Accounting Policies [Abstract] | |
Accounting Policies | Note 2. Accounting Policies Basis of preparation: Use of estimates: Revenue recognition: on-demand While some of our customers have payment terms beyond 30 days, we do not provide extended payment terms of a year or more, nor do our contracts include a financing component. Some of our contracts include variable consideration in the form of rebates. We record rebates at the point of sale as a reduction in sales when we can reasonably estimate the amount of the rebate. The estimates are based on our best judgment at the time of sale, which includes anticipated as well as historical performance. Taxes assessed by a governmental authority which are concurrent with sales to our customers, including sales, use, value-added, and revenue-related excise taxes, are collected by us from the customer and are not included in net sales, but are reflected in accrued liabilities until remitted to the appropriate governmental authority. When we are responsible for shipping and handling costs after title has transferred, we account for those as fulfilment costs and include them in cost of goods sold. Components of net sales: Components of cost of goods sold: non-recoverable Components of selling, general and administrative expenses: Research and development expenses: Earnings per share: Foreign currencies: where the U.S. dollar is the functional currency no gains or losses on translation occur, and gains or losses on monetary assets relating to currencies other than the U.S. dollar are taken to the income statement in other income/(expense), net. Gains and losses on intercompany foreign currency loans which are long-term in nature, which the Company does not intend to settle in the foreseeable future, are also recorded in accumulated other comprehensive loss. Other foreign exchange gains or losses are also included in other income, net in the income statement. Share Business combinations: The determination of the fair values of certain assets and liabilities are usually based on significant estimates provided by management, such as forecast revenue or profit. In determining the fair value of intangible assets, an income approach is generally used and may incorporate the use of a discounted cash flow method. In applying the discounted cash flow method, the estimated future cash flows and residual values for each intangible asset are discounted to a present value using a discount rate appropriate to the business being acquired. These cash flow projections are based on management’s estimates of economic and market conditions including revenue growth rates, operating margins, capital expenditures and working capital requirements. Cash equivalents: Trade and other accounts receivable: The Company is exposed to credit losses primarily through sales of products. The Company’s expected loss allowance methodology for trade and other accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the current status of customers’ receivables. Due to the short-term nature of such receivables, the estimate of accounts receivable amounts that may not be collected is based on aging of the accounts receivable balances and the financial condition of customers. Additionally, a further allowance is included to account for the Company’s historic track record of credit losses, for balances which are not aged sufficiently to be considered under the aging based approach . Inventories: Property, plant and equipment: Buildings 7 to 25 years Equipment 3 to 10 years Goodwill: Initially we perform a qualitative assessment to determine whether it is more likely than not (that is, a likelihood of more than 50 percent) that the fair value of a reportable segment is less than the carrying amount prior to performing a quantitative goodwill impairment test. The annual measurement date for impairment assessment of the goodwill relating to the Performance Chemicals, Fuel Specialties and Oilfield Services segments is December 31 each year. Factors utilized in the qualitative assessment process include macroeconomic conditions, industry and market considerations, cost factors, overall financial performance and Company specific events. If a quantitative test is required, we assess the fair value based on projected post-tax projected operating margins, changes in working capital and discount rates. We would develop these assumptions by considering recent financial performance and industry growth estimates. O ther intangible assets: . In order to facilitate testing for potential impairment the Company groups together assets at the lowest possible level for which cash flow information is available. Undiscounted future cash flows expected to result from the asset groups are compared with the carrying value of the assets and, if such cash flows are lower, an impairment loss may be recognized. The amount of the impairment loss is the difference between the fair value and the carrying value of the assets. Fair values are determined using post-tax non-cash The estimated useful lives of the major classes of assets are as follows: Technology 10 to 17 years Customer lists 10 to 15 years Brand names 5 to 10 years Product rights 9 to 10 years Internally developed software 3 to 10 years Marketing related 11 years Leases: right-of-use non-current) non-current) Operating lease ROU assets and operating lease liabilities are recognized based on the present value of future lease payments over the remaining lease term. Very few of our leases have renewal options or early termination break clauses, but where they do we have assessed the term of the lease based on any options being exercised only if they are reasonably certain. As most of our leases do not provide an implicit interest rate, we use our incremental borrowing rate based on the information available at point of recognition in determining the present value of future payments. The operating lease ROU asset excludes lease incentives and initial direct costs incurred. Lease expense for lease payments is recognized on a straight-line basis over the lease term unless payments are variable per the agreement. We do not separate related non-lease We do not recognize a ROU asset or operating lease liability for short-term leases (with a length of one year or less), and any associated cost is recognized, as incurred, through the income statement . Deferred finance costs: Impairment of long-lived assets: post-tax Derivative instruments: From non-current earnings. Plant closure provisions: This Movements in the Projected Benefit Obligation (“PBO”) are dependent on our assumptions in respect of the discount rate, annual member mortality rates, future return on assets and future inflation. Income taxes: and extend to environmental liabilities that result from other-than-normal operation of long-lived assets, for example pollution. Remediation costs relate to asset retirement obligations at our current and former manufacturing sites following retirement of the long-lived assets, linked to their normal operation. We recognize environmental liabilities when they are probable and the costs can be reasonably estimated, and asset retirement obligations when there is an obligation based on a legal requirement , including those arising from a The Company must comply with environmental legislation in the countries in which it operates or has operated in and annually reassesses the program of work required. This includes estimating the credit-adjusted risk free rate and the timing and cost of performing the remediation work. Management receives input from specialists to develop these estimates and assumptions utilizing the latest information available together with experience of recent costs. While we believe our assumptions for the liabilities are reasonable, they are subjective estimates and it is possible that variations in any of the assumptions will result in materially different calculations to the liabilities we have reported. Costs of future obligations are discounted to their present values using the Company’s credit-adjusted risk-free rate. Pension plans and other post-employment benefits: year-end. In May 2022, the Trustees of the United Kingdom defined benefit pension plan (“UK Plan”) entered into an agreement with Legal and General Assurance Society Limited to acquire an insurance policy that operates as an investment asset, with the intent of matching the remaining uninsured part of the UK Plan’s future cash outflow arising from the accrued pension liabilities of members. Such an arrangement is commonly termed as a “buy-in”. buy-in buy-in |

Segment Reporting [Abstract] | |
Segment Reporting | Note 3. Segment Reporting and Geographical Area Data The Performance Chemicals, Fuel Specialties and Oilfield Services segments operate in markets where we actively seek growth opportunities although their ultimate customers are different. The Octane Additives segment ceased trading and is no longer a reporting segment from July 1, 2020. Our Performance Chemicals segment provides effective technology-based solutions for our customers’ processes or products focused in the personal care, home care, agrochemical, mining and other industrial markets. Our Fuel Specialties segment develops, manufactures, blends, markets and supplies a range of specialty chemicals products used as additives to a wide range of fuels. Our Oilfield Services segment develops and markets chemical solutions for fracturing, drilling, stimulation and completion operations, products for oil and gas production and transport which aid flow assurance and maintain asset integrity. The Octane Additives business has ceased trading and is no longer a reporting segment from July 1, 2020 as the production of TEL for use in motor gasoline has finished. Legacy costs related to these operations are now being recorded as operating expenses within corporate costs. In 2022, the Company had a significant customer in the Oilfield Services segment which accounted for $222.2 million (11.3%) of our net group sales.

The components in each segment (including products, markets and competitors) have similar economic characteristics and the segments, therefore, reflect the lowest level at which operations and cash flows can be clearly distinguished, operationally and for financial reporting purposes, from the rest of the Company. The Company assesses goodwill for impairment on at least an annual basis, initially based on a qualitative assessment to determine whether it is more likely than not that the fair value of a segment is less than the carrying amount. If a potential impairment is identified then an impairment test is performed. The Company performed its annual impairment assessment in respect of goodwill as at December 31, 2022, 2021 and 2020. Our impairment assessment concluded that there had been no impairment of goodwill in respect of those reporting units. We believe that where appropriate the assumptions used in our impairment assessments are reasonable, but that they are judgmental, and variations in any of the assumptions may result in materially different calculations of any potential impairment charges. |

Retirement Benefits [Abstract] | |
Pension and Post-Employment Benefits | Note 10. Pension and Post-Employment Benefits United Kingdom plan The Company maintains a defined benefit pension plan covering certain current and former employees in the United Kingdom (the “UK Plan”). The UK Plan is closed to future service accrual and has a large number of deferred and current pensioners. The Projected Benefit Obligation (“PBO”) is based on final salary and years of credited service reduced by social security benefits according to a plan formula. Normal retirement age is 65 but provisions are made for early retirement. In May 2022, the Trustees of the UK Plan entered into an agreement with Legal and General Assurance Society Limited to acquire an insurance policy that operates as an investment asset, with the intent of matching the remaining uninsured part of the UK Plan’s future cash outflow arising from the accrued pension liabilities of members. Such an arrangement is commonly termed as a “buy-in”. buy-in improving the security to the UK Plan and its members. The Company consequently benefits from the buy-in In 2022, the Company contributed $0.0 million (2021 – $0.0 million) in cash to the UK Plan in accordance w ith a there The service cost shown in the table below has been recognized in sel ling, gen and admi corporate (in millions) 2022 2021 2020 Service cost $ 2.2 $ 1.6 $ 1.2 Interest cost on PBO 10.1 7.6 11.2 Expected return on plan assets (16.0 ) (15.5 ) (17.8 ) Amortization of prior service cost/(credit) 0.5 0.3 (0.5 ) Amortization of actuarial net losses — 1.6 0.9 Settlement event — (0.3 ) — Net periodic benefit $ (3.2 ) $ (4.7 ) $ (5.0 ) Plan assumptions at December 31, (%): 20 22 2021 2020 Discount rate 4.91 1.84 1.36 Inflation rate 2.85 3.55 2.35 Rate of return on plan assets – overall on bid-value 4.00 2.30 2.00 Plan asset allocation by category (%): 2022 2021 2020 Debt securities and insurance contracts 96 82 86 Equity securities and real estate — 5 10 Cash 4 13 4 100 100 100 Following the buy-in, The inflation rate is derived using a similar cash flow matched methodology as used for the discount rate but having regard to the difference between yields on fixed interest and index linked United Kingdom government gilts. A % change in the discount rate assumption would change the PBO at December 31, 2022 by approximately $ million and the net pension credit for 2023 would change by approximately $ million. A % change in the level of price inflation assumption would change the PBO at December 31, 2022 by approximately $ million and the net pension credit for 2022 by approximately $ million. Movements in PBO and fair value of UK Plan assets are as follows: (in millions) 2022 2021 Change in PBO: Opening balance $ 679.1 $ 758.7 Interest cost 10.1 7.6 Service cost 2.2 1.6 Benefits paid (45.6 ) (37.3 ) Settlements — (10.6 ) Plan amendments 0.4 5.4 Actuarial losses/(gains) (174.2 ) (40.5 ) Exchange effect (68.0 ) (5.8 ) Closing balance $ 404.0 $ 679.1 Fair value of plan assets: Opening balance $ 838.9 $ 876.7 Benefits paid (45.6 ) (37.3 ) Settlements — (10.6 ) Actual return on assets (258.7 ) 17.5 Exchange effect (82.5 ) (7.4 ) Closing balance $ 452.1 $ 838.9 Net pension asset $ 48.1 $ 159.8 Due to the UK Plan being closed to future accrual the PBO is equal to the Accumulated Benefit Obligation. The UK Plan holds approximately % (December 31, 2021 – %) of the UK non-U . . governments and government agencies. No more than % of the UK Settlement The 2021 settlement threshold for the total of interest cost and service cost was triggered in October 2021 by the level of transfers paid out of the UK Plan during the year. As a result, a settlement value of $10.6 million has been included for the PBO movements in 2021.

Foreign tax credits can fully or partially offset these incremental U.S. taxes from foreign income inclusions. The utilization of foreign tax credits varies year on year as this is dependent on a number of variable factors which are difficult to predict and may prevent offset. The effective tax rate is negatively impacted by the net impact of foreign inclusions post foreign tax credit usage in 2022. As a consequence of the Company having operations outside of the U.S., it is exposed to foreign currency fluctuations. These have had a negative impact on the effective tax rate in 2022. In 2022 there was an increase in the level of profits arising in the U.S. compared to prior periods. This has increased the amount of state and local taxes falling due, which has had a negative impact on the effective tax rate, but has also increased the level of foreign-derived intangible income benefit that the Company is entitled to, which has had a positive impact on the effective tax rate in the year. Other items do not have a significant impact on the effective tax rate. Details of deferred tax assets and liabilities are analyzed as follows: (in millions) 2022 2021 Deferred tax assets: Stock compensation $ 3.7 $ 5.2 Net operating loss carry forwards 10.9 12.0 Other intangible assets 10.5 11.1 Accretion expense 3.2 3.2 Restructuring provision 1.7 2.0 Employee related liabilities 8.1 4.1 Foreign tax credits 0.8 1.9 Operating lease liabilities 11.8 10.6 Inventory provisions 6.6 3.6 Research and experimental expenditure 2.7 — Other 4.8 3.8 Subtotal 64.8 57.5 Less valuation allowance (0.7 ) (0.8 ) Total net deferred tax assets $ 64.1 $ 56.7 Deferred tax liabilities: Property, plant and equipment $ (22.5 ) $ (23.6 ) Intangible assets including goodwill (30.3 ) (29.8 ) Pension asset (10.9 ) (38.2 ) Customer relationships (3.4 ) (4.5 ) Unremitted overseas earnings (1.9 ) (1.9 ) Right-of-use (11.8 ) (10.6 ) Other (3.6 ) (2.5 ) Total deferred tax liabilities $ (84.4 ) $ (111.1 ) Net deferred tax liability $ (20.3 ) $ (54.4 ) Deferred tax assets $ 5.9 $ 6.4 Deferred tax liabilities (26.2 ) (60.8 ) $ (20.3 ) $ (54.4 ) The Company assesses the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets.

Debt Disclosure [Abstract] | |
Long-Term Debt | Note 12. Long-Term Debt As at December 31, 2022, and December 31, 2021, the Company has not drawn down on its revolving credit facility. The Company continues to have available a $250.0 million revolving credit facility until September 25, 2024. The facility contains an accordion feature whereby the Company may elect to increase the total available borrowings by an aggregate amount of up to $125.0 million. The deferred finance costs of $0.6 million (December 31, 2021 – $1.0 million) related to the arrangement of the credit facility, are included within other current and non-current (in millions) 2022 2021 Gross cost at January 1 $ 1.8 $ 1.8 Capitalized in the year — — 1.8 1.8 Accumulated amortization at January 1 $ (0.8 ) $ (0.5 ) Amortization in the year (0.4 ) (0.3 ) $ (1.2 ) $ (0.8 ) Net book value at December 31 $ 0.6 $ 1.0 Amortization expense was $0.4 million, $0.3 million and $0.4 million in 2022, 2021 and 2020, respectively. The charge is included in interest expense, see Note 2 of the Notes to the Consolidated Financial Statements. The obligations of the Company under the credit facility are secured obligations and guaranteed by certain subsidiaries of the Company. Amounts available under the revolving facility may be borrowed in U.S. dollars, Euros, British pounds and other freely convertible currencies. The Company’s credit facility contains restrictive clauses which may constrain our activities and limit our operational and financial flexibility. The facility obliges the lenders to comply with a request for utilization of finance unless there is an event of default outstanding. Events of default are defined in the credit facility and include a material adverse change to our assets, operations or financial condition. The facility contains a number of restrictions that limit our ability, amongst other things, and subject to certain limited exceptions, to incur additional indebtedness, pledge our assets as security, guarantee obligations of third parties, make investments, undergo a merger or consolidation, dispose of assets, or materially change our line of business. In addition, the credit facility contains terms which, if breached, would result in it becoming repayable on demand. It requires, among other matters, compliance with the following financial covenant ratios measured on a quarterly basis: (1) the ratio of net debt to EBITDA shall not be greater than 3.0:1 and (2) the ratio of EBITDA to net interest shall not be less than 4.0:1. Management has determined that the Company has not breached these covenants throughout the period to December 31, 2022 and does not expect to breach these covenants for the next 12 months. The weighted average rate of interest on borrowings was 0.00% at December 31, 2022 and 0.00% at December 31, 2021. Payments of interest on long-term debt were $0.0 million, $0.0 million and $0.8 million in 2022, 2021 and 2020, respectively. The net cash outflows in respect of refinancing costs were $0.0 million, $0.0 million and $0.3 million in 2022, 2021 and 2020, respectively. |

Plant Closure Provisions | Note 13. Plant Closure Provisions The Company has continuing plans to remediate manufacturing facilities at sites around the world as and when those operations are expected to cease or we are required to decommission the sites according to local laws and regulations. The liability for estimated plant closure costs includes costs for environmental remediation liabilities and asset retirement obligations. The principal site giving rise to asset retirement obligations is the manufacturing site at Ellesmere Port in the United Kingdom. There are also asset retirement obligations and environmental remediation liabilities on a much smaller scale in respect of other manufacturing sites. Movements in the provisions are summarized as follows: (in millions) 2022 2021 2020 Total at January 1 $ 56.5 $ 58.5 $ 49.3 Charge for the period excluding restructuring 5.3 3.9 5.1 Restructuring (see Note 5) — — 7.5 Utilized in the period (4.2 ) (5.3 ) (4.1 ) Exchange effect (0.4 ) (0.6 ) 0.7 Total at December 31 57.2 56.5 58.5 Due within one year (5.3 ) (5.2 ) (6.6 ) Due after one year $ 51.9 $ 51.3 $ 51.9 Amounts due within one year refer to provisions where expenditure is expected to arise within one year of the balance sheet date. The charge for the period in 2022 represents the accretion expense recognized of $3.8 million and a further $1.5 million primarily in respect of changes in the expected cost and scope of future remediation activities. The charges for plant closure provisions are recognized in cost of goods sold for our reporting segments and within selling, general and administrative expenses for Corporate costs. The Octane Additives segment ceased trading and is no longer a reporting segment from July 1, 2020. As a result, there was a one-off We recognize environmental remediation liabilities when they are probable and the costs can be reasonably estimated, and asset retirement obligations when there is an obligation based on a legal requirement, including those arising from a Company promise, and the costs can be reasonably estimated. The Company has to anticipate the program of work required and the associated future expected costs, and comply with environmental legislation in the countries in which it operates or has operated in. Expenditure utilizing plant closure provisions was $4.2 million, $5.3 million and $4.1 million in 2022, 2021 and 2020, respectively. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Note 14. Fair Value Measurements Fair value is 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 (exit price). The Company utilizes a mid-market inputs can be readily observable, market corroborated or generally unobservable. The Company primarily applies the market approach for recurring fair value measurements and endeavors to utilize the best available information. Accordingly, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The Company is able to classify fair value balances based on the observability of those inputs. The Company gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy Levels. In 2019, the Company evaluated the fair value hierarchy levels assigned to its assets and liabilities, and concluded that there should be no transfers into or out of Levels 1, 2 and 3. The following table presents the carrying amount and fair values of the Company’s assets and liabilities measured on a recurring basis: December 31, 2022 December 31, 2021 (in millions) Carrying Amount Fair Value Carrying Amount Fair Value Assets Non-derivatives: Cash and cash equivalents $ 147.1 $ 147.1 $ 141.8 $ 141.8 Derivatives (Level 1 measurement): Other current and non-current Emissions Trading Scheme credits 2.7 2.7 3.9 3.9 Liabilities Non-derivatives: Finance leases (including current portion) $ — $ — $ 0.1 $ 0.1 Derivatives (Level 1 measurement): Other current liabilities: Foreign currency forward exchange contracts 0.5 0.5 1.2 1.2 Non-financial Stock equivalent units 26.4 26.4 17.3 17.3 The following methods and assumptions were used to estimate the fair values: Cash and cash equivalents: Emissions Trading Scheme credits: Long-term debt: Derivatives: Stock equivalent units: |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivative Instruments and Risk Management | Note 15. Derivative Instruments and Risk Management The Company has limited involvement with derivative instruments and does not trade them. The Company does use derivatives to manage certain interest rate, foreign currency exchange rate, raw material cost exposures and greenhouse gases emission allowances, as the need arises. The Company previously entered into interest rate swap contracts to reduce interest rate risk on its core debt. As at December 31, 2022 and at December 31, 2021, there were no interest rate swaps in place. Interest rate swaps were previously in place to hedge interest rate risk on the term loan for a notional value that matched the repayment profile of the term loan. The Company enters into various foreign currency forward exchange contracts to minimize currency exchange rate exposure from expected future cash flows. As at December 31, 2022, foreign currency forward exchange contracts with a notional value of $161.1 million were in place (December 31, 2021 $113.0 million), with maturity dates of up to one year from the date of inception. These foreign currency forward exchange contracts have not been designated as hedging instruments, and their impact on the income statement for 2022 was a gain of $0.7 million (2021 – gain $1.0 million). As at December 31, 2022 and December 31, 2021 the Company did not hold any raw material derivatives. The Company participates in the new United Kingdom Emissions Trading Scheme (“UK ETS”) which was launched on January 1, 2021. Emissions trading schemes work on the ‘cap and trade’ principle, where a cap is set on the total amount of certain greenhouse gases that can be emitted by sectors covered by the scheme. This limits the total amount of carbon that can be emitted. Within this cap, participants receive free allowances and/or buy emission allowances at auction or on the secondary market which they can trade with other participants as needed. As at December 31, 2022, the Company held UK ETS credits of $2.7 million (December 31, 2021 – $3.9 million). The Company sells a range of specialty chemicals to major oil refiners and chemical companies throughout the world. Credit limits, ongoing credit evaluation and account monitoring procedures are intended to minimize bad debt risk. Collateral is not generally required. |

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
Share-Based Compensation Plans | Note 18. Share-Based Compensation Plans Stock option plans The Company has two stock option plans, the Omnibus Long-Term Incentive Plan and the ShareSave Plan 2008 under which it currently grants awards. The stock options have vesting periods ranging from 2 to 5 years and in all cases stock options granted expire within 10 years of the date of grant. All grants are at the sole discretion of the Compensation Committee of the Board of Directors. Grants may be priced at market value or at a premium or discount. The aggregate number of shares of common stock reserved for issuance which can be granted under the plans is 2,550,000. In the fourth quarter of 2020, a number of stock options that were granted to 14 employees in February 2018 were modified to extend the vesting period by two years. The incremental compensation cost resulting from the modifications was $2.4 million, resulting from the performance targets that were not achieved in 2020 being extended to a future period. The fair value of stock options is measured on the grant date using either the Black-Scholes model, or in cases where performance criteria are dependent upon external factors such as the Company’s stock price, using a Monte Carlo model. The Company’s policy is to issue shares from treasury stock to holders of stock options who exercise those options, but if sufficient treasury stock is not available, the Company will issue previously unissued shares of stock to holders of stock options who exercise options. Stock equivalent units The Company awards Stock Equivalent Units (“SEUs”) from time to time as a long-term performance incentive. SEUs are cash settled equity instruments conditional on certain performance criteria and the fair value is linked to the Innospec Inc. share price. SEUs have vesting periods ranging from six months to 5 years and in all cases SEUs granted expire within 10 years of the date of grant. Grants may be priced at market value or at a premium or discount. There is no limit to the number of SEUs that can be granted. As at December 31, 2022 the liability for SEUs of $26.4 million is included in accrued liabilities in the consolidated balance sheet, where they will remain In the fourth quarter of 2020, a number of SEUs that were granted to 61 employees in February 2018 were modified to extend the vesting period by two years. The adjusted compensation cost resulting from the modifications has been recognised by the fair valuation at the balance sheet date based on the extended vesting period. The fair value of SEUs is re-measured Compensation cost The compensation cost recorded for stock options was $6.7 million, $4.4 million and $5.8 million for 2022, 2021 and 2020, respectively. The compensation cost for stock options is based on the grant-date fair value and spread evenly over the vesting period. The compensation cost recorded for SEUs was $24.2 million, $3.1 million and $1.9 million for 2022, 2021 and 2020, respectively. The compensation cost for SEUs is spread over the life of the award subject to a revaluation to the fair value at each quarter end. The revaluation may result in a charge or a credit to the income statement in each quarter dependent upon our share price movements and other performance criteria. Forfeits are accounted for as an adjustment to the charge in the period in which the forfeits occur. Transactions in the period The fair value of each stock option or SEU granted in the year was estimated on the date of grant using the Black-Scholes option-pricing model and where appropriate the Monte Carlo simulation model. These models utilized the following weighted average assumptions to determine the grant-date fair values of the share-based compensation granted in the year: 2022 2021 2020 Dividend yield 1.27 % 1.17 % 1.15 % Expected life 5 years 5 years 5 years Volatility 39.8 % 40.2 % 27.4 % Risk free interest rate 2.90 % 0.45 % 1.10 % The dividend yield was based on our recent history of dividend payouts. The expected life was determined based upon historical exercise experience. The volatility was determined based upon the historical The following tables summarizes the transactions of the Company’s share-based compensation plans for the year ended December 31, 2022.

That cost is expected to be recognized over a weighted-average period of 1.9 years. The total intrinsic value of share-based compensation plans outstanding at December 31, 2022 was $71.5 million. The total intrinsic value of share-based compensation plans exercisable at December 31, 2022 was $9.7 million. The total intrinsic value of share-based compensation plans exercised for the year ended December 31, 2022 was approximately $18.1 million. The total cash paid for SEUs exercised for the year ended December 31, 2022 was approximately $15.0 million. The total fair value of share-based compensation that vested for the year ended December 31, 2022 was $13.0 million. The weighted-average grant-date fair value of share-based compensation plans granted during 2022, 2021, and 2020 was $60.2, $84.8, and $72.4, respectively. The Company recorded a current tax charge of $0.7 million in 2022, and a current tax benefit of $1.3 million and $1.6 million in 2021 and 2020, respectively, in relation to stock option compensation. This amount is inclusive of excess tax benefits. |

Some of our contracts include variable consideration in the form of rebates. We record rebates at the point of sale as a reduction in sales when we can reasonably estimate the amount of the rebate. The estimates are based on our best judgment at the time of sale, which includes anticipated as well as historical performance. Taxes assessed by a governmental authority which are concurrent with sales to our customers, including sales, use, value-added, and revenue-related excise taxes, are collected by us from the customer and are not included in net sales, but are reflected in accrued liabilities until remitted to the appropriate governmental authority. When we are responsible for shipping and handling costs after title has transferred, we account for those as fulfilment costs and include them in cost of goods sold. |

Due to the short-term nature of such receivables, the estimate of accounts receivable amounts that may not be collected is based on aging of the accounts receivable balances and the financial condition of customers. Additionally, a further allowance is included to account for the Company’s historic track record of credit losses, for balances which are not aged sufficiently to be considered under the aging based approach . |
Inventories | Inventories: |

Goodwill and other intangible assets | Goodwill: Initially we perform a qualitative assessment to determine whether it is more likely than not (that is, a likelihood of more than 50 percent) that the fair value of a reportable segment is less than the carrying amount prior to performing a quantitative goodwill impairment test. The annual measurement date for impairment assessment of the goodwill relating to the Performance Chemicals, Fuel Specialties and Oilfield Services segments is December 31 each year. Factors utilized in the qualitative assessment process include macroeconomic conditions, industry and market considerations, cost factors, overall financial performance and Company specific events. If a quantitative test is required, we assess the fair value based on projected post-tax projected operating margins, changes in working capital and discount rates. We would develop these assumptions by considering recent financial performance and industry growth estimates. O ther intangible assets: . In order to facilitate testing for potential impairment the Company groups together assets at the lowest possible level for which cash flow information is available. Undiscounted future cash flows expected to result from the asset groups are compared with the carrying value of the assets and, if such cash flows are lower, an impairment loss may be recognized. The amount of the impairment loss is the difference between the fair value and the carrying value of the assets. Fair values are determined using post-tax non-cash The estimated useful lives of the major classes of assets are as follows: Technology 10 to 17 years Customer lists 10 to 15 years Brand names 5 to 10 years Product rights 9 to 10 years Internally developed software 3 to 10 years Marketing related 11 years |
Leases | Leases: right-of-use non-current) non-current) Operating lease ROU assets and operating lease liabilities are recognized based on the present value of future lease payments over the remaining lease term. Very few of our leases have renewal options or early termination break clauses, but where they do we have assessed the term of the lease based on any options being exercised only if they are reasonably certain. As most of our leases do not provide an implicit interest rate, we use our incremental borrowing rate based on the information available at point of recognition in determining the present value of future payments. The operating lease ROU asset excludes lease incentives and initial direct costs incurred. Lease expense for lease payments is recognized on a straight-line basis over the lease term unless payments are variable per the agreement. We do not separate related non-lease We do not recognize a ROU asset or operating lease liability for short-term leases (with a length of one year or less), and any associated cost is recognized, as incurred, through the income statement . |

Derivative instruments | Derivative instruments: From non-current earnings. |
Plant closure provisions | Plant closure provisions: This and extend to environmental liabilities that result from other-than-normal operation of long-lived assets, for example pollution. Remediation costs relate to asset retirement obligations at our current and former manufacturing sites following retirement of the long-lived assets, linked to their normal operation. We recognize environmental liabilities when they are probable and the costs can be reasonably estimated, and asset retirement obligations when there is an obligation based on a legal requirement , including those arising from a The Company must comply with environmental legislation in the countries in which it operates or has operated in and annually reassesses the program of work required. This includes estimating the credit-adjusted risk free rate and the timing and cost of performing the remediation work. Management receives input from specialists to develop these estimates and assumptions utilizing the latest information available together with experience of recent costs. While we believe our assumptions for the liabilities are reasonable, they are subjective estimates and it is possible that variations in any of the assumptions will result in materially different calculations to the liabilities we have reported. Costs of future obligations are discounted to their present values using the Company’s credit-adjusted risk-free rate. |
Pension plans and other post-employment benefits | Pension plans and other post-employment benefits: year-end. In May 2022, the Trustees of the United Kingdom defined benefit pension plan (“UK Plan”) entered into an agreement with Legal and General Assurance Society Limited to acquire an insurance policy that operates as an investment asset, with the intent of matching the remaining uninsured part of the UK Plan’s future cash outflow arising from the accrued pension liabilities of members. Such an arrangement is commonly termed as a “buy-in”. buy-in buy-in Movements in the Projected Benefit Obligation (“PBO”) are dependent on our assumptions in respect of the discount rate, annual member mortality rates, future return on assets and future inflation. |
