| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Principles of Consolidation | The accompanying Consolidated Financial Statements have been prepared in accordance with GAAP and include the accounts of Element Solutions and all of its controlled subsidiaries. The Company consolidates the income, expenses, assets, liabilities and cash flows of its subsidiaries from the date it acquires control or becomes the primary beneficiary. All intercompany accounts and transactions have been eliminated upon consolidation. |
| Basis of Presentation | In preparing the Consolidated Financial Statements in conformity with GAAP, management uses estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Management applies judgment based on its understanding and analysis of the relevant circumstances, including historical experience and future expectations. These judgments, by their nature, are subject to an inherent degree of uncertainty and, accordingly, actual results could differ significantly from these estimates and assumptions. |
| Cash and Cash Equivalents | The Company considers all highly liquid instruments purchased with an original maturity of three months or less to be cash equivalents. |
| Receivables and Allowance for Doubtful Accounts | The Company determines its allowance for doubtful accounts associated with expected credit losses using a combination of factors to reduce trade receivable balances to their estimated net realizable amount. The Company maintains and adjusts its allowance for credit losses based on a variety of factors, including the length of time receivables have been past due under the applicable contractual terms, current and future macroeconomic trends and conditions, significant one-time events such as bankruptcy filings or deterioration in the customer’s operating results or financial position, historical experience and the financial condition of its customers. Credit risk with respect to accounts receivable is generally diversified due to the large number of entities comprising the Company's customer base and its dispersion across many different geographical regions. |
| Inventories | Inventories are stated at the lower of cost or net realizable value with cost being determined by the first-in/first-out and average cost methods. The Company regularly reviews inventories for obsolescence and excess quantities and calculates reserves based on historical write-offs, customer demand, age of inventory, product evolution, usage rates and quantities of stock on hand. Additional obsolescence reserves may be required if actual sales are less favorable than those projected or product lifecycles differs from expectations. |
| Property, Plant and Equipment | Property, plant and equipment is stated at cost less accumulated depreciation. The Company records depreciation on a straight-line basis over the estimated useful life of each asset. Estimated useful lives by asset class are as follows: Average useful life (in years) Buildings and building improvements 5 to 20 Machinery, equipment and fixtures 3 to 15 Computer hardware and software 3 to 7 Furniture and automobiles 3 to 7 Leasehold improvements Lesser of useful life or lease term Maintenance and repair costs are expensed as incurred, while renewals and improvements, which significantly extend the useful life of the asset, are capitalized and expensed over its remaining useful life. Costs and accumulated depreciation on assets retired or disposed of are removed from the accounts and any resulting gains or losses are recorded to earnings in the period of disposal. |
| Business Combinations | The Company allocates the purchase price of acquisitions to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. The excess of the acquisition price over those estimated fair values is recorded as goodwill. Changes to the acquisition date provisional fair values prior to the end of the measurement period are recorded as adjustments to the associated goodwill. Acquisition-related expenses and restructuring costs, if any, are expensed as incurred. |
| Goodwill | Goodwill is tested for impairment at the reporting unit level annually in the fourth quarter, or when events or changes in circumstances indicate that goodwill might be impaired. The Company's reporting units are determined based upon its organizational structure in place at the date of the goodwill impairment test.The Company tests for impairment by comparing the fair value of each reporting unit to its carrying value. The fair value of each reporting unit is based equally on market multiples and the present value of discounted future cash flows. Excluding certain nonrecurring charges, the discounted cash flows are prepared based upon cash flows at the reporting unit level. The cash flow model utilized in the goodwill impairment test involves significant judgments related to future growth rates and discount rates, among other considerations from the vantage point of a market participant. If the fair value of a reporting unit exceeds the carrying value of the net assets assigned to that reporting unit, goodwill is not impaired and no further testing is required. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, the goodwill impairment loss is calculated as the difference between these amounts, limited to the amount of goodwill allocated to the reporting unit. The primary components of and assumptions used in the assessment consist of the following: • Valuation Techniques - the Company uses a discounted cash flow analysis, which requires assumptions about short and long-term net cash flows, growth rates and discount rates. Additionally, it considers guideline company and guideline transaction information, where available, to aid in the valuation of the reporting units. • Growth Assumptions - Multi-year financial forecasts are developed for each reporting unit by considering several key business drivers, such as new business initiatives, client service and retention standards, market share changes, historical performance and industry and economic trends, among other considerations. • Discount Rate Assumptions - Discount rates are estimated based on the WACC, which combines the required return on equity and considers the risk-free interest rate, market risk premium, size risk premium and a company specific risk premium, with the cost of debt, based on rated corporate bonds, adjusted using an income tax factor. • Estimated Fair Value and Sensitivitie s - The estimated fair value of each reporting unit is derived from the valuation techniques described above. The estimated fair value of each reporting unit is analyzed in relation to numerous market and historical factors, including current economic and market conditions, company-specific growth opportunities and guideline company information. |
| Indefinite-Lived Intangible Assets | Indefinite-lived intangible assets are reviewed for potential impairment on an annual basis, in the fourth quarter, or more frequently when events or circumstances indicate that such assets may be impaired, by comparing their estimated fair values to their carrying values. An impairment charge is recognized when the carrying value of an indefinite-lived intangible asset exceeds its estimated fair value. The Company uses the “relief from royalty” method to estimate the fair value of trade name intangible assets for impairment. The primary assumptions used to estimate the present value of cash flows from such assets include sales projections and growth rates being applied to a prevailing market-based royalty rate, the effects of which are then tax effected and discounted using the WACC from the vantage point of a market participant. Assumptions concerning sales projections are impacted by the uncertain nature of global and local economic conditions in the various markets it serves. |
| Finite-Lived Intangible Assets | Finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives, which currently range from 8 to 25 years for customer relationships, 3 to 10 years for developed technologies, 5 to 20 years for trade names and up to 5 years for other intangible assets. If circumstances require a long-lived asset group to be tested for possible impairment, the Company first determines if the estimated undiscounted future pre-tax cash flows expected to result from the use of the asset plus net proceeds expected from disposition of the asset, if any, are less than the carrying value of the asset. When an impairment is identified, the carrying value of the asset is reduced to its estimated fair value. |
| Leases | The Company adopted ASU No. 2016-02, "Leases" on January 1, 2019. This ASU required lessees to recognize most leases in their balance sheets, but to continue to record expenses on their income statements in a manner similar to past accounting. The Company determines if an arrangement is a lease at inception. Right-of-use (or ROU) assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The interest rate used to determine the present value of future lease payments is the Company's incremental borrowing rate, as the implicit rate in its leases is not readily determinable. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis for borrowings with similar terms and payments. The Company's leases may include variable payments such as common area maintenance, insurance, real estate taxes, changes in price indices or other costs, which are expensed as incurred. ROU assets also include any lease payments made prior to commencement and are recorded net of any lease incentives received. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. Lease expense for fixed lease payments is recognized on a straight-line basis over the lease term. |
| Contingencies and Commitments | The Company records accruals for loss contingencies and commitments which are both probable and reasonably estimable. Significant judgment is required to determine both probability and the estimated amount of loss. The Company reviews accruals on a quarterly basis and adjusts, as necessary, to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other current information. Legal fees are expensed as incurred. |
| Environmental Matters | The Company accrues for environmental matters when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current laws and existing technologies. Costs related to environmental contamination treatment and cleanup are charged to expense. The accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the Consolidated Balance Sheets as “Accrued expenses and other current liabilities” and “Other liabilities” at undiscounted amounts. Receivables for related insurance or other third-party recoveries for environmental liabilities are recorded when it is probable that a recovery will be realized and are included in the Consolidated Balance Sheets as “Other current assets" and "Other assets." |
| Employee Benefits | Amounts recognized in the Company's Consolidated Financial Statements related to pension and other post-retirement benefits are determined from actuarial valuations. Inherent in such valuations are assumptions including expected return on plan assets, discount rates at which the liabilities could be settled, rates of increase in future compensation levels and mortality rates. These assumptions are updated annually and are disclosed in Note 10, Pension, Post-Retirement and Post-Employment Plans , to the Consolidated Financial Statements. Actual results that differ from the assumptions are recorded in "Accumulated other comprehensive loss" within Stockholders’ Equity and amortized over future periods and, therefore, affect expense recognized. |
| Derivatives | The Company recognizes all contracts that meet the definition of a derivative as either assets or liabilities in the Consolidated Balance Sheets and measures those instruments at fair value. To designate a derivative for hedge accounting at inception and throughout the hedge period, the Company formally documents the nature and relationships between hedging instrument and hedged item, as well as its risk-management objectives and strategies for undertaking various hedge transactions, and the method of assessing hedge effectiveness. Additionally, for hedges of forecasted transactions, the significant characteristics and expected terms of forecasted transactions are specifically identified, and the likelihood of each forecasted transaction occurring is deemed probable. If it is determined that a forecasted transaction will not occur, a gain or loss is recognized in current earnings. Financial instruments qualifying for hedge accounting must maintain a specified level of effectiveness between the hedging instrument and the item being hedged, both at inception and throughout the hedged period. The Company does not engage in trading or other speculative uses of financial instruments. It is the Company's policy to disclose the fair value of derivative instruments that are subject to master netting arrangements on a gross basis in the Consolidated Balance Sheets.If hedge accounting is applied, the effective portion of unrealized gains and losses associated with the derivatives are deferred as a component of "Accumulated other comprehensive loss" until the underlying hedged transactions are reported in the Company’s Consolidated Statements of Operations. For derivative contracts not designated as hedging instruments, the Company records changes in the net fair value of the such contracts in "Other (expense) income, net" in the Consolidated Statements of Operations. |
| Financial Instruments | The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, investments, accounts payable and debt. The Company believes that the carrying value of the cash and cash equivalents, accounts receivable and accounts payable are representative of their respective fair values because of their short maturities. Available for sale equity investments are carried at fair value. |
| Foreign Currency Translation | The Company’s foreign subsidiaries primarily use their local currency as their functional currency. The assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars using foreign currency exchange rates prevailing at the balance sheet dates. The Consolidated Statements of Operations are translated at average foreign currency exchange rates for the periods presented. Cumulative currency translation adjustments are included in the stockholders’ equity section of the Consolidated Balance Sheets as "Accumulated other comprehensive loss." Net gains and losses from transactions denominated in currencies other than the functional currency of the entity are included in the Consolidated Statements of Operations as "Foreign exchange (loss) gain." |
| Revenue Recognition | The Company recognizes revenue either upon shipment or delivery of product depending on when it is reasonably assured that both title and the risks and rewards of ownership have been passed on to the customer, the Company's performance obligations have been fulfilled and collectability is probable. Estimates for sales rebates, incentives and discounts, as well as sales returns and allowances, are accounted for as reductions of revenue when the earnings process is complete. Sales rebates, incentives and discounts are typically earned by customers based on annual sales volume targets. The Company records an estimate for these accruals based on contract terms and its historical experience with similar programs, however, changes to these estimates may be required if the historical data used in the calculation differs from actual experience. Differences between estimated expense and actual costs are typically immaterial and are recognized in earnings in the period such differences are determined. Variable consideration for volume discounts, rebates and returns are recorded as contract liabilities and settled with the customer in accordance with the terms of the applicable contract, typically when program requirements are achieved by the customer.Most performance obligations relate to contracts with a duration of less than one year, in which the Company has the right to invoice the customer at the time the performance obligation is satisfied for the amount of revenue recognized at that time. The Company expenses incremental costs for obtaining contracts with terms of less than one year. |
| Research and Development | Research and development costs, which primarily relate to internal salaries, are expensed as incurred. |
| Income Taxes | The Company recognizes deferred tax assets and liabilities based on the differences between the financial statement basis and the tax basis of assets, liabilities, net operating losses and tax carryforwards. A valuation allowance is required to be recognized to reduce the recorded deferred tax asset to the amount that will more likely than not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income by jurisdiction during the periods in which those temporary differences become deductible or when carryforwards can be utilized. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in this assessment. If these estimates and related assumptions change in the future, the Company may be required to record additional valuation allowances against its deferred tax assets; resulting in additional income tax expense. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date of such change.The Company is subject to income taxes in the U.S. and in various states and foreign jurisdictions. Significant judgment is required in evaluating uncertain tax positions and determining provisions for income taxes. The first step in evaluating the tax position for recognition is to determine the amount of evidence that supports a favorable conclusion for the tax position upon audit. In order to recognize the tax position, the Company must determine whether it is more likely than not that the position is sustainable. The final evaluation step is to measure the tax benefit as the largest amount that has a more than 50% chance of being realized upon final settlement. Although the Company believes that the positions taken on income tax matters are reasonable, it establishes tax reserves in recognition that various taxing authorities may challenge certain of those positions taken, which may potentially result in additional tax liabilities. |
| Stock-Based Compensation Plans | Stock-based compensation is recorded in the Consolidated Statements of Operations as "Selling, technical, general and administrative" expense over the requisite service period based on the estimated grant-date fair value of the awards, effected for forfeitures as they occur. The fair value of RSU awards is determined using the closing price of Element Solutions' common stock on the date of grant. The fair value of stock options is determined using the Black-Scholes option pricing model and inputs in the model include assumptions related to stock price volatility, expected dividend yield and award terms. Compensation costs for awards with performance conditions are only recognized if and when it becomes probable that the performance conditions will be achieved. The probability of vesting is reassessed at the end of each reporting period and the compensation costs are adjusted accordingly, with the cumulative effect of such a change on current and prior periods being recognized in compensation cost in the period of the change. |
| Earnings (Loss) Per Share | Basic earnings (loss) per share excludes dilution and is computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share assumes the issuance of all potentially dilutive share equivalents using the if-converted or treasury stock methods, provided that the effects of which are not anti-dilutive. For stock options and RSUs, it is assumed that the proceeds will be used to buy back shares. For stock options, such proceeds equal the average unrecognized compensation plus the assumed exercise of weighted average number of options outstanding. For unvested RSUs, the assumed proceeds equal the average unrecognized compensation expense. |
| Fair Value Measurements | The Company determines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy. The basis for fair value measurements for each level within the hierarchy is described below, with Level 1 having the highest priority and Level 3 having the lowest. The three levels of the fair value hierarchy are as follows: • Level 1 – inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. • Level 2 – inputs are quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in non-active markets; and model-derived valuations whose inputs are observable or whose significant valuation drivers are observable. • Level 3 – inputs to valuation models are unobservable and/or reflect the Company’s market assumptions. The fair value hierarchy is based on maximizing the use of observable inputs and minimizing the use of unobservable inputs when measuring fair value. Classification within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company transfers the fair value of an asset or liability between levels of the fair value hierarchy at the end of the reporting period during which a significant change in the inputs used to determine the fair value has occurred. NAV Practical Expedient is the measure of fair value using the net asset value (or NAV) per share (or its equivalent) as an alternative to the fair value hierarchy discussed above. |
| Recently Issued Accounting Pronouncements Not Yet Adopted | Recently Issued Accounting Pronouncements Not Yet Adopted Income Taxes (Topic 740) - In December 2019, the FASB issued ASU No. 2019-12, "Simplifying the Accounting for Income Taxes," which removes certain exceptions related to the approach for intraperiod tax allocation, the recognition of deferred tax liabilities for outside basis differences and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The guidance is effective as of January 1, 2021, with early adoption permitted. The Company has evaluated ASU No. 2019-12 and the adoption of the guidance is not expected to have a material impact to our Consolidated Financial Statements. |
