Accounting Policies [Abstract]
Summary of Accounting Policies	Note 1: Summary of Accounting Policies Principles of consolidation and presentation: Snap-on “Snap-on” Snap-on Snap-on Snap-on’s Fiscal year accounting period: Snap-on’s Use of estimates: Financial instruments: non-derivative Revenue recognition: Snap-on Snap-on Snap-on Franchise fee revenue, including nominal, non-refundable Financial services revenue: Snap-on Snap-on Snap-on’s The decision to finance through Snap-on Snap-on Snap-on Snap-on Financial services lease arrangements: Snap-on Snap-on, Snap-on’s Research and engineering: Snap-on Internally developed software: Snap-on Internal-use Shipping and handling: Snap-on Snap-on Advertising and promotion: Warranties: Snap-on Foreign currency: Snap-on’s Income taxes: Snap-on more-likely-than-not Snap-on more-likely-than-not Deferred income taxes are provided for temporary differences arising from differences in bases of assets and liabilities for tax and financial reporting purposes. Deferred income taxes are recorded on temporary differences using enacted tax rates in effect for the year in which the temporary differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more-likely-than-not Per share data: Snap-on Snap-on Stock-based compensation: Snap-on The Black-Scholes valuation model requires the input of subjective assumptions, including the expected life of the stock-based award and stock price volatility. The assumptions used are management’s best estimates, but the estimates involve inherent uncertainties and the application of management judgment. As a result, if other assumptions had been used, the recorded stock-based compensation expense could have been materially different from that depicted in the financial statements. See Note 13 for further information on stock-based compensation. Derivatives: Snap-on Snap-on Snap-on Cash equivalents: Snap-on Receivables and allowances for doubtful accounts: Snap-on Snap-on • Snap-on Snap-on • For finance and contract receivables, Snap-on • Collection experience – Snap-on non-performing charge-off • Other internal metrics – Snap-on Management performs detailed reviews of its receivables on a monthly and/or quarterly basis to assess the adequacy of the allowances based on historical and current trends and other factors affecting credit losses and to determine if any impairment has occurred. 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 agreement. Additions to the allowances for doubtful accounts are maintained through adjustments to the provision for credit losses, which are charged to current period earnings; amounts determined to be uncollectable are charged directly against the allowances, while amounts recovered on previously charged-off charged-off charged-off charged-off charge-off charged-off charged-off charged-off charged-off Snap-on Other accrued liabilities: (Amounts in millions) 2017 2016 Income taxes $ 41.6 $ 21.4 Accrued restructuring 0.6 2.8 Accrued warranty 17.2 16.0 Deferred subscription revenue 38.9 43.0 Accrued property, payroll and other taxes 45.4 36.1 Accrued selling and promotion expense 28.6 24.7 Accrued legal matters 45.9 – Other 169.9 163.9 Total other accrued liabilities $ 388.1 $ 307.9 Inventories: Snap-on Snap-on work-in-progress Snap-on “last-in, first-out” Snap-on’s Snap-on “first-in, first-out” Property and equipment: Goodwill and other intangible assets: Snap-on New accounting standards The following new accounting pronouncement was adopted in fiscal year 2017: In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, Snap-on The following new accounting pronouncements, and related impacts on adoption, are being evaluated by the company: In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities No. 2017-12 In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715) – Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost non-service-cost The ASU is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The company will adopt this ASU at the beginning of its 2018 fiscal year, with the changes applied retrospectively. The adoption of this ASU is not expected to have a significant impact on the company’s consolidated income statement. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740) – Intra-Entity Transfers of Assets Other Than Inventory In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) No. 2016-13 In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) No. 2016-02 In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) Entities have the option of adopting this standard using either a full retrospective approach or a modified retrospective approach (i.e., through a cumulative-effect adjustment directly to retained earnings at the time of adoption). Snap-on As of December 30, 2017, and subject to the company’s ongoing evaluation of new transactions and contracts, the company has substantially completed its evaluation of the expected impact of adopting Topic 606 and anticipates that the adoption of this standard will not have a significant impact on the company’s consolidated financial statements. The company believes that the adoption will result in the recognition of an inventory asset related to certain product returns by increasing the returns liability and inventory for the anticipated value of the returns; the corresponding increase in the inventory asset and returns liability is expected to be approximately $24 million at the date of adoption. The adoption is also expected to result in the recognition of an increase in the inventory obsolescence reserve related to the anticipated value on returns of approximately $3 million and a $1 million increase in deferred income tax assets, with a corresponding adjustment to fiscal 2018 beginning retained earnings. The company will adopt Topic 606 at the beginning of its 2018 fiscal year using the modified retrospective approach.

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.

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 • The fair value of all other 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.

Prior service costs and credits resulting from plan amendments are amortized in equal annual amounts over the average remaining service period of active participants or over the average remaining life expectancy for plans with primarily inactive participants. As a practical expedient, Snap-on Snap-on Snap-on Snap-on The following benefit payments, which reflect expected future service, are expected to be paid as follows: (Amounts in millions) Amount Year: 2018 $ 73.6 2019 75.2 2020 78.9 2021 81.5 2022 91.4 2023-2027 462.3 Snap-on’s Snap-on’s Snap-on Snap-on’s The basis for determining the overall expected long-term return on plan assets assumption is a nominal returns forecasting method. For each asset class, future returns are estimated by identifying the premium of riskier asset classes over lower risk alternatives. The methodology constructs expected returns using a “building block” approach to the individual components of total return. These forecasts are stated in both nominal and real (after inflation) terms. This process first considers the long-term historical return premium based on the longest set of data available for each asset class. These premiums, which are calculated using the geometric mean, are then adjusted based on current relative valuation levels, macro-economic conditions, and the expected alpha related to active investment management. The asset return assumption is also adjusted by an implicit expense load for estimated administrative and investment-related expenses. For risk and correlation assumptions, the actual experience for each asset class is reviewed for the longest time period available. Expected relationships for a 10 to 20 year time horizon are determined based upon historical results, with adjustments made for material changes. Investments are diversified to attempt to minimize the risk of large losses. Since asset allocation is a key determinant of expected investment returns, assets are periodically rebalanced to the targeted allocation to correct significant deviations from the asset allocation policy that are caused by market fluctuations and cash flow. Asset/liability studies are conducted periodically to determine if any revisions to the strategic asset allocation policy are necessary. Snap-on’s Target 2017 2016 Asset category: Equity securities 51% 51% 51% Debt securities and cash and cash equivalents 37% 38% 39% Real estate and other real assets 2% 1% 1% Hedge funds 10% 10% 9% Total 100% 100% 100% Fair value of plan assets (Amounts in millions) $ 1,122.7 $ 957.1 The fair value measurement hierarchy prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority (“Level 1”) to unadjusted quoted prices in active markets for identical assets and liabilities and the lowest priority (“Level 3”) to unobservable inputs. Fair value measurements primarily based on observable market information are given a “Level 2” priority. Certain equity and debt securities are valued at quoted per share or unit market prices for which an official close or last trade pricing on an active exchange is available and are categorized as Level 1 in the fair value hierarchy. If quoted market prices are not readily available for specific securities, values are estimated using quoted prices of securities with similar characteristics and are categorized as Level 2 in the fair value hierarchy. Insurance contracts are valued at the present value of the estimated future cash flows promised under the terms of the insurance contracts and are categorized as Level 2 in the fair value hierarchy. Commingled equity securities and commingled multi-strategy funds are valued at the NAV per share or unit multiplied by the number of shares or units held as of the measurement date, as reported by the fund managers. The share or unit price is quoted on a private market and is based on the value of the underlying investments, which are primarily based on observable inputs; such investments that are measured at fair value using the NAV per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. Private equity partnership funds, hedge funds, and real estate and other real assets are valued at the NAV as reported by the fund managers. Private equity partnership funds, certain hedge funds, and certain real estate and other real assets are valued based on the proportionate interest or share of net assets held by the pension plan, which is based on the estimated fair market value of the underlying investments. Certain other hedge funds and real estate and other real assets are valued at the NAV per share or unit multiplied by the number of shares or units held as of the measurement date, based on the estimated value of the underlying investments as reported by the fund managers. These investments are measured at fair value using the NAV per share (or its equivalent) practical expedient and have not been classified in the fair value hierarchy. The company regularly reviews fund performance directly with its investment advisor and the fund managers, and performs qualitative analysis to corroborate the reasonableness of the reported NAVs. For funds for which the company did not receive a year-end The columns labeled “Investments Measured at NAV” in the following tables reflect certain investments that are measured at fair value using the NAV per share (or its equivalent) practical expedient and have not been categorized in the fair value hierarchy.

Stock-based Compensation and Other Stock Plans	Note 13: Stock-based Compensation and Other Stock Plans The 2011 Incentive Stock and Awards Plan (the “2011 Plan”) provides for the grant of stock options, performance awards, stock appreciation rights (“SARs”) and restricted stock awards (which may be designated as “restricted stock units” or “RSUs”). No further grants are being made under its predecessor, the 2001 Incentive Stock and Awards Plan (the “2001 Plan”), although outstanding awards under the 2001 Plan will continue in accordance with their terms. As of 2017 year end, the 2011 Plan had 3,296,859 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 $30.3 million in 2017, $31.0 million in 2016 and $39.8 million in 2015. Cash received from stock purchase and option plan exercises was $46.2 million in 2017, $41.8 million in 2016 and $41.6 million in 2015. The tax benefit realized from both the exercise and vesting of share-based payment arrangements was $20.9 million in 2017, $24.8 million in 2016 and $26.4 million in 2015. Stock Options Stock options are granted with an exercise price equal to the market value of a share of Snap-on’s 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 2017, 2016 and 2015, using the Black-Scholes valuation model: 2017 2016 2015 Expected term of option (in years) 5.15 5.05 4.76 Expected volatility factor 22.01% 22.17% 24.13% Expected dividend yield 1.63% 1.77% 2.04% Risk-free interest rate 1.78% 1.04% 1.38% A summary of stock option activity during 2017 is presented below: Shares (in thousands) Exercise Remaining (in years) Aggregate (in millions) Outstanding at beginning of year 3,011 $ 100.78 Granted 655 168.71 Exercised (396) 86.29 Forfeited or expired (72) 153.53 Outstanding at end of year 3,198 115.30 6.4 $ 188.7 Exercisable at end of year 1,990 91.27 5.1 165.2 * Weighted-average The weighted-average grant date fair value of options granted was $31.13 in 2017, $22.99 in 2016 and $25.64 in 2015. The intrinsic value of options exercised was $33.3 million in 2017, $35.2 million in 2016 and $37.6 million in 2015. The fair value of stock options vested was $14.0 million in 2017, $12.7 million in 2016 and $9.9 million in 2015. As of 2017 year end, there was $19.3 million of unrecognized compensation cost related to non-vested 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 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 two-year The fair value of performance awards is calculated using the market value of a share of Snap-on’s 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.

New accounting standards	New accounting standards The following new accounting pronouncement was adopted in fiscal year 2017: In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, Snap-on The following new accounting pronouncements, and related impacts on adoption, are being evaluated by the company: In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities No. 2017-12 In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715) – Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost non-service-cost The ASU is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The company will adopt this ASU at the beginning of its 2018 fiscal year, with the changes applied retrospectively. The adoption of this ASU is not expected to have a significant impact on the company’s consolidated income statement. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740) – Intra-Entity Transfers of Assets Other Than Inventory In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) No. 2016-13 In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) No. 2016-02 In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) Entities have the option of adopting this standard using either a full retrospective approach or a modified retrospective approach (i.e., through a cumulative-effect adjustment directly to retained earnings at the time of adoption). Snap-on As of December 30, 2017, and subject to the company’s ongoing evaluation of new transactions and contracts, the company has substantially completed its evaluation of the expected impact of adopting Topic 606 and anticipates that the adoption of this standard will not have a significant impact on the company’s consolidated financial statements. The company believes that the adoption will result in the recognition of an inventory asset related to certain product returns by increasing the returns liability and inventory for the anticipated value of the returns; the corresponding increase in the inventory asset and returns liability is expected to be approximately $24 million at the date of adoption. The adoption is also expected to result in the recognition of an increase in the inventory obsolescence reserve related to the anticipated value on returns of approximately $3 million and a $1 million increase in deferred income tax assets, with a corresponding adjustment to fiscal 2018 beginning retained earnings. The company will adopt Topic 606 at the beginning of its 2018 fiscal year using the modified retrospective approach.
