Sure, Ken. Obviously, you know, Frost, you follow us for a long time, obviously very conservative. We continue to be concerned about what's going on in certain industries, commercial real estate, for example. And just given where we are and the expectation of what could still come whether that be variant, whether that be issues associated with office buildings and whether employees come back to work, whether that's related to hotels and lodging. I think we just felt like it was too early in the process to release reserves. Our modeling results in the commercial real estate category would actually have, we would have required if you will, from a modeling standpoint, that we have a lower reserve associated with them, but really in our evaluation, we created management overlays, just given the challenges that we potentially see out there in some of those COVID impacted industries. And so, I think Phil mentioned the COVID impacted industries there, they are still out there at 1.5 billion. We've got a reserve associated with them at 4.9. So I think part of it is just, we're not out of the woods and don't feel like we're out of the woods. And so now didn't really feel the need. And for certainly felt like we could substantiate the allowance that we've got on our books, and obviously, through the rest of the year, we'll continue to look at that, we didn't book a credit expense in the first quarter, given what we're seeing today. I don't expect to have a provision to be quite honest with you assuming the same sort of credit metrics that we saw on the first quarter. But again, a lot of it'll just depends on what our credit quality people are doing, our special assets people are doing and what they're seeing in the marketplace. But at this point, given where what we were seeing and what we were feeling, we felt like keeping our reserve, basically, flat is the way I looked at it to go from $175 million to $177 million basically solid I thought was a good place for us to be. You did note that we only had $2 million in net charge-offs during the quarter. We were helped by a pretty strong recovery. We actually had recoveries of $4 million. So again, I think we're comfortable with where we're at and certainly are looking towards the rest of the year and hoping that things continue to improve. And as we go through each of the quarters, we'll continue to evaluate our allowance and react accordingly.
