Executive Vice President and Chief Financial Officer at Phillips 66
Thank you, Mark. Starting with an overview on Slide 5, we summarize our financial results for the year. Adjusted earnings were $8.9 billion or $18.79 per share. The $442 million decrease in the fair value of our investment in NOVONIX reduced earnings per share by $0.71.
We generated $10.8 billion of operating cash flow. Cash distributions from equity affiliates were $1.7 billion, including $574 million from CPChem. We ended 2022 with a net debt-to-capital ratio of 24%. Our adjusted after-tax return on capital employed for the year was 22%.
Slide 6 shows the change in cash during the year. We started the year with $3.1 billion in cash and generated record cash flow during the year. Cash from operations was $10.8 billion. We received net loan repayments from equity affiliates of $590 million. During the year, we paid down $2.4 billion of debt. This includes $430 million of debt paid down by DCP Midstream since we began consolidating effective August 18. We funded $2.2 billion of capital spending and returned $3.3 billion to shareholders, including $1.5 billion of share repurchases. The other category includes the redemption of DCP Midstream's Series A preferred units of $500 million. Our ending cash balance increased by $3 billion to $6.1 billion.
Slide 7 summarizes our fourth quarter results. Adjusted earnings were $1.9 billion or $4 per share. The $11 million decrease in the fair value of our investment in NOVONIX reduced earnings per share by $0.02. We generated operating cash flow of $4.8 billion, including a working capital benefit of $2.1 billion and cash distributions from equity affiliates of $261 million. Capital spending for the quarter was $713 million, including $310 million for growth projects. We returned $1.2 billion to shareholders through $456 million of dividends and $753 million of share repurchases. We ended the quarter with 466 million shares outstanding.
Moving to Slide 8. This slide highlights the change in adjusted results by segment from the third quarter to the fourth quarter. During the period, adjusted earnings decreased $1.2 billion, mostly due to lower results in Refining and Marketing & Specialties. In the fourth quarter, we made certain changes to the composition and reporting of our operating segment results. Our slides reflect these changes and prior period results have been recast for comparative purposes. The 2022 and 2021 quarterly information has been recast and is included in our supplemental information.
Slide 9 shows our Midstream results. Fourth quarter adjusted pretax income was $674 million compared with $608 million in the previous quarter. Transportation contributed to adjusted pretax income of $237 million, up $8 million from the prior quarter. NGL and Other adjusted pretax income was $448 million compared to $412 million in the third quarter. The decrease -- the increase was primarily due to record fractionation volumes as well as a full quarter of consolidating DCP Midstream, Sand Hills pipeline and Southern Hills pipeline.
The fractionators at the Sweeny Hub averaged a record 565,000 barrels per day, reflecting the start-up of Frac 4 at the end of the third quarter. The Freeport LPG export facility loaded a record 271,000 barrels per day in the fourth quarter. Our NOVONIX investment is mark-to-market each quarter. The fair value of the investment, including foreign exchange impacts, decreased $11 million in the fourth quarter compared with a decrease of $33 million in the third quarter.
Turning to Chemicals on Slide 10. Chemicals had fourth quarter adjusted pretax income of $52 million compared with $135 million in the previous quarter. The decrease was mainly due to lower margins and volumes, partially offset by decreased utility costs and the impact of legal accruals in the third quarter. Global olefins and polyolefins utilization was 83% for the quarter, reflecting planned turnaround activities and the impact of the winter storm in December.
Turning to Refining on Slide 11. Refining fourth quarter adjusted pretax income was $1.6 billion, down from $2.9 billion in the third quarter. The decrease was primarily due to lower realized margins. Our realized margins decreased by 27% to $19.73 per barrel, while the composite 3:2:1 RIN-adjusted market crack decreased by 16%. Turnaround costs were $236 million. Crude utilization was 91% in the fourth quarter and clean product yield was 86%.
Slide 12 covers market capture. We are now using a composite 3:2:1 RIN-adjusted market crack to be more consistent with peers and more comparable to our realized margin. The 3:2:1 RIN-adjusted market crack for the fourth quarter was $23.58 per barrel compared to $28.18 per barrel in the third quarter. Realized margin was $19.73 per barrel and resulted in an overall market capture of 84%. Market capture in the previous quarter was 95%. Market capture is impacted by the configuration of our refineries. We have a higher distillate yield and lower gasoline yield than the 3:2:1 market indicator.
During the fourth quarter, the distillate crack increased $8 per barrel and the gasoline crack decreased $10 per barrel. Losses from secondary products of $3.59 per barrel were $0.09 per barrel higher than the previous quarter. Our feedstock loss of $0.03 per barrel was $1.45 per barrel improved compared to the third quarter due to more favorable crude differentials. The other category improved realized margins by $0.46 per barrel. This category includes freight costs, clean product realizations and inventory impacts. Fourth quarter was $6.66 per barrel less than the previous quarter, primarily due to lower clean product realizations and inventory timing.
Moving to Marketing & Specialties on Slide 13. Adjusted fourth quarter pretax income was $539 million compared with $828 million in the prior quarter, mainly due to lower domestic and international marketing margins.
On Slide 14, the Corporate & Other segment had adjusted pretax costs of $280 million, $34 million higher than the prior quarter. The increase was mainly due to higher net interest expense as well as a transfer tax related to a foreign entity reorganization and higher employee-related expenses.
Slide 15 shows the change in cash during the fourth quarter. We had another strong quarter of cash generation. We started the quarter with a $3.7 billion cash balance. Cash from operations was $2.7 billion, excluding working capital. There was a working capital benefit of $2.1 billion, mainly reflecting a reduction in inventory and a decrease in our net accounts receivable position.
We received a loan repayment from an equity affiliate of $426 million. During the quarter, we repaid $500 million of senior notes due April 2023 and funded $713 million of capital spending. We returned $1.2 billion to shareholders through dividends and share repurchases. Additionally, the other category includes the redemption of DCP Midstream's Series A preferred units of $500 million. Our ending cash balance was $6.1 billion. 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-90%s. In Refining, we expect the first quarter worldwide crude utilization rate to be in the mid-80%s and turnaround expenses to be between $240 million and $270 million. We anticipate first quarter corporate and other costs to come in between $230 million and $260 million.
For 2023, Refining turnaround expenses are expected to be between $550 million and $600 million. We expect Corporate & Other costs to be in the range of $1 billion to $1.1 billion for the year. We anticipate full year D&A of about $2 billion. And finally, we expect the effective income tax rate to be between 20% and 25%.
Now, we will open the line for questions.
