Thank you, Mark. Hello, everyone. Starting with an overview on Slide four, we summarize our second quarter results. We reported earnings of $296 million. Excluding special items, we had adjusted earnings of $329 million or $0.74 per share. We generated operating cash flow of $1.7 billion, including a working capital benefit of $833 million and cash distributions from equity affiliates of $612 million. Capital spending for the quarter was $380 million, including $179 million for growth projects. We paid $394 million in dividends.
Moving to Slide five. This slide shows the change in adjusted results from the first quarter to the second quarter, an increase of $838 million. Pretax income improved across all segments, with the largest contribution from Chemicals. Our adjusted effective income tax rate was 19%.
Slide six shows our Midstream results. Second quarter adjusted pretax income was $316 million, an increase of $40 million from the previous quarter. Transportation contributed adjusted pretax income of $224 million, up $18 million from the previous quarter. The increase was due to improved volumes from higher refinery utilization, partially offset by higher costs due to the timing of maintenance and asset integrity work. NGL and other adjusted pretax income was $83 million.
The $47 million increase from the prior quarter was mainly due to lower operating costs and higher volumes, reflecting recovery from the winter storms. The Sweeny fractionation complex averaged 380,000 barrels per day and the Freeport LPG export facility loaded a record 42 cargoes in the second quarter. DCP Midstream adjusted pretax income of $9 million, was down $25 million from the previous quarter, mainly due to lower mark-to-market hedging results from higher natural gas and NGL prices.
Turning to Chemicals on Slide seven. Second quarter adjusted pretax income was $657 million, up $473 million from the first quarter. This is the highest quarterly earnings for Chemicals since the joint venture was formed in 2000. Olefins and Polyolefins adjusted pretax income was $593 million. The $419 million increase from the previous quarter was driven by strong demand, tight supplies and recovery from the winter storms that contributed to higher margins and lower utility costs.
The industry chain margin increased over $0.17 per pound to a record $0.62 per pound. Global O&P utilization was 102% for the quarter. Adjusted pretax income for SA&S increased $55 million. The increase primarily reflects improved margins due to tight industry supplies following the winter storms as well as lower turnaround costs. During the second quarter, we received $322 million in cash distributions from CPChem.
Turning to Refining on Slide eight. Refining second quarter adjusted pretax loss was $706 million, an improvement of $320 million from the first quarter. The improvement was driven by lower utility and turnaround costs and higher volumes. This was partially offset by lower realized margins. Improved market crack spreads were more than offset by higher RIN costs, lower electricity sales in the Texas market, decreased secondary product margins, lower clean product differentials and inventory impacts.
Pretax turnaround costs were $118 million, down from $192 million in the prior quarter. Crude utilization was 88% compared with 74% last quarter. The second quarter clean product yield was 82%. Slide nine covers market capture. The 3:2:1 market crack for the second quarter was $17.76 per barrel compared to $13.23 per barrel in the first quarter. Realized margin was $3.92 per barrel and resulted in an overall market capture of 22%. Market capture in the previous quarter was 33%. Market capture is impacted by the configuration of our refineries. Our refineries are more heavily weighted toward distillate production than the market indicator.
During the quarter, the gasoline crack improved $5.68 per barrel, while the distillate crack increased $2.20 per barrel. Losses from secondary products of $2.38 per barrel were $1.09 per barrel higher than the previous quarter as crude prices strengthened. These stock costs improved $0.36 per barrel compared to the prior quarter. The other category reduced realized margins by $7.84 per barrel. This category includes RINs, freight costs, new product realizations and inventory impacts.
Moving to Marketing and Specialties on Slide 10. Adjusted second quarter pretax income was $479 million compared with $290 million in the prior quarter. Marketing and other increased $181 million due to higher domestic margins and volumes, reflecting strong demand in key markets. Refined product exports in the second quarter were 216,000 barrels per day. Specialties generated second quarter adjusted pretax income of $87 million, up from $79 million in the prior quarter.
Slide 11 shows the change in cash for the quarter. We started the quarter with a $1.4 billion cash balance. Cash from operations was $1.7 billion. This included a working capital benefit of $833 million. In June, we received a $1.1 billion U.S. federal income tax refund, which is reflected in working capital. Cash from operations, excluding working capital, was $910 million, which more than covered $380 million of capital spend and $394 million for the dividend. The other category includes a $90 million loan to our WRB joint venture. Our ending cash balance was $2.2 billion.
This concludes my review of the financial and operating results. Next, I'll cover a few outlook items. In Chemicals, we expect the third quarter global O&P utilization rate to be in the mid-90s. In Refining, crude utilization will be adjusted according to market conditions. In July, utilization averaged around 98%. We expect third quarter pretax turnaround expenses to be between $120 million and $150 million. We anticipate third quarter Corporate and Other costs to come in between $240 million and $250 million pretax.
Now we will open the line for questions.
