Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The consolidated financial statements include the accounts of Steelcase Inc. and its subsidiaries. We consolidate entities in which we maintain a controlling interest. All material intercompany transactions and balances have been eliminated in consolidation. We also consolidate variable interest entities when appropriate. Investments in entities where our equity ownership falls between 20% and 50% , or where we otherwise have significant influence, are accounted for under the equity method of accounting. All other investments in unconsolidated affiliates are accounted for under the cost method of accounting. These investments are reported as Investments in unconsolidated affiliates on the Consolidated Balance Sheets, and income from equity method and cost method investments are reported in Other income, net on the Consolidated Statements of Income . See Note 11 for additional information. Fiscal Year Our fiscal year ends on the last Friday in February, with each fiscal quarter typically including 13 weeks. The fiscal years ended February 23, 2018 , February 24, 2017 and February 26, 2016 contained 52 weeks. Reference to a year relates to the fiscal year, ended in February of the year indicated, rather than the calendar year, unless indicated by a specific date. Additionally, Q1, Q2, Q3 and Q4 reference the first, second, third and fourth quarter, respectively, of the fiscal year indicated. All amounts are in millions, except share and per share data, data presented as a percentage or as otherwise indicated. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the amounts and disclosures in the consolidated financial statements and accompanying notes. Although these estimates are based on historical data and management’s knowledge of current events and actions we may undertake in the future, actual results may differ from these estimates under different assumptions or conditions. Foreign Currency For most foreign operations, local currencies are considered the functional currencies. We translate assets and liabilities of these subsidiaries to their U.S. dollar equivalents at exchange rates in effect as of the balance sheet date. Translation adjustments are not included in determining net income but are recorded in Accumulated other comprehensive income (loss) on the Consolidated Balance Sheets unless and until a sale or a substantially complete liquidation of the net investment in the international subsidiary takes place. We translate Consolidated Statements of Income accounts at average exchange rates for the applicable period. Foreign currency transaction gains and losses, net of derivative impacts, arising primarily from changes in exchange rates on foreign currency denominated intercompany loans and other intercompany transactions and balances between foreign locations, are recorded in Other income, net on the Consolidated Statements of Income. Cash and Cash Equivalents Cash and cash equivalents include demand bank deposits and highly liquid investment securities with an original maturity of three months or less. Cash equivalents are reported at cost and approximate fair value. Outstanding checks in excess of funds on deposit are classified as Accounts payable on the Consolidated Balance Sheets. Our restricted cash balance as of February 23, 2018 and February 24, 2017 was $2.5 , and consisted of funds held in escrow for potential future workers’ compensation claims. Our restricted cash balance is classified in Other assets on the Consolidated Balance Sheets. Allowances for Credit Losses Allowances for credit losses related to accounts receivable and notes receivable are maintained at a level considered by management to be adequate to absorb an estimate of probable future losses existing at the balance sheet date. In estimating probable losses, we review accounts that are past due or in bankruptcy. We consider an accounts receivable or notes receivable balance past due when payment is not received within the stated terms. We review accounts that may have higher credit risk using information available about the debtor, such as financial statements, news reports and published credit ratings. We also use general information regarding industry trends, the economic environment and information gathered through our network of field-based employees. Using an estimate of current fair market value of any applicable collateral and other credit enhancements, such as third party guarantees, we arrive at an estimated loss for specific concerns and estimate an additional amount for the remainder of trade balances based on historical trends and other factors previously referenced. Receivable balances are written off when we determine the balance is uncollectible. Subsequent recoveries, if any, are credited to bad debt expense when received. Concentrations of Credit Risk Our trade receivables are due from independent dealers as well as direct customers. We monitor and manage the credit risk associated with individual dealers and direct customers. 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 typically assume the credit risk. Whether from dealers or direct customers, our trade credit exposures are not concentrated with any particular entity. Inventories Inventories are stated at the lower of cost or net realizable value. The Americas segment primarily uses the last in, first out (“LIFO”) method to value its inventories. The EMEA segment values inventories primarily using the first in, first out method. Businesses within the Other category primarily use the first in, first out or the average cost inventory valuation methods. See Note 7 for additional information. Property, Plant and Equipment Property, plant and equipment are stated at cost. Major improvements that materially extend the useful lives of the assets are capitalized. Expenditures for repairs and maintenance are charged to expense as incurred. Depreciation is provided using the straight-line method over the estimated useful lives of the assets. Long-lived assets such as property, plant and equipment are tested for impairment when conditions indicate that the carrying value may not be recoverable. We evaluate several conditions, including, but not limited to, the following: a significant decrease in the market price of an asset or an asset group; a significant adverse change in the extent or manner in which a long-lived asset is being used, including an extended period of idleness; and a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. We review the carrying value of our held and used long-lived assets utilizing estimates of future undiscounted cash flows. If the carrying value of a long-lived asset is considered impaired, an impairment charge is recorded for the amount by which the carrying value of the long-lived asset exceeds its estimated fair value. When assets are classified as “held for sale,” losses are recorded for the difference between the carrying amount of the property, plant and equipment and the estimated fair value less estimated selling costs. Assets are considered “held for sale” when it is expected that the asset is going to be sold within twelve months. Operating Leases Rent expense under operating leases is recorded on a straight-line basis over the lease term unless the lease contains an escalation clause which is not fixed and determinable. The lease term begins when we have the right to control the use of the leased property, which is typically before rent payments are due under the terms of the lease. If a lease has a fixed and determinable escalation clause, the difference between rent expense and rent paid is recorded as deferred rent. Rent expense under operating leases that do not have an escalation clause or where escalation is based on an inflation index is expensed over the lease term as it is payable. See Note 17 for additional information. Goodwill and Other Intangible Assets Goodwill represents the difference between the purchase price and the related underlying tangible and identifiable intangible net asset fair values resulting from business acquisitions. Annually in Q4, or earlier if conditions indicate it is necessary, the carrying value of the reporting unit is compared to an estimate of its fair value. If the estimated fair value of the reporting unit is less than the carrying value, goodwill is impaired and is written down to its estimated fair value. Goodwill is assigned to and the fair value is tested at the reporting unit level. In 2018 and 2017, we evaluated goodwill and intangible assets using six reporting units: the Americas, Red Thread, EMEA, Asia Pacific, Designtex and PolyVision. See Note 10 for additional information. Other intangible assets subject to amortization consist primarily of proprietary technology, trademarks, customer relationships and non-compete agreements and are amortized over their estimated useful economic lives using the straight-line method. Other intangible assets not subject to amortization, consisting of certain trademarks, are accounted for and evaluated for potential impairment in a manner consistent with goodwill. See Note 10 for additional information. Contingencies Loss contingencies are accrued if the loss is probable and the amount of the loss can be reasonably estimated. Legal costs associated with potential loss contingencies are expensed as incurred. We are involved in litigation from time to time in the ordinary course of our business. Based on known information, we do not believe we are party to any lawsuit or proceeding, individually and in the aggregate, that is likely to have a material adverse impact on the consolidated financial statements. Self-Insurance We are self-insured for certain losses relating to domestic workers’ compensation, product liability and employee medical, dental, and short-term disability claims. We purchase insurance coverage to reduce our exposure to significant levels of certain of these claims. Self-insured losses are accrued based upon estimates of the aggregate liability for uninsured claims incurred as of the balance sheet date using current and historical claims experience and certain actuarial assumptions. These estimates are subject to uncertainty due to a variety of factors, including extended lag times in the reporting and resolution of claims, and trends or changes in claim settlement patterns, insurance industry practices and legal interpretations. As a result, actual costs could differ significantly from the estimated amounts. Adjustments to estimated reserves are recorded in the period in which the change in estimate occurs. Net Reserve for Estimated Domestic Workers' Compensation Claims Year Ended February 23, 2018 February 24, 2017 Assets: Long-term - Other assets $ 4.4 $ 4.0 Liabilities: Current - Accrued expenses - other 3.0 2.4 Long-term - Other long-term liabilities 12.9 13.9 15.9 16.3 Net reserve $ 11.5 $ 12.3 The other long-term asset balance represents the portion of claims expected to be paid by a third party insurance provider. Net Reserve for Estimated Product Liability Claims Year Ended February 23, 2018 February 24, 2017 Assets: Long-term - Other long-term assets $ 2.7 $ 2.4 Liabilities: Current - Accrued expenses - other 1.3 1.4 Long-term - Other long-term liabilities 6.7 7.3 8.0 8.7 Net reserve $ 5.3 $ 6.3 The other long-term asset balance represents the portion of claims expected to be paid by a third party insurance provider. The estimate for unpaid employee medical, dental, and short-term disability claims incurred as of February 23, 2018 and February 24, 2017 was $3.9 and $4.5 , respectively, and is recorded within Accrued expenses: Other on the Consolidated Balance Sheets. Product Warranties We offer warranties ranging from 3 years to lifetime for most products, subject to certain exceptions. These warranties provide for the free repair or replacement of any covered product, part or component that fails during normal use because of a defect in materials or workmanship. The accrued liability for product warranties is based on an estimated amount needed to cover product warranty costs, including product recall and retrofit costs, incurred as of the balance sheet date determined by historical claims experience and our knowledge of current events and actions. Roll-Forward of Accrued Year Ended February 23, February 24, February 26, Balance as of beginning of period $ 41.3 $ 42.1 $ 39.4 Accruals related to product warranties, recalls and retrofits 10.6 19.5 18.1 Reductions for settlements (15.8 ) (20.1 ) (16.0 ) Currency translation adjustments 0.7 (0.2 ) 0.6 Balance as of end of period $ 36.8 $ 41.3 $ 42.1 Our reserve for estimated settlements expected to be paid beyond one year as of February 23, 2018 and February 24, 2017 was $18.7 and $20.9 , respectively, and is included in Other long-term liabilities on the Consolidated Balance Sheets. Pension and Other Post-Retirement Benefits We sponsor a number of domestic and foreign plans to provide pension benefits and medical and life insurance benefits to retired employees. We measure the net over-funded or under-funded positions of our defined benefit pension plans and post-retirement benefit plans as of the end of each fiscal year and display that position as an asset or liability on the Consolidated Balance Sheets. Any unrecognized prior service credit (cost) or experience gains (losses) are reported, net of tax, as a component of Accumulated other comprehensive income (loss) in shareholders’ equity. See Note 13 for additional information. Environmental Matters Environmental expenditures related to current operations are expensed or capitalized as appropriate. Expenditures related to an existing condition allegedly caused by past operations, and not associated with current or future revenue generation, are expensed. Generally, the timing of these accruals coincides with completion of a feasibility study or our commitment to a formal plan of action. Liabilities are recorded on a discounted basis as site-specific plans indicate the amount and timing of cash payments are fixed and reliably determinable. We have ongoing monitoring and identification processes to assess how known exposures are progressing against the accrued cost estimates, as well as processes to identify other potential exposures. Environmental Contingencies Year Ended February 23, 2018 February 24, 2017 Current: Accrued expenses - other $ 0.7 $ 0.6 Long-Term: Other long-term liabilities 2.5 3.3 Total environmental contingencies (discounted) $ 3.2 $ 3.9 The environmental liabilities were discounted using a rate of 3.5% and 4.0% as of February 23, 2018 and February 24, 2017 . Our undiscounted liabilities were $3.7 and $4.8 as of February 23, 2018 and February 24, 2017 , respectively. Based on our ongoing evaluation of these matters, we believe we have accrued sufficient reserves to absorb the costs of all known environmental assessments and the remediation costs of all known sites. Asset Retirement Obligations We record all known asset retirement obligations for which the liability’s fair value can be reasonably estimated. We also have known conditional asset retirement obligations that are not reasonably estimable due to insufficient information about the timing and method of settlement of the obligation. Accordingly, these obligations have not been recorded in the consolidated financial statements. A liability for these obligations will be recorded in the period when sufficient information regarding timing and method of settlement becomes available to make a reasonable estimate of the liability’s fair value. In addition, there may be conditional asset retirement obligations we have not yet discovered, and therefore, these obligations also have not been included in the consolidated financial statements. Revenue Recognition Revenue consists substantially of product sales and related service revenue. Product sales are reported net of discounts and are recognized when title and risks associated with ownership have passed to the dealer or customer. Under sales contracts with our dealers, this typically occurs when product is shipped. In cases where we have a direct sales contract with the customer, title and risks associated with ownership often transfer upon delivery or acceptance by the customer. Revenue from services is recognized when the services have been rendered. Revenue does not include sales tax, as we consider ourselves a pass-through entity for collecting and remitting sales taxes. Cost of Sales Cost of sales includes material, labor and overhead. Included within these categories are such items as compensation expense, logistics costs (including shipping and handling costs), facilities expense, depreciation and warranty expense. Operating Expenses Operating expenses include selling, general and administrative expenses not directly related to the procurement, manufacturing and delivery of our products. Included in these expenses are items such as employee compensation expense, research and development expense, facilities expense, depreciation, royalty expense, information technology services, professional services and travel and entertainment expense. Research and Development Expenses Research and development expenses, which we define as expenses related to the investigative activities we conduct to improve existing products and procedures or to lead to the development of new products and procedures, are expensed as incurred and were $44.0 for 2018 , $35.8 for 2017 and $33.0 for 2016 . Income Taxes Deferred income tax assets and liabilities are recognized for the estimated future tax consequences attributable to temporary differences between the consolidated financial statements carrying amounts of existing assets and liabilities and their respective tax bases. These deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which the temporary differences are expected to reverse. The effect of a change in tax rates on deferred income tax assets and liabilities is recognized in the Consolidated Statements of Income in the period that includes the enactment date. We establish valuation allowances against deferred tax assets when it is more likely than not that all or a portion of the deferred tax assets will not be realized. All evidence, both positive and negative, is identified and considered in making the determination. Future realization of the existing deferred tax asset depends, in part, on the existence of sufficient taxable income of appropriate character within the carryforward period available under tax law applicable in the jurisdiction in which the related deferred tax assets were generated. We have net operating loss carryforwards available in certain jurisdictions to reduce future taxable income. Future tax benefits associated with net operating loss carryforwards are recognized to the extent that realization of these benefits is considered more likely than not. This determination is based on the expectation that related operations will be sufficiently profitable or various tax, business and other planning strategies will enable us to utilize the net operating loss carryforwards. In making this determination we consider all available positive and negative evidence. To the extent that available evidence raises doubt about the realization of a deferred income tax asset, a valuation allowance is established. We record reserves for uncertain tax positions except to the extent it is more likely than not that the tax position will be sustained on audit, based on the technical merits of the position. Periodic changes in reserves for uncertain tax positions are reflected in the provision for income taxes. See Note 15 for additional information. Share-Based Compensation Our share-based compensation consists of restricted stock units and performance units. Our policy is to expense share-based compensation using the fair-value based method of accounting for all awards granted, modified or settled. Restricted stock units and performance units are credited to shareholders' equity as they are expensed over the requisite service periods based on the grant date fair value of the shares expected to be issued. See Note 16 for additional information. Financial Instruments The carrying amounts of our financial instruments, consisting of cash and cash equivalents, accounts and notes receivable, accounts and notes payable and certain other liabilities, approximate their fair value due to their relatively short maturities. Our short-term investments, foreign exchange forward contracts and long-term investments are measured at fair value on the Consolidated Balance Sheets. Our total debt is carried at cost and was $295.0 and $297.4 as of February 23, 2018 and February 24, 2017 , respectively. The fair value of our total debt is measured using a discounted cash flow analysis based on current market interest rates for similar types of instruments and was approximately $316 and $330 as of February 23, 2018 and February 24, 2017 , respectively. The estimation of the fair value of our total debt is based on Level 2 fair value measurements. See Note 6 and Note 12 for additional information. We periodically use derivative financial instruments to manage exposures to movements in interest rates and foreign exchange rates. The use of these financial instruments modifies the exposure of these risks with the intention to reduce our risk of short-term volatility. We do not use derivatives for speculative or trading purposes. Foreign Exchange Forward Contracts A portion of our revenue and earnings is exposed to changes in foreign exchange rates. We seek to manage our foreign exchange risk largely through operational means, including matching same currency revenue with same currency costs and same currency assets with same currency liabilities. Foreign exchange risk is also partially managed through the use of derivative instruments. Foreign exchange forward contracts serve to reduce the risk of conversion or translation of certain foreign denominated transactions, assets and liabilities. We primarily use derivatives for intercompany working capital loans and certain forecasted currency flows from foreign-denominated transactions. The foreign exchange forward contracts relate to the euro, the Mexican peso, the United Kingdom pound sterling, the Canadian dollar, the Australian dollar, the Malaysian ringgit and the Japanese yen. See Note 6 for additional information. Assets and liabilities related to derivative instruments as of February 23, 2018 and February 24, 2017 are summarized below: Consolidated Balance Sheets February 23, February 24, Other current assets $ 2.1 $ 3.5 Accrued expenses (1.4 ) (0.9 ) Total net fair value of derivative instruments (1) $ 0.7 $ 2.6 ________________________ (1) The notional amounts of the outstanding foreign exchange forward contracts were $95.7 as of February 23, 2018 and $101.2 as of February 24, 2017 . Net gains (losses) recognized from derivative instrument activity in 2018 , 2017 and 2016 are summarized below: Gain (Loss) Recognized in Consolidated Statements of Income Year Ended February 23, February 24, February 26, Cost of sales $ 2.8 $ (1.1 ) $ (0.8 ) Operating expenses 0.6 0.8 (0.8 ) Other income, net (4.8 ) 1.2 3.0 Total net gain (loss) $ (1.4 ) $ 0.9 $ 1.4 The net gains or losses recognized from derivative instruments in other income, net are largely offset by related foreign currency gains or losses on our intercompany loans and intercompany accounts payable.

New Accounting Standards

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Standards	NEW ACCOUNTING STANDARDS Accounting Standards Issued But Not Yet Adopted In February 2018, the Financial Accounting Standards Board ("FASB"), issued Accounting Standards Update ("ASU") No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220), to address the impact of the U.S. Tax Cuts and Jobs Act (the "Tax Act") on tax effects presented in other comprehensive income. The amended guidance allows a reclassification from accumulated other comprehensive income to retained earnings for the tax effects of items within accumulated other comprehensive income resulting from the Tax Act. The amended guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. The amendments may be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715) , to improve the presentation of net periodic pension cost and net periodic post-retirement benefit cost. The amended guidance requires that an employer disaggregate the service cost component from the other components of net benefit cost, provides explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement, and allows only the service cost component of net benefit cost to be eligible for capitalization. The amended guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. We plan to apply the amended guidance beginning in Q1 2019 using the practical expedient which allows entities to use information previously disclosed in their pension and other postretirement benefit plans note as the estimation basis to apply the retrospective presentation requirements. We expect to reclassify approximately $1 of net expenses for 2018 and $2 of net credits for 2017 from Cost of sales and Operating expenses to Other income, net on our Consolidated Statements of Income . There will be no impact to Net income on our Consolidated Statements of Income as a result of this change. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) , which replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses. The amended guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, with early adoption permitted for the fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. We are currently evaluating the impact of the adoption of this standard on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which establishes a new lease accounting model for lessees. The updated guidance requires an entity to recognize assets and liabilities arising from financing and operating leases, along with additional qualitative and quantitative disclosures. The amended guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. We expect the adoption of this guidance will result in an increase in assets and liabilities on our Consolidated Balance Sheets, and we are currently evaluating the extent of this increase. In May 2014, the FASB issued ASU No. 2014-09, Revenue From Contracts with Customers (Topic 606) , which establishes a new standard on revenue recognition. The new standard (along with its related clarifying amendments) 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 guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted for fiscal years beginning after December 15, 2016. We have evaluated the impact that will result from adoption of the new standard, and based on analysis performed as of February 23, 2018, we do not anticipate a significant impact on our consolidated financial statements except for enhanced disclosures. We currently plan to apply the new standard using the modified retrospective method in Q1 2019.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Earnings per share is computed using the two-class method. The two-class method determines earnings per share for each class of common stock and participating securities according to dividends or dividend equivalents and their respective participation rights in undistributed earnings. Participating securities represent restricted stock units in which the participants have non-forfeitable rights to dividend equivalents during the performance period. Diluted earnings per share includes the effects of certain performance units in which the participants have forfeitable rights to dividend equivalents during the performance period.

Fair Value

Fair Value	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value	FAIR VALUE Fair value measurements are classified under the following hierarchy: Level 1 — Inputs based on quoted market prices for identical assets or liabilities in active markets at the measurement date. Level 2 — Inputs based on quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs or significant value-drivers are observable in active markets. Level 3 — Inputs reflect management’s best estimate of what market participants would use to price the asset or liability at the measurement date in model-driven valuations. The inputs are unobservable in the market and significant to the instrument’s valuation. Fair value measurements are classified according to the lowest level input or value-driver that is significant to the valuation. A measurement may therefore be classified within Level 3 even though there may be other significant inputs that are readily observable. Assets and liabilities measured at fair value in our Consolidated Balance Sheets as of February 23, 2018 and February 24, 2017 are summarized below: Fair Value of Financial Instruments February 23, 2018 Level 1 Level 2 Level 3 Total Assets: Cash and cash equivalents $ 283.1 $ — $ — $ 283.1 Restricted cash 2.5 — — 2.5 Foreign exchange forward contracts — 2.1 — 2.1 Auction rate securities — — 3.5 3.5 $ 285.6 $ 2.1 $ 3.5 $ 291.2 Liabilities: Foreign exchange forward contracts $ — $ (1.4 ) $ — $ (1.4 ) $ — $ (1.4 ) $ — $ (1.4 ) Fair Value of Financial Instruments February 24, 2017 Level 1 Level 2 Level 3 Total Assets: Cash and cash equivalents $ 197.1 $ — $ — $ 197.1 Restricted cash 2.5 — — 2.5 Managed investment portfolio and other investments Corporate debt securities — 33.6 — 33.6 U.S. agency debt securities — 18.6 — 18.6 Municipal debt securities — 15.1 — 15.1 Asset-backed securities — 3.7 — 3.7 U.S. government debt securities 2.4 — — 2.4 Foreign exchange forward contracts — 3.5 — 3.5 Auction rate securities — — 3.5 3.5 $ 202.0 $ 74.5 $ 3.5 $ 280.0 Liabilities: Foreign exchange forward contracts $ — $ (0.9 ) $ — $ (0.9 ) $ — $ (0.9 ) $ — $ (0.9 ) Managed Investment Portfolio and Other Investments Our managed investment portfolio has historically consisted of U.S. agency debt securities, corporate debt securities, asset backed securities, U.S. government debt securities and municipal debt securities. As we converted the balance of our portfolio to cash in Q3 2018, there is no cost basis for our investments on February 23, 2018 . The cost basis for these investments was $73.4 on February 24, 2017 . There were no net unrealized losses for 2018 and $0.1 for 2017 . Foreign Exchange Forward Contracts From time to time, we enter into forward contracts to reduce the risk of translation into U.S. dollars of certain foreign-denominated transactions, assets and liabilities. We primarily hedge intercompany working capital loans and certain forecasted currency flows from foreign-denominated transactions. The fair value of foreign exchange forward contracts is based on a valuation model that calculates the differential between the contract price and the market-based forward rate. Auction Rate Securities As of February 23, 2018 , we held auction rate securities (“ARS”) with a total par value of $6.5 and an adjusted fair value of $3.5 . The difference between par value and fair value is comprised of other-than-temporary impairment losses and unrealized losses on our ARS investments of $2.5 and $0.5 , respectively. The investments other-than-temporarily impaired were impaired due to general credit declines, and the impairments were recorded in Investment income in the Consolidated Statements of Income prior to 2016. Unrealized losses are recorded in Accumulated other comprehensive income (loss) on the Consolidated Balance Sheets. The unrealized losses are due to changes in interest rates and are expected to fluctuate over the contractual term of the instruments. While there has been no payment default with respect to our ARS, these investments are not widely traded and therefore do not currently have a readily determinable market value. To estimate fair value, we used an internally-developed discounted cash flow analysis. Our discounted cash flow analysis considers, among other factors, (i) the credit ratings of the ARS, (ii) the credit quality of the underlying securities or the credit rating of issuers, (iii) the estimated timing and amount of cash flows, (iv) the formula applicable to each security which defines the penalty interest rate and (v) discount rates equal to the sum of (a) the yield on U.S. Treasury securities with a term through the estimated workout date plus (b) a risk premium based on similarly rated observable securities. A deterioration in market conditions or the use of different assumptions could result in a different valuation and additional impairments. For example, an increase to the discount rate of 100 basis points would reduce the estimated fair value of our investment in ARS by approximately $0.4 . Below is a roll-forward of assets and liabilities measured at estimated fair value using Level 3 inputs for the years ended February 23, 2018 and February 24, 2017 : Roll-forward of Fair Value Using Level 3 Inputs Auction Rate Securities Balance as of February 26, 2016 $ 4.4 Unrealized loss on investments (0.9 ) Balance as of February 24, 2017 $ 3.5 Unrealized loss on investments — Balance as of February 23, 2018 $ 3.5 There were no other-than-temporary impairments or transfers into or out of Level 3 during either 2018 or 2017 . Our policy is to value any transfers between levels of the fair value hierarchy based on end of period fair values.

Company-Owned Life Insurance [Abstract]
Company-Owned Life Insurance	COMPANY-OWNED LIFE INSURANCE Our investments in company-owned life insurance (“COLI”) policies are recorded at their net cash surrender value. A portion of our investments in COLI are intended to be utilized as a long-term funding source for post-retirement medical benefits, deferred compensation and defined pension plan obligations. The designation of our COLI investments as funding sources for our benefit obligations does not result in these investments representing a committed funding source for these obligations. They are subject to claims from creditors, and we can redesignate them to another purpose at any time. The net returns in cash surrender value, normal insurance expenses and any death benefit gains related to our investments in COLI policies ("COLI income") are recorded in Operating expenses on the Consolidated Statements of Income. COLI income is intended to offset the expense associated with long-term benefit plan obligations which are also recorded in Operating expenses on the Consolidated Statements of Income. COLI income totaled $10.3 in 2018, $9.5 in 2017 and $0.8 in 2016. The balances of our COLI investments as of February 23, 2018 and February 24, 2017 were as follows: Type Ability to Choose Net Return Target Asset Allocation as of February 23, 2018 Net Cash Surrender Value February 23, February 24, Whole life COLI policies No ability A rate of return set periodically by the Not applicable $ 124.3 $ 125.6 Variable life COLI policies Can allocate across a set of choices provided by the insurance companies Fluctuates depending on performance of underlying investments 30% fixed income; 70% equity 47.9 43.2 $ 172.2 $ 168.8

Goodwill & Other Intangible Assets	GOODWILL & OTHER INTANGIBLE ASSETS A summary of the changes in goodwill during the years ended February 23, 2018 and February 24, 2017 , by reportable segment, is as follows: Goodwill Americas EMEA Other Total Balance as of February 26, 2016 $ 87.9 $ — $ 18.5 $ 106.4 Currency translation adjustments 0.3 — — 0.3 Goodwill 89.9 265.0 116.5 471.4 Accumulated impairment losses (1.7 ) (265.0 ) (98.0 ) (364.7 ) Balance as of February 24, 2017 $ 88.2 $ — $ 18.5 $ 106.7 Acquisitions (1) 31.2 — — 31.2 Currency translation adjustments 0.3 — — 0.3 Goodwill 121.4 265.0 116.5 502.9 Accumulated impairment losses (1.7 ) (265.0 ) (98.0 ) (364.7 ) Balance as of February 23, 2018 $ 119.7 $ — $ 18.5 $ 138.2 ________________________ (1) In 2018, we acquired AMQ Solutions and certain assets of Tricom Vision Limited resulting in a goodwill addition in the Americas segment. See Note 18 for additional information. We compare the fair value of each reporting unit to its carrying value. If the fair value of the reporting unit exceeds the carrying value, goodwill is not impaired, and no further testing is required. If the fair value of the reporting unit is less than the carrying value, the difference is recorded as an impairment loss. We estimated the fair value of our reporting units using the income approach, which calculates the fair value of each reporting unit based on the present value of its estimated future cash flows. Cash flow projections are based on management's estimates of revenue growth rates and operating margins, taking into consideration industry and market conditions. The discount rates used are based on the weighted-average cost of capital adjusted for the relevant risk associated with business-specific characteristics and the uncertainty related to the reporting units' ability to execute on the projected cash flows. The estimation of the fair value of our reporting units represents a Level 3 measurement. Based on the results of the annual impairment test, we concluded that no goodwill impairment existed as of February 23, 2018 or February 24, 2017 . We will continue to evaluate goodwill, on an annual basis in Q4, and whenever events or changes in circumstances, such as significant adverse changes in business climate or operating results, changes in management's business strategy or significant declines in our stock price, indicate that there may be a potential indicator of impairment. As of February 23, 2018 and February 24, 2017 , our other intangible assets and related accumulated amortization consisted of the following: Other Intangible Assets February 23, 2018 February 24, 2017 Weighted Gross Accumulated Net Gross Accumulated Net Intangible assets subject to amortization: Proprietary technology 8.3 $ 26.8 $ 23.4 $ 3.4 $ 26.8 $ 23.0 $ 3.8 Trademarks (1) 9.9 11.2 9.9 1.3 9.0 9.0 — Non-compete agreements 6.2 1.2 1.2 — 1.6 1.6 — Dealer relationships (1) 11.0 25.5 0.4 25.1 — — — Other (1) 5.0 12.7 9.7 3.0 9.8 9.6 0.2 77.4 44.6 32.8 47.2 43.2 4.0 Intangible assets not subject to amortization: Trademarks and other n/a 12.8 — 12.8 12.8 — 12.8 $ 90.2 $ 44.6 $ 45.6 $ 60.0 $ 43.2 $ 16.8 ________________________ (1) In 2018, we acquired AMQ Solutions and certain assets of Tricom Vision Limited resulting in additional intangible assets in the Americas segment.

Short-Term Borrowings And Long-Term Debt	SHORT-TERM BORROWINGS AND LONG-TERM DEBT Debt Obligations Interest Rate Range as of February 23, 2018 Fiscal Year February 23, February 24, U.S. dollar obligations: Senior notes (1) 6.375% 2021 $ 249.1 $ 248.8 Revolving credit facilities (2)(4) 2022 — — Notes payable (3) 2.8% 2024 45.4 48.0 294.5 296.8 Foreign currency obligations: Revolving credit facilities (4) — — Notes payable 6.0% - 9.0% 0.3 0.3 Capitalized lease obligations 1.4% 2020 0.2 0.3 Total short-term borrowings and long-term debt 295.0 297.4 Short-term borrowings and current portion of long-term debt (5) 2.8 2.8 Long-term debt $ 292.2 $ 294.6 ________________________ (1) We have $250 of unsecured unsubordinated senior notes, due in February 2021 (“2021 Notes”). The 2021 Notes were issued at 99.953% of par value. The bond discount of $0.1 and direct debt issuance costs of $3.0 were deferred and are being amortized over the life of the 2021 Notes. Although the coupon rate of the 2021 Notes is 6.375% , the effective interest rate is 6.6% after taking into account the impact of the direct debt issuance costs, a deferred loss on interest rate locks related to the debt issuance and the bond discount. The 2021 Notes rank equally with all of our other unsecured unsubordinated indebtedness, and they contain no financial covenants. We may redeem some or all of the 2021 Notes at any time. The redemption price would equal the greater of (1) the principal amount of the notes being redeemed; or (2) the present value of the remaining scheduled payments of principal and interest discounted to the redemption date on a semi-annual basis at the comparable U.S. Treasury rate plus 45 basis points; plus, in both cases, accrued and unpaid interest. If the notes are redeemed within 3 months of maturity, the redemption price would be equal to the principal amount of the notes being redeemed plus accrued and unpaid interest. Amortization expense related to the direct debt issuance costs and bond discount on the 2021 Notes was $0.3 in 2018 , 2017 and 2016 . (2) We have a $125 global committed five-year bank facility which has an interest rate of LIBOR plus an applicable margin and is set to expire in September 2021. As of February 23, 2018 and February 24, 2017 , there were no borrowings outstanding under the facility, our availability was not limited, and we were in compliance with all covenants under the facility. In addition, we have revolving credit agreements of $47.0 which can be utilized to support bank guarantees, letters of credit, overdrafts and foreign exchange contracts. As of February 23, 2018 , we had $14.8 in outstanding bank guarantees and standby letters of credit against these agreements. We had no draws against our standby letters of credit during 2018 . (3) We have a $45.4 note payable with an original amount of $50.0 at a floating interest rate based on 30-day LIBOR plus 1.20% . The loan has a term of seven years and requires fixed monthly principal payments of $0.2 on a 20-year amortization schedule with a $32 balloon payment due in 2024 . The loan is secured by two corporate aircraft, contains no financial covenants and is not cross-defaulted to our other debt facilities. (4) We have unsecured uncommitted short-term credit facilities of up to $2.6 of U.S. dollar obligations and up to $24.6 of foreign currency obligations with various financial institutions available for working capital purposes as of February 23, 2018 . Interest rates are variable and determined at the time of borrowing. These credit facilities have no stated expiration date but may be changed or canceled by the banks at any time. There were no borrowings on these facilities as of February 23, 2018 and February 24, 2017 . (5) The weighted-average interest rate for short-term borrowings and the current portion of long-term debt was 2.8% as of February 23, 2018 and 1.8% as of February 24, 2017 . The annual maturities of short-term borrowings and long-term debt for each of the following five years are as follows: Fiscal Year Ending in February Amount 2019 $ 2.8 2020 2.7 2021 251.7 2022 2.6 2023 2.6 Thereafter 32.6 $ 295.0 Global Credit Facility Our $125 committed five-year unsecured revolving syndicated credit facility expires in 2022. At our option, and subject to certain conditions, we may increase the aggregate commitment under the facility by up to $75 by obtaining at least one commitment from one of the lenders. There are no borrowings outstanding under the facility. We can use borrowings under the facility for general corporate purposes, including friendly acquisitions. Interest on borrowings is based on the rate, as selected by us, between the following two options: • the greatest of the prime rate, the Federal fund effective rate plus 0.5%, and the Eurocurrency rate for a one month interest period plus 1%, plus the applicable margin as set forth in the credit agreement; or • the Eurocurrency rate plus the applicable margin as set forth in the credit agreement. The facility requires us to satisfy two financial covenants: • A maximum leverage ratio covenant, which is measured by the ratio of (x) indebtedness (as determined under the credit agreement) less unrestricted cash (as determined under the credit agreement) to (y) trailing four quarter Adjusted EBITDA (as determined under the credit agreement) and is required to be no greater than 3:1. (In the context of certain permitted acquisitions, we have a one-time ability, subject to certain conditions, to increase the maximum ratio to 3.25 to 1.0 for four consecutive quarters). • A minimum interest coverage ratio covenant, which is measured by the ratio of (y) trailing four quarter Adjusted EBITDA (as determined under the credit agreement) to (z) trailing four quarter interest expense and is required to be no less than 3.5:1. The facility does not include any restrictions on cash dividend payments or share repurchases. As of February 23, 2018 and February 24, 2017 , we were in compliance with all covenants under the facility.

Retirement Plan (the “Retirement Plan”). Company contributions, including discretionary profit sharing and 401(k) matching contributions, and employee 401(k) pre-tax contributions fund the Retirement Plan. All contributions are made to a trust which is held for the sole benefit of participants. Company contributions for our defined contribution retirement plans are discretionary. Total expense under all defined contribution retirement plans was $33.7 for 2018 , $32.7 for 2017 and $28.8 for 2016 . We expect to fund approximately $35.7 related to our defined contribution plans in 2019 , including funding related to our discretionary profit sharing contributions. Post-Retirement Medical Benefits We maintain post-retirement benefit plans that provide medical and life insurance benefits to certain North American-based retirees and eligible dependents. The plans were frozen to new participants in 2003. We accrue the cost of post-retirement benefits during the service periods of employees based on actuarial calculations for each plan. These plans are unfunded, but a portion of our investments in COLI policies are intended to be utilized as a long-term funding source for these benefit obligations. See Note 9 for additional information. While we do not expect the timing of cash flows to closely match, we intend to hold the policies until maturity, and we expect the policies will generate insufficient cash to cover the obligation payments over the next several years and generate excess cash in later years. In 2017, we made changes to certain retiree participation assumptions based on the results of our retiree participation experience study. These changes resulted in a reduction to the accumulated post-retirement projected benefit obligation of $17.8 . Defined Benefit Pension Plans Our defined benefit pension plans include various qualified foreign retirement plans as well as non-qualified supplemental retirement plans that are limited to a select group of management approved by the Compensation Committee. The benefit plan obligations for the non-qualified supplemental retirement plans are primarily related to the Steelcase Inc. Executive Supplemental Retirement Plan. This plan is unfunded, but a portion of our investments in COLI policies are intended to be utilized as a long-term funding source for these benefit obligations. See Note 9 for additional information. The funded status of our defined benefit pension plans (excluding our investments in COLI policies) is as follows: Defined Benefit Pension February 23, 2018 February 24, 2017 Qualified Plans Non-qualified Qualified Plans Non-qualified Foreign Domestic Foreign Plan assets $ 33.1 $ — $ 7.9 $ 38.8 $ — Projected benefit plan obligations 47.5 32.6 7.9 55.1 33.8 Funded status $ (14.4 ) $ (32.6 ) $ — $ (16.3 ) $ (33.8 ) Short-term asset $ — $ — $ — $ 0.2 $ — Long-term asset 0.5 — — — — Current liability (0.1 ) (3.8 ) — (0.1 ) (3.5 ) Long-term liability (14.8 ) (28.8 ) — (16.4 ) (30.3 ) Total benefit plan obligations $ (14.4 ) $ (32.6 ) $ — $ (16.3 ) $ (33.8 ) Accumulated benefit obligation $ 42.5 $ 32.4 $ 7.9 $ 51.0 $ 33.5 As of February 23, 2018 , we had one qualified foreign plan in an over-funded status, as plan assets of $32.8 exceeded projected benefit plan obligations of $32.3 by $0.5 . As of February 24, 2017, we had two qualified domestic plans in fully funded status and one qualified foreign plan in an over-funded status, as plan assets of $18.4 exceeded projected benefit plan obligations of $18.2 by $0.2 . In 2018, we purchased annuities to settle the benefit plan obligations for these three plans, resulting in a charge of $7.1 for losses previously accumulated in other comprehensive income for these plans.

measurement dates for our retiree benefit plans are consistent with our fiscal year-end. Accordingly, we select discount rates to measure our benefit obligations that are consistent with market indices at the end of each year. In evaluating the expected return on plan assets, we consider the expected long-term rate of return on plan assets based on the specific allocation of assets for each plan, an analysis of current market conditions and the views of leading financial advisors and economists. The assumed healthcare cost trend was 7.01% for pre-age 65 retirees as of February 23, 2018 , gradually declining to 4.50% after nine years. As of February 24, 2017 , the assumed healthcare cost trend was 7.28% for pre-age 65 retirees, gradually declining to 4.50% after ten years. Post-age 65 trend rates are not applicable as our plan provides a fixed subsidy for post-age 65 benefits. A one percentage point change in assumed healthcare cost trend rates would have had the following effects as of February 23, 2018 : Health Cost Trend Sensitivity One percentage One percentage Effect on total of service and interest cost components $ — $ — Effect on post-retirement benefit obligation $ 0.2 $ (0.2 ) Plan Assets The investments of the foreign plans are managed by third-party investment managers who follow local regulations. In general, the investment strategy is designed to accumulate a diversified portfolio among markets, asset classes or individual securities in order to reduce market risk and assure that the pension assets are available to pay benefits as they come due. Our pension plans’ weighted-average investment allocation strategies and weighted-average target asset allocations by asset category as of February 23, 2018 and February 24, 2017 are reflected in the following table. The target allocations are established by the investment committees of each plan in consultation with external advisors after consideration of the associated risk and expected return of the underlying investments.

The fair value of the pension plan assets as of February 23, 2018 and February 24, 2017 , by asset category are as follows: Fair Value of Pension Plan Assets February 23, 2018 Level 1 Level 2 Level 3 Total Cash and cash equivalents $ 0.2 $ — $ — $ 0.2 Equity securities: International — 25.8 — 25.8 Fixed income securities: Bond funds — 5.5 — 5.5 Other investments: Guaranteed insurance contracts (1) — — 0.4 0.4 Property and property funds — 1.2 — 1.2 $ 0.2 $ 32.5 $ 0.4 $ 33.1 Fair Value of Pension Plan Assets February 24, 2017 Level 1 Level 2 Level 3 Total Cash and cash equivalents $ 6.3 $ — $ — $ 6.3 Equity securities: International — 23.4 — 23.4 Fixed income securities: Bond funds — 13.6 — 13.6 Other investments: Guaranteed insurance contracts (1) — — 0.7 0.7 Group annuity contract (2) — — 1.9 1.9 Property funds 0.8 — — 0.8 $ 7.1 $ 37.0 $ 2.6 $ 46.7 ________________________ (1) Guaranteed insurance contracts are valued at book value, which approximates fair value, and are calculated using the prior year balance plus or minus investment returns and changes in cash flows. (2) Group annuity contracts were valued utilizing a discounted cash flow model. The term “cash flow” refers to the future principal and interest payments we expected to receive on a given asset in the general account. The model projected future cash flows separately for each investment period and each category of investment. There were no material transfers between Level 1 and Level 2 of the fair value hierarchy for any periods presented. Below is a roll-forward of plan assets measured at estimated fair value using Level 3 inputs for the years ended February 23, 2018 and February 24, 2017 : Roll-forward of Fair Value Using Level 3 Inputs Group Guaranteed Balance as of February 26, 2016 $ 2.0 $ 1.0 Unrealized return on plan assets, including changes in foreign exchange rates 0.1 — Purchases, sales, and other, net (0.2 ) (0.3 ) Balance as of Februa ry 24, 2017 $ 1.9 $ 0.7 Unrealized return on plan assets, including changes in foreign exchange rates — 0.1 Purchases, sales, and other, net (1.9 ) (0.4 ) Balance as of Februa ry 23, 2018 $ — $ 0.4 We expect to contribute approximately $5 to our pension plans and fund approximately $4 related to our post-retirement plans in 2019. The estimated future benefit payments under our pension and post-retirement plans are as follows: Fiscal Year Ending in February Pension Plans Post-retirement Plans 2019 $ 5.0 $ 3.6 2020 4.4 3.6 2021 3.7 3.5 2022 3.7 3.5 2023 4.5 3.5 2024 - 2028 25.6 16.1 Multi-Employer Pension Plan Our subsidiary SC Transport Inc. contributes to the Central States, Southeast and Southwest Areas Pension Fund based on obligations arising from a collective bargaining agreement covering 14 SC Transport Inc. employees. This plan provides retirement benefits to participants based on their service to contributing employers. The benefits are paid from assets held in trust for that purpose. Trustees are appointed by employers and unions; however, we are not a trustee. The trustees typically are responsible for determining the level of benefits to be provided to participants and for such matters as the investment of the assets and the administration of the plan. Based on the most recent information available, we believe that the projected benefit obligations in this multi-employer plan significantly exceed the value of the assets held in trust to pay benefits. Because we are one of a number of employers contributing to this plan, it is difficult to ascertain what the exact amount of the under-funding would be, although we anticipate the contribution per participating employee will increase at each contract renegotiation. We believe that funding levels have not changed significantly since year-end. The risks of participating in a multi-employer plan are different from the risks associated with single-employer plans in the following respects: • Assets contributed to the multi-employer plan by one employer may be used to provide benefits to employees of other participating employers. • If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. • If a participating employer chooses to stop participating in a multi-employer plan or otherwise has participation in the plan drop below certain levels, that employer may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability. Our participation in this plan is outlined in the tables below. Expense is recognized at the time our contributions are funded, in accordance with applicable accounting standards. Any adjustment for a withdrawal liability would be recorded at the time the liability is both probable and can be reasonably determined. The most recent estimate of our potential withdrawal liability is $27.7 .

Among other factors, red zone status plans are generally less than 65 percent funded and are considered in critical status.

The following table describes the expiration of the collective bargaining agreement associated with the multi-employer plan in which we participate: Pension Fund Total Collective Bargaining Agreements Expiration Date (1) % of Associates Under Collective Bargaining Agreement Over 5% Contribution in 2018 Central States, Southeast and Southwest Areas Pension Fund 1 3/31/2018 0.1% No ________________________ (1) The renewal for the collective bargaining agreement is currently in the negotiation process. In the absence of a renewal agreement, the Central States, Southeast and Southwest Areas Pension Fund will continue to operate under the expired agreement and bill the required rates. On the date of issuance of these financial statements, the Form 5500 was not available for the plan year ending in 2017 . Deferred Compensation Programs We maintain four deferred compensation programs. The first deferred compensation program is closed to new entrants. In this program, certain employees elected to defer a portion of their compensation in return for a fixed benefit to be paid in installments beginning when the participant reaches age 70. Under the second plan, certain employees may elect to defer a portion of their compensation. The third plan is intended to restore retirement benefits that would otherwise be paid under the Retirement Plan but are precluded as a result of the limitations on eligible compensation under Internal Revenue Code Section 401(a)(17). Under the fourth plan, our non-employee directors may elect to defer all or a portion of their board retainer and committee fees. The deferred amounts in the last three plans earn a return based on the investment option selected by the participant. These deferred compensation obligations are unfunded, but a portion of our investments in COLI policies are intended to be utilized as a long-term funding source for these deferred compensation obligations. See Note 9 for additional information. Deferred compensation expense, which represents annual participant earnings on amounts that have been deferred, and restoration retirement benefits were $5.9 for 2018 , $8.5 for 2017 and $5.9 for 2016 .

Capital Structure	CAPITAL STRUCTURE Terms of Class A Common Stock and Class B Common Stock The holders of common stock are generally entitled to vote as a single class on all matters upon which shareholders have a right to vote, subject to the requirements of applicable laws and the rights of any outstanding series of preferred stock to vote as a separate class. Each share of Class A Common Stock entitles its holder to one vote, and each share of Class B Common Stock entitles its holder to 10 votes. Each share of Class B Common Stock is convertible into a share of Class A Common Stock on a one-for-one basis (i) at the option of the holder at any time, (ii) upon transfer to a person or entity which is not a Permitted Transferee (as defined in our Second Restated Articles of Incorporation, as amended), (iii) with respect to shares of Class B Common Stock acquired after February 20, 1998, at such time as a corporation, partnership, limited liability company, trust or charitable organization holding such shares ceases to be controlled or owned 100% by Permitted Transferees and (iv) on the date on which the number of shares of Class B Common Stock outstanding is less than 15% of all of the then outstanding shares of common stock (calculated without regard to voting rights). Except for the voting and conversion features described above, the terms of Class A Common Stock and Class B Common Stock are generally similar. That is, the holders are entitled to equal dividends when declared by our Board of Directors and generally will receive the same per share consideration in the event of a merger and be treated on an equal per share basis in the event of a liquidation or winding up of Steelcase Inc. In addition, we are not entitled to issue additional shares of Class B Common Stock, or issue options, rights or warrants to subscribe for additional shares of Class B Common Stock, except that we may make a pro rata offer to all holders of common stock of rights to purchase additional shares of the class of common stock held by them, and any dividend payable in common stock will be paid in the form of Class A Common Stock to Class A holders and Class B Common Stock to Class B holders. Neither class of stock may be split, divided or combined unless the other class is proportionally split, divided or combined. Preferred Stock Our Second Restated Articles of Incorporation, as amended, authorize our Board of Directors, without any vote or action by our shareholders, to create one or more series of preferred stock up to the limit of our authorized but unissued shares of preferred stock and to fix the designations, preferences, rights, qualifications, limitations and restrictions thereof, including the voting rights, dividend rights, dividend rate, conversion rights, terms of redemption (including sinking fund provisions), redemption price or prices, liquidation preferences and the number of shares constituting any series.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES In Q4 2018, the U.S. government enacted the Tax Act, which was effective January 1, 2018. The Tax Act makes broad and complex changes to the U.S. tax code that affect 2018 and future periods. The following is a summary of the key corporate income tax provisions of the Tax Act: • reduced the U.S. federal corporate income tax rate from 35% to 21%, • implemented a one-time tax on the deemed repatriation of undistributed non-U.S. subsidiary earnings and generally eliminated the U.S. federal corporate income taxes on dividends from foreign subsidiaries, • included global intangible low-taxed income ("GILTI") provisions, which impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations, and • included base-erosion and anti-abuse tax ("BEAT") provisions, which eliminate the deduction of certain base-erosion payments made to related foreign corporations, and imposed a minimum tax if greater than regular tax. The staff of the U.S. Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 (“SAB 118”) to provide guidance on the accounting and reporting impacts of the Tax Act. SAB 118 states that, in situations where companies do not have enough information to complete the accounting in the period of enactment, a company must either: 1) record an estimated provisional amount if the impact of the change can be reasonably estimated, or 2) continue to apply the accounting guidance that was in effect immediately prior to the Tax Act if the impact of the change cannot be reasonably estimated. If estimated provisional amounts are recorded, or if no amounts are recorded because the impact cannot be reasonably estimated, SAB 118 provides a measurement period of no longer than one year during which companies should adjust those amounts as additional information becomes available. We have made reasonable estimates of the impact of the Tax Act and have recorded provisional amounts as follows: • We recorded a charge of $23.9 due to the remeasurement of our deferred taxes. While we were able to make a reasonable estimate of the impact of the reduction in the corporate tax rate, the final impact may be affected by other elements related to the Tax Act including, but not limited to, our calculation of deemed repatriation of deferred foreign income and the state tax effect of adjustments made to federal temporary differences. • We recorded a charge of $4.0 due to the net tax on deemed repatriation of net undistributed earnings of our non-U.S. subsidiaries. In order to finalize the impact of the tax on deemed repatriation, we must determine the amount of earnings of certain foreign subsidiaries as well as the amount of non-U.S. income taxes paid on these earnings. In Q4 2018, we were able to make reasonable estimates of these amounts; however, we are continuing to gather information to more precisely calculate the tax on deemed repatriation. We were not able to reasonably estimate, and therefore have not recorded, deferred taxes with respect to the GILTI provisions. We have not yet determined our policy election with respect to whether to record deferred taxes on basis differences that are expected to affect the amount of GILTI inclusions upon reversal or to record the impact of the GILTI tax in the period in which that tax is incurred. We have not included any impacts of BEAT in our consolidated financial statements for 2018, because this provision does not apply until 2019. Provision for Income Taxes The provision for income taxes on income before income taxes consists of: Provision for Income Taxes—Expense Year Ended February 23, February 24, February 26, Current income taxes: Federal $ 15.0 $ 18.4 $ 47.7 State and local 0.8 9.5 12.5 Foreign 12.1 17.0 12.6 27.9 44.9 72.8 Deferred income taxes: Federal 37.9 21.4 (12.7 ) State and local 7.0 1.2 (3.3 ) Foreign 8.0 4.2 (52.3 ) 52.9 26.8 (68.3 ) Income tax expense $ 80.8 $ 71.7 $ 4.5 Income taxes were based on the following sources of income before income tax expense: Source of Income Before Income Tax Expense Year Ended February 23, February 24, February 26, Domestic $ 120.2 $ 136.0 $ 114.9 Foreign 41.3 60.3 59.9 $ 161.5 $ 196.3 $ 174.8 The total income tax expense we recognized is reconciled to that computed by applying the U.S. federal blended statutory tax rate of 32.9% for 2018 and 35.0% for 2017 and 2016, as follows: Income Tax Provision Reconciliation Year Ended February 23, February 24, February 26, Tax expense at the U.S. federal statutory rate $ 53.2 $ 68.7 $ 61.2 Impact of the Tax Act (1) 27.9 — — State and local income taxes, net of federal 6.7 6.5 6.7 Valuation allowance provisions and adjustments (2) 0.4 (2.2 ) (59.9 ) Foreign investment tax credits (3) (1.6 ) — (1.5 ) COLI income (4) (3.4 ) (3.3 ) (0.7 ) Foreign operations, less applicable foreign tax credits (5) 1.4 (2.0 ) (1.6 ) Impact of change to non-U.S. federal statutory tax rates (6) 4.0 9.3 (0.1 ) Research tax credit (2.3 ) (1.8 ) (1.9 ) Tax reserve adjustments (7) (0.2 ) (5.3 ) — Other (5.3 ) 1.8 2.3 Total income tax expense recognized $ 80.8 $ 71.7 $ 4.5 ________________________ (1) We remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which are generally 21%. Those items that reversed in 2018 were remeasured using a tax rate of 32.9% . We have recorded a provisional decrease of $23.9 with respect to the Tax Act in 2018. As required by the Tax Act, we have recorded a provisional tax liability of $4.0 related to the U.S. federal income taxes on approximately $76.2 of undistributed earnings of our non-U.S. subsidiaries, net of $12.0 of related U.S. foreign tax credits. (2) The valuation allowance provisions were based on current year activity, and the valuation allowance adjustments were based on various factors, which are further detailed below. In Q4 2015, we implemented changes in EMEA to align our tax structure with the management of our globally integrated business. Our U.S. parent company became the principal in a contract manufacturing model with Steelcase European subsidiaries. In Q4 2016, we reached the conclusion that there was sufficient positive evidence, including acceptance of our new tax structure by the U.S. Internal Revenue Service, sustained profitability in our French subsidiaries and other factors, which caused us to reverse valuation allowances of $56.0 recorded against net deferred tax assets in France. (3) Investment tax credits were granted by the Czech Republic for investments in qualifying manufacturing equipment. (4) The increase in the cash surrender value of COLI policies, net of normal insurance expenses, plus death benefit gains are non-taxable. (5) The foreign operations, less applicable foreign tax credits, amounts include the rate differential between local statutory rates and the U.S. rate on foreign operations. (6) Reductions to the French corporate tax rate resulted in the revaluation of certain deferred tax assets of our French tax group, causing increases to income tax expense of $4.0 and $7.9 in 2018 and 2017, respectively. During 2017, reductions to the United Kingdom corporate tax rate increased tax expense by $1.5 . (7) Adjustments in 2017 related to a French income tax audit that was settled in 2017 . Deferred Income Taxes The significant components of deferred income taxes are as follows: Deferred Income Taxes February 23, February 24, Deferred income tax assets: Employee benefit plan obligations and deferred compensation $ 55.8 $ 108.8 Foreign and domestic net operating loss carryforwards 55.8 57.0 Reserves and accruals 18.9 29.8 Tax credit carryforwards 31.8 17.4 Other, net 16.1 21.2 Total deferred income tax assets 178.4 234.2 Valuation allowances (9.5 ) (7.9 ) Net deferred income tax assets 168.9 226.3 Deferred income tax liabilities: Property, plant and equipment 28.4 40.9 Intangible assets 3.4 3.6 Prepaid expenses 1.7 3.1 Total deferred income tax liabilities 33.5 47.6 Net deferred income taxes $ 135.4 $ 178.7 Net deferred income taxes is comprised of the following components: Deferred income tax assets—non-current 135.4 179.6 Deferred income tax liabilities—non-current — (0.9 ) At February 23, 2018 , the valuation allowance of $9.5 included $9.0 relating to foreign deferred tax assets. In updating our assessment of the ultimate realization of deferred tax assets, we considered the following factors: • the nature, frequency and severity of cumulative losses in recent years, • the predictability of future income, • prudent and feasible tax planning strategies that could be implemented to protect the loss of the deferred tax assets and • the effect of reversing taxable temporary differences. Based on our evaluation of these factors, particularly increasing cumulative losses, we were unable to assert that it is more likely than not that the deferred tax assets in our owned dealers in France and the United Kingdom, Morocco, Singapore, Hong Kong and Brazil would be realized as of February 23, 2018 . As a result of the Tax Act, we have the ability to repatriate the cash associated with foreign subsidiary earnings to our U.S. parent without incurring additional U.S. federal income tax, as these earnings were subject to U.S. federal income taxes in 2018. However, this cash may be subject to foreign withholding taxes and/or U.S. state and local taxes if repatriated to the U.S. We are currently evaluating the capital needs of our foreign operations to determine the amount of cash that can be repatriated to the U.S. with minimal additional tax cost. Until such time that we complete this analysis, we maintain our assertion of indefinite reinvestment in our foreign earnings. Pursuant to SAB 118, we have not made a provision for foreign withholding or U.S. state and local taxes on $139.5 of unremitted foreign earnings and profits as of February 23, 2018. Taxes Payable or Refundable Income taxes currently payable or refundable are reported on the Consolidated Balance Sheets as follows: Income Taxes February 23, February 24, Other current assets: Income taxes receivable $ 19.7 $ 19.0 Other long-term assets: Income taxes receivable $ — $ 18.5 Accrued expenses: Income taxes payable $ 8.6 $ 6.4 Net Operating Loss and Tax Credit Carryforwards Operating loss and tax credit carryforwards expire as follows: Fiscal Year Ending February Net Operating Loss Net Operating Loss Tax Credit Federal State International Federal State International Total 2019 $ — $ — $ 2.0 $ — $ — $ 0.6 $ 0.6 $ — 2023-2038 — 17.0 — — 1.9 — 1.9 31.8 No expiration — — 217.7 — — 53.3 53.3 — $ — $ 17.0 $ 219.7 — 1.9 53.9 55.8 31.8 Valuation allowances — (0.5 ) (7.3 ) (7.8 ) (1.7 ) Net benefit $ — $ 1.4 $ 46.6 $ 48.0 $ 30.1 Future tax benefits for net operating loss and tax credit carryforwards are recognized to the extent that realization of these benefits is considered more likely than not. It is considered more likely than not that a benefit of $78.1 will be realized on these net operating loss and tax credit carryforwards. This determination is based on the expectation that related operations will be sufficiently profitable or various tax, business and other planning strategies available to us will enable utilization of the carryforwards. We assess the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets. Valuation allowances are recorded to the extent realization of these carryovers is not more likely than not. Uncertain Tax Positions We are subject to taxation in the U.S. and various states and foreign jurisdictions with varying statutes of limitation. Tax years that remain subject to examination by major tax jurisdictions include: the U.S. 2018, Canada 2015 through 2018, France 2014 through 2018 and Germany 2014 through 2018. We adjust these reserves, as well as the related interest and penalties, in light of changing facts and circumstances. We are audited by the U.S. Internal Revenue Service under the Compliance Assurance Process (“CAP”). Under CAP, the U.S. Internal Revenue Service works with large business taxpayers to identify and resolve issues prior to the filing of a tax return. Accordingly, we record minimal liabilities for U.S. federal uncertain tax positions. We recognize interest and penalties associated with uncertain tax positions in income tax expense, and these items were insignificant for 2018 , 2017 and 2016 . As of February 23, 2018 and February 24, 2017 , the liability for uncertain tax positions, including interest and penalties, reported on the Consolidated Balance Sheets was as follows: Liability for Uncertain Tax Positions February 23, February 24, Other long-term liabilities $ — $ 0.2 A reconciliation of the beginning and ending balances of unrecognized tax benefits is as follows: Unrecognized Tax Benefits Year Ended February 23, February 24, February 26, Balance as of beginning of period $ 2.8 $ 8.6 $ 8.8 Gross decreases—tax positions in prior period (1.0 ) (5.3 ) — Currency translation adjustment 0.4 (0.5 ) (0.2 ) Balance as of end of period $ 2.2 $ 2.8 $ 8.6 We have taken tax positions in a non-U.S. jurisdiction that do not meet the more likely than not test required under the uncertain tax position accounting guidance. Of the gross decreases shown above, $0.8 relates to changes in the French statutory tax rate. Since the tax positions have increased net operating loss carryforwards, the underlying deferred tax asset is shown net of a $2.2 liability for uncertain tax positions. Unrecognized tax benefits of $2.2 , if favorably resolved, would be recorded as an income tax benefit. We do not expect the amount of unrecognized tax benefits will significantly change due to expiring statutes or audit activity in the next twelve months.

Share-based Compensation [Abstract]
Share-Based Compensation	SHARE-BASED COMPENSATION The Steelcase Inc. Incentive Compensation Plan (the “Incentive Compensation Plan”) provides for the issuance of share-based compensation awards to employees and members of our Board of Directors. There are 25,000,000 shares of Class A Common Stock reserved for issuance under our Incentive Compensation Plan, with 7,101,070 shares remaining for future issuance under our Incentive Compensation Plan as of February 23, 2018 . A variety of awards may be granted under the Incentive Compensation Plan, including stock options, stock appreciation rights (“SARs”), restricted stock, restricted stock units, performance shares, performance units, cash-based awards, phantom shares and other share-based awards. Outstanding awards under the Incentive Compensation Plan vest over a period of three years. Our Board of Directors may amend or terminate the Incentive Compensation Plan at its discretion subject to certain provisions as stipulated within the plan. For awards granted prior to July 15, 2015, in the event of a “change in control,” as defined in the Incentive Compensation Plan, • if at least six months have elapsed following the award date, any performance-based conditions imposed with respect to outstanding awards shall be deemed to be fully earned and a pro rata portion of each such outstanding award granted for all outstanding performance periods shall become payable in shares of Class A Common Stock; and • all restrictions imposed on restricted stock units that are not performance-based shall lapse. For awards granted after July 15, 2015, in the event of a "change in control", • performance-based conditions imposed on outstanding awards will be deemed to be, immediately prior to the change in control, the greater of (1) the applicable performance achieved through the date of the change in control or (2) the target level of performance; and • all restrictions imposed on all outstanding awards of restricted stock units and performance units will lapse if either (1) the awards are assumed by an acquirer or successor and the awardee experiences a qualifying termination during the two year period following the change in control or (2) the awards are not assumed by an acquirer or successor. Share-based awards currently outstanding under the Incentive Compensation Plan are as follows: Total Outstanding Awards February 23, Performance units (1) 688,600 Restricted stock units 1,789,775 Total outstanding awards 2,478,375 ________________________ (1) This amount includes the maximum number of shares that may be issued under outstanding performance unit awards; however, the actual number of shares which may be issued will be determined based on the satisfaction of certain criteria, and therefore may be significantly lower. Performance Units Performance units have been granted only to our executive officers. These awards are earned after a three-year performance period and only if the performance criteria stated in the applicable award are achieved. After completion of the performance period, the number of performance units earned will be issued as shares of Class A Common Stock. The aggregate number of shares of Class A Common Stock that ultimately may be issued under performance units where the performance period has not been completed ranged from 0 to 688,600 shares as of February 23, 2018 . The awards will be forfeited if a participant leaves the company for reasons other than retirement, disability or death or if the participant engages in any competition with us, as defined in the Incentive Compensation Plan and determined by the Administrative Committee in its discretion. A dividend equivalent is calculated based on the actual number of units earned at the end of the performance period equal to the dividends that would have been payable on the earned units had they been held during the entire performance period as Class A Common Stock. At the end of the performance period, the dividend equivalents are paid in the form of cash. All of the performance units granted in 2018 and 2017 and half of the performance units granted in 2016 can be earned based on achievement of certain total shareholder return results relative to a comparison group of companies ("TSR PSUs"), which is a market condition. The number of shares that may be earned under the TSR PSUs can range from 0% to 200% of the target amount. The TSR PSUs are expensed and recorded in Additional paid-in capital on the Consolidated Balance Sheets over the performance periods. Based on actual performance results, the TSR PSUs granted in 2016 were earned at 0.0% of the target level, and no shares of Class A Common Stock were issued to participants under such awards. The remaining half of the performance units granted in 2016 were earned based on our three-year average return on invested capital ("ROIC PSUs"), which is a performance condition. The number of shares that could be earned under the ROIC PSUs ranged from 0% to 200% of the target amount. The ROIC PSUs were expensed and recorded in Additional paid-in capital on the Consolidated Balance Sheets over the performance period based on the probability that the performance condition will be met. The expense recorded was adjusted as the estimate of the total number of ROIC PSUs that were expected to ultimately be earned changed. The weighted-average grant date fair value per share of ROIC PSUs granted in 2016 was $18.68 . The fair value is equal to the closing price of shares of our Class A Common Stock on the date of the grant. Based on actual performance results, the ROIC PSUs granted in 2016 were earned at 156.0% of the target level and 209,353 shares of Class A Common Stock were issued to participants in Q1 2019 . The fair values of the TSR PSUs were calculated on their respective grant dates using the Monte Carlo simulation model, which resulted in a fair value of $3.4 , $3.1 and $5.7 for the TSR PSUs granted in 2018 , 2017 and 2016 , respectively. The Monte Carlo simulation was computed using the following assumptions: 2018 Awards 2017 Awards 2016 Awards Three-year risk-free interest rate (1) 1.4 % 0.9 % 0.8 % Expected term 3 years 3 years 3 years Estimated volatility (2) 31.8 % 31.2 % 29.4 % ________________________ (1) Based on the U.S. Government bond benchmark on the grant date. (2) Represents the historical price volatility of our Company’s Class A Common Stock for the three-year period preceding the grant date. The Monte Carlo simulation resulted in the following weighted-average grant date fair values per TSR PSU: Grant Date Fair Value per TSR PSU Year Ended February 23, February 24, February 26, Weighted-average grant date fair value per share of TSR PSUs granted during 2018, 2017 and 2016 $ 21.76 $ 16.33 $ 24.15 The total performance units expense and associated tax benefit in 2018 , 2017 and 2016 was as follows: Performance Units Year Ended February 23, February 24, February 26, Expense $ 5.0 $ 5.6 $ 7.4 Tax benefit 1.7 2.0 2.7 The 2018 activity for performance units is as follows: Maximum Number of Nonvested Units Total Weighted-Average Grant Date Fair Value per Unit Nonvested as of February 24, 2017 916,420 $ 19.31 Granted 309,000 21.76 Vested (536,820 ) 21.42 Nonvested as of February 23, 2018 688,600 18.77 As of February 23, 2018 , there was $1.8 of remaining unrecognized compensation cost related to nonvested performance units. That cost is expected to be recognized over a remaining weighted-average period of 1.7 years. The total fair value of performance units vested following completion of the three-year performance periods during 2018 , 2017 and 2016 was $3.0 , $5.6 and $7.0 , respectively. The fair value was determined based upon the closing price of shares of our Class A Common Stock as of the date the Compensation Committee of our Board of Directors certified the awards. Restricted Stock Units Restricted stock units (“RSUs”) have restrictions on transfer which lapse three years after the date of grant, at which time RSUs are issued as unrestricted shares of Class A Common Stock. These awards will be forfeited if a participant leaves the company for reasons other than retirement, disability or death or if the participant engages in any competition with us, as defined in the Incentive Compensation Plan and determined by the Administrative Committee in its discretion. RSUs are expensed and recorded in Additional paid-in capital on the Consolidated Balance Sheets over the requisite service period based on the value of the shares on the grant date. The weighted-average grant date fair value per share of RSUs granted in 2018 , 2017 and 2016 is as follows: Grant Date Fair Value per Share Year Ended February 23, February 24, February 26, Weighted-average grant date fair value per share of RSUs granted $ 16.51 $ 14.66 $ 18.82 The total RSUs expense and associated tax benefit in 2018 , 2017 and 2016 is as follows: Restricted Stock Units Year Ended February 23, February 24, February 26, Expense $ 13.4 $ 13.5 $ 12.9 Tax benefit 4.5 4.9 4.6 Holders of RSUs receive cash dividends equal to the dividends we declare and pay on our Class A Common Stock, which are included in Dividends paid on the Consolidated Statements of Cash Flows. The 2018 activity for RSUs is as follows: Nonvested Units Total Weighted-Average Grant Date Fair Value per Share Nonvested as of February 24, 2017 1,731,507 $ 16.38 Granted 780,321 16.51 Vested (688,965 ) 18.17 Forfeited (33,088 ) 16.14 Nonvested as of February 23, 2018 1,789,775 15.75 There was $8.0 of remaining unrecognized compensation cost related to RSUs as of February 23, 2018 . That cost is expected to be recognized over a weighted-average period of 1.8 years. The total fair value of RSUs vested was $10.1 , $13.1 and $16.6 during 2018 , 2017 and 2016 , respectively. The fair value was determined based upon the closing price of shares of our Class A Common Stock on the dates the awards vested. Unrestricted Share Grants Under the Incentive Compensation Plan, unrestricted shares of our Class A Common Stock may be issued to members of our Board of Directors as compensation for director’s fees. We granted a total of 50,445 , 48,045 and 39,052 unrestricted shares at a weighted average grant date fair value per share of $14.98 , $15.20 and $18.24 during 2018 , 2017 and 2016 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Guarantees	COMMITMENTS We lease certain sales offices, showrooms, warehouses and equipment under non-cancelable operating leases that expire at various dates through 2029. Operating lease agreements generally contain renewal options that may be exercised at our discretion after the completion of the terms. During the normal course of business, we have entered into sale-leaseback arrangements for certain facilities. Accordingly, these leases are accounted for as operating leases, and the related gains from the sale of the properties are recorded as deferred gains and are amortized over the lease term. Total deferred gains are included as a component of Other long-term liabilities on the Consolidated Balance Sheets and amounted to $0.3 as of February 23, 2018 and $1.5 as of February 24, 2017 . Gross rent expense under all non-cancelable operating leases was $53.7 , $49.8 and $48.8 for 2018 , 2017 and 2016 , respectively. Sublease rental income was $4.4 , $4.0 and $5.2 for 2018 , 2017 and 2016 , respectively. Our estimated future minimum annual rental commitments and sublease rental income under non-cancelable operating leases as of February 23, 2018 are as follows: Fiscal Year Ending in February Minimum annual Minimum annual Minimum annual 2019 $ 48.5 $ (3.7 ) $ 44.8 2020 41.4 (3.7 ) 37.7 2021 31.1 (3.3 ) 27.8 2022 27.2 (3.3 ) 23.9 2023 20.1 (2.2 ) 17.9 Thereafter 38.8 (0.8 ) 38.0 $ 207.1 $ (17.0 ) $ 190.1

Business Combination Disclosure [Text Block]	ACQUISITIONS On December 26, 2017, we acquired AMQ Solutions ("AMQ"), a California-based provider of height-adjustable desking, benching and seating for workstations in the open plan, collaborative environments and training rooms. In addition, we acquired certain assets of an affiliated company, Tricom Vision Limited. The total purchase price for the acquisition was $69.9 , payable in cash, which was primarily funded by the liquidation of short-term investments. An additional $4.5 is payable to the sellers contingent upon certain performance obligations being met over a two year period. This acquisition is expected to strengthen our reach within the industry by broadening our portfolio at lower price points. The goodwill resulting from the acquisition consists largely of economies of scale expected from integrating AMQ into our existing dealer network. Tangible assets and liabilities were valued as of the acquisition date using a market analysis and intangible assets were valued using a discounted cash flow analysis, which represents a Level 3 measurement. We recorded $30.1 related to identifiable intangible assets, $31.2 to goodwill and approximately $13 related to working capital items such as accounts receivable, inventories and accounts payable. The entire amount recorded to goodwill is deductible for U.S. income tax purposes. Intangibles are principally related to dealer relationships which will be amortized over 11 years. AMQ is included as part of the Americas segment. The purchase price allocation for the AMQ acquisition was incomplete as of February 23, 2018. We are still evaluating certain working capital adjustments, as well as the reporting unit to which the goodwill resulting from the AMQ acquisition will be allocated for future impairment testing purposes. The following table summarizes the acquired identified intangible assets and the respective fair value and useful life of each asset at the date of acquisition: Other Intangible Assets February 23, 2018 Weighted Fair Value Trademarks 9.0 $ 1.3 Dealer relationships 11.0 25.5 Other 4.6 3.3 $ 30.1 The fair value of the acquired intangible assets will be amortized on a straight-line basis over the remaining useful life. The estimated amortization expense for the next five years is as follows: Fiscal Year Ending in February Amount 2019 3.2 2020 3.1 2021 3.0 2022 3.0 2023 3.0 $ 15.3

Summary of Significant Accoun31

Summary of Significant Accounting Policies Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Feb. 23, 2018
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The consolidated financial statements include the accounts of Steelcase Inc. and its subsidiaries. We consolidate entities in which we maintain a controlling interest. All material intercompany transactions and balances have been eliminated in consolidation. We also consolidate variable interest entities when appropriate. Investments in entities where our equity ownership falls between 20% and 50% , or where we otherwise have significant influence, are accounted for under the equity method of accounting. All other investments in unconsolidated affiliates are accounted for under the cost method of accounting. These investments are reported as Investments in unconsolidated affiliates on the Consolidated Balance Sheets, and income from equity method and cost method investments are reported in Other income, net on the Consolidated Statements of Income . See Note 11 for additional information.
Fiscal Period, Policy [Policy Text Block]	Fiscal Year Our fiscal year ends on the last Friday in February, with each fiscal quarter typically including 13 weeks. The fiscal years ended February 23, 2018 , February 24, 2017 and February 26, 2016 contained 52 weeks. Reference to a year relates to the fiscal year, ended in February of the year indicated, rather than the calendar year, unless indicated by a specific date. Additionally, Q1, Q2, Q3 and Q4 reference the first, second, third and fourth quarter, respectively, of the fiscal year indicated. All amounts are in millions, except share and per share data, data presented as a percentage or as otherwise indicated.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the amounts and disclosures in the consolidated financial statements and accompanying notes. Although these estimates are based on historical data and management’s knowledge of current events and actions we may undertake in the future, actual results may differ from these estimates under different assumptions or conditions.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency For most foreign operations, local currencies are considered the functional currencies. We translate assets and liabilities of these subsidiaries to their U.S. dollar equivalents at exchange rates in effect as of the balance sheet date. Translation adjustments are not included in determining net income but are recorded in Accumulated other comprehensive income (loss) on the Consolidated Balance Sheets unless and until a sale or a substantially complete liquidation of the net investment in the international subsidiary takes place. We translate Consolidated Statements of Income accounts at average exchange rates for the applicable period. Foreign currency transaction gains and losses, net of derivative impacts, arising primarily from changes in exchange rates on foreign currency denominated intercompany loans and other intercompany transactions and balances between foreign locations, are recorded in Other income, net on the Consolidated Statements of Income.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Cash and cash equivalents include demand bank deposits and highly liquid investment securities with an original maturity of three months or less. Cash equivalents are reported at cost and approximate fair value. Outstanding checks in excess of funds on deposit are classified as Accounts payable on the Consolidated Balance Sheets. Our restricted cash balance as of February 23, 2018 and February 24, 2017 was $2.5 , and consisted of funds held in escrow for potential future workers’ compensation claims. Our restricted cash balance is classified in Other assets on the Consolidated Balance Sheets.
Receivables, Policy [Policy Text Block]	Allowances for Credit Losses Allowances for credit losses related to accounts receivable and notes receivable are maintained at a level considered by management to be adequate to absorb an estimate of probable future losses existing at the balance sheet date. In estimating probable losses, we review accounts that are past due or in bankruptcy. We consider an accounts receivable or notes receivable balance past due when payment is not received within the stated terms. We review accounts that may have higher credit risk using information available about the debtor, such as financial statements, news reports and published credit ratings. We also use general information regarding industry trends, the economic environment and information gathered through our network of field-based employees. Using an estimate of current fair market value of any applicable collateral and other credit enhancements, such as third party guarantees, we arrive at an estimated loss for specific concerns and estimate an additional amount for the remainder of trade balances based on historical trends and other factors previously referenced. Receivable balances are written off when we determine the balance is uncollectible. Subsequent recoveries, if any, are credited to bad debt expense when received.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations of Credit Risk Our trade receivables are due from independent dealers as well as direct customers. We monitor and manage the credit risk associated with individual dealers and direct customers. 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 typically assume the credit risk. Whether from dealers or direct customers, our trade credit exposures are not concentrated with any particular entity.
Inventory, Policy [Policy Text Block]	Inventories Inventories are stated at the lower of cost or net realizable value. The Americas segment primarily uses the last in, first out (“LIFO”) method to value its inventories. The EMEA segment values inventories primarily using the first in, first out method. Businesses within the Other category primarily use the first in, first out or the average cost inventory valuation methods. See Note 7 for additional information.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant and Equipment Property, plant and equipment are stated at cost. Major improvements that materially extend the useful lives of the assets are capitalized. Expenditures for repairs and maintenance are charged to expense as incurred. Depreciation is provided using the straight-line method over the estimated useful lives of the assets. Long-lived assets such as property, plant and equipment are tested for impairment when conditions indicate that the carrying value may not be recoverable. We evaluate several conditions, including, but not limited to, the following: a significant decrease in the market price of an asset or an asset group; a significant adverse change in the extent or manner in which a long-lived asset is being used, including an extended period of idleness; and a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. We review the carrying value of our held and used long-lived assets utilizing estimates of future undiscounted cash flows. If the carrying value of a long-lived asset is considered impaired, an impairment charge is recorded for the amount by which the carrying value of the long-lived asset exceeds its estimated fair value. When assets are classified as “held for sale,” losses are recorded for the difference between the carrying amount of the property, plant and equipment and the estimated fair value less estimated selling costs. Assets are considered “held for sale” when it is expected that the asset is going to be sold within twelve months.
Lease, Policy [Policy Text Block] (Deprecated 2017-01-31)	Operating Leases Rent expense under operating leases is recorded on a straight-line basis over the lease term unless the lease contains an escalation clause which is not fixed and determinable. The lease term begins when we have the right to control the use of the leased property, which is typically before rent payments are due under the terms of the lease. If a lease has a fixed and determinable escalation clause, the difference between rent expense and rent paid is recorded as deferred rent. Rent expense under operating leases that do not have an escalation clause or where escalation is based on an inflation index is expensed over the lease term as it is payable. See Note 17 for additional information.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Other Intangible Assets Goodwill represents the difference between the purchase price and the related underlying tangible and identifiable intangible net asset fair values resulting from business acquisitions. Annually in Q4, or earlier if conditions indicate it is necessary, the carrying value of the reporting unit is compared to an estimate of its fair value. If the estimated fair value of the reporting unit is less than the carrying value, goodwill is impaired and is written down to its estimated fair value. Goodwill is assigned to and the fair value is tested at the reporting unit level. In 2018 and 2017, we evaluated goodwill and intangible assets using six reporting units: the Americas, Red Thread, EMEA, Asia Pacific, Designtex and PolyVision. See Note 10 for additional information. Other intangible assets subject to amortization consist primarily of proprietary technology, trademarks, customer relationships and non-compete agreements and are amortized over their estimated useful economic lives using the straight-line method. Other intangible assets not subject to amortization, consisting of certain trademarks, are accounted for and evaluated for potential impairment in a manner consistent with goodwill. See Note 10 for additional information.
Commitments and Contingencies, Policy [Policy Text Block]	Contingencies Loss contingencies are accrued if the loss is probable and the amount of the loss can be reasonably estimated. Legal costs associated with potential loss contingencies are expensed as incurred. We are involved in litigation from time to time in the ordinary course of our business. Based on known information, we do not believe we are party to any lawsuit or proceeding, individually and in the aggregate, that is likely to have a material adverse impact on the consolidated financial statements.
Self Insurance [Policy Text Block]	Self-Insurance We are self-insured for certain losses relating to domestic workers’ compensation, product liability and employee medical, dental, and short-term disability claims. We purchase insurance coverage to reduce our exposure to significant levels of certain of these claims. Self-insured losses are accrued based upon estimates of the aggregate liability for uninsured claims incurred as of the balance sheet date using current and historical claims experience and certain actuarial assumptions. These estimates are subject to uncertainty due to a variety of factors, including extended lag times in the reporting and resolution of claims, and trends or changes in claim settlement patterns, insurance industry practices and legal interpretations. As a result, actual costs could differ significantly from the estimated amounts. Adjustments to estimated reserves are recorded in the period in which the change in estimate occurs. Net Reserve for Estimated Domestic Workers' Compensation Claims Year Ended February 23, 2018 February 24, 2017 Assets: Long-term - Other assets $ 4.4 $ 4.0 Liabilities: Current - Accrued expenses - other 3.0 2.4 Long-term - Other long-term liabilities 12.9 13.9 15.9 16.3 Net reserve $ 11.5 $ 12.3 The other long-term asset balance represents the portion of claims expected to be paid by a third party insurance provider. Net Reserve for Estimated Product Liability Claims Year Ended February 23, 2018 February 24, 2017 Assets: Long-term - Other long-term assets $ 2.7 $ 2.4 Liabilities: Current - Accrued expenses - other 1.3 1.4 Long-term - Other long-term liabilities 6.7 7.3 8.0 8.7 Net reserve $ 5.3 $ 6.3 The other long-term asset balance represents the portion of claims expected to be paid by a third party insurance provider. The estimate for unpaid employee medical, dental, and short-term disability claims incurred as of February 23, 2018 and February 24, 2017 was $3.9 and $4.5 , respectively, and is recorded within Accrued expenses: Other on the Consolidated Balance Sheets.
Standard Product Warranty, Policy [Policy Text Block]	Product Warranties We offer warranties ranging from 3 years to lifetime for most products, subject to certain exceptions. These warranties provide for the free repair or replacement of any covered product, part or component that fails during normal use because of a defect in materials or workmanship. The accrued liability for product warranties is based on an estimated amount needed to cover product warranty costs, including product recall and retrofit costs, incurred as of the balance sheet date determined by historical claims experience and our knowledge of current events and actions. Roll-Forward of Accrued Year Ended February 23, February 24, February 26, Balance as of beginning of period $ 41.3 $ 42.1 $ 39.4 Accruals related to product warranties, recalls and retrofits 10.6 19.5 18.1 Reductions for settlements (15.8 ) (20.1 ) (16.0 ) Currency translation adjustments 0.7 (0.2 ) 0.6 Balance as of end of period $ 36.8 $ 41.3 $ 42.1 Our reserve for estimated settlements expected to be paid beyond one year as of February 23, 2018 and February 24, 2017 was $18.7 and $20.9 , respectively, and is included in Other long-term liabilities on the Consolidated Balance Sheets.
Pension and Other Postretirement Plans, Policy [Policy Text Block]	Pension and Other Post-Retirement Benefits We sponsor a number of domestic and foreign plans to provide pension benefits and medical and life insurance benefits to retired employees. We measure the net over-funded or under-funded positions of our defined benefit pension plans and post-retirement benefit plans as of the end of each fiscal year and display that position as an asset or liability on the Consolidated Balance Sheets. Any unrecognized prior service credit (cost) or experience gains (losses) are reported, net of tax, as a component of Accumulated other comprehensive income (loss) in shareholders’ equity. See Note 13 for additional information.
Environmental Costs, Policy [Policy Text Block]	Environmental Matters Environmental expenditures related to current operations are expensed or capitalized as appropriate. Expenditures related to an existing condition allegedly caused by past operations, and not associated with current or future revenue generation, are expensed. Generally, the timing of these accruals coincides with completion of a feasibility study or our commitment to a formal plan of action. Liabilities are recorded on a discounted basis as site-specific plans indicate the amount and timing of cash payments are fixed and reliably determinable. We have ongoing monitoring and identification processes to assess how known exposures are progressing against the accrued cost estimates, as well as processes to identify other potential exposures. Environmental Contingencies Year Ended February 23, 2018 February 24, 2017 Current: Accrued expenses - other $ 0.7 $ 0.6 Long-Term: Other long-term liabilities 2.5 3.3 Total environmental contingencies (discounted) $ 3.2 $ 3.9 The environmental liabilities were discounted using a rate of 3.5% and 4.0% as of February 23, 2018 and February 24, 2017 . Our undiscounted liabilities were $3.7 and $4.8 as of February 23, 2018 and February 24, 2017 , respectively. Based on our ongoing evaluation of these matters, we believe we have accrued sufficient reserves to absorb the costs of all known environmental assessments and the remediation costs of all known sites.
Asset Retirement Obligation [Policy Text Block]	Asset Retirement Obligations We record all known asset retirement obligations for which the liability’s fair value can be reasonably estimated. We also have known conditional asset retirement obligations that are not reasonably estimable due to insufficient information about the timing and method of settlement of the obligation. Accordingly, these obligations have not been recorded in the consolidated financial statements. A liability for these obligations will be recorded in the period when sufficient information regarding timing and method of settlement becomes available to make a reasonable estimate of the liability’s fair value. In addition, there may be conditional asset retirement obligations we have not yet discovered, and therefore, these obligations also have not been included in the consolidated financial statements.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition Revenue consists substantially of product sales and related service revenue. Product sales are reported net of discounts and are recognized when title and risks associated with ownership have passed to the dealer or customer. Under sales contracts with our dealers, this typically occurs when product is shipped. In cases where we have a direct sales contract with the customer, title and risks associated with ownership often transfer upon delivery or acceptance by the customer. Revenue from services is recognized when the services have been rendered. Revenue does not include sales tax, as we consider ourselves a pass-through entity for collecting and remitting sales taxes.
Cost of Sales, Policy [Policy Text Block]	Cost of Sales Cost of sales includes material, labor and overhead. Included within these categories are such items as compensation expense, logistics costs (including shipping and handling costs), facilities expense, depreciation and warranty expense.
Selling, General and Administrative Expenses, Policy [Policy Text Block]	Operating Expenses Operating expenses include selling, general and administrative expenses not directly related to the procurement, manufacturing and delivery of our products. Included in these expenses are items such as employee compensation expense, research and development expense, facilities expense, depreciation, royalty expense, information technology services, professional services and travel and entertainment expense.
Research and Development Expense, Policy [Policy Text Block]	Research and Development Expenses Research and development expenses, which we define as expenses related to the investigative activities we conduct to improve existing products and procedures or to lead to the development of new products and procedures, are expensed as incurred and were $44.0 for 2018 , $35.8 for 2017 and $33.0 for 2016 .
Income Tax, Policy [Policy Text Block]	Income Taxes Deferred income tax assets and liabilities are recognized for the estimated future tax consequences attributable to temporary differences between the consolidated financial statements carrying amounts of existing assets and liabilities and their respective tax bases. These deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which the temporary differences are expected to reverse. The effect of a change in tax rates on deferred income tax assets and liabilities is recognized in the Consolidated Statements of Income in the period that includes the enactment date. We establish valuation allowances against deferred tax assets when it is more likely than not that all or a portion of the deferred tax assets will not be realized. All evidence, both positive and negative, is identified and considered in making the determination. Future realization of the existing deferred tax asset depends, in part, on the existence of sufficient taxable income of appropriate character within the carryforward period available under tax law applicable in the jurisdiction in which the related deferred tax assets were generated. We have net operating loss carryforwards available in certain jurisdictions to reduce future taxable income. Future tax benefits associated with net operating loss carryforwards are recognized to the extent that realization of these benefits is considered more likely than not. This determination is based on the expectation that related operations will be sufficiently profitable or various tax, business and other planning strategies will enable us to utilize the net operating loss carryforwards. In making this determination we consider all available positive and negative evidence. To the extent that available evidence raises doubt about the realization of a deferred income tax asset, a valuation allowance is established. We record reserves for uncertain tax positions except to the extent it is more likely than not that the tax position will be sustained on audit, based on the technical merits of the position. Periodic changes in reserves for uncertain tax positions are reflected in the provision for income taxes. See Note 15 for additional information.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Share-Based Compensation Our share-based compensation consists of restricted stock units and performance units. Our policy is to expense share-based compensation using the fair-value based method of accounting for all awards granted, modified or settled. Restricted stock units and performance units are credited to shareholders' equity as they are expensed over the requisite service periods based on the grant date fair value of the shares expected to be issued. See Note 16 for additional information.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Financial Instruments The carrying amounts of our financial instruments, consisting of cash and cash equivalents, accounts and notes receivable, accounts and notes payable and certain other liabilities, approximate their fair value due to their relatively short maturities. Our short-term investments, foreign exchange forward contracts and long-term investments are measured at fair value on the Consolidated Balance Sheets. Our total debt is carried at cost and was $295.0 and $297.4 as of February 23, 2018 and February 24, 2017 , respectively. The fair value of our total debt is measured using a discounted cash flow analysis based on current market interest rates for similar types of instruments and was approximately $316 and $330 as of February 23, 2018 and February 24, 2017 , respectively. The estimation of the fair value of our total debt is based on Level 2 fair value measurements. See Note 6 and Note 12 for additional information. We periodically use derivative financial instruments to manage exposures to movements in interest rates and foreign exchange rates. The use of these financial instruments modifies the exposure of these risks with the intention to reduce our risk of short-term volatility. We do not use derivatives for speculative or trading purposes.
Derivatives, Policy [Policy Text Block]	Foreign Exchange Forward Contracts A portion of our revenue and earnings is exposed to changes in foreign exchange rates. We seek to manage our foreign exchange risk largely through operational means, including matching same currency revenue with same currency costs and same currency assets with same currency liabilities. Foreign exchange risk is also partially managed through the use of derivative instruments. Foreign exchange forward contracts serve to reduce the risk of conversion or translation of certain foreign denominated transactions, assets and liabilities. We primarily use derivatives for intercompany working capital loans and certain forecasted currency flows from foreign-denominated transactions. The foreign exchange forward contracts relate to the euro, the Mexican peso, the United Kingdom pound sterling, the Canadian dollar, the Australian dollar, the Malaysian ringgit and the Japanese yen. See Note 6 for additional information. Assets and liabilities related to derivative instruments as of February 23, 2018 and February 24, 2017 are summarized below: Consolidated Balance Sheets February 23, February 24, Other current assets $ 2.1 $ 3.5 Accrued expenses (1.4 ) (0.9 ) Total net fair value of derivative instruments (1) $ 0.7 $ 2.6 ________________________ (1) The notional amounts of the outstanding foreign exchange forward contracts were $95.7 as of February 23, 2018 and $101.2 as of February 24, 2017 .

The 2021 Notes were issued at 99.953% of par value. The bond discount of $0.1 and direct debt issuance costs of $3.0 were deferred and are being amortized over the life of the 2021 Notes. Although the coupon rate of the 2021 Notes is 6.375% , the effective interest rate is 6.6% after taking into account the impact of the direct debt issuance costs, a deferred loss on interest rate locks related to the debt issuance and the bond discount. The 2021 Notes rank equally with all of our other unsecured unsubordinated indebtedness, and they contain no financial covenants. We may redeem some or all of the 2021 Notes at any time. The redemption price would equal the greater of (1) the principal amount of the notes being redeemed; or (2) the present value of the remaining scheduled payments of principal and interest discounted to the redemption date on a semi-annual basis at the comparable U.S. Treasury rate plus 45 basis points; plus, in both cases, accrued and unpaid interest. If the notes are redeemed within 3 months of maturity, the redemption price would be equal to the principal amount of the notes being redeemed plus accrued and unpaid interest. Amortization expense related to the direct debt issuance costs and bond discount on the 2021 Notes was $0.3 in 2018 , 2017 and 2016 . (2) We have a $125 global committed five-year bank facility which has an interest rate of LIBOR plus an applicable margin and is set to expire in September 2021.

In addition, we have revolving credit agreements of $47.0 which can be utilized to support bank guarantees, letters of credit, overdrafts and foreign exchange contracts. As of February 23, 2018 , we had $14.8 in outstanding bank guarantees and standby letters of credit against these agreements. We had no draws against our standby letters of credit during 2018 . (3) We have a $45.4 note payable with an original amount of $50.0 at a floating interest rate based on 30-day LIBOR plus 1.20% . The loan has a term of seven years and requires fixed monthly principal payments of $0.2 on a 20-year amortization schedule with a $32 balloon payment due in 2024 . The loan is secured by two corporate aircraft, contains no financial covenants and is not cross-defaulted to our other debt facilities. (4) We have unsecured uncommitted short-term credit facilities of up to $2.6 of U.S. dollar obligations and up to $24.6 of foreign currency obligations with various financial institutions available for working capital purposes as of February 23, 2018 .

Those items that reversed in 2018 were remeasured using a tax rate of 32.9% . We have recorded a provisional decrease of $23.9 with respect to the Tax Act in 2018. As required by the Tax Act, we have recorded a provisional tax liability of $4.0 related to the U.S. federal income taxes on approximately $76.2 of undistributed earnings of our non-U.S. subsidiaries, net of $12.0 of related U.S. foreign tax credits. (2) The valuation allowance provisions were based on current year activity, and the valuation allowance adjustments were based on various factors, which are further detailed below. In Q4 2015, we implemented changes in EMEA to align our tax structure with the management of our globally integrated business. Our U.S. parent company became the principal in a contract manufacturing model with Steelcase European subsidiaries. In Q4 2016, we reached the conclusion that there was sufficient positive evidence, including acceptance of our new tax structure by the U.S. Internal Revenue Service, sustained profitability in our French subsidiaries and other factors, which caused us to reverse valuation allowances of $56.0 recorded against net deferred tax assets in France. (3) Investment tax credits were granted by the Czech Republic for investments in qualifying manufacturing equipment. (4) The increase in the cash surrender value of COLI policies, net of normal insurance expenses, plus death benefit gains are non-taxable. (5) The foreign operations, less applicable foreign tax credits, amounts include the rate differential between local statutory rates and the U.S. rate on foreign operations. (6) Reductions to the French corporate tax rate resulted in the revaluation of certain deferred tax assets of our French tax group, causing increases to income tax expense of $4.0 and $7.9 in 2018 and 2017, respectively. During 2017, reductions to the United Kingdom corporate tax rate increased tax expense by $1.5 . (7) Adjustments in 2017 related to a French income tax audit that was settled in 2017

[1]	The weighted-average interest rate for short-term borrowings and the current portion of long-term debt was 2.8% as of February 23, 2018 and 1.8% as of February 24, 2017
[2]	We have $250 of unsecured unsubordinated senior notes, due in February 2021 (“2021 Notes”). The 2021 Notes were issued at 99.953% of par value. The bond discount of $0.1 and direct debt issuance costs of $3.0 were deferred and are being amortized over the life of the 2021 Notes. Although the coupon rate of the 2021 Notes is 6.375%, the effective interest rate is 6.6% after taking into account the impact of the direct debt issuance costs, a deferred loss on interest rate locks related to the debt issuance and the bond discount. The 2021 Notes rank equally with all of our other unsecured unsubordinated indebtedness, and they contain no financial covenants. We may redeem some or all of the 2021 Notes at any time. The redemption price would equal the greater of (1) the principal amount of the notes being redeemed; or (2) the present value of the remaining scheduled payments of principal and interest discounted to the redemption date on a semi-annual basis at the comparable U.S. Treasury rate plus 45 basis points; plus, in both cases, accrued and unpaid interest. If the notes are redeemed within 3 months of maturity, the redemption price would be equal to the principal amount of the notes being redeemed plus accrued and unpaid interest. Amortization expense related to the direct debt issuance costs and bond discount on the 2021 Notes was $0.3 in 2018, 2017 and 2016
[3]	We have a $125 global committed five-year bank facility which has an interest rate of LIBOR plus an applicable margin and is set to expire in September 2021. As of February 23, 2018 and February 24, 2017, there were no borrowings outstanding under the facility, our availability was not limited, and we were in compliance with all covenants under the facility. In addition, we have revolving credit agreements of $47.0 which can be utilized to support bank guarantees, letters of credit, overdrafts and foreign exchange contracts. As of February 23, 2018, we had $14.8 in outstanding bank guarantees and standby letters of credit against these agreements. We had no draws against our standby letters of credit during 2018
[4]	We have unsecured uncommitted short-term credit facilities of up to $2.6 of U.S. dollar obligations and up to $24.6 of foreign currency obligations with various financial institutions available for working capital purposes as of February 23, 2018. Interest rates are variable and determined at the time of borrowing. These credit facilities have no stated expiration date but may be changed or canceled by the banks at any time. There were no borrowings on these facilities as of February 23, 2018 and February 24, 2017
[5]	We have a $45.4 note payable with an original amount of $50.0 at a floating interest rate based on 30-day LIBOR plus 1.20%. The loan has a term of seven years and requires fixed monthly principal payments of $0.2 on a 20-year amortization schedule with a $32 balloon payment due in 2024. The loan is secured by two corporate aircraft, contains no financial covenants and is not cross-defaulted to our other debt facilities.

Line of Credit Facility, Interest Rate Description		The greatest of the prime rate, the Federal fund effective rate plus 0.5%, and the Eurocurrency rate for a one month interest period plus 1%, plus the applicable margin as set forth in the credit agreement; or the Eurocurrency rate plus the applicable margin as set forth in the credit agreement.
Line of Credit Facility, Covenant Terms		A maximum leverage ratio covenant, which is measured by the ratio of (x) indebtedness (as determined under the credit agreement) less excess liquidity (as determined under the credit agreement) to (y) the trailing four quarter Adjusted EBITDA (as determined under the credit agreement) and is required to be no greater than 3:1. (In the context of certain permitted acquisitions, we have a one-time ability, subject to certain conditions, to increase the maximum ratio to 3.25 to 1.0 for four consecutive quarters). A minimum interest coverage ratio covenant, which is measured by the ratio of (y) trailing four quarter Adjusted EBITDA (as determined under the credit agreement) to (z) trailing four quarter interest expense and is required to be no less than 3.5:1. The facility requires us to comply with certain other covenants, including a restriction on the aggregate amount of cash dividend payments and share repurchases in any fiscal year. In general, as long as our leverage ratio is less than 2.50 to 1.0, there is no restriction on cash dividends and share repurchases. If our leverage ratio is between 2.50 to 1.0 and the maximum then permitted, our ability to pay more than $35.0 in cash dividends and share repurchases in aggregate in any fiscal year may be restricted, depending on our liquidity.

[1]	We have $250 of unsecured unsubordinated senior notes, due in February 2021 (“2021 Notes”). The 2021 Notes were issued at 99.953% of par value. The bond discount of $0.1 and direct debt issuance costs of $3.0 were deferred and are being amortized over the life of the 2021 Notes. Although the coupon rate of the 2021 Notes is 6.375%, the effective interest rate is 6.6% after taking into account the impact of the direct debt issuance costs, a deferred loss on interest rate locks related to the debt issuance and the bond discount. The 2021 Notes rank equally with all of our other unsecured unsubordinated indebtedness, and they contain no financial covenants. We may redeem some or all of the 2021 Notes at any time. The redemption price would equal the greater of (1) the principal amount of the notes being redeemed; or (2) the present value of the remaining scheduled payments of principal and interest discounted to the redemption date on a semi-annual basis at the comparable U.S. Treasury rate plus 45 basis points; plus, in both cases, accrued and unpaid interest. If the notes are redeemed within 3 months of maturity, the redemption price would be equal to the principal amount of the notes being redeemed plus accrued and unpaid interest. Amortization expense related to the direct debt issuance costs and bond discount on the 2021 Notes was $0.3 in 2018, 2017 and 2016
[2]	We have a $125 global committed five-year bank facility which has an interest rate of LIBOR plus an applicable margin and is set to expire in September 2021. As of February 23, 2018 and February 24, 2017, there were no borrowings outstanding under the facility, our availability was not limited, and we were in compliance with all covenants under the facility. In addition, we have revolving credit agreements of $47.0 which can be utilized to support bank guarantees, letters of credit, overdrafts and foreign exchange contracts. As of February 23, 2018, we had $14.8 in outstanding bank guarantees and standby letters of credit against these agreements. We had no draws against our standby letters of credit during 2018
[3]	We have unsecured uncommitted short-term credit facilities of up to $2.6 of U.S. dollar obligations and up to $24.6 of foreign currency obligations with various financial institutions available for working capital purposes as of February 23, 2018. Interest rates are variable and determined at the time of borrowing. These credit facilities have no stated expiration date but may be changed or canceled by the banks at any time. There were no borrowings on these facilities as of February 23, 2018 and February 24, 2017
[4]	We have a $45.4 note payable with an original amount of $50.0 at a floating interest rate based on 30-day LIBOR plus 1.20%. The loan has a term of seven years and requires fixed monthly principal payments of $0.2 on a 20-year amortization schedule with a $32 balloon payment due in 2024. The loan is secured by two corporate aircraft, contains no financial covenants and is not cross-defaulted to our other debt facilities.
