Accounting Policies [Abstract]
Summary of Accounting Policies	Summary of Accounting Policies Principles of consolidation and presentation The Condensed Consolidated Financial Statements include the accounts of Snap-on Incorporated and its wholly-owned and majority-owned subsidiaries (collectively, “Snap-on” or the “company”). These financial statements should be read in conjunction with, and have been prepared in conformity with, the accounting principles reflected in the consolidated financial statements and related notes included in Snap-on’s 2017 Annual Report on Form 10-K for the fiscal year ended December 30, 2017 (“ 2017 year end”). The company’s 2018 fiscal third quarter ended on September 29, 2018 ; the 2017 fiscal third quarter ended on September 30, 2017 . Each of the company’s 2018 and 2017 fiscal first , second and third quarters contained 13 weeks of operating results. Certain prior year amounts have been reclassified on the Condensed Consolidated Statements of Earnings to conform to the 2018 presentation following the retrospective adoption of ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . The effects of the adjustments to the Condensed Consolidated Statements of Earnings as a result of the adoption of ASU No. 2017-07 for the three and nine month periods ended September 30, 2017 , are as follows: For the three months ended September 30, 2017 For the nine months ended September 30, 2017 As Adjusted As Adjusted Previously for ASU As Previously for ASU As (Amounts in millions) Reported No. 2017-07 Adjusted Reported No. 2017-07 Adjusted Net sales $ 903.8 $ — $ 903.8 $ 2,712.3 $ — $ 2,712.3 Cost of goods sold (455.2 ) 0.2 (455.0 ) (1,352.7 ) 0.7 (1,352.0 ) Gross profit 448.6 0.2 448.8 1,359.6 0.7 1,360.3 Operating expenses (295.5 ) (0.6 ) (296.1 ) (853.3 ) (0.4 ) (853.7 ) Operating earnings before financial services 153.1 (0.4 ) 152.7 506.3 0.3 506.6 Operating earnings from financial services 56.0 — 56.0 163.1 — 163.1 Operating earnings 209.1 (0.4 ) 208.7 669.4 0.3 669.7 Interest expense (13.1 ) — (13.1 ) (38.8 ) — (38.8 ) Other income (expense) - net (2.1 ) 0.4 (1.7 ) (5.7 ) (0.3 ) (6.0 ) Earnings before income taxes and equity earnings $ 193.9 $ — $ 193.9 $ 624.9 $ — $ 624.9 Furthermore, the effects of the adjustments to the Consolidated Statements of Earnings as a result of the adoption of ASU No. 2017-07 for the fiscal years ended December 30, 2017, and December 31, 2016, are as follows: 2017 2016 As Adjusted As Adjusted Previously for ASU As Previously for ASU As (Amounts in millions) Reported No. 2017-07 Adjusted Reported No. 2017-07 Adjusted Net sales $ 3,686.9 $ — $ 3,686.9 $ 3,430.4 $ — $ 3,430.4 Cost of goods sold (1,862.0 ) 1.0 (1,861.0 ) (1,720.8 ) 0.8 (1,720.0 ) Gross profit 1,824.9 1.0 1,825.9 1,709.6 0.8 1,710.4 Operating expenses (1,160.9 ) (0.4 ) (1,161.3 ) (1,054.1 ) 6.1 (1,048.0 ) Operating earnings before financial services 664.0 0.6 664.6 655.5 6.9 662.4 Operating earnings from financial services 217.5 — 217.5 198.7 — 198.7 Operating earnings 881.5 0.6 882.1 854.2 6.9 861.1 Interest expense (52.4 ) — (52.4 ) (52.2 ) — (52.2 ) Other income (expense) - net (7.2 ) (0.6 ) (7.8 ) (0.6 ) (6.9 ) (7.5 ) Earnings before income taxes and equity earnings $ 821.9 $ — $ 821.9 $ 801.4 $ — $ 801.4 Additionally, prior year “Operating earnings” for certain reportable business segments have been adjusted to reflect these reclassifications. See Note 17 for information on Snap-on’s reportable business segments. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for the fair presentation of the Condensed Consolidated Financial Statements for the three and nine month periods ended September 29, 2018 , and September 30, 2017 , have been made. Interim results of operations are not necessarily indicative of the results to be expected for the full fiscal year. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Financial Instruments The fair value of the company’s derivative financial instruments is generally determined using quoted prices in active markets for similar assets and liabilities. The carrying value of the company’s non-derivative financial instruments either approximates fair value, due to their short-term nature, or the amount disclosed for fair value is based upon a discounted cash flow analysis or quoted market values. See Note 9 for further information on financial instruments. Change in Functional Currency Argentina’s economy has been determined to be highly inflationary effective July 1, 2018. As a result, for GAAP reporting, the functional currency for the company’s subsidiary in Argentina changed from the Argentinian Peso to the U.S. Dollar. The impact of the change in functional currency was not material to the Condensed Consolidated Financial Statements for the three and nine months ended September 29, 2018. New Accounting Standards The following new accounting pronouncements were adopted in fiscal year 2018 : In March 2017, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2017-07, which provides additional guidance on the presentation of net periodic pension and postretirement benefit costs in the income statement and on the components eligible for capitalization. The amendments in this ASU require that an employer report the service cost component of the net periodic benefit costs in the same income statement line item as other compensation costs arising from services rendered by employees during the period. The non-service-cost components of net periodic benefit costs are to be presented in the income statement separately from the service cost components and outside a subtotal of income from operations. The ASU also allows for the capitalization of the service cost components, when applicable (i.e., as a cost of internally manufactured inventory or a self-constructed asset). Snap-on adopted this ASU at the beginning of its 2018 fiscal year, with the changes related to the presentation in the statements of earnings of the service cost and non-service-cost components of net periodic benefit costs applied retrospectively, using the practical expedient permitting the use of the amounts disclosed in pension and other postretirement benefit plan notes as the estimation basis for the presentation of the prior comparative periods. For fiscal 2018 and all comparative periods, the non-service-cost components of net periodic benefit costs are included in “Other income (expense) - net” on the accompanying condensed consolidated statements of earnings. Beginning in fiscal 2018, changes related to the capitalization in assets of the service cost component of net periodic benefit costs were applied prospectively. The adoption of this ASU did not have a significant impact on the company’s Condensed Consolidated Statements of Earnings. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740) – Intra-Entity Transfers of Assets Other Than Inventory . The ASU eliminates the requirement to defer the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party. Under the new guidance, an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this ASU were to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings at the time of adoption. The adoption of this ASU did not have an impact on the company’s consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) , which adds and/or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The new guidance is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this ASU did not have a significant impact to the designations of operating, investing and financing activities on the company’s Condensed Consolidated Statements of Cash Flows. On December 31, 2017, the beginning of Snap-on’s 2018 fiscal year, Snap-on adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. Topic 606 is based on the principle that an entity should recognize revenue to depict the transfer of 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. Topic 606 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Snap-on adopted Topic 606 using the modified retrospective approach applied to those contracts that were not completed as of December 31, 2017, which means Topic 606 has been applied to the fiscal 2018 financial statements and disclosures going forward, but that prior period financial statements and disclosures reflect the prior revenue recognition standard. See Note 2 for additional information on revenue recognition. Snap-on’s revenues are primarily from the selling of products that are shipped and billed, services provided to customers and from subscriptions, including software subscriptions. Approximately 90% of net sales are earned at a point in time through ship-and- bill performance obligations. The remaining performance obligations that are recorded over time relate primarily to software subscriptions and to a lesser extent extended warranty and other subscription agreements. Revenues are recognized when control is transferred to customers, in an amount that reflects the consideration Snap-on expects to be entitled to in exchange for those goods and services. Revenue recognition is evaluated through the following five steps: (i) identification of the contract, or contracts, with a customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when or as a performance obligation is satisfied. Revenue related to software subscriptions, as well as extended warranty and other subscription agreements, is generally recognized over time on a ratable basis over the contract term beginning on the date that our service is made available to the customer. Contracts with customers may include multiple performance obligations related to sales of hardware, software and software-related services. For these contracts, individual performance obligations are recorded separately if they are distinct. The transaction price, including any discounts, is allocated to each separate performance obligation based on its relative standalone selling price. The standalone selling prices are determined based on the prices charged to customers or by using an expected cost plus margin approach. The amount assigned to the products or services is recognized when the product is delivered and/or when the services are performed. In instances where the product and/or services are performed over an extended period, as is the case with subscription agreements, revenue is generally recognized over time on a ratable basis using a time-based output method applied over the contract term beginning on the date that the service is made available to the customer. These contracts are generally for 12 months but can be for a term up to 60 months . Franchise fee revenue, including nominal, non-refundable initial fees, is recognized upon the granting of a franchise, which is when the company has performed substantially all initial services required by the franchise agreement. Franchise fee revenue also includes ongoing monthly fees (primarily for sales and business training as well as marketing and product promotion programs) that are recognized as the fees are earned. Franchise fee revenue totaled $ 3.9 million and $ 12.0 million for the three and nine month periods ended September 29, 2018 , respectively. The following new accounting pronouncements, and related impacts on adoption, are being evaluated by the company: In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement , which is designed to improve the effectiveness of disclosures by removing, modifying and adding disclosures related to fair value measurements. ASU No. 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years; the ASU allows for early adoption in any interim period after issuance of the update. The company is currently assessing the impact this ASU will have on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General Subtopic 715-20 - Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans, which is designed to improve the effectiveness of disclosures by removing and adding disclosures related to defined benefit plans. ASU No. 2018-14 is effective for fiscal years ending after December 15, 2020; the ASU allows for early adoption in any year end after issuance of the update. The company is currently assessing the impact this ASU will have on its consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220) , which allows for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from “H.R.1”, formerly known as the Tax Cuts and Jobs Act (the “Tax Act”). ASU No. 2018-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years; the ASU allows for early adoption in any interim period after issuance of the update. The adoption of this ASU is not expected to have a significant impact on the company’s consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities , which improves the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments in this update also make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. ASU No. 2017-12 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years; the ASU allows for early adoption in any interim period after issuance of the update. The adoption of this ASU is not expected to have a significant impact on the company’s consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) , to require the measurement of expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable forecasts. The main objective of this ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. ASU No. 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years; the ASU allows for early adoption as of the beginning of an interim or annual reporting period beginning after December 15, 2018. The company is currently assessing the impact this ASU will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The ASU is intended to represent an improvement over previous GAAP, which did not require lease assets and lease liabilities to be recognized for most leases. This ASU, which supersedes most current lease guidance, affects any entity that enters into a lease (as that term is defined in the ASU), with some specified scope exemptions. ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years; the ASU allows for early adoption as of the beginning of an interim or annual reporting period. Snap-on commenced its assessment of Topic 842 during the second half of 2017 and developed a comprehensive project plan that included representatives from across the company’s business segments. The project plan included evaluating Snap-on’s lease portfolio, analyzing the standard’s impact on the company’s various types of lease contracts and identifying the reporting requirements of the new standard. The company is in the process of identifying and implementing appropriate changes to its business processes, systems and controls to support lease accounting and disclosures under Topic 842. As of September 29, 2018, and subject to the company’s ongoing evaluation of new lease contracts, the company has made further progress with its evaluation of the expected impact of adopting Topic 842 and anticipates that the adoption of this standard will not have a significant impact on the company’s consolidated financial statements. As a result of the adoption of this standard, a right-of-use asset and a related lease liability will be established to reflect the present value of the future lease payments at a level comparable to those reported in Snap-on’s 2017 Annual Report on Form 10-K.

Revenue Recognition and Deferred Revenue [Abstract]
Revenue Recognition	Revenue Recognition Snap-on recognizes revenue from the sale of tools, diagnostic and equipment products and related services based on when control of the product passes to the customer or the service is provided and is recognized at an amount that reflects the consideration expected to be received in exchange for such goods or services. The effects of adjustments to the December 30, 2017 consolidated balance sheet for the adoption of Topic 606 were as follows: Balance at Topic 606 Opening Balance at (Amounts in millions) December 30, 2017 Adjustments December 31, 2017 Assets Inventories - net $ 638.8 $ 20.9 $ 659.7 Deferred income tax assets 52.0 0.6 52.6 Liabilities and Equity Other accrued liabilities $ 388.1 $ 23.3 $ 411.4 Retained earnings 3,772.3 (1.8 ) 3,770.5 The adoption of Topic 606 did not have a significant impact on the company’s consolidated financial statements. The adoption resulted in the recognition of an inventory asset related to certain product returns by increasing the returns liability and recognizing an inventory asset for the anticipated value of the returns to recognize Snap-on’s contractual obligation to recover products from customers; this gross up had no corresponding impact on the Condensed Consolidated Statement of Earnings. For the anticipated value of the returns, the adoption resulted in the recognition of an increase in the inventory obsolescence reserve of $2.4 million with a corresponding adjustment to fiscal 2018 beginning retained earnings. Other than the amounts recorded for the adoption of Topic 606 on the Condensed Consolidated Balance Sheets, there were no other changes since the adoption that would be materially different from previous accounting standards that would affect the Condensed Consolidated Statements of Earnings, Balance Sheets, or Cash Flows.

The tools product category includes hand tools, power tools, tool storage products and other similar products. The diagnostics, information and management systems product category includes handheld and PC-based diagnostic products, service and repair information products, diagnostic software solutions, electronic parts catalogs, business management systems and services, point-of-sale systems, integrated systems for vehicle service shops, original equipment manufacturer (“OEM”) purchasing facilitation services, and warranty management systems and analytics to help OEM dealership service and repair shops (“OEM dealerships”) manage and track performance. The equipment product category includes solutions for the service of vehicles and industrial equipment. Snap-on supports the sale of its diagnostics and vehicle service shop equipment by offering training programs as well as after-sales support to its customers. Through its financial services businesses, Snap‑on also derives revenue from various financing programs designed to facilitate the sales of its products and support its franchise business. Approximately 90% of Snap-on’s net sales are products sold at a point in time through ship-and-bill performance obligations that also includes service repair services. The remaining sales revenue is earned over time primarily on a subscription basis including software, extended warranty and other subscription service agreements. Snap-on enters into contracts related to the selling of tools, diagnostic and repair information and equipment products and related services. At contract inception, an assessment of the goods and services promised in the contracts with customers is performed and a performance obligation is identified for each distinct promise to transfer to the customer a good or service (or bundle of goods or services). To identify the performance obligations, Snap-on considers all of the goods or services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. Contracts with customers are comprised of customer purchase orders, invoices and written contracts. When Performance Obligations Are Satisfied For performance obligations related to the majority of ship-and-bill products, including repair services contracts, control transfers at a point in time when title transfers upon shipment of the product to the customer, and for some sales, control transfers when title is transferred at time of receipt by customer. Once a product or repaired product has shipped or has been delivered, the customer is able to direct the use of, and obtain substantially all of the remaining benefits from the asset, revenue is recognized. Snap-on considers control to have transferred upon shipment or delivery when Snap-on has a present right to payment, the customer has legal title to the asset, Snap-on has transferred physical possession of the asset, and the customer has significant risk and rewards of ownership of the asset. For performance obligations related to software subscriptions, extended warranties and other subscription agreements, Snap-on transfers control and recognizes revenue over time on a ratable basis using a time-based output method. The performance obligations are typically satisfied as services are rendered on a straight-line basis over the contract term, which is generally for 12 months but can be for a term up to 60 months . Significant Payment Terms For ship-and-bill type contracts with customers, the contract states the final terms of the sale, including the description, quantity, and price of each product or service purchased. Payment terms are typically due upon delivery or up to 30 days after delivery but can range up to 120 days after delivery. For subscription contracts, payment terms are in advance or in arrears of services on a monthly, quarterly or annual basis over the contract term, which is generally for 12 months but can be for a term up to 60 months depending on the product or service. The customer typically agrees to a stated rate and price in the contract that does not vary over the contract term. In some cases, customers prepay for their licenses, or in other cases, pay on a monthly or quarterly basis. When the timing of the payment made by the customer precedes the delivery of the performance obligation, a contract liability is recognized. Variable Consideration In some cases, the nature of Snap-on’s contracts give rise to variable consideration, including rebates, credits, allowances for returns or other similar items that generally decrease the transaction price. These variable amounts generally are credited to the customer, based on achieving certain levels of sales activity, product returns and making payments within specific terms. In the normal course of business, Snap-on allows franchisees to return product per the provisions in the franchise agreement that allow for the return of product in a saleable condition. For other customers, product returns are generally not accepted unless the item is defective as manufactured. Where applicable, Snap-on establishes provisions for estimated sales returns. Estimated product returns are recorded as a reduction in reported revenues at the time of sale based upon historical product return experience and is adjusted for known trends to arrive at the amount of consideration to which Snap-on expects to receive. Variable consideration is estimated at the most likely amount that is expected to be earned. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the anticipated performance and all information (historical, current and forecasted) that is reasonably available. Warranties Snap-on allows customers to return product when the product is defective as manufactured. Where applicable, Snap-on establishes provisions for estimated warranties. Estimated product warranties are provided for specific product lines and Snap-on accrues for estimated future warranty cost in the period in which the sale is recorded. The costs are included in “Cost of goods sold” on the accompanying Condensed Consolidated Statements of Earnings. Snap-on calculates its accrual requirements based on historic warranty loss experience that is periodically adjusted for recent actual experience, including the timing of claims during the warranty period and actual costs incurred. Snap-on does not typically provide customers with the right to a refund. Practical Expedients and Exemptions Snap-on typically expenses incremental direct costs of obtaining a contract (sales commissions) when incurred because the amortization period is generally 12 months or less. Capitalized long-term contract costs are not significant. Contract costs are expensed or amortized in “Operating expenses” on the accompanying Condensed Consolidated Statements of Earnings. Snap-on elected to account for shipping and handling activities that occur after control of the related good transfers to the customer as fulfillment activities and are therefore recognized upon shipment of the goods. Snap-on has applied the portfolio approach to its ship-and-bill contracts that have similar characteristics as it reasonably expects that the effects on the financial statements of applying this guidance to the portfolio of contracts would not differ materially from applying this guidance to the individual contracts within the portfolio. Snap-on typically excludes from its sales transaction price any amounts collected from customers for sales (and similar) taxes. For certain performance obligations related to software subscriptions, extended warranty and other subscription agreements that are settled over time, Snap-on has elected not to disclose the value of unsatisfied performance obligations for: (i) contracts that have an original expected length of one year or less; (ii) contracts where revenue is recognized as invoiced; and (iii) contracts with variable consideration related to unsatisfied performance obligations. The remaining duration of these unsatisfied performance obligations range from one month up to 60 months . Snap-on had approximately $223.0 million of long-term contracts that have fixed consideration that extends beyond one year as of September 29, 2018 . Snap-on expects to recognize approximately 50% of these contracts as revenue by the end of fiscal 2019, an additional 40% by the end of fiscal 2021 and the balance thereafter. Contract Liabilities (Deferred Revenues) Contract liabilities are recorded when cash payments are received in advance of Snap-on’s performance. The timing of payment is typically on a monthly, quarterly or annual basis. The balance of total contract liabilities at September 29, 2018 , was $63.4 million and was $49.4 million at the beginning of fiscal 2018. The current portion of contract liabilities and the non-current portion are included in “Other accrued liabilities” and “Other long-term liabilities”, respectively, on the accompanying Condensed Consolidated Balance Sheets. For the first nine months of 2018, Snap-on recognized revenue of $34.6 million that was included in the contract liability balance as of December 30, 2017, which was primarily from the amortization of software subscriptions, extended warranties and other subscription agreements. The increase in the total contract liabilities balance is primarily driven by the timing of cash payments received or due in advance of satisfying Snap-on’s performance obligations and growth in certain software subscriptions, partially offset by revenues recognized that were included in the contract liability balance at the beginning of the period. Revenue Recognition Prior to 2018 Revenue recognition for fiscal 2017, as presented, is based on Revenue Recognition (Topic 605). Snap-on recognized revenue from the sale of tools and diagnostic and equipment products when contract terms were met, the price was fixed or determinable, collectability was reasonably assured and a product was shipped or risk of ownership had been transferred to and accepted by the customer. For sales contingent upon customer acceptance, revenue recognition was deferred until such obligations were fulfilled. Estimated product returns were recorded as a reduction in reported revenues at the time of sale based upon historical product return experience and gross profit margin was adjusted for known trends. Provisions for customer volume rebates, discounts and allowances were also recorded as a reduction in reported revenues at the time of sale based on historical experience and known trends. Revenue related to extended warranty and subscription agreements was recognized over the terms of the respective agreements. Snap-on also recognized revenue related to multiple element arrangements, including sales of hardware, software and software-related services. When a sales arrangement contained multiple elements, such as hardware and software products and/or services, Snap‑on used the relative selling price method to allocate revenues between hardware and software elements. For software elements that were not essential to the hardware’s functionality and related software post-contract customer support, vendor specific objective evidence (“VSOE”) of fair value was used to further allocate revenue to each element based on its relative fair value and, when necessary, the residual method was used to assign value to the delivered elements when VSOE only existed for the undelivered elements. The amount assigned to the products or services was recognized when the product was delivered and/or when the services were performed. In instances where the product and/or services were performed over an extended period, as is the case with subscription agreements or the providing of ongoing support, revenue was generally recognized on a straight-line basis over the term of the agreement, which generally ranged from 12 months to 60 months . Franchise fee revenue, including nominal, non-refundable initial fees, was recognized upon the granting of a franchise, which was when the company performed substantially all initial services required by the franchise agreement. Franchise fee revenue also included ongoing monthly fees (primarily for sales and business training as well as marketing and product promotion programs) that were recognized as the fees were earned. Franchise fee revenue totaled $4.3 million and $11.2 million for the three and nine month periods ended September 30, 2017 , respectively.

Receivables [Abstract]
Receivables	Receivables Trade and Other Accounts Receivable Snap-on’s trade and other accounts receivable primarily arise from the sale of tools and diagnostic and equipment products to a broad range of industrial and commercial customers and to Snap-on’s independent franchise van channel on a non-extended-term basis with payment terms generally ranging from 30 to 120 days . The components of Snap-on’s trade and other accounts receivable as of September 29, 2018 , and December 30, 2017 , are as follows: (Amounts in millions) September 29, December 30, Trade and other accounts receivable $ 696.3 $ 690.2 Allowances for doubtful accounts (17.6 ) (14.6 ) Total trade and other accounts receivable – net $ 678.7 $ 675.6 Finance and Contract Receivables Snap-on Credit LLC (“SOC”), the company’s financial services operation in the United States, originates extended-term finance and contract receivables on sales of Snap-on’s products sold through the U.S. franchisee and customer network and to certain other customers of Snap-on; Snap-on’s foreign finance subsidiaries provide similar financing internationally. Interest income on finance and contract receivables is included in “Financial services revenue” on the accompanying Condensed Consolidated Statements of Earnings. Snap-on’s finance receivables are comprised of extended-term installment payment contracts to both technicians and independent shop owners (i.e., franchisees’ customers) to enable them to purchase tools and diagnostic and equipment products on an extended-term payment plan, generally with average payment terms approaching four years . Contract receivables, with payment terms of up to 10 years , are comprised of extended-term installment payment contracts to a broad base of customers worldwide, including shop owners, both independents and national chains, for their purchase of tools and diagnostic and equipment products. Contract receivables also include extended-term installment loans to franchisees to meet a number of financing needs, including working capital loans, loans to enable new franchisees to fund the purchase of the franchise and van leases. Finance and contract receivables are generally secured by the underlying tools and/or diagnostic or equipment products financed and, for installment loans to franchisees, other franchisee assets. The components of Snap-on’s current finance and contract receivables as of September 29, 2018 , and December 30, 2017 , are as follows: (Amounts in millions) September 29, December 30, Finance receivables, net of unearned finance charges of $21.4 million and $21.0 million, respectively $ 538.2 $ 523.1 Contract receivables, net of unearned finance charges of $19.2 million and $17.6 million, respectively 106.9 98.1 Total 645.1 621.2 Allowances for doubtful accounts: Finance receivables (19.2 ) (17.7 ) Contract receivables (1.3 ) (1.3 ) Total (20.5 ) (19.0 ) Total current finance and contract receivables – net $ 624.6 $ 602.2 Finance receivables – net $ 519.0 $ 505.4 Contract receivables – net 105.6 96.8 Total current finance and contract receivables – net $ 624.6 $ 602.2 The components of Snap-on’s finance and contract receivables with payment terms beyond one year as of September 29, 2018 , and December 30, 2017 , are as follows: (Amounts in millions) September 29, December 30, Finance receivables, net of unearned finance charges of $17.3 million and $16.7 million, respectively $ 1,098.7 $ 1,078.0 Contract receivables, net of unearned finance charges of $28.5 million and $25.5 million, respectively 341.4 325.9 Total 1,440.1 1,403.9 Allowances for doubtful accounts: Finance receivables (40.4 ) (38.8 ) Contract receivables (3.3 ) (3.3 ) Total (43.7 ) (42.1 ) Total long-term finance and contract receivables – net $ 1,396.4 $ 1,361.8 Finance receivables – net $ 1,058.3 $ 1,039.2 Contract receivables – net 338.1 322.6 Total long-term finance and contract receivables – net $ 1,396.4 $ 1,361.8 Delinquency is the primary indicator of credit quality for finance and contract receivables. The entire receivable balance of a contract is considered delinquent when contractual payments become 30 days past due. Depending on the contract, payments for finance and contract receivables are due on a monthly or weekly basis. Weekly payments are converted into a monthly equivalent for purposes of calculating delinquency. Delinquencies are assessed at the end of each month following the monthly equivalent due date. Removal from delinquent status occurs when the cumulative number of monthly payments due has been received by the company. Finance receivables are generally placed on nonaccrual status (nonaccrual of interest and other fees): (i) when a customer is placed on repossession status; (ii) upon receipt of notification of bankruptcy; (iii) upon notification of the death of a customer; or (iv) in other instances in which management concludes collectability is not reasonably assured. Finance receivables that are considered nonperforming include receivables that are on nonaccrual status and receivables that are generally more than 90 days past due. Contract receivables are generally placed on nonaccrual status: (i) when a receivable is more than 90 days past due or at the point a customer’s account is placed on terminated status regardless of its delinquency status; (ii) upon notification of the death of a customer; or (iii) in other instances in which management concludes collectability is not reasonably assured. Contract receivables that are considered nonperforming include receivables that are on nonaccrual status and receivables that are generally more than 90 days past due. The accrual of interest and other fees is resumed when the finance or contract receivable becomes contractually current and collection of all remaining contractual amounts due is reasonably assured. Finance and contract receivables are evaluated for impairment on a collective basis. A receivable is impaired when it is probable that all amounts related to the receivable will not be collected according to the contractual terms of the applicable agreement. Impaired finance and contract receivables are covered by the company’s respective allowances for doubtful accounts and are charged-off against the allowances when appropriate. As of September 29, 2018 , and December 30, 2017 , there were $27.8 million and $28.0 million , respectively, of impaired finance receivables, and there were $4.7 million and $2.3 million , respectively, of impaired contract receivables. It is the general practice of Snap-on’s financial services business to not engage in contract or loan modifications.

Significant and unanticipated changes in circumstances, such as declines in profitability and cash flow due to significant and long-term deterioration in macroeconomic, industry and market conditions, the loss of key customers, changes in technology or markets, significant changes in key personnel or litigation, a significant and sustained decrease in share price and/or other events, including effects from the sale or disposal of a reporting unit, could require a provision for impairment of goodwill and/or other intangible assets in a future period. As of September 29, 2018 , the company had no accumulated impairment losses. The weighted-average amortization periods related to other intangible assets are as follows: In Years Customer relationships 15 Developed technology 3 Internally developed software 4 Patents 8 Trademarks 6 Other 39 Snap-on is amortizing its customer relationships on both an accelerated and straight-line basis over a 15 -year weighted-average life; the remaining intangibles are amortized on a straight-line basis. The weighted-average amortization period for all amortizable intangibles on a combined basis is 11 years . The company’s customer relationships generally have contractual terms of three to five years and are typically renewed without significant cost to the company. The weighted-average 15 -year life for customer relationships is based on the company’s historical renewal experience. Intangible asset renewal costs are expensed as incurred. The aggregate amortization expense was $6.2 million and $19.2 million for the respective three and nine months ended September 29, 2018 , and $7.1 million and $20.7 million for the respective three and nine months ended September 30, 2017 . Based on current levels of amortizable intangible assets and estimated weighted-average useful lives, estimated annual amortization expense is expected to be $25.4 million in 2018 , $23.2 million in 2019 , $19.3 million in 2020 , $16.0 million in 2021 , $14.4 million in 2022 , and $12.5 million in 2023 .

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Snap-on’s effective income tax rate on earnings attributable to Snap-on was 24.6% and 30.5% in the first nine months of 2018 and 2017 , respectively. The effective tax rate for 2018 includes the net tax benefits attributable to the Tax Act, which was signed into law on December 22, 2017. The Tax Act made broad and complex changes to the U.S. tax code, including, but not limited to, (i) reducing the U.S. federal corporate tax rate from 35 percent to 21 percent; and (ii) requiring companies to pay a one-time transition tax on certain unremitted earnings of foreign subsidiaries. The Tax Act also established new tax laws that affect 2018 , including, but not limited to: (i) the reduction of the U.S. federal corporate tax rate discussed above; (ii) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (iii) a new provision designed to tax global intangible low-taxed income (“GILTI”); (iv) the repeal of the domestic production activity deductions; (v) limitations on the deductibility of certain executive compensation; (vi) limitations on the use of foreign tax credits to reduce the U.S. income tax liability; and (vii) a new provision that allows a domestic corporation an immediate deduction for a portion of its foreign derived intangible income (“FDII”). The Securities and Exchange Commission staff issued Staff Accounting Bulletin (“SAB”) 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the related accounting under ASC 740, Accounting for Income Taxes . In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for a certain income tax effect of the Tax Act is incomplete, but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. The company’s accounting for the certain elements of the Tax Act was incomplete as of the period ended December 30, 2017 , and remains incomplete as of September 29, 2018 . However, the company was able to make reasonable estimates of the effects and, therefore, recorded provisional estimates for these items. In connection with its initial analysis of the impact of the Tax Act, the company recorded a provisional discrete net tax expense of $7.0 million in the period ended December 30, 2017 . This provisional estimate consists of a net expense of $13.7 million for the one-time transition tax and a net benefit of $6.7 million related to revaluation of deferred tax assets and liabilities, caused by the new lower corporate tax rate. To determine the transition tax, the company must determine the amount of post-1986 accumulated earnings and profits of the relevant subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. While the company was able to make a reasonable estimate of the transition tax, it is continuing to gather additional information to more precisely compute the final amount. Likewise, while the company was able to make a reasonable estimate of the impact of the reduction to the corporate tax rate, its rate may be affected by other analyses related to the Tax Act, including, but not limited to, the state tax effect of adjustments made to federal temporary differences. Due to the complexity of the new GILTI tax rules, the company is continuing to evaluate this provision of the Tax Act and the application of ASC 740. Under GAAP, the company is allowed to make an accounting policy choice to either (i) treat taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”); or (ii) factor in such amounts into a company’s measurement of its deferred taxes (the “deferred method”). The company’s selection of an accounting policy with respect to the new GILTI tax rules is dependent on additional analysis and potential future modifications to existing structures, which are not currently known. The company has not made a policy decision regarding whether to record deferred taxes on GILTI. The company will continue to analyze the full effects of the Tax Act on its consolidated financial statements. During the first nine months of 2018, the Internal Revenue Service issued new guidance affecting the computation of the company’s 2017 federal income tax liability. As a result of this new guidance and additional analysis of the impacts of the Tax Act, the company revised its prior estimates and recorded $1.8 million and $3.9 million of net tax expense related to the Tax Act during the respective three and nine months ended September 29, 2018 . The ultimate impact of the Tax Act may differ from the current estimates, possibly materially, due to changes in interpretations and assumptions the company has made, future guidance that may be issued and actions the company may take as a result of the law. Snap-on and its subsidiaries file income tax returns in the United States and in various state, local and foreign jurisdictions. It is reasonably possible that certain unrecognized tax benefits may either be settled with taxing authorities or the statutes of limitations for such items may lapse within the next 12 months, causing Snap-on’s gross unrecognized tax benefits to decrease by a range of zero to $0.8 million . Over the next 12 months, Snap-on anticipates taking certain tax positions on various tax returns for which the related tax benefit does not meet the recognition threshold. Accordingly, Snap-on’s gross unrecognized tax benefits may increase by a range of zero to $1.5 million over the next 12 months for uncertain tax positions expected to be taken in future tax filings.

Notes payable and current maturities of long-term debt of $164.5 million as of September 29, 2018 , included $154.0 million of commercial paper borrowings and $10.5 million of other notes. As of 2017 year end, notes payable and current maturities of long-term debt of $ 433.2 million included $ 250 million of unsecured 4.25% notes due on January 16, 2018 (the “2018 Notes”), that were repaid upon maturity in accordance with their terms, $ 151.0 million of commercial paper borrowings and $ 32.2 million of other notes. As of 2017 year end, $200 million of unsecured 6.70% notes due March 1, 2019 (the “2019 Notes”) were included in “Long-term debt” on the accompanying Condensed Consolidated Balance Sheets as their scheduled maturity was in excess of one year of the 2017 year-end balance sheet date. On February 20, 2018, Snap-on commenced a tender offer to repurchase the 2019 Notes with $26.1 million of the 2019 Notes tendered and repaid on February 27, 2018. On February 20, 2018, Snap-on also issued a notice of redemption for remaining outstanding 2019 Notes not tendered, with the redemption completed on March 22, 2018. The total cash cost for this tender and redemption was $209.1 million, including accrued interest of $1.5 million. Snap-on recorded $7.8 million for the loss on the early extinguishment of debt related to the 2019 Notes, which included the redemption premium and other issuance costs associated with this debt in “Other income (expense) - net” on the accompanying Condensed Consolidated Statement of Earnings. See Note 15 for additional information on Other income (expense) - net. On February 20, 2018, Snap-on sold, at a discount, $ 400 million of unsecured 4.10% long-term notes that mature on March 1, 2048 (the “2048 Notes”). Interest on the 2048 Notes is payable semi-annually beginning September 1, 2018. Snap-on used a portion of the $ 395.4 million of net proceeds from the sale of the 2048 Notes, reflecting $ 3.5 million of transaction costs, to repay the 2019 Notes. The remaining net proceeds were used to repay a portion of its then-outstanding commercial paper borrowings and for general corporate purposes. Snap-on has a five -year, $700 million multi-currency revolving credit facility that terminates on December 15, 2020 (the “Credit Facility”); no amounts were outstanding under the Credit Facility as of September 29, 2018 . Borrowings under the Credit Facility bear interest at varying rates based on Snap-on’s then-current, long-term debt ratings. The Credit Facility’s financial covenant requires that Snap-on maintain, as of each fiscal quarter end, either (i) a ratio not greater than 0.60 to 1.00 of consolidated net debt (consolidated debt net of certain cash adjustments) to the sum of such consolidated net debt plus total equity and less accumulated other comprehensive income or loss (the “Debt Ratio”); or (ii) a ratio not greater than 3.50 to 1.00 of such consolidated net debt to earnings before interest, taxes, depreciation, amortization and certain other adjustments for the preceding four fiscal quarters then ended (the “Debt to EBITDA Ratio”). Snap-on may, up to two times during any five -year period during the term of the Credit Facility (including any extensions thereof), increase the maximum Debt Ratio to 0.65 to 1.00 and/or increase the maximum Debt to EBITDA Ratio to 3.75 to 1.00 for four consecutive fiscal quarters in connection with certain material acquisitions (as defined in the related credit agreement). As of September 29, 2018 , the company’s actual ratios of 0.23 and 1.00 , respectively, were both within the permitted ranges set forth in this financial covenant. Snap-on generally issues commercial paper to fund its financing needs on a short-term basis and uses the Credit Facility as back-up liquidity to support such commercial paper issuances.

Financial Instruments

Financial Instruments	9 Months Ended

Investments, All Other Investments [Abstract]
Financial Instruments	Financial Instruments Derivatives: All derivative instruments are reported in the Condensed Consolidated Financial Statements at fair value. Changes in the fair value of derivatives are recorded each period in earnings or on the accompanying Condensed Consolidated Balance Sheets, depending on whether the derivative is designated and effective as part of a hedged transaction. Gains or losses on derivative instruments recorded in Accumulated other comprehensive income (loss) (“Accumulated OCI”) must be reclassified to earnings in the period in which earnings are affected by the underlying hedged item and the ineffective portion of all hedges must be recognized in earnings in the period that such portion is determined to be ineffective. The criteria used to determine if hedge accounting treatment is appropriate are: (i) the designation of the hedge to an underlying exposure; (ii) whether or not overall risk is being reduced; and (iii) if there is a correlation between the value of the derivative instrument and the underlying hedged item. On the date a derivative contract is entered into, Snap-on designates the derivative as a fair value hedge, a cash flow hedge, a hedge of a net investment in a foreign operation, or a natural hedging instrument whose change in fair value is recognized as an economic hedge against changes in the value of the hedged item. Snap-on does not use derivative instruments for speculative or trading purposes. The company is exposed to global market risks, including the effects of changes in foreign currency exchange rates, interest rates, and the company’s stock price, and therefore uses derivatives to manage financial exposures that occur in the normal course of business. The primary risks managed by using derivative instruments are foreign currency risk, interest rate risk and stock-based deferred compensation risk. Foreign Currency Risk Management: Snap-on has significant international operations and is subject to certain risks inherent with foreign operations that include currency fluctuations. Foreign currency exchange risk exists to the extent that Snap-on has payment obligations or receipts denominated in currencies other than the functional currency, including intercompany loans denominated in foreign currencies. To manage these exposures, Snap-on identifies naturally offsetting positions and then purchases hedging instruments to protect the residual net exposures. Snap-on manages most of these exposures on a consolidated basis, which allows for netting of certain exposures to take advantage of natural offsets. Foreign currency forward contracts (“foreign currency forwards”) are used to hedge the net exposures. Gains or losses on net foreign currency hedges are intended to offset losses or gains on the underlying net exposures in an effort to reduce the earnings volatility resulting from fluctuating foreign currency exchange rates. Snap-on’s foreign currency forwards are typically not designated as hedges. The fair value changes of these contracts are reported in earnings as foreign exchange gain or loss, which is included in “Other income (expense) – net” on the accompanying Condensed Consolidated Statements of Earnings. Interest Rate Risk Management: Snap-on aims to control funding costs by managing the exposure created by the differing maturities and interest rate structures of Snap-on’s borrowings through the use of interest rate swap agreements (“interest rate swaps”) and treasury lock agreements (“treasury locks”). Snap-on enters into interest rate swaps to manage risks associated with changing interest rates related to the company’s fixed rate borrowings. Interest rate swaps are accounted for as fair value hedges. The differentials paid or received on interest rate swaps are recognized as adjustments to “Interest expense” on the accompanying Condensed Consolidated Statements of Earnings. The effective portion of the change in fair value of the derivative is recorded in “Long-term debt” on the accompanying Condensed Consolidated Balance Sheets, while any ineffective portion is recorded as an adjustment to “Interest expense” on the accompanying Condensed Consolidated Statements of Earnings. The notional amount of interest rate swaps outstanding and designated as fair value hedges was $ 100 million as of both September 29, 2018 , and December 30, 2017 . Snap-on entered into a $300 million treasury lock in the fourth quarter of 2017 to manage the potential change in interest rates in anticipation of the possible issuance of fixed rate debt in the first quarter of 2018. Treasury locks are accounted for as cash flow hedges. The effective differentials to be paid or received on treasury locks related to the anticipated issuance of fixed rate debt are initially recorded in Accumulated OCI, net of tax effect. In the first quarter of 2018, Snap-on settled the outstanding $300 million treasury lock after it was deemed to be an ineffective hedge related to the 2048 Notes which were issued in February 2018. The $13.3 million gain on the settlement of the treasury lock was recorded in “Other income (expense) - net” on the accompanying Condensed Consolidated Statements of Earnings. As of September 29, 2018 , no treasury locks were outstanding. The notional amount of treasury locks outstanding and designated as cash flow hedges as of December 30, 2017 , was $300 million . See Note 15 for additional information on Other income (expense) - net. In first quarter of 2017, Snap-on settled the $250 million treasury lock in conjunction with the February 2017 issuance of the 2027 Notes. The $14.9 million gain on the settlement of the treasury lock was recorded in Accumulated OCI and is being amortized over the term of the 2027 Notes and recognized as an adjustment to interest expense on the Condensed Consolidated Statements of Earnings. Stock-based Deferred Compensation Risk Management: Snap-on aims to manage market risk associated with the stock-based portion of its deferred compensation plans through the use of prepaid equity forward agreements (“equity forwards”). Equity forwards are used to aid in offsetting the potential mark-to-market effect on stock-based deferred compensation from changes in Snap-on’s stock price. Since stock-based deferred compensation liabilities increase as the company’s stock price rises and decrease as the company’s stock price declines, the equity forwards are intended to mitigate the potential impact on deferred compensation expense that may result from such mark-to-market changes. As of September 29, 2018 , Snap-on had equity forwards in place intended to manage market risk with respect to 95,300 shares of Snap-on common stock associated with its deferred compensation plans. Counterparty Risk: Snap-on is exposed to credit losses in the event of non-performance by the counterparties to its various financial agreements, including its foreign currency forward contracts, interest rate swap agreements, treasury lock agreements and prepaid equity forward agreements. Snap-on does not obtain collateral or other security to support financial instruments subject to credit risk, but monitors the credit standing of the counterparties and generally enters into agreements with financial institution counterparties with a credit rating of A- or better. Snap-on does not anticipate non-performance by its counterparties, but cannot provide assurances. Fair Value of Financial Instruments: The fair values of financial instruments that do not approximate the carrying values in the financial statements are as follows: September 29, 2018 December 30, 2017 (Amounts in millions) Carrying Value Fair Value Carrying Value Fair Value Finance receivables – net $ 1,577.3 $ 1,820.7 $ 1,544.6 $ 1,791.5 Contract receivables – net 443.7 481.1 419.4 459.1 Long-term debt, notes payable and current maturities of long-term debt 1,109.3 1,112.1 1,186.8 1,235.6 The following methods and assumptions were used in estimating the fair value of financial instruments: • Finance and contract receivables include both short-term and long-term receivables. The fair value estimates of finance and contract receivables are derived utilizing discounted cash flow analyses performed on groupings of receivables that are similar in terms of loan type and characteristics. The cash flow analyses consider recent prepayment trends where applicable. The cash flows are discounted over the average life of the receivables using a current market discount rate of a similar term adjusted for credit quality. Significant inputs to the fair value measurements of the receivables are unobservable and, as such, are classified as Level 3. • Fair value of long-term debt and current maturities of long-term debt were estimated, using Level 2 fair value measurements, based on quoted market values of Snap-on’s publicly traded senior debt. The carrying value of long-term debt includes adjustments related to fair value hedges. The fair value of notes payable approximates such instruments’ carrying value due to their short-term nature. • The fair value of financial instruments, including trade and other accounts receivable, accounts payable and other financial instruments, approximates such instruments’ carrying value due to their short-term nature.

As of September 29, 2018 , the 2011 Plan had 2,638,001 shares available for future grants. The company uses treasury stock to deliver shares under both the 2001 and 2011 Plans. Net stock-based compensation expense was $8.0 million and $ 22.6 million for the respective three and nine months ended September 29, 2018 , and $ 7.0 million and $ 21.4 million for the respective three and nine months ended September 30, 2017 . Cash received from stock purchase and option plan exercises during the respective three and nine months ended September 29, 2018 , totaled $ 25.8 million and $ 54.1 million. Cash received from stock purchase and option plan exercises during the respective three and nine months ended September 30, 2017 , totaled $1.6 million and $ 36.2 million. The tax benefit realized from both the exercise and vesting of share-based payment arrangements was $ 4.5 million and $ 12.1 million for the respective three and nine months ended September 29, 2018 , and $ 0.8 million and $ 12.9 million for the respective three and nine months ended September 30, 2017 . Stock Options Stock options are granted with an exercise price equal to the market value of a share of Snap-on’s common stock on the date of grant and have a contractual term of ten years . Stock option grants vest ratably on the first, second and third anniversaries of the date of grant. The fair value of each stock option award is estimated on the date of grant using the Black-Scholes valuation model. The company uses historical data regarding stock option exercise and forfeiture behaviors for different participating groups to estimate the period of time that options granted are expected to be outstanding. Expected volatility is based on the historical volatility of the company’s stock for the length of time corresponding to the expected term of the option. The expected dividend yield is based on the company’s historical dividend payments. The risk-free interest rate is based on the U.S. treasury yield curve on the grant date for the expected term of the option. The following weighted-average assumptions were used in calculating the fair value of stock options granted during the nine months ended September 29, 2018 , and September 30, 2017 , using the Black-Scholes valuation model; there were no stock options granted during the three months ended September 29, 2018 , or September 30, 2017 : Nine Months Ended September 29, September 30, Expected term of option (in years) 5.35 5.15 Expected volatility factor 20.08% 22.01% Expected dividend yield 1.68% 1.63% Risk-free interest rate 2.71% 1.78% A summary of stock option activity as of and for the nine months ended September 29, 2018 , is presented below: Shares (in thousands) Exercise Price Per Share* Remaining Contractual Term* (in years) Aggregate Intrinsic Value (in millions) Outstanding at December 30, 2017 3,198 $ 115.30 Granted 515 161.18 Exercised (496 ) 88.30 Forfeited or expired (34 ) 159.17 Outstanding at September 29, 2018 3,183 126.45 6.4 $ 181.9 Exercisable at September 29, 2018 2,089 108.93 5.3 156.0 * Weighted-average The weighted-average grant date fair value of options granted during the nine months ended September 29, 2018 , and September 30, 2017 , was $30.21 and $31.13 , respectively. The intrinsic value of options exercised was $ 18.1 million and $ 39.3 million during the respective three and nine months ended September 29, 2018 , and $ 2.0 million and $23.4 million during the respective three and nine months ended September 30, 2017 . The fair value of stock options vested was $16.0 million and $14.0 million during the respective nine months ended September 29, 2018 , and September 30, 2017 . As of September 29, 2018 , there was $22.1 million of unrecognized compensation cost related to non-vested stock options that is expected to be recognized as a charge to earnings over a weighted-average period of 1.7 years . Performance Awards Performance awards, which are granted as performance share units (“PSUs”) and performance-based RSUs, are earned and expensed using the fair value of the award over a contractual term of three years based on the company’s performance. Vesting of the performance awards is dependent upon performance relative to pre-defined goals for revenue growth and return on net assets for the applicable performance period. For performance achieved above specified levels, the recipient may earn additional shares of stock, not to exceed 100% of the number of performance awards initially granted. The PSUs have a three -year performance period based on the results of the consolidated financial metrics of the company. The performance-based RSUs have a one -year performance period based on the results of the consolidated financial metrics of the company followed by a two -year cliff vesting schedule, assuming continued employment. The fair value of performance awards is calculated using the market value of a share of Snap-on’s common stock on the date of grant and assumed forfeitures based on recent historical experience; in recent years, forfeitures have not been significant. The weighted-average grant date fair value of performance awards granted during the nine months ended September 29, 2018 , and September 30, 2017 , was $161.18 and $168.70 , respectively. PSUs related to 50,182 shares and 60,980 shares were paid out during the respective nine months ended September 29, 2018 , and September 30, 2017 . Earned PSUs are generally paid out following the conclusion of the applicable performance period upon approval by the Organization and Executive Compensation Committee of the company’s Board of Directors (the “Board”). Based on the company’s 2017 performance, 13,648 RSUs granted in 2017 were earned; assuming continued employment, these RSUs will vest at the end of fiscal 2019 . Based on the company’s 2016 performance, 45,502 RSUs granted in 2016 were earned; assuming continued employment, these RSUs will vest at the end of fiscal 2018 . Based on the company’s 2015 performance, 64,327 RSUs granted in 2015 were earned; these RSUs vested as of fiscal 2017 year end and were paid out shortly thereafter. Changes to the company’s non-vested performance awards during the nine months ended September 29, 2018 , are as follows: Shares (in thousands) Fair Value Price per Share* Non-vested performance awards at December 30, 2017 132 $ 149.93 Granted 87 161.18 Vested — — Cancellations and other (15 ) 160.21 Non-vested performance awards at September 29, 2018 204 153.99 * Weighted-average As of September 29, 2018 , there was $13.5 million of unrecognized compensation cost related to non-vested performance awards that is expected to be recognized as a charge to earnings over a weighted-average period of 1.9 years . Stock Appreciation Rights (“SARs”) The company also issues stock-settled and cash-settled SARs to certain key non-U.S. employees. SARs have a contractual term of ten years and vest ratably on the first, second and third anniversaries of the date of grant. SARs are granted with an exercise price equal to the market value of a share of Snap-on’s common stock on the date of grant. Stock-settled SARs are accounted for as equity instruments and provide for the issuance of Snap-on common stock equal to the amount by which the company’s stock has appreciated over the exercise price. Stock-settled SARs have an effect on dilutive shares and shares outstanding as any appreciation of Snap-on’s common stock value over the exercise price will be settled in shares of common stock. Cash-settled SARs provide for the cash payment of the excess of the fair market value of Snap-on’s common stock price on the date of exercise over the grant price. Cash-settled SARs have no effect on dilutive shares or shares outstanding as any appreciation of Snap-on’s common stock over the grant price is paid in cash and not in common stock. The fair value of stock-settled SARs is estimated on the date of grant using the Black-Scholes valuation model. The fair value of cash-settled SARs is revalued (mark-to-market) each reporting period using the Black-Scholes valuation model based on Snap-on’s period-end stock price. The company uses historical data regarding SARs exercise and forfeiture behaviors for different participating groups to estimate the expected term of the SARs granted based on the period of time that similar instruments granted are expected to be outstanding. Expected volatility is based on the historical volatility of the company’s stock for the length of time corresponding to the expected term of the SARs. The expected dividend yield is based on the company’s historical dividend payments. The risk-free interest rate is based on the U.S. treasury yield curve in effect as of the grant date (for stock-settled SARs) or reporting date (for cash-settled SARs) for the length of time corresponding to the expected term of the SARs. The following weighted-average assumptions were used in calculating the fair value of stock-settled SARs granted during the nine months ended September 29, 2018 , and September 30, 2017 , using the Black-Scholes valuation model; there were no stock-settled SARs granted during the three months ended September 29, 2018 , or September 30, 2017 : Nine Months Ended September 29, September 30, Expected term of stock-settled SARs (in years) 3.58 3.99 Expected volatility factor 20.08% 19.39% Expected dividend yield 1.63% 1.46% Risk-free interest rate 2.40% 1.55% Changes to the company’s stock-settled SARs during the nine months ended September 29, 2018 , are as follows: Stock-settled SARs (in thousands) Exercise Price Per Share* Remaining Contractual Term* (in years) Aggregate Intrinsic Value (in millions) Outstanding at December 30, 2017 360 $ 138.63 Granted 89 161.18 Exercised (24 ) 105.55 Forfeited or expired (53 ) 129.40 Outstanding at September 29, 2018 372 147.41 7.6 $ 13.5 Exercisable at September 29, 2018 191 135.42 6.6 9.2 * Weighted-average The weighted-average grant date fair value of stock-settled SARs granted during the nine months ended September 29, 2018 , and September 30, 2017 , was $24.71 and $24.13 , respectively. The intrinsic value of stock-settled SARs exercised was $1.2 million and $1.8 million during the respective three and nine months ended September 29, 2018 , and zero and $0.5 million during the respective three and nine months ended September 30, 2017 . The fair value of stock-settled SARs vested was $2.2 million and $2.1 million during the respective nine months ended September 29, 2018 , and September 30, 2017 . As of September 29, 2018 , there was $3.0 million of unrecognized compensation cost related to non-vested stock-settled SARs that is expected to be recognized as a charge to earnings over a weighted-average period of 1.7 years . The following weighted-average assumptions were used in calculating the fair value of cash-settled SARs granted during the nine months ended September 29, 2018 , and September 30, 2017 , using the Black-Scholes valuation model; no cash-settled SARs were granted during the three months ended September 29, 2018 , or September 30, 2017 : Nine Months Ended September 29, September 30, Expected term of cash-settled SARs (in years) 3.01 3.38 Expected volatility factor 21.22% 19.58% Expected dividend yield 1.70% 1.57% Risk-free interest rate 2.88% 1.62% The intrinsic value of cash-settled SARs exercised was $1.1 million and $3.2 million during the respective three and nine months ended September 29, 2018 , and zero and $0.8 million during the respective three and nine months ended September 30, 2017 . The fair value of cash-settled SARs vested was $0.1 million during both the nine months ended September 29, 2018 , and September 30, 2017 . Changes to the company’s non-vested cash-settled SARs during the nine months ended September 29, 2018 , are as follows: Cash-settled SARs (in thousands) Fair Value Price per Share* Non-vested cash-settled SARs at December 30, 2017 5 $ 35.41 Granted 1 39.15 Vested (3 ) 42.69 Non-vested cash-settled SARs at September 29, 2018 3 40.19 * Weighted-average As of September 29, 2018 , there was $0.1 million of unrecognized compensation cost related to non-vested cash-settled SARs that is expected to be recognized as a charge to earnings over a weighted-average period of 1.4 years . Restricted Stock Awards – Non-employee Directors The company awarded 6,975 shares and 6,966 shares of restricted stock to non-employee directors in the first nine months of 2018 and 2017 , respectively. The fair value of the restricted stock awards is expensed over a one -year vesting period based on the fair value on the date of grant. All restrictions for the restricted stock generally lapse upon the earlier of the first anniversary of the grant date, the recipient’s death or disability or in the event of a change in control, as defined in the 2011 Plan. If termination of the recipient’s service occurs prior to the first anniversary of the grant date for any reason other than death or disability, the shares of restricted stock would be forfeited, unless otherwise determined by the Board.

Financial Services consists of the business operations of Snap-on’s finance subsidiaries. Snap-on evaluates the performance of its operating segments based on segment revenues, including both external and intersegment net sales, and segment operating earnings. Snap-on accounts for intersegment sales and transfers based primarily on standard costs with reasonable mark-ups established between the segments. Identifiable assets by segment are those assets used in the respective reportable segment’s operations.

Each of the company’s 2018 and 2017 fiscal first , second and third quarters contained 13 weeks of operating results. Certain prior year amounts have been reclassified on the Condensed Consolidated Statements of Earnings to conform to the 2018 presentation following the retrospective adoption of ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . The effects of the adjustments to the Condensed Consolidated Statements of Earnings as a result of the adoption of ASU No. 2017-07 for the three and nine month periods ended September 30, 2017 , are as follows: For the three months ended September 30, 2017 For the nine months ended September 30, 2017 As Adjusted As Adjusted Previously for ASU As Previously for ASU As (Amounts in millions) Reported No. 2017-07 Adjusted Reported No. 2017-07 Adjusted Net sales $ 903.8 $ — $ 903.8 $ 2,712.3 $ — $ 2,712.3 Cost of goods sold (455.2 ) 0.2 (455.0 ) (1,352.7 ) 0.7 (1,352.0 ) Gross profit 448.6 0.2 448.8 1,359.6 0.7 1,360.3 Operating expenses (295.5 ) (0.6 ) (296.1 ) (853.3 ) (0.4 ) (853.7 ) Operating earnings before financial services 153.1 (0.4 ) 152.7 506.3 0.3 506.6 Operating earnings from financial services 56.0 — 56.0 163.1 — 163.1 Operating earnings 209.1 (0.4 ) 208.7 669.4 0.3 669.7 Interest expense (13.1 ) — (13.1 ) (38.8 ) — (38.8 ) Other income (expense) - net (2.1 ) 0.4 (1.7 ) (5.7 ) (0.3 ) (6.0 ) Earnings before income taxes and equity earnings $ 193.9 $ — $ 193.9 $ 624.9 $ — $ 624.9 Furthermore, the effects of the adjustments to the Consolidated Statements of Earnings as a result of the adoption of ASU No. 2017-07 for the fiscal years ended December 30, 2017, and December 31, 2016, are as follows: 2017 2016 As Adjusted As Adjusted Previously for ASU As Previously for ASU As (Amounts in millions) Reported No. 2017-07 Adjusted Reported No. 2017-07 Adjusted Net sales $ 3,686.9 $ — $ 3,686.9 $ 3,430.4 $ — $ 3,430.4 Cost of goods sold (1,862.0 ) 1.0 (1,861.0 ) (1,720.8 ) 0.8 (1,720.0 ) Gross profit 1,824.9 1.0 1,825.9 1,709.6 0.8 1,710.4 Operating expenses (1,160.9 ) (0.4 ) (1,161.3 ) (1,054.1 ) 6.1 (1,048.0 ) Operating earnings before financial services 664.0 0.6 664.6 655.5 6.9 662.4 Operating earnings from financial services 217.5 — 217.5 198.7 — 198.7 Operating earnings 881.5 0.6 882.1 854.2 6.9 861.1 Interest expense (52.4 ) — (52.4 ) (52.2 ) — (52.2 ) Other income (expense) - net (7.2 ) (0.6 ) (7.8 ) (0.6 ) (6.9 ) (7.5 ) Earnings before income taxes and equity earnings $ 821.9 $ — $ 821.9 $ 801.4 $ — $ 801.4 Additionally, prior year “Operating earnings” for certain reportable business segments have been adjusted to reflect these reclassifications. See Note 17 for information on Snap-on’s reportable business segments. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for the fair presentation of the Condensed Consolidated Financial Statements for the three and nine month periods ended September 29, 2018 , and September 30, 2017 , have been made. Interim results of operations are not necessarily indicative of the results to be expected for the full fiscal year.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Financial Instruments	Financial Instruments The fair value of the company’s derivative financial instruments is generally determined using quoted prices in active markets for similar assets and liabilities. The carrying value of the company’s non-derivative financial instruments either approximates fair value, due to their short-term nature, or the amount disclosed for fair value is based upon a discounted cash flow analysis or quoted market values. See Note 9 for further information on financial instruments.
Change in Functional Currency	Change in Functional Currency Argentina’s economy has been determined to be highly inflationary effective July 1, 2018. As a result, for GAAP reporting, the functional currency for the company’s subsidiary in Argentina changed from the Argentinian Peso to the U.S. Dollar. The impact of the change in functional currency was not material to the Condensed Consolidated Financial Statements for the three and nine months ended September 29, 2018.
New Accounting Standards	New Accounting Standards The following new accounting pronouncements were adopted in fiscal year 2018 : In March 2017, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2017-07, which provides additional guidance on the presentation of net periodic pension and postretirement benefit costs in the income statement and on the components eligible for capitalization. The amendments in this ASU require that an employer report the service cost component of the net periodic benefit costs in the same income statement line item as other compensation costs arising from services rendered by employees during the period. The non-service-cost components of net periodic benefit costs are to be presented in the income statement separately from the service cost components and outside a subtotal of income from operations. The ASU also allows for the capitalization of the service cost components, when applicable (i.e., as a cost of internally manufactured inventory or a self-constructed asset). Snap-on adopted this ASU at the beginning of its 2018 fiscal year, with the changes related to the presentation in the statements of earnings of the service cost and non-service-cost components of net periodic benefit costs applied retrospectively, using the practical expedient permitting the use of the amounts disclosed in pension and other postretirement benefit plan notes as the estimation basis for the presentation of the prior comparative periods. For fiscal 2018 and all comparative periods, the non-service-cost components of net periodic benefit costs are included in “Other income (expense) - net” on the accompanying condensed consolidated statements of earnings. Beginning in fiscal 2018, changes related to the capitalization in assets of the service cost component of net periodic benefit costs were applied prospectively. The adoption of this ASU did not have a significant impact on the company’s Condensed Consolidated Statements of Earnings. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740) – Intra-Entity Transfers of Assets Other Than Inventory . The ASU eliminates the requirement to defer the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party. Under the new guidance, an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this ASU were to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings at the time of adoption. The adoption of this ASU did not have an impact on the company’s consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) , which adds and/or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The new guidance is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this ASU did not have a significant impact to the designations of operating, investing and financing activities on the company’s Condensed Consolidated Statements of Cash Flows. On December 31, 2017, the beginning of Snap-on’s 2018 fiscal year, Snap-on adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. Topic 606 is based on the principle that an entity should recognize revenue to depict the transfer of 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. Topic 606 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Snap-on adopted Topic 606 using the modified retrospective approach applied to those contracts that were not completed as of December 31, 2017, which means Topic 606 has been applied to the fiscal 2018 financial statements and disclosures going forward, but that prior period financial statements and disclosures reflect the prior revenue recognition standard. See Note 2 for additional information on revenue recognition. Snap-on’s revenues are primarily from the selling of products that are shipped and billed, services provided to customers and from subscriptions, including software subscriptions. Approximately 90% of net sales are earned at a point in time through ship-and- bill performance obligations. The remaining performance obligations that are recorded over time relate primarily to software subscriptions and to a lesser extent extended warranty and other subscription agreements. Revenues are recognized when control is transferred to customers, in an amount that reflects the consideration Snap-on expects to be entitled to in exchange for those goods and services. Revenue recognition is evaluated through the following five steps: (i) identification of the contract, or contracts, with a customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when or as a performance obligation is satisfied. Revenue related to software subscriptions, as well as extended warranty and other subscription agreements, is generally recognized over time on a ratable basis over the contract term beginning on the date that our service is made available to the customer. Contracts with customers may include multiple performance obligations related to sales of hardware, software and software-related services. For these contracts, individual performance obligations are recorded separately if they are distinct. The transaction price, including any discounts, is allocated to each separate performance obligation based on its relative standalone selling price. The standalone selling prices are determined based on the prices charged to customers or by using an expected cost plus margin approach. The amount assigned to the products or services is recognized when the product is delivered and/or when the services are performed. In instances where the product and/or services are performed over an extended period, as is the case with subscription agreements, revenue is generally recognized over time on a ratable basis using a time-based output method applied over the contract term beginning on the date that the service is made available to the customer. These contracts are generally for 12 months but can be for a term up to 60 months . Franchise fee revenue, including nominal, non-refundable initial fees, is recognized upon the granting of a franchise, which is when the company has performed substantially all initial services required by the franchise agreement. Franchise fee revenue also includes ongoing monthly fees (primarily for sales and business training as well as marketing and product promotion programs) that are recognized as the fees are earned. Franchise fee revenue totaled $ 3.9 million and $ 12.0 million for the three and nine month periods ended September 29, 2018 , respectively. The following new accounting pronouncements, and related impacts on adoption, are being evaluated by the company: In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement , which is designed to improve the effectiveness of disclosures by removing, modifying and adding disclosures related to fair value measurements. ASU No. 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years; the ASU allows for early adoption in any interim period after issuance of the update. The company is currently assessing the impact this ASU will have on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General Subtopic 715-20 - Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans, which is designed to improve the effectiveness of disclosures by removing and adding disclosures related to defined benefit plans. ASU No. 2018-14 is effective for fiscal years ending after December 15, 2020; the ASU allows for early adoption in any year end after issuance of the update. The company is currently assessing the impact this ASU will have on its consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220) , which allows for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from “H.R.1”, formerly known as the Tax Cuts and Jobs Act (the “Tax Act”). ASU No. 2018-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years; the ASU allows for early adoption in any interim period after issuance of the update. The adoption of this ASU is not expected to have a significant impact on the company’s consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities , which improves the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments in this update also make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. ASU No. 2017-12 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years; the ASU allows for early adoption in any interim period after issuance of the update. The adoption of this ASU is not expected to have a significant impact on the company’s consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) , to require the measurement of expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable forecasts. The main objective of this ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. ASU No. 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years; the ASU allows for early adoption as of the beginning of an interim or annual reporting period beginning after December 15, 2018. The company is currently assessing the impact this ASU will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The ASU is intended to represent an improvement over previous GAAP, which did not require lease assets and lease liabilities to be recognized for most leases. This ASU, which supersedes most current lease guidance, affects any entity that enters into a lease (as that term is defined in the ASU), with some specified scope exemptions. ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years; the ASU allows for early adoption as of the beginning of an interim or annual reporting period. Snap-on commenced its assessment of Topic 842 during the second half of 2017 and developed a comprehensive project plan that included representatives from across the company’s business segments. The project plan included evaluating Snap-on’s lease portfolio, analyzing the standard’s impact on the company’s various types of lease contracts and identifying the reporting requirements of the new standard. The company is in the process of identifying and implementing appropriate changes to its business processes, systems and controls to support lease accounting and disclosures under Topic 842. As of September 29, 2018, and subject to the company’s ongoing evaluation of new lease contracts, the company has made further progress with its evaluation of the expected impact of adopting Topic 842 and anticipates that the adoption of this standard will not have a significant impact on the company’s consolidated financial statements. As a result of the adoption of this standard, a right-of-use asset and a related lease liability will be established to reflect the present value of the future lease payments at a level comparable to those reported in Snap-on’s 2017 Annual Report on Form 10-K.
