Yes. Thanks again for that question. Again, I take us back to what are we trying to achieve over the long-term, we're playing the long game here. Well before the pandemic, we had a vision to consolidate our head office footprint and the 23 locations that we have scattered across the Greater Toronto Area where a significant amount of our head office team is located into a modern purpose built headquarters, and it's called CIBC Square. It exemplifies the future of work. And what I mean by that is, it's flexible agile space, collaborative space, modern space, it reinforces employee wellness and convenience and we'll happy to highlight more of that into the future as we start moving in there, and it's equipped with the most advanced ventilation systems and technology. So now with the pandemic, it's allowed us to accelerate our consolidation plan, which is the result of some of the accounting that we undertook this quarter. As we move into a more normal environment, I got three points to highlight here. One is our team is going to return to the office including CIBC Square into our other locations across Canada and the U.S. We're going to do this with safety in mind, health in mind, and we're going to do in a very staged fashion because keeping our team healthy and well and engaged, is the most important thing to us. Some of our team members are going to work remotely, work permanently. We've had great success with our contact center team working from home. They're engaged, they're productive, they're speaking to our clients and making their experience much better. And the other thing I'll say is this. I think it's important to recognize that many of our CIBC team members have continued to serve our clients in the workplace throughout the pandemic. That includes in our banking centers, in our currency operations, our technology operations and it's really been a team effort. I mean, many of us have worked remotely, some of us have had to go to the workplace each and every day. I admire them for their courage and what we've done is tried to keep them healthy, and safe and well productive, while engaged with our clients. Now, the accounting of what happens with the real estate, Hratch, let me hand it off to you. Not -- to just want you to talk about accounting, but it's part of the question that was asked.
