So Alex, I'm sure you can appreciate that's been a fundamental focus of our risk and our commercial team for the most part of the last 10 months to 11 months, and the overarching approach that we've taken has been to make sure that whatever actions we're taking are logical, they're reasonable, they're defensible, and ultimately documented because so much of what we're trying to manage through here is not explicitly guided for from a regulatory accounting, et cetera, perspective. So we in terms of the CARES Act, and the specific provisions that it provides for in our case, TDR relief from an accounting and regulatory perspective, but as well the spirit and intention of the CARES Act to provide support to help good customers that didn't have anything to do with obviously, a pandemic impacting them as negatively as it has. So we've worked as an organization to develop an addendum to our credit policies that we've called our COVID addendum to basically manage through and guide us through this process. And as part of that, Alex, one of the things by definition, if we are dealing with and helping customers effectively bridge to the end of the pandemic through relief and modifications, we’ve elected to call those loans special mention by definition, so we are watching carefully. We also want to make sure it's as transparent as possible for all of our constituencies; our investors, our regulators, our auditors, and as well the teams inside the bank that are working there, these loans. So, to your question, Alex, we have individually analyzed each of these credits, and ultimately through the policy that we develop, but the core conclusion was focused on their sustainability to get beyond the pandemic and to return to normal operations and in a post COVID world. So, that's the fundamental approach that we've taken that we are dealing with our COVID addendum, Incorporated, as I said, our best logical, reasonable approach, defensible, whatever regulatory guidance was out there. But ultimately, it's a policy that we developed to support this question in this issue. And, as Justin talked about, our CECL loss drivers, were in terms of our model, we're signaling stronger employment numbers, and we, as a result, worked in terms of our qualitative factors and the underlying risk that's out there in continues to be out in the economy and making sure that those were appropriately adjusted. And then in the fourth quarter, we identified those lists as part of this COVID bucket of loans that we believe had the highest loss flow risk and segregated them and took appropriate action relative to provision expense. So, Justin, I'll stop there, and you can help Alex with more specifics.
