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, 2005. 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 2, 2006 are not necessarily indicative of the results that may be expected for the year ending December 31, 2006.

Note 2. Summary of Significant Accounting Policies

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Significant improvements are capitalized, while maintenance and repair expenditures are charged to operations as incurred. The Company capitalizes interest cost as a component of construction in progress. In general, the straight-line method of depreciation is used for financial reporting purposes and accelerated methods are used for U.S. and certain foreign tax reporting purposes. The annual rates of depreciation are 3% - 6.67% for buildings, 6.67% - 12.5% for machinery and equipment, 8% - 12.5% for furniture and fixtures and 12.5% - 25% for computer equipment and software-related assets. The estimated useful lives of precipitated calcium carbonate ("PCC") production facilities and machinery and equipment pertaining to its natural stone mining and processing plants and its chemical plants are 15 years.

Property, plant and equipment are depreciated over their useful lives. Useful lives are based on management's estimates of the period that the assets can generate revenue, which does not necessarily coincide with the remaining term of a customer's contractual obligation to purchase products made using those assets. The Company's sales of PCC are predominantly pursuant to long-term evergreen contracts, initially ten years in length, with paper mills at which the Company operates satellite PCC plants. The terms of many of these agreements have been extended, often in connection with an expansion of the satellite PCC plant. As of April 2, 2006, the Company continues to supply PCC at one location at which the PCC contract has expired and one location, representing one unit of PCC production, at which the host mill has provided notice to the Company of its plans to cancel the PCC supply contract upon its expiration in 2006. Failure of a PCC customer to renew an agreement or continue to purchase PCC from a Company facility could result in an impairment of assets charge or accelerated depreciation at such facility.

On March 21, 2006, the Company ceased operation of a one-unit satellite PCC facility in Park Falls, Wisconsin, after the paper company shut down its mill and filed for bankruptcy protection. The paper company is presently seeking a buyer for its mill and if successful, the Company believes it would continue to supply PCC from its satellite facility. If the Company does not resume production from its satellite facility, we could incur an impairment charge of approximately $0.6 million.

Depletion of mineral reserves is determined on a unit-of-extraction basis for financial reporting purposes and on a percentage depletion basis for tax purposes.

Inventories

Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first out (FIFO) method.

Effective January 1, 2006, the Company has adopted SFAS No. 151, "Inventory Costs - an Amendment of ARB No. 43, Chapter 4." As required by this statement, items such as idle facility expense, excessive spoilage, freight, handling costs and re-handling costs are recognized as current period charges. In addition, the allocation of fixed production overheads to the costs of conversion should be based upon the normal capacity of the production facility. Fixed overhead costs associated with idle capacity are expensed as incurred. SFAS No. 151 did not have a material impact on our results of operations during the first quarter.

Stripping Costs Incurred During Production

As further discussed in Note 8 to the condensed consolidated financial statements, effective January 1, 2006, the Company has adopted the consensus of Emerging Issues Task Force ("EITF") Issue No. 04-06, "Accounting for Stripping Costs Incurred During Production in the Mining Industry." Stripping costs are those costs incurred for the removal of waste materials for the purpose of accessing ore body that will be produced commercially. Stripping costs incurred during the production phase of a mine are variable costs that are included in the costs of inventory produced during the period that the stripping costs are incurred.

Accounting for Stock-Based Compensation

As further discussed in Note 3 to the condensed consolidated financial statements, effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS No. 123R, "Share-Based Payment," using the modified prospective method. Under this transition method, stock-based compensation expense was recognized in the consolidated financial statements for stock options granted on and subsequent to January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of SFAS No. 123R, and the estimated expense for the portion vesting in the period for options granted prior to, but not vested as of January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123. As provided under the modified prospective method, results for prior periods have not been restated. Prior to its adoption of SFAS No. 123R, the Company accounted for stock-based compensation using the intrinsic value method in APB Opinion No. 25 and recognized no compensation expense in its financial statements. As permitted by SFAS No. 123, "Accounting for Stock-Based Compensation," stock-based compensation was included as a pro-forma disclosure in the notes to the consolidated financial statements.

Note 3. Stock-Based Compensation

The Company has a 2001 Stock Award and Incentive Plan (the "2001 Plan"), which provides for grants of incentive and non-qualified stock options, restricted stock, stock appreciation rights, stock awards or performance unit awards. The Plan is administered by the Compensation Committee of the Board of Directors. Stock options granted under the Plan generally have a ten year term. The exercise price for stock options are at prices at or above the fair market value of the common stock on the date of the grant, and each award of stock options will vest ratably over a specified period, generally three years.

Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS No. 123R, "Share-Based Payments," using the modified prospective method. Under this transition method, stock-based compensation expense was recognized in the consolidated financial statements for stock options granted on and subsequent to January 1, 2006 based on the grant date fair value estimated in accordance with the provisions of SFAS No. 123R, and the estimated expense for the portion vesting in the period for options granted prior to, but not vested as of January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123. As provided under the modified prospective method, results for prior periods have not been restated. The cumulative effect of the adoption of SFAS No. 123R did not have a significant impact on the financial statements.

Net income for the three months ended April 2, 2006, includes $0.5 million in pretax of compensation costs related to stock option expense as a component of marketing and administrative expenses. The related tax benefit on the non-qualified stock options is $0.1 million.

Prior to the adoption of SFAS No. 123R, all income tax benefits resulting from the exercise of stock options were presented as operating cash inflows in the consolidated statements of cash flows. As required under SFAS No. 123, the benefits of tax deductions in excess of the compensation costs recognized for those options are classified as financing inflows on the consolidated statement of cash flows.

Disclosures for the period ended April 2, 2006 are not presented because the amounts are recognized in the consolidated financial statements.

Stock Options

The fair value of options granted is estimated on the date of grant using the Black-Scholes valuation model. Compensation expense is recognized only for those options expected to vest, with forfeitures estimated at the date of grant based on the Company's historical experience and future expectations. The forfeiture rate assumptions used in the first quarter of 2006 was approximately 8%.

The weighted average grant date fair value for stock options granted during the three months ended April 2, 2006 and April 3, 2005 are $20.28 and $24.37, respectively. The weighted average grant date fair value for stock options vested during the first quarter of 2006 was $21.28. The total intrinsic value of stock options exercised during the period ended April 2, 2006 was $1.0 million.

The fair value for stock awards was estimated at the date of grant using the Black-Scholes option valuation model with the following weighted average assumptions for the three months ended:

	April 2, 2006		April 3, 2005 (pro forma)

Expected life (years)	6.4		7
Interest rate	4.83	%	4.33	%
Volatility	24.78	%	29.35	%
Expected dividend yield	0.37	%	0.32	%

The expected term of the options represents the estimated period of time until exercise and is based on historical experience of similar awards, based upon contractual terms, vesting schedules, and expectations of future employee behavior. The expected stock-price volatility is based upon the historical volatility of the Company's stock. The interest rate is based upon the implied yield on U.S. Treasury bills with an equivalent remaining term. Estimated dividend yield is based upon historical dividends paid by the Company.

The aggregate intrinsic value above is before applicable income taxes, based on the Company's closing stock price of $58.41 as of the last business day of the period ended April 2, 2006 had all options been exercised on that date. The weighted intrinsic value of the options exercised during the first quarter was $20.75. As of April 2, 2006, total unrecognized stock-based compensation expense related to nonvested stock options was approximately $4.6 million, which is expected to be recognized over a weighted average period of approximately three years.

The Company issues new shares of common stock upon the exercise of stock options.

Nonvested stock option activity for the three months ended April 2, 2006 is as follows:

Restricted Stock

The Company has granted certain corporate officers rights to receive shares of the Company's common stock under the Company's 2001 Stock Award and Incentive Plan (the 2001 Plan). The rights will be deferred for a specified number of years of service, subject to restrictions on transfer and other conditions. Upon issuance of the

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

rights, a deferred compensation expense equivalent to the market value of the underlying shares on the date of the grant was charged to stockholders' equity and was being amortized over the estimated average deferral period of approximately five years. Under the provisions of Statement No. 123R, the recognition of unearned compensation is no longer required. Accordingly, in the first quarter of 2006, the balance of Deferred Equity Compensation was reversed into Additional Paid-in Capital on the Company's balance sheet. The Company granted 44,400 shares in the first quarter of 2006 and 34,100 shares were granted in the first quarter of 2005. The fair value was determined based on the market value of unrestricted shares. The discount for the restriction was not significant. As of April 2, 2006, there was unrecognized stock-based compensation related to restricted stock of $5.4 million which will be recognized over approximately the next four years. The compensation expense amortized with respect to all units was approximately $0.3 million and $0.2 million for the quarters ended April 2, 2006 and April 3, 2005, respectively, and is included in marketing and administrative expenses. No restricted stock awards were vested as of April 2, 2006.

The following table summarizes the restricted stock activity for the Plan:

Note 6. Goodwill and Other Intangible Assets

The Company accounts for goodwill and other intangible assets in accordance with SFAS No. 142, "Goodwill and Other Intangible Assets." Under SFAS No. 142, goodwill and other intangible assets with indefinite lives are not amortized, but instead are tested for impairment at least annually in accordance with the provisions of SFAS No. 142.

The carrying amount of goodwill was $53.8 million and $53.6 million as of April 2, 2006 and December 31, 2005, respectively. The net change in goodwill since January 1, 2006 was primarily due to the effect of foreign exchange.

Acquired intangible assets subject to amortization as of April 2, 2006 and December 31, 2005 were as follows:

	April 2, 2006				December 31, 2005

(millions of dollars)		Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization

Patents and trademarks	$	6.0	$	1.5	$	6.0	$	1.4
Customer lists		2.9		0.5		2.9		0.4

	$	8.9	$	2.0	$	8.9	$	1.8

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 2010.

Included in other assets and deferred charges is an intangible asset of approximately $8.6 million which represents the non-current unamortized amount paid to a customer in connection with contract extensions at eight PCC satellite facilities. In addition, a current portion of $1.8 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 $0.5 million was amortized in the first quarter of 2006. Estimated amortization as a reduction of sales is as follows: remainder of 2006 - $1.3 million; 2007 - $1.8 million; 2008 - $1.8 million; 2009 - $1.5 million; 2010 - $1.2 million; with smaller reductions thereafter over the remaining lives of the contracts.

Note 7. Accounting for Impairment of Long-Lived Assets

The Company accounts for impairment of long-lived assets in accordance with SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." SFAS No. 144 establishes a uniform accounting model for long-lived assets to be disposed of. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, the Company estimates the undiscounted future cash flows (excluding interest), resulting from the use of the asset and its ultimate disposition. If the sum of the undiscounted cash flows (excluding interest) is less than the carrying value, the Company recognizes an impairment loss, measured as the amount by which the carrying value exceeds the fair value of the asset, determined principally using discounted cash flows. There was no charge for impairment during the first quarter of 2006.

Note 8. Accounting for Stripping Costs

Effective January 1, 2006, the Company adopted the consensus of Emerging Issues Task Force ("EITF") Issue No. 04-06, "Accounting for Stripping Costs Incurred During Production in the Mining Industry." This consensus states that stripping costs incurred during the production phase of a mine are variable production costs that should be included in the costs of inventory produced during the period that the stripping costs are incurred. The Company had previously deferred stripping costs in excess of the average life of mine stripping ratio and amortized such costs on a unit of production method when the ratio of waste to ore mined is less than the average life of mine stripping ratio. As a result, the Company recorded an after-tax charge of $ 7.1 million to its opening retained earnings and increased its opening inventory by $0.8 million. The following is a reconciliation of our opening retained earnings:

Ending retained earnings, December 31, 2005	$	828,591
Adoption of EITF 04-06, net of tax		7,119

Opening retained earnings, January 1, 2006	$	821,472

The change did not have a significant impact on the first quarter 2006 earnings.

Note 12. Accounting for Asset Retirement Obligations

SFAS No. 143, "Accounting for Asset Retirement Obligations" establishes the financial accounting and reporting obligations associated with the retirement of long-lived assets and the associated asset retirement costs. The Company has asset retirement obligations related to its PCC satellite facilities and its mining properties, both within the Specialty Minerals Segment. This statement requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. 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 2, 2006:

Note 13. Transaction with Former Parent Company

Under the terms of certain agreements entered into in connection with the Company's initial public offering in 1992, Pfizer Inc ("Pfizer") agreed to indemnify the Company against any liability arising from claims for remediation, as defined in the agreements, of on-site environmental conditions relating to activities prior to the closing of the initial public offerings. The Company had asserted to Pfizer a number of indemnification claims pursuant to those agreements during the ten-year period following the closing of the initial public offering. Since the initial public offering, the Company has incurred and expensed approximately $6 million of environmental claims under these agreements. On January 20, 2006, Pfizer and the Company agreed to settle those claims, along with certain other potential environmental liabilities of Pfizer, in consideration of a payment by Pfizer of $4.5 million. Such payment was recorded as additional paid-in-capital, net of its related tax effect.

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 2, 2006 and the related condensed consolidated statements of income and cash flows for the three-month periods ended April 2, 2006 and April 3, 2005. 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 to financial data 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 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, 2005, 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 March 2, 2006, 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, 2005 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

As discussed in the Notes to Condensed Consolidated Financial Statements, effective January 1, 2006, the Company adopted Statement of Financial Accounting Standards ("SFAS") No. 123R, "Shared-Based Payment," SFAS No. 151, "Inventory Costs - an Amendment of ARB No. 43, Chapter 4," and Emerging Issues Task Force Issue No. 04-06, "Accounting for Stripping Costs Incurred During Production in the Mining Industry."

ITEM 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

	Income and Expense Items as a Percentage of Net Sales

	Three Months Ended

	April 2, 2006		April 3, 2005

Net sales	100.0	%	100.0	%

Research and development expenses	2.7		2.9

Income from operations	7.1		9.6

Net income	4.8	%	6.1	%

Executive Summary

In the first quarter of 2006 net sales grew 6% over the prior year from $250.8 million to $266.0 million. Foreign exchange had an unfavorable impact on sales of approximately 2 percentage points of growth. Operating income decreased 21% to $19.0 million from $24.1 million in the prior year. Net income decreased 16% to $12.8 million from $15.2 million in 2005.

The comparison of our operating income and net income in the first quarter has been affected by a number of factors:

.	Unrecovered raw material and energy cost increases;
.	Paper machine and paper mill shutdowns;
.	Accelerated depreciation expense relating to the closure of two satellite PCC plants;
.	SYNSIL^® market development costs;
.	Increased bad debt expenses related to a satellite PCC customer bankruptcy;
.	Increased compensation expense relating to the adoption of SFAS No. 123R; and
.	Gain on settlement of insurance claim.

We face some significant risks and challenges in the future:

.	Our success depends in part on the performance of the industries we serve, particularly papermaking and steel making. Some of our customers may continue to face a difficult business environment, and may experience further shutdowns;
.	Consolidations in the paper and steel industries concentrate purchasing power in the hands of fewer customers, increasing pricing pressure on suppliers such as Minerals Technologies;
.	Most of our Paper PCC sales are under long-term contracts. The contracts may be terminated pursuant to their terms, or may be renewed on terms less favorable to us;
.	We are subject to cost fluctuations on magnesia and talc imported from China, including higher shipping costs and higher cost of other raw materials in both segments;
.	We are experiencing increased energy costs in both of our business segments;
.	Although the SYNSIL^® Products family has received favorable reactions from potential customers, this product line is not yet profitable and its commercial viability cannot be assured;
.	The cost of employee benefits, particularly health insurance, have risen significantly in recent years and continues to do so; and
.	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.

Despite these risks and challenges, we are optimistic about the opportunities for continued growth that are open to us, including:

.	Increasing our sales of PCC for paper by further penetration of the markets for paper filling at both free sheet and groundwood mills;
.	Increasing our sales of PCC for paper coating, particularly from the coating PCC facility in Walsum, Germany;
.	Continuing research and development activities for new products, including potential commercialization of a

	filler-fiber composite technology for the paper industry;
.	Achieving continued market acceptance of the SYNSIL^® Products family of composite minerals for the glass industry;
.	Continuing our penetration in both business segments into China, including the ramp-up of two four-unit satellite PCC plants through our joint venture with Asia Pulp & Paper (China) Pte. Ltd., and our new manufacturing facility for the Refractories segment, which is projected to commence operations in the second quarter of 2006; and
.	Increasing market penetration in the Refractories segment through high-performance products and application systems.

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

On July 19, 2005, the Company's largest customer, International Paper Company, announced a general plan to restructure certain elements of its businesses. There has been no further release of public information related to this plan that has an immediate impact on our Paper PCC product line and assets.

On March 21, 2006, we ceased operation of a one-unit satellite PCC facility in Park Falls, Wisconsin, after the paper company shut down its mill and filed for bankruptcy protection. The Company recorded a provision for bad debt of approximately $1 million in the first quarter of 2006 in connection with this bankruptcy. The paper company is presently seeking a buyer for its mill and, if successful, the Company believes it would continue to supply PCC from its satellite facility. If the Company does not resume production from its satellite facility, we could incur an impairment charge of approximately $0.6 million.

Net Sales		$	266.0	100.0	%	6	%	$	250.8	100.0	%

Worldwide net sales in the first quarter of 2006 increased 6% from the previous year to $266.0 million. Foreign exchange had an unfavorable impact on sales of approximately $5.8 million or 2 percentage points of growth. Improved demand across most product lines was achieved. Sales in the Specialty Minerals segment, which includes the PCC and Processed Minerals product lines, increased 7% to $182.4 million compared with $169.8 million for the same period in 2005. Sales in the Refractories segment grew 3% over the previous year to $83.6 million. Most of the sales increases in both segments were attributable to higher volumes.

Worldwide net sales of PCC, which is primarily used in the manufacturing process of the paper industry, increased 7% in the first quarter to $143.2 million from $134.0 million in the prior year. Foreign exchange had an unfavorable impact on sales of approximately 2 percentage points of growth. Paper PCC sales grew 7% to $128.2 million in the first quarter of 2006 from $119.7 million in the prior year. Paper PCC achieved strong sales growth in all regions as total worldwide unit volumes grew 7%. Four percentage points of this growth were attributable to the ramp-up of volumes from our new facilities in China and Germany. Sales of Specialty PCC grew 5% to $15.0 million from $14.3 million in 2005 due to increased sales from our Brookhaven, Mississippi facility.

Net sales of Processed Minerals products increased 9% in the first quarter to $39.2 million from $35.8 million in the first quarter of 2005. Talc sales increased 6% to $14.8 million from $14.0 million in the prior year due to strong global demand for plastics and automotive ceramics. Other Processed Minerals products increased 12% to $24.4 million from $21.8 million in the prior year due to strong demand from the residential and commercial constructions industries and the ramp-up of SYNSIL^®products.

Net sales in the Refractories segment in the first quarter of 2006 increased 3% to $83.6 million from $81.0 million in the prior year. Foreign currency had an unfavorable impact on sales of approximately 3 percentage points of growth. This segment continues to experience strong sales growth in the metallurgical wire product line. Sales of refractory products and systems to steel and other industrial applications decreased 5 percent to $61.1 million from $64.4 million. Sales of metallurgical products within the Refractories segment increased 36 percent to $22.5 million as compared with $16.6 million in the same period last year. This increase was attributable to the continued strong volume demand worldwide for these products.

Net sales in the United States grew 9% to $161.8 million in the first quarter of 2006. Strong volumes in the U.S. were attained in all product lines. International sales in the first quarter of 2006 increased 2% to $104.2 million.

Operating Costs and Expenses (millions of dollars)		First Quarter 2006		First Quarter 2005	Growth

Cost of goods sold	$	212.2	$	193.0	10	%
Marketing and administrative	$	27.7	$	26.6	4	%
Research and development	$	7.3	$	7.2	1	%

Cost of goods sold was 79.8% of sales compared with 76.9% of sales in the prior year. In the Specialty Minerals segment, production margin declined 10% as compared with 7% sales growth. This segment has been affected by unrecovered raw material and energy costs increases, paper machine and paper mill shutdowns, and market development costs associated with our SYNSIL^® product line. Collectively, these factors had an adverse impact of approximately $5 million on production margin and operating income. In the Refractories segment, production margin declined 2% as compared with the 3% sales growth.

Marketing and administrative costs increased 4% in the first quarter to $27.7 million and represented 10.4% of net sales. This was primarily due to increased bad debt expense relating to a customer bankruptcy and increased stock option expense of approximately $0.5 million relating to the adoption of SFAS No. 123R.

Research and development expenses increased 1% to $7.3 million and represented 2.7% of net sales as compared with 2.9% of net sales in the prior year.

Income from Operations (millions of dollars)		First Quarter 2006		First Quarter 2005	Growth

Income from operations	$	19.0	$	24.1	(21)	%

Income from operations in the first quarter of 2006 declined 21% to $19.0 million from $24.1 million in the first quarter of 2005. Income from operations represented 7.1% of net sales in the first quarter of 2006 compared with 9.6% in the first quarter of 2005.

Income from operations for the Specialty Minerals segment declined 25% to $12.2 million and was 6.7% of its net sales. Operating income for this segment was impacted by the aforementioned higher raw material and energy costs increases and paper machine and paper mill shutdowns. Operating income for the Refractories segment declined 13% to $6.7 million and was 8.0% of its net sales as compared with 9.5% of its net sales in 2005. The decline in the operating income ratio was due to a less favorable product mix and additional costs related to new business development activities. In addition, lower sales of refractory products and equipment systems in Europe and Latin America compared with a strong prior year in both regions, and the adverse effects of currencies also contributed to the shortfall.

Non-operating income (deductions), net	$	0.7	$	(1.2	)	*	%

* Percentage not meaningful

The increase in non-operating income was due primarily to an insurance settlement gain of approximately $1.8 million for property damage sustained at one of the Company's facilities.

Provision for Taxes on Income		First Quarter		First Quarter
(millions of dollars)		2006		2005	Growth

Provision for taxes on income	$	6.0	$	7.1	(15)	%

The effective tax rate decreased to 30.3% in the first quarter of 2006 from 31.2% in the prior year due to a change in the mix of earnings and an expected lower level of repatriation of foreign earnings in the current year.

Net Income		First Quarter		First Quarter
(millions of dollars)		2006		2005	Growth

Net income	$	12.8	$	15.2	(16)	%

Net income decreased 16% in the first quarter of 2006 to $12.8 million. Earnings per common share, on a diluted basis, decreased 12% to $0.64 in the first quarter of 2006 as compared with $0.73 in the prior year.

Liquidity and Capital Resources

Cash flows in the first three months of 2006 provided from operations were applied principally to fund capital expenditures, repay debt and repurchase common shares for treasury. Cash provided from operating activities amounted to $39.1 million in the first three months of 2006 as compared with $4.6 million for the same period last year. The increase in cash provided from operations was due to an improvement in working capital when compared with the prior year.

We expect to utilize our cash to support the aforementioned growth strategies.

On October 23, 2003, our Board of Directors authorized our Management Committee, at its discretion, to repurchase up to $75 million in shares over the next three-year period. As of April 2, 2006, we repurchased 1,233,100 shares of our common stock under this program at an average price of approximately $58.36 per share.

On January 26, 2006, the Company's Board of Directors authorized the Company's Management Committee, at its discretion, to repurchase up to $75 million in additional shares over the next three-year period. As of April 2, 2006, there were no shares repurchased under this program.

On January 26, 2006, our Board of Directors declared a regular quarterly dividend on our common stock of $0.05 per share. No dividends will be payable unless declared by the Board and unless funds are legally available for payment thereof.

We have $158 million in uncommitted short-term bank credit lines, of which approximately $43 million was in use at April 2, 2006. We anticipate that capital expenditures for all of 2006 will approximate $100 million. We expect to meet our 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: 2006 - $53.7 million; 2007 - $1.9 million; 2008 - $6.8 million; 2009 - $4.4 million; 2010 - $4.6 million; thereafter - $22.6 million.

Words such as "expects," "plans," "anticipates," and words and terms of similar substance, used in connection with any discussion of future operating or financial performance identify these forward-looking statements.

Although we believe we have been prudent in our plans and assumptions, we cannot guarantee that the outcomes suggested in any forward-looking statement will be realized. Achievement of future results is subject to risks, uncertainties and inaccurate assumptions. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could vary materially from those anticipated, estimated or projected. Investors should bear this in mind as they consider forward-looking statements and should refer to the discussion of certain risks, uncertainties and assumptions entitled "Cautionary Factors That May Affect Future Results" in Exhibit 99 to this Quarterly Report.

Recently Issued Accounting Standards

There are no recently issued Accounting Standards that will impact the Company.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities.

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, 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.

Property, Plant and Equipment

Property, plant and equipment are depreciated over their useful lives. Useful lives are based on management's estimates of the period that the assets can generate revenue, which does not necessarily coincide with the remaining term of a customer's contractual obligation to purchase products made using those assets. The Company's sales of PCC are predominantly pursuant to long-term evergreen contracts, initially ten years in length, with paper mills where the Company operates satellite PCC plants. The terms of many of these agreements have been extended, often in connection with an expansion of the satellite PCC plant. The Company also continues to supply PCC at one location at which the PCC contract has expired and one location, representing one unit of PCC production where the host mill has provided notice to the Company of its plans to cancel the PCC supply contract upon its expiration in

2006. Failure of a PCC customer to renew an agreement or continue to purchase PCC from the Company facility could result in an impairment of assets charge or accelerated depreciation at such facility.

Accounting for Stock-Based Compensation

Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS No. 123R, using the modified prospective method. Under this transition method, stock-based compensation expense was recognized in the consolidated financial statements for stock options granted on and subsequent to January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of SFAS No. 123R, and the estimated expense for the portion vesting in the period for options granted prior to, but not vested as of January 1, 2006, based on the grant date fair value estimated accordance with the original provisions of SFAS No. 123. As provided under the modified prospective method, results for prior periods have not been restated.

The Company used the Black-Scholes option pricing model to determine the fair value to stock options on their date of grant. This model is based upon assumptions relating to the volatility of the stock-price, the life of the option, risk-free interest rate and dividend yield. Of these, stock price volatility and option life require greater levels of judgment and are therefore critical accounting estimates.

We used a stock-price volatility assumption based upon the historical implied volatility of the Company's stock. We feel this is a good indicator of future, actual and implied volatilities. For stock options granted in the three-month period ended April 2, 2006, the Company used a volatility of 24.78%.

The expected life calculation was based upon the observed and expected time to post-vesting forfeiture and exercise. For stock options granted in the three-month period ended April 2, 2006, the Company used a 6.4 year life.

The Company believes the above critical estimates are based upon outcomes most likely to occur, however, were we to simultaneously increase or decrease the option life by one year and the volatility by 100 basis points, recognized compensation expense would change approximately $0.1 million in either direction for the three-month period ended April 2, 2006.

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 40% 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 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 $2.2 million of foreign currencies as of April 2, 2006. These

contracts mature between April and June of 2006. The fair value of these instruments at April 2, 2006 was a liability of $0.2 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 are effective in timely alerting them to material information relating to the Company (including its consolidated subsidiaries) required to be included in the Company's periodic filings with the Securities and Exchange Commission.

Changes in Internal Control Over Financial Reporting

The Company is in the process of implementing a global enterprise resource planning ("ERP") system to manage its business operations. As of April 2, 2006, all of our domestic locations were using the new system. The worldwide implementation is expected to be completed over the next few years and involves changes in systems that include internal controls. Although the transition has proceeded to date without material adverse effects, the possibility exists that our migration to the new ERP system could adversely affect the Company's internal controls over financial reporting and procedures. We are reviewing each system as it is being implemented and the controls affected by the implementation of the new systems, and are making appropriate changes to affected internal controls as we implement the new systems. We believe that the controls as modified are appropriate and functioning effectively.

There was no change in the Company's internal control over financial reporting (other than the ongoing implementation of the ERP system discussed above) during the quarter ended April 2, 2006 that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.
