~~EXPLANATORY NOTE~~

Tenneco Inc. (together with its subsidiaries, "Tenneco," the "Company," "we" and "our") is filing this Amendment No. 1 on Form 10-Q/A (the “Form 10-Q/A”) to its Quarterly Report on Form 10- Q for the quarter ended March 31, 2017, originally filed with the Securities and Exchange Commission on May 5, 2017 (the “Original Filing”), to make the certain changes as described below.

In preparing the consolidated financial statements for the quarter ended June 30, 2017, the Company identified deficiencies in its internal control over financial reporting. These deficiencies, when aggregated together, resulted in a material weakness in the Company’s internal control over financial reporting in China as of June 30, 2017. Specifically, the Company did not have people with appropriate authority and experience in key positions in China to ensure adherence to Company policies and US GAAP. Additionally, we did not have adequate international oversight to prevent the intentional mischaracterization of the nature of accounting transactions related to payments received from suppliers by certain purchasing and accounting personnel at the Company’s China subsidiaries.

The material weakness identified as of June 30, 2017 caused us to reevaluate our previous conclusions on internal control over financial reporting as of December 31, 2016, and we have now concluded that the material weakness relating to our internal control over financial reporting in China existed as of December 31, 2016. As a result, we have restated our December 31, 2016 report on internal control over financial reporting. As a result of the material weakness and our restated report on internal control over financial reporting, we have concluded that our disclosure controls and procedures were not effective as of March 31, 2017 and have determined to amend our report on those disclosure controls and procedures.

The material weakness described above resulted in immaterial errors impacting our previously issued consolidated financial statements for the years ended December 31, 2016, 2015 and 2014, each interim and year-to-date period in those respective years, as well as the first quarter of 2017. We evaluated these errors and concluded that they did not, individually or in the aggregate, result in a material misstatement of our previously issued consolidated financial statements and that such financial statements may continue to be relied upon.

This Form 10-Q/A amends the Original Filing to correct the immaterial errors to the consolidated financial statements, arising from the foregoing and an unrelated immaterial error relating to our accrual for certain substrate liabilities, as described in more detail in Note 14 thereto. Revisions to the Original Filing have been made to the following items solely as a result of and to reflect these revisions:

~~Part I, Item 1 - Financial Statements (Unaudited)~~

~~Part I, Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations~~

~~Part I, Item 4 - Controls and Procedures~~

~~Part II, Item 1A - Risk Factors~~

~~Part II, Item 6 - Exhibits~~

As required by Rule 12b-15 under the Securities Exchange Act of 1934, the Company’s principal executive officer and principal financial officer are providing new currently dated certifications. In addition, the Company is filing a new letter from PricewaterhouseCoopers LLP regarding interim financial information. Accordingly, this Form 10-Q/A amends Part II, Item 6 in the Original Filing to reflect the filing of the new certifications and letter.

Except as described above, this Form 10-Q/A does not amend, update or change any other items or disclosures in the Original Filing and does not purport to reflect any information or events subsequent to the filing thereof. As such, this Form 10-Q/A speaks only as of the date the Original Filing was filed, and the Company has not undertaken herein to amend, supplement or update any information contained in the Original Filing to give effect to any subsequent events. Accordingly, this Form 10-Q/A should be read in conjunction with the Company’s filings made with the Securities and Exchange Commission subsequent to the filing of the Original Filing, including any amendment to those filings.

Concurrently with the filing of this Form 10-Q/A, we are also filing an amendment to our Annual Report on Form 10-K for the year ended December 31, 2016. Future Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q will reflect the revisions for financial information included in this Form 10-Q/A and the Form 10-K/A for the year ended December 31, 2016.

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;~~conditions and/or regulatory or legal changes affecting internal combustion engines;

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;

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 conditions, such as currency exchange ~~rate~~and inflation rates, 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;

~~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, and benefit from, 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 fires, 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;~~customers or in the operation of our system, disaster recovery capabilities or business continuity capabilities;

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.

In addition, important factors related to the transaction with Federal-Mogul LLC ("Federal-Mogul") that could cause actual results to differ materially from the expectations reflected in the forward-looking statements, including:

the risk that the transaction with Federal-Mogul pursuant to the Membership Interest Purchase Agreement by and among the Company, Federal-Mogul, American Entertainment Properties Corp., and Icahn Enterprises L.P., may not be completed in a timely manner or at all;

the risk that the benefits of the acquisition of Federal-Mogul, including synergies, may not be fully realized or may take longer to realize than expected; and

the risk that, following the acquisition of Federal-Mogul, the combined company may not complete a separation of its powertrain technology business and its aftermarket & ride performance business (or achieve some or all of the anticipated benefits of such a separation).

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~~2017 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.

FINANCIAL INFORMATION

ITEM 1.FINANCIAL STATEMENTS (UNAUDITED)

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Tenneco Inc.

Results of Review of Financial Statements

We have reviewed the accompanying condensed consolidated balance sheet of Tenneco Inc. and its subsidiaries as of ~~March~~June 30, 2018, and the related condensed consolidated statements of income (loss), comprehensive income (loss) and cash flows for the three-month and six-month periods ended June 30, 2018 and 2017 and the condensed consolidated statements of changes in shareholders' equity for the six-month periods ended June 30, 2018 and 2017, including the related notes (collectively referred to as the “interim financial statements”). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of the Company as of December 31, 2017, and the related ~~condensed~~ consolidated statements of income, comprehensive income, changes in shareholders’ equity and cash flows for the ~~three-month periods~~year then ended ~~March~~(not presented herein), and in our report dated February 28, 2018, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2017, ~~and 2016.~~ is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

These interim financial statements are the responsibility of the Company’s management.

We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our review in accordance with the standards of the ~~Public Company Accounting Oversight Board (United States).~~PCAOB. 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),~~PCAOB, 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, changes in shareholders’ equity and cash flows for the year then ended (not presented herein), and in our report dated February 24, 2017, except for the effects of the revision discussed in Note 16 to the consolidated financial statements, as to which the date is September 8, 2017, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2016, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

(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.~~2017.

In our opinion, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary ~~to present fairly~~for a fair statement of Tenneco Inc.’s results of operations, comprehensive income (loss), 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 unaudited 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.

~~Revision~~Segment Information

In the first quarter of ~~Previously Issued Financial Statements~~

For the periods from April 1, 2013 through March 31, 2017, we identified approximately $34 million in lump sum payments from our suppliers that were incorrectly recorded upon receipt as a reduction to cost of sales. The errors resulted from the intentional mischaracterization by certain purchasing and accounting personnel at2018, the Company’s ~~China subsidiaries~~reportable segments for financial reporting purposes were revised, and now consist of the ~~nature of the accounting transactions related to the payments received from suppliers. These payments should have been deferred~~following three segments: Clean Air, Ride Performance and amortized over the life of the underlying supplier agreements. The deferred amount related to these payments was $29 million at March 31, 2017 and recorded within deferred credit and other liabilities. In addition, we identified an unrelated error of approximately $7 million of substrate liabilities that should have been accrued during the periods from January 1, 2016 through March 31, 2017, understating cost of sales in each of these periods. We evaluated the impact of these items on prior periods under the guidance of SEC Staff Accounting Bulletin (SAB) No. 99, “Materiality” and determined that the amounts were not material to previously issued financial statements. As a result, we have revised and will revise for annual and interim periods in future filings, for certain amounts in the consolidated financial statements in order to correct these errors.Aftermarket. See Note ~~14 in our notes to condensed consolidated financial statements located in Part I Item 1 of this Form 10-Q/A.~~13, Segment Information for further information.

Prepayments and Other

Prepayments and other included ~~$126~~$140 million and ~~$97~~$117 million at ~~March 31, 2017~~June 30, 2018 and December 31, ~~2016,~~2017, respectively, for in-process tools and dies that we are building for our original equipment customers.

Accounts Payable

Accounts payable included ~~$88~~$103 million and ~~$99~~$77 million at ~~March 31, 2017~~June 30, 2018 and December 31, ~~2016,~~2017, respectively, for accrued compensation and ~~$30~~$13 million and ~~$27~~$20 million at ~~March 31, 2017~~June 30, 2018 and December 31, ~~2016,~~2017, respectively, for bank overdrafts at our European subsidiaries.

Redeemable Noncontrolling Interests

(2)	Pending Acquisition of Federal-Mogul

On April 10, 2018, Tenneco entered into a Membership Interest Purchase Agreement (the "Purchase Agreement") with Federal-Mogul LLC ("Federal-Mogul"), American Entertainment Properties Corp. ("AEP"), and Icahn Enterprises L.P. ("IEP"), pursuant to which Tenneco will acquire Federal-Mogul (the “Acquisition”).

Subject to the terms and conditions of the Purchase Agreement, Tenneco will (i) pay to AEP an aggregate amount in cash equal to $800 million (the “Cash Consideration”) and (ii) issue and deliver to AEP an aggregate of 29,444,846 shares (the “Stock Consideration”) of Tenneco's common stock, subject to reduction if Tenneco undertakes a primary offering of common stock prior to the closing of the Acquisition described below, which shall be comprised of: (a) a number of shares of common stock (to be reclassified as Class A Voting Common Stock, par value $0.01, at the closing of the Acquisition (“Class A Common Stock”)) equal to 9.9% of the aggregate number of shares of Class A Common Stock issued and outstanding as of immediately following the closing of the Acquisition, and (b) the balance in shares of newly created Class B Non-Voting Common Stock, par value $0.01 (“Class B Common Stock”).

Until the date that is ten business days prior to the anticipated closing date of the Acquisition, Tenneco may elect to conduct an offering of its common stock in order to raise funds to increase the Cash Consideration. Such offering may include up to 7,315,490 shares of common stock that would otherwise have been issued to AEP in connection with the Acquisition. Each share sold in such an offering will decrease the number of shares of common stock issuable to AEP by one share, so the total number of shares of common stock to be issued in connection with the Acquisition will not change if Tenneco undertakes such an offering.

The completion of the Acquisition is subject to certain customary closing conditions and the Purchase Agreement contains customary representations, warranties and covenants by each party that are subject, in some cases, to specified exceptions and qualifications contained in the Purchase Agreement.

Following the closing of the Acquisition, Tenneco has agreed to use its reasonable best efforts to pursue the separation of the combined company’s powertrain technology business and its aftermarket & ride performance business into two separate, publicly traded companies in a spin-off transaction that is expected to be treated as a tax-free reorganization for U.S. federal income tax purposes (the "Spin-off" and, together with the Acquisition, the "Transaction").

Advisory costs associated with the pending acquisition were $18 million and $31 million for the three and six month periods ended June 30, 2018, respectively, and have been recognized as a component of selling, general and administrative expenses in the condensed consolidated statements of income (loss).

the fair value hierarchy.

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~~$662 million and ~~$725~~$749 million at ~~March 31, 2017~~June 30, 2018 and December 31, ~~2016~~2017, respectively. We have classified ~~$682~~$658 million and ~~$571~~$634 million as level 2 in the fair value hierarchy at ~~March 31, 2017~~June 30, 2018 and December 31, ~~2016~~2017, 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~~June 30, 2018 and December 31, ~~2016~~2017.

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~~Currency 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~~currency forward contracts as part of currency gains (losses) within cost of sales in the consolidated statements of ~~income.~~income (loss). The fair value of foreign ~~exchange~~currency 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 both June 30, 2018 and at December 31, ~~2016, respectively.~~2017.

Cash-settled Share Swap Transactions — We selectively use cash-settled share swaps to reduce market risk associated with our deferred liabilities. These equity compensation liabilities increase as our stock price increases and decrease as our stock price decreases. In contrast, the value of the swap agreement moves in the opposite direction of these liabilities, allowing us to fix a portion of the liabilities at a stated amount. As of June 30, 2018, we had hedged our deferred liability related to approximately 250,000 common share equivalents. The fair value of the equity swap agreement is recorded in other current assets in the consolidated balance sheet. The fair value of our equity swap agreement was a net asset position of $2 million and $4 million at June 30, 2018 and December 31, 2017, respectively.

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~~14, 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~~sheet. As of ~~March 31, 2017~~June 30, 2018 and December 31, ~~2016~~2017, ~~respectively.~~these plans were in an overfunded position and shown under other assets, other on our condensed consolidated balance sheets. At ~~March 31, 2017~~June 30, 2018, 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~~June 30, 2018, we have guaranteed ~~$31~~$29 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~~$19 million and $11 million at ~~both March 31, 2017~~June 30, 2018 and December 31, ~~2016~~2017, respectively, and were classified as notes ~~payable.~~payable recorded in short-term debt in our condensed consolidated balance sheets. Financial instruments received from original equipment (OE) customers and not redeemed totaled $9$21 million and $5$10 million at ~~March 31, 2017~~June 30, 2018 and December 31, ~~2016, respectively.~~2017, respectively, and were classified as other current assets in our consolidated balance sheets. We classify financial instruments received from our customers as other current assets, recorded in prepayments and other, 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 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~~do 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 $1 million and $2 million at ~~both March 31, 2017~~June 30, 2018 and December 31, ~~2016.~~2017, respectively.

One of our subsidiaries in ~~Brazil~~Spain is required by law to maintain a cash deposit with ~~the~~a financial institution to guarantee the maximum estimated loss related to a tax audit until a settlement is reached. The cash deposit required was less than $1 million which has been classified as restricted cash on the Tenneco Inc. consolidated balance sheet at ~~March~~both June 30, 2018 and December 31, 2017. As of December 31, 2017, there was a similar cash deposit required for one of our subsidiaries in Brazil for approximately $1 million. The audit was closed in 2018 and the Brazil subsidiary has no restricted cash balance as of June 30, 2018.

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 ~~$33~~$27 million and ~~$34~~income tax benefit of $8 million in the three month periods ended ~~March 31,~~June 30, 2018 and 2017, ~~and March 31, 2016,~~ respectively.

The tax benefit recorded in the second quarter of 2017 included a net tax benefit of $1$50 million ~~primarily~~ relating to an antitrust settlement accrual.

We reported income tax expense of $52 million and $25 million in the ~~first quarter~~six month periods ended June 30, 2018 and 2017, ~~adoption of Accounting Standard Update 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.~~respectively. The tax expense recorded in the first ~~quarter~~six months of ~~2016~~2018 included tax benefits of $7 million relating to acquisition charges and $2 million of tax expense for changes in the toll tax as discussed below. The tax expense recorded in the first six months of 2017 included a net tax benefit of $3$49 million primarily relating to ~~tax adjustments to uncertain tax positions~~an antitrust settlement accrual.

On December 22, 2017, the Tax Cuts and ~~prior year~~Jobs Act ("TCJA") was enacted into U.S. law, which, among other provisions, lowered the corporate income tax ~~estimates.~~rate effective January 1, 2018 from 35% to 21%, and implemented significant changes with respect to U.S. tax treatment of earnings originating from outside the U.S. Many of the provisions of TCJA are subject to regulatory interpretation and U.S. state conforming enactment. The IRS issued Notice 2018-26 on April 2, 2018, which provided additional guidance to assist taxpayers in computing the toll tax. Based on the new guidance, a $2 million discrete charge was recorded in income tax expense for the second quarter of 2018. We will continue to refine our estimates throughout the measurement period provided for in SEC Staff Accounting Bulletin 118, or until our accounting is complete.

Our losses in various foreign taxing jurisdictions represented sufficient negative evidence to require us to maintain a full valuation allowance against certain of our net deferred tax assets. We evaluate our deferred income taxes quarterly to determine if valuation allowances are required or should be adjusted. 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. If recent operational improvements continue in certain of our foreign subsidiaries, we believe it is reasonably possible that sufficient positive evidence may be available to release all, or a portion, of its valuation allowance in the next twelve months. This may result in a one-time tax benefit of up to $54 million, primarily related to Spain.

We believe it is reasonably possible that up to ~~$17~~$7 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)~~(6)	Accounts Receivable Securitization and Factoring Programs

We securitize or factor some of our accounts receivable on a limited recourse basis in the U.S. and Europe. As servicer under these accounts receivable securitization and factoring programs, we are responsible for performing all accounts receivable administration functions for these securitized and factored 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~~$10 million and $30 million, recorded in short-term debt, at ~~March~~June 30, 2018 and December 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.

On December 14, 2017, we entered into a new accounts receivable factoring program in the U.S. with a commercial bank. Under this program, we sell receivables from one of our U.S. OE customers at a rate that is favorable versus our senior credit facility. This arrangement is uncommitted and provides for cancellation by the commercial bank with no less than 30 days prior written notice. The amount of outstanding third-party investments in our accounts receivable sold under this program was $122 million and $107 million at June 30, 2018 and December 31, 2017, respectively.

We also ~~securitize~~factor receivables in our European operations with regional banks in ~~Europe. The arrangements to securitize receivables in~~ Europe ~~are provided~~ under ~~seven~~various separate ~~facilities provided by various financial institutions in each of the foreign jurisdictions.~~facilities. The commitments for these arrangements are generally for one year, but some may be ~~canceled~~cancelled 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 sold under programs in Europe was ~~$209~~$255 million and $~~160~~218 million at ~~March 31, 2017~~June 30, 2018 and December 31, ~~2016~~2017, respectively. Certain programs in Europe have deferred purchase price arrangements with the banks. We received cash to settle the deferred purchase price for $32 million and $27 million in the three month periods ended June 30, 2018 and 2017, respectively, and $66 million and $49 million in the six month periods ended June 30, 2018 and 2017, respectively.

If we were not able to securitize or factor receivables under either the U.S. or European ~~securitization~~ programs, our borrowings under our revolving credit agreement might increase. These accounts receivable securitization and factoring 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 U.S. and European accounts receivable factoring programs, we transfer accounts ~~receivables~~receivable 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 U.S. and European ~~securitization~~factoring programs approximates the fair value of such receivables. We recognized $1$1 million interest expense in each of the three month periods ended ~~March 31,~~June 30, 2018 and 2017, and ~~2016~~$2 million in each of the six month periods ended June 30, 2018 and 2017, relating to our U.S. securitization program. In addition, we recognized a loss of $2 million and $1 million in ~~each of~~ the three month periods ended ~~March 31,~~June 30, 2018 and 2017, respectively, and ~~2016~~$4 million and $2 million in the six month periods ended June 30, 2018 and 2017, respectively, on the sale of trade accounts receivable in our U.S. and European accounts receivable ~~securitization~~factoring programs, representing the discount from book values at which these receivables were sold to our banks. The remaining loss on receivables recognized is unrelated to the aforementioned factoring programs. The discount rate varies based on funding costs incurred by our banks, which averaged approximately two percent during both the first six months of 2018 and 2017 for the European programs and three percent and two percent during the first six months of 2018 and 2017, respectively, for the US program.

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.

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.~~regulations. As of ~~March 31, 2017~~June 30, 2018, we have the obligation to remediate or contribute towards the remediation of certain sites, including one Federal Superfund site. At ~~March 31, 2017, our~~Our aggregated estimated share of environmental remediation costs for all these sites on a discounted basis was approximately ~~$15~~$17 million at June 30, 2018, of which $2$3 million is recorded in other current liabilities and ~~$13~~$14 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~~weighted-average discount rate used was ~~2.5~~2.6 percent. The undiscounted value of the estimated remediation costs was ~~$18~~$21 million. Our expected payments of environmental remediation costs are estimated to be approximately $2 million in 2018, $3 million in 2019, $1 million in each year beginning ~~2017~~2020 through ~~2021~~2022 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"~~(“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, and are subject to similar claims filed by other plaintiffs, in the United ~~States.~~States and Canada. 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~~U.S. 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. Typically, exposure for follow-on actions in Canada is less than the exposure for U.S. follow-on actions.

~~Antitrust law investigations,~~conditional leniency from the DOJ in 2014 and discussions during the third quarter of 2017 following the appointment of a special settlement master in the civil ~~litigation, and related matters often continue for several years and can result~~putative class action cases pending against Tenneco and/or certain of its competitors in ~~significant penalties and liability. We intend~~the U.S., Tenneco continues to vigorously defend ~~the Company~~itself and/or take ~~other~~ actions to minimize ~~our~~its potential ~~exposure. In light~~exposure to matters pertaining to the global antitrust investigation, including engaging in settlement discussions when it is in the best interests of the ~~many uncertainties~~company and ~~variables involved, we cannot estimate~~its stockholders. For example, in October 2017, Tenneco settled an administrative action brought by Brazil's competition authority for an amount that was not material. Additionally, in February 2018, Tenneco settled civil putative class action litigation in the ~~ultimate impact~~United States brought by classes of indirect purchasers, end-payors and auto dealers. No other classes of plaintiffs have brought claims against Tenneco in the United States. Based upon those earlier developments, including settlement discussions, Tenneco established a reserve of $132 million in its second quarter 2017 financial results for settlement costs that ~~these~~were probable, reasonably estimable, and expected to be necessary to resolve Tenneco’s antitrust matters ~~may have on our company. Further, there can be no assurance that~~globally, which primarily involves the ~~ultimate~~ resolution of ~~these~~civil suits and related claims. Of the $132 million reserve that was established, $64 million has been paid life-to-date resulting in a remaining reserve of $68 million as of June 30, 2018, which is recorded in other current liabilities. While Tenneco continues to cooperate with certain competition agencies investigating possible violations of antitrust laws relating to products supplied by Tenneco, and the company may be subject to other civil lawsuits and/or related claims, no amount of this reserve is attributable to matters ~~will not have~~with the DOJ or the EC, and no such amount is expected based on current information.

Our reserve for antitrust matters is based upon all currently available information and an assessment of the probability of events for those matters where Tenneco can make a ~~material~~reasonable estimate of the costs to resolve such outstanding matters. Tenneco’s estimate involves significant judgment, given the number, variety and potential outcomes of actual and potential claims, the uncertainty of future rulings and approvals by a court or other authority, the behavior or incentives of adverse ~~effect on our consolidated financial position, results~~parties or regulatory authorities, and other factors outside of ~~operations or liquidity.~~

~~Other Legal Proceedings, Claims and Investigations~~

~~We are also~~the control of Tenneco. As a result, Tenneco’s reserve may change 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 cashactual costs ~~or charges to earnings if any of these matters are resolved on unfavorable terms.~~may vary. 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 that any such change in the ~~legal proceedings, claims or investigations currently pending against us~~reserve will have ~~any~~a material adverse impact on our annual consolidated financial position, results of operations or liquidity.

~~In addition, for~~Other Legal Proceedings, Claims and Investigations

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.

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. For example, in July 2017 a complaint was filed against us in federal district court in Chicago, Illinois alleging that we misappropriated a third party's trade secrets in connection with certain of our ride control products.

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" and in this paragraph, 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. With respect to the trade secret claim described above, we are in the process of evaluating the claim but, at this stage of the case and given the inherent uncertainly of litigation, we are unable to estimate whether a loss is reasonably possible. While we do not believe that this litigation will have a material adverse effect on our annual consolidated financial position, results of operations or liquidity, we cannot assure you that this will be the case.

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 condensed consolidated balance ~~sheet.~~sheets.

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~~years, inclusive of $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~~did not repurchase any shares ~~for $16 million~~ through this program in the ~~three~~six months ended ~~March 31, 2017.~~June 30, 2018.

~~(11)~~(12)	New Accounting Pronouncements

Adoption of New Accounting Standards

In March 2017, the Financial Accounting Standards Board (“FASB”) issued ~~Accounting Standard Update~~ASU 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,~~costs.

Prior year net pension and postretirement (benefits) costs of $(2) million and $7 million for ~~annual~~the three and six month periods ~~beginning after December 15,~~ended June 30, 2017, respectively, have been reclassified from selling, general, and ~~interim periods within those annual periods.

In November 2016, the FASB issued ~~Accounting Standard Update~~ASU 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,~~We retrospectively adopted this standard in 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~~first quarter of ~~this guidance is not expected~~2018 with no material impact.

In October 2016, the FASB issued ~~Accounting Standard Update~~ASU 2016-16, Income Taxes - Intra Entity Transfers of Assets Other Than Inventory (Topic 740). The ~~new~~ standard ~~changes~~changed 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~~did not change the current accounting for the income taxes related to transfers of inventory. ~~For public business entities,~~We adopted this standard on January 1, 2018 using the ~~standard is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within those annual periods.~~modified retrospective method.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), an amendment on ~~employees' behalf~~revenue recognition. The amendment in this update created Topic 606, Revenue from Contracts with Customers, and superseded 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 superseded the cost guidance in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts, and created a 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 ~~withheld shares are presented~~those goods or services. We adopted Topic 606 on January 1, 2018, using the modified retrospective method. The cumulative effect of the adoption was recognized as ~~financing activities. Tenneco elected~~an increase to ~~apply~~retained earnings (accumulated deficit) of $1 million on January 1, 2018.

Accounting Standards Issued But Not Yet Adopted

In February 2018, the FASB issued ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220). The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Consequently, the amendments allow for an election to eliminate the stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires the effect of a change in ~~presentation retrospectively~~tax laws or rates be included in income from continuing operations is not affected. The amendments in this update also require certain disclosures about stranded tax effects.

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.

~~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.

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.

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 retrospectively revised to reflect our current segmentation. These changes also resulted in changes to the Company's reporting units. The Company allocated goodwill to its new reporting ~~segments.~~units in the first quarter of 2018, using a relative fair value approach, assessed potential goodwill impairment for all reporting units immediately before and immediately after the reallocation, and determined that no impairment existed.

~~(14)~~(15)	~~Revision of Previously Issued Financial Statements~~Revenue

~~For~~In May 2014, the ~~periods~~FASB issued an amendment on revenue recognition. The amendment created Topic 606, Revenue from ~~April 1, 2013 through March 31, 2017, we identified approximately $34 million~~Contracts with Customers, and supersedes the revenue recognition requirements in ~~lump sum payments from our suppliers that were incorrectly recorded upon receipt as a reduction to cost of sales. These payments should have been deferred and amortized over~~ASC Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance throughout the ~~life~~Industry Topics of the ~~underlying supplier agreements.~~Codification. In addition, the amendment supersedes the cost guidance in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts, and created new Subtopic 340-40, Other Assets and Deferred Costs-Contracts with Customers. The ~~deferred credit balance~~core principle of ASC 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.

We adopted ASC Topic 606 Revenue from Contracts with Customers and all the related amendments ("new revenue standard") on January 1, 2018, using the modified retrospective method. The cumulative effect of the adoption was recognized as an increase to ~~these payments was $29~~retained earnings (accumulated deficit) of $1 million and ~~$23 million at March 31, 2017 and December 31, 2016, respectively.~~

~~In addition, we identified approximately $7 million in cost of sales that should have been accrued in prior periods for substrate liabilities, impacting~~ the ~~periods from~~changes made to our consolidated January 1, ~~2016 through March 31, 2017.~~

We evaluated the impact of these items on prior periods under the guidance of SEC Staff Accounting Bulletin (SAB) No. 99, “Materiality” and determined that the amounts were not material to previously issued financial statements.

We also evaluated the impact of correcting these items through a cumulative adjustment to our financial statements and concluded that based on the guidance within SEC SAB No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements” it was appropriate to revise our previously issued financial statements to reflect this correction. As a result, we have revised and will revise for annual and interim periods in future filings, for certain amounts in the consolidated financial statements and related notes in order to correct these errors, which are described further below.

~~The following tables present the impact of this revision on our condensed consolidated~~2018 opening balance ~~sheets as of December 31, 2016 and March 31, 2017, our condensed consolidated statements of income, comprehensive income, cash flows and changes in shareholders' equity~~sheet for the ~~three months ended March 31, 2017 and 2016:~~adoption of ASC Topic 606 were as follows:

Revenue from contracts with customers

We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. While the majority of the contracts we enter into with original equipment (“OE”) and aftermarket customers are long-term supply arrangements, the performance obligations are established by the enforceable contract, which is generally considered to be the purchase order but in some cases could be the delivery release schedule. The purchase order, or related delivery release schedule, is of a duration less than one year. As such, the Company applies the practical expedient in ASC paragraph 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one year or less, for which work has not yet been performed.

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.

Performance Obligations

The Company generates revenue through the design, manufacture, and sale of clean air and ride performance systems and products for light vehicle, commercial truck, off-highway and other applications. We recognize revenue for sales to our OE and aftermarket customers when transfer of control of the related good or service has occurred. Revenue from most of OE and aftermarket goods and services is transferred to customers occurs at a point in time. Contract terms with certain of our OE customers results in products and services being transferred over time due to the customized nature of some of our products together with contractual provisions in certain of our customer contracts that provide us with an enforceable right to payment for performance completed to date.

(Unaudited)

Under typical terms, we do not have the right to consideration until the time of shipment from our plants or distribution center or the time of delivery to our customers. The timing of revenue recognition from products transferred to customers over time may be slightly accelerated compared to our right to consideration at the time of shipment or delivery. We invoice the customer once transfer of control has occurred and we have a right to payment. Our typical payment terms vary based on the customer and the type of goods and services in the contract. The period of time between invoicing and when payment is due is not significant. Amounts billed and due from our customers are classified as receivables on the balance sheet. As our standard payment terms are less than one year, we have elected the practical expedient under ASC paragraph 606-10-32-18 to not assess whether a contract has a significant financing component.

Original Equipment

In a typical arrangement with an OE customer, purchase orders are issued for pre-production activities, which consist of engineering, design and development, tooling, and prototypes for the manufacture and delivery of component parts. We have concluded that these activities are not in the scope of ASC Topic 606 and for that reason, the Company has not made any changes to how it accounts for reimbursable pre-production costs, currently accounted for as a cost reduction. Generally, in connection with the sale of exhaust systems to certain OE 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 are “passed through” to the customer at our cost, plus a small margin. Since we take title to the substrate inventory and have responsibility for both the delivery and quality of the finished product including the substrates, the revenues and related expenses are recorded gross. Revenues recognized for substrate sales were $621 million and $541 million for the three month periods ended June 30, 2018 and 2017, respectively, and $1,273 million and $1,088 million for the six month periods ended June 30, 2018 and 2017, respectively.

Due to the highly customized nature of certain finished components for our OE customers, revenue is recognized over time, consistent with the transfer of control of an asset with limited alternative use, and the Company having an enforceable right to payment for performance completed to date. We consider an input measure (e.g., costs incurred to date relative to total estimated costs at completion) as a fair measure of progress for the recognition of over time revenue associated with these customized parts. A cost measure best depicts the means of transfer of goods to the customer, which occurs as we incur costs to fulfill contracts. Total revenue recognized over time for such customized parts totaled less than $1 million and $2 million for the three and six month periods ended June 30, 2018, respectively.

Prices for our OE customer base are generally fixed on the purchase order and allocation of consideration between goods and services is rare as the highly customized parts are considered sold at their standalone selling price. If an occasion arose whereby a finished component was not deemed sold at its standalone selling price, consideration would be allocated among different performance obligations based on an estimate, most likely cost plus margin, of the standalone selling price of each distinct good or service in the contract.

Aftermarket

Our aftermarket customers take delivery of finished components, which are recognized as revenue at the time the customer takes possession, which is usually at the time of shipment. This determination is based on applicable shipping terms as well as the consideration of other indicators, including timing of when the Company has a present right to payment, when physical possession of products is transferred to customers, when the customer has the significant risks and rewards of ownership of the asset, and any provisions in contracts regarding customer acceptance. While unit prices are generally fixed, for certain of our aftermarket customers, we provide for variable consideration, typically in the form of promotional incentives and returns at the time of sale. Expected values are based upon the contractual terms of the incentives and historical experience with returns. In most cases, we are able to derive the expected value of variable consideration at a level to conclude it is probable that a significant revenue reversal will not occur in future periods. In cases where the high threshold for recognition is not established, such amounts will be constrained and recognized when the uncertainty underlying the constraint is resolved. Certain aftermarket contracts with customers include terms and conditions that provide for inventory adjustments that result in a customer right of return that should be accounted for on a gross basis. For these contracts we have recorded a refund liability and inventory return asset.

Contract Balances

Contract assets primarily relate to the Company’s rights to consideration for work completed but not billed at the reporting date on contracts with customers. The contract assets are transferred to the receivables when the rights become unconditional. Contract liabilities primarily relate to contracts where advance payments or deposits have been received, but performance obligations have not yet been met, and therefore, revenue has not been recognized.

Disaggregation of revenue

Revenue from contracts with customers is disaggregated by product lines, as it depicts the nature and amount of the Company’s revenue that is aligned with the Company's key growth strategies. In the following table, revenue is disaggregated accordingly:

Changes to policies related to revenue recognition under ASC Topic 606

Upon the adoption of ASC Topic 606, there was a change in the pattern of revenue recognition for certain customized parts. Under ASC Topic 605, revenue was recognized for these customized parts when title and risk of loss passed to the customers under the terms of our arrangements with those customers, which was usually at the time of shipment from our plants or distribution centers. As a result of the adoption, the revenue from these contracts will now be recognized over time because the customized parts are considered to be assets with limited alternative use and the Company has an enforceable right to payment for work completed to date. The Company considers the costs incurred (input method) as a fair measure of progress for the over time recognition of revenue associated with these customized parts.

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~~included in Item I of this quarterly report on ~~page 6.~~Form 10-Q and the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2017.

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~~also engineer, manufacture, market and distribute leading, brand-name products to a diversified and global aftermarket customer base. Both original equipment (OE) vehicle designers and manufacturers and the repair and replacement markets, or aftermarket, are served 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~~six of the top 10 car models produced for sale in Europe and ~~eight~~nine of the top 10 light truck models produced for sale in North America for ~~2016.~~2017. Our aftermarket customers are comprised of full-line and specialty warehouse distributors, retailers, jobbers, installer chains and car dealers. As of December 31, ~~2016,~~2017, we operated 9192 manufacturing facilities worldwide and employed approximately ~~31,000~~32,000 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~~second quarter of ~~2017,~~2018, light vehicle production was up ten percent in South America, up 14 percent in India, up four percent in Europe, and up nine percent in China compared to the second quarter of 2017. Light vehicle production was down three percent in North America when compared to the second quarter of 2017. For the first six ~~percent in Europe, seven percent in both China and India and 19~~months of 2018, light vehicle production was up 11 percent in South America, up 12 percent in India, up two percent in Europe, and up three percent in China compared to the first ~~quarter~~six months of ~~2016.~~2017. Light vehicle production was down 29three percent in ~~Australia in the first quarter of 2017~~North America when compared to the first ~~quarter~~six months of ~~2016.~~2017.

~~As announced on February 7, 2017, we made an organizational change in our reportable segments effective with~~In the first quarter of ~~2017. Our Clean~~2018, we changed our reportable segments. The new reporting segments (Clean Air, ~~and~~ Ride Performance ~~product lines in India, which had been reported~~and Aftermarket) align with how the Chief Operating Decision Maker allocates resources and assesses performance against the Company’s key growth strategies. Costs related to other business activities, primarily corporate headquarter functions, are disclosed separately from the three operating segments as ~~part of the Europe, South America and India segments, are now reported with their respective product lines in the Asia Pacific segments.~~"Other." Prior period ~~segment information~~segmentation has been revised to ~~reflect~~conform to current year presentation.

On April 10, 2018, we entered into a Membership Interest Purchase Agreement (the “Purchase Agreement”) with Federal-Mogul LLC ("Federal-Mogul"), American Entertainment Properties Corp. (“AEP”), and Icahn Enterprises L.P. (“IEP”), pursuant to which we will acquire Federal-Mogul (the “Acquisition”). Following the closing of the Acquisition, we agreed to use our ~~new reporting segments.~~reasonable best efforts to pursue the separation of the combined company’s powertrain technology business and its aftermarket & ride performance business into two separate, publicly traded companies in a spin-off transaction that is expected to be treated as a tax-free reorganization for U.S. federal income tax purposes (the “Spin-Off” and, together with the Acquisition, the “Transaction”). See Note 2, Pending Acquisition of Federal-Mogul to our condensed consolidated financial statements.

With the Acquisition expected to close in the fourth quarter of 2018 and the Spin-Off expected to occur in the second half of 2019, we anticipate incurring additional expenses related to the cost of both transactions.

Results of Operations

For the Three Months Ended June 30, 2018 and 2017

Total revenues for the ~~first~~second quarter of ~~2017~~2018 were ~~$2,292~~$2,537 million, up ~~seven~~nine percent from ~~$2,136~~$2,317 million in the ~~first~~second quarter of ~~2016~~2017 on strong global light vehicle and commercial truck, off-highway and other 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~~$113 million, or ~~nine~~six percent, from ~~$1,626~~$1,776 million to ~~$1,769~~$1,889 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.new platforms.

Cost of sales (exclusive of depreciation and amortization): Cost of sales for the ~~first~~second quarter of ~~2017~~2018 was ~~$1,931~~$2,159 million, or ~~84.2~~85.1 percent of sales, compared to ~~$1,770~~$1,949 million, or ~~82.9~~84.1 percent of sales in the ~~first~~second quarter of ~~2016.~~2017.

~~Results from Operations~~

~~The tables below reflect our~~Table of Contents

Overview of Net Sales and Operating Revenues

An element of the revenues ~~for the first quarters of 2017 and 2016. We show the component~~ of our ~~OE revenue represented by~~Clean Air segment is derived from substrate sales. Substrates are porous ceramic filters coated with a catalyst - typically, precious metals such as platinum, palladium and rhodium. 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~~substrates, but rather, they 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.

We present these substrate sales separately 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.

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,~~Finally, 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~~base period of the ~~base period~~comparisons for measuring the effects of currency ~~during 2017 on our operations.~~in the subsequent year. We believe investors find this information useful in understanding period-to-period comparisons in our revenues.

Included in the results for the first six months of 2018 were costs related to our restructuring activities, acquisition advisory costs, pre-closing costs, a warranty charge, an environmental charge, the associated tax impacts on the aforementioned costs, and other unfavorable discrete tax items. The total impact of these items decreased earnings per diluted share by $1.40. We reported net income attributable to Tenneco Inc. of $56 million or $1.05 per diluted common share for the first six months of 2017. Included in the results for the first six months of 2017 were costs related to our restructuring activities, charges related to pension derisking and the acceleration of restricted stock vesting, cost related to our refinancing activities, a warranty settlement and an antitrust settlement accrual, which were partially offset by positive impact from the gain on sale of an unconsolidated JV. The total impact of these items, as adjusted for their related tax impacts, decreased earnings per diluted share by $2.29.

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~~the second quarter of 2018 and 2017, we paid ~~an initial~~a quarterly dividend of $0.25 per share, or $12 million and $13 ~~million.~~million, respectively. In the first six months of 2018 and 2017, we paid a quarterly dividend of $0.25 per share, or $25 million and $26 million, respectively. 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.

On May 12, 2017, we completed a refinancing of our senior credit facility by entering into an amendment and restatement of that facility. The amended and restated credit agreement enhances financial flexibility by increasing the size and extending the term of its revolving credit facility and term loan facility, and by adding Tenneco Automotive Operating Company Inc. as a co-borrower under the revolver credit facility. The amended and restated credit agreement also adds foreign currency borrowing capability and permits the joinder of our foreign and domestic subsidiaries as borrowers under the revolving credit facility in the future. If any foreign subsidiary of ours is added to the revolving credit facility as a borrower, the obligations of such foreign borrower will be secured by the assets of such foreign borrower, and also will be secured by the assets of, and guaranteed by, the domestic borrowers and domestic guarantors as well as certain foreign subsidiaries of ours in the chain of ownership of such foreign borrower. The amended and restated credit facility consists of a $1,600 million revolving credit facility and a $400 million term loan A facility, which replaced our former $1,200 million revolving credit facility and $264 million term loan A facility, respectively. As of June 30, 2018, the senior credit facility provides us with a total revolving credit facility of $1,600 million and had a $380 million balance outstanding under the term loan A facility, both of which will mature on May 12, 2022.

Acquisition of Federal-Mogul LLC

Tenneco signed a definitive agreement on April 10, 2018, to acquire Federal-Mogul, a global supplier to original equipment manufacturers and the aftermarket. Tenneco intends to separate the combined businesses into two independent, publicly traded companies through a tax-free spin-off to shareholders that will establish an aftermarket and ride performance company and a powertrain technology company.

The Federal-Mogul acquisition is expected to close early in the fourth quarter of 2018, subject to regulatory and shareholder approvals and other customary closing conditions, with the separation expected to occur in the second half of 2019. The transaction is expected to be value accretive with run-rate earnings synergies of at least $200 million and one-time working capital synergies of at least $250 million within 24 months of closing.

On July 23, Tenneco announced that its Board of Directors has selected Brian J. Kesseler and Roger J. Wood as the chief executive officers of the two new companies. Kesseler will become chairman and CEO of the aftermarket and ride performance company, which will be headquartered in Lake Forest, Illinois, and Wood will become chairman and CEO of the new powertrain technology company, which will be headquartered in the Detroit, Michigan area. Immediately upon closing of the Federal-Mogul acquisition, and prior to separation, Kesseler and Wood will serve as co-CEOs of Tenneco Inc., leading their respective businesses, while preparing each to become a stand-alone entity and helping facilitate a smooth spin-off. During this period, the co-CEOs will report to the Tenneco Board of Directors.

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.~~2017. Please see that disclosure for further information. Additionally, revenue assumptions for the ~~second~~third quarter and full year ~~2017~~2018 are based on current and projected customer production schedules as well as aggregate industry production, which includes IHS Automotive ~~April 2017~~July 2018 global light vehicle production forecasts, Power Systems Research (PSR) ~~April 2017~~July 2018 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. Certain elements of the restructuring and related expenses, legal settlements and other unusual charges we incur from time to time cannot be forecasted accurately. In this respect, we are not able to forecast EBIT (and the related margins) on a forward-looking basis without unreasonable efforts on account of these factors and the difficulty in predicting GAAP revenues (for purposes of a margin calculation) due to variability in production rates and volatility of precious metal pricing in the substrates that we pass through to our customers. 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~~There have been no changes to our critical ~~areas where estimates are required.~~accounting policies since December 31 2017, except for the following:

Revenue Recognition

We ~~recognize~~account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers, which we adopted on January 1, 2018, using the modified retrospective method. The Company recorded a transition adjustment as of January 1, 2018, which increased retained earnings (accumulative deficit) by $1 million related to these arrangements. Please refer to Note 15, Revenue, in our condensed consolidated financial statements for ~~sales to~~further discussion of the adoption of this standard.

Revenue is recognized for our original equipment and aftermarket customers when ~~title and risk of loss passes to the customers~~performance obligations under the terms of a contract are satisfied, which generally occurs with the transfer of control of our products. For most of our products, transfer of control occurs upon shipment or delivery, however, a limited number of our customer arrangements for our highly customized products with ~~those customers, which~~no alternative use provide us with the right to payment during the production process. As a result, for these limited arrangements, under the new revenue standard, revenue is ~~usually at~~recognized as goods are produced and control transfers to the ~~time of shipment from our plants or distribution centers.~~ customer.

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~~$1,273 million and ~~$510~~$1,088 million for the first ~~three~~six months of ~~2017~~2018 and ~~2016,~~2017, 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

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

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.

At June 30, 2018, of the ~~$1,200~~$1,600 million available under the revolving credit facility, we had unused borrowing capacity of ~~$783~~$1,322 million with ~~$417~~$278 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

Table 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.Contents

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 plus, without duplication, the domestic receivable program amount, net of unrestricted cash and cash equivalents up to $250 million, divided by consolidated EBITDA, each 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 ~~calculated~~achieved for the ~~first~~second quarter of ~~2017,~~2018, are as follows (the ratios in the table reflect the revisions made to the financial statements in this Form 10-Q/A; these revisions would result in immaterial changes to the actual ratios reported to our lenders in prior periods, with such changes being less than .05 and .36 to the leverage ratio and interest coverage ratio, respectively):follows:


	Quarter Ended		Quarter Ended
	March 31, 2017		June 30, 2018
	Required	Actual	Required	Actual
Leverage Ratio (maximum)	3.50	1.62	3.50	1.79
Interest Coverage Ratio (minimum)	2.75	15.38	2.75	10.84

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.~~May 12, 2022. The amended and restated senior credit facility provides us with the flexibility not to exclude certain otherwise excludable charges incurred in any relevant period from the calculation of the leverage and interest coverage ratios for such period. As of June 30, 2018, we elected not to exclude a total of $93 million of excludable charges. Had these charges been excluded, the leverage ratio and the interest ratio would have been 1.59 and 12.19, respectively, as of June 30, 2018.

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;~~May 12, 2017; 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		Aggregate Senior Note Maximum Amount
	(Millions)		(Millions)
Greater than or equal to 3.25x			$	20
Greater than or equal to 3.0x	$	20	$	100
Greater than or equal to 2.5x	$	100	$	225
Greater than or equal to 2.0x	$	200
Less than 2.0x	no limit
Less than 2.5x			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; (viii) disposition of assets; and ~~(viii)~~(ix) 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.

Recently Committed Senior Credit Facility. In connection with the execution of the Purchase Agreement, as discussed in Note 2, Pending Acquisition of Federal-Mogul, we entered into a debt commitment letter, pursuant to which JPMorgan Chase Bank, N.A. and Barclays Bank PLC (the "Commitment Parties") have committed to provide a $4.9 billion senior credit facility, a portion of which will be used to finance the Cash Consideration portion of the purchase price and replace the Company’s existing senior credit facilities and certain senior facilities at Federal-Mogul. In June 2018, the Commitment Parties completed the syndication of the commitments for the $4.9 billion senior credit facility among a group of banks and other financial institutions. The new senior credit facility will consist of a five-year $1.5 billion revolving credit facility, a five-year $1.7 billion term loan A facility and a seven-year $1.7 billion term loan B facility. The new credit facilities will be secured on a senior basis by substantially all assets of the Company on a pari passu basis with Federal-Mogul’s existing secured notes, and will be guaranteed by certain material domestic subsidiaries. The commitment to provide financing is subject to specified limited conditions.

As of ~~March 31, 2017~~June 30, 2018, 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 5~~³/8 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.~~financial covenants.

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 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.~~Securitization and Factoring Programs. We securitize or factor some of our accounts receivable on a limited recourse basis in the U.S. and Europe. As servicer under these accounts receivable securitization and factoring programs, we are responsible for performing all accounts receivable administration functions for these securitized and factored 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~~$10 million and $30 million, recorded in short-term debt, at ~~March 31, 2017~~June 30, 2018 and December 31, ~~2016~~2017, respectively.

We also ~~securitize~~factor receivables in our European operations with regional banks in ~~Europe. The arrangements to securitize receivables in~~ Europe ~~are provided~~ under ~~seven~~various separate ~~facilities provided by various financial institutions in each of the foreign jurisdictions.~~facilities. The commitments for these arrangements are generally for one year, but some may be ~~canceled~~cancelled 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 sold under programs in Europe was ~~$209~~$255 million and ~~$160~~$218 million at ~~March~~June 30, 2018 and December 31, 2017, respectively. Certain programs in Europe have deferred purchase price arrangements with the banks. We received cash to settle the deferred purchase price for $32 million and ~~December 31, 2016~~,$27 million in the three month periods ended June 30, 2018 and 2017, respectively, and $66 million and $49 million for the six month periods ended June 30, 2018 and 2017, respectively.

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 U.S. and European accounts receivable factoring 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 U.S. and European ~~securitization~~factoring programs approximates the fair value of such receivables. We recognized $1 million interest expense in each of the three month periods ended ~~March 31,~~June 30, 2018 and 2017, and ~~2016~~$2 million in each of the six month periods ended June 30, 2018 and 2017, relating to our U.S. securitization program. In addition, we recognized a loss of $2 million and $1 million in ~~each of~~ the three month periods ended ~~March 31,~~June 30, 2018 and 2017, respectively, and ~~2016,~~$4 million and $2 million in the six month periods ended June 30, 2018 and 2017, respectively, on the sale of trade accounts receivable in our U.S. and European accounts receivable ~~securitization~~factoring 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 both the first ~~three~~six months of ~~both~~2018 and 2017, respectively, for the European programs and ~~2016.~~three percent and two percent during the first six months of 2018 and 2017, respectively, for the US program.

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~~$19 million and $11 million at ~~both~~ ~~March~~June 30, 2018 and December 31, 2017, ~~and~~ ~~December 31, 2016~~ respectively, and were classified as notes ~~payable.~~payable recorded in short-term debt. Financial instruments received from OE customers and not redeemed totaled $9$21 million and $5$10 million at ~~March~~June 30, 2018 and December 31, 2017, respectively, and ~~December 31, 2016, respectively.~~were classified as other current assets. We classify financial instruments received from our customers as other current assets, recorded in prepayments and other, 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.~~

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~~liability position of less than $1 million at ~~March 31, 2017~~June 30, 2018 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~~June 30, 2018. All contracts in the following table mature in ~~2017.~~2018.

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~~,June 30, 2018, we had ~~$740~~$738 million of principal amounts 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~~had $661 million of principal amounts 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~~June 30, 2018 was about ~~100~~95 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$7 million.

Equity Prices

We also utilize an equity swap arrangement to offset changes in liabilities related to the equity market risks of our arrangements for deferred compensation and restricted stock unit awards. Gain or losses from changes in fair value of these equity swaps are generally offset by the losses or gains on the related liabilities. In 2017, we entered into an equity swap agreement with a financial institution. We selectively use cash-settled share swaps to reduce market risk associated with our deferred liabilities. These equity compensation liabilities increase as our stock price increases and decrease as our stock price decreases. In contrast, the value of the swap agreement moves in the opposite direction of these liabilities, allowing us to fix a portion of the liabilities at a stated amount. As of June 30, 2018, we had hedged deferred liability related to approximately 250,000 common share equivalents.

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$16 million and $7$14 million for the ~~three~~six month periods ended ~~March 31,~~June 30, 2018 and 2017, ~~and 2016,~~ respectively. Matching contributions vest immediately. Defined benefit replacement contributions fully vest on the employee’s third anniversary of employment.

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 amended (the Exchange Act)) as of the end of the quarter covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer ~~have~~ concluded that, due to athe material weakness in our internal control over financial reporting previously identified and described ~~below,~~more fully under Item 9A in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, the Company’s disclosure controls and procedures were not effective as of ~~March 31, 2017~~June 30, 2018 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.

Internal Controls Surrounding the Accounting for Supplier Payments

A material weakness (as defined in Rule 12b-2 under the Exchange Act) is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement in our annual or interim financial statements will not be prevented or detected on a timely basis.

~~During~~As previously identified and described more fully under Item 9A in the ~~quarter~~Company’s Annual Report on Form 10-K for the year ended ~~June 30,~~December 31, 2017, the Company identified deficiencies that, when aggregated together, resulted in a material weakness in the Company’s internal control over financial reporting in China. Specifically, the Company did not have people with appropriate authority and experience in key positions in China to ensure adherence to Company policies and US GAAP. Additionally, we did not have adequate international oversight to prevent the intentional mischaracterization of the nature of accounting transactions related to payments received from suppliers by certain purchasing and accounting personnel at the Company’s China subsidiaries. The material weakness continued to exist as of the end of the period covered by this Quarterly Report.

The material weakness ~~identified as~~resulted in the revision of ~~June 30, 2017 caused us to reevaluate our previous conclusions on internal control over~~the consolidated financial ~~reporting~~statements as of December 31, 2016, 2015 and we have now concluded that the material weakness relating to our internal control over financial reporting existed as of December 31, 2016. As a result, we have restated our December 31, 2016 report on internal control over financial reporting. As a result of the material weakness2014, each interim and our restated report on internal control over financial reporting, we have reevaluated the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2017 and concluded they were not effective to provide reasonable assurance 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 because of the identification of a material weakness in our internal control over financial reporting described above.

The Company determined that the identified misstatements resulting from the intentional mischaracterizations discussed above were not material to the financial results reported in any prior interim or annualyear-to-date period but would be material if corrected as an out-of-period adjustment. As a result, the Company has amended its Annual Report on Form 10-K for the year ended December 31, 2016 and its Quarterly Report on Form 10-Q for the quarter ended March 31, 2017 to correct the immaterial errors to the consolidated financial statements, as described in more detail in Notes 16 and 14 to the consolidated financial statements included in those ~~reports, respectively.~~

respective years, and the first interim period in 2017. Additionally these control deficiencies could result in the misstatement of the relevant account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or ~~detected.~~detected, our management has determined that these control deficiencies constitute a material weakness.

Remediation Plan for Material Weakness in Internal Control over Financial Reporting

The Audit Committee engaged an independent legal firm to investigate these transactions and it concluded that such mischaracterizations were intentional. In particular, certain China personnel created accounting documentation for certain supplier transactions that was inconsistent with the substance of the transactions. With respect to these circumstances, the Company ~~is taking~~has taken action ~~with respect~~ to dismiss the individuals who ~~have~~ engaged in intentional ~~misconduct,~~misconduct.

Under the oversight of the Audit Committee and ~~will take further actions~~ as ~~appropriate.~~

As part of our commitment to strengthening our internal ~~controls~~control over financial reporting, we ~~are implementing various~~implemented a number of actions during the second half of 2017, including (i) strengthening the China accounting staff with personnel ~~actions~~who have significant experience in U.S. and ~~will initiate other related remedial actions under the oversight of the Audit Committee, including~~

~~implementing~~international financial reporting; (ii) providing additional training for China accounting and purchasing ~~personnel,~~personnel; and (iii) augmenting ~~international accounting~~the process with additional oversight ~~with~~from qualified personnel in the ~~United States~~U.S. and ~~Europe,~~Europe. Oversight activities have revealed the need for increased frequency in communication and ~~enhancing oversight controls at~~additional transparency in the ~~Company’s China locations around adherence by Company personnel to policies regarding payments received from suppliers.~~monitoring mechanisms put in place. Accordingly, we concluded that this material weakness had not yet been remediated as of June 30, 2018.

We will continue to monitor the effectiveness of these and other processes, procedures and controls and make any further changes management determines appropriate.

Changes in Internal Control Over Financial Reporting

There ~~were~~have been no changes in our internal control over financial reporting during the quarter ended ~~March 31, 2017,~~June 30, 2018, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 1.LEGAL PROCEEDINGS

Note 8, Environmental Matters, Legal Proceedings and Product Warranties, in our condensed consolidated financial statements located in Part I Item 1 of this Form 10-Q is incorporated herein by reference.

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. On April 10, 2018, we entered into a Membership Interest Purchase Agreement (the “Purchase Agreement”), pursuant to which we will acquire (the “Acquisition”) Federal-Mogul LLC ("Federal-Mogul").

Subject to the terms and conditions of the Purchase Agreement, we will (i) pay to American Entertainment Properties Corp. (“AEP”) an aggregate amount in cash equal to $800 million (the “Cash Consideration”) and (ii) issue and deliver to AEP an aggregate of 29,444,846 shares (the “Stock Consideration”) of common stock, par value $0.01 (“Common Stock”), subject to reduction if Tenneco undertakes a primary offering of Common Stock prior to the closing of the Acquisition as described below, which shall be comprised of: (a) a number of shares of Common Stock (to be reclassified as Class A Voting Common Stock, par value $0.01, at the closing of the transaction (“Class A Common Stock”)) equal to 9.9% of the aggregate number of shares of Class A Common Stock issued and outstanding as of immediately following the closing of the Acquisition, and (b) the balance of shares of newly created Class B Non-Voting Common Stock, par value $0.01 (“Class B Common Stock”).

Until the date that is ten business days prior to the anticipated closing date of the Acquisition, Tenneco may elect to conduct an offering of its Common Stock in order to raise funds to increase the Cash Consideration. Such offering may include up to 7,315,490 shares of Common Stock that would otherwise have been issued to AEP in connection with the Acquisition. Each share sold in such an offering will decrease the number of shares of Common Stock issuable to AEP by one share, so the total number of shares of Common Stock to be issued in connection with the Acquisition will not change if Tenneco undertakes such an offering.

Except ~~as set forth~~for the addition of the new risk factors related to the Acquisition below, 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.~~

~~We have identified a material weakness~~2017. The risks described herein or in our ~~internal control over~~Annual Report on Form 10-K are not the only risks facing us. 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, financial ~~reporting~~condition and operating results, or the extent to which ~~could, if not remediated, result in material misstatements in our financial statements.~~

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended. As disclosed in Part I, Item 4, management identified a material weakness in internal control over financial reporting related to the accounting for payments received from suppliers by certain purchasing and accounting personnel at the Company’s China subsidiaries. A material weakness (as defined in Rule 12b-2) is a deficiency,any such risk factor or combination of ~~deficiencies, in internal control over~~risk factors may impact our business, financial ~~reporting, such~~condition and operating results.

Risks Relating to the Transaction

There can be no assurance that ~~there~~we will successfully complete our acquisition of Federal-Mogul on the terms or timetable currently proposed or at all.

If the Acquisition is not completed, our business, financial condition and results of operations may be materially adversely affected and the market price of our Common Stock may decline significantly, particularly to the extent that the current market price reflects a ~~reasonable possibility~~market assumption that ~~a material misstatement~~the Acquisition will be completed. If the completion of annual or interim financial statements will not be prevented or detected on a timely basis. As a result of this material weakness, management concluded that internal control over financial reporting was not effective based on criteria set forththe Acquisition is delayed, including by the ~~Committee~~receipt of ~~Sponsoring Organizations~~an acquisition proposal, our business, financial condition and results of operations may be materially adversely affected.

In addition, Federal-Mogul and AEP have the ability to terminate the Purchase Agreement in certain circumstances. If the Purchase Agreement is terminated, we would not realize the anticipated benefits of the ~~Treadway Commission~~Acquisition or the Spin-Off (defined below), but we would remain liable for significant transaction costs incurred, including legal, accounting and financial advisory fees. Accordingly, our business, financial condition and results of operations may be materially adversely affected. In addition, in “Internal Control-An Integrated Framework (2013).” This material weakness resulted in a revision to our consolidated financial statements as of December 31, 2016, 2015 and 2014, each quarterly and year-to-date periods in those respective years, andcertain circumstances, if the first quarterly period in 2017. We are actively engaged in developing and implementing a remediation plan designed to address this material weakness. If remedial measures are insufficient to address the material weakness, or if additional material weaknesses in internal control are discovered or occur in the future, our consolidated financial statements may contain material misstatements andPurchase Agreement is terminated, we could be required to ~~restate~~pay AEP a termination fee equal to $200 million.

Any of the foregoing, or other risks arising in connection with the failure of or delay in completing the Acquisition, including the diversion of management’s attention from pursuing other opportunities and the constraints in the Purchase Agreement on our ability to make significant changes to our ongoing business during the pendency of the transaction, could have a material adverse effect on our business, financial condition and results of operations.

Table of Contents

The Acquisition is subject to certain customary closing conditions, including the adoption of the amended and restated certificate of incorporation and approval of the issuance of the Stock Consideration by our stockholders at the special meeting (or an adjournment or postponement thereof), that, if not satisfied, will result in the Acquisition not being completed, which may result in material adverse consequences to our business, financial condition and results of operations.

The completion of the Acquisition is subject to certain customary closing conditions, that, if not satisfied, will prevent the Acquisition from being completed, including among others: (i) (a) the adoption of the amended and restated certificate of incorporation and (b) the approval by our stockholders of the issuance of the Stock Consideration by our stockholders at a special meeting of our stockholders; (ii) the filing of the amended and restated certificate of incorporation of the Company with the Secretary of State for the State of Delaware; and (iii) the approval for the listing of the Class A Common Stock (including shares of Class A Common Stock issuable upon conversion of the Class B Common Stock to be issued to AEP as Stock Consideration) on the New York Stock Exchange, subject to official notice of issuance.

If the Acquisition is not completed, our business, financial condition and results of operations could be materially adversely affected by the loss of employees and customers, the costs incurred in pursuing the transaction, and potential reputational harm. There can be no assurance that the conditions to closing will be satisfied or waived, or that other events will not intervene to delay or prevent the completion of the Acquisition.

We must obtain governmental and regulatory approvals prior to completing the Acquisition, which, if delayed or not granted, may delay or jeopardize the full benefits of the Acquisition.

The governmental and regulatory agencies from which we are seeking these approvals have broad discretion in administering the applicable governing regulations. As a condition to their approval of the transactions contemplated by the Purchase Agreement, those agencies may impose requirements, limitations or costs or require divestitures or place restrictions on the conduct of our business following the transaction. The required approvals may not be obtained or the required conditions to the Acquisition may not be satisfied, or, even if the required approvals are obtained and the conditions to the completion of the Acquisition are satisfied, the terms, conditions and timing of such approvals are uncertain.

There can be no assurance that the requisite governmental and regulatory approvals will be received in a timely fashion or at all. Any delay in completing the Acquisition, including a delay in receipt of the necessary governmental or regulatory approvals, may have a material adverse effect on our business, financial condition and results of operations, and such delay could cause us not to realize some or all of the benefits that we expect to achieve if the Acquisition were to be successfully completed within the expected time frame.

In addition, if we fail to obtain any necessary governmental or regulatory approval at or prior to the time the closing is required to occur pursuant to the Purchase Agreement, we may elect to consummate the Acquisition without such approval. As a result, we may not be able to acquire certain assets, businesses or entities of Federal-Mogul at the closing of the Acquisition, in which case AEP will hold such assets, businesses or entities separately for the benefit of Tenneco, until such time where such assets, businesses or entities can be transferred to Tenneco. This could have a material adverse effect on our business, financial condition and results of operations, and could cause us not to realize some or all of the benefits that we expect to achieve if the Acquisition were to be successfully completed within the expected time frame. In addition, we could be subject to fines, penalties, costs, and other adverse action undertaken by applicable governmental and regulatory agencies.

We may fail to realize all of the anticipated benefits of the Acquisition or those benefits may take longer to realize than expected. We and, following the Spin-off, each separate company may also encounter significant difficulties in integrating the business of Federal-Mogul.

The success of the transaction will depend, in part, on our ability (and the ability of each separate company following the Spin-off) to realize the anticipated benefits of the Acquisition and Spin-off (the “Transaction”) and on our (and each separate company’s) ability to integrate Federal-Mogul’s business in an effective and efficient manner, which is a complex, costly and time-consuming process. The integration process may disrupt business and, if we are unable to successfully integrate Federal-Mogul’s business, we (and each separate company) could fail to realize the anticipated benefits of the Transaction. The failure to meet the challenges involved in the integration process and realize the anticipated benefits of the Transaction could cause an interruption of, or a loss of momentum in, our operations and could have a material adverse effect on our (and each separate company’s) business, financial condition and results of operations.

In addition, the integration of Federal-Mogul may result in material unanticipated challenges, expenses, liabilities, competitive responses and loss of customers and other business relationships. Additional integration challenges include:

diversion of management’s attention to integration matters;

difficulties in achieving anticipated cost savings, synergies, business opportunities and growth prospects from the Transaction;

difficulties in the integration of operations and systems;

Table of Contents

difficulties in conforming standards, controls, procedures and accounting and other policies, business cultures and compensation structures;

difficulties in the assimilation of employees;

difficulties in managing the expanded operations of a significantly larger and more complex company;

challenges in attracting and retaining key personnel;

the impact of potential liabilities Tenneco may be inheriting from Federal-Mogul; and

coordinating a geographically dispersed organization.

Many of these factors are outside of our control and could result in increased costs, decreases in the amount of anticipated revenues and diversion of management’s time and energy, each of which could adversely affect our (and each separate company’s) business, financial condition and results of operations.

In addition, even if the integration of Federal-Mogul’s business is successful, we (and each separate company) may not realize all of the anticipated benefits of the Transaction, including the synergies, cost savings, or sales or growth opportunities. These benefits may not be achieved within the anticipated time frame, or at all. Further, additional unanticipated costs may be incurred in the integration process. All of these factors could cause reductions in earnings per share, decrease or delay the expected accretive effect of the transaction and negatively impact the price of shares of our Common Stock (or each separate company’s stock). As a result, it cannot be assured that the Transaction will result in the realization of the anticipated benefits and potential synergies.

Our current stockholders will have reduced ownership and voting interests following the Acquisition and will exercise less influence over management.

Holders of our Common Stock currently possess all voting rights with respect to the election of our board of directors and on other matters affecting us. Upon the closing of the Acquisition, we will issue an amount of Class A Common Stock to AEP equal to 9.9% of our Class A Common Stock issued and outstanding as of immediately following the closing of the Acquisition. Accordingly, our stockholders will experience an immediate dilution and have proportionally less voting power in the combined company following the transaction, and as a result, may have less influence on our management and policies. Additionally, upon the closing of the Acquisition, we will issue the balance of the Stock Consideration in shares of Class B Common Stock. As a result, our stockholders will have proportionately less ownership than they have now.

In addition, prior to the closing of the Acquisition, assuming the price of our common stock is above $54.6785, we may elect, or if we do not elect, AEP may direct us in certain circumstances, to conduct a primary offering of common stock in order to raise funds to increase the Cash Consideration by the amount of certain of the proceeds of such offering. Such offering may include up to 7,315,490 shares of common stock that would otherwise have been issued to AEP in connection with the Acquisition. If such an offering is undertaken, the Cash Consideration will be increased by an amount equal to the number of shares sold in such offering multiplied by $54.6785 and the Stock Consideration will be decreased by the number of shares sold in such offering. In other words, the total number of shares to be issued in connection with the Acquisition will not change if Tenneco undertakes such an offering. However, Tenneco stockholders existing immediately prior to the offering (and prior to the closing of the Acquisition), will have proportionally less voting power following the closing of the offering (and subsequently, following the closing of the Acquisition). However, Tenneco stockholders will not experience any incremental economic dilution as a result of such offering as the total number of shares of common stock to be issued in connection with the Acquisition will not be increased above 29,444,846.

We are unable to predict the potential effects of the issuance of the Stock Consideration on the trading activity and market price of our common stock. We have granted certain registration rights to AEP for the resale of the shares issued in connection with the Acquisition. These registration rights would facilitate the resale of such shares into the public market, and any such resale would increase the number of shares of our Class A Common Stock available for public trading. Sales of a substantial number of shares of our Class A Common Stock in the public market, or the perception that such sales might occur, could have a material adverse effect on the price of our Class A Common Stock.

If AEP transfers any shares of its Class B Common Stock to a third-party, the shares of Class B Common Stock so transferred will automatically convert in shares of Class A Common Stock and as a result, our current stockholders will experience further dilution and a proportionate reduction in voting power.

The Purchase Agreement contains provisions that could discourage a potential third-party from considering or proposing a transaction with us.

The Purchase Agreement contains “no solicitation” provisions that, subject to limited exceptions, restrict our ability to solicit, initiate, induce or knowingly facilitate or encourage the submission or announcement of any proposal for the acquisition of our stock or assets. In addition, AEP generally has an opportunity to offer to modify the terms of the Purchase Agreement in response to any acquisition proposal before our board of directors may terminate the Purchase Agreement to

Table of Contents

accept a superior proposal. The Purchase Agreement further provides that, upon termination of the Purchase Agreement under specified circumstances, we will be required to pay AEP a termination fee equal to $200 million.

These provisions could discourage a potential third-party that might have an interest in acquiring all or a significant portion of our stock or assets from considering or proposing such an acquisition or may result in a potential third-party proposing to pay a lower per share price to our stockholders than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable in certain circumstances.

If the Purchase Agreement is terminated and we seek another business combination, we may not be able to negotiate a transaction with another party on terms comparable to, or better than, the terms of the Purchase Agreement.

The market price of our Class A Common Stock may be affected by factors different from those affecting the shares of our Common Stock prior to completion of the Acquisition.

Our historical business differs from that of Federal-Mogul. Accordingly, our results of operations and the market price of our Common Stock following the completion of the Acquisition may be affected by factors that differ from those that previously affected the independent results of operations of each of Tenneco and Federal-Mogul and the market price of our existing common stock.

We may not generate sufficient financing to fund the purchase price for the Acquisition.

We have entered into a debt commitment letter, pursuant to which JPMorgan Chase Bank, N.A. and Barclays Bank PLC have committed to provide a $4.9 billion senior credit facility. The new senior credit facility will consist of a five-year $1.7 billion Term Loan A, a seven-year $1.7 billion Term Loan B and a five-year $1.5 billion revolving credit facility, a portion of which will be used to finance the Cash Consideration portion of the purchase price and replace our existing senior credit facilities and certain senior credit facilities at Federal-Mogul.

There can be no assurance that the foregoing transactions, or any other financing transactions that we may pursue, will generate sufficient funds to finance the Acquisition. The obligations of the lenders under the debt commitment letter are subject to specified limited conditions, and we cannot assure you that these conditions will be met. The closing of the Acquisition is not conditioned on our ability to obtain sufficient financing to consummate the Acquisition.

The planned Spin-Off following the transaction is subject to various risks and uncertainties and may not be completed in accordance with the expected plans or anticipated timeline, or at all, and will involve significant time and expense, which could disrupt or adversely affect our business.

Following the completion of the transaction, we intend to separate the combined company’s businesses to create two separate, publicly traded companies in a spin-off transaction (the “Spin-Off”). The Spin‑Off is intended to be treated as a tax-free reorganization for U.S. federal income tax purposes. There can be no assurance that the Spin-Off will be completed at all or that the Spin-Off will be tax-free for U.S. federal income purposes. We expect that the process of completing the proposed Spin-Off will be time‑consuming and involve significant costs and expenses, which may be significantly higher than what we currently anticipate and may not yield a benefit if the Spin-Off is not completed. Planning for the Spin-Off is in its early stages, and we may encounter unforeseen impediments to the completion of the Spin-Off that render the Spin-Off impossible or impracticable.

If the Spin-Off is not completed, our business, financial condition and results of operations may be materially adversely affected and the market price of our Common Stock may decline significantly, particularly to the extent that the current market price reflects a market assumption that the Spin-Off will be completed. If the completion of the Spin-Off is delayed, including by the receipt of an acquisition proposal, our business, financial condition and results of operations may be materially adversely affected.

The pendency of the Transaction could adversely affect our business, financial results and operations.

The announcement and pendency of the Transaction could cause disruptions and create uncertainty surrounding our business and affect our relationships with our customers, suppliers and employees.

As a result of the Transaction, some customers, suppliers or strategic partners may terminate their business relationship with us or Federal Mogul. Potential customers, suppliers or strategic partners may delay entering into, or decide not to enter into, a business relationship with us or Federal-Mogul because of the Transaction. If customer or supplier relationships or strategic alliances are adversely affected by the Transaction, our (and each separate company’s after the Spin-Off) business, financial condition and results of operations following the Acquisition or Spin-Off could be adversely affected.

We are dependent on the experience and industry knowledge of our officers and other key employees to execute our business plans. Our success after and in implementing the Transaction depends in part upon the ability to retain key management personnel and other key employees. Current and prospective employees of Tenneco and Federal-Mogul may experience uncertainty about their roles with the combined company following the Acquisition or either separate company following the Spin-Off, or concerns regarding operations following the Transaction, any of which may have an adverse effect

Table of Contents

on the ability to attract or retain key management and other key personnel. Accordingly, no assurance can be given that we (or each separate company after the Spin-Off) will be able to attract or retain key management personnel and other key employees until the Transaction is completed or following the Transaction to the extent that we have previously been able to attract or retain such employees.

In addition, we have diverted, and will continue to divert, significant management resources to complete the Transaction, which could adversely impact our ability to manage existing operations or pursue alternative strategic transactions, which could adversely affect our business, financial condition and results of operations.

The Spin-Off may not achieve some or all of the anticipated benefits.

We may not realize some or all of the anticipated strategic, financial, operational or other benefits from the Spin-Off. As independent publicly-traded companies, the two companies will be smaller, less diversified companies with a narrower business focus. As a result, the two companies may be more vulnerable to changing market conditions, which could result in increased volatility in their cash flows, working capital and financing requirements and could have a material adverse effect on the respective business, financial condition and results of operations of each company. Further, there can be no assurance that the combined value of the common stock of the two companies will be equal to or greater than what the value of our common stock would have been had the Spin-Off not occurred.

Table of Contents

If the Acquisition and Spin-Off are completed, the combined company prior to the Spin-Off and each separate company following the Spin-Off may underperform relative to our expectations.

Following completion of the Transaction , the combined company or each separate company may not be able to maintain the growth rate, levels of revenue, earnings or operating efficiency that we and Federal-Mogul have achieved or might achieve separately. The failure to do so could have a material adverse effect on our business, financial condition and results of operations or, following the Spin-Off, the business, financial condition and results of operations of each separate company.

We have incurred, and will continue to incur, significant transaction costs in connection with the Transaction that could adversely affect our results of operations.

Whether or not we complete the Transaction, we have incurred, and will continue to incur, significant costs in connection with the Transaction and integrating the business and operations of Federal-Mogul with our business and operations. We also expect we will incur fees and expenses in connection with the related financing transactions, including the debt financing and any primary offering. We may also incur additional unanticipated costs in the separation processes. These could adversely affect our business, financial condition and results of operations, or the business, financial condition and results of operations of each company following the Spin-Off, in the period in which such expenses are recorded, or the cash flows, in the period in which any related costs are actually paid.

Furthermore, we and each company following the Spin-Off may incur material restructuring charges in connection with integration activities or the Spin-Off, which may adversely affect operating results for the period in which such expenses are recorded, or cash flows in the period in which any related costs are actually paid.

The fairness opinion we obtained from our financial ~~results.~~advisor will not reflect changes in circumstances subsequent to the date of the fairness opinion.

Barclays Capital, our financial advisor in connection with the Acquisition, has delivered to our board of directors its opinion dated as of April 9, 2018, that as of such date, and based upon and subject to the factors and assumptions set forth therein, the consideration to be paid to AEP pursuant to the Purchase Agreement was fair from a financial point of view to us. The opinion does not reflect changes that may occur or may have occurred after the date of the opinion, including changes to the operations and prospects of Tenneco or Federal-Mogul, changes in general market and economic conditions or regulatory or other factors. Any such changes, or changes in other factors on which the opinion is based, may materially alter or affect the relative values of Tenneco or Federal-Mogul. The fairness opinion will not be updated to reflect changes in circumstances subsequent to the date of the fairness opinion.

(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~~second quarter of ~~2017.~~2018. These purchases reflect shares withheld upon vesting of restricted stock for tax withholding ~~obligations as well as shares repurchased through our share repurchase program.~~obligations. 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~~years, including $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~~did not repurchase any shares ~~for $16 million~~ through this program in the ~~three~~six months ended ~~March 31, 2017.~~June 30, 2018.
