Thanks, Joe. For the second quarter of 2019, net income attributable to Valero's stockholders was $612 million or $1.47 per share compared to $845 million or $1.96 per share in the second quarter of 2018. Second quarter 2019 adjusted net income attributable to Valero's stockholders was $629 million or $1.51 per share compared to $928 million or $2.15 per share for the second quarter of 2018. For reconciliations of actual to adjusted amounts, please refer to the financial tables that accompany this release. Operating income for the refining segment in the second quarter of 2019 was $1 billion compared to $1.4 billion for the second quarter of 2018. The decrease from the second quarter of 2018 was mainly attributed to significantly narrower medium and heavy sour crude oil differentials relative to Brent crude oil. Refining throughput volumes averaged 3 million barrels per day, which was 70,000 barrels per day higher than the second quarter of 2018. Throughput capacity utilization was 94% in the second quarter of 2019. Refining cash operating expenses for the second quarter of 2019 were $3.80 per barrel, in line with the second quarter of 2018. The ethanol segment generated $7 million of operating income in the second quarter of 2019 compared to $43 million in the second quarter of 2018. The decrease from the second quarter of 2018 was primarily due to higher corn prices. Ethanol production volumes averaged 4.5 million gallons per day in the second quarter of 2019, an increase of 531,000 gallons per day versus the second quarter of 2018, primarily due to added production from the three ethanol plants acquired in November 2018. The renewable diesel segment generated $77 million of operating income in the second quarter of 2019 compared to $30 million in the second quarter of 2018. Renewable diesel sales volumes averaged 769,000 gallons per day in the second quarter of 2019, an increase of 387,000 gallons per day versus the second quarter of 2018. The increase in operating income and sales volumes were primarily due to the expansion of the Diamond Green Diesel plant in the third quarter of 2018. For the second quarter of 2019, general and administrative expenses were $199 million and net interest expense was $112 million. Depreciation and amortization expense was $566 million and income tax expense was $160 million in the second quarter of 2019. The effective tax rate was 20%. With respect to our balance sheet at quarter end, total debt was $9.5 billion, and cash and cash equivalents were $2 billion. Valero's debt-to-capitalization ratio net of $2 billion in cash was 26%. At the end of June, we had $5.4 billion of available liquidity, excluding cash. With regard to investing activities, we made $740 million of capital investments in the second quarter of 2019, of which approximately $510 million was for sustaining the business, including costs for turnarounds, catalysts and regulatory compliance. Net cash provided by operating activities was $1.5 billion in the second quarter. Excluding the impact from the change in working capital during the quarter, adjusted net cash provided by operating activities was $1.2 billion. Moving to financing activities. We returned $588 million to our stockholders in the second quarter. $376 million was paid as dividends with the balance used to purchase 2.6 million shares of Valero common stock. This brings our year-to-date return to stockholders to $1 billion and the total payout ratio to 50% of adjusted net cash provided by operating activities. As of June 30, we had approximately $2 billion of share repurchase authorization remaining. We continue to expect annual capital investments for both 2019 and 2020 to be approximately $2.5 billion with approximately 60% allocating to sustaining the business and approximately 40% to growth. The $2.5 billion includes expenditures for turnarounds, catalysts and joint venture investments. For modeling our third quarter operations, we expect refining throughput volumes to fall within the following ranges: U.S. Gulf Coast at 1.71 million to 1.76 million barrels per day; U.S. Mid-Continent at 440,000 to 460,000 barrels per day; U.S. West Coast at 255,000 to 275,000 barrels per day; and North Atlantic at 460,000 to 480,000 barrels per day. We expect refining cash operating expenses in the third quarter to be approximately $4.05 per barrel. Our ethanol segment is expected to produce a total of 4.3 million gallons per day in the third quarter. Operating expenses should average $0.40 per gallon, which includes $0.06 per gallon for noncash costs such as depreciation and amortization. With respect to the renewable diesel segment, we expect sales volumes to be 750,000 gallons per day in 2019. Operating expenses in 2019 should be $0.45 per gallon, which includes $0.16 per gallon for noncash costs such as depreciation and amortization. For 2019, we expect G&A expenses, excluding corporate depreciation, to be approximately $840 million. The annual effective tax rate is still estimated at 23%. For the third quarter, net interest expense should be $114 million and total depreciation and amortization expense should be approximately $560 million. Lastly, we still expect the RINs expense for the year to be between $300 million and $400 million. That concludes our opening remarks. [Operator Instructions].
