Dear Shareholders
Letter from our Chairman of the Board

Fiscal 2005 was another remarkable year for
Diodes. Our market position, new products
and global distribution network delivered
positive results for our investors and cus-
tomers. When Dr. Keh-Shew Lu assumed the position of
President and CEO in June of 2005, he joined a team that had
consistently outperformed its competitors, and increased the
Company’s share of the discrete semiconductor market while
creating substantial shareholder value. Dr. Lu's charter was not
to change the direction of the Company, but rather to build on
the Company’s existing strengths to take Diodes to the next
level of success. We are pleased to say that we are on track
with this endeavor.

Our corporate strategy is designed to generate profitable
growth. Our philosophy balances the fundamental responsibility
to generate profits for our shareholders with the needs of our
customers.

By this measure, 2005 was an excellent year for Diodes, Inc.

■ Revenues increased 15.6% to $214.8 million from 

$185.7 million in 2004.

■ Our gross margins improved by 190 basis points to 34.6% from 

32.7%, a year ago.

■ Net income increased 30.4% to a Company record $33.3 million, 
compared with $25.6 million a year ago, as earnings per share 
increased to $1.29 from $1.10.

■ We generated $50.1 million in cash from operations versus 

$29.3 million in 2004. 

■ Our balance sheet strengthened with cash and short-term 

investments  of nearly $114 million versus $19.0 million last year.

■ And shareholder equity more than doubled to $225.9 million 

compared with $112.1 million in 2004.

Just as importantly, 2005 was a year in which Diodes set the
stage for our next phase of corporate growth. We strengthened
our senior management team, significantly expanded our 
manufacturing capacity, extended our global sales footprint, 
and laid the groundwork to enter exciting new adjacent mar-
kets. Through our successful follow-on offering, we gained the 
financial strength to aggressively pursue strategic initiatives. 
In 2006, we intend to capitalize on those opportunities and 
hope to enjoy further success.

Sincerely,

Raymond Soong
Chairman of the Board

Letter from our New President and CEO 

It’s great to be at Diodes and I am excited to
be on this winning team. We expect to build on this
favorable momentum during fiscal 2006, as we continue to focus
on “Profitable Growth.” We plan to achieve Profitable Growth by
realizing cost efficiencies, developing innovative technology,
driving new products, and expanding our customer base.

Cost Reduction
Diodes’ modern, flexible, low-cost manufacturing in mainland
China provides us with a core strategic advantage as we 
provide our customers with the highest quality devices at 
competitive costs. In both our wafer fabrication and packaging 
facilities, the Diodes’ team is focused on achieving continuous
improvements in quality, productivity and yield. During 2005, 
we invested nearly $25 million in new manufacturing capacity,
and increased our total output by 52% to over 8 billion devices 
a year. Our flexible, customer-centered approach means that
we can quickly reconfigure this capacity as dictated by cus-
tomer requirements. As a result, we are able to deliver devices
of outstanding reliability for high-volume applications within very
tight delivery schedules. All of these factors position Diodes as
a premier supplier with our OEM customers.

Technology Innovation
As a result of our R&D efforts over the past several years,
Diodes has established a reputation as an innovation leader in
discrete technologies. The ongoing miniaturization of consumer
electronics and computing devices has created tremendous
demand for products that can help our customers achieve
enhanced performance and energy efficiency, while shrinking
printed circuit board real estate. High performance, proprietary
platforms such as our PowerDI™123, PowerDI™5 and DFN
ultra-miniature Quad Flat No-Lead packages have set new
industry standards. And we continue to break new ground in
multi-chip integration with our ASMCC (Application Specific
Multi-Chip Circuit) devices and our recently introduced series 
of Complex Arrays. These products extend our multi-chip inte-
gration capabilities with arrays that combine multiple functions
into one single, smaller, consolidated package. We have
achieved outsized returns from our investment in research and
development, and plan to increase that investment from 1.7%
of our sales in 2005 to approximately 2.5% in 2006. This will
enable us to extend our reach into analog and mixed signal
devices, which offer tremendous opportunities for profitable
growth.

New Products
During 2005, we successfully introduced over 200 new part
numbers, which have been embraced by our customers and
constituted nearly 16% of total revenues for 2005. Our applica-
tions engineers worked with our customers to make sure they
understood how they could use our products to improve the
performance and efficiency of their next generation electronic
devices. In many cases, we were able to save our customers
money while enhancing Diodes’ margins, as we migrated them
to our next generation devices such as the ASMCC. For 2006,
we expect to continue to introduce a significant number of new
products that leverage our existing breakthrough discrete 
packages, as well as other technologies that are under devel-

opment. In addition, we will soon be coming to market with a
range of new analog and power management products from 
our internal development efforts and the new linear analog
capabilities that we gained with the January 2006 acquisition
of Anachip Corporation. 

Expanded Customer Base
Diodes’ customer service culture and manufacturing excel-
lence have enabled us to build a customer base that spans
the industry leaders in computing, consumer electronics, 
communications and automotive sectors. Roughly 70% of our
sales go directly to OEM customers, while the remaining 30%
of our sales go through our network of global distributors. This
closeness to the customer enables us to be more effective in
solving design issues, meeting tight turnaround requirements,
and anticipating our customers’ future needs. In fact, our 
customers directly set the pace for our R&D focus. During
2005, we continued to expand our Asia sales and engineering
teams, while strengthening our distribution network in Europe.
Diodes’ global reach means that we can effectively work with
global manufacturers whose design, manufacturing and 
logistics span multiple countries around the world. And our
move into adjacent technologies, such as analog and mixed
signal, will enable us to deliver even more value to them.

The Next Level of Success
So what is the next phase of Diodes' growth strategy?
Acquisitions of companies with adjacent technology to our 
discrete products will be an important element of our strategy,
with an initial focus on standard analog product that would
leverage our strengths in cost efficient packaging and enable
us to rapidly build share with our existing customer base. Over
time, we intend to expand that reach into proprietary analog 
and mixed signal products that will support continued margin
improvement. 

The acquisition of Anachip fits dead center with this strategy.
Anachip’s main product focus is Power Management solutions.
They bring an excellent design team with strong capabilities 
in a range of targeted analog and power management tech-
nologies. We expect significant synergies to be obtained as
we integrate Anachip with our operations. This includes
growth opportunities from offering their devices to our global
customer base and significant cost synergies as we transition
production from the current outsourced packaging to Diodes’
state-of-the art facilities. 

Anachip is the first of what we expect will be several acquisi-
tions that enable us to accelerate our organic growth while
leveraging our innovative discrete component technology, our
world-class packaging capabilities and our sales and market-
ing channels. In broad terms, we intend to apply the same
strategy that has served us so well in the discrete market to
establish a presence and then rapidly grow our share in 
the analog and mixed signal arena. Based on input from our 
customers, we can see a wide range of opportunities for
growth in this arena in the years ahead.

PowerDI is a trademark of Diodes Incorporated.

Increasing Market Recognition
We are also pleased to report that Diodes’ market and finan-
cial success has received recognition during the past 12
months from leading publications and awards. These include:

■ Rising to 26th in Forbes Magazine’s 200 Best Small Companies 

List for 2005.

■ Ranking 10th Among Fortune Small Business Magazine’s List 

of Fastest Growing Small Companies.

■ Ranking 45th in Business 2.0 Magazine’s Fastest-Growing

Small Electronics Companies.

■ Ranking 19th in Los Angeles Business Journal’s 2005 List of 

L.A.’s Largest Technology Firms and 87th in their List of Largest 
Public Companies.

We remain cognizant that such recognition is based on superior
financial results, and our management team is focused on
sustaining our achievements going forward.

As we head into 2006, demand for discrete semiconductors
continues to be robust and Diodes is well-positioned to capture
opportunities for future growth. We are putting our strategy
into action by aggressively introducing new products, leverag-
ing our strengths in next-generation multi-chip devices, 
distinguishing ourselves through our intense customer service,
and expanding our manufacturing capacity. In the discrete
segment, we believe that we are positioned in the right markets,
with the right products, in order to fully exploit the growth
opportunities created by the ongoing miniaturization and 
convergence of computing and consumer electronics devices.
As we move into the analog and mixed signal markets, we
expect to sustain our growth while gradually moving toward
higher margined products. In summary, we look forward to
“Profitable Growth” in 2006.

We would like to close by thanking all of Diodes’ shareholders,
customers and employees for making our success possible. 
We are very pleased to make a contribution to this winning
team, and can assure our shareholders that your interests are
at the core of our philosophy for operating and growing
Diodes’ top- and bottom-line for the future.

Sincerely,

Dr. Keh-Shew Lu 
President and 
Chief Executive Officer

Business 

GENERAL 

PART I 

We are a global supplier of discrete and analog semiconductor products.  We design, manufacture and market these 
semiconductors focused on diverse end-use applications in the consumer electronics, computing, industrial, communications 
and automotive sectors.  Discrete 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  discrete  and  analog  semiconductors  provides  us  with  a  meaningful  competitive  advantage  relative  to  broadline 
semiconductor companies that provide a wider range of semiconductor products. 

Our  portfolio  of  discrete  and  analog  semiconductors  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 discrete semiconductors for applications with critical need to minimize product size while maximizing power 
efficiency and overall performance, and at a lower cost than alternative solutions.  Our product portfolio includes over 4,000 
products, and we shipped approximately 7.5 billion units in 2004 and approximately 10.2 billion units in 2005. 

We  serve  over  150  direct  customers  worldwide,  which  consist  of  original  equipment  manufacturers  (OEMs)  and

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,  industrial, 
communications 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 
three years 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  highly-skilled 
workforce at a low overall cost base while enabling us to better serve our leading customers, many of which are located in 
Asia. 

Integrated packaging expertise -- We believe that we have particular expertise in designing and manufacturing innovative 
and  proprietary  packaging  solutions  that  integrate  multiple  separate  discrete  elements  into  a  single  semiconductor  product 
called  an  array.    Our  ability  to  design  and  manufacture  highly  integrated  discrete  semiconductor  solutions  provides  our 
customers with products of equivalent functionality with fewer individual parts, and at lower overall cost, than alternative 
products.    For  example,  one  of  our  leading  diode  array  products  integrates  eight  discrete  elements  into  a  single  highly 
miniaturized package that provides four times the functionality, with less than 20% of the space requirements of the previous 
solution.  This combination of integration, functionality and miniaturization makes our products well suited for high-volume 
consumer applications such as digital audio players, notebook computers and digital cameras. 

Broad  customer  base  and  diverse  end-markets  --  Our  customers  include  leading  OEMs  such  as  Bose  Corporation, 
Honeywell  International,  Inc.,  LG  Electronics,  Inc.,  Logitech,  Inc.,  Motorola,  Inc.,  Quanta  Computer,  Inc.,  Sagem 
Communication, Samsung Electronics Co.,  Ltd.  and  Thompson,  Inc.,  as  well  as  leading  EMS  providers  such  as  Celestica, 
Inc., Flextronics International, Ltd., Hon Hai Precision Industry Co., Ltd., Inventec Corporation, Jabil Circuit, Inc., Sanmina-
SCI  Corporation  and  Solectron  Corporation.    Overall,  we  serve  over  150  direct  customers  and  over  10,000  additional 
customers  through  our  distributors,  including  leading  distributors  such  as  Arrow  Electronics,  Inc.,  Avnet,  Inc.,  Future 
Electronics  and  Yosun  Industrial  Corp.    Our  products  are  ultimately  used  in  end-products  in  a  large  number  of  markets 

3 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
served by our broad base of customers, which we believe makes us less dependent on either specific customers or specific 
end-use applications. 

Customer focused product development -- Close 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  semiconductor  marketplace.    We  believe  our  close  relationships  with  our  OEM  and  EMS 
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. 

Management continuity and experience -- We believe that the continuity of our management team is a critical competitive 
strength.  The five members of our senior management team have an average of over 12 years of service at Diodes and the 
length of their service with us has created significant institutional insight into our markets, our customers and our operations. 
In June 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 30 years of relevant industry experience.  Dr. Lu began his career at Texas Instruments, Inc. 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, Carl Wertz, has been employed by us since 1993 and has over 20 years of financial 
experience  in  manufacturing  and  distribution  industries.    Joseph  Liu,  our  Senior  Vice  President,  Operations,  joined  us  in 
1990 and has over 30 years of relevant industry experience having started his career in 1971 at Texas Instruments.  Similarly, 
Mark King, our Senior Vice President of Sales and Marketing, has been employed by us since 1991, as has Steven Ho, our 
Vice President of Asia Sales. 

OUR STRATEGY 

Our strategy is to continue to enhance our position as a global supplier of discrete semiconductor products, and to add 
analog  IC  capabilities,  which  compliment  our  current  capabilities  to  the  markets  we  serve,  such  as  power  management.    The 
principal elements of this strategy include the following: 

Continue to rapidly introduce innovative discrete and analog semiconductor products -- We intend to maintain our rapid 
pace of new discrete product introductions, especially for high-volume, growth applications with short design cycles, such as 
digital  audio  players,  notebook  computers,  flat-panel  displays,  mobile  handsets,  digital  cameras,  set-top  boxes  and  other 
consumer electronics and computing devices.  During 2005, we introduced 231 new devices in 32 different product families 
and  achieved  new  design  wins  with  over  100  OEMs.  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. 

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

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

(cid:190) Expanding existing products and developing new products in our function specific array lines, which combine 
multiple discrete semiconductor components to achieve specific common electronic device functionality at a 
low cost; and 

(cid:190) Developing new product lines, which we refer to as end-equipment specific arrays, which combine discrete 
components  with  logic  and/or  standard  analog  circuits  to  provide  system-level  solutions  for  high-volume, 
high-growth applications. 

Maintain  intense  customer  focus  --  We  intend  to  strengthen  and  deepen  our  customer  relationships.    We  believe  that 
continued  focus  on  customer  service  would  increase  our  net  sales,  operating  performance  and  overall  market  share.    To 
accomplish this, we intend to continue to closely collaborate with our customers to design products that meet their specific 
needs. A critical element of this strategy is to continue to further reduce our design cycle time in order to quickly provide our 

4 

 
 
 
 
 
 
 
 
 
 
 
customers with innovative products.  Additionally, to support our customer-focused strategy, we are continuing  to  expand 
our sales force and field application engineers, particularly in Asia and Europe. 

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.    Additionally,  we  intend  to  continue  to 
operate  our  facilities  at  high  utilization  rates  and  to  increase  product  yields  in  order  to  achieve  meaningful  economies  of 
scale. 

Pursue selective strategic acquisitions -- As part of our strategy to expand our discrete and analog 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 support our ASMCC product platform and enhance our standard and new product offerings.    

As part of our growth strategy, in December 2005, we announced the acquisition of Anachip, a fabless Taiwanese 
semiconductor company focused on analog ICs designed for specific applications, and headquartered in the Hsinchu Science 
Park in Taiwan.  This acquisition, which closed on January 10, 2006, fits in the center of our long-term strategy.  Anachip’s 
main product focus is Power Management ICs.  The analog devices they produce are used in LCD monitor/TV's, wireless LAN 
802.11 access points, brushless DC motor fans, portable DVD players, datacom devices, ADSL modems, TV/satellite set-top 
boxes,  and  power  supplies.    Anachip  brings  a  design  team  with  strong  capabilities  in  a  range  of  targeted  analog  and  power 
management technologies. 

FOLLOW-ON PUBLIC OFFERING 

During 2005, we sold 2,125,000 shares of our Common Stock in a follow-on public offering, raising approximately 
$71.7 million (net of commissions and expenses).  We used approximately $30 million of the net proceeds in connection with 
the Anachip acquisition and we intend to use the remaining net proceeds from this offering for working capital and other general 
corporate purposes, including acquisitions. 

OUR PRODUCTS 

Our product portfolio includes over 4,000 products that are designed for use in high-volume consumer devices such 
as digital audio players, notebook computers, flat-panel displays, mobile handsets,  digital  cameras  and  set-top  boxes.    We 
target and serve end-equipment  market  segments  that  we  believe  have  higher  growth  rates  than  the  overall  semiconductor 
industry. 

Our broad product line includes: 

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

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

packages, including customer specific and function specific arrays; 

(cid:190) Silicon wafers used in manufacturing these products; and 

(cid:190) Analog and mixed-signal devices through our recent Anachip acquisition 

Our discrete semiconductor products are an essential building-block of electronic circuit design and are available in 

thousands of permutations varying according to voltage, current, power handling capability and switching speed. 

Our  complex  diode  and  transistor  arrays  help  bridge  the  gap  between  discrete  semiconductors  and  integrated 
circuits.  Arrays consist of multiple discrete semiconductor devices housed in a single package.  Our discrete surface-mount 
devices, which are components that can be attached to the surface of a substrate with solder, target end-equipment categories 
with critical needs to minimize size while maintaining power efficiency and performance.

PRODUCT PACKAGING 

Our  device  packaging  technology  includes  a  wide  variety  of  surface-mount  and  leaded  types.    Our  focus  on  the 
development of smaller, more thermally efficient, and increasingly integrated packaging, is an important component of our 
product development.  We provide a comprehensive offering of miniature and  sub-miniature  packaging,  enabling  us  to  fit 
discrete 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 and weight of, and in the board space required 
for,  our  components  and  is  well  suited  for  battery-powered,  hand-held  and  wireless  consumer  applications  such  as  digital 
audio players, notebook computers, flat-panel displays, mobile handsets, digital cameras and set-top boxes. 

CUSTOMERS 

We serve over 150 direct customers worldwide, which consist of OEMs and EMS providers. Additionally, we have 
17  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.,  LG 
Electronics, Inc., Logitech, Inc., Motorola, Inc., Quanta Computer, Inc., Sagem Communication, Samsung Electronics Co., 
Ltd.  and  Thompson,  Inc.;  (ii) leading  EMS  providers,  such  as  Celestica,  Inc.,  Flextronics  International,  Ltd.,  Hon  Hai 
Precision Industry Co., Ltd., Inventec Corporation, Jabil Circuit, Inc., Sanmina-SCI Corporation and Solectron Corporation, 
who  build  end-market  products  incorporating  our  semiconductors  for  companies  such  as  Apple  Computer,  Inc.,  Cisco 
Systems,  Inc.,  Dell,  Inc.,  EMC  Corporation,  Intel  Corporation,  Microsoft  Corporation  and  Roche  Diagnostics;  and 
(iii) leading distributors such as Arrow Electronics, Inc., Avnet, Inc., Future Electronics and Yosun Industrial Corp. For 2004 
and 2005, our OEM and EMS customers together accounted for 66.3% and 69.5%, respectively, of our net sales.  

For the year ended December 31, 2004 and December 31, 2005, Lite-On Semiconductor Corporation (LSC), which 
is also our largest stockholder, (owning approximately 22.9% of our Common Stock as of December 31, 2005), accounted 
for approximately 11.1% and 9.6%, respectively, of  our  net sales.    Additionally,  other  members  of  The  Lite-On  Group  of 
companies accounted for 3.3% and 4.2% of our net sales, respectively, in 2004 and 2005.  No other customer accounted for 
10% or more of our net sales in 2004 and 2005.  Also, 17.2% and 14.7% of our net sales were from the subsequent sale of 
products  we  purchased  from  LSC  in  2004  and  2005,  respectively.  We  believe  each  member  of  The  Lite  On  Group  of 
companies makes independent purchasing decisions. 

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  to  date  has  not  been  significant. 
Generally, our customers may cancel orders on short notice without incurring a significant penalty. 

Many  of  our  customers  are  based  in  Asia.  Net  sales  by  country  consists  of  sales  to  customers  assigned  to  that 
country based on the country to which the product is shipped.  For the year ended December 31, 2005, 31.7%, 27.9%, 25.6% 
and 14.8% of our net sales were derived from China, Taiwan, the United States and all other markets, respectively, compared 
to 23.9%, 27.3%, 28.7% and 20.1%, respectively for 2004. 

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  United  States,  United  Kingdom, 
France, Germany, Taiwan and China.  We also have independent sales representatives  in  the  United  States,  Japan,  Korea, 
and Europe. We currently have distributors in the United States, Europe and Asia. 

As  of  December  31,  2005,  our  direct  global  sales  and  marketing  organization  consisted  of  over  90 employees 
operating  out  of  14 offices.  We  have  sales  and  marketing  offices  or  representatives  in  Taipei,  Taiwan;  Shanghai  and 
Shenzhen, China; Hong Kong; Derbyshire, England; Toulouse, France; Frankfurt, Germany; and we have five regional sales 
offices in the United States.  As of December 31, 2005, we also had 25 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  provides  easy  access  to  our  worldwide 
sales  contacts  and  customer  support,  and  incorporates  a  distributor-inventory  check  to  provide  component  inventory 
availability and a small order desk for overnight sample fulfillment.  Our website also provides access to investor financial 
information and our corporate governance information. 

MANUFACTURING OPERATIONS AND FACILITIES 

We  operate  three  manufacturing  facilities,  two  of  which  are  located  in  Shanghai,  China.    The  third  is  located  in 
Kansas City, Missouri.  Our facilities in Shanghai perform packaging, assembly and testing functions, and our Kansas City 
facility is a 5-inch wafer foundry. 

As of December 31, 2005, we had invested approximately $95.7 million in plant and state-of-the-art equipment in 
China. Both of our Chinese factories manufacture product for sale by our U.S. and Asian operations, and also sell to external 
customers as well.  Silicon wafers are received and inspected in a highly controlled “clean room” environment awaiting the 
assembly operation.  At 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.  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.  Our fully automated assembly machinery then molds the epoxy case around the die and 
lead-frame to produce the desired semiconductor product.  After a trim, form, test, mark and re-test operation, the parts are 
placed into special carrier housings and a cover tape seals the parts in place.  The taped parts are then spooled onto reels and 
boxed for shipment. 

Our manufacturing processes use many raw materials, including silicon wafers, copper lead frames, gold wire and 
other metals, molding compound, ceramic packages and various chemicals and gases.  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 

7 

 
 
 
 
 
 
 
 
 
 
 
 
 
  
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. 

In  the  United  States,  our  corporate  headquarters  are  located  in  a  leased  facility  in  Westlake  Village,  California, 
approximately  30 miles  from  Los  Angeles.    We  also  lease  or  own  properties  around  the  world  for  use  as  sales  offices, 
research and development labs, warehouses and logistic centers.  The size and/or location of these properties change from 
time to time based on business requirements.   Our current properties are as follows:

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 to 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, are experiencing a trend towards shorter lead-times.  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 

Although patents and trademarks have not been material to our business to date, they may become more significant 

in the future, particularly as they relate to our packaging and analog technologies. 

Currently, we do not license our patents or products. We do, however, license certain product technology from other 
companies,  but  we  do  not  consider  any  of  the  licensed  technology  to  be  material  in  terms  of  royalties.    We  believe  the 
duration and other terms of the licenses are appropriate for our current needs.

Numerous  semiconductor  manufacturers  and  distributors  serve  the  discrete  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 us.  Accordingly, in response  to  market  conditions,  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 and our flexibility and 
ability to quickly adapt to customer needs affords us competitive advantages. Nevertheless, we expect that competition with 
larger rivals will continue to be a challenge. 

ENGINEERING AND RESEARCH AND DEVELOPMENT 

Our engineering and research and development groups consist of customer and applications engineers 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 engineers work directly with our semiconductor wafer design and process engineers who craft 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 customer’s electrical and packaging requirements through their product development engineers, and then transfer those 
requirements  to  our  research  and  development  and  engineering  department,  so  that  the  customer’s  requirements  can  be 
translated, designed, and manufactured with full control, even to the elemental silicon level. 

For the years ended December 31, 2004 and 2005,  investment  in  research and  development  was  $3.4 million  and 
$3.7 million, respectively.  As a percentage of net sales, research and development expense was 1.8% and 1.7% for 2004 and 
2005, respectively.  We anticipate research and development in absolute dollars and as a percentage of net sales to increase 
as we further develop proprietary technology. 

EMPLOYEES 

As of December 31, 2005, we employed a total of 1,621 employees, of which 1,322 of our employees were in Asia, 
293  were  in  the  United  States  and  six  were  in  Europe.    None  of  our  employees  is  subject  to  a  collective  bargaining 
agreement.  We consider our relations with our employees to be good. 

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  United  States  where  our  wafer  fabrication  facility  is  located,  and  in  China  where  our 
assembly, test and packaging facilities are located.  Any of these regulations could require us to acquire equipment or to incur 
substantial  other  expenses  to  comply  with  environmental  regulations.    As  of  December  31,  2005,  there  were  no  known 
environmental claims or recorded liabilities. 

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS 

We  conduct  business  with  two  related  party  companies,  LSC  (and  its  subsidiaries  and  affiliates)  and  Keylink 
International (formerly Xing International) (and its subsidiaries).  LSC is our largest stockholder and owned 22.9% of our 
outstanding Common Stock as of December 31, 2005. Keylink International is our 5% joint venture partner in Diodes-China 
and Diodes-Shanghai.  C.H. Chen, our previous President and Chief Executive Officer, and Vice Chairman of our Board of 
Directors,  is  also  Vice  Chairman  of  LSC.    M.K.  Lu,  a  member  of  our  Board  of  Directors,  is  President  of  LSC,  while  Dr. 
Shing  Mao,  who  is  one  of  our  directors,  retired  in  2000  as  Chairman  of  the  board  of  Lite-On  Milpitas,  a  wholly-owned 
subsidiary of Taiwan Lite-On which merged with Lite-On Technology Corporation in 2002.  Dr. Mao was also a director of 

9 

 
 
 
 
 
 
 
 
 
 
 
  
 
 
  
 
 
 
LSC from 1989 to 2000.  In addition, Raymond Soong, the Chairman of our Board of Directors, is the Chairman of Lite-On 
Technology  Corporation,  a  significant  shareholder  of  LSC,  as  well  as  Chairman  of  LSC.    In  connection  with  our  2005 
follow-on  public  offering,  LSC  sold  750,000  shares  (1,125,000  split-adjusted  shares  at  December  1,  2005),  reducing  its 
holdings of our Common Stock to 5,777,187 shares (split adjusted).  We did not receive any of the proceeds from their sale 
of our Common Stock.  

The Audit Committee of our Board of Director reviews all related party transactions for potential conflict of interest 
situations,  and  approves  all  such  transactions,  in  accordance  with  such  procedures  as  it  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. 

In 2005, we sold silicon wafers to LSC totaling 9.6% (11.1% in 2004 and 10.7% in 2003) of our sales, making LSC 
our  largest  customer.    Also  for  2005,  14.7%  (17.2%  in  2004  and  17.3%  in  2003)  of  our  sales  were  from  discrete 
semiconductor  products  purchased  from  LSC  for  subsequent  sale  by  us,  making  LSC  our  largest  outside  supplier.    In 
addition, companies affiliated with LSC, which we refer to collectively as The Lite-On Group, accounted for 2.5%, 3.3% and 
4.2% of our net sales, respectively, in 2003, 2004 and 2005.  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  2003,  2004  and  2005  we 
reimbursed  this  entity  in  aggregate  amounts  of  $112,000,  $190,000  and  $288,000,  respectively,  for  these  items.    Such 
transactions are on terms no less favorable to us than could be obtained from unaffiliated third parties.  The Audit Committee 
of the Board of Directors has approved the arrangements we have with these related party transactions. 

In  December  2000,  we  acquired  a  wafer  foundry,  FabTech,  Inc.,  from  LSC.    As  part  of  the  purchase  price,  LSC 
received a subordinated, interest-bearing note receivable in a principal amount of $13.5 million, of which approximately $2.5 
million  and  $0,  respectively,  was  outstanding  as  of  December 31,  2004  and  December 31,  2005.    In  May  2002,  we 
renegotiated  the  terms  of  the  note  to  extend  the  payment  period  from  two  years  to  four  years,  and,  as  a  result,  monthly 
payments of approximately $208,000 plus interest began in July 2002.  In connection with the acquisition, LSC entered into 
a volume purchase agreement to purchase wafers from FabTech. In addition, in accordance with the terms of the acquisition, 
we also entered into several management incentive agreements with members of FabTech’s management.  The agreements 
provided members of FabTech’s management with guaranteed annual payments as well as contingent bonuses based on the 
annual  profitability  of  FabTech,  subject  to  a  maximum  annual  amount.    Any  portion  of  the  guaranteed  and  contingent 
liability paid by FabTech was reimbursed by LSC.  The final year of the management incentive agreements was 2004, with 
final payment made on March 31, 2005. LSC reimbursed us in the amount of $375,000 for each of 2002, 2003 and 2004, for 
bonuses paid by us under these management incentive agreements. 

In  2005,  we  sold  silicon  wafers  to  companies  owned  by  Keylink  International  totaling  0.6%  (0.9%  in  2004  and 
1.1%  in  2003)  of  our  sales.    Also  for  2005,  3.0%  (3.5%  in  2004  and  4.6%  in  2003)  of  our  sales  were  from  discrete 
semiconductor products purchased from companies owned by Keylink International.  In addition, Diodes-China and Diodes-
Shanghai lease their manufacturing facilities from, and subcontract a portion of their manufacturing process (metal plating 
and environmental services) to, Keylink International.  We also pay a consulting fee to Keylink International.  In 2003, 2004 
and  2005,  we  paid  Keylink  International  an  aggregate  of  $3.5 million,  $4.8 million  and  $6.6 million,  respectively,  with 
respect  to  these  items.    We  believe  such  transactions  are  on  terms  no  less  favorable  to  us  than  could  be  obtained  from 
unaffiliated third parties.  The Audit Committee of the Board of Directors has approved the contracts associated with these 
related party transactions. 

On December 20, 2005, we announced we signed a definitive stock purchase agreement to acquire Anachip Corporation, 
a Taiwanese fabless analog  IC  company,  and  headquartered  in  the  Hsinchu  Science  Park  in  Taiwan.    The  selling  shareholders 
included LSC (which owned approximately 60% of Anachip’s outstanding capital stock), and two Taiwanese venture capital firms 
(together owning approximately 20% of Anachip’s stock), as well as current and former Anachip employees. 

At December 31, 2005, we had purchased an aggregate of 9,433,613 shares (or approximately 18.9%) of the 50,000,000 
outstanding shares of the capital stock of Anachip.  On January 10, 2006, (the closing date of the acquisition) we purchased an 
additional 40,470,212 shares and therefore, we now hold approximately 99.81% of the Anachip capital stock.

Item 1A.  

Risk Factors 

RISKS RELATED TO OUR BUSINESS 

Downturns in the highly cyclical semiconductor industry or  changes  in  end-market  demand  could  affect  our  operating 
results 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.    For  example,  beginning  in  the  fourth  quarter  of  2000  and  continuing  into  2003,  the  semiconductor 
industry  experienced  order  cancellations  and  reduced  demand  for  products,  resulting  in  significant  revenue  declines,  due  to 

11 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 the discrete (and now analog) semiconductor segment of the broader semiconductor market 
and, as a result, cyclical fluctuations may affect this segment to a greater extent than they do the broader semiconductor market.  
This  may  cause  us  to  experience  greater  fluctuations  in  our  results  of  operations  than  compared  to  some  of  our  broadline 
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 operating results and financial condition. 

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

The  semiconductor  segments  of  the  semiconductor  industry  in  which  we  operate  are  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 broadline 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, International 
Rectifier  Corporation,  ON  Semiconductor  Corporation,  Philips  Electronics  N.V.,  Rohm  Electronics  USA  LLC,  and  Vishay 
Intertechnology,  Inc.    We  may  not  be  able  to  compete  successfully  in  the  future,  and  competitive  pressures  may  harm  our 
financial condition or our operating results. 

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  and  results  of 
operations. 

In 2004 and 2005, LSC, our largest stockholder and our largest customer, accounted for 11.1% and 9.6%, 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 14.7% and 17.2%, respectively, of our net sales, in 2004 and 2005.  The loss of LSC as either a 
customer or a supplier, or any significant reduction in either the amount of product it supplies to us, or the volume of orders it 
places with us, could materially harm our business and results of operations. 

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

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  facility  is  located  in  Kansas  City,  Missouri,  while  our  facilities  in  Shanghai,  China  provide 
assembly, test and packaging capabilities. Any disruption of operations at these facilities could have a material adverse effect on 
our business, financial condition and results of operations. 

12 

 
 
 
 
 
 
 
 
 
 
 
 
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  an  annual  decrease  in  average  selling  prices  for  our  products  of  3.1%  and  15.0%  for  2004  and  2005, 
respectively.  At times, average selling prices for some of our standard discrete semiconductors have been below our costs.  Our 
growth and the  profit  margins  of  our  products  will  suffer  if  we  cannot  effectively  continue  to  reduce  our  costs  and  keep  our 
product prices competitive. 

Our  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. 

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 could result in a decrease 
in net sales and loss of market share. 

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 
discrete 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 the discrete 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 harm our business. 

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 

13 

 
 
 
 
 
 
 
 
 
our  patents,  regardless  of  its  merit  or  resolution,  could  be  costly  and  divert  the  efforts  and  attention  of  our  management  and 
technical personnel.  We may not prevail in litigation given the complex technical issues and inherent uncertainties in intellectual 
property litigation. If litigation results in an adverse ruling we could be required to: 

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

infringing technology; 

(cid:190) license technology from the third party claiming infringement, which license may not be available on commercially 

reasonable terms, or at all; or 

(cid:190) relinquish  intellectual  property  rights  associated  with  one  or  more  of  our  patent  claims,  if  such  claims  are  held 

invalid or otherwise unenforceable. 

We  depend  on  third-party  suppliers  for  timely  deliveries  of  raw  materials,  parts  and  equipment,  as  well  as  finished 
products from other manufacturers, and our results of operations 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 
business and harm our results of operations and our reputation with our customers. 

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 and our ability to compete, profit margins and results of operations may suffer. 

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

(cid:190) difficulties associated with owning a manufacturing business, including, but not limited to, the maintenance and 

management of manufacturing facilities, equipment, employees and inventories and limitations on the flexibility of 
controlling overhead; 

(cid:190) difficulties in continuing expansion of our operations in Asia and Europe, because of the distance from our 

U.S. headquarters and differing regulatory and cultural environments; 

(cid:190) the need for skills and techniques that are outside our traditional core expertise; 
(cid:190) less flexibility in shifting manufacturing or supply sources from one region to another; 
(cid:190) even when independent suppliers offer lower prices, we would continue to acquire wafers from our captive 

manufacturing facility, which may result in us having higher costs than our competitors; 
(cid:190) difficulties developing and implementing a successful research and development team; and 
(cid:190) difficulties developing, protecting, and gaining market acceptance of, our proprietary technology. 

The risks of becoming a fully integrated manufacturer are amplified in an industry-wide slowdown because of the fixed 
costs associated with manufacturing facilities.  In addition, we may not realize the cost, operating and other efficiencies that we 

14 

 
 
 
 
 
 
 
 
 
 
 
 
expect from continued vertical integration.  If we fail to successfully vertically integrate our business, our ability to compete, 
profit margins and results of operations 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. 

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 FabTech, a wafer fabrication company, in order to have our 
own wafer manufacturing capabilities, and (ii) in January 2006, we acquired Anachip as an entry into standard logic markets.  
While we do not currently have any agreements in place, or any active negotiations underway, with respect to any acquisition, 
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, financial condition and results of operations.  In addition, we may not realize all of the benefits we anticipate from any 
such acquisitions.  Some of the risks that may affect our ability to integrate or realize any anticipated benefits from acquisitions 
that we may make include those associated with: 

(cid:190) unexpected losses of key employees or customers of the acquired company; 
(cid:190) bringing  the  acquired  company’s  standards,  processes,  procedures  and  controls  into  conformance  with  our 

operations; 

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

We  are  subject  to  many  environmental  laws  and  regulations  that  could  affect  our  operations  or  result  in  significant 
expenses. 

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  where  our  wafer  fabrication  facility  is  located,  and  in  China  where  our 
assembly, test and packaging facilities are located.  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, financial condition and results of 
operations.  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 share. 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.  
Although  we  conduct  environmental  due  diligence  on  properties  that  we  operate,  our  diligence  may  not  have  revealed  all 
environmental  conditions  on  those  properties.    Discovery  of  additional  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. 

15 

 
 
 
 
 
 
 
 
 
 
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 and our reputation with our customers. 

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 10.2 billion individual semiconductor devices in 2005 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 
and reputation. 

We may fail to attract or retain the qualified technical, sales, marketing and management personnel required to operate 
our business successfully. 

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, financial condition and 
results of operations could be materially and adversely affected. 

We  may  not  be  able  to  maintain  our  growth  or  achieve  future  growth  and  such  growth  may  place  a  strain  on  our 
management and on our systems and resources. 

Our ability to successfully grow our business within the discrete and analog semiconductor markets 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. 

Our business may be adversely affected by obsolete inventories as a result of changes in  demand  for  our  products  and 
change in life cycles of our products. 

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 therefore some of our products inventory 
may become obsolete, and thus, adversely affect our results of operations. 

16 

 
 
 
 
 
 
 
 
 
 
 
 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  rely  heavily  on  our  internal  electronic  information  and  communications  systems,  and  any  system  outage  could 
adversely affect our business and results of operations. 

All  of  our  operations,  other  than  FabTech  and  Anachip,  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.    Difficulties  in 
upgrading  or  expanding  our  ERP  system  or  system-wide  or  local  failures  that  affect  our  information  processing  could  have 
material adverse effects on our business, financial condition, results of operations and cash flows. 

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 U.S. and Asian financial institutions, 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, 2005, our outstanding interest-bearing debt was $10.7 million.  
An increase of 1.0% in interest rates would increase our annual interest rate expense by approximately $107,000. 

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

Effective internal controls are necessary for us to produce reliable financial reports and are important in our effort to 
prevent financial fraud. We are required to periodically evaluate the  effectiveness  of  the  design  and  operation  of  our  internal 
controls.  These evaluations may result in the conclusion that enhancements, modifications or changes to our internal controls are 
necessary or desirable.  While management evaluates the effectiveness of our internal controls on a regular basis, these controls 
may  not  always  be  effective.    There  are  inherent  limitations  on  the  effectiveness  of  internal  controls  including  collusion, 
management override, and failure of human judgment.  Because of this, control procedures are designed to reduce rather than 
eliminate business risks. In connection with their audit of our financial statements, our independent registered public accounting 
firm identified several deficiencies in our internal controls, including a need for additional accounting personnel.  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 
and it 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 profitability. 

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 ports 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 or Kansas 
City, Missouri, 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.

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 2004 and 2005, net sales to customers 
outside the United States represented 71.3% and 74.4%, respectively, of our net sales.  There are risks inherent in doing business 
internationally, and any or all of the following factors could cause harm to our business: 

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

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

We  have  significant  operations  and  assets  in  China,  Taiwan  and  Hong  Kong  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  and  Hong  Kong.    Our  ability  to  operate  in 
China,  Taiwan  and  Hong  Kong  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 in China, Taiwan and Hong Kong are subject to the economic and political situation there.  
We  believe  that  our  operations  in  China,  Taiwan  and  Hong  Kong  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  or  Hong  Kong  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. 

 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 to some Asian currencies and, to 
a lesser extent, the Euro.  For example, many of our employees, who are located in China are paid in the Chinese Yuan and, 
accordingly, an increase in the value of the Yuan compared to the U.S. dollar could increase our operating expenses.  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 and the Hong Kong dollar.  The 
Chinese  government  has  recently  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. 

18 

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

As an incentive for establishing our first Shanghai-based manufacturing subsidiary, which we refer to as Diodes-China, 
in 1996 and in accordance with the taxation policies of China, Diodes-China, received preferential tax treatment for the years 
ended December 31, 1996 through December 31, 2005. 

Diodes-China is located in the Songjiang district, where the standard central government tax rate is 24.0%. However, as 
an  incentive  for  establishing  Diodes-China,  the  earnings  of  Diodes-China  were  subject  to  a  0% tax  rate  by  the  central 
government from 1996 through 2000, and to a 12.0% tax rate from 2001 through 2005.  For 2006 and future years, Diodes-
China’s earnings will continue to be subject to a 12.0% tax rate provided it exports at least 70.0% of its net sales.  In addition, 
due to an $18.5 million permanent re-investment of Diodes-China earnings in 2004, Diodes-China has applied to the Chinese 
government  for  additional  preferential  tax  treatment  on  earnings  that  are  generated  by  this  $18.5 million  investment.    If 
approved, those earnings will be exempted from central government income tax for two years, and then subject to a 12.0% tax 
rate for the following three years. 

In addition, the earnings of Diodes-China would ordinarily be subject to a standard local government tax rate of 3.0%.  
However,  as  an  incentive  for  establishing  Diodes-China  the  local  government  waived  this  tax  from  1996  through  2005. 
Management expects this tax to be waived for the year of 2006; however, the local government can re-impose this tax at any 
time at its discretion. 

In 2004, we established our second Shanghai-based manufacturing facility, Diodes-Shanghai, located in the Songjiang 
Export Zone of Shanghai, China.  In the Songjiang Export Zone, the central government standard tax rate is 15.0%. There is no 
local government tax.  During 2004, Diodes-Shanghai earnings were subject to the standard 15.0% central government tax rate.  
As  an  incentive  for  establishing  Diodes-Shanghai,  for  2005  and  2006  the  earnings  of  Diodes-Shanghai  are  exempted  from 
central government income tax, and for the years 2007 through 2009 its earnings will be subject to a 7.5% tax rate.  From 2010 
onward, provided that Diodes-Shanghai exports over 70% of its net sales, its earnings will be subject to a 10.0% tax rate. 

We may not be able to continue receiving this preferential tax treatment, 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. 

We are currently planning, and may in the future plan, to distribute earnings of our foreign subsidiaries from Asia to the 
United States.  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. 

On October 22, 2004, the American Jobs Creation Act, or AJCA, was signed into law.  Among other items, the AJCA 
establishes  a  phased  repeal  of  the  extraterritorial  income  exclusion,  a  new  incentive  tax  deduction  for  U.S. corporations  to 
repatriate cash from foreign subsidiaries equal to 85% of cash dividends received in the year elected that exceeds a base-period 
amount, and significantly revises the taxation of U.S. companies doing business abroad. 

At December 31, 2004, the Company made a minimum estimate for repatriating cash from its subsidiaries in China 
and Hong Kong of $8.0 million under the AJCA, and recorded an income tax expense of approximately $1.3 million. Under 
the  guidelines  of  the  AJCA,  the  Company  developed  a  required  domestic  reinvestment  plan,  covering  items  such  as  U.S. 
bank  debt  repayment,  U.S.  capital  expenditures  and  U.S.  research  and  development  activities,  among  others,  to  cover  the 
dividend repatriation.  During 2005, the Company completed a quantitative analysis of the benefits of the AJCA, the foreign 
tax  credit  implications,  and  state  and  local  tax  consequences  of  the  impact  of  the  AJCA  on  the  Company’s  plans  for 
repatriation.  Based on the analysis, the Company repatriated $24.0 million from its foreign subsidiaries in 2005. 

The  Company  is  evaluating  the  need  to  provide  additional  deferred  taxes  for  the  future  earnings  of  its  foreign 
subsidiaries  to  the  extent  such  earnings  may  be  appropriated  for  distribution  to  the  Company’s  corporate  office  in  North 
America, and as further investment strategies with respect to foreign earnings are determined.  Should the Company’s North 
American  cash  requirements  exceed  the  cash  that  is  provided  through  the  domestic  credit  facilities,  cash  can  be  obtained 
from the Company’s foreign subsidiaries.  However, the distribution of any unappropriated funds to the U.S. will require the 
recording of income tax provisions on the U.S. entity, thus reducing net income.  As of December 31, 2005, the Company 
has recorded approximately $1.1 million in deferred taxes for earnings of its foreign subsidiaries.

RISKS RELATED TO OUR COMMON STOCK 

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

We  may  experience  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:190) general economic conditions in the countries where we sell our products; 
(cid:190) seasonality and variability in the computing and communications market and our other end-markets; 
(cid:190) the timing of our and our competitors’ new product introductions; 
(cid:190) product obsolescence; 
(cid:190) the scheduling, rescheduling and cancellation of large orders by our customers; 
(cid:190) the cyclical nature of demand for our customers’ products; 
(cid:190) our ability to develop new process technologies and achieve volume production at our fabrication facilities; 
(cid:190) changes in manufacturing yields; 
(cid:190) changes in gross profit margins due to the Anachip acquisition; 
(cid:190) adverse movements in exchange rates, interest rates or tax rates; and 
(cid:190) 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 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 have no current agreements and no active negotiations underway with 
respect  to  any  acquisitions,  we  may  acquire  businesses,  products  or  technologies  in  the  future.    In  the  event  of  future 
acquisitions, we could: 

(cid:190) use a significant portion of our available cash; 
(cid:190) issue equity securities, which would dilute current stockholders’ percentage ownership; 
(cid:190) incur substantial debt; 
(cid:190) incur or assume contingent liabilities, known or unknown; 
(cid:190) incur amortization expenses related to intangibles; and 
(cid:190) 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  32%  of  our  outstanding 
Common Stock, including options to purchase shares of our Common Stock that are exercisable within 60 days of December 31, 
2005.    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  22.9%  (5,777,187  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 our non-employee Chairman of our Board of 
Directors is Chairman of the board of LSC.  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 2004 and 2005, approximately 14.7% and 17.2%, respectively, of our net sales were from products 

20 

  
  
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
  
manufactured by LSC.  In addition to being our largest external supplier of finished products in each of these periods, we sold 
silicon  wafers  to  LSC  totaling  11.1%  and  9.6%,  respectively,  of  our  net  sales  during  such  periods,  making  LSC  our  largest 
customer. 

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. 

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 1969. We have had several 
transfer agents over the past 46 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.

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

The following discussion of the Company’s financial condition and results of operations should be read together with 

the consolidated financial statements and the notes to consolidated financial statements included elsewhere in this Form 10-K. 

Overview 

We  are  a  global  supplier  of  discrete  and  analog  IC  semiconductor  products.    We  design,  manufacture  and  market 
discrete  semiconductors  focused  on  diverse  end-use  applications  in  the  consumer  electronics,  computing,  industrial, 
communications and automotive sectors.  Discrete 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 product focus provides us with a meaningful competitive advantage relative to broadline semiconductor companies that 
provide a wider range of semiconductor products. 

We are headquartered in Westlake Village, California, near Los Angeles.  We have two manufacturing facilities located 
in Shanghai, China, and a wafer fabrication facility in Kansas City, Missouri; and our sales and marketing and logistical centers 
are  located  in  Taipei,  Taiwan;  Shanghai  and  Shenzhen,  China;  and  Hong  Kong.    We  also  have  regional  sales  offices  or 
representatives in: Derbyshire, England; Toulouse, France; Frankfurt, Germany; and various cities in the United States. 

In 1998, we began to transform our business from the distribution of discrete semiconductors manufactured by others to 
the  design,  manufacture  and  marketing  of  discrete  semiconductor  products  using  our  internal  manufacturing  capabilities.  The 
key elements of our strategy of transforming our business from a distribution-based model to one primarily based on the design 
and manufacture of proprietary products are: 

(cid:190) expanding our manufacturing capacity, including establishing integrated state-of-the-art packaging and testing facilities 

in Asia, in 1998 and 2004, and acquiring a wafer foundry in the United States in 2000. 

(cid:190) expanding our sales and marketing organization in Asia in order to address the shift of manufacturing of electronics 

products from the United States to Asia. 

(cid:190) establishing our sales and marketing organization in Europe commencing in 2002. 

(cid:190) expanding the number of our field application engineers to design our products into specific end-user applications. 

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

operations: 

(cid:190) Since 1998, we have experienced increases in the demand for our products, and substantial pressure from our customers 
and competitors to reduce the selling price of our products.  We expect future increases in net income to result primarily 
from increases in sales volume and improvements in product mix in order to offset reduced average selling prices of our 
products. 

(cid:190) In 2004 and 2005, 14.3% and 15.3%, respectively, of our net sales were derived from products introduced within the 
last three years, which we term “new products,” compared to 12.1% in 2003.  New products generally have gross profit 
margins that are significantly higher than the margins of our standard products.  We expect net sales derived from new 
products  to  increase  in  absolute  terms,  although  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. 

(cid:190) Our gross profit margin was 34.6% in 2005, compared to 32.7% in 2004 and 26.7% in 2003.  This improvement in our 
gross margin was due to improvements in product mix, as well as increases in wafer and packaging yields, reductions in 
manufacturing costs and increases in capacity utilization.  We expect only modest improvements in yields and capacity 
utilization in the future and, as a result, future gross profit margins will depend primarily on our product mix, as well as 
on the demand for our product. 

(cid:190) As of December 31, 2005, we had invested approximately $95.7 million in our Asian manufacturing facilities.  During, 
2005,  we  invested  approximately  $23.5 million  in  our  Asian  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. 

25 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
(cid:190) During 2005, the percentage of our net sales derived from our Asian subsidiaries was 65.4%, compared to 59.1% in 
2004 and 55.5% in 2003.  We expect our net sales to the Asian market to continue to increase as a percentage of our 
total net sales for 2006 and beyond as a result of the continuing shift of the manufacture of electronic products from the 
United States to Asia. 

(cid:190) We have increased our investment in research and development from $3.4 million in 2004 to $3.7 million in 2005.  We 
continue  to  seek  to  hire  qualified  engineers  who  fit  our  focus  on  proprietary  discrete  processes  and  packaging 
technologies.    Our  goal  is  to  expand  research  and  development  expenses  to  approximately  2-3%  of  net  sales  as  we 
bring additional proprietary devices to the market. 

During 2005, we sold 2,125,000 shares of our Common Stock in a follow-on public offering, raising approximately 
$71.7 million (net of commissions and expenses).  We used approximately $30 million of the net proceeds in connection with 
the Anachip acquisition and we intend to use the remaining net proceeds from this offering for working capital and other general 
corporate purposes, including acquisitions. 

As  part  of  our  growth  strategy,  in  December  2005,  we  announced  the  acquisition  of  Anachip,  a  fabless  Taiwanese 
semiconductor company focused on analog ICs designed for specific applications.   The acquisition, which closed on January 10, 
2006, fits in the center of our long-term strategy.  Anachip’s main product focus is Power Management ICs. The analog devices 
they  produce  are  used  in  LCD  monitor/TV's,  wireless  LAN  802.11  access  points,  brushless  DC  motor  fans,  portable  DVD 
players, datacom devices, ADSL modems, TV/satellite set-top boxes, and power supplies.  Anachip brings a design team with 
strong  capabilities  in  a  range  of  targeted  analog  and  power  management  technologies.    This  acquisition  also  shows  our 
disciplined  approach  to  making  acquisitions.    We  paid  approximately  $30  million  to  acquire  Anachip,  which  had  power 
management IC revenues of approximately $35 million.  The acquisition is expected to be accretive to our 2006 earnings.  

Net Sales 

We generate a substantial portion of our net sales through the sale of discrete semiconductor products, designed and 
manufactured by us or third parties.  We also generate a portion of our net sales from outsourcing manufacturing capacity to 
third parties and from the sale of silicon wafers to manufacturers of discrete semiconductor components.  We serve customers 
across diversified industry segments, including the consumer electronics, computing, industrial, communications and automotive 
markets. 

We recognize revenue from product sales when title to and risk of loss of the product have passed to the customer, there 
is  persuasive  evidence  of  an  arrangement,  the  sale  price  is  fixed  or  determinable  and  collection  of  the  related  receivable  is 
reasonably assured.  These criteria are generally met upon shipment to our customers.  Net sales are stated net of reserves for 
pricing adjustments, discounts, rebates and returns. 

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

(cid:190) the condition of the economy in general and of the semiconductor industry in particular, 

(cid:190) our customers’ adjustments in their order levels, 

(cid:190) changes in our pricing policies or the pricing policies of our competitors or suppliers, 

(cid:190) the termination of key supplier relationships, 

(cid:190) the rate of introduction to, and acceptance of new products by, our customers, 

(cid:190) our ability to compete effectively with our current and future competitors, 

(cid:190) our ability to enter into and renew key corporate and strategic relationships with our customers, vendors and strategic 

alliances, 

(cid:190) changes in foreign currency exchange rates, 

(cid:190) a major disruption of our information technology infrastructure; and 

(cid:190) 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 discrete 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.  We 
expect our selling, general and administrative expenses to increase in absolute dollars as we hire additional personnel and expand 
our sales, marketing and engineering efforts and information technology infrastructure. 

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 facility in Kansas City, Missouri and our manufacturing facilities in China, as well as our 
engineers  at  our  U.S. headquarters.    All  research  and  development  expenses  are  expensed  as  incurred,  and  we  expect  our 
research and development expenses to increase in absolute dollars as we invest in new technologies and product lines. 

 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.  

 Income tax provision 

Our global presence requires us to pay income taxes in a number of jurisdictions.  In general, earnings in the United 
States  and  Taiwan  are  currently  subject  to  tax  rates  of  39.0%  and  35.0%,  respectively.  Earnings  of  Diodes-Hong  Kong  are 
currently subject to a 17.5% tax for local sales and/or local source sales, with all other sales foreign income tax-free.  Earnings at 
Diodes-Taiwan  and  Diodes-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 these earnings 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. federal  tax  liability  for  income  taxes  paid  by  our  foreign 
subsidiaries. 

As  an  incentive  for  establishing  our  first  Shanghai-based  manufacturing  subsidiary,  Diodes-China,  in  1996,  and  in 
accordance with the taxation policies of China, Diodes-China, received preferential tax treatment for the years ended December 
31, 1996 through 2005. 

Diodes-China is located in the Songjiang district, where the standard central government tax rate is 24.0%. However, as 
an  incentive  for  establishing  Diodes-China,  the  earnings  of  Diodes-China  were  subject  to  a  0%  tax  rate  by  the  central 
government from 1996 through 2000, and to a 12.0% tax rate from 2001 through 2005.  For 2006 and future years, Diodes-
China’s earnings will continue to be subject to a 12.0% tax rate provided it exports at least 70% of its net sales.  In addition, due 
to  an  $18.5  million  permanent  re-investment  of  Diodes-China  earnings  in  2004,  Diodes-China  has  applied  to  the  Chinese 
government  for  additional  preferential  tax  treatment  on  earnings  that  are  generated  by  this  $18.5  million  investment.    If 
approved, those earnings will be exempted from central government income tax for two years, and then subject to a 12.0% tax 
rate for the following three years. 

In addition, the earnings of Diodes-China would ordinarily be subject to a standard local government tax rate of 3.0%.  
However,  as  an  incentive  for  establishing  Diodes-China,  the  local  government  waived  this  tax  from  1996  through  2005.  
Management expects this tax to be waived for at least the first half of 2006, however, the local government can re-impose this 
tax at any time in its discretion.

In 2004, we established our second Shanghai-based manufacturing facility, Diodes-Shanghai, located in the Songjiang 
Export Zone of Shanghai, China.  In the Songjiang Export Zone, the central government standard tax rate is 15.0%. There is no 
local government tax.  During 2004, Diodes-Shanghai earnings were subject to the standard 15.0% central government tax rate.  
As  an  incentive  for  establishing  Diodes-Shanghai,  for  2005  and  2006  the  earnings  of  Diodes-Shanghai  are  exempted  from 
central government income tax, and for the years 2007 through 2009 its earnings will be subject to a 7.5% tax rate.  From 2010 
onward, provided that Diodes-Shanghai exports over 70% of its net sales, its earnings will be subject to a 10.0% tax rate. 

Earnings of Diodes-Taiwan are currently subject to a tax rate of 35%, which is comparable to the U.S. Federal tax rate 
for C corporations.  Earnings of Diodes-Hong Kong are currently subject to a 17.5% tax for local sales and/or local source sales, 
all other sales are foreign income tax-free. 

In accordance with United States tax law, the Company receives credit against its U.S. Federal tax liability for corporate 
taxes paid in foreign jurisdictions.  The repatriation of funds from foreign subsidiaries to the Company may be subject to Federal 
and state income taxes.   

As  of  December  31,  2005,  accumulated  and  undistributed  earnings  of  Diodes-China  and  Diodes-Shanghai  are 
approximately $51.2 million, including $28.5 million of restricted earnings (which are not available for dividends).   Through 
March 31, 2002, the Company had not recorded deferred U.S. Federal or state tax liabilities (estimated to be $8.9 million as of 
March 31, 2002) on these cumulative earnings since the Company, at that time, considered this investment to be permanent, and 
had no plans or obligation to distribute all or part of that amount from China to the United States.  Beginning in April 2002, the 
Company began to record deferred taxes on a portion of the China earnings in preparation of a dividend distribution.  In the year 
ended December 31, 2004, the Company received a dividend of approximately $5.7 million from its Diodes-China subsidiary, 
for which the tax effect is included in U.S. Federal and state taxable income. 

On  October  22,  2004,  the  President  of  the  United  States  signed  the  American  Jobs  Creation  Act  (AJCA)  into  law.  
Originally intended to repeal the extraterritorial income (ETI) exclusion, which had triggered tariffs by the European Union, the 
AJCA expanded to cover a wide range of business tax issues.  Among other items, the AJCA establishes a phased repeal of the 
ETI,  a  new  incentive  tax  deduction  for  U.S.  corporations  to  repatriate  cash  from  foreign  subsidiaries  at  a  reduced  tax  rate  (a 
deduction  equal  to  85%  of  cash  dividends  received  in  the  year  elected  that  exceeds  a  base-period  amount)  and  significantly 
revises the taxation of U.S. companies doing business abroad. 

At December 31, 2004, the Company made a minimum estimate for repatriating cash from its subsidiaries in China and 
Hong Kong of $8.0 million under the AJCA, and recorded an income tax expense of approximately $1.3 million.  Under the 
guidelines of the AJCA, the Company developed a required domestic reinvestment plan, covering items such as U.S. bank debt 
repayment,  U.S.  capital  expenditures  and  U.S.  research  and  development  activities,  among  others,  to  cover  the  dividend 
repatriation.  During 2005, the Company completed a quantitative analysis of the benefits of the AJCA, the foreign tax credit 
implications, and state and local tax consequences of the impact of the AJCA on the Company’s plans for repatriation.  Based on 
the analysis, the Company repatriated $24.0 million from its foreign subsidiaries in 2005. 

The  Company  is  evaluating  the  need  to  provide  additional  deferred  taxes  for  the  future  earnings  of  its  foreign 
subsidiaries  to  the  extent  such  earnings  may  be  appropriated  for  distribution  to  the  Company’s  corporate  office  in  North 
America,  and  as  further  investment  strategies  with  respect to  foreign  earnings  are  determined.    Should  the  Company’s  North 
American cash requirements exceed the cash that is provided through the domestic credit facilities, cash can be obtained from the 
Company’s foreign subsidiaries.  However, the distribution of any unappropriated funds to the U.S. will require the recording of 
income  tax  provisions  on  the  U.S.  entity,  thus  reducing  net  income.    As  of  December  31,  2005,  the  Company  has  recorded 
approximately $1.1 million in deferred taxes for earnings of its foreign subsidiaries, primarily Diodes-Hong Kong.

CRITICAL ACCOUNTING POLICIES 

The  preparation  of  financial  statements  in  accordance  with  GAAP  requires  management  to  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,  including  those  related  to  revenue  recognition,  allowance  for  doubtful  accounts,  inventory 
reserves  and  income  taxes,  among  others.    Our  estimates  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  and  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 

We recognize revenue when there is persuasive evidence that an arrangement exists, when delivery has occurred, when 
our price to the buyer is fixed or determinable and when collectibility of the receivable is reasonably assured. These elements are 
met when title to the products is passed to the buyers, which is generally when our product is shipped. 

We  reduce  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 North American 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. 

 Inventory reserves 

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 material, 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.    Based  upon  this  analysis,  as  well  as  an  inventory  aging  analysis,  we  accrue  a 
reserve for obsolete and slow-moving inventory.  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.  Significant management judgment is required in determining our provision for income taxes, deferred tax assets and 
liabilities.  Management continually evaluates its deferred tax asset as to whether it is likely that the deferred tax assets will be 
realized.    If  management  ever  determined  that  our  deferred  tax asset  was  not  likely  to  be  realized,  a  write-down  of  the  asset 
would be required and would be reflected as an expense in the accompanying period. 

Allowance for doubtful accounts 

Management evaluates 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. 

Impairment of long-lived assets 

As of December 31, 2005, goodwill was $5.1 million ($4.2 million related to the FabTech acquisition, and $881,000 
related  to  Diodes-China).    We  account  for  goodwill  in  accordance  with  SFAS No. 142  (“Goodwill  and  Other  Intangible 

29 

 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Assets”), for which goodwill is tested for impairment at least annually.  We performed the required impairment tests of goodwill 
and have determined that the goodwill is fully recoverable. 

We  assess  the  impairment  of  long-lived  assets,  including  goodwill,  on  an  on-going  basis  and  whenever  events  or 
changes in circumstances indicate that the carrying value may not be recoverable.  Our impairment review process is based upon 
(i) an income approach from a discounted cash flow analysis, which uses our estimates of revenues, costs and expenses, as well 
as market growth rates, and (ii) a market multiples approach which measures the value of an asset through an analysis of recent 
sales or offerings or comparable public entities.  If ever the carrying value of the goodwill is determined to be less than the fair 
value of the underlying asset, a write-down of the asset will be required, with the resulting expense charged in the period that the 
impairment was determined.

The  following  discussion  explains  in  greater  detail  the  consolidated  financial  condition  of  the  Company.    This 
discussion should be read in conjunction with the consolidated financial statements and notes thereto appearing elsewhere 
herein.  Earnings per share discussion reflects the three-for-two stock split in December 2005.  All per share amounts have 
been adjusted to reflect the stock split. 

Year 2005 Compared to Year 2004 

Net sales  

Net sales for 2005 increased $29.1 million to $214.8 million from $185.7 million for 2004.  The 15.6% increase was 
due  primarily  to  an  approximately  36.0%  increase  in  units  sold  as  a  result  of  increased  end-market  demand  for  the 
Company’s products, partly offset by a 15.0% decrease in total average selling prices (ASPs).  ASPs for discrete products 
decreased by 10.7% while ASPs for wafers fell 17.3%.  The following table sets forth the geographic breakdown of our net 
sales for the periods indicated based on the country to which the product is shipped:

Cost of goods sold  

Cost of goods sold increased $15.4 million, or 12.3%, for 2005 compared to $125.0 million in 2004.  As a percent 
of sales, cost of goods sold decreased from 67.3% for 2004 to 65.4% for 2005.  The Company’s average unit cost (AUP) for 
discrete devices decreased approximately 14.3% from 2004, and AUPs for wafer products decreased approximately 14.9%.  
These cost decreases were due primarily to improved manufacturing efficiencies. 

Gross profit  

Gross profit for 2005 increased 22.5% to $74.4 million from $60.7 million for 2004.  Of the $13.7 million increase, 
$9.6 million was due to the 190 basis point increase in gross profit margin from 32.7% in 2004 to 34.6% in 2005, while $4.1 
million was due to the 22.5% increase in net sales.  Gross profit increases in Asia were the primary contributor to the gross 
profit  increase  in  2005.    The  higher  gross  margin  percentage  was  due  primarily  to  improved  product  sales  mix,  increased 
capacity utilization and manufacturing efficiencies, partially offset by pricing pressure on our wafer products. 

Selling, general and administrative expenses 

Selling,  general  and  administrative  expenses  (SG&A)  for  2005  increased  approximately  $6.8 million,  or  28.9%, 
compared  to  $23.5  million  2004,  due  primarily  to  (i) a  $1.8  million  expense  relating  to  share  inducement  grants  made  to 
Dr. Keh-Shew  Lu,  our  President  and  Chief  Executive  Officer,  and  C.H.  Chen,  our  Vice  Chairman,  (ii)  higher  sales 
commissions, wages and marketing expenses associated with increased sales and, (iii) consulting, legal and accounting fees 
primarily associated with Sarbanes-Oxley compliance.  SG&A, as a percentage of net sales, was 14.1% in 2005, compared to 
12.7% in 2004.

Research and development expenses 

Research  and  development  expenses  (R&D)  increased  to  $3.7  million,  or  1.7%  of  net  sales,  in  2005  from  $3.4 
million, or 1.8% of net sales, in 2004.  R&D expenses are primarily related to new product development at the silicon wafer 
level, and, to a lesser extent, at the packaging level.  We continue to seek to hire qualified engineers who fit our focus on 
next-generation  processes  and  packaging  technologies.    Our  goal  is  to  expand  R&D  to  2-3%  of  revenue  as  we  bring 
proprietary technology and advanced devices to the market. 

Gain on sale of fixed assets 

Gain  on  sale  of  fixed  assets  of  $102,000  for  2005  was  due  primarily  to  a  gain  on  the  termination  of  two  capital 

leases in China. 

Interest income / expense 

Net interest income for 2005 was $221,000 compared to net interest expense of $620,000 in 2004, due primarily to 
interest income earned on proceeds from our public offering of equity securities in 2005, as well as to a reduction in our total 
debt from $17.5 million at December 31, 2004 to $12.5 million at December 31, 2005.  Our interest income is generated for 
interest  earned  on  our  cash  balances  and  short-term  investments.    Our  interest  expense  has  been  primarily  the  result  of 
borrowings to finance the FabTech acquisition in 2000, as well as our ongoing investment in, and expansion of, our Diodes-
China and Diodes-Shanghai manufacturing facilities. 

Other income 

Other income for 2005 increased $824,000 from 2004, due primarily to lower currency exchange losses in Taiwan 

as well as the expiration of management incentive agreements associated with the FabTech acquisition. 

Income tax provision 

We  recognized  income  tax  expense  of  $6.7 million  for  2005,  resulting  in  an  effective  tax  rate  of  16.3%,  as 
compared to $6.5 million or 19.9% for the same period in 2004, due primarily to an increase in profits earned in lower tax 
rate jurisdictions.  

Minority interest in joint venture earnings 

Minority interest in joint venture earnings represents the minority investor’s share of the income of Diodes-China 
and Diodes-Shanghai. We established Diodes-Shanghai in 2004. The increase in these subsidiaries’ income for the tweleve 
months ended December 31, 2005 is primarily the result of increased sales, and manufacturing efficiencies. As of December 
31, 2005, we had a 95% controlling interest in each of these subsidiaries. 

Net income 

We generated net income of $33.3 million (or $1.44 basic earnings per share and $1.29 diluted earnings per share) 
for the twelve months ended December 31, 2005, as compared to $25.6 million (or $1.27 basic earnings per share and $1.10 
diluted earnings per share) for the same period in 2004. This 30.4% increase in net income is due primarily to the 15.6% net 
sales increase at a gross profit margin of 34.6% for 2005, compared to a gross profit margin of 32.7% in 2004.

Year 2004 Compared to Year 2003 

Net sales  

Net sales for 2004 increased $48.8 million to $185.7 million, from $136.9 million for 2003. The 35.6% increase was 
due primarily to an approximately 40.0% increase in units sold as a result of increased demand for our products, as well as an 
improved product mix, offset in part by a 9.1% decrease in average selling prices for wafers.  The following table sets forth 
the geographic breakdown of our net sales for the periods indicated based on the country to which the product is shipped:

Cost of goods sold 

Cost of goods sold increased $24.6 million, or 24.5%, for 2004 compared to $100.3 million in 2003, as a result of 
the increase in net sales.  As a percent of net sales, however, cost of goods sold decreased to 67.3% for 2004 from 73.3% for 
2003.  Our average unit cost for discrete devices decreased approximately 6.5% from 2003, and average unit cost for wafer 
products decreased approximately 12.1%.  These cost decreases were due primarily to improved manufacturing efficiencies. 

Gross profit 

Gross profit for 2004 increased 66.3% to $60.7 million from $36.5 million for 2003. Of the $24.2 million increase, 
$13.0 million was due to an increase in gross profit margin from 26.7% in 2003 to 32.7% in 2004, while $11.2 million was 
due to the 35.6% increase in net sales.  Gross profit increases in Asia were the primary contributor to the overall gross profit 
increase in 2004.  Gross profit margin increased due to enhanced capacity utilization, continuing manufacturing efficiencies, 
relatively stable pricing, and a product mix that continued to shift toward higher-value performance discrete semiconductor 
devices. 

 Selling, general and administrative expenses 

For  2004,  SG&A  increased  $3.9 million  to  $23.5 million  from  $19.6 million  for  2003.    The  19.9%  increase  in 
SG&A was due primarily to higher sales commissions, incentives, marketing and royalty expenses associated with the 35.6% 
increase in net sales for the year, and higher wage and benefits expenses.  Also contributing to the increased selling, general 
and  administrative  expenses  were  higher  corporate  and  administrative  expenses,  including  legal  and  accounting  fees, 
primarily  associated  with  Sarbanes-Oxley  Act  compliance.    However,  as  a  percentage  of  sales,  selling,  general  and 
administrative expenses decreased to 12.7% for 2004 from 14.3% in 2003. 

 Research and development expenses 

R&D increased to $3.4 million, or 1.8% of net sales, in 2004 from $2.0 million, or 1.5% of sales, in 2003. R&D was 

primarily related to new product development relating to silicon wafers, and, to a lesser extent, packaging.

Interest expense, net 

 Net interest expense for 2004 decreased $223,000 to $637,000 from $860,000 in 2003, due primarily to a decrease 
in the use of our credit facilities, as well as to lower interest rates. In 2004, we repaid $3.6 million of debt outstanding under 
our  credit  facilities,  reducing  the  balances  outstanding  from  $21.1 million  at  December 31,  2003  to  $17.5 million  at 
December 31, 2004. 

 Other expense 

Other  expense  for  2004  increased  $413,000  compared  to  2003,  primarily  due  to  approximately  $400,000  in 
currency  exchange  losses  related  to  the  weakened  U.S.  dollar,  primarily  versus  the  Taiwan  dollar,  recorded  in  the  fourth 
quarter of 2004. 

 Income tax provision 

 Our effective tax rate in 2004 was 19.9%, compared to 18.9% for 2003.  We recorded a provision for income taxes 
in  the  amount  of  $6.5 million  for  2004,  compared  to  $2.5 million  for  2003.    Included  in  the  tax  provision  for  2004  is 
$1.3 million in deferred taxes recorded in the fourth quarter for an $8.0 million planned dividend distribution from our Asian 
subsidiaries  in  2005  under  the  AJCA,  offset  by  a  $1.2 million  foreign  investment  tax  refund  (net  of  U.S.  taxes),  and  an 
approximately $500,000 research and development tax credit. 

Minority interest in joint venture earnings 

 The minority interest in joint venture earnings represents the minority investor’s share of income of Diodes-China 
and  Diodes-Shanghai.  Diodes-Shanghai  was  established  in  2004.    The  increase  in  these  subsidiaries’  income  for  2004  is 
primarily  the  result  of  increased  sales  of  higher  margin  products.    As  of  December 31,  2004,  we  had  a  95%  controlling 
interest in each of these subsidiaries. 

 Net income 

 We generated net income of $25.6 million (or $1.27 basic earnings per share and $1.10 diluted earnings per share) 
in  2004,  as  compared  to  $10.1 million  (or  $0.53  basic  earnings  per  share  and  $0.47  diluted  earnings  per  share)  for  2003.  
This  153.5%  increase  in  net  income  is  due  primarily  to  the  35.6%  net  sales  increase  at  a  gross  profit  margin  of  32.7%  in 
2004, compared to a gross profit margin of 26.7% in 2003. 

Financial Condition 

Liquidity and Capital Resources 

Our  primary  sources  of  liquidity  are  cash,  funds  from  operations  and  borrowings  under  our  credit  facilities.  Our 
primary liquidity requirements have been to meet our inventory and capital expenditure needs.  For 2003, 2004 and 2005, our 
working capital was $27.2 million, $49.6 million, and $146.7 million, respectively.  We anticipate our working capital position 
will be sufficient for at least the next 12 months. 

In  2003,  2004  and  2005,  our  capital  expenditures  were  $17.0 million,  $26.5 million  and  $24.7 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 United States.  The increased amount of capital expenditures from 2003 to 2004 
($17.0 million and $26.5 million, respectively) was primarily attributable to increasing capacity at our facilities to meet demand 
for our products, including the establishment of our Diodes-Shanghai facility in 2004.  In 2005, our capital expenditures reduced 
to $24.6 million as a result of increased equipment efficiencies and the slower market growth as compared to 2004. 

Discussion of cash flows 

Cash  and  short-term  investments  have  increased  from  $12.8 million  at  December 31,  2003,  to  $19.0 million  at 
December 31,  2004,  to  $113.6 million  at  December 31,  2005.    The  increase  from  2004  to  2005  was  primarily  due  to  the 
proceeds from the follow-on offering.

Operating activities 

Net cash provided by operating activities during 2005 was $50.6 million, resulting primarily from $33.3 million of net 
income in this period.  Net cash provided by operating activities was $29.3 million for 2004 and $18.8 million for 2003. Net cash 
provided  by  operations  increased  by  $21.3 million  from  2004  to  2005.    This  increase  resulted  primarily  from  a  $7.8 million 
increase in our net income (from $25.6 million in 2004 to $33.3 million in 2005) and decreases in inventories, resulting from 
faster  inventory  turns,  and  decreases  in  accounts  receivable.    We  continue  to  closely  monitor  our  credit  terms  with  our 
customers, while at times providing extended terms, primarily required by our customers in Asia and Europe. 

Investing activities 

Net cash used by investing activities for 2005 was $65.8 million resulting from capital expenditures of $19.6 million 
(net of $5.1 million purchased on accounts payable), short-term investments of municipal bonds and equity investments.  Net 
cash used by investing activities was $26.1 million for 2004 and $15.6 million for 2003.  Net cash used for investing activities in 
those periods primarily related to manufacturing expansion in our facilities in China and, to a lesser extent, our wafer fabrication 
facility in the United States. 

 Financing activities 

Net  cash  provided  by  financing  activities  for  2005  was  $70.8 million,  resulting  primarily  from  $71.7 million  in  net 
proceeds from the offering of equity securities, offset by $10.9 million debt repayment.  In addition, the Company received $4.2 
million  from  stock  option  exercises  in  2005.    Net  cash  provided  by  financing  activities  was  $2.2 million  for  2004  and 
$1.9 million  for  2003.    Net  cash  provided  by  financing  activities  for  2004  was  primarily  due  to  $5.6  million  received  in 
connection  with  the  exercise  of  stock  options,  partially  offset  by  $4.8 million  repaid  under  our  debt  instruments.    Net  cash 
provided by financing activities for 2003 was primarily due to $2.0 million received in connection with  the  exercise  of  stock 
options. 

Debt instruments 

On August 29, 2005, we amended our U.S. credit arrangements with Union Bank of California, N.A. (Union Bank). 
Under  the  second  amendment  to  our  amended  and  restated  credit  agreement,  we  now  have  available  a  revolving  credit 
commitment of up to $20.0 million, including a $5.0 million letter of credit sub-facility.  In addition, and in connection with this 
amendment, one of our subsidiaries, FabTech, also amended and restated a term note and related agreement with respect to an 
existing term loan arrangement, which we refer to as the FabTech term loan.  After giving effect to this amendment, the principal 
amount under the FabTech term loan was increased to $5.0 million. 

The  revolving  credit  commitment  expires  on  August 29,  2008.    The  FabTech  term  loan,  which  amortizes  monthly, 
matures on August 29, 2010.  As of December 31, 2005, we had no amounts outstanding under our revolving credit facility, and 
there  was  $4.7 million  outstanding  under  the  FabTech  term  loan.    Loans  to  Diodes  Incorporated  under  our  credit  facility  are 
guaranteed by FabTech, and in turn, the FabTech term loan is guaranteed by Diodes Incorporated.  The purpose of the revolving 
credit facility is to provide cash for domestic working capital purposes, and to fund permitted acquisitions. 

All  loans  under  the  credit  facility  and  the  FabTech  term  loan  are  collateralized  by  all  of  Diodes  Incorporated’s  and 
FabTech’s  accounts,  instruments,  chattel  paper,  documents,  general  intangibles,  inventory,  equipment,  furniture  and  fixtures, 
pursuant to security agreements entered into by Diodes Incorporated and FabTech in connection with these credit arrangements. 

Both  amounts  borrowed  under  the  revolving  credit  facility  and  the  FabTech  term  loan  bear  interest  at  LIBOR  plus 
1.15%.  At December 31, 2005, the effective rate under both the credit agreement and the FabTech term loan was LIBOR plus 
1.15%, or 5.38%. 

The credit agreement contains covenants that require us to maintain a leverage ratio not greater than 2.25  to  1.0,  an 
interest expense coverage ratio of not less than 2.0 to 1.0 and a current ratio of not less than 1.0 to 1.0.  It also requires us to 
achieve a net profit before taxes, as of the last day of each fiscal quarter, for the two consecutive fiscal quarters ending on that 
date  of  not  less  than  $1.    The  credit  agreement  permits  us  to  pay  dividends  to  our  stockholders  to  the  extent  that  any  such 
dividends declared or paid in any fiscal year do not exceed an amount equal to 50% of our net profit after taxes for such fiscal 
year.    However,  it  limits  our  ability  to  dispose  of  assets,  incur  additional  indebtedness,  engage  in  liquidation  or  merger, 
acquisition,  partnership  or  other  combination  (except  permitted  acquisitions).    The  credit  agreement  also  contains  customary 
representations, warranties, affirmative and negative covenants and events of default.

The agreements governing the FabTech term loan do not contain any financial or negative covenants. However, they 

provide that a default under our credit agreement will cause a cross-default under the FabTech term loan. 

As of December 31, 2005, FabTech had paid down $3.75 million, to pay in full a note in favor of LSC, which debt was 
incurred in connection with our acquisition of FabTech from LSC in 2000. This note matured on June 30, 2006 and amortized 
monthly. The obligations under this note were subordinated to the obligations under our U.S. credit agreement with Union Bank. 

Diodes-China and Diodes-Taiwan have available lines of credit of up to an aggregate of $29.2 million, with a number 
of Chinese and Taiwanese financial institutions. These lines of credit, except for one Taiwanese credit facility, are collateralized 
by its 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. 

As  of  December 31,  2005,  Diodes-China  owed  $1.8 million  under  a  note  to  one  of  our  customers,  which  debt  was 
incurred  in  connection  with  our  investing  in  manufacturing  equipment.  We  repay  this  unsecured  and  interest-free  note  in 
quarterly price concession installments, with any remaining balance due in July 2008. 

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  (except  for  the  interest  rate  swap  agreement,  which  expired  in 
November 30, 2004), or research and development services, that could expose us to liability that is not reflected on the face of 
our financial statements.

There  have  been  no  material  changes  to  our  contractual  obligations  as  of  December 31,  2005,  as  compared  to 
December 31, 2004.  Inflation did not have a material effect on net sales or net income in fiscal years 2003 through 2005.  A 
significant increase in inflation could affect future performance. 

Recently Issued Accounting Pronouncements and Proposed Accounting Changes 

In May 2005, the Financial Accounting Standards Board (FASB) issued SFAS No. 154, “Accounting Changes and 
Error  Corrections,  A  Replacement  of  APB  Opinion  No.  20  and  FASB  Statement  No.  3.”  SFAS  154  requires  retrospective 
application to prior periods’ financial statements for changes in accounting principles, unless it is impracticable to determine 
either the period-specific effects or the cumulative effect of the change. SFAS 154 also requires that retrospective application 
of a change in accounting principle be limited to the direct effects of the change. Indirect effects of a change in accounting 
principle,  such  as  a  change  in  non-discretionary  profit-sharing  payments  resulting  from  an  accounting  change,  should  be 
recognized in the period of the accounting change. SFAS 154 also requires that a change in depreciation, amortization, or 
depletion  method  for  long-lived,  non-financial  assets  be  accounted  for  as  a  change  in  accounting  estimate  effected  by  a 
change in accounting principle. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years 
beginning after December 15, 2005. Early adoption is permitted for accounting changes and corrections of errors made in 
fiscal years beginning after the date this Statement is issued. The Company does not anticipate a material impact on the financial 
statements from the adoption of this consensus. 

In March 2005, the FASB issued FASB Interpretation (FIN) No. 47, “Accounting for Conditional Asset Retirement 
Obligations, An Interpretation of FASB Statement No. 143,” which requires an entity to recognize a liability for the fair value 
of  a  conditional  asset  retirement  obligation  when  incurred  if  the  liability’s  fair  value  can  be  reasonably  estimated.  The 

36 

  
 
  
 
  
 
  
  
  
 
 
 
 
 
 
 
 
 
adoption of this Interpretation did not have a material impact on the Company’s consolidated financial position, results of 
operations or cash flows. 

In December 2004, FASB issued SFAS No. 123(R). This new standard requires companies to adopt the fair value 
methodology of valuing stock-based compensation and recognizing that valuation in the financial statements from the date of 
grant.  Accordingly, the adoption of SFAS No. 123(R)’s fair value method will have a significant impact on our results of 
operations, although it will have no impact on our overall financial position.  The impact of adoption of SFAS No. 123(R) 
cannot  be  predicted  at  this  time  because  it  will  partially  depend  on  levels  of  share-based  payments  granted  in  the  future.  
However,  had  we  adopted  SFAS No. 123(R)  in  prior  periods,  the  impact  of  that  standard  would  have  approximated  the 
impact of SFAS No. 123 as shown in the Stock-based Compensation table contained in Note 1 of our financial statements.  
SFAS No. 123(R) also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a 
financing cash flow, rather than as an operating cash flow as required under current literature.  We are currently evaluating 
several  option  valuation  models  in  order  to  calculate  the  required  compensation  expense.    We  have  elected  to  adopt  the 
provisions  of  SFAS No. 123(R)  on  a  modified  prospective  application  method  with  no  restatement  of  any  prior  periods. 
SFAS No. 123(R) is effective for us as of the beginning of the fiscal year ending December 31, 2006. 

In December 2004, the FASB also issued SFAS No. 151, “Inventory Costs, an amendment of ARB No. 43, Chapter 
4.”  This standard clarifies that abnormal amounts of idle facility expense, freight, handling costs and wasted material should 
be  expensed  as  incurred  and  not  included  in  overhead.  In  addition,  this  standard  requires  that  the  allocation  of  fixed 
production overhead costs to inventory be based on the normal capacity of the production facilities. The provisions of this 
standard are effective for the fiscal years beginning after June 15, 2005. The Company is currently evaluating the potential 
impact of this standard on its financial position and results of operations, but does not believe the impact of the change will 
be material. 

On October 22, 2004, the American Jobs Creation Act of 2004 was passed, which raised a number of issues with 
respect to accounting for income taxes. In response, on December 21, 2004, the FASB issued two FASB Staff Positions, or 
FSP,  FSP  109-1—  Application  of  FASB  Statement  No. 109,  Accounting  for  Income  Taxes,  to  the  Tax  Deduction  on 
Qualified  Production  Activities  Provided  by  the  American  Jobs  Creation  Act  of  2004  and  FSP  109-2—  Accounting  and 
Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of 2004, which 
became effective for us upon issuance. 

The  AJCA  provides  a  deduction  for  income  from  qualified  domestic  production  activities,  to  be  phased  in  from 
2005 through 2010, which is intended to replace the existing extra-territorial income exclusion for foreign sales.  In FSP 109-
1,  the  FASB  decided  the  deduction  for  qualified  domestic  production  activities  should  be  accounted  for  as  a  special 
deduction under SFAS No. 109, rather than as a rate reduction.  Accordingly, any benefit from the deduction will be reported 
in  the  period  in  which  the  deduction  is  claimed  on  the  tax  return.    No  adjustment  to  deferred  taxes  was  required.    The 
adoption of this standard is not expected to have significant impact on Company’s consolidated financial statements.   

The AJCA also creates a temporary incentive for U.S. corporations to repatriate accumulated income earned abroad 
by  providing  an  85.0%  dividends  received  deduction  for  certain  dividends  from  controlled  foreign  corporations.    The 
deduction  is  subject  to  a  number  of  limitations  and  uncertainty  remains  as  to  how  to  interpret  numerous  provisions  in  the 
AJCA.    FSP  109-2  addresses  when  to  reflect  in  the  financial  statements  the  effects  of  the  one-time  tax  benefit  on  the 
repatriation of foreign earnings.  Under SFAS No. 109, companies are normally required to reflect the effect of new tax law 
changes in the period of enactment.  FSP 109-2 provides companies additional time to determine the amount of earnings, if 
any, that they intend to repatriate under the AJCA’s provisions.  See Note 8 of our financial statements for more discussion 
of the impact of the AJCA, including the impact on our repatriation of foreign earnings. 

In  November  2004,  the  Emerging  Issues  Task  Force,  or  EITF,  reached  a  consensus  on  EITF  Issue  No. 03-13, 
Applying the Conditions in Paragraph 42 of FASB Statement No. 144, Accounting for the Impairment or Disposal of Long-
Lived Assets, in Determining Whether to Report Discontinued Operations. The consensus provides guidance in determining: 
(1) which cash flows should be taken into consideration when assessing whether the cash flows of the disposal component 
have been or will be eliminated from the ongoing operations of the entity, (2) the types of involvement ongoing between the 
disposal component and the entity disposing of the component that constitute continuing involvement in the operations of the 
disposal  component,  and  (3) the  appropriate  (re)assessment  period  for  purposes  of  assessing  whether  the  criteria  in 
paragraph 42 have been met. The consensus was ratified by the FASB at their November 30, 2004 meeting and should be 
applied to a component of an enterprise that is either disposed of or classified as held for sale in fiscal periods beginning after 
December 15, 2004. We do not anticipate a material impact on our financial statements from the adoption of this consensus. 

In September 2004, the EITF reached a consensus on EITF Issue No. 04-10, Applying Paragraph 19 of FAS 131 in 
determining whether to aggregate operating segments that do not meet the quantitative thresholds. The consensus states that 

37 

 
 
 
 
 
 
 
operating segments that do not meet the quantitative thresholds can be aggregated only if aggregation is consistent with the 
objective and basic principles of SFAS No. 131, “Disclosures  about  Segments  of  an  Enterprise  and  Related  Information,” 
the  segments  have  similar  economic  characteristics,  and  the  segments  share  a  majority  of  the  aggregation  criteria  (a)-(e) 
listed  in  paragraph 17  of  SFAS No. 131.  The  effective  date  of  the  consensus  in  this  Issue  is  for  fiscal  years  ending  after 
October 13, 2004. The ratification of this Issue did not have an impact on our financial reporting. 

In  March  2004,  the  EITF  reached  a  consensus  on  the  remaining  portions  of  EITF 03-01,  The  Meaning  of  Other-
Than-Temporary Impairment and Its Application to Certain Investments with an effective date of June 15, 2004. EITF 03-01 
provides new disclosure requirements  for other-than-temporary impairments on debt and equity investments. Investors  are 
required  to  disclose  quantitative  information  about:  (1) the  aggregate  amount  of  unrealized  losses,  and  (2) the  aggregate 
related fair values of investments with unrealized losses, segregated into time periods during which the investment has been 
in  an  unrealized  loss  position  of  less  than  12 months  and  greater  than  12 months.  In  addition,  investors  are  required  to 
disclose the qualitative information that supports their conclusion that the impairments noted in the qualitative disclosure are 
not other-than temporary. We determined that EITF 03-01 would not have a material impact on our financial statements. 

In December 2003, the FASB issued FASB Interpretation No. 46R, or FIN 46R, Consolidation of Variable Interest 
Entities, a revision to Interpretation No. 46. FIN 46R clarifies the application of consolidation accounting for certain entities 
that  do  not  have  sufficient  equity  at  risk  for  the  entity  to  finance  its  activities  without  additional  subordinated  financial 
support from other parties or in which equity investors do not have the characteristics of a controlling financial interest; these 
entities are referred to as “variable interest entities.” Variable interest entities within the scope of FIN 46R are required to be 
consolidated by their primary beneficiary. The primary beneficiary of a variable interest entity is determined to be the party 
that  absorbs  a  majority  of  the  entity’s  expected  losses,  receives  a  majority  of  its  expected  returns,  or  both.  FIN 46R  also 
requires  disclosure  of  significant  variable  interests  in  variable  interest  entities  for  which  a  company  is  not  the  primary 
beneficiary.  We have assessed Diodes-Shanghai under the provisions of FIN 46R and have concluded that our investment in 
Diodes-Shanghai does not meet the criteria for consolidation under the standard.  However, Diodes-Shanghai is consolidated 
under other applicable accounting literature.  We will periodically review our investment in Diodes-Shanghai to insure that 
we comply with the guidelines prescribed by FIN 46R. 

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. 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.  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 and the Taiwanese dollar and, to a lesser extent, the Japanese Yen, the 
Euro and the Hong Kong dollar.  Because of the relatively small size and nature of each individual currency exposure, we do 
not regularly employ hedging techniques designed to mitigate foreign currency exposures.  Therefore, we could experience 
currency gains and losses.  If the Chinese Yuan and the Taiwanese dollar were to strengthen or weaken by 1.0% against the 
U.S. dollar,  we  would  experience  currency  gains  or  losses  of  approximately  $150,000  and  $60,000,  respectively.    In  the 
future, we may enter into hedging arrangements designed to mitigate foreign currency fluctuations. 

 In July 2005, the Chinese government allowed the Chinese Yuan to float and be traded freely, although it is only 
permitted  to  float  within  a  0.3%  band  against  the  Chinese  central  bank  rate  set  for  the  U.S. dollar.    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 an adverse impact upon our financial results. 

Interest  Rate  Risk.    We  have  credit  facilities  with  U.S.  and  Asian  financial  institutions  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.  In July 2001, we entered into an interest rate 
swap agreement to hedge our exposure to variability in expected future cash flows resulting from interest rate risk related to 
a portion of our long-term debt.  The interest rate under the swap agreement was fixed at 6.8% and was based on the notional 
amount  of  U.S. $2.3 million  as  of  December 31,  2003.    The  swap  contract  was  inversely  correlated  to  the  related  hedged 
long-term debt and was therefore considered an effective cash flow hedge of the underlying long-term debt.  The level of 
effectiveness  of  the  hedge  was  measured  by  the  changes  in  the  market  value  of  the  hedged  long-term  debt  resulting  from 
fluctuation in interest rates.  At November 30, 2004 the interest rate swap agreement on our long-term debt expired.  As a 
matter of policy, we do not enter into derivative transactions for trading or speculative purposes.  As of December 31, 2005, 
our outstanding debt under our interest-bearing credit agreements was $10.7 million.  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 $107,000.

Disclosure Controls and Procedures 

The  Company's  Chief  Executive  Officer,  Dr. Keh-Shew  Lu,  and  Chief  Financial  Officer,  Carl  C.  Wertz,  with  the 
participation  of  the  Company's  management,  carried  out  an  evaluation  of  the  effectiveness  of  the  Company's  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,  the  Company's  disclosure 
controls  and  procedures  are  effective  to  provide  reasonable  assurance  that  material  information  relating  to  the  Company 
(including its consolidated subsidiaries) required to be included in this report is made known to them. 

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, 2005.

Management's assessment of the effectiveness of our internal control over financial reporting as of December 31, 2005 has 
been  audited  by  Moss  Adams  LLP,  an  independent  registered  public  accounting  firm,  who  has  expressed  unqualified 
opinions on management's assessment and on the effectiveness of the Company's internal control over financial reporting as 
of December 31, 2005 as stated in their report which is included in Item 8 of this Report. 
Changes in Internal Control 

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

Report of Independent Registered Public Accounting Firm 

Board of Directors and Stockholders 
Diodes Incorporated and Subsidiaries 

We  have  audited  management's  assessment,  included  in  the  accompanying  Management's  Report  on  Internal 
Control  over  Financial  Reporting  that  Diodes  Incorporated  and  Subsidiaries  maintained  effective  internal  control  over 
financial reporting as of December 31, 2005, based on criteria set forth by the Committee of Sponsoring Organizations of the 
Treadway  Commission  (COSO)  in  Internal  Control  -  Integrated  Framework.    Diodes  Incorporated  and  Subsidiaries’ 
management is responsible  for  maintaining  effective  internal  control  over  financial  reporting  and  for  its  assessment  of  the 
effectiveness  of  internal  control  over  financial  reporting.  Our  responsibility  is  to  express  an  opinion  on  management's 
assessment and an opinion on the effectiveness of the company's internal control over financial reporting based on our audit. 

We  conducted  our  audit  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United  States).  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about  whether 
effective  internal  control  over  financial  reporting  was  maintained  in  all  material  respects.  Our  audit  included  obtaining  an 
understanding  of  internal  control  over  financial  reporting,  evaluating  management's  assessment,  testing  and  evaluating  the 
design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in 
the circumstances. We believe that our audit provides a reasonable basis for our opinion. 

A  company's  internal  control  over  financial  reporting  is  a  process  designed  to  provide  reasonable  assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance 
with accounting principles generally accepted in the United States of America.  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 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,  management's  assessment  that  Diodes  Incorporated  and  Subsidiaries  maintained  effective  internal 
control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based on criteria set forth 
by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO)  in  Internal  Control  -  Integrated 
Framework.  Also in our opinion, Diodes Incorporated and Subsidiaries maintained, in all material respects, effective internal 
control  over  financial  reporting  as  of  December  31,  2004,  based  on  criteria  set  forth  by  the  Committee  of  Sponsoring 
Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework. 

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United  States),  the  consolidated  financial  statements  and  financial  statement  schedule  of  Diodes  Incorporated  and 
Subsidiaries as of and for the year ended December 31, 2005, and our report dated March 10, 2006 expressed an unqualified 
opinion on those financial statements and financial statement schedule.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

Board of Directors and Stockholders 
Diodes Incorporated and Subsidiaries 

We have audited the accompanying consolidated balance sheets of Diodes Incorporated and Subsidiaries as of December 31, 
2005 and 2004 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,  2005.    These  financial  statements  are  the  responsibility  of  the  Company's 
management.  Our responsibility is to express an opinion on these financial statements based on our audits. 

We  conducted  our  audits  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United 
States).  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about  whether  the 
consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence 
supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that 
our audits provide a reasonable basis for our opinion.  

In our opinion, the financial statements referred to above present fairly,  in  all  material  respects,  the  consolidated  financial 
position  of  Diodes  Incorporated  and  Subsidiaries  as  of  December  31,  2005  and  2004,  and  the  consolidated  results  of  its 
operations and cash flows for each of the years in the three year period ended December 31, 2005, in conformity with U.S. 
generally accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
the effectiveness of Diodes Incorporated and Subsidiaries’ internal control over financial reporting as of December 31, 2005, 
based  on  criteria  established  in  Internal  Control  -  Integrated  Framework  issued  by  the  Committee  of  Sponsoring 
Organizations of the Treadway Commission, and our report dated March 10, 2006 expressed an unqualified opinion thereon.

DIODES INCORPORATED AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

NOTE  1 – SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES 

Nature  of  operations  –  Diodes  Incorporated  and  its  subsidiaries  manufacture  and  distribute  discrete  semiconductor 
devices  to  manufacturers  in  the  communications,  computing,  consumer  electronics,  industrial,  and  automotive  markets.    The 
Company's  products  include  small-signal  transistors  and  MOSFETs,  transient  voltage  suppressors  (TVSs),  zeners,  Schottkys, 
diodes, rectifiers, bridges and silicon wafers.  The products are sold primarily throughout North America, Asia and Europe. 

Principles of consolidation - The consolidated financial statements include the accounts of the parent company, Diodes 
Incorporated  (Diodes-North  America),  its  wholly-owned  subsidiaries;  Diodes  Incorporated  Taiwan  Co.,  Ltd.  (Diodes-Taiwan), 
Diodes Hong Kong, Ltd. (Diodes-Hong Kong) and FabTech, Inc. (FabTech or Diodes-FabTech); and its majority (95%) owned 
subsidiaries,  Shanghai  KaiHong  Electronics  Co.,  Ltd.  (Diodes-China)  and  Shanghai  KaiHong  Technology  Co.,  Ltd.  (Diodes-
Shanghai).  All significant intercompany balances and transactions have been eliminated in consolidation. 

Revenue  recognition –  Revenue is recognized when there is persuasive  evidence  that  an  arrangement  exists,  when 
delivery  has  occurred,  when  our  price  to  the  buyer  is  fixed  or  determinable  and  when  collectibility  of  the  receivable  is 
reasonably  assured.  These  elements  are  met  when  title  to  the  products  is  passed  to  the  buyers,  which  is  generally  when  our 
product  is  shipped  to  both  original  equipment  manufacturers  (OEMs)  and  electronics  component  distributors.    The  Company 
reduces revenue in the period of sale for estimates of product returns and other allowances. 

In 2003, Diodes-China received approximately $254,000 in high-technology grants as an incentive for further investment 
from the local Chinese government.  The grants were unrestricted and available upon receipt to fund the operations of Diodes-
China.  The Company recognized this grant income when received and recorded them within “other income” on the accompanying 
statements of income.  No high-technology grant income was received in 2004 or 2005 and management does not expect this type 
of income in the future. 

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.  Cash balances are usually in excess of Federal and/or foreign deposit insurance 
limits.    The  Company  has  not  experienced  any  losses  related  to  these  balances,  and  management  believes  its  credit  risk  to  be 
minimal.  

               Short-Term Investments – The Company’s short-term investments consist primarily of municipal bonds, all of which 
are classified as available-for-sale. Available-for-sale securities are recorded at fair value, and unrealized holding gains and losses 
are recorded, net of tax, as a separate component of accumulated other comprehensive income. Available-for-sale securities with 
remaining maturities of less than one year and those identified by management at time of purchase for funding operations in less 
than one year are classified as short-term, and all other available-for-sale securities are classified as long-term. Unrealized losses 
are charged against net earnings when a decline in fair value is determined to be other than temporary.  Realized gains and losses 
are accounted for on the specific identification method.  

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 both finished goods inventory and raw material inventory is evaluated 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.  Based upon this analysis, as well as an inventory aging analysis, a reserve 
for obsolete and slow-moving inventory is accrued (see Note 2). 

Property,  plant  and  equipment  –  Property,  plant  and  equipment  are  depreciated  using  straight-line  and  accelerated 
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 (see Note 4). 

Goodwill  –  The  Company  accounts  for  goodwill  in  accordance  with  Statement  of  Financial  Accounting  Standards 

(SFAS) No. 142 (“Goodwill and Other Intangible Assets”), under which goodwill is tested for impairment at least annually.

NOTE  1 – SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES 

(Continued) 

An independent appraiser hired by the Company, performed the required impairment tests of goodwill as of January 
1, 2005 and 2006, and has determined that the goodwill is fully recoverable.  No goodwill was acquired or impaired during 
the years ended December 31, 2003, 2004 and 2005.  As of December 31, 2005, goodwill for Diodes-FabTech and Diodes-
China was $4.2 million and $0.9 million, respectively. 

Impairment  on  long-lived  assets  –  Certain  long-lived  assets  of  the  Company  are  reviewed  at  least  annually  as  to 
whether  their  carrying  values  have  become  impaired  in  accordance  with  SFAS  No.  144,  “Accounting  for  the  Impairment  or 
Disposal  of  Long-Lived  Assets.”    Management  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 the projected discounted 
cash flows from related operations.  As of December 31, 2005, 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 (see 
Note 8). 

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 the electronics  manufacturing  and  distribution  industries.    The  Company  performs  on-
going credit evaluations of its customers and generally requires no collateral from its customers.  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 approximately fair 
value due to their current market conditions, maturity dates and other factors. Short-term investments classified as available 
for sale are recorded at market value with unrealized gains or losses reflected in other accumulated comprehensive income or 
loss.  

Treasury  shares  –  In  December  2005,  the  Board  of  Directors  canceled  the  2,420,262  shares  held  in  treasury.    The 

cancellation has no net impact on stockholders’ equity, shares outstanding or shares used to compute earnings per share.  

Equity investment – On December 20, 2005, the Company acquired an 18.87% equity interest of Anachip Corporation, 
a  private-held  Taiwanese  fabless  analog  IC  company,  for  approximately  $5.9  million.    The  investment  is  being  accounted  for 
under  the  equity  method  as  required  by  APB  No.  18,  "The  Equity  Method  of  Accounting  for  Investments  in  Common  Stock." 
However, the Company did not record income from the investment on the consolidated financial statements for the ten days ending 
December 31, 2005, as the amount was not material.  In January 2006, the Company increased its equity ownership of Anachip 
Corporation to 99.81%.  As a result, Anachip will be consolidated beginning the first fiscal quarter of 2006. 

Stock split – On December 1, 2005, the Company affected a three-for-two stock split for shareholders of record as 
of  November  18,  2005  in  the  form  of  a  50%  stock  dividend.    All  share  and  per  share  amounts  in  the  accompanying 
consolidated financial statements and footnotes disclosures have been retroactively adjusted to reflect the effect of this stock 
split. 

Use of estimates – The preparation of financial statements in conformity with accounting principles generally accepted 
in the United States of America requires that management make estimates and assumptions that affect the amounts reported in the 
consolidated financial statements and accompanying notes.  Actual results could differ materially from those estimates.

Earnings per share – Earnings per share are based upon the weighted average number of shares of common stock and 
common stock equivalents outstanding, net of common stock held in treasury.  Earnings per share is computed using the “treasury 
stock method” under the Financial Accounting Standards Board (FASB) Statement No. 128. 

For the years ended December 31, 2003, 2004 and 2005, options outstanding for 1,793,000 shares, 0 shares, and 682,000 
shares, respectively, of common stock have been excluded from the computation of diluted earnings per share because their effect 
was anti-dilutive.

Stock-based  compensation  – The Company maintains stock-based compensation plans for its board of directors, 
officers,  and  key  employees,  which  provide  for  non-qualified  and  incentive  stock  options.    The  plans  are  described  more 
fully in Note 9.  With the issuance in mid-December 2004 by FASB of SFAS No. 123(R), “Share-Based Payments,” which 
is a revision to SFAS No. 123, “Accounting for Stock-Based Compensation,” which was issued in 1995, the Company will 
begin reporting the fair value of stock-based compensation as an expense in its financial statements beginning in 2006 (see 
discussion  in  “Recently  Issued  Accounting  Pronouncements  and  Proposed  Accounting  Changes”  below).    Prior  to 
implementation  of  this  new  standard,  the  Company  accounted  for  those  plans  under  the  recognition  and  measurement 
principles  of  APB  Opinion  No.  25,  “Accounting  for  Stock  Issued  to  Employees,”  and  related  Interpretations.    No 
compensation cost was reflected in net income for stock options, as all options granted under those plans have an exercise 
price  equal  to  or  greater  than  the  market  value  of  the  underlying  common  stock  on  the  date  of  the  grant.    As  required  by 
SFAS No. 148, “Accounting for Stock-Based Compensation—Transition and Disclosure, an amendment of FASB Statement 
No.  123,”  the  following  table  illustrates  the  effect  on  net  income  and  earnings  per  common  share  as  if  the  Company  had 
applied the fair value recognition provisions of SFAS No. 123 to stock-based compensation for each period presented:

The pro forma information recognizes as compensation the value of stock options granted using the Black-Scholes 
option  pricing  model  which  takes  into  account  as  of  the  grant  date,  the  exercise  price  and  expected  life  of  the  option,  the 
current price of underlying stock and its expected volatility, expected dividends on the stock, expected  forfeitures  and  the 
risk-free  interest  rate  for  the  term  of  the  option.    The  following  is  the  weighted  average  of  the  data  used  to  calculate  the 
estimated fair value:

The  Company’s  valuations  are  based  upon  a  single  option  valuation  approach  using  the  Black-Scholes  option 
valuation  model.    The  Black-Scholes  option  valuation  model  was  developed  for  use  in  estimating  the  fair  value  of  traded 
options, which have no vesting restrictions and are fully transferable and negotiable in a free trading market.  In addition, 
option valuation models require the input of highly subjective assumptions, including the expected stock price volatility and 
expected life of the option.  Because the Company’s stock options have characteristics significantly different from those of 
freely  traded  options,  and  changes  in  the  subjective  input  assumptions  can  materially  affect  the  Company’s  fair  value 
estimate  of  those  stock  options,  in  the  Company’s  opinion,  existing  valuations  models,  including  Black-Scholes,  are  not 
reliable single measures and may misstate the fair value of the Company’s stock options.  Because Company stock options 
do  not  trade  on  a  secondary  exchange,  recipients  can  receive  no  value  nor  derive  any  benefit  from  holding  stock  options 
under these plans without an increase, above the grant price, in the market price of the Company’s stock.  Such an increase in 
stock price would benefit all stockholders commensurately.

Derivative  financial  instrument  –  The  Company  used  an  interest  rate  swap  agreement  to  hedge  its  exposure  to 
variability  in  expected  future  cash  flows  resulting  from  interest  rate  risk  related  to  a  portion  of  its  long-term  debt.    The 
interest  rate  swap  agreement  applied  to  25%  of  the  Company’s  long-term  debt  and  expired  November  30,  2004.    Market 
value of the swap as of December 31, 2004 and 2005 is included in “Accumulated Other Comprehensive Loss”.  The swap 
contract  is  inversely  correlated  to  the  related  hedged  long-term  debt  and  was  therefore  considered  an  effective  cash  flow 
hedge of the underlying long-term debt.  The level of effectiveness of the hedge was measured by the changes in the market 
value of the hedged long-term debt resulting from fluctuation in interest rates.  As a matter of policy, the Company does not 
enter into derivative transactions for trading or speculative purposes. 

Functional  currencies  and  foreign  currency  translation  –  Through  its  subsidiaries,  the  Company  maintains 
operations  in  Taiwan,  Hong  Kong  and  China.    The  Company  believes  the  New  Taiwan  (“NT”)  dollar  as  the  functional 
currency  at  Diodes-Taiwan  most  appropriately  reflects  the  current  economic  facts  and  circumstances  of  the  operations.  
Assets and liabilities recorded in NT dollar are translated at the exchange rate on the balance sheet date. Income and expense 
accounts are translated at the average monthly exchange rate during the year. Resulting translation adjustments are recorded 
as a separate component of accumulated other comprehensive income/(loss).  

The Company uses the U.S. dollar as the functional currency in Diodes-China, Diodes-Shanghai and Diodes-Hong 
Kong,  as  substantially  all  monetary  transactions  are  made  in  that  currency,  and  other  significant  economic  facts  and 
circumstances  currently  support  that  position.    As  these  factors  may  change  in  the  future,  the  Company  will  periodically 
assess  its  position  with  respect  to  the  functional  currency  of  its  foreign  subsidiaries.    Included  in  net  income  are  foreign 
currency  exchange  losses  of  approximately  $115,000,  and  $424,000  for  the  years  ended  December  31,  2003  and  2004, 
respectively, and exchange gains of $79,000 for the year ended December 31, 2005. 

Comprehensive income – Accounting principles generally require that recognized revenue, expenses, gains and losses 
be included in net income.  Although certain changes in assets and liabilities are reported as a separate component of the equity 
section of the balance sheet, such items, along with net income, are components of comprehensive income.  The components of 
other  comprehensive  income  include  foreign  currency  translation  adjustments  and  changes  in  the  unrealized  loss  on  derivative 
instruments from swap liability.  Foreign currency translation adjustments are presented without a tax effect as the amounts relate 
primarily to subsidiaries with indefinitely reinvested earnings. 

Recently  issued  accounting  pronouncements  and  proposed  accounting  changes – In May 2005, the Financial 
Accounting Standards Board (FASB) issued SFAS No. 154, “Accounting Changes and Error Corrections, A Replacement of 
APB Opinion No. 20 and FASB Statement No. 3.” SFAS 154 requires retrospective application to prior periods’ financial 
statements for changes in accounting principles, unless it is impracticable to determine either the period-specific effects or 
the  cumulative  effect  of  the  change.  SFAS  154  also  requires  that  retrospective  application  of  a  change  in  accounting 
principle be limited to the direct effects of the change. Indirect effects of a change in accounting principle, such as a change 
in non-discretionary profit-sharing payments resulting from an accounting change, should be recognized in the period of the 
accounting change. SFAS 154 also requires that a change in depreciation, amortization, or depletion method for long-lived, 
non-financial assets be accounted for as a change in accounting estimate effected by a change in accounting principle. SFAS 
154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. 
Early adoption is permitted for accounting changes and corrections of errors made in fiscal years beginning after the date this 
Statement  is  issued.  The  Company  does  not  anticipate  a  material  impact  on  the  financial  statements  from  the  adoption  of  this 
consensus.

(Continued) 

In March 2005, the FASB issued FASB Interpretation (FIN) No. 47, “Accounting for Conditional Asset Retirement 
Obligations,  An  Interpretation  of  FASB  Statement  No.  143,”  which  requires  an  entity  to  recognize  a  liability  for  the  fair 
value of a conditional asset retirement obligation when incurred if the liability’s fair value can be reasonably estimated. The 
adoption of this Interpretation did not have a material impact on the Company’s consolidated financial position, results of 
operations or cash flows. 

In December 2004, FASB issued SFAS No. 123(R). This new standard requires companies to adopt the fair value 
methodology of valuing stock-based compensation and recognizing that valuation in the financial statements from the date of 
grant.  Accordingly,  the  adoption  of  SFAS No. 123(R)’s  fair  value  method  will  have  a  significant  impact  on  our  results  of 
operations, although it will have no impact on our overall financial position. The impact of adoption of SFAS No. 123(R) 
cannot  be  predicted  at  this  time  because  it  will  partially  depend  on  levels  of  share-based  payments  granted  in  the  future. 
However,  had  we  adopted  SFAS No. 123(R)  in  prior  periods,  the  impact  of  that  standard  would  have  approximated  the 
impact of SFAS No. 123 as shown in the Stock-based Compensation table contained in Note 1 of our financial statements. 
SFAS No. 123(R) also requires the benefits of tax deductions in excess of recognized compensation cost to be reported as a  
financing cash flow, rather than as an operating cash flow as required under current literature. We are currently evaluating 
several  option  valuation  models  in  order  to  calculate  the  required  compensation  expense.  We  have  elected  to  adopt  the 
provisions  of  SFAS No. 123(R)  on  a  modified  prospective  application  method  with  no  restatement  of  any  prior  periods. 
SFAS No. 123(R) is effective for us as of the beginning of the fiscal year ending December 31, 2006. 

In December 2004, the FASB also issued SFAS No. 151, “Inventory Costs, an amendment of ARB No. 43, Chapter 
4.” This standard clarifies that abnormal amounts of idle facility expense, freight, handling costs and wasted material should 
be  expensed  as  incurred  and  not  included  in  overhead.  In  addition,  this  standard  requires  that  the  allocation  of  fixed 
production overhead costs to inventory be based on the normal capacity of the production facilities. The provisions of this 
standard are effective for the fiscal years beginning after June 15, 2005. The Company is currently evaluating the potential 
impact of this standard on its financial position and results of operations, but does not believe the impact of the change will 
be material. 

On October 22, 2004, the American Jobs Creation Act of 2004 was passed, which raised a number of issues with 
respect to accounting for income taxes. In response, on December 21, 2004, the FASB issued two FASB Staff Positions, or 
FSP,  FSP  109-1—  Application  of  FASB  Statement  No. 109,  Accounting  for  Income  Taxes,  to  the  Tax  Deduction  on 
Qualified  Production  Activities  Provided  by  the  American  Jobs  Creation  Act  of  2004  and  FSP  109-2—  Accounting  and 
Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of 2004, which 
became effective for us upon issuance. 

The  AJCA  provides  a  deduction  for  income  from  qualified  domestic  production  activities,  to  be  phased  in  from 
2005 through 2010, which is intended to replace the existing extra-territorial income exclusion for foreign sales. In FSP 109-
1,  the  FASB  decided  the  deduction  for  qualified  domestic  production  activities  should  be  accounted  for  as  a  special 
deduction under SFAS No. 109, rather than as a rate reduction. Accordingly, any benefit from the deduction will be reported 
in the period in which the deduction is claimed on the tax return. No adjustment to deferred taxes was required. The adoption 
of this standard is not expected to have significant impact on Company’s consolidated financial statements.   

The AJCA also creates a temporary incentive for U.S. corporations to repatriate accumulated income earned abroad 
by  providing  an  85.0%  dividends  received  deduction  for  certain  dividends  from  controlled  foreign  corporations.  The 
deduction  is  subject  to  a  number  of  limitations  and  uncertainty  remains  as  to  how  to  interpret  numerous  provisions  in  the 
AJCA.  FSP  109-2  addresses  when  to  reflect  in  the  financial  statements  the  effects  of  the  one-time  tax  benefit  on  the 
repatriation of foreign earnings. Under SFAS No. 109, companies are normally required to reflect the effect of new tax law 
changes in the period of enactment. FSP 109-2 provides companies additional time to determine the amount of earnings, if 
any, that they intend to repatriate under the AJCA’s provisions. See Note 8 of our financial statements for more discussion of 
the impact of the AJCA, including the impact on our repatriation of foreign earnings.

(Continued) 

In  November  2004,  the  Emerging  Issues  Task  Force,  or  EITF,  reached  a  consensus  on  EITF  Issue  No. 03-13, 
Applying the Conditions in Paragraph 42 of FASB Statement No. 144, Accounting for the Impairment or Disposal of Long-
Lived Assets, in Determining Whether to Report Discontinued Operations. The consensus provides guidance in determining: 
(1) which cash flows should be taken into consideration when assessing whether the cash flows of the disposal component 
have been or will be eliminated from the ongoing operations of the entity, (2) the types of involvement ongoing between the 
disposal component and the entity disposing of the component that constitute continuing involvement in the operations of the 
disposal  component,  and  (3) the  appropriate  (re)assessment  period  for  purposes  of  assessing  whether  the  criteria  in 
paragraph 42 have been met. The consensus was ratified by the FASB at their November 30, 2004 meeting and should be 
applied to a component of an enterprise that is either disposed of or classified as held for sale in fiscal periods beginning after 
December 15, 2004. We do not anticipate a material impact on our financial statements from the adoption of this consensus. 

In September 2004, the EITF reached a consensus on EITF Issue No. 04-10, Applying Paragraph 19 of FAS 131 in 
determining whether to aggregate operating segments that do not meet the quantitative thresholds. The consensus states that 
operating segments that do not meet the quantitative thresholds can be aggregated only if aggregation is consistent with the  

objective and basic principles of SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information, the 
segments have similar economic characteristics, and the segments share a majority of the aggregation criteria (a)-(e) listed in 
paragraph 17 of SFAS No. 131. The effective date of the consensus in this Issue is for fiscal years ending after October 13, 
2004. The ratification of this Issue did not have an impact on our financial reporting. 

In  March  2004,  the  EITF  reached  a  consensus  on  the  remaining  portions  of  EITF 03-01,  The  Meaning  of  Other-
Than-Temporary Impairment and Its Application to Certain Investments with an effective date of June 15, 2004. EITF 03-01 
provides new disclosure requirements  for other-than-temporary impairments on debt and equity investments. Investors  are 
required  to  disclose  quantitative  information  about:  (1) the  aggregate  amount  of  unrealized  losses,  and  (2) the  aggregate 
related fair values of investments with unrealized losses, segregated into time periods during which the investment has been 
in  an  unrealized  loss  position  of  less  than  12 months  and  greater  than  12 months.  In  addition,  investors  are  required  to 
disclose the qualitative information that supports their conclusion that the impairments noted in the qualitative disclosure are 
not other-than temporary. We determined that EITF 03-01 would not have a material impact on our financial statements. 

In December 2003, the FASB issued FASB Interpretation No. 46R, or FIN 46R, Consolidation of Variable Interest 
Entities, a revision to Interpretation No. 46. FIN 46R clarifies the application of consolidation accounting for certain entities 
that  do  not  have  sufficient  equity  at  risk  for  the  entity  to  finance  its  activities  without  additional  subordinated  financial 
support from other parties or in which equity investors do not have the characteristics of a controlling financial interest; these 
entities are referred to as “variable interest entities.” Variable interest entities within the scope of FIN 46R are required to be 
consolidated by their primary beneficiary. The primary beneficiary of a variable interest entity is determined to be the party 
that  absorbs  a  majority  of  the  entity’s  expected  losses,  receives  a  majority  of  its  expected  returns,  or  both.  FIN 46R  also 
requires  disclosure  of  significant  variable  interests  in  variable  interest  entities  for  which  a  company  is  not  the  primary 
beneficiary. We have assessed Diodes-Shanghai under the provisions of FIN 46R and have concluded that our investment in 
Diodes-Shanghai does not meet the criteria for consolidation under the standard. However Diodes-Shanghai is consolidated 
under other applicable accounting literature. We will periodically review our investment in Diodes-Shanghai to insure that 
we comply with the guidelines prescribed by FIN 46R. 

Reclassifications  –  Certain  prior  year  amounts,  as  well  as  unaudited  quarterly  financial  data  presented  in  the 
accompanying  consolidated  financial  statements,  have  been  reclassified  to  conform  to  the  current  year  financial  statement 
presentation.    On  December  1,  2005  the  Company  affected  a  three-for-two  stock  split  for  shareholders  of  record  as  of

As an incentive for establishing our first Shanghai-based manufacturing subsidiary, Diodes-China, in 1996, and in 
accordance  with  the  taxation  policies  of  China,  Diodes-China,  received  preferential  tax  treatment  for  the  years  ended 
December 31, 1996 through 2005. 

Diodes-China  is  located  in  the  Songjiang  district,  where  the  standard  central  government  tax  rate  is  24.0%. 
However, as an incentive for establishing Diodes-China, the earnings of Diodes-China were subject to a 0% tax rate by the 
central government from 1996 through 2000, and to a 12.0% tax rate from 2001 through 2005.  For 2006 and future years, 
Diodes-China’s earnings will continue to be subject to a 12.0% tax rate provided it exports at least 70% of its net sales.  In 
addition, due to an $18.5 million permanent re-investment of Diodes-China earnings in 2004, Diodes-China has applied to 
the  Chinese  government  for  additional  preferential  tax  treatment  on  earnings  that  are  generated  by  this  $18.5  million 
investment.    If  approved,  those  earnings  will  be  exempted  from  central  government  income  tax  for  two  years,  and  then 
subject to a 12.0% tax rate for the following three years. 

In addition, the earnings of Diodes-China would ordinarily be subject to a standard local government tax rate of 3.0%.  
However,  as  an  incentive  for  establishing  Diodes-China,  the  local  government  waived  this  tax  from  1996  through  2005.  
Management expects this tax to be waived for at least the first half of 2006, however, the local government can re-impose this 
tax at any time at its discretion.

NOTE 8 – INCOME TAXES (Continued) 

In  2004,  we  established  our  second  Shanghai-based  manufacturing  facility,  Diodes-Shanghai,  located  in  the 
Songjiang  Export  Zone  of  Shanghai,  China.    In  the  Songjiang  Export  Zone,  the  central  government  standard  tax  rate  is 
15.0%.  There  is  no  local  government  tax.    During  2004,  Diodes-Shanghai  earnings  were  subject  to  the  standard  15.0% 
central government tax rate.  As an incentive for establishing Diodes-Shanghai, for 2005 and 2006 the earnings of Diodes-
Shanghai are exempted from central government income tax, and for the years 2007 through 2009 its earnings will be subject 
to a 7.5% tax rate.  From 2010 onward, provided that Diodes-Shanghai exports over 70% of its net sales, its earnings will be 
subject to a 10.0% tax rate. 

Earnings of Diodes-Taiwan are currently subject to a tax rate of 35%, which is comparable to the U.S. Federal tax 
rate  for  C  corporations.    Earnings  of  Diodes-Hong  Kong  are  currently  subject  to  a  17.5%  tax  for  local  sales  and/or  local 
source sales, all other sales are foreign income tax-free. 

In  accordance  with  United  States  tax  law,  the  Company  receives  credit  against  its  U.S.  Federal  tax  liability  for 
corporate  taxes  paid  in  foreign  jurisdictions.    The  repatriation  of  funds  from  foreign  subsidiaries  to  the  Company  may  be 
subject to Federal and state income taxes.   

As  of  December  31,  2005,  accumulated  and  undistributed  earnings  of  Diodes-China  and  Diodes-Shanghai  are 
approximately $51.2 million, including $28.5 million of restricted earnings (which are not available for dividends).  Through 
March 31, 2002, the Company had not recorded deferred U.S. Federal or state tax liabilities (estimated to be $8.9 million as 
of  March  31,  2002)  on  these  cumulative  earnings  since  the  Company,  at  that  time,  considered  this  investment  to  be 
permanent, and had no plans or obligation to distribute all or part of that amount from China to the United States.  Beginning 
in April 2002, the Company began to record deferred taxes on a portion of the China earnings in preparation of a dividend 
distribution.  In the year ended December 31, 2004, the Company received a dividend of approximately $5.7 million from its 
Diodes-China subsidiary, for which the tax effect is included in U.S. Federal and state taxable income. 

On October 22, 2004, the President of the United States signed the American Jobs Creation Act (AJCA) into law.  
Originally intended to repeal the extraterritorial income (ETI) exclusion, which had triggered tariffs by the European Union, 
the AJCA expanded to cover a wide range of business tax issues.  Among other items, the AJCA establishes a phased repeal 
of the ETI, a new incentive tax deduction for U.S. corporations to repatriate cash from foreign subsidiaries at a reduced tax 
rate  (a  deduction  equal  to  85%  of  cash  dividends  received  in  the  year  elected  that  exceeds  a  base-period  amount)  and 
significantly revises the taxation of U.S. companies doing business abroad. 

At December 31, 2004, the Company made a minimum estimate for repatriating cash from its subsidiaries in China 
and Hong Kong of $8.0 million under the AJCA, and recorded an income tax expense of approximately $1.3 million.  Under 
the  guidelines  of  the  AJCA,  the  Company  developed  a  required  domestic  reinvestment  plan,  covering  items  such  as  U.S. 
bank  debt  repayment,  U.S.  capital  expenditures  and  U.S.  research  and  development  activities,  among  others,  to  cover  the 
dividend repatriation.  During 2005, the Company completed a quantitative analysis of the benefits of the AJCA, the foreign 
tax  credit  implications,  and  state  and  local  tax  consequences  of  the  impact  of  the  AJCA  on  the  Company’s  plans  for 
repatriation.  Based on the analysis, the Company repatriated $24.0 million from its foreign subsidiaries in 2005. 

The  Company  is  evaluating  the  need  to  provide  additional  deferred  taxes  for  the  future  earnings  of  its  foreign 
subsidiaries  to  the  extent  such  earnings  may  be  appropriated  for  distribution  to  the  Company’s  corporate  office  in  North 
America, and as further investment strategies with respect to foreign earnings are determined.  Should the Company’s North 
American  cash  requirements  exceed  the  cash  that  is  provided  through  the  domestic  credit  facilities,  cash  can  be  obtained 
from the Company’s foreign subsidiaries.  However, the distribution of any unappropriated funds to the U.S. will require the 
recording of income tax provisions on the U.S. entity, thus reducing net income.  As of December 31, 2005, the Company 
has  recorded  approximately  $1.1  million  in  deferred  taxes  for  earnings  of  its  foreign  subsidiaries,  primarily  Diodes-Hong

NOTE  10 – RELATED PARTY TRANSACTIONS 

Lite-On  Semiconductor  Corporation  (LSC)  –  In  July  1997,  Vishay  Intertechnology,  Inc.  (Vishay)  and  the  Lite-On 
Group, a Taiwanese consortium, formed a joint venture - Vishay/Lite-On Power Semiconductor Pte., LTD. (Vishay/LPSC) - to 
acquire  Lite-On  Power  Semiconductor  Corp.  (LPSC),  a  then  37%  shareholder  of  the  Company  and  a  member  of  the  Lite-On 
Group of the Republic of China.  The Lite-On Group is a leading manufacturer of power semiconductors, computer peripherals, 
and communication products.  

In March 2001, Vishay agreed to sell its 65% interest in the Vishay/LPSC joint venture to the Lite-On Group, the 35% 
joint  venture  partner.    Because  of  this  transaction,  the  Lite-On  Group,  through  LPSC,  its  wholly-owned  subsidiary,  indirectly 
owned approximately 37% of the Company’s common stock.  In December 2001, LPSC merged with Dyna Image Corporation of 
Taipei, Taiwan.  Dyna Image is the world’s largest manufacturer of Contact Image Sensors (CIS), which are used in fax machines, 
scanners, and copy machines.  The combined company is called Lite-On Semiconductor Corporation (LSC).  At December 31, 
2005, LSC owned approximately 22.9% of the Company’s common stock.  The Company considers its relationship with LSC to 
be mutually beneficial and the Company and LSC plans to continue its strategic alliance as it has since 1991.   

The  Company  also  leases  warehouse  space  from  Lite-on  HK  Ltd.  for  its  operations  in  Hong  Kong.    Such 
transactions  are  on  terms  no  less  favorable  to  the  Company  than  could  be  obtained  from  unaffiliated  third  parties.    As 
required by Nasdaq, the Audit Committee of the Board of Directors has approved the contracts associated with the related 
party transactions.  The Company buys product from, and sell products to, LSC.

$0 as of December 31, 2004 and December 31, 2005, respectively.  Terms of the debt are indicated in Note 5.  As per the terms of 
the acquisition agreement, LSC entered into a volume purchase agreement with FabTech pursuant to which LSC is obligated to 
purchase from FabTech, and FabTech is obligated to manufacture and sell to LSC, silicon wafers. 

 As  part  of  the  FabTech  acquisition,  the  Company  entered  into  management  incentive  agreements  with  several 
members of FabTech’s management.  The agreements provide a guaranteed aggregate $375,000 annual payment as well as 
contingent bonuses based on the annual profitability of FabTech (subject to a maximum annual amount).  Any portion of the 
guaranteed  and  contingent  liability  paid  by  FabTech  is  reimbursed  by  LSC.    Guaranteed  and  maximum  contingent  bonus 
payments provided for by the management incentive agreements for the year ended December 31, 2004 (the final year of the 
agreements)  were  $375,000  and  $1.2  million,  respectively.    No  contingent  bonus  was  earned  or  paid  in  the  years  2003 
through 2005.   

Other related party – The Company sells product to, and purchases inventory from, companies owned by its 5% 
minority  shareholder,  Keylink  International  (formerly  Xing  International),  in  Diodes-China  and  Diodes-Shanghai.    In

manufacturing  process  (metal  plating  and  environmental  services)  to,  and  pays  a  consulting  fee  to,  its  5%  minority 
shareholder.    Total  amounts  for  these  services  for  the  years  ended  December  31,  2003,  2004,  and  2005  were  $3,464,000,

NOTE 14 – SUBSEQUENT EVENT 

On December 20, 2005, the Company announced it had signed a definitive stock purchase agreement to acquire Anachip 

Corporation, a Taiwanese fabless analog IC company. 

Headquartered  in  the  Hsinchu  Science  Park  in  Taiwan,  Anachip’s  main  product  focus  is  Power  Management  ICs.  
Anachip's products are widely used in LCD monitor/TV's, wireless 802.11 LAN access points, brushless DC motor fans, portable 
DVD players, datacom devices, ADSL modems, TV/satellite set-top boxes, and power supplies. 

The selling shareholders of Anachip stock included LSC (which owned approximately 60% of Anachip’s outstanding 
capital  stock),  and  two  Taiwanese  venture  capital  firms  (together  owning  approximately  20%  of  Anachip’s  stock),  as  well  as 
current and former Anachip employees. 

At December 31, 2005, the Company had purchased an aggregate of 9,433,613 shares (or approximately 18.9%) of the 
50,000,000  outstanding  shares  of  the  capital  stock  of  Anachip.    On  January 10,  2006,  (the  closing  date  of  the  acquisition)  the 
Company  purchased  an  additional  40,470,212  shares  and  therefore,  the  Company  holds  approximately  99.81%  of  the  Anachip 
capital stock.  At December31, 2005, the investment in Anachip is recorded under the equity method, however, the Company did 
not record income from the investment on the consolidated financial statements for the ten days ending December 31, 2005, as the 
amount  was  not  material.    As  of  result  of  the  additional  Anachip  interest  acquired  during  2006,  Anachip  will  be  consolidated 
beginning the first fiscal quarter of 2006.

The  purchase  price  of  the  acquisition  was  NT$20  per  share  (approximately  US$30  million).    The  following  table 
summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition.  The Company is in 
the process of obtaining third-party valuations of certain intangible assets; thus, the allocation of the purchase price is subject to
