NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Financial Statement Presentation

In the opinion of management, the accompanying consolidated financial statements of NewMarket Corporation and its subsidiaries contain all necessary adjustments for the fair statement of, in all material respects, our consolidated financial position as of September 30, 2011 and December 31, 2010, and the change in our shareholders’ equity for the nine months ended September 30, 2011 and the year ended December 31, 2010, as well as our consolidated results of operations for the third quarter and nine months ended September 30, 2011 and September 30, 2010 and our cash flows for the nine months ended September 30, 2011 and September 30, 2010. All adjustments are of a normal, recurring nature, unless otherwise disclosed. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the NewMarket Corporation Annual Report on Form 10-K for the year ended December 31, 2010 (2010 Annual Report), as filed with the Securities and Exchange Commission (SEC). The results of operations for the nine month period ended September 30, 2011 are not necessarily indicative of the results to be expected for the full year ending December 31, 2011. The December 31, 2010 consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

Unless the context otherwise requires, all references to “we,” “us,” “our,” the “Company” and “NewMarket” are to NewMarket Corporation and its consolidated subsidiaries.

Certain reclassifications have been made to the accompanying consolidated financial statements and the related notes to conform to the current presentation.

At both September 30, 2011 and December 31, 2010, we had a book overdraft for some of our disbursement cash accounts. A book overdraft represents transactions that have not cleared the bank accounts at the end of the reporting period. There are no agreements with the same banks to offset the presented balance. We transfer cash on an as-needed basis to fund these items as they clear the bank in subsequent periods.

Cash dividends for the nine months ended September 30, 2011 and September 30, 2010 were declared and paid as shown in the table below.

Year	Date Declared	Date Paid	Per Share Amount
2011	February 17, 2011	April 1, 2011		44.0 cents
	April 20, 2011	July 1, 2011		60.0 cents
	July 21, 2011	October 1, 2011		60.0 cents
2010	February 18, 2010	April 1, 2010		37.5 cents
	April 22, 2010	July 1, 2010		37.5 cents
	July 21, 2010	October 1, 2010		37.5 cents

(a) For both third quarter 2011 and nine months 2011, the petroleum additives segment includes a net gain of $38.7 million related to a legal settlement. On September 13, 2011, we signed a settlement agreement with Innospec Inc. and its subsidiaries, Alcor Chemie Vertriebs GmbH and Innospec Ltd. (collectively, Innospec) which provided for mutual releases of the parties and a dismissal of the actions with prejudice. Under the settlement agreement, Innospec will pay NewMarket an aggregate amount of approximately $45 million in a combination of cash, a promissory note, and stock, of which $25 million was paid in cash on September 20, 2011 and approximately $5 million was paid in the form of 195,313 shares of unregistered Innospec Inc. common stock. Fifteen million dollars is payable in three equal annual installments of $5 million under the promissory note, which bears simple interest at 1% per year. The first installment is due on September 10, 2012. The gain is net of expenses related to the settlement of the lawsuit.

(b) The loss on the interest rate swap agreement represents the change, since the beginning of the reporting period, in the fair value of an interest rate swap which we entered into on June 25, 2009. We are not using hedge accounting to record the interest rate swap, and accordingly, any change in the fair value is immediately recognized in earnings.

5. Earnings Per Share

Basic and diluted earnings per share are calculated as shown in the table below. Options are not included in the computation of diluted earnings per share when the option exercise price exceeds the average market price of the underlying common share, as the impact on earnings per share would be anti-dilutive. We had no anti-dilutive options that were excluded from the calculation of earnings per share for any period presented.

We were in compliance with all covenants under our debt agreements at September 30, 2011 and December 31, 2010.

8. Contractual Commitments and Contingencies

There have been no significant changes in our contractual commitments and contingencies from those reported in our 2010 Annual Report on Form 10-K in Note 18, except as discussed below. The information below provides information on certain contractual commitments and contingencies.

Litigation

We are involved in legal proceedings that are incidental to our business and include administrative or judicial actions seeking remediation under environmental laws, such as Superfund. Some of these legal proceedings relate to environmental matters and involve governmental authorities. For further information, see “Environmental” below.

While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

As previously disclosed, NewMarket Corporation and Afton Chemical Corporation (collectively, NewMarket) brought two civil actions against Innospec Inc. and its subsidiaries Alcor Chemie Vertriebs GmbH and Innospec Ltd. (collectively, Innospec) in July 2010.

15

NewMarket and Innospec have agreed to settle these actions pursuant to the terms of a settlement agreement between them signed on September 13, 2011 which provides for mutual releases of the parties and dismissal of the actions with prejudice. Under the settlement agreement, Innospec will pay NewMarket an aggregate amount of approximately $45 million, payable in a combination of cash, a promissory note, and stock, of which $25 million was paid in cash on September 20, 2011 and approximately $5 million was paid in the form of 195,313 shares of unregistered Innospec Inc. common stock. Fifteen million dollars is payable in three equal annual installments of $5 million under the promissory note, which bears interest at 1% per year. The first installment is due on September 10, 2012.

Environmental

During 2000, the U.S. Environmental Protection Agency (EPA) named us as a potentially responsible party (PRP) under Superfund law for the clean-up of soil and groundwater contamination at the Sauget Area 2 Site in Sauget, Illinois. Without admitting any fact, responsibility, fault, or liability in connection with this site, we are participating with other PRPs in site investigations and feasibility studies. The Sauget Area 2 Site PRPs received notice of approval from the EPA of their October 2009 Human Health Risk Assessment. Additionally, the PRPs have submitted their Feasibility Study (FS) to the EPA Remedy Review Board. We have accrued our estimated proportional share of the expenses for the FS, as well as our best estimate of our proportional share of the remediation liability proposed in our ongoing discussions and submissions with the agencies involved. The amount currently accrued for this site is not material.

At a former TEL plant site located in Louisiana, we have completed significant environmental remediation, although we will be monitoring and treating the site for an extended period. The accrual for this site was $6.3 million at September 30, 2011 and $6.8 million at December 31, 2010. We based these amounts on the best estimate of future costs discounted at approximately 3% in both 2011 and 2010. An inflation factor is included in the estimate. The undiscounted liability was $8.1 million at September 30, 2011 and $8.7 million at December 31, 2010. The expected payments over the next five years amount to approximately $200 thousand in 2011, $700 thousand in 2012, and $600 thousand for each of the years 2013 through 2015. Expected payments thereafter amount to approximately $5.4 million.

At a plant site in Houston, Texas, we have accruals of $7.5 million at September 30, 2011 and $7.6 million at December 31, 2010 for environmental remediation, dismantling, and decontamination. Included in these amounts are $6.8 million at September 30, 2011 and $7.3 million at December 31, 2010 for remediation. Of the total remediation, $6.5 million at September 30, 2011 and $6.9 million at December 31, 2010 relates to remediation of groundwater and soil. The accruals for this site are discounted at approximately 3% at both September 30, 2011 and December 31, 2010 and include an inflation factor. The undiscounted accrual for this site was $10.5 million at September 30, 2011 and $10.8 million at December 31, 2010. The expected payments over the next five years are approximately $1.0 million in 2012, $500 thousand in 2013, $1.7 million in 2014, and $200 thousand in 2015. Expected payments thereafter amount to approximately $7.1 million.

At a Superfund site in Louisiana, we have an accrual of $3.3 million at both September 30, 2011 and December 31, 2010 for environmental remediation. The accrual for this site was discounted at approximately 3% at both September 30, 2011 and December 31, 2010 and included an inflation factor. The undiscounted accrual for this site was $4.2 million at both September 30, 2011 and December 31, 2010. The expected payments over the next five years amount to approximately $100 thousand in 2011, $300 thousand in 2012, $200 thousand in 2013, and $300 thousand each for years 2014 and 2015. Expected payments thereafter amount to approximately $3.0 million.

16

The remaining environmental liabilities are not discounted.

We accrue for environmental remediation and monitoring activities for which costs can be reasonably estimated and are probable. These estimates are based on an assessment of the site, available clean-up methods, and prior experience in handling remediation. While we believe we are currently fully accrued for known environmental issues, it is possible that unexpected future costs could have a significant impact on our financial position, results of operations, and cash flows.

Our total accruals for environmental remediation were approximately $22.2 million at September 30, 2011 and $22.5 million at December 31, 2010. In addition to the accruals for environmental remediation, we also have accruals for dismantling and decommissioning costs of $600 thousand at September 30, 2011 and $500 thousand at December 31, 2010.

Letters of Credit and Guarantees

We have outstanding guarantees with several financial institutions in the amount of $56.5 million at September 30, 2011. The guarantees are secured by letters of credit, as well as cash collateral. A portion of the guarantees is unsecured. The outstanding letters of credit amounted to $6.4 million at September 30, 2011, all of which were issued under the letter of credit sub-facility of our revolving credit facility. The letters of credit primarily relate to insurance and performance guarantees. The remaining amounts represent additional performance, lease, custom and excise tax guarantees, as well as a cash deposit of $34.2 million related to the Goldman Sachs Bank USA (Goldman Sachs) interest rate swap. The cash deposit is recorded in “Other assets and deferred charges” on the Consolidated Balance Sheets. Expiration dates of the letters of credit and certain guarantees range from 2011 to 2014. Some of the guarantees have no expiration date. We renew letters of credit as necessary.

We cannot estimate the maximum amount of potential liability under the guarantees. However, we accrue for potential liabilities when a future payment is probable and the range of loss can be reasonably estimated.

9. Derivatives and Hedging Activities

Accounting Policy for Derivative Instruments and Hedging Activities

We record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. We may enter into derivative contracts that are intended to economically hedge certain of our risks, even though hedge accounting does not apply or we elect not to apply hedge accounting. We do not enter into derivative instruments for speculative purposes.

17

Risk Management Objective of Using Derivatives

We are exposed to certain risks arising from both our business operations and economic conditions. We primarily manage our exposures to a wide variety of business and operational risks through management of our core business activities.

We manage certain economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of our debt funding, as well as through the use of derivative financial instruments. Specifically, we have entered into interest rate swaps to manage our exposure to interest rate movements.

Our foreign operations expose us to fluctuations of foreign exchange rates. These fluctuations may impact the value of our cash receipts and payments as compared to our reporting currency, the U.S. Dollar. To manage this exposure, we sometimes enter into foreign currency forward contracts to minimize currency exposure due to cash flows from foreign operations.

Cash Flow Hedge of Interest Rate Risk

In January 2010, we entered into an interest rate swap to manage our exposure to interest rate movements on the Foundry Park I mortgage loan and to reduce variability in interest expense. Further information on the mortgage loan is in Note 12 in our 2010 Annual Report. We also had an interest rate swap to manage our exposure to interest rate movements on the Foundry Park I construction loan and add stability to capitalized interest expense. The Foundry Park I construction loan interest rate swap matured on January 1, 2010. Both interest rate swaps are designated and qualify as a cash flow hedge. As such, the effective portion of changes in the fair value of the swaps is recorded in accumulated other comprehensive loss and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Any ineffective portion of changes in the fair value of the swap is recognized immediately in earnings. We assess the effectiveness of the mortgage loan interest rate swap quarterly by comparing the changes in the fair value of the derivative hedging instrument with the change in present value of the expected future cash flows of the hedged transaction.

The mortgage loan interest rate swap involves the receipt of variable-rate amounts based on LIBOR in exchange for fixed-rate payments over the life of the agreement without exchange of the underlying notional amount. The fixed-rate payments are at a rate of 2.642% for the mortgage loan interest rate swap. The notional amount of the mortgage loan interest rate swap was $68.4 million at origination and approximately $64.2 million at September 30, 2011. The notional amount of the mortgage loan interest rate swap amortizes to approximately $53.7 million over the term of the swap. The amortizing notional amount is necessary to maintain the swap notional at an amount that matches the declining mortgage loan principal balance over the loan term. The mortgage loan interest swap matures on January 29, 2015.

The unrealized loss, net of tax, related to the fair value of the mortgage loan interest rate swap is recorded in accumulated other comprehensive loss in shareholders’ equity on the Consolidated Balance Sheets, and amounted to approximately $2.3 million at September 30, 2011 and $1.5 million at December 31, 2010. Also recorded as a component of accumulated other comprehensive loss in shareholders’ equity on the Consolidated Balance Sheets is the accumulated losses related to the construction loan interest rate swap of approximately $2.6 million, net of tax, at both September 30, 2011 and December 31, 2010. The amount remaining in accumulated other comprehensive loss related to the construction loan interest rate swap is being recognized in the Consolidated Statements of Income over the depreciable life of the office building. Approximately $900 thousand, net of tax, currently recognized in accumulated other comprehensive loss related to both the construction loan interest rate swap and the mortgage loan interest rate swap is expected to be reclassified into earnings over the next twelve months.

18

Non-designated Hedges

On June 25, 2009, we entered into an interest rate swap with Goldman Sachs in the notional amount of $97 million and with a maturity date of January 19, 2022 (Goldman Sachs interest rate swap). NewMarket entered into the Goldman Sachs interest rate swap in connection with the termination of a loan application and related rate lock agreement between Foundry Park I and Principal Commercial Funding II, LLC (Principal). When the rate lock agreement was originally executed in 2007, Principal simultaneously entered into an interest rate swap with a third party to hedge Principal’s exposure to fluctuation in the ten-year United States Treasury Bond rate. Upon the termination on June 25, 2009 of the rate lock agreement, Goldman Sachs both assumed Principal’s position with the third party and entered into an offsetting interest rate swap with NewMarket. Under the terms of this interest rate swap, NewMarket will make fixed rate payments at 5.3075% and Goldman Sachs will make variable rate payments based on three-month LIBOR. We have collateralized this exposure through cash deposits posted with Goldman Sachs amounting to $34.2 million at September 30, 2011. This transaction effectively preserves the impact of the original rate lock agreement for the possible application to a future loan of a similar structure.

We do not use hedge accounting for the Goldman Sachs interest rate swap, and therefore, immediately recognize any change in the fair value of this derivative financial instrument in earnings.

Credit-risk-related Contingent Features

We have agreements with both of our current derivative counterparties that contain a provision where we could be declared in default on our derivative obligations if repayment of indebtedness is accelerated by our lender(s) due to our default on the indebtedness.

As of September 30, 2011, the fair value of derivatives in a net liability position related to these agreements, which includes accrued interest but excludes any adjustment for nonperformance risk, was $34.1 million. We have minimum collateral posting thresholds with one of our derivative counterparties and have posted cash collateral of $34.2 million as of September 30, 2011. If required, we could have settled our obligations under the agreements at their termination value of $34.1 million at September 30, 2011.

We determine the fair value of the derivative instruments shown in the table above by using widely-accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each instrument. The analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs.

The fair value of the interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments are based on an expectation of future interest rates derived from observable market interest rate curves. In determining the fair value measurements, we incorporate credit valuation adjustments to appropriately reflect both our nonperformance risk and the counterparties’ nonperformance risk.

24

Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustment associated with the derivatives utilizes Level 3 inputs. These Level 3 inputs include estimates of current credit spreads to evaluate the likelihood of default by both us and the counterparties to the derivatives. We have assessed the significance of the impact of the credit valuation adjustment and determined the credit valuation adjustment is not significant to the overall valuation of the derivatives. Accordingly, we have determined that our derivative valuations should be classified in Level 2 of the fair value hierarchy.

The marketable securities in the table above represent the 195,313 shares of unregistered Innospec Inc. common stock that we own. See Note 8 for further information. The fair value of the common stock is determined using the closing market price of Innospec common stock at September 30, 2011, discounted for transfer restrictions on the shares. While the Innospec common stock is traded on a national exchange and the market price is a Level 1 input in the fair value hierarchy, the discount factor utilizes Level 3 inputs. We have assessed the significance of the impact of the discount factor adjustment on the overall valuation of the marketable securities and have determined that it is not significant to the overall valuation of the marketable securities. Accordingly, we have determined that our marketable securities valuation should be classified in Level 2 of the fair value hierarchy as the valuation relies on quoted prices for similar assets in an active market.

We record the value of our long-term debt at historical cost. The estimated fair value of our long-term debt is shown in the table below and is based primarily on estimated current rates available to us for debt of the same remaining duration and adjusted for nonperformance risk and credit risk. The fair value is categorized as Level 2.

12. Consolidating Financial Information

The 7.125% senior notes due 2016 (senior notes) are guaranteed by certain of our subsidiaries (Guarantor Subsidiaries) on a joint and several unsecured senior basis. The senior notes include a provision which allows for a Guarantor Subsidiary to be released of any obligation under the subsidiary guarantee under certain conditions. Those conditions include the sale or other disposition of all or substantially all of the Guarantor Subsidiary’s assets. The Guarantor Subsidiaries include all of our existing and future 100% owned domestic restricted subsidiaries. The Guarantor Subsidiaries and the subsidiaries that do not guarantee the senior notes (the Non-Guarantor Subsidiaries) are 100% owned by NewMarket Corporation (the Parent Company). The Guarantor Subsidiaries consist of the following:

Ethyl Corporation	Afton Chemical Corporation
Ethyl Asia Pacific LLC	Afton Chemical Asia Pacific LLC
Ethyl Canada Holdings, Inc.	Afton Chemical Canada Holdings, Inc.

25

Ethyl Export Corporation	Afton Chemical Japan Holdings, Inc.
Ethyl Interamerica Corporation	Afton Chemical Additives Corporation
Ethyl Ventures, Inc.	Afton Chemical Intangibles LLC
Interamerica Terminals Corporation	The Edwin Cooper Corporation
NewMarket Development Corporation	NewMarket Investment Company
NewMarket Services Corporation	Old Town LLC
Foundry Park I, LLC	Foundry Park II, LLC
Gamble’s Hill, LLC	Gamble’s Hill Lab, LLC
Gamble’s Hill Landing, LLC	Gamble’s Hill Third Street, LLC
Gamble’s Hill Tredegar, LLC

We conduct all of our business and derive essentially all of our income from our subsidiaries. Therefore, our ability to make payments on the senior notes or other obligations is dependent on the earnings and the distribution of funds from our subsidiaries. There are no restrictions on the ability of any of our domestic subsidiaries to transfer funds to the Parent Company.

The following sets forth the Consolidating Statements of Income for the third quarter and nine months ended September 30, 2011 and September 30, 2010; Consolidating Balance Sheets as of September 30, 2011 and December 31, 2010; and Condensed Consolidating Statements of Cash Flows for the nine months ended September 30, 2011 and September 30, 2010 for the Parent Company, the Guarantor Subsidiaries, and Non-Guarantor Subsidiaries. The financial information is based on our understanding of the SEC’s interpretation and application of Rule 3-10 of the SEC Regulation S-X.

The financial information may not necessarily be indicative of their results of operations or financial positions had the Guarantor Subsidiaries or Non-Guarantor Subsidiaries operated as independent entities. The Parent Company accounts for investments in these subsidiaries using the equity method.

13. Recently Issued Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2011-08, “Intangibles – Goodwill and Other (Topic 350)” (ASU 2011-08). ASU 2011-08 simplifies goodwill impairment testing by allowing an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. An entity is no longer required to determine the fair value of a reporting unit unless it is more likely than not that the fair value is less than carrying value. ASU 2011-08 is effective for interim and annual periods beginning after December 15, 2011. Early adoption is permitted. We are evaluating the provisions of ASU 2011-08 and will apply its provisions by the beginning of the first quarter 2012.

In June 2011, the FASB issued Accounting Standards Update 2011-05, “Comprehensive Income (Topic 220) – Presentation of Comprehensive Income” (ASU 2011-05). ASU 2011-05 requires that all nonowner changes in stockholders’ equity be presented either in a single continuous consolidated statement of comprehensive income or in two separate, but consecutive, consolidated statements of income and consolidated statements of comprehensive income. The option to present comprehensive income as part of the consolidated statement of stockholders’ equity has been eliminated. ASU 2011-05 is effective for interim and annual periods beginning after December 15, 2011 and will be applied retrospectively. We will modify our financial statements beginning with our March 31, 2012 Quarterly Report on Form 10-Q to adopt the requirements.

In May 2011, the FASB issued Accounting Standards Update 2011-04, “Fair Value Measurement (Topic 820) – Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (ASU 2011-04). ASU 2011-04 results in common fair value measurement, as well as disclosure requirements, under U.S. GAAP and IFRS. The amendments clarify guidance on measuring fair value, but do not require any additional fair value measurements. ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011. Early application is not permitted. We do not expect ASU 2011-04 will have a significant impact on our financial statements.

14. Subsequent Events

On October 27, 2011, our Board of Directors declared a quarterly dividend in the amount of 75 cents per share on our common stock. The dividend is payable January 1, 2012 to shareholders of record at the close of business on December 15, 2011.

ITEM 2. Management’s Discussion and Analysis of

Financial Condition and Results of Operations

Forward-Looking Statements

The following discussion contains forward-looking statements about future events and expectations within the meaning of the Private Securities Litigation Reform Act of 1995. We have based these forward-looking statements on our current expectations and projections about future results. When we use words in this document, such as “anticipates,” “intends,” “plans,” “believes,” “estimates,” “expects,” “should,” “could,” “may,” “will,” and similar expressions, we do so to identify forward-looking statements. Examples of forward-looking statements include, but are not limited to, statements we make regarding future prospects of growth in the petroleum additives market, other trends in the petroleum additives market, our ability to maintain or increase our market share, and our future capital expenditure levels.

We believe our forward-looking statements are based on reasonable expectations and assumptions, within the bounds of what we know about our business and operations. However, we offer no assurance that actual results will not differ materially from our expectations due to uncertainties and factors that are difficult to predict and beyond our control.

Factors that could cause actual results to differ materially from expectations include, but are not limited to: availability of raw materials and transportation systems; supply disruptions at single-sourced facilities; ability to respond effectively to technological changes in our industry; failure to protect our intellectual property rights; hazards common to chemical businesses; occurrence or threat of extraordinary events, including natural disasters and terrorist attacks; competition from other manufacturers; sudden or sharp raw materials price increases; gain or loss of significant customers; risks related to operating outside of the United States; the impact of fluctuations in foreign exchange rates; political, economic, and regulatory factors concerning our products; future governmental regulation; resolution of environmental liabilities or legal proceedings; inability to complete recent or future acquisitions or successfully integrate recent or future acquisitions into our business and other factors detailed from time to time in the reports that NewMarket files with the Securities and Exchange Commission, including the risk factors in Item 1A, “Risk Factors” of our 2010 Annual Report, which is available to shareholders upon request.

You should keep in mind that any forward-looking statement made by us in this discussion or elsewhere speaks only as of the date on which we make it. New risks and uncertainties arise from time to time, and it is impossible for us to predict these events or how they may affect us. We have no duty to, and do not intend to, update or revise the forward-looking statements in this discussion after the date hereof, except as may be required by law. In light of these risks and uncertainties, you should keep in mind that the events described in any forward-looking statement, made in this discussion or elsewhere, might not occur.

Overview

While we have seen some slowdown in the rate of increase in demand for our products during the third quarter 2011, operations during the first nine months 2011 continued to generate strong results with increased net sales, operating profit, and product shipments in our petroleum additives segment over nine months 2010. During nine months 2011, we repurchased 659,373 shares of our common stock for $94.8 million. Also, our working capital position improved during nine months 2011, and we ended September 2011 with $55 million drawn on the $300 million revolving credit facility.

36

On September 13, 2011, we signed a settlement agreement with Innospec Inc. and its subsidiaries, Alcor Chemie Vertriebs GmbH and Innospec Ltd. (collectively, Innospec) which provided for mutual releases of the parties and a dismissal of the actions with prejudice. Under the settlement agreement, Innospec will pay NewMarket an aggregate amount of approximately $45 million in a combination of cash, a promissory note, and stock, of which $25 million was paid in cash on September 20, 2011 and approximately $5 million was paid in the form of 195,313 shares of unregistered Innospec Inc. common stock. Fifteen million dollars is payable in three equal annual installments of $5 million under the promissory note, which bears interest at 1% per year. The first installment is due on September 10, 2012. We recognized a pre-tax gain of $38.7 million, which is net of expenses related to the settlement of the lawsuit.

Results of Operations

Revenue

Our consolidated revenue for the third quarter 2011 amounted to $557.4 million, representing an increase of approximately 18% from the 2010 third quarter level of $471.8 million. Similarly, nine months consolidated revenue increased 23% from $1.3 billion for 2010 to $1.6 billion for 2011. The table below shows our revenue by segment.

Consolidated Revenue by Segment

(in millions)

	Third Quarter Ended September 30				Nine Months Ended September 30
	2011		2010		2011		2010
Petroleum additives	$	552.0	$	465.1	$	1,627.4	$	1,319.4

All other		2.6		3.8		8.0		8.7
Consolidated revenue	$	557.4	$	471.8	$	1,644.0	$	1,336.7

Petroleum Additives Segment

Petroleum additives net sales for the third quarter 2011 of $552.0 million increased $86.9 million, or approximately 19%, from $465.1 million for the third quarter 2010. The increase in sales when comparing the two third quarter periods primarily resulted from higher selling prices, as well as a favorable impact from foreign currency. When comparing the two periods, the U.S. Dollar weakened against the major currencies in which we conduct business, including the Euro and Pound Sterling, resulting in a favorable foreign currency impact on revenue from sales. Product shipments between the third quarter 2011 and third quarter 2010 were substantially unchanged. Nonetheless, sales were favorably impacted between the two quarters due to mix of product shipments resulting from increased shipments of certain higher priced products.

Nine months 2011 petroleum additive net sales of $1.6 billion were approximately 23% higher than nine months 2010. The increase between the two nine months periods reflects a 9% increase in product shipments. The increase in shipments was predominantly in the lubricant additives product line and included the benefit of the Polartech group of companies (Polartech) shipments for the full nine months 2011. Increased selling prices and a favorable foreign currency impact also contributed to the higher petroleum additives net sales when comparing the nine months periods between the two years.

37

The table below details the approximate components, in millions, of the increase between the third quarter and nine months of the 2011 and 2010 periods.

	Third Quarter		Nine Months
	(in millions)
Period ended September 30, 2010	$	465.1	$	1,319.4
Change in shipments, including changes in product mix		7.9		152.6
Increase in selling prices, including changes in customer mix		62.7		126.0
Increase due to foreign currency		16.3		29.4
Period ended September 30, 2011	$	552.0	$	1,627.4

Real Estate Development Segment

The revenue reflected in the table above for both third quarter and nine months 2011 and 2010 for the real estate development segment represents the rental of an office building, which was constructed by Foundry Park I.

All Other

The “All other” category includes the operations of the TEL business and certain contract manufacturing performed by Ethyl.

Segment Operating Profit

NewMarket evaluates the performance of the petroleum additives business and the real estate development business based on segment operating profit. NewMarket Services Corporation (NewMarket Services) expenses are charged to NewMarket and each subsidiary pursuant to service agreements between the companies. Depreciation on segment property, plant, and equipment, as well as amortization of segment intangible assets is included in segment operating profit.

The table below reports segment operating profit for the third quarter and nine months ended September 30, 2011 and September 30, 2010.

Petroleum Additives Segment

The petroleum additives segment includes a net gain of $38.7 million related to the Innospec legal settlement in 2011, which is discussed above in the Overview section. Including the legal settlement, the petroleum additives operating profit increased $42.8 million when comparing third quarter 2011 to third quarter 2010 and $61.9 million when comparing nine months 2011 to nine months 2010. When compared to 2010 operating profit levels for the third quarter, results were higher across the fuel additives product line, but substantially unchanged across the lubricant additives product line. For nine months 2011, results are higher across both the lubricant additives product line and the fuel additives product line when compared to nine months 2010.

Higher selling prices and the foreign currency impact, as discussed in the Revenue section above, were significant favorable factors in operating profit for both the third quarter and nine months 2011 as compared to the same 2010 periods. Substantially increased product shipments for nine months 2011 also favorably impacted operating profit compared to nine months 2010. The inclusion of the Polartech acquisition for the full nine months in 2011 further contributed to the improved operating results. Partially offsetting these favorable factors on operating profit, were unfavorable effects from increased raw material costs, as well as planned additional spending in selling, general, and administrative expenses (SG&A) and research, development, and testing expenses (R&D). In response to the rising raw material costs, we have been implementing selling price increases.

Our SG&A, together with R&D, were approximately $5.9 million, or 11.4%, higher for the third quarter 2011 as compared to third quarter 2010 and approximately $23.3 million, or 15.4%, higher for nine months 2011 as compared to nine months 2010. In 2011, SG&A increased approximately $1.8 million, or 6.0%, for the third quarter and $12.4 million, or 14.6%, for nine months over 2010 levels. The increase for both the third quarter and nine months 2011 over the same 2010 periods primarily reflects higher personnel-related costs and professional fees. The increase for nine months 2011 over nine months 2010 also included the result of certain growth-related costs, largely reflecting the inclusion of the Polartech operations for the full nine months in 2011. R&D increased approximately $4.1 million, or 18.3%, for third quarter 2011 and $10.9 million, or 16.5%, for nine months 2011 when compared to the same 2010 periods. We continue to invest in SG&A and R&D to support our customers’ programs and to develop the technology required to remain a leader in this industry.

The following discussion references the Consolidated Financial Statements beginning on page 3 of this Quarterly Report on Form 10-Q.

Interest and Financing Expenses

Interest and financing expenses were $4.8 million for third quarter 2011 and $4.5 million for third quarter 2010. Nine months 2011 amounted to $14.1 million, while nine months 2010 was $12.7 million.

The increase in interest and financing expenses between both the third quarter 2011 and nine months 2011 as compared to the same periods for 2010 was primarily related to higher average outstanding debt on the revolving credit facility during 2011, partially offset by a lower average interest rate as compared to the 2010 periods.

Other Expense, Net

Other expense, net for third quarter 2011 was $12.8 million, while third quarter 2010 was $5.5 million. The amount for nine months 2011 was $16.9 million, while nine months 2010 was $17.0 million. Nine months 2011 includes $1.0 million expense related to the consent we obtained in

39

January 2011 from the holders of the senior notes to modify the formula for calculating the capacity under the senior notes to make certain restricted payments. The remaining amounts for all periods in both 2011 and 2010 primarily reflect the loss on a derivative instrument representing an interest rate swap recorded at fair value through profit and loss. See Note 9 for additional information on the interest rate swap.

Income Tax Expense

Income tax expense was $31.9 million for third quarter 2011 and $21.9 million for third quarter 2010. The effective tax rate was 30.9% for third quarter 2011, while third quarter 2010 was 32.3%. The increase in income before income tax expense resulted in an increase of $11.5 million in income taxes, while the lower effective tax rate in 2011 as compared to 2010 resulted in a decrease of $1.5 million in income tax expense when comparing the two third quarter periods.

Income tax expense was $79.8 million for nine months 2011 and $62.8 million for nine months 2010. The effective tax rate was 31.6% for nine months 2011 and 33.0% for nine months 2010. The increase in income before income tax expense resulted in an increase of $20.6 million in income taxes, while the lower effective tax rate in 2011 as compared to 2010 resulted in a decrease of approximately $3.6 million in income taxes when comparing the nine months 2011 and 2010 periods.

The primary reason for the lower effective tax rate in the third quarter and nine months 2011 periods is due to the inclusion of the R&D credit in the current year, which was not available for the same 2010 periods, as well as a larger domestic manufacturing tax credit. Also, both current year periods include tax benefits due to foreign exchange fluctuations on previously taxed income, while both periods in 2010 included non-deductible expenses related to the Polartech acquisition.

Cash Flows, Financial Condition, and Liquidity

Cash and cash equivalents at September 30, 2011 were $54.5 million, which was an increase of $5.3 million since December 31, 2010 and included a $300 thousand unfavorable impact from foreign currency translation.

We expect that cash from operations, together with borrowings available under our revolving credit facility, will continue to be sufficient to cover our operating expenses for the foreseeable future.

40

Cash Flows – Operating Activities

Cash flows provided from operating activities for the nine months 2011 were $120.4 million and included a decrease of $88.4 million due to higher working capital levels, including higher accounts receivable and inventories, which were partially offset by higher accrued expenses and income taxes payable. The increase in accounts receivable is primarily due to higher sales levels when comparing the 2011 period with the fourth quarter 2010. The increase in inventories reflects increased quantities at certain locations to respond to demand for our products, as well as higher priced inventory at certain locations. The increase in accrued expenses is primarily related to stock repurchased at the end of the third quarter 2011, but paid in early October 2011, as well as higher interest due to timing of payments and higher professional fees. The fluctuation in income taxes payable reflects taxes due on earnings, which will be paid during 2011. Cash flows from operations also include a receipt of $25 million from the legal settlement with Innospec. Income taxes and professional fees associated with the settlement will be paid in the fourth quarter 2011. See Note 8 for additional information on the settlement.

Including cash and the current portion of long-term debt, we had working capital of $478.8 million at September 30, 2011 and $396.4 million at December 31, 2010. The current ratio was 3.01 to 1 at September 30, 2011 and 2.92 to 1 at December 31, 2010.

Cash Flows – Investing Activities

Cash used in investing activities was $58.4 million during nine months 2011 and included $42.8 million for capital expenditures. Also included in investing activities was a net deposit of $11.0 million and a net settlement payment of $4.9 million related to the Goldman Sachs interest rate swap. Further information on the interest rate swap is discussed in Note 9. We estimate our total capital spending during 2011 will be approximately $50 million. We expect to continue to finance capital spending through cash on hand and cash provided from operations, together with borrowing available under our $300 million revolving credit facility.

Cash Flows – Financing Activities

Cash used in financing activities during nine months 2011 amounted to $56.4 million. We borrowed an additional $51.0 million under our revolving credit facility during the nine months 2011. We also incurred $3.2 million of debt issuance costs related to the consents we obtained from the senior note holders related to the change in the formula for calculating the capacity to make restricted payments under the senior notes. In addition, we paid $85.9 million for the repurchase of common stock. We also paid $22.5 million to fund dividends during nine months 2011.

We had total long-term debt, including the current portion, of $276.0 million at September 30, 2011, representing an increase of approximately $54.1 million in our total debt since December 31, 2010. The increase resulted from borrowing an additional $51.0 million under the revolving credit facility, as well as an additional $5.3 million under foreign short-term lines of credit. These borrowings were partially offset by principal payments of approximately $2.0 million on the mortgage loan, as well as $100 thousand on capital leases.

At September 30, 2011, in addition to the revolving credit facility and the Foundry Park I mortgage loan, which are discussed below, we had outstanding senior notes in the aggregate principal amount of $150 million that bear interest at a fixed rate of 7.125% and are due in 2016. Two of our subsidiaries also have short-term lines of credit for working capital purposes. The line of credit for one of our subsidiaries in India is for 110 million Rupees and has an outstanding balance of 90 million Rupees or $1.8 million at September 30, 2011. The line of credit for one of our subsidiaries in China is for $5 million with an outstanding balance of $5.0 million at September 30, 2011.

41

At September 30, 2011, we also had a $300 million multicurrency revolving credit facility, with a $100 million sublimit for multicurrency borrowings and a $100 million sublimit for letters of credit. The agreement includes an expansion feature, which allows us, subject to certain conditions, to request to increase the aggregate amount of the revolving credit facility or obtain incremental term loans in an amount up to $150 million. Borrowings bear interest at variable rates. The facility matures on November 12, 2015. At September 30, 2011, we had $55.0 million of outstanding borrowings under the revolving credit facility. We had outstanding letters of credit of $6.4 million at September 30, 2011, resulting in the unused portion of the revolver amounting to $238.6 million.

Both the senior notes and the revolving credit facility contain covenants, representations, and events of default that management considers typical of credit agreements of this nature. We were in compliance with all covenants under both the senior notes and the revolving credit facility as of both September 30, 2011 and December 31, 2010.

The more restrictive and significant of the covenants under the senior notes include a minimum fixed charge coverage ratio of 2.00, as well as a limitation on restricted payments, as defined in the agreement. Our fixed charge coverage ratio was 21.62 at September 30, 2011 and 19.46 at December 31, 2010 under the senior notes. In addition, we would have been permitted to make additional restricted payments in the amount of approximately $120 million at September 30, 2011 and $50 million at December 31, 2010 under the senior notes. The increase in the capacity for restricted payments between December 31, 2010 and September 30, 2011 resulted from the January 2011 consents obtained from the holders of the senior notes allowing for a modification in the formula for calculating permitted restricted payments.

The more restrictive and significant financial covenants under the revolving credit facility include:

• An interest coverage ratio of no less than 3.00; and

• A leverage ratio of no more than 3.00.

At September 30, 2011, the interest coverage ratio was 18.69 and the leverage ratio was 0.76, while at December 31, 2010 the interest coverage ratio was 16.50 and the leverage ratio was 0.74.

As a percentage of total capitalization (total debt and shareholders’ equity), our total debt percentage increased from 31.1% at the end of 2010 to 33.2% at September 30, 2011. The change in the percentage was primarily the result of the increase in debt, partially offset by an increase in shareholders’ equity. The increase in shareholders’ equity reflects our earnings, partially offset by the impact of dividend payments and the repurchase of our common stock. Normally, we repay any outstanding long-term debt with cash from operations or refinancing activities.

Foundry Park I Mortgage Loan Agreement and Interest Rate Swap

On January 28, 2010, Foundry Park I entered into a mortgage loan agreement in the amount of $68.4 million. The loan, which is collateralized by the Foundry Park I office building, is for a period of five years, with two thirteen-month extension options. NewMarket Corporation is fully guaranteeing the loan. The mortgage loan bears interest at a variable rate of LIBOR plus a margin of 400 basis points, with a minimum LIBOR of 200 basis points. Concurrently with the closing of the mortgage loan, Foundry Park I obtained an interest rate swap to effectively convert the variable interest rate of the loan to a fixed interest rate by setting LIBOR at 2.642% for five years. The interest rate swap is discussed in Note 9. Principal payments on the loan are being made monthly based on a 15-year amortization schedule, with all remaining amounts due in January 2015, unless we exercise the extension option.

42

Critical Accounting Policies and Estimates

This report, as well as the 2010 Annual Report on Form 10-K, includes a discussion of our accounting principles, as well as methods and estimates used in the preparation of our financial statements. We believe these discussions and financial statements fairly represent the financial position and operating results of our company in all material respects. The purpose of this portion of our discussion is to further emphasize some of the more critical areas where a significant change in facts and circumstances in our operating and financial environment might cause a change in reported financial results.

Intangibles (Net of Amortization) and Goodwill

We have certain identifiable intangibles, as well as goodwill, amounting to $40.3 million at September 30, 2011. These intangibles relate to our petroleum additives business and, except for the goodwill, are being amortized over periods with up to approximately twenty years of remaining life. We continue to assess the market related to these intangibles, as well as their specific values, and have concluded the values and amortization periods are appropriate. We also evaluate these intangibles for any potential impairment when significant events or circumstances occur that might impair the value of these assets. These evaluations continue to support the value at which these identifiable intangibles are carried on our financial statements. However, if conditions were to substantially deteriorate in this market, it could possibly cause a reduction in the periods of the amortization charge or result in a noncash write-off of a portion of the intangibles’ carrying value. A reduction in the amortization period would have no effect on cash flows. We do not anticipate such a change in the market conditions.

Environmental and Legal Proceedings

We believe our environmental accruals are appropriate for the exposures and regulatory guidelines under which we currently operate. While we currently do not anticipate significant changes to the many factors that could impact our environmental requirements, we continue to keep our accruals consistent with these requirements as they change.

While it is not possible to predict or determine with certainty the outcome of any legal proceeding, it is our opinion, based on our current knowledge, that we will not experience materially adverse effects on our results of operations, financial condition, or cash flows as a result of any pending or threatened proceeding.

Pension Plans and Other Postretirement Benefits

We use assumptions to record the impact of the pension and postretirement plans in the financial statements. These assumptions include the discount rate, expected long-term rate of return on plan assets, rate of compensation increase, and health care cost trend rate. A change in any one of these assumptions could result in different results for the plans. We develop these assumptions after considering available information that we deem relevant. Information is provided on the pension and postretirement plans in Note 19 of the 2010 Annual Report. In addition, further disclosure on the effect of changes in these assumptions is provided in the “Financial Position and Liquidity” section of Part II, Item 7 of the 2010 Annual Report.

Income Taxes

We file consolidated U.S. federal income and both consolidated and individual state income tax returns, as well as individual foreign income tax returns, under which assumptions may be made to determine the deductibility of certain costs. We make estimates related to the impact of tax

43

positions taken on our financial statements when we believe the tax position is more likely than not to be upheld on audit. In addition, we make certain assumptions in the determination of the estimated future recovery of deferred tax assets.

Recently Issued Accounting Pronouncements

For a full discussion of the more significant pronouncements which may impact our financial statements, see Note 13.

Outlook

We are very pleased with the performance of our business during the first three quarters of 2011. Our businesses continue to run well and we remain focused on providing the goods and services our customers expect of us. The overall industry dynamics remained fairly constant during the first nine months of 2011, and we anticipate no change in the near term. The third quarter exhibited a slowdown in the rate of increase in the demand for our products, and we expect that lower rate will continue into the fourth quarter. We look forward to a successful and profitable 2011.

Our balance sheet is strong, our business continues to generate cash, and we have significant debt capacity to support the expansion and growth aspirations of our businesses. We have increased our efforts in investigating potential acquisitions as both a use of this cash and debt capacity and to generate shareholder value. Our primary focus in the acquisition area remains on the petroleum additives industry. It is our view that this industry will provide the greatest opportunity for a good return on our investment while minimizing risk. We remain focused on this strategy and will evaluate any future opportunities. Nonetheless, we are patient in this pursuit and intend to make the right acquisition when the opportunity arises. Until an acquisition materializes, we will continue to evaluate all alternative uses of our cash to enhance shareholder value, including stock repurchases and dividends.

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

Except as disclosed below, there have been no significant changes in our market risk from the information provided in the 2010 Annual Report.

As part of the legal settlement related to the Innospec lawsuit, we own 195,313 shares of unregistered Innospec Inc. common stock. We have classified the stock as available for sale and have recorded the stock in current assets at a fair market value discounted for transfer restrictions on the shares. The unrealized gain or loss on the common stock is recorded in Other Comprehensive Income. At September 30, 2011, we valued the stock at $4.5 million. A hypothetical 10% decrease in the stock price, holding all other variables constant, would have resulted in a decrease of approximately $400 thousand in the fair value of the stock at September 30, 2011.

ITEM 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain a system of internal control over financial reporting to provide reasonable, but not absolute, assurance of the reliability of the financial records and the protection of assets. Our controls and procedures include written policies and procedures, careful selection and training of qualified personnel, and an internal audit program. We use a third-party firm, separate from our independent registered public accounting firm, to assist with internal audit services.

We work closely with the business groups, operations personnel, and information technology to ensure transactions are recorded properly. Environmental and legal staff are consulted to determine the appropriateness of our environmental and legal liabilities for each reporting period. We regularly review the regulations and rule changes that affect our financial disclosures.

Our disclosure control procedures include signed representation letters from our regional officers, as well as senior management.

We have formed a Financial Disclosure Committee (the committee), which is made up of the president of Afton Chemical Corporation, the general counsel of NewMarket, and the controller of NewMarket. The committee, as well as regional management, makes representations with regard to the financial statements that, to the best of their knowledge, the report does not contain any misstatement of a material fact or omit a material fact that is necessary to make the statements not misleading with respect to the periods covered by the report.

The committee and the regional management also represent, to the best of their knowledge, that the financial statements and other financial information included in the report fairly present, in all material respects, the financial condition, results of operations and cash flows of the company as of and for the periods presented in the report.

Pursuant to Rule 13a-15(b) under the Securities Exchange Act of 1934 (the Exchange Act), we carried out an evaluation, with the participation of our management, including our principal executive officer and our principal financial officer, of the effectiveness of our disclosure controls and procedures (as defined under Rule 13a-15(e)) under the Exchange Act as of the end of the period covered by this report. Based upon that evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures are effective.

45

Changes in Internal Controls Over Financial Reporting

There has been no change in our internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act, during the quarter ended September 30, 2011, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

46

PART II – OTHER INFORMATION

ITEM 1. Legal Proceedings

We are involved in legal proceedings that are incidental to our business and include administrative or judicial actions seeking remediation under environmental laws, such as Superfund. Some of these legal proceedings relate to environmental matters and involve governmental authorities. For further information, see “Environmental” in Part I, Item 1 of our 2010 Annual Report and Note 8 in this Form 10-Q.

While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

As previously disclosed, NewMarket Corporation and Afton Chemical Corporation (collectively, NewMarket) brought two civil actions against Innospec Inc. and its subsidiaries Alcor Chemie Vertriebs GmbH and Innospec Ltd. (collectively Innospec) in July 2010.

NewMarket and Innospec have agreed to settle these actions pursuant to the terms of a settlement agreement between them signed on September 13, 2011 which provides for mutual releases of the parties and dismissal of the actions with prejudice. Under the settlement agreement, Innospec will pay NewMarket an aggregate amount of approximately $45 million, payable in a combination of cash, a promissory note, and stock, of which $25 million was paid in cash on September 20, 2011 and approximately $5 million was paid in the form of 195,313 shares of unregistered Innospec Inc. common stock. Fifteen million dollars is payable in three equal annual installments of $5 million under the promissory note, which bears interest at 1% per year. The first installment is due on September 10, 2012.

47

ITEM 2. Unregistered Sales of Equity Securities and Use of Proceeds

On July 21, 2010, our Board of Directors approved a share repurchase program authorizing management to repurchase up to $200 million of NewMarket Corporation’s outstanding common stock until December 31, 2012, as market conditions warrant and covenants under our existing agreements permit. We may conduct the share repurchases in the open market and in privately negotiated transactions. The repurchase program does not require NewMarket to acquire any specific number of shares and may be terminated or suspended at any time. Approximately $60 million remained available under the 2010 authorization at September 30, 2011. The following table outlines the purchases during the third quarter 2011 under this authorization.

(a) For both third quarter 2011 and nine months 2011, the petroleum additives segment includes a net gain of $38.7 million related to a legal settlement. On September 13, 2011, we signed a settlement agreement with Innospec Inc. and its subsidiaries, Alcor Chemie Vertriebs GmbH and Innospec Ltd. (collectively, Innospec) which provided for mutual releases of the parties and a dismissal of the actions with prejudice. Under the settlement agreement, Innospec will pay NewMarket an aggregate amount of approximately $45 million in a combination of cash, a promissory note, and stock, of which $25 million was paid in cash on September 20, 2011 and approximately $5 million was paid in the form of 195,313 shares of unregistered Innospec Inc. common stock. Fifteen million dollars is payable in three equal annual installments of $5 million under the promissory note, which bears simple interest at 1% per year. The first installment is due on September 10, 2012. The gain is net of expenses related to the settlement of the lawsuit.

(b) The loss on the interest rate swap agreement represents the change, since the beginning of the reporting period, in the fair value of an interest rate swap which we entered into on June 25, 2009. We are not using hedge accounting to record the interest rate swap, and accordingly, any change in the fair value is immediately recognized in earnings.

Derivatives And Hedging Activities [Abstract]

Derivatives And Hedging Activities

9. Derivatives and Hedging Activities

Accounting Policy for Derivative Instruments and Hedging Activities

We record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. We may enter into derivative contracts that are intended to economically hedge certain of our risks, even though hedge accounting does not apply or we elect not to apply hedge accounting. We do not enter into derivative instruments for speculative purposes.

Risk Management Objective of Using Derivatives

We are exposed to certain risks arising from both our business operations and economic conditions. We primarily manage our exposures to a wide variety of business and operational risks through management of our core business activities.

We manage certain economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of our debt funding, as well as through the use of derivative financial instruments. Specifically, we have entered into interest rate swaps to manage our exposure to interest rate movements.

Our foreign operations expose us to fluctuations of foreign exchange rates. These fluctuations may impact the value of our cash receipts and payments as compared to our reporting currency, the U.S. Dollar. To manage this exposure, we sometimes enter into foreign currency forward contracts to minimize currency exposure due to cash flows from foreign operations.

Cash Flow Hedge of Interest Rate Risk

In January 2010, we entered into an interest rate swap to manage our exposure to interest rate movements on the Foundry Park I mortgage loan and to reduce variability in interest expense. Further information on the mortgage loan is in Note 12 in our 2010 Annual Report. We also had an interest rate swap to manage our exposure to interest rate movements on the Foundry Park I construction loan and add stability to capitalized interest expense. The Foundry Park I construction loan interest rate swap matured on January 1, 2010. Both interest rate swaps are designated and qualify as a cash flow hedge. As such, the effective portion of changes in the fair value of the swaps is recorded in accumulated other comprehensive loss and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Any ineffective portion of changes in the fair value of the swap is recognized immediately in earnings. We assess the effectiveness of the mortgage loan interest rate swap quarterly by comparing the changes in the fair value of the derivative hedging instrument with the change in present value of the expected future cash flows of the hedged transaction.

The mortgage loan interest rate swap involves the receipt of variable-rate amounts based on LIBOR in exchange for fixed-rate payments over the life of the agreement without exchange of the underlying notional amount. The fixed-rate payments are at a rate of 2.642% for the mortgage loan interest rate swap. The notional amount of the mortgage loan interest rate swap was $68.4 million at origination and approximately $64.2 million at September 30, 2011. The notional amount of the mortgage loan interest rate swap amortizes to approximately $53.7 million over the term of the swap. The amortizing notional amount is necessary to maintain the swap notional at an amount that matches the declining mortgage loan principal balance over the loan term. The mortgage loan interest swap matures on January 29, 2015.

The unrealized loss, net of tax, related to the fair value of the mortgage loan interest rate swap is recorded in accumulated other comprehensive loss in shareholders' equity on the Consolidated Balance Sheets, and amounted to approximately $2.3 million at September 30, 2011 and $1.5 million at December 31, 2010. Also recorded as a component of accumulated other comprehensive loss in shareholders' equity on the Consolidated Balance Sheets is the accumulated losses related to the construction loan interest rate swap of approximately $2.6 million, net of tax, at both September 30, 2011 and December 31, 2010. The amount remaining in accumulated other comprehensive loss related to the construction loan interest rate swap is being recognized in the Consolidated Statements of Income over the depreciable life of the office building. Approximately $900 thousand, net of tax, currently recognized in accumulated other comprehensive loss related to both the construction loan interest rate swap and the mortgage loan interest rate swap is expected to be reclassified into earnings over the next twelve months.

Non-designated Hedges

On June 25, 2009, we entered into an interest rate swap with Goldman Sachs in the notional amount of $97 million and with a maturity date of January 19, 2022 (Goldman Sachs interest rate swap). NewMarket entered into the Goldman Sachs interest rate swap in connection with the termination of a loan application and related rate lock agreement between Foundry Park I and Principal Commercial Funding II, LLC (Principal). When the rate lock agreement was originally executed in 2007, Principal simultaneously entered into an interest rate swap with a third party to hedge Principal's exposure to fluctuation in the ten-year United States Treasury Bond rate. Upon the termination on June 25, 2009 of the rate lock agreement, Goldman Sachs both assumed Principal's position with the third party and entered into an offsetting interest rate swap with NewMarket. Under the terms of this interest rate swap, NewMarket will make fixed rate payments at 5.3075% and Goldman Sachs will make variable rate payments based on three-month LIBOR. We have collateralized this exposure through cash deposits posted with Goldman Sachs amounting to $34.2 million at September 30, 2011. This transaction effectively preserves the impact of the original rate lock agreement for the possible application to a future loan of a similar structure.

We do not use hedge accounting for the Goldman Sachs interest rate swap, and therefore, immediately recognize any change in the fair value of this derivative financial instrument in earnings.

Credit-risk-related Contingent Features

We have agreements with both of our current derivative counterparties that contain a provision where we could be declared in default on our derivative obligations if repayment of indebtedness is accelerated by our lender(s) due to our default on the indebtedness.

As of September 30, 2011, the fair value of derivatives in a net liability position related to these agreements, which includes accrued interest but excludes any adjustment for nonperformance risk, was $34.1 million. We have minimum collateral posting thresholds with one of our derivative counterparties and have posted cash collateral of $34.2 million as of September 30, 2011. If required, we could have settled our obligations under the agreements at their termination value of $34.1 million at September 30, 2011.

11. Fair Value Measurements

The following table provides information on assets and liabilities measured at fair value on a recurring basis. No events occurred during the nine months ended September 30, 2011, requiring adjustment to the recognized balances of assets or liabilities, which are recorded at fair value on a nonrecurring basis.

We determine the fair value of the derivative instruments shown in the table above by using widely-accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each instrument. The analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs.

The fair value of the interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments are based on an expectation of future interest rates derived from observable market interest rate curves. In determining the fair value measurements, we incorporate credit valuation adjustments to appropriately reflect both our nonperformance risk and the counterparties' nonperformance risk.

Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustment associated with the derivatives utilizes Level 3 inputs. These Level 3 inputs include estimates of current credit spreads to evaluate the likelihood of default by both us and the counterparties to the derivatives. We have assessed the significance of the impact of the credit valuation adjustment and determined the credit valuation adjustment is not significant to the overall valuation of the derivatives. Accordingly, we have determined that our derivative valuations should be classified in Level 2 of the fair value hierarchy.

The marketable securities in the table above represent the 195,313 shares of unregistered Innospec Inc. common stock that we own. See Note 8 for further information. The fair value of the common stock is determined using the closing market price of Innospec common stock at September 30, 2011, discounted for transfer restrictions on the shares. While the Innospec common stock is traded on a national exchange and the market price is a Level 1 input in the fair value hierarchy, the discount factor utilizes Level 3 inputs. We have assessed the significance of the impact of the discount factor adjustment on the overall valuation of the marketable securities and have determined that it is not significant to the overall valuation of the marketable securities. Accordingly, we have determined that our marketable securities valuation should be classified in Level 2 of the fair value hierarchy as the valuation relies on quoted prices for similar assets in an active market.

We record the value of our long-term debt at historical cost. The estimated fair value of our long-term debt is shown in the table below and is based primarily on estimated current rates available to us for debt of the same remaining duration and adjusted for nonperformance risk and credit risk. The fair value is categorized as Level 2.

Basic and diluted earnings per share are calculated as shown in the table below. Options are not included in the computation of diluted earnings per share when the option exercise price exceeds the average market price of the underlying common share, as the impact on earnings per share would be anti-dilutive. We had no anti-dilutive options that were excluded from the calculation of earnings per share for any period presented.

[1] The loss on the interest rate swap agreement represents the change, since the beginning of the reporting period, in the fair value of an interest rate swap which we entered into on June 25, 2009. We are not using hedge accounting to record the interest rate swap, and accordingly, any change in the fair value is immediately recognized in earnings.

1. Financial Statement Presentation

In the opinion of management, the accompanying consolidated financial statements of NewMarket Corporation and its subsidiaries contain all necessary adjustments for the fair statement of, in all material respects, our consolidated financial position as of September 30, 2011 and December 31, 2010, and the change in our shareholders' equity for the nine months ended September 30, 2011 and the year ended December 31, 2010, as well as our consolidated results of operations for the third quarter and nine months ended September 30, 2011 and September 30, 2010 and our cash flows for the nine months ended September 30, 2011 and September 30, 2010. All adjustments are of a normal, recurring nature, unless otherwise disclosed. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the NewMarket Corporation Annual Report on Form 10-K for the year ended December 31, 2010 (2010 Annual Report), as filed with the Securities and Exchange Commission (SEC). The results of operations for the nine month period ended September 30, 2011 are not necessarily indicative of the results to be expected for the full year ending December 31, 2011. The December 31, 2010 consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

Unless the context otherwise requires, all references to "we," "us," "our," the "Company" and "NewMarket" are to NewMarket Corporation and its consolidated subsidiaries.

Certain reclassifications have been made to the accompanying consolidated financial statements and the related notes to conform to the current presentation.

At both September 30, 2011 and December 31, 2010, we had a book overdraft for some of our disbursement cash accounts. A book overdraft represents transactions that have not cleared the bank accounts at the end of the reporting period. There are no agreements with the same banks to offset the presented balance. We transfer cash on an as-needed basis to fund these items as they clear the bank in subsequent periods.

Cash dividends for the nine months ended September 30, 2011 and September 30, 2010 were declared and paid as shown in the table below.

Year	Date Declared	Date Paid	Per Share Amount

Under the settlement agreement, Innospec will pay NewMarket an aggregate amount of approximately $45 million in a combination of cash, a promissory note, and stock, of which $25 million was paid in cash on September 20, 2011 and approximately $5 million was paid in the form of 195,313 shares of unregistered Innospec Inc. common stock. Fifteen million dollars is payable in three equal annual installments of $5 million under the promissory note, which bears simple interest at 1% per year. The first installment is due on September 10, 2012. The gain is net of expenses related to the settlement of the lawsuit.

(b) The loss on the interest rate swap agreement represents the change, since the beginning of the reporting period, in the fair value of an interest rate swap which we entered into on June 25, 2009. We are not using hedge accounting to record the interest rate swap, and accordingly, any change in the fair value is immediately recognized in earnings.

13. Recently Issued Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2011-08, "Intangibles – Goodwill and Other (Topic 350)" (ASU 2011-08). ASU 2011-08 simplifies goodwill impairment testing by allowing an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. An entity is no longer required to determine the fair value of a reporting unit unless it is more likely than not that the fair value is less than carrying value. ASU 2011-08 is effective for interim and annual periods beginning after December 15, 2011. Early adoption is permitted. We are evaluating the provisions of ASU 2011-08 and will apply its provisions by the beginning of the first quarter 2012.

In June 2011, the FASB issued Accounting Standards Update 2011-05, "Comprehensive Income (Topic 220) – Presentation of Comprehensive Income" (ASU 2011-05). ASU 2011-05 requires that all nonowner changes in stockholders' equity be presented either in a single continuous consolidated statement of comprehensive income or in two separate, but consecutive, consolidated statements of income and consolidated statements of comprehensive income. The option to present comprehensive income as part of the consolidated statement of stockholders' equity has been eliminated. ASU 2011-05 is effective for interim and annual periods beginning after December 15, 2011 and will be applied retrospectively. We will modify our financial statements beginning with our March 31, 2012 Quarterly Report on Form 10-Q to adopt the requirements.

In May 2011, the FASB issued Accounting Standards Update 2011-04, "Fair Value Measurement (Topic 820) – Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs" (ASU 2011-04). ASU 2011-04 results in common fair value measurement, as well as disclosure requirements, under U.S. GAAP and IFRS. The amendments clarify guidance on measuring fair value, but do not require any additional fair value measurements. ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011. Early application is not permitted. We do not expect ASU 2011-04 will have a significant impact on our financial statements.

Contractual Commitments And Contingencies

Contractual Commitments And Contingencies [Abstract]

Contractual Commitments And Contingencies

8. Contractual Commitments and Contingencies

There have been no significant changes in our contractual commitments and contingencies from those reported in our 2010 Annual Report on Form 10-K in Note 18, except as discussed below. The information below provides information on certain contractual commitments and contingencies.

Litigation

We are involved in legal proceedings that are incidental to our business and include administrative or judicial actions seeking remediation under environmental laws, such as Superfund. Some of these legal proceedings relate to environmental matters and involve governmental authorities. For further information, see "Environmental" below.

While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated financial condition, results of operations, or cash flows.

As previously disclosed, NewMarket Corporation and Afton Chemical Corporation (collectively, NewMarket) brought two civil actions against Innospec Inc. and its subsidiaries Alcor Chemie Vertriebs GmbH and Innospec Ltd. (collectively, Innospec) in July 2010.

NewMarket and Innospec have agreed to settle these actions pursuant to the terms of a settlement agreement between them signed on September 13, 2011 which provides for mutual releases of the parties and dismissal of the actions with prejudice. Under the settlement agreement, Innospec will pay NewMarket an aggregate amount of approximately $45 million, payable in a combination of cash, a promissory note, and stock, of which $25 million was paid in cash on September 20, 2011 and approximately $5 million was paid in the form of 195,313 shares of unregistered Innospec Inc. common stock. Fifteen million dollars is payable in three equal annual installments of $5 million under the promissory note, which bears interest at 1% per year. The first installment is due on September 10, 2012.

Environmental

During 2000, the U.S. Environmental Protection Agency (EPA) named us as a potentially responsible party (PRP) under Superfund law for the clean-up of soil and groundwater contamination at the Sauget Area 2 Site in Sauget, Illinois. Without admitting any fact, responsibility, fault, or liability in connection with this site, we are participating with other PRPs in site investigations and feasibility studies. The Sauget Area 2 Site PRPs received notice of approval from the EPA of their October 2009 Human Health Risk Assessment. Additionally, the PRPs have submitted their Feasibility Study (FS) to the EPA Remedy Review Board. We have accrued our estimated proportional share of the expenses for the FS, as well as our best estimate of our proportional share of the remediation liability proposed in our ongoing discussions and submissions with the agencies involved. The amount currently accrued for this site is not material.

At a former TEL plant site located in Louisiana, we have completed significant environmental remediation, although we will be monitoring and treating the site for an extended period. The accrual for this site was $6.3 million at September 30, 2011 and $6.8 million at December 31, 2010. We based these amounts on the best estimate of future costs discounted at approximately 3% in both 2011 and 2010. An inflation factor is included in the estimate. The undiscounted liability was $8.1 million at September 30, 2011 and $8.7 million at December 31, 2010. The expected payments over the next five years amount to approximately $200 thousand in 2011, $700 thousand in 2012, and $600 thousand for each of the years 2013 through 2015. Expected payments thereafter amount to approximately $5.4 million.

At a plant site in Houston, Texas, we have accruals of $7.5 million at September 30, 2011 and $7.6 million at December 31, 2010 for environmental remediation, dismantling, and decontamination. Included in these amounts are $6.8 million at September 30, 2011 and $7.3 million at December 31, 2010 for remediation. Of the total remediation, $6.5 million at September 30, 2011 and $6.9 million at December 31, 2010 relates to remediation of groundwater and soil. The accruals for this site are discounted at approximately 3% at both September 30, 2011 and December 31, 2010 and include an inflation factor. The undiscounted accrual for this site was $10.5 million at September 30, 2011 and $10.8 million at December 31, 2010. The expected payments over the next five years are approximately $1.0 million in 2012, $500 thousand in 2013, $1.7 million in 2014, and $200 thousand in 2015. Expected payments thereafter amount to approximately $7.1 million.

At a Superfund site in Louisiana, we have an accrual of $3.3 million at both September 30, 2011 and December 31, 2010 for environmental remediation. The accrual for this site was discounted at approximately 3% at both September 30, 2011 and December 31, 2010 and included an inflation factor. The undiscounted accrual for this site was $4.2 million at both September 30, 2011 and December 31, 2010. The expected payments over the next five years amount to approximately $100 thousand in 2011, $300 thousand in 2012, $200 thousand in 2013, and $300 thousand each for years 2014 and 2015. Expected payments thereafter amount to approximately $3.0 million.

The remaining environmental liabilities are not discounted.

We accrue for environmental remediation and monitoring activities for which costs can be reasonably estimated and are probable. These estimates are based on an assessment of the site, available clean-up methods, and prior experience in handling remediation. While we believe we are currently fully accrued for known environmental issues, it is possible that unexpected future costs could have a significant impact on our financial position, results of operations, and cash flows.

Our total accruals for environmental remediation were approximately $22.2 million at September 30, 2011 and $22.5 million at December 31, 2010. In addition to the accruals for environmental remediation, we also have accruals for dismantling and decommissioning costs of $600 thousand at September 30, 2011 and $500 thousand at December 31, 2010.

Letters of Credit and Guarantees

We have outstanding guarantees with several financial institutions in the amount of $56.5 million at September 30, 2011. The guarantees are secured by letters of credit, as well as cash collateral. A portion of the guarantees is unsecured. The outstanding letters of credit amounted to $6.4 million at September 30, 2011, all of which were issued under the letter of credit sub-facility of our revolving credit facility. The letters of credit primarily relate to insurance and performance guarantees. The remaining amounts represent additional performance, lease, custom and excise tax guarantees, as well as a cash deposit of $34.2 million related to the Goldman Sachs Bank USA (Goldman Sachs) interest rate swap. The cash deposit is recorded in "Other assets and deferred charges" on the Consolidated Balance Sheets. Expiration dates of the letters of credit and certain guarantees range from 2011 to 2014. Some of the guarantees have no expiration date. We renew letters of credit as necessary.

We cannot estimate the maximum amount of potential liability under the guarantees. However, we accrue for potential liabilities when a future payment is probable and the range of loss can be reasonably estimated.

Consolidating Financial Information [Abstract]

Consolidating Financial Information

12. Consolidating Financial Information

The 7.125% senior notes due 2016 (senior notes) are guaranteed by certain of our subsidiaries (Guarantor Subsidiaries) on a joint and several unsecured senior basis. The senior notes include a provision which allows for a Guarantor Subsidiary to be released of any obligation under the subsidiary guarantee under certain conditions. Those conditions include the sale or other disposition of all or substantially all of the Guarantor Subsidiary's assets. The Guarantor Subsidiaries include all of our existing and future 100% owned domestic restricted subsidiaries. The Guarantor Subsidiaries and the subsidiaries that do not guarantee the senior notes (the Non-Guarantor Subsidiaries) are 100% owned by NewMarket Corporation (the Parent Company). The Guarantor Subsidiaries consist of the following:

Ethyl Corporation	Afton Chemical Corporation
Ethyl Asia Pacific LLC	Afton Chemical Asia Pacific LLC
Ethyl Canada Holdings, Inc.	Afton Chemical Canada Holdings, Inc.

Ethyl Export Corporation	Afton Chemical Japan Holdings, Inc.
Ethyl Interamerica Corporation	Afton Chemical Additives Corporation
Ethyl Ventures, Inc.	Afton Chemical Intangibles LLC
Interamerica Terminals Corporation	The Edwin Cooper Corporation
NewMarket Development Corporation	NewMarket Investment Company
NewMarket Services Corporation	Old Town LLC
Foundry Park I, LLC	Foundry Park II, LLC
Gamble's Hill, LLC	Gamble's Hill Lab, LLC
Gamble's Hill Landing, LLC	Gamble's Hill Third Street, LLC
Gamble's Hill Tredegar, LLC

We conduct all of our business and derive essentially all of our income from our subsidiaries. Therefore, our ability to make payments on the senior notes or other obligations is dependent on the earnings and the distribution of funds from our subsidiaries. There are no restrictions on the ability of any of our domestic subsidiaries to transfer funds to the Parent Company.

The following sets forth the Consolidating Statements of Income for the third quarter and nine months ended September 30, 2011 and September 30, 2010; Consolidating Balance Sheets as of September 30, 2011 and December 31, 2010; and Condensed Consolidating Statements of Cash Flows for the nine months ended September 30, 2011 and September 30, 2010 for the Parent Company, the Guarantor Subsidiaries, and Non-Guarantor Subsidiaries. The financial information is based on our understanding of the SEC's interpretation and application of Rule 3-10 of the SEC Regulation S-X.

The financial information may not necessarily be indicative of their results of operations or financial positions had the Guarantor Subsidiaries or Non-Guarantor Subsidiaries operated as independent entities. The Parent Company accounts for investments in these subsidiaries using the equity method.

[1] The loss on the interest rate swap agreement represents the change, since the beginning of the reporting period, in the fair value of an interest rate swap which we entered into on June 25, 2009. We are not using hedge accounting to record the interest rate swap, and accordingly, any change in the fair value is immediately recognized in earnings.

[2] For both third quarter 2011 and nine months 2011, the petroleum additives segment includes a net gain of $38.7 million related to a legal settlement. On September 13, 2011, we signed a settlement agreement with Innospec Inc. and its subsidiaries, Alcor Chemie Vertriebs GmbH and Innospec Ltd. (collectively, Innospec) which provided for mutual releases of the parties and a dismissal of the actions with prejudice. Under the settlement agreement, Innospec will pay NewMarket an aggregate amount of approximately $45 million in a combination of cash, a promissory note, and stock, of which $25 million was paid in cash on September 20, 2011 and approximately $5 million was paid in the form of 195,313 shares of unregistered Innospec Inc. common stock. Fifteen million dollars is payable in three equal annual installments of $5 million under the promissory note, which bears simple interest at 1% per year. The first installment is due on September 10, 2012. The gain is net of expenses related to the settlement of the lawsuit.
