Notes to Consolidated Financial Statements

(unaudited)

1. Basis of Presentation and Summary of Significant Accounting Policies

Adient is a global leader in the automotive seating supplier industry. Adient has a leading market position in the Americas, Europe and China, and has longstanding relationships with the largest global original equipment manufacturers, or OEMs, in the automotive space. Adient's proprietary technologies extend into virtually every area of automotive seating solutions, including complete seating systems, frames, mechanisms, foam, head restraints, armrests, trim covers and fabrics. Adient is an independent seat supplier with global scale and the capability to design, develop, engineer, manufacture, and deliver complete seat systems and components in every major automotive producing region in the world. Adient also participates in the automotive interiors market primarily through its global automotive interiors joint venture in China, Yanfeng Global Automotive Interior Systems Co., Ltd., or YFAI.

Basis of Presentation

The unaudited consolidated financial statements of Adient have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. These interim consolidated financial statements include all adjustments (consisting of normal recurring adjustments, except as otherwise disclosed) that management believes are necessary for a fair statement of the results of operations, financial position and cash flows of Adient for the interim periods presented. Interim results are not necessarily indicative of full-year results.

Principles of Consolidations

Adient consolidates its wholly-owned subsidiaries and those entities in which it has a controlling interest. Investments in partially-owned affiliates are accounted for by the equity method when Adient's interest exceeds 20% and does not have a controlling interest.

Consolidated VIEs

Based upon the criteria set forth in the Financial Accounting Standards Board (the FASB) Accounting Standards Codification (ASC) 810, "Consolidation," Adient has determined that it was the primary beneficiary in two variable interest entities (VIEs) for the reporting periods ended December 31, 2018 and September 30, 2018, respectively, as Adient absorbs significant economics of the entities and has the power to direct the activities that are considered most significant to the entities.

The two VIEs manufacture seating products in North America for the automotive industry. Adient funds the entities' short-term liquidity needs through revolving credit facilities and has the power to direct the activities that are considered most significant to the entities through its key customer supply relationships.

The carrying amounts and classification of assets (none of which are restricted) and liabilities included in Adient's consolidated statements of financial position for the consolidated VIEs are as follows:

	December 31,		September 30,
(in millions)	2018		2018
Current assets	$	221	$	270
Noncurrent assets	42		43
Total assets	$	263	$	313
Current liabilities	$	197	$	252
Total liabilities	$	197	$	252

	Three Months Ended December 31,
(in millions, except per share data)	2018			2017
Numerator:
Net income (loss) attributable to Adient	$	(17	)	$	(216	)
Denominator:

Diluted	$	(0.18	)	$	(2.32	)

Potentially dilutive securities whose effect would have been antidilutive are excluded from the computation of diluted earnings per share. The impact of excluding antidilutive securities was insignificant for all periods presented.

New Accounting Pronouncements

Standards Adopted During Fiscal 2019

ASU 2014-09, Revenue - Revenue from Contracts with Customers. On October 1, 2018, Adient adopted Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("ASC 606"), and all the related amendments using the modified retrospective method as applied to all customer contracts that were not completed as of October 1, 2018. As a result, financial information for reporting periods beginning on or after October 1, 2018 are presented in accordance with ASC 606. Comparative financial information for reporting periods beginning prior to October 1, 2018 has not been adjusted and continues to be reported in accordance with Adient's revenue recognition policies prior to the adoption of ASC 606. Adient did not record a cumulative adjustment related to the adoption of ASC 606, and the effects of adoption were not significant. Refer to Note 2, "Revenue Recognition," of the notes to the consolidated financial statements for information related to Adient's adoption of ASU 2014-09.

ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. On October 1, 2018, Adient adopted the amendments to ASU 2017-07 that improve the presentation of net periodic pension and postretirement benefit costs and retrospectively adopted the presentation of service cost separate from the other components of net periodic costs. The interest cost, expected return on assets, amortization of prior service costs, net remeasurement, and other costs have been reclassified from cost of sales and selling, general and administrative expenses to other pension expense (income). Adient elected to apply the practical expedient which allows reclassification of amounts previously disclosed in the retirement benefits note as the basis for applying retrospective presentation for comparative periods as it is impracticable to determine the disaggregation of the cost components for amounts capitalized and amortized in those periods. On a prospective basis, the other components of net periodic benefit costs will not be included in amounts capitalized in inventory or property, plant, and equipment.

The effect of the retrospective presentation change related to the net periodic cost of Adient's defined benefit pension and other postretirement employee benefits ("OPEB") plans on the consolidated statements of income (loss) for the three months ended December 31, 2017 resulted in a $1 million increase to cost of sales, a $1 million decrease to gross profit, a $1 million decrease to earnings (loss) before interest and income taxes and a $1 million increase to other pension expense (income) line items in the condensed consolidated statements of income. As a result of presenting certain pension costs as non-operating items, adjusted EBITDA decreased by $1 million in the Seating segment for the three months ended December 31, 2017.

Adient also adopted the following standards during fiscal 2019, none of which had a material impact to the consolidated financial statements or consolidated financial statement disclosures:

ASU 2018-08, Not for Profit Entities: Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made	ASU 2018-08 is intended to clarify and improve the scope and the accounting guidance for contributions received and contributions made. The amendments in ASU No. 2018-08 should assist entities in (1) evaluating whether transactions should be accounted for as contributions (nonreciprocal transaction) within the scope of Topic 958, Not-for-Profit Entities, or as exchange (reciprocal) transactions subject to other guidance and (2) determining whether a contribution is conditional. This amendment applies to all entities that make or receive grants or contributions.	October 1, 2018
ASU 2018-15, Intangibles-Goodwill and Other-Internal Use Software: Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract	The amendments in ASU 2018-15 require implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance. The amendments also require an entity to disclose the nature of its hosting arrangements and adhere to certain presentation requirements in its balance sheet, income statement and statement of cash flows.	ASU No. 2018-15 is effective for Adient for the quarter ending December 31, 2019, with early adoption permitted. Adient early adopted ASU No. 2018-15 effective October 1, 2018.
ASU 2018-16, Derivatives and Hedging: Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes	The amendments in this Update permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the UST, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the SIFMA Municipal Swap Rate.	October 1, 2018

Adient plc | Form 10-Q | 9

Standards Effective After Fiscal 2019

Adient believes that the ASU summarized below, which is effective fiscal 2020, could significantly impact the consolidated financial statements:

Standard Pending Adoption	Description	Anticipated Impact	Effective Date
ASU 2016-02, 2018-01, 2018-10 and 2018-11	The standard requires that a lessee recognize on its balance sheet right-of-use assets and corresponding liabilities resulting from leasing transactions, as well as additional financial statement disclosures. Currently, U.S. GAAP only requires balance sheet recognition for leases classified as capital leases. The provisions of this update apply to substantially all leased assets.	Adient is currently evaluating the impact this standard will have on its consolidated financial position, results of operations and cash flows and expects the impact to the consolidated balance sheet to be significant.	October 1, 2019

Adient plc | Form 10-Q | 10

Adient has considered the ASUs summarized below, effective after fiscal 2019, none of which are expected to significantly impact the consolidated financial statements:

Standard Adopted	Description	Date Effective
ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments	ASU 2016-13 changes the impairment model for financial assets measured at amortized cost, requiring presentation at the net amount expected to be collected. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts. Available-for-sale debt securities with unrealized losses will now be recorded through an allowance for credit losses.	October 1, 2020
ASU 2018-07, Compensation-Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting	ASU 2018-07 expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606.	October 1, 2019
ASU 2018-13, Fair Value Measurement: Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement	The amendments in ASU 2018-13 eliminate, add, and modify certain disclosure requirements for fair value measurements. ASU 2018-13 will be effective for Adient for the quarter ending December 31, 2019, with early adoption permitted for either the entire ASU or only the provisions that eliminate or modify requirements. The amendments with respect to changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty are to be applied prospectively. All other amendments are to be applied retrospectively to all periods presented.	October 1, 2019
ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General: Disclosure Framework - Changes to the Disclosure Requirements for Defned Benefit Plans	The amendments in ASU 2018-14 eliminate, add, and modify certain disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The guidance is to be applied on a retrospective basis to all periods presented.	October 1, 2020
ASU 2018-17, Consolidated: Targeted Improvements to Related Party Guidance for Variable Interest Entities	The amendments in this Update affect reporting entities that are required to determine whether they should consolidate a legal entity under the guidance within the Variable Interest Entities Subsections of Subtopic 810-10, Consolidation-Overall.	October 1, 2019
ASU 2018-18, Collaborative Arrangements: Clarifying the Interaction between Topic 808 and Topic 606	The amendments in this Update make targeted improvements to generally accepted accounting principles (GAAP) for collaborative arrangements as follows: 1) Clarify that certain transactions between collaborative arrangement participant is a customer in the context of a unit of account. In those situations, all the guidance in Topic 606 should be applied, including recognition, measurement, presentation, and disclosure requirements. 2) Add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606 (that is, a distinct good or service) when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of Topic 606. 3) Require that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer.	October 1, 2019

Adient plc | Form 10-Q | 11

2. Revenue Recognition

Adient adopted Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (ASC 606), and all the related amendments using the modified retrospective method as applied to all customer contracts that were not completed as of October 1, 2018. As a result, financial information for reporting periods beginning on or after October 1, 2018 are presented in accordance with ASC 606. Comparative financial information for reporting periods beginning prior to October 1, 2018 has not been adjusted and continues to be reported in accordance with Adient's revenue recognition policies prior to the adoption of ASC 606. Adient did not record a cumulative adjustment related to the adoption of ASC 606 as the effects of adoption were not significant. The majority of Adient's nonconsolidated partially-owned affiliates will adopt ASC 606 on October 1, 2019.

Adient generates revenue through the sale of automotive seating solutions, including complete seating systems and the components of complete seating systems.

In a typical arrangement with the customer, purchase orders are issued for pre-production activities which consist of engineering, design and development, tooling and prototypes for the manufacture and delivery of component parts. Adient has concluded that these activities are not in the scope of ASC 606 and for that reason, there have been no changes to how Adient accounts for reimbursable pre-production costs.

Adient provides production and service parts to its customers under awarded multi-year programs. The duration of a program is generally consistent with the life cycle of a vehicle, however, the program can be canceled at any time without cause by the customer. Programs awarded to Adient to supply parts to its customers do not contain a firm commitment by the customer for volume or price and do not reach the level of a performance obligation until Adient receives either a purchase order and/or a materials release from the customer for a specific number of parts at a specified price, at which point an enforceable contract exists. Sales revenue is generally recognized at the point in time when parts are shipped and control has transferred to the customer, at which point an enforceable right to payment exists. Contracts may provide for annual price reductions over the production life of the awarded program, and prices are adjusted on an ongoing basis to reflect changes in product content/cost and other commercial factors. The amount of revenue recognized reflects the consideration that Adient expects to be entitled to in exchange for such products based on purchase orders, annual price reductions and ongoing price adjustments (some of which are accounted for as variable consideration and subject to being constrained, but which are not expected to significantly change under ASC 606), net of the impact, if any, of consideration paid to the customer.

Adient has elected to continue to include shipping and handling fees billed to customers in revenue, while including costs of shipping and handling in cost of sales. Taxes collected from customers are excluded from revenue and credited directly to obligations to the appropriate government agencies. Payment terms with customers are established based on customary industry and regional practices. Adient has evaluated the terms of its arrangements and determined that they do not contain significant financing components.

Contract assets primarily relate to the right to consideration for work completed, but not billed at the reporting date on contracts with customers. The contracts assets are transferred to receivables when the rights become unconditional. Contract liabilities primarily relate to contracts where advance payments or deposits have been received, but performance obligations have not yet been satisfied and revenue has not been recognized. No significant contract assets or liabilities were identified upon adoption of ASC606 or at December 31, 2018. As described above, the issuance of a purchase order and/or a materials release by the customer represents the point at which an enforceable contract with the customer exists. Therefore, Adient has elected to apply the practical expedient in ASC 606, paragraph 606-10-50-14 and does not disclose information about the remaining performance obligations that have an original expected duration of one year or less.

3. Acquisitions and Divestitures

Acquisitions

Adient's consolidated affiliate, Adient Aerospace, LLC ("Adient Aerospace"), became operational on October 11, 2018 after securing regulatory approvals. Adient's ownership position in Adient Aerospace is 50.01%. Adient Aerospace will develop, manufacture, and sell a portfolio of seating products to airlines and aircraft leasing companies for installation on Boeing and other OEM commercial airplanes, for both production line-fit and retrofit configurations. Adient Aerospace's results are included within the Seating segment. Initial contributions of $28 million were made during the first quarter of fiscal 2019.

Assets Held for Sale

During fiscal 2018, Adient committed to a plan to sell its Detroit, Michigan properties and its airplanes and actively marketed the sale of these assets. As a result, these assets were classified as assets held for sale and were required to be adjusted to the lower of fair value less cost to sell or carrying value. This resulted in an impairment charge of $49 million which was recorded within restructuring and impairment costs on the consolidated statement of income (loss) during fiscal 2018, of which $39 million related to Seating assets and $10 million related to corporate assets. The impairment was measured using third party sales pricing to determine fair values of the assets. The inputs utilized in the analyses are classified as Level 3 inputs within the fair value hierarchy as defined in ASC 820, "Fair Value Measurement." During the fourth quarter of fiscal 2018, one airplane was sold for $36 million. During the first quarter of fiscal 2019, both the Detroit, Michigan properties and remaining airplane were sold for approximately $35 million.

6. Product Warranties

Adient offers warranties to its customers depending upon the specific product and terms of the customer purchase agreement. A typical warranty program requires that Adient replace defective products within a specified time period from the date of sale. Adient records an estimate for future warranty-related costs based on actual historical return rates and other known factors. Based on analysis of return rates and other factors, Adient's warranty provisions are adjusted as necessary. Adient monitors its warranty activity and adjusts its reserve estimates when it is probable that future warranty costs will be different than those estimates. Adient's product warranty liability is recorded in the consolidated statements of financial position in other current liabilities.

The changes in Adient's total product warranty liability are as follows:

On July 27, 2016, Adient Global Holdings Ltd ("AGH"), a wholly owned subsidiary of Adient, entered into a credit agreement providing for commitments with respect to a $1.5 billion revolving credit facility (undrawn at December 31, 2018 and September 30, 2018, respectively) and a $1.5 billion Term Loan A facility (the "Original Credit Facilities"). The Original Credit Facilities mature in July 2021. Until the Term Loan A maturity date, amortization of the funded Term Loan A is required in an amount per quarter equal to 1.25% of the original principal amount prior to July 27, 2019 and 2.5% in each quarter thereafter prior to final maturity. The Original Credit Facilities contain covenants that include, among other things and subject to certain significant exceptions, restrictions on Adient's ability to declare or pay dividends, make certain payments in respect of the notes, create liens, incur additional indebtedness, make investments, engage in transactions with affiliates, enter into agreements restricting Adient's subsidiaries' ability to pay dividends, dispose of assets and merge or consolidate with any other person. The Term Loan A facility also requires mandatory prepayments in connection with certain non-ordinary course asset sales and insurance recovery and condemnation events, among other things, and subject in each case to certain significant exceptions.

Adient plc | Form 10-Q | 15

On November 6, 2018, Adient entered into an amendment to the Original Credit Facilities (“First Amended Credit Facilities") whereby the financial maintenance covenant was amended to require Adient to maintain a total net leverage ratio equal to or less than 4.5x adjusted EBITDA (previously 3.5x adjusted EBITDA), with step down provisions starting in the quarter ending December 31, 2020. The amendment also expanded the upper range of interest rate margins such that the drawn portion of the First Amended Credit Facilities will bear interest based on LIBOR plus a margin between 1.25% - 2.50% (previously 1.25% - 2.25%), based on Adient’s total net leverage ratio. No other terms were impacted by the first amendment. On February 6, 2019, Adient entered into an amendment to the First Amended Credit Facilities (“Second Amended Credit Facilities") whereby the financial maintenance covenant contained in the First Amended Credit Facilities was amended to require Adient to maintain a first lien secured net leverage ratio equal to or less than 2.5x adjusted EBITDA as of the last day of each quarter, with step down provisions starting on September 30, 2020. The amendment also added a new tier to the pricing schedule that will be applicable when the total net leverage ratio exceeds 4.0x adjusted EBITDA and amended certain other definitions, negative covenants and other terms within the credit facility.

The full amount of the Term Loan A facility was drawn in the fourth quarter of fiscal 2016. These funds were transferred to the former Parent at the time of the draw and were reflected within net transfers to the former Parent in the consolidated statement of cash flow during the fourth quarter of fiscal 2016. In February 2017, Adient repaid $100 million of the Term Loan A facility. In May 2017, Adient repaid another $200 million of the Term Loan A facility. The total amount repaid was treated as a prepayment of the quarterly mandatory principle amortization for the period between March 2017 and June 2020 resulting in no required principal payment until June 2020.

AGH will pay a commitment fee on the unused portion of the commitments under the revolving credit facility based on the total net leverage ratio of Adient, ranging from 0.15% to 0.45%.

On August 19, 2016, AGH issued $0.9 billion aggregate principal amount of 4.875% USD-denominated unsecured notes due 2026 and €1.0 billion aggregate principal amount of 3.50% unsecured notes due 2024, in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended. The proceeds of the notes were used, together with the Term Loan A facility, to pay a distribution to the former Parent, with the remaining proceeds used for working capital and general corporate purposes.

On May 29, 2017, Adient Germany Ltd. & Co. KG, a wholly owned subsidiary of Adient, borrowed €165 million in an unsecured term loan from the European Investment Bank due in 2022. The loan bears interest at the 6-month EURIBOR rate plus 90 basis points. Loan proceeds were used to repay $200 million of the Term Loan A.

Net Financing Charges

8. Derivative Instruments and Hedging Activities

Adient selectively uses derivative instruments to reduce Adient's market risk associated with changes in foreign currency. Under Adient's policy, the use of derivatives is restricted to those intended for hedging purposes; the use of any derivative instrument for speculative purposes is strictly prohibited. A description of each type of derivative utilized to manage Adient's risk is included in the following paragraphs. In addition, refer to Note 9, "Fair Value Measurements," of the notes to consolidated financial statements for information related to the fair value measurements and valuation methods utilized by Adient for each derivative type.

Adient has global operations and participates in the foreign exchange markets to minimize its risk of loss from fluctuations in foreign currency exchange rates. Adient primarily uses foreign currency exchange contracts to hedge certain foreign exchange rate exposures. Adient hedges 70% to 90% of the nominal amount of each of its known foreign exchange transactional exposures. Gains and losses on derivative contracts offset gains and losses on underlying foreign currency exposures. These contracts have been designated as cash flow hedges under ASC 815, "Derivatives and Hedging," and the effective portion of the hedge gains or losses due to changes in fair value are initially recorded as a component of accumulated other comprehensive income (AOCI) and are subsequently reclassified into earnings when the hedged transactions occur and affect earnings. Any ineffective portion of the hedge is reflected in the consolidated statements of income. These contracts were highly effective in hedging the variability in future cash flows attributable to changes in currency exchange rates at December 31, 2018 and September 30, 2018, respectively.

Adient selectively uses equity swaps to reduce market risk associated with certain of its stock-based compensation plans, such as its deferred compensation plans. The equity swaps are recorded at fair value. Changes in fair value of the equity swaps are reflected in the consolidated statements of income within selling, general and administrative expenses.

As of December 31, 2018, the €1.0 billion aggregate principal amount of 3.50% euro-denominated unsecured notes due 2024 was designated as a net investment hedge to selectively hedge portions of Adient's net investment in Europe. The currency effects of Adient's euro-denominated bonds are reflected in AOCI account within shareholders' equity attributable to Adient where they offset gains and losses recorded on Adient's net investment in Europe.

Adient entered into cross-currency interest rate swaps during fiscal 2018 to selectively hedge portions of its net investment in Europe. The currency effects of the cross-currency interest rate swaps are reflected in the AOCI account within shareholders' equity attributable to Adient, where they offset gains and losses recorded on Adient's net investment in Europe. As of December 31, 2018, Adient had two cross-currency interest rate swaps outstanding totaling approximately €160 million designated as net investment hedges in Adient's net investment in Europe.

The following table presents the location and fair values of derivative instruments and other amounts used in hedging activities included in Adient's consolidated statements of financial position:

Adient enters into International Swaps and Derivatives Associations (ISDA) master netting agreements with counterparties that permit the net settlement of amounts owed under the derivative contracts. The master netting agreements generally provide for net settlement of all outstanding contracts with a counterparty in the case of an event of default or a termination event. Adient has not elected to offset the fair value positions of the derivative contracts recorded in the consolidated statements of financial position. Collateral is generally not required of Adient or the counterparties under the master netting agreements. As of both December 31, 2018 and September 30, 2018, no cash collateral was received or pledged under the master netting agreements.

The gross and net amounts of derivative instruments and other amounts used in hedging activities are as follows:

	Assets						Liabilities
(in millions)	December 31, 2018			September 30, 2018			December 31, 2018			September 30, 2018

9. Fair Value Measurements

ASC 820, "Fair Value Measurement," defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 also establishes a three-level fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability as follows:

Level 1: Observable inputs such as quoted prices in active markets;

Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and

Level 3: Unobservable inputs where there is little or no market data, which requires the reporting entity to develop its own assumptions.

ASC 820 requires the use of observable market data, when available, in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.

Recurring Fair Value Measurements

The following tables present Adient's fair value hierarchy for those assets and liabilities measured at fair value:

	Fair Value Measurements Using:

Valuation Methods

Foreign currency exchange derivatives Adient selectively hedges anticipated transactions that are subject to foreign exchange rate risk primarily using foreign currency exchange hedge contracts. The foreign currency exchange derivatives are valued under a market approach using publicized spot and forward prices. Changes in fair value on foreign exchange derivatives accounted for as hedging instruments under ASC 815 are initially recorded as a component of AOCI and are subsequently reclassified into earnings when the hedged transactions occur and affect earnings. These contracts were highly effective in hedging the variability in future cash flows attributable to changes in currency exchange rates at December 31, 2018 and September 30, 2018, respectively. The changes in fair value of foreign currency exchange derivatives not designated as hedging instruments under ASC 815 are recorded in the consolidated statements of income.

Equity swaps Adient selectively uses equity swaps to reduce market risk associated with certain of its stock-based compensation plans, such as its deferred compensation plans. The equity swaps are recorded at fair value. Changes in fair value of the equity swaps are reflected in the consolidated statements of income within selling, general and administrative expenses.

Cross-currency interest rate swaps Adient selectively uses cross-currency interest rate swaps to hedge portions of its net investment in Europe.

The fair value of cash and cash equivalents, accounts receivable, short-term debt and accounts payable approximate their carrying values. The fair value of long-term debt, which was $3.0 billion and $3.3 billion at December 31, 2018 and September 30, 2018, respectively, was determined primarily using market quotes classified as Level 1 inputs within the ASC 820 fair value hierarchy.

related primarily to information technology assets within the Seating segment that will not be used going forward by Adient. The restructuring actions are expected to be substantially complete in fiscal 2021.

Since the announcement of the 2016 Plan in fiscal 2016, Adient has experienced lower employee severance and termination benefit cash payouts than previously calculated of approximately $20 million, due to changes in cost reduction actions. The planned workforce reductions disclosed for the 2016 Plan have been updated for Adient's revised actions.

The following table summarizes the changes in Adient's 2016 Plan reserve:

(in millions)	Employee Severance and Termination Benefits			Currency Translation		Total
Balance at September 30, 2018	$	71		$	4	$	75
Utilized—cash	(2		)	—		(2		)
Balance at December 31, 2018	$	69		$	4	$	73

Adient's fiscal 2019, 2018, 2017 and 2016 restructuring plans included workforce reductions of approximately 6,800. Restructuring charges associated with employee severance and termination benefits are paid over the severance period granted to each employee or on a lump sum basis in accordance with individual severance agreements. As of December 31, 2018, approximately 4,300 of the employees have been separated from Adient pursuant to the restructuring plans. In addition, the restructuring plans included fourteen plant closures. As of December 31, 2018, nine of the fourteen plants have been closed.

Adient's management closely monitors its overall cost structure and continually analyzes each of its businesses for opportunities to consolidate current operations, improve operating efficiencies and locate facilities in low cost countries in close proximity to customers. This ongoing analysis includes a review of its manufacturing, engineering, purchasing and administrative functions, as well as the overall global footprint for all its businesses. Because of the importance of new vehicle sales by major automotive manufacturers to operations, Adient is affected by the general business conditions in the automotive industry. Future adverse developments in the automotive industry could impact Adient's liquidity position, lead to impairment charges and/or require additional restructuring of its operations.

13. Income Taxes

In calculating the provision for income taxes, Adient uses an estimate of the annual effective tax rate based upon the facts and circumstances known at each interim period. On a quarterly basis, the actual effective tax rate is adjusted, as appropriate, based on changes in facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter. For the three months ended December 31, 2018, Adient’s effective tax rate was 48%. The effective rate was higher than the statutory rate of 12.5% primarily due to the impact of recognizing no tax benefit for losses in jurisdictions with valuation allowances, partially offset by a tax rate change in China. For the three months ended December 31, 2017, Adient’s effective tax rate was 384%. The effective rate was higher than the statutory rate of 12.5% primarily due to the charge to recognize the impact of the U.S. tax reform legislation and unfavorable foreign exchange.

Valuation Allowances

As a result of the Company's first quarter fiscal 2019 analysis of the realizability of its worldwide deferred tax assets, and after considering tax planning initiatives and other positive and negative evidence, Adient determined that no material changes to valuation allowances were required.

Adient reviews the realizability of its deferred tax assets on a quarterly basis, or whenever events or changes in circumstances indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results of the legal entity or combined group recording the net deferred tax asset are considered, along with any other positive or negative evidence. All of the factors that Adient considers in evaluating whether and when to establish or release all or a portion of the deferred tax asset valuation allowance involve significant judgment.

Since future financial results may differ from previous estimates, periodic adjustments to Adient's valuation allowances may be necessary. If Adient's operating performance continues to be negatively impacted and actual results differ significantly from current or prior estimates, Adient may conclude that it is more likely than not that a material portion of our deferred tax assets will not be

Adient plc | Form 10-Q | 24

realized. As such, it is possible that a change to valuation allowances in certain jurisdictions may result in a material increase to income tax expense during the next twelve months. In addition, the effective tax rate in subsequent periods would also increase.

Uncertain Tax Positions

At December 31, 2018, Adient had gross tax effected unrecognized tax benefits of $283 million. If recognized, $132 million of Adient's unrecognized tax benefits would impact the effective tax rate. Total net accrued interest at December 31, 2018 was approximately $6 million (net of tax benefit). The interest and penalties accrued during the three months ended December 31, 2018 was not material. Adient recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense.

Impacts of Tax Legislation and Change in Statutory Tax Rates

During the first quarter of fiscal 2019, Adient completed its accounting for the Tax Cuts and Jobs Act Base Erosion and Anti-avoidance Tax valuation allowance resulting in no change to the $100 million income tax impact estimated in fiscal 2018.

During the first quarter of fiscal 2019, Guangzhou Adient Automotive Seating Co., Ltd. ("GAAS”) was approved for High and New Tech Enterprise status for the three-year period of 2018 to 2020, thereby reducing their tax rate from 25% to 15%. As a result, a $7 million income tax benefit was recorded on the reduction of deferred tax liabilities and a reduction of 2018 calendar year income taxes.

Other tax legislation was adopted during the quarter in various jurisdictions, which did not have a material impact on Adient’s consolidated financial statements.

14. Segment Information

Adient evaluates the performance of its reportable segments using an adjusted EBITDA metric defined as income before income taxes and noncontrolling interests, excluding net financing charges, qualified restructuring and impairment costs, restructuring related-costs, incremental "Becoming Adient" costs, separation costs, net mark-to-market adjustments on pension and postretirement plans, transaction gains/losses, purchase accounting amortization, depreciation, stock-based compensation and other non-recurring items ("Adjusted EBITDA"). Also, certain corporate-related costs are not allocated to the segments. The reportable segments are consistent with how management views the markets served by Adient and reflect the financial information that is reviewed by its chief operating decision maker. Adient has three reportable segments for financial reporting purposes:

• Seating: This segment produces complete seat systems for automotive and other mobility applications, as well as certain components of complete seat systems, such as foam, trim and fabric.

• Seat Structures & Mechanisms (SS&M): This segment produces seat structures and mechanisms for inclusion in complete seat systems that are produced by Adient or others.

• Interiors: This segment, derived from Adient's global automotive interiors joint ventures, produces instrument panels, floor consoles, door panels, overhead consoles, cockpit systems, decorative trim and other products.

16. Commitments and Contingencies

Adient accrues for potential environmental liabilities when it is probable a liability has been incurred and the amount of the liability is reasonably estimable. Reserves for environmental liabilities totaled $8 million and $8 million at December 31, 2018 and September 30, 2018, respectively. Adient reviews the status of its environmental sites on a quarterly basis and adjusts its reserves accordingly. Such potential liabilities accrued by Adient do not take into consideration possible recoveries of future insurance proceeds. They do, however, take into account the likely share other parties will bear at remediation sites. It is difficult to estimate Adient's ultimate level of liability at many remediation sites due to the large number of other parties that may be involved, the complexity of determining the relative liability among those parties, the uncertainty as to the nature and scope of the investigations and remediation to be conducted, the uncertainty in the application of law and risk assessment, the various choices and costs associated with diverse technologies that may be used in corrective actions at the sites, and the often quite lengthy periods over which eventual remediation may occur. Nevertheless, Adient does not currently believe that any claims, penalties or costs in connection with known environmental matters will have a material adverse effect on Adient's financial position, results of operations or cash flows.

Adient is involved in various lawsuits, claims and proceedings incident to the operation of its businesses, including those pertaining to product liability, casualty environmental, safety and health, intellectual property, employment, commercial and contractual matters, and various other matters. Although the outcome of any such lawsuit, claim or proceeding cannot be predicted with certainty and some may be disposed of unfavorably to Adient, it is management's opinion that none of these will have a material adverse effect on Adient's financial position, results of operations or cash flows. Costs related to such matters were not material to the periods presented.

Financial Results Summary

Significant aspects of Adient's financial results for the first quarter of fiscal 2019 include the following:

• Adient recorded net sales of $4,158 million for the first quarter of fiscal 2019, representing a decrease of $46 million when compared to the first quarter of fiscal 2018. The decrease in net sales is primarily due to the unfavorable foreign currency impact and lower volumes in Europe and China, partially offset by higher volumes in North America and Asia.

• Gross profit was $180 million, or 4.3% of net sales for the first quarter of fiscal 2019 compared to $201 million, or 4.8% of net sales for the first quarter of fiscal 2018. Profitability, including gross profit as a percentage of net sales, was lower primarily due to ongoing business performance issues in Seating.

• Equity income was $83 million for the first quarter of fiscal 2019, which compares to equity income of $96 million for the first quarter of fiscal 2018. The decrease was primarily attributable to overall lower profitability within certain Seating affiliates and ongoing operating performance issues at YFAI.

• Net loss attributable to Adient was $17 million for the first quarter of fiscal 2019, compared to $216 million of net loss attributable to Adient for the first quarter of fiscal 2018. The year over year decrease in net loss attributable to Adient is primarily attributable to a prior year tax charge related to the impact of the 2018 U.S. tax reform legislation offset by lower profitability within Seating.

Net Sales

	Three Months Ended December 31,
(in millions)	2018		Change	2017
Net sales	$	4,158	-1%	$	4,204

Net sales decreased by $46 million, or 1%, in the first quarter of fiscal 2019 as compared to the first quarter of fiscal 2018 primarily due to the unfavorable foreign currency impact of $94 million and lower volumes in Europe and China, partially offset by higher volumes in North America and Asia. Refer to the segment analysis below for a discussion of segment net sales.

Cost of Sales / Gross Profit

	Three Months Ended December 31,

Cost of sales	$	3,978		-1%	$	4,003
Gross profit	$	180		-10%	$	201

Cost of sales decreased by $25 million, or 1%, and gross profit decreased by $21 million, or 10%, in the first quarter of fiscal 2019 as compared to the first quarter of fiscal 2018. Cost of sales was impacted favorably by the impact of foreign currency ($84 million), a reduction in depreciation expense ($25 million) and prior year Becoming Adient charges, partially offset by volume decreases and continued business performance issues related to launch inefficiencies within Seating, including higher freight and higher operational waste. These ongoing performance issues also resulted in a year-over-year decline of gross profit as a percentage of net sales. Refer to the segment analysis below for a discussion of segment profitability.

Selling, general and administrative expenses (SG&A) decreased by $18 million in the first quarter of fiscal 2019 as compared to the first quarter of fiscal 2018. SG&A was favorably impacted by lower engineering costs ($21 million), lower depreciation expense ($6 million) and a favorable impact of foreign currency ($4 million), partially offset by reestablishing certain discretionary spending, primarily incentive compensation, in the current year. Refer to the segment analysis below for a discussion of segment profitability.

Equity income was $83 million for the first quarter of fiscal 2019, which is $13 million lower compared to the first quarter of fiscal 2018.

Income Tax Provision

	Three Months Ended December 31,
(in millions)	2018		Change	2017
Income tax provision (benefit)	$	10	-96%	$	265

The first quarter fiscal 2019 income tax expense of $10 million was higher than the statutory rate of 12.5% primarily due to the impact of recognizing no tax benefit for losses in jurisdictions with valuation allowances, partially offset by a tax rate change at a consolidated affiliate in China. The year over year decrease in income tax expense is primarily attributable to the prior year tax charge of $258 million related to the impact of the 2018 U.S. tax reform legislation.

Income Attributable to Noncontrolling Interests

Income (loss) attributable to noncontrolling interests	$	28	40%	$	20

The increase in income attributable to noncontrolling interests for the first quarter of fiscal 2019 when compared to the same period in the prior year was primarily attributable to higher income resulting from higher volumes at certain Seating affiliates in varying jurisdictions.

Net Income (Loss) Attributable to Adient

	Three Months Ended December 31,

Net income (loss) attributable to Adient	$	(17	)	-92%	$	(216	)

Net loss attributable to Adient was $(17) million for the first quarter of fiscal 2019 compared to $(216) million of net loss attributable to Adient for the first quarter of fiscal 2018. The year over year decrease in net loss attributable to Adient is primarily attributable to a prior year tax charge ($258 million) related to the impact of the 2018 U.S. tax reform legislation, offset by lower profitability within Seating and lower levels of equity income.

Comprehensive loss attributable to Adient was $4 million for the first quarter of fiscal 2019 compared to comprehensive loss attributable to Adient for the first quarter of fiscal 2018 of $155 million. The decrease in comprehensive loss attributable to Adient for the first quarter of fiscal 2019 was primarily due to reduced net losses attributable to Adient ($199 million) partially offset by unfavorable year-over-year impact of foreign currency ($55 million). The year-over-year unfavorable foreign currency impact was primarily driven by the weakening of the Chinese yuan against the U.S. dollar.

Segment Analysis

Adient evaluates the performance of its reportable segments using an adjusted EBITDA metric defined as income before income taxes and noncontrolling interests, excluding net financing charges, qualified restructuring and impairment costs, restructuring related-costs, incremental "Becoming Adient" costs, separation costs, net mark-to-market adjustments on pension and postretirement plans, transaction gains/losses, purchase accounting amortization, depreciation, stock-based compensation and other non-recurring items ("Adjusted EBITDA"). Also, certain corporate-related costs are not allocated to the segments. The reportable segments are consistent with how management views the markets served by Adient and reflect the financial information that is reviewed by its chief operating decision maker. Adient has three reportable segments for financial reporting purposes:

• Seating: This segment produces complete seat systems for automotive and other mobility applications, as well as certain components of complete seat systems, such as foam, trim and fabric.

• Seat Structures & Mechanisms (SS&M): This segment produces seat structures and mechanisms for inclusion in complete seat systems that are produced by Adient or others.

• Interiors: This segment, derived from Adient's global automotive interiors joint ventures, produces instrument panels, floor consoles, door panels, overhead consoles, cockpit systems, decorative trim and other products.

(1) The presentation of certain amounts has been revised from what was previously reported to retrospectively adopt Accounting Standard Update ("ASU") 2017-07, "Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Cost" as of October 1, 2018. See Note 1, "Basis of Presentation and Summary of Significant Accounting Policies," for more information.

(2) Corporate-related costs not allocated to the segments include executive office, aviation, communications, corporate development, legal, finance and marketing.

(3) Reflects incremental expenses associated with becoming an independent company. Includes non-cash costs of $6 million in the three months ended December 31, 2017.

(4) Reflects qualified restructuring charges for costs that are directly attributable to restructuring activities and meet the definition of restructuring under ASC 420 and non-recurring impairment charges.

(5) Reflects amortization of intangible assets including those related to partially owned affiliates recorded within equity income. As a result of the fiscal year 2018 YFAI impairment, the intangible assets related to YFAI were deemed to be fully impaired and thus no longer amortized.

(7) For the three months ended December 31, 2017, stock based compensation excludes $6 million which is included in Becoming Adient costs, discussed above.

(8) For the three months ended December 31, 2017, depreciation excludes $2 million which is included in restructuring related charges, discussed above.

(in millions)	2018		Change	2017
Net sales	$	3,739	-2%	$	3,796
Adjusted EBITDA	$	261	-26%	$	354

Net sales decreased during the first quarter of fiscal 2019 by $57 million due to the unfavorable impact of foreign currency ($76 million) and net pricing reductions ($14 million), partially offset by overall higher volumes ($33 million). The volume increase related to higher sales in North America and Asia, partially offset by lower sales in Europe and China.

Adjusted EBITDA decreased during the first quarter of fiscal 2019 by $93 million due to an increase in operating costs related to launch inefficiencies, including increased freight and operational waste ($72 million), impact of net pricing reductions ($14 million), higher administration and engineering costs ($10 million), the unfavorable impact of foreign currency ($8 million) and lower equity income ($6 million), partially offset by lower net material costs ($14 million) and higher volumes in certain regions ($3 million).

Net sales increased during the first quarter of fiscal 2019 by $9 million due to higher volumes ($25 million) and certain material economic recoveries($10 million), partially offset by the unfavorable impact of foreign currency ($18 million) and net pricing reductions ($8 million). The volume increase was attributable to North America, partially offset by decreases in Europe.

Adjusted EBITDA losses declined during the first quarter of fiscal 2019 by $10 million due to the impact of improved business performance, including lower launch related costs and reduced freight ($27 million) and lower administrative expenses ($1 million), partially offset by net pricing reductions ($8 million), impact of product mix ($6 million), lower equity income ($2 million) and the unfavorable impact of foreign currency ($2 million).

Adjusted EBITDA decreased during the first quarter of fiscal 2019 by $14 million, primarily attributable to lower volumes in China and North America and ongoing operational issues at YFAI ($13 million) and the unfavorable impact of foreign currency ($1 million).

Liquidity and Capital Resources

Adient's primary liquidity needs are to fund general business requirements, including working capital, capital expenditures, restructuring costs and debt service requirements. Adient's principal sources of liquidity are the revolving credit facility and other debt issuances, and existing cash balances. Funding also previously came from the former Parent through October 31, 2016 and as part of the separation agreement. Adient actively manages its working capital and associated cash requirements and continually seeks more effective uses of cash. Working capital is highly influenced by the timing of cash flows associated with sales and purchases, and therefore can be difficult to manage at times. Adient had cash and cash equivalents of $406 million and $687 million as of December 31, 2018 and September 30, 2018, respectively. Adient's revolving credit facility provides for $1.5 billion of commitments and was undrawn at December 31, 2018 and September 30, 2018. See below and refer to Note 7, "Debt and Financing

Adient plc | Form 10-Q | 36

Arrangements," of the notes to consolidated financial statements for discussion of financing arrangements. Following the first quarter of fiscal 2019 dividend payout, Adient has suspended future dividends.

Indebtedness

The Original Credit Facilities include commitments for a $1.5 billion revolving credit facility (undrawn at December 31, 2018 and September 30, 2018) and a $1.5 billion Term Loan A facility (which was fully drawn during the fourth quarter of fiscal 2016). The Original Credit Facilities mature in July 2021. Until the Term Loan A maturity date, amortization of the funded Term Loan A is required in an amount per quarter equal to 1.25% of the original principal amount prior to July 27, 2019 and 2.5% in each quarter thereafter prior to final maturity. The Term Loan A facility also requires mandatory prepayments in connection with certain non-ordinary course asset sales and insurance recovery and condemnation events, among other things, and subject in each case to certain significant exceptions.

During the first quarter of fiscal 2019, Adient entered into an amendment to the Original Credit Facilities (“First Amended Credit Facilities") whereby the financial maintenance covenant was amended to require Adient to maintain a total net leverage ratio equal to or less than 4.5x adjusted EBITDA, with step down provisions starting in the quarter ending December 31, 2020. The amendment also expanded the upper range of interest rate margins such that the drawn portion of the First Amended Credit Facilities will bear interest based on LIBOR plus a margin between 1.25% - 2.50% (previously 1.25% - 2.25%), based on Adient’s total net leverage ratio. No other terms were impacted by the amendment. During the second quarter of fiscal 2019, Adient entered into an amendment to the First Amended Credit Facilities (“Second Amended Credit Facilities") whereby the financial maintenance covenant contained in the First Amended Credit Facilities was amended to require Adient to maintain a first lien secured net leverage ratio equal to or less than 2.5x adjusted EBITDA as of the last day of each quarter, with step down provisions starting on September 30, 2020. The amendment also added a new tier to the pricing schedule that will be applicable when the total net leverage ratio exceeds 4.0x adjusted EBITDA and amended certain other definitions, negative covenants and other terms within the credit facility. Adient expects to be in compliance with its financial covenants for the foreseeable future.

Adient is currently exploring financing options that would provide further flexibility for its business including the refinancing of its credit facilities.

Sources of Cash Flows

	Three Months Ended December 31,
(in millions)	2018			2017
Cash provided (used) by operating activities	$	(128	)	$	(127	)
Cash provided (used) by investing activities	(118		)	(146		)
Cash provided (used) by financing activities	(38		)	(49		)
Capital expenditures	(144		)	(143		)

Operating Cash Flows: Cash flows from operating activities remained consistent year over year with higher net income and overall favorable changes to working capital offset by changes in deferred income taxes.

Investing Cash Flows: The decrease in cash used by investing activities is primarily attributable to the sale of both the Detroit, Michigan properties and remaining airplane for approximately $35 million, partially offset by loans to affiliates for $11 million.

Financing Cash Flows: The decrease in cash used by financing activities is primarily attributable to Adient's JV partner’s contribution of $28 million as part of the formation of a consolidated joint venture, partially offset by higher amounts of dividends paid to non-controlling interests.

Capital expenditures: Capital expenditures remained consistent year over year based on similar levels of program spend on product launches.

The decrease in working capital of $124 million is primarily attributable to lower levels of cash and accounts receivable as of December 31, 2018 offset by lower levels of accounts payable.

Restructuring and Impairment Costs

Adient committed to a restructuring plan in fiscal 2019 to drive cost efficiencies and to balance our global production against demand and recorded $25 million of restructuring costs in the consolidated statement of income. The restructuring actions related to cost reduction initiatives in the Seating and SS&M segments. The costs consist primarily of workforce reductions and plant closures. The restructuring actions are expected to be substantially complete in fiscal 2019. The restructuring plan reserve balance of $23 million at December 31, 2018 is expected to be paid in cash.

Adient committed to a restructuring plan in fiscal 2018 to drive cost efficiencies and to balance our global production against demand and recorded $43 million of restructuring costs in the consolidated statement of income that was offset by underspend in prior years by $27 million. The restructuring actions related to cost reduction initiatives in the Seating and SS&M segments. The costs consist primarily of workforce reductions and plant closures. Adient currently estimates that upon completion of the restructuring actions, the fiscal 2018 restructuring plan will reduce annual operating costs by approximately $65 million, which is primarily the result of lower costs of sales and selling, general and administrative expenses due to reduced employee-related costs, of which approximately 55% will result in net savings. The restructuring actions are expected to be substantially complete in fiscal 2019. The restructuring plan reserve balance of $38 million at December 31, 2018 is expected to be paid in cash.

Adient committed to a restructuring plan in fiscal 2017 to drive cost efficiencies and to balance our global production against demand and recorded $46 million of restructuring and impairment costs in the consolidated statement of income. The restructuring actions related to cost reduction initiatives in the Seating segment. The costs consist primarily of workforce reductions and plant closures. Adient currently estimates that upon completion of the restructuring actions, the fiscal 2017 restructuring plan will reduce annual operating costs by approximately $40 million, which is primarily the result of lower cost of sales and selling, general and administrative expenses due to reduced employee-related costs, of which approximately 55%-60% will result in net savings. Adient partially achieved these savings in fiscal years 2017 and 2018. The restructuring actions are expected to be substantially complete in fiscal 2019. The restructuring plan reserve balance of $11 million at December 31, 2018 is expected to be paid in cash.

Adient committed to a restructuring plan in fiscal 2016 (the "2016 Plan") to drive cost efficiencies and to balance our global production against demand and recorded $332 million of restructuring and impairment costs in the consolidated statement of income. The restructuring actions related to cost reduction initiatives primarily in the Seating and SS&M segments. The costs consist primarily of workforce reductions, plant closures and asset impairments. Adient currently estimates that upon completion of the restructuring actions, the fiscal 2016 restructuring plan will reduce annual operating costs by approximately $150 million, which is primarily the result of lower cost of sales and selling, general and administrative expenses due to reduced employee-related costs and depreciation expense, of which approximately 70%-75% will result in net savings. Adient partially achieved these savings in fiscal years 2016 through 2018, with the full benefit expected in fiscal 2019. The restructuring actions are expected to be substantially complete in fiscal 2021. The restructuring plan reserve balance of $73 million at December 31, 2018 is expected to be paid in cash.

Since the announcement of the 2016 Plan in fiscal 2016, Adient has experienced lower employee severance and termination benefit cash payouts than previously calculated of approximately $20 million, due to changes in cost reduction actions. The planned workforce reductions disclosed for the 2016 Plan have been updated for Adient's revised actions.

Off-Balance Sheet Arrangements and Contractual Obligations

There have been no material changes to the off-balance sheet arrangements and contractual obligations disclosed in Adient's Annual Report on Form 10-K for the year ended September 30, 2018.

Adient plc | Form 10-Q | 38

Effects of Inflation and Changing Prices

The effects of inflation have not been significant to Adient's results of operations in recent years. Generally, Adient has been able to implement operating efficiencies to sufficiently offset cost increases, which have been moderate.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, Adient's principal executive officer and principal financial officer evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934 (the "Exchange Act")), which are designed to provide reasonable assurance that we are able to record, process, summarize and report the information required to be disclosed in our reports under the Exchange Act within the time periods specified in SEC rules and forms. Based on their evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed in reports that we file or submit under the Exchange Act is accumulated and communicated to management, and made known to our principal executive officer and principal financial officer, on a timely basis to ensure that it is recorded, processed, summarized and reported within the time period specified in the SEC's rules and forms.

Changes in Internal Control over Financial Reporting

There were no changes in internal control over financial reporting during the three months ended December 31, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

Adient is involved in various lawsuits, claims and proceedings incident to the operation of its businesses, including those pertaining to product liability, product safety, environmental, safety and health, intellectual property, employment, commercial and contractual matters and various other matters.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies

1. Basis of Presentation and Summary of Significant Accounting Policies

Adient is a global leader in the automotive seating supplier industry. Adient has a leading market position in the Americas, Europe and China, and has longstanding relationships with the largest global original equipment manufacturers, or OEMs, in the automotive space. Adient's proprietary technologies extend into virtually every area of automotive seating solutions, including complete seating systems, frames, mechanisms, foam, head restraints, armrests, trim covers and fabrics. Adient is an independent seat supplier with global scale and the capability to design, develop, engineer, manufacture, and deliver complete seat systems and components in every major automotive producing region in the world. Adient also participates in the automotive interiors market primarily through its global automotive interiors joint venture in China, Yanfeng Global Automotive Interior Systems Co., Ltd., or YFAI.

Basis of Presentation

The unaudited consolidated financial statements of Adient have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. These interim consolidated financial statements include all adjustments (consisting of normal recurring adjustments, except as otherwise disclosed) that management believes are necessary for a fair statement of the results of operations, financial position and cash flows of Adient for the interim periods presented. Interim results are not necessarily indicative of full-year results.

Principles of Consolidations

Adient consolidates its wholly-owned subsidiaries and those entities in which it has a controlling interest. Investments in partially-owned affiliates are accounted for by the equity method when Adient's interest exceeds 20% and does not have a controlling interest.

Consolidated VIEs

Based upon the criteria set forth in the Financial Accounting Standards Board (the FASB) Accounting Standards Codification (ASC) 810, "Consolidation," Adient has determined that it was the primary beneficiary in two variable interest entities (VIEs) for the reporting periods ended December 31, 2018 and September 30, 2018, respectively, as Adient absorbs significant economics of the entities and has the power to direct the activities that are considered most significant to the entities.

The two VIEs manufacture seating products in North America for the automotive industry. Adient funds the entities' short-term liquidity needs through revolving credit facilities and has the power to direct the activities that are considered most significant to the entities through its key customer supply relationships.

The carrying amounts and classification of assets (none of which are restricted) and liabilities included in Adient's consolidated statements of financial position for the consolidated VIEs are as follows:

	December 31,		September 30,
(in millions)	2018		2018
Current assets	$	221	$	270
Noncurrent assets	42		43
Total assets	$	263	$	313
Current liabilities	$	197	$	252
Total liabilities	$	197	$	252

Earnings Per Share

The following table shows the computation of basic and diluted earnings per share:

	Three Months Ended December 31,
(in millions, except per share data)	2018			2017
Numerator:
Net income (loss) attributable to Adient	$	(17	)	$	(216	)
Denominator:
Shares outstanding	93.5			93.2
Effect of dilutive securities	—			—
Diluted shares	93.5			93.2
Earnings per share:
Basic	$	(0.18	)	$	(2.32	)
Diluted	$	(0.18	)	$	(2.32	)

Potentially dilutive securities whose effect would have been antidilutive are excluded from the computation of diluted earnings per share. The impact of excluding antidilutive securities was insignificant for all periods presented.

New Accounting Pronouncements

Standards Adopted During Fiscal 2019

ASU 2014-09, Revenue - Revenue from Contracts with Customers. On October 1, 2018, Adient adopted Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("ASC 606"), and all the related amendments using the modified retrospective method as applied to all customer contracts that were not completed as of October 1, 2018. As a result, financial information for reporting periods beginning on or after October 1, 2018 are presented in accordance with ASC 606. Comparative financial information for reporting periods beginning prior to October 1, 2018 has not been adjusted and continues to be reported in accordance with Adient's revenue recognition policies prior to the adoption of ASC 606. Adient did not record a cumulative adjustment related to the adoption of ASC 606, and the effects of adoption were not significant. Refer to Note 2, "Revenue Recognition," of the notes to the consolidated financial statements for information related to Adient's adoption of ASU 2014-09.

ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. On October 1, 2018, Adient adopted the amendments to ASU 2017-07 that improve the presentation of net periodic pension and postretirement benefit costs and retrospectively adopted the presentation of service cost separate from the other components of net periodic costs. The interest cost, expected return on assets, amortization of prior service costs, net remeasurement, and other costs have been reclassified from cost of sales and selling, general and administrative expenses to other pension expense (income). Adient elected to apply the practical expedient which allows reclassification of amounts previously disclosed in the retirement benefits note as the basis for applying retrospective presentation for comparative periods as it is impracticable to determine the disaggregation of the cost components for amounts capitalized and amortized in those periods. On a prospective basis, the other components of net periodic benefit costs will not be included in amounts capitalized in inventory or property, plant, and equipment.

The effect of the retrospective presentation change related to the net periodic cost of Adient's defined benefit pension and other postretirement employee benefits ("OPEB") plans on the consolidated statements of income (loss) for the three months ended December 31, 2017 resulted in a $1 million increase to cost of sales, a $1 million decrease to gross profit, a $1 million decrease to earnings (loss) before interest and income taxes and a $1 million increase to other pension expense (income) line items in the condensed consolidated statements of income. As a result of presenting certain pension costs as non-operating items, adjusted EBITDA decreased by $1 million in the Seating segment for the three months ended December 31, 2017.

Adient also adopted the following standards during fiscal 2019, none of which had a material impact to the consolidated financial statements or consolidated financial statement disclosures:

Standard Adopted	Description	Date Effective and Adopted
ASU 2016-01 and ASU 2018-03, Recognition and Measurement of Financial Assets and Financial Liabilities	ASU 2016-01 amends certain aspects of recognition, measurement, presentation and disclosure of financial instruments.	October 1, 2018

ASU 2017-05, Gains and Losses from the Derecognition of Nonfinancial Assets	ASU 2017-05 will follow the same implementation guidelines as ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606).	October 1, 2018
ASU 2017-09, Stock Compensation - Scope of Modification Accounting	ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718.	October 1, 2018
ASU 2018-08, Not for Profit Entities: Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made	ASU 2018-08 is intended to clarify and improve the scope and the accounting guidance for contributions received and contributions made. The amendments in ASU No. 2018-08 should assist entities in (1) evaluating whether transactions should be accounted for as contributions (nonreciprocal transaction) within the scope of Topic 958, Not-for-Profit Entities, or as exchange (reciprocal) transactions subject to other guidance and (2) determining whether a contribution is conditional. This amendment applies to all entities that make or receive grants or contributions.	October 1, 2018
ASU 2018-15, Intangibles-Goodwill and Other-Internal Use Software: Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract	The amendments in ASU 2018-15 require implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance. The amendments also require an entity to disclose the nature of its hosting arrangements and adhere to certain presentation requirements in its balance sheet, income statement and statement of cash flows.	ASU No. 2018-15 is effective for Adient for the quarter ending December 31, 2019, with early adoption permitted. Adient early adopted ASU No. 2018-15 effective October 1, 2018.
ASU 2018-16, Derivatives and Hedging: Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes	The amendments in this Update permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the UST, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the SIFMA Municipal Swap Rate.	October 1, 2018

Standards Effective After Fiscal 2019

Adient believes that the ASU summarized below, which is effective fiscal 2020, could significantly impact the consolidated financial statements:

Standard Pending Adoption	Description	Anticipated Impact	Effective Date
ASU 2016-02, 2018-01, 2018-10 and 2018-11	The standard requires that a lessee recognize on its balance sheet right-of-use assets and corresponding liabilities resulting from leasing transactions, as well as additional financial statement disclosures. Currently, U.S. GAAP only requires balance sheet recognition for leases classified as capital leases. The provisions of this update apply to substantially all leased assets.	Adient is currently evaluating the impact this standard will have on its consolidated financial position, results of operations and cash flows and expects the impact to the consolidated balance sheet to be significant.	October 1, 2019

Adient has considered the ASUs summarized below, effective after fiscal 2019, none of which are expected to significantly impact the consolidated financial statements:

Standard Adopted	Description	Date Effective
ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments	ASU 2016-13 changes the impairment model for financial assets measured at amortized cost, requiring presentation at the net amount expected to be collected. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts. Available-for-sale debt securities with unrealized losses will now be recorded through an allowance for credit losses.	October 1, 2020
ASU 2018-07, Compensation-Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting	ASU 2018-07 expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606.	October 1, 2019
ASU 2018-13, Fair Value Measurement: Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement	The amendments in ASU 2018-13 eliminate, add, and modify certain disclosure requirements for fair value measurements. ASU 2018-13 will be effective for Adient for the quarter ending December 31, 2019, with early adoption permitted for either the entire ASU or only the provisions that eliminate or modify requirements. The amendments with respect to changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty are to be applied prospectively. All other amendments are to be applied retrospectively to all periods presented.	October 1, 2019
ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General: Disclosure Framework - Changes to the Disclosure Requirements for Defned Benefit Plans	The amendments in ASU 2018-14 eliminate, add, and modify certain disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The guidance is to be applied on a retrospective basis to all periods presented.	October 1, 2020
ASU 2018-17, Consolidated: Targeted Improvements to Related Party Guidance for Variable Interest Entities	The amendments in this Update affect reporting entities that are required to determine whether they should consolidate a legal entity under the guidance within the Variable Interest Entities Subsections of Subtopic 810-10, Consolidation-Overall.	October 1, 2019
ASU 2018-18, Collaborative Arrangements: Clarifying the Interaction between Topic 808 and Topic 606	The amendments in this Update make targeted improvements to generally accepted accounting principles (GAAP) for collaborative arrangements as follows: 1) Clarify that certain transactions between collaborative arrangement participant is a customer in the context of a unit of account. In those situations, all the guidance in Topic 606 should be applied, including recognition, measurement, presentation, and disclosure requirements. 2) Add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606 (that is, a distinct good or service) when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of Topic 606. 3) Require that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

2. Revenue Recognition

Adient adopted Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (ASC 606), and all the related amendments using the modified retrospective method as applied to all customer contracts that were not completed as of October 1, 2018. As a result, financial information for reporting periods beginning on or after October 1, 2018 are presented in accordance with ASC 606. Comparative financial information for reporting periods beginning prior to October 1, 2018 has not been adjusted and continues to be reported in accordance with Adient's revenue recognition policies prior to the adoption of ASC 606. Adient did not record a cumulative adjustment related to the adoption of ASC 606 as the effects of adoption were not significant. The majority of Adient's nonconsolidated partially-owned affiliates will adopt ASC 606 on October 1, 2019.

Adient generates revenue through the sale of automotive seating solutions, including complete seating systems and the components of complete seating systems.

In a typical arrangement with the customer, purchase orders are issued for pre-production activities which consist of engineering, design and development, tooling and prototypes for the manufacture and delivery of component parts. Adient has concluded that these activities are not in the scope of ASC 606 and for that reason, there have been no changes to how Adient accounts for reimbursable pre-production costs.

Adient provides production and service parts to its customers under awarded multi-year programs. The duration of a program is generally consistent with the life cycle of a vehicle, however, the program can be canceled at any time without cause by the customer. Programs awarded to Adient to supply parts to its customers do not contain a firm commitment by the customer for volume or price and do not reach the level of a performance obligation until Adient receives either a purchase order and/or a materials release from the customer for a specific number of parts at a specified price, at which point an enforceable contract exists. Sales revenue is generally recognized at the point in time when parts are shipped and control has transferred to the customer, at which point an enforceable right to payment exists. Contracts may provide for annual price reductions over the production life of the awarded program, and prices are adjusted on an ongoing basis to reflect changes in product content/cost and other commercial factors. The amount of revenue recognized reflects the consideration that Adient expects to be entitled to in exchange for such products based on purchase orders, annual price reductions and ongoing price adjustments (some of which are accounted for as variable consideration and subject to being constrained, but which are not expected to significantly change under ASC 606), net of the impact, if any, of consideration paid to the customer.

Adient has elected to continue to include shipping and handling fees billed to customers in revenue, while including costs of shipping and handling in cost of sales. Taxes collected from customers are excluded from revenue and credited directly to obligations to the appropriate government agencies. Payment terms with customers are established based on customary industry and regional practices. Adient has evaluated the terms of its arrangements and determined that they do not contain significant financing components.

Contract assets primarily relate to the right to consideration for work completed, but not billed at the reporting date on contracts with customers. The contracts assets are transferred to receivables when the rights become unconditional. Contract liabilities primarily relate to contracts where advance payments or deposits have been received, but performance obligations have not yet been satisfied and revenue has not been recognized. No significant contract assets or liabilities were identified upon adoption of ASC606 or at December 31, 2018. As described above, the issuance of a purchase order and/or a materials release by the customer represents the point at which an enforceable contract with the customer exists. Therefore, Adient has elected to apply the practical expedient in ASC 606, paragraph 606-10-50-14 and does not disclose information about the remaining performance obligations that have an original expected duration of one year or less.

3. Acquisitions and Divestitures

Acquisitions

Adient's consolidated affiliate, Adient Aerospace, LLC ("Adient Aerospace"), became operational on October 11, 2018 after securing regulatory approvals. Adient's ownership position in Adient Aerospace is 50.01%. Adient Aerospace will develop, manufacture, and sell a portfolio of seating products to airlines and aircraft leasing companies for installation on Boeing and other OEM commercial airplanes, for both production line-fit and retrofit configurations. Adient Aerospace's results are included within the Seating segment. Initial contributions of $28 million were made during the first quarter of fiscal 2019.

Assets Held for Sale

During fiscal 2018, Adient committed to a plan to sell its Detroit, Michigan properties and its airplanes and actively marketed the sale of these assets. As a result, these assets were classified as assets held for sale and were required to be adjusted to the lower of fair value less cost to sell or carrying value. This resulted in an impairment charge of $49 million which was recorded within restructuring and impairment costs on the consolidated statement of income (loss) during fiscal 2018, of which $39 million related to Seating assets and $10 million related to corporate assets. The impairment was measured using third party sales pricing to determine fair values of the assets. The inputs utilized in the analyses are classified as Level 3 inputs within the fair value hierarchy as defined in ASC 820, "Fair Value Measurement." During the fourth quarter of fiscal 2018, one airplane was sold for $36 million. During the first quarter of fiscal 2019, both the Detroit, Michigan properties and remaining airplane were sold for approximately $35 million.

Product Warranties

6. Product Warranties

Adient offers warranties to its customers depending upon the specific product and terms of the customer purchase agreement. A typical warranty program requires that Adient replace defective products within a specified time period from the date of sale. Adient records an estimate for future warranty-related costs based on actual historical return rates and other known factors. Based on analysis of return rates and other factors, Adient's warranty provisions are adjusted as necessary. Adient monitors its warranty activity and adjusts its reserve estimates when it is probable that future warranty costs will be different than those estimates. Adient's product warranty liability is recorded in the consolidated statements of financial position in other current liabilities.

On July 27, 2016, Adient Global Holdings Ltd ("AGH"), a wholly owned subsidiary of Adient, entered into a credit agreement providing for commitments with respect to a $1.5 billion revolving credit facility (undrawn at December 31, 2018 and September 30, 2018, respectively) and a $1.5 billion Term Loan A facility (the "Original Credit Facilities"). The Original Credit Facilities mature in July 2021. Until the Term Loan A maturity date, amortization of the funded Term Loan A is required in an amount per quarter equal to 1.25% of the original principal amount prior to July 27, 2019 and 2.5% in each quarter thereafter prior to final maturity. The Original Credit Facilities contain covenants that include, among other things and subject to certain significant exceptions, restrictions on Adient's ability to declare or pay dividends, make certain payments in respect of the notes, create liens, incur additional indebtedness, make investments, engage in transactions with affiliates, enter into agreements restricting Adient's subsidiaries' ability to pay dividends, dispose of assets and merge or consolidate with any other person. The Term Loan A facility also requires mandatory prepayments in connection with certain non-ordinary course asset sales and insurance recovery and condemnation events, among other things, and subject in each case to certain significant exceptions.

On November 6, 2018, Adient entered into an amendment to the Original Credit Facilities (“First Amended Credit Facilities") whereby the financial maintenance covenant was amended to require Adient to maintain a total net leverage ratio equal to or less than 4.5x adjusted EBITDA (previously 3.5x adjusted EBITDA), with step down provisions starting in the quarter ending December 31, 2020. The amendment also expanded the upper range of interest rate margins such that the drawn portion of the First Amended Credit Facilities will bear interest based on LIBOR plus a margin between 1.25% - 2.50% (previously 1.25% - 2.25%), based on Adient’s total net leverage ratio. No other terms were impacted by the first amendment. On February 6, 2019, Adient entered into an amendment to the First Amended Credit Facilities (“Second Amended Credit Facilities") whereby the financial maintenance covenant contained in the First Amended Credit Facilities was amended to require Adient to maintain a first lien secured net leverage ratio equal to or less than 2.5x adjusted EBITDA as of the last day of each quarter, with step down provisions starting on September 30, 2020. The amendment also added a new tier to the pricing schedule that will be applicable when the total net leverage ratio exceeds 4.0x adjusted EBITDA and amended certain other definitions, negative covenants and other terms within the credit facility.

The full amount of the Term Loan A facility was drawn in the fourth quarter of fiscal 2016. These funds were transferred to the former Parent at the time of the draw and were reflected within net transfers to the former Parent in the consolidated statement of cash flow during the fourth quarter of fiscal 2016. In February 2017, Adient repaid $100 million of the Term Loan A facility. In May 2017, Adient repaid another $200 million of the Term Loan A facility. The total amount repaid was treated as a prepayment of the quarterly mandatory principle amortization for the period between March 2017 and June 2020 resulting in no required principal payment until June 2020.

AGH will pay a commitment fee on the unused portion of the commitments under the revolving credit facility based on the total net leverage ratio of Adient, ranging from 0.15% to 0.45%.

On August 19, 2016, AGH issued $0.9 billion aggregate principal amount of 4.875% USD-denominated unsecured notes due 2026 and €1.0 billion aggregate principal amount of 3.50% unsecured notes due 2024, in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended. The proceeds of the notes were used, together with the Term Loan A facility, to pay a distribution to the former Parent, with the remaining proceeds used for working capital and general corporate purposes.

On May 29, 2017, Adient Germany Ltd. & Co. KG, a wholly owned subsidiary of Adient, borrowed €165 million in an unsecured term loan from the European Investment Bank due in 2022. The loan bears interest at the 6-month EURIBOR rate plus 90 basis points. Loan proceeds were used to repay $200 million of the Term Loan A.

Derivative Instruments and Hedging Activities

8. Derivative Instruments and Hedging Activities

Adient selectively uses derivative instruments to reduce Adient's market risk associated with changes in foreign currency. Under Adient's policy, the use of derivatives is restricted to those intended for hedging purposes; the use of any derivative instrument for speculative purposes is strictly prohibited. A description of each type of derivative utilized to manage Adient's risk is included in the following paragraphs. In addition, refer to Note 9, "Fair Value Measurements," of the notes to consolidated financial statements for information related to the fair value measurements and valuation methods utilized by Adient for each derivative type.

Adient has global operations and participates in the foreign exchange markets to minimize its risk of loss from fluctuations in foreign currency exchange rates. Adient primarily uses foreign currency exchange contracts to hedge certain foreign exchange rate exposures. Adient hedges 70% to 90% of the nominal amount of each of its known foreign exchange transactional exposures. Gains and losses on derivative contracts offset gains and losses on underlying foreign currency exposures. These contracts have been designated as cash flow hedges under ASC 815, "Derivatives and Hedging," and the effective portion of the hedge gains or losses due to changes in fair value are initially recorded as a component of accumulated other comprehensive income (AOCI) and are subsequently reclassified into earnings when the hedged transactions occur and affect earnings. Any ineffective portion of the hedge is reflected in the consolidated statements of income. These contracts were highly effective in hedging the variability in future cash flows attributable to changes in currency exchange rates at December 31, 2018 and September 30, 2018, respectively.

Adient selectively uses equity swaps to reduce market risk associated with certain of its stock-based compensation plans, such as its deferred compensation plans. The equity swaps are recorded at fair value. Changes in fair value of the equity swaps are reflected in the consolidated statements of income within selling, general and administrative expenses.

As of December 31, 2018, the €1.0 billion aggregate principal amount of 3.50% euro-denominated unsecured notes due 2024 was designated as a net investment hedge to selectively hedge portions of Adient's net investment in Europe. The currency effects of Adient's euro-denominated bonds are reflected in AOCI account within shareholders' equity attributable to Adient where they offset gains and losses recorded on Adient's net investment in Europe.

Adient entered into cross-currency interest rate swaps during fiscal 2018 to selectively hedge portions of its net investment in Europe. The currency effects of the cross-currency interest rate swaps are reflected in the AOCI account within shareholders' equity attributable to Adient, where they offset gains and losses recorded on Adient's net investment in Europe. As of December 31, 2018, Adient had two cross-currency interest rate swaps outstanding totaling approximately €160 million designated as net investment hedges in Adient's net investment in Europe.

The following table presents the location and fair values of derivative instruments and other amounts used in hedging activities included in Adient's consolidated statements of financial position:

Adient enters into International Swaps and Derivatives Associations (ISDA) master netting agreements with counterparties that permit the net settlement of amounts owed under the derivative contracts. The master netting agreements generally provide for net settlement of all outstanding contracts with a counterparty in the case of an event of default or a termination event. Adient has not elected to offset the fair value positions of the derivative contracts recorded in the consolidated statements of financial position. Collateral is generally not required of Adient or the counterparties under the master netting agreements. As of both December 31, 2018 and September 30, 2018, no cash collateral was received or pledged under the master netting agreements.

The gross and net amounts of derivative instruments and other amounts used in hedging activities are as follows:

Fair Value Disclosures [Abstract]

Fair Value Measurements

9. Fair Value Measurements

ASC 820, "Fair Value Measurement," defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 also establishes a three-level fair value hierarchy that prioritizes information used in developing assumptions when pricing an asset or liability as follows:

Level 1: Observable inputs such as quoted prices in active markets;

Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and

Level 3: Unobservable inputs where there is little or no market data, which requires the reporting entity to develop its own assumptions.

ASC 820 requires the use of observable market data, when available, in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.

Recurring Fair Value Measurements

The following tables present Adient's fair value hierarchy for those assets and liabilities measured at fair value:

Valuation Methods

Foreign currency exchange derivatives Adient selectively hedges anticipated transactions that are subject to foreign exchange rate risk primarily using foreign currency exchange hedge contracts. The foreign currency exchange derivatives are valued under a market approach using publicized spot and forward prices. Changes in fair value on foreign exchange derivatives accounted for as hedging instruments under ASC 815 are initially recorded as a component of AOCI and are subsequently reclassified into earnings when the hedged transactions occur and affect earnings. These contracts were highly effective in hedging the variability in future cash flows attributable to changes in currency exchange rates at December 31, 2018 and September 30, 2018, respectively. The changes in fair value of foreign currency exchange derivatives not designated as hedging instruments under ASC 815 are recorded in the consolidated statements of income.

Equity swaps Adient selectively uses equity swaps to reduce market risk associated with certain of its stock-based compensation plans, such as its deferred compensation plans. The equity swaps are recorded at fair value. Changes in fair value of the equity swaps are reflected in the consolidated statements of income within selling, general and administrative expenses.

Cross-currency interest rate swaps Adient selectively uses cross-currency interest rate swaps to hedge portions of its net investment in Europe.

The fair value of cash and cash equivalents, accounts receivable, short-term debt and accounts payable approximate their carrying values. The fair value of long-term debt, which was $3.0 billion and $3.3 billion at December 31, 2018 and September 30, 2018, respectively, was determined primarily using market quotes classified as Level 1 inputs within the ASC 820 fair value hierarchy.

Restructuring and Impairment Costs

12. Restructuring and Impairment Costs

To better align its resources with its overall strategies and reduce the cost structure of its global operations to address the softness in certain underlying markets, Adient commits to restructuring plans as necessary.

During the first quarter of fiscal 2019, Adient committed to a restructuring plan ("2019 Plan") of $25 million. Of the restructuring costs recorded, $12 million relates to the SS&M segment and $13 million relates to the Seating segment. The restructuring actions relate to cost reduction initiatives and consist primarily of workforce reductions. The restructuring actions are expected to be substantially completed by fiscal 2019.

The following table summarizes the changes in Adient's 2019 Plan reserve:

(in millions)	Employee Severance and Termination Benefits
Original Reserve	$	25
Utilized—cash	(2		)
Balance at December 31, 2018	$	23

In fiscal 2018, Adient committed to a restructuring plan ("2018 Plan") of $71 million that was offset by $20 million of underspend in the 2016 Plan and $7 million of underspend related to other plan years. Of the restructuring costs recorded, $23 million relates to the SS&M segment and $48 million relates to the Seating segment. This is the total amount expected to be incurred for this restructuring plan. The restructuring actions relate to cost reduction initiatives and consist primarily of workforce reductions. The restructuring actions are expected to be substantially completed by fiscal 2019.

The following table summarizes the changes in Adient's 2018 Plan reserve:

In fiscal 2017, Adient committed to a restructuring plan ("2017 Plan") within the Seating segment and recorded $46 million of restructuring and impairment costs in the consolidated statements of income. This is the total amount expected to be incurred for this restructuring plan. The restructuring actions relate to cost reduction initiatives and consist primarily of workforce reductions and plant closures. The restructuring actions are expected to be substantially complete in fiscal 2019.

The following table summarizes the changes in Adient's 2017 Plan reserve:

(in millions)	Employee Severance and Termination Benefits
Balance at September 30, 2018	$	12
Utilized—cash	(1		)
Balance at December 31, 2018	$	11

In fiscal 2016, Adient committed to a restructuring plan ("2016 Plan") and recorded $332 million of restructuring and impairment costs in the consolidated statements of income. This is the total amount expected to be incurred for this restructuring plan. The restructuring actions relate to cost reduction initiatives and consist primarily of workforce reductions, plant closures and asset impairments. Of the restructuring and impairment costs recorded, $217 million relates to the Seating segment, $98 million relates to the SS&M segment and $17 million relates to the Interiors segment. The asset impairment charge recorded during fiscal 2016 related primarily to information technology assets within the Seating segment that will not be used going forward by Adient. The restructuring actions are expected to be substantially complete in fiscal 2021.

Since the announcement of the 2016 Plan in fiscal 2016, Adient has experienced lower employee severance and termination benefit cash payouts than previously calculated of approximately $20 million, due to changes in cost reduction actions. The planned workforce reductions disclosed for the 2016 Plan have been updated for Adient's revised actions.

The following table summarizes the changes in Adient's 2016 Plan reserve:

(in millions)	Employee Severance and Termination Benefits			Currency Translation		Total
Balance at September 30, 2018	$	71		$	4	$	75
Utilized—cash	(2		)	—		(2		)
Balance at December 31, 2018	$	69		$	4	$	73

Adient's fiscal 2019, 2018, 2017 and 2016 restructuring plans included workforce reductions of approximately 6,800. Restructuring charges associated with employee severance and termination benefits are paid over the severance period granted to each employee or on a lump sum basis in accordance with individual severance agreements. As of December 31, 2018, approximately 4,300 of the employees have been separated from Adient pursuant to the restructuring plans. In addition, the restructuring plans included fourteen plant closures. As of December 31, 2018, nine of the fourteen plants have been closed.

Adient's management closely monitors its overall cost structure and continually analyzes each of its businesses for opportunities to consolidate current operations, improve operating efficiencies and locate facilities in low cost countries in close proximity to customers. This ongoing analysis includes a review of its manufacturing, engineering, purchasing and administrative functions, as well as the overall global footprint for all its businesses. Because of the importance of new vehicle sales by major automotive manufacturers to operations, Adient is affected by the general business conditions in the automotive industry. Future adverse developments in the automotive industry could impact Adient's liquidity position, lead to impairment charges and/or require additional restructuring of its operations.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

13. Income Taxes

In calculating the provision for income taxes, Adient uses an estimate of the annual effective tax rate based upon the facts and circumstances known at each interim period. On a quarterly basis, the actual effective tax rate is adjusted, as appropriate, based on changes in facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter. For the three months ended December 31, 2018, Adient’s effective tax rate was 48%. The effective rate was higher than the statutory rate of 12.5% primarily due to the impact of recognizing no tax benefit for losses in jurisdictions with valuation allowances, partially offset by a tax rate change in China. For the three months ended December 31, 2017, Adient’s effective tax rate was 384%. The effective rate was higher than the statutory rate of 12.5% primarily due to the charge to recognize the impact of the U.S. tax reform legislation and unfavorable foreign exchange.

Valuation Allowances

As a result of the Company's first quarter fiscal 2019 analysis of the realizability of its worldwide deferred tax assets, and after considering tax planning initiatives and other positive and negative evidence, Adient determined that no material changes to valuation allowances were required.

Adient reviews the realizability of its deferred tax assets on a quarterly basis, or whenever events or changes in circumstances indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results of the legal entity or combined group recording the net deferred tax asset are considered, along with any other positive or negative evidence. All of the factors that Adient considers in evaluating whether and when to establish or release all or a portion of the deferred tax asset valuation allowance involve significant judgment.

Since future financial results may differ from previous estimates, periodic adjustments to Adient's valuation allowances may be necessary. If Adient's operating performance continues to be negatively impacted and actual results differ significantly from current or prior estimates, Adient may conclude that it is more likely than not that a material portion of our deferred tax assets will not be realized. As such, it is possible that a change to valuation allowances in certain jurisdictions may result in a material increase to income tax expense during the next twelve months. In addition, the effective tax rate in subsequent periods would also increase.

Uncertain Tax Positions

At December 31, 2018, Adient had gross tax effected unrecognized tax benefits of $283 million. If recognized, $132 million of Adient's unrecognized tax benefits would impact the effective tax rate. Total net accrued interest at December 31, 2018 was approximately $6 million (net of tax benefit). The interest and penalties accrued during the three months ended December 31, 2018 was not material. Adient recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense.

Impacts of Tax Legislation and Change in Statutory Tax Rates

During the first quarter of fiscal 2019, Adient completed its accounting for the Tax Cuts and Jobs Act Base Erosion and Anti-avoidance Tax valuation allowance resulting in no change to the $100 million income tax impact estimated in fiscal 2018.

During the first quarter of fiscal 2019, Guangzhou Adient Automotive Seating Co., Ltd. ("GAAS”) was approved for High and New Tech Enterprise status for the three-year period of 2018 to 2020, thereby reducing their tax rate from 25% to 15%. As a result, a $7 million income tax benefit was recorded on the reduction of deferred tax liabilities and a reduction of 2018 calendar year income taxes.

Other tax legislation was adopted during the quarter in various jurisdictions, which did not have a material impact on Adient’s consolidated financial statements.

Segment Information

14. Segment Information

Adient evaluates the performance of its reportable segments using an adjusted EBITDA metric defined as income before income taxes and noncontrolling interests, excluding net financing charges, qualified restructuring and impairment costs, restructuring related-costs, incremental "Becoming Adient" costs, separation costs, net mark-to-market adjustments on pension and postretirement plans, transaction gains/losses, purchase accounting amortization, depreciation, stock-based compensation and other non-recurring items ("Adjusted EBITDA"). Also, certain corporate-related costs are not allocated to the segments. The reportable segments are consistent with how management views the markets served by Adient and reflect the financial information that is reviewed by its chief operating decision maker. Adient has three reportable segments for financial reporting purposes:

Notes

(1) The presentation of certain amounts has been revised from what was previously reported to retrospectively adopt Accounting Standard Update ("ASU") 2017-07, "Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Cost" as of October 1, 2018. See Note 1, "Basis of Presentation and Summary of Significant Accounting Policies," for more information.

(2) Corporate-related costs not allocated to the segments include executive office, aviation, communications, corporate development, legal, finance and marketing.

(3) Reflects incremental expenses associated with becoming an independent company. Includes non-cash costs of $6 million in the three months ended December 31, 2017.

(4) Reflects qualified restructuring charges for costs that are directly attributable to restructuring activities and meet the definition of restructuring under ASC 420 and non-recurring impairment charges.

(5) Reflects amortization of intangible assets including those related to partially owned affiliates recorded within equity income. As a result of the fiscal year 2018 YFAI impairment, the intangible assets related to YFAI were deemed to be fully impaired and thus no longer amortized.

(6) Reflects restructuring related charges for costs that are directly attributable to restructuring activities, but do not meet the definition of restructuring under ASC 420.

(7) For the three months ended December 31, 2017, stock based compensation excludes $6 million which is included in Becoming Adient costs, discussed above.

(8) For the three months ended December 31, 2017, depreciation excludes $2 million which is included in restructuring related charges, discussed above.

(9) The three months ended December 31, 2018 reflects $1 million of Futuris integration costs. The three months ended December 31, 2017 reflects $6 million of Futuris integration costs and $8 million related to the impact of the U.S. tax reform legislation at YFAI.

Commitments and Contingencies

16. Commitments and Contingencies

Adient accrues for potential environmental liabilities when it is probable a liability has been incurred and the amount of the liability is reasonably estimable. Reserves for environmental liabilities totaled $8 million and $8 million at December 31, 2018 and September 30, 2018, respectively. Adient reviews the status of its environmental sites on a quarterly basis and adjusts its reserves accordingly. Such potential liabilities accrued by Adient do not take into consideration possible recoveries of future insurance proceeds. They do, however, take into account the likely share other parties will bear at remediation sites. It is difficult to estimate Adient's ultimate level of liability at many remediation sites due to the large number of other parties that may be involved, the complexity of determining the relative liability among those parties, the uncertainty as to the nature and scope of the investigations and remediation to be conducted, the uncertainty in the application of law and risk assessment, the various choices and costs associated with diverse technologies that may be used in corrective actions at the sites, and the often quite lengthy periods over which eventual remediation may occur. Nevertheless, Adient does not currently believe that any claims, penalties or costs in connection with known environmental matters will have a material adverse effect on Adient's financial position, results of operations or cash flows.

Adient is involved in various lawsuits, claims and proceedings incident to the operation of its businesses, including those pertaining to product liability, casualty environmental, safety and health, intellectual property, employment, commercial and contractual matters, and various other matters. Although the outcome of any such lawsuit, claim or proceeding cannot be predicted with certainty and some may be disposed of unfavorably to Adient, it is management's opinion that none of these will have a material adverse effect on Adient's financial position, results of operations or cash flows. Costs related to such matters were not material to the periods presented.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The unaudited consolidated financial statements of Adient have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. These interim consolidated financial statements include all adjustments (consisting of normal recurring adjustments, except as otherwise disclosed) that management believes are necessary for a fair statement of the results of operations, financial position and cash flows of Adient for the interim periods presented. Interim results are not necessarily indicative of full-year results.

Principles of Consolidations

Principles of Consolidations

Adient consolidates its wholly-owned subsidiaries and those entities in which it has a controlling interest. Investments in partially-owned affiliates are accounted for by the equity method when Adient's interest exceeds 20% and does not have a controlling interest.

Consolidated VIEs

Consolidated VIEs

Based upon the criteria set forth in the Financial Accounting Standards Board (the FASB) Accounting Standards Codification (ASC) 810, "Consolidation," Adient has determined that it was the primary beneficiary in two variable interest entities (VIEs) for the reporting periods ended December 31, 2018 and September 30, 2018, respectively, as Adient absorbs significant economics of the entities and has the power to direct the activities that are considered most significant to the entities.

New Accounting Pronouncements

Standards Adopted During Fiscal 2019

ASU 2014-09, Revenue - Revenue from Contracts with Customers. On October 1, 2018, Adient adopted Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("ASC 606"), and all the related amendments using the modified retrospective method as applied to all customer contracts that were not completed as of October 1, 2018. As a result, financial information for reporting periods beginning on or after October 1, 2018 are presented in accordance with ASC 606. Comparative financial information for reporting periods beginning prior to October 1, 2018 has not been adjusted and continues to be reported in accordance with Adient's revenue recognition policies prior to the adoption of ASC 606. Adient did not record a cumulative adjustment related to the adoption of ASC 606, and the effects of adoption were not significant. Refer to Note 2, "Revenue Recognition," of the notes to the consolidated financial statements for information related to Adient's adoption of ASU 2014-09.

ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. On October 1, 2018, Adient adopted the amendments to ASU 2017-07 that improve the presentation of net periodic pension and postretirement benefit costs and retrospectively adopted the presentation of service cost separate from the other components of net periodic costs. The interest cost, expected return on assets, amortization of prior service costs, net remeasurement, and other costs have been reclassified from cost of sales and selling, general and administrative expenses to other pension expense (income). Adient elected to apply the practical expedient which allows reclassification of amounts previously disclosed in the retirement benefits note as the basis for applying retrospective presentation for comparative periods as it is impracticable to determine the disaggregation of the cost components for amounts capitalized and amortized in those periods. On a prospective basis, the other components of net periodic benefit costs will not be included in amounts capitalized in inventory or property, plant, and equipment.

The effect of the retrospective presentation change related to the net periodic cost of Adient's defined benefit pension and other postretirement employee benefits ("OPEB") plans on the consolidated statements of income (loss) for the three months ended December 31, 2017 resulted in a $1 million increase to cost of sales, a $1 million decrease to gross profit, a $1 million decrease to earnings (loss) before interest and income taxes and a $1 million increase to other pension expense (income) line items in the condensed consolidated statements of income. As a result of presenting certain pension costs as non-operating items, adjusted EBITDA decreased by $1 million in the Seating segment for the three months ended December 31, 2017.

Adient also adopted the following standards during fiscal 2019, none of which had a material impact to the consolidated financial statements or consolidated financial statement disclosures:

Standard Adopted	Description	Date Effective and Adopted
ASU 2016-01 and ASU 2018-03, Recognition and Measurement of Financial Assets and Financial Liabilities	ASU 2016-01 amends certain aspects of recognition, measurement, presentation and disclosure of financial instruments.	October 1, 2018

ASU 2017-05, Gains and Losses from the Derecognition of Nonfinancial Assets	ASU 2017-05 will follow the same implementation guidelines as ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606).	October 1, 2018
ASU 2017-09, Stock Compensation - Scope of Modification Accounting	ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718.	October 1, 2018
ASU 2018-08, Not for Profit Entities: Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made	ASU 2018-08 is intended to clarify and improve the scope and the accounting guidance for contributions received and contributions made. The amendments in ASU No. 2018-08 should assist entities in (1) evaluating whether transactions should be accounted for as contributions (nonreciprocal transaction) within the scope of Topic 958, Not-for-Profit Entities, or as exchange (reciprocal) transactions subject to other guidance and (2) determining whether a contribution is conditional. This amendment applies to all entities that make or receive grants or contributions.	October 1, 2018
ASU 2018-15, Intangibles-Goodwill and Other-Internal Use Software: Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract	The amendments in ASU 2018-15 require implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance. The amendments also require an entity to disclose the nature of its hosting arrangements and adhere to certain presentation requirements in its balance sheet, income statement and statement of cash flows.	ASU No. 2018-15 is effective for Adient for the quarter ending December 31, 2019, with early adoption permitted. Adient early adopted ASU No. 2018-15 effective October 1, 2018.
ASU 2018-16, Derivatives and Hedging: Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes	The amendments in this Update permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the UST, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate, and the SIFMA Municipal Swap Rate.	October 1, 2018

Standards Effective After Fiscal 2019

Adient believes that the ASU summarized below, which is effective fiscal 2020, could significantly impact the consolidated financial statements:

Standard Pending Adoption	Description	Anticipated Impact	Effective Date
ASU 2016-02, 2018-01, 2018-10 and 2018-11	The standard requires that a lessee recognize on its balance sheet right-of-use assets and corresponding liabilities resulting from leasing transactions, as well as additional financial statement disclosures. Currently, U.S. GAAP only requires balance sheet recognition for leases classified as capital leases. The provisions of this update apply to substantially all leased assets.	Adient is currently evaluating the impact this standard will have on its consolidated financial position, results of operations and cash flows and expects the impact to the consolidated balance sheet to be significant.	October 1, 2019

Adient has considered the ASUs summarized below, effective after fiscal 2019, none of which are expected to significantly impact the consolidated financial statements:

Standard Adopted	Description	Date Effective
ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments	ASU 2016-13 changes the impairment model for financial assets measured at amortized cost, requiring presentation at the net amount expected to be collected. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts. Available-for-sale debt securities with unrealized losses will now be recorded through an allowance for credit losses.	October 1, 2020
ASU 2018-07, Compensation-Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting	ASU 2018-07 expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606.	October 1, 2019
ASU 2018-13, Fair Value Measurement: Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement	The amendments in ASU 2018-13 eliminate, add, and modify certain disclosure requirements for fair value measurements. ASU 2018-13 will be effective for Adient for the quarter ending December 31, 2019, with early adoption permitted for either the entire ASU or only the provisions that eliminate or modify requirements. The amendments with respect to changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty are to be applied prospectively. All other amendments are to be applied retrospectively to all periods presented.	October 1, 2019
ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General: Disclosure Framework - Changes to the Disclosure Requirements for Defned Benefit Plans	The amendments in ASU 2018-14 eliminate, add, and modify certain disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The guidance is to be applied on a retrospective basis to all periods presented.	October 1, 2020
ASU 2018-17, Consolidated: Targeted Improvements to Related Party Guidance for Variable Interest Entities	The amendments in this Update affect reporting entities that are required to determine whether they should consolidate a legal entity under the guidance within the Variable Interest Entities Subsections of Subtopic 810-10, Consolidation-Overall.	October 1, 2019
ASU 2018-18, Collaborative Arrangements: Clarifying the Interaction between Topic 808 and Topic 606	The amendments in this Update make targeted improvements to generally accepted accounting principles (GAAP) for collaborative arrangements as follows: 1) Clarify that certain transactions between collaborative arrangement participant is a customer in the context of a unit of account. In those situations, all the guidance in Topic 606 should be applied, including recognition, measurement, presentation, and disclosure requirements. 2) Add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606 (that is, a distinct good or service) when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of Topic 606. 3) Require that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer.	October 1, 2019

Revenue Recognition

Adient adopted Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (ASC 606), and all the related amendments using the modified retrospective method as applied to all customer contracts that were not completed as of October 1, 2018. As a result, financial information for reporting periods beginning on or after October 1, 2018 are presented in accordance with ASC 606. Comparative financial information for reporting periods beginning prior to October 1, 2018 has not been adjusted and continues to be reported in accordance with Adient's revenue recognition policies prior to the adoption of ASC 606. Adient did not record a cumulative adjustment related to the adoption of ASC 606 as the effects of adoption were not significant. The majority of Adient's nonconsolidated partially-owned affiliates will adopt ASC 606 on October 1, 2019.

Adient generates revenue through the sale of automotive seating solutions, including complete seating systems and the components of complete seating systems.

In a typical arrangement with the customer, purchase orders are issued for pre-production activities which consist of engineering, design and development, tooling and prototypes for the manufacture and delivery of component parts. Adient has concluded that these activities are not in the scope of ASC 606 and for that reason, there have been no changes to how Adient accounts for reimbursable pre-production costs.

Adient provides production and service parts to its customers under awarded multi-year programs. The duration of a program is generally consistent with the life cycle of a vehicle, however, the program can be canceled at any time without cause by the customer. Programs awarded to Adient to supply parts to its customers do not contain a firm commitment by the customer for volume or price and do not reach the level of a performance obligation until Adient receives either a purchase order and/or a materials release from the customer for a specific number of parts at a specified price, at which point an enforceable contract exists. Sales revenue is generally recognized at the point in time when parts are shipped and control has transferred to the customer, at which point an enforceable right to payment exists. Contracts may provide for annual price reductions over the production life of the awarded program, and prices are adjusted on an ongoing basis to reflect changes in product content/cost and other commercial factors. The amount of revenue recognized reflects the consideration that Adient expects to be entitled to in exchange for such products based on purchase orders, annual price reductions and ongoing price adjustments (some of which are accounted for as variable consideration and subject to being constrained, but which are not expected to significantly change under ASC 606), net of the impact, if any, of consideration paid to the customer.

Adient has elected to continue to include shipping and handling fees billed to customers in revenue, while including costs of shipping and handling in cost of sales. Taxes collected from customers are excluded from revenue and credited directly to obligations to the appropriate government agencies. Payment terms with customers are established based on customary industry and regional practices. Adient has evaluated the terms of its arrangements and determined that they do not contain significant financing components.

Contract assets primarily relate to the right to consideration for work completed, but not billed at the reporting date on contracts with customers. The contracts assets are transferred to receivables when the rights become unconditional. Contract liabilities primarily relate to contracts where advance payments or deposits have been received, but performance obligations have not yet been satisfied and revenue has not been recognized. No significant contract assets or liabilities were identified upon adoption of ASC606 or at December 31, 2018. As described above, the issuance of a purchase order and/or a materials release by the customer represents the point at which an enforceable contract with the customer exists. Therefore, Adient has elected to apply the practical expedient in ASC 606, paragraph 606-10-50-14 and does not disclose information about the remaining performance obligations that have an original expected duration of one year or less.

October 1, 2018

Standards Effective After Fiscal 2019

Adient believes that the ASU summarized below, which is effective fiscal 2020, could significantly impact the consolidated financial statements:

Standard Pending Adoption	Description	Anticipated Impact	Effective Date
ASU 2016-02, 2018-01, 2018-10 and 2018-11	The standard requires that a lessee recognize on its balance sheet right-of-use assets and corresponding liabilities resulting from leasing transactions, as well as additional financial statement disclosures. Currently, U.S. GAAP only requires balance sheet recognition for leases classified as capital leases. The provisions of this update apply to substantially all leased assets.	Adient is currently evaluating the impact this standard will have on its consolidated financial position, results of operations and cash flows and expects the impact to the consolidated balance sheet to be significant.	October 1, 2019

Adient has considered the ASUs summarized below, effective after fiscal 2019, none of which are expected to significantly impact the consolidated financial statements:

Standard Adopted	Description	Date Effective
ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments	ASU 2016-13 changes the impairment model for financial assets measured at amortized cost, requiring presentation at the net amount expected to be collected. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts. Available-for-sale debt securities with unrealized losses will now be recorded through an allowance for credit losses.	October 1, 2020
ASU 2018-07, Compensation-Stock Compensation: Improvements to Nonemployee Share-Based Payment Accounting	ASU 2018-07 expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606.	October 1, 2019
ASU 2018-13, Fair Value Measurement: Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement	The amendments in ASU 2018-13 eliminate, add, and modify certain disclosure requirements for fair value measurements. ASU 2018-13 will be effective for Adient for the quarter ending December 31, 2019, with early adoption permitted for either the entire ASU or only the provisions that eliminate or modify requirements.

In those situations, all the guidance in Topic 606 should be applied, including recognition, measurement, presentation, and disclosure requirements. 2) Add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606 (that is, a distinct good or service) when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of Topic 606. 3) Require that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer.
