CAUTIONARY STATEMENT FOR PURPOSES OF THE “SAFE HARBOR” PROVISIONS OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

This Quarterly Report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 concerning, among other things, our prospects and business strategies. These forward-looking statements are included in various sections of this report, including the section entitled “Outlook” appearing in Item 2 of this report. The words “may,” “will,” “believe,” “should,” “could,” “plan,” “expect,” “anticipate,” “estimate,” and similar expressions (and variations thereof), identify these forward-looking statements. Although we believe that the expectations reflected in these forward-looking statements are based on reasonable assumptions, these expectations may not prove to be correct. Because these forward-looking statements are also subject to risks and uncertainties, actual results may differ materially from the expectations expressed in the forward-looking statements. Important factors that could cause actual results to differ materially from the expectations reflected in the forward-looking statements include:

• general economic, business and market conditions;

• our ability to source and procure needed materials, components and other products and services in accordance with customer demand and at competitive prices;

• the cost and outcome of existing and any future claims, legal proceedings or investigations, including, but not limited to, any of the foregoing arising in connection with the ongoing global antitrust investigation, product performance, product safety or intellectual property rights;

• changes in capital availability or costs, including increases in our cost of borrowing (i.e., interest rate increases), the amount of our debt, our ability to access capital markets at favorable rates, and the credit ratings of our debt;

• changes in consumer demand, prices and our ability to have our products included on top selling vehicles, including any shifts in consumer preferences away from light trucks, which tend to be higher margin products for our customers and us, to other lower margin vehicles, for which we may or may not have supply arrangements;

• changes in consumer demand for our automotive, commercial or aftermarket products, or changes in automotive and commercial vehicle manufacturers’ production rates and their actual and forecasted requirements for our products due to difficult economic conditions;

• the overall highly competitive nature of the automobile and commercial vehicle parts industries, and any resultant inability to realize the sales represented by our awarded book of business (which is based on anticipated pricing and volumes over the life of the applicable program);

• the loss of any of our large original equipment manufacturer (“OEM”) customers (on whom we depend for a substantial portion of our revenues), or the loss of market shares by these customers if we are unable to achieve increased sales to other OEMs or any change in customer demand due to delays in the adoption or enforcement of worldwide emissions regulations;

• our ability to successfully execute cash management and other cost reduction plans, and to realize the anticipated benefits from these plans;

• risks inherent in operating a multi-national company, including economic, exchange rate and political conditions in the countries where we operate or sell our products, adverse changes in trade agreements, tariffs, immigration policies, political stability, and tax and other laws, and potential disruptions of production and supply;

• industrywide strikes, labor disruptions at our facilities or any labor or other economic disruptions at any of our significant customers or suppliers or any of our customers’ other suppliers;

• increases in the costs of raw materials, including our ability to successfully reduce the impact of any such cost increases through materials substitutions, cost reduction initiatives, customer recovery and other methods;

• the negative impact of fuel price volatility on transportation and logistics costs, raw material costs, discretionary purchases of vehicles or aftermarket products and demand for off-highway equipment;

• the cyclical nature of the global vehicle industry, including the performance of the global aftermarket sector and the impact of vehicle parts’ longer product lives;

• costs related to product warranties and other customer satisfaction actions;

• the failure or breach of our information technology systems, including the consequences of any misappropriation, exposure or corruption of sensitive information stored on such systems and the interruption to our business that such failure or breach may cause;

• the impact of consolidation among vehicle parts suppliers and customers on our ability to compete;

• changes in distribution channels or competitive conditions in the markets and countries where we operate, including the impact of increasing competition from lower cost, private-label products on our aftermarket business;

• customer acceptance of new products;

3

• new technologies that reduce the demand for certain of our products or otherwise render them obsolete;

• our ability to introduce new products and technologies that satisfy customers' needs in a timely fashion;

• our ability to realize our business strategy of improving operating performance;

• our ability to successfully integrate any acquisitions that we complete and effectively manage our joint ventures and other third-party relationships;

• changes by the Financial Accounting Standards Board or the Securities and Exchange Commission of authoritative generally accepted accounting principles or policies;

• changes in accounting estimates and assumptions, including changes based on additional information;

• any changes by the International Organization for Standardization (ISO) or other such committees in their certification protocols for processes and products, which may have the effect of delaying or hindering our ability to bring new products to market;

• the impact of the extensive, increasing and changing laws and regulations to which we are subject, including environmental laws and regulations, which may result in our incurrence of environmental liabilities in excess of the amount reserved;

• the potential impairment in the carrying value of our long-lived assets and goodwill or our deferred tax assets;

• potential volatility in our effective tax rate;

• natural disasters, such as earthquakes and flooding, and any resultant disruptions in the supply or production of goods or services to us or by us or in demand by our customers;

• acts of war and/or terrorism, as well as actions taken or to be taken by the United States and other governments as a result of further acts or threats of terrorism, and the impact of these acts on economic, financial and social conditions in the countries where we operate; and

• the timing and occurrence (or non-occurrence) of other transactions, events and circumstances which may be beyond our control.

The risks included here are not exhaustive. Refer to “Part I, Item 1A — Risk Factors” in our annual report on Form 10-K for the year ended December 31, 2016 and "Part II, Item 1A — Risk Factors” of this Form 10-Q for further discussion regarding our exposure to risks. Additionally, new risk factors emerge from time to time and it is not possible for us to predict all such risk factors, nor to assess the impact such risk factors might have on our business or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results. Unless otherwise indicated in this report, the forward-looking statements in this report are made as of the date of this report, and, except as required by law, the Company does not undertake any obligation, and disclaims any obligation, to publicly disclose revisions or updates to any forward-looking statements.

PART I.

FINANCIAL INFORMATION

ITEM 1.FINANCIAL STATEMENTS (UNAUDITED)

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Tenneco Inc.:

We have reviewed the accompanying condensed consolidated balance sheet of Tenneco Inc. and its subsidiaries as of March 31, 2017, and the related condensed consolidated statements of income, comprehensive income, cash flows and changes in shareholders' equity for the three-month periods ended March 31, 2017 and 2016. These interim financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying condensed consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet as of December 31, 2016, and the related consolidated statements of income, comprehensive income, cash flows and changes in shareholders’ equity for the year then ended (not presented herein), and in our report dated February 24, 2017, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet information as of December 31, 2016, is fairly stated, in all material respects, in relation to the condensed consolidated balance sheet from which it has been derived.

The “Report of Independent Registered Public Accounting Firm” included above is not a “report” or “part of a Registration Statement” prepared or certified by an independent accountant within the meaning of Sections 7 and 11 of the Securities Act of 1933, and the accountants’ Section 11 liability does not extend to such report.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(1) Consolidation and Presentation

As you read the accompanying financial statements you should also read our Annual Report on Form 10-K for the year ended December 31, 2016.

In our opinion, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly Tenneco Inc.’s results of operations, comprehensive income, financial position, cash flows, and changes in shareholders’ equity for the periods indicated. We have prepared the unaudited condensed consolidated financial statements pursuant to the rules and regulations of the U.S. Securities and Exchange Commission for interim financial information. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (U.S. GAAP) for annual financial statements.

Our condensed consolidated financial statements include all majority-owned subsidiaries. We carry investments in 20 percent to 50 percent owned companies in which the Company does not have a controlling interest, as equity method investments, at cost plus equity in undistributed earnings since the date of acquisition and cumulative translation adjustments. We have eliminated all intercompany transactions.

Prepayments and Other

Prepayments and other included $126 million and $97 million at March 31, 2017 and December 31, 2016, respectively, for in-process tools and dies that we are building for our original equipment customers.

Accounts Payable

Accounts payable included $88 million and $99 million at March 31, 2017 and December 31, 2016, respectively, for accrued compensation and $30 million and $27 million at March 31, 2017 and December 31, 2016, respectively, for bank overdrafts at our European subsidiaries.

(2) Financial Instruments

The net carrying and estimated fair values of our financial instruments by class at March 31, 2017 and December 31, 2016 were as follows:

	March 31, 2017				December 31, 2016
	Net Carrying Amount		Fair Value		Net Carrying Amount		Fair Value
	(Millions)
Long-term debt (including current maturities)	$	1,409	$	1,418	$	1,297	$	1,311
Instruments with off-balance sheet risk:
Foreign exchange forward contracts:
Asset derivative contracts	—		—		—		—

Asset and Liability Instruments — The fair value of cash and cash equivalents, short and long-term receivables, accounts payable, and short-term debt was considered to be the same as or was not determined to be materially different from the carrying amount.

Long-term Debt — The fair value of our public fixed rate senior notes is based on quoted market prices (level 1). The fair value of our private borrowings under our senior credit facility and other long-term debt instruments is based on the market value of debt with similar maturities, interest rates and risk characteristics (level 2). The fair value of our level 1 debt, as classified in the fair value hierarchy, was $721 million and $725 million at March 31, 2017 and December 31, 2016, respectively. We have classified $682 million and $571 million as level 2 in the fair value hierarchy at March 31, 2017 and December 31, 2016, respectively, since we utilize valuation inputs that are observable both directly and indirectly. We classified the remaining $15 million, consisting of foreign subsidiary debt, as level 3 in the fair value hierarchy at both March 31, 2017 and December 31, 2016.

TENNECO INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS --(Continued)

(Unaudited)

The fair value hierarchy definition prioritizes the inputs used in measuring fair value into the following levels:

Level 1	—	Quoted prices in active markets for identical assets or liabilities.
Level 2	—	Inputs, other than quoted prices in active markets, that are observable either directly or indirectly.
Level 3	—	Unobservable inputs based on our own assumptions.

Foreign Exchange Forward Contracts — We use derivative financial instruments, principally foreign currency forward purchase and sales contracts with terms of less than one year, to hedge our exposure to changes in foreign currency exchange rates. Our primary exposure to changes in foreign currency rates results from intercompany loans made between affiliates to minimize the need for borrowings from third parties. Additionally, we enter into foreign currency forward purchase and sale contracts to mitigate our exposure to changes in exchange rates on certain intercompany and third-party trade receivables and payables. We manage counter-party credit risk by entering into derivative financial instruments with major financial institutions that can be expected to fully perform under the terms of such agreements. We do not enter into derivative financial instruments for speculative purposes. The fair value of our foreign currency forward contracts is based on an internally developed model which incorporates observable inputs including quoted spot rates, forward exchange rates and discounted future expected cash flows utilizing market interest rates with similar quality and maturity characteristics. We record the change in fair value of these foreign exchange forward contracts as part of currency gains (losses) within cost of sales in the consolidated statements of income. The fair value of foreign exchange forward contracts are recorded in prepayments and other current assets or other current liabilities in the consolidated balance sheet. The fair value of our foreign currency forward contracts was a net asset position of less than $1 million at March 31, 2017 and a net liability position of less than $1 million at December 31, 2016, respectively.

The following table summarizes by major currency the notional amounts for foreign currency forward purchase and sale contracts as of March 31, 2017 (all of which mature in 2017):

Guarantees —We have from time to time issued guarantees for the performance of obligations by some of our subsidiaries, and some of our subsidiaries have guaranteed our debt. All of our existing and future material domestic subsidiaries fully and unconditionally guarantee our senior credit facility and our senior notes on a joint and several basis. The arrangement for the senior credit facility is also secured by first-priority liens on substantially all our domestic assets and pledges of up to 66 percent of the stock of certain first-tier foreign subsidiaries. No assets or capital stock secure our senior notes. For additional information, refer to Note 13 of the condensed consolidated financial statements of Tenneco Inc., where we present the Supplemental Guarantor Condensed Consolidating Financial Statements.

We have two performance guarantee agreements in the U.K. between Tenneco Management (Europe) Limited (“TMEL”) and the two Walker Group Retirement Plans, the Walker Group Employee Benefit Plan and the Walker Group Executive Retirement Benefit Plan (the “Walker Plans”), whereby TMEL will guarantee the payment of all current and future pension contributions in the event of a payment default by the sponsoring or participating employers of the Walker Plans. The Walker Plans are comprised of employees from Tenneco Walker (U.K.) Limited and Futaba (U.K.) Limited, formerly our Futaba-Tenneco (U.K.) joint venture. Employer contributions are funded by Tenneco Walker (U.K.) Limited, as the sponsoring employer, and were also funded by Futaba (U.K.) Limited prior to its ceasing, on April 28, 2017, to be an entity in which

(Unaudited)

Tenneco has an equity interest. The performance guarantee agreements are expected to remain in effect until all pension obligations for the Walker Plans’ sponsoring and participating employers have been satisfied. We did not record an additional liability for this performance guarantee since Tenneco Walker (U.K.) Limited, as the sponsoring employer of the Walker Plans, already recognizes 100 percent of the pension obligation calculated based on U.S. GAAP, for all of the Walker Plans’ participating employers on its balance sheet, which was $18 million and $19 million at March 31, 2017 and December 31, 2016, respectively. At March 31, 2017, all pension contributions under the Walker Plans were current for all of the Walker Plans’ sponsoring and participating employers.

In June 2011, we entered into an indemnity agreement between TMEL and Futaba Industrial Co. Ltd. which required Futaba to indemnify TMEL for any cost, loss or liability which TMEL may have incurred under the performance guarantee agreements relating to the Futaba-Tenneco U.K. joint venture. The maximum amount reimbursable by Futaba to TMEL under this indemnity agreement was equal to the amount incurred by TMEL under the performance guarantee agreements multiplied by Futaba’s shareholder ownership percentage of the Futaba-Tenneco U.K. joint venture. At March 31, 2017, the maximum amount reimbursable by Futaba to TMEL was approximately $8 million. Subsequently, on April 28, 2017, Walker Limited sold its equity interest in the Futaba-Tenneco U.K. joint venture entity to Futaba Industrial Co., Ltd. In connection with the closing of that transaction, this indemnity agreement was terminated and accordingly Futaba no longer has any reimbursement obligations thereunder.

We have issued guarantees through letters of credit in connection with some obligations of our affiliates. As of March 31, 2017, we have guaranteed $31 million in letters of credit to support some of our subsidiaries’ insurance arrangements, foreign employee benefit programs, environmental remediation activities and cash management and capital requirements.

Financial Instruments — One of our European subsidiaries receives payment from one of its customers whereby the accounts receivable are satisfied through the delivery of negotiable financial instruments. We may collect these financial instruments before their maturity date by either selling them at a discount or using them to satisfy accounts receivable that have previously been sold to a European bank. Any of these financial instruments which are not sold are classified as other current assets. Such financial instruments held by our European subsidiary totaled zero and less than $1 million at March 31, 2017 and December 31, 2016, respectively.

In certain instances, several of our Chinese subsidiaries receive payment from customers through the receipt of financial instruments on the date the customer payments are due. Several of our Chinese subsidiaries also satisfy vendor payments through the delivery of financial instruments on the date the payments are due. Financial instruments issued to satisfy vendor payables and not redeemed totaled $12 million at both March 31, 2017 and December 31, 2016 and were classified as notes payable. Financial instruments received from original equipment (OE) customers and not redeemed totaled $9 million and $5 million at March 31, 2017 and December 31, 2016, respectively. We classify financial instruments received from our customers as other current assets if issued by a financial institution of our customers or as customer notes and accounts, net if issued by our customer. We classified $9 million and $5 million in other current assets at March 31, 2017 and December 31, 2016, respectively.

The financial instruments received by one of our European subsidiaries and some of our Chinese subsidiaries are drafts drawn that are payable at a future date and, in some cases, are negotiable and/or are guaranteed by the banks of the customers. The use of these instruments for payment follows local commercial practice. Because certain of such financial instruments are guaranteed by our customers’ banks, we believe they represent a lower financial risk than the outstanding accounts receivable that they satisfy which are not guaranteed by a bank.

Supply Chain Financing — Certain of our suppliers participate in supply chain financing programs under which they securitize their accounts receivables from Tenneco. Financial institutions participate in the supply chain financing program on an uncommitted basis and can cease purchasing receivables or drafts from Tenneco's suppliers at any time. If the financial institutions did not continue to purchase receivables or drafts from Tenneco's suppliers under these programs, the participating vendors may have a need to renegotiate their payment terms with Tenneco which in turn would cause our borrowings under our revolving credit facility to increase.

Restricted Cash — Some of our Chinese subsidiaries that issue their own financial instruments to pay vendors are required to maintain a cash balance if they exceed credit limits with the financial institution that guarantees the financial instruments. A restricted cash balance was required at those Chinese subsidiaries for $2 million at both March 31, 2017 and December 31, 2016.

One of our subsidiaries in Brazil is required by law to maintain a cash deposit with the financial institution to guarantee the maximum estimated loss related to a tax audit until a settlement is reached. The cash deposit required was $1 million which has been classified as restricted cash on the Tenneco Inc. consolidated balance sheet at March 31, 2017.

(3) Long-Term Debt and Financing Arrangements

Our financing arrangements are primarily provided by a committed senior secured financing arrangement with a syndicate of banks and other financial institutions. The arrangement is secured by substantially all our domestic assets and pledges of up to 66 percent of the stock of certain first-tier foreign subsidiaries, as well as guarantees by our material domestic subsidiaries.

As of March 31, 2017, the senior credit facility provides us with a total revolving credit facility size of $1,200 million and had a $264 million balance outstanding under the Tranche A Term Facility, both of which will mature on December 8, 2019. Net carrying amount for the balance outstanding under the Tranche A Term Facility including a $1 million debt issuance cost was $263 million as of March 31, 2017. Funds may be borrowed, repaid and re-borrowed under the revolving credit facility without premium or penalty (subject to any customary LIBOR breakage fees). The revolving credit facility is reflected as debt on our balance sheet only if we borrow money under this facility or if we use the facility to make payments for letters of credit. Outstanding letters of credit reduce our availability to borrow revolving loans under the facility. We are required to make quarterly principal payments under the Tranche A Term Facility of $5.625 million through December 31, 2017, $7.5 million beginning March 31, 2018 through September 30, 2019 and a final payment of $195 million is due on December 8, 2019. We have excluded the required payments, within the next twelve months, under the Tranche A Term Facility totaling $24 million from current liabilities as of March 31, 2017, because we have the intent and ability to refinance the obligations on a long-term basis by using our revolving credit facility.

The financial ratios required under the senior credit facility, and the actual ratios we achieved for the first quarter of 2017, are as follows:

	Quarter Ended
	March 31, 2017
	Required	Actual
Leverage Ratio (maximum)	3.50	1.58
Interest Coverage Ratio (minimum)	2.75	15.73

The senior credit facility includes a maximum leverage ratio covenant of 3.50 and a minimum interest coverage ratio of 2.75, in each case through December 8, 2019.

At March 31, 2017, of the $1,200 million available under the revolving credit facility, we had unused borrowing capacity of $783 million with $417 million in outstanding borrowings and no outstanding letters of credit. As of March 31, 2017, our outstanding debt also included (i) $264 million of a term loan which consisted of a $263 million net carrying amount including a $1 million debt issuance cost related to our Tranche A Term Facility which is subject to quarterly principal payments as described above through December 8, 2019, (ii) $225 million of notes which consisted of a $221 million net carrying amount including a $4 million debt issuance cost related to our 5³/₈ percent senior notes due December 15, 2024, (iii) $500 million of notes which consisted of a $492 million net carrying amount including a $8 million debt issuance cost related to our 5 percent senior notes due July 15, 2026 (which were issued on June 13, 2016), and (iv) $126 million of other debt.

(4) Income Taxes

For interim tax reporting we estimate our annual effective tax rate and apply it to our year to date ordinary income. Jurisdictions where no tax benefit can be recognized due to a valuation allowance are excluded from the estimated annual effective tax rate. The impact of including these jurisdictions on the quarterly effective rate calculation could result in a higher or lower effective tax rate during a particular quarter due to the mix and timing of actual earnings versus annual projections. The tax effects of certain unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are excluded from the estimated annual effective tax rate calculation and recognized in the interim period in which they occur.

We reported income tax expense of $34 million in each of the three month periods ended March 31, 2017 and 2016. The tax expense recorded in the first quarter of 2017 included a net tax benefit of $1 million primarily relating to the first quarter 2017 adoption of Accounting Standard Update 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The tax expense recorded in the first quarter of 2016 included a net tax benefit of $3 million primarily relating to tax adjustments to uncertain tax positions and prior year income tax estimates.

We believe it is reasonably possible that up to $17 million in unrecognized tax benefits related to the expiration of foreign statute of limitations and the conclusion of income tax examinations may be recognized within the next twelve months.

(5) Accounts Receivable Securitization

We securitize some of our accounts receivable on a limited recourse basis in the U.S. and Europe. As servicer under these accounts receivable securitization programs, we are responsible for performing all accounts receivable administration functions for these securitized financial assets including collections and processing of customer invoice adjustments. In the U.S., we have an accounts receivable securitization program with three commercial banks comprised of a first priority facility and a second priority facility. We securitize original equipment and aftermarket receivables on a daily basis under the bank program. In April 2017, the U.S. program was amended and extended to April 30, 2019. The first priority facility now provides financing of up to $155 million and the second priority facility, which is subordinated to the first priority facility, now provides up to an additional $25 million of financing. Both facilities monetize accounts receivable generated in the U.S. and Canada that meet certain eligibility requirements, and the second priority facility also monetizes certain accounts receivable generated in the U.S. and Canada that would otherwise be ineligible under the first priority securitization facility. The amount of outstanding third-party investments in our securitized accounts receivable under the U.S. program was $50 million and $30 million at March 31, 2017 and December 31, 2016, respectively.

Each facility contains customary covenants for financings of this type, including restrictions related to liens, payments, mergers or consolidations and amendments to the agreements underlying the receivables pool. Further, each facility may be terminated upon the occurrence of customary events (with customary grace periods, if applicable), including breaches of covenants, failure to maintain certain financial ratios, inaccuracies of representations and warranties, bankruptcy and insolvency events, certain changes in the rate of default or delinquency of the receivables, a change of control and the entry or other enforcement of material judgments. In addition, each facility contains cross-default provisions, where the facility could be terminated in the event of non-payment of other material indebtedness when due and any other event which permits the acceleration of the maturity of material indebtedness.

We also securitize receivables in our European operations with regional banks in Europe. The arrangements to securitize receivables in Europe are provided under seven separate facilities provided by various financial institutions in each of the foreign jurisdictions. The commitments for these arrangements are generally for one year, but some may be canceled with notice 90 days prior to renewal. In some instances, the arrangement provides for cancellation by the applicable financial institution at any time upon notification. The amount of outstanding third-party investments in our securitized accounts receivable in Europe was $209 million and $160 million at March 31, 2017 and December 31, 2016, respectively.

If we were not able to securitize receivables under either the U.S. or European securitization programs, our borrowings under our revolving credit agreement might increase. These accounts receivable securitization programs provide us with access to cash at costs that are generally favorable to alternative sources of financing, and allow us to reduce borrowings under our revolving credit agreement.

In our U.S. accounts receivable securitization program, we transfer a partial interest in a pool of receivables and the interest that we retain is subordinate to the transferred interest. Accordingly, we account for our U.S. 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 ASC Topic 860, “Transfers and Servicing,” to report the transfer of financial assets in their entirety as a sale. The fair value of assets received as proceeds in exchange for the transfer of accounts receivable under our European securitization programs approximates the fair value of such receivables. We recognized $1 million interest expense in each of the three month periods ended March 31, 2017 and 2016 relating to our U.S. securitization program. In addition, we recognized a loss of $1 million in each of the three month periods ended March 31, 2017 and 2016 on the sale of trade accounts receivable in our European accounts receivable securitization programs, representing the discount from book values at which these receivables were sold to our banks. The discount rate varies based on funding costs incurred by our banks, which averaged approximately two percent during the first three months of both 2017 and 2016.

(6) Restructuring and Other Charges

Over the past several years, we have adopted plans to restructure portions of our operations. These plans were approved by our Board of Directors and were designed to reduce operational and administrative overhead costs throughout the business. For the full year 2016, we incurred $36 million in restructuring and related costs including asset write-downs of $6 million, primarily related to manufacturing footprint improvements in North America Ride Performance, headcount reduction and cost improvement initiatives in Europe and China Clean Air, South America and Australia, of which $17 million was recorded in cost of sales, $12 million in SG&A, $1 million in engineering expense, $2 million in other expense and $4 million in depreciation and amortization expense. In the first quarter of 2017, we incurred $15 million in restructuring and related costs, including asset write-downs of $1 million, primarily related to closing a Clean Air Belgian JIT plant in response to the end of production on a customer platform and cost improvement initiatives in Europe, of which $11 million was recorded in cost of sales, $3 million in SG&A and $1 million in depreciation and amortization expense. In the first quarter of 2016, we incurred

16

TENNECO INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS --(Continued)

(Unaudited)

$14 million in restructuring and related costs including asset write-downs of $5 million, primarily related to European cost reduction efforts and headcount reductions in South America, of which $3 million was recorded in cost of sales, $6 million in SG&A, $2 million in other expense and $3 million in depreciation and amortization expense.

Amounts related to activities that are part of our restructuring reserves are as follows:

	December 31, 2016 Restructuring Reserve		2017 Expenses	2017 Cash Payments		Impact of Exchange Rates	March 31, 2017 Restructuring Reserve
	(Millions)
Employee Severance, Termination Benefits and Other Related Costs		$15	13	(6	)	—		$22

On January 31, 2013, we announced our intent to reduce structural costs in Europe by approximately $60 million annually. During the first quarter of 2016, we reached an annualized run rate on this cost reduction initiative of $49 million. With the disposition of the Gijon, Spain plant, which was completed at the end of the first quarter of 2016, the annualized rate essentially reached our target of $55 million at the current exchange rates at that time. In the first quarter of 2017, we incurred $15 million in restructuring and related costs, of which $2 million was related to this initiative. While we are nearing the completion of this initiative, we expect to incur additional restructuring and related costs in 2017 due to certain ongoing matters. For example, we closed the Gijon plant in 2013, but subsequently re-opened it in July 2014 with about half of its prior workforce after the employees' works council successfully filed suit challenging the closure decision. Pursuant to an agreement we entered into with employee representatives, we engaged in a sales process for the facility. In March of 2016, we signed an agreement to transfer ownership of the aftermarket shock absorber manufacturing facility in Gijon to German private equity fund Quantum Capital Partners A.G. (QCP). The transfer to QCP was effective March 31, 2016 and under a three year manufacturing agreement, QCP will also continue as a supplier to Tenneco.

Under the terms of our amended and restated senior credit agreement that took effect on December 8, 2014, we are allowed to exclude up to $150 million in the aggregate of all costs, expenses, fees, fines, penalties, judgments, legal settlements and other amounts associated with any restructuring, litigation, claim, proceeding or investigation related to or undertaken by us or any of our subsidiaries, together with any related provision for taxes, incurred after December 8, 2014 in the calculation of the financial covenant ratios required under our senior credit facility. As of March 31, 2017, we had excluded $96 million of allowable charges relating to restructuring initiatives against the $150 million available under the terms of the senior credit facility.

(7) Environmental Matters, Legal Proceedings and Product Warranties

We are involved in environmental remediation matters, legal proceedings, claims, investigations and warranty obligations. These matters are typically incidental to the conduct of our business and create the potential for contingent losses. We accrue for potential contingent losses when our review of available facts indicates that it is probable a loss has been incurred and the amount of the loss is reasonably estimable. Each quarter we assess our loss contingencies based upon currently available facts, existing technology, presently enacted laws and regulations and taking into consideration the likely effects of inflation and other societal and economic factors and record adjustments to these reserves as required. As an example, we consider all available evidence, including prior experience in remediation of contaminated sites, other companies’ cleanup experiences and data released by the United States Environmental Protection Agency or other organizations when we evaluate our environmental remediation contingencies. All of our loss contingency estimates are subject to revision in future periods based on actual costs or new information. With respect to our environmental liabilities, where future cash flows are fixed or reliably determinable, we have discounted those liabilities. We evaluate recoveries separately from the liability and, when they are assured, recoveries are recorded and reported separately from the associated liability in our consolidated financial statements.

Environmental Matters

We are subject to a variety of environmental and pollution control laws and regulations in all jurisdictions in which we operate. We expense or capitalize, as appropriate, expenditures for ongoing compliance with environmental regulations that relate to current operations. We expense costs related to an existing condition caused by past operations that do not contribute to current or future revenue generation. As of March 31, 2017, we have the obligation to remediate or contribute towards the remediation of certain sites, including one Federal Superfund site. At March 31, 2017, our aggregated estimated share of environmental remediation costs for all these sites on a discounted basis was approximately $15 million, of which $2 million is recorded in other current liabilities and $13 million is recorded in deferred credits and other liabilities in our consolidated

17

TENNECO INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS --(Continued)

(Unaudited)

balance sheet. For those locations where the liability was discounted, the weighted average discount rate used was 2.5 percent. The undiscounted value of the estimated remediation costs was $18 million. Our expected payments of environmental remediation costs are estimated to be approximately $1 million in each year beginning 2017 through 2021 and $13 million in aggregate thereafter.

Based on information known to us, we have established reserves that we believe are adequate for these costs. Although we believe these estimates of remediation costs are reasonable and are based on the latest available information, the costs are estimates and are subject to revision as more information becomes available about the extent of remediation required. At some sites, we expect that other parties will contribute to the remediation costs. In addition, certain environmental statutes provide that our liability could be joint and several, meaning that we could be required to pay in excess of our share of remediation costs. Our understanding of the financial strength of other potentially responsible parties at these sites has been considered, where appropriate, in our determination of our estimated liability. We do not believe that any potential costs associated with our current status as a potentially responsible party in the Federal Superfund site, or as a liable party at the other locations referenced herein, will be material to our consolidated financial position, results of operations, or liquidity.

Antitrust Investigations and Litigation

On March 25, 2014, representatives of the European Commission were at Tenneco GmbH's Edenkoben, Germany administrative facility to gather information in connection with an ongoing global antitrust investigation concerning multiple automotive suppliers. On March 25, 2014, we also received a related subpoena from the U.S. Department of Justice ("DOJ").

On November 5, 2014, the DOJ granted us conditional leniency pursuant to an agreement we entered into under the Antitrust Division's Corporate Leniency Policy. This agreement provides us with important benefits in exchange for our self-reporting of matters to the DOJ and our continuing full cooperation with the DOJ's resulting investigation. For example, the DOJ will not bring any criminal antitrust prosecution against us, nor seek any criminal fines or penalties, in connection with the matters we reported to the DOJ. Additionally, there are limits on our liability related to any follow-on civil antitrust litigation in the U.S. The limits include single rather than treble damages, as well as relief from joint and several antitrust liability with other relevant civil antitrust action defendants. These limits are subject to our satisfying the DOJ and any court presiding over such follow-on civil litigation.

On April 27, 2017, Tenneco received notification from the European Commission (EC) that it has administratively closed its global antitrust inquiry regarding the production, assembly, and supply of complete exhaust systems. No charges against Tenneco or any other competitor were initiated at any time and the EC inquiry is now closed.

Certain other competition agencies are also investigating possible violations of antitrust laws relating to products supplied by our company. We have cooperated and continue to cooperate fully with all of these antitrust investigations, and take other actions to minimize our potential exposure.

Tenneco and certain of its competitors are also currently defendants in civil putative class action litigation in the United States. More related lawsuits may be filed, including in other jurisdictions. Plaintiffs in these cases generally allege that defendants have engaged in anticompetitive conduct, in violation of federal and state laws, relating to the sale of automotive exhaust systems or components thereof. Plaintiffs seek to recover, on behalf of themselves and various purported classes of purchasers, injunctive relief, damages and attorneys’ fees. However, as explained above, because we received conditional leniency from the DOJ, our civil liability in these follow-on actions is limited to single damages and we will not be jointly and severally liable with the other defendants, provided that we have satisfied our obligations under the DOJ leniency agreement and approval is granted by the presiding court.

Antitrust law investigations, civil litigation, and related matters often continue for several years and can result in significant penalties and liability. We intend to vigorously defend the Company and/or take other actions to minimize our potential exposure. In light of the many uncertainties and variables involved, we cannot estimate the ultimate impact that these matters may have on our company. Further, there can be no assurance that the ultimate resolution of these matters will not have a material adverse effect on our consolidated financial position, results of operations or liquidity.

Other Legal Proceedings, Claims and Investigations

We are also from time to time involved in other legal proceedings, claims or investigations. Some of these matters involve allegations of damages against us relating to environmental liabilities (including toxic tort, property damage and remediation), intellectual property matters (including patent, trademark and copyright infringement, and licensing disputes), personal injury claims (including injuries due to product failure, design or warning issues, and other product liability related matters), taxes, unclaimed property, employment matters, and commercial or contractual disputes, sometimes related to acquisitions or divestitures. Additionally, some of these matters involve allegations relating to legal compliance. While we vigorously defend

18

TENNECO INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS --(Continued)

(Unaudited)

ourselves against all of these legal proceedings, claims and investigations and take other actions to minimize our potential exposure, in future periods, we could be subject to cash costs or charges to earnings if any of these matters are resolved on unfavorable terms. Although the ultimate outcome of any legal matter cannot be predicted with certainty, based on current information, including our assessment of the merits of the particular claim, except as described above under "Antitrust Investigations," we do not expect the legal proceedings, claims or investigations currently pending against us will have any material adverse impact on our consolidated financial position, results of operations or liquidity.

In addition, for many years we have been and continue to be subject to lawsuits initiated by claimants alleging health problems as a result of exposure to asbestos. Our current docket of active and inactive cases is less than 500 cases nationwide. A small number of claims have been asserted against one of our subsidiaries by railroad workers alleging exposure to asbestos products in railroad cars. The substantial majority of the remaining claims are related to alleged exposure to asbestos in our automotive products although a significant number of those claims appear also to involve occupational exposures sustained in industries other than automotive. We believe, based on scientific and other evidence, it is unlikely that claimants were exposed to asbestos by our former products and that, in any event, they would not be at increased risk of asbestos-related disease based on their work with these products. Further, many of these cases involve numerous defendants, with the number in some cases exceeding 100 defendants from a variety of industries. Additionally, in many cases the plaintiffs either do not specify any, or specify the jurisdictional minimum, dollar amount for damages. As major asbestos manufacturers and/or users continue to go out of business or file for bankruptcy, we may experience an increased number of these claims. We vigorously defend ourselves against these claims as part of our ordinary course of business. In future periods, we could be subject to cash costs or charges to earnings if any of these matters are resolved unfavorably to us. To date, with respect to claims that have proceeded sufficiently through the judicial process, we have regularly achieved favorable resolutions. Accordingly, we presently believe that these asbestos-related claims will not have a material adverse impact on our future consolidated financial position, results of operations or liquidity.

Warranty Matters

We provide warranties on some of our products. The warranty terms vary but range from one year up to limited lifetime warranties on some of our premium aftermarket products. Provisions for estimated expenses related to product warranty are made at the time products are sold or when specific warranty issues are identified with our products. These estimates are established using historical information about the nature, frequency, and average cost of warranty claims. We actively study trends of our warranty claims and take action to improve product quality and minimize warranty claims. We believe that the warranty reserve is appropriate; however, actual claims incurred could differ from the original estimates, requiring adjustments to the reserve. The reserve is included in both current and long-term liabilities on the balance sheet.

Below is a table that shows the activity in the warranty accrual accounts:

	Three Months Ended March 31,

(8) Earnings Per Share

Earnings per share of common stock outstanding were computed as follows:

	Three Months Ended March 31, 2017		Three Months Ended March 31, 2016
	(Millions Except Share and Per Share Amounts)
Basic earnings per share —
Net income attributable to Tenneco Inc.	$	63	$	57
Weighted Average shares of common stock outstanding	53,856,352		57,115,496
Earnings per share of common stock	$	1.17	$	1.00
Diluted earnings per share —
Net income attributable to Tenneco Inc.	$	63	$	57
Weighted Average shares of common stock outstanding	53,856,352		57,115,496
Effect of dilutive securities:
Restricted stock	145,999		48,603
Stock options	229,408		281,842
Weighted Average shares of common stock outstanding including dilutive securities	54,231,759		57,445,941
Earnings per share of common stock	$	1.16	$	0.99

Options to purchase 834 and 335,826 shares of common stock were outstanding as of March 31, 2017 and 2016, respectively, but not included in the computation of diluted earnings per share respectively, because the options were anti-dilutive.

(9) Common Stock

Equity Plans — We have granted a variety of awards, including common stock, restricted stock, restricted stock units, performance units, stock appreciation rights (“SARs”), and stock options to our directors, officers, and employees.

Accounting Methods — We recorded compensation expense (net of taxes) of less than $1 million in each of the three month periods ended March 31, 2017 and 2016 related to nonqualified stock options as part of our selling, general and administrative expense. This had no impact on basic or diluted earnings per share for each of the three month periods ended March 31, 2017 and 2016.

For employees eligible to retire at the grant date, we immediately expense stock options and restricted stock. If employees become eligible to retire during the vesting period, we accelerate the recognition of any remaining expense associated with their stock options and restricted stock.

As of March 31, 2017, there was no unrecognized compensation cost related to our stock option awards.

Compensation expense for restricted stock, restricted stock units, long-term performance units and SARs (net of taxes) was $6 million and $7 million for the three month periods ended March 31, 2017 and 2016, respectively, and was recorded in selling, general, and administrative expense in our condensed consolidated statements of income.

Cash received from stock option exercises for the three month periods ended March 31, 2017 and 2016 was $6 million and less than $1 million, respectively.

Stock options exercised in the first three months of 2017 and 2016 generated a tax benefit of $2 million and a tax shortfall of less than $1 million, respectively.

There have been no stock options granted since 2015. The total fair value of shares vested from options that were granted prior to 2015 was $2 million for each of the periods ended March 31, 2017 and 2016.

Restricted Stock — The following table reflects the status for all nonvested restricted shares for the period indicated:

	Three Months Ended March 31, 2017
	Shares		Weighted Avg. Grant Date Fair Value

Forfeited	(65,354	)	53.12
Nonvested balance at March 31, 2017	447,602		$	49.25

The fair value of restricted stock grants is usually equal to the average of the high and low trading price of our stock on the date of grant. As of March 31, 2017, approximately $24 million of total unrecognized compensation costs related to restricted stock awards is expected to be recognized over a weighted-average period of approximately 1.7 years. The total fair value of restricted shares vested was $13 million and $7 million at March 31, 2017 and 2016, respectively.

Share Repurchase Program — In January 2015, our Board of Directors approved a share repurchase program, authorizing our company to repurchase up to $350 million of our outstanding common stock over a three year period. In October 2015, our Board of Directors expanded this share repurchase program, authorizing the repurchase of an additional $200 million of the Company's outstanding common stock. In February 2017, our Board of Directors authorized the repurchase of up to $400 million of the Company's outstanding common stock over the next three years. This includes $112 million that remained authorized under earlier repurchase programs. The Company anticipates acquiring the shares through open market or privately negotiated transactions, which will be funded through cash from operations. The repurchase program does not obligate the Company to repurchase shares within any specific time or situations, and opportunities in higher priority areas could affect the cadence of this program. We repurchased 240,000 shares for $16 million through this program in the three months ended March 31, 2017. Since we announced the share repurchase program in January 2015, we have repurchased 8.7 million shares for $454 million through March 31, 2017.

Treasury stock shares including repurchased shares were 11,895,938 and 11,655,938 shares at March 31, 2017 and December 31, 2016, respectively.

Dividends — On February 1, 2017, Tenneco announced the reinstatement of a quarterly dividend program. We expect to pay a quarterly dividend of $0.25 per share on our common stock, representing a planned annual dividend of $1.00 per share. In March 2017, we paid an initial quarterly dividend of $0.25 per share, or $13 million. While we currently expect that comparable quarterly cash dividends will continue to be paid in the future, our dividend program and the payment of future cash dividends under the program are subject to continued capital availability, the judgment of our Board of Directors and our continued compliance with the provisions pertaining to the payment of dividends under our debt agreements.

Long-Term Performance Units, Restricted Stock Units and SARs — Long-term performance units, restricted stock units and SARs are paid in cash and recognized as a liability based upon their fair value. As of March 31, 2017, $33 million of total unrecognized compensation costs is expected to be recognized over a weighted-average period of approximately 2.2 years.

(10) Pension Plans, Postretirement and Other Employee Benefits

Net periodic pension costs and postretirement benefit costs consist of the following components:

	Three Months Ended March 31,
	Pension												Postretirement

Net pension and postretirement costs	$	—		$	3		$	—		$	3		$	2	$	2

For the three months ended March 31, 2017, we made pension contributions of $11 million and $3 million for our domestic and foreign pension plans, respectively. Based on current actuarial estimates, we believe we will be required to contribute approximately $18 million for the remainder of 2017, which includes estimated contributions for the pension buyout referenced below. Pension contributions beyond 2017 will be required, but those amounts will vary based upon many factors including, for example, the performance of our pension fund investments during 2017.

In February 2016, the Company launched a voluntary program to buy out active employees and retirees who had earned benefits in the U.S. pension plans. As of March 31, 2017, this program has been substantially completed with cash payments made from pension plan assets to those who elected to take the buyout. In connection with this program the Company contributed $10 million into the pension trust and recognized a non-cash charge of $6 million in the first quarter of 2017.

We made postretirement contributions of approximately $2 million during the first three months of 2017. Based on current actuarial estimates, we believe we will be required to contribute approximately $8 million for the remainder of 2017.

The assets of some of our pension plans are invested in trusts that permit commingling of the assets of more than one employee benefit plan for investment and administrative purposes. Each of the plans participating in the trust has interests in the net assets of the underlying investment pools of the trusts. The investments for all our pension plans are recorded at estimated fair value, in compliance with the accounting guidance on fair value measurement.

Amounts recognized for pension and postretirement benefits in other comprehensive income for the three months ended March 31, 2017 and 2016 include the following components:

	Three Months Ended March 31,

(11) New Accounting Pronouncements

In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The new guidance improves the presentation of net periodic pension cost and net period postretirement benefit cost. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

In November 2016, the FASB issued Accounting Standard Update 2016-18, Statement of Cash Flows - Restricted Cash (Topic 230) to eliminate diversity in practice in the presentation of restricted cash and restricted cash equivalents in the statement of cash flows. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

In October 2016, the FASB issued Accounting Standard Update 2016-16, Income Taxes - Intra Entity Transfers of Assets Other Than Inventory (Topic 740). The new standard changes the accounting for income taxes when a company transfers certain tangible and intangible assets, such as equipment or intellectual property, between entities in different tax jurisdictions. The new standard does not change the current accounting for the income taxes related to transfers of inventory. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

In March 2016, the FASB issued Accounting Standard Update 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, as part of its initiative to reduce complexity in accounting standards. The areas for simplification in this update involve several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. We adopted this standard for the first quarter of 2017. The impact of the adoption resulted in the following:

• We recorded a tax benefit of $2 million within income tax expense for the three months ended March 31, 2017 related to the excess tax benefit on share-based awards. Prior to adoption, this amount would have been recorded as an addition of additional paid-in capital.

• We no longer reclassify the excess tax benefit from operating activities to financing activities in the statement of cash flows. Cash payments made to the taxing authorities on employees' behalf for withheld shares are presented as financing activities. Tenneco elected to apply this change in presentation retrospectively and thus prior periods have been adjusted. The amounts were not material.

• We excluded the excess tax benefits from the assumed proceeds available to repurchase shares in the computation of our diluted earnings per share for the quarter ended March 31, 2017. The impact was not material.

In February 2016, the FASB issued Accounting Standard Update 2016-02, Leases (Topic 842). The amendments in this update create Topic 842, Leases, and supersede the leases requirements in Topic 840, Leases. Topic 842 specifies the accounting for leases. The objective of Topic 842 is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flow arising from a lease. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2018, and interim periods within those annual periods. We will adopt this amendment on January 1, 2019. We are currently evaluating the potential impact of this new guidance on our consolidated financial statements.

In May 2014, the FASB issued an amendment on revenue recognition. The amendment in this update creates Topic 606, Revenue from Contracts with Customers, and supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance throughout the Industry Topics of the Codification. In addition, the amendment supersedes the cost guidance in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts, and creates new Subtopic 340-40, Other Assets and Deferred Costs-Contracts with Customers. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The FASB approved a one-year deferral of the effective date from January 1, 2017 to January 1, 2018, while allowing for early adoption as of January 1, 2017 for public entities. We will adopt this amendment on January 1, 2018.

The guidance permits the use of either the retrospective or modified retrospective (cumulative effect) transition method and we have not yet selected which transition method we will apply.

We have established a cross-functional coordinated team to implement the guidance related to the recognition of revenue from contracts with customers. We are in the process of assessing our customer contracts, identifying contractual provisions that may result in a change in the timing or the amount of revenue recognized in comparison with current guidance, as well as assessing the enhanced disclosure requirements of the new guidance. Under current guidance we generally recognize revenue when products are shipped and risk of loss has transferred to the customer. Under the proposed requirements, the customized nature of some of our products combined with contractual provisions that provide us with an enforceable right to payment, may require us to recognize revenue prior to the product being shipped to the customer. We are also assessing pricing provisions contained in certain of our customer contracts. Pricing provisions contained in some of our customer contracts represent variable consideration or may provide the customer with a material right, potentially resulting in a different allocation of the transaction price than under current guidance. In addition, we are evaluating how the new guidance may impact our accounting for contractually guaranteed reimbursements related to customer tooling, engineering services and pre-production costs. Under the current applicable guidance, these customer reimbursements are recorded as cost recovery offsets; whereas under the new standard these guaranteed recoveries may represent consideration from contracts with customers and be recorded as revenues. We continue to evaluate the impact this guidance will have on our financial statements.

(12) Segment Information

In connection with the reportable segment changes announced on February 7, 2017, our Clean Air and Ride Performance product lines in India, which have been reported as part of Europe, South America and India segments, will now be reported with their respective product lines in the Asia Pacific segments. Beginning with the first quarter of 2017, we are organized and manage our business along our two major product lines (clean air and ride performance) and three geographic areas (North America; Europe and South America; Asia Pacific), resulting in six operating segments (North America Clean Air, North America Ride Performance, Europe and South America Clean Air, Europe and South America Ride Performance, Asia Pacific Clean Air and Asia Pacific Ride Performance). Within each geographical area, each operating segment manufactures and distributes either clean air or ride performance products primarily for the original equipment and aftermarket industries. Each of the six operating segments constitutes a reportable segment. Costs related to other business activities, primarily corporate headquarter functions, are disclosed separately from the six operating segments as "Other." We evaluate segment performance based primarily on earnings before interest expense, income taxes, and noncontrolling interests. Products are transferred between segments and geographic areas on a basis intended to reflect as nearly as possible the “market value” of the products. Prior period segment information has been revised to reflect our new reporting segments.

ITEM 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

As you read the following review of our financial condition and results of operations, you should also read our condensed consolidated financial statements and related notes beginning on page 6.

Executive Summary

We are one of the world's leading manufacturers of clean air and ride performance products and systems for light vehicle, commercial truck and off-highway applications. We serve both original equipment (OE) vehicle designers and manufacturers and the repair and replacement markets, or aftermarket, globally through leading brands, including Monroe^®, Rancho^®, Clevite^® Elastomers, Axios^™, Kinetic^® and Fric-Rot^™ ride performance products and Walker^®, XNOx^®, Fonos^™, DynoMax^® and Thrush^® clean air products. We serve more than 80 different original equipment manufacturers and commercial truck and off-highway engine manufacturers, and our products are included on nine of the top 10 car models produced for sale in Europe and eight of the top 10 light truck models produced for sale in North America for 2016. Our aftermarket customers are comprised of full-line and specialty warehouse distributors, retailers, jobbers, installer chains and car dealers. As of December 31, 2016, we operated 91 manufacturing facilities worldwide and employed approximately 31,000 people to service our customers' demands.

Factors that continue to be critical to our success include winning new business awards, managing our overall global manufacturing footprint to ensure proper placement and workforce levels in line with business needs, maintaining competitive wages and benefits, maximizing efficiencies in manufacturing processes and reducing overall costs. In addition, our ability to adapt to key industry trends, such as a shift in consumer preferences to other vehicles in response to higher fuel costs and other economic and social factors, increasing technologically sophisticated content, changing aftermarket distribution channels, increasing environmental standards and extended product life of automotive parts, also play a critical role in our success. Other factors that are critical to our success include adjusting to economic challenges such as increases in the cost of raw materials and our ability to successfully reduce the impact of any such cost increases through material substitutions, cost reduction initiatives and other methods.

For the first quarter of 2017, light vehicle production was up three percent in North America, six percent in Europe, seven percent in both China and India and 19 percent in South America compared to the first quarter of 2016. Light vehicle production was down 29 percent in Australia in the first quarter of 2017 when compared to the first quarter of 2016.

As announced on February 7, 2017, we made an organizational change in our reportable segments effective with the first quarter of 2017. Our Clean Air and Ride Performance product lines in India, which had been reported as part of the Europe, South America and India segments, are now reported with their respective product lines in the Asia Pacific segments. Prior period segment information has been revised to reflect our new reporting segments.

Total revenues for the first quarter of 2017 were $2,292 million, up seven percent from $2,136 million in the first quarter of 2016 on strong global light vehicle revenues, driven by both the Clean Air and Ride Performance product lines. Excluding the impact of currency and substrate sales, revenue was up $143 million, or nine percent, from $1,626 million to $1,769 million. The increase in revenues was driven primarily by stronger OE light vehicle volumes mainly in North America, Europe, South America and India, China Ride Performance, new platforms in North America and Europe, and higher commercial truck, off-highway and other vehicle revenues mainly in Europe and China slightly offset by lower off-highway revenue in North America. Higher aftermarket Ride Performance revenues in Europe, South America and Asia Pacific more than offset lower revenues in North America.

Cost of sales (exclusive of depreciation and amortization): Cost of sales for the first quarter of 2017 was $1,925 million, or 84.0 percent of sales, compared to $1,770 million, or 82.9 percent of sales in the first quarter of 2016. The following table lists the primary drivers behind the change in cost of sales ($ millions).

Quarter ended March 31, 2016	$	1,770
Volume and mix	177
Currency exchange rates	(29		)
Restructuring	1
Other costs	6
Quarter ended March 31, 2017	$	1,925

The increase in cost of sales was due to the year-over-year increase in volume, higher other costs, mainly manufacturing, and higher restructuring costs, partially offset by the impact of currency exchange rates.

Gross margin: Revenue less cost of sales for the first quarter of 2017 was $367 million, or 16.0 percent, versus $366 million, or 17.1 percent, in the first quarter of 2016. The effect on gross margin resulting from year-over-year increase in

32

volume was partially offset by higher net material costs, higher other costs, mainly manufacturing, higher restructuring costs and unfavorable currency impact.

Engineering, research and development: Engineering, research and development expense was $39 million in each of the first quarters of 2017 and 2016.

Selling, general and administrative (SG&A): SG&A expense was up $1 million in the first quarter of 2017 at $148 million compared to $147 million in the first quarter of 2016.

Depreciation and amortization: Depreciation and amortization expense was $52 million in the first quarter of 2017, compared to $54 million in the first of quarter of 2016.

Earnings before interest expense, taxes and noncontrolling interests (“EBIT”) was $127 million for the first quarter of 2017, an increase of $3 million when compared to $124 million in the first quarter of the prior year. Higher OE light vehicle volumes in North America, Europe, South America and India, China Ride Performance, new platforms in North America and Europe, higher commercial truck, off-highway and other vehicle revenues mainly in Europe and China and higher aftermarket Ride Performance revenues in Europe, South America and Asia Pacific were partially offset by lower aftermarket Ride Performance and off-highway revenues in North America, the timing of alloy surcharge recoveries in North America, higher manufacturing costs, higher restructuring and related costs and $4 million of negative currency.

Results from Operations

The tables below reflect our revenues for the first quarters of 2017 and 2016. We show the component of our OE revenue represented by substrate sales. While we generally have primary design, engineering and manufacturing responsibility for OE emission control systems, we do not manufacture substrates. Substrates are porous ceramic filters coated with a catalyst - typically, precious metals such as platinum, palladium and rhodium. These are supplied to us by Tier 2 suppliers generally as directed by our OE customers. We generally earn a small margin on these components of the system. As the need for more sophisticated emission control solutions increases to meet more stringent environmental regulations, and as we capture more diesel aftertreatment business, these substrate components have been increasing as a percentage of our revenue. While these substrates dilute our gross margin percentage, they are a necessary component of an emission control system.

Our value-add content in an emission control system includes designing the system to meet environmental regulations through integration of the substrates into the system, maximizing use of thermal energy to heat up the catalyst quickly, efficiently managing airflow to reduce back pressure as the exhaust stream moves past the catalyst, managing the expansion and contraction of the emission control system components due to temperature extremes experienced by an emission control system, using advanced acoustic engineering tools to design the desired exhaust sound, minimizing the opportunity for the fragile components of the substrate to be damaged when we integrate it into the emission control system and reducing unwanted noise, vibration and harshness transmitted through the emission control system.

We present these substrate sales separately in the following table because we believe investors utilize this information to understand the impact of this portion of our revenues on our overall business and because it removes the impact of potentially volatile precious metals pricing from our revenues. While our original equipment customers generally assume the risk of precious metals pricing volatility, it impacts our reported revenues. Presenting revenues that exclude “substrates” used in catalytic converters and diesel particulate filters removes this impact.

Additionally, we present these reconciliations of revenues in order to reflect value-add revenues without the effect of changes in foreign currency rates. We have not reflected any currency impact in the 2016 table since this is the base period for measuring the effects of currency during 2017 on our operations. We believe investors find this information useful in understanding period-to-period comparisons in our revenues.

Clean Air revenue was up $116 million in the first quarter of 2017 compared to the first quarter of 2016 with higher volumes in all segments. In North America, higher volumes drove a $67 million revenue increase due to increased OE light vehicle sales and new platforms offset partially by lower off-highway revenue. Currency had no impact on North American revenues. In the European and South American segment, higher volumes drove a $95 million increase in revenues mainly due to increased OE light vehicle and commercial truck, off-highway and other vehicle sales in the region and new platforms in Europe. Currency had a $22 million unfavorable impact on European and South American revenues. In Asia Pacific, higher volumes of $13 million were mainly driven by increased commercial truck, off-highway and other revenue in China partially offset by lower OE light vehicle revenues in China and Australia. Currency had a $12 million unfavorable impact on Asia Pacific revenues.

Ride Performance revenue was up $40 million in the first quarter of 2017 compared to the first quarter of 2016. In North America, lower volumes of $15 million were driven by lower volumes in commercial truck and aftermarket partially offset by higher OE light vehicle sales and new platforms. Currency had no impact on North American revenues. In the European and South American segment, higher volumes of $30 million were driven by increases in OE light vehicle, commercial truck and off-highway and other and aftermarket sales in the region and new platforms in Europe. Currency had no impact on European and South American revenues. In Asia Pacific, higher volumes of $23 million were mainly driven by increased OE light vehicle volumes in China and India. Currency had a $3 million unfavorable impact on Asia Pacific revenues.

Interest Expense, Net of Interest Capitalized

We reported interest expense in the first quarter of 2017 of $15 million (substantially all in our U.S. operations) net of interest capitalized of $2 million, and $18 million (substantially all in our U.S. operations) net of interest capitalized of $1 million in the first quarter of 2016. The decrease was primarily due to lower interest rates on the bonds refinanced in the second quarter of 2016.

On March 31, 2017, we had $740 million in long-term debt obligations that have fixed interest rates. Of that amount, $500 million is fixed through July 2026, $225 million is fixed through December 2024, and the remainder is fixed from 2016 through 2025. We also have $684 million in long-term debt obligations that are subject to variable interest rates. For more detailed explanations on our debt structure and senior credit facility refer to “Liquidity and Capital Resources — Capitalization” later in this Management’s Discussion and Analysis.

Income Taxes

We reported income tax expense of $34 million in each of the three month periods ended March 31, 2017 and 2016. The tax expense recorded in the first quarter of 2017 included a net tax benefit of $1 million primarily relating to first quarter 2017 adoption of Accounting Standard Update 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The tax expense recorded in the first quarter of 2016 included a net tax benefit of $3 million primarily relating to tax adjustments to uncertain tax positions and prior year income tax estimates.

We believe it is reasonably possible that up to $17 million in unrecognized tax benefits related to the expiration of foreign statute of limitations and the conclusion of income tax examinations may be recognized within the next twelve months.

Restructuring and Other Charges

Over the past several years, we have adopted plans to restructure portions of our operations. These plans were approved by our Board of Directors and were designed to reduce operational and administrative overhead costs throughout the business. For the full year 2016, we incurred $36 million in restructuring and related costs including asset write-downs of $6 million, primarily related to manufacturing footprint improvements in North America Ride Performance, headcount reduction and cost improvement initiatives in Europe and China Clean Air, South America and Australia, of which $17 million was recorded in cost of sales, $12 million in SG&A, $1 million in engineering expense, $2 million in other expense and $4 million in depreciation and amortization expense. In the first quarter of 2017, we incurred $15 million in restructuring and related costs including asset write-downs of $1 million, primarily related to closing a Clean Air Belgian JIT plant in response to the end of production on a customer platform and cost improvement initiatives in Europe, of which $11 million was recorded in cost of sales, $3 million in SG&A and $1 million in depreciation and amortization expense. In the first quarter of 2016, we incurred $14 million in restructuring and related costs including asset write-downs of $5 million, primarily related to European cost reduction efforts and headcount reductions in South America, of which $3 million was recorded in cost of sales, $6 million in SG&A, $2 million in other expense and $3 million in depreciation and amortization expense.

Amounts related to activities that are part of our restructuring reserves are as follows:

	December 31, 2016 Restructuring Reserve		2017 Expenses	2017 Cash Payments	Impact of Exchange Rates	March 31, 2017 Restructuring Reserve
	(Millions)
Employee Severance, Termination Benefits and Other Related Costs	$	15	13	(6)	—	$	22

On January 31, 2013, we announced our intent to reduce structural costs in Europe by approximately $60 million annually. During the first quarter of 2016, we reached an annualized run rate on this cost reduction initiative of $49 million. With the disposition of the Gijon, Spain plant, which was completed at the end of the first quarter of 2016, the annualized rate essentially reached our target of $55 million at the current exchange rates at that time. In the first quarter of 2017, we incurred $15 million in restructuring and related costs, of which $2 million was related to this initiative. While we are nearing the completion of this initiative, we expect to incur additional restructuring and related costs in 2017 due to certain ongoing matters. For example, we closed the Gijon plant in 2013, but subsequently re-opened it in July 2014 with about half of its prior workforce after the employees' works council successfully filed suit challenging the closure decision. Pursuant to an agreement we entered into with employee representatives, we engaged in a sales process for the facility. In March of 2016, we signed an agreement to transfer ownership of the aftermarket shock absorber manufacturing facility in Gijon to German private equity fund Quantum Capital Partners A.G. (QCP). The transfer to QCP was effective March 31, 2016 and under a three year manufacturing agreement, QCP will also continue as a supplier to Tenneco.

38

Under the terms of our amended and restated senior credit agreement that took effect on December 8, 2014, we are allowed to exclude up to $150 million in the aggregate of all costs, expenses, fees, fines, penalties, judgments, legal settlements and other amounts associated with any restructuring, litigation, claim, proceeding or investigation related to or undertaken by us or any of our subsidiaries, together with any related provision for taxes, incurred after December 8, 2014 in the calculation of the financial covenant ratios required under our senior credit facility. As of March 31, 2017, we had excluded $96 million of allowable charges relating to restructuring initiatives against the $150 million available under the terms of the senior credit facility.

Earnings Per Share

We reported net income attributable to Tenneco Inc. of $63 million or $1.16 per diluted common share for the first quarter of 2017. Included in the results for the first quarter of 2017 was positive impact from net tax benefit which was more than offset by negative impacts from expenses related to our restructuring activities and charges related to pension derisking and the acceleration of restricted stock vesting. The total impact of these items decreased earnings per diluted share by $0.37. We reported net income attributable to Tenneco Inc. of $57 million or $0.99 per diluted common share for the first quarter of 2016. Included in the results for the first quarter of 2016 were negative impacts from expenses related to our restructuring activities offset partially by net tax benefits. The total impact of these items decreased earnings per diluted share by $0.18.

Dividends on Common Stock

On February 1, 2017, Tenneco announced the reinstatement of a quarterly dividend program. We expect to pay a quarterly dividend of $0.25 per share on our common stock, representing a planned annual dividend of $1.00 per share. In March 2017, we paid an initial quarterly dividend of $0.25 per share, or $13 million. While we currently expect that comparable quarterly cash dividends will continue to be paid in the future, our dividend program and the payment of future cash dividends under the program are subject to continued capital availability, the judgment of our Board of Directors and our continued compliance with the provisions pertaining to the payment of dividends under our debt agreements.

Operating Activities

For the first quarter of 2017, operating activities used $9 million in cash compared to $29 million in cash used during last year’s first quarter, driven by higher earnings and continued strong performance in accounts receivables, payables and inventories. For the first quarter of 2017, cash used for working capital was $158 million versus $164 million of cash used for working capital in the first quarter of 2016. Receivables were a use of cash of $137 million in the first quarter of 2017 compared to a use of cash of $160 million in the prior year’s first quarter. Inventory represented a cash outflow of $45 million for the first quarter of 2017 and a cash outflow of $51 million during the first quarter of 2016. Accounts payable provided $91 million of cash for the quarter ended March 31, 2017 compared to $56 million of cash provided for the quarter ended March 31, 2016. Cash taxes were $15 million in the first quarter of 2017 compared to $21 million in the prior year's first quarter.

Investing Activities

Cash used for investing activities was $107 million in the first quarter of 2017 compared to cash used of $74 million in the same period a year ago. Cash payments for plant, property and equipment were $103 million in the first quarter of 2017 versus payments of $68 million in the first quarter of 2016. Cash payments for software-related intangible assets were $6 million in each of the first quarters of 2017 and 2016. Changes in restricted cash were a use of cash of $1 million in each of the first quarters of 2017 and 2016.

Financing Activities

Cash flow from financing activities was an inflow of $102 million for the quarter ended March 31, 2017, compared to an inflow of $183 million for the quarter ended March 31, 2016. We repurchased 240,000 shares of our outstanding common stock for $16 million at an average price of $64.81 per share during the first quarter of 2017 and 360,000 shares of our outstanding

39

common stock for $16 million at an average price of $45.09 per share during the first quarter of 2016. Since announcing our share repurchase program in 2015, we have repurchased a total of approximately 8.7 million shares for $454 million, representing 14 percent of the shares outstanding at that time. In February 2017, the Board authorized the repurchase of up to $400 million of common stock over the next three years. This amount includes the $112 million that remained authorized under earlier repurchase programs. As of March 31, 2017, we had $384 million remaining on the share repurchase authorization. On February 1, 2017, our Board of Directors declared a cash dividend of $0.25, payable on March 23, 2017 to shareholders of record as of March 7, 2017. In March 2017, we paid an initial quarterly dividend of $0.25 per share, or $13 million.

Borrowings under our revolving credit facility were $417 million at March 31, 2017 and $288 million at March 31, 2016. At March 31, 2017, there was $50 million borrowing under the U.S. accounts receivable securitization program, whereas at March 31, 2016, there was $30 million outstanding.

Outlook

In the second quarter 2017, we expect year-over-year revenue growth of approximately five percent on a constant currency basis, outpacing estimated light vehicle industry production growth by four percentage points. Based on current exchange rates, we anticipate a two percent currency headwind in the second quarter.

Our organic revenue growth is expected to be driven by Clean Air and Ride Performance content on top-selling light vehicle platforms globally, continued strong commercial truck growth, and a steady contribution from the global aftermarket.

We also reaffirm our full-year revenue growth outlook announced in January 2017. On a constant currency basis, we expect year-over-year growth of five percent, outpacing estimated light vehicle industry growth by four percentage points. We also expect annual margin improvement in 2017.

Tenneco's revenue projections are based on the type of information set forth under "Outlook" in Item 7 - "Management's Discussion and Analysis of Financial Condition and Results of Operations" as set forth in Tenneco's Annual Report on Form 10-K for the year ended December 31, 2016. Please see that disclosure for further information. Additionally, revenue assumptions for the second quarter and full year 2017 are based on current and projected customer production schedules as well as aggregate industry production, which includes IHS Automotive April 2017 global light vehicle production forecasts, Power Systems Research (PSR) April 2017 forecast for global commercial truck and buses, PSR off-highway engine production in North America and Europe and Tenneco estimates. Unless otherwise indicated, our revenue estimate methodology does not attempt to forecast currency fluctuation, and accordingly reflects constant currency. See “Cautionary Statement for Purposes of the ‘Safe Harbor’ Provisions of the Private Securities Litigation Reform Act of 1995” and Item 1A, “Risk Factors.”

Critical Accounting Policies

We prepare our condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America. Preparing our condensed consolidated financial statements in accordance with generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The following paragraphs include a discussion of some critical areas where estimates are required.

Revenue Recognition

We recognize revenue for sales to our original equipment and aftermarket customers when title and risk of loss passes to the customers under the terms of our arrangements with those customers, which is usually at the time of shipment from our plants or distribution centers. Generally, in connection with the sale of exhaust systems to certain original equipment manufacturers, we purchase catalytic converters and diesel particulate filters or components thereof including precious metals (“substrates”) on behalf of our customers which are used in the assembled system. These substrates are included in our inventory and “passed through” to the customer at our cost, plus a small margin, since we take title to the inventory and are responsible for both the delivery and quality of the finished product. Revenues recognized for substrate sales were $547 millionand $510 million for the first three months of 2017 and 2016, respectively. For our aftermarket customers, we provide for promotional incentives and returns at the time of sale. Estimates are based upon the terms of the incentives and historical experience with returns. Certain taxes assessed by governmental authorities on revenue producing transactions, such as value added taxes, are excluded from revenue and recorded on a net basis. Shipping and handling costs billed to customers are included in revenues and the related costs are included in cost of sales in our condensed consolidated statements of income.

Warranty Reserves

Where we have offered product warranty, we also provide for warranty costs. Provisions for estimated expenses related to product warranty are made at the time products are sold or when specific warranty issues are identified with our products. These estimates are established using historical information about the nature, frequency, and average cost of warranty claims

40

and upon specific warranty issues as they arise. The warranty terms vary but range from one year up to limited lifetime warranties on some of our premium aftermarket products. We actively study trends of our warranty claims and take action to improve product quality and minimize warranty claims. While we have not experienced any material differences between these estimates and our actual costs, it is reasonably possible that future warranty issues could arise that could have a significant impact on our condensed consolidated financial statements.

Pre-production Design and Development and Tooling Assets

We expense pre-production design and development costs as incurred unless we have a contractual guarantee for reimbursement from the original equipment customer. Unbilled pre-production design and development costs recorded in prepayments and other and long-term receivables totaled $22 million at both March 31, 2017 and December 31, 2016. In addition, plant, property and equipment included $63 million and $62 million at March 31, 2017 and December 31, 2016, respectively, for original equipment tools and dies that we own, and prepayments and other included $125 million and $97 million at March 31, 2017 and December 31, 2016, respectively, for in-process tools and dies that we are building for our original equipment customers.

Income Taxes

We recognize deferred tax assets and liabilities on the basis of the future tax consequences attributable to temporary differences that exist between the financial statement carrying value of assets and liabilities and their respective tax values, and net operating losses ("NOL") and tax credit carryforwards on a taxing jurisdiction basis. We measure deferred tax assets and liabilities using enacted tax rates that will apply in the years in which we expect the temporary differences to be recovered or paid.

We evaluate our deferred income taxes quarterly to determine if valuation allowances are required or should be adjusted. U.S. GAAP requires that companies assess whether valuation allowances should be established against their deferred tax assets based on consideration of all available evidence, both positive and negative, using a "more likely than not" standard. This assessment considers, among other matters, the nature, frequency and amount of recent losses, the duration of statutory carryforward periods, and tax planning strategies. In making such judgments, significant weight is given to evidence that can be objectively verified.

Valuation allowances are established for deferred tax assets based on a “more likely than not” threshold. The ability to realize deferred tax assets depends on our ability to generate sufficient taxable income within the carryforward periods provided for in the tax law for each tax jurisdiction. We have considered the following possible sources of taxable income when assessing the realization of our deferred tax assets:

• Future reversals of existing taxable temporary differences;

• Taxable income or loss, based on recent results, exclusive of reversing temporary differences and carryforwards;

• Tax-planning strategies; and

• Taxable income in prior carryback years if carryback is permitted under the relevant tax law.

The valuation allowances recorded against deferred tax assets in certain foreign jurisdictions will impact our provision for income taxes until the valuation allowances are released. Our provision for income taxes will include no tax benefit for losses incurred and no tax expense with respect to income generated in these jurisdictions until the respective valuation allowance is eliminated.

For interim tax reporting we estimate our annual effective tax rate and apply it to our year to date ordinary income. Jurisdictions where no tax benefit can be recognized due to a valuation allowance are excluded from the estimated annual effective tax rate. The impact of including these jurisdictions on the quarterly effective rate calculation could result in a higher or lower effective tax rate during a particular quarter due to the mix and timing of actual earnings versus annual projections. The tax effects of certain unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are excluded from the estimated annual effective tax rate calculation and recognized in the interim period in which they occur.

Goodwill, net

We evaluate goodwill for impairment as of October 31st each year, or more frequently if events indicate it is warranted. The goodwill impairment test consists of a two-step process. In step one, we compare the estimated fair value of our reporting units with goodwill to the carrying value of the unit’s assets and liabilities to determine if impairment exists within the recorded balance of goodwill. We estimate the fair value of each reporting unit using the income approach which is based on the present value of estimated future cash flows. The income approach is dependent on a number of factors, including estimates of market trends, forecasted revenues and expenses, capital expenditures, weighted average cost of capital and other variables. A separate discount rate derived by a combination of published sources, internal estimates and weighted based on our debt and equity

41

structure, was used to calculate the discounted cash flows for each of our reporting units. These estimates are based on assumptions that we believe to be reasonable, but which are inherently uncertain and outside of the control of management. If the carrying value of the reporting unit is higher than its fair value, there is an indication that impairment may exist which requires step two to be performed to measure the amount of the impairment loss. The amount of impairment is determined by comparing the implied fair value of a reporting unit’s goodwill to its carrying value.

The estimated fair value of each of our reporting units exceeded the carrying value of their assets and liabilities as October 31, 2016.

Pension and Other Postretirement Benefits

We have various defined benefit pension plans that cover some of our employees. We also have postretirement health care and life insurance plans that cover some of our domestic employees. Our pension and postretirement health care and life insurance expenses and valuations are dependent on assumptions used by our actuaries in calculating those amounts. These assumptions include discount rates, health care cost trend rates, long-term return on plan assets, retirement rates, mortality rates and other factors. Health care cost trend rate assumptions are developed based on historical cost data and an assessment of likely long-term trends. Retirement rates are based primarily on actual plan experience while mortality rates are based upon the general population experience which is not expected to differ materially from our experience.

Our approach to establishing the discount rate assumption for both our domestic and foreign plans is generally based on the yield on high-quality corporate fixed-income investments. At the end of each year, the discount rate is determined using the results of bond yield curve models based on a portfolio of high quality bonds matching the notional cash inflows with the expected benefit payments for each significant benefit plan. Based on this approach, we lowered the weighted average discount rate for all our pension plans to 3.3 percent in 2017 from 3.9 percent in 2016. The discount rate for postretirement benefits was lowered to 4.2 percent in 2017 from 4.3 percent in 2016.

Our approach to determining expected return on plan asset assumptions evaluates both historical returns as well as estimates of future returns, and is adjusted for any expected changes in the long-term outlook for the equity and fixed income markets. As a result, our estimate of the weighted average long-term rate of return on plan assets for all of our pension plans was lowered to 6.1 percent for 2017 from 6.6 percent for 2016.

Except in the U.K., our pension plans generally do not require employee contributions. Our policy is to fund our pension plans in accordance with applicable U.S. and foreign government regulations and to make additional payments as funds are available to achieve full funding of the accumulated benefit obligation. As of March 31, 2017, all legal funding requirements have been met.

General. Short-term debt, which includes maturities classified as current, borrowings by foreign subsidiaries, and borrowings under our U.S. accounts receivable securitization program, were $113 million and $90 million as of March 31, 2017 and December 31, 2016, respectively. Borrowings under our revolving credit facilities, which are classified as long-term debt, were $417 million and $300 million at March 31, 2017 and December 31, 2016, respectively.

The 2017 year-to-date increase in Tenneco Inc. shareholders' equity primarily resulted from net income attributable to Tenneco Inc. of $63 million, a $7 million increase related to pension and postretirement benefits, a $6 million increase in

42

premium on common stock and other capital surplus relating to common stock issued pursuant to benefit plans, and a $21 million increase caused by the impact of changes in foreign exchange rates on the translation of financial statements of our foreign subsidiaries into U.S. dollars, partially offset by a $13 million decrease related to cash dividends declared and a $16 million increase in treasury stock as a result of purchases of common stock under our share purchase program.

Overview. Our financing arrangements are primarily provided by a committed senior secured financing arrangement with a syndicate of banks and other financial institutions. The arrangement is secured by substantially all our domestic assets and pledges of up to 66 percent of the stock of certain first-tier foreign subsidiaries, as well as guarantees by our material domestic subsidiaries.

As of March 31, 2017, the senior credit facility provides us with a total revolving credit facility size of $1,200 million and had a $264 million balance outstanding under the Tranche A Term Facility, both of which will mature on December 8, 2019. Net carrying amount for the balance outstanding under the Tranche A Term Facility including a $1 million debt issuance cost was $263 million. Funds may be borrowed, repaid and re-borrowed under the revolving credit facility without premium or penalty (subject to any customary LIBOR breakage fees). The revolving credit facility is reflected as debt on our balance sheet only if we borrow money under this facility or if we use the facility to make payments for letters of credit. Outstanding letters of credit reduce our availability to borrow revolving loans under the facility. We are required to make quarterly principal payments under the Tranche A Term Facility of $5.625 million through December 31, 2017, $7.5 million beginning March 31, 2018 through September 30, 2019 and a final payment of $195 million is due on December 8, 2019. We have excluded the required payments, within the next twelve months, under the Tranche A Term Facility totaling $24 million from current liabilities as of March 31, 2017, because we have the intent and ability to refinance the obligations on a long-term basis by using our revolving credit facility.

At March 31, 2017, of the $1,200 million available under the revolving credit facility, we had unused borrowing capacity of $783 million with $417 million in outstanding borrowings and no outstanding letters of credit. As of March 31, 2017, our outstanding debt also included (i) $264 million of a term loan which consisted of a $263 million net carrying amount including a $1 million debt issuance cost related to our Tranche A Term Facility which is subject to quarterly principal payments as described above through December 8, 2019, (ii) $225 million of notes which consisted of a $221 million net carrying amount including a $4 million debt issuance cost related to our 5³/₈ percent senior notes due December 15, 2024, (iii) $500 million of notes which consisted of a $492 million net carrying amount including a $8 million debt issuance cost related to our 5 percent senior notes due July 15, 2026 (which were issued on June 13, 2016), and (iv) $126 million of other debt.

We monitor market conditions with respect to the potential refinancing of our outstanding debt obligations, including our senior secured credit facility and senior notes. Depending on market and other conditions, we may seek to refinance our debt obligations from time to time. We cannot make any assurance, however, that any refinancing will be completed.

Senior Credit Facility — Interest Rates and Fees. Beginning December 8, 2014, our Tranche A Term Facility and revolving credit facility bear interest at an annual rate equal to, at our option, either (i) London Interbank Offered Rate (“LIBOR”) plus a margin of 175 basis points, or (ii) a rate consisting of the greater of (a) the JPMorgan Chase prime rate plus a margin of 75 basis points, (b) the Federal Funds rate plus 50 basis points plus a margin of 75 basis points, and (c) one month LIBOR plus 100 basis points plus a margin of 75 basis points. The margin we pay on these borrowings will be increased by a total of 25 basis points above the original margin following each fiscal quarter for which our consolidated net leverage ratio is equal to or greater than 2.25 and less than 3.25, and will be increased by a total of 50 basis points above the original margin following each fiscal quarter for which our consolidated net leverage ratio is equal to or greater than 3.25. In addition, the margin we pay on these borrowings will be reduced by a total of 25 basis points below the original margin if our consolidated net leverage ratio is less than 1.25. We also pay a commitment fee equal to 30 basis points that will be reduced to 25 basis points or increased to up to 40 basis points depending on consolidated net leverage ratio changes as set forth in the senior credit facility.

Senior Credit Facility — Other Terms and Conditions. Our senior credit facility requires that we maintain financial ratios equal to or better than the following consolidated net leverage ratio (consolidated indebtedness net of cash divided by consolidated EBITDA, as defined in the senior credit facility agreement), and consolidated interest coverage ratio (consolidated EBITDA divided by consolidated interest expense, as defined in the senior credit facility agreement) at the end of each period indicated. Failure to maintain these ratios will result in a default under our senior credit facility. The financial ratios required under the senior credit facility and the actual ratios we achieved for the first quarter of 2017, are as follows:

	Quarter Ended
	March 31, 2017
	Required	Actual
Leverage Ratio (maximum)	3.50	1.58
Interest Coverage Ratio (minimum)	2.75	15.73

43

The senior credit facility includes a maximum leverage ratio covenant of 3.50 and a minimum interest coverage ratio of 2.75, in each case through December 8, 2019.

The covenants in our senior credit facility agreement generally prohibit us from repaying or refinancing our senior notes. So long as no default existed, we would, however, under our senior credit facility agreement, be permitted to repay or refinance our senior notes (i) with the net cash proceeds of permitted refinancing indebtedness (as defined in the senior credit facility agreement) or with the net cash proceeds of our common stock, in each case issued within 180 days prior to such repayment; (ii) with the net cash proceeds of the incremental facilities (as defined in the senior credit facility agreement) and certain indebtedness incurred by our foreign subsidiaries; (iii) with the proceeds of the revolving loans (as defined in the senior credit facility agreement); (iv) with the cash generated by our operations; (v) in an amount equal to the net cash proceeds of qualified capital stock (as defined in the senior credit facility agreement) issued by us after December 8, 2014; and (vi) in exchange for permitted refinancing indebtedness or in exchange for shares of our common stock; provided that such purchases are capped as follows (with respect to clauses (iii), (iv) and (v) based on a pro forma consolidated leverage ratio after giving effect to such purchase, cancellation or redemption):

Pro forma Consolidated Leverage Ratio	Aggregate Senior Note Maximum Amount
	(Millions)
Greater than or equal to 3.0x	$	20
Greater than or equal to 2.5x	$	100
Greater than or equal to 2.0x	$	200
Less than 2.0x	no limit

Although the senior credit facility agreement would permit us to repay or refinance our senior notes under the conditions described above, any repayment or refinancing of our outstanding notes would be subject to market conditions and either the voluntary participation of note holders or our ability to redeem the notes under the terms of the applicable note indenture. For example, while the senior credit facility agreement would allow us to repay our outstanding notes via a direct exchange of the notes for either permitted refinancing indebtedness or for shares of our common stock, we do not, under the terms of the agreements governing our outstanding notes, have the right to refinance the notes via any type of direct exchange.

The senior credit facility agreement also contains other restrictions on our operations that are customary for similar facilities, including limitations on: (i) incurring additional liens; (ii) sale and leaseback transactions (except for the permitted transactions as described in the senior credit facility agreement); (iii) liquidations and dissolutions; (iv) incurring additional indebtedness or guarantees; (v) investments and acquisitions; (vi) dividends and share repurchases; (vii) mergers and consolidations; and (viii) refinancing of the senior notes. Compliance with these requirements and restrictions is a condition for any incremental borrowings under the senior credit facility agreement and failure to meet these requirements enables the lenders to require repayment of any outstanding loans.

As of March 31, 2017, we were in compliance with all the financial covenants and operational restrictions of the senior credit facility. Our senior credit facility does not contain any terms that could accelerate payment of the facility or affect pricing under the facility as a result of a credit rating agency downgrade.

Senior Notes. As of March 31, 2017, our outstanding senior notes included $225 million of 5³/8 percent senior notes due December 15, 2024 which consisted of $221 million net carrying amount including a $4 million debt issuance cost and $500 million of 5 percent senior notes due July 15, 2026 which consisted of $492 million net carrying amount including a $8 million debt issuance cost. Under the indentures governing the remaining notes, we are permitted to redeem some or all of the remaining senior notes at specified prices that decline to par over a specified period, (a) on or after July 15, 2021, in case of the senior notes due 2026, and (b) on or after December 15, 2019, in the case of the senior notes due 2024. In addition, the notes may also be redeemed in whole or in part at a redemption price generally equal to 100 percent of the principal amount thereof plus a premium based on the present values of the remaining payments due to the note holders. Further, the indentures governing the notes also permit us to redeem up to 35 percent of the senior notes with the proceeds of certain equity offerings, (a) on or before July 15, 2019 at a redemption price equal to 105 percent, in case of the senior notes due 2026 and (b) on or before December 15, 2017 at a redemption price equal to 105.375 percent, in case of the senior notes due 2024. If we sell certain of our assets or experience specified kinds of changes in control, we must offer to repurchase the notes due 2026 and 2024 at 101 percent of the principal amount thereof plus accrued and unpaid interest.

Our senior notes due, respectively, December 15, 2024 and July 15, 2026 contain covenants that will, among other things, limit our ability to create liens, and enter into sale and leaseback transactions. Our senior notes due 2024 also require that, as a condition precedent to incurring certain types of indebtedness not otherwise permitted, our consolidated fixed charge coverage ratio, as calculated on a pro forma basis, be greater than 2.00, as well as containing restrictions on our operations, including limitations on: (i) incurring additional indebtedness; (ii) dividends; (iii) distributions and stock repurchases; (iv) investments; (v) asset sales and (vi) mergers and consolidations. Subject to limited exceptions, all of our existing and future material

44

domestic wholly owned subsidiaries fully and unconditionally guarantee our senior notes on a joint and several basis. There are no significant restrictions on the ability of the subsidiaries that have guaranteed these notes to make distributions to us. As of March 31, 2017, we were in compliance with the covenants and restrictions of these indentures.

Accounts Receivable Securitization. We securitize some of our accounts receivable on a limited recourse basis in the U.S. and Europe. As servicer under these accounts receivable securitization programs, we are responsible for performing all accounts receivable administration functions for these securitized financial assets including collections and processing of customer invoice adjustments. In the U.S., we have an accounts receivable securitization program with three commercial banks comprised of a first priority facility and a second priority facility. We securitize original equipment and aftermarket receivables on a daily basis under the bank program. In April 2017, the U.S. program was amended and extended to April 30, 2019. The first priority facility now provides financing of up to $155 million and the second priority facility, which is subordinated to the first priority facility, now provides up to an additional $25 million of financing. Both facilities monetize accounts receivable generated in the U.S. and Canada that meet certain eligibility requirements, and the second priority facility also monetizes certain accounts receivable generated in the U.S. and Canada that would otherwise be ineligible under the first priority securitization facility. The amount of outstanding third-party investments in our securitized accounts receivable under the U.S. program was $50 million and $30 million at March 31, 2017 and December 31, 2016, respectively.

Each facility contains customary covenants for financings of this type, including restrictions related to liens, payments, mergers or consolidations and amendments to the agreements underlying the receivables pool. Further, each facility may be terminated upon the occurrence of customary events (with customary grace periods, if applicable), including breaches of covenants, failure to maintain certain financial ratios, inaccuracies of representations and warranties, bankruptcy and insolvency events, certain changes in the rate of default or delinquency of the receivables, a change of control and the entry or other enforcement of material judgments. In addition, each facility contains cross-default provisions, where the facility could be terminated in the event of non-payment of other material indebtedness when due and any other event which permits the acceleration of the maturity of material indebtedness.

We also securitize receivables in our European operations with regional banks in Europe. The arrangements to securitize receivables in Europe are provided under seven separate facilities provided by various financial institutions in each of the foreign jurisdictions. The commitments for these arrangements are generally for one year, but some may be canceled with notice 90 days prior to renewal. In some instances, the arrangement provides for cancellation by the applicable financial institution at any time upon notification. The amount of outstanding third-party investments in our securitized accounts receivable in Europe was $209 million and $160 million at March 31, 2017 and December 31, 2016, respectively.

If we were not able to securitize receivables under either the U.S. or European securitization programs, our borrowings under our revolving credit agreement might increase. These accounts receivable securitization programs provide us with access to cash at costs that are generally favorable to alternative sources of financing, and allow us to reduce borrowings under our revolving credit agreement.

In our U.S. accounts receivable securitization program, we transfer a partial interest in a pool of receivables and the interest that we retain is subordinate to the transferred interest. Accordingly, we account for our U.S. 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 ASC Topic 860, “Transfers and Servicing,” to report the transfer of financial assets in their entirety as a sale. The fair value of assets received as proceeds in exchange for the transfer of accounts receivable under our European securitization programs approximates the fair value of such receivables. We recognized $1 million interest expense in each of the three month periods ended March 31, 2017 and 2016 relating to our U.S. securitization program. In addition, we recognized a loss of $1 million in each of the three month periods ended March 31, 2017 and 2016, on the sale of trade accounts receivable in our European accounts receivable securitization programs, representing the discount from book values at which these receivables were sold to our banks. The discount rate varies based on funding costs incurred by our banks, which averaged approximately two percent during the first three months of both 2017 and 2016.

Financial Instruments. One of our European subsidiaries receives payment from one of its customers whereby the accounts receivable are satisfied through the delivery of negotiable financial instruments. We may collect these financial instruments before their maturity date by either selling them at a discount or using them to satisfy accounts receivable that have previously been sold to a European bank. Any of these financial instruments which are not sold are classified as other current assets. Such financial instruments held by our European subsidiary totaled zero and less than $1 million as of March 31, 2017 and December 31, 2016, respectively.

In certain instances, several of our Chinese subsidiaries receive payment from customers through the receipt of financial instruments on the date the customer payments are due. Several of our Chinese subsidiaries also satisfy vendor payments through the delivery of financial instruments on the date the payments are due. Financial instruments issued to satisfy vendor payables and not redeemed totaled $12 million at both March 31, 2017 and December 31, 2016 and were classified as notes payable. Financial instruments received from OE customers and not redeemed totaled $9 million and $5 million at March 31, 2017 and December 31, 2016, respectively. We classify financial instruments received from our customers as other current

45

assets if issued by a financial institution of our customers or as customer notes and accounts, net if issued by our customer. We classified $9 million and $5 million in other current assets at March 31, 2017 and December 31, 2016, respectively.

The financial instruments received by one of our European subsidiaries and some of our Chinese subsidiaries are drafts drawn that are payable at a future date and, in some cases, are negotiable and/or are guaranteed by the banks of the customers. The use of these instruments for payment follows local commercial practice. Because certain of such financial instruments are guaranteed by our customers’ banks, we believe they represent a lower financial risk than the outstanding accounts receivable that they satisfy which are not guaranteed by a bank.

Supply Chain Financing. Certain of our suppliers in the U.S. participate in a supply chain financing programs under which they securitize their accounts receivables from Tenneco. Financial institutions participate in the supply chain financing program on an uncommitted basis and can cease purchasing receivables from Tenneco's suppliers at any time. If the financial institutions did not continue to purchase receivables from Tenneco's suppliers under these programs, the participating vendors may have a need to renegotiate their payment terms with Tenneco which in turn would cause our borrowings under our revolving credit facility to increase.

Capital Requirements. We believe that cash flows from operations, combined with our cash on hand, subject to any applicable withholding taxes upon repatriation of cash balances from our foreign operations where most of our cash balances are located, and available borrowing capacity described above, assuming that we maintain compliance with the financial covenants and other requirements of our senior credit facility agreement, will be sufficient to meet our future capital requirements, including debt amortization, capital expenditures, pension contributions, and other operational requirements, for the following year. Our ability to meet the financial covenants depends upon a number of operational and economic factors, many of which are beyond our control. In the event that we are unable to meet these financial covenants, we would consider several options to meet our cash flow needs. Such actions include additional restructuring initiatives and other cost reductions, sales of assets, reductions to working capital and capital spending, issuance of equity and other alternatives to enhance our financial and operating position. Should we be required to implement any of these actions to meet our cash flow needs, we believe we can do so in a reasonable time frame.

Derivative Financial Instruments

Foreign Currency Exchange Rate Risk

When foreign currency exchange rate risk cannot be managed by operational strategies, we use derivative financial instruments, principally foreign currency forward purchase and sale contracts with terms of less than one year, to hedge our exposure to changes in foreign currency exchange rates. Our primary exposure to changes in foreign currency rates results from intercompany loans and accounts receivable and payable in nonfunctional currencies made between affiliates to minimize the need for borrowings from third parties. Additionally, we enter into foreign currency forward purchase and sale contracts to mitigate our exposure to changes in exchange rates on certain intercompany and third-party trade receivables and payables. We manage counter-party credit risk by entering into derivative financial instruments with major financial institutions that can be expected to fully perform under the terms of such agreements. We do not enter into derivative financial instruments for speculative purposes.

In managing our foreign currency exposures, we identify and then hedge exposures by creating offsetting intercompany exposures or through third-party derivative contracts. The fair value of our foreign currency forward contracts was a net asset position of less than $1 million at March 31, 2017 and is based on an internally developed model which incorporates observable inputs including quoted spot rates, forward exchange rates and discounted future expected cash flows utilizing market interest rates with similar quality and maturity characteristics. The following table summarizes by major currency the notional amounts for our foreign currency forward purchase and sale contracts as of March 31, 2017. All contracts in the following table mature in 2017.

Interest Rate Risk

Our financial instruments that are sensitive to market risk for changes in interest rates are primarily our debt securities. We use our revolving credit facility to finance our short-term and long-term capital requirements. We pay a current market rate of interest on these borrowings. Our long-term capital requirements have been financed with long-term debt with original maturity dates ranging from five to ten years. On March 31, 2017, we had $740 million in long-term debt obligations that have fixed interest rates. Of that amount, $500 million is fixed through July 2026, $225 million is fixed through December 2024, and the remainder is fixed from 2017 through 2025. We also have $684 million in long-term debt obligations that are subject to variable interest rates. For more detailed explanations on our debt structure and senior credit facility refer to “Liquidity and Capital Resources — Capitalization” earlier in this Management’s Discussion and Analysis.

We estimate that the fair value of our long-term debt at March 31, 2017 was about 100 percent of its book value. A one percentage point increase or decrease in interest rates related to our variable interest rate debt would increase or decrease the annual interest expense we recognize in the income statement and the cash we pay for interest expense by about $8 million.

Environmental Matters, Legal Proceedings and Product Warranties

Note 7 in our notes to condensed consolidated financial statements located in Part I Item 1 of this Form 10-Q is incorporated herein for reference.

Tenneco 401(K) Retirement Savings Plan

Effective January 1, 2012, the Tenneco Employee Stock Ownership Plan for Hourly Employees and the Tenneco Employee Stock Ownership Plan for Salaried Employees were merged into one plan called the Tenneco 401(k) Retirement Savings Plan (the “Retirement Savings Plan”). Under the plan, subject to limitations in the Internal Revenue Code, participants may elect to defer up to 75 percent of their salary through contributions to the plan, which are invested in selected mutual funds or used to buy our common stock. We match 100 percent of an employee's contributions up to three percent of the employee's salary and 50 percent of an employee's contributions that are between three percent and five percent of the employee's salary. In connection with freezing the defined benefit pension plans for nearly all U.S. based salaried and non-union hourly employees effective December 31, 2006, and the related replacement of those defined benefit plans with defined contribution plans, we are making additional contributions to the Retirement Savings Plan. We recorded expense for these contributions of approximately $6 million and $7 million for the three month periods ended March 31, 2017 and 2016, respectively. Matching contributions vest immediately. Defined benefit replacement contributions fully vest on the employee’s third anniversary of employment.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

For information regarding our exposure to interest rate risk and foreign currency exchange rate risk, see the caption entitled “Derivative Financial Instruments” in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations,” which is incorporated herein by reference.

ITEM 4.CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

An evaluation was carried out under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934) as of the end of the quarter covered by this report. Based on their evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are effective to ensure that information required to be disclosed by our Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and such information is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosures.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting during the quarter ended March 31, 2017, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

48

PART II

ITEM 1A.RISK FACTORS

We are exposed to certain risks and uncertainties that could have a material adverse impact on our business, financial condition and operating results. There have been no other material changes to the Risk Factors described in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

ITEM 2.UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

(a) None.

(b) Not applicable.

(c) Purchase of equity securities by the issuer and affiliated purchasers. The following table provides information relating to our purchase of shares of our common stock in the first quarter of 2017. These purchases reflect shares withheld upon vesting of restricted stock for tax withholding obligations as well as shares repurchased through our share repurchase program. We generally intend to continue to satisfy tax withholding obligations in connection with the vesting of outstanding restricted stock through the withholding of shares.

In January 2015, our Board of Directors approved a share repurchase program, authorizing our company to repurchase up to $350 million of our outstanding common stock over a three year period. In October 2015, our Board of Directors expanded this share repurchase program, authorizing the repurchase of an additional $200 million of the Company's outstanding common stock. In February 2017, our Board of Directors authorized the repurchase of up to $400 million of the Company's outstanding common stock over the next three years. This includes $112 million that remained authorized under earlier repurchase programs. The Company anticipates acquiring the shares through open market or privately negotiated transactions, which will be funded through cash from operations. The repurchase program does not obligate the Company to repurchase shares within any specific time or situations, and opportunities in higher priority areas could affect the cadence of this program. We repurchased 240,000 shares for $16 million through this program in the three months ended March 31, 2017. Since we announced the share repurchase program in January 2015, we have repurchased 8.7 million shares for $454 million through March 31, 2017.

Period	Total Number of Shares Purchased (1)	Average Price Paid		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs	Maximum Value of Shares That May Yet be Purchased Under These Plans or Programs (Millions)
January 2017	75,947	$	66.10	—	$	400
February 2017	48,653	$	68.34	—	400
March 2017	256,446	$	64.99	240,000	384
Total	381,046	$	65.64	240,000	$	384

(1) Includes shares withheld upon vesting of restricted stock in the amount of 75,947 in January 2017, 48,653 in February 2017 and 16,446 in March 2017.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Consolidation and Presentation

Consolidation and Presentation

As you read the accompanying financial statements you should also read our Annual Report on Form 10-K for the year ended December 31, 2016.

In our opinion, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly Tenneco Inc.’s results of operations, comprehensive income, financial position, cash flows, and changes in shareholders’ equity for the periods indicated. We have prepared the unaudited condensed consolidated financial statements pursuant to the rules and regulations of the U.S. Securities and Exchange Commission for interim financial information. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (U.S. GAAP) for annual financial statements.

Our condensed consolidated financial statements include all majority-owned subsidiaries. We carry investments in 20 percent to 50 percent owned companies in which the Company does not have a controlling interest, as equity method investments, at cost plus equity in undistributed earnings since the date of acquisition and cumulative translation adjustments. We have eliminated all intercompany transactions.

Prepayments and Other

Prepayments and other included $126 million and $97 million at March 31, 2017 and December 31, 2016, respectively, for in-process tools and dies that we are building for our original equipment customers.

Accounts Payable

Accounts payable included $88 million and $99 million at March 31, 2017 and December 31, 2016, respectively, for accrued compensation and $30 million and $27 million at March 31, 2017 and December 31, 2016, respectively, for bank overdrafts at our European subsidiaries.

Fair Value Disclosures [Abstract]

Financial Instruments

Financial Instruments

The net carrying and estimated fair values of our financial instruments by class at March 31, 2017 and December 31, 2016 were as follows:

	March 31, 2017				December 31, 2016
	Net Carrying Amount		Fair Value		Net Carrying Amount		Fair Value
	(Millions)
Long-term debt (including current maturities)	$	1,409	$	1,418	$	1,297	$	1,311
Instruments with off-balance sheet risk:
Foreign exchange forward contracts:
Asset derivative contracts	—		—		—		—

Asset and Liability Instruments — The fair value of cash and cash equivalents, short and long-term receivables, accounts payable, and short-term debt was considered to be the same as or was not determined to be materially different from the carrying amount.

Long-term Debt — The fair value of our public fixed rate senior notes is based on quoted market prices (level 1). The fair value of our private borrowings under our senior credit facility and other long-term debt instruments is based on the market value of debt with similar maturities, interest rates and risk characteristics (level 2). The fair value of our level 1 debt, as classified in the fair value hierarchy, was $721 million and $725 million at March 31, 2017 and December 31, 2016, respectively. We have classified $682 million and $571 million as level 2 in the fair value hierarchy at March 31, 2017 and December 31, 2016, respectively, since we utilize valuation inputs that are observable both directly and indirectly. We classified the remaining $15 million, consisting of foreign subsidiary debt, as level 3 in the fair value hierarchy at both March 31, 2017 and December 31, 2016.

The fair value hierarchy definition prioritizes the inputs used in measuring fair value into the following levels:

Level 1	—	Quoted prices in active markets for identical assets or liabilities.
Level 2	—	Inputs, other than quoted prices in active markets, that are observable either directly or indirectly.
Level 3	—	Unobservable inputs based on our own assumptions.

Foreign Exchange Forward Contracts — We use derivative financial instruments, principally foreign currency forward purchase and sales contracts with terms of less than one year, to hedge our exposure to changes in foreign currency exchange rates. Our primary exposure to changes in foreign currency rates results from intercompany loans made between affiliates to minimize the need for borrowings from third parties. Additionally, we enter into foreign currency forward purchase and sale contracts to mitigate our exposure to changes in exchange rates on certain intercompany and third-party trade receivables and payables. We manage counter-party credit risk by entering into derivative financial instruments with major financial institutions that can be expected to fully perform under the terms of such agreements. We do not enter into derivative financial instruments for speculative purposes. The fair value of our foreign currency forward contracts is based on an internally developed model which incorporates observable inputs including quoted spot rates, forward exchange rates and discounted future expected cash flows utilizing market interest rates with similar quality and maturity characteristics. We record the change in fair value of these foreign exchange forward contracts as part of currency gains (losses) within cost of sales in the consolidated statements of income. The fair value of foreign exchange forward contracts are recorded in prepayments and other current assets or other current liabilities in the consolidated balance sheet. The fair value of our foreign currency forward contracts was a net asset position of less than $1 million at March 31, 2017 and a net liability position of less than $1 million at December 31, 2016, respectively.

The following table summarizes by major currency the notional amounts for foreign currency forward purchase and sale contracts as of March 31, 2017 (all of which mature in 2017):

		Notional Amount in Foreign Currency
		(Millions)
British pounds	—Purchase	19
	—Sell	(9	)
Canadian dollars	—Purchase	2
	—Sell	(4	)
European euro	—Purchase	10

South African rand	—Sell	(7	)
U.S. dollars	—Purchase	21
	—Sell	(35	)

Guarantees —We have from time to time issued guarantees for the performance of obligations by some of our subsidiaries, and some of our subsidiaries have guaranteed our debt. All of our existing and future material domestic subsidiaries fully and unconditionally guarantee our senior credit facility and our senior notes on a joint and several basis. The arrangement for the senior credit facility is also secured by first-priority liens on substantially all our domestic assets and pledges of up to 66 percent of the stock of certain first-tier foreign subsidiaries. No assets or capital stock secure our senior notes. For additional information, refer to Note 13 of the condensed consolidated financial statements of Tenneco Inc., where we present the Supplemental Guarantor Condensed Consolidating Financial Statements.

We have two performance guarantee agreements in the U.K. between Tenneco Management (Europe) Limited (“TMEL”) and the two Walker Group Retirement Plans, the Walker Group Employee Benefit Plan and the Walker Group Executive Retirement Benefit Plan (the “Walker Plans”), whereby TMEL will guarantee the payment of all current and future pension contributions in the event of a payment default by the sponsoring or participating employers of the Walker Plans. The Walker Plans are comprised of employees from Tenneco Walker (U.K.) Limited and Futaba (U.K.) Limited, formerly our Futaba-Tenneco (U.K.) joint venture. Employer contributions are funded by Tenneco Walker (U.K.) Limited, as the sponsoring employer, and were also funded by Futaba (U.K.) Limited prior to its ceasing, on April 28, 2017, to be an entity in which Tenneco has an equity interest. The performance guarantee agreements are expected to remain in effect until all pension obligations for the Walker Plans’ sponsoring and participating employers have been satisfied. We did not record an additional liability for this performance guarantee since Tenneco Walker (U.K.) Limited, as the sponsoring employer of the Walker Plans, already recognizes 100 percent of the pension obligation calculated based on U.S. GAAP, for all of the Walker Plans’ participating employers on its balance sheet, which was $18 million and $19 million at March 31, 2017 and December 31, 2016, respectively. At March 31, 2017, all pension contributions under the Walker Plans were current for all of the Walker Plans’ sponsoring and participating employers.

In June 2011, we entered into an indemnity agreement between TMEL and Futaba Industrial Co. Ltd. which required Futaba to indemnify TMEL for any cost, loss or liability which TMEL may have incurred under the performance guarantee agreements relating to the Futaba-Tenneco U.K. joint venture. The maximum amount reimbursable by Futaba to TMEL under this indemnity agreement was equal to the amount incurred by TMEL under the performance guarantee agreements multiplied by Futaba’s shareholder ownership percentage of the Futaba-Tenneco U.K. joint venture. At March 31, 2017, the maximum amount reimbursable by Futaba to TMEL was approximately $8 million. Subsequently, on April 28, 2017, Walker Limited sold its equity interest in the Futaba-Tenneco U.K. joint venture entity to Futaba Industrial Co., Ltd. In connection with the closing of that transaction, this indemnity agreement was terminated and accordingly Futaba no longer has any reimbursement obligations thereunder.

We have issued guarantees through letters of credit in connection with some obligations of our affiliates. As of March 31, 2017, we have guaranteed $31 million in letters of credit to support some of our subsidiaries’ insurance arrangements, foreign employee benefit programs, environmental remediation activities and cash management and capital requirements.

Financial Instruments — One of our European subsidiaries receives payment from one of its customers whereby the accounts receivable are satisfied through the delivery of negotiable financial instruments. We may collect these financial instruments before their maturity date by either selling them at a discount or using them to satisfy accounts receivable that have previously been sold to a European bank. Any of these financial instruments which are not sold are classified as other current assets. Such financial instruments held by our European subsidiary totaled zero and less than $1 million at March 31, 2017 and December 31, 2016, respectively.

In certain instances, several of our Chinese subsidiaries receive payment from customers through the receipt of financial instruments on the date the customer payments are due. Several of our Chinese subsidiaries also satisfy vendor payments through the delivery of financial instruments on the date the payments are due. Financial instruments issued to satisfy vendor payables and not redeemed totaled $12 million at both March 31, 2017 and December 31, 2016 and were classified as notes payable. Financial instruments received from original equipment (OE) customers and not redeemed totaled $9 million and $5 million at March 31, 2017 and December 31, 2016, respectively. We classify financial instruments received from our customers as other current assets if issued by a financial institution of our customers or as customer notes and accounts, net if issued by our customer. We classified $9 million and $5 million in other current assets at March 31, 2017 and December 31, 2016, respectively.

The financial instruments received by one of our European subsidiaries and some of our Chinese subsidiaries are drafts drawn that are payable at a future date and, in some cases, are negotiable and/or are guaranteed by the banks of the customers. The use of these instruments for payment follows local commercial practice. Because certain of such financial instruments are guaranteed by our customers’ banks, we believe they represent a lower financial risk than the outstanding accounts receivable that they satisfy which are not guaranteed by a bank.

Supply Chain Financing — Certain of our suppliers participate in supply chain financing programs under which they securitize their accounts receivables from Tenneco. Financial institutions participate in the supply chain financing program on an uncommitted basis and can cease purchasing receivables or drafts from Tenneco's suppliers at any time. If the financial institutions did not continue to purchase receivables or drafts from Tenneco's suppliers under these programs, the participating vendors may have a need to renegotiate their payment terms with Tenneco which in turn would cause our borrowings under our revolving credit facility to increase.

Restricted Cash — Some of our Chinese subsidiaries that issue their own financial instruments to pay vendors are required to maintain a cash balance if they exceed credit limits with the financial institution that guarantees the financial instruments. A restricted cash balance was required at those Chinese subsidiaries for $2 million at both March 31, 2017 and December 31, 2016.

One of our subsidiaries in Brazil is required by law to maintain a cash deposit with the financial institution to guarantee the maximum estimated loss related to a tax audit until a settlement is reached. The cash deposit required was $1 million which has been classified as restricted cash on the Tenneco Inc. consolidated balance sheet at March 31, 2017.

Long-Term Debt and Financing Arrangements

Long-Term Debt and Financing Arrangements

Our financing arrangements are primarily provided by a committed senior secured financing arrangement with a syndicate of banks and other financial institutions. The arrangement is secured by substantially all our domestic assets and pledges of up to 66 percent of the stock of certain first-tier foreign subsidiaries, as well as guarantees by our material domestic subsidiaries.

As of March 31, 2017, the senior credit facility provides us with a total revolving credit facility size of $1,200 million and had a $264 million balance outstanding under the Tranche A Term Facility, both of which will mature on December 8, 2019. Net carrying amount for the balance outstanding under the Tranche A Term Facility including a $1 million debt issuance cost was $263 million as of March 31, 2017. Funds may be borrowed, repaid and re-borrowed under the revolving credit facility without premium or penalty (subject to any customary LIBOR breakage fees). The revolving credit facility is reflected as debt on our balance sheet only if we borrow money under this facility or if we use the facility to make payments for letters of credit. Outstanding letters of credit reduce our availability to borrow revolving loans under the facility. We are required to make quarterly principal payments under the Tranche A Term Facility of $5.625 million through December 31, 2017, $7.5 million beginning March 31, 2018 through September 30, 2019 and a final payment of $195 million is due on December 8, 2019. We have excluded the required payments, within the next twelve months, under the Tranche A Term Facility totaling $24 million from current liabilities as of March 31, 2017, because we have the intent and ability to refinance the obligations on a long-term basis by using our revolving credit facility.

The financial ratios required under the senior credit facility, and the actual ratios we achieved for the first quarter of 2017, are as follows:

	Quarter Ended
	March 31, 2017
	Required	Actual
Leverage Ratio (maximum)	3.50	1.58
Interest Coverage Ratio (minimum)	2.75	15.73

The senior credit facility includes a maximum leverage ratio covenant of 3.50 and a minimum interest coverage ratio of 2.75, in each case through December 8, 2019.

At March 31, 2017, of the $1,200 million available under the revolving credit facility, we had unused borrowing capacity of $783 million with $417 million in outstanding borrowings and no outstanding letters of credit. As of March 31, 2017, our outstanding debt also included (i) $264 million of a term loan which consisted of a $263 million net carrying amount including a $1 million debt issuance cost related to our Tranche A Term Facility which is subject to quarterly principal payments as described above through December 8, 2019, (ii) $225 million of notes which consisted of a $221 million net carrying amount including a $4 million debt issuance cost related to our 5³/₈ percent senior notes due December 15, 2024, (iii) $500 million of notes which consisted of a $492 million net carrying amount including a $8 million debt issuance cost related to our 5 percent senior notes due July 15, 2026 (which were issued on June 13, 2016), and (iv) $126 million of other debt.

Income Taxes

Income Taxes

For interim tax reporting we estimate our annual effective tax rate and apply it to our year to date ordinary income. Jurisdictions where no tax benefit can be recognized due to a valuation allowance are excluded from the estimated annual effective tax rate. The impact of including these jurisdictions on the quarterly effective rate calculation could result in a higher or lower effective tax rate during a particular quarter due to the mix and timing of actual earnings versus annual projections. The tax effects of certain unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are excluded from the estimated annual effective tax rate calculation and recognized in the interim period in which they occur.

We reported income tax expense of $34 million in each of the three month periods ended March 31, 2017 and 2016. The tax expense recorded in the first quarter of 2017 included a net tax benefit of $1 million primarily relating to the first quarter 2017 adoption of Accounting Standard Update 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The tax expense recorded in the first quarter of 2016 included a net tax benefit of $3 million primarily relating to tax adjustments to uncertain tax positions and prior year income tax estimates.

We believe it is reasonably possible that up to $17 million in unrecognized tax benefits related to the expiration of foreign statute of limitations and the conclusion of income tax examinations may be recognized within the next twelve months.

Accounts Receivable Securitization

Accounts Receivable Additional Disclosures [Abstract]

Accounts Receivable Securitization

Accounts Receivable Securitization

We securitize some of our accounts receivable on a limited recourse basis in the U.S. and Europe. As servicer under these accounts receivable securitization programs, we are responsible for performing all accounts receivable administration functions for these securitized financial assets including collections and processing of customer invoice adjustments. In the U.S., we have an accounts receivable securitization program with three commercial banks comprised of a first priority facility and a second priority facility. We securitize original equipment and aftermarket receivables on a daily basis under the bank program. In April 2017, the U.S. program was amended and extended to April 30, 2019. The first priority facility now provides financing of up to $155 million and the second priority facility, which is subordinated to the first priority facility, now provides up to an additional $25 million of financing. Both facilities monetize accounts receivable generated in the U.S. and Canada that meet certain eligibility requirements, and the second priority facility also monetizes certain accounts receivable generated in the U.S. and Canada that would otherwise be ineligible under the first priority securitization facility. The amount of outstanding third-party investments in our securitized accounts receivable under the U.S. program was $50 million and $30 million at March 31, 2017 and December 31, 2016, respectively.

Each facility contains customary covenants for financings of this type, including restrictions related to liens, payments, mergers or consolidations and amendments to the agreements underlying the receivables pool. Further, each facility may be terminated upon the occurrence of customary events (with customary grace periods, if applicable), including breaches of covenants, failure to maintain certain financial ratios, inaccuracies of representations and warranties, bankruptcy and insolvency events, certain changes in the rate of default or delinquency of the receivables, a change of control and the entry or other enforcement of material judgments. In addition, each facility contains cross-default provisions, where the facility could be terminated in the event of non-payment of other material indebtedness when due and any other event which permits the acceleration of the maturity of material indebtedness.

We also securitize receivables in our European operations with regional banks in Europe. The arrangements to securitize receivables in Europe are provided under seven separate facilities provided by various financial institutions in each of the foreign jurisdictions. The commitments for these arrangements are generally for one year, but some may be canceled with notice 90 days prior to renewal. In some instances, the arrangement provides for cancellation by the applicable financial institution at any time upon notification. The amount of outstanding third-party investments in our securitized accounts receivable in Europe was $209 million and $160 million at March 31, 2017 and December 31, 2016, respectively.

If we were not able to securitize receivables under either the U.S. or European securitization programs, our borrowings under our revolving credit agreement might increase. These accounts receivable securitization programs provide us with access to cash at costs that are generally favorable to alternative sources of financing, and allow us to reduce borrowings under our revolving credit agreement.

In our U.S. accounts receivable securitization program, we transfer a partial interest in a pool of receivables and the interest that we retain is subordinate to the transferred interest. Accordingly, we account for our U.S. 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 ASC Topic 860, “Transfers and Servicing,” to report the transfer of financial assets in their entirety as a sale. The fair value of assets received as proceeds in exchange for the transfer of accounts receivable under our European securitization programs approximates the fair value of such receivables. We recognized $1 million interest expense in each of the three month periods ended March 31, 2017 and 2016 relating to our U.S. securitization program. In addition, we recognized a loss of $1 million in each of the three month periods ended March 31, 2017 and 2016 on the sale of trade accounts receivable in our European accounts receivable securitization programs, representing the discount from book values at which these receivables were sold to our banks. The discount rate varies based on funding costs incurred by our banks, which averaged approximately two percent during the first three months of both 2017 and 2016.

Restructuring and Related Activities [Abstract]

Restructuring and Other Charges

Restructuring and Other Charges

Over the past several years, we have adopted plans to restructure portions of our operations. These plans were approved by our Board of Directors and were designed to reduce operational and administrative overhead costs throughout the business. For the full year 2016, we incurred $36 million in restructuring and related costs including asset write-downs of $6 million, primarily related to manufacturing footprint improvements in North America Ride Performance, headcount reduction and cost improvement initiatives in Europe and China Clean Air, South America and Australia, of which $17 million was recorded in cost of sales, $12 million in SG&A, $1 million in engineering expense, $2 million in other expense and $4 million in depreciation and amortization expense. In the first quarter of 2017, we incurred $15 million in restructuring and related costs, including asset write-downs of $1 million, primarily related to closing a Clean Air Belgian JIT plant in response to the end of production on a customer platform and cost improvement initiatives in Europe, of which $11 million was recorded in cost of sales, $3 million in SG&A and $1 million in depreciation and amortization expense. In the first quarter of 2016, we incurred $14 million in restructuring and related costs including asset write-downs of $5 million, primarily related to European cost reduction efforts and headcount reductions in South America, of which $3 million was recorded in cost of sales, $6 million in SG&A, $2 million in other expense and $3 million in depreciation and amortization expense.

Amounts related to activities that are part of our restructuring reserves are as follows:

	December 31, 2016 Restructuring Reserve		2017 Expenses	2017 Cash Payments		Impact of Exchange Rates	March 31, 2017 Restructuring Reserve
	(Millions)
Employee Severance, Termination Benefits and Other Related Costs		$15	13	(6	)	—		$22

On January 31, 2013, we announced our intent to reduce structural costs in Europe by approximately $60 million annually. During the first quarter of 2016, we reached an annualized run rate on this cost reduction initiative of $49 million. With the disposition of the Gijon, Spain plant, which was completed at the end of the first quarter of 2016, the annualized rate essentially reached our target of $55 million at the current exchange rates at that time. In the first quarter of 2017, we incurred $15 million in restructuring and related costs, of which $2 million was related to this initiative. While we are nearing the completion of this initiative, we expect to incur additional restructuring and related costs in 2017 due to certain ongoing matters. For example, we closed the Gijon plant in 2013, but subsequently re-opened it in July 2014 with about half of its prior workforce after the employees' works council successfully filed suit challenging the closure decision. Pursuant to an agreement we entered into with employee representatives, we engaged in a sales process for the facility. In March of 2016, we signed an agreement to transfer ownership of the aftermarket shock absorber manufacturing facility in Gijon to German private equity fund Quantum Capital Partners A.G. (QCP). The transfer to QCP was effective March 31, 2016 and under a three year manufacturing agreement, QCP will also continue as a supplier to Tenneco.

Under the terms of our amended and restated senior credit agreement that took effect on December 8, 2014, we are allowed to exclude up to $150 million in the aggregate of all costs, expenses, fees, fines, penalties, judgments, legal settlements and other amounts associated with any restructuring, litigation, claim, proceeding or investigation related to or undertaken by us or any of our subsidiaries, together with any related provision for taxes, incurred after December 8, 2014 in the calculation of the financial covenant ratios required under our senior credit facility. As of March 31, 2017, we had excluded $96 million of allowable charges relating to restructuring initiatives against the $150 million available under the terms of the senior credit facility.

Environmental Matters, Litigation and Product Warranties [Abstract]

Environmental Matters, Litigation and Product Warranties

Environmental Matters, Legal Proceedings and Product Warranties

We are involved in environmental remediation matters, legal proceedings, claims, investigations and warranty obligations. These matters are typically incidental to the conduct of our business and create the potential for contingent losses. We accrue for potential contingent losses when our review of available facts indicates that it is probable a loss has been incurred and the amount of the loss is reasonably estimable. Each quarter we assess our loss contingencies based upon currently available facts, existing technology, presently enacted laws and regulations and taking into consideration the likely effects of inflation and other societal and economic factors and record adjustments to these reserves as required. As an example, we consider all available evidence, including prior experience in remediation of contaminated sites, other companies’ cleanup experiences and data released by the United States Environmental Protection Agency or other organizations when we evaluate our environmental remediation contingencies. All of our loss contingency estimates are subject to revision in future periods based on actual costs or new information. With respect to our environmental liabilities, where future cash flows are fixed or reliably determinable, we have discounted those liabilities. We evaluate recoveries separately from the liability and, when they are assured, recoveries are recorded and reported separately from the associated liability in our consolidated financial statements.

Environmental Matters

We are subject to a variety of environmental and pollution control laws and regulations in all jurisdictions in which we operate. We expense or capitalize, as appropriate, expenditures for ongoing compliance with environmental regulations that relate to current operations. We expense costs related to an existing condition caused by past operations that do not contribute to current or future revenue generation. As of March 31, 2017, we have the obligation to remediate or contribute towards the remediation of certain sites, including one Federal Superfund site. At March 31, 2017, our aggregated estimated share of environmental remediation costs for all these sites on a discounted basis was approximately $15 million, of which $2 million is recorded in other current liabilities and $13 million is recorded in deferred credits and other liabilities in our consolidated balance sheet. For those locations where the liability was discounted, the weighted average discount rate used was 2.5 percent. The undiscounted value of the estimated remediation costs was $18 million. Our expected payments of environmental remediation costs are estimated to be approximately $1 million in each year beginning 2017 through 2021 and $13 million in aggregate thereafter.

Based on information known to us, we have established reserves that we believe are adequate for these costs. Although we believe these estimates of remediation costs are reasonable and are based on the latest available information, the costs are estimates and are subject to revision as more information becomes available about the extent of remediation required. At some sites, we expect that other parties will contribute to the remediation costs. In addition, certain environmental statutes provide that our liability could be joint and several, meaning that we could be required to pay in excess of our share of remediation costs. Our understanding of the financial strength of other potentially responsible parties at these sites has been considered, where appropriate, in our determination of our estimated liability. We do not believe that any potential costs associated with our current status as a potentially responsible party in the Federal Superfund site, or as a liable party at the other locations referenced herein, will be material to our consolidated financial position, results of operations, or liquidity.

Antitrust Investigations and Litigation

On March 25, 2014, representatives of the European Commission were at Tenneco GmbH's Edenkoben, Germany administrative facility to gather information in connection with an ongoing global antitrust investigation concerning multiple automotive suppliers. On March 25, 2014, we also received a related subpoena from the U.S. Department of Justice ("DOJ").

On November 5, 2014, the DOJ granted us conditional leniency pursuant to an agreement we entered into under the Antitrust Division's Corporate Leniency Policy. This agreement provides us with important benefits in exchange for our self-reporting of matters to the DOJ and our continuing full cooperation with the DOJ's resulting investigation. For example, the DOJ will not bring any criminal antitrust prosecution against us, nor seek any criminal fines or penalties, in connection with the matters we reported to the DOJ. Additionally, there are limits on our liability related to any follow-on civil antitrust litigation in the U.S. The limits include single rather than treble damages, as well as relief from joint and several antitrust liability with other relevant civil antitrust action defendants. These limits are subject to our satisfying the DOJ and any court presiding over such follow-on civil litigation.

On April 27, 2017, Tenneco received notification from the European Commission (EC) that it has administratively closed its global antitrust inquiry regarding the production, assembly, and supply of complete exhaust systems. No charges against Tenneco or any other competitor were initiated at any time and the EC inquiry is now closed.

Certain other competition agencies are also investigating possible violations of antitrust laws relating to products supplied by our company. We have cooperated and continue to cooperate fully with all of these antitrust investigations, and take other actions to minimize our potential exposure.

Tenneco and certain of its competitors are also currently defendants in civil putative class action litigation in the United States. More related lawsuits may be filed, including in other jurisdictions. Plaintiffs in these cases generally allege that defendants have engaged in anticompetitive conduct, in violation of federal and state laws, relating to the sale of automotive exhaust systems or components thereof. Plaintiffs seek to recover, on behalf of themselves and various purported classes of purchasers, injunctive relief, damages and attorneys’ fees. However, as explained above, because we received conditional leniency from the DOJ, our civil liability in these follow-on actions is limited to single damages and we will not be jointly and severally liable with the other defendants, provided that we have satisfied our obligations under the DOJ leniency agreement and approval is granted by the presiding court.

Antitrust law investigations, civil litigation, and related matters often continue for several years and can result in significant penalties and liability. We intend to vigorously defend the Company and/or take other actions to minimize our potential exposure. In light of the many uncertainties and variables involved, we cannot estimate the ultimate impact that these matters may have on our company. Further, there can be no assurance that the ultimate resolution of these matters will not have a material adverse effect on our consolidated financial position, results of operations or liquidity.

Other Legal Proceedings, Claims and Investigations

We are also from time to time involved in other legal proceedings, claims or investigations. Some of these matters involve allegations of damages against us relating to environmental liabilities (including toxic tort, property damage and remediation), intellectual property matters (including patent, trademark and copyright infringement, and licensing disputes), personal injury claims (including injuries due to product failure, design or warning issues, and other product liability related matters), taxes, unclaimed property, employment matters, and commercial or contractual disputes, sometimes related to acquisitions or divestitures. Additionally, some of these matters involve allegations relating to legal compliance. While we vigorously defend ourselves against all of these legal proceedings, claims and investigations and take other actions to minimize our potential exposure, in future periods, we could be subject to cash costs or charges to earnings if any of these matters are resolved on unfavorable terms. Although the ultimate outcome of any legal matter cannot be predicted with certainty, based on current information, including our assessment of the merits of the particular claim, except as described above under "Antitrust Investigations," we do not expect the legal proceedings, claims or investigations currently pending against us will have any material adverse impact on our consolidated financial position, results of operations or liquidity.

In addition, for many years we have been and continue to be subject to lawsuits initiated by claimants alleging health problems as a result of exposure to asbestos. Our current docket of active and inactive cases is less than 500 cases nationwide. A small number of claims have been asserted against one of our subsidiaries by railroad workers alleging exposure to asbestos products in railroad cars. The substantial majority of the remaining claims are related to alleged exposure to asbestos in our automotive products although a significant number of those claims appear also to involve occupational exposures sustained in industries other than automotive. We believe, based on scientific and other evidence, it is unlikely that claimants were exposed to asbestos by our former products and that, in any event, they would not be at increased risk of asbestos-related disease based on their work with these products. Further, many of these cases involve numerous defendants, with the number in some cases exceeding 100 defendants from a variety of industries. Additionally, in many cases the plaintiffs either do not specify any, or specify the jurisdictional minimum, dollar amount for damages. As major asbestos manufacturers and/or users continue to go out of business or file for bankruptcy, we may experience an increased number of these claims. We vigorously defend ourselves against these claims as part of our ordinary course of business. In future periods, we could be subject to cash costs or charges to earnings if any of these matters are resolved unfavorably to us. To date, with respect to claims that have proceeded sufficiently through the judicial process, we have regularly achieved favorable resolutions. Accordingly, we presently believe that these asbestos-related claims will not have a material adverse impact on our future consolidated financial position, results of operations or liquidity.

Warranty Matters

We provide warranties on some of our products. The warranty terms vary but range from one year up to limited lifetime warranties on some of our premium aftermarket products. Provisions for estimated expenses related to product warranty are made at the time products are sold or when specific warranty issues are identified with our products. These estimates are established using historical information about the nature, frequency, and average cost of warranty claims. We actively study trends of our warranty claims and take action to improve product quality and minimize warranty claims. We believe that the warranty reserve is appropriate; however, actual claims incurred could differ from the original estimates, requiring adjustments to the reserve. The reserve is included in both current and long-term liabilities on the balance sheet.

Below is a table that shows the activity in the warranty accrual accounts:

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Common Stock

Common Stock

Equity Plans — We have granted a variety of awards, including common stock, restricted stock, restricted stock units, performance units, stock appreciation rights (“SARs”), and stock options to our directors, officers, and employees.

Accounting Methods — We recorded compensation expense (net of taxes) of less than $1 million in each of the three month periods ended March 31, 2017 and 2016 related to nonqualified stock options as part of our selling, general and administrative expense. This had no impact on basic or diluted earnings per share for each of the three month periods ended March 31, 2017 and 2016.

For employees eligible to retire at the grant date, we immediately expense stock options and restricted stock. If employees become eligible to retire during the vesting period, we accelerate the recognition of any remaining expense associated with their stock options and restricted stock.

As of March 31, 2017, there was no unrecognized compensation cost related to our stock option awards.

Compensation expense for restricted stock, restricted stock units, long-term performance units and SARs (net of taxes) was $6 million and $7 million for the three month periods ended March 31, 2017 and 2016, respectively, and was recorded in selling, general, and administrative expense in our condensed consolidated statements of income.

Cash received from stock option exercises for the three month periods ended March 31, 2017 and 2016 was $6 million and less than $1 million, respectively.

Stock options exercised in the first three months of 2017 and 2016 generated a tax benefit of $2 million and a tax shortfall of less than $1 million, respectively.

Stock Options — The following table reflects the status and activity for all options to purchase common stock for the period indicated:

	Three Months Ended March 31, 2017
	Shares Under Option		Weighted Avg. Exercise Prices		Weighted Avg. Remaining Life in Years	Aggregate Intrinsic Value
						(Millions)
Outstanding Stock Options
Outstanding, January 1, 2017	606,525		$	38.54	2.6	$	12
Canceled	(2,214	)	56.23			—
Forfeited	(1,107	)	56.23			—
Exercised	(164,863	)	33.70			5
Outstanding, March 31, 2017	438,341		$	40.22	2.6	$	11

There have been no stock options granted since 2015. The total fair value of shares vested from options that were granted prior to 2015 was $2 million for each of the periods ended March 31, 2017 and 2016.

Restricted Stock — The following table reflects the status for all nonvested restricted shares for the period indicated:

	Three Months Ended March 31, 2017
	Shares		Weighted Avg. Grant Date Fair Value
Nonvested Restricted Shares
Nonvested balance at January 1, 2017	591,416		$	44.63
Granted	182,543		68.04
Vested	(261,003	)	50.95
Forfeited	(65,354	)	53.12
Nonvested balance at March 31, 2017	447,602		$	49.25

The fair value of restricted stock grants is usually equal to the average of the high and low trading price of our stock on the date of grant. As of March 31, 2017, approximately $24 million of total unrecognized compensation costs related to restricted stock awards is expected to be recognized over a weighted-average period of approximately 1.7 years. The total fair value of restricted shares vested was $13 million and $7 million at March 31, 2017 and 2016, respectively.

Share Repurchase Program — In January 2015, our Board of Directors approved a share repurchase program, authorizing our company to repurchase up to $350 million of our outstanding common stock over a three year period. In October 2015, our Board of Directors expanded this share repurchase program, authorizing the repurchase of an additional $200 million of the Company's outstanding common stock. In February 2017, our Board of Directors authorized the repurchase of up to $400 million of the Company's outstanding common stock over the next three years. This includes $112 million that remained authorized under earlier repurchase programs. The Company anticipates acquiring the shares through open market or privately negotiated transactions, which will be funded through cash from operations. The repurchase program does not obligate the Company to repurchase shares within any specific time or situations, and opportunities in higher priority areas could affect the cadence of this program. We repurchased 240,000 shares for $16 million through this program in the three months ended March 31, 2017. Since we announced the share repurchase program in January 2015, we have repurchased 8.7 million shares for $454 million through March 31, 2017.

Treasury stock shares including repurchased shares were 11,895,938 and 11,655,938 shares at March 31, 2017 and December 31, 2016, respectively.

Dividends — On February 1, 2017, Tenneco announced the reinstatement of a quarterly dividend program. We expect to pay a quarterly dividend of $0.25 per share on our common stock, representing a planned annual dividend of $1.00 per share. In March 2017, we paid an initial quarterly dividend of $0.25 per share, or $13 million. While we currently expect that comparable quarterly cash dividends will continue to be paid in the future, our dividend program and the payment of future cash dividends under the program are subject to continued capital availability, the judgment of our Board of Directors and our continued compliance with the provisions pertaining to the payment of dividends under our debt agreements.

Long-Term Performance Units, Restricted Stock Units and SARs — Long-term performance units, restricted stock units and SARs are paid in cash and recognized as a liability based upon their fair value. As of March 31, 2017, $33 million of total unrecognized compensation costs is expected to be recognized over a weighted-average period of approximately 2.2 years.

For the three months ended March 31, 2017, we made pension contributions of $11 million and $3 million for our domestic and foreign pension plans, respectively. Based on current actuarial estimates, we believe we will be required to contribute approximately $18 million for the remainder of 2017, which includes estimated contributions for the pension buyout referenced below. Pension contributions beyond 2017 will be required, but those amounts will vary based upon many factors including, for example, the performance of our pension fund investments during 2017.

In February 2016, the Company launched a voluntary program to buy out active employees and retirees who had earned benefits in the U.S. pension plans. As of March 31, 2017, this program has been substantially completed with cash payments made from pension plan assets to those who elected to take the buyout. In connection with this program the Company contributed $10 million into the pension trust and recognized a non-cash charge of $6 million in the first quarter of 2017.

We made postretirement contributions of approximately $2 million during the first three months of 2017. Based on current actuarial estimates, we believe we will be required to contribute approximately $8 million for the remainder of 2017.

The assets of some of our pension plans are invested in trusts that permit commingling of the assets of more than one employee benefit plan for investment and administrative purposes. Each of the plans participating in the trust has interests in the net assets of the underlying investment pools of the trusts. The investments for all our pension plans are recorded at estimated fair value, in compliance with the accounting guidance on fair value measurement.

Amounts recognized for pension and postretirement benefits in other comprehensive income for the three months ended March 31, 2017 and 2016 include the following components:

New Accounting Pronouncements

New Accounting Pronouncements

In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The new guidance improves the presentation of net periodic pension cost and net period postretirement benefit cost. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

In November 2016, the FASB issued Accounting Standard Update 2016-18, Statement of Cash Flows - Restricted Cash (Topic 230) to eliminate diversity in practice in the presentation of restricted cash and restricted cash equivalents in the statement of cash flows. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

In October 2016, the FASB issued Accounting Standard Update 2016-16, Income Taxes - Intra Entity Transfers of Assets Other Than Inventory (Topic 740). The new standard changes the accounting for income taxes when a company transfers certain tangible and intangible assets, such as equipment or intellectual property, between entities in different tax jurisdictions. The new standard does not change the current accounting for the income taxes related to transfers of inventory. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

In March 2016, the FASB issued Accounting Standard Update 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, as part of its initiative to reduce complexity in accounting standards. The areas for simplification in this update involve several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. We adopted this standard for the first quarter of 2017. The impact of the adoption resulted in the following:

• We recorded a tax benefit of $2 million within income tax expense for the three months ended March 31, 2017 related to the excess tax benefit on share-based awards. Prior to adoption, this amount would have been recorded as an addition of additional paid-in capital.

• We no longer reclassify the excess tax benefit from operating activities to financing activities in the statement of cash flows. Cash payments made to the taxing authorities on employees' behalf for withheld shares are presented as financing activities. Tenneco elected to apply this change in presentation retrospectively and thus prior periods have been adjusted. The amounts were not material.

• We excluded the excess tax benefits from the assumed proceeds available to repurchase shares in the computation of our diluted earnings per share for the quarter ended March 31, 2017. The impact was not material.

In February 2016, the FASB issued Accounting Standard Update 2016-02, Leases (Topic 842). The amendments in this update create Topic 842, Leases, and supersede the leases requirements in Topic 840, Leases. Topic 842 specifies the accounting for leases. The objective of Topic 842 is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flow arising from a lease. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2018, and interim periods within those annual periods. We will adopt this amendment on January 1, 2019. We are currently evaluating the potential impact of this new guidance on our consolidated financial statements.

In May 2014, the FASB issued an amendment on revenue recognition. The amendment in this update creates Topic 606, Revenue from Contracts with Customers, and supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance throughout the Industry Topics of the Codification. In addition, the amendment supersedes the cost guidance in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts, and creates new Subtopic 340-40, Other Assets and Deferred Costs-Contracts with Customers. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The FASB approved a one-year deferral of the effective date from January 1, 2017 to January 1, 2018, while allowing for early adoption as of January 1, 2017 for public entities. We will adopt this amendment on January 1, 2018.

The guidance permits the use of either the retrospective or modified retrospective (cumulative effect) transition method and we have not yet selected which transition method we will apply.

We have established a cross-functional coordinated team to implement the guidance related to the recognition of revenue from contracts with customers. We are in the process of assessing our customer contracts, identifying contractual provisions that may result in a change in the timing or the amount of revenue recognized in comparison with current guidance, as well as assessing the enhanced disclosure requirements of the new guidance. Under current guidance we generally recognize revenue when products are shipped and risk of loss has transferred to the customer. Under the proposed requirements, the customized nature of some of our products combined with contractual provisions that provide us with an enforceable right to payment, may require us to recognize revenue prior to the product being shipped to the customer. We are also assessing pricing provisions contained in certain of our customer contracts. Pricing provisions contained in some of our customer contracts represent variable consideration or may provide the customer with a material right, potentially resulting in a different allocation of the transaction price than under current guidance. In addition, we are evaluating how the new guidance may impact our accounting for contractually guaranteed reimbursements related to customer tooling, engineering services and pre-production costs. Under the current applicable guidance, these customer reimbursements are recorded as cost recovery offsets; whereas under the new standard these guaranteed recoveries may represent consideration from contracts with customers and be recorded as revenues. We continue to evaluate the impact this guidance will have on our financial statements.

Segment Reporting [Abstract]

Segment Information

Segment Information

In connection with the reportable segment changes announced on February 7, 2017, our Clean Air and Ride Performance product lines in India, which have been reported as part of Europe, South America and India segments, will now be reported with their respective product lines in the Asia Pacific segments. Beginning with the first quarter of 2017, we are organized and manage our business along our two major product lines (clean air and ride performance) and three geographic areas (North America; Europe and South America; Asia Pacific), resulting in six operating segments (North America Clean Air, North America Ride Performance, Europe and South America Clean Air, Europe and South America Ride Performance, Asia Pacific Clean Air and Asia Pacific Ride Performance). Within each geographical area, each operating segment manufactures and distributes either clean air or ride performance products primarily for the original equipment and aftermarket industries. Each of the six operating segments constitutes a reportable segment. Costs related to other business activities, primarily corporate headquarter functions, are disclosed separately from the six operating segments as "Other." We evaluate segment performance based primarily on earnings before interest expense, income taxes, and noncontrolling interests. Products are transferred between segments and geographic areas on a basis intended to reflect as nearly as possible the “market value” of the products. Prior period segment information has been revised to reflect our new reporting segments.

The following table summarizes certain Tenneco Inc. segment information:

New Accounting Pronouncements (Policies)

Accounting Policies [Abstract]

New Accounting Pronouncements

New Accounting Pronouncements

In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The new guidance improves the presentation of net periodic pension cost and net period postretirement benefit cost. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

In November 2016, the FASB issued Accounting Standard Update 2016-18, Statement of Cash Flows - Restricted Cash (Topic 230) to eliminate diversity in practice in the presentation of restricted cash and restricted cash equivalents in the statement of cash flows. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

In October 2016, the FASB issued Accounting Standard Update 2016-16, Income Taxes - Intra Entity Transfers of Assets Other Than Inventory (Topic 740). The new standard changes the accounting for income taxes when a company transfers certain tangible and intangible assets, such as equipment or intellectual property, between entities in different tax jurisdictions. The new standard does not change the current accounting for the income taxes related to transfers of inventory. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

In March 2016, the FASB issued Accounting Standard Update 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, as part of its initiative to reduce complexity in accounting standards. The areas for simplification in this update involve several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. We adopted this standard for the first quarter of 2017. The impact of the adoption resulted in the following:

• We recorded a tax benefit of $2 million within income tax expense for the three months ended March 31, 2017 related to the excess tax benefit on share-based awards. Prior to adoption, this amount would have been recorded as an addition of additional paid-in capital.

• We no longer reclassify the excess tax benefit from operating activities to financing activities in the statement of cash flows. Cash payments made to the taxing authorities on employees' behalf for withheld shares are presented as financing activities. Tenneco elected to apply this change in presentation retrospectively and thus prior periods have been adjusted. The amounts were not material.

• We excluded the excess tax benefits from the assumed proceeds available to repurchase shares in the computation of our diluted earnings per share for the quarter ended March 31, 2017. The impact was not material.

In February 2016, the FASB issued Accounting Standard Update 2016-02, Leases (Topic 842). The amendments in this update create Topic 842, Leases, and supersede the leases requirements in Topic 840, Leases. Topic 842 specifies the accounting for leases. The objective of Topic 842 is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flow arising from a lease. For public business entities, the standard is effective for financial statements issued for annual periods beginning after December 15, 2018, and interim periods within those annual periods. We will adopt this amendment on January 1, 2019. We are currently evaluating the potential impact of this new guidance on our consolidated financial statements.

In May 2014, the FASB issued an amendment on revenue recognition. The amendment in this update creates Topic 606, Revenue from Contracts with Customers, and supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance throughout the Industry Topics of the Codification. In addition, the amendment supersedes the cost guidance in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts, and creates new Subtopic 340-40, Other Assets and Deferred Costs-Contracts with Customers. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The FASB approved a one-year deferral of the effective date from January 1, 2017 to January 1, 2018, while allowing for early adoption as of January 1, 2017 for public entities. We will adopt this amendment on January 1, 2018.

The guidance permits the use of either the retrospective or modified retrospective (cumulative effect) transition method and we have not yet selected which transition method we will apply.

We have established a cross-functional coordinated team to implement the guidance related to the recognition of revenue from contracts with customers. We are in the process of assessing our customer contracts, identifying contractual provisions that may result in a change in the timing or the amount of revenue recognized in comparison with current guidance, as well as assessing the enhanced disclosure requirements of the new guidance. Under current guidance we generally recognize revenue when products are shipped and risk of loss has transferred to the customer. Under the proposed requirements, the customized nature of some of our products combined with contractual provisions that provide us with an enforceable right to payment, may require us to recognize revenue prior to the product being shipped to the customer. We are also assessing pricing provisions contained in certain of our customer contracts. Pricing provisions contained in some of our customer contracts represent variable consideration or may provide the customer with a material right, potentially resulting in a different allocation of the transaction price than under current guidance. In addition, we are evaluating how the new guidance may impact our accounting for contractually guaranteed reimbursements related to customer tooling, engineering services and pre-production costs. Under the current applicable guidance, these customer reimbursements are recorded as cost recovery offsets; whereas under the new standard these guaranteed recoveries may represent consideration from contracts with customers and be recorded as revenues. We continue to evaluate the impact this guidance will have on our financial statements.
