Thank you. Maybe if I can use a couple of minutes to explain this program in detail, I think it will be useful. As you said, we are focusing on the costs, not only in the short-term, in the long-term as well. So, this program has some short-term quick wins approach, which we want to benefit in 2021. However, in the meantime, we want to focus on long-term structural changes where we can benefit from the upside in the long term -- meaning in the next couple of few couple of years. So, before starting this program, what we have done, we said that let's get our cost structure. And as you know, in telecom, there are certain costs that you can address, and certain others that you cannot address because it's out of your control. It's coming from the from the market dynamics, it's coming from other dynamics. So, when we look at our cost structure, we found that positively more than half of the costs in our portfolio, which is 56% to be precise, can be addressable. So, that's a good starting point. And there are these other companies that we look at, we look at the currency dynamics in our cost base. Again, we found out that overall cost base, our costs based on foreign denominated currency, which is [indiscernible] U.S. or euro is only around 10%. So 90% of the cost overall is denominated in local currencies. That's also a good starting point for us. So, what we are trying to target here this is not only a one-year program, this is a long-term program, which will be derived from -- of course, in the country level, it could not be driven from HP [ph] but that is still driven by the business owners in the countries. So, we have multiple initiatives, hundreds of initiatives in each and every country. Some of them are short-term, some of them are long-term. For the long-term, we have the investors probably this year, and get the benefits in the coming years. But all the low, we are very optimistic that we can start to get upside from this cost program in the coming quarters in order to incentivize the upper management as well. We also incorporate a certain target coming from this project in the short term incentives or the local senior management teams. So that's why we are quite positive about the program. It has made it early to quantify the benefits for this year, but I think in the coming quarters, we will be in a better position to give you more visibility about the outcome and the plans in this program.
