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 5, “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/A for the year ended December 31, 2011.

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: CORRECTION OF ERRORS IN PREVIOUSLY REPORTED FINANCIAL STATEMENTS

We have corrected our previously issued financial statements for all periods prior to and including the twelve months ended December 31, 2011, in addition to the three months ended March 31, 2012 .  For the three months ended March 31, 2012, these errors increased net income available to AMCOL shareholders by $0.6.  Although there were several errors across various categories, we have summarized the errors and quantified the amount by which they increased (decreased) net income available to AMCOL shareholders into the following categories:

· Spain - $0.3 decrease for errors associated with accounting for inventory and other items in our environmental segment’s Spanish operations;

· South Africa – adjustments to correct errors related to the accounting for the acquisition of mineral rights in our minerals and materials segment’s chromite operations in South Africa;

· Poland – $0.2 increase relating to inaccuracies in the accounting for long term contracts and bad debts in our environmental segment’s Polish operations;

· Tax - $0.3 increase resulting from inaccuracies in the accounting for income tax deductions in our domestic operations; and

· $0.4 increase for other insignificant errors we have aggregated together.

Note 5: 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:

Note 7:  INCOME TAXES

Our effective tax rate for the three months ended March 31, 2012 and 2011 was 26.5% and 23.8%, 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 8: 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:

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

	(Effective Portion)
Derivatives in Cash Flow Hedging Relationships	Three Months Ended March 31,
	2012		2011 Restated
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:

		Amount of Gain or
		(Loss) Recognized in
		Income on Derivatives
Derivatives Not Designated as Hedging Instruments	Location of Gain	Three Months Ended
	or (Loss)	March 31,
	Recognized in
	Income on	2012			2011
	Derivatives	Restated			Restated
Foreign currency exchange contracts	Other, net	$	(0.4	)	$	(1.1	)

We did not have any significant foreign exchange derivative instruments outstanding as of March 31, 2012 or December 31, 2011.

Note 9:  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.

21

AMCOL INTERNATIONAL CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(Dollars in millions)

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

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.

Note 10: 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:

	Three Months Ended March 31,

Change from net income attributable to AMCOL shareholders and transfers from noncontrolling interest	$	13.4	$	4.3

Note 11: 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.

Item 2:  Management’s Discussion and Analysis of Financial Condition and Results of Operations

Forward-Looking Statements

From time to time, certain statements we make, including statements in this Management's Discussion and Analysis of Financial Condition and Results of Operations section, constitute "forward-looking statements" made in reliance upon the safe harbor contained in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. 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.

24

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.

25

· 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/A 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/A 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 and, as more fully described in Note 2 to the condensed consolidated financial statements contained in this Amendment No. 1, is based on amounts which have been restated.

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 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 Restated			Acquisitions			Foreign Exchange Restated			Total
Minerals and materials		4.6	%		0.0	%		-0.3	%		4.3	%
Environmental		0.3	%		0.0	%		-0.6	%		-0.3	%
Oilfield services		4.4	%		0.0	%		0.0	%		4.4	%
Transportation & intersegment shipping		-0.7	%		0.0	%		0.0	%		-0.7	%
Total		8.6	%		0.0	%		-0.9	%		7.7	%
% of growth		111.7	%		0.0	%		-11.7	%		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 (Restated)		64.1	%		22.4	%		13.5	%		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 100 basis points due to a 250 basis point increase in our minerals and materials segment’s gross margin.

28

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

SG&A expenses increased $4.4 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 $1.7 million provision for estimated losses on certain non-operating assets.

Income tax expense:

Our effective tax rate for the current quarter was 26.5% versus 23.8% in the prior year’s quarter.  Our income tax expense and effective tax rate fluctuated between the periods presented due to distribution of income between taxing jurisdictions.  The current quarter’s income is more heavily concentrated in our domestic operations which typically have a higher income tax rate than our foreign operations.

29

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

	Three Months Ended March 31,
Minerals and Materials	2012 Restated				2011 Restated				2012 vs. 2011
	(Dollars in millions)
Net sales	$	125.2	100.0	%	$	115.8	100.0	%	$	9.4		8.1	%
Cost of sales		91.8	73.3	%		87.8	75.8	%
Gross profit		33.4	26.7	%		28.0	24.2	%		5.4		19.3	%
Selling, general and administrative expenses		11.9	9.5	%		12.0	10.4	%		(0.1	)	-0.8	%
Operating profit		21.5	17.2	%		16.0	13.8	%		5.5		34.4	%

	Three Months Ended March 31,
Minerals and Materials Product Line Sales	2012 Restated		2011 Restated		% change
	(Dollars in millions)
Metalcasting	$	62.8	$	55.2		13.8	%
Specialty materials		26.8		27.4		-2.2	%
Basic minerals		19.5		16.4		18.9	%
Pet products		14.2		15.1		-6.0	%
Other product lines		1.9		1.7		11.8	%
Total		125.2		115.8		8.1	%

Increased selling prices accounted for approximately 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 profit and gross margin.  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 margin, however, increased more than gross margin (340 basis points versus 250 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.

30

Environmental Segment

	Three Months Ended March 31,
Environmental	2012 Restated				2011 Restated				2012 vs. 2011
	(Dollars in Millions)
Net sales	$	51.0	100.0	%	$	51.7	100.0	%	$	(0.7	)	-1.4	%
Cost of sales		36.4	71.4	%		36.4	70.4	%
Gross profit		14.6	28.6	%		15.3	29.6	%		(0.7	)	-4.6	%
Selling, general and administrative expenses		13.7	26.9	%		13.5	26.1	%		0.2		1.5	%
Operating profit (loss)		0.9	1.7	%		1.8	3.5	%		(0.9	)	-50.0	%

	Three Months Ended March 31,
Environmental Product Line Sales	2012 Restated		2011		% change
	(Dollars in millions)
Lining technologies	$	19.3	$	21.6		-10.6	%
Building materials		18.7		17.5		6.9	%
Drilling products		8.6		6.0		43.3	%
Contracting services		4.4		6.6		-33.3	%
Total		51.0		51.7		-1.4	%

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 increased volumes on innovative building materials products, and demand for our drilling products remains strong.

Gross profit decreased as lower volumes caused per unit production costs to increase.   Sales were also slightly more concentrated in lower margin, accessory products.

Although SG&A expenses contain a variety of increases and decreases, none are individually significant and the overall result is that SG&A expenses remained constant between the two periods.   Thus, the trends in operating profit and operating profit margin follow those of gross profit and gross margin.

31

Oilfield Services Segment

	Three Months Ended March 31,
Oilfield Services	2012				2011 Restated				2012 vs. 2011
	(Dollars in Millions)
Net sales	$	55.3	100.0	%	$	45.6	100.0	%	$	9.7		21.3	%
Cost of sales		39.9	72.2	%		32.0	70.2	%
Gross profit		15.4	27.8	%		13.6	29.8	%		1.8		13.2	%
Selling, general and administrative expenses		10.6	19.2	%		7.8	17.1	%		2.8		35.9	%
Operating profit		4.8	8.6	%		5.8	12.7	%		(1.0	)	-17.2	%

The majority of the revenue increase (approximately 61%) occurred in our foreign operations, which primarily focus on water treatment technologies, where we have been successful in gaining new contracts with customers.  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 profit increased with sales, and gross margin decreased as a result of decreased margin in our domestic operations.  Due to the commissioning of new equipment and an increased concentration of land based jobs, our domestic gross margin decreased in our water treatment and coil tubing services.  Gross profit margin 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 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.

Operating profit decreased as the increase in gross profit was overshadowed by the increase in SG&A expenses.  The decrease in gross margin and the increase in SG&A expenses led to the decrease in operating profit margin.

Transportation Segment

	Three Months Ended March 31,
Transportation	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 profit decreased as a result of the decrease in revenues.

32

Corporate Segment

	Three Months Ended March 31,
Corporate	2012 Restated			2011 Restated			2012 vs. 2011
	(Dollars in Millions)
Intersegment sales	$	(7.1	)	$	(7.2	)		0.1
Intersegment cost of sales		(7.2	)		(6.8	)
Gross profit (loss)		0.1			(0.4	)		0.5
Selling, general and administrative expenses		6.1			4.7			1.4		29.8	%
Operating loss		(6.0	)		(5.1	)		(0.9	)	17.6	%

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.

The largest increase in corporate SG&A expenses relates to a $0.7 write-off of certain information technology investments and increased professional fees.

Balance Sheet Review

Our working capital level remained steady; it was $289.8 million at March 31, 2012 and $288.4 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.

Our accumulated other comprehensive loss decreased $10.0 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.

33

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.

	Three Months Ended  March 31,
Cash Flows ($ in millions)	2012 Restated			2011 Restated
Net cash provided by operating activities	$	20.5		$	10.3
Net cash used in investing activities		(15.4	)		(9.8	)
Net cash provided by (used in) financing activities		(12.3	)		(6.3	)

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.

	As at
	March 31,		December 31,
Financial Position ($ in millions)	2012 Restated		2011 Restated
Non-cash working capital	$	272.9	$	264.3
Goodwill & intangible assets		107.4		106.4
Total assets		858.8		849.1
Long-term debt		250.7		260.7
Other long-term obligations		63.6		62.8
Total equity		417.8		394.9

Non-cash working capital at March 31, 2012 increased $8.6 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.

34

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 230 basis points to 37.5%.  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/A, 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 4: Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has re-evaluated the effectiveness of our disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this report. Based on that evaluation, they concluded that, as of the end of such period and due to the material weakness in internal control over financial reporting as outlined below in Changes in Internal Control Over Financial Reporting, our disclosure controls and procedures were not 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.  Notwithstanding the foregoing and for the periods presented, we believe the financial statements included within this report fairly present in all material respects the financial position and results of operations of the Company in conformity with generally accepted accounting principles in the United States.

35

Changes in Internal Control Over Financial Reporting

In our Form 10-K/A for the twelve months ending December 31, 2011, we disclosed the presence of a material weakness in our internal control over financial reporting as of that date.  The material weakness we identified specifically relates to inadequate financial oversight of the European operations within our Environmental segment, especially as it relates to the contracting services product line in which we began reducing our participation in 2011.  Specifically, our internal control over financial reporting did not provide sufficient financial review of these operations by our European leaders and gave certain tasks to employees unqualified to perform them.  These control weaknesses led to errors in our financial statements relating to accounting for inventories, long term customer contracts, and the recognition of bad debt expenses.  These errors led to our restating our financial statements to correctly account for these items as presented in that Form 10-K/A for the annual periods ending December 31, 2011, 2010 and 2009, as well as the financial statements presented in this Form 10-Q/A.

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.  Even before identification of the aforementioned material weakness in internal control over financial reporting and in the normal course of business, we had begun, during the fiscal year ended December 31, 2012, making improvements in our internal control over financial reporting.  These 2012 improvements included:

· Created a new finance position - We created a new position titled Finance Director - EMEA.  This position reports to our Chief Financial Officer and consolidates all financial reporting responsibility for EMEA operations with one person whereas previously it resided with two people who reported to our European management.  A new individual was hired in 2012 to fulfill the responsibilities of this role, including exercising oversight and review of all our European operations.

· Changed the reporting relationship of our accounting staff - In conjunction with the hiring of the new Finance Director - EMEA, we changed the reporting relationships of our finance and accounting staff such that they now report up through our Chief Financial Officer whereas they had previously reported up through their local country general managers.

· Augmented our accounting staff - In addition to the Finance Director - EMEA position, we replaced and in some cases hired additional staff in our foreign operations, including Europe.

· Increased oversight from our domestic accounting staff - Our domestic accounting staff made additional visits to our foreign operations, including those in Europe, to review their local accounting operations and the propriety of accounting for local transactions.  In addition, our domestic accounting staff instituted monthly telephonic reviews with our finance leaders worldwide to discuss the monthly financial results and other accounting matters relating to each subsidiary.  They also instituted quarterly analytical reviews of our foreign entities’ financial statements to vet those results before they are reviewed by our segment finance staff.

· Formalized monthly financial reviews - We formalized and expanded monthly financial statement reviews between our finance and business management team members within all our subsidiaries wherein the discussions of financial results, initiatives, and action items are now documented in a monthly memo.
