on G&A, on acquisitions. We're covering those with productivity, so to simplify the story, the things that emerge are merit and strategic investments that make up the year-over-year lift.
