Organization, Consolidation and Presentation of Financial Statements [Abstract]
Financial Statements	Financial Statements The consolidated financial statements include the consolidated accounts of Johnson Controls International plc, a corporation organized under the laws of Ireland, and its subsidiaries (Johnson Controls International plc and all its subsidiaries, hereinafter collectively referred to as the "Company" or "Johnson Controls"). In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (which include normal recurring adjustments) necessary to state fairly the financial position, results of operations and cash flows for the periods presented. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been omitted pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC). These consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended September 30, 2016 filed with the SEC on November 23, 2016, portions of which (including Part I, Item 1. Business and Item 3. Legal Proceedings, and the following items from Part II of the Annual Report: Item 6. Selected Financial Data, Item 7. Management’s Discussion and Analysis, and Item 8. Financial Statements and Supplementary Data) were recast in the Company's Current Report on Form 8-K filed with the SEC on February 23, 2017. The results of operations for the three and nine month periods ended June 30, 2017 are not necessarily indicative of results for the Company’s 2017 fiscal year because of seasonal and other factors. Nature of Operations On September 2, 2016, Johnson Controls, Inc. ("JCI Inc.") and Tyco International plc (“Tyco”) completed their combination pursuant to the Agreement and Plan of Merger (the “Merger Agreement”), dated as of January 24, 2016, as amended by Amendment No. 1, dated as of July 1, 2016, by and among JCI Inc., Tyco and certain other parties named therein, including Jagara Merger Sub LLC, an indirect wholly owned subsidiary of Tyco (“Merger Sub”). Pursuant to the terms of the Merger Agreement, on September 2, 2016, Merger Sub merged with and into JCI Inc., with JCI Inc. being the surviving corporation in the Merger and a wholly owned, indirect subsidiary of Tyco (the “Merger”). Following the Merger, Tyco changed its name to “Johnson Controls International plc.” The Merger changed the jurisdiction of organization from the United States to Ireland. The domicile to Ireland became effective on September 2, 2016. The Merger was accounted for as a reverse acquisition using the acquisition method of accounting in accordance with Accounting Standards Codification ("ASC") 805, "Business Combinations." JCI Inc. was the accounting acquirer for financial reporting purposes. Accordingly, the historical consolidated financial statements of JCI Inc. for periods prior to this transaction are considered to be the historic financial statements of the Company. Refer to Note 3, "Merger Transaction," of the notes to consolidated financial statements for further information. On October 31, 2016, the Company completed the spin-off of its Automotive Experience business by way of the transfer of the Automotive Experience Business from Johnson Controls to Adient plc and the issuance of ordinary shares of Adient directly to holders of Johnson Controls ordinary shares on a pro rata basis. Prior to the open of business on October 31, 2016 , each of the Company's shareholders received one ordinary share of Adient plc for every 10 ordinary shares of Johnson Controls held as of the close of business on October 19, 2016, the record date for the distribution. Company shareholders received cash in lieu of fractional shares of Adient, if any. Following the separation and distribution, Adient plc is now an independent public company trading on the New York Stock Exchange (NYSE) under the symbol "ADNT." The Company did not retain any equity interest in Adient plc. Adient’s historical financial results are reflected in the Company’s consolidated financial statements as a discontinued operation. Refer to Note 5, "Discontinued Operations," of the notes to consolidated financial statements for further information. Principles of Consolidation The consolidated financial statements include the consolidated accounts of Johnson Controls International plc and its subsidiaries that are consolidated in conformity with U.S. GAAP. All significant intercompany transactions have been eliminated. The results of companies acquired or disposed of during the year are included in the consolidated financial statements from the effective date of acquisition or up to the date of disposal. Investments in partially-owned affiliates are accounted for by the equity method when the Company’s interest exceeds 20% and the Company does not have a controlling interest. Under certain criteria as provided for in Financial Accounting Standards Board (FASB) ASC 810, "Consolidation," the Company may consolidate a partially-owned affiliate. To determine whether to consolidate a partially-owned affiliate, the Company first determines if the entity is a variable interest entity (VIE). An entity is considered to be a VIE if it has one of the following characteristics: 1) the entity is thinly capitalized; 2) residual equity holders do not control the entity; 3) equity holders are shielded from economic losses or do not participate fully in the entity’s residual economics; or 4) the entity was established with non-substantive voting rights. If the entity meets one of these characteristics, the Company then determines if it is the primary beneficiary of the VIE. The party with the power to direct activities of the VIE that most significantly impact the VIE’s economic performance and the potential to absorb benefits or losses that could be significant to the VIE is considered the primary beneficiary and consolidates the VIE. If the entity is not considered a VIE, then the Company applies the voting interest model to determine whether or not the Company shall consolidate the partially-owned affiliate. Consolidated VIEs Based upon the criteria set forth in ASC 810, the Company has determined that it was the primary beneficiary in one VIE for the reporting period ended June 30, 2017 and three VIEs for the reporting period ended September 30, 2016 , as the Company absorbs significant economics of the entities and has the power to direct the activities that are considered most significant to the entities. Two of the VIEs manufacture products in North America for the automotive industry. The Company funded the entities’ short-term liquidity needs through revolving credit facilities and had the power to direct the activities that were considered most significant to the entities through its key customer supply relationships. These VIE's were divested as a result of the Adient spin-off in the first quarter of fiscal 2017. In fiscal 2012, a pre-existing VIE accounted for under the equity method was reorganized into three separate investments as a result of the counterparty exercising its option to put its interest to the Company. The Company acquired additional interests in two of the reorganized group entities. The reorganized group entities are considered to be VIEs as the other owner party has been provided decision making rights but does not have equity at risk. The Company is considered the primary beneficiary of one of the entities due to the Company’s power pertaining to decisions over significant activities of the entity. As such, this VIE has been consolidated within the Company’s consolidated statements of financial position. The impact of consolidation of the entity on the Company’s consolidated statements of income for the three and nine month periods ended June 30, 2017 and 2016 was not material. The VIE is named as a co-obligor under a third party debt agreement in the amount of $166 million , maturing in fiscal 2020, under which it could become subject to paying more than its allocated share of the third party debt in the event of bankruptcy of one or more of the other co-obligors. The other co-obligors, all related parties in which the Company is an equity investor, consist of the remaining group entities involved in the reorganization. As part of the overall reorganization transaction, the Company has also provided financial support to the group entities in the form of loans totaling $37 million , which are subordinate to the third party debt agreement. The Company is a significant customer of certain co-obligors, resulting in a remote possibility of loss. Additionally, the Company is subject to a floor guaranty expiring in fiscal 2022; in the event that the other owner party no longer owns any part of the group entities due to sale or transfer, the Company has guaranteed that the proceeds received from the sale or transfer will not be less than $25 million . The Company has partnered with the group entities to design and manufacture battery components for the Power Solutions business. The carrying amounts and classification of assets (none of which are restricted) and liabilities included in the Company’s consolidated statements of financial position for the consolidated VIEs are as follows (in millions): June 30, 2017 September 30, 2016 Current assets $ 2 $ 284 Noncurrent assets 53 98 Total assets $ 55 $ 382 Current liabilities $ 4 $ 230 Noncurrent liabilities 43 29 Total liabilities $ 47 $ 259 The Company did not have a significant variable interest in any other consolidated VIEs for the presented reporting periods. Nonconsolidated VIEs As mentioned previously within the "Consolidated VIEs" section above, in fisca1 2012, a pre-existing VIE was reorganized into three separate investments as a result of the counterparty exercising its option to put its interest to the Company. The reorganized group entities are considered to be VIEs as the other owner party has been provided decision making rights but does not have equity at risk. The Company is not considered to be the primary beneficiary of two of the entities as the Company cannot make key operating decisions considered to be most significant to the VIEs. Therefore, the entities are accounted for under the equity method of accounting as the Company’s interest exceeds 20% and the Company does not have a controlling interest. The Company’s maximum exposure to loss includes the partially-owned affiliate investment balances of $63 million and $59 million at June 30, 2017 and September 30, 2016 respectively, as well as the subordinated loan from the Company, third party debt agreement and floor guaranty mentioned previously within the "Consolidated VIEs" section above. Current liabilities due to the VIEs are not material and represent normal course of business trade payables for all presented periods. The Company did not have a significant variable interest in any other unconsolidated VIEs for the presented reporting periods. Restricted Cash At June 30, 2017 , the Company held restricted cash of approximately $37 million , of which $28 million was recorded within other current assets in the consolidated statements of financial position and $9 million was recorded within other noncurrent assets in the consolidated statements of financial position. These amounts were primarily related to cash restricted for payment of asbestos liabilities. At September 30, 2016 , the Company held restricted cash of approximately $88 million , of which $79 million was recorded within other current assets in the consolidated statements of financial position and $9 million was recorded within other noncurrent assets in the consolidated statements of financial position. These amounts were primarily related to cash held in escrow from business divestitures and cash restricted for payment of asbestos liabilities. Retrospective Changes Certain amounts as of September 30, 2016 have been revised to conform to the current year’s presentation. During the first quarter of fiscal 2017, the Company determined that its Automotive Experience business (Adient) met the criteria to be classified as a discontinued operation, which required retrospective application to financial information for all periods presented. Refer to Note 5, "Discontinued Operations," of the notes to consolidated financial statements for further information regarding the Company's discontinued operations. In the first quarter of fiscal 2017, the Company began evaluating the performance of its business segments primarily on segment earnings before interest, taxes and amortization (EBITA), which represents income from continuing operations before income taxes and noncontrolling interests, excluding general corporate expenses, intangible asset amortization, net financing charges, significant restructuring and impairment costs, and the net mark-to-market adjustments related to pension and postretirement plans. Historical information has been revised to present the comparable periods on a consistent basis. In April 2015, the FASB issued Accounting Standards Update (ASU) No. 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs." ASU No. 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability. During the quarter ended December 31, 2016, the Company adopted ASU No. 2015-03 and applied the change retrospectively to all periods presented. This change did not have an impact to any period presented on the consolidated statements of income. The financial statement impact of this change for the period ending September 30, 2016 was a decrease to noncurrent assets held for sale of $44 million , a decrease to noncurrent liabilities held for sale of $44 million , a decrease to other noncurrent assets of $30 million and a decrease to long-term debt of $30 million .

New Accounting Standards

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Standards	New Accounting Standards Recently Adopted Accounting Pronouncements In October 2016, the FASB issued ASU No. 2016-17, "Consolidations (Topic 810): Interests Held through Related Parties that are under Common Control." The ASU changes how a single decision maker of a VIE that holds indirect interest in the entity through related parties that are under common control determines whether it is the primary beneficiary of the VIE. The new guidance amends ASU 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis" issued in February 2015. ASU No. 2016-17 was effective for the Company for the quarter ending December 31, 2016. The adoption of this guidance did not have an impact on the Company's consolidated financial statements. In May 2015, the FASB issued ASU No. 2015-07, "Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)." ASU No. 2015-07 removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. Such investments should be disclosed separate from the fair value hierarchy. ASU No. 2015-07 was effective retrospectively for the Company for the quarter ending December 31, 2016. The adoption of this guidance did not have an impact on the Company's consolidated financial statements, but did impact pension asset disclosures. In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis." ASU No. 2015-02 amends the analysis performed to determine whether a reporting entity should consolidate certain types of legal entities. ASU No. 2015-02 was effective retrospectively for the Company for the quarter ending December 31, 2016. The adoption of this guidance did not have an impact on the Company's consolidated financial statements. Recently Issued Accounting Pronouncements In May 2017, the FASB issued ASU No. 2017-09, "Compensation — Stock Compensation (Topic 718): Scope of Modification Accounting." The ASU provides guidance about which changes to the terms or conditions of a share-based payment award require a reporting entity to apply modification accounting. ASU No. 2017-09 will be effective prospectively for the Company for the quarter ending December 31, 2018, with early adoption permitted. The impact of this guidance for the Company is dependent on any future share-based payment award changes, should they occur. In March 2017, the FASB issued ASU No. 2017-07, "Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." The ASU requires the service cost component of net periodic benefit cost to be presented with other compensation costs. The other components of net periodic benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. The ASU also allows only the service cost component of net periodic benefit cost to be eligible for capitalization. The guidance will be effective for the Company for the quarter ending December 31, 2018. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. The guidance will be effective retrospectively except for the capitalization of the service cost component which should be applied prospectively. The adoption of this guidance is not expected to have a significant impact on the Company's consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, "Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (Step 2) from the goodwill impairment test. Instead, an impairment charge will equal the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the amount of goodwill allocated to the reporting unit. The guidance will be effective prospectively for the Company for the quarter ending December 31, 2020, with early adoption permitted after January 1, 2017. The impact of this guidance for the Company will depend on the outcomes of future goodwill impairment tests. In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)." The ASU requires amounts generally described as restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The guidance will be effective for the Company for the quarter ending December 31, 2018, with early adoption permitted. The amendments in this update should be applied retrospectively to all periods presented. The impact of this guidance for the Company will depend on the levels of restricted cash balances in the periods presented. In October 2016, the FASB issued ASU No. 2016-16, "Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory." The ASU requires the tax effects of all intra-entity sales of assets other than inventory to be recognized in the period in which the transaction occurs. The guidance will be effective for the Company for the quarter ending December 31, 2018, with early adoption permitted but only in the first interim period of a fiscal year. The changes are required to be applied by means of a cumulative-effect adjustment recorded in retained earnings as of the beginning of the fiscal year of adoption. The Company is currently assessing the impact adoption of this guidance will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments." ASU No. 2016-15 provides clarification guidance on eight specific cash flow presentation issues in order to reduce the diversity in practice. ASU No. 2016-15 will be effective for the Company for the quarter ending December 31, 2018, with early adoption permitted. The guidance should be applied retrospectively to all periods presented, unless deemed impracticable, in which case prospective application is permitted. The Company is currently assessing the impact adoption of this guidance will have on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." ASU No. 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. ASU No. 2016-13 will be effective for the Company for the quarter ended December 31, 2020, with early adoption permitted for the quarter ended December 31, 2019. The adoption of this guidance is not expected to have a significant impact on the Company's consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." ASU No. 2016-09 impacts certain aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statements of cash flows. ASU No. 2016-09 will be effective for the Company for the quarter ending December 31, 2017, with early adoption permitted. The Company is currently assessing the impact adoption of this guidance will have on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, "Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting." ASU No. 2016-07 eliminates the requirement for an investment that qualifies for the use of the equity method of accounting as a result of an increase in the level of ownership or degree of influence to adjust the investment, results of operations and retained earnings retrospectively. ASU No. 2016-07 will be effective prospectively for the Company for increases in the level of ownership interest or degree of influence that result in the adoption of the equity method that occur during or after the quarter ending December 31, 2017, with early adoption permitted. The impact of this guidance for the Company is dependent on any future increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." ASU No. 2016-02 requires recognition of operating leases as lease assets and liabilities on the balance sheet, and disclosure of key information about leasing arrangements. ASU No. 2016-02 will be effective retrospectively for the Company for the quarter ending December 31, 2019, with early adoption permitted. The Company is currently assessing the impact adoption of this guidance will have on its consolidated financial statements. The Company has started the assessment process by evaluating the population of leases under the revised definition of what qualifies as a leased asset. The Company is the lessee under various agreements for facilities and equipment that are currently accounted for as operating leases. The new guidance will require the Company to record operating leases on the balance sheet with a right-of-use asset and corresponding liability for future payment obligations. The Company expects the new guidance will have a material impact on its consolidated statements of financial position for the addition of right-of-use assets and lease liabilities, but the Company does not expect it to have a material impact on its consolidated statements of income. In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." ASU No. 2016-01 amends certain aspects of recognition, measurement, presentation and disclosure of financial instruments, including marketable securities. ASU No. 2016-01 will be effective for the Company for the quarter ending December 31, 2018, and early adoption is not permitted, with certain exceptions. The changes are required to be applied by means of a cumulative-effect adjustment on the balance sheet as of the beginning of the fiscal year of adoption. The impact of this guidance for the Company will depend on the magnitude of the unrealized gains and losses on the Company's marketable securities investments. In July 2015, the FASB issued ASU No. 2015-11, "Simplifying the Measurement of Inventory." ASU No. 2015-11 requires inventory that is recorded using the first-in, first-out method to be measured at the lower of cost or net realizable value. ASU No. 2015-11 will be effective prospectively for the Company for the quarter ending December 31, 2017, with early adoption permitted. The adoption of this guidance is not expected to have a significant impact on the Company's consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU No. 2014-09 clarifies the principles for recognizing revenue when an entity either enters into a contract with customers to transfer goods or services or enters into a contract for the transfer of non-financial assets. The original standard was effective retrospectively for the Company for the quarter ending December 31, 2017; however in August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which defers the effective date of ASU No. 2014-09 by one-year for all entities. The new standard will become effective retrospectively for the Company for the quarter ending December 31, 2018, with early adoption permitted, but not before the original effective date. Additionally, in March 2016, the FASB issued ASU No. 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)," in April 2016, the FASB issued ASU No. 2016-10, "Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing," in May 2016, the FASB issued ASU No. 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients," and in December 2016, the FASB issued ASU No. 2016-20, "Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers," all of which provide additional clarification on certain topics addressed in ASU No. 2014-09. ASU No. 2016-08, ASU No. 2016-10, ASU No. 2016-12 and ASU No. 2016-20 follow the same implementation guidelines as ASU No. 2014-09 and ASU No. 2015-14. The Company has elected to adopt the new revenue guidance as of October 1, 2018. In preparation for adoption of the new guidance, the Company has reviewed representative samples of contracts and other forms of agreements with customers globally and is in the process of evaluating the impact of the new revenue standard. Based on its procedures to date, the Company cannot quantify the potential impact the new revenue standard will have to its consolidated financial statements. The Company will decide which retrospective application to apply once its revenue standard assessment is finalized.

Merger Transaction [Abstract]
Merger Transaction [Text Block]	Merger Transaction As discussed in Note 1, "Financial Statements," of the notes to consolidated financial statements, JCI Inc. and Tyco completed the Merger on September 2, 2016. The Merger was accounted for as a reverse acquisition using the acquisition method of accounting in accordance with ASC 805, "Business Combinations." Based on the structure of the Merger and other activities contemplated by the Merger Agreement, relative outstanding share ownership, the composition of the Company's board of directors and the designation of certain senior management positions of the Company, JCI Inc. was the accounting acquirer for financial reporting purposes. Immediately prior to the Merger and in connection therewith, Tyco shareholders received 0.955 ordinary shares of Tyco (which shares are now referred to as shares of the Company, or “Company ordinary shares”) for each Tyco ordinary share they held by virtue of a 0.955 -for-one share consolidation. In the Merger, each outstanding share of common stock, par value $1.00 per share, of JCI Inc. (“JCI Inc. common stock”) (other than shares held by JCI Inc., Tyco and certain of their subsidiaries) was converted into the right to receive either the cash consideration or the share consideration (each as described below), at the election of the holder, subject to proration procedures described in the Merger Agreement and applicable withholding taxes. The election to receive the cash consideration was undersubscribed. As a result, holders of shares of JCI Inc. common stock that elected to receive the share consideration and holders of shares of JCI Inc. common stock that made no election (or failed to properly make an election) became entitled to receive, for each such share of JCI Inc. common stock, $5.7293 in cash, without interest, and 0.8357 Company ordinary shares, subject to applicable withholding taxes. Holders of shares of JCI Inc. common stock that elected to receive the cash consideration became entitled to receive, for each such share of JCI Inc. common stock, $34.88 in cash, without interest, subject to applicable withholding taxes. In the Merger, JCI Inc. shareholders received, in the aggregate, approximately $3.864 billion in cash. Immediately after the closing of, and giving effect to, the Merger, former JCI Inc. shareholders owned approximately 56% of the issued and outstanding Company ordinary shares and former Tyco stockholders owned approximately 44% of the issued and outstanding Company ordinary shares. Tyco is a leading global provider of security products and services, fire detection and suppression products and services, and life safety products. The acquisition of Tyco brings together best-in-class product, technology and service capabilities across controls, fire, security, heating, ventilating and air conditioning (HVAC), power solutions and energy storage, to serve various end-markets including large institutions, commercial buildings, retail, industrial, small business and residential. The combination of the Tyco and JCI Inc. buildings platforms is expected to create immediate opportunities for near-term growth through cross-selling, complementary branch and channel networks, and expanded global reach for established businesses. The new Company is also expected to benefit by combining innovation capabilities and pipelines involving new products, advanced solutions for smart buildings and cities, value-added services driven by advanced data and analytics and connectivity between buildings and energy storage through infrastructure integration. Fair Value of Consideration Transferred The total fair value of consideration transferred was approximately $19.7 billion . Total consideration is comprised of the equity value of the Tyco shares that were outstanding as of September 2, 2016 and the portion of Tyco's share awards and share options earned as of September 2, 2016 ( $224 million ). Share awards and share options not earned ( $101 million ) as of September 2, 2016 will be expensed over the remaining future vesting period. The following table summarizes the total fair value of consideration transferred: (in millions, except for share consolidation ratio and share data) Number of Tyco shares outstanding at September 2, 2016 427,181,743 Tyco share consolidation ratio 0.955 Tyco ordinary shares outstanding following the share consolidation and immediately prior to the Merger 407,958,565 JCI Inc. converted share price (1) $ 47.67 Fair value of equity portion of the Merger consideration $ 19,447 Fair value of Tyco equity awards 224 Total fair value of consideration transferred $ 19,671 (1) Amount equals JCI Inc. closing share price and market capitalization at September 2, 2016 ( $45.45 and $29,012 million , respectively) adjusted for the Tyco $3,864 million cash contribution used to purchase 110.8 million shares of JCI Inc. common stock for $34.88 per share. Fair Value of Assets Acquired and Liabilities Assumed The Company accounted for the Merger with Tyco as a business combination using the acquisition method of accounting. The assets acquired and liabilities assumed were recorded at their preliminary respective fair values as of the acquisition date. As the Company finalizes the fair value of assets acquired and liabilities assumed, additional purchase price adjustments may be recorded during the measurement period in fiscal 2017. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company's results of operations. The finalization of the purchase accounting assessment may result in a change in the valuation of assets acquired and liabilities assumed and may have a material impact on the Company's results of operations and financial position. The preliminary fair values of the assets acquired and liabilities assumed are as follows (in millions): Cash and cash equivalents $ 489 Accounts receivable 2,084 Inventories 815 Other current assets 610 Property, plant, and equipment - net 1,219 Goodwill 16,203 Intangible assets - net 6,304 Other noncurrent assets 536 Total assets acquired $ 28,260 Short-term debt $ 462 Accounts payable 725 Accrued compensation and benefits 312 Other current liabilities 1,444 Long-term debt 6,416 Long-term deferred tax liabilities 847 Long-term pension and postretirement benefits 774 Other noncurrent liabilities 1,436 Total liabilities acquired $ 12,416 Noncontrolling interests 37 Net assets acquired $ 15,807 Cash consideration paid to JCI Inc. shareholders 3,864 Total fair value of consideration transferred $ 19,671 In connection with the Merger, the Company recorded goodwill of $16.2 billion , which is attributable primarily to expected synergies, expanded market opportunities, and other benefits that the Company believes will result from combining its operations with the operations of Tyco. The goodwill created in the Merger is not deductible for tax purposes and is subject to potential significant changes as the purchase price allocation is completed. Goodwill has preliminarily been allocated to the Tyco segment based on how the business was reviewed by the Company's Chief Operating Decision Maker as shown in Note 8, "Goodwill and Other Intangible Assets." In connection with the Tyco Merger, the Company recorded a reduction in goodwill of $160 million in the first nine months of fiscal 2017 related to purchase price allocations. The preliminary purchase price allocation to identifiable intangible assets acquired are as follows: Preliminary Fair Value (in millions) Weighted Average Life (in years) Customer relationships $ 2,280 12 Completed technology 1,580 11 Other definite-lived intangibles 214 7 Indefinite-lived trademarks 2,080 Other indefinite-lived intangibles 90 In-process research and development 60 Total identifiable intangible assets $ 6,304 Acquisitions and Divestitures In the first nine months of fiscal 2017, the Company completed three acquisitions for a combined purchase price, net of cash acquired, of $9 million , $6 million of which was paid in the nine months ended June 30, 2017. The acquisitions in the aggregate were not material to the Company’s consolidated financial statements. In connection with the acquisitions, the Company recorded goodwill of $2 million . In the second quarter of fiscal 2017, the Company announced it signed a definitive agreement to sell its Scott Safety business to 3M Company for approximately $2.0 billion . Net cash proceeds from the transaction are expected to approximate $1.8 to $1.9 billion . Scott Safety is a leader in the design, manufacture and sale of high performance respiratory protection, gas and flame detection, thermal imaging and other critical products for fire services, law enforcement, industrial, oil and gas, chemical, armed forces, and homeland defense end markets. The transaction is expected to close in the first quarter of fiscal 2018, subject to customary closing conditions including required regulatory approval. The Scott Safety business is included in the Tyco segment and is reported within assets and liabilities held for sale in the consolidated statements of financial position as of June 30, 2017. Refer to Note 5, "Discontinued Operations," of the notes to consolidated financial statements for further disclosure related to the Company's net assets held for sale. In the second quarter of fiscal 2017, the Company completed the sale of its ADT security business in South Africa within the Tyco segment. The selling price, net of cash divested, was $129 million , all of which was received in the nine months ended June 30, 2017. In connection with the sale, the Company reduced goodwill in assets held for sale by $92 million . The divestiture was not material to the Company's consolidated financial statements. In the first nine months of fiscal 2017, the Company completed one additional divestiture for a sales price of $4 million , all of which was received in the nine months ended June 30, 2017 . The divestiture decreased the Company's ownership from a controlling to noncontrolling interest, and as a result, the Company deconsolidated cash of $5 million . The divestiture was not material to the Company's consolidated financial statements. In the first nine months of fiscal 2017, the Company received $52 million in net cash proceeds related to prior year business divestitures. In the first quarter of fiscal 2016, the Company formed a joint venture with Hitachi to expand its Building Efficiency product offerings. The Company acquired a 60% ownership interest in the new entity for approximately $208 million ( $638 million purchase price less cash acquired of $430 million ), $133 million of which was paid in the nine months ended June 30, 2016 and $75 million was paid in the nine months ended June 30, 2017. In connection with the acquisition, the Company recorded goodwill of $253 million related to purchase price allocations. In the first nine months of fiscal 2016, the Company completed one additional acquisition for a purchase price, net of cash acquired, of $3 million , none of which was paid as of June 30, 2016. The acquisition was not material to the Company's consolidated financial statements. In connection with the acquisition, the Company recorded goodwill of $4 million . The acquisition increased the Company's ownership from a noncontrolling to controlling interest. As a result, the Company recorded a non-cash gain of $4 million in equity income for the Building Efficiency Rest of World segment to adjust the Company's existing equity investment in the partially-owned affiliate to fair value. In the three months ended June 30, 2016, the Company completed a divestiture for a sales price of $16 million , $14 million of which was received as of June 30, 2016. The divestiture was not material to the Company's consolidated financial statements.

Discontinued Operations [Abstract]
Discontinued Operations	Discontinued Operations As discussed in Note 1, "Financial Statements," of the notes to consolidated financial statements, on October 31, 2016, the Company completed the spin-off of its Automotive Experience business by way of the transfer of the Automotive Experience Business from Johnson Controls to Adient plc. The Company did not retain any equity interest in Adient plc. During the first quarter of fiscal 2017, the Company determined that Adient met the criteria to be classified as a discontinued operation and, as a result, Adient’s historical financial results are reflected in the Company’s consolidated financial statements as a discontinued operation, and assets and liabilities were retrospectively reclassified as assets and liabilities held for sale. The Company did not allocate any general corporate overhead to discontinued operations. The following table summarizes the results of Adient, reclassified as discontinued operations for the nine month period ended June 30, 2017 , and the three and nine month periods ended June 30, 2016 (in millions). As the Adient spin-off occurred on October 31, 2016, there is only one month of Adient results included in the nine month period ended June 30, 2017 . Three Months Ended June 30, Nine Months Ended 2016 2017 2016 Net sales $ 4,362 $ 1,434 $ 12,893 Income from discontinued operations before income taxes 185 1 520 Provision for income taxes on discontinued operations 128 35 1,001 Income from discontinued operations attributable to noncontrolling interests, net of tax 21 9 61 Income (loss) from discontinued operations $ 36 $ (43 ) $ (542 ) For the nine months ended June 30, 2017 , the income from discontinued operations before income taxes included separation costs of $79 million . For the three and nine months ended June 30, 2016 , the income from discontinued operations before income taxes included separation costs of $127 million and $287 million , respectively. For the nine months ended June 30, 2017 , the effective tax rate was more than the U.S. federal statutory rate of 35% primarily due to the tax impacts of separation costs and Adient spin-off related tax expense, partially offset by non-U.S. tax rate differentials.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In calculating the provision for income taxes, the Company 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 upon changed facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter. The U.S. federal statutory tax rate is being used as a comparison since the Company was a U.S. domiciled company for 11 months of 2016 and due to the Company's current legal entity structure. For the three months ended June 30, 2017 , the Company's effective tax rate for continuing operations was 12% . The effective tax rate was lower than the U.S. federal statutory rate of 35% primarily due to the benefits of continuing global tax planning initiatives and non-U.S. tax rate differentials, partially offset by the jurisdictional mix of Tyco Merger transaction and integration costs. For the nine months ended June 30, 2017 , the Company's effective tax rate for continuing operations was 38% . The effective tax rate was higher than the U.S. federal statutory rate of 35% primarily due to the establishment of a deferred tax liability on the outside basis difference of the Company's investment in certain subsidiaries related to the pending divestiture of the Scott Safety business, the jurisdictional mix of significant restructuring and impairment costs, and Tyco Merger transaction /integration costs and purchase accounting impacts, partially offset by the benefits of continuing global tax planning initiatives, non-U.S. tax rate differentials and a tax benefit due to changes in entity tax status. For the three and nine months ended June 30, 2016 , the Company's effective tax rate for continuing operations was 16% and 17% , respectively. The effective rate was lower than the U.S. federal statutory rate of 35% primarily due to the benefits of continuing global tax planning initiatives and non-U.S. tax rate differentials, partially offset by the tax impact of transaction and separation costs. Valuation Allowance The Company 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 consolidated group recording the net deferred tax asset are considered, along with any other positive or negative evidence. Since future financial results may differ from previous estimates, periodic adjustments to the Company’s valuation allowances may be necessary. Uncertain Tax Positions At September 30, 2016 , exclusive of items included in noncurrent liabilities held for sale, the Company had gross tax effected unrecognized tax benefits of $1,706 million , of which $1,604 million , if recognized, would impact the effective tax rate. Total net accrued interest at September 30, 2016 was approximately $55 million (net of tax benefit). The interest and penalties accrued during the nine months ended June 30, 2017 and 2016 were not material. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense. In the U.S., fiscal years 2010 through 2014 are currently under exam by the Internal Revenue Service ("IRS"). Additionally, the Company is currently under exam in the following major non-U.S. jurisdictions: Tax Jurisdiction Tax Years Covered Belgium 2015 - 2016 Brazil 2011 - 2012 Canada 2012 - 2014 France 2010 - 2015 Germany 2007 - 2015 Spain 2010 - 2014 United Kingdom 2011 - 2014 It is reasonably possible that certain tax examinations and/or tax litigation will conclude within the next twelve months, which could be up to a $200 million impact to tax expense. Impacts of Tax Legislation On October 13, 2016, the U.S. Treasury and the IRS released final and temporary Section 385 regulations. These regulations address whether certain instruments between related parties are treated as debt or equity. The Company does not expect that the regulations will have a material impact on its consolidated financial statements. During the nine months ended June 30, 2017 and 2016 , other tax legislation was adopted in various jurisdictions. These law changes did not have a material impact on the Company's consolidated financial statements.

For fiscal 2017, expected volatility is based on historical volatility of certain peer companies over the most recent period corresponding to the expected life as of the grant date. For fiscal 2016, expected volatility is based on the historical volatility of the Company's stock and other factors. The expected dividend yield is based on the expected annual dividend as a percentage of the market value of the Company’s ordinary shares as of the grant date. The Company uses historical data to estimate option exercises and employee terminations within the valuation model. Nine Months Ended 2017 2016 Expected life of option (years) 4.75 & 6.5 6.4 Risk-free interest rate 1.23% - 1.93% 1.64% Expected volatility of the Company’s stock 24.60% 36.00% Expected dividend yield on the Company’s stock 2.21% 2.11% Stock Appreciation Rights (SARs) SARs vest under the same terms and conditions as stock option awards; however, they are settled in cash for the difference between the market price on the date of exercise and the exercise price. As a result, SARs are recorded in the Company’s consolidated statements of financial position as a liability until the date of exercise. The fair value of each SAR award is estimated using a similar method described for stock options. The fair value of each SAR award is recalculated at the end of each reporting period and the liability and expense are adjusted based on the new fair value. Restricted (Nonvested) Stock The Plan provides for the award of restricted stock or restricted stock units to certain employees. These awards are typically share settled unless the employee is a non-U.S. employee or elects to defer settlement until retirement at which point the award would be settled in cash. Restricted awards typically vest after three years from the grant date. The Plan allows for different vesting terms on specific grants with approval by the Board of Directors. The value of restricted awards is based on the closing market value of the Company’s ordinary shares on the date of grant. Performance Share Awards The Plan permits the grant of performance-based share unit ("PSU") awards. The PSUs are generally contingent on the achievement of pre-determined performance goals over a three-year performance period as well as on the award holder's continuous employment until the vesting date. The PSUs are also indexed to the achievement of specified levels of total shareholder return versus a peer group over the performance period. Each PSU that is earned will be settled with shares of the Company's ordinary shares following the completion of the performance period, unless the award holder elected to defer a portion or all of the award until retirement which would then be settled in cash. The fair value of each PSU is estimated on the date of grant using a Monte Carlo simulation that uses the assumptions noted in the following table. The risk-free interest rate for periods during the contractual life of the PSU is based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on historical volatility of certain peer companies over the most recent three-year period as of the grant date. Nine Months Ended Risk-free interest rate 1.40% Expected volatility of the Company’s stock 21.00% Spin-off Modification In connection with the Adient spin-off, pursuant to the Employee Matters Agreement between the Company and Adient, outstanding stock options and SARs held on October 31, 2016 (the “Spin Date”) by employees remaining with the Company were converted into options and SARs of the Company using a 1.085317 -for-one share ratio, which is based on the pre-spin and post-spin closing prices of the Company’s ordinary shares. The exercise prices for options and SARs were converted using the inverse ratio in a manner designed to preserve the intrinsic value of such awards. In addition, pursuant to the Employee Matters Agreement, nonvested restricted stock held on the Spin Date by employees remaining with the Company were converted into nonvested restricted stock of the Company using the 1.085317 -for-one share ratio in a manner designed to preserve the intrinsic value of such awards. There were no performance share awards outstanding as of the Spin Date. Employees remaining with the Company did not receive stock-based compensation awards of Adient as a result of the spin-off. Except for the conversion of awards and related exercise prices discussed herein, the material terms of the awards remained unchanged. No incremental fair value resulted from the conversion of the awards; therefore, no additional compensation expense was recorded related to the award modification. Also in connection with the spin-off transaction, pursuant to the Employee Matters Agreement, employees of Adient were entitled to receive stock-based compensation awards of the Company and Adient in replacement of previously outstanding awards of the Company granted prior to the Spin Date. These awards include stock options, SARs and nonvested restricted stock. Upon the Spin Date, the existing awards held by Adient employees were converted into new awards of the Company and Adient on a pro rata basis and further adjusted based on a formula designed to preserve the intrinsic value of such awards. Additional compensation expense, if any, resulting from the modification of awards held by Adient employees is to be recorded by Adient.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The Company presents both basic and diluted earnings per share (EPS) amounts. Basic EPS is calculated by dividing net income attributable to Johnson Controls by the weighted average number of ordinary shares outstanding during the reporting period. Diluted EPS is calculated by dividing net income attributable to Johnson Controls by the weighted average number of ordinary shares and ordinary equivalent shares outstanding during the reporting period that are calculated using the treasury stock method for stock options, unvested restricted stock and unvested performance share awards. The treasury stock method assumes that the Company uses the proceeds from the exercise of stock option awards to repurchase ordinary shares at the average market price during the period. The assumed proceeds under the treasury stock method include the purchase price that the grantee will pay in the future, compensation cost for future service that the Company has not yet recognized and any windfall tax benefits that would be credited to capital in excess of par value when the award generates a tax deduction. If there would be a shortfall resulting in a charge to capital in excess of par value, such an amount would be a reduction of the proceeds. For unvested restricted stock and unvested performance share awards, assumed proceeds under the treasury stock method would include unamortized compensation cost and windfall tax benefits or shortfalls. The following table reconciles the numerators and denominators used to calculate basic and diluted earnings per share (in millions): Three Months Ended June 30, Nine Months Ended June 30, 2017 2016 2017 2016 Income Available to Ordinary Shareholders Income from continuing operations $ 555 $ 347 $ 779 $ 845 Income (loss) from discontinued operations — 36 (43 ) (542 ) Basic and diluted income available to shareholders $ 555 $ 383 $ 736 $ 303 Weighted Average Shares Outstanding Basic weighted average shares outstanding 935.4 644.9 937.2 647.0 Effect of dilutive securities: Stock options, unvested restricted stock and unvested performance share awards 9.0 4.8 9.6 4.5 Diluted weighted average shares outstanding 944.4 649.7 946.8 651.5 Antidilutive Securities Options to purchase shares 0.1 0.1 0.1 0.2 During the three months ended June 30, 2017 and 2016 , the Company declared a dividend of $0.25 and $0.29 , respectively, per share.

As a result of the spin-off, the Company divested net assets of $4,038 million . As previously disclosed, on October 1, 2015, the Company formed a joint venture with Hitachi. In connection with the acquisition, the Company recorded equity attributable to noncontrolling interests of $679 million . Following the Tyco Merger, the Company adopted, subject to the ongoing existence of sufficient distributable reserves, the existing Tyco International plc $1 billion share repurchase program in September 2016. The share repurchase program does not have an expiration date and may be amended or terminated by the Board of Directors at any time without prior notice. For the three month period ended June 30, 2017 and 2016 , the Company repurchased $307 million and $475 million of its shares, respectively. For the nine month periods ended June 30, 2017 and 2016 , the Company repurchased $426 million and $475 million of its shares, respectively. In April 2017, the Company announced its intention to utilize up to $750 million of the $1 billion authorization during fiscal 2017. Shares may be repurchased from time to time in open market purchases at prevailing market prices, in negotiated transactions off the market, or pursuant to a trading plan in accordance with applicable regulations. The Company consolidates certain subsidiaries in which the noncontrolling interest party has within its control the right to require the Company to redeem all or a portion of its interest in the subsidiary. The redeemable noncontrolling interests are reported at their estimated redemption value. Any adjustment to the redemption value impacts retained earnings but does not impact net income. Redeemable noncontrolling interests which are redeemable only upon future events, the occurrence of which is not currently probable, are recorded at carrying value.

Derivative Instruments and Hedg

Derivative Instruments and Hedging Activities	9 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company selectively uses derivative instruments to reduce market risk associated with changes in foreign currency, commodities, stock-based compensation liabilities and interest rates. Under Company 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 by the Company to manage risk is included in the following paragraphs. In addition, refer to Note 17, "Fair Value Measurements," of the notes to consolidated financial statements for information related to the fair value measurements and valuation methods utilized by the Company for each derivative type. Cash Flow Hedges The Company has global operations and participates in the foreign exchange markets to minimize its risk of loss from fluctuations in foreign currency exchange rates. The Company selectively hedges anticipated transactions that are subject to foreign exchange rate risk primarily using foreign currency exchange hedge contracts. The Company hedges 70% to 90% of the nominal amount of each of its known foreign exchange transactional exposures. As cash flow hedges under ASC 815, "Derivatives and Hedging," the effective portion of the hedge gains or losses due to changes in fair value are initially recorded as a component of 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 during the three and nine months ended June 30, 2017 and 2016 . The Company selectively hedges anticipated transactions that are subject to commodity price risk, primarily using commodity hedge contracts, to minimize overall price risk associated with the Company’s purchases of lead, copper, tin, aluminum and polypropylene in cases where commodity price risk cannot be naturally offset or hedged through supply base fixed price contracts. Commodity risks are systematically managed pursuant to policy guidelines. As cash flow hedges, the effective portion of the hedge gains or losses due to changes in fair value are initially recorded as a component of AOCI and are subsequently reclassified into earnings when the hedged transactions, typically sales, occur and affect earnings. Any ineffective portion of the hedge is reflected in the consolidated statements of income. The maturities of the commodity hedge contracts coincide with the expected purchase of the commodities. These contracts were highly effective in hedging the variability in future cash flows attributable to changes in commodity prices during the three and nine months ended June 30, 2017 and 2016 . The Company had the following outstanding contracts to hedge forecasted commodity purchases: Volume Outstanding as of Commodity Units June 30, 2017 September 30, 2016 Copper Pounds 6,200,000 5,849,000 Polypropylene Pounds 18,000,000 — Lead Metric Tons 8,645 5,185 Aluminum Metric Tons 2,860 2,620 Tin Metric Tons 2,225 185 In September 2005, the Company entered into three forward treasury lock agreements to reduce the market risk associated with changes in interest rates associated with the Company’s anticipated fixed-rate note issuance to finance the acquisition of York International (cash flow hedge). The three forward treasury lock agreements, which had a combined notional amount of $1.3 billion , fixed a portion of the future interest cost for 5-year, 10-year and 30-year notes. The fair value of each treasury lock agreement, or the difference between the treasury lock reference rate and the fixed rate at time of note issuance, is amortized to interest expense over the life of the respective note issuance. In January 2006, in connection with the Company’s debt refinancing, the three forward treasury lock agreements were terminated. Fair Value Hedges The Company selectively uses interest rate swaps to reduce market risk associated with changes in interest rates for its fixed-rate bonds. As fair value hedges, the interest rate swaps and related debt balances are valued under a market approach using publicized swap curves. Changes in the fair value of the swap and hedged portion of the debt are recorded in the consolidated statements of income. In the third quarter of fiscal 2014, the Company entered into four fixed to floating interest rate swaps totaling $400 million to hedge the coupon of its 2.6% notes that matured in December 2016, three fixed to floating interest rate swaps totaling $300 million to hedge the coupon of its 1.4% notes maturing November 2017 and one fixed to floating interest rate swap totaling $150 million to hedge the coupon of its 7.125% notes maturing July 2017. In December 2016, the four remaining outstanding interest rate swaps were terminated. The Company had no interest rate swaps outstanding at June 30, 2017 . There were eight interest rate swaps outstanding as of September 30, 2016 . Net Investment Hedges The Company enters into foreign currency denominated debt obligations to selectively hedge portions of its net investment in non-U.S. subsidiaries. The currency effects of the debt obligations are reflected in the AOCI account within shareholders’ equity attributable to Johnson Controls ordinary shareholders where they offset gains and losses recorded on the Company’s net investments globally. At June 30, 2017 , the Company had one billion euro and 485 million euro bonds designated as net investment hedges in the Company's net investment in Europe. At September 30, 2016 , the Company had 37 billion yen of foreign denominated debt designated as net investment hedge in the Company's net investment in Japan and one billion euro and 500 million euro bonds designated as net investment hedges in the Company's net investment in Europe. Derivatives Not Designated as Hedging Instruments The Company selectively uses equity swaps to reduce market risk associated with certain of its stock-based compensation plans, such as its deferred compensation plans. These equity compensation liabilities increase as the Company’s stock price increases and decrease as the Company’s stock price decreases. In contrast, the value of the swap agreement moves in the opposite direction of these liabilities, allowing the Company to fix a portion of the liabilities at a stated amount. As of June 30, 2017 , the Company hedged approximately 1.4 million shares of its ordinary shares. As of September 30, 2016 , the Company had no equity swaps outstanding. The Company also holds certain foreign currency forward contracts which do not qualify for hedge accounting treatment. The change in fair value of foreign currency exchange derivatives not designated as hedging instruments under ASC 815 are recorded in the consolidated statements of income. The following table presents the location and fair values of derivative instruments and hedging activities included in the Company’s consolidated statements of financial position (in millions): Derivatives and Hedging Activities Designated as Hedging Instruments under ASC 815 Derivatives and Hedging Activities Not Designated as Hedging Instruments under ASC 815 June 30, September 30, June 30, September 30, 2017 2016 2017 2016 Other current assets Foreign currency exchange derivatives $ 7 $ 41 $ 26 $ 49 Commodity derivatives 3 4 — — Other noncurrent assets Interest rate swaps — 1 — — Equity swap — — 59 — Total assets $ 10 $ 46 $ 85 $ 49 Other current liabilities Foreign currency exchange derivatives $ 6 $ 48 $ 13 $ 18 Commodity derivatives 1 — — — Liabilities held for sale Foreign currency exchange derivatives — — — 5 Current portion of long-term debt Fixed rate debt swapped to floating — 551 — — Long-term debt Foreign currency denominated debt 1,693 938 — — Fixed rate debt swapped to floating — 301 — — Noncurrent liabilities held for sale Foreign currency denominated debt — 1,119 — — Total liabilities $ 1,700 $ 2,957 $ 13 $ 23 Counterparty Credit Risk The use of derivative financial instruments exposes the Company to counterparty credit risk. The Company has established policies and procedures to limit the potential for counterparty credit risk, including establishing limits for credit exposure and continually assessing the creditworthiness of counterparties. As a matter of practice, the Company deals with major banks worldwide having strong investment grade long-term credit ratings. To further reduce the risk of loss, the Company generally enters into International Swaps and Derivatives Association (ISDA) master netting agreements with substantially all of its counterparties. The Company's derivative contracts do not contain any credit risk related contingent features and do not require collateral or other security to be furnished by the Company or the counterparties. The Company's exposure to credit risk associated with its derivative instruments is measured on an individual counterparty basis, as well as by groups of counterparties that share similar attributes. The Company does not anticipate any non-performance by any of its counterparties, and the concentration of risk with financial institutions does not present significant credit risk to the Company. The Company enters into 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. The Company 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 the Company or the counterparties under the master netting agreements. As of June 30, 2017 and September 30, 2016 , no cash collateral was received or pledged under the master netting agreements. The gross and net amounts of derivative assets and liabilities were as follows (in millions): Fair Value of Assets Fair Value of Liabilities June 30, September 30, June 30, September 30, 2017 2016 2017 2016 Gross amount recognized $ 95 $ 95 $ 1,713 $ 2,980 Gross amount eligible for offsetting (18 ) (21 ) (18 ) (21 ) Net amount $ 77 $ 74 $ 1,695 $ 2,959 Derivatives Impact on the Statements of Income and Statements of Comprehensive Income The following table presents the effective portion of pre-tax gains (losses) recorded in other comprehensive income (loss) related to cash flow hedges for the three and nine months ended June 30, 2017 and 2016 (in millions): Derivatives in ASC 815 Cash Flow Hedging Relationships Three Months Ended June 30, Nine Months Ended June 30, 2017 2016 2017 2016 Foreign currency exchange derivatives $ (3 ) $ (5 ) $ 3 $ (11 ) Commodity derivatives 1 1 6 — Total $ (2 ) $ (4 ) $ 9 $ (11 ) The following tables present the location and amount of the effective portion of pre-tax gains (losses) on cash flow hedges reclassified from AOCI into the Company’s consolidated statements of income for the three and nine months ended June 30, 2017 and 2016 (in millions): Derivatives in ASC 815 Cash Flow Hedging Relationships Location of Gain (Loss) Reclassified from AOCI into Income Three Months Ended June 30, Nine Months Ended June 30, 2017 2016 2017 2016 Foreign currency exchange derivatives Cost of sales $ 8 $ 2 $ 24 $ 11 Foreign currency exchange derivatives Loss from discontinued operations — (10 ) — (24 ) Commodity derivatives Cost of sales 3 (2 ) 7 (11 ) Forward treasury locks Net financing charges — — — 1 Total $ 11 $ (10 ) $ 31 $ (23 ) The following table presents the location and amount of pre-tax gains (losses) on fair value hedges recognized in the Company’s consolidated statements of income for the three and nine months ended June 30, 2017 and 2016 (in millions): Derivatives in ASC 815 Fair Value Hedging Relationships Location of Gain (Loss) Recognized in Income on Derivative Three Months Ended June 30, Nine Months Ended June 30, 2017 2016 2017 2016 Interest rate swap Net financing charges $ — $ — $ (1 ) $ (3 ) Fixed rate debt swapped to floating Net financing charges — — 2 3 Total $ — $ — $ 1 $ — The following table presents the location and amount of pre-tax gains (losses) on derivatives not designated as hedging instruments recognized in the Company’s consolidated statements of income for the three and nine months ended June 30, 2017 and 2016 (in millions): Amount of Gain (Loss) Recognized in Income on Derivative Derivatives Not Designated as Hedging Instruments under ASC 815 Location of Gain (Loss) Recognized in Income on Derivative Three Months Ended June 30, Nine Months Ended June 30, 2017 2016 2017 2016 Foreign currency exchange derivatives Cost of sales $ (4 ) $ 1 $ (1 ) $ 4 Foreign currency exchange derivatives Net financing charges 51 (14 ) 60 (21 ) Foreign currency exchange derivatives Income tax provision 1 5 (2 ) 5 Foreign currency exchange derivatives Income (loss) from discontinued operations — (5 ) 5 (16 ) Equity swap Selling, general and administrative 2 20 2 12 Total $ 50 $ 7 $ 64 $ (16 ) The effective portion of pre-tax gains (losses) recorded in foreign currency translation adjustment ("CTA") within other comprehensive income (loss) related to net investment hedges were $(105) million and $(36) million for the three months ended June 30, 2017 and 2016 , respectively. The effective portion of pre-tax gains (losses) recorded in CTA within other comprehensive income (loss) related to net investment hedges were $(77) million and $(62) million for the for the nine months ended June 30, 2017 and 2016 , respectively. For the three and nine months ended June 30, 2017 and 2016 , no gains or losses were reclassified from CTA into income for the Company’s outstanding net investment hedges, and no gains or losses were recognized in income for the ineffective portion of cash flow hedges.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	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 the Company’s fair value hierarchy for those assets and liabilities measured at fair value as of June 30, 2017 and September 30, 2016 (in millions): Fair Value Measurements Using: Total as of June 30, 2017 Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Other current assets Foreign currency exchange derivatives $ 33 $ — $ 33 $ — Commodity derivatives 3 — 3 — Exchange traded funds (fixed income) 1 14 14 — — Other noncurrent assets Investments in marketable common stock 15 15 — — Deferred compensation plan assets 89 89 — — Exchange traded funds (fixed income) 1 154 154 — — Exchange traded funds (equity) 1 96 96 — — Equity swap 59 59 — — Total assets $ 463 $ 427 $ 36 $ — Other current liabilities Foreign currency exchange derivatives $ 19 $ — $ 19 $ — Commodity derivatives 1 — 1 — Long-term debt Foreign currency denominated debt 1,693 1,693 — — Total liabilities $ 1,713 $ 1,693 $ 20 $ — Fair Value Measurements Using: Total as of September 30, 2016 Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Other current assets Foreign currency exchange derivatives $ 90 $ — $ 90 $ — Commodity derivatives 4 — 4 — Exchange traded funds (fixed income) 1 15 15 — — Other noncurrent assets Interest rate swaps 1 — 1 — Investments in marketable common stock 3 3 — — Deferred compensation plan assets 81 81 — — Exchange traded funds (fixed income) 1 163 163 — — Exchange traded funds (equity) 1 86 86 — — Total assets $ 443 $ 348 $ 95 $ — Other current liabilities Foreign currency exchange derivatives $ 66 $ — $ 66 $ — Liabilities held for sale Foreign currency exchange derivatives 5 — 5 — Current portion of long-term debt Fixed rate debt swapped to floating 551 — 551 — Long-term debt Foreign currency denominated debt 938 938 — — Fixed rate debt swapped to floating 301 — 301 — Noncurrent liabilities held for sale Foreign currency denominated debt 1,119 1,119 — — Total liabilities $ 2,980 $ 2,057 $ 923 $ — 1 Classified as restricted investments for payment of asbestos liabilities. See Note 22, "Commitments and Contingencies," of the notes to consolidated financial statements for further details. Valuation Methods Foreign currency exchange derivatives : The foreign currency exchange derivatives are valued under a market approach using publicized spot and forward prices. Commodity derivatives : The commodity derivatives are valued under a market approach using publicized prices, where available, or dealer quotes. Interest rate swaps and related debt : The interest rate swaps and related debt balances are valued under a market approach using publicized swap curves. Equity swaps : The equity swaps are valued under a market approach as the fair value of the swaps is equal to the Company’s stock price at the reporting period date. Deferred compensation plan assets : Assets held in the deferred compensation plans will be used to pay benefits under certain of the Company's non-qualified deferred compensation plans. The investments primarily consist of mutual funds which are publicly traded on stock exchanges and are valued using a market approach based on the quoted market prices. Investments in marketable common stock and exchange traded funds : Investments in marketable common stock and exchange traded funds are valued using a market approach based on the quoted market prices, where available, or broker/dealer quotes of identical or comparable instruments. There was an unrealized gain recorded on these investments of $5 million as of June 30, 2017 within AOCI in the consolidated statements of financial position. There was an unrealized loss recorded on these investments of $1 million as of September 30, 2016 within AOCI in the consolidated statements of financial position. Foreign currency denominated debt: The Company has entered into a foreign currency denominated debt obligation to selectively hedge portions of its net investment in non-U.S. subsidiaries. The currency effect of the debt obligation are reflected in the AOCI account within shareholders’ equity attributable to Johnson Controls ordinary shareholders where they offset gains and losses recorded on the Company’s net investments globally. The foreign denominated debt obligation is remeasured to current exchange rates under a market approach using publicized spot prices. At June 30, 2017 , the Company had one billion euro and 485 million euro bonds designated as net investment hedges in the Company's net investment in Europe. At September 30, 2016 , the Company had 37 billion yen of foreign denominated debt designated as net investment hedge in the Company's net investment in Japan and one billion euro and 500 million euro bonds designated as net investment hedges in the Company's net investment in Europe. The fair values of cash and cash equivalents, accounts receivable, short-term debt and accounts payable approximate their carrying values. The fair value of long-term debt was $12.6 billion and $15.7 billion at June 30, 2017 and September 30, 2016 , respectively. The fair value of public debt was $8.7 billion and $9.7 billion , at June 30, 2017 and September 30, 2016 , respectively, which was determined primarily using market quotes classified as Level 1 inputs within the ASC 820 fair value hierarchy. The fair value of other long-term debt was $3.9 billion and $6.0 billion at June 30, 2017 and September 30, 2016 , respectively, which was determined based on quoted market prices for similar instruments classified as Level 2 inputs within the ASC 820 fair value hierarchy.

Disclosure of Impairment of Long-Lived Assets [Abstract]
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. The Company conducts its long-lived asset impairment analyses in accordance with ASC 360-10-15, "Impairment or Disposal of Long-Lived Assets." ASC 360-10-15 requires the Company to group assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted cash flows do not indicate the carrying amount of the asset group is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals. In the first, second and third quarters of fiscal 2017, the Company concluded it had triggering events requiring assessment of impairment for certain of its long-lived assets in conjunction with its restructuring actions announced in fiscal 2017. As a result, the Company reviewed the long-lived assets for impairment and recorded $69 million of asset impairment charges within restructuring and impairment costs on the consolidated statements of income, of which $15 million was recorded in the first quarter, $23 million was recorded in the second quarter and $31 million was recorded in the third quarter. Of the total impairment charges, $27 million related to the Tyco segment, $20 million related to the Building Efficiency Products North America segment, $17 million related to Corporate assets, $4 million related to the Power Solutions segment, and $1 million related to the Building Efficiency Systems and Services North America segment. Refer to Note 9, "Significant Restructuring and Impairment Costs," of the notes to consolidated financial statements for additional information. The impairments were measured, depending on the asset, under either an income approach utilizing forecasted discounted cash flows or a market approach utilizing an appraisal to determine fair values of the impaired assets. These methods are consistent with the methods the Company employed in prior periods to value other long-lived 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." In the second and third quarters of fiscal 2016, the Company concluded it had a triggering event requiring assessment of impairment for certain of its long-lived assets in conjunction with its restructuring actions announced in fiscal 2016. As a result, the Company reviewed the long-lived assets for impairment and recorded $65 million of asset impairment charges within restructuring and impairment costs on the consolidated statements of income, of which $15 million was recorded in the second quarter and $50 million was recorded in the third quarter. Of the total impairment charge, $50 million related to Corporate assets, $8 million related to the Building Efficiency Products North America segment, $4 million related to the Building Efficiency Asia segment and $3 million related to the Building Efficiency Rest of World segment. In addition, the Company recorded $15 million of asset impairments within discontinued operations related to Adient in fiscal 2016. Refer to Note 9, "Significant Restructuring and Impairment Costs," of the notes to consolidated financial statements for additional information. The impairments were measured, depending on the asset, under either an income approach utilizing forecasted discounted cash flows or a market approach utilizing an appraisal to determine fair values of the impaired assets. These methods are consistent with the methods the Company employed in prior periods to value other long-lived 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." At June 30, 2017 and 2016 , the Company concluded it did not have any other triggering events requiring assessment of impairment of its long-lived assets.

Guarantees [Abstract]
Guarantees	Guarantees Certain of the Company's subsidiaries at the business segment level have guaranteed the performance of third-parties and provided financial guarantees for uncompleted work and financial commitments. The terms of these guarantees vary with end dates ranging from the current fiscal year through the completion of such transactions and would typically be triggered in the event of nonperformance. Performance under the guarantees, if required, would not have a material effect on the Company's financial position, results of operations or cash flows. The Company offers warranties to its customers depending upon the specific product and terms of the customer purchase agreement. A typical warranty program requires that the Company replace defective products within a specified time period from the date of sale. The Company 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, the Company’s warranty provisions are adjusted as necessary. The Company monitors its warranty activity and adjusts its reserve estimates when it is probable that future warranty costs will be different than those estimates. The Company’s product warranty liability for continuing operations is recorded in the consolidated statements of financial position in other current liabilities if the warranty is less than one year and in other noncurrent liabilities if the warranty extends longer than one year. The changes in the carrying amount of the Company’s total product warranty liability for continuing operations, including extended warranties for which deferred revenue is recorded, for the nine months ended June 30, 2017 and 2016 were as follows (in millions): Nine Months Ended 2017 2016 Balance at beginning of period $ 374 $ 288 Accruals for warranties issued during the period 221 230 Accruals from acquisition and divestitures (1) 2 53 Accruals related to pre-existing warranties (5 ) (7 ) Settlements made (in cash or in kind) during the period (199 ) (220 ) Currency translation (1 ) 2 Balance at end of period $ 392 $ 346 June 30, 2017 includes $13 million of product warranties transferred to liabilities held for sale on the consolidated statements of financial position. Refer to Note 5, "Discontinued Operations," of the notes to consolidated financial statements for further information regarding the Company's disposal groups classified as held for sale. As a result of the Tyco Merger in the fourth quarter of fiscal 2016, the Company recorded, as part of the acquired liabilities of Tyco, $290 million of post sale contingent tax indemnification liabilities within other noncurrent liabilities in the consolidated statements of financial position. The liabilities are recorded at fair value and relate to certain tax related matters borne by the buyer of previously divested subsidiaries of Tyco which Tyco has indemnified certain parties and the amounts are probable of being paid. Of the $290 million recorded as of September 30, 2016 and June 30, 2017 , $255 million is related to prior divested businesses and the remainder relates to Tyco’s tax sharing agreements from its 2007 and 2012 spin-off transactions.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Environmental Matters The Company accrues for potential environmental liabilities when it is probable a liability has been incurred and the amount of the liability is reasonably estimable. As of June 30, 2017 , reserves for environmental liabilities totaled $48 million , of which $12 million was recorded within other current liabilities and $36 million was recorded within other noncurrent liabilities in the consolidated statements of financial position. Reserves for environmental liabilities for continuing operations totaled $51 million at September 30, 2016 . Such potential liabilities accrued by the Company 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 the Company’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, the Company does not currently believe that any claims, penalties or costs in connection with known environmental matters will have a material adverse effect on the Company’s financial position, results of operations or cash flows. In addition, the Company has identified asset retirement obligations for environmental matters that are expected to be addressed at the retirement, disposal, removal or abandonment of existing owned facilities. At June 30, 2017 and September 30, 2016 , the Company recorded conditional asset retirement obligations of $72 million and $74 million , respectively. Asbestos Matters The Company and certain of its subsidiaries, along with numerous other third parties, are named as defendants in personal injury lawsuits based on alleged exposure to asbestos containing materials. These cases have typically involved product liability claims based primarily on allegations of manufacture, sale or distribution of industrial products that either contained asbestos or were used with asbestos containing components. As of June 30, 2017 , the Company's estimated asbestos related net liability recorded on a discounted basis within the Company's consolidated statements of financial position was $147 million . The net liability within the consolidated statements of financial position was comprised of a liability for pending and future claims and related defense costs of $535 million , of which $35 million was recorded in other current liabilities and $500 million was recorded in other noncurrent liabilities. The Company also maintained separate cash, investments and receivables related to insurance recoveries within the consolidated statements of financial position of $388 million , of which $52 million was recorded in other current assets, and $336 million was recorded in other noncurrent assets. Assets included $28 million of cash and $264 million of investments, which have all been designated as restricted. In connection with the recognition of liabilities for asbestos-related matters, the Company records asbestos-related insurance recoveries that are probable; the amount of such recoveries recorded at June 30, 2017 was $96 million . As of September 30, 2016 , the Company's estimated asbestos related net liability recorded on a discounted basis within the Company's consolidated statements of financial position was $148 million . The net liability within the consolidated statements of financial position was comprised of a liability for pending and future claims and related defense costs of $548 million , of which $35 million was recorded in other current liabilities and $513 million was recorded in other noncurrent liabilities. The Company also maintained separate cash, investments and receivables related to insurance recoveries within the consolidated statements of financial position of $400 million , of which $41 million was recorded in other current assets, and $359 million was recorded in other noncurrent assets. Assets included $16 million of cash and $264 million of investments, which have all been designated as restricted. In connection with the recognition of liabilities for asbestos-related matters, the Company records asbestos-related insurance recoveries that are probable; the amount of such recoveries recorded at September 30, 2016 was $120 million . The Company believes that the asbestos related liabilities and insurance related receivables recorded as of June 30, 2017 and September 30, 2016 are appropriate. The Company's estimate of the liability and corresponding insurance recovery for pending and future claims and defense costs is based on the Company's historical claim experience, and estimates of the number and resolution cost of potential future claims that may be filed and is discounted to present value from 2069 (which is the Company's reasonable best estimate of the actuarially determined time period through which asbestos-related claims will be filed against Company affiliates). Asbestos related defense costs are included in the asbestos liability. The Company's legal strategy for resolving claims also impacts these estimates. The Company considers various trends and developments in evaluating the period of time (the look-back period) over which historical claim and settlement experience is used to estimate and value claims reasonably projected to be made through 2069. Annually, the Company assesses the sufficiency of its estimated liability for pending and future claims and defense costs by evaluating actual experience regarding claims filed, settled and dismissed, and amounts paid in settlements. In addition to claims and settlement experience, the Company considers additional quantitative and qualitative factors such as changes in legislation, the legal environment, and the Company's defense strategy. The Company also evaluates the recoverability of its insurance receivable on an annual basis. The Company evaluates all of these factors and determines whether a change in the estimate of its liability for pending and future claims and defense costs or insurance receivable is warranted. The amounts recorded by the Company for asbestos-related liabilities and insurance-related assets are based on the Company's strategies for resolving its asbestos claims, currently available information, and a number of estimates and assumptions. Key variables and assumptions include the number and type of new claims that are filed each year, the average cost of resolution of claims, the identity of defendants, the resolution of coverage issues with insurance carriers, amount of insurance, and the solvency risk with respect to the Company's insurance carriers. Many of these factors are closely linked, such that a change in one variable or assumption will impact one or more of the others, and no single variable or assumption predominately influences the determination of the Company's asbestos-related liabilities and insurance-related assets. Furthermore, predictions with respect to these variables are subject to greater uncertainty in the later portion of the projection period. Other factors that may affect the Company's liability and cash payments for asbestos-related matters include uncertainties surrounding the litigation process from jurisdiction to jurisdiction and from case to case, reforms of state or federal tort legislation and the applicability of insurance policies among subsidiaries. As a result, actual liabilities or insurance recoveries could be significantly higher or lower than those recorded if assumptions used in the Company's calculations vary significantly from actual results. Insurable Liabilities The Company records liabilities for its workers' compensation, product, general, property and auto liabilities. The determination of these liabilities and related expenses is dependent on claims experience. For most of these liabilities, claims incurred but not yet reported are estimated by utilizing actuarial valuations based upon historical claims experience. At June 30, 2017 and September 30, 2016 , the insurable liabilities for continuing operations totaled $488 million and $422 million , respectively, of which $86 million and $60 million was recorded within other current liabilities, $30 million and $28 million was recorded within accrued compensation and benefits, and $372 million and $334 million was recorded within other noncurrent liabilities in the consolidated statements of financial position, respectively. The Company records receivables from third party insurers when recovery has been determined to be probable. The amount of such receivables recorded at June 30, 2017 was $49 million , of which $30 million was recorded within other current assets and $19 million was recorded within other noncurrent assets. Insurance receivables recorded at September 30, 2016 were $21 million , primarily recorded within other noncurrent assets. The Company maintains captive insurance companies to manage certain of its insurable liabilities. The Company is involved in various lawsuits, claims and proceedings incident to the operation of its businesses, including those pertaining to product liability, environmental, safety and health, intellectual property, employment, commercial and contractual matters, and various other casualty matters. Although the outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to us, it is management’s opinion that none of these will have a material adverse effect on the Company’s financial position, results of operations or cash flows. Costs related to such matters were not material to the periods presented.
