Good Morning Aileen, this is Jim, let me take a shot at trying to kind of, let's say swallowing the ocean question from the standpoint there were so many moving parts in the quarter that it's kind of hard to put in a quick succinct answer, but let me start with some momentum around in anyway. If you just start with where we were at relative to inbounds from our customer base, which was obviously we're not just light vehicle, that we're across probably 10 different markets when you include agriculture, underground mining, whatever the case, but a pretty consistent theme back then would have been these most recently published releases or schedules are accurate. We have record demand, we're going to make every one of those vehicles by the end of the year. The semiconductor shortage is improving, and those type of things was basically the theme of how we were setting up the back half of the year, and it's not the customers vault that semiconductor issue became a bigger issue than maybe anyone expected and we buy obviously PCB boards and semiconductors ourselves so we understand it. But in big picture, we have contractual responsibilities across not, we don't have like 10 customers or 20 customers, we have hundreds of customers, and the big picture way of looking at it all those moving parts that I just said, most of them didn't come true. So when you think about our ability to be able to flex, it would be basically in many cases, customers were building products, especially in off-highway and commercial vehicle where there's a lot, a lot of lower volume, high complexity customers. They were building vehicles based on whatever their material they will be was of the day. So you can imagine the inefficiencies that drove really throughout late October throughout November, all the way into December. It was just a kind of survival thing in some of the circumstances we deal with, with an entirely different customer base than many people that you would typically cover. So that's the starting point to it, but we wish we could have had better line of sight to that, but we didn't. We just had to continue to work through the same, basically pandemic related issues there else did, it's just on steroids.
