Yes, Katie, thank you. Yes. As everybody knows, it was a crazy year to try and track customer trends. And as Dave said, with the bulk of our hit when the pandemic happened, we sort of got to the trough across all markets in the second quarter, somewhere around April, May. But if I kind of look at the fourth quarter and project forward, when we look at retail inserts, as Dave said, is the one that got most heavily impacted. I'd say that, by the way, since we hit that trough in the second quarter, we had seen incremental gains in all areas of our business. Retail inserts, to start with, which was the hardest hit, was off about 42% in Q4, which is fairly in line with overall retail inserts. I think we'll continue to sort of see some ebbs and flows on this because retail inserts will continue to be very sensitive to how we come out of this pandemic. And we also look as people had cut back on how they will readjust their future trends. And so more to come on that. Catalog, which was the next one that was most affected, is off double-digit, in the teens. So call it about somewhere in the mid 15 percentage, which is in line with the industry. Again, we saw incremental improvements through the year. And I think that as the pandemic kind of runs its course here, we'll see that continue to settle down. The third one is publications. Again, I think a lot of people got hit with number of pages in terms of advertising pages or even some titles going out of business and circulation trends. But because of market segment share wins, in fourth quarter, we were only off about 4% versus an industry average of about 15%. And so again, we've got a great platform for publishers and we've been able to really continue to perform for them. When I look at direct mail, that's a great story. We're actually in the fourth quarter up a couple of percent with -- I'd say the USPS DM estimate for fourth quarter was off about 4%. So we're actually up 2%. And this is important. There is definitely some tailwind from political mailings and things like that. But the way that we're approaching direct mail is really about more of a value added. So trying to go from non-personalized, non-data-intensive and driven to data-driven as well. And so when we look at direct mail, it continues to be a place that we think will grow. And then finally, when I look at packaging, we were up as well, about 3% in the fourth quarter, which sort of follows trends that have happened in packaging. And also the other areas of growth have been in-store. And so still a lot of challenges in seeing the future and very hard to predict. But again, we expect to see continued incremental improvements.
