So in second quarter of last year, you will recall us stating that we were going to hire, I think it was 400 or 500 people, which we started with and then continue. This is in our Engine Products business. And by the end of the year, we have recruited some 950 net additional people. I think starting early as we did and providing the base level of training, clearly, you can see it pay dividends. And you are looking at our engine margins today, which have shown, I will say, a good outcome in the light of us taking on some of that pain last year. We continue to recruit in Engine Products in the first quarter of this year, and now I'm going to say about another 250 heads, but again it is an approximate number. Wheels, as you know, we already started recruiting even before engine, and that has continued. And as I mentioned earlier in my remarks, we do see the start of some improvements in the commercial truck build in the second quarter as a precursor to a stronger second half in that business and a robust 2023. So again, there is a willingness to recruit the increasing headcount in that business as well. I think the relative surprise to us was the decision that we made mid-Q1 to commence hiring in our fastener business. And that is a little bit ahead of what we thought, because of the demand outlook that we see again starting in Q2 and the balance of the year. So those are the three businesses that are recruiting, albeit better - I will say there could be passes, about 130 heads give or take and so a modest step but an important step, again, preparing the ground as we did to prepare the ground for our engine business a few months ago. The only business so far that we have not taken any recruitment steps on is our structures business as we burn off in the first half of this year some of the overhang, particularly on the titanium and aluminum bulkheads for the F-35 program, but have a view that mid of the second half of the year, so let's call it, end of Q3 or Q4. And obviously, that will be finessed as we get closer to the time, then we expect to commence hiring. And some of that is also tied up in the locking down of the scale of the additional orders for titanium, which we expect to talk to you about in August. So again, in summary, three areas of recruitment and an expectation with stronger sales of our normal structural products, the resumption of the 787 in the second half of production and some improvement in our F-35 outlook plus the titanium should enable us to consider recruitment in the second half. Ken, if you want to just touch on inventory.
