Organization, Consolidation and Presentation of Financial Statements [Abstract]  
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, 2019 filed on February 19, 2020 (the “2019 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.
Credit losses
With an effective date of January 1, 2020, we have applied Accounting Standards Update (ASU) No. 2016-13, Financial Instruments – Credit Losses (ASC Topic 326). This replaces the incurred loss impairment methodology under previous GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.
The standard was adopted using prospective application and principally impacts the allowance for trade and other accounts receivables. Upon adoption, there was no adjustment made to opening retained earnings as at January 1, 2020. As a result of implementing the standard, the Company did not recognize any material change to the allowance within trade and other accounts receivable as at January 1, 2020. Trade
and
 other accounts receivable are shown net of a $4.3 million allowance at June 30, 2020. The allowance remains immaterial to the financial statements.
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.
The Company considered the current and expected future economic
and
 market conditions surrounding the COVID-19 pandemic and determined that the estimate of credit losses was not significantly impacted.

Segment Reporting
NOTE 2 – SEGMENT REPORTING
The Company reports its financial performance based on the following four reportable segments: Fuel Specialties, Performance Chemicals, Oilfield Services and Octane Additives.
The Fuel Specialties, Performance Chemicals and Oilfield Services segments operate in markets where we actively seek growth opportunities although their ultimate customers are different. The Company expects that the Octane Additives segment will not make any further sales and will cease to be a reporting segment from January 1, 2021, see Note 4 of the Notes to the Condensed Consolidated Financial Statements for further information.
The Company evaluates the performance of its segments based on operating income. The following tables analyze sales and other financial information by the Company’s reportable segments:

Restructuring
NOTE 4 – RESTRUCTURING
During the quarter ended June 30, 2020, the Company has recorded provisions of $21.1 million for the restructuring of its Octane Additives segment in line with the end of the manufacturing and sale of tetra ethyl lead (“TEL”) for use in motor gasoline. The Company expects that the Octane Additives segment will not make
 any
further sales
and will cease to be a reporting segment from January 1, 2021
. Production of TEL will continue for sales to the aviation market, as reported within our Fuel Specialties segment.
The provisions comprise the future committed costs of environmental monitoring
 
of $2.0 million,
remediation of facilities of $7.5 million, provision for
 
a
 
loss making contract of $7.2 million, impairment of tangible assets of $2.0 million and costs of redundancy due to the
down-sizing
of the TEL operations of $2.4 million.

During the quarter ended June 30, 2020, the Company impaired the intangible assets arising from the acquisition of Strata Control Services Inc., which forms part of our Oilfield Services segment. The impairment review was triggered by the reduction in demand for drilling related products. A discounted cash flow analysis was performed to determine the fair value of the assets, linked to the down turn in the results of that segment. The impaired assets relate to technology ($10.0 million) and customer relationships ($9.8 million).
The amortization expense for the six months ended June 30, 2020 was $11.5 million (six months ended June 30, 2019 – $11.5 million).

The Company maintains a defined benefit pension plan (the “Plan”) covering a number of its current and former employees in the United Kingdom, although it does also have other much smaller pension arrangements in the U.S. and overseas. The Plan is closed to future service accrual but has a large number of deferred and current pensioners.
The net service cost for the three and six months ended June 30, 2020 was $0.3 million and $0.6 million respectively (three and six months ended June 30, 2019 – $0.3 million and $0.5 million respectively) and has been recognized in selling, general and administrative expenses within corporate costs.

The Company also maintains an unfunded defined benefit pension plan covering a number of its current and former employees in Germany (the “German plan”) within our Fuel Specialties segment. The German plan is closed to new entrants and has no assets. The net service cost for the German plan for the three and six months ended June 30, 2020 was $0.1 million and $0.1 million respectively (three and six months ended June 30, 2019 – $0.1 million and $0.1 million respectively) and has been recognized in selling, general and administrative expenses.

All of the $15.2 million of unrecognized tax benefits, interest and penalties would impact our effective tax rate if recognized.
As previously disclosed, 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 $3.1 million may arise as a consequence of the tax audit. This includes a reduction in interest accrued of $0.2 million recorded in the six months to June 30, 2020. 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.
As previously disclosed, 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, 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
 
accr
u
ed
 
of $0.4 million in the six months to June 30, 2020
.
In 2015, the Company recorded an unrecognized tax benefit of $1.2 million in relation to additional tax that could have arisen if a historical impairment in value of certain of the Company’s
non-U.S.
subsidiaries was reversed upon challenge by the tax authorities. The Company has released the provision of $1.2 million in full, together with accrued interest of $0.2 million thereon, in the three months ended June 30, 2020, following a review of the value of the Company’s investments that confirmed the historical impairment in value undertaken in 2005 was appropriate.
The Company and its U.S. subsidiaries remain open to examination by the IRS for years 2016 onwards under the statute of limitations. The Company’s subsidiaries in foreign tax jurisdictions are open to examination including Germany (2015 onwards), Switzerland (2015 onwards), Spain (2016 onwards), France (2017 onwards) and the United Kingdom (2018 onwards).

NOTE 10 – PLANT CLOSURE PROVISIONS
The Company has continuing plans to close some of its manufacturing facilities at sites around the world as and when those operations are expected to be decommissioned. The liability for estimated closure costs of Innospec’s manufacturing facilities includes costs for decontamination and environmental remediation activities (“remediation”).
As a result, the principal site giving rise to remediation liabilities is the manufacturing site at Ellesmere Port in the United Kingdom. There are also remediation liabilities on a much smaller scale in respect of our other manufacturing sites in the U.S. and Europe.

The following methods and assumptions were used to estimate the fair values of financial instruments:
Cash and cash equivalents:
The carrying amount approximates fair value because of the short-term maturities of such instruments.
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.
Long-term debt and finance leases:
Long-term debt comprises the revolving credit facility, which is shown net of deferred finance costs that have been capitalized. Finance leases relate to certain fixed assets in our Fuel Specialties and Oilfield Services segments. The carrying amount of long-term debt and 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.

NOTE 12 – 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 June 30, 2020 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 six months of 2020 was a gain of $1.8 million (first six months of 2019: gain of $1.0 million).
As at June 30, 2020 and December 31, 2019 the Company did not hold any interest rate swaps. In prior years, the Company entered into interest rate swaps to minimize interest rate exposure related to a portion of its borrowing requirements. These interest rate swaps were designated as hedging instruments, and their impact on accumulated other comprehensive loss for the first six months of 2019 was a loss of $1.5 million.

NOTE 13 – COMMITMENTS AND 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 June 30, 2020, such guarantees which are not recognized as liabilities in the condensed consolidated financial statements amounted to $4.9 million (December 31, 2019 - $4.7 million). The remaining terms of the fixed maturity guarantees vary from 1 month to 4 years, 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 fulfill 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.
