Yes. So first of all, if I remember, Walter, I had a few fairly aggressive questions from you several quarters ago around our aggregate leverage. And as I pointed out, it peaked at a net leverage target of 4.6, which was, as you pointed out on that call, substantially above the 2.5 to 3.5 range that we had laid out. We have been able to reduce that leverage to 3.17, substantially below the high end of that range. And that number will come down even further in the next quarter as it is, as Tad pointed out, an LTM tax. We are going to look at our aggregate balance sheet and try to optimize whether it be through incremental high yield, whether it be through securitization or through asset sales. We have many levers to pull. We have been very transparent around the reduction in payments from T-Mobile. They are going down. They will go down in June. However, we are achieving substantial cost savings ahead of what we laid out. And again, I know -- I think it was last quarter, you had great doubts on our call about our ability to do that. And I think our improvement in EBITDA shows clearly our ability to reduce those costs, both SG&A and COGS substantially. So I think it will be the combination of cost reductions and revenue growth. As the incremental wavelength business grows at a more normalized rate with very high contribution margins, our aggregate EBITDA will begin to grow. As I laid out on the last call, we did $352 million in EBITDA in '23, up from $233 million in '22. While we're not giving exact guidance, it will be similar in '24. But in '25, the impact of wavelengths, IPV4 monetization and data center monetization, coupled with growth in the core IP business should grow our EBITDA and expand margins. As I said, it's a top line 5% to 7% growing business with a 100% or a 100 basis point a year margin expansion. I'm also going to clarify a question that I didn't answer for Frank, which is T-Mobile's utilization. And that's 2 parts. One, the commercial services are typically connectivity services and [ Colo ]. They're getting out of our facilities. They are stopping using us for backhaul. In many cases, we're buying it and reselling it to them. That's part of why off-net declined. They are very far along in that exit. The revenues declined sequentially at about $5 million. On the transit services, it was always meant to be a subsidy payment to Cogent. They are using a couple percent of the transit that we are providing them. They could use it all. It would be fine with us. It's all provision. But I'm not sure there's a huge incremental opportunity with T-Mobile. Hopefully...
