Yes, so a couple things, Krish. The first is that you're right, we would expect results to improve over the course of the year. But it's important to think about the seasonality of that. We do think that the parts environment that we're in continues to be challenging. And we expect that to continue not only to Q1 but into Q2 as well. And many of the actions that we have taken internally around part redesigns. And even when we look at when more parts are going to becoming available, we believe that's more in the second half. So we would expect to see Q2 very similar to Q1, when we look at our outlook, just based on parts availability. Now as those parts become available, as I mentioned earlier, I think we have upside to our revenue levels, which is why we've said that we expect to be able to exit the year at this $400 million rate or better. And the second thing is, as this supply chain situation normalizes and we don't have these, I'll say premium costs where we're paying for higher priced parts on the open market, that's going to also have a significant improvement in gross margin, which allows us we think, to get to an X rate of $6 a share an on annualized exit rate of $6 a share. So we do think that the key to this is just parts availability and that there's a lot of pent-up earnings in the company. The question is timing. And our best view of that timing is its second half and exiting the year we should be performing at a much higher financial level. Now you're right about operating expense. Look, we think operating expenses are going to be up about 6%, year-on-year, if you look at all the pieces, most of that's inflationary, but you do have a little more cost from acquisitions we made during the year that have a full year next year. And because revenues are relatively flattish beginning of the year, if you just do the math, you'll see that the operating expense growth is probably a little bit higher than revenue. Having said that, we believe that even with that growth, that exit rate of over 400 million in revenue and $6 per share annualized contemplates that operating expense growth. So we don't think it makes sense to cut costs in this environment, it’s a supply constrained environment, we've continued to invest in our critical programs, in our people, we are seeing some inflationary pressures. We've taken some actions to combat that around efficiency and some reorganization that Steve's talked about. But fundamentally, we believe there's a lot of pent-up earnings in the model and it makes sense to continue to invest through this soft spot that's created by the part shortages.
