PART I

Item 1. Business

Minerals Technologies Inc. (the "Company") is a resource- and technology-based company that develops, produces and markets worldwide a broad range of specialty mineral, mineral-based and synthetic mineral products and supporting systems and services. The Company has two reportable segments: Specialty Minerals and Refractories. The Specialty Minerals segment produces and sells the synthetic mineral product precipitated calcium carbonate ("PCC") and processed mineral product quicklime ("lime"), and mines mineral ores then processes and sells natural mineral products, primarily limestone and talc. This segment's products are used principally in the paper, building materials, paint and coatings, glass, ceramic, polymer, food, automotive and pharmaceutical industries. The Refractories segment produces and markets monolithic and shaped refractory materials and specialty products, services and application and measurement equipment, and calcium metal and metallurgical wire products. Refractories segment products are primarily used in high-temperature applications in the steel, non-ferrous metal and glass industries.

The Company maintains a research and development focus. The Company's research and development capability for developing and introducing technologically advanced new products has enabled the Company to anticipate and satisfy changing customer requirements, creating market opportunities through new product development and product application innovations.

Specialty Minerals Segment

PCC Products and Markets

The Company's PCC product line net sales were $602.6 million, $557.0 million and $516.3 million for the years ended December 31, 2007, 2006 and 2005, respectively. The Company's sales of PCC have been, and are expected to continue to be, made primarily to the printing and writing papers segment of the paper industry. The Company also produces PCC for sale to companies in the polymer, food and pharmaceutical industries. See Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations."

PCC Products - Paper

In the paper industry, the Company's PCC is used:

•	As a filler in the production of coated and uncoated wood-free printing and writing papers, such as office papers;
•	As a filler for coated and uncoated groundwood (wood-containing) paper such as magazine and catalog papers; and
•	As a coating pigment for both wood-free and groundwood papers.

The Company's Paper PCC product line net sales were $542.0 million, $500.6 million and $460.7 million for the years ended December 31, 2007, 2006 and 2005, respectively.

Approximately 45% of the Company's sales consists of PCC sold to papermakers at "satellite" PCC plants. A satellite PCC plant is a PCC manufacturing facility located at a paper mill, thereby eliminating costs of transporting PCC from remote production sites to the paper mill. The Company believes the competitive advantages offered by improved economics and superior optical characteristics of paper produced with PCC manufactured by the Company's satellite PCC plants resulted in substantial growth in the number of the Company's satellite PCC plants since the first such plant was built in 1986. For information with respect to the locations of the Company's PCC plants at December 31, 2007, see Item 2, "Properties," below.

The Company currently manufactures several customized PCC product forms using proprietary processes. Each product form is designed to provide optimum balance of paper properties including brightness, opacity, bulk, strength and improved printability. The Company's research and development and technical service staffs focus on expanding sales from its existing satellite PCC plants as well as developing new technologies for new applications. These technologies include, among others, acid-tolerant ("AT^®") PCC, which allows PCC to be introduced to the large wood-containing segment of the printing and writing paper market, and OPACARB^® PCC, a family of products for paper coating.

The Company owns, staffs, operates and maintains all of its PCC facilities, and owns or licenses the related technology. Generally, the Company and its paper mill customers enter into long-term evergreen agreements, initially ten years in length, pursuant to which the Company supplies substantially all of the customer's precipitated calcium carbonate filler requirements.

The Company is generally permitted to sell to third-parties PCC produced at a satellite plant in excess of the host paper mill's requirement.

The Company also sells a range of PCC products to paper manufacturers from production sites not associated with paper mills from merchant facilities at Adams, Massachusetts; Lifford, England; and Walsum, Germany.

PCC Markets - Paper

Uncoated Wood-Free Printing and Writing Papers - North America. Beginning in the mid-1980's, as a result of a concentrated research and development effort, the Company's satellite PCC plants facilitated the conversion of a substantial percentage of North American uncoated wood-free printing and writing paper producers to lower-cost alkaline papermaking technology. The Company estimates that during 2007, more than 90% of North American uncoated wood-free paper was produced employing alkaline technology. Presently, the Company owns and operates 20 commercial satellite PCC plants located at paper mills that produce uncoated wood-free printing and writing papers in North America.

Uncoated Wood-Free Printing and Writing Papers - Outside North America. The Company estimates the amount of uncoated wood-free printing and writing papers produced outside of North America at facilities that can be served by satellite and merchant PCC plants is more than twice as large (measured in tons of paper produced) as the North American uncoated wood-free paper market currently served by the Company. The Company believes that the superior brightness, opacity and bulking characteristics offered by its PCC products allow it to compete with suppliers of ground limestone and other filler products outside of North America. Presently, the Company owns and operates 24 commercial satellite PCC plants located at paper mills that produce uncoated wood-free printing and writing papers outside of North America.

Uncoated Groundwood Paper. The uncoated groundwood paper market, including newsprint, represents approximately 35% of worldwide paper production. Paper mills producing wood-containing paper still generally employ acid papermaking technology. The conversion to alkaline technology by these mills has been hampered by the tendency of wood-containing papers to darken in an alkaline environment. In an attempt to introduce PCC to the wood-containing segments of the paper industry, the Company has developed and patented a system for the manufacture of high-quality groundwood paper in an acidic environment using PCC (AT^® PCC). Furthermore, as groundwood or wood-containing paper mills use larger quantities of recycled fiber, there is a trend toward the use of neutral papermaking technology in this segment for which the Company presently supplies traditional PCC chemistries. The Company now supplies PCC to approximately 29 paper machines at about 15 groundwood paper mills around the world and licenses its technology to a ground calcium carbonate producer to help accelerate the conversion from acid to alkaline papermaking.

Coated Paper. The Company is also placing emphasis on the use of PCC to coat paper, and expects that its research and development in coating pigment technology will open up a large market for PCC that will build slowly as more paper companies include PCC in their proprietary coating formulations. PCC may be used to increase gloss, opacity, brightness and printability of the paper or to reduce costs while maintaining comparable quality. The coated paper market is large, and the Company believes this market will continue to grow at a higher average growth rate than the uncoated paper market and therefore provides a substantial market opportunity for the Company. PCC coating products are produced at 10 of the Company's PCC plants worldwide.

Specialty PCC Products and Markets

The Company also produces and sells a full range of dry PCC products on a merchant basis for non-paper applications. The Company's Specialty PCC product line net sales were $60.6 million, $56.4 million and $55.6 million for the years ended December 31, 2007, 2006 and 2005, respectively. The Company sells surface-treated and untreated grades of PCC to the polymer industry for use in automotive and construction applications, and to the adhesives and printing inks industries. The Company's PCC is also used by the food and pharmaceutical industries as a source of bio-available calcium in tablets and foodstuffs, as a buffering agent in tablets, and as a mild abrasive in toothpaste. The Company produces PCC for specialty applications from production sites at Adams, Massachusetts; and Lifford, England.

Processed Minerals - Products and Markets

The Company mines and processes natural mineral products, primarily limestone and talc. The Company also manufactures lime, a limestone-based product. The Company's net sales of processed mineral products were $114.0 million, $118.6 million and $112.7 million for the years ended December 31, 2007, 2006 and 2005, respectively. Net sales of talc products were $37.3 million, $38.9 million and $35.5 million for the years ended December 31, 2007, 2006 and 2005, respectively. Net sales of ground calcium carbonate ("GCC") products, which are principally lime and limestone, were $76.7 million, $79.7 million and $77.2 million for the years ended December 31, 2007, 2006 and 2005, respectively. See Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations."

Lime produced at the Company's Adams, Massachusetts, and Lifford, United Kingdom, facilities is used primarily as a raw material for the manufacture of PCC at these sites and at some satellite PCC plants, and is sold commercially to various chemical and other industries.

The Company mines, beneficiates and processes talc at its Barretts site, located near Dillon, Montana. Talc is sold worldwide in finely ground form for ceramic applications and in North America for paint and coatings and polymer applications. Because of the exceptional chemical purity of the Barretts ore, a significant portion of worldwide automotive catalytic converter ceramic substrates contain the Company's Barretts talc.

The Company's natural mineral products are supported by the Company's limestone reserves located in the western and eastern parts of the United States, and talc reserves located in Montana. The Company estimates these reserves, at current usage levels, to be in excess of 30 years at its limestone production facilities and in excess of 20 years at its talc production facility.

Refractories Segment

Refractory Products and Markets

Refractories Products

The Company offers a broad range of monolithic and pre-cast refractory products and related systems and services. The Company's Refractory segment net sales were $361.1 million, $347.9 million and $327.8 million for the years ended December 31, 2007, 2006 and 2005, respectively. See Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations."

Refractory product sales are often supported by Company-supplied proprietary application equipment and on-site technical service support. The Company's proprietary application equipment is used to apply refractory materials to the walls of steel-making furnaces and other high temperature vessels to maintain and extend their lives. Net sales of refractory products, including those for non-ferrous applications, were $290.5 million, $264.6 million and $239.3 million for the years ended December 31, 2007, 2006 and 2005. The Company's proprietary SCANTROL™ application system, and other robotic application equipment systems such as its MINSCAN™ system, allow for remote-controlled application of the Company's refractory products in steel-making furnaces, as well as in steel ladles and blast furnaces. Since the steel-making industry is characterized by intense price competition, which results in a continuing emphasis on increased productivity, the SCANTROL™ application system, the MINSCAN™ system, and the technologically advanced refractory materials developed in the Company's research laboratories have been well accepted by the Company's customers. These products allow steel makers to improve their performance through, among other things, the application of monolithic refractories to furnace linings while the furnace is at operating temperature, thereby eliminating the need for furnace cool-down periods and steel-production interruption. The result is a lower overall cost for steel produced by steel makers.

The Company's experienced technical service staff and advanced application equipment provide customers assurance that they will achieve their desired productivity objectives. The Company's technicians are also able to conduct laser measurement of refractory wear, sometimes in conjunction with robotic application tools, to improve refractory performance at many customer locations. The Company believes that these services, together with its refractory product offerings, provide it with a strategic marketing advantage.

Over the past several years the Refractories segment has continued to increase its growth due to its ability to reformulate its products and application technology to maintain its competitive advantage in the market place. Some of the new products the Company has introduced in the past few years include:

•	HOTCRETE™, high durability shotcrete products that can be applied hot through customized equipment;
•	LACAM^® laser-based refractory measurement systems; and
•	SCANTROL™, a fully integrated application system combining the LACAM^® and MINSCAN™ technologies.

The Company has also expanded its refractories business through selective acquisitions over the past several years. In 2000, the Company acquired Ferrotron Elektronik GmbH, a manufacturer of advanced laser scanning devices, sensors and other measuring equipment designed for the steel industry. In 2001, the Company acquired the refractories business of Martin Marietta Magnesia Specialties Inc. and purchased Rijnstaal B.V., a Netherlands-based producer of cored metal wire products used mainly in the steel and foundry industries. These acquisitions have increased both the breadth of the product lines and markets served by the Refractories segment. In 2002, the Company acquired VisionTech a Finland-based company that

develops and manufactures a refractory lining measuring system. In 2003, the Company acquired the assets of ISA Manufacturing, Inc., a U.S.-based company that develops and manufactures pre-cast refractory shapes. In 2005, the Company acquired the metallurgical measurement technology/digital electrode control system product line of ET Electrotechnology GmbH. This technology offers a system that maintains steady state conditions and optimizes power consumption in electric steel making and ladle furnaces. In October 2006, the Company acquired ASMAS, an Istanbul-based Turkish producer of refractories to increase its ability to service the growing steel industries in Eastern Europe and the Middle East.

Refractories Markets

The principal market for the Company's refractory products is the steel industry. Management believes that certain trends in the steel industry will continue to provide growth opportunities for the Company. These trends include rapid growth and quality improvements in select geographic regions (e.g., China, Eastern Europe and India) the development of improved manufacturing processes such as thin-slab casting, the trend in North America to shift production from integrated mills to electric arc furnaces (mini-mills) and the ever-increasing need for improved productivity and longer lasting refractories.

The Company sells its refractory products in the following markets:

Steel Furnace. The Company sells gunnable monolithic refractory products and application systems to users of basic oxygen furnaces and electric furnaces for application on furnace walls to prolong the life of furnace linings.

Other Iron and Steel. The Company sells monolithic refractory materials and pre-cast refractory shapes for iron and steel ladles, vacuum degassers, continuous casting tundishes, blast furnaces and reheating furnaces. The Company offers a full line of materials to satisfy most continuous casting refractory applications. This full line consists of gunnable materials, refractory shapes and permanent linings.

Industrial Refractory Systems. The Company sells refractory shapes and linings to non-steel refractories consuming industries including glass, cement, aluminum and petrochemicals, power generation and other non-steel industries. The Company also produces a specialized line of carbon composites and pyrolitic graphite primarily sold under the PYROID^® trademark, primarily to the aerospace and electronics industries.

Metallurgical Products and Markets

The Company produces a number of other technologically advanced products for the steel industry, including calcium metal, metallurgical wire products and a number of metal treatment specialty products. Net sales of metallurgical products were $70.6 million, $83.3 million and $88.5 million for the years ended December 31, 2007, 2006 and 2005. The Company manufactures calcium metal at its Canaan, Connecticut, facility and purchases calcium in international markets. Calcium metal is used in the manufacture of the Company's PFERROCAL^® solid-core calcium wire, and is also sold for use in the manufacture of batteries and magnets. The Company sells metallurgical wire products and associated wire-injection equipment for use in the production of high-quality steel. These metallurgical wire products are injected into molten steel to improve castability and reduce imperfections. The steel produced is used for high-pressure pipeline and other premium-grade steel applications.

Marketing and Sales

The Company relies principally on its worldwide direct sales force to market its products. The direct sales force is augmented by technical service teams that are familiar with the industries to which the Company markets its products, and by several regional distributors. The Company's sales force works closely with the Company's technical service staff to solve technical and other issues faced by the Company's customers. The Company's technical service staff assists paper producers in ongoing evaluations of the use of PCC for paper coating and filling applications. In the Refractory segment, the Company's technical service personnel advise on the use of refractory materials, and, in many cases pursuant to service agreements, apply the refractory materials to the customers' furnaces and other vessels. Continued use of skilled technical service teams is an important component of the Company's business strategy.

The Company works closely with its customers to ensure that their requirements are satisfied, and it often trains and supports customer personnel in the use of the Company's products. The Company conducts domestic marketing and sales from Bethlehem, Pennsylvania, and from regional sales offices in the eastern and western United States. The Company's international marketing efforts are directed from regional centers located in Brussels, Belgium; Sao Jose Dos Campos, Brazil; and Shanghai, China. The Company believes its processed minerals are at regional locations that satisfy the stringent delivery requirements of the industries they serve. The Company also believes that its worldwide network of sales personnel and manufacturing sites facilitates the continued international expansion.

Raw Materials

The Company's ability to achieve anticipated results 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, magnesia and alumina for its Refractory operations, and on having adequate access to ore reserves at its mining operations.

The Company uses lime in the production of PCC and is a significant purchaser of lime worldwide. Generally, lime is purchased under long-term supply contracts from unaffiliated suppliers located in close geographic proximity to the Company's PCC plants.

The principal raw materials used in the Company's monolithic refractory products are refractory-grade magnesia and various forms of aluminasilicates. The Company also purchases calcium metal, calcium silicide, graphite, calcium carbide and various alloys for use in the production of metallurgical wire products and uses lime and aluminum in the production of calcium metal. The Company purchases a significant portion of its magnesia requirements from sources in China. High demand for bulk raw materials from China has caused price increases of some key raw materials which ultimately could affect the Company's sales to its customers. In addition, higher transportation costs have also increased the delivered cost of raw materials imported from China to North America and Europe. The Company believes that in the event of supply interruptions of its refractory raw material requirements it could obtain adequate supplies from alternate sources in China and elsewhere at reasonable costs.

Competition

The Company is continually engaged in efforts to develop new products and technologies and refine existing products and technologies in order to remain competitive and to position itself as a market leader.

With respect to its PCC products, the Company competes for sales to the paper industry with other minerals, such as GCC and kaolin, based in large part upon technological know-how, patents and processes that allow the Company to deliver PCC that it believes imparts gloss, brightness, opacity and other properties to paper on an economical basis. The Company is the leading manufacturer and supplier of PCC to the paper industry.

The Company competes in sales of its limestone and talc based primarily upon quality, price, and geographic location.

With respect to the Company's refractory products, competitive conditions vary by geographic region. Competition is based upon the performance characteristics of the product (including strength, consistency and ease of application), price, and the availability of technical support.

Research and Development

Many of the Company's product lines are technologically advanced. Our expertise in inorganic chemistry, crystallography and structural analysis, fine particle technology and other aspects of materials science apply to and support all of our product lines, the Company's business strategy for continued growth in sales and profitability depends, to a large extent, on the continued success of its research and development activities. Among the significant achievements of the Company's research and development efforts have been: the satellite PCC plant concept; PCC crystal morphologies for paper coating; the development of HOTCRETE™ and OPTISHOT™ shotcrete refractory products; LACAM^® laser-based refractory measurement systems; and the MINSCAN™ and SCANTROL™ application systems.

Going forward, the Company will continue to develop its filler-fiber composite material, which would increase filler levels in uncoated freesheet paper to upwards of 30%. This product remains in development and is now in large-scale trials with customers. The Company will also continue to reformulate its refractory materials to be more competitive, and will also continue development of unique calcium carbonates for use in novel biopolymers.

For the years ended December 31, 2007, 2006 and 2005, the Company spent approximately $26.3 million, $27.8 million and $27.0 million, respectively, on research and development. The Company's research and development spending for 2007 was approximately 2.4% of net sales.

The Company maintains its primary research facilities in Bethlehem and Easton, Pennsylvania. It also has research and development facilities in China, Finland, Germany, Ireland, Japan and Turkey. Approximately 102 employees worldwide are engaged in research and development. In addition, the Company has access to some of the world's most advanced papermaking and paper coating pilot facilities.

Patents and Trademarks

The Company owns or has the right to use approximately 397 patents and approximately 741 trademarks related to its business. The Company believes that its rights under its existing patents, patent applications and trademarks are of value to its operations, but no one patent, application or trademark is material to the conduct of the Company's business as a whole.

Insurance

The Company maintains liability and property insurance and insurance for business interruption in the event of damage to its production facilities and certain other insurance covering risks associated with its business. The Company believes such insurance is adequate for the operation of its business. There is no assurance that in the future the Company will be able to maintain the coverage currently in place or that the premiums will not increase substantially.

Employees

At December 31, 2007, the Company employed 2,706 persons, of whom 1,209 were employed outside of the United States.

Environmental, Health and Safety Matters

The Company's operations are subject to federal, state, local and foreign laws and regulations relating to the environment and health and safety. Certain of the Company's operations involve and have involved the use and release of substances that have been and are classified as toxic or hazardous within the meaning of these laws and regulations. Environmental operating permits are, or may be, required for certain of the Company's operations and such permits are subject to modification, renewal and revocation. The Company regularly monitors and reviews its operations, procedures and policies for compliance with these laws and regulations. The Company believes its operations are in substantial compliance with these laws and regulations and that there are no violations that would have a material effect on the Company. Despite these compliance efforts, some risk of environmental and other damage is inherent in the Company's operations, as it is with other companies engaged in similar businesses, and there can be no assurance that material violations will not occur in the future. The cost of compliance with these laws and regulations is not expected to have a material adverse effect on the Company. The Company obtained indemnification for certain potential environmental, health and safety liabilities under agreements entered into between the Company and Pfizer Inc ("Pfizer") or Quigley Company, Inc., a wholly-owned subsidiary of Pfizer, in connection with the initial public offering of the Company in 1992. See "Certain Relationships and Related Transactions" in Item 13.

Item 1A. Risk Factors

The disclosure and analysis set forth in this report contains certain forward-looking statements, particularly statements relating to future actions, future performance or results of current and anticipated products, sales efforts, expenditures, and financial results. From time to time, the Company also provides forward-looking statements in other publicly-released materials, both written and oral. Forward-looking statements provide current expectations and forecasts of future events such as new products, revenues and financial performance, and are not limited to describing historical or current facts. They can be identified by the use of words such as "expects," "plans," "anticipates," and other words and phrases of similar meaning.

Forward-looking statements are necessarily based on assumptions, estimates and limited information available at the time they are made. A broad variety of risks and uncertainties, both known and unknown, as well as the inaccuracy of assumptions and estimates, can affect the realization of the expectations or forecasts in these statements. Consequently, no forward-looking statement can be guaranteed. Actual future results may vary materially.

The Company undertakes no obligation to update any forward-looking statements. Investors should refer to the Company's subsequent filings under the Securities Exchange Act of 1934 for further disclosures.

As permitted by the Private Securities Litigation Reform Act of 1995, the Company is providing the following cautionary statements which identify factors that could cause the Company's actual results to differ materially from historical and expected

results. It is not possible to foresee or identify all such factors. Investors should not consider this list an exhaustive statement of all risks, uncertainties and potentially inaccurate assumptions.

•	Growth Rate
	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 Asia and Europe; increasing its penetration into product markets such as the market for paper coating 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 filler-fiber composite materials for the paper industry; and acquisitions. Difficulties, delays or failure of any of these strategies could affect the future growth rate of the Company.
•	Contract Renewals
	Generally, the Company's sales of PCC are pursuant to long-term evergreen agreements, 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 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 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.
•	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, following a string of bankruptcies, 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.
•	Litigation; Environmental Exposures
	The Company's operations are subject to international, federal, state and local governmental, tax and other laws and regulations, and potentially to claims for various legal, environmental and tax matters. The Company is currently a party in various litigation matters. While the Company carries liability insurance, which it believes to be appropriate to its businesses, and has provided reserves for such 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.
	In addition, future events, such as changes in or modifications or interpretations of existing laws and regulations, or enforcement polices, or further investigation or evaluation of the potential health hazards of certain products, may give rise to additional compliance and other costs that could have a material adverse effect on the Company.
•	New Products
	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.
•	Competition; Protection of Intellectual Property
	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.
•	Risks of Doing Business Abroad
	As the Company expands its operations overseas, it faces increased risks of doing business abroad, including inflation, fluctuation in interest rates and currency exchange 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 these areas could cause actual results to differ materially from historical and expected results.

•		Availability of Raw Materials
		The Company's ability to achieve anticipated results 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 Refractory operations and on having adequate access to ore reserves of appropriate quality at its mining operations. Unanticipated changes in the costs or availability of such raw materials, or in the Company's ability to have access to its ore reserves, could adversely affect the Company's results of operations.
•	Cyclical Nature of Customers' Businesses
	The majority of the Company's sales are to customers in two industries, paper manufacturing and steel manufacturing, which have historically been cyclical. The Company's exposure to variations in its customers' businesses has been reduced by the diversification of its portfolio of products and services; and by its geographic expansion. Also, the Company has structured some 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. In addition, our Processed Minerals and Specialty PCC product lines are impacted by the domestic building and construction markets. The residential component of this market is experiencing a significant slowdown which could adversely impact growth. However, a sustained 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.

^{1 This plant is leased to another company.²Leased by the Company. The facilities in Cork, Ireland, are
operated pursuant to a 99-year lease, the term of which commenced in 1963. The
Company's headquarters in New York, New York, are held under a lease which
expires in 2010.³This plant is owned through a joint venture.⁴These plants are held for sale and are included in discontinued
operations.

     The Company believes that its facilities, which are of
varying ages and are of different construction types, have been satisfactorily
maintained, are in good condition, are suitable for the Company's operations and
generally provide sufficient capacity to meet the Company's production
requirements. Based on past loss experience, the Company believes it is
adequately insured with respect to these assets and for liabilities which are
likely to arise from its operations.

Item 3.   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 310 pending silica
cases and 26 pending asbestos cases. To date, 1155 silica cases and 1 asbestos
case 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 in 2006 was $0.1 million. Costs for the
legal defense of these cases in 2007 were $78,500. Our experience has been that
MTI is not liable to plaintiffs in any of these lawsuits and MTI 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 ("DEP") 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 a report
characterizing the contamination. We are awaiting review and approval of
this report 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 are still conducting investigations
of potential groundwater contamination. To date, the results of
investigation indicate that there is some oil contamination of the
groundwater. We are conducting further investigations of the groundwater.

•

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 $200,000, 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 is
being undertaken pursuant to an administrative Consent Order issued by the
Massachusetts Department of Environmental Protection on June 18, 2002. The Order
required payment of a civil fine in the amount of $18,500, the investigation of
options for ensuring that the facility's wastewater treatment ponds will not
result in discharge to groundwater, and closure of a historic lime solids
disposal area. The Company informed the Massachusetts Department of
Environmental Protection of proposed improvements to the wastewater treatment
system on June 29, 2007, and is committed to implementing the improvements by
June 1, 2012. Preliminary engineering reviews indicate that the estimated cost
of these upgrades to operate this facility beyond 2012 may be between $6 million
and $8 million. The Company estimates that remediation costs would approximate
$500,000, which has been accrued as of December 31, 2007.
     The Company and its subsidiaries are not party to any
other material pending legal proceedings, other than routine litigation
incidental to their businesses.

Executive Summary

     During the third quarter of 2007, the Company completed
an in-depth strategic review of all its operations to determine the Company's
future direction, structure, business portfolios and technologies for improved
financial performance. As a result of this review, the Company realigned its
operations by exiting certain businesses, and consolidating some product lines.
As a result, the Company recorded an impairment of assets charge of $140.9
million, of which $46.8 million was reclassified to discontinued operations. In
addition, in 2007 the Company recorded restructuring and other costs of $18.3
million related to these exit activities, of which $2.3 million was reclassified
to discontinued operations. These restructuring costs were primarily related to
a workforce reduction of approximately 200 employees, or about seven percent of
the Company's global workforce. The major components of the realignment were as
follows:

Synsil^® Products

•

The Company has exited its Synsil^® Products
product line and will sell its Synsil^® Products manufacturing
facilities in Chester, South Carolina, Cleburne, Texas, and the customer
sampling facility in Woodville, Ohio. This resulted in an impairment of
assets charge of approximately $42.2 million, which is included in
discontinued operations.

•
We have concluded that Synsil®,
in its current product form, is not suitable to penetrate a significant
portion of the market previously envisioned. The initial success achieved in
certain market segments proved unsustainable at higher operating/fill rates
for major glass market segments.

Processed Minerals and Specialty PCC

•

The company will realign these product lines, which
consists of four mines and processing facilities in the United States; two
plants in the Midwest that process imported ores; and the Specialty PCC
product line.

•
The two Midwest plants in Mt.
Vernon, Indiana, and Wellsville, Ohio, acquired in 2002, which primarily
process Chinese talc ores, will be held for sale and are included in
discontinued operations. This realignment will result in a change of
direction from diversified product lines that included processing imported
ore to an integrated "mine to market" strategy. The Company recorded
impairment of assets charges of approximately $5.9 million related to the
realignment of the Processed Minerals product line, of which $4.6 million
was included in discontinued operations.

•

Going forward, four fully integrated operations will be
the focus of the "mine to market" strategy, three of which produce ground
calcium carbonate, primarily for the construction and automotive sectors.
These are in Adams, Massachusetts; Canaan, Connecticut; and Lucerne Valley,
California. The fourth facility mines and produces talc in Barretts,
Montana.

•

The company also will consolidate its Specialty PCC
operation in the United States. The majority of Specialty PCC customers
serviced from the Brookhaven, Mississippi, facility will be transferred to
the Company's Adams, Massachusetts, plant and the assets at Brookhaven will
be held for sale. This resulted in an impairment of assets charge of
approximately $12.7 million related to the closing of the Brookhaven,
Mississippi facility. The Company will continue to operate its Specialty PCC
facility in Lifford, England.

European Coating PCC

•
The company will modify the
marketing strategy for its coating PCC products and will convert from a
merchant business model to a satellite business model for coating PCC, one
that has proven successful in the past. This has resulted in consolidation
of the coating PCC operations in Europe with the closure of our PCC merchant
facility in Hermalle, Belgium.

•

Current commercial customers have been transferred to our
coating PCC merchant facility in Walsum, Germany, which will also focus on
supporting market development activities for the satellite PCC program. The
Company recorded an impairment of assets charge related to the coating
development program of approximately $58.7 million.

Refractories Segment

•

Due to slower than anticipated rate of market
penetration, the Company has adjusted its strategy for its refractories
business in China. The Company will continue to develop new business there
but will modify the infrastructure to support a more focused marketing
effort. The Company recorded an impairment of assets charge in this segment
of approximately $14.8 million.

Additional Impairments

•

The Pensacola, Florida facility will be dismantled after
final customer commitments have been met in 2008. This resulted in an
impairment of assets charge of $3.7 million. Additional impairment of assets
charges of $2.9 million were also included in the Paper PCC product line.

     As a result of the aforementioned impairment and
restructuring charges, the Company recorded a loss from continuing operations of
$25.7 million or $1.34 per share and a loss from discontinued operations of
$37.8 million or $1.97 per share.

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

•

Increasing our sales of PCC for paper by further
penetration of the markets for paper filling at both freesheet and
groundwood mills;

•

Development of the filler-fiber composite program, to
increase the fill-rate for uncoated freesheet paper, which continues to
undergo large-scale paper machine trials.

•

Further development of the Company's PCC products,
filling and coating, for use in the satellite model.

•

Development of unique calcium carbonates used in the
manufacture of novel biopolymers, an emerging market opportunity.

•

Rapid deployment of value-added formulations of
refractory materials that not only reduce costs but improve performance.

•

Leverage the Company's expertise in crystal engineering,
especially in helping papermakers customize PCC morphologies for specific
paper applications.

•

Continuing our penetration in emerging markets through
our manufacturing facility in China and our recent acquisition in Turkey,
both within the Refractories segment.

•

Further increasing market penetration in the Refractories
segment through development of high-performance products and equipment
systems.

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

16

•

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 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;

•

Our filler-fiber composite technology continues in
development through customer trials, but has yet to be proven on a long-term
commercial scale.

•

We are subject to cost fluctuations on raw materials,
including shipping costs, particularly for magnesia and alumina imported
from China;

•

Our Processed Minerals and Specialty PCC product lines
are highly influenced by the domestic building and construction markets.

•

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.

     Worldwide net sales in 2007 increased 5% from the
previous year to $1.078 billion. Foreign exchange had a favorable impact on
sales of $31.4 million or 3 percentage points of growth. Sales in the Specialty
Minerals segment, which includes the PCC and Processed Minerals product lines,
increased 6% to $716.6 million compared with $675.6 million for the same period
in 2006. Sales in the Refractories segment grew 4% over the previous year to
$361.1 million. In 2006, worldwide net sales increased 7% to $1.024 billion from
$956.8 million in the prior year. Specialty Minerals segment sales increased
approximately 7% and Refractories segment sales increased approximately 6% in
2006.
     Worldwide net sales of PCC, which is primarily used in
the manufacturing process of the paper industry, increased 8% to $602.6 million
from $557.0 million in the prior year. Foreign exchange had a favorable impact
on sales of approximately $19.5 million or 4 percentage points of growth.
Worldwide net sales of Paper PCC increased 8% to $542.0 million from $500.6
million in the prior year. Sales growth was attributable to increased selling
prices from the pass-through to customers of raw material cost increases and to
foreign currency. Paper PCC sales volume decreased slightly from the prior year.
Increased PCC volumes at several facilities were more than offset by paper
industry consolidations, primarily in North America. Sales of Specialty PCC grew
7% to $60.6 million from $56.4 million in 2006. This increase was primarily
attributable to improved volumes, particularly in Europe, and to the favorable
effects of foreign currency.
     Worldwide net sales of PCC increased 8% in 2006 to
$557.0 million from $516.3 million in the prior year. Net sales of Paper PCC
increased 9% to $500.6 million while Paper PCC volumes grew 5%. In 2006, sales
growth was achieved in all regions, with the largest growth occurring in Asia
due to the ramp up of two new satellite plants in China. Sales of Specialty PCC
grew 1% in 2006 to $56.4 million from $55.6 million in the prior year.

17

     Net sales of Processed Minerals products in 2007
decreased 4% to $114.0 million from $118.6 million in 2006. GCC products and
talc products both decreased 4% in 2007 to $76.7 million and $37.3 million,
respectively. The decrease in the Processed Minerals product line was primarily
attributable to weakness in the domestic residential construction industry and
the automotive market.
     Net sales of Processed Minerals products in 2006
increased 5% to $118.6 million from $112.7 million in 2005. This increase was
primarily attributable to strong global demand in plastics and healthcare
related markets within the talc product line.
     Net sales in the Refractories segment in 2007 increased
4% to $361.1 million from $347.9 million in the prior year. Foreign exchange had
a favorable impact on sales of $11.9 million or 3 percentage points of sales
growth. Sales from the Turkish acquisition made in late 2006 contributed an
additional 4 percentage points of growth in 2007. Sales of refractory products
and systems to steel and other industrial applications increased 10% to $290.5
million in 2007 from $264.6 million in the prior year. This growth was due to
foreign currency and the Turkish acquisition. Sales of metallurgical products
within the Refractories segment decreased 15% to $70.6 million from $83.3
million in 2006. This decrease was due to lower volumes in all regions of the
world, and lower prices resulting from the reduction in the cost of raw
materials for this product that is traditionally passed through to the
customers.
     Net sales in the Refractories segment in 2006 increased
6% to $347.9 million from $327.8 million in the prior year. Sales of refractory
products and systems increased 11% to $264.6 million in 2006 from $239.3 million
in the prior year. This growth was attributable to increased volume in North
America and Europe. Sales of metallurgical products decreased 6% in 2006 to
$83.3 million from $88.5 million in the prior year. This decline was due to
lower selling prices as raw material cost reductions were passed on to
customers.
     Net sales in the United States decreased approximately
2% to $581.9 million in 2007 and represented approximately 54% of consolidated
net sales. International sales increased approximately 15% to $495.8 million,
due primarily to foreign currency and the acquisition in Turkey.

     Cost of goods sold in 2007 was 78.4% of sales compared
with 78.1% in the prior year. Our cost of goods sold grew 6% which had an
unfavorable leveraging impact on our 5% sales growth resulting in a 3% increase
in production margin. This unfavorable leveraging occurred in both segments. In
the Specialty Minerals segment, the production margin increased 5% as compared
with 6% sales growth. This segment has been affected by reduced demand in the
Processed Minerals product line and paper machine and paper mill shutdowns which
were partially offset by the recovery of raw material costs and the benefit of
foreign currency. In the Refractories segment, the production margin increased
1% as compared with 4% sales growth. This segment has been affected by lower
margins in the metallurgical product line.
     Cost of goods sold in 2006 was 78.1% of sales compared
with 77.8% of sales in 2005. Production margin grew 6% as compared with 7% sales
growth. This unfavorable leveraging occurred in the Specialty Minerals segment
where production margins increased 2% as compared with 7% sales growth. During
2006, margins in this segment were affected by unrecovered lime cost increases
and paper machine and paper mill shutdowns in the PCC product line, and
unrecovered energy cost increases in the Processed Minerals product line. These
negative factors largely offset the improvements from the ramp-up of our two new
satellite PCC facilities in China, increased demand for PCC, particularly in
North America and Europe, and cost reduction initiatives.
     In the Refractories segment, production margin increased
12% in 2006 over the prior year compared with 6% sales growth. This was
primarily due to improved steel industry conditions in 2006 and cost reduction
initiatives through the reformulation of refractory products and strong demand
for high value products.
     Marketing and administrative costs were $104.6 million
in 2007, the same as the prior year and represented 9.7% of net sales as
compared with 10.2% in the prior year. In 2006, marketing and administrative
expenses increased 7% to $104.6 million from 98.1 million in 2005. This increase
was primarily attributable to increased worldwide infrastructure costs and other
employee benefits, including increased stock option expense of $2.3 million
relating to the adoption of SFAS No. 123 (R).

18

     Research and development expenses decreased 5% in 2007
to $26.3 million and represented 2.4% of net sales. This decrease was a result
of the timing of lower trial activity, primarily in the Paper PCC product line.
In 2006, research and development expenses increased 3% to $27.8 million and
represented 2.7% of net sales.
     The Company initiated a plan to realign its operations
as a result of an in-depth strategic review of all of its operations. This
realignment resulted in impairment of assets charges and restructuring charges
in 2007 as follows:

of assets charges and restructuring and other exit costs.
     The Specialty Minerals segment recorded a loss from
operations of $20.0 million as compared with income from operations of $60.5
million in 2006. Included in the loss from operations was an impairment of
assets charge of $79.3 million and restructuring and other exit costs of $11.3
million.
     The Refractories segment recorded income from operations
of $11.5 million in 2007 as compared with $31.9 million in the prior year.
Included in income from operations in 2007 was an impairment of assets charge of
$14.8 million and restructuring and other exit costs of $4.7 million.
     Income from operations in 2006 increased 6% to $92.4

of sales in 2005. In 2006, income from operations for the Specialty Minerals
segment increased 2% to $60.5 million and was 9.0% of its net sales. Operating
income for the Refractories segment increased 13% to $31.9 million and was 9.2%
of its net sales. This was primarily attributable to increased profitability
from refractory products and systems sales, partially offset by a reduction in
profitability in metallurgical products.

an insurance recovery gains of approximately $3.0 million in 2007, $1.2 million
above prior year. In addition, the Company recorded higher interest income of
$1.3 million over prior year as a result of an increase in cash and cash
equivalents in 2007.

19

     Non-operating deductions increased 55% in 2006 from the
prior year. This increase was primarily due to increased interest expense of
$2.3 million over 2005 due to increased borrowings. In addition, in 2006 we
recognized an insurance settlement gain of approximately $1.8 million for
property damage sustained at one of our facilities. In 2005, we recognized a
litigation settlement gain of $2.1 million.

jurisdictions in which we were unable to record a tax benefit.
     The effective tax rate increased to 31.1% in 2006 as
compared with 30.1% in 2005. This increase was primarily related to a change in
the mix of earnings, an increase in the valuation allowance due to Ohio tax

Outlook

     We are presently experiencing some weakness in certain
primary industries we serve -- paper and construction. There were several paper
machine shutdowns that affected our satellite PCC product line as the paper
industry continues to consolidate and rationalize capacity. In addition, there
is continued softening in the residential construction and automotive markets
which is affecting our Processed Minerals product line. Steel production remains
stable with slow growth in our major markets, North America and Europe. However,
these markets have faced increased competition from other foreign markets in
which the Company has a lower market share. In addition, weakness in the
automotive and construction markets could result in reduced demand for this
sector.
     As a result of realigning and restructuring our
operations, we strengthened the basic foundation of our businesses. We
eliminated under-performing assets and expect to achieve higher returns on
capital and higher rates of profitable growth. However, we are concerned about
the state of the economy and the potential impact it may have on our product
lines.
     In 2008, we plan to focus on the following growth strategies:

•
Continued development and
potential commercial introduction of filler-fiber composite technology for
the paper industry to increase the fill-rates of uncoated freesheet paper.

•
Increase market penetration
of PCC by expanding the satellite model.

•
Emphasize higher value
specialty products and application systems to increase market penetration in
the Refractories segment.

•
Expand regionally into
emerging markets where we have a limited presence and increase our presence
in regional markets where the manufacturing of paper and steel is shifting,
particularly to China and Eastern Europe.

•
Development of unique calcium
carbonates used in the manufacture of biopolymers, an emerging market
opportunity.

•
Continue to improve our cost
competitiveness in all product lines.

•
Explore selective
acquisitions to complement our existing businesses.

     However, there can be no assurances that we will achieve success in
implementing any one or more of these strategies.
     In October 2006, we acquired ASMAS, an Istanbul-based
Turkish producer of refractories based in Istanbul, Turkey. This acquisition
provides our Refractories segment with a strong market position in Turkey, as
well as manufacturing capability which will enable us to service the rapidly
growing markets in the Middle East and Eastern Europe.
    As we continue to expand our operations overseas, we face
the inherent risks of doing business abroad, including inflation, fluctuations
in interest rates and currency exchange 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. Some of our
operations are located in areas that have experienced political or economic
instability, including Indonesia, Brazil, Thailand, China and South Africa. In
addition, our performance depends to some extent on that of the industries we
serve, particularly the paper manufacturing, steel manufacturing, and
construction industries.
     Our sales of PCC are predominantly pursuant to long-term
evergreen contracts, initially about ten years in length, with paper companies
at whose mills we operate satellite PCC plants. The terms of many of these
agreements have been extended, generally in connection with an expansion of the
satellite PCC plant. Failure of a number of our customers to renew existing
agreements on terms as favorable to us as those currently in effect could cause
our future sales growth rate to differ materially from our historical growth
rate and, if not renewed, could also result in impairment of the assets
associated with the PCC plant.

Liquidity and Capital Resources

     Cash flows provided from operations in 2007 were used
principally to fund $46.1 million of capital expenditures, to repay short-term
debt of $78.2 million and to repurchase $25.3 million of common shares for
treasury. Cash provided from operating activities totaled $179.7 million in 2007
as compared with $135.6 million in 2006. The increase in cash from operating
21

activities was primarily due to an improvement in working
capital, as compared to the prior year. Our accounts receivable declined despite
a 5% increase in sales, and our days of sales outstanding decreased to 55 days
from 59 days in the prior year. Our inventories also declined from the prior
year resulting in a reduction of days of inventory on hand from 56 days to 46
days. Included in cash flow from operations was pension plan funding of
approximately $24.1 million, $22.3 million and $12.9 million for the years ended
December 31, 2007, 2006 and 2005, respectively.
     On October 26, 2005, our Company's Board of Directors
authorized the Company's management, at its discretion, to repurchase up to $75
million in additional shares over the next three-year period. As of December 31,
2007, the Company had repurchased 1,231,872 shares under this program at an
average price of approximately $56.91 per share.
     On October 24, 2007, the Company's Board of Directors
authorized the Company's management to repurchase, at its discretion, up to $75
million of additional shares over the next two-year period. As of December 31,
2007, no shares have been purchased under this program.
     On January 31, 2008, our Board of Directors declared a
regular quarterly dividend on our common stock of $0.05 per share. No dividend
will be payable unless declared by the Board and unless funds are legally
available for payment.
     We have $187.6 million in uncommitted short-term bank
credit lines, of which $9.1 million was in use at December 31, 2007. We
anticipate that capital expenditures for 2008 should approximate $75 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: 2008 - $7.2 million; 2009
- $8.8 million; 2010 - $4.6 million; 2011 - $-- million; 2012 - $8.0; thereafter
- $89.6 million.
     The Company has contingent obligations associated with
unrecognized tax benefits, including interest and penalties, of approximately
$13.3 million.

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-term assets,
goodwill and other intangible assets, pension plan assumptions, income taxes,
asset retirement obligations, 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.
     We believe the following critical accounting policies
require us to make significant judgments and estimates in the preparation of our
consolidated financial statements:

•

Revenue recognition: Revenue from sale of products is
recognized at the time the goods are shipped and title passes to the
customer. In most of our PCC contracts, the price per ton is based upon the
total number of tons sold to the customer during the year. Under those
contracts, the price billed to the customer for shipments during the year is
based on periodic estimates of the total annual volume that will be sold to
the customer. Revenues are adjusted at the end of each year to reflect the
actual volume sold. There were no significant revenue adjustments in the
fourth quarter of 2007 and 2006, respectively. We have consignment
arrangements with certain customers in our Refractories segment. Revenues
for these transactions are recorded when the consigned products are consumed
by the customer. Revenues from sales of equipment are recorded upon
completion of installation and receipt of customer acceptance. Revenues from
services are recorded when the services are performed.

•

Allowance for doubtful accounts: Substantially all of our
accounts receivable are due from companies in the paper, construction and
steel industries. Accounts receivable are reduced by an allowance for
amounts that may become uncollectible in the future. Such allowance is
established through a charge to the provision for bad debt expenses. We
recorded bad debt expenses (recoveries) of $(0.1) million, $0.4 million and
$(0.5) million in 2007, 2006 and 2005, respectively. In addition to specific
allowances established for bankrupt customers, we also analyze the
collection history and financial condition of our other customers
considering current industry conditions and determine whether an allowance
needs to be established or adjusted.

22

•

Property, plant and equipment, goodwill, intangible and
other long-lived assets: 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. Our sales of PCC are
predominately pursuant to long-term evergreen contracts, initially ten years
in length, with paper mills at which we operate satellite PCC plants. The
terms of many of these agreements have been extended, often in connection
with an expansion of the satellite PCC plant. Failure of a PCC customer to
renew an agreement or continue to purchase PCC from our facility could
result in an impairment of assets or accelerated depreciation at such
facility.

•

Valuation of long-lived assets, goodwill and other
intangible assets: We assess the possible impairment of long-lived assets
and identifiable amortizable intangibles whenever events or changes in
circumstances indicate that the carrying value may not be recoverable.
Goodwill and other intangible assets with indefinite lives are reviewed for
impairment at least annually in accordance with the provisions of SFAS No.
142. Factors we consider important that could trigger an impairment review
include the following:

•

significant under-performance relative to historical or
projected future operating results;

•

significant changes in the manner of use of the
acquired assets or the strategy for the overall business;

•

significant negative industry or economic trends.

When we determine that the carrying value of intangibles,
long-lived assets or goodwill may not be recoverable based upon the
existence of one or more of the above indicators of impairment, we
principally measure any impairment by our ability to recover the carrying
amount of the assets from expected future operating cash flow on a
discounted basis. Net intangible assets, long-lived assets, and goodwill
amounted to $576.6 million as of December 31, 2007.

•

Accounting for income taxes: As part of the process of
preparing our consolidated financial statements, we are required to estimate
our income taxes in each of the jurisdictions in which we operate. This
process involves estimating current tax expense together with assessing
temporary differences resulting from differing treatments of items for tax
and accounting purposes. These differences result in deferred tax assets and
liabilities, which are included in the consolidated balance sheet. We must
then assess the likelihood that our deferred tax assets will be recovered
from future taxable income, and to the extent we believe that recovery is
not likely, we must establish a valuation allowance. To the extent we
establish a valuation allowance or increase this allowance in a period, we
must include an expense within the tax provision in the Consolidated
Statements of Operations.

The Company accounts for uncertain tax positions in
accordance with FASB Interpretation No. 48, "Accounting for Uncertainty in
Income Taxes" ("FIN 48"), an interpretation of FASB Statement No. 109 ("SFAS
109"). The application of income tax law is inherently complex. Laws and
regulations in this area are voluminous and are often ambiguous. As such, we
are required to make many subjective assumptions and judgements regarding
our income tax exposures. Interpretations of and guidance surrounding income
tax laws and regulations change over time. As such, changes in our
subjective assumptions and judgements can materially affect amounts
recognized in the consolidated balance sheets and statements of operations.
See Note 5 to the condensed consolidated financial statements, "Income
Taxes," for additional detail on our uncertain tax positions.

•

Pension Benefits: We sponsor pension and other retirement
plans in various forms covering the majority of employees who meet
eligibility requirements. Several statistical and actuarial models which
attempt to estimate future events are used in calculating the expense and
liability related to the plans. These models include assumptions about the
discount rate, expected return on plan assets and rate of future
compensation increases as determined by us, within certain guidelines. Our
assumptions reflect our historical experience and management's best judgment
regarding future expectations. In addition, our actuarial consultants also
use subjective factors such as withdrawal and mortality rates to estimate
these assumptions. The actuarial assumptions used by us may differ
materially from actual results due to changing market and economic
conditions, higher or lower withdrawal rates or longer or shorter life spans
of participants, among other things. Differences from these assumptions may
result in a significant impact to the amount of pension expense/liability
recorded by us follows:

       23

•

Asset Retirement Obligations: We currently record the
obligation for estimated asset retirement costs at a fair value in the
period incurred. Factors such as expected costs and expected timing of
settlement can affect the fair value of the obligations. A revision to the
estimated costs or expected timing of settlement could result in an
increase or decrease in the total obligation which would change the amount
of amortization and accretion expense recognized in earnings over time.
A one-percent increase or decrease in the discount rate
would change the total obligation by approximately $0.1 million.
A one-percent increase or decrease in the inflation
rate would change the total obligation by approximately $0.3 million.

•

The Company's accounts for stock-based compensation
expense under the provisions of SFAS No. 123R.
The Company uses the Black-Scholes option pricing model
to determine the fair value of 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 believe this
is a good indicator of future, actual and implied volatilities. For stock
options granted in the period ended December 31, 2007, the Company used a
volatility of 25.10%.
The expected life calculation was based upon the
observed and expected time to post-vesting forfeiture and exercise. For
stock options granted during the fiscal year ended December 31, 2007, the
Company used a 6.5 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 have
changed approximately $0.1 million in either direction for the year ended
December 31, 2007.

     For a detailed discussion on the application of these
and other accounting policies, see "Summary of Significant Accounting Policies"
in the "Notes to the Consolidated Financial Statements" in Item 15 of this
report, beginning on page F-6. This discussion and analysis should be read in
conjunction with the consolidated financial statements and related notes
included elsewhere in this report.

Prospective Information and Factors That May Affect Future
Results

     The SEC encourages companies to disclose forward-looking
information so that investors can better understand companies' future prospects
and make informed investment decisions. This report may contain forward-looking
statements that set our anticipated results based on management's plans and
assumptions. 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.
     We cannot guarantee that the outcomes suggested in any
forward-looking statement will be realized, although we believe we have been
prudent in our plans and assumptions. Achievement of future results is subject
to risks, uncertainties and the accuracy of 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

24

mind as they consider forward-looking statements and should
refer to the discussion of certain risks, uncertainties and assumptions in Item
1A, "Risk Factors."

Inflation

     Historically, inflation has not had a material adverse
effect on us. However, in recent years both business segments have been affected
by rapidly rising raw material and energy costs. The Company and its customers
will typically negotiate reasonable price adjustments in order to recover a
portion of these rapidly escalating costs. As 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.

Cyclical Nature of Customers' Businesses

     The bulk of our sales are to customers in the paper
manufacturing, steel manufacturing and construction industries, which have
historically been cyclical. The pricing structure of some of our long-term PCC
contracts makes our PCC business less sensitive to declines in the quantity of
product purchased. However, we cannot predict the economic outlook in the
countries in which we do business, nor in the key industries we serve. There can
be no assurance that a recession, in some markets or worldwide, would not have a
significant negative effect on our financial position or results of operations.

Recently Issued Accounting Standards

     In December 2007, the FASB issued Statement of Financial
Accounting Standards No. 141 (revised 2007), "Business Combinations" ("Statement
No. 141(R)"). Statement No. 141(R) changes the requirements for an acquirer's
recognition and measurement of the assets acquired and the liabilities assumed
in a business combination. Statement No. 141(R) is effective for annual periods
beginning after December 15, 2008 and should be applied prospectively for all
business combinations entered into after the date of adoption.
     In December 2007, the FASB issued Financial Accounting
Standards No. 160, "Noncontrolling Interests in Consolidated Financial
Statements - an amendment of ARB No. 51" ("Statement No. 160"). Statement No.
160 requires (i) that noncontrolling (minority) interests be reported as a
component of shareholders' equity, (ii) that net income attributable to the
parent and to the noncontrolling interest be separately identified in the
consolidated statement of operations, (iii) that changes in a parent's ownership
interest while the parent retains its controlling interest be accounted for as
equity transactions, (iv) that any retained noncontrolling equity investment
upon the deconsolidation of a subsidiary be initially measured at fair value,
and (v) that sufficient disclosures are provided that clearly identify and
distinguish between the interests of the parent and the interests of the
noncontrolling owners.. Statement No. 160 is effective for annual periods
beginning after December 15, 2008 and should be applied prospectively. However,
the presentation and disclosure requirements of the statement shall be applied
retrospectively for all periods presented. The adoption of the provisions of
Statement No. 160 is not anticipated to materially impact the Company's
consolidated financial position and results of operations.
     In September 2006, the FASB issued SFAS No. 157, "Fair
Value Measurements." This Statement defines fair value, establishes a framework
for measuring fair value under generally accepted accounting principles (GAAP),
and expands disclosures about fair value measurements. This Statement will apply
to all other accounting pronouncements that require fair value measurements.
This Statement is effective for financial statements issued for fiscal years
beginning after November 15, 2007, and interim periods within those fiscal
years. The Company expects the adoption of SFAS No. 157 will not have a material
impact on its financial statements.

     In February 2008, the FASB issued FSP FAS 157-1,
"Application of FASB No. 157 to FASB Statement No. 13 and Other Accounting
Pronouncements that Address Fair Value Measurements for Purposes of Lease
Classification or Measurement under Statement 13" and FSP FAS 157-2, "Effective
Date of FASB Statement No. 157." FSP 157-1 excludes fair measurements for
purposes of lease classification or measurement under FASB Statement 13 from the
fair value measurement under FASB Statement 157. FSP 157-2 defers the effective
date of Statement 157 for non-financial assets and non-financial liabilities to
fiscal years beginning after November 15, 2008.
     In November 2006, the Emerging Issues Task Force ("EITF")
reached a consensus on EITF issue 06-10, "Accounting for Deferred Compensation
and Postretirement Benefit Aspects of Collateral Assignment Split-Dollar Life
Insurance Arrangements." Employers will be required to measure the asset
associated with collateral-assignment split-dollar life insurance based on the
arrangement's terms and to record postretirement benefit liabilities only if the
employer will maintain the life insurance policy during the employee's
retirement or provide the employee with a death benefit. This consensus is
effective for fiscal years beginning after December 15, 2007. The Company is
expects the adoption of SFAS No. 157 will not have a material impact on its
financial statements.

25

     In February 2007, the FASB issued SFAS No. 159, "The
Fair Value Option for Financial Assets and Financial Liabilities." This
Statement allows entities to choose to measure financial instruments and certain
other items at fair value. This Statement is effective for fiscal periods
beginning after November 15, 2007. The Company is expects the adoption of SFAS
No. 157 will not have a material impact on its financial statements.

Item 7A.  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 change in the value of
foreign currencies would not have a material adverse effect on our financial
condition and results of operations. Approximately 50% of our bank debt bears
interest at variable rates; therefore our results of operations would only be
affected by interest rate changes to such bank debt outstanding. An immediate
10% 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 had open
forward exchange contracts to purchase approximately $5.3 million and $4.7
million of foreign currencies as of December 31, 2007 and 2006, respectively.
These contracts mature between January and July of 2008. The fair value of these
instruments at both December 31, 2007 and December 31, 2006 was a liability of
$0.1 million.

Item 8.   Financial Statements and Supplementary Data

     The financial information required by Item 8 is
contained in Item 15 of Part IV of this report.

Item 9.   Changes in and Disagreements with Accountants on
Accounting and Financial Disclosure

     None.

Item 9A.  Controls and Procedures

Disclosure Controls and Procedures

     The Company's management, under the supervision and with
the participation of the Company's Chief Executive Officer and Chief Financial
Officer, carried out an evaluation of the effectiveness of the design and
operation of the Company's disclosure controls and procedures as of the end of
the period covered by this report pursuant to Exchange Act Rule 13a -15. The
Company's disclosure controls and procedures are designed to ensure that
information required to be disclosed is recorded, processed, summarized and
reported within the time periods specified in SEC rules and forms. Based upon
this evaluation, the Chief Executive Officer and Chief Financial Officer
concluded that the Company's disclosure controls and procedures (as defined in
Rules 13(a)-15(b) under the Securities Exchange Act of 1934) were effective in
ensuring that material information required to be disclosed by the Company in
reports that we file or submit under the Exchange Act is recorded, processed,
summarized and reported on a timely basis.
     Pursuant to Section 404 of the Sarbanes-Oxley Act of
2002, we have included a report of management's assessment of the design and
operating effectiveness of our internal controls as part of this report.
Management's report is included in our consolidated financial statements
beginning on page F-1 of this report under the captions entitled "Management's
Report on Internal Control Over Financial Reporting."
     The Company is in the process of implementing a global
enterprise resource planning ("ERP") system to manage our business operations.
As of December 31, 2007, all of our domestic locations were using the new
systems. 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 the migration to the new ERP system could adversely
affect the Company's disclosure controls and procedures or our results of
operations in future periods. 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.

26

Changes in Internal Control Over Financial Reporting

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

SUBSIDIARY COMPANIES

NOTES OF CONSOLIDATED FINANCIAL STATEMENTS

Note 1.   Summary of Significant Accounting Policies

     Basis of Presentation

     The accompanying consolidated financial statements
include the accounts of Minerals Technologies Inc. (the "Company") and its
wholly and majority-owned subsidiaries. All intercompany balances and
transactions have been eliminated in consolidation.
     Certain reclassifications were made to prior year
amounts to conform with the current year presentation. See Note 4, "Discontinued
Operations" for further information.
     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, valuation allowances, and
litigation and environmental liabilities. Actual results could differ from those
estimates.
     Business

     The Company is a resource- and technology-based company
that develops, produces and markets on a worldwide basis a broad range of
specialty mineral, mineral-based products and related systems and technologies.
The Company's products are used in manufacturing processes of the paper and
steel industries, as well as by the building materials, polymers, ceramics,
paints and coatings, and other manufacturing industries.
     Cash Equivalents and Short-term Investments

     The Company considers all highly liquid investments with
original maturities of three months or less to be cash equivalents. Cash
equivalents amounted to $4.7 million and $4.0 million at December 31, 2007 and
2006, respectively. Short-term investments consist of financial instruments with
original maturities beyond three months. Short-term investments amounted to $9.7
million and $8.4 million at December 31, 2007 and 2006, respectively.
     Trade Accounts Receivable

     Trade accounts receivables are recorded at the invoiced
amount and do not bear interest. The allowance for doubtful accounts is the
Company's best estimate of the amount of probable credit losses in the Company's
existing accounts receivable. The Company determines the allowance based on
historical write-off experience and specific allowances for bankrupt customers.
The Company also analyzes the collection history and financial condition of its
other customers, considering current industry conditions and determines whether
an allowance needs to be established. The Company reviews its allowance for
doubtful accounts monthly. Past due balances over 90 days based on payment terms
are reviewed individually for collectibility. Account balances are charged off
against the allowance after all means of collection have been exhausted and the
potential for recovery is considered remote. The Company does not have any
off-balance-sheet credit exposure related to its customers.
     Inventories

     Inventories are valued at the lower of cost or market.
Cost is determined by the first-in, first-out (FIFO) method.
     Additionally, as required by SFAS No. 151, "Inventory
Costs - an Amendment of ARB No. 43, Chapter 4," items such as idle facility
expense, excessive spoilage, freight handling costs and re-handling costs are
recognized as current period charges. The allocation of fixed production
overheads to the costs of conversion are based upon the normal capacity of the
production facility. Fixed overhead costs associated with idle capacity are
expensed as incurred.
     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 our PCC production facilities and machinery and equipment
pertaining to our natural stone mining and processing plants and our 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
F-6

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES

NOTES OF CONSOLIDATED FINANCIAL STATEMENTS
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. 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.
     Depletion of mineral reserves is determined on a
unit-of-extraction basis for financial reporting purposes, based upon proven and
probable reserves, and on a percentage depletion basis of tax purposes.
     Stripping Costs Incurred During Production

     The Company accounts for stripping costs in accordance
with 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 the 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," and EITF 04-3, "Mining Assets: Impairment and Business
Combinations." 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.
     Goodwill and Other Intangible Assets

     Goodwill represents the excess of purchase price and
related costs over the value assigned to the net tangible and identifiable
intangible assets of businesses acquired. The Company accounts for goodwill and
other intangible assets under 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 tested for impairment at least
annually in accordance with the provisions of SFAS No. 142. SFAS No. 142 also
requires that intangible assets with estimable useful lives be amortized over
their respective estimated lives to the estimated residual values, and reviewed
for impairment in accordance with SFAS No. 144, "Accounting for the Impairment
or Disposal of Long-Lived Assets."
     The Company evaluates the recoverability of goodwill
using a two-step impairment test approach at the reporting unit level. In the
first step, the fair value for the reporting unit is compared to its book value
including goodwill. In the case that the fair value of the reporting unit is
less than book value, a second step is performed which compares the fair value
of the reporting unit's goodwill to the book value of the goodwill. The fair
value for the goodwill is determined based on the difference between the fair
values of the reporting unit and the net fair values of the identifiable assets
and liabilities of such reporting unit. If the fair value of the goodwill is
less than the book value, the difference is recognized as an impairment.
     Accounting for Asset Retirement Obligations

     The Company accounts for asset retirement obligations in
accordance with SFAS No. 143, "Accounting for Asset Retirement Obligations" and
under the provisions of FASB Interpretation No. 47, "Accounting for Conditional
Asset Retirement Obligations." SFAS No. 143 establishes the financial accounting
and reporting for obligations associated with the retirement of long-lived
assets and the associated asset retirement costs. 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. FASB Interpretation No. 47 includes
legal obligations to perform asset retirement activities where timing or method
of settlement are conditional on future events.
     Fair Value of Financial Instruments

     The recorded amounts of cash and cash equivalents,
receivables, short-term borrowings, accounts payable, accrued interest, and
variable-rate long-term debt approximate fair value because of the short
maturity of those instruments or the variable nature of underlying interest
rates. Short-term investments are recorded at cost, which approximates fair
market value.

F-7

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES

NOTES OF CONSOLIDATED FINANCIAL STATEMENTS
     Derivative Financial Instruments

     The Company accounts for derivative financial
instruments which are used to hedge certain foreign exchange risk in accordance
with SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities," as amended by SFAS No. 138, "Accounting for Certain Derivative
Instruments and Certain Hedging Activities." See the Notes on Derivative
Financial Instruments and Hedging Activities and Financial Instruments and
Concentrations of Credit Risk in the Consolidated Financial Statements for a
full description of the Company's hedging activities and related accounting
policies.
     Revenue Recognition

     Revenue from sale of products is recognized at the time
the goods are shipped and title passes to the customer. In most of the Company's
PCC contracts, the price per ton is based upon the total number of tons sold to
the customer during the year. Under those contracts the price billed to the
customer for shipments during the year is based on periodic estimates of the
total annual volume that will be sold to such customer. Revenues are adjusted at
the end of each year to reflect the actual volume sold. The Company also has
consignment arrangements with certain customers in our Refractories segment.
Revenues for these transactions are recorded when the consigned products are
consumed by the customer.
     Revenues from sales of equipment are recorded upon
completion of installation and receipt of customer acceptance. Revenues from
services are recorded when the services have been performed.
     Foreign Currency

     The assets and liabilities of the Company's
international subsidiaries are translated into U.S. dollars using exchange rates
at the respective balance sheet date. The resulting translation adjustments are
recorded in accumulated other comprehensive income (loss) in shareholders'
equity. Income statement items are generally translated at monthly average
exchange rates prevailing during the period. International subsidiaries
operating in highly inflationary economies translate non-monetary assets at
historical rates, while net monetary assets are translated at current rates,
with the resulting translation adjustments included in net income. At December
31, 2007, the Company had no international subsidiaries operating in highly
inflationary economies.
     Income Taxes

     Income taxes are provided for based on the asset and
liability method of accounting pursuant to SFAS No. 109, "Accounting for Income
Taxes." Under SFAS No. 109, deferred tax assets and liabilities are recognized
for the estimated future tax consequences attributable to differences between
the financial statement carrying amounts of existing assets and liabilities and
their respective tax bases. Deferred tax assets and liabilities are measured
using enacted tax rates in effect for the year in which those temporary
differences are expected to be recovered or settled. Under SFAS No. 109, the
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in income in the period that includes the enactment date.
     The Company operates in multiple taxing jurisdictions,
both within the U.S. 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 regularly assesses its tax position for such transactions
and includes reserves for those differences in position. The reserves are
utilized or reversed once the statute of limitations has expired or the matter
is otherwise resolved.

     The Company accounts for uncertain tax positions in
accordance with FASB Interpretation No. 48, "Accounting for Uncertainty in
Income Taxes" ("FIN 48"), an interpretation of FASB Statement No. 109 ("SFAS
109"). The application of income tax law is inherently complex. Laws and
regulations in this area are voluminous and are often ambiguous. As such, we are
required to make many subjective assumptions and judgements regarding our income
tax exposures. Interpretations of and guidance surrounding income tax laws and
regulations change over time. As such, changes in our subjective assumptions and
judgements can materially affect amounts recognized in the consolidated balance
sheets and statements of income. The Company's accounting policy is to recognize
interest and penalties as part of its provision for income taxes. See Note 5 to
the consolidated financial statements, "Income Taxes," for additional detail on
our uncertain tax positions.
     The accompanying financial statements generally do not
include a provision for U.S. income taxes on international subsidiaries'
unremitted earnings, which are expected to be permanently reinvested overseas.
     Research and Development Expenses

     Research and development expenses are expensed as
incurred.

     Accounting for Stock-Based Compensation

     The Company accounts for share-based compensation in
accordance with SFAS No. 123R, "Share-Based Payment." Under the provisions of
SFAS No. 123R, the Company recognizes compensation expense for share-based
awards based upon the grant date fair value over the vesting period.

F-8

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES

NOTES OF CONSOLIDATED FINANCIAL STATEMENTS
     Pension and Post-retirement Benefits

     The Company has defined benefit pension plans covering
the majority of its employees. The benefits are generally based on years of
service and an employee's modified career earnings.
     The Company also provides post-retirement healthcare
benefits for the majority of its retirees and employees in the United States.
The Company measures the costs of its obligation based on its best estimate. The
net periodic costs are recognized as employees render the services necessary to
earn the post-retirement benefits.
     Environmental

     Expenditures that relate to current operations are
expensed or capitalized as appropriate. Expenditures that relate to an existing
condition caused by past operations and which do not contribute to current or
future revenue generation are expensed. Liabilities are recorded when it is
probable the Company will be obligated to pay amounts for environmental site
evaluation, remediation or related costs, and such amounts can be reasonably
estimated.
     Earnings Per Share

     Basic earnings per share have been computed based upon
the weighted average number of common shares outstanding during the period.
     Diluted earnings per share have been computed based upon
the weighted average number of common shares outstanding during the period
assuming the issuance of common shares for all potentially dilutive common
shares outstanding.

Note 2.   Stock-Based Compensation

     The Company has a 2001 Stock Award and Incentive Plan
(the "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 (loss) for years ended 2007 and 2006 include
$2.4 million and $2.3 million pretax compensation costs, respectively, related
to stock option expense as a component of marketing and administrative expenses.
All stock option expense is recognized in income. The related tax benefit
included in the statement of operations on the non-qualified stock options is
$0.6 million and $0.5 million for 2007 and 2006, respectively.
      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. 123R, the benefits of tax deductions in excess of the tax benefit
of compensation costs recognized or would have been recognized under SFAS No.
123 for those options are classified as financing inflows on the consolidated
statement of cash flows.
      The following table shows the pro forma effects on net
income and earnings per share for the year ended December 31, 2005 had
compensation cost been recognized in accordance with SFAS No. 123, as amended by
SFAS No. 148 "Accounting for Stock-Based Compensation - Transition and
Disclosure."

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 assumption used for the period ended December
31, 2007 was approximately 8%.
     The weighted average grant date fair value for stock
options granted during the years ended December 31, 2007, 2006 and 2005 was
$21.61, $18.97 and $24.13, respectively. The weighted average grant date fair
value for stock options vested during 2007 and 2006 was $20.83. The total
intrinsic value of stock options exercised during the years ended December 31,
2007 and 2006 was $9.4 million and $1.8 million, respectively.
      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 years ended December 31, 2007, 2006 and

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.

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 "Plan"). The rights will be deferred for a
specified number of years of service, subject to restrictions on transfer and
other conditions. Under the provisions of SFAS No. 123R compensation expense for
these shares is recognized over the vesting period. The Company granted 87,650
shares and 50,300 shares for the periods ended December 31, 2007 and 2006,
respectively. The fair value was determined based on the market value of
unrestricted shares. The discount for the restriction was not significant. As of
December 31, 2007, there was unrecognized stock-based compensation related to
restricted stock of $4.7 million, which will be recognized over approximately
the next three years. The compensation expense amortized with respect to all
units was approximately $2.8 million and $1.7 million for the periods ended
December 31, 2007 and 2006, respectively. In addition, the Company recorded $1.0
million in reversals related to restricted stock forfeitures. Such costs and
reversals are included in marketing and administrative expenses. There were
33,363 restricted stock shares that were vested as of December 31, 2007.

Additionally, options to purchase 154,133 shares and 371,587 shares of common
stock for the years ended December 31, 2007 and December 31, 2006, respectively,
were not included in the computation of diluted earnings per share because they
were anti-dilutive, as the exercise prices of the options were greater than the
average market price of the common shares.

Note 4.   Discontinued Operations

     During the third quarter of 2007, the Company conducted
an in-depth strategic review of its operations. This review resulted in a
realignment of its operations, which included the exiting of certain businesses.
     Accordingly, during the fourth quarter of 2007, the
Company classified its Synsil operations and its plants at Mount Vernon and
Wellsville as discontinued operations. These operations were part of the
Company's Specialty Minerals segment. The assets of these operations are held
and available for sale. The Company expects the sale of these assets to be
completed within a one-year time frame. The Company does not anticipate the
ongoing cash flows of these operations until disposition to be material.
     In April 2006, the Company ceased operation at its
one-unit satellite PCC facility in Hadera, Israel. In the fourth quarter, the
Company recorded a loss from discontinued operations of approximately $1.7
million upon liquidation of its investment
F-12

in Israel. This loss was predominantly related to the
recognition of foreign currency translation losses previously recognized in
accumulated other comprehensive income (loss).
     The consolidated financial statements for all prior
periods presented have been reclassified to reflect these businesses in
discontinued operations.
     The following table details selected financial
information for the discontinued operation in the consolidated statements of

     The Company established a valuation allowance of
approximately $0.5 million as of December 31, 2007. This valuation allowance
relates to net operating loss carry forwards in Mexico where there is an
uncertainty regarding its realizability.
     The Company recorded $3.5 million of deferred tax assets
arising from tax loss carry forwards which will be realized through future
operations. Carry forwards of approximately $0.3 million expires in 5 years,
$1.2 million expire over the next 15 years, and $2 million can be utilized over
an indefinite period.
     On January 1, 2007, the Company adopted the provisions
of FASB Interpretation No. 48 (FIN 48), "Accounting for Uncertainty in Income
Taxes." FIN 48 specifies the way companies are to account for uncertainty in
income tax reporting and prescribes a recognition threshold and measurement
attribute for tax positions taken or expected to be taken in a tax return. As a
result of the adoption of FIN 48, the Company recognized a $1.9 million decrease
in the liability for unrecognized income tax benefits, resulting in an increase
to the January 1, 2007 balance of retained earnings.
     As of the date of adoption of FIN 48, the Company had
approximately $9.0 million of total unrecognized income tax benefits and $2.3
million of interest and penalties. On December 31, 2007, the Company had $10.4
million of total unrecognized tax benefits. Included in this amount were a total
of $6 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 following table summarizes the activity related to
our unrecognized tax benefits:

     The Company's accounting policy prior to the adoption of
FIN 48 and upon the adoption of FIN 48 is to recognize interest and penalties
accrued, relating to unrecognized income tax benefits as part of its provision
for income taxes. The Company accrued $0.6 million of interest and penalties
during 2007 and have a total accrued balance on December 31, 2007 of $2.9
million.
     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 European income tax examinations by
tax authorities for years prior to 2003.

     Net cash paid for income taxes were $16.8 million, $18.0
million and $21.2 million for the years ended December 31, 2007, 2006 and 2005,
respectively.
     In December 2004, the FASB issued SFAS No. 109-2,
"Accounting and Disclosure Guidance for the Foreign Earnings Repatriation
Provision within the American Jobs Creation Act of 2004," which provides relief
concerning the timing of the SFAS No. 109 requirement to accrue deferred taxes
for unremitted earnings of foreign subsidiaries. On October 22, 2004, the
American Jobs Act Creation Act of 2004 ("AJCA") was signed into law. The AJCA
includes a special, one-time, 85% dividends received deduction for certain
foreign earnings that are repatriated. The Company repatriated $18.5 million in
2005 under this Act, which resulted in a tax liability of approximately $1.2
million and increased the effective tax rate by 1.5%.

Note 6.   Foreign Operations

     The Company has not provided for U.S. federal and
foreign withholding taxes on $155.8 million of foreign subsidiaries'
undistributed earnings as of December 31, 2007 because such earnings are
intended to be permanently reinvested overseas. To the extent the parent company
has received foreign earnings as dividends, the foreign taxes paid on those
earnings have generated tax credits, which have substantially offset related
U.S. income taxes. However, in the event that the entire $155.8 million of
foreign earnings were to be repatriated, incremental taxes may be incurred. We
do not believe this amount would be more than $16 million.
     Net foreign currency exchange gains (losses), included
in non-operating deductions in the Consolidated Statements of Income, were
$513,000, $(268,000) and $(450,000) for the years ended December 31, 2007, 2006

Note 9.   Restructuring Costs

     Following an in-depth review of all our operations and
development of a new strategic focus, the Company recorded a pre-tax charge of
$16.0 million for restructuring and other costs. The restructuring will result
in a total workforce reduction of approximately 200 employees. This charge
consists of severance and other employee benefit costs, contract termination
costs and other exit costs. The following table reflects components of the

Note 10.   Acquisitions

     In October 2006, the Company acquired all of the
outstanding stock of ASMAS, an Istanbul-based Turkish producer of refractories
for approximately $32.4 million in cash. The terms of the acquisition provide
for an additional purchase price of up to $5 million to be paid in 2009 based
upon performance criteria through 2008. The operations of this entity have
been included in the Refractories segment of the Company's financial statements
since the date of the acquisition.

system in electric steelmaking and ladle furnaces. The Company recorded
tax-deductible goodwill of approximately $1.3 million in connection with this
acquisition.

Note 11.  Goodwill and Other Intangible Assets

   The carrying amount of goodwill was $72.0 million and
$69.0 million as of December 31, 2007 and December 31, 2006, respectively. The
net change in goodwill since December 31, 2006 was primarily attributable to the
effect of foreign exchange.

Amortization expense was approximately $1.5 million, $0.8 million and $0.3
million for the years ended December 31, 2007, 2006 and 2005, respectively. The
estimated amortization expense is $1.2 million for each of the next five years
through 2012.
     Included in other assets and deferred charges is an
additional intangible asset of approximately $5.5 million which represents the
non-current unamortized amount paid to a customer in connection with contract
extensions at eight satellite PCC 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 $1.8 million was amortized in 2007, 2006
and 2005, respectively. Estimated amortization as a reduction of sales is as
follows: 2008 - $1.8 million; 2009 - $1.5 million; 2010 - $1.2 million; 2011 -
$0.9 million; 2012 - $0.6 million; with smaller reductions thereafter over the
remaining lives of the contracts.

Note 12.  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 also establishes a uniform accounting model for
the disposal of long-lived assets. 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. In such instances, the Company estimates the
undiscounted future cash flows (excluding interest) that result from the use of
the asset and its ultimate disposition. If the sum of the undiscounted cash
flows (excluding interest) that 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.
     During the third quarter of 2007, following an in-depth
strategic review of all its operations, the Company recorded a charge of $140.9
million, of which $46.8 million was reclassified to discontinued operations, as
part of a program to realign its operations by consolidating operations within
certain product lines and exiting certain businesses. Major components of this
realignment include an exit from our Synsil^® Products product line;
consolidation of our Specialty PCC operations in the United States; sale of our
two plants in the Midwest that process imported ore in the Processed Minerals
product line; modification of our strategy for coating PCC resulting in the
anticipated closure of one facility; and a slower than anticipated market
penetration at our refractories facility in China resulting in an impairment of
assets charge.
     The impairment charge relates to all product lines. The

NOTES OF CONSOLIDATED FINANCIAL STATEMENTS

Note 13.   Derivative Financial Instruments and Hedging
Activities

     The Company is exposed to foreign currency exchange rate
fluctuations. As part of its risk management strategy, the Company uses forward
exchange contracts (FEC) to manage its exposure to foreign currency risk on
certain raw material purchases. The Company's objective is to offset gains and
losses resulting from these exposures with gains and losses on the derivative
contracts used to hedge them. The Company has not entered into derivative
instruments for any purpose other than to hedge certain expected cash flows. The
Company does not speculate using derivative instruments.
     By using derivative financial instruments to hedge
exposures to changes in interest rates and foreign currencies, the Company
exposes itself to credit risk and market risk. Credit risk is the risk that the
counterparty will fail to perform under the terms of the derivative contract.
When the fair value of a derivative contract is positive, the counterparty owes
the Company, which creates credit risk for the Company. When the fair value of a
derivative contract is negative, the Company owes the counterparty, and
therefore, it does not face any credit risk. The Company minimizes the credit
risk in derivative instruments by entering into transactions with major
financial institutions.
     Market risk is the adverse effect on the value of a
financial instrument that results from a change in interest rates, currency
exchange rates, or commodity prices. The market risk associated with interest
rate and forward exchange contracts is managed by establishing and monitoring
parameters that limit the types and degree of market risk that may be
undertaken.
     Based on criteria established by SFAS No. 133, the
Company designated its derivatives as cash flow hedges. During 2001, the Company
entered into three-year interest rate swap agreements with notional amounts
totaling $30 million that expired in January 2005. These agreements effectively
converted a portion of the Company's floating-rate debt to a fixed-rate basis
with an interest rate of 4.5%, thus reducing the impact of the interest rate
changes on future cash flows and income. The Company uses FEC's designated as
cash flow hedges to protect against foreign currency exchange rate risks
inherent in its forecasted inventory purchases. The Company had 14 open foreign
exchange contracts as of December 31, 2007.
     For derivative instruments that are designated and
qualify as cash flow hedges, the effective portion of the gain or loss on the
derivative instrument is initially recorded in accumulated other comprehensive
income (loss) as a separate component of shareholders' equity and subsequently
reclassified into earnings in the period during which the hedged transaction is
recognized in earnings. The gains and losses associated with these forward
exchange contracts are recognized into cost of sales. Gains and losses and hedge
ineffectiveness associated with these derivatives were not significant.

short-term bank deposits held at December 31, 2007 since the carrying amount
approximates fair market value.

Note 15.  Financial Instruments and Concentrations of Credit
Risk

     The following methods and assumptions were used to
estimate the fair value of each class of financial instrument:
     Cash and cash equivalents, short-term investments,
accounts receivable and payable: The carrying amounts approximate fair value
because of the short maturities of these instruments.
     Short-term debt and other liabilities: The
carrying amounts of short-term debt and other liabilities approximate fair value
because of the short maturities of these instruments.
     Long-term debt: The fair value of the long-term
debt of the Company is estimated based on the quoted market prices for that debt
or similar debt and approximates the carrying amount.
     Forward exchange contracts:
The fair value of forward exchange contracts (used for hedging purposes) is
estimated by obtaining quotes from brokers. If appropriate, the Company would
enter into forward exchange contracts to mitigate the impact of foreign exchange
rate movements on the Company's operating results. It does not engage in
speculation. Such

F-19

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES

NOTES OF CONSOLIDATED FINANCIAL STATEMENTS
foreign exchange contracts would offset losses and gains on
the assets, liabilities and transactions being hedged. At December 31, 2007, the
Company had open foreign exchange contracts with a financial institution to
purchase approximately $5.3 million of foreign currencies. These contracts range
in maturity from January 22, 2008 to July 7, 2008. The fair value of these
instruments was a liability of $0.1 million at both December 31, 2007 and
December 31, 2006.
     Credit risk: Substantially all of the Company's
accounts receivable are due from companies in the paper, construction and steel
industries. Credit risk results from the possibility that a loss may occur from
the failure of another party to perform according to the terms of the contracts.
The Company regularly monitors its credit risk exposures and takes steps to
mitigate the likelihood of these exposures resulting in actual loss. The
Company's extension of credit is based on an evaluation of the customer's
financial condition and collateral is generally not required.
     The Company's bad debt expense (recoveries) for the
years ended December 31, 2007, 2006 and 2005 was $(0.1) million, $0.4 million
and $(0.5) million, respectively.

     On June 9, 2000 the Company entered into a twenty-year,
taxable, Variable/Fixed Rate Industrial Development Revenue Bond agreement to
finance a portion of the construction of a merchant manufacturing facility for
the production of Specialty PCC in Brookhaven, Mississippi. This facility has
ceased operations during the first quarter of 2008 and the Company intends to
repay this obligation in 2008. The Company has selected the variable rate option
for this borrowing and the average interest rate was approximately 5.87% and
5.65% for the years ended December 31, 2007 and 2006, respectively.
     On May 31, 2003, the Company acquired land and limestone
ore reserves from the Cushenbury Mine Trust for approximately $17.5 million.
Approximately $6.1 million was paid at the closing and $11.4 million was
financed through an installment obligation. The interest rate on this obligation
is approximately 4.25%. For the year ending December 31, 2007, $0.9 million of
principal was paid on this debt. Principal payments are as follows: 2008 - $6.5
million; 2013 - $1.4 million.
     On October 5, 2006, the Company, through private
placement, entered into a Note Purchase Agreement and issued $75 million
aggregate principal amount unsecured senior notes. These notes consist of two
tranches: $50 million aggregate principal amount 5.53% Series 2006A Senior Notes
(Tranche 1 Notes); and $25 million aggregate principal amount Floating Rate
Series 2006A Senior Notes (Tranche 2 Notes). Tranche 1 Notes bear interest of

into a series of Renminbi ("RMB") denominated loan agreements through two of its
consolidated joint ventures in China with Communication Bank of China, totaling
RMB 60,000,000. During 2007, the Company repaid RMB 25,000,000 of principal
related to these loans. The assets of the PCC facilities operated by these
consolidated joint ventures were pledged as collateral for RMB 43,000,000 of the
loans. The loan agreements bear a variable interest rate based on the People's
Bank of China base rate, and mature between January 29, 2009 and March 26, 2009.
The interest rate on these loans was approximately 7.12%.
     The aggregate maturities of long-term debt are as
follows: 2008 - $7.2 million; 2009 - $8.8 million; 2010 - $4.6 million; 2011 -

Note 17.  Benefit Plans

     Pension Plans and Other Postretirement Benefit Plans

     The Company and its subsidiaries have pension plans
covering the majority of eligible employees on a contributory or
non-contributory basis.

F-21

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES

NOTES OF CONSOLIDATED FINANCIAL STATEMENTS
     Benefits under defined benefit plans are generally based
on years of service and an employee's career earnings. Employees generally
become fully vested after five years.
     The Company provides postretirement health care and life
insurance benefits for the majority of its U.S. retired employees. Employees are
generally eligible for benefits upon retirement and completion of a specified
number of years of creditable service. The Company does not pre-fund these
benefits and has the right to modify or terminate the plan in the future.

     Unrecognized prior service cost is amortized over the

     Under the provisions of SFAS No. 88, lump-sum
distributions from terminations, resulted in a plan curtailment of one of the
Company's pension plans and also caused partial settlement of such plan. As a
result, there was a curtailment loss in income from operations of $0.1 million
in 2007 and a curtailment gain in income from operations of $0.8 million in
2006.
     Under the provisions of SFAS No. 88, lump-sum
distributions from the Company's Supplemental Retirement Plan caused a partial
settlement of such plan, resulting in a charge of $0.3 million in 2005.
     The Company's funding policy for U.S. plans generally is
to contribute annually into trust funds at a rate that provides for future plan
benefits and maintains appropriate funded percentages. Annual contributions to
the U.S. qualified plans are at least sufficient to satisfy regulatory funding
standards and are not more than the maximum amount deductible for income tax
purposes. The funding policies for the international plans conform to local
governmental and tax requirements. The plans' assets are invested primarily in
stocks and bonds.

     The Company considers a number of factors to determine
its expected rate of return on plan assets assumptions, including historical
performance of plan assets, asset allocation and other third-party studies and
surveys. The Company reviewed the historical performance of plan assets over a
ten-year period (from 1997 to 2007), the results of which exceed the 8.50% rate
of return assumption that the Company ultimately selected for domestic plans.
The Company also considered plan portfolio asset allocations over a variety of
time periods and compared them with third-party studies and surveys of
annualized returns of similarly balanced portfolio strategies. The historical
return of this universe of similar portfolios also exceeded the return
assumption that the Company ultimately selected. Finally, the Company reviewed
performance of the capital markets in recent years and, upon advice from various
third parties, such as the pension plans' advisers, investment managers and
actuaries, selected the 8.50% return assumption used for domestic plans.
     The Company's Plan stipulates that the maximum health
care cost trend rate will be 5%.

     Investment Strategies

     The Plan Assets Committee has adopted an investment
policy for domestic pension plan assets designed to meet or exceed the expected
rate of return on plan assets assumption. To achieve this, the pension plans
retain professional investment managers that invest plan assets, primarily in
equity and fixed income securities. The Company has targeted an investment mix
of 65% in equity securities and 35% in fixed income securities.
     Savings and Investment Plans

     The Company maintains a voluntary Savings and Investment
Plan for most non-union employees in the U.S. Within prescribed limits, the
Company bases its contribution to the Plan on employee contributions. The
Company's contributions amounted to $3.4 million, $3.3 million and $3.0 million
for the years ended December 31, 2007, 2006 and 2005, respectively.

Notes 18.  Leases

     The Company has several non-cancelable operating leases,
primarily for office space and equipment. Rent expense amounted to approximately
$7.0 million, $6.1million and $4.6 million for the years ended December 31,
2007, 2006 and 2005, respectively. Total future minimum rental commitments under
all non-cancelable leases for each of the years 2008 through 2012 and in
aggregate thereafter are approximately $5.1 million, $3.7 million, $2.8 million,
$1.4 million, $0.9 million, respectively, and $8.9 million thereafter. Total
future minimum rentals to be received under non-cancelable subleases were
approximately $4.3 million at December 31, 2007.
     Total future minimum payments to be received under
direct financing leases for each of the years 2008 through 2012 and the
aggregate thereafter are approximately: $6.7 million, $3.8 million, $3.1
million, $2.0 million, $1.1 million, and $2.1 million thereafter.

Note 19.  Litigation

     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 310 pending silica
cases and 26 pending asbestos cases. To date, 1,155 silica cases and 1 asbestos
case 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 in 2006 was $0.1 million. Costs for the
legal defense of these cases in 2007 were $78,500. Our experience has been that
MTI is not liable to plaintiffs in any of these lawsuits and MTI 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 ("DEP") 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

F-25

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES

NOTES OF CONSOLIDATED FINANCIAL STATEMENTS
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 a report
characterizing the contamination. We are awaiting review and approval of
this report 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 are still conducting investigations
of potential groundwater contamination. To date, the results of
investigation indicate that there is some oil contamination of the
groundwater. We are conducting further investigations of the groundwater.

•

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 $200,000, 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 is
being undertaken pursuant to an administrative consent order issued by the
Massachusetts Department of Environmental Protection on June 18, 2002. The order
required payment of a civil fine in the amount of $18,500, the investigation of
options for ensuring that the facility's wastewater treatment ponds will not
result in discharge to groundwater, and closure of a historic lime solids
disposal area. The Company informed the Massachusetts Department of
Environmental Protection of proposed improvements to the wastewater treatment
system on June 29, 2007, and is committed to implementing the improvements by
June 1, 2012. Preliminary engineering reviews indicate that the estimated cost
of these upgrades to operate this facility beyond 2012 may be between $6 million
and $8 million. The Company estimates that remediation costs would approximate
$500,000, which has been accrued as of December 31, 2007.
     The Company and its subsidiaries are not party to any
other material pending legal proceedings, other than routine litigation
incidental to their businesses.

Note 20.  Stockholders' Equity

Capital Stock

     The Company's authorized capital stock consists of 100
million shares of common stock, par value $0.10 per share, of which 19,090,139
shares and 19,085,528 shares were outstanding at December 31, 2007 and 2006,
respectively, and 1,000,000 shares of preferred stock, none of which were issued
and outstanding.

Cash Dividends

     Cash dividends of $3.8 million or $0.20 per common share
were paid during 2007. In January 2008, a cash dividend of approximately $1.0
million or $0.05 per share, was declared, payable in the first quarter of 2008.

Preferred Stock Purchase Rights

     Under the Company's Preferred Stock Purchase Rights
Plan, each share of the Company's common stock carries with it one preferred
stock purchase right. Subject to the terms and conditions set forth in the plan,
the rights will become exercisable if a person or group acquires beneficial
ownership of 15% or more of the Company's common stock or announces a tender or
exchange offer that would result in the acquisition of 30% or more thereof. If
the rights become exercisable, separate certificates evidencing the rights will
be distributed, and each right will entitle the holder to purchase from the
Company a new series of preferred stock, designated as Series A Junior Preferred
Stock, at a predefined price. The rights also entitle the holder to purchase
shares in a change-of-control situation. The preferred stock, in addition to a
preferred dividend and liquidation right, will entitle the holder to vote on a
pro rata basis with the Company's common stock.

F-26

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES

NOTES OF CONSOLIDATED FINANCIAL STATEMENTS

     The rights are redeemable by the Company at a fixed
price until 10 days or longer, as determined by the Board, after certain defined
events or at any time prior to the expiration of the rights on September 13,
2009 if such events do not occur.

Stock and Incentive Plan

     The Company has adopted a Stock Award and Incentive Plan
(the "Plan"), which provides for grants of incentive and non-qualified stock
options, 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 have a term not in excess of ten years. The
exercise price for stock options will not be less than 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.
     The following table summarizes stock option and
restricted stock activity for the Plan:

Note 22.  Accounting for Asset Retirement Obligations

     SFAS No. 143, "Accounting for Asset Retirement
Obligations," establishes the financial accounting and reporting for obligations
associated with the retirement of long-lived assets and the associated asset
retirement costs. The Company records asset retirement obligations in which the
Company will be required to retire tangible long-lived assets. These are
primarily related to its PCC satellite facilities and mining operations. The
Company has also applied the provisions of FIN 47 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
contractual or legal 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 December 31, 2007:

     During the fourth quarter of 2007, the Company recognized a business
interruption insurance recovery gain of $3.0 million related to Hurricane Ivan
in 2004.
     During the first quarter of 2006, the Company recognized
an insurance settlement gain of $1.8 million, net of related deductible, for
property damage sustained at one of our facilities in 2004 as a result of
Hurricane Ivan. Claims submitted to the insurance carrier for damages related to
a combination of replacement costs for fixed assets and reimbursement of
expenses associated with the clean-up and repairs at the facility. The insurance
settlement gain related to the reimbursement of replacement costs for fixed
assets in excess of the net book value of such assets.

     During the fourth quarter of 2005, the Company
recognized a litigation settlement gain of $2.1 million relating to the
worldwide settlement of its pending commercial and patent litigation with Omya
AG.

Note 24.  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
offering. 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.

Note 25.  Segment and Related Information

     Operating segments are defined as components of an
enterprise about which separate financial information is available that is
evaluated regularly by the chief operating decision maker in deciding how to
allocate resources and in assessing performance. The Company's operating
segments are strategic business units that offer different products and serve
different markets. They are managed separately and require different technology
and marketing strategies.
     The Company has two reportable segments: Specialty
Minerals and Refractories. The Specialty Minerals segment produces and sells
precipitated calcium carbonate and lime, and mines, processes and sells the
natural mineral products limestone and talc. This segment's products are used
principally in the paper, building materials, paints and coatings, glass,
ceramic, polymers, food, automotive, and pharmaceutical industries. The
Refractories segment produces and markets monolithic and shaped refractory
products and systems used primarily by the steel, cement and glass industries as
well as metallurgical products used primarily in the steel industry.
     The accounting policies of the segments are the same as
those described in the summary of significant accounting policies. The Company
evaluates performance based on the operating income of the respective business
units. Depreciation expense related to corporate assets is allocated to the
business segments and is included in their income from operations. However, such
corporate depreciable assets are not included in the segment assets.
Intersegment sales and transfers are not significant.
     Segment information for the years ended December 31,
2007, 2006 and 2005 was as follows:

equity, and cash flows for each of the years in the three-year period ended
December 31, 2007. In connection with our audits of the consolidated financial
statements, we also have audited the related financial statement schedule. These
consolidated financial statements and financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements and financial statement
schedule based on our audits.
We conducted our audits in accordance with the
standards of the Public
Company Accounting Oversight Board (United
States). Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements
referred to above present fairly, in all material respects, the financial
position of Minerals Technologies Inc. and subsidiary companies as of December
31, 2007 and 2006, and the results of their operations and their cash flows for
each of the years in the three-year period ended December 31, 2007, in
conformity with U.S. generally accepted
accounting principles.
Also in our opinion, the related financial statement schedule, when considered
in relation to the consolidated financial statements taken as a whole, presents
fairly, in all material respects, the information set forth therein.

As discussed in the notes to the consolidated financial
statements, effective January 1, 2007, the Company adopted FASB Interpretation
No. 48, "Accounting for Uncertainty in Income Taxes." In addition, effective
January 1, 2006, the Company adopted Statement of Financial Accounting Standards
("SFAS") No. 123R, "Share-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." Also as discussed in the notes to the consolidated financial
statements, effective December 31, 2006, the Company adopted SFAS No. 158,
"Employers' Accounting for Defined Benefit Pension and Other Post Retirement
Plans - An Amendment of FASB Statements No. 87, 88, 106, and 132(R)."

We also have audited, in accordance with the standards of the
Public Company Accounting Oversight Board (United States), Mineral Technologies
Inc. and subsidiary companies' internal control over financial reporting as of
December 31, 2007, based on criteria
established in Internal Control - Integrated Framework issued by
the Committee of Sponsoring Organizations of the Treadway Commission (COSO),
and our report dated February 27, 2008 expressed an unqualified opinion on the
effectiveness of the Company's internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders

Minerals Technologies Inc.:
We have audited Minerals Technologies Inc. and subsidiary
companies' internal control over financial reporting as of December 31, 2007,
based on criteria established in Internal Control - Integrated Framework issued
by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
Minerals Technologies Inc. and subsidiary companies' management is
responsible for maintaining effective internal control over financial reporting
and for its assessment of the effectiveness of internal control over financial
reporting, included in the accompanying Management's Report on Internal Control
Over Financial Reporting. Our responsibility is to express an opinion on the
Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of
the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether effective internal control over financial reporting was maintained in
all material respects. Our audit included obtaining an understanding of internal
control over financial reporting, assessing the risk that a material weakness
exists, and testing and evaluating the design and operating effectiveness of
internal control based on the assessed risk. Our audit also included performing
such other procedures as we considered necessary in the circumstances. We
believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a
process designed to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external
purposes in accordance with generally accepted accounting principles. A
company's internal control over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in
accordance with generally accepted accounting principles, and that receipts and
expenditures of the company are being made only in accordance with
authorizations of management and directors of the company; and (3) provide
reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use, or disposition of the company's assets that could have a
material effect on the financial statements.

Because of its inherent limitations, internal control over
financial reporting may not prevent or detect misstatements. Also, projections
of any evaluation of effectiveness to future periods are subject to the risk
that controls may become inadequate because of changes in conditions, or that
the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Minerals Technologies Inc. and subsidiary
companies maintained, in all material respects, effective internal control over
financial reporting as of December 31, 2007, based on criteria established in
Internal Control - Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO).

We also have audited, in accordance with the standards of the
Public Company Accounting Oversight Board (United States), the consolidated
balance sheets of Minerals Technologies Inc. and subsidiary companies as of
December 31, 2007 and 2006, and the related consolidated statements of
operations, shareholders' equity, and cash flows and related financial statement
schedule for each of the years in the three-year period ended December 31, 2007,
and our report dated February 27, 2008 expressed an unqualified opinion
on those consolidated financial statements and financial statement schedule.

Management's Report On Internal Control Over Financial Reporting

     Management of Minerals Technologies Inc. is responsible
for the preparation, integrity and fair presentation of its published
consolidated financial statements. The financial statements have been prepared
in accordance with U.S. generally accepted accounting principles and, as such,
include amounts based on judgements and estimates made by management. The
Company also prepared the other information included in the annual report and is
responsible for its accuracy and consistency with the consolidated financial
statements.

     Management is also responsible for establishing and
maintaining effective internal control over financial reporting. The Company's
internal control over financial reporting includes those policies and procedures
that pertain to the Company's ability to record, process, summarize and report
reliable financial data. The Company maintains a system of internal control over
financial reporting, which is designed to provide reasonable assurance to the
Company's management and board of directors regarding the preparation of
reliable published financial statements and safeguarding of the Company's
assets. The system includes a documented organizational structure and division
of responsibility, established policies and procedures, including a code of
conduct to foster a strong ethical climate, which are communicated throughout
the Company, and the careful selection, training and development of our people.

     The Board of Directors, acting through its Audit
Committee, is responsible for the oversight of the Company's accounting
policies, financial reporting and internal control. The Audit Committee of the
Board of Directors is comprised entirely of outside directors who are
independent of management. The Audit Committee is responsible for the
appointment and compensation of the independent registered public accounting
firm. It meets periodically with management, the independent registered public
accounting firm and the internal auditors to ensure that they are carrying out
their responsibilities. The Audit Committee is also responsible for performing
an oversight role by reviewing and monitoring the financial, accounting and
auditing procedures of the Company in addition to reviewing the Company's
financial reports. The independent registered public accounting firm and the
internal auditors have full and unlimited access to the Audit Committee, with or
without management, to discuss the adequacy of internal control over financial
reporting, and any other matters which they believe should be brought to the
attention of the Audit Committee.

     Management recognizes that there are inherent
limitations in the effectiveness of any system of internal control over
financial reporting, including the possibility of human error and the
circumvention or overriding of internal control. Accordingly, even effective
internal control over financial reporting can provide only reasonable assurance
with respect to financial statement preparation and may not prevent or detect
misstatements. Further, because of changes in conditions, the effectiveness of
internal control over financial reporting may vary over time.

     The Company assessed its internal control system as of
December 31, 2007 in relation to criteria for effective internal control over
financial reporting described in "Internal Control - Integrated Framework"
issued by the Committee of Sponsoring Organizations of the Treadway Commission.
Based on its assessment, the Company has determined that, as of December 31,
2007, its system of internal control over financial reporting was effective.

     The consolidated financial statements have been audited
by the independent registered public accounting firm, which was given
unrestricted access to all financial records and related data, including minutes
of all meetings of stockholders, the Board of Directors and committees of the
Board. Reports of the independent registered public accounting firm, which
includes the independent registered public accounting firm's attestation of the
effectiveness of the Company's internal control over financial reporting are
also presented within this document.

•	Building Decontamination. We have completed the investigation of building contamination and submitted a report characterizing the contamination. We are awaiting review and approval of this report 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 are still conducting investigations of potential groundwater contamination. To date, the results of investigation indicate that there is some oil contamination of the groundwater. We are conducting further investigations of the groundwater.
•	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.

•	The Company has exited its Synsil^® Products product line and will sell its Synsil^® Products manufacturing facilities in Chester, South Carolina, Cleburne, Texas, and the customer sampling facility in Woodville, Ohio. This resulted in an impairment of assets charge of approximately $42.2 million, which is included in discontinued operations.
•	We have concluded that Synsil®, in its current product form, is not suitable to penetrate a significant portion of the market previously envisioned. The initial success achieved in certain market segments proved unsustainable at higher operating/fill rates for major glass market segments.

•	The company will realign these product lines, which consists of four mines and processing facilities in the United States; two plants in the Midwest that process imported ores; and the Specialty PCC product line.
•	The two Midwest plants in Mt. Vernon, Indiana, and Wellsville, Ohio, acquired in 2002, which primarily process Chinese talc ores, will be held for sale and are included in discontinued operations. This realignment will result in a change of direction from diversified product lines that included processing imported ore to an integrated "mine to market" strategy. The Company recorded impairment of assets charges of approximately $5.9 million related to the realignment of the Processed Minerals product line, of which $4.6 million was included in discontinued operations.
•	Going forward, four fully integrated operations will be the focus of the "mine to market" strategy, three of which produce ground calcium carbonate, primarily for the construction and automotive sectors. These are in Adams, Massachusetts; Canaan, Connecticut; and Lucerne Valley, California. The fourth facility mines and produces talc in Barretts, Montana.

•	The company will modify the marketing strategy for its coating PCC products and will convert from a merchant business model to a satellite business model for coating PCC, one that has proven successful in the past. This has resulted in consolidation of the coating PCC operations in Europe with the closure of our PCC merchant facility in Hermalle, Belgium.
•	Current commercial customers have been transferred to our coating PCC merchant facility in Walsum, Germany, which will also focus on supporting market development activities for the satellite PCC program. The Company recorded an impairment of assets charge related to the coating development program of approximately $58.7 million.

•	Increasing our sales of PCC for paper by further penetration of the markets for paper filling at both freesheet and groundwood mills;
•	Development of the filler-fiber composite program, to increase the fill-rate for uncoated freesheet paper, which continues to undergo large-scale paper machine trials.
•	Further development of the Company's PCC products, filling and coating, for use in the satellite model.
•	Development of unique calcium carbonates used in the manufacture of novel biopolymers, an emerging market opportunity.
•	Rapid deployment of value-added formulations of refractory materials that not only reduce costs but improve performance.
•	Leverage the Company's expertise in crystal engineering, especially in helping papermakers customize PCC morphologies for specific paper applications.
•	Continuing our penetration in emerging markets through our manufacturing facility in China and our recent acquisition in Turkey, both within the Refractories segment.
•	Further increasing market penetration in the Refractories segment through development of high-performance products and equipment systems.

•	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 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;
•	Our filler-fiber composite technology continues in development through customer trials, but has yet to be proven on a long-term commercial scale.
•	We are subject to cost fluctuations on raw materials, including shipping costs, particularly for magnesia and alumina imported from China;
•	Our Processed Minerals and Specialty PCC product lines are highly influenced by the domestic building and construction markets.
•	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.

•	Continued development and potential commercial introduction of filler-fiber composite technology for the paper industry to increase the fill-rates of uncoated freesheet paper.
•	Increase market penetration of PCC by expanding the satellite model.
•	Emphasize higher value specialty products and application systems to increase market penetration in the Refractories segment.
•	Expand regionally into emerging markets where we have a limited presence and increase our presence in regional markets where the manufacturing of paper and steel is shifting, particularly to China and Eastern Europe.
•	Development of unique calcium carbonates used in the manufacture of biopolymers, an emerging market opportunity.
•	Continue to improve our cost competitiveness in all product lines.
•	Explore selective acquisitions to complement our existing businesses.

•	significant under-performance relative to historical or projected future operating results;
•	significant changes in the manner of use of the acquired assets or the strategy for the overall business;
•	significant negative industry or economic trends.

	When we determine that the carrying value of intangibles, long-lived assets or goodwill may not be recoverable based upon the existence of one or more of the above indicators of impairment, we principally measure any impairment by our ability to recover the carrying amount of the assets from expected future operating cash flow on a discounted basis. Net intangible assets, long-lived assets, and goodwill amounted to $576.6 million as of December 31, 2007.
•	Accounting for income taxes: As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating current tax expense together with assessing temporary differences resulting from differing treatments of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in the consolidated balance sheet. We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income, and to the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we must include an expense within the tax provision in the Consolidated Statements of Operations.
	The Company accounts for uncertain tax positions in accordance with FASB Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" ("FIN 48"), an interpretation of FASB Statement No. 109 ("SFAS 109"). The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous. As such, we are required to make many subjective assumptions and judgements regarding our income tax exposures. Interpretations of and guidance surrounding income tax laws and regulations change over time. As such, changes in our subjective assumptions and judgements can materially affect amounts recognized in the consolidated balance sheets and statements of operations. See Note 5 to the condensed consolidated financial statements, "Income Taxes," for additional detail on our uncertain tax positions.
•	Pension Benefits: We sponsor pension and other retirement plans in various forms covering the majority of employees who meet eligibility requirements. Several statistical and actuarial models which attempt to estimate future events are used in calculating the expense and liability related to the plans. These models include assumptions about the discount rate, expected return on plan assets and rate of future compensation increases as determined by us, within certain guidelines. Our assumptions reflect our historical experience and management's best judgment regarding future expectations. In addition, our actuarial consultants also use subjective factors such as withdrawal and mortality rates to estimate these assumptions. The actuarial assumptions used by us may differ materially from actual results due to changing market and economic conditions, higher or lower withdrawal rates or longer or shorter life spans of participants, among other things. Differences from these assumptions may result in a significant impact to the amount of pension expense/liability recorded by us follows:
