Diodes Incorporated
2015 Letter to Stockholders

A Year in Review
Diodes Incorporated closed 2015 with increased market share, the achievement of our 25th consecutive year of profitability, as
well as the successful completion of the acquisition of Pericom Semiconductor Corporation. Pericom is well-aligned with our
acquisition strategy and broadens our analog footprint, while also adding a strong mixed-signal connectivity offering that will
drive expanded product contents in target applications.

When looking back over this past year, 2015 was characterized by weaker demand across several key end markets and
geographies. The softer environment impacted loading and utilization at our manufacturing facilities, but also provided unique
opportunities to achieve market share gains at key customers. Gross margins were under pressure especially in the second half
of the year. However, we believe Diodes is well positioned for margin expansion in 2016 based on improvements in product mix
and manufacturing performance, as well as the benefit from previous cost reductions and the Pericom acquisition. As in past
cycles, our flexible business model enabled us to respond quickly to changing market conditions in order to preserve revenue and
profitability.

During the year, we generated approximately $118 million in cash flow from operations, which allowed us to return capital to our
stockholders while also continuing to pay-down our long-term debt and invest in our future. In early November, our Board
approved a stock repurchase program authorizing purchases of up to $100 million of our common stock over a four-year period.
In the fourth quarter 2015, we returned approximately $11 million to our stockholders through stock repurchases. We ended the
year with $283 million in cash, cash equivalents and short-term cash investments, and $571 million of working capital.

New Products Drive Share Gains
Diodes continued to make great progress on our new product development with a growing pipeline of design wins across our
target end markets. In particular, we have been strategically focusing our efforts on increasing contents in the industrial and
automotive markets. We introduced a growing number of new products that meet the stringent design and quality requirements
of these markets. We also continued to broaden our product offerings for high-volume portable electronics with increasing share
and design wins in smartphones and wireless charging. Diodes’ expertise in developing products using small, thin profile
packages for space-constrained applications remains a key driver of our expanded contents with our customers. We remain
committed to investing in product innovation to further differentiate our products in terms of technology, wafer manufacturing
and packaging. As a result, Diodes is well positioned to capture market share in the emerging wearables and Internet of Things
markets based on our capabilities in miniaturization and power efficient packaging.

Delivering Consistent Profitable Growth
In summary, despite the weaker demand environment throughout 2015, we continued to gain market share and capitalize on our
expanding product portfolio and design win success across our end markets. We believe there are significant opportunities in the
coming year as we integrate the Pericom acquisition and further broaden our contents at customers and increase end market
penetration. As part of the Pericom integration efforts, we are focused on maximizing sales, design, operations, and
administrative efficiencies. Additionally, we will continue to place a strong emphasis on the portable and wearable space as well
as the industrial and automotive markets, where we have solid momentum entering the new year.

Finally, we would like to take this opportunity to thank stockholders, customers, employees and suppliers for your continued
support and confidence in Diodes. We remain committed to generating long-term value and profitable growth for our
stockholders.

Sincerely,

Dr. Keh-Shew Lu
President & Chief Executive Officer

Raymond Soong
Chairman of the Board

GENERAL  

Business.  

PART I  

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

We  design,  manufacture  and  market  these  semiconductors  for  diverse  end-use  applications.  Semiconductors,  which  provide 
electronic  signal  amplification  and  switching  functions,  are  basic  building-blocks  that  are  incorporated  into  almost  every  electronic 
device. We believe that our focus on application-specific standard products utilizing innovative, highly efficient packaging and cost-
effective  process  technologies,  coupled  with  our  collaborative,  customer-focused  product  development,  gives  us  a  meaningful 
competitive advantage relative to other semiconductor companies.  

Our product portfolio addresses the design needs of advanced electronic equipment, including high-volume consumer electronic 
devices such as digital media players, smartphones, tablets, notebook computers, flat-panel displays, mobile handsets, digital cameras 
and  set-top  boxes.  We  believe  that  we  have  particular  strength  in  designing  innovative,  highly  power  efficient  semiconductors  in 
miniature  packaging  for  applications  with  a  critical  need  to  minimize  product  size  while  maximizing  power  density  and  overall 
performance,  and  at  a  lower  cost  than  alternative  solutions.  Our  product  line  includes  over  10,000  products,  and  we  shipped 
approximately 40 billion units, 44 billion units, and 41 billion units in 2015, 2014 and 2013, respectively. From 2010 to 2015, our net 
sales grew from $613 million to $849 million, representing a compound annual growth rate of greater than 6%.  

We  serve  over  250  direct  customers  worldwide,  which  consist  of  original  equipment  manufacturers  (“OEM”)  and  electronic 
manufacturing services (“EMS”) providers. Additionally, we have approximately 150 distributor customers worldwide, through which 
we indirectly serve over 50,000 customers.  

We  were  incorporated  in  1959  in  California  and  reincorporated  in  Delaware  in  1968.  Our  headquarters  and  sales  office  are 
located in Plano, Texas. Our design, marketing and engineering centers are located in Plano; Milpitas, California; San Jose, California; 
Taipei,  Taiwan;  Taoyuan  city,  Taiwan;  Zhubei  City,  Taiwan;  Jinan,  China;  Manchester,  United  Kingdom  (“U.K.”);  and  Neuhaus, 
Germany. We have two wafer fabrication facilities in Shanghai, China, one in Kansas City, Missouri, one in Manchester and one in 
Jinan. We also have assembly and test facilities located in Shanghai, Jinan, Chengdu, and Yangzhou, China as well as assembly and 
test facilities located in Hong Kong, Neuhaus and in Taipei. Additional engineering, sales, warehouse and logistics offices are located 
in Taipei; Hsinchu, Taiwan; Hong Kong; Manchester; Shanghai; Shenzhen, China; Seongnam-si, South Korea and Munich, Germany, 
with support offices located throughout the world.  

BUSINESS OUTLOOK  

Looking forward, we remain focused on achieving our goal of $1 billion in annual revenue with model gross margins of 35%. 
Acquisitions remain a key part of our growth strategy to reach our revenue goal. We have a solid pipeline of designs and expanded 
customer relationships across all regions and product lines. The success of our business depends on, among other factors, the strength 
of the global economy and the stability of the financial markets, our customers’ demand for our products, the ability of our customers 
to  meet  their  payment  obligations,  the  likelihood  of  customers  not  canceling  or  deferring  existing  orders,  and  the  strength  of 
consumers’ demand for items containing our products in the end-markets we serve. We believe the long-term outlook for our business 
remains generally favorable despite the uncertainties in the global economy as we continue to execute on the strategy that has proven 
successful  for  us  over  the  years.  See  “Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  - 
Business Outlook” in Part II, Item 7 and “Risk Factors – The success of our business depends on the strength of the global economy 
and  the  stability  of  the  financial  markets,  and  any  weaknesses  in  these  areas  may  have  a  material  adverse  effect  on  our  net  sales, 
operating results and financial condition.” in Part I, Item 1A of this Annual Report for additional information.   

PERICOM ACQUISITION 

On November 24, 2015, we completed our acquisition of Pericom Semiconductor Corporation (“Pericom”).  For the fiscal year 
ended June 27, 2015, Pericom reported net revenues of $128.8 million and net income of $11.8 million.  Pericom designs, develops 

- 1 - 

 
 
and markets high-performance integrated circuits (“ICs”) and frequency control products (“FCPs”) used in many of today’s advanced 
electronic systems. ICs include functions that support the connectivity, timing and signal conditioning of high-speed parallel and serial 
protocols that transfer data among a system’s  microprocessor,  memory and  various peripherals, such as displays and  monitors, and 
between interconnected systems. FCPs are electronic components that provide frequency references such as crystals and oscillators for 
computer, communication and consumer electronic products. Analog, digital and mixed-signal ICs, together with FCPs enable higher 
system  bandwidth  and  signal  quality,  resulting  in  better  operating  reliability,  signal  integrity,  and  lower  overall  system  cost  in 
applications such as notebook computers, servers, network switches and routers, storage area networks, digital TVs, cell phones, GPS 
and digital media players.  

Pursuant  to  the  Agreement  and  Plan  of  Merger  dated  as  of  September  2,  2015  (the  “Merger  Agreement”),  as  amended  on 
November 6, 2015, by Amendment No. 1 (the “Merger Agreement Amendment”), each outstanding share of common stock, without 
par value, of Pericom (other than shares owned by Pericom or certain of its affiliates or shares held by Pericom shareholders who have 
perfected  their  appraisal  rights  in  accordance  with  applicable  California  law)  was  automatically  converted  into  the  right  to  receive 
$17.75  in  cash  per  share,  without  interest.  The  aggregate  consideration  was  approximately  $403.2  million  including  the  value  of 
Pericom equity awards paid out or converted to Diodes equity awards pursuant to the Merger Agreement and the Merger Agreement 
Amendment.    The  aggregate  consideration  resulted  in  $54.3  million  of  goodwill.    These  preliminary  amounts  are  subject  to 
adjustment. 

SEGMENT INFORMATION AND ENTERPRISE-WIDE DISCLOSURES  

For financial reporting purposes, we operate in a single segment, standard semiconductor products, through our various design, 
manufacturing and distribution facilities. We sell product primarily through our operations in Asia, North America and Europe. We 
aggregate  our  products  in  a  single  segment  because  the  products  have  similar  economic  characteristics,  are  similar  in  production 
process  and  manufacturing  flow,  and  share  the  same  customers  and  target  end-equipment  markets.  See  Note  14  of  “Notes  to 
Consolidated Financial Statements” of this Annual Report for addition information.  

OUR INDUSTRY  

Semiconductors are critical components used in the manufacture of a broad range 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.  

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 assembly and test 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, we have historically operated our Shanghai manufacturing 
facilities at near full capacity, while at the same time expanding that capacity to meet our growth objectives. In 2011, we established 
an additional manufacturing facility for semiconductor assembly and test in Chengdu, China, which became fully production capable 
during the second half of 2015. Additionally, the Shanghai and Chengdu locations of our manufacturing operations provide us with 
access to a workforce at a relatively low overall cost base while enabling us to better serve our leading customers, many of which are 
located in Asia. In 2012, we acquired approximately 51% of the outstanding common stock of Eris Technology Corporation (“Eris”), 
primarily  to  obtain  its  automatic  manufacturing  capabilities  in  assembly  and  test  for  various  diode  products.  In  2013,  we  acquired 
BCD,  which  has  in-house  manufacturing  capabilities  in  China,  as  well  as  a  cost-effective  development  team  that  can  be  deployed 
across multiple product families. See “Risk Factors—During times of difficult market conditions, our fixed costs combined with lower 
net sales and lower profit margins may have a negative impact on our business, operating results and financial condition.” in Part I, 
Item 1A of this Annual Report for additional information.  

Integrated  packaging  expertise  –  Our  expertise  in  designing  and  manufacturing  innovative  and  proprietary  packaging 
solutions enables us to package a variety of different device functions into an assortment of packages ranging from miniature chip-
scale packaging to packages that integrate multiple separate discrete and/or analog chips into a single semiconductor product called an 
array. Our ability to design and manufacture multi-chip semiconductor solutions as well as advanced integrated devices provides our 
customers with products of equivalent functionality with fewer individual parts, and at lower overall cost, than alternative products. 
This  combination  of  integration,  functionality  and  miniaturization  makes  our  products  well  suited  for  high-volume  consumer 

- 2 - 

 
electronic  devices  such  as  LED  televisions,  LCD  panels,  set-top  boxes  and  consumer  portables  such  as  smartphones,  tablets  and 
notebooks.  

Broad  customer  base  and  diverse  end-markets  –  Our  customers  are  comprised  of  leading  OEMs  as  well  as  major  EMS 
providers. Overall, we serve over 250 direct customers worldwide and over 50,000 additional customers through our distributors. Our 
products are ultimately used in end-products in a number of markets served by our broad customer base, which we believe makes us 
less susceptible to market fluctuations driven by either specific customers or specific end-user applications.    

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

Management experience – The members of our executive team average over 30 years of industry experience, and the length of 
their service has created significant institutional insight into our markets, our customers and our operations. See “Risk Factors—We 
may  fail  to  attract  or  retain  the  qualified  technical,  sales,  marketing,  finance  and  management  personnel  required  to  operate  our 
business successfully, which could adversely affect  our business, operating results and financial condition.” in Part I, Item 1A of this 
Annual Report for additional information.  

OUR STRATEGY  

Our  strategy  is  to  continue  to  enhance  our  position  as  a  leading  global  designer,  manufacturer  and  supplier  of  high-quality 
application-specific  standard  semiconductor  products,  utilizing  our  innovative  and  cost-effective  assembly  and  test  (packaging) 
technology and leveraging our process expertise and design excellence to achieve above-market profitable growth.  

The principal elements of our strategy include the following:  

Continue to rapidly introduce innovative discrete, logic and analog semiconductor products – We intend to maintain our 
rapid pace of new product introductions, especially for high-volume, high-growth applications with short design cycles, such as LCD 
and  LED  televisions  and  panels,  set-top  boxes,  portables  such  as  smartphones,  tablets  and  notebooks  along  with  other  consumer 
electronics  and  computing  devices,  as  well  as  added  emphasis  on  products  for  the  LED  lighting  market  and  the  industrial  and 
automotive markets. During 2015, we continued to achieve many significant new design wins at OEMs. Although a design win from a 
customer does not necessarily guarantee future sales to that customer, we believe that continued introduction of new and well-defined 
product  solutions  is  critically  important  in  maintaining  and  extending  our  market  share  in  the  highly  competitive  semiconductor 
marketplace. See “Risk Factors – Obsolete inventories as a result of changes in demand for our products and change in life cycles of 
our products could adversely affect our business, operating results and financial condition.” in Part I, Item 1A of this Annual Report 
for additional information.  

Expand  our  available  market  opportunities  –  We  believe  we  have  many  paths  to  increasing  our  addressable  market 
opportunity.  From  a  product  perspective,  we  intend  to  continue  expanding  our  product  portfolio  by  developing  derivative  and 
enhanced  performance  devices  that  target  adjacent  markets  and  end-equipment.  We  will  continue  to  cultivate  new  and  emerging 
customers within our targeted markets, further increasing our already broad customer base. As we focus on new customers, we try to 
expand our product portfolio penetration within these new, as well as existing, customers. As we expand our extensive range of high 
power efficiency and small form factor packages, we plan to introduce new and existing product functions in these new packages to 
allow an even greater market range.  

Maintain  intense  customer  focus  – We intend to continue to strengthen and deepen our customer relationships. We believe 
that continued focus on customer service is important and will help to increase our net sales, operating performance and 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 further reduce our design cycle time in order to quickly provide our customers with innovative 
products.  Additionally,  to  support  our  customer-focused  strategy,  we  continue  to  expand  our  sales  force  and  field  application 
engineers,  particularly  in  Asia  and  Europe,  during  periods  of  growth.  See  “Risk  Factors  –  We  are  and  will  continue  to  be  under 
continuous pressure from our customers and competitors to reduce the price of our products, which could adversely affect our growth 
and profit margins.” in Part I, Item 1A of this Annual Report for additional information.

Enhance cost competitiveness – A key element of our success is our overall low-cost manufacturing 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. In 2011, we commenced the expansion of our capacity 
further by establishing an additional manufacturing facility for semiconductor assembly and test in Chengdu, China, that became fully 
production capable in the second half of 2015. Historically, we attempt to operate our Shanghai facilities at near full utilization rates in 
order to achieve meaningful economies of scale.  

Pursue selective strategic acquisitions – As part of our strategy to expand our semiconductor product offerings and to maximize 
our  market  opportunities,  we  may  acquire  technologies,  product  lines  or  companies  in  order  to  enhance  our  product  portfolio  and 
accelerate our new product offerings. During 2011, we acquired approximately 30% of the outstanding common stock of Eris, and during 
2012, we increased our ownership in Eris to approximately 51%. The product offering of Eris includes Schottky Diodes, TVS Diodes, 
Zener  Diodes,  Bridge  Diodes,  rectifiers  and  the  relevant  devices.  Also  in  2012,  we  completed  the  acquisition  of  Power  Analog 
Microelectronics, Inc. (“PAM”), a provider of advanced analog and high-voltage power ICs, whose product portfolio includes Class D 
audio amplifiers, DC-DC converters and LED backlighting drivers. In 2013, we acquired BCD which, with its established manufacturing 
and sales presence in Asia and a particularly strong local market position in China, offers us an even greater penetration of the consumer 
electronics,  computing  and  communications  markets.  In  2015,  we  acquired  Pericom  Semiconductor  Corporation.  Pericom  designs, 
develops and  markets high-performance ICs and FCPs used in  many of today’s advanced electronic systems. ICs include functions 
that  support  the  connectivity,  timing  and  signal  conditioning  of  high-speed  parallel  and  serial  protocols  that  transfer  data  among  a 
system’s microprocessor, memory and various peripherals, such as displays and monitors, and between interconnected systems. FCPs 
are  electronic  components  that  provide  frequency  references  such  as  crystals  and  oscillators  for  computer,  communication  and 
consumer electronic products. Analog, digital and mixed-signal ICs, together with FCPs enable higher system bandwidth and signal 
quality,  resulting  in  better  operating  reliability  and  signal  integrity,  and  lower  overall  system  cost  in  applications  such  as notebook 
computers, servers, network switches and routers, storage area networks, digital TVs, cell phones, GPS and digital media players.  

See  “Risk  Factors  –  Part  of  our  growth  strategy  involves  identifying  and  acquiring  companies.  We  may  be  unable  to  identify 
suitable  acquisition  candidates  or  consummate  desired  acquisitions  and,  if  we  do  make  any  acquisitions,  we  may  be  unable  to 
successfully  integrate  any  acquired  companies  with  our  operations,  which  could  adversely  affect  our  business,  operating  results  and 
financial condition” in Part I, Item 1A and Note 16 of “Notes to Consolidated Financial Statements” of this Annual Report for additional 
information.

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

CUSTOMERS  

We  serve  over  250  direct  customers  worldwide,  including  major  OEMs  and  EMS  providers.  Additionally,  we  have 
approximately 150 distributor customers worldwide, through which we indirectly serve over 50,000 customers. Our customers include: 
(i)  leading  OEMs  in  a  broad  range  of  industries,  such  as  Continental  AG,  Delta  Electronics,  Honeywell,  Osram,  Phillips,  Arris, 
Emerson, Hella, LG Electronics, Lenovo, Quanta Computer, Seagate, Sagem Communication, and Samsung Electronics; (ii) leading 
EMS providers, such as Celestica, Flextronics, Hon Hai Precision Industry, Inventec, Jabil Circuit, and Sanmina-SCI, who build end-
market  products  incorporating  our  semiconductors  for  companies  such  as  Google,  GoPro,  Cisco,  Dell,  EMC,  Intel,  Microsoft, 
Thompson, and Roche Diagnostics; and (iii) leading distributors such as Arrow, Avnet, Future Electronics, Rutronic, Yosun Industrial, 
DigiKey, and Zenitron.  

For the years 2015, 2014 and 2013, our OEM and EMS customers together accounted for 33%, 33% and 35%, respectively, of our net 
sales. The decrease in 2014 is due primarily to the fact that the majority of BCD net sales are to distributors. No customer accounted 
for 10% or more of our net sales in 2015, 2014 or 2013. In addition, for information concerning our business with related parties, see 
“Business - Certain Relationships and Related Party Transactions.”  

We believe that our close relationships  with our customers have provided us  with deeper insight into our customers’  product 
needs.  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. 
See  “Risk  Factors  –  Our  customers  require  our  products  to  undergo  a  lengthy  and  expensive  qualification  process  without  any 
assurance of product sales and demand to audit our operations from time to time.  A failure to qualify a product or a negative audit 
finding could adversely affect our net sales, operating results and financial condition.” in Part I, Item 1A of this Annual Report for 
additional information.  

We generally warrant that products sold to our customers will, at the time of shipment, be free from defects in workmanship and 
materials and conform to our approved specifications. Subject to certain exceptions, our standard warranty extends for a period of one 
year  from  the  date  of  shipment.  Warranty  expense  has  not  been  significant.  Generally,  our  customers  may  cancel  orders  on  short 
notice without incurring a penalty. See “Risk Factors – Our customer orders are subject to cancellation or modification usually with 
no penalty. High volumes of order cancellation or reduction in quantities ordered could adversely affect our operating results and 
financial condition” in Part I, Item 1A of this Annual Report for additional information.

Many  of  our  customers  are  based  in  Asia  or  have  manufacturing  facilities  in  Asia.  Net  sales  by  country  consist  of  sales  to 
customers in that country based on the country to which products are shipped. We report net sales based on “shipped to” customer 
locations as  we believe this best represents  where our customers’ business activities occur. For the year ended December 31, 2015, 
approximately 60%, 9%, 8%, 7%, 6%, 4% and 6% of our net sales were derived from China, United States (“U.S.”), Korea, Germany, 
Singapore, Taiwan, and all other markets, respectively, compared to 62%, 9%, 7%, 7%, 6%, 3% and 6% in 2014, respectively.  

SALES AND MARKETING  

We market and sell our products worldwide through a combination of direct sales and marketing personnel, independent sales 
representatives and distributors. We have direct sales personnel in the U.S., the U.K., France, Germany, Korea, Hong Kong, Taiwan 
and China. We also have independent sales representatives in the U.S., Asia, and Europe. In addition, we have distributors in the U.S., 
Asia, and Europe.  

As  of  December 31,  2015,  our  direct  global  sales  and  marketing  organization  consisted  of  approximately  400  employees 
operating out of 13 offices. We have sales and marketing offices or representatives in Taipei, Taiwan; Shanghai and Shenzhen, China; 
Gyeonggi, South Korea; and Munich, Germany; and we have regional sales offices in the U.S. As of December 31, 2015, we also had 
approximately 16 independent sales representative firms marketing our products.  

Our marketing group focuses on our product strategy, product development roadmap, 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  teams  to  align  our  product  development  roadmap.  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 global field application engineering and customer support organizations.  

Our  website,  www.diodes.com,  features  an  extensive  online  product  catalog  with  advanced  search  capabilities.  This,  coupled 
with a comprehensive competitor cross-reference search, facilitates quick and thorough product selection.  Our website also provides 
easy  access  to  our  worldwide  sales  contacts  and  customer  support  and  incorporates  a  distributor-inventory  check  to  provide 
component inventory availability.  

MANUFACTURING OPERATIONS AND FACILITIES  

We operate two assembly and test facilities located in Shanghai, China, one in Jinan, China, one in Neuhaus, Germany, one in 
Taipei,  Taiwan  and  one  in  Chengdu,  China  that  became  fully  production  capable  in  the  second  half  of  2015.  We  have  two  wafer 
fabrication facilities located in Shanghai, one in Kansas City, Missouri and one in Manchester, U.K. Our wafer fabrication facilities in 
Shanghai  include  two  150mm  wafer  fabrication  centers,  our  Kansas  City  facility  fabricates  125mm  and  150mm  wafers,  and  our 
Manchester facility fabricates 150mm wafers.  

In  2010,  we  announced  an  investment  agreement  with  the  Management  Committee  of  the  Chengdu  Hi-Tech  Industrial 
Development  Zone  (the  “CDHT”).  Under  this  agreement,  we  formed  a  joint  venture  with  a  Chinese  partner,  Chengdu  Ya  Guang 
Electronic Company Limited (“Ya Guang”), to establish a semiconductor assembly and test manufacturing facility in Chengdu, China. 
We  currently  own  95%  of  the  joint  venture.  The  CDHT  granted  the  joint  venture  a  50-year  land  lease,  provides  corporate  and 
employee tax incentives, tax refunds, subsidies and other financial support. This is a long-term, multi-year project that will provide us 
additional capacity as needed. As of December 31, 2015, we have invested approximately $120 million, primarily for infrastructure, 
buildings and equipment related capital expenditures.  

For  the  years  ending  December 31,  2015  and  2014,  our  total  capital  expenditures  were  approximately  $138  million  and  $59 

million, respectively. The majority of our capital expenditures are in China.  

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

- 6 - 

 
condition  could  be adversely  affected  if  we  are  unable  to  obtain  adequate  supplies  in  a  timely  manner.”  in  Part  I,  Item 1A  of  this 
Annual Report for additional information.  

Our corporate headquarters are located in a facility we own in Plano, Texas. We also lease or own properties around the world 
for  use  as  sales  and  administrative  offices,  research  and  development  centers,  manufacturing  facilities,  warehouses  and  logistics 
centers. The size or location of these properties can change from time to time based on our business requirements. See “Properties” in 
Part I, Item 2 of this Annual Report for additional information.  

BACKLOG  

The amount of backlog to be shipped during any period is dependent upon various factors, and orders are subject to cancellation 
or modification, usually with no penalty to the customer. Orders are generally booked from one month to greater than twelve months 
in  advance  of  delivery.  The  rate  of  booking  of  new  orders  can  vary  significantly  from  month  to  month.  We,  and  the  industry  as  a 
whole,  continue  to  experience  a  trend  towards  shorter  customer-requested  lead-times,  and  we  expect  this  trend  to  continue.  The 
amount of backlog at any date depends upon various factors, including the timing of the receipt of orders, fluctuations in orders of 
existing product lines, and the introduction of any new lines. Accordingly, we believe that the amount of our backlog at any date is not 
an  accurate  measure  of  our  future  sales.  We  strive  to  maintain  proper  inventory  levels  to  support our  customers’  just-in-time  order 
expectations.    Our  backlog  of  orders,  based  on  expected  ship  date,  was  $122  million  at  December  31,  2015  and  $130  million  at 
December 31, 2014. 

PATENTS, TRADEMARKS AND LICENSES  

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

particularly as they relate to our miniature and power efficient packaging technologies.  

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

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

market with a portfolio of standard linear and low dropout regulator products, among others.  

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

PowerDI and SBR are registered trademarks of Diodes Incorporated  

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

In 2012, we acquired PAM, a provider of advanced analog and high-voltage power ICs. PAM’s product portfolio includes Class 
D  audio  amplifiers,  DC-DC  converters  and  LED  backlighting  drivers,  which  has  strengthened  our  position  as  a  global  provider  of 
high-quality and high-efficiency, space-saving analog products by expanding our product portfolio with innovative “filter-less” digital 
audio amplifiers, application-specific power management ICs, as well as high-performance LED drivers and DC-DC converters.  

In 2013, we acquired BCD, a leading supplier of standard linear and power management devices. BCD has a product portfolio 
that includes AC/DC and DC/DC solutions for chargers and power adapters. BCD’s established presence in Asia, with a particularly 
strong  local  market  position  in  China,  offers  us  even  greater  participation  into  the  consumer  electronics,  computing  and 
communications end-markets.   

In 2015, we acquired Pericom. Pericom designs, develops and markets high-performance ICs and FCPs used in many of today’s 
advanced electronic systems. ICs include functions that support the connectivity, timing and signal conditioning of high-speed parallel 
and  serial  protocols  that  transfer  data  among  a  system’s  microprocessor,  memory  and  various  peripherals,  such  as  displays  and 
monitors, and between interconnected systems. FCPs are electronic components that provide frequency references such as crystals and 
oscillators for computer, communication and consumer electronic products. Pericom’s analog, digital and mixed-signal ICs, together 
with  our  FCPs  enable  higher  system  bandwidth  and  signal  quality,  resulting  in  better  operating  reliability  and  signal  integrity,  and 
- 7 - 

 
lower overall system cost in applications such as notebook computers, servers, network switches and routers, storage area networks, 
digital TVs, cell phones, GPS and digital media players. 

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

COMPETITION  

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

ENGINEERING AND RESEARCH AND DEVELOPMENT  

Our  engineering  and  research  and  development  groups  consist  of  applications,  circuit  design,  and  product  development 
engineers  who  assist  in  determining  the  direction  of  our  future  product  lines.  One  of  their  key  functions  is  to  work  closely  with 
market-leading customers to further refine, expand and improve our product portfolio within our target 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.  

Product development engineers work directly with our semiconductor circuit design and layout engineers to develop and design 
products  that  match  our  customers’  requirements.  We  have  the  capability  to  capture  the  customers’  electrical  and  packaging 
requirements  and  translate  those  requirements  into  product  specifications  which  can  then  be  designed  and  manufactured  to  support 
customers’ end-system applications.  

For  the  years  ended  December 31,  2015,  2014  and  2013,  our  investment  in  research  and  development  activities  was 

approximately $57 million, $52 million and $48 million, respectively, or approximately 7%, 6% and 6%, respectively, of net sales.  

EMPLOYEES  

As  of  December 31,  2015,  we  employed  7,695  employees  (including  approximately  1,000  temporary  labor  or  independent 
contractors).  6,674 of our employees were in Asia, 558 were in the U.S. and 463 were in Europe. None of our employees in Asia or 
the  U.S.  are  subject  to  a  collective  bargaining  agreement,  but  a  majority  of  our  employees  in  Europe  is  covered  by  local  labor 
agreements. We consider our relations with our employees to be satisfactory. See “Risk Factors – We may fail to attract or retain the 
qualified  technical,  sales,  marketing,  finance  and  management/executive  personnel  required  to  operate  our  business  successfully, 
which  could  adversely  affect our  business,  operating  results  and  financial  condition.”  in  Part  I,  Item 1A  of  this  Annual  Report  for 
additional information.  

ENVIRONMENTAL MATTERS  

We are subject to a variety of U.S. federal, state, local and foreign governmental laws, rules and regulations related to the use, 
storage, handling, discharge or disposal of certain toxic, volatile or otherwise hazardous chemicals used in our manufacturing process 
in  China,  the  U.S.  and  the  U.K.  where  our  wafer  fabrication  facilities  are  located,  and  in  China,  Taiwan  and  Germany  where  our 
assembly and test facilities are located. Any of these regulations could require us to acquire equipment or to incur substantial other 
costs to comply with environmental regulations or remediate problems. For the years ended December 31, 2015, 2014 and 2013, our 
capital  expenditures  for  environmental  controls  have  not  been  material.  As  of  December 31,  2015,  there  were  no  known 
environmental  claims  or  recorded  liabilities.  See  “Risk  Factors  –  We  are  subject  to  many  environmental  laws  and  regulations  that 

- 8 - 

 
could  result  in  significant  expenses  and  could  adversely  affect  our  business,  operating  results  and  financial  condition.”  in  Part  I, 
Item 1A of this Annual Report for additional information.  

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS  

We  conduct  business  with  two  related  companies:  Lite-On  Semiconductor  Corporation  and  its  subsidiaries  and  affiliates 
(collectively, “LSC”), and Nuvoton Technology Corporation and its subsidiaries and affiliates (collectively, “Nuvoton”). LSC owned 
approximately 17% of our outstanding Common Stock as of December 31, 2015. We conduct business with a significant company, 
Keylink International (B.V.I.) Inc. and its subsidiaries and affiliates (collectively, “Keylink”).  Keylink is our 5% joint venture partner 
in our two Shanghai assembly and test facilities.  In addition, Ya Guang is our 5% joint venture partner in our two Chengdu assembly 
and test facilities; however, we have no material transactions with Ya Guang.  

Raymond  Soong,  the  Chairman  of  the  Board  of  Directors,  is  also  the  Chairman  of  LSC  and  the  Chairman  of  Lite-On 
Technology Corporation (“LTC”), a significant shareholder of LSC. C.H. Chen, our former President and Chief Executive Officer and 
currently the Vice Chairman of the Board of Directors, is also Vice Chairman of LSC and a board member of LTC. Dr. Keh-Shew Lu, 
a member of our Board of Directors and our President and Chief Executive Officer, is also a board member of Nuvoton. In addition, 
L.P. Hsu, a member of our Board of Directors, is also a consultant to LTC and a supervisor of the board of Nuvoton.  

The Audit Committee of the Board of Directors reviews all related party transactions for potential conflict of interest situations 
on an ongoing basis. We believe that all related party transactions are on terms no less favorable to us than would be obtained from 
unaffiliated third parties. For more information concerning our relationships with LSC, Keylink and Nuvoton, see “Risk Factors – One 
of our external suppliers is also a related party. The loss  of this supplier could harm our business, operating results and financial 
condition.”  in  Part  I,  Item 1A  and  Note  13  of  “Notes  to  Consolidated  Financial  Statements”  of  this  Annual  Report  for  additional 
information.  

SEASONALITY  

Historically, our net sales have been affected by the cyclical nature of the semiconductor industry.   In addition, our net sales 
have been subject to some seasonal variation with weaker net sales in the first and fourth calendar quarters.  See Note 17 (unaudited)

RISKS RELATED TO OUR BUSINESS  

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

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

During times of difficult market conditions, our fixed costs combined with lower net sales and lower profit margins may have a 
negative impact on our business, operating results and financial condition.  

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

Downturns in the highly cyclical semiconductor industry or changes in end-market demand could adversely 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. 
From  time  to  time,  the  semiconductor  industry  experiences  order  cancellations  and  reduced  demand  for  products,  resulting  in 
significant net sales declines, due to excess inventories at end-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, which may harm our operating results and financial condition.  

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

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

The  semiconductor  industry  in  which  we  operate  is  highly  competitive.  We  expect  intensified  competition  from  existing 
competitors  and  new  entrants.  Competition  is  based  on  price,  product  performance,  product  availability,  quality,  reliability, 
- 10 - 

 
 
technological innovation and customer service. We compete in various markets with companies of various sizes, many of which are 
larger and have greater resources or capabilities as it relates to financial, marketing, distribution, brand name recognition, research and 
development, manufacturing and other resources than we have. As a result, they may be better able to develop new products, market 
their  products,  pursue  acquisition  candidates  and  withstand  adverse  economic  or  market  conditions.  Most  of  our  current  major 
competitors are broad line semiconductor manufacturers who often have a wider range of product types and technologies than we do. 
In  addition,  companies  not  currently  in  direct  competition  with  us  may  introduce  competing  products  in  the  future.  Some  of  our 
current  major  competitors  are  Fairchild  Semiconductor  Corporation,  Infineon  Technologies  A.G.,  NXP  Semiconductors  N.V.,  ON 
Semiconductor Corporation, Rohm Electronics USA, LLC, Toshiba Corporation and Vishay Intertechnology, Inc. We may not be able 
to compete successfully in the future, and competitive pressures may harm our business, operating results and financial condition.  

One  of  our  external  suppliers  is  also  a  related  party.  The  loss  of  this  supplier  could  harm  our  business,  operating  results  and 
financial condition.  

In  2015,  2014  and  2013,  LSC,  our  largest  stockholder,  accounted  for  approximately  2%,  3%,  and  4%,  respectively,  of  our 
silicon wafer supply, and 3%, 2% and 3%, respectively, of our finished goods supply.  The loss of LSC as a supplier could materially 
harm our business, operating results and financial condition.  

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

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

Our  wafer  fabrication  facilities  are  located  in  Shanghai,  China,  Kansas  City,  Missouri,  and  Manchester,  U.K.,  while  our 
manufacturing facilities in Shanghai, Taipei, Taiwan, Chengdu, China, Jinan, China, and Neuhaus, Germany, perform assembly and 
test functions. Any disruption of operations at these facilities could have a material adverse effect on our manufacturing efficiencies, 
operating results and financial condition.  

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

Prices  for  our  products  tend  to  decrease  over  their  life  cycle.  There  is  substantial  and  continuing  pressure  from  customers  to 
reduce the total cost of purchasing our products. To remain competitive and retain our customers and gain new ones, we must continue 
to reduce our costs through product and manufacturing improvements. We must also strive to minimize our customers’ shipping and 
inventory financing costs and to meet their other goals for rationalization of supply and production. Our net sales growth and profit 
margins will suffer if we cannot effectively continue to reduce our costs and keep our product prices competitive.  

Our customers require our products to undergo a lengthy and expensive qualification process without any assurance of product 
sales and may demand to audit our operations from time to time.  A failure to qualify a product or a negative audit finding could 
adversely affect our net sales, operating results and financial condition.  

Prior to purchasing our products, our customers may require our products to undergo an extensive qualification process, which 
involves  rigorous  reliability  testing.  This  qualification  process  may  continue  for  six  months  or  longer.  However,  qualification  of  a 
product by a customer does not ensure any sales of the product to that customer. In addition, we are focusing more on the automotive 
and industrial markets. These markets, automotive in particular, require higher quality standards.  Although we are working to ensure 
our  organization  and  products  meet  the  more  rigorous  quality  standards,  there  can  be  no  assurances  we  will  succeed.    Even  after 
successful  qualification  and  sales  of  a  product  to  a  customer,  a  subsequent  revision  to  the  product,  changes  in  the  product’s 
manufacturing process or the selection of a new supplier by us may require a re-qualification process, which may result in delayed net 
sales  and  excess  or  obsolete  inventory.  After  our  products  are  qualified,  it  can  take  an  additional  six  months  or  more  before  the 
customer  commences  volume  production  of  components  or  devices  that  incorporate  our  products.  Despite  these  uncertainties,  we 
devote substantial resources, including design, engineering, sales, marketing and management efforts, toward qualifying our products 
with  customers  in  anticipation  of  sales.  If  we  are  unsuccessful  or  delayed  in  qualifying  any  of  our  products  with  a  customer,  such 
- 11 - 

 
failure or delay would preclude or delay sales of such product to the customer, which may adversely affect our net sales, operating 
results and financial condition.  

In addition, from time to time, our customers  may demand an audit of our records, product  manufacturing, qualification, and 
packaging  processes,  business  practices  and  other  related  items  to  verify  that  we  have  complied  with  our  business  obligations, 
standard processes and procedures, product specifications and certain governing laws and regulations related to our business practices, 
and in accordance with the agreed terms and conditions of mutual business agreements.  If the audit shows any deficiency in any of 
these  categories,  our  customers  may  require  us  to  implement  extensive  protocols  to  remedy  the  deficiency,  assess  us  significant 
penalties, refuse shipments of our products, return existing inventory, cancel orders, or terminate our business relationship, each of 
which will adversely affect our net sales, operating results and financial condition. 

Our customer orders are subject to cancellation or modification usually with no penalty. High volumes of order cancellation or 
reduction in quantities ordered could adversely affect our net sales, operating results 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 immediate delivery 
to twelve months or more 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  customer-requested  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 purchase orders even though they  may 
ultimately be cancelled. If a significant number of purchase 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  net  sales,  operating  results  and  financial 
condition may suffer.  

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

A  disruption  in  production  at  our  manufacturing  facilities  could  have  a  material  adverse  effect  on  our  business.  Disruptions 
could  occur  for  many  reasons,  including  fire,  floods,  hurricanes,  typhoons,  droughts,  tsunamis,  volcanoes,  earthquakes,  disease  or 
other similar natural disasters, unplanned maintenance or other manufacturing problems, labor shortages, power outages or shortages, 
telecommunications failures, strikes, transportation interruption, government regulation, terrorism or other extraordinary events. Such 
disruptions  may cause direct  injury or damage to our employees and property and related internal controls  with  significant indirect 
consequences. Alternative facilities with sufficient capacity or capabilities may not be available, may cost substantially more or may 
take a significant time to start production, each of which could negatively affect our business and financial performance. If one of our 
key  manufacturing  facilities  is  unable  to  produce  our  products  for  an  extended  period  of  time,  our  sales  may  be  reduced  by  the 
shortfall  caused  by  the  disruption,  and  we  may  not  be  able  to  meet  our  customers’  needs,  which  could  cause  them  to  seek  other 
suppliers. Such disruptions could have an adverse effect on our operating results and financial condition.  

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

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

Products or technologies developed by other companies  may render our products or technologies obsolete or noncompetitive, 
and since we operate primarily in a narrower segment of the broader semiconductor industry, this may have a greater effect on us than 
it  would  if  we  were  a  broad-line  semiconductor  supplier  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 
- 12 - 

 
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 costs and expand our sales. We may not be able to accomplish these goals, which would adversely affect our net sales, 
market share, operating results and financial condition.  

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

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

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

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

We  may  be  subject  to  claims  of  infringement  of  third-party  intellectual  property  rights  or  demands  that  we  license  third-party 
technology, which could result in significant expense, reduction in our intellectual property rights and a negative impact on our 
business, operating results and financial condition.  

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 
technology  that  is  important  to  our  business  and  have  demanded,  and  may  in  the  future  demand,  that  we  license  their  patents  and 
technology.  Any  litigation to  determine the validity of allegations that our products infringe or  may infringe these rights, including 
claims arising through our contractual indemnification of our customers, or claims challenging the validity of our patents, regardless 
of its merit or resolution, could be costly and divert the efforts and attention of our management and technical personnel. We may not 
prevail in litigation given the complex technical issues and inherent uncertainties in intellectual property litigation. If litigation results 
in an adverse ruling, we could be required to:  

(cid:120)  pay substantial damages for past, present and future use of the infringing technology;  

(cid:120)  cease manufacture, use or sale of infringing products;  

(cid:120)  discontinue the use of infringing technology;  

(cid:120)  expend significant resources to develop non-infringing technology;  

(cid:120)  pay substantial damages to our customers or end-users to discontinue use or replace infringing technology with non-infringing 

technology;  

- 13 - 

 
(cid:120)  license technology from the third party claiming infringement, which license may not be available on commercially reasonable 

terms, or at all; or  

(cid:120)  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,  manufacturing  services,  product  and  process 
development,  parts  and  equipment,  as  well  as  finished  products  from  other  manufacturers,  and  our  reputation  with  customers, 
operating  results  and  financial  condition  could  be  adversely  affected  if  we  are  unable  to  obtain  adequate  supplies  in  a  timely 
manner.  

Our manufacturing operations depend upon obtaining adequate supplies of raw materials, manufacturing services, product and 
process development, parts and equipment on a timely basis from third parties. In some instances, a supplier may be our sole-source 
supplier.    Our  operating  results  could  be  adversely  affected  if  we  are  unable  to  obtain  adequate  supplies  of  raw  materials, 
manufacturing services, product and process development, parts and equipment in a timely manner or if the costs charged to us 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. In addition, we may be subject to 
quality claims from customers  who purchased goods from  companies before  we acquired those companies.  Any interruption in, or 
change  in  quality  of,  the  supply  of  raw  materials,  manufacturing  services,  product  and  process  development,  parts  or  equipment 
needed to manufacture our products could adversely affect our reputation with customers, operating results and financial condition.  

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

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

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

(cid:120)  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:120)  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:120)  the need for skills and techniques that are outside our traditional core expertise;  

(cid:120)  less flexibility in shifting manufacturing or supply sources from one region to another;  

(cid:120)  even  when  independent  suppliers  offer  lower  prices,  we  may  continue  to  source  wafers  from  our  captive  manufacturing 

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

(cid:120)  difficulties developing and implementing a successful research and development team; and  

(cid:120)  difficulties developing, protecting, and gaining market acceptance of, our proprietary technology.  

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

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

A significant part of our growth strategy involves acquiring companies. For example, (i) in 2000, we acquired FabTech, Inc., a 
wafer fabrication company, in order to have our own wafer manufacturing capabilities, (ii) in 2006, we acquired Anachip Corp. as an 
entry into the analog market, (iii) in 2006, we acquired the net operating assets of APD Semiconductor, Inc., (iv) in 2008, we acquired 
Zetex plc., (v) in 2012, we acquired over 50% of the outstanding common stock of Eris Technology Corporation, (vi) also in 2012, we 
acquired Power  Analog Microelectronics, Inc., (vii) in 2013,  we acquired BCD Semiconductor Manufacturing  Limited and (viii) in 
2015, we acquired Pericom Semiconductor Corporation. In addition, from time to time, we may be in various stages of discussions 
with  potential  acquisition  targets  as  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, operating results and financial condition. In addition, we may not realize all of the benefits we 
anticipate from any such acquisitions. Some of the risks that may affect our ability to integrate or realize any anticipated benefits from 
acquisitions that we may make include those associated with:  

(cid:120)  unexpected losses of key employees or customers of the acquired company;  

(cid:120)  bringing the acquired company’s standards, processes, procedures and controls into conformance with our operations;  

(cid:120)  coordinating our new product and process development;  

(cid:120)  hiring additional management and other critical personnel;  
(cid:120)  increasing the scope, geographic diversity and complexity of our operations;  

(cid:120)  difficulties in consolidating facilities and transferring processes and know-how;  

(cid:120)  difficulties in reducing costs of the acquired entity’s business;  

(cid:120)  diversion of management’s attention from the management of our business; and  

(cid:120)  adverse effects on existing business relationships with customers.  

We  are  subject  to  litigation  risks,  including  securities  class  action  litigation,  which  may  be  costly  to  defend  and  the  outcome of 
which is uncertain and could adversely affect our business and financial condition.  

All  industries,  including  the  semiconductor  industry,  are  subject  to  legal  claims,  with  and  without  merit,  including  securities 
class  action  litigation  that  may  be  particularly  costly  and  which  may  divert  the  attention  of  our  management  and  our  resources  in 
general. We are involved in a variety of legal matters, most of which we consider either routine matters that arise in the normal course 
of business or immaterial for our aggregate business operations. These routine matters typically fall into broad categories such as those 
involving suppliers and customers, employment and labor, and intellectual property. We believe it is unlikely that the final outcome of 
these legal claims will have a material adverse effect on our financial position, operating results or cash flows. However, defense and 
settlement costs can be substantial, even with respect to claims that we believe have no merit. Due to the inherent uncertainty of the 
litigation process, the resolution of any particular legal claim or proceeding could adversely affect our business, operating results and 
financial condition.  

From  time  to  time,  we  have  been,  or  may  in  the  future  be,  involved  in  securities  litigation  or  litigation  arising  from  our 
acquisitions. We can provide  no assurance as to the outcome of any such litigation  matter in  which  we are a party.  These types of 
matters  are  costly  to  defend  and  even  if  resolved  in  our  favor,  could  have  a  material  adverse  effect  on  our  business,  financial 
condition,  operating  results  and  cash  flow.  Such  litigation  could  also  substantially  divert  the  attention  of  our  management  and  our 
resources in general. Uncertainties resulting from the initiation and continuation of securities or other litigation could harm our ability 
to obtain credit and financing for our operations and to compete in the marketplace. Because the price of our Common Stock has been, 
and  may continue to be, volatile,  we can provide no assurance that securities litigation  will not be filed against  us in the future. In 
addition, we can provide no assurance that our past or future acquisitions will not subject us to additional litigation. See Part I, Item 3 
“Legal Proceedings” of this Annual Report for more information on our legal proceedings.  

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

We are subject to a variety of U.S. federal, state, local and foreign governmental laws, rules and regulations related to the use, 
storage, handling, discharge or disposal of certain toxic, volatile or otherwise hazardous chemicals used in manufacturing our products 

- 15 - 

 
throughout  the  world.  Some  of  these  regulations  in  the  U.S.  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  operating  results.  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, operating results and financial condition. Our operations affected by such requirements include, among 
others: the disposal of wastewater containing residues from our manufacturing operations through publicly operated treatment works 
or sewer systems, and which may be subject to volume and chemical discharge limits and may also require discharge permits; and the 
use, storage and disposal of materials that may be classified as toxic or hazardous. Any of these may result in, or may have resulted in, 
environmental conditions for which we could be liable.  

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

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

Our products are typically sold at prices that are an insignificant portion of the overall value of the equipment or other goods in 
which they are incorporated. For example, our products that are incorporated into a television may be sold for several cents, whereas 
the television maker might sell the television for several hundred dollars. Although we maintain rigorous quality control systems, we 
receive warranty claims and product liability 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 net sales 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 operating results 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. We  may choose not to carry 
liability insurance, may not have sufficient insurance coverage, or may not have sufficient resources, to satisfy all possible warranty 
claims and product liability claims. In addition, any perception that our products are defective would likely result in reduced sales of 
our products, loss of customers and harm to our business, reputation, operating results and financial condition.  

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

Our future success depends, in part, upon our ability to attract and retain highly qualified technical, sales, marketing, finance 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, finance and  managerial employees or be successful in attracting, 
assimilating or retaining other highly qualified technical, sales, marketing, finance and managerial/executive personnel in the future. 
For example, we have faced, and continue to face, intense competition for qualified technical and other personnel in China, where our 
assembly and test 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  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, operating results and financial condition could be materially and adversely 
affected.  

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

Our ability to successfully grow our business 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 

- 16 - 

 
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 profitable growth, which could adversely affect our business, operating results and financial condition.  

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

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

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

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

We are subject to interest rate risk that could have an adverse effect on our cost of working capital and interest expenses, which 
could adversely affect our business, operating results and financial condition.  

We  currently  have  a  U.S.  banking  credit  facility  under  which  we  may  draw  up  to  $500  million  with  the  possibility  of  an 
additional $200 million. A rise in interest rates could have an adverse impact upon our cost of working capital and our interest expense. 
As of December 31, 2015, an increase of 1% in interest rates on our outstanding debt would increase our annual interest rate expense 
by approximately $5 million. 

We may have a significant amount of debt with various financial institutions worldwide. Any indebtedness could adversely affect 
our business, operating results, financial condition and our ability to meet payment obligations under such debt.  

We may have a significant amount of debt and substantial debt service requirements on our borrowings, including our credit 
facilities  with  various  financial  institutions  worldwide.  As  of  December  31,  2015  $465  million  was  outstanding  under  our  U.S. 
banking  credit  facility.  In  addition,  we  have  short-term  foreign  credit  facilities  with  borrowing  capacities  of  approximately 
$84 million and with $1 million used for import and export guarantees. We have approximately $2 million of foreign long-term debt.   

A significant amount of debt could have significant consequences on our future operations, including:  

(cid:120)  making it more difficult for us to meet our payment and other obligations under our outstanding debt;  

(cid:120)  resulting  in  an  event  of  default  if  we  fail  to  comply  with  the  financial  and  other  restrictive  covenants  contained  in  our  debt 
agreements, which event of default could result in all of our debt becoming immediately due and payable and, in the case of an 
event of default under our secured debt could permit the lenders to foreclose on our assets securing that debt;  

(cid:120)  reducing the availability of our cash flow to fund working capital, capital expenditures, acquisitions and other general corporate 

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

(cid:120)  subjecting us to the risk of increased sensitivity to interest rate increases on our indebtedness with variable interest rates;  

(cid:120)  limiting our flexibility in planning for, or reacting to, and increasing our vulnerability to, changes in our business, the industry in 

which we operate and the general economy; and  

(cid:120)  placing us at a competitive disadvantage compared to our competitors that have less debt or are less leveraged.  

- 17 - 

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

ability to meet our payment obligations under our debt.  

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

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

Our ability to comply with the U.S. banking credit facility may be affected by events beyond our control, including prevailing 
economic, financial and industry conditions, and are subject to the risks stated in this section of the Annual Report. The breach of any 
of these covenants or restrictions could result in an event of default under the facility.  An event of default under the facility  would 
permit the lenders under the facility to declare all amounts owed under such facility to be immediately due and payable in full. Upon 
acceleration of our indebtedness, we may be unable to repay the accelerated amount of principal and interest on the credit facilities 
that would then be due. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Financial 
Condition-Debt instruments” in Part II, Item 7 of this Annual Report for additional information.  

Our business benefits from certain Chinese government incentives. Expiration of, or changes to, these incentives could adversely 
affect our operating results and financial condition.  

The  Chinese  government  has  provided  various  incentives  to  technology  companies,  including  our  manufacturing  facilities 
located  in  Shanghai  and  Chengdu,  China,  in  order  to  encourage  development  of  the  high-tech  industry.  These  incentives  include 
reduced tax rates and other measures. As a result, we are entitled to a preferential enterprise income tax rate of 15% so long as our 
manufacturing  facilities  continue  to  maintain  their  High  and  New  Technology  Enterprise  (“HNTE”)  status.  One  of  our  Shanghai 
manufacturing facilities was approved for HNTE status for the tax years 2011-2013. For 2014 and future years, this facility no longer 
qualifies  for  HNTE  status  and,  therefore,  all  of  its  income  will  be  taxed  at  the  statutory  tax  rate  of  25%.  Our  other  Shanghai 
manufacturing  facility  has  been  approved  for  HNTE  status  for  the  tax  years  2015-2017.  In  addition,  one  of  our  wafer  fabrication 
facilities and one research and development facility located in Shanghai have been approved for HNTE status for the tax years 2014-
2016.  HNTE  qualification  requires  metrics  based  on  China  research  and  development  expenditures  as  well  as  research  and 
development headcount and overall college-degreed headcount.  Any prior years that have already been approved are subject to audit 
requirements. If we were to no longer meet the HNTE requirements, our statutory tax rate for our approved Shanghai assembly and 
test facility and wafer fabrication facility would increase to 25% for any period in which an audit shows we were not compliant, which 
could adversely affect our operating results and financial condition. 

In connection with our joint venture in Chengdu, China, we have qualified for tax incentives offered in the Go West Initiative 
(“Go West”), where companies are entitled to a preferential income tax rate of 15% for doing business in western China. If we were to 
no longer meet the Go West requirements, our statutory tax rate for this joint venture would increase to 25%, which could adversely 
affect our operating results and financial condition. 

The impact of our HNTE and Go West status, collectively called tax holidays, decreased our tax expense by approximately $3 
million,  $2  million  and  $2  million  for  the  years  ended  December 31,  2015,  2014  and  2013,  respectively.  The  benefit  of  the  tax 
holidays  on  both  basic  and  diluted  earnings  per  share  for  the  fiscal  year  ended  December 31,  2015  was  approximately  $0.06.  The 
benefit of the tax holidays on both basic and diluted earnings per share for both the fiscal years ended December 31, 2014 and 2013 
was approximately $0.05. 

We  operate a  global business  through  numerous  foreign  subsidiaries,  and  there  is  a  risk  that  tax  authorities  will  challenge  our 
transfer  pricing  methodologies  or  legal  entity  structures,  which  could  adversely  affect  our  operating  results  and  financial 
condition.  

We  conduct  operations  worldwide  through  our  foreign  subsidiaries  and  are,  therefore,  subject  to  complex  transfer  pricing 
regulations in the jurisdictions in which we operate. Transfer pricing regulations generally require that, for tax purposes, transactions 
between related parties be priced on a basis that would be comparable to an arm’s length transaction between unrelated parties. There 
is uncertainty and inherent subjectivity in complying with these rules. To the extent that any foreign tax authorities disagree with our 

- 18 - 

 
transfer  pricing  policies,  we  could  become  subject  to  significant  tax  liabilities  and  penalties.  Based  on  our  current  knowledge  and 
probability assessment of potential outcomes, we believe that we have provided for all tax exposures. However, the ultimate outcome 
of a tax examination could differ materially from our provisions and could have a material adverse effect on our business, financial 
condition, operating results and cash flows.  

Our  legal  organizational  structure  could  result  in  unanticipated  unfavorable  tax  or  other  consequences  which  could  have  a 
material adverse effect on our financial condition and operational results. In some countries, we maintain multiple entities for tax or 
other purposes. Changes in tax laws, regulations, future jurisdictional profitability of us and our subsidiaries, and related regulatory 
interpretations  in  the  countries  in  which  we  operate  may  impact  the  taxes  we  pay  or  tax  provision  we  record,  which  could  have  a 
material  adverse  effect  on  our  operating  results.  In  addition,  any  challenges  to  how  our  entities  are  structured  or  realigned  or  their 
business purpose by taxing authorities could result in us becoming subject to significant tax liabilities and penalties which could have 
a material adverse effect on our business, financial condition, operating results and cash flows.  

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

Certain of our employees in the U.K. participate in a company-sponsored defined benefit plan, which is closed to new entrants 
and is frozen with respect to future benefit accruals. The retirement benefit is based on the final average compensation and service of 
each  eligible  employee.  In  accounting  for  these  plans,  we  are  required  to  make  actuarial  assumptions  that  are  used  to  calculate  the 
earning  value of the related assets,  where applicable, and liabilities and the amount of expenses to be recorded in our consolidated 
financial  statements.  Assumptions  include,  but  are  not  limited  to,  the  expected  return  on  plan  assets,  discount  rates,  and  mortality 
rates. While we believe the underlying assumptions under the projected unit credit method are appropriate, the carrying value of the 
related assets and liabilities and the actual amount of expenses recorded in the consolidated financial statements could differ materially 
from the assumptions used.  

Changes in actuarial assumptions for our defined benefit plan could increase the volatility of the plan’s asset value, require us to 
increase cash contributions to the plan and have a negative impact on our cash flows, operating results and financial condition.  

The assets of our defined benefit pension plan (the “plan”) in the U.K. provide pensions to employees and former employees.  
The  plan’s  assets  consist  primarily  of  high-quality,  corporate  bonds  and  stocks  traded  on  the  London  Stock  Exchange  and  are 
determined, from time to time, based on their fair market value.  The plan’s obligation to pay pensions is estimated by using actuarial 
assumptions.  To  the  extent  that  the  plan’s  assets  are  not  sufficient  to  meet  the  estimated  amount  of  the  plan’s  obligations,  further 
funding  of  the  plan  will  be  required  by  the  plan’s  sponsoring  employers,  Diodes  Zetex  Limited  and  Diodes  Zetex  Semiconductors 
Limited, over an agreed upon deficit recovery period. 

As of December 31, 2015, the benefit obligation of the plan was approximately $145 million and the total assets in such plan 
were approximately $116 million. Therefore, the plan was underfunded by approximately $29 million. The difference between plan 
obligations and assets, or the funded status of the plan, is a significant factor in determining the net periodic benefit costs of the plan 
and the ongoing funding requirements of the plan.  

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

During the second quarter of 2012, we adopted a payment plan with the trustees of the defined benefit plan, under which we 
would pay approximately British Pound (“GBP”) 2 million (approximately $3 million based on a USD:GBP exchange rate of 1.6:1) 
every  year  from 2012 through 2019. In the  first quarter of 2015, based on the pension  deficit,  we adopted (as required every three 
years) an amended payment plan in which we will pay approximately GBP 2 million (approximately $3 million based on a USD:GBP 
exchange rate of 1.6:1) annually through 2030. This revised payment plan resulted in an increase of total required contributions from 
GBP 8 million to GBP 33 million (approximately $46 million). If we fail to reach an agreement with the trustees, as we are required to 
do  every  three  years,  the  Pension  Regulator  in  the  U.K.  could  impose  contributions  on  Diodes  Zetex  Limited  or  Diodes  Zetex 
Semiconductors Limited, or in limited circumstances could require financial support to be provided to the plan from entities connected 
or associated with Diodes Zetex Limited or Diodes Zetex Semiconductors Limited. Furthermore, Diodes Zetex Limited and Diodes 
Zetex  Semiconductors  Limited  remain  ultimately  liable  to  fully  fund  the  plan  regardless  of  any  failure  to  agree  upon  future 
contributions in respect of a particular actuarial valuation, i.e., if either the plan or those companies were wound up, a debt equal to 

- 19 - 

 
each company’s share of the entire outstanding deficit at that time (calculated on a statutory conservative basis) would be owed by the 
relevant company. This could have a material adverse effect on our cash flows, operating results and financial condition.   

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

Certain of our customers and suppliers require us to agree to comply with the Electronic Industry Code of Conduct (“EICC”) or 
their own codes of conduct, which may include detailed provisions on labor, human rights, health and safety, environment, corporate 
ethics and management systems. Certain of these provisions are not requirements under the laws of the countries in which we operate 
and may be burdensome to comply with on a regular basis. Moreover, new provisions may be added or material changes may be made 
to  any  these  codes  of  conduct,  and  we  may  have  to  promptly  implement  such  new  provisions  or  changes,  which  may  substantially 
further increase the cost of our business, be burdensome to implement and adversely affect our operational efficiencies and operating 
results. If we violate any such codes of conduct, we may lose further business with the customer or supplier and, in addition, we may 
be  subject  to  fines  from  the  customer  or  supplier.  While  we  believe  that  we  are  currently  in  compliance  with  our  customers  and 
suppliers’ codes of conduct, there can be no assurance that, from time to time, if any one of our customers and suppliers audits our 
compliance  with  such  code  of  conduct,  we  would  be  found  to  be  in  full  compliance.  A  loss  of  business  from  these  customers  or 
suppliers could have a material adverse effect on our business, operating results and financial condition.  

Compliance with government regulations and customer demands regarding the use of “conflict minerals” may result in increased 
costs and may have a negative impact on our business, operating results and financial condition.  

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 imposes new disclosure requirements regarding the 
use of certain minerals, which are mined from the Democratic Republic of Congo and adjoining countries, known as conflict minerals. 
When these new requirements are fully implemented, they could affect the pricing, sourcing and availability of minerals used in the 
manufacture of semiconductor devices (including our products). We are incurring additional costs associated with complying with the 
disclosure  requirements,  such  as  costs  related  to  determining  the  source  of  any  conflict  minerals  used  in  our  products.  Our  supply 
chain is complex, and  we  may be unable to  verify  the origins  for all  metals  used in our products. Customers  may demand  that the 
products they purchase be free of conflict minerals. Therefore, we may encounter challenges with our customers and stockholders if 
we are unable to certify that our products are conflict free. This requirement could affect the sourcing and availability of products we 
purchase from suppliers. This may reduce the number of suppliers that may be able to provide conflict-free products, and may affect 
our ability to obtain products in sufficient quantities to meet customer demand or at competitive prices.  

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

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

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

result in significant asset impairment charges in the future.  

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

Effective internal controls are necessary  for us to produce reliable financial reports and are important in our effort to prevent 
financial fraud. We are required to periodically evaluate the effectiveness of the design and operation of our internal controls. These 
evaluations  may  result  in  the  conclusion  that  enhancements,  modifications  or  changes  to  our  internal  controls  are  necessary  or 
desirable. While management evaluates the effectiveness of our internal controls on a regular basis, these controls may not always be 
effective.  There  are  inherent  limitations  on  the  effectiveness  of  internal  controls,  including  collusion,  management  override,  and 
failure of human judgment. Because of this, control procedures are designed to reduce rather than eliminate business risks. If we fail to 
maintain  an  effective  system  of  internal  controls  or  if  management  or  our  independent  registered  public  accounting  firm  were  to 
- 20 - 

 
discover material weaknesses in our internal controls, we may be unable to produce reliable financial reports or prevent fraud, which 
could harm our financial condition and operating results, and could result in a loss of investor confidence and a decline in our stock 
price.  

Our management certification and auditor attestation regarding the effectiveness of our internal control over financial reporting 
as of December 31, 2015 excluded the operations of Pericom. If we are not able to integrate Pericom operations into our internal 
control over financial reporting, our internal control over financial reporting may not be effective. 

Section 404 of the Sarbanes-Oxley Act (“SOX 404”) requires us to furnish a management certification and auditor attestation 
regarding the effectiveness of our internal control over  financial  reporting.  As a public  company,  we are required to  report, among 
other  things,  control  deficiencies  that  constitute  a  “material  weakness”  or  changes  in  internal  control  that  materially  affect,  or  are 
reasonably  likely  to  materially  affect,  internal  control  over  financial  reporting.  A  “material  weakness”  is  a  deficiency,  or  a 
combination  of  deficiencies,  in  internal  control  over  financial  reporting  such  that  there  is  a  reasonable  possibility  that  a  material 
misstatement of the registrant’s annual or interim financial statements will not be prevented or detected on a timely basis. 

Complying with SOX 404 is time consuming and costly. The integration of Pericom operations into our internal control over 
financial  reporting  will  require  additional  time  and  resources  from  our  management  and  other  personnel  and  may  increase  our 
compliance costs.  

Failure to comply with SOX 404, including a delay in or failure to successfully integrate Pericom operations into our internal 
control over financial reporting, or the report by us of a material weakness may cause investors to lose confidence in our consolidated 
financial  statements,  and  the  trading  price  of  our  Common  Stock  may  decline.  If  we  fail  to  remedy  any  material  weakness,  our 
financial statements may be inaccurate, our access to the capital markets may be restricted and the trading price of our Common Stock 
may decline. 

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

Terrorist  attacks,  or  threats  or  occurrences  of  other  terrorist  or  related  activities,  whether  in  the  U.S.  or  internationally,  may 
affect the markets in which our Common Stock trades, the markets in which we operate and our profitability. Future terrorist or related 
activities could affect our domestic and international sales, disrupt our supply chains and impair our ability to produce and deliver our 
products. Such activities could affect our physical facilities or those of our suppliers or customers. Such terrorist attacks could cause 
seaports or airports, to or through which we ship, to be shut down, thereby preventing the delivery of raw materials and finished goods 
to or from our manufacturing facilities in China, Taiwan and Germany and our wafer fabrication facilities in China, the U.S. and the 
U.K., 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  negatively  affect  our  future  operating  results  and 
financial condition.  

System  security  risks,  data  protection  breaches,  cyber-attacks  and  other  related  cybersecurity  issues  could  disrupt  our  internal 
operations,  and  any  such  disruption  could  reduce  our  expected  net  sales,  increase  our  expenses,  damage  our  reputation  and 
adversely affect our stock price.  

Experienced  computer  programmers  and  hackers  may  be  able  to  penetrate  our  security  controls  and  misappropriate  or 
compromise  our  confidential  information  or  that  of  third  parties,  create  system  disruptions  or  cause  shutdowns.  Computer 
programmers and hackers also may be able to develop and deploy viruses, worms and other malicious software programs that attack 
our websites, products or otherwise exploit any security vulnerabilities of our websites and products. The costs to us to eliminate or 
alleviate cyber or other security problems, bugs,  viruses,  worms,  malicious software programs and security  vulnerabilities could be 
significant,  and  our  efforts  to  address  these  problems  may  not  be  successful  and  could  result  in  interruptions,  delays,  cessation  of 
service, extortionate demands to decrypt files and loss of existing or potential customers that may impede our sales, manufacturing, 
distribution or other critical functions and materially adversely affect our operating results, stock price and reputation.  

We manage and store various proprietary information and sensitive or confidential data relating to our business and third party 
business. Breaches of our security measures or the accidental loss, inadvertent disclosure or unapproved dissemination of proprietary 
information  or  sensitive  or  confidential  data  about  us  or  our  partners  or  customers,  including  the  potential  loss,  encryption  or 
disclosure  of  such  information  or  data  as  a  result  of  fraud,  trickery  or  other  forms  of  deception,  could  expose  us,  our  partners  and 
customers or the individuals affected to a risk of loss or misuse of this information, extortionate demands to decrypt files, result in 
litigation  and  potential  liability  for  us,  damage  our  brand  and  reputation  or  otherwise  harm  our  business.  In  addition,  the  cost  and 
operational consequences of implementing  further data protection  measures could be significant. Delayed  sales,  significant costs or 
lost  customers  resulting  from  these  system  security  risks,  data  protection  breaches,  cyber-attacks  and  other  related  cyber-security 
issues could materially adversely affect our operating results, stock price and reputation.

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 in China. In each of the years ended 2015, 2014 and 2013, our Asian and European 
subsidiaries represented approximately 90% 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:120)  changes in, or impositions of, legislative or regulatory requirements, including income tax or value added tax laws in the U.S. 

and in the countries in which we manufacture or sell our products;  

(cid:120)  compliance with trade or other laws in a variety of jurisdictions;  
(cid:120)  trade restrictions, transportation delays, work stoppages, and economic and political instability;  

(cid:120)  changes in import/export regulations, tariffs and freight rates;  

(cid:120)  difficulties in collecting receivables and enforcing contracts;  

(cid:120)  currency exchange rate fluctuations;  

(cid:120)  restrictions on the transfer of funds from foreign subsidiaries to the U.S.;  
(cid:120)  the possibility of international conflict, particularly between or among China, the U.K., Germany, Taiwan and the U.S.;  

(cid:120)  legal, regulatory, political and cultural differences among the countries in which we do business;  

(cid:120)  longer customer payment terms; and  

(cid:120)  changes in U.S. or foreign tax regulations.  

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

We have a significant portion of our assets in mainland China, U.K., Germany, Hong Kong and Taiwan. Our ability to operate 
in  these  countries  may  be  adversely  affected  by  changes  in  those  jurisdictions’  laws  and  regulations,  including  those  relating  to 
taxation, including, but not limited to income tax and value added tax, import and export tariffs, environmental regulations, land use 
rights,  property  and  other  matters.  In  addition,  our  operating  results  and  financial  performance  are  subject  to  the  economic  and 
political situations. We believe that our operations are in compliance with all applicable legal and regulatory requirements. However, 
the central or local governments of these jurisdictions may impose new, stricter regulations or interpretations of existing regulations 
that would require additional expenditures and efforts on our part to ensure our compliance with such regulations or interpretations.  

Changes in the political environment or government policies in those jurisdictions could result in revisions to laws or regulations 
or their interpretation and enforcement, increased taxation, restrictions on imports, import duties or currency revaluations. In addition, 
a significant destabilization of relations between or among China, the U.K., Germany, Hong Kong, Taiwan and the U.S. 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 U.S. could have an adverse 
impact upon our ability to transact business in these jurisdictions and to generate profits.  

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

We believe that an increase in demand in China for electronic devices that include our products will be an important factor in 
our  future  growth.  Continuing  weakness  in  the  Chinese  economy  could  result  in  a  decrease  in  demand  for  electronic  devices 
containing our products and, thereby, materially and adversely affect our business, operating results and prospects.  

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

We have a significant portion of our manufacturing capacity in mainland China. In addition, in 2015 approximately 60% of our 
total sales were shipped to customers in China. In recent years, the Chinese economy has experienced periods of rapid expansion and 

- 22 - 

 
wide  fluctuations  in  the  rate  of  inflation.  In  response  to  these  factors,  the  Chinese  government  has,  from  time  to  time,  adopted 
measures to regulate growth and contain inflation, including measures designed to restrict credit or control prices. Such actions in the 
future  could  increase  the  cost  of  doing  business  in  China  or  decrease  the  demand  for  our  products  in  China  and,  thereby,  have  a 
material adverse effect on our business, operating results and prospects.  

We could be adversely affected by violations of the United States’ Foreign Corrupt Practices Act, the U.K.’s Bribery Act 2010 and 
similar worldwide anti-bribery laws.  

The United States’ Foreign Corrupt Practices Act (“FCPA”), the United Kingdom’s Bribery Act 2010 (the “U.K. Bribery Act”) 
and  similar  anti-bribery  laws  in  other  jurisdictions  generally  prohibit  companies  and  their  intermediaries  from  making  improper 
payments to government officials for the purpose of obtaining or retaining business. Our policies mandate compliance with these anti-
bribery  laws.  We  operate  in  many  parts  of  the  world  that  may  have  experienced  governmental  corruption  to  some  degree  and,  in 
certain  circumstances,  strict  compliance  with  anti-bribery  laws  may  conflict  with  local  customs  and  practices.  We  train  our  staff 
concerning  FCPA,  the  U.K.  Bribery  Act  and  related  anti-bribery  laws.  We  have  established  procedures  and  controls  to  monitor 
internal  and  external  compliance.  There  can  be  no  assurance  that  our  internal  controls  and  procedures  always  will  protect  us  from 
reckless or criminal acts committed by our employees or agents. If we are found to be liable for FCPA, the U.K. Bribery Act and other 
anti-bribery law violations (either due to our own acts or inadvertence, or due to the acts or inadvertence of others), we could incur 
criminal or civil penalties or other sanctions, which could have a material adverse effect on our business and operating results.  

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

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

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

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

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

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

- 23 - 

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

We  intend  to  permanently  reinvest  overseas  all  earnings  from  foreign  subsidiaries,  except  to  the  extent  such  undistributed 
earnings have previously been subject to U.S. tax. As of December 31, 2015, we had undistributed earnings from non-U.S. operations 
of  approximately  $536  million  (including  approximately  $42  million  of  restricted  earnings,  which  are  not  available  for  dividends). 
Undistributed earnings of our China subsidiaries comprise $383 million of this total.  Additional U.S. federal and state income taxes of 
approximately $146 million would be required should the $536 million of such earnings be repatriated to the U.S. as dividends.  

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

RISKS RELATED TO OUR COMMON STOCK  
Variations in our quarterly operating results may cause our stock price to be volatile.  

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

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

(cid:120)  strength of the global economy and the stability of the financial markets;  
(cid:120)  general economic conditions in the countries where we sell our products;  

(cid:120)  seasonality and variability in the computing and communications market and our other end-markets;  

(cid:120)  the timing of our and our competitors’ new product introductions;  

(cid:120)  product obsolescence;  

(cid:120)  the scheduling, rescheduling and cancellation of large orders by our customers;  
(cid:120)  the cyclical nature of the demand for our customers’ products;  

(cid:120)  our ability to develop new process technologies and achieve volume production at our fabrication facilities;  

(cid:120)  changes in manufacturing yields;  

(cid:120)  adverse movements in exchange rates, interest rates or tax rates; and  

(cid:120)  the availability of adequate supply commitments from our outside suppliers or subcontractors.  

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

General  or  industry  specific  market  conditions  or  stock  market  performance  or  domestic  or  international  macroeconomic  and 
geopolitical factors unrelated to our performance also may affect the price of our stock. For these reasons, investors should not rely on 
recent or historical trends to predict future stock prices, financial condition, operating results or cash flows. In addition, as discussed in 
Part I, Item 3 “Legal Proceedings” of this Annual Report, we are involved in several lawsuits. Additional volatility in the price of our 
securities could result in the  filing of additional litigation,  which could result  in  substantial costs and the diversion of  management 
time and resources.  

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

As part of our growth strategy, we expect to review acquisition prospects that would implement our vertical integration strategy 
or offer other growth opportunities. From time to time, we may be in various stages of discussions and we may acquire businesses, 
products or technologies in the future. In the event of future acquisitions, we could:  

(cid:120)  use a significant portion of our available cash;  

(cid:120)  issue equity securities, which would dilute current stockholders’ percentage ownership;  

(cid:120)  incur substantial debt;  
(cid:120)  incur or assume contingent liabilities, known or unknown;  

- 24 - 

 
(cid:120)  incur amortization expenses related to intangibles;  

(cid:120)  incur large, immediate accounting write-offs; and 

(cid:120)  create goodwill and other intangible assets that may require impairment charges in the future. 

Such actions by us could harm our operating results 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 24% of our outstanding Common Stock, 
including  options  to  purchase  shares  of  our  Common  Stock  that  are  exercisable  within  60 days  of  December 31,  2015.  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 17% (approximately 8.1 million shares) of our Common Stock. Some of our 
directors and executive officers may have potential conflicts of interest because of their positions with LSC or their ownership of LSC 
common stock.  

Raymond Soong, the Chairman of the Board of Directors, is the Chairman of LSC, and is the Chairman of Lite-On Technology 
Corporation (“LTC”), a significant shareholder of LSC. C.H. Chen, our former President and Chief Executive Officer and currently 
the  Vice  Chairman  of  the  Board  of  Directors,  is  also  Vice  Chairman  of  LSC  and  a  board  member  of  LTC.  Dr. Keh-Shew  Lu,  a 
member of our Board of Directors and our President and Chief Executive Officer, is a board member of LTC and a board member of 
Nuvoton. L.P. Hsu, a member of the Board of Directors since 2007, serves as a consultant to LTC and a supervisor of the board of 
Nuvoton.  Several  of  our  directors  and  executive  officers  may  own  LSC  common  stock  or  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. In 2015, 2014 and 
2013, LSC accounted for approximately 2%, 3%, and 4%, respectively, of our silicon wafer supply, and 3%, 2% and 3%, respectively, 
of our finished goods supply.    

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

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

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

We were formed in 1959 under the laws of California and reincorporated in Delaware in 1968. We have had several transfer 
agents since being formed. 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.  

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

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

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

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

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

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

(i) 

(ii) 

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

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

(iii) 

the business combination is approved by a majority of the board of directors and by the affirmative vote of 66-2/3% of the 
outstanding voting stock that is not owned by the interested stockholder.  

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

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

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

Legal Proceedings.  

From time to time, we are involved in various legal proceedings that arise in the normal course of business. While we intend to 
defend any lawsuit vigorously, we presently believe that the ultimate outcome of any current pending legal proceeding will not have 
any  material  adverse  effect  on  our  financial  position,  cash  flows  or  operating  results.  However,  litigation  is  subject  to  inherent 
uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which could impact our 
business and operating results for the period in which the ruling occurs or future periods. See Note 15 of the Notes to Consolidated 
Financial Statements for detailed information regarding the status of our lawsuits.

On  February 23,  2016,  the  closing  sales  price  of  our  Common  Stock  as  reported  by  NasdaqGS  was  $17.98,  and  there  were 

approximately 326 holders of record of our Common Stock.  

Dividends  

We  have  never  declared  or  paid  cash  dividends  on  our  Common  Stock,  and  currently  do  not  intend  to  pay  dividends  in  the 
foreseeable  future  as  we  intend  to  retain  any  earnings  for  use  in  our  business.  Our  U.S.  banking  credit  facility  permits  us  to  pay 
dividends up to $1.5 million per fiscal year to our stockholders so long as we have not defaulted and are in continuing operation at the 
time  of  such  dividend.  The payment  of  dividends  is  within  the  discretion  of  our  Board  of  Directors,  and  will  depend  upon,  among 
other things, our earnings, financial condition, capital requirements, and general business conditions.  

Securities Authorized for Issuance Under Equity Compensation Plans  

The  information  regarding  our  equity  compensation  plans  required  to  be  disclosed  by  Item 201(d)  of  Regulation  S-K  is

Summary of the Year Ended December 31, 2015 

(cid:120)  We acquired Pericom Semiconductor Corporation in November for approximately $403.2 million;   

(cid:120)  During the fourth quarter we incurred costs of approximately $8 million for Pericom employees for restricted stock awards and 

change-in-control agreements.    

(cid:120)  Net sales were $849 million, a decrease of 4.7% from the $891 million in 2014;  

(cid:120)  Gross profit was $249 million, or 29.3% of net sales, a decrease of 10.1% from the $277 million, in 2014, or 31.1% of net sales. 

in 2014;  

(cid:120)  Selling  and  administrative  expenses  were  up  $5.5  million,  primarily  related  to  costs  associated  with  the  Pericom  acquisition, 

when compared to 2014; 

(cid:120)  Net income attributable to common stockholders was $24 million, or $0.49 per diluted share, compared to $64 million, or $1.31 

per diluted share, in 2014;  

(cid:120)  Cash flow from operations was $118 million compared to $134 million in 2014; and 

(cid:120)  We repurchased approximately $11 million or 466,010 shares of our outstanding common stock. 

Summary of the Year Ended December 31, 2014  

(cid:120)  Net sales for 2014 increased approximately 8% to $891 million, compared to $827 million in 2013;  

(cid:120)  Gross profit for 2014 was $277 million, or 31.1% of net sales, an increase of 17% from the $238 million, or 28.8% of net sales, 
in 2013.  BCD’s margins improved from 2013 to 2014 but still negatively impacted our total gross margin by approximately 160 
basis points, as compared to approximately 120 basis points in 2013;  

(cid:120)  Selling,  general  and  administrative  expenses,  as  a  percentage  of  net  sales,  decreased  100  basis  points  to  15.0%  for  2014

Business Acquisitions  

In  the  fourth  quarter  of  2015,  we  completed  the  acquisition  of  Pericom  for  aggregate  consideration  of  approximately  $403.2 
million, excluding acquisition costs, fees and expenses.  The cash portion of the acquisition price was funded by borrowings under our 
bank credit facilities and use of existing cash.  Pericom’s financial results have been included in our consolidated financial statements 
from November 24, 2015. 

In the first quarter of 2013, we completed the acquisition of BCD for an aggregate consideration of approximately $155 million, 

excluding acquisition costs, fees and expenses, plus a $5 million employee retention plan.  

Business Outlook  

Looking forward, we remain focused on achieving our goal of $1 billion in annual revenue with model gross margins of 35%. 
Acquisitions remain a key part of our growth strategy to reach our revenue goal. We have a solid pipeline of designs and expanded 
customer relationships across all regions and product lines. The success of our business depends on, among other factors, the strength 
of the global economy and the stability of the financial markets, our customers’ demand for our products, the ability of our customers 
to  meet  their  payment  obligations,  the  likelihood  of  customers  not  canceling  or  deferring  existing  orders,  and  the  strength  of 

- 33 - 

 
consumers’ demand for items containing our products in the end-markets we serve. We believe the long-term outlook for our business 
remains generally favorable despite the uncertainties in the global economy as we continue to execute on the strategy that has proven 
successful for us over the years. See “Risk Factors – The success of our business depends on the strength of the global economy and 
the stability of the financial markets, and any weaknesses in these areas may have a material adverse effect on our net sales, operating 
results and financial condition.” in Part I, Item 1A of this Annual Report for additional information.  

Factors Relevant to Our Results of Operations 

In 2015, the following factors affected, and, we believe, will continue to affect, our results of operations:  

(cid:120)  We  continue  to  experience  pressure  from  our  customers  to  reduce  the  selling  price  for  our  products,  and  we  expect  future 
improvements in  net income  to result primarily from increases in sales  volume and improvements in product  mix, as  well as 
manufacturing cost reductions in order to offset any reduction in average selling prices of our products.  

(cid:120)  For  the  years  ended  December 31,  2015,  2014  and  2013,  our  original  equipment  manufacturer  (“OEM”)  and  electronic 
manufacturing  services  (“EMS”)  customers  together  accounted  for  33%,  33%  and  37%  of  net  sales,  respectively,  while  our 
global network of distributors accounted for 67%, 67% and 63% of net sales, respectively.  

(cid:120)  Our gross profit margin was 29.3% in 2015, compared to 31.1% in 2014 and 28.8% in 2013. The decline in gross profit margin 
in 2015  was due to lower capacity utilization, product  mix and pricing. Future gross profit  margins  will depend primarily on 
market prices, our product mix, manufacturing cost savings, and the demand for our products.    

(cid:120)  For 2015, the percentage of our net sales derived from our Asian subsidiaries was 80%, compared to 80% in 2014 and 82% in 
2013. Europe accounted for approximately 11%, 10% and 9% of our net sales in 2015, 2014 and 2013, respectively. In addition, 
North America accounted for approximately 9%, 10% and 9% of our net sales in 2015, 2014 and 2013, respectively.  

(cid:120)  For 2015, our capital expenditures were approximately 16.2% of net sales, which is higher than our previous 5% to 9% of net 
sales model.  The increase in 2015 was primarily due to the Chengdu, China site expansion.  The Chengdu, China site expansion 
is a long-term, multi-year project that will provide us additional capacity as needed.  

(cid:120)  During 2015,  we invested approximately $133 million in  our  manufacturing and  wafer fabrication  facilities in  China, and  we 
expect  to  continue  to  invest  in  our  facilities,  although  the  amount  to  be  invested  will  depend  on  product  demand  and  new 
product developments.  

(cid:120)  Our investment in research and development for 2015 increased to approximately $57.0 million, or 6.7% of net sales, compared 
to $52 million, or 5.9% of net sales, in 2014. Approximately $1 million of the increase in research and development for 2015 is 
related to expense for restricted stock grants and change-in-control agreements for Pericom employees. We expect research and 
development costs to continue to increase as we look to invest in developing new products.  

Description of Sales and Expenses  

Net sales  

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

(cid:120)  The condition of the economy in general and of the semiconductor industry in particular.  

(cid:120)  Our customers’ adjustments in their order levels.  

(cid:120)  Changes in our pricing policies or the pricing policies of our competitors or suppliers.  

(cid:120)  The addition or termination of key supplier relationships.  
(cid:120)  The rate of introduction and acceptance by our customers of new products.  

(cid:120)  Our ability to compete effectively with our current and future competitors.  

(cid:120)  Our ability to enter into and renew key corporate and strategic relationships with our customers, vendors and strategic alliances,  

(cid:120)  Changes in foreign currency exchange rates.  

(cid:120)  A major disruption of our information technology infrastructure.  

(cid:120)  Unforeseen catastrophic events, such as armed conflict, terrorism, fires, typhoons and earthquakes, and  
(cid:120)  Any other disruptions, such as labor shortages, unplanned maintenance or other manufacturing problems.

Cost of goods sold  

Cost of goods sold includes manufacturing costs for our semiconductors and our wafers. These costs include raw materials used 
in  our  manufacturing  processes  as  well  as  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, investor relations, accounting, consulting and other operating expenses.  Also included in 
selling, general and administrative expenses are acquisition costs from business combinations.  

Research and development expenses  

Research  and  development  expenses  consist  of  compensation  and  associated  costs  of  employees  engaged  in  research  and 
development projects, as well as materials and equipment used for these projects. Research and development expenses are primarily 
associated with our wafer facilities in China, Kansas City, Missouri and Manchester, U.K. and our manufacturing facilities in Taiwan 
and China, as well as with our engineers in the U.S. and Taiwan. All research and development expenses are expensed as incurred.  

Amortization of acquisition-related intangible assets  

Amortization  of  acquisition-related  intangible  assets  consists  of  assets  such  as  developed  technologies  and  customer 

relationships.  

Impairment of goodwill  

Impairment of goodwill consists of the impairment amount recognized as a result of a reporting unit’s goodwill exceeding its 

implied fair value.  

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

Gain on sale of assets  
Gain on sale of assets consists of the sale of certain assets such as intangibles or buildings.  

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 and other debt instruments.  

Gain (loss) on securities carried at fair value  

From time to time we may hold investments in the form of common stock or some other similar equivalent and have elected fair 

value accounting treatment.  

Income tax provision  

Our  global  presence  requires  us  to  pay  income  taxes  in  a  number  of  jurisdictions.  See  Note  10  of  “Notes  to  Consolidated 

Financial Statements” for additional information.  

Net income attributable to noncontrolling interest  
This represents the minority investors’ share of our subsidiaries’ earnings.

  % Change 

The decrease in net sales for 2015 compared to 2014 was representative of weaker demand across several key end markets and 
geographies and lower average selling prices.  The decrease in net sales was partially offset by revenue of approximately $15 million 
recorded related to Pericom. The softer environment negatively impacted the loading and utilization at our manufacturing facilities.  
As a percent of sales, cost of goods sold increased to 70.7% for 2015, compared to 68.9% in the same period last year, reflecting the 
decline in total revenue, the lower average selling prices, and the reduction in factory utilization.  Cost of sales included $10.7 million 
from  Pericom  operations.    Additionally  there  was  approximately  $1  million  of  expense  for  restricted  stock  awards  and  change-in-
control agreements for Pericom employees.

Total operating expenses for 2015 increased approximately $14 million, or 7% when compared to 2014.  Included in operating 
expenses  for  2015  are  approximately  $5  million  from  Pericom  operations  and  additional  expenses  of  approximately  $7  million  for 
Pericom  employees  for  restricted  stock  awards  and  change-in-control  agreements.   Of  the  components  within  operating  expenses, 
R&D, as a percentage of sales, increased slightly to 6.7% for 2015, compared to 5.9% in the same period last year.  R&D expense 
increased primarily due $1  million of expense for restricted stock grants and change-in-control agreements  for Pericom employees, 
packaging  related  development  activity  and  increased  investment  associated  with  the  Pericom  acquisition  in  November  2015, 
amortization of acquisition-related intangible assets increased reflecting the Pericom acquisition, and the loss on sale of assets reflects 
the impairment of old assets during 2015 in our BCD wafer fab that are not able to convert from six inch to eight inch wafer diameter 
production,  and  the  gain  realized  on  the  sale  of  fixed  assets  in  2014  that  did  not  repeat in  2015.   SG&A,  as  a  percentage  of  sales, 
increased slightly to 16.4% of sales for 2015, compared to 15.0% in the same period last year. Included in SG&A expense for 2015 
was approximately $6 million for Pericom employees related to restricted stock grants and change-in-control agreements.

Interest income and gains on securities carried at fair value decreased as we held lower investable balances during the year.  Our 
investment  balance  increased  at  year  end  due  to  the  investments  acquired  in  the  Pericom  acquisition.      Other  income  (expense) 
decreased due to a higher level of currency gains on Taiwan currency recorded in 2014 when compared to 2015.

We recognized income tax expense of approximately $14 million for 2015, resulting in an effective tax rate of approximately 
35%,  as  compared  to  24%  for  2014.  The  decrease  in  tax  expense  from  2014  to  2015  was  due  primarily  to  the  decrease  in  pretax 
earnings during the same period.  The increase in the effective tax rate from 2014 to 2015 was due primarily to an increase in earnings 
in higher tax jurisdictions, relative to earnings in lower tax jurisdictions, and to the decrease in overall pretax earnings during the same 
period.

Net sales for 2014 increased due to an approximately 8% increase in units sold, which was due primarily to net sales increases 

in our Asia markets.  Average selling prices for 2014 were flat compared to 2013. 

Cost of goods sold as a percentage of sales, decreased from 71.2% for 2013 to 68.9% for 2014. Our average unit cost decreased 

by approximately 3%.  

Gross profit as a percentage of net sales was 31.1% for 2014, compared to 28.8% for 2013. The increase in gross margin was 

primarily due to lower gold prices, improved product mix, copper wire conversion and cost reduction efforts.

SG&A  for 2014 increased due primarily to increased selling expenses, partly offset by reduced retention bonus related to the 

BCD acquisition. SG&A, as a percentage of net sales, improved to 15.0% in 2014, from 16.0% in 2013. 

R&D for 2014 increased due primarily to an increase in employee related costs.  R&D, as a percentage of net sales, was 6% for 

both 2014 and 2013.   

Amortization  of  acquisition-related  intangibles  was  due  primarily  to  the  amortization  expense  on  the  acquired  intangibles  of 

BCD.  

Goodwill impairment for 2013 was related to Eris.  There was no goodwill impairment for 2014.  

There were no restructuring related costs for 2014.  The restructuring in 2013 related to termination and severance costs of our 

U.K. development team and the closure of our New York sales office. 

We recorded a gain on sale of assets for 2014, due to the sale of a building in Taiwan.

Interest  income  for  both  2014  and  2013  was  relatively  flat  consisting  of  interest  earned  on  bank  deposits  and  short-term 

investments.  

Interest expense for 2014 declined in 2014 compared to 2013 primarily due to the repayment of $40 million on our revolving 

senior credit facility. 

Gain on securities resulted primarily from unrealized and realized gains on trading securities.   

Other income for 2014 included approximately $2 million in currency gains.  Included in other income for 2013 were foreign 

currency gains and miscellaneous income.

We recognized income tax expense of approximately $20 million for 2014, resulting in an effective tax rate of approximately 
24%, as compared to 38% for 2013. Income tax expense for 2013 includes approximately $5 million of additional tax expense related 
to a tax audit by the China tax authorities. The increase in tax expense from 2013 to 2014 was due primarily to the increase in pretax 
earnings during the same period.   

Net  (income)  loss  attributable  to  noncontrolling  interest  primarily  represents  the  minority  investors’  share  of  the  earnings  of 
certain China subsidiaries and Eris. The noncontrolling interest in the subsidiaries and their equity balances are reported separately in 
the  consolidation  of  our  financial  statements.  The  loss  attributable  to  noncontrolling  interest  for  2013  was  due  primarily  to  the 
goodwill impairment attributable to Eris, of which 49% was recognized in noncontrolling interest. 

Financial Condition  
Liquidity and Capital Resources  

Our primary sources of liquidity are cash and cash equivalents, funds from operations and, if necessary, borrowings under our 
credit facilities. On September 2, 2015, the Company and Diodes International B.V. (the “Foreign Borrower” and, collectively with 
the Company, the “Borrowers”), and certain subsidiaries of the Company as guarantors, entered into an Amendment No. 3 to Credit 
Agreement,  Incremental  Term  Assumption  Agreement,  Limited  Waiver  and  Consent  (the  “Amendment”)  with  Bank  of  America, 
N.A.,  as  Administrative  Agent,  and  the  lenders  party  to  the  Amendment  (collectively,  the  “Lenders”),  which  amends  the  Credit 
Agreement dated January 8, 2013 (as previously amended by Amendment No. 1 to Credit Agreement and Limited Waiver dated as of 
November 1, 2013 and Amendment No. 2 to Credit Agreement and Amendment No. 1 to Collateral Agreement dated as of June 19, 
2015) (as previously amended and as amended by the Amendment, the “Credit Agreement”).  

The Amendment provided the Company with a $400 million revolving senior credit facility (the “Revolver”), which includes a 
$10 million swing line  sublimit, a $10 million letter of credit sublimit, and a $20 million alternative currency sublimit, and a $100 
million  term  loan  facility  (the  “Term  Loan  Facility”).  We  may  from  time  to  time  request  additional  increases  in  the  aggregate 
commitments under the Credit Agreement of up to $200 million, subject to the Lenders electing to increase their commitments or by 
means of the addition of new Lenders, and subject to at least half of each increase in aggregate commitments being in the form of term 
loans, with the remaining amount of each increase being an increase in the amount of the Revolver. The Revolver and the term loan 
both  mature  on  January  8,  2018,  and  as  of  December  31,  2015,  $464.5  million  was  outstanding.  In  addition,  we  have  short-term 
foreign credit facilities with borrowing capacity of approximately $84 million with $1 million used for import and export guarantees. 
We also have foreign long-term debt of approximately $2 million.  Our primary liquidity requirements have been to meet our capital 
expenditure  needs  and  to  fund  on-going  operations.  For  2015  and  2014,  and  2013,  our  working  capital  was  $571  million,  $526 
million, and $493 million, respectively.  In 2015 our working capital increased due to increases in short-term investments, accounts 
receivable  and  inventories.    These  increases  were  driven  by  the  Pericom  acquisition.    Our  working  capital  increased  in  2014  due 
primarily to the increase in cash and cash equivalents, and a decrease in accounts payable. We expect cash generated by our operations 
together  with  existing  cash,  cash  equivalents,  short-term  investments  and  available  credit  facilities  to  be  sufficient  to  satisfy  our 
working capital needs, capital asset purchases, outstanding commitments and other liquidity requirements associated with our existing 
operations for at least the next 12 months.

In 2015, 2014 and 2013, our capital expenditures were approximately $138 million, $59 million and $44 million, respectively, 
which  includes  approximately  $62  million,  $18  million  and  $7  million  of  capital  expenditures  related  to  the  investment  agreement 
with  the  Management  Committee  of  the  Chengdu  Hi-Tech  Industrial  Development  Zone  (the  “CDHT”)  for  2015,  2014  and  2013, 
respectively. Our capital expenditures for these periods were primarily related to manufacturing expansion in our facilities in China 
and, to a lesser extent, our wafer fabrication facility in the U.S. and office buildings. Capital expenditures in 2015 were approximately 
16% of our net sales, which was greater than our previous historical 5% to 9% model due to the construction and furnishing of the 
Chengdu manufacturing site.  

In  2010,  we  announced  an  investment  agreement  with  the  Management  Committee  of  the  CDHT.  Under  this  agreement,  we 
formed  a  joint  venture  with  a  Chinese  partner,  Chengdu  Ya  Guang  Electronic  Company  Limited  (“Ya  Guang”),  to  establish  a 
semiconductor assembly and test facility in Chengdu, China. We currently own 95% of the joint venture. The CDHT granted the joint 
venture a 50 year land lease, provides corporate and employee tax incentives, tax refunds, subsidies and other financial support. This 
is a long-term, multi-year project that will provide us additional capacity as needed. As of December 31, 2015, we have invested $120 
million, primarily for infrastructure, buildings and equipment related capital expenditures.  

In  November 2015,  we  completed  the  acquisition  of  Pericom  for  an  aggregate  consideration  of  approximately  $403  million, 
excluding acquisition costs, fees and expenses. The acquisition was funded by drawings on our bank credit facility and use of existing 
funds. The acquisition is a continuation of our strategy to expand our semiconductor product offerings and to maximize our market 
opportunities.    In  the  future  we  may  acquire  product  lines  or  companies  in  order  to  enhance  our  portfolio  and  accelerate  our  new 
offerings,  which  could  have  a  material  impact  on  liquidity  and  require  us  to  draw  down  on  our  credit  facilities  or  increase  our 
borrowings and limits.  

In March 2013, we completed the acquisition of BCD for an aggregate consideration of approximately $155 million, excluding 
acquisition costs, fees and expenses, plus a $5 million employee retention plan. The acquisition was funded by borrowings under our 
bank credit facilities.  

We  intend  to  permanently  reinvest  overseas  all  of  our  earnings  from  our  foreign  subsidiaries,  except  to  the  extent  such 
undistributed earnings have previously been subject to U.S. tax.  Accordingly, deferred U.S. taxes are not recorded on undistributed 
foreign earnings.  As of December 31, 2015, our foreign subsidiaries held approximately $257 million of cash, cash equivalents and 
investments of which approximately $166 million would be subject to a potential tax if repatriated to the U.S as dividends. 

Restricted  cash  is  pledged  as  collateral  when  we  enter  into  agreements  with  banks  for  certain  banking  facilities. As  of 
December 31, 2015, restricted cash of $1 million was pledged as collateral for issuance of bank acceptance notes and letters of credit.  

As  of  December 31,  2015,  we  had  short-term  investments  of  approximately  $65  million. These  investments  are  highly  liquid 
with  maturity dates  greater than three  months at the date of purchase.  The increase from $12 million in 2014, to 2015 reflects the 
short-term investment portfolio acquired as part of Pericom.  We generally can access these investments in a relatively short amount 
of time but in doing so we generally forfeit a portion of interest income.  

Discussion of Cash Flows  

Cash  and  cash  equivalents  decreased  approximately  $25  million  to  $218  million  in  2015  from  $243  million  in  2014.    The 
decrease  is  primarily  driven  by  lower  revenue,  funds  used  to  purchase  Pericom,  to  pay  down  long-term  debt  and  fund  operating 
expenses. Cash and cash equivalents increased from $197 million at December 31, 2013, to $243 million at December 31, 2014. The 
increase during 2014 was primarily due to the increase in cash provided by operating activities and cash used in connection with the 
acquisition of BCD in 2013, and was offset by the advance on the revolving note.

Operating Activities  

Net cash provided by operating activities for 2015 was approximately $118 million, due primarily to $27 million of net income, 
$80  million  in  depreciation  and  amortization,  $19  million  from  non-cash  share-based  compensation,  partially  offset  by  a  total  of 
approximately  $10  million  net  decrease  in  other  operating  asset  and  operating  liability  accounts.    Net  cash  provided  by  operating 
activities  for  2014  was  approximately  $134 million,  due  primarily  to  $66 million  of  net  income,  $77  million  of  depreciation  and 
amortization and $14 million from non-cash share-based compensation, partially offset by decreases in prepaids and accounts payable. 
Net  cash  provided  by  operating  activities  was  $110 million  for  2013,  due  primarily  to  $24  million  of  net  income,  $74  million  of 
depreciation  and  amortization,  $14  million  from  non-cash,  share-based  compensation,  and  a  $15  million  reduction  in  inventories, 
partially offset by increases in accounts receivable and decreases in accounts payable.   

Net  cash  provided  by  operating  activities  decreased  approximately  $16 million  from  2014  to  2015.  This  decrease  resulted 
primarily from a decrease in net income, partially offset by non-cash related items such as depreciation, amortization, and changes in 
operating assets and liabilities.  

Net  cash  provided  by  operating  activities  increased  approximately  $24 million  from  2013  to  2014.  This  increase  resulted 
primarily from an increase in net income, non-cash related items such as depreciation, amortization, and changes in operating assets 
and liabilities.  

Investing Activities  

Net  cash  used  by  investing  activities  for  2015  was  approximately  $460 million.    Included  in  our  investing  activities  is  $349 
million of acquisitions, net of cash acquired.  We had capital expenditures of $133 million.  We had sales of short-term investments, 
net of purchases of approximately $18 million.  

Net  cash  used  by  investing  activities  for  2014  was  approximately  $43 million,  due  primarily  to  $58  million  in  capital 
expenditures, and $2 million in equity investment, partially offset by a $14 million decrease in short-term investments and restricted 
cash.  

Net  cash  used  by  investing  activities  for  2013  was  approximately  $186 million,  due  primarily  to  $125  million  used  for 
acquisitions, net of cash acquired, $47 million in capital expenditures and $23 million used for purchases of short-term investments, 
partially offset by other investing items.  

Financing Activities  

Net  cash  provided  by  financing  activities  for  2015  was  approximately  $321 million,  due  primarily  to  the  additional  debt  of 
approximately $391 million we incurred to purchase Pericom.  This increase was partially offset by the repayment of approximately 
$66 million of long-term debt during 2015.  

Net cash used by financing activities for 2014 was approximately $36 million, due primarily to a $47 million reduction of debt, 

partially offset by $6 million in proceeds from the stock options exercised.  

Net cash provided by financing activities for 2013 was approximately $112 million, due primarily to a $181 million draw down 

on our Revolver, partially offset by $62 million of debt repayments. 

Debt instruments  

The  Credit  Agreement  as  contains  certain  financial  and  non-financial  covenants,  including,  but  not  limited  to,  a  maximum 
Consolidated  Leverage  Ratio,  a  minimum  Consolidated  Fixed  Charge  Coverage  Ratio,  and  restrictions  on  liens,  indebtedness, 
investments,  fundamental  changes,  dispositions,  and  restricted  payments  (including  dividends)  (as  such  terms  are  defined  in  the 
Amendment or the Credit Agreement). 

As  of  December 31,  2015,  our  U.S.  and  Asia  subsidiaries  had  unused  and  available  credit  lines  of  up  to  an  aggregate  of 
approximately $83 million, with several financial institutions. In some cases, our foreign credit lines are unsecured, uncommitted and 
may be repayable on demand, except for two Taiwanese credit facilities that are collateralized by assets. Our foreign credit lines bear 
interest at LIBOR or similar indices plus a specified margin. At December 31, 2015, no amounts were outstanding under these lines of 
credit.  See  “Liquidity  and  Capital  Resources”  above  and  Note  7  of  “Notes  to  Consolidated  Financial  Statements”  of  this  Annual 
Report for additional information.

Off-Balance Sheet Arrangements  

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

Interest on long-term debt assumes there is no change in long-term debt from the balance outstanding as of December 31, 2015, 
other than required principal payments.  The Revolver and Term Loan mature in January 2018. 

Tax liabilities are not included in the above contractual obligations as we cannot make reasonable estimates of the amount and 
period in which those tax liabilities would be paid. See “Accounting for income taxes” below and Note 10 of “Notes to Consolidated 
Financial Statements” of this Annual Report for additional information.  

Critical Accounting Policies and Estimates  

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

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

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

Revenue recognition  

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

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

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

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

Inventories  

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

Accounting for income taxes  

As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each 
of the tax jurisdictions in which we operate. This process involves using an asset and liability approach whereby deferred tax assets 
and  liabilities  are  recorded  for  differences  in  the  financial  reporting  bases  and  tax  bases  of  our  assets  and  liabilities.  A  valuation 
allowance is provided against deferred tax assets unless it is more likely than not that such deferred tax assets will be realized. This 
analysis requires considerable judgment and is subject to change to reflect future events and changes in the tax laws.  

The benefit of a tax position is recognized only if it is more likely than not that the tax position would be sustained based on its 
technical merits in a tax examination, using the presumption the tax authority has full knowledge of all relevant facts regarding the 
position. The amount of benefit recognized is the largest amount of tax benefit that is  greater than 50% likely of being realized on 
ultimate settlement with the tax authority. For tax positions not meeting the more likely than not test, no tax benefit is recorded.  

Goodwill and other indefinite lived intangible assets  

Goodwill is tested for impairment on an annual basis, on October 1, and between annual tests if indicators of potential impairment 
exist. We use the simplified goodwill impairment test, which allows us to first assess qualitatively whether it is necessary to perform step 
one of the two-step annual goodwill impairment test. We are required to perform step one and calculate the fair value of our reporting 
units only if we conclude that it is more likely than not that a reporting unit’s fair value is less than its carrying value (that is, a likelihood 
of more than 50%). The qualitative analysis, which is referred to as step zero, is performed, and we consider all relevant factors specific to 
our reporting units. Some factors considered in step zero are macroeconomic conditions, industry and market considerations, cost factors, 
overall financial performance, events affecting a reporting unit and other relevant entity-specific events. If any reporting unit fails step 
zero, its goodwill and other indefinite lived intangible assets will be tested using the two-step process. The first step requires a comparison 
of the fair value of the reporting unit to the respective carrying value. If the reporting unit fails step one, meaning that its carrying value 
exceeds its fair value, then the second step must be performed. The second step computes the amount of impairment, if any, by comparing 
the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting 
unit’s goodwill exceeds its implied fair value, an impairment loss will be recognized.  

Share-based compensation  

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

Fair value measurements  

Fair value is an exit price, representing the amount that  would be received to sell an asset or paid to transfer a liability in an 
orderly  transaction  between  market  participants  at  the  measurement  date.  As  such,  fair  value  is  a  market-based  measurement  that 
should be determined based on the assumptions that market participants would use in pricing an assets or liability. Fair value is based 

- 43 - 

 
on  a  hierarchy  of  valuation  techniques,  which  is  determined  on  whether  the  inputs  to  those  valuation  techniques  are  observable or 
unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market 
assumptions.  These  two  types  of  inputs  create  a  three-tier  fair  value  hierarchy,  which  prioritizes  the  inputs  used  in  measuring  fair 
value as follows:  

Level 1:   Quoted prices for identical instruments in active markets. 

Level 2: 

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

Level 3: 

Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are 
unobservable. 

Our defined benefit plan assets are valued under methods of fair value.  

Defined benefit plan  

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

Contingencies  

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

Quantitative and Qualitative Disclosures About Market Risk.  

Item 7A. 
Foreign Currency Risk  

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

Effect on Reporting Income  

Certain  of  our  subsidiaries  have  a  functional  currency  that  differs  from  the  currencies  in  which  some  of  their  expenses  are 
denominated. Our income and expenses are based on a mix of currencies and a decline in one currency relative to the other currencies 
could  adversely  affect  our  results  of  operations.  Furthermore,  our  results  of  operations  are  reported  in  U.S.  dollars,  which  is  our 
reporting currency. In the event the U.S. dollar weakens against a foreign currency,  we  will experience a currency transaction loss, 
which could adversely affect our results of operations. If a foreign currency were to weaken (or strengthen) by 1.0% against the U.S. 
dollar, we would experience currency transaction gain (or loss) of less than $1 million per quarter.  

- 44 - 

 
  
 
 
  
 
 
  
 
 
Foreign Currency Transaction Risk  

We also are subject to foreign currency risk arising from intercompany transactions that are expected to be settled in cash in the 
near  term  where  the  cash  balances  are  held  in  denominations  other  than  our  subsidiaries’  functional  currency.  If  exchange  rates 
weaken against the functional currency, we would incur a remeasurement gain in the value of the cash balances, and if the exchange 
rates strengthen against the functional currency, we would incur a remeasurement loss in the value of the cash balances, assuming the 
net monetary asset balances remained constant. Our ultimate realized gain or loss with respect to currency fluctuations will generally 
depend on the size and type of transaction, the size and currencies of the net monetary assets and the changes in the exchange rates 
associated with these currencies. If the Chinese Yuan, the Taiwanese dollar, the Euro and the British Pound Sterling were to weaken 
(or strengthen) by 1.0% against the U.S. dollar, we would experience currency transaction gain (or loss) of less than $1 million per 
quarter. Net foreign exchange transaction gains (or losses) are included in other income and expense.  

Foreign Currency Translation Risk  

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

Foreign Currency Denominated Defined Benefit Plans  

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

As  of  December 31,  2015,  the  plan  was  underfunded  and  a  liability  of  approximately  $29  million  was  reflected  in  our 
consolidated financial statements as a noncurrent liability. The amount recognized in accumulated other comprehensive income was a 
net  loss  of  $31  million.  If  the  British  Pound Sterling  were  to  (weaken)  or  strengthen  by  1.0%  against  the  U.S.  dollar,  we  would 
experience currency translation liability (decrease) or increase of less than $1 million. The weighted-average discount rate assumption 
used  to  determine  benefit  obligations  as  of  December 31,  2015  was  4.0%.  A  0.2%  increase/(decrease)  in  the  discount  rate  used  to 
calculate  the  net  period  benefit  cost  for  the  year  would  reduce/increase  annual  benefit  cost  by  less  than  $1  million.  A  0.2% 
increase/(decrease) in the discount rate used to calculate the year-end projected benefit obligation would increase/(decrease) the year–
end projected benefit obligation by approximately $5.6 million. The expected return on plan assets is determined based on historical 
and  expected  future  returns  of  the  various  assets  classes  and  as  such,  each  1.0%  increase/(decrease)  in  the  expected  rate  of  return 
assumption would increase/(decrease) the net period benefit cost by approximately $1 million. The asset value of the defined benefit 
plan  has  been  volatile  in  recent  years  due  primarily  to  wide  fluctuations  in  the  U.K.  equity  markets  and  bond  markets.  See  “Risk 
Factors - Changes in actuarial assumptions for our defined benefit plan could increase the volatility of the plan’s asset value, require 
us to increase cash contributions to the plan and have a negative impact on our cash flows, operating results and financial condition” 
in Part I, Item 1A of this Annual Report for additional information.  

Interest Rate Risk  

We have credit facilities with financial institutions in the U.S., Asia and Europe as well as other debt instruments with interest 
rates equal to LIBOR or similar indices plus a negotiated margin. A rise in interest rates could have an adverse impact upon our cost 
of  working  capital  and  our  interest  expense.  As  a  matter  of  policy,  we  do  not  enter  into  derivative  transactions  for  speculative 
purposes.  As  of  December 31,  2015,  our  outstanding  principal  debt  included  $465  million  outstanding  under  our  revolving  senior 
credit  facility  and  term  loan,  $2  million  outstanding  under  foreign  long  term  liabilities  and  $1  million  used  for  import  and  export 
guarantees and bank acceptance notes. Based on an increase or decrease in interest rates by 1.0% for the year on our credit facilities, 
our annual interest rate expense would increase or decrease by approximately $5 million.  

- 45 - 

 
Political Risk  

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

Inflation Risk  

Inflation did not have a material effect on net sales or net income in fiscal year 2015. A significant increase in inflation could 

affect future performance.  

Credit Risk  

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

Disclosure Controls and Procedures  

Our  Chief  Executive  Officer,  Keh-Shew  Lu,  and  Chief  Financial  Officer,  Richard  D.  White,  with  the  participation  of  our 
management,  carried  out  an  evaluation  of  the  effectiveness  of  our  disclosure  controls  and  procedures  as  of  December 31,  2015, 
pursuant to and as required by Rule 13a-15(b) under the Securities Exchange Act of 1934 (“Exchange Act”). Based on that evaluation, 
our Chief Executive Officer and Chief  Financial Officer concluded that, as of December 31, 2015, due to the  material  weakness in 
internal  control  over  financial  reporting  described  below,  our  disclosure  controls  and  procedures  were  not  effective  to  ensure  that 
information required to be included in this report is:  

o 

o 

recorded, processed, summarized and reported within the time period specified in the Commission’s rules and forms; 
and  

accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial 
Officer, to allow timely decisions regarding required disclosure. 

Notwithstanding  the  identified  material  weakness,  management,  including  our  Chief  Executive  Officer  and  Chief  Financial 
Officer, believes the consolidated financial statements included in this  Annual Report on Form 10-K fairly represent  in all  material 
respects  our  financial  condition,  results  of  operations  and  cash  flows  at  and  for  the  periods  presented  in  accordance with  generally 
accepted accounting principles in the United States of America (“U.S. GAAP”). 

Management's Annual Report on Internal Control Over Financial Reporting 

Our  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,  our  Chief  Executive  Officer  and  the  Chief 
Financial  Officer  and  implemented  by  our  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 U.S. 
GAAP.  

- 46 - 

 
 
Our  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 our assets; (2) provide reasonable 
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and 
that receipts and expenditures of ours are being made only in accordance with authorizations of our management and directors; and 
(3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets 
that could have a material effect on the financial statements.   

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial 
Officer,  we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the  framework in 
Internal Control - Integrated Framework (2013) 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 a material weakness exists in our internal control 
over financial reporting as described below. A material weakness is a deficiency or a combination of deficiencies, in internal control 
over  financial  reporting,  such  that  there  is  a  reasonable  possibility  that  a  material  misstatement  of  our  annual  or  interim  financial 
statement will not be prevented or detected in a timely basis. 

As permitted by the rules of the SEC, we have excluded Pericom Semiconductor Corporation and its subsidiaries (collectively, 
“Pericom”) from our annual assessment of the effectiveness of internal control over financial reporting for the year ending December 
31, 2015, the year of acquisition.  

The total assets (including goodwill and intangible assets), net assets (including goodwill and intangible assets), net sales and 
net income of Pericom represented approximately 28% of our total assets, 45% of our net assets, less than 2% of our net sales and (4%) 
of our net income, respectively, on a consolidated basis, as of and for the year ended December 31, 2015. 

In the foregoing evaluation of the effectiveness of our internal control over financial reporting, management identified certain 
errors  in  its  accounting  for  equity  awards  and  change-in-control  agreements  related  to  the  Pericom  acquisition  and,  as  a  result, 
concluded  that  the  Company  did  not  have  adequate  resources  regarding  accounting  for  equity  awards  exchanged  for  and  the 
accounting for change-in-control agreements related to the Pericom acquisition. If not corrected this control deficiency could result in 
a material misstatement that would not be prevented or detected. Because of the material weakness, management concluded that the 
Company did not  maintain effective internal control over financial reporting as of December 31, 2015 based on criteria in Internal 
Control - Integrated Framework (2013) issued by COSO.  

The effectiveness of our internal control over financial reporting as of December 31, 2015 has been audited by Moss Adams 
LLP,  an  independent  registered  public  accounting  firm,  as  stated  in  their  report  which  appears  in  Item 8  of  this  Annual  Report  on 
Form 10-K. 

Changes in Internal Control Over Financial Reporting 

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

Material Weakness Remediation Efforts 

Management has enhanced, and will continue to enhance, our controls, including refinements and enhancements to the design 
(including the review and supervision and the level of precision) of certain controls over the accounting for equity awards and change-
in-control  agreements  in  a  business  combination.  The  Company  has  identified  process  improvements  to  remediate  the  material 
weakness  discussed  above  and  has  commenced  the  implementation  of  these  enhanced  controls.  Management  anticipates  these 
enhanced controls  will be effective at the time of any  future business combination.  At  December 31, 2015, there continues to be a 
reasonable possibility that a material misstatement related to the accounting for equity awards and change-in-control agreements in a 
business combination may not be prevented or detected.  

Management  plans  to  implement  the  following  steps  to  remediate  the  material  weakness  discussed  above  and  improve  its 
internal  control  over  financial  reporting  related  to  equity  awards  and  change-in-control  agreements  in  a  business  combination: 
improving the documentation of policies and procedures (and related controls) surrounding such equity awards and change-in-control 
agreements; developing a work flow document including internal controls for completing future acquisitions; assessing the capacity of 
its  accounting  resources  available  for  the  future  acquisitions  to  evaluate  and  account  for  the  equity  awards  exchanged  and  the 
accounting  for  change-in-control  agreements  in  accordance  with  U.S.  GAAP;  providing  complete  and  substantive  documentation 
around  the  review  processes  for  such  equity  awards  and  change-in-control  agreements;  determining  the  sufficiency  of  internal 

- 47 - 

 
resources and the availability of external resources to prepare and analyze non-routine transactions; and if external resources are used, 
involving  these  resources  early  in  the  process  and  ensuring  appropriate  internal  resources  are  available  to  review  materials  at  a 
sufficient level to detect errors. 

Management  is  committed  to  improving  the  Company’s  internal  control  processes  and  will  develop  and  present  to  the  Audit 
Committee a plan and timetable for the implementation of the remediation measures described above and will meet frequently  with 
the Audit Committee to monitor the status of remediation activities. Management believes that the measures described above should 
remediate  the  material  weakness  identified  and  strengthen  the  Company’s  internal  control  over  financial  reporting  related  to 
accounting for equity awards and change-in-control agreements in a business combination. As the Company continues to evaluate and 
improve  its  internal  control  over  financial  reporting,  additional  measures  to  remediate  the  material  weakness  or  modifications  to 
certain of the remediation procedures described above may be necessary and will be undertaken as necessary.  

As permitted by the rules of the SEC, we have excluded Pericom from our annual assessment of the effectiveness of internal 
control over financial reporting  for the  year ending December 31, 2015, the year of acquisition. Management continues to evaluate 
Pericom’s internal controls over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

The Board of Directors and Stockholders 
Diodes Incorporated and Subsidiaries 

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Diodes  Incorporated  and  Subsidiaries  (the  “Company”)  as  of 
December 31, 2015 and 2014, and the related consolidated statements of income, comprehensive income, equity, and cash flows for 
each of the three years in the period ended December 31, 2015. We also have audited the Company’s internal control over financial 
reporting  as  of  December  31,  2015, based  on  criteria  established  in  Internal  Control  -  Integrated  Framework  (2013)  issued  by  the 
Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.  As  described  in  Management’s  Annual  Report  on  Internal 
Control Over Financial Reporting, in November 2015, the Company acquired Pericom Semiconductor Corporation (“Pericom”). For 
the  purposes  of  assessing  internal  control  over  financial  reporting,  management  excluded  Pericom,  whose  financial  statements 
constitute 15% of the Company’s consolidated total assets (excluding approximately $210 million of goodwill and intangible assets, 
which were integrated into the Company’s control environment) and approximately 2% of the Company’s consolidated net sales as of 
and  for  the  year  ended  December  31,  2015.  Accordingly,  our  audit  did  not  include  the  internal  control  over  financial  reporting  of 
Pericom.  The  Company’s  management  is  responsible  for  these  consolidated  financial  statements,  for  maintaining  effective  internal 
control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the 
accompanying  Management’s  Annual  Report  on  Internal  Control  over  Financial  Reporting  appearing  under  Item  9A.  Our 
responsibility is to express an opinion on these consolidated financial statements and an opinion on the Company’s internal control 
over financial reporting based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those 
standards  require  that  we  plan  and  perform  the  audits  to  obtain  reasonable  assurance  about  whether  the  consolidated  financial 
statements  are  free  of  material  misstatement  and  whether  effective  internal  control  over  financial  reporting  was  maintained  in  all 
material  respects.  Our  audits  of  the  consolidated  financial  statements  included  examining,  on  a  test  basis,  evidence  supporting  the 
amounts and disclosures in the consolidated financial statements, assessing the accounting principles  used and significant estimates 
made  by  management,  and  evaluating  the  overall  consolidated  financial  statement  presentation.  Our  audit  of  internal  control  over 
financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our 
audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits 
provide a reasonable basis for our opinions. 

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

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

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a 
reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or 
detected on a timely basis. The following material weakness has been identified and included in management’s assessment:  

The Company did not have effective controls to provide reasonable assurance as to the application of generally accepted accounting 
principles relating to the accounting for equity awards and change-in-control agreements in a business combination due to the lack of 
adequate resources in its accounting department.  

We  considered  the  material  weakness  in  determining  the  nature,  timing,  and  extent  of  audit  tests  applied  in  our  audit  of  the 
consolidated  financial  statements  as  of  and  for  the  year  ended  December  31,  2015,  of  the  Company,  and  our  opinion  on  such 
consolidated financial statements was not affected. 

- 51 - 

 
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial 
position of Diodes Incorporated and Subsidiaries as of December 31, 2015 and 2014, and the consolidated results of their operations 
and  their  cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2015,  in  conformity  with  generally  accepted 
accounting principles in the United States of America. Also in our opinion, because of the effect of the material weakness identified 
above  on  the  achievement  of  the  objectives  of  the  control  criteria,  the  Company  has  not  maintained  effective  internal  control  over 
financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued 
by the Committee of Sponsoring Organizations of the Treadway Commission. 

As discussed in Note 1 to the consolidated financial statements, the Company retrospectively changed the manner in which it accounts 
for  the  balance  sheet  classification  of  deferred  taxes  due  to  the  adoption  of  Accounting  Standards  Update  2015-17,  Balance  Sheet 
Classification of Deferred Taxes.

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

Note 1 – SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES 

Nature  of  operations  – Diodes Incorporated and its subsidiaries (collectively, the “Company” or “we” or “our”) is a leading 
global designer, manufacturer and supplier of high-quality, application-specific standard products within the broad discrete, logic and 
analog semiconductor markets, serving the consumer electronics, computing, communications, industrial and automotive markets. Our 
primary focus is on low pin count semiconductor devices with one or more active and/or passive components. Our products include 
diodes,  rectifiers,  transistors,  MOSFETs,  protection  devices,  functional  specific  arrays,  single  gate,  dual  gate  and  standard  logic, 
amplifiers and comparators, Hall-effect and temperature sensors, power management devices including LED drivers, AC-DC and DC-
DC switching, linear voltage regulators, and voltage references along with special function devices, such as USB power switches, load 
switches, voltage supervisors and motor controllers. Our products are sold primarily throughout Asia, North America and Europe.   

On  November  24,  2015  we  acquired  Pericom  Semiconductor  Corporation.  Pericom  designs,  develops  and  markets  high-
performance  integrated  circuits  (“ICs”)  and  frequency  control  products  (“FCPs”)  used  in  many  of  today’s  advanced  electronic 
systems. ICs include functions that support the connectivity, timing and signal conditioning of high-speed parallel and serial protocols 
that  transfer  data  among  a  system’s  microprocessor,  memory  and  various  peripherals,  such  as  displays  and  monitors,  and  between 
interconnected  systems.  FCPs  are  electronic  components  that  provide  frequency  references  such  as  crystals  and  oscillators  for 
computer, communication and consumer electronic products. Analog, digital and mixed-signal ICs, together with FCPs enable higher 
system  bandwidth  and  signal  quality,  resulting  in  better  operating  reliability,  signal  integrity,  and  lower  overall  system  cost  in 
applications such as notebook computers, servers, network switches and routers, storage area networks, digital TVs, cell phones, GPS 
and  digital  media  players.  Analog,  digital  and  mixed-signal  ICs,  together  with  FCPs  enable  higher  system  bandwidth  and  signal 
quality,  resulting  in  better  operating  reliability  and  signal  integrity,  and  lower  overall  system  cost  in  applications  such  as notebook 
computers, servers, network switches and routers, storage area networks, digital TVs, cell phones, GPS and digital media players.  

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

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

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

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

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

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

including  distributor  adjustments,  which  were  approximately  $113  million,  $86  million  and  $68  million  in  2015,  2014  and  2013, 
respectively.  

Product warranty – We generally warrant our products for a period of one year from the date of sale. Historically, warranty 

expense has not been material.  

Cash,  cash  equivalents,  and  short-term  investments  –  We  consider  all  highly  liquid  investments  with  maturity  of  three 
months or less at the date of purchase to be cash equivalents. We currently maintain substantially all of our day-to-day operating cash 
balances with major financial institutions.  We hold short-term investments consisting of time deposits, which are highly liquid with 
maturity  dates  greater  than  three  months  at  the  date  of  purchase.  Generally,  we  can  access  these  investments  in  a  relatively  short 
amount  of  time  but  in  doing  so  we  generally  forfeit  a  portion  of  interest  income.    See  Note  2  below  for  additional  information 
regarding fair value of financial instruments. 

Allowance  for  doubtful  accounts  –  We  evaluate  the  collectability  of  our  accounts  receivable  based  upon  a  combination  of 
factors,  including  the  current  business  environment  and  historical  experience.  If  we  are  aware  of  a  customer’s  inability  to  meet  its 
financial obligations, we record an allowance to reduce the receivable to the amount we reasonably believe will be collected 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. Accounts receivable are presented net of valuation allowance, which were approximately $3 million in 2015 and 
$2 million 2014.  

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

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

Goodwill and other indefinite lived intangible assets – Goodwill is tested for impairment on an annual basis, on October 1, 
and between annual tests if indicators of potential impairment exist. We use the simplified goodwill impairment test, which allows us 
to  first  assess  qualitatively  whether  it  is  necessary  to  perform  step  one  of  the  two-step  annual  goodwill  impairment  test.  We  are 
required to perform step one and calculate the fair value of our reporting units only if we conclude that it is more likely than not (that 
is, a likelihood of more than 50%) that a reporting unit’s fair value is less than its carrying value. The qualitative analysis, which is 
referred to as step zero, was performed and we considered all relevant factors specific to our reporting units. Some factors considered 
in step zero were macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, events 
affecting a reporting unit and other relevant entity-specific events.  

For 2015, our step zero conclusion was that goodwill was possibly impaired at the BCD entity, located in Asia, but not impaired 
at any other entity.  For BCD, we proceeded to a step one impairment analysis and further analysis determined there was no goodwill 
impairment.  For 2014, our step zero conclusion was that it was more likely than not that goodwill was not impaired and no further 
testing  was  required  until  the  next  annual  test  date  (or  sooner  if  conditions  or  events  before  that  date  raise  concerns  of  potential 
impairment in the business) for all reporting units.   

Impairment  of  long-lived  assets  – Our long-lived assets are reviewed whenever events or changes in circumstances indicate 
that  the  carrying  value  may  not  be  recoverable.  We  consider  assets  to  be  impaired  if  the  carrying  value  exceeds  the  undiscounted 
projected cash flows from operations. If impairment exists, the assets are written down to fair value or to the projected discounted cash 
flows  from  related  operations.  As  of  December 31,  2015,  we  expect  the  remaining  carrying  value  of  assets  to  be  recoverable.  No 
impairment of long-lived assets has been identified during any of the periods presented.

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

Business combinations – The Company recognizes all (and only) the assets acquired and liabilities assumed in the transaction 
and establishes the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed in a business 
combination. Certain provisions prescribe, among other things, the determination of acquisition-date fair value of consideration paid 
in a business combination (including contingent consideration) and the exclusion of transaction and acquisition-related restructuring 
costs  from  acquisition  accounting.    During  the  normal  course  of  business  the  Company  makes  acquisitions.  In  the  event  that  an 
individual acquisition (or an aggregate of acquisitions) is material, appropriate disclosure of such acquisition activity is provided.  See 
Note 16, for additional information regarding business combinations.  

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 our assets and liabilities. If it is more likely than not that 
some portion of deferred tax assets will not be realized, a valuation allowance is recorded.  

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

Research  and  development  costs – Internally-developed research and development costs are expensed as incurred. Acquired 
in-process research and development (“IPR&D”) is capitalized as an indefinite-lived intangible asset and evaluated periodically  for 
impairment.  When  the  project  is  completed,  an  expected  life  is  determined  and  the  IPR&D  is  amortized  as  an  expense  over  the 
expected life.  

Shipping and handling costs – Shipping and handling costs for products shipped to customers, which are included in selling, 
general and administrative expenses, were approximately $8 million, $11 million and $10 million for the years ended December 31, 
2015, 2014 and 2013, respectively.  

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

We  currently  maintain  substantially  all  of  our  day-to-day  cash  balances  and  short-term  investments  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  our  financial  instruments,  including  cash  and  cash  equivalents, 
short-term  investments,  accounts  receivable,  accounts  payable,  credit  line,  and  long-term  debt  approximate  fair  value  due  to  their 
current market conditions, maturity dates and other factors.  

Earnings per  share – Basic earnings per share is calculated by dividing net earnings attributable to common stockholders by 
the  weighted-average  number  of  shares  of  Common  Stock  outstanding  during  the  period.  Diluted  earnings  per  share  is  calculated 
similarly but includes potential dilution from the exercise of stock options and stock awards, except when the effect would be anti-
dilutive. Earnings per share are computed using the “treasury stock method.”

Share-based compensation – We use the Black-Scholes-Merton model to determine the fair value of stock options on the date 
of grant and recognize compensation expense for stock options on a straight-line basis. Restricted stock grants are measured based on 
the fair market value of the underlying stock on the date of grant and compensation expense is recognized on a straight-line basis over 
the requisite four-year service period.  

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

Treasury stock – Under a program authorized by our board of directors we have purchased shares of our common stock. These 

shares are recorded as treasury stock, at cost, as a reduction to stockholder’ equity.  

Functional  currencies  and  foreign  currency  translation  –  We  translate  the  assets  and  liabilities  of  our  non-U.S.  dollar 
functional  currency  subsidiaries  into  U.S.  dollars  using  exchange  rates  on  the  balance  sheet  date.  Net  sales  and  expense  for  these 
subsidiaries  are  translated  at  the  weighted-average  exchange  rate  during  the  period  presented.  Resulting  translation  adjustments  are 
recorded as a separate component of accumulated other comprehensive income or loss within stockholders’ equity in the consolidated 
balance sheets. Included in other income are foreign exchange (gains) losses of $(1) million, $2 million and $1 million for the years 
ended December 31, 2015, 2014 and 2013, respectively.  

Defined  benefit  plan  –  We  maintain  pension  plans  covering  certain  of  our  employees  in  the  U.K.  The  overfunded  or 
underfunded status of pension and postretirement benefit plans are recognized on the balance sheet. Actuarial gains and losses, and 
prior service costs or credits, are recognized in other comprehensive  income (loss),  net  of tax effects,  until they are  amortized as a 
component  of  net  periodic  benefit  cost.  For  financial  reporting  purposes,  the  net  pension  and  supplemental  retirement  benefit 
obligations and the related periodic pension costs are calculated based upon, among other things, assumptions of the discount rate for 
plan obligations, estimated return on pension plan assets and mortality rates. These obligations and related periodic costs are measured 
using actuarial techniques and assumptions. The projected unit credit method is the actuarial cost method used to compute the pension 
liabilities and related expenses.  The expected long-term return on plan assets was determined based on historical and expected future 
returns of the various asset classes. The plan’s investment policy includes a mandate to diversify assets and invest in a variety of asset 
classes to achieve its expected long-term return and is currently invested in a variety of funds representing most standard equity and 
debt security classes. Trustees of the plan may make changes at any time.

(Table amounts in thousands except per share data)  

Investment in joint ventures – Investment in joint ventures over which we have the ability to exercise significant influence and 
that,  in  general,  are  at  least  20  percent  owned  are  accounted  for  using  the  equity  method  of  accounting.  These  investments  are 
evaluated for impairment, in which an impairment loss  would be recorded whenever a decline in the  value of an equity investment 
below its carrying amount is determined to be “other than temporary.” In judging “other than temporary,” we consider the length of 
time and extent to which the fair value of the investment has been less than the carrying amount of the investment, the near-term and 
longer-term operating and financial prospects of the investee, and our longer-term intent of retaining the investment in the investee.  

Noncontrolling interest - Noncontrolling interest (previously referred to as minority interest) primarily relates to the minority 
investors’ share of the earnings of certain China and Taiwan subsidiaries. Noncontrolling interests are a separate component of equity 
and not a liability.   Increases or decreases in noncontrolling interest, due to changes in our ownership interest of the subsidiaries that 
leave control intact, are recorded as equity transactions. The noncontrolling interest in our subsidiaries and their equity balances are 
reported separately in the consolidated financial statements, and activities of these subsidiaries are included therein.  

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

Comprehensive income (loss) – GAAP generally requires that recognized revenue, expenses, gains and losses be included in 
net  income.  Although  certain  changes  in  assets  and  liabilities  are  reported  as  separate  components  of  the  equity  section  of  the 
consolidated balance sheet, such items, along with net income, are components of comprehensive income or loss. The components of 
accumulated  other  comprehensive  income  or  loss  include  foreign  currency  translation  adjustments  and  unrealized  gain  or  loss  on 
defined  benefit  plan.  Accumulated  other  comprehensive  loss  was  approximately  $84  million,  $68  million  and  $44  million  at 
December 31, 2015, 2014 and 2013, respectively.  

There is no income tax expense or benefit associated with each component of comprehensive income. As of December 31, the 

accumulated balance for each component of comprehensive income is as follows:  

Translation adjustment ...................................................................................................... $
Unrealized loss on defined benefit plan ............................................................................ $
Unrealized foreign currency losses ................................................................................... $

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

presentation. 

Recently  Accounting  Pronouncements  -  The  Financial  Accounting  Standards  Board  (“FASB”)  issued  the  following 

Accounting Standards Updates (“ASU”) which could have potential impact to the Company’s financial statements: 

ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606).  This standard is based on the principle that revenue 
is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity 
expects  to  be  entitled  in  exchange  for  those  goods  or  services.  This  standard  also  requires  additional  disclosure  about  the  nature, 
amount,  timing  and  uncertainty  of  revenue  and  cash  flows  arising  from  customer  contracts,  including  significant  judgments  and 
changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract.  This standard is effective date in the 
first quarter of 2018 for public companies.  Under this proposal, early adoption is permitted as of the original effective time period of 
first quarter of 2017 and requires either a retrospective or a modified retrospective approach to adoption.  We have not yet selected a 
transition method and are currently evaluating the effect that the updated standard will have on our consolidated financial statements 
and related disclosures. 

ASU No. 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Cost. This 
standard requires that costs associated with the issuance of debt previously recorded as deferred assets on the balance sheet now be 
reported as a direct reduction of the related debt balance. This standard is effective for interim and annual periods beginning January 
1, 2016, but early adoption is permitted. We plan to adopt this standard in the first quarter of 2016. Upon adoption, this standard will 
be applied retrospectively to all prior periods presented. This standard will have no impact on the consolidated statements of income 
and will have an immaterial impact from the reclassifications on our consolidated balance sheets.

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

ASU No. 2015-11, Simplifying  the  Measurement  of  Inventory  (“ASU  2015-11”).   This standard requires in scope inventory to 
be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of 
business,  less  reasonably  predictable  costs  of  completion,  disposal,  and  transportation.  Subsequent  measurement  is  unchanged  for 
inventory measured using last-in, first-out (“LIFO”) or the retail inventory method.   The amendments do not apply to inventory that is 
measured using LIFO or the retail inventory method. The amendments apply to all other inventory, which includes inventory that is 
measured  using  first-in,  first-out  (“FIFO”)  or  average  cost.  The standard is  effective  for  public  business  entities  for  fiscal  years 
beginning  after  December  15,  2016,  including  interim  periods  within  those  fiscal  years and requires  prospective  application,  with 
earlier application permitted as of the beginning of an interim or annual reporting period. We are evaluating the effect that ASU 2015-
11 will have on our consolidated financial statements and related disclosures. 

ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2016-16"). This standard eliminates 
the  requirement  for  an  acquirer  to  retrospectively  adjust  the  financial  statements  for  measurement-period  adjustments  that  occur  in 
periods after a business combination is consummated. These changes become effective for fiscal years beginning after December 31, 
2015. We are evaluating the effect that ASU 2015-16 will have on our consolidated financial statements and related disclosures. 

ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes, (“ASU 2015-17”). The amendments in this update require 
that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments in this 
update  apply  to  all  entities  that  present  a  classified  statement  of  financial  position.  This  guidance  requires  that  all  deferred  tax 
liabilities and assets be classified as noncurrent on the balance sheet, and is effective for reporting periods beginning after December 
15, 2016; however, early adoption is permitted. This guidance can also be applied either prospectively to all deferred tax liabilities and 
assets or retrospectively to all periods presented. We adopted ASU 2015-17 retrospectively during the quarter ended December 31, 
2015, which resulted in the reclassification of approximately $11 million from current deferred income taxes to noncurrent deferred 
income taxes presented on the consolidated balance sheet as of December 31, 2014. 

ASU  No.  2016-01,  Financial  Instruments  -  Overall:  Recognition  and  Measurement  of  Financial  Assets  and  Financial 
Liabilities  (“ASU  2016-01”).  This  update  requires  equity  investments  (except  those  accounted  for  under  the  equity  method  of 
accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in 
net income, requires public business entities to  use the exit price notion  when  measuring the  fair value of financial instruments for 
disclosure purposes, requires separate presentation of financial assets and financial liabilities by measurement category and form of 
financial asset, and eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used 
to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. These changes become 
effective for our fiscal year beginning November 1, 2018. Early application is permitted. We are evaluating the effect that ASU 2016--
1 will have on our consolidated financial statements and related disclosures. 

ASU  No.  2016-02,  Leases  (Topic  842)  (“ASU  2016-02”)  -  The  standard  requires  companies  that  lease  valuable  assets  like 
aircraft, real estate, and heavy equipment to recognize on their balance sheets the assets and liabilities generated by contracts longer 
than a year.  The update to U.S. GAAP also requires companies to disclose in the footnotes to their financial statements information 
about the amount, timing, and uncertainty for the payments they make for the lease agreements. This new standard will be effective 
for public business entities for annual periods beginning after December 15, 2018, and interim periods therein. Early adoption will be 
permitted  for  all  entities.    We  are  evaluating  the  effect  that  ASU  2016-02  will  have  on  our  consolidated  financial  statements  and  related 
disclosures. 

Note 2 – FAIR VALUE MEASUREMENTS 

Fair  value  is  the  price  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  in  an  orderly  transaction  between 

market participants at the measurement date.  

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

These two types of inputs create a three-tier fair value hierarchy that gives the highest priority to quoted prices in active markets for 
identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:  

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

ability to access at the measurement date.  

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

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

pricing the assets or liabilities. 

As of December 31, 2015, we had short-term investments.  Trading securities held at December 31, 2014, were purchased on 
the open market and unrealized gains and losses are included in other income (expense). The trading securities are valued under the 
fair value hierarchy using Level 1 Inputs. Short-term investments of $65 million consist of investments such as time deposits, which 
are highly liquid with maturity dates greater than three months at the date of purchase. Generally, we can access these investments in a 
relatively  short  amount  of  time  but  in  doing  so  we  generally  forfeit  a  portion  of  earned  and  future  interest  income.  The  short-term 
investments are valued under the fair value hierarchy using Level 2 Inputs.  

Financial assets and liabilities carried at fair value as of December 31, 2015 are classified in the following table:

Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are 
not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when 
there  is  evidence  of  impairment).  We  believe  our  long-term  debt  under  our  revolving  credit  facility  approximates  fair  value  and  is 
valued under the fair value hierarchy using Level 2 Inputs. Financial assets and financial liabilities measured at fair value on a non-
recurring basis were not significant at December 31, 2015 and 2014. Certain non-financial assets and non-financial liabilities that are 
measured at fair value on a recurring and non-recurring basis include goodwill, other intangible assets and other non-financial long-
lived assets.

NOTE 7 – BANK CREDIT AGREEMENTS AND OTHER SHORT-TERM AND LONG-TERM DEBT  

We  maintain  credit  facilities  with  several  financial  institutions  through  our  entities  worldwide  totaling  $84  million.  In  some 

cases, our foreign credit lines are unsecured, uncommitted and may be repayable on demand.  

On  September 2,  2015,  the  Company  and  Diodes  International  B.V.  (the  “Foreign  Borrower”  and,  collectively  with  the 
Company,  the  “Borrowers”),  and  certain  subsidiaries  of  the  Company  as  guarantors,  entered  into  an  Amendment  No. 3  to  Credit 
Agreement,  Incremental  Term  Assumption  Agreement,  Limited  Waiver  and  Consent  (the  “Amendment”)  with  Bank  of  America, 
N.A.,  as  Administrative  Agent,  and  the  lenders  party  to  the  Amendment  (collectively,  the  “Lenders”),  which  amends  the  Credit 
Agreement dated January 8, 2013 (as previously amended by Amendment No. 1 to Credit Agreement and Limited Waiver dated as of 
November 1, 2013 and Amendment No. 2 to Credit Agreement and Amendment No. 1 to Collateral Agreement dated as of June 19, 
2015) (as previously amended and as amended by the Amendment, the “Credit Agreement”). 

The Amendment increases the Company’s existing senior credit facility to a $400 million revolving senior credit facility (the 
“Revolver”),  which includes  a $10 million swing line sublimit, a $10 million letter of credit sublimit, and a $20 million alternative

currency  sublimit, and a $100 million term loan facility (the “Term Loan Facility”).  We may from time to time request additional 
increases in the aggregate commitments under the Credit Agreement of up to $200 million, subject to the Lenders electing to increase 
their commitments or by means of the addition of new Lenders, and subject to at least half of each increase in aggregate commitments 
being in the form of term loans, with the remaining amount of each increase being an increase in the amount of the Revolver.  The 
Revolver and the Term Loan Facility mature on January 8, 2018 (the “Maturity Date”). The Company used a portion of the proceeds 
available under the Revolver and the Term Loan Facility to finance a portion of the purchase price for the Pericom acquisition, with 
the remaining proceeds available for working capital, for capital expenditures, and for general corporate purposes, including financing 
other permitted acquisitions. 

The  Credit  Agreement  contains  certain  financial  and  non-financial  covenants,  including,  but  not  limited  to,  a  maximum 
Consolidated  Leverage  Ratio,  a  minimum  Consolidated  Fixed  Charge  Coverage  Ratio,  and  restrictions  on  liens,  indebtedness, 
investments,  fundamental  changes,  dispositions,  and  restricted  payments  (including  dividends)  (as  such  terms  are  defined  in  the 
Amendment or the Credit Agreement).   

As  of  December 31,  2015,  our  U.S.  and  Asia  subsidiaries  had  unused  and  available  credit  lines  of  up  to  an  aggregate  of 
approximately $83 million, with several financial institutions. In some cases, our foreign credit lines are unsecured, uncommitted and 
may be repayable on demand, except for two Taiwanese credit facilities that are collateralized by assets. Our foreign credit lines bear 
interest  at  LIBOR  or  similar  indices  plus  a  specified  margin.  At  December 31,  2015,  there  were  no  amounts  outstanding  on  these 
credit lines.  

Borrower’s obligations under the Credit Agreement are secured by substantially all assets of the Borrowers and certain of their 

subsidiaries.  

Under the Revolver, the Borrowers  may borrow in United  States  Dollars (“USD”), Euros, British Pounds Sterling or another 
currency approved by the Lenders. Borrowed amounts under the Revolver and the Term Loan Facility bear interest at a rate per annum 
equal to (a) a base rate (equal to the highest of (i) the Federal Funds Rate plus 1(cid:187)2 of 1.00%, (ii) Bank of America’s “prime rate”, and 
(iii) the Eurocurrency Rate plus 1.00%,) plus 0.50% and 1.50%, based upon the Borrowers’ Consolidated Leverage Ratio, or (b) the 
Eurocurrency  Rate  plus  1.50%  and  2.50%,  based  upon  the  Borrowers’  Consolidated  Leverage  Ratio.    The  Revolver  also  bears  a 
commitment fee of 0.25% to 0.40% based on the Borrowers’ Consolidated Leverage Ratio.    

The unused and available credit under the  various  facilities as of December 31, 2015, was approximately $83  million (net of 

approximately $1 million credit used for import and export guarantee), as follows:

NOTE 9 – STOCKHOLDERS’ EQUITY  

We have never declared or paid cash dividends on our Common Stock. Our credit agreement with Bank of America N.A. and 
other lenders parties permits us to pay dividends up to $1.5 million per fiscal year to its stockholders so long as we have not defaulted 
and  are  in  continuing  operation  at  the  time  of  such  dividend.  The  payment  of  dividends  is  within  the  discretion  of  our  Board  of 
Directors. See Note 7 for additional information regarding our credit agreements.  

During November 2015 the Company’s board of directors authorized a share repurchase plan to repurchase up to an aggregate 
of  $100  million  of  the  Company’s  outstanding  common  stock,  $0.66  2/3  par  value  per  share.  The  share  repurchase  program  is 
expected to continue through  the end of 2019 unless extended or shortened by the Board of Directors.  During 2015, the Company 
repurchased 466,010 of its common shares at a cost of $11 million. All purchases were made through open market transactions and 
were recorded as treasury stock.

unrecognized  tax  positions  will  significantly  increase  or  decrease  within  the  next  12  months.  These  changes  may  be  the  result  of 
settlements of ongoing audits or competent authority proceedings.  At this time, an estimate of the range of the reasonably possible 
outcomes cannot be made.  

We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. We are no longer subject 
to  U.S.  federal  income  tax  examinations  by  tax  authorities  for  tax  years  before  2007,  or  for  the  2010  tax  year.    We  are  no  longer 
subject to China income tax examinations by tax authorities for tax years before 2005.  With respect to state and local jurisdictions and 
countries outside of the U.S., with limited exceptions, we are no longer subject to income tax audits for years before 2011. Although 
the  outcome  of  tax  audits  is  always  uncertain,  we  believe  that  adequate  amounts  of  tax,  interest  and  penalties,  if  any,  have  been 
provided for in our reserve for any adjustments that may result from future tax audits. We recognize accrued interest and penalties, if 
any,  related  to  unrecognized  tax  benefits  in  interest  expense.  We  had  an  immaterial  amount  of  accrued  interest  and  penalties  at 
December 31, 2015, 2014 and 2013.

Certain items have been reclassified in 2014 and 2013 for consistency in presentation with 2015. 

We  prospectively  adopted  ASU  No. 2013-11,  Presentation  of  an  Unrecognized  Tax  Benefit  When  a  Net  Operating  Loss 
Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, (“ASU 2013-11”) effective in the first quarter of 2014.  ASU 
No. 2013-11 provides that an entity is required to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in 
the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit 
carryforward.  The $13 million net deferred tax asset presented on the balance sheet as of December 31, 2015, is net of $5 million of 
unrecognized  tax  benefits.    The  $18  million  net  deferred  tax  asset  presented  above  is  prior  to  the  net  balance  sheet  presentation 
required  by  ASU  2013-11.    The  $44  million  net  deferred  tax  assets  presented  as  of  December  31,  2014,  is  net  of  $4  million  of 
unrecognized tax benefits.  The $48 million net deferred tax asset presented above is the net balance sheet presentation required by 
ASU 2013-11. 

At  December 31,  2015,  we  had  federal  and  state  tax  credit  carryforwards  of  approximately  $26  million  and  $7  million, 
respectively,  which are available to offset future income tax liabilities. The federal tax credit carryforwards begin to expire in 2015 
and the state tax credit carryforwards will begin to expire in 2020. We determined that it is more likely than not that a portion of our 
federal  foreign  tax  credit  and  federal  and  state  research  credit  carryforwards  will  expire  before  they  are  utilized.  The  valuation 
allowances recorded against the related deferred tax assets totaled $22 million as of December 31, 2015.  

At December 31, 2015, we had federal and state net operating loss (“NOL”) carryforwards of approximately $56 million and $3

carryforwards will be utilized; thus, no valuation allowance has been recorded. The U.S. state NOL carryforwards will begin to expire 
in 2015. We determined that it is more likely than not that the U.S. state NOL carryforwards will expire before they are fully utilized 
and  recorded  a  full  valuation  allowance  on  the  related  deferred  tax  assets.  The  foreign  NOL  carryforwards  will  begin  to  expire in 
2020. We determined that it is more likely than not that a portion of the foreign NOL carryforwards will expire before they are fully 
utilized.  The valuation allowances recorded against the related deferred tax assets totaled $2 million as of December 31, 2015..  

Supplemental Information  

Funds  repatriated  from  foreign  subsidiaries  to  the  U.S.  may  be  subject  to  federal  and  state  income  taxes.  We  intend  to 
permanently reinvest overseas all of our earnings from our foreign subsidiaries, except to the extent such undistributed earnings have 
previously  been  subject  to  U.S.  tax;  accordingly,  U.S.  taxes  are  not  being  recorded  on  undistributed  foreign  earnings.  As  of 
December 31,  2015,  we  had  undistributed  earnings  from  our  non-U.S.  operations  of  approximately  $536  million  (including 
approximately  $42  million  of  restricted  earnings  which  are  not  available  for  dividends).  Undistributed  earnings  of  our  China 
subsidiaries comprise $383 million of this total.  Additional federal and state income taxes of approximately $146 million would be 
required should the $536 million of such earnings be repatriated to the U.S. as dividends. 

The  impact  of  tax  holidays  decreased  our  tax  expense  by  approximately  $3  million,  $2  million  and  $2  million  for  the  years 
ended December 31, 2015, 2014 and 2013, respectively. The benefit of the tax holidays on both basic and diluted earnings per share 
for the years ended December 31, 2015 was approximately $0.06. The benefit of the tax holidays on both basic and diluted earnings 
per share for the years ended December 31, 2014 and 2013 was approximately $0.05.  

NOTE 11 – EMPLOYEE BENEFIT PLANS  
Defined Benefit Plan  

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

Net  period  benefit  costs  associated  with  the  defined  benefit  were  approximately  $1  million  for  each  of  the  years  ended 
December 31, 2015 and 2014. All unrecognized actuarial gains and losses, prior service costs and accumulated other comprehensive 
income are eliminated and the balance sheet liability is set equal to the funded status of the defined benefit plan at acquisition date.  

The following table summarizes the net periodic benefit costs of the plan for the years ended December 31, 2015 and 2014:

Based on an actuarial study performed as of December 31, 2015, the plan is underfunded by approximately $29 million and the 
liability  is  reflected  in  our  consolidated  balance  sheets  as  a  noncurrent  liability  and  the  amount  recognized  in  accumulated  other 
comprehensive loss was approximately $31 million. The majority of the improvement of the underfunded status in 2015 was caused 
by the change in discount rates, and partially offset by the better than expected investment returns and a decrease in future inflation 
expectations.  

We apply the  “10% corridor” approach to amortize unrecognized actuarial gains (losses). Under this approach, only actuarial 
gains  (losses)  that  exceed  10%  of  the  greater  of  the  projected  benefit  obligation  or  the  market-related  value  of  the  plan  assets  are 
amortized.  For  the  year  ended  December  31,  2015,  the  plan’s  total  recognized  loss  decreased  by  approximately  $5  million.  The 
variance between the actual and expected return to plan assets during 2015 increased the total unrecognized net loss by approximately 
$6  million.  The  total  unrecognized  net  loss  is  more  than  10%  of  the  projected  benefit  obligation  and  10%  of  the  plan  assets.  
Therefore, the excess amount will be amortized over the average term to retirement of plan participants not yet in receipt of pension, 
which  as  of  December  31,  2015  the  average  term  was  approximately  13  years.  The  following  weighted-average  assumptions  were 
used to determine net periodic benefit costs for the year ended December 31:

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

We adopted a payment plan with the trustees of the defined benefit plan, in which we will pay approximately GBP 2 million 
every  year  from 2012 through 2019. In the  first quarter of 2015, based on the pension  deficit,  we adopted (as required every three 
years) an amended payment plan in which we will pay approximately GBP 2 million (approximately $3 million based on a USD:GBP 
exchange rate of 1.6:1) annually through 2030.  

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

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

Fair value is taken to mean the bid value of securities, as supplied by the fund managers. All the plan’s securities are publically 
traded and highly liquid. The plan does not hold any Level 3 securities. See Note 2 for additional information regarding fair value and 
Levels 1, 2 and 3.  

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

We also have pension plans in Asia for which the benefit obligation, fair value of the plan assets and the funded status amounts 

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

401(k) Retirement Plan  

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

As  stipulated  by  the  regulations  of  China,  we  maintain  a  retirement  plan  pursuant  to  the  local  municipal  government  for  the 
employees in China. We are required to make contributions to the retirement plan at a rate between 10% and 22% of the employee’s 
eligible payroll. Pursuant to the Taiwan Labor Standard Law and Factory Law, we maintain a retirement plan for the employees in 
Taiwan, whereby we make contributions at a rate of 6% of the employee’s eligible payroll.  

For  the  years  ended  December 31,  2015,  2014  and  2013,  total  amounts  expensed  under  these  plans  were  approximately  $14 

million, $13 million and $6 million, respectively.

Deferred Compensation Plan  

We  maintain  a  Non-Qualified  Deferred  Compensation  Plan  (the  “Deferred  Compensation  Plan”)  for  executive  officers,  key 
employees  and  members  of  the  Board  of  Directors  (the  “Board”).  The  Deferred  Compensation  Plan  allows  eligible  participants  to 
defer the receipt of eligible compensation, including equity awards, until designated future dates. We offset our obligations under the 
Deferred Compensation Plan by investing in the actual underlying investments. These investments are classified as trading securities 
and are carried at fair value. At December 31, 2015, these investments totaled approximately $6 million. All gains and losses in these 
investments are materially offset by corresponding gains and losses in the deferred compensation plan liabilities.  

Share-Based Plans  

We maintain share-based compensation plans for our Board, officers and key employees, which provide for stock options and 

stock awards under our equity incentive plans, as described in Note 12.

Stock  Options  –  Stock options  under our 2001 Omnibus  Equity Incentive Plan (“2001 Plan”) generally  vest in equal annual 
installments  over  a  four-year  period  and  expire  ten  years  after  the  grant  date.      For  the  years  ended  December  31,  2015, 2014  and 
2013, stock option expense was approximately $3 million, $3 million and $4 million, respectively. 

In May 2013, our stockholders approved our 2013 Equity Incentive Plan (“2013 Plan”). Since the approval of the 2013 Plan, all 
stock options are granted under the 2013 Plan, and  we  will not grant any further stock options under our 2001 Plan. Stock options 
under the 2013 Plan generally vest in equal annual installments over a four-year period and expire eight years after the grant date. The 
number of shares authorized to be awarded under the 2013 Plan is 6 million shares. For additional information on the 2013 Plan, see 
our definitive proxy statement filed with the SEC.  

Share-based compensation expense for stock options granted during 2014 and 2013 was calculated on the date of grant using the 

Black-Scholes-Merton option-pricing model with the following weighted-average assumptions:

Expected volatility – We estimate expected volatility using historical volatility. Public trading volume on options in our stock is 
not  material.  As a result,  we determined that utilizing an implied volatility  factor  would not be appropriate. We calculate historical 
volatility for the period that is commensurate with the options’ expected term assumption.  

Expected term – We have evaluated expected term based on history and exercise patterns across our demographic population. 

We believe that this historical data is the best estimate of the expected term of a new option.

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

commensurate with the expected term assumption.  

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

Total  cash  received  from  option  exercises  was  approximately  $10  million,  $6  million  and  $3  million  during  2015,  2014  and 

2013, respectively.  

At  December 31,  2015,  unamortized  compensation  expense  related  to  unvested  options,  net  of  estimated  forfeitures,  was 
approximately $3 million. The weighted average period over which share-based compensation expense related to these options will be 
recognized is approximately 2 years.

The  Compensation  Committee  of  the  Board  of  Directors  reviewed  the  grants  of  stock  options  to  the  Chief  Executive  Officer 
(“CEO”) in 2009, 2010, 2011 and 2012 (each such annual grant, an “Option Grant”), and approved a Confirmation Agreement, 
dated April 1, 2013, in which we and our CEO agreed and confirmed that our CEO will assert no claim that any Option Grant in 
2009, 2010, 2011 or 2012 provided for the purchase of more than 100,000 shares of our Common Stock, and that each Option 
Grant document be deemed amended to reflect the foregoing 100,000 share limitation.

For  the  years  ended  December  31,  2015,  2014  and  2013,  share-based  compensation  expense  related  to  restricted  stock 
arrangements granted was approximately $16 million, $11 million and $9 million, respectively. Included in the restricted stock grant 
for  2015  were  724,000  shares  granted  to  Pericom  employees.  In  2015  approximately  $4  million  of  the  increase  in  restricted  stock 
expense was related to Diodes restricted stock grants issued as replacement for unvested Pericom employee awards outstanding at the 
date of the acquisition.  The total unrecognized share-based compensation expense as of December 31, 2015 was approximately $34 
million, which is expected to be recognized over a weighted average period of approximately 3 years.

NOTE 14 – SEGMENT INFORMATION AND ENTERPRISE-WIDE DISCLOSURES  

An operating segment is defined as a component of an enterprise about which separate financial information is available that is 
evaluated  regularly  by  the  chief  decision  maker,  or  decision-making  group,  in  deciding  how  to  allocate  resources  and  in  assessing 
performance. Our chief decision-making group consists of the President and CEO, Chief Financial Officer, Senior Vice President of 
Operations  and  Senior  Vice  President  of  Sales  and  Marketing.  For  financial  reporting  purposes,  we  operate  in  a  single  segment, 
standard  semiconductor  products,  through  our  various  manufacturing  and  distribution  facilities.  We  aggregate  our  different  legal 
entities  into  a  single  segment  due  to  the  products  having  similar  economic  characteristics,  being  similar  in  production  process  and 
manufacture flow, and sharing the same customers and target end-equipment markets.

The  accounting  policies  of  the  operating  entities  are  the  same  as  those  described  in  the  summary  of  significant  accounting 

policies.  

Geographic Information - Historically, we reported net sales “billed to” customers located in various countries. In 2013, we 
changed  to  net  sales  “shipped  to”  customer  locations  as  we  believe  the  change  better  represents  where  our  customers  business 
activities occur. All years presented reflect this change.

Purchase  commitments  –  We  have  entered  into  non-cancelable  purchase  contracts  for  capital  expenditures,  primarily  for 

manufacturing equipment, for approximately $25 million at December 31, 2015.  

Contingencies  -  From time to time, we are involved in various legal proceedings that arise in the normal course of business. 
While  we  intend  to  defend  any  lawsuit  vigorously,  we  presently  believe  that  the  ultimate  outcome  of  any  current  pending  legal 
proceeding will not have any material adverse effect on our financial position, cash flows or operating results. However, litigation is 
subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which 
could impact on our business and operating results for the period in which the ruling occurs or future periods.  Based on information 
available, we evaluate the likelihood of potential outcomes. We record the appropriate liability when the amount is deemed probable 
and reasonably estimable. In addition, we do not accrue for estimated legal fees and other directly related costs as they are expensed as 
incurred.  Legal proceedings that we believe are material are disclosed below.  

On September 15, 2014, the United States District Court for the Eastern District of Texas issued an order regarding the putative 
securities class action entitled Local 731 I.B. of T. Excavators and Pavers Pension Trust Fund v. Diodes, Inc., Civil Action No. 6:13-
cv-00247 (E.D. Tex. filed Mar. 15, 2013) (the “Class Action”), granting defendants’ motion to dismiss the Class Action with prejudice. 
On October 13, 2014, plaintiffs filed a notice of appeal to the order dismissing the Class Action to the United States Court of Appeals 
for  the  Fifth  Circuit.  On  January  13,  2016,  the  Court  of  Appeals  issued  an  order  and  opinion  affirming  the  dismissal  of  the  Class 
Action  with  prejudice.   Plaintiffs-appellants  have  until  April  12,  2016  to  file  a  petition  for  a  writ  of  certiorari  to  the  United  States 
Supreme Court.  Defendants-respondents intend to continue defend this action vigorously.  

On February 20, 2014, a purported stockholder derivative  action  was  filed in the United States District Court for the Eastern 
District of Texas, entitled Persson v. Keh-Shew Lu, Case No. 4:14-cv-00108-RC-ALM (E.D. Tex. filed Feb. 20, 2014), on behalf of 
the Company against its directors, in which plaintiff alleges that the Board breached their fiduciary duties by allowing the Company to 
make allegedly misleading public statements in 2011 regarding the labor market in China and its impact on the Company’s business 
and prospects, by failing to maintain internal controls and by selling shares of Diodes stock while allegedly in possession of material 
nonpublic information regarding the labor market in China and its impact on the Company’s business and prospects. The complaint 
does not seek any damages or other relief from the Company.  On April 17, 2014, the Court granted the parties’ unopposed motion to 
stay this action until such time that the Court rules on defendants’ motion to dismiss in the Class Action.  On October 2, 2014, the 
Court granted the parties’  unopposed motion to extend the stay of this action  until 30 days after either the expiration of the appeal 
period  or  a  final  decision  by  the  highest  court  of  appeals  regarding  the  defendants’  motion  to  dismiss  in  the  Class  Action.   The 
defendants intend to defend the action vigorously.

NOTE 16 – BUSINESS COMBINATION  

Pericom Semiconductor Corporation 

On  November  24,  2015,  we  completed  our  acquisition  of  Pericom  Semiconductor  Corporation  (“Pericom”)  pursuant  to  the 
Agreement  and  Plan  of  Merger  dated  as  of  September  2,  2015  (the  “Merger  Agreement”),  as  amended  on  November  6,  2015,  by 
Amendment  No.  1  (the  “Merger  Agreement  Amendment”).  Under  the  Merger  Agreement  and  the  Merger  Agreement  Amendment 
and in accordance with the General Corporation Law of the State of California (1) PSI Merger Sub, Inc., a California corporation and 
wholly-owned subsidiary of the Company, was merged with and into Pericom, with Pericom continuing as the surviving corporation 
and  a  wholly-owned  subsidiary  of  the  Company,  and  (2)  each  outstanding  share  of  common  stock,  without  par  value,  of  Pericom 
(other  than  shares  owned  by  Pericom  or  certain  of  its  affiliates  or  shares  held  by  Pericom  shareholders  who  have  perfected  their 
appraisal rights in accordance with applicable California law) was automatically converted into the right to  receive $17.75 in cash per 
share,  without interest.  The aggregate consideration  was approximately $403 million including the value of Pericom equity awards 
paid out or converted to Diodes equity awards pursuant to the Merger Agreement and Merger Agreement Amendment.   

The table below sets forth the estimated purchase price and related costs for Pericom: 

Cash consideration for shares outstanding ...................................................................................................................    $

The  results  of  operations  of  Pericom  are  included  in  our  consolidated  financial  statements  from  November  24,  2015.    The 
consolidated revenue and earnings of Pericom included in our consolidated financial statements for the year ended December 31, 2015 
was approximately $15 million and $(1) million, respectively, which include acquisition accounting adjustments.  The purpose of the 
acquisition was to further our strategy of expanding market and growth opportunities through selected strategic acquisitions.

Under the acquisition accounting guidelines we were required to record all assets acquired and liabilities assumed at fair value, 
and recognize intangible assets and goodwill of the acquired business. The table below sets forth the preliminary fair value assigned to 
the assets and liabilities acquired in the Pericom acquisition.  This preliminary purchase price allocation has been used to prepare pro 
forma adjustments in the pro forma condensed combined balance sheet and statements of earnings. U.S. GAAP permits companies to 
complete  the  final  determination  of  the  fair  values  of  assets  and  liabilities  up  to  one  year  from  the  acquisition  date.  The  size  and 
breadth of the Pericom acquisition  will  necessitate the use of this one  year  measurement period to adequately analyze and assess a 
number  of  the  factors  used  in  establishing  the  asset  and  liability  fair  values  as  of  the  acquisition  date  including  (i)  changes  in  fair 
values of fixed assets and inventories, (ii) changes in allocations of intangible assets such as trademarks and in process research and 
development and developed technology, as well as goodwill, and (iii) other changes to assets and liabilities. The final allocation may 
also result in changes to amortization periods assigned to the assets. Any potential adjustments made could be material in relation to 
the preliminary values. A final determination of the allocation of the purchase price to the assets acquired and liabilities assumed has 
not been completed and the following table is considered preliminary.

The fair value of the significant identified intangible assets was estimated by using the market approach, income approach and 
cost approach valuation methodologies. Inputs used in the methodologies primarily included projected future cash flows, discounted at 
a rate commensurate with the risk involved. The total amount of intangible assets acquired subject to amortization expense was $141 
million, with a weighted-average amortization period 11.6 years.  We also acquired approximately $11 million of in process research 
and  development.  Goodwill  arising  from  the  acquisition  is  attributable  to  future  income  from  new  customer  contracts,  synergy  of 
combined operations, the acquired workforce and future technology that has yet to be designed or even conceived.   

We  estimated  the  fair  value  of  acquired  receivables  to  be  $23  million  with  a  gross  contractual  amount  of  $25  million.  We 
expected to collect substantially all of the acquired receivables. We evaluated and adjusted the acquired inventory  for a reasonable 
profit  allowance,  which  is  intended  to  permit  us  to  report  only  the  profits  normally  associated  with  the  activities  following  the 
acquisition  as  it  relates  to  the  work-in-progress  and  finished  goods  inventory.  As  such,  we  increased  fair  value  of  the  inventory 
acquired from Pericom by approximately $6 million.  Subsequent to the closing date of the acquisition we expensed that increase into 
cost of goods sold, of which approximately $3 million was recorded in the fourth quarter of 2015 and $3 million will be recorded in 
the first quarter of 2016 as the acquired work-in-progress and finished goods inventory is sold.

The unaudited pro forma consolidated results of operations do not purport to be indicative of the results that would have been 
obtained if the above acquisition had actually occurred as of the dates indicated or of those results that may be obtained in the future. 
The unaudited proforma consolidated results for December 31, 2015, exclude $10 million of acquisition related costs and $8 million 
of  costs  from  Diodes  restricted  stock  grants  and  change-in-control  agreements  for  Pericom  employees,  and  include  additional 
amortization  and  depreciation  of  $12  million,  additional  interest  expense  of  $11  million  and  additional  income  tax  expense  of  $1 
million. These unaudited pro forma consolidated results of operations were derived, in part, from the historical consolidated financial 
statements of Pericom and other available information and assumptions believed to be reasonable under the circumstances.  Pericom 
will be conformed to Diodes’ reporting calendar.   

BCD Semiconductor Manufacturing Limited  

On March 5, 2013, we completed the acquisition of all the outstanding ordinary shares, par value $0.001 per share, of BCD (the 
“Shares”), including Shares represented by American Depository Shares (“ADSs”), which were cancelled in exchange for the right to 
receive $1.33-1/3 in cash per Share,  without interest. Each ADS represented six Shares  and  was converted into the right  to receive 
$8.00  in  cash,  without  interest.  The  aggregate  consideration  was  approximately  $155  million,  excluding  acquisition  costs,  fees and 
expenses.  In  addition,  a  $5  million  retention  plan  for  BCD  employees,  payable  at  the  12,  18  and  24  month  anniversaries  of  the 
acquisition, was established. The employee retention plan was intended to benefit us and not the selling shareholders, and therefore 
was excluded from the determination of the purchase price. The acquisition was funded by drawings on our revolving senior credit 
facility. The purchase price for BCD and related costs were estimated as follows:  

Purchase price (cost of shares) ...........................................................................................................................  
Acquisition related costs (included in selling, general and   administrative expenses) ......................................  
Total purchase price ...........................................................................................................................................

The results of operations of BCD are included in the consolidated financial statements from March 1, 2013. The consolidated 
revenue  and  earnings  of  BCD  included  in  our  consolidated  financial  statements  for  the  year  ended  December 31,  2013  were 
approximately  $155  million  and  $6  million,  respectively,  which  include  acquisition  accounting  adjustments.  The  purpose  of  the 
acquisition was to further our strategy of expanding market and growth opportunities through select strategic acquisitions.  

Under the accounting guidance for step acquisitions, we were required to record all assets acquired and liabilities assumed at fair 
value, and recognize goodwill of the acquired business. The step acquisition guidelines also require us to remeasure the preexisting 
investment  in  BCD  at  fair  value,  and  recognize  any  gains  or  losses  from  such  remeasurement.  The  fair  value  of  our  interest 
immediately  before  the  closing  date  was  $7  million,  which  resulted  in  us  recognizing  a  non-cash  gain  of  approximately  $4  million 
within other income (expense) for the year ended December 31, 2013. The shares of BCD common stock were valued under the fair 
value hierarchy as a Level 1 Input.

The fair value of the significant identified intangible assets was estimated by using the market approach, income approach and 
cost approach valuation methodologies. Inputs used in the methodologies primarily included projected future cash flows, discounted at 
a rate commensurate with the risk involved. The total amount of intangible assets acquired subject to amortization expense was $17 
million,  which  had  a  residual  value  of  zero  and  weighted-average  amortization  period  of  6 years.  Goodwill  arising  from  the 
acquisition is attributable to future income from new customer contracts, synergy of combined operations, the acquired workforce and 
future technology that has yet to be designed or even conceived. In addition, goodwill is not deductible for income tax purposes.  

We  estimated  the  fair  value  of  acquired  receivables  to  be  $21  million  with  a  gross  contractual  amount  of  $21  million.  We 
expected to collect substantially all of the acquired receivables. We evaluated and adjusted the acquired inventory  for a reasonable 
profit  allowance,  which  is  intended  to  permit  us  to  report  only  the  profits  normally  associated  with  the  activities  following  the 
acquisition as it relates to the work-in-progress and finished goods inventory. As such, we increased the inventory acquired from BCD 
by approximately $5 million, and recorded that increase into cost of goods sold, of which approximately $2 million was recorded in 
the  first  quarter  of  2013  and  $3  million  was  recorded  in  the  second  quarter  of  2013  as  the  acquired  work-in-progress  and  finished 
goods inventory was sold.  

The following unaudited pro forma consolidated results of operations for the year ended December 31, 2013 have been prepared

***  Confidential treatment has been requested with respect to the omitted portions of these exhibits, which portions have been filed 

separately with the Securities and Exchange Commission.  

****  A certification furnished pursuant to Item 601 of the Regulation S-K will not be deemed “filed” for purposes of Section 18 of 
the  Securities  Exchange  Act  of  1934,  as  amended  (the  “Exchange  Act”),  or  otherwise  subject  to  the  liability  of  that  section. 
Such  certification  will  not  be  deemed  to  be  incorporated  by  reference  into  any  filing  under  the  Securities  Act  of  1933,  as

PLEASE NOTE: It is inappropriate for investors to assume the accuracy of any covenants, representations or warranties that may be 
contained in agreements or other documents filed as exhibits to this Annual Report on Form 10-K. In certain instances the disclosure 
schedules to such agreements or documents contain information that modifies, qualifies and creates exceptions to the representations, 
warranties and covenants. Moreover, some of the representations and warranties may not be complete or accurate as of a particular 
date because they are subject to a contractual standard of materiality that is different from those generally applicable to stockholders or 
were  used  for  the  purpose  of  allocating  risk  among  the  parties  rather  than  establishing  certain  matters  as  facts.  Accordingly,  you 
should not rely on the representations and  warranties as characterizations of the actual  state of  facts at the time they  were  made or 
otherwise.

ADJUSTED NET INCOME AND ADJUSTED EARNINGS PER SHARE

This consists of accounting principles generally accepted in the United States (“GAAP”) net income and earnings per share attributable to common
stockholders, which are then adjusted for the purpose of providing investors with a better depiction of the Company’s operating results and provide a
more informed baseline for modeling future earnings expectations. The Company makes adjustments for amortization of acquisition related
intangible assets, acquisition costs, restructuring costs, severance costs, tax expense related to tax audit, inventory adjustments and valuations,
retention costs, impairment of goodwill, gain on sale of assets, amortization of debt discount, impairment of long-lived assets, and employee award
costs. The Company excludes the above items to evaluate the Company’s operating performance, develop budgets, and manage cash expenditures.
Presentation of the above non-GAAP measures allows investors to review the Company’s results of operations from the same viewpoint as the
Company’s management and Board of Directors. The Company has historically provided similar non-GAAP financial measures to provide investors
an enhanced understanding of its operations, facilitate investors’ analyses and comparisons of its current and past results of operations and provide
insight into its future performance. The Company also believes the non-GAAP measures are useful to investors because they provide additional
information that research analysts use to evaluate semiconductor companies. These non-GAAP measures should be considered in addition to results
prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results and may differ from measures used by
other companies. The Company recommends a review be performed on net income and earnings per share on both a GAAP and non-GAAP basis to
obtain a comprehensive view of the Company’s results. The Company provides a reconciliation of GAAP net income and GAAP earnings per share
to non-GAAP adjusted net income and non-GAAP adjusted earnings per share.

Detail of non-GAAP adjustments

Amortization of acquisition related intangible assets – The Company excluded this item, including developed technologies and customer
relationships. The fair value of the acquisition related intangible assets, which was recognized through purchase accounting, is amortized using
straight-line methods which approximate the proportion of future cash flows estimated to be generated each period over the estimated useful lives of
the applicable assets. The Company believes the exclusion of this item is appropriate because a significant portion of the purchase price for its
acquisitions was allocated to the intangible assets that have short lives and exclusion of the amortization expense allows comparisons of operating
results that are consistent over time for both the Company’s newly acquired and long-held businesses. In addition, the Company excluded this item
because there is significant variability and unpredictability among companies with respect to this expense.

Acquisition costs – The Company excluded these costs associated with acquiring Pericom and BCD, which consisted of advisory, legal and other
professional and consulting fees. These costs were expensed in 2015, 2013 and 2012 when the costs were incurred and services were received, and
which the corresponding tax adjustments were made for the non-deductible portions of these expenses. The Company believes the exclusion of this
item provides investors an enhanced view of certain costs the Company may incur from time to time and facilitates comparisons with the results of
other periods that may not reflect such costs.

Restructuring costs – The Company recorded restructuring charges to reduce its cost structure in order to enhance operating effectiveness and
improve profitability. These restructuring activities related to our UK development team and the closure of our New York sales office. These charges
are excluded from management’s assessment of the Company’s operating performance. The Company believes the exclusion of this item provides
investors an enhanced view of the cost structure of the Company’s operations and facilitates comparisons with the results of other periods that may
not reflect such charges or may reflect different levels of such charges.

Severance costs – The Company excluded severance costs incurred during 2015. These one-time costs will reduce the Company’s cost structure in order to
enhance operating effectiveness and improve profitability. These charges are excluded from management’s assessment of the Company’s operating
performance. The Company believes the exclusion of the severance charges provides investors an enhanced view of the cost structure of the Company’s
operations and facilitates comparisons with the results of other periods that may not reflect such charges or may reflect different levels of such charges.

Tax expense related to tax audit – The China government audited the Company’s High and New Technology Enterprise (“HNTE”) status for the
years 2009 through 2013 and determined there was an underpayment for the tax year 2013. The Company was approved for the HNTE status for
2012 through 2014. Given that 2013 is an isolated occurrence, the additional tax associated with the audit is excluded. The Company believes the
exclusion of this item provides investors an enhanced view of certain costs the Company may incur from time to time and facilitates comparisons
with the results of other periods that may not reflect such costs.

Inventory adjustments and valuations – In 2015 and 2013, the Company adjusted the inventory acquired in the Pericom and BCD acquisitions to
account for the reasonable profit allowance for the selling effort on finished goods inventory and the reasonable profit allowance for the completing
and selling effort on the work–in-progress inventory. This non-cash adjustment to inventory is not recurring in nature; however it could be recurring
to the extent there are additional acquisitions. The Company believes the exclusion of the Pericom and BCD inventory adjustments and valuations
provides investors with a more accurate reflection of costs likely to be incurred in the absence of an unusual event such as an acquisition and
facilitates comparisons with the results of other periods that may not reflect such costs.

Retention costs – The Company excluded costs related to the employee retention plans in connection with the Pericom and BCD acquisitions.
Although these retention costs will be recurring every quarter until the final retention payment has been made, they are not part of the employees’
normal annual salaries and therefore are being excluded. The Company believes the exclusion of retention costs related to the acquisitions provides
investors with a more accurate reflection of costs likely to be incurred in the absence of an unusual event such as an acquisition and facilitates
comparisons with the results of other periods that may not reflect such costs.

Impairment of goodwill – The Company recorded a non-cash goodwill impairment charge related to the Eris acquisition. This charge is excluded
from management’s assessment of the Company’s operating performance. The Company believes the exclusion of this item provides investors an
enhanced view of certain non-cash charges the Company’s may incur from time to time and facilitates comparisons with the results of other periods
that may not reflect such charge. Since the Company owns approximately 51% of Eris, it took into account the noncontrolling interest of Eris and
only excluded its portion of the impairment as it relates to net income.

Gain on sale of assets – During 2014, the Company sold a building located in Taiwan and this gain was excluded from management’s assessment of the
Company’s core operating performance. The Company believes the exclusion of the gain on sale of assets provides investors an enhanced view of a gain the
Company may incur from time to time and facilitates comparisons with results of other periods that may not reflect such gains. During 2012, the Company
sold an intangible asset located in Europe and this gain was excluded from management’s assessment of the Company’s core operating performance as this
long-lived asset was a non-core intellectual asset. Also, during 2012, the Company sold a building located in Taiwan and this gain was excluded from
management’s assessment of the Company’s core operating performance. The Company believes the exclusion of these items provides investors an
enhanced view of a gain the Company may incur from time to time and facilitates comparisons with results of other periods that may not reflect such gains.

Amortization of debt discount – The Company excluded the amortization of debt discount on its 2.25% Convertible Senior Notes (“Notes”). This
item was excluded from management’s assessment of the Company’s core operating performance. Although this item is recurring in nature, the
expected life of the Notes was five years as that is the earliest date in which the Notes could be put back to the Company at par value. The
amortization period ended October 1, 2011, therefore the Company no longer records amortization of debt discount. In addition, the Company
repurchased some of its Notes, which made the principal amount outstanding and related amortization vary from period to period, and as such the
Company believes the exclusion of this item facilitates comparisons with the results of other periods that may reflect different principal amounts
outstanding and the related amortization.

Impairment of long-lived assets – During 2015, the Company excluded costs accrued for impairment of long-lived assets related to assets that will
no longer be used in our production process as we transition from six inch to eight inch production capability in our China wafer plant. The Company
believes the exclusion of this item provides investors an enhanced view of a loss the Company may incur from time to time and facilitates
comparisons with results of other periods that may not reflect such impairments.

Employee award costs – As part of the Pericom acquisition, the Company incurred costs for stock awards and change-in-control agreements for
Pericom employees. The Company believes the exclusion of employee award costs related to the Pericom acquisition provides investors with a more
accurate reflection of costs likely to be incurred in the absence of an unusual event such as an acquisition and facilitates comparisons with the results
of other periods that may not reflect such costs.
