Summary of Significant Accounting Policies	Dec. 31, 2016
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations Wolverine World Wide, Inc. is a leading designer, manufacturer and marketer of a broad range of quality casual footwear and apparel; performance outdoor and athletic footwear and apparel; children’s footwear, industrial work shoes, boots and apparel; and uniform shoes and boots. The Company’s portfolio of owned and licensed brands includes: Bates^®, Cat^®, Chaco^®, Harley-Davidson^®, Hush Puppies^®, HyTest^®, Keds^®, Merrell^®, Saucony^®, Sebago^®, Sperry^®, Stride Rite^® and Wolverine^®. Licensing and distribution arrangements with third parties extend the global reach of the Company’s brand portfolio. The Company also operates a consumer-direct division to market both its own brands and branded footwear and apparel from other manufacturers, as well as a leathers division that markets Wolverine Performance Leathers™. Principles of Consolidation The consolidated financial statements include the accounts of Wolverine World Wide, Inc. and its majority-owned subsidiaries (collectively, the “Company”). All intercompany accounts and transactions have been eliminated in consolidation. Fiscal Year The Company’s fiscal year is the 52- or 53-week period that ends on the Saturday nearest to December 31. Fiscal years 2016 and 2015 had 52 weeks and fiscal 2014 contained 53 weeks. Beginning in fiscal 2017, the Company's fiscal year will be comprised of four 13 week quarters. The fiscal year end will continue to be on the Saturday nearest to December 31. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Revenue Recognition Revenue is recognized on the sale of products manufactured or sourced by the Company when the related goods have been shipped, legal title has passed to the customer and collectability is reasonably assured. Revenue generated through licensees and distributors involving products bearing the Company’s trademarks is recognized as earned according to stated contractual terms upon either the purchase or shipment of branded products by licensees and distributors. Retail store revenue is recognized at time of sale. The Company records provisions for estimated sales returns and allowances at the time of sale based on historical rates of returns and allowances and specific identification of outstanding returns not yet received from customers. However, estimates of actual returns and allowances in any future period are inherently uncertain and actual returns and allowances may differ from these estimates. If actual or expected future returns and allowances were significantly greater or less than established reserves, a reduction or increase to net revenues would be recorded in the period this determination was made. Cost of Goods Sold Cost of goods sold includes the actual product costs, including inbound freight charges and certain outbound freight charges, purchasing, sourcing, inspection and receiving costs. Warehousing costs are included in selling, general and administrative expenses. Shipping and Handling Costs Shipping and handling costs that are charged to and reimbursed by a customer are recognized as revenue, while the related expenses incurred by the Company are recorded as cost of goods sold. Advertising Costs Advertising costs are expensed as incurred, except for certain materials that are expensed the first time that the advertising takes place. Advertising expenses were $121.5 million, $137.2 million and $126.6 million for fiscal years 2016, 2015 and 2014, respectively. Prepaid advertising totaled $4.0 million and $6.9 million as of December 31, 2016 and January 2, 2016, respectively. Cash Equivalents Cash equivalents include highly liquid investments with an original maturity of three months or less. Cash equivalents are stated at cost, which approximates market. Allowance for Uncollectible Accounts The Company maintains an allowance for uncollectible accounts receivable for estimated losses resulting from its customers’ failure to make required payments. Company management evaluates the allowance for uncollectible accounts receivable based on a review of current customer status and historical collection experience. Inventories The Company values its inventory at the lower of cost or market. Cost is determined by the LIFO method for all domestic raw materials and work-in-process inventories and certain domestic finished goods inventories. Cost is determined using the FIFO method for all raw materials, work-in-process and finished goods inventories in foreign countries; certain domestic finished goods inventories; and for all finished goods inventories of the Company’s consumer-direct business, due to the unique nature of those operations. The Company has applied these inventory cost valuation methods consistently from year to year. Property, Plant and Equipment Property, plant and equipment are stated on the basis of cost and include expenditures for computer hardware and software, store furniture and fixtures, office furniture and machinery and equipment. Normal repairs and maintenance are expensed as incurred. Depreciation of property, plant and equipment is computed using the straight-line method. The depreciable lives range from 14 to 20 years for buildings and improvements, from 5 to 10 years for leasehold improvements and from 3 to 10 years for machinery, equipment and software. Operating Leases The Company leases its retail stores and certain distribution and office facilities under operating leases. In addition to the minimum lease payments, leases may include rent escalation clauses, contingent rental expense and lease incentives, including rent holidays and tenant improvement allowances. Rent expense is recognized on a straight-line basis over the term of the lease from the time at which the Company takes possession of the property. Landlord-provided tenant improvement allowances are recorded in other liabilities and amortized as a credit to rent expense over the term of the lease. Leasehold improvements are depreciated at the lesser of the estimated useful life or lease term, including reasonably-assured lease renewals as determined at lease inception. Deferred Financing Costs Deferred financing costs represent commitment fees, legal and other third-party costs associated with obtaining commitments for financing that result in a closing of such financings for the Company. These costs are amortized into earnings through interest expense over the terms of the respective agreements. Costs incurred in seeking financing transactions that do not close are expensed in the period in which it is determined that the financing will not close. Goodwill and Other Intangibles Goodwill represents the excess of the purchase price over the fair value of net tangible and identifiable intangible assets of acquired businesses. Indefinite-lived intangibles include trademarks and trade names. Goodwill and intangible assets deemed to have indefinite lives are not amortized, but are subject to impairment tests at least annually. The Company reviews the carrying amounts of goodwill and indefinite-lived intangible assets by reporting unit at least annually, or when indicators of impairment are present, to determine if such assets may be impaired. If the carrying amounts of these assets are not recoverable based upon discounted cash flow and market approach analyses, the carrying amounts of such assets are reduced by the estimated difference between the carrying values and estimated fair values. The Company includes assumptions about expected future operating performance as part of a discounted cash flow analysis to estimate fair value. If the carrying value of these assets is not recoverable, based on the discounted cash flow analysis, management performs the next step, which compares the fair value of the reporting unit to the carrying value of the tangible and intangible net assets of the reporting units. Goodwill is considered impaired if the recorded value of the tangible and intangible net assets exceeds the fair value of the reporting unit. The Company may first assess qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying value. The Company would not be required to quantitatively determine the fair value of the indefinite-lived intangible unless the Company determines, based on the qualitative assessment, that it is more likely than not that its fair value is less than the carrying value. The Company may skip the qualitative assessment and quantitatively test indefinite-lived intangibles by comparison of the individual carrying values to the fair value. Future cash flows of the individual indefinite-lived intangible assets are used to measure their fair value after consideration by management of certain assumptions, such as forecasted growth rates and cost of capital, which are derived from internal projections and operating plans. The Company performs its annual testing for goodwill and indefinite-lived intangible asset impairment at the beginning of the fourth quarter of the fiscal year for all reporting units. See Note 4 to the consolidated financial statements for information related to the results of the Company's annual test. Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or an asset group may not be recoverable. Each impairment test is based on a comparison of the carrying amount of the asset or asset group to the future undiscounted net cash flows expected to be generated by the asset or asset group. If such assets are considered to be impaired, the impairment amount to be recognized is the amount by which the carrying value of the assets exceeds their fair value. See Note 16 to the consolidated financial statements for information related to long-lived assets that were determined to be impaired. Retirement Benefits The determination of the obligation and expense for retirement benefits is dependent on the selection of certain actuarial assumptions used in calculating such amounts. These assumptions include, among others, the discount rate, expected long-term rate of return on plan assets, mortality rates and rates of increase in compensation. These assumptions are reviewed with the Company’s actuaries and updated annually based on relevant external and internal factors and information, including, but not limited to, long-term expected asset returns, rates of termination, regulatory requirements and plan changes. See Note 12 to the consolidated financial statements for additional information. The Company has elected to measure its defined benefit plan assets and obligations as of December 31^st of each year, regardless of the Company's actual fiscal year end date, which is the Saturday nearest to December 31. Income Taxes The provision for income taxes is based on the geographic dispersion of the earnings reported in the consolidated financial statements. A deferred income tax asset or liability is determined by applying currently-enacted tax laws and rates to the cumulative temporary differences between the carrying values of assets and liabilities for financial statement and income tax purposes. The Company records an increase in liabilities for income tax accruals associated with tax benefits claimed on tax returns but not recognized for financial statement purposes (unrecognized tax benefits). The Company recognizes interest and penalties related to unrecognized tax benefits through interest expense and income tax expense, respectively. Foreign Currency For most of the Company’s international subsidiaries, the local currency is the functional currency. Assets and liabilities of these subsidiaries are translated into U.S. dollars at the year-end exchange rate. Operating statement amounts are translated at average exchange rates for each period. The cumulative translation adjustments resulting from changes in exchange rates are included in the consolidated balance sheets as a component of accumulated other comprehensive income (loss) in stockholders’ equity. Transaction gains and losses are included in the consolidated statements of operations and were not material for fiscal years 2016, 2015 and 2014.

New Accounting Standards [Text Block]

NEW ACCOUNTING STANDARDS

The Financial Accounting Standards Board (“FASB”) issued the following Accounting Standards Updates (“ASU”) that have been adopted by the Company during fiscal 2016. The following is a summary of the effect of adoption of these new standards.



Standard	Description	Effect on the Financial Statements or Other Significant Matters
ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period	Requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant-date fair value of the award.	Did not have a material impact on its existing stock-based compensation plans.
ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern	Requires that an entity’s management evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued.	Did not have a significant impact on its quarterly reporting process.



Standard	Description	Effect on the Financial Statements or Other Significant Matters
ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs and ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements	Requires that debt issuance costs be presented in the balance sheet as a deduction from the carrying amount of the debt. Allows an entity to present debt issuance costs associated with a revolving line of credit arrangement as an asset, regardless of whether a balance is outstanding. Does not affect the recognition and measurement guidance for debt issuance costs.	Resulted in the reclassification of $10.2 million of deferred financing costs associated with the Company’s long-term debt from deferred financing costs to long-term debt as of January 2, 2016. In accordance with ASU 2015-15, the Company elected to continue to present its debt issuance costs related to its revolving line of credit as an asset. Due to the adoption of this standard, these deferred financing costs are included in other noncurrent assets. The prior period disclosures have been restated to conform to the current year presentation. The new standards did not affect the Company’s results of operations or cash flows.
ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments	Provides guidance for how certain cash receipts and cash payments should be presented and classified in the statement of cash flows, including debt prepayment or extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of corporate-owned life insurance policies, and distributions received from equity method investees.	Did not have a material impact on its existing cash flows presentation.

The FASB has issued the following ASUs that have not yet been adopted by the Company. The following is a summary of the planned adoption period and anticipated impact of adopting these new standards.



Standard	Description	Planned Period of Adoption	Effect on the Financial Statements or Other Significant Matters
ASU 2014-09, Revenue from Contracts with Customers (as amended by ASUs 2015-04, 2016-08, 2016-10 and 2016-12)	The core principle of the guidance is that an entity 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. The guidance also amends the required disclosures of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.	Q1 2018	The Company does not expect the adoption of the new standard to have a significant impact on its consolidated financial position, results of operations or cash flows. The effect on results is not expected to be material because the Company’s analysis of contracts under the new revenue recognition standard supports the recognition of revenue at a point in time for the majority of contracts, which is consistent with the current revenue recognition model. Revenue on the majority of contracts will continue to be recognized at a point in time because of the distinct transfer of control to the customer.
ASU 2015-11, Simplifying the Measurement of Inventory	Requires that an entity measure inventory at the lower of cost and net realizable value. This ASU does not apply to inventory measured using last-in, first-out.	Q1 2017	The Company does not expect the new standard to have a significant impact on its consolidated financial position, results of operations or cash flows.
ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities	Enhances the reporting model for financial instruments to provide users of financial statements with more decision-useful information. This ASU addresses certain aspects of recognition, measurement, presentation and disclosure of financial statements.	Q1 2018	The Company is evaluating the impacts of the new standard on its consolidated financial statements.



Standard	Description	Planned Period of Adoption	Effect on the Financial Statements or Other Significant Matters
ASU 2016-02, Leases	The core principle is that a lessee shall recognize a lease asset and lease liability in its statement of financial position. A lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term.	Q1 2019	The Company is evaluating the impacts of the new standard on its existing leases.
ASU 2016-05, Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships	Clarifies that the novation of a derivative contract (i.e., a change in the counterparty) in a hedge accounting relationship does not, in and of itself, require dedesignation of that hedge accounting relationship, provided that all other hedge accounting criteria continue to be met.	Q1 2017	The Company does not expect the new standard to have a significant impact on its consolidated financial position, results of operations or cash flows.
ASU 2016-09, Improvements to Employee Share-Based Payment Accounting	Seeks to provide simplification to issues of share-based payment awards in relation to income tax consequences, forfeitures, classification of awards as either equity or liabilities and classification on the statement of cash flows.	Q1 2017	The adoption of the new standard in fiscal 2017 is not expected to have a significant impact on the Company’s results of operations and cash flows as the income tax effects of its share-based payment awards will be recognized as a component of income tax expense, instead of as a component of additional paid-in capital.
ASU 2016-13, Measurement of Credit Losses on Financial Instruments	Seeks to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date by replacing the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.	Q1 2020	The Company is evaluating the impacts of the new standard on its existing financial instruments, including trade receivables.

Earnings Per Share [Abstract]

EARNINGS PER SHARE

The Company calculates earnings per share in accordance with FASB ASC Topic 260, Earnings Per Share (“ASC 260”). ASC 260 addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting, and, therefore, need to be included in the earnings allocation in computing earnings per share under the two-class method. Under the guidance in ASC 260, the Company’s unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are participating securities and must be included in the computation of earnings per share pursuant to the two-class method.

The following table sets forth the computation of basic and diluted earnings per share:



	Fiscal Year
(In millions, except per share data)	2016			2015			2014
Numerator:
Net earnings attributable to Wolverine World Wide, Inc.	$	87.7		$	122.8		$	133.1
Adjustment for earnings allocated to nonvested restricted common stock	(2.1		)	(2.8		)	(2.9		)
Net earnings used to calculate basic earnings per share	85.6			120.0			130.2
Adjustment for earnings reallocated to nonvested restricted common stock	0.1			0.1			0.1
Net earnings used to calculate diluted earnings per share	$	85.7		$	120.1		$	130.3

Shares used to calculate basic earnings per share	95.3			98.6			98.2
Effect of dilutive stock options	0.9			1.4			1.9
Shares used to calculate diluted earnings per share	96.2			100.0			100.1
Net earnings per share:
Basic	$	0.90		$	1.22		$	1.33
Diluted	$	0.89		$	1.20		$	1.30

Options granted to purchase 3,100,328 shares of common stock in fiscal 2016, 2,264,711 shares in fiscal 2015 and 1,116,576 shares in fiscal 2014 have not been included in the denominator for the computation of diluted earnings per share for each of those fiscal years because they were anti-dilutive.

The Company has 2,000,000 authorized shares of $1 par value preferred stock, none of which was issued or outstanding as of December 31, 2016 or January 2, 2016. The Company has designated 150,000 shares of preferred stock as Series A junior participating preferred stock and 500,000 shares of preferred stock as Series B junior participating preferred stock for possible future issuance.

The Company’s Board of Directors approved a common stock repurchase program on February 11, 2014. This program, which was terminated on August 8, 2016, authorized the repurchase of up to $200.0 million of common stock. On August 8, 2016, the Company's Board of Directors approved a new common stock repurchase program that authorizes the repurchase of up to $300.0 million in common stock over a four-year period, although the annual amount of any stock repurchases are restricted under the terms of the Company's Credit Agreement. The Company repurchased $61.9 million, $92.6 million and $0 of Company common stock in fiscal years 2016, 2015 and 2014, respectively, under stock repurchase plans. In addition to the stock repurchase program activity, the Company acquired $4.9 million, $7.7 million and $10.5 million of shares in fiscal years 2016, 2015 and 2014, respectively, in connection with employee transactions related to stock incentive plans.

Goodwill and Intangible Assets Disclosure [Text Block]

GOODWILL AND OTHER INTANGIBLE ASSETS

The changes during fiscal years 2016 and 2015 in the carrying amount of goodwill and indefinite-lived intangibles, which comprises trademarks and trade names, is as follows:



(In millions)	Goodwill			Indefinite-lived intangibles			Total
Balance at January 3, 2015	$	438.8		$	690.5		$	1,129.3
Impairment	—			(5.1		)	(5.1		)
Foreign currency translation effects	(9.7		)	—			(9.7		)
Balance at January 2, 2016	$	429.1		$	685.4		$	1,114.5
Purchase of intangibles	—			0.2			0.2
Sale of a business	(2.3		)	—			(2.3		)
Impairment	—			(7.1		)	(7.1		)
Foreign currency translation effects	(2.5		)	—			(2.5		)
Balance at December 31, 2016	$	424.3		$	678.5		$	1,102.8

In the fourth quarter of fiscal 2016, as a result of its annual impairment testing, the Company recorded a $7.1 million impairment charge for the Stride Rite^® trade name. The results of our indefinite-lived intangible impairment test based on the Company's outlook for future operating results continues to support the book value of the Sperry^® trade name. If the operating results for Stride Rite^® and Sperry^® were to decline in future periods, the Company may record a non-cash indefinite-lived intangible asset impairment charge. The carrying value of the Company’s Stride Rite^® and Sperry^® trade name indefinite-lived intangible assets was $7.9 million and $586.8 million, respectively, as of December 31, 2016.

In the second quarter of fiscal 2015, the Company recorded a $2.6 million impairment charge for the Cushe^® trade name, due to the decision to wind-down operations of the Cushe^® brand. In the fourth quarter of fiscal 2015, as a result of its annual impairment testing, the Company recorded a $2.5 million impairment charge for the Stride Rite^® trade name.

During fiscal 2016, the Company sold a non-core business within the Multi-Brand Group operating segment, which included an allocation of goodwill for the brand.

The Company did not recognize any impairment charges for goodwill during fiscal years 2016 or 2015 or for goodwill or indefinite-lived intangible assets during fiscal 2014, as the annual impairment testing indicated that all reporting unit goodwill and indefinite-lived intangible asset fair values exceeded their respective carrying values.

Amortizable intangible assets are amortized using the straight-line method over their estimated useful lives. They consist primarily of customer relationships, licensing arrangements and developed product technology. The combined gross carrying value and accumulated amortization for these amortizable intangibles is as follows:



	December 31, 2016
(In millions)	Average remaining life (years)	Gross carrying value		Accumulated amortization		Net
Customer relationships	16	$	100.5	$	21.6	$	78.9
Licensing arrangements	1	28.8		27.6		1.2
Developed product technology	1	14.9		12.7		2.2
Other	3	11.4		9.9		1.5
Total		$	155.6	$	71.8	$	83.8



	January 2, 2016
(In millions)	Average remaining life (years)	Gross carrying value		Accumulated amortization		Net
Customer relationships	17	$	100.5	$	16.7	$	83.8

Other	3	11.2		9.6		1.6
Total		$	155.4	$	58.1	$	97.3

Amortization expense for other intangible assets was $14.0 million, $15.6 million and $15.7 million for fiscal years 2016, 2015 and 2014, respectively. Estimated aggregate amortization expense for such intangibles for the fiscal years subsequent to December 31, 2016 is as follows:



(In millions)	2017		2018		2019		2020		2021
Amortization expense	$	9.0	$	5.5	$	5.3	$	5.2	$	5.0

Accounts Receivable [Abstract]

ACCOUNTS RECEIVABLE

The Company has an agreement with a financial institution to sell selected trade accounts receivable on a recurring, nonrecourse basis that expires in the fourth quarter of fiscal 2017. Under the agreement, up to $200.0 million of accounts receivable may be sold to the financial institution and remain outstanding at any point in time. After the sale, the Company does not retain any interests in the accounts receivable and removes them from its consolidated balance sheet, but continues to service and collect the outstanding accounts receivable on behalf of the financial institution. The Company recognizes a servicing asset or servicing liability, initially measured at fair value, each time it undertakes an obligation to service the accounts receivable under the agreement. The fair value of this obligation resulted in a nominal servicing liability for all periods presented. For receivables sold under the agreement, 90% of the stated amount is paid for in cash to the Company at the time of sale, with the remainder paid to the Company at the completion of the collection process. The following is a summary of the stated amount of accounts receivable that was sold as well as fees charged by the financial institution.



	Fiscal Year
(In millions)	2016		2015		2014
Accounts receivable sold	$	614.9	$	657.4	$	72.8
Fees charged	1.7		1.4		0.1

The fees are recorded in other expense. Net proceeds of this program are classified in operating activities in the consolidated condensed statements of cash flows. This program reduced the Company's accounts receivable by $81.1 million and $77.6 million as of December 31, 2016 and January 2, 2016, respectively.

DEBT

Total debt consists of the following obligations:



(In millions)	December 31, 2016			January 2, 2016
Term Loan A, due July 13, 2020	$	575.6		$	444.4
Senior Notes, 5.000% interest, due September 1, 2026	250.0			—

Capital lease obligation	0.5			0.6
Unamortized debt issuance costs	(8.3		)	(10.2		)
Total debt	$	820.7		$	809.8

On September 15, 2016, the Company amended its credit agreement (as amended, the "Credit Agreement"). The Credit Agreement provided a $588.8 million term loan facility (“Term Loan A”) and a $600.0 million revolving credit facility (the “Revolving Credit Facility”), both with maturity dates of July 13, 2020. The Credit Agreement’s debt capacity is limited to an aggregate debt amount (including outstanding term loan principal and revolver commitment amounts in addition to permitted incremental debt) not to exceed $1,750.0 million, unless certain specified conditions set forth in the Credit Agreement are met.

The Revolving Credit Facility allows the Company to borrow up to an aggregate amount of $600.0 million, which includes a $200.0 million foreign currency subfacility under which borrowings may be made, subject to certain conditions, in Canadian dollars, British pounds, euros, Hong Kong dollars, Swedish kronor, Swiss francs and such additional currencies as are determined in accordance with the Credit Agreement. The Revolving Credit Facility also includes a $50.0 million swingline subfacility and a $50.0 million letter of credit subfacility. The Company had outstanding letters of credit under the Revolving Credit Facility of $2.6 million and $3.8 million as of December 31, 2016 and January 2, 2016, respectively. These outstanding letters of credit reduce the borrowing capacity under the Revolving Credit Facility.

The interest rates applicable to amounts outstanding under Term Loan A and to U.S. dollar denominated amounts outstanding under the Revolving Credit Facility will be, at the Company’s option, either (1) the Alternate Base Rate plus an Applicable Margin as determined by the Company’s Consolidated Leverage Ratio, within a range of 0.25% to 1.00%, or (2) the Eurocurrency Rate plus an Applicable Margin as determined by the Company’s Consolidated Leverage Ratio, within a range of 1.25% to 2.00% (all capitalized terms used in this sentence are as defined in the Credit Agreement). The Company has two interest rate swap arrangements that reduce the Company’s exposure to fluctuations in interest rates on its variable rate debt. At December 31, 2016, Term Loan A had a weighted-average interest rate of 2.85%.

The obligations of the Company pursuant to the Credit Agreement are guaranteed by substantially all of the Company’s material domestic subsidiaries and secured by substantially all of the personal and real property of the Company and its material domestic subsidiaries, subject to certain exceptions.

The Credit Agreement also contains certain affirmative and negative covenants, including covenants that limit the ability of the Company and its Restricted Subsidiaries to, among other things: incur or guarantee indebtedness; incur liens; pay dividends or repurchase stock; enter into transactions with affiliates; consummate asset sales, acquisitions or mergers; prepay certain other indebtedness; or make investments, as well as covenants restricting the activities of certain foreign subsidiaries of the Company that hold intellectual property related assets. Further, the Credit Agreement requires compliance with the following financial covenants: a maximum Consolidated Leverage Ratio; a maximum Consolidated Secured Leverage Ratio; and a minimum Consolidated Interest Coverage Ratio (all capitalized terms used in this paragraph are as defined in the Credit Agreement). As of December 31, 2016, the Company was in compliance with all covenants and performance ratios under the Credit Agreement.

On August 30, 2016, the Company issued $250.0 million of senior notes that are due on September 1, 2026 (the “Senior Notes”). The Senior Notes bear interest at 5.000% with the related interest payments due semi-annually. The Senior Notes are guaranteed by substantially all of the Company’s domestic subsidiaries.

The Company had $375.0 million of senior notes outstanding that were able to be traded in the public market (the “Public Bonds”) that were due on October 15, 2020. On September 15, 2016, the Company redeemed the Public Bonds using the proceeds of the Senior Note issuance and the additional borrowings on Term Loan A. Due to the early redemption of the Public Bonds, the Company incurred debt extinguishment costs of $17.4 million in fiscal 2016. This amount includes a $13.1 million early redemption premium and the write-off of the unamortized balance of the deferred financing fees related to the original debt issuance.

The Company has various foreign revolving credit facilities with aggregate available borrowings of $9.0 million that are uncommitted and, therefore, each borrowing against the applicable facility is subject to approval by the lender. Borrowings against these facilities were $1.8 million and $0 as of December 31, 2016 and January 2, 2016, respectively.

The Company has a capital lease obligation with payments scheduled to continue through February 2022.

The Company included in interest expense the amortization of deferred financing costs of $3.1 million, $3.7 million and $4.2 million in fiscal years 2016, 2015 and 2014, respectively.

Annual maturities of debt, including capital leases, for the fiscal years subsequent to December 31, 2016 are as follows:



(In millions)	2017		2018		2019		2020		2021		Thereafter
Annual maturities of debt	$	40.4	$	52.7	$	60.1	$	425.7	$	0.1	$	250.0

Financial Instruments and Risk Management

FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

The Company follows FASB ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”), which provides a consistent definition of fair value, focuses on exit price, prioritizes the use of market-based inputs over entity-specific inputs for measuring fair value and establishes a three-tier hierarchy for fair value measurements. ASC 820 requires fair value measurements to be classified and disclosed in one of the following three categories:



Level 1:		Fair value is measured using quoted prices (unadjusted) in active markets for identical assets and liabilities.

Level 2:		Fair value is measured using either direct or indirect inputs, other than quoted prices included within Level 1, which are observable for similar assets or liabilities.

Level 3:		Fair value is measured using valuation techniques in which one or more significant inputs are unobservable.

The Company’s financial instruments consist of cash and cash equivalents, accounts and notes receivable, accounts payable, foreign currency forward exchange contracts, interest rate swap arrangements, borrowings under revolving credit agreements and long-term debt. The carrying amount of the Company’s financial instruments is historical cost, which approximates fair value, except for the interest rate swaps and foreign currency forward exchange contracts, which are carried at fair value. The carrying value and the fair value of the Company’s debt, excluding capital leases, are as follows:



(In millions)	December 31, 2016		January 2, 2016
Carrying value	$	820.2	$	809.2
Fair value	827.6		836.3

The fair value of the fixed rate debt was based on third-party quotes (Level 2). The fair value of the variable rate debt was calculated by discounting the future cash flows to its present value using a discount rate based on the risk-free rate of the same maturity (Level 3).

The Company follows ASC 815, which is intended to improve transparency in financial reporting and requires that all derivative instruments be recorded on the consolidated balance sheets at fair value by establishing criteria for designation and effectiveness of hedging relationships. The Company utilizes foreign currency forward exchange contracts to manage the volatility associated primarily with U.S. dollar inventory purchases made by non-U.S. wholesale operations in the normal course of business. These foreign currency forward exchange hedge contracts extend out to a maximum of 356 days and 349 days, as of December 31, 2016 and January 2, 2016, respectively. The Company also utilizes foreign currency forward exchange contracts that are not designated as hedging instruments to manage foreign currency translation exposure. Foreign currency derivatives not designated as hedges are offset by foreign exchange gains or losses resulting from the underlying exposures of foreign currency denominated assets and liabilities.

The Company has two interest rate swap arrangements which exchange floating rate for fixed rate interest payments over the life of the agreements without the exchange of the underlying notional amounts. These derivative instruments, which, unless otherwise terminated, will mature on October 6, 2017 and July 13, 2020, and have been designated as cash flow hedges of the debt. The notional amounts of the interest rate swap arrangements are used to measure interest to be paid or received and do not represent the amount of exposure to credit loss. The Company does not hold or issue financial instruments for trading purposes.

The notional amounts of the Company’s derivative instruments are as follows:



(Dollars in millions)	December 31, 2016		January 2, 2016
Foreign exchange contracts:
Hedge contracts	$	169.2	$	192.6
Non-hedge contracts	2.1		23.2
Interest rate swaps	496.0		609.7

The following table sets forth financial assets and liabilities measured at fair value in the consolidated balance sheets and the respective pricing levels to which the fair value measurements are classified within the fair value hierarchy.



	Fair Value Measurements
	Quoted Prices With Other Observable Inputs (Level 2)

Financial liabilities:
Foreign exchange contracts - hedge	$	(0.3	)	$	—
Foreign exchange contracts - non-hedge	—			(0.1		)
Interest rate swaps	(5.3		)	(3.9		)

The fair value of the foreign currency forward exchange contracts represents the estimated receipts or payments necessary to terminate the contracts. Hedge effectiveness is evaluated by the hypothetical derivative method. Any hedge ineffectiveness is reported within the Cost of goods sold line item in the consolidated statements of operations. Hedge ineffectiveness was not material to the Company’s consolidated financial statements for fiscal years 2016, 2015 and 2014. If, in the future, the foreign exchange contracts are determined to be ineffective hedges or terminated before their contractual termination dates, the Company would be required to reclassify into earnings all or a portion of the unrealized amounts related to the cash flow hedges that are currently included in accumulated other comprehensive loss within stockholders’ equity.

The differential paid or received on the interest rate swap arrangements is recognized as interest expense. In accordance with ASC 815, the Company has formally documented the relationship between the interest rate swaps and the variable rate borrowings, as well as its risk management objective and strategy for undertaking the hedge transaction. This process included linking the derivative to the specific liability or asset on the balance sheet. The Company also assessed at the hedges’ inception, and continues to assess on an ongoing basis, whether the derivatives used in the hedging transaction are highly effective in offsetting changes in the cash flows of the hedged item. The effective portion of unrealized gains (losses) is deferred as a component of accumulated other comprehensive loss and will be recognized in earnings at the time the hedged item affects earnings. Any ineffective portion of the change in fair value will be immediately recognized in earnings.

Stock-Based Compensation

Stock-Based Compensation

STOCK-BASED COMPENSATION

The Company accounts for stock-based compensation in accordance with the fair value recognition provisions of ASC 718. The Company recognized compensation expense of $22.8 million, $18.7 million and $25.1 million and related income tax benefits of $7.9 million, $6.1 million and $8.4 million for grants under its stock-based compensation plans in the statements of operations for fiscal years 2016, 2015 and 2014, respectively.

Stock-based compensation expense recognized in the consolidated statements of operations for fiscal years 2016, 2015 and 2014 was based on awards ultimately expected to vest and, as such, was reduced for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on historical experience.

As of December 31, 2016, the Company had 6,126,194 stock incentive units (stock options, stock appreciation rights, restricted stock, restricted stock units and common stock) available for issuance. Each option or stock appreciation right granted counts as 1.0 stock incentive unit and all other awards granted, including restricted stock, count as 2.6 stock incentive units. Options granted under each plan have an exercise price equal to the fair market value of the underlying stock on the grant date, expire no later than ten years from the grant date and generally vest over three years. Restricted stock issued under these plans is subject to certain restrictions, including a prohibition against any sale, transfer or other disposition by the officer or employee during the vesting period (except for certain transfers for estate planning purposes for certain officers), and a requirement to forfeit all or a certain portion of the award upon certain terminations of employment or upon failure to achieve performance criteria in certain instances. These restrictions typically lapse over a three- to five-year period from the date of the award. The Company has elected to recognize expense for these stock-based incentive plans ratably over the vesting term on a straight-line basis. Certain option and restricted share awards provide for accelerated vesting under various scenarios, including retirement and upon a change in control of the Company. With regard to acceleration of vesting upon retirement, employees of eligible retirement age are vested in accordance with plan provisions and applicable stock option and restricted stock agreements. The Company issues shares to plan participants upon exercise or vesting of stock-based incentive awards from either authorized, but unissued, shares or treasury shares.

The Board of Directors awards an annual grant of performance share awards to certain plan participants. The number of performance-based shares that will be earned (and eligible to vest) during the performance period will depend on the Company’s level of success in achieving two specifically identified performance targets. Any portion of the performance shares that are not earned by the end of the three-year measurement period will be forfeited. The final determination of the number of shares to be issued in respect to an award is determined by the Compensation Committee of the Company’s Board of Directors.

The Company estimated the fair value of employee stock options on the date of grant using the Black-Scholes-Merton formula. The estimated weighted-average fair value for each option granted was $3.36, $6.35 and $6.20 per share for fiscal years 2016, 2015 and 2014, respectively, with the following weighted-average assumptions.

⁽¹⁾	Based on historical volatility of the Company’s common stock. The expected volatility is based on the daily percentage change in the price of the stock over the four years prior to the grant.


⁽²⁾	Represents the U.S. Treasury yield curve in effect for the expected term of the option at the time of grant.


⁽³⁾	Represents the Company’s estimated cash dividend yield for the expected term.


⁽⁴⁾	Represents the period of time that options granted are expected to be outstanding. As part of the determination of the expected term, the Company concluded that all employee groups exhibit similar exercise and post-vesting termination behavior.

A summary of the stock option transactions is as follows:

The total pretax intrinsic value of options exercised during fiscal years 2016, 2015 and 2014 was $4.0 million, $14.5 million and $10.3 million, respectively. As of December 31, 2016, there was $4.8 million of unrecognized compensation expense related to stock option grants expected to be recognized over a weighted-average period of 1.4 years. As of January 2, 2016 and January 3, 2015, there was $4.6 million and $4.6 million, respectively, of unrecognized compensation expense related to stock option awards expected to be recognized over a weighted-average period of 1.2 years and 1.2 years, respectively.

The aggregate intrinsic value in the preceding table represents the total pretax intrinsic value, based on the Company’s closing stock price as of each fiscal year end, which would have been received by the option holders had all option holders exercised options, where the market price of the Company's stock was above the strike price ("in-the-money"), as of that date. The total number of in-the-money options exercisable as of December 31, 2016, based on the Company’s closing stock price of 21.95, was 3,546,676 and the weighted-average exercise price was $16.81. As of January 2, 2016, 1,811,921 outstanding options were exercisable and in-the-money and the weighted-average exercise price was $11.94.

Retirement Plans

RETIREMENT PLANS

The Company has three non-contributory, defined benefit pension plans that provide retirement benefits to less than half of its domestic employees. The Company’s principal defined benefit pension plan provides benefits based on the employee’s years of service and final average earnings. Effective January 1, 2013, the Company closed this plan to new participants. The Company’s second plan provides benefits at a fixed rate per year of service for certain employees under a collective bargaining arrangement. The Company’s third non-contributory defined benefit pension plan, which no longer accrues future benefits, covers certain eligible PLG associates. Prior to the freezing of that plan, eligible PLG participants accrued pension benefits at a fixed unit rate based on the participant’s service and/or compensation.

The Company has a Supplemental Executive Retirement Plan (the “SERP”) for certain current and former employees that entitles a participating employee to receive payments from the Company following retirement based on the employee’s years of service and final average earnings (as defined in the SERP). Under the SERP, the employees can elect early retirement with a corresponding reduction in benefits. The Company also has individual deferred compensation agreements with certain former employees that entitle those employees to receive payments from the Company for a period of time that generally extends 15 to 18 years following retirement. The Company maintains life insurance policies with a cash surrender value of $56.6 million at December 31, 2016 and $64.6 million at January 2, 2016 that are intended to partially fund deferred compensation benefits under the SERP and deferred compensation agreements.

The Company has two defined contribution 401(k) plans covering substantially all domestic employees that provide for Company contributions based on earnings. The Company recognized expense for its defined contribution plans of $4.0 million, $4.6 million and $4.7 million in fiscal years 2016, 2015 and 2014, respectively.

The Company has certain defined contribution plans at foreign subsidiaries. Contributions to these plans were $1.1 million, $1.5 million and $1.2 million in fiscal years 2016, 2015 and 2014, respectively. The Company also has a benefit plan at a foreign location that provides for retirement benefits based on years of service. The obligation recorded under this plan was $1.1 million at December 31, 2016 and $1.9 million at January 2, 2016 and was recognized as a deferred compensation liability on the consolidated balance sheets.

The following summarizes the status of and changes in the Company’s assets and related obligations for its pension plans (which include the Company’s defined benefit pension plans and the SERP) for the fiscal years 2016 and 2015:

Amounts recognized in accumulated other comprehensive loss:
Unrecognized net actuarial loss (amounts net of tax: $(30.4) and $(12.7))	$	(45.3	)	$	(18.2	)
Unrecognized prior service cost (amounts net of tax: $0 and $(0.1))	—			(0.1		)
Net amount recognized	$	(45.3	)	$	(18.3	)
Funded status of pension plans and SERP (supplemental):
Funded status of qualified defined benefit plans and SERP	$	(145.6	)	$	(112.0	)
Nonqualified trust assets (cash surrender value of life insurance) recorded in other assets and intended to satisfy the projected benefit obligation of unfunded SERP obligations	50.1			58.4
Net funded status of pension plans and SERP (supplemental)	$	(95.5	)	$	(53.6	)

The accumulated benefit obligations for all defined benefit pension plans and the SERP were $396.3 million at December 31, 2016 and $375.5 million at January 2, 2016.

The following is a summary of net pension and SERP expense recognized by the Company:



	Fiscal Year
(In millions)	2016			2015			2014
Service cost pertaining to benefits earned during the year	$	6.5		$	9.0		$	7.2
Interest cost on projected benefit obligations	19.1			18.5			20.3
Expected return on pension assets	(20.1		)	(20.5		)	(22.1		)
Net amortization loss	5.0			20.9			7.5
Settlement gain	(0.1		)	—			(1.0		)
Net pension expense	$	10.4		$	27.9		$	11.9
Less: SERP expense	5.8			7.8			7.6
Qualified defined benefit pension plans expense	$	4.6		$	20.1		$	4.3

The actuarial loss included in accumulated other comprehensive loss and expected to be recognized in net periodic pension expense during 2017 is $9.8 million.

The weighted-average actuarial assumptions used to determine the benefit obligation amounts and the net periodic benefit cost for the Company’s pension and post-retirement plans are as follows:



	Fiscal Year
	2016	2015
Weighted-average assumptions used to determine benefit obligations at fiscal year-end:
Discount rate	4.35%	5.00%
Rate of compensation increase - pension	4.85%	4.85%
Rate of compensation increase - SERP	7.00%	7.00%
Weighted average assumptions used to determine net periodic benefit cost for the years ended:
Discount rate	5.00%	4.37%
Expected long-term rate of return on plan assets	7.25%	7.50%
Rate of compensation increase - pension	4.85%	4.85%
Rate of compensation increase - SERP	7.00%	7.00%

Unrecognized net actuarial losses exceeding certain corridors are amortized over one of two amortization periods, based on each plan's election. The amortization period is either a five-year period, unless the minimum amortization method based on average remaining service periods produces a higher amortization; or, over the average remaining service period of participants expected to receive benefits. The Company utilizes a bond matching calculation to determine the discount rate. A hypothetical bond portfolio is created based on a presumed purchase of high-quality corporate bonds with maturities that match the plan’s expected future cash outflows. The discount rate is the resulting yield of the hypothetical bond portfolio. The discount rate is used in the calculation of the year-end pension liability and service cost for the subsequent year.

The long-term rate of return is based on overall market expectations for a balanced portfolio with an asset mix similar to the Company’s, utilizing historic returns for broad market and fixed income indices. The Company’s investment policy for plan assets uses a blended approach of U.S. and foreign equities combined with U.S. fixed income investments. The target investment allocations as of December 31, 2016 were 65% in equity securities and 35% in fixed income securities. Within the equity and fixed income classifications, the investments are diversified. The Company’s asset allocations by asset category and fair value measurement are as follows:



	December 31, 2016

The valuation allowance for deferred income tax assets as of December 31, 2016 and January 2, 2016 was $11.5 million and $9.5 million, respectively. The net change in the total valuation allowance for fiscal years 2016 and 2015 was $(2.0) million and $1.0 million, respectively. The valuation allowance for the prior year was primarily related to foreign net operating loss carryforwards, tax credit carryforwards in foreign jurisdictions and a capital loss carryforward in the U.S. that, in the judgment of management, are not more likely than not to be realized. In addition to the prior year’s foreign net operating loss and foreign tax credit carryforwards, the current year valuation allowance also includes U.S. state and local net operating loss carryforwards as well as a valuation allowance against state deferred tax assets for certain U.S. legal entities. The U.S. capital loss carryforward period expired in the current year and the capital loss is therefore no longer included in the valuation allowance. The ultimate realization of the deferred tax assets depends on the generation of future taxable income in foreign jurisdictions as well as state and local tax jurisdictions. The current year change in the valuation allowance was comprised of an increase against the state deferred tax assets of $4.9 million and an increase related to state net operating loss carryforward of $1.1 million, partially offset by a decrease relating to the expiration of a capital loss carryforward of $2.7 million, a decrease related to an audit adjustment in foreign net operating loss of $0.8 million and a net decrease relating to the foreign net operating losses and foreign tax credits of $0.5 million.

At December 31, 2016, the Company had foreign net operating loss carryforwards of $26.5 million, which have expiration periods ranging from five years to an unlimited term during which they are available to offset future foreign taxable income. The Company had U.S. state net operating loss carryforwards of $51.3 million, which have expiration periods ranging from six years to twenty years during which they are available to offset future state taxable income. The Company also had tax credit carryforwards in foreign jurisdictions of $2.3 million, which are available for an unlimited carryforward period to offset future foreign taxes. The Company also had a U.S. capital loss carryforward expire in the current year of $7.6 million.

The following table summarizes the activity related to the Company’s unrecognized tax benefits:



	Fiscal Year
(In millions)	2016			2015
Beginning balance	$	8.7		$	8.6
Increases related to current year tax positions	1.4			1.1
Decreases related to prior year positions	(1.0		)	(0.6		)
Decrease due to lapse of statute	(0.2		)	(0.4		)
Ending balance	$	8.9		$	8.7

The portion of the unrecognized tax benefits that, if recognized currently, would reduce the annual effective tax rate was $7.8 million as of December 31, 2016 and $7.7 million as of January 2, 2016. The Company recognizes interest and penalties related to unrecognized tax benefits through interest expense and income tax expense, respectively. Interest accrued related to unrecognized tax benefits was $2.9 million as of December 31, 2016 and $2.8 million as of January 2, 2016.

The Company is subject to periodic audits by domestic and foreign tax authorities. Currently, the Company is undergoing routine periodic audits in both domestic and foreign tax jurisdictions. It is reasonably possible that the amounts of unrecognized tax benefits could change in the next 12 months as a result of the audits. However, any payment of tax is not expected to be significant to the consolidated financial statements.

For the majority of tax jurisdictions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2012.

The Company has not established a deferred tax liability on the amount of foreign unremitted earnings of $527.9 million at December 31, 2016. As of December 31, 2016, the Company had $369.8 million of cash and equivalents on hand, of which $227.8 million was held outside of the U.S. The Company intends to permanently reinvest these funds outside of the U.S., and current plans do not demonstrate a need to repatriate this cash to fund its U.S. operations. However, if these funds were repatriated, the Company would be required to accrue and pay applicable U.S. taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to various countries. It is not practicable to estimate the amount of the deferred tax liability associated with these unremitted earnings due to the complexity of the hypothetical calculation.

Litigation and Contingencies

LITIGATION AND CONTINGENCIES

The Company is involved in various environmental claims and other legal actions arising in the normal course of business. The environmental claims include sites where the U.S. Environmental Protection Agency has notified the Company that it is a potentially responsible party with respect to environmental remediation. These remediation claims are subject to ongoing environmental impact studies, assessment of remediation alternatives, allocation of costs between responsible parties and concurrence by regulatory authorities and have not yet advanced to a stage where the Company’s liability is fixed. However, after taking into consideration legal counsel’s evaluation of all actions and claims against the Company, it is management’s opinion that the outcome of these matters will not have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

The Company is involved in routine litigation incidental to its business and is a party to legal actions and claims, including, but not limited to, those related to employment and intellectual property. Some of the legal proceedings include claims for compensatory as well as punitive damages. While the final outcome of these matters cannot be predicted with certainty, considering, among other things, the meritorious legal defenses available and liabilities that have been recorded along with applicable insurance, it is management’s opinion that the outcome of these items will not have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

The Company has future minimum royalty and advertising obligations due under the terms of certain licenses held by the Company. These minimum future obligations for the fiscal years subsequent to December 31, 2016 are as follows:



(In millions)	2017		2018		2019		2020		2021		Thereafter
Minimum royalties	$	2.0	$	1.4	$	1.5	$	1.5	$	—	$	—
Minimum advertising	3.3		3.3		3.4		3.5		3.7		7.6

Minimum royalties are based on both fixed obligations and assumptions regarding the Consumer Price Index. Royalty obligations in excess of minimum requirements are based upon future sales levels. In accordance with these agreements, the Company incurred royalty expense of $2.0 million, $2.0 million and $2.3 million for fiscal years 2016, 2015 and 2014, respectively.

The terms of certain license agreements also require the Company to make advertising expenditures based on the level of sales. In accordance with these agreements, the Company incurred advertising expense of $3.2 million, $3.3 million and $4.1 million for fiscal years 2016, 2015 and 2014, respectively.

Business Segments

BUSINESS SEGMENTS

During the first quarter of fiscal 2016, the Company’s portfolio of brands was realigned into the following four operating segments, which the Company has determined to be reportable operating segments. All prior period disclosures have been restated to reflect these new reportable operating segments.


•	Wolverine Outdoor & Lifestyle Group, consisting of Merrell^® footwear and apparel, Cat^® footwear, Hush Puppies^® footwear and apparel, Chaco^® footwear, Sebago^® footwear and apparel and Cushe^® footwear;

•	Wolverine Multi-Brand Group, consisting of Stride Rite^® footwear and apparel and the Company's multi-brand consumer-direct businesses.

The reportable segments are engaged in designing, manufacturing, sourcing, marketing, licensing and distributing branded footwear, apparel and accessories. Reported revenue for the reportable operating segments includes revenue from the sale of branded footwear, apparel and accessories to third-party customers; revenue from third-party licensees and distributors; and revenue from the Company’s consumer-direct businesses.

The Company also reports “Other” and “Corporate” categories. The Other category consists of the Company’s leather marketing operations and sourcing operations that include third-party commission revenues. The Corporate category consists of unallocated corporate expenses, including restructuring and impairment costs. The Company’s operating segments are determined based on how the Company internally reports and evaluates financial information used to make operating decisions. The operating segment managers all report directly to the chief operating decision maker.

The accounting policies of each operating segment are the same as those described in the summary of significant accounting policies set forth in Note 1 to the consolidated financial statements.

Company management uses various financial measures to evaluate the performance of the reportable operating segments. The following is a summary of certain key financial measures for the respective fiscal periods indicated. All prior period amounts have been restated to reflect the new reportable operating segments.

The Company does not believe that it is dependent upon any single customer because no customer accounts for more than 10% of consolidated revenue in any year.

During fiscal 2016, the Company sourced approximately 98% of its footwear products from third-party suppliers located primarily in the Asia Pacific region. For fiscal 2016, the remainder was produced at Company-owned manufacturing facilities in the U.S. All apparel and accessories are sourced from third-party suppliers. While changes in suppliers could cause delays in manufacturing and a possible loss of sales, management believes that other suppliers could provide similar products on comparable terms.

The entire disclosure for reporting segments including data and tables. Reportable segments include those that meet any of the following quantitative thresholds a) it's reported revenue, including sales to external customers and intersegment sales or transfers is 10 percent or more of the combined revenue, internal and external, of all operating segments b) the absolute amount of its reported profit or loss is 10 percent or more of the greater, in absolute amount of 1) the combined reported profit of all operating segments that did not report a loss or 2) the combined reported loss of all operating segments that did report a loss c) its assets are 10 percent or more of the combined assets of all operating segments.

RESTRUCTURING ACTIVITIES

2016 Plan

On October 6, 2016, the Board of Directors of the Company approved a realignment of the Company’s consumer-direct operations . As a part of the 2016 Plan, the Company intends to close certain retail stores during fiscal 2017. The Company currently estimates pretax charges related to the 2016 Plan will range from $43.0 million to $49.0 million. The Company estimates it will record the remaining charges through the end of fiscal 2017. Once fully implemented, the Company expects annual pretax benefits of approximately $20.0 million as a result of the 2016 Plan. The Company closed 51 retail stores in connection with the 2016 Plan during fiscal 2016 .

Costs incurred related to the 2016 Plan have been recorded within the Corporate category. The cumulative costs incurred is $5.8 million, with $2.7 million recorded in the restructuring costs line item as a component of cost of goods sold, and $3.1 million recorded in the restructuring and impairment costs line item as a component of operating expenses. The following is a summary of the activity during fiscal 2016, with respect to a reserve established by the Company in connection with the 2016 Plan, by category of costs.

On October 4, 2013, the Board of Directors of the Company approved a plan to restructure the Company’s Dominican Republic manufacturing operations in a manner intended to lower the Company’s cost of goods sold, as described below (the “2013 Plan”). During the fourth quarter of fiscal 2013, the Company sold a manufacturing facility in the Dominican Republic and closed a second manufacturing facility. The Company no longer maintains any Company-owned manufacturing operations in the Dominican Republic. The Company recognized $7.6 million of restructuring costs in fiscal 2013 and restructuring costs of $1.0 million during fiscal 2014. The Company considers the 2013 Plan complete and does not expect to recognize any further costs. All costs incurred for the 2013 Plan have been recognized in the Company’s Corporate category and are included in the restructuring costs line item as a component of cost of goods sold in the consolidated statements of operations.

The following is a summary of the activity during fiscal 2014, with respect to a reserve established by the Company in connection with the 2013 Plan, by category of costs.

During fiscal 2016, the Company recorded restructuring costs of $13.9 million in connection with certain organizational changes made during fiscal 2016. The costs associated with these restructuring activities were recorded within the Company’s Corporate category included in the restructuring and impairment costs line item as a component of operating expenses in the consolidated condensed statements of operations and comprehensive income.

During fiscal 2015, the Company recorded restructuring and impairment costs of $4.2 million related to its decision to wind-down operations of its Cushe^® brand. These costs included $2.6 million related to indefinite-lived intangibles and $1.6 million in other restructuring costs. The Company recorded these costs within its Corporate category in the restructuring and impairment costs line item as a component of operating expenses in the consolidated condensed statements of operations and comprehensive income. During fiscal 2016, the Company recorded additional restructuring costs of $0.3 million related to the Cushe^® brand.

During fiscal 2014, the Company recorded an impairment of an equity method investment and reserved certain receivables within the Company’s international operations. The impairment and asset charge were determined to be other-than-temporary and the Company recorded a non-cash charge of $4.8 million within its corporate category included in the restructuring and impairment costs line item as a component of operating expenses in the consolidated statements of operations. During fiscal 2015, the Company recorded additional restructuring costs of $2.0 million related to its international operations.

During the fourth quarters of fiscal 2016 and 2015, the Company recorded impairment costs of $7.1 million and $2.5 million, respectively, related to indefinite-lived intangibles of its Stride Rite^® brand. The Company recorded these costs within its Corporate category in the restructuring and impairment costs line item as a component of operating expenses in the consolidated statements of operations.

The Company recorded impairment charges of $12.2 million and $11.6 million during fiscal 2016 and 2015, respectively, related to certain consumer-direct store assets where the estimated future cash flows did not support the net book value of the store assets. These costs were recorded within its corporate category in the restructuring and impairment costs line item as a component of operating expenses in the consolidated statements of operations.

Nonrecurring Fair Value Measurements

The following is a summary of assets and impairments that were measured at fair value on a nonrecurring basis.



	Fiscal 2016				Fiscal 2015
(In millions)	Fair Value		Impairment		Fair Value		Impairment
Property and equipment	$	0.7	$	12.4	$	1.8	$	17.0
Indefinite-lived intangibles	7.9		7.1		15.0		5.1

The property and equipment and indefinite-lived intangibles were valued using an income approach based on the discounted cash flows expected to be generated by the underlying assets (Level 3). See Note 10 to the consolidated financial statements for additional information on Level 3 fair value measurements.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Dec. 31, 2016
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Wolverine World Wide, Inc. is a leading designer, manufacturer and marketer of a broad range of quality casual footwear and apparel; performance outdoor and athletic footwear and apparel; children’s footwear, industrial work shoes, boots and apparel; and uniform shoes and boots. The Company’s portfolio of owned and licensed brands includes: Bates^®, Cat^®, Chaco^®, Harley-Davidson^®, Hush Puppies^®, HyTest^®, Keds^®, Merrell^®, Saucony^®, Sebago^®, Sperry^®, Stride Rite^® and Wolverine^®. Licensing and distribution arrangements with third parties extend the global reach of the Company’s brand portfolio. The Company also operates a consumer-direct division to market both its own brands and branded footwear and apparel from other manufacturers, as well as a leathers division that markets Wolverine Performance Leathers™.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Wolverine World Wide, Inc. and its majority-owned subsidiaries (collectively, the “Company”). All intercompany accounts and transactions have been eliminated in consolidation.
Fiscal Year	Fiscal Year The Company’s fiscal year is the 52- or 53-week period that ends on the Saturday nearest to December 31. Fiscal years 2016 and 2015 had 52 weeks and fiscal 2014 contained 53 weeks.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition Revenue is recognized on the sale of products manufactured or sourced by the Company when the related goods have been shipped, legal title has passed to the customer and collectability is reasonably assured. Revenue generated through licensees and distributors involving products bearing the Company’s trademarks is recognized as earned according to stated contractual terms upon either the purchase or shipment of branded products by licensees and distributors. Retail store revenue is recognized at time of sale. The Company records provisions for estimated sales returns and allowances at the time of sale based on historical rates of returns and allowances and specific identification of outstanding returns not yet received from customers. However, estimates of actual returns and allowances in any future period are inherently uncertain and actual returns and allowances may differ from these estimates. If actual or expected future returns and allowances were significantly greater or less than established reserves, a reduction or increase to net revenues would be recorded in the period this determination was made.
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold includes the actual product costs, including inbound freight charges and certain outbound freight charges, purchasing, sourcing, inspection and receiving costs. Warehousing costs are included in selling, general and administrative expenses.
Shipping and Handling Costs	Shipping and Handling Costs Shipping and handling costs that are charged to and reimbursed by a customer are recognized as revenue, while the related expenses incurred by the Company are recorded as cost of goods sold.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred, except for certain materials that are expensed the first time that the advertising takes place. Advertising expenses were $121.5 million, $137.2 million and $126.6 million for fiscal years 2016, 2015 and 2014, respectively. Prepaid advertising totaled $4.0 million and $6.9 million as of December 31, 2016 and January 2, 2016, respectively.
Cash Equivalents	Cash Equivalents Cash equivalents include highly liquid investments with an original maturity of three months or less. Cash equivalents are stated at cost, which approximates market.
Allowance for Uncollectible Accounts	Allowance for Uncollectible Accounts The Company maintains an allowance for uncollectible accounts receivable for estimated losses resulting from its customers’ failure to make required payments. Company management evaluates the allowance for uncollectible accounts receivable based on a review of current customer status and historical collection experience.
Inventories	Inventories The Company values its inventory at the lower of cost or market. Cost is determined by the LIFO method for all domestic raw materials and work-in-process inventories and certain domestic finished goods inventories. Cost is determined using the FIFO method for all raw materials, work-in-process and finished goods inventories in foreign countries; certain domestic finished goods inventories; and for all finished goods inventories of the Company’s consumer-direct business, due to the unique nature of those operations. The Company has applied these inventory cost valuation methods consistently from year to year.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated on the basis of cost and include expenditures for computer hardware and software, store furniture and fixtures, office furniture and machinery and equipment. Normal repairs and maintenance are expensed as incurred. Depreciation of property, plant and equipment is computed using the straight-line method. The depreciable lives range from 14 to 20 years for buildings and improvements, from 5 to 10 years for leasehold improvements and from 3 to 10 years for machinery, equipment and software.
Operating Leases	Operating Leases The Company leases its retail stores and certain distribution and office facilities under operating leases. In addition to the minimum lease payments, leases may include rent escalation clauses, contingent rental expense and lease incentives, including rent holidays and tenant improvement allowances. Rent expense is recognized on a straight-line basis over the term of the lease from the time at which the Company takes possession of the property. Landlord-provided tenant improvement allowances are recorded in other liabilities and amortized as a credit to rent expense over the term of the lease. Leasehold improvements are depreciated at the lesser of the estimated useful life or lease term, including reasonably-assured lease renewals as determined at lease inception.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs represent commitment fees, legal and other third-party costs associated with obtaining commitments for financing that result in a closing of such financings for the Company. These costs are amortized into earnings through interest expense over the terms of the respective agreements. Costs incurred in seeking financing transactions that do not close are expensed in the period in which it is determined that the financing will not close.
Goodwill and Other Intangibles	Goodwill and Other Intangibles Goodwill represents the excess of the purchase price over the fair value of net tangible and identifiable intangible assets of acquired businesses. Indefinite-lived intangibles include trademarks and trade names. Goodwill and intangible assets deemed to have indefinite lives are not amortized, but are subject to impairment tests at least annually. The Company reviews the carrying amounts of goodwill and indefinite-lived intangible assets by reporting unit at least annually, or when indicators of impairment are present, to determine if such assets may be impaired. If the carrying amounts of these assets are not recoverable based upon discounted cash flow and market approach analyses, the carrying amounts of such assets are reduced by the estimated difference between the carrying values and estimated fair values. The Company includes assumptions about expected future operating performance as part of a discounted cash flow analysis to estimate fair value. If the carrying value of these assets is not recoverable, based on the discounted cash flow analysis, management performs the next step, which compares the fair value of the reporting unit to the carrying value of the tangible and intangible net assets of the reporting units. Goodwill is considered impaired if the recorded value of the tangible and intangible net assets exceeds the fair value of the reporting unit. The Company may first assess qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying value. The Company would not be required to quantitatively determine the fair value of the indefinite-lived intangible unless the Company determines, based on the qualitative assessment, that it is more likely than not that its fair value is less than the carrying value. The Company may skip the qualitative assessment and quantitatively test indefinite-lived intangibles by comparison of the individual carrying values to the fair value. Future cash flows of the individual indefinite-lived intangible assets are used to measure their fair value after consideration by management of certain assumptions, such as forecasted growth rates and cost of capital, which are derived from internal projections and operating plans. The Company performs its annual testing for goodwill and indefinite-lived intangible asset impairment at the beginning of the fourth quarter of the fiscal year for all reporting units. See Note 4 to the consolidated financial statements for information related to the results of the Company's annual test.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or an asset group may not be recoverable. Each impairment test is based on a comparison of the carrying amount of the asset or asset group to the future undiscounted net cash flows expected to be generated by the asset or asset group. If such assets are considered to be impaired, the impairment amount to be recognized is the amount by which the carrying value of the assets exceeds their fair value. See Note 16 to the consolidated financial statements for information related to long-lived assets that were determined to be impaired.
Retirement Benefits	Retirement Benefits The determination of the obligation and expense for retirement benefits is dependent on the selection of certain actuarial assumptions used in calculating such amounts. These assumptions include, among others, the discount rate, expected long-term rate of return on plan assets, mortality rates and rates of increase in compensation. These assumptions are reviewed with the Company’s actuaries and updated annually based on relevant external and internal factors and information, including, but not limited to, long-term expected asset returns, rates of termination, regulatory requirements and plan changes. See Note 12 to the consolidated financial statements for additional information. The Company has elected to measure its defined benefit plan assets and obligations as of December 31^st of each year, regardless of the Company's actual fiscal year end date, which is the Saturday nearest to December 31.
Income Taxes	Income Taxes The provision for income taxes is based on the geographic dispersion of the earnings reported in the consolidated financial statements. A deferred income tax asset or liability is determined by applying currently-enacted tax laws and rates to the cumulative temporary differences between the carrying values of assets and liabilities for financial statement and income tax purposes. The Company records an increase in liabilities for income tax accruals associated with tax benefits claimed on tax returns but not recognized for financial statement purposes (unrecognized tax benefits). The Company recognizes interest and penalties related to unrecognized tax benefits through interest expense and income tax expense, respectively.
Foreign Currency	Foreign Currency For most of the Company’s international subsidiaries, the local currency is the functional currency. Assets and liabilities of these subsidiaries are translated into U.S. dollars at the year-end exchange rate. Operating statement amounts are translated at average exchange rates for each period. The cumulative translation adjustments resulting from changes in exchange rates are included in the consolidated balance sheets as a component of accumulated other comprehensive income (loss) in stockholders’ equity. Transaction gains and losses are included in the consolidated statements of operations and were not material for fiscal years 2016, 2015 and 2014.

Earnings Per Share [Abstract]
Earnings Per Share	The Company calculates earnings per share in accordance with FASB ASC Topic 260, Earnings Per Share (“ASC 260”). ASC 260 addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting, and, therefore, need to be included in the earnings allocation in computing earnings per share under the two-class method. Under the guidance in ASC 260, the Company’s unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are participating securities and must be included in the computation of earnings per share pursuant to the two-class method.

Share-based Compensation	Stock-based compensation expense recognized in the consolidated statements of operations for fiscal years 2016, 2015 and 2014 was based on awards ultimately expected to vest and, as such, was reduced for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on historical experience.
