Thank you, Humberto. Good morning, everyone. Second quarter 2021 revenues were $449 million, a 285.7% increase when compared to the same period of last year, mainly due to the halting of precipitation during most of the second quarter of 2020, as well as an increased baggage cement shipment. However, even if we compare this quarter revenues to those from second quarter of 2019, there is still significant increase of 37%. Gross profit increased substantially this quarter compared to the second quarter of 2020, mainly due to the fact that it was close to zero during same year because of the whole variation and subsequent effects in gross profit. There was no dilution of fixed costs. Consolidated EBITDA was $90 million in the second quarter of 2021, representing a significant increase when compared to the second quarter of 2018, when EBITDA was negative, for the above mentioned reasons. We expect an important increase in EBITDA for the rest of the year. During the six months of 2021 revenues increase 119% and gross profit increase 116% when compared to the same period of 2020 mainly due to the increase in sales, as well as the above mentioned halting operations from mid March to mid May. Turning to operating expenses, administrative expenses for the second quarter increased 41.7% compared to the second quarter of 2020 in line with increased sales, but mainly due to the substantial reduction in expenses during the lockdown period in 2020. As well as an increase in workers profit share as a result of improved results. Selling expenses in the second quarter increased 71.1% compared to the second quarter of last year mainly due to the above mentioned decrease in expenses during 2020 and an increase profit share. During the six months of 2021, administrative expenses increased 28% and selling expenses increased 29% when compared to the same period last year, mainly due to increases in sales as well, a savings implemented during the six months of 2020, offset the negative effects of the housing operations. Moving on to the different segments, cement, concrete and precast sales increased 296.5% during the second quarter of 2021 compared to the same period of 2020 mainly due to the halt in operations during the second quarter of 2020 as well as an increased sales of baggage cement. Gross margins increased 26.4 percentage points in the second quarter of this year, compared to the same period of last year mainly due to sustained fixed costs, with virtually no selling during the second quarter of 2020. During the six months of 2020 sales of cement, concrete and precast increase 120.1% and gross margin improved 5.1 percentage points, mainly due to increased sales and halt in commercialization during the second quarter of --. Sales of cement increased 261% in the second quarter of 2021 compared to the second quarter 2020 mainly due to the halt in commercialization during the same period of last year, as well as an increase in shipments of baggage cement as demand to north continue booming during this quarter. Gross margin increased 19.2 percentage points, mainly due to the negative effect on costs during the halt in operation in the second quarter of 2020. During the six months of 2021 sales of cement increased 121.8% and gross margin improved 2.1 percentage points when compared to six months of 2020 mainly due to the halt in production and commercialization mentioned above. During the second quarter of 2021, concrete and pavers sales increased substantially since they were only $3.3 million in the second quarter of last year because of the complete halt in commercialization. Gross margin increased 273.5 percentage points mainly due to the significant costs that could not be reviewed it on last year. Similarly, sales of concrete and pavers for the six month increase132% and the gross margin increased 20.2 percentage points compared to the same period as of last year. During the second quarter of 2021, precast sales increased 347.4% compared to the second quarter of 2020, mainly due to halt in operations. However, if we compare precast sales to the first quarter of 2021, we can see that a positive upward trend continues since sales increased 33.3% quarter-on-quarter. Gross margin increased 94.8 percentage points mainly due to the negative margin during the second quarter of 2020 because of fixed costs without sales during that quarter. Similarly, during the six month precast sales increased 31.6% and gross margins increased 20 percentage points as compared to the same period of last year. Quicklime sales in the second quarter increased 20.6% compared to the second quarter of 2020 and gross margin decreased 7.7 percentage points compared to the second quarter of 2020 mainly due to the increased demand, but most of it from granulated quicklime which has a lower margin than ground quicklime. During the six months of 2021 sales increased 22% and gross margin increased 0.6 percentage points. During the second quarter of 2021 and the sixth month of 2021, construction supply sales increased 384.2% and 161.3% compared to the same period of last year primarily due to increase in sales from the halt in commercialization. Gross profit improved 12.4 percentage points in the second quarter of 2021 compared to the same period of last year, mainly due to low comparative basis, in six months 2021 the gross margin remained in line with the same period of last year. In terms of our debt, our debt to EBITDA ratio has come down to 1.9x. But the important issue is that we have to know that we have been able to recover low indebtedness level quickly after most trying times.
