GENERAL

PART I 

          We are a leading global designer, manufacturer and supplier of high-quality, application specific standard products within the 
broad discrete and analog semiconductor markets, in the consumer electronics, computing, communications, industrial and automotive 
markets. These products include diodes, rectifiers, transistors, MOSFETs, protection devices, functional specific arrays, amplifiers and 
comparators, Hall effect sensors and temperature sensors, power management devices (including LED drivers), DC-DC switching and
linear voltage regulators, voltage references, special function devices (including USB power switch, load switch, voltage supervisor 
and  motor  controllers)  and  silicon  wafers  used  to  manufacture  these  products.  These  products  are  sold  primarily  throughout  North
America, Asia 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 that provide a wider range of semiconductor products. 

          Our  product  portfolio  addresses  the  design  needs  of  many  advanced  electronic  devices,  including  high-volume  consumer 
devices such as digital audio players, 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 6,000 products, and we shipped approximately 18.1 billion units, 18.5 billion units, and 19.0 billion units in 
2007,  2008  and  2009,  respectively.  From  2004  to  2009,  our  net  sales  grew  from  $185.7 million  to  $434.4  million,  representing  a 
compound annual growth rate of 18.5%. Although 2009 was a turbulent year in which we did not sustain our historical growth rate
due  to  global  economic  factors,  for  2010,  we  expect  to  see  improvements  in  demand  across  all  platforms  and  in  particular  for  our
products utilized in panels for LCD and LED televisions as well as smartphones and set-top boxes. 

          We  serve  approximately  250  direct  customers  worldwide,  which  consist  of  original  equipment  manufacturers  (“OEM”)  and 
electronic  manufacturing  services  (“EMS”)  providers.  Additionally,  we  have  approximately  90  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 and logistics office are 
located in Dallas, Texas. A sales and marketing office is located in Westlake Village, California. Design centers are located in Dallas; 
San Jose, California; Taipei, Taiwan; Manchester, England and Neuhaus, Germany. We have two wafer fabrication facilities located
in Kansas City, Missouri and Manchester; with two manufacturing facilities located in Shanghai, China, another in Neuhaus, and a
joint venture facility located 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 2010 we expect to see improvements in demand and order rates, increased production ramps of previous design wins at new 
customers,  the  introduction  of  new  product  applications  for  existing  customers  and  improved  capacity  utilization  primarily  at  our 
wafer  fabrication  facilities.  In  addition,  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. 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 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 affects 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 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, including our cost reduction 
initiative,  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 North America, Asia and Europe. We 
aggregated our products 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 20 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  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 the first half of 2009 due to the economic downturn, 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 skilled workforce at a low overall cost base while enabling us to better serve our leading customers, many of which 
are located in Asia. During the second half of 2009, due to improvements in demand and order rates, increased production of previous 
design wins at new customers and the introduction of new products for existing customers, we saw our Shanghai facilities return to 
full capacity. 

          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, mobile handsets 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  250  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 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 continuity and experience — We believe that the continuity of our management team is a critical competitive 
strength. Three members of our executive team average over 15 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 25 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 30 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  brought  with  him  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 30 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. Carl Wertz, our former Chief Financial Officer, is 
our  Vice  President  of  Finance  and  Investor  Relations  and  has  been  employed  by  us  since  1993  and  has  over  20  years  of  financial 
experience in manufacturing and distribution industries. In 2006, we hired Edmund Tang, Vice President of Corporate Administration, 
with over 30 years of managerial and engineering experience and Francis Tang, Vice President of Discrete Product Development, was 
promoted from Global Product Manager in 2006 and came to us from FSI International Inc., a global supplier of wafer cleaning and
processing technology where he served as Asia President. 

          Management  expansion  —  In  2008,  we  strengthened  our  executive  management  team  with  the  addition  of  the  following 
management team members: Colin Greene, Europe President and Vice President of Europe Sales and Marketing, who brought with 
him over 20 years of relevant industry experience and joined us as a result of the acquisition of Zetex, at which he was COO; and Julie 
Holland, Vice President of Worldwide Analog Products, who came to us from TI with over 20 years of relevant industry experience.

OUR STRATEGY 

          Although  2009  was  a  turbulent  year  in  which  we  experienced  a  global  decrease  in  demand  for  our  products,  our  long-term
strategy has never changed. 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 products, using our packaging technology capability. 

          The principal elements of our strategy include the following: 

          Continue to rapidly introduce innovative discrete 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, mobile  handsets  and  notebooks  and  other  consumer  electronics  and  computing  devices. 
During 2009, we introduced approximately 350 new devices and achieved new design wins at over 150 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. 

          Sales of new products (products that have been sold for three years or less) for the years ended December 31, 2007, 2008 and 
2009 amounted to 35.1%, 26.9% and 14.9% of total sales, respectively, including the contribution of recent acquisitions. The sale of 
new products for 2009 was lower than those for 2008 and 2007 due primarily to a portion of our analog product revenue from Anachip 
Corp. developed in 2006 and earlier no longer being included in the overall calculation for new products for 2009 as these products 
were developed more then three years ago. We believe the sales from new products is an important measure given the short life cycles 
of some of our products and generally have gross profit margins that are higher than the margins of our standard products. 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 on 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:5)(cid:3) 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:5)(cid:3) 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 

PowerDI and SBR are registered trademarks of Diodes Incorporated

(cid:5)(cid:3) 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  as  economic  conditions  continue  to  improve.  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. We recently expanded our quality systems team 
to ensure we deliver high quality 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 the first half of 2009 due to 
the  economic  downturn,  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, 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 3 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. 

          The Notes will be convertible into cash or, at our option, cash and shares of our Common Stock based on an initial conversion 
rate,  subject  to  adjustment,  of  25.6419  shares  (split  adjusted)  per  $1,000  principal  amount  of  Notes  (which  represents  an  initial 
conversion  price  of  $39.00  per  share  (split  adjusted),  in  certain  circumstances.  In  addition,  following  a  “make-whole  fundamental
change” that occurs prior to October 1, 2011, we will, at our 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. 

          In 2008, we repurchased $46.5 million principal amount of the Notes for approximately $23.2 million in cash. During 2009, we 
repurchased $13.6 million principal amount of the Notes for approximately $10.5 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,  2009,  we  have 
repurchased a total of $94.9 million principal amount of Notes. 

          On January 1, 2009, we changed how we accounted for the Notes as a change in accounting principle. The change in accounting 
principle  required  all  adjustments  to  be  made  retrospectively  as  of  the  date  of  issuance  for  the  Notes  and  therefore,  all  periods 
presented reflect the retrospective adjustments. The 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 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. See Notes 2 and 11 of “Notes to Consolidated Financial Statements” of 
this Annual Report for additional information.

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, 
mobile handsets and notebooks.

CUSTOMERS 

          We serve approximately 250 direct customers worldwide, which consist of OEMs and EMS providers. Additionally, we have
approximately 90 distributor customers worldwide, through which we indirectly serve over 10,000 customers. Our customers include: 
(i) industry  leading  OEMs  in  a  broad  range  of  industries,  such  as  Bose  Corporation,  Honeywell  International,  Inc.,  Cisco  Systems,
Inc.,  LG  Electronics,  Inc.,  Motorola,  Inc.,  Quanta  Computer,  Inc.,  Sagem  Communication,  Delta  Electronics,  Hella,  Ltd.,  and 
Samsung Electronics Co., Ltd.; (ii) leading EMS providers, such as Celestica, Inc., Flextronics International, Ltd., Hon Hai Precision
Industry  Co.,  Ltd.,  Inventec  Corporation,  Jabil  Circuit,  Inc.,  and  Sanmina-SCI  Corporation,  who  build  end-market  products 
incorporating  our  semiconductors  for  companies  such  as  Apple  Computer,  Inc.,  Dell,  Inc.,  EMC  Corporation,  Intel  Corporation, 
Microsoft Corporation, Thompson, Inc. and Roche Diagnostics; and (iii) leading distributors such as Arrow Electronics, Inc., Avnet,
Inc., Future Electronics, Yosun Industrial Corporation, Zenitron Corporation and Rutronic. For the years of 2007, 2008 and 2009, our 
OEM and EMS customers together accounted for 61.1%, 56.6% and 52.9%, respectively, of our net sales. 

          For the years ended December 31, 2007, 2008 and 2009, Lite-On Semiconductor Corporation (LSC), which is also our largest
stockholder, (owning approximately 19.1% of our Common Stock as of December 31, 2009), and a member of the Lite-On Group of 
companies, accounted for approximately 6.2%, 3.5% and 2.1%, respectively, of our net sales. No customer accounted for 10% or more
of our net sales in 2007, 2008 and 2009. Also, 11.3%, 9.6% and 6.3% of our net sales were from the subsequent sale of products we
purchased from LSC in 2007, 2008 and 2009, respectively. See “Business — Certain relationships and related party transactions” for 
additional information. 

          We  believe  that  our  close  relationships  with  our  OEM  and  EMS  customers  have  provided  us  with  deeper  insight  into  our 
customers’ product needs than other manufacturers who we believe depend to a greater extent on indirect sales through distributors. In 
addition  to  seeking  to  expand  relationships  with  our  existing  customers,  our  strategy  is  to  pursue  new  customers  and  diversify our 
customer base by focusing on leading global consumer electronics companies and their EMS providers and distributors. 

          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, 2009, 30.4%, 28.2%,
17.3%,  11.3%  and  12.8%  of  our  net  sales  were  derived  from  China,  Taiwan,  the  U.S.,  Europe  and  all  other  markets,  respectively, 
compared  to  30.0%,  27.4%,  19.8%,  10.6%  and  12.2%  in  2008,  respectively.  We  anticipate  the  percentage  of  net  sales  shipped  to 
customers in Asia to increase as the trend towards manufacturing in Asia continues. In addition, as a result of the Zetex acquisition we 
have added significant revenue in Europe. 

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., England, 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., Europe and 
Asia.

          As  of  December 31,  2009,  our  direct  global  sales  and  marketing  organization  consisted  of  approximately  170  employees 
operating out of 18 offices. We have sales and marketing offices or representatives in Taipei, Taiwan; Shanghai and Shenzhen, China; 
Hong Kong; Beauzelle, France; and Munich, Germany; and we have 9 regional sales offices in the U.S. As of December 31, 2009, we
also had approximately 18 independent sales representative firms marketing our products. 

          Our  marketing  group  focuses  on  our  product  strategy,  product  development  road  map,  new  product  introduction  process, 
demand  assessment  and  competitive  analysis.  Our  marketing  programs  include  participation  in  industry  tradeshows,  technical 
conferences  and  technology  seminars,  sales  training  and  public  relations.  The  marketing  group  works  closely  with  our  sales  and 
research and development groups to align our product development road map. The marketing group coordinates its efforts with our
product development, operations and sales groups, as well as with our customers, sales representatives and distributors. We support 
our customers through our field application engineering and customer support organizations. 

          To  support  our  global  customer-base,  our  website  is  language-selectable  into  English,  Chinese  and  Korean,  giving  us  an
effective  marketing  tool  for  worldwide  markets.  With  its  extensive  online  product  catalog  with  advanced  search  capabilities,  our
website  facilitates  quick  and  easy  product  selection.  Our  website,  www.diodes.com,  provides  easy  access  to  our  worldwide  sales 
contacts and customer support, as well as incorporates a distributor-inventory check to provide component inventory availability and a

governance information. 

MANUFACTURING OPERATIONS AND FACILITIES 

          We operate two manufacturing facilities located in Shanghai, China, one in Neuhaus, Germany and a joint venture facility in 
Chengdu,  China,  and  our  wafer  fabrication  facilities  are  located  near  Kansas  City,  Missouri  and  near  Manchester,  England.  Our 
facilities in Shanghai and Neuhaus perform packaging, assembly and testing functions, our joint venture facility in Chengdu performs 
packaging  functions,  our  Kansas  City  facility  is  a  5-inch  and  6-inch  wafer  foundry  and  our  Manchester  facility  is  a  6-inch  wafer
foundry. 

          For  the  years  ended  at  December 31,  2008  and  2009,  we  had  invested  approximately  $30.0 million  and  $18.2 million, 
respectively, in plant and state-of-the-art equipment in China ($214.0 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,  2008  and  2009,  we  had  invested  approximately  $13.5 million  and  $25.9 million,  respectively,  in 
equipment, including expenses to shut down the 4-inch line and upgrade our 6-inch line in Manchester. 

          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 2008, we 
purchased  land  near  Dallas,  Texas  for  approximately  $4.9 million,  which  will  be  the  future  site  of  our  corporate  headquarters.  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  a 
particularly useful 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, analog and packaging technologies. 

          Our  initial  product  patent  portfolio  was  primarily  composed  of  discrete  technologies.  Then,  in  the  late  1990s,  our  engineers 
began  to  research  and  develop  packaging  technologies,  which  produced  several  important  breakthroughs  and  patents,  such  as  the 
PowerDI(cid:2)(cid:3) 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  APD  asset  acquisition  in  late  2006,  we  acquired  the  SBR®  patents  and  trademark.  SBR®  is  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. 

          In 2008, we acquired Zetex, which subsequently increased our available discrete and analog technologies with valuable 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  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,  Philips  Electronics  N.V.,  Rohm  Electronics  USA,  LLC, 
Toshiba  Corporation  and  Vishay  Intertechnology,  Inc.,  many  of  which  have  greater  financial,  marketing,  distribution  and  other 
resources than we. 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 product, 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, 2007, 2008 and 2009, Company-sponsored investment in research and development activities
was $13.0 million, $21.9 million and $23.8 million, respectively. As a percentage of net sales, research and development expense was 
3.2%,  5.1%  and  5.5%  for  2007,  2008  and  2009,  respectively.  The  increase  in  2008  was  mainly  due  to  research  and  development 
activities  associated  with  the  acquisition  of  Zetex  and  the  increase  in  2009  was  primarily  as  a  result  of  having  Zetex  research  and 
development  activities  for  the  entire  year,  offset  by  our  cost  reduction  efforts  during  2009.  For  2010,  we  anticipate  research  and
development expense to increase as net sales increase and, therefore, remain relatively flat as a percentage of net sales. 

EMPLOYEES

          As of December 31, 2009, we employed a total of 3,501 employees, of which 2,757 of our employees were in Asia, 265 were in 
the United States and 479 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 England 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, 2007, 2008 and 2009, our capital
expenditures for environmental controls have not been material. As of December 31, 2009, 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 on 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,  Lite-On  Semiconductor  Corporation  and  its  subsidiaries  and  affiliates 
(“LSC”). LSC is our largest stockholder, owning approximately 19.1% of our outstanding Common Stock as of December 31, 2009, 
and is a member of the Lite-On Group of companies. C.H. Chen, our former President and Chief Executive Officer, currently the Vice 
Chairman  of  our  Board  of  Directors,  is  also  Vice  Chairman  of  LSC.  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. L.P. Hsu, a member of
the 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 6.2%, 3.5% and 2.1% of our net sales for the years ended December 31, 2007, 2008 and 2009, 
respectively, making LSC one of our largest customers. Also for the years ended December 31, 2007, 2008 and 2009, 11.3%, 9.6% 
and 6.3%, 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  from  a  member  of  the  Lite-On  Group,  which  also  provides  us  with 
warehousing  services  at  that  location.  For  the  years  ended  December 31,  2007,  2008  and  2009,  we  paid  this  entity  in  aggregate 
amounts of $0.5 million, $0.7 million and $0.8 million, respectively, for their services. See “Risk Factors — We receive a significant 
portion of our net sales from a single customer. In addition, this customer is also our largest external supplier and is a related party. 
The loss of this customer or supplier could harm our business, results of operations and financial condition.” in Part I, Item 1A of this 
Annual Report for additional information. 

          We  sell  products  to,  and  purchase  inventory  from,  companies  owned  by  Keylink.  We  sold  products  to  companies  owned  by 
Keylink, totaling 0.6%, 0.8% and 2.6% of net sales for the years ended December 31, 2007, 2008 and 2009, respectively. Also for the 
years  ended  December 31,  2007,  2008  and  2009,  1.5%,  1.3%  and  1.2%,  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 

- 9 - 

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, 2007, 2008 and 2009 
were $9.4 million, $10.5 million and $10.7 million, respectively. 

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.

Item 1A.  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  and  operating  results  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 
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, computer, industrial, communications 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 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, Philips Electronics 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  results  of  operations  and  financial 
condition. 

We  receive  a  significant  portion  of  our  net  sales  from  a  single  customer.  In  addition,  this  customer  is  also  our  largest  external 
supplier and is a related party. The loss of this customer or supplier could harm our business, results of operations and financial 
condition. 

          In 2008 and 2009, LSC, our largest stockholder and one of our largest customers, accounted for 3.5% and 2.1%, 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 9.6% and 6.3%, respectively, of our net sales, in 2008 and 2009. The loss of LSC as either a customer or a 
supplier, or  any  significant  reductions  in  either  the  amount  of  products  it  supplies  to  us,  or  the  volume  of  orders  it  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  in  Kansas  City,  Missouri,  and  near  Manchester,  England,  while  our  facilities  in 
Shanghai, China and Neuhaus, Germany perform packaging, assembly and testing functions and our joint venture in Chengdu, China 
performs  packaging  functions.  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  decrease  in 
average selling prices (“ASP”) for our products of 6.8% in 2007, an increase of 5.6% in 2008 and a decrease of 2.1% in 2009. 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. 

- 12 - 

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

          Our  product  range  and  new  product  development  program  is  focused  on  discrete  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 could adversely affect our net sale, 
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 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:5)(cid:3) pay substantial damages for past, present and future use of the infringing technology; 

(cid:5)(cid:3) cease the manufacture, use or sale of infringing products; 

(cid:5)(cid:3) discontinue the use of infringing technology; 

(cid:5)(cid:3) expend significant resources to develop non-infringing technology; 

- 14 - 

  
     
  
     
  
     
(cid:5)(cid:3) pay substantial damages to our customers or end-users to discontinue use or replace infringing technology with non-infringing 

technology; 

(cid:5)(cid:3) license  technology  from  the  third  party  claiming  infringement,  which  license  may  not  be  available  on  commercially

reasonable terms, or at all; or 

(cid:5)(cid:3) relinquish  intellectual  property  rights  associated  with  one  or  more  of  our  patent  claims,  if  such  claims  are  held  invalid  or

otherwise unenforceable. 

          See Part I, Item 3 of this Annual Report for additional information regarding our current legal proceedings. 

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:5)(cid:3) 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:5)(cid:3) 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; 

(cid:5)(cid:3) the need for skills and techniques that are outside our traditional core expertise; 

(cid:5)(cid:3) less flexibility in shifting manufacturing or supply sources from one region to another; 

(cid:5)(cid:3) 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:5)(cid:3) difficulties developing and implementing a successful research and development team; and 

(cid:5)(cid:3) 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 fiscal year 2000, we acquired Diodes FabTech Inc., a wafer fabrication company, in order to have our 
own wafer manufacturing capabilities, (ii) in January 2006, we acquired Anachip Corp. as an entry into standard logic markets, (iii) in 
November 2006, we acquired the net operating assets of APD Semiconductor and (iv) in June 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, 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:5)(cid:3) unexpected losses of key employees or customers of the acquired company; 

(cid:5)(cid:3) bringing the acquired company’s standards, processes, procedures and controls into conformance with our operations; 

(cid:5)(cid:3) coordinating our new product and process development; 

(cid:5)(cid:3) hiring additional management and other critical personnel; 

(cid:5)(cid:3) increasing the scope, geographic diversity and complexity of our operations; 

(cid:5)(cid:3) difficulties in consolidating facilities and transferring processes and know-how; 

(cid:5)(cid:3) difficulties in reducing costs of the acquired entity’s business; 

(cid:5)(cid:3) diversion of management’s attention from the management of our business; and 

(cid:5)(cid:3) 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 on 
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 18.1 billion, 18.5 billion and 19.0 billion individual semiconductor devices in years ended at December 31, 
2007, 2008 and 2009, 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 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 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 on 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 on 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 on 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 devices are designed. 
These types of 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 products 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 necessarily 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 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, 2009, our outstanding interest-bearing debt including $135.1 million 
principal amount of senior convertible notes with a fixed rate of 2.25% and $296.6 million under our “no net cost” loan. An increase 
of  1.0%  in  interest  rates  would  increase  our  annual  interest  rate  expense  by  approximately  $0.1 million,  due  to  the  fact  that  any 
increase in interest expense related to our “no net cost” loan will be offset by interest earned on our ARS portfolio. 

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  senior  convertible  notes  in  October 2006  (“Notes”),  we  had  a  significant  amount  of  debt  and
substantial debt service requirements. As of December 31, 2009, we had outstanding debt, including $135.1 million principal amount 
of Notes with a fixed rate of 2.25% and $296.6 million under our “no net cost” loan with UBS. In addition, $58.6 million is available 
for future borrowings under our credit facilities in 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:5)(cid:3) making it more difficult for us to meet our payment and other obligations under the Notes and our other outstanding debt; 

(cid:5)(cid:3) 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:5)(cid:3) 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:5)(cid:3) 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:5)(cid:3) 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:5)(cid:3) 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.  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. 

Our Auction Rate Securities (“ARS”) are currently illiquid, and UBS AG may not honor its part of the settlement agreement with 
us to purchase our entire ARS portfolio at any time beginning from June 30, 2010 to July 2, 2012 at par value. 

          ARS are generally short-term debt instruments that are intended to provide liquidity through a Dutch auction process that resets 
the applicable interest rate at pre-determined calendar intervals. These auctions historically allowed existing investors to rollover their 
holdings and continue to own their respective securities or liquidate their holdings by selling their securities at par value. Since mid-
February 2008, there have been more sellers than buyers at each scheduled interest rate auction date and parties desiring to sell their 
securities have been unable to do so. 

          We have $296.6 million of par value ARS that became illiquid during the first quarter of 2008 due to the failure of the Dutch 
auction process. We reached a settlement with UBS AG and affiliates (“UBS AG”) in the fourth quarter of 2008, which gives us the
option to “put” the ARS portfolio back to UBS AG at any time from June 30, 2010 to July 2, 2012 at par value in exchange for cash. If 
UBS AG does not have the financial resources, or otherwise fails to repurchase our ARS portfolio, we may be required to hold the
ARS until maturity, which would negatively impact our liquidity and working capital, and may require us to reclassify and reduce the 
fair  market  value  of  our  ARS  and  our  “put”  option.  The  ARS  portfolio  includes  securities  with  maturity  dates  ranging  from  18  to
38 years. 

          As part of the settlement with UBS AG, we accepted an offer of a “no net cost” loan with one of its affiliates, UBS BANK USA 
(“UBS Bank”), which is collateralized by our ARS portfolio. The “no net cost” loan initially allowed us to borrow up to 75% of the 
market value of our ARS portfolio, as determined by UBS Bank, and is subject to collateral maintenance requirements. Under the “no
net cost” loan, the interest rate we pay on the “no net cost” loan will not exceed the interest rate earned on the pledged ARS portfolio. 
Subsequent  to  the  agreement,  we  drew  up  to  the  75%  stated  value  limit  as  determined  by  UBS  Bank.  On  November 10,  2009,  we 
received a credit line up to the full value of our ARS portfolio. Subsequently, we 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.

UBS BANK USA (“UBS Bank”) may demand full or partial repayment of our “no net cost” loan with the UBS Bank at any time at 
UBS  Bank’s  sole  option  and  without  cause,  and  UBS  Financial  Services  Inc.  may  be  unable  to  provide  us  any  alternative 
financing on substantially same terms and conditions as those of the” no net cost” loan. 

          On October 29, 2008, we entered into an ARS settlement with UBS AG and affiliates (“UBS AG”) to provide liquidity for our 
$296.6 million ARS portfolio. One of the terms of the ARS settlement is that we may accept an offer of a so-called “no net cost” loan 
from UBS Bank, an affiliate of UBS AG, initially for up to 75% of the market value, as determined by UBS Bank, of our ARS that we 
pledged  as  collateral  to  UBS  Bank.  On  November 10,  2009,  we  received  a  credit  line  up  to  the  full  value  of  our  ARS  portfolio. 
Subsequently, we 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. The “no net cost” loan is a demand loan, and UBS Bank may demand
full  or  partial  repayment  of  the  loan  at  any  time  at  UBS  Bank’s  sole  option  and  without  cause.  Although  the  ARS  settlement 
arrangement provides that UBS Financial Services Inc. would (i) support us with alternative financing on substantially same terms and 
conditions as those of the “no net cost” loan, or (ii) have one of the UBS Entities repurchase our ARS portfolio at par, it is possible 
that UBS Financial Services Inc. would be unable to provide us such alternative financing. Currently, although we do not expect that

- 19 - 

UBS Bank would demand full or partial repayment of our outstanding “no net cost” loan, we are unable to provide any assurance that
UBS Bank would not do so, and, in case such demand of repayment is made, we are also unable to provide any assurance that UBS 
Financial Services Inc. would be able to fully satisfy its obligation to provide us with alternative financing on substantially same terms 
and conditions as those of the “no net cost” loan or that a UBS Entity would repurchase our ARS portfolio at par. 

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
retirement benefit is based on the final average compensation and service of each eligible employee. In accounting for these plans, we 
are  require  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, 2009, the benefit obligation of the plan was approximately $117.5 million and total assets in such plan were 
approximately  $88.2 million.  Therefore,  the  plan  was  underfunded  by  approximately  $29.3 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. 

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. 

- 20 - 

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  2007,  2008  and  2009,  net  sales  to  customers  outside  the 
United  States  represented  79.7%,  80.2%  and  82.7%,  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:5)(cid:3) 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; 

(cid:5)(cid:3) compliance with trade or other laws in a variety of jurisdictions; 

(cid:5)(cid:3) trade restrictions, transportation delays, work stoppages, and economic and political instability; 

(cid:5)(cid:3) changes in import/export regulations, tariffs and freight rates; 

(cid:5)(cid:3) difficulties in collecting receivables and enforcing contracts; 

(cid:5)(cid:3) currency exchange rate fluctuations; 

(cid:5)(cid:3) restrictions on the transfer of funds from foreign subsidiaries to the United States; 

(cid:5)(cid:3) the possibility of international conflict, particularly between or among China, Taiwan, England and the United States; 

(cid:5)(cid:3) legal regulatory, political and cultural differences among the countries in which we do business; 

(cid:5)(cid:3) longer customer payment terms; and 

(cid:5)(cid:3) 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  2009 30.4%  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  set  up 
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,  primarily  Asian  currencies,  the  Euro  and  the
British  Pound  Sterling.  In  addition,  we  sell  our  products  in  various  currencies  and,  accordingly,  a  decline  in  the  value  of  any  such 
currency  against  the  U.S.  dollar,  which  is  our  primary  functional  currency,  could  create  a  decrease  in  our  net  sales.  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. These currencies are principally the Chinese Yuan, the Taiwanese dollar, the Japanese Yen, the Euro, the Hong Kong 
dollar and the British Pound Sterling. The Chinese government has taken action to permit the Yuan to U.S. dollar exchange rate to 
fluctuate, which may exacerbate our exposure to foreign currency risk and harm our results of operations. 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. 

- 22 - 

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 $10.6 million. 

          As  of  December 31,  2009,  accumulated  and  undistributed  earnings  of  our  subsidiaries  in  China  were  approximately 
$143 million, which we considered as a permanent investment. 

          As of December 31, 2009, we have undistributed earnings from non-U.S. operations of approximately $164 million (including 
approximately $24 million of restricted earnings, which are not available for dividends). Additional federal and state income taxes of 
approximately $39 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: 

(cid:5)(cid:3) strength of the global economy and the stability of the financial markets; 

(cid:5)(cid:3) general economic conditions in the countries where we sell our products; 

(cid:5)(cid:3) seasonality and variability in the computing and communications market and our other end-markets; 

(cid:5)(cid:3) the timing of our and our competitors’ new product introductions; 

(cid:5)(cid:3) product obsolescence; 

(cid:5)(cid:3) the scheduling, rescheduling and cancellation of large orders by our customers; 

(cid:5)(cid:3) the cyclical nature of demand for our customers’ products; 

(cid:5)(cid:3) our ability to develop new process technologies and achieve volume production at our fabrication facilities; 

(cid:5)(cid:3) changes in manufacturing yields; 

(cid:5)(cid:3) changes in gross profit margins; 

(cid:5)(cid:3) adverse movements in exchange rates, interest rates or tax rates; and 

(cid:5)(cid:3) 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:5)(cid:3) use a significant portion of our available cash; 

(cid:5)(cid:3) issue equity securities, which would dilute current stockholders’ percentage ownership; 

(cid:5)(cid:3) incur substantial debt; 

(cid:5)(cid:3) incur or assume contingent liabilities, known or unknown; 

(cid:5)(cid:3) incur amortization expenses related to intangibles; and 

(cid:5)(cid:3) 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  25.9%  of  our  outstanding  Common 
Stock, including options to purchase shares of our Common Stock that are exercisable within 60 days of December 31, 2009. 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 19.1% (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 May 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 2008 and 2009, approximately 
9.6%  and  6.3%,  respectively,  of  our  net  sales  were  from  products  manufactured  by  LSC.  In  addition  to  being  our  largest  external
supplier of finished products in each of these periods, we sold products to LSC totaling 3.5% and 2.1%, respectively, of our net sales 
during such periods, making LSC one of our largest customers. 

          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 entirely 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 receive 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 be 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.

Item 3.  Legal Proceedings

          We are currently a party to a legal proceeding described below. While we presently believe that the ultimate outcome of the 
proceeding will not have a material adverse effect on our financial position, cash flows or overall results of operations, litigation is 
subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages or an 
injunction  prohibiting  us  from  selling  one  or  more  products.  Were  an  unfavorable  ruling  to  occur,  there  exists  the  possibility  of  a 
material adverse impact on our business or results of operations for the period in which the ruling occurs or future periods. 

Integrated Discrete Devices, LLC. v. Diodes Incorporated, C.A. No. 08-888 (GMS) (D. Del.) 

          On  November 25,  2008,  Integrated  Discrete  Devices,  LLC  (“IDD”)  filed  a  complaint  for  patent  infringement  against  the 
Company in the United States District Court for the District of Delaware (the “Court”) under the patent laws of the United States, 35 
U.S.C. §§ 100 et seq., alleging that the Company has been and is infringing, actively inducing others to infringe, or contributing to the 
infringement of IDD’s United States Patent No. 5,825,079 (the “‘079 patent”) by making, using, selling, offering to sell, or importing 
diode products embodying the patented invention, including, but not limited to, its Super Barrier Rectifier (or SBR®) diodes. IDD’s 
complaint  further  alleges  that  the  Company  has  been  and  is  infringing  the  ‘079  patent  with  knowledge  of  the  patent,  and  thus  the
Company’s infringement is willful and that the Company will continue to infringe the ‘079 patent unless and until it is enjoined by the 
Court. IDD’s complaint further alleges that the Company has caused and will continue to cause IDD irreparable injury and damage by 
infringing the ‘079 patent and that IDD will suffer further irreparable injury unless and until the Company is enjoined from infringing 
the ‘079 patent. IDD’s complaint seeks that the Court enter judgment that the Company infringes the ‘079 patent and enter an order
permanently enjoining the Company from infringing the ‘079 patent. IDD also seeks unspecified damages together with pre-judgment
and post-judgment interest and costs, treble damages, additional damage, an injunction, attorneys’ fees, expenses and costs as well as 
other relief. 

          On  January 23,  2009,  the  Company  filed  an  answer  and  counterclaims  to  IDD’s  complaint.  Fact  discovery  is  currently 
scheduled  to  close  on  March 26,  2010.  A  claim  construction  hearing  is  currently  scheduled  for  April 28,  2010.  Trial  is  presently
scheduled to begin on March 14, 2011. 

          The Company believes that it has meritorious defenses against IDD’s claims, and intends to defend the lawsuit vigorously.

          From  time  to  time,  the  Company  is  involved  in  various  routine  legal  proceedings  incidental  to  the  conduct  of  its  business. 
Management  does  not  believe  that  any  of  these  legal  proceedings  will  have  a  material  adverse  impact  on  the  business,  financial 
condition or results of operations of the Company. 

Item 4.  Submission of Matters to a Vote of Security Holders

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.

          We may from time to time seek to repurchase our outstanding Notes 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. 

          The following table provides information regarding the repurchases of our Notes during the fourth quarter of 2009:

Highlights for the Year Ended December 31, 2009 

(cid:5)(cid:3) Net  sales  for  2009  increased  to  $434.4 million,  an  increase  from  $432.8 million  in  2008,  which  included  seven  months  of

Zetex revenues; 

(cid:5)(cid:3) Gross profit for 2009 was $121.2 million, or 27.9% of net sales; 

(cid:5)(cid:3) Net income attributable to common stockholders was $7.5 million. 

(cid:5)(cid:3) On November 10, 2009, the credit line on our “no net cost” loan from UBS BANK USA (“UBS Bank”) was increased to the

full value of our ARS portfolio; and 

(cid:5)(cid:3) During 2009, we repurchased $13.6 million principal amount of our 2.25% Convertible Senior Notes due 2026 (“Notes”) for
approximately  $10.5 million  in  cash  and  $34.8 million  principal  amount  of  our  Notes  for  approximately  $31.4 million  in 
shares of Common Stock. 

Business Outlook 

          For  2010  we  expect  to  see  improvements  in  demand  and  order  rates,  increased  production  of  previous  design  wins  at  new
customers,  the  introduction  of  new  product  applications  for  existing  customers  and  improved  capacity  utilization  primarily  at  our 
wafer  fabrication  facilities.  In  addition,  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. 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 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 term 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 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, including our 
cost reduction initiative, 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 

          At  the  end  of  2008  and  in  the  beginning  of  2009,  we  saw  a  slowdown  in  global  economic  activity  and  a  decrease  in  global
demand for our products and, therefore, implemented cost reduction initiatives and focused on cash flows from operations. During the 
first quarter of 2009, we strengthened our inventory position, completed the cost reduction initiatives and continued to focus on cash 
flows from operations. During the second and third quarters of 2009, as we continued to focus on cash flows, we saw continued

improvements  in  demand  and  order  rates,  increased  production  of  previous  design  wins  at  new  customers,  introduced  new  product 
applications  for  existing  customers  and  improved  capacity  utilization  primarily  at  our  packaging  facilities,  which  were  near  full
utilization  by  the  end  of  the  third  quarter.  During  the  fourth  quarter  of  2009,  our  business  continued  to  benefit  from  the  continued
strength in China, combined with general improvements in North America and Europe and improved capacity utilization at our wafer
fabrication facilities. While cash preservation was the focus during most of 2009, in the fourth quarter of 2009, we resumed certain
expenditures, such as authorizations for capital expenditures, to their normal range of 10% to 12% of net sales. 

          Although 2009 was a turbulent year due to global economic factors, our long-term strategy has never changed and for 2010, 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 products, using our packaging technology capability.

          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:5)(cid:3) Continue to rapidly introduce innovative discrete and analog semiconductor products; 

(cid:5)(cid:3) Expand our available market opportunities; 

(cid:5)(cid:3) Maintain intense customer focus; 

(cid:5)(cid:3) Enhance cost competitiveness; and 

(cid:5)(cid:3) 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:5)(cid:3) Although we have seen increased demand for our products during 2009, the recent economic downturn has affected our 2009
results in which we did not sustain our historical growth rate. For 2010, we anticipate continued improvement in demand and
order rates and improvements in capacity utilization at our wafer fabrication facilities. 

(cid:5)(cid:3) For  the  years  ended  December 31,  2007,  2008  and  2009,  our  original  equipment  manufactures  (“OEM”)  and  electronic
manufacturing services (“EMS”) customers together accounted for 61.1%, 56.6% and 52.9% of total sales, respectively, while
our global network of distributors accounted for 38.9%, 43.4% and 47.1% of total sales, respectively. 

(cid:5)(cid:3) We have experienced substantial pressure from our customers and competitors to reduce the selling price 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. As we look forward to 2010, we expect any future improvements in net income to result primarily
from increases in sales volume and improvements in product mix. 

(cid:5)(cid:3) Sales of new products (products that have been sold for three years or less) for the years ended December 31, 2007, 2008 and
2009 amounted to 35.1%, 26.9% and 14.9% of total sales, respectively, including the contribution of recent acquisitions. The
sale  of  new  products  for  2009  were  lower  than  those  for  2008  and  2007  due  primarily  to  a  portion  of  our  analog  product
revenue  from  Anachip  Corp.  developed  in  2006  and  earlier  no  longer  being  included  in  the  overall  calculation  for  new
products for 2009 as these products were developed more then three years ago. Although sales of new products were lower in
2009 compared to 2008, we have seen recent improvements, primarily in the LED drivers, Hall effect sensors, SBR ® devices 
and  bi-polar  products.  New  products  generally  have  gross  profit  margins  that  are  higher  than  the  margins  of  our  standard
products. We believe sales from new products are an important measure given the short life cycles of some of our products.
Our net sales of new products as a percentage of our net sales will depend on the demand for our standard products, as well as
our product mix. 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  on  our business,  results  of  operations  and  financial  condition.”  in  Part I, 
Item 1A of this Annual Report for additional information. 

(cid:5)(cid:3) Our gross profit margin was 27.9% in 2009, compared to 30.6% in 2008 and 32.5% in 2007. Our gross profit margin decrease 
in  2009  was  affected  by  lower  capacity  utilization  at  our  manufacturing  operations  primarily  due  to  the  recent  economic
downturn and the decrease in demand for our products. Future gross profit margins will depend primarily on our utilization,
product mix, cost savings, and the demand for our products. During the first quarter of 2009, the capacity utilization at our
packaging facilities decreased to approximately 50%, but has since improved to full capacity utilization by the end of 2009. In
addition,  during  the  third  and  fourth  quarter  of  2009,  we  have  seen  improvements  in  our  capacity  utilization  at  our  wafer
fabrication facilities and expect further improvements in utilization going into 2010.

(cid:5)(cid:3) For 2009, the percentage of our net  sales derived from our Asian subsidiaries was 76.8%, compared to 74.2% in 2008 and
75.4% in 2007. We expect our net sales to the Asian market to increase as a percentage of our total net sales as a result of our
customers’ continuing to shift their manufacturing of electronic products to Asia. 

(cid:5)(cid:3) As  a  result  of  the  Zetex  acquisition  we  have  added  significant  revenue  in  Europe.  As  such,  Europe  accounted  for

approximately 10.0% and 10.4% of our revenues in 2008 and 2009, respectively. 

(cid:5)(cid:3) As  of  December 31,  2009,  we  had  invested  approximately  $214.0 million  in  our  manufacturing  facilities  in  China.  During 
2009, we invested approximately $18.2 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:5)(cid:3) For 2009, our capital expenditures were approximately 6% of our net sales, which is a reduction from our historical 10% to
12% model but in line with our cost reduction initiatives implemented in the first quarter of 2009. While cash preservation
was our focus during most of 2009, for 2010, we intend to resume capital expenditures to their normal range of 10% to 12%
of net sales. 

(cid:5)(cid:3) We increased our investment in research and development from $21.9 million in 2008 to $23.8 million in 2009, primarily as a 
result of the Zetex acquisition. In 2009, research and development expenses were approximately 5.5% of net sales. For 2010,
we expect research and development to increase in absolute dollars as we anticipate continued improvement in demand but 
remain comparable as a percentage of net sales. 

Convertible Senior Notes 

          On October 12, 2006, we issued and sold Notes with an aggregate principal amount of $230 million due 2026, 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. The Notes will be convertible into cash or, at our option, cash and shares of our Common Stock based on 
an  initial  conversion  rate,  subject  to  adjustment,  of  25.6419  shares  (split  adjusted)  per  $1,000  principal  amount  of  Notes  (which 
represents  an  initial  conversion price of $39.00 per share,  split adjusted),  in  certain  circumstances.  In  addition, following  a  “make-
whole fundamental change” that occurs prior to October 1, 2011, we will, at our 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. 

          In 2008, we repurchased $46.5 million principal amount of the Notes for approximately $23.2 million in cash. During 2009, we 
repurchased $13.6 million principal amount of the Notes for approximately $10.5 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,  2009,  we  have 
repurchased a total of $94.9 million principal amount of Notes. 

          On January 1, 2009, we changed how we accounted for our Notes as a change in accounting principle. The change in accounting 
principle  required  all  adjustments  to  be  made  retrospectively  as  of  the  date  of  issuance  for  the  Notes  and  therefore,  all  periods 
presented reflect the retrospective adjustments. The 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 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. See Notes 2 and 11 of “Notes to Consolidated Financial Statements” of 
this Annual Report for additional information. 

Recent Acquisitions 

          On June 9, 2008, we completed the acquisition of all the outstanding ordinary capital stock of Zetex, a company incorporated
under the laws of England and Wales. The Zetex shareholders received 85.45 pence in cash per Zetex ordinary share, valuing the fully 
diluted  share  capital  of  Zetex  at  approximately  U.S.$176.3 million  (based  on  a  USD:GBP  exchange  rate  of  1.9778),  excluding 
acquisition costs, fees and expenses. In addition, in order to finance the acquisition, we entered into a loan agreement for $165 million 
that was later replaced with a “no net cost” loan. See “Debt instruments” below for additional information about the “no net cost” 
loan.  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  and  is  supported  by  a  global  network  of  distributors  and  manufacturer’s  representatives.  See  Note  3  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.

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:5)(cid:3) The condition of the economy in general and of the semiconductor industry in particular, 

(cid:5)(cid:3) Our customers’ adjustments in their order levels, 

(cid:5)(cid:3) Changes in our pricing policies or the pricing policies of our competitors or suppliers, 

(cid:5)(cid:3) The addition or termination of key supplier relationships, 

(cid:5)(cid:3) The rate of introduction and acceptance by our customers of new products, 

(cid:5)(cid:3) Our ability to compete effectively with our current and future competitors, 

(cid:5)(cid:3) Our  ability  to  enter  into  and  renew  key  corporate  and  strategic  relationships  with  our  customers,  vendors  and  strategic 

alliances, 

(cid:5)(cid:3) Changes in foreign currency exchange rates, 

(cid:5)(cid:3) A major disruption of our information technology infrastructure, and 

(cid:5)(cid:3) Unforeseen catastrophic events, such as armed conflict, terrorism, fires, typhoons and earthquakes. 

          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, England 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  consist  of  amortization  of  acquisition-related  intangible  assets,  such  as 
developed technologies and customer relationships. 

          In-process research and development 

          In-process research and development (“IPR&D”) expenses consist of immediately expensed IPR&D related to acquisitions prior 
to 2009, which had not yet reached technological feasibility and had no alternative future use as of the acquisition date in accordance 
with FASB Statement of Financial Accounting Standards (“SFAS”) No. 141, Business Combinations.

          Restructuring charge 

          Restructuring  charge  consists  of  charges  to  reduce  our  cost  structure  to  enhance  operating  effectiveness  and  improve 
profitability.

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. In general, earnings in the U.S. are currently 
subject to tax rates of 35%. In Taiwan, earnings are subject to 25% income tax rate in 2009 and 20% in 2010. 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). 
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. 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 our China subsidiaries and sold to customers outside of Taiwan and Hong Kong, respectively. 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, we receive credit against our U.S. tax liability for income taxes paid by our foreign subsidiaries.

          In  addition,  the  earnings  of  Shanghai  Kai  Hong  Technology  Co.,  Ltd.,  which  is  located  in  the  Songjiang  Export  Zone  of
Shanghai,  China, were  subject  to  a  12.5% tax  rate  in  2009. Due  to  its qualification  as a  high  technology  company, the  earnings  of 
Shanghai Kai Hong Electronic Co., Ltd. were subject to 15% tax rate in 2009. 

          On June 9, 2008, the Company completed the acquisition of all the outstanding ordinary capital stock of Zetex. Earnings in the 
United Kingdom are currently subject to a tax rate of 28% and its earnings in Hong Kong are subject to a 16.5% tax rate. In addition, 
earnings in Germany are subject to a 30% tax rate.

Net sales 

2008    
$  432,785    

2009
$ 434,357

          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 recent 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 recent economic downturn.

          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 recent 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 recent economic downturn. 

Selling, general and administrative (“SG&A”)

          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.

2008    
$  21,882    

2009
$ 23,757

          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 

2008    
$  3,706    

2009
$ 4,665

          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”) 

2008     
$  7,865    

$

2009
—

          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 

2008    
$  11,991    

2009
$ 4,871

          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 continued interruption in the
ARS auction markets. 

Interest expense 

2008    
$  9,044    

2009
$ 7,471 

          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 

2008    
$  10,690    

2009
$ 8,302

          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) 

2008    
$  9,501

(777)

$

          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 

2008    
$  (2,158)   

2009
$ 1,302

          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 last year was impacted by the non-cash income tax expense of 
approximately  $10.6 million  associated  with  repatriating  earnings  of  foreign  subsidiaries  to  the  U.S.  This  was  partially  offset  by 
provision-to-return adjustments recorded in 2009. For 2010, we anticipate our full-year effective tax rate to be in the mid-teen range as 
we continue to take advantage of available strategies to optimize our tax rate across the jurisdictions in which we operate. 

Noncontrolling interest 

2008    
$  2,290    

2009
$ 2,335

          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 

2008    
$  28,239    

2009
$ 7,513

          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.

Net sales 

2007    
$  401,159    

2008
$ 432,785

          Net  sales  for  2008  increased  $31.6 million  to  $432.8 million  from  $401.2 million  for  2007.  The  7.9%  increase  was  due 
primarily to a 2.2% increase in units sold and a 5.6% increase in ASP. The revenue increase was attributable to sales increases in all 
industry segments mainly due to the Zetex acquisition, partially offset by an overall weakening of global demand due to the global 
economic  downturn,  as  well  as  our  foundry  and  subcontracting  businesses,  which  showed  greater  weakness  than  our  core  revenue 
drivers. Significant price pressure and an unfavorable commodity-based product mix also negatively affected sales in 2008.

          Cost of goods sold increased $29.5 million, or 10.9%, for 2008 compared to $270.8 million for 2007. As a percent of sales, cost 
of goods sold increased from 67.5% for 2007 to 69.4% for 2008. Our AUP increased approximately 8.5% from 2007. The increase in 
cost of  goods sold  and  the percentage of  sales  increase were  negatively  affected by  the one  time  non-cash  expense  of $5.4  million 
incurred during the third quarter of 2008 for the increase of inventory for reasonable profit allowance and depreciation expense related 
to  fixed  assets  in  connection  with  the  Zetex  acquisition  along  with  lower  capacity  utilization  in  our  manufacturing  operations  due 
primarily to market conditions. 

          Gross profit for 2008 increased 14.5% to $132.5 million from $130.5 million for 2007. Gross profit margin as a percentage of 
net  sales  was  30.6%  for  2008,  compared  to  32.5%  for  2007.  The  decreased  gross  margin  was  primarily  due  to  the  increase  of 
inventory for reasonable profit allowance and depreciation expense of fixed assets in connection with the Zetex acquisition and lower 
capacity utilization in our manufacturing operations.

additional  SG&A  expenses  related  to  the  Zetex  operations.  The  following  expense  categories  increased,  mainly  due  to  additional 
Zetex SG&A expenses: (i) $5.0 million increase in wages and related benefits, including share-based compensation, (ii) $3.6 million 
increase  in  facility  expense,  depreciation,  supplies  and  other  operating  expenses,  (iii)  $3.6  million  increase  in  communication,
professional expense and travel expense, and (iv) $1.3 million increase in marketing and selling expense. SG&A, as a percentage of 
net sales, was 15.8% in 2008, compared to 13.7% in 2007.

The  increase  was  due  primarily  to  additional  R&D  expenses  related  to  the  Zetex  operations.  The  following  expense  categories 
increased, mainly due to additional Zetex R&D expenses: (i) $5.3 million increase in wages and related benefits and (ii) $3.7 million 
increase in operating expenses, depreciation, building maintenance and operating expense. 

Amortization of acquisition-related intangible assets

          Amortization of acquisition-related intangibles for 2008 increased $2.9 million to $3.7 million from $0.8 million for 2007. The 
increase  was  due  primarily  to  approximately  $2.6 million  of  non-cash  amortization  expense  associated  with  the  preliminary 
identification of intangible assets in connection with the acquisition of Zetex. The 2008 charge related to seven months of amortization 
expense.

          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. 

Restructuring charge 

2007

2008
$ 4,089

          In  the  years  ended  December 31,  2007  and  2008,  we  recorded  approximately  $1.1 million  and  $4.1 million  in  restructuring 
charges, respectively. We have recorded various restructuring charges to reduce our cost structure to enhance operating effectiveness 
and  improve  future  profitability.  These  restructuring  activities  impacted  several  functional  areas  of  our  operations  in  different 
locations  and  were  undertaken  to  meet  specific  business  objectives  in  light  of  the  facts  and  circumstances  at  the  time  of  each 
restructuring  event.  For  2008,  these  charges  included  costs  to  reduce  the  headcount  in  our  U.K.  operations  along  with  additional
headcount reductions  in our worldwide workforce. For 2007,  these  charges  include  costs  related  to the  consolidation  of our  analog 
wafer  probe  and  final  test  operations  from  Hsinchu,  Taiwan  to  our  manufacturing  facilities  in  Shanghai,  China,  which  primarily 
consisted of termination and severance costs, and impairment of fixed assets. 

Interest income 

2007    
$  18,117    

2008
$ 11,991

          Interest income for 2008 decreased to $12.0 million, compared to $18.1 million for 2007, due primarily to a decrease in interest 
income earned on our long-term investment securities. Interest income for 2008 was impacted by the interruption in the ARS auction 
markets. 

Interest expense 

2007    
$  6,511    

2008
$ 9,044

          Interest expense for 2008 was $9.0 million, compared to $6.5 million for 2007. The $2.5 million increase is due primarily  to 
interest expense related to the $165 million loan used to finance the June 2008 Zetex acquisition. Interest expense related to the 2.25% 
stated rate on the Notes was approximately $5.2 million in both 2008 and 2007.

2007    
$  9,996    

2008
$ 10,690

          Amortization of debt discount for 2008 was $10.7 million, compared to $10.0 million for 2007. Amortization of debt discount 
consists of amortization expense related to our Notes. 

Other income (expense)

$ 

2008
$ 9,501

          Other income for 2008 was $9.5 million, compared to other expense of $0.2 million for 2007. The $9.7 million increase 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) and $0.9 million foreign currency transaction gains due primarily to favorable Taiwan currency 
and  China  currency  exchange  rate  changes  during  the  year,  offset  by  approximately  $1.5  million  of  loss  from  forward  contract 
hedging related to hedging the Zetex acquisition purchase price, and $5.4 million foreign currency transaction losses due primarily to 
strengthening of the U.S. dollar versus the British Pound negatively affecting foreign currency hedges entered into by Zetex prior to 
our acquisition. 

Income tax provision 

2007     
$  5,655    

2008
$ (2,158)

          We recognized income tax benefit of $2.2 million for 2008, resulting in an effective tax rate of (7.6)%, as compared to 9.2% for 
2007.  Our  lower  effective  tax  rate  compared  with  the  same  period  last  year  was  the  result  of  income  tax  refunds  in  China  and  the
favorable  settlement  of  income  tax  audits  in  Taiwan,  partially  offset  by  the  purchase  accounting  adjustments  from  the  Zetex 
acquisition and the repatriation of earnings from our Hong Kong subsidiary. 

Noncontrolling interest 

2007    
$  2,376    

2008
$ 2,290

          Noncontrolling interest primarily represents the minority investor’s share of the earnings of our China and Taiwan subsidiaries 
for the year. 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. As of 
December 31, 2007 and 2008, we had 95% controlling interests in Shanghai Kai Hong Electronic Co., Ltd. and Shanghai Kai Hong 
Technology Co., Ltd., and a 99.8% controlling interest in Anachip Corp. 

Net income attributable to common stockholders 

2007    
$  53,754    

2008

          Net income attributable to common stockholders decreased 47.5% to $28.2 million (or $0.69 basic earnings per share and $0.66 
diluted  earnings  per  share)  for  2008,  compared  to  $53.8 million  (or  $1.36  basic  earnings  per  share  and  $1.27  diluted  earnings  per
share)  for  2007,  due  primarily  to  increasing  pressure  on  ASP  and  lower  gross  profit  margin,  the  deteriorating  global  economy  and
approximately $14.7 million in purchase price adjustments related to the Zetex acquisition.

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. 
We currently 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  with  borrowing  capacities  of  approximately  $46 million  of  which 
approximately $2.8 million has been borrowed and $4.8 million has been used for import and export guarantee. Our primary liquidity 
requirements  have  been  to  meet  our  inventory  and  capital  expenditure  needs.  For  2007,  2008  and  2009,  our  working  capital  was 
$451.8 million, $209.6 million, and $354.3 million, respectively. Our working capital increased in 2009 mainly due to our increased 
cash position. 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. Cash and cash equivalents, the conversion of other working-capital items and borrowings are expected to be sufficient to 
fund on-going operations. 

          In  October 2006,  we  issued  and  sold  Notes  with  an  aggregate  principal  amount  of  $230 million  due  2026,  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. In connection with the issuance of the Notes, we 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 repayment of debt, the related unamortized debt issuance costs are charged to expense. The 
remaining  $1.6 million  was  recorded  as  part  of  additional  paid-in  capital  and  is  not  being  amortized.  In  2008,  we  repurchased 
$46.5 million  principal  amount  of  the  Notes  for  approximately  $23.2 million  in  cash.  During  2009,  we  repurchased  $13.6 million 
principal amount of the Notes for approximately $10.5 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, 2009, we have repurchased a total of $94.9 million
principal amount of Notes. 

          On January 1, 2009, we changed how we accounted for our Notes as a change in accounting principle. The change in accounting 
principle  required  all  adjustments  to  be  made  retrospectively  as  of  the  date  of  issuance  for  the  Notes  and,  therefore,  all  periods 
presented reflect the retrospective adjustments. See Notes 2 and 11 of “Notes to Consolidated Financial Statements” of this Annual 
Report for additional information. 

          In 2007, 2008 and 2009, our capital expenditures were $54.2 million, $53.4 million and $25.9 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 an office building in Taiwan. Capital expenditures for 2009 were approximately 6% of our 
net sales, which is a reduction from our historical 10% to 12% model but in line with our cost reduction initiatives implemented in the 
first quarter of 2009. While cash preservation was our focus during most of 2009, for 2010, we intend to resume capital expenditures
to their normal range of 10% to 12% of net sales. 

          As of December 31, 2009, we had $296.6 million invested in ARS, which are classified as short-term, trading securities. While 
we continue to earn and receive interest on these investments at the maximum contractual rate, the estimated fair values of these ARS 
no longer approximates par value. On October 29, 2008, we reached a settlement with UBS AG and affiliates (“UBS AG”), in regard
to our ARS portfolio, which gives us the option to “put” the $296.6 million ARS portfolio back to UBS AG at any time from June 30, 
2010 through July 2, 2012 at par value in exchange for cash. See Notes 5 and 6 of “Notes to Consolidated Financial Statements” and
“Risk Factors — Our Auction Rate Securities (“ARS”) are currently illiquid, and UBS AG may not honor its part of the settlement 
agreement with us to purchase our entire ARS portfolio at any time beginning from June 30, 2010 to July 2, 2012 at par value” in 
Part I, Item 1A of this Annual Report for additional information. 

          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 is collateralized by our ARS portfolio. The “no net cost” loan initially allowed us
to draw up to 75% of the market value of our ARS portfolio, as determined by the UBS Bank, and is subject to collateral maintenance 
requirements. Under the “no net cost” loan, the interest rate we pay on the “no net cost” loan will not exceed the interest rate earned 
on the pledged ARS portfolio. Subsequent to the agreement, we drew up to the 75% market value limit as determined by UBS Bank. 
On November 10, 2009, we received a credit line of up to the full par value of our ARS portfolio. Subsequently, we 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.  See  Note  11  of  “Notes  to  Consolidated  Financial  Statements”  of  this  Annual  Report  for  additional
information. 
          Since the failure of the auctions for the ARS market, through December 31, 2009, the underlying institutions have repurchased 
approximately $24.0 million of the Company’s ARS at par value, the proceeds of which have been applied against the “no net cost” 
loan. During January 2010, an additional $55.3 million ARS were repurchased at par by the issuers, bringing the total ARS par value 
and balance of the “no net cost” loan to $241.3 million as of January 31, 2010.

          Discussion of Cash Flows 

          Cash and cash equivalents have increased from $56.2 million at December 31, 2007, to $103.5 million at December 31, 2008, 
then increased to $242.0 million at December 31, 2009. The increase from 2007 to 2008 was primarily due to net cash provided by
operating activities. The increase during 2009 was mainly due to net cash provided by operating activities and drawing up to the full 
value of the “no net cost” loan.

          Operating Activities 

          Net cash provided by operating activities during 2009 was $65.5 million, resulting primarily from $9.9 million of net income in 
the period, $42.5 million of depreciation and amortization, $14.4 million increase in accounts payable, $10.9 million from non-cash 
share-based  compensation  and  $8.3 million  from  amortization  of  discount  on  Notes,  partially  offset  by  a  $26.8 million  increase  in 
accounts receivables. Net cash provided by operating activities was $57.2 million for 2008 and $90.8 million for 2007. 

          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). We continue to closely monitor our credit
terms with our customers, while at times providing extended terms. 

          Net cash provided by operating activities decreased by $33.6 million from 2007 to 2008. This decrease resulted primarily from a 
$20.7 million  decrease  in  net  income  (from  $59.7 million  in  2007  to  $39.0 million  in  2008)  and  a  $15.7 million  decrease  in  net 
working capital, partially offset by a $22.4 million increase in depreciation and amortization expense. 

          Investing Activities 

          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. 

          Net cash used by investing activities for 2007 was $88.4 million, resulting primarily from $56.1 million in capital expenditures 
and $32.5 million in purchase of securities. 

          Financing Activities 

          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. 

Net cash provided by financing activities for 2007 was $4.7 million, resulting primarily from $7.6 million from stock option 

exercises in 2007 and repayments of long-term debt, partially offset by $2.8 million in repayments of long-term debt.

          Debt instruments 

          On November 25, 2009 we entered into a credit agreement (“the Credit Agreement”) with Bank of America, N.A. (“Bank of
America”). 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 24, 2010 (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,  2009,  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 thereof 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 thereof 
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 thereof 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 
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 made to us 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,  the 
following: (a) we 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;  (b) we  and  our  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) we and our subsidiaries shall not make any Investments 
except  as  specified  in  the  Credit  Agreement;  (d) we  and  our  subsidiaries  shall  not  create,  incur,  assume  or  suffer  to  exist  any
Indebtedness except as specified in the Credit Agreement; (e) we and our subsidiaries shall not dissolve or merge or consolidate with 
or into another entity except as specified in the Credit Agreement; (f) we and our subsidiaries shall not make any Disposition except as 
specified  in  the  Credit  Agreement;  (g) we  and  our  subsidiaries  shall  not  make  any  Restricted  Payment,  or  issue  or  sell  any  Equity 
Interests, except as specified in the Credit Agreement; (h) we and our subsidiaries shall not engage in any material line of business 
substantially different from those lines of business that are currently conducted by us and our subsidiaries; (i) we and our subsidiaries 
shall not enter into any transaction of any kind with any Affiliate of ours except as specified in the Credit Agreement; (j) we and our 
subsidiaries shall not enter into certain burdensome Contractual Obligations except as specified in the Credit Agreement; and (k) we 
and our 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, 2009, we were in compliance with the bank covenants. 

On  November 4,  2008,  we  accepted  an  offer  of  a  “no  net  cost”  loan  with  UBS  Bank,  which  is  collateralized  by  our  ARS 
portfolio. The “no net cost” loan initially allowed us to draw up to 75% of the market value of our ARS portfolio, as determined by the 
UBS Bank. Under the “no net cost” loan, the interest rate we pay on the “no net cost” loan will not exceed the interest rate earned on 
the pledged ARS portfolio. Subsequent to the agreement, we drew up to the 75% market value limit as determined by UBS Bank. On 
November 10, 2009, we received a credit line of up to the full par value of our ARS portfolio. Subsequently, we 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. See Note 11 of “Notes to Consolidated Financial Statements” and “Risk Factors — Restrictions in our 
credit  facilities  may  limit  our  business  and  financial  activities,  including  our  ability  to  obtain  additional  capital  in  the  future.”  in 
Part 1, Item 1A of this Annual Report for additional information. 

- 46 - 

As  of  December 31,  2009,  our  Asia  and  Europe  subsidiaries  have  available  lines  of  credit  of  up  to  an  aggregate  of 
approximately  $46 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, 2009, $2.8 million was 
outstanding on these lines of credit, and the interest rates ranged from 1.4% to 1.9%. 

          In October, 2006, we issued and sold Notes with an aggregate principal amount of $230 million due 2026, 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. 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,  we  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, we treat, and each holder of 
the Notes agreed under the indenture to treat, the Notes as contingent payment debt instruments governed by special tax rules and to 
be bound by our application of those rules to the Notes. 

          In 2008, we repurchased $46.5 million principal amount of the Notes for approximately $23.2 million in cash. During 2009, we 
repurchased $13.6 million principal amount of the Notes for approximately $10.5 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,  2009,  we  have 
repurchased a total of $94.9 million principal amount of Notes. On January 1, 2009, we changed how we accounted for our Notes as a 
change  in  accounting  principle.  See  Notes  2  and  11  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.

(1)    On each of October 1, 2011, October 1, 2016 and October 1, 2021, holders of our Notes 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. 

Note: The table does not include the “no net cost” loan from UBS Bank as it is currently classified as short-term debt. 

          Tax liabilities are not included in the above contractual obligations as we cannot make reasonable estimates of the amount and 
period in which those tax liabilities would be paid. See  “Accounting for income taxes” below and Note 16 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,  the
Company recognizes revenue for sales to distributors using the “sell in” model, which is when product is sold to the distributor. 

          Certain distributors and other customers have limited rights of return and/or are entitled to price adjustments on inventory held 
in the distributors’ stock or upon sale to end customers. The Company reduces revenue in the period of sale for estimates of product 
returns,  distributor  price  adjustments  and  other  allowances,  the  majority  of  which  are  related  to  our  U.S.  operations.  Our  reserve 
estimates are based upon historical data as well as projections of revenues, 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 revenues. 

          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, both finished goods and raw materials, 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. 

          Allowance for doubtful accounts 

          We evaluate the collectability of our accounts receivable based upon a combination of factors, including the current business 
environment and historical experience. If we are aware of a customer’s inability to meet its financial obligations to us, we record an 
allowance to reduce the receivable to the amount we reasonably believe we will be able to collect from the customer. For all other 
customers,  we  record  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. 

          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, 
2009. 

          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 
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 

          We use the methods of fair value to value our ARS portfolio. 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 following: 

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. 

          Due  to  lack  of  observable  market  quotes  on  our  ARS  portfolio  and  “put”  option,  we  utilized  a  valuation  model  that  relies
exclusively  on  Level  3  inputs  including  those  that  are  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 
our  ARS  investment  portfolio  is  subject  to  uncertainties  that  are  difficult  to  predict.  Factors  that  may  impact  our  valuation  include 
changes  to  credit  rating  of  the  securities  as  well  as  to  the  underlying  assets  supporting  those  securities,  rates  of  default  of  the 
underlying assets, underlying collateral value, discount rates, counterparty risk and ongoing strength and quality of market credit and 
liquidity. 

          In  addition,  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 

          On January 1, 2009, we changed how we accounted for our Notes as a change in accounting principle. The change in accounting 
principle  required  all  adjustments  to  be  made  retrospectively  as  of  the  date  of  issuance  for  the  Notes  and,  therefore,  all  periods 
presented reflect the retrospective adjustments. 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.

Recently Issued Accounting Pronouncements 

          See  Note  1  of  “Notes  to  Consolidated  Financial  Statements”  of  this  Annual  Report  for  additional  information  regarding  the 
status of recently issued accounting pronouncements. 

Item 7A.  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. 

          If  the  Chinese  Yuan,  the  Taiwanese  dollar,  the  Euro  and  the  British  Pound  Sterling  were  to  strengthen  or  weaken  by  1.0%
against  the U.S.  dollar, we  would  experience  currency  gain  or  loss  of approximately  $0.3 million.  In  the  future, we  may  enter  into 
hedging arrangements designed to mitigate foreign currency fluctuations. The Chinese government permits the Chinese Yuan to float
more freely compared to other world currencies. Should the Chinese government allow a significant Chinese Yuan appreciation, and
we do not take appropriate means to offset this exposure, the effect could have a material adverse impact upon our financial results. 

          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. As of December 31, 2009, the plan is underfunded and a liability 
of $29.3 million is reflected in our consolidated financial statements as noncurrent liabilities. The amount recognized in accumulated 
other  comprehensive  income  was  a  net  loss  of  $17.0 million  and  the  weighted-average  discount  rate  assumption  used  to  determine 
benefit obligations as of December 31, 2009 was 5.7%. 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 $2.3 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 
$0.8 million. The asset value of the defined benefit plan has been volatile in recent months 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,  2009,  our  outstanding  debt  under  our  interest-bearing  credit  agreements 
was  $438.2 million,  including  $135.1 million  principal  amount  of  convertible  notes  with  a  fixed  interest  rate  of  2.25%  and 
$296.6 million under our “no net cost” loan. Based on an increase or decrease in interest rates by 1.0% for the year, our annual interest 
rate expense would increase or decrease by approximately $0.1 million due to the fact that any increase in interest expense related to 
our “no net cost” loan will be offset by interest earned on our ARS portfolio. 

          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 2009. A significant increase in 
inflation could affect future performance. 

- 51 - 

          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. 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.

Item 9.  Changes In and Disagreements With Accountants on Accounting and Financial Disclosure

          Not Applicable. 

Item 9A. 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  from  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, 2009. 

          Moss  Adams  LLP,  an  independent  registered  public  accounting  firm,  has  audited  and  reported  on  the  consolidated  financial 
statements of Diodes Incorporated and on the effectiveness of our internal control over financial reporting. The report of Moss Adams 
LLP is contained in this Annual Report. 

Changes in Controls over Financial Reporting 

          There  was  no  change  in  our  internal  control  over  financial  reporting,  known  to  the  Chief  Executive  Officer  or  the  Chief
Financial Officer that occurred during the last fiscal quarter covered by this report that has materially affected, or is reasonably likely 
to materially affect, our internal control over financial reporting.

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, 2008 and 2009, and the related consolidated statements of income, stockholders’ equity and cash flows for each of the 
years in the three-year period ended December 31, 2009. We also have audited the Company’s internal control over financial reporting 
as  of  December 31,  2009,  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, 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  financial  statements,  assessing  the  accounting  principles  used  and  significant  estimates  made  by
management,  and  evaluating  the  overall  financial  statement  presentation.  Our  audit  of  internal  control  over  financial  reporting
included 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, 2008 and 2009, and the results of their operations and their cash 
flows  for  each  of  the  years  in  the  three-year  period  ended  December 31,  2009,  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, 2009, based on criteria established in Internal Control – 
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. 

As discussed in Note 2 to the consolidated financial statements, the Company changed its method of accounting for its convertible
debt instruments with the adoption of the guidance originally issued in FSP APB 14-1, Accounting for Convertible Debt Instruments 
That  May  Be  Settled  in  Cash  Upon  Conversion  (Including  Partial  Cash  Settlement)    (codified  in  FASB  ASC  Topic  470,  Debt), 
effective  January 1,  2009.  As  discussed  in  Note  5  to  the  consolidated  financial  statements,  the  Company  adopted  Statement  of 
Financial Accounting Standards No. 157, Fair Value Measurements  (codified in FASB ASC Topic 820, Fair Value Measurements 
and  Disclosures)  effective  January 1,  2008,  for  financial  assets  and  liabilities,  and  January 1,  2009,  for  nonfinancial  assets  and 
liabilities.

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 designer, 
manufacturer and supplier of high-quality, application specific standard products within the broad discrete 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, amplifiers and comparators, Hall effect sensors 
and  temperature  sensors,  power  management  devices  (including  LED  drivers),  DC-DC  switching  and  linear  voltage  regulators, 
voltage references, special function devices (including USB power switch, load switch, voltage supervisor and motor controllers) and 
silicon wafers used to manufacture these products. The products are sold primarily throughout North America, Asia 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. 

          During 2007, the Company undertook an internal restructuring whereby its foreign subsidiaries were structured under its newly 
formed, wholly owned Netherlands holding company, Diodes International B.V. In addition, Shanghai Kai Hong Electronic Co., Ltd.
and Shanghai Kai Hong Technology Co., Ltd. were structured under Diodes Hong Kong Holding Company Limited., a newly formed, 
wholly owned subsidiary of Diodes International B.V. The primary purpose of this internal restructuring was for treasury management 
and tax planning functions. 

          In connection with the Company’s acquisition of Zetex plc (“Zetex”) in June 2008, the Company formed Diodes Holdings U.K. 
Limited and Diodes Investment Company, which are the holding companies for Diodes Zetex Limited and its subsidiaries. See Note 3
for  additional  information  regarding  the  Company’s  acquisition  of  Zetex  and  Exhibit 21  “  Subsidiaries  of  the  Registrant”    of  this 
Annual Report for additional information regarding the Company’s subsidiaries. 

          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 for sales to distributors using the “sell in” model, which is when product is sold to the 
distributor. 

          Certain distributors and other customers have limited rights of return and/or are entitled to price adjustments on inventory held 
in the distributors’ stock or upon sale to end customers. The Company reduces revenue in the period of sale for estimates of product 
returns,  distributor  price  adjustments  and  other  allowances,  the  majority  of  which  are  related  to  our  U.S.  operations.  Our  reserve 
estimates are based upon historical data as well as projections of revenues, 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 revenues. Revenue is reduced in the period of sale for estimates of product returns and other allowances 
including distributor adjustments, which were approximately $10.7 million, $12.5 million and $12.8 million in 2007, 2008 and 2009, 
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.

NOTE 1 — SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) 

          Short-term  investments  —  The  Company’s  short-term  investments  consisted  primarily  of  auction  rate  securities  (“ARS”), 
which are classified as trading securities. On October 29, 2008, the Company entered into a settlement with UBS AG and affiliates
(“UBS AG”), in which the Company was given the option to “put” the ARS portfolio back to UBS AG at any time between June 30, 
2010 and July 2, 2012 at par value. 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. The Company classified the “put” option as a short-term investment as it is a 
free standing instrument tied to the ARS portfolio. As trading securities, both the ARS and the “put” option are recorded at fair value 
and gains and losses are recognized in the consolidated statements of income. 

          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 allowance indicated in the 
following table:

          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,  both 
finished  goods  and  raw  materials,  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.  Due  to  abnormally  low  production  levels  as  of  December 31,  2008, 
approximately $1.1 million of fixed costs related to excess manufacturing capacity were expensed and not capitalized into inventory.

          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.

(Amounts in thousands except per share data) 

NOTE 1 — SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) 

          Goodwill  and  other  intangible  assets  —  Goodwill  is  the  cost  of  an  acquisition  less  the  fair  value  of  the  net  assets  of  the 
acquired  business.  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.  All  of  the  Company’s 
intangible assets are subject to amortization and amortized on a straight-line basis over their estimated period of benefit. The Company 
periodically evaluates the recoverability of these intangible assets by determining whether the unamortized balances can be recovered 
through undiscounted future net cash flows of the related assets and takes into account events or circumstances that warrant revised 
estimates of useful lives or that indicate that impairment exists. No impairment of intangible assets has been identified during any of 
the periods presented. The weighted average amortization period for intangible assets is approximately 8.2 years. 

          Convertible  Senior  Notes  —  On  January 1,  2009,  the  Company  changed  how  it  accounted  for  its  2.25%  convertible  senior 
notes due 2026 (“Notes”) as a change in accounting principle. The change in accounting principle required all adjustments to be made 
retrospectively as of the date of issuance for the Notes and therefore, all periods presented reflect the retrospective adjustments. The 
Notes may be settled for cash upon conversion. As such, the Company 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 the Company’s 
nonconvertible 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  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 the Company refers to as amortization of debt discount, over the expected life of the Notes using the effective interest method. 
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, 2009, 21 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 $1.0 million at December 31, 2009. 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, 2009, the Company
expects the remaining carrying value of assets to be recoverable. 

          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. 

          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.

NOTE 1 — SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) 

          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 $2.4 million, $2.4 million and $2.9 million for the years ended December 31, 2007, 2008
and 2009. 

          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, are recorded at their estimated fair values with changes in fair value reflected in the 
consolidated statements of income. 

          Derivative  financial  instruments  —  The  Company  uses  derivative  instruments  to  manage  some  of  its  exposures  to  foreign 
currency  risks.  In  connection  with  the  acquisition  of  Zetex,  the  Company  acquired  forward  exchange  contracts  and  designated  the
contracts  as  foreign-currency  cash  flow  hedges.  These  contracts  were  meant  to  reduce  the  potentially  adverse  effects  of  foreign-
currency exchange rate fluctuations that occur from sales denominated in currencies other than the British Pound (“GBP”), which is 
the functional currency of Zetex. Ineffective portions of changes in the fair value of the cash flow hedges are recognized in earnings. 
In  addition,  if  a  cash  flow  hedge  should  be  discontinued  because  it  is  probable  the  original  transaction  will  not  occur,  the  net
unrealized gain or loss will be recognized in earnings. Hedge ineffectiveness had no material impact on earnings in 2008 or 2009. As 
of December 31, 2009, the Company no longer had foreign-currency cash flow hedges as they all matured during 2009. In addition,
the Company has no immediate plans to hedge its cash flow via the purchase of additional forward foreign exchange contracts. 

          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, 2007, 2008 and 2009 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.

NOTE 1 — SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) 

          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 as the functional currency at Diodes Taiwan Inc.
and Anachip Corp. and the GBP as the functional currency at Diodes Zetex Limited 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 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. 

          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  income  are  foreign 
exchange losses of $0.6 million, $6.7 million and $4.7 million for the years ended December 31, 2007, 2008 and 2009, 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,
2008 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  venture  —  Investment  in  joint  ventures  over  which  the  Company  has  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, 2008 and 2009, the value of the Company’s investment in 
joint venture of $0.6 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 is 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 gain or (loss) was $0.9 million, 
$(48.4) million and $(48.3) million at December 31, 2007, 2008 and 2009, respectively.

          Reclassifications  —  Certain  amounts  from  prior periods have been reclassified  to  conform  to  the  current  years’  presentation 
and the retrospective adjustments associated with the change in accounting principle. 

          Recently  issued  accounting  pronouncements  —  In  December 2009,  the  Financial  Accounting  Standards  Board  (“FASB”) 
issued  Accounting  Standards  Update  (“ASU”)  2009-17,  Consolidations  (Topic  810)  —  Improvements  to  Financial  Reporting  by 
Enterprises Involved with Variable Interest Entities, which codifies FASB Statement No. 167, Amendments to FASB Interpretation 
No. 46(R).  ASU  2009-17  represents  a  revision  to  former  FASB  Interpretation  No. 46  (Revised  December 2003),  Consolidation  of 
Variable  Interest  Entities,  and  changes  how  a  reporting  entity  determines  when  an  entity  that  is  insufficiently  capitalized  or  is  not 
controlled  through  voting  (or  similar  rights)  should  be  consolidated.  The  determination  of  whether  a  reporting  entity  is  required  to 
consolidate another entity is based on, among other things, the other entity’s purpose and design and the reporting entity’s ability to 
direct  the  activities  of  the  other  entity  that  most  significantly  impact  the  other  entity’s  economic  performance.  ASU  2009-17  also 
requires  a reporting  entity  to  provide  additional  disclosures  about  its  involvement  with  variable  interest  entities  and  any  significant 
changes in risk exposure due to that involvement. A reporting entity will be required to disclose how its involvement with a variable 
interest  entity  affects  the  reporting  entity’s  financial  statements.  ASU  2009-17  is  effective  for  fiscal  years  beginning  after 
November 15, 2009. Early adoption is not permitted. The Company is currently evaluating the future impacts and required disclosures
of this pronouncement.

          In  December 2009,  the  FASB  issued  ASU  2009-16,  Transfers  and  Servicing  (Topic  860)  -  Accounting  for  Transfers  of 
Financial  Assets,  which  codifies  FASB  Statement  No. 166,  Accounting  for  Transfers  of  Financial  Asset,  an  amendment  to  SFAS 
No.140    into  the  ASC.  ASU  2009-16  will  require  more  information  about  transfers  of  financial  assets,  including  securitization 
transactions, and where entities have continuing exposure to the risks related to transferred financial assets. Among other things, ASU 
2009-16 (1) eliminates the concept of a “qualifying special-purpose entity”, (2) changes the requirements for derecognizing financial 
assets,  and  (3) enhances  information  reported  to  users  of  financial  statements  by  providing  greater  transparency  about  transfers  of 
financial  assets  and  an  entity’s  continuing  involvement  in  transferred  financial  assets.  ASU  2009-16  is  effective  for  fiscal  years 
beginning  after  November 15,  2009.  Early  adoption  is  not  permitted.  The  Company  is  currently  evaluating  the  future  impacts  and 
required disclosures of this pronouncement. 

          In  October 2009,  the  FASB  published  FASB  ASU  2009-15,  Accounting  for  Own-Share  Lending  Arrangements  in 
Contemplation  of  Convertible  Debt  Issuance  or  Other  Financing.  ASU  2009-15  includes  amendments  to  ASC  Topic  470,  Debt, 
(Subtopic 470-20), and ASC Topic 260, Earnings per Share (Subtopic 260-10), to provide guidance on share-lending arrangements 
entered into on an entity’s own shares in contemplation of a convertible debt offering or other financing. ASU 2009-15 is effective for 
fiscal years beginning after December 15, 2009, and interim periods within those fiscal years for arrangements outstanding as of the 
beginning of those years. Retrospective application is required for such arrangements. The provisions of ASU 2009-15 are effective 
for  arrangements  entered  into  on  (not  outstanding)  or  after  the  first  reporting  period  that  begins  on  or  after  June 15,  2009.  Certain 
transition disclosures are also required. Early adoption is not permitted. The provisions of ASU 2009-15 are not expected to have a 
material impact on the Company’s consolidated financial statements. 

          In September 2009, the FASB published FASB ASU No. 2009-12, Fair Value Measurements and Disclosures (Topic 820) — 
Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent). ASU 2009-12 amends ASC Subtopic

investments on the basis of the net asset value per share of the investment (or its equivalent). It also requires new disclosures, by major 
category  of  investments,  about  the  attributes  includes of  investments  within  the  scope of  this  amendment  to  the  Codification.  ASU
2009-12 is effective for interim and annual periods beginning after December 15, 2009. Early adoption is permitted. The provisions of 
ASU 2009-12 are not expected to have a material impact on the Company’s consolidated financial statements.

NOTE 2 — CHANGE IN ACCOUNTING PRINCIPLE 

          On January 1, 2009 the Company changed how it accounted for its Notes as a change in accounting principle. As a result, the 
Company  adjusted  its  December 31,  2008  consolidated  balance  sheet  and  its  consolidated  statements  of  income,  consolidated 
statements  of  equity  and  consolidated  statements  of  cash  flows  for  the  years  ended  December 31,  2007  and  2008  to  reflect  the 
retrospective application required by the change in accounting principle. Issuers of instruments, such as convertible debt instruments, 
should separately account for liability and equity components in a manner that will reflect the entity’s nonconvertible debt borrowing 
rate.  All  adjustments  were  made  retrospectively  as  of  the  date  of  issuance  of  the  Company’s  Notes  and  therefore,  the  financial 
statements are presented as if the Notes have always been accounted for in this manner. See Note 11 for additional information.

          In addition, on January 1, 2009, the Company changed how it classifies its noncontrolling interests (“NCIs”) on its consolidated 
financial statements. As a result, the Company adjusted its December 31, 2008 consolidated balance sheet to reflect the retrospective
application required with the change in accounting principle. This change in accounting principle indicates, among other things, that: 
NCIs  (previously  referred  to  as  minority  interests)  be  treated  as  a  separate  component  of  equity,  not  as  a  liability;  increases  and 
decreases in the parent’s ownership interest, that leaves control intact, be treated as equity transactions, rather than as step acquisitions 
or dilution gains or losses; and losses of a partially owned consolidated subsidiary be allocated to the NCIs even when such allocation 
might  result  in  a  deficit  balance.  The  change  in  accounting  principle  requires  changes  to  certain  presentation  and  disclosure 
requirements.  The  provisions  are  to  be  applied  to  all  NCIs  prospectively,  except  for  the  presentation  and  disclosure  requirements,
which  are  to  be  applied  retrospectively  to  all  periods  presented.  Therefore,  NCIs  of  $9.5 million  as  of  December 31,  2008  were 
reclassified to equity, a change from its previous classification between liabilities and stockholders’ equity. 

          The adjustments made to the December 31, 2008 balance sheet are as follows:

          The material retrospective adjustments caused by both changes to the Company’s consolidated statements of equity for the years 
ended  December 31,  2007  and  2008  were  to  break  out  total  equity  between  total  Diodes  Incorporated  stockholders’  equity  and 
noncontrolling interest and to adjust the December 31, 2006 additional paid-in capital for the impact of the issuance of the Notes. The 
retrospective  adjustments  caused  by  both  changes  to  the  Company’s  consolidated  statements  of  cash  flows  for  the  years  ended 
December 31, 2007 and 2008 were to adjust separate line items within cash flows from operating activities, which did not affect the 
original net reported amounts for operating activities, investing activities or financing activities.

NOTE 3 — BUSINESS ACQUISITIONS 

          Zetex Acquisition — On June 9, 2008, the Company completed the acquisition of all the outstanding ordinary capital stock of 
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: 

Purchase price (cost of shares) 
Acquisition related costs 
Total purchase price 

$ 176,138
4,054 
$ 180,192

          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. See Note 11 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 
assumed at the date of acquisition:

          Subsequent to the acquisition, the Company evaluated and adjusted its inventory for a reasonable profit allowance in accordance 
with SFAS No. 141,  Business Combinations , 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. 

          For the year ended December 31, 2008 and 2009, approximately $10.7 million and $3.9 million, respectively, has been recorded 
as amortization expense associated with the identified intangible assets, including $7.9 million for IPR&D during 2008. Amortization 
expense associated with these 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 4 — 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 British
Pound, 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. 

          These  forward  exchange  contracts  were  recognized  on  the  balance  sheet  at  their  fair  value.  Unrealized  gain  positions  are 
recorded  as  assets  and  unrealized  loss  positions  are  recorded  as  liabilities.  Changes  in  the  fair  values  of  the  outstanding  forward 
exchange contracts that are highly effective are recorded in other comprehensive income or loss until the forward exchange contracts 
are  settled.  Changes  in  the  fair  values  of  the  forward  exchange  contracts  assessed  as  not  effective  as  hedging  instruments  are 
recognized  in  earnings  in  the  current  period.  Results  of  ineffective  hedges  are  recorded  as  expense  in  the  consolidated  condensed
statements of operations in the period in which they are determined to be ineffective. 

          The  Company  assesses  both  at  the  inception  of  the  hedge  and  on  an  ongoing  basis,  whether  the  derivatives  that  are  used  in 
hedging transactions have been highly effective in offsetting changes in the cash flows of hedged items and whether those forward 
exchange contracts are expected to remain highly effective in future periods. For all periods presented, there were no gains or losses 
excluded from the assessment of effectiveness. 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. 

          As  of  December 31,  2009,  the  Company  no  longer  had  forward  contracts  as  they  matured  during  2009.  As  of  December 31, 
2008,  foreign  exchange  contracts  classified  as  derivates  designated  as  hedging  instruments  included  in  other  liabilities  was 
approximately $2.8 million. For the year ended December 31, 2008, the Company had net foreign exchange hedge-related transaction
losses  of  $1.5 million  related  to  hedging  the  Zetex  acquisition  purchase  price  and  deferred  net  unrealized  losses  on  outstanding
forward exchange contracts recorded as other comprehensive loss of $4.5 million (net of tax).

(Amounts in thousands except per share data) 

NOTE 5 — FAIR VALUE MEASUREMENTS 

          On  January 1,  2008,  the  Company  adopted  the  methods  of  fair  value  in  accordance  with  GAAP  for  its  financial  assets  and
liabilities and on January 1, 2009 for its nonfinancial assets and liabilities. 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 have 
been 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 is subject to uncertainties that are difficult to predict and the future actual market prices may 
differ materially. See Note 6 for additional information regarding the Company’s ARS portfolio.

(Amounts in thousands except per share data) 

NOTE 5 — FAIR VALUE MEASUREMENTS (Continued) 

          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 is a free standing instrument and the rights are not transferable, the existence of the “put” option 
does 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 and the Company will continue to determine the fair value of the ARS portfolio without consideration of 
the “put” option. 

          Upon  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 will be included in the consolidated statements of 
income, thereby creating accounting symmetry at both inception of the settlement and until the Company exercises its “put” option. 
See Notes 6 and 11 for additional information regarding the Company’s settlement with UBS AG.

          Since the failure of the auctions for the ARS market, through December 31, 2009, the underlying institutions have repurchased 
approximately $24.0 million of the Company’s ARS at par value, the proceeds of which have been applied against the “no net cost”
loan. During January 2010, an additional $55.3 million ARS were repurchased at par by the issuers, bringing the total ARS par value 
to $241.3 million as of January 31, 2010. 

          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,  2008  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  are  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 have prevented the Company and
other investors 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, resulting in the Company continuing to hold 
these securities. 

          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 meets 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 is 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  is  classified  as  a  short-term  investment  as  it  is  a  free
standing  instrument  tied  to  the  ARS  portfolio,  which  are  also  classified  as  short-term  investments.  See  Note  5  for  additional 
information regarding fair value measurements of the Company’s put option. 

          Since the Company transferred its ARS portfolio from available-for-sale securities category to trading securities category and 
the  Company  made  the  fair  value  election  for  the  “put”  option,  all  future  fair  value  changes  for  both  will  be  included  in  the 
consolidated statements of income, thereby creating accounting symmetry at both inception of the settlement and until the Company 
exercises its “put” option. 

          The Company continues to earn interest on its ARS at a weighted average rate of approximately 1.4% of as December 31, 2009, 
which it is currently collecting. The weighted average maximum contractual default rate is 17.3%.

NOTE 6 — SHORT-TERM AND LONG-TERM INVESTMENTS (Continued) 

          The  Company’s  ARS  are  primarily  backed  by  student  loan  association  bonds.  None  of  the  Company’s  investments  are 
collateralized mortgage obligations or are any other type of mortgage-backed or real estate-backed security. 

          As of December 31, 2009, approximately 98.6%, or $292.5 million, of the $296.6 million par value ARS are collateralized by 
higher  education  funded  student  loans  that  are  supported  by  the  federal  government  as  part  of  FFELP.  The  Company  continues  to 
believe that the credit quality of these securities are high based on this guarantee. The following table shows a natural grouping of the 
FFELP guaranteed securities, as well as the percentage of the ARS portfolio guaranteed by FFELP.

NOTE 11 — BANK CREDIT AGREEMENTS AND LONG-TERM DEBT 

          Lines of credit — The Company  maintains credit facilities with several financial institutions through its entities in the U.S., 
Europe  and  Asia  totaling  $66.2 million.  On  November 25,  2009  the  Company  entered  into  a  credit  agreement  (“the  Credit 
Agreement”) with Bank of America, N.A. (“Bank of America”). 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 24, 2010 (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) we 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;  (b) we  and  our  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) we and our subsidiaries shall not make any Investments 
except  as  specified  in  the  Credit  Agreement;  (d) we  and  our  subsidiaries  shall  not  create,  incur,  assume  or  suffer  to  exist  any
Indebtedness except as specified in the Credit Agreement; (e) we and our subsidiaries shall not dissolve or merge or consolidate with 
or into another entity except as specified in the Credit Agreement; (f) we and our subsidiaries shall not make any Disposition except as 
specified  in  the  Credit  Agreement;  (g) we  and  our  subsidiaries  shall  not  make  any  Restricted  Payment,  or  issue  or  sell  any  Equity 
Interests, except as specified in the Credit Agreement; (h) we and our subsidiaries shall not engage in any material line of business 
substantially different from those lines of business that are currently conducted by us and our subsidiaries; (i) we and our subsidiaries 
shall not enter into any transaction of any kind with any Affiliate of ours except as specified in the Credit Agreement; (j) we and our 
subsidiaries shall not enter into certain burdensome Contractual Obligations except as specified in the Credit Agreement; and (k) we 
and our 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, 2009, we were in compliance with the bank covenants. 

          The  credit  unused  and  available  under  the  various  facilities  as  of  December 31,  2009,  was  $58.6 million  (net  of  $2.8 million

          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. 

          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, 2009 are $3.0 million for each year from 2010 through 2014. Future minimum payments related to the Notes as of 
December 31,  2009  for  2015  and  thereafter  include  $32.7 million  in  interest  and  $135.1 million  in  principal  for  a  total  of 
$167.8 million.

NOTE 11 — BANK CREDIT AGREEMENTS AND LONG-TERM DEBT (Continued) 

          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
accounting literature and concluded that none of these features should be separately accounted for as derivatives. 

          On January 1, 2009, the Company changed how it accounted for its Notes as a change in accounting principle, which issuers of 
instruments similar to the Company’s Notes should allocate a portion of the proceeds received from the issuance of the Notes between 
an liability and equity component by determining the fair value of the liability component using the Company’s nonconvertible debt 
borrowing  rate.  Previous  guidance  provided  for  accounting  of  this  type  of  convertible  debt  instruments  entirely  as  debt.  All 
adjustments are required to be made retrospectively as of the date of issuance of the Notes and therefore, will be treated as if the Notes 
have always been accounted for in accordance with this pronouncement. See Note 2 for additional information regarding the change in 
accounting principle.

NOTE 11 — BANK CREDIT AGREEMENTS AND LONG-TERM DEBT (Continued) 

          “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  3  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 is 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.

NOTE 14 — STOCKHOLDERS’ EQUITY 

          As  of  December 31,  2009,  the  Company  had  approximately  43.7 million  common  shares  outstanding.  During  2009,  shares 
outstanding  increased  by  approximately  2.6 million  shares,  primarily  due  to  approximately  1.8 million  shares  issued  in  conjunction 
with exchanging shares for Notes and approximately 0.8 million shares issued in conjunction with share-based plans. 

          Additional  paid-in  capital  increased  approximately  $41.3 million  in  the  year  ended  December  31,  2009,  primarily  due  to
approximately $10.9 million in share-based compensation expense and approximately $29.4 million in conjunction with issuing shares 
in exchange for Notes. 

          In addition, in connection with the change in accounting principle and the retrospective application, additional paid-in capital 
was increased by approximately $34.3 million as of October 12, 2006 to reflect the equity component of the Notes. 

NOTE 15 — 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 $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.

NOTE 16 — INCOME TAXES (Continued) 

          For  the year  ended December 31, 2007,  the  Company  reported domestic  and foreign pre-tax  income/(loss) of  $(12.2)  million 
and  $74.0 million,  respectively.  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 of $(46.8) million and $57.9 million, respectively. 

          The Company’s global presence requires us 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, respectively. 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  received  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 25% and 20% income tax rate in 2009 and 2010, respectively. 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. Beginning 2011, 
Anachip Corp.’s earnings will be subject to statutory Taiwan income tax. 

          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%,  its  earnings  in  Hong  Kong  are  subject  to  a  16.5%  tax  rate  and  its  earnings  in 
Germany are subject to a 30% tax rate. 

          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% in 
both 2008 and 2009. For 2010, the Company expects a tax rate of 15% for both subsidiaries. 

          The impact of tax holidays decreased the Company’s tax expense by approximately $11.2 million, $6.6 million and $7.4 million 
for the years ended December 31, 2007, 2008 and 2009, respectively. The benefit of the tax holidays on basic and diluted earnings per 
share for the year ended December 30, 2007 was approximately $0.28 and $0.26, 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  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  2006.  The  Internal
Revenue Service has contacted the Company regarding an examination for the tax year ended 2006. 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  2003.  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.

NOTE 16 — INCOME TAXES (Continued) 

          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, 

2008 
$ 4,122

(1,451)
$  3,706    

2009
$ 3,706
   4,935
(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, 2008 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 
Share based compensation and others

          Funds repatriated from foreign subsidiaries to the U.S. may be subject to federal and state income taxes. As of January 1, 2007, 
the Company had accrued $3.3 million for U.S. taxes on future dividends from its foreign subsidiaries. With the establishment of the 
holding  companies  in 2007,  the  Company  intends  to  permanently  reinvest  overseas  all  of  its  earnings  from  its  foreign  subsidiaries.
Accordingly, the $3.3 million liability was reversed during 2007, and U.S. taxes are no longer being recorded on undistributed foreign 
earnings.  As  of  December 31,  2009,  the  Company  has  undistributed  earnings  from  its  non-U.S.  operations  of  approximately 
$164 million  (including  approximately  $24 million  of  restricted  earnings  which  are  not  available  for  dividends).  Additional  federal 
and state income taxes of approximately $39 million would be required should such earnings be repatriated to the U.S. 

          At December 31, 2009, the Company had federal and state tax credit carryforwards available to offset future regular income and 
partially  offset  alternative  minimum  taxable  income  of  approximately  $16.8 million  and  $0.6 million,  respectively.  The  federal  tax
credit  carryforwards  began  to  expire  in  2009  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  $0.6 million  and  $3.9 million  during  the  years  ended 
December 31, 2008 and 2009, respectively. 

          At  December 31,  2009,  the  Company  had  federal  and  state  net  operating  loss  (“NOL”)  carryforwards  of  approximately 
$50.0 million and $48.0 million, respectively, available to offset future regular and alternative minimum taxable income. The federal 
NOL  carryforwards  will  begin  to  expire  in  2012  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 has not recorded tax benefits related to the exercise of non-qualified stock options and the disqualified disposition 
of incentive stock options. The tax benefits of approximately $8.8 million of NOLs related to stock option exercises in 2008 and 2009 
will be credited to additional paid-in capital when realized.

NOTE 17 — 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 $0.6 million and $1.0 million for the year ended 
December 31,  2008  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, 2008 
and 2009:

          Based on an actuarial study performed as of December 31, 2009, the plan is under-funded by approximately $29.3 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 $17.1 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,  2009,  the  plans  total  recognized  loss  increased  by  $15.8 million.  The  variance 
between the actual and expected return to plan assets during 2009 decreased the total unrecognized net loss by $4.5 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, 
2009 the average term was 15 years. The annual amortization amount is expected to be approximately $0.6 million per year.

NOTE 17 — EMPLOYEE BENEFIT PLANS (Continued) 

          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 taking 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 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.  The  plan  does  not  hold  any  level  3  securities.  See  Note  5  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.

NOTE 17 — EMPLOYEE BENEFIT PLANS (Continued) 

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  of  22.5%  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,  2007,  2008  and  2009,  total  amounts  expensed  under  these  plans  were  approximately 
$2.9 million, $2.0 million and $2.3 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,  2009,  these  investments  totaled  approximately 
$2.8 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, 1969 Incentive Bonus Plan, and 2001 Omnibus Equity Incentive 
Plan.

NOTE 18 — SHARE-BASED COMPENSATION 

          The following table shows the total compensation cost charged against income for share-based compensation plans, including

          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 2007, 2008 and 2009 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 
Expected term (years) 
Risk free interest rate 
Forfeiture rate

N/A

          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  2009,  the  expected  volatility  for  officers  and  the  Board  is  57.89%,  while  the  expected  volatility  for  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 2009, the 
expected term for officers and the Board is 7.6 years, while the expected term for 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  2007,  2008  and  2009  was  $14.70,  $16.70,  and  $9.34,
respectively.  The  total  cash  received  from  option  exercises  was  $7.6  million,  $3.0 million  and  $1.5 million  during  2007,  2008  and
2009, respectively.

          For  the  years  ended  December 31,  2007,  2008  and  2009,  stock  option  expense  was  $5.6  million,  $4.0 million  and  $3.6, 
respectively.

          At  December 31,  2009,  unamortized  compensation  expense  related  to  unvested  options,  net  of  estimated  forfeitures,  was
approximately $8.0 million. The weighted average period over which share-based compensation expense related to these options will

NOTE 18 — SHARE-BASED COMPENSATION (Continued) 

          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 
April 14, 2015.

NOTE 20 — 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 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  operations  include  the  domestic  operations  in  Asia,  North  America  and  Europe.  Prior  to  the  acquisition  of 
Zetex, in June 2008, European operations were consolidated into the North America operations, which accounted for approximately
4.2% of total sales for the year ended December 31, 2007.

(1)    Net  income  for  the  three  months  ended  September 30,  2008  was  affected  by  purchase  price  accounting  adjustments  in 
connection with the acquisition of Zetex, primarily due to one-time non-cash expenses related to acquired intangible IPR&D and 
inventory adjustment for reasonable profit allowance. 

(2)    The amounts for fiscal 2007 and 2008 were adjusted for the retrospective application of a change in accounting principle and
from previously reported amounts on Form 10-Q due to a change in tax rates used to compute deferred income taxes. Amounts 
adjusted are not deemed material. 

Note: The sum of the quarterly earnings per share may not equal the full year amount, as the computations of the weighted average
number of common shares outstanding for each quarter and for the full year are performed independently.

company’s regulations. 

2. Yuan Hao agrees, upon receiving the response from the government and related agencies on the electricity usage application and

Power Facility, to timely request the power company to commence the construction for providing electricity in accordance with power 
company’s regulations and duly pay for such construction to the power company. 

4. If it is necessary to make other applications and/or procedures during the Power Facility application, construction, change of name 
procedures, or transfer of ownership procedures, Yuan Hao agrees, in accordance with the demand of DSH, to timely complete all of
the related applications and/or procedures. If due to any reasons not caused by Yuan Hao that the Power Facility’s change of name or 
transfer of ownership procedures cannot be completed, the Power Facility shall still be used solely and exclusively by DSH, and DSH 
shall still have the ownership of the Power Facility. Yuan Hao has no right to transfer or lease the Power Facility to a third party, and 
Yuan  Hao  has  the  responsibility  to  protect  the  completeness  of  the  Power  Facility.  If  the  issues  of  unable  to  change  the  name  or

of ownership of the Power Facility as well as other related procedures. 

5. On  the  total  cost  of  the  construction of  the  Power  Facility  and  the  method  of payment,  Yuan  Hao  shall  provide detailed  pricing 
report and, upon DSH’s review and approval, confirm such pricing report by signing another agreement with DSH. 

6.  Both  Parties  agree  to  sign  the  agreement  on  the  total  cost  of  the  construction  of  the  Power  Facility  and  the  method  of  payment 
within a month after the government or related government agencies approved the construction of the Power Facility. 

7. During the process of the Power Facility application, construction, change of name procedures, or transfer of ownership procedures, 
DSH agrees to provide all the necessary related assistance and cover all the related expenses to Yuan Hao as well as provide all the 
related facilities in accordance with Yuan Hao’s demand. 

8.  DSH  agrees  that  it  shall  pay  for  all  the  power  usage  fees  and  other  related  expenses  generated  upon  the  operation  of  the  Power
Facility.

9.  If  there  is  any  change  to  the  management  of  Yuan  Hao,  Yuan  Hao  must  immediately  notify  DSH  and  agree  to  keep  the

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,  restructuring  costs,  gain  on  extinguishment  of  debt, 
forgiveness of debt, amortization of debt discount and taxes on repatriation of earnings. Excluding restructuring costs, forgiveness of debt, gain on 
extinguishment  of  debt  and  taxes  on  repatriation  of  earnings  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. 

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, restructuring costs, gain on extinguishment of debt, amortization of 
debt discount, forgiveness of debt and taxes on repatriation of earnings. Excluding restructuring costs, gain on extinguishment of debt, forgiveness of 
debt and taxes on repatriation of earnings 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 cash flow is a non-GAAP financial measure, which is calculated by taking cash flow from operations less capital 
expenditures. FCF represents the cash and cash equivalents that we are able to generate after taking into account investments 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 12, 2010.
