FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]

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:


	December 31, 2023								December 31, 2022
	Level 1		Level 2		Level 3			Total			Level 1			Level 2			Level 3	Total

The Company values foreign currency exchange contracts, interest rate swap agreements, cross currency swap agreements, and commodity contracts 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, time deposits, and corporate debt securities that are designated as available for sale. These investments are valued using published prices based on observable market data. As such, these investments are classified within level 2.

The Company holds certain available for sale investments in U.S. government securities and investments in equity securities. The Company values these investments 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 other short-term borrowings contained in the Consolidated Balance Sheet approximates fair value.

As part of the NARCO Buyout (see Note 19 Commitments and Contingencies for definition), Honeywell holds a right to proceeds from the definitive sale agreement pursuant to which HarbisonWalker International Holdings, Inc. (HWI), the reorganized and renamed entity that emerged from the NARCO Bankruptcy, was acquired by an affiliate of Platinum Equity, LLC (HWI Sale). The right to these proceeds is considered a financial instrument. The significant input for the valuation of this right is unobservable, and as such, is classified within level 3.

The HWI Sale closed on February 16, 2023. During the twelve months ended December 31, 2023, Honeywell received $275 million of proceeds from the HWI Sale (HWI Net Sale Proceeds), of which $256 million was received during the first quarter of 2023 and $19 million during the second quarter of 2023. Additionally, during the second quarter of 2023, the Company recorded a fair value adjustment for the HWI Net Sale Proceeds and reduced the estimate by $11 million. The fair value of the remaining HWI Net Sale Proceeds as of December 31, 2023, represents contingent consideration to be paid in future periods if certain conditions under the definitive sale agreement for the HWI Sale are met.

The following table sets forth a reconciliation of beginning and ending balances of assets and liabilities that were accounted for at fair value using level 3 measurements:


	Years Ended December 31,
	2023		2022
Balance at beginning of period	$	295	$	—

Recognition of right to HWI Net Sale Proceeds	—		295
Receipt of HWI Net Sale Proceeds	(275)		—
Fair value adjustment of HWI Net Sale Proceeds	(11)		—
Balance at end of period	$	9	$	295

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


	December 31, 2023				December 31, 2022
	Carrying Value		Fair Value		Carrying Value		Fair Value

Long-term receivables	$	232	$	173	$	229	$	183

Liabilities
Long-term debt and related current maturities	18,358		17,706		16,853		15,856

The Company determined the fair value of the long-term receivables by utilizing transactions in the listed markets for identical or similar assets. As such, the fair value of these receivables is considered level 2.

The Company determined the fair value of the long-term debt and related current maturities utilizing transactions in the listed markets for identical or similar liabilities. As such, the fair value of the long-term debt and related current maturities is considered level 2.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Dec. 31, 2023
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. The Company's consolidation policy requires equity investments that the Company exercises significant influence over, but does 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 the Company is not able to exercise significant influence over the investee and which the Company does 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 are reclassified to conform to the current year presentation. Historically, the Company included Company-sponsored costs and costs that relate to contracts with customers for research and development projects as a component of Cost of products and services sold on the Consolidated Statement of Operations. Effective January 1, 2023, the Company began classifying Company-sponsored costs for research and development projects as a separate financial statement line item, titled Research and development expenses, on the Consolidated Statement of Operations and recast prior period results for this reclassification. This reclassification had no impact on the Company's net income, earnings per share, cash flows, segment reporting, or financial position. The Company revised historical periods to reflect this change in 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 the Company's Consolidated Statement of Operations, Balance Sheet, and Cash Flows (Consolidated Financial Statements). In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Taxes Disclosures, which requires greater disaggregation of income tax disclosures. The new standard requires additional information to be disclosed with respect to the income tax rate reconciliation and income taxes paid disaggregated by jurisdiction. This ASU should be applied prospectively for fiscal years beginning after December 15, 2024, with retrospective application permitted. The Company is currently evaluating the impacts of this guidance on the Company’s Consolidated Financial Statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires companies to enhance the disclosures about segment expenses. The new standard requires the disclosure of the Company’s Chief Operating Decision Maker (CODM), expanded incremental line-item disclosures of significant segment expenses used by the CODM for decision-making, and the inclusion of previous annual only segment disclosure requirements on a quarterly basis. This ASU should be applied retrospectively for fiscal years beginning after December 15, 2023, and early adoption is permitted. The Company is currently evaluating the impacts of this guidance on the Company’s Consolidated Financial Statements. In September 2022, the FASB issued ASU 2022-04, Liabilities—Supplier Finance Programs (Topic 405): Disclosure of Supplier Finance Program Obligations, to enhance the transparency of supplier finance programs. The new standard requires annual disclosure of the key terms of the program, a description of where in the financial statements amounts outstanding under the program are presented, a rollforward of such amounts, and interim disclosure of amounts outstanding as of the end of each period. The guidance does not affect recognition, measurement, or financial statement presentation of supplier finance programs. The ASU is effective on January 1, 2023, except for the rollforward, which is effective on January 1, 2024. The Company adopted this guidance on January 1, 2023, with the exception of the rollforward that is effective on January 1, 2024. The adoption of this standard does not have a material impact on the Company’s Consolidated Financial Statements. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers. This ASU should be applied prospectively to acquisitions occurring on or after the effective date of December 15, 2022, and early adoption was permitted. The Company adopted this guidance on January 1, 2022. The adoption of this standard does not have a material impact on the Company’s Consolidated Financial Statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by the transition away from reference rates expected to be discontinued to alternative reference rates. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope, to expand the scope of this guidance to include derivatives. 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. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which extends the period of time entities can utilize the reference rate reform relief guidance under ASU 2020-04 from December 31, 2022, to December 31, 2024. The Company will apply the guidance to impacted transactions during the transition period. The adoption of this standard does not 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 the Company receives reimbursements. Amounts expensed as incurred for Company-sponsored research and development projects are included in Research and development expenses and were $1,456 million, $1,478 million, and $1,333 million for the years ended December 31, 2023, 2022, and 2021, respectively. 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 the Company's sales recognition policies.
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.
Inventories	INVENTORIES Inventories are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out basis. Carrying value adjustments for inventory obsolescence is equal to the difference between the cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.
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 3 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 Goodwill and indefinite-lived intangible assets are subject to impairment testing annually as of the first day of the fourth quarter, or if a triggering event occurs 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, not to exceed the carrying value of goodwill. The Company completed its annual goodwill impairment test as of the first day of the fourth quarter and determined there was no impairment as of that date. The Company is not aware of any additional triggering events. Prior to 2022, the Company performed its annual goodwill and intangible asset impairment test as of the last day of the first quarter. In 2022, the Company changed the date of its annual goodwill and intangible asset impairment assessment to the first day of the fourth quarter. The Company believes this change does not represent a material change in method of applying an accounting principle. This change has been applied prospectively as of the date of the change, as retrospective application is deemed impracticable due to the inability to objectively determine the assumptions used in earlier periods without the benefit of hindsight. This voluntary change is preferable under the circumstances as it results in better alignment with the timing of the Company’s forecasting process and reduces the time period between the assessment date and annual financial statements. This change in accounting principle does not delay, accelerate, or avoid an impairment of goodwill. In 2022, due to this change, the Company performed annual goodwill and intangible asset impairment tests as of the last day of the first quarter and the first day of the fourth quarter.
Definite-Lived Intangible Assets	DEFINITE-LIVED INTANGIBLE ASSETS Other intangible assets with definite lives consist of customer relationships, patents and technology, trademarks, and other intangibles and are amortized over their estimated useful lives, ranging from 2 to 20 years.
Capitalized Software	CAPITALIZED SOFTWARE The Company capitalizes costs of software developed or obtained for internal use during the application development stage of a project and amortizes those costs using the straight-line method over the expected useful life of the software, not to exceed 7 years. Costs incurred during the preliminary and post-implementation stages are expensed as incurred. Development costs for software held for sale are capitalized once a project has reached the point of technological feasibility. Completed projects are amortized after reaching the point of general availability using the straight-line method based on the expected useful life, not to exceed 7 years. At each balance sheet date, or earlier if an indicator of an impairment exists, the Company evaluates the recoverability of unamortized capitalized software costs based on estimated future undiscounted revenues net of estimated related costs over the remaining amortization period. Capitalized software held for internal use and held for sale is included in Other assets in the Consolidated Balance Sheet.
Foreign Currency Translation	FOREIGN CURRENCY TRANSLATION Assets and liabilities of subsidiaries operating outside the United States with a functional currency other than the U.S. Dollar 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. The Company elected to exclude the time value of the derivatives (i.e., the forward points) from the assessment of hedge effectiveness and to 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 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 (i) whether the contract involves the use of a distinct identified asset, (ii) whether the Company obtains the right to substantially all the economic benefit from the use of the asset throughout the period, and (iii) 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. A ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (short-term leases); however, lease expense for these leases is recognized as incurred over the lease term. ROU assets represent the Company's right to use an underlying asset during the reasonably certain lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company 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 costs and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. The Company primarily uses its 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, the Company considers the lease term, secured incremental borrowing rate, and for leases denominated in a currency different than the 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 pension 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 Cost of products and services sold, Research and development expenses, 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. The Company recognizes 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.
Supply Chain Financing	SUPPLY CHAIN FINANCING The Company maintains agreements with third-party financial institutions that offer voluntary supply chain financing (SCF) programs to suppliers. The SCF programs enable suppliers, at their sole discretion, to sell their receivables to third-party financial institutions in order to receive payment on receivables earlier than the negotiated commercial terms between suppliers and the Company. Supplier sale of receivables to third-party financial institutions is on terms negotiated between the supplier and the respective third-party financial institution. The Company agrees on commercial terms for the goods and services procured from suppliers, including prices, quantities, and payment terms, which normally range between 60 and 120 days, regardless of whether the supplier elects to participate in the SCF programs. A suppliers’ voluntary participation in the SCF programs has no bearing on the Company's payment terms and the Company has no economic interest in a supplier’s decision to participate in the SCF programs. The Company agrees to pay participating third-party financial institutions the stated amounts of confirmed invoices from suppliers on the original maturity dates of the invoices.
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 the Company expects 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. The Company recognizes revenue over time as the Company performs 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. The Company generally uses the cost-to-cost input method of progress for contracts because it best depicts the transfer of control to the customer that occurs as the Company incurs costs. Under the cost-to-cost input 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. The Company reviews its 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 risks, 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 the Company's 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) within Other assets and Accrued liabilities, respectively, in the Consolidated Balance Sheet. Deferred contract fulfillment costs were approximately $1.2 billion and $1.3 billion as of December 31, 2023, and 2022, respectively. The amounts recognized as Cost of products and services sold were approximately $0.1 billion for the year ended December 31, 2023, and $0.2 billion and $0.1 billion for 2022 and 2021, respectively. Revenues for the Company's 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. The Company estimates variable consideration at the most likely amount the Company will receive from customers. The Company includes 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. The Company's estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company's anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company.
Stock-Based Compensation Plans	STOCK-BASED COMPENSATION PLANS The principal awards issued under the Company's stock-based compensation plans, which are described in Note 15 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 expected to vest and are based on the Company's historical forfeiture rates.
Income Taxes	INCOME TAXES Significant judgment is required in evaluating tax positions. The Company establishes reserves for income taxes when, despite the belief that tax positions are fully supportable, certain positions remain 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. The Company regularly assesses the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of the Company's provision for income taxes. The Company continually assesses the likelihood and amount of potential adjustments and adjusts 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. See Note 5 Income Taxes for additional information.
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. See Note 19 Commitments and Contingencies for additional information.
Reimbursement Receivables	REIMBURSEMENT RECEIVABLES In conjunction with the Resideo Technologies, Inc. (Resideo) spin-off, the Company entered into a reimbursement agreement under which Honeywell receives cash payments as reimbursement primarily related to net spending for environmental matters at certain sites as defined in the reimbursement agreement. Accordingly, the Company recorded receivables based on estimates of the underlying reimbursable Honeywell environmental spend, and the Company monitors the recoverability of such receivables, which are subject to the terms of applicable credit agreements and general ability to pay.
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, the Company records asbestos-related insurance recoveries that are deemed probable. See Note 19 Commitments and Contingencies for additional information.

The Company tracks progress on satisfying performance obligations under contracts with customers. The related billings and cash collections are recorded in 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 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. Contract 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 the Company 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.

DERIVATIVE INSTRUMENTS AND HEDGING TRANSACTIONS

12 Months Ended

Dec. 31, 2023

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE INSTRUMENTS AND HEDGING TRANSACTIONS

DERIVATIVES AND HEDGING ACTIVITIES

The Company uses derivative financial instruments to manage its risks related to interest rates, foreign currency exchange rates, and commodity prices. 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. The Company's 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 as of the balance sheet date. The Company recognizes effects of changes in spot rates in Other (income) expense.

The Company uses foreign currency exchange contracts to hedge foreign currency exposure. These contracts are marked-to-market in net income and offset gains and losses on the non-functional currency denominated monetary assets and liabilities being hedged. The Company also 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, 2023, and 2022, the Company held contracts with notional amounts of $8,910 million and $10,545 million, respectively, to exchange foreign currencies, principally the U.S. Dollar, Euro, Canadian Dollar, British Pound, Mexican Peso, Chinese Renminbi, and Indian Rupee.

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 the Company's 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 the Company's credit sales are designed to mitigate or eliminate concentrations of credit risk with any single customer. The Company's sales are not materially dependent on a single customer or a small group of customers.

COMMODITY PRICE RISK MANAGEMENT

The Company's operations subject the Company to risk related to the price volatility of certain commodities. To mitigate the commodity price risk associated with the Company's operations, the Company may enter into commodity derivative instruments. In both 2023 and 2022, the Company entered into various contracts to mitigate commodity price volatility. The Company elected to apply hedge accounting to these contracts.

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:

All Derivative assets are presented in Other current assets or Other assets. All Derivative liabilities are presented in Accrued liabilities or Other liabilities.

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 $6,099 million and $3,836 million as of December 31, 2023, and 2022, respectively.

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 $121 million of income, $347 million of expense, and $135 million of expense for the years ended December 31, 2023, 2022, and 2021, respectively. Gains and losses are fully offset by losses and gains on the underlying debt being hedged.

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


	Carrying Amount of Hedged Item				Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of Hedged Item

STOCK-BASED COMPENSATION PLANS

Share-Based Payment Arrangement [Abstract]

STOCK-BASED COMPENSATION PLANS

The 2016 Stock Incentive Plan of Honeywell International Inc. and its Affiliates (2016 Plan) and 2016 Stock Plan for Non-Employee Directors of Honeywell International Inc. (2016 Directors Plan) were both approved by the shareowners at the Annual Meeting of Shareowners effective on April 25, 2016. At December 31, 2023, there were 28,946,133 and 781,768 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 the Company's 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 the Company's common stock. The Company 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.

The following table summarizes the impact to the Consolidated Statement of Operations from stock options:


	Years Ended December 31,
	2023		2022		2021
Compensation expense	$	48	$	45	$	55

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. Certain RSU awards are performance-based and awarded to eligible employees which entitle the grantee to receive shares of common stock if specified Company performance goals are achieved during the performance period and if the grantee remains employed through the vesting period.

The following table summarizes information about RSU activity for the three years ended December 31, 2023:

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS AND DIVESTITURES	ACQUISITIONS On December 8, 2023, the Company agreed to acquire Carrier Global Corporation's Global Access Solutions business in an all-cash transaction for $5.0 billion. The transaction is subject to regulatory review and approval and customary closing conditions. The transaction is expected to close by the end of the third quarter of 2024 and the business will be reported within the Building Automation reportable business segment. On August 25, 2023, the Company acquired 100% of the outstanding equity interests of SCADAfence, a provider of operational technology and Internet of Things cybersecurity solutions for monitoring large scale networks, for total consideration of $52 million, net of cash acquired. The business is included in the Industrial Automation reportable business segment. The assets and liabilities acquired with SCADAfence are included in the Consolidated Balance Sheet as of December 31, 2023, including $17 million of intangible assets and $42 million of goodwill, which is not deductible for tax purposes. The purchase accounting is subject to final adjustment, primarily for the value of intangible assets, amounts allocated to goodwill, and tax balances. On June 30, 2023, the Company acquired 100% of the outstanding equity interests of Compressor Controls Corporation, a turbomachinery services and controls company based in the United States, for total cash consideration of $673 million, net of cash acquired. The business is included in the Industrial Automation reportable business segment. The assets and liabilities acquired with Compressor Controls Corporation are included in the Consolidated Balance Sheet as of December 31, 2023, including $282 million of intangible assets and $350 million allocated to goodwill, which is deductible for tax purposes. The identifiable intangible assets primarily include customer relationships amortized over an estimated life of 15 years using an excess earnings amortization method. The purchase accounting is subject to final adjustment, primarily for the valuation of intangible assets, amounts allocated to goodwill, and tax balances. On January 18, 2022, the Company acquired 100% of the issued and outstanding shares of US Digital Designs, Inc., a leading provider of technologies for first responders, for total consideration of $186 million. The business is included within the Building Automation reportable business segment. The Company finalized the evaluation for the fair value of all the assets and liabilities acquired with US Digital Designs, Inc. during the first quarter of 2023. Management recorded intangible assets of $53 million and allocated $129 million to goodwill, which is deductible for tax purposes. On November 29, 2021, Honeywell Quantum Solutions, a wholly-owned subsidiary of Honeywell, and Cambridge Quantum Computing, a leading developer of quantum computing and quantum software, combined to form Quantinuum. Prior to closing the transaction, Honeywell held a 4.2% ownership interest in Cambridge Quantum Computing. As part of the business combination, Honeywell contributed an additional $270 million of cash and is the controlling majority-owner of Quantinuum, with an overall 54% ownership in the business. Assets and liabilities of Quantinuum are consolidated by Honeywell and included in the Consolidated Balance Sheet. The business is included within Corporate and All Other, which is not a reportable business segment. Upon close of the transaction, Honeywell recorded a non-cash adjustment of $460 million in Additional paid-in capital in the Consolidated Balance Sheet as the contribution of ownership interest in Honeywell Quantum Solutions and Cambridge Quantum Computing for the formation of Quantinuum. In addition, Honeywell recognized a gain of $22 million related to the fair value remeasurement of Honeywell's existing 4.2% ownership interest in Cambridge Quantum Computing, which was recorded in Other (income) expense in the Consolidated Statement of Operations. At close of the transaction, the fair value of Cambridge Quantum Computing's noncontrolling interest in Quantinuum was $419 million.

1						Net of changes in valuation allowance.
2						Includes U.S. taxes on non-U.S. earnings, net of foreign tax credits.
3						2023 includes (3.6)% deferred tax benefit resulting from a non-U.S. legislative change, offset by 3.6% deferred tax expense resulting from a full valuation allowance.

The effective tax rate decreased by 1.3 percentage points in 2023 compared to 2022. The decrease was primarily attributable to the increased benefit of taxes on non-U.S. earnings and lower expense related to unremitted withholding taxes on non-U.S. earnings, partially offset by incremental tax expense for reserves. The Company’s 2023 non-U.S. effective tax rate was 25.3%, a decrease of approximately 2.2 percentage points compared to 2022. The decrease in the non-U.S. effective tax rate was primarily attributable to increased benefit of taxes on non-U.S. earnings and lower expense related to unremitted withholding taxes on non-U.S. earnings, partially offset by incremental tax expense for reserves.

The effective tax rate decreased by 0.4 percentage points in 2022 compared to 2021. The decrease was primarily a result of additional tax expense reported in 2021 arising from a valuation allowance established against a capital loss, partially offset by a tax benefit related to restructuring transactions. In 2022, the valuation allowance was partially released as losses were utilized against a capital gain. Additionally, in 2022, there was lower tax expense reported for contingencies as a result of the release of certain state income tax reserves. The Company’s 2022 non-U.S. effective tax rate was 27.5%, an increase of approximately 1.5 percentage points compared to 2021. The increase in the non-U.S. effective tax rate was primarily attributable to a 2021 tax benefit recorded for the release of a valuation allowance on net operating losses due to restructuring in Canada, which resulted in more tax expense in 2022 compared to 2021. This increase was partially offset by lower tax expense recorded in 2022 related to tax reserves when compared to 2021.

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,

Other	(5)		(1)
Total deferred tax liabilities	(3,546)		(3,186)
Net deferred tax liability	$	(1,702)	$	(1,672)

The Company's gross deferred tax assets include $1,378 million related to non-U.S. operations comprised primarily of net operating losses and other tax attribute carryforwards in Canada, France, Germany, Luxembourg, Switzerland, and the United Kingdom. The Company maintains a valuation allowance of $1,176 million against a portion of the non-U.S. gross deferred tax assets and a valuation allowance of $116 million against the U.S. gross deferred tax asset, primarily related to capital loss carryovers. The change in the valuation allowance resulted in an increase of $458 million, a decrease of $8 million, and an increase of $124 million to income tax expense in 2023, 2022, and 2021, respectively. The majority of the $458 million increase in 2023 tax expense relates to a $257 million valuation allowance resulting from uncertainty regarding the realizability of a $257 million deferred tax asset established as a result of a non-U.S. tax legislative change. The remaining $201 million relates to other tax attribute carryforwards. If the Company determines that the likelihood of realization of existing deferred tax assets changes, a corresponding increase or decrease to valuation allowances will be recognized as an increase or reduction to income tax expense in the period that determination is made.

As of December 31, 2023, the Company recorded a $542 million deferred tax liability on all unremitted foreign earnings based on estimated earnings and profits of approximately $15 billion as of the balance sheet date.

As of December 31, 2023, the Company's net operating loss, capital loss, tax credit carryforwards, and other attributes were as follows:


Jurisdiction	Net Operating and Capital Loss Carryforwards		Tax Credit Carryforwards and Other Attributes
U.S. Federal	$	532	$	96
U.S. State	675		25
Non-U.S.	3,720		304
Total	$	4,927	$	425

Many jurisdictions impose limitations on the timing and utilization of net operating loss and tax credit carryforwards. Approximately $3,140 million of the non-U.S. net operating loss has no expiration period. The U.S. federal capital loss carryforward of $502 million expires in 2026. The remaining net operating loss, capital loss and credit carryforwards, and other tax attributes have expiration periods through 2043.

As of December 31, 2023, 2022, and 2021, there were $1,225 million, $1,086 million, and $1,061 million, respectively, 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, 2023:


Jurisdiction	Open Tax Years
	Examination in progress	Examination not yet initiated
U.S. Federal	2017-2021	2022-2023
U.S. State	2013-2021	2022-2023
China	2013-2022	2023
Germany	2013-2020	2021-2023
India	2013-2020	2021-2023
Puerto Rico	N/A	2020-2023
Switzerland	2019-2020	2021-2023
United Kingdom	2013-2021	2022-2023

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 the Company's 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 $803 million, $640 million, and $592 million as of December 31, 2023, 2022, and 2021, respectively. 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 $74 million, $5 million, and $79 million for the years ended December 31, 2023, 2022, and 2021, respectively. Accrued interest and penalties were $612 million, $557 million, and $580 million as of December 31, 2023, 2022, and 2021, respectively.

- Definition

SEGMENT FINANCIAL DATA

Segment Reporting [Abstract]

SEGMENT FINANCIAL DATA

Honeywell globally manages its business operations through four reportable business 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.

Effective during the first quarter of 2024, the Company realigned certain of its business units comprising its historical Performance Materials and Technologies, and Safety and Productivity Solutions reportable business segments by forming two new reportable business segments: Industrial Automation, and Energy and Sustainability Solutions. Industrial Automation includes Sensing and Safety Technologies, Productivity Solutions and Services, and Warehouse and Workflow Solutions, previously included in Safety and Productivity Solutions, in addition to Process Solutions, previously included in Performance Materials and Technologies. Energy and Sustainability Solutions includes UOP and Advanced Materials, previously included in Performance Materials and Technologies. Further, as part of the realignment, the Company renamed its historical Aerospace and Honeywell Building Technologies reportable business segments to Aerospace Technologies and Building Automation, respectively. This realignment had no impact on the Company’s historical consolidated financial position, results of operations, or cash flows. Prior period amounts have been recast.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Dec. 31, 2023
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. The Company's consolidation policy requires equity investments that the Company exercises significant influence over, but does 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 the Company is not able to exercise significant influence over the investee and which the Company does 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 are reclassified to conform to the current year presentation. Historically, the Company included Company-sponsored costs and costs that relate to contracts with customers for research and development projects as a component of Cost of products and services sold on the Consolidated Statement of Operations. Effective January 1, 2023, the Company began classifying Company-sponsored costs for research and development projects as a separate financial statement line item, titled Research and development expenses, on the Consolidated Statement of Operations and recast prior period results for this reclassification. This reclassification had no impact on the Company's net income, earnings per share, cash flows, segment reporting, or financial position. The Company revised historical periods to reflect this change in 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 the Company's Consolidated Statement of Operations, Balance Sheet, and Cash Flows (Consolidated Financial Statements). In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Taxes Disclosures, which requires greater disaggregation of income tax disclosures. The new standard requires additional information to be disclosed with respect to the income tax rate reconciliation and income taxes paid disaggregated by jurisdiction. This ASU should be applied prospectively for fiscal years beginning after December 15, 2024, with retrospective application permitted. The Company is currently evaluating the impacts of this guidance on the Company’s Consolidated Financial Statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires companies to enhance the disclosures about segment expenses. The new standard requires the disclosure of the Company’s Chief Operating Decision Maker (CODM), expanded incremental line-item disclosures of significant segment expenses used by the CODM for decision-making, and the inclusion of previous annual only segment disclosure requirements on a quarterly basis. This ASU should be applied retrospectively for fiscal years beginning after December 15, 2023, and early adoption is permitted. The Company is currently evaluating the impacts of this guidance on the Company’s Consolidated Financial Statements. In September 2022, the FASB issued ASU 2022-04, Liabilities—Supplier Finance Programs (Topic 405): Disclosure of Supplier Finance Program Obligations, to enhance the transparency of supplier finance programs. The new standard requires annual disclosure of the key terms of the program, a description of where in the financial statements amounts outstanding under the program are presented, a rollforward of such amounts, and interim disclosure of amounts outstanding as of the end of each period. The guidance does not affect recognition, measurement, or financial statement presentation of supplier finance programs. The ASU is effective on January 1, 2023, except for the rollforward, which is effective on January 1, 2024. The Company adopted this guidance on January 1, 2023, with the exception of the rollforward that is effective on January 1, 2024. The adoption of this standard does not have a material impact on the Company’s Consolidated Financial Statements. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, Revenue from Contracts with Customers. This ASU should be applied prospectively to acquisitions occurring on or after the effective date of December 15, 2022, and early adoption was permitted. The Company adopted this guidance on January 1, 2022. The adoption of this standard does not have a material impact on the Company’s Consolidated Financial Statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by the transition away from reference rates expected to be discontinued to alternative reference rates. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope, to expand the scope of this guidance to include derivatives. 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. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which extends the period of time entities can utilize the reference rate reform relief guidance under ASU 2020-04 from December 31, 2022, to December 31, 2024. The Company will apply the guidance to impacted transactions during the transition period. The adoption of this standard does not 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 the Company receives reimbursements. Amounts expensed as incurred for Company-sponsored research and development projects are included in Research and development expenses and were $1,456 million, $1,478 million, and $1,333 million for the years ended December 31, 2023, 2022, and 2021, respectively. 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 the Company's sales recognition policies. This revenue was $1,303 million, $1,336 million, and $1,284 million for the years ended December 31, 2023, 2022, and 2021, respectively. 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. INVENTORIES Inventories are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out basis. Carrying value adjustments for inventory obsolescence is equal to the difference between the cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. 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 3 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 the first day of the fourth quarter, or if a triggering event occurs 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, not to exceed the carrying value of goodwill. The Company completed its annual goodwill impairment test as of the first day of the fourth quarter and determined there was no impairment as of that date. The Company is not aware of any additional triggering events. Prior to 2022, the Company performed its annual goodwill and intangible asset impairment test as of the last day of the first quarter. In 2022, the Company changed the date of its annual goodwill and intangible asset impairment assessment to the first day of the fourth quarter. The Company believes this change does not represent a material change in method of applying an accounting principle. This change has been applied prospectively as of the date of the change, as retrospective application is deemed impracticable due to the inability to objectively determine the assumptions used in earlier periods without the benefit of hindsight. This voluntary change is preferable under the circumstances as it results in better alignment with the timing of the Company’s forecasting process and reduces the time period between the assessment date and annual financial statements. This change in accounting principle does not delay, accelerate, or avoid an impairment of goodwill. In 2022, due to this change, the Company performed annual goodwill and intangible asset impairment tests as of the last day of the first quarter and the first day of the fourth quarter. DEFINITE-LIVED INTANGIBLE ASSETS Other intangible assets with definite lives consist of customer relationships, patents and technology, trademarks, and other intangibles and are amortized over their estimated useful lives, ranging from 2 to 20 years. CAPITALIZED SOFTWARE The Company capitalizes costs of software developed or obtained for internal use during the application development stage of a project and amortizes those costs using the straight-line method over the expected useful life of the software, not to exceed 7 years. Costs incurred during the preliminary and post-implementation stages are expensed as incurred. Development costs for software held for sale are capitalized once a project has reached the point of technological feasibility. Completed projects are amortized after reaching the point of general availability using the straight-line method based on the expected useful life, not to exceed 7 years. At each balance sheet date, or earlier if an indicator of an impairment exists, the Company evaluates the recoverability of unamortized capitalized software costs based on estimated future undiscounted revenues net of estimated related costs over the remaining amortization period. Capitalized software held for internal use and held for sale is included in Other assets in the Consolidated Balance Sheet. FOREIGN CURRENCY TRANSLATION Assets and liabilities of subsidiaries operating outside the United States with a functional currency other than the U.S. Dollar 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. The Company elected to exclude the time value of the derivatives (i.e., the forward points) from the assessment of hedge effectiveness and to 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 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 (i) whether the contract involves the use of a distinct identified asset, (ii) whether the Company obtains the right to substantially all the economic benefit from the use of the asset throughout the period, and (iii) 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. A ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (short-term leases); however, lease expense for these leases is recognized as incurred over the lease term. ROU assets represent the Company's right to use an underlying asset during the reasonably certain lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company 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 costs and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. The Company primarily uses its 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, the Company considers the lease term, secured incremental borrowing rate, and for leases denominated in a currency different than the 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 pension 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 Cost of products and services sold, Research and development expenses, 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. The Company recognizes 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. SUPPLY CHAIN FINANCING The Company maintains agreements with third-party financial institutions that offer voluntary supply chain financing (SCF) programs to suppliers. The SCF programs enable suppliers, at their sole discretion, to sell their receivables to third-party financial institutions in order to receive payment on receivables earlier than the negotiated commercial terms between suppliers and the Company. Supplier sale of receivables to third-party financial institutions is on terms negotiated between the supplier and the respective third-party financial institution. The Company agrees on commercial terms for the goods and services procured from suppliers, including prices, quantities, and payment terms, which normally range between 60 and 120 days, regardless of whether the supplier elects to participate in the SCF programs. A suppliers’ voluntary participation in the SCF programs has no bearing on the Company's payment terms and the Company has no economic interest in a supplier’s decision to participate in the SCF programs. The Company agrees to pay participating third-party financial institutions the stated amounts of confirmed invoices from suppliers on the original maturity dates of the invoices. Amounts outstanding related to SCF programs are included in Accounts payable in the Consolidated Balance Sheet. Accounts payable included approximately $1,112 million and $992 million as of December 31, 2023, and 2022, respectively. The impact of these programs is not material to the Company's overall liquidity. 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 the Company expects 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. The Company recognizes revenue over time as the Company performs 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. The Company generally uses the cost-to-cost input method of progress for contracts because it best depicts the transfer of control to the customer that occurs as the Company incurs costs. Under the cost-to-cost input 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. The Company reviews its 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 risks, 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 the Company's 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) within Other assets and Accrued liabilities, respectively, in the Consolidated Balance Sheet. Deferred contract fulfillment costs were approximately $1.2 billion and $1.3 billion as of December 31, 2023, and 2022, respectively. The amounts recognized as Cost of products and services sold were approximately $0.1 billion for the year ended December 31, 2023, and $0.2 billion and $0.1 billion for 2022 and 2021, respectively. Revenues for the Company's 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. The Company estimates variable consideration at the most likely amount the Company will receive from customers. The Company includes 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. The Company's estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company's anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company. STOCK-BASED COMPENSATION PLANS The principal awards issued under the Company's stock-based compensation plans, which are described in Note 15 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 expected to vest and are based on the Company's historical forfeiture rates. INCOME TAXES Significant judgment is required in evaluating tax positions. The Company establishes reserves for income taxes when, despite the belief that tax positions are fully supportable, certain positions remain 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. The Company regularly assesses the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of the Company's provision for income taxes. The Company continually assesses the likelihood and amount of potential adjustments and adjusts 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. See Note 5 Income Taxes for additional information. 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. See Note 19 Commitments and Contingencies for additional information. REIMBURSEMENT RECEIVABLES In conjunction with the Resideo Technologies, Inc. (Resideo) spin-off, the Company entered into a reimbursement agreement under which Honeywell receives cash payments as reimbursement primarily related to net spending for environmental matters at certain sites as defined in the reimbursement agreement. Accordingly, the Company recorded receivables based on estimates of the underlying reimbursable Honeywell environmental spend, and the Company monitors the recoverability of such receivables, which are subject to the terms of applicable credit agreements and general ability to pay. 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, the Company records asbestos-related insurance recoveries that are deemed probable. See Note 19 Commitments and Contingencies for additional information.

NET REPOSITIONING CHARGES

In 2023, the Company recognized gross repositioning charges totaling $342 million, including severance costs of $162 million related to workforce reductions of 5,854 manufacturing and administrative positions mainly in the Company's Industrial Automation and Building Automation reportable business segments. The workforce reductions related to productivity and ongoing functional transformation initiatives. The repositioning charges included asset impairments of $41 million related to the write-down of certain assets within the Company's Industrial Automation reportable business segment and corporate function. The repositioning charges included exit costs of $139 million related to current period costs incurred for closure obligations associated with site transitions in the Company's Industrial Automation reportable business segment. Also, $56 million of previously established reserves, primarily for severance, were returned to income due to higher-than-expected voluntary exits and adjustments to the scope of previously announced repositioning actions.

In 2022, the Company recognized repositioning charges totaling $420 million, including severance costs of $122 million related to workforce reductions of 4,345 manufacturing and administrative positions mainly in the Company's Industrial Automation reportable business segment. The workforce reductions related to our productivity and ongoing functional transformation initiatives. The repositioning charges included asset impairments of $176 million related to the write-down of certain manufacturing and other equipment, primarily related to closing and relocating the production of certain respiratory manufacturing from a U.S.-based facility to a non-U.S. facility in the Company's Industrial Automation reportable business segment. The repositioning charges included exit costs of $122 million related to current period costs incurred for closure obligations associated with site transitions in the Company's Energy and Sustainability Solutions, Aerospace Technologies, and Industrial Automation reportable business segments. Also, $56 million of previously established reserves, primarily for severance, were returned to income due to higher than expected voluntary exits and adjustments to the scope of previously announced repositioning actions.

In 2021, the Company recognized repositioning charges totaling $331 million, including severance costs of $80 million related to workforce reductions of 6,432 manufacturing and administrative positions mainly in the Company's Industrial Automation and Aerospace Technologies reportable business segments. The workforce reductions were primarily related to the realignment of a product line in the Company's Industrial Automation reportable business segment, site transitions, mainly in the Aerospace Technologies reportable business segment, to more cost-effective locations, and the Company's productivity and ongoing functional transformation initiatives. The repositioning charges included asset impairments of $117 million primarily related to the write-down of certain manufacturing and other equipment. The repositioning charges included exit costs of $134 million primarily for current period exit costs incurred for previously approved repositioning projects, closure obligations associated with site transitions, and lease obligations for equipment. Also, $13 million of previously established reserves, primarily for severance, were returned to income due to adjustments to the scope of previously announced repositioning actions.

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 2023, 2022, and 2021 were $62 million, $63 million, and $45 million, respectively.

OTHER CHARGES

In 2022, the Company recognized $295 million of Other charges related to the initial suspension and the wind down of our business and operations in Russia. These costs impacted all reportable business segments, with the most significant impact within the Industrial Automation and Energy and Sustainability Solutions reportable business segments. The Other charges include costs recorded in Cost of products sold, Selling, general and administrative expenses, or Other (income) expense in the Consolidated Statement of Operations. Cost of products and services sold includes $65 million primarily related to inventory reserves and the write-down of other assets, Selling, general and administrative includes $185 million primarily related to reserves against outstanding accounts receivable and contract assets, impairment of intangible assets, the write-down of other assets, and employee severance, and Other (income) expense includes $45 million related to foreign exchange revaluation on an intercompany loan with a Russian affiliate, impairment of property, plant and equipment, and expenses for called guarantees. Directly attributable to our wind down of businesses and operations in Russia, but excluded from Other charges, is a $2 million tax valuation allowance recorded to Tax expense in the Consolidated Statement of Operations.

Given the uncertainty inherent in the Company's remaining obligations related to contracts with Russian counterparties, the Company does 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). Based on available information to date, the Company’s estimate of potential future losses or other contingencies related to suspension and wind down activities, including any guarantee payments or any litigation costs or as otherwise related to the Company's wind down in Russia, could adversely affect the Company's consolidated results of operations in the periods recognized but would not be material with respect to the Company's consolidated financial position. See Note 19 Commitments and Contingencies for a discussion of the recognition and measurement of estimate for contingencies.

Additionally, for the years ended December 31, 2022, and 2021, Other charges include $41 million and $105 million, respectively, of incremental long-term contract labor cost inefficiencies due to severe supply chain disruptions (attributable to the COVID-19 pandemic) relating to the warehouse automation business within the Industrial Automation reportable business segment. Certain of these costs incurred include amounts and provisions for anticipated losses recognized during 2022 and 2021 when total estimated costs at completion for certain of the business’ long-term contracts exceeded total estimated revenue. These costs represent unproductive labor costs due to unexpected supply delays and the resulting downstream installation issues, demobilization and remobilization of contract workers, and resolution of contractor disputes. These costs do not include normal operational inefficiencies experienced during a challenging operating environment in 2022 and 2021.

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. The Company believes that, as a general matter, the Company's policies, practices, and procedures are properly designed to prevent unreasonable risk of environmental damage and personal injury and that the 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, the Company, like other companies engaged in similar businesses, incurred remedial response and voluntary cleanup costs for site contamination and is 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 the Company's 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, the Company does not believe it is possible to develop an estimate of the range of reasonably possible environmental loss in excess of the Company's recorded liabilities. The Company expects to fund expenditures for these matters from operating cash flows. 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:

Other liabilities	414		393
Total environmental liabilities	$	641	$	615

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 the Company's consolidated results of operations and operating cash flows in the periods recognized or paid. However, considering the Company's past experience and existing reserves, the Company does not expect that environmental matters will have a material adverse effect on its consolidated financial position.

In conjunction with the Resideo 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 2023 and 2022 and offset operating cash outflows incurred by the Company. As the Company incurs costs for environmental matters deemed probable and reasonably estimable related to the sites covered by the indemnification and reimbursement agreement, a corresponding receivable from Resideo for 90% of such costs is also recorded. This receivable amount recorded in 2023 and 2022 was $187 million and $157 million, respectively. As of December 31, 2023, Other current assets and Other assets included $140 million and $521 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, 2022, Other current assets and Other assets included $140 million and $474 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 NARCO, which was sold in 1986, and the Bendix Friction Materials (Bendix) business, which was sold in 2014.

1						As of December 31, 2022, Accrued liabilities included the Buyout Amount, as described and defined below, agreed upon between Honeywell and the Trust. The Buyout Amount does not represent an asbestos-related liability.

NARCO Products – NARCO manufactured high-grade, heat-resistant, refractory products for various industries. Honeywell’s predecessor, Allied Corporation, owned NARCO from 1979 to 1986. Allied Corporation sold the NARCO business in 1986 and entered into a cross-indemnity agreement which included an obligation to indemnify the purchaser for asbestos claims, arising primarily from alleged occupational exposure to asbestos-containing refractory brick and mortar for high-temperature applications. NARCO ceased manufacturing these products in 1980 and filed for bankruptcy in January 2002, at which point in time all then current and future NARCO asbestos claims were stayed against both NARCO and Honeywell pending the reorganization of NARCO. The Company established its initial liability for NARCO asbestos claims in 2002.

NARCO emerged from bankruptcy in April 2013, at which time a federally authorized 524(g) trust was established to evaluate and resolve all existing NARCO asbestos claims (the Trust). Both Honeywell and NARCO are protected by a permanent channeling injunction barring all present and future individual actions in state or federal courts and requiring all asbestos-related claims based on exposure to NARCO asbestos-containing products to be made against the Trust (Channeling Injunction). The NARCO Trust Agreement (TA) and the NARCO Trust Distribution Procedures (TDP) set forth the structure and operating rules of the Trust, and established Honeywell’s evergreen funding obligations.

The operating rules per the TDP define criteria claimants must meet for a claim to be considered valid and paid. Once operational in 2014, the Trust began to receive, process, and pay claims. In September 2021, Honeywell filed suit against the Trust in the United States Bankruptcy Court for the Western District of Pennsylvania (Bankruptcy Court) alleging that the Trust breached its duties in managing the Trust, including breaches of certain provisions of the TA and TDP. Honeywell's lawsuit sought appropriate relief preventing the Trust from continuing these practices. The Trust also filed suit against Honeywell, alleging Honeywell breached its obligations under the Trust's governing documents. Honeywell moved to dismiss the Trust’s suit, and on December 15, 2021, the Bankruptcy Court granted Honeywell’s motion to dismiss subject to granting the Trust leave to file an amended complaint. On December 28, 2021, the Trust filed an answer with counterclaims in response to Honeywell’s complaint and in lieu of filing an amended complaint. The Bankruptcy Court conducted a trial on these matters during May 2022; following the trial, the Company and the Trust began discussing a potential settlement of Honeywell’s remaining obligations to the Trust.

On November 18, 2022, Honeywell entered into a definitive agreement (Buyout Agreement) with the Trust, and on November 20, 2022, in exchange for the NARCO Trust Advisory Committee (TAC) and Lawrence Fitzpatrick, in his capacity as the NARCO Asbestos Future Claimants Representative (FCR), becoming parties to the Buyout Agreement, Honeywell, the Trust, the TAC, and the FCR entered into an Amended and Restated Buyout Agreement (Amended Buyout Agreement).

Pursuant to the terms of the Amended Buyout Agreement, Honeywell agreed to make a one-time, lump sum payment in the amount of $1.325 billion to the Trust (Buyout Amount), subject to certain deductions as described in the Amended Buyout Agreement and in exchange for the release by the Trust of Honeywell from all further and future obligations of any kind related to the Trust and/or any claimants who were exposed to asbestos-containing products manufactured, sold, or distributed by NARCO or its predecessors, including Honeywell’s ongoing evergreen obligation to fund (i) claims against the Trust, which comprise Honeywell’s NARCO asbestos-related claims liability, and (ii) the Trust’s annual operating expenses, which are expensed as incurred, including its legal fees (which operating expenses, for reference, were approximately $30 million in 2022) (such evergreen obligations referred to in (i) and (ii), Honeywell Obligations) (the NARCO Buyout).

On December 8, 2022, the Bankruptcy Court issued an order that (A) approved the Amended Buyout Agreement, and (B) declared that the NARCO Channeling Injunction (which bars all past, present, and future individual actions in state or federal courts based on exposure to NARCO asbestos-containing products and requires all such claims to be made against the Trust) will remain in full force and effect without modification, dissolution, or termination (Order).

On December 14, 2022, HWI, the reorganized and renamed entity that emerged from the NARCO bankruptcy, entered into a definitive agreement (Sale Agreement) pursuant to which an affiliate of Platinum Equity, LLC agreed to acquire HWI (HWI Sale) subject to the terms set forth in the Sale Agreement, including customary conditions to closing set forth therein. In accordance with the Amended Buyout Agreement, the economic rights of the Trust in respect of the net proceeds from the HWI Sale inure to the benefit of Honeywell.

On January 30, 2023, the Company paid the Buyout Amount to the Trust, the parties closed the transactions contemplated in the Amended Buyout Agreement (Closing), and Honeywell was released from the Honeywell Obligations. Honeywell continues to have the right to collect proceeds in connection with its NARCO asbestos-related insurance policies.

With the issuance of the Order, the Company derecognized the NARCO asbestos-related liability of $688 million from the Consolidated Balance Sheet and recognized a charge of $1.325 billion in the Consolidated Statement of Operations and accrued a corresponding liability in the Consolidated Balance Sheet for the Buyout Amount. In addition, the Company recognized a benefit of $295 million in the Consolidated Statement of Operations and corresponding asset in Other current assets in the Consolidated Balance Sheet for Honeywell's rights to the proceeds from the HWI Sale. The benefit of $295 million offset the charge for the Buyout Amount.

On February 16, 2023, the HWI Sale closed. Pursuant to the Amended Buyout Agreement, during 2023, Honeywell received $275 million of proceeds from the HWI sale. See Note 12 Fair Value Measurements for further information on the related proceeds and remaining amount under the Amended Buyout Agreement.

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:

	(in whole dollars)

The Consolidated Financial Statements reflect an estimated liability for resolution of asserted (claims filed as of the financial statement date) and unasserted Bendix-related asbestos claims, which exclude the Company’s ongoing legal fees to defend such asbestos claims which will continue to be expensed as they are incurred.

The Company reflects the inclusion of all years of epidemiological disease projection through 2059 when estimating the liability for unasserted Bendix-related asbestos claims. Such liability for unasserted Bendix-related asbestos claims is based on historic and anticipated claims filing experience and dismissal rates, disease classifications, and average resolution values in the tort system over a defined look-back period. The Company historically valued Bendix asserted and unasserted claims using a five-year look-back period. The Company reviews the valuation assumptions and average resolution values used to estimate the cost of Bendix asserted and unasserted claims during the fourth quarter each year.

The Company experienced fluctuations in average resolution values year-over-year in each of the past five years with no well-established trends in either direction. In 2023, the Company observed two consecutive years of increasing average resolution values (2023 and 2022), with more volatility in the earlier years of the five-year period (2019 through 2021). Based on these observations, the Company, during its annual review in the fourth quarter of 2023, reevaluated its valuation methodology and elected to give more weight to the two most recent years by shortening the look-back period from five years to two years (2023 and 2022). The Company believes that the average resolution values in the last two consecutive years are likely more representative of expected resolution values in future periods.

It is not possible to predict whether such resolution values will increase, decrease, or stabilize in the future, given recent litigation trends within the tort system and the inherent uncertainty in predicting the outcome of such trends. The Company will continue to monitor Bendix claim resolution values and other trends within the tort system to assess the appropriate look-back period for determining average resolution values going forward.

In 2023, the Company recognized a $522 million expense and corresponding adjustment to its estimated liability for Bendix asbestos-related claims. This amount includes $434 million attributable primarily to shortening the look-back period to the two most recent years, and to a lesser extent to increasing expected resolution values for a subset of asserted claims to adjust for higher claim values in that subset than in the modelled two-year data set.

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 the Company's 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 the Company's analysis of the underlying insurance policies, historical experience with insurers, ongoing review of the solvency of insurers, judicial determinations relevant to insurance programs, and consideration of the impacts of any settlements reached with the Company's insurers.

On October 31, 2018, David Kanefsky (Plaintiff), a Honeywell shareholder, filed a putative class action complaint in the U.S. District Court for the District of New Jersey (the Court) 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, the Company filed a Motion to Dismiss. On May 18, 2020, the Court denied the Motion to Dismiss. On December 7, 2021, the parties filed a Stipulation of Settlement (Settlement Agreement) and Plaintiff filed a motion for preliminary approval of the Settlement Agreement, which included payment by Honeywell of $10 million to settle the claims in dispute. On January 18, 2022, the Court approved the motion for preliminary approval of the Settlement Agreement. On May 3, 2022, the Court entered a final judgment and order approving the Settlement Agreement and dismissed the action. Honeywell continues to believe the claims lacked merit and has denied wrongdoing as well as any liability for the claims made against Honeywell in the action.

GARRETT LITIGATION AND BANKRUPTCY PROCEEDINGS

In conjunction with the Garrett spin-off, the Company entered into a binding indemnification and reimbursement agreement (Garrett Indemnity) and a binding tax matters agreement (Tax Matters Agreement) with Garrett and a Garrett subsidiary. On December 2, 2019, Garrett and Garrett ASASCO Inc. filed a Summons with Notice and commenced a lawsuit in the Commercial Division of the Supreme Court of the State of New York, County of New York (the State Court), seeking to invalidate the Garrett Indemnity. Garrett sought damages and a declaratory judgment based on various claims set forth in the Summons with Notice. On July 17, 2020, the Company received a notice from Garrett asserting that the Company had caused material breaches of the Tax Matters Agreement and that the Tax Matters Agreement was unenforceable.

On September 20, 2020, Garrett and 36 of its affiliates filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Southern District of New York (the Bankruptcy Court). On September 24, 2020, Garrett moved the existing State Court litigation against Honeywell to the Bankruptcy Court. For the year ended December 31, 2020, the Company reviewed the aggregate carrying value of the receivable amounts due in connection with the Garrett Indemnity and Tax Matters Agreement and reduced the aggregate carrying value of the receivable by $509 million to reflect the present value of the amounts owed to the Company over the full term of these agreements.

On April 26, 2021, the Bankruptcy Court confirmed Garrett’s amended Chapter 11 plan of reorganization (the Confirmed Plan), and on April 30, 2021 (the Effective Date), Garrett emerged from bankruptcy. On the Effective Date, and in accordance with the Confirmed Plan, (i) the Company received from Garrett an initial payment of $375 million and 834.8 million shares of Garrett's Series B Preferred Stock in full and final satisfaction of the Garrett Indemnity and Tax Matters Agreement, (ii) the Garrett Indemnity and Tax Matters Agreement were terminated, (iii) the Company and Garrett mutually released each other from the claims asserted in all pending legal actions related to the Garrett Indemnity and Tax Matters Agreement, and (iv) all pending litigation between the Company and Garrett in connection with those agreements was resolved.

The original Series B Preferred Stock Certificate of Designation provided for mandatory redemptions by Garrett of $35 million in 2022 and $100 million per year from 2023 to 2030 (inclusive) at the anniversary of the Effective Date, unless (i) Garrett’s consolidated EBITDA as of the end of the most recently completed fiscal year was less than $425 million, or (ii) Garrett did not have sufficient funds available to pay the redemption, at which point the redemption amounts past due would accrue interest. The Series B Preferred Stock Certificate of Designation also included rights which allowed (a) the Company to put the Series B Preferred Stock to Garrett if certain EBITDA conditions were met, and (b) Garrett to call the Series B Preferred Stock in whole or in part if certain EBITDA conditions were met.

On September 30, 2021, Garrett filed an Amended and Restated Series B Preferred Stock Certificate of Designation (Amendment) with the Secretary of State of Delaware. The Amendment required Garrett to partially redeem a portion of the Series B Preferred Stock on or before March 31, 2022, such that the present value of remaining outstanding shares of the Series B Preferred Stock would be $400 million (First Partial Redemption), subject to applicable law, including that Garrett had funds legally available for the partial redemption. The First Partial Redemption would be applied to the latest scheduled redemption dates, beginning with the shares to be redeemed in 2030. The Amendment also provided that the Company could not exercise its right to put the Series B Preferred Stock to Garrett until after December 31, 2022, subject to the EBITDA conditions described in the above section, unless the partial redemption did not occur on or before March 31, 2022. All other material terms and conditions in the Amendment were unchanged from the original Series B Preferred Stock Certificate of Designation.

On December 16, 2021, Garrett filed a Second Amended and Restated Series B Preferred Stock Certificate of Designation (Second Amendment) with the Secretary of State of Delaware. The Second Amendment accelerated the First Partial Redemption from March 31, 2022, to December 30, 2021, and allowed Garrett to partially redeem an additional portion of the Series B Preferred Stock on or before March 31, 2022, such that the present value of remaining outstanding shares of the Series B Preferred Stock would be $207 million (Second Partial Redemption). The Second Partial Redemption is subject to similar terms as the First Partial Redemption, including that Garrett had funds legally available for the partial redemption. However, the Second Partial Redemption was also contingent upon Garrett completing the First Partial Redemption and either (i) increasing their revolving credit facility, or (ii) the Garrett Board of Directors determining that Garrett otherwise had sufficient liquidity to effect the Second Partial Redemption. The Second Partial Redemption would be applied to the earliest scheduled redemptions beginning with the shares to be redeemed on April 30, 2022.

On December 17, 2021, Garrett announced their intention to effect the First Partial Redemption on December 28, 2021, in the amount of $211 million. On December 28, 2021, Garrett paid $211 million for the amount due as the First Partial Redemption.

On February 18, 2022, Garrett early redeemed $197 million of the Series B Preferred Stock, pursuant to the terms and conditions of the Second Amended and Restated Series B Preferred Stock Certificate of Designation. Immediately following the early redemption, the fair value of the Series B Preferred Stock was $207 million.

On June 28, 2022, Garrett early redeemed all remaining shares of the Series B Preferred Stock in the amount of $212 million, pursuant to the terms and conditions of the Second Amended and Restated Series B Preferred Stock Certificate of Designation. Following the redemption, the Series B Preferred Stock were no longer outstanding.

The Company recorded the Series B Preferred Stock at fair value at the Effective Date. See Note 12 Fair Value Measurements for additional information on the fair value leveling of the Series B Preferred Stock.

PETROBRAS AND UNAOIL MATTERS

On December 19, 2022, the Company reached a comprehensive resolution to the investigations by the U.S. Department of Justice (DOJ), the Securities and Exchange Commission (SEC), and certain Brazilian authorities (Brazilian Authorities) relating to the Company's use of third parties who previously worked for the Company's UOP business in Brazil in relation to a project awarded in 2010 for Petróleo Brasileiro S.A. (Petrobras). The investigations focused on the Company’s compliance with the U.S. Foreign Corrupt Practices Act and similar Brazilian laws (UOP Matters). The comprehensive resolution also resolves DOJ and SEC investigations relating to a matter involving a foreign subsidiary’s prior contract with Unaoil S.A.M. in Algeria executed in 2011 (the Unaoil Matter).

In connection with the comprehensive resolution, (i) the Company agreed to pay a total equivalent of $202.7 million, which payment occurred in January 2023, to the DOJ, the SEC, and the Brazilian Authorities, collectively, in penalties, disgorgement, and prejudgment interest, (ii) the Company’s subsidiary, UOP, LLC (UOP), entered into a three-year Deferred Prosecution Agreement (DPA) with the DOJ for charges related to the UOP Matters, (iii) UOP entered into leniency agreements with the Brazilian authorities related to the UOP Matter in Brazil, and (iv) the Company entered into an agreement with the SEC that resolves allegations relating to the UOP Matters and the Unaoil Matter. Pursuant to these agreements, the Company agreed to undertake certain compliance measures and compliance reporting obligations. These agreements entirely resolve the Petrobras and Unaoil investigations.

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 the Company's 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. The Company recognizes liabilities for any contingency that is probable of occurrence and reasonably estimable. The Company continually assesses the likelihood of adverse judgments or outcomes in such matters, as well as potential ranges of probable 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.

Given the uncertainty inherent in litigation and investigations, the Company does not believe it is possible to develop estimates of reasonably possible loss (or a range of possible loss) in excess of current accruals for commitment and contingency matters, including those discussed in this Note 19. Considering the Company's past experience and existing accruals, the Company does not expect the outcome of such matters, either individually or in the aggregate, to have a material adverse effect on the Company's 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 the Company to pay damage awards or settlements (or become subject to equitable remedies) that could have a material adverse effect on the Company's 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. The Company accrues 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 the Company's recorded obligations for product warranties and product performance guarantees:

PENSION AND OTHER POSTRETIREMENT BENEFITS

12 Months Ended

Dec. 31, 2023

Retirement Benefits [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 the Company's 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. The Company also sponsors 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 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 the Company's 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 the Company's 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:

1						The actuarial losses incurred in 2023 related to the Company's U.S. plans are primarily the result of a decrease in the discount rate assumption, as well as changes in demographic experience and demographic assumptions used to estimate the benefit obligations as of December 31, 2023, compared to December 31, 2022. Actuarial losses incurred in 2023 related to the Company's non-U.S. plans are primarily the result of a decrease in the discount rate assumption, partially offset by inflation related assumptions used to estimate the benefit obligations as of December 31, 2023, compared to December 31, 2022. Actuarial gains incurred in 2022 related to the Company's U.S. plans are primarily the result of an increase in the discount rate assumption, partially offset by changes in demographic experience and demographic assumptions used to estimate the benefit obligations as of December 31, 2022, compared to December 31, 2021. Actuarial gains incurred in 2022 related to the Company's non-U.S. plans are primarily the result of an increase in the discount rate assumption, partially offset by inflation related assumptions used to estimate the benefit obligations as of December 31, 2022, compared to December 31, 2021.

The discount rate for the Company's U.S. pension and other postretirement benefit 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 the Company's U.S. pension and other postretirement benefit plans, the Company uses a modeling process that involves matching the expected cash outflows of the Company's benefit plans to a yield curve constructed from a portfolio of high-quality, fixed income debt instruments. The Company uses the single weighted average yield of this hypothetical portfolio as a discount rate benchmark. The Company utilizes a full yield curve approach in the estimation of the service and interest cost components of net periodic pension benefit (income) for the Company's 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 the Company's U.S. pension plans, the single weighted average spot rates used to determine service and interest costs for 2024 are 5.06% and 4.89%, respectively. The discount rate used to determine the other postretirement benefit obligation is higher 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 7.00% for 2024, which represents an increase from the 6.75% assumption used for 2023. The Company's 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. The Company reviews the expected rate of return on an annual basis and revises 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
	2023		2022		2023		2022
Projected benefit obligation	$	251	$	255	$	753	$	682
Accumulated benefit obligation	249		253		736		664
Fair value of plan assets	—		—		249		230

The accumulated benefit obligation for the Company's U.S. defined benefit pension plans was $12.8 billion and $13.3 billion and for the Company's non-U.S. defined benefit pension plans was $4.7 billion and $4.4 billion at December 31, 2023, and 2022, respectively.

The Company's asset investment strategy for its U.S. pension plans focuses on maintaining a diversified portfolio using various asset classes in order to achieve the Company's long-term investment objectives on a risk adjusted basis. The Company's long-term target allocations are as follows: 45%-65% 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 inside 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 that follow several different strategies. The Company reviews its assets on a regular basis to ensure that the Company is 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 investment guidance. The Company's non-U.S. investment policies are different for each country as local regulations and financial and tax considerations are part of the funding and investment allocation process in each country.

In accordance with Accounting Standards Codification “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 the Company's pension plans to cover the notional value of the futures contracts. At December 31, 2023, and 2022, the Company's U.S. plans had contracts with notional amounts of $4,025 million and $2,567 million, respectively. At December 31, 2023, and 2022, the Company's non-U.S. plans had contracts with notional amounts of $124 million and $120 million, respectively. In both the Company's 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, mortgage/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 2023, 2022, and 2021, the Company was not required to make contributions to the U.S. pension plans and no contributions were made. The Company is not required to make any contributions to the U.S. pension plans in 2024. In 2023, contributions of $12 million were made to the non-U.S. pension plans to satisfy regulatory funding requirements. In 2024, the Company expects to make contributions of cash and/or marketable securities of approximately $12 million to the non-U.S. pension plans to satisfy regulatory funding standards. Contributions for both the 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:


	U.S. Plans		Non-U.S. Plans
2024	$	1,094	$	257
2025	1,077		253
2026	1,062		260
2027	1,044		266
2028	1,022		268
2029-2033	4,699		1,270

During the twelve months ended December 31, 2023, the Company repurchased $200 million of outstanding Honeywell shares of common stock from the Honeywell U.S. Pension Plan Master Trust. The Company completed no repurchases of outstanding Honeywell shares of common stock from the Honeywell U.S. Pension Plan Master Trust during 2022.

Leases [Abstract]

LEASES

A significant portion of the Company's operating and finance lease portfolio includes corporate offices, research and development facilities, manufacturing sites, information technology equipment, and automobiles. The majority of the Company's leases have remaining lease terms of 1 year to 20 years, some of which include options to extend the leases for 5 years or more. Operating lease ROU assets are included in Other assets. The current portion of operating lease liabilities are included in Accrued liabilities, and the non-current portion of operating lease liabilities are included in Other liabilities in the Consolidated Balance Sheet. Finance lease ROU assets are included in Property, plant and equipment—net. The current portion of finance lease liabilities are included in Current maturities of long-term debt, and the non-current portion of finance lease liabilities are included in Long-term debt in the Consolidated Balance Sheet.

A portion of the Company's real estate leases are generally subject to annual changes in the Consumer Price Index (CPI). The changes to the CPI are treated as variable lease payments and recognized in the period in which the obligation for those payments was incurred. In addition, a subset of the Company's automobile leases are considered variable. The variable lease payments for such automobile leases are based on actual mileage incurred at the stated contractual rate and recognized in the period in which the obligation for those payments was incurred.

See Note 22 Segment Financial Data for a summary by disaggregated product and services sales for each reportable business segment.

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 the Company's revenue based off timing of recognition is as follows:

CONTRACT BALANCES

The Company tracks progress on satisfying performance obligations under contracts with customers. The related billings and cash collections are recorded in 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 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. Contract 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 the Company 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:


	2023		2022
Contract assets—January 1	$	2,294	$	2,060
Contract assets—December 31	2,013		2,294
Change in contract assets—increase (decrease)	(281)		234
Contract liabilities—January 1	(4,583)		(4,290)
Contract liabilities—December 31	(4,326)		(4,583)
Change in contract liabilities—decrease (increase)	257		(293)
Net change	$	(24)	$	(59)

For the years ended December 31, 2023, and 2022, the Company recognized revenue of $2,070 million and $1,838 million, respectively, that was previously included in the beginning balance of contract liabilities.

Contract assets included $1,949 million and $2,265 million of unbilled balances under long-term contracts as of December 31, 2023, and 2022, respectively. These amounts are billed in accordance with the terms of customer contracts to which they relate.

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 the Company's measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct and at relative stand-alone selling price, they are accounted for as a new contract and performance obligation, which are recognized prospectively.

PERFORMANCE OBLIGATIONS

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. When the Company's contracts with customers require highly complex integration or manufacturing services that are not separately identifiable from other promises in the contracts and, therefore, not distinct, then the entire contract is accounted for as a single performance obligation. In situations when the Company's contracts include distinct goods or services that are substantially the same and have the same pattern of transfer to the customer over time, they are recognized as a series of distinct goods or services. For any contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation based on the estimated relative stand-alone 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 stand-alone 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 reportable business segment:


	December 31, 2023
Aerospace Technologies	$	13,898
Industrial Automation	6,227
Building Automation	7,302
Energy and Sustainability Solutions	4,303
Corporate and All Other1	47
Total performance obligations2	$	31,777


1						The remaining performance obligations within Corporate and All Other relate to the Quantinuum business.
2						Effective March 31, 2022, performance obligations exclude contracts with customers related to Russia as collectability is not reasonably assured.

Performance obligations recognized as of December 31, 2023 will be satisfied over the course of future periods. The Company's disclosure of the timing for satisfying the performance obligation is based on the requirements of contracts with customers. However, from time to time, these contracts may be subject to modifications, impacting the timing of satisfying the performance obligations. Performance obligations expected to be satisfied within one year and greater than one year are 60% and 40%, respectively.

The timing of satisfaction of the Company's performance obligations does not significantly vary from the typical timing of payment. Typical payment terms of the Company's fixed price over time contracts include progress payments based on specified events or milestones or based on project progress. For some contracts, the Company may be entitled to receive an advance payment.

The Company applied the practical expedient for certain revenue streams to exclude the value of remaining performance obligations for (i) contracts with an original expected term of one year or less or (ii) contracts for which the Company recognizes revenue in proportion to the amount the Company has the right to invoice for services performed.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.
