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 
lead ing  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 seg-
ment— the development, manufacture and sale of CMP 
consumable  products.  We  develop,  produce  and  sell 
CMP  slurries  for  polishing  many  of  the  conducting  and 
insulating  materials  used  in  IC  devices,  and  also  for 
 polishing the disk substrates and magnetic heads used 
in  hard  disk  drives.  We  also  develop,  manufacture  and 
sell CMP polishing pads, which are used in conjunction 
with slurries in the CMP process. We also pursue other 
demanding  surface  modification  applications  through 
our  Engineered  Surface  Finishes  (ESF)  business  where 
we  believe  we  can  leverage  our  expertise  in  CMP  con-
sumables  for  the  semiconductor  industry  to  develop 
products  for  demanding  surface  applications  in  other 
industries.

CMP Process Within IC Device Manufacturing
IC devices, or “chips”, are components in a wide range 
of  electronic  systems  for  computing,  communications, 
manufacturing and transportation. Individual consumers 
most  frequently  encounter  IC  devices  as  microproces-
sors in their desktop or laptop computers and as memory 
chips  in  computers,  tablets,  smart  phones,  cell  phones 
and digital cameras. The multi-step manufacturing proc-
ess for IC devices typically begins with a circular wafer of 
pure silicon, 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 initial steps in the manufacturing process build 
transistors  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  prevent  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  func-
tional  IC  device  with  specific  characteristics.  When  the 
conducting wiring on one layer of the IC device is com-
pleted, another layer of insulating material is added. The 
process  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, including slur-
ries  and  pads,  for  IC  devices  is  primarily  based  on  the 
number of wafer starts by semiconductor manufacturers 
and the type and complexity of the IC devices they pro-
duce.  To  enhance  the  performance  of  IC  devices,  IC 
device  manufacturers  have  progressively  increased  the 
number  and  density  of  electronic  components  and 
 wiring layers in each IC device. This is typically done in 
conjunction with shrinking the key dimensions on an IC 
device  from  one  technology  generation,  or  “node”,  to 
another. As a result, the number of transistors, wires and 
the  number  of  discrete  wiring  layers  have  increased, 
increasing  the  complexity  of  the  IC  device  and  the 
related demand for CMP consumable products to polish 
those  devices.  As  semiconductor  technology  has 
advanced and performance requirements 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 combination 
of chemical reactions and mechanical abrasion, leaving 
minimal residue and 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 chemically and 
mechanically interact at an atomic level with the surface 
material  of  the  IC  device.  CMP  pads  are  engineered 
polymeric materials designed to distribute 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.  The 
CMP  process  is  performed  on  a  CMP  polishing  tool. 
During the CMP process, the wafer is held on a rotating 
carrier, which is pressed down against a CMP pad. The 
CMP  pad  is  attached  to  a  rotating  polishing  table  that 
spins  in  a  circular  motion.  A  CMP  slurry  is  continuously 
applied  to  the  polishing  pad  to  facilitate  and  enhance 
the polishing process. Hard disk drive and silicon wafer 
manufacturers  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  process. 
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 den-
sity of transistors and other electronic components than 
is possible without CMP. By enabling IC device manufac-
turers 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.  Improve-
ments in throughput and yield reduce an IC device man-
ufacturer’s unit production costs, and reducing costs is 
one of the highest priorities of a semiconductor manu-
facturer  as  the  return  on  its  significant  investment  in 
manufacturing capacity can be enhanced by lower unit 
costs.  More  broadly,  sustained  growth  in  the  semicon-
ductor industry traditionally has been fueled by enhanced 
performance  and  lower  unit  costs,  making  IC  devices 
more affordable in an expanding range of applications.

Precision Polishing
Through our ESF business, 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 enhancing the performance of surfaces is critical to 
success, such as for precision optics and electronic sub-
strates, including silicon and silicon-carbide wafers.

Many  of  the  production  processes  currently  used  in 
 precision machining and polishing have been based on 
traditional,  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, biomed-
ical and consumer imaging.

including tungsten, copper, tantalum (commonly referred 
to  as  “barrier”  which  is  used  in  copper  wiring  applica-
tions) and aluminum. Slurries for polishing tungsten are 
used  heavily  in  the  production  of  advanced  memory 
devices for a multitude of end applications such as com-
puters, tablets, MP3 players, cellphones, gaming devices, 
digital photography 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 cus-
tomers  greater  flexibility,  improved  performance  and  a 
reduced  cost  of  ownership.  Our  slurries  for  polishing 
copper and barrier materials are used in the production 
of  advanced  IC  logic  devices  such  as  microprocessors 
for computers, and devices for graphic systems, gaming 
systems  and  communication  devices,  as  well  as  in  the 
production of advanced memory 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.  Slurries  for  polishing 
aluminum  are  relatively  new  in  the  CMP  consumables 
market  and  are  used  in  the  most  advanced  transistor 
designs currently in production. We offer multiple prod-
ucts for each technology node to enable different inte-
gration 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,  such 
as  pre-metal  dielectric  (PMD)  and  shallow  trench  isola-
tion (STI), at advanced technology nodes.

We  develop,  produce  and  sell  CMP  polishing  pads, 
which are consumable materials that work in conjunction 
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 technol-
ogies are closely related and utilize the same technical, 
sales and support 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 

4

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. Our pad  product offerings 
include our EPIC D100 series of pads and our next gen-
eration D200 series.

CMP Consumables for the Data Storage Industry
We develop and produce CMP slurries for polishing cer-
tain  materials  that  are  used  in  the  production  of  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 technol-
ogy  and  manufacturing  capabilities  established  for  the 
semiconductor  industry.  We  believe  CMP  significantly 
improves the surface finish of these rigid disk coatings, 
resulting  in  greater  storage  capacity  of  the  hard  disk 
drive  systems,  and  also  improves  the  production  effi-
ciency  of  manufacturers  of  hard  disk  drives  by  helping 
increase  their  throughput  and  yield.  We  expanded  our 
manufacturing capacity for data storage applications in 
fiscal 2011 to accommodate the growth we have experi-
enced in this area of our business.

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. His tor i-
cally, advanced optics have been produced using labor-
intensive  artisanal  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 magnetic fluids 
and sophisticated computer technology to polish a vari-
ety  of  shapes  and  materials.  QED’s  metrology  systems 
use  Subaperture  Stitching  Interferometry  (SSI)  technol-
ogy that captures precise metrology data for large and/
or  strongly  curved  optical  parts  and  Aspheric  Stitching 
Interferometry  (ASI)  technology,  which  is  designed  to 
measure  increasingly  complex  shapes,  including  non-
spherical surfaces, or aspheres.

Strategy
We  collaborate  closely  with  our  customers  to  develop 
and manufacture products that offer innovative and reli-
able solutions to our customers’ challenges and we strive 
to consistently and reliably deliver and support these 
products around the world through what we believe is  
a  robust  global  infrastructure  and  supply  chain.  We 

 continue to focus on the execution of our primary strategy 
of  strengthening  and  growing  our  core  CMP  consum-
ables  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 
business in the optics and electronic substrates markets.

Strengthening and Growing Our Core CMP  
Consumables Business
We intend to grow our core CMP consumables business 
by  leveraging  the  capabilities  and  global  infrastructure 
we  have  developed  as  the  leader  in  the  CMP  slurry 
industry. We dedicate significant time and resources to 
new  product  innovation,  and  we  work  closely  with  our 
customers to deliver reliable solutions on a global scale 
that are designed to provide superior quality and lower 
overall  cost  of  ownership.  We  believe  our  strong  finan-
cial  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 Material Co., Ltd. (Epoch), a Taiwan-
based CMP consumable provider, in fiscal 2009.

Developing  Innovative  Solutions:  We  believe  that  tech-
nology  and  innovation  are  vital  to  success  in  our  CMP 
consumables  business  and  we  devote  significant 
resources  to  research  and  development.  We  need  to 
stay  ahead  of  the  rapid  technological  advances  in  the 
electronics  industry  in  order  to  deliver  a  broad  line  of 
CMP  consumables  products  that  meet  or  exceed  our 
customers’ evolving needs. We have established research 
and  development  facilities  in  the  United  States,  Japan, 
Taiwan, Singapore, and most recently in South Korea, in 
order  to  meet  our  customers’  technology  needs  on  a 
global basis.

In  fiscal  2011,  we  launched  a  number  of  new  products 
within  our  existing  slurry  and  polishing  pad  businesses 
that cross multiple applications over a range of technol-
ogy  nodes  and  we  have  also  expanded  our  offerings 
within  new  and  emerging  technology  areas.  Several  of 
our newest product offerings are discussed below:

•	 	We	have	expanded	our	solutions	within	our	tungsten	
slurry business due to the increasing importance of a 
“buff” step to address more stringent customer per-
formance and selectivity requirements. A buff step is 
a  short  polishing  step  for  minimal  material  removal 
that  complements  our  existing  tungsten  slurries  for 
bulk removal applications.

•	 	We	have	introduced	new	products	for	Through	Silicon	
Via (TSV) polishing. TSV is a new advancement in chip 
design where multiple layers of stacked IC devices are 
connected into three dimensional chips. This enables 
semiconductor manufacturers to add speed and per-
formance  to  IC  devices  without  having  to  reduce  the 
critical dimensions of the chip.

•	 	We	have	commercialized	CMP	solutions	for	emerging	
applications such as for High K Metal Gates, which uti-
lize aluminum CMP.

•	 	We	 have	 developed	 post	 CMP	 cleaning	 solutions,	
referred  to  as  the  Epoch  Clean  series,  which  are 
designed to deliver optimal post CMP wafer surface 
properties for more advanced applications.

Close Collaboration With Our Customers: We believe that 
building close relationships with our customers is 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 solutions, to integrate 
our products into their manufacturing processes, and to 
assist  them  with  supply,  warehousing  and  inventory 
management.  Our  customers  demand  a  highly  reliable 
supply  source,  and  we  believe  we  have  a  competitive 
advantage because of our ability to timely deliver high-
quality  products  and  service  from  the  early  stages  of 
product  development  through  the  high-volume  com-
mercial use of our products. We strategically locate our 
research facilities and clean rooms, manufacturing oper-
ations  and  the  related  technical  and  customer  support 
teams  to  be  responsive  to  our  customers’  needs.  We 
believe our extensive research and development facilities, 
in close proximity to our customers, provide a competi-
tive advantage.

In fiscal 2011, we expanded our facilities at several loca-
tions  in  the  Asia  Pacific  region  to  further  enhance  our 
custo mer relationships. We completed construction of a 
new 56,000 square foot research, development and man-
ufacturing  facility  in  Oseong,  South  Korea.  We  believe 
this  facility  will  enhance  our  ability  to  support  our  cus-
tomers  as  South  Korea  is  home  to  some  of  the  largest 
manufacturers of memory devices in the world. We have 
also  expanded  manufacturing  capacity  in  Japan  and 
Singapore  to  support  continued  growth  in  customer 
demand and to respond more quickly to our customers’ 
needs in the Asia Pacific region.

Robust  Global  Supply  Chain:  We  believe  that  product 
and supply chain quality is critical to success in our busi-
ness.  Our  customers  demand  continuous  improvement 
in the performance of our products in terms of product 
quality and consistency. We strive to drive out variation in 
our products and processes 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  support  the  unique  industry  demands  for 
product  quality.  To  support  our  quality  initiative,  we 
practice the concepts of Six Sigma across our Company. 
Six Sigma is a systematic, data-driven approach and meth-
odology  for  improving  quality  by  reducing  variability. 
We believe our Six Sigma initiatives have contributed to 
significant,  sustained  improvement  in  productivity  in  

our operations. We also believe the key supplier award  
we  received  in  fiscal  2011  from  Intel  is  evidence  of  our 
commitment to providing our customers with high qual-
ity solutions.

We also believe that the depth and breadth of our global 
supply chain are critical to our success and the success 
of  our  customers.  We  believe  our  global  supply  chain 
differentiates  us  from  our  competitors.  We  now  have 
five slurry manufacturing plants worldwide and a global 
network of suppliers, which we believe positions us well 
to mitigate supply interruptions when unexpected events 
occur.  The  major  earthquake  and  resulting  tsunami  in 
Japan in March 2011 was a prime example of such unex-
pected  events,  in  which  our  global  supply  chain  capa-
bilities  enabled  us  to  proactively  address  the  needs  of 
our customers and suppliers to assist them through that 
difficult time. We believe that our ability to address our 
customers’ concerns with openness and speed reflects 
the strength of our customer relationships and their trust 
in us as a global supplier and business partner.

Leveraging 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.  Our  primary  focus,  in  this  regard,  
is  on  opportunities  in  precision  optics  and  electronic 
substrates.

Our  QED  subsidiary  continues  to  be  the  technology 
leader in deterministic finishing for the precision optics 
industry.  QED’s  polishing  and  metrology  technology 
enables  customers  to  replace  manual  processes  with 
automated  solutions  that  provide  more  precise  and 
repeatable results. Another focus of our ESF business is 
the  polishing  of  electronic  substrates,  including  silicon 
and silicon-carbide wafers. A key step in the production 
of  these  wafers  is  CMP,  which  is  utilized  to  ensure  the 
wafers meet the stringent specifications required by IC 
manufacturers.

Industry Trends

Semiconductor Industry
We  believe  the  semiconductor  industry  continues  to 
demonstrate  several  clear  trends:  the  semiconductor 
business is defined by cyclical growth; there is constant 
pressure  to  reduce  costs  while  advancing  technology; 
and, the customer base continued to consolidate.

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 

6

industry  growth  that  we  saw  during  fiscal  2010  contin-
ued through fiscal 2011, although at a slower pace. We 
began  to  see  some  softening  of  demand  within  the 
industry  during  the  second  half  of  fiscal  2011  that  we 
attribute  to  general  uncertainty  in  the  global  economy 
and a modest correction of IC device inventory. Overall 
industry growth in fiscal 2011 positively affected demand 
for our products as evidenced by the 7.4% growth in our 
fiscal  2011  revenue  from  CMP  consumables  products 
compared to fiscal 2010. We believe that semiconductor 
industry demand will grow over the long term based on 
increased  usage  of  IC  devices  in  existing  applications, 
as  well  as  an  expanding  range  of  new  uses  of  these 
devices.  This  trend  of  increased  usage  of  IC  devices  is 
most evident in the area of mobile connectivity, including 
devices  such  as  smart-phones  and  tablets.  However,  at 
present, there is uncertainty regarding macro-economic 
factors and the outlook for the global economy. There-
fore,  we  believe  the  near-term  outlook  for  the  semi- 
conductor industry is also uncertain. We believe that our 
Company is well positioned to operate successfully over 
a range of demand environments as we have successfully 
navigated our business through industry and macroeco-
nomic 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 
quality and performance attributes that can reduce their 
overall cost of ownership, pursue ways to use less CMP 
materials, and also aggressively pursue price reductions 
on the materials they buy. The pressure on manufacturers 
to  reduce  costs  has  led  a  number  of  integrated  device 
manufacturers  to  increase  their  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  companies  that  manufacture  semicon-
ductor devices continues to decline both through merg-
ers and acquisitions as well as through alliances among 
different  companies.  Smaller  manufacturers  may  not 
have the technology or resources necessary to compete 
with  the  larger  manufacturers  on  a  global  basis  as 
needed  in  the  market  today.  In  fiscal  2011,  we  saw  evi-
dence  of  this  in  the  memory  segment  of  the  industry. 
For  example,  prices  of  DRAM  chips  declined  signifi-
cantly during the second half of 2011 causing some of the 
smaller manufacturers to reduce their production since 
they  do  not  appear  to  be  able  to  operate  profitably  at 
prevailing  market  prices.  Some  larger  manufacturers 
have increased their production, and their market share, 

as they are able to produce at lower costs, yet still oper-
ate  profitably.  Additionally,  several  of  our  customers 
have  formed  consortia  and  research  and  development 
alliances to better manage the high cost of their devel-
opment  activities,  thus  reducing  the  number  of  design 
centers we serve.

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 revenue and 
net income for fiscal years 2010 and 2011 clearly demon-
strated these effects, improving dramatically from fiscal 
2009 as wafer starts grew following the severe downturn 
associated with the global economic recession of 2009. 
Growth  in  wafer  starts  in  fiscal  2011  was  more  modest 
than  in  fiscal  2010,  and  macroeconomic  uncertainty 
clouds  the  near-term  outlook  for  the  semiconductor 
industry.  Over  the  long  term,  we  anticipate  the  world-
wide  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  produced  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  manufacture  of  semiconductor  devices  that  will 
require CMP.

We expect the anticipated long-term growth in demand 
will  be  somewhat  mitigated  by  continued  increase  in 
efficiency 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 improvements in 
technology,  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 greater 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 
processes must be considered in developing CMP solu-
tions. As a result, we generally see customers selecting 
suppliers  earlier  in  their  development  processes  and 
maintaining  preferred  supplier  relationships  through 
production. Therefore, we believe that close  collabora-
tion with our customers offers the best opportunity for 
optimal  CMP  solutions.  We  also  believe  that  research 
and  development  programs  continue  to  be  vital  to  our 
success  as  we  develop  and  commercialize  innovative, 
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 emerg-
ing technologies. However, we believe we are well posi-
tioned  to  continue  our  leadership  in  CMP  slurries,  and 
to continue to grow our CMP pad business. We believe 
we  have  the  experience,  scale,  capabilities  and  infra-
structure  that  are  required  for  success,  and  we  work 
closely with the largest customers in the semiconductor 
industry to meet their growing expectations as a trusted 
business partner.

Our CMP slurry competitors range from small companies 
that  compete  with  a  single  product  and/or  in  a  single 
geographic region to divisions of global companies with 
multiple  lines  of  CMP  products  for  IC  manufacturers. 
However, we believe we have more CMP slurry business 
than any other provider. In our view, we are the only CMP 
slurry supplier today that serves a broad range of custom-
ers  by  offering  and  supporting  a  full  line  of  CMP  slurry 
solutions for all major applications over a range of tech-
nologies, and that has a proven track record of supplying 
these products globally in high volumes with the atten-
dant required high level of technical support services.

With respect to CMP polishing pads, a division of Dow 
Chemical  has  held  the  dominant  market  position  for  a 
number of years. We believe we are the second largest 
supplier  of  polishing  pads  in  the  world.  A  number  of 
other  companies  are  attempting  to  enter  this  market, 
providing  potentially  viable  product  alternatives.  We 
believe our pad materials and our continuous pad man-
ufacturing  process  have  enabled  us  to  produce  a  pad 
with a longer pad life, lower defectivity and greater con-
sistency  for  our  customers  than  traditional  offerings, 
thus  reducing  their  total  pad  cost.  We  believe  this  has 
fueled significant growth in sales of our pad products in 
recent years.

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 
advantage to customers in the precision optics industry, 
which still relies heavily on traditional artisanal 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.  Logic  customers 
often  outsource  some  or  all  of  the  production  of  their 
devices to foundries, which provide contract manufactur-
ing  services,  in  order  to  avoid  the  high  cost  of  process 

development,  constructing  and  operating  a  fab,  or  to 
provide additional capacity when needed.

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

We  use  a  highly  collaborative  approach  to  build  close 
relationships  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 commercial-
ization 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 interact closely with our custom-
ers,  using  our  research  and  development  facilities  and 
capabilities  to  design  CMP  products  tailored  to  their 
precise needs. Next, our applications engineers work with 
customers to integrate our products into their manufac-
turing  processes.  Finally,  as  part  of  our  sales  process, 
our logistics and sales personnel provide supply, ware-
housing 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 provides us an additional 
means to collaborate with our customers.

Our QED subsidiary supports customers in the semicon-
ductor equipment, aerospace, defense, security, research, 
biomedical and consumer imaging markets. QED counts 
among its worldwide customers leading precision optics 
manufacturers,  major  semiconductor  original  equip-
ment  manufacturers,  research  institutions,  and  the 
United States government and its contractors.

In  fiscal  2011,  our  five  largest  customers  accounted  for 
approximately  47%  of  our  revenue,  with  TSMC  and 
Samsung accounting for approximately 17% and 10% of 
our revenue, respectively. For additional information on 
concentration 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  and  ESF  businesses,  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 technology leader. 
We  develop  and  formulate  new  and  enhanced  CMP 
solutions  tailored  to  our  customers’  requirements.  We 
work  closely  with  our  customers  at  their  facilities  to 
identify  their  specific  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	our	CMP	products	in	our	custom-
ers’ manufacturing facilities, including the application 
of  Six  Sigma  as  a  tool  to  reduce  variation  and  drive 
process improvements; 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 criteria 
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  provide  acceptable  system  economics  for 
our  customers.  As  dimensions  become  smaller  and  as 
materials  and  designs  increase  in  complexity,  these 
challenges require significant investments in R&D.

We also commit internal R&D resources to our ESF busi-
ness. We believe that application areas we are currently 
developing,  such  as  precision  optics  and  electronic 

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  quality  of  these  wafers 
and reduce the customers’ total cost of ownership.

We believe that a competitive advantage can be gained 
through  technology,  and  that  our  investments  in  R&D 
provide us with polishing and metrology capabilities that 
support  the  most  advanced  and  challenging  customer 
technology requirements on a global basis. In fiscal 2011, 
2010 and 2009, we incurred approximately $58.0 million, 
$51.8  million  and  $48.2  million,  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  depreci-
ated over their useful lives.

Our  global  R&D  team  includes  experts  from  the  semi-
conductor  industry  and  scientists  from  key  disciplines 
required for the development of high-performance CMP 
consumable  products.  We  operate  an  R&D  facility  in 
Aurora,  Illinois,  that  features  a  Class  1  clean  room  and 
advanced equipment for product development, includ-
ing 300mm polishing and metrology capabilities; a tech-
nology  center  in  Japan,  which  includes  a  Class  1  clean 
room with 300mm polishing, metrology and slurry devel-
opment  capability;  an  R&D  facility  in  Taiwan  within  our 
Epoch subsidiary that includes a clean room with 200mm 
polishing  capability;  a  new  R&D  facility  in  South  Korea 
that  was  opened  in  August  2011;  an  R&D  laboratory  in 
Singapore that provides slurry formulation capability for 
the  data  storage  industry;  and  a  research  facility  in 
Rochester,  New  York  to  support  our  QED  business.  All 
of  these  facilities  underscore  our  commitment  both  to 
continuing  to  invest  in  our  technology  infrastructure  to 
maintain  our  technology  leadership,  and  to  becoming 
even more responsive to the needs of our customers.

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 in the 
interest  of  supply  assurance  and  to  control  costs.  For 
additional  information  regarding  these  agreements, 
refer to “Tabular Disclosure of Contractual 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, 2011, we had 210 
active U.S. patents and 78 pending U.S. patent applica-
tions.  In  most  cases  we  file  counterpart  foreign  patent 
applications. Many of these patents are important to our 
continued development of new and innovative products 
for CMP and related processes, as well as for new busi-
nesses. Our patents have a range of duration and we do 
not expect to lose any material patent through expiration 
in the next four years. We attempt to protect our intel-
lectual property rights through a combination of patent, 
trademark,  copyright  and  trade  secret  laws,  as  well  as 
employee and third-party nondisclosure and assignment 
agreements.  We  vigorously  and  proactively  pursue 
 parties that attempt to compromise our investments in 
research and development by infringing our intellectual 
property.  For  example,  from  2007  to  2011,  we  were 
involved  in  a  legal  action  against  DuPont  Air  Products 
NanoMaterials  LLC  (DA  Nano),  a  competitor  of  ours, 
regarding whether certain specific formulations of slurry 
products  used  for  tungsten  CMP  infringe  certain  CMP 
slurry patents that we own, and the validity of those and 
other  of  our  patents.  All  of  our  patents  at  issue  in  the 
case were found valid, but the specific products at issue 
were found to not infringe the asserted claims of these 
patents.  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 portfo-
lio. These enhancements may be via licenses or assign-
ments or we may acquire certain proprietary technology 
and  intellectual  property  when  we  make  acquisitions, 
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 opportu-
nities 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 emissions, 
wastewater  discharges,  the  handling  and  disposal  of 
solid and hazardous wastes, and occupational safety and 
health.  We  believe  that  our  facilities  are  in  substantial 
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,  Europe  and  Taiwan  are  ISO  14001  certified, 

10

which requires that we implement and operate according 
to various procedures that demonstrate our dedication 
to waste reduction, energy conservation and other envi-
ronmental  concerns.  We  are  committed  to  maintaining 
these certifications and are actively pursuing 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  expenditures  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 compli-
ance 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, 
2011,  we  employed  1,025  individuals,  including  558  in 
operations, 242 in research and development and tech-
nical, 101 in sales and marketing and 124 in administra-
tion.  None  of  our  employees  are  covered  by  collective 
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, 
see  Note  19  of  “Notes  to  the  Consolidated  Financial 
Statements” included in Item 8 of Part II of this Form 10-K.

Available Information
Our annual reports on Form 10-K, quarterly reports on 
Form  10-Q,  definitive  proxy  statements  on  Form  14A, 
current  reports  on  Form  8-K,  and  any  amendments  to 
those reports are made available free of charge on our 
Company website, www.cabotcmp.com, as soon as rea-
sonably practicable after such reports are filed with the 
Securities and Exchange Commission (SEC). Statements

tion that we file electronically with the SEC.

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, 
2010.  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  primarily  dependent  upon 
semiconductor  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. 
For  example,  the  semiconductor  industry  grew  signifi-
cantly during the past two years following a severe eco-
nomic downturn, and generally, overall demand for our 
products  has  followed  this  same  cycle.  However,  we 
began to see some softening of demand in the second 
half  of  fiscal  2011.  Some  industry  analysts  predict  this 
softening  may  continue  through  the  first  half  of  fiscal 
2012. In addition, our business has experienced histori-
cal  seasonal  trends  as  evidenced  by  a  decrease  in  our 
revenue  in  the  second  quarter  of  fiscal  2011  from  the 
revenue  recorded  in  the  first  quarter  of  2011,  and  an 
increase  in  revenue  in  the  third  quarter  of  fiscal  2011. 
Our limited visibility to future customer orders makes it 
difficult  for  us  to  predict  industry  trends.  If  the  global 
economy  weakens  further  and/or  the  semiconductor 
industry  weakens,  whether  in  general  or  as  a  result  of 
specific factors, such as the current European sovereign 
debt crisis, the March 2011 natural disasters in Japan, or 
the November 2011 flooding in Thailand, that have had 
effects  on  the  semiconductor,  data  storage  and  infor-
mation  technology  industries,  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. For instance, we may 
experience  negative  impacts  on  cash  flows  due  to  the 
inability of our customers to pay their obligations to us 
or our production process may be harmed if our suppli-
ers  cannot  fulfill  their  obligations  to  us.  We  may  also 
have to reduce the carrying value of goodwill and other 
intangible  assets,  which  could  harm  our  financial  posi-
tion and results of operations.

Some  additional  factors  that  affect  demand  for  our 
products  include:  the  types  of  products  that  our  cus-
tomers  may  produce,  such  as  logic  devices  versus 
 memory devices; the various technology nodes at which 
those  products  are  manufactured;  customers’  specific 
manufacturing  process  integration  schemes;  the  short 
order  to  delivery  time  for  our  products;  quarter-to- 
quarter  changes  in  customer  order  patterns;  market 
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 
changes  and  advances  in  the  design,  manufacture, 
 performance  and  application  of  IC  devices,  and  our 
 customers  continually  pursue  lower  cost  of  ownership 
and higher performance of materials consumed in their 
manufacturing  processes,  including  CMP  slurries  and 
pads, as a means to reduce the costs and increase the 
yield  in  their  manufacturing  facilities.  We  expect  these 
technological  changes  and  advances,  and  this  drive 
toward  lower  costs  and  higher  yields,  will  continue  in  
the  future.  Potential  technology  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  important  to  the  IC  device  manufac-
turing 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  CMP  consumables  customer  base  is  concentrated 
among a limited number of large customers. The num-
ber of semiconductor manufacturers has declined both 
through  mergers  and  acquisitions  as  well  as  through 
strategic  alliances.  Industry  analysts  predict  that  this 
trend  will  continue,  which  means  the  semiconductor 
industry  will  be  comprised  of  fewer  and  larger  partici-
pants if their prediction is correct. One or more of these 
principal  customers  could  stop  buying  CMP  consum-
ables from us or could substantially reduce the quantity 

11

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 
 significant number of smaller customers, could seriously 
harm  our  business,  financial  condition  and  results  of 
operations.

In  fiscal  2011,  our  five  largest  customers  accounted  for 
approximately  47%  of  our  revenue,  with  Taiwan  Semi-
conductor Manufacturing Company (TSMC) and Samsung 
accounting  for  approximately  17%  and  10%,  respec-
tively, of our revenue. In fiscal year 2010, our five largest 
customers accounted for approximately 48% of our rev-
enue, with TSMC and United Microelectronics Corporation 
accounting for approximately 18% and 11%, respectively. 
Samsung accounted for less than 10% of our revenue in 
fiscal 2010.

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 interrup-
tion 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  inter-
ruption that may occur during production or delivery of 
our products, such as weather-related problems or natu-
ral  disasters,  such  as  the  March  2011  earthquakes  and 
tsunami in Japan. Consistent with our initial assessment 
in our second fiscal quarter of 2011, these natural disasters 
have not had a significant impact on the semiconductor 

12

industry,  or  on  our  business  or  supply  chain,  although 
Japan was the only geographic region in which our busi-
ness  did  not  grow  in  fiscal  2011.  Yet,  it  still  is  unclear 
what  long-term  effects  these  disasters  may  have  on 
Japan’s economy and on the global economic environ-
ment as Japan represents the world’s third largest econ-
omy. Our supply chain may also be negatively impacted 
by  unanticipated  price  increases  due  to  supply  restric-
tions  beyond  the  control  of  our  Company  or  our  raw 
material suppliers.

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 us and our customers. In addi-
tion, 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%,  86% 
and 84% of our revenue was generated by sales to cus-
tomers  outside  of  the  United  States  for  the  fiscal  2011, 
2010 and 2009, 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 also encounter the risks that we may 
not  be  able  to  repatriate  the  earnings  from  certain  of 
our foreign operations, derive the anticipated tax bene-
fits of our foreign operations or recover the investments 
made in our foreign operations.

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 technol-
ogies, assets and companies, either through acquisitions, 
investments  or  alliances,  in  order  to  supplement  our 
internal  growth  and  development  efforts.  Acquisitions 
and  investments,  such  as  our  fiscal  2009  acquisition  of 
Epoch  Material  Co.,  Ltd.,  a  Taiwan-based  company, 
involve numerous risks, including the following: difficul-
ties  and  risks  in  integrating  the  operations,  technolo-
gies,  products  and  personnel  of  acquired  companies; 
diversion of management’s attention  from  normal  daily 
operations  of  the  business;  increased  risk  associated 
with foreign operations; potential difficulties and risks in 
entering  markets  in  which  we  have  limited  or  no  direct 
prior experience and where competitors in such markets 
have  stronger  market  positions;  potential  difficulties  in 
operating new businesses with different business mod-
els;  potential  difficulties  with  regulatory  or  contract 
compliance  in  areas  in  which  we  have  limited  experi-
ence; initial dependence on unfamiliar supply chains or 
relatively small supply partners; insufficient revenues to 
offset  increased  expenses  associated  with  acquisitions; 
potential loss of key employees of the acquired compa-
nies; 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, asset acquisi-
tion or investments in other entities. Acquisitions by us 
could have negative effects on our results of operations, 
in  areas  such  as  contingent  liabilities,  gross  profit  mar-
gins,  amortization  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  or  assets  are  inher-
ently  risky  because  these  businesses  or  assets  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 invest-
ments  to  reflect  other  than  temporary  declines  in  their 
value,  which  could  harm  our  business  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 that could restrict our 
ability  to  market  our  existing  products  and/or  to  inno-
vate 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 failure 
to  obtain  or  maintain  adequate  protection  of  our  intel-
lectual property rights for any reason, including through 
the patent prosecution process or in the event of litiga-
tion  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 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 protect-
ing 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, 2011, which were classified as other long-
term  assets  on  our  Consolidated  Balance  Sheet.  If  cur-
rent  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 
 markets,  then  we  may  not  be  able  to  monetize  these 

13

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  conditions 
generally and specifically as they may impact participants 
in the semiconductor and related industries; changes in 
financial  estimates  and  recommendations  by  securities

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.

capacity  and  capacity  expansion  opportunities  and 
technological  capability  to  meet  our  current  and 
expected  demand  in  the  foreseeable  future.  In  fiscal 
2011,  we  increased  our  manufacturing  capacity  and 
added new capabilities in the Asia Pacific region includ-
ing  the  construction  of  a  new  research,  development 
and manufacturing facility in South Korea, and expanded 
manufacturing  capacity  in  our  Geino,  Japan  and 
Singapore facilities.

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, 
from 2007 to 2011, we were involved in a legal action in 
the  United  States  against  DuPont  Air  Products 
NanoMaterials LLC (DA Nano), a CMP slurry competitor, 
regarding whether certain specific formulations of slurry 
products  used  for  tungsten  CMP  infringe  certain  CMP 
slurry patents that we own, and the validity of those and 
other  of  our  patents.  All  of  the  Cabot  Microelectronics 
Corporation  patents  at  issue  in  the  case  were  found 
valid,  but  the  specific  products  at  issue  were  found  to 
not infringe the asserted claims of these patents.

In  January  2008,  our  Board  of  Directors  authorized  a 
share repurchase program for up to $75.0 million of our 
outstanding  common  stock.  We  repurchased  564,568 
shares for $25.0 million in fiscal 2011 under this program, 
which  was  completed  during  the  fiscal  quarter  ended 
March 31, 2011. In November 2010, our Board of Directors 
authorized  a  new  share  repurchase  program  for  up  to 
$125.0 million of our outstanding common stock, which 
became  effective  on  the  authorization  date.  We  repur-
chased 671,100 shares for $29.1 million during fiscal 2011 
under  this  new  program.  Share  repurchases  are  made 
from  time  to  time,  depending  on  market  conditions,  in 
open  market  transactions,  at  management’s  discretion. 
We  fund  share  purchases  under  these  programs  from 
our available cash balance.

Separate from this share repurchase program, a total of 
33,840 shares were purchased during fiscal 2011 pursu-
ant to the terms of our Second Amended and Restated 
Cabot  Microelectronics  Corporation  2000  Equity 
Incentive Plan (EIP) as shares withheld from award recipi-
ents  to  cover  payroll  taxes  on  the  vesting  of  shares  of 
restricted stock granted under the EIP.

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” 
(MD&A),  as  well  as  disclosures  included  elsewhere  in 
this  Form  10-K,  include  “forward-looking  statements” 
within  the  meaning  of  the  Private  Securities  Litigation 
Reform Act of 1995. This Act provides a safe harbor for 
forward-looking statements to encourage companies to 
provide  prospective  information  about  themselves  so 
long as they identify these statements as forward-looking 
and provide meaningful cautionary statements identify-
ing important factors that could cause actual results to 
differ  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  participates;  international  events,  regulatory 
or legislative activity, or various economic factors; prod-
uct performance; the generation, protection and acqui-
sition  of  intellectual  property,  and  litigation  related  to 
such  intellectual  property;  new  product  introductions; 
development  of  new  products,  technologies  and  mar-
kets;  the  acquisition  of  or  investment  in  other  entities; 
uses  and  investment  of  the  Company’s  cash  balance; 
the  construction  and  operation  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  expec-
tations  and  are  inherently  uncertain.  Our  actual  results 
may  differ  significantly  from  our  expectations.  We 
assume  no  obligation  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”)  supplies 
high-performance  polishing  slurries  and  pads  used  in 
the  manufacture  of  advanced  integrated  circuit  (IC) 
devices within the semiconductor industry, in a process 
called  chemical  mechanical  planarization  (CMP).  CMP 
polishes surfaces at an atomic level, thereby enabling IC 
device  manufacturers  to  produce  smaller,  faster  and 
more  complex  IC  devices  with  fewer  defects.  We 

operate  predominantly  in  one  industry  segment—the 
development,  manufacture  and  sale  of  CMP  consum-
ables.  We  develop,  produce  and  sell  CMP  slurries  for 
polishing many of the conducting and insulating materi-
als  used  in  IC  devices,  and  also  for  polishing  the  disk 
substrates and magnetic heads used in hard disk drives. 
We  also  develop,  manufacture  and  sell  CMP  polishing 
pads, which are used in conjunction with slurries in the 
CMP process. We also pursue other demanding surface 
modification  applications  through  our  Engineered 
Surface  Finishes  (ESF)  business  where  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  economic  and  industry  growth  that  we  saw  during 
fiscal 2010 in the overall semiconductor industry and for 
our Company continued into fiscal 2011. Unit growth in 
the semiconductor industry has been driven in particu-
lar  by  increased  demand  for  mobile  internet  products 
such  as  smart  phones  and  tablets.  However,  we  began 
to see a softening of demand within the semiconductor 
industry  in  the  second  half  of  fiscal  2011  based  on  cer-
tain  factors  including  general  uncertainty  in  the  global 
economy and a modest correction of IC inventory. Some 
industry  analysts  project  that  this  softening  of  demand 
may  continue  through  the  first  half  of  our  fiscal  2012. 
Consequently,  we  remain  cautious  regarding  demand 
trends in fiscal 2012. There are many factors that make it 
difficult  for  us  to  predict  future  revenue  trends  for  our 
business,  including  those  discussed  in  Part  I,  Item  1A 
entitled “Risk Factors” in this Form 10-K.

Our fiscal 2011 performance was highlighted by a number 
of strategic investments we made to further strengthen 
our  global  position  for  the  future.  We  completed  con-
struction of a new research, development and manufac-
turing  facility  in  South  Korea,  which  we  believe  will 
strengthen our ability to serve the second largest CMP 
market  in  the  world.  We  expanded  our  manufacturing 
facility in Japan to meet increased demand for our CMP 
slurry  products  and  we  expanded  our  manufacturing 
facility in Singapore to meet higher demand for our data 
storage products. We also developed and commercial-
ized innovative new products in all of our business areas 
to  address  traditional  CMP  applications  as  well  as  new 
and emerging technologies.

Revenue for fiscal 2011 was $445.4 million, which repre-
sented  an  increase  of  9.1%  from  the  $408.2  million 
reported  for  fiscal  2010,  and  was  a  record  level  for  our 
Company.  The  increase  in  revenue  from  fiscal  2010 
reflects increased sales volume primarily due to contin-
ued  growth  of  the  semiconductor  industry.  We  experi-
enced  revenue  growth  across  all  of  our  product  lines, 
including  each  of  our  slurry  areas,  our  polishing  pads 
business  and  our  ESF  business.  We  also  experienced 
revenue  growth  in  each  geographic  area  in  which  we 

20

operate,  except  in  Japan,  including  a  32%  increase  in 
revenue in South Korea.

Gross  profit  expressed  as  a  percentage  of  revenue  for 
fiscal 2011 was 48.1%, which represents a decrease from 
the 49.9% reported for fiscal 2010, but was within our full 
year  guidance  range  of  48%  to  50%  of  revenue.  The 
decrease in gross profit percentage from fiscal 2010 was 
primarily  due  to  higher  fixed  manufacturing  costs,  the 
negative effects of foreign exchange rate changes, par-
ticularly  with  respect  to  the  U.S.  dollar  against  the 
Japanese yen, which accounted for approximately a 1.5 
percentage point decrease in gross margin percentage, 
and  selective  price  decreases,  partially  offset  by  a 
higher-valued  product  mix.  We  expect  our  gross  profit 
percentage for full fiscal year 2012 to be in the range of 
46%  to  48%.  Our  fiscal  2012  guidance  reflects  antici-
pated  continued  adverse  impacts  of  foreign  exchange 
rate changes, fixed costs associated with our new facility 
in South Korea and uncertainty within the semiconduc-
tor industry and the global economy. However, we may 
experience fluctuations in our gross profit due to a num-
ber  of  factors,  including  the  extent  to  which  we  utilize 
our manufacturing capacity and changes in our product 
mix,  which  may  cause  our  quarterly  gross  profit  to  be 
above or below this range.

Operating  expenses  of  $133.7  million,  which  include 
research, development and technical, selling and market-
ing, and general and administrative expenses, increased 
3.3%, or $4.2 million, from the $129.5 million reported for 
fiscal  2010.  The  increase  was  primarily  due  to  higher 
staffing-related  costs  and  higher  expenses  for  clean 
room materials, partially offset by lower professional fees. 
In fiscal 2012, we expect our full year operating expenses 
to be in the range of $135 million to $140 million.

Diluted  earnings  per  share  of  $2.20  in  fiscal  2011 
increased  3.3%,  or  $0.07,  from  $2.13  reported  in  fiscal 
2010,  and  represented  a  record  level  for  our  Company. 
The  increase  was  primarily  due  to  increased  sales 
 volume, partially offset by a lower gross margin percent-
age,  higher  operating  expenses  and  a  higher  effective 
tax rate.

The  results  of  operations  for  the  fiscal  year  ended 
September  30,  2011  include  certain  adjustments  to 
 correct  prior  period  amounts,  which  we  have  deter-
mined  to  be  immaterial  to  the  current  period  and  the 
prior periods to which they relate. Adjustments in fiscal 
2011  listed  below,  the  first  four  of  which  were  made  in 
the first two quarters, are related to: (1) $1.5 million ($1.0 
million,  net  of  tax)  in  employer-paid  fringe  benefits  for 
required contributions to our 401(k) Plan, Supplemental 
Employee Retirement Plan, and non-United States statu-
tory  pension  plans  as  a  result  of  our  annual  payment 
pursuant to our fiscal 2010 annual incentive cash bonus 
program  (AIP);  (2)  income  tax  expense  of  $0.7  million 

recorded for certain compensation in fiscal 2008 through 
2010  for  which  a  previous  tax  benefit  should  not  have 
been recorded; (3) the reversal of a $0.5 million deferred 
tax  asset  regarding  certain  share-based  compensation 
expense  which  is  not  subject  to  such  tax  treatment;  
(4) our under accrual of $0.3 million ($0.2 million, net of 
tax) for payments made pursuant to the AIP as a result 
of the calculation of results against goals under the AIP; 
and  (5)  other  immaterial  corrections  to  deferred  tax 
assets  and  liabilities  that  reduced  our  income  tax 
expense by $0.1 million. Collectively, prior period adjust-
ments reduced net income in fiscal 2011 by $2.3 million 
and diluted earnings per share by approximately $0.10.

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  allowance 
for  doubtful  accounts  is  based  on  historical  collection 
experience,  adjusted  for  any  specific  known  conditions 
or  circumstances.  While  historical  experience  may 
 provide a reasonable estimate of uncollectible accounts, 
actual  results  may  differ  from  what  was  recorded.  In 
 fiscal  2009,  the  global  economic  recession  adversely 
affected  our  ability  to  collect  accounts  receivable  from 

21

some  of  our  customers.  The  recession  also  caused  a 
small number of our customers to file for bankruptcy 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  customers  and,  if 
global  economic  conditions  worsen,  we  may  have  to 
record additional increases to our allowances for doubt-
ful  accounts.  As  of  September  30,  2011,  our  allowance 
for  doubtful  accounts  represented  2.0%  of  gross 
accounts receivable. If we had increased our estimate of 
bad  debts  to  3.0%  of  gross  accounts  receivable,  our 
general  and  administrative  expenses  would  have 
increased by $0.5 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  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.  Should  actual 
 warranty  costs  differ  substantially  from  our  estimates, 
revisions  to  the  estimated  warranty  liability  may  be 
required. As of September 30, 2011, our warranty reserve 
represented  0.3%  of  the  current  quarter  revenue.  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 $1.0 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 marketabil-
ity 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,  2011  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,  2011,  we  owned  two  auction  rate 
securities (ARS) with an estimated fair value of $8.1 million 
($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. 
Historically,  these  periodic  auctions  provided  a  liquid 
market for these securities. General uncertainties in the 
global credit markets reduced liquidity in the ARS mar-
ket, and this illiquidity continues.

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 
 classification 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.  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 secu-
rity.  We  performed  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,  and  we  applied  a  risk  factor  to  reflect  current 
liquidity issues in the ARS market. Key inputs to our dis-
counted  cash  flow  model  include  projected  cash  flows 
from interest and principal payments and the weighted 
probabilities  of  improved  liquidity  or  debt  refinancing 
by the issuer. We also incorporate certain Level 2 market 
indices into the discounted cash flow analysis, including 
published rates such as the LIBOR rate, the LIBOR swap 
curve  and  a  municipal  swap  index  published  by  the 
Securities  Industry  and  Financial  Markets  Association. 
We  also  considered  the  probability  of  default  in  pay-
ment by the issuer of the securities, the strength of the 
insurance  backing  and  the  probability  of  failure  by  the 
insurance  carrier  in  the  case  of  default  by  the  issuer  of 
the  securities.  In  November  2011,  the  municipality  that 
issued our impaired ARS filed for bankruptcy protection. 
We considered these developments, in light of the con-
tinued  insurance  backing,  and  have  concluded  the 
impairment we have maintained remains adequate and 
temporary.  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 obli-
gations and the bond insurance 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 

22

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 measurement 
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 independent 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  recog-
nized  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  2011,  we 
recorded  $0.2  million  in  impairment  expense.  In  fiscal 
2010 and 2009, we recorded $0.2 million and $1.2 million 
in impairment expense, respectively.

We  evaluate  the  estimated  fair  value  of  investments 
annually  or  more  frequently  if  indicators  of  poten - 
tial  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 3 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 
Company’s  product  portfolio;  expected  costs  to 
develop  the  IPR&D  into  commercially  viable  products 
and estimated cash flows from the products when com-
pleted; and discount 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 inac-
curate,  and  unanticipated  events  and  circumstances 
may occur which may cause actual realized values to be 
different from management’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. 
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, 2011, the 
date of our annual impairment test. Initially, our Company 
had only one reporting unit as we were created from a 
division 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  historically  determined  the  fair  value  of  our 
reporting  units  using  a  discounted  cash  flow  analysis 
(“step one” analysis) of our projected future results. The 
step one analysis we performed in the fourth quarter of 
fiscal 2010 indicated the fair value of our reporting units was 
significantly higher than the carrying value. As discussed  

23

in  Notes  2  and  7  of  the  Notes  to  the  Consolidated 
Financial  Statements,  effective  September  30,  2011,  we 
adopted new accounting pronouncements related to our 
goodwill impairment analysis. The new accounting guid-
ance allows an entity to first assess qualitative factors to 
determine if it is more likely than not that the fair value 
of a reporting unit is less than its carrying amount (“step 
zero” analysis). In fiscal 2011, we used this new guidance 
in our annual impairment analysis for goodwill because 
our  cash  flows  for  all  of  our  reporting  units  exceeded 
the expectations we had as of September 30, 2010.

The recoverability of indefinite lived intangible assets is 
measured  using  the  royalty  savings  method.  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 
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 2011, we determined that  there  was  no impair-
ment  of  our  goodwill  and  intangible  assets  as  of 
September 30, 2011.

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 purchase plan 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 peri-
ods 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 purchase plan 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  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 meet the definition of retirement eligible pursuant 
to terms of their award agreements during the contrac-
tual 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 award.

Accounting for Income Taxes
Current income taxes are determined based on estimated 
taxes  payable  or  refundable  on  tax  returns  for  the  cur-
rent  year.  Deferred  income  taxes  are  determined  using 
enacted tax rates for the effect of temporary differences 
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  sustained  by  the  taxing 
authorities,  based  on  the  technical  merits  of  the  posi-
tion. In fiscal 2011 and 2010, we elected to permanently 
reinvest the earnings of certain of our foreign subsidiar-
ies outside the U.S. rather than repatriating the earnings 
to the U.S. See the section titled “Liquidity and Capital 
Resources” in this MD&A and Note 16 of the Notes to the 
Consolidated  Financial  Statements  for  additional  infor-
mation on income taxes and permanent reinvestment.

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 $445.4 million in fiscal 2011, which repre-
sented an increase of 9.1%, or $37.2 million, from fiscal 
2010. The increase in revenue was driven by a $35.6 mil-
lion increase in sales volume, a $5.5 million increase due 
to  the  effect  of  foreign  exchange  rate  changes,  and  a 
$4.7 million increase due to a higher-priced product mix. 
These  increases  were  partially  offset  by  an  $8.9  million 
decrease  in  revenue  due  to  a  lower  weighted-average 
selling  price  for  our  CMP  consumables.  The  economic 
and industry growth that we saw during fiscal 2010 con-
tinued into fiscal 2011. However, we saw some softening 
of demand in the semiconductor industry in the second 
half  of  fiscal  2011  based  on  certain  factors,  including 
general uncertainty in the global economy and a modest 
correction  of  integrated  circuit  (IC)  device  inventory. 
Some  industry  analysts  currently  project  this  softening 
of  demand  to  persist  through  the  first  half  of  our  fiscal 
2012, so we are cautious regarding future demand trends 
within the semiconductor industry.

Cost of Goods Sold
Total cost of goods sold was $231.3 million in fiscal 2011, 
which represented an increase of 13.0%, or $26.6 million, 
from fiscal 2010. The increase in cost of goods sold was 
primarily  due  to  $17.8  million  from  increased  sales  vol-
ume  due  to  the  increased  demand  for  our  products,  a 
$9.5 million increase due to the effect of foreign exchange 
rate changes, a $6.9 million increase due to higher fixed 
manufacturing costs, a $1.8 million increase due to higher 
freight and packaging costs, a $1.3 million increase due 
to certain production variances and a $0.7 million increase 
due  to  higher  sample  costs.  These  increases  were  par-
tially offset by an $11.5 million decrease in cost of goods 
sold due to 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,  a  number  of  factors 
could  impact  the  future  cost  of  raw  materials,  packag-
ing,  freight  and  labor.  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  48.1% 
in  fiscal  2011  as  compared  to  49.9%  for  fiscal  2010.  The 
decrease in gross profit as a percentage of revenue was 
primarily  due  to  higher  fixed  manufacturing  costs,  the 
negative effects of foreign exchange rate changes, selec-
tive  price  decreases  and  the  absence  of  a  raw  material 
supplier credit we recognized in the first quarter of fiscal 
2010 related to our achieving a certain volume threshold 
in  calendar  2009,  partially  offset  by  a  higher-valued 
product mix. We expect our gross profit percentage for 
full  fiscal  year  2012  to  be  in  the  range  of  46%  to  48%. 
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 changes 
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 
$58.0 million in fiscal 2011, which represented an increase 
of  12.0%,  or  $6.2  million,  from  fiscal  2010.  The  increase 
was primarily due to $3.6 million in higher staffing-related 
costs,  related  to  higher  staffing  levels  and  separation 
costs  related  to  the  transition  of  one  of  our  executive 
officers,  and  $2.2  million  in  higher  expenses  for  clean 
room materials.

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.

cussed  in  Note  10  of  the  Notes  to  the  Consolidated 
Financial Statements.

Provision for Income Taxes
Our  effective  income  tax  rate  was  34.5%  in  fiscal  2011 
compared  to  32.5%  in  fiscal  2010.  The  increase  in  the 
effective tax rate was primarily due to a number of factors 
related to share-based compensation expense, including 
tax impacts of stock option exercises and the vesting of 
restricted  stock  for  certain  employees,  and  taxable 
executive  compensation  in  excess  of  limits  defined  in 
section  162(m)  of  the  Internal  Revenue  Code,  partially 
offset  by  the  reinstatement  of  the  U.S.  research  and 
experimentation  tax  credit  in  December  2010,  which 
was  retroactively  effective  as  of  January  1,  2010.  As 
 discussed in the “Overview” section of this MD&A, our 
income tax provision in fiscal 2011 included adjustments 
to correct prior period amounts, including $0.7 million in 
tax expense related to executive compensation in fiscal 
2008  through  2010  for  which  a  previous  tax  benefit 
should  not  have  been  recorded,  and  the  reversal  of  a 
$0.5 million deferred tax asset related to certain share-
based compensation expense.

Selling and Marketing
Selling  and  marketing  expenses  were  $29.8  million  in 
 fiscal  2011,  which  represented  an  increase  of  10.7%,  or 
$2.9 million, from fiscal 2010. The increase was primarily 
due to $1.3 million in higher staffing-related costs, $0.6 
million  in  higher  travel-related  costs  and  $0.4  million  in 
higher miscellaneous selling expenses.

Net Income
Net income was $51.7 million in fiscal 2011, which repre-
sented  an  increase  of  4.5%,  or  $2.2  million,  from  fiscal 
2010. The increase was primarily due to increased sales 
volume, partially offset by a lower gross margin percent-
age,  increased  operating  expenses  and  a  higher  effec-
tive tax rate.

General and Administrative
General and administrative expenses were $45.9 million 
in fiscal 2011, which represented a decrease of 9.6%, or 
$4.9 million, from fiscal 2010. The decrease was primarily 
due to $6.8 million in lower professional fees, including 
costs to enforce our intellectual property, partially offset 
by  $1.1  million  in  higher  staffing-related  costs  and  $0.6 
million in higher depreciation expense. See Part I, Item 3 
entitled “Legal Proceedings” and Note 17 of the Notes 
to the Consolidated Financial Statements for more infor-
mation on the enforcement of our intellectual property.

Other Income (Expense), Net
Other expense was $1.5 million in fiscal 2011, compared 
to  $0.7  million  during  fiscal  2010.  The  increase  in  other 
expense  was  primarily  due  to  $1.1  million  in  foreign 
exchange  effects,  primarily  related  to  changes  in  the 
exchange rate of the Japanese yen and the New Taiwan 
dollar  to  the  U.S.  dollar,  net  of  the  gains  and  losses 

Year Ended September 30, 2010, Versus Year 
Ended September 30, 2009

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.

26

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.

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.

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 AIP, $0.6 million in 
higher  travel-related  costs,  and  $0.2  million  in  higher 
office  equipment  expenses,  partially  offset  by  the 
absence  of  $1.1  million  in  pre-tax  impairment  charges 
recorded  on  certain  research  and  development  equip-
ment during fiscal 2009.

Selling and Marketing
Selling  and  marketing  expenses  were  $26.9  million  in 
 fiscal  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, includ-
ing  costs  associated  with  our  AIP,  $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,  pri-
marily related to our AIP, $4.2 million in higher professional 

fees,  including  costs  to  enforce  our  intellectual  prop-
erty, 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 intellectual 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 fiscal 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,  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  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 compen-
sation.  Increases  in  the  effective  tax  rate  in  fiscal  2010 
that partially offset these decreases included decreases 
in tax-exempt interest income and the expiration of the 
research  and  experimentation  tax  credit  effective 
December 31, 2009, which was not retroactively reinstated 
for our fiscal 2010 until the first quarter of our fiscal 2011.

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.

Liquidity and Capital Resources
We had cash flows from operating activities of $93.6 mil-
lion  in  fiscal  2011,  $88.4  million  in  fiscal  2010  and  $44.7 
million  in  fiscal  2009.  Our  cash  provided  by  operating 
activities  in  fiscal  2011  originated  from  $51.7  million  in 
net  income,  $41.0  million  in  non-cash  items,  and  a  $0.9 
million  increase  in  cash  flow  due  to  a  net  decrease  in 
working capital. The increase in cash from operations in 
fiscal 2011 from fiscal 2010 was primarily due to increased 
net  income  and  deferred  tax  expense,  as  well  as 
decreased  accounts  receivable  in  fiscal  2011,  partially 
offset by an increase in working capital associated with 
higher  inventories  and  lower  accrued  expenses  and 
accounts payable. The decrease in accounts receivable 
was primarily due to improved cash collections in fiscal 
2011. The increase in inventories was primarily due to a 
general inventory build to meet the increased customer 
demand we experienced in fiscal 2011. The decrease in 
accrued  expenses  was  primarily  due  to  the  payment 
made in the first quarter of fiscal 2011 of our fiscal 2010 
annual  incentive  cash  bonus,  partially  offset  by  the 
accrual of our fiscal 2011 annual incentive cash bonus, 
which  we  expect  will  be  paid  in  the  first  quarter  of  
fiscal 2012.

We used $28.2 million in investing activities in fiscal 2011 
representing  $28.1  million  in  purchases  of  property, 
plant and equipment and $0.1 million in other investing 
cash outflows. Capital expenditures in fiscal 2011 included 
the  construction  of  our  new  facility  in  South  Korea  and 
capacity  expansions  of  our  Japan  and  Singapore  facili-
ties, net of the amounts that remain in accounts payable 
and  accrued  expenses  at  year  end.  We  used  $11.9  mil-
lion  in  investing  activities  in  fiscal  2010  representing 
$11.7 million in purchases of property, plant and equip-
ment  and  $0.2  million  in  other  investing  cash  outflows. 
We  used  $69.0  million  in  investing  activities  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. 
See Note 3 and Note 7 of the Notes to the Consolidated 
Financial  Statements  for  more  information  on  business 
combinations  and  intangible  assets.  We  estimate  that 
our  total  capital  expenditures  in  fiscal  2012  will  be 
between $25 million and $30 million.

In fiscal 2011, cash flows used in financing activities were 
$17.9 million. We used $54.1 million to repurchase com-
mon  stock  under  our  share  repurchase  program,  $1.4 
million  to  repurchase  common  stock  pursuant  to  the 
terms  of  our  Second  Amended  and  Restated  Cabot 
Microelectronics  Corporation  2000  Equity  Incentive 

Plan  (EIP)  for  shares  withheld  from  employees  to  cover 
payroll taxes on the vesting of restricted stock awarded 
under the EIP, and we made $1.3 million in principal pay-
ments  under  capital  lease  obligations.  These  cash  out-
flows were partially offset by $38.1 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 (ESPP). In addition, we received $0.8 mil-
lion  in  tax  benefits  related  to  stock  options  exercised 
and vesting of restricted stock awarded under our EIP. 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  EIP  for  shares  withheld  from  employees  and  pur-
chased  by  the  Company  to  cover  payroll  taxes  on  the 
vesting  of  restricted  stock  awarded  under  the  EIP,  and 
we made $1.2 million in principal payments under capi-
tal lease obligations. These cash outflows were partially 
offset by $3.4 million received from the issuance of com-
mon  stock  related  to  the  exercise  of  stock  options 
granted under our EIP and our ESPP. 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  ESPP.  These  cash  inflows  were 
partially  offset  by  $1.1  million  in  principal  payments  on 
capital  leases  and  $0.3  million  in  repurchases  of  com-
mon  stock  pursuant  to  the  terms  of  our  EIP  for  shares 
withheld  to  cover  payroll  taxes  on  the  vesting  of 
restricted stock awarded under the EIP.

In  January  2008,  our  Board  of  Directors  authorized  a 
share repurchase program for up to $75.0 million of our 
outstanding  common  stock.  We  repurchased  564,568 
shares for $25.0 million in fiscal 2011 under this program, 
which  was  completed  during  the  fiscal  quarter  ended 
March 31, 2011. We also repurchased 723,184 shares for 
$25.0  million  during  fiscal  2010  under  this  program.  In 
November  2010,  our  Board  of  Directors  authorized  a 
new  share  repurchase  program  for  up  to  $125.0  million 
of our outstanding common stock, which became effec-
tive on the authorization date. We repurchased 671,100 
shares for $29.1 million during fiscal 2011 under this new 
program.  Share  repurchases  are  made  from  time  to 
time, depending on market conditions, in open market 
transactions,  at  management’s  discretion.  We  fund 
share  purchases  under  these  programs  from  our  avail-

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 through October 
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  and  in  August  2011,  the  scheduled  termination 
date was extended another year through October 2013. 
Under this agreement, interest accrues on any outstand-
ing 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 of September 30, 2011, we had $302.5 million of cash 
and cash equivalents, $29.1 million of which was held at 
foreign  subsidiaries  in  Singapore  and  Taiwan  where  we 
have  made  a  current  election  to  permanently  reinvest 
the  earnings  rather  than  repatriate  the  earnings  to  the 
U.S.  If  we  choose  to  repatriate  these  earnings  in  the 
future  through  dividends  or  loans  to  the  U.S.  parent 
company,  the  earnings  could  become  subject  to  addi-
tional income tax expense.

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,  general  merger  and  acquisition 
activities,  and  share  repurchases  for  the  foreseeable 
future.  However,  we  plan  to  further  expand  our  busi-
ness; therefore, we may need to raise additional funds in 
the  future  through  equity  or  debt  financing,  strategic 
relationships  or  other  arrangements.  Depending  upon 
conditions  in  the  capital  and  credit  markets,  we  could 
encounter difficulty securing additional financing in the 
type or amount necessary to pursue these objectives.

Off-Balance Sheet Arrangements
At  September  30,  2011  and  2010,  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.

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,  our  former  parent  company 
which is not a related party, 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 
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. 
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  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 

29

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 obligations 
include an aggregate amount of $7.8 million of contrac-
tual  commitments  related  to  our  Cabot  Corporation 
agreements for fumed silica and fumed alumina.

Other Long-Term Liabilities
Other long-term liabilities at September 30, 2011 consist 
of  liabilities  related  to  our  Japan  retirement  allowance, 
which represents approximately $4.9 million, our liability 
for future payments to be made under our Cabot Micro-
elec tronics  Supplemental  Employee  Retirement  Plan 
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 
 foreign operations maintain their accounting records in 
their  local  currencies.  Consequently,  period  to  period 
comparability of results of operations is affected by fluc-
tuations  in  exchange  rates.  The  primary  currencies  to 
which we have exposure are the Japanese yen and the 
New Taiwan dollar. As noted in the Overview section of 
Management’s  Discussion  and  Analysis  of  Financial 
Condition and Results of Operations, the negative effects 
of  foreign  exchange  rate  changes,  primarily  related  to 
the  Japanese  yen,  accounted  for  an  approximate  1.5 
percentage  point  decline  in  our  gross  profit  margin  in 
fiscal  2011  compared  to  fiscal  2010.  From  time  to  time 

we  enter  into  forward  contracts  in  an  effort  to  manage 
foreign  currency  exchange  exposure  on  our  balance 
sheet.  However,  we  may  be  unable  to  hedge  these 
exposures  completely.  During  fiscal  2011,  we  recorded 
$5.5  million  in  foreign  currency  translation  gains  that  
are  included  in  other  comprehensive  income  on  our 
Consolidated  Balance  Sheet.  These  gains  primarily 
relate to the revaluation of assets and liabilities denomi-
nated in the Japanese yen and the New Taiwan dollar at 
period  end  exchange  rates.  Approximately  13%  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,  which  reduces  the  net  exposure  on  the 
Consolidated Statement of Income. 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
Over  the  past  24  months,  there  has  been  a  significant 
weakening  of  the  U.S.  dollar  against  the  Japanese  yen, 
which  has  had  some  negative  impact  on  our  results  of 
operations.  We  have  performed  a  sensitivity  analysis 
assuming a hypothetical additional 10% adverse move-
ment  in  foreign  exchange  rates.  As  of  September  30, 
2011, the analysis demonstrated that such market move-
ments 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,  2011,  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  significantly  reduced  liquidity  in 
the ARS market, and this illiquidity continues. 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,  2011  and  2010,  and  the  results  of  their 
operations  and  their  cash  flows  for  each  of  the  three 
years in the period ended September 30, 2011 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,  2011,  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 
 circumstances.  We  believe  that  our  audits  provide  a 
 reasonable 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 
statements  in  accordance  with  generally  accepted 
accounting  principles,  and  that  receipts  and  expendi-
tures  of  the  company  are  being  made  only  in  accor-
dance with authorizations of management and directors 
of  the  company;  and  (iii)  provide  reasonable  assurance 
regarding  prevention  or  timely  detection  of  unauthor-
ized  acquisition,  use,  or  disposition  of  the  company’s 
assets that could have a material effect on the financial 
statements.

Because of its inherent limitations, internal control over 
financial reporting may not prevent or detect 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.

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

1. Background and Basis of Presentation
Cabot Microelectronics Corporation (“Cabot Micro elec-
tronics”, “the Company”, “us”, “we” or “our”) supplies 
high-performance  polishing  slurries  and  pads  used  in 
the  manufacture  of  advanced  integrated  circuit  (IC) 
devices within the semiconductor industry, in a process 
called  chemical  mechanical  planarization  (CMP).  CMP 
polishes surfaces at an atomic level, thereby enabling IC 
device  manufacturers  to  produce  smaller,  faster  and 
more  complex  IC  devices  with  fewer  defects.  We 
develop,  produce  and  sell  CMP  slurries  for  polishing 
many of the conducting and insulating materials used in 
IC  devices,  and  also  for  polishing  the  disk  substrates 
and  magnetic  heads  used  in  hard  disk  drives.  We  also 
develop,  manufacture  and  sell  CMP  polishing  pads, 
which  are  used  in  conjunction  with  slurries  in  the  CMP 
process. We also pursue other demanding surface mod-
ification  applications  through  our  Engineered  Surface 
Finishes  (ESF)  business  where  we  believe  we  can  lever-
age our expertise in CMP consumables for the semicon-
ductor  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  Securities 
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. 

Results of Operations
The  results  of  operations  for  the  fiscal  year  ended 
September  30,  2011  include  certain  adjustments  to 
 correct  prior  period  amounts,  which  we  have  deter-
mined  to  be  immaterial  to  the  current  period  and  the 
prior periods to which they relate. Adjustments in fiscal 
2011  listed  below,  the  first  four  of  which  were  made  in 
the  first  two  quarters  of  the  fiscal  year,  related  to:  
(1) $1,474 ($1,014, net of tax) in employer-paid fringe ben-
efits  for  required  contributions  to  our  401(k)  Plan, 
Supplemental  Employee  Retirement  Plan,  and  non-
United States statutory pension plans as a result of our 
annual  payment  pursuant  to  our  fiscal  2010  annual 
incentive  cash  bonus  program  (AIP);  (2)  income  tax 
expense  of  $671  recorded  for  certain  compensation  in 
fiscal 2008 through 2010 for which a previous tax benefit 
should not have been recorded; (3) the reversal of a $497 
deferred  tax  asset  regarding  certain  share-based  com-
pensation  expense  which  is  not  subject  to  such  tax 
treatment; (4) our under-accrual of $290 ($199, net of tax) 
for payments made pursuant to the AIP as a result of the 
calculation  of  results  against  goals  under  the  AIP;  and 

(5)  other  immaterial  corrections  to  deferred  tax  assets 
and  liabilities  that  reduced  our  income  tax  expense  by 
$101.  Collectively,  these  adjustments  reduced  net 
income  for  fiscal  2011  by  $2,280  and  diluted  earnings 
per share by approximately $0.10.

2. Summary of Significant Accounting Policies

Principles of Consolidation
The consolidated financial statements include the accounts 
of Cabot Microelectronics and its subsidiaries. All inter-
company  transactions  and  balances  between  the  com-
panies have been eliminated as of September 30, 2011.

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  contin-
gencies. We base our estimates on historical experience, 
current  conditions  and  on  various  other  assumptions 
that we believe are reasonable under the circumstances. 
However, future events are subject to change and esti-
mates  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, 2011 or 2010. 
See Note 4 for a more detailed discussion of other finan-
cial 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 resulting 
from  the  potential  inability  of  our  customers  to  make 

37

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 customers’ 
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  semiconductor 
industry  and  global  economy.  We  historically  have  not 
experienced material losses relating to accounts receiv-
able from individual customers or groups of customers.

Customers who represented more than 10% of revenue 
are as follows:

Taiwan Semiconductor  
  Manufacturing Co. (TSMC)
Samsung
United Microelectronics  
  Corporation (UMC)

TSMC  accounted  for  12.9%  and  13.6%  of  net  accounts 
receivable at September 30, 2011 and 2010, respectively. 
Samsung  accounted  for  11.4%  of  net  accounts  receiv-
able  at  September  30,  2011.  UMC  accounted  for  7.1% 
and  9.2%  of  net  accounts  receivable  at  September  30, 
2011 and 2010, respectively.

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 
inventory reserve is maintained based upon a historical 

percentage  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. We capital-
ize the costs related to the design and development of 
software used for internal purposes.

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  determined  to  be 
recoverable, but their useful lives are shorter than origi-
nally estimated, the net book value of the asset is depre-
ciated 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 

38

when  they  have  similar  economic  characteristics.  We 
had  three  reporting  units  to  which  we  allocated  good-
will  and  intangible  assets  as  of  September  30,  2011. 
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 
considered  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 report-
ing  unit  may  be  determined  using  a  discounted  cash 
flow analysis of our projected future results. As discussed 
later in this Note 2 under the heading “Effects of Recent 
Accounting  Pronouncements”,  an  entity  now  has  the 
option  to  assess  qualitative  factors  to  determine  if  the 
two-step impairment test must be performed. We elected 
this option in fiscal 2011 when we performed our annual 
impairment  review  of  goodwill.  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, 2011.

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 performance 
requirements. The warranty reserve is based upon a his-
torical  product  return  rate,  adjusted  for  any  specific 
known conditions or circumstances. Adjustments 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  and  New  Taiwan  dollar.  Our 
exposure  to  foreign  currency  exchange  risks  has  not 
been significant because a large portion of our business 
is denominated in U.S. dollars. However, there has been 
a  significant  weakening  of  the  U.S.  dollar  against  the 
Japanese  yen  over  the  past  24  months,  which  has  had 
some  negative  impact  on  our  results  of  operations.  As 
noted  in  the  Overview  section  of  Management’s 
Discussion  and  Analysis  of  Financial  Condition  and 
Results  of  Operations,  the  negative  effects  of  foreign 
exchange rate changes, primarily related to the Japanese 
yen, accounted for an approximate 1.5 percentage point 

decline  in  our  gross  profit  margin  in  fiscal  2011  com-
pared  to  fiscal  2010.  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 contracts do not qualify for hedge accounting 
under  the  accounting  rules  for  derivative  instruments. 
See Note 10 for a more detailed discussion of derivative 
financial 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  equip-
ment, all of which are part of the K.K., as well as for gen-
eral 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  trans-
actions. 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 comprehensive income.

We  also  maintain  intercompany  loan  agreements 
between some of our wholly-owned foreign subsidiaries, 
including  Cabot  Microelectronics  Singapore  Pte.  Ltd., 
Epoch  Material  Co.,  Ltd.  in  Taiwan  and  Hanguk  Cabot 
Microelectronics, LLC in South Korea. These loans pro-
vided  funds  for  the  construction  of  our  new  research, 
development and manufacturing facility in South Korea. 
These loans are also considered foreign currency trans-
actions  and  are  accounted  for  in  the  same  manner  as 
our intercompany loans to the K.K.

Purchase Commitments
We have entered into unconditional purchase obligations, 
which  include  noncancelable  purchase  commitments 
and take-or-pay arrangements with suppliers. We review 
our  agreements  and  make  an  assessment  of  the  likeli-
hood  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 

39

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  and  customer  acceptance.  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 estimated 
taxes  payable  or  refundable  on  tax  returns  for  the  cur-
rent  year.  Deferred  income  taxes  are  determined  using 
enacted tax rates for the effect of temporary  differences 
between the book and tax bases of recorded assets and 
liabilities.  The  effect  on  deferred  tax  assets  and  liabili-
ties 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  sustained  by  the  taxing 
authorities,  based  on  the  technical  merits  of  the  posi-
tion. In fiscal 2011 and 2010, we elected to permanently 
reinvest the earnings of certain of our foreign subsidiar-
ies outside the U.S. rather than repatriating the earnings 
to  the  U.S.  See  Note  16  for  additional  information  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 purchase plan 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  his-
torical 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 
purchase plan 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  assump-
tions 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.

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

For  additional  information  regarding  our  share-based 
compensation plans, refer to Note 12.

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
In October 2010, we adopted new accounting standards 
regarding the recognition of a controlling financial inter-
est in a variable interest entity (VIE). The primary benefi-
ciary of a VIE is defined as the enterprise that has both: 
1)  the  power  to  direct  the  activities  of  a  VIE  that  most 
significantly impact the entity’s economic performance; 
and 2) the obligation to absorb losses of the entity that 

40

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 
primary beneficiary of a VIE. The adoption of these new 
standards  did  not  have  any  impact  on  our  results  of 
operations, financial position or cash flows as we do not 
currently  have  any  interest  or  arrangements  that  are 
considered variable interest entities.

In October 2010, we adopted new accounting standards 
regarding the recognition of revenue for multiple deliv-
erable revenue arrangements. The new standards modify 
the fair value requirements regarding the recognition of 
revenue  under  multiple  deliverable  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 sell-
ing  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 cannot be determined. In addi-
tion,  the  residual  method  of  allocating  arrangement 
consideration  is  no  longer  permitted.  The  adoption  of 
these  new  standards  did  not  have  a  material  effect  on 
our results of operations, financial position or cash flows.

In October 2010, we adopted new accounting standards 
regarding  revenue  arrangements  that  include  software 
elements. The guidance in these new standards modifies 
the existing accounting rules regarding the recognition 
of revenue from the sale of software to exclude: (a) non-
software components of tangible products; and (b) soft-
ware  components  of  tangible  products  that  are  sold, 
licensed or leased with tangible products when the soft-
ware components and non-software components of the 
tangible product function together to deliver the tangi-
ble  product’s  essential  functionality.  The  adoption  of 
these  new  standards  did  not  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 
 disclosures. 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 measure-
ments.  ASU  2010-06  clarifies  the  disclosures  an  entity 
must  make  regarding  inputs  and  valuation  techniques 
used in fair value measurements. The ASU also clarifies 
that an entity should provide fair value disclosures 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 disclosures about the 
reconciliation of Level 3 measurements which are effec-
tive 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. 
Based  on  our  current  Level  3  fair  value  measurements, 
we believe that the adoption of the provisions related to 
Level 3 measurements will not have a material impact on 
the disclosures in our financial statements.

In May 2011, the FASB issued ASU No. 2011-04, “Fair Value 
Measurement  (Topic  820)—Amendments  to  Achieve 
Common  Fair  Value  Measurement  and  Disclosure 
Requirements  in  U.S.  GAAP  and  IFRSs”  (ASU  2011-04). 
The  amendments  in  ASU  2011-04  change  some  of  the 
wording  used  to  describe  certain  U.S.  GAAP  require-
ments  for  measuring  fair  value  and  disclosing  informa-
tion  about  fair  value  measurements.  Some  of  the 
amendments clarify the FASB’s intent about the applica-
tion  of  existing  fair  value  measurement  requirements 
and other amendments change a particular principle or 
requirement  for  measuring  fair  value  or  for  disclosing 
information about fair value measurements. ASU 2011-04 
is  effective  for  interim  and  annual  periods  beginning 
after December 15, 2011. We believe that the adoption 
of  ASU  2011-04  will  not  have  a  material  impact  on  the 
fair value measurements and their related disclosures in 
our financial statements.

In  June  2011,  the  FASB  issued  ASU  No.  2011-05, 
 “Com pre hensive  Income  (Topic  220)—Presentation  of 
Comprehensive  Income”  (ASU  2011-05).  The  provisions 
of ASU 2011-05 require an entity to present the total of 
comprehensive income, the components of net income, 
and  the  components  of  other  comprehensive  income 
either in a single continuous statement of comprehensive 
income or in two separate but consecutive statements. 
If two separate statements are presented, the statement 
of other comprehensive income should immediately fol-
low the statement of net income. ASU 2011-05 is effective 
for  fiscal  years,  and  interim  periods  within  those  years, 
beginning  after  December  15,  2011.  Early  adoption  of 
these provisions is permitted and will be applied retro-
spectively. The adoption of ASU 2011-05 will change the 
way  we  present  comprehensive  income  as  current  U.S. 
GAAP  permits  an  annual  presentation  of  comprehen-
sive income within the statement of equity and quarterly 
presentation  of comprehensive  income  within  the foot-
notes to the financial statements. We expect to present 
comprehensive income in a separate statement immedi-
ately  following  the  statement  of  net  income  beginning 
in our fiscal quarter ending March 31, 2012.

September  2011,  the  FASB  issued  ASU  No.  2011-08, 
“Intangibles-Goodwill  and  Other  (Topic  350)—Testing 
Goodwill for Impairment” (ASU 2011-08). The provisions 
of ASU 2011-08 provide an entity with the option to assess 
qualitative  factors  to  determine  whether  the  existence 
of  events  or  circumstances  leads  to  the  determination 
that  it  is  more-likely-than-not  that  the  fair  value  of  a 

41

reporting unit is less than its carrying amount. This qual-
itative  assessment  is  referred  to  as  a  “step  zero” 
approach. If, based on the review of the qualitative fac-
tors,  an  entity  determines  it  is  not  more-likely-than-not 
that the fair value of a reporting unit is less than its car-
rying value, the entity may skip the two-step impairment 
test required by prior accounting guidance. If an entity 
determines otherwise, the first step (“step one”) of the 
two-step impairment test is required. This new account-
ing guidance also gives the entity the option to bypass 
“step zero” and proceed directly to “step one”; an entity 
may resume performing “step zero”  in  any  subsequent 
period.  ASU  2011-08  is  effective  for  fiscal  years  begin-
ning  after  December  15,  2011,  with  early  adoption  per-
mitted  if  the  financial  statements  for  the  most  recent 
annual  or  interim  period  have  not  yet  been  issued.  We 
have chosen to early adopt these new accounting provi-
sions effective with our goodwill impairment review dur-
ing  the  fourth  quarter  of  fiscal  2011.  We  determined, 
based upon our qualitative assessment, that “step one” 
was  not  required  as  there  were  no  indications  that  the 
fair value of our reporting units was less than the carry-
ing value. See Note 7 for a more detailed discussion of 
our goodwill and intangible assets.

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, 
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 2011 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

assets  acquired;  depreciation  of  property,  plant  and 
equipment acquired; and, income taxes.

4. Fair Value of Financial Instruments
On October 1, 2009, we adopted the accounting provi-
sions that relate to the fair value of non-financial assets 
and non-financial liabilities. We did not elect the fair value 
options for any non-financial assets or non-financial lia-
bilities that were not previously required to be measured 
at fair value under other generally accepted accounting 
principles.  The  adoption  of  these  provisions  did  not 
have  a  material  impact  on  our  results  of  operations, 
financial position or cash flows.

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 inac-
tive  market,  or  other  observable  inputs.  Level  3  inputs 
consist of valuations based on unobservable inputs that 
are supported by little or no market activity.

The following tables present financial assets that we meas-
ured at fair value on a recurring basis at September 30, 
2011  and  2010.  As  permitted  under  the  relevant  stan-
dards, we have chosen to not measure any of our liabili-
ties at fair value as we believe our liabilities approximate 
their  fair  value  due  to  their  short-term,  highly  liquid 
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 ARS and other long-term 
investments  are  included  in  other  long-term  assets  on 
our  Consolidated  Balance  Sheet.  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  comprised  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.  Our  other 
long-term investments represent the fair value of invest-
ments under the Cabot Microelectronics Supplemental 
Employee  Retirement  Plan  (SERP),  which  is  a  nonquali-
fied  supplemental  savings  plan.  The  fair  value  of  the 
investments  is  determined  through  quoted  market 
prices  within  actively  traded  markets.  Although  the 
investments are allocated to individual participants and 
investment  decisions  are  made  solely  by  those  partici-
pants, the SERP has been deemed a nonqualified plan. 
Consequently,  the  Company  owns  the  assets  and  the 
related  liability  for  disbursement  until  such  time  a  par-
ticipant makes a qualifying withdrawal, and should have 
recorded  the  assets  and  liability  in  our  Consolidated 
Balance  Sheet  in  prior  periods.  As  a  result,  during  the 
quarter  ended  March  31,  2011,  we  established  a  long-
term  asset  of  $952  representing  the  fair  value  of  SERP 
investments  held  at  March  31  and  a  corresponding 
 liability  of  $952  in  other  long-term  liabilities  on  our 
Consolidated  Balance  Sheet.  The  long-term  asset  and 
long-term  liability  were  adjusted  to  $827  in  the  fourth 
quarter  of  fiscal  2011  to  reflect  their  fair  value  as  of 
September 30, 2011.

We applied accounting standards regarding the classifi-
cation and valuation of financial instruments to the valu-
ation  of  our  investment  in  ARS  at  September  30,  2011 
and  2010.  Our  ARS  investments  at  September  30,  2011 
consisted  of  two  tax  exempt  municipal  debt  securities 
with a total par value of $8,275. The ARS market began 
to experience illiquidity 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  holdings  continues  to  be  received  on 
scheduled interest payment dates. Our ARS, when pur-
chased, were generally issued by A-rated municipalities. 
Although  the  credit  ratings  of  both  municipalities  have 
been downgraded since our original investment, the ARS 
are  credit  enhanced  with  bond  insurance  and  currently 
carry a credit rating of AA+ by Standard and Poors.

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 of the insurance backing. Key inputs 
to  our  discounted  cash  flow  model  include  projected

$22,310  for  the  years  ended  September  30,  2011,  2010 
and 2009, 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 2011 and 2010 was 
not material.

7. Goodwill and Other Intangible Assets
Goodwill  was  $41,148  and  $40,436  as  of  September  30, 
2011  and  2010,  respectively.  The  increase  in  goodwill 
was  due  to  foreign  exchange  fluctuations  of  the  New 
Taiwan dollar.

cash flows from interest and principal payments and the 
weighted  probabilities  of  improved  liquidity  or  debt 
refinancing  by  the  issuer.  We  also  incorporate  certain 
Level  2  market  indices  into  the  discounted  cash  flow 
analysis,  including  published  rates  such  as  the  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  2011  for  fair  value 
measurements using level 3 inputs:

Balance as of September 30, 2010

$ 8,066

$ 8,041

Based on our fair value assessment, we determined that 
one ARS continues to be impaired as of September 30, 
2011.  This  security  has  a  fair  value  of  $3,091  (par  value 
$3,325). 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  previously 
recorded.  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 successfully monetized at par value $25 of this secu-
rity during our fiscal quarter ended March 31, 2011 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 determined that 
the  fair  value  of  the  other  ARS  was  not  impaired  as  of 
September 30, 2011. In November 2011, the municipality 
that  issued  our  impaired  ARS  filed  for  bankruptcy  pro-
tection. We considered these developments, in light of 
the  continued  insurance  backing,  and  have  concluded 
the  impairment  we  have  maintained  remains  adequate 
and  temporary.  See  Note  8  for  more  information  on 
these investments.

In fiscal 2011, other intangible assets increased by $275 
due to foreign exchange fluctuations of the New Taiwan 
dollar. In fiscal 2010, we acquired $515 in other intangible 
assets and other intangible assets increased by $323 due 
to foreign exchange fluctuations of the New Taiwan dollar.

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 (“step one”) of our 
projected  future  results.  As  discussed  in  Note  2  under 
the heading “Effects of Recent Accounting Pronounce-
ments”, effective September 30, 2011, we adopted new 
accounting  pronouncements  related  to  our  goodwill 
impairment analysis, which allows an entity to perform a 
“step zero” assessment of the fair value of their report-
ing  units.  In  the  fourth  quarter  of  fiscal  2011,  we  used 
this new guidance in our annual impairment analysis for 
goodwill. The recoverability of indefinite lived intangible 
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 impairment analy-
sis  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 2011, we determined that  there  was  no impair-
ment  of  our  goodwill  and  intangible  assets  as  of 
September 30, 2011.

Amortization expense was $2,720, $2,426 and $2,522 for 
fiscal 2011, 2010 and 2009, respectively. Estimated future 
amortization expense for the five succeeding fiscal years 
is as follows:

As discussed in Note 4 of this Form 10-K, the two ARS 
that  we  owned  as  of  September  30,  2011  are  classified 
as  long-term  investments.  The  securities  are  credit 
enhanced  with  bond  insurance  to  an  AA+  credit  rating 
and all interest payments continue to be received on a 
timely  basis.  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 maintain a $234 pretax reduction ($151 net of 
tax)  in  fair  value  on  one  of  the  ARS  that  we  had  first 
 recognized  in  fiscal  2008.  We  continue  to  believe  this 
decline in fair value is temporary based on: (1) the nature 
of  the  underlying  debt;  (2)  the  presence  of  bond  insur-
ance;  (3)  the  fact  that  all  interest  payments  have  been

ARS  during  the  quarter  ended  March  31,  2011;  and  
(5) 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.

As discussed in Note 4 of this Form 10-K, we recorded a 
long-term asset and a corresponding long-term liability 
of  $827  representing  the  fair  value  of  our  SERP  invest-
ments as of September 30, 2011.

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
Deferred revenue and  
  customer advances
Warranty accrual
Taxes, other than income taxes
Acquisition related

The  decrease  in  accrued  compensation  was  primarily 
due  to  the  payment  of  our  AIP  earned  in  fiscal  2010, 
 partially offset by the accrual of our AIP related to fiscal 
2011.  The  increase  in  deferred  revenue  and  customer 
advances  was  due  to  the  timing  of  customer  advances 
and  revenue  not  yet  earned  in  our  Engineered  Surface 
Finishes business.

10. Derivative Financial Instruments
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 deriv-
atives,  whether  designated  in  hedging  relationships  or 
not, are required to be recorded on the balance sheet at 
fair  value.  At  September  30,  2011,  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  associ-
ated with a net transactional exposure in Japanese Yen.

The fair value of our derivative instrument included in the Consolidated Balance Sheet, which was determined using 
Level 1 inputs, 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, the agree-
ment extends through October 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, and in August 2011, the 
scheduled termination date was extended another year 
through  October  2013.  Under  this  agreement,  interest 
accrues on any outstanding balance at either the lend-
ing 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 cor-
porate  purposes,  including  financing  working  capital, 
capital expenditures and acquisitions. The credit agree-
ment  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 Corpo-
ra tion 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 management with 
the  flexibility  to  attract,  retain  and  reward  our  employ-
ees, 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.  Beginning  in  March  2011,  non-qualified 
stock options granted to non-employee directors on an 
annual  basis  vest  100%  on  the  first  anniversary  of  the 
award date. Compensation expense related to our stock 
option awards was $6,871, $7,081 and $9,507 in fiscal 2011, 
2010  and  2009,  respectively.  For  additional  information 

on  our  accounting  for  share-based  compensation,  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. 
Beginning in March 2011, restricted stock units granted 
to non-employee directors on an annual basis vest 100% 
on  the  first  anniversary  of  the  award  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 stockholders, includ-
ing  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 
$5,184, $4,134 and $2,893 for fiscal 2011, 2010 and 2009, 
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. 
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

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  transferable. 
Because  employee  stock  options  and  employee  stock 
purchases  have  certain  characteristics  that  are  signif i-
cantly 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 accordance with appli-
cable accounting standards using an option-pricing model, 
those  values  may  not  be  indicative  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.

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  61,364,  38,050,  and  57,815  shares  were 
issued under the ESPP during fiscal 2011, 2010 and 2009, 
respectively.  Compensation  expense  related  to  the 
ESPP  was  $508,  $360  and  $324  in  fiscal  2011,  2010  and 
2009, 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  47,530  and  45,572  as  of  September 
30, 2011 and 2010, respectively. Compensation expense 
related  to  our  Directors’  Deferred  Compensation  Plan 
was  $83,  $68  and  $78  for  fiscal  2011,  2010  and  2009, 
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 purchase plan 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 peri-
ods 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 purchase 
plan 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. We estimate the 
expected volatility of our stock options based on a com-
bination  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 meet the definition of retirement eligible pursuant 
to their grants 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.

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 2011. The award agreements provide for 
immediate vesting of the award at the time of termina-
tion  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. Five of the Company’s non-employee 
directors had completed at least two full terms of  service 
as  of  the  date  of  the  March  2011  award.  Consequently, 
the  requisite  service  period  for  the  award  has  already 
been satisfied and we recorded the fair value of $1,010 
of  the  awards  to  these  five  directors  to  share-based 
com pensation  expense  in  the  fiscal  quarter  ended 
March  31,  2011  rather  than  recording  that  expense  
over  the  one-year  vesting  period  stated  in  the  award 
agreement.

deductions from options exercised was $4,401, $175 and 
$24 for fiscal 2011, 2010 and 2009, respectively. The total 
fair  value  of  stock  options  vested  during  fiscal  years 
2011,  2010  and  2009  was  $6,321,  $8,494  and  $12,560, 
respectively. As of September 30, 2011, there was $9,169 
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.

Restricted Stock
A summary of the  status of the restricted  stock awards 
and restricted stock unit awards outstanding under the 
EIP as of September 30, 2011, and changes during fiscal 
2011, are presented below:

to 60% of their eligible compensation. All amounts con-
tributed by participants and earnings on these contribu-
tions 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  compensation  that  is  con-
tributed, subject to limitations required by government 
regulations.  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  $4,201, 
$2,981 and $2,813 for the fiscal years ended September 
30, 2011, 2010 and 2009, respectively.

The  decrease  in  other  income  (expense)  in  fiscal  2011 
from  fiscal  2010  was  primarily  due  to  foreign  exchange 
effects,  primarily  related  to  changes  in  the  exchange 
rate of the Japanese yen and the New Taiwan dollar 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 
(expense)  in  fiscal  2010  from  fiscal  2009  was  primarily 
due to lower interest income resulting from lower inter-
est rates earned on our cash balances and investments 
compared  to  fiscal  2009,  and  the  foreign  exchange 
effects,  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.

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 
according to its terms.

Share Repurchases
In  January  2008,  our  Board  of  Directors  authorized  a 
share repurchase program for up to $75,000 of our out-
standing  common  stock.  We  repurchased  564,568 
shares  for  $25,000  in  fiscal  2011  under  this  program, 
which  was  completed  during  the  fiscal  quarter  ended 
March  31,  2011.  During  fiscal  2010,  we  repurchased 
723,184 shares of common stock under this program at  
a  cost  of  $24,998.  We  did  not  repurchase  any  shares  
under  the  share  repurchase  program  in  fiscal  2009.  In 
November  2010,  our  Board  of  Directors  authorized  a 
new share repurchase program for up to $125,000 of our 
outstanding common stock, which became effective on 
the  authorization  date.  We  repurchased  671,100  shares 
for  $29,105  during  fiscal  2011  under  this  new  program. 
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.  For  additional  information  on  share  repur-
chases,  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 
33,840, 24,651 and 14,425 shares were purchased during 
fiscal 2011, 2010 and 2009, respectively, pursuant to the 
terms  of  our  EIP  as  shares  withheld  from  award  recipi-
ents  to  cover  payroll  taxes  on  the  vesting  of  shares  of 
restricted stock granted under the EIP.

  Provision for income taxes

34.5% 32.5% 32.7%

In fiscal 2011 and 2010, we elected to permanently rein-
vest  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 approx-
imately  $25.5  million  of  undistributed  earnings  of  such 
subsidiaries. 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  by  3.0  and  2.7 
percentage points in fiscal 2011 and 2010, respectively.

The  increase  in  our  effective  tax  rate  in  fiscal  2011  was 
primarily  due  to  a  number  of  factors  related  to  share-
based compensation expense, including tax impacts of 
stock  option  exercises  and  the  vesting  of  restricted 
stock for certain employees, and taxable executive com-
pensation in excess of limits defined in section 162(m) of 
the  Internal  Revenue  Code.  As  discussed  in  footnote  1 
of this 10-K under the heading “Results of Operations”, 
income tax expense in fiscal 2011 included $671 related 
to  executive  compensation  in  fiscal  2008  through  2010 
and  a  $497  reversal  of  a  deferred  tax  asset  for  certain 
share-based compensation expense. These increases in 
our  effective  tax  rate  were  partially  offset  by  the  rein-
statement of the U.S. research and experimentation tax 
credit in December 2010, which was retroactively effec-
tive as of January 1, 2010.

The  accounting  guidance  regarding  the  uncertainty  in 
income taxes prescribes a threshold for the financial state-
ment recognition 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 uncer-
tain tax position 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.

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 Consolidated 
Balance  Sheet  were  $19  and  $6  at  September  30,  2011 
and  2010,  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 2008 through 
2010.  We  believe  the  tax  periods  open  to  examination 
by U.S. state and local governments include fiscal years 
2007 through 2010 and the tax periods open to exami-
nation  by  foreign  jurisdictions  include  fiscal  years  2004 
through 2010. 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:

Deferred tax assets:
  Employee benefits

Inventory

  Depreciation and amortization
  Product warranty
  Bad debt reserve
  Share-based compensation expense

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, 
from  2007  to  2011,  we  were  involved  in  a  legal  action 
against  DuPont  Air  Products  NanoMaterials  LLC  (DA 
Nano), a CMP slurry competitor, regarding whether cer-
tain  specific  formulations  of  slurry  products  used  for 
tungsten  CMP  infringe  certain  CMP  slurry  patents  that 
we own, and the validity of those and other of our pat-
ents. All of the Cabot Microelectronics Corporation pat-
ents  at  issue  in  the  case  were  found  valid,  but  the 
specific products at issue were found to not infringe the 
asserted claims of these patents.

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 during fiscal 2011 as follows:

Balance as of September 30, 2010
Reserve for product warranty during  

the reporting period
Settlement of warranty

Balance as of September 30, 2011

$  375

$  384

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, 
2011,  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 six years 
from  now  and  may  be  renewed  by  us.  Lease  commit-
ments 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 2011, 2010 and 2009 totaled $2,934, $2,480 
and $1,883, 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 
December  2006,  but  it  was  renewed  for  another  five-
year term ending in December 2011.

able leases as of September 30, 2011 are as follows:

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 business 
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.  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 meet-
ing minimum forecasted purchase volume requirements. 
We also operate under a fumed alumina supply agree-
ment  with  Cabot  Corporation  which  runs  through 
December  2011,  under  which  we  are  obligated  to  pay 
certain  fixed,  capital  and  variable  costs,  which  are  no 
longer  material  to  our  business.  Purchase  obligations 
include  $7,755  of  contractual  commitments  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 numerator 
and  denominator  of  the  basic  and  diluted  earnings  per  share  computations.  Basic  and  diluted  earnings  per  share 
were calculated as follows:

Numerator:

Net Income

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, 2011, 2010, and 2009, approximately 1.3 million, 2.6 million and 3.9 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.

not  meet  customers’  specifications  and  performance  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.  Additions  and  deductions  to  the  warranty  reserve  are  recorded  in  cost  of  goods  sold.  Charges  to

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 Sponsoring 
Organizations  of  the  Treadway  Commission  in  Internal 
Control—Integrated Framework. Management acknowl-
edges,  however,  that  all  internal  control  systems,  no 
matter how well designed, have inherent limitations and 
can  provide  only  reasonable  assurance  with  respect  to 
financial  statement  preparation  and  presentation.  In 
addition, the Company’s independent registered 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  auditors  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, 2011. Based on that evaluation, our CEO 
and CFO have concluded that our disclosure controls and 
procedures  were  effective  to  ensure  that  information 
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 accumulated 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 
main taining  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 
reporting  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  mainte-
nance  of  records  that  in  reasonable  detail  accurately 
and fairly reflect our transactions and dispositions of the 
Company’s  assets;  provide  reasonable  assurance  that 
transactions  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 unauthor-
ized  acquisition,  use  or  disposition  of  Company  assets 
that could have a material effect on our financial state-
ments would be prevented or detected on a timely basis. 
Because of its inherent limitations, internal control over 
financial reporting may not prevent or detect misstate-
ments. Also, projections of any evaluation of effectiveness 
to future periods are subject to the risk that controls may 
become  inadequate  because  of  changes  in  conditions, 
or  that  the  degree  of  compliance  with  the  policies  or 
procedures may deteriorate.

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 
evalu ation,  our  management  concluded  that  the  Com-
pany’s  internal  control  over  financial  reporting  was 
effective  as  of  September  30,  2011.  The  effectiveness  
of the Company’s internal control over financial report-
ing  as  of  September  30,  2011  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 reasonably 
likely to materially affect, our internal control over finan-
cial 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 limitations 
include the realities that judgments in decision-making 
can  be  faulty,  and  that  breakdowns  can  occur  because 
of  a  simple  error  or  mistake.  Additionally,  controls  can 
be circumvented by the individual acts of some persons, 
by collusion of two or more people or by management 
override  of  the  controls.  The  design  of  any  system  of 

59

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.

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.
