Yes, right now, I would say that the aftermarket type products are probably in the mid-single digit percentage, now that's due to the total inbox. So inbox basically dominates. But that is changing rapidly. We are seeing a lot more aftermarket design wins and the revenues are growing very quickly in that space. As far as the OEMs deciding to move the charger out of the box, I think it really varies a lot from OEM to OEM. For example, the OEMs in China are really using faster charging as a major selling point, and so they like to put it in box because [indiscernible] has a significantly higher power and capability. But it's very possible that in the long run some of them, some of the OEMs may choose to not sell the charger with the box. In this case, the consumer has to either have a charger from their past division phone or they have to buy a new one. In the short term they have to buy a new one, because the older ones that are not the USB PD compatible, or they don't have the fast-charging, they can't charge fast. So we are optimistic that even if they go out of box, the attach rates will be reasonably good. And so, there are pluses and minuses. A number of units that will come down, obviously, if you go out of the box. On the other hand, we will have exposure to the entire product line. For example, right now our attach rate is very small, because they are only on the high end, the faster chargers on the high-end phones. If the consumer has to make the decision, even the consumer who buys a lower end phone can't buy faster chargers or a higher power chargers for multiple reasons. Most of the lower end phones can't handle faster charging, they just don't come with it in box because of cost reasons. So we think that attachment rates could be significant, obviously not 100% but it is in the 10s of percent range, maybe 30%, 40% but it applies to the entire product line, not just the high end. So that's the plus of it. The minus of course is that the overall unit volume is lower. So it's not clear to us exactly how it's going to impact us, because these higher power chargers are higher ASP and also some of them are multi-port, which means you get 2 times or 3 times the ASP. So it's -- I think that there are pluses and minuses, but this is something we've known for a long time. We have talked about it in the past. And so this is not a surprise to us and it's not clear how many will actually follow that path.
