Form 10-K for Fiscal Year Ended December 31, 2009
Filed on February 26, 2010
File No. 001-12387

Dear Mr. Shenk, Ms. Chaudhry and Mr. Brown:

Reference is made to your letter, dated September 28, 2010 (the “Comment Letter”), setting forth the comments of the staff (the “Staff”) of the United States Securities and Exchange Commission (the “Commission”) concerning Tenneco Inc.’s (“Tenneco”) Form 10-K for the fiscal year ended December 31, 2009 (the “2009 10-K”) and Form 10-Q for the fiscal quarter ended March 31, 2010.

Set forth below are Tenneco’s responses to the Comment Letter. To facilitate the Staff’s review, the headings and numbered comments from the Comment Letter have been repeated in this letter in bold face type, and Tenneco’s response immediately follows each numbered comment in regular type.

Form 10-K for Fiscal Year Ended December 31, 2009

Selected Consolidated Financial Data, page 36

In accordance with Item 301 of Regulation S-K, please revise your disclosure in Selected Financial Data to describe or cross-reference to those factors that have materially affected the comparability of the information presented.

Response:

We will add the following cross-reference at the beginning of Item 6 in our future filings.

“The following data should be read in conjunction with Item 7 — ‘Management’s Discussion and Analysis of Financial Condition and Operations’ and our consolidated

United States Securities and Exchange Commission
October 22, 2010
Page 2

financial statements in Item 8 — ‘Financial Statements and Supplementary Data.’ These items include discussions of factors affecting comparability of the information shown above.”

In the event that there are major factors such as accounting changes, business combinations or dispositions of business operations that materially affect the comparability of the information reflected in the selected financial data, we will also add footnotes at the bottom of the tables in Item 6 to describe such factors and provide a cross-reference to where those factors are described in greater detail.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Executive Summary, page 38

We note your statement that other than the impact from production shutdowns during the second quarter, you incurred no other economic loss from the bankruptcy filings of Chrysler or General Motors. Please tell us and revise your disclosure to disclose what the impact of these production shutdowns was.

Response:

The paragraph will be revised in future filings as follows.

“Other than the impact of production shutdowns at Chrysler and General Motors plants in North America during the second and third quarters of 2009, we incurred no other economic loss from the bankruptcy filings of these two customers. We collected substantially all of our pre-petition receivables from Chrysler Group LLC and Chrysler Group LLC has assumed substantially all of the contracts which we had with Chrysler LLC. We collected substantially all of our pre-petition receivables from General Motors Company and General Motors Company has assumed substantially all of the contracts which we had with General Motors Corporation. Substantially all of our customers in North America significantly reduced production volumes during this time period in response to lower purchases of new vehicles. The impact on our results of operations of this lower production, including the production shutdowns at Chrysler and General Motors, is discussed later in this MD&A under ‘— Results from Operations.’”

Results from Operations, page 41

We note that a significant portion of your results of operations disclosure with regards to revenues is dedicated to stating, in narrative text form, dollar and percentage changes in the different revenue categories. In addition, while you discuss certain factors to which changes are attributable, you do not quantify some of the individual factors. For example, you state that excluding $6 million in unfavorable currency, aftermarket revenues were up $16 million driven by stronger ride control volumes and pricing, partially offset by lower emission control volumes, but you do not quantify these individual factors. Please ensure that all material

United States Securities and Exchange Commission
October 22, 2010
Page 3

factors are quantified and analyzed to the extent practicable. In addition, we believe your disclosures would be more informative, transparent and easily understood by:

	•		using of tables to present dollar and percentage changes in the different revenue categories, rather than including such information in narrative text form;

	•		using tables to list, quantify, and sum all of the material individual factors to which changes in revenues are attributable; and

	•		refocusing the narrative text portion of the disclosure on analysis of the underlying business reasons for the individual factors in the tables above.

We believe such enhancements will significantly improve the ease of use of the information to present in your MD&A discussion and allow you to focus the narrative text on discussion and analysis of these figures as seen through the eyes of management. Please revise future filings accordingly. Please provide us a sample of your proposed revised disclosure as part of your response.

Response:

In future filings, following the tables that display detailed information regarding our revenues (shown on pages 40 and 41 of the 2009 10-K), we will add a table showing the year-over-year dollar and percentage changes for Revenues and for Revenues Excluding Currency and Substrate Sales. Following is a sample of this new table:

In addition, we will add a table showing the light vehicle industry production volumes for the comparative years, including unit and percentage changes. Following is a sample of this new table:

Light Vehicle Industry Production by Region
(According to Global Insight, February 2010)


	Year Ended December 31,
	2009		2008		Change			% Change
	(Number of Vehicles in Millions)
North America		8.6		12.6		(4.0	)		(32	%)
Europe		16.9		21.2		(4.3	)		(20	%)
South America		3.7		3.8		(0.1	)		(3	%)
India		2.4		2.1		0.3			16	%
China		12.9		8.6		4.3			50	%
Australia		0.2		0.3		(0.1	)		(32	%)

The following is a sample of our narrative disclosure, consisting of a revised version of the related narrative text used in the 2009 10-K for the fiscal year ended December 31, 2009:

“In North America, the light vehicle industry production decline in 2009 compared to 2008 was caused by the economic recession and the bankruptcies of General Motors and Chrysler. The recession also drove commercial vehicle production for Class 8 and Class 4

United States Securities and Exchange Commission
October 22, 2010
Page 5

through 7 vehicles down 38 percent and 39 percent, respectively. The 23 percent decrease in our North American OE revenue excluding currency and substrate sales was primarily due to these significant industry production declines. The platforms we supply were impacted less severely than the overall industry, resulting in a lower percentage decline in our OE revenues than the overall industry experienced.

The 3 percent increase in our North American aftermarket revenue excluding currency was mostly driven by increases in ride control products sales volume and better year over year pricing, driving higher revenues of $7 million and $9 million, respectively. A decline in aftermarket emission control products sales volume drove $15 million in lower revenue, which was partially offset by better emission control product pricing of $11 million.

In Europe, industry light vehicle production also declined in 2009 due to the global recession. Our European OE revenues excluding currency and substrate sales were down less than the overall industry because the platforms we supply were impacted less severely than the overall industry. In particular, our ride control revenues benefited from a vehicle mix more heavily weighted toward the small A/B segment vehicles which have been better sellers under various government incentive programs. The ride control business also benefited from new vehicle launches, including new CES business. Our emission control business also experienced a decline in revenue that was less than the overall industry production volume decline due to a favorable platform mix. We also recovered $64 million less year over year in alloy surcharges in our emission control business due to lower alloy surcharge costs.

The 9 percent decline in our European aftermarket revenue excluding currency in both product lines was primarily due to a $52 million volume-driven revenue loss resulting from overall recession-related market declines, particularly in our heavy duty ride control products and in the ride control markets in Eastern Europe where economies were more severely impacted by the economic crisis, partially offset by $12 million of improved pricing.

Light vehicle industry production volume was down 3 percent in South America and up 16 percent in India. Our South America and India revenues excluding currency and substrate sales improved by $30 million primarily due to our favorable platform mix in South America and higher production volume in India as well as $17 million in favorable pricing changes.

Despite the global recession, China light vehicle industry production volume was up significantly. Our Asia revenue excluding currency and substrates improved primarily due to increased light vehicle industry production volume in China. In Australia, the light vehicle industry production volume decline in 2009 was the primary driver of the decrease in our revenue excluding currency and substrates. The aftermarket business was impacted less severely than the OE business, resulting in an overall lower percentage revenue decline for our total Australia business than the OE production volume decline.”

In future filings, please quantify, discuss, and analyze the changes in costs of sales. In your revised disclosure, please quantify and discuss the significant components of costs of sales, such as labor, materials, or any other components, to the extent material. Please provide us a sample of your proposed revised disclosure as part of your response.

Response:

We will expand, and further quantify, the discussion of gross margin on page 39 of the 2009 10-K, most of which relates to factors that drove changes in our cost of sales, to include other factors that relate directly to our cost of sales. As a sample of our proposed revised disclosure, following is an expanded and revised version of the paragraph on page 39 in which we discuss gross margin.

“Gross margin for 2009 was 16.6 percent, up 2.2 percentage points, from 14.4 percent in 2008. The gross margin improvement was driven by currency gains (0.4%) and improvement in our cost of sales resulting from our restructuring activities in 2008 and lower year-over-year restructuring and related expenses (0.5%), material cost management (2.6%) and improved manufacturing efficiencies (0.7%). Lower OE production volumes and the related fixed cost absorption partially offset these improvements (1.9%).”

In future filings, please quantify, discuss, and analyze the changes in other material expense accounts such as your goodwill impairment charge, engineering expense, research and development expense, selling, general and administrative expense and depreciation and amortization.

Response: We discuss other material expense accounts, including material goodwill impairment charges, engineering, research and development expense, and selling, general and administrative expense under the “Executive Summary” and “Critical Accounting Policies” sections of Item 7. We will discuss depreciation and amortization expense in future filings if we experience any material year-over-year changes in this expense account during the three years presented in the consolidated statements of income (loss).

Item 8. Financial Statements and Supplementary Data

Note 5. Long Term Debt, Short Term Debt, and Financing Arrangements

Senior Credit Facility — Other Terms and Conditions, page 92

We note that your senior credit facility agreement provides the ability to refinance your senior subordinated notes and/or your senior secured notes in exchange for shares of common stock, other debt, or in an amount equal to the sum of proceeds of certain equity offerings. Please tell us the purpose of these provisions, explain to us

United States Securities and Exchange Commission
October 22, 2010
Page 7

how they work in further detail and how you accounted for them, citing any accounting literature that you relied upon.

Response:

The covenants in our senior credit facility agreement generally prohibit us from repaying or refinancing our senior secured notes (which were retired in September), senior unsecured notes and senior subordinated notes. These negative covenants are for the benefit and protection of the lenders under our senior credit agreement, which is a secured credit facility, in that they serve as limitations on our ability to repay or refinance other indebtedness that is actually or structurally subordinate to the senior credit facility obligations.

Notwithstanding these general prohibitions, our senior credit agreement does provide for certain specified circumstances in which we are permitted to repay or refinance our notes. One such permitted circumstance allows us to repay the notes in exchange for permitted refinancing indebtedness (as defined in the senior credit agreement) or in exchange for shares of our common stock.

While the senior credit agreement would not prohibit us from consummating such an exchange, we do not, under the terms of the agreements governing our outstanding notes, have the right to repay the notes by way of a direct exchange of other indebtedness or shares of our common stock. Accordingly, we did not account for any such exchange features in our financial statements.

In future filings, we will revise our disclosure to further explain the purpose of these provisions in the senior credit agreement and how they operate.

Form 10-Q for Fiscal Quarter Ended March 31, 2010

We note that you adopted the new accounting guidance for transfers of financial assets. We further note that you now account for your North American securitization program as a secured borrowing as it no longer meets the conditions required for sales accounting treatment and that you continue to account for your European securitization programs as sales as they continue to qualify for sales accounting treatment. Please tell us and revise future filings to disclose the following: (1) how the North American securitization program differs from the European securitization programs (2) how you determined that the North American securitization program no longer qualified for and that the European programs continues to qualify for sales accounting treatment.

Response:

Following is an explanation and revised disclosure describing how the North American and European programs differ and how these differences affect their accounting treatment.

United States Securities and Exchange Commission
October 22, 2010
Page 8

“We adopted the amended accounting guidance (ASC Topic 860, Accounting for Transfers of Financial Assets) effective January 1, 2010. Prior to the adoption of this new guidance, we accounted for activities under our North American and European accounts receivable securitization programs as sales of financial assets to our banks. The new accounting guidance changed the conditions that must be met for the transfer of financial assets to be accounted for as a sale. The new guidance adds additional conditions that must be satisfied for transfers of financial assets to be accounted for as sales when the transferor has not transferred the entire original financial asset, including the requirement that no partial interest holder have rights in the transferred asset that are subordinate to the rights of other partial interest holders. In our North American accounts receivable securitization programs, we transfer a partial interest in a pool of receivables and the interest that we retain is subordinate to the transferred interest. Accordingly, beginning January 1, 2010, we account for our North American securitization program as a secured borrowing. In our European programs, we transfer accounts receivables in their entirety to the acquiring entities and satisfy all of the conditions established under amended ASC Topic 860 to report the transfer of financial assets in their entirety as a sale.” [Remainder of paragraph is unchanged.]
