Well, this is Mike. I'll just talk in terms of general. First off, the reason we wanted to put some comments in the outlook regarding, obviously 2021 is continuing to be impacted. It's been a really, really tough year, but it's also been a year that - accelerated changes that allowed us to - and forced us in some ways, but allowed us to get our cost structure in a much more variable basis, and that will continue to benefit us in fiscal year 2022. But the things we're really counting on for fiscal year 2022 to get us to EBITDA positive. We're at this point very confident about it, is the vaccines and their impact on getting students back on campus, opening up sporting events, getting fans in the seats during game days and that type of things. As you can see from our results that, we've kind of held our own on the courseware side, where we've been hit very, very hard this past year on general merchandise. So, general merchandise turning around not just from the change in the on-campus population, but also everything that that brings with it, people coming et cetera. And increases in online sales as well for the emblematic clothing, and that's where Fanatics and Lids come into, is making this change now should really help us in concert with moving to our own e-commerce system, help to improve our e-commerce sales quite a bit. Because those patterns of buying are permanently changed, as we all know, and they're headed towards ever-increasing reliance on e-commerce or digital sales. So, the timing of the partnership really, I think kind of been better. We have the time now to implement it and get it up and running for many schools in the summer and then the rest of the schools in the fall. So we're doing that. It's important to understand we’re doing that rollout in concert with - the rollout of our new e-commerce system as well so that we have a. user experience that's fairly seamless. In addition to general merchandise, we're counting on and very confident about the growth of bartleby and its contribution financially. It's starting to become much more significant on a relative basis. We have a new leader in place that's going to help us get some place to write that, et cetera. But we have substantial momentum even in the spring over the fall in terms of the traffic and the subscribers. So we don't expect learning to go back to completely in-person. The virtual models and the hybrid models are going to continue and students are going to continue to want to take advantage of bartleby's anytime anywhere capabilities to help them with their homework and writing needs and the other needs that we're going to address to the evolution of the product that's rapidly going on. And obviously, as Jon talked about, First Day and First Day Complete and the momentum we have behind those is another important contributor to margin. Our focus is really on margin and cash flow. The Fanatics deal will result in more of an agency relationship in terms of us being commissioned on the sales. So we'll have to explain that as we get better visibility into the quarters when that starts to happen, but we expect growth in margin and cash flow as a result of that partnership. Bartleby and the new courseware delivery models we're putting in place, a lot of it is dependent upon. There is still some uncertainty about COVID protocols and what's going to happen in the fall. But right now we're - from what we're hearing and what we're seeing with the vaccines even on the variance we're very optimistic that the fall '21 is going to be, I won't say back to normal, which is what we've said, but very, very strong compared to what we saw this past fall. I’ll now ask either Jon or Lisa can - or Tom can hop in on that answer.
