Sure. I mean, we talk a little bit about the locomotives, first. And again we took out 250 locomotives last year as we launch the TOP21 strategic plan and mainly those were on the sideline, but they were with a lot of other locomotives that we had on the sideline. We knew that every quarter throughout this year, we were probably going to see, we were going to convince ourselves that we were going to have more and more surplus locomotives. So rather than leak it out over time, we really held hands as an organization and said, look, we have got very good progress here on liberating assets in the field. Where can we be in a post-PSR world with regard to locomotive needs? And there were several iterations, I think, the PSR experts that we have in-house, really pushed the envelope and said, look, we know where we can get to. So, we had a 1,000 when we started the year on the sideline, the numbers initially started with 400, maybe 450, the team iterated several times and ultimately got back to a number of 703, where we said that is absolutely doable, even if we go back to 2018 volume levels, we can still manage with the remaining fleet. So we decided, rather than just leak this out over time to take a look at it, it was clearly a significant portion of the -- of that particular asset base. So we decided the right thing to do, the appropriate thing to do is actually pull it out of group accounting and write it off. The benefit of doing that, first off is, we get the organization focused on removing assets and I think that’s a very important thing for any company when you have surplus assets is to eradicate them, because assets attract cost. You got yard congestion in our case. You have got network congestion by parking all these excess locomotives, let’s commit to get rid of them quickly, and then they will attract less cost, less maintenance and less attention and less property tax whatever you can assign to it will end up being savings. So it’s healthier just to get to recognize what surplus upfront and move as quick as possible to remove them from the company’s properties. And then by removing them from group accounting, you also now have taken that $385 million asset and you avoid depreciating it over many years and absorbing it into your remaining assets, it seems like it’s a very unusual form of accounting that’s relatively unique to our industry, where you have group accounting attaching excess book value from discarded assets to remaining assets and depreciating further over time. So we avoid doing that, we get rid of it, we get depreciation benefit in the future. So that’s really how this came about.
