(1)Net of changes in valuation allowance

(2)Includes U.S. taxes on non-U.S. earnings

The effective tax rate increased by 1.5 percentage points in 2020 compared to 2019. The increase was primarily attributable to accrued withholding taxes related to unremitted foreign earnings and non-cash charges related to the reduction of the aggregate carrying value of certain receivables with no corresponding tax benefit, offset by the favorable resolution of a foreign tax matter related to the previously completed spin-off transactions, tax impact of restructuring, tax law changes in India, and the resolution of certain U.S. tax matters. The Company’s non-U.S. effective tax rate was 11.9%, a decrease of approximately 14.2 percentage points compared to 2019. The decrease in the foreign effective tax rate was primarily attributable to the favorable resolution of a foreign tax matter related to the previously completed spin-off transactions, tax impact of restructuring, and tax law changes in India offset by accrued withholding taxes related to unremitted foreign earnings.

The effective tax rate increased by 8.8 percentage points in 2019 compared to 2018. The increase was primarily attributable to a lower income tax benefit resulting from revised guidance related to the U.S. Tax Cuts and Jobs Act and internal restructuring initiatives that resulted in a $281 million reduction of accrued withholding taxes related to unremitted foreign earnings when compared to the prior year. The Company’s non-U.S. effective tax rate was 26.1%, an increase of approximately 22.0 percentage points compared to 2018. The increase in the foreign effective tax rate was primarily attributable to a lower income tax benefit related to the Company’s internal restructuring initiatives when compared to the prior year.

DEFERRED TAX ASSETS (LIABILITIES)

The tax effects of temporary differences and tax carryforwards which give rise to future income tax benefits and payables are as follows:


Deferred tax assets:	December 31,
	2020		2019
Postretirement benefits other than pensions	$	85	$	111
Asbestos and environmental	508		531
Employee compensation and benefits	180		205
Lease liabilities	197		167
Other accruals and reserves	110		279
Net operating and capital losses	779		652
Tax credit carryforwards	219		246
Gross deferred tax assets	2,078		2,191
Valuation allowance	(766)		(656)
Total deferred tax assets	$	1,312	$	1,535
Deferred tax liabilities:
Pension	$	(548)	$	(469)
Property, plant and equipment	(437)		(477)
Right-of-use asset	(184)		(159)
Intangibles	(898)		(1,296)
Unremitted earnings of foreign subsidiaries	(398)		(419)
Other asset basis differences	(169)		(136)
Other	(31)		(163)
Total deferred tax liabilities	(2,665)		(3,119)
Net deferred tax liability	$	(1,353)	$	(1,584)

The Company's gross deferred tax assets include $872 million related to non-U.S. operations comprised principally of net operating losses, capital loss and tax credit carryforwards (mainly in Canada, France, Germany, Luxembourg and the United Kingdom) and deductible temporary differences. We maintain a valuation allowance of $758 million against a portion of the non-U.S. gross deferred tax assets. The change in the valuation allowance resulted in an increase of $105 million, a decrease of $23 million and an increase of $57 million to income tax expense in 2020, 2019 and 2018. In the event we determine that we will not be able to realize our net deferred tax assets in the future, we will reduce such amounts through an increase to income tax expense in the period such determination is made. Conversely, if we determine that we will be able to realize net deferred tax assets in excess of the carrying amounts, we will decrease the recorded valuation allowance through a reduction to income tax expense in the period that such determination is made.

As of December 31, 2020, the Company recorded a $398 million deferred tax liability on all our unremitted foreign earnings based on estimated earnings and profits of approximately $22.4 billion as of the balance sheet date.

As of December 31, 2020, the Company's net operating loss, capital loss and tax credit carryforwards were as follows:


Jurisdiction	Expiration Period	Net Operating and Capital Loss Carryforwards		Tax Credit Carryforwards
U.S. Federal	2040	$	24	$	92
U.S. State	2040	382		21
Non-U.S.	2040	314		111
Non-U.S.	Indefinite	2,532		—
		$	3,252	$	224

Many jurisdictions impose limitations on the timing and utilization of net operating loss and tax credit carryforwards. In those instances, whereby there is an expected permanent limitation on the utilization of the net operating loss or tax credit carryforward, the deferred tax asset and amount of the carryforward have been reduced.

As of December 31, 2020, 2019 and 2018, there were $991 million, $1,164 million, and $1,089 million of unrecognized tax benefits that if recognized would be recorded as a component of Tax expense.

The following table summarizes tax years that remain subject to examination by major tax jurisdictions as of December 31, 2020:


Jurisdiction	Open Tax Years Based on Originally Filed Returns
	Examination in progress	Examination not yet initiated
U.S. Federal	2017 - 2018	2019 - 2020
U.S. State	2011 - 2019	2016 - 2019

United Kingdom	2013 - 2018	2019 - 2020

(1)Includes provincial or similar local jurisdictions, as applicable.

Based on the outcome of these examinations, or as a result of the expiration of statute of limitations for specific jurisdictions, it is reasonably possible that certain unrecognized tax benefits for tax positions taken on previously filed tax returns will materially change from those recorded as liabilities in our financial statements. In addition, the outcome of these examinations may impact the valuation of certain deferred tax assets (such as net operating losses) in future periods.

Unrecognized tax benefits for examinations in progress were $556 million, $413 million and $304 million, as of December 31, 2020, 2019 and 2018. Estimated interest and penalties related to the underpayment of income taxes are classified as a component of Tax expense in the Consolidated Statement of Operations and totaled $80 million, $73 million and $45 million for the years ended December 31, 2020, 2019 and 2018. Accrued interest and penalties were $507 million, $487 million and $426 million, as of December 31, 2020, 2019 and 2018.

During the third quarter of 2020, the Company changed the method of valuing inventory from the last-in, first-out (LIFO) method to the first-in, first-out (FIFO) method for inventories within our Performance Materials and Technologies segment not previously valued using FIFO. The Company believes the FIFO method is preferable and better reflects the current value of inventory reported in the Consolidated Balance Sheet. The cumulative effect of this change in accounting principle was $7 million and was recorded as a reduction to Cost of products sold for the year ended December 31, 2020. The inventories subject to this change totaled approximately 6% of consolidated inventories at the time of this change. This change was not material to the Consolidated Financial Statements, and therefore prior periods were not adjusted retrospectively. Inventories valued at LIFO amounted to $292 million at December 31, 2019. Had such LIFO inventories been valued at current costs, the carrying values would have been approximately $45 million higher at December 31, 2019. There are no remaining inventories valued at LIFO.

The Company may redeem the 2022 floating rate notes at any time, in whole or in part, on or after August 19, 2021. The 2022 Callable Notes resulted in gross proceeds of $3.0 billion, offset by $10 million in discount and closing costs related to the offering. The Company used the proceeds of the offering to repay $3.0 billion of borrowings under the Term Loan Agreement (defined below).

On May 18, 2020, the Company issued $1.25 billion 1.35% Senior Notes due 2025, $1.0 billion 1.95% Senior Notes due 2030, and $750 million 2.80% Senior Notes due 2050 (collectively, the 2020 Notes) to replace and, accordingly, permanently reduce $3.0 billion of undrawn commitments under the Term Loan Agreement, referenced below. The Company may redeem the 2020 Notes at any time, in whole or in part, at the Company's option. The offering provided gross proceeds of $3.0 billion, offset by $27 million in discount and closing costs related to the offering.

The 2022 Callable Notes, 2020 Notes, and 2020 Euro Notes are senior unsecured and unsubordinated obligations of the Company and rank equally with each other and with all of the Company's existing and future senior unsecured debt and senior to all of the Company's subordinated debt.

On April 10, 2020, the Company entered into a $1.5 billion 364-Day Credit Agreement (the 364-Day Credit Agreement) with a syndicate of banks. This 364-Day Credit Agreement is maintained for general corporate purposes.

On March 26, 2020, the Company entered into a Delayed Draw Term Loan Agreement (the Term Loan Agreement) with a syndicate of banks. The Term Loan Agreement provided for a two-year, delayed draw term loan facility in the aggregate principal amount of $6.0 billion. Effective May 22, 2020, the Company permanently reduced the undrawn commitments under the Term Loan Agreement by an aggregate amount of $3.0 billion. On June 24, 2020, the Company drew on the remaining $3.0 billion of commitments under the Term Loan Agreement at a variable interest rate equal to the one-month LIBOR plus the applicable margin of 1.25%. The draw provided gross proceeds of $3.0 billion, offset by $7 million in closing costs related to the borrowing. On August 20, 2020, the Company prepaid the outstanding principal amount of $3.0 billion, using the proceeds from the offering of the 2022 Callable Notes.

On February 21, 2020, the Company paid its 0.65% Euro notes due 2020.

On April 26, 2019, the Company entered into a $4.0 billion Five Year Credit Agreement (the 5-Year Credit Agreement) with a syndicate of banks, dated April 26, 2019. This 5-Year Credit Agreement is maintained for general corporate purposes. Commitments under the 5-Year Credit Agreement can be increased pursuant to the terms of the 5-Year Credit Agreement to an aggregate amount not to exceed $4.5 billion.

As of December 31, 2020, there were no outstanding borrowings under the 364-Day Credit Agreement, Term Loan Agreement, or 5-Year Credit Agreement.

In 2020, the Company recognized repositioning charges totaling $565 million, including severance costs of $475 million related to workforce reductions of 14,159 manufacturing and administrative positions across our 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 slowdown in demand for many of its products and services due to the global recession, and with our productivity and ongoing functional transformation initiatives and to site consolidations and hub strategies. The repositioning charge included exit costs of $69 million primarily related to current period exit costs incurred for previously approved repositioning projects. Also, $47 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 payments.

In 2019, the Company recognized repositioning charges totaling $438 million, including severance costs of $260 million related to workforce reductions of 5,336 manufacturing and administrative positions across our segments. The workforce reductions related to our productivity and ongoing functional transformation initiatives and to site transitions, mainly in Honeywell Building Technologies, as we transition manufacturing to more cost-effective

locations. The repositioning charge included asset impairments of $95 million largely related to a write down in connection with assets held for sale. The repositioning charge included exit costs of $83 million primarily related to current period exit costs incurred for previously approved repositioning projects, termination fees associated with the early cancellation of supply agreements for certain raw materials in Performance Materials and Technologies and Honeywell Building Technologies and for closure obligations associated with site transitions.

In 2018, the Company recognized repositioning charges totaling $530 million, including severance costs of $289 million related to workforce reductions of 6,486 manufacturing and administrative positions across our segments. The workforce reductions were primarily related to planned site closures, mainly in Safety and Productivity Solutions, Performance Materials and Technologies and Honeywell Building Technologies, as we transition manufacturing sites to more cost-effective locations. The workforce reductions were also related to our productivity and ongoing functional transformation initiatives. The repositioning charge included asset impairments of $162 million mainly related to manufacturing plant and equipment associated with planned site closures. Asset impairments also included the write-down of a legacy property in Corporate in connection with its planned disposition and the write-off of certain capitalized assets in Corporate. The repositioning charge included exit costs of $79 million primarily related to a termination fee associated with the early cancellation of a supply agreement for certain raw materials in Performance Materials and Technologies and for closure obligations associated with planned site closures.

The following table summarizes the status of the Company's total repositioning reserves:

Certain repositioning projects will recognize exit costs in future periods when the actual liability is incurred. Such exit costs incurred in 2020, 2019 and 2018 were not significant.

In 2018, the other charge of $63 million mainly relates to reserves taken due to the required wind-down of the Company's activities in Iran and the evaluation of potential resolution of a certain legal matter.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS AND DIVESTITURES During 2020, the Company acquired businesses for an aggregate cost (net of cash and debt assumed) of approximately $261 million, which included the October 2020 acquisition of Rocky Research and the December 2020 acquisition of Sine Group. Rocky Research is a technology leader specializing in thermal, energy and power management solutions and is included within our Aerospace segment. Sine Group offers a Software-as-a-Service (SaaS) that handles visitor management, workplace and supply chain solutions and is included in the Honeywell Building Technologies segment. The preliminary determination of the assets and liabilities acquired with Rocky Research and Sine Group is included in the Consolidated Balance Sheet as of December 31, 2020, including $167 million allocated to goodwill, which is non-deductible for tax purposes. There were no significant divestitures during 2020. On December 22, 2020, the Company agreed to acquire 100% of the outstanding stock of Sparta Systems from New Mountain Capital in an all-cash transaction for $1.3 billion. Sparta Systems is a leading provider of enterprise quality management software for the life sciences industry and is expected to further strengthen the Company's leadership in industrial automation, digital transformation solutions, and enterprise performance management software. The transaction is subject to regulatory review and approval and customary closing conditions. The transaction is expected to close in the first quarter of 2021 and the business will be reported within the Performance Materials and Technologies segment. During 2019, there were no significant acquisitions or divestitures individually or in the aggregate. During 2018, the Company acquired businesses for an aggregate cost (net of cash and debt assumed) of approximately $535 million, mainly due to the November 2018 acquisition of Transnorm, a global leader in high-performance conveyor and warehouse solutions, including approximately $380 million allocated to goodwill. Transnorm is part of Safety and Productivity Solutions. The goodwill is non-deductible for tax purposes. On October 1, 2018, the Company completed the tax-free spin-off to Honeywell shareowners of its Transportation Systems business, part of Aerospace, into a standalone publicly-traded company, Garrett. On October 29, 2018, the Company completed the tax-free spin-off to Honeywell shareowners of its Homes and Global Distribution business, part of Home and Building Technologies (renamed Honeywell Building Technologies following the spin-off), into a standalone publicly-traded company, Resideo. The assets of approximately $5.5 billion, including approximately $2.8 billion of goodwill and net of recorded receivables, and liabilities of approximately $7.2 billion, associated with the spin-off entities were removed through Retained Earnings from the Company’s Consolidated Balance Sheet as of the effective date of the spin-off. The results of operations and cash flows are included in the Consolidated Statement of Operations and Consolidated Statement of Cash Flows through the effective date of the spin-off. The Income before taxes attributable to the spin-off businesses were $0.4 billion for 2018. Honeywell shareowners of record as of the close of business on October 16, 2018 received one share of Resideo common stock for every 6 shares of Honeywell common stock. Immediately prior to the effective date of the spin-off, Resideo incurred debt of $1.2 billion to make a cash distribution to the Company. Honeywell shareowners of record as of the close of business on September 18, 2018 received one share of Garrett common stock for every 10 shares of Honeywell common stock. Immediately prior to the effective date of the spin-off, Garrett incurred debt of $1.6 billion to make a cash distribution to the Company. In 2018, in connection with the spin-off, the Company entered into certain agreements with Resideo and Garrett to effect our legal and structural separation, including transition services agreements to provide certain administrative and other services for a limited time, and tax matters and indemnification and reimbursement agreements.

DERIVATIVE INSTRUMENTS AND HEDGING TRANSACTIONS

12 Months Ended

Dec. 31, 2020

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

DERIVATIVES AND HEDGING ACTIVITIES

The Company uses derivative financial instruments to manage its risks related to interest rates and foreign currency exchange rate fluctuations. Derivative financial instruments are not used for trading or other speculative purposes. To qualify as a hedge, derivative financial instruments must be evaluated for hedge effectiveness at the inception of the contract and designated as a hedge. Changes in fair value of the derivative contract must be highly correlated with changes in fair value of the underlying hedged item at inception and over the life of the hedge contract.

FOREIGN CURRENCY RISK MANAGEMENT

The Company operates a global business in a wide variety of foreign currencies. Our exposure to market risk for changes in foreign currency exchange rates arises from international financing activities between subsidiaries, foreign currency denominated monetary assets and liabilities and transactions arising from international trade. The Company's objective is to preserve the U.S. Dollar value of foreign currency denominated cash flows and earnings. The Company monitors its collective foreign currency exposure and enters into foreign currency exchange forward and option contracts (foreign currency exchange contracts) with third parties, when necessary, to minimize the impact of changes in foreign currency exchange rates.

The Company has monetary assets and liabilities denominated in non-functional currencies. Prior to conversion into U.S. dollars, these assets and liabilities are remeasured at spot exchange rates in effect on the balance sheet date. The effects of changes in spot rates are recognized in earnings and included in Other (income) expense. We use foreign currency exchange contracts to hedge our foreign currency exposure. These contracts are marked-to-market with the resulting gains and losses recognized in earnings offsetting the gains and losses on the non-functional currency denominated monetary assets and liabilities being hedged. The Company uses foreign currency contracts to hedge forecasted sales and purchases, which are denominated in non-functional currencies. Changes in the forecasted non-functional currency cash flows due to movements in exchange rates are substantially offset by changes in the fair value of these foreign currency exchange contracts designated as hedges. Market value gains and losses on these contracts are recognized in earnings when the hedged transaction is recognized. As of December 31, 2020 and 2019, the Company held contracts with notional amounts of $16,123 million and $12,746 million to exchange foreign currencies, principally the U.S. Dollar, Euro, Canadian Dollar, British Pound, Swiss Franc, Mexican Peso, Chinese Renminbi, Indian Rupee, and Malaysian Ringgit.

The Company also designates certain foreign currency debt and derivative contracts as hedges against portions of its net investment in foreign operations. Gains or losses of the foreign currency debt and derivative contracts designated as net investment hedges are recorded in the same manner as foreign currency translation adjustments.

INTEREST RATE RISK MANAGEMENT

Financial instruments, including derivatives, expose the Company to market risk related to changes in interest rates. The Company uses a combination of financial instruments, including long-term, medium-term and short-term financing, variable-rate commercial paper, and interest rate swaps to convert the interest rate mix of our total debt portfolio and related overall cost of borrowing.

CREDIT RISK MANAGEMENT

The Company continues to monitor the creditworthiness of its counterparties to mitigate the risk of nonperformance. Financial instruments, including derivatives, expose the Company to counterparty credit risk. In addition, the Company grants credit terms to its customers in the normal course of business. The terms and conditions of our credit sales are designed to mitigate or eliminate concentrations of credit risk with any single customer. Our sales are not materially dependent on a single customer or a small group of customers.

DERIVATIVE AND HEDGING INSTRUMENTS

The following table summarizes the notional amounts and fair values of the Company’s outstanding derivatives by risk category and instrument type within the Consolidated Balance Sheet as of December 31, 2020 and 2019:

All derivative assets are presented in Other current assets or Other assets. All derivative liabilities are presented in Accrued liabilities or Other liabilities. As of December 31, 2020, cash collateral received that has not been offset against our derivatives of $34 million was recorded in Accrued liabilities and Other assets.

In addition to the foreign currency derivative contracts designated as net investment hedges, certain of the Company's foreign currency denominated debt instruments are designated as net investment hedges. The carrying value of those debt instruments designated as net investment hedges, which includes the adjustment for the foreign currency transaction gain or loss on those instruments, was $4,414 million and $6,882 million as of December 31, 2020 and 2019.

Interest rate swap agreements are designated as hedge relationships with gains or losses on the derivative recognized in Interest and other financial charges offsetting the gains and losses on the underlying debt being hedged. Gains and losses on interest rate swap agreements recognized in earnings were $169 million of income, $70 million of income and $37 million of expense for the years ended December 31, 2020, 2019 and 2018. Gains and losses are fully offset by losses and gains on the underlying debt being hedged.

The following table sets forth the amounts recorded on the Consolidated Balance Sheet related to cumulative basis adjustments for fair value hedges:


Line in the Consolidated Balance Sheet of Hedged Item	Carrying Amount of the Hedged Item				Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Item

Commitments and Contingencies

ENVIRONMENTAL MATTERS

The Company is subject to various federal, state, local and foreign government requirements relating to the protection of the environment. We believe that, as a general matter, our policies, practices and procedures are properly designed to prevent unreasonable risk of environmental damage and personal injury and that our handling, manufacture, use and disposal of hazardous substances are in accordance with environmental and safety laws and regulations. However, mainly because of past operations and operations of predecessor companies, we, like other companies engaged in similar businesses, have incurred remedial response and voluntary cleanup costs for site contamination and are a party to lawsuits and claims associated with environmental and safety matters, including past production of products containing hazardous substances. Additional lawsuits, claims and costs involving environmental matters are likely to continue to arise in the future.

With respect to environmental matters involving site contamination, the Company continually conducts studies, individually or jointly with other potentially responsible parties, to determine the feasibility of various remedial techniques. It is our policy to record appropriate liabilities for environmental matters when remedial efforts or damage claim payments are probable and the costs can be reasonably estimated. Such liabilities are based on our best estimate of the undiscounted future costs required to complete the remedial work. The recorded liabilities are adjusted periodically as remediation efforts progress or as additional technical, regulatory or legal information becomes available. Given the uncertainties regarding the status of laws, regulations, enforcement policies, the impact of other potentially responsible parties, technology and information related to individual sites, we do not believe it is possible to develop an estimate of the range of reasonably possible environmental loss in excess of our recorded liabilities. We expect to fund expenditures for these matters from operating cash flow. The timing of cash expenditures depends on a number of factors, including the timing of remedial investigations and feasibility studies, the timing of litigation and settlements of remediation liability, personal injury and property damage claims, regulatory approval of cleanup projects, remedial techniques to be utilized and agreements with other parties.

The following table summarizes information concerning the Company's recorded liabilities for environmental costs:


	Years Ended December 31,
	2020		2019		2018
Beginning of year	$	709	$	755	$	595
Accruals for environmental matters deemed probable and reasonably estimable	173		213		395
Environmental liability payments	(216)		(256)		(218)
Other	(6)		(3)		(17)
End of year	$	660	$	709	$	755

Environmental liabilities are included in the following balance sheet accounts:


	December 31,
	2020		2019
Accrued liabilities	$	225	$	222
Other liabilities	435		487
	$	660	$	709

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 Statement 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 Balance Sheet.

In conjunction with the 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 $140 million in both 2020 and 2019 and offset operating cash outflows incurred by the Company. On July 28, 2020, the Company and Resideo agreed to a second amendment of the indemnification and reimbursement agreement to extend the payment due date to October 30, 2020 for the reimbursement amount of $35 million (originally due on April 30, 2020). The Company had previously agreed to extend the payment date for such amount to July 30, 2020. On October 30, 2020, Resideo paid Honeywell the regularly scheduled reimbursement amount of $35 million due on that date as well as the deferred reimbursement amount of $35 million. 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 2020 and 2019 was $146 million and $109 million, respectively. As of December 31, 2020, Other Current Assets and Other Assets included $140 million and $451 million, respectively, for the short-term and long-term portion of the receivable amount due from Resideo under the indemnification and reimbursement agreement. As of December 31, 2019, Other Current Assets and Other Assets included $140 million and $445 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:

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. Such claims arise primarily from alleged occupational exposure to asbestos-containing refractory brick and mortar for high-temperature applications. NARCO ceased manufacturing these products in 1980 and ultimately 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) are the principal documents setting forth the structure of the Trust, establishing Honeywell’s evergreen funding obligations and the material operating rules for the Trust.

Per the TA, the Trust is eligible to receive cash dividends from Harbison-Walker International Inc. (HWI), the reorganized and renamed entity that emerged, fully operational, from the NARCO bankruptcy. The cash dividends are required to be used to pay 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. Dividends from HWI were exhausted during the fourth quarter of 2019 and there have been no further dividends from HWI to date.

The operating rules per the TDP include Honeywell’s audit rights and the 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. Once operational in 2014, the Trust began to receive, process and pay claims, at which point the Company began to assert its audit rights to review and monitor the claims processor’s adherence to the established requirements of the TDP. While doing so, the Company identified several issues with the way the Trust was adhering to the TDP and the Company continues to identify and dispute these matters as further claims are processed. Although the Company is attempting to resolve instances where it believes the Trust is not processing claims in accordance with the established TDP, the Company reserves the right to seek judicial intervention should it fail to resolve the disputed issues.

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 that were filed with the Trust upon becoming operative through December 31, 2017, the date by which these claims had to be filed or else be barred by the statute of limitations (subject to tolling exceptions in the TDP). 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 and the Company continued to update its original NARCO asbestos liability, as appropriate, using all available information.

With three years of sufficiently reliable claims data, the Company updated its estimate of the NARCO asbestos liability utilizing claims data from January 1, 2018 through December 31, 2020. The Company utilized an asbestos liability valuation specialist to support our preparation of the NARCO asbestos liability estimates. Our estimates, which involve significant management judgment, include consideration of multiple scenarios, including 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.

Our updated estimate of NARCO asbestos liability, which was consistent with the previously recorded NARCO liability estimate, was $779 million as of December 31, 2020. The liability reflects an estimate for the resolution of Annual Contribution Claims and Pre-Established Unliquidated Claims filed with the Trust, as well as unasserted Annual Contribution Claims and Pre-Established Unliquidated Claims. The NARCO asbestos liability excludes the annual operating expenses of the Trust which are expensed as they are incurred.

The Company's insurance receivable of $254 million as of December 31, 2020, corresponding to the estimated liability for asserted and unasserted NARCO asbestos claims, reflects coverage which reimburses Honeywell for portions of NARCO-related indemnity and defense costs and 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 conducts analyses to estimate 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:

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 and excludes the Company’s ongoing legal fees to defend such asbestos claims which will continue to be expensed as they are incurred. 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 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'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 MATTER

In conjunction with the Garrett spin-off, the Company entered into a binding indemnification and reimbursement agreement (Garrett Indemnity) with a Garrett subsidiary, pursuant to which Garrett’s subsidiary has an ongoing obligation to make cash payments to Honeywell in amounts equal to (i) 90% of Honeywell’s asbestos-related liability payments primarily related to the Bendix business in the United States, as well as certain environmental-related liability payments and accounts payable and non-United States asbestos-related liability payments, including the legal costs of defending and resolving such liabilities, less (ii) 90% of Honeywell’s net insurance receipts and, as may be applicable, certain other recoveries associated with such liabilities. The amount payable to Honeywell in respect of such liabilities arising in any given year is subject to a cap of approximately Euro 150 million (equivalent to $175 million at the time the Garrett Indemnity was entered into). The obligation under the terms of the Garrett Indemnity continues until the earlier of December 31, 2048, or December 31 of the third consecutive year during which the annual obligation is less than the Euro equivalent, at the fixed exchange rate at the time the indemnification and reimbursement agreement was entered into, of $25 million.

On June 12, 2020, the Company and Garrett entered into an amendment of the Garrett Indemnity in connection with Garrett’s amendment of its 2018 credit agreement. These amendments provided Garrett with temporary financial covenant relief with respect to the total leverage and interest coverage ratios, for a period that could extend to as late as June 30, 2022. Garrett’s payments to the Company under the Garrett Indemnity were deferred to the extent Garrett is (or to the extent such payments would cause Garrett to be) out of compliance with the original financial covenants and resume to the extent Garrett is in compliance with such original financial covenants. Any deferred amounts were to be paid to the extent Garrett was in compliance with such original financial covenants and had available capacity to make such payments pursuant to the terms of the Garrett Indemnity and its current credit agreement.

Reimbursements associated with the Garrett Indemnity are scheduled under the agreement to be collected from Garrett quarterly and offset operating cash outflows incurred by the Company. As a result of the extension referenced above and below, such amounts were $36 million in 2020 as compared with $152 million in 2019. As the Company records the accruals for matters covered by the Garrett Indemnity, a corresponding receivable from Garrett is recorded for 90% of that accrual as determined by the terms of the Garrett Indemnity.

In conjunction with the spin-off, Honeywell also entered into a binding tax matters agreement with Garrett and a Garrett subsidiary (the Tax Matters Agreement). The Tax Matters Agreement generally provides that Garrett is responsible and must indemnify Honeywell for all ordinary operating taxes, including income taxes, sales taxes, value-added taxes and payroll taxes, relating to Garrett for all periods, including periods prior to the spin-off, to the extent not paid prior to the spin-off date. In addition, among other items, as a result of the mandatory transition tax imposed by the U.S. Tax Cuts and Jobs Act, Garrett is required to make payments to Honeywell in the amount representing the net tax liability of Honeywell under the mandatory transition tax attributable to Garrett.

GARRETT LITIGATION AND BANKRUPTCY PROCEEDINGS

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 January 15, 2020, Garrett filed its complaint in the action, which asserted the same claims, and on March 5, 2020, we filed a Motion to Dismiss. On June 12, 2020, given the challenges of operating in the COVID-19 environment, Honeywell and Garrett entered into a litigation status agreement pursuant to which (i) the parties agreed to make good faith efforts to limit near-term litigation spend on this matter, and (ii) the Company agreed to extend both the $2 million payment owed by Garrett to the Company on May 1, 2020 under the Garrett Indemnity and the $18 million payment owed by Garrett to the Company on April 1, 2020 under the Tax Matters Agreement until December 31, 2020 (which amounts, as previously disclosed, had been deferred to May 31, 2020). On July 17, 2020, the Company received a notice from Garrett asserting that Honeywell has caused material breaches of the Tax Matters Agreement and that the Tax Matters Agreement is 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 23, 2020, Garrett moved the existing State Court litigation against Honeywell to the Bankruptcy Court. Honeywell again moved to dismiss all of Garrett’s claims on October 13, 2020. On November 2, 2020, Garrett filed a motion seeking to establish procedures to estimate the value of Honeywell’s claims. Honeywell objected to the motion. On November 18, 2020, the Bankruptcy Court did not rule on the motion to dismiss but suggested that two weeks be set aside in February 2021 for an evidentiary hearing to establish the actual allowed amount or net amount of Honeywell’s claim against Garrett. Honeywell and Garrett agreed to proceed with the estimation of Honeywell’s claims. We believe we have fully complied with our obligations under the Garrett Indemnity and the Tax Matters Agreement and that both agreements are valid and enforceable.

Garrett’s operations have and are expected to continue, without interruption, throughout the bankruptcy proceedings. Garrett initially proposed to sell its business while in bankruptcy, and entered into a Share and Asset Purchase Agreement, dated as of September 20, 2020, with KPS Capital Partners, LP (the Stalking Horse Agreement) and filed proposed bidding procedures for a marketing and sale process, auction and other procedures related to the proposed sale. In October 2020, Honeywell signed a coordination agreement with Oaktree Capital Management, L.P. (Oaktree) and Centerbridge Partners, L.P. (Centerbridge), which was subsequently signed by additional equity holders that, collectively with Honeywell, Centerbridge and Oaktree, represent approximately 58% of Garrett’s outstanding common stock and noteholders representing approximately 88% of the principal amount of Garrett’s outstanding senior notes (the Coordination Agreement). The Coordination Agreement and related term sheet set forth the terms of a proposed plan of reorganization (the Initial COH Proposal).

In October 2020, the Bankruptcy Court approved the bidding procedures and the Stalking Horse Agreement (as amended), and Garrett conducted a marketing and auction process through January 8, 2021. On January 11, 2021, after further revisions to the Initial COH Proposal, Garrett determined that the revised proposal (the Final COH Plan) was higher and better than all other proposals received and entered into a plan support agreement (the Plan Support Agreement), pursuant to which all parties agreed to pursue Bankruptcy Court confirmation of the Final COH Plan. On January 15, 2021, KPS Capital Partners, LP terminated the Stalking Horse Agreement with Garrett.

As set forth in the Plan Support Agreement, the Final COH Plan provides that, if it is confirmed by the Bankruptcy Court, Honeywell will receive from Garrett at the time of Garrett’s emergence from bankruptcy an initial payment of $375 million in cash and Series B Preferred Stock, which will provide for cash payments to Honeywell of $35 million in 2022 and $100 million per year from 2023 to 2030 (inclusive), subject to various put and call rights set forth therein. The initial cash payment, together with the Series B Preferred Stock, would be paid/issued in full and final satisfaction of Garrett’s obligations to Honeywell under the Garrett Indemnity and the Tax Matters Agreement. Upon Garrett’s emergence from bankruptcy, both agreements would be terminated, Honeywell and Garrett would mutually release each other from the claims asserted in all pending legal actions, and all pending litigation with Garrett would be resolved. In light of these developments, the hearing scheduled to estimate Honeywell’s claims and the adversary proceeding seeking to invalidate the Indemnity Agreement have been stayed and all related litigation suspended. If the Final COH Plan is confirmed by the Bankruptcy Court, both proceedings would be dismissed with prejudice on the effective date of the Final COH Plan.

We regularly review the aggregate carrying value of the receivable amounts due in connection with the Garrett Indemnity and the Tax Matters Agreement. Following Garrett’s bankruptcy filing on September 20, 2020, the Company reduced the aggregate carrying value of the receivable by $350 million to reflect the present value of

amounts owed to us over the full term of these agreements. Because Garrett is now a party to the Plan Support Agreement, we believe the present value of payments to Honeywell under the Final COH Plan, discounted at a rate reflective of the terms of the agreement, is an appropriate estimate of receivable amounts. On this basis, Honeywell recorded an additional adjustment of $92 million to lower the aggregate carrying value of the receivable amounts due in connection with the Garrett Indemnity and Tax Matters Agreement to $959 million as of December 31, 2020. Other Current Assets and Other Assets include $10 million and $949 million, respectively, for the short-term and long-term portion of the receivable amount due from the Garrett Indemnity and Tax Matters Agreement. As of December 31, 2019, Other Current Assets and Other Assets include $133 million and $1,188 million, respectively, for the short-term and long-term portion of the receivable amount due from the Garrett Indemnity and Tax Matters Agreement. For the year ended December 31, 2020, a non-cash charge of $509 million is recognized in Other (income) expense, which includes the adjustments to the carrying value of the receivable described above.

There can be no assurance that the Final COH Plan will be confirmed by the Bankruptcy Court or that Garrett will be able to substantially consummate the restructuring transactions contemplated in the Final COH Plan. The ultimate outcome of the bankruptcy process is uncertain. Depending on the transaction and/or plan of reorganization ultimately approved and confirmed by the Bankruptcy Court, the amount collected could differ from the receivable amounts currently recorded in our financial statements. There can be no assurance that recording an additional adjustment (positive or negative) against the remaining receivable amounts in whole or in part (together with a related statement of operations charge) will not be necessary in a future period or periods. Honeywell will continue to participate in the Bankruptcy Court proceedings in order to appropriately assess and enforce our rights in this matter. Should the Final COH Plan not be confirmed in the form currently contemplated, Honeywell intends to vigorously defend its rights to collect amounts due under the Garrett Indemnity and Tax Matters Agreement with Garrett.

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. 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 these 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. Included in these other matters is the following:

Honeywell v. United Auto Workers (UAW) et. al – In September 2011, the UAW and certain Honeywell retirees (Plaintiffs) filed a suit in the Eastern District of Michigan (the District Court) alleging that a series of Master Collective Bargaining Agreements (MCBAs) between Honeywell and the UAW provided the retirees with rights to lifetime, vested healthcare benefits that could never be changed or reduced. Plaintiffs alleged that Honeywell had violated those vested rights by implementing express limitations (CAPS) on the amount Honeywell contributed toward healthcare coverage for the retirees. Honeywell subsequently answered the UAW’s complaint and asserted counterclaims, including for breach of implied warranty.

Between 2014 and 2015, Honeywell began enforcing the CAPS against former employees. In response, the UAW and certain of the Plaintiffs filed a motion seeking a ruling that the MCBAs do not limit Honeywell’s obligation to contribute to healthcare coverage for those retirees.

On March 29, 2018, the District Court issued its opinion resolving all pending summary judgment motions, except for Honeywell’s counterclaim for breach of implied warranty, which has since been dismissed without prejudice.

In the opinion, the District Court held that the MCBAs do not promise retirees vested, lifetime benefits that survive expiration of the MCBAs. Based on this ruling, Honeywell terminated the retirees healthcare coverage benefits altogether as of July 31, 2018. In response, the UAW filed a motion to enjoin Honeywell from completely terminating coverage as of July 31, 2018, arguing that the CAPS themselves are vested and that Honeywell must continue to provide retiree medical benefits at the capped level. On July 28, 2018, the District Court denied the UAW’s motion and entered a final judgment consistent with its March 2018 ruling. The UAW appealed this decision to the Sixth Circuit Court of Appeals.

In the March 2018 opinion, the District Court also held that Honeywell is obligated under the MCBAs to pay the “full premium” for retiree healthcare rather than the capped amount. Based on this ruling, Honeywell would be required

to pay monetary damages to retirees for any past years in which Honeywell paid less than the “full premium” of their healthcare coverage. Such damages would be limited, depending on the retiree group, to a two to three-year period ending when the 2017 MCBA expired, and Honeywell would have no ongoing obligation to continue funding healthcare coverage for subsequent periods. Honeywell appealed the District Court’s ruling on this “full premium” damages issue.

On April 3, 2020, the Sixth Circuit Court of Appeals issued an opinion ruling for Honeywell in all respects. The Court of Appeals affirmed the District Court's ruling that the MCBAs do not promise retirees vested, lifetime benefits that survive expiration of the MCBAs. In addition, the Court of Appeals reversed the District Court's ruling that Honeywell was obligated under the MCBAs to pay the "full premium" for retiree healthcare, rather than the capped amount. As a result of these rulings, Honeywell is not required to pay any monetary damages to the Plaintiffs.

Plaintiffs sought rehearing en banc from the Sixth Circuit Court of Appeals, which petition was denied. Plaintiffs failed to timely appeal the Sixth Circuit's ruling to the Supreme Court of the United States. Accordingly, as of October 8, 2020, the case was fully resolved.

Petrobras and Unaoil – We are cooperating with certain investigations by the U.S. Department of Justice (DOJ), the SEC and 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). The investigations are focused on compliance with the U.S. Foreign Corrupt Practices Act and similar Brazilian laws, 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 engagement of Unaoil S.A.M. in Algeria. We are cooperating with the authorities in each of the above matters. While we cannot predict the outcome of these matters, based on the facts currently known to us, we do not anticipate that these matters will have a material adverse effect on our financial condition, results of operations, or cash flows.

Given the uncertainty inherent in litigation and investigations (including the specific matters referenced above), we do not believe it is possible to develop estimates of reasonably possible loss in excess of current accruals for these matters (other than as specifically set forth above). Considering our past experience and existing accruals, we do not expect the outcome of these matters, either individually or in the aggregate, to have a material adverse effect on our consolidated financial position. Because most contingencies are resolved over long periods of time, potential liabilities are subject to change due to new developments, changes in settlement strategy or the impact of evidentiary requirements, which could cause us to pay damage awards or settlements (or become subject to equitable remedies) that could have a material adverse effect on our Consolidated Results of Operations or operating cash flows in the periods recognized or paid.

WARRANTIES AND GUARANTEES

In the normal course of business, the Company issues product warranties and product performance guarantees. We accrue for the estimated cost of product warranties and performance guarantees based on contract terms and historical experience at the time of sale. Adjustments to initial obligations for warranties and guarantees are made as changes to the obligations become reasonably estimable. The following table summarizes information concerning our recorded obligations for product warranties and product performance guarantees.

Segment Reporting [Abstract]

Segment Financial Data

Honeywell globally manages its business operations through four reportable operating segments. Segment information is consistent with how management reviews the businesses, makes investing and resource allocation decisions and assesses operating performance.

Honeywell’s senior management evaluates segment performance based on segment profit. Each segment’s profit is measured as segment income (loss) before taxes excluding general corporate unallocated expense, interest and other financial charges, stock compensation expense, pension and other postretirement income (expense), repositioning and other charges, and other items within Other (income) expense.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Dec. 31, 2020
Accounting Policies [Abstract]
Accounting Principles	ACCOUNTING PRINCIPLES The financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America. The following is a description of Honeywell’s significant accounting policies.
Principles of Consolidation	PRINCIPLES OF CONSOLIDATION The Consolidated Financial Statements include the accounts of Honeywell International Inc. and all of its subsidiaries and entities in which a controlling interest is maintained. Our consolidation policy requires equity investments that we exercise significant influence over but do not control the investee and are not the primary beneficiary of the investee’s activities to be accounted for using the equity method. Investments through which we are not able to exercise significant influence over the investee and which we do not have readily determinable fair values are accounted for under the cost method. All intercompany transactions and balances are eliminated in consolidation.
Reclassifications	RECLASSIFICATIONS Certain prior year amounts have been reclassified to conform to the current year presentation.
Recent Accounting Pronouncements	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 statement of operations, balance sheet and cash flows (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 does 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 accounted 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.
Research and Development	RESEARCH AND DEVELOPMENT Research and development costs for projects are expensed as incurred, unless these costs relate to contracts with customers where we receive reimbursements. Amounts expensed as incurred for Company-sponsored research and development projects are included in Cost of products and services sold and were $1,334 million, $1,556 million and $1,809 million for the years ended December 31, 2020, 2019 and 2018. Costs related to contracts with customers for customer-sponsored research and development projects are included as a contract cost and included in Cost of products and services sold when revenue from such contracts is recognized, consistent with our sales recognition policies. This revenue was $1,200 million, $1,079 million and $1,069 million for the years ended December 31, 2020, 2019 and 2018.
Cash And Cash Equivalents	CASH AND CASH EQUIVALENTS Cash and cash equivalents include cash on hand and highly liquid investments having an original maturity of three months or less.
Property, Plant and Equipment	PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are recorded at cost, including any asset retirement obligations, less accumulated depreciation. For financial reporting, the straight-line method of depreciation is used over the estimated useful lives of 10 to 50 years for buildings and improvements and 2 to 16 years for machinery and equipment. Recognition of the fair value of obligations associated with the retirement of tangible long-lived assets is required when there is a legal obligation to incur such costs. Upon initial recognition of a liability, the cost is capitalized as part of the related long-lived asset and depreciated over the corresponding asset’s useful life.
Goodwill and Indefinite-Lived Intangible Assets	GOODWILL AND INDEFINITE-LIVED INTANGIBLE ASSETSGoodwill and indefinite-lived intangible assets are subject to impairment testing annually as of March 31, and whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. This testing compares carrying values to fair values and, when appropriate, the carrying value of these assets is reduced to fair value. We completed our annual goodwill impairment test as of March 31, 2020 and determined that there was no impairment as of that date. In addition, due to the economic impact of COVID-19, we updated our assessment as of June 30, 2020, and determined there was no impairment. We are not aware of any additional triggering events.
Finite-Lived Intangible Assets	FINITE-LIVED INTANGIBLE ASSETS Other intangible assets with determinable lives consist of customer lists, technology, patents and trademarks and other intangibles and are amortized over their estimated useful lives, ranging from 2 to 24 years.
Foreign Currency Translation	FOREIGN CURRENCY TRANSLATION Assets and liabilities of subsidiaries operating outside the United States with a functional currency other than U.S. Dollars are translated into U.S. Dollars using year-end exchange rates. Sales, costs and expenses are translated at the average exchange rates in effect during the year. Foreign currency translation gains and losses are included as a component of Accumulated other comprehensive income (loss). For subsidiaries operating in highly inflationary environments, inventories and property, plant and equipment, including related expenses, are remeasured at the exchange rate in effect on the date the assets were acquired, while monetary assets and liabilities are remeasured at year-end exchange rates. Remeasurement adjustments for these subsidiaries are included in earnings.
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS All derivative financial instruments are recorded on the balance sheet as assets or liabilities and measured at fair value. For derivatives designated as hedges of the fair value of assets or liabilities, the changes in fair values of both the derivatives and the hedged items are recorded in current earnings. For derivatives designated as cash flow hedges, the changes in fair value of the derivatives are recorded in Accumulated other comprehensive income (loss) and subsequently recognized in earnings when the hedged items impact earnings. Derivative financial instruments designated as hedges must be designated and effective as a hedge of the identified risk exposure at the inception of the contract. Changes in fair value of the derivative contract must be highly correlated with changes in fair value of the underlying hedged item at inception and over the life of the hedge contract. Cash flows of such derivative financial instruments are classified consistent with the underlying hedged item. We elected to exclude the time value of the derivatives (i.e., the forward points) from the assessment of hedge effectiveness and recognize the initial value of the excluded component in earnings using the amortization approach. For derivative instruments that are designated and qualify as a net investment hedge, the gain or loss is reported as a component of Other comprehensive income (loss) and recorded in Accumulated other comprehensive income (loss). The gain or loss will be subsequently reclassified into net earnings when the hedged net investment is either sold or substantially liquidated.
Leases	LEASES At the inception of a contract, the Company assesses whether the contract is, or contains, a lease. The assessment is based on (1) whether the contract involves the use of a distinct identified asset, (2) whether the Company obtains the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether the Company has the right to direct the use of the asset. All significant lease arrangements are generally recognized at lease commencement. Operating lease right-of-use (ROU) assets and lease liabilities are recognized at commencement. An ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (short-term leases), and we recognize lease expense for these leases as incurred over the lease term. ROU assets represent our right to use an underlying asset during the reasonably certain lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Lease payments may be fixed or variable, however, only fixed payments or in-substance fixed payments are included in determining the lease liability. Variable lease payments are recognized in operating expenses in the period in which the obligation for those payments are incurred. The operating lease ROU asset also includes any lease payments related to initial direct cost and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components, which are generally accounted for separately. The Company primarily uses our incremental borrowing rate, which is based on the information available at the lease commencement date, in determining the present value of the lease payments. In determining the borrowing rate, we consider the lease term, secured incremental borrowing rate, and for leases denominated in a currency different than U.S. dollar, the collateralized borrowing rate in the foreign currency using the U.S. dollar and foreign currency swap spread, when available.
Pension Benefits	PENSION BENEFITS The Company presents net periodic pensions costs by disaggregating the service cost component of such costs and reports those costs in the same line item or items in the Consolidated Statement of Operations as other compensation costs arising from services rendered by the pertinent employees during the period. The other non-service components of such costs are required to be presented separately from the service cost component. The Company records the service cost component of Pension ongoing (income) expense in Costs of products and services sold and Selling, general and administrative expenses. The remaining components of costs within Pension ongoing (income) expense, primarily interest costs and assumed return on plan assets, are recorded in Other (income) expense. We recognize net actuarial gains or losses in excess of 10% of the greater of the fair value of plan assets or the plan's projected benefit obligation (the corridor) annually in the fourth quarter each year (MTM Adjustment). The MTM Adjustment is also reported in Other (income) expense.
Sales Recognition	SALES RECOGNITION Product and service sales are recognized when or as the Company transfers control of the promised products or services to its customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Service sales, principally representing repair, maintenance and engineering activities, are recognized over the contractual period or as services are rendered. Sales under long-term contracts with performance obligations satisfied over time are recognized using either an input or output method. We recognize revenue over time as we perform on these contracts because of the continuous transfer of control to the customer. With control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. We generally use the cost-to-cost input method of progress for our contracts because it best depicts the transfer of control to the customer that occurs as we incur costs. Under the cost-to-cost method, the extent of progress towards completion is measured based on the proportion of costs incurred to date to the total estimated costs at completion of the performance obligation. We review our cost estimates on significant contracts on a periodic basis, or when circumstances change and warrant a modification to a previous estimate. Cost estimates are largely based on negotiated or estimated purchase contract terms, historical performance trends and other economic projections. Significant factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, asset utilization, and anticipated labor agreements. Provisions for anticipated losses on long-term contracts are recorded in full when such losses become evident, to the extent required. The customer funding for costs incurred for nonrecurring engineering and development activities of our products under agreements with commercial customers is deferred and subsequently recognized as revenue as products are delivered to the customers. Additionally, expenses incurred, up to the customer agreed funded amount, are deferred as an asset and recognized as cost of sales when products are delivered to the customer. The deferred customer funding and costs result in recognition of deferred costs (asset) and deferred revenue (liability) on our Consolidated Balance Sheet. Capitalized contract fulfillment costs were approximately $1.3 billion and $1 billion as of December 31, 2020 and 2019. The amounts recognized as Cost of products and services sold were approximately $0.1 billion for the years ended December 31, 2020, 2019 and 2018. Revenues for our mechanical service programs are recognized as performance obligations that are satisfied over time, with recognition reflecting a series of distinct services using the output method. The terms of a contract or the historical business practice can give rise to variable consideration due to, but not limited to, cash-based incentives, rebates, performance awards, or credits. We estimate variable consideration at the most likely amount we will receive from customers. We include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for such transaction will not occur, or when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us.
Stock-Based Compensation Plans	STOCK-BASED COMPENSATION PLANS The principal awards issued under our stock-based compensation plans, which are described in Note 16 Stock-Based Compensation Plans, are non-qualified stock options and restricted stock units. The cost for such awards is measured at the grant date based on the fair value of the award. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods (generally the vesting period of the equity award) and is included in Selling, general and administrative expenses. Forfeitures are estimated at the time of grant to recognize expense for those awards that are expected to vest and are based on our historical forfeiture rates.
Income Taxes	INCOME TAXES Significant judgment is required in evaluating tax positions. We establish reserves for income taxes when, despite the belief that tax positions are fully supportable, there remain certain positions that do not meet the minimum recognition threshold. The approach for evaluating certain and uncertain tax positions is defined by the authoritative guidance which determines when a tax position is more likely than not to be sustained upon examination by the applicable taxing authority. In the normal course of business, the Company and its subsidiaries are examined by various federal, state and foreign tax authorities. We regularly assess the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of our provision for income taxes. We continually assess the likelihood and amount of potential adjustments and adjust the income tax provision, the current tax liability and deferred taxes in the period in which the facts that give rise to a change in estimate become known. During 2020, the Company revised the disclosure of deferred tax assets and deferred tax liabilities in Note 5 Income Taxes as of December 31, 2019, to present separately the deferred tax liability for Right-of-use assets of $159 million and the deferred tax asset for Lease liabilities of $167 million, which were previously reported net within the deferred tax liability for Property, plant and equipment. This had no other impact to our Consolidated Financial Statements. For additional information, see Note 5 Income Taxes.
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding and all dilutive potential common shares outstanding.
Environmental	ENVIRONMENTAL The Company accrues costs related to environmental matters when it is probable that it has incurred a liability related to a contaminated site and the amount can be reasonably estimated. For additional information, see Note 20 Commitments and Contingencies.
Asbestos Related Liabilities and Insurance Recoveries	ASBESTOS RELATED LIABILITIES AND INSURANCE RECOVERIES The Company recognizes a liability for any asbestos related contingency that is probable of occurrence and reasonably estimable. In connection with the recognition of liabilities for asbestos related matters, we record asbestos related insurance recoveries that are deemed probable. For additional information, see Note 20 Commitments and Contingencies.
Reimbursement Receivables [Policy Text Block]	REIMBURSEMENT RECEIVABLES In conjunction with the Garrett and Resideo spin-offs, the Company entered into reimbursement agreements under which Honeywell receives cash payments as reimbursement primarily for asbestos related liability payments related to the Bendix business in the U.S. (Garrett) and for net spending for environmental matters at certain sites as defined in the agreement (Resideo). Accordingly, the Company recorded receivables based on estimates of the underlying reimbursable Honeywell asbestos and environmental spend, and we monitor the recoverability of such receivables, which are subject to the terms of applicable credit agreements and general ability to pay. For Garrett, the Company established an allowance based on the developments associated with Garrett's Chapter 11 bankruptcy filing. See Note 20 Commitments and Contingencies for a discussion of the recognition and measurement of our reimbursement receivables, including the allowance established for Garrett.

Retirement Benefits, Description [Abstract]

Pension and Other Postretirement Benefits

The Company sponsors a number of both funded and unfunded U.S. and non-U.S. defined benefit pension plans. Pension benefits for many of our U.S. employees are provided through non-contributory, qualified and non-qualified defined benefit plans. All non-union hourly and salaried employees joining Honeywell for the first time after December 31, 2012, are not eligible to participate in Honeywell’s U.S. defined benefit pension plans. We also sponsor defined benefit pension plans which cover non-U.S. employees who are not U.S. citizens, in certain jurisdictions, principally the UK, Netherlands, Germany, and Canada. Other pension plans outside of the U.S. are not material to the Company either individually or in the aggregate.

The Company also sponsors postretirement benefit plans that provide health care benefits and life insurance coverage mainly to U.S. eligible retirees. None of Honeywell’s U.S. employees are eligible for a retiree medical subsidy from the Company. In addition, the vast majority of Honeywell’s U.S. retirees either have no Company subsidy or have a fixed-dollar subsidy amount. This significantly limits our exposure to the impact of future health care cost increases. The retiree medical and life insurance plans are not funded. Claims and expenses are paid from our cash flows from operations.

The following tables summarize the balance sheet impact, including the benefit obligations, assets and funded status associated with the Company's significant pension and other postretirement benefit plans.

Major actuarial assumptions used in determining the benefit obligations and net periodic benefit (income) cost for our significant benefit plans are presented in the following table as weighted averages.


	Pension Benefits
	U.S. Plans						Non-U.S. Plans
	2020		2019		2018		2020		2019		2018
Actuarial assumptions used to determine benefit obligations as of December 31:
Discount rate	2.50	%	3.22	%	4.35	%	1.23	%	1.81	%	2.63	%
Expected annual rate of compensation increase	3.25	%	3.25	%	3.25	%	2.43	%	2.47	%	2.46	%
Actuarial assumptions used to determine net periodic benefit (income) cost for years ended December 31:
Discount rate—benefit obligation	3.22	%	4.35	%	3.68	%	1.81	%	2.63	%	2.36	%
Discount rate—service cost	3.33	%	4.47	%	3.77	%	1.48	%	2.26	%	2.20	%
Discount rate—interest cost	2.76	%	3.94	%	3.27	%	1.56	%	2.34	%	2.08	%
Expected rate of return on plan assets	6.15	%	6.75	%	7.75	%	4.66	%	5.14	%	6.23	%
Expected annual rate of compensation increase	3.25	%	3.25	%	4.50	%	2.47	%	2.46	%	2.49	%


	Other Postretirement Benefits
	2020		2019		2018
Actuarial assumptions used to determine benefit obligations as of December 31:
Discount rate	2.20	%	3.03	%	4.07	%
Actuarial assumptions used to determine net periodic benefit cost for years ended December 31:
Discount rate(1)	2.36	%	4.07	%	3.39	%

(1) Discount rate was 3.03% for January 1, 2020 through September 30, 2020. The rate was changed to 2.36% for the remainder of 2020 due to a Plan remeasurement as of October 1, 2020.

The discount rate for the Company's U.S. pension and other postretirement benefits plans reflects the current rate at which the associated liabilities could be settled at the measurement date of December 31. To determine discount rates for our U.S. pension and other postretirement benefit plans, we use a modeling process that involves matching the expected cash outflows of our benefit plans to a yield curve constructed from a portfolio of high quality, fixed-income debt instruments. We use the single weighted-average yield of this hypothetical portfolio as a discount rate benchmark. We utilize a full yield curve approach in the estimation of the service and interest cost components of net periodic pension benefit (income) for our significant pension plans. This approach applies the specific spot rates along the yield curve used in the determination of the pension benefit obligation to their underlying projected cash flows and provides a more precise measurement of service and interest costs by improving the correlation between projected cash flows and their corresponding spot rates. For our U.S. pension plans, the single weighted average spot rates used to determine service and interest costs for 2021 are 2.67% and 1.76%. The discount rate used to determine the other postretirement benefit obligation is lower principally due to a shorter expected duration of other postretirement plan obligations as compared to pension plan obligations.

The Company plans to use an expected rate of return on U.S. plan assets of 6.15% for 2021, matching the 6.15% assumption used for 2020. Our asset return assumption is based on historical plan asset returns over varying long-term periods combined with current market conditions and broad asset mix considerations with a focus on long-term trends rather than short-term market conditions. We review the expected rate of return on an annual basis and revise it as appropriate.

For non-U.S. benefit plans actuarial assumptions reflect economic and market factors relevant to each country.

PENSION BENEFITS

The following amounts relate to the Company's significant pension plans with accumulated benefit obligations exceeding the fair value of plan assets:


	December 31,
	U.S. Plans				Non-U.S. Plans
	2020		2019		2020		2019
Projected benefit obligation	$	353	$	357	$	2,116	$	1,018
Accumulated benefit obligation	$	341	$	347	$	2,042	$	973
Fair value of plan assets	$	—	$	—	$	1,208	$	233

The accumulated benefit obligation for the Company's U.S. defined benefit pension plans was $17.9 billion and $17.2 billion and for our Non-U.S. defined benefit pension plans was $7.6 billion and $6.8 billion at December 31, 2020 and 2019.

The Company's asset investment strategy for our U.S. pension plans focuses on maintaining a diversified portfolio using various asset classes in order to achieve our long-term investment objectives on a risk adjusted basis. During 2020, we continued to employ a de-risking strategy which increases the matching characteristics of our assets relative to our obligation. Our long-term target allocations are as follows: 55%-70% fixed income securities and cash, 25%-40% equity securities, 5%-10% real estate investments, and 10%-20% other types of investments. Equity securities include publicly-traded stock of companies located both inside and outside the United States. Fixed income securities include corporate bonds of companies from diversified industries, mortgage-backed securities, and U.S. Treasuries. Real estate investments include direct investments in commercial properties and investments in real estate funds. Other types of investments include investments in private equity and hedge funds that follow several different strategies. We review our assets on a regular basis to ensure that we are within the targeted asset allocation ranges and, if necessary, asset balances are adjusted back within target allocations.

The Company's non-U.S. pension assets are typically managed by decentralized fiduciary committees with the Honeywell Corporate Investments group providing funding and investment guidance. Our non-U.S. investment policies are different for each country as local regulations, funding requirements, and financial and tax considerations are part of the funding and investment allocation process in each country.

In accordance with ASU 2015-07, “Fair Value Measurement (Topic 820)”, certain investments that are measured at fair value using the net asset value (NAV) per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in the following tables are intended to permit reconciliation of the fair value hierarchy to the amounts presented for the total pension benefits plan assets.

The fair values of both the Company's U.S. and non-U.S. pension plans assets by asset category are as follows:

The Company enters into futures contracts to gain exposure to certain markets. Sufficient cash or cash equivalents are held by our pension plans to cover the notional value of the futures contracts. At December 31, 2020 and 2019, our U.S. plans had contracts with notional amounts of $3,673 million and $4,463 million. At December 31, 2020 and 2019, our non-U.S. plans had contracts with notional amounts of $564 million and $479 million. In both our U.S. and non-U.S. pension plans, the notional derivative exposure is related to outstanding equity and fixed income futures contracts.

Common stocks, preferred stocks, real estate investment trusts, and short-term investments are valued at the closing price reported in the active market in which the individual securities are traded. Corporate bonds, mortgages/asset-backed securities, and government securities are valued either by using pricing models, bids provided by brokers or dealers, quoted prices of securities with similar characteristics or discounted cash flows and as such include adjustments for certain risks that may not be observable such as credit and liquidity risks. Certain securities are held in collective trust funds which are valued using net asset values provided by the administrators of the funds. Investments in private equity, debt, real estate and hedge funds and direct private investments are valued at estimated fair value based on quarterly financial information received from the investment advisor and/or general partner. Investments in real estate properties are valued on a quarterly basis using the income approach. Valuation estimates are periodically supplemented by third party appraisals. The insurance buy-in contracts represent policies held by the Honeywell UK Pension Scheme, whereby the cost of providing pension benefits to plan participants is funded by the policies. The cash flows from the policies are intended to match the pension benefits. The fair value of these policies is based on an estimate of the policies' exit price.

The Company's funding policy for qualified defined benefit pension plans is to contribute amounts at least sufficient to satisfy regulatory funding standards. In 2020, 2019, and 2018, we were not required to make contributions to our U.S. pension plans and no contributions were made. We are not required to make any contributions to our U.S. pension plans in 2021. In 2020, contributions of $109 million were made to our non-U.S. pension plans to satisfy regulatory funding requirements. In 2021, we expect to make contributions of cash and/or marketable securities of approximately $85 million to our non-U.S. pension plans to satisfy regulatory funding standards. Contributions for both our U.S. and non-U.S. pension plans do not reflect benefits paid directly from Company assets.

Benefit payments, including amounts to be paid from Company assets, and reflecting expected future service, as appropriate, are expected to be paid as follows:

(2016 Directors Plan) were both approved by the shareowners at the Annual Meeting of Shareowners effective on April 25, 2016. At December 31, 2020, there were 34,104,522, and 832,309 shares of Honeywell common stock available for future grants under terms of the 2016 Plan and 2016 Directors Plan, respectively.

STOCK OPTIONS

The exercise price, term and other conditions applicable to each option granted under the Company's stock plans are generally determined by the Management Development and Compensation Committee of the Board of Directors. The exercise price of stock options is set on the grant date and may not be less than the fair market value per share of our stock on that date. The fair value is recognized as an expense over the employee’s requisite service period (generally the vesting period of the award). Options generally vest over a four-year period and expire after ten years.

The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. Expected volatility is based on implied volatilities from traded options on our common stock and historical volatility of our common stock. We used a Monte Carlo simulation model to derive an expected term which represents an estimate of the time options are expected to remain outstanding. Such model uses historical data to estimate option exercise activity and post-vest termination behavior. The risk-free rate for periods within the contractual life of the option is based on the U.S. treasury yield curve in effect at the time of grant.

RESTRICTED STOCK UNITS

Restricted stock unit (RSU) awards entitle the holder to receive one share of common stock for each unit when the units vest. RSUs are issued to certain key employees and directors as compensation at fair market value at the date of grant. RSUs generally become fully vested over periods ranging from three to six years and are payable in Honeywell common stock upon vesting.

The following table summarizes information about RSU activity for the three years ended December 31, 2020:

Fair Value Disclosures [Abstract]

Financial Instruments and Fair Value Measures

FAIR VALUE MEASUREMENTS

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 that were accounted for at fair value on a recurring basis as of December 31, 2020 and 2019:


	December 31,
	2020		2019
Assets:
Foreign currency exchange contracts	$	202	$	291
Available for sale investments	1,118		1,523
Interest rate swap agreements	194		38
Cross currency swap agreements	—		51
Liabilities:
Foreign currency exchange contracts	$	150	$	21
Interest rate swap agreements	—		13
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 and are valued using published prices based on observable market data. As such, these investments are classified within level 2. The Company also holds available for sale investments in U.S. government and corporate debt securities 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 contained in the Consolidated Balance Sheet approximates fair value.

The following table sets forth the Company’s financial assets and liabilities that were not carried at fair value:


	December 31, 2020				December 31, 2019
	Carrying Value		Fair Value		Carrying Value		Fair Value
Assets:
Long-term receivables	$	137	$	132	$	129	$	127

The Company recognizes revenue arising from performance obligations outlined in contracts with its customers that are satisfied at a point in time and over time. The disaggregation of our revenue based off timing of recognition is as follows:


	Years Ended December 31,

Net sales	100	%	100	%	100	%

CONTRACT BALANCES

The Company records progress on satisfying performance obligations under contracts with customers and the related billings and cash collections are recorded 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. Those assets are recognized when the revenue associated with the contract is recognized prior to billing and derecognized when billed in accordance with the terms of the contract. Contract liabilities are recorded when customers remit contractual cash payments in advance of us satisfying performance obligations under contractual arrangements, including those with performance obligations to be satisfied over a period of time. Contract liabilities are derecognized 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:


	2020		2019
Contract assets—January 1	$	1,602	$	1,548
Contract assets—December 31	1,618		1,602
Change in contract assets—increase (decrease)	$	16	$	54
Contract liabilities—January 1	$	(3,501)	$	(3,378)
Contract liabilities—December 31	(4,033)		(3,501)
Change in contract liabilities—(increase) decrease	$	(532)	$	(123)
Net change	$	(516)	$	(69)

The net change in 2020 and 2019 was primarily driven by the receipt of advance payments from customers exceeding recognition of revenue as performance obligations were satisfied prior to billing. For the years ended December 31, 2020 and 2019, the Company recognized revenue of $1,709 million and $1,543 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 for goods or services and 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 our 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 our 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 our 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, we allocate 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 stand alone 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:


	December 31, 2020
Aerospace	$	9,493
Honeywell Building Technologies	5,924
Performance Materials and Technologies	6,704
Safety and Productivity Solutions	4,255
	$	26,376

Performance obligations recognized as of December 31, 2020 will be satisfied over the course of future periods. Our 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 55% and 45%, 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 our 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 has 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.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Dec. 31, 2020
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	ACCOUNTING PRINCIPLES The financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America. The following is a description of Honeywell’s significant accounting policies. PRINCIPLES OF CONSOLIDATION The Consolidated Financial Statements include the accounts of Honeywell International Inc. and all of its subsidiaries and entities in which a controlling interest is maintained. Our consolidation policy requires equity investments that we exercise significant influence over but do not control the investee and are not the primary beneficiary of the investee’s activities to be accounted for using the equity method. Investments through which we are not able to exercise significant influence over the investee and which we do not have readily determinable fair values are accounted for under the cost method. All intercompany transactions and balances are eliminated in consolidation. 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 statement of operations, balance sheet and cash flows (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 does 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 accounted 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. RESEARCH AND DEVELOPMENT Research and development costs for projects are expensed as incurred, unless these costs relate to contracts with customers where we receive reimbursements. Amounts expensed as incurred for Company-sponsored research and development projects are included in Cost of products and services sold and were $1,334 million, $1,556 million and $1,809 million for the years ended December 31, 2020, 2019 and 2018. Costs related to contracts with customers for customer-sponsored research and development projects are included as a contract cost and included in Cost of products and services sold when revenue from such contracts is recognized, consistent with our sales recognition policies. This revenue was $1,200 million, $1,079 million and $1,069 million for the years ended December 31, 2020, 2019 and 2018. CASH AND CASH EQUIVALENTS Cash and cash equivalents include cash on hand and highly liquid investments having an original maturity of three months or less. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are recorded at cost, including any asset retirement obligations, less accumulated depreciation. For financial reporting, the straight-line method of depreciation is used over the estimated useful lives of 10 to 50 years for buildings and improvements and 2 to 16 years for machinery and equipment. Recognition of the fair value of obligations associated with the retirement of tangible long-lived assets is required when there is a legal obligation to incur such costs. Upon initial recognition of a liability, the cost is capitalized as part of the related long-lived asset and depreciated over the corresponding asset’s useful life. GOODWILL AND INDEFINITE-LIVED INTANGIBLE ASSETS Goodwill and indefinite-lived intangible assets are subject to impairment testing annually as of March 31, and whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. This testing compares carrying values to fair values and, when appropriate, the carrying value of these assets is reduced to fair value. We completed our annual goodwill impairment test as of March 31, 2020 and determined that there was no impairment as of that date. In addition, due to the economic impact of COVID-19, we updated our assessment as of June 30, 2020, and determined there was no impairment. We are not aware of any additional triggering events. FINITE-LIVED INTANGIBLE ASSETS Other intangible assets with determinable lives consist of customer lists, technology, patents and trademarks and other intangibles and are amortized over their estimated useful lives, ranging from 2 to 24 years. FOREIGN CURRENCY TRANSLATION Assets and liabilities of subsidiaries operating outside the United States with a functional currency other than U.S. Dollars are translated into U.S. Dollars using year-end exchange rates. Sales, costs and expenses are translated at the average exchange rates in effect during the year. Foreign currency translation gains and losses are included as a component of Accumulated other comprehensive income (loss). For subsidiaries operating in highly inflationary environments, inventories and property, plant and equipment, including related expenses, are remeasured at the exchange rate in effect on the date the assets were acquired, while monetary assets and liabilities are remeasured at year-end exchange rates. Remeasurement adjustments for these subsidiaries are included in earnings. DERIVATIVE FINANCIAL INSTRUMENTS All derivative financial instruments are recorded on the balance sheet as assets or liabilities and measured at fair value. For derivatives designated as hedges of the fair value of assets or liabilities, the changes in fair values of both the derivatives and the hedged items are recorded in current earnings. For derivatives designated as cash flow hedges, the changes in fair value of the derivatives are recorded in Accumulated other comprehensive income (loss) and subsequently recognized in earnings when the hedged items impact earnings. Derivative financial instruments designated as hedges must be designated and effective as a hedge of the identified risk exposure at the inception of the contract. Changes in fair value of the derivative contract must be highly correlated with changes in fair value of the underlying hedged item at inception and over the life of the hedge contract. Cash flows of such derivative financial instruments are classified consistent with the underlying hedged item. We elected to exclude the time value of the derivatives (i.e., the forward points) from the assessment of hedge effectiveness and recognize the initial value of the excluded component in earnings using the amortization approach. For derivative instruments that are designated and qualify as a net investment hedge, the gain or loss is reported as a component of Other comprehensive income (loss) and recorded in Accumulated other comprehensive income (loss). The gain or loss will be subsequently reclassified into net earnings when the hedged net investment is either sold or substantially liquidated. LEASES At the inception of a contract, the Company assesses whether the contract is, or contains, a lease. The assessment is based on (1) whether the contract involves the use of a distinct identified asset, (2) whether the Company obtains the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether the Company has the right to direct the use of the asset. All significant lease arrangements are generally recognized at lease commencement. Operating lease right-of-use (ROU) assets and lease liabilities are recognized at commencement. An ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (short-term leases), and we recognize lease expense for these leases as incurred over the lease term. ROU assets represent our right to use an underlying asset during the reasonably certain lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Lease payments may be fixed or variable, however, only fixed payments or in-substance fixed payments are included in determining the lease liability. Variable lease payments are recognized in operating expenses in the period in which the obligation for those payments are incurred. The operating lease ROU asset also includes any lease payments related to initial direct cost and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components, which are generally accounted for separately. The Company primarily uses our incremental borrowing rate, which is based on the information available at the lease commencement date, in determining the present value of the lease payments. In determining the borrowing rate, we consider the lease term, secured incremental borrowing rate, and for leases denominated in a currency different than U.S. dollar, the collateralized borrowing rate in the foreign currency using the U.S. dollar and foreign currency swap spread, when available. PENSION BENEFITS The Company presents net periodic pensions costs by disaggregating the service cost component of such costs and reports those costs in the same line item or items in the Consolidated Statement of Operations as other compensation costs arising from services rendered by the pertinent employees during the period. The other non-service components of such costs are required to be presented separately from the service cost component. The Company records the service cost component of Pension ongoing (income) expense in Costs of products and services sold and Selling, general and administrative expenses. The remaining components of costs within Pension ongoing (income) expense, primarily interest costs and assumed return on plan assets, are recorded in Other (income) expense. We recognize net actuarial gains or losses in excess of 10% of the greater of the fair value of plan assets or the plan's projected benefit obligation (the corridor) annually in the fourth quarter each year (MTM Adjustment). The MTM Adjustment is also reported in Other (income) expense. SALES RECOGNITION Product and service sales are recognized when or as the Company transfers control of the promised products or services to its customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Service sales, principally representing repair, maintenance and engineering activities, are recognized over the contractual period or as services are rendered. Sales under long-term contracts with performance obligations satisfied over time are recognized using either an input or output method. We recognize revenue over time as we perform on these contracts because of the continuous transfer of control to the customer. With control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. We generally use the cost-to-cost input method of progress for our contracts because it best depicts the transfer of control to the customer that occurs as we incur costs. Under the cost-to-cost method, the extent of progress towards completion is measured based on the proportion of costs incurred to date to the total estimated costs at completion of the performance obligation. We review our cost estimates on significant contracts on a periodic basis, or when circumstances change and warrant a modification to a previous estimate. Cost estimates are largely based on negotiated or estimated purchase contract terms, historical performance trends and other economic projections. Significant factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, asset utilization, and anticipated labor agreements. Provisions for anticipated losses on long-term contracts are recorded in full when such losses become evident, to the extent required. The customer funding for costs incurred for nonrecurring engineering and development activities of our products under agreements with commercial customers is deferred and subsequently recognized as revenue as products are delivered to the customers. Additionally, expenses incurred, up to the customer agreed funded amount, are deferred as an asset and recognized as cost of sales when products are delivered to the customer. The deferred customer funding and costs result in recognition of deferred costs (asset) and deferred revenue (liability) on our Consolidated Balance Sheet. Capitalized contract fulfillment costs were approximately $1.3 billion and $1 billion as of December 31, 2020 and 2019. The amounts recognized as Cost of products and services sold were approximately $0.1 billion for the years ended December 31, 2020, 2019 and 2018. Revenues for our mechanical service programs are recognized as performance obligations that are satisfied over time, with recognition reflecting a series of distinct services using the output method. The terms of a contract or the historical business practice can give rise to variable consideration due to, but not limited to, cash-based incentives, rebates, performance awards, or credits. We estimate variable consideration at the most likely amount we will receive from customers. We include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for such transaction will not occur, or when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. STOCK-BASED COMPENSATION PLANS The principal awards issued under our stock-based compensation plans, which are described in Note 16 Stock-Based Compensation Plans, are non-qualified stock options and restricted stock units. The cost for such awards is measured at the grant date based on the fair value of the award. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods (generally the vesting period of the equity award) and is included in Selling, general and administrative expenses. Forfeitures are estimated at the time of grant to recognize expense for those awards that are expected to vest and are based on our historical forfeiture rates. INCOME TAXES Significant judgment is required in evaluating tax positions. We establish reserves for income taxes when, despite the belief that tax positions are fully supportable, there remain certain positions that do not meet the minimum recognition threshold. The approach for evaluating certain and uncertain tax positions is defined by the authoritative guidance which determines when a tax position is more likely than not to be sustained upon examination by the applicable taxing authority. In the normal course of business, the Company and its subsidiaries are examined by various federal, state and foreign tax authorities. We regularly assess the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of our provision for income taxes. We continually assess the likelihood and amount of potential adjustments and adjust the income tax provision, the current tax liability and deferred taxes in the period in which the facts that give rise to a change in estimate become known. During 2020, the Company revised the disclosure of deferred tax assets and deferred tax liabilities in Note 5 Income Taxes as of December 31, 2019, to present separately the deferred tax liability for Right-of-use assets of $159 million and the deferred tax asset for Lease liabilities of $167 million, which were previously reported net within the deferred tax liability for Property, plant and equipment. This had no other impact to our Consolidated Financial Statements. For additional information, see Note 5 Income Taxes. EARNINGS PER SHARE Basic earnings per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding and all dilutive potential common shares outstanding. ENVIRONMENTAL The Company accrues costs related to environmental matters when it is probable that it has incurred a liability related to a contaminated site and the amount can be reasonably estimated. For additional information, see Note 20 Commitments and Contingencies. ASBESTOS RELATED LIABILITIES AND INSURANCE RECOVERIES The Company recognizes a liability for any asbestos related contingency that is probable of occurrence and reasonably estimable. In connection with the recognition of liabilities for asbestos related matters, we record asbestos related insurance recoveries that are deemed probable. For additional information, see Note 20 Commitments and Contingencies. REIMBURSEMENT RECEIVABLES In conjunction with the Garrett and Resideo spin-offs, the Company entered into reimbursement agreements under which Honeywell receives cash payments as reimbursement primarily for asbestos related liability payments related to the Bendix business in the U.S. (Garrett) and for net spending for environmental matters at certain sites as defined in the agreement (Resideo). Accordingly, the Company recorded receivables based on estimates of the underlying reimbursable Honeywell asbestos and environmental spend, and we monitor the recoverability of such receivables, which are subject to the terms of applicable credit agreements and general ability to pay. For Garrett, the Company established an allowance based on the developments associated with Garrett's Chapter 11 bankruptcy filing. See Note 20 Commitments and Contingencies for a discussion of the recognition and measurement of our reimbursement receivables, including the allowance established for Garrett.
