Cabot Microelectronics is the world’s leading supplier of chemical mechanical planarization (CMP) slurries and a 

growing CMP pad supplier to the semiconductor industry. Our CMP consumables products are used to level, 

smooth and remove excess material from the multiple layers of material that are deposited upon silicon wafers 

in the production of most semiconductor devices. This enables our customers to manufacture smaller, faster and 

more  complex  devices.  We  also  produce  slurries  for  the  data  storage  industry  that  are  used  to  polish  certain 

600

hard disk drive components, and we are pursuing a number of other demanding surface modification applications 

through our Engineered Surface Finishes business.

We  are  delighted  to  have  achieved  record  financial 

stronger  than  ever,  which  is  reflected  in  the  number  of 

performance  in  fiscal  2010,  our  tenth  year  as  a  public

from  the  strong  recovery  of  the  global  semiconductor 

driven  our  highest  gross  profit  margin  performance  in 

industry,  I  believe  our  strong  results  also  reflect  the 

six  years.  We  believe  we  have  strengthened  our 

successful  sustained  execution  of  our  core  business 

competitive position over the past five years by refilling 

strategy.  This  strategy  is  simple  and  direct—to 

our product portfolio, improving the consistency of our

of  our  strategy  provide  clarity  for  execution  and  drive 

our  solid  operational  performance.  Over  our  ten  year 

history  as  a  public  company,  we  have  steadily  built  our 

infrastructure  and  capabilities  to  be  close  to  our 

customers.  We  now  have  approximately  half  of  our 

workforce  and  fixed  assets  located  in  the  Asia  Pacific 

region,  which  represents  the  vibrant  heart  of  the 

semiconductor industry. In conjunction, we have located 

seasoned  technical  experts  closer  to  our  customers  to 

facilitate greater collaboration and partnering within the 

highly specialized field of CMP. 

growth opportunitieS

In  particular,  I  am  energized  about  our  growing  CMP 

polishing  pad  business,  which  we  believe  currently 

represents  the  largest  organic  growth  opportunity  for 

our  company.  Over  the  past  three  years,  we  have  won 

CMP  pad  business  with  more  than  20  customers  and 

currently have many more ongoing customer evaluations. 

We  are  also  alpha  testing  our  next  generation  pad 

product platform, the Epic® D200, which we expect will 

further  broaden  our  addressable  market  and  drive 

continued  long-term  growth  in  this  important  business

Reflecting  on  the  past  ten  years,  I  have  never  felt  as 

supplier,  with  vast  knowledge  of  the  CMP  process  and 

excited  about  our  future  as  I  do  today.  Our  product 

the  demanding  expectations  of  our  semiconductor 

pipeline  is  full  of  high-quality,  value-driven  products 

customers,  we  are  well  positioned  to  be  a  strong 

and solutions. In general, our customer relationships are 

supplier of CMP pads. In addition, we believe the value 

 
 
 
 
 
 
that our pads bring to our customers through long pad 

world. We accomplished this over the last five years by 

life, lower defectivity and high degree of pad consistency 

transitioning to a direct sales model, opening a technical 

will  continue  to  drive  further  adoption  of  our  pads 

service  center  and  acquiring  Taiwan-based  Epoch 

throughout the industry. 

Within our CMP slurry business, our growth is primarily 

driven by overall wafer starts. In addition to wafer start 

growth, we have opportunities to achieve above market 

growth with our barrier and advanced dielectric slurries 

as  we  expand  our  presence  into  these  areas  where  we 

have historically been under-represented. We also plan 

to  grow  our  new  aluminum  slurry  business  as  our 

customers begin to ramp this emerging technology.

Beyond  traditional  CMP  consumables,  we  are  also 

commercializing slurries for polishing bare silicon wafers. 

We received our first customer order in this area in fiscal 

2010 and we hope to capture a meaningful portion of this 

estimated $220 million market over the next several years.

profitable growth

In  addition  to  growing  our  top  line,  we  are  also 

committed  to  expanding  our  bottom  line.  The  growth 

opportunities  that  we  are  pursuing  are  either  within  or 

very  close  to  our  core  business,  so  the  incremental 

operating costs to pursue these opportunities are low. 

For  example,  we  are  able  to  leverage  the  existing 

Material  Co.,  Ltd.,  which  had  a  significant  market, 

manufacturing and research and development presence 

in CMP slurries in Taiwan. As a result, Taiwan has grown 

from approximately 27% of our revenue in 2006 to about 

32% of our revenue in fiscal 2010. In much the same way, 

we are now looking to strengthen our business in South 

Korea,  the  second  largest  CMP  consumables  market  in 

the  world.  We  plan  to  expand  upon  our  already  solid 

sales  presence  by  establishing  manufacturing  and 

research and development capabilities there, which we 

expect will represent a capital investment of approximately 

$12  million.  By  providing  enhanced  capabilities  and 

service, we expect to grow our business with the advanced 

memory customers in South Korea.

We  also  intend  to  continue  to  pursue  potential 

acquisitions  that  we  believe  are  closely  related  to,  and 

exhibit a high degree of strategic fit with, our core CMP 

consumables business. We are focusing on opportunities 

that  would  allow  us  to  leverage  our  world-class  supply 

chain  management,  quality  systems  and  global 

infrastructure. In pursuing these potential opportunities, 

we hope to bring more electronic materials products to 

development, sales and application support teams that 

our existing customer base.

we have built for our slurry business to also service our 

CMP  pad  business.  Additionally,  in  fiscal  2010  we  were 

able  to  increase  profitability  by  improving  our  gross 

profit margin with the continued successful execution of 

our productivity initiatives, a disciplined pricing strategy 

and  increasing  pad  sales.  Further,  by  leveraging  our 

scale,  our  long-term  goal  is  to  trend  our  operating 

expenses  to  a  level  representing  approximately  30 

percent of revenue. 

next StepS

I  would  like  to  thank  our  stockholders,  customers, 

suppliers and employees for your support and continued 

confidence  in  our  company  over  the  past  ten  years. 

Overall, we believe that our competitive position is the 

strongest it has been in years, and we are excited about 

the opportunities for long-term profitable growth ahead.

Sincerely,

Much  of  our  success  today  can  be  attributed  to  the 

focus  we  have  had  on  strengthening  our  business  in 

Taiwan,  the  largest  CMP  consumables  market  in  the

Item 1. Business

Our Company
Cabot Microelectronics Corporation (“Cabot Microelec-
tronics”, “the Company”, “us”, “we”, or “our”), which 
was incorporated in the state of Delaware in 1999, is the 
leading  supplier  of  high-performance  polishing  slurries 
and a growing CMP pad supplier used in the manufac-
ture  of  advanced  integrated  circuit  (IC)  devices  within 
the  semiconductor  industry,  in  a  process  called  chemi-
cal  mechanical  planarization  (CMP).  CMP  is  a  polishing 
process used by IC device manufacturers to planarize or 
flatten  many  of  the  multiple  layers  of  material  that  are 
deposited  upon  silicon  wafers  in  the  production  of 
advanced  ICs.  Our  products  play  a  critical  role  in  the 
production  of  advanced  IC  devices,  thereby  enabling 
our customers to produce smaller, faster and more com-
plex IC devices with fewer defects.

We  currently  operate  predominantly  in  one  industry 
segment—the  development,  manufacture  and  sale  of 
CMP consumables. We develop, produce and sell CMP 
slurries  for  polishing  many  of  the  conducting  and  insu-
lating  materials  used  in  IC  devices,  and  also  for  polish-
ing  certain  components  in  hard  disk  drives,  specifically 
rigid  disk  substrates  and  magnetic  heads.  In  addition, 
we develop, manufacture and sell CMP polishing pads, 
which  are  used  in  conjunction  with  slurries  in  the  CMP 
process. We are also pursuing other demanding surface 
modification applications outside of the semiconductor 
and  hard  disk  drive  industries  for  which  we  believe  our 
capabilities  and  knowledge  may  provide  value  in 
improved surface performance or productivity.

In February 2009, we acquired Epoch Material Co., Ltd. 
(Epoch),  which  previously  was  a  consolidated  subsid-
iary  of  Eternal  Chemical  Co.,  Ltd.  (Eternal).  Epoch  is  a 
Taiwan-based  company  specializing  primarily  in  the 
development,  manufacture  and  sale  of  copper  CMP 
consumables. We believe the acquisition of Epoch pro-
vides  an  excellent  opportunity  to  strengthen  and  grow 
our  core  CMP  consumables  business,  primarily  in  the 
area of copper CMP slurries, and enhances our ability to 
innovate,  deliver  and  support  high-performing,  world-
class products to our customers around the world.

CMP Process Within IC Device Manufacturing
IC devices are components in a wide range of electronic 
systems  for  computing,  communications,  manufactur-
ing  and  transportation.  Individual  consumers  most  fre-
quently  encounter  IC  devices  as  microprocessors  in 
their desktop or laptop computers and as memory chips  

in  computers,  tablet  PCs,  cell  phones  and  digital  cam-
eras.  The  multi-step  manufacturing  process  for  IC 
devices typically begins with a circular wafer of pure sili-
con,  with  the  first  manufacturing  step  referred  to  as  a 
“wafer start.” A large number of identical IC devices, or 
dies, are manufactured on each wafer at the same time. 
The first steps in the manufacturing process build tran-
sistors  and  other  electronic  components  on  the  silicon 
wafer. These are isolated from each other using a layer 
of insulating material, most often silicon dioxide, to pre-
vent electrical signals from bridging from one transistor 
to another. These components are then wired together 
using conducting materials such as aluminum or copper 
in  a  particular  sequence  to  produce  a  functional  IC 
device with specific characteristics. When the conduct-
ing  wiring  on  one  layer  of  the  IC  device  is  completed, 
another layer of insulating material is added. The proc-
ess  of  alternating  insulating  and  conducting  layers  is 
repeated until the desired wiring within the IC device is 
achieved. At the end of the process, the wafer is cut into 
the  individual  dies,  which  are  then  packaged  to  form 
individual chips.

Demand for CMP consumable products for IC devices is 
primarily based on the number of wafer starts by semi-
conductor  manufacturers  and  the  type  and  complexity 
of  the  IC  devices  they  produce.  To  enhance  the  per-
formance  of  IC  devices,  IC  device  manufacturers  have 
progressively increased the number and density of elec-
tronic  components  and  wiring  layers  in  each  IC  device. 
As a result, the number of wires and the number of dis-
crete wiring layers have increased. As the complexity of 
IC devices has increased, the demand for CMP consum-
able  products  has  also  increased.  As  semiconductor 
technology  has  advanced  and  performance  require-
ments  of  IC  devices  have  increased,  the  percentage  of 
IC devices that utilize CMP in the manufacturing process 
has increased steadily over time. We believe that CMP is 
used  in  the  majority  of  all  IC  devices  made  today,  and 
we expect that the use of CMP will continue to increase 
in the future.

In  the  CMP  polishing  process,  CMP  consumables  are 
used to remove excess material that is deposited during 
the IC manufacturing process, and to level and smooth 
the  surfaces  of  the  layers  of  IC  devices,  via  a  combina-
tion  of  chemical  reactions  and  mechanical  abrasion, 
leaving  minimal  residue  or  defects  on  the  surface,  and 
leaving  only  the  material  necessary  for  circuit  integrity. 
CMP slurries are liquid solutions generally composed of 
high-purity  deionized  water  and  a  proprietary  mix  of 
chemical additives and engineered abrasives that chem-
ically  and  mechanically  interact  at  an  atomic  level  with 
the  surface  material  of  the  IC  device.  CMP  pads  are 
engineered  polymeric  materials  designed  to  distribute  

2

and transport the slurry to the surface of the wafer and 
distribute  it  evenly  across  the  wafer.  Grooves  are  cut 
into  the  surface  of  the  pad  to  facilitate  distribution  of 
the slurry. During the CMP process the wafer is typically 
held on a rotating carrier, which is pressed down against 
a rotating polishing table and spun in a circular motion. 
The portion of the table that comes in contact with the 
wafer is covered by a polishing pad. A CMP slurry is con-
tinuously  applied  to  the  polishing  pad  to  facilitate  and 
enhance  the  polishing  process.  Hard  disk  drive  manu-
facturers use similar processes to smooth the surface of 
substrate disks before depositing magnetic media onto 
the disk.

An effective CMP process is achieved through technical 
optimization  of  the  CMP  consumables  in  conjunction 
with  an  appropriately  designed  CMP  process.  Prior  to 
introducing  new  or  different  CMP  slurries  or  pads  into 
its  manufacturing  process,  an  IC  device  manufacturer 
generally  requires  the  product  to  be  qualified  in  its 
proc esses through an extensive series of tests and eval-
uations. These qualifications are intended to ensure that 
the  CMP  consumable  product  will  function  properly 
within  the  customers’  overall  manufacturing  processes. 
These tests and evaluations may require minor changes 
to the CMP process or the CMP slurry or pad. While this 
qualification  process  varies  depending  on  numerous 
factors,  it  is  generally  quite  costly  and  may  take  six 
months or longer to complete. IC device manufacturers 
usually  take  into  account  the  cost,  time  required  and 
impact  on  production  when  they  consider  implement-
ing or switching to a new CMP slurry or pad.

CMP  enables  IC  device  manufacturers  to  produce 
smaller,  faster  and  more  complex  IC  devices  with  a 
greater density of transistors and other electronic com-
ponents  than  is  possible  without  CMP.  By  enabling  IC 
device manufacturers to make smaller IC devices, CMP 
also  allows  them  to  increase  the  number  of  IC  devices 
that  fit  on  a  wafer.  This  increase  in  the  number  of  IC 
devices  per  wafer  in  turn  increases  the  throughput,  or 
the number of IC devices that can be manufactured in a 
given  time  period,  and  thereby  reduces  the  cost  per 
device. CMP also helps reduce the number of defective 
or  substandard  IC  devices  produced,  which  increases 
the device yield. Improvements in throughput and yield 
reduce  an  IC  device  manufacturer’s  unit  production 
costs, and reducing costs is one of the highest priorities 
of  a  semiconductor  manufacturer  as  the  return  on  its 
significant investment in manufacturing capacity can be 
enhanced  by  lower  unit  costs.  More  broadly,  sustained 
growth  in  the  semiconductor  industry  traditionally  has 
been  fueled  by  enhanced  performance  and  lower  unit 
costs, making IC devices more affordable in an expand-
ing range of applications.

Precision Polishing
Through  our  Engineered  Surface  Finishes  (ESF)  busi-
ness,  we  are  applying  our  technical  expertise  in  CMP 
consumables  and  polishing  techniques  developed  for 
the  semiconductor  industry  to  demanding  applications 
in other industries where shaping, enabling and enhanc-
ing the performance of surfaces is critical to success.

Many of the production processes currently used in pre-
cision machining and polishing have been based on tra-
ditional,  labor-intensive  techniques,  which  are  being 
replaced  by  computer-controlled,  deterministic  proc-
esses. Our wholly-owned subsidiary, QED Technologies 
International, Inc. (QED), is a leading provider of deter-
ministic  finishing  technology  for  the  precision  optics 
industry.  We  believe  precision  optics  are  pervasive, 
serving several existing large markets such as semicon-
ductor  equipment,  aerospace,  defense,  security  and 
telecommunications.

Our Products

CMP Consumables for IC Devices
We  develop,  produce  and  sell  CMP  slurries  for  a  wide 
range  of  polishing  applications  of  materials  that  con-
duct  electrical  signals,  including  tungsten,  copper,  alu-
minum and tantalum (commonly referred to as “copper 
barrier” or “barrier”). Slurries for polishing tungsten are 
used heavily in the production of memory devices for a 
multitude  of  end  applications  such  as  computers,  MP3 
players,  cellphones,  gaming  devices,  digital  photogra-
phy  and  digital  video  recorders,  as  well  as  in  mature 
logic  applications  such  as  those  used  in  automobiles. 
Our  most  advanced  slurries  for  tungsten  polishing  are 
designed  to  be  customized  to  provide  customers 
greater flexibility, improved performance and a reduced 
cost  of  ownership.  Our  slurries  for  polishing  copper  
and  barrier  materials  are  used  primarily  in  the  produc-
tion of advanced IC logic devices such as microproces-
sors  for  computers,  and  devices  for  graphic  systems, 
gaming  systems  and  communication  devices.  These 
products  include  different  slurries  for  polishing  the  
copper  film  and  the  thin  barrier  layer  used  to  separate 
copper  from  the  adjacent  insulating  material.  These 
same copper and barrier slurries are now being used in 
the CMP process for memory devices as well. We offer 
multiple  products  for  each  technology  node  to  enable 
different  integration  schemes  depending  on  specific 
customer needs.

We  also  develop,  manufacture  and  sell  slurry  products 
used  to  polish  the  dielectric  insulating  materials  that 
separate conductive layers within logic and memory IC 
devices.  Our  core  slurry  products  for  these  materials  
are  primarily  used  for  high  volume  applications  called

Interlayer Dielectric or ILD. Our advanced dielectrics 
products are designed to meet the more stringent and 
complex  performance  requirements  of  lower-volume, 
more  specialized  dielectric  polishing  applications  at 
advanced technology nodes.

We  develop,  produce  and  sell  CMP  polishing  pads, 
which  are  consumable  materials  that  work  in  conjunc-
tion  with  CMP  slurries  in  the  CMP  polishing  process.  
We believe that CMP polishing pads represent a natural 
adjacency  to  our  CMP  slurry  business,  since  the  tech-
nologies are closely related and utilize the same techni-
cal and sales infrastructure. We believe our unique pad 
material and our continuous pad manufacturing process 
enable  us  to  produce  a  pad  with  a  longer  pad  life, 
greater  consistency  from  pad  to  pad,  and  enhanced 
performance,  resulting  in  lower  cost  of  ownership  for 
our customers. We are producing and selling pads that 
can be used on a variety of polishing tools, over a range 
of  applications  including  tungsten,  copper  and  dielec-
trics,  over  a  range  of  technology  nodes,  and  on  both 
200mm and 300mm wafers.

CMP Consumables for the Data Storage Industry
We develop and produce CMP slurries for polishing the 
materials that coat rigid disks and magnetic heads used 
in hard disk drives for computer and other data storage 
applications,  which  represent  an  extension  of  our  core 
CMP  slurry  technology  and  manufacturing  capabilities 
established for the semiconductor industry. We believe 
CMP  significantly  improves  the  surface  finish  of  these 
coatings,  resulting  in  greater  storage  capacity  of  the 
hard disk drive systems, and also improves the produc-
tion  efficiency  of  manufacturers  of  hard  disk  drives  by 
helping increase their throughput and yield.

Precision Optics Products
Through  our  QED  subsidiary,  we  design  and  produce 
precision polishing and metrology systems for advanced 
optic  applications  that  allow  customers  to  attain  near-
perfect  shape  and  surface  finish  on  a  range  of  optical 
components such as mirrors, lenses and prisms. Histori-
cally, advanced optics have been produced using labor-
intensive  artisan  processes,  and  variability  has  been 
common. QED has automated the polishing process for 
advanced  optics  to  enable  rapid,  deterministic  and 
repeatable  surface  correction  to  the  most  demanding 
levels of precision in dramatically less time than with tra-
ditional means. QED’s polishing systems use Magneto-
Rheological  Finishing  (MRF),  a  proprietary  surface 
figuring  and  finishing  technology,  which  employs  mag-
netic  fluids  and  sophisticated  computer  technology  to 
polish  a  variety  of  shapes  and  materials.  Its  metrology  

systems  use  Subaperture  Stitching  Interferometry  (SSI) 
technology  that  captures  precise  metrology  data  for 
large  and/or  strongly  curved  optical  parts  and  an 
Aspheric  Stitching  Inter ferometer  (ASI),  which  is 
designed  to  measure  increasingly  complex  shapes, 
including non-spherical surfaces, or aspheres.

Strategy
We  collaborate  closely  with  our  customers  to  design 
and  manufacture  products  that  offer  innovative  and  
reliable  solutions  to  our  customers’  challenges  and  we 
strive  to  consistently  and  reliably  deliver  and  support 
these  products  around  the  world.  We  continue  to  
focus  on  the  execution  of  our  primary  strategy  of 
strengthening and growing our core CMP consumables 
business  within  the  semiconductor  and  hard  disk  drive 
industries. We are also leveraging our expertise in CMP 
process and slurry formulation to expand our ESF busi-
ness in the optics and electronic substrates markets.

Strengthen and Grow Our Core CMP  
Consumables Business
As  the  leader  in  the  CMP  slurry  industry,  we  intend  to 
grow our core CMP consumables business through the 
execution of our three strategic initiatives—maintaining 
our  technological  leadership,  striving  for  operations 
excellence  and  connecting  with  our  customers.  We 
believe  our  strong  financial  position  allows  us  to  fund 
growth  opportunities  in  our  core  CMP  consumables 
business  through  internally  developed  technologies  as 
well  as  through  potential  acquisitions  of  technologies 
and  businesses  such  as  our  acquisition  of  Epoch  in  
fiscal 2009.

Technology Leadership: We believe that technology and 
innovation are vital to success in our CMP consumables 
business and we devote significant resources to research 
and development. We continue to develop and produce 
new  CMP  products  to  address  existing  and  new  CMP 
applications  and  we  have  built  a  strong,  worldwide  
intellectual property portfolio to protect our investment 
in  these  new  products.  We  believe  our  new  product 
pipeline contains a number of high-value products that 
will  provide  our  customers  with  enabling  solutions 
across a number of CMP application areas at advanced 
technology nodes. We need to stay ahead of the rapid 
technological  advances  in  the  electronics  industry  in 
order to deliver a broad line of CMP consumables prod-
ucts that meet or exceed our customers’ evolving needs. 
We  have  established  research  and  development  facili-
ties  in  the  United  States,  Japan,  Taiwan  and  Singapore 
in order to meet our customers’ technology needs on a 
global basis.

Operations  Excellence:  We  believe  that  product  and 
supply chain quality is critical to success in our business. 
Our  customers  demand  increasing  performance  of  our 
products  in  terms  of  product  quality  and  consistency. 
We  strive  to  drive  out  variation  in  our  products  and 
proc esses in order to increase quality, productivity and 
efficiency,  and  improve  the  uniformity  and  consistency 
of performance of our CMP consumable products. Our 
global  manufacturing  sites  are  managed  to  ensure  we 
have  the  people,  training  and  systems  needed  to  sup-
port  the  unique  industry  demands  for  product  quality. 
To support our operations excellence initiative, we have 
adopted the concepts of Six Sigma across our Company. 
Six  Sigma  is  a  systematic,  data-driven  approach  and 
methodology for improving quality by reducing variabil-
ity. We believe our Six Sigma initiatives have contributed 
to significant, sustained improvement in productivity in 
our  operations  over  the  past  six  fiscal  years,  which  we 
believe  contributed  to  the  improvement  in  our  gross 
profit margin in fiscal 2010. We also have extended our 
Six Sigma initiative to include joint projects with custom-
ers and vendors. We continue to make improvements to 
our supply chain to improve the quality and consistency 
of our products, processes and raw materials, as well as 
to expand our production capacity.

Connecting With Our Customers: We believe that build-
ing  close  relationships  with  our  customers  is  a  key  to 
achieving long-term success in our business. We collab-
orate  with  our  customers  on  joint  projects  to  identify 
and develop new and better CMP consumables, to inte-
grate  our  products  into  their  manufacturing  processes, 
and to assist them with supply, warehousing and inven-
tory  management.  Our  customers  demand  a  highly  
reliable  supply  source,  and  we  believe  we  have  a  com-
petitive  advantage  because  of  our  ability  to  timely 
deliver high-quality products and service from the early 
stages  of  product  development  through  the  high- 
volume  commercial  use  of  our  products.  We  strategi-
cally  locate  our  research  facilities  and  clean  rooms, 
manufacturing operations and the related technical and 
customer  support  teams  to  be  responsive  to  our  cus-
tomers’  needs.  We  believe  our  extensive  research  and 
development facilities in close proximity to our custom-
ers provides a competitive advantage as our customers 
are able to test our CMP products on their wafers in our 
facilities during periods of strong semiconductor indus-
try  demand,  rather  than  diverting  their  production 
resources  from  producing  IC  devices  to  testing  CMP 
products.  In  addition,  we  recently  announced  we  have 
entered  into  a  non-binding  memorandum  of  under-
standing with the Gyeonggi Province of South Korea to 
potentially  establish  manufacturing  and  research  and 
development  capabilities  there,  in  close  proximity  to 
some of the largest manufacturers of memory devices in 
the world.

The following are some examples of the successful exe-
cution of our strategic initiatives during fiscal 2010.

•   Through  our  Six  Sigma  initiatives  and  through  other 
mechanisms, we have driven sustained improvements 
in our supply chain operations.
   In fiscal 2010, we improved manufacturing yields for 
our CMP slurry products. The improvement in yields 
combined  with  an  increase  in  the  utilization  of  our 
manufacturing capacity helped us achieve our high-
est gross profit margin since fiscal 2003.
   We achieved a record level of productivity improve-
ment in fiscal 2010 and have reduced product varia-
tion by more than 90 percent over the past six years.
   We successfully achieved a sustained period of high 
production levels, following a period of great volatil-
ity in fiscal 2009.

•   We  continued  to  grow  our  pad  business,  increasing 
pad  revenue  nearly  70%,  from  $17.7  million  in  fiscal 
2009 to $29.9 million in fiscal 2010.
   We successfully transitioned a portion of our manu-
facturing  activity  to  the  on-site  production  facility 
within one of Taiwan Semiconductor Manufacturing 
Company’s  (TSMC)  fabs.  This  has  enabled  us  to 
reduce  logistics  and  packaging  costs  as  well  as 
improve our turnaround time to fill TSMC orders.
   We continued to make progress in the development 
of new pad products. We are alpha testing our next 
generation  pad  platform,  the  D200,  with  a  small 
number of customers and we have a number of cus-
tomers  evaluating  product  extensions  within  our 
existing D100 product portfolio.

•   We continued to capture customer feedback through 
a  variety  of  avenues,  including  customer-supplied 
scorecards  and  Company-initiated  surveys.  We  use 
the  feedback  from  our  customers  to  drive  further 
improvements  in  our  business  to  increase  customer 
satisfaction.
   Our  customer  satisfaction  performance,  based  on 
customer-supplied scorecards and our own surveys, 
has continued to improve year after year.
   We  continued  to  receive  customer  awards  recog-
nizing the Company as a key supplier, including sup-
plier  awards  from  a  number  of  key  customers 
including  TSMC,  Intel,  United  Microelectronics 
Corporation (UMC) and Samsung.

Leverage Our Expertise into New Markets—
Engineered Surface Finishes Business
In addition to strengthening and growing our core CMP 
business,  we  continue  to  pursue  development  of  our 
ESF business. We believe we can leverage our expertise 
in CMP consumables for the semiconductor industry to 
develop products for demanding polishing applications 
in other industries that are synergistic to our CMP con-
sumables business. We are focusing on opportunities in 
precision optics and electronic substrates.

Similar  to  our  core  CMP  business,  our  ESF  business  is 
technology  driven.  For  example,  we  believe  our  QED 
subsidiary is the technology leader in deterministic fin-
ishing  for  the  precision  optics  industry.  In  fiscal  2010, 
QED  commercialized  its  new  ASI  technology,  which 
enables customers to measure complex optical shapes, 
including steeply non-spherical surfaces.

Industry Trends

Semiconductor Industry
We  believe  the  semiconductor  industry  continues  to 
demonstrate  several  clear  trends:  the  semiconductor 
business demonstrates cyclical growth; there is constant 
pressure  to  reduce  costs;  and  the  customer  base  is 
consolidating.

The  cyclical  nature  of  the  semiconductor  industry  is 
closely tied to the global economy as well as to supply 
and  demand  within  the  industry.  The  semiconductor 
industry  experienced  significant  growth  during  our  fis-
cal  2010,  following  its  contraction  in  fiscal  2009  due  to 
the severe global recession. This strong industry recov-
ery positively affected the demand for our products. We 
began  to  see  signs  of  recovery  in  the  semiconductor 
industry  during  the  second  half  of  fiscal  2009  as  semi-
conductor manufacturers began to replenish inventories 
in response to improvement in the underlying demand. 
In response to this increase in underlying demand, semi-
conductor  manufacturers  have  increased  their  produc-
tion of IC devices to levels which may require additions 
to  their  production  capacity,  which  could  positively 
affect the future demand for our products. Although the 
timing  and  pace  of  a  broad  global  economic  recovery 
remains uncertain, we believe that semiconductor indus-
try  demand  will  grow  over  the  long  term  based  on 
increased usage of IC devices and an expanding range 
of  uses  of  these  devices.  We  also  believe  that  our 
Company is well positioned to operate successfully over 
a  range  of  demand  environments  as  we  have  success-
fully navigated our business through a number of indus-
try cycles in the past.

As the demand for more advanced and lower cost elec-
tronic devices grows, there is continued pressure on IC 
device manufacturers to reduce their costs. Many manu-
facturers reduce costs by pursuing ever-increasing scale 
in their operations. In addition, manufacturers seek ways 
to  increase  their  production  yield  while  reducing  their 
production costs regardless of the number of units they 
produce. They look for CMP consumables products with 
improved  quality  and  performance  that  reduce  their 
overall  cost  of  ownership,  they pursue  ways  to  use  less 
CMP materials, and they also aggressively pursue price 
reductions  on  the  materials  they  buy.  This  pressure  on 
manufacturers to reduce costs has also led a number of  

integrated device manufacturers to continually increase 
the use of foundries where they can outsource some or 
all  of  their  manufacturing  to  reduce  their  fixed  costs. 
This  approach  also  leads  to  increasing  scale  and  lower 
costs for these foundries.

The number of semiconductor manufacturers continues 
to  decline  both  through  mergers  and  acquisitions  as 
well  as  through  alliances  among  different  companies. 
Smaller manufacturers do not appear to have the tech-
nology  or  resources  necessary  to  compete  with  the 
large  manufacturers  on  the  global  basis  needed  in 
today’s market. Many of our customers are forming con-
sortia and research and development alliances to better 
manage the high cost of their development activities.

CMP Consumables Industry
Demand  for  CMP  consumables  is  primarily  driven  by 
wafer starts, so the CMP consumables industry reflects 
the  cyclicality  of  the  semiconductor  industry  as  well  as 
changes  in  global  economic  conditions.  Our  financial 
results  for  fiscal  years  2010  and  2009  clearly  demon-
strated these effects. We saw the benefits of increased 
production levels in the semiconductor industry in fiscal 
2010  as  our  revenues  in  fiscal  2010  increased  over  40% 
from  fiscal  2009.  This  was  in  stark  contrast  to  the  first 
half of our fiscal 2009 when we saw the adverse effects 
of the global economic recession that caused our reve-
nues  for  the  first  six  months  of  fiscal  2009  to  decrease 
over  42%  from  the  comparable  period  of  fiscal  2008. 
Over the long term, we anticipate the worldwide market 
for CMP consumables used by IC device manufacturers 
will  grow  as  a  result  of  expected  long-term  growth  in 
wafer starts, growth in the percentage of IC devices pro-
duced  that  require  CMP,  an  increase  in  the  number  of 
CMP polishing steps required to produce these devices 
and  the  introduction  of  new  materials  in  the  manufac-
ture of semiconductor devices.

We  expect  the  anticipated  growth  in  demand  will  be 
somewhat  mitigated  by  increased  efficiencies  in  CMP 
consumable  usage  as  customers  seek  to  reduce  their 
costs.  Semiconductor  manufacturers  look  for  ways  to 
lower the cost of CMP consumables in their production 
operations,  including  diluting  slurry  or  reducing  the 
slurry  flow  rate  during  production  to  reduce  the  total 
amount of slurry used, and extending the polishing time 
before replacing pads.

As semiconductor technology continues to advance, we 
believe that CMP technical solutions are becoming more 
complex,  and  leading-edge  technologies  generally 
require  some  customization  by  customer,  tool  set  and 
process  integration  approach.  Leading-edge  device 
designs  are  introducing  more  materials  and  processes 
into next generation chips, and these new materials and  

6

processes must be considered in developing CMP solu-
tions.  As  a  result,  customers  are  selecting  suppliers  
earlier in their development processes and are maintain-
ing preferred supplier relationships through production. 
We believe that close collaboration between customers 
and  suppliers  offers  the  best  opportunity  for  optimal 
CMP solutions. We also believe that research and devel-
opment  programs  are  important  as  we  develop  inno-
vative,  high-performing  and  more  cost-effective  CMP 
solutions.

Competition
We compete in the CMP consumables industry, which is 
characterized  by  rapid  advances  in  technology  and 
demanding  product  quality  and  consistency  require-
ments.  We  face  competition  from  other  CMP  consum-
ables  suppliers,  and  we  also  may  face  competition  in  
the  future  from  significant  changes  in  technology  or 
emerging  technologies.  However,  we  believe  we  are 
well  positioned  to  continue  our  leadership  in  the  CMP 
slurry  industry,  and  to  continue  to  grow  our  CMP  pad 
business.  We  believe  we  have  the  experience,  scale, 
capabilities and infrastructure that are required for suc-
cess,  and  we  work  closely  with  the  largest  customers  
in  the  semiconductor  industry  to  meet  their  growing 
expectations.

Our  CMP  slurry  competitors  range  from  small  compa-
nies that compete with a single product and/or in a sin-
gle geographic region to divisions of global companies 
with multiple lines of  CMP products  for  IC  manufactur-
ers. However, we believe we have more CMP slurry busi-
ness than any other provider. In our view, we are the only 
CMP  slurry  supplier  today  that  serves  a  broad  range  
of  customers  by  offering  and  supporting  a  full  line  of  
CMP  slurry  products  for  all  major  applications  over  a 
range  of  technologies,  and  that  has  a  proven  track 
record of supplying these products globally in high vol-
umes with the attendant required high level of technical 
support services.

With respect to CMP polishing pads, a single entity has 
held  the  dominant  market  position  for  a  number  of 
years. A number of other companies are attempting to 
enter  this  market,  providing  potentially  viable  product 
alternatives. We believe our pad materials and our con-
tinuous pad manufacturing process have enabled us to 
produce  a  pad  with  a  longer  pad  life,  lower  defectivity 
and  greater  consistency  for  our  customers,  thus  reduc-
ing their total pad cost. We believe this has fueled sig-
nificant growth in sales of our pad products and we are 
currently alpha testing with our customers our next gen-
eration  of  pad  products  which  we  believe  could  offer 
our  customers  an  even  better  solution  over  a  broad 
range  of  applications.  We  believe  we  are  now  the  sec-
ond largest seller of polishing pads in the world.

Our  QED  subsidiary  operates  in  the  precision  optics 
industry.  There  are  few  direct  competitors  of  QED 
because its technology is relatively new and unique. We 
believe QED’s technology provides a competitive advan-
tage to customers in the precision optics industry which 
still  relies  heavily  on  traditional  artisan-based  methods 
of fabrication.

Customers, Sales and Marketing
Within  the  semiconductor  industry,  our  customers  are 
primarily  producers  of  logic  IC  devices,  producers  of 
memory  IC  devices  and  IC  foundries.  Often,  logic  and 
memory  companies  outsource  some  or  all  of  the  pro-
duction  of  their  devices  to  foundries,  which  provide  
contract  manufacturing  services,  in  order  to  avoid  the 
high  cost  of  process  development,  constructing  and 
operating a fab, or in cases where they need additional 
capacity.

Based upon our own observations and customer survey 
results,  we  believe  the  following  factors  influence  our 
customers’  CMP  buying  decisions:  overall  cost  of  own-
ership,  which  represents  the  cost  to  purchase,  use  and 
maintain  a  product;  product  quality  and  consistency; 
product  yield  and  performance;  engineering  support; 
and  delivery/supply  assurance.  We  believe  that  greater 
customer  sophistication  in  the  CMP  process,  more 
demanding integration schemes, additional and unique 
polishing  materials  and  cost  pressures  will  add  further 
demands  on  CMP  consumable  suppliers.  When  these 
factors  are  combined  with  our  customers’  desires  to 
gain purchasing leverage and lower their cost of owner-
ship,  we  believe  that  only  the  most  reliable,  innovative, 
cost effective, service driven CMP consumables suppli-
ers will thrive.

We use an interactive approach to build close relation-
ships  with  our  customers  in  a  variety  of  areas  and  we 
have  customer-focused  teams  located  in  each  major 
geographic  region  of  sales.  Our  sales  process  begins 
long before the actual sale of our products and occurs 
on a number of levels. Due to the long lead times from 
research  and  development  to  product  commercializa-
tion and sales, we have research teams that collaborate 
with  customers  on  emerging  applications  years  before 
the products are required by the market. We also have 
development teams that coordinate with our customers, 
using our research and development facilities and capa-
bilities to design CMP products tailored to their precise 
needs. Next, our applications engineers work with cus-
tomers to integrate our products into their manufactur-
ing  processes.  Finally,  as  part  of  our  sales  process,  our 
logistics and sales personnel provide supply, warehous-
ing and inventory management for our customers.

We  market  our  products  primarily  through  direct  sales 
to our customers, although we use distributors in select 
areas.  We  believe  this  strategy  is  one  way  we  can  
achieve  our  goal  of  connecting  more  closely  with  our 
customers.

Our QED subsidiary supports customers in the semicon-
ductor  equipment,  aerospace,  defense,  security  and 
telecommunications  markets.  QED  counts  among  its 
worldwide  customers  leading  precision  optics  manu-
facturers,  major  semiconductor  original  equipment 
manufacturers,  the  United  States  government  and  its 
contractors.

In  fiscal  2010,  our  five  largest  customers  accounted  for 
approximately 48% of our revenue, with TSMC and UMC 
accounting for approximately 18% and 11% of our reve-
nue,  respectively.  For  additional  information  on  con-
centration of customers, refer to Note 2 of “Notes to the 
Consolidated  Financial  Statements”  included  in  Item  8 
of Part II of this Form 10-K.

Research, Development and Technical Support
We  believe  that  technology  is  vital  to  success  in  our 
CMP business and in our ESF business, and we plan to 
continue  to  devote  significant  resources  to  research, 
development and technical support (R&D), and balance 
our efforts between the shorter-term market needs and 
the  longer-term  investments  required  of  us  as  a  tech-
nology  leader.  We  develop  and  formulate  new  and 
enhanced  CMP  consumables  and  new  CMP  processes 
tailored  to  our  customers’  needs.  We  work  closely  
with our customers at their facilities to identify their spe-
cific  technology  and  manufacturing  challenges  and  
to  translate  these  challenges  into  viable  CMP  process 
solutions.

Our  technology  efforts  are  currently  focused  on  five 
main areas that span the early conceptual stage of prod-
uct  development  involving  new  materials,  processes 
and designs several years in advance of commercializa-
tion,  through  to  continuous  improvement  of  already 
commercialized products in daily use in our customers’ 
manufacturing facilities. These five areas are:

•   Research related to fundamental CMP technology;

•   Development  and  formulation  of  new  and  enhanced 
CMP  consumables  products,  including  collaborating 
on joint development projects with our customers;

•   Process  development  to  support  rapid  and  effective 

commercialization of new products;

•   Technical support of CMP products in our customers’ 

manufacturing facilities; and

•   Evaluation  and  development  of  new  polishing  and 
metrology applications outside of the semiconductor 
industry.

Our  research  in  CMP  slurries  and  pads  addresses  a 
breadth of complex and interrelated performance crite-
ria that relate to the functional performance of the chip, 
our  customers’  manufacturing  yields,  and  their  overall 
cost of ownership. We design slurries and pads that are 
capable of polishing one or more materials of differing 
hardness, sometimes at the same time, that make up the 
semiconductor circuitry. Additionally, our products must 
achieve the desired surface conditions at high polishing 
rates, high processing yields and low consumables costs 
in  order  to  earn  acceptable  system  economics  for  our 
customers. As dimensions become smaller and as mate-
rials  and  designs  increase  in  complexity,  these  chal-
lenges require significant investments in R&D.

We  also  commit  internal  R&D  resources  to  our  ESF  
business. We believe that application areas we are cur-
rently  developing,  such  as  precision  optics  and  elec-
tronic  substrates,  represent  natural  adjacencies  to  our 
core  CMP  business  and  technology.  Products  under 
development  include  products  used  to  polish  silicon  
and silicon-carbide wafers to improve the surface qual-
ity of these wafers and reduce the customers’ total cost 
of ownership.

We believe that a competitive advantage may be gained 
through  technology  leadership,  and  that  our  invest-
ments  in  R&D  provide  us  with  leading-edge  polishing 
and metrology capabilities to support the most advanced 
and  challenging  customer  technology  requirements  on 
a global basis. In fiscal 2010, 2009 and 2008, we incurred 
approximately $51.8 million, $48.2 million and $49.2 mil-
lion, respectively, in R&D expenses. We believe our Six 
Sigma initiatives in our R&D efforts allow us to conduct 
more research at a lower cost. Investments in property, 
plant  and  equipment  to  support  our  R&D  efforts  are 
capitalized  and  depreciated  over  their  useful  lives.  We 
operate  a  R&D  facility  in  Aurora,  Illinois,  that  is  staffed 
by a team that includes experts from the semiconductor 
industry and scientists from key disciplines required for 
the  development  of  high-performance  CMP  consum-
able products. This facility features a Class 1 clean room 
and  advanced  equipment  for  product  development, 
including  300mm  polishing  and  metrology  capabilities, 
the  experimental  results  from  which  we  believe  corre-
late  with  what  our  customers  experience  when  using  
our  products  in  their  factories.  In  addition,  we  operate  
a  technology  center  in  Japan,  which  includes  300mm  
polishing, metrology and slurry development capability, 
which  we  believe  enhances  our  ability  to  provide  opti-
mized CMP solutions to our customers in the Asia Pacific 
region. Epoch also has R&D capability, including a clean 
room with 200mm polishing capability. All of these facil-
ities underscore our commitment both to continuing to 
invest  in  our  technology  infrastructure  to  maintain  our 
technology  leadership,  and  to  becoming  even  more  

8

9

responsive to the needs of our customers. Other exam-
ples of this commitment include our QED research facil-
ity  in  Rochester,  New  York,  as  well  as  our  laboratory  in 
Singapore  that  provides  additional  slurry  formulation 
capability to support the data storage industry.

Raw Materials Supply
Metal oxides, such as silica and alumina, are significant 
raw materials we use in many of our CMP slurries. In the 
interest  of  supply  assurance,  our  strategy  is  to  secure 
multiple sources of raw materials and qualify and moni-
tor  those  sources  as  necessary  to  ensure  our  supply  of 
raw  materials  remains  uninterrupted.  Also,  we  have 
entered into multi-year supply agreements with a num-
ber of suppliers for the purchase of raw materials, includ-
ing  agreements  with  Cabot  Corporation,  which  is  not  
a  related  party,  for  the  purchase  of  certain  amounts  
and types of fumed silica and fumed alumina. For addi-
tional information regarding these agreements, refer to 
“Tabular  Disclosure  of  Contrac tual  Obligations,”  
included  in  “Management’s  Discussion  and  Analysis  
of  Financial  Condition  and  Results  of  Operations,”  in 
Item 7 of Part II of this Form 10-K.

Intellectual Property
Our  intellectual  property  is  important  to  our  success 
and ability to compete. As of October 31, 2010, we had 
201  active  U.S.  patents  and  82  pending  U.S.  patent 
applications.  In  most  cases  we  file  counterpart  foreign 
patent  applications.  Many  of  these  patents  are  impor-
tant to our continued development of new and innova-
tive products for CMP and related processes, as well as 
for  new  businesses.  Our  patents  have  a  range  of  dura-
tion  and  we  do  not  expect  to  lose  any  material  patent 
through expiration in the next five years. We attempt to 
protect  our  intellectual  property  rights  through  a  com-
bination of patent, trademark, copyright and trade 
secret laws, as well as employee and third party nondis-
closure and assignment agreements. We vigorously and 
proactively  pursue  parties  that  attempt  to  compromise 
our investments in research and development by infring-
ing our intellectual property. For example, in January 
2007, we filed a legal action against DuPont Air Products 
NanoMaterials  LLC  (DA  Nano),  a  competitor  of  ours, 
charging that DA Nano’s manufacture and marketing of 
certain CMP slurries infringe certain CMP slurry patents 
that  we  own,  as  a  counterclaim  to  DA  Nano’s  filing  an 
action  charging  that  those  patents  are  invalid.  In  July 
2010, a jury trial was completed in connection with this 
ongoing litigation where the validity of all of our patents 
at  issue  in  the  matter  was  upheld.  We  believe  this  is 
important because the testing of these patents through 
the  U.S.  judicial  process  has  increased  the  strength  of 
our  intellectual  property  and  our  ability  to  enforce  it. 
However,  we  were  disappointed  that  the  jury  did  not 
find  that  DA  Nano’s  products  at  issue  infringe  on  our 

patents. In November 2010, we filed a Notice of Appeal 
regarding  infringement,  and  DA  Nano  filed  a  cross-
appeal. With respect to the same patents, we have been 
successful  before  the  United  States  International  Trade 
Commission  in  prohibiting  the  importation  and  sale 
within  the  United  States  of  infringing  products  by 
another competitor.

Most  of  our  intellectual  property  has  been  developed 
internally, but we also may acquire intellectual property 
from  others  to  enhance  our  intellectual  property  port-
folio.  These  enhancements  may  be  via  licenses  or 
assignments or we may acquire certain proprietary tech-
nology and intellectual property when we make acquisi-
tions,  such  as  through  our  acquisitions  of  Epoch,  QED 
and  Surface  Finishes  Co.  We  believe  these  technology 
rights  continue  to  enhance  our  competitive  advantage 
by  providing  us  with  future  product  development 
opportunities  and  expanding  our  already  substantial 
intellectual property portfolio.

Environmental Matters
Our  facilities  are  subject  to  various  environmental  laws 
and  regulations,  including  those  relating  to  air  emis-
sions, wastewater discharges, the handling and disposal 
of solid and hazardous wastes, and occupational safety 
and health. We believe that our facilities are in substan-
tial compliance with applicable environmental laws and 
regulations.  By  utilizing  Six  Sigma  in  our  environmental 
management  system  process,  we  believe  we  have 
improved  operating  efficiencies  while  protecting  the 
environment.  Our  operations  in  the  United  States, 
Japan, Singapore, Wales and Taiwan are ISO 14001 cer-
tified,  which  requires  that  we  implement  and  operate 
according  to  various  procedures  that  demonstrate  our 
dedication to waste reduction, energy conservation and 
other  environmental  concerns.  We  are  committed  to 
maintaining  these  certifications  and  are  actively  pursu-
ing  ISO  18001  Safety  and  Health  certification  for  our 
existing operations over the next two years. We will also 
obtain  additional  certifications,  as  applicable,  in  the 
areas  in  which  we  do  business.  We  have  incurred,  and 
will  continue  to  incur,  capital  and  operating  expendi-
tures and other costs in complying with these laws and 
regulations  in  both  the  United  States  and  abroad. 
However, we currently do not anticipate that the future 
costs  of  environmental  compliance  will  have  a  material 
adverse  effect  on  our  business,  financial  condition  or 
results of operations.

Employees
We  believe  we  have  a  world-class  team  of  employees 
who  make  our  Company  successful.  As  of  October  31, 
2010,  we  employed  933  individuals,  including  493  in 
operations, 229 in research and development and tech-
nical,  96  in  sales  and  marketing  and  115  in  administra-
tion.  None  of  our  employees  are  covered  by  collective 

10

11

bargaining  agreements.  We  have  not  experienced  any 
work  stoppages  and  in  general  consider  our  relations 
with our employees to be good.

Financial Information About Geographic Areas
We sell our products worldwide. Our geographic coverage 
allows us to utilize our business and technical expertise 
from  a  worldwide  workforce,  provides  stability  to  our 
operations  and  revenue  streams  to  offset  geography-
specific  economic  trends,  and  offers  us  an  opportunity 
to take advantage of new markets for products.

For more financial information about geographic areas,

Item 1A. Risk Factors
We do not believe there have been any material changes 
in  our  risk  factors  since  the  filing  of  our  Annual  Report 
on  Form  10-K  for  the  fiscal  year  ended  September  30, 
2009.  However,  we  may  update  our  risk  factors  in  our 
SEC  filings  from  time  to  time  for  clarification  purposes 
or  to  include  additional  information,  at  management’s 
discretion,  even  when  there  have  been  no  material 
changes.

Risks Relating to Our Business

Demand for Our Products Fluctuates and Our 
Business May Be Adversely Affected by Worldwide 
Economic and Industry Conditions
Our business is affected by economic and industry con-
ditions  and  our  revenue  is  dependent  upon  semicon-
ductor  demand.  Semiconductor  demand,  in  turn,  is 
impacted  by  semiconductor  industry  cycles,  and  these 
cycles can dramatically affect our business. These cycles 
may be characterized by rapid increases or decreases in 
product  demand,  excess  or  low  customer  inventories, 
and rapid changes in prices of IC devices. In the first half  

of fiscal 2009, our business was significantly impacted by 
the  global  economic  recession.  We  first  began  to  see 
significant adverse effects of this in our fourth quarter of 
fiscal  2008  as  the  reduction  in  end  user  demand  for  
IC  devices  caused  semiconductor  manufacturers  to 
reduce their production, which reduced the demand for 
our  CMP  consumables  products.  Weakness  in  the  U.S. 
and global economy and stress in the financial markets 
caused  a  significant  decrease  in  demand  for  our  prod-
ucts during the first half of fiscal 2009, and our revenue 
decreased  dramatically  from  revenue  earned  in  fiscal 
2008.  Demand  for  our  products  increased  significantly 
during the second half of fiscal 2009 and this strength in 
demand  continued  throughout  fiscal  2010.  While  we  
continue to see positive signs of growth in the semicon-
ductor industry, it is difficult to predict trends due to our 
limited visibility to future customer orders. If the global 
economy  falters  and  conditions  begin  to  deteriorate 
again, we could experience material adverse impacts on 
our results of operations and financial condition.

Adverse  global  economic  conditions  may  have  other 
negative effects on our Company such as:

•   The ability of our customers to pay their obligations to 
us  may  be  adversely  affected  causing  a  negative 
impact on our cash flows and our results of operations 
as evidenced by the bankruptcy filings of a small num-
ber of our customers in fiscal 2009.

•   The carrying value of our goodwill and other intangi-
ble assets may decline in value, which could harm our 
financial position and results of operations.

•   Our  suppliers  may  not  be  able  to  fulfill  their  obliga-
tions to us, which could harm our production process 
and our business.

Some  additional  factors  that  affect  demand  for  our 
products include customers’ production of logic versus 
memory  devices,  customers’  specific  manufacturing 
process  integration  schemes,  share  gains  and  losses 
and pricing changes by us and our competitors.

We Have a Narrow Product Range and Our 
Products May Become Obsolete, or Technological 
Changes May Reduce or Limit Increases in the 
Consumption of CMP Slurries and Pads
Our  business  is  substantially  dependent  on  a  single 
class  of  products,  CMP  slurries,  which  account  for  the 
majority  of  our  revenue.  Our  business  in  CMP  pads  is 
also developing and growing. Our business would suffer 
if  these  products  became  obsolete  or  if  consumption  
of these products decreased. Our success depends on 
our ability to keep pace with technological changes and 
advances  in  the  semiconductor  industry  and  to  adapt, 
improve  and  customize  our  products  for  advanced  IC 
applications  in  response  to  evolving  customer  needs 
and  industry  trends.  Since  its  inception,  the  semicon-
ductor  industry  has  experienced  rapid  technological 

10

11

changes and advances in the design, manufacture, per-
formance  and  application  of  IC  devices,  and  our  cus-
tomers  continually  pursue  lower  cost  of  ownership  of 
materials  consumed  in  their  manufacturing  processes, 
including CMP slurries and pads. We expect these tech-
nological changes and advances, and this drive toward 
lower costs, will continue in the future. Potential technol-
ogy  developments  in  the  semiconductor  industry,  as 
well as our customers’ efforts to reduce consumption of 
CMP  consumables  and  to  possibly  reuse  or  recycle 
these  products,  could  render  our  products  less  impor-
tant to the IC device manufacturing process.

A Significant Amount of Our Business Comes from 
a Limited Number of Large Customers and Our 
Revenue and Profits Could Decrease Significantly  
if We Lost One or More of These Customers
Our  customer  base  is  concentrated  among  a  limited 
number of large customers. One or more of these prin-
cipal  customers  could  stop  buying  CMP  consumables 
from  us  or  could  substantially  reduce  the  quantity  of 
CMP  consumables  purchased  from  us.  Our  principal 
customers  also  hold  considerable  purchasing  power, 
which  can  impact  the  pricing  and  terms  of  sale  of  our 
products.  Any  deferral  or  significant  reduction  in  CMP 
consumables sold to these principal customers, or a sig-
nificant  number  of  smaller  customers,  could  seriously 
harm  our  business,  financial  condition  and  results  of 
operations.

In  fiscal  2010,  our  five  largest  customers  accounted  for 
approximately  48%  of  our  revenue,  with  Taiwan  Semi-
conductor Manufacturing Company (TSMC) and United 
Microelectronics  Corporation  (UMC)  accounting  for 
approximately 18% and 11%, respectively, of our revenue. 
In  fiscal  2009,  our  five  largest  customers  accounted  for 
approximately 42% of our revenue; with TSMC account-
ing for approximately 17% of our revenue. UMC accounted 
for less than 10% of our revenue in fiscal 2009.

Our Business Could Be Seriously Harmed if Our 
Competitors Develop Superior Slurry Products, 
Offer Better Pricing Terms or Service, or Obtain 
Certain Intellectual Property Rights
Competition from other CMP slurry manufacturers could 
seriously  harm  our  business  and  results  of  operations. 
Competition from other providers of CMP slurries could 
continue  to  increase,  and  opportunities  exist  for  other 
companies  to  emerge  as  potential  competitors  by 
developing  their  own  CMP  slurry  products.  Increased 
competition has and may continue to impact the prices 
we are able to charge for our slurry products as well as 
our overall business. In addition, our competitors could 
have  or  obtain  intellectual  property  rights  which  could 
restrict our ability to market our existing products and/
or to innovate and develop new products.

Any Problem or Disruption in Our Supply Chain, 
Including Supply of Our Most Important Raw 
Materials, or in Our Ability to Manufacture and 
Deliver Our Products to Our Customers, Could 
Adversely Affect Our Results of Operations
We  depend  on  our  supply  chain  to  enable  us  to  meet 
the  demands  of  our  customers.  Our  supply  chain 
includes  the  raw  materials  we  use  to  manufacture  our 
products, our production operations, and the means by 
which  we  deliver  our  products  to  our  customers.  Our 
business could be adversely affected by any problem or 
interruption  in  our  supply  of  the  key  raw  materials  we 
use in our CMP slurries and pads, including fumed silica, 
which we use for certain of our slurries, or any problem 
or  interruption  that  may  occur  during  production  or 
delivery of our products, such as weather-related prob-
lems or natural disasters.

For  instance,  Cabot  Corporation  continues  to  be  our 
primary  supplier  of  particular  amounts  and  types  of 
fumed silica. We believe it would be difficult to promptly 
secure  alternative  sources  of  key  raw  materials,  includ-
ing  fumed  silica,  in  the  event  one  of  our  suppliers 
becomes  unable  to  supply  us  with  sufficient  quantities 
of  raw  materials  that  meet  the  quality  and  technical 
specifications  required  by  our  customers.  In  addition, 
contractual  amendments  to  the  existing  agreements 
with,  or  non-performance  by,  our  suppliers,  including 
any significant financial distress our suppliers may suffer, 
could  adversely  affect  us.  Also,  if  we  change  the  sup-
plier  or  type  of  key  raw  materials  we  use  to  make  our 
CMP slurries or pads, or are required to purchase them 
from  a  different  manufacturer  or  manufacturing  facility 
or  otherwise  modify  our  products,  in  certain  circum-
stances our customers might have to requalify our CMP 
slurries and pads for their manufacturing processes and 
products.  The  requalification  process  could  take  a  sig-
nificant  amount  of  time  and  expense  to  complete  and 
could  motivate  our  customers  to  consider  purchasing 
products  from  our  competitors,  possibly  interrupting  
or  reducing  our  sales  of  CMP  consumables  to  these 
customers.

We Are Subject to Risks Associated With Our 
Foreign Operations
We currently have operations and a large customer base 
outside  of  the  United  States.  Approximately  86%,  84% 
and 81% of our revenue was generated by sales to cus-
tomers outside of the United States for fiscal 2010, 2009 
and  2008,  respectively.  We  encounter  risks  in  doing 
business in certain foreign countries, including, but not 
limited  to,  adverse  changes  in  economic  and  political 
conditions,  fluctuation  in  exchange  rates,  compliance 
with a variety of foreign laws and regulations, as well as 
difficulty  in  enforcing  business  and  customer  contracts 
and  agreements,  including  protection  of  intellectual 
property rights.

We May Pursue Acquisitions of, Investments in, and 
Strategic Alliances with Other Entities, Which Could 
Disrupt Our Operations and Harm Our Operating 
Results if They Are Unsuccessful
We expect to continue to make investments in compa-
nies,  either  through  acquisitions,  investments  or  alli-
ances,  in  order  to  supplement  our  internal  growth  and 
development  efforts.  Acquisitions  and  investments, 
including  our  acquisition  of  Epoch  Material  Co.,  Ltd.,  a 
Taiwan-based  company,  the  first  closing  of  which  we 
completed  in  the  fiscal  quarter  ended  March  31,  2009 
and the final closing of which we completed in the fiscal 
quarter  ended  September  30,  2010,  involve  numerous 
risks,  including  the  following:  difficulties  in  integrating 
the  operations,  technologies,  products  and  personnel 
of  acquired  companies;  diversion  of  management’s 
attention from normal daily operations of the business; 
increased risk associated with foreign operations; poten-
tial difficulties in entering markets in which we have lim-
ited or no direct prior experience and where competitors 
in such markets have stronger market positions; poten-
tial  difficulties  in  operating  new  businesses  with  dif-
ferent  business  models;  potential  difficulties  with 
regulatory  or  contract  compliance  in  areas  in  which  we 
have limited experience; initial dependence on unfamil-
iar  supply  chains  or  relatively  small  supply  partners; 
insufficient revenues to offset increased expenses asso-
ciated with acquisitions; potential loss of key employees 
of  the  acquired  companies;  or  inability  to  effectively 
cooperate and collaborate with our alliance partners.

Further,  we  may  never  realize  the  perceived  or  antici-
pated  benefits  of  a  business  combination  or  invest-
ments  in  other  entities.  Acquisitions  by  us  could  have 
negative  effects  on  our  results  of  operations,  in  areas 
such as contingent liabilities, gross profit margins, amor-
tization  charges  related  to  intangible  assets  and  other 
effects of accounting for the purchases of other business 
entities. Investments in and acquisitions of technology-
related  companies  are  inherently  risky  because  these 
businesses may never develop, and we may incur losses 
related  to  these  investments.  In  addition,  we  may  be 
required  to  write  down  the  carrying  value  of  these 
acquisitions or investments to reflect other than tempo-
rary declines in their value, which could  harm our  busi-
ness and results of operations.

Because We Have Limited Experience in Business 
Areas Outside of CMP Slurries, Expansion of Our 
Business into New Products and Applications May 
Not Be Successful
An  element  of  our  strategy  has  been  to  leverage  our 
current customer relationships and technological exper-
tise to expand our CMP business from CMP slurries into 
other  areas,  such  as  CMP  polishing  pads.  Additionally, 
pursuant  to  our  Engineered  Surface  Finishes  business, 
we are pursuing other surface modification applications. 

Expanding  our  business  into  new  product  areas  could 
involve  technologies,  production  processes  and  busi-
ness  models  in  which  we  have  limited  experience,  and 
we  may  not  be  able  to  develop  and  produce  products 
or provide services that satisfy customers’ needs or we 
may be unable to keep pace with technological or other 
developments.  Also,  our  competitors  may  have  or 
obtain  intellectual  property  rights  which  could  restrict 
our  ability  to  market  our  existing  products  and/or  to 
innovate and develop new products.

Because We Rely Heavily on Our Intellectual 
Property, Our Failure to Adequately Obtain or 
Protect It Could Seriously Harm Our Business
Protection of intellectual property is particularly impor-
tant in our industry because we develop complex tech-
nical formulas for CMP products that are proprietary in 
nature and differentiate our products from those of our 
competitors.  Our  intellectual  property  is  important  to 
our success and ability to compete. We attempt to pro-
tect our intellectual property rights through a combina-
tion  of  patent,  trademark,  copyright  and  trade  secret 
laws, as well as employee and third-party nondisclosure 
and  assignment  agreements.  Due  to  our  international 
operations,  we  pursue  protection  in  different  jurisdic-
tions, which may provide varying degrees of protection, 
and  we  cannot  provide  assurance  that  we  can  obtain 
adequate  protection  in  each  such  jurisdiction.  Our  fail-
ure  to  obtain  or  maintain  adequate  protection  of  our 
intellectual  property  rights  for  any  reason,  including 
through the patent prosecution process or in the event 
of  litigation  related  to  such  intellectual  property,  such  
as  the  current  litigation  between  us  and  DuPont  Air 
Products NanoMaterials (DA Nano), in which the validity 
of all of our patents at issue in the matter was recently 
upheld as further described above in Part I, Item 1 under 
the heading “Intellectual Property” and in Part I, Item 3 
under the heading “Legal Proceedings,” could seriously 
harm our business. In addition, the costs of obtaining or 
protecting  our  intellectual  property  could  negatively 
affect our operating results. For example, in fiscal 2010, 
costs associated with enforcing our intellectual property 
caused our operating expenses to increase.

We May Not Be Able to Monetize Our Investments 
in Auction Rate Securities in the Short Term and We 
Could Experience a Decline in Their Market Value, 
Which Could Adversely Affect Our Financial Results
We  owned  auction  rate  securities  (ARS)  with  an  esti-
mated fair value of $8.1 million ($8.3 million par value) at 
September  30,  2010,  which  were  classified  as  Other 
Long-Term Assets on our Consolidated Balance Sheet. If 
current  illiquidity  in  the  ARS  market  does  not  lessen,  if 
issuers of our ARS are unable to refinance the underly-
ing securities, or are unable to pay debt obligations and 
related  bond  insurance  fails,  or  if  credit  ratings  decline 
or  other  adverse  developments  occur  in  the  credit 

12

13

markets,  then  we  may  not  be  able  to  monetize  these 
securities  in  the  foreseeable  future.  We  may  also  be 
required  to  further  adjust  the  carrying  value  of  these 
instruments through an impairment charge that may be 
deemed  other-than-temporary  which  would  adversely 
affect our financial results.

Our Inability to Attract and Retain Key Personnel 
Could Cause Our Business to Suffer
If we fail to attract and retain the necessary managerial, 
technical and customer support personnel, our business 
and our ability to maintain existing and obtain new cus-
tomers, develop new products and provide acceptable 
levels  of  customer  service  could  suffer.  We  compete 
with other industry participants for qualified personnel, 
particularly  those  with  significant  experience  in  the 
semiconductor  industry.  The  loss  of  services  of  key 
employees  could  harm  our  business  and  results  of 
operations.

Risks Relating to the Market for Our  
Common Stock

The Market Price May Fluctuate Significantly  
and Rapidly
The  market  price  of  our  common  stock  has  fluctuated 
and  could  continue  to  fluctuate  significantly  as  a  result 
of  factors  such  as:  economic  and  stock  market  con-
ditions  generally  and  specifically  as  they  may  impact 
participants  in  the  semiconductor  and  related  indus-
tries;  changes  in  financial  estimates  and  recommen-
dations  by  securities  analysts  who  follow  our  stock; 
earnings and other announcements by, and changes in 
market evaluations of, us or participants in the semicon-
ductor  and  related  industries;  changes  in  business  or 
regulatory conditions affecting us or participants in the 
semiconductor  and  related  industries;  announcements 
or  implementation  by  us,  our  competitors,  or  our  cus-
tomers  of  technological  innovations,  new  products  or 
different business strategies; and trading volume of our 
common stock.

Anti-Takeover Provisions Under Our Certificate  
of Incorporation and Bylaws May Discourage  
Third Parties from Making an Unsolicited Bid  
for Our Company
Our certificate of incorporation, our bylaws, and various 
provisions  of  the  Delaware  General  Corporation  Law 
may  make  it  more  difficult  or  expensive  to  effect  a 
change  in  control  of  our  Company.  For  instance,  our 
amended and restated certificate of incorporation pro-
vides for the division of our Board of Directors into three 
classes as nearly equal in size as possible with staggered 
three-year  terms.  Until  April  2010,  we  had  a  rights  plan 
which expired according to the terms of the plan.

We have adopted change in control arrangements cov-
ering  our  executive  officers  and  other  key  employees. 
These  arrangements  provide  for  a  cash  severance  pay-
ment,  continued  medical  benefits  and  other  ancillary 
payments and benefits upon termination of service of a 
covered employee’s employment following a change in 
control,  which  may  make  it  more  expensive  to  acquire 
our Company.

Item 1B. Unresolved Staff Comments
None.

Item 2. Properties
Our principal U.S. facilities that we own consist of:

•   A global headquarters and research and development 
facility  in  Aurora,  Illinois,  comprising  approximately 
200,000 square feet;

•   A commercial dispersion plant and distribution center 
in  Aurora,  Illinois,  comprising  approximately  175,000 
square feet;

•   A commercial polishing pad manufacturing plant and 
offices  in  Aurora,  Illinois,  comprising  approximately 
48,000 square feet;

•   An additional 13.2 acres of vacant land in Aurora, Illinois; 

and

•   A facility in Addison, Illinois, comprising approximately 

15,000 square feet.

In  addition,  we  lease  a  facility  in  Rochester,  New  York, 
comprising approximately 21,000 square feet.

Our principal foreign facilities that we or our subsidiaries 
own consist of:

•   A  commercial  dispersion  plant,  automated  ware-
house,  research  and  development  facility  and  offices 
in  Kaohsiung  County,  Taiwan,  comprising  approxi-
mately 170,000 square feet;

•   A commercial dispersion plant and distribution center 
in Geino, Japan, comprising approximately 113,000 
square feet;

•   A development and technical support facility in Geino, 
Japan, comprising approximately 20,000 square feet.

Our principal foreign facilities that we lease consist of:

•   An  office,  research  and  development  laboratory  and 
polishing  pad  manufac turing  plant  in  Hsin-Chu, 
Taiwan, comprising approximately 31,000 square feet;

•   A  commercial  manufacturing  plant,  research  and 
development facility and business office in Singapore, 
comprising approximately 24,000 square feet.

We believe that our facilities are suitable and adequate 
for their intended purpose and provide us with sufficient 
capacity  and  capacity  expansion  opportunities  and 
technological  capability  to  meet  our  current  and 
expected  demand  in  the  foreseeable  future.  In  fiscal 
2011,  we  plan  to  increase  our  manufacturing  capacity 
and add new capabilities in the Asia Pacific region. For 
example, we recently announced we have entered into a 
non-binding  memorandum  of  understanding  (MOU) 
with  the  Gyeonggi  Province  of  South  Korea  to  poten-
tially  establish  manufacturing  and  research  and  devel-
opment capabilities there. The MOU reflects a potential 
aggregate  investment  of  approximately  $10  million  in 
Gyeonggi Province. In addition, we plan to expand our 
Geino, Japan dispersions plant to increase our manufac-
turing production capacity there.

Item 3. Legal Proceedings
While we are not involved in any legal proceedings that 
we  believe  will  have  a  material  impact  on  our  consoli-
dated  financial  position,  results  of  operations  or  cash 
flows, we periodically become a party to legal proceed-
ings in the ordinary course of business. For example, in 
January 2007, we filed a legal action against DuPont Air 
Products  NanoMaterials  LLC  (DA  Nano),  a  CMP  slurry 

competitor,  in  the  United  States  District  Court  for  the 
District of Arizona, charging that DA Nano’s manufactur-
ing and marketing of CMP slurries infringe certain CMP 
slurry patents that we own. The affected DA Nano prod-
ucts  include  certain  products  used  for  tungsten  CMP. 
We  filed  our  infringement  complaint  as  a  counterclaim 
in response to an action filed by DA Nano in the same 
court  in  December  2006  that  sought  declaratory  relief 
and alleged non-infringement, invalidity and unenforce-
ability  regarding  some  of  the  patents  at  issue  in  our 
complaint against DA Nano. DA Nano filed its complaint 
following  our  refusal  of  its  request  that  we  license  to  it 
our patents raised in its complaint. DA Nano’s complaint 
did not allege any infringement by our products of intel-
lectual  property  owned  by  DA  Nano.  From  June  14 
through  July  8,  2010,  a  jury  trial  for  the  case  was  held.  
All  of  Cabot  Microelectronics’  patents  at  issue  in  the 
case were found valid. However, the jury found that DA 
Nano’s  products  at  issue  do  not  infringe  the  asserted 
claims  of  these  patents.  In  November  2010,  we  filed  a 
Notice of Appeal regarding infringement, and DA Nano 
filed a cross-appeal. While the outcome of this and any 
legal matter cannot be predicted with certainty, we con-
tinue  to  believe  that  our  claims  and  defenses  in  the 
pending  action  are  meritorious,  and  we  intend  to  con-
tinue to pursue and defend them.

In  January  2008,  we  announced  that  our  Board  of 
Directors  had  authorized  a  share  repurchase  program 
for up to $75.0 million of our outstanding common stock. 
Shares  are  repurchased  from  time  to  time,  depending 
on  market  conditions,  in  open  market  transactions,  at 
management’s  discretion.  We  fund  share  repurchases 
from  our  existing  cash  balance.  The  program,  which 
became  effective  on  the  authorization  date,  may  be  
suspended or terminated at any time, at the Company’s 
discretion.  During  the  fiscal  year  ended  September  
30,  2010,  we  repurchased  a  total  of  723,184  shares  for  
$25.0 million.

Separate from this share repurchase program, a total of 
24,651 shares were purchased during fiscal 2010 pursu-
ant to the terms of our Second Amended and Restated 
Cabot Microelectronics Corporation 2000 Equity Incen-
tive  Plan  (EIP)  as  shares  withheld  from  award  recipients 
to  cover  payroll  taxes  on  the  vesting  of  shares  of 
restricted  stock  granted  under  the  EIP.  No  shares  were 
purchased under the EIP during the fiscal quarter ended 
September 30, 2010.

Item 7.  Management’s Discussion and 

Analysis of Financial Condition and  
Results of Operations

The  following  “Management’s  Discussion  and  Analysis 
of  Financial  Condition  and  Results  of  Operations,”  as 
well as disclosures included elsewhere in this Form 10-K, 
include “forward-looking statements” within the mean-
ing  of  the  Private  Securities  Litigation  Reform  Act  of 
1995. This Act provides a safe harbor for forward-looking 
statements  to  encourage  companies  to  provide  pro-
spective  information  about  themselves  so  long  as  
they  identify  these  statements  as  forward-looking  and 
provide  meaningful  cautionary  statements  identifying 
important factors that could cause actual results to dif-
fer from the projected results. All statements other than 
statements of historical fact we make in this Form 10-K 
are forward-looking. In particular, the statements herein 
regarding  future  sales  and  operating  results;  Company 
and  industry  growth,  contraction  or  trends;  growth  or 
contraction  of  the  markets  in  which  the  Company  par-
ticipates;  international  events  or  various  economic  fac-
tors;  product  performance;  the  generation,  protection 
and  acquisition  of  intellectual  property,  and  litigation 
related to such intellectual property; new product intro-
ductions;  development  of  new  products,  technologies 
and  markets;  the  acquisition  of  or  investment  in  other 
entities;  uses  and  investment  of  the  Company’s  cash 
balance;  the  construction  of  facilities  by  the  Company; 
and statements preceded by, followed by or that include 
the  words  “intends,”  “estimates,”  “plans,”  “believes,” 
“expects,” “anticipates,” “should,” “could” or similar 
expressions,  are  forward-looking  statements.  Forward-
looking statements reflect our current expectations and 
are  inherently  uncertain.  Our  actual  results  may  differ 
significantly from our expectations. We assume no obli-
gation  to  update  this  forward-looking  information.  The 
section entitled “Risk Factors” describes some, but not 
all, of the factors that could cause these differences.

The following discussion and analysis should be read in 
conjunction with our historical financial statements and 
the  notes  to  those  financial  statements  which  are 
included in Item 8 of Part II of this Form 10-K.

Overview
Cabot Microelectronics Corporation (“Cabot Microelec-
tronics”,  “the  Company”,  “us”,  “we”,  or  “our”)  is  the 
leading  supplier  of  high-performance  polishing  slurries 
and  a  growing  pad  supplier  used  in  the  manufacture  
of  advanced  integrated  circuit  (IC)  devices  within  the 
semiconductor  industry,  in  a  process  called  chemical 
mechanical  planarization  (CMP).  CMP  is  a  polishing 
proc ess used by IC device manufacturers to planarize or 
flatten  many  of  the  multiple  layers  of  material  that  are 
deposited  upon  silicon  wafers  in  the  production  of 
advanced  ICs.  Our  products  play  a  critical  role  in  the 

production  of  advanced  IC  devices,  thereby  enabling 
our  customers  to  produce  smaller,  faster  and  more  
complex IC devices with fewer defects. Demand for our  
CMP  products  is  primarily  driven  by  the  number  of 
wafers processed by semiconductor manufacturers, the 
first  manufacturing  step  of  which  is  referred  to  as  a 
“wafer start.”

We  operate  predominantly  in  one  industry  segment—
the  development,  manufacture  and  sale  of  CMP  con-
sumables.  We  develop,  produce  and  sell  CMP  slurries 
for  polishing  many  of  the  conducting  and  insulating 
materials used in IC devices, and also for polishing cer-
tain  components  in  hard  disk  drives,  specifically  rigid 
disk  substrates  and  magnetic  heads.  In  addition,  we 
develop,  manufacture  and  sell  CMP  polishing  pads, 
which  are  used  in  conjunction  with  slurries  in  the  CMP 
process. We also pursue a number of other demanding 
surface  modification  applications  outside  of  the  semi-
conductor  and  hard  disk  drive  industries  through  our 
Engineered  Surface  Finishes  (ESF)  business,  for  which 
we believe our capabilities and knowledge may provide 
value in improved surface performance or productivity.

The  improvement  in  economic  and  industry  conditions 
that we began to see in our business during the second 
half of fiscal 2009, following the severe global recession, 
continued  through  our  fiscal  2010  and  positively 
impacted demand for our products. We continue to see 
positive signs of growth in the semiconductor industry: 
reports from customers indicate utilization of fab capac-
ity is currently at an all-time high; inventory levels of IC 
devices  appear  to  be  within  an  appropriate  range;  and 
significant  capacity  expansion  activity  by  a  number  of 
semiconductor  device  manufacturers  is  underway. 
However, we remain cautious regarding future demand 
trends over the near term as the first quarter of the cal-
endar year typically demonstrates softer demand due to 
seasonal  variations  within  the  semiconductor  industry. 
There  are  many  factors,  that  make  it  difficult  for  us  to 
predict  future  revenue  trends  for  our  business,  includ-
ing:  the  pace,  timing  and  sustainability  of  the  ongoing 
economic  recovery;  the  cyclical  nature  of  the  semicon-
ductor industry; the short order to delivery time for our 
products  and  the  associated  lack  of  visibility  to  future 
customer orders; quarter to quarter changes in our rev-
enue  regardless  of  industry  strength;  and  potential 
future acquisitions by us.

Revenue for fiscal 2010 was $408.2 million, which repre-
sented  an  increase  of  40.1%  from  the  $291.4  million 
reported  for  fiscal  2009.  The  increase  in  revenue  from 
fiscal  2009  reflects  increased  sales  volume  due  to 
improved economic and semiconductor industry condi-
tions. We experienced significant revenue growth across 
all  of  our  product  lines,  including  a  68.9%  increase  in 
revenue  from  our  polishing  pad  products  and  a  53.9%  

20

21

increase  in  revenue  from  copper  slurries,  which  bene-
fited from a full year impact in fiscal 2010 of our February 
2009 acquisition of Epoch Material Co., Ltd. (Epoch) ver-
sus only a partial year benefit in the prior fiscal year.

Gross  profit  expressed  as  a  percentage  of  revenue  for 
fiscal 2010 was 49.9%, which represents an increase from 
the 44.1% reported for fiscal 2009. The increase in gross 
profit percentage from fiscal 2009 was primarily due to 
the  significant  increase  in  sales  volume  due  to  contin-
ued improvement in economic and industry conditions, 
and  the  related  benefits  of  increased  utilization  of  our 
manufacturing  capacity,  partially  offset  by  higher  fixed 
manufacturing costs and unfavorable foreign exchange 
effects.  We  expect  our  gross  profit  percentage  for  full 
year  fiscal  2011  to  be  in  the  range  of  48%  to  50%. 
However,  we  may  experience  fluctuations  in  our  gross 
profit  due  to  a  number  of  factors,  including  the  extent 
to which we utilize our manufacturing capacity and fluc-
tuations in our product mix, which may cause our quar-
terly gross profit to be above or below this range.

Operating  expenses  of  $129.5  million,  which  include 
research,  development  and  technical,  selling  and  mar-
keting,  and  general  and  administrative  expenses, 
increased 15.2%, or $17.1 million, from the $112.4 million 
reported for fiscal 2009. The increase was primarily due 
to  higher  staffing-related  costs,  including  costs  associ-
ated with our annual incentive bonus program, and the 
reinstatement  of  certain  employee  benefits  that  were 
suspended  during  the  economic  downturn  in  fiscal 
2009, higher professional fees, including costs to enforce 
our  intellectual  property  as  discussed  in  the  following 
paragraph,  higher  travel-related  expenses,  and  a  full 
year  of  Epoch  operating  expenses  included  in  fiscal 
2010  versus  only  a  partial  year  in  fiscal  2009.  In  fiscal 
2011, we expect our full year operating expenses to be 
in the range of $125 million to $130 million.

In  July  2010,  a  jury  trial  was  completed  in  connection 
with  our  ongoing  patent  enforcement  litigation  against 
DuPont Air Products NanoMaterials LLC (DA Nano). We 
were pleased that the validity of our patents at issue was 
upheld with the jury’s verdict; however, we were disap-
pointed  that  the  jury  did  not  find  DA  Nano’s  products  
at  issue  infringed  the  asserted  claims  of  our  patents.  
In November 2010, we filed a Notice of Appeal regard-
ing  infringement,  and  DA  Nano  filed  a  cross-appeal. 
Expenses  related  to  this  trial  caused  our  operating 
expenses  to  increase  in  fiscal  2010.  Now  that  the  jury 
trial phase has been completed, we expect our litigation 
costs  related  to  this  matter  to  decrease  significantly  in 
fiscal  2011,  as  they  did  in  the  fourth  quarter  of  fiscal 
2010.  See  Part  I,  Item  3  entitled  “Legal  Proceedings” 
and Note 17 of the Notes to the Consolidated Financial 
Statements for more information on the enforcement of 
our intellectual property.

Diluted  earnings  per  share  of  $2.13  in  fiscal  2010 
increased 343.8%, or $1.65, from $0.48 reported in fiscal 
2009 as a result of the factors discussed above. Diluted 
earnings  per  share  were  positively  impacted  by  our 
election in fiscal 2010 to permanently reinvest the earn-
ings  of  certain  of  our  foreign  subsidiaries  outside  
the U.S. rather than repatriating the earnings to the U.S. 
This  election,  which  was  made  in  the  fourth  quarter  of 
fiscal  2010,  reduced  our  effective  income  tax  rate  for  
the  year  from  35.2%  to  32.5%  and  increased  diluted 
earnings per share by $0.09. In fiscal 2011, we expect our 
full  year  effective  income  tax  rate  to  be  in  the  range  
of  31%  to  33%.  See  Note  16  of  the  Notes  to  the 
Consolidated  Financial  Statements  for  further  discus-
sion on income taxes.

Critical Accounting Policies and Estimates
This “Management’s Discussion and Analysis of Financial 
Condition  and  Results  of  Operations”  (MD&A),  as  well 
as disclosures included elsewhere in this Form 10-K, are 
based  upon  our  audited  consolidated  financial  state-
ments,  which  have  been  prepared  in  accordance  with 
accounting  principles  generally  accepted  in  the  United 
States.  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  contingencies.  On 
an  ongoing  basis,  we  evaluate  the  estimates  used, 
including  those  related  to  bad  debt  expense,  warranty 
obligations, inventory valuation, valuation and classifica-
tion of auction rate securities, impairment of long-lived 
assets  and  investments,  business  combinations,  good-
will, other intangible assets, share-based compensation, 
income taxes and contingencies. We base our estimates 
on historical experience, current conditions and on vari-
ous 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  are  not  readily  apparent  from 
other  sources,  as  well  as  for  identifying  and  assessing 
our accounting treatment with respect to commitments 
and contingencies. Actual results may differ from these 
estimates  under  different  assumptions  or  conditions. 
We  believe  the  following  critical  accounting  policies 
involve significant judgments and estimates used in the 
preparation of our consolidated financial statements.

Allowance for Doubtful Accounts
We maintain an allowance for doubtful accounts for esti-
mated  losses  resulting  from  the  potential  inability  of  
our  customers  to  make  required  payments.  Our  allow-
ance  for  doubtful  accounts  is  based  on  historical  col-
lection  experience,  adjusted  for  any  specific  known 
conditions or circumstances. While historical experience  

20

21

may  provide  a  reasonable  estimate  of  uncollectible 
accounts,  actual  results  may  differ  from  what  was 
recorded.  The  global  economic  recession  adversely 
affected  our  ability  to  collect  accounts  receivable  from 
some of our customers in fiscal 2009. The recession also 
caused a small number of our customers to file for bank-
ruptcy or insolvency. We recorded a $0.9 million increase 
in  our  allowance  for  doubtful  accounts  during  fiscal 
2009  to  account  for  these  bankruptcies  and  the 
increased risk regarding customer collections due to the 
continued  uncertainty  in  the  global  economy.  We  will 
continue  to  monitor  the  financial  solvency  of  our  cus-
tomers  and,  if  global  economic  conditions  worsen,  we 
may  have  to  record  additional  increases  to  our  allow-
ances for doubtful accounts. As of September 30, 2010, 
our  allowance  for  doubtful  accounts  represented  1.9% 
of  gross  accounts  receivable.  If  we  had  increased  our 
estimate of bad debts to 2.9% of gross accounts receiv-
able,  our  general  and  administrative  expenses  would 
have increased by $0.6 million.

Warranty Reserve
We  maintain  a  warranty  reserve  that  reflects  manage-
ment’s  best  estimate  of  the  cost  to  replace  product  
that  does  not  meet  customers’  specifications  and  per-
formance  requirements,  and  costs  related  to  such 
replacement.  The  warranty  reserve  is  based  upon  a  
historical  product  replacement  rate,  adjusted  for  any 
specific  known  conditions  or  circumstances.  Should 
actual  warranty  costs  differ  substantially  from  our  esti-
mates,  revisions  to  the  estimated  warranty  liability  may 
be  required.  As  of  September  30,  2010,  our  warranty 
reserve  represented  0.3%  of  the  current  quarter  reve-
nue. If  we had increased our warranty  reserve estimate 
to 1.3% of the current quarter revenue, our cost of goods 
sold would have increased by $1.1 million.

Inventory Valuation
We  value  inventory  at  the  lower  of  cost  or  market  and 
write down the value of inventory for estimated obsoles-
cence or if inventory is deemed unmarketable. An inven-
tory  reserve  is  maintained  based  upon  a  historical 
percentage  of  actual  inventories  written  off  applied 
against  the  inventory  value  at  the  end  of  the  period, 
adjusted  for  known  conditions  and  circumstances.  We 
exercise  judgment  in  estimating  the  amount  of  inven-
tory  that  is  obsolete.  Should  actual  product  market-
ability and fitness for use be affected by conditions that 
are  different  from  those  projected  by  management, 
revisions  to  the  estimated  inventory  reserve  may  be 
required.  If  we  had  increased  our  reserve  for  obsolete 
inventory  at  September  30,  2010  by  10%,  our  cost  of 
goods sold would have increased by $0.2 million.

Valuation and Classification of  
Auction Rate Securities
As  of  September  30,  2010,  we  owned  two  auction  rate 
securities (ARS) with an estimated fair value of $8.1 mil-
lion ($8.3 million par value) which are classified as other 
long-term  assets  on  our  Consolidated  Balance  Sheet.  
In  general,  ARS  investments  are  securities  with  long-
term nominal maturities for which interest rates are reset 
through a Dutch auction every seven to 35 days. Histor-
ically,  these  periodic  auctions  provided  a  liquid  market 
for these securities. General uncertainties in the global 
credit  markets  during  2008  caused  widespread  ARS 
auction  failures  as  the  number  of  securities  submitted 
for sale exceeded the number of securities buyers were 
willing to purchase, and these auction failures have con-
tinued.  As  a  result,  the  short-term  liquidity  of  the  ARS 
market has been adversely affected since then.

As  discussed  in  Notes  4  and  8  of  the  Notes  to  the 
Consolidated Financial Statements, we have recorded a 
temporary impairment of $0.2 million, net of tax, in the 
value of one of our ARS in other comprehensive income. 
The calculation of fair value and the balance sheet clas-
sification  for  our  ARS  requires  critical  judgments  and 
estimates  by  management  including  an  appropriate  
discount  rate  and  the  probabilities  that  a  security  may 
be  monetized  through  a  future  successful  auction,  of  a 
refinancing  of  the  underlying  debt,  of  a  default  in  pay-
ment  by  the  issuer,  and  of  payments  not  being  made  
by the bond insurance carrier in the event of default by 
the  issuer.  In  fiscal  2009,  we  adopted  new  accounting 
pronouncements regarding the classification and valua-
tion  of  financial  instruments.  These  pronouncements 
discuss the recognition and presentation of other-than-
temporary  impairments  and  the  determination  of  fair 
value of financial instruments when the volume of trad-
ing activity significantly drops. An other-than-temporary 
impairment must be recorded when a credit loss exists; 
that  is  when  the  present  value  of  the  expected  cash 
flows  from  a  debt  security  is  less  than  the  amortized 
cost basis of the security. We performed two discounted 
cash flow analyses, one using a discount rate based on a 
market  index  comprised  of  tax  exempt  variable  rate 
demand  obligations  and  one  using  a  discount  rate 
based on the LIBOR swap curve, and we applied a risk 
factor to reflect current liquidity issues in the ARS mar-
ket.  We  then  assigned  probabilities  of  holding  each 
security for less than or equal to one year, five years, and 
to maturity to calculate a fair value for each security. We 
also considered the probability of default in payment by 
the issuer of the securities, the strength of the insurance 
backing  and  the  probability  of  failure  by  the  insurance  

22

23

carrier in the case of default by the issuer of the securi-
ties. The impairment we have maintained is considered 
temporary as it relates to the loss of liquidity in the ARS 
market and does not represent a credit loss. We do not 
intend to sell the securities at a loss and we believe we 
will not be required to sell the securities at a loss in the 
future. If auctions involving our remaining ARS continue 
to fail, if issuers of our ARS are unable to refinance the 
underlying  securities,  if  the  issuing  municipalities  are 
unable to pay their debt obligations and the bond insur-
ance  fails,  or  if  credit  ratings  decline  or  other  adverse 
developments  occur  in  the  credit  markets,  we  may  not 
be able to monetize our remaining securities in the near 
term and may be required to further adjust the carrying 
value  of  these  instruments  through  an  impairment 
charge that may be deemed other-than-temporary.

Impairment of Long-Lived Assets and Investments
We  assess  the  recoverability  of  the  carrying  value  of 
long-lived assets, including finite lived intangible assets, 
whenever  events  or  changes  in  circumstances  indicate 
that the assets may be impaired. We must exercise judg-
ment  in  assessing  whether  an  event  of  impairment  has 
occurred.  For  purposes  of  recognition  and  measure-
ment  of  an  impairment  loss,  long-lived  assets  are 
grouped  with  other  assets  and  liabilities  at  the  lowest 
level  for  which  identifiable  cash  flows  are  largely  inde-
pendent of the cash flows of other assets and liabilities. 
We must exercise judgment in this grouping. If the sum 
of the undiscounted future cash flows expected to result 
from the identified asset group is less than the carrying 
value  of  the  asset  group,  an  impairment  provision  may 
be  required.  The  amount  of  the  impairment  to  be  rec-
ognized is calculated by subtracting the fair value of the 
asset group from the net book value of the asset group. 
Determining future cash flows and estimating fair values 
require significant judgment and are highly susceptible 
to  change  from  period  to  period  because  they  require 
management  to  make  assumptions  about  future  sales 
and cost of sales generally over a long-term period. As a 
result  of  assessments  performed  during  fiscal  2010,  we 
recorded  $0.2  million  in  impairment  expense.  In  fiscal 
2009,  we  recorded  $1.2  million  in  impairment  expense, 
primarily related to the write-off of certain research and 
development  equipment.  See  Note  6  of  the  Notes  to 
the  Consolidated  Financial  Statements  for  more  infor-
mation on this write-off.

We  evaluate  the  estimated  fair  value  of  investments 
annually  or  more  frequently  if  indicators  of  potential 
impairment  exist,  to  determine  if  an  other-than- 
temporary  impairment  in  the  value  of  the  investment 
has taken place.

Business Combinations
We have accounted for all business combinations under 
the  purchase  method  of  accounting.  As  discussed  in  

more detail in Note 2 of the Notes to the Consolidated 
Financial  Statements,  we  were  required  to  adopt  new 
accounting  standards  for  business  combinations  com-
mencing  after  October  1,  2009.  However,  we  have  not 
made  any  acquisitions  to  which  we  were  required  to 
apply  these  new  standards.  We  have  allocated  the  
purchase  price  of  acquired  entities  to  the  tangible  
and intangible assets acquired, liabilities assumed, and 
in-process  research  and  development  (IPR&D)  based  
on their estimated fair values. We engage independent 
third-party  appraisal  firms  to  assist  us  in  determining 
the  fair  values  of  assets  and  liabilities  acquired.  This  
valuation requires management to make significant esti-
mates and assumptions, especially with respect to long-
lived  and  intangible  assets.  Contingent  consideration 
was recorded as a liability when the outcome of the con-
tingency  became  determinable.  Goodwill  represents 
the  excess  of  the  purchase  price  over  the  fair  value  of 
net  assets  and  amounts  assigned  to  identifiable  intan-
gible  assets.  Purchased  IPR&D,  for  which  technological 
feasibility  has  not  yet  been  established  and  no  future 
alternative uses exist, has been expensed immediately.

Critical  estimates  in  valuing  certain  of  the  intangible 
assets  include  but  are  not  limited  to:  future  expected 
cash flows related to acquired developed technologies 
and patents and assumptions about the period of time 
the  technologies  will  continue  to  be  used  in  the  Com-
pany’s product portfolio; expected costs to develop the 
IPR&D into commercially viable products and estimated 
cash flows from the products when completed; and dis-
count rates. Management’s estimates of value are based 
upon assumptions believed to be reasonable, but which 
are inherently uncertain and unpredictable. Assumptions 
may  be  incomplete  or  inaccurate,  and  unanticipated 
events  and  circumstances  may  occur  which  may  cause 
actual  realized  values  to  be  different  from  manage-
ment’s estimates.

Goodwill and Intangible Assets
Purchased  intangible  assets  with  finite  lives  are  amor-
tized over their estimated useful lives and are evaluated 
for  impairment  using  a  process  similar  to  that  used  to 
evaluate other long-lived assets. Goodwill and indefinite 
lived intangible assets are not amortized and are tested 
annually  in  the  fourth  fiscal  quarter  or  more  frequently  
if  indicators  of  potential  impairment  exist,  using  a  fair-
value-based approach.

The recoverability of goodwill is measured at the report-
ing  unit  level,  which  is  defined  as  either  an  operating 
segment  or  one  level  below  an  operating  segment.  A 
component  is  a  reporting  unit  when  the  component 
constitutes a business for which discreet financial infor-
mation is available and segment management regularly 
reviews  the  operating  results  of  the  component.  Com-
ponents may be combined into one reporting unit when  

22

23

they have similar economic characteristics. We had three 
reporting  units  to  which  we  allocated  goodwill  and 
intangible assets as of September 30, 2010, the date of 
our  annual  impairment  test.  Initially,  our  Company  had 
only one reporting unit as we were created from a divi-
sion of our former parent company, Cabot Corporation, 
and  we  identified  associated  goodwill  and  intangible 
assets  under  one  reporting  unit  at  that  time.  Other 
amounts  of  goodwill  and  intangible  assets  have  been 
attributed to acquired businesses at the time of acquisi-
tion through the use of independent appraisal firms.

We  have  consistently  determined  the  fair  value  of  our 
reporting units using a discounted cash flow analysis of 
our projected future results. The recoverability of indefi-
nite lived intangible assets is measured using the royalty 
savings method. Factors requiring significant judgment 
include assumptions related to future growth rates, dis-
count factors, royalty rates and tax rates, among others. 
Changes  in  economic  and  operating  conditions  that 
occur after the annual impairment analysis or an interim 
impairment analysis that impact these assumptions may 
result in future impairment charges.

As a result of the review performed in the fourth quarter 
of fiscal 2010, we determined that there was no impair-
ment  of  our  goodwill  and  intangible  assets  as  of 
September 30, 2010.

Share-Based Compensation
We  record  share-based  compensation  expense  for  all 
share-based  awards,  including  stock  option  grants, 
restricted  stock  and  restricted  stock  unit  awards  and 
employee  stock  purchases.  We  calculate  share-based 
compensation expense using the straight-line approach 
based  on  awards  expected  to  ultimately  vest,  which 
requires  the  use  of  an  estimated  forfeiture  rate.  Our 
estimated forfeiture rate is primarily based on historical 
experience,  but  may  be  revised  in  future  periods  if 
actual  forfeitures  differ  from  the  estimate.  We  use  the 
Black-Scholes  option-pricing  model  to  estimate  the 
grant date fair value of our stock options and employee 
stock purchases. This model requires the input of highly 
subjective  assumptions,  including  the  price  volatility  of 
the  underlying  stock,  the  expected  term  of  our  stock 
options and the risk-free interest rate. A small change in 
the  underlying  assumptions  can  have  a  relatively  large 
effect  on  the  estimated  valuation.  We  estimate  the 
expected volatility of our stock based on a combination 
of our stock’s historical volatility and the implied volatili-
ties  from  actively-traded  options  on  our  stock.  We  cal-
culate the expected term of our stock options using the 
simplified method, due to our limited amount of histori-
cal  option  exercise  data,  and  we  add  a  slight  premium 
to this expected term for employees who meet the defi-
nition  of  retirement  eligible  pursuant  to  terms  of  their  

award  agreements  during  the  contractual  term.  The 
simplified  method  uses  an  average  of  the  vesting  term 
and the contractual term of the option to calculate the 
expected  term.  The  risk-free  rate  is  derived  from  the 
U.S. Treasury yield curve in effect at the time of grant.

The fair value of our restricted stock and restricted stock 
unit awards represents the closing price of our common 
stock on the date of grant.

Accounting for Income Taxes
Current  income  taxes  are  determined  based  on  esti-
mated  taxes  payable  or  refundable  on  tax  returns  for 
the current year. Deferred income taxes are determined 
using enacted tax rates for the effect of temporary dif-
ferences  between  the  book  and  tax  bases  of  recorded 
assets  and  liabilities.  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. 
Provisions  are  made  for  both  U.S.  and  any  foreign 
deferred  income  tax  liability  or  benefit.  We  recognize 
the  tax  benefit  of  an  uncertain  tax  position  only  if  it  is 
more  likely  than  not  that  the  tax  position  will  be  sus-
tained by the taxing authorities, based on the technical 
merits of the position. In fiscal 2010, we elected to per-
manently reinvest the earnings of certain of our foreign 
subsidiaries  outside  the  U.S.  rather  than  repatriating  
the earnings to the U.S. See Note 16 for additional infor-
mation on income taxes.

Commitments and Contingencies
We  have  entered  into  certain  unconditional  purchase 
obligations,  which  include  noncancelable  purchase 
commitments  and  take-or-pay  arrangements  with  sup-
pliers.  We  review  our  agreements  on  a  quarterly  basis 
and make an assessment of the likelihood of a shortfall 
in purchases and determine if it is necessary to record a 
liability. In addition, we are subject to the possibility of 
various loss contingencies arising in the ordinary course 
of business such as a legal proceeding or claim. An esti-
mated  loss  contingency  is  accrued  when  it  is  probable 
that  an  asset  has  been  impaired  or  a  liability  has  been 
incurred and the amount of the loss can be reasonably 
estimated.  We  regularly  evaluate  current  information 
available  to  us  to  determine  whether  such  accruals 
should  be  adjusted  and  whether  new  accruals  are 
required.

Effects of Recent Accounting Pronouncements
See  Note  2  to  the  Consolidated  Financial  Statements  
for a description of recent accounting pronouncements 
including  the  expected  dates  of  adoption  and  effects 
on  our  results  of  operations,  financial  position  and  
cash flows.

Revenue
Revenue  was  $408.2  million  in  fiscal  2010,  which  repre-
sented an increase of 40.1%, or $116.8 million, from fiscal 
2009. The increase in revenue was driven by a $118.3 mil-
lion increase in sales volume, a $4.8 million increase due 
to the effect of foreign exchange rate changes, and $2.6 
million due to a slightly higher-priced product mix, par-
tially offset by a decrease in revenue of $8.9 million due 
to  a  lower  weighted-average  selling  price  for  our  CMP 
consumable products. We began to see improvement in 
economic  and  industry  conditions  during  the  second 
half of our fiscal 2009. These improvements, particularly 
in  the  semiconductor  industry,  continued  through  our 
fiscal 2010 and positively impacted the demand for our 
products.  We  noted  some  positive  signs  of  growth  in 
the  semiconductor  industry  in  the  Overview  section  of 
this  MD&A  including:  reports  from  customers  indicate 
that capacity utilization in fabs is currently at an all-time 
high;  semiconductor  device  inventories  appear  to  be  
at  an  appropriate  level;  and  capacity  expansions  by  a 
number of semiconductor manufacturers are underway. 
How ever, we remain cautious regarding future demand 
trends over the near term as we are entering a calendar 
period  of  typically  lower  seasonal  demand  within  the 
semiconductor  industry  and  we  cannot  predict  the 
exact  timing  and  magnitude  of  a  continued  economic 
recovery.

Cost of Goods Sold
Total cost of goods sold was $204.7 million in fiscal 2010, 
which represented an increase of 25.6%, or $41.8 million, 
from fiscal 2009. The increase in cost of goods sold was 
primarily  due  to  $59.4  million  from  increased  sales  vol-
ume  due  to  the  increased  demand  for  our  products 
associated  with  the  economic  and  industry  recovery, 
and  an  $8.4  million  increase  due  to  higher  fixed  costs. 
These  costs  were  partially  offset  by  a  $16.2  million 
decrease due to higher utilization of our manufacturing 
capacity on the increased sales volume, and a $10.7 mil-
lion benefit of a lower-cost product mix.

Metal oxides, such as silica and alumina, are significant 
raw materials that we use in many of our CMP slurries. In 
an effort to mitigate our risk to rising raw material costs 
and  to  increase  supply  assurance  and  quality  perfor-
mance  requirements,  we  have  entered  into  multi-year 
supply  agreements  with  a  number  of  suppliers.  For 
more  financial  information  about  our  supply  contracts, 
see  “Tabular  Disclosure  of  Contractual  Obligations” 
included in Item 7 of Part II of this Form 10-K.

Our  need  for  additional  quantities  or  different  kinds  of 
key  raw  materials  in  the  future  has  required,  and  will 
continue  to  require,  that  we  enter  into  new  supply 
arrangements  with  third  parties.  Future  arrangements 
may result in costs which are different from those in the 
existing agreements. In addition, energy costs may also 
impact the cost of raw materials, packaging, freight and 
labor costs. We also expect to continue to invest in our 
operations  excellence  initiative  to  improve  product 
quality, reduce variability and improve product yields in 
our manufacturing process.

Gross Profit
Our  gross  profit  as  a  percentage  of  revenue  was  49.9% 
in fiscal 2010 as compared to 44.1% for fiscal 2009. The 
increase in gross profit as a percentage of revenue was 
primarily due to the significant increase in sales volume 
and the related increased utilization of our manufactur-
ing  capacity,  as  well  as  a  higher-valued  product  mix, 
partially  offset  by  a  decrease  in  the  weighted-average 
selling  price  of  our  CMP  slurries  and  increased  fixed 
manufacturing  costs.  We  expect  our  gross  profit  
percentage  for  full  fiscal  year  2011  to  be  in  the  range  
of  48%  to  50%.  However,  we  may  experience  fluctua-
tions  in  our  gross  profit  due  to  a  number  of  factors, 
including the extent to which we utilize our manufactur-
ing capacity and fluctuations in our product mix, which 
may  cause  our  quarterly  gross  profit  to  be  above  or 
below this range.

Research, Development and Technical
Total  research,  development  and  technical  expenses 
were  $51.8  million  in  fiscal  2010,  which  represented  
an  increase  of  7.6%,  or  $3.7  million,  from  fiscal  2009.  
The  increase  was  mainly  due  to  $3.6  million  in  higher  
staffing-related  costs,  primarily  related  to  our  annual 
incentive  bonus  program,  $0.6  million  in  higher  travel-
related  costs,  and  $0.2  million  in  higher  office  equip-
ment  expenses,  partially  offset  by  the  absence  of  $1.1 
million  in  pre-tax  impairment  charges  recorded  on  
certain  research  and  development  equipment  during 
fiscal 2009.

Our  research,  development  and  technical  efforts  are 
focused on the following main areas:

•   Research related to fundamental CMP technology;

•   Development  and  formulation  of  new  and  enhanced 
CMP  consumable  products,  including  collaborating 
on joint development projects with our customers;

•   Process  development  to  support  rapid  and  effective 

commercialization of new products;

•   Technical support of CMP products in our customers’ 

manufacturing facilities; and

•   Evaluation  and  development  of  new  polishing  and 
metrology applications outside of the semiconductor 
industry.

Selling and Marketing
Selling and marketing expenses were $26.9 million in fis-
cal  2010,  which  represented  an  increase  of  20.9%,  or 
$4.6 million, from fiscal 2009. The increase was primarily 
due  to  $2.6  million  in  higher  staffing  related  costs, 
including  costs  associated  with  our  annual  incentive 
bonus  program,  $1.0  million  in  higher  travel-related 
costs,  $0.4  million  in  higher  depreciation  expense,  and 
$0.3 million in higher professional fees.

General and Administrative
General and administrative expenses were $50.8 million 
in  fiscal  2010,  which  represented  an  increase  of  25.0%, 
or  $10.2  million,  from  fiscal  2009.  The  increase  was 
mainly  due  to  $6.0  million  in  higher  staffing-related 
costs,  primarily  related  to  our  annual  incentive  bonus 
program, $4.2 million in higher professional fees, includ-
ing  costs  to  enforce  our  intellectual  property,  and  $0.5 
million in higher travel-related expenses, partially offset 
by $0.9 million due to lower bad debt expense. See Part 
I,  Item  3  entitled  “Legal  Proceedings”  and  Note  17  of 
the  Notes  to  the  Consolidated  Financial  Statements  
for  more  information  on  the  enforcement  of  our  intel-
lectual property.

Purchased In-Process Research  
and Development
Purchased  in-process  research  and  development 
(IPR&D)  expense  was  $1.4  million  in  fiscal  2009,  related 
to the acquisition of Epoch in the second quarter of fis-
cal 2009. We did not make any acquisitions in fiscal 2010.

Other Income (Expense), Net
Other expense was $0.7 million in fiscal 2010, compared 
to  other  income  of  $0.6  million  during  fiscal  2009.  The 
decrease in other income was primarily due to $0.8 mil-
lion in lower interest income resulting from lower inter-
est  rates  on  our  cash  balances  and  investments,  and 
$0.7  million  due  to  net  unfavorable  foreign  exchange 
effects  on  revenues  and  expenses,  primarily  related  to 
changes in the exchange rate of the Japanese yen to the 
U.S.  dollar,  net  of  the  gains  and  losses  incurred  on  for-
ward  foreign  exchange  contracts  discussed  in  Note  10 
of the Notes to the Consolidated Financial Statements.

Provision for Income Taxes
Our  effective  income  tax  rate  was  32.5%  in  fiscal  2010 
compared to 32.7% in fiscal 2009. The decreases in the 
effective tax rate in fiscal 2010 was primarily due to our 
election  to  permanently  reinvest  earnings  from  certain 
of our foreign subsidiaries outside of the U.S., as well as 
decreased  tax  expense  related  to  share-based  com-
pensation.  Increases  in  the  effective  tax  rate  in  fiscal 
2010  that  partially  offset  these  decreases  included 
decreases  in  tax-exempt  interest  income  and  the  pres-
ent  expiration  of  the  research  and  experimentation  tax 
credit effective December 31, 2009. As discussed above 
in  the  Overview  section  of  this  MD&A,  our  election  to 
permanently  reinvest  earnings  of  certain  of  our  foreign 
subsidiaries  outside  the  U.S.  reduced  our  effective  tax 
rate in fiscal 2010 by 2.7 percentage points.

Net Income
Net income was $49.5 million in fiscal 2010, which repre-
sented an increase of 342.1%, or $38.3 million, from fiscal 
2009  as  a  result  of  the  factors  discussed  above.  The 
election to permanently reinvest the earnings of certain 
of  our  foreign  subsidiaries  outside  the  U.S.  increased 
net income by $2.0 million in fiscal 2010.

Year Ended September 30, 2009, Versus Year 
Ended September 30, 2008

Revenue
Revenue  was  $291.4  million  in  fiscal  2009,  which  repre-
sented a decrease of 22.3%, or $83.7 million, from fis-
cal  2008.  Of  this  decrease,  $97.7  million  was  due  to  

26

27

decreased sales volume driven by the significant weak-
ening  of  demand  for  our  products  due  to  the  global 
economic recession that we experienced during the first 
half of fiscal 2009, and $8.5 million due to product mix. 
These  decreases  in  revenue  were  partially  offset  by 
$13.0 million in revenue from Epoch products, a $5.7 mil-
lion  revenue  increase  due  to  the  effect  of  foreign 
exchange rate changes and $3.8 million due to a higher 
weighted-average selling price for our CMP consumable 
products.  Despite  the  negative  effects  of  the  global 
economic recession on our slurry products for semicon-
ductor applications and on our ESF business, our reve-
nue  from  CMP  polishing  pads  and  slurries  for  data 
storage  applications  increased  from  the  prior  year.  We 
believe a combination of improved underlying demand 
and  inventory  replenishment  within  the  semiconductor 
industry  positively  impacted  demand  for  our  products 
during  the  second  half  of  fiscal  2009  as  our  revenues 
improved  significantly  from  the  revenues  recorded  in 
the first half of the fiscal year.

Cost of Goods Sold
Total cost of goods sold was $162.9 million in fiscal 2009, 
which represented a decrease of 18.8%, or $37.7 million, 
from fiscal 2008. The decrease in cost of goods sold was 
primarily due to $53.2 million from decreased sales vol-
ume due to the global economic recession, $9.8 million 
from  lower  fixed  manufacturing  costs  and  $5.9  million 
due  to  higher  manufacturing  yields  in  our  CMP  slurry 
and pad production. These decreases were partially off-
set by a $16.0 million increase due to a higher-cost prod-
uct mix, a $9.2 million increase due to lower utilization of 
our  manufacturing  capacity  on  the  decreased  level  of 
sales, a $4.6 million increase due to the effect of foreign 
exchange  rate  changes  and  a  $2.0  million  increase  in 
certain other manufacturing variances. We implemented 
a number of cost saving initiatives during the first half of 
fiscal 2009. For example, we shortened work schedules 
in  our  manufacturing  operations  on  a  global  basis  to 
more  closely  match  production  with  demand,  but  we 
maintained the flexibility to increase our production lev-
els  to  meet  the  increased  customer  demand  for  our 
products that we experienced during the second half of 
fiscal 2009.

Gross Profit
Our  gross  profit  as  a  percentage  of  revenue  was  44.1% 
in fiscal 2009 as compared to 46.5% for fiscal 2008. The 
decrease  in  gross  profit  expressed  as  a  percentage  of 
revenue was primarily due to the underutilization of our 
manufacturing  capacity  on  the  significantly  lower  level 
of  sales  and  a  higher-cost  product  mix,  partially  offset 
by  lower  fixed  manufacturing  costs  and  favorable  pro-
duction yields.

Research, Development and Technical
Total  research,  development  and  technical  expenses 
were  $48.2  million  in  fiscal  2009,  which  represented  a 
decrease  of  2.0%,  or  $1.0  million,  from  fiscal  2008.  The 
decrease  was  primarily  related  to  $1.7  million  in  lower 
staffing-related costs, $0.7 million in lower depreciation 
expense  and  $0.4  million  in  lower  travel-related  costs. 
These  cost  decreases  were  partially  offset  by  $1.2  mil-
lion  in  pre-tax  impairments  recorded  in  fiscal  2009  on 
certain research and development equipment and $0.4 
million in higher expenses for laboratory supplies.

Selling and Marketing
Selling  and  marketing  expenses  were  $22.2  million  in  
fiscal  2009,  which  represented  a  decrease  of  21.4%,  or 
$6.0 million, from fiscal 2008. The decrease was primar-
ily due to $3.9 million in lower staffing related costs, $1.0 
million in lower travel-related costs, $0.3 million in lower 
advertising  and  trade  show  costs  and  $0.3  million  in 
lower professional fees.

General and Administrative
General and administrative expenses were $40.6 million 
in  fiscal  2009,  which  represented  a  decrease  of  14.6%,  
or  $7.0  million,  from  fiscal  2008.  The  decrease  resulted 
primarily from $4.0 million in lower staffing-related costs, 
primarily related to our annual incentive bonus program 
and  lower  share-based  compensation  expense,  and  
$3.7  million  in  lower  professional  fees,  including  costs  
to enforce our intellectual property. These cost savings 
were  partially  offset  by  a  $0.9  million  increase  in  our 
allowance  for  doubtful  accounts  due  to  customer  
bankruptcies  and  increased  risks  relating  to  customer 
collections  due  to  the  continued  uncertainty  in  the 
global economy.

Purchased In-Process Research  
and Development
Purchased in-process research and development (IPR&D) 
expense  was  $1.4  million  in  fiscal  2009,  related  to  the 
acquisition of Epoch in the second quarter of fiscal 2009. 
We did not make any acquisitions in fiscal 2008.

Other Income, Net
Other income was $0.6 million in fiscal 2009, which rep-
resented a decrease of 89.0%, or $4.9 million, from fiscal 
2008.  The  decrease  in  other  income  was  primarily  due 
to  $4.5  million  in  lower  interest  income  resulting  from 
lower  interest  rates  on  our  lower  average  balances  of 
cash  and  short-term  investments.  We  monetized  the 
majority of our short-term investments in ARS during fis-
cal 2008 and reinvested these funds into money market 
investments which earn interest at lower rates.

Provision for Income Taxes
Our  effective  income  tax  rate  was  32.7%  in  fiscal  2009 
compared  to  30.2%  in  fiscal  2008.  The  increase  in  the 
effective  tax  rate  in  fiscal  2009  was  primarily  due  to 
increased tax expense related to share-based compen-
sation  and  a  decrease  in  tax-exempt  interest  income, 
partially offset by increased research and experimenta-
tion tax credits.

Net Income
Net income was $11.2 million in fiscal 2009, which repre-
sented a decrease of 70.8%, or $27.2 million, from fiscal 
2008 as a result of the factors discussed above. The acqui-
sition of Epoch was accretive to earnings in fiscal 2009.

Liquidity and Capital Resources
We had cash flows from operating activities of $88.4 mil-
lion in fiscal 2010, $44.7 million in fiscal 2009 and $70.8 
million  in  fiscal  2008.  Our  cash  provided  by  operating 
activities  in  fiscal  2010  originated  from  $49.5  million  in 
net income, $34.2 million in non-cash items, and a $4.7 
million  increase  in  cash  flow  due  to  a  net  decrease  in 
working  capital.  The  increase  in  cash  from  operations  
in  fiscal  2010  from  fiscal  2009  was  primarily  due  to 
increased net income in fiscal 2010 due to the improved 
economic  and  industry  conditions  and  the  timing  
of  accounts  payable  and  accrued  liability  payments, 
including the accrual of our annual incentive bonus pro-
gram  expenses  related  to  fiscal  2010.  These  were  par-
tially offset by increases in fiscal 2010 in our other current 
assets,  primarily  due  to  income  taxes  receivable,  and 
our inventory levels based on the increased demand for 
our products.

We used $11.9 million in investing activities in fiscal 2010 
representing  $11.7  million  in  purchases  of  property, 
plant and equipment and $0.2 million in other investing 
cash outflows. We used $69.0 million in investing activi-
ties  in  fiscal  2009,  representing  $60.5  million  used  for 
our  acquisition  of  Epoch,  net  of  $6.2  million  in  cash 
acquired,  and  $8.5  million  in  purchases  of  property, 
plant and equipment. Cash flows provided by investing 
activities in fiscal 2008 were $130.3 million. Net sales of 
short-term investments were $149.5 million as we mone-
tized the majority of our ARS during fiscal 2008 (as dis-
cussed  below).  This  cash  inflow  was  partially  offset  by 
$19.2  million  in  cash  used  for  purchases  of  property, 
plant  and  equipment  primarily  for  the  purchase  and 
installation of a 300-millimeter polishing tool and related 
metrology  equipment  for  our  Asia  Pacific  technology 
center  and  building  improvements  and  equipment  to 
increase  our  pad  production  capabilities.  See  Note  3 
and  Note  7  of  the  Notes  to  the  Consolidated  Financial 
Statements for more information on business combina-
tions  and  intangible  assets.  We  estimate  that  our  total 
capital expenditures in fiscal 2011 will be approximately 
$25.0 million.

In fiscal 2010, cash flows used in financing activities were 
$23.5 million. We used $25.0 million to repurchase com-
mon stock under our share repurchase plan, $0.8 million 
to  repurchase  common  stock  pursuant  to  the  terms  of 
our  Second  Amended  and  Restated  Cabot  Microelec-
tronics Corporation 2000 Equity Incentive Plan (EIP) for 
shares  withheld  from  employees  and  purchased  by  
the  Company  to  cover  payroll  taxes  on  the  vesting  of 
restricted  stock  granted  under  the  EIP,  and  we  made 
$1.2  million  in  principal  payments  under  capital  lease 
obligations.  These  cash  outflows  were  partially  offset  
by  $3.4  million  received  from  the  issuance  of  common 
stock  related  to  the  exercise  of  stock  options  granted 
under  our  EIP  and  our  2007  Employee  Stock  Purchase 
Plan,  as  amended  and  restated  January  1,  2010  (2007 
Employee Stock Purchase Plan). In fiscal 2009, cash flows 
provided  by  financing  activities  were  $0.7  million.  We 
received $2.2 million from the issuance of common stock 
related  to  the  exercise  of  stock  options  granted  under 
our  EIP  and  our  2007  Employee  Stock  Purchase  Plan. 
These cash inflows were partially offset by $1.1 million in 
principal payments on capital leases and $0.3 million in 
repurchases of common stock pursuant to the terms of 
our  EIP  for  shares  withheld  to  cover  payroll  taxes  on  
the  vesting  of  restricted  stock  granted  under  the  EIP.  
In  fiscal  2008,  cash  flows  used  in  financing  activities 
were $35.2 million. We used $39.0 million to repurchase 
common  stock  under  our  share  repurchase  programs 
and  we  made  $1.1  million  in  principal  payments  under 
capital lease obligations. These cash outflows were par-
tially offset by $4.9 million received from the issuance of 
common  stock  related  to  the  exercise  of  stock  options 
and  shares  issued  under  our  2007  Employee  Stock 
Purchase Plan.

In  January  2008,  the  Board  of  Directors  authorized  a 
share repurchase program for up to $75.0 million of our 
outstanding  common  stock.  Shares  are  repurchased 
from  time  to  time,  depending  on  market  conditions,  in 
open  market  transactions,  at  management’s  discretion. 
We  fund  share  repurchases  from  our  existing  cash  bal-
ance.  The  program  became  effective  on  the  authori-
zation  date  and  may  be  suspended  or  terminated  at  
any time, at the Company’s discretion. There was $25.0 
million remaining on this authorization as of September 
30, 2010.

We  have  an  unsecured  revolving  credit  facility  of  $50.0 
million  with  an  option  to  increase  the  facility  to  $80.0 
million.  Pursuant  to  an  amendment  we  entered  into  in 
October  2008,  the  agreement  extends  to  November 
2011,  with  an  option  to  renew  for  two  additional  one-
year  terms.  In  November  2010,  the  scheduled  termina-
tion  date  was  extended  by  one  year  through  October 
2012.  The  amendment  did  not  include  any  other  mate-
rial changes to the terms of the credit agreement. Under 
this  agreement,  interest  accrues  on  any  outstanding 

28

29

balance  at  either  the  lending  institution’s  base  rate  or 
the  Eurodollar  rate  plus  an  applicable  margin.  We  also 
pay a non-use fee. Loans under this facility are intended 
primarily  for  general  corporate  purposes,  including 
financing  working  capital,  capital  expenditures  and 
acquisitions. The credit agreement also contains various 
covenants. No amounts are currently outstanding under 
this  credit  facility  and  we  believe  we  are  currently  in 
compliance with the covenants.

As discussed in Note 3 of the Notes to the Consolidated 
Financial  Statements,  we  completed  the  acquisition  of 
Epoch  during  our  second  quarter  of  fiscal  2009.  The 
total  cash  outlay  was  $60.5  million  representing  $59.4 
million in cash paid to Epoch’s shareholders on the first 
closing  date  of  February  27,  2009,  $0.7  million  in  cash 
paid for transaction costs and $6.6 million paid to Eternal 
on  the  second  closing  date  in  August  2010,  which  had 
been in escrow in Taiwan, partially offset by $6.2 million 
in cash acquired with Epoch.

At September 30, 2010, we owned two ARS with an esti-
mated  fair  value  of  $8.1  million  ($8.3  million  par  value). 
We  successfully  monetized  at  par  value  the  majority  of 
ARS we owned in fiscal 2008 and reinvested these funds 
in  money  market  accounts.  We  believe  that  we  will  be 
able  to  monetize  the  remaining  two  ARS  at  par,  either 
through successful auctions, refinancing of the underly-
ing debt by the issuers, payment by the bond insurance 
carrier,  or  holding  the  securities  to  maturity.  However, 
we believe it is not likely that our ARS will be monetized 
within the next operating cycle, which for us is generally 
one year, so we have classified these securities as long-
term assets.

We  believe  that  our  current  balance  of  cash  and  long-
term  investments,  cash  generated  by  our  operations 
and  available  borrowings  under  our  revolving  credit 
facility will be sufficient to fund our operations, expected 
capital  expenditures,  merger  and  acquisition  activities, 
and  share  repurchases  for  the  foreseeable  future. 
However, we plan to further expand our business; there-
fore, we may need to raise additional funds in the future 
through equity or debt financing, strategic relationships 
or  other  arrangements.  Depending  upon  future  condi-
tions in the capital and credit markets, we could encoun-
ter difficulty securing additional financing in the type or 
amount necessary to pursue these objectives.

Off-Balance Sheet Arrangements
At  September  30,  2010  and  2009,  we  did  not  have  any 
unconsolidated  entities  or  financial  partnerships,  such 
as  entities  often  referred  to  as  structured  finance  or  
special purpose entities, which might have been estab-
lished  for  the  purpose  of  facilitating  off-balance  sheet 
arrangements.

Capital Lease Obligations
In  December  2001,  we  entered  into  a  fumed  alumina 
supply  agreement  with  Cabot  Corporation,  our  former 
parent  company  which  is  not  a  related  party,  under 
which  we  agreed  to  pay  Cabot  Corporation  for  the 
expansion  of  a  fumed  alumina  manufacturing  facility  in 
Tuscola, Illinois. The arrangement for the facility has been 
treated  as  a  capital  lease  for  accounting  purposes  and 
the  present  value  of  the  minimum  quarterly  payments 
resulted  in  an  initial  $9.8  million  lease  obligation  and 
related  leased  asset.  The  initial  term  of  the  agreement 
expired  in  December  2006,  but  it  was  renewed  for 
another five-year term ending in December 2011.

Operating Leases
We lease certain vehicles, warehouse facilities, office 
space, machinery and equipment under cancelable and 
noncancelable  operating  leases,  most  of  which  expire 
within  ten  years  of  their  respective  commencement 
dates and may be renewed by us. Operating lease obli-
gations  also  include  certain  costs  associated  with  our 
pad finishing operation located at Taiwan Semiconductor 
Manufacturing  Company,  which  are  accounted  for  as 
operating lease payments.

Purchase Obligations
We have entered into multi-year supply agreements with 
Cabot  Corporation  for  the  purchase  of  certain  fumed 
metal oxides. We purchase fumed silica primarily under 
a fumed silica supply agreement with Cabot Corporation 
that  became  effective  in  January  2004,  and  was 
amended in September 2006 and in April 2008, the lat-
ter of which extended the termination date of the agree-
ment from December 2009 to December 2012 and also 
changed the pricing and some other non-material terms 
of  the  agreement  to  the  benefit  of  both  parties.  The 
agreement  will  automatically  renew  unless  either  party 
gives  certain  notice  of  non-renewal.  We  are  generally  

28

29

obligated  to  purchase  fumed  silica  for  at  least  90%  of 
our  six-month  volume  forecast  for  certain  of  our  slurry 
products,  to  purchase  certain  non-material  minimum 
quantities every six months, and to pay for the shortfall 
if  we  purchase  less  than  these  amounts.  We  currently 
anticipate  meeting  all  minimum  forecasted  purchase 
volume  requirements.  Since  December  2001,  we  have 
purchased fumed alumina primarily under a fumed alu-
mina  supply  agreement  with  Cabot  Corporation  that 
has an original term ending in December 2006 and was 
renewed for another five-year term ending in December 
2011.  Prices  charged  for  fumed  alumina  from  Cabot 
Corporation  are  pursuant  to  the  terms  of  the  supply 
agreement  and  may  fluctuate  based  upon  the  actual 
costs incurred by Cabot Corporation in the manufacture 
of  fumed  alumina.  Under  these  agreements,  Cabot 
Corporation  continues  to  be  the  exclusive  supplier  of 
certain  quantities  and  types  of  fumed  silica  and  fumed 
alumina  for  certain  products  we  produced  as  of  the 
effective dates of these agreements. Subject to certain 
terms, Cabot Corporation is prohibited from selling cer-
tain  types  of  fumed  alumina  to  third  parties  for  use  in 
CMP  applications,  as  well  as  engaging  itself  in  CMP 
applications. If Cabot Corporation fails to supply us with 
our requirements for any reason, including if we require 
product  specification  changes  that  Cabot  Corporation 
cannot  meet,  we  have  the  right  to  purchase  products 
meeting  those  specifications  from  other  suppliers.  We 
also may purchase fumed alumina and fumed silica from 
other  suppliers  for  certain  products,  including  those 
commercialized  after  certain  dates  related  to  these 
agreements  and  their  amendments.  Purchase  obliga-
tions  include  an  aggregate  amount  of  $7.4  million  of 
contractual  commitments  related  to  our  Cabot  Corpo-
ration agreements for fumed silica and fumed alumina.

Other Long-Term Liabilities
Other long-term liabilities at September 30, 2010 consist 
of  liabilities  related  to  our  Japan  retirement  allowance 
and our liability for uncertain tax positions.

Item 7A.  Quantitative and Qualitative 

Disclosures About Market Risk

Effect of Currency Exchange Rates and 
Exchange Rate Risk Management
We  conduct  business  operations  outside  of  the  United 
States through our foreign operations. Some of our for-
eign  operations  maintain  their  accounting  records  in 
their  local  currencies.  Consequently,  period  to  period 
comparability  of  results  of  operations  is  affected  by  
fluctuations  in  exchange  rates.  The  primary  currencies  

to  which  we  have  exposure  are  the  Japanese  yen  and 
the New Taiwan dollar and, to a lesser extent, the British 
pound  and  the  euro.  From  time  to  time  we  enter  into 
forward contracts in an effort to manage foreign currency 
exchange  exposure.  However,  we  may  be  unable  to 
hedge  these  exposures  completely.  During  fiscal  2010, 
we recorded $4.6 million in foreign currency translation 
gains that are included in other comprehensive income 
on our Consolidated Balance Sheet. These gains primar-
ily  relate  to  general  fluctuations  of  the  U.S.  dollar  rela-
tive  to  the  Japanese  yen.  Approximately  18%  of  our 
revenue  is  transacted  in  currencies  other  than  the  U.S. 
dollar. However, we also incur expenses in foreign coun-
tries that are transacted in currencies other than the U.S. 
dollar,  so  the  net  exposure  on  the  Consolidated 
Statement  of  Income  is  limited.  We  do  not  currently 
enter  into  forward  exchange  contracts  or  other  deriva-
tive instruments for speculative or trading purposes.

Market Risk and Sensitivity Analysis Related to 
Foreign Exchange Rate Risk
We  have  performed  a  sensitivity  analysis  assuming  a 
hypothetical  10%  adverse  movement  in  foreign 
exchange rates. As of September 30, 2010, the analysis 
demonstrated  that  such  market  movements  would  
not have a material adverse effect on our consolidated 
financial  position,  results  of  operations  or  cash  flows 
over  a  one-year  period.  Actual  gains  and  losses  in  the 
future  may  differ  materially  from  this  analysis  based  on 
changes  in  the  timing  and  amount  of  foreign  currency 
rate movements and our actual exposures.

Market Risk Related to Investments in Auction 
Rate Securities
At  September  30,  2010,  we  owned  two  auction  rate 
securities  (ARS) with  a total  estimated  fair  value  of  $8.1 
million  ($8.3  million  par  value)  which  were  classified  as 
other  long-term  assets  on  our  Consolidated  Balance 
Sheet.  Beginning  in  2008,  general  uncertainties  in  the 
global  credit  markets  caused  widespread  ARS  auction 
failures  as  the  number  of  securities  submitted  for  sale 
exceeded  the  number  of  securities  buyers  were  willing 
to  purchase.  As  a  result,  the  short-term  liquidity  of  the 
ARS  market  has  been  adversely  affected.  For  more 
information  on  our  ARS,  see  “Risk  Factors”  set  forth  in 
Part  I,  Item  1A,  “Critical  Accounting  Policies  and 
Estimates” in Management’s Discussion and Analysis of 
Financial Condition and Results of Operations in Part II, 
Item  7,  and  Notes  4  and  8  of  the  Notes  to  the 
Consolidated  Financial  Statements  in  Part  II,  Item  8  of 
this Annual Report on Form 10-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of  
Cabot Microelectronics Corporation:

In our opinion, the consolidated financial statements 
listed  in  the  accompanying  index  present  fairly,  in  
all  material  respects,  the  financial  position  of  Cabot 
Microelectronics  Corporation  and  its  subsidiaries  at 
September  30,  2010  and  2009,  and  the  results  of  their 
operations  and  their  cash  flows  for  each  of  the  three 
years in the period ended September 30, 2010 in confor-
mity  with  accounting  principles  generally  accepted  in 
the United States of America. In addition, in our opinion, 
the financial statement schedule listed in the accompa-
nying  index  presents  fairly,  in  all  material  respects,  the 
information  set  forth  therein  when  read  in  conjunction 
with the related consolidated financial statements. Also 
in our opinion, the Company maintained, in all material 
respects, effective internal control over financial report-
ing  as  of  September  30,  2010,  based  on  criteria  estab-
lished in Internal Control—Integrated Framework issued 
by  the  Committee  of  Sponsoring  Organizations  of  the 
Treadway  Commission  (COSO).  The  Company’s  man-
agement  is  responsible  for  these  financial  statements 
and financial statement schedule, for maintaining effec-
tive  internal  control  over  financial  reporting  and  for  its 
assessment of the effectiveness of internal control over 
financial  reporting,  included  in  Management’s  Report 
on Internal Control Over Financial Reporting appearing 
under Item 9A. Our responsibility is to express opinions 
on these financial statements, on the financial statement 
schedule,  and  on  the  Company’s  internal  control  over 
financial  reporting  based  on  our  integrated  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 audits to obtain reasonable assurance 
about whether the financial statements are free of mate-
rial misstatement and whether effective internal control 
over  financial  reporting  was  maintained  in  all  material 
respects. Our audits of the financial statements included 
examining,  on  a  test  basis,  evidence  supporting  the 
amounts  and  disclosures  in  the  financial  statements, 
assessing the accounting principles used and significant 
estimates  made  by  management,  and  evaluating  the 
overall  financial  statement  presentation.  Our  audit  of 
internal control over financial reporting included obtain-
ing  an  understanding  of  internal  control  over  financial  

reporting,  assessing  the  risk  that  a  material  weakness 
exists, and testing and evaluating the design and oper-
ating  effectiveness  of  internal  control  based  on  the 
assessed risk. Our audits also included performing such 
other procedures as we considered necessary in the cir-
cumstances.  We  believe  that  our  audits  provide  a  rea-
sonable basis for our opinions.

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  pur-
poses  in  accordance  with  generally  accepted  account-
ing principles. A company’s internal control over financial 
reporting  includes  those  policies  and  procedures  that  
(i) pertain to the maintenance of records that, in reason-
able detail, accurately and fairly reflect the transactions 
and  dispositions  of  the  assets  of  the  company;  (ii)  pro-
vide reasonable assurance that transactions are recorded 
as  necessary  to  permit  preparation  of  financial  state-
ments  in  accordance  with  generally  accepted  account-
ing  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 (iii) provide reasonable assurance regard-
ing  prevention  or  timely  detection  of  unauthorized 
acquisition, use, or disposition of the company’s assets 
that  could  have  a  material  ef fec t  on  the  financial 
statements.

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(In thousands, except share and per share amounts)

1. Background and Basis of Presentation
Cabot Microelectronics Corporation (“Cabot Microelec-
tronics”,  “the  Company”,  “us”,  “we”,  or  “our”)  supplies 
high-performance  polishing  slurries  used  in  the  manu-
facture of advanced integrated circuit (IC) devices within 
the  semiconductor  industry,  in  a  process  called  chemi-
cal  mechanical  planarization  (CMP).  CMP  polishes  sur-
faces  at  an  atomic  level,  thereby  enabling  IC  device 
manufacturers to produce smaller, faster and more com-
plex  IC  devices  with  fewer  defects.  We  believe  we  are 
the  world’s  leading  supplier  of  CMP  slurries  for  IC 
devices.  We  also  develop,  manufacture  and  sell  CMP 
slurries  for  polishing  certain  components  in  hard  disk 
drives,  specifically  rigid  disk  substrates  and  magnetic 
heads, and we believe we are one of the leading suppli-
ers  in  this  area.  In  addition,  we  develop,  produce  and 
sell CMP polishing pads, which are used in conjunction 
with  slurries  in  the  CMP  process.  We  also  continue  to 
pursue  other  demanding  surface  modification  applica-
tions  through  our  Engineered  Surface  Finishes  (ESF) 
business  for  which  we  believe  we  can  leverage  our 
expertise  in  CMP  consumables  for  the  semiconductor 
industry  to  develop  products  for  demanding  polishing 
applications in other industries.

The  audited  consolidated  financial  statements  have 
been prepared by us pursuant to the rules of the Secu-
rities  and  Exchange  Commission  (SEC)  and  accounting 
principles  generally  accepted  in  the  United  States  of 
America.  We  operate  predominantly  in  one  industry 
segment—the  development,  manufacture,  and  sale  of 
CMP consumables.

2. Summary of Significant Accounting Policies

Principles of Consolidation
The  consolidated  financial  statements  include  the 
accounts of Cabot Microelectronics and its subsidiaries. 
All  intercompany  transactions  and  balances  between 
the  companies  have  been  eliminated  as  of  September 
30, 2010.

Use of Estimates
The  preparation  of  financial  statements  and  related  
disclosures  in  conformity  with  accounting  principles 
generally  accepted  in  the  United  States  of  America 
requires management to make judgments, assumptions 
and  estimates  that  affect  the  amounts  reported  in  the 
consolidated  financial  statements  and  accompanying 
notes.  The  accounting  estimates  that  require  manage-
ment’s most difficult and subjective judgments include, 
but  are  not  limited  to,  those  estimates  related  to  bad  

debt expense, warranty obligations, inventory valuation, 
valuation  and  classification  of  auction  rate  securities, 
impairment  of  long-lived  assets  and  investments,  busi-
ness combinations, goodwill, other intangible assets, share-
based  compensation,  income  taxes  and  contingencies. 
We base our estimates on historical experience, current 
conditions  and  on  various  other  assumptions  that  we 
believe  are  reasonable  under  the  circumstances.  How-
ever, future events are subject to change and estimates 
and  judgments  routinely  require  adjustment.  Actual 
results  may  differ  from  these  estimates  under  different 
assumptions or conditions.

Cash, Cash Equivalents and Short-Term Investments
We  consider  investments  in  all  highly  liquid  financial 
instruments  with  original  maturities  of  three  months  
or  less  to  be  cash  equivalents.  Short-term  investments 
include securities generally having maturities of 90 days 
to  one  year.  We  did  not  own  any  securities  that  were 
considered  short-term  as  of  September  30,  2010  or 
2009. See Note 4 for a more detailed discussion of other 
financial instruments.

Accounts Receivable and Allowance for  
Doubtful Accounts
Trade accounts receivable are recorded at the invoiced 
amount and do not bear interest. We maintain an allow-
ance  for  doubtful  accounts  for  estimated  losses  result-
ing from the potential inability of our customers to make 
required payments. Our allowance for doubtful accounts 
is based on historical collection experience, adjusted for 
any specific known conditions or circumstances such as 
customer  bankruptcies  and  increased  risk  due  to  eco-
nomic  conditions.  Uncollectible  account  balances  are 
charged against the allowance when we believe that it is 
probable that the receivable will not be recovered. See 
Schedule II under Part IV, Item 15 of this Form 10-K for 
more information on our allowance for doubtful accounts.

Concentration of Credit Risk
Financial  instruments  that  subject  us  to  concentrations 
of  credit  risk  consist  principally  of  accounts  receivable. 
We  perform  ongoing  credit  evaluations  of  our  custom-
ers’  financial  conditions  and  generally  do  not  require 
collateral  to  secure  accounts  receivable.  Our  exposure 
to  credit  risk  associated  with  nonpayment  is  affected 
principally by conditions or occurrences within the semi-
conductor industry and global economy. We historically 
have  not  experienced  material  losses  relating  to 
accounts receivable from individual customers or groups 
of customers.

TSMC  accounted  for  13.6%  and  14.0%  of  net  accounts 
receivable  at  September  30,  2010  and  2009,  respec-
tively.  UMC  accounted  for  9.2%  of  net  accounts  receiv-
able at September 30, 2010.

Fair Values of Financial Instruments
The recorded amounts of cash, accounts receivable, and 
accounts  payable  approximate  their  fair  values  due  to 
their  short-term,  highly  liquid  characteristics.  The  fair 
value  of  our  long-term  auction  rate  securities  (ARS)  is 
determined through discounted cash flow analyses. See 
Note 4 for a more detailed discussion of the fair value of 
financial instruments.

Inventories
Inventories  are  stated  at  the  lower  of  cost,  determined 
on the first-in, first-out (FIFO) basis, or market. Finished 
goods and work in process inventories include material, 
labor  and  manufacturing  overhead  costs.  We  regularly 
review and write down the value of inventory as required 
for estimated obsolescence or unmarketability. An inven-
tory  reserve  is  maintained  based  upon  a  historical  per-
centage of actual inventories written off applied against 
inventory  value  at  the  end  of  the  period,  adjusted  for 
known conditions and circumstances.

Property, Plant and Equipment
Property,  plant  and  equipment  are  recorded  at  cost. 
Depreciation is based on the following estimated useful 
lives of the assets using the straight-line method:

Buildings
Machinery and equipment
Furniture and fixtures
Information systems

Assets under capital leases

15–25 years
  3–10 years
  5–10 years
  3–5 years
Term of lease or  
  estimated useful life

Expenditures  for  repairs  and  maintenance  are  charged 
to expense as incurred. Expenditures for major renewals 
and  betterments  are  capitalized  and  depreciated  over 
the remaining useful lives. As assets are retired or sold, 
the  related  cost  and  accumulated  depreciation  are 
removed  from  the  accounts  and  any  resulting  gain  or 
loss  is  included  in  the  results  of  operations.  Costs 
related  to  the  design  and  development  of  internal  use 
software are capitalized.

Impairment of Long-Lived Assets
Reviews  are  regularly  performed  to  determine  whether 
facts and circumstances exist that indicate the carrying 
amount of assets may not be recoverable or the useful 
life  is  shorter  than  originally  estimated.  Asset  recover-
ability  assessment  begins  by  comparing  the  projected 
undiscounted  cash  flows  associated  with  the  related 
asset  or  group  of  assets  over  their  remaining  lives 
against  their  respective  carrying  amounts.  Impairment, 
if  any,  is  based  on  the  excess  of  the  carrying  amount 
over  the  fair  value  of  those  assets.  If  assets  are  deter-
mined  to  be  recoverable,  but  their  useful  lives  are 
shorter than originally estimated, the net book value of 
the  asset  is  depreciated  over  the  newly  determined 
remaining useful life.

Goodwill and Intangible Assets
We amortize intangible assets with finite lives over their 
estimated useful lives, which range from two to ten and 
one-half  years.  Intangible  assets  with  finite  lives  are 
reviewed for impairment using a process similar to that 
used  to  evaluate  other  long-lived  assets.  Goodwill  and 
indefinite lived intangible assets are not amortized and 
are  tested  annually  in  the  fourth  fiscal  quarter  or  more 
frequently  if  indicators  of  potential  impairment  exist, 
using a fair-value-based approach. The recoverability of 
goodwill is measured at the reporting unit level, which is 
defined  as  either  an  operating  segment  or  one  level 
below  an  operating  segment,  referred  to  as  a  compo-
nent. A component is a reporting unit when the compo-
nent  constitutes  a  business  for  which  discreet  financial 
information is available and segment management reg-
ularly  reviews  the  operating  results  of  the  component. 
Components may be combined into one reporting unit 
when  they  have  similar  economic  characteristics.  We 
had  three  reporting  units  to  which  we  allocated  good-
will  and  intangible  assets  as  of  September  30,  2010. 
Goodwill  impairment  testing  requires  a  comparison  of 
the fair value of each reporting unit to the carrying value. 
If the carrying value exceeds fair value, goodwill is con-
sidered impaired. The amount of the impairment is the 
difference  between  the  carrying  value  of  goodwill  and 
the “implied” fair value. The fair value of the reporting 
unit is determined using a discounted cash flow analysis 
of  our  projected  future  results.  The  recoverability  of 
indefinite  lived  intangible  assets  is  measured  using  the 
royalty  savings  method,  which  requires  a  comparison 
between the fair value of the discounted royalty savings 
and  the  carrying  value  of  the  assets.  We  determined 
that  goodwill  and  other  intangible  assets  were  not 
impaired as of September 30, 2010.

38

39

Warranty Reserve
We  maintain  a  warranty  reserve  that  reflects  manage-
ment’s best estimate of the cost to replace product that 
does  not  meet  customers’  specifications  and  perfor-
mance  requirements.  The  warranty  reserve  is  based 
upon  a  historical  product  return  rate,  adjusted  for  any 
specific  known  conditions  or  circumstances.  Adjust-
ments  to  the  warranty  reserve  are  recorded  in  cost  of 
goods sold.

Foreign Currency Translation
Certain  operating  activities  in  Asia  and  Europe  are 
denominated  in  local  currency,  considered  to  be  the 
functional currency. Assets and liabilities of these oper-
ations  are  translated  using  exchange  rates  in  effect  at 
the  end  of  the  year,  and  revenue  and  costs  are  trans-
lated  using  weighted-average  exchange  rates  for  the 
year. The related translation adjustments are reported in 
comprehensive income in stockholders’ equity.

Foreign Exchange Management
We  transact  business  in  various  foreign  currencies,  pri-
marily  the  Japanese  yen,  New  Taiwan  dollar,  British 
pound and the euro. Our exposure  to  foreign currency 
exchange risks has not been significant because a large 
portion  of  our  business  is  denominated  in  U.S.  dollars. 
Periodically  we  enter  into  forward  foreign  exchange 
contracts  in  an  effort  to  mitigate  the  risks  associated 
with  currency  fluctuations  on  certain  foreign  currency 
balance  sheet  exposures.  Our  foreign  exchange  con-
tracts  do  not  qualify  for  hedge  accounting  under  the 
accounting rules for derivative instruments. See Note 10 
for more a more detailed discussion of derivative finan-
cial instruments.

Intercompany Loan Accounting
We  maintain  intercompany  loan  agreements  with  our 
wholly-owned subsidiary, Nihon Cabot Microelectronics 
K.K. (“the K.K.”), under which we provided funds to the 
K.K.  to  finance  the  purchase  of  certain  assets  from  our 
former Japanese branch at the time of the establishment 
of  this  subsidiary,  for  the  purchase  of  land  adjacent  to 
our  Geino,  Japan,  facility,  for  the  construction  of  our 
Asia Pacific technology center, and for the purchase of a 
300  millimeter  polishing  tool  and  related  metrology 
equipment,  all  of  which  are  part  of  the  K.K.,  as  well  as  
for  general  business  purposes.  Since  settlement  of  
the  notes  is  expected  in  the  foreseeable  future,  and  
our  subsidiary  has  been  consistently  making  timely  
payments  on  the  loans,  the  loans  are  considered  
foreign-currency transactions. Therefore the associated 
foreign  exchange  gains  and  losses  are  recognized  as 
other income or expense rather than being deferred in 
the cumulative translation account in other comprehen-
sive income.

Purchase Commitments
We  have  entered  into  unconditional  purchase  obliga-
tions,  which  include  noncancelable  purchase  commit-
ments and take-or-pay arrangements with suppliers. We 
review our agreements and make an assessment of the 
likelihood of a shortfall in purchases and determine if it 
is necessary to record a liability.

Revenue Recognition
Revenue from CMP consumable products is recognized 
when  title  is  transferred  to  the  customer,  provided 
acceptance  and  collectibility  are  reasonably  assured. 
Title  transfer  generally  occurs  upon  shipment  to  the 
customer  or  when  inventory  held  on  consignment  is 
consumed  by  the  customer,  subject  to  the  terms  and 
conditions of the particular customer arrangement. We 
have  consignment  agreements  with  a  number  of  our 
customers  that  require,  at  a  minimum,  monthly  con-
sumption reports that enable us to record revenue and 
inventory usage in the appropriate period.

We  market  our  products  through  distributors  in  a  few 
areas  of  the  world.  We  recognize  revenue  upon  ship-
ment and when title is transferred to the distributor. We 
do  not  have  any  arrangements  with  distributors  that 
include  payment  terms,  rights  of  return,  or  rights  of 
exchange outside the normal course of business, or any 
other significant matters that would impact the timing of 
revenue recognition.

Within  our  Engineered  Surface  Finishes  (ESF)  business, 
sales of equipment are recorded as revenue upon deliv-
ery.  Amounts  allocated  to  installation  and  training  are 
deferred  until  those  services  are  provided  and  are  not 
material.

Revenues  are  reported  net  of  any  value-added  tax  or 
other such tax assessed by a governmental authority on 
our revenue-producing activities.

Shipping and Handling
Costs  related  to  shipping  and  handling  are  included  in 
cost of goods sold.

Research, Development and Technical
Research, development and technical costs are expensed 
as incurred and consist primarily of staffing costs, mate-
rials and supplies, depreciation, utilities and other facili-
ties costs.

Income Taxes
Current  income  taxes  are  determined  based  on  esti-
mated  taxes  payable  or  refundable  on  tax  returns  for 
the current year. Deferred income taxes are determined 
using enacted tax rates for the effect of temporary dif-
ferences  between  the  book  and  tax  bases  of  recorded 
assets  and  liabilities.  The  effect  on  deferred  tax  assets  

38

39

and  liabilities  of  a  change  in  tax  rates  is  recognized  in 
income in the period that includes the enactment date. 
Provisions  are  made  for  both  U.S.  and  any  foreign 
deferred  income  tax  liability  or  benefit.  We  recognize 
the  tax  benefit  of  an  uncertain  tax  position  only  if  it  is 
more  likely  than  not  that  the  tax  position  will  be  sus-
tained by the taxing authorities, based on the technical 
merits of the position. In fiscal 2010, we elected to per-
manently reinvest the earnings of certain of our foreign 
subsidiaries outside the U.S. rather than repatriating the 
earnings to the U.S. See Note 16 for additional informa-
tion on income taxes.

Share-Based Compensation
We  record  share-based  compensation  expense  for  all 
share-based  awards,  including  stock  option  grants, 
restricted  stock  and  restricted  stock  unit  awards  and 
employee  stock  purchases.  We  calculate  share-based 
compensation expense using the straight-line approach 
based  on  awards  ultimately  expected  to  vest,  which 
requires  the  use  of  an  estimated  forfeiture  rate.  Our 
estimated forfeiture rate is primarily based on historical 
experience,  but  may  be  revised  in  future  periods  if 
actual  forfeitures  differ  from  the  estimate.  We  use  the 
Black-Scholes  option-pricing  model  to  estimate  the 
grant date fair value of our stock options and employee 
stock purchases. This model requires the input of highly 
subjective assumptions, including the option’s expected 
term, the price volatility of the underlying stock, the risk-
free interest rate and the expected dividend rate, if any. 
A small change in the underlying assumptions can have 
a  relatively  large  effect  on  the  estimated  valuation.  We 
estimate the expected volatility of our stock based on a 
combination  of  our  stock’s  historical  volatility  and  the 
implied  volatilities  from  actively-traded  options  on  our 
stock.  We  calculate  the  expected  term  of  our  stock 
options using the simplified method, due to our limited 
amount of historical option exercise data, and we add a 
slight  premium  to  this  expected  term  for  employees 
who  would  meet  the  definition  of  retirement  eligible 
pursuant to the terms of their grant agreements during 
the contractual term of the grant. The simplified method 
uses an average of the vesting term and the contractual 
term of the option to calculate the expected term. The 
risk-free  rate  is  derived  from  the  U.S.  Treasury  yield 
curve in effect at the time of grant.

For  additional  information  regarding  our  share-based

Earnings Per Share
Basic  earnings  per  share  (EPS)  is  calculated  by  dividing 
net  income  available  to  common  stockholders  by  the 
weighted-average number of common shares outstand-
ing during the period. Diluted EPS is calculated by using  

the  weighted-average  number  of  common  shares  out-
standing  during  the  period  increased  to  include  the 
weighted-average  dilutive  effect  of  “in-the-money” 
stock options and unvested restricted stock shares using 
the treasury stock method.

Comprehensive Income
Comprehensive income primarily differs from net income 
due to foreign currency translation adjustments.

Effects of Recent Accounting Pronouncements
On October 1, 2009, we adopted new accounting stan-
dards  for  the  accounting  and  reporting  of  minority 
equity  interests  in  subsidiaries.  Minority  interests  are 
charac terized  as  noncontrolling  interests  and  are 
reported  as  a  component  of  equity  separate  from  the 
parent’s  equity,  and  purchases  or  sales  of  equity  inter-
ests  that  do  not  result  in  a  change  of  control  are 
accounted  for  as  equity  transactions.  In  addition,  net 
income  attributable  to  the  noncontrolling  interest  is 
included in consolidated net income on the face of the 
statement of income and, upon loss of control, the inter-
est sold, as well as any interest retained, is recorded at 
fair  value  with  any  gain  or  loss  recognized  in  earnings. 
The  new  standards  apply  prospectively,  except  for  the 
presentation  and  disclosure  requirements,  which  apply 
retrospectively. The adoption of these standards had no 
effect on our results of operations, financial position or 
cash flows as we currently have no minority interests in 
any of our subsidiaries.

In June 2009, the Financial Accounting Standards Board 
(FASB)  issued  new  standards  prescribing  the  informa-
tion that a reporting entity must provide in its financial 
reports  about  the  transfer  of  financial  assets.  The  new 
standards  amend  previous  guidance  by  removing  the 
concept  of  a  qualifying  special-purpose  entity  and 
removing the exception from applying the provisions of 
accounting for variable interest entities that are qualify-
ing  special-purpose  entities.  The  new  standards  are 
effective for transfers of financial assets occurring on or 
after  January  1,  2010.  The  adoption  of  these  new  stan-
dards did not have any impact on our results of opera-
tions, financial position or cash flows.

In June 2009, the FASB issued new standards regarding 
the  recognition  of  a  controlling  financial  interest  in  a 
variable interest entity (VIE). The primary beneficiary of 
a  VIE  is  defined  as  the  enterprise  that  has  both:  1)  the 
power to direct the activities of a VIE that most signifi-
cantly impact the entity’s economic performance; and 2) 
the obligation to absorb losses of the entity that could 
potentially  be  significant  to  the  VIE  or  the  right  to 
receive benefits from the entity that could potentially be 
significant  to  the  VIE.  The  new  standards  also  require 
ongoing reassessments of whether an  enterprise is the  

40

41

primary  beneficiary  of  a  VIE.  The  new  standards  are 
effective  for  annual  reporting  periods  beginning  after 
November  15,  2009  and  for  interim  reporting  periods 
within  the  first  annual  reporting  period.  We  do  not 
believe the adoption of these new standards will have a 
material  impact  on  our  results  of  operations,  financial 
position  or  cash  flows.  We  do  not  currently  have  any 
interest  or  arrangements  that  are  considered  variable 
interest entities.

In  October  2009,  the  FASB  issued  ASU  No.  2009-13, 
“Revenue Recognition (Topic 605)—Multiple-Deliverable 
Revenue  Arrangements”  (ASU  2009-13),  a  consensus  of 
the FASB Emerging Issues Task Force. The guidance in 
ASU  2009-13  modifies  the  fair  value  requirements 
regarding  the  recognition  of  revenue  under  multiple 
element  arrangements  by  allowing  the  use  of  the  best 
estimate  of  selling  price  in  addition  to  vendor-specific 
objective  evidence  (VSOE)  and  third-party  evidence 
(TPE)  for  determining  the  selling  price  of  a  deliverable. 
A vendor is now required to use its best estimate of the 
selling price when VSOE or TPE of the selling price can-
not be determined. In addition, the residual method of 
allocating  arrangement  consideration  is  no  longer  per-
mitted. ASU 2009-13 is effective prospectively for reve-
nue  arrangements  entered  into  or  modified  in  fiscal 
years  beginning  on  or  after  June  15,  2010.  We  do  not 
believe the adoption of ASU 2009-13 will have a material 
effect on our results of operations, financial position or 
cash flows.

In October 2009, the FASB issued Accounting Standards 
Update  (ASU)  No.  2009-14,  “Software  (Topic  985)—
Certain  Revenue  Arrangements  that  Include  Software 
Elements”  (ASU  2009-14),  a  consensus  of  the  FASB 
Emerging Issues Task Force. The guidance in ASU 2009-
14 modifies the existing accounting rules regarding the 
recognition  of  revenue  from  the  sale  of  software  to 
exclude: (a) non-software components of tangible prod-
ucts; and (b) software components of tangible products 
that are sold, licensed, or leased with tangible products 
when  the  software  components  and  non-software  
components  of  the  tangible  product  function  together 
to deliver the tangible product’s essential functionality. 
ASU  2009-14  is  effective  prospectively  for  revenue 
arrangements  entered  into  or  modified  in  fiscal  
years  beginning  on  or  after  June  15,  2010.  We  do  not 
believe the adoption of ASU 2009-14 will have a material 
effect on our results of operations, financial position or 
cash flows.

In January 2010, the FASB issued ASU No. 2010-06, “Fair 
Value  Measurements  and  Disclosures  (Topic  820)—
Improving Disclosures about Fair Value Measurements”  
(ASU  2010-06).  ASU  2010-06  provides  amendments  to  

the rules regarding the disclosure of fair value measure-
ments and clarifies the language in certain existing dis-
closures.  New  disclosures  include  a  discussion  of  the 
transfers  in  and  out  of  Level  1  and  2  measurements  as 
well as a reconciliation of gross activity for Level 3 mea-
surements.  ASU  2010-06  clarifies  the  disclosures  an 
entity  must  make  regarding  inputs  and  valuation  tech-
niques  used  in  fair  value  measurements.  The  ASU  also 
clarifies  that  an  entity  should  provide  fair  value  disclo-
sures for each class of assets and liabilities. ASU 2010-06 
is  effective  for  interim  and  annual  reporting  periods 
beginning after December 15, 2009, except for the dis-
closures  about  the  reconciliation  of  Level  3  measure-
ments which are effective for fiscal years beginning after 
December  15,  2010.  The  adoption  of  the  provisions 
relating  to  Level  1  and  Level  2  measurements  did  not 
have  a  material  impact  on  our  results  of  operations, 
financial position or cash flows. We are currently assess-
ing the potential impact that the adoption of the provi-
sions related to Level 3 measurements will have on the 
disclosures in our financial statements.

3. Business Combinations
All  business  combinations  have  been  accounted  for 
under the purchase method of accounting. Accordingly, 
the  assets  and  liabilities  of  the  acquired  entities  are 
recorded  at  their  estimated  fair  values  at  the  date  of 
acquisition.  Goodwill  represents  the  excess  of  the  pur-
chase price over the fair value of net assets and amounts 
assigned to identifiable intangible assets. Purchased in-
process  research  and  development  (IPR&D),  for  which 
technological  feasibility  has  not  yet  been  established 
and no future alternative uses exist, has been expensed 
immediately.  In  December  2007,  the  FASB  issued  new 
standards for the accounting for business combinations. 
The  new  standards  retain  the  purchase  method  of 
accounting  for  acquisitions,  but  require  a  number  of 
changes, including changes in the way assets and liabili-
ties  are  recognized  in  purchase  accounting.  They  also 
change the recognition of assets acquired and liabilities 
assumed arising from contingencies, require the capital-
ization  of  IPR&D  at  fair  value,  and  require  acquisition-
related costs to be charged to expense as incurred. The 
new standards were effective for us October 1, 2009 and 
will apply prospectively to business combinations com-
pleted on or after that date.

On February 27, 2009, we completed the acquisition of 
Epoch Material Co., Ltd. (Epoch), which previously was a 
consolidated  subsidiary  of  Eternal  Chemical  Co.,  Ltd. 
(Eternal). Epoch is a Taiwan-based company specializing 
primarily  in  the  development,  manufacture  and  sale  of  
copper  CMP  consumables.  We  paid  $59,391  to  obtain 
90%  of  Epoch’s  stock,  plus  $728  of  transaction  costs,  

40

41

from our available cash balance. We paid an additional 
$6,600 from an escrow account which was held in Taiwan 
to Eternal in August 2010 to acquire the remaining 10% 
of  Epoch’s  stock.  During  this  interim  period,  Eternal 
held  the  remaining  10%  ownership  interest  in  Epoch. 
However,  Eternal  waived  rights  to  any  interest  in  the 
earnings  of  Epoch  during  the  interim  period,  including 
any  associated  dividends.  Consequently,  we  have 
recorded  100%  of  Epoch’s  results  of  operations  from 
February 27, 2009 through the end of our fiscal 2010 in 
our  Consolidated  Statement  of  Income,  rather  than 
recording any noncontrolling interest in Epoch.

The purchase price for Epoch was allocated to tangible 
assets,  liabilities  assumed,  identified  intangible  assets 
acquired, as well as IPR&D, based on our estimation of 
their fair values. The excess of the purchase price over the 
aggregate  fair  values  was  recorded  as  goodwill  and  is 
generally fully deductible for  tax purposes.  The  follow-
ing table summarizes the final purchase price allocation.

ments  to  net  income  to  give  effect  to:  expensing  of 
IPR&D  on  October  1,  2008  and  2007;  amortization  of 
intangible  assets  acquired;  depreciation  of  property, 
plant and equipment acquired; and income taxes.

4. Fair Value of Financial Instruments
On  October  1,  2008,  we  adopted  various  accounting 
standards issued by the FASB for the fair value measure-
ment of all financial assets and financial liabilities. These 
standards established a common definition for fair value 
in generally accepted accounting principles, established 
a  framework  for  measuring  fair  value  and  expanded  
disclosure  about  such  fair  value  measurements.  These 
standards also clarified the application of fair value mea-
surement  in  an  inactive  market  and  illustrated  how  an 
entity would determine fair value when the market for a 
financial asset is not active. These standards allow mea-
surement  at  fair  value  of  eligible  financial  assets  and 
financial  liabilities  that  are  not  otherwise  measured  at 
fair value on an instrument-by-instrument basis (the “fair 
value option”). We did not elect the fair value option for 
any  financial  assets  or  financial  liabilities  that  were  not 
previously  required  to  be  measured  at  fair  value  under 
other  generally  accepted  accounting  principles.  On 
October 1, 2009, we adopted the accounting provisions 
that  relate  to  non-financial  assets  and  non-financial  lia-
bilities. The adoption of these provisions did not have a 
material  impact  on  our  results  of  operations,  financial 
position  or  cash  flows.  We  did  not  elect  the  fair  value 
option for any non-financial assets or non-financial liabil-
ities  that  were  not  previously  required  to  be  measured 
at fair value under other generally accepted accounting 
principles.

Fair value is defined as the price that would be received 
from the sale of an asset or paid to transfer a liability (an 
exit price) in the principal or most advantageous market 
for the asset or liability in an orderly transaction between 
market  participants  on  the  measurement  date.  The 
FASB  established  a  three-level  hierarchy  for  disclosure 
based on the extent and level of judgment used to esti-
mate  fair  value.  Level  1  inputs  consist  of  valuations 
based  on  quoted  market  prices  in  active  markets  for 
identical  assets  or  liabilities.  Level  2  inputs  consist  of 
valuations  based  on  quoted  prices  for  similar  assets  or 
liabilities, quoted prices for identical assets or liabilities 
in an inactive market, or other observable inputs. Level 
3  inputs  consist  of  valuations  based  on  unobservable 
inputs that are supported by little or no market activity. 
Effective April 1, 2009, we adopted new fair value stan-
dards  issued  by  the  FASB  which  require  disclosures 
about  fair  value  of  financial  instruments  in  interim 
reporting  periods  as  well  as  in  annual  financial  state-
ments  and  require  fair  value  disclosures  in  summarized 
financial information at interim periods.

The  following  tables  present  financial  assets  that  we 
measured at fair value on a recurring basis at September 
30,  2010  and  2009.  As  permitted  under  the  relevant 
standards,  we  have  chosen  to  not  measure  any  of  our 
liabilities at fair value as we believe our liabilities approx-
imate their fair value due to their short-term, highly liq-
uid  characteristics.  We  have  classified  the  following 
assets  in  accordance  with  the  fair  value  hierarchy  set 
forth in the applicable standards. In instances where the 
inputs used to measure the fair value of an asset fall into 
more than one level of the hierarchy, we have classified 
them based on the lowest level input that is significant 
to the determination of the fair value.

Our  cash  and  cash  equivalents  consist  of  various  bank 
accounts  used  to  support  our  operations  and  invest-
ments  in  institutional  money-market  funds  which  are 
traded in active markets. The recorded amounts of cash, 
accounts receivable and accounts payable approximate 
their  fair  values  due  to  their  short-term,  highly  liquid 
characteristics.  The  fair  value  of  our  long-term  ARS  is 
determined through two discounted cash flow analyses, 
one using a discount rate based on a market index com-
prised  of  tax  exempt  variable  rate  demand  obligations 
and one using a discount rate based on the LIBOR swap 
curve,  adding  a  risk  factor  to  reflect  current  liquidity 
issues in the ARS market.

Effective  April  1,  2009,  we  adopted  accounting  stan-
dards  issued  by  the  FASB  regarding  the  classification 
and valuation of financial instruments, including the rec-
ognition  and  presentation  of  other-than-temporary 
impairments  for  investment  securities  we  own  and  the  

determination of fair value of financial instruments when 
the volume of trading activity significantly decreases. A 
debt security is considered to be impaired when the fair 
value of the debt security is less than its amortized cost 
at  the  balance  sheet  date.  An  other-than-temporary 
impairment must be recorded when a credit loss exists; 
that  is  when  the  present  value  of  the  expected  cash 
flows  from  a  debt  security  is  less  than  the  amortized 
cost basis of the security. An impairment is considered 
to be other-than-temporary when: 1) an entity intends to 
sell  a  debt  security  that  is  impaired;  2)  when  it  is  more 
likely than not that an entity will be required to sell the 
security before the recovery of its amortized cost basis; 
or 3) when a credit loss exists. An entity must recognize 
an  impairment  related  to  any  of  the  three  of  these  cir-
cumstances currently in earnings.

We  applied  these  standards  to  the  valuation  of  our 
investment  in  ARS  at  September  30,  2010.  Our  ARS 
investments at September 30, 2010 consisted of two tax 
exempt municipal debt securities with a total par value 
of $8,300. The ARS market began to experience illiquid-
ity  in  early  2008,  and  this  illiquidity  continues.  Despite 
this lack of liquidity, there have been no defaults of the 
underlying securities and interest income on these hold-
ings  continues  to  be  received  on  scheduled  interest 
payment  dates.  Our  ARS,  when  purchased,  were  gen-
erally  issued  by  A-rated  municipalities.  Although  the 
credit  ratings  of  both  municipalities  have  been  down-
graded since our original investment, the ARS are credit 
enhanced with bond insurance and carried a credit rat-
ing of AAA by Standard and Poors as of September 30, 
2010.  The  credit  rating  of  the  insurer  was  downgraded 
by  Standard  and  Poors  in  October  2010  from  AAA  to 
AA-plus.  We  incorporated  this  downgrade  into  our  
valuation  model  and  the  downgrade  did  not  materially 
affect the valuation of our ARS as of September 30, 2010.

Since an active market for ARS does not currently exist, 
we determine the fair value of these investments using a 
Level 3 discounted cash flow analysis and also consider 
other  factors  such  as  the  reduced  liquidity  in  the  ARS 
market and nature and quality of the insurance backing. 
Key  inputs  to  our  discounted  cash  flow  model  include 
projected  cash  flows  from  interest  and  principal  pay-
ments  and  the  weighted  probabilities  of  improved 
liquidity or debt refinancing by the issuer. We also incor-
porate certain Level 2 market indices into the discounted 
cash flow analysis, including published rates such as the  

42

43

LIBOR rate, the LIBOR swap curve and a municipal swap 
index published by the Securities Industry and Financial 
Markets  Association.  The  following  table  presents  a  
reconciliation  of  the  activity  in  fiscal  2010  for  fair  value 
measurements using level 3 inputs:

Balance as of October 1, 2009
Net sales of ARS

Balance as of September 30, 2010

$ 8,166
(50)

$ 8,066

Based on our fair value assessment, we determined that 
one ARS continues to be impaired as of September 30, 
2010.  This  security  has  a  fair  value  of  $3,166  (par  value 
$3,350). We assessed the impairment in accordance with 
the  applicable  standards  and  determined  that  the 
impairment  was  due  to  the  lack  of  liquidity  in  the  ARS 
market  rather  than  to  credit  risk.  We  have  maintained 
the $234 temporary impairment that we first recorded in 
fiscal 2008. We believe that this ARS is not permanently 
impaired  because  in  the  event  of  default  by  the  issuer, 
we  expect  the  insurance  provider  would  pay  interest 
and principal following the original repayment schedule, 
we were able to successfully monetize at par value $50 
of this security during our fiscal quarter ended March 31, 
2010, and we do not intend to sell the security nor do we 
believe  we  will  be  required  to  sell  the  security  before 
the value recovers, which may be at maturity. We deter-
mined  that  the  fair  value  of  the  other  ARS  was  not 
impaired as of September 30, 2010. See Note 8 for more 
information on these investments.

finished goods based on the higher level of demand for 
our products in fiscal 2010.

$23,114  for  the  years  ended  September  30,  2010,  2009 
and 2008, respectively.

In fiscal 2009, we recorded $1,245 in impairment expense 
primarily  related  to  the  decision  to  write-off  certain 
research  and  development  equipment  in  accordance 
with the applicable accounting standards for the impair-
ment and disposal of long-lived assets. Of this amount, 
$22 and $1,223 was included in cost of goods sold and 
research,  development  and  technical  expense,  respec-
tively. Impairment expense for fiscal 2010 and 2008 was 
not material.

7. Goodwill and Other Intangible Assets
Goodwill was $40,436 and $39,732 as of September 30, 
2010 and 2009, respectively. The increase in goodwill 
resulted  from  $832  in  foreign  exchange  fluctuation  of 
the  New  Taiwan  dollar  related  to  goodwill  associated 
with  the  Epoch  acquisition,  partially  offset  by  a  $128 
adjustment  to  record  the  tax  effect  of  the  difference 
between  goodwill  recorded  for  accounting  purposes 
and  goodwill  recorded  for  tax  purposes  related  to  the 
Epoch acquisition.

In fiscal 2010, other intangible assets increased by $323 
due to foreign exchange fluctuations of the New Taiwan 
dollar  related  to  intangible  assets  associated  with  the 
Epoch acquisition and we acquired $515 in other intan-
gible  assets.  In  fiscal  2009,  changes  in  the  amounts 
recorded as other intangible assets included $11,510 of 
intangible assets added as a result of our acquisition of 
Epoch and an increase of $1,075 due to foreign exchange 
fluctuations  of  the  New  Taiwan  dollar  on  the  Epoch 
intangible assets. In conjunction with the Epoch acquisi-
tion,  we  acquired  $2,520  in  product  technology  assets 
with an average useful life of seven years and we acquired 
$8,990 in fair value of customer relationships and other 
intangible assets with a weighted-average useful life of 
approximately  nine  years.  We  also  purchased  $1,410  of 
IPR&D related to one project. The amount allocated to 
IPR&D  was  determined  through  established  valuation 
techniques and was expensed upon acquisition because 
technological  feasibility  had  not  yet  been  established 
and no alternative future uses existed.

Goodwill and indefinite lived intangible assets are tested 
for  impairment  annually  in  the  fourth  fiscal  quarter  or 
more  frequently  if  indicators  of  potential  impairment 
exist,  using  a  fair-value-based  approach.  The  recover-
ability  of  goodwill  is  measured  at  the  reporting  unit 
level,  which  is  defined  as  either  an  operating  segment 
or one level below an operating segment. We have con-
sistently determined the fair value of our reporting units 
using  a  discounted  cash  flow  analysis  of  our  projected 
future results. The recoverability of indefinite lived intan-
gible  assets  is  measured  using  the  royalty  savings 
method. The use of discounted projected future results 
is  based  on  assumptions  that  are  consistent  with  our 
estimates of future growth within the strategic plan used 
to  manage  the  underlying  business.  Factors  requiring 
significant  judgment  include  assumptions  related  to 
future  growth  rates,  discount  factors,  royalty  rates  and 
tax  rates,  among  others.  Changes  in  economic  and  
operating conditions that occur after the annual impair-
ment  analysis  or  an  interim  impairment  analysis  that  
impact  these  assumptions  may  result  in  future 

impairment charges. As a result of the review performed 
in the fourth quarter of fiscal 2010, we determined that 
there was no impairment of our goodwill and intangible 
assets as of September 30, 2010.

Amortization expense was $2,426, $2,522 and $2,837 for 
fiscal  2010,  2009  and  2008,  respectively.  Estimated 
future amortization expense for the five succeeding fis-
cal years is as follows:

As discussed in Note 4 of this Form 10-K, the two ARS 
that  we  owned  as  of  September  30,  2010  are  classified 
as  long-term  investments.  The  securities  are  credit 
enhanced  with  bond  insurance  to  a  AAA  credit  rating 
from Standard and Poors as of September 30, 2010, and 
all interest payments continue to be received on a timely 
basis. The credit rating of the insurer was downgraded 
by  Standard  and  Poors  in  October  2010  from  AAA  to 
AA-plus. We incorporated this downgrade into our valu-
ation  model  and  this  downgrade  did  not  materially  
affect  the  valuation  of  our  ARS  as  of  September  30, 
2010. Although we believe these securities will ultimately 
be  collected  in  full,  we  believe  that  it  is  not  likely  that  
we  will  be  able  to  monetize  the  securities  in  our  next 
business  cycle  (which  for  us  is  generally  one  year).  We 

44

45

maintain a $234 pretax reduction ($151 net of tax) in fair  
value  on  the  other  ARS  that  we  had  recognized  as  of 
September  30,  2009.  We  assessed  the  impairment  and 
determined  that  the  impairment  was  temporary  as  it 
was related to the illiquid ARS market rather than credit 
risk.  In  addition,  we  continue  to  believe  this  decline  in 
fair value is temporary based on the nature of the under-
lying debt, the presence of bond insurance, our expec-
tation  that  the  issuer  may  refinance  its  debt,  the  fact 
that all interest payments have been received, our suc-
cessful monetization of $50 of this ARS during the quar-
ter  ended  March  31,  2010,  and  our  intention  not  to  sell 
the  security  nor  be  required  to  sell  the  security  until  
the value recovers, which may be at maturity, given our 
current  cash  position,  our  expected  future  cash  flow, 
and our unused debt capacity.

9.  Accrued Expenses and Other  

Current Liabilities

Accrued expenses and other current liabilities consisted 
of the following:

Accrued compensation
Goods and services received,  
  not yet invoiced
Warranty accrual
Taxes, other than income taxes

The  increase  in  accrued  compensation  was  primarily 
due to accruals for the annual incentive bonus program 
for  fiscal  2010.  This  increase  was  partially  offset  by  a 

reduction  in  accrued  expenses  related  to  our  payment 
of $6,600 out of an escrow account in Taiwan in August 
2010  to  acquire  the  remaining  10%  of  Epoch  stock,  as 
further explained in Note 3.

10. Derivative Financial Instruments
On  January  1,  2009,  we  adopted  new  accounting  stan-
dards  regarding  disclosures  about  derivative  instru-
ments  and  hedging  activities.  These  standards  require 
enhanced disclosures about (a) how and why derivative 
instruments  are  used,  (b)  how  derivative  instruments 
and  related  hedged  items  are  accounted  for,  and  (c) 
how  derivative  instruments  and  related  hedged  items 
affect  our  financial  position,  financial  performance  and 
cash flows.

Periodically  we  enter  into  forward  foreign  exchange 
contracts  in  an  effort  to  mitigate  the  risks  associated 
with  currency  fluctuations  on  certain  foreign  currency 
balance  sheet  exposures.  Our  foreign  exchange  con-
tracts  do  not  qualify  for  hedge  accounting;  therefore, 
the  gains  and  losses  resulting  from  the  impact  of  cur-
rency exchange rate movements on our forward foreign 
exchange  contracts  are  recognized  as  other  income  or 
expense  in  the  accompanying  consolidated  income 
statements  in  the  period  in  which  the  exchange  rates 
change. We do not use derivative financial instruments 
for  trading  or  speculative  purposes.  In  addition,  all 
derivatives,  whether  designated  in  hedging  relation-
ships or not, are required to be recorded on the balance 
sheet at fair value. At September 30, 2010, we had one 
forward  foreign  exchange  contract  selling  Japanese  
yen  related  to  intercompany  notes  with  one  of  our  
subsidiaries  in  Japan  and  for  the  purpose  of  hedging 
the risk associated with a net transactional exposure in 
Japanese yen.

The fair value of our derivative instrument included in the Consolidated Balance Sheet was as follows:

11. Revolving Credit Facility
We have an unsecured revolving credit facility of $50,000 
with  an  option  to  increase  the  facility  up  to  $80,000. 
Pursuant to an amendment in October 2008, this agree-
ment  extends  to  November  2011,  with  an  option  to 
renew  for  two  additional  one-year  terms.  In  November 
2010, the scheduled termination date was extended by 
one  year  through  October  2012.  This  amendment  did 
not include any other material changes to the terms of the 
credit agreement. Under this agreement, interest accrues 
on any outstanding balance at either the lending institu-
tion’s base rate or the eurodollar rate plus an applicable 
margin.  We  also  pay  a  non-use  fee.  Loans  under  this 
facility are intended primarily for general corporate pur-
poses, including financing working capital, capital expen-
ditures  and  acquisitions.  The  credit  agreement  also 
contains  various  covenants.  No  amounts  are  currently 
outstanding under this credit facility and we believe we 
are currently in compliance with its covenants.

12. Share-Based Compensation Plans

Equity Incentive Plan
In  March  2004,  our  stockholders  approved  our  Second 
Amended  and  Restated  Cabot  Microelectronics 
Corporation  2000  Equity  Incentive  Plan  (the  “EIP”),  as 
amended  and  restated  September  23,  2008,  which  is 
administered  by  the  Compensation  Committee  of  the 
Board of Directors and is intended to provide manage-
ment with the flexibility to attract, retain and reward our 
employees, directors, consultants and advisors. The EIP 
allows for the granting of four types of equity incentive 
awards: stock options, restricted stock, restricted stock 
units and substitute awards. Substitute awards are those 
awards  that,  in  connection  with  an  acquisition,  may  be 
granted to employees, directors, consultants or advisors 
of  the  acquired  company,  in  substitution  for  equity 
incentives  held  by  them  in  the  seller  or  the  acquired 
company.  No  substitute  awards  have  been  granted  to 
date. The EIP authorizes up to 9,500,000 shares of stock 
to  be  granted  thereunder,  including  up  to  1,900,000 
shares in the aggregate of restricted stock or restricted 
stock  units  and  up  to  1,750,000  incentive  stock  options 
(ISO).  Shares  issued  under  our  share-based  compensa-
tion  plans  are  issued  from  new  shares  rather  than  from 
treasury shares.

Non-qualified  stock  options  issued  under  the  EIP  are 
generally  time-based  and  provide  for  a  ten-year  term, 
with  options  generally  vesting  equally  over  a  four-year  
period,  with  first  vesting  on  the  first  anniversary  of  the  

award date. Compensation expense related to our stock 
option  awards  was  $7,081,  $9,507  and  $12,381  in  fiscal  
2010,  2009  and  2008,  respectively.  For  additional  infor-
mation  on  our  accounting  for  share-based  compensa-
tion, see Note 2 to the consolidated financial statements. 
Under the EIP, employees and non-employees may also 
be granted ISOs to purchase common stock at not less 
than  the  fair  value  on  the  date  of  the  grant.  No  ISOs 
have been granted to date.

Under  the  EIP,  employees  and  non-employees  may  be 
awarded  shares  of  restricted  stock  or  restricted  stock 
units, which generally vest over a four-year period, with 
first  vesting  on  the  anniversary  of  the  grant  date.  In  
general,  shares  of  restricted  stock  and  restricted  stock 
units  may  not  be  sold,  assigned,  transferred,  pledged, 
disposed  of  or  otherwise  encumbered.  Holders  of 
restricted  stock,  and  restricted  stock  units,  if  specified  
in  the  award  agreements,  have  all  the  rights  of  stock-
holders, including voting and dividend rights, subject to 
the  above  restrictions,  although  the  current  holders  of 
restricted stock units do not have such rights. Restricted 
shares under the EIP also may be purchased and placed 
“on deposit” by executive officers pursuant to the 2001 
Deposit Share Plan. Shares purchased under this Deposit 
Share  Plan  receive  a  50%  match  in  restricted  shares 
(“Award Shares”). These Award Shares vest at the end of 
a  three-year  period,  and  are  subject  to  forfeiture  upon 
early  withdrawal  of  the  deposit  shares.  Compensation 
expense  related  to  our  restricted  stock  and  restricted 
stock unit awards and restricted shares matched at 50% 
pursuant  to  the  Deposit  Share  Plan  was  $4,134,  $2,893 
and $2,022 for fiscal 2010, 2009 and 2008, respectively.

Employee Stock Purchase Plan
In  March  2008,  our  stockholders  approved  our  2007 
Cabot  Microelectronics  Employee  Stock  Purchase  Plan 
(the  “ESPP”),  which  amended  the  ESPP  for  the  primary 
purpose of increasing the authorized shares of common 
stock  to  be  purchased  under  the  ESPP  from  475,000 
designated shares to 975,000 shares. The ESPP allows all 
full  and  certain  part-time  employees  of  Cabot  Micro-
electronics and its subsidiaries to purchase shares of our 
common  stock  through  payroll  deductions.  Employees 
can  elect  to  have  up  to  10%  of  their  annual  earnings 
withheld  to  purchase  our  stock,  subject  to  a  maximum 
number of shares that a participant may purchase and a 
maximum  dollar  expenditure  in  any  six-month  offering 
period, and certain other criteria. The provisions of the  
ESPP  allow  shares  to  be  purchased  at  a  price  no  less 
than the lower of 85% of the closing price at the begin-
ning or end of each semi-annual stock purchase period.  

46

47

Prior  to  January  1,  2009,  the  shares  were  purchased  at 
the maximum 15% discount. In conjunction with certain 
cost reduction initiatives we implemented in the second 
quarter  of  fiscal  2009,  the  ESPP  was  amended  as  of  
January 19, 2009 to suspend the 15% discount. Pursuant 
to  the  amended  ESPP,  effective  with  the  six-month 
period beginning January 1, 2009, the ESPP shares were 
purchased  at  a  price  equal  to  the  lower  of  the  closing 
price at the beginning or end of each semi-annual offer-
ing period. In light of improved economic and industry 
conditions, the ESPP was amended again as of January 
1, 2010 to reinstate the 15% discount effective January 1, 
2010.  A  total  of  38,050,  57,815,  and  54,625  shares  were 
issued under the ESPP during fiscal 2010, 2009 and 2008, 
respectively. Compensation expense related to the ESPP 
was $360, $324 and $508 in fiscal 2010, 2009 and 2008, 
respectively.

Directors’ Deferred Compensation Plan
The Directors’ Deferred Compensation Plan, as amended 
and  restated  September  23,  2008,  became  effective  in 
March  2001  and  applies  only  to  our  non-employee 
directors.  The  cumulative  number  of  shares  deferred 
under the plan was 45,572 and 43,671 as of September 
30, 2010 and 2009, respectively. Compensation expense 
related  to  our  Directors’  Deferred  Compensation  Plan 
was  $68,  $78  and  $156  for  fiscal  2010,  2009  and  2008, 
respectively.

Accounting for Share-Based Compensation
We  record  share-based  compensation  expense  for  all 
share-based  awards,  including  stock  option  grants, 
restricted  stock  and  restricted  stock  unit  awards  and 
employee  stock  purchases.  We  calculate  share-based 
compensation expense using the straight-line approach 
based  on  awards  ultimately  expected  to  vest,  which 
requires  the  use  of  an  estimated  forfeiture  rate.  Our 
estimated forfeiture rate is primarily based on historical 
experience,  but  may  be  revised  in  future  periods  if 
actual  forfeitures  differ  from  the  estimate.  We  use  the 
Black-Scholes  model  to  estimate  the  grant  date  fair 
value  of  our  stock  options  and  employee  stock  pur-
chases.  This  model  requires  the  input  of  highly  subjec-
tive  assumptions,  including  the  price  volatility  of  the 
underlying stock, the expected term of our stock options 
and the risk-free interest rate. We estimate the expected 
volatility of our stock options based on a combination of 
our stock’s historical volatility and the implied volatilities 
from actively-traded options on our stock. We calculate 
the expected term of our stock options using the simpli-
fied  method,  due  to  our  limited  amount  of  historical  

option  exercise  data,  and  we  add  a  slight  premium  to 
this expected term for employees who meet the defini-
tion  of  retirement  eligible  pursuant  to  their  grants  dur-
ing  the  contractual  term  of  the  grant.  The  simplified 
method  uses  an  average  of  the  vesting  term  and  the 
contractual term of the option to calculate the expected 
term. The risk-free rate is derived from the U.S. Treasury 
yield curve in effect at the time of grant.

The fair value of our share-based awards was estimated 
using the Black-Scholes model with the following weighted-
average assumptions:

The Black-Scholes model is primarily used in estimating 
the  fair  value  of  short-lived  exchange  traded  options 
that  have  no  vesting  restrictions  and  are  fully  transfer-
able.  Because  employee  stock  options  and  employee 
stock purchases have certain characteristics that are sig-
nificantly  different  from  traded  options,  and  because 
changes  in  the  subjective  assumptions  can  materially 
affect the estimated value, our use of the Black-Scholes 
model for estimating the fair value of stock options and 
employee stock purchases may not provide an accurate 
measure.  Although  the  value  of  our  stock  options  and 
employee  stock  purchases  are  determined  in  accor-
dance  with  applicable  accounting  standards  using  an 
option-pricing  model,  those  values  may  not  be  indica-
tive of the fair values observed in a willing buyer/willing 
seller market transaction.

The fair value of our restricted stock and restricted stock 
unit awards represents the closing price of our common 
stock  on  the  date  of  grant.  Share-based  compensation 
expense related to restricted stock and restricted stock 
unit awards is recorded net of expected forfeitures.

The  costs  presented  in  the  preceding  table  for  share-
based  compensation  expense  may  not  be  representa-
tive  of  the  total  effects  on  reported  income  for  future 
years. Factors that may impact future years include, but 
are not limited to, changes to our historical approaches 
to  long-term  incentives  such  as  described  above,  the 
timing  and  number  of  future  grants  of  share-based 
awards,  the  vesting  period  and  contractual  term  of 
share-based awards and types of equity awards granted. 
Further,  share-based  compensation  may  be  impacted 

by  changes  in  the  fair  value  of  future  awards  through 
variables  such  as  fluctuations  in  and  volatility  of  our 
stock  price,  as  well  as  changes  in  employee  exercise 
behavior and forfeiture rates.

Our  non-employee  directors  received  their  annual 
equity  award  in  March  2010.  In  conjunction  with  this 
award,  the  Board  of  Directors  and  respective  commit-
tees  of  the  Board  approved  non-material  revisions  to 
the terms of the relevant award agreements to provide 
for immediate vesting of the award at the time of termi-
nation of service for any reason other than by reason of 
Cause,  Death,  Disability  or  a  Change  in  Control,  as 
defined in the Cabot Microelectronics Corporation 2000 
Equity Incentive Plan, if at such time the non-employee 
director has completed an equivalent of at least two full 
terms  as  a  director  of  the  Company,  as  defined  in  the 
Company’s  bylaws.  Three  of  the  Company’s  non-
employee directors had completed at least two such full 
terms of service as of the date of the March 2010 award. 
Consequently, the requisite service period for the award 
has  already  been  satisfied  and  we  recorded  the  fair 
value  of  $442  of  the  awards  to  these  three  directors  to 
share-based compensation expense in the fiscal quarter 
ended  March  31,  2010  rather  than  recording  that 
expense over the four-year vesting period stated in the 
award agreement.

deductions  from  options  exercised  was  $175,  $24  and 
$310  for  fiscal  2010,  2009  and  2008,  respectively.  The 
total fair value of stock options vested during fiscal years 
2010,  2009  and  2008  was  $8,494,  $12,560  and  $11,848, 
respectively. As of September 30, 2010, there was $8,510 
of total unrecognized share-based compensation expense 
related  to  unvested  stock  options  under  the  EIP.  That 
cost  is  expected  to  be  recognized  over  a  weighted- 
average period of 2.5 years.

As of September 30, 2010, there was $6,045 of total unrec-
ognized share-based compensation expense related to 
nonvested  restricted  stock  awards  and  restricted  stock 
units under the EIP. That cost is expected to be recog-
nized over a weighted-average period of 2.5 years. The 
total fair values of restricted stock awards and restricted 
stock  units  vested  during  fiscal  years  2010,  2009  and 
2008 were $3,209, $2,471 and $1,449, respectively.

13. Savings Plan
Effective in May 2000, we adopted the Cabot Microelec-
tronics Corporation 401(k) Plan (the “401(k) Plan”), which 
is a qualified defined contribution plan, covering all eli-
gible U.S. employees meeting certain minimum age and 
eligibility  requirements,  as  defined  by  the  401(k)  Plan. 
Participants may make elective contributions of up to 60% 
of their eligible compensation. All amounts contributed 
by  participants  and  earnings  on  these  contributions  
are  fully  vested  at  all  times.  The  401(k)  Plan  provides  
for  matching  and  fixed  non-elective  contributions  by  

the  Company.  Under  the  401(k)  Plan,  the  Company  will 
match 100% of the first four percent of the participant’s 
eligible compensation and 50% of the next two percent 
of  the  participant’s  eligible  compen sation  that  is  con-
tributed, subject to limitations required by government 
regulations. On April 1, 2009, in conjunction with certain 
cost reduction initiatives we implemented in fiscal 2009, 
the  401(k)  Plan  was  amended  to  suspend  the  matching 
contribution made by the Company. In light of improved 
economic  and  industry  conditions,  effective  January  1, 
2010,  the  Plan  was  amended  again  to  reinstate  the 
matching  contribution.  Under  the  401(k)  Plan,  all  U.S. 
employees,  even  those  who  do  not  contribute  to  the 
401(k) Plan, receive a contribution by the Company in an 
amount equal to four percent of eligible compensation, 
and thus are participants in the 401(k) Plan. Participants 
are  100%  vested  in  all  Company  contributions  at  all 
times. The Company’s expense for the 401(k) Plan totaled 
$2,981,  $2,813  and  $3,780  for  the  fiscal  years  ended 
September 30, 2010, 2009 and 2008, respectively.

The  decrease  in  other  income,  net  in  fiscal  2010  was  
primarily  due  to  lower  interest  income  resulting  from 
lower  interest  rates  earned  on  our  cash  balances  and 
investments  compared  to  fiscal  2009,  and  the  foreign 
exchange  effects  on  revenues  and  expenses,  primarily 
related to changes in the exchange rate of the Japanese 
yen to the U.S. dollar, net of the gains and losses incurred 
on  forward  foreign  exchange  contracts  discussed  in 
Note 10 of this Form 10-K. The decrease in other income, 
net in fiscal 2009 compared to fiscal 2008 was primarily 
due to lower interest income resulting from lower inter-
est  rates  earned  on  our  lower  average  cash  and  ARS  
balances  compared  to  fiscal  2008.  We  monetized  the 
majority  of  our  investments  in  ARS  during  fiscal  2008 
and  reinvested  these  funds  into  money  market  invest-
ments which earn interest at lower rates.

Common Stock
Each share of common stock entitles the holder to one 
vote on all matters submitted to a vote of Cabot Micro-
electronics’  stockholders.  Common  stockholders  are 
entitled  to  receive  ratably  the  dividends,  if  any,  as  may 
be  declared  by  the  Board  of  Directors.  The  number  of 
authorized shares of common stock is 200,000,000 shares.

Stockholder Rights Plan
In  March  2000  the  Board  of  Directors  of  Cabot  Micro-
electronics  approved  a  stock  rights  agreement  and 
declared  a  dividend  distribution  of  one  right  to  pur-
chase one one-thousandth of a share of Series A Junior 
Participating Preferred Stock for each outstanding share 
of  common  stock  to  stockholders  of  record  on  April  7, 
2000. This rights agreement expired in April 2010 accord-
ing to its terms.

Share Repurchases
In  January  2008,  we  announced  that  our  Board  of 
Directors  had  authorized  a  share  repurchase  program 
for  up  to  $75,000  of  our  outstanding  common  stock. 
Shares  are  repurchased  from  time  to  time,  depending 
on  market  conditions,  in  open  market  transactions,  at 
management’s  discretion.  We  fund  share  repurchases 
from  our  existing  cash  balance.  The  program,  which 
became effective on the authorization date, may be sus-
pended  or  terminated  at  any  time,  at  the  Company’s 
discretion.  During  fiscal  2010,  we  repurchased  723,184 
shares of common stock at a cost of $24,998. We did not 
repurchase any shares under the share repurchase pro-
gram in fiscal 2009. During fiscal 2008, we repurchased a 
total  of  1,056,472  shares  of  common  stock  under  these 
programs  at  a  cost  of  $39,001.  For  additional  informa-
tion  on  share  repurchases,  see  Part  II,  Item  5,  “Market 
for  Registrant’s  Common  Equity,  Related  Stockholder 
Matters and Issuer Purchases of Equity Securities.”

Separate from this share repurchase program, a total of 
24,651  and  14,425  shares  were  purchased  during  fiscal 
2010  and  2009,  respectively,  pursuant  to  the  terms  of 
our  EIP  as  shares  withheld  from  award  recipients  to 
cover payroll taxes on the vesting of shares of restricted 
stock granted under the EIP.

In  fiscal  2010,  we  elected  to  permanently  reinvest  the 
earnings  of  certain  of  our  foreign  subsidiaries  outside 
the U.S. rather than repatriating the earnings to the U.S. 
We have not provided deferred taxes on approximately 
$14.1 million of undistributed earnings of such subsidiar-
ies. These earnings could become subject to additional 
income tax if they are remitted as dividends to the U.S. 
parent company, loaned to the U.S. parent company, or 
upon sale of subsidiary stock. This election reduced our 
effective  income  tax  rate  in  fiscal  2010  by  2.7  percent-
age  points.  Decreased  tax  expense  related  to  share-
based compensation also decreased our effective income 
tax rate. These decreases in our effective tax rate were 
partially offset by the present expiration of the research 
and  development  tax  credit  effective  December  31, 
2009, and lower tax-exempt interest income.

On  October  1,  2007,  we  adopted  the  standards  for  the 
accounting  for  uncertainty  in  income  taxes,  which  pre-
scribe  a  threshold  for  the  financial  statement  recogni-
tion and measurement of tax positions taken or expected 
to be taken on a tax return. Under these standards, we 
may recognize the tax benefit of an uncertain tax posi-
tion only if it is more likely than not that the tax position 
will be sustained by the taxing authorities, based on the 
technical merits of the position. Upon adoption, we rec-
ognized a $59 reduction to our beginning retained earn-
ings  balance  and  we  reclassified  $450  from  current 
income  taxes  payable  to  a  non-current  tax  liability  for 
unrecognized  tax  benefits,  including  interest  and  pen-
alties.  We  made  this  reclassification  to  a  non-current 
liability  because  settlement  was  not  expected  to  occur 
within one year of the balance sheet date.

The following table presents the changes in the balance 
of gross unrecognized tax benefits during the last three 
fiscal years:

We recognize interest and penalties related to uncertain 
tax positions as income tax expense in our financial state-
ments.  Interest  and  penalties  accrued  on  our  Consoli-
dated Balance Sheet were $6 and $25 at September 30, 
2010  and  2009,  respectively,  and  interest  and  penalties 
charged to expense were not material.

We believe the tax periods open to examination by the 
U.S. federal government include fiscal years 2007 through 
2009.  We  believe  the  tax  periods  open  to  examination 
by U.S. state and local governments include fiscal years 
2006 through 2009 and the tax periods open to exami-
nation  by  foreign  jurisdictions  include  fiscal  years  2003 
through 2009. We do not anticipate a significant change 
to the total amount of unrecognized tax benefits within 
the next 12 months.

Significant  components  of  deferred  income  taxes  were 
as follows:

17. Commitments and Contingencies

Legal Proceedings
While we are not involved in any legal proceedings that 
we  believe  will  have  a  material  impact  on  our  consoli-
dated  financial  position,  results  of  operations  or  cash 
flows, we periodically become a party to legal proceed-
ings in the ordinary course of business. For example, in 
January 2007, we filed a legal action against DuPont Air 
Products  NanoMaterials  LLC  (DA  Nano),  a  CMP  slurry 
competitor,  in  the  United  States  District  Court  for  the 
District of Arizona, charging that DA Nano’s manufactur-
ing and marketing of CMP slurries infringe certain CMP 
slurry patents that we own. The affected DA Nano prod-
ucts  include  certain  products  used  for  tungsten  CMP. 
We  filed  our  infringement  complaint  as  a  counterclaim 
in response to an action filed by DA Nano in the same 
court  in  December  2006  that  sought  declaratory  relief 
and alleged non-infringement, invalidity and unenforce-
ability  regarding  some  of  the  patents  at  issue  in  our 
complaint against DA Nano. DA Nano filed its complaint 
following  our  refusal  of  its  request  that  we  license  to  it 
our patents raised in its complaint. DA Nano’s complaint 
did not allege any infringement by our products of intel-
lectual  property  owned  by  DA  Nano.  From  June  14 
through  July  8,  2010,  a  jury  trial  for  the  case  was  held.  
All  of  Cabot  Microelectronics’  patents  at  issue  in  the 
case were found valid. However, the jury found that DA 
Nano’s  products  at  issue  do  not  infringe  the  asserted 
claims  of  these  patents.  In  November  2010,  we  filed  a 
Notice of Appeal regarding infringement, and DA Nano 
filed a cross-appeal. While the outcome of this and any 
legal matter cannot be predicted with certainty, we con-
tinue  to  believe  that  our  claims  and  defenses  in  the 
pending  action  are  meritorious,  and  we  intend  to  con-
tinue to pursue and defend them.

Product Warranties
We  maintain  a  warranty  reserve  that  reflects  manage-
ment’s best estimate of the cost to replace product that 
does  not  meet  customers’  specifications  and  perfor-
mance requirements, and costs related to such replace-
ment.  The  warranty  reserve  is  based  upon  a  historical 
product replacement rate, adjusted for any specific known 
conditions or circumstances. Additions and deductions 
to  the  warranty  reserve  are  recorded  in  cost  of  goods 
sold.  Our  warranty  reserve  requirements  changed  dur-
ing fiscal 2010 as follows:

the reporting period

$  375

Indemnification
In  the  normal  course  of  business,  we  are  a  party  to  a 
variety  of  agreements  pursuant  to  which  we  may  be 
obligated  to  indemnify  the  other  party  with  respect  to 
certain matters. Generally, these obligations arise in the 
context of agreements entered into by us, under which 
we  customarily  agree  to  hold  the  other  party  harmless 
against  losses  arising  from  items  such  as  a  breach  of 
certain representations and covenants including title to 
assets sold, certain intellectual property rights and cer-
tain environmental matters. These terms are common in 
the industries in which we conduct business. In each of 
these circumstances, payment by us is subject to certain 
monetary  and  other  limitations  and  is  conditioned  on 
the other party making an adverse claim pursuant to the 
procedures specified in the particular agreement, which 
typically allow us to challenge the other party’s claims.

We evaluate estimated losses for such indemnifications 
under  the  accounting  standards  related  to  contingen-
cies  and  guarantees.  We  consider  such  factors  as  the 
degree  of  probability  of  an  unfavorable  outcome  and 
the ability to make a reasonable estimate of the amount 
of loss. To date, we have not experienced material costs 
as a result of such obligations and, as of September 30, 
2010,  have  not  recorded  any  liabilities  related  to  such 
indemnifications  in  our  financial  statements  as  we  do 
not believe the likelihood of such obligations is probable.

Lease Commitments
We  lease  certain  vehicles,  warehouse  facilities,  office 
space, machinery and equipment under cancelable and 
noncancelable  leases,  all  of  which  expire  within  four 
years from now and may be renewed by us. Lease com-
mitments also include certain costs associated with our 
pad finishing operation located at Taiwan Semiconductor 
Manufacturing Company, which are accounted for as an 
operating  lease  which  is  currently  scheduled  to  end  in 
August  2012.  Rent  expense  under  such  arrangements 
during fiscal 2010, 2009 and 2008 totaled $2,480, $1,883 
and $1,726, respectively.

In  December  2001  we  entered  into  a  fumed  alumina 
supply agreement with Cabot Corporation under which 
we agreed to pay Cabot Corporation for the expansion 
of  a  fumed  alumina  manufacturing  facility  in  Tuscola, 
Illinois. The arrangement for the facility has been treated 
as a capital lease for accounting purposes and the pres-
ent  value  of  the  minimum  quarterly  payments  resulted 
in  an  initial  $9,776  lease  obligation  and  related  leased 
asset. The initial term of the agreement expired in Decem-
ber 2006, but it was renewed for another five-year term 
ending in December 2011.

Purchase Obligations
Purchase  obligations  include  our  take-or-pay  arrange-
ments  with  suppliers,  and  purchase  orders  and  other 
obligations  entered  into  in  the  normal  course  of  busi-
ness regarding the purchase of goods and services.

We purchase fumed silica primarily under a fumed silica 
supply  agreement  with  Cabot  Corporation,  our  former 
parent company that is not a related party, that became 
effective in January 2004, and was amended in September 
2006 and in April 2008, the latter of which extended the 
termination date of the agreement from December 2009 
to  December  2012  and  also  changed  the  pricing  and 
some  other  non-material  terms  of  the  agreement  to  
the benefit of both parties. The agreement will automat-
ically  renew  unless  either  party  gives  notice  of  non-
renewal. We are generally obligated to purchase fumed 
silica for at least 90% of our six-month volume forecast 
for  certain  of  our  slurry  products,  to  purchase  certain 
non-material minimum quantities every six months, and 
to  pay  for  the  shortfall  if  we  purchase  less  than  these 
amounts.  We  currently  anticipate  meeting  minimum 
forecasted  purchase  volume  requirements.  We  also 
operate under a fumed alumina supply agreement with 
Cabot Corporation which runs through December 2011. 
Purchase obligations include $7,352 of contractual com-
mitments  for  fumed  silica  and  fumed  alumina  under 
these contracts.

18. Earnings Per Share
The standards of accounting for earnings per share require companies to provide a reconciliation of the numer ator 
and  denominator  of  the  basic  and  diluted  earnings  per  share  computations.  Basic  and  diluted  earnings  per  share 
were calculated as follows:

Numerator:

Earnings available to common shares

Denominator:

Weighted-average common shares

(Denominator for basic calculation)

Weighted-average effect of dilutive securities:
  Share-based compensation

Diluted weighted-average common shares
(Denominator for diluted calculation)

For the twelve months ended September 30, 2010, 2009, and 2008, approximately 2.6 million, 3.9 million and 2.7 million 
shares, respectively, attributable to outstanding stock options were excluded from the calculation of diluted earnings 
per share because the exercise price of the options was greater than the average market price of our common stock 
and, therefore, their inclusion would have been anti-dilutive.

MANAGEMENT RESPONSIBILITY

The  accompanying  consolidated  financial  statements 
were  prepared  by  the  Company  in  conformity  with 
accounting  principles  generally  accepted  in  the  United 
States  of  America.  The  Company’s  management  is 
responsible for the integrity of these statements and of 
the underlying data, estimates and judgments.

The Company’s management establishes and maintains 
a system of internal accounting controls designed to 
provide  reasonable  assurance  that  its  assets  are  safe-
guarded from loss or unauthorized use, transactions are 
properly  authorized  and  recorded,  and  that  financial 
records  can  be  relied  upon  for  the  preparation  of  the 
consolidated financial statements. This system includes 
written policies and procedures, a code of business con-
duct  and  an  organizational  structure  that  provides  for 
appropriate division of responsibility and the training of 
personnel.  This  system  is  monitored  and  evaluated  on 
an ongoing basis by management in conjunction with its 
internal audit function.

The Company’s management assesses the effectiveness 
of  its  internal  control  over  financial  reporting  on  an 
annual  basis.  In  making  this  assessment,  management 
uses  the  criteria  set  forth  by  the  Committee  of  Spon-
soring  Organizations  of  the  Treadway  Commission  in 
Internal  Control—Integrated  Framework.  Management 
acknowledges,  however,  that  all  internal  control  sys-
tems, no matter how well designed, have inherent limi-
tations and can provide only reasonable assurance with 
respect  to  financial  statement  preparation  and  presen-
tation.  In  addition,  the  Company’s  independent  regis-
tered  public  accounting  firm  evaluates  the  Company’s 
internal  control  over  financial  reporting  and  performs 
such tests and other procedures as it deems necessary 
to  reach  and  express  an  opinion  on  the  fairness  of  the 
financial statements.

In  addition,  the  Audit  Committee  of  the  Board  of 
Directors  provides  general  oversight  responsibility  for 
the financial statements. Composed entirely of Directors 
who  are  independent  and  not  employees  of  the 
Company,  the  Committee  meets  periodically  with  the 
Company’s  management,  internal  auditors  and  the 
independent registered public accounting firm to review 
the  quality  of  financial  reporting  and  internal  controls, 
as  well  as  results  of  auditing  efforts.  The  internal  audi-
tors and independent registered public accounting firm 
have full and direct access to the Audit Committee, with 
and without management present.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures
Our  management,  with  the  participation  of  our  Chief 
Executive  Officer  (CEO)  and  Chief  Financial  Officer 
(CFO),  has  evaluated  the  effectiveness  of  the  design 
and operation of our disclosure controls and procedures 
(as defined in Rule 13a-15(e) under the Securities Exchange 
Act  of  1934,  as  amended  (“the  Exchange  Act”)),  as  of 
September 30, 2010. Based on that evaluation, our CEO 
and  CFO  have  concluded  that  our  disclosure  controls 
and  procedures  were  effective  to  ensure  that  infor-
mation  required  to  be  disclosed  in  our  Exchange  Act 
reports is recorded, processed, summarized and reported 
within the time periods specified in the SEC’s rules and 
forms,  and  to  ensure  that  such  information  is  accumu-
lated and communicated to management, including the 
CEO and CFO, as appropriate to allow timely decisions 
regarding required disclosure.

While  we  believe  the  present  design  of  our  disclosure 
controls  and  procedures  is  effective  enough  to  make 
known to our senior management in a timely fashion all 
material information concerning our business, we intend 
to continue to improve the design and effectiveness of 
our  disclosure  controls  and  procedures  to  the  extent 
necessary  in  the  future  to  provide  our  senior  manage-
ment  with  timely  access  to  such  material  information, 
and to correct any deficiencies that we may discover in 
the future, as appropriate.

Management’s Report on Internal Control Over 
Financial Reporting
Our  management  is  responsible  for  establishing  and 
maintaining  adequate  internal  control  over  financial 
reporting  for  the  Company.  Internal  control  over  finan-
cial reporting is defined in Rule 13a-15(f) or Rule 15d-15(f) 
promulgated under the Securities Exchange Act of 1934 
as  a  process  designed  by,  or  under  the  supervision  of, 
the  Company’s  CEO  and  CFO  to  provide  reasonable 
assurance regarding the reliability of our financial report-
ing  and  the  preparation  of  financial  statements  for 
external purposes in accordance with generally accepted 
accounting  principles  in  the  United  States  of  America. 
Internal control over financial reporting includes policies 
and  procedures  that:  pertain  to  the  maintenance  of 
records  that  in  reasonable  detail  accurately  and  fairly 
reflect  our  transactions  and  dispositions  of  the  Com-
pany’s assets; provide reasonable assurance  that trans-
actions  are  recorded  as  necessary  for  preparation  of  
our  financial  statements  in  accordance  with  generally 

accepted  accounting  principles;  provide  reasonable 
assurance  that  receipts  and  expenditures  of  Company 
assets are made in accordance with management autho-
rization;  and  provide  reasonable  assurance  that  unau-
thorized  acquisition,  use  or  disposition  of  Company 
assets that could have a material effect on our financial 
statements would be prevented or detected on a timely 
basis. Because of its inherent limitations, internal control 
over financial reporting may not prevent or detect mis-
statements. Also, projections of any evaluation of effec-
tiveness  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.

Our  management  evaluated  the  effectiveness  of  our 
internal  control  over  financial  reporting  based  on  the 
framework  in  Internal  Control—Integrated  Framework 
issued  by  the  Committee  of  Sponsoring  Organizations 
of  the  Treadway  Commission  (COSO).  Based  on  this 
evaluation,  our  management  concluded  that  the  Com-
pany’s  internal  control  over  financial  reporting  was 
effective  as  of  September  30,  2010.  The  effectiveness  
of the Company’s internal control over financial report-
ing  as  of  September  30,  2010  has  been  audited  by 
PricewaterhouseCoopers  LLP,  an  independent  regis-
tered  public  accounting  firm,  as  stated  in  their  attesta-
tion  report  which  appears  under  Item  8  of  this  Annual 
Report on Form 10-K.

Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over finan-
cial  reporting  that  occurred  during  our  most  recent  
fiscal  quarter  that  have  materially  affected,  or  are  rea-
sonably  likely  to  materially  affect,  our  internal  control 
over financial reporting.

Inherent Limitations on Effectiveness of Controls
Because  of  inherent  limitations,  our  disclosure  controls 
or  our  internal  control  over  financial  reporting  may  not 
prevent  all  errors  and  all  fraud.  A  control  system,  no 
matter  how  well  conceived  and  operated,  can  provide 
only reasonable, not absolute, assurance that the objec-
tives of the control system are met. Further, the design 
of  a  control  system  must  reflect  the  fact  that  there  are 
resource  constraints,  and  the  benefits  of  controls  must 
be  considered  relative  to  their  costs.  Because  of  the 
inherent limitations in all control systems, no evaluation 
of controls can provide absolute assurance that all con-
trol  issues  and  instances  of  fraud,  if  any,  within  the 
Company  have  been  detected.  These  inherent  limita-
tions  include  the  realities  that  judgments  in  decision-
making  can  be  faulty,  and  that  breakdowns  can  occur 
because of a simple error or mistake. Additionally, con-
trols can be circumvented by the individual acts of some 
persons, by collusion of two or more people or by man-
agement  override  of  the  controls.  The  design  of  any 

58

59

system  of  controls  also  is  based  in  part  upon  certain 
assumptions  about  the  likelihood  of  future  events,  and 
there can be no assurance that any design will succeed 
in  achieving  its  stated  goals  under  all  potential  future 
conditions; over time, controls may become inadequate 
because  of  changes  in  conditions,  or  the  degree  of 
compliance with policies or procedures may deteriorate. 
Because  of  the  inherent  limitations  in  a  cost-effective 
control system, misstatements due to error or fraud may 
occur and not be detected.

O U R   C O M P A N Y 

Cabot Microelectronics is the world’s leading supplier of chemical mechanical planarization (CMP) slurries and a 

growing CMP pad supplier to the semiconductor industry. Our CMP consumables products are used to level, 

smooth and remove excess material from the multiple layers of material that are deposited upon silicon wafers 

in the production of most semiconductor devices. This enables our customers to manufacture smaller, faster and 

more  complex  devices.  We  also  produce  slurries  for  the  data  storage  industry  that  are  used  to  polish  certain 

600

hard disk drive components, and we are pursuing a number of other demanding surface modification applications 

through our Engineered Surface Finishes business.  

400

The  global  semiconductor  industry  experienced  a  strong  rebound  in  2010,  driven  by  solid  global  consumer 

demand for items like smart phones and tablet computers, particularly in the vibrant Asia Pacific region, as well 

200

as  the  return  of  corporate  IT  spending.  We  benefited  from  this  strong  industry  environment,  posting  record 

revenue and diluted earnings per share in fiscal 2010. The solid execution of our strategies and key initiatives 

0

resulted in over 40 percent growth in total revenue, nearly 70 percent growth in our pad business, the introduction 

of next generation products in all major application areas and the receipt of customer supplier awards from four 

of the world’s top semiconductor manufacturers in 2010.

Note: Under accounting rules, the company began recording share-based compensation expense beginning in FY06. 
          Consequently, fiscal years prior to FY06 do not include share-based compensation expense. On average, share-based 
          compensation expense reduced diluted earnings per share by approximately 35 cents per year from FY06 through FY10.

We continue to partner with our customers to help them achieve their environmental goals. As we look to the 
future,  we  plan  to  further  reduce  the  environmental  impact  of  doing  business  by  strongly  encouraging  our 
suppliers to share our commitment to the environment, and we plan to measure the progress of these preferred 
suppliers. Through our own environmental initiatives, as well as through joint programs with our customers and 
suppliers, we strive to continue to be a trusted business partner and model corporate citizen with respect to 
environmental issues.
