So, let me tackle the strategic part and then Kirt can address the DTA methodology and issues. On the planning process, like every year, we do really divide two items, what we call the beta factors and the alpha factors. The beta are clearly driven by rate effect forecasts, which are provided by our economists, but also with a look into consensus. So, when we come out with views on how rates will develop in the next 12 to 36 months, we take market view in consideration, so -- to neutralize any subjectivity factor. We look at volumes in the stock markets, in different asset classes category. We look at GDP growth as an indicator for wealth creation, which may translate into monetization and also of wealth and, therefore, net new money. So, we look at different factors that are, let's call it, as I mentioned before, beta factors that will drive our business. Then the alpha factors are mandate penetration, market share and repricing of services, and new product development and entering in a new market and so on. So when we look at the deviation between six rate hikes by the Fed, that's what we had in our plan at the end of the year, which is not necessarily a year-on-year comparison. It's a deviation versus internal plans, and that's clearly a headwind that we are facing. In terms of cost, I already answered the question. For the next 18 months, we are focused on executing CHF2.1 billion of net savings. Despite all the challenges that we are facing, I think this is the best way, really, to create value for shareholders without compromising on quality of services to clients; without compromising on control functions; and without compromising, most importantly as well, I would say, on our ability to invest in the future. Because, clearly, we are in an industry that is still facing a lot of challenges coming from the past and today's environment. But we are also in an industry that has to compete with the future and with people who have more agile situations to compete and, therefore, we cannot stop investing. That would be very dangerous for the franchise. So, really, balancing growth and cost savings will be, regardless of market conditions, a priority for us.
