Accounting Changes and Error Corrections [Abstract]

New Accounting Pronouncements, Policy [Policy Text Block]

NEW ACCOUNTING STANDARDS

The Financial Accounting Standards Board (“FASB”) issued the following Accounting Standards Updates (“ASU”) that the Company adopted during fiscal year 2020 . The following is a summary of the effect of adoption of this new standard.



Standard	Description	Effect on the Financial Statements or Other Significant Matters
ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): 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 determine credit loss estimates.	The Company adopted ASU 2016-13 at the beginning of the first quarter on a prospective basis. The Company adjusted its business policies and processes relating to the measurement of allowances for credit losses to consider reasonable and supportable information to determine expected credit losses on accounts receivable. The adoptions of the ASU did not have a material effect on the consolidated financial statements.
ASU 2017-04, Intangibles Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment	Eliminates step two of the goodwill impairment test under legacy US GAAP. Annual and interim goodwill impairment tests are performed by comparing the fair value of a reporting unit with its carrying amount and the amount by which the carrying amount exceeds the reporting unit’s fair value will be recognized as an impairment charge.	The Company adopted the ASU at the beginning of the first quarter on a prospective basis. The adoption of this guidance did not have a significant impact on the Company’s financial statements and all prospective impairment tests will be completed under this standard.

Earnings Per Share

Earnings Per Share [Abstract]

Earnings Per Share

EARNINGS PER SHARE

The Company calculates earnings per share in accordance with FASB Accounting Standards Codification (“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.



	Quarter Ended
(In millions, except per share data)	March 28, 2020			March 30, 2019
Numerator:
Net earnings attributable to Wolverine World Wide, Inc.	$	13.0		$	40.5
Adjustment for earnings allocated to non-vested restricted common stock	(0.2		)	(0.8		)
Net earnings used in calculating basic and diluted earnings per share	$	12.8		$	39.7
Denominator:
Weighted average shares outstanding	81.4			91.0
Adjustment for non-vested restricted common stock	(0.3)			(1.0)
Shares used in calculating basic earnings per share	81.1			90.0
Effect of dilutive stock options	0.9			1.8
Shares used in calculating diluted earnings per share	82.0			91.8
Net earnings per share:
Basic	$	0.16		$	0.44
Diluted	0.16			0.43

For the quarters ended March 28, 2020 and March 30, 2019 , 167,298 and 33,614 outstanding stock options, respectively, have not been included in the denominator for the computation of diluted earnings per share because they were anti-dilutive.

GOODWILL AND INDEFINITE-LIVED INTANGIBLES

The changes in the carrying amount of goodwill are as follows:



	Quarter Ended
(In millions)	March 28, 2020			March 30, 2019
Goodwill balance at beginning of the year	$	438.9		$	424.4
Foreign currency translation effects	(4.2		)	1.5
Goodwill balance at end of the quarter	$	434.7		$	425.9

The Company’s indefinite-lived intangible assets, which comprise trade names and trademarks, totaled $ 604.5 million as of March 28, 2020 , December 28, 2019 and March 30, 2019 . The carrying value of the Company’s Sperry ^® trade name was $ 518.2 million as of March 28, 2020 . Based on the interim impairment assessment as of March 28, 2020, it was determined there were no triggering events of impairment for goodwill and indefinite-lived intangible assets. If the operating results for Sperry ^® were to decline in future periods compared to current projections, or if further deterioration of macroeconomic conditions due to the COVID-19 pandemic adversely affect the value of the Company’s Sperry ^® trade name and goodwill balances, the Company may need to record a non-cash impairment charge. We continue to monitor the significant global economic uncertainty as a result of COVID-19 to assess the outlook for demand for our products and the impact on our business and financial performance.

Accounts Receivables [Abstract]

Loans, Notes, Trade and Other Receivables Disclosure [Text Block]

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 2020. Under the agreement, up to $ 150.0 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 condensed 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 as of the end of the first quarter of 2020 . For receivables sold under the agreement, 90 % of the stated amount is paid 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.



	Quarter Ended
(In millions)	March 28, 2020		March 30, 2019
Accounts receivable sold	$	14.1	$	—
Fees charged	0.1		—

The fees charged are recorded in other expense. Net proceeds of this program are classified in operating activities in the consolidated condensed statements of cash flows. The amount outstanding under this program was $3.2 million and $0 as of March 28, 2020 and March 30, 2019 , respectively.

- Definition

The entire disclosure for claims held for amounts due a entity, excluding financing receivables. Examples include, but are not limited to, trade accounts receivables, notes receivables, loans receivables. Includes disclosure for allowance for credit losses.

Revenue From Contracts With Customers [Abstract]

Revenue from Contract with Customer [Text Block]

REVENUE FROM CONTRACTS WITH CUSTOMERS

Revenue Recognition and Performance Obligations

The Company recognizes revenue in accordance with FASB ASC Topic 606, Revenue from Contracts with Customers . Revenue is recognized upon the transfer of promised goods or services to customers, in an amount that reflects the expected consideration to be received in exchange for those goods or services. The Company identifies the performance obligation in the contract, determines the transaction price, allocates the transaction price to the performance obligations and recognizes revenue upon completion of the performance obligation. Revenue is recognized net of variable consideration and any taxes collected from customers, which are subsequently remitted to governmental authorities.

The Company has agreements to license symbolic intellectual property with minimum guarantees or fixed consideration. The Company is due $ 29.3 million of remaining fixed transaction price under its license agreements as of March 28, 2020 , which it expects to recognize per the terms of its contracts over the course of time through December 2024 . The Company has elected to omit the remaining variable consideration under its license agreements given the Company recognizes revenue equal to what it has the right to invoice and that amount corresponds directly with the value to the customer of the Company’s performance to date.

The Company provides disaggregated revenue by sales channel, including the wholesale and consumer-direct sales channels, reconciled to the Company’s reportable segments. The wholesale channel includes royalty revenues due to the similarity in the Company’s oversight and management, customer base, the performance obligation (footwear and apparel goods) and point in time completion of the performance obligation.

Reserves for Variable Consideration

Revenue is recorded at the net sales price (“transaction price”), which includes estimates of variable consideration for which reserves are established. Components of variable consideration include trade discounts and allowances, product returns, customer markdowns, customer rebates and other sales incentives relating to the sale of the Company’s products. These reserves, as detailed below, are based on the amounts earned, or to be claimed on the related sales. These estimates take into consideration a range of possible outcomes, which are probability-weighted in accordance with the expected value method for relevant factors such as current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the respective underlying contracts. Revenue recognized during the fiscal periods presented related to the Company’s contract liabilities was nominal.

The Company’s contract balances are as follows:



(In millions)	March 28, 2020		December 28, 2019		March 30, 2019
Product returns reserve	$	10.3	$	11.4	$	10.9
Customer markdowns reserve	5.4		4.4		4.8
Other sales incentives reserve	2.3		2.3		2.5
Customer rebates liability	10.2		12.0		11.3
Customer advances liability	3.4		7.2		3.5

The amount of variable consideration included in the transaction price may be constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized under the contract will not occur in a future period. Actual amounts of consideration ultimately received may differ from initial estimates. If actual results in the future vary from initial estimates, the Company subsequently adjusts these estimates, which affects net revenue and earnings in the period such variances become known.

Total debt	$	1,226.1		$	798.4		$	771.3

On December 6, 2018, the Company amended its credit agreement (as amended, the "Credit Agreement"). The Credit Agreement includes a $ 200.0 million term loan facility (“Term Loan A”) and an $ 800.0 million Revolving Credit Facility, both with maturity dates of December 6, 2023. 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. Term Loan A requires quarterly principal payments with a balloon payment due on December 6, 2023. The scheduled principal payments due over the next 12 months total $ 12.5 million as of March 28, 2020 and are recorded as current maturities of long-term debt on the consolidated condensed balance sheets.

The Revolving Credit Facility allows the Company to borrow up to an aggregate amount of $800.0 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 $ 5.7 million , $ 5.7 million and $ 2.3 million as of March 28, 2020 , December 28, 2019 and March 30, 2019 , 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 0.125% to 0.750% , or (2) the Eurocurrency Rate plus an Applicable Margin as determined by the Company’s Consolidated Leverage Ratio, within a range of 1.125% to 1.750% (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 March 28, 2020 , Term Loan A and the Revolving Credit Facility had weighted-average interest rates of 2.79 % and 2.39% , respectively.

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 and a minimum Consolidated Interest Coverage Ratio (all capitalized terms used in this paragraph are as defined in the Credit Agreement). As of March 28, 2020 , the Company was in compliance with all covenants and performance ratios under the Credit Agreement.

The Company has $ 250.0 million of senior notes outstanding that are due on September 1, 2026 (the “Senior Notes”). The Senior Notes bear interest at 5.00% with the related interest payments due semi-annually. The Senior Notes are guaranteed by substantially all of the Company’s domestic subsidiaries.

The Company has a foreign revolving credit facility with aggregate available borrowings of $ 4.0 million that are uncommitted and, therefore, each borrowing against the facility is subject to approval by the lender. There were no borrowings against this facility as of March 28, 2020 , December 28, 2019 and March 30, 2019 .

The Company included in interest expense the amortization of deferred financing costs of $ 0.4 million and $ 0.4 million for the quarters ended March 28, 2020 and March 30, 2019 , respectively.

Leases [Abstract]

Lessee, Operating Leases [Text Block]

LEASES

The Company’s leases consist primarily of corporate offices, retail stores, distribution centers, showrooms, vehicles and office equipment. The Company leases assets in the normal course of business to meet its current and future needs while providing flexibility to its operations. The Company enters into contracts with third parties to lease specifically identified assets. Most of the Company’s leases have contractually specified renewal periods. Most retail store leases have early termination clauses that the Company can elect if stipulated sales amounts are not achieved. The Company determines the lease term for each lease based on the terms of each contract and factors in renewal and early termination options if such options are reasonably certain to be exercised.

The following is a summary of the Company’s lease cost.

Financial Instruments and Risk Management

Financial Instruments and Risk Management

DERIVATIVE FINANCIAL INSTRUMENTS

The Company follows FASB ASC Topic 815, Derivatives and Hedging ("ASC 815"), which requires that all derivative instruments be recorded on the consolidated condensed balance sheets at fair value by establishing criteria for designation and effectiveness of hedging relationships. The Company does not hold or issue financial instruments for trading purposes.

The Company utilizes foreign currency forward exchange contracts designated as cash flow hedges 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 extended out to a maximum of 503 days, 545 days and 531 days, as of March 28, 2020 , December 28, 2019 and March 30, 2019 , respectively. If, in the future, the foreign exchange contracts are determined not to be highly effective or are terminated before their contractual termination dates, the Company would remove the hedge designation from those contracts and reclassify into earnings the unrealized gains or losses that would otherwise be included in accumulated other comprehensive income (loss) (“AOCI”) within stockholders’ equity. The Company did not have any reclassifications during the quarters ended March 28, 2020 and March 30, 2019 .

The Company also utilizes foreign currency forward exchange contracts that are not designated as hedging instruments to manage foreign currency transaction exposure. Foreign currency derivatives not designated as hedging instruments 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 unless otherwise terminated, will mature on July 13, 2020 and December 6, 2023 , respectively. These agreements, which exchange floating rate for fixed rate interest payments over the life of the agreements without the exchange of the underlying notional amounts, have been designated as cash flow hedges of the underlying 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 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 borrowing, as well as its risk management objective and strategy for undertaking the hedge transactions. This process included linking the derivative to the specific liability or asset on the balance sheet. The Company also assessed at the inception of each hedge, and continues to assess on an ongoing basis, whether the derivatives used in the hedging transactions are highly effective in offsetting changes in the cash flows of the hedged item.

The Company has a cross currency swap to minimize the impact of exchange rate fluctuations. The hedging instrument, which, unless otherwise terminated, will mature on September 1, 2021 , has been designated as a hedge of a net investment in a foreign operation. The Company will pay 2.75 % on the euro-denominated notional amount and receive 5.00 % on the U.S. dollar notional amount, with an exchange of principal at maturity. Changes in fair value related to movements in the foreign currency exchange spot rate are recorded in AOCI, offsetting the currency translation adjustment related to the underlying net investment that is also recorded in AOCI. All other changes in fair value are recorded in interest expense. In accordance with ASC 815, the Company has formally documented the relationship between the cross-currency swap and the Company’s investment in its euro-denominated subsidiary, as well as its risk management objective and strategy for undertaking the hedge transaction. This process included linking the derivative to its net investment on the balance sheet. The Company also assessed at the hedge’s inception, and continues to assess on an ongoing basis, whether the derivative used in the hedging transaction is highly effective in offsetting changes in expected cash flows of the hedged item.

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

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company maintains management and operational activities in overseas subsidiaries, and its foreign earnings are taxed at rates that are different than the U.S. federal statutory income tax rate. A significant amount of the Company’s earnings are generated by its Canadian, European and Asian subsidiaries and, to a lesser extent, in jurisdictions that are not subject to income tax. The Company intends to permanently reinvest all non-cash undistributed earnings outside of the U.S. and has, therefore not established a deferred tax liability on that amount of foreign unremitted earnings. However, if these non-cash undistributed earnings were repatriated, the Company would be required to accrue and pay applicable U.S. taxes and withholding taxes payable to various countries. It is not practicable to estimate the amount of the deferred tax liability associated with these non-cash unremitted earnings due to the complexity of the hypothetical calculation. The Company’s effective tax rates for the quarters ended March 28, 2020 and March 30, 2019 were (32.3)% and 13.2% , respectively. The decrease in the current year effective tax rate is driven by favorable discrete benefits related to stock compensation and a favorable settlement of an audit in a foreign jurisdiction. The effect of the discrete items on the current year effective tax rate was increased due to the reduction in pretax book income in the first quarter of 2020 compared to the first quarter of 2019. The Company is subject to periodic audits by U.S. federal, state, local and non-U.S. tax authorities. Currently, the Company is undergoing routine periodic audits in both U.S. federal, state, local and non-U.S. 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 condensed financial statements. 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 2015 in the majority of tax jurisdictions.

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

FAIR VALUE MEASUREMENTS

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.

Recurring Fair Value Measurements

The following table sets forth financial assets and liabilities measured at fair value in the consolidated condensed 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)
(In millions)	March 28, 2020			December 28, 2019			March 30, 2019
Financial assets:
Derivatives	$	6.6		$	2.3		$	7.9
Financial liabilities:
Derivatives	$	(11.6	)	$	(6.6	)	$	(6.1	)

The fair value of foreign currency forward exchange contracts represents the estimated receipts or payments necessary to terminate the contracts. The two interest rate swaps are valued based on the current forward rates of the future cash flows. The fair value of the cross-currency swap is determined using the current forward rates and changes in the spot rate.

Fair Value Disclosures

The Company’s financial instruments that are not recorded at fair value consist of cash and cash equivalents, accounts and notes receivable, accounts payable, borrowings under revolving credit agreements and other short-term and long-term debt. The carrying amount of these financial instruments is historical cost, which approximates fair value, except for the debt. The carrying value and the fair value of the Company’s debt, excluding capital leases, are as follows:



(In millions)	March 28, 2020		December 28, 2019		March 30, 2019
Carrying value	$	1,226.1	$	798.4	$	771.3
Fair value	1,228.0		817.6		782.2

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).

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

LITIGATION AND CONTINGENCIES

Litigation

The Company operated a leather tannery in Rockford, Michigan from the early 1900s through 2009 (the “Tannery”). The Company also owns a parcel on House Street in Plainfield Township that the Company used for the disposal of Tannery byproducts until about 1970 (the "House Street" site). Beginning in the late 1950s, the Company used 3M Company’s Scotchgard™ in its processing of certain leathers at the Tannery. Until 2002 when 3M Company changed its Scotchgard™ formula, Tannery byproducts disposed of by the Company at the House Street site and other locations may have contained PFOA and/or PFOS, two chemicals in the family of compounds known as per- and polyfluoroalkyl substances (together, “PFAS”). PFOA and PFOS help provide non-stick, stain-resistant, and water-resistant qualities, and were used for many decades in commercial products like firefighting foams and metal plating, and in common consumer items like food wrappers, microwave popcorn bags, pizza boxes, Teflon™, carpets and Scotchgard™.

The United States Centers for Disease Control and Prevention has concluded that studies of the health effects of PFOA and PFOS are “inconsistent and inconclusive,” but in May 2016, the Environmental Protection Agency (“EPA”) announced a lifetime health advisory level of 70 parts per trillion ("ppt") combined for PFOA and PFOS. Lifetime health advisories, while not enforceable, serve as guidance and are benchmarks for determining if concentrations of chemicals in tap water from public utilities are safe for public consumption. In January 2018, the Michigan Department of Environmental Quality (“MDEQ”) enacted a drinking water criterion of 70 ppt combined for PFOA and PFOS, which set an official state standard for acceptable concentrations of these contaminants in groundwater used for drinking water purposes. On April 22, 2019, the MDEQ was reorganized into the Michigan Department of Environment, Great Lakes, and Energy (“EGLE”).

The Company has been served with two regulatory actions including a civil action filed by the EGLE under the federal Resource Conservation and Recovery Act of 1976 (“RCRA”), Part 201 of the Michigan Natural Resources and Environmental Protection Act (“NREPA”) and Part 31 of NREPA, and a Unilateral Administrative Order issued by the EPA under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) Section 106. The Company has also been served with individual lawsuits and three putative class action lawsuits. The three putative class action lawsuits were subsequently refiled as a single consolidated putative class action lawsuit.

Civil and Regulatory Actions of EGLE and EPA

On January 10, 2018, EGLE filed a civil action against the Company in the U.S District Court for the Western District of Michigan under RCRA and Parts 201 and 31 of NREPA alleging that the Company’s past and present handling, storage, treatment, transportation and/or disposal of solid waste at the Company’s properties has contributed to the disposal of solid wastes that was done in a way that resulted in releases of PFAS at levels that resulted in detections exceeding applicable Michigan cleanup criteria for PFOA and PFOS (the "EGLE Action"). Plainfield and Algoma Townships intervened in the EGLE Action alleging claims under RCRA, CERCLA, Part 201 of NREPA, and common law nuisance.

On December 19, 2018, the Company filed a third-party complaint against 3M Company seeking, among other things, recovery of the Company’s remediation and other costs incurred in defense of the EGLE Action ("the 3M Action"). On June 20, 2019, the 3M Company filed a counterclaim against the Company in response to the 3M Action, seeking, among other things, contractual and common law indemnity and contribution under CERCLA and Part 201 of NREPA. On February 3, 2020, the parties entered into a consent decree resolving the EGLE Action, which was approved by U.S. District Judge Janet T. Neff on February 19, 2020 (the “Consent Decree”). On February 20, 2020, the Company and the 3M Company entered into a settlement agreement resolving the 3M Action, under which 3M Company paid the Company a lump sum amount of $ 55.0 million during the first quarter of 2020.

Under the Consent Decree, the Company will pay to extend Plainfield Township’s municipal water system to more than 1,000 properties in Plainfield and Algoma Townships, subject to an aggregate cap of $69.5 million. The Consent Decree also obligates the Company to continue maintaining water filters for certain homeowners, resample certain residential wells for PFAS, continue remediation at the Company’s Tannery property and House Street site, and conduct further investigations and monitoring to the assess the presence of PFAS in area groundwater.

On January 10, 2018, the EPA entered a Unilateral Administrative Order (the “Order”) under Section 106(a) of CERCLA, 42 U.S.C. § 9606(a). The effective date of the Order was February 1, 2018. The Order pertained to the Company's Tannery and House Street sites and directed the Company to conduct specified removal actions, including certain time critical removal actions subsequently identified in an April 29, 2019 letter from the EPA, to abate the actual or threatened release of hazardous substances at or from the sites. On October 28, 2019, the EPA and the Company entered into an Administrative Settlement and Order on Consent (“AOC”) that supersedes the Order and addresses the agreed-upon removal actions outlined in the Order. The Company has already completed some of these activities and submitted work plans for completion of the remaining items.

The Company discusses its reserve for remediation costs in the environmental liabilities section below.

Individual and Class Action Litigation

Individual lawsuits and three putative class action lawsuits have been filed against the Company that raise a variety of claims, including claims related to property, remediation, and human health effects. The three putative class action lawsuits were subsequently refiled in the U.S. District Court for the Western District of Michigan as a single consolidated putative class action lawsuit. 3M Company, which sold Scotchgard containing PFAS to the Company, has been named as a co-defendant in the individual lawsuits and consolidated putative class action lawsuit. In addition, the current owner of a former landfill and gravel mining operation sued the Company seeking damages and cost recovery for property damage allegedly caused by the Company’s disposal of tannery waste containing PFAS (this suit collectively with the individual lawsuits and putative class action, the “Litigation Matters”).

Assessing potential liability with respect to the Litigation Matters at this time is difficult. The Litigation Matters are in various stages of discovery and related motions. In addition, there is minimal direct and relevant precedent for these types of claims related to PFAS, and the science regarding the human health effects of PFAS exposure in the environment remains inconclusive and inconsistent, thereby creating additional uncertainties. Due to these factors, combined with the complexities and uncertainties of litigation, the Company is unable to conclude that adverse verdicts resulting from the Litigation Matters are probable, and therefore no amounts are currently reserved for these claims. The Company intends to continue to vigorously defend itself against these claims.

In addition, in December 2018 the Company filed a lawsuit against certain of its historic liability insurers, seeking their participation in the Company's defense and remediation efforts. No estimated recoveries from legacy insurance policies have been recognized.

Other Litigation

The Company is also involved in 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 are not expected to have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

Environmental Liabilities

The following is a summary of the activity with respect to the environmental remediation reserve established by the Company:



	Quarter Ended
(In millions)	March 28, 2020			March 30, 2019
Remediation liability at beginning of the year	$	124.4		$	22.6
Changes in estimate	—			—
Amounts paid	(8.0		)	(2.3		)
Remediation liability at the end of the quarter	$	116.4		$	20.3

The reserve balance as of March 28, 2020 includes $ 39.0 million that is expected to be paid within the next twelve months and is recorded as a current obligation in other accrued liabilities, with the remaining $ 77.4 million expected to be paid over the course of up to 25 years, recorded in other liabilities.

The Company's remediation activity at the Tannery property, House Street site and other relevant disposal sites is ongoing. Although the recent Consent Decree has made near-term costs more clear, it is difficult to estimate the long-term cost of environmental compliance and remediation given the uncertainties regarding the interpretation and enforcement of applicable environmental laws and regulations, the extent of environmental contamination and the existence of alternative cleanup methods. Future developments may occur that could materially change the Company’s current cost estimates, including, but not limited to: (i) changes in the information available regarding the environmental impact of the Company’s operations and products; (ii) changes in environmental regulations, changes in permissible levels of specific compounds in drinking water sources, or changes in enforcement theories and policies, including efforts to recover natural resource damages; (iii) new and evolving analytical and remediation techniques; (iv) changes to the form of remediation; (v) success in allocating liability to other potentially responsible parties; and (vi) the financial viability of other potentially responsible parties and third-party indemnitors. For locations at which remediation activity is largely ongoing, the Company cannot estimate a possible loss or range of loss in excess of the associated established reserves for the reasons described above. The Company adjusts recorded liabilities as further information develops or circumstances change.

Minimum Royalties and Advertising Commitments

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 periods subsequent to March 28, 2020 are as follows:



(In millions)	2020		2021		2022		2023		2024		Thereafter
Minimum royalties	$	0.9	$	1.7	$	1.8	$	—	$	—	$	—
Minimum advertising	2.6		3.3		3.4		3.5		3.6		—

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 $ 0.4 million and $ 0.5 million for the quarters ended March 28, 2020 and March 30, 2019 , respectively.

The terms of certain license agreements also require the Company to make advertising expenditures based on the level of sales of the licensed products. In accordance with these agreements, the Company incurred advertising expense of $ 0.6 million and $ 0.4 million for the quarters ended March 28, 2020 and March 30, 2019 , respectively.

BUSINESS ACQUISITIONS

On April 30, 2019, the Company acquired assets and assumed liabilities from Sportlab S.R.L. (“Sportlab”), the distributor of Saucony ^® footwear in Italy. Total purchase consideration of $ 25.2 million includes cash paid, extinguishment of Sportlab’s accounts payable balance that was due to the Company at the time of acquisition and contingent consideration. The contingent consideration was based on sales activity from the date of the acquisition through the end of fiscal 2019 and was paid in the first quarter of fiscal 2020. The detailed amounts of each component of the purchase consideration are as follows:



(In millions)	Purchase Consideration
Cash paid	$	15.1
Extinguishment of Sportlab’s accounts payable balance	4.6
Contingent consideration	5.5
Total purchase consideration	$	25.2

The Company accounted for the acquisition under the provisions of FASB ASC Topic 805, Business Combinations . The related assets acquired and liabilities assumed were recorded at fair value on the acquisition date. The operating results for the acquired Saucony ^® distribution business are included in the Company’s consolidated results of operations beginning April 30, 2019, and are included in the Wolverine Boston Group reporting group for segment reporting purposes.

The final allocation of the purchase price as of December 28, 2019 was:



(In millions)	Initial Valuation
Accounts receivable	$	1.8
Inventories	6.2
Goodwill	12.0
Amortizable intangibles	12.9
Total assets acquired	32.9
Deferred income taxes	3.2
Other liabilities	4.5
Total liabilities assumed	7.7
Net assets acquired	$	25.2

The excess of the purchase price over the fair value of the net assets acquired, amounting to $12.0 million , was recorded as goodwill in the consolidated balance sheet and was assigned to the Wolverine Boston Group reportable segment. The goodwill that was recognized is attributable to the efficiencies to be gained by integrating operations with the Saucony ^® distribution business purchased from Sportlab. Other intangible assets acquired include order backlog, valued at $ 1.7 million , and customer relationship assets, valued at $ 11.2 million , which had estimated useful lives at the acquisition date of 7 months and 14 years , respectively.

Earnings Per Share [Abstract]
Earnings Per Share	The Company calculates earnings per share in accordance with FASB Accounting Standards Codification (“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.

- Definition
