We welcome any questions you may have about our comments or any other aspect of our review. Feel free to call us at the telephone numbers listed at the end of this letter. Cover Page 1. Please delete the reference to Lehman Brothers and J.P. Morgan as "Joint Book-Running Managers" on the front cover page of your prospectus. Also, please delete the references to "senior co- managers" and "co-managers." Prospectus Summary, page 1 The Offering, page 9 2. We note your response to comment 13 of our letter dated July 1, 2005, as well as the disclosure appearing in Summary Historical and Pro Forma Combined Financial Data of Amendment No. 4. Revise your summary discussion of the offering to disclose the aggregate value of the transaction to Kerr-McGee, including your transfer of "cash on hand in excess of $40 million." Summary Historical and Pro Forma Combined Financial Data, page 11 3. You state in footnote 4 on page 13 that cash flows from operating activities were reduced by $165 million related to the repurchase of previously sold accounts receivable. Our understanding is that the termination of the accounts receivable monetization program resulted in a one-time reduction in cash flows from operations of up to $165 million from the date of termination until you began collecting on post-termination accounts receivable. It appears that the time lag in collections resulting from the program termination contributed to the decrease in cash flows from operations. Please revise your disclosures on pages 13 and 60 to clarify how cash flows from operating activities were affected by the termination of the accounts receivable monetization program. Risk Factors, page 16 Hazards associated with chemical manufacturing could adversely affect. . . , page 18 4. We note your response to comment 4 in our letter dated November 7, 2005. Please revise to give investors a sense for the likelihood of the risk that you disclose in the paragraph following the bullet points.

In that regard, we reissue comment 4. Unaudited Pro Forma Combined Financial Statements, page 38 5. Please disclose the types of selling, general and administrative costs included in pro forma adjustment one. 6. Please revise to present the pro forma adjustments related to the receipt and use of offering proceeds in a separate column from your other pro forma adjustments. 7. Please revise the descriptions of pro forma adjustments two and three to show the computation of each adjustment, including the interest rates used for each debt instrument. If true, please confirm that interest expense is based on current rates. Please also ensure that the final terms of the debt agreements are reflected in these adjustments and elsewhere in the document, including discussion of your debt covenants. 8. Please note that it is appropriate to give pro forma effect to the elimination of interest associated with historical amount due to Kerr-McGee only to the extent that is eliminated by the pro forma transactions. Further, your pro forma adjustment to eliminate interest, calculated based on the amount due to Kerr-McGee as of a recent date, may require downward adjustment unless the recent amount due is less than the amount due at any date during the periods presented. 9. Please revise the description of pro forma adjustment 13 to disclose the assumptions used to determine the plan obligation of $442.3 million.
