Thank you, Michael. Second quarter revenue was a record $448 million, an increase of 12% from prior year. This increase primarily reflects contribution from the Kosmos Cement Business, we acquired in March, and organic revenue improved 2%, reflecting increased Cement and Wallboard sales volume. Second quarter earnings per share from continuing operations were $2.16, an improvement of 20%. As we highlighted in the press release, the second quarter results included a onetime $0.14 per share tax benefit. This benefit related to regulations issued during the quarter to clarify the calculation of certain interest deduction limitations. Before we turn to the segment performance, I'd note that having completed the sale of our Oil and Gas Proppants business during September, the current and prior period financial results of that business have been presented separately as discontinued operations on the income statement and balance sheet. Let's look at our Heavy Material results for the quarter, highlighted on the next slide. The Heavy Materials sector includes our Cement, Concrete and Aggregates segments. Revenue in this sector increased 15%, driven primarily by the addition of the recently acquired Kosmos Cement business. Organic cement sales volume and prices improved 1% and 4%, respectively. Operating earnings also increased 15%, again, reflecting the addition of the Kosmos Cement Business. As we discussed last quarter, because of COVID-19, we delayed certain planned cement plant maintenance outages until our second quarter, which resulted in approximately $5 million of higher maintenance costs this quarter compared with the prior year period. Moving to the Light Materials sector on the next slide. Second quarter revenue in our Wallboard and Paper business was up 1%, as improved sales volume was partially offset by lower Wallboard prices. Quarterly operating earnings in this sector declined 1% to $48 million, again reflecting lower Wallboard sales prices, partially offset by increased volume. Looking now at our cash flow, which remains strong. During the first 6 months of the year, operating cash flow increased 94%, reflecting earnings growth, disciplined working capital management and the receipt of the majority of our IRS refund. Capital spending declined to $41 million, and we continue to expect capital spending in the range of $60 million to $70 million for fiscal 2021. Finally, a look at our capital structure. We continue to prioritize debt reduction as a primary use of cash at this time, and the preservation of financial flexibility in line with pandemic-related uncertainties. At September 30, 2020, our net debt-to-cap ratio was 48% and our net debt-to-EBITDA leverage ratio was 2x. Total liquidity at the end of the quarter was over $700 million, and we have no near-term debt maturities. Thank you for attending today's call. We'll now move to the question-and-answer session.
