The accompanying Condensed Consolidated Financial Statements are those of Hexcel Corporation.  Refer to Note 1 to the consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2018 for a discussion of our significant accounting policies. S ignificant changes to our accounting policies subsequent to the filing of our Form 10-K, relate solely to the adoption of Topic 842, Leases, are discussed below in Recent Accounting Pronouncements as well as in Note 4.

Basis of Presentation

The accompanying Condensed Consolidated Financial Statements have been prepared from the unaudited accounting records of Hexcel pursuant to rules and regulations of the Securities and Exchange Commission (“SEC”) and in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information.  Certain information and footnote disclosures normally included in financial statements have been omitted pursuant to rules and regulations of the SEC. In the opinion of management, the Condensed Consolidated Financial Statements include all normal recurring adjustments as well as any non-recurring adjustments necessary to present fairly the statement of financial position, results of operations and cash flows for the interim periods presented.  The Condensed Consolidated Balance Sheet as of December 31, 2018 was derived from the audited 2018 consolidated balance sheet.  Interim results are not necessarily indicative of results expected for any other interim period or for the full year.  These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 2018 Annual Report on Form 10-K.

Investments in Affiliated Companies

We have a 50% equity investment in Aerospace Composites Malaysia Sdn. Bhd. (“ACM”) and a 25% equity investment in Hexcut Services.  These investments are accounted for using the equity method of accounting.      

Recent Accounting Pronouncements

In February 2016, the FASB issued Accounting Standards Update No. 2016-02 (ASU 2016-02), Leases (Topic 842). This standard requires lessees to recognize a right of use asset and lease liability on the balance sheet for all leases, with the exception of leases with a duration of one year or less. We adopted the provisions of this standard on January 1, 2019, using the modified transition method which allows companies to recognize existing leases at the adoption date without requiring comparable presentation. As a result of the adoption of this standard we recognized approximately $50 million of right of use assets and related liabilities for operating leases that existed prior to January 1, 2019. These right of use assets were recorded in noncurrent assets, and the related liabilities were recorded in other accrued liabilities and other noncurrent liabilities. See Note 4 - Leases, for more details.

In August 2018 the FASB issued Accounting Standards Update No. 2018-14 (ASU 2018-14 ), Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20) , which amends the current disclosure requirements regarding defined benefit pensions and other post retirement plans , and allows for the removal of certain disclosures, while adding certain new disclosure requirements. This standard is effective for fiscal years beginning after December 15, 2020 and allows for early adoption. We do not expect this new standard to have a significant impact to our disclosures.

   Total shares underlying stock options of 0.3 million and 0.2 million, respectively, were excluded from the computation of diluted net income per share for the three months ended March 31, 2019 and March 31, 2018 , as they were anti-dilutive.  

Note 4 — Leases

The Company regularly enters into operating leases for certain buildings, equipment, parcels of land, and vehicles. As of January 1, 2019, we adopted the provisions of ASC 842, accounting for leases.  Accordingly, we capitalized all agreements with terms for more than one year, where a right of use asset was identified. In connection with the adoption of ASC 842 on January 1, 2019 we elected certain practical expedients available under ASC 842-10-65-1 that provide certain concessions to ease the burden of transition, such as the treatment of indirect lease costs, and service contracts which may contain embedded leases. In addition, we elected certain expedients not related to the transition, such as the election to capitalize lease and non-lease components of an agreement as a single component for purposes of simplicity, with the exception of those related to equipment and machinery.

Generally, amounts capitalized represent the present value of minimum lease payments over the term, and the duration is equivalent to the base agreement, however, in certain instances management used certain assumptions when determining the value and duration of certain leases.  These assumptions include, but are not limited to, the probability of renewing a lease term, certain future events impacting lease payments, as well as fair values not explicit in an agreement. Such assumptions impacted the duration of many of our building leases, as well as certain of our equipment leases.

In determining the lease renewal, management considered the need and ability to substitute a given asset, as well as certain conditions such as related contractual obligations to our customers (i.e. a contractual obligation of a customer requiring certain manufacturing proximities). In determining fair value management considered the stand alone value of an asset in an ordinary market as well as incurring certain costs to terminate an agreement.  Most of our leases do not include variable payments but contain

8

scheduled escalations. Any lease payments tied to certain future indexes are adjusted on a go forward basis as those index es become known .

At March 31, 2019, we had approximately $61.4 million of right of use assets recorded in other non-current assets, and $61.8 million of related liabilities, $50.3 of which was included in other non-current liabilities with the remainder in other current liabilities. The weighted average of the remaining lease terms was approximately 8 years.

We discount the future lease payments of our leases using the prevailing rates extended to us by our lenders relevant to the period of inception. These rates are comprised of LIBOR plus a stated spread less a component related to collateralization.  The rates are relative to the duration of the lease at inception and the country to which the lease agreement pertains to.  The weighted average interest rate used in calculating the fair values listed above was 2.5%.

The following table lists the schedule of cash payments related to right of use assets by year:

Operating lease expense recognized during the quarter ending March 31, 2019, relating to right of use assets, was $2.9 million, and was recorded in cost of goods sold as well as in operating expenses, in our condensed consolidated statements of operations. Expense related to operating leases which have a duration of a year or less were not material for the same period. Finance leases at March 31, 2019, were immaterial.

Note 5 — Retirement and Other Postretirement Benefit Plans

We maintain qualified and nonqualified defined benefit retirement plans covering certain current and former U.S. and European employees, retirement savings plans covering eligible U.S. and U.K. employees and certain postretirement health care and life insurance benefit plans covering eligible U.S. retirees. We also participate in a union sponsored multi-employer pension plan covering certain U.S. employees with union affiliations.

9

All costs related to our pensions are included as a component of operating income in our consolidated statements of operations. For the three months ended March 31, 2019 and 2018, amounts unrelated to service costs were a benefit of $0.8 million and $1.1 million, respectively.  

Contributions

We generally fund our U.S. non-qualified defined benefit retirement plans when benefit payments are incurred.  We have contributed approximately $0.2 million in the first three months of 2019 to cover unfunded benefits.  We expect to contribute a total of $0.9 million in 2019 to cover unfunded benefits.  We contributed $0.1 million to our U.S. non-qualified defined benefit retirement plans during the quarter ended March 31, 2018.

We contributed $1.2 million and $1.6 million to our European defined benefit retirement plans in the three months ended March 31, 2019 and 2018, respectively.  We plan to contribute approximately $5.0 million during 2019 to our European plans.

Amounts contributed in connection with our postretirement plans, were immaterial for both the three months ended March 31, 2019 and March 31, 2018. We periodically fund our postretirement plans to pay covered expenses as they are incurred. We expect to contribute less than $0.5 million in 2019 to cover unfunded benefits.

10

In 2017, the Company issued $400 million in aggregate principal amount of 3.95% Senior Unsecured Notes due in 2027. The interest rate on these senior notes may be increased 0.25% each time a credit rating applicable to the notes is downgraded. Conversely, such increases would be reversed should the credit rating be subsequently upgraded. The maximum rate is 5.95%. The effective interest rate for three months ended March 31, 2019 was 3.88% inclusive of approximately a 0.25% benefit of treasury locks. Based on quoted prices the fair value of the senior notes due in 2027 was $400.3 million at March 31, 2019.

In 2015, the Company issued $300 million in aggregate principal amount of 4.7% Senior Unsecured Notes due in 2025. The interest rate on these senior notes may be increased by 0.25% each time a credit rating applicable to the notes is downgraded. Conversely, such increases would be reversed should the credit rating be subsequently upgraded. The maximum rate is 6.7%.  The effective interest rate for the three months ended March 31, 2019 was 4.83%. Based on quoted prices, the fair value of the notes due in 2025 was $314.1 million at March 31, 2019.

The Company has a revolving credit facility (the “Facility”) that allows up to $700 million of borrowings. The Facility matures in June 2021. The interest rate for the Facility at March 31, 2019 was LIBOR + 1.25%. The interest rate ranges from LIBOR + 0.875% to a maximum of LIBOR + 1.875%, depending on the Company’s leverage ratio.     

The Facility contains financial and other covenants, including, but not limited to, restrictions on the incurrence of debt and the granting of liens, as well as the maintenance of an interest coverage ratio and a leverage ratio. In accordance with the terms of the Facility, we are required to maintain a minimum interest coverage ratio of 3.50 (based on the ratio of EBITDA, as defined in the Facility Agreement, to interest expense) and may not exceed a maximum leverage ratio of 3.50 (based on the ratio of total debt to EBITDA) throughout the term of the Facility. In addition, the Facility contains other terms and conditions such as customary representations and warranties, additional covenants and customary events of default.

As of March 31, 2019, total borrowings under the Facility were $414.0 million, which approximates fair value due to its revolving nature. The Facility permits us to issue letters of credit up to an aggregate amount of $40 million. Outstanding letters of credit reduce the amount available for borrowing under our Facility. As of March 31, 2019, there were no outstanding letters of credit under the Facility, resulting in undrawn availability under the Facility as of March 31, 2019 of $286.0 million. The weighted average interest rate for the Facility was 4.17% for the three months ended March 31, 2019.

In 2016, we entered into a € 60 million term loan.  The loan has two tranches of which the first tranche for € 25 million has a rate of Euribor +1.2% and a final maturity date of June 30, 2023, and a second tranche for € 35 million has a rate of Euribor +1.25% with a final maturity date of June 30, 2024. The loans are payable in annual installments that began on June 30, 2017, for the first tranche, and beginning on June 30, 2019, for the second. There is a zero percent floor on the Euribor. Amounts outstanding under this loan at March 31, 2019 were $59.4 million which approximates fair value under the market approach.      

Note 7 — Derivative Financial Instruments

Interest Rate Swap and Interest Lock Agreements

         As of March 31, 2019, the Company had interest rate swaps, having a combined notional value of $50.0 million, that swap floating rate obligations for fixed rate obligations   at an average rate of 1.09% against LIBOR in U.S. dollars. Both swaps mature in September 2019. The swaps are accounted for as cash flow hedges of our floating rate bank loan. To ensure the swaps were highly

11

effective, all of the critical terms of the swaps matched the terms of the bank loan. The fair value of the interest rate swaps was an asset of $0. 3 million   at March 31, 2019 and $0.6 million at December 31, 2018 . 

At March 31, 2019 we had  i nterest rate swaps related to European debt obligations which had a combined notional value of approximately €52.9 million. These derivatives swapped floating rate obligations for fixed rate obligations at a weighted average rate of 0.51% against Euribor in Euros.  The swaps amortize through the final maturities of the obligations, on June 30, 2023 and June 30, 2024, in annual installments. The derivatives are accounted for as cash flow hedges of the floating rate term loans.  To ensure the swaps were highly effective, all of the critical terms of the swap matched the terms of the bank loans.  The fair value of the interest rate swaps was a liability of $0.7 million   at March 31, 2019, and   $0.5 million at December 31, 2018.

The Company had treasury lock agreements to protect against unfavorable movements in the benchmark treasury rate related to the issuance of our 3.95% Senior Unsecured Notes. These hedges were designated as cash flow hedges therefore any change in fair value was recorded as a component of other comprehensive income. As part of the issuance of our senior notes, we net settled these derivatives and therefore the previously deferred gains recorded in other comprehensive income will be released to interest expense over the life of the senior notes. The effect of these treasury locks reduced the effective interest rate on the 2017 senior notes by approximately 0.25%.  

Foreign Currency Forward Exchange Contracts

A number of our European subsidiaries are exposed to the impact of exchange rate volatility between the U.S. dollar and the subsidiaries’ functional currencies, being either the Euro or the British Pound sterling. We entered into contracts to exchange U.S. dollars for Euros and British Pound sterling through September 2021, which we account for as cash flow hedges. The aggregate notional amount of these contracts was $418.5 million and $416.5 million at March 31, 2019 and December 31, 2018, respectively.  The purpose of these contracts is to hedge a portion of the forecasted transactions of our European subsidiaries under long-term sales contracts with certain customers. These contracts are expected to provide us with a more balanced matching of future cash receipts and expenditures by currency, thereby reducing our exposure to fluctuations in currency exchange rates.  The effective portion of the hedges, losses of $3.6 million were recorded in other comprehensive income (“OCI”) for the three months ended March 31, 2019 and gains of $8.4 million for the three months ended March 31, 2018.  We classified the carrying amount of these contracts of $1.1 million in other assets and $17.1 million in other liabilities, of which $10.0 million is recorded in noncurrent liabilities, on the Condensed Consolidated Balance Sheets at March 31, 2019 and $1.3 million in other assets and $15.3 million in other liabilities at December 31, 2018.  We recognized net losses of $1.8 million in gross margin during the three months ended March 31, 2019 and net gains of $2.3 million for the three months ended March 31, 2018.  

In addition, we enter into foreign exchange forward contracts which are not designated as hedges. These are used to provide an offset to transactional gains or losses arising from the re-measurement of non-functional monetary assets and liabilities such as accounts receivable. The change in the fair value of the derivatives is recorded in the statement of operations. There are no credit contingency features in these derivatives. During the quarters ended March 31, 2019 and 2018, we recognized net foreign exchange gains of $0.3 million and $2.0 million, respectively, in the Condensed Consolidated Statements of Operations. The net foreign exchange impact recognized from these hedges offset the translation exposure of these transactions. The carrying amount of the contracts for derivatives not designated as hedging instruments was $0.1 million classified in other assets and $0.2 million in other liabilities at March 31, 2019, and $0.3 million in other assets at December 31, 2018, in the Condensed Consolidated Balance Sheets.

 The change in fair value of our foreign currency forward exchange contracts under hedge designations recorded net of tax within accumulated other comprehensive income for the quarters ended March 31, 2019 and March 31, 2018 was as follows:

Unrealized losses of $6.5 million recorded in accumulated other comprehensive loss, net of tax of $2.5 million, as of March 31, 2019, are expected to be reclassified into earnings over the next twelve months as the hedged sales are recorded.

Commodity Swap Agreements

12

On occasion we enter into commodity swap agreements to hedge against price fluctuations of raw materials, including propylene (the principal component of acrylonitrile).  As of March 31, 2019, we had commodity swap agreements with a notional value of $ 20.1 million. The swaps mature monthly t hrough March 202 1 . The swaps are accounted for as a cash flow hedge of our forward raw material purchases. To ensure the swaps are highly effective, all of the critical terms of the swap matched the terms of the hedged items. The fair value of the commodity swap agreements was a liability of $ 4 . 6 million at March 31, 2019.

Note 8 — Income Taxes

The income tax provision for the current quarter was $20.6 million compared to $14.1 million for the quarter ended March 31, 2018. Both periods benefited from deductions associated with share based compensation payments. Our underlying estimated annual effective income tax rate is expected to remain at 24%.            

Note 9 — Fair Value Measurements

The authoritative guidance for fair value measurements establishes a hierarchy for observable and unobservable inputs used to measure fair value, into three broad levels, which are described below:

In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value.

We have no assets or liabilities that utilize Level 1 inputs. However, we have derivative instruments classified as liabilities and assets which utilize Level 2 inputs, and one liability that utilizes Level 3 inputs.

For derivative assets and liabilities that utilize Level 2 inputs, we prepare estimates of future cash flows of our derivatives, which are discounted to a net present value. The estimated cash flows and the discount factors used in the valuation model are based on observable inputs, and incorporate non-performance risk (the credit standing of the counterparty when the derivative is in a net asset position, and the credit standing of Hexcel when the derivative is in a net liability position). The fair value of these assets and liabilities was approximately $1.5 million and $22.6 million, respectively, at March 31, 2019.  In addition, the fair value of these derivative contracts, which are subject to a master netting arrangement under certain circumstances, is presented on a gross basis in the Consolidated Balance Sheet.

Below is a summary of valuation techniques for all Level 2 financial assets and liabilities:

Counterparties to the above contracts are highly rated financial institutions, none of which experienced any significant downgrades in the quarter ended March 31, 2019 that would reduce the receivable amount owed, if any, to the Company.

Liabilities classified as Level 3 — we have a liability for $3.0 million, which represents contingent consideration that was recognized in connection with the Company’s Oxford Performance Materials acquisition. This amount was estimated based on certain contractual stipulations which require payments to be made to the seller in the future based upon the achievement of certain results. We used forecasted results which were discounted using an internally derived discount rate. Future amounts payable may differ from this estimate by the difference between the actual and forecasted results. The amount of interest related to this liability accreted during the three months ended March 31, 2019 was not material.  

13

Note 10 — Revenue

Our revenue is primarily derived from the sale of inventory under long-term agreements with our customers. We have determined that individual purchase orders (“PO”), whose terms and conditions taken with a master agreement, create the ASC 606 contracts which are generally short-term in nature.  For those sales, which are not tied to a long-term agreement, we generate a PO that is subject to our standard terms and conditions. In instances where our customers acquire our goods related to government contracts, the contracts are typically subject to terms similar, or equal to, the Federal Acquisition Regulation Part 52.249-2, which contains a termination for convenience clause (“T for C”), which requires that the customer pay for the cost of both the finished and unfinished goods at the time of cancellation plus a reasonable profit.

We recognize revenue over time for those agreements that have T for C, and where the products being produced have no alternative use.  As our production cycle is typically six months or less, it is expected that goods related to the revenue recognized over time will be shipped and billed within the current year. Less than half of our agreements contain provisions which would require revenue to be recognized over time.

We disaggregate our revenue based on market for analytical purposes. The following table details our revenue by market for the three months ended March 31, 2019 and 2018:

Revenue recognized over time gives rise to contract assets, which represent revenue recognized but unbilled.  Contract assets are included in our Consolidated Balance Sheets as a component of current assets. The activity related to contract assets for the three months ended March 31, 2019 is as follows :

Accounts receivable, net includes amounts billed to customers where the right to payment is unconditional.  

Note 11 — Segment Information

The financial results for our operating segments are prepared using a management approach, which is consistent with the basis and manner in which we internally segregate financial information for the purpose of assisting in making internal operating decisions. We evaluate the performance of our operating segments based on operating income, and generally account for intersegment sales based on arm’s length prices.  Corporate and certain other expenses are not allocated to the operating segments, except to the extent that the expense can be directly attributable to the business segment.

14

Financial information for our operating segments for the three months ended March 31, 2019 and 2018 were as follows:

The addition to goodwill and intangible assets is due to the acquisition of ARC Technologies LLC, discussed in Note 13. At March 31, 2019, the balance of goodwill and intangible assets was $189.4 million and $96.8 million, respectively. No impairments have been recorded against these amounts.

15

Note 1 2 — Accumulated Other Comprehensive Loss

Comprehensive income represents net income and other gains and losses affecting stockholders’ equity that are not reflected in the Consolidated Statements of Operations. The components of accumulated other comprehensive loss as of March 31, 2019 and December 31, 2018 were as follows:

The amounts reclassified to earnings from the unrecognized net defined benefit and postretirement plan costs component of accumulated other comprehensive loss for the three months ended March 31, 2019, were $0.2 million with no material tax impact. The amounts reclassified to earnings from the change in fair value of the derivatives component of accumulated other comprehensive loss for the quarter ended March 31, 2019 were net losses of $1.8 million less taxes of $0.4 million related to foreign currency forward exchange contracts and $0.7 million less taxes of $0.2 million related to commodity swaps. We also recorded net gains of $0.4 million less taxes of $0.1 million related to interest rate swaps. 

Note 13 — Acquisitions

       During the quarter ended March 31, 2019, w e acquired all of the outstanding equity interests in ARC Technologies LLC, a leading supplier of customer RF/EMI and microwave absorbing composite materials for military, aerospace and industrial applications, for approximately $158.4 million in cash, plus a future payment of $5.4 million, that will be paid in 2019. This acquisition was accounted for as a business combination in accordance with ASC 805,  Business Combinations.  

In connection with the acquisition, the Company recognized approximately $82.8 million of goodwill, and approximately $63.0 million of intangible assets which are included in our Engineered Products segment.

Note 14 — Commitments and Contingencies

We are involved in litigation, investigations and claims arising out of the normal conduct of our business, including those relating to commercial transactions, environmental, employment and health and safety matters. While it is impossible to predict the ultimate resolution of litigation, investigations and claims asserted against us , we believe, based upon our examination of currently available information, our experience to date, and advice from legal counsel, that, after taking into account our existing insurance coverage and amounts already provided for, the currently pending legal proceedings against us will not have a material adverse impact on our consolidated results of operations, financial position or cash flows.

Environmental Matters

We have been named as a potentially responsible party (“PRP”) with respect to the below hazardous waste disposal sites that we do not own or possess, which are included on, or proposed to be included on, the Superfund National Priority List of the U.S. Environmental Protection Agency (“EPA”) or on equivalent lists of various state governments. Because the Federal Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA” or “Superfund”) allows for joint and several liability in certain circumstances, we could be responsible for all remediation costs at such sites, even if we are one of many PRPs. We believe, based on the amount and nature of our waste, and the number of other financially viable PRPs, that our liability in connection with such environmental matters will not be material.

16

L ower Passaic River Study Area

Hexcel together with approximately 48 other PRPs that comprise the Lower Passaic Cooperating Parties Group (the “CPG”), are subject to a May 2007 Administrative Order on Consent (“AOC”) with the EPA requiring the CPG to perform a Remedial Investigation/Feasibility Study of environmental conditions of a 17-mile stretch of the Passaic River in New Jersey (the “Lower Passaic River”). We were included in the CPG based on our operations at our former manufacturing site in Lodi, New Jersey.        

In March 2016, the EPA issued a Record of Decision (“ROD”) setting forth the EPA’s selected remedy for the lower eight miles of the Lower Passaic River at an expected cost ranging from $0.97 billion to $2.07 billion. This estimate does not include any costs related to a future remedy for the upper nine miles of the Lower Passaic River. In August 2017, the EPA appointed an independent third party allocation expert to make recommendations on the relative liability of approximately 120 identified non-government PRP’s, which is not expected to be completed until 2020.

In October 2016, pursuant to a settlement agreement with the EPA, Occidental Chemical Corporation (“OCC”), one of the PRPs commenced performance of the remedial design required by the ROD, reserving its right of cost contribution from all other PRPs. In June 2018, OCC filed suit against approximately 120 parties, including Hexcel, in the U.S. District Court of the District of New Jersey seeking cost recovery and contribution under CERCLA related to the Lower Passaic River. We do not know whether this litigation will impact the EPA’s allocation process or the ultimate outcome of the matter.

The accrual was $2.1 million as of March 31, 2019 and at December 31, 2018. Given the uncertainty associated with the many elements of the Superfund process for the Lower Passaic River, the amounts accrued may not be indicative of the amounts for which we will ultimately be responsible.

Omega Chemical Corporation Superfund Site, Whittier, California

We are a PRP at a former chemical waste site in Whittier, California. The PRPs at Omega have established The Omega Chemical Site PRP Organized Group, (the “OPOG”), and are currently investigating and remediating soil and groundwater at the site pursuant to a Consent Decree with the EPA. OPOG has attributed either 1.21% or 2.07% of the waste tonnage (dependent on the specific location within the Omega Chemical Site) sent to the site to Hexcel.  In addition to the Omega site specifically, the EPA is investigating the scope of regional groundwater contamination in the vicinity of the Omega site and issued an ROD; the OPOG members have been served notice by the EPA as PRPs who will be required to be involved in the remediation of the regional groundwater contamination in that vicinity as well.  As a member of OPOG, Hexcel will incur costs associated with the investigation and remediation of the Omega site and the regional groundwater remedy, although our ultimate liability, if any, in connection with this matter cannot be determined at this time. The total accrued liability relating to potential liability for both the Omega site and regional groundwater remedies was $0.3 million at March 31, 2019 and at December 31, 2018.

Summary of Environmental Reserves

Our estimate of liability as a PRP and our remaining costs associated with our responsibility to remediate the Lower Passaic River and other sites are accrued in the consolidated balance sheets. As of March 31, 2019 and December 31, 2018, our aggregate environmental related accruals were $2.6 million and $2.7 million, respectively, of which $0.7 million and $0.8 million, respectively, was included in accrued liabilities with the remainder included in non-current liabilities.  As related to certain environmental matters the accrual was estimated at the low end of a range of possible outcomes since no amount within the range is a better estimate than any other amount.  If we had accrued, for those sites where we are able to estimate our liability, at the high end of the range of possible outcomes, our accrual would have been $16 million higher at March 31, 2019.

These accruals can change significantly from period to period due to such factors as additional information on the nature or extent of contamination, the methods of remediation required, changes in the apportionment of costs among responsible parties and other actions by governmental agencies or private parties, or the impact, if any, of being named in a new matter.

Product Warranty

We provide standard assurance-type warranties for our products, which cannot be purchased separately and do not meet the criteria to be considered a performance obligation. Warranty expense for the quarter ended March 31, 2019, and accrued warranty cost, included in “accrued liabilities” in the Condensed Consolidated Balance Sheets at March 31, 2019 and December 31, 2018, were as follows:
