Yes, no problem. And I think it's a good question, Suraj. Thanks for asking it. So let me kind of break it into two because one element of it is the contracts themselves and the nature of them. So these contracts are multiyear, and they don't all start and end at the same time, obviously, right? So there's always an overlap and we have some contracts that we signed last year that are good for 3 to 5 years and some contracts that are coming to expiration. But on average, it's been kind of that rolling 70% that's under contract. These contracts obviously define terms, commercial terms and whatnot to kind of help both -- protect both companies but also kind of define the rules of engagement, if you will. So that's -- that a lot of things are covered in that. We obviously want to make sure that we protect ourselves, right, in terms of the terms of the contract as it relates to some commercial terms, price and whatnot. But there are elements, I think what you're alluding to is the operational element of it. Yes, of course, there are some elements that defines what forecast on inventory and whatnot you do, and those obviously vary. But generally speaking, I think what's implied in your question is also maybe a little bit of a variability in the forecast. These contracts, nor most contracts that exist anywhere in any industry really don't define a very specific multiyear forecast on take-or-pay. Our customers obviously do not have certainty in the demand of the products, nor would they want to put themselves in a position that they have to very clearly define what those products would be. Now what we do, just to make sure that we're running our operations efficiently, we have requirements from our customers and our customers usually give it to us anyway just to make sure that we are prepared. Visibility, I would say, within 12 months. They give us a 12-month forecast in advance. As you kind of think about months 6 to 12, that forecast can have a little bit more variability to it, that's just by nature. And as you get closer, it's a little bit tighter. That 1- to 3-month forecast, I would say, is the tightest because that's where manufacturing plans are in place and where production plans are in place. So there's little variability there. And by little, I mean, usually, there's not a drastic change. I mean, there's that few million dollar give or take that I talked about. But generally speaking, we have good visibility to our demand. And the $700 million backlog that we keep talking about is I think about it as order books, as an order book. That -- those are the orders that we have on our books that specifically say what customer, what SKU, what month of shipment, and that gives us that good visibility a few quarters ahead.
