Note 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Company Operations

We, AMCOL International Corporation (the “Company”), are a leading producer and marketer of diverse specialty materials with a core expertise in minerals and polymer science.  Through five business segments, performance materials, construction technologies, energy services, transportation, and corporate, we create solutions that enhance the quality, efficiency and sustainability of our customers’ products and services in a growing global marketplace.

Our performance materials segment is a leading supplier of bentonite related products.

Our construction technologies segment provides products for non-residential construction, environmental and infrastructure projects worldwide.

 Our energy services segment offers a range of patented technologies, products and services for both upstream and downstream oil and gas production.

Our transportation segment, which serves our domestic subsidiaries as well as third parties, is a dry van and flatbed carrier and freight brokerage service provider.

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 69% and 73% of the revenue elimination in the six months ended June 30, 2012 and 2011, respectively, and 64% and 74% of the revenue elimination in the three months ended June 30, 2013 and 2012, respectively, represents elimination of shipping revenues between our transportation segment and its domestic sister companies.

A significant portion of the products sold by our performance materials segment and, to a lesser extent, our construction technologies segment, utilize a mineral called bentonite.  Bentonite has several valuable characteristics, including its ability to bind, swell, adsorb, control rheology, soften fabrics, and have its surface modified through chemical and physical reactions. We also develop applications for other specialty minerals, most significantly chromite and leonardite.

We earn revenues from the sale of finished products, provision of services, rental of equipment, and charges for shipping goods and materials to customers.  Our service revenues are derived primarily from our construction technologies, energy services, and transportation segments; our transportation segment is purely service based.

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, 2012, is unaudited.  The condensed consolidated balance sheet as of December 31, 2012 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, 2012.  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 June 30, 2013 and 2012, and our financial position as of June 30, 2013, 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, 2012.

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 and six months ended June 30, 2013.  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 construction technologies segment, which varies due to the seasonal nature of the construction industry, and our energy services segment, which varies due to seasonal weather patterns in its various geographic markets.

Recently Adopted and Recently Issued Accounting Guidance

Adopted:

In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-02 codified in Accounting Standards Codification (“ASC”) Topic 220 – Comprehensive Income which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income.  This ASU requires entities to disclose additional information about reclassification adjustments, including changes in accumulated other comprehensive income balances by component and significant items reclassified out of accumulated other comprehensive income.  Other than additional disclosure requirements, the adoption of this ASU on January 1, 2013 had no impact on our financial statements.

In July 2012, the FASB issued ASU 2012-02, codified in ASC Topic 350 – Intangibles – Goodwill and Other.   This ASU gives entities the option to first assess the qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that an indefinite-lived intangible asset is impaired.  If impairment is indicated, the fair value of the indefinite-lived intangible asset should be determined and the quantitative impairment test should be performed by comparing the fair value with the carrying value in accordance with subtopic 350-30.  If impairment is not indicated, the entity is not required to take further action.  The adoption of this ASU on January 1, 2013 had no impact on our financial statements.

Issued:

In March 2013, the FASB issued ASU 2013-05 codified in ASC Topic 830 – Foreign Currency Matters. This ASU clarifies the applicable guidance relating to a parent entity’s accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. A parent entity is required to release any related cumulative foreign currency translation adjustment from accumulated other comprehensive income into net income in the following circumstances: (i) a parent entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided; (ii) a partial sale of an equity method investment that is a foreign entity; (iii) a partial sale of an equity method investment that is not a foreign entity whereby the partial sale represents a complete or substantially complete liquidation of the foreign entity that held the equity method investment; and (iv) the sale of an investment in a foreign entity. This ASU will become effective for us on January 1, 2014. The impact of this ASU on our financial statements will be considered in the event we initiate any of the transactions described above.

Note 2: EARNINGS PER SHARE

   The following table provides further share information used in calculating our earnings per share for the periods presented herein.  Basic earnings per share was calculated 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 calculated 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.

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 tax expense.  Segment assets are those assets used within each 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 cash equivalents, fixed assets, assets associated with certain employee benefit plans, and other miscellaneous assets.

Note 5: EMPLOYEE BENEFIT PLANS

We have a defined benefit pension plan covering substantially all of our domestic employees hired before January 1, 2004.  We also sponsor a supplementary pension plan that provides benefits in excess of qualified plan limitations for certain employees.  Pension cost for both of our plans is comprised of :

	Defined Benefit Pension Plan						Supplementary Pension Plan

Note 6: INCOME TAXES

Our effective tax rate for the six months ended June 30, 2013 and 2012 was 28.2% and 27.0%, respectively.  For both periods, the rate differs from the U.S. federal statutory rate of 35.0% largely due to depletion deductions, 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 2008.  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.

Interest rate swaps, net of tax	$	1.2	$	-	$	0.8	$	(0.2	)

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 June 30, 2013 and 2012, 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 for the following currencies: British pound sterling (GBP), Chinese renminbi (CYN), Danish kroner (DKK),  Euro, India rupee (INR), Malaysian ringgit (MYR), Norwegian krone (NOK), Polish Zloty (PLN), South African rand (ZAR), Swiss franc (SEK), and Thai baht (THB).  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:

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 – Values are 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 – Values are 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 – Values are based on model based techniques that use unobservable inputs for the asset or liability. These inputs reflect our beliefs about the assumptions market participants would use in pricing the asset or liability.

Deferred compensation plan assets		9.4			-		9.4			-
Supplementary pension plan assets		8.2			-		8.2			-

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.

The carrying value of our long-term debt approximates its fair value as the interest rate is near the current market rate yield.  The fair value of our long-term debt is determined using current applicable rates for similar instruments as of the balance sheet date.  The fair value of long-term debt for disclosure purpose is a Level 3 liability within the fair value category.

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 construction technologies and energy 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 leading producer and marketer of diverse specialty materials with a core expertise in minerals and polymer science.  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.

The principal mineral that we utilize to generate revenues 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 develop applications for other minerals, including chromite ore from our mine in South Africa and leonardite.

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.

23

We operate in five segments:  performance materials, construction technologies, energy services, transportation and corporate.  Both our performance materials and construction technologies segments operate manufacturing facilities in North America, Europe, and the Asia-Pacific region.  Our performance materials segment also owns and operates a chrome mine in South Africa.  Our energy 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 provides trucking services for our domestic performance materials and construction technologies segments as well as third parties.

Our customers are engaged in various end-markets and geographic regions. Customers in the performance 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 construction technologies segment include construction contractors, engineering contractors and government agencies.  The energy 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 and commercial construction industries, impacts our revenues.

A sustainable, profitable business with 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 emerging markets and international markets in general to expand our revenues and earnings over the long-term given the expected growth rates in these areas.  We expect to take advantage of these growing markets, 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.

24

· 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, 2012.  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, 2012.

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, 2012.

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 in conjunction with the accompanying condensed consolidated financial statements.

The following consolidated income statement review and segment analysis discuss the results for the three months ended June 30, 2013 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.

One measure of our sales growth includes determining the amount of growth attributable to organic growth, acquisitions, or foreign currency exchange rate fluctuations.  Organic growth represents growth from operations owned for more than one year whereas acquisitions are those owned for less than one year.  Foreign currency exchange rate fluctuations isolate the impact of currency changes over the prior-year period.  The following table details the components of consolidated sales changes over the prior year’s comparable period:

26

	Organic			Acquisitions			Foreign Exchange			Total
Performance materials		-1.3	%		0.0	%		-0.2	%		-1.5	%
Construction technologies		-2.3	%		0.0	%		0.2	%		-2.1	%

% of change		105.0	%		0.0	%		-5.0	%		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
Performance materials		27.0	%		10.0	%		11.4	%		48.4	%
Construction technologies		8.6	%		9.5	%		3.2	%		21.3	%
Energy services		25.1	%		1.8	%		2.7	%		29.6	%
Transportation & intersegment sales		0.7	%		0.0	%		0.0	%		0.7	%
Total - current year's period		61.4	%		21.3	%		17.3	%		100.0	%
Total from prior year's comparable period		62.8	%		21.7	%		15.5	%		100.0	%

Inter-regional sales in the geographic table above are eliminated in Americas.

Our net sales grew organically and was led by our energy services segment, which increased its sales 27.2%, as our three other major segments experienced a decrease in sales.  A greater portion of our sales were generated in our Asia Pacific region due to the decline in our domestic sales within our performance materials and construction technologies segments.

Gross profit decreased due to lower margins in our energy services and performance materials segments.  In energy services, margins suffered due to increased competition within our land based services, especially coil tubing.   In performance materials, decreased volumes gave rise to decreased margins.

Selling, general and administrative expenses increased $3.4 million and included $1.7 million of reorganizing charges, mostly in our construction technologies segment.  Excluding reorganizing charges, increased employee and employee related expenses were the main drivers of the increased SG&A costs.

The fluctuation in operating profit and operating profit margins follow on from the decrease in gross profit and increased SG&A expenses.  Diluted earnings per share decreased for similar reasons in the 2013 quarter, which also includes $0.06 per share of certain expenses, primarily associated with reorganizing our business operations.

Total		127.2		131.1		-3.0	%

Overall, revenues decreased $3.9 million as the impact of increased selling prices, $1.8 million, was overcome by decreased volumes, a $5.8 million impact.  Volumes decreased the most in our specialty materials product line due to decreased demand and increased competition for our drilling products.  Our metalcasting product line also experienced a decrease in volumes due to lower demand for products, particularly our chormite sand which also faced increased competition.  This product line, however, generated the increase in selling prices within the segment.

Gross profit decreased due to the decrease in sales and the decrease in gross profit margin, which suffered from the negative effect reduced volumes had on economies of scale.  These reductions also caused a decrease in operating profit and operating profit margin.

Decreased volumes account for the entire decrease in revenues and occurred largely in our lining technologies and contracting services product lines.  Our lining technologies products continue to experience decreased demand, and the decrease in contracting services reflects our decision to reduce our involvement in those services.

The decreased revenues led to the decrease in gross profit.  However, efforts to reorganize this segment’s operations are starting to yield margin improvements, reflected in the 160 basis point increase in gross margin.  SG&A expenses increased $2.8 million, $1.5 million of which was incurred as part of the reorganization efforts.  Excluding these reorganization expenses, the increase in SG&A costs results from the inclusion, in the prior year’s quarter, of a $1.0 million gain from the favorable settlement of a customer dispute. The increased SG&A expenses along with the decrease in gross profit gave rise to a decrease in operating profit within the segment.

29

Revenues increased $16.6 million, or 27.2%, due to a $15.1 million increase from our domestic operations.  Our domestic filtration services were in high demand and benefitted from increased work being performed in the Gulf of Mexico.  Our nitrogen and coil tubing services also benefitted from high demand and increased capacity, but this work occurred mostly onshore.

The increased revenues led to increased gross profits.  While our offshore work is typically more profitable, increased competition in our onshore services continued and led to the decrease in gross profit margins.  These factors also led to the increase in operating profits and decrease in operating profit margin.

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
Performance materials		27.4	%		10.0	%		11.6	%		49.0	%
Construction technologies		8.4	%		8.4	%		3.0	%		19.8	%

Total from prior year's comparable period		64.0	%		20.7	%		15.3	%		100.0	%

Inter-regional sales in the geographic table above are eliminated in Americas.  Organic growth drove the increase in sales and was led by our energy services segment as our other four segments each experience decreased revenues.  Energy services increased its revenues 29.6% with 87.5% of the increase occurring in our domestic operations.  Even with that increase, however, a greater proportion of our sales were generated in the Asia Pacific region given the strength of the economic environment there combined with the sluggish environment and decreased sales in the EMEA region.

 Gross profit decreased due to lower margins in our energy services and performance materials segments.  In energy services, margins suffered due to increased competition within our land based services, especially coil tubing.   In performance materials, decreased volumes gave rise to decreased margins.

Selling, general and administrative expenses increased $6.9 million, or 7.9%.  Over half of the increase relates to $3.8 million of expenses incurred to reorganize some of our operations, mostly our construction technologies segment.  Excluding these expenses, increased employee and related expenses accounted for the largest portion of the remaining increase.

The fluctuation in operating profit and operating profit margins follow on from the decrease in gross profit and increased SG&A expenses.

Other net decreased by $1.5 million due mostly to the inclusion, in the prior year's amount, of $1.8 million of losses on certain non-operating assets.

Diluted earnings per share decreased primarily due to the decrease in gross profit and the increase in selling, general and administrative expenses.

Year-to-Date Review of Each Segment’s Results

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

Performance Materials

	Six Months Ended June 30,
Performance Materials	2013				2012				2013 vs. 2012
	(Dollars in millions)
Net sales	$	244.4	100.0	%	$	256.3	100.0	%	$	(11.9	)	-4.6	%
Cost of sales		182.9	74.8	%		187.3	73.1	%
Gross profit		61.5	25.2	%		69.0	26.9	%		(7.5	)	-10.9	%
Selling, general and administrative expenses		26.7	11.0	%		25.0	9.7	%		1.7		6.8	%
Operating profit		34.8	14.2	%		44.0	17.2	%		(9.2	)	-20.9	%

	Six Months Ended June 30,
Performance Materials Product Line Sales	2013		2012		% change
	(Dollars in Millions)
Metalcasting	$	133.2	$	133.8		-0.4	%
Specialty materials		48.6		59.0		-17.6	%
Basic minerals		30.1		33.3		-9.6	%
Pet products		28.0		28.1		-0.4	%
Other product lines		4.5		2.1		114.3	%
Total		244.4		256.3		-4.6	%

Overall, revenues decreased $11.9 million, or 4.6%, due to decreased volumes ($16.4 million) offset by increased prices ($4.5 million).  Our specialty materials product line accounts for nearly all of the decrease in revenues given the decreased demand from our largest fabric care customer and increased competition in our drilling products.

Gross profit decreased due to the decrease in sales and the decrease in gross profit margin.  Gross profit margin decreased due to the negative effect reduced volumes had on economies of scale.  Along with gains on the sales of fixed assets in the prior year that did not recur in the current year’s period, increased employee and employee related expenses drove the increase in SG&A expenses.  The decrease in gross profit and gross profit margins combined with the increased SG&A expenses led to the decrease in operating profit and operating profit margin.

Construction Technologies

	Six Months Ended June 30,
Construction Technologies	2013				2012				2013 vs. 2012

Selling, general and administrative expenses		30.0	30.4	%		26.1	23.3	%		3.9		14.9	%
Operating profit		1.0	1.0	%		7.2	6.4	%		(6.2	)	-86.1	%

Lining technologies	$	38.0	$	46.7		-18.6	%
Building materials		36.9		37.9		-2.6	%
Drilling products		19.4		19.1		1.6	%
Contracting services		4.5		8.6		-47.7	%
Total		98.8		112.3		-12.0	%

The decrease in revenues results entirely from decreased volumes.  The decrease in lining technologies revenues occurred in both our domestic and European regions due to decreased demand.  The decrease in contracting services revenues reflects our intent to reduce our involvement in those services.

Although gross profits decreased due to the decrease in sales and volumes, our efforts to reorganize this segment’s operations are starting to show results as evidenced in the 170 basis point increase in gross profit margin to 31.4%.

SG&A expenses increased $3.9 million, of which $3.2 million relates to expenses incurred in the reorganization.  The increased expenses combined with the fluctuations in gross profit partially offset by the improvement in gross profit margin drove the decrease in operating profit and operating profit margin.

Energy  Services

	Six Months Ended June 30,
Energy Services	2013				2012				2013 vs. 2012
	(Dollars in Millions)
Net sales	$	150.8	100.0	%	$	116.4	100.0	%	$	34.4	29.6	%

Gross profit		40.2	26.7	%		34.6	29.7	%		5.6	16.2	%
Selling, general and administrative expenses		23.2	15.4	%		22.1	19.0	%		1.1	5.0	%
Operating profit		17.0	11.3	%		12.5	10.7	%		4.5	36.0	%

34

Revenues increased $34.4 million, or 29.6%.  Of the increase, $30.1 million of it occurred in our domestic operations.  Our domestic filtration services are experiencing increased demand for services performed offshore in the Gulf of Mexico.  In addition, several service lines, such as coil tubing and nitrogen, have increased their revenues in response to increased demand and additional service capacity, which was gained through the acquisition of additional service equipment.

Gross profit increased due to the increase in sales.  However, gross profit margins decreased as our onshore services, especially coil tubing, faced increased competitive pressures that have reduced selling prices.  However, the SG&A expenses did not increase substantially, even more so in comparison to the rate that sales increased.  These factors led to the increase in operating profit and operating profit margin.

Transportation

	Six Months Ended June 30,
Transportation	2013				2012				2013 vs. 2012
	(Dollars in Millions)
Net sales	$	21.7	100.0	%	$	22.8	100.0	%	$	(1.1	)	-4.8	%

Gross profit		2.3	10.6	%		2.4	10.5	%		(0.1	)	-4.2	%
Selling, general and administrative expenses		1.8	8.3	%		1.9	8.3	%		(0.1	)	-5.3	%
Operating profit		0.5	2.3	%		0.5	2.2	%		(0.0	)	0.0	%

This segment provides services to third parties as well as AMCOL companies within our other segments.  Revenues decreased due to decreased volumes.  However, these operations have become more efficient and made up for the decreased gross profit levels through increased gross profit margin and reduced SG&A expense, resulting in a steady operating profit.

Corporate

	Six Months Ended June 30,
Corporate	2013			2012			2013 vs. 2012
	(Dollars in Millions)
Intersegment sales	$	(16.2	)	$	(14.9	)		(1.3	)

Selling, general and administrative expenses		12.1			11.8			0.3		2.5	%
Operating loss		(12.0	)		(11.7	)		(0.3	)	2.6	%

Intersegment sales are eliminated in our corporate segment.  These are mostly sales between our transportation segment and our performance materials and construction technologies segments as well as sales between our performance materials segment and construction technologies and energy services segments.

35

Corporate SG&A expenses in the prior year period include $0.7 million of impairment expenses associated with certain information technology assets.  Excluding this, SG&A expenses increased $1.0 million in 2013, primarily due to increased professional fee expense related to the restatement of prior year financial statements incurred as part of our 2012 Form 10-K filing.

Balance Sheet Review

	As of
Financial Position	June 30,		December 31,
($ in millions)	2013		2012
Non-cash working capital	$	291.1	$	275.0
Goodwill & intangible assets		101.7		104.1
Total assets		948.1		910.6
Long-term debt		270.2		248.8
Other long-term obligations		68.1		69.4
Total equity		465.0		465.1

Our total assets increased by $37.5 million to $948.1 million as of June 30, 2013 mainly due to increased investment in working capital to support the growth in business.  Non-cash working capital at June 30, 2013 increased 5.9%, or $16.1 million, as compared to the amount at December 31, 2012.  Given the seasonality of our construction technologies and energy services segments, 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.  Investment in and advances to affiliates and joint ventures increased $6.5 million mainly due to an investment in Novinda Corporation that we acquired in January 2013.

Long-term debt increased $21.4 million as borrowings under our debt facilities increased to fund the working capital, capital expenditures, and the Novinda investment noted previously.

Accumulated other comprehensive loss increased $21.3 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 rate between the USD and the AUD, the PLN, the TRY, and the ZAR has fluctuated significantly, causing the majority of the change in this account.

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.

36

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 2012.  Terms of any new facilities, especially interest rates or covenants, may be significantly different from those we currently have.

All of the cash and cash equivalents on our condensed consolidated balance sheet as of June 30, 2013, is held by our international subsidiaries.  Although the cash overseas is significantly less than the amounts these subsidiaries owe to our domestic subsidiaries, our foreign subsidiaries have cash needs which affect the ability to repatriate this cash.  Due to these liquidity needs, we consider our foreign earnings permanently reinvested and have not provided income taxes on approximately $125.6 million of foreign subsidiary earnings as of June 30, 2013.

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.

	Six Months Ended
Cash Flows	June 30,
($ in millions)	2013				2012
Net cash provided by operating activities		$	29.0			$	38.9
Net cash used in investing activities			(47.2	)			(29.9	)
Net cash provided by (used in) financing activities			13.3				(17.0	)

Cash flows from operating activities decreased from the prior year period mainly due to lower net income and increased investment in working capital.

Cash flows used in investing activities increased due to increased capital expenditures.  During the six months ended June 30, 2013, the majority of our capital expenditures occurred in our energy services segment to support the growth in this segment.  We expect our capital expenditures in 2013 to exceed the levels experienced in recent years.  Our investment in Novinda Corporation resulted in a $5.0 million expenditure in 2013 and gave rise to the increase in investments in and advances (to) from affiliates and joint ventures.

Our cash flow from financing activities increased in the current year period as borrowings under our debt facilities increased to fund the working capital, capital expenditures, and the Novinda investment noted previously.  Long-term debt as a percentage of total capitalization increased 190 basis points to 36.8%.  Year-to-date dividends declared were $0.40 per share and $0.36 per share during the six months ended June 30, 2013 and 2012, respectively.

We have approximately $155.3 million of borrowing capacity available from our revolving credit facility as of June 30, 2013.  We are in compliance with the financial covenants related to the revolving credit facility as of the end of the period covered by this report.

           We are party to a number of lawsuits arising in the normal course of business.   Our energy services segment is party to two lawsuits alleging damages caused by our coiled tubing operations in Louisiana; one lawsuit alleges damages of $30 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.

37

Contractual Obligations and Off-Balance Sheet Arrangements

Item 7 of our Annual Report on Form 10-K, for the year ended December 31, 2012 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, 2012 other than those discussed in Part 1, Item 2 of this report.

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 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, 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.

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 June 30, 2013, 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  June 30, 2013, 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 June 30, 2013 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.

Mine Safety Disclosures

1. Total number of violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a mine safety or health hazard under section 104 of the Mine Act for which AMCOL and its subsidiaries received a citation from MSHA

2. Total dollar amount of proposed assessments received from MSHA during the three-month period ended June 30, 2013.

3. This number consists of 1 pending legal action related to contests of proposed penalties referenced in Subpart C of the Mine Act.

4. This number consists of 3 pending legal action related to contests of proposed penalties referenced in Subpart C of the Mine Act.

5. This number consists of 3 pending legal actions related to contests of proposed penalties referenced in Subpart C of the Mine Act.

6. This number consists of 3 pending legal actions related to contests of proposed penalties referenced in Subpart C of the Mine Act.

7. This number consists of 2 pending legal actions related to contests of proposed penalties referenced in Subpart C of the Mine Act.

In evaluating this information, consideration should be given to factors such as: (i) the number of citations and orders will vary depending on the size of the mine, (ii) the number of citations issued will vary from inspector to inspector and mine to mine, and (iii) citations and orders can be contested and appealed, and in that process, are often reduced in severity and amount, and are sometimes dismissed.

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 tax expense. Segment assets are those assets used within each 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 cash equivalents, fixed assets, assets associated with certain employee benefit plans, and other miscellaneous assets.

The following tables set forth certain financial information by segment:

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]

Company Operations

Company Operations

We, AMCOL International Corporation (the “Company”), are a leading producer and marketer of diverse specialty materials with a core expertise in minerals and polymer science. Through five business segments, performance materials, construction technologies, energy services, transportation, and corporate, we create solutions that enhance the quality, efficiency and sustainability of our customers’ products and services in a growing global marketplace.

Our performance materials segment is a leading supplier of bentonite related products.

Our construction technologies segment provides products for non-residential construction, environmental and infrastructure projects worldwide.

Our energy services segment offers a range of patented technologies, products and services for both upstream and downstream oil and gas production.

Our transportation segment, which serves our domestic subsidiaries as well as third parties, is a dry van and flatbed carrier and freight brokerage service provider.

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 69% and 73% of the revenue elimination in the six months ended June 30, 2012 and 2011, respectively, and 64% and 74% of the revenue elimination in the three months ended June 30, 2013 and 2012, respectively, represents elimination of shipping revenues between our transportation segment and its domestic sister companies.

A significant portion of the products sold by our performance materials segment and, to a lesser extent, our construction technologies segment, utilize a mineral called bentonite. Bentonite has several valuable characteristics, including its ability to bind, swell, adsorb, control rheology, soften fabrics, and have its surface modified through chemical and physical reactions. We also develop applications for other specialty minerals, most significantly chromite and leonardite.

We earn revenues from the sale of finished products, provision of services, rental of equipment, and charges for shipping goods and materials to customers. Our service revenues are derived primarily from our construction technologies, energy services, and transportation segments; our transportation segment is purely service based.

Basis of Presentation

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, 2012, is unaudited. The condensed consolidated balance sheet as of December 31, 2012 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, 2012. 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 June 30, 2013 and 2012, and our financial position as of June 30, 2013, 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, 2012.

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 and six months ended June 30, 2013. 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 construction technologies segment, which varies due to the seasonal nature of the construction industry, and our energy services segment, which varies due to seasonal weather patterns in its various geographic markets.

Recently Adopted and Recently Issued Accounting Guidance

Recently Adopted and Recently Issued Accounting Guidance

Adopted:

In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-02 codified in Accounting Standards Codification (“ASC”) Topic 220 – Comprehensive Income which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. This ASU requires entities to disclose additional information about reclassification adjustments, including changes in accumulated other comprehensive income balances by component and significant items reclassified out of accumulated other comprehensive income. Other than additional disclosure requirements, the adoption of this ASU on January 1, 2013 had no impact on our financial statements.

In July 2012, the FASB issued ASU 2012-02, codified in ASC Topic 350 – Intangibles – Goodwill and Other. This ASU gives entities the option to first assess the qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that an indefinite-lived intangible asset is impaired. If impairment is indicated, the fair value of the indefinite-lived intangible asset should be determined and the quantitative impairment test should be performed by comparing the fair value with the carrying value in accordance with subtopic 350-30. If impairment is not indicated, the entity is not required to take further action. The adoption of this ASU on January 1, 2013 had no impact on our financial statements.

Issued:

In March 2013, the FASB issued ASU 2013-05 codified in ASC Topic 830 – Foreign Currency Matters. This ASU clarifies the applicable guidance relating to a parent entity’s accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. A parent entity is required to release any related cumulative foreign currency translation adjustment from accumulated other comprehensive income into net income in the following circumstances: (i) a parent entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided; (ii) a partial sale of an equity method investment that is a foreign entity; (iii) a partial sale of an equity method investment that is not a foreign entity whereby the partial sale represents a complete or substantially complete liquidation of the foreign entity that held the equity method investment; and (iv) the sale of an investment in a foreign entity. This ASU will become effective for us on January 1, 2014. The impact of this ASU on our financial statements will be considered in the event we initiate any of the transactions described above.

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 – Values are 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 – Values are 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 – Values are based on model based techniques that use unobservable inputs for the asset or liability. These inputs reflect our beliefs about the assumptions 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
					Quoted Prices in Active Markets for Identical Assets			Significant Other Observable Inputs				Significant Unobservable Inputs
Description	Asset / (Liability) Balance at
	6/30/2013				(Level 1)			(Level 2)				(Level 3)

Deferred compensation plan assets			10.7				-			10.7				-
Supplementary pension plan assets			8.6				-			8.6				-

					Fair Value Measurements Using
					Quoted Prices in Active Markets for Identical Assets			Significant Other Observable Inputs				Significant Unobservable Inputs
Description	Asset / (Liability) Balance at
	12/31/2012				(Level 1)			(Level 2)				(Level 3)
Interest rate swaps		$	(8.4	)		$	-		$	(8.4	)		$	-
Available-for-sale securities			14.6				14.6			-				-
Deferred compensation plan assets			9.4				-			9.4				-
Supplementary pension plan assets			8.2				-			8.2				-

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.

The carrying value of our long-term debt approximates its fair value as the interest rate is near the current market rate yield. The fair value of our long-term debt is determined using current applicable rates for similar instruments as of the balance sheet date. The fair value of long-term debt for disclosure purpose is a Level 3 liability within the fair value category.

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:

		Fair Value as of
Liability Derivatives	Balance Sheet Location	June 30, 2013				December 31, 2012
Derivatives designated as hedging instruments:
Interest rate swaps	Other long-term liabilities		$	(6.1	)		$	(8.4	)
Interest rate swaps	Accrued liabilities			(0.6	)			-

Cash flow hedges

Derivatives in Cash Flow Hedging Relationships	Amount of Gain or (Loss) Recognized in Other Comprehensive Income on Derivatives (Effective Portion)
	Six Months Ended June 30,						Three Months Ended June 30,
	2013			2012			2013			2012
Interest rate swaps, net of tax		$	1.2		$	-		$	0.8		$	(0.2	)

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 June 30, 2013 and 2012, 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 for the following currencies: British pound sterling (GBP), Chinese renminbi (CYN), Danish kroner (DKK), Euro, India rupee (INR), Malaysian ringgit (MYR), Norwegian krone (NOK), Polish Zloty (PLN), South African rand (ZAR), Swiss franc (SEK), and Thai baht (THB). 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:

	Location of	Amount of Gain or (Loss) Recognized in Income on Derivatives
	Gain or (Loss) Recognized in	Six Months Ended June 30,							Three Months Ended June 30,

Foreign currency exchange contracts	Other, net		$	(0.9	)		$	0.3		$	(1.0	)		$	0.7

We did not have any significant foreign exchange derivative instruments outstanding as of June 30, 2013 or December 31, 2012.

OTHER CHARGES

Note 10: REORGANIZING CHARGES

Our results for the three and six months ended June 30, 2013 include certain expenses associated with reorganizing our operations. These reorganization efforts mainly relate to our operations in Europe to close or reorganize certain offices there, improve our cost structure, and increase operating efficiencies. The following table outlines the amount of expenses, where they were recognized in our condensed consolidated statements of income, and the segments they relate to:

Six Months Ended June 30, 2013	Performance Materials			Construction Technologies
Cost of sales line:
Employee termination and other benefits		$	-		$	0.7
Selling, general and administrative expenses line:
Employee termination and other benefits			0.6			2.6
Non-cash impairment charges (1)						0.6
Total		$	0.6		$	3.9

Three Months Ended June 30, 2013	Performance Materials		Construction Technologies
Cost of sales line:
Employee termination and other benefits	$	-	$	0.2
Selling, general and administrative expenses line:
Employee termination and other benefits		0.2		0.9
Non-cash impairment charges (1)				0.6
Total	$	0.2	$	1.7

(1) Non-cash impairment charges relate to write-down of certain assets held-for-sale to their estimated fair values based on a third-party appraisal (a Level 2 fair value input).

At June 30, 2013, we had $1.8 included within accrued liabilities within our condensed consolidated balance sheets for cash expenditures needed to satisfy remaining obligations under these reorganization initiatives. We expect to pay these amounts by the end of 2013.

INCOME TAXES

Note 6: INCOME TAXES

Our effective tax rate for the six months ended June 30, 2013 and 2012 was 28.2% and 27.0%, respectively. For both periods, the rate differs from the U.S. federal statutory rate of 35.0% largely due to depletion deductions, 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 2008. In general, the United States Internal Revenue Service (“IRS”) has examined our federal income tax returns for all years through 2009.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Note 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Company Operations

We, AMCOL International Corporation (the “Company”), are a leading producer and marketer of diverse specialty materials with a core expertise in minerals and polymer science. Through five business segments, performance materials, construction technologies, energy services, transportation, and corporate, we create solutions that enhance the quality, efficiency and sustainability of our customers’ products and services in a growing global marketplace.

Our performance materials segment is a leading supplier of bentonite related products.

Our construction technologies segment provides products for non-residential construction, environmental and infrastructure projects worldwide.

Our energy services segment offers a range of patented technologies, products and services for both upstream and downstream oil and gas production.

Our transportation segment, which serves our domestic subsidiaries as well as third parties, is a dry van and flatbed carrier and freight brokerage service provider.

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 69% and 73% of the revenue elimination in the six months ended June 30, 2012 and 2011, respectively, and 64% and 74% of the revenue elimination in the three months ended June 30, 2013 and 2012, respectively, represents elimination of shipping revenues between our transportation segment and its domestic sister companies.

A significant portion of the products sold by our performance materials segment and, to a lesser extent, our construction technologies segment, utilize a mineral called bentonite. Bentonite has several valuable characteristics, including its ability to bind, swell, adsorb, control rheology, soften fabrics, and have its surface modified through chemical and physical reactions. We also develop applications for other specialty minerals, most significantly chromite and leonardite.

We earn revenues from the sale of finished products, provision of services, rental of equipment, and charges for shipping goods and materials to customers. Our service revenues are derived primarily from our construction technologies, energy services, and transportation segments; our transportation segment is purely service based.

The composition of our revenues by segment is as follows:

	Six Months Ended
	June 30,
	2013			2012
Performance materials		49	%		52	%
Construction technologies		20	%		23	%
Energy services		30	%		24	%
Transportation		4	%		5	%
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, 2012, is unaudited. The condensed consolidated balance sheet as of December 31, 2012 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, 2012. 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 June 30, 2013 and 2012, and our financial position as of June 30, 2013, 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, 2012.

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 and six months ended June 30, 2013. 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 construction technologies segment, which varies due to the seasonal nature of the construction industry, and our energy services segment, which varies due to seasonal weather patterns in its various geographic markets.

Recently Adopted and Recently Issued Accounting Guidance

Adopted:

In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-02 codified in Accounting Standards Codification (“ASC”) Topic 220 – Comprehensive Income which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income. This ASU requires entities to disclose additional information about reclassification adjustments, including changes in accumulated other comprehensive income balances by component and significant items reclassified out of accumulated other comprehensive income. Other than additional disclosure requirements, the adoption of this ASU on January 1, 2013 had no impact on our financial statements.

In July 2012, the FASB issued ASU 2012-02, codified in ASC Topic 350 – Intangibles – Goodwill and Other. This ASU gives entities the option to first assess the qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that an indefinite-lived intangible asset is impaired. If impairment is indicated, the fair value of the indefinite-lived intangible asset should be determined and the quantitative impairment test should be performed by comparing the fair value with the carrying value in accordance with subtopic 350-30. If impairment is not indicated, the entity is not required to take further action. The adoption of this ASU on January 1, 2013 had no impact on our financial statements.

Issued:

In March 2013, the FASB issued ASU 2013-05 codified in ASC Topic 830 – Foreign Currency Matters. This ASU clarifies the applicable guidance relating to a parent entity’s accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. A parent entity is required to release any related cumulative foreign currency translation adjustment from accumulated other comprehensive income into net income in the following circumstances: (i) a parent entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided; (ii) a partial sale of an equity method investment that is a foreign entity; (iii) a partial sale of an equity method investment that is not a foreign entity whereby the partial sale represents a complete or substantially complete liquidation of the foreign entity that held the equity method investment; and (iv) the sale of an investment in a foreign entity. This ASU will become effective for us on January 1, 2014. The impact of this ASU on our financial statements will be considered in the event we initiate any of the transactions described above.

EARNINGS PER SHARE [Abstract]

Share information used in computing earnings per share

The following table provides further share information used in calculating our earnings per share for the periods presented herein. Basic earnings per share was calculated 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 calculated 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.

Reclamation liability

We mine various minerals using a surface mining process that requires the removal of overburden. In certain areas and under various governmental regulations, we are obligated to restore the land comprising each mining site to its original condition at the completion of the mining activity. We include an estimate of this reclamation liability in our condensed consolidated balance sheets; it is adjusted to reflect the passage of time, current activities, and changes in estimated future cash outflows. A reconciliation of the activity within our reclamation liability is as follows:
