Basis of Presentation
NOTE 1 – BASIS OF PRESENTATION
The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America for interim financial information and with the instructions to Form
10-Q
and Article 10 of Regulation
S-X
under the Securities Exchange Act of 1934. Accordingly, they do not include all the information and notes necessary for a comprehensive presentation of financial position, results of operations and cash flows.
It is our opinion, however, that all adjustments (consisting of normal, recurring adjustments, unless otherwise disclosed) have been made which are necessary for the condensed consolidated financial statements to be fairly stated. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form
10-K
for the year ended December 31, 2021 filed on February 16, 2022 (the “2021 Form
10-K”).
The results for the interim period covered by this report are not necessarily indicative of the results to be expected for the full year.
When we use the terms “Innospec,” “the Corporation,” “the Company,” “Registrant,” “we,” “us” and “our,” we are referring to Innospec Inc. and its consolidated subsidiaries unless otherwise indicated or the context otherwise requires.

cost
and actuarial net losses are a reclassification out of accumulated other comprehensive loss into other income and expense.
In addition, we have obligations for post-employment benefits in some of our other European businesses. As at March 31, 2022, we have recorded a liability of $4.6 million (December 31, 2021 – $4.6 million).

All of the $16.3 million of unrecognized tax benefits, interest and penalties would impact our effective tax rate if recognized.
In 2021 a
non-U.S.
subsidiary, Innospec Limited, entered into a review by the U.K. tax authorities under the U.K.’s Profit Diversion Compliance Facility (“PDCF”). The Company determined that additional tax and interest totaling $1.0 million may arise during the course of the PDCF review process which is currently ongoing.
A
non-U.S.
subsidiary, Innospec Performance Chemicals Italia Srl, is subject to an ongoing tax audit in relation to the period 2011 to 2014 inclusive. The Company has determined that additional tax, interest and penalties totaling $3.2 million may arise as a consequence of the tax audit. This includes a reduction for foreign exchange movements of $0.1 million recorded in the three months to March 31, 2022. As any additional tax arising as a consequence of the tax audit would be reimbursed by the previous owner under the terms of the sale and purchase agreement, an indemnification asset of the same amount is recorded in the financial statements to reflect this arrangement.
In 2018 the Company recorded an unrecognized tax benefit in relation to a potential adjustment that could arise as a consequence of the Tax Cuts and Jobs Act of 2017 (“Tax Act”), but for which retrospective adjustment to the filed 2017 U.S. federal income tax returns was not permissible. The Company has determined that additional tax, interest and penalties totaling $12.1 million may arise in relation to this item. This includes an increase in interest accrued of $0.1 million in the three months to March 31, 2022.
The Company and its U.S. subsidiaries remain open to examination by the IRS for certain elements of year 2017 and for years 2018 onwards under the statute of limitations. The Company’s subsidiaries in foreign tax jurisdictions are open to examination including the U.K. (2017 onwards), Switzerland (2017 onwards), Germany (2018 onwards), Spain (2018 onwards) and France (2019 onwards).

NOTE 9 – 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.

The following methods and assumptions were used to estimate the fair values:
Cash and cash equivalents:
The carrying amount approximates fair value because of the short-term maturities of such instruments.
Emissions Trading Scheme credits:
The fair value is determined by the open market pricing at the end of the reporting period.
Derivatives:
The fair value of derivatives relating to foreign currency forward exchange contracts are derived from current settlement prices and comparable contracts using current assumptions. Foreign currency forward exchange contracts primarily relate to contracts entered into to hedge future known transactions or hedge balance sheet net cash positions. The movements in the carrying amounts and fair values of these contracts are largely due to changes in exchange rates against the U.S. dollar.
Finance leases:
Finance leases relate to certain fixed assets in our Fuel Specialties and Oilfield Services segments. The carrying amount of finance leases approximates to the fair value.
Stock equivalent units:
The fair values of stock equivalent units are calculated at each balance sheet date using either the Black-Scholes or Monte Carlo method depending on the terms of each grant.

Derivative Instruments and Risk Management
NOTE 11 – DERIVATIVE INSTRUMENTS AND RISK MANAGEMENT
The Company enters into various foreign currency forward exchange contracts to minimize currency exchange rate exposure from expected future cash flows. As at March 31, 2022, the contracts have maturity dates of up to twelve months at 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 the first three months of 2022 was a gain of $0.8 million (first three months of 2021 – a gain of $1.3 million).

NOTE 12 – CONTINGENCIES
Legal matters
While we are involved from time to time in claims and legal proceedings that result from, and are incidental to, the conduct of our business including business and commercial litigation, employee and product liability claims, there are no material pending legal proceedings to which the Company or any of its subsidiaries is a party, or of which any of their property is subject. It is possible, however, that an adverse resolution of an unexpectedly large number of such individual claims or proceedings could in the aggregate have a material adverse effect on the results of operations for a particular year or quarter.
Guarantees
The Company and certain of the Company’s consolidated subsidiaries are contingently liable for certain obligations of affiliated companies primarily in the form of guarantees of debt and performance under contracts entered into as a normal business practice. This includes guarantees of
non-U.S.
excise taxes and customs duties. As at March 31, 2022, such guarantees which are not recognized as liabilities in the condensed consolidated financial statements amounted to $5.6 million (December 31, 2021 - $4.6 million). The remaining terms of the fixed maturity guarantees are up to 4 years and six months, with some further guarantees having no fixed expiry date.
Under the terms of the guarantee arrangements, generally the Company would be required to perform should the affiliated company fail to fulfil its obligations under the arrangements. In some cases, the guarantee arrangements have recourse provisions that would enable the Company to recover any payments made under the terms of the guarantees from securities held of the guaranteed parties’ assets.
The Company and its affiliates have numerous long-term sales and purchase commitments in their various business activities, which are expected to be fulfilled with no adverse consequences material to the Company.

As of March 31, 2022, there was $33.2 million of total unrecognized compensation cost related to nonvested share-based compensation arrangements. That cost is expected to be recognized over a weighted-average period of 1.96 years.
