Vice President, Investor Relations at Valero Energy
Thanks. Lane. For the third quarter of 2023, net income attributable to Valero stockholders was $2.6 billion or $7.49 per share compared to $2.8 billion or $7.19 per share for the third quarter of 2022. Adjusted net income attributable to Valero stockholders was $2.8 billion or $7.14 per share for the third quarter of 2022. The Refining segment reported $3.4 billion of operating income for the third quarter of 2023 compared to $3.8 billion for the third quarter of 2022.
Refining throughput volumes in the third quarter of 2023 averaged three million barrels per day, implying a throughput capacity utilization of 95%. Refining cash operating expenses were $4.91 per barrel in the third quarter of 2023, higher than guidance of $4.70 per barrel, primarily attributed to higher-than-expected energy prices. Renewable Diesel segment operating income was $123 million for the third quarter of 2023 compared to $212 million for the third quarter of 2022. Renewable Diesel sales volumes averaged three million gallons per day in the third quarter of 2023, which was 761,000 gallons per day higher than the third quarter of 2022.
The higher sales volumes in the third quarter of 2023 were due to the impact of additional volumes from the DGD Port Arthur plant, which started up in the fourth quarter of 2022. Operating income was lower than the third quarter of 2022, primarily due to lower Renewable Diesel margin in the third quarter of 2023. The Ethanol segment reported $197 million of operating income for the third quarter of 2023 compared to $1 million for the third quarter of 2022. Ethanol production volumes averaged 4.3 million gallons per day in the third quarter of 2023, which was 831,000 gallons per day higher than the third quarter of 2022.
Operating income was higher than the third quarter of 2022, primarily as a result of higher production volumes and lower corn prices in the third quarter of 2023. For the third quarter of 2023, G&A expenses were $250 million and net interest expense was $149 million. Depreciation and amortization expense was $682 million and income tax expense was $813 million for the third quarter of 2023. The effective tax rate was 23%. Net cash provided by operating activities was $3.3 billion in the third quarter of 2023, included in this amount was a $33 million favorable change in working capital and $82 million of adjusted net cash provided by operating activities associated with other joint venture member share of DGD.
Excluding these items, adjusted net cash provided by operating activities was $3.2 billion in the third quarter of 2023. Regarding investing activities, we made $394 million of capital investments in the third quarter of 2023, of which $303 million was for sustaining the business including costs for turnarounds, catalysts, and regulatory compliance, and $91 million was for growing the business. Excluding capital investments attributable to the other joint venture member share of DGD, capital investments attributable to Valero were $352 million in the third quarter of 2023.
Moving to financing activities, we returned $2.2 billion to our stockholders in the third quarter of 2023, of which $360 million was paid as dividends and $1.8 billion was for the purchase of approximately 13 million shares of common stock resulting in a payout ratio of 68% of adjusted net cash provided by operating activities. This results in a year-to-date payout ratio of 58% as of September 30, 2023. With respect to our balance sheet, we ended the quarter with $9.2 billion of total debt, $2.3 billion of finance lease obligations, and $5.8 billion of cash-and-cash equivalents. Debt-to-capitalization ratio net of cash-and-cash equivalents was 17% as of September 30, 2023 and we ended the quarter well-capitalized with $5.4 billion of available liquidity, excluding cash.
Separately, as reported by Navigator, last week they canceled their CO2 pipeline project. We still see carbon capture and storage as a strategic opportunity to reduce the carbon intensity of conventional ethanol, which would also qualify[phonetic] as a feedstock for sustainable aviation fuel. Without carbon capture and storage conventional ethanol does not have a pathway into SAF under today's policies. We continue to evaluate other projects to sequester CO2. Turning to guidance, we still expect capital investments attributable to Valero for 2023 to be approximately $2 billion, which includes expenditures for turnarounds, catalysts, and joint-venture investments.
About $1.5 billion of that is allocated to sustaining the business and the balance to growth. For modeling our fourth-quarter operations we expect refining throughput volumes to fall within the following ranges. Gulf Coast at 1.77 million to 1.82 million barrels per day, Mid Continent at 445,000 to 465,000 barrels per day, West Coast at 245,000 to 265,000 barrels per day, and North Atlantic at 470,000 to 490,000 barrels per day. We expect refining cash operating expenses in the fourth quarter to be approximately $4.60 per barrel. With respect to the Renewable Diesel segment, we expect sales volumes to be approximately 1.2 billion gallons in 2023.
Operating expenses in 2023 should be $0.49 per gallon, which includes $0.19 per gallon for non-cash costs such as depreciation and amortization. Our Ethanol segment is expected to produce 4.4 million gallons per day in the fourth quarter. Operating expenses should average $0.39 per gallon, which includes $0.05 per gallon for non-cash costs such as depreciation and amortization. For the fourth quarter, net interest expense should be about $145 million and total depreciation and amortization expense should be approximately $690 million.
For 2023, we expect G&A expenses to be approximately $925 million. That concludes our opening remarks. Before we open the call to questions, please adhere to our protocol of limiting each turn in the Q&A to two questions. If you have more than two questions, please rejoin the queue as time permits to ensure other callers have time to ask their questions.
