Yes. Thanks, Hamzah. So when we look at the third quarter, despite having a record EBITDA and revenue, we underperformed on OR, so we had erosion of 190 basis points versus a lot of our peers that had improvements in their OR. Now I mentioned in the opening remarks that we, as a carrier, have a higher dependency on purchased transportation. So these are -- we call them internally highway subservice miles, where last year in Q3, we had roughly 26% of our miles were highway subservice. And we continued a long-term strategy to in-source highway subservice, which has fared well for us in the past, but it was a tough time to do this in a quarter where you have obviously labor shortages and equipment shortages, which put pressure on our linehaul network, and that caused our network to become less efficient, and the network flow was not as efficient as we would have liked it to be, which effectively increases the cost of being able to fulfill the service we expect. And it also reduced the amount of capacity we have in the network. So, when you combine these things, we -- this is kind of where we saw that OR erosion. Now, we have an action plan, as I mentioned in the opening remarks. It's a 5-point action plan to address this issue. Number one, it's around the strategic embargoes, where for a selective number of sites, we meter the amount of freight that we are getting from our customers in those sites to improve the network flow. And we've seen great results so far; great feedback from the field. I’ve been spending a lot of time in our terminals over the last month, and it’s good to see the impact that this is having in our operation. The second area is around yield. Although we had record yield in the quarter, which is a 6% year-over-year improvement, and it accelerated from 4.5% in Q2, it still needed to be higher. We didn't move as quickly as we should have on raising prices on our customers, and we are taking action on this. So, we already are seeing a very nice improvement in October of our yield performance. And the actions we took there, one was on contract renewals. We've seen a higher percentage on yield improvement there. We are charging our customers accessorials when they detain our trailers, so we can get more of that equipment back into our fleet. We are also charging them whenever they are shipping something that is irregular or long or doesn't fit our network and doesn't allow us to optimize our trailers as well. And then we pulled our general rate increase from early next year -- usually we do it in Q1 -- to this Monday to also capitalize on the local accounts, getting more yield improvement there. Now, the third area has really 3 components to it, which is adding capacity to our network. So when we think about capacity, it's about drivers, it's about equipment and it's about physical terminals, so doors and actual -- the physical space where we move the goods. On the driver side, we have a competitive edge with our driver school, and we're investing more into these driver schools where, this year, we're going to graduate roughly double the number of drivers we had done in 2019. And we are looking to further double that number going into 2022. So that's going to be a solution for us to add more drivers to our driver ranks and help counter some of the driver shortages we're seeing in the industry. On the equipment side, our biggest need is around trailers. So when you have inefficiency in your network, effectively, you need more trailer space to be able to -- and when you in-source also purchased transportation, you need more trailers. And we – I was in our Searcy, Arkansas facility last week, and we're investing more CapEx, adding more production lines to be able to double the production of trailers going into 2022, as well. And the last aspect of the action plan, which is more of a medium- to long-term growth strategy, is focused on adding doors in the markets where we are seeing higher demand from our customers. These are typically the key metro markets, and then investing in the physical footprint of adding terminals and expanding terminals from a doors perspective, and we're adding roughly 6% more doors than what we have today in the network over the next 12 to 24 months, so we can handle more of our customers' freight and capitalize on the hot market we're seeing in LTL. But that hopefully gives you a good color on what happened one in Q3, the action plans we're taking to course-correct that moving forward and pivoting toward the growth strategy, as well.
