Notes to Condensed Consolidated Financial Statements

(Dollars in millions, except share data)

(unaudited)

1. Basis of Presentation

The Condensed Consolidated Financial Statements have been prepared by Herman Miller, Inc. (“the Company”) in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Management believes the disclosures made in this document are adequate with respect to interim reporting requirements. Unless otherwise noted or indicated by the context, all references to "Herman Miller," "we," "our," "Company" and similar references are to Herman Miller, Inc., its predecessors, and controlled subsidiaries. 

The accompanying unaudited Condensed Consolidated Financial Statements, taken as a whole, contain all adjustments that are of a normal recurring nature necessary to present fairly the financial position of the Company as of November 28, 2020. Operating results for the three and six months ended November 28, 2020 are not necessarily indicative of the results that may be expected for the year ending May 29, 2021. It is suggested that these Condensed Consolidated Financial Statements be read in conjunction with the financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended May 30, 2020. All intercompany transactions have been eliminated in the Condensed Consolidated Financial Statements. The financial statements of equity method investments are not consolidated. Certain prior year amounts in the Condensed Consolidated Financial Statements have been reclassified to conform with current year presentation.

2. Recently Issued Accounting Standards

Recently Adopted Accounting Standards

On May 31, 2020, the Company adopted Accounting Standards Update ("ASU") No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" using the modified retrospective method. This update replaces the existing incurred loss impairment model with an expected loss model and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates including customer credit quality, historical write-off trends and general information regarding industry trends and the macroeconomic environment. The adoption did not have a material impact on the Company's financial statements, accounting policies or methods utilized to determine the allowance for doubtful accounts.

On May 31, 2020, the Company adopted ASU No. 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement" using the prospective method. This update modifies certain disclosure requirements for fair value measurements. The adoption did not have a material impact on the Company's financial statements.

Recently Issued Accounting Standards Not Yet Adopted

The Company is currently evaluating the impact of adopting the following relevant standards issued by the FASB:

Standard		Description	Effective Date
2018-14	Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans	This update eliminates, adds and clarifies certain disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans. Early adoption is permitted. The Company does not expect the adoption of this standard to have a material impact on its financial statements.	May 30, 2021

All other issued and not yet effective accounting standards are not relevant to the Company.

This compares to purchases of $23.8 million and $45.7 million for the three and six months ended November 30, 2019, respectively.

10 Form 10-Q

During the fourth quarter of fiscal 2020, the Company determined it was more likely than not that the fair value of certain right-of-use assets were below their carrying values and assessed these assets for impairment. As result of this assessment the Company recorded an impairment of $19.3 million in the Consolidated Statements of Comprehensive Income in the fourth quarter of fiscal 2020 which is the primary driver of lower operating lease cost in the three and six months ended November 28, 2020 compared to the prior year.

At November 28, 2020, the Company had no financing leases. The undiscounted annual future minimum lease payments related to the Company's right-of-use assets are summarized by fiscal year in the following table:

(In millions)
2021	$	25.7
2022	49.4
2023	46.5

5. Acquisitions

Nine United Denmark A/S

On June 7, 2018, the Company acquired 33% of the outstanding equity of Nine United Denmark A/S, d/b/a HAY and subsequently renamed to HAY ApS ("HAY”), a Copenhagen, Denmark-based, design leader in furniture and ancillary furnishings for residential and contract markets in Europe and Asia. The Company acquired its 33% ownership interest in HAY for approximately $65.5 million in cash. The Company also acquired the rights to the HAY brand in North America under a long-term license agreement for approximately $4.8 million in cash.

On December 2, 2019, the Company obtained a controlling financial interest in HAY through the purchase of an additional 34% ownership interest. This acquisition allows the Company to further promote growth and development of HAY's ancillary product lines and continue to support product innovation and sales growth. The Company previously accounted for its ownership interest in HAY as an equity method investment, but upon increasing its ownership to 67%, the Company consolidated the operations of HAY. Total consideration paid for an additional 34% ownership interest of HAY was $79.0 million, exclusive of HAY cash on hand. The Company funded the acquisition with cash and cash equivalents.

The previously mentioned HAY long-term licensing agreement was deemed to be a contractual preexisting relationship. As a result of the business combination, the Company recorded this arrangement at its December 2, 2019 fair value,

Herman Miller, Inc. and Subsidiaries 11

which resulted in an increase in goodwill of $10.0 million and a net gain of approximately $6 million, which was recorded within “Gain on consolidation of equity method investments" within the Condensed Consolidated Statements of Comprehensive Income during the three months ended May 30, 2020. The goodwill was recorded within the Company’s Retail segment.

The Company is a party to options, that if exercised, would require it to purchase the remaining 33% of the equity in HAY, at fair market value. This remaining redeemable noncontrolling interest in HAY is classified outside of permanent equity in the Consolidated Balance Sheets and is carried at the current estimated redemption amount.

The allocation of the purchase price was finalized during the first quarter of fiscal 2021. The following table presents the allocation of purchase price related to acquired tangible assets:

(In millions)
Cash	$	12.1
Working capital, net of cash and inventory step-up	12.3
Net property and equipment	0.9
Other assets	3.9
Other liabilities	(3.1)
Net assets acquired	$	26.1

The purchase of the additional equity interest in HAY was considered to be an acquisition achieved in stages, whereby the previously held equity interest was remeasured as of the acquisition date. The Company considered multiple factors in determining the fair value of the previously held equity method investment, including the price negotiated with the selling shareholder for the 34% equity interest in HAY, an income valuation model (discounted cash flow) and current trading multiples for comparable companies. Based on this analysis, the Company recognized an immaterial non-taxable gain on the remeasurement of the previously held equity method investment of $67.8 million in the third quarter of fiscal 2020. The net gain has been recognized in “Gain on consolidation of equity method investments" within the Condensed Consolidated Statements of Comprehensive Income during the three months ended May 30, 2020.

The following table summarizes the acquired identified intangible assets, valuation method employed, useful lives and fair value, as determined by the Company at the acquisition date:

(In millions)	Valuation Method	Useful Life (years)	Fair Value
Inventory Step-up	Comparative Sales Approach	0.8	$	3.4
Backlog	Multi-Period Excess Earnings	0.3	1.7
Deferred Revenue	Adjusted Fulfillment Cost Method	0.1	(2.2)
Tradename	Relief from Royalty	Indefinite	60.0
Product Development	Relief from Royalty	8.0	22.0
Customer Relationships	Multi-Period Excess Earnings	9.0	34.0
Total			$	118.9

Goodwill related to the acquisition was recorded within the International Contract segment for $101.1 million and the Retail segment for $10.0 million. Subsequent to the acquisition, the goodwill recorded to the Retail segment was fully impaired in the fourth quarter of fiscal 2020 based on the results of the Company's annual goodwill impairment assessment.

naughtone

On October 25, 2019 (“Acquisition Date”), the Company purchased the remaining 47.5% equity voting interest in naughtone (Holdings) Limited and naughtone Manufacturing Ltd. (together “naughtone”). naughtone is an upscale, contemporary furniture manufacturer based in Harrogate, North Yorkshire, UK. The completion of the acquisition allows the Company to further promote growth and development of naughtone's ancillary product lines, and continue to support product innovation and sales growth. The Company previously accounted for its ownership interest in naughtone as an equity method investment. Upon increasing its ownership to 100% on the Acquisition Date, the

12 Form 10-Q

Company obtained a controlling financial interest and consolidated the operations of naughtone. Total consideration paid for naughtone on the Acquisition Date was $45.9 million, exclusive of naughtone cash on hand. The Company funded the acquisition with cash and cash equivalents. The allocation of the purchase price was finalized during the fourth quarter of fiscal 2020.

The following table presents the allocation of purchase price related to acquired tangible assets:

(In millions)
Cash	$	5.1
Working capital, net of cash and inventory step-up	1.3
Net property and equipment	0.8
Net assets acquired	$	7.2

The purchase of the remaining equity interest in naughtone was considered to be an acquisition achieved in stages, whereby the previously held equity interest was remeasured as of the Acquisition Date. The Company considered multiple factors in determining the fair value of the previously held equity method investment, including the price negotiated with the selling shareholder for the 47.5% equity interest in naughtone, an income valuation model (discounted cash flow) and current trading multiples for comparable companies. Based on this analysis, the Company recognized a non-taxable gain of approximately $30 million on the remeasurement of the previously held equity method investment of $20.5 million. The net gain has been recognized in “Gain on consolidation of equity method investments" within the Condensed Consolidated Statements of Comprehensive Income during the three and six months ended November 30, 2019.

The following table summarizes the acquired identified intangible assets, valuation method employed, useful lives and fair value, as determined by the Company at the acquisition date:

(In millions)	Valuation Method	Useful Life (years)	Fair Value

Backlog	Multi-Period Excess Earnings	0.3	0.8
Tradename	Relief from Royalty	Indefinite	8.5
Customer Relationships	Multi-Period Excess Earnings	9.0	29.4
Total			$	38.9

Goodwill related to the acquisition was recorded within the North America Contract and International Contract segments for $35.0 million and $22.5 million, respectively.

Pro Forma Results of Operations

The results of naughtone and HAY’s operations have been included in the Consolidated Financial Statements beginning on October 25, 2019 and December 2, 2019 respectively. The following table provides pro forma results of operations for the three and six months ended November 30, 2019, as if naughtone and HAY had been acquired as of June 2, 2019. The pro forma results include certain purchase accounting adjustments such as the estimated change in depreciation and amortization expense on the acquired tangible and intangible assets. Pro forma results do not include any anticipated cost savings from the planned integration of these acquisitions. Accordingly, such amounts are not necessarily indicative of the results that would have occurred if the acquisitions had occurred on the dates indicated or that may result in the future.

Inventories of all other operations are valued using the first-in, first-out (FIFO) method.

7. Goodwill and Indefinite-Lived Intangibles

Goodwill and other indefinite-lived intangible assets included in the Condensed Consolidated Balance Sheets consisted of the following as of November 28, 2020 and May 30, 2020:

(In millions)	Goodwill		Indefinite-lived Intangible Assets
May 30, 2020	$	346.0	$	92.8
Foreign currency translation adjustments	12.5		3.6
November 28, 2020	$	358.5	$	96.4

Goodwill is tested for impairment at the reporting unit level annually, or more frequently, when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. When testing goodwill for impairment, the Company may first assess qualitative factors. If an initial qualitative assessment identifies that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, additional quantitative testing is performed. The Company may also elect to bypass the qualitative testing and proceed directly to the quantitative testing. If the quantitative testing indicates that goodwill is impaired, the carrying value of goodwill is written down to fair value.

Each of the reporting units were reviewed for impairment using a quantitative assessment as of March 31, 2020, our annual testing date. In performing the quantitative impairment test, the Company determined that the fair value of the North America and International reporting units exceeded the carrying amount and, as such, these reporting units were not impaired. The assessment of the Retail and Maharam reporting units indicated that the carrying value of these reporting units exceeded their fair values, and goodwill impairment charges of $88.8 million and $36.7 million, respectively, were recorded in the fourth quarter of fiscal 2020 resulting in no goodwill remaining in either the Retail or Maharam reporting units. Accumulated goodwill impairment losses were $125.3 million as of November 28, 2020 and May 30, 2020.

The fair value of the Company's International reporting unit, which includes $163.7 million of goodwill as of May 30, 2020, exceeded its carrying value by 17%. Due to the level that the reporting unit fair value exceeded the carrying amount and the results of the sensitivity analysis, the Company may need to record an impairment charge if the operating results of its International reporting unit were to decline in future periods.

Intangible assets with indefinite useful lives are not subject to amortization and are evaluated annually for impairment, or more frequently, when events or changes in circumstances indicate that the fair value of an intangible asset may not be recoverable.

In fiscal 2020, the Company performed quantitative assessments in testing indefinite-lived intangible assets for impairment, which resulted in the carrying values of the DWR, Maharam, HAY and naughtone trade names exceeding their fair values by $53.3 million, and impairment charges of this amount were recognized during the fourth quarter of fiscal 2020. If the residual cash flows related to these trade names were to decline in future periods, the Company may need to record an additional impairment charge.

14 Form 10-Q

During the six months ended November 28, 2020, there were no identified indicators of impairment that required the Company to complete an interim quantitative impairment assessment related to any of the Company's reporting units or indefinitely-lived intangible assets.

Related income tax effect	$	0.6	$	0.6	$	0.9	$	1.2

Certain of the Company's equity-based compensation awards contain provisions that allow for continued vesting into retirement. Stock-based awards are considered fully vested for expense attribution purposes when the employee's retention of the award is no longer contingent on providing subsequent service.

Herman Miller, Inc. and Subsidiaries 15

11. Income Taxes

The Company's process for determining the provision for income taxes for the three and six months ended November 28, 2020 involved using an estimated annual effective tax rate which was based on expected annual income and statutory tax rates across the various jurisdictions in which it operates. The effective tax rates were 23.5% and 14.3%, respectively, for the three month periods ended November 28, 2020 and November 30, 2019. The same period in the prior year included a non-taxable gain on consolidation of an equity method investment which is the primary driver of the year over year increase in the effective tax rate. For the three months ended November 28, 2020, the effective tax rate is higher than the United States federal statutory rate due to United States state income taxes and the mix of earnings in tax jurisdictions that had rates that were higher than the United States federal statutory rate. For the three months ended November 30, 2019, the effective tax rate was lower than the United States federal statutory rate mainly as a result from the impact of a non-taxable gain on consolidation of an equity method investment.

The effective tax rates were 22.6% and 16.9%, respectively, for the six month periods ended November 28, 2020 and November 30, 2019. The same period in the prior year included a non-taxable gain on consolidation of an equity method investment which is the primary driver of the year over year increase in the effective tax rate. For the six months ended November 28, 2020, the effective tax rate is higher than the United States federal statutory rate due to United States state income taxes and the mix of earnings in tax jurisdictions that had rates that were higher than the United States federal statutory rate. For the six months ended November 30, 2019, the effective tax rate was lower than the United States federal statutory rate mainly due to the non-taxed nature of the gain on consolidation of an equity method investment.

The Company recognizes interest and penalties related to uncertain tax benefits through income tax expense in its Condensed Consolidated Statements of Comprehensive Income. Interest and penalties recognized in the Company's Condensed Consolidated Statements of Comprehensive Income were negligible for the three and six months ended November 28, 2020 and November 30, 2019.

The Company's recorded liability for potential interest and penalties related to uncertain tax benefits was:

(In millions)	November 28, 2020		May 30, 2020
Liability for interest and penalties	$	1.0	$	0.8
Liability for uncertain tax positions, current	$	2.3	$	1.9

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 twelve months because of the audits. Tax payments related to these audits, if any, are not expected to be material to the Company's Condensed Consolidated Statements of Comprehensive Income.

For the majority of tax jurisdictions, the Company is no longer subject to state, local, or non-United States income tax examinations by tax authorities for fiscal years before 2016.

12. Fair Value Measurements

The Company's financial instruments consist of cash equivalents, marketable securities, accounts and notes receivable, deferred compensation plan, accounts payable, debt, interest rate swaps, foreign currency exchange contracts, redeemable noncontrolling interests, indefinite-lived intangible assets and right-of-use assets. The Company's financial instruments, other than long-term debt, are recorded at fair value.

The carrying value and fair value of the Company's long-term debt, including current maturities, is as follows for the periods indicated:

(In millions)	November 28, 2020		May 30, 2020
Carrying value	$	327.2	$	591.3
Fair value	$	334.4	$	594.0

16 Form 10-Q

The following describes the methods the Company uses to estimate the fair value of financial assets and liabilities recorded in net earnings, which have not significantly changed in the current period:

Cash and cash equivalents — The Company invests excess cash in short term investments in the form of commercial paper and money market funds. Commercial paper is valued at amortized costs while money market funds are valued using net asset value ("NAV").

Mutual Funds-equity — The Company's equity securities primarily include equity mutual funds. The equity mutual fund investments are recorded at fair value using quoted prices for similar securities.

Deferred compensation plan — The Company's deferred compensation plan primarily includes various domestic and international mutual funds that are recorded at fair value using quoted prices for similar securities.

Foreign currency exchange contracts — The Company's foreign currency exchange contracts are valued using an approach based on foreign currency exchange rates obtained from active markets. The estimated fair value of forward currency exchange contracts is based on month-end spot rates as adjusted by market-based current activity. These forward contracts are not designated as hedging instruments.

The following table sets forth financial assets and liabilities measured at fair value through net income and the respective pricing levels to which the fair value measurements are classified within the fair value hierarchy as of November 28, 2020 and May 30, 2020.

(In millions)	November 28, 2020				May 30, 2020
Financial Assets	NAV		Quoted Prices with Other Observable Inputs (Level 2)		NAV		Quoted Prices with Other Observable Inputs (Level 2)

Mutual funds - equity	—		0.7		—		0.7
Foreign currency forward contracts	—		1.4		—		1.1
Deferred compensation plan	—		16.4		—		13.2
Total	$	90.1	$	18.5	$	283.7	$	15.0
Financial Liabilities
Foreign currency forward contracts	$	—	$	0.3	$	—	$	0.8
Total	$	—	$	0.3	$	—	$	0.8

The following describes the methods the Company uses to estimate the fair value of financial assets and liabilities recorded in other comprehensive income, which have not significantly changed in the current period:

Mutual funds-fixed income — The Company's fixed-income securities primarily include fixed income mutual funds and government obligations. These investments are recorded at fair value using quoted prices for similar securities.

Interest rate swap agreements — The value of the Company's interest rate swap agreements is determined using a market approach based on rates obtained from active markets. The interest rate swap agreements are designated as cash flow hedging instruments.

The following is a summary of the carrying and market values of the Company's fixed income mutual funds and equity mutual funds as of the dates indicated:

	November 28, 2020						May 30, 2020
(In millions)	Cost		Unrealized Gain/(Loss)		Market Value		Cost		Unrealized Gain/(Loss)		Market Value
Mutual funds - fixed income	$	6.4	$	0.1	$	6.5	$	6.2	$	0.1	$	6.3
Mutual funds - equity	0.5		0.2		0.7		0.6		0.1		0.7
Total	$	6.9	$	0.3	$	7.2	$	6.8	$	0.2	$	7.0

The cost of securities sold is based on the specific identification method; realized gains and losses resulting from such sales are included in the Condensed Consolidated Statements of Comprehensive Income within "Other (income) expense, net". The Company views its equity and fixed income mutual funds as available for use in its current operations. Accordingly, the investments are recorded within Current Assets within the Condensed Consolidated Balance Sheets.

Derivative Instruments and Hedging Activities

Foreign Currency Forward Contracts

The Company transacts business in various foreign currencies and has established a program that primarily utilizes foreign currency forward contracts to reduce the risks associated with the effects of certain foreign currency exposures. Under this program, the Company's strategy is to have increases or decreases in our foreign currency exposures offset by gains or losses on the foreign currency forward contracts to mitigate the risks and volatility associated with foreign currency transaction gains or losses. Foreign currency exposures typically arise from net liability or asset exposures in non-functional currencies on the balance sheets of our foreign subsidiaries. Foreign currency forward contracts generally settle within 30 days and are not used for trading purposes.

These forward contracts are not designated as hedging instruments. Accordingly, we record the fair value of these contracts as of the end of the reporting period in the Consolidated Balance Sheets with changes in fair value recorded within the Consolidated Statements of Comprehensive Income. The balance sheet classification for the fair values of these forward contracts is to Other current assets for unrealized gains and to Other accrued liabilities for unrealized losses. The Consolidated Statements of Comprehensive Income classification for the fair values of these forward contracts is to Other (income) expense, net, for both realized and unrealized gains and losses.

Interest Rate Swaps

The Company enters into interest rate swap agreements to manage its exposure to interest rate changes and its overall cost of borrowing. The Company's interest rate swap agreements were entered into to exchange variable rate interest payments for fixed rate payments over the life of the agreement without the exchange of the underlying notional amounts. The notional amount of the interest rate swap agreements is used to measure interest to be paid or received. The differential paid or received on the interest rate swap agreements is recognized as an adjustment to interest expense.

18 Form 10-Q

The interest rate swaps were designated cash flow hedges at inception and the facts and circumstances of the hedged relationship remains consistent with the initial quantitative effectiveness assessment in that the hedged instruments remain an effective accounting hedge as of November 28, 2020. Since a designated derivative meets hedge accounting criteria, the fair value of the hedge is recorded in the Consolidated Statements of Stockholders’ Equity as a component of Accumulated other comprehensive loss, net of tax. The ineffective portion of the change in fair value of the derivatives is immediately recognized in earnings. The interest rate swap agreements are assessed for hedge effectiveness on a quarterly basis.

As of November 28, 2020, the Company had the following two outstanding interest rate swap agreements:

(In millions)	Notional Amount		Forward Start Date	Termination Date	Effective Fixed Interest Rate
September 2016 Interest Rate Swap	$	150.0	January 3, 2018	January 3, 2028	1.949	%
June 2017 Interest Rate Swap	$	75.0	January 3, 2018	January 3, 2028	2.387	%

The swaps above effectively converted indebtedness anticipated to be borrowed on the Company's revolving line of credit up to the notional amounts from a LIBOR-based floating interest rate plus applicable margin to an effective fixed interest rate plus applicable margin under the agreements as of the forward start date.

As of November 28, 2020, the fair value of the Company’s two outstanding interest rate swap agreements was a liability of $23.5 million. The liability fair value was recorded within "Other liabilities" within the Condensed Consolidated Balance Sheets.

The following table summarizes the effects of the interest rate swap agreements for the three and six months ended:

	Three Months Ended				Six Months Ended
(In millions)	November 28, 2020		November 30, 2019		November 28, 2020		November 30, 2019
Gain (loss) recognized in Other comprehensive loss (effective portion)	$	0.9	$	3.4	$	1.2	$	(5.3)
(Loss) gain reclassified from Accumulated other comprehensive loss into earnings	$	(1.1)	$	—	$	(2.2)	$	0.1

There were no gains or losses recognized in earnings for hedge ineffectiveness for the three and six month periods ended November 28, 2020 and November 30, 2019, respectively. The amount of loss expected to be reclassified from Accumulated other comprehensive loss into earnings during the next twelve months is $4.4 million, and net of tax is $3.3 million.

Redeemable Noncontrolling Interests

Changes in the Company's redeemable noncontrolling interest in HAY for the six months ended November 28, 2020 are as follows:

(In millions)	November 28, 2020
Beginning Balance	$	50.4
Net income attributable to redeemable noncontrolling interests	2.0
Distributions to redeemable noncontrolling interests	(2.7)
Cumulative translation adjustments attributable to redeemable noncontrolling interests	2.8
Foreign currency translation adjustments	4.0
Ending Balance	$	56.5

During August 2019, the Company acquired all of the remaining redeemable noncontrolling equity interests in the Company's subsidiary, Herman Miller Consumer Holdings, Inc. for $20.4 million.

13. Commitments and Contingencies

Product Warranties

The Company provides coverage to the end-user for parts and labor on products sold under its warranty policy and for other product-related matters. The standard length of warranty is 12 years for the majority of products sold; however, this varies depending on the product classification. The Company does not sell or otherwise issue warranties or warranty extensions as stand-alone products. Reserves have been established for various costs associated with the Company's warranty program. General warranty reserves are based on historical claims experience and other currently available information and are periodically adjusted for business levels and other factors. Specific reserves are established once an issue is identified with the amounts for such reserves based on the estimated cost of correction. The Company provides an assurance-type warranty that ensures that products will function as intended. As such, the Company's estimated warranty obligation is accounted for as a liability and is recorded within current and long-term liabilities within the Condensed Consolidated Balance Sheets.

Changes in the warranty reserve for the stated periods were as follows:

	Three Months Ended				Six Months Ended
(In millions)	November 28, 2020		November 30, 2019		November 28, 2020		November 30, 2019
Accrual Balance — beginning	$	60.3	$	53.3	$	59.2	$	53.1
Accrual for warranty matters	2.7		6.3		7.3		11.6

Accrual Balance — ending	$	59.8	$	54.6	$	59.8	$	54.6

Guarantees

The Company is periodically required to provide performance bonds to do business with certain customers. These arrangements are common in the industry and generally have terms ranging between one year and three years. The bonds are required to provide assurance to customers that the products and services they have purchased will be installed and/or provided properly and without damage to their facilities. The bonds are provided by various bonding agencies. However, the Company is ultimately liable for claims that may occur against them. As of November 28, 2020, the Company had a maximum financial exposure related to performance bonds totaling approximately $5.5 million. The Company has no history of claims, nor is it aware of circumstances that would require it to pay, under any of these arrangements. The Company also believes that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially affect the Company's Consolidated Financial Statements. Accordingly, no liability has been recorded in respect to these bonds as of either November 28, 2020 or May 30, 2020.

The Company has entered into standby letter of credit arrangements for purposes of protecting various insurance companies and lessors against default on insurance premium and lease payments. As of November 28, 2020, the Company had a maximum financial exposure from these standby letters of credit totaling approximately $9.8 million, all of which is considered usage against the Company's revolving line of credit. The Company has no history of claims, nor is it aware of circumstances that would require it to perform under any of these arrangements and believes that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially

20 Form 10-Q

affect the Company's Consolidated Financial Statements. Accordingly, no liability has been recorded in respect to these arrangements as of November 28, 2020 and May 30, 2020.

Contingencies

The Company is also involved in legal proceedings and litigation arising in the ordinary course of business. In the opinion of management, the outcome of such proceedings and litigation currently pending will not have a material adverse effect, if any, on the Company's Consolidated Financial Statements.

14. Short-Term Borrowings and Long-Term Debt

Short-term borrowings and long-term debt as of November 28, 2020 and May 30, 2020 consisted of the following obligations:

(In millions)	November 28, 2020		May 30, 2020
Debt securities, 6.0%, due March 1, 2021	$	50.0	$	50.0
Debt securities, 4.95%, due May 20, 2030	49.9		49.9
Syndicated revolving line of credit, due August 2024	225.0		490.0
Supplier financing program	2.3		1.4
Total debt	$	327.2	$	591.3
Less: Current debt	(52.3)		(51.4)
Long-term debt	$	274.9	$	539.9

As of May 30, 2020, the Company's syndicated revolving line of credit provided the Company with up to $500 million in revolving variable interest borrowing capacity and included an "accordion feature" allowing the Company to increase, at its option and subject to the approval of the participating banks, the aggregate borrowing capacity of the facility by up to $250 million. Outstanding borrowings bear interest at rates based on the prime rate, federal funds rate, LIBOR or negotiated rates as outlined in the agreement. Interest is payable periodically throughout the period if borrowings are outstanding.

In June 2020, the Company repaid the $265 million draw on its syndicated revolving line of credit that was taken as a precautionary measure in March 2020 to provide additional near-term liquidity given the uncertainty related to COVID-19.

Available borrowings under the syndicated revolving line of credit were as follows for the periods indicated:

(In millions)	November 28, 2020		May 30, 2020
Syndicated revolving line of credit borrowing capacity	$	500.0	$	500.0
Less: Borrowings under the syndicated revolving line of credit	225.0		490.0
Less: Outstanding letters of credit	9.8		9.4
Available borrowings under the syndicated revolving line of credit	$	265.2	$	0.6

Supplier Financing Program

The Company has an agreement with a third-party financial institution that allows certain participating suppliers the ability to finance payment obligations from the Company. Under this program, participating suppliers may finance payment obligations of the Company, prior to their scheduled due dates, at a discounted price to the third-party financial institution.

The Company has lengthened the payment terms for certain suppliers that have chosen to participate in the program. As a result, certain amounts due to suppliers have payment terms that are longer than standard industry practice and as such, these amounts have been excluded from the caption “Accounts payable” in the Condensed Consolidated Balance Sheets as the amounts have been accounted for by the Company as current debt, within the caption “Short-term borrowings and current portion of long-term debt”.

16. Operating Segments

The Company's reportable segments consist of North America Contract, International Contract, and Retail.

The North America Contract segment includes the operations associated with the design, manufacture and sale of furniture and textile products for work-related settings, including office, education, and healthcare environments, throughout the United States and Canada. The business associated with the Company's owned contract furniture dealers is also included in the North America Contract segment. In addition to the Herman Miller brand, this segment includes the operations associated with the design, manufacture and sale of high-craft furniture products and textiles including Geiger wood products, Maharam textiles, Nemschoff, naughtone and Herman Miller Collection products.

The International Contract segment includes the operations associated with the design, manufacture, and sale of furniture products, primarily for work-related settings in EMEA, Latin America and Asia-Pacific.

The Retail segment includes operations associated with the sale of modern design furnishings and accessories to third party retailers, as well as direct to consumer sales through e-commerce, direct mailing catalogs, DWR studios and HAY stores.

The Company also reports a “Corporate” category consisting primarily of unallocated expenses related to general corporate functions, including, but not limited to, certain legal, executive, corporate finance, information technology, administrative and acquisition-related costs. Management regularly reviews corporate costs and believes disclosing such information provides more visibility and transparency regarding how the chief operating decision maker reviews results of the Company. The accounting policies of the operating segments are the same as those of the Company.

17. Restructuring Expense

During the fourth quarter of fiscal 2018, the Company announced a facilities consolidation plan related to its International Contract segment. This impacted certain office and manufacturing facilities in the United Kingdom and China. The plan is expected to generate cost savings of approximately $3 million. To date, the Company recognized restructuring and impairment expenses of $5.9 million, with a net credit of $1.9 million recognized to-date in fiscal 2021 and the remainder in fiscal 2020, 2019 and 2018. These expenses related to the facilities consolidation plan, comprised primarily of an asset impairment recorded against an office building in the United Kingdom that was vacated and the consolidation of the Company's manufacturing facilities in China. No future restructuring costs related to the plan are expected as the plan is substantially complete.

The office building and related assets in China were sold in the first quarter of fiscal 2021, resulting in a gain of approximately $3.4 million. The office building and related assets in the United Kingdom were sold in the second quarter of fiscal 2021, resulting in a nominal gain. Both of these gains are included within "Restructuring expense" in the Condensed Consolidated Statements of Comprehensive Income.

In the second quarter of fiscal 2020, the North America Contract segment initiated restructuring discussions with labor unions related to its Nemschoff operation in Wisconsin. The discussions were concluded in the third quarter of fiscal 2020 and as a result, the Company anticipates the total estimated costs related to the actions will be approximately $5 million. These restructuring costs relate to potential partial outsourcing and in-sourcing strategies, long-lived asset impairments and employee-related costs. To date, the Company has recorded approximately $3.1 million in pre-tax restructuring expense related to this plan, with a net credit of $0.1 million recognized in fiscal 2021 and the remainder in fiscal 2020. The plan is expected to be completed in fiscal 2021.

In the second quarter of fiscal 2020, the Company initiated a reorganization of the Global Sales and Product teams. The reorganization activities occurred primarily in the North America business with additional costs incurred Internationally. To date, the Company has recorded a total of $2.6 million in pre-tax restructuring expense related to this plan. The reorganization is complete and no future costs related to this plan are expected.

Herman Miller, Inc. and Subsidiaries 23

In the third quarter of fiscal 2020, the Company announced a reorganization of the Retail segment's leadership team. The Company recognized pre-tax severance and employee related restructuring expense of $2.2 million related to the plan. No future restructuring costs related to the plan are expected as the plan is complete.

The following table provides an analysis of the changes in the restructuring costs reserve for the above plans for the six months ended November 28, 2020:

(In millions)	Severance and Employee-Related		Exit or Disposal Activities		Total
May 30, 2020	$	5.9	$	0.8	$	6.7
Restructuring Costs	0.1		(2.0)		$	(1.9)
Amounts Paid	(2.1)		(0.1)		$	(2.2)
Other*	$	—	$	3.4	$	3.4
November 28, 2020	$	3.9	$	2.1	$	6.0

*This represents the gain on the sale of office building and related assets in China and the United Kingdom which were recorded as restructuring cost, however, do not impact the restructuring reserve.

In the fourth quarter of fiscal 2020, the Company announced a restructuring plan (“May 2020 restructuring plan") to substantially reduce expenses in response to the impact of the COVID-19 pandemic and related restrictions. These activities included voluntary and involuntary reductions in its North American and International workforces. Combined, these actions resulted in the elimination of approximately 400 full-time positions throughout the Company in various businesses and functions. As the result of these actions, the Company projects an annualized expense reduction of approximately $40 million. To date, the Company incurred severance and related charges of $18.3 million with $3.1 million recognized in fiscal 2021 and the remainder in fiscal 2020. No material future restructuring costs related to the plan are expected as the plan is substantially complete and the remaining amounts will be paid in fiscal 2021.

The following table provides an analysis of the changes in the restructuring cost reserve for the six months ended November 28, 2020:

(In millions)	Severance and Employee-Related
May 30, 2020	$	15.3
Restructuring Costs	3.1
Amounts Paid	(16.0)
November 28, 2020	$	2.4

The following is a summary of restructuring expenses by segment for the periods indicated:

	Three Months Ended				Six Months Ended
(In millions)	November 28, 2020		November 30, 2019		November 28, 2020		November 30, 2019

International Contract	1.6		0.4		(1.2)		0.6
Total	$	2.4	$	4.2	$	1.2	$	6.1

18. Variable Interest Entities

The Company has long-term notes receivable with a third-party owned dealer that are deemed to be variable interests in a variable interest entity. The carrying value of these long-term notes receivable was $1.3 million and $1.5 million as of November 28, 2020 and May 30, 2020, respectively, and represents the Company’s maximum exposure to loss. The Company is not deemed to be the primary beneficiary of the variable interest entity as the entity controls the activities that most significantly impact the entity’s economic performance, including sales, marketing, and operations.

Item 2: Management's Discussion and Analysis of Financial Condition and Results of Operations

(Dollars in millions, except share data)

The following is management's discussion and analysis of certain significant factors that affected the Company's financial condition, earnings and cash flows during the periods included in the accompanying Condensed Consolidated Financial Statements and should be read in conjunction with the Company's Annual Report on Form 10-K for the fiscal year ended May 30, 2020. References to “Notes” are to the footnotes included in the accompanying Condensed Consolidated Financial Statements.

Business Overview

The Company researches, designs, manufactures, sells, and distributes furnishings and accessories, for use in various environments including office, healthcare, educational, and residential settings, and provides related services that support companies all over the world. The Company's products are sold primarily through independent contract office furniture dealers as well as the following channels: owned contract office furniture dealers, direct customer sales, independent retailers, owned retail studios and stores, direct-mail catalogs and the Company's e-commerce platforms. The following is a summary of results for the three months ended November 28, 2020:

•Net sales were $626.3 million and orders were $629.7 million, representing a decrease of 7.1% and 6.7%, respectively, when compared to the same quarter of the prior year. The decrease in net sales was driven primarily by decreased sales volumes in the North America Contract segment, partially offset by increased demand within the Retail segment and the acquisitions of HAY and naughtone. On an organic basis, net sales were $573.5 million(*) and orders were $572.2 million, representing a decrease of 14.9%(*) and 15.2%, respectively, when compared to the same quarter of the prior year.

•Gross margin was 39.0% as compared to 37.9% for the same quarter of the prior year. The increase in gross margin was driven primarily by favorable channel and product sales mix partially offset by lower overhead leverage due to decreased volumes.

•Operating expenses decreased by $19.9 million or 10.3% as compared to the same quarter of the prior year. The decrease in operating expenses was driven primarily by lower compensation and benefit costs, lower marketing and selling costs, and lower travel costs.

•The effective tax rate was 23.5% compared to 14.3% for the same quarter of the prior year. The same period in the prior year included a non-taxable gain on consolidation of an equity method investment which is the primary driver of the year over year increase in the effective tax rate.

•Diluted earnings per share were $0.87, a 34.1% decrease as compared to the prior year. Excluding restructuring expenses and other special charges, adjusted diluted earnings per share were $0.89(*), a 1.1% increase as compared to prior year adjusted diluted earnings per share.

(*) Non-GAAP measurements; see accompanying reconciliations and explanations.

The following summary includes the Company's view on the economic environment in which it operates:

•The Company's Retail segment supports a range of furniture categories aimed at the home environment. Several of these categories, including Upholstery, Outdoor, Storage, and Accessories, saw a ramp-up in demand during the first quarter of fiscal 2021 and this continued into the second quarter of fiscal 2021.

•The disruption from the COVID-19 pandemic adversely impacted the results of our second quarter as industry order trends, as reported by the Business and Institutional Furniture Manufacturers Association ("BIFMA"), have highlighted near-term demand pressures from the slowdown in economic activity from the pandemic in

Herman Miller, Inc. and Subsidiaries 25

our North America Contract segment. Our International Contract segment has also been impacted, though many of the markets internationally have shown signs of faster economic recovery.

•The Company is monitoring the resolution of various trade policy negotiations between the U.S. and key trading partners as well as the ongoing negotiations concerning the U.K. referendum to exit the European Union ("Brexit"). These negotiations create uncertainty in key markets, particularly the U.K., continental Europe and China, which, if unresolved in the near term, could negatively impact customer demand.

•The Company continues to navigate the impact of global tariffs. The Company believes, based upon existing circumstances, that pricing, strategic sourcing actions and profit optimization initiatives have fully offset the current level of tariffs imposed on imports from China.

•The Company's financial performance is sensitive to changes in certain input costs, including steel and steel component parts. The market price of steel in the second quarter of fiscal 2021 was lower than the same period of the prior year and favorably impacted consolidated results on a year-over-year basis. However, the price of steel increased towards the end of the quarter and has the potential to unfavorably impact consolidated gross margin in the second half of fiscal 2021.

The remaining sections within Item 2 include additional analysis of the three and six months ended November 28, 2020, including discussion of significant variances compared to the prior year periods.

COVID-19 Update

The Company continues to respond to the challenges brought about by the COVID-19 pandemic. Workplace restrictions are regionally applied based on the recommendations of local government and health authorities. While demand for the Company's products and services, particularly in the Contract channel of the business has been adversely impacted, our multi-channel go-to-market approach has enabled us to serve customers where, and how, they need to be served. In addition, the investments we’ve made in people, technology, and products has positioned us well to capitalize on emerging opportunities as our customers' needs changed quickly at the onset of the COVID-19 crisis. This has allowed for our Retail business to take advantage of the unanticipated emerging work-from-home trend as consumers are focusing on their broader home environments. Despite this, the extent of the geographic spread and duration of this virus, the impact on our supply chain, future demand for our products, and related financial impact cannot be estimated at this time with any degree of certainty.

Employee Safety and Health

The health and well-being of employees remains top of mind. We are taking a regional approach to restrictions based on active COVID-19 case levels and local health authority recommendations. Contact tracing is active in all regions to help track and control the spread of the virus. We also continue to employ a variety of other safety measures including domestic and international travel restrictions, extensive cleaning protocols, temperature and health screenings, personal protective equipment, and visitor safety guidelines.

Customer Focus

The digital investments we’ve made allowed us to pivot quickly and capitalize on a new set of opportunities when our customers’ purchasing behaviors changed. These investments include a reimagined Design Within Reach website, a Work from Home landing page on Herman Miller’s website, a Work from Home online assessment tool, and new digital platforms that are creating greater efficiencies for contract and dealer audiences. Perhaps most notable for the quarter, our first Herman Miller retail seating concept stores opened in Los Angeles and New York City. In the early days, these stores have exceeded our expectations as we seek to educate customers about the health benefits of ergonomic seating. We are uniquely positioned to serve our customers through multiple channels with the most comprehensive portfolio of products in the industry. We are confident in our ability to partner with them to solve for the next generation workplace by providing authentic modern designs for their workplaces and their homes.

26 Form 10-Q

Manufacturing and Retail Operations

Manufacturing facilities continue to operate at near-normal capacity with enhanced safety precautions. Nearly all retail studios and stores are open in some capacity; with some open to the public, some in limited capacity, and others by appointment only. All facilities operate within the context and subject to local guidance from government and health authorities and we will continue to adjust to ensure we are acting in accordance with these guidelines.

Cost Reductions

In fiscal 2020, the Company implemented a range of actions aimed at temporarily reducing costs and preserving liquidity. In fiscal 2021, the Company, together with its Board of Directors, made the decision to move forward with several restorative actions. This included eliminating the 10% reduction in compensation, the introduction of a modified bonus program and re-establishing a quarterly cash dividend program. In addition, the Company has elected to reinstate the previously suspended retirement plan contributions starting in the fourth quarter of fiscal 2021. The Company continues to tightly control operating expenses in the face of lingering economic uncertainty.

Reconciliation of Non-GAAP Financial Measures

This report contains references to organic net sales and adjusted earnings per share - diluted, which are non-GAAP financial measures. Organic growth (decline) represents the change in net sales, excluding currency translation effects and the impact of acquisitions. Adjusted earnings per share represents reported diluted earnings per share excluding the impact from adjustments related to restructuring expenses and other special charges or gains, including related taxes. Restructuring expenses in the current period included actions involving facilities consolidation and optimization and targeted workforce reductions, while in the comparative period included actions involving facilities consolidation and optimization and costs associated with an early retirement program.

The Company believes presenting organic net sales and adjusted earnings per share - diluted is useful for investors as it provides financial information on a more comparative basis for the periods presented by excluding items that are not representative of the ongoing operations of the Company.

Organic net sales and adjusted earnings per share - diluted are not measurements of our financial performance under GAAP and should not be considered as alternatives to the related GAAP measurement. These non-GAAP measurements have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. Our presentation of non-GAAP measures should not be construed as an indication that our future results will be unaffected by unusual or infrequent items. We compensate for these limitations by providing prominence of our GAAP results and using the non-GAAP financial measures only as a supplement.

The following tables reconcile net sales to organic net sales for the periods ended as indicated below:

Cash Flows - Operating Activities

Cash provided by operating activities for the six months ended November 28, 2020 was $214.6 million, as compared to $142.4 million in the same period of the prior year. The increase in cash generated from operations in the current year, compared to the prior year, was primarily due to:

•Prior year net earnings which included a non-taxable non-cash gain on consolidation of an equity method investment of $30.5 million; and

•An increase in current liabilities in the current period of $22.9 million, driven primarily by an increase in accounts payable. This compares to a decrease in current liabilities of $21.1 million in the prior year period. The decrease in the prior year period was driven primarily by a decrease in accrued liabilities; offset by

•A decrease in current assets in the current period of $2.3 million, driven by a decrease in inventory and prepaid expenses, offset by an increase in accounts receivable. This compares to a decrease in current assets of $16.5 million in the prior year period.

Cash Flows - Investing Activities

Cash used in investing activities for the six months ended November 28, 2020 was $24.4 million, as compared to $82.1 million in the same period of the prior year. The decrease in cash outflow in the current year, compared to the prior year, was primarily due to:

•Prior year cash outflow of $40.0 million for the purchase of naughtone;

•A decrease in capital expenditures of $14.2 million due to reduced spending as a result of COVID-19; and

•Proceeds from the sale of the Company's manufacturing facility in China and office facility in the United Kingdom in the current year of $11.4 million.

At the end of the second quarter of fiscal 2021, there were outstanding commitments for capital purchases of $16.3 million. The Company plans to fund these commitments through a combination of cash on hand and cash flows from operations. The Company expects full-year capital purchases to be between $50.0 million and $60.0 million, which will be primarily related to investments in the Company's facilities and equipment. This compares to full-year capital spending of $69.0 million in fiscal 2020.

Cash Flows - Financing Activities

Cash used in financing activities for the six months ended November 28, 2020 was $276.9 million, as compared to $40.6 million in the same period of the prior year. The increase in cash outflow in the current year, compared to the prior year, was primarily due to repayments of $265.0 million on the Company's credit facility in June 2020.

Sources of Liquidity

In addition to steps taken to protect its workforce and manage business operations, the Company has taken actions to safeguard its capital position in the current environment. The Company is closely managing spending levels, capital investments, and working capital, and has temporarily suspended open market share repurchase activity as part of managing cash flows. For more information on current cost reductions, refer to the COVID-19 Update section above.

At the end of the second quarter of fiscal 2021, the Company had a well-positioned balance sheet and liquidity profile. In addition to cash flows from operating activities, the Company has access to liquidity through credit facilities, cash and cash equivalents, and short-term investments. These sources have been summarized below. For additional information, refer to Note 14 to the Condensed Consolidated Financial Statements.

Herman Miller, Inc. and Subsidiaries 37

Of the cash and cash equivalents noted above at the end of the second quarter of fiscal 2021, the Company had $176.4 million of cash and cash equivalents held outside the United States. In addition, the Company had marketable securities of $7.2 million held by one of its international wholly-owned subsidiaries.

The Company’s syndicated revolving line of credit, which expires on August 28, 2024, provides the Company with up to $500 million in revolving variable interest borrowing capacity and includes an "accordion feature" allowing the Company to increase, at its option and subject to the approval of the participating banks, the aggregate borrowing capacity of the facility by up to $250 million. Outstanding borrowings bear interest at rates based on the prime rate, federal funds rate, LIBOR or negotiated rates as outlined in the agreement. Interest is payable periodically throughout the period if borrowings are outstanding.

As of November 28, 2020, the total debt outstanding related to borrowings under the syndicated revolving line of credit was $225.0 million with available borrowings against this facility of $265.2 million.

The subsidiary holding the Company's marketable securities is taxed as a United States taxpayer at the Company's election. Consequently, for tax purposes, all United States tax impacts for this subsidiary have been recorded. The Company intends to repatriate $26.7 million in cash held in certain foreign jurisdictions over the next two years and as such has recorded a deferred tax liability related to foreign withholding taxes on these future dividends received in the U.S. from foreign subsidiaries of $1.8 million. A significant portion of this cash was previously taxed under the U.S. Tax Cut and Jobs Act (TCJA) one-time U.S. tax liability on undistributed foreign earnings. The Company intends to remain indefinitely reinvested in the remaining undistributed earnings outside the U.S.

The Company believes that its financial resources will allow it to manage the impact of COVID-19 on business operations for the foreseeable future which could include materially reduced revenue and profits. The Company will continue to evaluate its financial position in light of future developments, particularly those relating to COVID-19.

Contractual Obligations

Contractual obligations associated with ongoing business and financing activities will require cash payments in future periods. A table summarizing the amounts and estimated timing of these future cash payments as of May 30, 2020 was provided in the Company's annual report on Form 10-K for the year ended May 30, 2020.

Safe Harbor Provisions

Certain statements in this filing are not historical facts but are “forward-looking statements” as defined under Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act, as amended, that are based on management’s beliefs, assumptions, current expectations, estimates, and projections about the office furniture industry, the economy, and the Company itself. Words like “anticipates,” “believes,” “confident,” “estimates,” “expects,” “forecasts,” likely,” “plans,” “projects,” and “should,” variations of such words, and similar expressions identify such forward-looking statements. These statements do not guarantee future performance and involve certain risks, uncertainties, and assumptions that are difficult to predict with regard to timing, extent, likelihood, and degree of occurrence. These risks include, without limitation, the success of our growth strategy, employment and general economic conditions, the pace of economic growth in the U.S., and in our International markets, the potential impact of changes in U.S. tax law, the increase in white collar employment, the willingness of customers to undertake capital expenditures, the types of products purchased by customers, competitive-pricing pressures, the availability and pricing of raw materials, our reliance on a limited number of suppliers, our ability to expand globally given the risks associated with regulatory and legal compliance challenges and accompanying currency fluctuations, the ability to increase prices to absorb the additional costs of raw materials, the financial strength of our dealers and the financial strength of our customers, our ability to locate new DWR, HAY, and Herman Miller retail stores and studios, negotiate favorable lease terms for new and existing locations and the implementation of our studio portfolio transformation, our ability to attract and retain key executives and other qualified employees, our ability to continue to make product innovations, the success of newly-introduced products, our ability to serve all of our markets, possible acquisitions, divestitures or alliances, the pace and level of government procurement, the outcome of pending litigation or governmental audits or investigations, political risk in the markets we serve, natural disasters, public health crises, disease outbreaks, and other risks identified in our filings with the Securities and Exchange Commission.

Item 3: Quantitative and Qualitative Disclosures About Market Risk

The information concerning quantitative and qualitative disclosures about market risk contained in the Company’s Annual Report on Form 10-K for its fiscal year ended May 30, 2020 has not changed significantly. The nature of market risks from interest rates and commodity prices has not changed materially during the first six months of fiscal 2021.

Foreign Exchange Risk

The Company primarily manufactures its products in the United States, United Kingdom, China and India. It also sources completed products and product components from outside the United States. The Company's completed products are sold in numerous countries around the world. Sales in foreign countries as well as certain expenses related to those sales are transacted in currencies other than the Company's reporting currency, the U.S. dollar. Accordingly, production costs and profit margins related to these sales are affected by the currency exchange relationship between the countries where the sales take place and the countries where the products are sourced or manufactured. These currency exchange relationships can also impact the Company's competitive positions within these markets.

In the normal course of business, the Company enters into contracts denominated in foreign currencies. The principal foreign currencies in which the Company conducts its business are the British pound sterling, euro, Canadian dollar, Japanese yen, Mexican peso, Hong Kong dollar, Chinese renminbi, and the Danish krone. Changes in the fair value of such contracts are reported in earnings in the period the value of the contract changes. The net gain or loss upon settlement and the change in fair value of outstanding contracts is recorded as a component of Other (income) expense, net.

This compares to purchases of $23.8 million and $45.7 million for the three and six months ended November 30, 2019, respectively.

During the fourth quarter of fiscal 2020, the Company determined it was more likely than not that the fair value of certain right-of-use assets were below their carrying values and assessed these assets for impairment. As result of this assessment the Company recorded an impairment of $19.3 million in the Consolidated Statements of Comprehensive Income in the fourth quarter of fiscal 2020 which is the primary driver of lower operating lease cost in the three and six months ended November 28, 2020 compared to the prior year.

At November 28, 2020, the Company had no financing leases. The undiscounted annual future minimum lease payments related to the Company's right-of-use assets are summarized by fiscal year in the following table:

Acquisitions

Acquisitions

Nine United Denmark A/S

On June 7, 2018, the Company acquired 33% of the outstanding equity of Nine United Denmark A/S, d/b/a HAY and subsequently renamed to HAY ApS ("HAY”), a Copenhagen, Denmark-based, design leader in furniture and ancillary furnishings for residential and contract markets in Europe and Asia. The Company acquired its 33% ownership interest in HAY for approximately $65.5 million in cash. The Company also acquired the rights to the HAY brand in North America under a long-term license agreement for approximately $4.8 million in cash.

On December 2, 2019, the Company obtained a controlling financial interest in HAY through the purchase of an additional 34% ownership interest. This acquisition allows the Company to further promote growth and development of HAY's ancillary product lines and continue to support product innovation and sales growth. The Company previously accounted for its ownership interest in HAY as an equity method investment, but upon increasing its ownership to 67%, the Company consolidated the operations of HAY. Total consideration paid for an additional 34% ownership interest of HAY was $79.0 million, exclusive of HAY cash on hand. The Company funded the acquisition with cash and cash equivalents.

The previously mentioned HAY long-term licensing agreement was deemed to be a contractual preexisting relationship. As a result of the business combination, the Company recorded this arrangement at its December 2, 2019 fair value,

which resulted in an increase in goodwill of $10.0 million and a net gain of approximately $6 million, which was recorded within “Gain on consolidation of equity method investments" within the Condensed Consolidated Statements of Comprehensive Income during the three months ended May 30, 2020. The goodwill was recorded within the Company’s Retail segment.

The Company is a party to options, that if exercised, would require it to purchase the remaining 33% of the equity in HAY, at fair market value. This remaining redeemable noncontrolling interest in HAY is classified outside of permanent equity in the Consolidated Balance Sheets and is carried at the current estimated redemption amount.

The allocation of the purchase price was finalized during the first quarter of fiscal 2021. The following table presents the allocation of purchase price related to acquired tangible assets:

(In millions)
Cash	$	12.1
Working capital, net of cash and inventory step-up	12.3
Net property and equipment	0.9
Other assets	3.9
Other liabilities	(3.1)
Net assets acquired	$	26.1

The purchase of the additional equity interest in HAY was considered to be an acquisition achieved in stages, whereby the previously held equity interest was remeasured as of the acquisition date. The Company considered multiple factors in determining the fair value of the previously held equity method investment, including the price negotiated with the selling shareholder for the 34% equity interest in HAY, an income valuation model (discounted cash flow) and current trading multiples for comparable companies. Based on this analysis, the Company recognized an immaterial non-taxable gain on the remeasurement of the previously held equity method investment of $67.8 million in the third quarter of fiscal 2020. The net gain has been recognized in “Gain on consolidation of equity method investments" within the Condensed Consolidated Statements of Comprehensive Income during the three months ended May 30, 2020.

The following table summarizes the acquired identified intangible assets, valuation method employed, useful lives and fair value, as determined by the Company at the acquisition date:

(In millions)	Valuation Method	Useful Life (years)	Fair Value
Inventory Step-up	Comparative Sales Approach	0.8	$	3.4

Tradename	Relief from Royalty	Indefinite	60.0
Product Development	Relief from Royalty	8.0	22.0
Customer Relationships	Multi-Period Excess Earnings	9.0	34.0
Total			$	118.9

Goodwill related to the acquisition was recorded within the International Contract segment for $101.1 million and the Retail segment for $10.0 million. Subsequent to the acquisition, the goodwill recorded to the Retail segment was fully impaired in the fourth quarter of fiscal 2020 based on the results of the Company's annual goodwill impairment assessment.

naughtone

On October 25, 2019 (“Acquisition Date”), the Company purchased the remaining 47.5% equity voting interest in naughtone (Holdings) Limited and naughtone Manufacturing Ltd. (together “naughtone”). naughtone is an upscale, contemporary furniture manufacturer based in Harrogate, North Yorkshire, UK. The completion of the acquisition allows the Company to further promote growth and development of naughtone's ancillary product lines, and continue to support product innovation and sales growth. The Company previously accounted for its ownership interest in naughtone as an equity method investment. Upon increasing its ownership to 100% on the Acquisition Date, the

Company obtained a controlling financial interest and consolidated the operations of naughtone. Total consideration paid for naughtone on the Acquisition Date was $45.9 million, exclusive of naughtone cash on hand. The Company funded the acquisition with cash and cash equivalents. The allocation of the purchase price was finalized during the fourth quarter of fiscal 2020.

The following table presents the allocation of purchase price related to acquired tangible assets:

(In millions)
Cash	$	5.1
Working capital, net of cash and inventory step-up	1.3
Net property and equipment	0.8
Net assets acquired	$	7.2

The purchase of the remaining equity interest in naughtone was considered to be an acquisition achieved in stages, whereby the previously held equity interest was remeasured as of the Acquisition Date. The Company considered multiple factors in determining the fair value of the previously held equity method investment, including the price negotiated with the selling shareholder for the 47.5% equity interest in naughtone, an income valuation model (discounted cash flow) and current trading multiples for comparable companies. Based on this analysis, the Company recognized a non-taxable gain of approximately $30 million on the remeasurement of the previously held equity method investment of $20.5 million. The net gain has been recognized in “Gain on consolidation of equity method investments" within the Condensed Consolidated Statements of Comprehensive Income during the three and six months ended November 30, 2019.

The following table summarizes the acquired identified intangible assets, valuation method employed, useful lives and fair value, as determined by the Company at the acquisition date:

Goodwill and Indefinite-lived Intangibles

Goodwill and Indefinite-Lived Intangibles

Goodwill and other indefinite-lived intangible assets included in the Condensed Consolidated Balance Sheets consisted of the following as of November 28, 2020 and May 30, 2020:

(In millions)	Goodwill		Indefinite-lived Intangible Assets
May 30, 2020	$	346.0	$	92.8
Foreign currency translation adjustments	12.5		3.6
November 28, 2020	$	358.5	$	96.4

Goodwill is tested for impairment at the reporting unit level annually, or more frequently, when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. When testing goodwill for impairment, the Company may first assess qualitative factors. If an initial qualitative assessment identifies that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, additional quantitative testing is performed. The Company may also elect to bypass the qualitative testing and proceed directly to the quantitative testing. If the quantitative testing indicates that goodwill is impaired, the carrying value of goodwill is written down to fair value.

Each of the reporting units were reviewed for impairment using a quantitative assessment as of March 31, 2020, our annual testing date. In performing the quantitative impairment test, the Company determined that the fair value of the North America and International reporting units exceeded the carrying amount and, as such, these reporting units were not impaired. The assessment of the Retail and Maharam reporting units indicated that the carrying value of these reporting units exceeded their fair values, and goodwill impairment charges of $88.8 million and $36.7 million, respectively, were recorded in the fourth quarter of fiscal 2020 resulting in no goodwill remaining in either the Retail or Maharam reporting units. Accumulated goodwill impairment losses were $125.3 million as of November 28, 2020 and May 30, 2020.

The fair value of the Company's International reporting unit, which includes $163.7 million of goodwill as of May 30, 2020, exceeded its carrying value by 17%. Due to the level that the reporting unit fair value exceeded the carrying amount and the results of the sensitivity analysis, the Company may need to record an impairment charge if the operating results of its International reporting unit were to decline in future periods.

Intangible assets with indefinite useful lives are not subject to amortization and are evaluated annually for impairment, or more frequently, when events or changes in circumstances indicate that the fair value of an intangible asset may not be recoverable.

In fiscal 2020, the Company performed quantitative assessments in testing indefinite-lived intangible assets for impairment, which resulted in the carrying values of the DWR, Maharam, HAY and naughtone trade names exceeding their fair values by $53.3 million, and impairment charges of this amount were recognized during the fourth quarter of fiscal 2020. If the residual cash flows related to these trade names were to decline in future periods, the Company may need to record an additional impairment charge.

During the six months ended November 28, 2020, there were no identified indicators of impairment that required the Company to complete an interim quantitative impairment assessment related to any of the Company's reporting units or indefinitely-lived intangible assets.

Income Taxes

The Company's process for determining the provision for income taxes for the three and six months ended November 28, 2020 involved using an estimated annual effective tax rate which was based on expected annual income and statutory tax rates across the various jurisdictions in which it operates. The effective tax rates were 23.5% and 14.3%, respectively, for the three month periods ended November 28, 2020 and November 30, 2019. The same period in the prior year included a non-taxable gain on consolidation of an equity method investment which is the primary driver of the year over year increase in the effective tax rate. For the three months ended November 28, 2020, the effective tax rate is higher than the United States federal statutory rate due to United States state income taxes and the mix of earnings in tax jurisdictions that had rates that were higher than the United States federal statutory rate. For the three months ended November 30, 2019, the effective tax rate was lower than the United States federal statutory rate mainly as a result from the impact of a non-taxable gain on consolidation of an equity method investment.

The effective tax rates were 22.6% and 16.9%, respectively, for the six month periods ended November 28, 2020 and November 30, 2019. The same period in the prior year included a non-taxable gain on consolidation of an equity method investment which is the primary driver of the year over year increase in the effective tax rate. For the six months ended November 28, 2020, the effective tax rate is higher than the United States federal statutory rate due to United States state income taxes and the mix of earnings in tax jurisdictions that had rates that were higher than the United States federal statutory rate. For the six months ended November 30, 2019, the effective tax rate was lower than the United States federal statutory rate mainly due to the non-taxed nature of the gain on consolidation of an equity method investment.

The Company recognizes interest and penalties related to uncertain tax benefits through income tax expense in its Condensed Consolidated Statements of Comprehensive Income. Interest and penalties recognized in the Company's Condensed Consolidated Statements of Comprehensive Income were negligible for the three and six months ended November 28, 2020 and November 30, 2019.

The Company's recorded liability for potential interest and penalties related to uncertain tax benefits was:

Liability for interest and penalties	$	1.0	$	0.8
Liability for uncertain tax positions, current	$	2.3	$	1.9

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 twelve months because of the audits. Tax payments related to these audits, if any, are not expected to be material to the Company's Condensed Consolidated Statements of Comprehensive Income.

For the majority of tax jurisdictions, the Company is no longer subject to state, local, or non-United States income tax examinations by tax authorities for fiscal years before 2016.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The Company's financial instruments consist of cash equivalents, marketable securities, accounts and notes receivable, deferred compensation plan, accounts payable, debt, interest rate swaps, foreign currency exchange contracts, redeemable noncontrolling interests, indefinite-lived intangible assets and right-of-use assets. The Company's financial instruments, other than long-term debt, are recorded at fair value.

The carrying value and fair value of the Company's long-term debt, including current maturities, is as follows for the periods indicated:

(In millions)	November 28, 2020		May 30, 2020
Carrying value	$	327.2	$	591.3
Fair value	$	334.4	$	594.0

The following describes the methods the Company uses to estimate the fair value of financial assets and liabilities recorded in net earnings, which have not significantly changed in the current period:

Cash and cash equivalents — The Company invests excess cash in short term investments in the form of commercial paper and money market funds. Commercial paper is valued at amortized costs while money market funds are valued using net asset value ("NAV").

Mutual Funds-equity — The Company's equity securities primarily include equity mutual funds. The equity mutual fund investments are recorded at fair value using quoted prices for similar securities.

Deferred compensation plan — The Company's deferred compensation plan primarily includes various domestic and international mutual funds that are recorded at fair value using quoted prices for similar securities.

Foreign currency exchange contracts — The Company's foreign currency exchange contracts are valued using an approach based on foreign currency exchange rates obtained from active markets. The estimated fair value of forward currency exchange contracts is based on month-end spot rates as adjusted by market-based current activity. These forward contracts are not designated as hedging instruments.

The following table sets forth financial assets and liabilities measured at fair value through net income and the respective pricing levels to which the fair value measurements are classified within the fair value hierarchy as of November 28, 2020 and May 30, 2020.

(In millions)	November 28, 2020				May 30, 2020
Financial Assets	NAV		Quoted Prices with Other Observable Inputs (Level 2)		NAV		Quoted Prices with Other Observable Inputs (Level 2)
Cash equivalents:
Money market funds	$	90.1	$	—	$	283.7	$	—
Mutual funds - equity	—		0.7		—		0.7
Foreign currency forward contracts	—		1.4		—		1.1
Deferred compensation plan	—		16.4		—		13.2
Total	$	90.1	$	18.5	$	283.7	$	15.0
Financial Liabilities
Foreign currency forward contracts	$	—	$	0.3	$	—	$	0.8
Total	$	—	$	0.3	$	—	$	0.8

The following describes the methods the Company uses to estimate the fair value of financial assets and liabilities recorded in other comprehensive income, which have not significantly changed in the current period:

Mutual funds-fixed income — The Company's fixed-income securities primarily include fixed income mutual funds and government obligations. These investments are recorded at fair value using quoted prices for similar securities.

Interest rate swap agreements — The value of the Company's interest rate swap agreements is determined using a market approach based on rates obtained from active markets. The interest rate swap agreements are designated as cash flow hedging instruments.

The following table sets forth financial assets and liabilities measured at fair value through other comprehensive income and the respective pricing levels to which the fair value measurements are classified within the fair value hierarchy as of November 28, 2020 and May 30, 2020.

(In millions)	November 28, 2020		May 30, 2020
Financial Assets	Quoted Prices with Other Observable Inputs (Level 2)		Quoted Prices with Other Observable Inputs (Level 2)
Mutual funds - fixed income	$	6.5	$	6.3
Total	$	6.5	$	6.3
Financial Liabilities
Interest rate swap agreement	$	23.5	$	25.0
Total	$	23.5	$	25.0

The following is a summary of the carrying and market values of the Company's fixed income mutual funds and equity mutual funds as of the dates indicated:

	November 28, 2020						May 30, 2020
(In millions)	Cost		Unrealized Gain/(Loss)		Market Value		Cost		Unrealized Gain/(Loss)		Market Value
Mutual funds - fixed income	$	6.4	$	0.1	$	6.5	$	6.2	$	0.1	$	6.3
Mutual funds - equity	0.5		0.2		0.7		0.6		0.1		0.7
Total	$	6.9	$	0.3	$	7.2	$	6.8	$	0.2	$	7.0

The cost of securities sold is based on the specific identification method; realized gains and losses resulting from such sales are included in the Condensed Consolidated Statements of Comprehensive Income within "Other (income) expense, net". The Company views its equity and fixed income mutual funds as available for use in its current operations. Accordingly, the investments are recorded within Current Assets within the Condensed Consolidated Balance Sheets.

Derivative Instruments and Hedging Activities

Foreign Currency Forward Contracts

The Company transacts business in various foreign currencies and has established a program that primarily utilizes foreign currency forward contracts to reduce the risks associated with the effects of certain foreign currency exposures. Under this program, the Company's strategy is to have increases or decreases in our foreign currency exposures offset by gains or losses on the foreign currency forward contracts to mitigate the risks and volatility associated with foreign currency transaction gains or losses. Foreign currency exposures typically arise from net liability or asset exposures in non-functional currencies on the balance sheets of our foreign subsidiaries. Foreign currency forward contracts generally settle within 30 days and are not used for trading purposes.

These forward contracts are not designated as hedging instruments. Accordingly, we record the fair value of these contracts as of the end of the reporting period in the Consolidated Balance Sheets with changes in fair value recorded within the Consolidated Statements of Comprehensive Income. The balance sheet classification for the fair values of these forward contracts is to Other current assets for unrealized gains and to Other accrued liabilities for unrealized losses. The Consolidated Statements of Comprehensive Income classification for the fair values of these forward contracts is to Other (income) expense, net, for both realized and unrealized gains and losses.

Interest Rate Swaps

The Company enters into interest rate swap agreements to manage its exposure to interest rate changes and its overall cost of borrowing. The Company's interest rate swap agreements were entered into to exchange variable rate interest payments for fixed rate payments over the life of the agreement without the exchange of the underlying notional amounts. The notional amount of the interest rate swap agreements is used to measure interest to be paid or received. The differential paid or received on the interest rate swap agreements is recognized as an adjustment to interest expense.

The interest rate swaps were designated cash flow hedges at inception and the facts and circumstances of the hedged relationship remains consistent with the initial quantitative effectiveness assessment in that the hedged instruments remain an effective accounting hedge as of November 28, 2020. Since a designated derivative meets hedge accounting criteria, the fair value of the hedge is recorded in the Consolidated Statements of Stockholders’ Equity as a component of Accumulated other comprehensive loss, net of tax. The ineffective portion of the change in fair value of the derivatives is immediately recognized in earnings. The interest rate swap agreements are assessed for hedge effectiveness on a quarterly basis.

As of November 28, 2020, the Company had the following two outstanding interest rate swap agreements:

(In millions)	Notional Amount		Forward Start Date	Termination Date	Effective Fixed Interest Rate
September 2016 Interest Rate Swap	$	150.0	January 3, 2018	January 3, 2028	1.949	%
June 2017 Interest Rate Swap	$	75.0	January 3, 2018	January 3, 2028	2.387	%

The swaps above effectively converted indebtedness anticipated to be borrowed on the Company's revolving line of credit up to the notional amounts from a LIBOR-based floating interest rate plus applicable margin to an effective fixed interest rate plus applicable margin under the agreements as of the forward start date.

As of November 28, 2020, the fair value of the Company’s two outstanding interest rate swap agreements was a liability of $23.5 million. The liability fair value was recorded within "Other liabilities" within the Condensed Consolidated Balance Sheets.

The following table summarizes the effects of the interest rate swap agreements for the three and six months ended:

	Three Months Ended				Six Months Ended
(In millions)	November 28, 2020		November 30, 2019		November 28, 2020		November 30, 2019
Gain (loss) recognized in Other comprehensive loss (effective portion)	$	0.9	$	3.4	$	1.2	$	(5.3)
(Loss) gain reclassified from Accumulated other comprehensive loss into earnings	$	(1.1)	$	—	$	(2.2)	$	0.1

There were no gains or losses recognized in earnings for hedge ineffectiveness for the three and six month periods ended November 28, 2020 and November 30, 2019, respectively. The amount of loss expected to be reclassified from Accumulated other comprehensive loss into earnings during the next twelve months is $4.4 million, and net of tax is $3.3 million.

Redeemable Noncontrolling Interests

Changes in the Company's redeemable noncontrolling interest in HAY for the six months ended November 28, 2020 are as follows:

(In millions)	November 28, 2020
Beginning Balance	$	50.4

Commitments and Contingencies

Product Warranties

The Company provides coverage to the end-user for parts and labor on products sold under its warranty policy and for other product-related matters. The standard length of warranty is 12 years for the majority of products sold; however, this varies depending on the product classification. The Company does not sell or otherwise issue warranties or warranty extensions as stand-alone products. Reserves have been established for various costs associated with the Company's warranty program. General warranty reserves are based on historical claims experience and other currently available information and are periodically adjusted for business levels and other factors. Specific reserves are established once an issue is identified with the amounts for such reserves based on the estimated cost of correction. The Company provides an assurance-type warranty that ensures that products will function as intended. As such, the Company's estimated warranty obligation is accounted for as a liability and is recorded within current and long-term liabilities within the Condensed Consolidated Balance Sheets.

Changes in the warranty reserve for the stated periods were as follows:

	Three Months Ended				Six Months Ended
(In millions)	November 28, 2020		November 30, 2019		November 28, 2020		November 30, 2019

Accrual Balance — ending	$	59.8	$	54.6	$	59.8	$	54.6

Guarantees

The Company is periodically required to provide performance bonds to do business with certain customers. These arrangements are common in the industry and generally have terms ranging between one year and three years. The bonds are required to provide assurance to customers that the products and services they have purchased will be installed and/or provided properly and without damage to their facilities. The bonds are provided by various bonding agencies. However, the Company is ultimately liable for claims that may occur against them. As of November 28, 2020, the Company had a maximum financial exposure related to performance bonds totaling approximately $5.5 million. The Company has no history of claims, nor is it aware of circumstances that would require it to pay, under any of these arrangements. The Company also believes that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially affect the Company's Consolidated Financial Statements. Accordingly, no liability has been recorded in respect to these bonds as of either November 28, 2020 or May 30, 2020.

The Company has entered into standby letter of credit arrangements for purposes of protecting various insurance companies and lessors against default on insurance premium and lease payments. As of November 28, 2020, the Company had a maximum financial exposure from these standby letters of credit totaling approximately $9.8 million, all of which is considered usage against the Company's revolving line of credit. The Company has no history of claims, nor is it aware of circumstances that would require it to perform under any of these arrangements and believes that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially

affect the Company's Consolidated Financial Statements. Accordingly, no liability has been recorded in respect to these arrangements as of November 28, 2020 and May 30, 2020.

Contingencies

The Company is also involved in legal proceedings and litigation arising in the ordinary course of business. In the opinion of management, the outcome of such proceedings and litigation currently pending will not have a material adverse effect, if any, on the Company's Consolidated Financial Statements.

As of May 30, 2020, the Company's syndicated revolving line of credit provided the Company with up to $500 million in revolving variable interest borrowing capacity and included an "accordion feature" allowing the Company to increase, at its option and subject to the approval of the participating banks, the aggregate borrowing capacity of the facility by up to $250 million. Outstanding borrowings bear interest at rates based on the prime rate, federal funds rate, LIBOR or negotiated rates as outlined in the agreement. Interest is payable periodically throughout the period if borrowings are outstanding.

In June 2020, the Company repaid the $265 million draw on its syndicated revolving line of credit that was taken as a precautionary measure in March 2020 to provide additional near-term liquidity given the uncertainty related to COVID-19.

Available borrowings under the syndicated revolving line of credit were as follows for the periods indicated:

Less: Outstanding letters of credit	9.8		9.4
Available borrowings under the syndicated revolving line of credit	$	265.2	$	0.6

Supplier Financing Program

The Company has an agreement with a third-party financial institution that allows certain participating suppliers the ability to finance payment obligations from the Company. Under this program, participating suppliers may finance payment obligations of the Company, prior to their scheduled due dates, at a discounted price to the third-party financial institution.

The Company has lengthened the payment terms for certain suppliers that have chosen to participate in the program. As a result, certain amounts due to suppliers have payment terms that are longer than standard industry practice and as such, these amounts have been excluded from the caption “Accounts payable” in the Condensed Consolidated Balance Sheets as the amounts have been accounted for by the Company as current debt, within the caption “Short-term borrowings and current portion of long-term debt”.

Operating Segments

Operating Segments

The Company's reportable segments consist of North America Contract, International Contract, and Retail.

The North America Contract segment includes the operations associated with the design, manufacture and sale of furniture and textile products for work-related settings, including office, education, and healthcare environments, throughout the United States and Canada. The business associated with the Company's owned contract furniture dealers is also included in the North America Contract segment. In addition to the Herman Miller brand, this segment includes the operations associated with the design, manufacture and sale of high-craft furniture products and textiles including Geiger wood products, Maharam textiles, Nemschoff, naughtone and Herman Miller Collection products.

Restructuring and Related Activities [Abstract]

Restructuring Expense

Restructuring Expense

During the fourth quarter of fiscal 2018, the Company announced a facilities consolidation plan related to its International Contract segment. This impacted certain office and manufacturing facilities in the United Kingdom and China. The plan is expected to generate cost savings of approximately $3 million. To date, the Company recognized restructuring and impairment expenses of $5.9 million, with a net credit of $1.9 million recognized to-date in fiscal 2021 and the remainder in fiscal 2020, 2019 and 2018. These expenses related to the facilities consolidation plan, comprised primarily of an asset impairment recorded against an office building in the United Kingdom that was vacated and the consolidation of the Company's manufacturing facilities in China. No future restructuring costs related to the plan are expected as the plan is substantially complete.

The office building and related assets in China were sold in the first quarter of fiscal 2021, resulting in a gain of approximately $3.4 million. The office building and related assets in the United Kingdom were sold in the second quarter of fiscal 2021, resulting in a nominal gain. Both of these gains are included within "Restructuring expense" in the Condensed Consolidated Statements of Comprehensive Income.

In the second quarter of fiscal 2020, the North America Contract segment initiated restructuring discussions with labor unions related to its Nemschoff operation in Wisconsin. The discussions were concluded in the third quarter of fiscal 2020 and as a result, the Company anticipates the total estimated costs related to the actions will be approximately $5 million. These restructuring costs relate to potential partial outsourcing and in-sourcing strategies, long-lived asset impairments and employee-related costs. To date, the Company has recorded approximately $3.1 million in pre-tax restructuring expense related to this plan, with a net credit of $0.1 million recognized in fiscal 2021 and the remainder in fiscal 2020. The plan is expected to be completed in fiscal 2021.

In the second quarter of fiscal 2020, the Company initiated a reorganization of the Global Sales and Product teams. The reorganization activities occurred primarily in the North America business with additional costs incurred Internationally. To date, the Company has recorded a total of $2.6 million in pre-tax restructuring expense related to this plan. The reorganization is complete and no future costs related to this plan are expected.

In the third quarter of fiscal 2020, the Company announced a reorganization of the Retail segment's leadership team. The Company recognized pre-tax severance and employee related restructuring expense of $2.2 million related to the plan. No future restructuring costs related to the plan are expected as the plan is complete.

The following table provides an analysis of the changes in the restructuring costs reserve for the above plans for the six months ended November 28, 2020:

(In millions)	Severance and Employee-Related		Exit or Disposal Activities		Total
May 30, 2020	$	5.9	$	0.8	$	6.7
Restructuring Costs	0.1		(2.0)		$	(1.9)

*This represents the gain on the sale of office building and related assets in China and the United Kingdom which were recorded as restructuring cost, however, do not impact the restructuring reserve.

In the fourth quarter of fiscal 2020, the Company announced a restructuring plan (“May 2020 restructuring plan") to substantially reduce expenses in response to the impact of the COVID-19 pandemic and related restrictions. These activities included voluntary and involuntary reductions in its North American and International workforces. Combined, these actions resulted in the elimination of approximately 400 full-time positions throughout the Company in various businesses and functions. As the result of these actions, the Company projects an annualized expense reduction of approximately $40 million. To date, the Company incurred severance and related charges of $18.3 million with $3.1 million recognized in fiscal 2021 and the remainder in fiscal 2020. No material future restructuring costs related to the plan are expected as the plan is substantially complete and the remaining amounts will be paid in fiscal 2021.

The following table provides an analysis of the changes in the restructuring cost reserve for the six months ended November 28, 2020:

On May 31, 2020, the Company adopted Accounting Standards Update ("ASU") No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" using the modified retrospective method. This update replaces the existing incurred loss impairment model with an expected loss model and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates including customer credit quality, historical write-off trends and general information regarding industry trends and the macroeconomic environment. The adoption did not have a material impact on the Company's financial statements, accounting policies or methods utilized to determine the allowance for doubtful accounts.

On May 31, 2020, the Company adopted ASU No. 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement" using the prospective method. This update modifies certain disclosure requirements for fair value measurements. The adoption did not have a material impact on the Company's financial statements.

Fair Value Measurements (Policies)

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments, Policy

The cost of securities sold is based on the specific identification method; realized gains and losses resulting from such sales are included in the Condensed Consolidated Statements of Comprehensive Income within "Other (income) expense, net".

Marketable Securities, Policy

The Company views its equity and fixed income mutual funds as available for use in its current operations. Accordingly, the investments are recorded within Current Assets within the Condensed Consolidated Balance Sheets.

Derivatives, Methods of Accounting, Hedging Derivatives, Policy

Foreign Currency Forward Contracts

The Company transacts business in various foreign currencies and has established a program that primarily utilizes foreign currency forward contracts to reduce the risks associated with the effects of certain foreign currency exposures. Under this program, the Company's strategy is to have increases or decreases in our foreign currency exposures offset by gains or losses on the foreign currency forward contracts to mitigate the risks and volatility associated with foreign currency transaction gains or losses. Foreign currency exposures typically arise from net liability or asset exposures in non-functional currencies on the balance sheets of our foreign subsidiaries. Foreign currency forward contracts generally settle within 30 days and are not used for trading purposes.

These forward contracts are not designated as hedging instruments. Accordingly, we record the fair value of these contracts as of the end of the reporting period in the Consolidated Balance Sheets with changes in fair value recorded within the Consolidated Statements of Comprehensive Income. The balance sheet classification for the fair values of these forward contracts is to Other current assets for unrealized gains and to Other accrued liabilities for unrealized losses. The Consolidated Statements of Comprehensive Income classification for the fair values of these forward contracts is to Other (income) expense, net, for both realized and unrealized gains and losses.

Interest Rate Swaps

The Company enters into interest rate swap agreements to manage its exposure to interest rate changes and its overall cost of borrowing. The Company's interest rate swap agreements were entered into to exchange variable rate interest payments for fixed rate payments over the life of the agreement without the exchange of the underlying notional amounts. The notional amount of the interest rate swap agreements is used to measure interest to be paid or received. The differential paid or received on the interest rate swap agreements is recognized as an adjustment to interest expense.

The interest rate swaps were designated cash flow hedges at inception and the facts and circumstances of the hedged relationship remains consistent with the initial quantitative effectiveness assessment in that the hedged instruments remain an effective accounting hedge as of November 28, 2020. Since a designated derivative meets hedge accounting criteria, the fair value of the hedge is recorded in the Consolidated Statements of Stockholders’ Equity as a component of Accumulated other comprehensive loss, net of tax. The ineffective portion of the change in fair value of the derivatives is immediately recognized in earnings. The interest rate swap agreements are assessed for hedge effectiveness on a quarterly basis.
