Note 1:           SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Company Operations

We, AMCOL International Corporation (the “Company”), are a global company focused on long-term profitability growth through the development and application of minerals and technology products and services for use in various industrial and consumer markets. We operate in five segments: minerals and materials, environmental, oilfield services, transportation and corporate.

Our minerals and materials segment mines, processes and distributes minerals and products for use in various industrial and consumer markets, including metalcasting, pet care, laundry care, and drilling industries. Additionally, this segment develops and manufactures synthetic materials principally for personal care applications.

Our environmental segment manufactures and distributes products for use as moisture and vapor barriers in commercial construction, landfills and a variety of other industrial and commercial applications and provides related services.

Our oilfield services segment provides both onshore and offshore water treatment filtration, well testing, pipeline separation, nitrogen, coil tubing and other services to the oil and natural gas industry.

Our transportation segment includes both a long-haul trucking business and a freight brokerage business serving our domestic subsidiaries as well as third parties.

Our corporate segment includes the elimination of intersegment sales as well as certain expenses associated with research and development, management, employee benefits and information technology activities for our Company. Approximately 71% and 82% of the revenue elimination in the three months ended March 31, 2012 and 2011, respectively, represents elimination of shipping revenues between our transportation segment and its domestic sister companies.

The composition of our revenues by segment is as follows:

	Three Months Ended March 31,
	2012	2011
Minerals and materials	53%	53%
Environmental	22%	24%
Oilfield services	23%	21%
Transportation	5%	6%
Intersegment sales	-3%	-4%
	100%	100%

Further discussion of our segment information is included in Note 4, “Business Segment Information.”

Basis of Presentation

The financial information included herein has been prepared by management, and other than the condensed consolidated balance sheet as of December 31, 2011, is unaudited. The condensed consolidated balance sheet as of December 31, 2011 has been derived from, but does not include all of the disclosures contained in, the audited consolidated financial statements for the year ended December 31, 2011. The information furnished herein includes all adjustments that are, in our opinion, necessary for a fair presentation of our results of operations and cash flows for the interim periods ended March 31, 2012 and 2011, and our financial position as of March 31, 2012, and all such adjustments are of a normal and recurring nature. The accompanying condensed consolidated financial information should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2011.

Certain items in the prior year’s condensed consolidated financial statements contained herein and notes thereto have been reclassified to conform to the condensed consolidated financial statement presentation for the three months ended March 31, 2012. These reclassifications did not have a material impact on our financial statements.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year for a variety of reasons, including the seasonality of both our environmental segment, which varies due to the seasonal nature of the construction industry, and our oilfield services segment, which varies due to seasonal weather patterns in its various geographic markets.

Note 2:          EARNINGS PER SHARE

The following table provides further share information used in computing our earnings per share for the periods presented herein. Basic earnings per share was computed by dividing net income attributable to AMCOL shareholders by the weighted average number of common shares outstanding during each period. Diluted earnings per share was computed by dividing net income attributable to AMCOL shareholders by the weighted average common shares outstanding after consideration of the dilutive effect of stock compensation awards outstanding during each period.

maker, our President and Chief Executive Officer, in deciding how to allocate resources and in assessing performance. Intersegment sales are not material and are eliminated in the corporate segment. Our reportable measure of profit or loss for each segment is operating profit, which is defined as net sales less cost of sales and selling, general and administrative expenses related to a segment’s operations. The costs deducted to arrive at operating profit do not include several items, such as net interest expense or income taxes. Segment assets are those assets used in the operations of that segment. Corporate assets include assets used in the operation of this segment as well as those used by or shared amongst our segments, including certain cash and equivalent assets, certain fixed assets, assets associated with certain employee benefit plans, and other miscellaneous assets.

Note 6:          INCOME TAXES

Our effective tax rate for the three months ended March 31, 2012 and 2011 was 28.7% and 27.7%, respectively. For both periods, the rate differs from the U.S. federal statutory rate of 35.0% largely due to depletion deductions, changes in tax reserves in 2011, and differences in local tax rates on the income from our foreign subsidiaries.

In the normal course of business, we are subject to examination by taxing authorities throughout the world. With few exceptions, we are no longer subject to income tax examinations by tax authorities for years prior to 2004. In general, the United States Internal Revenue Service (“IRS”) has examined our federal income tax returns for all years through 2009.

Note 7:          DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

As a multinational corporation with operations throughout the world, we are subject to certain market risks. We use a variety of practices to manage these market risks, including, when considered appropriate, derivative financial instruments. We use derivative financial instruments only for risk management and not for trading or speculative purposes.

The following table sets forth the fair values of our derivative instruments and where they are recorded within our condensed consolidated balance sheet:

Liability Derivatives	Balance Sheet Location	Fair Value as of
		March 31, 2012			December 31, 2011
Derivatives designated as hedging instruments:
Interest rate swaps	Other long-term liabilities	$	(8.7	)	$	(9.0	)

	Three Months Ended March 31,
	2012		2011
Interest rate swaps, net of tax	$	0.2	$	0.5

We use interest rate swaps to manage floating interest rate risk on debt securities. Interest rate differentials are paid or received on these arrangements over the life of the swap. As of March 31, 2012 and 2011, we had interest rate swaps outstanding which effectively hedge the variable interest rate on

Other

We are exposed to potential gains or losses from foreign currency fluctuations affecting net investments and earnings denominated in foreign currencies. We are particularly sensitive to currency exchange rate fluctuations between the following currency pairs: a) the Euro to the British pound (GBP) and the Polish Zloty (PLN), b) the South African Rand (ZAR) to the USD and the Australian dollar (AUD), c) the GBP to the Danish kroner (DKK) and the Swiss franc (SEK), and d) the USD to the Indian rupee (INR), the Thai baht (THB), and the Turkish lira (TRY). When considered appropriate, we enter into foreign exchange derivative contracts to mitigate the risk of fluctuations on these exposures.

We have not designated our foreign currency derivative contracts for hedge accounting treatment and therefore, changes in fair value of these contracts are recorded in earnings as follows:

Derivatives Not Designated as Hedging Instruments	Location of  Gain or (Loss) Recognized in Income on Derivatives	Amount of Gain or (Loss) Recognized in Income on Derivatives
		Three Months Ended March 31,

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Our calculation of the fair value of derivative instruments includes several assumptions. The fair value hierarchy prioritizes these input assumptions in the following three broad levels:

Level 1 – Valuation is based on quoted prices (unadjusted) in active markets for identical assets or liabilities we have the ability to access at the measurement date.

Level 2 – Valuation is based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and model based valuations for which all significant inputs are observable in the market.

Level 3 – Valuation is based on model based techniques that use unobservable inputs for the asset or liability. These inputs reflect our own assumption about the assumption market participants would use in pricing the asset or liability.

The following tables categorize our fair value instruments, measured on a recurring basis, according to the assumptions used to calculate those values:

				Fair Value Measurements Using
Description	Asset / (Liability) Balance at 3/31/2012			Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)

Interest rate swaps are valued using discounted cash flows. The key input used is the LIBOR swap rate, which is observable at commonly quoted intervals for the full term of the swap. Available-for-sale securities are valued using quoted market prices. Deferred compensation and supplemental pension plan assets are valued using quoted prices for similar assets in active markets.

Note 9:          NONCONTROLLING INTEREST

In January 2011, we acquired the remaining noncontrolling interest in Volclay South Africa (Proprietary) Limited, a part of our chromite business, for approximately $5.6.

In February 2011, we sold 26% of our interest in Batlhako Mining Limited (“Batlhako”) to Vengawave (Proprietary) Limited, which is a Black Economic Empowerment enterprise (a “BEE”) in the Republic of South Africa. Batlhako is our subsidiary dedicated strictly to mining chromite ore and selling it to one of our other subsidiaries for further processing and sale to the end customer. South African law requires that we have a BEE as a partner in our mining operations and this transaction was consummated to comply with those regulations.

The following table sets forth the effects of these transactions on equity attributable to AMCOL’s shareholders:

Note 10:          CONTINGENCIES

We are party to a number of lawsuits arising in the normal course of business. Since the mid-1980s, we and/or our subsidiaries have been named as one of a number of defendants in product liability lawsuits relating to the minor free-silica content of our bentonite products used in the metalcasting industry. The plaintiffs in these lawsuits are primarily employees of our foundry customers. Our oilfield services segment is also party to two lawsuits alleging damages caused by our coiled tubing operations in Louisiana; one lawsuit alleges damages of $28 and the other of $9. We do not believe that any pending litigation will have a material adverse effect on our consolidated financial statements.

Such forward-looking statements include statements relating to our Company or our operations that are preceded by terms such as “expects,” “believes,” “anticipates,” “intends” and similar expressions, and statements relating to anticipated growth and levels of capital expenditures. Such forward-looking statements are not guarantees of future performance and involve risks and uncertainties. Our actual results, performance or achievements could differ materially from the results, performance or achievements expressed in, or implied by, these forward-looking statements as a result of various factors, including without limitation the following: actual performance in our various markets; conditions in the metalcasting and construction markets; oil and gas prices and conditions in those industries; operating costs; seasonality of our environmental and oilfield services segments; competition and regulation; currency exchange rates and devaluations; delays in development, production and marketing of new products; integration of acquired businesses; conducting and expanding operations in international markets; and other factors set forth from time to time in our reports filed with the Securities and Exchange Commission (SEC). We undertake no duty to update any forward looking statements to actual results or changes in our expectations.

Overview

We are a global company focused on long term profitability growth through the development and application of minerals and technology products and services for use in various industrial and consumer markets. The majority of our revenue growth has been achieved by sustaining our products’ technological advantages, developing new products and applying them in innovative ways, bringing additional products and services to markets we already serve, and overall growth in the industries we serve. We focus our research and development activities in areas where we can either leverage our current customer relationships and mineral reserves or enhance existing or related products and services.

For our products that use minerals, the principal mineral that we utilize is bentonite. We own or lease bentonite reserves in the U.S., Australia, China and Turkey. Additionally, through our affiliates and joint ventures, we have access to bentonite reserves in Egypt, India, and Mexico. We also market and develop applications for other minerals, including chromite ore from our mine in South Africa.

Bentonite is surface mined when it is commercially feasible to have it shipped to a plant for further processing, including crushing, drying, milling, and packaging. Bentonite deposits have varying physical properties which require us to identify which markets our reserves can serve. Nicknamed the mineral of a thousand uses, bentonite’s unique characteristics include its ability to bind, swell, adsorb, control rheology, soften fabrics, and have its surface modified through chemical and physical reactions. Our research and development activities, including our understanding of bentonite properties, mining methods, processing and application to markets, are some of the core components of our longevity and future prospects.

18

We operate in five segments: minerals and materials, environmental, oilfield services, transportation and corporate. Both our minerals and materials and environmental segments operate manufacturing facilities in North America, Europe, and the Asia-Pacific region. Our minerals and materials segment also owns and operates a chromite mine in South Africa. Our oilfield services segment principally operates in the Gulf of Mexico and surrounding states and also has a growing presence in South America, Africa and Asia. Additionally, we have a transportation segment that performs trucking services for our domestic minerals and materials and environmental businesses as well as third parties.

Our customers are engaged in various end-markets and geographic regions. Customers in the minerals and materials segment range from foundries that produce castings for automotive, industrial, and transportation equipment, including heavy-duty trucks and railroad cars, to producers of consumer goods, including cat litter, cosmetics and laundry care. Customers in our environmental segment include construction contractors, engineering contractors and government agencies. The oilfield services segment’s customer base is primarily comprised of oil and natural gas service or exploration companies. A significant portion of our products have been used in the same applications for decades and have experienced minimal technological obsolescence. A majority of our sales are made pursuant to short-term agreements; therefore, terms of sale, such as pricing and volume, can change within our fiscal year.

A majority of our revenues are generated in the Americas, principally North America. Consequently, the state of the U.S. economy, and especially the metalcasting, industrial construction, and oil and gas exploration and production industries, impacts our revenues. Our fastest growing markets are in the Asia-Pacific and European regions.

Sustainable, long-term profitable growth is our primary objective. We employ a number of strategic initiatives to achieve this goal:

• Organic growth: The central component of our growth strategy is expansion of our product lines and market presence. We have a history of commitment to research and development activities directed at bringing innovative products to market. We believe this approach to growth offers the best probability of achieving our long-term goals at the lowest risk.

• Globalization: As we have done for decades, we continue to expand our manufacturing and marketing organizations into emerging geographic markets. We see significant opportunities in the Asia-Pacific and Eastern European regions for expanding our revenues and earnings over the long-term as a number of markets we serve, such as metalcasting and lining technologies, are expected to grow in these areas. We expect to take advantage of these growth areas, either through our wholly-owned subsidiaries or investments in affiliates and joint ventures.

• Mineral development: Bentonite is a component in a majority of the products we supply. Since it is a natural material, we must continually expand our reserve base to maintain a long-term business. Our goal is to add new reserves to replace the bentonite mined each year. Furthermore, we need to assure that new reserves meet the physical property requirements for our diverse product lines and are economical to mine. Our organization is committed to developing its global reserve base to meet these requirements.

19

• Acquisitions: We continually seek to acquire complementary businesses, as appropriate, when we believe those businesses are fairly valued and fit into our growth strategy.

A number of risks will challenge us in meeting these long-term objectives, and there can be no assurance that we will achieve success in implementing any one or more of them. We describe certain risks throughout this report as well as under “Item 1A. Risk Factors” and “Item 7A. Quantitative and Qualitative Disclosure About Market Risk” within our Annual Report on Form 10-K for the year ended December 31, 2011. In general, the significance of these risks has not materially changed since our Annual Report on Form 10-K for the period ended December 31, 2011.

Critical Accounting Policies and Estimates

Management’s Discussion and Analysis of our Financial Condition and Results of Operations describes relevant aspects of our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. We evaluate the accounting policies and estimates used to prepare the financial statements on an ongoing basis. We consider the accounting policies used in preparing our financial statements to be critical accounting policies when they are both important to the portrayal of our financial condition and results of operations, and require us to make estimates, complex judgments, and assumptions, including with respect to events which are inherently uncertain. As a result, actual results could differ from these estimates. For more information on our critical accounting policies, please read our Annual Report on Form 10-K for the year ended December 31, 2011.

Analysis of Results of Operations

Following is a discussion and analysis that describes certain factors that have affected, and may continue to affect, our financial position and operating results. This discussion should be read with the accompanying condensed consolidated financial statements.

The following consolidated income statement review and segment analysis discuss the results for the three months ended March 31, 2012 and the comparable results in the prior year. In each section, a discussion of our consolidated results is presented first, followed by a more detailed discussion of performance within our segments. We note that certain amounts reported in this Form 10-Q differ from those reported in our press release dated April 27, 2012 due to changes in our calculation of income tax expense in the quarter. Please see the discussion of income tax expense hereafter in this section of Analysis of Results of Operations for further details.

We measure sales fluctuations by the relevant components: organic, acquisitions, and foreign currency translation. Fluctuation due to foreign currency translation is measured as the change in revenues resulting from differences in currency exchange rates between periods. If applicable, fluctuation due to acquisitions is measured as the change in revenues resulting from acquired businesses within the first year (twelve consecutive months) we own them. Any remaining fluctuation is due to organic components. The following table details the consolidated sales fluctuations by components over the prior year’s comparable period:

	Organic		Acquisitions		Foreign   Exchange		Total
Minerals and materials		4.7%		0.0%		-0.3%		4.4%
Environmental		0.3%		0.0%		-0.6%		-0.3%
Oilfield services		4.9%		0.0%		0.0%		4.9%
Transportation & intersegment shipping		-0.7%		0.0%		0.0%		-0.7%
Total		9.2%		0.0%		-0.9%		8.3%
% of growth		111.0%		0.0%		-11.0%		100.0%

The following table shows the distribution of sales across our three principal geographic regions (Americas; Europe, Middle East, and Africa (EMEA); and Asia Pacific) and the comparable total from the prior year’s period:

	Americas		EMEA		Asia Pacific		Total
Minerals and materials		32.8%		8.8%		11.0%		52.6%
Environmental		11.8%		7.9%		1.8%		21.5%
Oilfield services		20.2%		1.1%		2.1%		23.4%
Transportation & intersegment shipping		2.5%		0.0%		0.0%		2.5%
Total - current year’s period		67.3%		17.8%		14.9%		100.0%
Total from prior year’s comparable period		64.2%		22.5%		13.3%		100.0%

Net sales:

Our net sales grew organically and were negatively affected by foreign currency translation. The majority of the increase occurred in our minerals and materials and oilfield services segments. Sales were less concentrated in our EMEA region due to decreased sales in our environmental segment, especially within Western Europe , partially due to our decision to exit the contracting services business in Ireland. Also affecting our EMEA sales was our chromite sales in South Africa, which decreased due to a temporary plant shut down as we commission new production equipment there.

Gross profit:

Overall gross profit increased due to the increase in sales mentioned above. Gross margin increased 110 basis points due to a 260 basis point increase in our minerals and materials segment’s gross margin.

22

Selling, general and administrative expenses (SG&A):

SG&A expenses increased $4.5 million. This includes a $1.3 million bad debt expense within our oilfield services segment as well as $0.7 million of expenses incurred to write off certain information technology equipment in our corporate segment. The remaining increase relates to increased benefits and compensation expenses, such as commissions, which generally increase with sales.

Operating profit:

Operating profit increased due to the increase in gross profit mentioned earlier, partially offset by the increase in SG&A expenses. Overall, however, operating profits increased faster than sales, reflective of our increased operating leverage.

Other income (expense), net:

The increase in Other, net relates to a $1.8 million provision for estimated losses on certain non-operating assets.

Income tax expense:

Our effective tax rate for the current quarter was 28.7% versus 27.7% in the prior year’s quarter. Our income tax expense and effective tax rate fluctuated between the periods presented due to discrete items recorded and the distribution of income between taxing jurisdictions. The current year’s quarter does not include any discrete items whereas the prior year’s quarter includes $0.6 million of discrete tax expense. In addition, the current quarter’s income is more heavily concentrated in our domestic businesses which typically have a higher income tax rate than our foreign operations.

The income tax expense in our press release dated April 27, 2012 included discrete income tax benefits of $0.6 million which, subsequent to the press release, we determined were incorrectly calculated. As a result, we have eliminated these benefits and increased income tax expense by the same amount. This had the effect of increasing our effective tax rate by 360 basis points and decreasing our diluted earnings per share by $0.02 per share in this quarter.

Diluted earnings per share from continuing operations:

Diluted earnings per share from continuing operations increased in the quarter due to increased net income from continuing operations.

Quarterly Review of Each Segment’s Results

Following is a review of operating results for each of our five reporting segments:

Minerals and Materials Segment

Minerals and Materials	Three Months Ended March 31,
	2012				2011				2012 vs. 2011
	(Dollars in millions)
Net sales	$	125.5	100.0	%	$	115.9	100.0	%	$	9.6	8.3	%
Cost of sales		91.9	73.2	%		87.8	75.8	%
Gross profit		33.6	26.8	%		28.1	24.2	%		5.5	19.6	%
Selling, general and administrative expenses		12.0	9.6	%		12.0	10.4	%		-	0.0	%
Operating profit		21.6	17.2	%		16.1	13.8	%		5.5	34.2	%

23

Minerals and Materials Product Line Sales	Three Months Ended March 31,
	2012		2011		% change
	(Dollars in Millions)
Metalcasting	$	62.9	$	55.3		13.7	%
Specialty materials		26.8		27.4		-2.2	%
Basic minerals		19.5		16.4		18.9	%
Pet products		14.4		15.1		-4.6	%
Other product lines		1.9		1.7		11.8	%
Total		125.5		115.9		8.3	%

Increased selling prices accounted for 75% of the increase in sales. We have been successful in increasing selling prices in our metalcasting product line and in our petroleum products (included within our basic minerals product line). Our metalcasting product line, which includes chromite sales to foundry customers, continues to experience an increase in demand due to growth in demand for automobile and heavy equipment castings. Our petroleum products are also in high demand given the increased drilling activity occurring in the United States.

The aforementioned selling price increases are the major contributor to the increase in both gross profits and gross margins. However, they were partially offset by overall increases in costs, especially with regards to certain raw materials. On a combined basis, the increased selling prices and costs account for 89% of the increase in gross profits.

The trends in operating profit follow those of gross profit. Operating margins, however, increased more than gross margins (340 basis points versus 260 basis points) due to the fact that the majority of the increase in sales (increased selling prices) were not accompanied by increased SG&A costs.

Environmental Segment

Environmental	Three Months Ended March 31,
	2012			2011			2012 vs. 2011
	(Dollars in Millions)
Net sales	$	51.1	100.0%	$	51.7	100.0%	$	(0.6	)	-1.2%
Cost of sales		36.2	70.8%		35.7	69.1%
Gross profit		14.9	29.2%		16.0	30.9%		(1.1	)	-6.9%
Selling, general and administrative expenses		14.0	27.4%		13.6	26.3%		0.4		2.9%
Operating profit (loss)		0.9	1.8%		2.4	4.6%		(1.5	)	-62.5%

Environmental Product Line Sales	Three Months Ended March  31,
	2012		2011		% change
	(Dollars in Millions)
Lining technologies	$	19.3	$	21.6		-10.6	%
Building materials		18.8		17.5		7.4	%
Drilling products		8.6		6.0		43.3	%
Contracting services		4.4		6.6		-33.3	%
Total		51.1		51.7		-1.2	%

24

Sales decreased slightly in the current quarter as decreases in our lining technologies and contracting services product lines overshadowed increases in our drilling and building materials product lines. Demand for lining technology product and systems has decreased in the US and Europe, and we are in the process of exiting some portions of the contracting services business in Europe. We have enjoyed continued success from new product launches within our building materials group, and demand for our drilling product lines remains strong.

Gross profit decreased as lower volumes caused per unit production costs to increase. In addition, we experienced low margins on some contracting services jobs in Europe. Sales were also slightly more concentrated in lower margin, accessory products.

SG&A expenses increased for a variety of reasons, none of which are individually significant. The increases relate to increased commissions on building materials product line sales, professional fees, investments being made in India (a new market for us), and expenses associated with restructuring this segment.

The trends in operating profit and operating profit margin follow those of gross profit and gross margin combined with the increased SG&A levels.

Oilfield Services Segment

Oilfield Services	Three Months Ended March 31,
	2012			2011			2012 vs. 2011
	(Dollars in Millions)
Net sales	$	55.3	100.0%	$	44.7	100.0%	$	10.6		23.7%
Cost of sales		39.9	72.2%		32.0	71.6%
Gross profit		15.4	27.8%		12.7	28.4%		2.7		21.3%
Selling, general and administrative expenses		10.6	19.2%		7.8	17.4%		2.8		35.9%
Operating profit		4.8	8.6%		4.9	11.0%		(0.1	)	-2.0%

The majority of the revenue increase (approximately 62%) occurred in our foreign operations, which primarily focus on water treatment technologies. In our foreign markets, we have been successful in gaining new contracts with customers, leading to the increase. Domestically, revenues increased mostly in our coil tubing and water treatment service lines due to increases in overall demand and increased service capacity after having purchased additional equipment in late 2011.

Gross profits increased with sales and gross margins remained relatively stable overall. However, gross profit margins on domestic operations decreased due to increased costs in our coil tubing services that resulted from the commissioning of new equipment and an increased concentration of land based jobs. Gross profit margins in our international operations benefitted from increased economies of scale given the growth in revenues.

Of the $2.8 million increase in SG&A expenses, approximately $1.3 million of which relates to one bad debt. The remainder of it relates to increased compensation and benefit expenses associated with improved performance and growth within the segment.

25

Transportation Segment

Transportation	Three Months Ended March 31,
	2012			2011			2012 vs. 2011
	(Dollars in Millions)
Net sales	$	11.1	100.0%	$	12.7	100.0%	$	(1.6	)	-12.6%
Cost of sales		9.9	89.2%		11.3	89.0%
Gross profit		1.2	10.8%		1.4	11.0%		(0.2	)	-14.3%
Selling, general and administrative expenses		1.0	9.0%		0.9	7.1%		0.1		11.1%
Operating profit		0.2	1.8%		0.5	3.9%		(0.3	)	-60.0%

This segment provides services to third parties as well as AMCOL companies within our other segments. Revenues decreased due to increased competition as well as availability of drivers, who are being recruited to oil and gas opportunities in the Bakken shale region. Operating profits decreased as a result of the decrease in revenues.

Corporate Segment

Corporate	Three Months Ended March 31,
	2012			2011			2012 vs. 2011
	(Dollars in Millions)
Intersegment sales	$	(7.2	)	$	(7.2	)		-
Intersegment cost of sales		(7.2	)		(6.7	)
Gross profit (loss)		-			(0.5	)		0.5
Selling, general and administrative expenses		6.0			4.8			1.2		25.0%
Operating loss		(6.0	)		(5.3	)		(0.7	)	13.2%

Intersegment sales are eliminated in our corporate segment. These are mostly sales between our transportation segment and our minerals and materials and environmental segments as well as sales between our minerals and materials segment to our environmental and oilfield services segments.

Corporate SG&A expenses increased due to $0.7 of expenses incurred to write-off certain information technology investments and increased professional fees.

Balance Sheet Review

Our working capital level remained steady; it was $293.7 million at March 31, 2012 and $294.2 million at December 31, 2011. We were able to maintain a stable working capital level even though sales increased significantly due to improvements in collections of accounts receivable. We also increased our investments in property, plant and equipment, mostly in our oilfield services and minerals and materials segments, to help grow and maintain those businesses. Improved performance of working capital allowed us to not only fund these investments but also reduce our debt balance in the first three months of 2012.

26

Our accumulated other comprehensive income increased $10.2 million, primarily due to the revaluation of the net assets of our foreign subsidiaries into our reporting currency, USD, during consolidation. Although all foreign subsidiaries are subject to translation adjustments during consolidation, the exchange rates between the USD and the PLN, the ZAR and the TRY have fluctuated significantly, causing the majority of the change in this account. Last, our treasury stock account has decreased due to exercise of stock compensation awards by our employees. We expect to exhaust our supply of treasury shares during 2012 as we provide them to employees upon exercise of stock compensation awards; if our supply is exhausted, we may issue additional shares as awards are exercised.

Liquidity and Capital Resources

Cash flows from operations, an ability to issue new debt instruments, an ability to lease equipment, and borrowings from our revolving credit facility have historically been our sources of funds to provide working capital, make capital expenditures, acquire businesses, repurchase common stock, and pay dividends to shareholders. We believe cash flows from operations and borrowings from our unused and committed credit facility will be adequate to support our current business needs for the foreseeable future.

We may need additional debt or equity facilities in order to pursue acquisitions, when and if these opportunities become available, and we may or may not be able to obtain such facilities on terms substantially similar to our current facilities as discussed in Item 1A – Risk Factors of our Annual Report on Form 10-K filed for 2011. Terms of any new facilities, especially interest rates or covenants, may be significantly different from those we currently have.

Following is a discussion and analysis of our cash flow activities as presented in the Condensed Consolidated Statement of Cash Flows presented within Part 1, Item 1 of this report.

Cash Flows ($ in millions)	Three Months Ended March  31,
	2012			2011

Cash flows from operating activities increased from the prior year period largely due to improved management of our working capital, especially accounts receivable.

Capital expenditures for the first three months of 2012 and 2011 were $16.6 million and $10.4 million, respectively. In these periods, the expenditures include $4.1 million and $0.7 million, respectively, of expenditures associated with establishing our South African chromite operations. In the three months ended March 31, 2012, the majority of our capital expenditures occurred in our oilfield services segment (to increase the size of our equipment fleet) and our minerals and materials segment (mostly for maintenance capital to ensure stability as the business experiences growth). We expect our capital expenditures in our fiscal year for 2012 to exceed the levels experienced in recent years.

Financial Position ($ in millions)	As at
	March 31, 2012		December 31, 2011
Non-cash working capital	$	276.8	$	270.5
Goodwill & intangible assets		107.1		106.1
Total assets		850.1		842.7
Long-term debt		250.7		260.7
Other long-term obligations		65.1		63.7
Total equity		422.8		400.2

Non-cash working capital at March 31, 2012 increased $6.3 million as compared to the amount at December 31, 2011 due to increased working capital required to support the growth in the business. Given the seasonality of our environmental and oilfield services segments as well as the project nature of some of our services provided in the oilfield services segment, working capital levels have historically increased in the early and middle parts of the year and then decreased later in the year; we do not see a reason why this trend would not continue.

Improved performance of working capital allowed us to reduce long-term debt by $10.0 million in the first quarter of 2012. Long-term debt as a percentage of total capitalization decreased 220 basis points to 37.2%. We have approximately $179.2 million of borrowing capacity available from our revolving credit facility as of March 31, 2012. We are in compliance with the financial covenants related to the revolving credit facility as of the period covered by this report.

We are party to a number of lawsuits arising in the normal course of business. Since the mid-1980s, we and/or our subsidiaries have been named as one of a number of defendants in product liability lawsuits relating to the minor free-silica content of our bentonite products used in the metalcasting industry. The plaintiffs in these lawsuits are primarily employees of our foundry customers. Our oilfield services segment is also party to two lawsuits alleging damages caused by our coiled tubing operations in Louisiana; one lawsuit alleges damages of $28 million and the other of $9 million. We do not believe that any pending litigation will have a material adverse effect on our consolidated financial statements.

Contractual Obligations and Off-Balance Sheet Arrangements

Item 7 of our Annual Report on Form 10-K, for the year ended December 31, 2011 discloses our contractual obligations and off-balance sheet arrangements. There were no material changes in our contractual obligations and off-balance sheet arrangements.

Item 3: Quantitative and Qualitative Disclosures About Market Risk

There were no material changes in our market risk from the disclosures made in our Annual Report on Form 10-K for the year ended December 31, 2011 other than those discussed in Part 1, Item 2 of this report.

Item 4: Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Based on that evaluation, they concluded that, as of the end of such period, our disclosure controls and procedures were effective in recording, processing, summarizing, and reporting, on a timely basis, information we are required to disclose in the reports we file or submit under the Exchange Act.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Exhibit 10.2

CETCO OILFIELD SERVICES COMPANY

2012 PERFORMANCE AGREEMENT

This Performance Agreement (the “Agreement”) is entered into as of March 14, 2012 by and between CETCO Oilfield Services Company, a Delaware corporation (the “Company”), and Michael R. Johnson (“Employee”).

WHEREAS, Employee has served and continues to serve as a key employee of the Company;

WHEREAS, the Company and Employee are parties to a 2010 Performance Agreement (the “2010 Agreement”) and

WHEREAS, the Company desires to reward Employee for his services to the Company and to encourage him to continue to work for the benefit of the Company.

NOW, THEREFORE, in consideration of the premises and the mutual covenants and obligations herein after set forth, the Company and the employee agree as follows:

1. Definitions. The following terms used in this Agreement are defined as follows:

“Increase In Operating Profit” means the increase in Operating Profit for each of the years ending December 31, 2012, 2013, 2014 and 2015 over the greater of (i) the 2011 Operating Profit ($19,881,000) and (ii) Operating Profit of any prior fiscal year (following 2011).

The following guidelines apply to this calculation:

(i) in the event there is a decrease in a current year (Year X) from the 2011 Operating Profit or the Operating Profit in any prior fiscal year (following 2011), no offset or deduction will be made for purposes of calculating Increase In Operating Profit and the determination as to whether there is any increase in Operating Profit in the following year (Year Y) will be made by comparing the Operating Profit of Year Y to the greater of (i) the 2011 Operating Profit and (ii) the Operating Profit of any prior year (following 2011) Operating Profit;

(ii) in order to calculate the Increase in Operating Profit following an acquisition, the following shall apply:

a. with respect to the year of an acquisition, any earnings or losses attributable to the acquired business will be included in the calculation of Operating Profit commencing as of closing, and a pro rata amount (based on the period from closing to fiscal year end) of historical earnings or losses of the acquired business in the prior fiscal year will be included in the calculation of the prior year Operating Profit amount for purposes of comparison. For example, if an acquisition closes on June 30, 2012, (i) any Operating Profit attributable to the acquired business for the period between July 1 and December 31, 2012 will be included in the calculation of 2012 Operating Profit and (ii) the earnings or losses of the acquired business for the period from July 1 thru December 31, 2011 will be added to the calculation of 2011 Operating Profit for purposes of comparison to 2012 Operating Profit; and

b. with respect to the year following an acquisition, a pro rata amount of earnings or losses attributable to the acquired business in the period prior to closing in the year of the acquisition will be included in the calculation of Operating Profit for the year of the acquisition for purposes of comparison. For example, if an acquisition closes on June 30, 2012, the Operating Profit of the earnings or losses of the acquired business for the period January 1 thru June 30, 2010 will be added to the calculation of 2011 Average Operating Profit for purposes of comparison to 2012 Operating Profit.

The determination of the prior period net income of any acquired business will be based on the financial information used for acquisition justification, and is also subject to adjustment in the Company’s reasonable discretion for acquisition expenses, such as closing bonuses.

c. for purposes of calculating Operating Profit in an acquired business, the expenses related to (i) intangible assets acquired by the Company and (ii) the “step-up” in basis of property, plant and equipment acquired by the Company shall be excluded in any such calculation of Operating Profit.

“AMCOL” means the Company’s parent company, AMCOL International Corporation, a Delaware corporation.

“Business” means the sale, marketing, and operation of businesses included in the oilfield services segment of AMCOL.

“Code” means the Internal Revenue Code of 1986 and the regulations thereunder.

“Employee Participation Share” means the percent of the Long Term Incentive Pool allocated to Employee in Section 2 of the Agreement subject to the other provisions of this Agreement, including Section 3.

“Long Term Incentive Pool” means an amount of between 15%-25% of the Increase in Operating Profit determined for each of 2012, 2013, 2014 and 2015 in accordance with the provisions of Exhibit A and accrued annually. The amounts accrued for each year shall be aggregated following the determination of the amount for 2015.

“Oilfield Services Segment” means the AMCOL subsidiaries and/or business units engaged worldwide in the Business including, without limitation, oilfield filtration services, well testing services, industrial wastewater treatment, coiled tubing services, nitrogen services, and oilfield equipment rental.

“Operating Profit” for any specified period means the consolidated net sales of the Oilfield Services Segment less the applicable operating expenses, determined in accordance with Generally Accepted Accounting Principles and consistent with the Company’s and AMCOL’s past practice. In determining Operating Profit, the following shall be included: (i) the costs of AMCOL corporate allocations and bonus accruals (including without limitation accrual for any long term incentive plan or agreement such as this agreement); (ii) any provision for depreciation or amortization; (iii) from and after the closing date, any earnings or losses attributable to businesses included within the Oilfield Services Segment purchased or established after the date of this Agreement; (iv) workmen’s compensation claims, costs, expenses and premiums; and (v) any gains or loss on the sale, conversation or other disposition of

2

any fixed assets or intangible assets, and the following shall be excluded: (x) any federal, state or local income taxes; and (y) any other transactions reported as extraordinary gains or extraordinary losses in accordance with Generally Accepted Accounting Principles.

“Return on Capital Employed” means the consolidated ROCE of the Oilfield Services Segment less the applicable operating expenses, determined in accordance with Generally Accepted Accounting Principles and consistent with the Company’s and AMCOL’s past practice.

155. Employee Participation Share. The Company hereby grants to Employee    % of the Long Term Incentive Pool. This award is made pursuant to AMCOL’s 2012 Cash Incentive Plan and is subject to all of the terms and conditions of this Plan, including Section 9 (Clawback). Subject to the provisions of Section 3 below and the eligibility requirements set forth below, on February 15, 2016 the Company will pay to Employee an amount equal to his Employee Participation Share. Employee is only eligible to receive this cash payment if he is a full-time employee of the Company or one of its affiliates in good standing on February 15, 2016. Except as otherwise provided herein, the Employee will not be entitled to any pro rata share of the Employee Participation Share payment if his employment terminates for any reason prior to February 15, 2016. Other than the potential cash payment provided for under this Section 2, the Employee Participation Share does not entitle Employee to any other rights with respect to AMCOL, the Company or the Oilfield Services Segment. The parties agree that notwithstanding any other provision in the Agreement to the contrary, that to the extent that the ROCE of the Oilfield Services Segment is less than or equal to                     percent (    %) for 2012,                    (     %) for 2013,                     (    %) for 2014 and                     percent (    %) 2015 for any year the increase in Operating Profit for that year will not be included in the Cash Bonus Calculation. A sample calculation is set forth on Exhibit A hereto.

156. Adjustment of Amounts Payable. Any and all amounts payable to Employee hereunder shall be reduced dollar-for-dollar for any amounts paid to Employee pursuant to the 2010 Agreement. The Company may, in its sole and absolute discretion, select additional employees to receive an Employee Participation Share. In such case, the Employee Participation Share allocated to Employee and the amounts payable to Employee under Section 2 of this Agreement may be reduced proportionately. In the event any employee entitled to receive an Employee Participation Share becomes ineligible to receive such payment, other participating employees will not automatically receive a pro rata share of such employee’s possible payments. Instead, the Company will, in its sole and absolute discretion, determine whether, and if so, how, to distribute such employee’s Employee Participation Share to other Company employees; provided, however, that no distribution will be made if doing so would cause any of the payments under this Agreement not to be “performance-based compensation” under Code Section 162(m).

157. Employment-At-Will. The execution and delivery of this Agreement does not in any way guarantee continued employment with the Company or any of its affiliates. Employee is an employee-at-will and his employment may be terminated by the Company, in its sole and absolute discretion, at any time, for any reason, with or without notice. Except as otherwise provided herein, the Employee will not be entitled to any pro rata share of the Employee Participation Share if his employment terminates for any reason prior to the payment date.

3

5. Termination of Employment.

(A) In the event of the Employee’s “separation from service” within the meaning of Code Section 409A due to death or permanent disability (as defined pursuant to the Company’s benefit plans), the employee or his estate shall be entitled to receive a share of the Employee Participation Shares based on the Increase In Operating Profits, if any, for all completed fiscal years and fiscal quarters preceding the date of Employee’s separation from service.

(B) In the event the Employee’s employment terminates for any other reason prior to the payment dates hereunder, either by the Company or by Employee, Employee will not be eligible to receive the Employee Participation Share or any pro rata share thereof.

6. Payments Cumulative Any payments made under this Agreement will be in addition to any other compensation or bonuses otherwise paid by the Company to Employee.

7. Withholding The Company may withhold from any payment that it is required to make under this Agreement amounts sufficient to satisfy applicable withholding requirements under any federal, state or local law.

8. Change of Control If the Oilfield Services Segment is sold to a third party (excluding members of management of the Oilfield Services Segment) in a transaction that constitutes a “change of control” event within the meaning of Code Section 409A with respect to the segment, Employee shall be entitled a share of the Employee Participation Share based on the Increase In Operating Profit, if any, as of the date of closing.

9. Non-Compete In consideration for the execution and delivery of this Agreement and other good and valuable consideration, Employee agrees to execute, or re-execute, as the case may be, a confidentiality agreement/covenant not to compete, the form of which is set forth in Exhibit B, in favor of the Company simultaneously with the execution of this Agreement.

10. Records: Records for determination of bonuses payable under this Agreement will be maintained in accordance with generally accepted accounting principles and in accordance with past practice of the Company.

11. Binding Effect; Assignment. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties’ successors and permitted assigns. This Agreement and the rights and obligations of the parties hereunder may not otherwise be assigned or delegated by either party without the prior written consent of the other party hereto.

12. Entire Agreement. This Agreement constitutes the entire agreement between the parties concerning the subject matter hereof and supersedes any and all prior and contemporaneous agreements, written or oral, between the parties relating to the subject matter hereof.

13. Amendment. Subject to the provisions of Section 3 above, no amendment or modification of the terms of this Agreement shall be binding upon either party unless reduced to writing and signed by Employee and a duly appointed officer of the Company.

4

14. Severability. In the event that any provision or portion of this Agreement shall be determined to be invalid or unenforceable for any reason, the remaining provisions and portions of this Agreement shall be unaffected thereby and shall remain in full force and effect to the fullest extent permitted by law.

15. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed the original without, but all of which together shall constitute one and the same instrument.

16. Headings. Headings of the sections and subsections of this Agreement are inserted for convenience of reference only and shall not constitute a part hereof.

17. Governing Law. This Agreement and the rights and obligations of the parties hereunder shall be governed, construed and enforced in accordance with the internal laws of the State of Delaware, excluding any choice of law rules which may direct the application of the laws of another jurisdiction.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the day and year first above written.

Exhibit 95.1

Mine Safety Disclosures

We have in place health and safety programs that include extensive employee training, accident prevention, workplace inspection, emergency response, accident investigation, regulatory compliance and program auditing. The objectives of our health and safety programs are to eliminate workplace incidents, comply with all mining-related regulations and improve mine safety.

The operation of our domestic mines is subject to regulation by the federal Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”). MSHA inspects our mines on a regular basis and issues various citations and orders when it believes a violation has occurred under the Mine Act. As required by the reporting requirements included in section 1503(a) of the Dodd-Frank Act, we present the following information regarding mining safety and health matters, with respect to our mining operations.

For the three-month period ended March 31, 2012, none of our mining operations received written notice from MSHA of (i) an order issued under section 104(b) of the Mine Act; (iii) a citation or order for unwarrantable failure to comply with mandatory health or safety standards under section 104 (d) of the Mine Act; (iv) a flagrant violation under section 110(b)(2) of the Mine Act; (v) an imminent danger order under section 107(a) of the Mine Act; (vi) a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of our mine health or safety hazards under section 104(e) of the Mine Act; or (vii) the potential to have such a pattern. For the three-month period ended March 31, 2012, we experienced no fatalities.

The table below sets forth by mining complex the total number of citations and/or orders issued during the three-month period ended March 31, 2012 by MSHA to AMCOL and its subsidiaries under the indicated provisions of the Mine Act, together with the total dollar value of proposed MSHA assessments.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Note 1:           SUMMARY OF SIGNIFICANT ACCOUNTING POLICIE

Company Operations

We, AMCOL International Corporation (the "Company"), are a global company focused on long-term profitability growth through the development and application of minerals and technology products and services for use in various industrial and consumer markets. We operate in five segments: minerals and materials, environmental, oilfield services, transportation and corporate.

Our minerals and materials segment mines, processes and distributes minerals and products for use in various industrial and consumer markets, including metalcasting, pet care, laundry care, and drilling industries. Additionally, this segment develops and manufactures synthetic materials principally for personal care applications.

Our environmental segment manufactures and distributes products for use as moisture and vapor barriers in commercial construction, landfills and a variety of other industrial and commercial applications and provides related services.

Our oilfield services segment provides both onshore and offshore water treatment filtration, well testing, pipeline separation, nitrogen, coil tubing and other services to the oil and natural gas industry.

Our transportation segment includes both a long-haul trucking business and a freight brokerage business serving our domestic subsidiaries as well as third parties.

Our corporate segment includes the elimination of intersegment sales as well as certain expenses associated with research and development, management, employee benefits and information technology activities for our Company. Approximately 71% and 82% of the revenue elimination in the three months ended March 31, 2012 and 2011, respectively, represents elimination of shipping revenues between our transportation segment and its domestic sister companies.

The composition of our revenues by segment is as follows:

	Three Months Ended March 31,
	2012	2011
Minerals and materials	53%	53%
Environmental	22%	24%
Oilfield services	23%	21%
Transportation	5%	6%
Intersegment sales	-3%	-4%
	100%	100%

Further discussion of our segment information is included in Note 4, "Business Segment Information."

Basis of Presentation

The financial information included herein has been prepared by management, and other than the condensed consolidated balance sheet as of December 31, 2011, is unaudited. The condensed consolidated balance sheet as of December 31, 2011 has been derived from, but does not include all of the disclosures contained in, the audited consolidated financial statements for the year ended December 31, 2011. The information furnished herein includes all adjustments that are, in our opinion, necessary for a fair presentation of our results of operations and cash flows for the interim periods ended March 31, 2012 and 2011, and our financial position as of March 31, 2012, and all such adjustments are of a normal and recurring nature. The accompanying condensed consolidated financial information should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2011.

Certain items in the prior year's condensed consolidated financial statements contained herein and notes thereto have been reclassified to conform to the condensed consolidated financial statement presentation for the three months ended March 31, 2012. These reclassifications did not have a material impact on our financial statements.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("US GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year for a variety of reasons, including the seasonality of both our environmental segment, which varies due to the seasonal nature of the construction industry, and our oilfield services segment, which varies due to seasonal weather patterns in its various geographic markets.

The condensed consolidated balance sheet as of December 31, 2011 has been derived from, but does not include all of the disclosures contained in, the audited consolidated financial statements for the year ended December 31, 2011. The information furnished herein includes all adjustments that are, in our opinion, necessary for a fair presentation of our results of operations and cash flows for the interim periods ended March 31, 2012 and 2011, and our financial position as of March 31, 2012, and all such adjustments are of a normal and recurring nature. The accompanying condensed consolidated financial information should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2011.

Certain items in the prior year's condensed consolidated financial statements contained herein and notes thereto have been reclassified to conform to the condensed consolidated financial statement presentation for the three months ended March 31, 2012. These reclassifications did not have a material impact on our financial statements.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("US GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.

The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year for a variety of reasons, including the seasonality of both our environmental segment, which varies due to the seasonal nature of the construction industry, and our oilfield services segment, which varies due to seasonal weather patterns in its various geographic markets.

INCOME TAXES

Note 6:          INCOME TAXES

Our effective tax rate for the three months ended March 31, 2012 and 2011 was 28.7% and 27.7%, respectively. For both periods, the rate differs from the U.S. federal statutory rate of 35.0% largely due to depletion deductions, changes in tax reserves in 2011, and differences in local tax rates on the income from our foreign subsidiaries.

In the normal course of business, we are subject to examination by taxing authorities throughout the world. With few exceptions, we are no longer subject to income tax examinations by tax authorities for years prior to 2004. In general, the United States Internal Revenue Service ("IRS") has examined our federal income tax returns for all years through 2009.

NONCONTROLLING INTEREST

Note 9:          NONCONTROLLING INTEREST

In January 2011, we acquired the remaining noncontrolling interest in Volclay South Africa (Proprietary) Limited, a part of our chromite business, for approximately $5.6.

In February 2011, we sold 26% of our interest in Batlhako Mining Limited ("Batlhako") to Vengawave (Proprietary) Limited, which is a Black Economic Empowerment enterprise (a "BEE") in the Republic of South Africa. Batlhako is our subsidiary dedicated strictly to mining chromite ore and selling it to one of our other subsidiaries for further processing and sale to the end customer. South African law requires that we have a BEE as a partner in our mining operations and this transaction was consummated to comply with those regulations.

The following table sets forth the effects of these transactions on equity attributable to AMCOL's shareholders:

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Note 7:          DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

As a multinational corporation with operations throughout the world, we are subject to certain market risks. We use a variety of practices to manage these market risks, including, when considered appropriate, derivative financial instruments. We use derivative financial instruments only for risk management and not for trading or speculative purposes.

The following table sets forth the fair values of our derivative instruments and where they are recorded within our condensed consolidated balance sheet:

Liability Derivatives	Balance Sheet Location	Fair Value as of
		March 31, 2012			December 31, 2011
Derivatives designated as hedging instruments:
Interest rate swaps	Other long-term liabilities	$	(8.7	)	$	(9.0	)

	Three Months Ended March 31,
	2012		2011
Interest rate swaps, net of tax	$	0.2	$	0.5

We use interest rate swaps to manage floating interest rate risk on debt securities. Interest rate differentials are paid or received on these arrangements over the life of the swap. As of March 31, 2012 and 2011, we had interest rate swaps outstanding which effectively hedge the variable interest rate on

$30.0 of our senior notes to a fixed rate of 5.6% per annum and $33.0 of our borrowings under our revolving credit agreement to a fixed rate of 3.3% per annum, plus credit spread.

Other

We are exposed to potential gains or losses from foreign currency fluctuations affecting net investments and earnings denominated in foreign currencies. We are particularly sensitive to currency exchange rate fluctuations between the following currency pairs: a) the Euro to the British pound (GBP) and the Polish Zloty (PLN), b) the South African Rand (ZAR) to the USD and the Australian dollar (AUD), c) the GBP to the Danish kroner (DKK) and the Swiss franc (SEK), and d) the USD to the Indian rupee (INR), the Thai baht (THB), and the Turkish lira (TRY). When considered appropriate, we enter into foreign exchange derivative contracts to mitigate the risk of fluctuations on these exposures.

We have not designated our foreign currency derivative contracts for hedge accounting treatment and therefore, changes in fair value of these contracts are recorded in earnings as follows:

Derivatives Not Designated as Hedging Instruments	Location of  Gain or (Loss) Recognized in Income on Derivatives	Amount of Gain or (Loss) Recognized in Income on Derivatives
		Three Months Ended March 31,

Fair Value Measurements

Fair Value Measurements [Abstract]

FAIR VALUE MEASUREMENTS

Note 8:           FAIR VALUE MEASUREMENTS

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Our calculation of the fair value of derivative instruments includes several assumptions. The fair value hierarchy prioritizes these input assumptions in the following three broad levels:

Level 1 – Valuation is based on quoted prices (unadjusted) in active markets for identical assets or liabilities we have the ability to access at the measurement date.

Level 2 – Valuation is based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and model based valuations for which all significant inputs are observable in the market.

Level 3 – Valuation is based on model based techniques that use unobservable inputs for the asset or liability. These inputs reflect our own assumption about the assumption market participants would use in pricing the asset or liability.

The following tables categorize our fair value instruments, measured on a recurring basis, according to the assumptions used to calculate those values:

				Fair Value Measurements Using
Description	Asset / (Liability) Balance at 3/31/2012			Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)
Interest rate swaps	$	(8.7	)	$	-	$	(8.7	)	$	-
Available-for-sale securities		2.9			2.9		-			-
Deferred compensation plan assets		9.0			-		9.0			-
Supplementary pension plan assets		8.1			-		8.1			-

				Fair Value Measurements Using
Description	Asset / (Liability) Balance at 12/31/2011			Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)
Interest rate swaps	$	(9.0	)	$	-	$	(9.0	)	$	-
Available-for-sale securities		3.8			3.8		-			-
Deferred compensation plan assets		8.0			-		8.0			-
Supplementary pension plan assets		7.6			-		7.6			-

Interest rate swaps are valued using discounted cash flows. The key input used is the LIBOR swap rate, which is observable at commonly quoted intervals for the full term of the swap. Available-for-sale securities are valued using quoted market prices. Deferred compensation and supplemental pension plan assets are valued using quoted prices for similar assets in active markets.

CONTINGENCIES

Note 10:          CONTINGENCIES

We are party to a number of lawsuits arising in the normal course of business. Since the mid-1980s, we and/or our subsidiaries have been named as one of a number of defendants in product liability lawsuits relating to the minor free-silica content of our bentonite products used in the metalcasting industry. The plaintiffs in these lawsuits are primarily employees of our foundry customers. Our oilfield services segment is also party to two lawsuits alleging damages caused by our coiled tubing operations in Louisiana; one lawsuit alleges damages of $28 and the other of $9. We do not believe that any pending litigation will have a material adverse effect on our consolidated financial statements.

Business Segment Information [Abstract]

BUSINESS SEGMENT INFORMATION

Note 4:          BUSINESS SEGMENT INFORMATION

As previously mentioned, we operate in five segments. We determine our operating segments based on the discrete financial information that is regularly evaluated by our chief operating decision maker, our President and Chief Executive Officer, in deciding how to allocate resources and in assessing performance. Intersegment sales are not material and are eliminated in the corporate segment. Our reportable measure of profit or loss for each segment is operating profit, which is defined as net sales less cost of sales and selling, general and administrative expenses related to a segment's operations. The costs deducted to arrive at operating profit do not include several items, such as net interest expense or income taxes. Segment assets are those assets used in the operations of that segment. Corporate assets include assets used in the operation of this segment as well as those used by or shared amongst our segments, including certain cash and equivalent assets, certain fixed assets, assets associated with certain employee benefit plans, and other miscellaneous assets.

The following tables set forth certain financial information by segment:
