Certainly. Okay. Yes, it does. The $1.37 includes all the expenditures that we have had at the operational side of our facilities in both Mexico and Peru. In total, we have spent a little bit less than $12 million in this past quarter for sanitary standards, et cetera. This includes -- let me explain what I mean. This money is just for purposes of maintaining proper working conditions with -- for our workforce. It does not include the donations that we're doing that are included in some -- in the administrative expenses for the company. And in the case of cash cost and production guidance, certainly -- for production, I mentioned already our forecast for the year, but I'm repeating it now. We're expecting to produce 997,100 tons of copper for 2020. Our production will be pretty much flat all the way to 2023. For 2021, we're expecting to produce 986,300 tons; 2018 -- 2022, 949 -- 950,000; 2023, where we will have the beginning impact of Pilares, Buenavista zinc and El Pilar, we're expecting to increase our production to 1,066,000 tons. For 2024, we're expecting to produce 1,104,000 tons, and this is basically the result of having Pilares, Buenavista zinc, El Pilar and a partial production of Tia Maria. In the case of cash cost for this year, I already mentioned that we are expecting an overall for the whole corporation cash cost before by-product credits of $1.37. In credit, we're expecting $0.60 per pound of copper. That give us $0.77 per pound for the year, slightly higher than what we're expecting now. As you know, cash cost is one of the most difficult things to predict because it has not only the cost impact on several supplies, such as fuel, power, et cetera, labor and -- but also the impact on price -- of prices on our by-products. I mentioned already -- I mentioned already silver price, an average silver price for the quarter of about $16.54 per ounce of silver. And as you know, now it's over $20. It's much higher than that even today. So it will vary, but that's our forecast at this point, $0.77 per ton. For the next few years, well we're assuming an increase in our cash cost due to the price deck that we're considering for the next years and certain ore grades variances that we have in different operations. Overall, we will have -- we're expecting a cash cost of about $0.93 for 2021, $0.96 for 2022, $0.88 for 2023 and $0.87 for 2024.
