PART I

Item 1 Business

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.

General

Innospec develops, manufactures, blends, markets and supplies fuel additives, oilfield chemicals, personal care and fragrance ingredients and other specialty chemicals. Our products are sold primarily to oil and gas exploration and production companies, oil refineries, personal care and fragrance companies, and other chemical and industrial companies throughout the world. Our fuel additives help improve fuel efficiency, boost engine performance and reduce harmful emissions. Our oilfield specialties business supplies drilling and production chemicals which make exploration and production more cost-efficient and more environmentally-friendly. Our other specialty chemicals provide effective technology-based solutions for our customers’ processes or products focused in the Personal Care; Polymers; and Fragrance Ingredients markets. Our Octane Additives business manufactures products for use in automotive gasoline and provides services in respect of environmental remediation.

Segmental Information

Innospec divides its business into three segments for management and reporting purposes:

• Fuel Specialties

• Performance Chemicals

• Octane Additives

The Fuel Specialties and Performance Chemicals segments operate in markets where we actively seek growth opportunities although their ultimate customers are different. The Octane Additives segment is generally characterized by volatile and declining demand. For financial information about each of our segments, see Note 3 of the Notes to the Consolidated Financial Statements.

Fuel Specialties

Our Fuel Specialties segment develops, manufactures, blends, markets and supplies a range of specialty chemical products used as additives to a wide range of fuels. These fuel additive products help improve fuel efficiency, boost engine performance and reduce harmful emissions; and are used in the efficient operation of automotive, marine and aviation engines, power station generators, and heating and diesel particulate filter systems. Our Fuel Specialties segment also includes our activities in the oilfield specialties sector.

4

During 2014, we completed the acquisition of Independence Oilfield Chemicals LLC (“Independence”), as part of our strategy of building a new market leader in the oilfield specialties sector.

In addition to our recent acquisitions in the oilfield specialties sector, the segment has grown organically through our development of new products to address what we believe are the key drivers in demand for fuel additives. These drivers include increased focus on fuel economy, changing engine technology and legislative developments. We have also devoted substantial resources towards the development of new and improved products that may be used to improve fuel efficiency.

Our customers in this segment include national oil companies, multinational oil companies, oil and gas exploration and production companies and fuel retailers.

Performance Chemicals

Our Performance Chemicals segment provides effective technology-based solutions for our customers’ processes or products focused in the Personal Care; Polymers; and Fragrance Ingredients markets.

This segment has also grown organically, through the development and marketing of innovative products to the personal care industry. The focus for our Performance Chemicals segment is to develop high performance products from its technology base in a number of targeted markets.

Our customers in this segment include large multinational companies, manufacturers of personal care and household products and specialty chemical manufacturers operating in niche industries.

Octane Additives

Our Octane Additives segment, which we believe is the world’s only producer of tetra ethyl lead (“TEL”), comprises sales of TEL for use in automotive gasoline and provides services in respect of our environmental remediation business. We are continuing to responsibly manage the decrease in the sales of TEL for use in automotive gasoline in line with the transition plans to unleaded gasoline of other remaining TEL countries. Cost improvement measures continue to be taken to respond to declining market demand.

Sales of TEL for use in automotive gasoline are made principally to state-owned refineries located in Northern Africa. Our environmental remediation business manages the cleanup of redundant TEL plants as refineries complete the move away from leaded gasoline.

Strategy

Our strategy is to develop new and improved products and technologies to continue to strengthen and increase our market positions within our Fuel Specialties and Performance

5

Chemicals segments. The segments together have had average organic revenue growth of 6% per annum, and average operating income growth of 6% per annum, since 2009. We also actively continue to assess potential strategic acquisitions, partnerships and other opportunities that would enhance and expand our customer offering. We focus on opportunities that would extend our technology base, geographical coverage or product portfolio. We believe that focusing on the Fuel Specialties and Performance Chemicals segments, in which the Company has existing experience, expertise and knowledge, provides opportunities for positive returns on investment with reduced operating risk. We also continue to develop our geographical footprint, consistent with the development of global markets.

Geographical Area Information

Financial information with respect to our domestic and foreign operations is contained in Note 3 of the Notes to the Consolidated Financial Statements.

Working Capital

The nature of our customers’ businesses generally requires us to hold appropriate amounts of inventory in order to be able to respond quickly to customers’ needs. We therefore require corresponding amounts of working capital for normal operations. We do not believe that this is materially different to what our competitors do (with the exception of cetane number improvers, in which case we maintain high enough levels of inventory, as required, to retain our position as market leader in sales of these products).

The purchase of large amounts of certain raw materials for our Fuel Specialties and Octane Additives segments can create some variations in working capital requirements, but these are planned and well managed by the business.

We do not believe that our terms of sale, or purchase, differ markedly from those of our competitors.

Raw Materials and Product Supply

We use a variety of raw materials and chemicals in our manufacturing and blending processes and believe that sources for these are adequate for our current operations. Our major purchases are cetane number improvers, Octane enhancers, Ethylene and various solvents.

These purchases account for a substantial portion of the Company’s variable manufacturing costs. These materials are, with the exception of Ethylene for our operations in Germany, readily available from more than one source. Although Ethylene is, in theory, available from several sources, it is not permissible to transport Ethylene by road in Germany. As a result, we source Ethylene for our German operations via a direct pipeline from a neighboring site, making it effectively a single source. Ethylene is used as a primary raw material in products representing approximately 6% of the Company’s sales.

6

We use long-term contracts (generally with fixed or formula-based costs) and advance bulk purchases to help ensure availability and continuity of supply, and to manage the risk of cost increases. From time to time, for some raw materials the risk of cost increases is managed with commodity swaps.

We continue to monitor the situation and adjust our procurement strategies as we deem appropriate. The Company forecasts its raw material requirements substantially in advance, and seeks to build long-term relationships and contractual positions with supply partners to safeguard its raw material positions. In addition, the Company operates an extensive risk management program which seeks to source key raw materials from multiple sources and to develop suitable contingency plans.

Intellectual Property

Our intellectual property, including trademarks, patents and licenses, forms a significant part of the Company’s competitive advantage, particularly in the Fuel Specialties and Performance Chemicals segments. The Company does not, however, consider its business as a whole to be dependent on any one trademark, patent or license.

The Company has a portfolio of trademarks and patents, both granted and in the application stage, covering products and processes in several jurisdictions. The majority of these patents were developed by the Company and, subject to maintenance obligations including the payment of renewal fees, have at least 10 years life remaining.

The trademark “Innospec and the Innospec device” in Classes 1, 2 and 4 of the “International Classification of Goods and Services for the Purposes of the Registration of Marks” are registered in all jurisdictions in which the Company has a significant market presence. The Company also has trademark registrations for certain product names in all jurisdictions in which it has a significant market presence.

We actively protect our inventions, new technologies, and product developments by filing patent applications and maintaining trade secrets. In addition, we vigorously participate in patent opposition proceedings around the world where necessary to secure a technology base free from infringement of our intellectual property.

Customers

In 2014, the Company had as a significant customer in the Fuel Specialties segment, Royal Dutch Shell plc and its affiliates (“Shell”), which accounted for $81.9 million (8.5%) of our net group sales. In 2013 and 2012, Shell accounted for $83.1 million (10%) and $82.9 million (11%) of our net group sales, respectively.

We have sales contracts with customers in some markets using fixed or formula-based prices, as appropriate, to maintain our gross profits.

7

Competition

Certain markets in which the Company operates are subject to significant competition. The Company competes on the basis of a number of factors including, but not limited to, product quality and performance, specialized product lines, customer relationships and service, and regulatory and toxicological expertise.

Fuel Specialties: The Fuel Specialties market is generally fragmented and characterized by a small number of competitors in each submarket. The competitors in each submarket differ with no one company holding a dominant position in the Fuel Specialties market. Within the Fuel Specialties market, the oilfield specialties sub-market is also very fragmented – although there are a small number of very large competitors, there are also a large number of smaller players focused on specific technologies or regions. We consider our competitive edge to be our proven technical development capacity, independence from major oil companies and strong long-term relationships with refinery customers.

Performance Chemicals: We operate in three principal markets within Performance Chemicals – Personal Care; Polymers; and Fragrance Ingredients. The Personal Care market is highly fragmented, and the Company experiences substantial competition from a large number of multinational and specialty chemical suppliers in each geographical market. The Fragrance Ingredients and Polymers markets are more concentrated, with a small number of principal competitors. Our competitive position in all three markets is based on us supplying a superior, diverse product portfolio which solves particular customer problems or enhances the performance of new or existing products. In a number of specialty chemicals markets, we also supply niche product lines, where we enjoy market-leading positions.

Octane Additives: We believe our Octane Additives segment is the world’s only producer of TEL and accordingly is the only supplier of TEL for use in automotive gasoline. The segment therefore competes with marketers of products and processes that provide alternative ways of enhancing octane performance in automotive gasoline.

Research, Development, Testing and Technical Support

Research, product/application development and technical support (“R&D”) provide the basis for the growth of our Fuel Specialties and Performance Chemicals segments. Accordingly, the Company’s R&D activity has been, and will continue to be, focused on the development of new products and formulations. Our R&D department provides technical support for all of our reporting segments. Expenditures to support R&D services were $22.2 million, $21.2 million and $19.6 million in 2014, 2013 and 2012, respectively.

We believe that our proven technical capabilities provide us with a significant competitive advantage. In the last five years, the Fuel Specialties segment has developed new detergent, cold flow, stabilizers, anti-foulants, lubricity and combustion improver products, in addition to the introduction of many new cost effective fuel additive packages. This proven technical capability has also been instrumental in enabling us to produce innovative new products within our Performance Chemicals segment including Iselux^™ and Statsafe^®.

Health, Safety and Environmental Matters

We are subject to environmental laws in the majority of the countries in which we conduct business. Management believes that the Company is in material compliance with applicable environmental laws and has made the necessary provisions for the continued costs of compliance with environmental laws, including where appropriate asset retirement obligations.

Our principal site giving rise to environmental remediation liabilities is the Octane Additives manufacturing site at Ellesmere Port in the United Kingdom. There are also environmental remediation liabilities on a much smaller scale in respect of our other manufacturing sites in the U.S. and Europe. At Ellesmere Port there is a continuing asset retirement program related to certain manufacturing units that have been closed.

We recognize environmental liabilities when they are probable and costs can be reasonably estimated, and asset retirement obligations when there is a legal obligation and costs can be reasonably estimated. This involves anticipating the program of work and the associated future expected costs, and so involves the exercise of judgment by management. We regularly review the future expected costs of remediation and the current estimate is reflected in Note 12 of the Notes to the Consolidated Financial Statements.

The European Union legislation known as the Registration, Evaluation and Authorization of Chemical Substances Regulations (“REACH”) requires most of the Company’s products to be registered with the European Chemicals Agency. Under this legislation the Company has to demonstrate that its products are appropriate for their intended purposes. During this registration process, the Company incurs expense to test and register its products. The Company estimates that the cost of complying with REACH will be approximately $3 million over the next three years.

Employees

The Company had approximately 1300 employees in 20 countries as at December 31, 2014 (1100 employees in 20 countries as at December 31, 2013).

Available Information

Item 1A Risk Factors

The factors described below represent the principal risks associated with our business.

We are subject to extensive regulation of our international operations that could adversely affect our business and results of operations.

Due to our global operations, we are subject to many laws governing international commercial activity, conduct and relations, including those that prohibit improper payments to government officials, restrict where and with whom we can do business, and limit the products, software and technology that we can supply to certain countries and customers. These laws include but are not limited to, the U.S. Foreign Corrupt Practices Act and United Kingdom Bribery Act, sanctions and assets control programs administered by the U.S. Department of the Treasury and/or the European Union from time to time, and the U.S. export control laws such as the regulations under the U.S. Export Administration Act, as well as similar laws and regulations in other countries relevant to our business operations. Violations of any of these laws or regulations, which are often complex in their application, may result in criminal or civil penalties that could have a material adverse effect on our results of operations, financial position and cash flows.

We may not be able to consummate, finance or successfully integrate future acquisitions, partnerships or other opportunities into our business, which could hinder our strategy or result in unanticipated expenses and losses.

Part of our strategy is to pursue strategic acquisitions, partnerships and other opportunities to complement and expand our existing business. The success of these transactions depends on our ability to efficiently complete transactions, integrate assets and personnel acquired in these transactions and apply our internal control processes to these acquired businesses. Consummating acquisitions, partnerships or other opportunities and integrating an acquisition involve considerable expenses, resources and management time commitments, and our failure to effect these as intended could result in unanticipated expenses and losses. Post-acquisition integration may result in unforeseen difficulties and may deplete significant financial and management resources that could otherwise be available for the ongoing development or expansion of existing operations. Furthermore, we may not realize the benefits of an acquisition in the way we anticipated when we first entered the transaction. Any of these risks could adversely impact our results of operations, financial position and cash flows.

Competition and market conditions may adversely affect our operating results.

In certain markets, our competitors are larger than us and may have greater access to financial, technological and other resources. As a result, competitors may be better able to adapt to changes in conditions in our industries, fluctuations in the costs of raw materials or changes in global economic conditions. Competitors may also be able to introduce new products with enhanced features that may cause a decline in the demand and sales of our products. Consolidation of customers or competitors, or economic problems of customers in our markets

10

could cause a loss of market share for our products, place downward pressure on prices, result in payment delays or non-payment, or declining plant utilization rates. These risks could adversely impact our results of operations, financial position and cash flows.

We could be adversely affected by technological changes in our industry.

Our ability to maintain or enhance our technological capabilities, develop and market products and applications that meet changing customer requirements, and successfully anticipate or respond to technological changes in a cost effective and timely manner will likely impact our future business success. We compete on a number of fronts including, but not limited to, product quality and performance. In the case of some of our products, our competitors are larger than us and may have greater access to financial, technological and other resources. Our inability to maintain a technological edge, innovate and improve our products could cause a decline in the demand and sales of our products, and adversely impact our results of operations, financial position and cash flows.

Our reliance on a small number of significant customers may have a material adverse impact on our results of operations.

Our principal customers are major multinational and state-owned oil companies, and large multinational manufacturers of personal care and household products. These industries are characterized by a concentration of a few large participants. The loss of a significant customer, a material reduction in demand by a significant customer or termination or non-renewal of a significant customer contract could adversely impact our results of operations, financial position and cash flows.

We may be required to make additional cash contributions to our United Kingdom defined benefit pension plan and recognize greater pension charges.

Movements in the underlying plan asset value and Projected Benefit Obligation (“PBO”) of our United Kingdom defined benefit pension plan are dependent on actual return on investments as well as our assumptions in respect of the discount rate, annual member mortality rates, future return on assets and future inflation. A change in any one of these assumptions could impact the plan asset value, PBO and pension charge recognized in the income statement. If future plan investment returns prove insufficient to meet future obligations, or should future obligations increase due to actuarial factors or changes in pension legislation, then we may be required to make additional cash contributions. These events could adversely impact our results of operations, financial position and cash flows.

Our success depends on our management team and other key personnel, the loss of any of whom could disrupt our business operations.

Our future success will depend in substantial part on the continued services of our senior management. The loss of the services of one or more of our key executive personnel could affect implementation of our business plan and result in reduced profitability. Our future success

11

also depends on the continued ability to attract, retain and motivate highly-qualified technical, sales and support staff. We cannot guarantee that we will be able to retain our key personnel or attract or retain qualified personnel in the future. If we are unsuccessful in our efforts in this regard, this could adversely impact our results of operations, financial position and cash flows.

Continuing adverse global economic conditions could materially affect our current and future businesses.

The ongoing concern about the stability of global markets generally and the strength of counterparties in particular has led many lenders and institutional investors to reduce, or cease to provide, credit to businesses and consumers. These factors have led to a substantial and continuing decrease in spending by businesses and consumers, and a corresponding decrease in global infrastructure spending which could affect our business. Global economic factors affecting our business include, but are not limited to, geopolitical instability in some markets, miles driven by passenger and commercial vehicles, legislation to control fuel quality, impact of alternative propulsion systems, consumer demand for premium personal care and cosmetic products, and oil and gas drilling and production rates. The availability, cost and terms of credit have been, and may continue to be, adversely affected by the foregoing factors and these circumstances have produced, and may in the future result in, illiquid markets and wider credit spreads, which may make it difficult or more expensive for us to obtain credit. Turbulence in the U.S. and international markets and economies, a general restricted environment for credit, and a prolonged decline in business and consumer spending could adversely impact our results of operations, financial position and cash flows.

An information technology system failure may adversely affect our business.

We rely on information technology systems to transact our business. Like other global companies, we have, from time to time, experienced threats to our data and systems. Although we have implemented administrative and technical controls and take protective actions to reduce the risk of cyber incidents and protect our information technology, and we endeavor to modify such procedures as circumstances warrant, such measures may be insufficient to prevent physical and electronic break-ins, cyber-attacks or other security breaches to our computer systems. While to date we have not experienced a material cyber security breach, our systems, processes, software and network still may be vulnerable to internal or external security breaches, computer viruses, malware or other malicious code or cyber-attack, catastrophic events, power interruptions, hardware failures, fire, natural disasters, human error, system failures and disruptions, and other events that could have security consequences. Such an information technology failure or disruption could prevent us from being able to process transactions with our customers, operate our manufacturing facilities, and properly report those transactions in a timely manner. A significant, protracted information technology system failure may result in a material adverse effect on our results of operations, financial position and cash flows.

In 2014 we continued with the process of developing our new, company-wide, information system platform. We implemented the new platform at the majority of our U.S. sites in the third

12

quarter of 2013. Our next phase of implementation includes the majority of reporting units outside of the U.S. and is planned for the fourth quarter of 2015. Implementation costs may be more than projected or the new information system may not perform as expected, either of which could adversely impact our results of operations, financial position and cash flows.

We may have additional tax liabilities.

We are subject to income and other taxes in the U.S. and other jurisdictions. Significant judgment is required in estimating our worldwide provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. Although we believe our tax estimates are reasonable, any final determination pursuant to tax audits and any related litigation could be materially different to what is reflected in our consolidated financial statements. Should any tax authority disagree with our estimates and determine any additional tax liabilities for us, this could adversely impact our results of operations, financial position and cash flows.

We are exposed to fluctuations in foreign currency exchange rates, which may adversely affect our results of operations.

We generate a portion of our revenues and incur some operating costs in currencies other than the U.S. dollar. In addition, the financial position and results of operations of some of our overseas subsidiaries are reported in the relevant local currency and then translated to U.S. dollars at the applicable currency exchange rate for inclusion in our consolidated financial statements. Fluctuations in these currency exchange rates affect the recorded levels of our assets and liabilities, and our results of operations.

The primary exchange rate fluctuation exposures we have are with the European Union euro, British pound sterling and Swiss franc. Exchange rates between these currencies and the U.S. dollar have fluctuated significantly in recent years and may continue to do so. We cannot accurately predict future exchange rate variability among these currencies or relative to the U.S. dollar. While we take steps to manage currency exchange rate exposure, including entering into hedging transactions, we cannot eliminate all exposure to future exchange rate variability. These exchange risks could adversely impact our results of operations, financial position and cash flows.

Sharp and unexpected fluctuations in the cost of our raw materials and energy could adversely affect our profit margins.

We use a variety of raw materials, chemicals and energy in our manufacturing and blending processes. Many of these raw materials are derived from petrochemical-based feedstocks which can be subject to periods of rapid and significant cost instability. These fluctuations in cost can be caused by political instability in oil producing nations and elsewhere, or other factors influencing global supply and demand of these materials, over which we have little or no control. We use long-term contracts (generally with fixed or formula-based costs) and advance bulk purchases to help ensure availability and continuity of supply, and to manage the risk of cost increases. We have entered into hedging arrangements for certain utilities and raw

13

materials, but do not typically enter into hedging arrangements for all raw materials, chemicals or energy costs. If the costs of raw materials, chemicals or energy increase, and we are not able to pass on these cost increases to our customers, then profit margins and cash flows from operating activities would be adversely impacted. If raw material costs increase significantly, then our need for working capital could increase. Any of these risks could adversely impact our results of operations, financial position and cash flows.

Trends in oil prices affect the level of exploration, development, and production activity of our customers and the demand for our services and products, which could have a material adverse impact on our business.

Demand for our services and products in our oilfield specialties business is particularly sensitive to the level of exploration, development, and production activity of, and the corresponding capital spending by oil companies. The level of exploration, development, and production activity is directly affected by trends in oil prices, which historically have been volatile and are likely to continue to be volatile. Prices for oil are subject to large fluctuations in response to relatively minor changes in the supply of and demand for oil, market uncertainty, and a variety of other economic factors that are beyond our control. Even the perception of longer-term lower oil prices by oil companies can similarly reduce or defer major expenditures given the long-term nature of many large-scale development projects. Factors affecting the prices of oil include the level of supply and demand for oil, governmental regulations, including the policies of governments regarding the exploration for and production and development of their oil reserves, weather conditions and natural disasters, worldwide political, military, and economic conditions, the level of oil production by non-OPEC countries and the available excess production capacity within OPEC, the cost of producing and delivering oil and potential acceleration of the development of alternative fuels. Any prolonged reduction in oil prices will depress the immediate levels of exploration, development, and production activity which could adversely impact our results of operations, financial position and cash flows.

A disruption in the supply of raw materials or transportation services would have a material adverse impact on our results of operations.

Although we try to anticipate problems with supplies of raw materials or transportation services by building certain inventories of strategic importance, any significant disruption in either area could affect our ability to obtain raw materials or transportation services at affordable costs, if at all, which could adversely impact our results of operations, financial position and cash flows.

Our reliance on a small number of significant stockholders may have a material adverse impact on our stock price.

Approximately 55% of our common stock is held by six stockholders. A decision by any of these stockholders to sell all or a significant part of its holding, or a sudden or unexpected disposition of our stock, could result in a significant decline in our stock price which could in turn adversely impact our ability to access equity markets which in turn could adversely impact our results of operations, financial position and cash flows.

14

We face risks related to our foreign operations that may adversely affect our business.

We serve global markets and operate in certain countries with political and economic instability, including the Middle East, Northern Africa, Asia-Pacific, Eastern Europe and South America regions. Our international operations are subject to numerous international business risks including, but not limited to, geopolitical and economic conditions, risk of expropriation, import and export restrictions, exchange controls, national and regional labor strikes, high or unexpected taxes, government royalties and restrictions on repatriation of earnings or proceeds from liquidated assets of overseas subsidiaries. Any of these could adversely impact our results of operations, financial position and cash flows.

Failure to protect our intellectual property rights could adversely affect our future performance and cash flows.

Failure to maintain or protect our intellectual property rights may result in the loss of valuable technologies, or us having to pay other companies for infringing on their intellectual property rights. Measures taken by us to protect our intellectual property may be challenged, invalidated, circumvented or rendered unenforceable. We may also face patent infringement claims from our competitors which may result in substantial litigation costs, claims for damages or a tarnishing of our reputation even if we are successful in defending against these claims, which may cause our customers to switch to our competitors. Any of these events could adversely impact our results of operations, financial position and cash flows.

Our products are subject to extensive government scrutiny and regulation.

We are subject to regulation by federal, state, local and foreign government authorities. In some cases, we need government approval of our products, manufacturing processes and facilities before we may sell certain products. Many products are required to be registered with the U.S. Environmental Protection Agency and with comparable government agencies in the European Union and elsewhere. We are also subject to ongoing reviews of our products, manufacturing processes and facilities by government authorities, and must also produce product data and comply with detailed regulatory requirements.

In order to obtain regulatory approval of certain new products we must, among other things, demonstrate that the product is appropriate and effective for its intended uses, and that we are capable of manufacturing the product in accordance with applicable regulations. This approval process can be costly, time consuming, and subject to unanticipated and significant delays. We cannot be sure that necessary approvals will be granted on a timely basis or at all. Any delay in obtaining, or any failure to obtain or maintain, these approvals would adversely affect our ability to introduce new products and to generate income from those products. New or stricter laws and regulations may be introduced that could result in additional compliance costs and prevent or inhibit the development, manufacture, distribution and sale of our products. Such outcomes could adversely impact our results of operations, financial position and cash flows.

Legal proceedings and other claims could impose substantial costs on us.

We are from time to time involved in legal proceedings that result from, and are incidental to, the conduct of our business, including employee and product liability claims. Although we

15

maintain insurance to protect us against a variety of claims, if our insurance coverage is not adequate to cover such claims, then our results of operations, financial position and cash flows could be adversely affected if we are required to pay directly for such liabilities.

Environmental liabilities and compliance costs could have a substantial adverse impact on our results of operations.

We operate a number of manufacturing sites and are subject to extensive federal, state, local and foreign environmental, health and safety laws and regulations, including those relating to emissions to the air, discharges to land and water, and the generation, handling, treatment and disposal of hazardous waste and other materials on these sites. We operate under numerous environmental permits and licenses, many of which require periodic notification and renewal, which is not automatic. New or stricter laws and regulations could increase our compliance burden or costs and adversely affect our ability to develop, manufacture, blend, market and supply products.

Our operations, and the operations of prior owners of our sites, pose the risk of environmental contamination which may result in fines or criminal sanctions being imposed or require significant amounts in remediation payments.

We anticipate that certain manufacturing sites may cease production over time and on closure, will require safely decommissioning and some environmental remediation. The extent of our obligations will depend on the future use of the sites that are affected and the environmental laws in effect at the time. We currently have made a decommissioning and remediation provision in our consolidated financial statements based on current known obligations, anticipated plans for sites and existing environmental laws. If there were to be unexpected or unknown contamination at these sites, or future plans for the sites or environmental laws change, then current provisions may prove inadequate, which could adversely impact our results of operations, financial position and cash flows.

The inability of counterparties to meet their contractual obligations could have a substantial adverse impact on our results of operations.

We sell products to oil refineries and chemical companies throughout the world. Credit limits, ongoing credit evaluation and account monitoring procedures are used to minimize bad debt risk. Collateral is not generally required. We have in place a credit facility with a syndicate of banks. We use derivatives, including interest rate swaps, commodity swaps and foreign currency forward exchange contracts, in the normal course of business to manage market risks. We enter into derivative instruments with a diversified group of major financial institutions in order to manage the exposure to non-performance of such instruments.

We remain subject to market and credit risks including the ability of counterparties to meet their contractual obligations and the potential non-performance of counterparties to deliver contracted commodities or services at the contracted price. The inability of counterparties to meet their contractual obligations could have an adverse impact on our results of operations, financial position and cash flows.

16

The terms of our credit facility may restrict our ability to incur additional indebtedness or to otherwise expand our business.

Our revolving credit facility contains restrictive clauses which may limit our activities, and operational and financial flexibility. We may not be able to borrow under the credit facility if an event of default under the terms of the facility occurs. An event of default under the credit facility includes a material adverse change to our assets, operations or financial condition, and certain other events. The credit facility also contains a number of restrictions that limit our ability, among 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 requires us to meet certain financial ratios, including ratios based on net debt to EBITDA and net interest expense to EBITDA. Net debt, net interest expense and EBITDA are non-GAAP measures of liquidity defined in the credit facility. Our ability to meet these financial covenants depends upon the future successful operating performance of the business. If we fail to comply with financial covenants, we would be in default under the credit facility and the maturity of our outstanding debt could be accelerated unless we were able to obtain waivers from our lenders. If we were found to be in default under the credit facility, it could adversely impact our results of operations, financial position and cash flows.

Our business is subject to the risk of manufacturing disruptions, the occurrence of which would adversely affect our results of operations.

We are subject to hazards common to chemical manufacturing, blending, storage, handling and transportation including fires, labor strikes or slowdowns, explosions, mechanical failure in scheduled downtime, extreme weather, transportation interruptions, remediation, chemical spills and the release or discharge of toxic or hazardous substances. These hazards could result in loss of life, property damage, environmental contamination and temporary or permanent manufacturing cessation. Any of these factors could adversely impact our results of operations, financial position and cash flows.

Domestic or international natural disasters or terrorist attacks may disrupt our operations, decrease the demand for our products or otherwise have an adverse impact on our business.

Chemical related assets, and U.S. corporations such as us, may be at greater risk of future terrorist attacks than other possible targets in the U.S., the United Kingdom and throughout the world. Extraordinary events such as natural disasters may negatively affect local economies, including those of our customers or suppliers. The occurrence of such events cannot be predicted, but they can adversely impact economic conditions in general and in our specific markets. The resulting damage from such events could include loss of life, property damage or site closure. Any of these matters could adversely impact our results of operations, financial position and cash flows.

Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations

This discussion should be read in conjunction with our consolidated financial statements and the notes thereto.

EXECUTIVE OVERVIEW

Our business performance in 2014 grew in line with our expectations, as we delivered on our strategy to expand our oilfield specialties business. Sales in our growth businesses of Fuel Specialties and Personal Care reflected the strength of our product portfolio and research and development pipeline in these markets, while the decline in Octane Additives was in line with the final stages of transition to unleaded gasoline.

We have managed our investments in capital equipment, working capital and recruitment of additional skilled personnel in line with these market factors. Our capital program and expenses during 2014 included the continued investment in a new information system platform, which we expect to add value to our business in future years. During 2014, we completed the acquisition of Independence Oilfield Specialties LLC to further build out our presence in this market.

CRITICAL ACCOUNTING ESTIMATES

Note 2 of the Notes to the Consolidated Financial Statements includes a summary of the significant accounting policies and methods used in the preparation of the consolidated financial statements.

Contingencies

We are subject to legal, regulatory and other proceedings and claims. The Company discloses information concerning contingent liabilities in respect of these claims and proceedings for which an unfavorable outcome is more than remote and the potential loss could materially impact our results of operations, financial position and cash flows. We recognize within selling, general and administrative expenses liabilities for these claims and proceedings when it is probable that the Company has incurred a loss based on an unfavorable outcome and the amount of the loss can be reasonably estimated and we endeavor to fairly present, in conjunction with the disclosures of these matters in our consolidated financial statements, management’s view of our exposure. We review outstanding claims and proceedings with external counsel as appropriate to assess probability and estimates of loss. When the reasonable estimate is a range, the recognized liability will be the best estimate within the range. If no amount in the range is a better estimate than any other amount then the minimum amount of the range will be recognized.

We re-evaluate our assessments each quarter or as new and significant information becomes available. The actual cost of ultimately resolving a claim or proceeding may be significantly different from the amount of the recognized liability. In addition, because it is not permissible

24

to recognize a liability until the loss is both probable and estimable, in some cases there may be insufficient time to recognize a liability prior to the actual incurrence of the loss (upon verdict and judgment at trial, for example, or in the case of a quickly negotiated settlement).

Environmental Liabilities

Remediation provisions at December 31, 2014 amounted to $34.1 million and relate principally to our Ellesmere Port site in the United Kingdom. We recognize environmental liabilities when they are probable and costs can be reasonably estimated, and asset retirement obligations when there is a legal obligation and 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. The Company views the costs of vacating our Ellesmere Port site as contingent upon if and when it vacates the site because there is no present intention to do so. The Company has further determined that, due to the uncertain product life of TEL particularly in the market for aviation gasoline and other products being manufactured on site, there are uncertainties as to the probability and timing of the expected costs. Such uncertainties have been considered in estimating the provision.

Pensions

The Company maintains a defined benefit pension plan covering a number of its current and former employees in the United Kingdom. The Company also has other much smaller pension arrangements in the U.S. and overseas, but the obligations under those plans are not material. The United Kingdom plan is closed to future service accrual, but has a large number of deferred and current pensioners.

Movements in the underlying plan asset value and Projected Benefit Obligation (“PBO”) are dependent on actual return on investments as well as our assumptions in respect of the discount rate, annual member mortality rates, future return on assets and future inflation. A change in any one of these assumptions could impact the plan asset value, PBO and pension charge recognized in the income statement. Such changes could adversely impact our results of operations and financial position. For example, a 0.25% change in the discount rate assumption would change the PBO by approximately $29 million and the net pension credit for 2015 by approximately $0.3 million. A 0.25% change in the level of price inflation assumption would change the PBO by approximately $22 million and the net pension credit for 2015 would not be significantly changed.

Further information is provided in Note 9 of the Notes to the Consolidated Financial Statements.

Deferred Tax and Uncertain Income Tax Positions

At December 31, 2014, no valuation allowance is required against our foreign tax credit carry forwards within deferred tax as management believes that all the foreign tax credit carry forwards can be utilized in future periods prior to their expiration.

25

No deferred taxes have been provided for on the unremitted earnings of our overseas subsidiaries as any tax basis differences relating to investments in these overseas subsidiaries are considered to be permanent in duration. We have no current intention to repatriate past or future earnings of our overseas subsidiaries and consider that these earnings have been reinvested overseas. If circumstances were to change that would cause these earnings to be repatriated an additional U.S. tax liability could be incurred, and we continue to monitor this position.

The calculation of our tax liabilities involves evaluating uncertainties in the application of complex tax regulations. We recognize liabilities for anticipated tax audit issues based on our estimate of whether, and the extent to which, additional taxes will be required. If we ultimately determine that payment of these amounts is unnecessary, we reverse the liability and recognize a tax benefit during the period in which we determine that the liability is no longer necessary.

We also recognize tax benefits to the extent that it is more likely than not that our positions will be sustained, based on technical merits, when challenged by the taxing authorities. To the extent that we prevail in matters for which liabilities have been established, or are required to pay amounts in excess of our liabilities, our effective tax rate in a given period may be materially affected. An unfavorable tax settlement may require cash payments and result in an increase in our effective tax rate in the year of resolution. A favorable tax settlement may be recognized as a reduction in our effective tax rate in the year of resolution. We report interest and penalties related to uncertain income tax positions as income taxes. For additional information regarding uncertain income tax positions see Note 10 of the Notes to the Consolidated Financial Statements.

Business combinations

The acquisition method of accounting requires that we recognize the assets acquired and liabilities assumed at their acquisition date fair values. Goodwill is measured as the excess of consideration transferred over the acquisition date net fair values of the assets acquired and the liabilities assumed.

The measurement of the fair values of assets acquired and liabilities assumed requires considerable judgment. Although independent appraisals may be used to assist in the determination of the fair values of certain assets and liabilities, those determinations 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.

26

While we use our best estimates and assumptions as part of the process to value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. During the measurement period, which occurs before finalization of the purchase price allocation, changes in assumptions and estimates that result in adjustments to the fair values of assets acquired and liabilities assumed will have a corresponding offset to goodwill. Subsequent adjustments will impact our consolidated statements of income.

Goodwill

The Company’s reporting units, the level at which goodwill is tested for impairment, are consistent with the reportable segments. 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 sufficiently distinguished, operationally and for financial reporting purposes, from the rest of the Company. The Company tests goodwill annually for impairment, or between years if events occur or circumstances change which suggest that an impairment may have occurred.

The Company performs its annual goodwill tests in respect of Fuel Specialties and Performance Chemicals as at December 31 each year. In reviewing for any impairment charge the fair values of the reporting segments are estimated using an after-tax cash flow methodology based on management’s best available estimates at that time. The key assumptions underpinning these calculations include future revenue growth, gross margins and the Company’s weighted average cost of capital. At December 31, 2014 we had $229.4 million and $46.7 million of goodwill relating to our Fuel Specialties and Performance Chemicals segments, respectively. Our annual impairment tests as of such date indicated no impairment because the estimated fair values of those reporting segments substantially exceeded the carrying values.

While we believe our assumptions for impairment tests are reasonable, they are subjective judgments, and it is possible that variations in any of the assumptions may result in materially different calculations of impairment charges, if any.

Property, Plant and Equipment and Other Intangible Assets (Net of Amortization)

At December 31, 2014 we had $80.8 million of property, plant and equipment and $181.1 million of other intangible assets (net of amortization), that are discussed in Notes 5 and 7 of the Notes to the Consolidated Financial Statements, respectively. These long-lived assets relate to all of our reporting segments and are being amortized or depreciated straight-line over periods of up to 16 years in respect of the other intangible assets and up to 25 years in respect of the property, plant and equipment.

We continually assess the markets and products related to these long-lived assets, as well as their specific carrying values, and have concluded that these carrying values, and amortization and depreciation periods, remain appropriate.

27

We also test these long-lived assets for any potential impairment when events occur or circumstances change which suggest that an impairment may have occurred. These types of events or changes in circumstances could include, but are not limited to:

• introduction of new products with enhanced features by our competitors;

• loss of, material reduction in purchases by, or non-renewal of a contract by, a significant customer;

• prolonged decline in business or consumer spending;

• sharp and unexpected rise in raw material, chemical or energy costs; and

• new laws or regulations inhibiting the development, manufacture, distribution or sale of our products.

In order to facilitate this testing 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 cash flows discounted at the Company’s weighted average cost of capital. If events occur or circumstances change it may cause a reduction in periods over which these long-lived assets are amortized or depreciated, or result in a non-cash impairment of a portion of their carrying value. A reduction in amortization or depreciation periods would have no effect on cash flows.

In 2014 we continued with the process of developing a new, company-wide, information system platform. The platform provider is well established in the market. The implementation is a phased, risk-managed, site deployment and follows a multistage user acceptance program with the existing platform providing a fallback position. We implemented the new platform at the majority of our U.S. sites in the third quarter of 2013. Our next phase of implementation includes the majority of reporting units outside of the U.S.. Internally developed software and other costs capitalized at December 31, 2014 were $27.8 million (2013 – $19.5 million). An amortization expense of $3.8 million was recognized in 2014 (2013 – $1.0 million) in selling, general and administrative expenses.

Net sales: the table below details the components which comprise the year on year change in net sales spread across the markets in which we operate:

Change (%)	Americas		EMEA		ASPAC		AvTel		Total
Volume		+7		-12		-5		+24		-3
Price and product mix		+6		+6		-4		-9		+4
Exchange rates		0		0		0		0		0
Acquisitions		+53		0		0		0		+19
		+66		-6		-9		+15		+20

Americas saw an increase in volumes as a result of higher demand, while benefiting from an improved price and product mix. Acquisitions in the Americas, relating to Bachman and Independence, generated additional sales compared to the prior year. EMEA volumes decreased from the prior year due to weaker trading conditions and the impact of government

30

sanctions related to Russia, partly offset by an improved price and product mix. Volumes were lower in ASPAC due to the loss of a contract in 2013 which offset increased underlying volumes, together with an adverse price and product mix as a result of lower sales of higher margin products. AvTel volumes were higher due to the timing of shipments to customers as opposed to any change in the long-term outlook for that market, while the price and product mix was negatively impacted by an adverse customer mix.

Gross margin: the year on year increase of 0.2 percentage points primarily reflected a mix of increased sales from higher margin products and a higher margin contribution from our oilfield specialties acquisitions.

Operating expenses: the year on year increase of 30%, or $26.2 million, was due to $20.8 million of additional costs for the Bachman businesses; $6.3 million of additional costs for the Independence business; a $1.4 million increase in bad debt provisions, excluding recent acquisitions; partly offset by a $1.0 million decrease in personnel-related compensation costs, primarily due to lower accruals for share-based compensation expense; a $0.8 million decrease in costs for our Strata business; and a $0.5 million decrease in other expenses.

Performance Chemicals

Net sales: the table below details the components which comprise the year on year change in net sales spread across the markets in which we operate:

Change (%)	Americas		EMEA		ASPAC		Total

Price and product mix		-1		-2		0		-1
Exchange rates		+1		+3		+2		+2
Acquisitions		+22		0		0		+10
		+18		+16		+12		+16

Volumes in the Americas were lower, primarily due to lower volumes in Fragrance Ingredients and for an industrial product partly offset by increased Personal Care volumes. Acquisitions in the Americas, relating to Chemsil and Chemtec, generated additional sales compared to the prior year. Volumes in EMEA were higher than the prior year, primarily due to higher volumes in Personal Care and Fragrance Ingredients, while negatively impacted by an adverse price and product mix. Higher volumes in ASPAC were driven by increases in Personal Care. All our markets benefited from favorable exchange rate movements year over year, driven primarily by a strengthening of the European Union euro and the British pound sterling against the U.S. dollar.

Gross margin: the year on year increase of 0.2 percentage points primarily reflected a richer sales mix driven by a greater proportion of sales from our Personal Care market, including our Chemsil business.

31

Operating expenses: the year on year increase of 27%, or $6.1 million, was primarily in respect of $5.2 million of additional costs for our Chemsil and Chemtec businesses, and a $0.9 million increase in other costs, partly driven by additional headcount in several locations.

Octane Additives

Net sales: the year on year decrease of 6% was primarily due to the timing of shipments and declining demand with our one remaining customer.

Gross margin: the year on year increase of 4.7 percentage points was primarily due to favorable manufacturing variances.

Operating expenses: the year on year decrease of $0.3 million was due to the efficient management of the cost base.

Other Income Statement Captions

Pension credit/(charge): is non-cash, and was a $3.3 million net charge in 2014 compared to $2.3 million net charge in 2013, primarily due to a higher interest cost on the projected benefit obligation.

Corporate costs: the year on year decrease of 11%, or $4.9 million, related to $2.8 million higher costs for amortization of the new information system platform; $1.3 million higher insurance claims; offset by $1.0 million lower personnel-related compensation costs, primarily due to lower accruals for share-based compensation expense together with accruals for the new cash-based long-term incentive plan; the release of a $0.8 million restructuring provision which is no longer required; and $7.2 million lower legal, professional and other expenses.

Impairment of Octane Additives segment goodwill: was $0.0 million in 2014 and $1.3 million in 2013, following the final impairment charge in the fourth quarter of 2013.

Other net income/(expense): other net income of $1.8 million primarily related to net gains of $3.4 million on foreign currency forward exchange contracts, partly offset by $1.6 million of losses on translation of net assets denominated in non-functional currencies in our European businesses. In 2013, other net income of $4.1 million primarily related to gains of $5.8 million on translation of net assets denominated in non-functional currencies in our European businesses, partly offset by net foreign exchange losses on foreign currency forward exchange contracts of $1.6 million.

Interest expense, net: was $3.4 million in 2014 and $1.9 million in 2013 due to the higher level of borrowing during 2014, used primarily to fund our acquisition activity in the second half of 2013.

Income taxes: the effective tax rate was 24.2% and 16.2% in 2014 and 2013, respectively. The effective tax rate, once adjusted for income tax provisions and for the tax impact of other discrete items, was 24.9% in 2014 compared with 15.9% in 2013. The Company believes that

32

this adjusted effective tax rate, a non-GAAP financial measure, provides useful information to investors and may assist them in evaluating the Company’s underlying performance and identifying operating trends. In addition, management uses this non-GAAP financial measure internally to evaluate the performance of the Company’s operations and for planning and forecasting in subsequent periods.

(in millions, except ratios)	2014			2013

In addition to those mentioned above, the following factors had a significant impact on the Company’s effective tax rate as compared to the U.S. federal income tax rate of 35%:

(in millions)	2014			2013
Foreign tax rate differential	$	(16.2	)	$	(13.6	)
Foreign income inclusions		6.0			3.9
Prior year adjustments	$	5.2		$	(2.7	)

The impact on the effective tax rate from profits earned in foreign jurisdictions with lower tax rates varies as the geographical mix of the Company’s profits changes year on year. In 2014, the Company’s income tax expense benefited to a greater degree from a proportion of its overall profits arising in Switzerland than in 2013. This resulted in a $9.4 million benefit in Switzerland (2013 – $9.3 million). In addition, there was a $7.9 million benefit in relation to the United Kingdom (2013 – $3.9 million) and a $0.4 million benefit in relation to Germany (2013 – $0.3 million).

Foreign income inclusions arise each year from certain types of income earned overseas being taxable under U.S. tax regulations. These types of income include Subpart F income, principally from foreign based company sales in the United Kingdom, including the associated Section 78 tax gross up, and also from the income earned by certain overseas subsidiaries taxable under the U.S. tax regime. In 2014, the amount of Subpart F income and the associated Section 78 gross up amounted to $5.0 million (2013 – $4.3 million). The income earned by certain overseas subsidiaries taxable under the U.S. tax regime increased to $2.1 million from $1.2 million in 2013.

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 in certain years prevent any offset of foreign tax credits. In total, $4.8 million of foreign tax credits were

33

utilized during 2014 to partially offset the incremental U.S. taxes arising from foreign income inclusions in the year (2013 – $4.2 million). Of this balance, $3.6 million of foreign tax credit carry forwards from earlier years was utilized (2013 – $2.4 million). This resulted in a decrease in the recognition of foreign tax credit carry forwards of $3.6 million during the year (2013 – a $2.4 million decrease).

Americas saw an increase in volumes in 2013 as a result of higher demand, offset by an adverse price and product mix as a result of lower sales of high margin products. Acquisitions in the Americas, relating to Strata and Bachman, generated additional sales compared to 2012. EMEA volumes remained on par with the prior year, while benefiting from an improved price and product mix. EMEA benefited from favorable exchange rates driven primarily by a strengthening of the European Union euro against the U.S. dollar. Volumes were higher in ASPAC with an adverse price and product mix as a result of lower sales of higher margin products. Avtel volumes increased due to the timing of shipments to customers as opposed to any change in the long-term outlook for that market with the price and product mix benefiting from a favorable customer mix.

Gross margin: the year on year increase of 1.8 percentage points reflected a richer price and product mix in EMEA; the continued benefit from higher margin sales in the Strata business; and a favorable customer mix in our higher margin Avtel business; which were offset by adverse price and product mix in the Americas and ASPAC.

Operating expenses: the year on year increase of 24%, or $17.3 million, was due to $6.7 million of additional costs for the Strata business; $3.4 million of additional costs for the Bachman businesses; $2.4 million of increased personnel-related compensation costs, partly due to the higher accruals for share based compensation expense driven by the rise in our stock price compared to the same period in the prior year; $2.9 million of additional research, development and new product testing costs; $1.4 million of additional commissions; and a $0.5 million increase in other expenses.

In the Americas volumes were lower in Fragrance Ingredients, partly offset by an improved price and product mix resulting from a retrospective price adjustment with a customer. Acquisitions in the Americas, relating to Chemsil and Chemtec, generated additional sales compared to 2012. Volumes in EMEA are on a par with the prior year, combined with a marginally weaker price and product mix in Fragrance Ingredients partially offset by improved sales mix in Personal Care. ASPAC volumes moved higher but were impacted by higher sales of lower margin products.

Gross margin: the year on year decrease of 0.3 percentage points reflected the competitive pricing pressures for Fragrance Ingredients, partly offset by a richer price and product mix in

35

our Personal Care market; together with a retrospective price adjustment with a customer in the Americas and EMEA; and higher margins in our Chemsil business.

Operating expenses: the year on year increase of 16%, or $3.2 million, reflected $3.1 million of additional costs for our recently acquired Chemsil and Chemtec businesses; $0.3 million higher personnel-related compensation costs driven by the rise in our stock price compared to the same period in the prior year; and a $0.2 million decrease in other expenses.

Octane Additives

Net sales: decreased by 15% with decreased volumes (down 18 percentage points), due to the timing of shipments and declining demand from major customers, and an improved customer mix (up 4 percentage points), together with reduced revenue from our environmental remediation business (down 1 percentage points). In both 2013 and 2012, sales were focused in the Middle East and Northern Africa.

Gross margin: decreased by 1.6 percentage points from 48.7% to 47.1%, due to lower manufacturing volumes, partly offset by favorable customer mix and non-recurring freight storage costs in the prior year.

Operating expenses: decreased by $1.6 million from $7.9 million to $6.3 million, due to the efficient management of the cost base.

Other Income Statement Captions

Pension credit/(charge): this non-cash charge increased to a $2.3 million net charge in 2013 compared to a $1.6 million net charge in 2012, after revising the amortization of actuarial losses in 2012. The increase in the net charge in 2013 primarily relates to increased actuarial net losses being amortized to the income statement.

Corporate costs: the year on year increase of 13%, or $5.0 million, reflected $8.3 million higher legal, compliance, professional and other expenses, including acquisition-related costs of $1.8 million in 2013 compared to $2.8 million in 2012; $1.8 million higher personnel-related compensation costs, primarily due to higher accruals for share based compensation expense, driven by the rise in our stock price compared to the same period in the prior year; $0.7 million higher information technology service platform costs; offset by a $5.8 million reduction in the charge for the long-term incentive plan which completed at the end of 2012.

Impairment of Octane Additives segment goodwill: was $1.3 million in 2013 and $1.2 million in 2012.

Other net income/(expense): other net income of $4.1 million primarily related to gains of $5.8 million on translation of net assets denominated in non-functional currencies in our European businesses, partly offset by net foreign exchange losses on foreign currency forward exchange contracts of $1.6 million. In 2012, other net expense of $2.0 million primarily related to losses on translation of net assets denominated in non-functional currencies in our European businesses offset by net foreign exchange gains on foreign currency forward exchange contracts.

36

Interest expense, net: increased to $1.9 million in 2013 from $1.2 million in 2012 due to the higher level of borrowing during 2013, used primarily to fund our acquisition activity.

Income taxes: the effective tax rate was 16.2% and 28.3% in 2013 and 2012, respectively. The effective tax rate, once adjusted for income tax provisions and for the tax impact of acquisition-related funding, was 15.9% in 2013 compared with 20.2% in 2012. The Company believes that this adjusted effective tax rate, a non-GAAP financial measure, provides useful information to investors and may assist them in evaluating the Company’s underlying performance and identifying operating trends. In addition, management uses this non-GAAP financial measure internally to evaluate the performance of the Company’s operations and for planning and forecasting in subsequent periods.

The impact on the effective tax rate from profits earned in foreign jurisdictions with lower tax rates varies as the geographical mix of the Company’s profits changes year on year. In 2013, the Company’s income tax expense benefited to a lesser degree from a proportion of its overall profits arising in Switzerland than in 2012. This resulted in a $9.3 million benefit in Switzerland (2012 – $12.0 million). In addition, there was a $3.9 million benefit in relation to the United Kingdom (2012 – $3.3 million) and a $0.3 million benefit in relation to Germany (2012 – $0.7 million).

Foreign income inclusions arise each year from certain types of income earned overseas being taxable under U.S. tax regulations. These types of income include Subpart F income, principally from foreign based company sales in the United Kingdom, including the associated Section 78 tax gross up, and also from the income earned by certain overseas subsidiaries

37

taxable under the U.S. tax regime. In 2013, the amount of Subpart F income and the associated Section 78 gross up amounted to $4.3 million (2012 – $4.3 million). The income earned by certain overseas subsidiaries taxable under the U.S. tax regime decreased to $1.2 million from $2.5 million in 2012. A dividend from an overseas subsidiary, remitted to the U.S., increased foreign income inclusions by $39.0 million during 2012. In 2013 no dividends were remitted to the U.S..

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 in certain years prevent any offset of foreign tax credits. In total, $4.2 million of foreign tax credits were utilized during 2013 to partially offset the incremental U.S. taxes arising from foreign income inclusions in the year (2012 – an overseas dividend was remitted to the U.S. to provide funding for the Company’s acquisition program and $42.8 million of foreign tax credits were utilized during 2012). Of this balance, $2.4 million of foreign tax credit carry forwards from earlier years was utilized (2012 – $14.2 million). This resulted in a decrease in the recognition of foreign tax credit carry forwards of $2.4 million during the year (2012 – a $6.6 million decrease).

The United Kingdom’s 3% reduction in the corporation tax rate from 23% to 20% in April 2015, enacted in July 2013, resulted in a net deferred tax charge of $0.9 million (2012 – a net deferred tax credit of $0.5 million) in the third quarter of 2013 primarily in relation to the deferred tax position of the United Kingdom defined benefit pension plan.

LIQUIDITY AND FINANCIAL CONDITION

Working Capital

The Company believes that adjusted working capital, a non-GAAP financial measure, provides useful information to investors in evaluating the Company’s underlying performance and identifying operating trends. Management uses this non-GAAP financial measure internally to allocate resources and evaluate the performance of the Company’s operations. Items excluded from the adjusted working capital calculation are listed in the table below and represent factors which do not fluctuate in line with the day to day working capital needs of the business.

Adjusted working capital	$	192.7		$	163.7

In 2014 our adjusted working capital increased by $29.0 million, primarily due to $28.9 million of working capital in the Independence business as at December 31, 2014.

We had a $28.5 million increase in trade and other accounts receivable in 2014, which is primarily related to the acquisition of Independence, partly offset by lower receivables in our Octane Additives segment due to the declining demand and the timing of shipments to our one remaining customer. Days’ sales outstanding in our Fuel Specialties segment increased from 49 days to 52 days and decreased from 51 days to 48 days in our Performance Chemicals segment.

We had a $26.0 million increase in inventories in 2014, which is primarily related to the acquisition of Independence, together with slightly higher inventories in our Fuel Specialties segment. Days’ sales in inventory in our Fuel Specialties segment decreased from 79 days to 76 days and increased in our Performance Chemicals segment from 96 days to 99 days.

39

Prepaid expenses increased $2.5 million from $5.8 million to $8.3 million, partly related to the acquisition of Independence.

We had a $28.0 million increase in accounts payable and accrued liabilities during 2014, which is primarily related to the acquisition of Independence. Creditor days in our Fuel Specialties segment increased from 32 days to 40 days and in our Performance Chemicals segment decreased from 42 days to 31 days.

Operating Cash Flows

We generated cash from operating activities of $106.3 million in 2014 compared to $61.3 million in 2013. Year over year cash from operating activities has been positively impacted by increased net income, after adding back increased amortization costs from the recent acquisitions, and significant movements in income taxes.

Cash

At December 31, 2014 and 2013, we had cash and cash equivalents of $41.6 million and $80.2 million, respectively, of which $30.1 million and $73.3 million, respectively, were held by non-U.S. subsidiaries principally in the United Kingdom. The Company is in a position to control whether or not to repatriate foreign earnings. We currently do not expect to make a repatriation in the foreseeable future and hence have not provided for future income taxes on the cash held by overseas subsidiaries. If circumstances were to change that would cause these earnings to be repatriated, an additional U.S. tax liability could be incurred, and we continue to monitor this position.

Short-term Investments

At December 31, 2014 and 2013, we had short-term investments of $4.7 million and $6.6 million, respectively.

Debt

On August 28, 2013, we amended our five-year revolving credit facility (“the facility”). The amendment provided for an increase in the facility available to the Company and certain subsidiaries of the Company from $100.0 million to $150.0 million and retains the term of the facility through to December 2016. In addition, an amendment allowed the Company to request an additional amount of $50.0 million to be committed by the lenders, of which $30.0 million was committed in the fourth quarter of 2013.

On July 31, 2014, the Company increased its borrowing capacity by $20.0 million such that its credit facility now provides for borrowings by us of up to $200.0 million until it expires on December 14, 2016 and may be drawn down in full in the U.S..

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

40

ratios measured on a quarterly basis: (1) our ratio of net debt to EBITDA must not be greater than 2.5:1 and (2) our ratio of EBITDA to net interest must not be less than 4.0:1. Management has determined that the Company has not breached these covenants throughout the period to December 31, 2014 and expects to not breach these covenants for the next 12 months. The credit facility is secured by a number of fixed and floating charges over certain assets which include key operating sites of the Company and its subsidiaries.

The current credit facility contains restrictions which may limit our activities, and operational and financial flexibility. We may not be able to borrow if an event of default is outstanding, which includes a material adverse change to our assets, operations or financial condition. The credit facility contains a number of restrictions that limit our ability, among other things, and subject to certain limited exceptions, to incur additional indebtedness, pledge our assets as security, guarantee obligations of third parties, make investments, effect a merger or consolidation, dispose of assets, or materially change our line of business.

At December 31, 2014, we had $139.0 million of debt outstanding under the revolving credit facility, $0.4 million of debt financing within our Independence business and $2.2m of obligations under finance leases relating to certain fixed assets within our Independence business.

At December 31, 2014, our maturity profile of long-term debt and finance leases is set out below:

(in millions)
2015	$	0.9
2016		140.1
2017		0.6
2018		0.0
Total debt		141.6
Current portion of long-term debt and finance leases		(0.9	)
Long-term debt and finance leases, net of current portion	$	140.7

Outlook

At December 31, 2014, the Company had cash, cash equivalents and short-term investments of $46.3 million, long-term debt of $139.4 million and finance leases of $2.2 million, giving total debt of $141.6 million, resulting in net debt of $95.3 million.

The Company expects to fund its operations over at least the next 12 months from a combination of operating cash flows and its revolving credit facility. The Company has funded the acquisition of Independence in 2014 with existing cash and debt facilities which the Company believes will continue to provide adequate sources of liquidity for future working capital needs.

Total	$	358.3	$	75.8	$	230.8	$	30.8	$	20.9

Operating activities

The amounts related to pension obligations refer to the likely levels of funding of our United Kingdom defined benefit pension plan (the “Plan”). The Plan is closed to future service accrual, but has a large number of deferred and current pensioners. The Company expects its annual cash contribution to be $10.8 million in 2015, $15.3 million in 2016-17 and $10.9 million in 2018-19. It is not considered meaningful to predict amounts beyond 2020 since there are too many uncertainties including future returns on assets, pension increases and inflation which are evaluated when the plan undertakes an actuarial valuation every three years.

Remediation payments represent those cash flows that the Company is currently obligated to pay in respect of environmental remediation of current and former facilities. It does not include any discretionary remediation costs that the Company may choose to incur.

Operating lease commitments relate primarily to office space, motor vehicles and various items of computer and office equipment which are expected to be renewed and replaced in the normal course of business.

Raw material purchase obligations relate to certain long-term raw material contracts which stipulate fixed or minimum quantities to be purchased; fixed, minimum or variable cost provisions; and the approximate timing of the transaction. Purchase obligations exclude agreements that are cancelable without penalty.

42

The estimated payments included in the table above reflect the variable interest charge on long-term debt obligations. Estimated commitment fees are also included and interest income is excluded.

Due to the uncertainty regarding the nature of tax audits, particularly those which are not currently underway, it is not meaningful to predict the outcome of obligations related to unrecognized tax benefits. Further disclosure is provided in Note 10 of the Notes to the Consolidated Financial Statements.

Investing activities

Capital commitments relate to certain capital projects that the Company has committed to undertake.

Financing activities

On December 14, 2011, we entered into a five-year revolving credit facility (“the facility”) which provides for borrowings of up to $100.0 million. The credit facility can be drawn down until it expires on December 14, 2016. On August 28, 2013, we amended the facility to increase the amount available to the Company and certain subsidiaries of the Company from $100.0 million to $150.0 million retaining the term and conditions of the facility through to December 2016. In addition, an amendment allowed the Company to request an additional amount of $50.0 million to be committed by the lenders, of which $30.0 million was committed in the fourth quarter of 2013.

On July 31, 2014 the Company increased its borrowing capacity by $20.0 million such that its credit facility now provides for borrowings by us of up to $200.0 million until it expires on December 14, 2016 and may be drawn down in full in the U.S..

Finance leases relate to the financing of certain fixed assets in our recent acquisition Independence Oilfield Chemicals LLC (“Independence”).

As part of the acquisition of Independence, Innospec has deferred consideration which is contingently payable over the next two years based on a multiple of Independence’s annualized earnings before interest, taxes, depreciation and amortization plus a percentage of free cash flow. Based on the current forecasts for Independence’s performance, Innospec will make two deferred consideration payments, with the first one being $45.7 million payable approximately one year after closing, and the second one being $49.5 million payable approximately two years after closing, with a portion of such deferred payments payable, at Innospec’s election, in shares of Innospec’s common stock.

Environmental Matters and Plant Closures

Under certain environmental laws the Company is responsible for the remediation of hazardous substances or wastes at currently or formerly owned or operated properties.

43

As most of our manufacturing operations have been conducted outside the U.S., we expect that liability pertaining to the investigation and remediation of contaminated properties is likely to be determined under non-U.S. law.

We evaluate costs for remediation, decontamination and demolition projects on a regular basis. Full provision is made for those costs to which we are committed under environmental laws amounting to $34.1 million at December 31, 2014. Remediation expenditure utilizing these provisions was $2.0 million, $1.9 million and $2.1 million in the years 2014, 2013 and 2012, respectively.

Item 7A Quantitative and Qualitative Disclosures About Market Risk

The Company uses floating rate debt to finance its global operations. The Company is subject to business risks inherent in non-U.S. activities, including political and economic uncertainty, import and export limitations, and market risk related to changes in interest rates and foreign currency exchange rates. The political and economic risks are mitigated by the stability of the countries in which the Company’s largest operations are located. Credit limits, ongoing credit evaluation and account monitoring procedures are used to minimize bad debt risk. Collateral is not generally required.

From time to time, the Company uses derivatives, including interest rate swaps, commodity swaps and foreign currency forward exchange contracts, in the normal course of business to manage market risks. The derivatives used in hedging activities are considered risk management tools and are not used for trading purposes. In addition, the Company enters into derivative instruments with a diversified group of major financial institutions in order to manage the exposure to non-performance of such instruments. The Company’s objective in managing the exposure to changes in interest rates is to limit the impact of such changes on earnings and cash flows and to lower overall borrowing costs. The Company’s objective in managing the exposure to changes in foreign currency exchange rates is to reduce volatility on earnings and cash flows associated with such changes.

The Company offers fixed prices for some long-term sales contracts. As manufacturing and raw material costs are subject to variability the Company uses commodity swaps to hedge the cost of some raw materials thus reducing volatility on earnings and cash flows. The derivatives are considered risk management tools and are not used for trading purposes. The Company’s objective is to manage its exposure to fluctuating costs of raw materials.

Interest Rate Risk

The Company uses interest rate swaps to manage interest rate exposure. As at December 31, 2014 the Company had cash, cash equivalents and short-term investments of $46.3 million, no bank overdraft and long-term debt of $139.4 million (including current portion). Long-term debt comprises a revolving credit facility which provides for borrowings by us of up to $200.0 million. The credit facility carries an interest rate based on U.S. dollar LIBOR plus a margin of between 1.50% and 2.25% which is dependent on the Company’s ratio of net debt to EBITDA. Net debt and EBITDA are non-GAAP measures of liquidity defined in the credit facility. At December 31, 2014, $139.0 million was drawn under the revolving credit facility. As management does not expect the credit facility to be drawn down in the long-term, the Company has not entered into interest rate swap agreements in relation to this.

The Company has $139.4 million long-term debt (including the current portion) which is partly offset by the $41.6 million cash and cash equivalents and $4.7 million short-term investments. Therefore, the interest payable on long-term debt (excluding the margin) exceeds the interest receivable on positive cash balances and short-term investments. On a gross basis,

45

assuming no additional interest on the cash balances and short-term investments, a hypothetical absolute change of 1% in U.S. base interest rates for a one-year period would impact net income and cash flows by approximately $1.4 million before tax. On a net basis, assuming additional interest on the cash balances and short-term investments, a hypothetical absolute change of 1% in U.S. base interest rates for a one-year period would impact net income and cash flows by approximately $0.9 million before tax.

The above does not consider the effect of interest or exchange rate changes on overall activity nor management action to mitigate such changes.

Exchange Rate Risk

The Company generates an element of its revenues and incurs some operating costs in currencies other than the U.S. dollar. The reporting currency of the Company is the U.S. dollar.

The Company evaluates the functional currency of each reporting unit according to the economic environment in which it operates. Several major subsidiaries of the Company operating outside of the U.S. have the U.S. dollar as their functional currency due to the nature of the markets in which they operate. In addition, the financial position and results of operations of some of our overseas subsidiaries are reported in the relevant local currency and then translated to U.S. dollars at the applicable currency exchange rate for inclusion in our consolidated financial statements.

The primary foreign currencies in which we have exchange rate fluctuation exposure are the European Union euro, British pound sterling and Swiss franc. Changes in exchange rates between these foreign currencies and the U.S. dollar will affect the recorded levels of our assets and liabilities, to the extent that such figures reflect the inclusion of foreign assets and liabilities which are translated into U.S. dollars for presentation in our consolidated financial statements, as well as our results of operations.

The Company’s objective in managing the exposure to foreign currency fluctuations is to reduce earnings and cash flow volatility associated with foreign currency exchange rate changes. Accordingly, the Company enters into various contracts that change in value as foreign currency exchange rates change to protect the U.S. dollar value of its existing foreign currency denominated assets, liabilities, commitments, and cash flows. The Company also uses foreign currency forward exchange contracts to offset a portion of the Company’s exposure to certain foreign currency denominated revenues so that gains and losses on these contracts offset changes in the U.S. dollar value of the related foreign currency denominated revenues. The objective of the hedging program is to reduce earnings and cash flow volatility related to changes in foreign currency exchange rates.

The trading of our Fuel Specialties and Performance Chemicals reporting segments is inherently naturally hedged and accordingly changes in exchange rates would not be material to our earnings or financial position. The cost base of our Octane Additives reporting segment

46

and corporate costs, however, are largely denominated in British pound sterling. A 5% strengthening in the U.S. dollar against British pound sterling would increase reported operating income by approximately $2.5 million for a one-year period excluding the impact of any foreign currency forward exchange contracts.

Where a 5% strengthening of the U.S. dollar has been used as an illustration, a 5% weakening would be expected to have the opposite effect on operating income.

Raw Material Cost Risk

We use a variety of raw materials, chemicals and energy in our manufacturing and blending processes. Many of the raw materials that we use are derived from petrochemical-based feedstocks which can be subject to periods of rapid and significant cost instability. These fluctuations in cost can be caused by political instability in oil producing nations and elsewhere, or other factors influencing global supply and demand of these materials, over which we have no or little control. We use long-term contracts (generally with fixed or formula-based costs) and advance bulk purchases to help ensure availability and continuity of supply, and to manage the risk of cost increases. From time to time we enter into hedging arrangements for certain raw materials, but do not typically enter into hedging arrangements for all raw materials, chemicals or energy costs. Should the costs of raw materials, chemicals or energy increase, and should we not be able to pass on these cost increases to our customers, then operating margins and cash flows from operating activities would be adversely impacted. Should raw material costs increase significantly, then the Company’s need for working capital could similarly increase. Any of these risks could adversely impact our results of operations, financial position and cash flows.

Item 8 Financial Statements and Supplementary Data

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Innospec Inc.:

We have audited the accompanying consolidated balance sheets of Innospec Inc. and its subsidiaries (“Innospec”) as of December 31, 2014 and 2013, and the related consolidated statements of income, comprehensive income and accumulated other comprehensive loss, cash flows and stockholders’ equity for each of the years in the three-year period ended December 31, 2014. We also have audited Innospec’s internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Innospec’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying “Management’s Report on Internal Control Over Financial Reporting” appearing in item 9A of the Form 10-K. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on Innospec’s internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable

48

assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. A material weakness related to Innospec’s lack of effective controls to ensure the proper application of ASC 830, Foreign Currency Matters, related to the treatment of foreign currency gains or losses on intercompany loan balances denominated in currencies other than the entity’s functional currency has been identified and included in management’s assessment. This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2014 consolidated financial statements.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Innospec as of December 31, 2014 and 2013, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2014, in conformity with U.S. generally accepted accounting principles. Also in our opinion, because of the effect of the aforementioned material weakness on the achievement of the objectives of the control criteria, Innospec has not maintained effective internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Innospec acquired Independence Oilfield Chemicals LLC (“Independence”) and management excluded from its assessment of the effectiveness of Innospec’s internal control over financial reporting as of December 31, 2014, Independence’s internal control over financial reporting associated with total assets of $234.7 million (of which $150.8 million represents goodwill and other intangibles included within the scope of the assessment) and total revenues of $35.0 million included in the consolidated financial statements of Innospec as of and for the year ended December 31, 2014. Our audit of internal control over financial reporting of Innospec also excluded an evaluation of the internal control over financial reporting of Independence.

Our Octane Additives business manufactures products for use in automotive gasoline and provides services in respect of environmental remediation. Our principal product lines and reportable segments are Fuel Specialties, Performance Chemicals and Octane Additives.

See Note 3 of the Notes to the Consolidated Financial Statements for financial information on the Company’s reportable segments.

Note 2.    Accounting Policies

Basis of preparation: The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America and include all subsidiaries of the Company where the Company has a controlling financial interest. All significant intercompany accounts and balances have been eliminated upon consolidation. All acquisitions are accounted for as purchases and the results of operations of the acquired businesses are included in the consolidated financial statements from the date of acquisition. We have reclassified certain prior period amounts to conform to the current period presentation.

Use of estimates: The preparation of the consolidated financial statements, in accordance with generally accepted accounting principles in the United States of America, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Cash equivalents: Investment securities with maturities of three months or less when purchased are considered to be cash equivalents.

Short-term investments: Investment securities with maturities of more than 3 months and less than 12 months when purchased are considered to be short-term investments.

Trade and other accounts receivable: The Company records trade and other accounts receivable at net realizable value and maintains allowances for customers not making required

55

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

payments. The Company determines the adequacy of allowances by periodically evaluating each customer receivable considering our customer’s financial condition, credit history and current economic conditions.

Inventories: Inventories are stated at the lower of cost (FIFO method) or market value. Cost includes materials, labor and an appropriate proportion of plant overheads. The Company accrues volume discounts where it is probable that the required volume will be attained and the amount can be reasonably estimated. The discounts are recorded as a reduction in the cost of materials based on projected purchases over the period of the agreement. Inventories are adjusted for estimated obsolescence and written down to market value based on estimates of future demand and market conditions.

Property, plant and equipment: Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is provided over the estimated useful lives of the assets using the straight-line method and is allocated between cost of goods sold and operating expenses. The cost of additions and improvements are capitalized. Maintenance and repairs are charged to expenses. When assets are sold or retired the associated cost and accumulated depreciation are removed from the consolidated financial statements and any related gain or loss is included in earnings. The estimated useful lives of the major classes of depreciable assets are as follows:

Buildings	7 to 25 years
Equipment	3 to 10 years

Goodwill and other intangible assets: Goodwill and other intangible assets deemed to have indefinite lives are not amortized but are subject to at least annual impairment tests. We perform 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 prior to performing the two-step goodwill impairment test. If this is required we assess the fair value based on projected post-tax cash flows discounted at the Company’s weighted average cost of capital. The annual measurement date for impairment testing of the goodwill relating to the Fuel Specialties and Performance Chemicals segments is December 31 each year. At this date we performed annual impairment tests and concluded that there had been no impairment of goodwill in respect of those reporting segments. The Company capitalizes software development costs, including licenses, subsequent to the establishment of technological feasibility. Other intangible assets deemed to have finite lives, including software development costs and licenses, are amortized using the straight-line method over their estimated useful lives and tested for any potential impairment when events occur or circumstances change which suggest that an impairment may have occurred.

Deferred finance costs: The costs relating to debt financing are capitalized, separately disclosed in the consolidated balance sheets and amortized using the effective interest method over the expected life of the debt financing facility.

56

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Impairment of long-lived assets: The Company reviews the carrying value of its long-lived assets, including buildings and equipment, whenever changes in circumstances suggest that the carrying values may be impaired. In order to facilitate this test 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 assets are compared with the carrying value of the assets and if they 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 cash flows discounted at the Company’s weighted average cost of capital.

Derivative instruments: From time to time, the Company uses various derivative instruments including forward currency contracts, options, interest rate swaps and commodity swaps to manage certain exposures. These instruments are entered into under the Company’s corporate risk management policy to minimize exposure and are not for speculative trading purposes. The Company recognizes all derivatives as either non-current assets or liabilities in the consolidated balance sheet and measures those instruments at fair value. Changes in the fair value of derivatives that are not designated as hedges, or do not meet the requirements for hedge accounting, are recognized in earnings. Derivatives which are designated as hedges are tested for effectiveness on a quarterly basis, and marked to market. The ineffective portion of the derivative’s change in value is recognized in earnings. The effective portion is recognized in other comprehensive income until the hedged item is recognized in earnings.

Environmental compliance and remediation: Environmental compliance costs include ongoing maintenance, monitoring and similar costs. We recognize environmental liabilities when they are probable and costs can be reasonably estimated, and asset retirement obligations when there is a legal obligation and costs can be reasonably estimated. Such accruals are adjusted as further information develops or circumstances change. Costs of future obligations are discounted to their present values using the Company’s credit-adjusted risk-free rate.

Acquisition-related contingent and deferred consideration: Deferred consideration payable in cash is discounted to its fair value. Where deferred consideration is contingent upon pre-determined financial targets, an estimate of the fair value of the likely consideration payable is made. This contingent deferred consideration is re-assessed annually and a corresponding adjustment is recognized in operating income, and the associated liability, to reflect the passage of time accretion expense and any revisions to the amount or timing of the initial measurement.

Revenue recognition: The Company supplies products to customers from its various manufacturing sites, and in some instances from containers held on customer sites, under a variety of standard shipping terms and conditions. In each case revenue is recognized when legal title, which is defined and generally accepted in the standard terms and conditions, and risk of loss transfers between the Company and the customer. Provisions for sales discounts and rebates to customers are based upon the terms of sales contracts and are recorded in the

57

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

same period as the related sales as a deduction from revenue. The Company estimates the provision for sales discounts and rebates based on the terms of each agreement at the time of shipping.

Components of net sales: All amounts billed to customers relating to shipping and handling are classified as net sales. Shipping and handling costs incurred by the Company are classified as cost of goods sold.

Components of cost of goods sold: Cost of goods sold is comprised of raw material costs including inbound freight, duty and non-recoverable taxes, inbound handling costs associated with the receipt of raw materials, packaging materials, manufacturing costs including labor costs, maintenance and utility costs, plant and engineering overheads, amortization expense for certain other intangible assets, warehousing and outbound shipping costs and handling costs. Inventory losses and provisions and the costs of customer claims are also recognized in the cost of goods line item.

Components of selling, general and administrative expenses: Selling expenses comprise the costs of the direct sales force, and the sales management and customer service departments required to support them. It also comprises commission charges, the costs of sales conferences and trade shows, the cost of advertising and promotions, amortization expense for certain other intangible assets, and the cost of bad and doubtful debts. General and administrative expenses comprise the cost of support functions including accounting, human resources, information technology and the cost of group functions including corporate management, finance, tax, treasury, investor relations and legal departments. Provision of management’s best estimate of legal and settlement costs for litigation in which the Company is involved is made and reported in the administrative expense line item.

Research and development expenses: Research, development and testing costs are expensed to the income statement as incurred.

Earnings per share: Basic earnings per share is based on the weighted average number of common shares outstanding during the period. Diluted earnings per share includes the effect of options that are dilutive and outstanding during the period.

Foreign currencies: The Company’s policy is that foreign exchange differences arising on the translation of the balance sheets of entities that have functional currencies other than the U.S. dollar are taken to a separate equity reserve, the cumulative translation adjustment. In entities 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 net income/(expense). 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 net income/(expense) in the income statement.

58

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Stock-based compensation plans: The Company accounts for employee stock options and stock equivalent units under the fair value method. Stock options are fair valued at the grant date and the fair value is recognized straight-line over the vesting period of the option. Stock equivalent units are fair valued at each balance sheet date and the fair value is spread over the remaining vesting period of the unit.

Pension plans and other post-employment benefits: The Company recognizes the funded status of defined benefit post-retirement plans on the consolidated balance sheets and changes in the funded status in comprehensive income. The measurement date of the plan’s funded status is the same as the Company’s fiscal year-end. The service costs are recognized as employees render the services necessary to earn the post-employment benefits. Prior service costs and credits and actuarial gains and losses are amortized over the average remaining life expectancy of the inactive participants using the corridor method.

Income taxes: The Company provides for income taxes by recognizing deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the relevant tax bases of the assets and liabilities. When appropriate, the Company evaluates the need for a valuation allowance to reduce deferred tax assets. The effect on deferred taxes of a change in tax rates is recognized in the period that includes the enactment date. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company recognizes accrued interest and penalties associated with uncertain tax positions as part of income taxes in our consolidated statements of income.

Note 3.     Segmental Reporting and Geographical Area Data

Innospec divides its business into three segments for management and reporting purposes: Fuel Specialties, Performance Chemicals and Octane Additives. The Fuel Specialties and Performance Chemicals segments operate in markets where we actively seek growth opportunities although their ultimate customers are different. The Octane Additives segment is generally characterized by volatile and declining demand.

In 2014, the Company had as a significant customer in the Fuel Specialties segment, Royal Dutch Shell plc and its affiliates (“Shell”), which accounted for $81.9 million (8.5%) of our net group sales. In 2013 and 2012, Shell accounted for $83.1 million (10%) and $82.9 million (11%) of our net group sales, respectively.

The Company includes within the corporate costs line item the costs of:

• managing the Group as a company with securities listed on the NASDAQ and registered with the SEC;

• the President/CEO’s office, group finance, group human resources, group legal and compliance counsel, and investor relations;

• running the corporate offices in the U.S. and Europe;

• the corporate development function since they do not relate to the current trading activities of our other reporting segments; and

Net book amount	$	229.4		$	46.7		$	0.0		$	276.1

(1) Gross cost is net of $8.7 million, $0.3 million and $289.5 million of historical accumulated amortization in respect of the Fuel Specialties, Performance Chemicals and Octane Additives reporting segments, respectively.

The Company’s reporting units, the level at which goodwill is tested for impairment, are consistent with the reportable segments: Fuel Specialties, Performance Chemicals and Octane Additives. 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 tests goodwill annually for impairment, or between years if events occur or circumstances change which suggests impairment may have occurred. At December 31, 2014, the fair value of our Fuel Specialties and Performance Chemicals segments substantially exceeds the carrying value.

64

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

To determine the fair value of each of our segments we utilize a discounted cash flow methodology based on the forecast future after-tax cash flows from operations for each since we believe this provides the best approximation of fair value. This methodology requires us to make assumptions and estimates including those in respect of future revenue growth and gross margins, which are based upon our long range plans, and the Company’s weighted average cost of capital. Our long range plans are regularly updated as part of our planning processes and are reviewed and approved by management and our Board of Directors. We assume terminal values for the Fuel Specialties and Performance Chemicals reporting units which are added to the present value of the relevant forecast future cash flows. We assume no terminal value for the Octane Additives reporting unit beyond its estimated future life. The discounted cash flow methodology does not assume a control premium. We use a discount rate equivalent to the Company’s weighted average cost of capital which is estimated by reference to the overall after-tax rate of return required by equity and debt market participants in the Company. We assign assets and liabilities, including deferred taxes and goodwill, to our reporting units if the asset or liability relates to the operations of that reporting unit and is included in determining the fair value of the reporting unit. Cash and debt obligations are excluded from the carrying value of our reporting units.

In 2014 some of the assumptions and estimates underpinning our discounted cash flows were revised as part of our planning processes although the methodology was unchanged. The most significant revisions were that the Company’s weighted average cost of capital was changed to reflect the changing proportion of debt to equity funding of the Company.

The Company elected to perform its annual tests in respect of Fuel Specialties and Performance Chemicals goodwill as at December 31 each year. At December 31, 2014 we had $229.4 million and $46.7 million of goodwill relating to our Fuel Specialties and Performance Chemicals segments, respectively. At this date we performed annual impairment tests and concluded that there had been no impairment of goodwill in respect of those reporting segments.

We believe that the assumptions used in our annual and quarterly impairment tests are reasonable, but that they are judgmental, and variations in any of the assumptions may result in materially different calculations of impairment charges, if any.

Independence Acquisition

On October 27, 2014, the Company acquired 100% of the membership interests in Independence Oilfield Chemicals LLC (“Independence”). Independence, based in Houston Texas, services the oil and gas industry, with a focus on completion, stimulation and production chemicals. We purchased Independence for a total discounted consideration of $191.8 million, with an initial payment at closing of $99.0 million funded from existing cash and debt facilities. As Independence has been in a phase of very rapid growth, the remaining payments are performance related and contingently payable over the next two years based on a

65

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

multiple of Independence’s annualized earnings before interest, taxes, depreciation and amortization plus a percentage of free cash flow. Based on the current forecasts for Independence’s performance, Innospec will make two deferred consideration payments, with the first one being $45.7 million payable approximately one year after closing, and the second one being $49.5 million payable approximately two years after closing, with a portion of such deferred payments payable, at Innospec’s election, in shares of Innospec’s common stock. We acquired the business in order to move forward our strategy of building a new market leader in the oilfield specialties sector which forms part of our Fuel Specialties segment.

Included in the consolidated income statement of the Company since the acquisition date, are the following revenue and earnings for Independence, including an accretion charge of $2.4 million:

Note 9.     Pension Plans

United Kingdom plan

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 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. The Plan’s assets are invested by several investment management companies in funds holding United Kingdom and overseas equities, United Kingdom and overseas fixed interest securities, index linked securities, property unit trusts and cash or cash equivalents. The trustees’ investment policy is to seek to achieve specified objectives through investing in a suitable mixture of real and monetary assets. The trustees recognize that the returns on real assets, while expected to be greater over the long-term than those on monetary assets, are likely to be more volatile. A mixture across asset classes should nevertheless provide the level of returns required by the Plan to meet its liabilities at an acceptable level of risk for the trustees and an acceptable level of cost to the Company.

During the second quarter of 2010 the Company implemented a pension increase exchange (“PIE”) program for current pensioners, effective April 1, 2010, which reduced the PBO by $17.1 million. This reduction in PBO resulted in a prior service credit which is being amortized using the straight-line method over the remaining life expectancy of Plan pensioners of 15 years commencing April 1, 2010.

When the plan closed to future accrual in 2010 all employees became inactive and GAAP requires that the average remaining life expectancy of the inactive participants is used, instead of the average remaining service, to spread future amortization of actuarial net losses. The average remaining life expectancy of the inactive participants has been approximately 24 years since the plan closed in 2010.

In 2014, the Company contributed approximately $11.4 million in cash to the Plan in accordance with an actuarial deficit recovery plan agreed with the trustees.

Plan asset allocation by category (%):
Equity securities	32	35	33
Debt securities	63	61	61
Cash	5	4	6
	100	100	100

The discount rate used represents the annualized yield based on a cash flow matched methodology with reference to an AA corporate bond spot curve and having regard to the duration of the Plan’s liabilities. 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 0.25% change in the discount rate assumption would change the PBO by approximately $29 million and the net pension credit for 2015 by approximately $0.3 million. A 0.25% change in the level of price inflation assumption would change the PBO by approximately $22 million and the net pension credit for 2015 would be unchanged.

The current investment strategy of the Plan is to obtain an asset allocation of 65% debt securities and 35% equity securities in order to achieve a more predictable return on assets. As at December 31, 2014, approximately 50% (December 31, 2013 – 55%) of the Plan’s assets were held in index-tracking funds with one investment management company. Approximately 40% (December 31, 2013 – 25%) of the Plan’s assets were invested in United Kingdom government gilts. No more than 5% of the Plan’s assets were invested in any one individual company’s investment funds.

The accumulated benefit obligation for the Plan was $817.1 million and $819.8 million at December 31, 2014 and 2013, respectively.

For the vast majority of assets, a market approach is adopted to assess the fair value of the assets, with the inputs being the quoted market prices for the actual securities held in the relevant fund. For Level 3 assets where there is no ready market and for which no indicative dealer prices are available, fund assets are independently evaluated, with the use of agreed upon procedures conducted by an audit firm to provide independent confirmation that proper valuation procedures are being followed. Plan assets that are invested in comingled funds are valued using a unit price or net asset value that is based on the underlying investments of the fund. Level 3 assets include investments in private equities valued using significant un-observable inputs.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

As a result of the Company’s assessment of its net deferred tax assets at December 31, 2014, the Company considers it more likely than not that no valuation allowance is required for $0.6 million (2013 – $0.3 million) of its net operating loss carry forwards and that no valuation allowance is required against its foreign tax credit carry forwards (2013 – $0.0 million).

The net operating loss carry forwards arose in the U.S. and in one of the Company’s foreign subsidiaries. The net operating loss carry forwards in the U.S. arose in the prior periods as a result of state tax losses. It is expected that sufficient taxable profits will be generated in the U.S. against which these net operating loss carry forwards can be relieved prior to their expiration in 2021. The foreign tax credit carry forwards arose in the U.S. in prior periods. The Company has determined that future foreign income inclusions will be sufficient to utilize all of the $0.8 million (2013 – $4.5 million) of the foreign tax credit carry forwards prior to their expiration in 2021 and therefore no valuation allowance is required. The net operating loss carry forwards in one of the Company’s foreign subsidiaries arose in the current period and it is expected that sufficient taxable profits will be generated against which these net operating loss carry forwards can be relieved.

Should it be determined in the future that it is no longer more likely than not that these assets will be realized, a valuation allowance would be required, and the Company’s operating results would be adversely affected during the period in which such a determination would be made.

The Company is in a position to control whether or not to repatriate foreign earnings and we intend to permanently reinvest earnings overseas to fund overseas subsidiaries. No taxes have been provided for the unremitted earnings of our overseas subsidiaries as any tax basis differences relating to investments in these overseas subsidiaries are considered to be permanent in duration. The amount of unremitted earnings at December 31, 2014 and 2013 was approximately $743 million and $605 million, respectively. If these earnings are remitted, additional taxes could result after offsetting foreign income taxes paid although the calculation of the additional taxes is not practicable to compute at this time.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

On December 14, 2011, we entered into a five-year revolving credit facility which provides for borrowings by us of up to $100.0 million. The facility carries an interest rate based on U.S. dollar LIBOR plus a margin of between 1.50% and 2.25% which is dependent on the Company’s ratio of net debt to EBITDA. EBITDA is a non-GAAP measure of liquidity defined in the credit facility. The facility can be drawn down until it expires on December 14, 2016. We repaid the previous finance facility, which was due to expire on February 6, 2012, upon entering into the new credit facility.

On August 28, 2013, we amended our existing five-year revolving credit facility (“the facility”). The amendment provides for an increase in the facility available to the Company and certain subsidiaries of the Company from $100.0 million to $150.0 million and retains the term and conditions of the original facility through to December 2016. In addition, an amendment allowed the Company to request an additional amount of $50.0 million to be committed by the lenders, of which $30.0 million was committed in the fourth quarter of 2013.

On July 31, 2014 the Company increased its borrowing capacity by $20.0 million such that its credit facility now provides for borrowings by us of up to $200.0 million until it expires on December 14, 2016 and may be drawn down in full in the U.S..

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 2.5:1 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, 2014 and expects to not breach these covenants for the next 12 months. The credit facility is secured by a number of fixed and floating charges over certain assets which include key operating sites of the Company and its subsidiaries.

On September 13, 2011, the Company settled the NewMarket Corporation civil complaint. The settlement agreement included the Company issuing a $15.0 million promissory note to NewMarket Corporation payable in three equal annual installments (carrying simple interest at 1% per annum), the final installment of which was paid on September 9, 2014.

82

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The weighted average rate of interest on borrowings was 1.7% at December 31, 2014 and 1.6% at December 31, 2013. Payments of interest on long-term debt were $2.3 million, $1.0 million and $0.5 million in 2014, 2013 and 2012, respectively.

The net cash outflows in respect of refinancing costs were $0.1 million, $0.9 million and $0.0 million in 2014, 2013 and 2012, respectively.

Note 12.    Plant Closure Provisions

The principal site giving rise to environmental remediation liabilities is the manufacturing site at Ellesmere Port in the United Kingdom, which management believes is the last ongoing manufacturer of TEL. There are also environmental remediation liabilities on a much smaller scale in respect of our other manufacturing sites in the U.S. and Europe. The liability for estimated closure costs of Innospec’s manufacturing facilities includes costs for decontamination and environmental remediation activities (remediation) when demand for TEL diminishes. Severance provisions have been made in relation to Corporate personnel and personnel in each of the three reporting segments.

Movements in the provisions are summarized as follows:

(in millions)	Severance			Remediation			Total
Total at January 1, 2012	$	1.5		$	27.1		$	28.6

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Amounts due within one year refer to provisions where expenditure is expected to arise within one year of the balance sheet date. Severance charges are recognized in the income statement in selling, general and administrative expenses. Remediation costs are recognized in cost of goods sold.

Remediation

The remediation provision represents the Company’s liability for environmental liabilities and asset retirement obligations. The charge for the period in 2014 represents the accretion expense recognized of $2.8 million and a further $2.2 million primarily in respect of changes in the expected cost and scope of future remediation activities. A discount rate of 8.92% was used in valuing the remediation provision.

We recognize environmental liabilities when they are probable and costs can be reasonably estimated, and asset retirement obligations when there is a legal obligation and 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. The Company views the costs of vacating our Ellesmere Port site as contingent upon if and when it vacates the site because there is no present intention to do so. The Company has further determined that, due to the uncertain product life of TEL particularly in the market for aviation gasoline and other products being manufactured on the site, there are uncertainties as to the probability and timing of the expected costs. Such uncertainties have been considered in estimating the provision.

Remediation expenditure utilized provisions of $2.0 million, $1.9 million and $2.1 million in 2014, 2013 and 2012, respectively.

Note 13.    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 pricing convention for valuing the majority of its assets and liabilities measured and reported at fair value. The Company utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These 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

84

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

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 2014, 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, 2014				December 31, 2013
(in millions)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Assets
Non-derivatives:
Cash and cash equivalents	$	41.6	$	41.6	$	80.2	$	80.2
Short-term investments		4.7		4.7		6.6		6.6
Derivatives (Level 1 measurement):
Other non-current assets:
Foreign currency forward exchange contracts		0.0		0.0		1.0		1.0
Liabilities
Non-derivatives:
Long-term debt (including current portion)	$	139.4	$	139.4	$	148.0	$	148.0
Derivatives (Level 1 measurement):
Other non-current liabilities:
Foreign currency forward exchange contracts		1.8		1.8		0.0		0.0
Non-financial liabilities (Level 3 measurement):
Stock equivalent units		7.2		7.2		12.1		12.1
Acquisition-related contingent consideration		95.2		95.2		4.6		4.6

The following methods and assumptions were used to estimate the fair values of financial instruments:

Cash and cash equivalents, and short-term investments: The carrying amount approximates fair value because of the short-term maturities of such instruments.

Long-term debt: Long-term debt principally comprises the revolving credit facility, which was entered into in December 2011 and term loans in our recently acquired Independence business. The carrying amount of long-term debt approximates to the fair value.

Acquisition-related contingent consideration: Deferred consideration payable in cash is discounted to its fair value. Where deferred consideration is contingent upon pre-determined financial targets, an estimate of the fair value of the likely consideration payable is made.

85

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Derivatives: The fair value of derivatives relating to interest rate swaps, foreign currency forward exchange contracts and commodity swaps 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.

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.

Note 14.    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 and raw material cost exposures, as the need arises. As at December 31, 2014 and December 31, 2013 the Company did not hold any interest rate or raw material derivatives.

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, 2014 the contracts have 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 2014 was a gain of $3.4 million.

The Company sells a range of Fuel Specialties, Performance Chemicals and Octane Additives to major oil refineries 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.

Note 15.    Commitments and Contingencies

Operating leases

The Company has commitments under operating leases primarily for office space, motor vehicles and various items of computer and office equipment. The leases are expected to be renewed and replaced in the normal course of business. Rental expense was $3.7 million in 2014, $3.1 million in 2013 and $2.9 million in 2012. Future commitments under non-cancelable operating leases are as follows:

(in millions)
2015	$	4.1
2016		3.3
2017		2.8
2018		2.2
2019		1.2
Thereafter		2.5
	$	16.1

Environmental remediation obligations

Commitments in respect of environmental remediation obligations are disclosed in Note 12 of the Notes to the Consolidated Financial Statements.

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 items could in the aggregate have a material adverse effect on 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 December 31, 2014, such guarantees which are not recognized as liabilities in the consolidated financial statements amounted to $3.0 million.

87

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

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.

At December 31, 2014, the Company had authorized common stock of 40,000,000 shares (2013 – 40,000,000). Issued shares at December 31, 2014, were 29,554,500 (2013 – 29,554,500) and treasury stock amounted to 5,263,481 shares (2013 – 5,207,947).

Note 17.    Stock-Based Compensation Plans

Stock option plans

The Company has five active stock option plans, two of which provide for the grant of stock options to employees, one provides for the grant of stock options to non-employee directors, and another provides for the grant of stock options to key executives on a matching basis provided they use a proportion of their annual bonus to purchase common stock in the Company on the open market or from the Company. The fifth plan is a savings plan which provides for the grant of stock options to all Company employees provided they commit to make regular savings over a pre-defined period which can then be used to purchase common stock upon vesting of the options. The stock options have vesting periods ranging from 24 months to 6 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 2,640,000.

88

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

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 following weighted average assumptions were used to determine the grant-date fair value of options:

	2014			2013			2012
Dividend yield		1.34	%		0.11	%		0.00	%
Expected life		5 years			5 years			5 years
Volatility		30.7	%		41.1	%		60.1	%
Risk free interest rate		0.97	%		0.46	%		0.43	%

The following table summarizes the transactions of the Company’s stock option plans for the year ended December 31, 2014:

	Number of Options			Weighted Average Exercise Price		Weighted Average Grant-Date Fair Value
Outstanding at December 31, 2013		447,390		$	7.33
Granted – at discount		376,925		$	27.69	$	14.26
– at market value		21,959		$	46.03	$	14.18
Exercised		(103,282	)	$	4.47
Forfeited		(14,352	)	$	5.84
Outstanding at December 31, 2014		728,640		$	19.55

At December 31, 2014, there were 134,921 stock options that were exercisable, 51,001 had performance conditions attached.

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.

The stock option compensation cost for 2014, 2013 and 2012 was $2.6 million, $2.5 million and $3.1 million, respectively. The total intrinsic value of options exercised in 2014, 2013 and 2012 was $0.9 million, $4.7 million and $1.5 million, respectively.

The total compensation cost related to non-vested stock options not yet recognized at December 31, 2014 was $4.7 million and this cost is expected to be recognized over the weighted-average period of 2.30 years.

The cash tax benefit realized from stock option exercises totaled $0.9 million, $5.7 million and $2.7 million in 2014, 2013 and 2012, respectively. The excess tax benefit classified in financing activities was $0.4 million, $3.8 million and $2.2 million in 2014, 2013 and 2012, respectively.

89

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

No stock options awards were modified in 2014, 2013 or 2012.

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 linked to the Innospec Inc. share price. SEUs have vesting periods ranging from 11 months to 4 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, 2014 the liability for SEUs of $7.2 million is located in accrued liabilities in the consolidated balance sheets until they are cash settled.

The fair value of SEUs is measured at the balance sheet 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 following assumptions were used to determine the fair value of SEUs at the balance sheet dates:

	2014			2013			2012
Dividend yield		1.29	%		1.08	%		0.00	%
Volatility		26.0	%		37.6	%		43.8	%
Risk free interest rate		1.10	%		0.78	%		0.36	%

The following table summarizes the transactions of the Company’s SEUs for the year ended December 31, 2014:

	Number of SEUs			Weighted Average Exercise Price		Weighted Average Grant-Date Fair Value
Outstanding at December 31, 2013		403,262		$	3.64
Granted – at discount		54,713		$	0.00	$	33.84
– at market value		7,147		$	46.03	$	14.18
Exercised		(170,317	)	$	4.70
Forfeited		(8,242	)	$	5.49
Outstanding at December 31, 2014		286,563		$	3.41

At December 31, 2014, there were 91,226 SEUs that were exercisable, 79,868 had performance conditions attached.

The charges for SEUs are spread over the life of the award subject to a revaluation to fair value each quarter. The revaluation may result in a charge or a credit to the income statement in the quarter dependent upon our share price and other performance criteria.

The SEU compensation cost for 2014, 2013 and 2012 was $2.0 million, $7.1 million and $6.8 million, respectively. The total intrinsic value of SEUs exercised in 2014, 2013 and 2012 was $3.7 million, $2.2 million and $1.3 million, respectively.

The weighted-average remaining vesting period of non-vested SEUs is 1.17 years.

Additional exceptional long-term incentive plan

In the first quarter of 2014, Innospec implemented an additional exceptional long-term incentive plan to reward selected executives with a cash bonus for delivering exceptional performance. One of the elements of the plan is payable only if the Innospec share performance matches or out-performs that of competitors, as measured by the Russell 2000 Index, over the performance period January 1, 2014 to December 31, 2016. The maximum cash bonus payable under this element of the plan is $3 million and is accounted for as share-based compensation. As such, the fair value of these liability cash-settled long-term incentives is calculated on a quarterly basis. The fair value is calculated using a Monte Carlo model and is summarized as follows:

(in millions)	2014
Balance at January 1	$	0.0
Compensation charge for the period		0.1
Balance at December 31	$	0.1

The following assumptions were used in the Monte Carlo model at December 31, 2014:

	2014
Dividend yield		1.29	%
Volatility of Innospec’s share price		26.0	%
Risk free interest rate		1.10	%

Note 19.    Recently Issued Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. ASU 2014-09 is effective for annual periods, and interim periods within those years, beginning after December 15, 2016. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

Note 20.    Related Party Transactions

Mr. Robert I. Paller has been a non-executive director of the Company since November 1, 2009. The Company has retained and continues to retain Smith, Gambrell & Russell, LLP (“SGR”), a law firm with which Mr. Paller holds a position. In 2014, 2013 and 2012 the Company incurred fees payable to SGR of $1.1 million, $1.0 million and $0.8 million, respectively. As at December 31, 2014, the amount due to SGR from the Company was $0.1 million (December 31, 2013 – $0.2 million).

Note 21.    Subsequent Events

The Company has evaluated subsequent events through the date that the consolidated financial statements were issued, and has concluded that no additional disclosures are required in relation to events subsequent to the balance sheet date.

None.

Item 9A Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Based on an evaluation carried out as of the end of the period covered by this report, under the supervision and with the participation of our management, our Chief Executive Officer and our Chief Financial Officer concluded that the Company’s “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934) were not effective as of December 31, 2014 due to the material weakness described below.

Management’s Report on Internal Control Over Financial Reporting

Our management, including the Chief Executive Officer and the Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting (within the meaning of Rule 13a-15(f) under the Securities Exchange Act of 1934). The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

Internal control over financial reporting includes those policies and procedures that:

• pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America and that our receipts and expenditures are being made only in accordance with authorization of our management and directors; and

• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the consolidated financial statements.

Due to its inherent limitations, management does not believe that internal control over financial reporting will prevent or detect all errors or fraud. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

93

On October 27, 2014, the Company acquired 100% of the membership interests in Independence Oilfield Chemicals LLC (“Independence”). Management excluded from its assessment of the effectiveness of the Company’s internal control over financial reporting Independence’s internal control over financial reporting associated with total assets of $234.7 million (of which $150.8 million represents goodwill and other intangibles included within the scope of the assessment) and total revenues of $35.0 million included in the consolidated financial statements of the Company as of and for the year ended December 31, 2014.

Based on criteria in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission the evaluation of our management, including the Chief Executive Officer and the Chief Financial Officer, concluded that the Company did not maintain effective internal control over financial reporting as of December 31, 2014 due to the material weakness described below.

Treatment of Intercompany Loans Denominated in Currencies Other Than the Entity’s Functional Currency:

The Company lacked effective controls to ensure the proper application of ASC 830, Foreign Currency Matters, related to the treatment of foreign currency gains or losses on intercompany loan balances denominated in currencies other than the entity’s functional currency. According to ASC 830, intercompany loans, denominated in currencies other than the entity’s functional currency are re-measured on a periodic basis with resulting gains or losses recorded to the consolidated statement of income. If settlement is not planned or anticipated in the foreseeable future, then foreign currency exchange gains and losses are to be recorded within accumulated other comprehensive income within the equity section of the balance sheet, as the transactions and balances are considered to be of a long-term investment nature. The Company determined it was incorrectly calculating foreign exchange on intercompany loan balances and incorrectly including gains and losses in other income/(expense) in the consolidated statement of income rather than accumulated other comprehensive income in the consolidated financial statements. The Company did not maintain effective internal control over the calculation of intercompany foreign currency exchange gains or losses and lacked an effective control to assess and document at inception whether or not intercompany loan balances are long-term in nature. The ineffectiveness of the control environment did not result in an adjustment to the current year financial statements or a restatement of prior year financial statements.

Our independent registered public accounting firm KPMG Audit Plc, has audited our consolidated financial statements and the effectiveness of our internal control over financial reporting as of December 31, 2014. Their report is included in Item 8 of this Annual Report on Form 10-K.

The Company is currently engaged in carrying out its remediation plan which includes the following:

• Performing a review and confirmation of the correct evaluation and documentation of certain intercompany loans including improving the processes and controls to ensure proper application of ASC 830;

94

• Implementing additional procedures to ensure the calculation of foreign exchange gains and losses on intercompany loans to be included in other comprehensive income are correct.

Although the Company has made progress in this area, additional steps need to be taken, as indicated above, and sufficient time needs to elapse before management can conclude that newly implemented controls are operating effectively and that the material weakness has been adequately remediated.

Changes in Internal Controls over Financial Reporting

The Company is continuously seeking to improve the efficiency and effectiveness of its operations and of its internal controls. This is intended to result in refinements to processes throughout the Company. As previously disclosed, we are continuing with the process of developing a new, company-wide, information system platform which began in 2011. The platform provider is well established in the market. The implementation is a phased, risk-managed, site deployment following a multistage user acceptance program with the existing platform providing a fallback position. We implemented the new platform at the majority of our U.S. sites in the third quarter of 2013. Our next phase of implementation includes the majority of reporting units outside of the U.S. and is planned for the fourth quarter of 2015. In connection with this implementation, the Company has updated its internal controls over financial reporting, as necessary, to accommodate modifications to its business processes and accounting procedures. As a consequence, none of the changes which were identified in connection with the evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934, have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors

Innospec Inc.:

We consent to the incorporation by reference in the registration statements (No. 333-131687, 333-124139, 333-174050, and 333-174439) on Form S-8 of Innospec Inc. of our report dated February 17, 2015, with respect to the consolidated balance sheets of Innospec Inc. as of December 31, 2014 and 2013, and the related consolidated statements of income, comprehensive income and accumulated other comprehensive loss, cash flows and stockholders’ equity for each of the years in the three-year period ended December 31, 2014, and the effectiveness of internal control over financial reporting as of December 31, 2014, which report appears in the December 31, 2014 annual report on Form 10-K of Innospec Inc..

Our report dated February 17, 2015, includes our opinion that expresses that Innospec Inc. did not maintain effective internal control over financial reporting as of December 31, 2014, because of the effect of a material weakness on the achievement of the objectives of the control criteria and contains an explanatory paragraph that states that Innospec Inc. lacked effective controls to ensure the proper application of ASC 830, Foreign Currency Matters, related to the treatment of foreign currency gains or losses on intercompany loan balances denominated in currencies other than the entity’s functional currency. Our report also contains an explanatory paragraph that states that our audit of internal control over financial reporting of Innospec Inc. excluded an evaluation of the internal control over financial reporting of Independence Oilfield Chemicals LLC, which was acquired on October 27, 2014.

Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2014

Basis of preparation

Basis of preparation: The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America and include all subsidiaries of the Company where the Company has a controlling financial interest. All significant intercompany accounts and balances have been eliminated upon consolidation. All acquisitions are accounted for as purchases and the results of operations of the acquired businesses are included in the consolidated financial statements from the date of acquisition. We have reclassified certain prior period amounts to conform to the current period presentation.

Use of estimates

Use of estimates: The preparation of the consolidated financial statements, in accordance with generally accepted accounting principles in the United States of America, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Cash equivalents

Cash equivalents: Investment securities with maturities of three months or less when purchased are considered to be cash equivalents.

Short-term investments

Short-term investments: Investment securities with maturities of more than 3 months and less than 12 months when purchased are considered to be short-term investments.

Trade and other accounts receivable

Trade and other accounts receivable: The Company records trade and other accounts receivable at net realizable value and maintains allowances for customers not making required payments. The Company determines the adequacy of allowances by periodically evaluating each customer receivable considering our customer’s financial condition, credit history and current economic conditions.

Inventories

Inventories: Inventories are stated at the lower of cost (FIFO method) or market value. Cost includes materials, labor and an appropriate proportion of plant overheads. The Company accrues volume discounts where it is probable that the required volume will be attained and the amount can be reasonably estimated. The discounts are recorded as a reduction in the cost of materials based on projected purchases over the period of the agreement. Inventories are adjusted for estimated obsolescence and written down to market value based on estimates of future demand and market conditions.

Property, plant and equipment

Property, plant and equipment: Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is provided over the estimated useful lives of the assets using the straight-line method and is allocated between cost of goods sold and operating expenses. The cost of additions and improvements are capitalized. Maintenance and repairs are charged to expenses. When assets are sold or retired the associated cost and accumulated depreciation are removed from the consolidated financial statements and any related gain or loss is included in earnings. The estimated useful lives of the major classes of depreciable assets are as follows:

Buildings	7 to 25 years
Equipment	3 to 10 years

Goodwill and other intangible assets

Goodwill and other intangible assets: Goodwill and other intangible assets deemed to have indefinite lives are not amortized but are subject to at least annual impairment tests. We perform 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 prior to performing the two-step goodwill impairment test. If this is required we assess the fair value based on projected post-tax cash flows discounted at the Company’s weighted average cost of capital. The annual measurement date for impairment testing of the goodwill relating to the Fuel Specialties and Performance Chemicals segments is December 31 each year. At this date we performed annual impairment tests and concluded that there had been no impairment of goodwill in respect of those reporting segments. The Company capitalizes software development costs, including licenses, subsequent to the establishment of technological feasibility. Other intangible assets deemed to have finite lives, including software development costs and licenses, are amortized using the straight-line method over their estimated useful lives and tested for any potential impairment when events occur or circumstances change which suggest that an impairment may have occurred.

Deferred finance costs

Deferred finance costs: The costs relating to debt financing are capitalized, separately disclosed in the consolidated balance sheets and amortized using the effective interest method over the expected life of the debt financing facility.

Impairment of long-lived assets

Impairment of long-lived assets: The Company reviews the carrying value of its long-lived assets, including buildings and equipment, whenever changes in circumstances suggest that the carrying values may be impaired. In order to facilitate this test 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 assets are compared with the carrying value of the assets and if they 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 cash flows discounted at the Company’s weighted average cost of capital.

Derivative instruments

Derivative instruments: From time to time, the Company uses various derivative instruments including forward currency contracts, options, interest rate swaps and commodity swaps to manage certain exposures. These instruments are entered into under the Company’s corporate risk management policy to minimize exposure and are not for speculative trading purposes. The Company recognizes all derivatives as either non-current assets or liabilities in the consolidated balance sheet and measures those instruments at fair value. Changes in the fair value of derivatives that are not designated as hedges, or do not meet the requirements for hedge accounting, are recognized in earnings. Derivatives which are designated as hedges are tested for effectiveness on a quarterly basis, and marked to market. The ineffective portion of the derivative’s change in value is recognized in earnings. The effective portion is recognized in other comprehensive income until the hedged item is recognized in earnings.

Environmental compliance and remediation

Environmental compliance and remediation: Environmental compliance costs include ongoing maintenance, monitoring and similar costs. We recognize environmental liabilities when they are probable and costs can be reasonably estimated, and asset retirement obligations when there is a legal obligation and costs can be reasonably estimated. Such accruals are adjusted as further information develops or circumstances change. Costs of future obligations are discounted to their present values using the Company’s credit-adjusted risk-free rate.

Acquisition-related contingent and deferred consideration

Acquisition-related contingent and deferred consideration: Deferred consideration payable in cash is discounted to its fair value. Where deferred consideration is contingent upon pre-determined financial targets, an estimate of the fair value of the likely consideration payable is made. This contingent deferred consideration is re-assessed annually and a corresponding adjustment is recognized in operating income, and the associated liability, to reflect the passage of time accretion expense and any revisions to the amount or timing of the initial measurement.

Revenue recognition

Revenue recognition: The Company supplies products to customers from its various manufacturing sites, and in some instances from containers held on customer sites, under a variety of standard shipping terms and conditions. In each case revenue is recognized when legal title, which is defined and generally accepted in the standard terms and conditions, and risk of loss transfers between the Company and the customer. Provisions for sales discounts and rebates to customers are based upon the terms of sales contracts and are recorded in the same period as the related sales as a deduction from revenue. The Company estimates the provision for sales discounts and rebates based on the terms of each agreement at the time of shipping.

Components of net sales

Components of net sales: All amounts billed to customers relating to shipping and handling are classified as net sales. Shipping and handling costs incurred by the Company are classified as cost of goods sold.

Components of cost of goods sold

Components of cost of goods sold: Cost of goods sold is comprised of raw material costs including inbound freight, duty and non-recoverable taxes, inbound handling costs associated with the receipt of raw materials, packaging materials, manufacturing costs including labor costs, maintenance and utility costs, plant and engineering overheads, amortization expense for certain other intangible assets, warehousing and outbound shipping costs and handling costs. Inventory losses and provisions and the costs of customer claims are also recognized in the cost of goods line item.

Components of selling, general and administrative expenses

Components of selling, general and administrative expenses: Selling expenses comprise the costs of the direct sales force, and the sales management and customer service departments required to support them. It also comprises commission charges, the costs of sales conferences and trade shows, the cost of advertising and promotions, amortization expense for certain other intangible assets, and the cost of bad and doubtful debts. General and administrative expenses comprise the cost of support functions including accounting, human resources, information technology and the cost of group functions including corporate management, finance, tax, treasury, investor relations and legal departments. Provision of management’s best estimate of legal and settlement costs for litigation in which the Company is involved is made and reported in the administrative expense line item.

Research and development expenses

Research and development expenses: Research, development and testing costs are expensed to the income statement as incurred.

Earnings per share

Earnings per share: Basic earnings per share is based on the weighted average number of common shares outstanding during the period. Diluted earnings per share includes the effect of options that are dilutive and outstanding during the period.

Foreign currencies

Foreign currencies: The Company’s policy is that foreign exchange differences arising on the translation of the balance sheets of entities that have functional currencies other than the U.S. dollar are taken to a separate equity reserve, the cumulative translation adjustment. In entities 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 net income/(expense). 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 net income/(expense) in the income statement.

Stock-based compensation plans

Stock-based compensation plans: The Company accounts for employee stock options and stock equivalent units under the fair value method. Stock options are fair valued at the grant date and the fair value is recognized straight-line over the vesting period of the option. Stock equivalent units are fair valued at each balance sheet date and the fair value is spread over the remaining vesting period of the unit.

Pension plans and other post-employment benefits

Pension plans and other post-employment benefits: The Company recognizes the funded status of defined benefit post-retirement plans on the consolidated balance sheets and changes in the funded status in comprehensive income. The measurement date of the plan’s funded status is the same as the Company’s fiscal year-end. The service costs are recognized as employees render the services necessary to earn the post-employment benefits. Prior service costs and credits and actuarial gains and losses are amortized over the average remaining life expectancy of the inactive participants using the corridor method.

Income taxes

Income taxes: The Company provides for income taxes by recognizing deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the relevant tax bases of the assets and liabilities. When appropriate, the Company evaluates the need for a valuation allowance to reduce deferred tax assets. The effect on deferred taxes of a change in tax rates is recognized in the period that includes the enactment date. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company recognizes accrued interest and penalties associated with uncertain tax positions as part of income taxes in our consolidated statements of income.

Customer Contracts [Member]

Revenue recognition

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. ASU 2014-09 is effective for annual periods, and interim periods within those years, beginning after December 15, 2016. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

Derivative Instruments and Risk Management

Note 14.    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 and raw material cost exposures, as the need arises. As at December 31, 2014 and December 31, 2013 the Company did not hold any interest rate or raw material derivatives.

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, 2014 the contracts have 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 2014 was a gain of $3.4 million.

The Company sells a range of Fuel Specialties, Performance Chemicals and Octane Additives to major oil refineries 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.

Stock-Based Compensation Plans

Note 17.    Stock-Based Compensation Plans

Stock option plans

The Company has five active stock option plans, two of which provide for the grant of stock options to employees, one provides for the grant of stock options to non-employee directors, and another provides for the grant of stock options to key executives on a matching basis provided they use a proportion of their annual bonus to purchase common stock in the Company on the open market or from the Company. The fifth plan is a savings plan which provides for the grant of stock options to all Company employees provided they commit to make regular savings over a pre-defined period which can then be used to purchase common stock upon vesting of the options. The stock options have vesting periods ranging from 24 months to 6 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 2,640,000.

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 following weighted average assumptions were used to determine the grant-date fair value of options:

	2014			2013			2012
Dividend yield		1.34	%		0.11	%		0.00	%
Expected life		5 years			5 years			5 years
Volatility		30.7	%		41.1	%		60.1	%
Risk free interest rate		0.97	%		0.46	%		0.43	%

The following table summarizes the transactions of the Company’s stock option plans for the year ended December 31, 2014:

	Number of Options			Weighted Average Exercise Price		Weighted Average Grant-Date Fair Value
Outstanding at December 31, 2013		447,390		$	7.33
Granted – at discount		376,925		$	27.69	$	14.26
– at market value		21,959		$	46.03	$	14.18
Exercised		(103,282	)	$	4.47
Forfeited		(14,352	)	$	5.84
Outstanding at December 31, 2014		728,640		$	19.55

At December 31, 2014, there were 134,921 stock options that were exercisable, 51,001 had performance conditions attached.

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.

The stock option compensation cost for 2014, 2013 and 2012 was $2.6 million, $2.5 million and $3.1 million, respectively. The total intrinsic value of options exercised in 2014, 2013 and 2012 was $0.9 million, $4.7 million and $1.5 million, respectively.

The total compensation cost related to non-vested stock options not yet recognized at December 31, 2014 was $4.7 million and this cost is expected to be recognized over the weighted-average period of 2.30 years.

The cash tax benefit realized from stock option exercises totaled $0.9 million, $5.7 million and $2.7 million in 2014, 2013 and 2012, respectively. The excess tax benefit classified in financing activities was $0.4 million, $3.8 million and $2.2 million in 2014, 2013 and 2012, respectively.

No stock options awards were modified in 2014, 2013 or 2012.

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 linked to the Innospec Inc. share price. SEUs have vesting periods ranging from 11 months to 4 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, 2014 the liability for SEUs of $7.2 million is located in accrued liabilities in the consolidated balance sheets until they are cash settled.

The fair value of SEUs is measured at the balance sheet 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 following assumptions were used to determine the fair value of SEUs at the balance sheet dates:

	2014			2013			2012
Dividend yield		1.29	%		1.08	%		0.00	%
Volatility		26.0	%		37.6	%		43.8	%
Risk free interest rate		1.10	%		0.78	%		0.36	%

The following table summarizes the transactions of the Company’s SEUs for the year ended December 31, 2014:

	Number of SEUs			Weighted Average Exercise Price		Weighted Average Grant-Date Fair Value
Outstanding at December 31, 2013		403,262		$	3.64
Granted – at discount		54,713		$	0.00	$	33.84
– at market value		7,147		$	46.03	$	14.18
Exercised		(170,317	)	$	4.70
Forfeited		(8,242	)	$	5.49
Outstanding at December 31, 2014		286,563		$	3.41

At December 31, 2014, there were 91,226 SEUs that were exercisable, 79,868 had performance conditions attached.

The charges for SEUs are spread over the life of the award subject to a revaluation to fair value each quarter. The revaluation may result in a charge or a credit to the income statement in the quarter dependent upon our share price and other performance criteria.

The SEU compensation cost for 2014, 2013 and 2012 was $2.0 million, $7.1 million and $6.8 million, respectively. The total intrinsic value of SEUs exercised in 2014, 2013 and 2012 was $3.7 million, $2.2 million and $1.3 million, respectively.

The weighted-average remaining vesting period of non-vested SEUs is 1.17 years.

Additional exceptional long-term incentive plan

In the first quarter of 2014, Innospec implemented an additional exceptional long-term incentive plan to reward selected executives with a cash bonus for delivering exceptional performance. One of the elements of the plan is payable only if the Innospec share performance matches or out-performs that of competitors, as measured by the Russell 2000 Index, over the performance period January 1, 2014 to December 31, 2016. The maximum cash bonus payable under this element of the plan is $3 million and is accounted for as share-based compensation. As such, the fair value of these liability cash-settled long-term incentives is calculated on a quarterly basis. The fair value is calculated using a Monte Carlo model and is summarized as follows:

(in millions)	2014
Balance at January 1	$	0.0
Compensation charge for the period		0.1
Balance at December 31	$	0.1

The following assumptions were used in the Monte Carlo model at December 31, 2014:

	2014
Dividend yield		1.29	%
Volatility of Innospec’s share price		26.0	%
Risk free interest rate		1.10	%

Note 19.    Recently Issued Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. ASU 2014-09 is effective for annual periods, and interim periods within those years, beginning after December 15, 2016. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

On December 14, 2011, we entered into a five-year revolving credit facility which provides for borrowings by us of up to $100.0 million. The facility carries an interest rate based on U.S. dollar LIBOR plus a margin of between 1.50% and 2.25% which is dependent on the Company’s ratio of net debt to EBITDA. EBITDA is a non-GAAP measure of liquidity defined in the credit facility. The facility can be drawn down until it expires on December 14, 2016. We repaid the previous finance facility, which was due to expire on February 6, 2012, upon entering into the new credit facility.

On August 28, 2013, we amended our existing five-year revolving credit facility (“the facility”). The amendment provides for an increase in the facility available to the Company and certain subsidiaries of the Company from $100.0 million to $150.0 million and retains the term and conditions of the original facility through to December 2016. In addition, an amendment allowed the Company to request an additional amount of $50.0 million to be committed by the lenders, of which $30.0 million was committed in the fourth quarter of 2013.

On July 31, 2014 the Company increased its borrowing capacity by $20.0 million such that its credit facility now provides for borrowings by us of up to $200.0 million until it expires on December 14, 2016 and may be drawn down in full in the U.S..

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 2.5:1 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, 2014 and expects to not breach these covenants for the next 12 months. The credit facility is secured by a number of fixed and floating charges over certain assets which include key operating sites of the Company and its subsidiaries.

On September 13, 2011, the Company settled the NewMarket Corporation civil complaint. The settlement agreement included the Company issuing a $15.0 million promissory note to NewMarket Corporation payable in three equal annual installments (carrying simple interest at 1% per annum), the final installment of which was paid on September 9, 2014.

The weighted average rate of interest on borrowings was 1.7% at December 31, 2014 and 1.6% at December 31, 2013. Payments of interest on long-term debt were $2.3 million, $1.0 million and $0.5 million in 2014, 2013 and 2012, respectively.

The net cash outflows in respect of refinancing costs were $0.1 million, $0.9 million and $0.0 million in 2014, 2013 and 2012, respectively.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 13.    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 pricing convention for valuing the majority of its assets and liabilities measured and reported at fair value. The Company utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These 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 2014, 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, 2014				December 31, 2013
(in millions)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Assets
Non-derivatives:
Cash and cash equivalents	$	41.6	$	41.6	$	80.2	$	80.2

Derivatives (Level 1 measurement):
Other non-current assets:
Foreign currency forward exchange contracts		0.0		0.0		1.0		1.0
Liabilities
Non-derivatives:
Long-term debt (including current portion)	$	139.4	$	139.4	$	148.0	$	148.0
Derivatives (Level 1 measurement):
Other non-current liabilities:
Foreign currency forward exchange contracts		1.8		1.8		0.0		0.0
Non-financial liabilities (Level 3 measurement):
Stock equivalent units		7.2		7.2		12.1		12.1
Acquisition-related contingent consideration		95.2		95.2		4.6		4.6

The following methods and assumptions were used to estimate the fair values of financial instruments:

Cash and cash equivalents, and short-term investments: The carrying amount approximates fair value because of the short-term maturities of such instruments.

Long-term debt: Long-term debt principally comprises the revolving credit facility, which was entered into in December 2011 and term loans in our recently acquired Independence business. The carrying amount of long-term debt approximates to the fair value.

Acquisition-related contingent consideration: Deferred consideration payable in cash is discounted to its fair value. Where deferred consideration is contingent upon pre-determined financial targets, an estimate of the fair value of the likely consideration payable is made.

Derivatives: The fair value of derivatives relating to interest rate swaps, foreign currency forward exchange contracts and commodity swaps 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.

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.

(1) Gross cost is net of $8.7 million, $0.3 million and $289.5 million of historical accumulated amortization in respect of the Fuel Specialties, Performance Chemicals and Octane Additives reporting segments, respectively.

The Company’s reporting units, the level at which goodwill is tested for impairment, are consistent with the reportable segments: Fuel Specialties, Performance Chemicals and Octane Additives. 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 tests goodwill annually for impairment, or between years if events occur or circumstances change which suggests impairment may have occurred. At December 31, 2014, the fair value of our Fuel Specialties and Performance Chemicals segments substantially exceeds the carrying value.

To determine the fair value of each of our segments we utilize a discounted cash flow methodology based on the forecast future after-tax cash flows from operations for each since we believe this provides the best approximation of fair value. This methodology requires us to make assumptions and estimates including those in respect of future revenue growth and gross margins, which are based upon our long range plans, and the Company’s weighted average cost of capital. Our long range plans are regularly updated as part of our planning processes and are reviewed and approved by management and our Board of Directors. We assume terminal values for the Fuel Specialties and Performance Chemicals reporting units which are added to the present value of the relevant forecast future cash flows. We assume no terminal value for the Octane Additives reporting unit beyond its estimated future life. The discounted cash flow methodology does not assume a control premium. We use a discount rate equivalent to the Company’s weighted average cost of capital which is estimated by reference to the overall after-tax rate of return required by equity and debt market participants in the Company. We assign assets and liabilities, including deferred taxes and goodwill, to our reporting units if the asset or liability relates to the operations of that reporting unit and is included in determining the fair value of the reporting unit. Cash and debt obligations are excluded from the carrying value of our reporting units.

In 2014 some of the assumptions and estimates underpinning our discounted cash flows were revised as part of our planning processes although the methodology was unchanged. The most significant revisions were that the Company’s weighted average cost of capital was changed to reflect the changing proportion of debt to equity funding of the Company.

The Company elected to perform its annual tests in respect of Fuel Specialties and Performance Chemicals goodwill as at December 31 each year. At December 31, 2014 we had $229.4 million and $46.7 million of goodwill relating to our Fuel Specialties and Performance Chemicals segments, respectively. At this date we performed annual impairment tests and concluded that there had been no impairment of goodwill in respect of those reporting segments.

We believe that the assumptions used in our annual and quarterly impairment tests are reasonable, but that they are judgmental, and variations in any of the assumptions may result in materially different calculations of impairment charges, if any.

Independence Acquisition

On October 27, 2014, the Company acquired 100% of the membership interests in Independence Oilfield Chemicals LLC (“Independence”). Independence, based in Houston Texas, services the oil and gas industry, with a focus on completion, stimulation and production chemicals. We purchased Independence for a total discounted consideration of $191.8 million, with an initial payment at closing of $99.0 million funded from existing cash and debt facilities. As Independence has been in a phase of very rapid growth, the remaining payments are performance related and contingently payable over the next two years based on a multiple of Independence’s annualized earnings before interest, taxes, depreciation and amortization plus a percentage of free cash flow. Based on the current forecasts for Independence’s performance, Innospec will make two deferred consideration payments, with the first one being $45.7 million payable approximately one year after closing, and the second one being $49.5 million payable approximately two years after closing, with a portion of such deferred payments payable, at Innospec’s election, in shares of Innospec’s common stock. We acquired the business in order to move forward our strategy of building a new market leader in the oilfield specialties sector which forms part of our Fuel Specialties segment.

Included in the consolidated income statement of the Company since the acquisition date, are the following revenue and earnings for Independence, including an accretion charge of $2.4 million:

(in millions)	Independence
Net sales	$	35.0
Net income	$	0.2

The following table summarizes the calculations of the total purchase price and the estimated allocation of the purchase price to the assets acquired and liabilities assumed for Independence. The purchase price allocation is not yet complete as we are in the process of finalising the valuation of the assets acquired. Final determination of the fair values may result in adjustments to the amounts presented below:

(in millions)	Independence
Goodwill	$	88.1
Other intangible assets		63.8
Fixed assets		18.6

Purchase price, net of cash acquired	$	191.8

Independence, and the associated goodwill, are included within our Fuel Specialties segment for management and reporting purposes (see Note 7 of the Notes to the Consolidated Financial Statements for further information on the other intangible assets). There is currently no goodwill amortizable for tax purposes.

The amount attributed to the Octane Additives reporting segment was being amortized straight-line to December 31, 2012 and the amount attributed to the Fuel Specialties reporting segment is being amortized straight-line to December 31, 2017. Effective October 1, 2011, the Company extended its estimate for the future life of the Octane Additives segment from December 31, 2012 to December 31, 2013 and therefore prospectively adjusted the amortization period for the amount attributed to the Octane Additives segment. An amortization expense of $1.0 million was recognized in 2014 (2013 – $1.7 million) in cost of goods sold.

Amortization expense

The aggregate of other intangible asset amortization expense was $17.8 million, $11.1 million and $4.1 million in 2014, 2013 and 2012, respectively, of which $7.4 million, $3.8 million and $2.6 million, respectively, was recognized in cost of goods sold, and the remainder was recognized in selling, general and administrative expenses.

Plant Closure Provisions

Note 12.    Plant Closure Provisions

The principal site giving rise to environmental remediation liabilities is the manufacturing site at Ellesmere Port in the United Kingdom, which management believes is the last ongoing manufacturer of TEL. There are also environmental remediation liabilities on a much smaller scale in respect of our other manufacturing sites in the U.S. and Europe. The liability for estimated closure costs of Innospec’s manufacturing facilities includes costs for decontamination and environmental remediation activities (remediation) when demand for TEL diminishes. Severance provisions have been made in relation to Corporate personnel and personnel in each of the three reporting segments.

Movements in the provisions are summarized as follows:

(in millions)	Severance			Remediation			Total
Total at January 1, 2012	$	1.5		$	27.1		$	28.6

Amounts due within one year refer to provisions where expenditure is expected to arise within one year of the balance sheet date. Severance charges are recognized in the income statement in selling, general and administrative expenses. Remediation costs are recognized in cost of goods sold.

Remediation

The remediation provision represents the Company’s liability for environmental liabilities and asset retirement obligations. The charge for the period in 2014 represents the accretion expense recognized of $2.8 million and a further $2.2 million primarily in respect of changes in the expected cost and scope of future remediation activities. A discount rate of 8.92% was used in valuing the remediation provision.

We recognize environmental liabilities when they are probable and costs can be reasonably estimated, and asset retirement obligations when there is a legal obligation and 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. The Company views the costs of vacating our Ellesmere Port site as contingent upon if and when it vacates the site because there is no present intention to do so. The Company has further determined that, due to the uncertain product life of TEL particularly in the market for aviation gasoline and other products being manufactured on the site, there are uncertainties as to the probability and timing of the expected costs. Such uncertainties have been considered in estimating the provision.

Remediation expenditure utilized provisions of $2.0 million, $1.9 million and $2.1 million in 2014, 2013 and 2012, respectively.

Accounting Policies [Abstract]

Accounting Policies

Note 2.    Accounting Policies

Basis of preparation: The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America and include all subsidiaries of the Company where the Company has a controlling financial interest. All significant intercompany accounts and balances have been eliminated upon consolidation. All acquisitions are accounted for as purchases and the results of operations of the acquired businesses are included in the consolidated financial statements from the date of acquisition. We have reclassified certain prior period amounts to conform to the current period presentation.

Use of estimates: The preparation of the consolidated financial statements, in accordance with generally accepted accounting principles in the United States of America, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Cash equivalents: Investment securities with maturities of three months or less when purchased are considered to be cash equivalents.

Short-term investments: Investment securities with maturities of more than 3 months and less than 12 months when purchased are considered to be short-term investments.

Trade and other accounts receivable: The Company records trade and other accounts receivable at net realizable value and maintains allowances for customers not making required payments. The Company determines the adequacy of allowances by periodically evaluating each customer receivable considering our customer’s financial condition, credit history and current economic conditions.

Inventories: Inventories are stated at the lower of cost (FIFO method) or market value. Cost includes materials, labor and an appropriate proportion of plant overheads. The Company accrues volume discounts where it is probable that the required volume will be attained and the amount can be reasonably estimated. The discounts are recorded as a reduction in the cost of materials based on projected purchases over the period of the agreement. Inventories are adjusted for estimated obsolescence and written down to market value based on estimates of future demand and market conditions.

Property, plant and equipment: Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is provided over the estimated useful lives of the assets using the straight-line method and is allocated between cost of goods sold and operating expenses. The cost of additions and improvements are capitalized. Maintenance and repairs are charged to expenses. When assets are sold or retired the associated cost and accumulated depreciation are removed from the consolidated financial statements and any related gain or loss is included in earnings. The estimated useful lives of the major classes of depreciable assets are as follows:

Buildings	7 to 25 years
Equipment	3 to 10 years

Goodwill and other intangible assets: Goodwill and other intangible assets deemed to have indefinite lives are not amortized but are subject to at least annual impairment tests. We perform 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 prior to performing the two-step goodwill impairment test. If this is required we assess the fair value based on projected post-tax cash flows discounted at the Company’s weighted average cost of capital. The annual measurement date for impairment testing of the goodwill relating to the Fuel Specialties and Performance Chemicals segments is December 31 each year. At this date we performed annual impairment tests and concluded that there had been no impairment of goodwill in respect of those reporting segments. The Company capitalizes software development costs, including licenses, subsequent to the establishment of technological feasibility. Other intangible assets deemed to have finite lives, including software development costs and licenses, are amortized using the straight-line method over their estimated useful lives and tested for any potential impairment when events occur or circumstances change which suggest that an impairment may have occurred.

Deferred finance costs: The costs relating to debt financing are capitalized, separately disclosed in the consolidated balance sheets and amortized using the effective interest method over the expected life of the debt financing facility.

Impairment of long-lived assets: The Company reviews the carrying value of its long-lived assets, including buildings and equipment, whenever changes in circumstances suggest that the carrying values may be impaired. In order to facilitate this test 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 assets are compared with the carrying value of the assets and if they 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 cash flows discounted at the Company’s weighted average cost of capital.

Derivative instruments: From time to time, the Company uses various derivative instruments including forward currency contracts, options, interest rate swaps and commodity swaps to manage certain exposures. These instruments are entered into under the Company’s corporate risk management policy to minimize exposure and are not for speculative trading purposes. The Company recognizes all derivatives as either non-current assets or liabilities in the consolidated balance sheet and measures those instruments at fair value. Changes in the fair value of derivatives that are not designated as hedges, or do not meet the requirements for hedge accounting, are recognized in earnings. Derivatives which are designated as hedges are tested for effectiveness on a quarterly basis, and marked to market. The ineffective portion of the derivative’s change in value is recognized in earnings. The effective portion is recognized in other comprehensive income until the hedged item is recognized in earnings.

Environmental compliance and remediation: Environmental compliance costs include ongoing maintenance, monitoring and similar costs. We recognize environmental liabilities when they are probable and costs can be reasonably estimated, and asset retirement obligations when there is a legal obligation and costs can be reasonably estimated. Such accruals are adjusted as further information develops or circumstances change. Costs of future obligations are discounted to their present values using the Company’s credit-adjusted risk-free rate.

Acquisition-related contingent and deferred consideration: Deferred consideration payable in cash is discounted to its fair value. Where deferred consideration is contingent upon pre-determined financial targets, an estimate of the fair value of the likely consideration payable is made. This contingent deferred consideration is re-assessed annually and a corresponding adjustment is recognized in operating income, and the associated liability, to reflect the passage of time accretion expense and any revisions to the amount or timing of the initial measurement.

Revenue recognition: The Company supplies products to customers from its various manufacturing sites, and in some instances from containers held on customer sites, under a variety of standard shipping terms and conditions. In each case revenue is recognized when legal title, which is defined and generally accepted in the standard terms and conditions, and risk of loss transfers between the Company and the customer. Provisions for sales discounts and rebates to customers are based upon the terms of sales contracts and are recorded in the same period as the related sales as a deduction from revenue. The Company estimates the provision for sales discounts and rebates based on the terms of each agreement at the time of shipping.

Components of net sales: All amounts billed to customers relating to shipping and handling are classified as net sales. Shipping and handling costs incurred by the Company are classified as cost of goods sold.

Components of cost of goods sold: Cost of goods sold is comprised of raw material costs including inbound freight, duty and non-recoverable taxes, inbound handling costs associated with the receipt of raw materials, packaging materials, manufacturing costs including labor costs, maintenance and utility costs, plant and engineering overheads, amortization expense for certain other intangible assets, warehousing and outbound shipping costs and handling costs. Inventory losses and provisions and the costs of customer claims are also recognized in the cost of goods line item.

Components of selling, general and administrative expenses: Selling expenses comprise the costs of the direct sales force, and the sales management and customer service departments required to support them. It also comprises commission charges, the costs of sales conferences and trade shows, the cost of advertising and promotions, amortization expense for certain other intangible assets, and the cost of bad and doubtful debts. General and administrative expenses comprise the cost of support functions including accounting, human resources, information technology and the cost of group functions including corporate management, finance, tax, treasury, investor relations and legal departments. Provision of management’s best estimate of legal and settlement costs for litigation in which the Company is involved is made and reported in the administrative expense line item.

Research and development expenses: Research, development and testing costs are expensed to the income statement as incurred.

Earnings per share: Basic earnings per share is based on the weighted average number of common shares outstanding during the period. Diluted earnings per share includes the effect of options that are dilutive and outstanding during the period.

Foreign currencies: The Company’s policy is that foreign exchange differences arising on the translation of the balance sheets of entities that have functional currencies other than the U.S. dollar are taken to a separate equity reserve, the cumulative translation adjustment. In entities 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 net income/(expense). 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 net income/(expense) in the income statement.

Stock-based compensation plans: The Company accounts for employee stock options and stock equivalent units under the fair value method. Stock options are fair valued at the grant date and the fair value is recognized straight-line over the vesting period of the option. Stock equivalent units are fair valued at each balance sheet date and the fair value is spread over the remaining vesting period of the unit.

Pension plans and other post-employment benefits: The Company recognizes the funded status of defined benefit post-retirement plans on the consolidated balance sheets and changes in the funded status in comprehensive income. The measurement date of the plan’s funded status is the same as the Company’s fiscal year-end. The service costs are recognized as employees render the services necessary to earn the post-employment benefits. Prior service costs and credits and actuarial gains and losses are amortized over the average remaining life expectancy of the inactive participants using the corridor method.

Income taxes: The Company provides for income taxes by recognizing deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the relevant tax bases of the assets and liabilities. When appropriate, the Company evaluates the need for a valuation allowance to reduce deferred tax assets. The effect on deferred taxes of a change in tax rates is recognized in the period that includes the enactment date. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company recognizes accrued interest and penalties associated with uncertain tax positions as part of income taxes in our consolidated statements of income.

Segmental Reporting and Geographical Area Data

Note 3.     Segmental Reporting and Geographical Area Data

Innospec divides its business into three segments for management and reporting purposes: Fuel Specialties, Performance Chemicals and Octane Additives. The Fuel Specialties and Performance Chemicals segments operate in markets where we actively seek growth opportunities although their ultimate customers are different. The Octane Additives segment is generally characterized by volatile and declining demand.

In 2014, the Company had as a significant customer in the Fuel Specialties segment, Royal Dutch Shell plc and its affiliates (“Shell”), which accounted for $81.9 million (8.5%) of our net group sales. In 2013 and 2012, Shell accounted for $83.1 million (10%) and $82.9 million (11%) of our net group sales, respectively.

The Company evaluates the performance of its segments based on operating income. The following table analyzes sales and other financial information by the Company’s reportable segments:

Restructuring charges separately disclosed in prior periods have been reclassified to corporate costs. We have reclassified the prior period amounts to conform to the current period presentation.

The pension charge relates to the United Kingdom defined benefit pension plan which is closed to future service accrual. The charges related to our other much smaller pension arrangements in the U.S. and overseas are included in the segment and income statement captions consistent with the related employees’ costs.

The Company includes within the corporate costs line item the costs of:

• managing the Group as a company with securities listed on the NASDAQ and registered with the SEC;

• the President/CEO’s office, group finance, group human resources, group legal and compliance counsel, and investor relations;

• running the corporate offices in the U.S. and Europe;

• the corporate development function since they do not relate to the current trading activities of our other reporting segments; and

• the corporate share of the information technology, accounting and human resources departments.

Sales by geographical area are reported by source, being where the transactions originated. Intercompany sales are priced using an appropriate pricing methodology and are eliminated in the consolidated financial statements.

Identifiable assets are those directly associated with the operations of the geographical area.

Goodwill has not been allocated by geographical location on the grounds that it would be impracticable to do so.

All of the $6.2 million of unrecognized tax benefits, and interest and penalties, would impact our effective tax rate if recognized.

We recognize accrued interest and penalties associated with uncertain tax positions as part of income taxes in our consolidated statements of income.

The Company or one of its subsidiaries files income tax returns with the U.S. federal government, and various state and foreign jurisdictions. As previously disclosed, as at December 31, 2013, the Company and its U.S. subsidiaries were subject to tax audits in the U.S.. On March 6, 2014, the federal income tax examination by the IRS for 2009 was effectively settled. The additional tax cost was nominal and resulted in a reduction of $3.6 million in unrecognized tax benefits and a reduction of $0.4 million in associated interest and penalties in the first quarter of 2014. During the third quarter of 2014, the Company recorded a reduction of $2.9 million in unrecognized tax benefits and $0.2 million in associated interest and penalties due to the expiration of applicable statutes of limitations and there was a $0.3 million addition to unrecognized tax benefits recorded during the fourth quarter of 2014.

The Company and its U.S. subsidiaries remain open to examination by the IRS for years 2011 onwards. The Company’s subsidiaries in foreign tax jurisdictions are open to examination including France (2013 onwards), Germany (2010 onwards), Switzerland (2013 onwards) and the United Kingdom (2013 onwards).

The sources of income before income taxes were as follows:

(in millions)	2014		2013		2012
Domestic	$	15.2	$	10.0	$	5.6
Foreign		95.7		82.8		87.7
	$	110.9	$	92.8	$	93.3

The components of income tax charges are summarized as follows:

(in millions)	2014		2013		2012
Current:
Federal	$	4.5	$	0.8	$	2.3
State and local		2.1		0.8		0.6
Foreign		14.9		6.8		11.8
		21.5		8.4		14.7
Deferred:
Federal		3.3		1.7		11.4

Foreign		1.7		4.8		(0.6	)
		5.3		6.6		11.7
	$	26.8	$	15.0	$	26.4

Cash payments for income taxes were $11.6 million, $21.1 million and $13.1 million during 2014, 2013 and 2012, respectively.

The effective tax rate varies from the U.S. federal statutory rate because of the factors indicated below:

	2014			2013			2012
Statutory rate		35.0	%		35.0	%		35.0	%
Foreign income inclusions		5.5			4.2			10.5
Foreign tax rate differential		(14.6	)		(14.6	)		(16.4	)
Tax charge/(credit) from previous years		4.7			(2.9	)		(0.6	)
Net charge/(credit) from unrecognized tax benefits		(6.2	)		0.2			0.3
Foreign currency translation		1.0			(2.7	)		(1.0	)
Other items and adjustments, net		(1.2	)		(3.0	)		0.5
		24.2	%		16.2	%		28.3	%

Significant factors affecting the variation to statutory rate are set out above and include foreign income inclusions net of foreign tax credits. The mix of taxable profits generated in the different geographical localities in which the Group operates had a significant positive impact on the effective tax rate in 2014.

Details of deferred tax assets and liabilities are analyzed as follows:

(in millions)	2014			2013
Deferred tax assets:
Foreign tax credits	$	0.8		$	4.5
Accrued expenses		0.3			3.4
Stock options		5.0			5.2

Current portion of deferred tax liabilities		0.0			(0.2	)
Deferred tax liabilities, net of current portion		(23.0	)		(9.5	)
	$	(13.9	)	$	7.6

Details of the deferred tax asset valuation allowance are as follows:

(in millions)	2014		2013		2012
At January 1	$	0.0	$	0.0	$	(7.5	)
Change in foreign tax credits		0.0		0.0		7.5
At December 31	$	0.0	$	0.0	$	0.0

As a result of the Company’s assessment of its net deferred tax assets at December 31, 2014, the Company considers it more likely than not that no valuation allowance is required for $0.6 million (2013 – $0.3 million) of its net operating loss carry forwards and that no valuation allowance is required against its foreign tax credit carry forwards (2013 – $0.0 million).

The net operating loss carry forwards arose in the U.S. and in one of the Company’s foreign subsidiaries. The net operating loss carry forwards in the U.S. arose in the prior periods as a result of state tax losses. It is expected that sufficient taxable profits will be generated in the U.S. against which these net operating loss carry forwards can be relieved prior to their expiration in 2021. The foreign tax credit carry forwards arose in the U.S. in prior periods. The Company has determined that future foreign income inclusions will be sufficient to utilize all of the $0.8 million (2013 – $4.5 million) of the foreign tax credit carry forwards prior to their expiration in 2021 and therefore no valuation allowance is required. The net operating loss carry forwards in one of the Company’s foreign subsidiaries arose in the current period and it is expected that sufficient taxable profits will be generated against which these net operating loss carry forwards can be relieved.

Should it be determined in the future that it is no longer more likely than not that these assets will be realized, a valuation allowance would be required, and the Company’s operating results would be adversely affected during the period in which such a determination would be made.

The Company is in a position to control whether or not to repatriate foreign earnings and we intend to permanently reinvest earnings overseas to fund overseas subsidiaries. No taxes have been provided for the unremitted earnings of our overseas subsidiaries as any tax basis differences relating to investments in these overseas subsidiaries are considered to be permanent in duration. The amount of unremitted earnings at December 31, 2014 and 2013 was approximately $743 million and $605 million, respectively. If these earnings are remitted, additional taxes could result after offsetting foreign income taxes paid although the calculation of the additional taxes is not practicable to compute at this time.

Note 15.    Commitments and Contingencies

Operating leases

The Company has commitments under operating leases primarily for office space, motor vehicles and various items of computer and office equipment. The leases are expected to be renewed and replaced in the normal course of business. Rental expense was $3.7 million in 2014, $3.1 million in 2013 and $2.9 million in 2012. Future commitments under non-cancelable operating leases are as follows:

Environmental remediation obligations

Commitments in respect of environmental remediation obligations are disclosed in Note 12 of the Notes to the Consolidated Financial Statements.

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 items could in the aggregate have a material adverse effect on 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 December 31, 2014, such guarantees which are not recognized as liabilities in the consolidated financial statements amounted to $3.0 million.

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.

Pension Plans

Note 9.     Pension Plans

United Kingdom plan

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 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. The Plan’s assets are invested by several investment management companies in funds holding United Kingdom and overseas equities, United Kingdom and overseas fixed interest securities, index linked securities, property unit trusts and cash or cash equivalents. The trustees’ investment policy is to seek to achieve specified objectives through investing in a suitable mixture of real and monetary assets. The trustees recognize that the returns on real assets, while expected to be greater over the long-term than those on monetary assets, are likely to be more volatile. A mixture across asset classes should nevertheless provide the level of returns required by the Plan to meet its liabilities at an acceptable level of risk for the trustees and an acceptable level of cost to the Company.

During the second quarter of 2010 the Company implemented a pension increase exchange (“PIE”) program for current pensioners, effective April 1, 2010, which reduced the PBO by $17.1 million. This reduction in PBO resulted in a prior service credit which is being amortized using the straight-line method over the remaining life expectancy of Plan pensioners of 15 years commencing April 1, 2010.

When the plan closed to future accrual in 2010 all employees became inactive and GAAP requires that the average remaining life expectancy of the inactive participants is used, instead of the average remaining service, to spread future amortization of actuarial net losses. The average remaining life expectancy of the inactive participants has been approximately 24 years since the plan closed in 2010.

In 2014, the Company contributed approximately $11.4 million in cash to the Plan in accordance with an actuarial deficit recovery plan agreed with the trustees.

(in millions)	2014			2013			2012
Plan net pension charge/(credit):
Service cost	$	1.7		$	1.6		$	1.6

Discount rate		3.55			4.40			4.15
Inflation rate		2.15			2.55			2.20
Rate of return on plan assets – overall on bid-value		4.05			4.85			4.90
Rate of return on plan assets – equity securities		6.50			7.50			7.25
Rate of return on plan assets – debt securities		2.75			3.40			3.65

Plan asset allocation by category (%):
Equity securities	32	35	33
Debt securities	63	61	61
Cash	5	4	6
	100	100	100

The discount rate used represents the annualized yield based on a cash flow matched methodology with reference to an AA corporate bond spot curve and having regard to the duration of the Plan’s liabilities. 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 0.25% change in the discount rate assumption would change the PBO by approximately $29 million and the net pension credit for 2015 by approximately $0.3 million. A 0.25% change in the level of price inflation assumption would change the PBO by approximately $22 million and the net pension credit for 2015 would be unchanged.

The current investment strategy of the Plan is to obtain an asset allocation of 65% debt securities and 35% equity securities in order to achieve a more predictable return on assets. As at December 31, 2014, approximately 50% (December 31, 2013 – 55%) of the Plan’s assets were held in index-tracking funds with one investment management company. Approximately 40% (December 31, 2013 – 25%) of the Plan’s assets were invested in United Kingdom government gilts. No more than 5% of the Plan’s assets were invested in any one individual company’s investment funds.

Movements in PBO and fair value of Plan assets are as follows:

(in millions)	2014			2013
Change in PBO:
Opening balance	$	819.8		$	805.3
Interest cost		34.7			31.3

Actual return on assets		161.7			35.5
Exchange effect		(53.5	)		14.8
Closing balance	$	862.3		$	790.3

The accumulated benefit obligation for the Plan was $817.1 million and $819.8 million at December 31, 2014 and 2013, respectively.

For the vast majority of assets, a market approach is adopted to assess the fair value of the assets, with the inputs being the quoted market prices for the actual securities held in the relevant fund. For Level 3 assets where there is no ready market and for which no indicative dealer prices are available, fund assets are independently evaluated, with the use of agreed upon procedures conducted by an audit firm to provide independent confirmation that proper valuation procedures are being followed. Plan assets that are invested in comingled funds are valued using a unit price or net asset value that is based on the underlying investments of the fund. Level 3 assets include investments in private equities valued using significant un-observable inputs.

The fair values of pension assets by level of input were as follows:

(in millions)	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
