Yeah, absolutely. Nathan, there's kind of a big difference in our minds between favorable results in one year and the non-recurring type performance, if you will. So, we think about each year, we reset at corporate, and I'll go through a couple of the big buckets. We had decent amount of favorability on the environmental line in 2016. And basically, the way it works for us with environmental, we start every year with an understanding of the sites that we're involved in, the activities we need to remediate, and we project the cost based on what we know entering the year. And then, the second we start the year, we work aggressively to reduce those costs to drive more efficiency at the site locations and then to drive insurance recoveries. So in 2016, we had a very strong performance year which gave us $6 million of favorability. As we reach that 2017, based on what we know from the sites we're going at, we would kind of reset that environmental expense and we would right away start up trying to do better than that from an execution performance perspective. But with that kind of number, there's no guarantees as to what could happen with environmental expenses. It's not all within our control. So, that's just to give you a flavor for how some of these non-functional corp items work. Similar story with interest and investments: We had about $5 million of favorability in 2016. Don't want to call the markets in 2017 and expect that level of performance, so we do re-baseline those assumptions going from 2016 to 2017. As you mentioned, we had $5 million of compensation reset and that's just a reflection of obviously what – where we ended up in 2016 and resetting back to budget for 2017. And then lastly, there's about $5 million of favorability generally tied to our workers' compensation performance. And again, this is another one of those situations where every year we come in with an expectation of what the cost will be and we work hard to try to reduce those costs through good solid management of cases and good safety protocols within our operational environments, and we had a good year of execution in 2016, but we just can't expect that to repeat again in 2017. And just like environmental, some of those costs can go up from year-to-year. So, that's just to give you a little flavor of the four or five major buckets that we manage in corporate year-to-year. But I would say the 45 is absolutely the right starting point run rate, and we're going to go just like we did in 2016 and try to see if we can execute as best we can to bring that down over the course of the year.
