Accounting Policies [Abstract]
Significant accounting policies	2. Significant accounting policies Basis of consolidation and presentation The consolidated financial statements include the financial statements of the Company and its majority-owned subsidiaries. Subsidiaries are consolidated if the Company has a controlling financial interest, which may exist based on ownership of a majority of the voting interest, or based on the Company’s determination that it is the primary beneficiary of a variable interest entity (“VIE”). The Company does not have any material interests in VIEs. All intercompany balances and transactions are eliminated in consolidation. Unless otherwise indicated, all financial data presented in these consolidated financial statements are expressed in US dollars. On our consolidated statements of cash flows for 2018, the amounts included in “net proceeds under revolving credit facilities,” which were previously included in “proceeds from the issuance of long-term debt,” are now presented separately to conform to the current year presentation. Use of estimates The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions affecting the amounts reported and disclosed in the financial statements and accompanying notes. Actual results could differ materially from these estimates. Recently issued and adopted accounting pronouncements On January 1, 2020, the Company adopted ASU 2016-13 “Financial Instruments - Credit Losses” (Topic 326), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. The transition to the new methodology did not have a significant financial impact and the Company did not recognize a cumulative-effect adjustment to the opening balance of accumulated deficit. On January 1, 2020, the Company adopted ASU 2018-13 “Fair Value Measurement” (Topic 820), which modifies the disclosure requirements for fair value measurements by removing, modifying and adding certain disclosures. On January 1, 2020, the Company adopted ASU 2018-15 “Intangibles - Goodwill and Other - Internal-Use Software” (Subtopic 350-40), which aligns the requirements for capitalizing implementation costs incurred in a service contract hosting arrangement with those for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company adopted this guidance on a prospective basis. On December 31, 2020, the Company adopted ASU 2018-14 “Compensation - Retirement Benefits - Defined Benefit Plans - General” (Subtopic 715-20), which amends the disclosure requirements related to defined benefit pension and other postretirement plans. The adoption did not have a significant impact upon the Company's financial statements and disclosures. Accounting pronouncements issued but not yet adopted In December 2019, the FASB issued ASU 2019-12 “Income Taxes” (Topic 740) – “Simplifying the Accounting for Income Taxes.” The ASU clarifies and simplifies the accounting for income taxes by eliminating certain exceptions for intra-period tax allocation principles, updating the methodology for calculating income tax rates in an interim period and aligning the recognition of deferred taxes for outside basis differences in an investment, among other updates. The Company will adopt this guidance effective January 1, 2021 and does not expect it to have a material impact on our consolidated financial statements and disclosures. In March 2020, the FASB issued ASU 2020-04 “Reference Rate Reform” (Topic 848) – “Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides optional expedients and exceptions for applying US GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform from currently referenced rates, such as LIBOR, to alternative rates. The ASU is effective beginning March 12, 2020 and the Company may elect to apply the amendments prospectively through December 31, 2022. The Company has established a project team to evaluate contract exposure and optional practical expedients provided by the standard. The Company is currently determining the impacts of the guidance on our consolidated financial statements. Cash and cash equivalents Cash and cash equivalents include highly-liquid investments with an original maturity of three months or less that are readily convertible into known amounts of cash. Trade accounts receivable, net and allowance for doubtful accounts Trade accounts receivable are stated at the invoiced amount, net of an allowance for doubtful accounts. The allowance for doubtful accounts reflects the Company's current estimate of credit losses expected to be incurred over the life of the trade accounts receivable. Collectability of the trade accounts receivable balance is assessed on an ongoing basis and determined based on the delinquency of customer accounts, the financial condition of individual customers, past collections experience and future economic expectations. Changes in the allowance for doubtful accounts are as follows: (in millions) 2020 2019 2018 Balance as of January 1 $ 12.9 $ 11.2 $ 13.0 Provision for credit losses 9.3 5.1 4.7 Write-offs (4.4) (3.4) (4.9) Recoveries 0.1 0.4 — Dispositions (0.5) — — Other adjustments — — (0.4) Foreign exchange (0.2) (0.4) (1.2) Balance as of December 31 $ 17.2 $ 12.9 $ 11.2 Inventories Inventories consist primarily of products purchased for resale and are stated at the lower of cost or net realizable value. Inventory cost is determined based on the weighted average cost method and includes purchase price from producers net of rebates received, inbound freight and handling, and direct labor and other costs incurred to blend and repackage product, but excludes depreciation expense. Property, plant and equipment, net Property, plant and equipment are carried at historical cost, net of accumulated depreciation. Depreciation is recorded on a straight-line basis over the estimated useful life of each asset as follows: Buildings 10-50 years Main components of tank farms 5-40 years Containers 2-15 years Machinery and equipment 5-20 years Furniture, fixtures and others 5-20 years Information technology 3-10 years The Company evaluates the useful life and carrying value of property, plant and equipment for impairment if an event occurs or circumstances change that would indicate the carrying value may not be recoverable. If the carrying amount of the asset group is not recoverable on an undiscounted cash flow basis, an impairment loss is recognized to the extent that the asset group's carrying amount exceeds its estimated fair value. Goodwill and intangible assets Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in business combinations. Goodwill is tested for impairment annually on October 1, or between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company’s reporting units are USA, EMEA, Canada, Latin America and Asia-Pacific. For each of the reporting units, the Company has the option to perform either the qualitative or the quantitative test. In the event a reporting unit fails the qualitative assessment, it is required to perform the quantitative test. The quantitative impairment test considers both the income approach and the market approach to estimate a reporting unit’s fair value. Significant estimates include forecasted EBITDA, market segment growth rates, estimated costs, and discount rates based on a reporting unit's weighted average cost of capital. If the fair value of the reporting unit is less than its carrying value, the reporting unit will recognize an impairment for the lesser of either the amount by which the reporting unit's carrying amount exceeds the fair value of the reporting unit or the reporting unit’s goodwill carrying value. The Company's intangible assets have finite lives and are amortized over their respective useful lives of 2 to 20 years. Intangible assets are tested for impairment if an event occurs or circumstances change that indicates the carrying value may not be recoverable. Short-term financing Short-term financing includes bank overdrafts and short-term lines of credit. Income taxes Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using enacted tax rates and laws that are expected to be in effect when the differences reverse. Deferred tax assets are also recognized for the estimated future effects of tax loss carryforwards. The effect on deferred taxes of changes in tax rates is recognized in the period in which the revised tax rate is enacted. The Company records valuation allowances to reduce deferred tax assets to the extent it believes it is more likely than not that such assets will not be realized. In making such determinations, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, forecasted and appropriate character of future taxable income, tax planning strategies, our experience with operating loss and tax credit carryforwards not expiring unused, tax planning strategies and the ability to carry back losses to prior years. The Company is subject to the global intangible low tax income (“GILTI”), which is a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The Company treats taxes due on future US inclusions in taxable income related to GILTI as a current-period expense when incurred. The Company recognizes interest and penalties related to unrecognized tax benefits within interest expense and warehousing, selling and administrative, respectively, in the accompanying consolidated statements of operations. Accrued interest and penalties are included in other accrued expenses and other long-term liabilities in the consolidated balance sheets. Defined benefit plans The Company sponsors several defined benefit plans and recognizes actuarial gains or losses, known as “mark to market” adjustments, at the December 31 measurement date. The mark to market adjustments primarily include gains and losses resulting from changes in discount rates and the difference between the expected and actual rate of return on plan assets. Settlement gains and losses are recognized in the period in which the settlement occurs. The fair value of plan assets is used to calculate the expected return on assets component of the net periodic benefit cost. Leases At the commencement date of a lease, the Company recognizes a liability to make lease payments and an asset representing the right to use the underlying asset during the lease term. The lease liability is measured at the present value of lease payments over the lease term, including variable fees that are known or subject to a minimum floor. The lease liability includes lease component fees, while non-lease component fees are expensed as incurred for all asset classes. When a contract excludes an implicit rate, the Company utilizes an incremental borrowing rate based on information available at the lease commencement date including, lease term and geographic region. The initial valuation of the right-of-use (“ROU”) asset includes the initial measurement of the lease liability, lease payments made in advance of the lease commencement date and initial direct costs incurred by the Company and excludes lease incentives. Leases with an initial term of 12 months or less are classified as short-term leases and are not recorded on the consolidated balance sheets. The lease expense for short-term leases is recognized on a straight-line basis over the lease term. Legal costs We expense legal costs as incurred. Environmental liabilities Environmental liabilities are recognized for probable and reasonably estimable losses associated with environmental remediation. Incremental direct costs of the investigation, remediation effort and post-remediation monitoring are included in the estimated environmental liabilities. The Company discounts environmental liabilities if the liability and the respective payments streams are fixed or reliably determinable. Expected cash outflows related to environmental remediation for the next 12 months and amounts for which the timing is uncertain are reported as current within other accrued expenses in the consolidated balance sheets. The long-term portion of environmental liabilities is reported within other long-term liabilities in the consolidated balance sheets. Environmental remediation expenses are included within warehousing, selling and administrative expenses in the consolidated statements of operations, unless associated with disposed operations, in which case such expenses are included in other operating expenses, net. Revenue recognition Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring a good or providing a service. Since the term between invoicing and payment is less than a year, the Company has not recognized a significant financing component. Revenue for bill-and-hold arrangements is recognized if the Company has a substantive customer request, the materials are properly segregated and designated as belonging to the customer, materials are ready to be transferred to the customer and the Company is unable to direct the materials to service another customer. Chemical Distribution Revenue is recognized when performance obligations under the terms of the contract are satisfied, which generally occurs when goods are transferred to a customer under the terms of the sale. Net sales include product sales and billings for freight and handling charges, net of discounts, expected returns, customer price and volume incentives and sales or other revenue-based taxes. The Company estimates customer price and volume incentives and expected customer returns based on historical experience. Crop Sciences The Company generates revenue when control for products is transferred to customers. The amount of consideration recorded varies due to price movements and rights granted to customers to return product. Customer payment terms often extend through a growing season, which may be up to six months. Transaction prices may move during an agricultural growing season and are affected by special offers or volume discounts, which affect the amount of consideration the Company will receive. The Company estimates the expected returns and changes in the transaction price based on the combination of historical experience and the impact of weather on the current agriculture season. The adjustments to the transaction price and estimate of returns impacts revenues recognized. Services The Company generates revenue from services as they are performed and economic value is transferred to customers. Services provided to customers are primarily related to waste management services and warehousing services. Foreign currency translation Assets and liabilities of foreign subsidiaries are translated into US dollars at period-end exchange rates. Income and expense accounts of foreign subsidiaries are translated into US dollars at the average exchange rates for the period. The net exchange gains and losses arising on this translation are reflected as a component of currency translation within AOCI. Transaction gains and losses are recognized in other expense, net in the consolidated statements of operations. Transaction gains and losses relating to intercompany borrowings that are an investment in a foreign subsidiary are reflected as a component of currency translation within AOCI in stockholders’ equity. Stock-based compensation plans The Company measures the total amount of employee stock-based compensation expense based on the grant date fair value of each award. Expense is recognized for each separately vesting tranche on a straight-line basis over the requisite service period, which is the shorter of the service period of the award or the period until the employees' retirement eligibility date. The Company recognizes forfeitures when incurred. Fair value Certain assets and liabilities are required to be recorded at fair value. The estimated fair values of those assets and liabilities have been determined using market information and valuation methodologies. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. There are three levels of inputs that may be used to measure fair value: Level 1 Quoted prices for identical instruments in active markets. Level 2 Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuation in which all significant inputs and significant value drivers are observable in active markets. Level 3 Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable . Derivatives The Company uses derivative financial instruments to manage risks associated with foreign currency and interest rate fluctuations. We do not use derivative instruments for speculative trading purposes. The fair value of forward currency contracts is calculated by reference to current forward exchange rates for contracts with similar maturity profiles. The fair value of interest rate swaps is determined by estimating the net present value of amounts to be paid under the agreement offset by the net present value of the expected cash inflows based on market rates and associated yield curves. For derivative contracts with the same counterparty where the Company has a master netting arrangement with the counterparty, the fair value of the asset/liability is presented on a net basis within the consolidated balance sheets. Changes in the fair value of derivative financial instruments are recognized in the consolidated statements of operations within interest expense or other expense, net, unless specific hedge accounting criteria are met. Cash flows associated with derivative financial instruments are recognized in the operating section of the consolidated statements of cash flows. For derivatives designated as cash flow hedges, changes in the fair value of the derivative are recorded to AOCI and are reclassified to earnings when the underlying forecasted transaction affects earnings. For contracts designated as cash flow hedges, we reassess the probability of the underlying forecasted transactions occurring on a quarterly basis. For derivatives not designated as hedging instruments, all changes in fair value are recorded to earnings in the current period. Earnings per share Basic earnings per share is based on the weighted average number of common shares outstanding during each period. Diluted earnings per share is based on the weighted average number of common shares and dilutive common share equivalents outstanding during each period. The Company reflects common share equivalents relating to stock options, non-vested restricted stock and non-vested restricted stock units in its computation of diluted weighted average shares outstanding, unless the effect of inclusion is anti-dilutive. The effect of dilutive securities is calculated using the treasury stock method. We consider restricted stock awards to be participating securities, since holders of such shares have non-forfeitable dividend rights in the event the Company declares a common stock dividend.

Business Combinations [Abstract]
Business combinations	3. Business combinations Year ended December 31, 2020 Acquisition of Zhuhai Techi Chem Silicone Industry Corporation On December 18, 2020, the Company completed an acquisition of the specialty silicone solutions business of Zhuhai Techi Chem Silicone Industry Corporation (“Techi Chem”), a leading distributor of specialty silicone solutions used primarily for the coatings, adhesives, sealants, and elastomers (CASE) market within the China marketplace. The addition of Techi Chem will allow the Company to bring differential value to customers and suppliers within the CASE market. The purchase price of this acquisition was $6.8 million, composed of $4.6 million cash paid and a $2.2 million contingent consideration component. Refer to “Note 19: Fair value measurements” for further information on the contingent consideration liability. The purchase price allocation includes goodwill of $3.5 million, intangibles of $2.7 million, inventory of $1.0 million and other current assets and deferred tax liabilities of $(0.4) million. The goodwill is included in the LATAM segment and is primarily attributable to expected synergies. The Company does not expect the goodwill to be deductible for income tax purposes. The identified intangible assets relate to customer relationships which have a remaining weighted-average amortization period of eight years. The operating results subsequent to the acquisition date did not have a significant impact on the consolidated financial statements of the Company. The initial accounting for this acquisition has only been preliminarily determined, and is subject to valuations of intangible assets and inventory. Year ended December 31, 2019 Acquisition of Nexeo Solutions On February 28, 2019, the Company completed an acquisition of 100% of the equity interest of Nexeo Solutions, Inc., a leading global chemicals and plastics distributor. The acquisition expanded and strengthened Univar Solutions’ presence in North America and provides expanded opportunities to create the largest North American sales force in chemical and ingredients distribution and the broadest product offering. The total purchase price of the acquisition was $1,814.8 million, composed of $1,201.0 million of cash paid (net of cash acquired of $46.8 million) and $613.8 million of newly issued shares of Univar Solutions common stock, which represented approximately 26.4 million shares, based on Univar Solutions’ closing stock price of $23.29 on February 27, 2019. The final 26.4 million shares issued include the cancellation of 1.5 million shares in connection with the appraisal litigation settlement, see “Note 21: Commitments and contingencies” for more information. The cash portion of the purchase price, acquisition related costs and repayment of approximately $936.3 million of Nexeo’s debt and other long-term liabilities were funded using the proceeds from the issuance of Term B Loans, borrowings under the New Senior ABL Facility and the ABL Term Loan issued on February 28, 2019. Refer to “Note 18: Debt” for more information. As of March 31, 2020, the Company updated the purchase price allocation to reflect final deferred income tax adjustments, resulting in a $7.0 million increase to goodwill.

Refer to “Note 4: Discontinued operations and dispositions” for further information. The Company recorded $562.7 million of goodwill, consisting of $547.1 million in the USA segment, $3.8 million in Canada and $11.8 million in LATAM. The goodwill is primarily attributable to expected synergies from combining operations. The Company expects approximately $76.0 million of goodwill to be deductible for income tax purposes. The identified intangible assets were related to customer relationships which have a weighted-average amortization period of ten The Company assumed 50.0 million warrants, equivalent to 25.0 million Nexeo shares, with an estimated aggregate fair value of $26.0 million at the February 28, 2019 closing date. The warrants were converted into the right to receive, upon exercise, the merger consideration consisting of approximately 7.6 million shares of Univar Solutions common stock plus cash.

Dispositions On November 30, 2020, the Company completed the sale of its Canadian Agriculture services business for total net cash proceeds of $39.3 million after transaction-related expenses settled at closing, and subject to a final working capital adjustment. The Company recorded a $31.5 million pre-tax loss on sale of business in the condensed consolidated statements of operations. The sale of this business did not meet the criteria to be classified as a discontinued operation in the Company’s financial statements because the disposition did not represent a strategic shift that had, or will have, a major effect on the Company's operations and financial results. The following summarizes the income before income taxes attributable to this business through the date of the disposition: Year ended December 31, (in millions) 2020 2019 2018 Income before income taxes $ 2.8 $ 3.0 $ 4.4 On September 1, 2020, the Company completed the sale of its industrial spill and emergency response businesses to EnviroServe Inc. for total net cash proceeds of $6.2 million after transaction-related expenses and recorded a $9.3 million pre-tax loss on sale of business in the condensed consolidated statements of operations. In the fourth quarter of 2020, we recorded an estimated net working capital adjustment of $1.2 million, increasing the loss on sale recorded in the third quarter of 2020. The sale of these businesses did not meet the criteria to be classified as a discontinued operation in the Company’s financial statements because the dispositions did not represent a strategic shift that had, or will have, a major effect on the Company's operations and financial results.

Revenue from Contract with Customer [Abstract]
Revenue	5. Revenue The Company disaggregates revenues from contracts with customers by both geographic segments and revenue contract types. Geographic reportable segmentation is pertinent to understanding the Company's revenues, as it aligns to how the Company reviews the financial performance of its operations. Revenue contract types are differentiated by the type of good or service the Company offers customers, since the contractual terms necessary for revenue recognition are unique to each of the identified revenue contract types. The following tables disaggregate external customer net sales by major stream: USA EMEA Canada LATAM Consolidated (in millions) Year ended December 31, 2020 Chemical Distribution $ 4,698.1 $ 1,695.8 $ 749.7 $ 441.5 $ 7,585.1 Crop Sciences — — 315.1 — 315.1 Services 308.1 1.3 45.9 9.5 364.8 Total external customer net sales $ 5,006.2 $ 1,697.1 $ 1,110.7 $ 451.0 $ 8,265.0 USA EMEA Canada LATAM Consolidated (in millions) Year ended December 31, 2019 Chemical Distribution $ 5,507.2 $ 1,784.2 $ 852.8 $ 443.7 $ 8,587.9 Crop Sciences — — 318.0 — 318.0 Services 321.3 1.3 47.0 11.4 381.0 Total external customer net sales $ 5,828.5 $ 1,785.5 $ 1,217.8 $ 455.1 $ 9,286.9 USA EMEA Canada LATAM Consolidated (in millions) Year ended December 31, 2018 Chemical Distribution $ 4,775.2 $ 1,974.4 $ 877.6 $ 383.8 $ 8,011.0 Crop Sciences — — 381.6 — 381.6 Services 185.8 1.3 43.1 9.7 239.9 Total external customer net sales $ 4,961.0 $ 1,975.7 $ 1,302.3 $ 393.5 $ 8,632.5 Deferred revenue Deferred revenues are recognized as a contract liability when customers provide the Company with consideration prior to the Company satisfying a performance obligation and are recognized in revenue when the performance obligations are met. Deferred revenues relate to revenues that are expected to be recognized within one year and are recorded within the other accrued expenses line item of the consolidated balance sheet. Deferred revenues as of December 31, 2020 and 2019 were $5.8 million and $65.5 million, respectively. The decrease in deferred revenues is primarily related to the wind down of the Canadian Agriculture wholesale distribution business. Revenue recognized for the years ended December 31, 2020 and 2019 from amounts included in contract liabilities at the beginning of the period were $65.0 million and $44.5 million, respectively.

Restructuring and Related Activities [Abstract]
Restructuring charges	7. Restructuring charges Restructuring charges relate to the implementation of several regional strategic initiatives aimed at streamlining the Company’s cost structure and improving its operations. These actions primarily resulted in workforce reductions and other facility rationalization costs. Restructuring charges are recorded in other operating expenses, net in the consolidated statement of operations. 2020 Restructuring During the first quarter of 2020, management approved a plan to implement a new structure designed to streamline and accelerate the opportunities between Canada and USA operations resulting in a condensed and realigned reporting structure for the commercial, operating, human resources and finance functions. This change did not impact the Company's reportable segments. All restructuring actions under this program were complete as of June 30, 2020, except for final cash payments that will be made in the future. During the third and fourth quarters of 2020, the Company increased its previously disclosed estimate and recorded additional charges to earnings of $0.2 million and $0.1 million, respectively, within employee termination costs. During the second quarter of 2020, the Company initiated workforce reductions spanning across many job functions and locations in the USA and Other in order to align the Company's workforce with its anticipated business needs. All restructuring actions under this program were complete as of December 31, 2020, except for final cash payments that will be made in the future. As a result of both of these plans, we recorded the following charges: (in millions) Year ended December 31, 2020 Cumulative Costs Anticipated total costs USA: Employee termination costs $ 6.4 $ 6.4 $ 6.4 Canada: Employee termination costs $ 3.4 $ 3.4 $ 3.4 Other: Employee termination costs $ 0.8 $ 0.8 $ 0.8 Total $ 10.6 $ 10.6 $ 10.6 During the fourth quarter of 2020, the Company approved a plan to wind down its Canadian Agriculture wholesale distribution business as part of an in-depth review of the changing dynamics of the agriculture industry. The actions associated with this program were substantially complete as of December 31, 2020. As a result of this plan, we recorded the following charges: (in millions) Year ended December 31, 2020 Cumulative Costs Anticipated total costs Canada: Employee termination costs $ 1.7 $ 1.7 $ 1.8 Other exit costs 2.2 2.2 2.2 Total $ 3.9 $ 3.9 $ 4.0 2018 Restructuring During 2018, management approved a plan to consolidate departments. The actions associated with this program were substantially complete as of March 31, 2020, although cash payments will be made into the future. During 2020, the Company reduced its estimate, which was previously recorded as a charge to earnings, in the amount of $0.6 million within employee termination costs as a result of changes in organizational structure. The following table presents a summary of the financial impacts of that plan: (in millions) Year ended December 31, 2020 Cumulative costs Anticipated total costs USA: Employee termination costs $ (0.4) $ 5.1 $ 5.1 Other exit costs — 0.1 0.1 Total $ (0.4) $ 5.2 $ 5.2 Other: Employee termination costs $ (0.2) $ 1.0 $ 1.0 Total: Employee termination costs $ (0.6) $ 6.1 $ 6.1 Other exit costs — 0.1 0.1 Total $ (0.6) $ 6.2 $ 6.2 The following table summarizes activity related to accrued liabilities associated with restructuring: (in millions) January 1, 2020 Charge to earnings Cash paid Non-cash and other December 31, 2020 Employee termination costs $ 3.7 $ 11.7 $ (12.4) $ 0.2 $ 3.2 Facility exit costs 1.9 — (0.5) — 1.4 Other exit costs 0.2 2.2 — 0.1 2.5 Total $ 5.8 $ 13.9 $ (12.9) $ 0.3 $ 7.1 (in millions) January 1, 2019 Charge to earnings Cash paid December 31, 2019 Employee termination costs $ 4.2 $ 2.5 $ (3.0) $ 3.7 Facility exit costs 5.0 0.1 (3.2) 1.9 Other exit costs 0.2 — — 0.2 Total $ 9.4 $ 2.6 $ (6.2) $ 5.8 Restructuring liabilities of $6.6 million and $5.3 million were classified as current in other accrued expenses in the consolidated balance sheets as of December 31, 2020 and 2019, respectively. The long-term portion of restructuring liabilities of $0.5 million were recorded in other long-term liabilities in the consolidated balance sheets as of December 31, 2020 and 2019, and primarily consists of facility exit costs that are expected to be paid within the next five years.

Approximately $1.5 million of NOLs will expire in the period 2021 through 2027. The remaining $32.8 million has no expiration. Additionally, the Company has approximately $6.2 million of foreign tax credits and capital loss carryforwards. The Company does not expect future earnings of the appropriate character of taxable income which would allow it to utilize certain of these tax attributes in future tax years. Therefore, the Company will maintain a valuation allowance of $1.9 million on these amounts. Foreign Tax Effects The Company earns a significant amount of its operating income outside of the US. As of December 31, 2020, the Company is indefinitely reinvested with respect to its US directly-owned subsidiary earnings. Therefore, the Company has not recognized a deferred tax liability on its investment in foreign subsidiaries. The Company is subject to US income tax on substantially all foreign earnings under the GILTI provisions of the 2017 Tax Cut and Jobs Act, while a significant portion of remaining foreign earnings are eligible for the new dividends received deduction. As a result, a portion of any future repatriation of $391.2 million of undistributed earnings may be subject to US income tax, as well as state and local income taxes, and currency translation gains or losses. It is impracticable to calculate the exact amount. Additionally, gains and losses on any future taxable dispositions of US-owned foreign affiliates continue to be subject to US income tax. Tax Contingencies The changes in unrecognized tax benefits included in other long-term liabilities, excluding interest and penalties, are as follows: Year ended December 31, (in millions) 2020 2019 Balance as of January 1 $ 1.1 $ 0.4 Increase for tax positions of current year 16.4 — Increase for tax positions of prior years 17.8 — Increase for tax positions of prior years related to acquired business — 1.3 Reductions due to the statute of limitations expiration (0.3) (0.1) Foreign exchange — (0.5) Balance as of December 31 $ 35.0 $ 1.1 There were $35.0 million and $1.1 million of unrecognized tax benefits that if recognized would affect the annual effective tax rate at December 31, 2020 and 2019, respectively. The Company files income tax returns in the US and various state and foreign jurisdictions. Generally, tax years are open for review by taxing authorities for a period of three years. As of December 31, 2020, the Company has limited audit activity for tax years back to 2007 and 2008, as well as for the periods 2012 through 2019. The Company continues to believe its positions are supportable; however, due to uncertainties in any tax audit outcome, the Company’s estimates of the ultimate settlement of uncertain tax positions may change and the actual tax benefits may differ from the estimates. The Company recognized $0.6 million, $0.5 million and $0.1 million of interest and/or penalties related to income tax matters in interest expense related to unrecognized tax benefits in the consolidated statements of operations for the years ended December 31, 2020, 2019 and 2018, respectively. The Company had $1.9 million and $1.3 million of interest and penalties reflected within other long-term liabilities on the consolidated balance sheets as of December 31, 2020 and 2019, respectively.

The following summarizes pre-tax amounts included in AOCI at December 31, 2020 related to pension plan amendments: (in millions) Defined benefit pension plans Net prior service credit $ 23.8 Other postretirement benefit plan The Company previously maintained a health care plan for retired employees in the US. The obligation associated with this plan as of December 31, 2020 and 2019 was $1.6 million and $1.4 million, respectively. Actuarial assumptions Defined benefit pension plans The significant weighted average actuarial assumptions used in determining the benefit obligations and net periodic benefit cost (income) for the Company’s defined benefit plans are as follows: Domestic Foreign December 31, December 31, 2020 2019 2020 2019 Actuarial assumptions used to determine benefit obligations at end of period: Discount rate 2.55 % 3.28 % 1.55 % 2.14 % Expected annual rate of compensation increase N/A N/A 2.91 % 2.85 % Domestic Foreign Year ended December 31, Year ended December 31, 2020 2019 2018 2020 2019 2018 Actuarial assumptions used to determine net periodic benefit cost (income) for the period: Discount rate 3.28 % 4.47 % 3.87 % 2.14 % 2.92 % 2.61 % Expected rate of return on plan assets 6.50 % 6.75 % 6.75 % 2.75 % 3.83 % 4.43 % Expected annual rate of compensation increase N/A N/A N/A 2.85 % 2.85 % 2.87 % Discount rates are used to measure benefit obligations and the interest cost component of net periodic benefit cost (income). The Company selects its discount rates based on the consideration of equivalent yields on high-quality fixed income investments at each measurement date. Discount rates are based on a benefit cash flow-matching approach and represent the rates at which the Company’s benefit obligations could effectively be settled as of the measurement date. For domestic defined benefit plans, the discount rates are based on a hypothetical bond portfolio approach. The hypothetical bond portfolio is constructed to comprise AA-rated corporate bonds whose cash flow from coupons and maturities match the expected future plan benefit payments. The discount rate for the foreign defined benefit plans are based on a yield curve approach. For plans in countries with a sufficient corporate bond market, the expected future benefit payments are matched with a yield curve derived from AA-rated corporate bonds, subject to minimum amounts outstanding and meeting other selection criteria. For plans in countries without a sufficient corporate bond market, the yield curve is constructed based on prevailing government yields and an estimated credit spread to reflect a corporate risk premium. The expected long-term rate of return on plan assets reflects management’s expectations on long-term average rates of return on funds invested to provide for benefits included in the benefit obligations. The long-term rate of return assumptions are based on the outlook for equity and fixed income returns, with consideration of historical returns, asset allocations, investment strategies and premiums for active management when appropriate. Assumptions reflect the expected rates of return at the beginning of the year. Plan assets Plan assets for defined benefit plans are invested in global equity and debt securities through professional investment managers with the objective to achieve targeted risk adjusted returns and to maintain liquidity sufficient to fund current benefit payments. Each funded defined benefit plan has an investment policy that is administered by plan trustees with the objective of meeting targeted asset allocations based on the circumstances of that particular plan. The investment strategy followed by the Company varies by country depending on the circumstances of the underlying plan. Less mature plan benefit obligations are funded by using more equity securities as they are expected to achieve long-term growth while exceeding inflation. More mature plan benefit obligations are funded using a higher allocation of fixed income securities as they are expected to produce current income with limited volatility. The Company has adopted a dynamic investment strategy whereby as the plan funded status improves, the investment strategy is migrated to more liability matching assets, and return seeking assets are reduced. Risk management practices include the use of multiple asset classes for diversification purposes. Specific guidelines for each asset class and investment manager are implemented and monitored. The weighted average target asset allocation for defined benefit pension plans in the year ended December 31, 2020 is as follows: Domestic Foreign Asset category: Equity securities 50.0 % 15.0 % Debt securities 45.0 % 79.2 % Other 5.0 % 5.8 % Total 100.0 % 100.0 % Plan asset valuation methodologies are described below: Fair value methodology Description Cash This represents cash at banks at fair value. Investment funds Values are based on the net asset value of the units held at year end. The net asset values are based on the fair value of the underlying assets of the funds, minus their liabilities, and then divided by the number of units outstanding at the valuation date. The funds are traded on private markets that are not active; however, the unit price is based primarily on observable market data of the fund’s underlying assets. Insurance contracts The fair value is based on the present value of the accrued benefit. Domestic defined benefit plan assets The following summarizes the fair value of domestic plan assets by asset category and level within the fair value hierarchy: December 31, 2020 December 31, 2019 (in millions) Total Level 1 Level 2 Total Level 1 Level 2 Cash $ 2.7 $ 2.7 $ — $ 2.5 $ 2.5 $ — Investments funds (1) 539.1 — 539.1 492.7 — 492.7 Total $ 541.8 $ 2.7 $ 539.1 $ 495.2 $ 2.5 $ 492.7 (1) This category includes investments in 26.1% and 30.2% in US equities, 25.5% and 19.7% in non-US equities, 43.3% and 45.0% in US corporate bonds and 5.1% and 5.1% in other investments as of December 31, 2020 and 2019, respectively.

Multi-employer plans The Company contributes to several multi-employer pension plans based on obligations arising from collective bargaining agreements. The risks of participating in these multi-employer plans are different from single-employer plans in the following aspects: • Assets contributed to the multi-employer plan by the Company may be used to provide benefits to employees of other participating employers. • If the Company stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. Similarly, the Company could be liable for underfunded obligations of other, departed employers. • If the Company chooses to stop participating in some of its multi-employer plans, it may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability. A withdrawal liability will be recorded when it is probable that a liability exists and can be reasonably estimated. The Company’s participation in these plans for the annual period ended December 31, 2020 is outlined in the table below. The Pension Protection Act (PPA) zone status is the most recently available and is certified by the plan's actuary. Among other factors, plans in the “red zone” are less than 65 percent funded, plans in the “yellow zone” are less than 80 percent funded and plans in the “green zone” are at least 80 percent funded. The "FIP/RP status pending/implemented" column indicates plans for which a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented. In addition to regular plan contributions, the Company may be subject to a surcharge if the plan is in the red zone. The "Surcharge imposed" column indicates whether a surcharge has been imposed on contributions to the plan. The last column lists the expiration date(s) of the collective bargaining agreement(s) (CBA) to which the plans are subject. There are no minimum contributions required for future periods by the collective-bargaining agreements, statutory obligations or other contractual obligations. If the Company were to cease making contributions to these plans at one or more or all locations, it could trigger a withdrawal liability that could be material to the Company’s results of operations and cash flows. Calculating any such withdrawal liability depends on a number of factors that are out of the Company’s control and subject to change. Withdrawal liability represents an employer’s proportional share of the multi-employer plan’s unfunded vested benefits (“UVBs”). UVBs equal the value of non-forfeitable benefits owed by the plan, less the value of the plan’s assets. The value of assets and liabilities are determined using actuarial assumptions that reflect the actuary’s best estimate of anticipated UVBs for that employer. A significant portion of our exposure resides with our eight facilities in the Central States Pension Fund. Based on the most recent available information, Company estimates suggest that under certain circumstances the Company’s withdrawal liability in relation to the Central States multi-employer pension plan could be between $30 million to $60 million. Other estimates of possible outcomes incorporating additional external factors could result in materially higher withdrawal liabilities, though the Company believes that those outcomes are unlikely to occur based on available information. A withdrawal liability would generally be paid over a 20 year period. Over time, as additional information becomes available, the Company expects to make adjustments to these estimates as appropriate.

Stock-based compensation	12. Stock-based compensation In May 2020, the Company replaced and succeeded the Univar Inc. 2017 Omnibus Equity Incentive Plan (the “2017 Plan”) with the Univar Solutions Inc. 2020 Omnibus Incentive Plan (the “2020 Plan”). The 2017 Plan had no further awards granted and any available reserves under the 2017 Plan were terminated and not transferred to the 2020 Plan. There were no changes to the outstanding awards related to the 2017 Plan, the Univar Inc. 2015 Stock Incentive Plan and Univar Inc. 2011 Stock Incentive Plan (together with the 2017 Plan and the 2020 Plan, the “Plans”). The 2020 Plan allows the Company to issue awards to employees, consultants, and directors of the Company and its subsidiaries. Awards may be made in the form of stock options, stock purchase rights, restricted stock, restricted stock units, performance shares, performance units, stock appreciation rights, dividend equivalents, deferred share units or other stock-based awards. As of December 31, 2020, there were 12.4 million shares authorized under the Plans. For the years ended December 31, 2020, 2019 and 2018, the Company recognized total stock-based compensation expense within other operating expenses, net of $14.5 million, $25.1 million and $20.7 million, and a net tax (benefit) expense relating to stock-based compensation expense of $(2.0) million, $(2.4) million and $(2.6) million, respectively. Stock options Stock options expire ten years after the grant date and generally become exercisable over a four-year period or less, based on continued employment, with annual vesting. The exercise price of a stock option is determined based upon the fair value of the common stock at the time of each grant. Participants have no stockholder rights until the time of exercise. The Company will issue new shares upon exercise of stock options granted under the Plans. The following reflects stock option activity under the Plans: Number of stock options Weighted-average exercise price Weighted-average remaining contractual term (in years) Aggregate intrinsic value (in millions) Outstanding at January 1, 2020 3,690,625 $ 23.77 Granted 1,344,130 22.94 Exercised (63,353) 17.62 Forfeited (716,749) 22.63 Outstanding at December 31, 2020 4,254,653 $ 23.79 Exercisable at December 31, 2020 2,223,545 $ 24.51 4.1 $ 0.4 Expected to vest after December 31, 2020 2,031,108 $ 23.01 8.6 $ (8.1) As of December 31, 2020, the Company has unrecognized stock-based compensation expense related to non-vested stock options of approximately $3.9 million, which will be recognized over a weighted-average period of 0.9 years.

The grant date fair value of restricted stock is based on the market price of the common stock on that date. Non-vested shares of restricted stock may not be sold or transferred and are subject to forfeiture until vesting. Both vested and non-vested shares of restricted stock are included in the Company’s shares outstanding. Dividend equivalents are available for non-vested shares of restricted stock if dividends are declared by the Company during the vesting period. The following table reflects restricted stock activity under the Plans: Number of restricted stock Weighted average grant-date fair value Non-vested at January 1, 2020 28,120 $ 21.34 Granted 43,135 13.91 Vested (28,120) 21.34 Forfeited — — Non-vested at December 31, 2020 43,135 $ 13.91 As of December 31, 2020, the Company has unrecognized stock-based compensation expense related to non-vested restricted stock awards of approximately $0.2 million, which will be recognized over a weighted-average period of 0.4 years. The weighted-average grant-date fair value of restricted stock was $21.34 and $28.50 in 2019 and 2018, respectively. Restricted stock units (RSUs) RSUs awarded to employees generally vest in three four The following table reflects RSUs activity under the Plans: Number of Restricted Stock Unit Weighted-average grant-date fair value Non-vested at January 1, 2020 1,089,418 $ 23.67 Granted 600,217 21.29 Vested (405,588) 24.15 Forfeited (256,899) 23.21 Non-vested at December 31, 2020 1,027,148 $ 22.22 As of December 31, 2020, the Company has unrecognized stock-based compensation expense related to non-vested RSUs awards of approximately $7.6 million, which will be recognized over a weighted-average period of 1.0 years. Performance-based restricted stock units (PRSUs) The Company awards performance based shares to certain employees. These awards vest upon the passage of time and the achievement of performance criteria. For grants with Company based performance criteria, the vesting period is over three years with some shares vesting over each annual period. We review progress toward the attainment of the performance criteria each quarter during the vesting period. When it is probable the minimum performance criteria for the award will be achieved, we begin recognizing the expense equal to the proportionate share of the total fair value. The total expense recognized over the duration of performance awards will equal the date of grant multiplied by the number of shares ultimately awarded based on the level of attainment of the performance criteria. For grants with market performance criteria, the fair value is determined on the grant date and is calculated using the same inputs for expected volatility, and risk-free rate as stock options, with a duration of two years. The total expense recognized over the duration of the award will equal the fair value, regardless if the market performance criteria is met. The following table reflects PRSUs activity under the Plans: Number of Performance-Based Restricted Stock Unit Weighted-average grant-date fair value Non-vested at January 1, 2020 519,828 $ 24.77 Granted 251,195 23.41 Vested (103,836) 27.10 Forfeited (134,305) 24.81 Non-vested at December 31, 2020 532,882 $ 23.66 As of December 31, 2020, the Company has unrecognized stock-based compensation expense related to non-vested PRSUs awards of approximately $1.4 million, which will be recognized over a weighted-average period of 1.8 years. Fair value Year ended December 31, (in millions) 2020 2019 2018 Fair value of restricted stock, RSUs and PRSUs vested $ 9.2 $ 8.6 $ 11.8 Employee stock purchase plan The Univar Solutions Inc. Employee Stock Purchase Plan, or ESPP, authorizing the issuances of up to 2.0 million shares of the Company’s common stock allows qualified participants to purchase the Company’s common stock at 95% of its market price during the last day of two offering periods in each calendar year. The first offering period is January through June, and the second from July through December. As of December 31, 2020, the total number of shares issued under the plan for the two offering periods in 2020 was 88,623 shares. Stock-based compensation fair value assumptions The fair value of the Company’s stock that is factored into the fair value of stock options and utilized for restricted stock, RSUs and PRSUs with internally developed performance conditions is based on the grant date closing price on the New York Stock Exchange. The Black-Scholes-Merton option valuation model was used to calculate the fair value of stock options. The weighted average grant-date fair value of stock options was $6.17, $6.31 and $8.69 for the years ended December 31, 2020, 2019 and 2018, respectively. The weighted-average assumptions used under the Black-Scholes-Merton option valuation model were as follows: Year ended December 31, 2020 2019 2018 Risk-free interest rate (1) 1.4 % 2.6 % 2.7 % Expected dividend yield — — — Expected volatility (2) 24.4 % 23.7 % 23.2 % Expected term (years) (3) 6.0 6.0 6.0 (1) The risk-free interest rate is based on the US Treasury yield for a term consistent with the expected term of the stock options at the time of grant. (2) As the Company does not have sufficient historical volatility data, the expected volatility is based on the average historical data of a peer group of public companies over a period equal to the expected term of the stock options. (3) As the Company does not have sufficient historical exercise data under the Plans, the expected term is based on the average of the vesting period of each tranche and the original contract term of 10 years.

Asset Impairment Charges [Abstract]
Impairment Charges	16. Impairment charges Year ended December 31, 2020 During the second quarter of 2020, the Company determined there was a more likely than not expectation that the industrial spill and emergency response businesses within the USA segment would be sold. The Company determined this to be an impairment triggering event, requiring the assessment of the recoverability of these long-lived asset groups. The Company tested the recoverability and determined the assets to be impaired. As a result, the Company recorded a non-cash, pretax impairment charge of $15.5 million, consisting of $12.8 million of intangible assets, net and $2.7 million of property, plant and equipment, net within the consolidated statement of operations during the year ended December 31, 2020. During the third quarter of 2020, the Company decided to cease further investment in, and seek to restructure or exit a contract related to, certain technology assets, consisting of capitalized software and hardware components. This event represented an impairment triggering event requiring an impairment analysis within the Other segment. As a result of the analysis, the Company recorded a non-cash, pretax impairment charge of $19.7 million relating to property, plant and equipment, net within the consolidated statement of operations. During the fourth quarter of 2020, the Company incurred incremental costs under the terms of the contract that were not deemed recoverable and recorded an additional impairment charge of $2.0 million relating to property, plant and equipment within the consolidated statement of operations. No additional costs will be incurred under the contract as the Company finalized the terms of the exit in January 2021. Additionally, the Company recorded charges during 2020 in connection with the announced closure of certain production facilities in the USA segment and the wind down of its Canadian Agriculture wholesale distribution business. The events resulted in impairment charges related to property, plant and equipment, net of $3.0 million within the consolidated statement of operations during the year ended December 31, 2020. Year ended December 31, 2019 During the third quarter of 2019, the Company announced closure of certain production facilities in USA. The Company determined that these decisions indicated a triggering event, requiring the assessment of recoverability of these long-lived assets. Testing the assets for recoverability involves developing estimates of future cash flows directly associated with, and that are expected to arise as a direct result of, the use and eventual disposition of the assets. As the inputs for testing recoverability are largely based on management’s judgments and are not generally observable in active markets, the Company considers such measurements to be Level 3 measurements in the fair value hierarchy. The Company tested the recoverability of its long-lived assets and determined the carrying amount of the assets exceeded the sum of the expected undiscounted future cash flows. As a result, the Company recorded a non-cash, pretax impairment charge of $7.0 million related to property, plant and equipment within its consolidated statements of operations during the year ended December 31, 2019.

Senior Term Loan Facilities In the first quarter of 2019 to finance the acquisition of Nexeo, the Company entered into the Fourth Amendment to its credit agreement, dated July 1, 2015, which provided a new Term B-4 Loan facility in an aggregate principal amount of $300.0 million (“Term B-4 Loan”) and a new Euro Term B-2 Loan facility in an aggregate principal amount of €425.0 million (“EUR Term B-2 Loan”). In the second quarter of 2019, using the proceeds from the sale of Nexeo Plastics, the Company repaid a portion of its outstanding EUR Term B-2, Term B-3 and Term B-4 Loans. As a result of the prepayment, no mandatory principal payments are required until 2024 for the Term B-3 Loan. In the fourth quarter of 2019, the Company repaid in full the remaining Term B-4 Loan and entered into the Fifth Amendment which provided a new Term B-5 Loan facility in an aggregate principal amount of $400.0 million that matures on July 1, 2026 (“Term B-5 Loan”). The proceeds from the new Term B-5 loan were used to repay in full the remaining EUR Term B-2 Loan. The Term B-5 Loan is payable in quarterly installments of 0.25% of the aggregate initial principal amount. The interest rate applicable to the Term Loan B-5 is based on, at the borrower’s option, (i) a fluctuating rate of interest determined by reference to a base rate plus an applicable margin equal to 1.00% or (ii) a Eurocurrency rate plus an applicable margin equal to 2.00%. The Company can repay the Term B-5 Loan in whole or part without penalty. As a result of the Fifth Amendment of the Term B-5 Loan and the repayment of the Term B-4 Loan, the Company recognized a loss on extinguishment of debt of $9.4 million during the year ended December 31, 2019. In the first quarter of 2020, using the proceeds from the sale of the Environmental Sciences business, the Company repaid $174.0 million of the Term B-3 Loan. As a result of the prepayment, the Company recognized a loss on extinguishment of debt of $1.8 million during the year ended December 31, 2020. ABL Facilities In 2019, the Company amended and restated its July 28, 2015 ABL credit facility. The 2019 amendment, which matures on February 28, 2024, provides a five year senior secured ABL credit facility in an aggregate amount of $1.2 billion and $325.0 million, for the US and Canadian revolving commitments (“North American ABL Facility”), respectively, and a three year $175.0 million aggregate secured Canadian dollar ABL term loan facility (“ABL Term Loan”) (collectively, the “New Senior ABL Facility”). Borrowing availability is determined by a borrowing base consisting of eligible inventory and eligible accounts receivable. The interest rate on the ABL Term Loan is on a quarterly adjusted rate of interest determined by reference to either a prime or BA rate, at our option, plus an applicable margin. For the US and Canadian revolving loans, the adjusted interest rate is a base or eurocurrency rate plus an applicable margin. The ABL Term Loan is payable in quarterly installments beginning June 30, 2020 with a final maturity on February 28, 2022. However, due to an optional prepayment in 2019, the loan is expected to be fully paid by December 31, 2021. As a result of the 2019 amendment related to the New Senior ABL Facility, the Company recognized a loss on extinguishment of debt of $0.7 million during the year ended December 31, 2019. Senior Unsecured Notes During 2019, the Company issued $500.0 million in Senior Unsecured Notes, due December 1, 2027 (“2027 Senior Notes”), with a fixed interest rate of 5.125%. The net proceeds were used to repay all $399.5 million principal outstanding under the 6.75% Notes due 2023 and a portion of the debt outstanding under the North American ABL Facility. The Company can prepay the 2027 Senior Notes in whole or part at a premium on or after December 1, 2022 and without a premium on or after December 1, 2024. As a result of this transaction, we recorded a loss on extinguishment of debt of $9.7 million during the year ended December 31, 2019. Borrowing availability and assets pledged as collateral Availability of our credit facilities is determined based upon available qualifying collateral, as defined in the North American ABL Facility and Euro ABL Facility credit agreement. Unused line fees are as follows: December 31, 2020 2019 $1.525 billion North American ABL Facility 0.300 % 0.300 % €200 million Euro ABL Facility 0.375 % 0.375 % The North American ABL Facility is secured by a first priority lien of accounts receivable and inventories of our US and Canadian operating subsidiaries. In addition, 65% of the shares of certain foreign subsidiaries have been pledged as security. The Senior Term Loan Facilities are secured by substantially all of the assets of the US operating and management subsidiaries and are secured by a second priority lien on such accounts receivable and inventory. The Euro ABL Facility is primarily secured by accounts receivable and inventories of the Company’s subsidiaries in Belgium, France, the Netherlands, and United Kingdom. Assets pledged are as follows: December 31, (in millions) 2020 2019 Cash $ 91.5 $ 230.8 Trade accounts receivable, net 1,069.8 981.4 Inventories 547.4 668.8 Prepaid expenses and other current assets 222.9 206.3 Property, plant and equipment, net 864.3 956.1 Total $ 2,795.9 $ 3,043.4 Debt covenants The Company is in compliance with all debt covenants. The North American ABL Facility and ABL Term Loan are subject to comply with a minimum fixed charge coverage ratio. As of December 31, 2020 and 2019, we exceeded the minimum ratio and therefore the financial covenant remains inapplicable. Other Information The fair values of debt were based on current market quotes for similar borrowings and credit risk adjusted for liquidity, margins, and amortization, as necessary and are classified as level 2 in the fair value hierarchy. December 31, 2020 December 31, 2019 (in millions) Carrying amount Fair value Carrying amount Fair value Fair value of debt $ 2,640.6 $ 2,687.4 $ 2,713.8 $ 2,770.7 The Company is exposed to credit loss and loss of liquidity availability if the financial institutions or counterparties issuing us debt securities fail to perform. We minimize exposure to these credit risks by dealing with a diversified group of investment grade financial institutions. We manage credit risk by monitoring the credit ratings and market indicators of credit risk of our lending counterparties. We do not anticipate any non-performance by any of the counterparties.

Derivatives Foreign currency derivatives The Company uses forward currency contracts to hedge earnings from the effects of foreign exchange relating to certain of the Company’s intercompany and third-party receivables and payables denominated in a foreign currency. These derivative instruments are not formally designated as hedges by the Company and the terms of these instruments range from one to three months. Interest rate swaps The objective of the designated interest rate swap contracts is to offset the variability of cash flows in LIBOR indexed debt interest payments attributable to changes in the aforementioned benchmark interest rate related to the Term B-3 Loan and a portion of debt outstanding under the North American ABL Facility. The swaps have maturities at various dates through June 2024. On December 17, 2019, the Company terminated $750.0 million of the 2017 swaps resulting in a $1.1 million gain. As the hedge was considered to be effective and the forecasted transaction was considered probable of occurring, part of the gain remained in accumulated other comprehensive loss and will be amortized as a reduction to interest expense over the term of the forecasted Term B Loan. On March 17, 2020, the Company executed $250.0 million of interest rate swap contracts effective June 30, 2020 to replace swaps with maturities on June 30, 2020. Cross currency swap contracts Cross currency swap contracts are used to effectively convert the Term B-5 Loan’s principal amount of floating rate US dollar denominated debt of $400.0 million, including interest payments, to fixed-rate Euro denominated debt maturing in November 2024. As of December 31, 2020, approximately 95% of the cross currency swaps are designated as a cash flow hedge. The Company uses both undesignated interest rate swap contracts and cross currency swaps to manage interest rate variability and mitigate foreign exchange exposure.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	21. Commitments and contingencies Litigation In the ordinary course of business the Company is subject to pending or threatened claims, lawsuits, regulatory matters and administrative proceedings from time to time. Where appropriate the Company has recorded provisions in the consolidated financial statements for these matters. The liabilities for injuries to persons or property are in some instances covered by liability insurance, subject to various deductibles and self-insured retentions. The Company is not aware of any claims, lawsuits, regulatory matters or administrative proceedings, pending or threatened, that are likely to have a material effect on its overall financial position, results of operations, or cash flows. However, the Company cannot predict the outcome of any present or future claims or litigation or the potential for future claims or litigation and adverse developments could negatively impact earnings or cash flows in a particular future period. The Company is subject to liabilities from claims alleging personal injury from exposure to asbestos. The claims result primarily from an indemnification obligation related to Univar Solutions USA Inc.’s (“Univar”) 1986 purchase of McKesson Chemical Company from McKesson Corporation (“McKesson”). Once certain conditions have been met, Univar will have the ability to pursue insurance coverage, if any, that may be available under McKesson's historical insurance coverage to offset the impact of any fees, settlements, or judgments that Univar is obligated to pay because of its obligation to defend and indemnify McKesson. As of December 31, 2020, there were approximately 190 asbestos-related cases for which Univar has the obligation to defend and indemnify; however, this number tends to fluctuate up and down over time. Historically, the vast majority of these asbestos cases have been dismissed without payment or with a nominal payment. While the Company is unable to predict the outcome of these matters, it does not believe, based upon currently available facts, that the ultimate resolution of any of these matters will have a material effect on its overall financial position, results of operations, or cash flows. Unclaimed Property Audit The Company and its subsidiaries are the subject of an unclaimed property audit request issued by the State of Delaware. The State of Delaware retained a contingent-fee private audit firm to conduct the audit. In October 2018, the State of Delaware issued a subpoena to the Company requesting a broad swath of records and information purportedly necessary to perform the audit (the “Subpoena”). After receiving the Subpoena, the Company objected and also initiated a lawsuit in the Federal District Court for the District of Delaware challenging the constitutionality of the Subpoena and other provisions of Delaware's escheats law, which case is ongoing (the “Lawsuit”). In response to the Lawsuit, the State of Delaware filed a competing enforcement action in the Delaware Court of Chancery in order to compel the Company to comply with the Subpoena. The Lawsuit has been stayed pending the resolution of the enforcement action. In October 2020, the Delaware Court of Chancery deemed the Subpoena enforceable, subject to some limitations, but stayed enforcement of the Subpoena until the Company’s claims in the Lawsuit are resolved by the District Court. The Company intends to vigorously defend itself and believes it has strong defenses. The timing and outcome of these proceedings or any unclaimed property audits that may be subsequently conducted as a result of the outcome of the proceedings cannot be predicted with certainty at this time. Environmental The Company is subject to various federal, state and local environmental laws and regulations that require environmental assessment or remediation efforts (collectively “environmental remediation work”) and from time to time becomes aware of compliance matters regarding possible or alleged violations of these laws or regulations. For example, over the years, the Company has been identified as a “potentially responsible party” (“PRP”) under the Comprehensive Environmental Response, Compensation and Liability Act and/or similar state laws that impose liability for costs relating to environmental remediation work at various sites. As a PRP, the Company may be required to pay a share of the costs of investigation and cleanup of certain sites. The Company is currently engaged in environmental remediation work at approximately 125 locations, some that are now or were previously Company-owned/occupied and some that were never Company-owned/occupied (“non-owned sites”). The Company’s environmental remediation work at some sites is being conducted pursuant to governmental proceedings or investigations. At other sites, the Company, with appropriate state or federal agency oversight and approval, is conducting the environmental remediation work voluntarily. The Company is currently undergoing remediation efforts or is in the process of active review of the need for potential remediation efforts at approximately 104 current or formerly Company-owned/occupied sites. In addition, the Company may be liable as a PRP for a share of the clean-up of approximately 21 non-owned sites. These non-owned sites are typically (a) locations of independent waste disposal or recycling operations with alleged or confirmed contaminated soil and/or groundwater to which the Company may have shipped waste products or drums for re-conditioning, or (b) contaminated non-owned sites near historical sites owned or operated by the Company or its predecessors from which contamination is alleged to have arisen. In determining the appropriate level of environmental reserves, the Company considers several factors such as information obtained from investigatory studies; changes in the scope of remediation; the interpretation, application and enforcement of laws and regulations; changes in the costs of remediation programs; the development of alternative cleanup technologies and methods; and the relative level of the Company’s involvement at various sites for which the Company is allegedly associated. The level of annual expenditures for remedial, monitoring and investigatory activities will change in the future as major components of planned remediation activities are completed and the scope, timing and costs of existing activities are changed. Project lives, and therefore cash flows, range from 2 to 30 years, depending on the specific site and type of remediation project. Although the Company believes that its reserves are adequate for environmental contingencies, it is possible, due to the uncertainties noted above; that additional reserves could be required in the future that could have a material effect on the overall financial position, results of operations, or cash flows in a particular period. Changes in total environmental liabilities are as follows: (in millions) 2020 2019 Environmental liabilities as of January 1 $ 78.7 $ 83.5 Revised obligation estimates 16.7 13.3 Environmental payments (16.1) (18.0) Foreign exchange 0.3 (0.1) Environmental liabilities as of December 31 $ 79.6 $ 78.7 December 31, (in millions) Balance Sheet Classification 2020 2019 Current environmental liabilities Other accrued expenses $ 26.5 $ 25.0 Long-term environmental liabilities Other long-term liabilities 53.1 53.7 As of December 31, 2020, the total discount on environmental liabilities was nil. As of December 31, 2019, the total discount on environmental liabilities was $5.5 million and the discount rate used in the present value calculation was 1.9%, which represents the risk-free rate. The Company manages estimated cash flows by project. These estimates are subject to change if there are modifications to the scope of the remediation plan or if other factors, both external and internal, change the timing of the remediation activities. The Company periodically reviews the status of all existing or potential environmental liabilities and adjusts its accruals based on all available, relevant information. Based on current estimates, the expected payments for environmental remediation for the next five years and thereafter at December 31, 2020 are as follows, with projects for which timing is uncertain estimated at $10.8 million included within the 2021 estimated amount below: (in millions) 2021 $ 26.5 2022 13.5 2023 9.2 2024 7.5 2025 6.3 Thereafter 16.6 Total $ 79.6 Tax Matters During 2017, the Brazilian Federal Supreme Court (the “Court”) ruled that the inclusion of the state VAT tax collected by a taxpayer in the taxpayer’s federal social contribution calculation base is unconstitutional. In 2019, the Court ruled in the Company's favor allowing the recoverability of amounts previously paid, plus interest. As a result, the Company recorded a benefit of $10.9 million in net sales, of which $9.7 million related to prior years, and $4.6 million in interest income in the consolidated statements of operations for the year ended December 31, 2019. During the second quarter of 2020, the Company reduced its benefit from the prior year and recorded a charge of $0.4 million in net sales and $0.3 million in interest income in the consolidated statements of operations for the year ended December 31, 2020.

Segment Reporting [Abstract]
Segments	23. Segments Management monitors the operating results of its reportable segments separately for the purpose of making decisions about resource allocation and performance assessment. Management evaluates performance on the basis of Adjusted EBITDA. Adjusted EBITDA is defined as consolidated net (loss) income, plus the sum of: interest expense, net of interest income; income tax expense (benefit); depreciation; amortization; other operating expenses, net (see “Note 6: Other operating expenses, net” for more information); impairment charges; loss on extinguishment of debt; and other expense, net (see “Note 8: Other expense, net” for more information). For 2020, Adjusted EBITDA also includes an adjustment to remove a Brazil VAT charge. For 2019, Adjusted EBITDA also includes an adjustment to remove the charge of the inventory fair value step-up recorded in connection with the Nexeo purchase price allocation and to remove the benefit related to a Brazil VAT recovery. Transfer prices between reportable segments are set on an arms-length basis in a similar manner to transactions with third parties. Corporate operating expenses that directly benefit segments have been allocated to the reportable segments. Allocable operating expenses are identified through a review process by management. These costs are allocated to the reportable segments on a basis that reasonably approximates the use of services. This is typically measured on a weighted distribution of margin, asset, headcount or time spent. Financial information for the Company’s reportable segments is as follows: USA EMEA Canada LATAM Other/ Eliminations (1) Consolidated (in millions) Year ended December 31, 2020 External customers $ 5,006.2 $ 1,697.1 $ 1,110.7 $ 451.0 $ — $ 8,265.0 Inter-segment 81.2 3.1 2.5 — (86.8) — Total net sales $ 5,087.4 $ 1,700.2 $ 1,113.2 $ 451.0 $ (86.8) $ 8,265.0 Adjusted EBITDA $ 393.2 $ 142.7 $ 89.7 $ 43.0 $ (32.8) $ 635.8 Long-lived assets (2) $ 815.6 $ 202.0 $ 148.0 $ 38.0 $ 23.1 $ 1,226.7 USA EMEA Canada LATAM Other/ Eliminations (1) Consolidated (in millions) Year ended December 31, 2019 External customers $ 5,828.5 $ 1,785.5 $ 1,217.8 $ 455.1 $ — $ 9,286.9 Inter-segment 100.2 3.3 6.2 — (109.7) — Total net sales $ 5,928.7 $ 1,788.8 $ 1,224.0 $ 455.1 $ (109.7) $ 9,286.9 Adjusted EBITDA $ 454.7 $ 143.3 $ 100.2 $ 36.1 $ (30.1) $ 704.2 Long-lived assets (2) $ 853.6 $ 185.4 $ 197.3 $ 34.7 $ 38.7 $ 1,309.7 USA EMEA Canada LATAM Other/ Eliminations (1) Consolidated (in millions) Year ended December 31, 2018 External customers $ 4,961.0 $ 1,975.7 $ 1,302.3 $ 393.5 $ — $ 8,632.5 Inter-segment 126.6 4.0 9.3 0.2 (140.1) — Total net sales $ 5,087.6 $ 1,979.7 $ 1,311.6 $ 393.7 $ (140.1) $ 8,632.5 Adjusted EBITDA $ 376.4 $ 151.2 $ 104.7 $ 33.3 $ (25.2) $ 640.4 Long-lived assets (2) $ 597.6 $ 156.7 $ 141.3 $ 30.2 $ 30.0 $ 955.8 (1) Other/Eliminations represents the elimination of intersegment transactions as well as unallocated corporate costs consisting of costs specifically related to parent company operations that do not directly benefit segments, either individually or collectively.

Subsequent Events [Abstract]
Subsequent Events	25. Subsequent events On January 22, 2021, the Company entered into an agreement to sell its Distrupol business within the EMEA segment. The Company expects to recognize a pre-tax gain upon the sale of approximately $80 million within the consolidated statements of operations upon closing. The completion of the sale is subject to customary closing conditions and is expected to close in the first quarter of 2021. Subsequent to December 31, 2020, the Company expects to recognize a partial withdrawal liability of approximately $19.2 million for four locations that have or will soon exit the Central States multi-employer pension plan. The withdrawal liability represents the Company's best estimate based on the most recent available information, and does not reflect an assessment from the fund. The Company expects to pay this withdrawal liability over a 20-year period and to record any further adjustments that may be necessary in the period during which the withdrawal liability is confirmed or as additional information becomes available.

Accounting Policies [Abstract]
Basis of consolidation and presentation	Basis of consolidation and presentation The consolidated financial statements include the financial statements of the Company and its majority-owned subsidiaries. Subsidiaries are consolidated if the Company has a controlling financial interest, which may exist based on ownership of a majority of the voting interest, or based on the Company’s determination that it is the primary beneficiary of a variable interest entity (“VIE”). The Company does not have any material interests in VIEs. All intercompany balances and transactions are eliminated in consolidation. Unless otherwise indicated, all financial data presented in these consolidated financial statements are expressed in US dollars.
Use of estimates	Use of estimates The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions affecting the amounts reported and disclosed in the financial statements and accompanying notes. Actual results could differ materially from these estimates.
Recently issued and adopted accounting pronouncements and Accounting pronouncements issued but not yet adopted	Recently issued and adopted accounting pronouncements On January 1, 2020, the Company adopted ASU 2016-13 “Financial Instruments - Credit Losses” (Topic 326), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. The transition to the new methodology did not have a significant financial impact and the Company did not recognize a cumulative-effect adjustment to the opening balance of accumulated deficit. On January 1, 2020, the Company adopted ASU 2018-13 “Fair Value Measurement” (Topic 820), which modifies the disclosure requirements for fair value measurements by removing, modifying and adding certain disclosures. On January 1, 2020, the Company adopted ASU 2018-15 “Intangibles - Goodwill and Other - Internal-Use Software” (Subtopic 350-40), which aligns the requirements for capitalizing implementation costs incurred in a service contract hosting arrangement with those for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company adopted this guidance on a prospective basis. On December 31, 2020, the Company adopted ASU 2018-14 “Compensation - Retirement Benefits - Defined Benefit Plans - General” (Subtopic 715-20), which amends the disclosure requirements related to defined benefit pension and other postretirement plans. The adoption did not have a significant impact upon the Company's financial statements and disclosures. Accounting pronouncements issued but not yet adopted In December 2019, the FASB issued ASU 2019-12 “Income Taxes” (Topic 740) – “Simplifying the Accounting for Income Taxes.” The ASU clarifies and simplifies the accounting for income taxes by eliminating certain exceptions for intra-period tax allocation principles, updating the methodology for calculating income tax rates in an interim period and aligning the recognition of deferred taxes for outside basis differences in an investment, among other updates. The Company will adopt this guidance effective January 1, 2021 and does not expect it to have a material impact on our consolidated financial statements and disclosures. In March 2020, the FASB issued ASU 2020-04 “Reference Rate Reform” (Topic 848) – “Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides optional expedients and exceptions for applying US GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform from currently referenced rates, such as LIBOR, to alternative rates. The ASU is effective beginning March 12, 2020 and the Company may elect to apply the amendments prospectively through December 31, 2022. The Company has established a project team to evaluate contract exposure and optional practical expedients provided by the standard. The Company is currently determining the impacts of the guidance on our consolidated financial statements.
Cash and cash equivalents	Cash and cash equivalentsCash and cash equivalents include highly-liquid investments with an original maturity of three months or less that are readily convertible into known amounts of cash.
Trade accounts receivable, net	Trade accounts receivable, net and allowance for doubtful accounts Trade accounts receivable are stated at the invoiced amount, net of an allowance for doubtful accounts. The allowance for doubtful accounts reflects the Company's current estimate of credit losses expected to be incurred over the life of the trade accounts receivable. Collectability of the trade accounts receivable balance is assessed on an ongoing basis and determined based on the delinquency of customer accounts, the financial condition of individual customers, past collections experience and future economic expectations. Changes in the allowance for doubtful accounts are as follows: (in millions) 2020 2019 2018 Balance as of January 1 $ 12.9 $ 11.2 $ 13.0 Provision for credit losses 9.3 5.1 4.7 Write-offs (4.4) (3.4) (4.9) Recoveries 0.1 0.4 — Dispositions (0.5) — — Other adjustments — — (0.4) Foreign exchange (0.2) (0.4) (1.2) Balance as of December 31 $ 17.2 $ 12.9 $ 11.2
Inventories	InventoriesInventories consist primarily of products purchased for resale and are stated at the lower of cost or net realizable value. Inventory cost is determined based on the weighted average cost method and includes purchase price from producers net of rebates received, inbound freight and handling, and direct labor and other costs incurred to blend and repackage product, but excludes depreciation expense.
Property, plant and equipment, net	Property, plant and equipment, net Property, plant and equipment are carried at historical cost, net of accumulated depreciation. Depreciation is recorded on a straight-line basis over the estimated useful life of each asset as follows: Buildings 10-50 years Main components of tank farms 5-40 years Containers 2-15 years Machinery and equipment 5-20 years Furniture, fixtures and others 5-20 years Information technology 3-10 years The Company evaluates the useful life and carrying value of property, plant and equipment for impairment if an event occurs or circumstances change that would indicate the carrying value may not be recoverable. If the carrying amount of the asset group is not recoverable on an undiscounted cash flow basis, an impairment loss is recognized to the extent that the asset group's carrying amount exceeds its estimated fair value.
Goodwill and intangible assets	Goodwill and intangible assets Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in business combinations. Goodwill is tested for impairment annually on October 1, or between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company’s reporting units are USA, EMEA, Canada, Latin America and Asia-Pacific. For each of the reporting units, the Company has the option to perform either the qualitative or the quantitative test. In the event a reporting unit fails the qualitative assessment, it is required to perform the quantitative test. The quantitative impairment test considers both the income approach and the market approach to estimate a reporting unit’s fair value. Significant estimates include forecasted EBITDA, market segment growth rates, estimated costs, and discount rates based on a reporting unit's weighted average cost of capital. If the fair value of the reporting unit is less than its carrying value, the reporting unit will recognize an impairment for the lesser of either the amount by which the reporting unit's carrying amount exceeds the fair value of the reporting unit or the reporting unit’s goodwill carrying value.
Short-term financing and Long-term debt	Short-term financingShort-term financing includes bank overdrafts and short-term lines of credit.
Income taxes	Income taxes Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using enacted tax rates and laws that are expected to be in effect when the differences reverse. Deferred tax assets are also recognized for the estimated future effects of tax loss carryforwards. The effect on deferred taxes of changes in tax rates is recognized in the period in which the revised tax rate is enacted. The Company records valuation allowances to reduce deferred tax assets to the extent it believes it is more likely than not that such assets will not be realized. In making such determinations, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, forecasted and appropriate character of future taxable income, tax planning strategies, our experience with operating loss and tax credit carryforwards not expiring unused, tax planning strategies and the ability to carry back losses to prior years. The Company is subject to the global intangible low tax income (“GILTI”), which is a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The Company treats taxes due on future US inclusions in taxable income related to GILTI as a current-period expense when incurred. The Company recognizes interest and penalties related to unrecognized tax benefits within interest expense and warehousing, selling and administrative, respectively, in the accompanying consolidated statements of operations. Accrued interest and penalties are included in other accrued expenses and other long-term liabilities in the consolidated balance sheets.
Defined benefit plans	Defined benefit plans The Company sponsors several defined benefit plans and recognizes actuarial gains or losses, known as “mark to market” adjustments, at the December 31 measurement date. The mark to market adjustments primarily include gains and losses resulting from changes in discount rates and the difference between the expected and actual rate of return on plan assets. Settlement gains and losses are recognized in the period in which the settlement occurs. The fair value of plan assets is used to calculate the expected return on assets component of the net periodic benefit cost.
Leases	Leases At the commencement date of a lease, the Company recognizes a liability to make lease payments and an asset representing the right to use the underlying asset during the lease term. The lease liability is measured at the present value of lease payments over the lease term, including variable fees that are known or subject to a minimum floor. The lease liability includes lease component fees, while non-lease component fees are expensed as incurred for all asset classes. When a contract excludes an implicit rate, the Company utilizes an incremental borrowing rate based on information available at the lease commencement date including, lease term and geographic region. The initial valuation of the right-of-use (“ROU”) asset includes the initial measurement of the lease liability, lease payments made in advance of the lease commencement date and initial direct costs incurred by the Company and excludes lease incentives.
Legal costs	Legal costsWe expense legal costs as incurred.
Environmental liabilities	Environmental liabilities Environmental liabilities are recognized for probable and reasonably estimable losses associated with environmental remediation. Incremental direct costs of the investigation, remediation effort and post-remediation monitoring are included in the estimated environmental liabilities. The Company discounts environmental liabilities if the liability and the respective payments streams are fixed or reliably determinable. Expected cash outflows related to environmental remediation for the next 12 months and amounts for which the timing is uncertain are reported as current within other accrued expenses in the consolidated balance sheets. The long-term portion of environmental liabilities is reported within other long-term liabilities in the consolidated balance sheets. Environmental remediation expenses are included within warehousing, selling and administrative expenses in the consolidated statements of operations, unless associated with disposed operations, in which case such expenses are included in other operating expenses, net.
Revenue recognition	Revenue recognition Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring a good or providing a service. Since the term between invoicing and payment is less than a year, the Company has not recognized a significant financing component. Revenue for bill-and-hold arrangements is recognized if the Company has a substantive customer request, the materials are properly segregated and designated as belonging to the customer, materials are ready to be transferred to the customer and the Company is unable to direct the materials to service another customer. Chemical Distribution Revenue is recognized when performance obligations under the terms of the contract are satisfied, which generally occurs when goods are transferred to a customer under the terms of the sale. Net sales include product sales and billings for freight and handling charges, net of discounts, expected returns, customer price and volume incentives and sales or other revenue-based taxes. The Company estimates customer price and volume incentives and expected customer returns based on historical experience. Crop Sciences The Company generates revenue when control for products is transferred to customers. The amount of consideration recorded varies due to price movements and rights granted to customers to return product. Customer payment terms often extend through a growing season, which may be up to six months. Transaction prices may move during an agricultural growing season and are affected by special offers or volume discounts, which affect the amount of consideration the Company will receive. The Company estimates the expected returns and changes in the transaction price based on the combination of historical experience and the impact of weather on the current agriculture season. The adjustments to the transaction price and estimate of returns impacts revenues recognized. Services
Foreign currency translation	Foreign currency translation Assets and liabilities of foreign subsidiaries are translated into US dollars at period-end exchange rates. Income and expense accounts of foreign subsidiaries are translated into US dollars at the average exchange rates for the period. The net exchange gains and losses arising on this translation are reflected as a component of currency translation within AOCI.
Stock-based compensation plans	Stock-based compensation plansThe Company measures the total amount of employee stock-based compensation expense based on the grant date fair value of each award. Expense is recognized for each separately vesting tranche on a straight-line basis over the requisite service period, which is the shorter of the service period of the award or the period until the employees' retirement eligibility date. The Company recognizes forfeitures when incurred.
Fair value	Fair value Certain assets and liabilities are required to be recorded at fair value. The estimated fair values of those assets and liabilities have been determined using market information and valuation methodologies. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. There are three levels of inputs that may be used to measure fair value: Level 1 Quoted prices for identical instruments in active markets. Level 2 Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuation in which all significant inputs and significant value drivers are observable in active markets. Level 3 Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable .
Derivatives	Derivatives The Company uses derivative financial instruments to manage risks associated with foreign currency and interest rate fluctuations. We do not use derivative instruments for speculative trading purposes. The fair value of forward currency contracts is calculated by reference to current forward exchange rates for contracts with similar maturity profiles. The fair value of interest rate swaps is determined by estimating the net present value of amounts to be paid under the agreement offset by the net present value of the expected cash inflows based on market rates and associated yield curves. For derivative contracts with the same counterparty where the Company has a master netting arrangement with the counterparty, the fair value of the asset/liability is presented on a net basis within the consolidated balance sheets. Changes in the fair value of derivative financial instruments are recognized in the consolidated statements of operations within interest expense or other expense, net, unless specific hedge accounting criteria are met. Cash flows associated with derivative financial instruments are recognized in the operating section of the consolidated statements of cash flows. For derivatives designated as cash flow hedges, changes in the fair value of the derivative are recorded to AOCI and are reclassified to earnings when the underlying forecasted transaction affects earnings. For contracts designated as cash flow hedges, we reassess the probability of the underlying forecasted transactions occurring on a quarterly basis. For derivatives not designated as hedging instruments, all changes in fair value are recorded to earnings in the current period.
Earnings per share	Earnings per share Basic earnings per share is based on the weighted average number of common shares outstanding during each period. Diluted earnings per share is based on the weighted average number of common shares and dilutive common share equivalents outstanding during each period. The Company reflects common share equivalents relating to stock options, non-vested restricted stock and non-vested restricted stock units in its computation of diluted weighted average shares outstanding, unless the effect of inclusion is anti-dilutive. The effect of dilutive securities is calculated using the treasury stock method. We consider restricted stock awards to be participating securities, since holders of such shares have non-forfeitable dividend rights in the event the Company declares a common stock dividend.
