Pierre Breber
Chief Financial Officer at Chevron
Thanks, Mike. We delivered another quarter with strong earnings, cash flow and ROCE. This quarter's results included two special items: a one-time tax benefit of $560 million in Nigeria and pension settlement costs of $40 million. Foreign currency benefits were $285 million. The appendix of this presentation contains a reconciliation of non-GAAP measures.
Organic capex this quarter included about $200 million for PDC legacy operations after closing in August. Our balance sheet remains strong, ending the quarter with a net debt ratio in the single digits.
Another quarter of solid cash flow enabled us to deliver on all of our financial priorities. Despite restrictions during the PDC transaction, we were able to repurchase well over $3 billion in Chevron shares. Cash used to reduce debt was primarily related to PDC's higher cost borrowing. Cash balances ended the quarter near $6 billion, a little above what's needed to run our businesses.
Adjusted third quarter earnings were down $5.1 billion versus the same quarter last year. Adjusted upstream earnings were lower mainly due to realizations and negative timing effects. Higher unfavorable discrete tax charges and exploration expenses were partly offset by lower DD&A, Venezuela cash recoveries and other favorable items. Adjusted downstream earnings decreased primarily due to a negative swing in timing effects and lower marketing margins.
Compared with the last quarter, adjusted earnings were down just over $50 million. Adjusted upstream earnings were roughly flat as higher prices and volumes were offset by unfavorable discrete tax charges and negative timing effects due to the rise in prices. DD&A and opex were both higher in part due to the addition of PDC legacy assets for two months in the quarter.
Adjusted downstream earnings increased primarily due to higher refining margins, partially offset by unfavorable timing effects. All other was down on unfavorable tax items and decreased interest income in line with lower cash balances.
Third quarter oil equivalent production was up 6% over last quarter primarily due to two months of legacy PDC production. This was partly offset by a planned turnaround at TCO and pit stop at Gorgon. The Permian, excluding legacy PDC, was down 2% due to lower non-operated production. Company-operated production was flat with the second quarter.
Now looking ahead, our fourth quarter estimate for turnarounds and downtime includes approximately 30,000 barrels of oil equivalent per day for Tamar. We anticipate affiliate dividends in the fourth quarter to be largely from TCO. As a reminder, we recorded a 15% withholding tax on TCO dividends.
Due to the pending transaction with Hess, share repurchases will be restricted pursuant to SEC regulations. Chevron expects share repurchases in the fourth quarter to be around $3 billion, plus or minus 20%, depending primarily on the timing of the Hess definitive proxy statement mailing.
In summary, our actions and performance show that Chevron keeps delivering strong results. With a strategy that remains clear and consistent, we're well positioned to deliver value to our shareholders in any environment.
With that, I'll turn it back to Jake.
