Notes to Financial Statements (Unaudited)

(1) Significant Accounting Policies

Financial Statements— The unaudited financial statements included herein have been prepared by Illinois Tool Works Inc. and Subsidiaries (the "Company"). In the opinion of management, the interim financial statements reflect all adjustments of a normal recurring nature necessary for a fair statement of the results for interim periods. It is suggested that these financial statements be read in conjunction with the financial statements and notes to financial statements included in the Company's 2020 Annual Report on Form 10-K. Certain reclassifications of prior year data have been made to conform with current year reporting.

(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. In the first quarter of 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. A prolonged outbreak will continue to interrupt the operations of the Company and its customers and suppliers.

(3) 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 three months ended March 31, 2021 and 2020 was as follows:


	Three Months Ended
	March 31,
In millions	2021		2020
Automotive OEM	$	783	$	696
Food Equipment	451		483
Test & Measurement and Electronics	552		485
Welding	401		372
Polymers & Fluids	435		393
Construction Products	469		390
Specialty Products	457		414
Intersegment revenue	(4)		(5)
Total operating revenue	$	3,544	$	3,228

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:

•warewashing equipment;

•cooking equipment, including ovens, ranges and broilers;

•refrigeration equipment, including refrigerators, freezers and prep tables;

•food processing equipment, including slicers, mixers and scales;

•food equipment service, maintenance and repair.

Revenue for equipment sold in this segment is typically recognized at the time of product shipment. In limited circumstances involving installation of equipment and customer acceptance, the Company may recognize revenue upon completion of installation and acceptance by the customer. Annual service contracts are typically sold separate from equipment and the related revenue is recognized on a straight-line basis over the annual service period. Operating revenue for on-demand service repairs and parts is recorded upon completion and customer acceptance of the work performed.

Test & Measurement and Electronics— This segment is a branded and innovative producer of test and measurement and electronic manufacturing and maintenance, repair, and operations, or "MRO" solutions that improve efficiency and quality for customers in diverse end markets. Businesses in this segment produce equipment, consumables, and related software for testing and measuring of materials and structures, as well as equipment and consumables used in the production of electronic subassemblies and microelectronics. This segment primarily serves the electronics, general industrial, industrial capital goods, automotive original equipment manufacturers and tiers, energy and consumer durables markets. Products in this segment include:

•electronic assembly equipment;

•electronic components and component packaging;

•static control equipment and consumables used for contamination control in clean room environments; and

•pressure sensitive adhesives and components for electronics, medical, transportation and telecommunications applications.

Revenue for products sold in this segment is typically recognized at the time of shipment. In limited circumstances where significant obligations to the customer are unfulfilled at the time of shipment, typically involving installation of equipment and customer acceptance, revenue recognition is deferred until such obligations have been completed.

Welding— This segment is a branded value-added equipment and specialty consumable manufacturer with innovative and leading technology. Businesses in this segment produce arc welding equipment, consumables and accessories for a wide array of industrial and commercial applications. This segment primarily serves the general industrial market, which includes fabrication, shipbuilding and other general industrial markets, and energy, construction, MRO, automotive original equipment manufacturers and tiers, and industrial capital goods markets. Products in this segment include:

•fasteners and related fastening tools for wood and metal applications;

•anchors, fasteners and related tools for concrete applications;

•metal plate truss components and related equipment and software; and

•packaged hardware, fasteners, anchors and other products for retail.

Products in this segment are primarily manufactured to meet anticipated customer demand. The Company typically recognizes revenue for these products at the time of product shipment.

Specialty Products— This segment is focused on diversified niche market opportunities with substantial patent protection producing beverage packaging equipment and consumables, product coding and marking equipment and consumables, and appliance components and fasteners. This segment primarily serves the food and beverage, consumer durables, general industrial, industrial capital goods and printing and publishing markets. Products in this segment include:

•line integration, conveyor systems and line automation for the food and beverage industries;

•plastic consumables that multi-pack cans and bottles and related equipment;

•foil, film and related equipment used to decorate consumer products;

•product coding and marking equipment and related consumables;

Products in this segment are primarily manufactured to meet anticipated customer demand. The Company typically recognizes revenue for these products at the time of product shipment. In limited circumstances where significant obligations to the customer are unfulfilled at the time of shipment, typically involving installation of equipment and customer acceptance, revenue is recognized when such obligations have been completed.

(4) Income Taxes

The Company's effective tax rate for the three months ended March 31, 2021 and 2020 was 22.4% and 23.0%, respectively. The effective tax rate for the three months ended March 31, 2021 and 2020 benefited from discrete income tax benefits of $9 million and $7 million, respectively, related to excess tax benefits from stock-based compensation.

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 ("IRS"), 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. Due to the ongoing audits, 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 $99 million related predominantly to various intercompany transactions. The Company has recorded its best estimate of the potential exposure for these issues.

(5) Inventories

ITEM 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

INTRODUCTION

Illinois Tool Works Inc. (the "Company" or "ITW") is a global manufacturer of a diversified range of industrial products and equipment with 83 divisions in 52 countries. As of December 31, 2020, the Company employed approximately 43,000 people.

Due to the large number of diverse businesses and the Company's decentralized operating structure, the Company does not require its businesses to provide detailed information on operating results. Instead, the Company's corporate management collects data on several key measurements: operating revenue, operating income, operating margin, overhead costs, number of months on hand in inventory, days sales outstanding in accounts receivable, past due receivables and return on invested capital. These key measures are monitored by management and significant changes in operating results versus current trends in end markets and variances from forecasts are discussed with operating unit management.

THE ITW BUSINESS MODEL

The powerful and highly differentiated ITW Business Model is the Company's core source of value creation. The ITW Business Model is the Company's competitive advantage and defines how ITW creates value for its shareholders. It is comprised of three unique elements:

•ITW's 80/20 Front-to-Back process is the operating system that is applied in every ITW business. Initially introduced as a manufacturing efficiency tool in the 1980s, ITW has continually refined, improved and expanded 80/20 into a proprietary, holistic business management process that generates significant value for the Company and its customers. Through the application of data driven insights generated by 80/20 practice, ITW focuses on its largest and best opportunities (the "80") and eliminates cost, complexity and distractions associated with the less profitable opportunities (the "20"). 80/20 enables ITW businesses to consistently achieve world-class operational excellence in product availability, quality, and innovation, while generating superior financial performance;

•Customer-Back Innovation has fueled decades of profitable growth at ITW. The Company's unique innovation approach is built on insight gathered from the 80/20 Front-to-Back process. Working from the customer back, ITW businesses position themselves as the go-to problem solver for their "80" customers. ITW's innovation efforts are focused on understanding customer needs, particularly those in "80" markets with solid long-term growth fundamentals, and creating unique solutions to address those needs. These customer insights and learnings drive innovation at ITW and have contributed to a portfolio of approximately 18,500 granted and pending patents;

•ITW's Decentralized, Entrepreneurial Culture enables ITW businesses to be fast, focused, and responsive. ITW businesses have significant flexibility within the framework of the ITW Business Model to customize their approach in order to best serve their specific customers' needs. ITW colleagues recognize their unique responsibilities to execute

the Company's strategy and values. As a result, the Company maintains a focused and simple organizational structure that, combined with outstanding execution, delivers best-in-class services and solutions adapted to each business' customers and end markets.

ENTERPRISE STRATEGY

In late 2012, ITW began its strategic framework transitioning the Company on its current path to fully leverage the compelling performance potential of the ITW Business Model. The Company undertook a complete review of its performance, focusing on its businesses delivering consistent above-market growth with best-in-class margins and returns, and developing a strategy to replicate that performance across its operations.

ITW determined that solid and consistent above-market organic growth is the core growth engine to deliver world-class financial performance and compelling long-term returns for its shareholders. To shift its primary growth engine to organic, the Company began executing a multi-step approach.

•The first step was to narrow the focus and improve the quality of ITW's business portfolio. As part of the Portfolio Management initiative, ITW exited businesses that were operating in commoditized market spaces and prioritized sustainable differentiation as a must-have requirement for all ITW businesses. This process included both divesting entire businesses and exiting commoditized product lines and customers inside otherwise highly differentiated ITW divisions.

As a result of this work, ITW's business portfolio now has significantly higher organic growth potential. ITW segments and divisions now possess attractive and differentiated product lines and end markets as they continue to improve operating margins and generate price/cost increases. The Company achieved this through product line simplification, or eliminating the complexity and overhead costs associated with smaller product lines and customers, while supporting and growing the businesses' largest / most profitable customers and product lines.

•Step two, Business Structure Simplification, was implemented to simplify and scale up ITW's operating structure to support increased engineering, marketing, and sales resources, and improve global reach and competitiveness, all of which were critical to driving accelerated organic growth. ITW now has 83 scaled-up divisions with significantly enhanced focus on growth investments, core customers and products, and customer-back innovation.

•The Strategic Sourcing initiative established sourcing as a core strategic and operational capability at ITW, delivering an average of one percent reduction in spend each year from 2013 through 2020 and continues to be a key contributor to the Company's ongoing enterprise strategy.

•With the initial portfolio realignment and scale-up work largely complete, the Company shifted its focus to preparing for and accelerating organic growth, reapplying the 80/20 Front-to-Back process to optimize its newly scaled-up divisions for growth, first, to build a foundation of operational excellence, and second, to identify the best opportunities to drive organic growth.

ITW has clearly demonstrated superior 80/20 management, resulting in meaningful incremental improvement in margins and returns as evidenced by the Company's operating margin and after-tax return on invested capital. At the same time, these 80/20 initiatives can also result in restructuring initiatives that reduce costs and improve profitability and returns.

PATH TO FULL POTENTIAL

Since the launch of the enterprise strategy, the Company has made considerable progress to position itself to reach full potential. The ITW Business Model and unique set of capabilities are a source of strong and enduring competitive advantage, but for the Company to truly reach its full potential, every one of its divisions must also be operating at its full potential. To do so, the Company remains focused on its core principles to position ITW to perform to its full potential:

•Portfolio discipline

•80/20 Front-to-Back practice excellence

•Full-potential organic growth

Portfolio Discipline

The Company only operates in industries where it can generate significant, long-term competitive advantage from the ITW Business Model. ITW businesses have the right "raw material" in terms of market and business attributes that best fit the ITW Business Model and have significant potential to drive above-market organic growth over the long-term.

The Company focuses on high-quality businesses, ensuring it operates in markets with positive long-term macro fundamentals and with customers that have critical needs and value ITW's differentiated products, services and solutions. ITW's portfolio operates in highly diverse end markets and geographies which makes the Company more resilient in the face of uncertain or volatile market environments.

The Company routinely evaluates its portfolio to ensure it delivers sustainable differentiation and drives consistent long-term performance. This includes both implementing portfolio refinements and assessing selective high-quality acquisitions to supplement ITW's long-term growth potential.

The Company previously communicated its intent to explore options, including potential divestitures, for certain businesses with revenues totaling up to $1 billion. The Company expects any earnings per share dilution from divestitures would be offset by incremental share repurchases. In the fourth quarter of 2019, the Company completed the divestitures of three businesses and continues to evaluate options for certain other businesses. However, due to the COVID-19 pandemic, the Company has deferred any further significant divestiture activity until market conditions normalize.

80/20 Front-to-Back Practice Excellence

The 80/20 Front-to-Back process is a rigorous, iterative and highly data-driven approach to identify where the Company has true differentiation and the ability to drive sustainable, high-quality organic growth. The Company simplifies and eliminates complexity and redesigns every aspect of its business to ensure focused execution on key opportunities, markets, customers, and products.

ITW will continue to drive 80/20 Front-to-Back practice excellence in every division in the Company, every day. Driving strong operational excellence in the quality of 80/20 Front-to-Back practice across the Company, division by division, will produce further customer-facing performance improvement in a number of the Company's divisions and additional structural margin expansion at the enterprise level.

Near-term Priorities

While it was the challenges brought about by the COVID-19 pandemic that dominated the Company's attention starting in 2020, it was the collection of capabilities and competitive advantages that have been built and honed over the past eight years through the execution of ITW's enterprise strategy that provided the Company with the options to respond. This, coupled with the proprietary and powerful ITW Business Model, diversified high-quality business portfolio and diligent execution put the Company in a position of strength in dealing with the global pandemic.

From the early days of the pandemic, the Company focused its efforts on the following priorities: (1) protect the health and support the well-being of ITW's colleagues; (2) continue to serve the Company's customers with excellence to the best of its ability; (3) maintain financial strength, liquidity and strategic optionality; and (4) leverage the Company's strengths to position it to fully participate in the recovery.

"Win the Recovery" is an execution component of the Company's enterprise strategy, not a separate initiative, with every one of the Company's divisions identifying specific opportunities presented by the pandemic to capture sustainable share gains that are aligned with the ITW long-term enterprise strategy. The Company expects these efforts to contribute meaningfully to accelerate its progress toward full-potential organic growth. The Company continues to focus on delivering strong results in any environment while executing its long-term strategy to achieve and sustain ITW's full potential performance.

Full-Potential Organic Growth

Reaching full potential means that every division is positioned for sustainable, high-quality organic growth. The Company has clearly defined action plans aimed at leveraging the performance power of the ITW Business Model to achieve full-potential organic growth in every division, with specific focus on:

•"80" focused Market Penetration - fully leveraging the considerable growth potential that resides in the Company's largest and most differentiated product offerings and customer relationships

•Customer-back Innovation - strengthening the Company's commitment to serial innovation and delivering a continuous flow of differentiated new products to its key customers

•Strategic Sales Excellence - deploying a high-performance sales function in every division

As the Company continues to make progress toward its full potential, the Company will explore opportunities to reinforce or further expand the long-term organic growth potential of ITW through the addition of selective high-quality acquisitions, such as the recently announced agreement with Amphenol Corporation ("Amphenol"), whereby the Company intends to acquire the Test & Simulation business of MTS Systems Corporation ("MTS") from Amphenol, which is expected to close following the receipt of all required regulatory approvals and the satisfaction of other customary closing conditions. Upon completion of this acquisition, the Test & Simulation business of MTS will be reported within the Company's Test & Measurement and Electronics segment.

TERMS USED BY ITW

Management uses the following terms to describe the financial results of operations of the Company:

•Organic business - acquired businesses that have been included in the Company's results of operations for more than 12 months on a constant currency basis.

•Operating leverage - the estimated effect of the organic revenue volume changes on organic operating income, assuming variable margins remain the same as the prior period.

•Price/cost - represents the estimated net impact of increases or decreases in the cost of materials used in the Company's products versus changes in the selling price to the Company's customers.

•Product line simplification (PLS) - focuses businesses on eliminating the complexity and overhead costs associated with smaller product lines and customers, and focuses businesses on supporting and growing their largest customers and product lines. In the short-term, PLS may result in a decrease in revenue and overhead costs while improving operating margin. In the long-term, PLS is expected to result in growth in revenue, profitability, and returns.

Unless otherwise stated, the changes in financial results in the consolidated results of operations and the results of operations by segment represent the current year period versus the comparable period in the prior year. The following discussion of operating results should be read in conjunction with Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations in the Company's 2020 Annual Report on Form 10-K.

CONSOLIDATED RESULTS OF OPERATIONS

For the duration of the COVID-19 pandemic, the Company is focusing on the following priorities: (1) protect the health and support the well-being of ITW's colleagues; (2) continue to serve the Company's customers with excellence to the best of its ability; (3) maintain financial strength, liquidity and strategic optionality; and (4) leverage the Company's strengths to position it to fully participate in the recovery phase. To support ITW's colleagues, among its many actions and initiatives, the Company redesigned production processes to ensure proper social distancing practices, adjusted shift schedules and assignments to help colleagues who have child and elder care needs, and implemented aggressive new workplace sanitation practices and a coordinated response to ensure access to personal protective equipment to minimize infection risk. To support its customers, the Company has worked diligently to keep its facilities open and operating safely. The Company has adapted customer service systems and practices to seamlessly serve its customers under "work from home" requirements in many parts of the world.

In areas around the world where governments issued stay-at-home or similar orders, the vast majority of ITW's businesses were designated as critical or essential businesses and, as such, they remained open and operational. In some cases, this is because the Company's products directly impact the COVID-19 response effort. In other cases, the Company's businesses are designated as critical because they play a vital role in serving and supporting industries that are deemed essential to the physical and economic health of our communities.

While the vast majority of the Company's facilities have remained open and operational during the pandemic, many of these facilities were operating at a reduced capacity. The full extent of the COVID-19 outbreak and its impact on the markets served by the Company and on the Company's operations and financial position continues to be highly uncertain. A prolonged outbreak will continue to interrupt the operations of the Company and its customers and suppliers. A description of the risks relating to the impact of the COVID-19 outbreak on the Company's business, operations and financial condition is contained in Part I - Item 1A - Risk Factors in the Company's 2020 Annual Report on Form 10-K.

Separately, the Company does not believe that tariffs imposed in recent years have had a material impact on its operating results. The Company will continue to evaluate the impact of enacted and proposed tariffs on its businesses, as well as pricing actions to mitigate the impact of any raw material cost increases resulting from these tariffs.

The Company delivered strong financial results in the first quarter of 2021, as the Company experienced solid recovery progress in many of its end markets. The primary drivers of the Company's financial performance are the continued successful execution of enterprise initiatives, including the "Win the Recovery" actions initiated over the course of the past year, and continued focus on the highly differentiated ITW Business Model. Despite rising raw material costs and a challenging global supply chain environment, the Company generated operating revenue growth of 9.8 percent, operating income growth of 18.8 percent, operating margin was 25.5 percent and after-tax return on average invested capital was 32.1 percent. Additionally, with the exception of the Food Equipment segment, all segments achieved organic revenue growth, and all seven segments had operating margins that exceeded 21 percent.

◦North American organic revenue grew 11.8% as the United States residential and commercial end markets increased 12.8% and 2.8%, respectively.

◦International organic revenue increased 13.7%. European organic revenue increased 18.9% primarily driven by an increase in continental Europe and the United Kingdom in the commercial and residential end markets. Asia Pacific organic revenue increased 6.9% primarily due to an increase in Australia and New Zealand in the retail and residential end markets.

•Operating margin of 27.6% in the first quarter increased 420 basis points primarily driven by positive operating leverage of 260 basis points and net benefits from the Company's enterprise initiatives and cost management.

•Operating revenue increased due to higher organic revenue and the favorable effect of foreign currency translation.

•Organic revenue increased 7.3%. Consumable sales grew 7.3% primarily due to higher demand in North America and Asia Pacific. Equipment sales increased 7.6% as higher demand in Europe and North America was offset by lower demand in Asia Pacific.

◦North American organic revenue increased 5.7% as growth in the consumer packaging businesses was partially offset by a decline in the ground support equipment businesses.

◦International organic revenue increased 9.9% primarily due to an increase in the appliances businesses in Europe and Asia Pacific and the ground support equipment businesses in Europe.

•Operating margin of 27.6% in the first quarter increased 130 basis points primarily driven by positive operating leverage of 140 basis points and net benefits from the Company's enterprise initiatives and cost management, partially offset by unfavorable price/cost of 150 basis points and higher restructuring expenses.

OTHER FINANCIAL HIGHLIGHTS

•Interest expense in the first quarter of 2021 was $52 million versus $51 million in the first quarter of 2020.

•Other income (expense) was income of $12 million in the first quarter of 2021, a decrease of $13 million compared to the first quarter of 2020 primarily due to lower foreign currency translation gains and lower interest income in 2021.

LIQUIDITY AND CAPITAL RESOURCES

The Company's primary sources of liquidity are free cash flow and short-term credit facilities. As of March 31, 2021, the Company had $2.5 billion of cash and equivalents on hand, no outstanding borrowings under its $2.5 billion revolving credit facility, and no commercial paper outstanding. The Company also has maintained strong access to public debt markets. Management believes that these sources are sufficient to service debt and to finance the Company's capital allocation priorities, which include:

•internal investments to support organic growth and sustain core businesses;

•payment of an attractive dividend to shareholders; and

•external investments in selective strategic acquisitions that support the Company's organic growth focus, and an active share repurchase program.

The Company believes that, based on its operating revenue, operating margin, free cash flow, and credit ratings, it could readily obtain additional financing, if necessary. A description of the risks related to the impact of the COVID-19 outbreak on the financial and capital markets and the related potential risks to the Company is contained in Part I - Item 1A - Risk Factors in the Company's 2020 Annual Report on Form 10-K.

Cash Flow

The Company uses free cash flow to measure cash flow generated by operations that is available for dividends, share repurchases, acquisitions and debt repayment. The Company believes this non-GAAP financial measure is useful to investors in evaluating the Company's financial performance and measures the Company's ability to generate cash internally to fund Company initiatives. Free cash flow represents net cash provided by operating activities less additions to plant and equipment. Free cash flow is a measurement that is not the same as net cash flow from operating activities per the statement of cash flows and may not be consistent with similarly titled measures used by other companies. Summarized cash flow information for the first quarter of 2021 and 2020 was as follows:


	Three Months Ended

Net increase (decrease) in cash and equivalents	$	(80)	$	(551)

Stock Repurchase Program

On August 3, 2018, the Company's Board of Directors authorized a stock repurchase program which provides for the repurchase of up to $3.0 billion of the Company's common stock over an open-ended period of time (the "2018 Program"). Under the 2018 Program, the Company repurchased approximately 2.0 million shares of its common stock at an average price of $149.04 in the second quarter of 2019, approximately 2.4 million shares of its common stock at an average price of $150.97 in the third quarter of 2019, approximately 2.2 million shares of its common stock at an average price of $175.02 in the fourth quarter of 2019, and approximately 4.2 million shares of its common stock at an average price of $167.69 in the first quarter of 2020. Due to the COVID-19 pandemic, the Company temporarily suspended its share repurchase program starting in March 2020. In February 2021, the Company resumed its share repurchase program and repurchased approximately 1.2 million shares of its common stock at an average price of $211.50 in the first quarter of 2021. As of March 31, 2021, there were $990 million of authorized repurchases remaining under the 2018 Program.

After-tax Return on Average Invested Capital

The Company uses after-tax return on average invested capital ("After-tax ROIC") to measure the effectiveness of its operations' use of invested capital to generate profits. After-tax ROIC is a non-GAAP financial measure that the Company believes is a meaningful metric to investors in evaluating the Company's financial performance and may be different than the method used by other companies to calculate After-tax ROIC. Average invested capital represents the net assets of the Company, excluding cash and equivalents and outstanding debt, which are excluded as they do not represent capital investment in the Company's operations. Average invested capital is calculated using balances at the start of the period and at the end of each quarter. After-tax ROIC for the first quarter of 2021 and 2020 was as follows:


	Three Months Ended
	March 31,
Dollars in millions	2021			2020
Operating income	$	905		$	761
Tax rate	22.4		%	23.0		%

Operating income after taxes	$	702		$	586

Invested capital:

Inventories	1,292			1,185
Net assets held for sale	—			181
Net plant and equipment	1,746			1,704
Goodwill and intangible assets	5,379			5,237
Accounts payable and accrued expenses	(1,850)			(1,593)

Average invested capital	$	8,740		$	8,677
After-tax return on average invested capital	32.1		%	27.0		%

After-tax ROIC increased 510 basis points for the three month period ended March 31, 2021 compared to the prior year period as a result of a 19.7% increase in after-tax operating income versus a 0.7% increase in average invested capital.

Working Capital

Management uses working capital as a measurement of the short-term liquidity of the Company. Net working capital as of March 31, 2021 and December 31, 2020 is summarized as follows:


In millions	March 31, 2021		December 31, 2020		Increase/ (Decrease)
Current assets:
Cash and equivalents	$	2,484	$	2,564	$	(80)
Trade receivables	2,662		2,506		156
Inventories	1,292		1,189		103

Accounts payable and accrued expenses	1,850		1,818		32
Other	480		421		59
Total current liabilities	2,680		2,589		91
Net working capital	$	4,024	$	3,934	$	90

As of March 31, 2021, a significant portion of the Company's cash and equivalents was held by international subsidiaries. Cash and equivalents held internationally may be subject to foreign withholding taxes if repatriated to the U.S. Cash and equivalents held internationally are typically used for international operating needs or reinvested to fund expansion of existing international businesses. International funds may also be used to fund international acquisitions or, if not considered permanently invested, may be repatriated to the U.S. The Company has accrued for foreign withholding taxes related to foreign held cash and equivalents that are not permanently invested.

In the U.S., the Company utilizes cash flows from operations to fund domestic cash needs and the Company's capital allocation priorities. This includes operating needs of the U.S. businesses, dividend payments, share repurchases, acquisitions, servicing of domestic debt obligations, reinvesting to fund expansion of existing U.S. businesses and general corporate needs. The Company may also use its commercial paper program, which is backed by long-term credit facilities, for short-term liquidity needs. The Company believes cash generated by operations and liquidity provided by the Company's commercial paper program will continue to be sufficient to fund cash requirements in the U.S.

Debt

Total debt as of March 31, 2021 and December 31, 2020 was as follows:


In millions	March 31, 2021		December 31, 2020
Short-term debt	$	350	$	350
Long-term debt	7,599		7,772
Total debt	$	7,949	$	8,122

There was no commercial paper outstanding as of March 31, 2021 and December 31, 2020. Short-term debt as of March 31, 2021 and December 31, 2020 included $350 million related to the 3.375% notes due September 15, 2021. The Company has a $2.5 billion revolving credit facility with a termination date of September 27, 2024, which is available to provide additional liquidity, including to support the potential issuances of commercial paper. No amounts were outstanding under the $2.5 billion revolving credit facility as of March 31, 2021 or December 31, 2020.

Total Debt to EBITDA

The Company uses the ratio of total debt to EBITDA as a measure of its ability to repay its outstanding debt obligations. EBITDA and the ratio of total debt to EBITDA are non-GAAP financial measures. The Company believes that total debt to EBITDA is a meaningful metric to investors in evaluating the Company's long term financial liquidity and may be different

than the method used by other companies to calculate total debt to EBITDA. The ratio of total debt to EBITDA represents total debt divided by net income before interest expense, other income (expense), income taxes, depreciation, and amortization and impairment of intangible assets on a trailing twelve month basis. Total debt to EBITDA for the trailing twelve month periods ended March 31, 2021 and December 31, 2020 was as follows:


Dollars in millions	March 31, 2021		December 31, 2020
Total debt	$	7,949	$	8,122

Net income	$	2,214	$	2,109

Novel Coronavirus (COVID-19)	Mar. 31, 2021
Unusual or Infrequent Items, or Both [Abstract]
Novel Coronavirus (COVID-19)	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. In the first quarter of 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. A prolonged outbreak will continue to interrupt the operations of the Company and its customers and suppliers.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective tax rate for the three months ended March 31, 2021 and 2020 was 22.4% and 23.0%, respectively. The effective tax rate for the three months ended March 31, 2021 and 2020 benefited from discrete income tax benefits of $9 million and $7 million, respectively, related to excess tax benefits from stock-based compensation. 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 ("IRS"), 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. Due to the ongoing audits, 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 $99 million related predominantly to various intercompany transactions. The Company has recorded its best estimate of the potential exposure for these issues.
