Dear Shareholders: As your new Chairman and Chief Executive Officer, I am delighted to be taking

over the helm of Minerals Technologies Inc., and am excited about the potential opportunities as well as the challenges that lie
ahead of the company. I, along with MTI’s 2,800 associates, look forward to taking on those challenges and, over time, deliv-
ering to you improved performance, higher returns on capital and, in turn, greater shareholder value. First, I would like to give
you a brief overview of the company’s recent performance track, review the major challenges and opportunities as I see them
today and then discuss the major areas we will focus on going forward. Let’s start with performance. 

Cumulatively, our total shareholder return has underperformed both the Standard & Poors 500 and the S&P Midcap

400 Materials Sector over the past five years. At the same time, our Return on Capital has dropped from 8.6 percent in 2001
to 6.0 percent today—both of which were well below the peak return years of 1998 and 1999 when the company achieved
around 11 percent. 

Our profitability, except for a brief spike in 2004, has remained relatively flat despite a robust compound annual
growth rate of 9.3 percent in revenues over the five-year period. One of the critical issues facing our company has been the
inability to leverage our sales growth into additional profits. For example, operating income increased by a compound rate of
only 1 percent between 2001 and 2006, while net income remained essentially flat. We have averaged an annual increase in
sales of approximately $75 million since 2001, but net income as a percentage of sales has declined from 7.3 percent in that
year to 4.7 percent in 2006. 

MTI’s Cash Flow has been strong, generating $560.5 million from operations in the past five years. However, cumu-
lative Capital Spending has been $464.6 million over the same period, with marginal return to the company. During this peri-
od, the company made substantial investments in PCC for paper coating in Europe, SYNSIL® Products and filler-fiber compos-
ite materials, which have had a significant negative impact on operating results and returns.

During the course of these five years, we have seen major changes in the industries we serve, primarily paper and

steel. The worldwide paper industry has consolidated and rationalized, resulting in the closing of smaller, less efficient paper
mills and the shutdown of some paper machines, most of which occurred in North America, our largest market. Since 2000,
MTI has closed 10 satellite PCC plants, primarily because of industry consolidation. The steel industry has also undergone an
enormous transformation with steel companies declaring bankruptcies—sometimes more than once—in the early part of the
decade and undergoing consolidation that rivals that of the paper industry.

Increased globalization also occurred during this period as paper and steel companies continued to move to new areas
of the world. Both paper and steel production have increased in Asia, primarily China. At the end of 2006, China was produc-
ing over 418 million metric tons of crude steel, which is more than the five next largest producing nations combined—Japan,
the United States, Russia, South Korea and Germany. Contrast that with the 151 million metric tons China produced in 2001
and you get a clear picture of the magnitude of that growth. In the paper industry, China’s growth in production of printing
and writing paper, which affects MTI the most, has increased from 10.4 million metric tons in 2001 to 15.9 million metric
tons in 2006, a more than 50-percent increase. Graphic paper production, which consists of printing and writing paper and
newsprint, is expected to increase between 3 percent and 3.5 percent annually through 2020. Latin America and Eastern
Europe are also expected to grow significantly in steel and paper production.

Chairman & 
Chief Executive Officer

JOSEPH C. MUSCARI joins Minerals Technologies Inc. after more than 37 years at Alcoa, the world’s largest producer of
aluminum. His most recent position at Alcoa was Chief Financial Officer. Before becoming CFO in January 2006, he was
head of Alcoa’s $3.5 billion Rigid Packaging, Foil and Asia group, a position he assumed in 2004. He also had responsibility
for Alcoa’s businesses and growth strategy in Asia and Latin America, a role he assumed in 2001. He was named an
Executive Vice President of Alcoa in 2002, and was a member of the Executive Council, the Alcoa senior leadership group
that set strategic direction.

Joe Muscari began his Alcoa career in 1969 as an Industrial Engineer. During his early years there, he also held an 
assignment in the Corporate Secretary’s Office in Pittsburgh. In 1979, he began a series of management positions first as
Controller of the Forging Division in Cleveland, then for the Engineered Products Group. Mr. Muscari next became
General Manager of the Powder and Pigments Division in Pittsburgh. In 1986, he was named Director of Alcoa’s IT group
and eventually added responsibility as Quality Director for the Finance group. In 1989, he was promoted to Group Vice
President, The Stolle Corporation, a diversified Alcoa business group located in Ohio.  

2006 Performance MTI’s 2006 performance followed the basic track of the previous four years in terms of delivering good
revenue growth without being able to leverage it into higher overall earnings and improved returns. Worldwide sales for the
full year were $1.059 billion, a 7-percent increase over 2005, and the company’s operating income for the full year 2006 was
$84.9 million, a 5-percent increase over the $81.0 million in 2005. However, Net Income decreased by 6 percent to $50.0
million from $53.3 million in 2005 due to higher interest expense, increased minority interest provisions and liquidation
costs from a discontinued operation. Return on Capital came in at 6.0 percent, slightly below that of 2005’s 6.2 percent.

Sales in the Specialty Minerals segment, which consists of precipitated calcium carbonate (PCC) and Processed
Minerals, increased 7 percent in 2006 to $711.4 million compared with $663.0 million for 2005. Specialty Minerals’
operating income for 2006 was $52.9 million, slightly above that of 2005.

PCC revenue increased 8 percent with an underlying volume increase of 5 percent from $516.3 million in 2005 
to $557.0 million in 2006. However, sales of Specialty PCC, which is used in non-paper applications, increased only 1.4
percent, from $55.6 million in 2005 to $56.4 million in 2006.

Sales of Processed Minerals products increased 5 percent to $154.4 million in 2006 from $146.7 million in 2005. Sales
of SYNSIL® Products, a new composite mineral for the glass industry, increased 58 percent to $10.4 million in 2006 from $6.6
million in 2005 and accounted for more than half of Processed Minerals’ revenue increase. Despite this growth in sales, the
SYNSIL® Products program continues to operate at a significant loss; operating losses increased approximately $2.5 million.

The Refractories segment was a bright spot for the company in 2006 as sales were $347.9 million, a 6-percent
increase over the $327.8 million in 2005 and operating income of  $32.0 million, was 13-percent higher than 2005.

Looking Forward  MTI has significant challenges and opportunities. The company is operating from a profitable base and
has a platform for growth. We need, however, to determine how to be more profitable and to improve our returns. That’s a
positive challenge and it’s something that I believe the company is capable of—growing profits to higher levels and at faster
rates than it has in the past. 

MTI is well-positioned globally to meet the rising demand we see in emerging markets—China, Latin America, Eastern

Europe. Our technological expertise will enable us to quickly transfer products and solutions to new customers around the
globe. At the same time, however, because of intense and increasing competition, one of my priorities will be to improve
operational and global supply chain efficiencies and effectiveness, which will include a greater emphasis on cost reduction.

Consolidation in the industries we serve, and possible future consolidations, will continue to place greater pressure
on our ability to price our products so that we receive fair value for the value we provide. It will be critical that we aggres-
sively tap into MTI’s DNA of Research and Development to develop and commercialize improved products and services.  

There are four key areas the company will focus on as we go forward:
Profitable growth: We must improve our return on capital as we grow. We must—as quickly as possible—attain
returns that are greater than our cost of capital. To do that, we will focus on making future capital spending as effective and
efficient as possible. MTI will focus on working capital efficiencies, global sourcing opportunities, value pricing, and selec-
tive acquisitions that can enhance our global positions, products and technologies.

In 1992, Mr. Muscari moved to Japan as President of Alcoa Asia accountable for Operations and
Business Development as well as Sales and Marketing services for the Asian region. He established
Alcoa’s first major operation in China and developed the company’s long-term strategy there. He
returned to Pittsburgh in 1997 as Vice President of Audit, and, subsequently, was elected Vice
President, Environment, Health & Safety, Audit and Compliance, a new position. In 2001, he
once again took on a newly created business as Group President Asia and Latin America, in
charge of operations and growth projects in the two regions.

Mr. Muscari graduated cum laude in 1968 with a degree in industrial engineering from the New
Jersey Institute of Technology and earned an M.B.A. degree from the University of Pittsburgh in
1969. In 1994, he received an honorary Doctor of Law degree from Salem-Teikyo University. Mr.
Muscari is also a board member of CHALCO, the Aluminum Corporation of China.

Product innovation: Research and Development, which has been a core competency of the company, will need to be

become better focused and more effective in developing and commercializing new products. Accelerating commercialization
of our three current major innovations—SYNSIL® Products for glass manufacturing, PCC for paper coating and filler-fiber
composites for paper filing—will continue to be key priorities for the company, but we will also emphasize new applications
and improvements to our existing product lines. The Refractories segment, for example, has developed incremental product
improvement as an integral part of its strategy. 

Operational Excellence: Continuous improvement in all aspects of the company’s operations built on a platform of

process stability and control, Daily Management, TPM—Total Productive Maintenance—and the involvement of all MTI
employees will be our target condition for how we operate. The relentless focus on waste elimination in delivering our prod-
ucts and services to our customers will be critical to achieving higher levels of return.

Customers: One of MTI’s principles is: “We make money by helping our customers make money.” Having an
imbedded, holistic approach to continuously improving and constantly working at satisfying customers is a key ingredient
to being a high-performing company. We will emphasize a clear and focused dedication to help our customers improve their
profitability by bringing them new products and applications faster. 

In the next several months, I will be visiting many of MTI’s customers and employees to gain a clearer understanding

of our processes and where they can be improved. I will place particular emphasis on research and development, capital
spending, safety, cost, and productivity.

I joined the Board of Directors of Minerals Technologies two years ago, and during that time I gained a basic under-
standing of our businesses. I had no intention of leaving Alcoa, where I had spent my entire career, but began to consider it
seriously when other members of the MTI Board approached me about running this company. I recognized that increasing
shareholder value would be a challenge, but not an insurmountable one because MTI has a solid core of hard-working,
dedicated people and innovative products. I also welcomed the challenge during this stage of my career to lead a company
with the growth potential that MTI has through providing new product solutions to “basic” industries.

MTI’s values, however, were the major factor that tipped the balance for me. I believe that solid values are a founda-
tion for any business, that they differentiate one enterprise from the next. And, I recognized that Minerals Technologies was
a very good match for both the value system I had been operating in professionally, as well as my own personal values. This
strong foundation provides us the leverage to focus on improving our return to shareholders. 

There is a great deal of work ahead of us, but with the support of our shareholders, customers, suppliers and
employees, I am confident that we will move our fine company to the levels of profitability that it is capable of achieving.

Moving with the Market

A simple truth: Conditions in the North American business landscape have changed the
face of MTI’s client industries through bankruptcies, consolidation and erratic business

cycles. The volatility of domestic steel is a long, too-familiar story. Meanwhile, the

embattled U.S. paper industry for a decade has tried every means of improving operat-

ing efficiencies and propping up earnings in a culture inexorably gravitating towards

electronic media. Though profits have recently stabilized, that stability has come at a

high cost: bankruptcies and plant closings. The inevitable consolidations also have vested

the power in fewer hands, resulting in increased buying leverage.

“The two major process industries MTI primarily serves—paper and steel—are in

the midst of a shift to global production and marketing, providing as they evolve some

of the most promising opportunities for business development,” says Joseph C. Muscari,

Chairman and Chief Executive Officer of Minerals Technologies. “For MTI, this means

that continued growth and higher returns on investment depend upon successful

deployment of resources to such regions as Asia, Europe, and Latin America. It also

means that MTI must leverage itself across regions and countries faster and more

effectively to serve customers than in the past—a significant challenge—but one the

company is up to.”

Paper PCC

There can be no overstating the explosive-
ness of the Chinese economy: Among
major world economies, it is the fastest
growing. China’s GDP expanded by 10.7
percent in 2006, and is expected to be at a
similar level in 2007. 

Given such growth, it’s no surprise
that China would emerge as a key player
in paper production and consumption.
While elsewhere, demand for paper
remains somewhat lackluster heading into
2007, the Chinese paper industry boasts
year-to-year growth that parallels the brisk
double-digit expansion of China’s GDP. By
2010, according to RISI, an information
provider for the worldwide forest products
industry, papermakers in China likely will
be producing more than 20 million metric
tons of printing and writing paper from a
2006 base of about 16 million tons. By
comparison, North America produced
29.4 million tons of printing and writing
paper in 2006 and is projected to produce
29.1 million tons of the same grades in
2010, while Western Europe produced
37.7 million tons in 2006 and is projected
to reach 39.9 million tons by 2010.

Hence, the rationale behind the
Company’s early entry into China in
1999, when it constructed its first satellite
PCC plant in Dagang as part of a joint
venture between Specialty Minerals Inc.
(SMI) and Asia Pulp & Paper Company
(China) Pte. Ltd. (APP). In 2005, the
company followed the market by con-
structing a pair of large satellite PCC
plants for APP at Suzhou and Zhenjiang.
The Suzhou facility produces filler only,
while the Zhenjiang plant manufactures
PCC for both filler and coating. Each of
these plants produces approximately four
units of PCC annually, a unit representing

8

between 25,000 and 35,000 tons. The
Zhenjiang plant was designed to be
expandable with APP’s increasing require-
ments. The facilities bring SMI’s total
worldwide satellite network to 51 plants,
and mark the Asian unveiling of the
Opacarb® A40 PCC family of coating
products—a premier coating-grade calci-
um carbonate that offers sub-micron parti-
cle size and narrow particle-size distribu-
tion. Though ground calcium carbonate
(GCC) and kaolin clays hold market share
in paper coatings, Opacarb offers
improved brightness and gloss versus stan-
dard carbonates. This allows papermakers
to reformulate their coating, thereby
reducing overall coating cost while main-
taining quality. This gives SMI a competi-
tive advantage in a sector that offers
dynamic growth potential: An estimated
19 million tons of mineral pigment is used
in coating paper worldwide. 

Looking beyond manufacturing, a
technological/Research & Development
presence in the region has become a com-
petitive necessity. For the first time in
2006, China itself outspent every nation
on total R&D except the U.S., investing
an estimated $135 billion, narrowly edging
out Japan for second place. The MTI
response takes the form of its Asian
Technical Center, located on the same site
as the new MINTEQ refractories plant in
Suzhou. This new technical facility actual-
ly is one of the outgrowths of the compa-
ny’s earlier major effort in R&D globaliza-
tion—SMI’s Technical Center in Kaarina,
Finland, which services all of Europe. 

“Ten years ago we had a vision: to set

up a state-of-the-art research facility in
Finland, whose economy is heavily depend-
ent on paper and whose technical expertise

is head of the class,” says Robert Moskaitis,
Vice President of Strategic Research, MTI.
“At first we had a modest facility that we
supported from the U.S. As that market
grew, the facility grew with it. Today,
Kaarina becomes the template for the Asian
center. We’ll continue to staff and support
Asia R&D as it moves towards self-suffi-
ciency.” This “cloning” approach to R&D
facilities investment allows for a lower level
of investment and risk while still achieving
desired results.

Adds Kenneth L. Massimine, Senior

Vice President & Managing Director,
Paper PCC, “We are committed to estab-
lishing a technological base, and to deliver-
ing the most advanced products with the
highest customer value in these emerging
markets.”

Another approach to globalization
the company has taken is to establish a
merchant business model to serve one of
the fastest growing regions for paper coat-
ing pigments. In SMI’s merchant facility
for the production of coating-grade PCC
at Walsum, Germany, the Company has
established a logistically ideal foothold in
the European market for high quality pub-
lication and graphic-arts papers. Walsum’s
annual capacity of 125,000 tons, expand-
able to a potential half-million tons, brings
SMI’s total European presence to a dozen
plants with a capacity to produce more
than one million tons of various types 
of PCC. 

“We’re also focusing on opportuni-
ties in Latin America—Brazil in particu-
lar,” says Massimine. “By taking these
steps, we will strengthen our competitive
position in areas of high-growth potential.”

to delivering the most advanced products with the highest 
customer value in these emerging markets.”

Refractories Growth Markets

Certainly, all eyes also look eastward to
China when it comes to sheer breadth of
marketplace potential in steel.

A story as dramatic as China’s recent
domination of the steel industry probably
has not been written since the dawn of the
Industrial Revolution itself. In 2006,
China’s steel production of more than 418
million tons—an increase of 65 million
tons over 2005—constituted about 35 per-
cent of the total global steel output of 1.2
billion tons. China also led the world in
steel consumption, at 374 million tons,
and exports, at 49.2 million tons, the latter
figure about 92 percent above the previous
year’s. Yet, the most telling statistic may be
this: There are now hundreds of steel com-
panies doing business in China today.
China will likely set the pace for the global
market in this key infrastructure commod-
ity for the foreseeable future. 

And with steel accounting for more

In October, the Company completed

than half the refractory materials con-
sumed worldwide, the opportunities—and
strategic imperatives—are clear.

MINTEQ’s most visible response 

is its refractory manufacturing plant at
Suzhou, Jiangsu Province, now operational
with a capacity to produce about 100,000
tons of monolithic refractory materials.
Surrounded by a cluster of 14 modern
steel mills, the plant sits just 50 miles west
of where two thriving economic-develop-
ment belts meet at Shanghai, also MTI’s
Asian headquarters. 

The Asian sector as a whole abounds
with possibility. Indian steel consumption
is on the rise, albeit from a much lower
baseline. Japan and South Korea continue
to record modest growth, thanks to up
ticks in ship building, cars, and industrial
machinery. Steel making is accelerating
once again in Eastern Europe, led by
Russia, which, notably, has expanded
Electric Arc Furnace capacity, with more
than 70 million tons now in place. 

its $30 million acquisition of ASMAS, a
rapidly growing Istanbul-based producer of
refractories. Though Turkey is a meaning-
ful steel producer in its own right (22 mil-
lion tons), ASMAS gives MINTEQ an
immediate presence in a region that is cru-
cial to success in tomorrow’s refractories
business: the Middle East and the rest of
Eastern Europe. “The ASMAS acquisition
is consistent with MINTEQ’s strategy of
direct investment into regions where the
steel industry is expanding,” says Alain F.
Bouruet-Aubertot, Senior Vice President
and Managing Director, MINTEQ
International. 

Adds John Damiano, Vice President
of Research and Development, MINTEQ,
“If you look at the growth markets from a
refractory standpoint, MINTEQ offers
many value-added enhancements to our
customers. In effect we become their busi-
ness partner, extending the technological
horizons of their operations.”

North America Remains Important

innovative aluminum applications. We
have proven that monolithics are a better
value than bricks and we will continue our
effort to supplant the use of brick through
our technological strength.”

Nowhere, however, is the vitality of

MTI’s ongoing commitment to North
America clearer than in Performance
Minerals’ activities in the domestic auto
and consumer polymers industry. “The
bulk of our business is in North America,”
says D. Randy Harrison, Vice President
and Managing Director, Performance
Minerals. “For us, the movement is less
about geography than shifting with the
needs of our end-users, as automotive and
consumer packaging applications them-
selves evolve and diversify.”

Case in point: instrument panels and

car interiors. Once bolted together out of
metals and hard, unaesthetic plastics,
today’s interiors benefit from next-genera-
tion processes and materials. Performance
Minerals’ talc plays a key role here, sup-
porting the creation of one-piece modular
components for instrument panels, con-
soles and other interior pieces; these fea-
ture a softer, richer, more textured look,
with superior durability.

The average car today contains 311
pounds of plastic, but within a few years
that figure is likely to exceed 400 pounds.
It’s a trend driven most obviously by fuel
efficiency, but no less important is the
impetus to standardize and simplify multi-
ple design options. “Metal parts do not
have plastic’s design possibilities,” says
Harrison. “You can only bend metal in a
limited number of dimensions, whereas
plastic can be fabricated into a myriad of
shapes. We’re enabling them to make that
transition while also maximizing their 
performance and reducing costs.”

Underlying all of these initiatives 

is an industry-leading plastics lab in
Bethlehem, Pennsylvania, built from the
ground up following the 2004 devastation
of the original Easton, Pennsylvania, lab
after Hurricane Ivan. The new lab offers
twice the usable space, and greater than 80
percent of its equipment is brand new. “As
a business priority, we made a major strate-
gic investment in the lab and back it with
the hiring of the best plastics people avail-
able,” says Harrison. “Customers who have
visited the lab have been very impressed by
both the facilities and the people manag-
ing our R&D efforts.”

It’s important to emphasize that taking full
advantage of global opportunities does not
mean abandoning North America.

“North America will always be an
important marketplace for PCC,” says
Massimine. “We’re well positioned at
world-class paper mills so that when new
technology is commercialized, we’ll be able
to move rapidly on those developments.” 
Similarly, in steel, while downturns

in the U.S. market have depressed the total
figures for North America, current projec-
tions do call for steel utilization to rise sig-
nificantly in Canada and Mexico. More to
the point, says Damiano, “Just because we
may not see another basic oxygen furnace
built in the U.S., that doesn’t mean we’re
going to sit back and take what the status
quo gives us.” MINTEQ continues to
develop products that drive the market by
offering the customer a compelling value
equation. The focus is primarily on select
components, like ladles, that represent the
most expensive aspects of steel making,
and on safer, more sophisticated approach-
es to cost containment during routine
maintenance. “We’re selling Scantrol® laser
refractory measuring system units both for
ladles and the electric arc units,” says
Damiano. “We’re still developing our hot
shotcrete materials, which permit mainte-
nance without significant downtime.
We’ve also been given the go-ahead for

Innovation is Key

The plastics lab embodies a core aspect of
MTI that has not changed despite market
dislocations. Though conditions today
require that we move with our markets, an
equally vital part of our business model
has always been a commitment to bringing
MTI’s vision and technological leadership
to help shape the evolution of constituent
industries. We will continue to introduce
products and processes that provide
disruptive technologies to the industries
we serve. To use just two examples:

MTI’s family of SYNSIL® Products is
another story of breakthrough poten-
tial that has just begun to be commer-
cialized. There is no question that
SYNSIL® belongs in a unique category:
products that can potentially be indus-
try-transforming. SYNSIL® promotes
faster melting and integration of raw
materials at lower temperatures, pro-
viding the glass maker with significant-
ly increased throughput while extend-
ing furnace life, reducing energy con-
sumption and emissions, and affording
unprecedented flexibility in adjusting
the once-constant variables of glass
making to individual needs. New

The target fill-rate is above 30 percent
PCC filler by weight of the paper as
compared to typical current fill-rates of

and 18 to 21 percent in Europe.
Although the specific value proposition
here will be customer-dependent, we
estimate that filler-fiber composites
potentially offer value to the majority

EXECUTIVE SUMMARY

2006 proved to be a difficult year for the Company. Although we achieved many milestones such as exceeding $1

billion in sales and sold more than 4.0 million tons of PCC, we were unable to leverage our 7% increase in sales to
improved operating income performance. This was primarily because of unrecovered raw material and energy cost
increases, paper mill and paper machine shutdowns, and weakness in our end-use markets, particularly in the fourth
quarter. At the same time, we continued to invest heavily in development programs such as PCC for paper coating in
Europe, our SYNSIL® Products for the glass industry, and filler-fiber composites for paper filling. Worldwide net sales
for 2006 grew 7% over the prior year from $991 million to $1.059 billion. Foreign exchange had a favorable impact
on sales of less than 1 percentage point of growth. Operating income for the full year 2006 increased 5% to $84.9
million from $81.0 million in the prior year.  Operating income represented 8.0% of sales in 2006 and was 8.2% of
sales in 2005. Income from continuing operations decreased 2% to $51.6 million from $52.7 million in the prior
year. Net income for the full year 2006 declined 6% to $50.0 million from $53.3 million in 2005.

Our operating income and net income has been affected by a number of factors over the past year. The positive

factors affecting the operating income and net income were primarily attributable to the following:

• Increased profitability in the refractory products and systems product line, particularly in North America and
Europe, due to strong demand through the first nine months of the year and lower costs achieved through
product reformulations;

• Improved operations at our new satellite PCC facilities in China; 
• Increased worldwide demand for PCC in all regions, and volume growth from expansions of existing PCC

facilities in Europe; and

• Royalty income and reduced litigation expenses from the settlement of patent litigation. The Company will

receive additional royalty income of approximately $1.1 million per annum through 2009.

This growth was partially mitigated by the following factors:

• Unrecovered cost increases in the PCC product line due to the delayed pass-through of lime cost increases;
• Paper mill and paper machine shutdowns affecting several satellite PCC facilities;
• Operating losses in our SYNSIL® Products line primarily due to initial startup costs associated with our

manufacturing facility in South Carolina;

• Unrecovered energy cost increases and significant weakness in the end-use markets during the fourth quarter

of 2006 in the Processed Minerals and Specialty PCC product lines;

• Increased compensation expense related to the adoption of SFAS No. 123R; 

16

 
Management’s Discussion and Analysis
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

• Decreased margins in the metallurgical product line; and
• During the fourth quarter of 2006, we also recognized a loss from discontinued operations of approximately $1.6

million related to foreign currency translation losses arising from the liquidation of our investment in Israel.

The net effect of the aforementioned factors resulted in operating income growth of approximately 5% over 2005,

and a decline in net income of approximately 6% from 2005.

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;

• Consolidations in the paper and steel industries concentrate purchasing power in the hands of fewer cus-

tomers, increasing pricing pressure on suppliers such as Minerals Technologies Inc.;

• Most of our Paper PCC sales are subject to long-term contracts that may be terminated pursuant to their

terms, or may be renewed on terms less favorable to us;

• We are subject to cost fluctuations on raw materials, including shipping costs, particularly on magnesia and talc

imported from China;

• We have experienced increased energy costs in both of our business segments that we may not  be able to pass

through to our customers; 

• Although the SYNSIL® Products family has received favorable reactions from current and potential customers,
this product line is not yet profitable. To date, the introduction of SYNSIL® technology to customers has pro-
gressed more slowly than anticipated, resulting in temporary overcapacity at our facilities. The manufacturing
facilities are strategically located in major market areas for glass making, and we believe our products provide a
suitable value equation for glass manufacturers. However, the commercial viability of this product line cannot
be assured.

• The cost of employee benefits, particularly health coverage, has risen significantly in recent years and contin-

ues to do so; and

• As we expand our operations abroad we face the inherent risks of doing business in many foreign countries,

including foreign exchange risk, import and export restrictions, and security concerns.

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

to us, including: 

• Increasing our sales of PCC for paper by further penetration of the markets for paper filling at both freesheet

and groundwood mills;

• Increasing our sales of PCC for paper coating, particularly from our merchant coating PCC facilities in

Walsum, Germany and Hermalle, Belgium;

• Achieving commercialization of a filler-fiber composite technology for the paper industry through our

continued research and development activities;

• Developing new satellite PCC opportunities;
• Achieving continued market acceptance of the SYNSIL® Products family of composite minerals for the glass industry;
• Continuing our penetration in emerging markets, including our new manufacturing facility in China and our

recent acquisition in Turkey in the Refractories segment; and

• 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 programs.

On July 19, 2005, the Company’s largest customer, International Paper Company (“IP”), announced a general

plan to restructure certain elements of its businesses. As a result, IP sold its coated and supercalendered papers busi-
ness, including four paper mills, to Verso Paper Holdings LLC (“Verso”), an affiliate of Apollo Management LP. The
Company owns and operates PCC satellite facilities at two of those paper mills, Jay, Maine, and Quinnesec, Michigan,
pursuant to PCC supply contracts, which were transferred by IP to Verso in 2006. This transaction has not affected
the Company’s PCC satellite operations or assets.

Management’s Discussion and Analysis
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

On March 21, 2006, the Company temporarily ceased operation of a one-unit satellite PCC facility in Park Falls,
Wisconsin, after the paper company shut down its mill and filed for bankruptcy protection. The Company recorded a
provision for bad debt of approximately $1.0 million in the first quarter of 2006 in connection with this bankruptcy.
The paper mill has since been sold to Flambeau River Papers, LLC and we resumed production pursuant to a long-
term supply contract from our satellite PCC facility in the third quarter.

As expected, in April 2006, the Company ceased operation of a one-unit satellite PCC facility in Hadera, Israel.

Worldwide net sales in 2006 increased 7% from the previous year to $1.059 billion.  Foreign exchange had a favor-
able impact on sales of less than 1 percentage point of growth.  Sales in the Specialty Minerals segment, which includes
the PCC and Processed Minerals product lines, increased 7% to $711.4 million compared with $663.0 million for the
same period in 2005. Sales in the Refractories segment grew 6% over the previous year to $347.9 million.  In 2005,
worldwide net sales increased 8% to $990.8 million from $919.0 million in the prior year.  Specialty Minerals segment
sales increased approximately 7% and Refractories segment sales increased approximately 9% in 2005.

Worldwide net sales of PCC, which is primarily used in the manufacturing process of the paper industry,

increased 8% to $557.0 million from $516.3 million in the prior year. Worldwide net sales of Paper PCC increased
9% to $500.6 million from $460.7 million in the prior year. Paper PCC volumes grew 5% for the full year with vol-
umes in excess of 4.0 million tons. In 2006, worldwide printing and writing paper production totaled approximately
115 million metric tons and increased 2.5% over 2005. Uncoated freesheet, currently our largest PCC market,
increased an estimated 2.1% in 2006. Paper PCC sales growth was achieved in all regions with the largest growth
occurring in Asia. This was primarily attributable to the ramp up of two new satellite PCC plants in China, which
represented approximately 3 percentage points of the volume growth. Worldwide demand for uncoated freesheet and
expansions of satellite PCC facilities in Europe more than offset paper mill and paper machine shutdowns affecting
several satellite PCC facilities. Sales of Specialty PCC grew 1% to $56.4 million from $55.6 million in 2005.

Management’s Discussion and Analysis
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

Worldwide net sales of PCC increased 8% in 2005 to $516.3 million from $480.0 million in the prior year. Net

sales of Paper PCC increased 7% to $460.7 million while Paper PCC volumes grew 4%. In 2005, sales growth was
achieved in all regions, except Latin America, with the largest growth occurring in Europe and Asia where sales vol-
umes grew 7% and 20%, respectively. Sales of Specialty PCC grew 10% in 2005 to $55.6 million from $50.7 million
due to improved volumes, particularly in automotive and health care applications.

Net sales of Processed Minerals products in 2006 increased 5% to $154.4 million from $146.7 million in 2005. Talc
sales increased 8% to $58.5 million from $54.2 million in the prior year. This was primarily attributable to strong global
demand in plastics and health-care related markets. Other Processed Minerals products declined 1% to $85.5 million
from $85.9 million in the prior year. This decline was due to weakness in the residential construction market in the sec-
ond half of 2006. SYNSIL® Products sales increased 58% to $10.4 million due to the initial sales from our new facility in
Chester, South Carolina. Processed Minerals net sales in 2005 increased 6% to $146.7 million from $138.7 million in
2004. This increase was primarily attributable to strong demand in the residential construction markets.

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 to steel and other industrial applications increased 11% to $264.6 mil-
lion from $239.3 million in the prior year. This growth was attributable primarily to increased volume in North
America during the first nine months of 2006 and in Europe throughout the year. In addition, approximately 3 per-
centage points of growth was due to the recent acquisition of a refractory producer in Turkey. Sales of metallurgical
products within the Refractories segment decreased 6% 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. Volumes also
declined, particularly in the fourth quarter in North America, due to weakness in the steel industry.

Net sales in the Refractories segment in 2005 increased 9% to $327.8 million from $300.3 million in the prior
year. Foreign exchange represented approximately 1 percentage point of the sales growth. The sales growth was driven
globally by the metallurgical product line in which sales grew 54% to $88.5 million from $57.3 million. This increase
was attributable to a combination of price increases, due to the substantial escalation in the cost of raw materials for
this product line, as well as volume growth. Sales of refractory products and systems to steel and other industrial
applications decreased 2% to $239.3 million from $243.0 million.

Net sales in the United States increased approximately 5% to $628.4 million in 2006 and represented approximately
60% of consolidated net sales. International sales increased approximately 10% to $430.9 million. This increase was pri-
marily attributable to volume growth in both segments. In 2005, both domestic and international sales increased 8%.

Cost of goods sold in 2006 was 79.1% of sales compared with 78.8% in the prior year.  Our cost of goods sold
grew 7% which had a slightly unfavorable leveraging impact on our sales growth resulting in a 5% increase in produc-
tion margin. This unfavorable leveraging occurred in the Specialty Minerals segment where production margins
increased 1% as compared with 7% sales growth. Margins in this segment were affected by several factors:

• Unrecovered lime cost increases in the PCC product line;
• Paper machine and paper mill shutdowns;
• Production losses in our SYNSIL® Products line primarily due to initial startup costs associated with our new

facility in South Carolina; and

• Unrecovered energy cost increases in the Processed Minerals product line.

Management’s Discussion and Analysis
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

Collectively, these factors had an adverse impact on production margin and operating income, as compared with

the prior year, by approximately $15 million.

These negative factors largely offset the improvements in each of the following areas: 

• Ramp-up of our two new satellite PCC facilities in China;
• Increased demand for PCC, particularly in North America;
• Cost reduction initiatives; and
• Expansions of satellite PCC facilities in Europe.

In the Refractories segment, production margin increased 12% over the prior year as compared with 6% sales
growth. This was primarily due to improved steel industry operating conditions in our primary markets during the
first nine months and cost reduction initiatives through the reformulation of refractory products.

Cost of goods sold in 2005 was 78.8% of sales compared with 76.9% in 2004. Our cost of goods sold grew 11%
which had an unfavorable leveraging impact on our sales growth resulting in a 1% decrease in production margin.
This unfavorable leveraging occurred in both reporting segments. In the Specialty Minerals segment, production
margins declined 3% as compared with 7% sales growth. Margins in this segment were affected by several factors:

• Start-up and ramp-up costs related to the European coating market development program;
• The effects of continuing paper industry capacity rationalization, which lowered demand at several satellite

plants;

• Unrecovered raw material and energy costs; and
• Start-up and ramp-up costs at two new facilities in China.

Marketing and administrative costs increased 6% in 2006 to $106.0 million and represented 10.0% of net sales.
This was primarily due to increased worldwide infrastructure costs and other employee benefits, including increased
stock option expense of approximately $2.3 million relating to the adoption of SFAS No. 123R. We also experienced a
reduction in litigation expenses in 2006 of approximately $3.7 million. In 2005, marketing and administrative costs
increased 8% over 2004 to $100.4 million and represented 10.1% of sales. We incurred higher litigation costs in 2005
to protect our intellectual property. This litigation was settled in the fourth quarter of 2005 resulting in non-operat-
ing income of $2.1 million, while the costs of such litigation were included in marketing and administrative expenses.
Research and development expenses increased 3% in 2006 to $30.0 million and represented 2.9% of net sales. In

2005, research and development expenses remained flat at $29.0 million and also represented 2.9% of net sales. 

We recorded bad debt expenses (recoveries) of $0.4 million, $(0.5) million and $1.6 million in 2006, 2005 and

2004, respectively. In 2006, bad debt expenses increased due to additional customer bankruptcies. In 2005, the
reduction in bad debt charges was primarily related to recoveries of bad debt in excess of provisions. In 2004, the
provision for bad debt was net of recoveries of approximately $2.3 million related to steel company bankruptcies, in
which we had previously written off the related accounts receivable.  

During the fourth quarter of 2005, we recorded a write-down of impaired assets of $0.3 million. The impairment

related to the closure in the first quarter of our satellite facility in Cornwall, Ontario, resulting from the paper mill
shutdown.

In the fourth quarter of 2004, the Company recognized $1.0 million in pre-tax corporate charges related to due

diligence costs from a terminated acquisition effort.

During the fourth quarter of 2003, we restructured our operations to reduce operating costs and improve effi-

ciency.  This resulted in a 2003 restructuring charge of $3.3 million. As part of that restructuring program, we
recorded $1.1 million in additional charges in 2004. The restructuring charges relate to workforce reductions from
all business units throughout our worldwide operations and the termination of certain leases. There were no restruc-
turing costs in 2005 or 2006.

tors affecting production margin. Operating income for the Refractories segment increased 13% to $32.0 million
and was 9.2% of its net sales. This was primarily attributable to increased profitability of refractories products and sys-
tems partially offset by a reduction in profitability in metallurgical products. In addition, this segment benefited from
a pension settlement and curtailment gain of approximately $0.8 million in Asia.

In 2005, income from operations for the Specialty Minerals segment decreased 9% to $52.7 million and was 7.9% of

During the fourth quarter, the Company liquidated its wholly-owned subsidiary in Hadera, Israel, and classified
such business as a discontinued operation. The Company had previously operated a one-unit satellite PCC facility at
this location. The loss from discontinued operations in 2006 of $1.6 million or $0.08 per share was predominantly

OUTLOOK

We are presently experiencing weakness in the primary industries we serve — paper, construction and steel. There

were several paper machine shutdowns that affect our satellite PCC product line as the paper industry continues to
consolidate and rationalize capacity. There is continued softening in the residential construction and automotive
markets and we are faced with low steel-capacity utilization rates in the United States, our largest market. We expect
this weakness to continue into the first half of 2007.

In 2007, we plan to focus on the following growth strategies:

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

China and Eastern Europe.

• Increase market penetration of PCC in paper filling at both freesheet and groundwood mills.
• Increase penetration of PCC into the paper coating market.
• Continue research and development activities for new products, including commercialization of a filler-fiber

composite technology for the paper industry.

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

Refractories segment.

• Continue research and development and marketing efforts for new and existing products, including the 

SYNSIL® Products’ family of composite minerals.
• Continue to improve our cost competitiveness.
• Continue 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.

Management’s Discussion and Analysis
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

The following are notable events that may impact our 2007 performance:
We began operations from our new SYNSIL® Products production facility in the first quarter of 2006 and our oper-

ating losses for this product line increased $2.5 million in 2006, primarily as a result of low volume and start-up
costs. We expect to commence production from a second facility in Cleburne, Texas, in the first quarter of 2007. The
introduction of SYNSIL® technology to consumers has progressed more slowly than anticipated, resulting in temporary
overcapacity at our facilities. The manufacturing facilities are strategically located in major market areas for glass mak-
ing, and we believe our products provide a suitable value equation for glass manufacturers. However, this product line
continues to operate at a significant loss which is expected to continue into 2007 until volumes at our two new facili-
ties increase. The net book value of the long-lived assets at the SYNSIL® facilities were approximately $43.5 million as of
December 31, 2006.

In 2006, we expected a significant acceleration of our coating program with improved volumes from our mer-
chant paper coating PCC facilities in Walsum, Germany and Hermalle, Belgium. While volumes improved, they were
well short of the Company’s expectations and the coating development program in Europe continues to operate at a
significant loss. We expect these operations to improve in 2007. The net book value of the long-lived assets at these
facilities were approximately $50 million as of December 31, 2006.

We began operation of a 100,000-ton capacity refractory manufacturing facility in China during the third quarter

of 2006. We expect this facility to ramp-up in 2007.

In October 2006, we acquired ASMAS, an Istanbul-based Turkish producer of refractories based in Istanbul,
Turkey. This acquisition provides our Refractories segment with an experienced organization and a strong market
position in Turkey, as well as excellent manufacturing capabilities and internal access to our key raw material, magne-
sia. This acquisition 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 require-
ments, 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
generally have been extended, often 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 in 2006 were provided from operations and long-term and short-term financing and were used princi-
pally to fund $85.2 million of capital expenditures, an acquisition of a refractories business for approximately $32.4 mil-
lion, and $53.4 million for purchases of common shares for treasury. Cash provided from operating activities amounted
to $135.6 million in 2006 as compared with $78.5 million in 2005. The increase in cash from operating activities was
primarily due to an improvement of working capital, as compared to the prior year. Our accounts receivables grew at a
lower rate than sales and our days of sales outstanding decreased to 59 days from 60 days in the prior year. Growth in
inventories were primarily attributable to the timing of raw materials purchases and increased inventories resulting from
our recent acquisition. Included in cash flow from operations was pension plan funding of approximately $22.3 million,
$12.9 million and $17.6 million for the years ended December 31, 2006, 2005 and 2004, respectively.

23

Management’s Discussion and Analysis
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

We expect to utilize our cash reserves to support the aforementioned growth strategies.
On October 23, 2003, our Board of Directors authorized our Management Committee, at its discretion, to
repurchase up to $75 million in additional shares over the next three-year period. As of May 21, 2006, the Company
had repurchased 1,286,828 shares under this program at an average price of $58.28 per share.

On October 26, 2005, our Company’s Board of Directors authorized the Company’s Management Committee, at

its discretion, to repurchase up to $75 million in additional shares over the next three-year period. As of December
31, 2006, the Company had repurchased 798,672 shares under this program at an average price of approximately
$52.86 per share.

On January 24, 2007, 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. 

At December 31, 2005, we had $50 million in Guaranteed Senior Notes that matured on July 24, 2006. On
October 5, 2006, the Company issued and sold $75 million aggregate principal of Senior Notes due October 5,
2013, consisting of (a) $50 million aggregate principal amount 5.53% Series 2006- A Senior Notes; and (b) $25 mil-
lion aggregate principal amount Floating Rate Series 2006-A Senior Notes.

We have $186.9 million in uncommitted short-term bank credit lines, of which $73.4 million was in use at
December 31, 2006. In addition, we have an $8.5 million committed short-term bank credit line, all of which was in
use at December 31, 2006. We anticipate that capital expenditures for 2007 should approximate $80 million, princi-
pally 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: 2007 - $2.1 million; 2008 - $7.1 million; 2009 - $4.0 million; 2010 - $4.6 million; 2011 -
$nil; thereafter - $97.6 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, income tax valuation allowances and litigation and environmental lia-
bilities. 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 quar-
ter of 2006 and 2005, 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.

24

Management’s Discussion and Analysis
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

• 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 $0.4 million, $(0.5) million and $1.6 million in 2006, 2005 and 2004,
respectively. The $1.6 million provision in 2004 was net of $2.3 million of bad debt recoveries related to steel cus-
tomer bankruptcies for previously written off accounts receivable. The charges in 2004 were much higher than his-
torical levels and were primarily related to bankruptcy filings by some of our customers in the paper and steel indus-
tries and to additional provisions associated with risks in the paper, steel and other industries. 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 estab-
lished or adjusted.

• 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 impair-
ment 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 trig-
ger 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 $736.4 million as of December 31, 2006.

• 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 estimat-
ing 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 Income.

• Pension Benefits: We sponsor pension and other retirement plans in various forms covering the majority of employ-
ees 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

25

Management’s Discussion and Analysis
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

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:

A one percentage point change in our major assumptions would have the following effects:

• 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.

• Accounting for Stock-Based Compensation: Effective January 1, 2006, the Company adopted the fair value recogni-
tion provisions of SFAS No. 123R, using the modified prospective method. Under this transition method, stock-
based compensation expense was recognized in the consolidated financial statements for stock options granted on and
subsequent to January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of SFAS
No. 123R, and the estimated expense for the portion vesting in the period for options granted prior to, but not vested
as of January 1, 2006, based on the grant date fair value estimated 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 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 judg-
ment 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, 2006, the Company used a volatility of 24.78%.

The expected life calculation was based upon the observed and expected time to post-vesting forfeiture and exer-

cise. For stock options granted during the fiscal year ended December 31, 2006, the Company used a 6.4 year life.

The Company believes the above critical estimates are based upon outcomes most likely to occur, however, were we to
simultaneously increase or decrease the option life by one year and the volatility by 100 basis points, recognized compen-
sation expense would change approximately $0.1 million in either direction for the year ended December 31, 2006.

Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

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” of this Annual Report, beginning on
page 34. 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, uncer-
tainties 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 mind as they consider forward-looking statements and should refer to the dis-
cussion of certain risks, uncertainties and assumptions in Item 1A, “Risk Factors” in the Company’s Annual Report
on Form 10-K. 

INFLATION

Historically, inflation has not had a material adverse effect on us. However, in recent years both business seg-
ments 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 indus-
tries, 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 eco-
nomic 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 September 2006, the FASB issued Statement 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 pronounce-
ments 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 is currently com-
pleting an analysis of the ultimate impact the new pronouncement will have on its financial statements.

In July 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes - An
Interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 clarifies the accounting for uncertainty in income
taxes recognized in an enterprise’s financial statements in accordance with SFAS No. 109, “Accounting for Income

27

Management’s Discussion and Analysis
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

Taxes.” FIN 48 also prescribes a recognition threshold and measurement attribute for the financial statement recogni-
tion and measurement of a tax position taken or expected to be taken in a tax return. In addition, FIN 48 provides
guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and tran-
sition. The provisions of FIN 48 are to be applied to all tax positions upon initial adoption of this standard. Only tax
positions that meet the more-likely-than-not recognition threshold at the effective date may be recognized or contin-
ued to be recognized upon adoption of FIN 48. The cumulative effect of applying the provisions of FIN 48 should be
reported as an adjustment to the opening balance of retained earnings for that fiscal year. The provisions of FIN 48
are effective for fiscal years beginning after December 15, 2006. We are presently evaluating the impact of the adop-
tion of FIN 48 on our consolidated financial statements. 

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 70% of our bank debt bears inter-
est 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 oper-
ations over the next fiscal year.

We do not enter into derivatives or other financial instruments for trading or speculative purposes. When appro-

priate, 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 $4.7 million and $4.2 million of foreign currencies as of December 31, 2006
and 2005, respectively. These contracts mature between February and July of 2007. The fair value of these instruments
at December 31, 2006 and December 31, 2005 was a liability of $0.1 million and $0.2 million, respectively.

Notes to Consolidated Financial Statements
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

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.

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 litiga-
tion 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 and synthetic mineral 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, glass and other manufacturing industries. 

Cash Equivalents and Short-term Investments  The Company considers all highly liquid investments with original maturi-
ties of three months or less to be cash equivalents. Cash equivalents amounted to $4.0 million at December 31, 2006.
Short-term investments consist of financial instruments with original maturities beyond three months. Short-term
investments amounted to $8.4 million and $2.4 million at December 31, 2006 and 2005, 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 experi-
ence 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.

Effective January 1, 2006, the Company has adopted SFAS No. 151, “Inventory Costs - an Amendment of ARB
No. 43, Chapter 4.” As required by this statement, items such as idle facility expense, excessive spoilage, freight han-
dling costs and re-handling costs are recognized as current period charges. In addition, the allocation of fixed pro-
duction overheads to the costs of conversion should be based upon the normal capacity of the production facility.
Fixed overhead costs associated with idle capacity are expensed as incurred. SFAS No. 151 did not have a material
impact on our results of operations during the year ended December 31, 2006.

Property, Plant and Equipment  Property, plant and equipment are recorded at cost. Significant improvements are cap-

italized, 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 purpos-
es. 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 esti-
mated 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 esti-
mates 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 pre-
dominantly 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.

Notes to Consolidated Financial Statements
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

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  As further discussed in Note 23, effective January 1, 2006, the Company has

adopted the consensus of Emerging Issues Task Force (“EITF”) Issue No. 04-06, “Accounting for Stripping Costs
Incurred During Production in the Mining Industry.” Stripping costs are those costs incurred for the removal of
waste materials for the purpose of accessing ore body that will be produced commercially. Stripping costs incurred
during the production phase of a mine are variable costs that are included in the costs of inventory produced during
the period that the stripping costs are incurred.

Accounting for the Impairment of Long-Lived Assets  The Company accounts for impairment of long-lived assets in accor-

dance 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 cir-
cumstances 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 good-
will 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 deter-
mined 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 obli-
gations 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 bor-
rowings, 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.

Derivative Financial Instruments  The Company enters into derivative financial instruments to hedge certain foreign
exchange and interest rate exposures pursuant to 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.

Notes to Consolidated Financial Statements
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

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. 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 accept-

ance. 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. dol-

lars 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 trans-
lated at monthly average exchange rates prevailing during the period. Other foreign currency gains and losses are
included in net income. International subsidiaries operating in highly inflationary economies translate non-mone-
tary 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, 2006, the Company had no international subsidiaries operat-
ing 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 enact-
ed 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 situa-
tions, 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 accompanying financial statements generally do not include a provision for U.S. income taxes on interna-

tional 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  As further discussed in Note 2, effective January 1, 2006, the Company

adopted the fair value recognition provisions of SFAS No. 123R, “Share-Based Payment,” using the modified
prospective method. Under this transition method, stock-based compensation expense was recognized in the consoli-
dated 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,”Accounting for Stock-Based
Compensation.” As provided under the modified prospective method, results for prior periods have not been restat-
ed. Prior to its adoption of SFAS No. 123R, the Company accounted for stock-based compensation using the intrin-
sic value method in APB Opinion No. 25 and recognized no compensation expense in its financial statements. As
permitted by SFAS No. 123, stock-based compensation was included as a pro-forma disclosure in the notes to the
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 com-

mon shares outstanding during the period.

Diluted earnings per share have been computed based upon the weighted average number of common shares outstand-

ing during the period assuming the issuance of common shares for all potentially dilutive common shares outstanding.

Reclassifications  Certain reclassifications were made to prior year amounts to conform with the current year presentation.

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 for 2006 includes $2.3 million pretax compensation costs related to stock option expense as a com-
ponent of marketing and administrative expenses. All stock option expense is recognized in income. The related tax
benefit on the non-qualified stock options is $0.5 million for 2006.

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 years ended

December 31, 2005 and 2004 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, 2006 was approximately 8%.

The weighted average grant date fair value for stock options granted during the years ended December 31, 2006,

2005 and 2004 was $18.97, $24.13 and $20.73, respectively. The weighted average grant date fair value for stock
options vested during 2006 was $20.83. The total intrinsic value of stock options exercised during the year ended
December 31, 2006 was $1.8 million.

The fair value for stock awards was estimated at the date of grant using the Black-Scholes option valuation model

with the following weighted average assumptions for the years ended December 31, 2006, 2005 and 2004:

Expected life (years)

0.32%

The expected term of the options represents the estimated period of time until exercise and is based on historical

experience of similar awards, based upon contractual terms, vesting schedules, and expectations of future employee
behavior. The expected stock-price volatility is based upon the historical volatility of the Company’s stock. The inter-
est rate is based upon the implied yield on U.S. Treasury bills with an equivalent remaining term. Estimated dividend
yield is based upon historical dividends paid by the Company.

total unrecognized stock-based compensation expense related to nonvested stock options was approximately $2.8 mil-
lion, which is expected to be recognized over a weighted average period of approximately three years.

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

Restricted Stock The Company has granted certain corporate officers rights to receive shares of the Company’s com-

mon 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. Upon issuance of the
rights, a deferred compensation expense equivalent to the market value of the underlying shares on the date of the
grant was charged to stockholders’ equity and was being amortized over the estimated average deferral period of
approximately five years. Under the provisions of SFAS No. 123R, the recognition of unearned compensation is no
longer required. Accordingly, in the first quarter of 2006, the balance of Deferred Equity Compensation was reversed
into Additional Paid-in Capital on the Company’s balance sheet. The Company granted 50,300 shares and 36,100
shares for the periods ended December 31, 2006 and 2005, 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, 2006,
there was unrecognized stock-based compensation related to restricted stock of $4.3 million, which will be recognized
over approximately the next four years. The compensation expense amortized with respect to all units was approxi-
mately $1.7 million and $0.9 million for the periods ended December 31, 2006 and 2005, respectively. Such costs are
included in marketing and administrative expenses. 255 restricted stock shares were vested as of December 31, 2006.

NOTE 4. DISCONTINUED OPERATIONS

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 liq-
uidation of its investment in Israel. This loss was predominantly related to the recognition of foreign currency trans-
lation losses previously recognized in accumulated other comprehensive income (loss).

The current portion of the net deferred tax assets is included in prepaid expenses and other current assets.
The Company established a valuation allowance of approximately $0.9 million as of December 31, 2006. This val-
uation allowance relates to net operating loss carryforwards in the state of Ohio where there is an uncertainty regard-
ing their realizability. There was no valuation allowance as of December 31, 2005.

The Company recorded $13.2 million of deferred tax assets arising from tax loss carry forwards which will be
realized through future operations. Carry forwards of approximately $1.8 million expire over the next 15 years, and
$11.4 million can be utilized over an indefinite period.

The Company operates in multiple taxing jurisdictions, both within the U.S. and outside the U.S. In certain situa-
tions, 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.
Net cash paid for income taxes were $18.0 million, $21.2 million and $15.3 million for the years ended

December 31, 2006, 2005 and 2004, 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 $139.2 million of foreign sub-

sidiaries’ undistributed earnings as of December 31, 2006 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 $139.2 million of foreign earnings were to be repatriated, incremental taxes may be
incurred. We do not believe this amount would be greater than $12.2 million.

Net foreign currency exchange (losses) gains, included in non-operating deductions in the Consolidated

Statements of Income, were $(268,000), $(450,000), and $(564,000) for the years ended December 31, 2006, 2005
and 2004, respectively.

NOTE 9. RESTRUCTURING CHARGES

During the fourth quarter of 2003, the Company announced plans to restructure its operations in an effort to
reduce operating costs and to improve efficiency. The Company recorded a pre-tax restructuring charge of $3.3 million
in the fourth quarter of 2003 to reflect these actions, consisting of severance, other employee benefits, and lease termi-
nation costs. During 2004, additional costs related to this program of $1.1 million were recorded. As of December 31,
2006, all employees identified in the workforce reduction were terminated and no liability remains to be paid.

NOTE 10. ACQUISITIONS

In October 2006, the Company acquired all of the outstanding stock of ASMAS, an Istanbul-based Turkish pro-
ducer of refractories for approximately $32.4 million in cash. The terms of the acquisition provides for an additional
purchase price of up to $5 million to be paid in 2009 based upon performance criteria through 2008. The opera-
tions of this entity have been included in the Refractories segment of the Company’s financial statements since the
date of the acquisition. This acquisition will allow the Company to service the growing steel industries in Eastern
Europe and the Middle East, and to provide vertical integration through its own kilns and sources of magnesite.

The purchase price allocation has not been finalized as of December 31, 2006.
The weighted average amortization period for the acquired intangible assets subject to amortization is approxi-

mately 13.5 years. Goodwill associated with this transaction is not tax deductible.

Pro forma financial information has not been presented since this business combination was not material to the

Company’s total assets or results of operations.

In the fourth quarter of 2005, the Company made a cash acquisition of the metallurgical measurement technolo-
gy/digital electrode control system product line of ET Electrotechnology GmbH for approximately $3.2 million. This
acquisition and related technology offers a power consumption system in electric steelmaking and ladle furnaces. The
Company recorded tax-deductible goodwill of approximately $1.3 million in connection with this acquisition.

In the fourth quarter of 2004, the Company recognized pre-tax corporate charges of $1.0 million expense related

to due diligence for a terminated acquisition effort. 

NOTE 11. GOODWILL AND OTHER INTANGIBLE ASSETS

The carrying amount of goodwill was $69.0 million and $53.6 million as of December 31, 2006 and December
31, 2005, respectively. The net change in goodwill since December 31, 2005 was primarily attributable to the acquisi-
tion of ASMAS and the effect of foreign exchange.

Acquired intangible assets included in other assets and deferred charges subject to amortization as of December

31, 2006 and December 31, 2005 were as follows:

Included in other assets and deferred charges is an additional intangible asset of approximately $7.3 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 cur-
rent 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 2006. Estimated amortization as a reduction of sales is as follows: 2007
- $1.8 million; 2008 - $1.8 million; 2009 - $1.5 million; 2010 - $1.2 million; 2011 - $0.9 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 establishes a uniform accounting model for dispo-
sition of long-lived assets. This statement also requires that long-lived assets be reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability
of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows
expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated cash flows, an impair-
ment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset.
During 2005, the Company recorded a writedown of impaired assets of $0.3 million for the closure of our satellite
facility at Cornwall, Canada in the first quarter of 2006.

NOTE 13. DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES

The Company is exposed to foreign currency exchange rate fluctuations and interest rate changes in the normal

course of its business. As part of its risk management strategy, the Company uses interest-rate related derivative
instruments to manage its exposure on its debt instruments, as well as 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 per-
form under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counter-
party 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 mini-
mizes 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 12 open foreign exchange con-
tracts as of December 31, 2006.

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 recog-
nized into cost of sales. Gains and losses and hedge ineffectiveness associated with these derivatives were not significant.

Thousands of Dollars

Short-term Investments

Available for Sale Securities:
Short-term bank deposits

2006

2005

$8,380

$2,350

There were no unrealized holding gains and losses on the short-term bank deposits held at December 31, 2006

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 specula-
tion. Such foreign exchange contracts would offset losses and gains on the assets, liabilities and transactions being
hedged. At December 31, 2006, the Company had open foreign exchange contracts with a financial institution to
purchase approximately $4.7 million of foreign currencies. These contracts range in maturity from February 9, 2007
to July 10, 2007. The fair value of these instruments was a liability of $0.1 million at December 31, 2006. The fair
value of the open foreign exchange contracts at December 31, 2005 was a liability of $0.2 million.

Credit risk: Substantially all of the Company’s accounts receivable are due from companies in the paper, construc-
tion 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, 2006, 2005 and 2004 was $0.4

million, $(0.5) million and $1.6 million, respectively.

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.

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 on an accelerated basis over the average remaining service period of

each active employee.

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 cur-
tailment 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 and $0.6 million in 2005 and
2004, respectively.

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 gov-
ernmental 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 1994 to 2004), 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.

For measurement purposes, health care cost trend rates of approximately 10% for pre-age-65 and post-age-65
benefits were used in 2006. These trend rates were assumed to decrease gradually to 5.0% for 2011 and remain at that
level thereafter. However, the Company will only absorb a 5% increase.

A one percentage-point change in assumed health care cost trend rates would have the following effects:

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 contri-
butions. The Company’s contributions amounted to $3.3 million, $3.0 million and $3.1 million for the years ended
December 31, 2006, 2005 and 2004, respectively.

NOTES 18. LEASES

The Company has several non-cancelable operating leases, primarily for office space and equipment. Rent
expense amounted to approximately $6.1 million, $4.6 million and $4.1 million for the years ended December 31,
2006, 2005 and 2004, respectively. Total future minimum rental commitments under all non-cancelable leases for
each of the years 2007 through 2011 and in aggregate thereafter are approximately $4.6 million, $3.6 million, $3.1
million, $2.3 million, $1.0 million, respectively, and $7.8 million thereafter. Total future minimum rentals to be
received under non-cancelable subleases were approximately $7.0 million at December 31, 2006.

Total future minimum payments to be received under direct financing leases for each of the years 2007 through

2011 and the aggregate thereafter are approximately: $4.9 million, $3.7 million, $2.7 million, $1.9 million, $1.3
million, and $2.3 million thereafter.

NOTE 19. LITIGATION

On November 28, 2005, the Company announced that it had reached a settlement of pending commercial and

patent litigation with Omya AG. The settlement was on a worldwide basis, hence the litigation in both the United
States and Italy have been dismissed. The settlement provides for the recognition of the Company’s intellectual prop-
erty and patent rights. As part of the settlement, the Company received a settlement payment and granted Omya AG a
non-exclusive license for the terms of the patents in exchange for royalty payments through 2009.

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 776 pending silica cases and 26
pending asbestos cases. In 2006, the Company was named in two new silica cases and in three new asbestos cases. To
date, 655 silica cases have been dismissed, of which 211 were dismissed in 2006. 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 2006 for the legal defense of these cases was $0.1 million.
The Company expenses legal costs when incurred. 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 char-
acterizing 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 encapsula-
tion 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 comple-
tion 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 investiga-
tions 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. 

53

Notes to Consolidated Financial Statements
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

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 is committed to
identifying appropriate improvements to the wastewater treatment system by July 1, 2007, and 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 remedia-
tion costs would approximate $350,000, which has been accrued as of December 31, 2006. It is reasonably possible
that a change in estimate may occur.

The Company and its subsidiaries are not party to any other material pending legal proceedings, other than rou-

tine 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 19,085,528 shares and 19,986,801 shares were outstanding at December 31, 2006 and
2005, respectively, and 1,000,000 shares of preferred stock, none of which were issued and outstanding.

Cash Dividends Cash dividends of $3.9 million or $0.20 per common share were paid during 2006. In January 2007,

a cash dividend of approximately $0.9 million or $0.05 per share, was declared, payable in the first quarter of 2007.
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 distrib-
uted, 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 enti-
tle the holder to vote on a pro rata basis with the Company’s common stock.

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.

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 record-
ed 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.

long-term portion of the liability of approximately $11.5 million is included in other noncurrent liabilities.

Accretion expense is included in cost of goods sold in the Company’s Consolidated Statements of Income.

NOTE 23. ACCOUNTING FOR STRIPPING COSTS

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

The following is a reconciliation of opening retained earnings:

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 25. 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 remedia-
tion, 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 26. 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 prod-
ucts limestone and talc. This segment’s products are used principally in the paper, building materials, paints and
coatings, glass, ceramic, polymers, food, and pharmaceutical industries. The Refractories segment produces and mar-
kets 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, 2006, 2005 and 2004 was as follows (in millions):

Report of Independent Registered Public Accounting Firm
Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

The Board of Directors and Shareholders
Minerals Technologies Inc.:

We have audited the accompanying consolidated balance sheets of Minerals Technologies Inc. and subsidiary com-

panies as of December 31, 2006 and 2005, and the related consolidated statements of income, shareholders’ equity,
and cash flows for each of the years in the three-year period ended December 31, 2006. In connection with our audits
of the consolidated financial statements, we also have audited the related financial statement schedule. These consoli-
dated 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, evi-
dence 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, 2006 and 2005, and
the results of their operations and their cash flows for each of the years in the three-year period ended December 31,
2006, 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, 2006, the Company adopt-

ed Statement of Financial Accounting Standards (“SFAS”) No. 123R, “Shared-Based Payment,” SFAS No. 151,
“Inventory Costs - an Amendment of ARB No. 43, Chapter 4,” and Emerging Issues Task Force Issue No. 04-06,
“Accounting for Stripping Costs Incurred During Production in the Mining Industry.” 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), the effectiveness of Minerals Technologies Inc. and subsidiary companies’ internal control over
financial reporting as of December 31, 2006, 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, 2007 expressed an unqualified opinion on management’s assessment of, and the effective
operation of, internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

on Internal Control Over Financial Reporting

Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report

The Board of Directors and Shareholders
Minerals Technologies Inc.:

We have audited management’s assessment, included in the accompanying Management’s Report on Internal Control Over Financial
Reporting, that Minerals Technologies Inc. and subsidiary companies maintained effective internal control over financial reporting as of
December 31, 2006, 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. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of 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,
evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and 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 U.S. generally accepted account-
ing principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the main-
tenance 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
U.S. 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 detec-
tion 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, projec-
tions 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.

As indicated in the accompanying Management’s Report on Internal Control Over Financial Reporting, management’s assessment of

and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of a refractories
company in Turkey acquired on October 2, 2006. This refractories company, excluding goodwill, constituted approximately 2.5% of con-
solidated total assets of the Company and less than 1% of consolidated net sales. Our audit of internal control over financial reporting of
the Company also did not include an evaluation of the internal control over financial reporting of this acquired company.

In our opinion, management’s assessment that Minerals Technologies Inc. and subsidiary companies maintained effective internal
control over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on criteria established in Internal
Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Also, in
our opinion, Minerals Technologies Inc. and subsidiary companies maintained, in all material respects, effective internal control over
financial reporting as of December 31, 2006, 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 con-
solidated balance sheets of Minerals Technologies Inc. and subsidiary companies as of December 31, 2006 and 2005, and the related con-
solidated statements of income, shareholders’ equity, and cash flows and related financial statement schedule for each of the years in the
three-year period ended December 31, 2006, and our report dated February 27, 2007 expressed an unqualified opinion on those consoli-
dated financial statements and financial statement schedule. Our report refers to the adoption in 2006 of Statement of Financial
Accounting Standards (“SFAS”) No. 123R, “Shared-Based Payment,” SFAS No. 151, “Inventory Costs - an Amendment of ARB No. 43,
Chapter 4,” Emerging Issues Task Force Issue No. 04-06, “Accounting for Stripping Costs Incurred During Production in the Mining
Industry,” and 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).”

Management’s Report 

on Internal Control Over Financial Reporting

Minerals Technologies Inc. and Subsidiary Companies 2006 Annual Report 

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 reason-
able 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 poli-
cies 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 reg-
istered 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, 2006 in relation to criteria for effective internal control over finan-
cial 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, 2006, its system of internal control over finan-
cial reporting was effective.

On October 2, 2006, the Company completed an acquisition of a refractories company in Turkey and has excluded this company from our

assessment of the effectiveness of our internal control over financial reporting. During 2006, this company contributed less than 1% of con-
solidated net sales and, as of December 31, 2006, accounted for approximately 2.5% of our consolidated total assets, excluding goodwill.

The consolidated financial statements have been audited by the independent registered public accounting firm, KPMG LLP, 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 management’s assessment of internal controls, are also presented within this document.

Our Company

Minerals Technologies  Inc.  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
related  systems  and  services.  The  Company  has  two  reportable  segments:  Specialty  Minerals  and
Refractories. The Specialty Minerals segment produces and sells the synthetic mineral product precipitat-
ed calcium carbonate (PCC) and the processed mineral product quicklime (lime), and mines, processes
and sells other 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 and phar-
maceutical industries. The Refractories segment produces and markets monolithic and shaped refractory
materials and specialty products, services and application equipment used primarily by the steel, non-fer-
rous metal and glass industries.

The  Company  emphasizes  research  and  development.  The  level  of  the  Company’s  research  and
development spending, as well as its capability of 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.

For the years of service, MTI would like to thank:
Paul R. Saueracker, Jean-Paul Vallès and John B. Curcio 

Paul R. Saueracker Paul R. Saueracker, who served as Chairman,
President, and Chief Executive Officer of Minerals Technologies Inc. since 2001,
will retire from the company on May 1, 2007. 

“Paul Saueracker has made numerous contributions to MTI over his 36
years of service, including being one of the ‘fathers of PCC’ during the 1980s, a
new technology that helped revolutionize the way paper was made in North
America,” said Joseph C. Muscari, who succeeded Mr. Saueracker. “I would like
to take this opportunity to thank Paul on behalf of all of our employees for his
dedication, perseverance and leadership.”

Mr. Saueracker joined the Company in 1971 as a Sales Representative in

Los Angeles. In 1973, he moved to New York to become a Market Research Analyst and over the years
assumed positions of increasing responsibility including Manager of Market Research and Director of Sales
and Marketing. In 1989, he became Vice President, Sales and Marketing, Minerals. He was named
President and CEO of Specialty Minerals Inc. in 1994 and a Senior Vice President of Minerals Technologies
Inc. in 1999. In August of 2000, he was elected President of the Company and a member of the Board of
Directors. In January 2001, he was elected Chief Executive Officer, and in October of 2001 he became
Chairman of the Board. 

Jean-Paul Vallès Jean-Paul Vallès, Ph.D., resigned from the MTI Board of
Directors in October of 2006. Dr. Vallès was often cited as the “father” of Minerals
Technologies Inc. after he took the company public in 1992 through an initial
public offering from Pfizer Inc, and served as Chairman and CEO from then 
until 2001, when he was named Chairman Emeritus of the Board. 

Before joining Minerals Technologies, Jean-Paul Vallès had a long and 

distinguished career at Pfizer, which he joined in 1968. While there, he assumed
positions of increasing responsibility, including Vice President of Finance and 
Chief Financial Officer, Senior Vice President, Executive Vice President and Vice
Chairman. Dr. Vallès served on the Board of Directors of Pfizer from 1980 to 2005.  

John B. Curcio John B. “Jack” Curcio, a former Chairman and Chief
Executive Officer of Mack Trucks, Inc., resigned from the Minerals Technologies
Inc. Board of Directors in May of 2006 after 14 years of service. 

Mr. Curcio was the first outside director to join the MTI Board in 1992,

when the company was formed. During his Board service, he was intimately
involved with the formulation of key strategies for growth and expansion into a
truly global company.
