Item 8. Financial Statements and Supplementary Data

MANAGEMENT REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Illinois Tool Works Inc. (the "Company" or "ITW") is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). ITW's internal control system was designed to provide reasonable assurance to the Company's management and Board of Directors regarding the preparation and fair presentation of published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

ITW management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2021. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (2013). Based on our assessment we believe that, as of December 31, 2021, the Company's internal control over financial reporting is effective based on those criteria.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2021 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of Illinois Tool Works Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated statements of financial position of Illinois Tool Works Inc. and subsidiaries (the "Company") as of December 31, 2021 and 2020, the related consolidated statements of income, comprehensive income, changes in stockholders' equity, and cash flows, for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the "financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

Basis for Opinions

The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on these financial statements and an opinion on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the

financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Income Taxes — Refer to Note 7 to the financial statements

Critical Audit Matter Description

The Company's income tax expense is recognized and measured based on management's interpretation of the tax regulations and rulings in numerous taxing jurisdictions, which requires significant judgment. When calculating income tax expense management makes estimates and assumptions, including determination of the completeness of book income in each jurisdiction, calculation of taxable income through identification and classification of book to tax differences (either temporary or permanent items), consideration of applicable tax deductions or credits, and the identification of uncertain tax positions.

The evaluation of each uncertain tax position requires management to apply specialized skill and knowledge related to the identified position. Management evaluates uncertain tax positions identified and a liability is established for unrecognized tax benefits when there is a more than 50% likelihood that its tax position will not be sustained upon examination by taxing authorities. There is additional judgment to determine the amount of the liability for the underlying tax position. The Company's income tax expense for 2021 was $632 million and the liability recorded for unrecognized tax benefits as of December 31, 2021, was $360 million.

Given the number of taxing jurisdictions and the complex and subjective nature of the associated tax regulations and rulings, certain audit matters required a high degree of auditor judgment and increased extent of effort, including the need to involve our income tax specialists. These matters included the auditing of income tax expense, identification of uncertain tax positions, measurement of unrecognized tax benefits, and certain planning transactions with income tax expense implications.

How the Critical Audit Matter Was Addressed in the Audit

With the assistance of our income tax specialists, our principal audit procedures related to income tax expense included the following, among others:

• We tested the effectiveness of management's controls over income taxes, including those over income tax expense, unrecognized tax benefits, and certain planning transactions with income tax expense implications.

• We evaluated management's significant estimates and judgments incorporated into the calculation of income tax expense by:

◦Selecting a sample of book to tax differences (temporary and permanent) and testing the accuracy, completeness, and classification of the selections, including evaluating that all impacts of significant transactions with income tax expense implications are considered.

◦Developing an expectation over the foreign income tax expense by jurisdiction and comparing it to the recorded balance.

◦Testing the accuracy of the income tax expense calculation.

• We evaluated management's significant judgments regarding the identification of uncertain tax positions by:

◦Evaluating the reasonableness of a selection of certain planning transactions with income tax expense implications, including the completeness and accuracy of the underlying data supporting the transactions.

◦Assessing management's methods and assumptions used in identifying uncertain tax positions.

◦Comparing results of prior tax audits to ongoing and anticipated tax audits by tax authorities.

◦Evaluating external information including applicable tax law, new interpretations, and related changes to assess the completeness and reasonableness of management's considerations.

◦Determining if there was additional information not considered in management's assessment.

• We evaluated a sample of the liabilities recorded for unrecognized tax benefits to assess the establishment and amount of the liability for the specific underlying tax position.

Notes to Financial Statements

(1) Description of Business and Summary of Significant Accounting Policies

Description of business— Illinois Tool Works Inc. (the "Company" or "ITW") is a global manufacturer of a diversified range of industrial products and equipment with approximately 83 divisions in 52 countries. The Company's operations are organized and managed based on similar product offerings and end markets, and are reported to senior management as the following seven segments: Automotive OEM; Food Equipment; Test & Measurement and Electronics; Welding; Polymers & Fluids; Construction Products; and Specialty Products.

Consolidation and translation— The financial statements include the Company and its majority-owned subsidiaries. The Company follows the equity method of accounting for investments where the Company has a significant influence but not a controlling interest. Intercompany transactions are eliminated from the financial statements. Foreign subsidiaries' assets and liabilities are translated to U.S. dollars at end-of-period exchange rates. Revenues and expenses are translated at average rates for the period. Translation adjustments are reported as a component of accumulated other comprehensive income (loss) in stockholders' equity.

Reclassifications— Certain reclassifications of prior year data have been made to conform to current year reporting.

Use of estimates— The preparation of the Company's financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the notes to financial statements. Actual results could differ from those estimates.

Acquisitions— The Company accounts for acquisitions under the acquisition method, in which assets acquired and liabilities assumed are recorded at fair value as of the date of acquisition. The operating results of the acquired companies are included in the Company's consolidated financial statements from the date of acquisition. Refer to Note 3. Acquisitions for additional information regarding the Company's acquisitions.

Operating revenue— Operating revenue is recognized at the time a good or service is transferred to a customer and the customer obtains control of that good or receives the service performed. The Company's sales arrangements with customers are predominantly short-term in nature involving a single performance obligation related to the delivery of products and generally provide for transfer of control at the time of shipment. In limited circumstances, there may be significant obligations to the customer that are unfulfilled at the time of shipment, typically involving installation of equipment and customer acceptance. In these circumstances, operating revenue may be deferred until all significant obligations have been completed. In other limited arrangements, the Company may recognize revenue over time. This may include arrangements for service performed over time where operating revenue is recognized over time as the service is provided to the customer. It may also include the sale of highly specialized systems that include a high degree of customization and installation at the customer site which are recognized over time if the product does not have an alternative use and the Company has an enforceable right to payment for work performed to date. Revenue for transactions meeting these criteria is recognized over time as work is performed based on the costs incurred to date relative to the total estimated costs at completion. The amount of operating revenue recorded reflects the consideration to which the Company expects to be entitled in exchange for goods or services and may include adjustments for customer allowances and rebates. Customer allowances and rebates consist primarily of volume discounts and other short-term incentive programs, which are estimated at the time of sale based on historical experience and anticipated trends. Shipping and handling charges billed to customers are included in revenue and are recognized along with the related product revenue as they are considered a fulfillment cost. Sales commissions are expensed when incurred, which is generally at the time of revenue recognition. Contract liabilities associated with sales arrangements primarily relate to deferred revenue on equipment sales and prepaid service contracts. Total deferred revenue and customer deposits were $394 million and $222 million as of December 31, 2021 and 2020, respectively, and are short-term in nature. The deferred revenue and customer deposits as of December 31, 2021 included $108 million related to the MTS Test & Simulation business, which was acquired on December 1, 2021. Refer to Note 3. Acquisitions for additional information regarding this acquisition. Refer to Note 5. Operating Revenue for additional information regarding the Company's operating revenue.

Research and development expenses— Research and development expenses are recorded as expense in the year incurred. These costs were $239 million, $214 million and $221 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Advertising expenses— Advertising expenses are recorded as expense in the year incurred. These costs were $50 million, $43 million and $48 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Income taxes— The Company utilizes the asset and liability method of accounting for income taxes. Deferred income taxes are determined based on the estimated future tax effects of differences between the financial and tax bases of assets and liabilities given the provisions of the enacted tax laws. Valuation allowances are established when it is estimated that it is more likely than not that the tax benefit of the deferred tax asset will not be realized.

Cash and equivalents— Cash and equivalents include cash on hand and instruments having original maturities of three months or less. Cash and equivalents are stated at cost, which approximates fair value.

Trade receivables— Trade receivables are net of allowances for doubtful accounts. The changes in the allowance for doubtful accounts for the years ended December 31, 2021, 2020 and 2019 were as follows:

In millions			2021						2020						2019
Beginning balance			$	29					$	20					$	21
Provision charged to expense			3						7						6
Acquisitions and divestitures			2						—						—
Write-offs, net of recoveries			(5)						(4)						(4)
Transfer (to)/from assets held for sale			—						2						(2)
Foreign currency translation/other			(1)						4						(1)
Ending balance			$	28					$	29					$	20

Inventories— Inventories are stated at the lower of cost or net realizable value and include material, labor and factory overhead. The last-in, first-out ("LIFO") method is used to determine the cost of inventories at certain U.S. businesses. The first-in, first-out ("FIFO") method, which approximates current cost, is used for all other inventories. Inventories priced at LIFO were approximately 19% of total inventories as of both December 31, 2021 and 2020. If the FIFO method was used for all inventories, total inventories would have been approximately $118 million and $82 million higher than reported at December 31, 2021 and 2020, respectively. The major classes of inventory at December 31, 2021 and 2020 were as follows:

In millions			2021						2020
Raw material			$	716					$	454
Work-in-process			208						136
Finished goods			888						681
LIFO reserve			(118)						(82)
Total inventories			$	1,694					$	1,189

Net plant and equipment— Net plant and equipment are stated at cost, less accumulated depreciation. Renewals and improvements that increase the useful life of plant and equipment are capitalized. Maintenance and repairs are charged to expense as incurred. Net plant and equipment consisted of the following at December 31, 2021 and 2020:

In millions			2021						2020
Land			$	198					$	204
Buildings and improvements			1,462						1,432
Machinery and equipment			3,898						3,824
Construction in progress			142						133
Gross plant and equipment			5,700						5,593
Accumulated depreciation			(3,891)						(3,816)
Net plant and equipment			$	1,809					$	1,777

The Company's U.S. businesses primarily compute depreciation on an accelerated basis. The majority of the Company's international businesses compute depreciation on a straight-line basis. The ranges of useful lives used to depreciate plant and equipment are as follows:

Buildings and improvements			5—50 years
Machinery and equipment			3—12 years

Depreciation was $277 million, $273 million and $267 million for the years ended December 31, 2021, 2020 and 2019, respectively.

Goodwill and intangible assets— Goodwill represents the excess cost over fair value of the net assets of acquired businesses. The Company does not amortize goodwill and intangible assets that have indefinite lives. Amortizable intangible assets are being amortized on a straight-line basis over their estimated useful lives of 3 to 20 years.

The Company performs an impairment assessment of goodwill and intangible assets with indefinite lives annually, or more frequently if triggering events occur, based on the estimated fair value of the related reporting unit or intangible asset. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.

When performing its annual impairment assessment, the Company evaluates the goodwill assigned to each of its reporting units for potential impairment by comparing the estimated fair value of the relevant reporting unit to the carrying value. The Company uses various Level 2 and Level 3 valuation techniques to determine the fair value of its reporting units, including discounting estimated future cash flows based on a cash flow forecast prepared by the relevant reporting unit and market multiples of relevant public companies. If the fair value of a reporting unit is less than its carrying value, a goodwill impairment loss is recorded for the difference.

The Company's indefinite-lived intangible assets consist of trademarks and brands. The estimated fair values of these intangible assets are determined based on a Level 3 valuation method using a relief-from-royalty income approach derived from internally forecasted revenues of the related products. If the fair value of the trademark or brand is less than its carrying value, an impairment loss is recorded for the difference between the estimated fair value and carrying value of the intangible asset.

Leases— The Company recognizes a lease liability and corresponding right-of-use asset for all operating leases with a noncancellable lease term of greater than one year. Rental expense for operating leases is recognized on a straight-line basis over the noncancellable lease term based on the minimum lease payments at lease inception. Changes in rent subsequent to commencement that were not included in minimum lease payments at inception are recognized as variable rent in the period incurred. Refer to Note 10. Leases for additional information regarding the Company's operating leases.

Accrued warranties— The Company accrues for product warranties based on historical experience. The changes in accrued warranties for the years ended December 31, 2021, 2020 and 2019 were as follows:

In millions			2021						2020						2019
Beginning balance			$	45					$	45					$	45
Charges			(34)						(34)						(44)
Provision charged to expense			34						33						44
Acquisitions and divestitures			5						—						—
Foreign currency translation/other			(4)						1						—

In June 2016, the Financial Accounting Standards Board (the "FASB") issued authoritative guidance which changes the methodology used to measure credit losses for certain financial instruments. Under prior guidance, credit loss reserves were estimated based on historical information. The new guidance requires credit loss reserves to reflect the estimated credit losses expected to be incurred over the life of the financial asset. The Company adopted this new guidance effective January 1, 2020

and applied it prospectively, which did not have a material impact on the Company's results of operations or financial position.

In January 2017, the FASB issued authoritative guidance which simplifies the assessment of goodwill for impairment. Under prior guidance, when the estimated fair value of a reporting unit was less than its carrying value, the fair value of the goodwill was determined by valuing the other assets and liabilities of the reporting unit. Under the new guidance, the requirement to determine the fair value of goodwill has been eliminated, and an impairment charge is recognized for the amount that the carrying value of the reporting unit exceeds its fair value. Effective January 1, 2020, the Company adopted the new guidance prospectively and applied the new guidance during its annual assessment of goodwill in the third quarter of 2020 and 2021. The adoption of this new accounting guidance had no impact on the Company's results of operations or financial position. Refer to Note 9. Goodwill and Intangible Assets for additional information regarding the Company's annual assessment of goodwill.

In December 2019, the FASB issued authoritative guidance which simplifies certain aspects of the accounting for income taxes, including the elimination of an exception to the methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated full year loss. The Company early adopted this new guidance effective January 1, 2020 and applied it prospectively, which did not have a material impact on the Company's results of operations or financial position.

In October 2021, the FASB issued authoritative guidance which improves the accounting for acquired revenue contracts with customers in a business combination. The new guidance provides an exception to measure contract assets and contract liabilities acquired in a business combination in accordance with existing revenue recognition guidance rather than at fair value. The Company early adopted this new guidance in the fourth quarter of 2021. The new guidance is effective prospectively upon adoption and must also be applied retrospectively to all interim periods in the year of adoption. The adoption of this new accounting guidance did not have a material impact on the Company's results of operations or financial position. Refer to Note 3. Acquisitions for additional information regarding the Company's acquisitions.

(2) Novel Coronavirus (COVID-19)

In early 2020, an outbreak of a novel strain of coronavirus ("COVID-19") occurred in China and other jurisdictions. The COVID-19 outbreak was subsequently declared a global pandemic by the World Health Organization on March 11, 2020. In response to the outbreak, governments around the globe have taken various actions to reduce its spread, including travel restrictions, shutdowns of businesses deemed nonessential, and stay-at-home or similar orders. The COVID-19 pandemic and the measures taken globally to reduce its spread have negatively impacted the global economy, causing significant disruptions in the Company's global operations starting primarily in the latter part of the first quarter of 2020 as COVID-19 continued to spread and impact the countries in which the Company operates and the markets the Company serves. During 2021, the Company experienced solid recovery progress in many of its end markets; however, the disruptions caused by the COVID-19 pandemic continue to have an adverse impact on the Company's global operations. The full extent of the COVID-19 outbreak and its impact on the markets served by the Company and on the Company's operations continues to be highly uncertain as conditions continue to fluctuate around the world, with vaccine administration rising in certain regions and spikes in infections (including the spread of variants) also being experienced. A prolonged outbreak could continue to interrupt the operations of the Company and its customers and suppliers.

(3) Acquisitions

Net cash paid for acquisitions during 2021 and 2019 was $731 million and $4 million, respectively. There were no acquisitions in 2020. The cash paid in 2021 related to the acquisition of the Test & Simulation business of MTS Systems Corporation ("MTS") from Amphenol Corporation ("Amphenol"), as discussed below. Acquisitions, individually and in the aggregate, did not materially affect the Company's results of operations or financial position for any period presented.

On December 1, 2021, the Company completed the acquisition of the MTS Test & Simulation business for a purchase price of $750 million, subject to certain closing adjustments. The MTS Test & Simulation business is a leading global supplier of high-performance testing and simulation systems and is highly complementary to the Company's existing Test & Measurement and Electronics segment. The operating results of the MTS Test & Simulation business were reported within the Test & Measurement and Electronics segment from the date of acquisition, with operating revenue of $46 million for the one month ended December 31, 2021. The Company is in process of allocating the purchase price to the acquired assets and liabilities as of the acquisition date, including intangible assets and goodwill. Based on its initial allocation, the Company recorded goodwill of $371 million and intangible assets of $321 million. The intangible assets included $93 million related to

indefinite-lived trademarks and brands and $228 million related to amortizable intangible assets that are expected to be amortized on a straight-line basis over estimated useful lives ranging from 0.3 to 12 years, with a weighted-average life of 10 years. The Company does not expect any of the goodwill related to the transaction to be tax deductible. The fair values of the intangible assets were estimated based on discounted cash flow and market-based valuation models using Level 2 and Level 3 inputs and assumptions. Subsequent acquisition accounting adjustments may change the initial amounts recorded, including goodwill and intangible assets, primarily due to the completion of valuations. The allocation of purchase price will be completed as soon as practicable, but no later than one year from the acquisition date.

(4) Divestitures

The Company routinely reviews its portfolio of businesses relative to its business portfolio criteria and evaluates if further portfolio refinements may be needed. The Company previously communicated its intent to explore options, including potential divestitures, for certain businesses with annual revenues totaling up to $1 billion. As such, the Company may commit to a plan to exit or dispose of certain businesses and present them as held for sale in periods prior to the sale of the business.

In the second quarter of 2019, the Company approved plans to divest six businesses, including two businesses in the Test & Measurement and Electronics segment, one business in the Automotive OEM segment, one business in the Welding segment, and two businesses in the Specialty Products segment. These six businesses were classified as held for sale beginning in the second quarter of 2019. In the fourth quarter of 2019, the Company divested three of the held for sale businesses which included one business in the Test & Measurement and Electronics segment, one business in the Welding segment, and one business in the Specialty Products segment.

For the twelve months ended December 31, 2019, the Company recorded net pre-tax gains on disposal of businesses of $44 million ($30 million after-tax, or $0.09 per diluted share) which was primarily due to the three divestitures of held for sale businesses discussed above. The net pre-tax gain was included in Other income (expense) in the Statement of Income.

Operating revenue related to businesses divested in 2019 that was included in the Company's results of operations for the twelve months ended December 31, 2019 was $134 million. The operating revenue for the twelve months ended December 31, 2019 of $134 million related to the businesses divested in 2019 included $62 million in the Welding segment, $58 million in the Test & Measurement and Electronics segment, and $14 million in the Specialty Products segment.

As of December 31, 2019, three of the businesses discussed above continued to be held for sale, including one business in the Test & Measurement and Electronics segment, one business in the Automotive OEM segment, and one business in the Specialty Products segment.

During 2020, the sales of the three remaining businesses held for sale were determined to no longer be probable of being completed within one year, primarily due to the disruptions and economic uncertainty resulting from the COVID-19 pandemic. Accordingly, these businesses were no longer presented as held for sale.

(5) Operating Revenue

The Company's 83 diversified operating divisions are organized and managed based on similar product offerings and end markets, and are reported to senior management as the following seven segments: Automotive OEM; Food Equipment; Test & Measurement and Electronics; Welding; Polymers & Fluids; Construction Products; and Specialty Products. Operating revenue by product category, which is consistent with the Company's segment presentation, for the twelve months ended December 31, 2021, 2020 and 2019 was as follows:

Intersegment revenue			(22)						(17)						(20)
Total			$	14,455					$	12,574					$	14,109

The following is a description of the product offerings, end markets and typical revenue transactions for each of the Company's seven segments:

Automotive OEM**—** This segment is a global, niche supplier to top tier OEMs, providing unique innovation to address pain points for sophisticated customers with complex problems. Businesses in this segment produce components and fasteners for automotive-related applications. This segment primarily serves the automotive original equipment manufacturers and tiers market. Products in this segment include:

• plastic and metal components, fasteners and assemblies for automobiles, light trucks and other industrial uses.

Products sold in this segment are primarily manufactured to the customer's specifications and are sold under long-term supply agreements with OEM auto manufacturers and other top tier auto parts suppliers. The Company typically recognizes revenue for products in this segment at the time of shipment. Certain products may be produced utilizing tooling that is owned by the customer that the Company developed and is reimbursed by the customer for the associated cost. In these arrangements, the Company typically retains a contractual right to use the customer-owned tooling for the purpose of fulfilling its obligations under the supply agreement. The Company records reimbursements for the cost of customer-owned tooling as a cost offset rather than operating revenue as tooling is not considered a product offering central to the Company's operations.

Food Equipment**—** This segment is a highly focused and branded industry leader in commercial food equipment differentiated by innovation and integrated service offerings. This segment primarily serves the food service, food retail and food institutional/restaurant markets. Products in this segment include:

(6) Other Income (Expense)

Other income (expense) for the twelve months ended December 31, 2021, 2020 and 2019 consisted of the following:

In millions			2021						2020						2019
Interest income			$	12					$	17					$	29
Other net periodic benefit income			23						13						24
Income (loss) from investments			29						8						15
Gain (loss) on disposal of operations and affiliates			—						—						44
Equity income in Wilsonart			—						—						—
Gain (loss) on foreign currency transactions, net			(9)						(5)						(10)
Other, net			(4)						(5)						5
Total other income (expense)			$	51					$	28					$	107

Refer to Note 4. Divestitures for further information regarding the Gain (loss) on disposal of operations and affiliates of $44 million for the twelve months ended December 31, 2019.

In the fourth quarter of 2012, the Company divested a 51% majority interest in its former Decorative Surfaces segment to certain funds managed by Clayton, Dubilier & Rice, LLC ("CD&R"). As a result of the transaction, the Company owns common units (the "Common Units") of Wilsonart International Holdings LLC ("Wilsonart") initially representing approximately 49% (on an as-converted basis) of the total outstanding equity. CD&R owns cumulative convertible participating preferred units (the "Preferred Units") of Wilsonart representing approximately 51% (on an as-converted basis) of the total outstanding equity. The Preferred Units rank senior to the Common Units as to dividends and liquidation preference, and accrue dividends at a rate of 10% per annum. The ownership interest in Wilsonart is reported using the equity method of accounting. The Company's proportionate share in the income (loss) of Wilsonart is reported in Other income (expense) in the Statement of Income. As the Company's investment in Wilsonart is structured as a partnership for U.S. tax purposes, U.S. taxes are recorded separately from the equity investment. In 2016, the Company received a $167 million dividend distribution from Wilsonart which exceeded the Company's equity investment balance and resulted in a $54 million pre-tax gain in 2016. As a result of the dividend distribution, the equity investment balance in Wilsonart was reduced to zero and any subsequent equity investment income will not be recognized until the gain is recaptured.

(7) Income Taxes

Noncurrent income taxes payable— On December 22, 2017, the "Tax Cuts and Jobs Act" (the "Act") was enacted in the United States. The provisions of the Act significantly revised the U.S. corporate income tax rules. In connection with the

enactment of the Act, the Company recorded a one-time additional income tax expense of $676 million in the fourth quarter of 2017 related to a one-time repatriation tax on the deemed repatriation of post-1986 undistributed earnings of foreign subsidiaries. A portion of the resulting income taxes payable can be paid in installments over eight years. The noncurrent income taxes payable related to the one-time repatriation tax was $365 million and $413 million as of December 31, 2021 and 2020, respectively.

Provision for income taxes— The components of the provision for income taxes for the twelve months ended December 31, 2021, 2020 and 2019 were as follows:

In millions			2021						2020						2019
U.S. federal income taxes:

Total state income taxes			83						57						82
Total provision for income taxes			$	632					$	595					$	767

Income before taxes for domestic and foreign operations for the twelve months ended December 31, 2021, 2020 and 2019 was as follows:

In millions			2021						2020						2019
Domestic			$	1,667					$	1,419					$	1,774
Foreign			1,659						1,285						1,514
Total income before taxes			$	3,326					$	2,704					$	3,288

The reconciliation between the U.S. federal statutory tax rate and the effective tax rate for the twelve months ended December 31, 2021, 2020 and 2019 was as follows:

			2021						2020						2019
U.S. federal statutory tax rate			21.0		%				21.0		%				21.0		%
U.S. tax effect of foreign earnings			1.2						1.0						1.1
Changes in tax law			(3.4)						(1.5)						—
State income taxes, net of U.S. federal tax benefit			2.1						1.9						1.7
Differences between U.S. federal statutory and foreign tax rates			1.9						2.0						2.0
Nontaxable foreign interest income			(1.6)						(2.0)						(1.4)
Tax effect of foreign dividends			0.6						1.6						0.2
Foreign derived intangible income			(1.3)						(1.3)						(0.1)
Excess tax benefits from stock-based compensation			(0.5)						(1.0)						(0.9)
Other, net			(1.0)						0.3						(0.3)
Effective tax rate			19.0		%				22.0		%				23.3		%

The Company's effective tax rate for the twelve months ended December 31, 2021, 2020 and 2019 was 19.0%, 22.0% and 23.3%, respectively. The 2021 effective tax rate benefited from discrete income tax benefits of $21 million in the third quarter of 2021 related to the utilization of capital losses and $112 million in the second quarter of 2021 related to the

remeasurement of net deferred tax assets due to the enactment of the U.K. Finance Bill 2021, which increases the U.K. income tax rate from 19% to 25% effective April 1, 2023. The 2019 effective tax rate benefited from a discrete income tax benefit of $21 million in the third quarter for the U.S. federal provision to return adjustment resulting primarily from changes in estimates related to the Act. Additionally, the effective tax rates for 2021, 2020 and 2019 included discrete income tax benefits of $17 million, $27 million and $28 million, respectively, related to excess tax benefits from stock-based compensation.

Upon repatriation of foreign earnings to the U.S., the Company may be subject to foreign withholding taxes. The accrual for foreign withholding taxes related to the expected repatriation of foreign held cash and equivalents as of December 31, 2021 and 2020 was $48 million and $55 million, respectively.

Deferred foreign withholding taxes have not been provided on undistributed earnings considered permanently invested. As of December 31, 2021, undistributed earnings of certain international subsidiaries that are considered permanently invested were approximately $6 billion. Determination of the related deferred tax liability is not practicable because of the complexities associated with the hypothetical calculation.

Deferred tax assets and liabilities— The components of deferred income tax assets and liabilities as of December 31, 2021 and 2020 were as follows:

			2021												2020
In millions			Asset						Liability						Asset						Liability

Valuation allowances			(644)						—						(427)						—
Total deferred income tax assets (liabilities)			$	884					$	(986)					$	764					$	(819)

The valuation allowances recorded as of December 31, 2021 and 2020 related primarily to certain net operating loss carryforwards and capital loss carryforwards. As of December 31, 2021, the Company had utilized all realizable foreign tax credit carryforwards.

As of December 31, 2021, the Company had net operating loss carryforwards available to offset future taxable income in the U.S. and certain foreign jurisdictions, which expire as follows:

			Gross Carryforwards
			Related to Net
In millions			Operating Losses
2022			$	19
2023			5
2024			9
2025			2
2026			9
2027-2047			574
Do not expire			1,116
Total gross carryforwards related to net operating losses			$	1,734

Unrecognized tax benefits— The changes in the amount of unrecognized tax benefits for the twelve months ended December 31, 2021, 2020 and 2019 were as follows:

In millions			2021						2020						2019
Beginning balance			$	346					$	296					$	297
Additions based on tax positions related to the current year			11						74						6
Additions for tax positions of prior years			23						39						13
Reductions for tax positions of prior years			(12)						(47)						(14)
Settlements			—						(23)						(5)
Foreign currency translation			(8)						7						(1)
Ending balance			$	360					$	346					$	296

Included in the balance as of December 31, 2021 were approximately $320 million of unrecognized tax benefits that, if recognized, would impact the Company's effective tax rate.

The Company and its subsidiaries file tax returns in the U.S. and various state, local and foreign jurisdictions. These tax returns are routinely audited by the tax authorities in these jurisdictions including the Internal Revenue Service, Her Majesty's Revenue and Customs, German Fiscal Authority, French Fiscal Authority, and Australian Tax Office, and a number of these audits are currently ongoing, which may increase the amount of the unrecognized tax benefits in future periods. The Company believes it is reasonably possible that within the next twelve months the amount of the Company's unrecognized tax benefits may be decreased by approximately $51 million related predominantly to the potential resolution of federal, state and foreign examinations. The Company has recorded its best estimate of the potential exposure for these issues. The following table summarizes the open tax years for the Company's major jurisdictions:

Jurisdiction			Open Tax Years
United States – Federal			2017-2021
United Kingdom			2017-2021
Germany			2015-2021
France			2017-2021
Australia			2013-2021

The Company recognizes interest and penalties related to income tax matters in income tax expense. The accrual for interest and penalties as of December 31, 2021 and 2020 was $40 million and $34 million, respectively.

(8) Net Income Per Share

Net income per basic share is computed by dividing net income by the weighted-average number of shares outstanding for the period. Net income per diluted share is computed by dividing net income by the weighted-average number of shares

assuming dilution for stock options and restricted stock units. Dilutive shares reflect the potential additional shares that would be outstanding if the dilutive stock options outstanding were exercised and the unvested restricted stock units vested during the period. The computation of net income per share for the twelve months ended December 31, 2021, 2020 and 2019 was as follows:

In millions except per share amounts			2021						2020						2019
Net Income			$	2,694					$	2,109					$	2,521
Net income per share—Basic:
Weighted-average common shares			315.1						316.9						323.9
Net income per share—Basic			$	8.55					$	6.66					$	7.78
Net income per share—Diluted:
Weighted-average common shares			315.1						316.9						323.9
Effect of dilutive stock options and restricted stock units			1.3						1.4						1.7
Weighted-average common shares assuming dilution			316.4						318.3						325.6
Net income per share—Diluted			$	8.51					$	6.63					$	7.74

Options that were considered antidilutive were not included in the computation of diluted net income per share. There were 0.4 million, 0.5 million and 0.9 million antidilutive options outstanding for the twelve months ended December 31, 2021, 2020 and 2019, respectively.

(9) Goodwill and Intangible Assets

The changes in the carrying amount of goodwill for the twelve months ended December 31, 2021 and 2020 were as follows:

In millions			Automotive OEM						Test & Measurement and Electronics						Food Equipment						Polymers & Fluids						Welding						Construction Products						Specialty Products						Total
Balance, December 31, 2019			$	466					$	1,245					$	256					$	887					$	258					$	512					$	868					$	4,492

(12) Pension and Other Postretirement Benefits

The Company has both funded and unfunded defined benefit pension and other postretirement benefit plans, predominately in the U.S. The U.S. primary pension plan provides benefits based on years of service and final average salary. The U.S. primary postretirement health care plan is contributory with the participants' contributions adjusted annually. The U.S. primary postretirement life insurance plan is noncontributory. Beginning January 1, 2007, the U.S. primary pension and other postretirement benefit plans were closed to new participants. Newly hired employees and employees from acquired businesses that are not participating in these plans are eligible for additional Company contributions under the existing U.S. primary defined contribution retirement plans. The Company's expense related to defined contribution plans was $88 million in 2021, $85 million in 2020, and $86 million in 2019. In addition to the U.S. plans, the Company also has defined benefit pension plans in certain other countries, mainly the United Kingdom, Canada, Germany and Switzerland.

Summarized information regarding net periodic benefit cost included in the Statement of Income related to the Company's significant defined benefit pension and other postretirement benefit plans for the twelve months ended December 31, 2021, 2020 and 2019 is as follows:

As of December 31, 2021 and 2020, pension plans with projected benefit obligations in excess of plan assets had projected benefit obligations of $232 million and $212 million, respectively, and plan assets of $59 million and $32 million, respectively. As of December 31, 2021 and 2020, pension plans with accumulated benefit obligations in excess of plan assets had accumulated benefit obligations of $223 million and $205 million, respectively, and plan assets of $59 million and $32 million, respectively.

Assumptions— The weighted-average assumptions used in the valuations of pension and other postretirement benefits were as follows:

			Pension																		Other Postretirement Benefits
			2021						2020						2019						2021						2020						2019
Assumptions used to determine benefit obligations as of December 31:
Discount rate			2.33		%				1.89		%				2.61		%				2.92		%				2.59		%				3.29		%
Rate of compensation increases			3.40		%				3.24		%				3.44		%
Interest crediting rate - U.S. cash balance plan			3.75		%				3.75		%				4.00 %
Assumptions used to determine net periodic benefit cost for the twelve months ended December 31:
Discount rate			1.89		%				2.61		%				3.66		%				2.59		%				3.29		%				4.40		%
Expected return on plan assets			3.67		%				4.33		%				4.71		%				6.65		%				6.70		%				6.70		%
Rate of compensation increases			3.24		%				3.44		%				3.52		%
Interest crediting rate - U.S. cash balance plan			3.75		%				4.00 %						4.00 %

The expected long-term rates of return for pension and other postretirement benefit plans were developed using historical asset class returns while factoring in current market conditions such as inflation, interest rates and asset class performance.

The discount rate reflects the current rate at which the associated liabilities could theoretically be effectively settled at the end of the year. In estimating this rate, the Company looks at rates of return on high-quality fixed income investments, with similar duration to the liabilities in the plan. The Company estimates the service and interest cost components of net periodic benefit cost by applying specific spot rates along the yield curve to the projected cash flows rather than a single weighted-average rate.

Assumed health care cost trend rates have an effect on the amounts reported for the postretirement health care benefit plans. The assumed health care cost trend rates used to determine the postretirement benefit obligation as of December 31 were as follows:

			2021						2020						2019
Health care cost trend rate assumed for the next year			7.00		%				7.00		%				6.70		%
Ultimate trend rate			4.50		%				4.50		%				4.50		%
Year the rate reaches the ultimate trend rate			2029						2027						2026

Plan assets— The Company's overall investment strategy for the assets in the pension funds is to achieve a balance between the goals of growing plan assets and keeping risk at a reasonable level over a long-term investment horizon. In order to reduce unnecessary risk, the pension funds are diversified across several asset classes, securities and investment managers. The target allocations for plan assets are 15% to 25% equity investments, 75% to 85% fixed income investments and 0% to 10% in other types of investments. The Company does not use derivatives for the purpose of speculation, leverage, circumventing investment guidelines or taking risks that are inconsistent with specified guidelines.

The assets in the Company's postretirement health care plan are primarily invested in life insurance policies. The Company's overall investment strategy for the assets in the postretirement health care fund is to invest in assets that provide a reasonable tax exempt rate of return while preserving capital.

The following tables present the fair value of the Company's pension and other postretirement benefit plan assets as of December 31, 2021 and 2020, by asset category and valuation methodology. Level 1 assets are valued using unadjusted quoted prices for identical assets in active markets. Level 2 assets are valued using quoted prices or other observable inputs for similar assets. Level 3 assets are valued using unobservable inputs, but reflect the assumptions market participants would be expected to use in pricing the assets. Each financial instrument's categorization is based on the lowest level of input that is significant to the fair value measurement.

Cash and equivalents include cash on hand and instruments with original maturities of three months or less and are valued at cost, which approximates fair value. Fixed income securities primarily consist of U.S. and foreign government bills, notes and bonds, corporate debt securities and investment contracts. The majority of the assets in this category are valued by evaluating bid prices provided by independent financial data services. For securities where market data is not readily available, unobservable market data is used to value the security.

Pension assets measured at net asset value include mutual funds, collective trust funds, partnerships/private equity interests and life insurance policies. Mutual funds and collective trust funds are funds that are valued based on the value of the underlying investments which can be redeemed on a daily basis. The underlying investments include both passively and actively managed U.S. and foreign large- and mid-cap equity funds and short-term investment funds. Partnerships/private equity interests are investments in partnerships where the benefit plan is a limited partner. The investments are valued by the investment managers on a periodic basis using pricing models that use market, income and cost valuation methods. Distributions are received from these funds on a periodic basis through the liquidation of the underlying assets of the fund. Life insurance policies are used to fund other postretirement benefits in order to obtain favorable tax treatment and are valued

based on the cash surrender value of the underlying policies. The Company has selected the funds in which these assets are invested and may elect to withdraw funds with proper notice to the insurance company or maintain the policies and receive death benefits as determined by the contracts.

Cash flows— The Company generally funds its pension and other postretirement benefit plans as required by law or to the extent such contributions are tax deductible. The Company expects to contribute approximately $14 million to its pension plans and $4 million to its other postretirement benefit plans in 2022. As of December 31, 2021, the Company's portion of the future benefit payments that are expected to be paid during the twelve months ending December 31 is as follows:

(13) Commitments and Contingencies

The Company is subject to various legal proceedings and claims that arise in the ordinary course of business, including those involving environmental, product liability (including toxic tort) and general liability claims. The Company accrues for such liabilities when it is probable that future costs will be incurred and such costs can be reasonably estimated. Such accruals are based on developments to date, the Company's estimates of the outcomes of these matters and its experience in contesting, litigating and settling other similar matters. The Company believes resolution of these matters, individually and in the aggregate, will not have a material adverse effect on the Company's financial position, liquidity or future operations.

In millions			2021						2020						2019
Beginning balance			$	(1,642)					$	(1,705)					$	(1,677)
Foreign currency translation adjustments during the period			73						(82)						7
Foreign currency translation adjustments reclassified to income			5						—						—
Income taxes			(73)						86						(9)
Total foreign currency translation adjustments, net of tax			5						4						(2)
Pension and other postretirement benefit adjustments during the period			125						30						(54)
Pension and other postretirement benefit adjustments reclassified to income			54						48						21
Income taxes			(44)						(19)						7
Total pension and other postretirement benefit adjustments, net of tax			135						59						(26)
Ending balance			$	(1,502)					$	(1,642)					$	(1,705)

Foreign currency translation adjustments reclassified to income primarily relate to the exit of immaterial foreign operations. Pension and other postretirement benefit adjustments reclassified to income represent the amortization of actuarial gains and losses and prior service cost. Refer to Note 12. Pension and Other Postretirement Benefits for the amounts included in net periodic benefit cost.

The Company designated the €1.0 billion of Euro notes issued in May 2014, the €1.0 billion of Euro notes issued in May 2015 and the €1.6 billion of Euro notes issued in June 2019 as hedges of a portion of its net investment in Euro-denominated foreign operations to reduce foreign currency risk associated with the investment in these operations. Changes in the value of this debt resulting from fluctuations in the Euro to U.S. Dollar exchange rate have been recorded as foreign currency translation adjustments within Accumulated other comprehensive income (loss). The cumulative unrealized pre-tax gain (loss) recorded in Accumulated other comprehensive income (loss) related to the net investment hedge was a gain of $183 million as of December 31, 2021 and a loss of $120 million as of December 31, 2020.

As of December 31, 2021 and 2020, the ending balance of Accumulated other comprehensive income (loss) consisted of after-tax cumulative translation adjustment losses of $1.3 billion and $1.3 billion, respectively, and after-tax unrecognized pension and other postretirement benefits costs of $196 million and $331 million, respectively.

(15) Stock-Based Compensation

On May 8, 2015 (the "Effective Date"), the 2015 Long-Term Incentive Plan (the "2015 Plan") was approved by shareholders. As of the Effective Date, no additional awards will be granted to employees under the 2011 Long-Term Incentive Plan (the "2011 Plan"). The significant terms of stock options and restricted stock units ("RSUs") were not changed under the 2015 Plan. Stock options and RSUs are issued to officers and/or other management employees under these plans. Stock options generally vest over a four-year period and have an expiration of ten years from the issuance date. RSUs generally "cliff" vest after a three-year period and include units with and without performance criteria. RSUs with performance criteria provide for full "cliff" vesting after three years if the Compensation Committee certifies that the performance goals have been met. Upon vesting, the holder will receive one share of common stock of the Company for each vested restricted stock unit.

Commencing in February 2013, the Company began issuing shares from treasury stock to cover the exercised options and vested RSUs. Prior to February 2013, the Company generally issued new shares from its authorized but unissued share pool. As of December 31, 2021, approximately 10 million shares of ITW common stock were reserved for issuance under these plans.

The Company records compensation expense for the grant date fair value of stock awards over the remaining service periods of those awards. The following table summarizes the Company's stock-based compensation expense for the twelve months ended December 31, 2021, 2020 and 2019:

In millions			2021						2020						2019
Pre-tax stock-based compensation expense			$	53					$	42					$	41
Tax benefit			(6)						(5)						(5)
Total stock-based compensation expense, net of tax			$	47					$	37					$	36

The following table summarizes activity related to non-vested RSUs for the twelve months ended December 31, 2021:

Shares in millions			Number of Shares						Weighted-Average Grant-Date Fair Value
Unvested, January 1, 2021			0.5						$164.76
Granted			0.2						200.87
Vested			(0.1)						163.41
Unvested, December 31, 2021			0.6						178.60

The following table summarizes stock option activity for the twelve months ended December 31, 2021:

In millions except exercise price and contractual terms			Number of Shares						Weighted-Average Exercise Price						Weighted-Average Remaining Contractual Term						Aggregate Intrinsic Value
Under option, January 1, 2021			3.2						$128.81
Granted			0.5						200.98
Exercised			(0.5)						92.62
Canceled or expired			(0.1)						181.06
Under option, December 31, 2021			3.1						144.93						6.1						$312
Exercisable, December 31, 2021			1.9						123.58						4.9						$239

The fair value of RSUs is equal to the common stock fair market value on the date of the grant. RSUs provide for dividend equivalents payable in additional RSUs for dividends that would have been paid during the vesting period. Stock option exercise prices are equal to the common stock fair market value on the date of grant. The Company estimates forfeitures based on historical rates for awards with similar characteristics. The Company uses a binomial option pricing model to estimate the fair value of the stock options granted. The following summarizes the assumptions used in the option valuations for the twelve months ended December 31, 2021, 2020 and 2019:

			2021						2020						2019
Risk-free interest rate			0.04-1.38%						1.41-1.59%						2.50%-2.68%
Weighted-average volatility			24.0%						21.0%						22.0%
Dividend yield			2.50%						2.56%						2.20%
Expected years until exercise			8.9-9.4						9.1-9.6						8.7-9.0

Lattice-based option valuation models, such as the binomial option pricing model, incorporate ranges of assumptions for inputs. The risk-free rate of interest for periods within the contractual life of the option is based on a zero-coupon U.S. government instrument over the contractual term of the equity instrument. Expected volatility is based on implied volatility from traded options on the Company's stock and historical volatility of the Company's stock. The Company uses historical data to estimate option exercise timing and employee termination rates within the valuation model. The weighted-average dividend yield is based on historical information. The expected term of options granted is derived from the output of the option valuation model and represents the period of time that options granted are expected to be outstanding. The ranges presented result from separate groups of employees assumed to exhibit different exercise behavior.

The weighted-average grant-date fair value of stock options granted for the twelve months ended December 31, 2021, 2020 and 2019 was $40.90, $35.45 and $34.36 per share, respectively. The aggregate intrinsic value of stock options exercised during the twelve months ended December 31, 2021, 2020 and 2019 was $68 million, $114 million and $127 million, respectively. As of December 31, 2021, there was $9 million of total unrecognized compensation cost related to unvested stock options. That cost is expected to be recognized over a weighted-average period of 2 years. Exercise of stock options during the twelve months ended December 31, 2021, 2020 and 2019 resulted in cash receipts of $50 million, $66 million and $85 million, respectively. The total fair value of vested stock option awards during the twelve months ended December 31, 2021, 2020 and 2019 was $19 million, $16 million and $17 million, respectively.

As of December 31, 2021, there was $47 million of total unrecognized compensation cost related to unvested RSUs. That cost is expected to be recognized over a weighted-average remaining contractual life of 1.8 years. The total fair value of vested RSU awards during the twelve months ended December 31, 2021, 2020 and 2019 was $23 million, $25 million and $20 million, respectively.
