Notes To Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (hereinafter referred to as “generally accepted accounting principles”) for interim financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X and do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation of the results of operations for the interim periods have been included and are of a normal, recurring nature. Operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for a full fiscal year. For further information, refer to the consolidated financial statements and footnotes included in Stanley Black & Decker, Inc.’s (the “Company”) Form 10-K for the year ended December 31, 2016 , and subsequent related filings with the Securities and Exchange Commission. In February 2017, the Company sold the majority of its mechanical security businesses within the Security segment, which included the commercial hardware brands of Best Access, phi Precision and GMT. In addition, the Company sold a small business within the Tools & Storage segment on January 3, 2017 and a small business within the Industrial segment on September 2, 2017. The operating results of these businesses have been reported within continuing operations in the Condensed Consolidated Financial Statements through their respective dates of sale in 2017 and for the three and nine months ended October 1, 2016 . In addition, the assets and liabilities related to the businesses sold in the first quarter of 2017 were classified as held for sale on the Company's Condensed Consolidated Balance Sheets as of December 31, 2016. Refer to Note T, Divestitures, for further discussion. In March 2017, the Company acquired the Tools business of Newell Brands ("Newell Tools") and the Craftsman brand, which are both being accounted for as business combinations. The results of these acquisitions are being consolidated into the Company's Tools & Storage segment. Refer to Note F, Acquisitions, for further discussion. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements. While management believes that the estimates and assumptions used in the preparation of the financial statements are appropriate, actual results could differ from these estimates.

New Accounting Standards

New Accounting Standards	9 Months Ended
	Sep. 30, 2017
Notes To Financial Statements [Abstract]
New Accounting Standards	New Accounting Standards In August 2017, the Financial Accounting Standards Boards ("FASB") issued Accounting Standards Update ("ASU") 2017-12, Derivatives and Hedging (Topic 815) . The new standard amends the hedge accounting recognition and presentation requirements in ASC 815. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the timing of adopting the new guidance as well as the impact it may have on its consolidated financial statements. In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715). The new standard improves the presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, and should be applied retrospectively. Based on the Company's preliminary assessment, the anticipated impacts to the consolidated financial statements relate to classification of the components of net pension and postretirement benefit costs on the income statement. In February 2017, the FASB issued ASU 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610). The new standard provides guidance for recognizing gains and losses of nonfinancial assets in contracts with non-customers. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company will adopt this guidance in the first quarter of 2018 and does not expect it to have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new standard simplifies the subsequent measurement of goodwill by eliminating the second step of the goodwill impairment test. This ASU will be applied prospectively and is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The new standard narrows the definition of a business and provides a framework for evaluation. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . The new standard eliminates the exception to the principle in ASC 740, for all intra-entity sales of assets other than inventory, to be deferred, until the transferred asset is sold to a third party or otherwise recovered through use. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company will adopt this guidance in the first quarter of 2018 and does not expect it to have a material impact on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) . The objective of this update is to provide additional guidance and reduce diversity in practice when classifying certain transactions within the statement of cash flows. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash . The new standard requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. These standards are effective for financial statements issued for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326). The new standard amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . The objective of this update is to simplify several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU was effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company adopted this standard prospectively in the first quarter of 2017 and it did not have a material impact on its consolidated financial statements. Prior periods were not adjusted. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . The objective of this update is 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. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods and is to be applied utilizing a modified retrospective approach. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities . The main objective of this update is to enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information. The new guidance addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company has evaluated the new guidance and expects it will not have a material impact on its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This ASU changes the measurement principle for certain inventory methods from the lower of cost or market to the lower of cost and net realizable value. Net realizable value is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This ASU does not apply to inventory that is measured using the Last-in First-out ("LIFO") or the retail inventory method. The provisions of ASU 2015-11 were effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company adopted this standard in the first quarter of 2017 and it did not have an impact on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The new revenue recognition standard outlines a comprehensive model for companies to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. The new model provides a five-step analysis in determining when and how revenue is recognized. The core principle of the new guidance is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB affirmed its proposal to defer the effective date of the standard to annual reporting periods (and interim reporting periods within those years) beginning after December 15, 2017. Entities are permitted to apply the new revenue standard early, but not before the original effective date of annual periods beginning after December 15, 2016. The standard shall be applied retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. In March, April, May and December 2016, the FASB clarified the implementation guidance on principal versus agent, identifying performance obligations, licensing, collectability and made technical corrections on various topics. The Company expects to apply the full retrospective method of adoption starting with the first interim period after December 15, 2017. Based on the Company’s assessment, the anticipated impacts to the financial statements are primarily related to classification of outbound freight on the income statement and presentation of sales returns reserve.

On and after May 15, 2020, the convertible preferred stock may be converted into common stock at the option of the holder. At the election of the Company, upon conversion, the Company may deliver cash, common stock, or a combination thereof. The conversion rate was initially 6.1627 shares of common stock per one share of convertible preferred stock, which is equivalent to an initial conversion price of approximately $162.27 per share of common stock. As of September 30, 2017, due to the customary anti-dilution provisions, the conversion rate was 6.1649 , equivalent to a conversion price of approximately $162.21 per share of common stock. The convertible preferred stock is excluded from the denominator of the diluted earnings per share calculation on the basis that the convertible preferred stock will be settled in cash except to the extent that the conversion value of the convertible preferred stock exceeds its liquidation preference. Therefore, before any redemption or conversion, the common shares that would be required to settle the applicable conversion value in excess of the liquidation preference, if the Company elects to settle such excess in common shares, would be included in the denominator of diluted earnings per share. As described in detail in Note J, Equity Arrangements, the Company issued Equity Units in December 2013 comprised of $345.0 million of Notes and Equity Purchase Contracts, which obligated the holders to purchase on November 17, 2016, for $100 , between 1.0122 and 1.2399 shares of the Company’s common stock. The shares related to the Equity Purchase Contracts were anti-dilutive during January and February 2016. Upon the November 17, 2016 settlement date, the Company issued 3,504,165 shares of common stock and received cash proceeds of $345.0 million .

Financing Receivables

Financing Receivables	9 Months Ended
	Sep. 30, 2017
Notes To Financial Statements [Abstract]
Financing Receivables	Financing Receivables Long-term trade financing receivables of $191.1 million and $180.9 million at September 30, 2017 and December 31, 2016 , respectively, are reported within Other Assets in the Condensed Consolidated Balance Sheets. Financing receivables and long-term financing receivables are predominantly related to certain security equipment leases with commercial businesses. Generally, the Company retains legal title to any equipment under lease and bears the right to repossess such equipment in an event of default. All financing receivables are interest bearing and the Company has not classified any financing receivables as held-for-sale. Interest income earned from financing receivables that are not delinquent is recorded on the effective interest method. The Company considers any financing receivable that has not been collected within 90 days of original billing date as past-due or delinquent. Additionally, the Company considers the credit quality of all past-due or delinquent financing receivables as non-performing. The Company has an accounts receivable sale program that expires on January 5, 2018. According to the terms of that program, the Company is required to sell certain of its trade accounts receivables at fair value to a wholly-owned, consolidated, bankruptcy-remote special purpose subsidiary (“BRS”). The BRS, in turn, must sell such receivables to a third-party financial institution (“Purchaser”) for cash and a deferred purchase price receivable. The Purchaser’s maximum cash investment in the receivables at any time is $100.0 million . The purpose of the program is to provide liquidity to the Company. The Company accounts for these transfers as sales under ASC 860, "Transfers and Servicing." Receivables are derecognized from the Company’s consolidated balance sheet when the BRS sells those receivables to the Purchaser. The Company has no retained interests in the transferred receivables, other than collection and administrative responsibilities and its right to the deferred purchase price receivable. At September 30, 2017 , the Company did not record a servicing asset or liability related to its retained responsibility based on its assessment of the servicing fee, market values for similar transactions and its cost of servicing the receivables sold. At September 30, 2017 and December 31, 2016 , $61.0 million and $100.5 million , respectively, of net receivables were derecognized. Gross receivables sold amounted to $546.1 million ( $460.0 million , net) and $1,549.3 million ( $1,312.9 million , net) for the three and nine months ended September 30, 2017 , respectively. These sales resulted in a pre-tax loss of $2.0 million and $5.3 million , respectively, and included servicing fees of $0.4 million and $1.0 million , respectively, for the three and nine months ended September 30, 2017 . Proceeds from transfers of receivables to the Purchaser totaled $432.1 million and $1,213.0 million for the three and nine months ended September 30, 2017 , respectively. Collections of previously sold receivables, including deferred purchase price receivables, and all fees, which are settled one month in arrears, resulted in payments to the Purchaser of $471.9 million and $1,252.9 million for the three and nine months ended September 30, 2017 , respectively. Gross receivables sold amounted to $433.6 million ( $364.8 million , net) and $1,307.1 million ( $1,111.0 million , net) for the three and nine months ended October 1, 2016 , respectively. These sales resulted in a pre-tax loss of $1.1 million and $3.5 million , respectively, and included servicing fees of $0.2 million and $0.6 million , respectively, for the three and nine months ended October 1, 2016 . Proceeds from transfers of receivables to the Purchaser totaled $354.0 million and $1,031.6 million , respectively, for the three and nine months ended October 1, 2016 . Collections of previously sold receivables, including deferred purchase price receivables, and all fees, which are settled one month in arrears, resulted in payments to the Purchaser of $375.5 million and $1,053.1 million , respectively, for the three and nine months ended October 1, 2016 . The Company’s risk of loss following the sale of the receivables is limited to the deferred purchase price receivable, which was $202.0 million at September 30, 2017 and $83.2 million at December 31, 2016 . The deferred purchase price receivable will be repaid in cash as receivables are collected, generally within 30 days, and as such the carrying value of the receivable recorded approximates fair value. There were $0.1 million of delinquencies or credit losses for the three and nine months ended September 30, 2017 and October 1, 2016 . Cash inflows related to the deferred purchase price receivable totaled $216.4 million and $504.8 million for the three and nine months ended September 30, 2017 , respectively, and $135.2 million and $354.7 million for the three and nine months ended October 1, 2016 , respectively. All cash flows under the program are reported as a component of changes in working capital within operating activities in the Condensed Consolidated Statements of Cash Flows since all the cash from the Purchaser is either: 1) received upon the initial sale of the receivable or 2) from the ultimate collection of the underlying receivables and the underlying receivables are not subject to significant risks, other than credit risk, given their short-term nature.

Acquisitions	Acquisitions 2017 ACQUISITIONS Newell Tools On March 9, 2017, the Company acquired the Tools business of Newell Brands ("Newell Tools"), which includes the industrial cutting, hand tool and power tool accessory brands Irwin® and Lenox®, for approximately $1.84 billion , net of cash acquired and an estimated working capital adjustment. This acquisition enhances the Company’s position within the global tools & storage industry and broadens the Company’s product offerings and solutions to customers and end users, particularly within power tool accessories. The results of Newell Tools are being consolidated into the Company's Tools & Storage segment. The Newell Tools acquisition is being accounted for as a business combination, which requires, among other things, the assets acquired and liabilities assumed to be recognized at their fair values as of the acquisition date. The following table summarizes the estimated fair values of major assets acquired and liabilities assumed: (Millions of Dollars) Cash and cash equivalents $ 20.0 Accounts and notes receivable, net 26.9 Inventories, net 198.2 Prepaid expenses and other current assets 22.1 Property, plant and equipment, net 118.7 Trade names 283.0 Customer relationships 548.0 Other assets 8.2 Accounts payable (70.2 ) Accrued expenses (37.5 ) Deferred taxes (307.9 ) Other liabilities (3.1 ) Total identifiable net assets $ 806.4 Goodwill 1,051.0 Total consideration paid $ 1,857.4 The trade names were determined to have indefinite lives. The weighted-average useful life assigned to the customer relationships is 15 years . Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the expected revenue and cost synergies of the combined business, assembled workforce, and the going concern nature of Newell Tools. It is estimated that $14.9 million of goodwill, relating to the pre-acquisition historical tax basis of goodwill, will be deductible for tax purposes. The purchase price allocation for Newell Tools is preliminary in certain respects. During the measurement period, the Company expects to record adjustments relating to the finalization of inventory and property, plant and equipment valuations, various opening balance sheet contingencies, including environmental remediation and risk insurance reserves, and various income tax matters, amongst others. A single estimate of fair value results from a complex series of judgments about future events and uncertainties and relies heavily on estimates and assumptions. The Company’s judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company’s results from operations. The Company will complete its purchase price allocation as soon as reasonably possible within the measurement period. Craftsman Brand On March 8, 2017, the Company purchased the Craftsman brand from Sears Holdings, which provides the Company with the rights to develop, manufacture and sell Craftsman®-branded products in non-Sears Holdings channels. The total estimated cash purchase price is $887.4 million , consisting of an initial cash payment of $569.4 million , which reflects the impact of working capital adjustments, a cash payment at the end of year three with an estimated present value of $234.0 million , and future payments to Sears Holdings of between 2.5% and 3.5% on sales of Craftsman products in new Stanley Black & Decker channels through March 2032, which was initially valued at $84.0 million at the acquisition date based on estimated future sales projections which are subject to change. Refer to Note M, Fair Value Measurements, for additional details. In addition, as part of the acquisition the Company also granted a perpetual license to Sears Holdings to continue selling Craftsman®-branded products in Sears-related channels. The perpetual license will be royalty-free until March 2032, which represents an estimated value of approximately $293.0 million , and 3% thereafter. The Craftsman results are being consolidated into the Company's Tools & Storage segment. The Craftsman brand acquisition is being accounted for as a business combination which requires, among other things, the assets acquired and liabilities assumed to be recognized at their fair values as of the acquisition date. The estimated fair value of identifiable assets acquired, which includes $45.2 million of working capital and $433.0 million of intangible assets, is $589.8 million . The related goodwill is $590.6 million . The amount allocated to intangible assets includes $406.0 million of an indefinite-lived trade name. The useful life assigned to the customer relationships is 15 years . Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the expected revenue and cost synergies of the combined business and the going concern nature of the Craftsman brand. A portion of the goodwill is expected to be deductible for tax purposes. The purchase price allocation for Craftsman is preliminary in certain respects. During the measurement period, the Company expects to record adjustments relating to the finalization of valuations for intangible assets, the contingent consideration liability relating to future payments to Sears Holdings, and various opening balance sheet contingencies, including warranty exposures, amongst others. A single estimate of fair value results from a complex series of judgments about future events and uncertainties and relies heavily on estimates and assumptions. The Company’s judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company’s results from operations. The Company will complete its purchase price allocation as soon as reasonably possible within the measurement period. OTHER ACQUISITIONS The Company completed an acquisition during the first quarter of 2017 for a total purchase price of $26.1 million , net of cash acquired, which is being consolidated into the Company's Security segment. During the third quarter of 2017, the Company completed three acquisitions for a total purchase price of $152.0 million , net of cash acquired, which are being consolidated into the Company's Tools & Storage and Security segments. During the measurement period, the Company expects to record adjustments relating to the finalization of valuations for intangible assets, working capital accounts, and various opening balance sheet contingencies. 2016 ACQUISITIONS During 2016, the Company completed five acquisitions for a total purchase price of $59.3 million , net of cash acquired, which have been consolidated into the Company’s Tools & Storage and Security segments. The total purchase price for the acquisitions was allocated to the assets acquired and liabilities assumed based on their estimated fair values. The purchase accounting for these acquisitions is complete. ACTUAL AND PRO-FORMA IMPACT OF THE ACQUISTIONS Actual Impact from Acquisitions The net sales and net earnings (loss) from 2017 acquisitions included in the Company's Consolidated Statements of Operations and Comprehensive Income for the three and nine months ended September 30, 2017 are shown in the table below. These amounts include amortization relating to inventory step-up and intangible assets recorded upon acquisition, transaction costs, and other integration-related costs. (Millions of Dollars) Third Quarter 2017 Year-to-Date 2017 Net sales $ 252.5 $ 532.9 Net earnings (loss) attributable to common shareowners $ 3.6 $ (39.3 ) Pro-forma Impact from Acquisitions The following table presents supplemental pro-forma information as if the 2017 acquisitions had occurred on January 3, 2016. The pro-forma consolidated results are not necessarily indicative of what the Company’s consolidated net sales and net earnings would have been had the Company completed the acquisitions on January 3, 2016. In addition, the pro-forma consolidated results do not purport to project the future results of the Company. Third Quarter Year-to-Date (Millions of Dollars, except per share amounts) 2017 2016 2017 2016 Net sales $ 3,309.3 $ 3,119.2 $ 9,570.1 $ 9,198.3 Net earnings attributable to common shareowners 292.2 251.8 1,044.8 667.5 Diluted earnings per share $ 1.91 $ 1.70 $ 6.87 $ 4.52 2017 Pro-forma Results The 2017 pro-forma results were calculated by combining the results of Stanley Black & Decker with the stand-alone results of the 2017 acquisitions for their respective pre-acquisition periods. Accordingly the following adjustments were made: • Elimination of the historical pre-acquisition intangible asset amortization expense and the addition of intangible asset amortization expense related to intangibles valued as part of the purchase price allocation that would have been incurred from January 1, 2017 to the acquisition dates. • Additional depreciation expense for the property, plant, and equipment fair value adjustments that would have been incurred from January 1, 2017 to the acquisition date of Newell Tools. • Because the 2017 acquisitions were assumed to occur on January 3, 2016, there were no deal costs or inventory step-up amortization factored into the 2017 pro-forma year, as such expenses would have occurred in the first year following the acquisition. 2016 Pro-forma Results The 2016 pro-forma results were calculated by taking the historical financial results of Stanley Black & Decker and adding the historical results of the 2017 acquisitions for their respective pre-acquisition periods. Accordingly the following adjustments were made assuming the acquisitions commenced on January 3, 2016: • Elimination of the historical pre-acquisition intangible asset amortization expense and the addition of intangible asset amortization expense related to intangibles valued as part of the purchase price allocation that would have been incurred for the three and nine months ended October 1, 2016 . • Additional expense for deal costs and inventory step-up, which would have been amortized as the corresponding inventory was sold. • Additional depreciation expense for the property, plant, and equipment fair value adjustments that would have been incurred for the three and nine months ended October 1, 2016 for Newell Tools.

In January 2017, the Company amended its existing $2.0 billion commercial paper program to increase the maximum amount of notes authorized to be issued to $3.0 billion and to include Euro denominated borrowings in addition to U.S. Dollars. As of September 30, 2017 , the Company had $573.1 million of borrowings outstanding against the Company’s $3.0 billion commercial paper program, of which approximately $471.3 million in Euro denominated commercial paper was designated as a Net Investment Hedge as described in more detail in Note I, Financial Instruments . At December 31, 2016, the Company had no commercial paper borrowings outstanding. In January 2017, the Company also executed a 364-day $1.3 billion committed credit facility (the "2017 Credit Agreement"). The 2017 Credit Agreement consists of a $1.3 billion revolving credit loan and a sub-limit of an amount equal to the Euro equivalent of $400 million for swing line advances. Borrowings under the 2017 Credit Agreement may be made in U.S. Dollars or Euros, pursuant to the terms of the agreement, and bear interest at a floating rate dependent on the denomination of the borrowing. Repayments must be made by January 17, 2018 or upon an earlier termination of the 2017 Credit Agreement at the election of the Company. The 2017 Credit Agreement serves as a liquidity back-stop for the Company’s $3.0 billion U.S. Dollar and Euro commercial paper program, also authorized and amended in January 2017, as discussed above. As of September 30, 2017 , the Company had not drawn on this commitment. As of September 30, 2017 and December 31, 2016 , the Company had not drawn on its existing five-year $1.75 billion committed credit facility.

Notes To Financial Statements [Abstract]
Financial Instruments	Financial Instruments The Company is exposed to market risk from changes in foreign currency exchange rates, interest rates, stock prices and commodity prices. As part of the Company’s risk management program, a variety of financial instruments such as interest rate swaps, currency swaps, purchased currency options, foreign exchange contracts and commodity contracts may be used to mitigate interest rate exposure, foreign currency exposure and commodity price exposure. If the Company elects to do so and if the instrument meets the criteria specified in ASC 815, "Derivatives and Hedging," management designates its derivative instruments as cash flow hedges, fair value hedges or net investment hedges. Generally, commodity price exposures are not hedged with derivative financial instruments and instead are actively managed through customer pricing initiatives, procurement-driven cost reduction initiatives and other productivity improvement projects. Financial instruments are not utilized for speculative purposes. A summary of the fair values of the Company’s financial instruments recorded in the Condensed Consolidated Balance Sheets at September 30, 2017 and December 31, 2016 follows: (Millions of Dollars) Balance Sheet Classification September 30, 2017 December 31, 2016 Balance Sheet Classification September 30, 2017 December 31, 2016 Derivatives designated as hedging instruments: Interest Rate Contracts Cash Flow LT other assets $ — $ — LT other liabilities $ 56.0 $ 47.3 Foreign Exchange Contracts Cash Flow Other current assets 3.5 37.6 Accrued expenses 26.6 1.6 LT other assets 0.9 — LT other liabilities 11.7 — Net Investment Hedge Other current assets 9.9 44.1 Accrued expenses 6.7 1.8 LT other assets — — LT other liabilities 5.7 0.5 Non-derivative designated as hedging instrument: Net Investment Hedge — — Short-term borrowings 471.3 — Total Designated $ 14.3 $ 81.7 $ 578.0 $ 51.2 Derivatives not designated as hedging instruments: Foreign Exchange Contracts Other current assets $ 5.0 $ 28.5 Accrued expenses $ 16.9 $ 46.4 Total Undesignated $ 5.0 $ 28.5 $ 16.9 $ 46.4 The counterparties to all of the above mentioned financial instruments are major international financial institutions. The Company is exposed to credit risk for net exchanges under these agreements, but not for the notional amounts. The credit risk is limited to the asset amounts noted above. The Company limits its exposure and concentration of risk by contracting with diverse financial institutions and does not anticipate non-performance by any of its counterparties. Further, as more fully discussed in Note M, Fair Value Measurements , the Company considers non-performance risk of its counterparties at each reporting period and adjusts the carrying value of these assets accordingly. The risk of default is considered remote. During the nine months ended September 30, 2017 and October 1, 2016 , cash flows related to derivatives, including those that are separately discussed below, resulted in net cash paid of $4.2 million and net cash received of $67.9 million , respectively. CASH FLOW HEDGES As of September 30, 2017 and December 31, 2016 , there was an after-tax mark-to-market loss of $117.1 million and $46.3 million , respectively, reported for cash flow hedge effectiveness in Accumulated other comprehensive loss. An after-tax gain of $12.6 million is expected to be reclassified to earnings as the hedged transactions occur or as amounts are amortized within the next twelve months. The ultimate amount recognized will vary based on fluctuations of the hedged currencies and interest rates through the maturity dates. The tables below detail pre-tax amounts reclassified from Accumulated other comprehensive loss into earnings for active derivative financial instruments during the periods in which the underlying hedged transactions affected earnings for the three and nine months ended September 30, 2017 and October 1, 2016 (in millions): Third Quarter 2017 Gain (Loss) Classification of Gain (Loss) Gain (Loss) Interest Rate Contracts $ (1.6 ) Interest expense $ — $ — Foreign Exchange Contracts $ (26.5 ) Cost of sales $ 3.6 $ — Year-to-Date 2017 Gain (Loss) Classification of Gain (Loss) Gain (Loss) Interest Rate Contracts $ (8.8 ) Interest expense $ — $ — Foreign Exchange Contracts $ (65.1 ) Cost of sales $ 13.3 $ — Third Quarter 2016 Gain (Loss) Classification of Gain (Loss) Gain (Loss) Recognized in Income (Ineffective Portion*) Interest Rate Contracts $ (7.0 ) Interest expense $ — $ — Foreign Exchange Contracts $ (0.9 ) Cost of sales $ (2.3 ) $ — Year-to-Date 2016 Gain (Loss) Classification of Gain (Loss) Gain (Loss) Recognized in Income (Ineffective Portion*) Interest Rate Contracts $ (61.1 ) Interest expense $ — $ — Foreign Exchange Contracts $ (5.3 ) Cost of sales $ 21.3 $ — * Includes ineffective portion and amount excluded from effectiveness testing on derivatives. For the three and nine months ended September 30, 2017 , the hedged items' impact to the Consolidated Statements of Operations and Comprehensive Income was a loss of $3.6 million and $13.3 million , respectively, in Cost of sales, which is offsetting the amounts shown above. For the three and nine months ended October 1, 2016 , the hedged items’ impact to the Consolidated Statements of Operations and Comprehensive Income was a gain of $2.3 million and a loss of $21.3 million , respectively. There was no impact related to the interest rate contracts' hedged items for all periods presented. For the three months ended September 30, 2017 , there was no net impact to earnings for hedged items. For the nine months ended September 30, 2017 , an after-tax gain of $1.4 million was reclassified from Accumulated other comprehensive loss into earnings (inclusive of the gain/loss amortization on terminated derivative instruments) during the periods in which the underlying hedged transactions affected earnings. For the three and nine months ended October 1, 2016 , an after-tax loss of $3.6 million and an after-tax gain of $6.2 million , respectively, was reclassified from Accumulated other comprehensive loss into earnings (inclusive of the gain/loss amortization on terminated derivative instruments) during the periods in which the underlying hedged transactions affected earnings. Interest Rate Contracts The Company enters into interest rate swap agreements in order to obtain the lowest cost source of funds within a targeted range of variable to fixed-debt proportions. At September 30, 2017 and December 31, 2016 , the Company had $400 million of forward starting swaps outstanding which were executed in 2014. The objective of the hedges is to offset the expected variability on future payments associated with the interest rate on debt instruments expected to be issued in 2018. Gains or losses on the swaps are recorded in Accumulated other comprehensive loss and will be subsequently reclassified into earnings as the future interest expense is recognized in earnings or as ineffectiveness occurs. Foreign Currency Contracts Forward Contracts: Through its global businesses, the Company enters into transactions and makes investments denominated in multiple currencies that give rise to foreign currency risk. The Company and its subsidiaries regularly purchase inventory from subsidiaries with functional currencies different than their own, which creates currency-related volatility in the Company’s results of operations. The Company utilizes forward contracts to hedge these forecasted purchases and sales of inventory. Gains and losses reclassified from Accumulated other comprehensive loss for the effective portion of the hedge are recorded in Cost of sales. The ineffective portion, if any, as well as gains and losses incurred after a hedge has been de-designated are not recorded in Accumulated other comprehensive loss, but are recorded directly to the Consolidated Statements of Operations and Comprehensive Income in Other, net. At September 30, 2017 , the notional value of forward currency contracts outstanding was $626.3 million , maturing on various dates through 2018. At December 31, 2016 , the notional value of forward currency contracts outstanding was $503.8 million , maturing on various dates through 2017. Purchased Option Contracts: The Company and its subsidiaries have entered into various intercompany transactions whereby the notional values are denominated in currencies other than the functional currencies of the party executing the trade. In order to better match the cash flows of its intercompany obligations with cash flows from operations, the Company enters into purchased option contracts. Gains and losses reclassified from Accumulated other comprehensive loss for the effective portions of the hedge are recorded in Cost of sales. The ineffective portion, if any, as well as gains and losses incurred after a hedge has been de-designated are not recorded in Accumulated other comprehensive loss, but are recorded directly to the Consolidated Statements of Operations and Comprehensive Income in Other, net. At September 30, 2017 , the notional value of purchased option contracts was $455.0 million maturing on various dates through 2019. As of December 31, 2016 , the notional value of purchased option contracts was $252.0 million , maturing on various dates through 2017. FAIR VALUE HEDGES Interest Rate Risk: In an effort to optimize the mix of fixed versus floating rate debt in the Company’s capital structure, the Company enters into interest rate swaps. In previous years, the Company entered into interest rate swaps on the first five years of the Company's $400 million 5.75% notes due 2053 and interest rate swaps with notional values which equaled the Company's $400 million 3.40% notes due 2021 and the Company's $150 million 7.05% notes due 2028. These interest rate swaps effectively converted the Company's fixed rate debt to floating rate debt based on LIBOR, thereby hedging the fluctuation in fair value resulting from changes in interest rates. In the second quarter of 2016, the Company terminated all of the above interest rate swaps and there were no open contracts as of September 30, 2017 and December 31, 2016 . The terminations resulted in cash receipts of $27.0 million . This gain was deferred and is being amortized to earnings over the remaining life of the notes. Prior to termination of the Company’s interest rate swaps discussed above, the changes in fair value of the swaps and the offsetting changes in fair value related to the underlying notes were recognized in earnings. A summary of fair value adjustments relating to these swaps is as follows (in millions): Third Quarter 2016 Year-to-Date 2016 Income Statement Classification Gain/(Loss) on Gain/(Loss) on Gain/(Loss) on Gain/(Loss) on Interest Expense $ — $ — $ (3.3 ) $ 3.8 *Includes ineffective portion and amount excluded from effectiveness testing. Amortization of the gain/loss on terminated swaps of $0.8 million and $2.4 million are reported as a reduction of interest expense for the three and nine months ended September 30, 2017 , respectively. In addition to the fair value adjustments in the table above, net swap accruals and amortization of the gain/loss on terminated swaps of $0.8 million and $6.1 million are reported as a reduction of interest expense for the three and nine months ended October 1, 2016 , respectively. Interest expense on the underlying debt when the hedge was active was $19.9 million for the nine months ended October 1, 2016 . NET INVESTMENT HEDGES Foreign Exchange Contracts: The Company utilizes net investment hedges to offset the translation adjustment arising from re-measurement of its investment in the assets and liabilities of its foreign subsidiaries. The total after-tax amounts in Accumulated other comprehensive loss were gains of $3.3 million and $88.6 million at September 30, 2017 and December 31, 2016 , respectively. As of September 30, 2017 , the Company had foreign exchange forward contracts maturing on various dates in 2017 with notional values totaling $749.6 million outstanding hedging a portion of its British pound sterling, Mexican peso, Swedish krona, Euro and Canadian dollar denominated net investments; a cross currency swap with a notional value totaling $250.0 million maturing in 2023 hedging a portion of its Japanese yen denominated net investment; and Euro denominated commercial paper with a value of $471.3 million maturing in 2017 hedging a portion of its Euro denominated net investments. As of December 31, 2016 , the Company had foreign exchange contracts maturing on various dates in 2017 with notional values totaling $1.0 billion outstanding hedging a portion of its British pound sterling, Mexican peso, Swedish krona, Euro and Canadian dollar denominated net investments, and a cross currency swap with a notional value totaling $250.0 million maturing 2023 hedging a portion of its Japanese yen denominated net investment. For the nine months ended September 30, 2017 and October 1, 2016 , maturing foreign exchange contracts resulted in net cash paid of $31.6 million and net cash received of $63.3 million , respectively. Gains and losses on net investment hedges remain in Accumulated other comprehensive income (loss) until disposal of the underlying assets. Gains and losses after a hedge has been de-designated are recorded directly to the Consolidated Statements of Operations and Comprehensive Income in Other, net. The pre-tax gain or loss from fair value changes was as follows (in millions): Third Quarter 2017 Year-to-Date 2017 Income Statement Classification Amount Effective Portion Ineffective Amount Effective Portion Ineffective Other, net $ (42.3 ) $ — $ — $ (131.3 ) $ — $ — Third Quarter 2016 Year-to-Date 2016 Income Statement Classification Amount Effective Portion Ineffective Amount Effective Portion Ineffective Other, net $ 16.0 $ — $ — $ 53.8 $ — $ — *Includes ineffective portion and amount excluded from effectiveness testing. UNDESIGNATED HEDGES Foreign Exchange Contracts: Currency swaps and foreign exchange forward contracts are used to reduce risks arising from the change in fair value of certain foreign currency denominated assets and liabilities (such as affiliate loans, payables and receivables). The objective of these practices is to minimize the impact of foreign currency fluctuations on operating results. The total notional amount of the forward contracts outstanding at September 30, 2017 was $1.3 billion , maturing on various dates through 2018. The total notional amount of the forward contracts outstanding at December 31, 2016 was $1.5 billion , maturing on various dates in 2017. The income statement impacts related to derivatives not designated as hedging instruments for the three and nine months ended September 30, 2017 and October 1, 2016 are as follows (in millions): Derivatives Not Designated as Hedging Instruments under ASC 815 Income Statement Third Quarter 2017 Year-to-Date 2017 Foreign Exchange Contracts Other, net $ 13.9 $ 43.6 Derivatives Not Designated as Hedging Instruments under ASC 815 Income Statement Third Quarter 2016 Year-to-Date 2016 Foreign Exchange Contracts Other, net $ 12.5 $ (24.5 )

Notes To Financial Statements [Abstract]
Equity Arrangements	Equity Arrangements In 2016, the Company repurchased 3,940,087 shares of common stock for approximately $374.1 million . Additionally, the Company net-share settled capped call options on its common stock and received 711,376 shares during 2016. Refer to Note J, Capital Stock , of the Company's Form 10-K for the year ended December 31, 2016 . In November 2016, the Company issued 3,504,165 shares of common stock to settle the purchase contracts of the 2013 Equity Units. See further discussion below. In March 2015, the Company entered into a forward share purchase contract with a financial counterparty for 3,645,510 shares of common stock. The contract obligates the Company to pay $350.0 million , plus an additional amount related to the forward component of the contract. In November 2016, the Company amended the settlement date to April 2019, or earlier at the Company's option. The reduction of common shares outstanding was recorded at the inception of the forward share purchase contract in March 2015 and factored into the calculation of weighted-average shares outstanding at that time. In October 2014, the Company entered into a forward share purchase contract on its common stock. The contract obligated the Company to pay $150.0 million , plus an additional amount related to the forward component of the contract, to the financial institution counterparty not later than October 2016, or earlier at the Company’s option, for the 1,603,822 shares purchased. The reduction of common shares outstanding was recorded at the inception of the forward share purchase contract in October 2014 and factored into the calculation of weighted-average shares outstanding at that time. In October 2016, the Company physically settled the contract, receiving 1,603,822 shares for a settlement amount of $147.4 million . Refer to Note J, Capital Stock , of the Company's Form 10-K for the year ended December 31, 2016 , for additional disclosure related to the shares physically received. As described more fully in Note H, Long-Term Debt and Financing Arrangements , of the Company’s Form 10-K for the year ended December 31, 2016 , in November 2013, the Company purchased from certain financial institutions “out-of-the-money” capped call options on 12.2 million shares of its common stock (subject to customary anti-dilution adjustments). In February 2015, the Company net-share settled 9.1 million of the 12.2 million capped call options on its common stock and received 911,077 shares using an average reference price of $96.46 per common share. In February 2016, the Company net-share settled the remaining 3.1 million capped call options on its common stock and received 293,142 shares using an average reference price of $94.34 per common share. Equity Units and Capped Call Transactions As described more fully in Note H, Long-Term Debt and Financing Arrangements , of the Company’s Form 10-K for the year ended December 31, 2016 , in December 2013, the Company issued Equity Units comprised of $345.0 million of Notes and Equity Purchase Contracts. The Equity Purchase Contracts obligated the holders to purchase on November 17, 2016, for $100 , between 1.0122 and 1.2399 shares of the Company’s common stock, which were equivalent to an initial settlement price of $98.80 and $80.65 , respectively, per share of common stock. In accordance with the Equity Purchase Contracts, on November 17, 2016, the Company issued 3,504,165 common shares and received additional cash proceeds of $345.0 million. The conversion rate used in calculating the average of the daily volume-weighted-average price of common stock during the market value averaging period, was 1.0157 (equivalent to the minimum settlement rate and a conversion price of $98.45 per common share) on November 17, 2016. Contemporaneously with the issuance of the Equity Units described above, the Company paid $9.7 million , or an average of $2.77 per option, to enter into capped call transactions on 3.5 million shares of common stock with a major financial institution. The purpose of the capped call transactions was to offset the potential economic dilution associated with the common shares issuable upon the settlement of the Equity Purchase Contracts. Refer to Note H, Long-Term Debt and Financing Arrangements , of the Company’s Form 10-K for the year ended December 31, 2016 for further discussion. The $9.7 million premium paid was recorded as a reduction to equity. The capped call transactions covered, subject to customary anti-dilution adjustments, the number of shares equal to the number of shares issuable upon settlement of the Equity Purchase Contracts at the 1.0122 minimum settlement rate. In October and November 2016, the Company's capped call options on its common stock expired and were net-share settled resulting in the Company physically receiving 418,234 shares using an average reference price of $117.84 per common share. $750 Million Equity Units and Capped Call Transactions In May 2017, the Company issued 7,500,000 Equity Units with a total notional value of $750.0 million (“$750 million Equity Units”). Each unit has a stated amount of $100 and initially consists of a three-year forward stock purchase contract (“2020 Purchase Contracts”) for the purchase of a variable number of shares of common stock, on May 15, 2020, for a price of $100 , and a 10% beneficial ownership interest in one share of 0% Series C Cumulative Perpetual Convertible Preferred Stock, without par, with a liquidation preference of $1,000 per share (“Series C Preferred Stock”). The Company received approximately $727.5 million in cash proceeds from the $750 million Equity Units, net of underwriting costs and commissions, before offering expenses, and issued 750,000 shares of Series C Preferred Stock, recording $750.0 million in preferred stock. The proceeds were used for general corporate purposes, including repayment of short-term borrowings. The Company also used $25.1 million of the proceeds to enter into capped call transactions utilized to hedge potential economic dilution as described in more detail below. Convertible Preferred Stock In May 2017, the Company issued 750,000 shares of Series C Preferred Stock, without par, with a liquidation preference of $1,000 per share. The convertible preferred stock will initially not bear any dividends and the liquidation preference of the convertible preferred stock will not accrete. The convertible preferred stock has no maturity date, and will remain outstanding unless converted by holders or redeemed by the Company. Holders of shares of the convertible preferred stock will generally have no voting rights. The Series C Preferred Stock is pledged as collateral to support holders’ purchase obligations under the 2020 Purchase Contracts and can be remarketed. In connection with any successful remarketing, the Company may (but is not required to) modify certain terms of the convertible preferred stock, including the dividend rate, the conversion rate, and the earliest redemption date. After any successful remarketing in connection with which the dividend rate on the convertible preferred stock is increased, the Company will pay cumulative dividends on the convertible preferred stock, if declared by the board of directors, quarterly in arrears from the applicable remarketing settlement date. On and after May 15, 2020, the Series C Preferred Stock may be converted into common stock at the option of the holder. The initial conversion rate was 6.1627 shares of common stock per one share of Series C Preferred Stock, which is equivalent to an initial conversion price of approximately $162.27 per share of common stock. As of September 30, 2017, due to the customary anti-dilution provisions, the conversion rate was 6.1649 , equivalent to a conversion price of approximately $162.21 per share of common stock. At the election of the Company, upon conversion, the Company may deliver cash, common stock, or a combination thereof. The Company may not redeem the Series C Preferred Stock prior to June 22, 2020. At the election of the Company, on or after June 22, 2020, the Company may redeem for cash, all or any portion of the outstanding shares of the Series C Preferred Stock at a redemption price equal to 100% of the liquidation preference, plus any accumulated and unpaid dividends. If the Company calls the Series C Preferred Stock for redemption, holders may convert their shares immediately preceding the redemption date. 2020 Purchase Contracts The 2020 Purchase Contracts obligate the holders to purchase, on May 15, 2020, for a price of $100 in cash, a maximum number of 5.4 million shares of the Company’s common stock (subject to customary anti-dilution adjustments). The 2020 Purchase Contract holders may elect to settle their obligation early, in cash. The Series C Preferred Stock is pledged as collateral to guarantee the holders’ obligations to purchase common stock under the terms of the 2020 Purchase Contracts. The initial settlement rate determining the number of shares that each holder must purchase will not exceed the maximum settlement rate, and is determined over a market value averaging period immediately preceding May 15, 2020. The initial maximum settlement rate of 0.7241 was calculated using an initial reference price of $138.10 , equal to the last reported sale price of the Company's common stock on May 11, 2017. As of September 30, 2017, due to the customary anti-dilution provisions, the maximum settlement rate was 0.7244 , equivalent to a reference price of $138.05 . If the applicable market value of the Company's common stock is less than or equal to the reference price, the settlement rate will be the maximum settlement rate; and if the applicable market value of common stock is greater than the reference price, the settlement rate will be a number of shares of the Company's common stock equal to $100 divided by the applicable market value. Upon settlement of the 2020 Purchase Contracts, the Company will receive additional cash proceeds of $750 million . The Company will pay the holders of the 2020 Purchase Contracts quarterly payments (“Contract Adjustment Payments”) at a rate of 5.375% per annum, payable quarterly in arrears on February 15, May 15, August 15 and November 15, commencing August 15, 2017. The $116.9 million present value of the Contract Adjustment Payments reduced Shareowners’ Equity at inception. As each quarterly Contract Adjustment Payment is made, the related liability is reduced and the difference between the cash payment and the present value will accrete to interest expense, approximately $1.3 million per year over the three-year term. As of September 30, 2017, the present value of the Contract Adjustment Payments was $107.5 million . The holders can settle the purchase contracts early, for cash, subject to certain exceptions and conditions in the prospectus supplement. Upon early settlement of any purchase contracts, the Company will deliver the number of shares of its common stock equal to 85% of the number of shares of common stock that would have otherwise been deliverable. Capped Call Transactions In order to offset the potential economic dilution associated with the common shares issuable upon conversion of the Series C Preferred Stock, to the extent that the conversion value of the convertible preferred stock exceeds its liquidation preference, the Company entered into capped call transactions with three major financial institutions (the “counterparties”). The capped call transactions have a term of approximately three years and are intended to cover the number of shares issuable upon conversion of the Series C Preferred Stock. Subject to customary anti-dilution adjustments, the capped call has an initial lower strike price of $162.27 , which corresponds to the minimum 6.1627 settlement rate of the Series C Preferred Stock, and an upper strike price of $179.53 , which is approximately 30% higher than the closing price of the Company's common stock on May 11, 2017. As of September 30, 2017, due to the customary anti-dilution provisions, the capped call transactions had an adjusted lower strike price of $162.21 and an adjusted upper strike price of $179.47 . The capped call transactions may be settled by net share settlement (the default settlement method) or, at the Company’s option and subject to certain conditions, cash settlement, physical settlement or modified physical settlement. The number of shares the Company will receive will be determined by the terms of the contracts using a volume-weighted average price calculation for the market value of the Company's common stock, over an averaging period. The market value determined will then be measured against the applicable strike price of the capped call transactions. The Company expects the capped call transactions to offset the potential dilution upon conversion of the Series C Preferred Stock if the calculated market value is greater than the lower strike price but less than or equal to the upper strike price of the capped call transactions. Should the calculated market value exceed the upper strike price of the capped call transactions, the dilution mitigation will be limited based on such capped value as determined under the terms of the contracts. With respect to the impact on the Company, the capped call transactions and $750 million Equity Units, when taken together, result in the economic equivalent of having the conversion price on $750 million Equity Units at $179.47 , the upper strike of the capped call as of September 30, 2017 . The Company paid $25.1 million , or an average of $5.43 per option, to enter into capped call transactions on 4.6 million shares of common stock. The $25.1 million premium paid was a reduction of Shareowners’ Equity. The aggregate fair value of the options at September 30, 2017 was $28.2 million .

Fair Value Measurements

Fair Value Measurements	9 Months Ended
	Sep. 30, 2017
Notes To Financial Statements [Abstract]
Fair Value Measurements	Fair Value Measurements FASB ASC 820, "Fair Value Measurement," defines, establishes a consistent framework for measuring, and expands disclosure requirements about fair value. ASC 820 requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy: Level 1 — Quoted prices for identical instruments in active markets. Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs and significant value drivers are observable. Level 3 — Instruments that are valued using unobservable inputs. The Company holds various financial instruments that are employed to manage risks, including foreign currency and interest rate exposures. These financial instruments are carried at fair value and are included within the scope of ASC 820. The Company determines the fair values of these financial instruments through the use of matrix or model pricing, which utilizes observable inputs such as market interest and currency rates. When determining the fair values of these financial instruments for which Level 1 evidence does not exist, the Company considers various factors including the following: exchange or market price quotations of similar instruments, time value and volatility factors, the Company’s own credit rating and the credit rating of the counter-party. The following table presents the Company’s financial assets and liabilities that are measured at fair value on a recurring basis for each of the hierarchy levels: (Millions of Dollars) Total Level 1 Level 2 Level 3 September 30, 2017 Money market fund $ 3.2 $ 3.2 $ — $ — Derivative assets $ 19.3 $ — $ 19.3 $ — Derivative and non-derivative liabilities $ 594.9 $ — $ 594.9 $ — Contingent consideration liability $ 84.0 $ — $ — $ 84.0 December 31, 2016 Money market fund $ 4.3 $ 4.3 $ — $ — Derivative assets $ 110.2 $ — $ 110.2 $ — Derivative liabilities $ 97.6 $ — $ 97.6 $ — The following table presents the carrying values and fair values of the Company's financial assets and liabilities, as well as the Company's debt, as of September 30, 2017 and December 31, 2016 : September 30, 2017 December 31, 2016 (Millions of Dollars) Carrying Value Fair Value Carrying Value Fair Value Other investments $ 8.9 $ 9.3 $ 8.9 $ 9.2 Derivative assets $ 19.3 $ 19.3 $ 110.2 $ 110.2 Derivative and non-derivative liabilities $ 594.9 $ 594.9 $ 97.6 $ 97.6 Long-term debt, including current portion $ 3,826.7 $ 4,022.4 $ 3,823.1 $ 3,967.4 As discussed in Note F, Acquisitions, the Company recorded a contingent consideration liability in the first quarter of 2017 relating to the Craftsman brand acquisition representing the Company's obligation to make future payments to Sears Holdings of between 2.5% and 3.5% on sales of Craftsman products in new Stanley Black & Decker channels through March 2032, which was initially valued at $84.0 million at the acquisition date. The first payment is due the first quarter of 2020 relating to royalties owed for the previous eleven quarters, and future payments will be due quarterly through the first quarter of 2032. The fair value was estimated using Level 3 inputs including future sales projections, which are subject to change, and the contractual royalty rates. There was no change in the fair value of the contingent consideration as of September 30, 2017 . The Company had no other significant non-recurring fair value measurements, nor any other financial assets or liabilities measured using Level 3 inputs, during the nine months of 2017 or 2016 . The money market fund and other investments outlined in the tables above relate to the West Coast Loading Corporation ("WCLC") trust and are considered Level 1 instruments within the fair value hierarchy. The long-term debt instruments are considered Level 2 instruments and are measured using the stated cash flows in each obligation discounted at the Company’s marginal borrowing rates. The differences between the carrying values and fair values of long-term debt are attributable to the stated interest rates differing from the Company's marginal borrowing rates. The fair values of the Company's variable rate short-term borrowings approximate their carrying values at September 30, 2017 and December 31, 2016 . The fair values of foreign currency and interest rate swap agreements, comprising the derivative assets and liabilities in the table above, are based on current settlement values. As discussed in Note D, Financing Receivables , the Company has a deferred purchase price receivable related to sales of trade receivables. The deferred purchase price receivable will be repaid in cash as receivables are collected, generally within 30 days, and as such the carrying value of the receivable approximates fair value. Refer to Note I, Financial Instruments , for more details regarding financial instruments, Note R, Commitments and Contingencies, for more details regarding the other investments related to the WCLC trust, and Note H, Long-Term Debt and Financing Arrangements , for more information regarding the carrying values of the long-term debt.

This amount reflects $34.4 million of net severance charges associated with the reduction of approximately 1,463 employees and $8.5 million of facility closure and other restructuring costs. For the three months ended September 30, 2017 , the Company recognized net restructuring charges of $19.1 million . This amount reflects $16.3 million of net severance charges associated with the reduction of approximately 1,138 employees and $2.8 million of facility closure and other restructuring costs. The majority of the $32.0 million of reserves remaining as of September 30, 2017 is expected to be utilized within the next 12 months. Segments: The $43 million of net restructuring charges for the nine months ended September 30, 2017 includes: $18 million pertaining to the Tools & Storage segment; $17 million pertaining to the Security segment; $7 million pertaining to the Industrial segment and $1 million pertaining to Corporate. The $19 million of net restructuring charges for the three months ended September 30, 2017 includes: $9 million pertaining to the Tools & Storage segment; $8 million pertaining to the Security segment and $2 million pertaining to the Industrial segment.

Income Taxes

Income Taxes	9 Months Ended
	Sep. 30, 2017
Notes To Financial Statements [Abstract]
Income Taxes	Income Taxes The Company recognized income tax expense of $79.8 million and $239.8 million for the three and nine months ended September 30, 2017 , respectively, resulting in effective tax rates of 22.5% and 20.2% , respectively. The effective tax rates differ from the U.S. statutory tax rate during these periods primarily due to a portion of the Company’s earnings being realized in lower-taxed foreign jurisdictions, the utilization of U.S. tax attributes during the first quarter of 2017 due to the divestiture of the mechanical security businesses, the favorable settlement of certain income tax audits during the second quarter of 2017, and the acceleration of certain tax credits resulting in a tax benefit during the third quarter of 2017. Non-deductible transaction costs and other acquisition-related restructuring items partially offset the net tax benefits mentioned above for the three and nine months ended September 30, 2017 . Excluding the impact of the divestitures and acquisition-related charges for the three and nine months ended September 30, 2017 , the effective tax rates were 23.0% and 23.7% , respectively. The Company recognized income tax expense of $78.7 million and $234.7 million for the three and nine months ended October 1, 2016 , respectively, resulting in effective tax rates of 24.0% and 24.9% , respectively. The effective tax rates differed from the U.S. statutory tax rate during these periods primarily due to a portion of the Company’s earnings being realized in lower-taxed foreign jurisdictions, the finalization of audit settlements during the first quarter of 2016, adjustments to tax positions relating to undistributed foreign earnings during the second quarter of 2016, and adjustments relating to the filing of certain U.S. and foreign corporate income tax returns during the third quarter of 2016. The Company is subject to the examination of its income tax returns by the Internal Revenue Service and other taxing authorities both domestically and internationally. The final outcome of the future tax consequences of these examinations and legal proceedings, as well as the outcome of competent authority proceedings, changes and interpretation in regulatory tax laws, or expiration of statute of limitations could impact the Company’s financial statements. Accordingly, the Company has tax reserves recorded for which it is reasonably possible that the amount of the unrecognized tax benefit will increase or decrease which could have a material effect on the financial results for any particular fiscal quarter or year. However, based on the uncertainties associated with litigation and the status of examinations, including the protocols of finalizing audits by the relevant tax authorities which could include formal legal proceedings, it is not possible to estimate the impact of any such change.

Commitments and Contingencies

Commitments and Contingencies	9 Months Ended

Notes To Financial Statements [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is involved in various legal proceedings relating to environmental issues, employment, product liability, workers’ compensation claims and other matters. The Company periodically reviews the status of these proceedings with both inside and outside counsel, as well as an actuary for risk insurance. Management believes that the ultimate disposition of these matters will not have a material adverse effect on operations or financial condition taken as a whole. In connection with the 2010 merger with Black & Decker, the Company assumed certain commitments and contingent liabilities. Black & Decker is a party to litigation and administrative proceedings with respect to claims involving the discharge of hazardous substances into the environment. Some of these assert claims for damages and liability for remedial investigations and clean-up costs with respect to sites that have never been owned or operated by Black & Decker but at which Black & Decker has been identified as a potentially responsible party ("PRP"). Other matters involve current and former manufacturing facilities. The Environmental Protection Agency (“EPA”) has asserted claims in federal court in Rhode Island against certain current and former affiliates of Black & Decker related to environmental contamination found at the Centredale Manor Restoration Project Superfund ("Centredale") site, located in North Providence, Rhode Island. The EPA has discovered a variety of contaminants at the site, including but not limited to, dioxins, polychlorinated biphenyls, and pesticides. The EPA alleges that Black & Decker and certain of its current and former affiliates are liable for site clean-up costs under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") as successors to the liability of Metro-Atlantic, Inc., a former operator at the site, and demanded reimbursement of the EPA’s costs related to this site. Black & Decker and certain of its current and former affiliates contest the EPA's allegation that they are responsible for the contamination, and have asserted contribution claims, counterclaims and cross-claims against a number of other PRPs, including the federal government as well as insurance carriers. The EPA released its Record of Decision ("ROD") in September 2012, which identified and described the EPA's selected remedial alternative for the site. Black & Decker and certain of its current and former affiliates are contesting the EPA's selection of the remedial alternative set forth in the ROD, on the grounds that the EPA's actions were arbitrary and capricious and otherwise not in accordance with law, and have proposed other equally-protective, more cost-effective alternatives. On June 10, 2014, the EPA issued an Administrative Order under Sec. 106 of CERCLA, instructing Emhart Industries, Inc. and Black & Decker to perform the remediation of Centredale pursuant to the ROD. Black & Decker and Emhart Industries, Inc. dispute the factual, legal and scientific bases cited by the EPA for such an Order and have provided the EPA with numerous good-faith bases for Black & Decker’s and Emhart Industries, Inc.’s declination to comply with the Order at this time. Black & Decker and Emhart Industries, Inc. continue to vigorously litigate the issue of their liability for environmental conditions at the Centredale site, including the completion of the Phase 1 trial in late July, 2015 and the completion of the Phase 2 trial in April, 2017. The Court in Phase 1 of the trial found that dioxin contamination at the Centredale site was not “divisible,” and that Emhart was jointly and severally liable for dioxin contamination at the Site. In its Phase 2 Findings of Fact and Conclusions of Law, entered on August 17, 2017, the Court found that certain components of EPA’s selected remedy were arbitrary and capricious, however, and remanded the matter to the EPA while retaining jurisdiction over the ongoing remedy selection and implementation process. The Court also held in Phase 2 that Black & Decker had sufficient cause for its declination to comply with EPA’s June 10, 2014 Order and that no associated civil penalties or fines were warranted. The United States has filed a Motion for Reconsideration concerning the Court’s Phase 2 rulings, and a ruling on that motion is not expected until at least early 2018. The 3rd Phase of the litigation / trial, which is in its very early stages, will address the potential allocation of liability to other parties who may have contributed to contamination of the Site with dioxins, PCB’s and other contaminants of concern. The Company's estimated remediation costs related to the Centredale site (including the EPA’s past costs as well as costs of additional investigation, remediation, and related costs such as EPA’s oversight costs, less escrowed funds contributed by primary PRPs who have reached settlement agreements with the EPA), which the Company considers to be probable and reasonably estimable, range from approximately $68.1 million to $139.7 million , with no amount within that range representing a more likely outcome until such time as the litigation is resolved through judgment or compromise. The Company’s reserve for this environmental remediation matter of $68.1 million reflects the fact that the EPA considers Metro-Atlantic, Inc. to be a primary source of contamination at the site. As the specific nature of the environmental remediation activities that may be mandated by the EPA at this site have not yet been finally determined through the on-going litigation, the ultimate remedial costs associated with the site may vary from the amount accrued by the Company at September 30, 2017 . In the normal course of business, the Company is involved in various lawsuits and claims. In addition, the Company is a party to a number of proceedings before federal and state regulatory agencies relating to environmental remediation. Also, the Company, along with many other companies, has been named as a PRP in a number of administrative proceedings for the remediation of various waste sites, including 29 active Superfund sites. Current laws potentially impose joint and several liabilities upon each PRP. In assessing its potential liability at these sites, the Company has considered the following: whether responsibility is being disputed, the terms of existing agreements, experience at similar sites, and the Company’s volumetric contribution at these sites. The Company’s policy is to accrue environmental investigatory and remediation costs for identified sites when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. In the event that no amount in the range of probable loss is considered most likely, the minimum loss in the range is accrued. The amount of liability recorded is based on an evaluation of currently available facts with respect to each individual site and includes such factors as existing technology, presently enacted laws and regulations, and prior experience in remediation of contaminated sites. The liabilities recorded do not take into account any claims for recoveries from insurance or third parties. As assessments and remediation progress at individual sites, the amounts recorded are reviewed periodically and adjusted to reflect additional technical and legal information that becomes available. As of September 30, 2017 and December 31, 2016 the Company had reserves of $175.0 million and $160.9 million , respectively, for remediation activities associated with Company-owned properties, as well as for Superfund sites, for losses that are probable and estimable. Of the 2017 amount, $21.7 million is classified as current and $153.3 million as long-term which is expected to be paid over the estimated remediation period. As of September 30, 2017 , the Company has recorded $12.1 million in other assets related to funding received by the EPA and placed in a trust in accordance with the final settlement with the EPA, embodied in a Consent Decree approved by the United States District Court for the Central District of California on July 3, 2013. Per the Consent Decree, Emhart Industries, Inc. (a dissolved, former indirectly wholly-owned subsidiary of The Black & Decker Corporation) (“Emhart”) has agreed to be responsible for an interim remedy at a site located in Rialto, California and formerly operated by West Coast Loading Corporation (“WCLC”), a defunct company for which Emhart was alleged to be liable as a successor. The remedy will be funded by (i) the amounts received from the EPA as gathered from multiple parties, and, to the extent necessary, (ii) Emhart's affiliate. The interim remedy requires the construction of a water treatment facility and the filtering of ground water at or around the site for a period of approximately 30 years or more. Accordingly, as of September 30, 2017 , the Company's cash obligation associated with the aforementioned remediation activities including WCLC is $162.9 million . The range of environmental remediation costs that is reasonably possible is $142.4 million to $276.2 million which is subject to change in the near term. The Company may be liable for environmental remediation of sites it no longer owns. Liabilities have been recorded on those sites in accordance with policy. The Company and approximately 60 other companies comprise the Lower Passaic Cooperating Parties Group (the “CPG”). The CPG members and other companies are parties to a May 2007 Administrative Settlement Agreement and Order on Consent (“AOC”) with the EPA to perform a remedial investigation/feasibility study (“RI/FS”) of the lower seventeen miles of the Lower Passaic River in New Jersey (the “River”). The Company’s potential liability stems from former operations in Newark, New Jersey. As an interim step related to the 2007 AOC, on June 18, 2012, the CPG members voluntarily entered into an AOC with the EPA for remediation actions focused solely at mile 10.9 of the River. The Company’s estimated costs related to the RI/FS and focused remediation action at mile 10.9, based on an interim allocation, are included in its environmental reserves. On April 11, 2014, the EPA issued a Focused Feasibility Study (“FFS”) and proposed plan which addressed various early action remediation alternatives for the lower 8.3 miles of the River. The EPA received public comment on the FFS and proposed plan (including comments from the CPG and other entities asserting that the FFS and proposed plan do not comply with CERCLA) which public comment period ended on August 20, 2014. The CPG submitted to the EPA a draft RI report in February 2015 and draft FS report in April 2015 for the entire lower seventeen miles of the River. On March 4, 2016, the EPA issued a ROD selecting the remedy for the lower 8.3 miles of the River. The cleanup plan adopted by the EPA is now considered a final action for the lower 8.3 miles of the River and will include the removal of 3.5 million cubic yards of sediment, placement of a cap over the entire lower 8.3 miles of the River, and, according to the EPA, will cost approximately $1.4 billion and take 6 years to implement after the remedial design is completed. The EPA estimates that the remedial design will take four years to complete. The Company and 105 other parties received a letter dated March 31, 2016 from the EPA notifying such parties of potential liability for the costs of the cleanup of the lower 8.3 miles of the River and a letter dated March 30, 2017 stating that the EPA had offered 20 of the parties (not including the Company) an early cash out settlement. In a letter dated May 17, 2017, the EPA stated that these 20 parties did not discharge any of the eight hazardous substances identified in the lower 8.3 mile ROD as the contaminants of concern. In the March 30, 2017 letter, the EPA stated that other parties who did not discharge dioxins, furans or polychlorinated biphenyls (which are considered the contaminants of concern posing the greatest risk to human health or the environment) may also be eligible for cash out settlement, but expects those parties’ allocation to be determined through a complex settlement analysis using a third party allocator. The Company asserts that it did not discharge dioxins, furans or polychlorinated biphenyls and should be eligible for a cash out settlement.There has been no determination as to how the RI/FS will be modified in light of the EPA’s decision to implement a final action for the lower 8.3 miles of the River. At this time, the Company cannot reasonably estimate its liability related to the remediation efforts, excluding the RI/FS and remediation actions at mile 10.9, as the RI/FS is ongoing, the ultimate remedial approach and associated cost for the upper portion of the River has not yet been determined, and the parties that will participate in funding the remediation and their respective allocations are not yet known. On September 30, 2016, Occidental Chemical Corporation entered into an agreement with EPA to perform the remedial design for the cleanup plan for the lower 8.3 miles of the river. Per the terms of a Final Order and Judgment approved by the United States District Court for the Middle District of Florida on January 22, 1991, Emhart is responsible for a percentage of remedial costs arising out of the Kerr McGee Chemical Corporation Superfund Site located in Jacksonville, Florida. On March 15, 2017, the Company received formal notification from the EPA that the EPA had issued a ROD selecting the preferred alternative identified in the Proposed Cleanup Plan. The cleanup adopted by the EPA is currently estimated to cost approximately $68.7 million. Accordingly, in the first quarter of 2017, the Company increased its reserve by $17.1 million which was recorded in Other, net in the Consolidated Statements of Operations and Comprehensive Income. The amount recorded for identified contingent liabilities is based on estimates. Amounts recorded are reviewed periodically and adjusted to reflect additional technical and legal information that becomes available. Actual costs to be incurred in future periods may vary from the estimates, given the inherent uncertainties in evaluating certain exposures. Subject to the imprecision in estimating future contingent liability costs, the Company does not expect that any sum it may have to pay in connection with these matters in excess of the amounts recorded will have a materially adverse effect on its financial position, results of operations or liquidity.
