BASIS OF PRESENTATION

BASIS OF PRESENTATION	9 Months Ended
	Sep. 30, 2021
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation [Text Block]	In the opinion of management, the accompanying unaudited Consolidated Financial Statements reflect all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the financial position, results of operations, cash flows and shareowners' equity of Honeywell International Inc. and its consolidated subsidiaries (Honeywell or the Company) for the periods presented. The interim results of operations and cash flows should not necessarily be taken as indicative of the entire year.Honeywell reports its quarterly financial information using a calendar convention; the first, second and third quarters are consistently reported as ending on March 31, June 30 and September 30. It has been Honeywell's practice to establish actual quarterly closing dates using a predetermined fiscal calendar, which requires Honeywell's businesses to close their books on a Saturday in order to minimize the potentially disruptive effects of quarterly closing on our business processes. The effects of this practice are generally not significant to reported results for any quarter and only exist within a reporting year. In the event that differences in actual closing dates are material to year-over-year comparisons of quarterly or year-to-date results, Honeywell will provide appropriate disclosures. Honeywell's actual closing dates for the three and nine months ended September 30, 2021, and September 30, 2020, were October 2, 2021, and September 26, 2020, respectively.

In December 2019, the FASB issued an ASU to simplify the accounting for income taxes. The standard’s amendments include changes in various subtopics of accounting for income taxes including, but not limited to, accounting for “hybrid” tax regimes, tax basis step-up in goodwill obtained in a transaction that is not a business combination, intraperiod tax allocation exception to incremental approach, ownership changes in investments, interim-period accounting for enacted changes in tax law, and year-to-date loss limitation in interim-period tax accounting. Effective January 1, 2021, the Company adopted this standard. The adoption of this standard did not have a material impact on the Company's Consolidated Financial Statements. In March 2020, the FASB issued guidance that provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by the transition away from reference rates expected to be discontinued to alternative reference rates. The guidance was effective upon issuance and may be applied prospectively to contract modifications made and hedging relationships entered into on or before December 31, 2022. The Company is currently evaluating the impacts of this guidance on the Company’s Consolidated Financial Statements. The Company does not expect the adoption of this standard to have a material impact on the Company’s Consolidated Financial Statements.

For a summary by disaggregated product and services sales for each segment, refer to Note 18 Segment Financial Data. The Company recognizes revenue from performance obligations to customers that are satisfied at a point in time and over time. The disaggregation of the Company's revenue based off timing of recognition is as follows: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Products, transferred point in time 58 % 61 % 58 % 61 % Products, transferred over time 16 15 17 15 Net product sales 74 76 75 76 Services, transferred point in time 9 7 8 8 Services, transferred over time 17 17 17 16 Net service sales 26 24 25 24 Net sales 100 % 100 % 100 % 100 % CONTRACT BALANCES The Company records progress on satisfying performance obligations to customers, and the related billings and cash collections, on the Consolidated Balance Sheet in Accounts receivable - net and Other assets (unbilled receivables (contract assets) and billed receivables) and Accrued liabilities and Other liabilities (customer advances and deposits (contract liabilities)). Unbilled receivables (contract assets) arise when the timing of cash collected from customers differs from the timing of revenue recognition, such as when contract provisions require specific milestones to be met before a customer can be billed. Unbilled receivable balance increases when the revenue associated with the contract is recognized prior to billing and decreases when billed in accordance with the terms of the contract. Contract liabilities increase when customers remit contractual cash payments in advance of the Company satisfying performance obligations under contractual arrangements, including those with performance obligations to be satisfied over a period of time. Contract liabilities decrease when revenue is recorded, either when a milestone is met triggering the contractual right to bill or when the performance obligation is satisfied. Contract balances are classified as assets or liabilities on a contract-by-contract basis at the end of each reporting period. The following table summarizes the Company's contract assets and liabilities balances: 2021 2020 Contract assets - January 1 $ 1,618 $ 1,602 Contract assets - September 30 2,087 1,819 Change in contract assets - increase (decrease) $ 469 $ 217 Contract liabilities - January 1 $ (4,033) $ (3,501) Contract liabilities - September 30 (3,840) (3,666) Change in contract liabilities - decrease (increase) $ 193 $ (165) Net change $ 662 $ 52 For the three and nine months ended September 30, 2021, the Company recognized revenue of $225 million and $1,786 million that was previously included in the beginning balance of contract liabilities. For the three and nine months ended September 30, 2020, the Company recognized revenue of $351 million and $1,554 million that was previously included in the beginning balance of contract liabilities. When contracts are modified to account for changes in contract specifications and requirements, the Company considers whether the modification either creates new or changes the existing enforceable rights and obligations. Contract modifications that are for goods or services that are not distinct from the existing contract, due to the significant integration with the original good or service provided, are accounted for as if they were part of that existing contract. The effect of a contract modification on the transaction price, and the Company's measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct and at relative stand-alone selling price, they are accounted for as a new contract and performance obligation, which are recognized prospectively. PERFORMANCE OBLIGATIONS A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is defined as the unit of account. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. When the Company's contracts with customers require highly complex integration or manufacturing services that are not separately identifiable from other promises in the contracts and, therefore, not distinct, then the entire contract is accounted for as a single performance obligation. In situations when the Company's contract includes distinct goods or services that are substantially the same and have the same pattern of transfer to the customer over time, they are recognized as a series of distinct goods or services. For any contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation based on the estimated relative standalone selling price of each distinct good or service in the contract. For product sales, each product sold to a customer typically represents a distinct performance obligation. In such cases, the observable standalone sales are used to determine the standalone selling price. Performance obligations are satisfied as of a point in time or over time. Performance obligations are supported by contracts with customers, providing a framework for the nature of the distinct goods, services or bundle of goods and services. The timing of satisfying the performance obligation is typically indicated by the terms of the contract. The following table outlines the Company's remaining performance obligations disaggregated by segment: September 30, 2021 Aerospace $ 8,890 Honeywell Building Technologies 6,813 Performance Materials and Technologies 7,573 Safety and Productivity Solutions 4,264 $ 27,540 Performance obligations recognized as of September 30, 2021, will be satisfied over the course of future periods. The Company's disclosure of the timing for satisfying the performance obligation is based on the requirements of contracts with customers. However, from time to time, these contracts may be subject to modifications, impacting the timing of satisfying the performance obligations. Performance obligations expected to be satisfied within one year and greater than one year are 56% and 44%, respectively. The timing of satisfaction of the Company's performance obligations does not significantly vary from the typical timing of payment. Typical payment terms of the Company's fixed-price over time contracts include progress payments based on specified events or milestones, or based on project progress. For some contracts we may be entitled to receive an advance payment. The Company applied the practical expedient for certain revenue streams to exclude the value of remaining performance obligations for (i) contracts with an original expected term of one year or less or (ii) contracts for which we recognize revenue in proportion to the amount we have the right to invoice for services performed.

The workforce reductions primarily related to the Company aligning its cost structure with the current slowdown in demand for many of the Company's products and services due to the global recession. In the nine months ended September 30, 2021, we recognized gross repositioning charges totaling $280 million including severance costs of $63 million related to workforce reductions of 5,252 manufacturing and administrative positions mainly in our Safety and Productivity Solutions and Aerospace segments. The workforce reductions were primarily related to the re-alignment of a product line in our Safety and Productivity Solutions segment, site transitions, mainly in Aerospace, to more cost-effective locations, and our productivity and ongoing functional transformation initiatives. The repositioning charge included asset impairments of $107 million primarily related to the write-down of certain manufacturing and other equipment. The repositioning charge included exit costs of $110 million primarily for current period exit costs incurred for previously approved repositioning projects, closure obligations associated with site transitions, and lease obligations for equipment. Also, $18 million of previously established reserves, primarily for severance, were returned to income due to adjustments to the scope of previously announced repositioning actions. In the nine months ended September 30, 2020, we recognized gross repositioning charges totaling $491 million including severance costs of $433 million related to workforce reductions of 13,042 manufacturing and administrative positions across the Company's segments, with a majority of the workforce reductions in Aerospace and Performance Materials and Technologies. The workforce reductions primarily related to the Company aligning its cost structure with the current slowdown in demand for many of the Company's products and services due to the global recession, and the Company's productivity and ongoing functional transformation initiatives. The repositioning charges included exit costs of $47 million primarily related to current period exit costs incurred for previously approved repositioning projects. Also, $42 million of previously established reserves, primarily for severance, were returned to income mainly as a result of higher attrition than anticipated in prior severance actions resulting in lower severance payments. The following table summarizes the status of the Company's total repositioning reserves: Severance Asset Exit Total Balance at December 31, 2020 $ 527 $ — $ 74 $ 601 Charges 63 107 110 280 Usage - cash (229) — (57) (286) Usage - noncash — (109) — (109) Foreign currency translation (2) — (2) (4) Adjustments (19) 2 (1) (18) Balance at September 30, 2021 $ 340 $ — $ 124 $ 464 Certain repositioning projects will recognize exit costs in future periods when the actual liability is incurred. Such exit costs incurred in the nine months ended September 30, 2021 and 2020, were $30 million and $32 million, respectively.

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measures	The accounting guidance for fair value measurements and disclosures establishes a three-level fair value hierarchy: • Level 1 - Inputs are based on quoted prices in active markets for identical assets and liabilities. • Level 2 - Inputs are based on observable inputs other than quoted prices in active markets for identical or similar assets and liabilities. • Level 3 - One or more inputs are unobservable and significant. Financial and nonfinancial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following table sets forth the Company’s financial assets and liabilities accounted for at fair value on a recurring basis: September 30, 2021 December 31, 2020 Assets: Foreign currency exchange contracts $ 303 $ 202 Available for sale investments 994 1,118 Interest rate swap agreements 100 194 Cross currency swap agreements 13 — Investments in equity securities 52 11 Liabilities: Foreign currency exchange contracts $ 219 $ 150 Cross currency swap agreements — 50 The foreign currency exchange contracts, interest rate swap agreements, and cross currency swap agreements are valued using broker quotations or market transactions in either the listed or over-the-counter markets. As such, these derivative instruments are classified within level 2. The Company also holds investments in commercial paper, certificates of deposits, and time deposits that are designated as available for sale, as well as investments in equity securities, which are valued using published prices based off observable market data. As such, these investments are classified within level 2. The Company holds certain available for sale investments in U.S. government and corporate debt securities, as well as investments in equity securities, which are valued utilizing published prices based on quoted market pricing, which are classified within level 1. The carrying value of cash and cash equivalents, trade accounts and notes receivables, payables, commercial paper, and short-term borrowings approximates fair value. The following table sets forth the Company’s financial assets and liabilities that were not carried at fair value: September 30, 2021 December 31, 2020 Carrying Fair Carrying Fair Assets Short-term investment $ 242 $ 242 $ — $ — Long-term receivables $ 170 $ 155 $ 137 $ 132 Long-term investment 353 353 — — Liabilities Long-term debt and related current maturities $ 17,690 $ 18,888 $ 18,787 $ 20,176 The Company determined the fair value of the long-term receivables by utilizing transactions in the listed markets for identical or similar assets. As such, the fair values of these receivables are considered level 2.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	ENVIRONMENTAL MATTERS Our environmental matters are described in Note 20 Commitments and Contingencies of Notes to Consolidated Financial Statements in our 2020 Annual Report on Form 10-K. The following table summarizes information concerning our recorded liabilities for environmental costs: Balance at December 31, 2020 $ 660 Accruals for environmental matters deemed probable and reasonably estimable 126 Environmental liability payments (147) Balance at September 30, 2021 $ 639 Environmental liabilities are included in the following balance sheet accounts: September 30, 2021 December 31, 2020 Accrued liabilities $ 225 $ 225 Other liabilities 414 435 $ 639 $ 660 The Company does not currently possess sufficient information to reasonably estimate the amounts of environmental liabilities to be recorded upon future completion of studies, litigation or settlements, and neither the timing nor the amount of the ultimate costs associated with environmental matters can be determined although they could be material to our consolidated results of operations and operating cash flows in the periods recognized or paid. However, considering our past experience and existing reserves, the Company does not expect that environmental matters will have a material adverse effect on its consolidated financial position. In conjunction with the Resideo Technologies, Inc. (Resideo) spin-off, the Company entered into an indemnification and reimbursement agreement with a Resideo subsidiary, pursuant to which Resideo’s subsidiary has an ongoing obligation to make cash payments to Honeywell in amounts equal to 90% of Honeywell’s annual net spending for environmental matters at certain sites as defined in the agreement. The amount payable to Honeywell in any given year is subject to a cap of $140 million, and the obligation will continue until the earlier of December 31, 2043, or December 31, of the third consecutive year during which the annual payment obligation is less than $25 million. Reimbursements associated with this agreement are collected from Resideo quarterly and were $35 million and $105 million in the three and nine months ended September 30, 2021, respectively, and offset operating cash outflows incurred by the Company. As the Company incurs costs for environmental matters deemed probable and reasonably estimable related to the sites covered by the indemnification and reimbursement agreement, a corresponding receivable from Resideo for 90% of such costs is also recorded. This receivable amount recorded in the nine months ended September 30, 2021, was $111 million. As of September 30, 2021, Other current assets and Other assets included $140 million and $457 million, respectively, for the short-term and long-term portion of the receivable amount due from Resideo under the indemnification and reimbursement agreement. ASBESTOS MATTERS Honeywell is named in asbestos-related personal injury claims related to North American Refractories Company (NARCO), which was sold in 1986, and the Bendix Friction Materials (Bendix) business, which was sold in 2014. The following tables summarize information concerning NARCO and Bendix asbestos-related balances: ASBESTOS-RELATED LIABILITIES Bendix NARCO Total December 31, 2020 $ 1,441 $ 779 $ 2,220 Accrual for update to estimated liability 40 19 59 Asbestos-related liability payments (107) (107) (214) September 30, 2021 $ 1,374 $ 691 $ 2,065 INSURANCE RECOVERIES FOR ASBESTOS-RELATED LIABILITIES Bendix NARCO Total December 31, 2020 $ 148 $ 254 $ 402 Probable insurance recoveries related to estimated liability — — — Insurance receipts for asbestos-related liabilities (10) (27) (37) Insurance receivables settlements — — — September 30, 2021 $ 138 $ 227 $ 365 NARCO and Bendix asbestos-related balances are included in the following balance sheet accounts: September 30, 2021 December 31, 2020 Other current assets $ 35 $ 36 Insurance recoveries for asbestos-related liabilities 330 366 $ 365 $ 402 Accrued liabilities $ 300 $ 300 Asbestos-related liabilities 1,765 1,920 $ 2,065 $ 2,220 NARCO Products – NARCO manufactured high-grade, heat-resistant, refractory products for various industries. Honeywell’s predecessor, Allied Corporation, owned NARCO from 1979 to 1986. Allied Corporation sold the NARCO business in 1986 and entered into a cross-indemnity agreement which included an obligation to indemnify the purchaser for asbestos claims, arising primarily from alleged occupational exposure to asbestos-containing refractory brick and mortar for high-temperature applications. NARCO ceased manufacturing these products in 1980 and filed for bankruptcy in January 2002, at which point in time all then current and future NARCO asbestos claims were stayed against both NARCO and Honeywell pending the reorganization of NARCO. The Company established its initial liability for NARCO asbestos claims in 2002. NARCO emerged from bankruptcy in April 2013, at which time a federally authorized 524(g) trust was established to evaluate and resolve all existing NARCO asbestos claims (the Trust). Both Honeywell and NARCO are protected by a permanent channeling injunction barring all present and future individual actions in state or federal courts and requiring all asbestos-related claims based on exposure to NARCO asbestos-containing products to be made against the Trust. The NARCO Trust Agreement (TA) and the NARCO Trust Distribution Procedures (TDP) set forth the structure and operating rules of the Trust, and established Honeywell’s evergreen funding obligations. In accordance with the TA, the Trust is eligible to receive cash dividends from Harbison-Walker International Inc. (HWI), the reorganized and renamed entity that emerged from the NARCO bankruptcy. HWI cash dividends are required to be used to pay asbestos-related claims which qualify for payment under the TDP (Annual Contribution Claims) until those funds are exhausted, at which point Honeywell’s funding obligation, subject to an annual cap of $145 million, is triggered. The Company is also required to fund amounts owed pursuant to settlement agreements reached during the pendency of the NARCO bankruptcy proceedings that provide for the right to submit claims to the Trust subject to qualification under the terms of the settlement agreements and TDP (Pre-Established Unliquidated Claims), as well as fund the annual operating costs of the Trust. There is no annual funding cap relative to Pre-Established Unliquidated Claims. In July 2021, HWI paid a dividend of $47 million to the Trust. The operating rules per the TDP defines criteria claimants must meet for a claim to be considered valid and paid, which include adequate medical evidence of the claimant’s asbestos-related condition and credible evidence of exposure to a specific NARCO asbestos-containing product. The TDP allows Honeywell to audit claim support documents against these criteria. Once operational in 2014, the Trust began to receive, process and pay claims. The Company identified several issues with the way the Trust was adhering to the TDP in audits subsequent to the Trust becoming operational. The Company continued to identify and dispute these matters as further claims have been and are processed. In September 2021, Honeywell filed suit against the Trust in Bankruptcy Court alleging, among other claims, breach of certain provisions of the TA and TDP. The Trust also filed suit against Honeywell, alleging Honeywell has breached its obligations under the Trust's governing documents. At this time, we cannot predict the outcome of these matters. Due to the bankruptcy filing in 2002, claimants were not permitted to file additional claims until the Trust became operative in 2014. As a consequence, there was a large backlog of claims filed with the Trust upon it becoming operative in 2014 through December 31, 2017, the date by which these claims had to be filed or else be barred by the expiration of the statute of limitations. Therefore, the claims filing rate did not start to normalize until 2018 and thereafter. As a result, between 2002 and 2018, the Company lacked a history of sufficiently reliable claims data to derive a reasonable estimate of its NARCO asbestos-related liability, and the Company continued to update its original estimate, as appropriate, using all available information. In 2020, with three years of sufficiently reliable claims data, the Company updated its estimate of the NARCO asbestos-related liability utilizing claims data from January 1, 2018 through December 31, 2020. The Company utilizes an asbestos liability valuation specialist to support our preparation of the NARCO asbestos-related liability estimates. Our estimates, which involve significant management judgment, consider multiple scenarios, including a scenario adjusting for the impact of the COVID-19 pandemic on the Trust's ability to process claims during 2020. The estimate for the resolution of asserted Annual Contribution Claims and Pre-Established Unliquidated Claims uses average payment values for the relevant historical period. For unasserted claims, the estimate is based on historic and anticipated claims filing experience and payment rates, disease classifications and type of claim, and average payment values by the Trust for the relevant historical period. The Company's estimate also includes all years of epidemiological disease projection through 2059. The NARCO asbestos-related liability reflects an estimate for the resolution of Annual Contribution Claims and Pre-Established Unliquidated Claims filed with the Trust, as well as for unasserted Annual Contribution Claims and Pre-Established Unliquidated Claims. The NARCO asbestos-related liability excludes the annual operating expenses of the Trust which are expensed as they are incurred. The Company's NARCO-related insurance receivable reflects coverage which reimburses Honeywell for portions of NARCO-related claims and defense costs. This coverage is provided by a large number of insurance policies written by dozens of insurance companies in both the domestic insurance market and the London excess market. Honeywell's NARCO-related insurance receivable is an estimate of the probable amount of insurance that is recoverable for asbestos claims. Most of our insurance carriers remain solvent. However, select individual insurance carriers are now insolvent, which we have considered in our analysis of probable recoveries. Our judgments related to our insurance carriers and insurance coverages are reasonable and consistent with Honeywell's historical dealings and Honeywell's knowledge of any pertinent solvency issues surrounding insurers. Bendix Products – Bendix manufactured automotive brake linings that contained chrysotile asbestos in an encapsulated form. Claimants consist largely of individuals who allege exposure to asbestos from brakes from either performing or being in the vicinity of individuals who performed brake replacements. The following tables present information regarding Bendix-related asbestos claims activity: Nine Months Ended Years Ended Claims Activity 2021 2020 2019 Claims unresolved at the beginning of period 6,242 6,480 6,209 Claims filed 1,883 2,233 2,659 Claims resolved (1,465) (2,471) (2,388) Claims unresolved at the end of period 6,660 6,242 6,480 September 30, December 31, Disease Distribution of Unresolved Claims 2021 2020 2019 Mesothelioma and other cancer claims 3,968 3,422 3,399 Nonmalignant claims 2,692 2,820 3,081 Total claims 6,660 6,242 6,480 Years Ended December 31, 2020 2019 2018 2017 2016 (in whole dollars) Malignant claims $ 61,500 $ 50,200 $ 55,300 $ 56,000 $ 44,000 Nonmalignant claims $ 550 $ 3,900 $ 4,700 $ 2,800 $ 4,485 It is not possible to predict whether resolution values for Bendix-related asbestos claims will increase, decrease or stabilize in the future. The Consolidated Financial Statements reflect an estimated liability for resolution of asserted (claims filed as of the financial statement date) and unasserted Bendix-related asbestos claims, which exclude the Company’s ongoing legal fees to defend such asbestos claims which will continue to be expensed as they are incurred. The Company reflects the inclusion of all years of epidemiological disease projection through 2059 when estimating the liability for unasserted Bendix-related asbestos claims. Such liability for unasserted Bendix-related asbestos claims is based on historic and anticipated claims filing experience and dismissal rates, disease classifications, and resolution values in the tort system for the previous five years. The Company has valued Bendix asserted and unasserted claims using average resolution values for the previous five years. The Company updates the resolution values used to estimate the cost of Bendix asserted and unasserted claims during the fourth quarter each year. The Company's insurance receivable corresponding to the liability for settlement of asserted and unasserted Bendix asbestos claims reflects coverage which is provided by a large number of insurance policies written by dozens of insurance companies in both the domestic insurance market and the London excess market. Based on our ongoing analysis of the probable insurance recovery, insurance receivables are recorded in the financial statements simultaneous with the recording of the estimated liability for the underlying asbestos claims. This determination is based on our analysis of the underlying insurance policies, our historical experience with our insurers, our ongoing review of the solvency of our insurers, judicial determinations relevant to our insurance programs, and our consideration of the impacts of any settlements reached with our insurers. On October 31, 2018, David Kanefsky, a Honeywell shareholder, filed a putative class action complaint in the U.S. District Court for the District of New Jersey alleging violations of the Securities Exchange Act of 1934 and Rule 10b-5 related to the prior accounting for Bendix asbestos claims. An Amended Complaint was filed on December 30, 2019, and on February 7, 2020, we filed a Motion to Dismiss. On May 18, 2020, the court denied our Motion to Dismiss. We believe the claims have no merit. GARRETT LITIGATION AND BANKRUPTCY PROCEEDINGS In conjunction with the Garrett spin-off, the Company entered into a binding indemnification and reimbursement agreement (Garrett Indemnity) and a binding tax matters agreement (Tax Matters Agreement) with Garrett and a Garrett subsidiary. On December 2, 2019, Garrett and Garrett ASASCO Inc. filed a Summons with Notice and commenced a lawsuit in the Commercial Division of the Supreme Court of the State of New York, County of New York (the State Court), seeking to invalidate the Garrett Indemnity. Garrett sought damages and a declaratory judgment based on various claims set forth in the Summons with Notice. On July 17, 2020, the Company received a notice from Garrett asserting that the Company had caused material breaches of the Tax Matters Agreement and that the Tax Matters Agreement was unenforceable. On September 20, 2020, Garrett and 36 of its affiliates filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Southern District of New York (the Bankruptcy Court). On September 24, 2020, Garrett moved the existing State Court litigation against Honeywell to the Bankruptcy Court. On April 26, 2021, the Bankruptcy Court confirmed Garrett’s amended Chapter 11 plan of reorganization (the Confirmed Plan), and on April 30, 2021 (the Effective Date), Garrett emerged from bankruptcy. On the Effective Date, and in accordance with the Confirmed Plan, (i) the Company received from Garrett an initial payment of $375 million and 834.8 million shares of Garrett's Series B Preferred Stock in full and final satisfaction of the Garrett Indemnity and Tax Matters Agreement, (ii) the Garrett Indemnity and Tax Matters Agreement were terminated, (iii) the Company and Garrett mutually released each other from the claims asserted in all pending legal actions related to the Garrett Indemnity and Tax Matters Agreement, and (iv) all pending litigation between the Company and Garrett in connection with those agreements was resolved. The Series B Preferred Stock Certificate of Designation provides for mandatory redemptions by Garrett of $35 million in 2022 and $100 million per year from 2023 to 2030 (inclusive) at the anniversary of the Effective Date, unless (i) Garrett’s consolidated EBITDA as of the end of the most recently completed fiscal year is less than $425 million, or (ii) Garrett does not have sufficient funds available to pay the redemption, at which point the redemption amounts past due will accrue interest. The Series B Preferred Stock Certificate of Designation also includes rights which allow (a) the Company to put the Series B Preferred Stock to Garrett if certain EBITDA conditions are met, and (b) Garrett to call the Series B Preferred Stock in whole or in part if certain EBITDA conditions are met. On September 30, 2021, Garrett filed an Amended and Restated Series B Preferred Stock Certificate of Designation with the Secretary of State of Delaware. The Amended and Restated Series B Preferred Stock Certificate of Designation requires Garrett to partially redeem a portion of the Series B Preferred Stock on or before March 31, 2022, such that the present value of remaining outstanding shares of the Series B Preferred Stock will be $400 million, subject to applicable law, including that Garrett has funds legally available for the partial redemption. Such redemption would be applied to the latest scheduled redemption dates, beginning with the shares to be redeemed in 2030. The Amended and Restated Series B Preferred Stock Certificate of Designation also provides that the Company cannot exercise its right to put the Series B Preferred Stock to Garrett until after December 31, 2022, subject to the EBITDA conditions described in the above section, unless the partial redemption does not occur on or before March 31, 2022. All other material terms and conditions in the Amended and Restated Series B Preferred Stock Certificate of Designation are unchanged from the original Series B Preferred Stock Certificate of Designation, including the scheduled redemption payment by Garrett of $35 million due April 30, 2022. We recorded the Series B Preferred Stock at fair value at the Effective Date. We believe the present value of the mandatory redemptions is an appropriate basis for determining the fair value of the Series B Preferred Stock. Our present value reflects amortized cost determined by the present value of the mandatory redemptions discounted at 7.25%, which is the rate reflected in the Series B Preferred Stock Certificate of Designation. The discount amount will accrete into interest income over the mandatory redemption period. In addition to the Series B Preferred Stock, the Company subscribed for 4.2 million shares of Garrett's Series A Preferred Stock, which are convertible into Garrett’s Common Stock if certain conditions are met. Prior to and following Garrett’s emergence from bankruptcy, the Company also held 2.9 million shares of Garrett’s Common Stock. As of September 30, 2021, Short-term investments included $242 million and Investments and long-term receivables included $405 million for the Company's investments in Garrett's Series B Preferred Stock, Series A Preferred Stock and Common Stock. The Garrett matter and bankruptcy proceedings are described in further detail in Note 20 Commitments and Contingencies of Notes to Consolidated Financial Statements in our 2020 Annual Report on Form 10-K. OTHER MATTERS The Company is subject to a number of other lawsuits, investigations and disputes (some of which involve substantial amounts claimed) arising out of the conduct of our business, including matters relating to commercial transactions, government contracts, product liability, prior acquisitions and divestitures, employee benefit plans, intellectual property, and environmental, health and safety matters (including the matter described below). We recognize a liability for any contingency that is probable of occurrence and reasonably estimable. We continually assess the likelihood of adverse judgments or outcomes in such matters, as well as potential ranges of possible losses (taking into consideration any insurance recoveries), based on a careful analysis of each matter with the assistance of outside legal counsel and, if applicable, other experts. Such matters include: • Petrobras and Unaoil – We continue to cooperate with investigations by the U.S. Department of Justice (DOJ), the Securities and Exchange Commission (SEC) and the Brazilian authorities relating to our use of third parties who previously worked for our UOP business in Brazil in relation to Petróleo Brasileiro S.A. (Petrobras) in connection with a project awarded in 2010. The investigations focus on compliance with the U.S. Foreign Corrupt Practices Act and similar Brazilian laws (the UOP Matters), and involve, among other things, document production and interviews with former and current management and employees. The DOJ and the SEC are also examining a matter involving a foreign subsidiary’s prior contract with Unaoil S.A.M. in Algeria executed in 2011. We continue to be engaged in discussions with the authorities with respect to a potential comprehensive resolution of these matters.

	Sep. 30, 2021
Accounting Policies [Abstract]
Reclassifications	Certain prior year amounts have been reclassified to conform to the current year presentation.
Recent Accounting Pronouncements	The Company considers the applicability and impact of all Accounting Standards Updates (ASUs) issued by the Financial Accounting Standards Board (FASB). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our Consolidated Financial Statements. In December 2019, the FASB issued an ASU to simplify the accounting for income taxes. The standard’s amendments include changes in various subtopics of accounting for income taxes including, but not limited to, accounting for “hybrid” tax regimes, tax basis step-up in goodwill obtained in a transaction that is not a business combination, intraperiod tax allocation exception to incremental approach, ownership changes in investments, interim-period accounting for enacted changes in tax law, and year-to-date loss limitation in interim-period tax accounting. Effective January 1, 2021, the Company adopted this standard. The adoption of this standard did not have a material impact on the Company's Consolidated Financial Statements. In March 2020, the FASB issued guidance that provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by the transition away from reference rates expected to be discontinued to alternative reference rates. The guidance was effective upon issuance and may be applied prospectively to contract modifications made and hedging relationships entered into on or before December 31, 2022. The Company is currently evaluating the impacts of this guidance on the Company’s Consolidated Financial Statements. The Company does not expect the adoption of this standard to have a material impact on the Company’s Consolidated Financial Statements.
