Executive Vice President of Finance and Chief Finance Officer at Phillips 66
Thank you, Mark, and hello, everyone. Starting with an overview on slide four, we summarize our financial results for the quarter. Adjusted earnings were $595 million or $1.32 per share. The $158 million decrease in the fair value of our investment in NOVONIX reduced earnings per share by $0.27. We generated $1.1 billion of operating cash flow, including a working capital use of $115 million. We received distributions from equity affiliates of $585 million. Capital spending for the quarter was $370 million, including $221 million for growth projects. We paid $404 million in dividends. We ended the quarter with 481 million shares outstanding, including the 42 million shares issued for the PSXP merger.
Moving to slide five. This slide highlights the change in adjusted results by segment from the fourth quarter to the first quarter. During the period, adjusted earnings decreased $703 million, driven by lower results across all segments. slide six shows our Midstream results. First quarter adjusted pretax income was $242 million, a decrease of $426 million from the previous quarter. Transportation contributed adjusted pretax income of $278 million, in line with the previous quarter. NGL and other adjusted pretax income was $91 million compared with $138 million in the fourth quarter. The decrease was primarily due to the impact of rising prices on inventory, partially offset by improved butane and propane trading results. The fractionators at the Sweeny Hub averaged a record 423,000 barrels per day, and the Freeport LPG export facility loaded 43 cargoes in the first quarter.
Frac four is ahead of schedule and we expect start-up in the third quarter. DCP Midstream adjusted pretax income of $31 million was down $80 million from the previous quarter, mainly driven by unfavorable hedging impacts, partially offset by lower operating costs. The hedge loss recognized in the first quarter was approximately $50 million compared with a hedging gain of approximately $50 million in the fourth quarter. Beginning this quarter, we are showing our investment in NOVONIX as its own subsegment to separate it from our core Midstream businesses. This investment is marked-to-market at the end of each reporting period. The fair value of the investment, including foreign exchange impacts, decreased $158 million in the first quarter compared with an increase of $146 million in the fourth quarter. Our initial investment in NOVONIX of $150 million had a fair value of $362 million at the end of the first quarter.
Turning to Chemicals on slide seven. Chemicals' first quarter adjusted pretax income of $396 million was down $28 million from the fourth quarter. Olefins and Polyolefins adjusted pretax income was $377 million. The $28 million decrease from the previous quarter was primarily due to lower polyethylene margins as inventories normalized, following supply disruptions last year. This was partially offset by higher sales volumes. Global O&P utilization was 99% for the quarter. Adjusted pretax income for SA&S was $32 million, in line with the previous quarter. During the first quarter, we received $299 million in cash distributions from CPChem. Turning to Refining on slide eight. Refining first quarter adjusted pretax income was $140 million, down from $404 million in the fourth quarter. The decrease was mainly due to lower realized margins as well as lower clean product volumes driven by planned maintenance.
Realized margins for the quarter decreased by 9% to $10.55 per barrel. Favorable impacts from higher market cracks were more than offset by higher RIN costs, lower Gulf Coast clean product realizations and secondary product margins as well as inventory impacts. The higher RIN costs were primarily due to the fourth quarter recognition of the reduction in the 2021 compliance year obligation of approximately $230 million. Pretax turnaround costs were $102 million, down from $106 million in the prior quarter. Crude utilization was 89% in the first quarter and clean product yield was 84%. slide nine covers market capture. The 3:2:1 market crack for the first quarter was $21.93 per barrel compared to $17.93 per barrel in the fourth quarter. Realized margin was $10.55 per barrel and resulted in an overall market capture of 48%.
Market capture in the previous quarter was 65%. Market capture is impacted by the configuration of our refineries. Our refineries are more heavily weighted toward distillate production than the market indicator. The configuration impact was relatively flat quarter-on-quarter as lower clean product yield offset higher distillate cracks. Losses from secondary products of $3.05 per barrel were $1.17 per barrel higher than the previous quarter due to rising crude prices. Our feedstock advantage of $1.01 per barrel improved by $0.83 per barrel from the prior quarter. The other category reduced realized margins by $6.42 per barrel. This category includes RINs, clean product realizations, freight costs and inventory impacts. Moving to Marketing and Specialties on slide ten. Adjusted first quarter pretax income was $316 million compared with $499 million in the prior quarter. Marketing and Other decreased $199 million from the prior quarter.
This was primarily due to lower marketing margins, mainly resulting from rising spot prices as well as seasonally lower demand. Refined product exports in the first quarter were 134,000 barrels per day. Specialties generated first quarter adjusted pretax income of $113 million, up from $97 million in the prior quarter, mainly due to higher finished lubricant margins. slide 11 shows the change in cash during the first quarter. We had another strong quarter for cash generation. This was the fourth quarter in a row that cash flow from operations allowed us to return cash to shareholders, invest in our business and strengthen the balance sheet. We started the quarter with a $3.1 billion cash balance.
Cash from operations was $1.1 billion, which covered $370 million of capital spend and $404 million for the dividend, while also increasing our cash balance by $188 million. Our ending cash balance was $3.3 billion. In early April, we repaid $1.45 billion of maturing debt. This concludes my review of the financial and operating results. Next, I'll cover a few outlook items. In Chemicals, we expect the second quarter global O&P utilization rate to be in the mid-90s. In Refining, we expect the second quarter worldwide crude utilization rate to be in the low 90s and pretax turnaround expenses to be between $230 million and $250 million. We anticipate second quarter corporate and other costs to come in between $230 million and $250 million pretax. Now we will open the line for questions.
