Kevin J. Mitchell
Executive Vice President, Finance and Chief Financial Officer at Phillips 66
Thank you, Mark. And hello, everyone.
Starting with an overview on Slide 4, we summarize our financial results for the year. Adjusted earnings were $2.5 billion or $5.70 per share. We generated $6 billion of operating cash flow or $3.9 billion excluding working capital. These results reflect our highest annual earnings for the Midstream, Chemicals and Marketing and Specialties segments. Cash distributions from equity affiliates totaled $3 billion, including a record $1.6 billion from CPChem. We ended 2021 with a net debt to capital ratio of 34%. Our adjusted after-tax return on capital employed for the year was 9%.
Slide 5 shows the change in cash during the year. We started the year with $2.5 billion in cash. Cash from operations was $6 billion. This included a working capital benefit of $2.1 billion, mainly due to the receipt of tax refunds, as well as the impact of rising prices on our net payable position. During the year, we paid down $1.5 billion of debt. In November, both S&P and Moody's revised their outlooks from negative to stable. We are committed to further deleveraging as we continue to prioritize our strong investment grade credit ratings. We funded $1.9 billion of capital spending and returned $1.6 billion to shareholders through dividends. Our ending cash balance increased to $3.1 billion.
Slide 6 summarizes our fourth quarter results. Adjusted earnings were $1.3 billion or $2.94 per share. We generated operating cash flow of $1.8 billion, including a working capital benefit of $412 million and cash distributions from equity affiliates of $757 million. Capital spending for the quarter was $597 million. $265 million was for growth projects, which included approximately $100 million for retail investments in the Marketing business. We paid $403 million in dividends.
Moving to Slide 7. This slide highlights the change in adjusted results from the third quarter to the fourth quarter, a decrease of $105 million. Our adjusted effective income tax rate was 20% for the fourth quarter.
Slide 8 shows our Midstream results. Fourth quarter adjusted pre-tax income was $668 million, an increase of $26 million from the previous quarter. Transportation contributed adjusted pre-tax income of $273 million, up $19 million from the prior quarter. The increase mainly reflects the recognition of deferred revenue.
NGL and other adjusted pre-tax income was $284 million compared with $357 million in the third quarter. The decrease was primarily due to lower unrealized investment gains related to Novonix, partially offset by higher volumes at Sweeny Hub and favorable inventory impacts. Our investment in Novonix is mark-to-market at the end of each reporting period. The total value of the investment, including foreign exchange impacts, increased $146 million in the fourth quarter compared to an increase of $224 million in the third quarter. The fractionators at the Sweeny Hub averaged a record 417,000 barrels per day, and the Freeport LPG export facility loaded a record 45 cargoes in the fourth quarter.
DCP Midstream adjusted pre-tax income of $111 million was up $80 million from the previous quarter, mainly due to favorable hedging impacts in the fourth quarter compared to negative hedge results in the third quarter. The actual hedge benefit recognized in the fourth quarter amounted to approximately $50 million.
Turning to Chemicals on Slide 9. Chemicals fourth quarter adjusted pre-tax income of $424 million was down $210 million from the third quarter. Olefins and Polyolefins adjusted pre-tax income was $405 million. The $208 million decrease from the previous quarter was primarily due to lower polyethylene margins, reduced sales volumes as well as increased utility costs. Global O&P utilization was 97% for the quarter. Adjusted pre-tax income for SA&S was $37 million compared with $36 million in the third quarter. During the fourth quarter, we received $479 million in cash distributions from CPChem.
Turning to Refining on Slide 10. Refining fourth quarter adjusted pre-tax income was $404 million, an improvement of $220 million from the third quarter, driven by higher realized margins and improved volumes. This was partially offset by higher costs. Realized margins for the quarter increased by 35% to $11.60 per barrel. Impacts from lower market crack spreads were more than offset by lower RIN costs from a reduction in our estimated 2021 compliance year obligation and lower RIN prices.
In addition, we had favorable inventory impacts and improved clean product differrentials. Refining adjusted results reflect approximately $230 million related to the EPA's proposed reduction of the RVO, of which about 75% applies to the first three quarters of the year. Pre-tax turnaround costs were $106 million, up from $81 million in the prior quarter. Crude utilization was 90% in the fourth quarter and clean product yield was 86%.
Slide 11 covers market capture. The 3:2:1 market crack for the fourth quarter was $17.93 per barrel compared to $19.44 per barrel in the third quarter. Realized margin was $11.60 per barrel and resulted in an overall market capture of 65%. Market capture in the previous quarter was 44%. Market capture is impacted by the configuration of our refineries. Our refineries are more heavily weighted toward distillate production and the market indicator. During the quarter, the distillate crack increased $3.10 per barrel and the gasoline crack decreased $3.76 per barrel.
Losses from secondary products of $1.88 per barrel improved $0.10 per barrel from the previous quarter due to increased butane blending into gasoline. Our feedstock advantage of $0.18 per barrel improved by $0.17 per barrel from the prior quarter. The other category reduced realized margins by $2.02 per barrel. This category includes RINs, freight costs, clean product realizations and inventory impacts.
Moving to Marketing and Specialties on Slide 12. Adjusted fourth quarter pre-tax income was $499 million compared with $547 million in the prior quarter. Marketing and other decreased $52 million from the prior quarter. This was primarily due to lower marketing fuel margins and volumes as well as higher costs. Specialties generated fourth quarter adjusted pre-tax income of $97 million, up from $93 million in the prior quarter.
On Slide 13, the corporate and other segment had adjusted pre-tax costs of $245 million, an increase of $15 million from the prior quarter. This was primarily due to higher employee-related costs and net interest expense.
Slide 14 shows the change in cash during the fourth quarter. We had another strong quarter for cash. This is the third consecutive quarter that our operating cash flow enabled us to return cash to shareholders, invest in the business, pay down debt while increasing our cash balance. This concludes my review of the financial and operating results.
Next, I'll cover a few outlook items for the first quarter and the full year. In Chemicals, we expect the first quarter global O&P utilization rate to be in the mid-90s. In Refining, we expect the first quarter worldwide crude utilization rate to be in the high-80s and pre-tax turnaround expenses to be between $120 million and $150 million. We anticipate first quarter corporate and other costs to come in between $230 million and $250 million pre-tax.
For 2022, we plan full-year turnaround expenses to be between $800 million and $900 million pre-tax. We expect corporate and other costs to be in the range of $900 million to $950 million. We anticipate full year D&A of about $1.4 billion. And finally, we expect the effective income tax rate to be in the 20% to 25% range.
Now, we will open the line for questions.
