NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared by management in accordance with the rules and regulations of the United States Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. Therefore, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2010. In the opinion of management, all adjustments, consisting solely of normal recurring adjustments necessary for a fair presentation of the financial information for the periods indicated, have been included. The results for the three-month period ended April 3, 2011 are not necessarily indicative of the results that may be expected for the year ending December 31, 2011.

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The Company employs accounting policies that are in accordance with U.S. generally accepted accounting principles and require management to make estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported period. Significant estimates include those related to revenue recognition, allowance for doubtful accounts, valuation of inventories, valuation of long-lived assets, goodwill and other intangible assets, pension plan assumptions, income tax, income tax valuation allowances, and litigation and environmental liabilities. Actual results could differ from those estimates.

Note 3. Earnings Per Share (EPS)

Basic earnings per share are based upon the weighted average number of common shares outstanding during the period. Diluted earnings per share are based upon the weighted average number of common shares outstanding during the period assuming the issuance of common shares for all dilutive potential common shares outstanding.

The following table sets forth the computation of basic and diluted earnings per share:

		Three Months Ended
Basic EPS (in millions, except per share data)			April 3, 2011		April 4, 2010

	Net income attributable to MTI	$	15.8	$	15.4

Weighted average shares outstanding			18.3		18.8

Basic earnings per share attributable to MTI		$	0.86	$	0.82

		Three Months Ended
Diluted EPS (in millions, except per share data)			April 3, 2011		April 4, 2010

	Net income attributable to MTI	$	15.8	$	15.4

Weighted average shares outstanding			18.3		18.8
Dilutive effect of stock options and stock units			0.1		--
Weighted average shares outstanding , adjusted		$	18.4	$	18.8

Diluted earnings per share attributable to MTI		$	0.86	$	0.82

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

The weighted average diluted common shares outstanding for the three-months ended April 3, 2011 and April 4, 2010 excludes the dilutive effect of 124,863 and 596,914 options, respectively, as such options had an exercise price in excess of the average market value of the Company's common stock during such period.

Note 4. Income Taxes

As of April 3, 2011, the Company had approximately $6.3 million of total unrecognized income tax benefits. Included in this amount were a total of $5.4 million of unrecognized income tax benefits that, if recognized, would affect the Company’s effective tax rate. While it is expected that the amount of unrecognized tax benefits will change in the next 12 months, we do not expect the change to have a significant impact on the results of operations or the financial position of the Company.

The Company’s accounting policy is to recognize interest and penalties accrued relating to unrecognized income tax benefits as part of its provision for income taxes. The Company had a net reversal of approximately $0.4 million during the first three months of 2011, and has an accrued balance of $1.3 million of interest and penalties accrued as of April 3, 2011.

The Company operates in multiple taxing jurisdictions, both within and outside the U.S. In certain situations, a taxing authority may challenge positions that the Company has adopted in its income tax filings. The Company, with a few exceptions (none of which are material), is no longer subject to U.S. federal, state, local, and international income tax examinations by tax authorities for years prior to 2003.

Note 5. Inventories

The following is a summary of inventories by major category:

(millions of dollars)		April 3, 2011		December 31, 2010
Raw materials	$	32.4	$	34.9
Work-in-process		6.4		6.4
Finished goods		29.4		25.8
Packaging and supplies		21.1		19.4
Total inventories	$	89.3	$	86.5

Note 6. Goodwill and Other Intangible Assets

Goodwill and other intangible assets with indefinite lives are not amortized, but instead are tested for impairment, at least annually. The carrying amount of goodwill was $67.8 million and $67.2 million as of April 3, 2011 and December 31, 2010, respectively. The net change in goodwill since December 31, 2010 was attributable to the effect of foreign exchange.

Acquired intangible assets subject to amortization as of April 3, 2011 and December 31, 2010 were as follows:

	April 3, 2011			December 31, 2010
(millions of dollars)		Gross Carrying Amount	Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Patents and trademarks	$	6.2	3.7	$	6.2	$	3.5
Customer lists		2.7	1.2		2.7		1.2
	$	8.9	4.9	$	8.9	$	4.7

The weighted average amortization period for acquired intangible assets subject to amortization is approximately 15 years. Estimated amortization expense is $0.6 million for each of the next five years through 2015.

Also included in other assets and deferred charges is an intangible asset of approximately $1.1 million which represents the non-current unamortized amount paid to a customer in connection with contract extensions at seven

(Unaudited)

PCC satellite facilities. The current portion of $0.7 million is included in prepaid expenses and other current assets. Such amounts will be amortized as a reduction of sales over the remaining lives of the customer contracts. Approximately $0.2 million was amortized in the first quarter of 2011. Estimated amortization as a reduction of sales is as follows: remainder of 2011 - $0.5 million; 2012 - $0.4 million; 2013 - $0.4 million; 2014 - $0.4 million; 2015 - $0.1 million.

Note 7. Restructuring Costs

2007 Restructuring Program

In the third quarter of 2007, as a result of a change in management and deteriorating financial performance, the Company conducted an in-depth review of all its operations and developed a new strategic focus. The Company initiated a plan to realign its business operations to improve profitability and increase shareholder value by exiting certain businesses and consolidating some product lines. The restructuring resulted in a total workforce reduction of approximately 250, which has been completed.

A reconciliation of the restructuring liability for this program, as of April 3, 2011, is as follows:

(millions of dollars)	Balance as of December 31, 2010		Additional Provisions/ (Reversals)			Cash Expenditures				Balance as of April 3, 2011
Contract termination costs		1.3		(0.2	)		(0.3	)		0.8
Other exit cost		--		0.9			--			0.9
	$	1.3	$	0.7		$	(0.3	)	$	1.7

In the first quarter of 2011, the Company recorded additional restructuring costs associated with our 2007 restructuring of our PCC merchant facility in Germany.

Approximately $0.3 million in payments were made in the first quarter of 2011. The remaining restructuring liability of $1.7 million will be funded from cash flows from operations.

2009 Restructuring Program

In the second quarter of 2009, the Company initiated a program to improve efficiencies through the consolidation of manufacturing operations and reduction of costs.

The restructuring program reduced the workforce by approximately 200 employees worldwide. This reduction in force relates to plant consolidations as well as a streamlining of the corporate and divisional management structures to operate more efficiently.

A reconciliation of the restructuring liability for this program, as of April 3, 2011, is as follows:

(millions of dollars)	Balance as of December 31, 2010		Additional Reversals			Cash Expenditures				Balance as of April 3, 2011
Severance and other employee benefits	$	2.0	$	(0.3	)	$	(0.5	)	$	1.2
	$	2.0	$	(0.3	)	$	(0.5	)	$	1.2

Approximately $0.5 million in severance payments was paid in the first quarter of 2011. The remaining liability of $1.2 million will be funded from cash flows from operations.

Other Restructuring

A reconciliation of other restructuring liabilities as of April 3, 2011, is as follows:

During the first quarter of 2011, the Company entered into a Renminbi (“RMB”) denominated loan agreement at its Refractories facility in China with the Bank of America totaling RMB 10.6 million, or $1.6 million. Principal of this loan is payable in equal annual installments over the next three years. Interest is payable semi-annually and is based upon the official RMB lending rate announced by the People’s Bank of China. The interest rate for the first quarter of 2011 was 6.4%.

As of April 3, 2011, the Company had $183 million of uncommitted short-term bank credit lines, of which approximately $4.4 million were in use.

Note 9. Pension Plans

The Company and its subsidiaries have pension plans covering substantially all eligible employees on a contributory or non-contributory basis. Disclosures for the U.S. plans have been combined with those outside of the U.S. as the international plans do not have significantly different assumptions, and together represent less than 25% of our total benefit obligation.

Note 11. Accounting for Asset Retirement Obligations

The Company records asset retirement obligations for situations in which the Company will be required to incur costs to retire tangible long-lived assets. These are primarily related to its PCC satellite facilities and mining operations. The Company has also recorded the provisions related to conditional asset retirement obligations at its facilities. The Company has recorded asset retirement obligations at all of its facilities except where there are no legal or contractual obligations. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset.

The following is a reconciliation of asset retirement obligations as of April 3, 2011:

(millions of dollars)

Asset retirement liability, December 31, 2010	$	14.7

Note 12. Legal Proceedings

Certain of the Company's subsidiaries are among numerous defendants in a number of cases seeking damages for exposure to silica or to asbestos containing materials. The Company currently has 305 pending silica cases and 28 pending asbestos cases. One new asbestos case was filed in the first quarter of 2011. To date, 1,160 silica cases and 5 asbestos cases have been dismissed. Most of these claims do not provide adequate information to assess their merits, the likelihood that the Company will be found liable, or the magnitude of such liability, if any. Additional claims of this nature may be made against the Company or its subsidiaries. At this time management anticipates that the amount of the Company's liability, if any, and the cost of defending such claims, will not have a material effect on its financial position or results of operations.

The Company has not settled any silica or asbestos lawsuits to date. We are unable to state an amount or range of amounts claimed in any of the lawsuits because state court pleading practices do not require identifying the amount of the claimed damage. The aggregate cost to the Company for the legal defense of these cases since inception was approximately $0.2 million, the majority of which has been reimbursed by Pfizer Inc. pursuant to the terms of certain agreements entered into in connection with the Company's initial public offering in 1992. Our experience has been that the Company is not liable to plaintiffs in any of these lawsuits and the Company does not expect to pay any settlements or jury verdicts in these lawsuits.

Environmental Matters

On April 9, 2003, the Connecticut Department of Environmental Protection issued an administrative consent order relating to our Canaan, Connecticut, plant where both our Refractories segment and Specialty Minerals segment have operations. We agreed to the order, which includes provisions requiring investigation and remediation of contamination associated with historic use of polychlorinated biphenyls ("PCBs") at a portion of the site. The following is the present status of the remediation efforts:

•	Building Decontamination. We have completed the investigation of building contamination and submitted several reports characterizing the contamination. We are awaiting review and approval of these reports by the regulators. Based on the results of this investigation, we believe that the contamination may be adequately addressed by means of encapsulation through painting of exposed surfaces, pursuant to the Environmental Protection Agency's ("EPA") regulations and have accrued such liabilities as discussed below. However, this conclusion remains uncertain pending completion of the phased remediation decision process required by the regulations.
•	Groundwater. We have completed investigations of potential groundwater contamination and have submitted a report on the investigations finding that there is no PCB contamination, but some oil contamination of the groundwater. We expect the regulators to require confirmatory long term groundwater monitoring at the site.
•	Soil. We have completed the investigation of soil contamination and submitted a report characterizing contamination to the regulators. Based on the results of this investigation, we believe that the contamination may be left in place and monitored, pursuant to a site-specific risk assessment, which is underway. However, this conclusion is subject to completion of a phased remediation decision process required by applicable regulations.

We believe that the most likely form of remediation will be to leave existing contamination in place, encapsulate it, and monitor the effectiveness of the encapsulation.

We estimate that the cost of the likely remediation above would approximate $400,000, and that amount has been recorded as a liability on our books and records.

The Company is evaluating options for upgrading the wastewater treatment facilities at its Adams, Massachusetts plant. This work has been undertaken pursuant to an administrative Consent Order originally issued by the Massachusetts Department of Environmental Protection (“DEP”) on June 18, 2002. This order was amended on June 1, 2009 and on June 2, 2010. The amended Order requires the installation of a groundwater containment system following DEP review and approval of certain items submitted by the Company prior to July 1, 2010.

REVIEW REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Minerals Technologies Inc.:

We have reviewed the condensed consolidated balance sheet of Minerals Technologies Inc. and subsidiary companies as of April 3, 2011, and the related condensed consolidated statements of income for the three-month periods ended April 3, 2011 and April 4, 2010, and the related condensed consolidated statements of cash flows for the three-month periods ended April 3, 2011 and April 4, 2010. These condensed consolidated financial statements are the responsibility of the company's management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the condensed consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Minerals Technologies Inc. and subsidiary companies as of December 31, 2010, and the related consolidated statements of income, shareholders' equity, and cash flows for the year then ended (not presented herein); and in our report dated February 25, 2011, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2010 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Executive Summary

Consolidated sales for the first quarter of 2011 increased 4% from the prior year to $262.5 million from $253.5 million. Income from operations grew 7% to $24.7 million in the first quarter of 2011 from $23.1 million in the first quarter of 2010. Included in income from operations for the first quarter of 2011 and 2010 were restructuring costs of $0.2 million and $0.9 million, respectively. Net income increased to $15.8 million as compared to $15.4 million in the prior year.

The Company’s results reflect a strong financial performance as the economic environment in the end markets we serve have stabilized. The Company continues to focus on the execution of its geographic expansion and new product development growth strategies. The Company is constructing three new satellite PCC facilities in India, one new satellite plant in the U.S. and is continuing to pursue market penetration of its FulFillTM portfolio of PCC products. We also continue to execute on our efforts to contain costs and improve productivity throughout the organization.

The Company’s balance sheet as of April 3, 2011 continues to be very strong. Cash, cash equivalents and short-term investments were approximately $400 million. We have available credit lines of $183 million, our debt to equity ratio continues to be a low 11%, and our current ratio was 4.6. Our cash flows from operations were approximately $19 million in the first quarter of 2011.

We face some significant risks and challenges in the future:

The industries we serve, primarily paper, steel, construction and automotive, have been adversely affected by the uncertain global economic climate. Our global business could be adversely affected by decreases in economic activity. Our Refractories segment primarily serves the steel industry. North American and European steel production improved 8.5% in the first quarter of 2011 as compared with fourth quarter 2010, but remains below pre-recession levels. In the paper industry, which is served by our Paper PCC product line, production levels for printing and writing papers within North America and Europe, our two largest markets for the first quarter 2011 were slightly below fourth quarter 2010 and first quarter of the prior year. In addition, our Processed Minerals and Specialty PCC product lines are affected by the domestic building and construction markets and the automotive market. Housing starts in the first quarter of 2011 averaged at approximately 563 thousand units, and were up 5.4% from fourth quarter 2010 levels. Housing starts were down, however, by 8.8% when compared to first quarter 2010. Housing starts were at a peak rate of 2.1 million units in 2005. In the automotive industry, North American car and truck production was up 17% from year end 2010, but remains below pre-recession levels.

·	Some of our customers may experience shutdowns due to further consolidations, or, may face liquidity issues, which could deteriorate the aging of our accounts receivable, increase our bad debt exposure and possibly trigger impairment of assets or realignment of our businesses.
·	Consolidations and rationalizations in the paper and steel industries concentrate purchasing power in the hands of fewer customers, increasing pricing pressure on suppliers such as Minerals Technologies Inc.
·	Most of our Paper PCC sales are subject to long-term contracts that may be terminated pursuant to their terms, or may be renewed on terms less favorable to us.
·	We are subject to volatility in pricing and supply availability of our key raw materials used in our Paper PCC product line and Refractory product line.
·	We continue to rely on China for a significant portion of our supply of magnesium oxide in the Refractories segment, which may be subject to uncertainty in availability and cost.
·	Fluctuations in energy costs have an impact on all of our businesses.
·	Changes in the fair market value of our pension assets, rates of return on assets, and discount rates could have a significant impact on our net periodic pension costs as well as our funding status.
·	As we expand our operations abroad we face the inherent risks of doing business in many foreign countries, including foreign exchange risk, import and export restrictions, and security concerns.
·	The Company’s operations, particularly in the mining and environmental areas (discharges, emissions and greenhouse gases), are subject to regulation by federal, state and foreign authorities and may be subject to, and presumably will be required to comply with, additional laws, regulations and guidelines which may be adopted in the future.

Recently, there was a high magnitude earthquake and tsunami in northern Japan. We have two manufacturing facilities and an administrative office located there. All of our plants are presently operating and there have been minimal supply chain disruptions. However, in our Refractories segment, approximately 15 percent of our Japanese customers were affected, which will have a negative impact on our Japanese refractory sales. We estimate income from operations will be negatively impacted by approximately $0.6 million to $0.7 million for the remainder of the year.

The Company will continue to focus on innovation and new product development and other opportunities for continued growth as follows:

·	Develop multiple high-filler technologies, such as filler-fiber, under the FulfillTM platform of products, to increase the fill rate in freesheet paper and continue to progress with commercial discussions and full-scale paper machine trials.
·	Increase our sales of PCC for paper by further penetration of the markets for paper filling at both freesheet and groundwood mills, particularly in emerging markets.
·	Expand the Company's PCC coating product line using the satellite model.
·	Promote the Company's expertise in crystal engineering, especially in helping papermakers customize PCC morphologies for specific paper applications.
·	Expand PCC produced for paper filling applications by working with industry partners to develop new methods to increase the ratio of PCC for fiber substitutions.
·	Develop unique calcium carbonates and talc products used in the manufacture of novel biopolymers, a new market opportunity.
·	Deploy value-added formulations of refractory materials that not only reduce costs but improve performance and expand our solid core wire line into BRIC and other Asian countries.
·	Deploy operational excellence principles into all aspects of the organization, including system infrastructure and lean principles.
·	Explore selective acquisitions to fit our core competencies in minerals and fine particle technology.

However, there can be no assurance that we will achieve success in implementing any one or more of these opportunities.

Worldwide net sales in the first quarter of 2011 increased 4% to $262.5 million from $253.5 million in the previous year. Foreign exchange had a favorable impact on sales of approximately $1.9 million or less than one percentage point of growth. Sales in the Specialty Minerals segment, which includes the PCC and Processed Minerals product lines, increased 1% to $173.3 million compared with $172.1 million for the same period in 2010. Sales in the Refractories segment for the first quarter of 2011 grew 10% to $89.2 million from $81.4 million in the previous year.

Worldwide net sales of PCC, which is primarily used in the manufacturing process of the paper industry, were $144.8 million as compared with $145.1 million in the prior year. Paper PCC sales declined 1% to $129.2 million in the first quarter of 2011 from $130.7 million in the prior year. Sales were affected by the full quarter effect of the closure of two satellite PCC facilities in the prior year, and to price concessions provided to certain customers in connection with long-term contract extensions. Sales of Specialty PCC increased 8% to $15.6 million from $14.4 million in the prior year. Volumes increased 4% in this product line over the prior year.

Net sales of Processed Minerals products grew 6% in the first quarter of 2011 to $28.5 million from $27.0 million in the first quarter of 2010. This increase was attributable to 10% higher volumes, led by a strong performance in the talc product line which had sales and volume improvements of 12%.

Net sales in the Refractories segment in the first quarter of 2011 grew 10% to $89.2 million from $81.4 million in the prior year. Sales of refractory products and systems to steel and other industrial applications grew 11% to $69.6 million from $62.6 million in the prior year primarily due to increased selling prices and volumes and to higher equipment sales. Sales of metallurgical products within the Refractories segment increased 4 percent to $19.6 million as compared with $18.8 million in the same period last year on volume declines of 13%.

Net sales in the United States grew 2% to $139.4 million in the first quarter of 2011 from $136.6 million in the prior year. International sales in the first quarter of 2011 grew <BTB>5% to $123.1 million from $116.9 million.

Research and development	$	4.9	$	5.1	(5)	%
Restructuring and other costs	$	0.2	$	0.8	(73)	%

Cost of goods sold was 79.8% of sales compared with 79.7% of sales in the prior year. Production margin increased 3% as compared with a 4% increase on sales. In the Specialty Minerals segment, production margin increased 1%, which was in line with the increase in sales. This segment had increased volumes of $1.4 million and improved productivity and cost reductions of $2.3 million as compared to prior year. This was partially offset by net price changes of approximately $1.5 million and higher energy and raw material costs of $1.9 million. In the Refractories segment, production margin increased 7% as compared with a 10% increase in sales. This segment had increased volumes of $2.6 million, price increases of $2.6 million and higher equipment sales of $0.5 million, which were partially offset by $3.9 million in raw material increases.

Marketing and administrative costs increased 4% in the first quarter to $23.1 million from $22.3 million in the prior year. Marketing and administrative costs as a percentage of net sales, however, remained flat at 8.8% of net sales in the current year as compared with the prior year.

Research and development expenses decreased 5% to $4.9 million from $5.1 million in the prior year and represented 1.9% of net sales as compared with 2.0% of net sales in the prior year. The lower costs were primarily due to timing of Paper PCC trials.

Restructuring and other costs during the first quarter of 2011 were $0.2 million and primarily related to additional $0.9 million of restructuring costs associated with our 2007 restructuring of our PCC merchant facility in Germany. This was partially offset by reversals of previously recorded liabilities. In the prior year, restructuring costs of $0.9 million primarily related to railcar lease early termination costs of $0.8 million associated with the announced plant closures of our Franklin, Virginia and Plymouth, North Carolina PCC satellite facilities and additional provisions for severance and other employee benefits associated with our 2009 restructuring program of $0.1 million.

Income from Operations (millions of dollars)		First Quarter 2011		First Quarter 2010	Growth

Income from operations	$	24.7	$	23.0	7	%

The Company recorded income from operations in the first quarter of 2011 of $24.7 million, a 7% increase over income from operations of $23.0 million in the prior year.

Income from operations in the first quarter of 2011 for the Specialty Minerals segment was $19.3 million, as compared to income from operations of $18.4 million in the prior year. Operating income for the Refractories segment was $6.9 million, as compared to an operating profit of $5.8 million in the prior year.

Noncontrolling Interests (millions of dollars)		First Quarter 2011				First Quarter 2010			Growth
Noncontrolling interests	$	0.9			$	0.7			29	%

The increase in the income attributable to noncontrolling interests is due to higher profitability in our joint ventures.

Net Income attributable to MTI (millions of dollars)		First Quarter 2011				First Quarter 2010			Growth
Net income attributable to MTI	$	15.8			$	15.4			3	%

Net income attributable to MTI was $15.8 million in the first quarter of 2011 as compared with income of $15.4 million in the prior year. Diluted earnings per common share were $0.86 per share in the first quarter of 2011 as compared with earnings per common share of $0.82 per share in the prior year.

Liquidity and Capital Resources

Cash provided from operating activities amounted to $19.1 million in the first quarter of 2011 as compared with $33.1 million for the same period last year. Cash flows provided from operations in the first quarter of 2011 were principally used to fund capital expenditures, repurchase shares and pay the Company's dividend to common shareholders. The decrease in cash provided from operations was due primarily to an increase in working capital in the current year as compared with a decrease in the prior year and higher cash payments in the current year for income taxes and other operating liabilities.

Working capital is defined as trade accounts receivable, trade accounts payable and inventories. Working capital increased approximately 4% from December 2010. Total days of working capital increased to 60 days in the first quarter of 2011 from 59 days in the fourth quarter of 2010. This increase was primarily attributable to increases in our trade receivables. The increase in receivables was primarily due to higher sales levels than in the fourth quarter of the prior year.

On February 22, 2010, the Company's Board of Directors authorized the Company's management to repurchase, at its discretion, up to $75 million of the Company’s shares over a two-year period. As of April 3, 2011, 682,305 shares have been repurchased under this program at an average price of approximately $58.31 per share.

The following table summarizes our contractual obligations as of April 3, 2011:

The Company had $183 million in uncommitted short-term bank credit lines, of which $4.4 million were in use at April 3, 2011. The credit lines are primarily in the US, with approximately $13 million or 7% outside the US. The credit lines are generally one year in term at competitive market rates at large well- established institutions. The Company typically uses its available credit lines to fund working capital requirement or local capital spending needs. We anticipate that capital expenditures for 2011 should be between $50 million and $65 million, principally related to the construction of PCC plants and other opportunities that meet our strategic growth objectives. We expect to meet our other long-term financing requirements from internally generated funds, uncommitted bank credit lines and, where appropriate, project financing of certain satellite plants. The aggregate maturities of long-term debt are as follows: 2011 - $0.5 million; 2012 - $8.5 million; 2013 - $77.0 million; 2014 - $8.2 million; thereafter - $0.0 million.

On an ongoing basis, we evaluate our estimates and assumptions, including those related to revenue recognition, allowance for doubtful accounts, valuation of inventories, valuation of long-lived assets, pension plan assumptions, stock-based compensation assumptions, income taxes, income tax valuation allowances and litigation and environmental liabilities. We base our estimates on historical experience and on other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that can not readily be determined from other sources. There can be no assurance that actual results will not differ from those estimates.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk represents the risk of loss that may impact our financial position, results of operations or cash flows due to adverse changes in market prices and foreign currency and interest rates. We are exposed to market risk because of changes in foreign currency exchange rates as measured against the U.S. dollar. We do not anticipate that near-term changes in exchange rates will have a material impact on our future earnings or cash flows. However, there can be no assurance that a sudden and significant decline in the value of foreign currencies would not have a material adverse effect on our financial condition and results of operations. Approximately 52% of our bank debt bears interest at variable rates; therefore our results of operations would only be affected by interest rate changes to such outstanding bank debt. An immediate 10 percent change in interest rates would not have a material effect on our results of operations over the next fiscal year.

We do not enter into derivatives or other financial instruments for trading or speculative purposes. When appropriate, we enter into derivative financial instruments, such as forward exchange contracts and interest rate swaps, to mitigate the impact of foreign exchange rate movements and interest rate movements on our operating results. The counterparties are major financial institutions. Such forward exchange contracts, hedges and interest rate swaps would not subject us to additional risk from exchange rate or interest rate movements because gains and losses on these contracts would offset losses and gains on the assets, liabilities, and transactions being hedged.

We have open forward exchange contracts to purchase approximately $1.7 million of foreign currencies as of April 3, 2011. The contracts mature between April 2011 and July 2011. The fair value of these instruments at April 3, 2011 was a liability of less than $0.1 million.

In 2008 the Company entered into forward contracts to sell 30 million Euros as a hedge of its net investment in Europe. These contracts mature in October 2013. The fair value of these instruments at April 3, 2011 was an asset of $1.0 million.

ITEM 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, and under the supervision and with participation of the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, the Company carried out an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures, pursuant to Exchange Act Rule 13a-15(b). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of April 3, 2011.

Changes in Internal Control Over Financial Reporting

There was no change in the Company's internal control over financial reporting during the quarter ended April 3, 2011 that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings

Environmental Matters

•	Building Decontamination. We have completed the investigation of building contamination and submitted several reports characterizing the contamination. We are awaiting review and approval of these reports by the regulators. Based on the results of this investigation, we believe that the contamination may be adequately addressed by means of encapsulation through painting of exposed surfaces, pursuant to the Environmental Protection Agency's ("EPA") regulations and have accrued such liabilities as discussed below. However, this conclusion remains uncertain pending completion of the phased remediation decision process required by the regulations.
•	Groundwater. We have completed investigations of potential groundwater contamination and have submitted a report on the investigations finding that there is no PCB contamination, but some oil contamination of the groundwater. We expect the regulators to require confirmatory long term groundwater monitoring at the site.
•	Soil. We have completed the investigation of soil contamination and submitted a report characterizing contamination to the regulators. Based on the results of this investigation, we believe that the contamination may be left in place and monitored, pursuant to a site-specific risk assessment, which is underway. However, this conclusion is subject to completion of a phased remediation decision process required by applicable regulations.

We believe that the most likely form of remediation will be to leave existing contamination in place, encapsulate it, and monitor the effectiveness of the encapsulation.

We estimate that the cost of the likely remediation above would approximate $400,000, and that amount has been recorded as a liability on our books and records.

Table of Contents

engineering reviews completed in 2005 indicate that the estimated cost of wastewater treatment upgrades to operate this facility beyond 2024 may be between $6 million and $8 million. The groundwater containment system, required to allow continued operation of the wastewater treatment ponds pending the required upgrades, will be up to $3 million. The Company estimates that the remaining remediation costs would approximate $400,000, which has been accrued as of April 3, 2011.

The Company and its subsidiaries are not party to any other material pending legal proceedings, other than routine litigation incidental to their businesses.

ITEM 5. Other Information

Section 1503 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Reform Act”) contains certain reporting requirements regarding coal or other mine safety. The Company, through its subsidiaries Specialty Minerals Inc. and Barretts Minerals Inc., operates four mines or mine complexes in the United States. The operation of our 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.

The following table sets forth the information required by the Reform Act with respect to each mine or mine complex for which we are the operator for the period January 1, 2011 to April 3, 2011 (number of occurrences, except for proposed assessment dollar values):

Table of Contents

Mining Complex	Section 104(a) – S&S	Section 104(b)	Section 104(d)	Section 110(b)(2)	Section 107(a)	Proposed Assessments	Fatalities

Adams, MA	2	0	0	0	0	$1,758	0
Dillon, MT**	1	0	0	0	0	$2,618	0

*	As of the date of this report, we have not received proposed assessments for violations issued during this period for these locations.

**	Our mining complex at Dillon, MT consists of three mines separately identified by MSHA.

(A)	The 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 we received a citation from MSHA.

(B)	The total number of orders issued under section 104(b) of the Mine Act.

(C)	The total number of citations and orders for unwarrantable failure of the Company to comply with mandatory health or safety standards under section 104(d) of the Mine Act.

(D)	The total number of flagrant violations under section 110(b)(2) of the Mine Act.

(E)	The total number of imminent danger orders issued under section 107(a) of the Mine Act.

(F)	The total dollar value of proposed assessments from MSHA under the Mine Act.

(G)	The total number of mining-related fatalities.

During the period January 1, 2011 to April 3, 2011, we did not receive any written notice from MSHA, with respect to any mine or mine complex for which we are the operator, of (A) 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 mine health and safety hazards under section 104(e) of the Mine Act or (B) the potential to have such a pattern.

As of April 3, 2011, we had no pending legal actions before the Federal Mine Safety and Health Review Commission involving a mine or mine complex for which we are the operator.

EXHIBIT 99

RISK FACTORS

Our business faces significant risks. These risks include those described below and may include additional risks and uncertainties not presently known to us. Our business, financial condition and results of operations could be materially adversely affected by any of these risks. These risks should be read in conjunction with the other information in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, and this Quarterly Report on Form 10-Q.

·	Worldwide general economic, business, and industry conditions has had, and may continue to have, an adverse effect on the Company’s results.
	The global economic downturn has caused, among other things, declining consumer and business confidence, volatile raw material prices, instability in credit markets, high unemployment, fluctuating interest rates and exchange rates, and other challenges. The Company’s business and operating results have been and may continue to be adversely affected by these global economic conditions. The Company’s customers and potential customers may experience deterioration of their businesses, cash flow shortages, and difficulty obtaining financing. As discussed below, the industries we serve, primarily paper, steel, construction and automotive, have been particularly adversely affected by the uncertain global economic climate due to the cyclical nature of their businesses. As a result, existing or potential customers may reduce or delay their growth and investments and their plans to purchase products, and may not be able to fulfill their obligations in a timely fashion. Further, suppliers could experience similar conditions, which could affect their ability to fulfill their obligations to the Company. Adversity within capital markets may impact future return on pension assets, thus resulting in greater future pension costs that impact the company’s results. The timing, strength or duration of any recovery in the global economic markets remains uncertain, and there can be no assurance that market conditions will improve in the near future or that our results will not continue to be materially and adversely affected.
·	The Company’s operations are subject to the cyclical nature of its customers' businesses and we may not be able to mitigate that risk.
	The majority of the Company's sales are to customers in industries that have historically been cyclical: paper, steel, construction, and automotive. These industries had been particularly adversely affected by the uncertain global economic climate in late 2008 and in 2009. Our Refractories segment primarily serves the steel industry. North American and European steel production improved in 2010 from 2009, but was approximately 20% below pre-recession levels. In the paper industry, which is served by our Paper PCC product line, production levels for printing and writing papers within North America and Europe, our two largest markets improved in 2010 but were approximately 15% below pre-recession levels. In addition, our Processed Minerals and Specialty PCC product lines are affected by the domestic building and construction markets and the automotive market. Housing starts in 2010 averaged approximately 585 thousand units, a 6% improvement over 2009. Housing starts were at a peak rate of 2.1 million units in 2005. In the automotive industry, North American car and truck production was up 38% in 2010, but remains well below pre-recession levels. Demand for our products is subject to these trends. The Company has taken steps to reduce its exposure to variations in its customers' businesses, including by diversifying its portfolio of products and services; through geographic expansion, and by structuring most of its long-term satellite PCC contracts to provide a degree of protection against declines in the quantity of product purchased, since the price per ton of PCC generally rises as the number of tons purchased declines. In addition, many of the Company's product lines lower its customers' costs of production or increase their productivity, which should encourage them to use its products. However, there can be no assurance that these efforts will mitigate the risks of our dependence on these industries. Continued weakness in the industries we serve has had, and may in the future have, an adverse effect on sales of our products and our results of operations. A
	continued or renewed economic downturn in one or more of the industries or geographic regions that the Company serves, or in the worldwide economy, could cause actual results of operations to differ materially from historical and expected results.

· ·	The Company’s results could be adversely affected if it is unable to effectively achieve and implement its growth initiatives.
	Sales and income growth of the Company depends upon a number of uncertain events, including the outcome of the Company's strategies of increasing its penetration into geographic markets such as the BRIC (Brazil, Russia, India, China) countries and other Asian and Eastern European countries; increasing its penetration into product markets such as the market for papercoating pigments and the market for groundwood paper pigments; increasing sales to existing PCC customers by increasing the amount of PCC used per ton of paper produced; developing, introducing and selling new products such as the FulfillTM family of products for the paper industry. Difficulties, delays or failure of any of these strategies could affect the future growth rate of the Company. Our strategy also anticipates growth through future acquisitions. However, our ability to identify and consummate any future acquisitions on terms that are favorable to us may be limited by the number of attractive acquisition targets, internal demands on our resources and our ability to obtain financing. Our success in integrating newly acquired businesses will depend upon our ability to retain key personnel, avoid diversion of management’s attention from operational matters, and integrate general and administrative services. In addition, future acquisitions could result in the incurrence of additional debt, costs and contingent liabilities. Integration of acquired operations may take longer, or be more costly or disruptive to our business, than originally anticipated, and it is also possible that expected synergies from future acquisitions may not materialize. We also may incur costs and divert management attention with regard to potential acquisitions that are never consummated.
· ·	The Company’s sales of PCC could be adversely affected by our failure to renew or extend long term sales contracts for our satellite operations.
	The Company's sales of PCC to paper customers are typically pursuant to long-term evergreen agreements, initially ten years in length, with paper mills where the Company operates satellite PCC plants. Sales pursuant to these contracts represent a significant portion of our worldwide Paper PCC sales, which were $496.6 million in 2010, or approximately 49.5% of the Company’s net sales. The terms of many of these agreements have been extended or renewed in the past, often in connection with an expansion of the satellite plant. However, failure of a number of the Company's customers to renew or extend existing agreements on terms as favorable to the Company as those currently in effect, or at all, could have a substantial adverse effect on the Company's results of operations, and could also result in impairment of the assets associated with the PCC plant.
· ·	The Company’s sales could be adversely affected by consolidation in customer industries, principally paper and steel.
	Several consolidations in the paper industry have taken place in recent years. These consolidations could result in partial or total closure of some paper mills where the Company operates PCC satellites. Such closures would reduce the Company's sales of PCC, except to the extent that they resulted in shifting paper production and associated purchases of PCC to another location served by the Company. Similarly, consolidations have occurred in the steel industry. Such consolidations in the two major industries we serve concentrate purchasing power in the hands of a smaller number of papermakers and steel manufacturers, enabling them to increase pressure on suppliers, such as the Company. This increased pressure could have an adverse effect on the Company's results of operations in the future.
· ·	The Company is subject to stringent regulation in the areas of environmental, health and safety, and tax, and may incur unanticipated costs or liabilities arising out of claims for various legal, environmental and tax matters.
	The Company’s operations are subject to international, federal, state and local governmental environmental, health and safety, tax and other laws and regulations. We have expended, and may be required to expend in the future, substantial funds for compliance with such laws and regulations. In addition, future events, such as changes to or modifications of interpretations of existing laws and regulations, or enforcement polices, or further investigation or evaluation of the potential environmental impacts of operations or health hazards of certain products, may give rise to additional compliance and other costs that could have a material adverse effect on the Company. State, national, and international governments and agencies have been evaluating climate-related legislation and regulation that would restrict emissions of greenhouse gases in areas in which we conduct business, and some such legislation and regulation have already been enacted or adopted. Enactment of climate-related legislation or adoption of regulation that restrict emissions of greenhouse gases in areas in which we conduct business could have an adverse effect on our operations or demand for our products. Our manufacturing processes, particularly the manufacturing process for PCC, use a significant amount of energy and, should energy prices increase as a result of such legislation or regulation, we may not be able to pass these increased costs on to purchasers of our products. We cannot predict if or when currently proposed or additional laws and regulations regarding climate change or other environmental or health and safety concerns will be enacted or adopted. Moreover, changes in tax regulation and international tax treaties could reduce the financial performance of our foreign operations.

	The Company is currently a party in various litigation matters and tax and environmental proceedings, and may be subject to claims in the future. While the Company carries liability insurance, which it believes to be appropriate to its businesses, and has provided reserves for current matters, which it believes to be adequate, an unanticipated liability, arising out of such a litigation matter or a tax or environmental proceeding could have a material adverse effect on the Company’s financial condition or results of operations.
· ·	Delays or failures in new product development could adversely affect the Company’s operations.
	The Company’s future business success will depend in part upon its ability to maintain and enhance its technological capabilities, to respond to changing customer needs, and to successfully anticipate or respond to technological changes on a cost-effective and timely basis. The Company is engaged in a continuous effort to develop new products and processes in all of its product lines. Difficulties, delays or failures in the development, testing, production, marketing or sale of such new products could cause actual results of operations to differ materially from our expected results.
· ·	The Company’s ability to compete is dependent upon its ability to defend its intellectual property against infringement.
	The Company's ability to compete is based in part upon proprietary knowledge, both patented and unpatented. The Company's ability to achieve anticipated results depends in part on its ability to defend its intellectual property against inappropriate disclosure as well as against infringement. In addition, development by the Company's competitors of new products or technologies that are more effective or less expensive than those the Company offers could have a material adverse effect on the Company's financial condition or results of operations.
· ·	The Company’s operations could be impacted by the increased risks of doing business abroad.
	The Company does business in many areas internationally. Approximately 47% of our sales in 2010 were derived from outside the United States and we have significant production facilities which are located outside of the United States. We have in recent years expanded our operations in emerging markets, and we plan to continue to do so in the future, particularly in China, India and Eastern Europe. Some of our operations are located in areas that have experienced political or economic instability, including Indonesia, Brazil, Thailand, China and South Africa. As the Company expands its operations overseas, it faces increased risks of doing business abroad, including inflation, fluctuation in interest rates, changes in applicable laws and regulatory requirements, export and import restrictions, tariffs, nationalization, expropriation, limits on repatriation of funds, civil unrest, terrorism, unstable governments and legal systems, and other factors. Adverse developments in any of the areas in which we do business could cause actual results to differ materially from historical and expected results. In addition, a significant portion of our raw material purchases and sales outside the United States are denominated in foreign currencies, and liabilities for non-U.S. operating expenses and income taxes are denominated in local currencies. Our financial results therefore will be affected by changes in foreign currency rates. Accordingly, reported sales, net earnings, cash flows and fair values have been and in the future will be affected by changes in foreign exchange rates. Our overall success as a global business depends, in part, upon our ability to succeed in differing legal, regulatory, economic, social and political conditions. We cannot assure you that we will implement policies and strategies that will be effective in each location where we do business.
· ·	The Company’s operations are dependent on the availability of raw materials and increases in costs of raw materials or energy could adversely affect our financial results.
	The Company depends in part on having an adequate supply of raw materials for its manufacturing operations, particularly lime and carbon dioxide for the PCC product line, and magnesia and alumina for its Refractory operations and on having adequate access to ore reserves of appropriate quality at its mining operations. Purchase prices and availability of these critical raw materials are subject to volatility. At any given time, we may be unable to obtain an adequate supply of these critical raw materials on a timely basis, on price and other terms, or at all. While most such raw materials are readily available, the Company purchases a significant portion of its magnesia requirements from sources in China. The price and availability of magnesia have fluctuated in the past and they may fluctuate in the future. Price increases for certain other of our raw materials, as well as increases in energy prices, have also affected our business. Our ability to recover increased costs is uncertain. The Company and its customers will typically negotiate reasonable price adjustments in order to recover a portion of these rapidly escalating costs. While the contracts pursuant to which we construct and operate our satellite PCC plants generally adjust pricing to reflect increases in costs resulting from inflation, there is a time lag before such price adjustments can be implemented. In 2008, increased raw materials affected our Specialty Minerals segment by $24 million, partially offset by recovery of raw material costs through price increases of $16 million, while raw material prices affected our Refractories segment by $34 million, partially offset by recovery of raw material costs through price increases of $31 million. In 2009 and 2010, however, the impact of such price increased was not material.

	We cannot predict whether, and how much, prices for our key raw materials will increase in the future. Changes in the costs or availability of such raw materials, to the extent we cannot recover them in price increases to our customers, could adversely affect the Company’s results of operations.
·	The Company operates in very competitive industries, which could adversely affect our profitability.
	The Company has many competitors. Some of our principal competitors have greater financial and other resources than we have. Accordingly, these competitors may be better able to withstand changes in conditions within the industries in which we operate and may have significantly greater operating and financial flexibility than we do. As a result of the competitive environment in the markets in which we operate, we currently face and will continue to face pressure on the sales prices of our products from competitors, which could reduce profit margins.
·	Production facilities are subject to operating risks and capacity limitations that may adversely affect the Company’s financial condition or results of operations.
	The Company is dependent on the continued operation of its production facilities. Production facilities are subject to hazards associated with the manufacturing, handling, storage, and transportation of chemical materials and products, including pipeline leaks and ruptures, explosions, fires, inclement weather and natural disasters, mechanical failure, unscheduled downtime, labor difficulties, transportation interruptions, and environmental risks. We maintain property, business interruption and casualty insurance but such insurance may not cover all risks associated with the hazards of our business and is subject to limitations, including deductibles and maximum liabilities covered. We may incur losses beyond the limits, or outside the coverage, of our insurance policies. Further, from time to time, we may experience capacity limitations in our manufacturing operations. In addition, if we are unable to effectively forecast our customers’ demand, it could affect our ability to successfully manage operating capacity limitations. These hazards, limitations, disruptions in supply and capacity constraints could adversely affect financial results.
