NOTES TO THE UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

1. Description of the Company and Basis of Presentation

Description of the Company

Celanese Corporation and its subsidiaries (collectively, the "Company") is a global technology and specialty materials company. The Company's business involves processing chemical raw materials, such as methanol, carbon monoxide and ethylene, and natural products, including wood pulp, into value-added chemicals, thermoplastic polymers and other chemical-based products.

Definitions

In this Quarterly Report on Form 10-Q ("Quarterly Report"), the term "Celanese" refers to Celanese Corporation, a Delaware corporation, and not its subsidiaries. The term "Celanese US" refers to the Company's subsidiary, Celanese US Holdings LLC, a Delaware limited liability company, and not its subsidiaries.

Basis of Presentation

The unaudited interim consolidated financial statements for the three months ended March 31, 2018 and 2017 contained in this Quarterly Report were prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP") for all periods presented and include the accounts of the Company, its majority owned subsidiaries over which the Company exercises control and, when applicable, variable interest entities in which the Company is the primary beneficiary. The unaudited interim consolidated financial statements and other financial information included in this Quarterly Report, unless otherwise specified, have been presented to separately show the effects of discontinued operations.

In the opinion of management, the accompanying unaudited consolidated balance sheets and related unaudited interim consolidated statements of operations, comprehensive income (loss), cash flows and equity include all adjustments, consisting only of normal recurring items necessary for their fair presentation in conformity with US GAAP. Certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted in accordance with rules and regulations of the Securities and Exchange Commission ("SEC"). These unaudited interim consolidated financial statements should be read in conjunction with the Company's consolidated financial statements as of and for the year ended December 31, 2017, filed on February 9, 2018 with the SEC as part of the Company's Annual Report on Form 10-K.

Operating results for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the entire year.

In the ordinary course of business, the Company enters into contracts and agreements relative to a number of topics, including acquisitions, dispositions, joint ventures, supply agreements, product sales and other arrangements. The Company endeavors to describe those contracts or agreements that are material to its business, results of operations or financial position. The Company may also describe some arrangements that are not material but in which the Company believes investors may have an interest or which may have been included in a Form 8-K filing. Investors should not assume the Company has described all contracts and agreements relative to the Company's business in this Quarterly Report.

For those consolidated ventures in which the Company owns or is exposed to less than 100% of the economics, the outside stockholders' interests are shown as noncontrolling interests.

During the three months ended March 31, 2018, the Company settled its dispute concerning the exercise of an option right by a partner in two of the Company's InfraServ equity affiliate investments. As a result of the settlement, the Company's ownership in InfraServ GmbH & Co. Gendorf KG and InfraServ GmbH & Co. Knapsack KG was reduced from 39% and 27%, to 30% and 22%, respectively.

The Company has reclassified certain prior period amounts due to (1) the adoption of ASU 2017-07 (defined below in Note 2) and (2) to conform to the presentation of the Company's current reportable segments (Note 19).

Table of Contents

Estimates and Assumptions

The preparation of unaudited interim consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements and the reported amounts of Net sales, expenses and allocated charges during the reporting period. Significant estimates pertain to impairments of goodwill, intangible assets and other long-lived assets, purchase price allocations, restructuring costs and other (charges) gains, net, income taxes, pension and other postretirement benefits, asset retirement obligations, environmental liabilities and loss contingencies, among others. Actual results could differ from those estimates.

2. Recent Accounting Pronouncements

The following table provides a brief description of recent Accounting Standard Updates ("ASU") issued by the Financial Accounting Standards Board ("FASB"):



Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters

In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.	The new guidance allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users.	January 1, 2019. Early adoption is permitted.	The Company is currently evaluating the impact of adoption on its financial statements and related disclosures.

In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities.	The new guidance improves the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results.	January 1, 2019. Early adoption is permitted.	The Company adopted the new guidance effective January 1, 2018, as part of the FASB's simplification initiative. The adoption of the new guidance did not have a material impact to the Company.

In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.	The new guidance clarifies the presentation and classification of the components of net periodic benefit costs in the consolidated statement of operations.	January 1, 2018.	The Company adopted the new guidance effective January 1, 2018, using the retrospective transition method, as part of the FASB's simplification initiative. See Adoption of ASU 2017-07 section below for additional information.

In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory.	The new guidance requires the income tax consequences of an intra-entity transfer of assets other than inventory to be recognized when the transfer occurs rather than deferring until an outside sale has occurred.	January 1, 2018.	The Company adopted the new guidance effective January 1, 2018, as part of the FASB's simplification initiative. The adoption of the new guidance did not have a material impact to the Company.

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments.	The new guidance clarifies the presentation and classification of certain cash receipts and cash payments in the statement of cash flows.	January 1, 2018.	The Company adopted the new guidance effective January 1, 2018, as part of the FASB's simplification initiative. The adoption of the new guidance did not have a material impact to the Company.

In February 2016, the FASB issued ASU 2016-02, Leases.	The new guidance supersedes the lease guidance under FASB Accounting Standards Codification ("ASC") Topic 840, Leases, resulting in the creation of FASB ASC Topic 842, Leases. The guidance requires a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for both finance and operating leases.	January 1, 2019. Early adoption is permitted.	The Company is currently evaluating its population of leases, and is continuing to assess all potential impacts of the standard, but currently believes the most significant impact relates to its accounting for manufacturing and logistics equipment, and real estate operating leases. The Company anticipates recognition of additional assets and corresponding liabilities related to leases upon adoption, but has not yet quantified these at this time. The Company plans to adopt the standard effective January 1, 2019, but has not yet selected a transition method.

Table of Contents



Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities.	The new guidance updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments.	January 1, 2018.	The Company adopted the new guidance effective January 1, 2018, using the modified retrospective approach, as part of the FASB's simplification initiative. The new guidance resulted in a cumulative-effect adjustment of less than $1 million to January 1, 2018 Retained earnings.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. Since that date, the FASB has issued additional ASUs clarifying certain aspects of ASU 2014-09.	The new guidance requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The new guidance provides alternative methods of adoption. Subsequent guidance issued after May 2014 did not change the core principle of ASU 2014-09.	January 1, 2018.	The Company adopted the new guidance effective January 1, 2018, using the modified retrospective approach, as part of the FASB's simplification initiative. The adoption of the new guidance resulted in less than $1 million impact to the consolidated financial statements and related disclosures (See Note 20).

Adoption of ASU 2017-07

ASU 2017-07 requires an entity to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the statement of operations separately from the service cost component and outside a subtotal of Operating profit (loss). The new guidance represents a change in accounting principle. The Company adopted ASU 2017-07 on January 1, 2018 using the retrospective transition method. The adoption of this accounting standard resulted in a change in certain previously reported amounts, as follows:



	Three Months Ended March 31, 2017
	As previously reported		Adoption of ASU 2017-07		As Adjusted
	(In $ millions)
Cost of sales	(1,119	)	(2	)	(1,121	)
Selling, general and administrative expenses	(83	)	(20	)	(103	)
Operating profit (loss)	192		(22	)	170
Non-operating pension and other postretirement employee benefit (expense) income	—		22		22

The adoption of this accounting standard had no impact on the previously reported Earnings (loss) from continuing operations or Net earnings (loss) for this period.

3. Acquisitions, Dispositions and Plant Closures

Acquisitions


•	Omni Plastics

On February 1, 2018, using cash on hand and borrowings under the Company's senior unsecured revolving credit facility, the Company acquired 100% of the ownership interests of Omni Plastics, L.L.C. and its subsidiaries ("Omni Plastics"). Omni Plastics specializes in custom compounding of various engineered thermoplastic materials. The acquisition further strengthens the Company's global asset base by adding compounding capacity in the Americas. The acquisition was accounted for as a business combination and the acquired operations are included in the Engineered Materials segment.

Table of Contents

Pro forma financial information since the respective acquisition date has not been provided as the acquisition did not have a material impact on the Company's financial information. The Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. The excess of the purchase price over the aggregate fair values was recorded as goodwill. The Company calculated the fair value of the assets acquired using the income, market or cost approach (or a combination thereof). Fair values were determined based on Level 3 inputs including estimated future cash flows, discount rates, royalty rates, growth rates, sales projections, retention rates and terminal values, all of which require significant management judgment and are susceptible to change. The purchase price allocation is based upon preliminary information and is subject to change if additional information about the facts and circumstances that existed at the acquisition date becomes available. The final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill. However, any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations.

The preliminary purchase price allocation for the Omni Plastics acquisition is as follows:



	As of February 1, 2018
	(In $ millions)
Cash and cash equivalents	2
Trade receivables - third party and affiliates	12
Inventories	13
Property, plant and equipment, net	19
Intangible assets (Note 7)	35
Goodwill⁽¹⁾(Note 7)	84
Other assets	1
Total fair value of assets acquired	166

Trade payables - third party and affiliates	(8	)
Total debt	(12	)
Total fair value of liabilities assumed	(20	)
Net assets acquired	146

______________________________


⁽¹⁾	Goodwill consists of expected revenue and operating synergies resulting from the acquisition, all of which is deductible for income tax purposes.

The amount of pro forma Net earnings (loss) of Omni Plastics included in the Company's unaudited interim consolidated statement of operations was less than 1% (unaudited) of its consolidated Net earnings (loss) had the acquisition occurred as of the beginning of 2018. The amount of Omni Plastics' Net earnings (loss) consolidated by the Company since the acquisition date was not material.


•	Acetate Tow Joint Venture

In June 2017, Celanese, through various subsidiaries, entered into an agreement with affiliates of The Blackstone Group L.P. (the "Blackstone Entities") to form a joint venture which would combine substantially all of the operations of the Company's cellulose derivatives business and the operations of the Rhodia Acetow cellulose acetate business formerly operated by Solvay S.A. and acquired by the Blackstone Entities in June 2017. The parties were subsequently unable to reach an agreement with the European Commission on acceptable conditions to allow the proposed joint venture to proceed. The demands by the European Commission eliminated the advantages at the heart of the transaction. As a result, on March 19, 2018, the Company and the Blackstone Entities abandoned their agreement to form the proposed joint venture.

•	Nilit Plastics

In May 2017, using cash on hand and borrowings under the Company's senior unsecured revolving credit facility, the Company acquired the nylon compounding division of Nilit Group ("Nilit"), an independent producer of high performance nylon resins, fibers and compounds. Celanese acquired the nylon compounding product portfolio, customer agreements and manufacturing, technology and commercial facilities. The acquisition of Nilit increases the Company's global engineered materials product platforms, extends the operational model, technical and industry solutions capabilities and expands project pipelines. The acquisition was accounted for as a business combination and the acquired operations are included in the Engineered Materials segment. The purchase price allocation was based on preliminary information and is subject to change if additional information about the facts and circumstances that existed at the acquisition date becomes available. The final fair value of the net assets acquired may result in adjustments to the assets and liabilities, including goodwill. Since the acquisition date, the Company made certain adjustments to its purchase price allocation to adjust taxes and working capital, which resulted in a $2 million reduction to goodwill. Any subsequent measurement period adjustments are not expected to have a material impact on the Company's results of operations.

4. Ventures and Variable Interest Entities

Consolidated Variable Interest Entities

The Company has a joint venture, Fairway Methanol LLC ("Fairway"), with Mitsui & Co., Ltd., of Tokyo, Japan ("Mitsui"), in which the Company owns 50% of Fairway, for the production of methanol at the Company's integrated chemical plant in Clear Lake, Texas. The methanol unit utilizes natural gas in the US Gulf Coast region as a feedstock and benefits from the existing infrastructure at the Company's Clear Lake facility. Both Mitsui and the Company supply their own natural gas to Fairway in exchange for methanol tolling under a cost-plus off-take arrangement.

The Company determined that Fairway is a variable interest entity ("VIE") in which the Company is the primary beneficiary. Under the terms of the joint venture agreements, the Company provides site services and day-to-day operations for the methanol facility. In addition, the joint venture agreements provide that the Company indemnifies Mitsui for environmental obligations that exceed a specified threshold, as well as an equity option between the partners. Accordingly, the Company consolidates the venture and records a noncontrolling interest for the share of the venture owned by Mitsui. Fairway is included in the Company's Acetyl Intermediates segment.

The carrying amount of the assets and liabilities associated with Fairway included in the unaudited consolidated balance sheets are as follows:

Nonconsolidated Variable Interest Entities

The Company holds variable interests in entities that supply certain raw materials and services to the Company. The variable interests primarily relate to cost-plus contractual arrangements with the suppliers and recovery of capital expenditures for certain plant assets plus a rate of return on such assets. Liabilities for such supplier recoveries of capital expenditures have been recorded as capital lease obligations. The entities are not consolidated because the Company is not the primary beneficiary of the entities as it does not have the power to direct the activities of the entities that most significantly impact the entities' economic performance. The Company's maximum exposure to loss as a result of its involvement with these VIEs as of March 31, 2018, relates primarily to the recovery of capital expenditures for certain property, plant and equipment.

The carrying amount of the assets and liabilities associated with the obligations to nonconsolidated VIEs, as well as the maximum exposure to loss relating to these nonconsolidated VIEs are as follows:



	As of March 31, 2018	As of December 31, 2017

Long-term debt	74	76
Total liabilities	120	119

The difference between the total liabilities associated with obligations to nonconsolidated VIEs and the maximum exposure to loss primarily represents take-or-pay obligations for services included in the Company's unconditional purchase obligations (Note 18).

12. Environmental

The Company is subject to environmental laws and regulations worldwide that impose limitations on the discharge of pollutants into the air and water, establish standards for the treatment, storage and disposal of solid and hazardous wastes, and impose record keeping and notification requirements. Failure to timely comply with these laws and regulations may expose the Company to penalties. The Company believes that it is in substantial compliance with all applicable environmental laws and regulations and engages in an ongoing process of updating its controls to mitigate compliance risks. The Company is also subject to retained environmental obligations specified in various contractual agreements arising from the divestiture of certain businesses by the Company or one of its predecessor companies.

Table of Contents

Remediation

Due to its industrial history and through retained contractual and legal obligations, the Company has the obligation to remediate specific areas on its own sites as well as on divested, demerger, orphan or US Superfund sites (as defined below). In addition, as part of the demerger agreement between the Company and Hoechst AG ("Hoechst"), a specified portion of the responsibility for environmental liabilities from a number of Hoechst divestitures was transferred to the Company (Note 18). Certain of these sites, at which the Company maintains continuing involvement, were and continue to be designated as discontinued operations when closed. The Company provides for such obligations when the event of loss is probable and reasonably estimable. The Company believes that environmental remediation costs will not have a material adverse effect on the financial position of the Company, but may have a material adverse effect on the results of operations or cash flows in any given period.

US Superfund Sites

In the US, the Company may be subject to substantial claims brought by US federal or state regulatory agencies or private individuals pursuant to statutory authority or common law. In particular, the Company has a potential liability under the US Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, and related state laws (collectively referred to as "Superfund") for investigation and cleanup costs at certain sites. At most of these sites, numerous companies, including the Company, or one of its predecessor companies, have been notified that the US Environmental Protection Agency ("EPA"), state governing bodies or private individuals consider such companies to be potentially responsible parties ("PRP") under Superfund or related laws. The proceedings relating to these sites are in various stages. The cleanup process has not been completed at most sites, and the status of the insurance coverage for some of these proceedings is uncertain. Consequently, the Company cannot accurately determine its ultimate liability for investigation or cleanup costs at these sites.

As events progress at each site for which it has been named a PRP, the Company accrues, as appropriate, a liability for site cleanup. Such liabilities include all costs that are probable and can be reasonably estimated. In establishing these liabilities, the Company considers the contaminants of concern, the potential impact thereof, the relationship of the contaminants of concern to its current and historic operations, its shipment of waste to a site, its percentage of total waste shipped to the site, the types of wastes involved, the conclusions of any studies, the magnitude of any remedial actions that may be necessary and the number and viability of other PRPs. Often the Company joins with other PRPs to sign joint defense agreements that settle, among PRPs, each party's percentage allocation of costs at the site. Although the ultimate liability may differ from the estimate, the Company routinely reviews the liabilities and revises the estimate, as appropriate, based on the most current information available.

One such site is the Diamond Alkali Superfund Site, which is comprised of a number of sub-sites, including the Lower Passaic River Study Area, which is the lower 17-mile stretch of the Passaic River ("Lower Passaic River Site"), and the Newark Bay Area. The Company and 70 other companies are parties to a May 2007 Administrative Order on Consent with the EPA to perform a Remedial Investigation/Feasibility Study ("RI/FS") at the Lower Passaic River Site in order to identify the levels of contaminants and potential cleanup actions, including the potential migration of contaminants between the Lower Passaic River Site and the Newark Bay Area. Work on the RI/FS is ongoing, with a goal to complete it in 2018.

In March 2016, the EPA issued its final Record of Decision concerning the remediation of the lower 8.3 miles of the Lower Passaic River Site ("Lower 8.3 Miles"). Pursuant to the EPA's Record of Decision, the Lower 8.3 Miles must be dredged bank to bank and an engineered cap must be installed at an EPA estimated cost of approximately $1.4 billion. The Company owned and/or operated facilities in the vicinity of the Lower 8.3 Miles, but has found no evidence that it contributed any of the contaminants of concern to the Passaic River. The Company is vigorously defending this matter and currently believes that its ultimate allocable share of the cleanup costs with respect to the Lower Passaic River Site, estimated at less than 1%, will not be material to the Company's results of operations, cash flows or financial position.

15. Income Taxes



	Three Months Ended March 31,
	2018	2017
	(In percentages)
Effective income tax rate	15	23

The lower effective income tax rate for the three months ended March 31, 2018 compared to the same period in 2017 is primarily due to the corporate tax rate reduction in the US from enacted tax legislation commonly referred to as the Tax Cuts and Jobs Act ("TCJA") and decreases in losses in jurisdictions not providing tax benefit.

In December 2017, the TCJA was enacted and is effective January 1, 2018. ASC 740, Accounting for Income Taxes, requires companies to recognize the effects of tax law changes in the period of enactment. This overhaul of the US tax law made a number of substantial changes, including the reduction of the corporate tax rate from 35% to 21%, establishing a dividends received deduction for dividends paid by foreign subsidiaries to the US, elimination or limitation of certain deductions (interest, domestic production activities and executive compensation), imposing a mandatory tax on previously unrepatriated earnings

Table of Contents

accumulated offshore since 1986 and establishing global minimum income tax and base erosion tax provisions related to offshore activities and affiliated party payments.

Due to the timing of the new tax law and the substantial changes it brings, the SEC issued Staff Accounting Bulletin No. 118 ("SAB 118"), which provides registrants a measurement period to report the impact of the new US tax law. During the measurement period, provisional amounts for the effects of the law are recorded to the extent a reasonable estimate can be made. To the extent that all information necessary is not available, prepared or analyzed, companies may recognize provisional estimated amounts for a period of up to one year following enactment of the TCJA.

For year-end 2017, the Company recorded provisional amounts for impacts of the new tax law including: the deemed repatriation tax on post 1986 accumulated earnings and profits, the deferred tax rate change effect of the new law, gross foreign tax credit carryforwards and related valuation allowances to offset foreign tax credit carryforwards. Certain items or estimates that result in impacts of the TCJA being provisional include: detailed foreign earnings calculations for 2017 and 2018, projected foreign cash balances for certain foreign subsidiaries and finalized computations of foreign tax credit availability. Finally, the Company considers it likely that further technical guidance regarding certain components of the new provisions included in the TCJA, as well as clarity regarding state income tax conformity to current federal tax code, may be issued. During the three months ended March 31, 2018, the Company recorded increases to provisional amounts for valuation allowances on foreign tax credits of $24 million. The changes in provisional amounts are primarily due to refined estimates of foreign source income and expense apportionment during the credit carryforward period. The Company will continue to refine provisional amounts for the impacts of the TCJA as more refined information and further guidance become available.

During the three months ended March 31, 2018, the Company's uncertain tax positions decreased $5 million, primarily due to favorable technical clarifications in Germany, partially offset by an increase in US positions and foreign currency exchange fluctuations.

In connection with the Company's US federal income tax audit for 2009 and 2010, the Company has received $192 million of proposed pre-tax adjustments related to various intercompany charges. In January 2018, the Company received proposed pre-tax adjustments for its 2011 and 2012 audit cycle in the amount of $198 million. In the event the Company is wholly unsuccessful in its defense and absent expected offsetting adjustments from foreign tax authorities, the proposed adjustments would result in the consumption of approximately $136 million of prior foreign tax credit carryforwards, which are substantially offset with a valuation allowance due to uncertain recoverability. The Company believes these proposed adjustments to be without merit and is vigorously defending its position.

16. Derivative Financial Instruments

Net Investment Hedges

The Company uses derivative instruments, such as foreign currency forwards, and non-derivative financial instruments, such as foreign currency denominated debt, that may give rise to foreign currency transaction gains or losses to hedge the foreign currency exposure of net investments in foreign operations. Accordingly, the effective portion of gains and losses from remeasurement of derivative and non-derivative financial instruments is included in foreign currency translation within Accumulated other comprehensive income (loss), net in the unaudited consolidated balance sheets. Gains and losses are reclassified to earnings in the period the hedged investment is sold or liquidated.

The total notional amount of foreign currency denominated debt designated as a net investment hedge of net investments in foreign operations are as follows:

17. Fair Value Measurements

The Company's financial assets and liabilities are measured at fair value on a recurring basis as follows:

Derivatives. Derivative financial instruments, including commodity swaps and foreign currency forwards and swaps, are valued in the market using discounted cash flow techniques. These techniques incorporate Level 1 and Level 2 fair value measurement inputs such as spot rates and foreign currency exchange rates. These market inputs are utilized in the discounted cash flow calculation considering the instrument's term, notional amount, discount rate and credit risk. Significant inputs to the derivative valuation for commodity swaps and foreign currency forwards and swaps are observable in the active markets and are classified as Level 2 in the fair value measurement hierarchy.

	(In $ millions)
As of March 31, 2018

In general, the cost investments included in the table above are not publicly traded and their fair values are not readily determinable. As such, the Company believes the carrying values approximate fair value. Insurance contracts in nonqualified trusts consist of long-term fixed income securities, which are valued using independent vendor pricing models with observable inputs in the active market and therefore represent a Level 2 fair value measurement. The fair value of long-term debt is based on valuations from third-party banks and market quotations and is classified as Level 2 in the fair value measurement hierarchy. The fair value of obligations under capital leases, which are included in long-term debt, is based on lease payments and discount rates, which are not observable in the market and therefore represents a Level 3 fair value measurement.

Table of Contents

As of March 31, 2018, and December 31, 2017, the fair values of cash and cash equivalents, receivables, trade payables, short-term borrowings and the current installments of long-term debt approximate carrying values due to the short-term nature of these instruments. These items have been excluded from the table with the exception of the current installments of long-term debt.

18. Commitments and Contingencies

Commitments

Guarantees

The Company has agreed to guarantee or indemnify third parties for environmental and other liabilities pursuant to a variety of agreements, including asset and business divestiture agreements, leases, settlement agreements and various agreements with affiliated companies. Although many of these obligations contain monetary and/or time limitations, others do not provide such limitations. The Company has accrued for all probable and reasonably estimable losses associated with all known matters or claims. These known obligations include the following:


•	Demerger Obligations

In connection with the Hoechst demerger, the Company agreed to indemnify Hoechst, and its legal successors, for various liabilities under the demerger agreement, including for environmental liabilities associated with contamination arising either from environmental damage in general ("Category A") or under 19 divestiture agreements entered into by Hoechst prior to the demerger ("Category B") (Note 12).

The Company's obligation to indemnify Hoechst, and its legal successors, is capped under Category B at €250 million. If and to the extent the environmental damage should exceed €750 million in aggregate, the Company's obligation to indemnify Hoechst and its legal successors applies, but is then limited to 33.33% of the remediation cost without further limitations. Cumulative payments under the divestiture agreements as of March 31, 2018, are $82 million. Most of the divestiture agreements have become time barred and/or any notified environmental damage claims have been partially settled.

The Company has also undertaken in the demerger agreement to indemnify Hoechst and its legal successors for (i) 33.33% of any and all Category A liabilities that result from Hoechst being held as the responsible party pursuant to public law or current or future environmental law or by third parties pursuant to private or public law related to contamination and (ii) liabilities that Hoechst is required to discharge, including tax liabilities, which are associated with businesses that were included in the demerger but were not demerged due to legal restrictions on the transfers of such items. These indemnities do not provide for any monetary or time limitations. The Company has not been requested by Hoechst to make any payments in connection with this indemnification. Accordingly, the Company has not made any payments to Hoechst and its legal successors.

Based on the Company's evaluation of currently available information, including the lack of requests for indemnification, the Company cannot estimate the Possible Loss for the remaining demerger obligations, if any, in excess of amounts accrued.


•	Divestiture Obligations

The Company and its predecessor companies agreed to indemnify third-party purchasers of former businesses and assets for various pre-closing conditions, as well as for breaches of representations, warranties and covenants. Such liabilities also include environmental liability, product liability, antitrust and other liabilities. These indemnifications and guarantees represent standard contractual terms associated with typical divestiture agreements and, other than environmental liabilities, the Company does not believe that they expose the Company to significant risk (Note 12).

The Company has divested numerous businesses, investments and facilities through agreements containing indemnifications or guarantees to the purchasers. Many of the obligations contain monetary and/or time limitations, which extend through 2037. The aggregate amount of outstanding indemnifications and guarantees provided for under these agreements is $123 million as of March 31, 2018. Other agreements do not provide for any monetary or time limitations.

Based on the Company's evaluation of currently available information, including the number of requests for indemnification or other payment received by the Company, the Company cannot estimate the Possible Loss for the remaining divestiture obligations, if any, in excess of amounts accrued.

Table of Contents

Purchase Obligations

In the normal course of business, the Company enters into various purchase commitments for goods and services. The Company maintains a number of "take-or-pay" contracts for purchases of raw materials, utilities and other services. Certain of the contracts contain a contract termination buy-out provision that allows for the Company to exit the contracts for amounts less than the remaining take-or-pay obligations. Additionally, the Company has other outstanding commitments representing maintenance and service agreements, energy and utility agreements, consulting contracts and software agreements. As of March 31, 2018, the Company had unconditional purchase obligations of $1.7 billion, which extend through 2036.

Contingencies

The Company is involved in legal and regulatory proceedings, lawsuits, claims and investigations incidental to the normal conduct of business, relating to such matters as product liability, land disputes, insurance coverage disputes, commercial contracts, employment, antitrust or competition compliance, intellectual property, personal injury and other actions in tort, workers' compensation, chemical exposure, asbestos exposure, taxes, trade compliance, acquisitions and divestitures, claims of legacy stockholders, past waste disposal practices and release of chemicals into the environment. The Company is actively defending those matters where the Company is named as a defendant and, based on the current facts, does not believe the outcomes from these matters will be material to the Company's results of operations, cash flows or financial position.

European Commission

In May 2017, the Company learned that the European Commission opened a competition law investigation involving certain subsidiaries of the Company with respect to certain ethylene purchases. The Company is cooperating with the European Commission. Because the investigation is on-going and the many uncertainties and variables involved, the Company is unable at this time to determine the outcome of this investigation and whether, and in what amount, any potential fines would be assessed.

19. Segment Information

Effective January 1, 2018, the Company reorganized its operating and reportable segments to align with recent structural and management reporting changes. The change reflects the movement of its food ingredients business from the Consumer Specialties reportable segment into the Engineered Materials reportable segment. The former Consumer Specialties reportable segment was renamed the Acetate Tow segment, and the former Advanced Engineered Materials reportable segment was renamed the Engineered Materials segment. This reorganization better reflects how the Company manages its food ingredients' related products commercially. Engineered Materials and food ingredients are both project-based models which focus on delivering customized solutions and are led by the same senior management team.

20. Revenue Recognition

Accounting Policies

Revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied. The majority of the Company's contracts have a single performance obligation to transfer products. Accordingly, the Company recognizes revenue when title and risk of loss have been transferred to the customer, generally at the time of shipment of products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products and is generally based upon a negotiated, formula, list or fixed price. The Company sells its products both directly to customers and through distributors generally under agreements with payment terms typically less than 90 days.

The Company has elected to account for shipping and handling as activities to fulfill the promise to transfer the good. As such, shipping and handling fees billed to customers in a sales transaction are recorded in Net sales and shipping and handling costs incurred are recorded in Cost of sales. The Company has elected to exclude from Net sales any value add, sales and other taxes which it collects concurrent with revenue-producing activities. These accounting policy elections are consistent with the manner in which the Company historically recorded shipping and handling fees and taxes.

The adoption of ASU 2014-09 resulted in an immaterial impact to the individual financial statement line items of the Company's unaudited interim consolidated statement of operations during the three months ended March 31, 2017.

Contract Estimates

The nature of certain of the Company's contracts gives rise to variable consideration, which may be constrained, including retrospective volume-based rebates to certain customers. The Company issues retrospective volume-based rebates to customers when they purchase a certain volume level, and the rebates are applied retroactively to prior purchases. The Company also issues prospective volume-based rebates to customers when they purchase a certain volume level, and the rebates are applied to future purchases. Prospective volume-based rebates represent a material right within the contract and therefore are considered to be separate performance obligations. For both retrospective and prospective volume-based rebates, the Company estimates the level of volumes based on anticipated purchases at the beginning of the period and records a rebate accrual for each purchase toward the requisite rebate volume. These estimated rebates are included in the transaction price of the Company's contracts with customers as a reduction to Net sales and are included in Current Other liabilities in the Consolidated Balance Sheets (Note 8). This methodology is consistent with the manner in which the Company historically estimated and recorded volume-based rebates.

The majority of the Company's revenue is derived from contracts (i) with an original expected length of one year or less and (ii) contracts for which it recognizes revenue at the amount in which it has the right to invoice as product is delivered. The Company has elected the practical expedient not to disclose the value of remaining performance obligations associated with these types of contracts. However, the Company has certain contracts that represent take-or-pay revenue arrangements in which the Company's performance obligations extend over multiple years. As of March 31, 2018, the Company had $910 million of remaining performance obligations related to take-or-pay contracts. The Company expects to recognize approximately $198 million of its remaining performance obligations as Net sales in 2018, $220 million in 2019, an additional $180 million in 2020 and the balance thereafter.

The Company has certain contracts which contain performance obligations which are immaterial in the context of the contract with the customer. The Company has elected the practical expedient not to assess whether these promised goods or services are performance obligations.

Contract Balances

Contract liabilities primarily relate to advances or deposits received from the Company's customers before revenue is recognized. These amounts are recorded as deferred revenue and are included in Noncurrent Other liabilities in the Consolidated Balance Sheets (Note 9).

The Company does not have any material contract assets as of March 31, 2018.

Disaggregated Revenue

In general, the Company's business segmentation is aligned according to the nature and economic characteristics of its products and customer relationships and provides meaningful disaggregation of each business segment's results of operations.

Table of Contents

The Company manages its Engineered Materials business segment through its project management pipeline, which is comprised of a broad range of projects which are solutions-based and are tailored to each customers' unique needs. Projects are identified and selected based on success rate and may involve a number of different polymers per project for use in multiple end-use applications. Therefore, the Company is agnostic toward products and end-use markets for the Engineered Materials business segment.

Within the Acetate Tow business segment, the Company's primary product is acetate tow, which is managed through contracts with a few major tobacco companies and accounts for a significant amount of filters used in cigarette production worldwide.

The Company manages its Industrial Specialties and Acetyl Intermediates business segments by leveraging its ability to sell chemicals upstream to end-use markets or downstream to its emulsion polymers business (within its Industrial Specialties segment). Decisions to sell upstream and geographically or downstream and along the acetyl chain are based on market demand, trade flows and maximizing the value of its chemicals. Therefore, the Company's strategic focus is on executing within this integrated chain model and less on driving product-specific revenue.

Further disaggregation of Net sales by business segment and geographic destination is as follows:

22. Consolidating Guarantor Financial Information

The Senior Notes were issued by Celanese US ("Issuer") and are guaranteed by Celanese Corporation ("Parent Guarantor") and the Subsidiary Guarantors (Note 10). The Issuer and Subsidiary Guarantors are 100% owned subsidiaries of the Parent Guarantor. The Parent Guarantor and Subsidiary Guarantors have guaranteed the Notes fully and unconditionally and jointly and severally.

For cash management purposes, the Company transfers cash between the Parent Guarantor, Issuer, Subsidiary Guarantors and non-guarantors through intercompany financing arrangements, contributions or declaration of dividends between the respective parent and its subsidiaries. The transfer of cash under these activities facilitates the ability of the recipient to make specified third-party payments for principal and interest on the Company's outstanding debt, Common Stock dividends and Common Stock repurchases. The unaudited interim consolidating statements of cash flows for the three months ended March 31, 2018 and 2017 present such intercompany financing activities, contributions and dividends consistent with how such activity would be presented in a stand-alone statement of cash flows.

The Company has not presented separate financial information and other disclosures for each of its Subsidiary Guarantors because it believes such financial information and other disclosures would not provide investors with any additional information that would be material in evaluating the sufficiency of the guarantees.

The unaudited interim consolidating financial statements for the Parent Guarantor, the Issuer, the Subsidiary Guarantors and the non-guarantors are as follows:

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

In this Quarterly Report on Form 10-Q ("Quarterly Report"), the term "Celanese" refers to Celanese Corporation, a Delaware corporation, and not its subsidiaries. The terms the "Company," "we," "our" and "us," refer to Celanese and its subsidiaries on a consolidated basis. The term "Celanese US" refers to the Company's subsidiary, Celanese US Holdings LLC, a Delaware limited liability company, and not its subsidiaries.

The following discussion should be read in conjunction with the Celanese Corporation and Subsidiaries consolidated financial statements as of and for the year ended December 31, 2017 filed on February 9, 2018 with the Securities and Exchange Commission ("SEC") as part of the Company's Annual Reporting on Form 10-K ("2017 Form 10-K") and the unaudited interim consolidated financial statements and notes to the unaudited interim consolidated financial statements, which are prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP").

Investors are cautioned that the forward-looking statements contained in this section and other parts of this Quarterly Report involve both risk and uncertainty. Several important factors could cause actual results to differ materially from those anticipated by these statements. Many of these statements are macroeconomic in nature and are, therefore, beyond the control of management. See "Forward-Looking Statements" below and at the beginning of our 2017 Form 10-K.

Forward-Looking Statements

Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") and other parts of this Quarterly Report contain certain forward-looking statements and information relating to us that are based on the beliefs of our management as well as assumptions made by, and information currently available to, us. Generally, words such as "believe," "expect," "intend," "estimate," "anticipate," "project," "plan," "may," "can," "could," "might," and "will," and similar expressions, as they relate to us are intended to identify forward-looking statements. These statements reflect our current views and beliefs with respect to future events at the time that the statements are made, are not historical facts or guarantees of future performance and involve risks and uncertainties that are difficult to predict and many of which are outside of our control. Further, certain forward-looking statements are based upon assumptions as to future events that may not prove to be accurate. All forward-looking statements made in this Quarterly Report are made as of the date hereof, and the risk that actual results will differ materially from expectations expressed in this Quarterly Report will increase with the passage of time. We undertake no obligation, and disclaim any duty, to publicly update or revise any forward-looking statements, whether as a result of new information, future events, changes in our expectations or otherwise.

Risk Factors

See Part I - Item 1A. Risk Factors of our 2017 Form 10-K and subsequent periodic filings we make with the SEC for a description of certain risk factors that you should consider which could significantly affect our financial results. In addition, the following factors could cause our actual results to differ materially from those results, performance or achievements that may be expressed or implied by such forward-looking statements. These factors include, among other things:


•	changes in general economic, business, political and regulatory conditions in the countries or regions in which we operate;


•	the length and depth of product and industry business cycles particularly in the automotive, electrical, textiles, electronics and construction industries;


•	changes in the price and availability of raw materials, particularly changes in the demand for, supply of, and market prices of ethylene, methanol, natural gas, wood pulp and fuel oil and the prices for electricity and other energy sources;


•	the ability to pass increases in raw material prices on to customers or otherwise improve margins through price increases;


•	the ability to maintain plant utilization rates and to implement planned capacity additions, expansions and maintenance;


•	the ability to reduce or maintain current levels of production costs and to improve productivity by implementing technological improvements to existing plants;


•	increased price competition and the introduction of competing products by other companies;


•	the ability to identify desirable potential acquisition targets and to consummate acquisition or investment transactions, including obtaining regulatory approvals, consistent with our strategy;

Table of Contents


•	market acceptance of our technology;


•	the ability to obtain governmental approvals and to construct facilities on terms and schedules acceptable to us;


•	changes in tariffs, tax rates or legislation throughout the world including, but not limited to, adjustments, changes in estimates or interpretations that may impact recorded or future tax impacts associated with tax legislation in the US, commonly referred to as the Tax Cuts and Jobs Act (the "TCJA") enacted in December 2017;


•	changes in the degree of intellectual property and other legal protection afforded to our products or technologies, or the theft of such intellectual property;

•

compliance and other costs and potential disruption or interruption of production or operations due to accidents, interruptions in sources of raw materials, cyber security incidents, terrorism or political unrest, or other unforeseen events or delays in construction or operation of facilities, including as a result of geopolitical conditions, the occurrence of acts of war or terrorist incidents or as a result of weather or natural disasters;


•	potential liability for remedial actions and increased costs under existing or future environmental regulations, including those relating to climate change;


•	potential liability resulting from pending or future claims or litigation, including investigations or enforcement actions, or from changes in the laws, regulations or policies of governments or other governmental activities, in the countries in which we operate;


•	changes in currency exchange rates and interest rates;


•	our level of indebtedness, which could diminish our ability to raise additional capital to fund operations or limit our ability to react to changes in the economy or the chemicals industry; and


•	various other factors, both referenced and not referenced in this Quarterly Report.

Many of these factors are macroeconomic in nature and are, therefore, beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, our actual results, performance or achievements may vary materially from those described in this Quarterly Report as anticipated, believed, estimated, expected, intended, planned or projected. We neither intend nor assume any obligation to update these forward-looking statements, which speak only as of their dates.

Consolidated Results

Three Months Ended March 31, 2018 Compared to Three Months Ended March 31, 2017

Net sales increased $380 million, or 25.8%, for the three months ended March 31, 2018 compared to the same period in 2017 primarily due to:


•	higher pricing for most of our products in our Acetyl Intermediates segment;

•

higher volume in our Engineered Materials segment, primarily related to Net sales generated from the nylon compounding division of Nilit Group ("Nilit") and from Omni Plastics, L.L.C. ("Omni Plastics") that we acquired in May 2017 and February 2018, respectively, as well as within our base business due to new project launches and pipeline growth. See Note 3 - Acquisitions, Dispositions and Plant Closures in the accompanying unaudited interim consolidated financial statements for further information; and


•	a favorable currency impact across all of our segments resulting from a strong Euro relative to the US dollar.

Operating profit increased $173 million, or 101.8%, for the three months ended March 31, 2018 compared to the same period in 2017 primarily due to:


•	higher Net sales; and

•

a favorable impact of $53 million to Other (charges) gains, net. During the three months ended March 31, 2017, we provided notice of termination of a contract with a key raw materials supplier at our ethanol production unit in Nanjing, China. As a result, we recorded a $27 million contract termination charge and an $18 million reduction to our non-income tax receivable, which did not recur in the current year. See Note 14 - Other (Charges) Gains, Net in the accompanying unaudited interim consolidated financial statements for further information;

Table of Contents

partially offset by:


•	higher raw material costs across most of our segments;


•	higher plant spending of $21 million in our Engineered Materials segment; and


•	higher functional and project spending of $15 million.

Our effective income tax rate for the three months ended March 31, 2018 was 15% compared to 23% for the same period in 2017. The lower effective income tax rate for the three months ended March 31, 2018 compared to the same period in 2017 is primarily due to the corporate tax rate reduction in the US from the TCJA and decreases in losses in jurisdictions not providing tax benefit.

In December 2017, TCJA was enacted and is effective January 1, 2018. ASC 740, Accounting for Income Taxes, requires companies to recognize the effects of tax law changes in the period of enactment. This overhaul of the US tax law made a number of substantial changes, including the reduction of the corporate tax rate from 35% to 21%, establishing a dividends received deduction for dividends paid by foreign subsidiaries to the US, elimination or limitation of certain deductions (interest, domestic production activities and executive compensation), imposing a mandatory tax on previously unrepatriated earnings accumulated offshore since 1986 and establishing global minimum income tax and base erosion tax provisions related to offshore activities and affiliated party payments.

Due to the timing of the new tax law and the substantial changes it brings, the Staff of the SEC issued SAB 118, which provides registrants a measurement period to report the impact of the new US tax law. During the measurement period, provisional amounts for the effects of the law are recorded to the extent a reasonable estimate can be made. To the extent that all information necessary is not available, prepared or analyzed, companies may recognize provisional estimated amounts for a period of up to one year following enactment of the TCJA.

For year-end 2017, we recorded provisional amounts for impacts of the new tax law including: the deemed repatriation tax on post 1986 accumulated earnings and profits, the deferred tax rate change effect of the new law, gross foreign tax credit carryforwards and related valuation allowances to offset foreign tax credit carryforwards. Certain items or estimates that result in impacts of the TCJA being provisional include: detailed foreign earnings calculations for 2017 and 2018, projected foreign cash balances for certain foreign subsidiaries and finalized computations of foreign tax credit availability. Finally, we consider it likely that further technical guidance regarding certain components of the new provisions included in the TCJA, as well as clarity regarding state income tax conformity to current federal tax code, may be issued. During the three months ended March 31, 2018, we recorded increases to provisional amounts for valuation allowances on foreign tax credits of $24 million. The changes in provisional amounts are primarily due to refined estimates of foreign source income and expense apportionment during the credit carryforward period. We will continue to refine provisional amounts for the impacts of the TCJA as more refined information and further guidance become available.

See Note 15 - Income Taxes in the accompanying unaudited interim consolidated financial statements for further information.

Our engineered materials business develops, produces and supplies a broad portfolio of high performance specialty polymers for automotive and medical applications, as well as industrial products and consumer electronics. Together with our strategic affiliates, our engineered materials business is a leading participant in the global specialty polymers industry. Our food ingredients business is a leading global supplier of acesulfame potassium for the food and beverage industry and is a leading producer of food protection ingredients, such as potassium sorbate and sorbic acid.

The pricing of products by the Engineered Materials segment is primarily based on the value of the material we produce and is largely independent of changes in the cost of raw materials. Therefore, in general, margins may expand or contract in response to changes in raw material costs.

Three Months Ended March 31, 2018 Compared to Three Months Ended March 31, 2017

Net sales increased for the three months ended March 31, 2018 compared to the same period in 2017 primarily due to:


•	higher volume primarily due to Net sales generated from Nilit and Omni Plastics, which represents approximately three-fourths of the increase in volume;


•	higher volume within our base business driven by new project launches and pipeline growth, which represents the remainder of the volume growth;


•	a favorable currency impact resulting from a strong Euro relative to the US dollar; and


•	higher pricing for most of our products due to customer mix.

Operating profit increased for the three months ended March 31, 2018 compared to the same period in 2017 primarily due to:


•	higher Net sales;

partially offset by:


•	higher plant spending of $21 million, primarily related to our acquisitions of Nilit and Omni Plastics, as these acquired businesses incur ongoing plant spending, as well as increased distribution costs; and


•	higher raw material costs, primarily related to methanol.

Equity in net earnings (loss) of affiliates increased for the three months ended March 31, 2018 compared to the same period in 2017 primarily due to:


•	an increase in equity investment in earnings of $9 million from our Ibn Sina strategic affiliate as a result of higher methyl tertiary-butyl ether ("MTBE") pricing and an increase in our indirect economic ownership from 25% to 32.5% as a result of the startup of its polyoxymethylene production facility in Saudi Arabia during the three months ended December 31, 2017.

On February 1, 2018, we completed the acquisition of 100% of the ownership interests of Omni Plastics. Omni Plastics specializes in custom compounding of various engineered thermoplastic materials. The acquisition further strengthens our global asset base by adding compounding capacity in the Americas. See Note 3 - Acquisitions, Dispositions and Plant Closures in the accompanying unaudited interim consolidated financial statements for further information.

Our Acetate Tow segment serves consumer-driven applications. We are a leading global producer and supplier of acetate tow and acetate flake, primarily used in filter products applications.

The pricing of products within the Acetate Tow segment is sensitive to demand and is primarily based on the value of the material we produce. Many sales in these businesses are conducted under contracts with pricing for one or more years. As a result, margins may expand or contract in response to changes in raw material costs over these similar periods, and we may be unable to adjust pricing also due to other factors, such as the intense level of competition in the industry.

Three Months Ended March 31, 2018 Compared to Three Months Ended March 31, 2017

Net sales decreased for the three months ended March 31, 2018 compared to the same period in 2017 primarily due to:


•	lower acetate tow pricing and volume due to lower global industry utilization.

Operating profit decreased for the three months ended March 31, 2018 compared to the same period in 2017 primarily due to:


•	lower Net sales.

In June 2017, Celanese, through various subsidiaries, entered into an agreement with affiliates of The Blackstone Group L.P. (the "Blackstone Entities") to form a joint venture which would combine substantially all of the operations of our cellulose derivatives business and the operations of the Rhodia Acetow cellulose acetate business formerly operated by Solvay S.A. and acquired by the Blackstone Entities in June 2017. The parties were subsequently unable to reach an agreement with the European Commission on acceptable conditions to allow the proposed joint venture to proceed. The demands by the European Commission eliminated the advantages at the heart of the transaction. As a result, on March 19, 2018, we and the Blackstone Entities abandoned our agreement to form the proposed joint venture.

Our Industrial Specialties segment includes our emulsion polymers and EVA polymers businesses. Our emulsion polymers business is a leading global producer of vinyl acetate-based emulsions and develops products and application technologies to improve performance, create value and drive innovation in applications such as paints and coatings, adhesives, construction, glass fiber, textiles and paper. Our EVA polymers business is a leading North American manufacturer of a full range of specialty ethylene vinyl acetate ("EVA") resins and compounds as well as select grades of low-density polyethylene. EVA polymers products are used in many applications, including flexible packaging films, lamination film products, hot melt adhesives, automotive parts and carpeting.

Pricing of our products within Industrial Specialties is influenced by changes in the cost of raw materials. Therefore, in general, there is a direct correlation between the cost of raw materials and our Net sales for most Industrial Specialties products. This impact to pricing typically lags changes in raw material costs over months or quarters.

Three Months Ended March 31, 2018 Compared to Three Months Ended March 31, 2017

Net sales increased for the three months ended March 31, 2018 compared to the same period in 2017 primarily due to:


•	higher pricing in our emulsion polymers business due to higher raw material costs for vinyl acetate monomer ("VAM") across all regions; and


•	a favorable currency impact resulting from a strong Euro relative to the US dollar.

Operating profit decreased for the three months ended March 31, 2018 compared to the same period in 2017 primarily due to:


•	higher raw material costs of $18 million, primarily VAM;

largely offset by:


•	higher Net sales.

Our Acetyl Intermediates segment includes our intermediate chemistry business which produces and supplies acetyl products, including acetic acid, VAM, acetic anhydride and acetate esters. These products are generally used as starting materials for colorants, paints, adhesives, coatings and medicines. This business segment also produces organic solvents and intermediates for pharmaceutical, agricultural and chemical products.

Pricing of acetic acid, VAM and other acetyl products is influenced by industry utilization rates and changes in the cost of raw materials. Therefore, in general, there is a directional correlation between these factors and our Net sales for most intermediate chemistry products. This impact to pricing typically lags changes in raw material costs over months or quarters.

Three Months Ended March 31, 2018 Compared to Three Months Ended March 31, 2017

Net sales increased for the three months ended March 31, 2018 compared to the same period in 2017 primarily due to:


•	higher pricing due to higher industry utilization rates, which positively impacted pricing for most of our products;


•	a favorable currency impact resulting from a strong Euro relative to the US dollar; and


•	higher volume for acetic acid and VAM, which represents all of the increase in volume, primarily due to higher demand in China.

Operating profit increased for the three months ended March 31, 2018 compared to the same period in 2017 primarily due to:


•	higher Net sales; and

•

partially offset by:


•	higher raw material costs, primarily for methanol.

Liquidity and Capital Resources

Our primary source of liquidity is cash generated from operations, available cash and cash equivalents and dividends from our portfolio of strategic investments. In addition, as of March 31, 2018, we have $803 million available for borrowing under our senior unsecured revolving credit facility and $3 million available under our accounts receivable securitization facility to assist, if required, in meeting our working capital needs and other contractual obligations.

While our contractual obligations, commitments and debt service requirements over the next several years are significant, we continue to believe we will have available resources to meet our liquidity requirements, including debt service, for the next twelve months. If our cash flow from operations is insufficient to fund our debt service and other obligations, we may be required to use other means available to us such as increasing our borrowings, reducing or delaying capital expenditures, seeking additional capital or seeking to restructure or refinance our indebtedness. There can be no assurance, however, that we will continue to generate cash flows at or above current levels.

Total cash outflows for capital expenditures are expected to be in the range of $300 million to $350 million in 2018 primarily due to additional investments in growth opportunities in our Engineered Materials and Acetyl Intermediates segments.

On a stand-alone basis, Celanese and its immediate 100% owned subsidiary, Celanese US, have no material assets other than the stock of their subsidiaries and no independent external operations of their own. Accordingly, they generally depend on the cash flow of their subsidiaries and their ability to pay dividends and make other distributions to Celanese and Celanese US in order to meet their obligations, including their obligations under senior credit facilities and senior notes and to pay dividends on our Series A common stock, par value $0.0001 per share ("Common Stock").

Cash Flows

Cash and cash equivalents decreased $86 million to $490 million as of March 31, 2018 compared to December 31, 2017. As of March 31, 2018, $343 million of the $490 million of cash and cash equivalents was held by our foreign subsidiaries. Under the TCJA, we have incurred a charge associated with the repatriation of previously unremitted foreign earnings, including foreign held cash. These funds are largely accessible, if needed in the US to fund operations. See Note 15 - Income Taxes in the accompanying unaudited interim consolidated financial statements for further information.


•	Net Cash Provided by (Used in) Operating Activities

Net cash provided by operating activities decreased $49 million to $143 million for the three months ended March 31, 2018 compared to $192 million for the same period in 2017. Net cash provided by operating activities for the three months ended March 31, 2018 decreased primarily due to:


•	unfavorable trade working capital of $153 million primarily due to an increase in trade receivables as a result of an increase in Net sales in our Acetyl Intermediates segment; and


•	an increase of $27 million in cash taxes paid and incentive compensation;

mostly offset by:


•	an increase in net earnings.


•	Net Cash Provided by (Used in) Investing Activities

Net cash used in investing activities increased $171 million to $235 million for the three months ended March 31, 2018 compared to $64 million for the same period in 2017, primarily due to:


•	a net cash outflow of $144 million related to the acquisition of Omni in February 2018; and


•	an increase of $24 million in capital expenditures related to growth opportunities in our Engineered Materials segment.

Table of Contents


•	Net Cash Provided by (Used in) Financing Activities

Net cash used in financing activities decreased $268 million from $270 million for the three months ended March 31, 2017 to $2 million for the three months ended March 31, 2018, primarily due to:


•	a decrease of $128 million in share repurchases of our Common Stock; and


•	an increase in net borrowings on short-term debt of $115 million, primarily as a result of borrowings under our revolving credit facility during the three months ended March 31, 2018.

Critical Accounting Policies and Estimates

Our unaudited interim consolidated financial statements are based on the selection and application of significant accounting policies. The preparation of unaudited interim consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements and the reported amounts of Net sales, expenses and allocated charges during the reporting period. Actual results could differ from those estimates. However, we are not currently aware of any reasonably likely events or circumstances that would result in materially different results.

We describe our significant accounting policies in Note 2 - Summary of Accounting Policies, of the Notes to the Consolidated Financial Statements included in our 2017 Form 10-K. We discuss our critical accounting policies and estimates in MD&A in our 2017 Form 10-K.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended, as of the end of the period covered by this report. Based on that evaluation, as of March 31, 2018, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective.

Changes in Internal Control Over Financial Reporting

On February 1, 2018, we acquired 100% of the ownership interests of Omni Plastics, L.L.C. and its subsidiaries. See Note 3 - Acquisitions, Dispositions and Plant Closures in the accompanying unaudited interim consolidated financial statements for further information.

During the period covered by this report, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
