Illinois Tool Works Inc. and Subsidiaries
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 20162017 Annual Report on Form 10-K. Certain reclassifications of prior year data have been made to conform with current year reporting.

Operating Revenue— Prior to 2018, the Company recognized revenue when persuasive evidence of an arrangement existed, product had shipped and the risks and rewards of ownership had transferred or services had been rendered, the price to the customer was fixed or determinable, and collectibility was reasonably assured, which generally occurred at the time of product shipment. Effective January 1, 2018, the Company adopted new revenue recognition guidance. Under this new guidance, 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, arrangements may include service performed over time, or 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 recognized over time as the service is provided to the customer or deferred until all significant obligations have been completed. 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 was $254 million and $205 million as of March 31, 2018 and December 31, 2017, respectively, and is short-term in nature. For additional information regarding the Company's operating revenue, see New Accounting Pronouncements - below and Note 2. Operating Revenue.

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (the "FASB"“FASB”) issued authoritative guidance to change the criteria for revenue recognition. The core principle of the new standardguidance is that revenue should be recognized to depict the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, several newexpanded revenue recognition disclosures will beare required. Under current guidance, the CompanyThe Company's sales arrangements with customers are predominantly short-term in nature and generally recognizes operating revenue whenprovide for transfer of control and risks and rewards of ownership and risk of loss are transferred to the customer, which is typically at the time of product shipment or delivery of service. The Company has completed a reviewAs such, the timing of revenue transactionsrecognition under both the prior and new guidance is the same for a significant portionthe majority of its businesses. While the review is not fully completed,Company’s transactions. Effective January 1, 2018, the Company doesadopted the new revenue guidance under the modified retrospective method and recorded a cumulative-effect adjustment reducing retained earnings by $9 million as of January 1, 2018. Under the modified retrospective method of adoption, prior periods are not currently expectrestated and the adoptionnew guidance is applied prospectively to revenue transactions completed on or after January 1, 2018. Given the nature of thisthe Company’s revenue transactions, the new guidance to have a materialhad an immaterial impact on itsthe Company's operating revenue, results of operations, and financial position for the three months ended March 31, 2018. The Company updated its revenue recognition accounting policy to reflect the requirements of the new guidance and included additional disclosures regarding the Company's revenue transactions. Refer to the Company’s operating revenue accounting policy above and Note 2. Operating Revenue for additional information.

In October 2016, the FASB issued authoritative guidance requiring the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs rather than when transferred to a third party as required under the prior guidance. The provisions of the new guidance will be applied prospectively to intra-entity asset transfers on or financial position. However,after January 1, 2018 and may result in future tax rate volatility. Upon adoption of the new guidance on January 1, 2018, the Company expectsrecorded a cumulative-effect adjustment reducing deferred tax assets and retained earnings by $406 million. For the three months ended March 31, 2018, the impact of the new guidance on the Company's effective income tax rate was not material.


In March 2017, the FASB issued authoritative guidance which changes the income statement presentation of net periodic benefit cost related to provide additionaldefined benefit pension and other postretirement plans. The primary change under the new guidance is that only the service cost component of net periodic benefit cost should be included in operating income and is eligible for capitalization as an asset. The other components of net periodic benefit cost ("other net periodic benefit cost"), including interest cost, expected return on assets, settlements, curtailments, and amortization of actuarial gains and losses and prior service cost, should be presented below operating income. Effective January 1, 2018, the Company adopted the new presentation of other net periodic benefit cost and restated the prior year statement of income and related disclosures in the notes to financial statementsfor comparability, as required under the new guidance. For the three months ended March 31, 2018 and 2017, other net periodic benefit cost was income of $5 million and $2 million, respectively, and was presented in Other income (expense) in both periods. Refer to Note 5. Pension and Other Postretirement Benefits for additional information.

In February 2018, the FASB issued authoritative guidance which allows for an optional one-time reclassification of the stranded tax effects resulting from the change in the U.S. federal corporate income tax rate under the "Tax Cuts and Jobs Act" (the "Act") from accumulated other comprehensive income ("AOCI") to retained earnings. The new guidance will beis effective for theJanuary 1, 2019, with early adoption permitted. The Company beginningelected to early adopt this guidance as of January 1, 2018 and allowsto reclassify the stranded tax effects related to the Act, which resulted in an increase of $45 million to both retained earnings and accumulated other comprehensive loss. Refer to Note 7. Accumulated Other Comprehensive Income (Loss) for either full or modified retrospective adoption methods. The Company expects to adopt the new revenue accounting guidance utilizing the modified retrospective method.additional information.

In February 2016, the FASB issued authoritative guidance to change the criteria for recognizing leasing transactions. Under the new guidance, a lessee will be required to recognize a lease liability and right-of-use lease asset for all leases with a lease term greater than twelve months, including operating leases, in the statement of financial position, including operating leases.position. Subsequent measurement, including presentation of expenses and cash flows, will depend on the classification of the lease as either a financing or operating lease. In addition, several newexpanded disclosures will be required. This guidance will beis effective for the Company beginning January 1, 2019, with early adoption permitted. While the Company has not yet completed its evaluation of the impact the new lease accounting guidance will have on the consolidated financial statements and related disclosures, the Company expects to recognize right of useright-of-use assets and liabilities for its operating leases in the statement of financial position upon adoption.

In March 2016, the FASB issued authoritative guidance that included several changes to simplify the accounting for stock-based compensation, including the accounting for income taxes, forfeitures, statutory tax withholding requirements and classification of tax benefits in the statement of cash flows. Among the more significant changes, the new guidance requires the income tax effects associated with the settlement of stock-based awards to be recognized through income tax expense rather than directly in equity. Additionally, the income tax effects related to excess tax benefits should be presented within operating cash flows in the statement of cash flows rather than as a financing activity. Excess tax benefits recognized in equity under the prior guidance were $25 million for the nine months ended September 30, 2016. The Company adopted the new guidance effective January 1, 2017 and applied the newly adopted provisions prospectively. Excess tax benefits of $6 million and $32 million were included in Income Taxes in the statement of income for the three and nine month periods ended September 30, 2017, respectively. The expected effect on income tax expense or net cash provided from operating activities related to future stock-based award settlements will vary each quarter and will depend on inputs such as the stock price at the time of settlement and the number of awards settled in the period presented.

In October 2016, the FASB issued authoritative guidance requiring the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs rather than when transferred to a third party as required under the current guidance. The new guidance is effective for the Company beginning January 1, 2018 and will be applied prospectively with the cumulative effect of adoption recorded directly to retained earnings. Although the Company is currently completing its assessment of the potential impact of this new guidance, the Company anticipates a cumulative-effect balance sheet adjustment reducing deferred tax assets and retained earnings upon adoption. Additionally, intra-entity asset transfers may result in future tax rate volatility under the new guidance. The Company intends to complete its assessment in the fourth quarter of 2017.

In March 2017, the FASB issued authoritative guidance which changes the income statement presentation of the components of net periodic benefit cost related to defined benefit pension and other postretirement plans. The primary change under the new guidance is that only the service cost component of net periodic benefit cost should be included in operating income and is


eligible for capitalization as an asset. The other components of net periodic benefit cost, such as interest cost, the expected return on assets, and amortization of actuarial gains and losses and prior service cost, should be presented below operating income. The guidance is effective for the Company starting January 1, 2018 and will be applied retrospectively to the presentation of net periodic benefit cost and prospectively to the capitalization of service cost. The Company does not expect the adoption of this guidance to have a material impact on the results of operations or financial position. Refer to Note 6. Pension and Other Postretirement Benefits for further information information regarding the Company’s net periodic benefit cost.

(2)    AcquisitionOperating Revenue

On July 1, 2016,The Company's 85 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, 2018 and 2017 was as follows:

Prior to 2018, the Company completedrecognized revenue when persuasive evidence of an arrangement existed, product had shipped and the acquisitionrisks and rewards of ownership had transferred or services had been rendered, the price to the customer was fixed or determinable, and collectibility was reasonably assured, which generally occurred at the time of product shipment. Effective January 1, 2018, the Company adopted new revenue recognition guidance. Under this new guidance, 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. Given the nature of the Engineered Fasteners and Components business ("EF&C") from ZF TRW for a purchase price of approximately $450 million. The acquisition of EF&C did not materially affectCompany’s revenue transactions, the Company’snew guidance had an immaterial impact on the Company's operating revenue, results of operations, orand financial position for the periods presented.three months ended March 31, 2018. See Note 1. Significant Accounting Policies for additional information. The following is a description of the product offerings, end markets and typical revenue transactions for each of the Company's seven segments:

EF&C hadAutomotive 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 institutional/restaurant and food retail 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;
kitchen exhaust, ventilation and pollution control systems; and
food equipment service, maintenance and repair.

Revenue for equipment sold in this segment is typically recognized at the time of $382 million for the nine months ended September 30, 2017 which was reported within the Company’s Automotive OEM segment. As a resultproduct shipment. In limited circumstances involving installation of the EF&C transaction,equipment and customer acceptance, the Company recorded $187 millionmay recognize revenue upon completion of goodwillinstallation and $134 million of amortizable intangible assets primarilyacceptance by the customer. Annual service contracts are typically sold separate from equipment and the related to customer relationships and technology. The intangible assets will be amortizedrevenue is recognized on a straight-line basis over their estimated useful lives ranging from 4the annual service period.

(3)    Income Taxes

The Company's effective tax rate for the three months ended March 31, 2018 and 2017 was 23.2% and 28.3%, respectively. The first quarter 2018 effective tax rate was lower primarily as a result of the lower U.S. corporate federal tax rate and a discrete income tax benefit of $14 million related to foreign tax credits. Additionally, the effective tax rate for both respective periods included discrete income tax benefits of $6 million and $12 million in 2018 and 2017, respectively, related to excess tax benefits from stock-based compensation.

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. At December 31, 2017, the Company had not completed the accounting for the tax effects of enactment of the Act; however, the Company made a reasonable estimate of the effects on the existing deferred tax balances and one-time transition tax. The Company continues to analyze certain aspects of the Act and may refine its calculations, which could potentially affect the measurement of the amounts recorded at December 31, 2017. The provisional amounts recorded for the year ended December 31, 2017, and unchanged at March 31, 2018, reflect the Company’s best estimate based on information currently available and are subject to future changes due to subsequent clarification of the tax law and refinement of estimated amounts.

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 $96$33 million related predominantly to various intercompany transactions. The Company has recorded its best estimate of the potential exposure for these issues.

On February 18, 2014, the Company received a Notice of Deficiency (“NOD”) from the IRS asserting that a non-taxable return of capital received from a subsidiary was a taxable dividend distribution. The NOD assesses additional taxes of $70 million for the 2006 tax year, plus interest and penalties. In May 2014, the Company petitioned the United States Tax Court to challenge the NOD. The Company's petition was subsequently denied and the case proceeded to court with the trial taking place in the third quarter of 2016. Final decision by the tax court is expected in 2017 or 2018. Although the court's final decision cannot be predicted with certainty, the Company believes its position continues to be supportable. Accordingly, no reserve has been recorded related to this matter.

(6)(5)    Pension and Other Postretirement Benefits

Beginning in 2017, the Company changed the method used to estimate the service and interest cost components of net periodic benefit cost related to pension and other postretirement benefit plans. The new method provides a more precise measure of 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. The Company accounted for this change as a change in estimate prospectively. The change did not have a material impact on the 2017 net periodic pension and other postretirement benefit costs.

Pension and other postretirement benefit costs for the three and nine months ended September 30, 2017March 31, 2018 and 20162017 were as follows:

Management's Discussion and Analysis of Financial Condition and Results of Operations for information regarding operating revenue and operating income for the Company's segments.



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 85 divisions in 5755 countries. As of December 31, 2016,2017, the Company employed approximately 50,000 persons.people.

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.

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. This business model is the Company’s competitive advantage and defines how ITW creates value for its shareholders and comprises three unique elements:

ITW’s 80/20 managementfront 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 managementfront 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 subsequently creating unique solutions to address those needs. These customer insights and learnings drive innovation at ITW and have contributed to a portfolio of more than 17,000 granted and pending patents;

ITW’s decentralized, entrepreneurial culture allowsenables 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 adapted to each business' customers and end markets.

ENTERPRISE STRATEGY

In late 2012, ITW began the processfirst phase of its strategic framework, transitioning the Company ontoon its current strategic path to fully leverage the compelling performance potential of the ITW Business Model. Since then, ITW has made considerable progress, as evidenced by the Company’s strong financial performance over the past fourfive years.

The roots of ITW’s Enterprise Strategy began in late 2011 / early 2012, when 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, ITW developed a strategy to replicate that performance across its operations.



Based on this rigorous evaluation, ITW determined that solid and consistent above-market organic growth must be 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. With the initiative nearly complete and ITW businesses demonstrating notably improved financial performance, the Company believes that the significant product line simplification work is essentially finalized and will returnreturning to more normalized levels in 2017 and beyond.levels.

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, at the same time, improve global reach and competitiveness, all of which were critical to driving accelerated organic growth. ITW now has 85 scaled-up divisions with significantly enhanced focus on growth investments, core customers and products, and customer-back innovation.

The Strategic Sourcing initiative was established sourcing as a core capability to better leverage ITW’s scale and improve global competitiveness. Sourcing is now a core strategic and operational capability at ITW. The Company’s 80/20-enabled sourcing organization has delivered an average of one percent reduction in spend each year from 2013 through 20162017 and is on track to do the same in 2017 and 2018.

With the portfolio realignment and scale-up work largely complete, the Company was able to shiftshifted its focus to preparing for and accelerating, organic growth. As a preparatory step, ITW is in the process of, reapplying 80/20 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.

Once the business has achieved operational excellence and identified the right growth opportunities, the final step is to accelerate organic growth. The process of preparing for accelerated organic growth generally takes 18 to 24 months.

Based on the financial performance of the divisions that are further along in this process, the Company believes that its organic growth framework is capable of delivering above-market organic growth across all segments. Divisions are at various phases in preparation for growth and many are either ready to grow or already growing above their respective markets. ITW management is fully aligned with this plan and very focused on executing it. As of December 31, 2016, approximately 85 percent of the divisions were ready to grow.

PATH TO FULL POTENTIAL

While the Company has made considerable progress and ITW’s performance is nearing best-in-class levels, the Company has significant opportunity for further improvement before it achieves full operating potential. In order to do so, ITW is focused on two key areas of opportunity, including: additional structural margin improvement and sustained above-market organic growth with strong incremental profitability.

Additional Structural Margin Improvement

To deliver on the additional structural margin improvement, the Company is implementing the following two levers: (1) further leveraging the 80/20 management process and (2) strategic sourcing.

The first lever, better leveraging the full power of the ITW Business Model, will be accomplished through a much more consistent and focused approach to 80/20 best practice implementation across the Company. The 80/20 management system has continuously been refined, improved and expanded into a unique holistic business management process of interconnected tools, which improves all aspects of the business and, when applied


consistently and executed more effectively, will lead to additional margin improvement. 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. TheseAt the same time, these 80/20 initiatives can also result in restructuring initiatives that reduce costs and improve profitability and returns. With this first phase of the strategy nearing completion, the Company will look ahead to the next five years and delivering differentiated performance on a sustained basis.

SUSTAINED DIFFERENTIATED PERFORMANCE

While the Company has made considerable progress and ITW’s performance is nearing best-in-class levels, the Company has significant opportunity for further improvement. The second phase of the strategic framework is focused on delivering differentiated performance on a sustained basis, with consistent above market organic growth. Moving forward, the Company remains committed to the four strategic principles that have served as the foundation of its progress over the past five years and that the Company believes best positions ITW to deliver continued differentiated performance over the next five years:

The second lever, strategic sourcing,ITW Business Model is the Company's competitive advantage
Focus on quality growth
"Do what we say" execution is a core elementcritical differentiator
Invest only where ITW has a competitive advantage

The ITW Business Model is the Company's Competitive Advantage

The ITW Business Model is the combination of a set of strategic, operational, and cultural approaches and practices that is applied to every ITW business. The Business Model has existed inside the Company for over 30 years and is truly ITW's differentiating competitive advantage. The ITW Business Model is comprised of three elements:

80/20 Front to Back Process = How the Company Operates
Customer-Back Innovation Approach = How the Company Innovates
Decentralized Entrepreneurial Culture = How the Company Executes


Focus on Quality Growth

ITW prioritizes high-quality revenue growth and, as such, the Company’s primary growth focus is organic.

Leveraging the Business Model and the 80/20 front to back process provides a clear view of where to focus for high- quality growth. The Company targets differentiated end-markets and customers with critical needs and challenging pain points. ITW generates high-quality growth through consistent customer-back innovation and customer service excellence.

The Company only invests and operates in industries and businesses that have the right “raw material” to generate high quality organic growth through the application of the ITW Business Model. ITW’s ongoing operational strategycurrent portfolio of seven segments offers solid growth potential and a sustainable enterprise-wide capability. Through the continued executionhigh degree of this initiative, the Company expects to deliver additional margin improvement with the goaldiversification in terms of a one percent reduction in spend in 2017geographic and 2018.

Sustained Above-Market Organic Growth with Strong Incremental Profitability

ITW has done extensive work on its portfolio and operating structure to positionend market exposures, enabling the Company to deliver sustainable above-market organic growth.consistent high-quality growth in an increasingly volatile and competitive global market environment.

"Do What We Say" Execution is a Critical Differentiator

ITW’s commitment to execution is a key differentiator for ITW. Living up to the Company’s commitments - “do what we say” execution - is a deeply embedded core element of the culture. The culture is the engine that translates ITW's strategy into action, and action into results.

All divisions function within a “framework” that defines how the culture operates and defines the Company’s values, business model and strategy to ensure all divisions are working toward our common set of goals. Business leaders have the flexibility to define the actions and customize their approach to meet those goals. This “flexibility within the framework” establishes an entrepreneurial environment where decisions are made “bottom up” by those with the greatest knowledge, capability and proximity to the customer, which enables our businesses to be nimble and react quickly to market conditions and customer requirements.

ITW is simple, straightforward and transparent in everything it does. The Company has narrowedsets clear performance expectations and financial targets, executes against these at the focusappropriate pace, and significantly improvedestablishes the growth potential of ITW’s business portfolio.

Invest Only Where ITW Has a Competitive Advantage

The Company is well positioned for accelerated growthhighly focused and disciplined in 2017its approach to invest only where it can leverage the ITW Business Model into compelling and beyond. To deliver on this accelerated growth, the divisions have been implementing the organic growth framework, which includes continued investment in customer-back innovation and a strengthened focus on market penetration. ITW continuessustainable competitive advantage.

ITW has made strong progress on the Company’s pivot tosupport organic growth and is well positioned to deliver on sustained above-market organic growth over the long-term.sustain its highly differentiated core businesses, such as new product innovation, marketing programs, simplification projects, and capital investments, are ITW’s number one investment priority.

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 20162017 Annual Report on Form 10-K.


CONSOLIDATED RESULTS OF OPERATIONS

The Company's strong thirdfirst quarter and year-to-date financial performance reflected continued progressfocus on leveraging the powerfulbusiness portfolio and the highly differentiated ITW Business Model and executing enterprise initiatives. Six of sevento its full potential. All segments achieved worldwide organic revenue growth in the third quarter, and all seven segments had organic revenue growth in the year-to-date period. All seven segments had operating margin at or above 21% in both respective periods.

On July 1, 2016, the Company completed the acquisition of the Engineered Fasteners and Components business ("EF&C") from ZF TRW for a purchase price of approximately $450 million.

The core principle of the new standardguidance is that revenue should be recognized to depict the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, several newexpanded revenue recognition disclosures will beare required. Under current guidance, the CompanyThe Company's sales arrangements with customers are predominantly short-term in nature and generally recognizes operating revenue whenprovide for transfer of control and risks and rewards of ownership and risk of loss are transferred to the customer, which is typically at the time of product shipment or delivery of service.

Significant Accounting Policies and lease assetNote 2. Operating Revenue in Item 1.

While the Company has not yet completed its evaluation of the impact the new lease accounting guidance will have on the consolidated financial statements and related disclosures, the Company expects to recognize right of use assets and liabilities for its operating leases in the statement of financial position upon adoption.

In March 2016, the FASB issued authoritative guidance that included several changes to simplify the accounting for stock-based compensation, including the accounting for income taxes, forfeitures, statutory tax withholding requirements and classification of tax benefits in the statement of cash flows. Among the more significant changes, the new guidance requires the income tax effects associated with the settlement of stock-based awards to be recognized through income tax expense rather than directly in equity. Additionally, the income tax effects related to excess tax benefits should be presented within operating cash flows in the statement of cash flows rather than as a financing activity. Excess tax benefits recognized in equity under the prior guidance were $25 million for the nine months ended September 30, 2016. The Company adopted the new guidance effective January 1, 2017 and applied the newly adopted provisions prospectively. Excess tax benefits of $6 million and $32 million were included in Income Taxes in the statement of income for the three and nine month periods ended September 30, 2017, respectively.

The Company intends to complete its assessment in the fourth quarter of 2017.was not material.

In March 2017, the FASB issued authoritative guidance which changes the income statement presentation of the components of net periodic benefit cost related to defined benefit pension and other postretirement plans. The primary change under the new guidance is that only the service cost component of net periodic benefit cost should be included in operating income and is eligible for capitalization as an asset. The other components of net periodic benefit cost such as("other net periodic benefit cost"), including interest cost, the expected return on assets, settlements, curtailments, and amortization of actuarial gains and losses and prior service cost, should be presented below operating income.

The guidance is effective January 1, 2019, with early adoption permitted. The Company elected to early adopt this guidance as of January 1, 2018 and to reclassify the stranded tax effects related to the Act, which resulted in an increase of $45 million to both retained earnings and accumulated other comprehensive loss. Refer to Note 7. Accumulated Other Comprehensive Income (Loss) in Item 1. Financial Statements for additional information.

In February 2016, the FASB issued authoritative guidance to change the criteria for recognizing leasing transactions. Under the new guidance, a lessee will be required to recognize a lease liability and right-of-use lease asset for all leases with a lease term


greater than twelve months, including operating leases, in the statement of financial position. Subsequent measurement, including presentation of expenses and cash flows, will depend on the classification of the lease as either a financing or operating lease.

LIQUIDITY AND CAPITAL RESOURCES

The Company’s primary sources of liquidity are free cash flow and short-term credit facilities. In addition, the Company had $2.8$1.9 billion of cash and equivalents on hand at September 30, 2017March 31, 2018 and also maintains 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 revenue, operating margin, current free cash flow, and credit ratings, it could readily obtain additional financing if necessary.

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.

Cash and equivalents totaled approximately $2.8$1.9 billion as of September 30, 2017March 31, 2018 and $2.5$3.1 billion as of December 31, 2016,2017, primarily all of which was held by international subsidiaries. Cash and equivalents held internationally may be subject to U.S. income taxes and foreign withholding taxes if repatriated to the U.S. CashA portion of the cash and equivalents balances held internationally areis typically used for international operating needs, reinvested to fund expansion of existing international businesses, used to fund new international acquisitions, or used to repay debt held internationally. In the U.S., the Company utilizes cash flows from domestic operations to fund domestic cash needs, which primarily consist of dividend payments, share repurchases, acquisitions, servicing of domestic debt obligations and general corporate needs. The Company also uses its commercial paper program, which is backed by long-term credit facilities, for short-term liquidity needs. The Company believes cash generated domestically and liquidity provided by the Company's commercial paper program will continue to be sufficient to fund cash requirements in the U.S.

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, including a one-time repatriation tax on the deemed repatriation of post-1986 undistributed earnings of foreign subsidiaries. As a result of the one-time repatriation provisions of the Act, the Company provided for substantially all U.S. taxes on the undistributed earnings of its foreign subsidiaries as of December 31, 2017. In the first quarter of 2018, the Company repatriated approximately $1.5 billion of cash and equivalents held by its international subsidiaries, which was primarily used to repay outstanding commercial paper and to fund share repurchases in the quarter.

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. 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. EBITDA and the ratio of total debt to EBITDA are non-GAAP financial measures. 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 September 30, 2017March 31, 2018 and December 31, 20162017 was as follows:
