Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting and Reporting Policies The following is a summary of significant accounting and reporting policies not reflected elsewhere in the accompanying financial statements. Principles of Consolidation The Consolidated Financial Statements include the accounts of Herman Miller, Inc. and its majority-owned domestic and foreign subsidiaries. The consolidated entities are collectively referred to as “the company.” All intercompany accounts and transactions have been eliminated in the Consolidated Financial Statements. Nonconsolidated affiliates (20-50 percent owned companies) are accounted for using the equity method. Description of Business The company researches, designs, manufactures, sells, and distributes interior furnishings, 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 the company's e-commerce platforms. Fiscal Year The company's fiscal year ends on the Saturday closest to May 31. The fiscal years ended May 28, 2016 , May 30, 2015 , and May 31, 2014 each contain 52 weeks . Foreign Currency Translation The functional currency for most of the foreign subsidiaries is their local currency. The cumulative effects of translating the balance sheet accounts from the functional currency into the United States dollar using fiscal year-end exchange rates and translating revenue and expense accounts using average exchange rates for the period is reflected as a component of “Accumulated other comprehensive loss” in the Consolidated Balance Sheets. The financial statement impact of remeasuring all foreign currency transactions into the appropriate functional currency resulted in a net loss of $0.7 million , $2.1 million , and $1.2 million for the fiscal years ended May 28, 2016, May 30, 2015, and May 31, 2014, respectively. These amounts are included in “Other, net” in the Consolidated Statements of Comprehensive Income. Cash Equivalents The company holds cash equivalents as part of its cash management function. Cash equivalents include money market funds, time deposit investments, and treasury bills with original maturities of less than three months. The carrying value of cash equivalents, which approximates fair value, totaled $7.5 million an d $9.1 million as of May 28, 2016 and May 30, 2015 , respectively. All cash equivalents are high-credit quality financial instruments, and the amount of credit exposure to any one financial institution or instrument is limited. Marketable Securities The company maintains a portfolio of marketable securities primarily comprised of mutual funds. These investments are held by the company's wholly owned insurance captive and are considered “available-for-sale” securities. Accordingly, they have been recorded at fair value based on quoted market prices, with the resulting net unrealized holding gains or losses reflected net of tax as a component of “Accumulated other comprehensive loss” in the Consolidated Balance Sheets. All marketable security transactions are recognized on the trade date. Realized gains and losses on disposal of available-for-sale investments are included in “Interest and other investment income” in the Consolidated Statements of Comprehensive Income. See Note 11 of the Consolidated Financial Statements for additional disclosures of marketable securities. Accounts Receivable Allowances Reserves for uncollectible accounts receivable balances are based on known customer exposures, historical credit experience, and the specific identification of other potentially uncollectible accounts. Balances are written off against the reserve once the company determines the probability of collection to be remote. The company generally does not require collateral or other security on trade accounts receivable. Concentrations of Credit Risk Our trade receivables are primarily due from independent dealers who, in turn, carry receivables from their customers. We monitor and manage the credit risk associated with individual dealers and direct customers where applicable. Dealers are responsible for assessing and assuming credit risk of their customers and may require their customers to provide deposits, letters of credit, or other credit enhancement measures. Some sales contracts are structured such that the customer payment or obligation is direct to us. In those cases, we may assume the credit risk. Whether from dealers or customers, our trade credit exposures are not concentrated with any particular entity. Inventories Inventories are valued at the lower of cost or market and include material, labor, and overhead. Inventory cost is determined using the last-in, first-out (LIFO) method at manufacturing facilities in Michigan, whereas inventories of the company's other locations are valued using the first-in, first-out (FIFO) method. The company establishes reserves for excess and obsolete inventory based on prevailing circumstances and judgment for consideration of current events, such as economic conditions, that may affect inventory. The reserve required to record inventory at lower of cost or market may be adjusted in response to changing conditions. Further information on the company's recorded inventory balances can be found in Note 3 of the Consolidated Financial Statements. Property, Equipment, and Depreciation Property and equipment are stated at cost. The cost is depreciated over the estimated useful lives of the assets using the straight-line method. Estimated useful lives range from 3 to 10 years for machinery and equipment and do not exceed 40 years for buildings. Leasehold improvements are depreciated over the lesser of the lease term or the useful life of the asset. We capitalize certain costs incurred in connection with the development, testing, and installation of software for internal use. Software for internal use is included in property and equipment and is depreciated over an estimated useful life not exceeding 5 years . Depreciation and amortization expense is included in the Consolidated Statements of Comprehensive Income in the "Cost of sales", "Selling, general and administrative", and "Design and research" line items. As of the end of fiscal 2016 , outstanding commitments for future capital purchases approximated $14.0 million . Goodwill and Indefinite-lived Intangible Assets 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. A reporting unit is defined as an operating segment or one level below an operating segment. 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 skip 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. To estimate the fair value of each reporting unit the company utilizes a weighting of the income method and the market method. The income method is based on a discounted future cash flow approach that uses a number of estimates, including revenue based on assumed growth rates, estimated costs, and discount rates based on the reporting unit's weighted average cost of capital. Growth rates for each reporting unit are estimated based on internal estimates, historical data, and external sources. The growth estimates are also used in planning for our long-term and short-term business planning and forecasting. We test the reasonableness of the inputs and outcomes of our discounted cash flow analysis against comparable market data. The market method is based on financial multiples of companies comparable to each reporting unit and applies a control premium. The carrying value of each reporting unit represents the assignment of various assets and liabilities, excluding corporate assets and liabilities, such as cash, investments, and debt. 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. The company utilizes the relief from royalty methodology to test for impairment. The primary assumptions for the relief from royalty method include revenue forecasts, royalty rates, and discount rates. The company measures and records an impairment loss for the excess of the carrying value of the asset over its fair value. The company's indefinite-lived intangible assets consist of certain trade names valued at approximately $85.2 million as of the end of both fiscal year 2016 and 2015 . These assets have indefinite useful lives. The company recognized asset impairment expense totaling $10.8 million associated with the POSH trade name for the fiscal year 2015, which was recorded within the "Corporate" category within segment reporting. The POSH trade name asset is included within the ELA Furniture Solutions segment and as of the end of fiscal 2015, the carrying value was zero. During the fiscal year 2014, the company recorded impairment expenses of $21.4 million associated with the Nemschoff and POSH trade names. These impairment expenses are recorded in the "Restructuring and impairment expenses" line item within the Consolidated Statements of Comprehensive Income and are included in the "Corporate" category within the segment reporting. The trade name assets represent level 3 fair value measurements and these assets are recorded at fair value only if an impairment charge is recognized. Goodwill and other indefinite-lived assets included in the Consolidated Balance Sheets consist of the following: (In millions) Goodwill Indefinite-lived Intangible Assets Total Goodwill and Indefinite-lived Intangible Assets Balance, May 31, 2014 228.2 40.9 269.1 Foreign currency translation adjustments (0.7 ) — (0.7 ) DWR Acquisition 75.6 55.1 130.7 Impairment charges — (10.8 ) (10.8 ) Balance, May 30, 2015 $ 303.1 $ 85.2 $ 388.3 Foreign currency translation adjustments (0.4 ) — (0.4 ) Sale of owned dealer (0.6 ) — (0.6 ) Acquisition of George Nelson Bubble Lamp product line 3.2 — 3.2 Balance, May 28, 2016 305.3 85.2 390.5 Goodwill and indefinite-lived intangible assets stemming from the acquisition of Design Within Reach ("DWR") in fiscal 2015 and the George Nelson Bubble Lamp Product Line in fiscal 2016 are included within the Consumer reportable segment. Long-Lived Assets The company reviews other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or an asset group may not be recoverable. Each impairment test is based on a comparison of the carrying amount of the asset or asset group to the future undiscounted net cash flows expected to be generated by the asset or asset group, or in some cases, by prices for similar assets. If such assets are considered to be impaired, the impairment amount to be recognized is the amount by which the carrying value of the assets exceeds their fair value. Impairment expense of $4.0 million was recording during fiscal 2014 related to property in Ningbo, China. This was due to the acquisition of manufacturing-related assets, including a production facility and related equipment, in Dongguan, China, and as a result, the company decided not to pursue the construction of a new manufacturing and distribution facility on the previously acquired property in Ningbo. The company evaluated the fair value of this property and recorded an asset impairment equal to the excess of carrying value over fair value. This impairment charge was recorded in "Restructuring and impairment expenses", classified in the "Corporate" category for segment reporting purposes, and represents a level 3 fair value measurement. During the third quarter of fiscal 2015, the company entered into an agreement for the sale of the property in Ningbo, China, and subsequent to the end of fiscal 2015, the company completed the sale of the Ningbo property for cash consideration of approximately $4.2 million . Amortizable intangible assets within "Other amortizable intangibles, net" in the Consolidated Balance Sheets consist primarily of patents, trademarks, and customer relationships. The "customer relationships" intangible asset is comprised of relationships with customers and specifiers and networks and relationships with dealers and distributors. Refer to the following table for the combined gross carrying value and accumulated amortization for these amortizable intangibles. May 28, 2016 (In millions) Patent and Trademarks Customer Relationships Other Total Gross carrying value $ 19.8 $ 55.7 $ 7.5 $ 83.0 Accumulated amortization 12.3 15.9 4.0 32.2 Net $ 7.5 $ 39.8 $ 3.5 $ 50.8 May 30, 2015 Patent and Trademarks Customer Relationships Other Total Gross carrying value $ 18.8 $ 55.3 $ 5.0 $ 79.1 Accumulated amortization 11.7 12.0 3.1 26.8 Net $ 7.1 $ 43.3 $ 1.9 $ 52.3 The company amortizes these assets over their remaining useful lives using the straight-line method over periods ranging from 1.5 years to 20 years or on an accelerated basis to reflect the expected realization of the economic benefits. It is estimated that the weighted-average remaining useful life of patents and trademarks is approximately 5.5 years and the weighted-average remaining useful life of customer relationships is 10 years . Estimated amortization expense on existing amortizable intangible assets as of May 28, 2016 , for each of the succeeding five fiscal years is as follows: (In millions) 2017 $ 6.3 2018 $ 6.3 2019 $ 5.7 2020 $ 5.7 2021 $ 5.7 Self-Insurance The company is partially self-insured for general liability, workers' compensation, and certain employee health and dental benefits under insurance arrangements that provide for third-party coverage of claims exceeding the company's loss retention levels. The company's health benefit retention levels do not include an aggregate stop loss policy. The company's retention levels designated within significant insurance arrangements as of May 28, 2016 , ar e as follows: (In millions) Retention Level (per occurrence) General liability and auto liability/physical damage $ 1.00 Workers' compensation and property $ 0.75 The company accrues for its self-insurance arrangements based on actuarially-determined liabilities, which are recorded in “Other liabilities” in the Consolidated Balance Sheets. The value of the liability as of May 28, 2016 and May 30, 2015 was $10.6 million and $9.5 million , respectively. The actuarial valuations are based on historical information along with certain assumptions about future events. Changes in assumptions for such matters as legal actions, medical costs, and changes in actual experience could cause these estimates to change. The general and workers' compensation liabilities are managed through the company's wholly-owned insurance captive. Redeemable Noncontrolling Interests Certain minority shareholders in the company's subsidiary Herman Miller Consumer Holdings, Inc. have the right, at specified times over a period of five years, to require the company to acquire portions of their ownership interest in those entities at fair value. Their interests in these subsidiaries are classified outside permanent equity in the Consolidated Balance Sheets and are carried at the current estimated redemption amounts. The redemption amounts have been estimated based on the fair value of the subsidiary, which was determined based on a weighting of the discounted cash flow and market methods. The discounted cash flow analysis used the present value of projected cash flows and a residual value. To determine the discount rate for the discounted cash flow method, a market-based approach was used to select the discount rates used. Market multiples for comparable companies were used for the market method of valuation. The fair value of the subsidiary is sensitive to changes in projected revenues and costs, the discount rate, and the forward multiples of the comparable companies. Changes in the estimated redemption amounts of the noncontrolling interests, subject to put options, are reflected at each reporting period with a corresponding adjustment to Retained earnings. Future reductions in the carrying amounts are subject to a “floor” amount that is equal to the fair value of the redeemable noncontrolling interests at the time they were originally recorded. See Note 16 - Redeemable Noncontrolling Interests for additional information. Research, Development, and Other Related Costs Research, development, pre-production, and start-up costs are expensed as incurred. Research and development ("R&D") costs consist of expenditures incurred during the course of planned research and investigation aimed at discovery of new knowledge useful in developing new products or processes. R&D costs also include the significant enhancement of existing products or production processes and the implementation of such through design, testing of product alternatives, or construction of prototypes. R&D costs included in “Design and research” expense in the accompanying Consolidated Statements of Comprehensive Income are $62.4 million , $56.7 million , and $53.9 million , in fiscal 2016 , 2015 , and 2014 , respectively. Royalty payments made to designers of the company's products as the products are sold are a variable cost based on product sales. These expenses totaled $14.7 million , $14.7 million , and $12.0 million in fiscal years 2016 , 2015 , and 2014 respectively. They are included in "Design and research" expense in the accompanying Consolidated Statements of Comprehensive Income . Customer Payments and Incentives We offer various sales incentive programs to our customers, such as rebates and discounts. Programs such as rebates and discounts are adjustments to the selling price and are therefore characterized as a reduction to net sales. Revenue Recognition The company recognizes revenue on sales through its network of independent contract furniture dealers and independent retailers once the related product is shipped and title passes. In situations where products are sold through subsidiary dealers or directly to the end customer, revenue is recognized once the related product is shipped to the end customer and installation, if applicable, is substantially complete. Offers such as rebates and discounts are recorded as reductions to net sales. Unearned revenue occurs during the normal course of business due to advance payments from customers for future delivery of products and services. In addition to independent retailers, the company also sells product through owned retail channels, including e-commerce and DWR retail studios. These sales may include provisions involving a right of return. The company reduces revenue for an estimate of potential future product returns related to current period product revenue. When developing the allowance for sales returns, the company considers historical returns and current economic trends. Shipping and Handling Expenses The company records shipping and handling related expenses under the caption “Cost of sales” in the Consolidated Statements of Comprehensive Income. Cost of Sales We include material, labor, and overhead in cost of sales. Included within these categories are items such as freight charges, warehousing costs, internal transfer costs, and other costs of our distribution network. Selling, General, and Administrative We include costs not directly related to the manufacturing of our products in the "Selling, general, and administrative" line item within the Consolidated Statements of Comprehensive Income. Included in these expenses are items such as compensation expense, rental expense, warranty expense, and travel and entertainment expense. Income Taxes Deferred tax assets and liabilities are recognized for the expected future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. The company's annual effective tax rate is based on income, statutory tax rates, and tax planning strategies available in the various jurisdictions the company operates. Complex tax laws can be subject to different interpretations by the company and the respective government authorities. Significant judgment is required in evaluating tax positions and determining our tax expense. Tax positions are reviewed quarterly and tax assets and liabilities are adjusted as new information becomes available. In evaluating the company's ability to recover deferred tax assets within the jurisdiction from which they arise, the company considers all positive and negative evidence. These assumptions require significant judgment about forecasts of future taxable income. Stock-Based Compensation The company has several stock-based compensation plans, which are described in Not e 9 of the Consolidated Financial Statements. Our policy is to expense stock-based compensation using the fair-value based method of accounting for all awards granted. Earnings per Share Basic earnings per share (EPS) excludes the dilutive effect of common shares that could potentially be issued, due to the exercise of stock options or the vesting of restricted shares, and is computed by dividing net earnings by the weighted-average number of common shares outstanding for the period. Diluted EPS is computed by dividing net earnings by the sum of the weighted-averag e number of shares outstanding, plus all dilutive shares that could potentially be issued. The company also evaluates the impact on EPS of all participating securities under the two-class method. Refer to Note 8 of the Consolidated Financial Statements fo r further information regarding the computation of EPS. Comprehensive Income Comprehensive income consists of net earnings, foreign currency translation adjustments, unrealized holding gain (loss) on available-for-sale securities and pension liability adjustments. Refer to Note 15 of the Consolidated Financial Statements fo r further information regarding comprehensive income. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Fair Value The company classifies and discloses its fair value measurements in one of the following three categories: • Level 1 — Financial instruments with unadjusted, quoted prices listed on active market exchanges. • Level 2 — Financial instruments lacking unadjusted, quoted prices from active market exchanges, including over-the-counter traded financial instruments. Financial instrument values are determined using prices for recently traded financial instruments with similar underlying terms and direct or indirect observational inputs, such as interest rates and yield curves at commonly quoted intervals. • Level 3 — Financial instruments not actively traded on a market exchange and there is little, if any, market activity. Values are determined using significant unobservable inputs or valuation techniques. See Note 11 of the Consolidated Financial Statements for the required fair value disclosures. Foreign Currency Forward Contracts Not Designated as Hedges The company transacts business in various foreign currencies and has established a program that primarily utilizes foreign currency forward contracts to offset 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. These foreign currency exposures typically arise from net liability or asset exposures in non-functional currencies on the balance sheets of our foreign subsidiaries. These 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 expenses (income): Other, net", for both realized and unrealized gains and losses. The notional amounts of the forward contracts held to purchase and sell U.S. dollars in exchange for other major international currencies were $64.3 million and $34.7 million as of May 28, 2016 and May 30, 2015 , respectively. The notional amounts of the foreign currency forward contracts held to purchase and sell British pound sterling in exchange for other major international currencies were £31.2 million and £18.0 million as of May 28, 2016 and May 30, 2015 , respectively . The company also has other forward contracts related to other currency pairs at varying notional amounts. The effects of derivative instruments on the consolidated financial statements were as follows for the fiscal years ended 2016 and 2015 (amounts presented exclude any income tax effects): Fair Value of Derivative Instruments in Consolidated Balance Sheets (In millions) Balance Sheet Location May 28, 2016 May 30, 2015 Foreign currency forward contracts Current Assets: Other $ 0.5 $ 0.7 Foreign currency forward contracts Current Liabilities: Other Accrued Liabilities $ 0.8 $ 0.2 Effects of Derivative Instruments on Income (In millions) Fiscal Year Statement of Comprehensive Income Location May 28, 2016 May 30, 2015 May 31, 2014 (Gain)/loss recognized on foreign currency forward contracts Other expenses (income): Other, net $ (0.7 ) $ (2.1 ) $ (0.1 ) New Accounting Standards Recently Adopted Accounting Standards Standard Description Date of Adoption Effect on the Financial Statements or Other Significant Matters Balance Sheet Classification of Deferred Taxes The standard requires that deferred tax liabilities and assets, as well as any related valuation allowance, be classified as non-current in a classified statement of financial position. November 28, 2015 The company adopted the accounting standard prospectively beginning in the second quarter of fiscal 2016. As such, the prior period was not retrospectively adjusted. As of November 28, 2015 and forward, deferred tax liabilities and assets are presented as non-current. Recently Issued Accounting Standards Not Yet Adopted Standard Description Effective Date Effect on the Financial Statements or Other Significant Matters Simplifying the Measurement of Inventory Under the updated standard, an entity should measure inventory that is measured using either the first-in, first-out ("FIFO") or average cost methods at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The updated standard should be applied prospectively. June 4, 2017 The company is currently evaluating the impact of adopting this guidance. Improvements to Employee Share-Based Payment Accounting The standard simplifies several aspects of the accounting for share-based payment awards to employees, including the accounting for income taxes, forfeitures, statutory tax withholding requirements and classification in the statement of cash flows. Different adoption methodologies exist (retrospectively, modified-retrospectively, or prospectively) for the various different features of the standard being updated. June 4, 2017 The company is currently evaluating the impact of adopting this guidance. Revenue from Contracts with Customers The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard is designed to create greater comparability for financial statement users across industries and jurisdictions and also requires enhanced disclosures. The standard allows for two adoption methods, a full retrospective or modified retrospective approach. June 3, 2018 The company is currently evaluating the possible adoption methodologies and the implications of adoption on the consolidated financial statements. Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities The standard provides guidance for the measurement, presentation and disclosure of financial assets and liabilities. The standard requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any change in fair value in net income. The standard does not permit early adoption and at adoption a cumulative-effect adjustment to beginning retained earnings should be recorded. June 3, 2018 The company is currently evaluating the impact of adopting this guidance. Leases Under the updated standard a lessee's rights and obligations under most leases, including existing and new arrangements, would be recognized as assets and liabilities, respectively, on the balance sheet. The standard must be adopted under a modified retrospective approach and early adoption is permitted. June 2, 2019 The standard is expected to have a significant impact on our Consolidated Financial Statements, however the company is currently evaluating the impact. Correction of Immaterial Error In the second quarter of fiscal 2016, the company made an adjustment to correct an immaterial error related to the accrual for product warranties. As a result of this correction, the company adjusted Accrued warranty, Other noncurrent assets (to capture the impact of adjusting deferred taxes), and Retained earnings by $12.5 million , $4.7 million , and $7.8 million , respectively. The adjustment impacts the Consolidated Balance Sheets as of May 30, 2015, the Consolidated Statement of Stockholders’ Equity as of May 31, 2014, Note 13 - Warranties, Guarantees, and Contingencies, and Note 14 - Operating Segments. This correction had no impact on earnings or cash flows.

Business Combination Disclosure	Acquisitions and Divestitures George Nelson Bubble Lamp Product Line Acquisition On September 17, 2015, the company acquired certain assets associated with the George Nelson Bubble Lamp product line which together constituted the acquisition of a business. Consideration transferred to acquire the assets consisted of $3.6 million in cash transferred during the second quarter of fiscal 2016 and an additional component of performance-based contingent consideration with a fair value of $2.7 million as of the acquisition date. The assets acquired included an exclusive manufacturing agreement and customer relationships with fair values of $2.5 million and $0.6 million , respectively, each having a useful life of 10 years . The excess of the purchase consideration over the fair value of the net assets acquired was $3.2 million and recognized as goodwill within the Consumer reportable segment. The total amount of this goodwill is deductible for tax purposes and the impact on net sales and net earnings during the fiscal year was nominal. The company has finalized the purchase accounting for the acquisition of the George Nelson Bubble Lamp product line. Design Within Reach Acquisition On July 28, 2014, the company acquired the majority of the outstanding equity of Design Within Reach, Inc. ("DWR"), a Stamford, Connecticut based, leading North American marketer and seller of modern furniture, lighting, and accessories primarily serving consumers and design trade professionals. The acquisition of DWR advances the company's strategy of being both an industry brand and a consumer brand by expanding the company's reach into the consumer sector. The company purchased an ownership interest in DWR equal to approximately 81 percent for $155.2 million in cash. Subsequent to the initial transaction, the company acquired an additional 4 percent of DWR stock from the remaining public shareholders for approximately $5.8 million in cash, all of which was paid during the first and second quarters of fiscal 2015. The remaining 15 percent of DWR stock was contributed by DWR executives into the newly formed consumer business subsidiary and the company contributed the assets of the existing Herman Miller Consumer business. After these transactions, the redeemable noncontrolling interests in the newly formed subsidiary, known as Herman Miller Consumer Holdings, Inc. ("HMCH"), were approximately 7 percent . The remaining HMCH shareholders have a put option to require the company to purchase their remaining interest over a five years period from the date of issuance of such shares. As a result, these noncontrolling interests are not included within Stockholders' Equity within the Condensed Consolidated Balance Sheets, but rather are included within Redeemable noncontrolling interests. DWR acquisition-related expenses were $2.2 million during fiscal year 2015. These expenses included legal and professional services fees.

This debt was paid through the use of borrowings on the company’s revolving line of credit. During the first quarter of fiscal 2015, the company entered into a third amendment and restatement of its syndicated revolving line of credit, which provides the company with up to $250 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 $125 million . The facility expires in July 2019 and 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 May 28, 2016, the total debt outstanding related to borrowings against this facility was $22.0 million . Of the borrowings against this facility, $18.0 million has an interest rate of 1.28 percent and the remaining $4.0 million has an interest rate of 1.29 percent .

Our senior notes and the unsecured senior revolving credit facility restrict, without prior consent, our borrowings, capital leases, and the sale of certain assets. In addition, we have agreed to maintain certain financial performance ratios, which include a maximum leverage ratio covenant, which is measured by the ratio of debt to trailing four quarter adjusted EBITDA (as defined in the credit agreement) and is required to be less than 3.5 :1, except that we may elect, under certain conditions, to increase the maximum Leverage Ratio to 4 :1 for four consecutive fiscal quarter end dates. The covenants also require a minimum interest coverage ratio, which is measured by the ratio of trailing four quarter EBITDA to trailing four quarter interest expense (as defined in the credit agreement) and is required to be greater than 4 :1. Adjusted EBITDA is generally defined in the credit agreement as EBITDA adjusted by certain items which include non-cash share-based compensation, non-recurring restructuring costs, legacy pension expenses and extraordinary ite ms.

Compensation and Retirement Disclosure [Abstract]
Compensation and Employee Benefit Plans	Employee Benefit Plans The company maintains retirement benefit plans for substantially all of its employees. Pension Plans and Post-Retirement Medical Insurance The company offers certain employees retirement benefits under domestic defined benefit p lans. The company provides healthcare benefits to employees who retired from service on or before a qualifying date in 1998. As of the qualifying date, the company discontinued offering post-retirement medical to future retirees. Benefits to qualifying retirees under this plan are based on the employee's years of service and age at the date of retirement. In addition to the domestic pension and retiree healthcare plan, one of the company's wholly owned foreign subsidiaries has a defined-benefit pension plan based upon an average final pay benefit calculation. The measurement date for the company's principal domestic and international pension plans, as well as its post-retirement medical plan, is the last day of the fiscal year. During fiscal 2014, the company settled the remaining obligations associated with its primary domestic defined benefit pension plans. Plan participants received vested benefits from the plan assets by electing either a lump sum distribution, roll-over contribution to other 401(k) or individual retirement plans, or an annuity contract with a qualifying third-party provider. As a result of the settlement, the company was relieved of any further obligation. Pension settlement charges of $158.2 million , before tax, were recorded during fiscal year 2014. The settlement expenses included the pre-tax reclassifications of actuarial gains and losses from accumulated other comprehensive loss of $137.7 million , and cash contributions to the plan of $48.8 million , net of the outstanding pension plan liability prior to settlement. Cost of goods sold included $49.3 million of the settlement expense, while $108.9 million of the expense was included in operating expenses. After the settlement, the remaining pension assets of $0.9 million were transferred to the company's defined contribution 401(k) plan. The primary domestic defined-benefit plan included benefits determined by a cash balance calculation. Benefits under this plan were based upon an employee's years of service and earnings. Benefit Obligations and Funded Status The following table presents, for the fiscal years noted, a summary of the changes in the projected benefit obligation, plan assets and funded status of the company's domestic and international pension plans and post-retirement plan: Pension Benefits Post-Retirement Benefits 2016 2015 2016 2015 (In millions) Domestic International Domestic International Change in benefit obligation: Benefit obligation at beginning of year $ 1.1 $ 112.0 $ 1.1 $ 105.4 $ 7.7 $ 7.5 Interest cost — 3.8 — 4.3 0.2 0.2 Foreign exchange impact — (4.6 ) — (9.8 ) — — Actuarial (gain)/loss — (4.4 ) — 15.0 (1.3 ) 0.8 Benefits paid (0.1 ) (2.4 ) — (2.9 ) (0.7 ) (0.8 ) Benefit obligation at end of year $ 1.0 $ 104.4 $ 1.1 $ 112.0 $ 5.9 $ 7.7 Change in plan assets: Fair value of plan assets at beginning of year $ — $ 92.0 $ — $ 94.8 $ — $ — Actual return on plan assets — (1.3 ) — 8.0 — — Foreign exchange impact — (3.7 ) — (8.5 ) — — Employer contributions 0.1 0.4 — 0.6 0.7 0.8 Benefits paid (0.1 ) (2.4 ) — (2.9 ) (0.7 ) (0.8 ) Fair value of plan assets at end of year $ — $ 85.0 $ — $ 92.0 $ — $ — Funded status: Under funded status at end of year $ (1.0 ) $ (19.4 ) $ (1.1 ) $ (20.0 ) $ (5.9 ) $ (7.7 ) Components of the amounts recognized in the Consolidated Balance Sheets: Current liabilities $ (0.1 ) $ — $ (0.1 ) $ — $ (0.7 ) $ (0.9 ) Non-current liabilities $ (0.9 ) $ (19.4 ) $ (1.0 ) $ (20.0 ) $ (5.2 ) $ (6.8 ) Components of the amounts recognized in accumulated other comprehensive loss before the effect of income taxes: Unrecognized net actuarial loss (gain) $ 0.3 $ 39.3 $ 0.3 $ 41.6 $ (0.2 ) $ 1.1 Unrecognized prior service cost (credit) — — — — — — Accumulated other comprehensive loss $ 0.3 $ 39.3 $ 0.3 $ 41.6 $ (0.2 ) $ 1.1 The accumulated benefit obligation for the company's domestic pension benefit plans tota led $1.0 million as of the end of fiscal 2016 and $1.1 million as of the end of fiscal 2015 .

Actuarial Assumptions The weighted-average actuarial assumptions used to determine the benefit obligation amounts and the net periodic benefit cost for the company's pension and post-retirement plans are as follows: The weighted-average used in the determination of net periodic benefit cost: 2016 2015 2014 (Percentages) Domestic International Domestic International Domestic International Discount rate 3.41 3.50 3.44 4.40 3.43 4.40 Compensation increase rate n/a 3.20 n/a 3.35 n/a 3.50 Expected return on plan assets n/a 6.10 n/a 6.10 n/a 6.00 The weighted-average used in the determination of the projected benefit obligations: Discount rate 3.51 3.43 3.41 3.50 3.44 4.40 Compensation increase rate n/a 2.95 n/a 3.20 n/a 3.35 Effective May 28, 2016, the company changed the method it uses to estimate the interest component of net periodic benefit cost for pension and other postretirement benefits. Historically, the company has estimated the interest cost component utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. The company has elected to utilize a full yield curve approach in the estimation of interest cost by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. The company has made this change to provide a more precise measurement of interest cost by improving the correlation between projected benefit cash flows to the corresponding spot yield curve rates. The company accounted for this change as a change in accounting estimate and accordingly will account for it prospectively. The company estimates the impact of this change on the consolidated earnings for fiscal 2017 will be a reduction of the interest cost component of net periodic benefit cost of approximately $0.4 million . For fiscal 2016, the use of the full yield curve approach did not impact how the company measured the total benefit obligations at year end or the annual net periodic benefit cost as any change in the interest cost component is completely offset by the actuarial gain or loss measured at year end, which is immediately recognized in the income statement. Accordingly, this change in estimate did not impact the Consolidated Statement of Comprehensive Income for the fiscal year ended May 28, 2016. In calculating post-retirement benefit obligations for fiscal 2016 , a 7.9 percent annual rate of increase in the per capita cost of covered healthcare benefits was assumed for 2016, decreasing gradually to 4.3 percent by 2038 and remaining at that level thereafter. For purposes of calculating post-retirement benefit costs, a 7.1 percent annual rate of increase in the per capita cost of covered healthcare benefits was assumed for 2016 , decreasing gradually to 4.5 percent by 2029 an d remaining at that level thereafter. Assumed health care cost-trend rates have a significant effect on the amounts reported for retiree health care costs. A one-percentage-point change in the assumed health care cost-trend rates would have the following effects: (In millions) 1 Percent Increase 1 Percent Decrease Effect on total fiscal 2016 service and interest cost components $ — $ — Effect on post-retirement benefit obligation at May 28, 2016 $ 0.2 $ (0.2 ) Plan Assets and Investment Strategies The assets related to the company's primary domestic employee benefit plans were liquidated in connection with the plan termination that occurred during fiscal 2014. Accordingly, plan assets for the primary domestic employee benefit plans were zero as of the end of fiscal 2014. The company's international employee benefit plan assets consist mainly of listed fixed income obligations and common/collective trusts. The company's primary objective for invested pension plan assets is to provide for sufficient long-term growth and liquidity to satisfy all of its benefit obligations over time. Accordingly, the company has developed an investment strategy that it believes maximizes the probability of meeting this overall objective. This strategy includes the development of a target investment allocation by asset category in order to provide guidelines for making investment decisions. This target allocation emphasizes the long-term characteristics of individual asset classes as well as the diversification among multiple asset classes. In developing its strategy, the company considered the need to balance the varying risks associated with each asset class with the long-term nature of its benefit obligations. The company's strategy moving forward will be to increase the level of fixed income investments as the funding status improves, thereby more closely matching the return on assets with the liabilities of the plans. The company utilizes independent investment managers to assist with investment decisions within the overall guidelines of the investment strategy. The target asset allocation at the end of fiscal 2016 and asset categories for the company's primary international pension plan for fiscal 2016 and 2015 is as follows: Asset Category Targeted Asset Allocation Percentage Percentage of Plan Assets at Year End 2016 2015 Equities — — 2 Fixed Income 20 24 23 Common collective trusts 80 76 75 Total 100 100 (In millions) International Plan as of May 31, 2016 Asset Category Level 1 Level 2 Total Cash and cash equivalents $ 0.2 $ — $ 0.2 Foreign government obligations — 20.5 20.5 Common collective trusts-balanced — 64.3 64.3 Total $ 0.2 $ 84.8 $ 85.0 (In millions) International Plan as of May 31, 2015 Asset Category Level 1 Level 2 Total Cash and cash equivalents $ 1.8 $ 1.8 Foreign government obligations — 21.3 21.3 Common collective trusts-balanced 68.9 68.9 Total $ 1.8 $ 90.2 $ 92.0 Cash Flows The company is reviewing whether any additional voluntary pension plan contributions will be made in the next year. Actual contributions will be dependent upon investment returns, changes in pension obligations, and other economic and regulatory factors. During fiscal 2016, the company made total cash contributions of $1.2 million to its benefit plans. In fiscal 2015 , the company made total cash contributions of $1.4 million to its benefit plans. The following represents a summary of the benefits expected to be paid by the plans in future fiscal years. These expected benefits were estimated based on the same actuarial valuation assumptions used to determine benefit obligations at May 28, 2016 . (In millions) Pension Benefits Domestic Pension Benefits International Post-Retirement Benefits 2017 $ 0.1 $ 2.5 $ 0.7 2018 $ 0.1 $ 2.8 $ 0.7 2019 $ 0.1 $ 2.6 $ 0.7 2020 $ 0.1 $ 2.8 $ 0.6 2021 $ 0.1 $ 3.5 $ 0.6 2022-2026 $ 0.3 $ 18.7 $ 2.1 Profit Sharing, 401(k) Plan, and Core Contribution Substantially all of the company’s domestic employees are eligible to participate in a defined contribution retirement plan, primarily the Herman Miller, Inc. profit sharing and 401(k) plan. Employees under the Herman Miller, Inc. profit sharing plan are eligible to begin participating on their date of hire. The Profit Sharing plan provides for discretionary contributions for eligible participants, payable in the company's common stock, of not more than 6 percent of employees' wages based on the company's financial performance. Under the Herman Miller, Inc. 401(k) plan the company matches 100 percent of employee contributions to their 401(k) accounts up to 3 percent of their pay. A core contribution of 4 percent is also included for most participants of the plan. The company’s other defined contribution retirement plans may provide for matching contributions, non-elective contributions and discretionary contributions as declared by management. The cost of the Herman Miller, Inc. profit sharing contribution during fiscal 2016 , 2015 , and 2014 was $10.9 million , $4.8 million and $6.4 million , respectively. The expense recorded for the company's 401(k) matching contributions and core contributions was approximately $21.9 million , $20.8 million , and $20.3 million in fiscal years 2016 , 2015 and 2014 , respectively.

The company has certain share-based payment awards that meet the definition of participating securities. The company has evaluated the impact of all participating securities under the two-class method, noting there was no impact on EPS. Common Stock The company has a share repurchase plan authorized by the Board of Directors on September 28, 2007, which provided share repurchase authorization of $300.0 million with no specified expiration date. During fiscal year 2016, 2015, and 2014, shares repurchased and retired totaled 482,040 , 121,488 and 408,391 shares respectively.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments	Stock-Based Compensation The company utilizes equity-based compensation incentives as a component of its employee and non-employee director and officer compensation philosophy. Currently, these incentives consist principally of stock options, restricted stock, restricted stock units and performance share units. The company also offers a stock purchase plan for its domestic and certain international employees. The company issues shares in connection with its share-based compensation plans from authorized, but unissued, shares. At May 28, 2016 there were 3,991,307 shares authorized under the various stock-based compensation plans. Valuation and Expense Information The company measures the cost of employee services received in exchange for an award of equity instruments based on their grant-date fair market value. This cost is recognized over the requisite service period. 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. The company classifies pre-tax stock-based compensation expense primarily within “Operating expenses” in the Consolidated Statements of Comprehensive Income. Pre-tax compensation expense and the related income tax benefit for all types of stock-based programs was as follows for the periods indicated: (In millions) May 28, 2016 May 30, 2015 May 31, 2014 Employee stock purchase program $ 0.3 $ 0.3 $ 0.3 Stock option plans 1.9 2.6 2.3 Restricted stock grants — 0.1 0.2 Restricted stock units 3.2 3.7 5.2 Performance share units 6.5 3.3 3.0 Total $ 11.9 $ 10.0 $ 11.0 Tax benefit $ 4.3 $ 3.6 $ 4.0 As of May 28, 2016 , total pre-tax stock-based compensation cost not yet recognized related to non-vested awards was approximately $9.7 million . The weighted-average period over which this amount is expected to be recognized is 1.35 years. The company estimated the fair value of employee stock options on the date of grant using the Black-Scholes model. In determining these values, the following weighted-average assumptions were used for the options granted during the fiscal years indicated. 2016 2015 2014 Risk-free interest rates (1) 1.51 % 1.46 % 1.62 % Expected term of options (2) 4.0 years 4.0 years 5.5 years Expected volatility (3) 33 % 36 % 46 % Dividend yield (4) 2.03 % 1.85 % 1.74 % Weighted-average grant-date fair value of stock options: Granted with exercise prices equal to the fair market value of the stock on the date of grant 6.73 7.74 10.68 (1) Represents the U.S. Treasury yield over the same period as the expected option term. (2) Represents the period of time that options granted are expected to be outstanding. Based on analysis of historical option exercise activity, the company has determined that all employee groups exhibit similar exercise and post-vesting termination behavior. (3) Amount is determined based on analysis of historical price volatility of the company's common stock over a period equal to the expected term of the options. (4) Represents the company's estimated cash dividend yield over the expected term of options. Stock-based compensation expense recognized in the Consolidated Statements of Comprehensive Income, has been reduced for estimated forfeitures, as it is based on awards ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on historical experience. Employee Stock Purchase Program Under the terms of the company's Employee Stock Purchase Plan, 4 million shares of authorized common stock were reserved for purchase by plan participants at 85 percent of the market price. Shares of common stock purchased under the employee stock purchase plan were 70,768 , 62,467 and 63,753 for the fiscal years ended 2016, 2015 and 2014 respectively. Stock Option Plans The company has stock option plans under which options to purchase the company's stock are granted to employees and non-employee directors at a price not less than the market price of the company's common stock on the date of grant. Under the current award program, all options become exercisable between one and three years from date of grant and expire ten years from date of grant. Most options are subject to graded vesting with the related compensation expense recognized on a straight-line basis over the requisite service period. The following is a summary of the transactions under the company's stock option plans: Shares Under Option Weighted-Average Exercise Prices Weighted-Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (In millions) Outstanding at May 30, 2015 1,302,623 $ 26.05 4.0 $ 4.7 Granted at market 91,070 $ 29.03 Exercised (288,470 ) $ 23.15 Forfeited or expired (183,843 ) $ 33.33 Outstanding at May 28, 2016 921,380 $ 25.80 4.2 5.5 Ending vested + expected to vest 921,380 $ 25.80 4.2 $ 5.5 Exercisable at end of period 764,060 $ 25.06 3.3 $ 5.1 The total pre-tax intrinsic value of options exercised during fiscal 2016 , 2015 and 2014 was $2.3 million , $2.4 million , and $6.2 million , respectively. The aggregate intrinsic value in the preceding table represents the total pre-tax intrinsic value, based on the company's closing stock price as of the end of the period presented, which would have been received by the option holders had all option holders exercised in-the-money options as of that date. Total cash received during fiscal 2016 from the exercise of stock options was $5.0 million . Restricted Stock Grants The company periodically grants restricted common stock to certain key employees. Shares are granted in the name of the employee, who has all the rights of a shareholder, subject to certain restrictions on transferability and risk of forfeiture. The grants are subject to either cliff-based or graded vesting over a period not exceeding five years , and are subject to forfeiture if the employee ceases to be employed by the company for certain reasons. After the vesting period, the risk of forfeiture and restrictions on transferability lapse. The company recognizes the related compensation expense on a straight-line basis over the requisite service period. A summary of shares subject to restrictions are as follows: 2016 Shares Weighted Average Grant-Date Fair Value Outstanding at May 30, 2015 50,323 $ 20.80 Granted — $ — Vested (28,500 ) $ 20.37 Forfeited (1,000 ) $ 21.71 Outstanding at May 28, 2016 20,823 $ 21.35 The weighted-average remaining recognition period of the outstanding restricted stock grants at May 28, 2016 , was 0.55 years. The fair value of the shares that vested during the twelve months ended May 28, 2016 , was $0.8 million . There were no restricted stock grants granted during fiscal 2016, 2015 or 2014. Restricted Stock Units The company grants restricted stock units to certain key employees. This program provides that the actual number of restricted stock units awarded is based on the value of a portion of the participant's long-term incentive compensation divided by the fair value of the company's stock on the date of grant. In some years the awards have been partially tied to the company's financial performance for the year in which the grant was based. The awards generally cliff-vest after a three -year service period, with prorated vesting under certain circumstances and full or partial accelerated vesting upon retirement. Each restricted stock unit represents one equivalent share of the company's common stock to be awarded, free of restrictions, after the vesting period. Compensation expense related to these awards is recognized over the requisite service period, which includes any applicable performance period. Dividend equivalent awards are credited quarterly. The units do not entitle participants to the rights of stockholders of common stock, such as voting rights, until shares are issued after vesting. The following is a summary of restricted stock unit transactions for the fiscal years indicated: Share Units Weighted Average Grant-Date Fair Value Aggregate Intrinsic Value in Millions Weighted-Average Remaining Contractual Term (Years) Outstanding at May 30, 2015 505,472 $ 24.21 $ 13.5 1.2 Granted 110,176 $ 29.03 Forfeited (17,321 ) $ 27.09 Released (220,466 ) $ 19.97 Outstanding at May 28, 2016 377,861 $ 27.83 $ 12.0 1.4 Ending vested + expected to vest 377,861 27.83 $ 10.8 1.4 The weighted-average remaining recognition period of the outstanding restricted stock units at May 28, 2016 , was 1.09 years. The fair value of the share units that vested during the twelve months ended May 28, 2016 , was $6.4 million . The weighted average grant-date fair value of restricted stock units granted during 2016, 2015, and 2014 was $29.03 , $30.38 , and $28.55 respectively. Performance Share Units The company grants performance share units to certain key employees. The number of units initially awarded was based on the value of a portion of the participant's long-term incentive compensation, divided by the fair value of the company's common stock on the date of grant. Each unit represents one equivalent share of the company's common stock. The number of common shares ultimately issued in connection with these performance share units is determined based on the company's financial performance over the related three -year service period or the company's financial performance based on certain total shareholder return results as compared to a selected group of peer companies. Compensation expense is determined based on the grant-date fair value and the number of common shares projected to be issued, and is recognized over the requisite service period. The following is a summary of performance share unit transactions for the fiscal years indicated: Share Units Weighted Average Grant-Date Fair Value Aggregate Intrinsic Value in Millions Weighted-Average Remaining Contractual Term (Years) Outstanding at May 30, 2015 356,906 $ 29.17 $ 9.9 1.3 Granted 154,621 $ 30.81 Forfeited (21,988 ) $ 20.64 Released (55,825 ) $ 17.10 Outstanding at May 28, 2016 433,714 $ 31.74 $ 13.7 1.2 Ending vested + expected to vest 433,714 $ 31.74 $ 13.7 1.2 The weighted-average remaining recognition period of the outstanding performance share units at May 28, 2016 , was 0.8 years. The fair value for shares that vested during the twelve months ended May 28, 2016 , was $1.6 million . The weighted average grant-date fair value of performance share units granted during 2016, 2015, and 2014 was $30.81 , $32.71 , and $31.66 respectively. Herman Miller Consumer Holding Stock (HMCH) Option Plan Certain employees were granted options to purchase stock of HMCH at a price not less than the market price of HMCH common stock on the date of grant. For the grants of options under the award program, options are potentially exercisable between one year and five years from date of grant and expire at the end of the window period that follows the fifth anniversary of the grant date. Vesting is based on the performance of HMCH over a period of five years . These options have been classified as liability awards as the holders have the right to put the underlying shares to the company immediately upon exercise. Given this, the awards are measured at fair value at the end of each reporting period and compensation expense is adjusted accordingly to reflect the fair value over the requisite service period. The company estimates the issuance date fair value of HMCH stock options on the date of grant using the Black-Scholes model. The expense for these awards was a benefit of $0.3 million during fiscal 2016 and the related liability for these awards was $0.8 million as of the end of fiscal 2016. The liability for the HMCH stock options is recorded within the Consolidated Balance Sheets within the "Other liabilities" line item. The following weighted-average assumptions were used to value the liability associated with HMCH stock options as of May 28, 2016 and May 30, 2015. 2016 2015 Risk-free interest rates (1) 1.07 % 0.99 % Expected term of options (2) 3.1 years 3.2 years Expected volatility (3) 35 % 35 % Dividend yield not applicable not applicable Strike price $ 24.39 24.39 Per share value (4) $ 6.52 8.71 (1) Represents the U.S. Treasury yield over the same period as the expected option term. (2) Represents the period of time that options granted are expected to be outstanding. (3) Amount is determined based on analysis of historical price volatility of the common stock of peer companies over a period equal to the expected term of the options. (4) Based on the Black-Scholes formula. Shares Under Option Weighted-Average Exercise Prices Weighted-Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (In millions) Outstanding at May 30, 2015 504,669 $ 23.92 4.2 $ 2.1 Granted — $ — Exercised (4,293 ) $ 6.12 Forfeited — $ — Outstanding at May 28, 2016 500,376 $ 24.07 3.2 $ 0.4 Exercisable at end of period 9,290 $ 7.10 3.2 0.2 The total pre-tax intrinsic value of HMCH options exercised during fiscal 2016 was $0.1 million . The aggregate intrinsic value in the preceding table represents the total pre-tax intrinsic value, based on the HMCH market price, less the strike price, as of the end of the period presented, which would have been received by the option holders had all option holders exercised in-the-money options as of that date. Deferred Compensation Plan The Herman Miller, Inc. Executive Equalization Retirement Plan is a supplemental deferred compensation plan and was made available for salary deferrals and company contributions beginning in January 2008. The plan is available to a select group of management or highly compensated employees who are selected for participation by the Executive Compensation Committee of the Board of Directors. The plan allows participants to defer up to 50 percent of their base salary and up to 100 percent of their incentive cash bonus. Company contributions to the plan “mirror” the amounts the company would have contributed to the various qualified retirement plans had the employee's compensation not been above the IRS statutory ceiling ( $265,000 in 2016 ). The company does not guarantee a rate of return for these funds. Instead, participants make investment elections for their deferrals and company contributions. Investment options are the same as those available under the Herman Miller Profit Sharing and 401(k) Plan, except for company stock, which is not an investment option under this plan. In accordance with the terms of the Executive Equalization Plan, the salary and bonus deferrals and company contributions have been placed in a Rabbi trust. The assets in the Rabbi trust remain subject to the claims of creditors of the company and are not the property of the participant and are, therefore, included as an asset on the company's Consolidated Balance Sheets within the "Other assets" line item. A liability of the same amount is recorded on the Consolidated Balance Sheets within the "Other liabilities" line item. Investment assets are classified as trading, and accordingly, realized and unrealized gains and losses are recognized within the company's Consolidated Statements of Comprehensive Income in the interest and other investment income line item. The associated changes to the liability are recorded as compensation expense within the "Selling, general and administrative" line item within the company's Consolidated Statements of Comprehensive Income. The net effect of any change to the asset and corresponding liability is offset and has no impact on the Consolidated Statements of Comprehensive Income. Director Fees Company directors may elect to receive their director fees in one or more of the following forms: cash, deferred compensation in the form of shares or other selected investment funds, unrestricted company stock at the market value at the date of election, or stock options that vest in one year and expire in ten years . The exercise price of the stock options granted may not be less than the market price of the company's common stock on the date of grant. Under the plan, the Board members received the following shares or options in the fiscal years indicated: 2016 2015 2014 Shares of common stock 21,988 13,752 12,358 Shares through the deferred compensation program 3,118 — 2,317

Income Tax Disclosure	Income Taxes The components of earnings (loss) before income taxes are as follows: (In millions) 2016 2015 2014 Domestic $ 154.9 $ 142.5 $ (45.1 ) Foreign 41.7 2.7 1.7 Total $ 196.6 $ 145.2 $ (43.4 ) The provision (benefit) for income taxes consists of the following: (In millions) 2016 2015 2014 Current: Domestic - Federal $ 36.4 $ 43.6 $ 22.2 Domestic - State 6.4 6.3 4.6 Foreign 6.3 6.1 4.8 49.1 56.0 31.6 Deferred: Domestic - Federal 7.5 (5.9 ) (43.6 ) Domestic - State 0.2 (0.6 ) (5.6 ) Foreign 2.7 (2.3 ) (3.6 ) 10.4 (8.8 ) (52.8 ) Total income tax provision $ 59.5 $ 47.2 $ (21.2 ) The following table represents a reconciliation of income taxes at the United States statutory rate with the effective tax rate as follows: (In millions) 2016 2015 2014 Income taxes computed at the United States Statutory rate of 35% $ 68.8 $ 50.8 $ (15.2 ) Increase (decrease) in taxes resulting from: Change in unrecognized tax benefits 0.2 — 0.4 Foreign statutory rate differences (4.3 ) (1.0 ) (0.9 ) Manufacturing deduction under the American Jobs Creation Act of 2004 (4.8 ) (4.8 ) (3.9 ) State taxes 5.2 4.2 (0.9 ) Tax on undistributed foreign earnings — (3.9 ) — Sale of manufacturing facility in the United Kingdom (1.6 ) — — Other, net (4.0 ) 1.9 (0.7 ) Income tax expense (benefit) $ 59.5 $ 47.2 $ (21.2 ) Effective tax rate 30.3 % 32.6 % 48.9 % The tax effects and types of temporary differences that give rise to significant components of the deferred tax assets and liabilities at May 28, 2016 and May 30, 2015 , are as follows: (In millions) 2016 2015 Deferred tax assets: Compensation-related accruals $ 23.2 $ 21.9 Accrued pension and post-retirement benefit obligations 9.2 11.0 Deferred revenue 5.6 2.9 Inventory related 3.8 6.4 Reserves for uncollectible accounts and notes receivable 1.2 1.4 Other reserves and accruals 3.0 3.6 Warranty 15.7 14.0 State and local tax net operating loss carryforwards and credits 5.7 5.7 Federal net operating loss carryforward 7.1 12.2 Foreign tax net operating loss carryforwards and credits 14.6 10.0 Undistributed foreign earnings — 4.5 Other 4.7 4.4 Subtotal 93.8 98.0 Valuation allowance (10.6 ) (11.1 ) Total $ 83.2 $ 86.9 Deferred tax liabilities: Book basis in property in excess of tax basis $ (24.8 ) $ (16.7 ) Intangible assets (47.4 ) (44.5 ) Other (2.2 ) (3.6 ) Total $ (74.4 ) $ (64.8 ) The future tax benefits of net operating loss (NOL) carry-forwards and foreign tax credits are recognized to the extent that realization of these benefits is considered more likely than not. The company bases this determination on the expectation that related operations will be sufficiently profitable or various tax planning strategies will enable the company to utilize the NOL carry-forwards and/or foreign tax credits. To the extent that available evidence about the future raises doubt about the realization of these tax benefits, a valuation allowance is established. At May 28, 2016 , the company had state and local tax NOL carry-forwards of $70.9 million , the state tax benefit of which is $5.2 million , which have various expiration periods from one to twenty-one years. The company also had state credits with a state tax benefit of $0.5 million which expires in 4 to six years . For financial statement purposes, the NOL carry-forwards and state tax credits have been recognized as deferred tax assets, subject to a valuation allowance of $2.1 million . At May 28, 2016 , the company had federal NOL carry-forwards of $20.4 million , the tax benefit of which is $7.1 million , which expire in 12 to 13 years. For financial statement purposes, the NOL carry-forwards have been recognized as deferred tax assets. At May 28, 2016, the company had federal deferred assets of $1.5 million , the tax benefit of which is $0.5 million , which is related to investments in various foreign joint ventures. For financial statement purposes, the assets have been recognized as deferred tax assets, subject to a valuation allowance of $0.5 million . At May 28, 2016 , the company had foreign net operating loss carry-forwards of $49.2 million , the tax benefit of which is $10.9 million , which have expiration periods from seven years to an unlimited term. The company also had foreign tax credits with a tax benefit of $3.7 million which expire in one to eleven years. For financial statement purposes, NOL carry-forwards and foreign tax credits have been recognized as deferred tax assets, subject to a valuation allowance of $7.5 million . At May 28, 2016 , the company had foreign deferred assets of $2.7 million , the tax benefit of which is $0.5 million , which is related to various deferred taxes in Hong Kong and buildings in the United Kingdom. For financial statement purposes, the assets have been recognized as deferred tax assets, subject to a valuation allowance of $0.5 million . The company has not provided for United States income taxes on undistributed earnings of foreign subsidiaries totaling approximately $117.2 million . Recording deferred income taxes on these undistributed earnings is not required, because these earnings have been deemed to be indefinitely reinvested. These amounts would be subject to possible U.S. taxation only if remitted as dividends. The determination of the hypothetical amount of unrecognized deferred U.S. taxes on undistributed earnings of foreign entities is not practicable. The components of the company's unrecognized tax benefits are as follows: (In millions) Balance at May 31, 2014 $ 1.8 Increases related to current year income tax positions 0.4 Increases related to prior year income tax positions 0.1 Decreases related to prior year income tax positions (0.4 ) Decreases related to lapse of applicable statute of limitations (0.1 ) Decreases related to settlements — Balance at May 30, 2015 1.8 Increases related to current year income tax positions 0.4 Increases related to prior year income tax positions 0.1 Decreases related to prior year income tax positions (0.1 ) Decreases related to lapse of applicable statute of limitations (0.1 ) Decreases related to settlements (0.4 ) Balance at May 28, 2016 $ 1.7 The company's effective tax rate would have been affected by the total amount of unrecognized tax benefits had this amount been recognized as a reduction to income tax expense. The company recognizes interest and penalties related to unrecognized tax benefits through "Income tax expense (benefit)" in its Consolidated Statements of Comprehensive Income. Interest and penalties and the related liability, which are excluded from the table above, were as follows for the periods indicated: (In millions) May 28, 2016 May 30, 2015 May 31, 2014 Interest and penalty expense (income) $ (0.1 ) $ 0.4 $ 0.2 Liability for interest and penalties $ 0.7 $ 0.9 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 12 months as a result of new positions that may be taken on income tax returns, settlement of tax positions and the closing of statutes of limitation. It is not expected that any of the changes will be material to the company's Consolidated Statements of Comprehensive Income. During the year, the company has closed the audit of fiscal year 2015 with the Internal Revenue Service under the Compliance Assurance Process (CAP). For the majority of the remaining tax jurisdictions, the company is no longer subject to state and local, or non-U.S. income tax examinations by tax authorities for fiscal years before 2013.

Commitments Contingencies and Guarantees	Warranties, Guarantees, 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 . 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 beginning balances in the table below have been adjusted to reflect the immaterial error correction that is described in Note 1 to t he Consolidated Financial Statements. Changes in the warranty reserve for the stated periods were as follows: (In millions) 2016 2015 2014 Accrual balance, beginning $ 39.3 $ 37.7 $ 37.3 Accrual for warranty matters 25.5 25.0 20.2 Settlements (20.9 ) (23.4 ) (19.8 ) Accrual balance, ending $ 43.9 $ 39.3 $ 37.7 Other Guarantees The company is periodically required to provide performance bonds in order to conduct business with certain customers.

The North American Furniture Solutions reportable segment includes the operations associated with the design, manufacture, and sale of furniture products for work-related settings, including office, education, and healthcare environments, throughout the United States and Canada. ELA Furniture Solutions includes the operations associated with the design, manufacture, and sale of furniture products, primarily for work-related settings, in the EMEA, Latin America, and Asia-Pacific geographic regions. Specialty includes the operations associated with the design, manufacture, and sale of high-craft furniture products and textiles including Geiger wood products, Maharam textiles, and Herman Miller Collection products. The Consumer segment includes the operations associated with the sale of modern design furnishings and accessories to third party retail distributors, as well as direct to consumer sales through eCommerce and DWR studios. The company also reports a “Corporate” category consisting primarily of unallocated corporate expenses including restructuring, impairment, acquisition-related costs, and other unallocated corporate costs. The performance of the operating segments is evaluated by the company's management using various financial measures. The following is a summary of certain key financial measures for the respective fiscal years indicated: (In millions) 2016 2015 2014 Net Sales: North American Furniture Solutions $ 1,331.8 $ 1,241.9 $ 1,216.3 ELA Furniture Solutions 412.6 409.9 392.2 Specialty 231.8 219.9 205.8 Consumer 288.7 270.5 67.7 Corporate — — — Total $ 2,264.9 $ 2,142.2 $ 1,882.0 Depreciation and Amortization: North American Furniture Solutions $ 27.9 $ 26.5 $ 26.8 ELA Furniture Solutions 8.5 8.2 7.6 Specialty 7.4 7.4 6.8 Consumer 8.6 7.3 1.2 Corporate 0.6 0.4 — Total $ 53.0 $ 49.8 $ 42.4 Operating Earnings (Losses): North American Furniture Solutions $ 152.0 $ 125.2 $ (27.0 ) ELA Furniture Solutions 35.3 25.9 23.1 Specialty 16.4 13.5 (5.3 ) Consumer 8.1 14.7 9.9 Corporate (0.3 ) (15.9 ) (26.4 ) Total $ 211.5 $ 163.4 $ (25.7 ) Capital Expenditures: North American Furniture Solutions $ 56.8 $ 31.7 $ 28.9 ELA Furniture Solutions 15.0 20.3 6.4 Specialty 3.1 3.7 5.5 Consumer 10.2 7.9 — Corporate — — — Total $ 85.1 $ 63.6 $ 40.8 Total Assets: North American Furniture Solutions $ 531.7 $ 504.5 $ 461.5 ELA Furniture Solutions 218.4 235.4 244.8 Specialty 147.3 151.6 157.7 Consumer 245.3 231.8 18.8 Corporate 92.5 69.4 112.6 Total $ 1,235.2 $ 1,192.7 $ 995.4 Goodwill: North American Furniture Solutions $ 135.8 $ 135.8 $ 135.8 ELA Furniture Solutions 40.9 41.9 42.6 Specialty 49.8 49.8 49.8 Consumer 78.8 75.6 — Corporate — — — Total $ 305.3 $ 303.1 $ 228.2 The accounting policies of the reportable operating segments are the same as those of the company. Additionally, the company employs a methodology for allocating corporate costs and assets with the underlying objective of this methodology being to allocate corporate costs according to the relative usage of the underlying resources and to allocate corporate assets according to the relative expected benefit. The majority of the allocations for corporate expenses are based on relative net sales. However, certain corporate costs, generally considered the result of isolated business decisions, are not subject to allocation and are evaluated separately from the rest of the regular ongoing business operations. For example, restructuring and impairment expenses that are reflected in operating earnings are allocated to the “Corporate” category. In addition, cash and cash equivalents and marketable securities are allocated to the “Corporate” category as the company views these as corporate assets. The restructuring and asset impairment charges of $12.7 million and $26.5 million in fiscal 2015 and fiscal 2014, respectively, are discussed in Note 17 of the Consolidated Financial Statements and were allocated to the “Corporate” category. The company's product offerings consist primarily of office furniture systems, seating, freestanding furniture, storage and casegoods. These product offerings are marketed, distributed, and managed primarily as a group of similar products on an overall portfolio basis. The following is a summary of net sales estimated by product category for the respective fiscal years indicated.

Redeemable Noncontrolling Interests [Abstract]
Noncontrolling Interest Disclosure [Text Block]	16. Redeemable Noncontrolling Interests Redeemable noncontrolling interests are reported on the Consolidated Balance Sheets in mezzanine equity in “Redeemable noncontrolling interests.” The company recognizes changes to the redemption value of redeemable noncontrolling interests as they occur and adjusts the carrying value to equal the redemption value at the end of each reporting period accordingly. The redemption amounts have been estimated based on the fair value of the subsidiary, determined based on a weighting of the discounted cash flow and market methods. This represents a level 3 fair value measurement. Changes in the company’s Redeemable noncontrolling interests for the years ended May 28, 2016 and May 30, 2015 are as follows: Year Ended (In millions) May 28, 2016 May 30, 2015 Balance at beginning of period $ 30.4 $ — Increase due to business combinations — 25.7 Net income attributable to redeemable noncontrolling interests 0.5 0.5 Exercised options — 0.7 Redemption value adjustment (4.0 ) 3.3 Other adjustments 0.1 0.2 Balance at end of period $ 27.0 $ 30.4

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities Disclosure	Restructuring and Impairment Activities 2015 Restructuring and Impairment Charges The company recognized asset impairment expense totaling $10.8 million associated with the POSH trade name for the fiscal year 2015. Although profitability associated with the POSH trade name increased as compared to the prior year, forecasts developed during the fourth quarter of fiscal 2015 indicated that future revenue and profitability no longer supported the value of the trade name intangible asset. The company also recognized restructuring expenses of $1.9 million during the third quarter of fiscal 2015 related to targeted workforce reductions within the North American segment. These actions resulted in the recognition of restructuring expenses related to severance and outplacement costs. 2014 Restructuring and Impairment Charges The company recognized asset impairment expense totaling $21.4 million associated with the Nemschoff and POSH trade names for the fiscal year 2014. The company also recognized restructuring expense of $1.1 million during the third quarter of fiscal 2014. This restructuring was related to actions taken to improve the efficiency of the North American sales and distribution channel and Geiger manufacturing operations. These actions focused primarily on targeted workforce reductions. Due to the acquisition of a manufacturing and distribution operation in Dongguan, China in the second quarter of 2014, the company decided not to pursue the construction of a new manufacturing and distribution facility on property that it previously acquired in Ningbo, China. In connection with this decision, the company evaluated the fair value of this property and recorded an asset impairment of $4.0 million during the second quarter of fiscal 2014. This impairment charge was recorded to the "Restructuring and impairment expenses" line item within the Consolidated Statements of Comprehensive Income. The impairment charge is included within the "Corporate" category within the segment reporting. These charges have been reflected separately as "Restructuring and impairment expenses" in the Consolidated Statements of Comprehensive Income and are included in the "Corporate" category within the segment reporting within Note 14 .

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The Consolidated Financial Statements include the accounts of Herman Miller, Inc. and its majority-owned domestic and foreign subsidiaries. The consolidated entities are collectively referred to as “the company.” All intercompany accounts and transactions have been eliminated in the Consolidated Financial Statements. Nonconsolidated affiliates (20-50 percent owned companies) are accounted for using the equity method.
Fiscal Year	Fiscal Year The company's fiscal year ends on the Saturday closest to May 31. The fiscal years ended May 28, 2016 , May 30, 2015 , and May 31, 2014 each contain 52 weeks .
Foreign Currency Translation	Foreign Currency Translation The functional currency for most of the foreign subsidiaries is their local currency. The cumulative effects of translating the balance sheet accounts from the functional currency into the United States dollar using fiscal year-end exchange rates and translating revenue and expense accounts using average exchange rates for the period is reflected as a component of “Accumulated other comprehensive loss” in the Consolidated Balance Sheets. The financial statement impact of remeasuring all foreign currency transactions into the appropriate functional currency resulted in a net loss of $0.7 million , $2.1 million , and $1.2 million for the fiscal years ended May 28, 2016, May 30, 2015, and May 31, 2014, respectively. These amounts are included in “Other, net” in the Consolidated Statements of Comprehensive Income.
Cash Equivalents	Cash Equivalents The company holds cash equivalents as part of its cash management function. Cash equivalents include money market funds, time deposit investments, and treasury bills with original maturities of less than three months. The carrying value of cash equivalents, which approximates fair value, totaled $7.5 million an d $9.1 million as of May 28, 2016 and May 30, 2015 , respectively. All cash equivalents are high-credit quality financial instruments, and the amount of credit exposure to any one financial institution or instrument is limited.
Marketable Securities	Marketable Securities The company maintains a portfolio of marketable securities primarily comprised of mutual funds. These investments are held by the company's wholly owned insurance captive and are considered “available-for-sale” securities. Accordingly, they have been recorded at fair value based on quoted market prices, with the resulting net unrealized holding gains or losses reflected net of tax as a component of “Accumulated other comprehensive loss” in the Consolidated Balance Sheets. All marketable security transactions are recognized on the trade date. Realized gains and losses on disposal of available-for-sale investments are included in “Interest and other investment income” in the Consolidated Statements of Comprehensive Income. See Note 11 of the Consolidated Financial Statements for additional disclosures of marketable securities.
Accounts Receivable Allowances	Accounts Receivable Allowances Reserves for uncollectible accounts receivable balances are based on known customer exposures, historical credit experience, and the specific identification of other potentially uncollectible accounts. Balances are written off against the reserve once the company determines the probability of collection to be remote. The company generally does not require collateral or other security on trade accounts receivable.
Concentrations of Credit Risk	Concentrations of Credit Risk Our trade receivables are primarily due from independent dealers who, in turn, carry receivables from their customers. We monitor and manage the credit risk associated with individual dealers and direct customers where applicable. Dealers are responsible for assessing and assuming credit risk of their customers and may require their customers to provide deposits, letters of credit, or other credit enhancement measures. Some sales contracts are structured such that the customer payment or obligation is direct to us. In those cases, we may assume the credit risk. Whether from dealers or customers, our trade credit exposures are not concentrated with any particular entity.
Inventories	Inventories Inventories are valued at the lower of cost or market and include material, labor, and overhead. Inventory cost is determined using the last-in, first-out (LIFO) method at manufacturing facilities in Michigan, whereas inventories of the company's other locations are valued using the first-in, first-out (FIFO) method. The company establishes reserves for excess and obsolete inventory based on prevailing circumstances and judgment for consideration of current events, such as economic conditions, that may affect inventory. The reserve required to record inventory at lower of cost or market may be adjusted in response to changing conditions. Further information on the company's recorded inventory balances can be found in Note 3 of the Consolidated Financial Statements.
Property, Equipment, and Depreciation	Property, Equipment, and Depreciation Property and equipment are stated at cost. The cost is depreciated over the estimated useful lives of the assets using the straight-line method. Estimated useful lives range from 3 to 10 years for machinery and equipment and do not exceed 40 years for buildings. Leasehold improvements are depreciated over the lesser of the lease term or the useful life of the asset. We capitalize certain costs incurred in connection with the development, testing, and installation of software for internal use. Software for internal use is included in property and equipment and is depreciated over an estimated useful life not exceeding 5 years . Depreciation and amortization expense is included in the Consolidated Statements of Comprehensive Income in the "Cost of sales", "Selling, general and administrative", and "Design and research" line items.
Goodwill and Indefinite-Lived Intangible Assets	Goodwill and Indefinite-lived Intangible Assets 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. A reporting unit is defined as an operating segment or one level below an operating segment. 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 skip 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. To estimate the fair value of each reporting unit the company utilizes a weighting of the income method and the market method. The income method is based on a discounted future cash flow approach that uses a number of estimates, including revenue based on assumed growth rates, estimated costs, and discount rates based on the reporting unit's weighted average cost of capital. Growth rates for each reporting unit are estimated based on internal estimates, historical data, and external sources. The growth estimates are also used in planning for our long-term and short-term business planning and forecasting. We test the reasonableness of the inputs and outcomes of our discounted cash flow analysis against comparable market data. The market method is based on financial multiples of companies comparable to each reporting unit and applies a control premium. The carrying value of each reporting unit represents the assignment of various assets and liabilities, excluding corporate assets and liabilities, such as cash, investments, and debt. 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. The company utilizes the relief from royalty methodology to test for impairment. The primary assumptions for the relief from royalty method include revenue forecasts, royalty rates, and discount rates. The company measures and records an impairment loss for the excess of the carrying value of the asset over its fair value. The company's indefinite-lived intangible assets consist of certain trade names valued at approximately $85.2 million as of the end of both fiscal year 2016 and 2015 . These assets have indefinite useful lives. The company recognized asset impairment expense totaling $10.8 million associated with the POSH trade name for the fiscal year 2015, which was recorded within the "Corporate" category within segment reporting. The POSH trade name asset is included within the ELA Furniture Solutions segment and as of the end of fiscal 2015, the carrying value was zero. During the fiscal year 2014, the company recorded impairment expenses of $21.4 million associated with the Nemschoff and POSH trade names. These impairment expenses are recorded in the "Restructuring and impairment expenses" line item within the Consolidated Statements of Comprehensive Income and are included in the "Corporate" category within the segment reporting. The trade name assets represent level 3 fair value measurements and these assets are recorded at fair value only if an impairment charge is recognized.
Long-Lived Assets - Indefinite	Long-Lived Assets The company reviews other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or an asset group may not be recoverable. Each impairment test is based on a comparison of the carrying amount of the asset or asset group to the future undiscounted net cash flows expected to be generated by the asset or asset group, or in some cases, by prices for similar assets. If such assets are considered to be impaired, the impairment amount to be recognized is the amount by which the carrying value of the assets exceeds their fair value. Impairment expense of $4.0 million was recording during fiscal 2014 related to property in Ningbo, China. This was due to the acquisition of manufacturing-related assets, including a production facility and related equipment, in Dongguan, China, and as a result, the company decided not to pursue the construction of a new manufacturing and distribution facility on the previously acquired property in Ningbo. The company evaluated the fair value of this property and recorded an asset impairment equal to the excess of carrying value over fair value. This impairment charge was recorded in "Restructuring and impairment expenses", classified in the "Corporate" category for segment reporting purposes, and represents a level 3 fair value measurement. During the third quarter of fiscal 2015, the company entered into an agreement for the sale of the property in Ningbo, China, and subsequent to the end of fiscal 2015, the company completed the sale of the Ningbo property for cash consideration of approximately $4.2 million . Amortizable intangible assets within "Other amortizable intangibles, net" in the Consolidated Balance Sheets consist primarily of patents, trademarks, and customer relationships. The "customer relationships" intangible asset is comprised of relationships with customers and specifiers and networks and relationships with dealers and distributors. Refer to the following table for the combined gross carrying value and accumulated amortization for these amortizable intangibles.
Long-Lived Assets - Finite	Amortizable intangible assets within "Other amortizable intangibles, net" in the Consolidated Balance Sheets consist primarily of patents, trademarks, and customer relationships. The "customer relationships" intangible asset is comprised of relationships with customers and specifiers and networks and relationships with dealers and distributors. Refer to the following table for the combined gross carrying value and accumulated amortization for these amortizable intangibles. May 28, 2016 (In millions) Patent and Trademarks Customer Relationships Other Total Gross carrying value $ 19.8 $ 55.7 $ 7.5 $ 83.0 Accumulated amortization 12.3 15.9 4.0 32.2 Net $ 7.5 $ 39.8 $ 3.5 $ 50.8 May 30, 2015 Patent and Trademarks Customer Relationships Other Total Gross carrying value $ 18.8 $ 55.3 $ 5.0 $ 79.1 Accumulated amortization 11.7 12.0 3.1 26.8 Net $ 7.1 $ 43.3 $ 1.9 $ 52.3 The company amortizes these assets over their remaining useful lives using the straight-line method over periods ranging from 1.5 years to 20 years or on an accelerated basis to reflect the expected realization of the economic benefits. It is estimated that the weighted-average remaining useful life of patents and trademarks is approximately 5.5 years and the weighted-average remaining useful life of customer relationships is 10 years
Self Insurance	Self-Insurance The company is partially self-insured for general liability, workers' compensation, and certain employee health and dental benefits under insurance arrangements that provide for third-party coverage of claims exceeding the company's loss retention levels. The company's health benefit retention levels do not include an aggregate stop loss policy. The company's retention levels designated within significant insurance arrangements as of May 28, 2016 , ar e as follows: (In millions) Retention Level (per occurrence) General liability and auto liability/physical damage $ 1.00 Workers' compensation and property $ 0.75 The company accrues for its self-insurance arrangements based on actuarially-determined liabilities, which are recorded in “Other liabilities” in the Consolidated Balance Sheets. The value of the liability as of May 28, 2016 and May 30, 2015 was $10.6 million and $9.5 million , respectively. The actuarial valuations are based on historical information along with certain assumptions about future events. Changes in assumptions for such matters as legal actions, medical costs, and changes in actual experience could cause these estimates to change. The general and workers' compensation liabilities are managed through the company's wholly-owned insurance captive.
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interests Certain minority shareholders in the company's subsidiary Herman Miller Consumer Holdings, Inc. have the right, at specified times over a period of five years, to require the company to acquire portions of their ownership interest in those entities at fair value. Their interests in these subsidiaries are classified outside permanent equity in the Consolidated Balance Sheets and are carried at the current estimated redemption amounts. The redemption amounts have been estimated based on the fair value of the subsidiary, which was determined based on a weighting of the discounted cash flow and market methods. The discounted cash flow analysis used the present value of projected cash flows and a residual value. To determine the discount rate for the discounted cash flow method, a market-based approach was used to select the discount rates used. Market multiples for comparable companies were used for the market method of valuation. The fair value of the subsidiary is sensitive to changes in projected revenues and costs, the discount rate, and the forward multiples of the comparable companies. Changes in the estimated redemption amounts of the noncontrolling interests, subject to put options, are reflected at each reporting period with a corresponding adjustment to Retained earnings. Future reductions in the carrying amounts are subject to a “floor” amount that is equal to the fair value of the redeemable noncontrolling interests at the time they were originally recorded. See Note 16 - Redeemable Noncontrolling Interests for additional information. Changes in the company’s Redeemable noncontrolling interests for the years ended May 28, 2016 and May 30, 2015 are as follows: Year Ended (In millions) May 28, 2016 May 30, 2015 Balance at beginning of period $ 30.4 $ — Increase due to business combinations — 25.7 Net income attributable to redeemable noncontrolling interests 0.5 0.5 Exercised options — 0.7 Redemption value adjustment (4.0 ) 3.3 Other adjustments 0.1 0.2 Balance at end of period $ 27.0 $ 30.4
Research, Development, and Other Related Costs	Research, Development, and Other Related Costs Research, development, pre-production, and start-up costs are expensed as incurred. Research and development ("R&D") costs consist of expenditures incurred during the course of planned research and investigation aimed at discovery of new knowledge useful in developing new products or processes. R&D costs also include the significant enhancement of existing products or production processes and the implementation of such through design, testing of product alternatives, or construction of prototypes. R&D costs included in “Design and research” expense in the accompanying Consolidated Statements of Comprehensive Income are $62.4 million , $56.7 million , and $53.9 million , in fiscal 2016 , 2015 , and 2014 , respectively. Royalty payments made to designers of the company's products as the products are sold are a variable cost based on product sales. These expenses totaled $14.7 million , $14.7 million , and $12.0 million in fiscal years 2016 , 2015 , and 2014 respectively. They are included in "Design and research" expense in the accompanying Consolidated Statements of Comprehensive Income .
Customer Payments and Incentives	Customer Payments and Incentives We offer various sales incentive programs to our customers, such as rebates and discounts. Programs such as rebates and discounts are adjustments to the selling price and are therefore characterized as a reduction to net sales.
Revenue Recognition	Revenue Recognition The company recognizes revenue on sales through its network of independent contract furniture dealers and independent retailers once the related product is shipped and title passes. In situations where products are sold through subsidiary dealers or directly to the end customer, revenue is recognized once the related product is shipped to the end customer and installation, if applicable, is substantially complete. Offers such as rebates and discounts are recorded as reductions to net sales. Unearned revenue occurs during the normal course of business due to advance payments from customers for future delivery of products and services. In addition to independent retailers, the company also sells product through owned retail channels, including e-commerce and DWR retail studios. These sales may include provisions involving a right of return. The company reduces revenue for an estimate of potential future product returns related to current period product revenue. When developing the allowance for sales returns, the company considers historical returns and current economic trends.
Shipping and Handling Expenses	Shipping and Handling Expenses The company records shipping and handling related expenses under the caption “Cost of sales” in the Consolidated Statements of Comprehensive Income.
Cost of Sales	Cost of Sales We include material, labor, and overhead in cost of sales. Included within these categories are items such as freight charges, warehousing costs, internal transfer costs, and other costs of our distribution network.
Selling, General, and Administrative	Selling, General, and Administrative We include costs not directly related to the manufacturing of our products in the "Selling, general, and administrative" line item within the Consolidated Statements of Comprehensive Income. Included in these expenses are items such as compensation expense, rental expense, warranty expense, and travel and entertainment expense.
Income Taxes	Income Taxes Deferred tax assets and liabilities are recognized for the expected future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. The company's annual effective tax rate is based on income, statutory tax rates, and tax planning strategies available in the various jurisdictions the company operates. Complex tax laws can be subject to different interpretations by the company and the respective government authorities. Significant judgment is required in evaluating tax positions and determining our tax expense. Tax positions are reviewed quarterly and tax assets and liabilities are adjusted as new information becomes available. In evaluating the company's ability to recover deferred tax assets within the jurisdiction from which they arise, the company considers all positive and negative evidence. These assumptions require significant judgment about forecasts of future taxable income.
Stock-Based Compensation	Stock-Based Compensation The company has several stock-based compensation plans, which are described in Not e 9 of the Consolidated Financial Statements. Our policy is to expense stock-based compensation using the fair-value based method of accounting for all awards granted.
Earnings per Share	Earnings per Share Basic earnings per share (EPS) excludes the dilutive effect of common shares that could potentially be issued, due to the exercise of stock options or the vesting of restricted shares, and is computed by dividing net earnings by the weighted-average number of common shares outstanding for the period. Diluted EPS is computed by dividing net earnings by the sum of the weighted-averag e number of shares outstanding, plus all dilutive shares that could potentially be issued. The company also evaluates the impact on EPS of all participating securities under the two-class method. Refer to Note 8 of the Consolidated Financial Statements fo r further information regarding the computation of EPS.
Comprehensive Income	Comprehensive Income Comprehensive income consists of net earnings, foreign currency translation adjustments, unrealized holding gain (loss) on available-for-sale securities and pension liability adjustments. Refer to Note 15 of the Consolidated Financial Statements fo r further information regarding comprehensive income.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fair Value	Fair Value The company classifies and discloses its fair value measurements in one of the following three categories: • Level 1 — Financial instruments with unadjusted, quoted prices listed on active market exchanges. • Level 2 — Financial instruments lacking unadjusted, quoted prices from active market exchanges, including over-the-counter traded financial instruments. Financial instrument values are determined using prices for recently traded financial instruments with similar underlying terms and direct or indirect observational inputs, such as interest rates and yield curves at commonly quoted intervals. • Level 3 — Financial instruments not actively traded on a market exchange and there is little, if any, market activity. Values are determined using significant unobservable inputs or valuation techniques. See Note 11 of the Consolidated Financial Statements for the required fair value disclosures.
Foreign Currency Forward Contracts Not Designated as Hedges	Foreign Currency Forward Contracts Not Designated as Hedges The company transacts business in various foreign currencies and has established a program that primarily utilizes foreign currency forward contracts to offset 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. These foreign currency exposures typically arise from net liability or asset exposures in non-functional currencies on the balance sheets of our foreign subsidiaries. These 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 expenses (income): Other, net", for both realized and unrealized gains and losses.

Redeemable Noncontrolling Interests [Abstract]
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interests Certain minority shareholders in the company's subsidiary Herman Miller Consumer Holdings, Inc. have the right, at specified times over a period of five years, to require the company to acquire portions of their ownership interest in those entities at fair value. Their interests in these subsidiaries are classified outside permanent equity in the Consolidated Balance Sheets and are carried at the current estimated redemption amounts. The redemption amounts have been estimated based on the fair value of the subsidiary, which was determined based on a weighting of the discounted cash flow and market methods. The discounted cash flow analysis used the present value of projected cash flows and a residual value. To determine the discount rate for the discounted cash flow method, a market-based approach was used to select the discount rates used. Market multiples for comparable companies were used for the market method of valuation. The fair value of the subsidiary is sensitive to changes in projected revenues and costs, the discount rate, and the forward multiples of the comparable companies. Changes in the estimated redemption amounts of the noncontrolling interests, subject to put options, are reflected at each reporting period with a corresponding adjustment to Retained earnings. Future reductions in the carrying amounts are subject to a “floor” amount that is equal to the fair value of the redeemable noncontrolling interests at the time they were originally recorded. See Note 16 - Redeemable Noncontrolling Interests for additional information. Changes in the company’s Redeemable noncontrolling interests for the years ended May 28, 2016 and May 30, 2015 are as follows: Year Ended (In millions) May 28, 2016 May 30, 2015 Balance at beginning of period $ 30.4 $ — Increase due to business combinations — 25.7 Net income attributable to redeemable noncontrolling interests 0.5 0.5 Exercised options — 0.7 Redemption value adjustment (4.0 ) 3.3 Other adjustments 0.1 0.2 Balance at end of period $ 27.0 $ 30.4
