Message
from the PreSIDeNt AND ceo

Dear Fellow ShareholDerS:
FINANCIAL STRENGTH  At this time last year, our industry and economy had just begun to emerge from one of the most 
challenging periods in decades. The decisive actions and cost reduction initiatives we implemented enabled us to improve our 
profitability, while maintaining our focus on growing revenue throughout the year. Our achievement of record financial results 
in 2010 underscores the continued and successful execution of our profitable growth model as we emerged from the 2009 
downturn a stronger company with expanded growth opportunities. These accomplishments were further highlighted by 
our 20th consecutive year of profitability and the seventh consecutive quarter of sequential revenue growth from the low 
point of the business cycle in the first quarter of 2009 through the fourth quarter of 2010. These consistent results have 
produced significant value for Diodes and our shareholders, and we plan to continue to execute on this proven strategy.

For the full year of 2010, revenue reached a record $613 million, increasing 41% over the $434 million reported in 2009. 
Gross  profit  was  a  record  $225  million,  increasing  $104  million  or  86%  from  2009.  Gross  margin  increased  880  basis 
points  to  36.7%  due  to  benefits  from  our  high-operational  performance  and  utilization  at  our  wafer  fabs  as  well  as  to 
record  output  at  our  packaging  facilities,  cost  reduction  initiatives,  and  favorable  product  mix,  in  part  due  to  our  new 
product  initiatives.  GAAP  net  income  was  a  record  $77  million,  or  $1.68  per  diluted  share,  compared  to  $0.17  in  2009.  
Non-GAAP  adjusted  net  income1  was  a  record  $83  million  or  $1.82  per  share.  For  the  year,  cash  flow  from  operations 
amounted  to  $118  million,  net  cash  flow  was  $29  million  and  free  cash  flow1,  including  nearly  $90  million  in  capital 
equipment investment was $29 million, contributing to a year-end cash balance of $271 million. Our solid balance sheet 
positions the Company for continued growth and expansion opportunities in the future.

DIVERSIFICATION Most notable during the year, we announced our entry into the standard logic market and secured our 
first design wins. The logic market represents a natural fit for Diodes’ strategic focus on high-volume standard products and 
expands our total serviceable available market (SAM) to approximately $29 billion. Furthermore, the logic business has strong 
packaging synergies with our existing analog and discrete product lines, and we are able to utilize our own cost-effective 
high-volume assembly facilities that are well-suited for manufacturing low-pin count packages. We are pleased with our 
early  success  in  leveraging  this  capability  to  provide  customers  with  an  alternate  source  of  quality  high-performance 
logic products. We believe that our entry into the logic market will be a strong growth driver for years to come.

INNOVATION During the year, we continued to invest in new product development and achieved a high level of design wins 
that  contributed  to  increased  market  share  at  new  and  existing  customers.  Both  Diodes-  and  Zetex-branded  products 

reached record sales levels during the year. In 2010, we launched many new products across our analog, logic and discrete 
product families, including DIODESTAR™, our platform for a new line of high-voltage rectifiers. This proprietary process 
platform  was  developed  at  our  wafer  fabrication  facility  in  Oldham,  U.K.  and  draws  upon  our  expertise  in  both  bipolar 
transistors and MOSFET semiconductor technologies. With the release of our first device, we launched our DIODESTAR™ 
process which will support a wide range of products that meet the Energy Star® requirements for a variety of end applications, 
including LCD-LED televisions, printers, notebooks and desktop computers.

Global design activity in 2010 reached record levels across a broad range of product lines and end equipment. Our new 
family of MOSFET devices has been designed into every model being produced by the major LCD-LED television manufac-
turers for 2011. There was also significant design activity for our products in the portable consumer electronics market 
with major SBR® design wins in handheld media players, tablet computers and smartphones, as well as strong Hall-effect 
sensor adoption in the cell phone and notebook PC markets.

EXPANSION Our continued focus on expanding our product offerings has further strengthened our position with customers 
as a trusted and reliable supplier. Demand for our products remained strong throughout the year across all geographies, 
driven in part by the continued ramp-up of design wins and customer acceptance of our new product portfolio. In addition, 
the capital investments that we made to expand capacity at our packaging facilities enabled us to achieve record output 
and have positioned us well for the coming year. To support our customers and future expansion, we also announced in 
the third quarter of 2010 an investment agreement with the Management Committee of the Chengdu Hi-Tech Industrial 
Development Zone to establish a manufacturing facility in Chengdu, China. This multi-year project will serve as Diodes’ 
next assembly site once we have reached maximum production capacity at our Shanghai facilities in the coming years.

POSITIONED FOR CONTINUED SUCCESS In summary, I would like to emphasize that our consistent execution and record 
results demonstrate the scalability and sustainability of Diodes’ business model as well as the success of our profitable 
growth strategy. This approach has enabled Diodes to achieve better than market growth rates, and we plan to continue to 
execute on this strategy in the years to come. Looking forward, our future growth will be driven by securing greater market 
share in key end-equipment, launching additional products in new markets and leveraging our broadened product portfolio 
to maintain a high level of design wins, including an increasing contribution from our newly released standard logic products. 
We believe that Diodes is well positioned for continued success as we capitalize on our growth momentum throughout 2011.

I would also like to take this time to thank you, our shareholders, customers, employees and suppliers, for your continued 
support  and  confidence  in  Diodes  Incorporated.  I  look  forward  to  reporting  on  the  Company’s  future  successes  as  we 
remain focused on achieving profitable growth and increasing value for our shareholders.

Sincerely,

DR. KEH-SHEW LU

President and Chief Executive Officer

Message
from the chAIrmAN

I  am  privileged  to  have  shared  in  another  year  of  success  for  Diodes  Incorporated.  As  Chairman  of  the  Company  since 
1993, I have witnessed a number of economic and business cycles, including the industry’s broader decline through much of 
2008 and 2009. Over this time period, Dr. Lu and his management team proactively implemented a number of initiatives that 
helped Diodes to successfully navigate through the downturn, while skillfully positioning the Company to benefit greatly 
from the economic recovery. These efforts culminated in record financial achievements for Diodes in 2010, including revenue, 
gross margin and net income.

Today,  the  Company  continues  to  execute  on  the  profitable  growth  strategy  that  has  proven  successful  for  Diodes  over 
many years. This strategy is supported by a focus on the consistent introduction of innovative new products and the prudent 
expansion of our manufacturing and packaging facilities. In addition to our financial successes, Diodes has also made signifi-
cant progress in many other endeavors, including our commitments to sustainability and environmental responsibility.

Over the past year, the Company expanded our family of LED backlighting drivers, collectively leveraging the products and 
technology that we acquired from Zetex along with our own internal innovation and processes. LED technology and power 
management  solutions  represent  significant  growth  opportunities  for  Diodes  and  are  also  examples  of  the  Company 
doing its part to be part of energy efficient solutions that extend to its customers and consumers.

As another example of an initiative aimed at supporting both future growth and environmental responsibility, in September 
Diodes introduced a proprietary process platform for the manufacture of next generation high voltage rectifiers named 
DIODESTAR™. The process was designed to meet the requirements of new energy efficiency legislation as well as enable 
designers to comply with the stringent demands of the 80 PLUS Energy Star® requirements.

In conclusion, I would like to extend my personal gratitude to Dr. Lu for his admirable leadership and to the entire manage-
ment team for their dedication to the disciplined execution of Diodes’ business strategy, while simultaneously committing 
to environmental responsibility. I would also like to thank you, our shareholders, as well as our employees, customers 
and suppliers for your continued support, and I look forward to sharing our future success with you in 2011 and beyond.

Sincerely,

RAyMOND SOONG

Chairman of the Board

Business. 

GENERAL 

PART I 

We are a leading global manufacturer and supplier of high-quality, application specific standard products within the broad 
discrete,  logic  and  analog  semiconductor  markets,  serving  the  consumer  electronics,  computing,  communications,  industrial  and 
automotive  markets. These products include diodes, rectifiers, transistors, MOSFETs, protection devices, functional specific arrays, 
single  gate  logic,  amplifiers  and  comparators,  Hall-effect  and  temperature  sensors,  power  management  devices,  including  LED 
drivers,  DC-DC  switching  and  linear  voltage  regulators,  and  voltage  references  along  with  special  function  devices,  such  as  USB 
power  switches,  load  switches,  voltage  supervisors,  and  motor  controllers.  The  products  are  sold  primarily  throughout  Asia,  North 
America and Europe. 

  We design, manufacture and market these semiconductors for diverse end-use applications.  Semiconductors, which provide 
electronic  signal  amplification  and  switching  functions,  are  basic  building-block  electronic  components  that  are  incorporated  into 
almost  every  electronic  device.    We  believe  that  our  focus  on  standard  semiconductor  products  provides  us  with  a  meaningful 
competitive advantage relative to other semiconductor companies. 

Our  product  portfolio  addresses  the  design  needs  of  many  advanced  electronic  devices,  including  high-volume  consumer 
devices such as digital audio players, smartphones, tablets, notebook computers, flat-panel displays, mobile handsets, digital cameras 
and set-top boxes.  We believe that we have particular strength in designing innovative surface-mount semiconductors for applications 
with a critical need to minimize product size while maximizing power efficiency and overall performance, and at a lower cost than 
alternative  solutions.    Our  product  line  includes  over  nearly  7,000  products,  and  we  shipped  approximately  27.9 billion  units, 
19.0 billion  units,  and  18.5  billion  units  in  2010,  2009  and  2008,  respectively.  From  2005  to  2010,  our  net  sales  grew  from 
$214.8 million to $612.9 million, representing a compound annual growth rate of 23.3%.     

We serve approximately 235 direct customers worldwide, which consist of original equipment manufacturers (“OEM”) and 
electronic  manufacturing  services  (“EMS”)  providers.    Additionally,  we  have  approximately  55  distributor  customers  worldwide, 
through which we indirectly serve over 10,000 customers.   

We were incorporated in 1959 in California and reincorporated in Delaware in 1968. Our headquarters, logistics center, and 
Americas’ sales office are located in Dallas, Texas.  Our design, marketing and engineering centers are located in Dallas; San Jose, 
California; Taipei, Taiwan; Manchester, United Kingdom and Neuhaus, Germany.  We have a wafer fabrication facility located near 
Kansas City, Missouri and in Manchester; with two manufacturing facilities located in Shanghai, China, another in Neuhaus, and a 
fourth manufacturing facility being developed in Chengdu, China. Additional engineering, sales, warehouse and logistics offices are 
located in Taipei; Hong Kong; Manchester and Munich, Germany, with support offices located throughout the world.  

BUSINESS OUTLOOK 

For  2011  we  expect  to  see  continued  improvements  in  demand  and  order  rates  over  2010,  increased  production  ramps  of 
previous  design  wins  at  new  customers  and  the  introduction  of  new  product  applications  for  existing  customers.  We  expect  our 
business to continue to benefit from the increasing demand in China, as we consider the China market a major growth driver for our 
business.  We expect our manufacturing facilities  to maintain near full utilization, except in the first quarter of 2011 for our China 
operations where equipment utilization will be impacted by China labor shortages in the coastal region and fewer working days and 
the Chinese New Year Holiday in February.  Our strategy is to continue to enhance our position as a leading global manufacturer and 
supplier  of  high-quality  semiconductor  products,  and  to  continue  to  add  other  complementary  product  lines,  such  as  power 
management  and  logic  products,  using  our  packaging  technology  capability.    The  success  of  our  business  depends,  among  other 
factors, on the strength of the global economy and the stability of the financial markets, which in turn affect our customers’ demand 
for our products, the ability  of our customers to meet their payment obligations, the likelihood of customers canceling or deferring 
existing  orders  and  consumer  demand  for  items  containing  our  products  in  the  end-markets  we  serve.  We  believe  the  long-term 
outlook  for  our  business  remains  generally  favorable  despite  the  recent  volatility  in  the  global  economy  and  the  equity  and  credit 
markets as we continue to execute on the strategy that has proven successful for us over the years. Although the  current economy 
creates  a  more  challenging  environment  for  all  businesses,  we  believe  decisive  measures  taken  in  response  to  the  global  downturn 
have properly positioned us for our recent return to a profitable growth model and that over the long-term we are well positioned for 
future growth.  See “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Business Outlook” in 
Part II, Item 7 and “Risk Factors – The success of our business depends on the strength of the global economy and the stability of the 
financial markets, and any weaknesses in these areas may have a material adverse effect on our revenues, results of operations and 
financial condition.” in Part I, Item 1A of this Annual Report for additional information.

SEGMENT INFORMATION AND ENTERPRISE-WIDE DISCLOSURES 

For  financial  reporting  purposes,  we  operate  in  a  single  segment,  standard  semiconductor  products,  through  our  various 
design, manufacturing and distribution facilities. We sell product primarily through our operations in Asia, North America and Europe. 
We aggregate our products in a single segment because the products are similar and have similar economic characteristics, and the 
products  are  similar  in  production  process  and  share  the  same  customer  type.  See  Note  19  of  “Notes  to  Consolidated  Financial 
Statements” of this Annual Report for addition information. 

OUR INDUSTRY 

Semiconductors are critical components used in the manufacture of an increasing variety of electronic products and systems. 
Since the invention of the transistor in 1948, continuous improvements in semiconductor processes and design technologies have led 
to  smaller,  more  complex  and  more  reliable  devices  at  a  lower  cost  per  function.    The  availability  of  low-cost  semiconductors, 
together with increased customer demand for sophisticated electronic systems, has led to the proliferation of semiconductors in diverse 
end-use applications in the consumer electronics, computing, communications, industrial and automotive sectors.  These factors have 
also led to an increase in the total number of semiconductor components in individual electronic systems and an increase in the value 
of these components as a percentage of the total cost of the electronic systems in which they are incorporated. 

OUR COMPETITIVE STRENGTHS 

We believe our competitive strengths include the following: 

Flexible, scalable and cost-effective manufacturing – Our manufacturing operations are a core element of our success, and we 
have  designed  our  manufacturing  base  to  allow  us  to  respond  quickly  to  changes  in  demand  trends  in  the  end-markets  we  serve.  For 
example, we have structured our Shanghai assembly, test and packaging facilities to enable us to rapidly and efficiently add capacity 
and adjust product mix to meet shifts in customer demand and overall market trends.  As a result, for the past several years, except 
during  2009  when  we  saw  a  slowdown  in  global  economic  activity  and  a  decrease  in  global  demand  for  our  products,  we  have 
operated our Shanghai facilities at near full capacity, while at the same time significantly expanding that capacity.  Additionally, the 
Shanghai location of our manufacturing operations provides us with access to a workforce at a relatively low overall cost base while 
enabling us to better serve our leading customers, many of which are located in Asia.   

Integrated packaging expertise – We believe that we have particular expertise in designing and manufacturing innovative 
and proprietary packaging solutions that integrate multiple separate discrete elements into a single semiconductor product called an 
array.    Our  ability  to  design  and  manufacture  highly  integrated  semiconductor  solutions  provides  our  customers  with  products  of 
equivalent  functionality  with  fewer  individual  parts,  and  at  lower  overall  cost,  than  alternative  products.    This  combination  of 
integration,  functionality  and  miniaturization  makes  our  products  well  suited  for  high-volume  consumer  devices  such  as  LCD  and 
LED televisions and LCD panels, set-top boxes, consumer portables such as smartphones and tablets and notebooks. 

Broad customer base and diverse end-markets – Our customers are comprised of leading OEMs as well as leading EMS 
providers.    Overall,  we  serve  approximately  235  direct  customers  worldwide  and  over  10,000  additional  customers  through  our 
distributors. Our products are ultimately used in end-products in a number of markets served by our broad customer base, which we 
believe makes us less dependent on either specific customers or specific end-user applications.  

Customer  focused  product  development  –  Effective  collaboration  with  our  customers  and  a  high  degree  of  customer 
service  are  essential  elements  of  our  business.    We  believe  focusing  on  dependable  delivery  of  semiconductor  solutions  tailored  to 
specific end-user applications, has fostered deep customer relationships and created a key competitive advantage for us in the highly 
fragmented  discrete,  logic  and  analog  semiconductor  marketplace.    We  believe  our  close  relationships  with  our  customers  have 
provided us with deeper insight into our customers’ product needs.  This results in differentiation in our product designs and often 
provides us with insight into additional opportunities for new design wins in our customers’ products.  See “Risk Factors - We are and 
will continue to be under continuous pressure from our customers and competitors to reduce the price of our products, which could 
adversely affect our growth and profit margins” in Part I, Item 1A of this Annual Report for additional information. 

Management  experience  –  Two  members  of  our  executive  team  average  over  19  years  of  service  at  the  Company  and  the 
length  of  their  service  with  us  has  created  significant  institutional  insight  into  our  markets,  our  customers  and  our  operations.  
Additionally, the other six executive officers have an average of over 27 years experience in the semiconductor industry. 

In 2005, we appointed Dr. Keh-Shew Lu as President and Chief Executive Officer.  Dr. Lu has served as a director of Diodes 
since 2001 and has over 35 years of relevant industry experience.  Dr. Lu began his career at Texas Instruments, Inc. (“TI”) in 1974 
and  retired  in  2001  as  Senior  Vice  President  and  General  Manager  of  Worldwide  Analog,  Mixed-Signal  and  Logic  Products.    Our

Chief Financial Officer, Secretary and Treasurer, Richard White joined us in 2006 as our Senior Vice President of Finance until May, 
2009,  when  he  became  our  Chief  Financial  Officer.    Mr.  White  has  over  30  years  of  senior  level  finance  experience,  including  25 
years at TI.  Joseph Liu, Senior Vice President of Operations, joined us in 1990 and has over 35 years of relevant industry experience, 
having started his career in 1971 at TI.  Similarly, Mark King, Senior Vice President of Sales and Marketing, has been employed by us 
since  1991  and  has  over  25  years  of  relevant  industry  experience.    In  2006,  we  hired  Edmund  Tang,  Vice  President  of  Corporate 
Administration, who has over 30 years of managerial and engineering experience who came to us from FSI International Inc., a global 
supplier  of  wafer  cleaning  and  processing  technology  where  he  served  as  Asia  President  and  Francis  Tang,  Vice  President  of 
Worldwide Discrete Products, who has over 30 year of relevant industry experience.  In 2008, we hired Julie Holland, Vice President 
of Worldwide Analog Products, who came to us from TI with over 20 years of relevant industry experience and Colin Greene, Europe 
President and Vice President of Europe Sales and Marketing, joined us as a result of the acquisition of Zetex and brought with him 
over 20 years of relevant industry experience.   

OUR STRATEGY 

Our  strategy  is  to  continue  to  enhance  our  position  as  a  leading  global  designer,  manufacturer  and  supplier  of  high-quality 
application specific standard semiconductor products, and to continue to add other product lines, such as power management and logic 
products, using our packaging technology capability. 

The principal elements of our strategy include the following: 

Continue to rapidly introduce innovative discrete, logic and analog semiconductor products – We intend to maintain our 
rapid pace of new product introductions, especially for high-volume, growth applications with short design cycles, such as LCD and 
LED televisions and LCD panels, set-top boxes, consumer portables such as smartphones and tables and notebooks and other consumer 
electronics  and  computing  devices.    During  2010,  we  achieved  many  new  design  wins  at  OEMs.  Although  a  design  win  from  a 
customer does not necessarily guarantee future sales to that customer, we believe that continued introduction of new and differentiated 
product  solutions  is  critically  important  in  maintaining  and  extending  our  market  share  in  the  highly  competitive  semiconductor 
marketplace.  See “Risk Factors – Obsolete inventories as a result of changes in demand for our products and change in life cycles of our 
products could adversely affect our business, results of operations and financial condition.” in Part I, Item 1A of this Annual Report for 
additional information. 

Expand  our  available  market  opportunities  –  We  intend  to  aggressively  maximize  our  opportunities  in  the  standard 
semiconductor market as well as in related markets where we can apply our semiconductor design and manufacturing expertise.  A 
key  element  of  this  is  leveraging  our  highly  integrated  packaging  expertise  through  our  Application  Specific  Multi-Chip  Circuit 
(“ASMCC”)  product  platform,  which  consists  of  standard  arrays,  function  specific  arrays  and  end-equipment  specific  arrays.  We 
intend to achieve this by: 

(cid:190)  Continuing  to  focus  on  increasing  packaging  integration,  particularly  with  our  existing  standard  array  and  customer-specific 
array products, in order to achieve products with increased circuit density, reduced component count and lower overall product 
cost; 

(cid:190)  Expanding existing products and developing new products in our function specific array lines, which combine multiple discrete 

semiconductor components to achieve specific common electronic device functionality at a low cost; and 

(cid:190)  Developing new product lines, which we refer to as end-equipment specific arrays, which combine discrete components with 

logic and/or standard analog circuits to provide system-level solutions for high-volume, high-growth applications. 

Maintain  intense  customer  focus  –  We  intend  to  strengthen  and  deepen  our  customer  relationships.  We  believe  that 
continued focus on customer service is important and will help to increase our net sales, operating performance and overall market 
share. To accomplish this, we intend to continue to closely collaborate with our customers to design products that meet their specific 
needs.  A  critical  element  of  this  strategy  is  to  continue  to  further  reduce  our  design  cycle  time  in  order  to  quickly  provide  our 
customers with innovative products. Additionally, to support our customer-focused strategy, we historically expanded our sales force 
and field application engineers, particularly in Asia and Europe, during periods of growth.  

Enhance  cost  competitiveness  –  A  key  element  of  our  success  is  our  overall  low-cost  base.    While  we  believe  that  our 
Shanghai  manufacturing  facilities  are  among  the  most  efficient  in  the  industry,  we  will  continue  to  refine  our  proprietary 
manufacturing  processes  and  technology  to  achieve  additional  cost  efficiencies.    Historically,  except  during  2009  when  we  saw  a 
slowdown  in  global  economic  activity  and  a  decrease  in  global  demand  for  our  products,  we  have  operated  our  facilities  at  high 
utilization rates and increased product yields, in order to achieve meaningful economies of scale.

Pursue selective strategic acquisitions – As part of our strategy to expand our standard semiconductor product offerings and 
to  maximize  our  market  opportunities,  we  may  acquire  discrete,  logic,  analog  or  mixed-signal  technologies,  product  lines  or 
companies in order to enhance our standard and new product offerings.    

In June 2008, we completed the acquisition of Zetex, a then publicly traded U.K. semiconductor company and a leading provider 
of discrete and high performance analog semiconductor products for signal processing and power management.  Zetex designs and 
manufactures a broad range of standard and application focused linear integrated circuits and discrete semiconductor products using a 
wide variety of wafer processing technologies.  Through the acquisition of Zetex, we acquired a wafer fabrication plant in the U.K. 
and a package development, assembly and test facility in Germany.  In addition, we acquired sales offices in Munich and New York, 
which  are  supported  by  a  global  network  of  distributors  and  manufacturer's  representatives.  See  Note  2  of  “Notes  to  Consolidated 
Financial  Statements”  and  “Risk  Factors  –  Part  of  our  growth  strategy  involves  identifying  and  acquiring  companies  with 
complementary  product  lines  or  customers.  We  may  be  unable  to  identify  suitable  acquisition  candidates  or  consummate  desired 
acquisitions  and,  if  we  do  make  any  acquisitions,  we  may  be  unable  to  successfully  integrate  any  acquired  companies  with  our 
operations, which could adversely affect our business, results of operations and financial condition” in Part I, Item 1A of this Annual 
Report for additional information. 

CONVERTIBLE SENIOR NOTES 

On October 12, 2006, we issued and sold convertible senior notes with an aggregate principal amount of $230 million due 2026 
(the “Notes”), which pay 2.25% interest per annum on the principal amount of the Notes, payable semi-annually in arrears on April 1 and 
October 1 of each year, beginning on April 1, 2007.  As of December 31, 2010, we have repurchased a total of $95.7 million principal 
amount of Notes.  See Notes 1 and 10 of “Notes to Consolidated Financial Statements” of this Annual Report for additional information. 

OUR PRODUCTS  

Our product portfolio includes nearly 7,000 products that are designed for use in high-volume consumer devices such as LCD 
and LED televisions and LCD panels, set-top boxes, consumer portables such as smartphones and tablets and notebooks.  We target and 
serve end-equipment market segments that we believe have higher growth rates than other end-market segments served by the overall 
semiconductor industry. 

Our broad product line includes: 

(cid:190)  Discrete semiconductor products, including performance Schottky rectifiers; performance Schottky diodes; Zener diodes and 
performance Zener diodes, including tight tolerance and low operating current types; standard, fast, super-fast and ultra-fast 
recovery  rectifiers;  bridge  rectifiers;  switching  diodes;  small  signal  bipolar  transistors;  prebiased  transistors;  MOSFETs; 
thyristor surge protection devices; and transient voltage suppressors; 

(cid:190)  Complex  high-density  diode, transistor  and  mixed  technology  arrays,  in multi-pin  ultra-miniature  surface-mount  packages, 

including customer specific and function specific arrays; 

(cid:190)  Analog products, including power management devices and Hall-effect sensors;  

(cid:190)  Standard logic products, including open drain inverters; and

PRODUCT PACKAGING 

Our  device  packaging  technology  primarily  includes  a  wide  variety  of  surface-mount  packages.    Our  focus  on  the 
development  of  smaller,  more  thermally  efficient,  and  increasingly  integrated  packaging,  is  a  critical  component  of  our  product 
development.   We  provide  a comprehensive  offering of  miniature  and sub-miniature  packaging,  enabling us  to fit  components  into 
smaller  and  more  efficient  packages,  while  maintaining  the  same  device  functionality  and  power  handling  capabilities.    Smaller 
packaging  provides  a  reduction  in  the  height,  weight  and  board  space  required  for  our  components,  and  is  well  suited  for  battery-
powered, hand-held and wireless consumer applications and high-volume consumer devices such as LCD and LED televisions and LCD 
panels, set-top boxes, consumer portables such as smartphones and tablets and notebooks. 

CUSTOMERS 

We serve approximately 235 direct customers worldwide, which consist of OEMs and EMS providers. Additionally, we have 
approximately 55 distributor customers worldwide, through which we indirectly serve over 10,000 customers.  Our customers include:

We generally warrant that products sold to our customers will, at the time of shipment, be free from defects in workmanship 
and materials and conform to our approved specifications.  Subject to certain exceptions, our standard warranty extends for a period of 
one year from the date of shipment.  Warranty expense has not been significant. Generally, our customers may cancel orders on short 
notice without incurring a penalty. 

Many of our customers are based in Asia or have manufacturing facilities in Asia. Net sales by country consists of sales to 
customers in that country based on the country to which products are billed. For the year ended December 31, 2010, 30.6%, 23.1%, 
22.0%,  10.9%  and  13.4%  of  our  net  sales  were  derived  from  China,  Taiwan,  the  U.S.,  Europe  and  all  other  markets,  respectively, 
compared  to  30.4%,  28.2%,  17.3%,  11.3%  and  12.8%  in  2009,  respectively.    We  anticipate  the  percentage  of  net  sales  shipped  to 
customers in Asia to increase as the trend towards manufacturing in Asia continues.   

SALES AND MARKETING 

We market and sell our products worldwide through a combination of direct sales and marketing personnel, independent sales 
representatives and distributors.  We have direct sales personnel in the U.S., United Kingdom, France, Germany, Taiwan and China.  
We  also  have  independent  sales  representatives  in  the  U.S.,  Japan,  Korea,  and  Europe.  We  currently  have  distributors  in  the  U.S.,

MANUFACTURING OPERATIONS AND FACILITIES 

We operate two manufacturing facilities located in Shanghai, China, one in Neuhaus, Germany and are developing a fourth 
facility  in  Chengdu,  China.    Our  wafer  fabrication  facilities  are  located  near  Kansas  City,  Missouri  and  near  Manchester,  United 
Kingdom. Our facilities in Shanghai and Neuhaus perform packaging, assembly and testing functions, our facility being developed in 
Chengdu will perform packaging, assembly and testing functions, our Kansas City facility is a 5-inch and 6-inch wafer foundry and 
our Manchester facility is a 6-inch wafer foundry.  

During 2010, we announced an investment agreement with the Management Committee of the Chengdu Hi-Tech Industrial 
Development Zone (the “CDHT”).  Under this agreement, we have agreed to form a joint venture with a Chinese partner, Chengdu Ya 
Guang  Electronic  Company  Limited,  to  establish  a  semiconductor  manufacturing  facility  for  the  purpose  of  providing  surface 
mounted component production, assembly and testing, and integrated circuit assembly and testing in Chengdu, People’s Republic of 
China.  We initially will own at least 95% of the joint venture.  The manufacturing facility will be developed in phases over a ten year 
period, and we are expected to contribute at least $47.5 million to the joint venture in installments during the first three years.  The 
CDHT will grant the joint venture a fifty year land lease, provide temporary facilities for up to three years at a subsidized rent while 
the joint venture builds the manufacturing facility and provide corporate and employee tax incentives, tax refunds, subsidies and other 
financial support to the joint venture and its qualified employees.  If the joint venture fails to achieve specified levels of investment, 
the investment agreement allows for a renegotiation as well as the option to repay a portion of such financial support.  This is a long-
term, multi-year project that will provide additional capacity once we have reached the maximum production capacity at our Shanghai 
facilities  in  the  next  few  years.    See  “Risk  Factors  -  In  2010,  we  established  a  joint  venture  to  build  a  semiconductor  facility  in 
Chengdu, People’s Republic of China.  We are required to contribute at least $47.5 million to the joint venture during the first three

years with additional contributions thereafter, as well as a substantial amount of time and resources to establish and operate the joint 
venture.  Any failure to meet any such requirements, delays or unforeseen circumstances may cause us to incur penalties or require us 
to contribute additional expenses or resources and, as a result, could have an adverse effect on our operating efficiencies, results of 
operations and financial conditions.” in Part I, Item 1A of this Annual Report for additional information.    

For  the  years  ended  at  December 31,  2010  and  2009,  we  invested  approximately  $68.5  million  and  $18.2  million, 
respectively, in plant and state-of-the-art equipment in China ($283.5 million total investment in China from inception). Both of our 
facilities in China manufacture product for sale by our U.S., Europe and Asia operations, and also sell to external customers.  For the 
years ended at December 31, 2010 and 2009, we invested approximately $86.6 million and $25.9 million, respectively, in equipment, 
primarily related to manufacturing expansion in our facilities in China.  

Silicon wafers are received and inspected in a highly controlled “clean room” environment awaiting the assembly operation.  
During  the  first  step  of  assembly,  the  wafers  are  sawn  with  very  thin,  high  speed  diamond  blades  into  tiny  semiconductor  “dice,” 
numbering  as  many  as  170,000 per  5-inch  diameter  wafer  and  240,000 per  6-inch  diameter  wafer.    Dice  are  then  loaded  onto  a 
handler, which automatically places the dice, one by one, onto lead frames, which are package specific, where they are bonded to the 
lead-frame pad.  Next, automatic wire bonders make the necessary electrical connections from the die to the leads of the lead-frame, 
using micro-thin gold wire for the majority of our products, while some products use copper wire instead.  Also, some of our high 
power  devices  are  clip  bonded  using  copper  clips  or  are  aluminum  bonded  using  aluminum  bond  wires.  Then  our  devices  are  sent 
through  our  fully  automated  assembly  machinery  that  molds  the  epoxy  case  around  the  die  and  lead-frame  to  produce  the  desired 
semiconductor product or are molded manually.  After a trim, form, test, mark and re-test operation for most products, certain parts 
such as surface mounted devices are placed into special carrier housings and a cover tape seals the parts in place, while other devices 
are put into other special packaging.  The surface mounted devices are then spooled onto reels or placed into other packaging medium 
and boxed for shipment.   

Our manufacturing processes use many raw materials, including silicon wafers, aluminum and copper lead frames, gold wire 
and other metals,  molding compounds and various chemicals and gases.  We are continuously evaluating our raw material costs  in 
order to reduce our gold consumption while protecting and maintaining product performance. We have no material agreements with 
any of our suppliers that impose minimum or continuing supply obligations.  From time to time, suppliers may extend lead times, limit 
supplies or increase prices due to capacity constraints or other factors.  Although we believe that supplies of the raw materials we use 
are currently and will continue to be available, shortages could occur in various essential materials due to interruption of supply or 
increased demand in the industry.  See “Risk Factors – We depend on third-party suppliers for timely deliveries of raw materials, parts 
and  equipment,  as  well  as  finished  products  from  other  manufacturers,  and  our  reputation  with  customers,  results  of  operations  and 
financial condition could be adversely affected if we are unable to obtain adequate supplies in a timely manner.” in Part I, Item 1A of this 
Annual Report for additional information. 

Our corporate headquarters are located in a leased facility in Dallas, Texas. We also lease or own properties around the world 
for  use  as  sales  and  administrative  offices,  research  and  development  centers,  manufacturing  facilities,  warehouses  and  logistic 
centers.  The size and/or location of these properties can change from time to time based on our business requirements.  In 2010, we 
purchased an office building in Plano, Texas for approximately $4.1 million, to which we will relocate our corporate headquarters in 
the first half of 2011.  See “Properties” in Part I, Item 2 of this Annual Report for additional information. 

BACKLOG 

The  amount  of  backlog  to  be  shipped  during  any  period  is  dependent  upon  various  factors,  and  all  orders  are  subject  to 
cancellation or modification, usually with no penalty to the customer.  Orders are generally booked from one month to greater than 
twelve months in advance of delivery.  The rate of booking of new orders can vary significantly from month to month.  We, and the 
industry as a whole, have been experiencing a trend towards shorter lead-times, and we expect this trend to continue.  The amount of 
backlog  at  any  date  depends  upon  various  factors,  including  the  timing  of  the  receipt  of  orders,  fluctuations  in  orders  of  existing 
product lines, and the introduction of any new lines.  Accordingly, we believe that the amount of our backlog at any date is not an 
accurate  measure  of  our  future  sales.    We  strive  to  maintain  proper  inventory  levels  to  support  our  customers’  just-in-time  order 
expectations.

PATENTS, TRADEMARKS AND LICENSES 

Historically, patents and trademarks have not been material to our operations, but we expect them to become more important, 

particularly as they relate to our discrete, logic and analog packaging technologies. 

               Our initial product patent portfolio was primarily composed of discrete technologies.  In the late 1990s, our engineers began 
to  research  and  develop  packaging  technologies,  which  produced  several  important  breakthroughs  and  patents,  such  as  the  PowerDI® 
series of packaging technology to foster our growth in the semiconductor industry. 

               We  acquired  Anachip  Corp.  in  early  2006,  a  fabless  semiconductor  company,  which  initiated  our  presence  in  the  analog 
standard product market. 

Through our acquisition of the assets of APD Semiconductor, Inc. in late 2006, we acquired the SBR® patents and trademark.  
SBR® is a state-of-the-art integrated circuit wafer processing technology, which is able to integrate and improve the benefits of the 
two existing rectifier technologies into a single device. The creation of a finite conduction cellular IC, combined with inherent design 
uniformity has allowed manufacturing costs to be kept competitive with the existing power device technology, and thus has produced 
a breakthrough in rectifier technology. 

PowerDI and SBR are registered trademarks of Diodes Incorporated 

               In 2008, we acquired Zetex, which subsequently increased our available discrete and analog technologies with patents and 
trademarks  for  bipolar  transistors  and  power  management  products  such  as  LED  drivers.    LED  drivers  support  a  wide  range  of 
applications for automotive, safety and security, architecture, and portable lighting and are highly efficient and cost effective. 

Currently, our licensing of patents to other companies is not material. We do, however, license certain product technology 
from  other  companies,  but  we  do  not  consider  any  of  the  licensed  technology  currently  to  be  material  in  terms  of  royalties.    We 
believe the duration and other terms of the licenses are appropriate for our current needs. See “Risk Factors – We may be subject to 
claims of infringement of third-party intellectual property rights or demands that we license third-party technology, which could result 
in  significant  expense  and  reduction  in  our  intellectual  property  rights”  in  Part  I,  Item  1A  of  this  Annual  Report  for  additional 
information. 

COMPETITION 

Numerous  semiconductor  manufacturers  and  distributors  serve  the  discrete,  logic  and  analog  semiconductor  components 
market,  making  competition  intense.    Some  of  our  larger  competitors  include  Fairchild  Semiconductor  Corporation,  Infineon 
Technologies  A.G.,  International  Rectifier  Corporation,  ON  Semiconductor  Corporation,  NXP  Semiconductors  N.V.,  Rohm 
Electronics  USA,  LLC,  Toshiba  Corporation  and  Vishay  Intertechnology,  Inc.,  many  of  which  have  greater  financial,  marketing, 
distribution and other resources.  Accordingly, we from time to time may reposition product lines or decrease prices, which may affect 
our sales of, and profit margins on, such product lines.  The price and quality of the products, and our ability to design products and 
deliver customer service in keeping with the customers’ needs, determine the competitiveness of our products.  We believe that our 
product  focus,  packaging  expertise  and  our  flexibility  and  ability  to  quickly  adapt  to  customer  needs  affords  us  competitive 
advantages. See “Risk Factors – The semiconductor business is highly competitive, and increased competition may harm our business, 
results of operations and financial condition.” in Part I, Item 1A of this Annual Report for additional information. 

ENGINEERING AND RESEARCH AND DEVELOPMENT 

Our engineering and research and development groups consist of applications, technical marketing, and product development 
engineers who assist in determining the direction of our future product lines.  Their primary function is to work closely with market-
leading  customers  to  further  refine,  expand  and  improve  our  product  range  within  our  product  types  and  packages.    In  addition, 
customer requirements and acceptance of new package types are assessed and new, higher-density and more energy-efficient packages 
are  developed  to  satisfy  customers’  needs.    Working  with  customers  to  integrate  multiple  types  of  technologies  within  the  same 
package, our applications engineers strive to reduce the required number of components and, thus, circuit board size requirements of a 
device, while increasing the functionality of the component technology. 

Product development engineers work directly with our semiconductor wafer design and process engineers who develop die 
designs needed for products that precisely match our customers’ requirements.  Direct contact with our manufacturing facilities allows 
the manufacturing of products that are in line with current technical requirements.  We have the capability to capture the customers’ 
electrical  and  packaging  requirements  through  their  product  engineers,  and  then  transfer  those  requirements  to  our  research  and 
development  and  engineering  department,  so  the  customers’  requirements  can  be  translated,  designed,  and  manufactured  with  full 
control, even to the elemental silicon level.

For  the  years  ended  December 31,  2010,  2009  and  2008,  Company-sponsored  investment  in  research  and  development 
activities was $26.6 million, $23.8 million and $21.9 million, respectively.  As a percentage of net sales, research and development 
expense  was  4.3%,  5.5%  and  5.1%  for  2010,  2009  and  2008,  respectively.    The  increase  in  2009  was  mainly  due  to  research  and 
development activities associated with the acquisition of Zetex,  offset by our cost reduction efforts during 2009, and the increase in 
2010 was primarily due to increased personnel costs, engineering supplies and material purchases as a result of increased net sales.   

EMPLOYEES 

As of December 31, 2010, we employed a total of 3,986 employees, of which 3,207 of our employees were in Asia, 283 were 
in the United States and 496 were in Europe.  None of our employees in Asia or the United States are subject to a collective bargaining 
agreement,  but  a  majority  of  our  employees  in  Europe  are  covered  by  local  labor  agreements.  We  consider  our  relations  with  our 
employees  to  be  satisfactory.  See  “Risk  Factors  –  We  may  fail  to  attract  or  retain  the  qualified  technical,  sales,  marketing  and 
management personnel required to operate our business successfully, which could adversely affect on our business, results of operations 
and financial condition.” in Part I, Item 1A of this Annual Report for additional information. 

ENVIRONMENTAL MATTERS 

We are subject to a variety of U.S. federal, state, local and foreign governmental laws, rules and regulations related to the use, 
storage,  handling,  discharge or  disposal  of certain  toxic,  volatile  or  otherwise  hazardous  chemicals  used  in  our  manufacturing  process 
both in the U.S. and United Kingdom where our wafer fabrication facilities are located, and in China and Germany where our assembly, 
test and packaging facilities are located.  Any of these regulations could require us to acquire equipment or to incur substantial other costs 
to comply with environmental regulations or remediate problems.  For the years ended December 31, 2010, 2009 and 2008, our capital 
expenditures for environmental controls have not been material. As of December 31, 2010, there were no known environmental claims or 
recorded  liabilities.  See  “Risk  Factors  –  We  are  subject  to  many  environmental  laws  and  regulations  that  could  result  in  significant 
expenses and could adversely affect our business, results of operations and financial condition.” in Part I, Item 1A of this Annual Report 
for additional information. 

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS 

               We conduct business with one related party company, LSC. LSC is our largest stockholder, owning approximately 18.7% of 
our  outstanding  Common  Stock  as  of  December  31,  2010,  and  is  a  member  of  the  Lite-On  Group  of  companies.    C.H.  Chen,  our 
former President and Chief Executive Officer and currently the Vice Chairman of our Board of Directors, is also Vice Chairman of 
LSC and Lite-On Technology Corporation.  Raymond Soong, the Chairman of our Board of Directors, is Chairman of LSC, and is the 
Chairman  of  Lite-On  Technology  Corporation,  a  significant  shareholder  of  LSC.    Dr.  Keh-Shew  Lu,  our  President  and  Chief 
Executive  Officer  and  a  member  of  our  Board  of  Directors,  is  a  member  of  the  Board  of  Directors  of  Lite-On  Technology 
Corporation.    L.P.  Hsu,  a  member  of  our  Board  of  Directors  since  May  2007  serves  as  a  consultant  to  Lite-On  Technology 
Corporation.  We consider our relationship with LSC, a member of the Lite-On Group of companies, to be mutually beneficial, and we 
plan to continue our strategic alliance with LSC. 

               We also conduct business with one significant company, Keylink International (B.V.I.) Inc., and its subsidiaries and affiliates 
(“Keylink”).  Keylink is our 5% joint venture partner in our Shanghai manufacturing facilities. 

The Audit Committee of our Board of Directors reviews all related party transactions for potential conflict of interest situations 
on an ongoing basis, all in accordance with such procedures as the Audit Committee may adopt from time to time. We believe that all 
related party transactions are on terms no less favorable to us than would be obtained from unaffiliated third parties. 

We sold products to LSC totaling 1.1%, 2.1% and 3.5% of our net sales for the years ended December 31, 2010, 2009 and 2008, 
respectively, making LSC one of our largest customers. Also for the years ended December 31, 2010, 2009 and 2008, 6.9%, 6.3% and 
9.6%, respectively, of our net sales were from semiconductor products purchased from LSC for subsequent sale, making LSC our largest 
supplier.  We  also  rent  warehouse  space  in  Hong  Kong  with  a  lease  term  ending  March  2011  from  a  member  of  the  Lite-On  Group.  
During 2010 the warehousing function in Hong Kong was moved to a separate facility managed by a third party and therefore, we do not 
plan to renew the lease. For the years ended December 31, 2010, 2009 and 2008, we paid this entity $0.2 million, $0.8 million and $0.7 
million, respectively.   

In addition, we sell products to, and purchase inventory from, companies owned by Keylink.  We sold products to companies 
owned by Keylink, totaling 2.5%, 2.6% and 0.8% of net sales for the years ended December 31, 2010, 2009 and 2008, respectively. 
Also  for  the  years  ended  December  31,  2010,  2009  and  2008,  1.9%,  1.2%  and  1.3%,  respectively,  of  our  net  sales  were  from

semiconductor  products  purchased  from  companies  owned  by  Keylink.  In  addition,  our  subsidiaries  in  China  lease  our  Shanghai 
manufacturing facilities from, and subcontract a portion of their manufacturing process (metal plating and environmental services) to, 
Keylink.  We also pay a consulting fee to Keylink. The aggregate amounts for these services for the years ended December 31, 2010, 
2009  and  2008  were  $14.4  million,  $10.7  million  and  $10.5  million,  respectively.    See  “Risk  Factors  –  We  receive  a  significant 
portion of our net sales from two customers. In addition, one of these customers is our largest external supplier and both are related 
parties. The loss of these customers or suppliers could harm our business, results of operations and financial condition.” in Part I, 
Item 1A  and Note 18 of “Notes to Consolidated Financial Statements” of this Annual Report for additional information. 

SEASONALITY 

Historically, our net sales have been affected by the cyclical nature of the semiconductor industry and the seasonal trends of 
related  end  markets,  specifically  in  the  consumer  and  computing  markets.    See  Note  21  (unaudited)  of  “Notes  to  Consolidated 
Financial Statements” of this Annual Report for additional information on our quarterly results.

Risk Factors  

Investing in our Common Stock involves a high degree of risk.  You should carefully consider the following risks and other 
information in this report before you decide to buy our Common Stock.  Our business, financial condition or operating results may 
suffer if any of the following risks are realized.  Additional risks and uncertainties not currently known to us may also adversely affect 
our business, financial condition or operating results.  If any of these risks or uncertainties occurs, the trading price of our Common 
Stock could decline and you could lose part or all of your investment. 

RISKS RELATED TO OUR BUSINESS 

The  success  of  our  business  depends  on  the  strength  of  the  global  economy  and  the  stability  of  the  financial  markets,  and  any 
weaknesses in these areas may have a material adverse effect on our revenues, results of operations and financial condition.  

Weaknesses in the global economy and financial markets can lead to lower consumer discretionary spending and demand for 
items that incorporate our products in the consumer electronics, computing, industrial, communications and the automotive sectors. A 
decline in end-user demand can affect our customers’ demand for  our products, the ability of our customers to  meet their payment 
obligations  and  the  likelihood  of  customers  canceling  or  deferring  existing  orders.  Our  revenues,  operating  results  and  financial 
condition could be negatively affected by such actions.   

During  times  of  difficult  market  conditions,  our  fixed  costs  combined  with  lower  revenues  may  have  a  negative  impact  on  our 
business, results of operations and financial condition. 

               The  semiconductor  industry  is  characterized  by  high  fixed  costs.  Notwithstanding  our  utilization  of  third-party 
manufacturing  capacity,  most  of  our  production  requirements  are  met  by  our  own  manufacturing  facilities.  In  difficult  economic 
environments  we  could  be  faced  with  a  decline  in  the  utilization  rates  of  our  manufacturing  facilities  due  to  decreases  in  product 
demand. During such periods, our fabrication plants do not operate at full capacity and the costs associated with this excess capacity 
are expensed immediately and not capitalized into inventory. This was the case at the end of 2008 and beginning of 2009 when our 
utilization rates declined to abnormally low production levels, which resulted in lower gross margins. The market conditions in the 
future may adversely affect our utilization rates and consequently our future gross margins, and this, in turn, could have a material 
negative impact on our business, results of operations and financial condition. 

Downturns in the highly cyclical semiconductor industry or changes in end-market demand could adversely affect our results of 
operations and financial condition. 

The  semiconductor  industry  is  highly  cyclical,  and  periodically  experiences  significant  economic  downturns  characterized  by 
diminished product demand, production overcapacity and excess inventory, which can result in rapid erosion in average selling prices.  
From time to time, the semiconductor industry experiences order cancellations and reduced demand for products, resulting in significant 
revenue  declines,  due  to  excess  inventories  at  computer  and  telecommunications  equipment  manufacturers  and  general  economic 
conditions, especially in the technology sector.  The market for semiconductors may experience renewed, and possibly more severe and 
prolonged downturns in the future, which may harm our results of operations and reduce the value of our business. 

In addition, we operate in a few narrow markets of the broader semiconductor market and, as a result, cyclical fluctuations 
may affect these segments to a greater extent than they do to the broader semiconductor market.  This may cause us to experience 
greater fluctuations in our results of operations than compared to some of our broad line semiconductor manufacturer competitors.  In 
addition, we may experience significant changes in our profitability as a result of variations in sales, changes in product mix, changes 
in end-user markets and the costs associated with the introduction of new products.  The markets for our products depend on continued 
demand in the consumer electronics, computing, communications, industrial and automotive sectors. These end-user markets also tend 
to be cyclical and may also experience changes in demand that could adversely affect our results of operations and financial condition. 

The  semiconductor  business  is  highly  competitive,  and  increased  competition  may  harm  our  business,  results  of 

operations and financial condition. 

The  semiconductor  industry  in  which  we  operate  is  highly  competitive.  We  expect  intensified  competition  from  existing 
competitors and new entrants. Competition is based on price, product performance, product availability, quality, reliability and customer 
service.  We  compete  in  various  markets  with  companies  of  various  sizes,  many  of  which  are  larger  and  have  greater  resources  or 
capabilities as it relates to financial, marketing, distribution, brand name recognition, research and development, manufacturing and other 
resources than we have. As a result, they may be better able to develop new products, market their products, pursue acquisition candidates 
and  withstand  adverse  economic  or  market  conditions.    Most  of  our  current  major  competitors  are  broad  line  semiconductor 
manufacturers who often have a wider range of product types and technologies than we do. In addition, companies not currently in direct 

- 14 - 
-14-

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
competition  with  us  may  introduce  competing  products  in  the  future.    Some  of  our  current  major  competitors  are  Fairchild 
Semiconductor Corporation, Infineon Technologies A.G., International Rectifier Corporation, ON Semiconductor Corporation, NXP 
Semiconductors  N.V.,  Rohm  Electronics USA,  LLC, Toshiba  Corporation  and Vishay  Intertechnology,  Inc. We may not be able to 
compete successfully in the future, and competitive pressures may harm our business, results of operations and financial condition. 

We receive a significant portion of our net sales from two customers. In addition, one of these customers is our largest external 
supplier and both are related parties. The loss of these customers or suppliers could harm our business, results of operations and 
financial condition. 

In 2010, 2009 and 2008, LSC, our largest stockholder and one of our largest customers, accounted for 1.1%, 2.1% and 3.5%, 
respectively, of our net sales.  LSC is also our largest supplier, providing us with discrete semiconductor products for subsequent sale by 
us, which represented approximately 6.9%, 6.3% and 9.6%, respectively, of our net sales, in 2010, 2009 and 2008.  In addition, in 2010, 
2009 and 2008, we sold products to companies owned by Keylink, totaling 2.5%, 2.6% and 0.8%, respectively.  Also for 2010, 2009 
and 2008, 1.9%, 1.2% and 1.3%, respectively, of our net sales were from semiconductor products purchased from companies owned 
by Keylink. 

The loss of LSC as either a customer or a supplier, or Keylink as a customer, or any significant reductions in either the amount 
of products LSC supplies to us, or the volume of orders LSC or Keylink places with us, could materially harm our business, results of 
operations and financial condition. 

Delays  in  initiation  of  production  at  facilities,  implementing  new  production  techniques  or  resolving  problems  associated  with 
technical  equipment  malfunctions  could  adversely  affect  our  manufacturing  efficiencies,  results  of  operations  and  financial 
condition. 

Our manufacturing efficiency has been and will be an important factor in our future profitability, and we may not be able to 
maintain or increase our manufacturing efficiency. Our manufacturing and testing processes are complex, require advanced and costly 
equipment and are continually being modified in our efforts to improve yields and product performance. Difficulties in the manufacturing 
process can lower yields.  Technical or other problems could lead to production delays, order cancellations and lost revenue.  In addition, 
any problems in achieving acceptable yields, construction delays, or other problems in upgrading or expanding existing facilities, building 
new facilities, problems in bringing other new manufacturing capacity to full production or changing our process technologies, could also 
result  in  capacity  constraints,  production  delays  and  a  loss  of  future  revenues  and  customers.    Our  operating  results  also  could  be 
adversely affected by any increase in fixed costs and operating expenses related to increases in production capacity if net sales do not 
increase proportionately, or in the event of a decline in demand for our products. 

Our  wafer  fabrication  facilities  are  located  near  Kansas  City,  Missouri,  and  Manchester,  England,  while  our  facilities  in 
Shanghai, China and Neuhaus, Germany perform packaging, assembly and testing functions and our fourth facility is being developed in 
Chengdu,  China  for  the  purpose  of  providing  surface  mounted  component  production,  assembly  and  testing,  and  integrated  circuit 
assembly  and  testing.  Any  disruption  of  operations  at  these  facilities  could  have  a  material  adverse  effect  on  our  manufacturing 
efficiencies, results of operations and financial condition. 

We are and will continue to be under continuous pressure from our customers and competitors to reduce the price of our products, 
which could adversely affect our growth and profit margins. 

Prices for our products tend to decrease over their life cycle.  There is substantial and continuing pressure from customers to 
reduce the total cost of purchasing our products.  To remain competitive and retain our customers and gain new ones, we must continue to 
reduce  our  costs  through  product  and  manufacturing  improvements.    We  must  also  strive  to  minimize  our  customers’  shipping  and 
inventory financing costs and to meet their other goals for rationalization of supply and production.  We experienced a increase in average 
selling prices (“ASP”) for our products of 5.6% in 2008, a decrease of 2.1% in 2009 and an increase of 5.1% in 2010. At times, we may 
be required to sell our products at ASP’s below our manufacturing cost or purchase price in order to remain competitive.  Our growth and 
the  profit  margins  of  our  products  will  suffer  if  we  cannot  effectively  continue  to  reduce  our  costs  and  keep  our  product  prices 
competitive. 

Our customers require our products to undergo a lengthy and expensive qualification process without any assurance of product 
sales, which could adversely affect our revenues, results of operations and financial condition.  

Prior to purchasing our products, our customers require that our products undergo an extensive qualification process, which 
involves  rigorous  reliability  testing.  This  qualification  process  may  continue  for  six  months  or  longer.  However,  qualification  of  a 
product by a customer does not ensure any sales of the product  to that  customer. Even after successful qualification and sales of a 
product to a customer, a subsequent revision to the device, changes in the device's manufacturing process or the selection of a new

supplier by us may require a new qualification process, which may  result in delays and in us holding excess or obsolete inventory. 
After our products are qualified, it can take an additional six months or more before the customer commences volume production of 
components or devices that incorporate our products. Despite these uncertainties, we devote substantial resources, including design, 
engineering, sales, marketing and management efforts, toward qualifying our products with customers in anticipation of sales. If we 
are unsuccessful or delayed in qualifying any of our products with a customer, such failure or delay would preclude or delay sales of 
such product to the customer, which may impede our revenues, results of operations and financial condition.  

Our customer orders are subject to cancellation or modification usually with no penalty. High volumes of order cancellation or 
reductions in quantities ordered could adversely affect our results of operations and financial condition. 

All of our customer orders are subject to cancellation or modification, usually with no penalty to the customer. Orders are 
generally  made  on  a  purchase  order  basis,  rather  than  pursuant  to  long-term  supply  contracts,  and  are  booked  from  one  to  twelve 
months  in  advance  of  delivery.    The  rate  of  booking  new  orders  can  vary  significantly  from  month  to  month.    We,  and  the 
semiconductor industry as a whole, are experiencing a trend towards shorter lead-times, which is the amount of time between the date 
a  customer  places  an  order  and  the  date  the  customer  requires  shipment.    Furthermore,  our  industry  is  subject  to  rapid  changes  in 
customer outlook and periods of excess inventory due to changes in demand in the end markets our industry serves.  As a result, many 
of our purchase orders are revised, and may be cancelled, with little or no penalty and with little or no notice.  However, we must still 
commit  production  and  other  resources  to  fulfilling  these  orders  even  though  they  may  ultimately  be  cancelled.    If  a  significant 
number of orders are cancelled or product quantities ordered are reduced, and we are unable to timely generate replacement orders, we 
may build up excess inventory and our results of operations and financial condition may suffer. 

Production  at  our  manufacturing  facilities  could  be  disrupted  for  a  variety  of  reasons,  which  could  prevent  us  from  producing 
enough  of  our  products  to  maintain  our  sales  and  satisfy  our  customers’  demands  and  could  adversely  affect  our  results  of 
operations and financial condition. 

              A disruption in production at our manufacturing facilities could have a material adverse effect on our business. Disruptions 
could  occur  for  many  reasons,  including  labor  shortages,  fire,  natural  disasters,  weather,  unplanned  maintenance  or  other 
manufacturing  problems,  disease,  strikes,  transportation  interruption,  government  regulation  or  terrorism.  Alternative  facilities  with 
sufficient capacity or capabilities may not be available, may cost substantially more or may take a significant time to start production, 
each of which could negatively affect our business and financial performance. If one of our key manufacturing facilities is unable to 
produce our products for an extended period of time, our sales may be reduced by the shortfall caused by the disruption, and we may 
not be able to meet our customers’ needs, which could cause them to seek other suppliers. Such disruptions could have an adverse 
effect on our results of operations and financial condition. 

New technologies could result in the development of new products by our competitors and a decrease in demand for our products, 
and we may not be able to develop new products to satisfy changes in demand, which would adversely affect our net sales, market 
share, results of operations and financial condition. 

Our product range and new product development program is focused on discrete, logic and analog semiconductor products. Our 
failure  to  develop  new  technologies,  or  anticipate  or  react  to  changes  in  existing  technologies,  either  within  or  outside  of  the 
semiconductor market, could materially delay development of new products, which could result in a decrease in our net sales and a loss of 
market share to our competitors.  The semiconductor industry is characterized by rapidly changing technologies and industry standards, 
together  with  frequent  new  product  introductions.    This  includes  the  development  of  new  types  of  technology  or  the  improvement  of 
existing technologies, such as analog and digital technologies that compete with, or seek to replace discrete semiconductor technology.  
Our financial performance depends on our ability to design, develop, manufacture, assemble, test, market and support new products and 
product  enhancements  on  a  timely  and  cost-effective  basis.  New  products  often  command  higher  prices  and,  as  a  result,  higher  profit 
margins.  We may not successfully identify new product opportunities or develop and bring new products to market or succeed in selling 
them into new customer applications in a timely and cost-effective manner. 

Products or technologies developed by other companies may render our products or technologies obsolete or noncompetitive and, since 
we operate primarily in a narrower segment of the broader semiconductor industry, this may have a greater effect on us than it would if 
we were a broad-line semiconductor manufacturer with a wider range of product types and technologies.  Many of our competitors are 
larger  and  more  established  international  companies  with  greater  engineering  and  research  and  development  resources  than  us.    Our 
failure to identify or capitalize on any fundamental shifts in technologies in our product markets, relative to our competitors, could harm 
our  business,  have  a  material  adverse  effect  on  our  competitive  position  within  our  industry  and  harm  our  relationships  with  our 
customers. In addition, to remain competitive, we must continue to reduce package sizes, improve manufacturing yields and expand our 
sales.  We may not be able to accomplish these goals, which would adversely affect our net sales, market share, results of operations 
and financial condition.

We  may  be  adversely  affected  by  any  disruption  in  our  information  technology  systems,  which  could  adversely  affect  our  cash 
flows, results of operations and financial condition. 

Our  operations  are  dependent  upon  our  information  technology  systems,  which  encompass  all  of  our  major  business 
functions. We rely upon such information technology systems to manage and replenish inventory, to fill and ship customer orders on a 
timely basis, to coordinate our sales activities across all of our products and services and to coordinate our administrative activities. A 
substantial  disruption  in  our  information  technology  systems  for  any  prolonged  time  period  (arising  from,  for  example,  system 
capacity  limits  from  unexpected  increases  in  our  volume  of  business,  outages  or  delays  in  our  service)  could  result  in  delays  in 
receiving inventory and supplies or filling customer orders and adversely affect our customer service and relationships. Our systems 
might be damaged or interrupted by natural or man-made events or by computer viruses, physical or electronic break-ins and similar 
disruptions  affecting  the  global  Internet.  There  can  be  no  assurance  that  such  delays,  problems,  or  costs  will  not  have  a  material 
adverse effect on our cash flows, results of operations and financial condition. 

As  our  operations  grow  in  both  size  and  scope,  we  will  continuously  need  to  improve  and  upgrade  our  systems  and 
infrastructure  while  maintaining  the  reliability  and  integrity  of  our  systems  and  infrastructure.  The  expansion  of  our  systems  and 
infrastructure will require us to commit substantial financial, operational and technical resources before the volume of our business 
increases, with no assurance that the volume of business will increase. In particular, we have upgraded our financial reporting system 
and  are  currently  seeking  to  upgrade  other  information  technology  systems.  These  and  any  other  upgrades  to  our  systems  and 
information technology, or new technology, now and in the future, will require that our management and resources be diverted from 
our  core  business  to  assist  in  compliance  with  those  requirements.  There  can  be  no  assurance  that  the  time  and  resources  our 
management  will  need  to  devote  to  these  upgrades,  service  outages  or  delays  due  to  the  installation  of  any  new  or  upgraded 
technology (and customer issues therewith), or the impact on the reliability of our data from any new or upgraded technology will not 
have a material adverse effect on our cash flows, results of operations and financial condition. 

All of our operations, other than Diodes FabTech Inc. and Diodes Zetex Limited, operate on a single technology platform.  To 
manage  our  international  operations  efficiently  and  effectively,  we  rely  heavily  on  our  Enterprise  Resource  Planning  (ERP)  system, 
internal electronic information and communications systems and on systems or support services from third parties. Any of these systems 
are subject to electrical or telecommunications outages, computer hacking or other general system failure.  It is also possible that future 
acquisitions will operate on ERP systems different from ours and that we could face difficulties in integrating operational and accounting 
functions of new acquisitions.  Difficulties in upgrading or expanding our ERP system or system-wide or local failures that affect our 
information processing could have a material adverse effect on our cash flows, results of operations and financial condition 

We  may  be  subject  to  claims  of  infringement  of  third-party  intellectual  property  rights  or  demands  that  we  license  third-party 
technology, which could result in significant expense and reduction in our intellectual property rights. 

The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights. From time to time, 
third parties have asserted, and may in the future assert, patent, copyright, trademark and other intellectual property rights to technologies 
that are important to our business and have demanded, and may in the future demand, that we license their patents and technology.  Any 
litigation to determine the validity of allegations that our products infringe or may infringe these rights, including claims arising through 
our contractual indemnification of our customers, or claims challenging the validity of our patents, regardless of its merit or resolution, 
could be costly and divert the efforts and attention of our management and technical personnel.  We may not prevail in litigation given the 
complex technical issues and inherent uncertainties in intellectual property litigation. If litigation results in an adverse ruling we could be 
required to: 

(cid:190)  pay substantial damages for past, present and future use of the infringing technology; 
(cid:190)  cease the manufacture, use or sale of infringing products; 
(cid:190)  discontinue the use of infringing technology; 
(cid:190)  expend significant resources to develop non-infringing technology; 
(cid:190)  pay  substantial  damages  to  our  customers  or  end-users  to  discontinue  use  or  replace  infringing  technology  with  non-

(cid:190) 

(cid:190) 

infringing technology; 
license  technology  from  the  third  party  claiming  infringement,  which  license  may  not  be  available  on  commercially 
reasonable terms, or at all; or 
relinquish  intellectual  property  rights  associated  with  one  or  more  of  our  patent  claims,  if  such  claims  are  held  invalid  or 
otherwise unenforceable.

We depend on third-party suppliers for timely deliveries of raw materials, parts and equipment, as well as finished products from 
other manufacturers, and our reputation with customers, results of operations and financial condition could be adversely affected 
if we are unable to obtain adequate supplies in a timely manner. 

Our manufacturing operations depend upon obtaining adequate supplies of raw materials, parts and equipment on a timely basis 
from third parties.  Our results of operations could be adversely affected if we are unable to obtain adequate supplies of raw materials, 
parts and equipment in a timely manner or if the costs of raw materials, parts or equipment were to increase significantly.  Our business 
could also be adversely affected if there is a significant degradation in the quality of raw materials used in our products, or if the raw 
materials give rise to compatibility or performance issues in our products, any of which could lead to an increase in customer returns or 
product  warranty  claims.    Although  we  maintain  rigorous  quality  control  systems,  errors  or  defects  may  arise  from  a  supplied  raw 
material  and  be  beyond  our  detection  or  control.    Any  interruption  in,  or  change  in  quality  of,  the  supply  of  raw  materials,  parts  or 
equipment needed to manufacture our products could adversely affect our reputation with customers, results of operations and financial 
condition. 

In  addition,  we  sell  finished  products  from  other  manufacturers.    Our  business  could  also  be  adversely  affected  if  there  is  a 
significant degradation in the quality of these products.  From time to time, such manufacturers may extend lead-times, limit supplies or 
increase prices due to capacity constraints or other factors.  We have no long-term purchase contracts with any of these manufacturers 
and,  therefore,  have  no  contractual  assurances  of  continued  supply,  pricing  or  access  to  finished  products  that  we  sell,  and  any  such 
manufacturer could discontinue supplying to us at any time.  Additionally, some of our suppliers of finished products or wafers compete 
directly with us and may in the future choose not to supply products to us. 

If  we  do  not  succeed  in  continuing  to  vertically  integrate  our  business,  we  will  not  realize  the  cost  and  other  efficiencies  we 
anticipate, which could adversely affect our ability to compete, profit margins, results of operations and financial condition. 

We are continuing to vertically integrate our business.  Key elements of this strategy include continuing to expand the reach of 
our  sales  organization,  expand  our  manufacturing  capacity,  expand  our  wafer  foundry  and  research  and  development  capability  and 
expand  our  marketing,  product  development,  package  development  and  assembly/testing  operations  in  company-owned  facilities  or 
through the acquisition of established contractors.  There are certain risks associated with our vertical integration strategy, including: 

(cid:190)  difficulties associated with owning a manufacturing business, including, but not limited to, the maintenance and management 
of manufacturing facilities, equipment, employees and inventories and limitations on the flexibility of controlling overhead; 
(cid:190)  difficulties in continuing expansion of our operations in Asia and Europe, because of the distance from our U.S. headquarters 

and differing regulatory and cultural environments; 
the need for skills and techniques that are outside our traditional core expertise; 
less flexibility in shifting manufacturing or supply sources from one region to another; 

(cid:190) 
(cid:190) 
(cid:190)  even when independent suppliers offer lower prices, we would continue to acquire wafers from our captive manufacturing 

facilities, which may result in us having higher costs than our competitors; 

(cid:190)  difficulties developing and implementing a successful research and development team; and 
(cid:190)  difficulties developing, protecting, and gaining market acceptance of, our proprietary technology. 

The risks of becoming a fully integrated manufacturer are amplified in an industry-wide slowdown because of the fixed costs 
associated with manufacturing facilities.  In addition, we may not realize the cost, operating and other efficiencies that we expect from 
continued vertical integration.  If we fail to successfully vertically integrate our business, our ability to compete, profit margins, results of 
operations and financial condition may suffer. 

Part of our growth strategy involves identifying and acquiring companies with complementary product lines or customers. We may 
be unable to identify suitable acquisition candidates or consummate desired acquisitions and, if we do make any acquisitions, we 
may be unable to successfully integrate any acquired companies with our operations, which could adversely affect our business, 
results of operations and financial condition. 

A significant part of our growth strategy involves acquiring companies with complementary product lines, customers or other 
capabilities.  For example, (i) in 2000, we acquired Diodes FabTech Inc., a wafer fabrication company, in order to have our own wafer 
manufacturing capabilities, (ii) in 2006, we acquired Anachip Corp. as an entry into standard logic markets, (iii) in 2006, we acquired 
the  net  operating  assets  of  APD  Semiconductor  and  (iv)  in  2008,  we  acquired  Zetex  plc.    While  we  do  not  currently  have  any 
agreements or commitments in place with respect to any material acquisitions, we are in various stages of preliminary discussions, and we 
intend  to  continue  to  expand  and  diversify  our  operations  by  making  further  acquisitions.  However,  we  may  be  unsuccessful  in 
identifying  suitable  acquisition  candidates,  or  we  may  be  unable  to  consummate  a  desired  acquisition.    To  the  extent  we  do  make 
acquisitions,  if  we  are  unsuccessful  in  integrating  these  companies  or  their  operations  or  product  lines  with  our  operations,  or  if 
integration is more difficult than anticipated, we may experience disruptions that could have a material adverse effect on our business, 

-18-

results of operations and financial condition.  In addition, we may not realize all of the benefits we anticipate from any such acquisitions.  
Some of the risks that may affect our ability to integrate or realize any anticipated benefits from acquisitions that we may make include 
those associated with: 

(cid:190)  unexpected losses of key employees or customers of the acquired company; 
(cid:190)  bringing the acquired company’s standards, processes, procedures and controls into conformance with our operations; 
(cid:190)  coordinating our new product and process development; 
(cid:190)  hiring additional management and other critical personnel; 
(cid:190) 
increasing the scope, geographic diversity and complexity of our operations; 
(cid:190)  difficulties in consolidating facilities and transferring processes and know-how; 
(cid:190)  difficulties in reducing costs of the acquired entity’s business; 
(cid:190)  diversion of management’s attention from the management of our business; and 
(cid:190)  adverse effects on existing business relationships with customers. 

We are subject to many environmental laws and regulations that could result in significant expenses and could adversely affect our 
business, results of operations and financial condition. 

We are subject to a variety of U.S. federal, state, local and foreign governmental laws, rules and regulations related to the use, 
storage,  handling,  discharge or  disposal  of certain  toxic,  volatile  or  otherwise  hazardous  chemicals  used  in  our  manufacturing  process 
both in the United States and England where our wafer fabrication facilities are located, in China and Germany where our assembly, test 
and packaging facilities are located, and in Taiwan where our analog products were produced through 2007.  Some of these regulations in 
the  United  States  include  the  Federal  Clean  Water  Act,  Clean  Air  Act,  Resource  Conservation  and  Recovery  Act,  Comprehensive 
Environmental  Response,  Compensation,  and  Liability  Act  and  similar  state  statutes  and  regulations.    Any  of  these  regulations  could 
require us to acquire equipment or to incur substantial other expenses to comply with environmental regulations.  If we were to incur such 
additional expenses, our product costs could significantly increase, materially affecting our business, financial condition and results of 
operations.  Any failure to comply with present or future environmental laws, rules and regulations could result in fines, suspension of 
production  or  cessation  of  operations,  any  of  which  could  have  a  material  adverse  effect  on  our  business,  results  of  operations  and 
financial condition.  Our operations affected by such requirements include, among others: the disposal of wastewater containing residues 
from our manufacturing operations through publicly operated treatment works or sewer systems, and which may be subject to volume and 
chemical discharge limits and may also require discharge permits; and the use, storage and disposal of materials that may be classified as 
toxic or hazardous.  Any of these may result in, or may have resulted in, environmental conditions for which we could be liable. 

Some  environmental  laws  impose  liability,  sometimes  without  fault,  for  investigating  or  cleaning  up  contamination  on,  or 
emanating from, our currently or formerly owned, leased or operated properties, as well as for damages to property or natural resources 
and for personal injury arising out of such contamination.  Such liability may also be joint and several, meaning that we could be held 
responsible  for  more  than  our  share  of  the  liability  involved,  or  even  the  entire  liability.  In  addition,  the  presence  of  environmental 
contamination could also interfere with ongoing operations or adversely affect our ability to sell or lease our properties.  Environmental 
requirements may also limit our ability to identify suitable sites for new or expanded plants.    Discovery of contamination for which we 
are responsible, the enactment of new laws and regulations, or changes in how existing requirements are enforced, could require us to 
incur additional costs for compliance or subject us to unexpected liabilities. 

Our products may be found to be defective and, as a result, product liability claims may be asserted against us, which may harm 
our business, reputation with our customers, results of operations and financial condition. 

Our products are typically sold at prices that are significantly lower than the cost of the equipment or other goods in which they 
are incorporated.  For example, our products that are incorporated into a personal computer may be sold for several cents, whereas the 
computer maker might sell the personal computer for several hundred dollars.  Although we maintain rigorous quality control systems, we 
shipped approximately 27.9 billion, 19.0 billion and 18.5 billion individual semiconductor devices in years ended at December 31, 2010, 
2009 and 2008, respectively, to customers around the world, and in the ordinary course of our business, we receive warranty claims for 
some of these products that are defective, or that do not perform to published specifications.  Since a defect or failure in our products 
could give rise to failures in the end products that incorporate them (and consequential claims for damages against our customers from 
their  customers),  we  may  face  claims  for  damages  that  are  disproportionate  to  the  revenues  and  profits  we  receive  from  the  products 
involved.  In addition, our ability to reduce such liabilities may be limited by the laws or the customary business practices of the countries 
where we do business.  Even in cases where we do not believe we have legal liability for such claims, we may choose to pay for them to 
retain a customer’s business or goodwill or to settle claims to avoid protracted litigation.  Our results of operations and business could be 
adversely affected as a result of a significant quality or performance issue in our products, if we are required or choose to pay for the 
damages that result.  Although we currently have product liability insurance, we may not have sufficient insurance coverage, and we may 
not have sufficient resources, to satisfy all possible product liability claims.  In addition, any perception that our products are defective 

-19-
- 19 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
would likely result  in reduced sales of our products, loss of customers and harm  to our business, reputation, results of operations and 
financial condition. 

We  may  fail  to  attract  or  retain  the  qualified  technical,  sales,  marketing  and  management  personnel  required  to  operate  our 
business successfully, which could adversely affect on our business, results of operations and financial condition. 

Our  future  success  depends,  in  part,  upon  our  ability  to  attract  and  retain  highly  qualified  technical,  sales,  marketing  and 
managerial personnel. Personnel with the necessary expertise are scarce and competition for personnel with these skills is intense.  We 
may not be able to retain existing key technical, sales, marketing and managerial employees or be successful in attracting, assimilating or 
retaining  other  highly  qualified  technical,  sales,  marketing  and  managerial  personnel  in  the  future.    For  example,  we  have  faced,  and 
continue  to  face,  intense  competition  for  qualified  technical  and  other  personnel  in  Shanghai,  China,  where  our  assembly,  test  and 
packaging  facilities  are  located.    A  number  of  U.S.  and  multi-national  corporations,  both  in  the  semiconductor  industry  and  in  other 
industries,  have  recently  established  and  are  continuing  to  establish  factories  and  plants  in  Shanghai,  China,  and  the  competition  for 
qualified  personnel  has  increased  significantly  as  a  result.    If  we  are  unable  to  retain  existing  key  employees  or  are  unsuccessful  in 
attracting new highly qualified employees, our business, results of operations and financial condition could be materially and adversely 
affected. 

We may not be able to maintain our growth or achieve future growth and such growth may place a strain on our management and 
on our systems and resources, which could adversely affect our business, results of operations and financial condition. 

Our ability to successfully grow our business within the semiconductor industry requires effective planning and management.  
Our past growth, and our targeted future growth, may place a significant strain on our management and on our systems and resources, 
including our financial and  managerial controls, reporting systems  and procedures.  In addition, we will need  to continue to  train and 
manage our workforce worldwide.  If we are unable to effectively plan and manage our growth effectively, our business and prospects 
will  be  harmed  and  we  will  not  be  able  to  maintain  our  profit  growth  or  achieve  future  growth,  which  could  adversely  affect  our 
business, results of operations and financial condition. 

Obsolete inventories as a result of changes in demand for our products and change in life cycles of our products could adversely 
affect our business, results of operations and financial condition. 

The life  cycles of some of our products depend heavily upon the life cycles of the end products into which our products are 
designed.  End-market products with short life cycles require us to manage closely our production and inventory levels. Inventory may 
also  become  obsolete  because  of  adverse  changes  in  end-market  demand.  We  may  in  the  future  be  adversely  affected  by  obsolete  or 
excess  inventories  which  may  result  from  unanticipated  changes  in  the  estimated  total  demand  for  our  products  or  the  estimated  life 
cycles  of  the  end  products  into  which  our  products  are  designed.    In  addition,  some  customers  restrict  how  far  back  the  date  of 
manufacture for our products can be and certain customers may stop ordering products from us and  go out of business due to adverse 
economic conditions; therefore, some of our product inventory may become obsolete and, thus, adversely affect our business, results of 
operations and financial condition. 

 If OEMs do not design our products into their applications, a portion of our net sales may be adversely affected. 

We expect an increasingly significant portion of net sales  will come from products we design specifically for our customers.  
However, we may be unable to achieve these design wins.  In addition, a design win from a customer does not guarantee future sales to 
that customer.  Without design wins from OEMs, we would only be able to sell our products to these OEMs as a second source, which 
usually means we are only able to sell a limited amount of product to them.  Once an OEM designs another supplier’s semiconductors 
into  one  of  its  product  platforms,  it  is  more  difficult  for  us  to  achieve  future  design  wins  with  that  OEM’s  product  platform  because 
changing suppliers involves significant cost, time, effort and risk to an OEM.  Achieving a design win with a customer does not ensure 
that we will receive significant revenues from that customer, and we may be unable to convert design wins into actual sales.  Even after a 
design win, the customer is not obligated to purchase our products and can choose at any time to stop using our products, if, for example, 
its own products are not commercially successful. 

We are subject to interest rate risk that could have an adverse effect on our cost of working capital and interest expenses. 

We have credit facilities with financial institutions in U.S., Asia and Europe, as well as other debt instruments, with interest 
rates equal to LIBOR or similar indices plus a negotiated margin.  A rise in interest rates could have an adverse impact upon our cost 
of working capital and our interest expense. As of December 31, 2010, our outstanding interest-bearing debt included $134.3 million 
principal amount of Notes with a fixed rate of 2.25%.  An increase of 1.0% in interest rates on our credit facilities, which currently 
have no outstanding borrowings, would increase our annual interest rate expense by approximately $0.5 million.

We  had  a  significant  amount  of  debt  following  the  offering  of  convertible  notes.  Our  substantial  indebtedness  could  adversely 
affect our business, results of operations, financial condition and our ability to meet our payment obligations under the notes and 
or other debt.  

Following the offering of our Notes, we had a significant amount of debt and substantial debt service requirements. As of 
December  31,  2010,  we  had  outstanding  debt,  including  $134.3  million  principal  amount  of  Notes  with  a  fixed  rate  of  2.25%.    In 
addition, $46.7 million is available for future borrowings under our credit facilities in the U.S., Asia and Europe, and we are permitted 
under the terms of our debt agreements to incur substantial additional debt. 

This level of debt could have significant consequences on our future operations, including: 

(cid:190)  making it more difficult for us to meet our payment and other obligations under the Notes and our other outstanding debt; 
(cid:190)  resulting in an event of default if we fail to comply with the  financial and other restrictive covenants contained in our debt 
agreements, which event of default could result in all of our debt becoming immediately due and payable and, in the case of 
an event of default under our secured debt, such as our senior secured credit facility, could permit the lenders to foreclose on 
our assets securing that debt; 

(cid:190)  reducing  the  availability  of  our  cash  flow  to  fund  working  capital,  capital  expenditures,  acquisitions  and  other  general 

corporate purposes, and limiting our ability to obtain additional financing for these purposes; 

(cid:190)  subjecting  us  to  the  risk  of  increased  sensitivity  to  interest  rate  increases  on  our  indebtedness  with  variable  interest  rates, 

including borrowings under senior secured credit facility; 

(cid:190)  limiting  our  flexibility  in  planning  for,  or  reacting  to,  and  increasing  our  vulnerability  to,  changes  in  our  business,  the 

industry in which we operate and the general economy; and  

(cid:190)  placing us at a competitive disadvantage compared to our competitors that have less debt or are less leveraged. 

Any of the above-listed factors could have an adverse effect on our business, results of operations, financial condition and 

our ability to meet our payment obligations under the Notes and our other debt. 

In addition, on each of October 1, 2011, 2016 and 2021, Notes holders may require us to purchase all or part of the Notes at 

100% of the principal amount at which time we may not have the available funds necessary to purchase the Notes. 

Restrictions in our credit facilities may limit our business and financial activities, including our ability to obtain additional capital 
in the future. 

On  November  25,  2009,  we  entered  into  a  Credit  Agreement  with  Bank  of  America,  N.A.,  as  modified  by  the  First 
Amendment to Credit Agreement dated as of July 16, 2010 and the Second Amendment to Credit Agreement dated as of November 
24, 2010, and certain agreements and instruments required by such Credit Agreement to secure a $10 million revolving credit facility 
and a $10 million uncommitted facility for our general corporate purposes. 

This  Credit  Agreement  contains  covenants  imposing  various  restrictions  on  our  business  and  financial  activities.    These 
restrictions may affect our ability to operate our business and undertake certain financial activities and may limit our ability to take 
advantage of potential business or financial opportunities as they arise. The restrictions these covenants place on us include limitations 
on  our  ability  to  incur  liens,  incur  indebtedness,  make  investments,  dissolve  or  merge  or  consolidate  with  or  into  another  entity, 
disposition  of  certain  property,  make  restricted  payments,  issue  or  sell  equity  interests,  engage  in  other  different  material  lines  of 
business, conduct related party transactions, enter into certain burdensome contractual obligations and use proceeds from any credit 
facility to purchase or carry margin stock or to extend credit to others for the same purpose.  The Credit Agreement also requires us to 
meet certain financial ratios, including a fixed charge coverage ratio and a quick ratio. 

Our  ability  to  comply  with  the  Credit  Agreement  may  be  affected  by  events  beyond  our  control,  including  prevailing 
economic, financial and industry conditions, and are subject to the risks stated in this section of the Annual Report.  The breach of any 
of these covenants or restrictions could result in a default under the Credit Agreement. An event of default under the Credit Agreement 
will permit Bank of America, N.A. to declare all amounts owed under such Credit Agreement to be immediately due and payable in 
full.  Acceleration of our other indebtedness may cause us to be unable to make interest payments for the credit facilities and repay the 
principal amount of the credit facilities. 

The  value of our  benefit plan assets  and liabilities  is  based on  estimates and assumptions,  which  may prove  inaccurate and  the 
actual amount of expenses recorded in the consolidated financial statements could differ materially from the assumptions used. 

Certain of our employees in the United Kingdom, Germany and Taiwan participate in Company sponsored defined benefit 
plans.  The  defined  benefit  plan  in  the  U.K  is  closed  to  new  entrants  and  is  frozen  with  respect  to  future  benefit  accruals.  The 

-21-
- 21 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
retirement benefit is based on the final average compensation and service of each eligible employee. In accounting for these plans, we 
are  required  to  make  actuarial  assumptions  that  are  used  to  calculate  the  earning  value  of  the  related  assets,  where  applicable,  and 
liabilities  and  the  amount  of  expenses  to  be  recorded  in  our  consolidated  financial  statements.  Assumptions  include  the  expected 
return on plan assets, discount rates, and mortality rates. While we believe the underlying assumptions under the projected unit credit 
method  are  appropriate,  the  carrying  value  of  the  related  assets  and  liabilities  and  the  actual  amount  of  expenses  recorded  in  the 
consolidated financial statements could differ materially from the assumptions used. 

Due to the recent fluctuations in the United Kingdom’s equity  markets and bond markets, changes in actuarial assumptions for 
our defined benefit plan could increase the volatility of the plan’s asset value, require us to increase cash contributions to the plan 
and have a negative impact on our results of operations and financial condition. 

The asset value of our defined benefit plan (the “plan”) has been volatile over the past year due primarily to wide fluctuations 
in  the  United  Kingdom’s  equity  markets  and  bond  markets.    The  plan  assets  consist  primarily  of  high  quality  corporate  bonds  and 
stocks traded on the London Stock Exchange and are determined from time to time based on their fair value, requiring us to utilize 
certain actuarial assumptions for the plan’s fair value determination. 

As of December 31, 2010, the benefit obligation of the plan was approximately $118.5 million and total assets in such plan 
were approximately $93.6 million.  Therefore, the plan was underfunded by approximately $24.9 million. The difference between plan 
obligations and assets, or the funded status of the plan, is a significant factor in determining the net periodic benefit costs of the plan 
and the ongoing funding requirements of the plan.  

Any fluctuations in the United Kingdom’s equity markets and bond markets or changes in several key actuarial assumptions, 
including, but not limited to, changes in discount rate, estimated return on the plan and mortality rates, can (i) affect the level of plan 
funding;  (ii)  cause  volatility  in  the  net  periodic  pension  cost;  and  (iii)  increase  our  future  funding  requirements.    In  the  event  that 
actual results differ from the actuarial assumptions or actuarial assumptions are changed, the funding status of the plan may change.  
Any deficiency in the funding of the plan could result in additional charges to equity and an increase in future plan expense and cash 
contribution.  A  significant  increase  in  our  funding  requirements  could  have  a  negative  impact  on  our  results  of  operations  and 
financial condition. 

In 2010, we established a joint venture to build a semiconductor facility in Chengdu, People’s Republic of China.  We are required 
to contribute at least $47.5 million to the joint venture during the first three years with additional contributions thereafter, as well 
as  a  substantial  amount  of  time  and  resources  to  establish  and  operate  the  joint  venture.    Any  failure  to  meet  any  such 
requirements, delays or unforeseen circumstances may cause us to incur penalties or require us to contribute additional expenses 
or  resources  and,  as  a  result,  could  have  an  adverse  effect  on  our  operating  efficiencies,  results  of  operations  and  financial 
conditions.    

Effective as of September 10, 2010, we entered into an Investment Cooperation Agreement and a Supplementary Agreement 
to the Investment Cooperation Agreement (collectively, the “CDHT Agreements”) with the Management Committee of the Chengdu 
Hi-Tech  Industrial  Development  Zone  (“CDHT”)  to  build  a  facility  in  Chengdu,  People’s  Republic  of  China,  with  a  Chinese  local 
partner, for  the  purpose of providing  surface  mounted  component production,  assembly  and  testing and  integrated  circuit  assembly 
and testing functions.  The CDHT Agreements require us to contribute substantial capital to the joint venture, including at least $47.5 
million in installments during the first three years, as well as time and resources to establish and operate the joint venture.  We must 
obtain various licenses, permissions, certifications and approvals, from time to time, related to the joint venture’s business operations.  
Any failure to meet any such requirements, delays or unforeseen circumstances may cause us to incur penalties, or require us to cease 
of operations, or contribute additional expenses and/or resources and as a result, could have a material adverse effect on our operating 
efficiencies, results of operations and financial conditions. 

Certain of our customers and suppliers require us to comply with their codes of conducts, which may include certain restrictions 
that may substantially increase the cost of our business as well as have an adverse effect on our operating efficiencies, results of 
operations and financial condition.   

Certain of our customers and suppliers require us to agree to comply with their codes of conduct, which may include detailed 
provisions  on  labor,  human  rights,  health  and  safety,  environment,  corporate  ethics  and  management  systems.    Certain  of  these 
provisions  are not requirements under  the  laws of  the  countries  in which we operate  and  may  be  burdensome  to  comply  with on a 
regular basis.  Moreover, new provisions may be added or material changes may be made to any these codes of conduct, and we will 
have to promptly implement  such new provisions or changes, which may substantially further increase the cost of our business, be 
burdensome to implement and adversely affect our operational efficiencies and results of operations.  If we violate any such code of 
conduct, we may lose further business with the customer or supplier and, in addition, we may be subject to fines from the customer or 
supplier.  While we believe that we are currently in compliance with our customers and suppliers' codes of conduct, there can be no 

-22-
- 22 - 

 
 
 
 
 
 
 
 
 
 
 
assurance that, from time to time, if any one of our customers and suppliers audits our compliance with its code of conduct, we would 
be found to be in full compliance.  A loss of business from these customers or suppliers could have a material adverse effect on our 
business, results of operations and financial conditions. 

There are risks associated with previous and future acquisitions.  We may ultimately not be successful in overcoming these risks or 
any other problems encountered in connection with acquisitions. 

The  risks  commonly  encountered  in  acquisitions  of  companies  include,  among  other  things,  higher  than  anticipated 
acquisition costs and expenses, the difficulty and expense of integrating the operations and personnel of the companies, the difficulty 
of bringing standards, procedures and controls into conformance with our operations, the ability to coordinate our new products and 
process  development,  the  ability  to  hire  additional  management  and  other  critical  personnel,  the  ability  to  increase  the  scope, 
geographic  diversity  and  complexity  of  our  operations,  difficulties  in  consolidating  facilities  and  transferring  processes  and  know-
how,  difficulties  in  reducing  costs,  prolonged  diversion  of  our  management’s  attention  from  the  management  of  our  business,  the 
ability  to  clearly  define  our  present  and  future  strategies,  the  loss  of  key  employees  and  customers  as  a  result  of  changes  in 
management and any geographic distances may make integration slower and more challenging. We may ultimately not be successful 
in overcoming these risks or any other problems encountered in connection with acquisitions. 

In  addition,  any  acquisition  may  cause  large  one-time  expenses  as  well  as  create  goodwill  and  other  intangible  assets  that 

may result in significant asset impairment charges in the future.  

If we fail to maintain an effective system of internal controls or discover material weaknesses in our internal control over financial 
reporting, we may not be able to report our financial results accurately or detect fraud, which could harm our business and the 
trading price of our Common Stock. 

Effective internal controls are necessary for us to produce reliable financial reports and are important in our effort to prevent 
financial  fraud.  We  are  required  to  periodically  evaluate  the  effectiveness  of  the  design  and  operation  of  our  internal  controls.    These 
evaluations may result in the conclusion that enhancements, modifications or changes to our internal controls are necessary or desirable.  
While  management  evaluates  the  effectiveness  of  our  internal  controls  on  a  regular  basis,  these  controls  may  not  always  be  effective.  
There are inherent limitations on the effectiveness of internal controls including collusion, management override, and failure of human 
judgment.    Because  of  this,  control  procedures  are  designed  to  reduce  rather  than  eliminate  business  risks.    If  we  fail  to  maintain  an 
effective system of internal controls or if management or our independent registered public accounting firm were to discover  material 
weaknesses  in  our  internal  controls,  we  may  be  unable  to  produce  reliable  financial  reports  or  prevent  fraud  which  could  harm  our 
financial condition and results of operations and result in loss of investor confidence and a decline in our stock price. 

Terrorist attacks, or threats or occurrences of other terrorist activities, whether in the United States or internationally, may affect 
the  markets  in  which  our  Common  Stock  trades,  the  markets  in  which  we  operate  and  our  results  of  operations  and  financial 
condition. 

Terrorist attacks, or threats or occurrences of other terrorist or related activities, whether in the United States or internationally, 
may affect the markets in which our Common Stock trades, the markets in which we operate and our profitability.  Future terrorist or 
related activities could affect our domestic and international sales, disrupt our supply chains and impair our ability to produce and deliver 
our products.  Such activities could affect our physical facilities or those of our suppliers or customers.  Such terrorist attacks could cause 
seaports or airports, to or through which we ship, to be shut down, thereby preventing the delivery of raw materials and finished goods to 
or  from  our  manufacturing  facilities  in  Shanghai,  China,  Neuhaus,  Germany  and  our  wafer  fabrication  facilities  near  Kansas  City, 
Missouri, or Manchester, England, or to our regional sales offices.  Due to the broad and uncertain effects that terrorist attacks have had 
on financial and economic markets generally, we cannot provide any estimate of how these activities might affect our future results of 
operations and financial condition.

RISKS RELATED TO OUR INTERNATIONAL OPERATIONS 

Our international operations subject us to risks that could adversely affect our operations. 

We expect net sales from foreign markets to continue to represent a significant portion of our total net sales.  In addition, the 
majority of our manufacturing facilities are located overseas in China.  In 2010, 2009 and 2008, net sales to customers outside the United 
States represented 78.0%, 82.7% and 80.2%, respectively, of our net sales.  There are risks inherent in doing business internationally, and 
any or all of the following factors could cause harm to our business: 

(cid:190)  changes  in,  or  impositions  of,  legislative  or  regulatory  requirements,  including  tax  laws  in  the  United  States  and  in  the 

countries in which we manufacture or sell our products; 

trade restrictions, transportation delays, work stoppages, and economic and political instability; 

(cid:190)  compliance with trade or other laws in a variety of jurisdictions; 
(cid:190) 
(cid:190)  changes in import/export regulations, tariffs and freight rates; 
(cid:190)  difficulties in collecting receivables and enforcing contracts; 
(cid:190)  currency exchange rate fluctuations; 
(cid:190) 
restrictions on the transfer of funds from foreign subsidiaries to the United States; 
(cid:190) 
the possibility of international conflict, particularly between or among China, Taiwan, England and the United States; 
(cid:190) 
legal regulatory, political and cultural differences among the countries in which we do business; 
(cid:190) 
longer customer payment terms; and 
(cid:190)  changes in U.S. or foreign tax regulations. 

We  have  significant  operations  and  assets  in  China,  Taiwan,  Hong  Kong  and  England  and,  as  a  result,  will  be  subject  to  risks 
inherent in doing business in those jurisdictions, which may adversely affect our financial performance. 

We  have  a  significant  portion  of  our  assets  in  mainland  China,  Taiwan,  Hong  Kong  and  England.    Our  ability  to  operate  in 
China, Taiwan, Hong Kong and England may be adversely affected by changes in those jurisdictions’ laws and regulations, including 
those relating to taxation, import and export tariffs, environmental regulations, land use rights, property and other matters.  In addition, 
our results of operations are subject to the economic and political situations.  We believe that our operations are in compliance with all 
applicable legal and regulatory requirements.  However, the central or local governments of these jurisdictions may impose new, stricter 
regulations  or  interpretations  of  existing  regulations  that  would  require  additional  expenditures  and  efforts  on  our  part  to  ensure  our 
compliance with such regulations or interpretations. 

Changes in the political environment or government policies in those jurisdictions could result in revisions to laws or regulations 
or their interpretation and enforcement, increased taxation, restrictions on imports, import duties or currency revaluations.  In addition, a 
significant destabilization of relations between or among China, Taiwan, Hong Kong or England and the United States could result in 
restrictions or prohibitions on our operations or the sale of our products or the forfeiture of our assets in these jurisdictions.  There can be 
no certainty as to the application of the laws and regulations of these jurisdictions in particular instances.  Enforcement of existing laws or 
agreements  may  be  sporadic  and  implementation  and  interpretation  of  laws  inconsistent.    Moreover,  there  is  a  high  degree  of 
fragmentation among regulatory authorities, resulting in uncertainties as to which authorities have jurisdiction over particular parties or 
transactions.  The possibility of political conflict between these countries or with the United States could have an adverse impact upon our 
ability to transact business in these jurisdictions and to generate profits. 

A slowdown in the Chinese economy could limit the growth in demand for electronic devices containing our products, which would 
have a material adverse effect on our business, results of operations and prospects. 

We  believe  that  an  increase in  demand  in China  for  electronic  devices  that  include our products will  be  an  important  factor  in our 
future growth.   Although the Chinese economy has grown significantly in recent years, there can be no assurance that such growth 
will  continue.    Any  weakness  in  the  Chinese  economy  could  result  in  a  decrease  in  demand  for  electronic  devices  containing  our 
products and, thereby, materially and adversely affect our business, results of operations and prospects. 

Economic regulation in China could materially and adversely affect our business, results of operations and prospects. 

We have a significant portion of our manufacturing capacity in China.  In addition, in 2010 30.6% of our total sales were billed to 
customers in China.  In recent years, the Chinese economy has experienced periods of rapid expansion and wide fluctuations in the 
rate of inflation.  In response to these factors, the Chinese government has, from time to time, adopted measures to regulate growth 
and contain inflation, including measures designed to restrict credit or control prices.  Such actions in the future could increase the 
cost of doing business in China or decrease the demand for our products in China and, thereby, have a material adverse effect on our 
business, results of operations and prospects.

We  could  be  adversely  affected  by  violations  of  the  United  States’  Foreign  Corrupt  Practices  Act  and  similar  worldwide  anti-
bribery laws. 

              The  United  States’  Foreign  Corrupt  Practices  Act  (“FCPA”)  and  similar  anti-bribery  laws  in  other  jurisdictions  generally 
prohibit companies and their intermediaries from making improper payments to government officials for the purpose of obtaining or 
retaining business. Our policies  mandate compliance with these anti-bribery laws. We operate in many parts of the world that may 
have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may 
conflict  with  local  customs  and  practices.  We  train  our  staff  concerning  FCPA  and  related  anti-bribery  laws.  We  have  established 
procedures  and  controls  to  monitor  internal  and  external  compliance.  There  can  be  no  assurance  that  our  internal  controls  and 
procedures always will protect us from reckless or criminal acts committed by our employees or agents. If we are found to be liable 
for FCPA violations (either due to our own acts or inadvertence, or due to the acts or inadvertence of others), we could incur criminal 
or civil penalties or other sanctions, which could have a material adverse effect on our business. 

We are subject to foreign currency risk as a result of our international operations. 

We face exposure to adverse movements in foreign currency exchange rates, principally the Chinese Yuan, the Taiwanese 
dollar and the British Pound Sterling and, to a lesser extent, the Japanese Yen, the Euro and the Hong Kong dollar.  Our income and 
expenses are based on a mix of currencies and a decline in one  currency relative to the other currencies could adversely affect our 
results of operations.  Furthermore, our results of operations are reported in U.S. dollars, which is our reporting currency.  In the event 
the U.S. dollar weakens against a foreign currency, we will experience a currency transaction loss, which could adversely affect our 
results  of  operations.    Also,  fluctuations  in  foreign  currency  exchange  rates  may  have  an  adverse  impact  and  be  increasingly 
influential to our overall sales, profits and results of operations as amounts that are measured in foreign currency are translated back to 
U. S. dollars for reporting purposes.  Our foreign currency risk may change over time as the level of activity in foreign markets grows 
and could have an adverse impact upon our financial results, especially as the portion of our sales attributable to Europe increases.  
We do not usually employ hedging techniques designed to mitigate foreign currency exposures and, therefore, we could experience 
currency losses as these currencies fluctuate against the U.S. dollar. 

The People’s Republic of China is experiencing rapid social, political and economic change, which has increased labor 
costs and other related costs that could make doing business in China less advantageous than in prior years.  Increased labor costs 
in China could adversely affect our business, results of operations and financial condition.  

Historically, labor in China has been readily available at a lower cost compared to other countries, and any increase in labor 
cost in China has been consistent with the projected annual increase in the inflation index and the amount of past labor cost increases. 
However,  because  China  is  experiencing  rapid  social,  political  and  economic  change,  there  can  be  no  assurance  that  labor  will 
continue to be available in China at costs consistent with historical levels. Any future increase in labor cost in China is likely to be 
higher than historical and projected amounts and may occur multiple times in any given year.  As a result of experiencing such rapid 
social,  political  and  economic  change,  China  is  also  likely  to  enact  new,  and/or  revise  its  existing,  labor  laws  and  regulations  on 
employee compensation and benefits.  These changes in Chinese labor laws and regulations will likely to have an adverse effect on 
product manufacturing costs in China. Furthermore, if China workers go on strike to demand higher wages, our operations could be 
disrupted.  Many of our suppliers are currently dealing with labor shortages in China, which may result in future supply delays and 
disruptions and may drive a substantial increase in their labor costs that is likely to be shared by us in the form of price increases to us. 
New or revised  government  labor  laws  or  regulations,  strikes  or labor  shortages  could  cause  our product  costs  to  rise  and/or  could 
cause manufacturing partners on whom we rely to exit the business. These events could have a material adverse impact on our product 
availability and quality, which would affect our business, results of operations and financial condition. 

We may not continue to receive preferential tax treatment in Asia, thereby increasing our income tax expense and reducing our net 
income. 

As an incentive for establishing our manufacturing subsidiaries in China, we received preferential tax treatment.  In addition, in 
conjunction with the acquisition of Anachip, we also receive preferential tax treatment in Taiwan.  Governmental changes in foreign tax 
law may cause us not to be able to continue receiving these preferential tax treatments in the future, which may cause an increase in our 
income tax expense, thereby reducing our net income.

The distribution of any earnings of our foreign subsidiaries to the United States may be subject to U.S. income taxes, thus reducing 
our net income. 

With  the  establishment  of  our  holding  companies  in  2007,  we  intend  to  permanently  reinvest  overseas  all  earnings  from 
foreign subsidiaries.  Although we intend to permanently reinvest overseas all earnings, certain unusual circumstances may require us 
to  repatriate  funds.    This  was  the  case  during  the  first  quarter  of  2009,  in  which  we  repatriated  approximately  $28.5  million  of 
accumulated earnings from one of our Chinese subsidiaries, resulting in additional non-cash federal and state income tax expense of 
approximately $5.3 million. 

As  of  December  31,  2010,  accumulated  and  undistributed  earnings  of  our  subsidiaries  in  China  were  approximately  $146 

million, which we consider as a permanent investment. 

As  of  December  31,  2010,  we  have  undistributed  earnings  from  non-U.S.  operations  of  approximately  $254  million 
(including  approximately  $27  million  of  restricted  earnings,  which  are  not  available  for  dividends).    Additional  federal  and  state 
income taxes of approximately $44 million would be required should such earnings be repatriated to the U.S.  

We may, in the future, plan to distribute earnings of our foreign subsidiaries to the U.S.  We may be required to pay U.S. income 
taxes on these earnings to the extent we have not previously recorded deferred U.S. taxes on such earnings. Any such taxes would reduce 
our net income in the period in which these earnings are distributed. 

RISKS RELATED TO OUR COMMON STOCK 

Variations in our quarterly operating results may cause our stock price to be volatile. 

We have experienced substantial variations in net sales, gross profit margin and operating results from quarter to quarter.  We 

believe that the factors that influence this variability of quarterly results include: 

the timing of our and our competitors’ new product introductions; 

(cid:190)  strength of the global economy and the stability of the financial markets; 
(cid:190)  general economic conditions in the countries where we sell our products; 
(cid:190)  seasonality and variability in the computing and communications market and our other end-markets; 
(cid:190) 
(cid:190)  product obsolescence; 
(cid:190) 
(cid:190) 
(cid:190)  our ability to develop new process technologies and achieve volume production at our fabrication facilities; 
(cid:190)  changes in manufacturing yields; 
(cid:190)  adverse movements in exchange rates, interest rates or tax rates; and 
(cid:190) 

the scheduling, rescheduling and cancellation of large orders by our customers; 
the cyclical nature of demand for our customers’ products; 

the availability of adequate supply commitments from our outside suppliers or subcontractors. 

Accordingly, a comparison of our results of operations from period to period is not necessarily meaningful to investors and our 
results of operations for any period do not necessarily indicate future performance.  Variations in our quarterly results may trigger volatile 
changes in our stock price. 

We may enter into future acquisitions and take certain actions in connection with such acquisitions that could adversely affect the 
price of our Common Stock. 

As part of our growth strategy, we expect to review acquisition prospects that would implement our vertical integration strategy 
or offer other growth opportunities.  While we do not currently have any agreements or commitments in place with respect to any material 
acquisitions, we are in various stages of preliminary discussions, and we may acquire businesses, products or technologies in the future.  
In the event of future acquisitions, we could: 

(cid:190)  use a significant portion of our available cash; 
(cid:190) 
(cid:190) 
(cid:190) 
(cid:190) 
(cid:190) 

issue equity securities, which would dilute current stockholders’ percentage ownership; 
incur substantial debt; 
incur or assume contingent liabilities, known or unknown; 
incur amortization expenses related to intangibles; and 
incur large, immediate accounting write-offs.

Such actions by us could harm our results from operations and adversely affect the price of our Common Stock. 

Our directors, executive officers and significant stockholders hold a substantial portion of our Common Stock, which may lead to 
conflicts with other stockholders over corporate transactions and other corporate matters. 

Our  directors,  executive  officers  and  our  affiliate,  LSC,  beneficially  own  approximately  26.6%  of  our  outstanding  Common 
Stock,  including  options  to  purchase  shares  of  our  Common  Stock  that  are  exercisable  within  60 days  of  December 31,  2010.    These 
stockholders, acting together, will be able to influence significantly all matters requiring stockholder approval, including the election of 
directors and significant corporate transactions such as mergers or other business combinations.  This control may delay, deter or prevent 
a third party from acquiring or merging with us, which could adversely affect the market price of our Common Stock. 

LSC, our largest stockholder, owns approximately 18.7% (approximately 8.4 million shares) of our Common Stock.  Some of 
our directors and executive officers may have potential conflicts of interest because of their positions with LSC or their ownership of LSC 
common  stock.    Some  of  our  directors  are  LSC  directors  and  officers,  and  the  non-employee  Chairman  of  our  Board  of  Directors  is 
Chairman  of  the  Board  of  LSC.    L.P.  Hsu,  a  member  of  the  Board  of  Directors  since  2007,  serves  as  a  consultant  to  Lite-On 
Technology Corporation.  Several of our directors and executive  officers own LSC common stock and hold options to purchase LSC 
common  stock.    Service  on  our  Board  of  Directors  and  as  a  director  or  officer  of  LSC,  or  ownership  of  LSC  common  stock  by  our 
directors and executive officers, could create, or appear to create, actual or potential conflicts of interest when directors and officers are 
faced with decisions that could have different implications for LSC and us.  For example, potential conflicts could arise in connection 
with decisions involving the Common Stock owned by LSC, or under the other agreements we may enter into with LSC. LSC was our 
largest external supplier of discrete semiconductor products for subsequent sale by us.  In 2010, 2009 and 2008, LSC accounted for 1.1%, 
2.1% and 3.5%, respectively, of our net sales.  Also, in 2010, 2009 and 2008, approximately 6.9%, 6.3% and 9.6%, respectively, of our 
net sales were from products manufactured by LSC.   

We may have difficulty resolving any potential conflicts of interest with LSC, and even if we do, the resolution may be less 

favorable than if we were dealing with an unrelated third party. 

We  were  formed  in  1959,  and  our  early  corporate  records  are  incomplete.  As  a  result,  we  may  have  difficulty  in  assessing  and 
defending  against  claims  relating  to  rights  to  our  Common  Stock  purporting  to  arise  during  periods  for  which  our  records  are 
incomplete. 

We were formed in 1959 under the laws of California and reincorporated in Delaware in 1968. We have had several transfer 
agents over the past 50 years.  In addition, our early corporate records, including our stock ledger, are incomplete. As a result, we may 
have difficulty in assessing and defending against claims relating to rights to our Common Stock purporting to arise during periods for 
which our records are incomplete. 

Conversion of our convertible senior notes will dilute the ownership interest of existing stockholders, including stockholders who 
had previously converted their notes. 

To the extent we issue Common Stock upon conversion of the Notes, the conversion of some or all of the Notes will dilute 
the ownership interests of existing stockholders, including stockholders who have received Common Stock upon prior conversion of 
the  Notes.  Any  sales  in  the  public  market  of  the  Common  Stock  issuable  upon  such  conversion  could  adversely  affect  prevailing 
market  prices  of  our  Common  Stock.  In  addition,  the  existence  of  the  Notes  may  encourage  short  selling  by  market  participants 
because the conversion of the Notes could depress the price of our Common Stock. 

Non-cash tender offers, debt equity swaps or equity exchanges to consummate our business activities are likely to have the effect of 
diluting the ownership interest of existing stockholders, including qualified stockholders who receive shares of our Common Stock 
in such business activities.  

We,  from  time  to  time,  may  utilize  non-cash  tender  offers,  debt  equity  swaps  or  equity  exchanges  in  accordance  with  the 
guidance  and  rules  promulgated  by  the  United  States  Securities  and  Exchange  Commission  to  consummate  our  business  activities.  
Such  means  to  consummate  our  business  activities  will  likely  involve  issuance  of  our  Common  Stock  in  large  quantities  and  will 
subsequently  dilute  the  ownership  interest  of  existing  stockholders,  including  stockholders  who  previously  received  shares  of  our 
Common Stock in such business activities.  Any sales in the public market of the newly issued Common Stock could adversely affect 
prevailing market prices of our Common Stock.  In addition, utilizing non-cash tender offers, debt equity swaps or equity exchanges 
as means to consummate our business activities may encourage short selling because such utilization could depress the price of our 
Common Stock.

The  repurchase  rights  and  the  increased  conversion  rate  triggered  by  a  make-whole  fundamental  change  could  discourage  a 
potential acquirer.  

If  a  “fundamental  change”  in  accordance  with  the  terms  of  the  senior  convertible  notes  were  to  occur,  the  holders  of  the 
Notes have the right to require us to repurchase the Notes.  A fundamental change would include a change in control of the Company.  
In addition, if a make-whole fundamental change were to occur, which may include an acquisition of the Company, the conversion 
rate for the senior convertible notes will increase.  The repurchase rights in our senior convertible notes triggered by a fundamental 
change and the increased conversion rate triggered by a make-whole fundamental change could discourage a potential acquirer. 

Anti-takeover effects of certain provisions of Delaware law and our Certificate of Incorporation and Bylaws, may hinder a take-
over attempt. 

Some provisions of Delaware law, our certificate of incorporation and bylaws may be deemed to have an anti-takeover effect 
and may delay or prevent a tender offer or takeover attempt, including those attempts that might result in a premium over the market 
price for the shares held by stockholders. 

Section 203 of Delaware General Corporation Law may deter a take-over attempt.  

Section 203  of  the  Delaware  General  Corporation  Law  prohibits  transactions  between  a  Delaware  corporation  and  an 
“interested stockholder,” which is defined as a person who, together with any affiliates or associates, beneficially owns, directly or 
indirectly,  15.0%  or  more  of  the  outstanding  voting  shares  of  a  Delaware  corporation.  This  provision  prohibits  certain  business 
combinations between an interested stockholder and a Delaware corporation for a period of three years after the date the stockholder 
becomes an interested stockholder, unless: 

(i) 

(ii) 

either  the  business  combination  or  the  transaction  which  resulted  in  the  stockholder  becoming  an  interested 
stockholder is approved by the corporation’s board of directors prior to the date the interested stockholder becomes 
an interested stockholder; 

the interested stockholder acquired at least 85.0% of the voting stock of the corporation (other than stock held by 
directors  who  are  also  officers  or  by  certain  employee  stock  plans)  in  the  transaction  in  which  the  stockholder 
became an interested stockholder; or 

(iii) 

the business combination is approved by a majority of the board of directors and by the affirmative vote of 66.66% 
of the outstanding voting stock that is not owned by the interested stockholder. 

For  this  purpose,  business  combinations  include  mergers,  consolidations,  sales  or  other  dispositions  of  assets  having  an 
aggregate value in excess of 10.0% of the aggregate market value of the consolidated assets or outstanding stock of the corporation, 
and certain transactions that would increase the interested stockholder’s proportionate share ownership in the corporation. 

Certificate of Incorporation and Bylaw Provisions may deter a take-over attempt. 

Provisions of our certificate of incorporation and bylaws may have the effect of making it more difficult for a third party to 
acquire  control  of  our  Company.  In  particular,  our  certificate  of  incorporation  authorizes  our  Board  of  Directors  to  issue,  without 
further  action  by  the  stockholders,  up  to  1,000,000 shares  of  preferred  stock  with  rights  and  preferences,  including  voting  rights, 
designated from time to time by the Board of Directors. The existence of authorized but unissued shares of preferred stock enables our 
Board of Directors to render it more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, 
proxy contest or otherwise.

Dividends 

We  have  never  declared  or  paid  cash  dividends  on  our  Common  Stock,  and  currently  do  not  intend  to  pay  dividends  in  the 
foreseeable future as we intend to retain any earnings for use in our business. Our credit agreement with Bank of America permits us to 
pay dividends to our stockholders so long as we are not in default and are in continuing operation at  the time of such dividend.  The 
payment of dividends is within the discretion of our Board of Directors, and will depend upon, among other things, our earnings, financial 
condition, capital requirements, and general business conditions. There have been no repurchases of Common Stock in our history.

Performance Graph 

Set  forth  below  is  a  line  graph  comparing  the  yearly  percentage  change  in  the  cumulative  total  stockholder  return  of  our 
Common Stock against the cumulative total return of the Nasdaq Composite and the Nasdaq Industrial Index for the five calendar years 
ending December 31, 2010.  The graph is not necessarily indicative of future price performance.   

The  graph  shall  not  be  deemed  incorporated  by  reference  by  any  general  statement  incorporating  by  reference  this  Annual 
Report  into  any  filing  under  the  Securities  Act  of  1933  or  under  the  Securities  Exchange  Act  of  1934,  except  to  the  extent  that  the 
Company specifically incorporates this information by reference, and shall not otherwise be deemed filed under such Acts.

The graph assumes $100 invested on December 31, 2005 in our Common Stock, the stock of the companies in the Nasdaq 
Composite  Index  and  the  Nasdaq  Industrial  Index,  and  that  all  dividends  received  within  a  quarter,  if  any,  were  reinvested  in  that 
quarter. 

Issuer Purchases of Equity Securities 

We  may  from  time  to  time  seek  to  repurchase  our  outstanding  Notes  or  Common  Stock  in  the  open  market,  in  privately 
negotiated  transactions  or  otherwise.    Such  repurchases,  if  any,  will  depend  on  prevailing  market  conditions,  our  liquidity 
requirements, contractual restrictions and other factors.  The amounts involved may be material. 

There have been no repurchases of our Notes or Common Stock during the fourth quarter of 2010.

Management’s Discussion and Analysis of Financial Condition and Results of Operations 

The  following  section  discusses  managements  view  of  the    financial  condition,  results  of  operations  and  cash  flows  of   
Diodes Incorporated and its subsidiaries (collectively, “the Company,” “our Company,” “we,” “our,” “ours,” or “us”) and should be 
read  together  with  the  consolidated  financial  statements  and  the  notes  to  consolidated  financial  statements  included  elsewhere  in  this 
Form 10-K. 

The  following  discussion  contains  forward-looking  statements  and  information  relating  to  our  Company.  We  generally 
identify forward-looking statements by the use of terminology such as “may,” “will,” “could,” “should,” “potential,” “continue,” 
“expect,” “intend,” “plan,” “estimate,” “anticipate,” “believe,” “project,” or similar phrases or the negatives of such terms. We 
base these statements on our beliefs as well as assumptions we made using information currently available to us. Such statements are 
subject to risks, uncertainties and assumptions, including those identified in "Part I, Item 1A. Risk Factors,” as well as other matters 
not  yet  known  to  us  or  not  currently  considered  material  by  us.  Should  one  or  more  of  these  risks  or  uncertainties  materialize,  or 
should  underlying  assumptions  prove  incorrect,  actual  results  may  vary  materially  from  those  anticipated,  estimated  or  projected. 
Given  these  risks  and  uncertainties,  prospective  investors  are  cautioned  not  to  place  undue  reliance  on  such  forward-looking 
statements. Forward-looking statements do not guarantee future performance and should not be considered as statements of fact. 

You should not unduly rely on these forward-looking statements, which speak only as of the date of this Annual Report on 
Form 10-K. Unless required by law, we undertake no obligation to publicly update or revise any forward-looking statements to reflect 
new  information  or  future  events  or  otherwise.    The  Private  Securities  Litigation  Reform  Act  of  1995  (the  “Act”)  provides  certain 
“safe harbor” provisions for forward-looking statements.  All forward-looking statements made in this Annual Report on Form 10-K 
are made pursuant to the Act.

(cid:190)  On  June  30,  2010,  we  put  our  auction  rate  securities  (“ARS”)  back  to  UBS  AG  at  par  value  pursuant  to  the  previously 
disclosed settlement agreement, which liquidated our ARS for cash, and used the proceeds to pay off the “no net cost” loan. 

Business Outlook 

For  2011,  we  look  to  continue  to  enhance  our  position  as  a  leading  global  manufacturer  and  supplier  of  high-quality 
semiconductor products, and to continue to add other complementary product lines, such as power management and logic products, 
using our packaging technology capability.  In addition, in 2011 we expect to see continued improvements in demand and order rates 
over 2010, increased production ramps of previous design wins at new customers and the introduction of new product applications for 
existing  customers.  We  expect  our  business  to  continue  to  benefit  from  the  increasing  demand  in  China,  as  we  consider  the  China 
market a major growth driver for our business.  We expect all our manufacturing facilities to maintain full utilization, except in the 
first quarter of 2011 for our China operations where equipment  utilization will be impacted by China labor shortages in the coastal 
region and fewer working days and the Chinese New Year Holiday in February.  The success of our business depends, among other 
factors, on the strength of the global economy and the stability of the financial markets, which in turn affect our customers’ demand 
for our products, the ability  of our customers to meet their payment obligations, the likelihood of customers canceling or deferring 
existing orders and end-user consumers’ demand for items containing our products in the end-markets we serve. We believe the long-
term outlook for our business remains generally favorable despite the recent volatility in the global economy and the equity and credit 
markets  as  we  continue  to  execute  on  the  strategy  that  has  proven  successful  for  us  over  the  years.  Although  the  current  economy 
creates a more challenging environment for all businesses, we believe the decisive measures taken in response to the global economic 
downturn  have  properly  positioned  us  for  our  recent  return  to  a  profitable  growth  model  and  that  over  the  long-term  we  are  well 
positioned for future growth.  See “Risk Factors – The success of our business depends on the strength of the global economy and the 
stability of the financial markets, and any weaknesses in these areas may have a material adverse effect on our revenues, results of 
operations and financial condition.” in Part I, Item 1A of this Annual Report for additional information.

Overview 

During  the  first  three  quarters  of  2010,  we  saw  an  increase  in  our  net  sales  due  to  strong  demand  for  our  products  in  all 
geographic regions led by North America and Europe.  In addition, during the first, second and third quarters of 2010, gross profit 
margin increased due to improved product mix in North America and Europe, which includes a favorable mix of higher margin new 
products, as well as increased capacity at our wafer fabrication facilities and generally stable average selling prices (“ASP”).  During 
the fourth quarter of 2010, our business continued to benefit from continued ramp-up of prior design wins and customer acceptance of 
our new product portfolio.   

As described in “Business – Our Strategy” in Part I, Item 1 of this Annual Report, the principal elements of our strategy include 

the following: 

(cid:190)  Continue to rapidly introduce innovative discrete, logic and analog semiconductor products; 
(cid:190)  Expand our available market opportunities; 
(cid:190)  Maintain intense customer focus; 
(cid:190)  Enhance cost competitiveness; and 
(cid:190)  Pursue selective strategic acquisitions. 

In  implementing  this  strategy,  the  following  factors  have  affected,  and,  we  believe,  will  continue  to  affect,  our  results  of 

operations: 

(cid:190)  For  2010,  we  have  seen  increased  demand  for  our  products  as  compared  to  2009.  We  have  experienced  pressure  from  our 
customers  and  competitors  to  reduce  the  selling  price  for  our  standard  products,  and  we  expect  future  improvements  in  net 
income  to  result  primarily  from  increases  in  sales  volume  and  improvements  in  product  mix  as  well  as  manufacturing  cost 
reductions  in  order  to  offset  any  reduced  ASP  of  our  products.    See  “Risk  Factors  –  We  are  and  will  continue  to  be  under 
continuous pressure from our customers and competitors to reduce the price of our products, which could adversely affect our 
growth and profit margins” in Part I, Item 1A of this Annual Report for additional information. 

(cid:190)  For  the  years  ended  December  31,  2010,  2009  and  2008,  our  original  equipment  manufacturers  (“OEM”)  and  electronic 
manufacturing services (“EMS”) customers together accounted for 46.1%, 53.0% and 55.9% of net sales, respectively, while our 
global network of distributors accounted for 53.9%, 47.0% and 44.1% of net sales, respectively. 

(cid:190)  Our gross profit margin was 36.7% in 2010, compared to 27.9% in 2009 and 30.6% in 2008.  Our gross profit margin increase in 
2010  was  primarily  due  to  improved  product  mix,  increased  operating  efficiencies  and  higher  capacity  utilization  at  our 
manufacturing and wafer fabrication facilities.  Our model rate is 35% as we strive to improve our gross margins in support of 
our  profitable  growth  strategy.    Future  gross  profit  margins  will  depend  primarily  on  our  product  mix,  manufacturing  cost 
savings, and the demand for our products.   

(cid:190)  For 2010, the percentage of our net sales derived from our Asian subsidiaries was 72.5%, compared to 76.8% in 2009 and 74.2% 
in 2008. We expect our net sales to the Asian market to decrease  as a percentage of our total net sales as we continue to see 
increased demand for our products in North America and Europe. 

(cid:190)  As  a  result  of  the  Zetex  acquisition  in  2008,  we  have  added  significant  revenue  in  Europe.    As  such,  Europe  accounted  for 

approximately 12.1%, 10.4% and 10.0% of our net sales in 2010, 2009 and 2008, respectively. 

(cid:190)  As of December 31, 2010, we had invested approximately $283.5 million in our manufacturing facilities in China.  During 2010, 
we  invested  approximately  $68.5 million  in  these  manufacturing  facilities,  and  we  expect  to  continue  to  invest  in  our 
manufacturing facilities, although the amount to be invested will depend on product demand and new product developments. 

(cid:190)  For 2010, our capital expenditures were approximately 14.1% of our net sales, which is an increase from our historical 10% to 
12% model of net sales model as we increased capacity due to increased demand and lower capital expenditure during 2009 due 
to the global economic downturn.  For 2011, we intend to resume capital expenditures to their normal range of 10% to 12% of 
net sales. 

(cid:190)  We  increased  our  investment  in  research  and  development  from  $23.8 million  in  2009  to  $26.6 million  in  2010.    In  2010, 

research and development expenses were approximately 4.3% of net sales.

Convertible Senior Notes 

On October 12, 2006, we issued and sold convertible senior notes with an aggregate principal amount of $230 million due 2026 
(the “Notes”), which pay 2.25% interest per annum on the principal amount of the Notes, payable semi-annually in arrears on April 1 and 
October 1 of each year, beginning on April 1, 2007.  See Notes 1 and 10 of “Notes to Consolidated Financial Statements” of this Annual 
Report for additional information. 

Recent Changes to Operations 

During 2010, we announced an investment agreement with the Management Committee of the Chengdu Hi-Tech Industrial 
Development Zone (the “CDHT”).  Under this agreement, we have agreed to form a joint venture with a Chinese partner, Chengdu Ya 
Guang  Electronic  Company  Limited,  to  establish  a  semiconductor  manufacturing  facility  for  the  purpose  of  providing  surface 
mounted component production, assembly and testing, and integrated circuit assembly and testing in Chengdu, People’s Republic of 
China.  We initially will own at least 95% of the joint venture.  The manufacturing facility will be developed in phases over a ten year 
period, and we are expected to contribute at least $47.5 million to the joint venture in installments during the first three years.  The 
CDHT will grant the joint venture a fifty year land lease, provide temporary facilities for up to three years at a subsidized rent while 
the joint venture builds the manufacturing facility and provide corporate and employee tax incentives, tax refunds, subsidies and other 
financial support to the joint venture and its qualified employees.  If the joint venture fails to achieve specified levels of investment, 
the investment agreement allows for a renegotiation as well as the option to repay a portion of such financial support.  This is a long-
term, multi-year project that will provide additional capacity once we have reached the maximum production capacity at our Shanghai 
facilities in the next few years.  

Description of Sales and Expenses 

Net sales 

The principal factors that have affected or could affect our net sales from period to period are: 

(cid:190)  The condition of the economy in general and of the semiconductor industry in particular, 
(cid:190)  Our customers’ adjustments in their order levels, 
(cid:190)  Changes in our pricing policies or the pricing policies of our competitors or suppliers, 
(cid:190)  The addition or termination of key supplier relationships, 
(cid:190)  The rate of introduction and acceptance by our customers of new products, 
(cid:190)  Our ability to compete effectively with our current and future competitors, 
(cid:190)  Our ability to enter into and renew key corporate and strategic relationships with our customers, vendors and strategic alliances, 
(cid:190)  Changes in foreign currency exchange rates, 
(cid:190)  A major disruption of our information technology infrastructure, 
(cid:190)  Unforeseen catastrophic events, such as armed conflict, terrorism, fires, typhoons and earthquakes, and 
(cid:190)  Any other disruptions, such as labor shortages, unplanned maintenance or other manufacturing problems. 

Cost of goods sold 

Cost of goods sold includes manufacturing costs for our semiconductors and our wafers.  These costs include raw materials used 
in  our  manufacturing  processes  as  well  as  the  labor  costs  and  overhead  expenses.    Cost  of  goods  sold  is  also  impacted  by  yield 
improvements, capacity utilization and manufacturing efficiencies.  In addition, cost of goods sold includes the cost of products that we 
purchase  from  other  manufacturers  and  sell  to  our  customers.    Cost  of  goods  sold  is  also  affected  by  inventory  obsolescence  if  our 
inventory management is not efficient. 

Selling, general and administrative expenses 

Selling, general and administrative expenses relate primarily to compensation and associated expenses for personnel in general 
management, sales and marketing, information technology, engineering, human resources, procurement, planning and finance, and sales 
commissions, as well as outside legal, accounting and consulting expenses, and other operating expenses.   

Research and development expenses 

Research  and  development  expenses  consist  of  compensation  and  associated  costs  of  employees  engaged  in  research  and 
development  projects,  as  well  as  materials  and  equipment  used  for  these  projects.    Research  and  development  expenses  are  primarily

associated  with  our  wafer  facilities  near  Kansas  City,  Missouri  and  Manchester,  United  Kingdom  and  our  manufacturing  facilities  in 
China, as well as with our engineers in the U.S. and Taiwan.  All research and development expenses are expensed as incurred.   

Amortization of acquisition- related intangible assets 

Amortization  of  acquisition-related  intangible  assets  consists  of  amortization  of  acquisition-related  intangible  assets,  such  as 

developed technologies and customer relationships.   

Interest income / expense 

Interest income consists of interest earned on our cash and investment balances.  Interest expense consists of interest payable 

on our outstanding credit facilities, “no net cost” loan and other debt instruments including the stated rate on our Notes.   

Amortization of debt discount 

Amortization of debt discount consists of non-cash amortization expense related to our Notes. 

Income tax provision 

Our  global  presence  requires  us  to  pay  income  taxes  in  a  number  of  jurisdictions.  See  Note15  of  “Notes  to  Consolidated 

Financial Statements” for additional information.

Cost of goods sold increased $74.9 million, or 23.9%, for 2010 to $388.0 million, compared to $313.2 million for 2009.  As a 
percent  of  sales,  cost of goods  sold decreased  from  72.1%  for  2009  to  63.3% for 2010.    Our  average  unit  cost  (“AUP”) decreased 
approximately  7.7%.  The  decrease  in  cost  of  goods  sold  as  a  percentage  of  net  sales  and  the  decrease  in  AUP  was  due  to  higher 
capacity utilization in our manufacturing operations.   

 Gross profit for 2010 increased 85.5% to $224.9 million from $121.2 million for 2009.  Gross profit as a percentage of net 
sales was 36.7% for 2010, compared to 27.9% for 2009. The increased gross margin was primarily due to higher capacity utilization 
of our manufacturing and wafer fabrication facilities, increased operating efficiencies and improved product mix. 

Selling, general and administrative ("SG&A")

$ 

SG&A for 2010 increased $18.4 million, or 26.1%, to $88.8 million, compared to $70.4 million for 2009, due primarily to 
higher  sales  commissions  related  to  increased  sales,  as  well  as  to  higher  employee  related  costs  including  incentives  and  higher 
general operating costs.  SG&A, as a percentage of net sales, was 14.5% in 2010, compared to 16.2% in 2009.

$ 

2009  
 4,871  

$ 

Interest income for 2010 decreased to $2.8 million, compared to $4.9 million for 2009, due primarily to a decrease in interest 

income earned on our ARS, which were put back to UBS at par value on June 30, 2010 in accordance with the settlement agreement. 

Interest expense 

2010

2009  
 7,471  

$ 

$ 

Interest expense for 2010 was $5.2 million, compared to $7.5 million for 2009. The $2.3 million decrease is due primarily to 
the reduced interest paid due to the repurchase and retirement of $95.7 million par value of Notes since the fourth quarter of 2008 and 
our “no net cost” loan being paid off on June 30, 2010 in connection with the settlement agreement with UBS. 

Amortization of debt discount 

2010

$ 

$ 

Amortization of debt discount for 2010 was $7.7 million, compared to $8.3 million for 2009. The $0.6 million decrease in 
amortization of debt discount was due primarily to the repurchase and retirement of $95.7 million par value of Notes since the fourth 
quarter of 2008. 

Other income (expense) 

2010 
 3,214  

$ 

2009  
 (777) 

$ 

Other income for 2010 was $3.2 million, compared to other expense of $0.8 million for 2009. Included in other income for 
2010 was a $1.7 million gain on sale of non−core intellectual property for which no intangible assets were recorded and a $1.1 million 
gain on forgiveness of debt from government subsidies in China. Included in other expense for 2009 was foreign currency losses  of 
$4.7 million, partially offset by a $1.4 million gain on forgiveness of debt from government subsidies in China and a $1.2 million gain 
on extinguishment of debt. 

Income tax provision 

2010 
 17,839  

$ 

2009  
 1,302  

$ 

We  recognized  income  tax  expense  of  $17.8  million  for  2010,  resulting  in  an  effective  tax  rate  of  18.2%,  as  compared  to 
11.7% for 2009.  Our effective tax rate compared with the same period last year was higher as it was impacted by additional income in 
higher-taxed jurisdictions.  This was partially offset by provision-to-return adjustments and the non-cash tax benefit from reversing 
valuation allowances on deferred tax assets from U.S. and U.K. loss carryforwards.  In 2009, the effective tax rate was impacted by 
the  non-cash  income  tax  expense  of  approximately  $7.5  million  associated  with  repatriating  earnings  of  foreign  subsidiaries  to the 
U.S. parent.  This was partially offset by provision-to-return adjustments recorded in 2009.

Net income attributable to common stockholders increased 927.9% to $76.7 million (or $1.74 basic earnings per share and 
$1.68 diluted earnings per share) for 2010, compared to $7.5 million (or $0.18 basic earnings per share and $0.17 diluted earnings per 
share) for 2009, due primarily to increased net sales and improved gross profit.

Net sales 

2009 
 434,357  

$ 

2008  
 432,785  

$ 

Net  sales  for  2009  increased $1.6 million  to  $434.4 million  from  $432.8  million  for 2008. During 2009, we  experienced a 
2.5% increase in units sold and a 2.1% decrease in average selling prices (“ASP”). Net sales remained relativity flat year over year 
even though toward the end of 2008 and the beginning of 2009, we experienced a sales decrease in all industry segments, primarily 
due to the global economic downturn, as well as a decrease in our wafer fabrication facilities and subcontracting business. Toward the 
end of 2009, we began to see net sales levels return to the levels in 2008, before the global economic downturn. 

The following table sets forth the geographic breakdown of our net sales for the periods indicated based on the country to

$ 121,207 
27.9% 

2008  
$ 300,257 
$ 132,528 
30.6% 

Cost of goods sold increased $12.9 million, or 4.3%, for 2009 to $313.2 million, compared to $300.3 million for 2008. As a 
percent  of  sales,  cost  of  goods  sold  increased  from  69.4%  for  2008  to  72.1%  for  2009.  Our  average  unit  cost  (“AUP”)  increased 
approximately 1.1%. The increase in cost of goods sold and the percentage of sales increase was due to the lower capacity utilization 
in our manufacturing operations mainly due to the global economic downturn. 

Gross  profit  for  2009  decreased  8.5%  to  $121.2 million  from  $132.5 million  for  2008.  Gross  profit  as  a  percentage  of  net 
sales was 27.9% for 2009, compared to 30.6% for 2008. The decreased gross margin was primarily due to lower capacity utilization in 
our manufacturing operations caused by the global economic downturn. 

SG&A 

2009 
$ 70,396 

2008  
$ 68,373 

SG&A  for  2009  increased  $2.0 million,  or  3.0%,  to  $70.4 million,  compared  to  $68.4  million  for  2008,  due  primarily  to 
additional SG&A expenses related to the Zetex operations, partially offset by the decrease in overall expense in connection with our 
cost reduction initiatives that were implemented during the first  quarter of 2009. SG&A, as a percentage of net sales, was 16.2% in 
2009, compared to 15.8% in 2008.

R&D 

2009 
$ 23,757 

2008  
$ 21,882 

R&D  for  2009  increased  $1.9 million  to  $23.8 million,  or  5.5%  of  net  sales,  from  $21.9  million,  or  5.1%  of  net  sales,  for 
2008. The increase was due primarily to additional R&D expenses related to the Zetex operations, partially offset by the decrease in 
overall expense in connection with our cost reduction initiatives that were implemented during the first quarter of 2009.   

Amortization of acquisition-related 
intangible assets 

2009  

$ 4,665 

2008  

$ 3,706 

Amortization of acquisition-related intangibles for 2009 increased $1.0 million to $4.7  million from  $3.7 million for 2008. 

The increase was due primarily to the acquisition of Zetex, which occurred in June 2008. 

In-process research and development 
("IPR&D") 

2009 

$ - 

2008  

$ 7,865 

During the third quarter of 2008, per SFAS No. 141, we recorded an approximately $7.9 million one-time, non-cash expense 
associated with the identification of acquired intangible IPR&D in connection with the acquisition of Zetex, which had not yet reached 
technological feasibility and had no alternative future use as of the acquisition date. 

Interest income 

2009 
$ 4,871 

2008  
$ 11,991 

Interest  income  for  2009  decreased  to  $4.9 million,  compared  to  $12.0 million  for  2008,  due  primarily  to  a  decrease  in 
interest income earned on our short-term investment securities. Interest income for 2009 was impacted by the interruption in the ARS 
auction markets.   

Interest expense 

2009 
7,471  

2008 
9,044  

$ 

$ 

Interest expense for 2009 was $7.5 million, compared to $9.0 million for 2008. The $1.6 million decrease is due primarily to 
the reduced interest paid due to the repurchase and retirement of $94.9 million par value of Notes during the fourth quarter of 2008 
and throughout 2009. The decrease in interest expense was partially offset by the interest expense charged in connection with our “no 
net cost” loan with the offsetting interest earned being recorded in interest income. 

Amortization of debt discount 

2009 
 8,302  

2008  
 10,690  

$ 

$ 

Amortization of debt discount for 2009 was $8.3 million, compared to $10.7 million for 2008. The $2.4 million decrease in 
amortization of debt discount was due primarily to the repurchase and retirement of $94.9 million par value of Notes during the fourth 
quarter of 2008 and throughout 2009. 

Other income (expense) 

2009 
$ (777) 

2008  
$ 9,501 

Other  expense  for  2009  was  $0.8 million,  compared  to  other  income  of  $9.5 million  for  2008.  The  $10.3 million  decrease 
was due primarily to a $15.7 gain from extinguishment of debt (in the fourth quarter of 2008, we repurchased $46.5 million of our 
Notes for approximately $23.2 million in cash) in 2008, offset by foreign currency transaction losses.

Income tax provision 

2009 
$ 1,302 

2008  
$ (2,158) 

We  recognized  income  tax  expense  of  $1.3 million  for  2009,  resulting  in  an  effective  tax  rate  of  11.7%,  as  compared  to 
(7.6)% for 2008. Our higher effective tax rate compared with the same period of the prior year was impacted by the non-cash income 
tax expense of approximately $7.5 million associated with repatriating earnings of foreign subsidiaries to the U.S. This was partially 
offset by provision-to-return adjustments recorded in 2009.   

Noncontrolling interest 

2009 
$ 2,335 

2008  
$ 2,290 

Noncontrolling  interest  primarily  represents  the  minority  investor’s  share  of  the  earnings  of  our  China  and  Taiwan 
subsidiaries for 2008 and 2009. The joint venture investments were eliminated in the consolidations of our financial statements, and 
the  activities  of  our  China  and  Taiwan  subsidiaries  were  included  therein.  The  noncontrolling  interest  in  the  subsidiaries  and  their 
equity  balances  are  reported  separately  in  the  consolidation  of  our  financial  statements,  and  the  activities  of  these  subsidiaries  are 
included therein. 

Net income attributable to common stockholders 

2009 
$ 7,513 

2008  
$ 28,239 

Net  income  attributable  to  common  stockholders  decreased  73.4%  to  $7.5 million  (or  $0.18  basic  earnings  per  share  and 
$0.17 diluted earnings per share) for 2009, compared to $28.2 million (or $0.69 basic earnings per share and $0.66 diluted earnings 
per share) for 2008, due primarily to the global decrease in demand for our products we experienced during most of 2009. 

Financial Condition 

Liquidity and Capital Resources 

Our  primary  sources  of  liquidity  are  cash  and  cash  equivalents,  funds  from  operations  and  borrowings  under  our  credit 
facilities.  As  of  December  31,  2010,  we have  a  U.S.  credit  agreement  for  a  $10  million revolving  credit  facility  and  a $10  million 
uncommitted  facility  with  no  outstanding  borrowings  and  have  foreign  credit  facilities  giving  us  total  borrowing  capacities  of 
approximately  $46.7  million  of  which  approximately  $3.3  million  has  been  used  for  import  and  export  guarantees.    Our  primary 
liquidity  requirements  have  been  to  meet  our  inventory  and  capital  expenditure  needs  and  to  fund  on-going  operations.    For  2010, 
2009  and  2008,  our  working  capital  was  $289.4  million,  $354.3  million,  and  $209.6  million,  respectively.    Our  working  capital 
decreased in 2010 mainly due to our Notes being reclassified from long-term debt to current liabilities, partially offset by an increase 
in  cash,  accounts  receivables  and  inventories.    We  expect  cash  generated  by  our  U.S.  and  international  operations,  together  with 
existing  cash,  cash  equivalents,  and  available  credit  facilities  to  be  sufficient  to  cover  cash  needs  for  working  capital  and  capital 
expenditures for at least the next 12 months.  

On October 12, 2006, we issued and sold convertible senior notes with an aggregate principal amount of $230 million due 2026 
(the “Notes”), which pay 2.25% interest per annum on the principal amount of the Notes, payable semi-annually in arrears on April 1 and 
October 1 of each year, beginning on April 1, 2007.  During 2010, 2009 and 2008, we repurchased $60.9 million principal amount of the 
Notes  for  approximately  $34.5  million  in  cash  and  $34.8  million  principal  amount  of  the  Notes  in  exchange  for  approximately  $31.4 
million in shares of Common Stock.  As of December 31, 2010, we have repurchased a total of $95.7 million principal amount of Notes.  
On October 1, 2011, the holders of our Notes can require us to purchase all or a portion of their Notes at a purchase price in cash equal to 
100% of the principal amount of the Notes to be purchased, plus any accrued and unpaid interest to, but excluding, the purchase date. 
Therefore,  during  the  fourth  quarter  of  2010,  we  reclassified  our  Notes  from  long-term  debt  to  current  liabilities.  Should  the  holders 
choose to require us to purchase their Notes, we will be required to use available funds and/or seek alternative means to service the debt.  
See Notes 1 and 10 of “Notes to Consolidated Financial Statements” of this Annual Report for additional information. 

In 2010, 2009 and 2008, our capital expenditures were $86.6 million, $25.9 million and $53.4 million, respectively.  Our capital 
expenditures for these periods were primarily related to  manufacturing expansion in our facilities in China and, to a lesser extent, our 
wafer fabrication facility in the U.S. and office buildings in the U.S. and China. Capital expenditures for 2010 were approximately 14.1% 
of our net sales, which is an increase from our historical 10% to 12% model of net sales model as we increased capacity due to increased 
demand.

On  October  29,  2008,  we  reached  a  settlement  with  UBS  AG  and  affiliates  (“UBS  AG”),  in regard  to  our  ARS  portfolio, 
which gave us the option to “put” the ARS portfolio back to UBS AG at any time from June 30, 2010 through July 2, 2012 at par 
value in exchange for cash.  As part of our settlement with UBS AG, on November 4, 2008, we accepted an offer of a “no net cost” 
loan with one of its affiliates, UBS BANK USA (“UBS Bank”), which was collateralized by our ARS portfolio.  Under the “no net 
cost” loan, the interest rate we paid on the “no net cost” loan did not exceed the interest rate earned on the pledged ARS portfolio.  On 
November 10, 2009, we received a credit line of up to the full par value of our ARS portfolio.  On June 30, 2010, we put back our 
ARS portfolio to UBS AG at par value pursuant to the settlement agreement.  Upon exercise of the put option, we liquidated our ARS, 
for cash and used the proceeds to fully repay the related “no net cost” loan with UBS Bank. 

During 2010, we announced an investment agreement with the Management Committee of the CDHT.  Under this agreement, 
we  have  agreed  to  form  a  joint  venture  with  a  Chinese  partner,  Chengdu  Ya  Guang  Electronic  Company  Limited,  to  establish  a 
semiconductor manufacturing facility for the purpose of providing surface mounted component production, assembly and testing, and 
integrated  circuit  assembly  and  testing  in  Chengdu,  People’s  Republic  of  China.    We  initially  will  own  at  least  95%  of  the  joint 
venture.    The manufacturing  facility  will  be  developed  in  phases over  a  ten  year  period,  and we  are expected  to  contribute  at  least 
$47.5 million to the joint venture in installments during the first three years.  The CDHT will grant the joint venture a fifty year land 
lease, provide temporary facilities for up to three years at a  subsidized rent while the joint venture builds the manufacturing facility 
and  provide  corporate  and  employee  tax  incentives,  tax  refunds,  subsidies  and  other  financial  support  to  the  joint  venture  and  its 
qualified  employees.    If  the  joint  venture  fails  to  achieve  specified  levels  of  investment,  the  investment  agreement  allows  for  a 
renegotiation  as  well  as  the  option  to  repay  a  portion  of  such  financial  support.    This  is  a  long-term,  multi-year  project  that  will 
provide additional capacity once we have reached the maximum production capacity at our Shanghai facilities in the next few years.  

Discussion of Cash Flows 

Cash  and  cash  equivalents  have  increased  from  $103.5 million  at  December 31,  2008,  to  $242.0  million  at 
December 31, 2009, then increased to $270.9 million at December 31, 2010.  The increase from 2008 to 2009 was primarily due 
to net cash provided by operating activities  and drawing up to the full value of the “no net cost” loan.  The increase during 
2010 was primarily due to net cash provided by operating activities.

Operating Activities 

Net cash provided by operating activities during 2010 was $118.0 million, resulting primarily from $80.3 million of net income 
in the period, $47.4 million of depreciation and amortization, $12.7 million increase in income tax payable, $13.1 million from non-cash 
share-based  compensation,  $15.0  million  increase  in  accounts  payable  and  accrued  liabilities  and  $7.7  million  from  amortization  of 
discount on Notes, partially offset by a $30.4 million increase in inventory and a $23.6 million increase in accounts receivables.  Net cash 
provided by operating activities was $65.5 million for 2009 and $57.2 million for 2008. 

Net cash provided by operating activities increased by $52.5 million from 2009 to 2010.  This increase resulted primarily from 

an increase in net income (from $9.9 million in 2009 to $80.3 million in 2010), partially offset by a $30.4 million increase in inventory.   

Net cash provided by operating activities increased by $8.5 million from 2008 to 2009.  This increase resulted primarily from 
a $18.7 million increase in net working capital and a $14.5 million decrease in gain from extinguishment of debt, partially offset by a 
$20.7 million decrease in net income (from $30.5 million in 2008 to $9.9 million in 2009).   

Investing Activities 

Net cash provided by investing activities for 2010 was $209.6 million, resulting primarily from $296.6 million in proceeds from 

sale of securities, offset by $88.8 million in capital expenditures.   

Net cash provided by investing activities for 2009 was $1.9 million, resulting primarily from $24.0 million in proceeds from 

sale of securities, offset by $22.5 million in capital expenditures.  

Net cash used by investing activities for 2008 was $203.5 million, resulting primarily from $153.2 million in acquisitions, net 

of cash acquired and $53.2 million in capital expenditures. 

Financing  Activities 

Net  cash  used  by  financing  activities  for  2010  was  $295.3 million,  resulting  primarily  from  $303.2  million  in  repayments  of 

lines of credit and short-term debt, which was mainly the repayment of our “no net cost” loan. 

Net cash provided by financing activities for 2009 was $67.9 million, resulting primarily from the proceeds of lines of credit 
and short-term debt of $126.6 million, mainly from the “no net cost” loan, partially offset by $45.1 million in repayments of short-
term debt and $13.4 million in repayments of long-term debt. 

Net  cash provided by  financing  activities  for 2008 was  $196.9 million,  resulting  primarily  from  the  proceeds  of  long-term 

debt of $212.7 million from the “no net cost” loan, partially offset by $24.5 million in repayments of long-term debt. 

Debt instruments 

On November 25, 2009 we entered into a credit agreement with Bank of America, N.A. (“Bank of America”) as modified by 
a  certain  letter  dated  as  of  March  31,  2010,  the  First  Amendment  to  Credit  Agreement  dated  as  of  July  16,  2010,  the  Second 
Amendment to Credit Agreement dated as of November 24, 2010 and the Third Amendment to Credit Agreement dated as of February 
4,  2011  (collectively  the  “Credit  Agreement”).    The  Credit  Agreement  provides  for  a  $10  million  revolving  credit  facility  (the 
“Revolver”) and a $10 million uncommitted facility (the “Uncommitted Facility”).  The Revolver includes a $1.5 million sublimit for 
letters of credit. Both the Revolver and the Uncommitted Facility mature on November 23, 2011 (the “Maturity Date”). The proceeds 
under the Revolver and the Uncommitted Facility may be used for general corporate purposes, to finance temporary cash shortages 
and to minimize taxes associated with moving cash between countries.  As of December 31, 2010, there were no amounts outstanding 
under the Revolver or the Uncommitted Facility.   

Under  the  Revolver,  we  may  borrow  through  Base  Rate  Committed  Loans  in  United  States  Dollars  (“USD”),  or  through 
Eurocurrency  Rate  Committed  Loans  in  USD,  Euros  or  British  Pounds  Sterling.    Base  Rate  Committed  Loans  bear  interest  on  the 
outstanding principal amount from the applicable borrowing date at a rate per annum equal to the Federal Funds Rate plus one half of 
one percent (0.50%) per annum.  Eurocurrency Rate Committed Loans bear interest on the outstanding principal amount at a rate per 
annum equal to the LIBOR 1 Month Fixed Rate plus three percent (3%) per annum.   

Under  the  Uncommitted  Facility,  we  may  borrow  only  in  USD,  and  each  borrowing  will  bear  interest  on  the  outstanding 
principal amount from the applicable borrowing date at the rate per annum quoted to us by Bank of America and accepted by us prior 
to  such  borrowing.    Each  borrowing  under  the  Uncommitted  Facility  and  accrued  and  unpaid  interest  thereon,  shall  be  due  and 

-44-

payable, on the earlier of (a) the Maturity Date, or (b) a date set by Bank of America and accepted by us prior to such borrowing under 
the Uncommitted Facility. 

We may prepay any borrowing under the Revolver or the Uncommitted Facility in full or in part at any time; however, we 
shall  repay  to  Bank  of  America  on  the  Maturity  Date  the  aggregate  principal  amount  of  any  borrowing  under  the  Revolver  or  the 
Uncommitted Facility outstanding on such date. 

As part of the Credit Agreement, we and each of our subsidiaries (including Diodes Zetex Limited) agreed to have Bank of 

America as our principal depository bank, including for the maintenance of business, operating and administrative deposit accounts.   

Any borrowing and obligations under the Revolver or under the Uncommitted Facility is secured by accounts, chattel paper, 
deposit  accounts  and  inventory,  and  all  dividends,  distributions,  and  income  attributable  to  proceeds,  products,  additions  to, 
substitutions, replacements and supporting obligations for, model conversions, and accessions of the foregoing, of us and of certain of 
our  subsidiaries.    Certain  subsidiaries  of  ours  also  guaranty  any  borrowing  and  obligations  and  pledge  their  interests  to  Bank  of 
America in certain subsidiary stock owned by such subsidiary guarantors. 

In  addition,  the  Credit  Agreement  contains  certain  restrictive  and  financial  covenants,  including,  but  not  limited  to,  us 
maintaining on a consolidated basis a Fixed Charge Coverage Ratio of not less than 2.00 to 1.0 and a Quick Ratio of not less than 1.50 
to 1.0 (excluding our Notes for both ratios). 

As  of  December  31,  2010,  our  U.S.,  Asia  and  Europe  subsidiaries  have  available  lines  of  credit  of  up  to  an  aggregate  of 
approximately  $50  million,  with  several  financial  institutions.    These  lines  of  credit,  except  for  one  Taiwanese  credit  facility,  are 
collateralized by each subsidiary’s premises, are unsecured, uncommitted and, in some instances, may be repayable on demand. Loans 
under these lines of credit bear interest at LIBOR or similar indices plus a specified margin.  At December 31, 2010, there were no 
amounts outstanding on these lines of credit, and the interest rates ranged from 1.4% to 1.9%.  See Note 10 of “Notes to Consolidated 
Financial Statements” of this Annual Report for additional information. 

On October 12, 2006, we issued and sold convertible senior notes with an aggregate principal amount of $230 million due 2026 
(the “Notes”), which pay 2.25% interest per annum on the principal amount of the Notes, payable semi-annually in arrears on April 1 and 
October 1 of each year, beginning on April 1, 2007.  During 2010, 2009 and 2008, we repurchased $60.9 million principal amount of the 
Notes  for  approximately  $34.5  million  in  cash  and  $34.8  million  principal  amount  of  the  Notes  in  exchange  for  approximately  $31.4 
million in shares of Common Stock.  As of December 31, 2010, we have repurchased a total of $95.7 million principal amount of Notes.  
On October 1, 2011, the holders of our Notes can require us to purchase all or a portion of their Notes at a purchase price in cash equal to 
100% of the principal amount of the Notes to be purchased, plus any accrued and unpaid interest to, but excluding, the purchase date. 
Therefore,  during  the  fourth  quarter  of  2010,  we  reclassified  our  Notes  from  long-term  debt  to  current  liabilities.  Should  the  holders 
choose to require us to purchase their Notes, we will be required to use available funds and/or seek alternative means to service the debt.  
See Notes 1 and 10 of “Notes to Consolidated Financial Statements” of this Annual Report for additional information. 

We may from time to time seek to repurchase our outstanding debt in the open market, in privately negotiated transactions or 
otherwise.  Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions 
and other factors.  The amounts involved may be material. 

Off-Balance Sheet Arrangements 

We  do  not  have  any  transactions,  arrangements  and  other  relationships  with  unconsolidated  entities  that  will  affect  our 
liquidity or capital resources.  We have no special purpose entities that provided off-balance sheet financing, liquidity or market or 
credit risk support, nor do we engage in leasing, hedging or research and development services, that could expose us to liability that is 
not reflected on the face of our financial statements.

On October 1, 2011, holders of our Notes may require us to purchase all or a portion of their Notes at a purchase price in cash 
equal to 100% of the principal amount of the Notes to be purchased, plus any accrued and unpaid interest to, but excluding, the purchase 
date.  Therefore, as of December 31, 2010, the Notes are classified as short-term debt and not included in the above table. 

Tax liabilities are not included in the above contractual obligations as we can not make reasonable estimates of the amount 
and  period  in  which  those  tax  liabilities  would  be  paid.    See  “Accounting  for  income  taxes”  below  and  Note  15  of  “Notes  to 
Consolidated Financial Statements” of this Annual Report for additional information. 

Critical Accounting Policies and Estimates 

The  preparation  of  financial  statements  in  conformity  with  generally  accepted  accounting  principles  in  the  United  States  of 
America (“GAAP”) requires that management make estimates and assumptions that affect the reported amounts of assets and liabilities 
and  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of  revenues  and 
expenses  during  the  reporting  period.    On  an  on-going  basis,  we  evaluate  our  estimates,  which  are  based  upon  historical  experiences, 
market  trends  and  financial  forecasts  and  projections,  and  upon various  other  assumptions  that  management  believes  to  be  reasonable 
under the circumstances at that certain point in time.  Actual results may differ, significantly at times, from these estimates under different 
assumptions or conditions. 

We believe the following critical accounting policies and estimates affect the significant estimates and judgments we use in the 

preparation of our consolidated financial statements, and may involve a higher degree of judgment and complexity than others. 

Revenue recognition 

Revenue is recognized when there is persuasive evidence that an arrangement exists, when delivery has occurred, when the 
price  to  the buyer  is  fixed or  determinable and  when  collectability  of  the  receivable  is  reasonably  assured.  These  elements  are  met 
when  title  to  the  products  is  passed  to  the  buyers,  which  is  generally  when  product  is  shipped  to  the  customers.    Generally,  we 
recognize revenue upon shipment to manufacturers (direct ship) as well as upon sales to distributors using the "sell in" model, which is 
when product is shipped to the distributors (point of purchase).   

Certain customers have limited rights of return and/or are entitled to price adjustments on products held in their inventory or 
upon  sale  to  their  end  customers.    We  reduce  net  sales  in  the  period  of  sale  for  estimates  of  product  returns,  distributor  price 
adjustments  and  other  allowances.    Our  reserve  estimates  are  based  upon  historical  data  as  well  as  projections  of  sales,  distributor 
inventories, price  adjustments,  average  selling prices  and market  conditions.   Actual  returns  and  adjustments  could  be  significantly 
different from our estimates and provisions, resulting in an adjustment to net sales.   

We record allowances/reserves for the following items: (i) ship and debit, which arise when we, from time to time based on 
market  conditions,  issue  credit  to  certain  distributors  upon  their  shipments  to  their  end  customers,  (ii)  stock  rotation,  which  are 
contractual obligations that permit certain distributors, twice a year, to return a portion of their inventory based on historical shipments

to them in exchange for an equal and offsetting order, and (iii) price protection, which arise when market conditions cause average 
selling prices to decrease and we issue credit to certain distributors on their inventory. 

Ship and debit reserves are recorded as a reduction to net sales with a corresponding reduction to accounts receivable.  Stock 
rotation reserves are recorded as a reduction to net sales with a corresponding reduction to cost of goods sold for the estimated cost of 
inventory  that  is  expected  to  be  returned.    Price  protection  reserves  are  recorded  as  a  reduction  to  net  sales  with  a  corresponding 
increase in accrued liabilities. 

Inventories 

Inventories are stated at the lower of cost or market value.  Cost is determined principally by the first-in, first-out method.  On an 
on-going basis, we evaluate our inventory for obsolescence and slow-moving items.  This evaluation includes analysis of sales levels, 
sales projections, and purchases by item, as well as raw material usage related to our manufacturing facilities. If our review indicates a 
reduction in utility below carrying value, we reduce our inventory to a new cost basis. If future demand or market conditions are different 
than  our  current  estimates,  an  inventory  adjustment  may  be  required,  and  would  be  reflected  in  cost  of  goods  sold  in  the  period  the 
revision is made. 

Accounting for income taxes 

As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of 
the tax jurisdictions in which we operate.  This process involves using an asset and liability approach whereby deferred tax assets and 
liabilities are recorded for differences in the financial reporting bases and tax bases of our assets and liabilities.  Deferred tax accounting 
requires that we evaluate net deferred tax assets by jurisdiction to determine if these assets will more likely than not be realized in the 
foreseeable future.  This test requires the consideration of the reversal of temporary differences between book and tax basis, the projection 
of our taxable income into future years and the use of tax planning strategies to determine if it is more likely than not that we will realize 
the tax assets.  This analysis requires considerable judgment and is subject to change to reflect future events and changes in the tax laws. 

We are involved in various tax matters, some of whose outcome is uncertain. For purposes of evaluating whether or not a tax 
position  is  uncertain  (i) we  presume  the  tax  position  will  be  examined  by  the  relevant  taxing  authority  that  has  full  knowledge  of  all 
relevant information, (ii) technical merits of a tax position are derived from authorities such as legislation and statutes, legislative intent, 
regulations, rulings and case law and their applicability to the facts and circumstances of the tax position, and (iii) each tax position is 
evaluated without consideration of the possibility of offset or aggregation with other tax positions taken. A tax benefit from an uncertain 
position may be recognized only if it is “more likely than not” that the position is sustainable, based on its technical merits, and the tax 
benefit  of  a  qualifying  position  is  the  largest  amount  of  tax  benefits  that  is  greater  than  50%  likely  of  being  realized  upon  ultimate 
settlement with a taxing authority having full knowledge of all relevant information.   

Goodwill and long-lived assets 

Goodwill  is  the  cost  of  an  acquisition  less  the  fair  value  of  the  net  assets  of  the  acquired  business.    We  test  goodwill  for 
impairment on an annual basis, on October 1, and between annual tests if indicators of potential impairment exist.  The fair value of 
the reporting units was calculated using the income approach and the market approach.  Under the income approach, the fair value of 
the reporting units was calculated by estimating the present value of associated future cash flows.  Under the market approach, the fair 
value was calculated using the guideline public company method and the mergers and acquisitions method.  We determined that the 
fair value of the reporting units exceeds the carrying value of units, thus indicating that the goodwill was not impaired as of October 1, 
2010. 

We  assess  the  impairment  of  certain  long-lived  assets  at  least  annually  and  whenever  events  or  changes  in  circumstances 
indicate  that  the  carrying  value  may  not  be  recoverable.    We  assess  the  recoverability  of  our  long-lived  and  intangible  assets  by 
determining whether the unamortized balances can be recovered through undiscounted future net cash flows of the related assets.  If such 
asset is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset 
exceeds its fair market value using a discounted cash flow analysis. 

Share-based compensation 

We use the Black-Scholes-Merton model to determine the fair value of stock options on the date of grant.   The amount of 
compensation  expense  recognized  using  the  Black-Scholes-Merton  model  requires  us  to  exercise  judgment  and  make  assumptions 
relating to the factors that determine the fair value of our stock option grants. The fair value calculated by this model is a function of 
several factors, including the grant price, the expected future volatility, the expected term of the option and the risk-free interest rate of 
the  option.  The  expected  term  and  expected  future  volatility  of  the  options  require  our  judgment.  In  addition,  we  are  required  to 

-47-
- 47 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
 
 
estimate the expected forfeiture rate and only recognize expense for those stock options expected to vest.  We estimate the forfeiture 
rate based on historical experience and to the extent our actual forfeiture rate is different from our estimate, share-based compensation 
expense is adjusted accordingly.  Restricted stock grants are measured based on the fair market value of the underlying stock on the 
date of grant. 

Fair value measurements 

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an 
orderly transaction between market participants at the measurement date.  As such, fair value is a market-based measurement that should 
be  determined  based  on  the  assumptions  that  market  participants  would  use  in  pricing  an  assets  or  liability.  Fair  value  is  based  on  a 
hierarchy  of  valuation  techniques,  which  is  determined  on  whether  the  inputs  to  those  valuation  techniques  are  observable  or 
unobservable.  Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market 
assumptions.  These two types of inputs create a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as 
follows:  

Level 1:  Quoted prices for identical instruments in active markets. 
Level 2:  Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets 
that  are  not  active;  and  model-derived  valuations  in  which  all  significant  inputs  and  significant  value  drivers  are 
observable in active markets. 

Level 3:  Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are 

unobservable.  

Our defined benefit plan assets are valued under methods of fair value.  All of the securities held by the plan are publicly 
traded and highly liquid.  Therefore, the majority of the securities are valued under Level 1 and one security is valued under Level 2 
using quoted prices for identical or similar securities. 

Defined benefit plan 

We maintain a pension plan covering certain of our employees in the U.K. and Germany.  For financial reporting purposes, the net 
pension  and  supplemental  retirement  benefit  obligations  and  the  related  periodic  pension  costs  are  calculated  based  upon,  among  other 
things, assumptions of the discount rate for plan obligations, estimated return on pension plan assets and mortality rates.  These obligations 
and related periodic costs are measured using actuarial techniques and assumptions.  The projected unit credit method is the actuarial cost 
method used  to compute  the pension  liabilities and related expenses.  See  “Fair value measurements”  above in regard to pension plan 
assets. 

Contingencies  

From  time  to  time,  we  are  involved  in  a  variety  of  legal  matters  that  arise  in  the  normal  course  of  business.    Based  on 
information  available,  we  evaluate  the  likelihood  of  potential  outcomes.  We  record  the  appropriate  liability  when  the  amount  is 
deemed probable and reasonably estimable. In addition, we do not accrue for estimated legal fees and other directly related costs as 
they are expensed as incurred. 

Convertible Senior Notes 

Our  Notes  may  be  settled  for  cash  upon  conversion.    As  such,  we  allocated  a  portion  of  the  proceeds  received  from  the 
issuance  of  the  Notes  between  a  liability  and  equity  component  by  determining  the  fair  value  of  the  liability  component  using  our 
nonconvertible  borrowing  rate.    The  effective  rate  of  the  liability  component  was  determined  by  obtaining  a  comparable  yield  for 
nonconvertible  notes  with  terms  and  conditions  comparable  to  our  Notes  as  of  the  date  of  issuance.    The  difference  between  the 
proceeds of the Notes and the fair value of the liability component was recorded as a discount on the debt with a corresponding offset 
to additional paid-in capital.  The resulting debt discount is amortized as additional non-cash interest expense, which we refer to as 
amortization of debt discount, over the expected life of the Notes using the effective interest method.

Quantitative and Qualitative Disclosures About Market Risk 

Foreign Currency Risk 

We  face  exposure  to  adverse  movements  in  foreign  currency  exchange  rates,  primarily  in  Asia  and  Europe.  Our  foreign 
currency risk may change over time as the level of activity in foreign markets grows and could have a material adverse impact upon 
our financial results. Certain of our assets, including certain bank accounts and accounts receivable, and liabilities exist in non−U.S. 
dollar  denominated  currencies,  which  are  sensitive  to  foreign  currency  exchange  fluctuations.  These  currencies  are  principally  the 
Chinese Yuan, the Taiwanese dollar and the British Pound Sterling and, to a lesser extent, the Japanese Yen, the Euro and the Hong 
Kong  dollar.  In  the  future,  we  may  enter  into  hedging  arrangements  designed  to  mitigate  foreign  currency  fluctuations.    See  “Risk 
Factors – We are subject to foreign currency risk as a result of our international operations.” in Part I, Item 1A of this Annual Report 
for additional information. 

Effect on Reporting Income 

Certain of our subsidiaries’ have a functional currency that differs from the currencies in which some of their expenses are 
denominated. Our income and expenses are based on a mix of currencies and a decline in one currency relative to the other currencies 
could  adversely  affect  our  results  of  operations.  Furthermore,  our  results  of  operations  are  reported  in  U.S.  dollars,  which  is  our 
reporting currency. In the event the U.S. dollar weakens against a foreign currency, we will experience a currency transaction loss, 
which could adversely affect our results of operations. If a foreign currency were to weaken or (strengthen) by 1.0% against the U.S. 
dollar, we would experience currency transaction gain or (loss) of approximately $0.2 million per quarter. 

Foreign Currency Transaction Risk 

We also are subject to foreign currency risk arising from intercompany transactions that are expected to be settled in cash in 
the near term where the cash balances are held in denominations other than our subsidiaries’ functional currency. If exchange rates 
weaken against the functional currency, we would incur a remeasurement gain in the value of the cash balances, and if the exchange 
rates strengthen against the functional currency, we would incur a remeasurement loss in the value of the cash balances, assuming the 
net monetary asset balances remained constant. Our ultimate realized gain or loss with respect to currency fluctuations will generally 
depend on the size and type of transaction, the size and currencies of the net monetary assets and the changes in the exchange rates 
associated with these currencies. If the Chinese Yuan, the Taiwanese dollar, the Euro and the British Pound Sterling were to weaken 
or  (strengthen)  by  1.0%  against  the  U.S.  dollar,  we  would  experience  currency  transaction  gain  or  (loss)  of  approximately  $0.3 
million. Net foreign exchange transaction gains or (losses) are included in other income and expense. 

Foreign Currency Translation Risk 

When our foreign subsidiaries’ books are maintained in their functional currency, fluctuations in foreign currencies impact 
the  amount  of total  assets  and  liabilities  that  we  report  for our  foreign subsidiaries upon  the  translation of  these  amounts  into  U.S. 
dollars  for  reporting  purposes.  All  elements  of  the  subsidiaries  financial  statements,  except  for  stockholders’  equity  accounts,  are 
translated using a currency exchange rate. Assets and liabilities denominated in foreign currencies are translated at the exchange rate 
on  the  balance  sheet  date.  Income  and  expense  accounts  denominated  in  foreign  currencies  are  translated  at  the  weighted−average 
exchange  rate  during  the  period  presented.  Resulting  translation  adjustments  are  recorded  as  a  separate  component  of  accumulated 
other  comprehensive  income  or  loss  within  stockholders’  equity  in  the  consolidated  balance  sheets,  which  are  accumulated  in  this 
account until sale or liquidation of the foreign entity investment, at which time they are reported as adjustments to the gain or loss on 
sale of investment. 

Foreign Currency Denominated Defined Benefit Plans 

We  have  a  contributory  defined  benefit  plan  that  covers  certain  employees  in  the  U.K.  and  Germany.  The  defined  benefit 
plan is closed to new entrants and frozen with respect to future benefit accruals. The retirement benefit is based on the final average 
compensation and service of each eligible employee. December 31 is our annual measurement date and on measurement date, defined 
benefit plan assets are determined based on fair value. Defined benefit plan assets consist primarily of high quality corporate bonds 
that are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating to the terms of 
the related pension liability. The net pension and supplemental retirement benefit obligations and the related periodic costs are based 
on, among other things, assumptions of the discount rate, estimated return on plan assets and mortality rates. These obligations and 
related periodic costs are measured using actuarial techniques and assumptions. The projected unit credit method is the actuarial cost 
method used to compute the pension liabilities and related expenses. 

-49-

As  of  December  31,  2010,  the  plan  was  underfunded  and  a  liability  of  $24.9  million  was  reflected  in  our  consolidated 
financial statements as a noncurrent liability. The amount recognized in accumulated other comprehensive income was a net loss of 
$15.9  million.  If  the  British  Pound  Sterling  were  to  (weaken)  or  strengthen  by  1.0%  against  the  U.S.  dollar,  we  would  experience 
currency  translation  liability  (decrease)  or  increase  of  approximately  $0.3  million.  The  weighted−average  discount  rate  assumption 
used  to  determine  benefit  obligations  as  of  December  31,  2010  was  5.4%.  A  0.2%  increase/(decrease)  in  the  discount  rate  used  to 
calculate the net period benefit cost for the year would reduce annual benefit cost by $0.1 million. A 0.1% increase/(decrease) in the 
discount  rate  used  to  calculate  the  year−end  projected  benefit  obligation  would  increase/(decrease)  the  year−end  projected  benefit 
obligation by approximately $2.1 million. The expected return on plan assets is determined based on historical and expected future 
returns  of  the  various  assets  classes  and  as  such,  each  1.0%  increase/(decrease)  in  the  expected  rate  of  return  assumption  would 
increase/(decrease)  the  net  period  benefit  cost  by  approximately  $0.8  million.  The  asset  value  of  the  defined  benefit  plan  has  been 
volatile in recent years due primarily to wide fluctuations in the U.K. equity markets and bond markets.  See “Risk Factors - Due to 
the recent fluctuations in the United Kingdom’s equity markets and bond markets, changes in actuarial assumptions for our defined 
benefit plan could increase the volatility of the plan’s asset value, require us to increase cash contributions to the plan and have a 
negative  impact  on  our  results  of  operations  and  financial  condition.”  in  Part  I,  Item  1A  of  this  Annual  Report  for  additional 
information. 

Interest Rate Risk   

We  have  credit  facilities  with  financial  institutions  in  the  U.S.,  Asia  and  Europe  as  well  as  other  debt  instruments  with 
interest rates equal to LIBOR or similar indices plus a negotiated margin.  A rise in interest rates could have an adverse impact upon 
our cost of working capital and our interest expense.  As a matter of policy, we do not enter into derivative transactions for speculative 
purposes.  As of December 31, 2010, our outstanding principal debt under our interest-bearing credit agreements was $138.4 million, 
including $134.3 million principal amount of convertible notes with a fixed interest rate of 2.25%.  Based on an increase or decrease 
in interest rates by 1.0% for the year on our credit facilities, which currently have no outstanding borrowings, our annual interest rate 
expense would increase or decrease by approximately $0.5 million. 

Political Risk   

We  have  a  significant  portion  of  our  assets  in  mainland  China,  Taiwan  and  the  U.K.    The  possibility  of  political  conflict 
between the any of these countries or with the U.S. could have a material adverse impact upon our ability to transact business through 
these important business channels and to generate profits.  See “Risk Factors” – Risks Related to our International Operations” in Part 
I, Item 1A of this Annual Report for additional information. 

Inflation Risk   

Inflation did not have a material effect on net sales or net income in fiscal year 2010.  A significant increase in inflation could 

affect future performance.   

Credit Risk   

The  success  of  our  business  depends,  among  other  factors,  on  the  strength  of  the  global  economy  and  the  stability  of  the 
financial markets, which in turn affect our customers’ demand for our products, the ability of our customers to meet their payment 
obligations, the likelihood of customers canceling or deferring existing orders and end-user consumers’ demand for items containing 
our products in the end-markets we serve.  We provide credit to customers in the ordinary course of business and perform ongoing 
credit evaluations, while at times providing extended terms. We believe that our exposure to concentrations of credit risk with respect 
to trade receivables is largely mitigated by dispersion of our customers over various geographic areas, operating primarily in electronics 
manufacturing and distribution.  We believe our allowance for doubtful accounts is sufficient to cover customer credit risks.

Controls and Procedures 

Disclosure Controls and Procedures 

Our Chief Executive Officer, Keh-Shew Lu, and Chief Financial Officer, Richard D. White, with the participation of 
the Company's management, carried out an evaluation of the effectiveness of our disclosure controls and procedures pursuant to 
Exchange Act Rule 13a-15(e). Based upon that evaluation, the Chief Executive Officer and the Chief Financial Officer believe 
that, as of the end of the period covered by this report, our disclosure controls and procedures are effective at the reasonable 
assurance level to ensure that information required to be included in this report is: 

• 

• 

recorded, processed, summarized and reported within the time period specified in the Commission’s rules and 
forms; and 
accumulated  and  communicated  to  our  management,  including  the  Chief  Executive  Officer  and  the  Chief 
Financial Officer, to allow timely decisions required disclosure.  

Disclosure  controls  and  procedures,  no  matter  how  well  designed  and  implemented,  can  provide  only  reasonable 
assurance of achieving an entity's disclosure objectives. The likelihood of achieving such objectives is affected by limitations 
inherent in disclosure controls and procedures. These include the fact that human judgment in decision-making can be faulty 
and  that  breakdowns  in  internal  control  can  occur  because  of  human  failures  such  as  simple  errors,  mistakes  or  intentional 
circumvention of the established processes. 

Management’s Annual Report on Internal Control Over Financial Reporting 

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal 
control over financial reporting is a process designed by, or under the supervision of, the Company's Chief Executive Officer 
and the Chief Financial Officer and implemented by the Company's Board of Directors, management and other personnel, to 
provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for 
external purposes in accordance with generally accepted accounting principles in the United States of America. 

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

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

Under the supervision and with the participation of management, including our Chief Executive Officer and the Chief 
Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the 
framework  and  criteria  established  in  Internal  Control  -  Integrated  Framework    issued  by  the  Committee  of  Sponsoring 
Organizations  of  the  Treadway  Commission  (“COSO”).  This  evaluation  included  review  of  the  documentation  of  controls, 
testing  of  operating  effectiveness  of  controls  and  a  conclusion  on  this  evaluation.  Based  on  this  evaluation,  management 
concluded that the Company’s internal control over financial reporting was effective as of December 31, 2010.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

The Board of Directors and Stockholders 
Diodes Incorporated and Subsidiaries 

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Diodes  Incorporated  and  Subsidiaries  (the  “Company”)  as  of 
December 31, 2010 and 2009, and the related consolidated statements of income, equity and cash flows for each of the three years in 
the period ended December 31, 2010.  We also have audited the Company’s internal control over financial reporting as of December 
31,  2010,  based  on  criteria  established  in  Internal  Control  –  Integrated  Framework  issued  by  the  Committee  of  Sponsoring 
Organizations of the Treadway Commission.  The Company's management is responsible for these consolidated financial statements, 
for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over 
financial  reporting,  included  in  the  accompanying  Management’s  Annual  Report  on  Internal  Control  Over  Financial  Reporting 
appearing under Item 9A. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the 
Company's internal control over financial reporting based on our audits.  

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those 
standards  require  that  we  plan  and  perform  the  audits  to  obtain  reasonable  assurance  about  whether  the  consolidated  financial 
statements  are  free  of  material  misstatement  and  whether  effective  internal  control  over  financial  reporting  was  maintained  in  all 
material  respects.  Our  audits  of  the  consolidated  financial  statements  included  examining,  on  a  test  basis,  evidence  supporting  the 
amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates 
made  by  management,  and  evaluating  the  overall  consolidated  financial  statement  presentation.  Our  audit  of  internal  control  over 
financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.  Our 
audits  also  include  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 purposes in accordance with generally accepted accounting 
principles.  A  company's  internal  control  over  financial  reporting  includes  those  policies  and  procedures  that  (1)  pertain  to  the 
maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the 
company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in 
accordance  with  authorizations  of  management  and  directors  of  the  company;  and  (3)  provide  reasonable  assurance  regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect 
on the consolidated financial statements. 

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial 
position of Diodes Incorporated and Subsidiaries as of December 31, 2010 and 2009, and the consolidated results of their operations 
and  their  cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2010,  in  conformity  with  accounting  principles 
generally  accepted  in  the  United  States  of  America.  Also  in  our  opinion,  Diodes  Incorporated  and  Subsidiaries,  maintained,  in  all 
material respects, effective internal control over financial reporting as of December 31, 2010, based on criteria established in Internal 
Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

DIODES INCORPORATED AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
 (Amounts in thousands except per share data) 

NOTE  1 – SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES 

Nature  of  operations  –  Diodes  Incorporated  and  its  subsidiaries  (collectively,  the  “Company”)  is  a  leading  global 
manufacturer  and  supplier  of  high-quality,  application  specific  standard  products  within  the  broad  discrete,  logic  and  analog 
semiconductor  markets,  serving  the  consumer  electronics,  computing,  communications,  industrial  and  automotive  markets.  These 
products include diodes, rectifiers, transistors, MOSFETs, protection devices, functional specific arrays, single gate logic, amplifiers 
and  comparators,  Hall-effect  and  temperature  sensors,  power  management  devices  including  LED  drivers,  DC-DC  switching  and 
linear  voltage  regulators  and  voltage  references  along  with  special  function  devices  including  USB  power  switches,  load  switches, 
voltage supervisors and motor controllers. The products are sold primarily throughout Asia, North America and Europe. 

Principles of consolidation – The consolidated financial statements include the accounts of Diodes Incorporated, its wholly-
owned subsidiaries and its controlled majority-owned subsidiaries. The Company accounts for equity investments in companies over 
which  it  has  the  ability  to  exercise  significant  influence,  but  does  not  hold  a  controlling  interest,  under  the  equity  method,  and  it 
records its proportionate share of income or losses in interest and other, net in the consolidated statements of income.  All significant 
intercompany balances and transactions have been eliminated. 

Revenue recognition – Revenue is recognized when there is persuasive evidence that an arrangement exists, when delivery 
has  occurred,  when  the  price  to  the  buyer  is  fixed  or  determinable  and  when  collectability  of  the  receivable  is  reasonably  assured. 
These elements are met when title to the products is passed to the buyers, which is generally when product is shipped to the customers.  
Generally, the Company recognizes revenue upon shipment to manufacturers (direct ship) as well as upon sales to distributors using 
the "sell in" model, which is when product is shipped to the distributors (point of purchase).   

Certain customers have limited rights of return and/or are entitled to price adjustments on products held in their inventory or 
upon sale to their end customers.  The Company reduces net sales in the period of sale for estimates of product returns, distributor 
price  adjustments  and other allowances.    The  Company’s  reserve  estimates  are  based upon  historical  data  as well  as  projections of 
sales, distributor inventories, price adjustments, average selling prices and market conditions.  Actual returns and adjustments could be 
significantly different from the Company’s estimates and provisions, resulting in an adjustment to net sales.   

The Company records allowances/reserves for the following items: (i) ship and debit, which arise when the Company, from 
time to time based on market conditions, issues credit to certain distributors upon their shipments to their end customers, (ii) stock 
rotation, which are contractual obligations that permit certain distributors, twice a year, to return a portion of their inventory based on 
historical  shipments  to  them  in  exchange  for  an  equal  and  offsetting  order,  and  (iii)  price  protection,  which  arise  when  market 
conditions cause average selling prices to decrease and the Company issues credit to certain distributors on their inventory. 

Ship and debit reserves are recorded as a reduction to net sales with a corresponding reduction to accounts receivable.  Stock 
rotation reserves are recorded as a reduction to net sales with a corresponding reduction to cost of goods sold for the estimated cost of 
inventory  that  is  expected  to  be  returned.    Price  protection  reserves  are  recorded  as  a  reduction  to  net  sales  with  a  corresponding 
increase in accrued liabilities.  Revenue is reduced in the period of sale for estimates of product returns and other allowances including 
distributor  adjustments,  which  were  approximately  $31.5  million,  $17.5  million  and  $12.5  million  in  2010,  2009  and  2008, 
respectively.  

Product warranty – The Company generally warrants its products for a period of one year from the date of sale.  Historically, 

warranty expense has not been significant. 

               Cash and cash equivalents – The Company considers all highly liquid investments with maturity of three months or less at the 
date of purchase to be cash equivalents. The Company currently maintains substantially all of its day-to-day operating cash balances with 
major financial institutions. 

               Short-term  investments  –  The  Company’s  short-term  investments  in  2009  consisted  primarily  of  auction  rate  securities 
(“ARS”), which were classified as trading securities.  The Company classified the “put” option as a short-term investment as it was a 
free standing  instrument  tied  to  the ARS portfolio.   As  trading  securities, both  the  ARS  and  the  “put”  option were recorded  at  fair 
value and gains and losses were recognized in the consolidated statements of income.  On June 30, 2010, the Company put back its 
ARS  portfolio  to  UBS  AG  at  par  value  for  cash  pursuant  to  the  settlement  agreement  with  UBS  AG.    See  Note  5  for  additional 
information.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
 (Amounts in thousands except per share data) 

Allowance  for  doubtful  accounts  –  The  Company  evaluates  the  collectability  of  its  accounts  receivable  based  upon  a 
combination  of  factors,  including  the  current  business  environment  and  historical  experience.    If  the  Company  is  aware  of  a 
customer’s  inability  to  meet  its  financial  obligations,  it  records  an  allowance  to  reduce  the  receivable  to  the  amount  it  reasonably 
believes will be collected from the customer.  For all other customers, the Company records an allowance based upon the amount of 
time the receivables are past due.  If actual accounts receivable collections differ from these estimates, an adjustment to the allowance 
may  be  necessary  with  a  resulting  effect  on  operating  expense.    Accounts  receivable  are  presented  net  of  a  valuation  allowances, 
which were approximately $0.8 million, $0.7 million and $1.3 million in 2010, 2009 and 2008, respectively.  

Inventories – Inventories are stated at the lower of cost or market value.  Cost is determined principally by the first-in, first-
out method.  Cost includes materials, labor, and manufacturing overhead related to the purchase and production of inventories. Any 
write-down of inventory to the lower of cost or market at the close of a fiscal period creates a new cost basis that subsequently would 
not be marked up based on changes in underlying facts and circumstances. On an on-going basis, the Company evaluates inventory for 
obsolescence and slow-moving items.  This evaluation includes analysis of sales levels, sales projections, and purchases by item, as 
well as raw material usage related to the Company’s manufacturing facilities. If the Company’s review indicates a reduction in utility 
below carrying value, it reduces inventory to a new cost basis. If future demand or market conditions are different than the Company’s 
current estimates, an inventory adjustment may be required, and would be reflected in cost of goods sold in the period the revision is 
made.   

Property, plant and equipment – Purchased property, plant and equipment is recorded at historical cost and acquired property, 
plant and equipment is recorded at fair value on the date of acquisition.  Property, plant and equipment is depreciated using straight-line 
methods over the estimated useful lives, which range from 20 to 55 years for buildings and 3 to 10 years for machinery and equipment. The 
estimated lives of leasehold improvements range from 3 to 5 years, and are amortized over the shorter of the remaining lease term or their 
estimated useful lives.  

Goodwill and other intangible assets –Goodwill is tested for impairment on an annual basis, on October 1, and between annual 
tests if indicators of potential impairment exist.  The fair value of the reporting units was calculated using the income approach and the 
market approach.  Under the income approach, the fair value of the reporting units was calculated by estimating the present value of 
associated future cash flows. Under the market approach, the fair value was calculated using the guideline public company method 
and the mergers and acquisitions method. No impairment of goodwill has been identified during any of the periods presented.  

Convertible Senior Notes –The Company’s 2.25% convertible senior notes due 2026 (“Notes”) may be settled for cash upon 
conversion.  As such, the Company is required to allocate a portion of the proceeds received from the issuance of the Notes between a 
liability  and  equity  component  by  determining  the  fair  value  of  the  liability  component  using  the  Company’s  non-convertible 
borrowing  rate.    The  effective  rate  of  the  liability  component  was  determined  to  be  8.5%,  which  is  a  comparable  yield  for 
nonconvertible notes with terms and conditions comparable to the Company’s Notes as of the date of issuance.  The expected life of 
the Notes was determined to be five years as that is the earliest date in which the Notes can be put back to the Company at par value.   
As of December 31, 2010, nine months remain over which the discount of the liability will be amortized. 

Debt issuance costs – In connection with the issuance of the Company’s Notes, the Company incurred approximately $6.2 
million of debt issuance costs, which primarily consisted of investment banker, legal and accounting fees. Of this amount, $4.6 million 
was capitalized as other assets and is being amortized as a component of interest expense using the straight-line method over the life 
of  the  Notes  from  issuance  through  October  12,  2011.    Upon  prepayment  of  debt,  the  related  unamortized  debt  issuance  costs  are 
charged  to  expense.    Unamortized  debt  issuance  costs  were  $0.4  million  at  December  31,  2010.    The  remaining  $1.6  million  was 
recorded as part of additional paid-in capital and is not being amortized. 

Impairment  of  long-lived  assets  –  Certain  of  the  Company’s  long-lived  assets  are  reviewed  at  least  annually  and  whenever 
events  or  changes  in  circumstances  indicate  that  the  carrying  value  may  not  be  recoverable.    The  Company  considers  assets  to  be 
impaired if the carrying value exceeds the undiscounted projected cash flows from operations.  If impairment exists, the assets are written 
down to fair value or to the projected discounted cash flows from related operations.  As of December 31, 2010, the Company expects the 
remaining carrying value of assets to be recoverable.  No impairment of long-lived assets has been identified during any of the periods 
presented. The weighted average amortization period for amortizable intangible assets is approximately 7.1 years. 

Income taxes – Income taxes are accounted for using an asset and liability approach whereby deferred tax assets and liabilities are 
recorded for differences in the financial reporting bases and tax bases of the Company’s assets and liabilities. If it is more likely than not 
that some portion of deferred tax assets will not be realized, a valuation allowance is recorded.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
 (Amounts in thousands except per share data) 

Generally accepted accounting principles in the United States of America (“GAAP”) prescribes a comprehensive model for 
how companies should recognize, measure, present, and disclose in their financial statements uncertain tax positions taken or expected 
to be taken on a tax return. Tax positions shall initially be recognized in the financial statements when it is more likely than not the 
position will be sustained upon examination by the tax authorities. Such tax positions shall initially and subsequently be measured as 
the  largest  amount  of  tax  benefit  that  is  greater  than  50%  likely  of  being  realized  upon  ultimate  settlement  with  the  tax  authority 
assuming full knowledge of the position and all relevant facts.  

Research and development costs – Research and development costs are expensed as incurred. 

Shipping and handling costs – Shipping and handling costs for products shipped to customers, which are included in selling, 
general and administrative expenses, were $4.6 million, $2.9 million and $2.4 million for the years ended December 31, 2010, 2009 and 
2008, respectively. 

Concentration of credit risk –  Financial instruments, which potentially subject  the  Company to concentrations of credit risk, 
include  trade  accounts  receivable.    Credit  risk  is  limited  by  the  dispersion  of  the  Company’s  customers  over  various  geographic  areas, 
operating primarily in electronics manufacturing and distribution.  The Company performs on-going credit evaluations of its customers, and 
generally requires no collateral.  Historically, credit losses have not been significant. 

The Company currently maintains substantially all of its day-to-day cash balances with major financial institutions.  Cash balances 

are usually in excess of Federal and/or foreign deposit insurance limits. 

Valuation of financial instruments –  The  carrying value of  the  Company’s financial instruments,  including cash  and  cash 
equivalents, accounts receivable, accounts payable, working capital line of credit, and long-term  debt approximate fair value due to 
their  current market  conditions,  maturity  dates  and other  factors.  Short-term  investments,  including  trading  securities  and  the  “put” 
option related to the Company’s ARS portfolio, were recorded at their estimated fair values with changes in fair value reflected in the 
consolidated statements of income, until June 30, 2010 when the Company put back its ARS portfolio to UBS AG at par value for 
cash pursuant to the settlement agreement with UBS AG.  See Note 5 for additional information. 

Use  of  estimates  –  The  preparation  of  financial  statements  in  conformity  with  GAAP  requires  that  management  make 
estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The level 
of uncertainty in estimates and assumptions increases with the length of time until the underlying transactions are completed. Actual 
results may differ from these estimates in amounts that may be material to the consolidated financial statements and accompanying 
notes.  

Earnings per share – Earnings per share are based upon the weighted average number of shares of common stock and common 
stock equivalents outstanding, including those related to share-based compensation and convertible senior notes.  Earnings per share are 
computed  using  the  “treasury  stock  method.”    The  convertible  senior  notes  include  a  net  share  settlement  feature  which  requires  the 
Company to redeem the par amount of the note in cash and any remaining value, assuming the note is in-the-money, in incremental shares, 
cash, or a combination thereof. The net-share settled convertible, as structured, allows the Company to use the treasury stock method of 
calculating diluted earnings per share. The incremental value of the shares will be determined based on the average price of the Company’s 
common stock over the reporting period. There are no shares in the earnings per share calculation for the years ended December 31, 2010, 
2009 and 2008 related to the convertible senior notes as the average stock price did not exceed the conversion price and, therefore, there is 
no conversion spread.

Share-based  compensation  –  The  Company  uses  the  Black-Scholes-Merton  model  to  determine  the  fair  value  of  stock 
options on the date of grant and recognizes compensation expense for stock options on a straight-line basis.  Restricted stock  grants 
are measured based on the fair market value of the underlying stock on the date of grant and compensation expense for restricted stock 
grants is recognized on a straight-line basis over the requisite service period. In addition to the recognition of compensation expense, 
non-vested restricted stock grants are included in the diluted shares outstanding calculation. 

The amount of compensation expense recognized using the Black-Scholes-Merton model requires the Company to exercise 
judgment and make assumptions relating to the factors that determine the fair value of its stock option grants. The fair value calculated 
by this model is a function of several factors, including the grant price, the expected future volatility, the expected term of the option 
and  the  risk-free  interest  rate  of  the  option.  The  expected  term  and  expected  future  volatility  of  the  options  require  judgment.  In 
addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those stock options expected 
to vest.  The Company estimates the forfeiture rate based on historical experience, and to the extent its actual forfeiture rate is different 
from its estimate, share-based compensation expense is adjusted accordingly.   

Functional  currencies  and  foreign  currency  translation  –  The  functional  currency  for  most  of  the  Company’s 
international  operations  is  the  U.S.  dollar.    However,  some  of  its  subsidiaries  functional  currency  is  their  local  currency,  as  the 
Company believes it is the appropriate currency.  The Company believes the New Taiwan (“NT”) dollar is the functional currency at 
Diodes  Taiwan  Inc.  and  the  British  Pound  Sterling  (“GBP”)  is  the  functional  currency  at  Diodes  Zetex  Limited,  which  most 
appropriately reflects the current economic facts and circumstances of their operations. Assets and liabilities denominated in foreign 
currencies  are  translated  at  the  exchange  rate  on  the  balance  sheet  date.  Income  and  expense  accounts  denominated  in  foreign 
currencies  are  translated  at  the  weighted-average  exchange  rate  during  the  period  presented.  Resulting  translation  adjustments  are 
recorded as a separate component of accumulated other comprehensive income or loss within stockholders’ equity in the consolidated 
balance sheets.

 (Amounts in thousands except per share data) 

The Company uses the U.S. dollar as the functional currency in Diodes Hong Kong Limited, Shanghai Kai Hong Electronic 
Co., Ltd. and Shanghai Kai Hong Technology Co., Ltd. as substantially all monetary transactions are made in U.S. dollars, and other 
significant economic facts and circumstances currently support that position.  As these factors may change in the future, the Company 
periodically assesses its position with respect to the functional currency of its foreign subsidiaries.  Included in other income are foreign 
exchange losses of $0.4 million, $4.7 million and $6.7 million for the years ended December 31, 2010, 2009 and 2008, respectively. 

Defined benefit plan – The Company maintains pension plans covering certain of its employees in the U.K. and Germany.  For 
financial  reporting  purposes,  the  net  pension  and  supplemental  retirement  benefit  obligations  and  the  related  periodic  pension costs  are 
calculated based upon, among other things, assumptions of the discount rate for plan obligations, estimated return on pension plan assets 
and mortality rates.  These obligations and related periodic costs are measured using actuarial techniques and assumptions.  The projected 
unit credit method is the actuarial cost method used to compute the pension liabilities and related expenses.   

Asset retirement obligations – The Company recognizes assets retirement obligations (“ARO’s”) when incurred, with the initial 
measurement at fair value.  These liabilities are accreted to full value over time through charges to income.  In addition, asset retirement 
costs are capitalized as part of the related asset’s carrying value and are depreciated over the assets respective useful life. The Company’s 
ARO’s consist primarily of estimated costs to return leased property to its original condition.  As of December 31, 2010 and 2009, the 
liabilities of $0.3 million for ARO’s are included in the Company’s consolidated balance sheet as other long-term liabilities. 

Investment in joint ventures – Investment in joint ventures over which the Company does not have the ability to exercise 
significant influence and that, in general, are at least 20 percent owned are stated at cost plus equity in undistributed net income (loss) 
of  the  joint  venture.  These  investments  are  evaluated  for  impairment,  in  which  an  impairment  loss  would  be  recorded  whenever  a 
decline in the value of an equity investment below its carrying amount is determined to be “other than temporary.” In judging "other 
than temporary," the Company would consider the length of time and extent to which the fair value of the investment has been less 
than the carrying amount of the investment, the near-term and longer-term operating and financial prospects of the investee, and the 
Company's  longer-term  intent  of  retaining  the  investment  in  the  investee.    As  of  December  31,  2010  and  2009,  the  value  of  the 
Company’s investment in joint ventures of $1.2 million and $0.5 million, respectively, are included in the Company’s consolidated balance 
sheet as other assets.  

Contingencies  –  From  time  to  time,  the  Company  may  be  involved  in  a  variety  of  legal  matters  that  arise  in  the  normal 
course  of  business.    Based  on  information  available,  the  Company  evaluates  the  likelihood  of  potential  outcomes.  The  Company 
records the appropriate liability when the amount is deemed probable and reasonably estimable. In addition, the Company does not 
accrue for estimated legal fees and other directly related costs as they are expensed as incurred.  

Comprehensive income (loss) – GAAP generally requires that recognized revenue, expenses, gains and losses be included in net 
income.  Although certain changes in assets and liabilities are reported as separate components of the equity section of the consolidated 
balance  sheet,  such  items,  along  with  net  income,  are  components  of  comprehensive  income  or  loss.  The  components  of  other 
comprehensive income or  loss include foreign currency  translation adjustments, unrealized gain or loss on defined benefit plan, foreign 
currency gain (loss) on forward contracts and other items. Accumulated other comprehensive loss was $(45.1) million, $(48.3) million and 
$(48.4) million at December 31, 2010, 2009 and 2008, respectively.

Reclassifications – Certain amounts from prior periods have been reclassified to conform to the current years’ presentation.  

Recently issued accounting pronouncements – In April 2010, the Financial Accounting Standards Board (“FASB”) issued 
Accounting Standards Update (“ASU”) No. 2010-13, Compensation – Stock Compensation (Topic 718): Effect of Denominating the 
Exercise Price of a Share-Based Payment Award in the Currency of the Market in which the Underlying Equity Security Trades. ASU 
No. 2010-13 clarifies that an employee share-based payment award with an exercise price denominated in the currency of a market in 
which a substantial portion of the entity’s equity shares trades  should not be considered to contain a condition that is not a  market, 
performance,  or  service  condition.  Therefore,  an  entity  would  not  classify  such  an  award  as  a  liability  if  it  otherwise  qualifies  as 
equity. The provisions of ASU No. 2010-13 are effective for fiscal years, and interim periods within those fiscal years, beginning on 
or after December 15, 2010. Early adoption is permitted. The Company does not expect the adoption of this ASU to have a material 
impact on its consolidated financial statements. 

In April 2010, the FASB issued ASU No. 2010-17, Revenue Recognition - Milestone Method (Topic 605): Milestone Method 
of Revenue Recognition (A consensus of the FASB Emerging Issues Task Force). ASU No. 2010-17 provides guidance on defining a 
milestone  and  determining  when  it  may  be  appropriate  to  apply  the  milestone  method  of  revenue  recognition  for  research  or 
development transactions. The amendments provide guidance on the criteria that should be met for determining whether the milestone 
method  of  revenue  recognition  is  appropriate.  An  entity  can  recognize  consideration  that  is  contingent  upon  achievement  of  a 
milestone in its entirety as revenue in the period in which the  milestone was achieved only if the milestone meets all criteria to be 
considered  substantive.  The  provisions  of  ASU  No.  2010-17  are  effective  on  a  prospective  basis  for  milestones  achieved  in  fiscal 
years, and interim periods within those years, beginning on or after June 15, 2010. Early adoption is permitted. The Company does not 
expect the adoption of this ASU to have a material impact on its consolidated financial statements. 

In  December  2010,  the  FASB  issued  ASC  No.  2010-28,  Intangibles—Goodwill  and  Other  (Topic  350):  When  to  Perform 
Step  2  of  the  Goodwill  Impairment  Test  for  Reporting  Units  with  Zero  or  Negative  Carrying  Amounts  (a  consensus  of  the  FASB 
Emerging Issues Task Force).  ASU No. 2010-28 addresses questions about entities that have reporting units with zero or negative 
carrying amounts. The amendments modify Step 1 of the goodwill impairment test for reporting units with zero or negative carrying 
amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not 
that a goodwill impairment exists. In determining whether it is more likely than not that goodwill impairment exists, an entity should 
consider whether there are any adverse qualitative factors indicating that impairment may exist. The qualitative factors are consistent

with  the  existing  guidance  and  examples  in  paragraph  350-20-35-30,  which  requires  that  goodwill  of  a  reporting  unit  be  tested  for 
impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a 
reporting unit below its carrying amount. In addition, current GAAP will be improved by eliminating an entity’s ability to assert that a 
reporting  unit  is  not  required  to  perform  Step  2  because  the  carrying  amount  of  the  reporting  unit  is  zero  or  negative  despite  the 
existence of qualitative factors that indicate the goodwill is more likely than not impaired. As a result, goodwill impairments may be 
reported  sooner  than  under  current  practice.  The  provisions  of  ASC  No.  2010-28  are  effective  for fiscal  years,  and  interim  periods 
within those years, beginning after Dec. 15, 2010. Early adoption is not permitted. The Company does not expect the adoption of this 
ASU to have a material impact on its consolidated financial statements. 

In December 2010, the FASB issued ASU No. 2010-29, Business Combinations (Topic 805) — Disclosure of Supplementary 
Pro  Forma  Information  for  Business  Combinations.  ASU  No.  2010-29  clarifies  that,  when  presenting  comparative  financial 
statements,  SEC  registrants  should  disclose  revenue  and  earnings  of  the  combined  entity  as  though  the  current  period  business 
combinations  had  occurred  as  of  the  beginning  of  the  comparable  prior  annual  reporting  period  only.  The  amendments  expand  the 
supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments 
directly attributable to the business combination included in the reported pro forma revenue and earnings. ASU 2010-29 is effective 
prospectively for material (either on an individual or aggregate basis) business combinations entered into in fiscal years beginning on 
or after December 15, 2010 with early adoption permitted.  The Company is currently in the process of determining the impact, if any, 
of the adoption of the ASU on its consolidated financial statements.

NOTE 2 – BUSINESS ACQUISITIONS  

Zetex Acquisition – On June 9, 2008, the Company completed the acquisition of all the outstanding ordinary capital stock of 
Zetex plc (“Zetex”), a company incorporated under the laws of England and Wales.  The Zetex shareholders received 85.45 pence in 
cash  per  ordinary  share,  valuing  the  fully  diluted  share  capital  of  Zetex  at  approximately  $176.1  million  (based  on  a  USD:GBP 
exchange rate of 1.9778), excluding acquisition costs, fees and expenses. 

As consideration for Zetex, the Company paid the following:

In  addition,  in  order  to  finance  the  acquisition,  the  Company  entered  into  a  margin  loan  agreement  with  UBS  Financial 
Services Inc. for $165 million, collateralized by the Company’s ARS portfolio.  On November 4, 2008, the Company entered into a no 
net cost credit line (“no net cost”) loan, which replaced the margin loan. On June 30, 2010, the Company fully repaid the “no net cost” 
loan.  See Note 10 for additional information. 

The results of operations of the Zetex acquisition have been included in the consolidated financial statements from June 1, 
2008. The purpose of this acquisition was to create revenue, operating and cost synergies and to enhance the Company’s leadership in 
discrete and analog solutions.  In addition, the Company believes that the acquisition will strengthen and broaden its product offerings, 
including  entry  into  the  LED  lighting  and  automotive  markets  and  expand  the  Company’s  geographical  footprint  in  the  European 
markets. 

The  following  table  summarizes  the  allocation  of  the  purchase  price  to  the  fair  value  of  the  assets  acquired  and  liabilities

Subsequent to the acquisition, the Company evaluated and adjusted its inventory for a reasonable profit allowance, which is 
intended to permit the Company to report only the profits normally associated with its activities following the acquisition as it relates 
to  the  work-in-progress  and  finished  goods  inventory.    As  such,  the  Company  increased  its  acquired  inventory  from  Zetex  by 
approximately $5.4 million, and subsequently recorded that increase, adjusted for foreign exchange rates, into cost of goods sold in the 
amount of approximately $5.2 million during 2008. 

Acquired intangible in process research and development (“IPR&D”), which had not yet reached technological feasibility and 
had  no  alternative  future  use  as  of  the  date  of  acquisition  in  the  amount  of  $7.9  million  was  expensed  immediately  in  2008,  in 
accordance  with  SFAS  No.  141,  to  research  and  development.    IPR&D  consists  of:  (i)  power  management,  which  includes  power 
management chips that meet the requirements of a broad range of portable electronic equipment that demands a balance of efficiency, 
functionality, and size; (ii) lighting, which includes LED drivers that are developed for a range of applications including white LEDs 
for display backlighting, safety and security lighting, camera flash, architectural lighting, and automotive lighting, which maintains 
illumination  while  limiting  battery  power  consumption;  and  (iii)  other,  including  items  such  as  audio,  which  includes  class  D 
amplifiers  that  efficiently  deliver  high  quality  audio.    The  risk  adjusted  discount  rate  used  to  determine  the  fair  value  of  power 
management, lighting and other was 26%, 28% and 28%, respectively. 

Amortization expense associated with identified intangible assets will approximate between $1.8 million and $3.8 million per 

year over the next 5 to 10 years. In addition, the Company expects goodwill to be deductible for tax purposes.

NOTE 3 – FOREIGN CURRENCY HEDGING  

As a multinational Company, sales transactions are denominated in a variety of currencies. In connection with the acquisition 
of  Zetex,  the  Company  acquired  forward  exchange  contracts,  designated  as  foreign-currency  cash  flow  hedges,  to  reduce  the 
potentially adverse effects of foreign-currency exchange rate fluctuations that occur from sales denominated in currencies other than 
the  GBP,  which  is  the  functional  currency  of  Zetex.    The  Company  used  these  forward  exchange  contracts  to  hedge,  thereby 
attempting to reduce the Company’s overall exposure to the effects of currency fluctuations on cash flows. The Company does not 
permit speculation in financial instruments for profit on the exchange rate price fluctuation, trading in currencies for which there are 
no underlying exposures, or entering into trades for any currency to intentionally increase the underlying exposure.  

As of December 31, 2009, the Company no longer held forward contracts as they matured during 2009.  Additionally, for all 
periods  presented,  there  was  no  significant  impact  on  results  of  operations  from  discontinued  cash  flow  hedges  as  a  result  of 
forecasted transactions that did not occur.

NOTE 4 – FAIR VALUE MEASUREMENTS 

Fair  value  is  the  price  that  would  be  received  to  sell  an  asset or  paid  to  transfer  a  liability  in  an  orderly  transaction  between 
market  participants  at  the  measurement  date.  A  fair  value  measurement  assumes  that  the  transaction  to  sell  the  asset  or  transfer  the 
liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for 
the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability shall 
not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the 
measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is 
not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, 
(iii) able to transact and (iv) willing to transact.  

The  Company  uses  valuation  techniques  that  are  consistent  with  the  market  approach,  the  income  approach  and/or  the  cost 
approach.  The  market  approach  uses  prices  and  other  relevant  information  generated  by  market  transactions  involving  identical  or 
comparable  assets  and  liabilities.  The  income  approach  uses  valuation  techniques  to  convert  future  amounts,  such  as  cash  flows  or 
earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to 
replace  the  service  capacity  of  an  asset  (replacement  costs).  Valuation  techniques  should  be  consistently  applied.  Inputs  to  valuation 
techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning 
those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained 
from  independent  sources,  or  unobservable,  meaning  those  that  reflect  the  reporting  entity’s  own  assumptions  about  the  assumptions 
market  participants  would  use  in  pricing  the  asset  or  liability  developed  based  on  the  best  information  available  in  the  circumstances. 
These  two  types  of  inputs  create  a  three-tier  fair  value  hierarchy  that  gives  the  highest  priority  to  quoted  prices  in  active  markets  for 
identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:  

Level  1  Inputs  -  Unadjusted  quoted  prices  in  active  markets  for  identical  assets  or  liabilities  that  the  reporting  entity  has  the 

ability to access at the measurement date. 

Level 2 Inputs - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or 
indirectly. These include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or 
liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (for example, interest 
rates,  volatilities,  prepayment  speeds,  loss  severities,  credit  risks  and  default  rates)  or  inputs  that  are  derived  principally  from  or 
corroborated by observable market data by correlation or other means.  

Level 3 Inputs - Significant unobservable inputs that reflect an entity’s own assumptions that market participants would use in 

pricing the assets or liabilities. 

Due  to  lack  of  observable  market  quotes  on  the  Company’s  ARS  portfolio  and  “put”  option,  the  fair  value  measurements 
were estimated using Level 3 inputs.  The fair value was based on factors that reflect assumptions market participants would use in 
pricing, including, among others: relevant future market conditions including those that are based on the expected cash flow streams, 
the underlying financial condition and credit quality of the issuer and bond insurer, the percent of the Federal Family Education Loan 
Program (“FFELP”) guaranty, and the maturity of the securities, as well as the market activity of similar securities. The valuation of 
the Company’s ARS investment portfolio was subject to uncertainties that are difficult to predict and the future actual market prices 
may differ materially. See Note 5 for additional information regarding the Company’s ARS portfolio. 

On  October  29,  2008,  the  Company  reached  a  settlement  with  UBS  AG  and  affiliates  (“UBS  AG”),  in  regard  to  its  ARS 
portfolio, which gives the Company the option to “put” the ARS portfolio back to UBS AG at anytime during June 30, 2010 and July 
2, 2012 at par value. The “put” option does not meet the definition of a derivative as the terms of the “put” option do not provide for 
net settlement as the Company must tender the ARS portfolio to receive the settlement and the ARS portfolio is not readily convertible 
to cash. Upon settlement, the Company elected the fair value option for the “put” option. Upon initial recognition of the “put” option, 
the Company recorded an asset and a gain for the fair value of the “put” option. Until the Company exercises its “put” option, it will 
adjust  the  fair  value  on  a  quarterly  basis  with  corresponding  changes  in  fair  value  to  be  reported  in  the  consolidated  statements  of 
income. 

Given  that  the  “put”  option  was  a  free  standing  instrument  and  the  rights  are  not  transferable,  the  existence  of  the  “put” 
option did not affect the separate determination of the fair value of the ARS portfolio since the price a market participant would be 
willing  to  pay  for  the  ARS  portfolio  would  not  include  the  “put”  option.  Therefore,  the  “put”  option  cannot  be  considered  in 
determining the value of the ARS portfolio.

Upon  reaching  settlement  with  UBS  AG,  the  Company  transferred  its  ARS  portfolio  from  an  available-for-sale  securities 
category  to  trading  securities  category.    Although  transfers  into  trading  securities  should  be  rare,  the  Company  believes  that  the 
unprecedented  failure  of  the ARS  market  and  its  settlement  with  UBS AG  meets  the  conditions  for  such  a  rare  transfer. When  the 
Company  made  the  transfer,  all  of  the  previously  recorded  unrealized  losses  in  comprehensive  income  were  included  in  the 
consolidated statement of income.  

Since  the  Company  elected  to  transfer  its  ARS  portfolio  from  available-for-sale  securities  category  to  trading  securities 
category  and  made  the  fair  value  election  for  the  “put”  option,  all  fair  value  changes  for  both  were  included  in  the  consolidated 
statements of income, thereby creating accounting symmetry at both inception of the settlement and until the Company exercised its 
“put” option.  See Notes 5 and 10 for additional information regarding the Company’s settlement with UBS AG. 

On June 30, 2010, the Company put back its ARS portfolio to UBS AG at par value pursuant to the settlement agreement 
with UBS AG.  Upon exercise of the put option, the Company liquidated its ARS, for cash and used the proceeds to fully repay the 
related “no net cost” loan with UBS Bank. 

Financial assets and liabilities carried at fair value as of December 31, 2009 are classified in the following tables:

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are 
not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when 
there  is  evidence  of  impairment).  Financial  assets  and  financial  liabilities  measured  at  fair  value on  a  non-recurring  basis  were  not 
significant  at  December  31,  2010  and  2009.    Certain  non-financial  assets  and  non-financial  liabilities  measured  at  fair  value  on  a 
recurring and non-recurring basis include goodwill, other intangible assets and other non-financial long-lived assets.

As of December 31, 2009, the Company had $296.6 million invested in ARS, which were instruments that provided liquidity 
through  a  Dutch  auction  process  that  resets  the  applicable  interest  rate  at  pre-determined  calendar  intervals.  These  mechanisms 
historically have allowed existing investors to roll over their holdings and continue to own the respective securities or to liquidate their 
holdings by selling their securities at par value. 

Historically, the Company invested in ARS for short periods of time as part of its cash management program. However, in 
2008,  due  to  uncertainties  in  the  credit  markets  and  the  failure  of  the  auctions  for  the  Company’s  ARS,  the  Company  and  other 
investors  were  prevented  from  liquidating  holdings  of  ARS.  An  auction  failure,  which  is  not  a  default  in  the  underlying  debt 
instrument, occurs when the amount of securities submitted for sale exceeds the amount of purchase orders.  

On October 29, 2008, the Company reached a settlement with UBS AG.  As part of the settlement, the Company transferred 
its ARS portfolio from available-for-sale securities category to trading securities category.  Although transfers into trading securities 
should  be  rare,  the  Company  believes  that  the  unprecedented  failure  of  the  ARS  market  and  its  settlement  with  UBS  AG  met  the 
conditions  for  such  a  rare  transfer.  When  the  Company  made  the  transfer  all  of  the  previously  recorded  unrealized  losses  in 
comprehensive income, it transferred the losses to the consolidated statement of income.  

In connection with the settlement with UBS AG the Company was given the option to “put” the ARS portfolio back to UBS 
AG at anytime during June 30, 2010 and July 2, 2012 at par value. The “put” option was a free standing instrument and the rights are 
not transferable.  Upon settlement, the Company elected the fair value option for the “put” option and recorded an asset and a gain for 
the fair value of the “put” option.  As of December 31, 2009, the “put” option was classified as a short-term investment as it was a free 
standing instrument tied to the ARS portfolio, which were also classified as short-term investments. In addition, as of December 31, 
2009, the Company’s portfolio of ARS were valued using a valuation model that relied exclusively on Level 3 inputs.  See Note 4 for 
additional information regarding fair value measurements of the Company’s ARS portfolio and put option. 

On June 30, 2010, the Company put back its ARS portfolio to UBS AG at par value pursuant to the settlement agreement 
with UBS AG.  Upon exercise of the put option, the Company liquidated its ARS, for cash and used the proceeds to fully repay the 
related “no net cost” loan with UBS Bank.

NOTE 10 – BANK CREDIT AGREEMENTS AND OTHER SHORT-TERM AND LONG-TERM DEBT 

Lines of credit – The Company maintains credit facilities with several financial institutions through its entities in the U.S., 
Asia and Europe totaling $50 million.  On November 25, 2009 the Company entered into a credit agreement with Bank of America, 
N.A. (“Bank of America”) as modified by a certain letter dated as of March 31, 2010, the First Amendment to Credit Agreement dated 
as of July 16, 2010, the Second Amendment to Credit Agreement dated as of November 24, 2010 and the Third Amendment to Credit 
Agreement  dated  as  of  February  4,  2011  (collectively  the  “Credit  Agreement”).    The  Credit  Agreement  provides  for  a  $10  million 
revolving  credit  facility  (the  “Revolver”)  and  a  $10  million  uncommitted  facility  (the  “Uncommitted  Facility”).    The  Revolver 
includes a $1.5 million sublimit for letters of credit. Both the Revolver and the Uncommitted Facility mature on November 23, 2011 
(the “Maturity Date”). Any borrowing and obligations under the Revolver or under the Uncommitted Facility is secured by accounts, 
chattel paper, deposit accounts and inventory, and all dividends, distributions, and income attributable to proceeds, products, additions 
to, substitutions, replacements and supporting obligations for, model conversions, and accessions of the foregoing, of the Company 
and of certain of its subsidiaries.  Certain subsidiaries of the Company also guaranty any borrowing and obligations and pledge their 
interests to Bank of America in certain subsidiary stock owned by such subsidiary guarantors. 

In  addition,  the  Credit  Agreement  contains  certain  restrictive  and  financial  covenants,  including,  but  not  limited  to,  the 
following: (a) the Company shall maintain on a consolidated basis a Fixed Charge Coverage Ratio of not less than 2.00 to 1.0 and a 
Quick Ratio of not less than 1.50 to 1.0 (excluding the Company’s Notes for both ratios); (b) the Company and its subsidiaries shall 
not  create,  incur,  assume  or  suffer  to  exist  any  lien  upon  any  of  its  property,  assets  or  revenues  except  as  specified  in  the  Credit 
Agreement; (c) the Company and its subsidiaries shall not make any investments except as specified in the Credit Agreement; (d) the 
Company  and  its  subsidiaries  shall  not  create,  incur,  assume  or  suffer  to  exist  any  indebtedness  except  as  specified  in  the  Credit 
Agreement;  (e)  the  Company  and  its  subsidiaries  shall  not  dissolve  or  merge  or  consolidate  with  or  into  another  entity  except  as 
specified  in  the  Credit  Agreement;  (f)  the  Company  and  its  subsidiaries  shall  not  make  any  disposition  except  as  specified  in  the 
Credit Agreement; (g) the Company and its subsidiaries shall not make any restricted payment, or issue or sell any equity interests, 
except as specified in the Credit Agreement; (h) the Company and its subsidiaries shall not engage in any material line of business 
substantially different from those lines of business that are currently conducted by the Company and its subsidiaries; (i) the Company 
and its subsidiaries shall not enter into any transaction of any kind with any affiliate of the Company except as specified in the Credit 
Agreement; (j) the Company and its subsidiaries shall not enter into certain burdensome contractual obligations except as specified in 
the Credit Agreement; and (k) the Company and its subsidiaries shall not use the proceeds of any credit extension to purchase or carry 
margin stock or to extend credit to others for the purpose of purchasing or carrying margin stock or to refund indebtedness originally 
incurred for such purpose.  As of December 31, 2010, the Company was in compliance with these covenants. 

The credit unused and available under the various facilities as of December 31, 2010, was $46.7 million (net of $3.3 million 

credit used for import and export guarantee), as follows:

Convertible senior notes – On October 12, 2006, the Company issued and sold convertible senior notes with an aggregate 
principal amount of $230 million due 2026 (the “Notes”), which pays 2.25% interest per annum on the principal amount of the Notes, 
payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 1, 2007. Interest will accrue on the Notes 
from and including October 12, 2006 or from and including the last date in respect of which interest has been paid or provided for, as 
the case may be, to, but excluding, the next interest payment date or maturity date, as the case may be. Commencing with the six-
month period beginning October 1, 2011, and for each six-month period thereafter, the Company will, on the interest payment date for 
such interest period, pay contingent interest to the holders of the Notes under certain circumstances and in amounts described in the 
indenture. For U.S. Federal income tax purposes, the Company will treat, and each holder of the Notes will agree under the indenture 
to  treat,  the  Notes  as  contingent  payment  debt  instruments  governed  by  special  tax  rules  and  to  be  bound  by  the  Company’s 
application of those rules to the Notes. 

On each of October 1, 2011, October 1, 2016 and October 1, 2021, holders may require the Company to purchase all or a 
portion of their Notes at a purchase price in cash equal to 100% of the principal amount of the Notes to be purchased, plus any accrued 
and unpaid interest to, but excluding, the purchase date.  Therefore, during the fourth quarter of 2010, the Company reclassified its 
Notes from long-term debt to current liabilities. Should the holders choose to require the Company to purchase their Notes on October 
1, 2011, the Company will be required to use available funds and/or seek alternative means to service the debt. 

In addition, note holders may require the Company to repurchase all or a portion of its Notes upon a fundamental change, as 
described in the prospectus, at a repurchase price in cash equal to 100% of the principal amount of the Notes to be repurchased, plus 
any accrued and unpaid interest to, but excluding, the fundamental change repurchase date. Future minimum interest payments related 
to the Notes as of December 31, 2010 are $3.0 million for each year from 2011 through 2015. Future minimum payments related to 
the Notes as of December 31, 2010 for 2016 and thereafter include $17.4 million in interest and $134.3 million in principal for a total 
of $151.7 million. 

In  certain  circumstances,  the  Notes  are  convertible  into  cash  or,  at  the  Company’s  option,  cash  and/or  shares  of  the 
Company’s common stock based on an initial conversion rate, subject to adjustment, of 25.6419 shares per $1,000 principal amount of 
Notes,  which  represents  an  initial  conversion  price  of  $39.00  per  share  (split  adjusted).  In  addition,  following  a  “make-whole 
fundamental change” that occurs prior to October 1, 2011, the Company will, at its option, increase the conversion rate for a holder 
who elects to convert its Notes in connection with such “make-whole fundamental change,” in certain circumstances. 

Note holders may convert their Notes prior to stated maturity only under the following circumstances: (i) during any calendar 
quarter after the calendar quarter ending December 31, 2006, if the closing sale price of the Company’s common stock for each of 20 
or more trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar 
quarter  exceeds  120%  of  the  conversion  price  in  effect  on  the  last  trading  day  of  the  immediately  preceding  calendar  quarter;  (ii) 
during the five consecutive business days immediately after any five consecutive trading day period (the Company refers to this five 
consecutive trading day period as the “note measurement period”) in which the average trading price per $1,000 principal amount of 
Notes was equal to or less than 98% of the average conversion value of the Notes during the note measurement period; (iii) upon the 
occurrence  of  specified  corporate  transactions;  (iv)  if  the  Company  calls  the  Notes  for  redemption;  and  (v)  at  any  time  from,  and 
including,  September  1,  2011  to,  and  including,  October  1,  2011  and  at  any  time  on  or  after  October  1,  2024.  Upon  conversion, 
holders  will  receive  cash,  or  at  the  Company’s  option,  cash  and  shares  of  the  Company’s  common  stock  based  on  the  conversion 
payment terms described in the Note. The conversion obligation is based on the sum of the “daily settlement amounts” described in 
the  prospectus  for  the  20  consecutive  trading  days  that  begin  on,  and  include,  the  second  trading  day  after  the  day  the  Notes  are 
tendered for conversion.

On or after October 1, 2011, the Company may, from time to time, at its option, redeem the Notes, in whole or in part, for 
cash, at a redemption price equal to 100% of the principal amount of the Notes the Company redeems, plus any accrued and unpaid 
interest to, but excluding, the redemption date. 

The Company has evaluated the terms of the call feature, redemption feature, and the conversion feature under applicable

“No Net Cost” Loan 

In connection with the acquisition of Zetex, the Company entered into a $165 million interest-bearing margin loan with UBS 
Financial  Services,  Inc.,  secured  by  the  Company’s  ARS  portfolio.    See  Note  2  for  additional  information  regarding  the  Zetex 
acquisition.   

On November 4, 2008, the Company accepted an offer of a “no net cost” loan, which replaced the margin loan, from UBS 
BANK USA (“UBS Bank”), an affiliate of UBS AG and was collateralized by the Company’s ARS portfolio.  Under the “no net cost” 
loan, UBS Bank will not make an advance against the ARS collateral in amounts equal to the fair market or par value of the ARS 
collateral  unless  the  Company  arranges  for  another  person  or  entity  to  provide  additional  collateral  or  assurances  on  terms  and 
conditions satisfactory to the UBS Bank.  In addition, UBS Bank may demand full or partial payment or terminate and cancel the “no 
net cost” loan, at its sole option and without cause, at any time.   However, If at any time UBS Bank exercises its right of demand 
under  certain  sections  of  the  Credit  Line  Agreement,  UBS  Financial  Services,  Inc.  shall  provide  as  soon  as  reasonably  possible, 
alternative financing on substantially the same terms and conditions as those under the Credit Line Agreement and UBS Bank agrees 
that the Credit Line Agreement shall remain in full force and effect until such time as such alternative financing has been established.  
If alternative financing cannot be established, then one of the UBS Entities will purchase the pledged ARS at par.  Furthermore, if the

Company elects to sell any ARS that are pledged as collateral under the Credit Line Agreement with UBS Bank to a purchaser other 
than UBS Bank, UBS Bank intends to exercise its right to demand repayment of the “no net cost” loan relating to the ARS sold by the 
Company. 

The “no net cost” loan allowed the Company to draw up to 75% of the market value of its ARS portfolio, as determined by 
the UBS Bank, which is subject to collateral maintenance requirements. Under the “no net cost” loan, the interest rate the Company 
pays on the “no net cost” loan will not exceed the interest rate earned on the pledged ARS portfolio.  Subsequent to the agreement, the 
Company drew up to the 75% market value limit, as determined by UBS.  On November 10, 2009, the Company received a credit line 
of up to the full par value of its ARS portfolio.  Subsequently, the Company drew up to the full value or $296.6 million of the credit 
line.  As of December 31, 2009, the balance of the “no net cost” loan was $296.6 million and classified as short-term debt.  

On June 30, 2010, the Company put back its ARS portfolio to UBS AG at par value pursuant to the settlement agreement 
with UBS AG.  Upon exercise of the put option, the Company liquidated its ARS, for cash and used the proceeds to fully repay the 
related “no net cost” loan with UBS Bank.

NOTE 13 – STOCKHOLDERS’ EQUITY 

As  of  December  31,  2010,  the  Company  had  approximately  44.7  million  common  shares  outstanding.  During  2010,  shares 

outstanding increased by approximately 1.0 million shares, primarily due to shares issued in conjunction with share-based plans. 

Additional  paid-in  capital  increased  approximately  $20.0  million  in  the  year  ended  December  31,  2010,  primarily  due  to 
approximately $13.1 million in share-based compensation expense and approximately $7.2 million in conjunction with issuing shares 
related to share-based plans.   

The Company’s credit agreement with Bank of America permits the Company to pay dividends to its stockholders so long as 
it is not in default and is in continuing operation at the time of such dividend.  The payment of dividends is within the discretion of the 
Company’s  Board  of  Directors,  and  will  depend  upon,  among  other  things,  the  Company’s  earnings,  financial  condition,  capital 
requirements, and general business conditions.  See Note 10 for additional information regarding the Company’s credit agreements. 

NOTE 14 – RESTRUCTURING COSTS  

In  the  year  ended  December  31,  2008,  the  Company  recorded  approximately  $4.1  million  in  restructuring  costs  mainly 
relating  to  the  reduction  of  its  European  workforce  at  its  U.K.  operations  in  Oldham  of  which  accounted  for  approximately  $3.0 
million  and  to  a  lesser  extent  workforce  reductions  at  its  manufacturing  operations  in  China.    The  expense  primarily  consisted  of 
termination and severance costs. The restructuring was completed during the first quarter of 2009.

DIODES INCORPORATED AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
 (Amounts in thousands except per share data) 

For the year ended December 31, 2008, the Company reported domestic and foreign pre-tax income/(loss) of $(19.1) million and 
$47.5 million, respectively, including $14.3 million of deductions relating to purchase accounting adjustments from the Zetex acquisition 
for IPR&D, inventory adjustment for reasonable profit allowance and amortization of acquisition-related intangible assets.  For the year 
ended  December  31,  2009,  the  Company  reported  domestic  and  foreign  pre-tax  income  (loss)  of  $(46.8)  million  and  $57.9  million, 
respectively.  For the year ended December 31, 2010, the Company reported domestic and foreign pre-tax income (loss) of $(31.9) million 
and $130.0 million, respectively.   

The Company’s global presence requires the Company to pay income taxes in a number of jurisdictions. In general, earnings in 
the U.S. are currently subject to tax rates of 35%.  Earnings in Taiwan and Hong Kong are also subject to U.S. taxes with respect to those 
earnings that are derived from product manufactured by the Company’s China subsidiaries and sold to customers outside of Taiwan and 
Hong  Kong.  The  U.S. tax  rate  on  this  Subpart  F  income  is  computed  as  the  difference  between  the  foreign  effective  tax  rates  and  the 
U.S. tax rate. In accordance with U.S. tax law, the Company receives credit against the Company’s U.S. tax liability for income taxes paid 
by its foreign subsidiaries.   

Earnings in Hong Kong are subject to a 16.5% tax for local sales or local source sales; all other Hong Kong sales are not subject to 
foreign income taxes.  In Taiwan, earnings are subject to 20% in 2009 and 17% income tax rate thereafter.  In addition, Taiwan earnings are 
subject to an additional 10% retained earnings tax should the Taiwan earnings not be distributed.  As an incentive for the formation of 
Anachip Corp., its earnings are subject to a five-year tax holiday (subject to certain qualifications of Taiwanese tax law). In the third quarter 
of 2006, the Company elected to begin this five-year tax holiday as of January 1, 2006.  

In June 2008, the Company completed the acquisition of all the outstanding ordinary capital stock of Zetex.  Zetex’s earnings 
in the U.K. are currently subject to a tax rate of 28% and its earnings in Germany are subject to a 30% tax rate.  In addition, its U.K. 
earnings are also subject to U.S. income taxes less a credit for U.K. income taxes paid. For 2011, the Company expects a U.K. tax rate 
of 27%. 

The recent China government income tax reform increased the corporate income tax rate in China to 25% beginning in 2008.  
The earnings of Shanghai Kai Hong Technology Co., Ltd., which is located in the Songjiang Export Zone of Shanghai, China, were 
subject to a preferential tax rate of 7.5% in 2007, and 12.5% in both 2008 and 2009.  Due to its qualification as a high technology 
company,  the earnings of  Shanghai  Kai Hong  Electronic  Co.,  Ltd. were  subject  to  a preferential  tax rate  of 12%  in  2007  and 15% 
thereafter.  For 2011, the Company expects a tax rate of 15% for both subsidiaries. 

The  impact  of  tax  holidays  decreased  the  Company’s  tax  expense  by  approximately  $8.4  million,  $7.4  million  and  $6.6 
million for the years ended December 31, 2010, 2009 and 2008, respectively.  The benefit of the tax holidays on both basic and diluted 
earnings  per  share  for  the  year  ended  December  31,  2008  was  approximately  $0.16.    The  benefit  of  the  tax  holidays  on  basic  and 
diluted earnings per share for the year ended December 30, 2009 was approximately $0.17.  The benefit of the tax holidays on basic 
and diluted earnings per share for the year ended December 30, 2010 was approximately $0.19 and $0.18, respectively.   

The  Company  files  income  tax  returns  in  the  U.S.  federal  jurisdiction  and  in  various  state  and  foreign  jurisdictions.  The 
Company is no longer subject to U.S. federal income tax examinations by tax authorities for tax years before 2007.  With respect to 
state and local jurisdictions and countries outside of the U.S., with limited exceptions, the Company is no longer subject to income tax 
audits for years before 2006.  Although the outcome of tax audits is always uncertain, the Company believes that adequate amounts of 
tax, interest and penalties, if any, have been provided for in the Company’s reserve for any adjustments that may result from future tax 
audits. The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

In accordance with the provisions related to accounting for uncertainty in income taxes, the Company recognizes the impact 
of a tax position if the position is “more likely than not” to prevail upon examination by the relevant tax authority.  A reconciliation of 
the beginning and ending amount of unrecognized tax benefits is as follows: 

Balance at January 1, 
Additions based on tax positions related to the current year 
Reductions for prior years tax positions 
Balance at December 31,

2009 
$ 3,706

 (577) 
$ 8,064 

It is reasonably possible that the amount of the unrecognized benefit with respect to certain of the Company’s unrecognized tax 
positions will significantly increase or decrease within the next 12 months. These changes may be the result of settlements of ongoing 
audits or competent authority proceedings. At this time, an estimate of the range of the reasonably possible outcomes cannot be made. 

At December 31, 2010 and 2009, the Company’s deferred tax assets and liabilities are comprised of the following items: 

Deferred tax assets, current 
   Inventory cost 
   Accrued expenses and accounts receivable

Funds repatriated from foreign subsidiaries to the U.S. may be subject to federal and state income taxes.  The Company intends 
to  permanently  reinvest  overseas  all  of  its  earnings  from  its  foreign  subsidiaries;  accordingly,  U.S.  taxes  are  not  being  recorded  on 
undistributed  foreign  earnings.    As  of  December  31,  2010,  the  Company  has  undistributed  earnings  from  its  non-U.S.  operations  of 
approximately  $254  million  (including  approximately  $27  million  of  restricted  earnings  which  are  not  available  for  dividends).  
Additional federal and state income taxes of approximately $44 million would be required should such earnings be repatriated to the U.S. 

At December 31, 2010, the Company had federal and state tax credit carryforwards available to offset future regular income and 
partially offset alternative minimum taxable income of approximately $18.5 million and $0.7 million, respectively. The federal tax credit 
carryforwards began to expire in 2011 and the state tax credit carryforwards will begin to expire in 2020.  The Company determined that 
it  was  more  likely  than  not  that  a  portion  of  its  federal  foreign  tax  credit  carryforwards  would  expire  before  they  could  be  utilized.  
Accordingly,  the  Company  recorded  valuation  allowances  of  $2.3  million,  $3.9  million  and  $0.6  million  during  the  years  ended 
December 31, 2010, 2009 and 2008, respectively.   

At December 31, 2010, the Company had federal and state net operating loss (“NOL”) carryforwards of approximately $29.2 
million and $68.0 million, respectively, available to offset future regular and alternative minimum taxable income. The federal NOL 
carryforwards will begin to expire in 2018 and the state NOL carryforwards will begin to expire in 2013.  Furthermore, the Company 
determined that it was more likely than not that a portion of its federal and state net operating loss carryforwards would expire before 
they  could  be  fully  utilized  and  recorded  a  valuation  allowance  of  $1.8  million  during  the  year  ended  December  31,  2009.    The 
Company  subsequently  determined  that  the  loss  carryforwards  would  be  fully  utilized  and  reversed  the  $1.8  million  valuation 
allowance in 2010. 

The Company has unrecorded tax benefits related to the exercise of non-qualified stock options and the disqualified disposition 
of incentive stock options.  The tax benefits of approximately $14.8 million of NOLs related to stock option exercises in 2010, 2009 and 
2008 will be credited to additional paid-in capital when realized.  During 2010, the Company realized a tax benefit of $3.1 million related 
to stock option exercises which was credited to additional paid-in capital.  In addition, the Company has U.S. and U.K. tax benefits of 
$15.1 million, and an offsetting valuation allowance of approximately $15.1 million, related to its accrued pension liability that would be 
creditable to additional paid-in capital when realized.

NOTE 16 – EMPLOYEE BENEFIT PLANS 

Defined Benefit Plan 

In connection with the acquisition of Zetex, the Company has adopted a contributory defined benefit plan that covers certain 
employees  in  the  U.K.  and  Germany.    The  defined  benefit  plan  is closed  to  new  entrants  and  frozen  with  respect  to  future  benefit 
accruals.  The retirement benefit is based on the final average compensation and service of each eligible employee.  On the acquisition 
date, the Company determined the fair value of the defined benefit plan assets and utilizes an annual measurement date of December 
31. At subsequent measurement dates, defined benefit plan assets will be determined based on fair value. Defined benefit plan assets 
consist primarily of high quality corporate bonds that are denominated in the currency in which the benefits will be paid and that have 
terms  to  maturity  approximating  the  terms  of  the  related  pension  liability.    The  net  pension  and  supplemental  retirement  benefit 
obligations and the related periodic costs are based on, among other things, assumptions of the discount rate, estimated return on plan 
assets and mortality rates. These obligations and related periodic costs are measured using actuarial techniques and assumptions. The 
projected unit credit method is the actuarial cost method used to compute the pension liabilities and related expenses.  

Net period benefit costs associated with the defined benefit were approximately $1.4 million and $1.0 million for the year 
ended  December  31,  2010 and 2009,  respectively.  All  unrecognized  actuarial  gains  and  losses,  prior  service  costs  and  accumulated 
other comprehensive income are eliminated and the balance sheet liability is set equal to the funded status of the defined benefit plan 
at acquisition date. 

The following table summarizes the net periodic benefit costs of the Company’s plan for the years ended December 31, 2010 

and 2009:

Based on an actuarial study performed as of December 31, 2010, the plan is underfunded by approximately $24.9 million and 
the  liability  is  reflected  in  the  Company’s  consolidated  balance  sheets  as  a  noncurrent  liability  and  the  amount  recognized  in 
accumulated other comprehensive loss was approximately $15.9 million.  

The Company applies the “10% corridor” approach to amortize unrecognized actuarial gains (losses).  Under this approach, 
only actuarial gains (losses) that exceed 10% of the greater of the projected benefit obligation or the market-related value of the plan 
assets are amortized.  For the year ended December 31, 2010, the plans total recognized loss decreased by $3.6 million.  The variance 
between the actual and expected return to plan assets during 2010 decreased the total unrecognized net loss by $4.2 million.  The total 
unrecognized  net  loss  is  greater  than  10%  of  the  projected  benefit  obligation  or  10%  of  the  plan  assets.    The  excess  amount  will 
therefore be amortized over the average term to retirement of plan participants not yet in receipt of pension, which as of December 31, 
2010 the average term was 13 years.  The annual amortization amount is expected to be approximately $0.3 million per year.  

The following weighted-average assumptions were used to determine net periodic benefit costs for the year ended December

The expected long-term return on plan assets was determined based on historical and expected future returns of the various 
asset classes. The plans investment policy includes a mandate to diversify assets and invest in a variety of asset classes to achieve its 
expected long-term return and is currently invested in a variety of funds representing most standard equity and debt security classes.  
Trustees of the plan may make changes at any time. The following summarizes the plan asset allocations of the assets in the plan and 
expected long-term return by asset category:

The  Company  adopted  a  payment  plan  that  Zetex  had  in  place  with  the  trustees  of  the  defined  benefit  plan,  in  which  the 
Company will pay approximately ₤1.0 million GBP (approximately $1.6 million based on a USD:GBP exchange rate of 1.6:1) every 
year from 2009 through 2012. 

The Company’s overall defined benefit plan investment strategy is to achieve a mix of investments for long-term growth and 
for near-term benefit payments with a wide diversification of asset types and fund strategies.  The target allocations for plan assets are 
48% equity securities, 40% corporate bonds and government securities, and 12% to absolute return funds.  Equity securities primarily 
include  investments  in  large-cap  and  mid-cap  companies  primarily  located  in  the  U.K.    Fixed  income  securities  include  corporate 
bonds of companies from diversified industries, and U.K. government bonds. The absolute return fund is mainly invested in a mixture 
of equities and bonds.  

The plan’s trustees appoint fund managers to carry out all the day-to-day functions relating to the management of the fund 
and its administration. The fund managers must invest their portion of the plan’s assets in accordance with their investment manager 
agreement agreed by the trustees. The trustees are responsible for agreeing these investment manager agreements and for deciding on 
the portion of the plan’s assets that will be invested with each fund manager. When making decisions, the trustees take advice from 
experts including the plan’s actuary and also consult with the Company.

Fair  value  is  taken  to  mean  the  bid  value  of  securities,  as  supplied  by  the  fund  managers.  All  the  plan’s  securities  are 
publically traded and highly liquid.  Therefore, the majority of the securities are valued under Level 1 and one security is valued under 
Level 2 using quoted prices for identical or similar securities.  The plan does not hold any level 3 securities.  See Note 4 for additional 
information regarding fair value and Levels 1, 2 and 3. 

The investment manager agreements require the fund managers to invest in a diverse range of stocks and bonds across each 
particular asset class.  The stocks held by the plan in a particular asset class should therefore match closely the underlying stocks in the 
relevant index. The Company believes that this leads to minimal concentration of risk within each asset class; although it recognizes 
that some asset classes are inherently more risky than others. 

The Company also has pension plans in Asia for which the benefit obligation, fair value of the plan assets and the funded 

status amounts are deemed immaterial and therefore, not included in the amounts or assumptions above. 

401(k) Retirement Plan 

The  Company  maintains  a  401(k)  retirement  plan  (the  Plan)  for  the  benefit  of  qualified  employees  at  its  U.S.  locations. 
Employees who participate may elect to make salary deferral contributions to the Plan up to 100% of the employees’ eligible payroll 
subject  to  annual  Internal  Revenue  Code  maximum  limitations.  The  Company  makes  a  matching  contribution  of  $1  for  every  $2 
contributed by the participant up to 6% (3% maximum matching) of the participant’s eligible payroll, which vests over four years. In 
addition, the Company may make a discretionary contribution to the entire qualified employee pool, in accordance with the Plan. 

As stipulated by the regulations of the People’s Republic of China, the Company maintains a retirement plan pursuant to the 
local municipal government for the employees in China. The Company is required to make contributions to the retirement plan at  a 
rate  between  10%  and  22%  of  the  employee’s  eligible  payroll.  Pursuant  to  the  Taiwan  Labor  Standard  Law  and  Factory  Law,  the 
Company maintains a retirement plan for the employees in Taiwan, whereby the Company makes contributions at a rate of 6% of the 
employee’s eligible payroll. 

For the years ended December 31, 2010, 2009 and 2008, total amounts expensed under these plans were approximately $3.9 

million, $2.3 million and $2.0 million, respectively.

Deferred Compensation Plan 

The  Company  maintains  a  Non-Qualified  Deferred  Compensation  Plan  (the  “Deferred  Compensation  Plan”)  for  executive 
officers,  key  employees  and  members  of  the  Board  of  Directors  (the  “Board”).  The  Deferred  Compensation  Plan  allows  eligible 
participants to defer the receipt of eligible compensation, including equity awards, until designated future dates. The Company offsets 
its  obligations  under  the  Deferred  Compensation  Plan  by  investing  in  the  actual  underlying  investments.  These  investments  are 
classified  as  trading  securities  and  are  carried  at  fair  value.  At  December 31,  2010,  these  investments  totaled  approximately 
$3.2 million.  All  gains  and  losses  in  these  investments  are  equally  offset  by  corresponding  gains  and  losses  in  the  deferred 
compensation plan liabilities.  

Share-Based Plans 

The Company maintains share-based compensation plans for its Board, officers and key employees, which provide for stock 

options and stock awards under its 1993 ISO Plan, 1993 NQO Plan and 2001 Omnibus Equity Incentive Plan.

Stock Options – Stock options generally vest in equal annual installments over a four-year period and expire ten years after the 
grant date.  Share-based compensation expense for stock options granted during 2010, 2009 and 2008 was calculated on the date of grant 
using the following weighted-average forfeiture rates and the Black-Scholes-Merton option-pricing model using the following weighted-
average assumptions:

Expected volatility – The Company estimates expected volatility using historical volatility. Public trading volume on options in 
the  Company’s  stock  is  not  material.  As  a  result,  the  Company  determined  that  utilizing  an  implied  volatility  factor  would  not  be 
appropriate. The Company calculates historical volatility for the period that is commensurate with the option's expected term assumption. 
For  2010,  the  expected  volatility  for  grants  to  officers  and  the  Board  is  57.89%,  while  the  expected  volatility  for  grants  to  all  other 
employees is 58.84%. 

Expected  term  –  The  Company  has  evaluated  expected  term  based  on  history  and  exercise  patterns  across  its  demographic 
population. The Company believes that this historical data is the best estimate of the expected term of a new option. For 2010, the expected 
term for grants to officers and the Board is 7.6 years, while the expected term for grants to all other employees is 4.8 years. 

Risk free interest rate – The Company estimate the risk-free interest rate based on zero-coupon U.S. treasury securities for a period 

that is commensurate with the expected term assumption. 

Forfeiture rate - The amount of stock-based compensation recognized during a period is based on the value of the portion of 
the awards that are ultimately expected to vest as forfeitures are estimated at the time of grant and revised, if necessary, in subsequent 
periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinguished from “cancellations” or “expirations” 
and  represents  only  the  unvested  portion  of  the  surrendered  option.    This  analysis  will  be  re-evaluated  at  least  annually,  and  the 
forfeiture rate will be adjusted as necessary. 

Dividend yield – The Company historically has not paid a cash dividend; therefore this input is not applicable. 

Discount for post vesting restrictions – This input is not applicable. 

The  weighted-average  grant-date  fair  value  of  options  granted  during  2010,  2009  and  2008  was  $11.45,  $9.34,  and  $16.70, 
respectively. The total cash received from option exercises was $4.8 million, $1.5 million and $3.0 million during 2010, 2009 and 2008, 
respectively. 

For  the  years  ended  December  31,  2010,  2009  and  2008,  stock  option  expense  was  $4.1  million,  $3.6  million  and  $4.0, 

respectively.

At  December  31,  2010,  unamortized  compensation  expense  related  to  unvested  options,  net  of  estimated  forfeitures,  was 
approximately $8.4 million. The weighted average period over which share-based compensation expense related to these options will be

For each of the years ended December 31 of 2010, 2009 and 2008, there was approximately $8.9 million, $7.3 million and $6.1 
million of total recognized share-based compensation expense related to restricted stock arrangements granted under the plans. The total 
unrecognized  share-based  compensation  expense  as  of  December  31  2010  was  approximately  $21.3  million,  which  is  expected  to  be 
recognized over a weighted average period of approximately 3.3 years. 

On  September  22,  2009,  the  Company  entered  into  an  employment  agreement  (the  “Agreement”)  with  Dr.  Keh-Shew  Lu, 
President and Chief Executive Officer of the Company (the “Employee”), pursuant to which he will continue to be employed by the 
Company in such positions for an additional six-year term. As part of the Agreement, the Company and the Employee entered into a 
Stock Award Agreement that provides that: (i) the Company will grant to the Employee 100,000 shares of Common Stock on each of 
April  14, 2010, 2011, 2012, 2013, 2014 and 2015; (ii) each such installment would vest only if the  Company achieved a specified 
amount  of  net  sales;  (iii)  upon  the  termination  of  the  Employee’s  employment,  the  Company’s  obligation  to  grant  any  subsequent 
installment  would  terminate;  and  (iv)  any  granted  shares  would  be  automatically  forfeited  and  returned  to  the  Company  if  the 
Employee’s employment with the Company is terminated before the Company achieves the specified amount of net sales, except in 
the  case  of  death  or  disability  (as  defined)  in  which  case  the  granted  shares  would  become  fully  vested  on  the  date  of  death  or 
disability.  The estimated fair value of this grant is approximately $12 million and is being expensed on a straight line basis through

 NOTE 19 – SEGMENT INFORMATION AND ENTERPRISE-WIDE DISCLOSURES 

An operating segment is defined as a component of an enterprise about which separate financial information is available that 
is evaluated regularly by the chief decision maker, or decision-making group, in deciding how to allocate resources and in assessing 
performance.    The  Company’s  chief  decision-making  group  consists  of  the  President  and  Chief  Executive  Officer,  Chief  Financial 
Officer, Senior Vice President of Operations and Senior Vice President of Sales and Marketing.  For financial reporting purposes, the 
Company operates in a single segment, standard semiconductor products, through its various manufacturing and distribution facilities.  
The Company aggregates its products in a single segment because the products are similar and have similar economic characteristics, 
and the products are similar in production process and share the same customer type. 

The Company’s primary operations include the operations in Asia, North America and Europe.  Revenues are attributed to 

geographic areas based on the location of subsidiaries producing the revenues:

Purchase commitments – The Company has entered into non-cancelable purchase contracts for capital expenditures, primarily 

for manufacturing equipment in China, for approximately $6.5 million at December 31, 2010. 

Other commitments – During 2010, the Company announced an investment agreement with the Management Committee of 
the Chengdu Hi-Tech Industrial Development Zone (the “CDHT”).  Under this agreement, the Company has agreed to form a joint 
venture with a Chinese partner, Chengdu Ya Guang Electronic Company Limited, to establish a semiconductor manufacturing facility 
for the purpose of providing surface mounted component production, assembly and testing, and integrated circuit assembly and testing 
in  Chengdu,  People’s  Republic  of  China.    The  Company  initially  will  own  at  least  95%  of  the  joint  venture.    The  manufacturing 
facility will be developed in phases over a ten year period, and the Company is expected to contribute at least $47.5 million to the joint 
venture in installments during the first three years.  The CDHT will grant the joint venture a fifty year land lease, provide temporary 
facilities for up to three years at a subsidized rent while the joint venture builds the manufacturing facility and provide corporate and 
employee tax incentives, tax refunds, subsidies and other financial support to the joint venture and its qualified employees.  If the joint 
venture fails to achieve specified levels of investment, the investment agreement allows for a renegotiation as well as the option to 
repay  a  portion  of  such  financial  support.    This  is  a  long-term,  multi-year  project  that  will  provide  additional  capacity  once  the 
Company has reached the maximum production capacity at its Shanghai facilities in the next few years.

ADJUSTED NET INCOME

This measure consists of generally accepted accounting principles (“GAAP”) net income, which is then adjusted solely for the 
purpose of adjusting for amortization of acquisition related intangible assets, amortization of debt discount, impairment of long-
lived assets, gain on sale of assets, restructuring costs, gain on extinguishment of debt, forgiveness of debt, taxes on repatriation 
of  foreign  earnings,  inventory  valuations  and  depreciation  adjustments,  in-process  research  and  development  and  non-cash 
currency  hedge  loss.  Excluding  impairment  of  long-lived  assets,  gain  on  sale  of  assets,  restructuring  costs,  gain  on 
extinguishment  of  debt,  forgiveness  of  debt,  taxes  on  repatriation  of  foreign  earnings,  inventory  valuations  and  depreciation 
adjustments, in-process research and development and non-cash currency hedge loss provides investors with a better depiction of 
the Company’s operating results and provides a more informed baseline for modeling future earnings expectations.   Excluding 
the  amortization  of  acquisition  related  intangible  assets  and  amortization  of  debt  discount  allows  for  comparison  of  the 
Company’s  current  and  historic  operating  performance.   The  Company  excludes  the  above  listed  items  to  evaluate  the 
Company’s  operating  performance,  to  develop  budgets,  to  determine  incentive  compensation  awards  and  to  manage  cash 
expenditures.   Presentation  of  the  above  non-GAAP  measures  allows  investors  to  review  the  Company’s  results  of  operations 
from the same viewpoint as the Company’s management and Board of Directors.  The Company has historically provided similar 
non-GAAP financial measures to provide investors an enhanced understanding of its operations, facilitate investors’ analyses and 
comparisons of its current and past results of operations and provide insight into the prospects of its future performance.   The 
Company also believes the non-GAAP measures are useful to investors because they provide additional information that research 
analysts  use  to  evaluate  semiconductor  companies.   These  non-GAAP  measures  should  be  considered  in  addition  to  results 
prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results and may  differ 
from measures used by other companies.   The Company recommends a review of net income on both a GAAP basis and non-
GAAP  basis  be  performed  to  get  a  comprehensive  view  of  the  Company’s  results.  The  Company  provides  a  reconciliation  of 
GAAP net income to non-GAAP adjusted net income.

CONSOLIDATED RECONCILIATION OF NET INCOME TO ADJUSTED NET INCOME 
(in thousands, except per share data) 
(unaudited)  

ADJUSTED EARNINGS PER SHARE

This non-GAAP financial measure is the portion of the Company’s GAAP net income assigned to each share of stock, excluding 
amortization of acquisition related intangible assets, amortization of debt discount, impairment of long-lived assets, gain on sale 
of  assets,  restructuring  costs,  gain  on  extinguishment  of  debt,  forgiveness  of  debt,  taxes  on  repatriation  of  foreign  earnings, 
inventory  valuations  and  depreciation  adjustments,  in-process  research  and  development  and  non-cash  currency  hedge  loss. 
Excluding impairment of long-lived assets, gain on sale of assets, restructuring costs, gain on extinguishment of debt, forgiveness 
of  debt,  taxes  on  repatriation  of  foreign  earnings,  inventory  valuations  and  depreciation  adjustments,  in-process  research  and 
development and non-cash currency hedge loss provides investors with a better depiction of the Company’s operating results and 
provides a more informed baseline for modeling future earnings expectations, as described in further detail above. Excluding the 
amortization of acquisition related intangible assets and amortization of debt discount allows for comparison of the Company’s 
current and historic operating performance, as described in further detail above.  This non-GAAP measure should be considered 
in  addition  to  results  prepared  in  accordance  with  GAAP,  but  should  not  be  considered  a  substitute  for  or  superior  to  GAAP 
results  and  may  differ  from  measures  used  by  other  companies.   The  Company  recommends  a  review  of  diluted  earnings  per 
share  on  both  a  GAAP  basis  and  non-GAAP  basis  be  performed  to  obtain  a  comprehensive  view  of  the  Company’s  results. 
Information on how these share calculations are made is included in the reconciliation table provided.  

FREE CASH FLOW (FCF)

FCF is a non-GAAP financial measure, which is calculated by subtracting capital expenditures from cash flow from operations. 
FCF  represents  the  cash  and  cash  equivalents  that  we  are  able  to  generate  after  taking  into  account  cash  outlays  required  to 
maintain or expand property, plant and equipment. FCF is important because it allows us to pursue opportunities to develop new 
products, make acquisitions and reduce debt.  

For  detailed explanation  of the above  non-GAAP  adjustments  to reconcile  net income  to adjusted  net income,  see  “Item 2.02. 
Results of Operations and Financial Condition,” on Form 8-K filed February 15, 2010.
