Yeah, I'll start and then Ed will give us some more color on this. Of course, you know, when we give guidance, we do it based on the best available information we have at the time. Obviously, we don't like to see, the revenue decline and you never like to be in a position of taking down the guidance for one of your portfolios. We do believe that, you know, our delivery business is critical for major enterprises to operate on the Internet. That said, delivery is a very competitive environment And we are subject to overall traffic levels on the internet, which we now believe will be in a lower state than we had thought before. And you know, this is typical. We've been doing this as the market leader now for 25 years, and there's times, when traffic accelerates more than you might have thought and times when it doesn't. And I think we're in sort of the latter mode right now. Now we do believe the business will get back to par. I can't tell you exactly when that will be. It's important for us to do that. I should add though, it's not our top priority. We are not out there doing whatever price it takes to go grab all the business. In fact, I think we've been pretty clear that's not the case. There's traffic that we are not taking because we don't feel that it's profitable or really strategic for us. Our primary goal is using delivery for very strong cash flow that we can invest in security and compute, which we think are much more lucrative markets in the long run, offering much more growth. And also we use it with our customers to introduce, for example compute. The [big-bit] (ph) customers, big media, gaming, are big prospects in compute. And the largest customers there are over $1 billion in third-party cloud spend, typical large media customer, hundreds of millions. And we want to get a share of that business which is much more profitable and ultimately much larger than delivery. So that is our focus here. Obviously we want to get back to PAR. We don't like to see a declining business but it's a bigger picture. And of course we are competing with a lot of companies that are very desperate just to get a little bit more growth in delivery, and even if they are doing it at a very unprofitable level, and that makes it more challenging. And Ed, maybe you want to talk a little bit more on the details of the guidance and the confidence?
