may  read  and  copy  any  material  we  file  with  the  SEC  at  the  SEC’s  Public  Reference  Room  at  100 F Street  NE,  Room 1580, 
Washington, D.C. 20549. You may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-
SEC-0330. The SEC also  maintains an Internet site that  contains reports, proxy, and information statements, and other information 
regarding registrants that file electronically with the SEC at www.sec.gov. 

We  are  a  premier  intellectual  property  and  technology  licensing  company  focusing  on  the  creation,  design,  development  and 
licensing  of  patented  innovations,  technologies  and  architectures  that  are  foundational  to  nearly  all  digital  electronics  products  and 
systems. Our mission is to continuously enrich the end-user experience of electronic systems through groundbreaking innovations and 
technologies  designed  to  improve  the  performance,  power  efficiency,  time-to-market  and  cost-effectiveness  of  the  products, 
components  and  systems  offered  by  market-leading  companies  in  semiconductors,  computing,  tablets,  handheld  devices,  mobile 
applications,  gaming  and  graphics,  high  definition  televisions,  or  HDTVs,  and  displays,  general  lighting,  cryptography  and  data 
security.  Our  inventors  and  engineering  teams  focus  on  creating  innovations  designed  to  address  the  most  challenging  demands  of 
each target market and industry.  

We  generate  revenue  by  licensing  our  patented  innovations  and  technologies  to  market-leading  companies  that  provide  their 
products  to  the  end-user  customers  or  consumers.  We  believe  we  have  established  an  unparalleled  licensing  platform  and  business 
model that will continue to foster the development of new foundational and leading innovations and technologies. By continuing to 
build  upon  this  platform,  our  goal  is  to  create  additional  licensing  opportunities,  and  thereby  perpetuate  strong  company  operating 
performance and long-term stockholder value.  

While we have historically focused our efforts in the development of technologies for electronics memory and chip interfaces, we 
have  been  expanding  our  portfolio  of  inventions  and  solutions  to  address  additional  markets  in  lighting,  displays,  chip  and  system 
security, digital media, as well as new areas within the semiconductor industry, such as imaging and non-volatile memory. We intend 
to continue our growth into new technology fields, consistent with our mission to create great value through our innovations and to 
make those technologies available through our licensing business model. Key to our efforts, both in our current businesses and in any 
new  area  of  diversification,  will  be  hiring  and  retaining  world-class  inventors,  scientists  and  engineers  to  lead  the  development  of 
inventions  and  technology  solutions  for  these  fields  of  focus,  and  the  management  and  business  support  personnel  necessary  to 
execute our plans and strategies. 

Rambus  has  two  business  groups:  the  Semiconductor  Business  Group,  or  SBG,  which  focuses  on  the  design,  development  and 
licensing  of  technology  that  is  semiconductor  based,  and  the  New  Business  Group,  or  NBG,  which  focuses  on  the  design, 
development and licensing of technologies for lighting, displays, chip and system security, anti-counterfeiting, digital media and other 
markets.  

As  of  December  31,  2011,  our  semiconductor,  lighting,  display,  security  and  other  technologies  are  covered  by  1,386  U.S.  and 
foreign  patents.  Additionally,  we  have  1,059  patent  applications  pending.  Some  of  the  patents  and  pending  patent  applications  are 
derived  from  a  common  parent  patent  application  or  are  foreign  counterpart  patent  applications.  We  have  a  program  to  file 
applications for and obtain patents in the United States and in selected foreign countries where we believe filing for such protection is 
appropriate  and  would  further  our  overall  business  strategy  and  objectives.  In  some  instances,  obtaining  appropriate  levels  of 
protection  may  involve  prosecuting  continuation  and  counterpart  patent  applications  based  on  a  common  parent  application.  We 
believe  that  our  patented  innovations  provide  our  customers  means  to  achieve  improved  performance,  lower  risk,  greater  cost-
effectiveness and other benefits in their products and services. 

Our  patented  inventions  and  technology  solutions  are  offered  to  our  customers  through  either  a  patent  license  or  a  solutions 
license.  Our  revenues  are  primarily  derived  from  patent  licenses,  through  which  we  provide  our  customers  a  license  to  use  some 
specified portion of our broad portfolio of patented inventions. The patent license essentially provides our customers with a defined 
right to use our patented innovations in the customer’s own digital electronics products, systems or services, as applicable. The patent 

8 

 
 
 
 
 
 
 
 
 
 
 
licenses  may  also  define  the specific field of use  where our  customers may  employ  our  inventions  in  their products.  Patent  license 
agreements are structured with fixed, variable or a hybrid of fixed and variable royalty payments over certain defined periods. 

We also offer our customers solutions licenses to support the implementation and adoption of our technology in their products or 
services.  Our  solutions  license  offerings  include  a  range  of  solutions  developed  by  Rambus,  which  include  “leadership”  solutions 
(which  are  Rambus-proprietary  solutions  widely  licensed  to  our  customers)  and  industry-standard  solutions  that  we  provide  to  our 
customers under license for incorporation into our customers’ digital electronics products and systems. We offer a range of services as 
part  of  our  solutions  licenses  which  can  include  know-how  and  technology  transfer,  product  design  and  development,  system 
integration,  supply  chain  consulting  and  other  services.  These  solutions  license  agreements  may  have  both  a  fixed  price  (non-
recurring) component and ongoing royalties. Further, under solutions licenses, our customers typically receive licenses to our patents 
necessary  to  implement  these  solutions  in their  products  with  specific  rights  and  restrictions  to  the applicable patents  elaborated in 
their individual contracts with us. 

Background 

Semiconductor Technology 

The demand for increased performance in computers, tablets, smartphones, consumer electronics and other electronic systems rises 
dramatically with each passing year. Semiconductor and system designers face key challenges in sustaining this pace of innovation. 
Since  battery  technology  improves  modestly  over  time,  mobile  device  designers  face  adding  increased  functionality  and  higher 
performance with only small increases in power budget. For plug-in systems, there is a strong desire to reduce power consumption for 
both economic and environmental reasons while still providing increased computing capability and more visually compelling displays. 
At  the  chip  level,  it  becomes  increasingly  difficult  to  maintain  signal  integrity  and  power  efficiency  as  data  transfer  speeds  rise  to 
support more powerful, multi-core processors.  

To address these challenges and enable the continued improvement of electronics systems requires ongoing innovation. The many 
contributions  and  patented  innovations  developed  by  Rambus’  scientists  and  engineers  have  been,  and  continue  to  be,  critical  in 
addressing some of the most difficult chip and system challenges. We have developed what we believe are the world’s fastest memory 
solutions  delivering  breakthrough  performance  at  unmatched  power  efficiency.  Our  patented  innovations  can  deliver  the  memory 
bandwidth and throughput needed to unleash the potential of multi-core processors.  

Lighting and Display Technology  

The continued evolution of the LED as a bright, reliable and energy-efficient light source creates significant market opportunities in 
consumer  electronics  and  in  general  lighting.  Harnessing  the  benefits  of  LEDs,  however,  presents  a  new  set  of  challenges  for 
companies that offer and provide electronics and lighting products and solutions. Since LED backlighting solutions are increasingly 
pervasive  in  liquid  crystal  displays,  or  LCDs,  for  computers,  smartphones,  tablets,  game  systems,  HDTVs  and  any  user  interface 
incorporating  an  active  display,  the  continued  move  to  higher  resolution  displays  across  these  products  requires  more  LEDs  per 
system. The increased usage of LEDs is thereby creating a need for increased power efficiency since the LED backlight is the primary 
source of power consumption in many consumer electronics products, including smartphones. While LEDs may offer the promise of 
long operating life, energy efficiency and improved aesthetics, there are significant technical challenges with the adoption of LEDs 
that relate to their comparatively high cost, illumination effectiveness and design and form factor constraints. These challenges present 
a significant market opportunity for Rambus. 

We believe that our patented innovations in lighting and display technologies represent significant value to applications, products 
and  systems  that  use  or  will  adopt  LED-based  lighting.  For  example,  our patented  innovations  in backlighting  can  enable  what we 
believe  to  be  some  of  the  thinnest,  most  power-efficient  and  cost-effective  LCD  displays  for  smartphones,  tablets,  computers  and 
HDTVs.  In  addition,  our  goal  is  that  our  patented  innovations  and  technologies  in  general  lighting  will  offer  revolutionary  and 
breakthrough  solutions  that  will  provide  exceptional  quality  and  control  of  illumination  in  form  factors  unconstrained  by  legacy 
lighting  products  and  systems.  We  believe  that  these  breakthrough  patented  innovations  and  technologies  advance  our  mission  of 
enriching the consumer experience of electronic products and systems and represent additional significant licensing opportunities in 
growing markets. We continue to focus significant resources and effort to help bring these new products to market under solutions 
license agreements with leading companies in the industry.

Chip and System Security Technology  

As  electronics  systems  grow  increasingly  sophisticated,  the  information  and  data  stored  and  transferred  through  these  devices 
increases in value. For example, smartphones and game systems store personal data, conduct financial transactions and e-commerce, 
and  deliver  copyrighted  content  including  movies,  music  and  games.  Unless  these  systems  can  be  made  reliably  secure,  their 
usefulness  to  consumers  and  content  owners  decreases  dramatically.  Examples  of  high  profile  security  breaches  of  electronics 
products and systems clearly illustrate the critical importance of data and information security. Security is also a significant risk and 
concern for companies that offer branded accessories and consumables, such as printing peripherals and consumable inks. Counterfeit 
products have the effect of decreasing earning potential, damaging a company’s brand image and exposing consumers to low quality 
or defective goods. Proper security measures may be used to effectively eliminate certain types of counterfeiting through the use of 
encryption related technologies.  

Through our acquisition of CRI, we own a portfolio of patented inventions and technology solutions that we believe provide an 
unrivaled  level  of  security  in  electronic  devices  and  systems.  CRI’s  patented DPA  countermeasures are  critical  in designing  secure 
semiconductors and products, and are used to protect devices against side channel attacks such as monitoring the variations in power 
consumption  or  electromagnetic  emissions  of  a  device.  In  addition,  CRI’s  CryptoFirewall  cores  provide  a  robust  hardware-based 
solution to protect electronics systems from the full range of attacks. We believe our hardware level security is vastly superior to many 
software-based security solutions, and provides a robust platform for building effective security applications. 

Additional Technologies 

Consistent  with  our  mission  of  continuously  enriching  the  end-user  experience  of  electronic  systems,  Rambus’  scientists  and 
engineers are focusing on inventing, developing and expanding our patented innovations and solutions into new technology areas. As 
electronic systems continue their rapid evolution, new opportunities for innovation abound, which offer new avenues for licensing and 
long-term growth.  

Our Offerings 

Patented Innovations 

Royalties represent a substantial majority of our total revenue. We derive the majority of our royalty revenue by licensing our broad 
portfolio of patents to our customers. These licenses may cover part or all of our patent portfolio across our breadth of technologies. 
Leading  semiconductor  and  system  companies  such  as  AMD,  Broadcom,  Elpida,  Freescale,  Fujitsu,  Intel,  Panasonic,  Renesas, 
Samsung  and  Toshiba  have  licensed  our  patents  for  use  in  their  own  products.  Examples  of  the  many  patented  innovations  in  our 
portfolio include, and have included: 

Dual  Edge  Clocking  which  is  designed  to  allow  data  to  be  sent  on  both  the  leading  and  trailing  edge  of  the  clock  pulse, 

effectively doubling the transfer rate out of a memory core without the need for higher system clock speeds.

In  our  semiconductor  business,  we  also  offer  industry-standard  chip  interface  solutions,  including  DDRx  (where  the  “x”  is  a 

number that represents a version), as well as digital logic controllers for PCI Express and other industry standard interfaces.  

Design and Manufacturing 

Our  technology  solutions  are  developed  with  high-volume  commercial  manufacturing  processes  in  mind.  Our  solutions  can  be 
delivered in a number of ways, from reference designs to full turnkey custom developments. A reference design engagement might 
include an architectural specification, data sheet, theory of operation and implementation guides. A custom development would entail 
a  specific  design  implementation  optimized  for  the  licensee’s  manufacturing  process.  In  some  cases,  we  may  provide  supply  chain 
enablement services where we assist our customers in designing and establishment of certain manufacturing processes to implement 
our technologies in their product offerings.  

Target Markets, Applications and Customers 

We work with leading and emerging semiconductor and digital electronics products and system customers to enable their products 
and services. We engage with our customers across the entire product life cycle, from system architecture development, to component 
design,  to  system  integration,  to  production  ramp-up  through  product  maturation.  Our  patented  innovations  and  technologies  are 
incorporated into a broad range of high-volume applications in computing, gaming and graphics, lighting, consumer electronics, and 
mobile  markets.  System  level  products  that  utilize  our  patented  inventions  and/or  solutions  include  smartphones,  tablets,  personal 
computers,  servers,  printers,  video  projectors,  game  systems,  HDTVs,  TV  set-top  boxes  and  LED-based  lighting  offered  by  such

Our Strategy 

The key elements of our strategy are as follows:  

Innovate:  Develop and patent our innovative technology to provide fundamental competitive advantage when incorporated into 

semiconductors, and digital electronics products and systems. 

Drive Adoption:  Communicate the advantages of our patented innovations and technologies to the industry and encourage its 

adoption through demonstrations and incorporation in the products of select customers. 

Monetize:  License  our  patented  inventions  and  technology  solutions  to  customers  for  use  in  their  semiconductor  and  system 

products. 

We believe that the successful execution of this strategy requires an exceptional and unparalleled licensing platform and business 
model  that  relies  on  the  skills  and  talent  of  our  employees.  Accordingly,  we  seek  to  hire  and  retain  world  class  scientific  and 
engineering expertise in all of our fields of technological focus, as well as the executive management and operating personnel required 
to successfully execute our business strategy. In order to attract the quality of employees required for this business model, we have 
created  an  environment  and  culture  that  encourages,  fosters  and  supports  research,  development  and  innovation  in  breakthrough 
technologies  with  significant  opportunities  for  broad  industry  adoption  through  licensing.  We  believe  that  we  have  created  a 
compelling  company  for  inventors  and  innovators  who  are  able  to  work  within  a  business  model  and  platform  that  focuses  on 
intellectual property development and licensing to drive strong future growth.  

Research and Development 

Our ability to compete in the future will be substantially dependent on our ability to develop and patent key innovations that meet 
the  future  needs  of  a  dynamic  market.  To  this  end,  we  have  assembled  a  team  of  highly  skilled  engineers  and  scientists  whose 
activities  are  focused  on  continually  developing  new  innovations  within  our  chosen  technology  fields.  Using  this  foundation  of 
patented  innovations,  our  technical  teams  develop  new  solutions  that  enable  increased  performance,  greater  power  efficiency, 
increased  levels  of  security,  as  well  as  other  improvements  and  benefits.  Our  solution  design  and  development  process  is  a  multi-
disciplinary  effort  requiring  expertise  in  system  architecture,  digital  and  analog  circuit  design  and  layout,  semiconductor  process 
characteristics,  packaging,  printed  circuit  board  routing,  signal  integrity,  high-speed  testing  techniques,  optical  design,  thermal 
management, material science, cryptography, software design and development, and system integration. 

As of December 31, 2011, we had approximately 280 employees in our engineering departments, representing approximately 62% 
of  our  total  employees.  A  significant  number  of  our  scientists  and  engineers  spend  all  or  a  portion  of  their  time  on  research  and 
development. For the years ended December 31, 2011, 2010 and 2009, research and development expenses were $115.7 million, $92.7 
million  and  $67.3 million,  respectively,  including  stock-based  compensation  of  approximately  $10.5  million,  $10.2  million  and 
$9.7 million, respectively. For the year ended December 31, 2011, research and development expenses also included $15.7 million for 
retention bonuses for CRI engineers who joined Rambus in June 2011. Since innovation is critical to our future success, we expect to 
continue to invest substantial funds in research and development activities. In addition, because our license and support agreements 
often call for us to provide engineering support, a portion of our total engineering costs are allocated to the cost of contract revenue. 

Competition 

The electronics industry is intensely competitive and has been impacted by price erosion, rapid technological change, short product 
life cycles, cyclical market patterns and increasing foreign and domestic competition. We face competition from semiconductor and 
digital electronics products and systems companies, as well as other intellectual property companies, all of whom may provide their 
own technologies.  

We  believe  that  our  principal  competition  for  our  technologies  may  come  from  our  prospective  licensees,  some  of  whom  are 
evaluating and developing products based on technologies that they contend or may contend will not require a license from us. Some 
of our competitors use a system-level design approach similar to ours, including activities such as board and package design, power 

12 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
and signal integrity analysis, and thermal management. Many of these companies are larger and may have better access to financial, 
technical and other resources than we possess. 

To the extent that alternatives might provide comparable system performance at lower than or similar cost to our technologies, or 
are perceived to require the payment of no or lower royalties, or to the extent other factors influence the industry, our licensees and 
prospective  licensees  may  adopt  and  promote  alternative  technologies.  Even  to  the  extent  we  determine  that  such  alternative 
technologies  infringe  our  patents,  there  can  be  no  assurance  that  we  would  be  able  to  negotiate  agreements  that  would  result  in 
royalties being paid to us without litigation, which could be costly and the results of which would be uncertain. Litigation has been, 
and  may  continue  to  be  required  to  enforce  and  protect  our  intellectual  property  rights,  as  well  as  the  substantial  investments 
undertaken to research and develop our innovations and technologies.  

Employees 

As of December 31, 2011, we have 456 employees. None of our employees are covered by collective bargaining agreements. As 
noted above, we believe that our future success is dependent on our continued ability to identify, attract, motivate and retain qualified 
personnel.  To  date,  we  believe  that  we  have  been  successful  in  recruiting  qualified  employees  and  that  our  relationship  with  our 
employees is good. 

Patents and Intellectual Property Protection 

We maintain and support an active program to protect our intellectual property, primarily through the filing of patent applications 
and the defense of issued patents against infringement. As of December 31, 2011, we have 1,386 U.S. and foreign patents on various 
aspects of our technology, with expiration dates ranging from 2012 to 2030, and we have 1,059 pending patent applications. These 
patents and patent applications cover important inventions in semiconductor, lighting, display, security and other technologies. Some 
of the patents and pending patent applications are derived from a common parent patent application or are foreign counterpart patent 
applications. We have a program to file applications for and obtain patents in the United States and in selected foreign countries where 
we believe filing for such protection is appropriate and would further our overall business strategy and objectives. In some instances, 
obtaining  appropriate  levels  of  protection  may  involve  prosecuting  continuation  and  counterpart  patent  applications  based  on  a 
common parent application. In addition, we attempt to protect our trade secrets and other proprietary information through agreements 
with current and prospective licensees, and confidentiality agreements with employees and consultants and other security measures. 
We also rely on trademarks and trade secret laws to protect our intellectual property. 

Business Segment Data, Customers and Our Foreign Operations 

Prior  to  2010, we  operated  in  a  single  industry  segment,  the  design,  development  and  licensing of  memory  and  logic  interfaces, 
lighting  and  optoelectronics,  and  other  technologies.  In  2010,  we  reorganized,  and  as  a  result,  currently  have  two  business  groups: 
SBG which focuses on the design, development and licensing of technology that is semiconductor based, and NBG which focuses on 
the  design,  development  and  licensing  of  technologies  for  lighting,  displays,  chip  and  system  security,  anti-counterfeiting,  digital 
media  and  other  markets.  As  of  December  31,  2011,  only  SBG  was  considered  a  reportable  segment  as  it  met  the  quantitative 
thresholds for disclosure as a reportable segment. All other remaining operating segments did not meet the quantitative thresholds for 
disclosure as reportable segments. 

Information  concerning  revenue,  results  of  operations  and  revenue  by  geographic  area  is  set  forth  in  Item 6,  “Selected  Financial

Item 1A.  Risk Factors 

RISK FACTORS 

Because of the following factors, as well as other variables affecting our operating results, past financial performance may not be a 
reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. See 
also “Special Note Regarding Forward-Looking Statements” elsewhere in this report. 

Risks Associated With Our Business, Industry and Market Conditions 

If market leaders do not adopt our innovations, our results of operations could decline. 

An important part of our strategy is to penetrate our target market segments by working with leaders in those market segments. This 
strategy is designed to encourage other participants in those segments to follow such leaders in adopting our innovations. If a high 
profile industry participant adopts our innovations but fails to achieve success with its products or adopts and achieves success with a 
competing technology, our reputation and sales could be adversely affected. In addition, some industry participants have adopted, and 
others  may  in  the  future  adopt,  a  strategy  of  disparaging  our  solutions  adopted  by  their  competitors  or  a  strategy  of  otherwise 
undermining the market adoption of our solutions. 

We target market-leading companies to adopt our technologies, particularly those that develop and market high volume business 
and  consumer  products  in  semiconductors,  computing,  tablets,  handheld  devices,  mobile  applications,  gaming  and  graphics,  high 
definition televisions (“HDTVs”) and displays, general lighting, cryptography and data security. We have diversified our technologies 
through  the  establishment  of  our  NBG  operations  and  will  continue  to  seek  out  other  target  markets  in  and  related  to  computing, 
gaming and graphics, consumer electronics, mobile, general lighting, and security applications. We are subject to many risks beyond 
our control that influence whether or not a potential licensee or partner company will adopt our technologies, including, among others: 

 

 

 

 

 

 

competition faced by a company in its particular industry; 

the timely introduction and market acceptance of a company’s products; 

the engineering, sales and marketing and management capabilities of a company; 

technical challenges unrelated to our innovations faced by a company in developing its products; 

the financial and other resources of a company; and 

the degree to which our licensees promote our innovations to their customers. 

There can be no assurance that consumer products that currently use our technology will continue to do so, nor can there be any 
assurance that the consumer products that incorporate our technology will be successful in their markets in order to generate expected 
royalties. If market leaders do not successfully adopt our technologies for any of these reasons, our strategy may not be successful and, 
as a result, our results of operations could decline. 

We  have  traditionally  operated  in  the  semiconductor  industry  that  is  highly  cyclical  and  in  which  the  number  of  our  potential 
customers may be in decline as a result of industry consolidation, and we face intense competition in all of our target markets that 
may cause our results of operations to suffer. 

The  semiconductor  industry  is  intensely  competitive  and  has  been  impacted  by  price  erosion,  rapid  technological  change,  short 
product  life  cycles  and  cyclical  market  patterns.  Significant  economic  downturns  characterized  by  diminished  demand,  erosion  of 
average  selling  prices,  production  overcapacity  and  production  capacity  constraints  can  affect  the  highly  cyclical  semiconductor 
industry.  The  economic  downturn  of  the  past  several  years  and  the  threats  of  further  regional  or  worldwide  downturn  are  evident 
today. As a result, we may achieve a reduced number of licenses, tightening of customers’ operating budgets, difficulty or inability of 

16 

 
 
 
 
 
 
 
 
our customers to pay our licensing fees, extensions of the approval process for new licenses and consolidation among our customers, 
all  of  which  may  adversely  affect  the  demand  for  our  technology  and  may  cause  us  to  experience  substantial  period-to-period 
fluctuations in our operating results. 

Many of our customers operate in industries that experience significant declines as a result of the recent economic downturns. In 
particular, DRAM manufacturers, which make up many of our existing and potential licensees, have suffered material losses and other 
adverse effects to their businesses. These factors may result in industry consolidation as companies seek to reduce costs and improve 
profitability  through  business  combinations.  Consolidation  among  our  existing  DRAM  and  other  customers  may  result  in  loss  of 
revenues  under  existing  license  agreements.  Consolidation  among  companies  in  the  DRAM  and  other  industries  within  which  we 
license our technology may reduce the number of future licensees for our products and services. In either case, consolidation in the 
DRAM and other industries in which we operate may negatively impact our short-term and long-term business prospects, licensing 
revenues and results of operations.  

We face competition from semiconductor and intellectual property companies who provide their own DDR memory chip interface 
technology and solutions. In addition, most DRAM manufacturers, including our XDRTM licensees, produce versions of DRAM such 
as  SDR, DDRx, GDDRx  SDRAM  and  LPDDRx which compete  with XDRTM  chips. We believe  that  our principal  competition  for 
memory  chip  interfaces  may  come  from  our  licensees  and  prospective  licensees,  some  of  which  are  evaluating  and  developing 
products based on technologies that they contend or may contend will not require a license from us. In addition, our competitors are 
also taking a system approach similar to ours in seeking to solve the application needs of system companies. Many of these companies 
are  larger  and  may  have  better  access  to  financial,  technical  and  other  resources  than  we  possess.  Wider  applications  of  other 
developing memory technologies, including FLASH memory, may also pose competition to our licensed memory solutions.  

JEDEC has standardized what it calls extensions of DDR, known as DDR2 and DDR3. Other efforts are underway to create other 
products including those sometimes referred to as GDDR4 and GDDR5, as well as new ways to integrate products such as system-in-
package  DRAM.  To  the  extent  that  these  alternatives  might  provide  comparable  system  performance  at  lower  or  similar  cost  than 
XDRTM memory chips, or are perceived to require the payment of no or lower royalties, or to the extent other factors influence the 
industry, our licensees and prospective licensees  may adopt and promote  alternative technologies. Even to the extent we determine 
that such alternative technologies infringe our patents, there can be no assurance that we would be able to negotiate agreements that 
would result in royalties being paid to us without litigation, which could be costly and the results of which would be uncertain. 

We  also face competitive  threats  to  our  NBG operations.  The display  industry  is  intensely  competitive  and  is  impacted by  rapid 
technological  change,  shifting  government  mandates,  cyclical  market  patterns  and  increasing  foreign  and  domestic  competition.  In 
particular,  our  LDT  group  faces  competition  from  system  and  subsystem  providers  of  backlighting  and  general  lighting  solutions, 
some of which have substantial resources and operations. The security technology industry also faces robust competition. Our CRI 
group  acquired  in  2011  faces  competition  from  large  semiconductor  manufacturers  and  other  companies  that  offer  various  security 
solutions,  including  hardware  with  on-chip  security  features,  software  based  offerings  and  other  products  and  services.  Potential 
competitors  may  either  develop  their  own  competing  offerings  or  acquire  assets,  companies  or  businesses  that  provide  products  or 
services that compete with our security technologies. 

If for any of these reasons we cannot effectively compete in these primary markets, our results of operations could suffer. 

If we do not succeed in developing our new businesses, our results of operations may be adversely affected. 

The future success of NBG, which includes our LDT, CRI and MTD groups, depends on our ability to develop new or emerging 
licensing  opportunities,  diversify  our  business  into  lighting  and  displays,  data  security,  mobile  communications  and  additional 
semiconductor technologies.  

For our LDT group, we will be required to improve the visual capabilities, form factor, power efficiency and cost-effectiveness of 
backlighting  of  LCD  displays  in  products  for  computing,  gaming  and  graphics,  consumer  electronics,  mobile  and  general  lighting 
applications. We will need to keep pace with rapid changes in advanced lighting and optoelectronics technology, changing consumer 
requirements, new product introductions and evolving industry standards, any of which could render our existing technology obsolete 
if we fail to respond in a timely manner. The extent to which companies in the general lighting industry adopt solid state lighting and 
license our lighting technologies, and the timing of such adoption and licensing, if it occurs at all, is subject to many factors beyond 

17 

 
 
 
 
 
 
 
 
 
our control and is not predictable by us. We are subject to many risks beyond our control that influence whether or not a potential 
licensee or partner company will adopt and license our lighting technologies. 

For CRI, we will be required to continue to develop and provide robust data security technologies that are effective for licensees. 
Licensing of data security technologies also presents challenges in the face of intense competition. CRI will be required to continue to 
license  DPA  countermeasures  and  other  security  technologies,  and  develop  new  security  technologies  in  order  to  grow  market 
acceptance and revenue. 

Our MTD is another emerging business within NBG.  To date, our MTD group has not generated any revenue, but our intent is to 
grow MTD in order to provide innovative software and technological solutions to satisfy the anticipated requirements of developers, 
chip  suppliers  and  manufacturers  in  the  market  for  mobile  products.  If  the  development  of  our  MTD  business  does  not  occur,  our 
ability  to  achieve  success  in  this  market  may  be  limited,  and  this  may  in  turn  adversely  affect  our  potential  for  long  term  revenue 
growth.  

The development, application and licensing of new technologies in lighting display, security and mobile technology is a complex 
process  subject  to  a  number  of  uncertainties,  including  the  integration  of  our  new  businesses  into  the  rest  of  our  company.  Our 
competitors  have  significant  marketing,  workforce,  financial  and  other  resources  and  longer  operating  history  which  could  make 
acceptance  of  our  lighting,  data  security  and  mobile  technologies  more  difficult.  If  others  develop  innovative  technologies  that  are 
superior  to  ours  or  if  we  fail  to  accurately  anticipate  technology  and  market  trends,  respond  on  a  timely  basis  with  our  own  new 
enhancements and technology and achieve broad market acceptance of these enhancements and technology, our competitive position 
may be harmed and our operating results may be adversely affected.  

In order to grow, we may have to invest more resources in research and development than anticipated, which could increase our 
operating expenses and negatively impact our operating results. 

If  new  competitors,  technological  advances  by  existing  competitors,  our  entry  into  new  markets  and/or  development  of  new 
technologies  or  other  competitive  factors  require  us  to  invest  significantly  greater  resources  than  anticipated  in  our  research  and 
development efforts, our operating expenses would increase. For the years ended December 31, 2011, 2010 and 2009, research and 
development  expenses  were  $115.7  million,  $92.7  million  and  $67.3  million,  respectively,  including  stock-compensation  of 
approximately  $10.5  million,  $10.2  million  and  $9.7  million,  respectively.  For  the  year  ended  December  31,  2011,  research  and 
development expenses also included $15.7 million for retention bonuses for CRI engineers who joined Rambus in June 2011. If we are 
required to invest significantly greater resources than anticipated in research and development efforts without an increase in revenue, 
our  operating  results  could  decline.  Research  and  development  expenses  are  likely  to  fluctuate  from  time  to  time  to  the  extent  we 
make periodic incremental investments in research and development, including as a result of our investment in new technologies. In 
order  to  grow,  including  entering  new  markets  and/or  developing  new  technologies,  we  anticipate  that  we  will  continue  to  devote 
substantial resources to research and development. We expect these expenses to increase in absolute dollars in the foreseeable future 
due  to  the  increased  complexity  and  the  greater  number  of  technologies under  development  as  well  as  selectively  hiring  additional 
employees. 

Our revenue is concentrated in a few customers, and if we lose any of these customers, our revenue may decrease substantially. 

We  have  a  high  degree  of  revenue  concentration.  Our  top  five  licensees  represented  approximately  66%,  85%  and  77%  of  our 
revenues  for  the  years  ended  December  31,  2011,  2010  and  2009,  respectively.  For  the  years  ended  December  31,  2011,  revenues 
from Elpida, NVIDIA and Samsung, each accounted for 10% or more of our revenue. For the year ended December 31, 2010, revenue 
from Elpida and Samsung, each accounted for 10% or more of our total revenue. For the year ended December 31, 2009, revenue from 
AMD, Fujitsu, NEC, Panasonic and Toshiba, each accounted for 10% or more of our total revenue. As a result of our settlement with 
Samsung  in  January  2010,  Samsung  accounted  for  a  significant  portion  of  our  ongoing  licensing  revenue  since  2010  as  reflected 
above. We expect to continue to experience significant revenue concentration for the foreseeable future. 

In addition, some of our commercial agreements require us to provide certain customers with the lowest royalty rate that we provide 
to other customers for similar technologies, volumes and schedules. These clauses may limit our ability to effectively price differently 
among  our  customers,  to  respond  quickly  to  market  forces,  or  otherwise  to  compete  on  the  basis  of  price.  The  particular  licensees 
which account for revenue concentration have varied from period to period as a result of the addition of new contracts, expiration of 

18 

 
 
 
 
 
 
 
 
existing contracts, renewal of existing contracts, industry consolidation, including the combination in 2010 of NEC and Renesas, and 
the volumes and prices at which the licensees have recently sold licensed semiconductors to system companies. These variations are 
expected to continue in the foreseeable future. 

We continue to be in negotiations with licensees and prospective licensees to reach patent license agreements for DRAM devices 
and DRAM controllers. We expect that patent license royalties will continue to vary from period to period based on our success in 
renewing existing license agreements and adding new licensees, as well as the level of variation in our licensees’ reported shipment 
volumes, sales price and mix, offset in part by the proportion of licensee payments that are fixed. A number of our material license 
agreements  are  scheduled  to  expire  in  2015.  However,  we  cannot  provide  any  assurance  that  we  will  reach  agreement  on  renewal 
terms  or  that  the  royalty  rates  we  will  be  entitled  to  receive  under  the  new  agreements  will  be  as  favorable  to  us  as  our  current 
agreements.  If  we  are  unsuccessful  in  renewing  any  of  these  patent  license  agreements,  our  results  of  operations  may  decline 
significantly.  

If  we  cannot  respond  to  rapid  technological  change  in  our  target  markets  by  developing  new  innovations  in  a  timely  and  cost-
effective manner, our operating results will suffer. 

We derive most of our revenue from our chip interface technologies that we have patented. We expect that this dependence on our 
fundamental technology will continue for the foreseeable future. The semiconductor industry is characterized by rapid technological 
change, with new generations of semiconductors being introduced periodically and with ongoing improvements. The introduction or 
market  acceptance  of  competing  chip  interfaces  that  render  our  chip  interfaces  less  desirable  or  obsolete  would  have  a  rapid  and 
material adverse effect on our business, results of operations and financial condition. The announcement of new chip interfaces by us 
could  cause  licensees  or  system  companies  to  delay  or  defer  entering  into  arrangements  for  the  use  of  our  current  chip  interfaces, 
which could have a material adverse effect on our business, financial condition and results of operations.  

Our success depends on our ability to introduce and patent enhancements and new generations of our chip interface technologies 
that  keep  pace  with  other  changes  in  the  semiconductor  industry  and  which  achieve  rapid  market  acceptance.  We  must  devote 
significant  engineering  resources  to  addressing  the  need  for  higher  speed  chip  interfaces  associated  with  increases  in  the  speed  of 
microprocessors and other controllers. The technical innovations that are required for us to be successful are inherently complex and 
require long development cycles, and there can be no assurance that our development efforts will ultimately be successful. In addition, 
these innovations must be: 

 

 

 

completed before changes in the semiconductor industry render them obsolete; 

available when system companies require these innovations; and 

sufficiently compelling to cause semiconductor manufacturers to enter into licensing arrangements with us to implement 
these new technologies. 

In all of our target markets, significant technological innovations generally require a substantial investment before their commercial 
viability  can  be  determined.  There  can  be  no  assurance  that  we  have  accurately  estimated  the  amount  of  resources  required  to 
complete our innovation efforts, or that we will have, or be able to expend, sufficient resources required for the development of our 
innovations. In addition, there is market risk associated with these products for which we develop technological innovations, and there 
can  be  no  assurance  that  unit  volumes,  and  their  associated  royalties,  will  occur.  If  our  technology  fails  to  capture  or  maintain  a 
portion of the high volume target consumer market, our business results could suffer. 

Security  breaches  or  vulnerabilities  in  our  data  security  technologies  could  harm  our  reputation,  result  in  financial  losses  and 
divert resources. 

Because the techniques used by hackers to access or sabotage secure chip and other technologies change frequently and generally 
are not recognized until launched against a target, we may be unable to anticipate these techniques and may not address them in our 
CRI data security technologies. Furthermore, our data security technologies may also fail to detect or prevent security breaches due to 
a number of reasons such as the evolving nature of such threats and the continual emergence of new threats. An actual or perceived 
security  breach  of  our  licensees  or  their  end-customers,  regardless  of  whether  the  breach  is  attributable  to  the  failure  of  our  data 
19 

 
 
 
 
 
 
 
 
security technologies, could adversely affect the market's perception of our security technologies. We may not be able to correct any 
security flaws or vulnerabilities promptly, or at all. Any breaches, defects, errors or vulnerabilities in our data security technologies 
could result in: 

 

 

 

 

 

 

 

expenditure of significant financial and research and development resources in efforts to analyze, correct, eliminate or 
work-around breaches, errors or defects or to address and eliminate vulnerabilities; 

financial liability to licensees for breach of certain contract provisions; 

loss of existing or potential licensees; 

delayed or lost revenue; 

delay or failure to attain market acceptance; 

negative publicity, which will harm our reputation; and 

litigation, regulatory inquiries or investigations that may be costly and harm our reputation. 

We have in the past and may in the future make acquisitions or enter into mergers, strategic transactions or other arrangements 
that may or may not produce the expected operating and financial results. 

As part of our strategic initiatives, we currently are evaluating, and expect to continue to engage in, investments in or acquisitions 
of  companies,  products,  patents  or  technologies,  and  the  entry  into  strategic  transactions  or  other  arrangements.  We  completed  a 
number of acquisitions in 2009, 2010 and 2011, including the acquisition of CRI, our largest transaction to date. These acquisitions, 
investments,  transactions  or  arrangements  are  likely  to  range  in  size,  some  of  which  may  be  significant.  After  completing  our 
acquisitions, we may experience difficulty integrating personnel and operations, which could negatively affect our operating results. In 
addition: 

 

the key personnel of the acquired entity or business may decide not to work for us or may not perform according to our 
expectations; 

  we may experience additional legal, financial and accounting challenges and complexities in areas such as licensing, tax 

planning, cash management and financial reporting; 

  we may experience challenges with existing or prospective licensees as a result of potential conflict between pre-existing 

and historical relationships and any newly acquired engagements and agreements; 

 

our  ongoing  business,  including  our  operations,  technology  development  and  deliveries  to  our  customers,  may  be 
disrupted, and employee retention and productivity could also suffer; 

  we may not be able to recognize the financial benefits we anticipated and/or we may suffer losses, both with respect to 

our ongoing business and the acquired entity or business; 

 

 

our increasing international presence resulting from acquisitions may increase our exposure to international currency, tax 
and political risks; and 

our  lack  of  experience  with  new  products  or  technologies  in  new  markets  may  cause  us  to  fail  to  achieve  expected 
financial and strategic benefits of the acquisition. 

20 

 
 
 
 
 
 
 
 
 
 
In connection with our strategic initiatives related to future acquisitions or mergers, strategic transactions or other arrangements, we 
may incur substantial expenses regardless of whether any transactions occur. Further, the risks described above may be exacerbated as 
a result of managing multiple acquisitions simultaneously. 

In addition, we may be required to assume the liabilities of the companies or related to the businesses we acquire. The assumption 
of  such  liabilities  may  include  those  related  to  intellectual  property  infringement  or  indemnification  of  customers  of  acquired 
businesses for similar claims, which could materially and adversely affect our business. 

We may have to incur debt or issue equity securities to pay for any future acquisition, which debt or equity securities could involve 

restrictive covenants or be dilutive to our existing stockholders. 

Some of our revenue is subject to the pricing policies of our licensees over whom we have no control. 

We  have  no  control  over  our  licensees’  pricing  of  their  products  and  there  can  be  no  assurance  that  licensee  products  using  or 
containing  our  chip  interfaces  will  be  competitively  priced  or  will  sell  in  significant  volumes.  One  important  requirement  for  our 
memory chip interfaces is for any premium charged by our licensees in the price of memory and controller chips over alternatives to 
be reasonable in comparison to the perceived benefits of the chip interfaces. If the benefits of our technology do not match the price 
premium charged by our licensees, the resulting decline in sales of products incorporating our technology could harm our operating 
results.  

Our licensing cycle is lengthy and costly, and our marketing and licensing efforts may be unsuccessful. 

The process of persuading customers to adopt and license our chip interface, lighting and display, data security, mobile and other 
semiconductor technologies can be lengthy and, even if successful, there can be no assurance that our technologies will be used in a 
product  that  is  ultimately  brought  to  market,  achieves  commercial  acceptance or results  in  significant  royalties  to us. We generally 
incur significant marketing and sales expenses prior to entering into our license agreements, generating a license fee and establishing a 
royalty stream from each licensee. The length of time it takes to establish a new licensing relationship can take many months or even 
years. In addition, our ongoing intellectual property litigation and regulatory actions have and will likely continue to have an impact 
on our ability to enter into new licenses and renewals of licenses. We may incur costs in any particular period before any associated 
revenue  stream  begins,  if  at  all.  If  our  marketing  and  sales  efforts  are  very  lengthy  or  unsuccessful,  then  we  may  face  a  material 
adverse effect on our business and results of operations as a result of failure or delay to obtain royalties. 

Future  revenue  is  difficult  to  predict  for  several  reasons,  and  our  failure  to  predict  revenue  accurately  may  cause  us  to  miss 
analysts’ estimates and result in our stock price declining. 

Our lengthy and costly license negotiation cycle and our ongoing intellectual property litigation make our future revenue difficult to 
predict because we may not be successful in entering into licenses with our customers on our estimated timelines and we are reliant on 
the litigation timelines for any results or settlements. 

While some of our license agreements provide for fixed, quarterly royalty payments, many of our license agreements provide for 
volume-based royalties, and may also be subject to caps on royalties in a given period. The sales volume and prices of our licensees’ 
products in any given period can be difficult to predict. As a result, our actual results may differ substantially from analyst estimates or 
our forecasts in any given quarter. 

In addition, a portion of our revenue comes from development and support services provided to our licensees. Depending upon the 
nature  of  the  services,  a  portion  of  the  related  revenue  may  be  recognized  ratably  over  the  support  period,  or  may  be  recognized 
according  to  contract  accounting.  Contract  revenue  accounting  may  result  in  deferral  of  the  service  fees  to  the  completion  of  the 
contract, or may be recognized over the period in which services are performed on a percentage-of-completion basis. There can be no 
assurance that the product development schedule for these projects will not be changed or delayed.  

All  of  these  factors  make  it  difficult  to  predict  future  revenue  and  may  result  in  our  missing  previously  announced  earnings 

guidance or analysts’ estimates which would likely cause our stock price to decline.  

21 

 
 
 
 
 
 
 
 
 
 
A  substantial  portion  of  our  revenue  is  derived  from  sources  outside  of  the  United  States  and  this  revenue  and  our  business 
generally are subject to risks related to international operations that are often beyond our control. 

For  the  years  ended  December  31,  2011,  2010  and  2009,  revenue  received  from  our  international  customers  constituted 
approximately 67%, 93% and 83%, respectively, of our total revenue. As a result of our continued focus on international markets, we 
expect that future revenue derived from international sources will continue to represent a significant portion of our total revenue. 

To  date,  all  of  the  revenue  from  international  licensees  has  been  denominated  in  U.S.  dollars.  However,  to  the  extent  that  such 
licensees’  sales  to  systems  companies  are  not  denominated  in  U.S.  dollars,  any  royalties  which  are  based  as  a  percentage  of  the 
customer’s sales that we receive as a result of such sales could be subject to fluctuations in currency exchange rates. In addition, if the 
effective price of licensed semiconductors sold by our foreign licensees were to increase as a result of fluctuations in the exchange rate 
of the relevant currencies, demand for licensed semiconductors could fall, which in turn would reduce our royalties. We do not use 
financial instruments to hedge foreign exchange rate risk. 

We  currently  have  international  design  operations  in  India  and  business  development  operations  in  Japan,  Korea,  Taiwan  and 

Germany. Our international operations and revenue are subject to a variety of risks which are beyond our control, including: 

 

 

 

 

 

 

 

 

 

 

export controls, tariffs, import and licensing restrictions and other trade barriers; 

profits,  if  any,  earned  abroad  being  subject  to  local  tax  laws  and  not  being  repatriated  to  the  United  States  or,  if 
repatriation is possible, limited in amount; 

treatment of revenue from international sources and changes to tax codes, including being subject to foreign tax laws and 
being liable for paying withholding, income or other taxes in foreign jurisdictions, such as withholding taxes in Korea; 

foreign government regulations and changes in these regulations; 

lack of protection of our intellectual property and other contract rights by jurisdictions in which we may do business to 
the same extent as the laws of the United States; 

hiring, maintaining and managing a workforce remotely and under various legal systems;  

natural disasters, acts of war, terrorism, widespread illness or securities breaches; 

social, political and economic instability; 

geo-political issues; including changes in diplomatic and trade relationships; and 

 cultural  differences  in  the  conduct  of  business  both  with  licensees  and  in  conducting  business  in  our  international 
facilities and international sales offices. 

We  and  our  licensees  are  subject  to  many  of  the  risks  described  above with  respect  to  companies  which  are  located  in  different 
countries,  particularly  home  video  game  console,  PC  and  other  consumer  electronics  manufacturers  located  in  Asia  and  elsewhere. 
There  can  be  no  assurance  that  one  or  more  of  the  risks  associated  with  our  international  operations  will  not  result  in  a  material 
adverse effect on our business, financial condition or results of operations. 

Weak global economic conditions may adversely affect demand for the products and services of our licensees. 

Our operations and performance depend significantly on worldwide economic conditions, and the U.S. and world economies have 
experienced a prolonged period of weak economic conditions, and the threats of further regional or worldwide downturn are evident 
today. Uncertainty about global economic conditions poses a risk as consumers and businesses may postpone spending in response to 
tighter  credit,  negative  financial  news  and  declines  in  income  or  asset  values,  which  could  have  a  material  negative  effect  on  the 

22 

 
 
 
 
 
 
 
demand  for  the  products  of  our  licensees  in  the  foreseeable  future.  Other  factors  that  could  influence  demand  include  continuing 
increases in fuel and energy costs, competitive pressures, including pricing pressures, from companies that have competing products, 
changes  in  the  credit  market,  conditions  in  the  residential  real  estate  and  mortgage  markets,  consumer  confidence,  and  other 
macroeconomic  factors  affecting  consumer  spending  behavior.  If  our  licensees  experience  reduced  demand  for  their  products  as  a 
result of economic conditions or otherwise, our business and results of operations could be harmed. 

If our counterparties are unable to fulfill their financial and other obligations to us, our business and results of operations may be 
affected adversely. 

Any downturn in economic conditions or other business factors could threaten the financial health of our counterparties, including 
companies  with  whom  we  have  entered  into  licensing  arrangements,  settlement  agreements  or  that  have  been  subject  to  litigation 
judgments  that  provide  for  payments  to  us,  and  their  ability  to  fulfill  their  financial  and  other  obligations  to  us.  Such  financial 
pressures on our counterparties may eventually lead to bankruptcy proceedings or other attempts to avoid financial obligations that are 
due  to  us  under  licenses,  settlement  agreements  or  litigation  judgments.  Because  bankruptcy  courts  have  the  power  to  modify  or 
cancel contracts of the petitioner which remain subject to future performance and alter or discharge payment obligations related to pre-
petition debts, we may receive less than all of the payments that we would otherwise be entitled to receive from any such counterparty 
as  a  result  of  a  bankruptcy  proceedings.  For  example,  in  2009,  two  of  our  counterparties,  Qimonda  and  Spansion,  were  subject  to 
insolvency proceedings in their applicable jurisdictions as a result of a downturn in business which led to lower than anticipated or no 
payment to us. If we are unable to collect all of such payments owed to us, or if other of our counterparties enter into bankruptcy or 
otherwise seek to renegotiate their financial obligations to us as a result of the deterioration of their financial health, our business and 
results of operations may be affected adversely. 

If we are unable to attract and retain qualified personnel, our business and operations could suffer. 

Our  success  is  dependent  upon  our  ability  to  identify,  attract,  compensate,  motivate  and  retain  qualified  personnel,  especially 
engineers,  who  can  enhance  our  existing  technologies  and  introduce  new  technologies.  Competition  for  qualified  personnel, 
particularly  those  with  significant  industry  experience,  is  intense,  in  particular  in  the  San  Francisco  Bay  Area  where  we  are 
headquartered and in the area of Bangalore, India where we have a design center. We are also dependent upon our senior management 
personnel. The loss of the services of any of our senior management personnel, or key sales personnel in critical markets, or critical 
members of staff, or of a significant number of our engineers could be disruptive to our development efforts or business relationships 
and could cause our business and operations to suffer.  

 We  are  subject  to  government  restrictions  and  regulation,  including  on  the  sale  of  products  and  services  that  use  encryption 
technology. 

Various countries have adopted controls, license requirements and restrictions on the export, import and use of products or services 
that contain encryption technology. In addition, from time to time, governmental agencies have proposed additional requirements for 
encryption technology, such as requiring the escrow and governmental recovery of private encryption keys. Restrictions on the sale or 
distribution  of  products  or  services  containing  encryption  technology  may  impact  the  ability  of  CRI  to  license  its  data  security 
technologies to the manufacturers and providers of such products and services in certain markets or may require CRI or its licensees to 
make  changes  to  the  licensed  data  security  technology  that  is  embedded  in  such  products  to  comply  with  such  restrictions. 
Government  restrictions,  or  changes  to  the  products  or  services  of  CRI  licensees  to  comply  with  such  restrictions,  could  delay  or 
prevent  the  acceptance  and  use  of  such  licensees’  products  and  services.  In  addition,  the  United  States  and  other  countries  have 
imposed export controls that prohibit the export of encryption technology to certain countries, entities and individuals. Our failure to 
comply  with  export  and  use  regulations  concerning  encryption  technology  of  CRI  could  subject  us  to  sanctions  and  penalties, 
including  fines,  and  suspension  or  revocation  of  export  or  import  privileges.  Regulatory  initiatives  throughout  the  world  can  also 
create  new  and  unforeseen  regulatory  obligations  on  us  and  the  technology  we  develop,  particularly  for  CRI.  The  impact  of  these 
potential obligations varies based on the jurisdiction, but any such changes could impact whether we enter, maintain or expand our 
presence in a particular market or with particular potential licensees.  

Our operations are subject to risks of natural disasters, acts of war, terrorism, widespread illness or security breach at our domestic 
and international locations, any one of which could result in a business stoppage and negatively affect our operating results. 

23 

 
 
 
 
 
 
Our business operations depend on  our  ability  to  maintain  and protect our facilities,  computer  systems  and  personnel, which  are 
primarily located in the San Francisco Bay Area. The San Francisco Bay Area is in close proximity to known earthquake fault zones. 
Our  facilities  and  transportation  for  our  employees  are  susceptible  to  damage  from  earthquakes  and  other  natural  disasters  such  as 
fires, floods and similar events. Should a catastrophe disable our facilities, we do not have readily available alternative facilities from 
which  we  could  conduct  our  business,  which  stoppage  could  have  a  negative  effect  on  our  operating  results.  We  also  rely  on  our 
network  infrastructure  and  technology  systems  for  operational  support  and  business  activities,  which  are  subject  to  damage  from 
malicious code and other related vulnerabilities common to networks and computer systems, including acts of vandalism and potential 
security  breach  by  third  parties.  Acts  of  terrorism,  widespread  illness, war  and  any  event  that  causes  failures or  interruption  in our 
network infrastructure and technology systems could have a negative effect at our international and domestic facilities and could harm 
our business, financial condition, and operating results. 

Unanticipated changes in our tax rates or in the tax laws and regulations could expose us to additional income tax liabilities which 
could affect our operating results and financial condition. 

We  are  subject  to  income  taxes  in  both  the  United  States  and  various  foreign  jurisdictions.  Significant  judgment  is  required  in 
determining our worldwide provision (or benefit) for income taxes and, in the ordinary course of business, there are many transactions 
and calculations where the ultimate tax determination is uncertain. Our effective tax rate could be adversely affected by changes in the 
mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities, changes in 
tax  laws  and  regulations  as  well  as  other  factors.  Our  tax  determinations  are  regularly  subject  to  audit  by  tax  authorities  and 
developments  in  those  audits  could  adversely  affect  our  income  tax  provision.  Although  we  believe  that  our  tax  estimates  are 
reasonable, the final determination of tax audits or tax disputes may be different from what is reflected in our historical income tax 
provisions which could affect our operating results. 

Our  results  of  operations  could  vary  as  a  result  of  the  methods,  estimates  and  judgments  we  use  in  applying  our  accounting 
policies. 

The  methods,  estimates  and  judgments  we  use  in  applying  our  accounting  policies  have  a  significant  impact  on  our  results  of 
operations, including the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and 
liabilities, as described elsewhere in this report. On an ongoing basis, we evaluate our estimates, including those related to revenue 
recognition,  investments,  income  taxes,  litigation,  goodwill  and  intangibles,  and  other  contingencies.  Such  methods,  estimates  and 
judgments are, by their nature, subject to substantial risks, uncertainties and assumptions, and factors may arise over time that lead us 
to  change  our  methods,  estimates  and  judgments.  In  addition,  actual  results  may  differ  from  these  estimates  under  different 
assumptions or conditions. 

Changes  in  those  methods,  estimates  and  judgments  could  significantly  affect  our  results  of  operations.  In  particular,  the 
measurement  of  share-based  compensation  expense  requires  us  to  use  valuation  methodologies  and  a  number  of  assumptions, 
estimates  and  conclusions  regarding  matters  such  as  expected  forfeitures,  expected  volatility  of  our  share  price,  and  the  exercise 
behavior of our employees. Changes in these factors may affect both our reported results (including cost of contract revenue, research 
and  development  expenses,  marketing,  general  and  administrative  expenses  and  our  effective  tax  rate)  and  any  forward-looking 
projections  we  make  that  incorporate  projections  of  share-based  compensation  expense.  Furthermore,  there  are  no  means,  under 
applicable accounting principles, to compare and adjust our reported expense if and when we learn about additional information that 
may affect the estimates that we previously made, with the exception of changes in expected forfeitures of share-based awards. 

Factors  may  arise  that  lead  us  to  change  our  estimates  and  assumptions  with  respect  to  future  share-based  compensation 

arrangements, resulting in variability in our share-based compensation expense over time.  

Risks Related to Capitalization Matters and Corporate Governance  

The  price  of  our  common  stock  may  fluctuate  significantly,  which  may  make  it  difficult  for  holders  to  resell  their  shares  when 
desired or at attractive prices.

November 2011 verdict against us in our San Francisco antitrust proceeding, and the unpredictability of litigation results 
or settlements and the timing and amount of any litigation expenses; 

any progress, or lack of progress, real or perceived, in the development of products that incorporate our innovations and 
technology companies’ acceptance of our products, including the results of our efforts to expand into new target markets; 

our signing or not signing new licensees and the loss of strategic relationships with any licensee; 

the success of high volume consumer applications; 

the  dependence  of  our  royalties  upon  fluctuating  sales  volumes  and  prices  of  products  that  include  our  technology, 
including the seasonal shipment patterns of systems incorporating our products and semiconductor or system companies 
discontinuing major products incorporating our products; 

announcements of our technological innovations or new products by us, our licensees or our competitors; 

changes in our customers’ development schedules and levels of expenditure on research and development; 

our licensees terminating or failing to make payments under their current contracts or seeking to modify such contracts, 
whether voluntarily or as a result of financial difficulties; 

changes  in  our  strategies,  including  changes  in  our  licensing  focus  and/or  acquisitions  of  companies  with  business 
models or target markets different from our own; 

changes  in  the  economy  and  credit  market  and  their  effects  upon  demand  for  our  technology  and  the  products  of  our 
licensees; 

positive or negative reports by securities analysts as to our expected financial results and business developments; 

developments with respect to patents or proprietary rights and other events or factors; 

trading activity related to our share repurchase plans; and 

issuance of additional securities by us, including in acquisitions. 

In addition, the stock market in general, and prices for companies in our industry in particular, have experienced extreme volatility 
that  often  has  been  unrelated  to  the  operating  performance  of  such  companies.  These  broad  market  and  industry  fluctuations  may 
adversely affect the price of our common stock, regardless of our operating performance.  

Because our outstanding senior convertible notes are convertible into shares of our common stock, volatility or depressed prices of 
our common stock could have a similar effect on the trading price of our notes. In addition, the existence of the notes may encourage 
short selling in our common stock by market participants because the conversion of the notes could depress the price of our common 
stock.  

25 

 
 
 
 
 
Sales  of  substantial  amounts  of  shares  of  our  common  stock  in  the  public  market,  or  the  perception  that  those  sales  may  occur, 
could  cause  the  market  price  of  our  common  stock  to  decline.  In  addition,  lack  of  positive  performance  in  our  stock  price  may 
adversely affect our ability to retain key employees. 

We  have  been  party  to,  and  may  in  the  future  be  subject  to,  lawsuits  relating  to  securities  law  matters  which  may  result  in 
unfavorable  outcomes  and  significant  judgments,  settlements  and  legal  expenses  which  could  cause  our  business,  financial 
condition and results of operations to suffer. 

In connection with our stock option investigation, we and certain of our current and former officers and directors, as well as our 
current auditors, were subject to several stockholder derivative actions, securities fraud class actions and/or individual lawsuits filed in 
federal  court  against  us  and  certain  of  our  current  and  former  officers  and  directors.  The  complaints  generally  allege  that  the 
defendants violated the federal and state securities laws and state law claims for fraud and breach of fiduciary duty. While we have 
settled most of these actions, certain individual lawsuits continue to be adjudicated. For more information about the historic litigation 
described  above,  see  Note  16,  “Litigation  and  Asserted  Claims,”  of  Notes  Consolidated  Financial  Statements  contained  in  this 
Form 10-K.  The  amount  of  time  to  resolve  these  current  and  any  future  lawsuits  is  uncertain,  and  these  matters  could  require 
significant management and financial resources which could otherwise be devoted to the operation of our business. Although we have 
expensed or accrued for certain liabilities that we believe will result from certain of these actions, the actual costs and expenses to 
defend  and  satisfy  all  of  these  lawsuits  and  any  potential  future  litigation  may  exceed  our  current  estimated  accruals,  possibly 
significantly. Unfavorable outcomes and significant judgments, settlements and legal expenses in litigation related to our past and any 
future securities law claims could have material adverse impacts on our business, financial condition, results of operations, cash flows 
and the trading price of our common stock. 

We are leveraged financially, which could adversely affect our ability to adjust our business to respond to competitive pressures 
and to obtain sufficient funds to satisfy our future research and development needs, to protect and enforce our intellectual property 
and other needs. 

We have indebtedness. In 2009, we issued $172.5 million aggregate principal amount of our 2014 Notes. The degree to which we 

are leveraged could have important consequences, including, but not limited to, the following: 

 

 

 

our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, litigation, 
general corporate or other purposes may be limited; 

a substantial portion of our cash flows from operations in the future will be dedicated to the payment of the principal of 
our indebtedness as we are required to pay the principal amount of our 2014 Notes in cash upon conversion if specified 
conditions are met or when due; 

if  upon  any  conversion  of  our  2014  Notes  we  are  required  to  satisfy  our  conversion  obligation  with  shares  of  our 
common  stock  or  we  are  required  to  pay  a  “make-whole”  premium  with  shares  of  our  common  stock,  our  existing 
stockholders’ interest in us would be diluted; and 

  we  may  be  more  vulnerable  to  economic  downturns,  less  able  to  withstand  competitive  pressures  and  less  flexible  in 

responding to changing business and economic conditions. 

A failure to comply with the covenants and other provisions of our debt instruments could result in events of default under such 
instruments, which could permit acceleration of all of our notes. Any required repayment of our notes as a result of a fundamental 
change or other acceleration would lower our current cash on hand such that we would not have those funds available for use in our 
business. 

If we are at any time unable to generate sufficient cash flows from operations to service our indebtedness when payment is due, we 
may be required to attempt to renegotiate the terms of the instruments relating to the indebtedness, seek to refinance all or a portion of 
the indebtedness or obtain additional financing. There can be no assurance that we will be able to successfully renegotiate such terms, 
that  any  such  refinancing  would  be  possible  or  that  any  additional  financing  could  be  obtained  on  terms  that  are  favorable  or 
acceptable to us. 

26 

 
 
 
 
 
 
If securities or industry analysts change their recommendations regarding our stock adversely, our stock price and trading volume 
could decline. 

The trading market for our common stock is influenced by the research and reports that industry or securities analysts publish about 
us,  our  business  or  our  market.  If  one  or  more  of  the  analysts  who  cover  us  change  their  recommendation  regarding  our  stock 
adversely, our stock price would likely decline. If one or more of these analysts ceases coverage of our company or fails to regularly 
publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to 
decline. 

Compliance with changing regulation of corporate governance and public disclosure may result in additional expenses. 

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the historic Sarbanes-
Oxley  Act  and  recent  Dodd-Frank  Act,  and  new  Securities  and  Exchange  Commission  regulations  and  NASDAQ  rules,  have 
historically created uncertainty for companies such as ours. Any new or changed laws, regulations and standards are subject to varying 
interpretations in many cases due to their lack of specificity, and as a result, their application in practice may evolve over time as new 
guidance is provided by regulatory and governing bodies, which could result in continuing uncertainty regarding compliance matters 
and  higher  costs  necessitated  by  ongoing  revisions  to  disclosure  and  governance  practices.  Any  new  investment  of  resources  to 
comply with evolving laws, regulations and standards, may result in increased general and administrative expenses and a diversion of 
management  time  and  attention  from  revenue  generating  activities  to  compliance  activities.  If  our  efforts  to  comply  with  new  or 
changed  laws,  regulations  and  standards  differ  from  the  activities  intended  by  regulatory  or  governing  bodies  due  to  ambiguities 
related to practice, our reputation may be harmed and our business and operations would suffer.  

Our restated certificate of incorporation and bylaws, Delaware law and our outstanding convertible notes contain provisions that 
could discourage transactions resulting in a change in control, which may negatively affect the market price of our common stock. 

Our  restated  certificate  of  incorporation,  our  bylaws  and  Delaware  law  contain  provisions  that  might  enable  our  management  to 
discourage, delay or prevent a change in control. In addition, these provisions could limit the price that investors would be willing to 
pay in the future for shares of our common stock. Pursuant to such provisions: 

 

 

 

 

 

 

 

our board of directors is authorized, without prior stockholder approval, to create and issue preferred stock, commonly 
referred  to  as  “blank  check”  preferred  stock,  with  rights  senior  to  those  of  common  stock,  which  means  that  a  new 
stockholder rights plan could be implemented by our board to replace our old plan that expired in 2010; 

our board of directors is staggered into two classes, only one of which is elected at each annual meeting; 

stockholder action by written consent is prohibited; 

nominations for election to our board of directors and the submission of matters to be acted upon by stockholders at a 
meeting are subject to advance notice requirements; 

certain  provisions  in  our  bylaws  and  certificate  of  incorporation  such  as  notice  to  stockholders,  the  ability  to  call  a 
stockholder meeting, advance notice requirements and action of stockholders by written consent may only be amended 
with the approval of stockholders holding 66 2/3% of our outstanding voting stock; 

our stockholders have no authority to call special meetings of stockholders; and 

our board of directors is expressly authorized to make, alter or repeal our bylaws. 

We are also subject to Section 203 of the Delaware General Corporation Law, which provides, subject to enumerated exceptions, 
that if a person acquires 15% or more of our outstanding voting stock, the person is an “interested stockholder” and may not engage in 
any “business combination” with us for a period of three years from the time the person acquired 15% or more of our outstanding 
voting stock. 

27 

 
 
 
 
 
 
Certain provisions of our outstanding convertible notes could make it more difficult or more expensive for a third party to acquire 
us. Upon the occurrence of certain transactions constituting a fundamental change, holders of the notes will have the right, at their 
option, to require us to repurchase, at a cash repurchase price equal to 100% of the principal amount plus accrued and unpaid interest 
on the notes, all or a portion of their notes. We may also be required to issue additional shares of our common stock upon conversion 
of such notes in the event of certain fundamental changes. 

Litigation, Regulation and Business Risks Related to our Intellectual Property 

We face current and potential adverse determinations in litigation stemming from our efforts to protect and enforce our patents 
and  intellectual  property  and  make  other  claims,  which  could  broadly  impact  our  intellectual  property  rights,  distract  our 
management and cause substantial expenses and declines in our revenue and stock price. 

We  seek  to  diligently  protect  our  intellectual  property  rights. In  connection with  the  extension of our  licensing  program  to  SDR 
SDRAM-compatible and DDR SDRAM-compatible products, we became involved in litigation related to such efforts against different 
parties  in  multiple  jurisdictions.  In  each  of  these  cases,  we  have  claimed  infringement  of  certain  of  our  patents,  while  the 
manufacturers of such products have generally sought damages and a determination that the patents in suit are invalid, unenforceable 
and  not  infringed.  Among  other  things,  the  opposing  parties  have  alleged  that  certain  of  our  patents  are  unenforceable  because  we 
engaged in document spoliation, litigation misconduct and/or acted improperly during our 1991 to 1995 participation in the JEDEC 
standard setting organization (including allegations of antitrust violations and unfair competition). We have also become involved in 
litigation related to infringement of our patents related to products having certain peripheral interfaces. In addition, we did not prevail 
at jury trial in our antitrust suit against certain memory manufacturers in November 2011, which caused the market price of our stock 
to  drop  significantly,  and  we  face  appeals  and  further  proceedings  related  to  such  actions.  See  Note  16,  “Litigation  and  Asserted 
Claims,” of Notes to Consolidated Financial Statements of this Form 10-K. 

There can be no assurance that any or all of the opposing parties will not succeed, either at the trial or appellate level, with such 
claims  or  counterclaims  against  us  or  that  they  will  not  in  some  other  way  establish  broad  defenses  against  our  patents,  achieve 
conflicting results or otherwise avoid, delay paying royalties for the use of our patented technology, or obtain orders to require us to 
pay or reimburse their costs or attorneys’ fees in material amounts or post bonds to cover such amounts. Moreover, there is a risk that 
if one party prevails against us, other parties could use the adverse result to defeat or limit our claims against them; conversely, there 
can  be  no  assurance  that  if  we  prevail  against  one  party,  we  will  succeed  against  other  parties  on  similar  claims,  defenses,  or 
counterclaims. In addition, there is the risk that the pending litigations and other circumstances may cause us to accept less than what 
we now believe to be fair consideration in settlement. 

Any of these matters or any future intellectual property litigation, whether or not determined in our favor or settled by us, is costly, 
may  cause  delays  (including  delays  in  negotiating  licenses  with  other  actual  or  potential  licensees),  will  tend  to  discourage  future 
design partners, will tend to impair adoption of our existing technologies and divert the efforts and attention of our management and 
technical  personnel  from  other  business  operations.  In  addition,  we  may  be  unsuccessful  in  our  litigation  if  we  have  difficulty 
obtaining the cooperation of former employees and agents who were involved in our business during the relevant periods related to 
our litigation and are now needed to assist in cases or testify on our behalf. Furthermore, any adverse determination or other resolution 
in litigation could result in our losing certain rights beyond the rights at issue in a particular case, including, among other things: our 
being effectively barred from suing others for violating certain or all of our intellectual property rights; our patents being held invalid 
or unenforceable or not infringed; our being subjected to significant liabilities; our being required to seek licenses from third parties; 
our being prevented from licensing our patented technology; or our being required to renegotiate with current licensees on a temporary 
or permanent basis.  

Even if we are successful in our litigation, or any settlement of such litigation, there is no guarantee that the applicable opposing 
parties will be able to pay any damages awards timely or at all as a result of financial difficulties or otherwise. Delay or any or all of 
these adverse results could cause substantial expenses or declines in our revenue and stock price. 

From time to time, we are subject to proceedings by government agencies, such as our Federal Trade Commission and European 
Commission proceedings over the past several years. These proceedings may result in adverse determinations against us or in other 

28 

 
 
 
 
 
 
 
outcomes  that  could  limit  our  ability  to  enforce  or  license  our  intellectual  property,  and  could  cause  our  revenue  to  decline 
substantially. 

An adverse resolution by or with a governmental agency could result in severe limitations on our ability to protect and license our 

intellectual property, and would cause our revenue to decline substantially. 

Third parties have and may attempt to use adverse findings by a government agency to limit our ability to enforce or license our 
patents in private litigations, to challenge or otherwise act against us with respect to such government agency proceedings, such as the 
attempts by Hynix to appeal our settlement with the European Commission and to assert claims for monetary damages against us, and 
other attempts by other adverse parties to challenge our settlement. Although we have successfully defeated certain attempts to do so, 
there can be no assurance that other third parties will not be successful in the future or that additional claims or actions arising out of 
adverse findings by a government agency will not be asserted against us. 

Further, third parties have sought and may seek review and reconsideration of the patentability of inventions claimed in certain of 
our  patents  by  the  U.S.  Patent  and  Trademark  Office  (“PTO”)  and/or  the  European  Patent  Office  (the  “EPO”).  Currently,  we  are 
subject to numerous re-examination proceedings, including proceedings initiated by Hynix, Micron and NVIDIA as a defensive action 
in connection with our litigation against those companies. A number of these re-examination proceedings are being reviewed by the 
PTO’s  Board of  Patent Appeals  and Interferences  (“BPAI”).  The  BPAI  has  issued decisions  in  a  few  cases, finding  the  challenged 
claims of Rambus’s patents to be invalid. Decisions of the BPAI are subject to further PTO proceedings and appeal to the Court of 
Appeals for the Federal Circuit. A final adverse decision by the PTO or EPO could invalidate some or all of these patent claims and 
could  also  result  in  additional  adverse  consequences  affecting  other  related  U.S.  or  European  patents,  including  in  our  intellectual 
property litigation. If a sufficient number of such patents are impaired, our ability to enforce or license our intellectual property would 
be significantly weakened and this could cause our revenue to decline substantially. 

The pendency of any governmental agency acting as described above may impair our ability to enforce or license our patents or 
collect  royalties  from  existing  or  potential  licensees,  as  our  litigation  opponents  may  attempt  to  use  such  proceedings  to  delay  or 
otherwise  impair  any  pending  cases  and  our  existing  or  potential  licensees  may  await  the  final  outcome  of  any  proceedings  before 
agreeing to new licenses or pay royalties. 

Litigation or other third-party claims of intellectual property infringement could require us to expend substantial resources and 
could prevent us from developing or licensing our technology on a cost-effective basis. 

Our research and development programs are in highly competitive fields in which numerous third parties have issued patents and 
patent applications with claims closely related to the subject matter of our programs. We have also been named in the past, and may in 
the future be named, as a defendant in lawsuits claiming that our technology infringes upon the intellectual property rights of third 
parties.  As  we  develop  additional  products  and  technology,  we  may  face  claims  of  infringement  of  various  patents  and  other 
intellectual property rights by third parties. In the event of a third-party claim or a successful infringement action against us, we may 
be  required  to  pay  substantial  damages,  to  stop  developing  and  licensing  our  infringing  technology,  to  develop  non-infringing 
technology,  and  to  obtain  licenses,  which  could  result  in  our  paying  substantial  royalties  or  our  granting  of  cross  licenses  to  our 
technologies. Threatened or ongoing third-party claims of infringement actions may prevent us from pursuing additional development 
and  licensing  arrangements  for  some  period.  For  example,  we  may  discontinue  negotiations  with  certain  customers  for  additional 
licensing of our patents due to the uncertainty caused by our ongoing litigation on the terms of such licenses or of the terms of such 
licenses on our litigation. We may not be able to obtain licenses from other parties at a reasonable cost, or at all, which could cause us 
to expend substantial resources, or result in delays in, or the cancellation of, new product. 

If  we  are  unable  to  successfully  protect  our  inventions  through  the  issuance  and  enforcement  of  patents,  our  operating  results 
could be adversely affected. 

We have an active program to protect our proprietary inventions through the filing of patents. There can be no assurance, however, 

that: 

 

any current or future U.S. or foreign patent applications will be approved and not be challenged by third parties; 

29 

 
 
 
 
 
 
 
 
 

 

 

 

our issued patents will protect our intellectual property and not be challenged by third parties; 

the validity of our patents will be upheld; 

our patents will not be declared unenforceable; 

the patents of others will not have an adverse effect on our ability to do business; 

  Congress or the U.S. courts or foreign countries will not change the nature or scope of rights afforded patents or patent 

owners or alter in an adverse way the process for seeking or enforcing patents; 

 

 

 

 

changes in law will not be implemented, or changes in interpretation of such laws will occur, that will affect our ability 
to  protect  and  enforce  our  patents  and  other  intellectual  property,  including  as  a  result  of  the  2011  passage  of  the 
America Invents Act of 2011 (which codifies several significant changes to the U.S. patent laws and will remain subject 
to certain rule-making and interpretation, including changing from a “first to invent” to a “first inventor to file” system, 
limiting where a patentee may file a patent suit, requiring the apportionment of patent damages, replacing interference 
proceedings  with  derivation  actions,  and  creating  a  post-grant  opposition  process  to  challenge  patents  after  they  have 
issued); 

new legal theories and strategies utilized by our competitors will not be successful; 

others  will  not  independently  develop  similar  or  competing  chip  interfaces  or  design  around  any  patents  that  may  be 
issued to us; or 

factors such as difficulty in obtaining cooperation from inventors, pre-existing challenges or litigation, or license or other 
contract issues will not present additional challenges in securing protection with respect to patents and other intellectual 
property that we acquire. 

If any of the above were to occur, our operating results could be adversely affected. 

In  addition,  our  patents  will  continue  to  expire  according  to  their  terms,  with  expiration  dates  ranging  from  2012  to  2030.  Our 
failure to continuously develop or acquire successful innovations and obtain patents on those innovations could significantly harm our 
business, financial condition, results of operations, or cash flows. 

Our inability to protect and own the intellectual property we create would cause our business to suffer. 

We rely primarily on a combination of license, development and nondisclosure agreements, trademark, trade secret and copyright 
law and contractual provisions to protect our non-patentable intellectual property rights. If we fail to protect these intellectual property 
rights, our licensees and others may seek to use our technology without the payment of license fees and royalties, which could weaken 
our  competitive  position,  reduce  our  operating  results  and  increase  the  likelihood  of  costly  litigation.  The  growth  of  our  business 
depends in large part on the use of our intellectual property in the products of third party manufacturers, and our ability to enforce 
intellectual  property  rights  against  them  to  obtain  appropriate  compensation.  In  addition,  effective  trade  secret  protection  may  be 
unavailable or limited in certain foreign countries. Although we intend to protect our rights vigorously, if we fail to do so, our business 
will suffer. 

We  rely  upon  the  accuracy  of  our  licensees’  recordkeeping,  and  any  inaccuracies  or  payment  disputes  for  amounts  owed  to  us 
under our licensing agreements may harm our results of operations. 

Many  of  our  license  agreements  require  our  licensees  to  document  the  manufacture  and  sale  of  products  that  incorporate  our 
technology and report this data to us on a quarterly basis. While licenses with such terms give us the right to audit books and records 
of  our  licensees  to  verify  this  information,  audits  rarely  are  undertaken  because  they  can  be  expensive,  time  consuming,  and 
potentially  detrimental  to  our  ongoing  business  relationship  with  our  licensees.  Therefore,  we  typically  rely  on  the  accuracy  of  the 

30 

 
 
 
 
 
 
reports from licensees without independently verifying the information in them. Our failure to audit our licensees’ books and records 
may  result  in  our  receiving  more  or  less  royalty  revenue  than  we  are  entitled  to  under  the  terms  of  our  license  agreements.  If  we 
conduct  royalty  audits  in  the  future,  such  audits  may  trigger  disagreements  over  contract  terms  with  our  licensees  and  such 
disagreements  could  hamper  customer  relations,  divert  the  efforts  and  attention  of  our  management  from  normal  operations  and 
impact our business operations and financial condition. 

Any  dispute  regarding  our  intellectual  property  may  require  us  to  indemnify  certain  licensees,  the  cost  of  which  could  severely 
hamper our business operations and financial condition. 

In any potential dispute involving our patents or other intellectual property, our licensees could also become the target of litigation. 
While we generally do not indemnify our licensees, some of our license agreements provide limited indemnities, and some require us 
to provide technical support and information to a licensee that is involved in litigation involving use of our technology. In addition, we 
may agree to indemnify others in the future. Any of these indemnification and support obligations could result in substantial expenses. 
In addition to the time and expense required for us to indemnify or supply such support to our licensees, a licensee’s development, 
marketing and sales of licensed semiconductors, lighting and display, mobile communications and data security technologies could be 
severely disrupted or shut down as a result of litigation, which in turn could severely hamper our business operations and financial 
condition as a result of lower or no royalty payments.

Information regarding our securities authorized for issuance under equity compensation plans will be included in Item 12, “Security 

Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters,” of this report on Form 10-K. 

As of January 31, 2012, there were 695 holders of record of our Common Stock. Since many of the shares of our Common Stock 
are  held  by  brokers  and  other  institutions  on  behalf  of  stockholders,  we  are  unable  to  estimate  the  total  number  of  beneficial 
stockholders represented by these record holders.  

We have never paid or declared any cash dividends on our Common Stock or other securities.  

Contingently Redeemable Common Stock 

On  January  19,  2010,  pursuant  to  the  terms  of  the  Stock  Purchase  Agreement,  Samsung  purchased  for  cash  from  us  9.6  million 
shares of our common stock (the “Shares”) with certain restrictions and put rights. The issuance of the Shares by us to Samsung was 
made through a private transaction. The Stock Purchase Agreement provided Samsung a one-time put right, beginning 18 months after 
the date of the Stock Purchase Agreement and extending to 19 months after the date of the Stock Purchase Agreement, to put back to 
us up to 4.8 million of the Shares at the original issue price of $20.885 per share (for an aggregate purchase price of up to $100.0 
million).  The  4.8  million  shares  were  recorded  as  contingently  redeemable  common  stock  on  the  consolidated  balance  sheet  as  of 
December 31, 2010. 

The Stock Purchase Agreement prohibited the transfer of the Shares by Samsung for 18 months after the date of the Stock Purchase 
Agreement,  subject  to  certain  exceptions.  After  expiration  of  the  transfer  restriction  period  on  July  18,  2011,  the  Stock  Purchase 
Agreement provided that Samsung could transfer a limited number of shares on a daily basis, provide us with a right of first offer for 
proposed transfers above certain daily limits, and, if no sale occurs to us under the right of first offer, allowed Samsung to transfer the 
Shares. Under the Stock Purchase Agreement, we also agreed that after the transfer restriction period, Samsung would have certain 
rights to register the Shares for sale under the securities laws of the United States, subject to customary terms and conditions. 

On  July  20,  2011,  we  received  notice  from  Samsung  exercising  their  option  to  put  back  to  us  approximately  4.8  million  of  the 
Shares for cash of $100.0 million. In August 2011, we paid $100.0 million to Samsung in exchange for the 4.8 million shares, which 
were retired. The difference between the amount recorded as contingently redeemable common stock and the cash paid was recorded 
as additional paid-in capital in our consolidated balance sheet. 

See Note 4, “Settlement Agreement with Samsung,” of Notes to Consolidated Financial Statements of this Form 10-K for further 

discussion. 

Share Repurchase Program 

In October 2001, our Board of Directors (the “Board”) approved a share repurchase program of our Common Stock, principally to 
reduce the dilutive effect of employee stock options. Under this program, the Board approved the authorization to repurchase up to 
19.0 million shares of our outstanding Common Stock over an undefined period of time. On February 25, 2010, the Board approved a 
new  share  repurchase  program  authorizing  the  repurchase  of  up  to  an  additional  12.5  million  shares. Share  repurchases  under  the 
program  may  be  made  through open  market,  established plan  or  privately  negotiated  transactions  in accordance  with  all  applicable 
securities  laws,  rules,  and  regulations. There  is  no  expiration  date  applicable  to  the  program. The  new  share  repurchase  program 
replaces the program authorized in October 2001. 

On  August  19,  2010,  we  entered  into  a  share  repurchase  agreement  (the  “Share  Repurchase  Agreement”)  with  J.P.  Morgan 
Securities Inc., as agent for JPMorgan Chase Bank, National Association, London Branch (“JP Morgan”) to repurchase approximately 
$90.0 million of our Common Stock, as part of our share repurchase program. Under the Share Repurchase Agreement, we pre-paid to 
JP  Morgan  the  $90.0  million  purchase  price  in  the  third  quarter  of  2010  for  the  Common  Stock  and  JP  Morgan  delivered  to  us 
approximately  4.8  million  shares  of  Common  Stock  at  an  average  price  of  $18.88  at  the  completion  of  the  Share  Repurchase 
Agreement in December 2010. 

For  the  year  ended  December  31,  2011,  we  did  not  repurchase  any  shares  of  our  Common  Stock  under  our  share  repurchase 
program.  For  the  year  ended December  31, 2010, we  repurchased  approximately  9.5  million  shares of our  Common  Stock with  an 

34 

 
 
 
 
 
 
 
 
 
 
 
 
  
aggregate price of approximately $195.1 million, including the price paid pursuant to the Share Repurchase Agreement. For the year 
ended  December  31,  2009,  we  did  not  repurchase  any  shares  of  our  Common  Stock  under  our  share  repurchase  program.  As  of 
December  31,  2011,  we  had  repurchased  a  cumulative  total  of  approximately  26.3 million  shares  of  our  Common  Stock  with  an 
aggregate price of approximately $428.9 million since the commencement of the program in 2001. As of December 31, 2011, there 
remained an outstanding authorization to repurchase approximately 5.2 million shares of our outstanding Common Stock. 

We record stock repurchases as a reduction to stockholders’ equity. We record a portion of the purchase price of the repurchased 
shares as an increase to accumulated deficit when the price of the shares repurchased exceeds the average original proceeds per share 
received from the issuance of Common Stock. During the year ended December 31, 2011, we did not repurchase any Common Stock. 
During the year ended December 31, 2010, the cumulative price of the shares repurchased exceeded the proceeds received from the 
issuance of the same number of shares. The excess of $163.6 million was recorded as an increase to accumulated deficit for the year 
ended December 31, 2010. During the year ended December 31, 2009, we did not repurchase any Common Stock.

Business Overview 

We  are  a  premier  intellectual  property  and  technology  licensing  company  focusing  on  the  creation,  design,  development  and 
licensing  of  patented  innovations,  technologies  and  architectures  that  are  foundational  to  nearly  all  digital  electronics  products  and 
systems. Our mission is to continuously enrich the end-user experience of electronic systems through groundbreaking innovations and 
technologies  designed  to  improve  the  performance,  power  efficiency,  time-to-market  and  cost-effectiveness  of  the  products, 
components  and  systems  offered  by  market-leading  companies  in  semiconductors,  computing,  tablets,  handheld  devices,  mobile 
applications,  gaming  and  graphics,  high  definition  televisions  and  displays,  general  lighting,  cryptography  and  data  security.  Our 
inventors  and  engineering  teams  focus  on  creating  innovations  designed  to  address  the  most  challenging  demands  of  each  target 
market  and  industry.  We  believe  we  have  established  an  unparalleled  licensing  platform  and  business  model  that  will  continue  to 
foster the development of new foundational technologies. By continuing to build upon this platform, our goal is to create additional 
licensing opportunities, and thereby perpetuate strong company operating performance and long-term stockholder value.  

While we have historically focused our efforts in the development of technologies for electronics memory and chip interfaces, we 
have  been  expanding  our  portfolio  of  inventions  and  solutions  to  address  additional  markets  in  lighting,  displays,  chip  and  system 
security, digital media, as well as new areas within the semiconductor industry, such as imaging and non-volatile memory. We intend 
to continue our growth into new technology fields, consistent with our mission to create great value through our innovations and to 
make those technologies available through our licensing business model. Key to our efforts, both in our current businesses and in any 
new  area  of  diversification,  will  be  hiring  and  retaining  world-class  inventors,  scientists  and  engineers  to  lead  the  development  of 
inventions  and  technology  solutions  for  these  fields  of  focus,  and  the  management  and  business  support  personnel  necessary  to 
execute our plans and strategies. 

Prior  to  2010, we  operated  in  a  single  industry  segment,  the  design,  development  and  licensing of  memory  and  logic  interfaces, 
lighting  and  optoelectronics,  and  other  technologies.  In  2010,  we  reorganized,  and  as  a  result,  currently  have  two  business  groups: 
SBG which focuses on the design, development and licensing of technology that is semiconductor based, and NBG which focuses on 
the  design,  development  and  licensing  of  technologies  for  lighting,  displays,  chip  and  system  security,  anti-counterfeiting,  digital 
media  and  other  markets.  As  of  December  31,  2011,  only  SBG  was  considered  a  reportable  segment  as  it  met  the  quantitative 
thresholds  for  disclosure  as  a  reportable  segment.  As  such,  segment  information  is  not  separately  discussed  below.  For  additional 
information  concerning  segment  reporting,  see  Note  14,  “Business  Segments  and  Major  Customers,”  of  Notes  to  Consolidated 
Financial Statements of this Form 10-K. 

The key elements of our strategy are as follows:  

Innovate:  Develop and patent our innovative technology to provide fundamental competitive advantage when incorporated into 

semiconductors, and digital electronics products and systems. 

36 

 
 
 
 
 
 
 
 
 
 
 
 
 
Drive Adoption:  Communicate the advantages of our patented innovations and technologies to the industry and encourage its 

adoption through demonstrations and incorporation in the products of select customers. 

Monetize:  License  our  patented  inventions  and  technology  solutions  to  customers  for  use  in  their  semiconductor  and  system 

products. 

As  of  December  31,  2011,  our  semiconductor,  lighting,  display,  security  and  other  technologies  are  covered  by  1,386  U.S.  and 
foreign  patents.  Additionally,  we  have  1,059  patent  applications  pending.  Some  of  the  patents  and  pending  patent  applications  are 
derived  from  a  common  parent  patent  application  or  are  foreign  counterpart  patent  applications.  We  have  a  program  to  file 
applications for and obtain patents in the United States and in selected foreign countries where we believe filing for such protection is 
appropriate  and  would  further  our  overall  business  strategy  and  objectives.  In  some  instances,  obtaining  appropriate  levels  of 
protection  may  involve  prosecuting  continuation  and  counterpart  patent  applications  based  on  a  common  parent  application.  We 
believe  that  our  patented  innovations  provide  our  customers  means  to  achieve  improved  performance,  lower  risk,  greater  cost-
effectiveness and other benefits in their products and services. 

Our  patented  inventions  and  technology  solutions  are  offered  to  our  customers  through  either  a  patent  license  or  a  solutions 
license.  Our  revenues  are  primarily  derived  from  patent  licenses,  through  which  we  provide  our  customers  a  license  to  use  some 
specified portion of our broad portfolio of patented inventions. The patent license essentially provides our customers with a defined 
right to use our patented innovations in the customer’s own digital electronics products, systems or services, as applicable. The patent 
licenses  may  also  define  the  specific  field  of  use  where  our  customers  may  use  or  employ  our  inventions  in  their  products.  Patent 
license agreements are structured with fixed, variable or a hybrid of fixed and variable royalty payments over certain defined periods. 

We also offer our customers solutions licenses to support the implementation and adoption of our technology in their products or 
services.  Our  solutions  license  offerings  include  a  range  of  solutions  developed  by  Rambus,  which  include  “leadership”  solutions 
(which  are  Rambus-proprietary  solutions  widely  licensed  to  our  customers)  and  industry-standard  solutions  that  we  provide  to  our 
customers under license for incorporation into our customers’ digital electronics products and systems. We offer a range of services as 
part  of  our  solutions  licenses  which  can  include  know-how  and  technology  transfer,  product  design  and  development,  system 
integration,  supply  chain  consulting  and  other  services.  These  solutions  license  agreements  may  have  both  a  fixed  price  (non-
recurring) component and ongoing royalties. Further, under solutions licenses, our customers typically receive licenses to our patents 
necessary  to  implement  these  solutions  in their  products  with  specific  rights  and  restrictions  to  the applicable patents  elaborated in 
their individual contracts with us. 

Royalties represent a substantial majority of our total revenue. We derive the majority of our royalty revenue by licensing our broad 
portfolio of patents for chip interfaces to our customers. These licenses may cover part or all of our patent portfolio across our breadth 
of  technologies.  Leading  semiconductor  and  system  companies  such  as  AMD,  Broadcom,  Elpida,  Freescale,  Fujitsu,  GE,  Intel, 
Panasonic, Renesas, Samsung and Toshiba have licensed our patents for use in their own products. 

We  also  derive  additional  revenue  by  licensing  a  range  of  technology  solutions  including  our  leadership  and  industry-standard 
solutions  to  customers  for  use  in  their  digital  electronics  products  and  systems.  Our  customers  include  leading  companies  such  as 
Elpida, GE, IBM,  Panasonic,  Samsung,  Sony  and Toshiba. Due  to  the  often  complex  nature of  implementing  our  technologies,  we 
provide engineering services under certain of these licenses to help our customers successfully integrate our technology solutions into 
their semiconductor and system products. Licensees may also receive, in addition to their solutions license agreements, patent licenses 
as necessary to implement the technology in their products with specific rights and restrictions to the applicable patents elaborated in 
their individual contracts. 

The remainder of our revenue is contract services revenue which includes license fees and engineering services fees. The timing 
and amounts invoiced to customers can vary significantly depending on specific contract terms and can therefore have a significant 
impact on deferred revenue or account receivables in any given period. 

We  intend  to  continue  making  significant  expenditures  associated  with  engineering,  marketing,  general  and  administration 
including litigation expenses, and expect that these costs and expenses will continue to be a significant percentage of revenue in future 
periods. Whether such expenses increase or decrease as a percentage of revenue will be substantially dependent upon the rate at which 
our revenue or expenses change.

Executive Summary 

During 2011, we renewed patent license agreements with Panasonic and Toshiba as well as signed a patent license agreement with 
Freescale and Broadcom. As a result of the patent license agreement with both Broadcom and Freescale, we settled all outstanding 
claims with them, including resolution of past use of our patented innovations. On June 3, 2011, we completed our largest acquisition 
to  date,  CRI,  a  security  research  and  development  and  licensing  company.  We  acquired  all  of  the  issued  and  outstanding  common 
shares of CRI in exchange for cash of $168.8 million and Common Stock with a value of approximately $88.4 million at closing. This 
acquisition  expands  the  breadth  of  Rambus’  technologies  available  for  licensing  with  complementary  technologies  from  CRI  that 
include  patented  innovations  and  solutions  for  content  protection,  network  security  and  anti-counterfeiting.  In  connection  with  the 
acquisition of CRI, we are obligated to pay retention bonuses to certain CRI employees and contractors, subject to certain eligibility 
and acceleration provisions, including continued employment with us, in three equal amounts of approximately $16.7 million, with the 
first payment paid in cash and the remaining payments in cash or stock at our election, on June 3, 2012, 2013 and 2014, respectively. 
The  total  retention  bonus  commitment  is  $50.0  million  and  may  be  forfeited  in  part  or  whole  by  the  covered  employees  and 
contractors upon voluntary departure from employment or discontinuation of services. Any amounts forfeited will be paid by us to a 
designated  charity.  See  Note  18,  “Acquisition,”  of  Notes  to  Consolidated  Financial  Statements  of  this  Form 10-K  for  further 
discussion. Additionally, we signed a patent license agreement in 2011 with a major smartphone and tablet manufacturer for the use of 
CRI’s Differential Power Analysis (“DPA”) countermeasures patents. 

Research and development continues to play a key role in our efforts to maintain product innovations. Our engineering expenses for 
the year ended December 31, 2011 increased $40.1 million as compared to 2010 primarily due to increased headcount related costs of 
$6.9  million  from  additional  employees  (including  employees  from  our  CRI  acquisition)  to  support  our  development  efforts,  the 
accrual  of  the  CRI  retention  bonuses  of  $15.7  million  and  increased  amortization  expenses  related  to  intangible  assets  acquired  of 
$13.6 million. Our lower revenue combined with the increase in engineering expenses has caused engineering expenses to increase as 
a  percentage  of  revenue.  Marketing,  general  and  administrative  expenses  in  aggregate  increased  $44.7  million  for  the  year  ended 
December  31,  2011  as  compared  to  2010  primarily  due  to  litigation  expenses  being  higher  by  $38.3  million.  Our  lower  revenue 
combined  with  the  increase  in  marketing,  general  and  administrative  expenses,  has  caused  marketing,  general  and  administrative 
expenses to increase as a percentage of revenue. Additionally, for the year ended December 31, 2011, we incurred costs of restatement 
and related legal activities of $16.2 million primarily due to the $10.9 million settlement in the matter captioned Stuart J. Steele, et al. 
v. Rambus Inc., et al., related to the previous stock option investigation, settling the claims against us and the individual defendants as 
well as the associated litigation expense. 

Trends 

There are a number of trends that may or will have a material impact on us in the future, including but not limited to, the evolution 
of memory technology, adoption of LEDs in general lighting, and global economic conditions with the resulting impact on sales of 
consumer electronic systems.  

We have a high degree of revenue concentration, with our top five licensees representing approximately and 66%, 85% and 77% of 
our revenue for the years ended December 31, 2011, 2010 and 2009, respectively. As a result of our settlement with Samsung in 2010, 
Samsung is expected to account for a significant portion of our ongoing licensing revenue. For the year ended December 31, 2011, 
revenue from Elpida, NVIDIA and Samsung each accounted for 10% or more of our total revenue. For the year ended December 31, 
2010,  revenue  from  Elpida  and  Samsung  each  accounted  for  10%  or  more  of  our  total  revenue.  For  the  year  ended  December 31, 
2009, revenue from AMD, Fujitsu, NEC, Panasonic, and Toshiba, each accounted for 10% or more of our total revenue. We expect to 
continue to experience significant revenue concentration for the foreseeable future. 

The particular licensees which account for revenue concentration have varied from period to period as a result of the addition of 
new contracts, expiration of existing contracts, renewals of existing contracts, industry consolidation and the volumes and prices at 
which the licensees have recently sold licensed semiconductors to system companies. These variations are expected to continue in the 
foreseeable future. 

38 

 
 
 
 
 
 
 
 
 
 
The semiconductor industry is intensely competitive and highly cyclical. Our visibility with respect to future sales is very limited at 
this time. To the extent that macroeconomic fluctuations negatively affect our principal licensees, the demand for our technology may 
be significantly and adversely impacted and we may experience substantial period-to-period fluctuations in our operating results.  

The royalties we receive from our semiconductor business are partly a function of the adoption of our chip interfaces by system 
companies.  Many  system  companies  purchase  semiconductors  containing  our  chip  interfaces  from  our  licensees  and  do  not  have  a 
direct contractual relationship with us. Our licensees generally do not provide us with details as to the identity or volume of licensed 
semiconductors purchased by particular system companies. As a result, we face difficulty in analyzing the extent to which our future 
revenue will be dependent upon particular system companies. System companies face intense competitive pressure in their markets, 
which are characterized by extreme volatility, frequent new product introductions and rapidly shifting consumer preferences.  

The display industry is also intensely competitive and highly cyclical. Since LED backlighting solutions are increasingly pervasive 
in LCD for computers, smartphones, tablets, game systems, high definition televisions and any user interface incorporating an active 
display, the continued move to higher resolution displays across these products requires more LEDs per system. The increased usage 
of  LEDs  is  thereby  creating  a  need  for  increased  power  efficiency  since  the  LED  backlight  is  the  primary  source  of  power 
consumption in many consumer electronics products, including smartphones. Our LDT group has numerous patents in edge lit LED 
lightguide technology. Our plans are to license our technology to key companies that use LED edge lit display products.  

The highly fragmented general lighting industry is undergoing a fundamental shift from incandescent technology to cold cathode 
fluorescent lights and LED driven technology by the need to reduce energy consumption and to comply with government mandates. 
LED lighting typically saves energy costs as compared to existing installed lighting. Our LDT group has numerous patents in LED 
edge lit lightguide technology which can be applied in the design of next generation LED lighting products. Our goal is to be a major 
player in the general lighting industry with our technology and have established a technology center in Brecksville, Ohio.  

Our revenue from companies headquartered outside of the United States accounted for approximately 67%, 93% and 83% of our 
total revenue for the years ended December 31, 2011, 2010 and 2009, respectively. We expect that revenue derived from international 
licensees  will  continue  to  represent  a  significant  portion  of  our  total  revenue  in  the  future.  To  date,  all  of  the  revenue  from 
international licensees have been denominated in U.S. dollars. However, to the extent that such licensees’ sales to their customers are 
not denominated  in  U.S. dollars,  any  royalties  that  we  receive  as  a  result  of  such  sales  could  be  subject  to  fluctuations  in  currency 
exchange rates. In addition, if the effective price of licensed semiconductors sold by our foreign licensees were to increase as a result 
of fluctuations in the exchange rate of the relevant currencies, demand for licensed semiconductors could fall, which in turn would 
reduce our royalties. We do not use financial instruments to hedge foreign exchange rate risk. 

For additional information concerning international revenue, see Note 14, “Business Segments and Major Customers,” of Notes to 

Consolidated Financial Statements of this Form 10-K. 

Engineering costs in the aggregate and as a percentage of net sales increased in the year ended December 31, 2011 as compared to 
the prior year. In the near term, we expect engineering costs to be higher than in 2011 as we intend to continue to make investments in 
the infrastructure and technologies required to maintain our product innovations in semiconductor and lighting technologies and newly 
acquired businesses, such as CRI.  

Marketing,  general  and  administrative  expenses  in  the  aggregate  and  as  a  percentage  of  net  sales  increased  in  the  year  ended 
December 31, 2011 as compared to the prior year. Historically, we have been involved in litigation stemming from the unlicensed use 
of our inventions. Our litigation expenses have been high and difficult to predict and future litigation expenses could be significant, 
volatile and difficult to predict. If we are successful in the litigation and/or related licensing, our revenue could be substantially higher 
in  the  future;  if  we  are  unsuccessful,  our  revenue  may  not  grow  or  may  decrease.  Furthermore,  our  success  in  litigation  matters 
pending before courts and regulatory bodies that relate to our intellectual property rights have impacted and will likely continue to 
impact our ability and the terms upon which we are able to negotiate new or renegotiate existing licenses for our technology. We will 
continue to pursue litigation against those companies that have infringed our patented technologies, which in turn will keep litigation 
expenses significant until such litigation is resolved.  

As we continue to pursue litigation and invest in research and development projects and if we experience lower revenue from our 

licensees in the future, our cash from operations will be negatively affected.

Royalty Revenue 

Patent Licenses 

Our  patent  royalties  decreased  approximately  $20.8 million  to  $267.6 million  for  the  year  ended  December 31,  2011  from 
$288.4 million for the same period in 2010. The decrease was primarily due to the one-time recognition of royalty revenue from the 
settlement  agreement  signed  with  Samsung  in  2010  which  was  partially  offset  by  the  revenue  recognized  from  one-time  and/or 
ongoing licensing agreements with NVIDIA, Broadcom, Freescale and a major smartphone and tablet manufacturer in 2011. 

In  2011,  we  renewed  patent  license  agreements  with  Toshiba  and  Panasonic  and  signed  new  license  agreements  with  Freescale, 
Broadcom and a major smartphone and tablet  manufacturer. Some of these new agreements in 2011 had one-time catch up royalty 
payments,  and  in  the  aggregate,  for  2011,  these  one-time  payments  for  past  dues  amounted  to  $44.7  million  dollars.  In  2010,  we 
renewed patent license agreements with AMD, Elpida and Renesas. In 2010, we also signed patent license agreement with NVIDIA 
and  settlement  agreement  with  Samsung.  The  one-time  royalty  payments  from  these  new  agreements  in  2010  amounted  to  $136.4 
million. Excluding  the non-recurring portion from  the  patent royalties,  the recurring patent  royalties  increased  approximately  $70.9 
million to $222.9 million for the year ended December 31, 2011 from $152.0 million for the same period in 2010. The increase was

primarily  due  to  the  complete  allocation  of  Samsung’s  quarterly  license  payment  to  revenue  since  the  second  quarter  of  2011  and 
revenue recognized from agreements signed since the third quarter of 2010.  

Our  patent  royalties  increased  approximately  $209.1 million  to  $288.4 million  for  the  year  ended  December 31,  2010  from 
$79.3 million for the same period in 2009. The increase was primarily due to the revenue recognized from the agreements signed with 
Samsung and Elpida during 2010. 

We are in negotiations with prospective licensees as well as existing licensees regarding renewals. We expect patent royalties will 
continue to vary from period to period based on our success in renewing existing license agreements and adding new licensees, as well 
as the level of variation in our licensees’ reported shipment volumes, sales price and mix, offset in part by the proportion of licensee 
payments that are fixed or hybrid in nature. 

Solutions Licenses 

Royalties  from  solutions  licenses  decreased  approximately  $0.4  million  to  $31.4  million  for  the  year  ended  December  31,  2011 
from $31.8 million for the same period in 2010. The decrease was primarily due to lower royalties reported from decreased shipments 
related to DDR2 technologies. 

Royalties from solutions licenses increased approximately $3.1 million to $31.8 million for the year ended December 31, 2010 from 
$28.7  million  for  the  same  period  in  2009.  The  increase  was  primarily  due  to  higher  royalties  reported  from  increased  shipments 
related  to  DDR2  technologies  and  higher  royalties  from  XDRTM  DRAM  associated  with  increased  shipments  of  the  Sony 
PlayStation®3 product, partially offset by lower royalties from RDRAMTM controllers in the first half of 2010 due to a one-time catch-
up royalty payment for the Sony PlayStation®2 product in the second quarter of 2009. 

In the future, we expect solutions royalties will continue to vary from period to period based on our licensees’ shipment volumes, 

sales prices, and product mix.  

Contract Revenue 

Contract revenue increased approximately $10.2 million to $13.4 million for the year ended December 31, 2011 from $3.2 million 

for the year ended December 31, 2010. The increase was primarily due to new technology development contracts. 

Contract revenue decreased approximately $1.8 million to $3.2 million for the year ended December 31, 2010 from $5.0 million for 
the year ended December 31, 2009. The decrease was primarily due to fewer new technology development contracts and decrease in 
work performed on existing technology development contracts. 

We believe that contract revenue recognized will continue to fluctuate over time based on our ongoing contractual requirements, the 
amount  of  work  performed,  the  timing  of  completing  engineering  deliverables,  and  by  changes  to  work  required,  as  well  as  new 
technology development contracts booked in the future.

Engineering  costs  are  allocated  between  cost  of  revenue  and  research  and  development  expenses.  Cost  of  revenue  reflects  the 
portion of the total engineering costs which are specifically devoted to individual licensee development and support services as well as 
amortization expense related to various acquired intellectual property for patent licensing. The balance of engineering costs, incurred 
for  the  development  of  applicable  technologies,  is  charged  to  research  and  development.  In  a  given  period,  the  allocation  of 
engineering  costs  between  these  two  components  is  a  function  of  the  timing  of  the  development  and  implementation  schedules  of 
individual licensee contracts. 

For the year ended December 31, 2011 as compared to the same period in 2010, total engineering costs increased 40.3% primarily 
due to increased headcount related costs of $6.9 million from additional employees (including employees from the CRI acquisition) to 
support our development efforts, increased amortization expense related to intangible assets acquired of $13.6 million as well as the 
accrual of the CRI retention bonuses of $15.7 million and higher prototyping costs of $3.1 million, offset by the $2.8 million decrease 
in funding for our 2011 corporate incentive plan (“CIP”) which is lower than our 2010 CIP.  

For the year ended December 31, 2010 as compared to the same period in 2009, total engineering costs increased 34.4% primarily 
due to the increase in headcount from our LDT group and the funding for our 2010 CIP, which included the employee bonus related to 
the Samsung settlement, increase in patent research costs and additional amortization expense related to intangible assets acquired in a 
business combination in 2009.  

In the near term, we intend to continue to make investments in the infrastructure and technologies required to maintain our product 

innovation in semiconductor, lighting, security and other technologies.

Marketing,  general  and  administrative  expenses  include  expenses  and  costs  associated  with  trade  shows,  public  relations, 
advertising,  litigation,  general  legal,  insurance  and  other  marketing  and  administrative  efforts.  Litigation  expenses  are  a  significant 
portion of our marketing, general and administrative expenses and can vary significantly from quarter to quarter. Consistent with our 
business model, our licensing and marketing activities aim to develop or strengthen relationships with potential and current licensees. 
In addition, we work with current licensees through marketing, sales and technical efforts to drive adoption of their products that use 
our innovations and solutions, by system companies. Due to the long business development cycles we face and the semi-fixed nature 
of marketing, general and administrative expenses in a given period, these expenses generally do not correlate to the level of revenue 
in that period or in recent or future periods. 

For  the  year  ended  December  31,  2011  as  compared  to  2010,  total  marketing,  general  and  administrative  costs  increased  37.4% 
primarily due to the increased litigation expenses of $38.3 million related to ongoing major cases. Non-litigation related marketing, 
general and administrative costs increased for the year ended December 31, 2011 primarily due to the accrual of the CRI retention 
bonuses of $2.4 million and increased headcount related costs of $4.7 million from the increase in employees to support our business 
as well as higher consulting costs of $3.4 million and the acquisition costs related to CRI of $3.9 million, offset by the $5.0 million 
decrease  in  funding  for  our  2011  CIP,  which  is  lower  than  our  2010  CIP,  and  lower  stock-based  compensation  expense  of  $3.3 
million. 

For  the  year  ended  December  31,  2010  as  compared  to  2009,  total  marketing,  general  and  administrative  costs  decreased  6.8% 
primarily  due to  lower  litigation  expenses. Non-litigation related  marketing, general  and  administrative  costs  increased for  the  year 
ended  December  31,  2010  primarily  due  to  funding  for  our  2010  CIP, which  included  the  employee  bonus related  to  the  Samsung

settlement,  increased  consulting  fees,  increased  general  legal  expenses  and  increased  headcount  in  corporate  development 
commencing in 2009 as a result of our strategic initiatives to identify and acquire additional technology opportunities. 

In  the  future, marketing,  general  and  administrative  costs  will  vary  from  period  to period  based on the  trade  shows,  advertising, 
legal, acquisition and other marketing and administrative activities undertaken, and the change in sales, marketing and administrative 
headcount  in  any  given  period.  Litigation  expenses  are  expected  to  vary  from  period  to  period  due  to  the  variability  of  litigation 
activities.

Costs  (recoveries)  of  restatement  and  related  legal  activities,  net,  consist  primarily  of  settlement  payments,  investigation,  audit, 
legal and other professional fees related to the 2006-2007 stock option investigation and the filing of the restated financial statements 
and related litigation. 

For  the  year  ended  December  31,  2011,  costs  of  restatement  and  related  legal  activities  were  $16.2  million  primarily  due  to  a 
settlement  payment  and  the  litigation  expense  associated  with  a  private  shareholder  lawsuit  related  to  the  2006-2007  stock  option 
investigation.  In  December  2011,  we  reached  a  settlement  agreement  that  resolved  the  matter  captioned  Stuart  J.  Steele,  et  al.  v. 
Rambus  Inc.,  et  al.,  where  we  have  agreed  to  settle  the  claims  against  us  and  the  individual  defendants  for  approximately  $10.9 
million.  Refer  to  Note  16,  “Litigation  and  Asserted  Claims,”  of  Notes  to  Consolidated  Financial  Statements  of  this  Form  10-K  for 
additional details. 

For  the  year  ended  December  31,  2010,  costs  of  restatement  and  related  legal  activities,  net,  were  $4.2  million  primarily  due  to 
litigation expense associated with the private shareholder lawsuit referred to above. In 2009, we recorded reimbursements of $12.3 
million from the insurance carriers and received $4.5 million from former Rambus executives as part of their settlement agreements 
with us in connection with the derivative and class action lawsuits in 2009. Until all the litigation and related issues are resolved, we 
anticipate that there could be additional amounts relating to these matters in the future.

The settlement with Samsung is a multiple element arrangement for accounting purposes. For a multiple element arrangement, we 
are required to determine the fair value of the elements. We considered several factors in determining the accounting fair value of the 
elements of the settlement with Samsung which included a third party valuation using an income approach, the Black-Scholes-Merton 
option  pricing  model  and  a  residual  approach  (collectively  the  “Fair  Value”).  The  total  gain  from  settlement  is  $133.0  million,  of 
which $6.2 million was recognized during the year ended December 31, 2011. The total gain from settlement related to the settlement 
with Samsung of $133.0 million has been recognized as of the end of the first quarter of 2011. The gain from settlement represents the 
Fair  Value  of  the  cash  consideration  allocated  to  the  resolution  of  the  antitrust  litigation  settlement  and  the  residual  value  of  other 
elements.

Interest income and other income (expense), net, consists primarily of interest income generated from investments in high quality 

fixed income securities offset by interest expense associated with our imputed facility lease obligations.  

Following  the  substantial  completion  of  construction  in  the  fourth  quarter  of  2010,  we  occupied  our  Sunnyvale  and  Brecksville 
facilities.  In  connection  with  the  application  of  FASB  authoritative  guidance  to  our  leases  of  the  new  facilities,  we  are  deemed,  in 
substance, to be the owner of the landlord’s buildings, and therefore the estimated fair value of our portion of the buildings is required 
to be capitalized on our books as a non-cash transaction, offset by a corresponding imputed financing obligation on our balance sheet. 
The imputed financing obligations are amortized using the effective interest method with the imputed interest rate of approximately 
10%. For the year ended December 31, 2011, we recognized $3.3 million of interest expense in connection with the imputed financing 
obligations in our statement of operations. For the year ended December 31, 2010, we recognized $0.4 million of interest expense in 
connection with the imputed financing obligations in our statement of operations. See Note 8, “Commitments and Contingencies,” of 
Notes to Consolidated Financial Statements of this Form 10-K for additional details. 

Interest expense on convertible notes consists of non-cash interest expense related to the amortization of the debt discount on the 
5% convertible senior notes due 2014 (the “2014 Notes”) and the zero coupon convertible senior notes due 2010 (the “2010 Notes”), 
which were repaid during the first quarter of 2010, as well as the coupon interest related to the 2014 Notes. We expect interest expense 
to  increase  steadily  as  the  2014  Notes  reach  maturity.  See  Note  15,  “Convertible  Notes,”  of  Notes  to  Consolidated  Financial 
Statements of this Form 10-K for additional details.

Our effective tax rate for the year ended December 31, 2011 is different from the U.S. statutory tax rate due to foreign withholding 
taxes, a full valuation allowance on our U.S. net deferred tax assets and foreign losses not benefitted, partially offset by foreign tax 
credits. Our effective tax rate for the year ended December 31, 2010 was different from the U.S. statutory tax due to a full valuation 
allowance on our U.S. net deferred tax assets, partially offset by foreign withholding taxes and state alternative minimum taxes. Our 
effective  tax  rate  for  the  year  ended  December 31,  2009  was  different  from  the  U.S. statutory  tax  rate  applied  to  our  pretax  loss 
primarily due to a full valuation allowance on our U.S. net deferred tax assets, foreign income taxes and state income taxes, partially 
offset by refundable research and development tax credits and carryback of net operating loss.  

For the year ended December 31, 2011, we paid withholding taxes of $16.6 million. We recorded a provision for income taxes of 

$17.3 million which is primarily comprised of withholding taxes, other foreign taxes and current state taxes.  

As  of  December  31,  2011,  we  continued  to  maintain  a  full  valuation  allowance  against  our  U.S.  net  deferred  tax  assets. 
Management periodically evaluates the realizability of our net deferred tax assets based on all available evidence, both positive and 
negative.  The  realization  of  net  deferred  tax  assets  is  dependent  on  our  ability  to  generate  sufficient  future  taxable  income  during 
periods prior to the expiration of tax statutes to fully utilize these assets. Based on all available evidence, we determined that it was not 
more  likely  than  not  that  the  deferred  tax  assets  would  be  realized.  Should  we  achieve  sustained  taxable  income  in  the  future,  we 
would release the valuation allowance to recognize the deferred tax assets consisting of future tax deductions, net operating loss and

Liquidity 

Our management continues to believe that total cash, cash equivalents and marketable securities will continue at adequate levels to 
finance our operations, projected capital expenditures and commitments for at least the next twelve months. Additionally, substantially 
all  of  our  cash  and  cash  equivalents  are  in  the  U.S.  Our  cash  needs  for  2011  were  funded  primarily  from  our  operating  activities, 
maturities  of  marketable  securities,  proceeds  from  the  landlord  for  tenant  improvements  related  to  the  lease  in  Sunnyvale  and  the 
issuance of common stock under our equity incentive plans. 

We currently anticipate that existing cash, cash equivalents and marketable securities balances and cash flows from operations will 
be adequate to meet our cash needs for at least the next 12 months. We do not anticipate any liquidity constraints as a result of either 
the  current  credit  environment  or  investment  fair  value  fluctuations.  Additionally,  we  have  the  intent  and  ability  to  hold  our  debt 
investments that have unrealized losses in accumulated other comprehensive loss for a sufficient period of time to allow for recovery 
of  the  principal  amounts  invested.  We  continually  monitor  the  credit  risk  in  our  portfolio  and  mitigate  our  credit  risk  exposures  in 
accordance  with  our  policies.  As  described  elsewhere  in  this  “Management’s  Discussion  and  Analysis  of  Financial  Condition  and 
Results of Operations” and this Annual Report on Form 10-K, we are involved in ongoing litigation related to our intellectual property 
and our past stock option investigation. Any adverse settlements or judgments in any of this litigation could have a material adverse 
impact on our results of operations, cash balances and cash flows in the period in which such events occur. 

Operating Activities 

Cash provided by operating activities of $53.0 million for the year ended December 31, 2011 was primarily attributable to changes 
in operating assets and liabilities and the net loss adjusted for non-cash items, including stock-based compensation expense, non-cash 
interest expense, depreciation and amortization expense. Changes in operating assets and liabilities for the year ended December 31, 
2011 primarily included increases in accounts payable, accrued litigation and decreases in prepaid expenses and other assets.  

Cash  provided  by  operating  activities  of  $235.2 million  in  the  year  ended  December 31,  2010  was  primarily  attributable  to  the 
signing of Samsung and Elpida. In total, Samsung and Elpida provided approximately $300.2 million of net operating cash flow after 
applicable foreign tax withholdings. Additionally cash provided by operating activities included increases in accrued salaries due to 
the 2010 CIP and bonus related to the Samsung Settlement which was offset by decreases in accrued litigation and accounts payable.  

Cash used in operating activities of $40.6 million in the year ended December 31, 2009 was primarily attributable to the net loss 
adjusted  for  certain  non-cash  items  including  stock-based  compensation  expense,  non-cash  interest  expense,  depreciation  and 
amortization  expense.  Changes  in  operating  assets  and  liabilities  which  included  decreases  in  accrued  litigation  expenses  due  to 
recognition  of  proceeds  of  $5.0  million  from  an  insurance  company  related  to  the  derivative  and  class  action  lawsuits  offset  by 
increases in accounts payable due to the timing of vendor payments.

Cash used in investing activities of $24.1 million for the year ended December 31, 2011 primarily consisted of cash paid for the 
acquisition of CRI of $167.4 million, net of cash acquired, and purchases of available-for-sale marketable securities of $174.0 million, 
partially  offset  by  proceeds  from  the  maturities  of  available-for-sale  marketable  securities  of  $337.9  million.  In  addition,  we  paid 
$19.4 million to acquire property and equipment, primarily computer equipment, machinery and software. 

Cash  used  in  investing  activities  of  approximately  $181.5  million  in  the  year  ended  December  31,  2010  primarily  consisted  of 
purchases of available-for-sale marketable securities of $428.8 million, partially offset by proceeds from the maturities of available-
for-sale  marketable  securities  of  $296.6  million  and  proceeds  from  the  sale  of  marketable  securities  of  $1.8  million.  We  also 
purchased patents and businesses for an aggregate price of approximately $24.8 million. Additionally, we paid $26.7 million for the 
build-out of the facilities in Sunnyvale, California and Brecksville, Ohio as well as to acquire computer software, computer hardware 
and machinery and equipment.  

Cash provided by investing activities of approximately $24.5 million in the year ended December 31, 2009 primarily consisted of 
proceeds from the maturities of available-for-sale marketable securities of $240.9 million, partially offset by purchases of available-
for-sale  marketable  securities  of  $183.2  million.  In  December  2009,  we  paid  $26.0  million  in  a  business  combination  to  acquire 
technology and a portfolio of advanced lighting and optoelectronics patents from GLT. Additionally, we paid $2.7 million to acquire 
property,  plant  and  equipment,  primarily  computer  software,  and  $2.5  million  for  intangible  assets.  We  also  made  a  $2.0  million 
investment in a non-marketable equity security of a technology company. 

Financing Activities 

Cash used in financing activities was $81.9 million for the year ended December 31, 2011 as a result of the repurchase in August 
2011 from Samsung of approximately 4.8 million shares of the Company’s common stock for an aggregate amount of $100.0 million 
pursuant  to  a  put  option  exercised  by  Samsung  in  accordance  with  the  terms  of  a  stock  purchase  agreement  with  Samsung  dated 
January 19, 2010. This is partially offset by $8.8 million received from the landlord for the tenant improvements related to the lease in 
Sunnyvale and $12.3 million from issuance of common stock under equity incentive plans. We also made payments of $2.5 million 
under  an  installment  payment  plan  to  acquire  intangible  assets  and  computer  software  and  $0.5  million  related  to  the  principal 
payments against the lease financing obligation. 

Cash used in financing activities was $127.5 million in the year ended December 31, 2010 was primarily due to the payment upon 
maturity of $137.0 million in face value of 2010 Notes and stock repurchased with an aggregate price of $195.1 million under our 
share  repurchase  program,  which  includes  the  shares  purchased  under  Share  Repurchase  Agreement  with  J.P.  Morgan,  offset  by 
proceeds received of $192.0 million from the issuance of common stock pursuant to the Stock Purchase Agreement with Samsung. 
Additionally,  we  received  approximately  $16.5  million  from  the  issuance  of  common  stock  under  equity  incentive  plans.  We  also 
made payments of $4.3 million under an installment payment plan to acquire intangible assets and computer software. 

Cash provided by financing activities was $188.9 million in the year ended December 31, 2009. We received proceeds of $168.2 
million from the issuance of 2014 Notes. Additionally, we received approximately $20.7 million from the issuance of common stock 
under equity incentive plans.  

Contractual Obligations  

On December 15, 2009, we entered into a definitive triple net space lease agreement with MT SPE, LLC (the “Landlord”) whereby 
we leased approximately 125,000 square feet of office space located at 1050 Enterprise Way in Sunnyvale, California (the “Sunnyvale 
Lease”). The office space is used for our corporate headquarters, as well as engineering, marketing and administrative operations and 
activities. We moved to the premises in the fourth quarter of 2010 following substantial completion of leasehold improvements. The 
Sunnyvale Lease has a term of 120 months from the commencement date. The initial annual base rent is $3.7 million, subject to a full 
abatement of rent for the first six months of the Sunnyvale Lease term, but with the rent for the seventh month paid in December 2009 
in order to gain access to the building. The annual base rent increases each year to certain fixed amounts over the course of the term as 
set forth in the Sunnyvale Lease and will be $4.8 million in the tenth year. In addition to the base rent, we also pay operating expenses, 
insurance expenses, real estate taxes and a management fee. We have two options to extend the Sunnyvale Lease for a period of 60 
months each and a one-time option to terminate the Sunnyvale Lease after 84 months in exchange for an early termination fee.

Since certain improvements constructed by us are considered structural in nature and given our responsibility for any cost overruns, 
for  accounting  purposes,  we  are  treated  in  substance  as  the  owner  of  the  construction  project  during  the  construction  period.  At 
completion,  we  concluded  that  we  retained  sufficient  continuing  involvement  to  preclude  de-recognition  of  the  building  under  the 
FASB  authoritative  guidance  applicable  to  the  sale  leasebacks  of  real  estate.  As  such,  we  continue  to  account  for  the  building  as 
owned real estate and to record an imputed financing obligation for our obligation to the legal owner.  

Pursuant  to  the  terms  of  the  Sunnyvale  Lease,  the  Landlord  agreed  to  reimburse  us  approximately  $9.1 million,  of  which  $0.3 
million  was  received  in  2010  and  $8.8  million  was  received  in  2011.  We  recognized  the  reimbursement  as  an  additional  imputed 
financing obligation under the FASB authoritative guidance as such payment from the Landlord is deemed to be an imputed financing 
obligation.  

On  November  4,  2011,  to  better  plan  for  future  expansion,  we  entered  into  an  Amended  Sunnyvale  Lease  (the  “Amended 
Sunnyvale  Lease”)  for  approximately  an  additional  31,000  square  feet  of  space.  Similar  to  the  original  Sunnyvale  Lease,  we  are 
required to construct the necessary tenant improvements for the premises to be capable of conducting business, which includes but is 
not limited to structural elements of the building. Additionally, the Landlord will provide a tenant improvement allowance estimated 
to be approximately $1.7 million. The Amended Sunnyvale Lease will have a commencement date of March 1, 2012 and will expire 
on June 30, 2020 (the same end date as the original Sunnyvale Lease). The base rent for the original Sunnyvale Lease will remain 
unchanged. The annual base rent for the Amended Sunnyvale Lease will initially be $1.1 million with rent abatement for the first five 
months  of  the  lease  term  and  increases  annually  over  the  course  of  the  term  as  set  forth  in  the  Amended  Sunnyvale  Lease  until  it 
reaches $1.3 million.  

Since certain improvements to be constructed by us are considered structural in nature and we are responsible for any cost overruns, 
for  accounting  purposes,  we  are  treated  in  substance  as  the  owner  of  the  construction  project  during  the  construction  period. 
Accordingly, as of December 31, 2011, for the Amended Sunnyvale Lease, we capitalized an estimated $6.2 million in property, plant 
and equipment based on the estimated fair value of the portion of the unfinished space along with a corresponding financing obligation 
for the same amount. 

Monthly lease payments on the facility are allocated between the land element of the lease (which is accounted for as an operating 
lease) and the imputed financing obligation. The imputed financing obligation is amortized using the effective interest method and the 
interest  rate  was  determined  in  accordance  with  the  requirements  of  sale  leaseback  accounting.  For  the  years  ended  December  31, 
2011  and  2010,  we  recognized  in  our  statement  of  operations  $3.2  million  and  $0.4  million,  respectively,  of  interest  expense  in 
connection  with  the  imputed  financing  obligation.  At  December  31,  2011  and  2010,  the  imputed  financing  obligation  balance  in 
connection  with  the  facility  was  $41.8  million  and  $27.3  million,  respectively,  which  was  primarily  classified  under  long-term 
imputed financing obligation. At the end of the initial lease term, should we decide not to renew the lease, we would reverse the equal 
amounts of the net book value of the building and the corresponding imputed financing obligation. 

On  March  8,  2010,  we  entered  into  a  lease  agreement  with  Fogg-Brecksville  Development  Co.  (the  “Ohio  Landlord”)  for 
approximately  25,000  square  feet  of  space  consisting  of  approximately  7,000  square  feet  of  office  area  and  approximately  18,000 
square  feet  of  warehouse  area,  located  in  Brecksville,  Ohio  (the  “Ohio  Lease”).  The  office  space  is  used  for  the  LDT  group’s 
engineering activities while the manufacturing space is used for the manufacturer of prototypes for the LDT group. The Ohio Lease 
was amended on September 29, 2011 to expand the facility to approximately 51,000 total square feet (the “Amended Ohio Lease”), 
consisting of two extensions to be constructed by the Ohio Landlord (“Expansion A” and “Expansion B”). Expansion A will consist of 
approximately 11,000 square feet of space and Expansion B will consist of approximately 15,000 square feet of space. The Amended 
Ohio Lease has a term of 84 months from the First Extended Term Commencement Date as defined below. The First Extended Term 
Commencement Date is the first day of the month following substantial completion of Expansion B. Upon substantial completion of 
Expansion A, the annual base rent will be increased to $0.6 million. Upon substantial completion of Expansion B, the annual base rent 
will  be  increased  to  $0.8  million.  The  annual  base  rent  increases  each  year  on  the  anniversary  date  of  the  First  Extended  Term 
Commencement Date by 2% over the course of the term as set forth in the Amended Ohio Lease. We have an option to extend the 
Amended Ohio Lease for a period of 60 months.  

We undertook a series of structural improvements to ready the initial space for our use in 2010 and the Ohio Landlord began the 
construction of the building extensions during the fourth quarter of 2011. Since certain improvements we constructed are considered 
structural in nature and we are responsible for any cost overruns, for accounting purposes, we are treated in substance as the owner of 

48 

 
 
 
 
 
 
 
 
the construction project during the construction period. At completion of the initial construction period in 2010, we concluded that we 
retained  sufficient  continuing  involvement  to  preclude  de-recognition  of  the  building  under  the  FASB  authoritative  guidance 
applicable to the sale leasebacks of real estate. As such, we continue to account for the building as owned real estate and to record an 
imputed financing obligation for our obligation to the legal owner. Additionally, as of December 31, 2011, we capitalized $1.2 million 
in property, plant and equipment based on the estimated fair value of the portion of the unfinished building extensions along with a 
corresponding financing obligation for the same amount. 

The lease payments are recorded as interest expense using the effective interest method over the term of the lease. For the years 
ended December  31,  2011  and  2010, we  recognized  in our  statement  of  operations $0.1  million  and $29  thousand, respectively, of 
interest  expense  in  connection  with  the  imputed  financing  obligation  on  the  Ohio  facility.  At  December  31,  2011  and  2010,  the 
imputed financing obligation balance in connection with the Ohio facility was $2.0 million and $0.8 million, respectively, which was 
classified under long-term imputed financing obligation. At the end of the intended use term, we would reverse the equal amounts of 
the net book value of the building and the corresponding imputed financing obligation. 

In  November  2011,  we  entered  into  a  lease  agreement  with  Metropolitan  Life  Insurance  (the  “SF  Landlord”)  for  approximately 
26,000 rentable square feet of office space in San Francisco, California (the “SF Lease”) to be used for the CRI group’s office space 
and which will be accounted as an operating lease. The SF Lease will have a commencement date of February 1, 2012 and a lease 
term of 75 months from the commencement date. The annual base rent for the SF Lease will be $0.9 million with a rent abatement for 
the first three months of the lease term and increases annually over the course of the term as set forth in the SF Lease until it reaches 
$1.0 million.  

In connection with the June 3, 2011 acquisition of CRI, we are obligated to pay retention bonuses to certain CRI employees and 
contractors,  subject  to  certain  eligibility  and  acceleration  provisions  including  the  condition  of  employment,  in  cash  for  the  first 
retention milestone and cash or stock at the Company’s election, for the following two payments. The three payments are to be equal 
amounts of approximately $16.7 million, on June 3, 2012, 2013 and 2014, respectively. The total retention bonus commitment is $50.0 
million and may be forfeited in part or whole by the covered employees and contractors upon voluntary departure from employment or 
discontinuation  of  services.  Any  amounts  forfeited  will  be  accelerated  and  paid  by  us  to  a  designated  charity.  See  Note  18, 
“Acquisition,” of Notes to Consolidated Financial Statements of this Form 10-K for additional information regarding the acquisition 
of CRI. 

On June 29, 2009, we entered into an Indenture with U.S. Bank, National Association, as trustee, relating to the issuance by us of 
$150.0 million aggregate principal amount of 5% convertible senior notes due June 15, 2014. On July 10, 2009, an additional $22.5 
million in aggregate principal amount of 2014 Notes were issued as a result of the underwriters exercising their overallotment option. 
The aggregate principal amount of the 2014 Notes outstanding as of December 31, 2011 was $172.5 million, offset by unamortized 
debt discount of $39.0 million in the accompanying consolidated balance sheets. The debt discount is currently being amortized over 
the  remaining  30  months  until  maturity  of  the  2014  Notes  on  June  15,  2014.  See  Note  15,  “Convertible  Notes,”  of  Notes  to 
Consolidated Financial Statements of this Form 10-K for additional details.

(1)   The  above  table  does  not  reflect  possible  payments  in  connection  with  uncertain  tax  benefits  of  approximately  $16.6  million 
including  $7.0  million  recorded  as  a  reduction  of  long-term  deferred  tax  assets  and  $9.6 million  in  long-term  income  taxes 
payable, as of December 30, 2011. As noted in Note 12, “Income Taxes” of Notes to Consolidated Financial Statements of this 
Form  10-K,  although  it  is  possible  that  some  of  the  unrecognized  tax benefits  could  be  settled  within  the  next  12 months,  we 
cannot reasonably estimate the outcome at this time.  

(2)  With  respect  to  the  imputed  financing  obligation,  the  main  components  of  the  difference  between  the  amount  reflected  in  the 
contractual  obligations  table  and  the  amount  reflected  on  the  Consolidated  Balance  Sheet  are  the  interest  on  the  imputed 
financing  obligation  and  the  estimated  common  area  expenses  over  the  future  periods.  Additionally,  the  amount  includes  the 
Amended Ohio Lease and the Amended Sunnyvale Lease. 

(3)   We have commitments with various software vendors for non-cancellable license agreements generally having terms longer than 
one year. The above table summarizes those contractual obligations as of December 31, 2011 which are also presented on our 
Consolidated Balance Sheet under current and other long-term liabilities. 

(4)  The CRI retention bonus payable on June 3, 2013 and 2014 will be paid in cash or stock at our election. 

Contingently Redeemable Common Stock 

On  January  19,  2010,  pursuant  to  the  terms  of  the  Stock  Purchase  Agreement,  Samsung  purchased  for  cash  from  us  9.6  million 
shares of our common stock (the “Shares”) with certain restrictions and put rights. The issuance of the Shares by us to Samsung was 
made through a private transaction. The Stock Purchase Agreement provided Samsung a one-time put right, beginning 18 months after 
the date of the Stock Purchase Agreement and extending to 19 months after the date of the Stock Purchase Agreement, to put back to 
us up to 4.8 million of the Shares at the original issue price of $20.885 per share (for an aggregate purchase price of up to $100.0 
million).  The  4.8  million  shares  were  recorded  as  contingently  redeemable  common  stock  on  the  consolidated  balance  sheet  as  of 
December 31, 2010. 

The Stock Purchase Agreement prohibited the transfer of the Shares by Samsung for 18 months after the date of the Stock Purchase 
Agreement,  subject  to  certain  exceptions.  After  expiration  of  the  transfer  restriction  period  on  July  18,  2011,  the  Stock  Purchase 
Agreement provided that Samsung could transfer a limited number of shares on a daily basis, provide us with a right of first offer for 
proposed transfers above certain daily limits, and, if no sale occurs to us under the right of first offer, allowed Samsung to transfer the 
Shares. Under the Stock Purchase Agreement, we also agreed that after the transfer restriction period, Samsung would have certain 
rights to register the Shares for sale under the securities laws of the United States, subject to customary terms and conditions. 

On  July  20,  2011,  we  received  notice  from  Samsung  exercising  their  option  to  put  back  to  us  approximately  4.8  million  of  the 
Shares for cash of $100.0 million. In August 2011, we paid $100.0 million to Samsung in exchange for the 4.8 million shares, which 
were retired. The difference between the amount recorded as contingently redeemable common stock and the cash paid was recorded 
as additional paid-in capital in our consolidated balance sheet. 

See Note 4, “Settlement Agreement with Samsung,” of Notes to Consolidated Financial Statements of this Form 10-K for further 

discussion. 

Share Repurchase Program 

In October 2001, our Board of Directors (the “Board”) approved a share repurchase program of our Common Stock, principally to 
reduce the dilutive effect of employee stock options. Under this program, the Board approved the authorization to repurchase up to 
19.0 million shares of our outstanding Common Stock over an undefined period of time. On February 25, 2010, the Board approved a 
new  share  repurchase  program  authorizing  the  repurchase  of  up  to  an  additional  12.5  million  shares. Share  repurchases  under  the 
program  may  be  made  through open  market,  established plan  or  privately  negotiated  transactions  in accordance  with  all  applicable 
securities  laws,  rules,  and  regulations. There  is  no  expiration  date  applicable  to  the  program. The  new  share  repurchase  program 
replaces the program authorized in October 2001. 

50 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
On  August  19,  2010,  we  entered  into  a  share  repurchase  agreement  (the  “Share  Repurchase  Agreement”)  with  J.P.  Morgan 
Securities Inc., as agent for JPMorgan Chase Bank, National Association, London Branch (“JP Morgan”) to repurchase approximately 
$90.0 million of our Common Stock, as part of our share repurchase program. Under the Share Repurchase Agreement, we pre-paid to 
JP  Morgan  the  $90.0  million  purchase  price  in  the  third  quarter  of  2010  for  the  Common  Stock  and  JP  Morgan  delivered  to  us 
approximately  4.8  million  shares  of  Common  Stock  at  an  average  price  of  $18.88  at  the  completion  of  the  Share  Repurchase 
Agreement in December 2010. 

For  the  year  ended  December  31,  2011,  we  did  not  repurchase  any  shares  of  our  Common  Stock  under  our  share  repurchase 
program.  For  the  year  ended December  31, 2010, we  repurchased  approximately  9.5  million  shares of our  Common  Stock with  an 
aggregate price of approximately $195.1 million, including the price paid pursuant to the Share Repurchase Agreement. For the year 
ended  December  31,  2009,  we  did  not  repurchase  any  shares  of  our  Common  Stock  under  our  share  repurchase  program.  As  of 
December  31,  2011,  we  had  repurchased  a  cumulative  total  of  approximately  26.3 million  shares  of  our  Common  Stock  with  an 
aggregate price of approximately $428.9 million since the commencement of the program in 2001. As of December 31, 2011, there 
remained an outstanding authorization to repurchase approximately 5.2 million shares of our outstanding Common Stock. 

We record stock repurchases as a reduction to stockholders’ equity. We record a portion of the purchase price of the repurchased 
shares as an increase to accumulated deficit when the price of the shares repurchased exceeds the average original proceeds per share 
received from the issuance of Common Stock. During the year ended December 31, 2011, we did not repurchase any Common Stock. 
During the year ended December 31, 2010, the cumulative price of the shares repurchased exceeded the proceeds received from the 
issuance of the same number of shares. The excess of $163.6 million was recorded as an increase to accumulated deficit for the year 
ended December 31, 2010. During the year ended December 31, 2009, we did not repurchase any Common Stock.

Critical Accounting Policies and Estimates 

The  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  are  based  upon  our  consolidated  financial 
statements,  which  have  been  prepared  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States.  The 
preparation  of  these  financial  statements  requires  us  to  make  estimates  and  judgments  that  affect  the  reported  amounts  of  assets, 
liabilities,  revenue  and  expenses,  and  related  disclosure  of  contingent  assets  and  liabilities.  On  an  ongoing  basis,  we  evaluate  our 
estimates, including those related to revenue recognition, investments, income taxes, litigation and other contingencies. We base our 
estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the 
results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent 
from other sources. Actual results may differ from these estimates under different assumptions or conditions. 

We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of 

our consolidated financial statements. 

Revenue Recognition 

Overview 

We recognize revenue when persuasive evidence of an arrangement exists, we have delivered the product or performed the service, 
the  fee  is  fixed  or  determinable  and  collection  is  reasonably  assured.  If  any  of  these  criteria  are  not  met,  we  defer  recognizing  the 
revenue until such time as all criteria are met. Determination of whether or not these criteria have been met may require us to make 
judgments, assumptions and estimates based upon current information and historical experience.  

Our  revenue  consists  of  royalty  revenue  and  contract  revenue.  Royalty  revenue  consists  of  patent  license  and  solutions  license 
royalties.  Contract  revenue  consist  of  fixed  license  fees,  fixed  engineering  fees  and  service  fees  associated  with  integration  of  our 
technology solutions into our customers’ products. Reseller arrangements generally provide for the pass-through of a percentage of the 

51 

 
 
  
 
 
 
 
 
 
 
 
 
 
fees paid to the reseller by the reseller’s customer for use of our patent and solutions licenses. We do not recognize revenue for these 
arrangements until we have received notice of revenue earned by and paid to the reseller, accompanied by the pass-through payment 
from the reseller. We do not pay commissions to the reseller for these arrangements. 

In addition, we may enter into certain settlements of patent infringement disputes. The amount of consideration received upon any 
settlement  (including  but  not  limited  to  past  royalty  payments,  future  royalty  payments  and  punitive  damages)  is  allocated  to  each 
element of the settlement based on the fair value of each element. In addition, revenues related to past royalties are recognized upon 
execution of the agreement by both parties, provided that the amounts are fixed or determinable, there are no significant undelivered 
obligations and collectability is reasonably assured. We do not recognize any revenues prior to execution of the agreement since there 
is no reliable basis on which we can estimate the amounts for royalties related to previous periods or assess collectability. Elements 
that are related to royalty revenue in nature (including but not limited to past royalty payments and future royalty payments) will be 
recorded as royalty revenue in the consolidated statements of operations. Elements that are not related to royalty revenue in nature 
(including but not limited to punitive damage and settlement) will be recorded as gain from settlement which is reflected as a separate 
line item within the operating expenses section in the consolidated statements of operations. 

Many of our licensees have the right to cancel their licenses. In such arrangements, revenue is only recognized to the extent that is 
consistent  with  the  cancellation  provisions.  Cancellation  provisions  within  such  contracts  generally  provide  for  a  prospective 
cancellation with no refund of fees already remitted by customers for products provided and payment for services rendered prior to the 
date  of  cancellation.  Unbilled  receivables  represent  enforceable  claims  and  are  deemed  collectible  in  connection  with  our  revenue 
recognition policy. 

Royalty Revenue 

We recognize royalty revenue upon notification by our licensees and when deemed collectible. The terms of the royalty agreements 
generally either require licensees to give us notification and to pay the royalties within 60 days of the end of the quarter during which 
the  sales  occur  or  are  based  on  a  fixed  royalty  that  is  due  within  45 days  of  the  end  of  the  quarter.  We  have  two  types  of  royalty 
revenue: (1) patent license royalties and (2) solutions license royalties. 

Patent licenses.  We license our broad portfolio of patented inventions to companies who use these inventions in the development 
and manufacture of their own products. Such licensing agreements may cover the license of part, or all, of our patent portfolio. The 
contractual  terms  of  the  agreements  generally  provide  for  payments  over  an  extended  period  of  time.  For  the  licensing  agreements 
with  fixed  royalty  payments,  we  generally  recognize  revenue  from  these  arrangements  as  amounts  become  due.  For  the  licensing 
agreements  with  variable  royalty  payments  which  can  be  based  on  either  a  percentage  of  sales  or  number  of  units  sold,  we  earn 
royalties at the time that the licensees’ sales occur. Our licensees, however, do not report and pay royalties owed for sales in any given 
quarter until after the conclusion of that quarter. As we are unable to estimate the licensees’ sales in any given quarter to determine the 
royalties due to us, we recognize royalty revenues based on royalties reported by licensees during the quarter and when other revenue 
recognition criteria are met.  

Solutions licenses.  We develop proprietary and industry-standard products that we provide to our customers under solutions license 
agreements. These arrangements include royalties, which can be based on either a percentage of sales or number of units sold. We 
earn  royalties  on  such  licensed  products  sold  worldwide  by  our  licensees  at  the  time  that  the  licensees’  sales  occur.  Our  licensees, 
however,  do  not  report  and  pay  royalties  owed  for  sales  in  any  given  quarter  until  after  the  conclusion  of  that  quarter.  As  we  are 
unable to estimate the licensees’ sales in any given quarter to determine the royalties due to us, we recognize royalty revenues based 
on royalties reported by licensees during the quarter and when other revenue recognition criteria are met.  

Contract Revenue 

We generally recognize revenue using percentage of completion for development contracts related to licenses of our solutions that 
involve significant engineering and integration services. For all license and service agreements accounted for using the percentage-of-
completion method, we determine progress to completion using input measures based upon contract costs incurred. We have evaluated 
use of output measures versus input measures and have determined that our output is not sufficiently uniform with respect to cost, time 
and effort per unit of output to use output measures as a measure of progress to completion. Part of these contract fees may be due 

52 

 
 
 
 
 
 
 
 
 
 
upon the achievement of certain milestones, such as provision of certain deliverables by us or production of chips by the licensee. The 
remaining fees may be due on pre-determined dates and include significant up-front fees. 

A provision for estimated losses on fixed price contracts is made, if necessary, in the period in which the loss becomes probable and 
can  be  reasonably  estimated.  If  we  determine  that  it  is  necessary  to  revise  the  estimates  of  the  total  costs  required  to  complete  a 
contract, the total amount of revenue recognized over the life of the contract would not be affected. However, to the extent the new 
assumptions regarding the total efforts necessary to complete a project are less than the original assumptions, the contract fees would 
be  recognized  sooner  than  originally  expected.  Conversely,  if  the  newly  estimated  total  efforts  necessary  to  complete  a  project  are 
longer than the original assumptions, the contract fees will be recognized over a longer period. 

If application of the percentage-of-completion method results in recognizable revenue prior to an invoicing event under a customer 
contract,  we  will  recognize  the  revenue  and  record  an  unbilled  receivable.  Amounts  invoiced  to  our  customers  in  excess  of 
recognizable  revenue  are  recorded  as  deferred  revenue.  The  timing  and  amounts  invoiced  to  customers  can  vary  significantly 
depending on specific contract terms and can therefore have a significant impact on deferred revenue or unbilled receivables in any 
given period. 

Litigation 

We are involved in certain legal proceedings, as discussed in Note 16, “Litigation and Asserted Claims,” of Notes to Consolidated 
Financial Statements of this Form 10-K. Based upon consultation with outside counsel handling our defense in these matters and an 
analysis of potential results, if we believe that a loss arising from such matters is probable and can be reasonably estimated, we record 
the  estimated  liability  in  its  consolidated  financial  statements.  If  only  a  range  of  estimated  losses  can  be  estimated,  we  record  an 
amount within the range that, in our judgment, reflects the most likely outcome; if none of the estimates within that range is a better 
estimate than any other amount, we record the liability at the low end of the range of estimates. Any such accrual would be charged to 
expense in the appropriate period. We recognize litigation expenses in the period in which the litigation services were provided. 

Goodwill and Intangible Assets 

Goodwill  represents  the  excess  of  the  purchase  price  over  the  fair  value  of  the  net  tangible  and  identifiable  intangible  assets 
acquired  in  a  business  combination.  Intangible  assets  resulting  from  the  acquisitions  of  entities  accounted  for  using  the  purchase 
method of accounting are estimated by management based on the fair value of net assets received. Identifiable intangible assets are 
comprised of patents, customer contracts and contractual relationships, existing technology, intellectual property and other intangible 
assets. Identifiable intangible assets are being amortized over the period of estimated benefit using principally the straight-line method 
and estimated useful lives ranging from one to ten years. Goodwill is not subject to amortization, but is subject to at least an annual 
assessment for impairment, applying a fair-value based test.  

We  evaluate  goodwill,  at  a  minimum,  on  an  annual  basis  and  whenever  events  and  changes  in  circumstances  suggest  that  the 
carrying amount may not be recoverable. Goodwill is allocation to various reporting units, which are generally an operating segment. 
The fair values of the reporting units are estimated using an income or discounted cash flows approach. If the carrying amount of the 
reporting  unit  exceeds  its  fair  value,  goodwill  is  considered  impaired  and  a  second  step  is  performed  to  measure  the  amount  of 
impairment loss, if any. 

Under the income approach, we measure fair value of the reporting unit based on a projected cash flow method using a discount 
rate determined by our management which is commensurate with the risk inherent in our current business model. Our discounted cash 
flow projections are based on our annual financial forecasts developed internally by management for use in managing our business. 

We  amortize  other  intangible  assets  over  their  estimated  useful  lives.  We  record  an  impairment  charge  on  these  assets  if  we 
determine that their carrying value may not be recoverable. The carrying value is not recoverable if it exceeds the undiscounted cash 
flows  resulting  from  the  use  of  the  asset  and  its  eventual  disposition.  Our  estimates  of  future  cash  flows  attributable  to  our  other 
intangible assets require significant judgment based on our historical and anticipated results and are subject to many factors. We assess 
the impairment of identifiable intangibles and long-lived assets whenever events or changes in circumstances indicate that the carrying 
value may not be recoverable or that the life of the asset may need to be revised. Factors we consider important which could trigger an 
impairment review include the following:  

53 

 
 
 
 
 
 
 
 
 
 
 
 
 
 

significant negative industry or economic trends;  
significant loss of clients; and  
significant changes in the manner of our use of the acquired assets or the strategy for our overall business. 

When  we  determine  that  the  carrying  value  of  intangibles  or  other  long-lived  assets  may  not  be  recoverable  based  upon  the 
existence of one or more of the above indicators of impairment, we measure the potential impairment based on a projected discounted 
cash  flow  method  using  a  discount  rate  determined  by  our  management  to  be  commensurate  with  the  risk  inherent  in  our  current 
business model. An impairment loss is recognized only if the carrying amount of the intangible asset or other long-lived asset is not 
recoverable and exceeds its fair value. Different assumptions and judgments could materially affect the calculation of the fair value of 
our other intangible assets and other long-lived assets. 

As of December 31, 2011, the fair value of our SBG reporting unit, with $4.5 million of goodwill, exceeded the carrying value of 
its net assets by approximately 328%; the fair value of our LDT reporting unit, with $13.7 million of goodwill, exceeded the carrying 
value of its net assets by approximately 29%; and the fair value of our CRI reporting unit, with $97.0 million of goodwill, exceeded 
the carrying value of its net assets by approximately 32%. To arrive at our cash flow projections utilized in the income approach, we 
used  the  reporting  unit’s forecast  of  estimated  operating  results  based on key  assumptions  such  as  long-term  revenue growth rates, 
costs and estimates of future anticipated changes in operating margins based on economic and market information. Key assumptions 
used to determine the fair value of our reporting units at December 31, 2011, were the expected after-tax cash flows for the forecast 
period and terminal year, terminal growth rates and weighted average cost of capital. Certain estimates used in the income approach 
involve  information  from  businesses  with  limited  financial  history  and  developing  revenue  models  which  increase  the  risk  of 
differences between the projected and actual performance. One of the key assumptions used in applying the income approach include 
discount  rates  which  ranged  from  13%  to  34%  depending  on  the  reporting  units’  overall  risk  profile  relative  to  other  guideline 
companies, the reporting units' respective industry as well as the visibility of future expected cash flows. It is reasonably possible that 
business  performance  significantly  below  our  expectations  or  a  deterioration  of  market  and  economic  conditions  could  occur.  This 
would  adversely  impact  our  ability  to  meet  our  projected  results,  which  could  cause  the  goodwill  in  any  of  our  reporting  units  to 
become impaired. Significant differences between these estimates and actual cash flows could materially affect our future financial 
results.  If  our  LDT  reporting  unit  is  not  successful  in  commercializing  new  business  arrangements,  or  if  we  are  unsuccessful  in 
renewing  our  license  agreements  for  the  SBG  and  CRI  reporting  units,  the  revenue  and  income  for  these  reporting  units  could 
adversely and materially deviate from their historical trends and could cause goodwill to become impaired. If we determine that our 
goodwill is impaired, we would be required to record a non-cash charge that could have a material adverse effect on our results of 
operations and financial position.  

Income Taxes 

As part of preparing our consolidated financial statements, we are required to calculate the income tax expense or benefit which 
relates to the pretax income or loss for the period. In addition, we are required to assess the realization of the deferred tax asset or 
liability to be included on the consolidated balance sheet as of the reporting dates. 

As  of  December 31,  2011,  our  consolidated  balance  sheet  included  net  deferred  tax  assets,  before  valuation  allowance,  of 
approximately  $149.3 million, which consists of net operating loss carryovers, tax credit carryovers, amortization, employee stock-
based compensation expenses and certain liabilities, partially reduced by deferred tax liabilities associated with the convertible debt 
instruments that may be settled in cash upon conversion, including partial cash settlements. For the year ended December 31, 2011, a 
valuation  allowance  of  $141.0  million  reduced  net  deferred  tax  assets  to  $8.3  million.  Management  periodically  evaluates  the 
realizability of our net deferred tax assets based on all available evidence, both positive and negative. The realization of net deferred 
tax assets is dependent on our ability to generate sufficient future taxable income during periods prior to the expiration of tax statutes 
to  fully  utilize  these  assets.  Our  forecasted  future  operating  results  are  highly  influenced  by,  among  other  factors,  assumptions 
regarding  (1) our  ability  to  achieve  our  forecasted  revenue,  (2) our  ability  to  effectively  manage  our  expenses  in  line  with  our 
forecasted revenue and (3) general trends in the semiconductor industry. 

We weighed both positive and negative evidence and determined that there is a continued need for a valuation allowance due to 
projected future losses, which we considered significant negative evidence. Though considered positive evidence, projected income 
from potential favorable patent and related settlement litigation were not included in the determination for the valuation allowance due 

54 

 
 
  
 
 
 
 
 
 
to our inability to reliably estimate and objectively verify the timing and amounts of such settlements. Even though we are no longer 
in  a  cumulative  tax  loss  position  for  the  last  twelve  quarters  primarily  due  to  certain  discrete  positive  events,  the  projection  of 
significant future losses is a negative factor that outweighs the positive factors leading to a conclusion that a release of the valuation 
allowance  is  not  yet  appropriate.  If  any  settlement  income  is  realized,  we  will  reassess  our  position  on  maintaining  the  valuation 
allowance. 

Tax  attributes  related  to  stock  option  windfall  deductions  are  not  to  be  recognized  until  they  result  in  a  reduction  of  cash  taxes 

payable. The benefit of these excess tax benefits will be recorded to equity when they reduce cash taxes payable. 

The calculation of our tax liabilities involves uncertainties in the application of complex tax law and regulations in a multitude of 
jurisdictions.  Although  FASB  Accounting  Standards  Codification  (“ASC”)  740  Income  Taxes,  provides  further  clarification  on  the 
accounting  for  uncertainty  in  income  taxes,  significant  judgment  is  required  by  management.  If  the  ultimate  resolution  of  tax 
uncertainties is different from what is currently estimated, a material impact on income tax expense could result. 

Stock-Based Compensation 

We maintained stock plans covering a broad range of potential equity grants including stock options, nonvested equity stock and 
equity stock units and performance based instruments. In addition, we sponsor an Employee Stock Purchase Plan (“ESPP”), whereby 
eligible employees are entitled to purchase Common Stock semi-annually, by means of limited payroll deductions, at a 15% discount 
from the fair market value of the Common Stock as of specific dates. 

The  accounting  guidance  for  share-based  payments  requires  the  measurement  and  recognition  of  compensation  expense  in  our 
statement  of  operations  for  all  share-based  payment  awards  made  to  our  employees,  directors  and  consultants  including  employee 
stock options, nonvested equity stock and equity stock units, and employee stock purchase grants. Stock-based compensation expense 
is measured at grant date, based on the estimated fair value of the award, reduced by an estimate of the annualized rate of expected 
forfeitures,  and  is  recognized  as  expense  over  the  employees’  expected  requisite  service  period,  generally  using  the  straight-line 
method. In addition, the accounting guidance for share-based payments requires the benefits of tax deductions in excess of recognized 
compensation  expense  to  be  reported  as  a  financing  cash  flow,  rather  than  as  an  operating  cash  flow  as  prescribed  under  previous 
accounting rules. Our forfeiture rate represents the historical rate at which our stock-based awards were surrendered prior to vesting. 
The  accounting  guidance  for  share-based  payments  requires  forfeitures  to  be  estimated  at  the  time  of  grant  and  revised  on  a 
cumulative basis, if necessary, in subsequent periods if actual forfeitures differ from those estimates. See Note 9, “Equity Incentive 
Plans  and  Stock-Based  Compensation,”  of  Notes  to  Consolidated  Financial  Statements  of  this  Form  10-K  for  more  information 
regarding the valuation of stock-based compensation. 

Marketable Securities 

Available-for-sale securities are carried at fair value, based on quoted market prices, with the unrealized gains or losses reported, 
net of tax, in stockholders’ equity as part of accumulated other comprehensive income (loss). The amortized cost of debt securities is 
adjusted for amortization of premiums and accretion of discounts to maturity, both of which are included in interest and other income, 
net. Realized gains and losses are recorded on the specific identification method and are included in interest and other income, net. We 
review  our  investments  in  marketable  securities  for  possible  other  than  temporary  impairments  on  a  regular  basis.  If  any  loss  on 
investment is believed to be other than temporary, a charge will be recognized in operations. In evaluating whether a loss on a debt 
security  is  other  than  temporary,  we  consider  the  following  factors:  1)  our  intent  to  sell  the  security,  2)  if  we  intend  to  hold  the 
security,  whether  or  not  it  is  more  likely  than  not  that  we  will  be  required  to  sell  the  security  before  recovery  of  the  security’s 
amortized  cost  basis  and  3)  even  if  we  intend  to  hold  the  security,  whether  or  not  we  expect  the  security  to  recover  the  entire 
amortized cost basis. Due to the high credit quality and short term nature of our investments, there have been no other than temporary 
impairments  recorded  to  date.  The  classification  of  funds  between  short-term  and  long-term  is  based  on  whether  the  securities  are 
available for use in operations or other purposes.

may be settled in cash upon conversion, including partial cash settlement.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk 

We are exposed to financial market risks, primarily arising from the effect of interest rate fluctuations on our investment portfolio. 
Interest  rate  fluctuation  may  arise  from  changes  in  the  market’s  view  of  the  quality  of  the  security  issuer,  the  overall  economic 
outlook, and the time to maturity of our portfolio. We mitigate this risk by investing only in high quality, highly liquid instruments. 
Securities with original maturities of one year or less must be rated by two of the three industry standard rating agencies as follows: 
A1 by Standard & Poor’s, P1 by Moody’s and/or F-1 by Fitch. Securities with original maturities of greater than one year must be 
rated by two of the following industry standard rating agencies as follows: AA- by Standard & Poor’s, Aa3 by Moody’s and/or AA- 
by  Fitch.  By  corporate  investment  policy,  we  limit  the  amount  of  exposure  to  $15.0  million  or  10%  of  the  portfolio,  whichever  is 
lower, for any single non-U.S. Government issuer. A single U.S. Agency can represent up to 25% of the portfolio. No more than 20% 
of  the  total  portfolio  may  be  invested  in  the  securities  of  an  industry  sector,  with  money  market  fund  investments  evaluated 
separately. Our  policy  requires  that  at  least  10%  of  the  portfolio be  in  securities  with  a  maturity  of  90  days  or  less. We  may  make 
investments  in  U.S.  Treasuries,  U.S.  Agencies,  corporate  bonds  and  municipal  bonds  and  notes  with  maturities  up  to  36  months. 
However, the bias of our investment portfolio is shorter maturities. All investments must be U.S. dollar denominated. Additionally, we 
have no significant exposure to European sovereign debt. 

We invest our cash equivalents and marketable securities in a variety of U.S. dollar financial instruments such as U.S. Treasuries, 
U.S.  Government  Agencies,  commercial  paper  and  corporate  notes.  Our  policy  specifically  prohibits  trading  securities  for  the  sole 
purposes  of  realizing  trading  profits.  However,  we  may  liquidate  a  portion  of  our  portfolio  if  we  experience  unforeseen  liquidity 
requirements. In such a case, if the environment has been one of rising interest rates we may experience a realized loss, similarly, if 
the  environment  has been one  of declining interest  rates we  may  experience  a realized  gain. As of December  31, 2011, we had an 
investment portfolio of fixed income marketable securities of $264.7 million including cash equivalents. If market interest rates were 
to increase immediately and uniformly by 1.0% from the levels as of December 31, 2011, the fair value of the portfolio would decline 
by approximately $0.3 million. Actual results may differ materially from this sensitivity analysis. 

The table below summarizes the amortized cost, fair value, unrealized gains (losses) and related weighted average interest rates for 

our cash equivalents and marketable securities portfolio as of December 31, 2011 and December 31, 2010:

The fair value of our convertible notes is subject to interest rate risk, market risk and other factors due to the convertible feature. 
The fair value of the convertible notes will generally increase as interest rates fall and decrease as interest rates rise. In addition, the 
fair  value  of  the  convertible  notes  will  generally  increase  as  our  common  stock  price  increases  and  will  generally  decrease  as  our 
common stock price declines in value. The interest and market value changes affect the fair value of our convertible notes but do not 
impact our financial position, cash flows or results of operations due to the fixed nature of the debt obligation. Additionally, we do not 
carry  the  convertible  notes  at  fair  value.  We  present  the  fair  value  of  the  convertible  notes  for  required  disclosure  purposes.  The

We invoice our customers in U.S. dollars. Although the fluctuation of currency exchange rates may impact our customers, and thus 
indirectly impact us, we do not attempt to hedge this indirect and speculative risk. Our overseas operations consist primarily of one 
design  center  in  India  and  small  business  development  offices  in  Germany,  Japan,  Korea  and  Taiwan.  We  monitor  our  foreign 
currency exposure; however, as of December 31, 2011, we believe our foreign currency exposure is not material enough to warrant 
foreign currency hedging.

Item 9A.  Controls and Procedures 

Evaluation of Disclosure Controls and Procedures 

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in the reports we file 
or submit pursuant to the Securities and Exchange Act of 1934 as amended (“Exchange Act”) is recorded, processed, summarized and 
reported  within  the  time  periods  specified  in  the  rules  and  forms  of  the  Securities  and  Exchange  Commission,  and  that  such 
information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, 
as appropriate, to allow timely decisions regarding required disclosure. 

Management, with the participation of the Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the 
design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act as of 
the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have 
concluded that, as of December 31, 2011, our disclosure controls and procedures were effective. 

The internal control over financial reporting related to the assets acquired under a business combination from CRI was excluded 
from  the  evaluation  of  the  effectiveness  of  the  Company's  disclosure  control  and  procedures  as  of  the  end  of  the  year  because  the 
business  was  acquired  in  a  business  combination  during  2011.  Total  assets,  revenues  and  operating  expenses  of  this  business 
combination represent approximately 37%, 6% and 12%, respectively, of the related consolidated financial statement amounts as of 
and for the year ended December 31, 2011.

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting  as  defined  in 
Rules 13a-15(f)  and  15d-15(f)  under  the  Exchange Act.  Our  internal  control  over financial  reporting  is  the  process designed  by, or 
under the supervision of, our Chief Executive Officer and Chief Financial Officer, and effected 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  generally  accepted  accounting  principles,  and  includes  those  policies  and 
procedures that: 

(i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and dispositions of 

assets; 

(ii) provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in 
accordance  with  generally  accepted  accounting  principles,  and  that  our  receipts  and  expenditures  are  being  made  only  in 
accordance with the authorization of our management and directors; and 

(iii) 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. 

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. 

Our management has excluded the business acquired from CRI from its assessment of internal control over financial reporting as of 
December 31, 2011 because it was acquired by the Company in a business combination during the year ended December 31, 2011. 
Total assets, revenues and operating expenses from this business combination represent 37%, 6% and 12%, respectively, of the related 
consolidated financial statement amounts as of and for the year ended December 31, 2011.  

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial 
Officer, we conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2011. In 
making  this  assessment,  our  management  used  the  criteria  set  forth  in  Internal  Control —  Integrated  Framework  issued  by  the 
Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (“COSO”).  Based  on  the  results  of  this  assessment, 
management  has  concluded  that,  as  of  December 31,  2011,  our  internal  control  over  financial  reporting  was  effective  based  on  the 
criteria in Internal Control — Integrated Framework issued by the COSO. 

The  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December 31,  2011  has  been  audited  by 

PricewaterhouseCoopers, LLP, an independent registered public accounting firm, as stated in their report which appears herein. 

Changes in Internal Control Over Financial Reporting 

There were no changes in internal control over financial reporting during the last fiscal quarter that has materially affected, or are 

reasonably likely to materially affect, our internal control over financial reporting.

To the Board of Directors and Stockholders of Rambus Inc.: 

Report of Independent Registered Public Accounting Firm 

    In  our  opinion,  the  consolidated  financial  statements  listed  in  the  index  appearing  under  Item 15  (a)(1)  present  fairly,  in  all 
material respects, the financial position of  Rambus Inc. and its subsidiaries at December 31, 2011 and December 31, 2010, and the 
results of their operations and their cash flows for each of the three years in the period ended December 31, 2011, in conformity with 
accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule 
listed in the index appearing under item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in 
conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, 
effective  internal  control  over  financial  reporting  as  of  December  31,  2011  based  on  criteria  established  in  Internal  Control  - 
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's 
management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control 
over  financial  reporting  and  for  its  assessment  of  the  effectiveness  of  internal  control  over  financial  reporting,  included  in 
Management's Report on Internal Control over Financial Reporting, under item 9A. Our responsibility is to express opinions on these 
financial statements, on the financial statement schedule, and on the Company's internal control over financial reporting based on our 
integrated  audits.  We  conducted  our  audits  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United  States).  Those  standards  require  that  we  plan  and  perform  the  audits  to  obtain  reasonable  assurance  about  whether  the 
financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in 
all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and 
disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and 
evaluating  the  overall  financial  statement  presentation.  Our  audit  of  internal  control  over  financial  reporting  included  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 (i) pertain to 
the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the 
company; (ii) 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  (iii) provide  reasonable  assurance  regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect 
on the financial statements. 

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

   As  described  in  Management's  Report  on  Internal  Control  over  Financial  Reporting,  management  has  excluded  the  business 
acquired from Cryptography Research Inc., from its assessment of internal control over financial reporting as of December 31, 2011 
because it was acquired by the Company in a business combination during the year ended December 31, 2011.  Total assets, revenues 
and  operating  expenses  of  this  business  combination  represent  approximately  37%,  6%  and  12%,  respectively,  of  the  related 
consolidated financial statement amounts as of and for the year ended December 31, 2011.

RAMBUS INC. 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1.  Formation and Business of the Company 

Rambus Inc. (the “Company” or “Rambus”) is a premier intellectual property and technology licensing company focusing on the 
creation, design, development and licensing of patented innovations, technologies and architectures that are foundational to nearly all 
digital electronics products and systems. The Company was incorporated in California in March 1990 and reincorporated in Delaware 
in  March  1997.  The  Company’s  mission  is  to  continuously  enrich  the  end-user  experience  of  electronic  system  through 
groundbreaking  innovations  and  technologies  designed  to  improve  the  performance,  power  efficiency,  time-to-market  and  cost-
effectiveness of the products, components and systems offered by market-leading companies in semiconductors, computing, tablets, 
handheld  devices,  mobile  applications,  gaming  and  graphics,  high  definition  televisions  (“HDTVs”)  and  displays,  general  lighting, 
cryptography and data security. The Company’s inventors and engineering teams focus on creating innovations designed to address 
the  most  challenging  demands  of  each  target  market  and  industry.  The  Company  generates  revenue  by  licensing  its  patented 
innovations and technologies to market-leading companies that provide their products to the end-user customers or consumers. The 
Company  believes  it  has  established  an  unparalleled  licensing  platform  and  business  model  that  will  continue  to  foster  the 
development  of  new  foundational  and  leading  innovations  and  technologies.  By  continuing  to  build  upon  this  platform,  the 
Company’s  goal  is  to  create  additional  licensing  opportunities,  and  thereby  perpetuate  strong  company  operating  performance  and 
long-term stockholder value. 

While  the  Company  has  historically  focused  its  efforts  in  the  development  of  technologies  for  electronics  memory  and  chip 
interfaces, it is in the process of expanding its portfolio of inventions and solutions to address additional markets in lighting, displays, 
chip  and  system  security,  digital  media,  as  well  as  new  areas  within  the  semiconductor  industry,  such  as  imaging  and  non-volatile 
memory.  The  Company  intends  to  continue  its  growth  into  new  technology  fields,  consistent  with  its  mission  to  create  great  value 
through its innovations and to make those technologies available through its licensing business model. Key to its efforts, both in its 
current businesses and in any new area of diversification, will be hiring and retaining world-class inventors, scientists and engineers to 
lead  the  development  of  inventions  and  technology  solutions  for  these  fields  of  focus,  and  the  management  and  business  support 
personnel necessary to execute of its plans and strategies.  

2.  Summary of Significant Accounting Policies 

Financial Statement Presentation 

The accompanying consolidated financial statements include the accounts of Rambus and its wholly owned subsidiaries, Rambus 
K.K., located in Tokyo, Japan, Cryptography Research, Inc., located in California, U.S.A., and Rambus Ltd., located in George Town, 
Grand Cayman Islands, British West Indies, which includes Rambus Chip Technologies (India) Private Limited, Rambus Deutschland 
GmbH, located in Pforzheim, Germany, and Rambus Korea, Inc., located in Seoul, Korea. In addition, Rambus International Ltd. and 
Rambus Delaware LLC are also subsidiaries. All intercompany accounts and transactions have been eliminated in the accompanying 
consolidated financial statements. Investments in entities with less than 20% ownership by Rambus and in which Rambus does not 
have the ability to significantly influence the operations of the investee are accounted for using the cost method and are included in 
other assets. 

Use of Estimates 

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make 
estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at 
the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could 
differ from those estimates. 

Reclassifications 

67 

 
 
 
 
 
 
 
 
 
 
 
 
 
Certain prior year balances were reclassified to conform to the current year’s presentation. None of these reclassifications had an 

impact on reported net income (loss) for any of the periods presented. 

Revenue Recognition 

Overview 

Rambus recognizes revenue when persuasive evidence of an arrangement exists, Rambus has delivered the product or performed 
the service, the fee is fixed or determinable and collection is reasonably assured. If any of these criteria are not met, Rambus defers 
recognizing  the  revenue  until  such  time  as  all  criteria  are  met.  Determination  of  whether  or  not  these  criteria  have  been  met  may 
require the Company to make judgments, assumptions and estimates based upon current information and historical experience.  

Rambus’ revenue consists of royalty revenue and contract revenue. Royalty revenue consists of patent license and solutions license 
royalties.  Contract  revenue  consist  of  fixed  license  fees,  fixed  engineering  fees  and  service  fees  associated  with  integration  of 
Rambus’  technology  solutions  into  its  customers’  products.  Reseller  arrangements  generally  provide  for  the  pass-through  of  a 
percentage of the fees paid to the reseller by the reseller’s customer for use of the Rambus’ patent and solutions licenses. Rambus does 
not recognize revenue for these arrangements until it has received notice of revenue earned by and paid to the reseller, accompanied 
by the pass-through payment from the reseller. Rambus does not pay commissions to the reseller for these arrangements. 

In addition, Rambus may enter into certain settlements of patent infringement disputes. The amount of consideration received upon 
any settlement (including but not limited to past royalty payments, future royalty payments and punitive damages) is allocated to each 
element of the settlement based on the fair value of each element. In addition, revenues related to past royalties are recognized upon 
execution of the agreement by both parties, provided that the amounts are fixed or determinable, there are no significant undelivered 
obligations  and  collectability  is  reasonably  assured.  Rambus  does  not  recognize  any  revenues  prior  to  execution  of  the  agreement 
since there is no reliable basis on which it can estimate the amounts for royalties related to previous periods or assess collectability. 
Elements that are related to royalty revenue in nature (including but not limited to past royalty payments and future royalty payments) 
will be recorded as royalty revenue in the consolidated statements of operations. Elements that are not related to royalty revenue in 
nature (including but not limited to punitive damage and settlement) will be recorded as gain from settlement which is reflected as a 
separate line item within the operating expenses section in the consolidated statements of operations. 

Many of Rambus’ licensees have the right to cancel their licenses. In such arrangements, revenue is only recognized to the extent 
that is consistent with the cancellation provisions. Cancellation provisions within such contracts generally provide for a prospective 
cancellation with no refund of fees already remitted by customers for products provided and payment for services rendered prior to the 
date  of  cancellation.  Unbilled  receivables  represent  enforceable  claims  and  are  deemed  collectible  in  connection  with  its  revenue 
recognition policy. 

Royalty Revenue 

Rambus  recognizes  royalty  revenue  upon  notification  by  its  licensees  and  when  deemed  collectible.  The  terms  of  the  royalty 
agreements  generally  either  require  licensees  to  give  Rambus notification  and  to pay  the  royalties  within  60 days  of  the  end  of  the 
quarter during which the sales occur or are based on a fixed royalty that is due within 45 days of the end of the quarter. Rambus has 
two types of royalty revenue: (1) patent license royalties and (2) solutions license royalties. 

Patent  licenses.  Rambus  licenses  its  broad  portfolio  of  patented  inventions  to  companies  who  use  these  inventions  in  the 
development  and  manufacture  of  their  own  products.  Such  licensing  agreements  may  cover  the  license  of  part,  or  all,  of  its  patent 
portfolio. The contractual terms of the agreements generally provide for payments over an extended period of time. For the licensing 
agreements with fixed royalty payments, Rambus generally recognizes revenue from these arrangements as amounts become due. For 
the licensing agreements with variable royalty payments which can be based on either a percentage of sales or number of units sold, 
Rambus earns royalties at the time that the licensees’ sales occur. Rambus’ licensees, however, do not report and pay royalties owed 
for sales in any given quarter until after the conclusion of that quarter. As Rambus is unable to estimate the licensees’ sales in any 
given quarter to determine the royalties due to Rambus, it recognizes royalty revenues based on royalties reported by licensees during 
the quarter and when other revenue recognition criteria are met.  

68 

 
 
 
 
 
 
 
 
 
 
 
 
Solutions  licenses.  Rambus develops proprietary  and  industry-standard products  that  it  provides  to  its  customers  under  solutions 
license agreements. These arrangements include royalties, which can be based on either a percentage of sales or number of units sold. 
Rambus earns royalties on such licensed products sold worldwide by its licensees at the time that the licensees’ sales occur. Rambus’ 
licensees, however, do not report and pay royalties owed for sales in any given quarter until after the conclusion of that quarter. As 
Rambus is unable to estimate the licensees’ sales in any given quarter to determine the royalties due to Rambus, it recognizes royalty 
revenues based on royalties reported by licensees during the quarter and when other revenue recognition criteria are met.  

Contract Revenue 

Rambus generally recognizes revenue using percentage of completion for development contracts related to licenses of its solutions 
that  involve  significant  engineering  and  integration  services.  For  agreements  accounted  for  using  the  percentage-of-completion 
method, Rambus determines progress to completion using input measures based upon contract costs incurred. Part of these contract 
fees may be due upon the achievement of certain milestones, such as provision of certain deliverables by Rambus or production of 
chips by the licensee. The remaining fees may be due on pre-determined dates and include significant up-front fees. 

A provision for estimated losses on fixed price contracts is made, if necessary, in the period in which the loss becomes probable and 
can  be  reasonably  estimated.  If  the  Company  determines  that  it  is  necessary  to  revise  the  estimates  of  the  total  costs  required  to 
complete a contract, the total amount of revenue recognized over the life of the contract would not be affected. However, to the extent 
the new assumptions regarding the total efforts necessary to complete a project are less than the original assumptions, the contract fees 
would be recognized sooner than originally expected. Conversely, if the newly estimated total efforts necessary to complete a project 
are longer than the original assumptions, the contract fees will be recognized over a longer period. 

If application of the percentage-of-completion method results in recognizable revenue prior to an invoicing event under a customer 
contract, Rambus will recognize the revenue and record an unbilled receivable. As of December 31, 2011 and 2010, the balances of 
unbilled receivable are not significant. Amounts invoiced to its customers in excess of recognizable revenue are recorded as deferred 
revenue. The timing and amounts invoiced to customers can vary significantly depending on specific contract terms and can therefore 
have a significant impact on deferred revenue or unbilled receivables in any given period. 

Litigation 

Rambus is involved in certain legal proceedings. Based upon consultation with outside counsel handling its defense in these matters 
and  an  analysis  of  potential  results,  if  Rambus  believes  that  a  loss  arising  from  such  matters  is  probable  and  can  be  reasonably 
estimated, Rambus records the estimated liability in its consolidated financial statements. If only a range of estimated losses can be 
determined,  Rambus  records  an  amount  within  the  range  that,  in  its  judgment,  reflects  the  most  likely  outcome;  if  none  of  the 
estimates within that range is a better estimate than any other amount, Rambus records the low end of the range. Any such accrual 
would be charged to expense in the appropriate period. Rambus recognizes litigation expenses in the period in which the litigation 
services were provided.  

Goodwill and Intangible Assets 

Goodwill  represents  the  excess  of  the  purchase  price  over  the  fair  value  of  the  net  tangible  and  identifiable  intangible  assets 
acquired  in  a  business  combination.  Intangible  assets  resulting  from  the  acquisitions  of  entities  accounted  for  using  the  purchase 
method of accounting are estimated by management based on the fair value of net assets received. Identifiable intangible assets are 
comprised of patents, customer contracts and contractual relationships, existing technology, intellectual property and other intangible 
assets. Identifiable intangible assets are being amortized over the period of estimated benefit using principally the straight-line method 
and  estimated  useful  lives  ranging  from  1  to  10  years.  Goodwill  is  not  subject  to  amortization,  but  is  subject  to  at  least  an  annual 
assessment for impairment, applying a fair-value based test.  

The Company evaluates goodwill, at a minimum, on an annual basis and whenever events and changes in circumstances suggest 
that the carrying amount may not be recoverable. Goodwill is allocated to various reporting units, which are generally an operating 
segment.  The  fair  values  of  the  reporting  units  are  estimated  using  an  income  or  discounted  cash  flows  approach.  If  the  carrying 
amount of the reporting unit exceeds its fair value, goodwill is considered impaired, and a second step is performed to measure the 
amount of impairments loss, if any.  

69 

 
 
 
 
 
 
 
 
 
 
 
Under the income approach, the Company measures fair value of the reporting unit based on a projected cash flow method using a 
discount  rate  determined  by  its  management  which  is  commensurate  with  the  risk  inherent  in  its  current  business  model.  The 
Company’s discounted cash flow projections are based on its annual financial forecasts developed internally by management for use in 
managing its business. Given the current economic environment and the uncertainties regarding the impact on its business, there can 
be no assurance that the estimates and assumptions made for purposes of the Company’s goodwill impairment testing in the fourth 
quarter of 2011 will prove to be accurate predictions of the future. If the Company’s assumptions regarding forecasted revenues or 
operating  margin  rates  are  not  achieved,  the  Company  may  be  required  to  record  goodwill  impairment  charges  in  future  periods, 
whether in connection with the next annual impairment testing or prior to that if any change constitutes a triggering event outside of 
the  period  when  the  annual  goodwill  impairment  test  is  performed.  It  is  not  possible  at  this  time  to  determine  if  any  such  future 
impairment charge would result or, if it does, whether such charge would be material. The Company believes that the assumptions and 
rates used in its impairment test are reasonable. However, they are judgmental, and variations in any of the assumptions or rates could 
result in materially different calculations of impairment amounts.  

Based on our valuation results, the Company determined that the fair value of its reporting units continued to exceed their carrying 

value. Therefore, management determined that no goodwill impairment charge was required as of December 31, 2011.  

The Company amortizes other intangible assets over their estimated useful lives. The Company records an impairment charge on 
these assets if it determines that their carrying value may not be recoverable. The carrying value is not recoverable if it exceeds the 
undiscounted cash flows resulting from the use of the asset and its eventual disposition. The Company’s estimates of future cash flows 
attributable to its other intangible assets require significant judgment based on its historical and anticipated results and are subject to 
many factors. The Company assesses the impairment of identifiable intangibles and long-lived assets whenever events or changes in 
circumstances indicate that the carrying value may not be recoverable or that the life of the asset may need to be revised. Factors that 
the Company considers important which could trigger an impairment review include the following:  

 
 
 

significant negative industry or economic trends;  
significant loss of clients; and  
significant changes in the manner of our use of the acquired assets or the strategy for our overall business.  

When the Company determines that the carrying value of intangibles or other long-lived assets may not be recoverable based upon 
the  existence  of  one  or  more  of  the  above  indicators  of  impairment,  the  Company  measures  the  potential  impairment  based  on  a 
projected discounted cash flow method using a discount rate determined by the Company to be commensurate with the risk inherent in 
the Company’s current business model. An impairment loss is recognized only if the carrying amount of the intangible asset or other 
long-lived  asset  is  not  recoverable  and  exceeds  its  fair  value.  Different  assumptions  and  judgments  could  materially  affect  the 
calculation of the fair value of the other intangible assets and other long-lived assets. During 2011, 2010 and 2009, Rambus did not 
recognize any impairment of its long-lived and intangible assets.  

Income Taxes 

Income  taxes  are  accounted  for  using  an  asset  and  liability  approach,  which  requires  the  recognition  of  deferred  tax  assets  and 
liabilities for expected future tax events that have been recognized differently in Rambus’ consolidated financial statements and tax 
returns. The measurement of current and deferred tax assets and liabilities is based on provisions of the enacted tax law and the effects 
of future changes in tax laws or rates are not anticipated. A valuation allowance is established when necessary to reduce deferred tax 
assets to amounts expected to be realized based on available evidence.  

In addition, the calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax 
regulations. As a result, the Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken or 
expected to be taken in its tax return. The Company considers many factors when evaluating and estimating its tax positions and tax 
benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. 

Stock-Based Compensation and Equity Incentive Plans 

70 

 
 
 
 
 
  
 
 
 
 
 
 
The Company maintained stock plans covering a broad range of equity grants including stock options, nonvested equity stock and 
equity  stock  units  and  performance  based  instruments.  In  addition,  the  Company  sponsors  an  Employee  Stock  Purchase  Plan 
(“ESPP”), whereby eligible employees are entitled to purchase Common Stock semi-annually, by means of limited payroll deductions, 
at a 15% discount from the fair market value of the Common Stock as of specific dates.  

Rambus  will  only  recognize  a  tax  benefit  from  stock-based  awards  in  additional  paid-in  capital  if  an  incremental  tax  benefit  is 
realized after all other tax attributes currently available have been utilized. In addition, Rambus has elected to account for the indirect 
effects of stock-based awards on other tax attributes, such as the research tax credits, through the consolidated statement of operations 
as part of the tax effect of stock-based compensation. 

 Cash and Cash Equivalents 

Cash equivalents are highly liquid investments with original maturity of three months or less at the date of purchase. The Company 
maintains  its  cash  balances  with  high  quality  financial  institutions.  Cash  equivalents  are  invested  in  highly-rated  and  highly-liquid 
money market securities and certain U.S. government sponsored obligations.  

Marketable Securities 

Available-for-sale securities are carried at fair value, based on quoted market prices, with the unrealized gains or losses reported, 
net of tax, in stockholders’ equity as part of accumulated other comprehensive income (loss). The amortized cost of debt securities is 
adjusted for amortization of premiums and accretion of discounts to maturity, both of which are included in interest and other income, 
net. Realized gains and losses are recorded on the specific identification method and are included in interest and other income, net. 
The Company reviews its investments in marketable securities for possible other than temporary impairments on a regular basis. If any 
loss on investment is believed to be a credit loss, a charge will be recognized in operations. In evaluating whether a credit loss on a 
debt  security  has  occurred,  the  Company  considers  the  following  factors:  1)  the  Company’s  intent  to  sell  the  security,  2)  if  the 
Company intends to hold the security, whether or not it is more likely than not that the Company will be required to sell the security 
before  recovery  of  the  security’s  amortized  cost  basis  and  3)  even  if  the  Company  intends  to  hold  the  security,  whether  or  not  the 
Company expects the security to recover the entire amortized cost basis. Due to the high credit quality and short term nature of the 
Company’s investments, there have been no credit losses recorded to date. The classification of funds between short-term and long-
term is based on whether the securities are available for use in operations or other purposes. 

Non-Marketable Securities 

The  Company  has  an  investment  in  a  non-marketable  security  of  a  private  company  which  is  carried  at  cost.  The  Company 
monitors the investment for other-than-temporary impairment and records appropriate reductions in carrying value when necessary. 
The non-marketable security is classified within other assets in the consolidated balance sheets. 

Fair Value of Financial Instruments 

   The carrying value of cash, cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair 
values due to their relatively short maturities as of December 31, 2011 and 2010. Marketable securities are comprised of available-for-
sale securities that are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive 
income (loss), a component of stockholders’ equity, net of tax. Fair value of the marketable securities is determined based on quoted 
market prices.  The fair market value of the Company's convertible notes fluctuates with interest rates and with the market price of the 
stock, but does not affect the carrying value of the debt on the balance sheet. 

Property, Plant and Equipment 

Property,  plant  and  equipment  includes  computer  equipment,  computer  software,  leasehold  improvements,  furniture  and  fixtures 
and  buildings.  Computer  equipment,  computer  software,  machinery  and  furniture  and  fixtures  are  stated  at  cost  and  generally 
depreciated on a straight-line basis over an estimated useful life of 3, 3 to 5, 7 and 3 years, respectively. The Company undertook a 
series  of  structural  improvements  to  ready  the  Sunnyvale  and  Brecksville  facilities  for  its  use.  The  Company  concluded  that  its 
requirement to fund construction costs and responsibility for cost overruns resulted in the Company being considered the owner of the 

71 

 
 
 
 
 
 
 
 
 
 
 
 
 
buildings  during  the  construction  period  for  accounting  purposes.  Following  substantial  completion  of  construction,  the  Company 
occupied  both  facilities.  At  completion,  the  Company  concluded  that  it  retained  sufficient  continuing  involvement  to  preclude  de-
recognition of the buildings under the FASB authoritative guidance applicable to sale leaseback for real estate. As such, the Company 
continues to account for the buildings as owned real estate and to record an imputed financing obligation for its obligation to the legal 
owners. The buildings will be depreciated on a straight-line basis over an estimated useful life of approximately 39 years. See Note 6, 
“Balance  Sheet  Details,”  and  Note  8,  “Commitments  and  Contingencies,”  for  additional  details.  Leasehold  improvements  are 
amortized on a straight-line basis over the shorter of their estimated useful lives or the initial terms of the leases. Upon disposal, assets 
and  related  accumulated  depreciation  are  removed  from  the  accounts  and  the  related  gain  or  loss  is  included  in  the  results  from 
operations. 

Segment Reporting 

Operating  segments  are  defined  as  components  of  an  enterprise  about  which  separate  financial  information  is  available  that  is 
evaluated  regularly  by  the  chief  operating  decision  makers  in  deciding  how  to  allocate  resources  and  in  assessing  performance. 
Rambus  has  one  reportable  segment:  SBG  which  focuses  on  the  design,  development  and  licensing  of  technology  that  is 
semiconductor  based.  All  other  remaining  operating  segments  did  not  meet  the  quantitative  thresholds  for  disclosure  as  reportable 
segments. In addition, Rambus operates in three geographic regions: North America, Asia and Europe. 

Research and Development 

Costs incurred in research and development, which include engineering expenses, such as salaries and related benefits, stock-based 
compensation, depreciation, professional services and overhead expenses related to the general development of Rambus’ products, are 
expensed  as  incurred.  Software  development  costs  are  capitalized  beginning  when  a  product’s  technological  feasibility  has  been 
established  and  ending  when  a  product  is  available  for  general  release  to  customers.  Rambus  has  not  capitalized  any  software 
development costs since the period between establishing technological feasibility and general customer release is relatively short and 
as such, these costs have not been significant. 

Computation of Earnings (Loss) Per Share 

Basic earnings (loss) per share is calculated by dividing the net income (loss) by the weighted average number of common shares 
outstanding during the period. Diluted earnings (loss) per share is calculated by dividing the earnings (loss) by the weighted average 
number of common shares and potentially dilutive securities outstanding during the period. Potentially dilutive common shares consist 
of incremental common shares issuable upon exercise of stock options, employee stock purchases, restricted stock and restricted stock 
units,  and shares  issuable upon  the  conversion of  convertible  notes.  The  dilutive  effect  of outstanding  shares  is  reflected  in diluted 
earnings per share by application of the treasury stock method. This method includes consideration of the amounts to be paid by the 
employees, the amount of excess tax benefits that would be recognized in equity if the instrument was exercised and the amount of 
unrecognized  stock-based  compensation  related  to  future  services.  No  potential  dilutive  common  shares  are  included  in  the 
computation  of  any  diluted  per  share  amount  when  a  net  loss  is  reported.  As  discussed  in  Note  4,  “Settlement  Agreement  with 
Samsung,”  the  Company  reported  shares  issued  to  Samsung  as  contingently  redeemable  common  stock  due  to  the  contractual  put 
rights associated with those shares. As such, the Company used the two-class method for reporting earnings per share for those periods 
where the contingently redeemable common stock were outstanding (during 2010 until August 2011). 

Comprehensive Income (Loss) 

Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other 
events and circumstances from non-owner sources, including foreign currency translation adjustments and unrealized gains and losses 
on marketable securities. Other comprehensive income (loss), net of tax, is presented in the consolidated statements of comprehensive 
income (loss). 

Credit Concentration 

As of December 31, 2011 and 2010, the Company’s cash, cash equivalents and marketable securities were invested with various 
financial institutions in the form of corporate notes, bonds and commercial paper, money market funds, U.S. government bonds and 

72 

 
 
 
 
 
 
 
 
 
 
 
 
notes,  and  municipal  bonds and notes.  The  Company’s  exposure  to  market  risk  for  changes  in  interest  rates  relates  primarily  to  its 
investment  portfolio.  The  Company  places  its  investments  with  high  credit  issuers  and,  by  investment  policy,  attempts  to  limit  the 
amount of credit exposure to any one issuer. As stated in the Company’s investment policy, it will ensure the safety and preservation 
of the Company’s invested funds by limiting default risk and market risk. The Company has no investments denominated in foreign 
country currencies and therefore is not subject to foreign exchange risk from these assets. 

The  Company  mitigates  default  risk  by  investing  in  high  credit  quality  securities  and  by  positioning  its  portfolio  to  respond 
appropriately to a significant reduction in a credit rating of any investment issuer or guarantor. The portfolio includes only marketable 
securities with active secondary or resale markets to enable portfolio liquidity. 

Foreign Currency Translation 

The Company’s foreign subsidiaries currently use the U.S. dollar as the functional currency. Remeasurement adjustments for non-
functional currency monetary assets and liabilities are translated into U.S. dollars at the exchange rate in effect at the balance sheet 
date.  Revenue,  expenses,  gains  or  losses  are  translated  at  the  average  exchange  rate  for  the  period,  and  non-monetary  assets  and 
liabilities are translated at historical rates. The remeasurement gains and losses of these foreign subsidiaries as well as gains and losses 
from  foreign  currency  transactions  are  included  in  other  expense,  net  in  the  consolidated  statements  of  operations,  and  are  not 
significant for any periods presented. 

Allowance for Doubtful Accounts 

Rambus’ allowance for doubtful accounts is determined using a combination of factors to ensure that Rambus’ trade and unbilled 
receivables balances are not overstated due to uncollectibility. The Company performs ongoing customer credit evaluation within the 
context  of  the  industry  in  which  it  operates,  does  not  require  collateral,  and  maintains  allowances  for  potential  credit  losses  on 
customer accounts when deemed necessary. A specific allowance for a doubtful account up to 100% of the invoice is provided for any 
problematic customer balances. Delinquent account balances are written-off after management has determined that the likelihood of 
collection is not possible. For all periods presented, Rambus had no allowance for doubtful accounts. 

3. Recent Accounting Pronouncement 

In  December  2011,  the  FASB  issued  Accounting  Standards  Update  (“ASU”)  No.  2011-11,  “Disclosures  about  Offsetting  Assets 
and Liabilities”. ASU 2011-11 will require the Company to disclose information about offsetting and related arrangements to enable 
users of its financial statements to understand the effect of those arrangements on its financial position. The new guidance is effective 
for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The disclosures 
required are to be applied retrospectively for all comparative periods presented. The Company does not expect that this guidance will 
have an impact on its financial position, results of operations or cash flows as it is disclosure-only in nature.  

In September 2011, the FASB amended its guidance to simplify how an entity tests goodwill for impairment. The amendment will 
allow  an  entity  to  first  assess  qualitative factors  to determine  whether it  is  necessary  to  perform  the  two-step quantitative  goodwill 
impairment test. An entity no longer will be required to calculate the fair value of a reporting unit unless the entity determines, based 
on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amendment becomes 
effective for the Company’s interim period ending March 31, 2012 and early adoption is permitted. The Company anticipates adopting 
this guidance in its fourth quarter of fiscal 2012 at the time it performs its annual goodwill test and does not expect that this standard 
will materially impact its financial position or results of operations. 

In  June  2011,  the  FASB  amended  its  guidance  on  the  presentation  of  comprehensive  income.  Under  the  amended  guidance,  an 
entity has the option to present comprehensive income in either one continuous statement or two consecutive financial statements. A 
single statement must present the components of net income and total net income, the components of other comprehensive income and 
total  other  comprehensive  income,  and  a  total  for  comprehensive  income.  In  a  two-statement  approach,  an  entity  must  present  the 
components of  net  income  and  total  net  income  in  the  first  statement.  That  statement  must  be  immediately  followed by  a financial 
statement  that  presents  the  components  of  other  comprehensive  income,  a  total  for  other  comprehensive  income,  and  a  total  for 
comprehensive  income.  The  option  under  current  guidance  that  permits  the  presentation  of  components  of  other  comprehensive 
income  as  part  of  the  statement  of  changes  in  stockholders’  equity  has  been  eliminated.  The  amendment  becomes  effective 

73 

 
 
 
 
 
 
 
 
 
 
 
retrospectively  for  the  Company’s  interim  period  ending  March  31,  2012.  Early  adoption  is  permitted.  The  Company  adopted  this 
guidance  and  presented  the  statement  of  comprehensive  income  (loss)  as  a  separate  statement  immediately  after  the  statement  of 
operations. 

In  May  2011,  the  FASB  amended  its  guidance  to  converge  fair  value  measurement  and  disclosure  guidance  about  fair  value 
measurement  under  U.S.  Generally  Accepted  Accounting  Principles  (“GAAP”)  with  International  Financial  Reporting  Standards 
(“IFRS”). IFRS is a comprehensive series of accounting standards published by the International Accounting Standards Board. The 
amendment changes the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing 
information about fair value measurements. For many of the requirements, the FASB does not intend for the amendment to result in a 
change in the application of the requirements in the current authoritative guidance. The amendment becomes effective prospectively 
for  the  Company’s  interim  period  ending  March  31,  2012.  Early  adoption  is  not  permitted.  The  Company  does  not  expect  the 
amendment to have a material impact on its financial position, results of operations or cash flows. 

4. Settlement Agreement with Samsung 

On January 19, 2010, the Company, Samsung and certain related entities of Samsung entered into a Settlement Agreement (the 
“Settlement Agreement”) to release all claims against each other with respect to all outstanding litigation between them and certain 
other potential claims. Under the Settlement Agreement, Samsung has paid the Company two installments of $200.0 million each in 
cash in the first quarter of 2010, and the parties released all claims against each other with respect to all outstanding litigation between 
them  and  certain  other  potential  claims.  Pursuant  to  the  Settlement  Agreement,  the  Company  and  Samsung  entered  into  a 
Semiconductor Patent License Agreement on January 19, 2010 (the “License Agreement”), under which Samsung licenses from the 
Company non-exclusive rights to certain Rambus patents and has agreed to pay the Company cash amounts equal to $25.0 million per 
quarter, commencing in the first quarter of 2010, subject to certain adjustments and conditions, over the next five years. In addition, as 
part  of  the  Settlement  Agreement,  Samsung  purchased  approximately  9.6  million  shares  of  common  stock  of  Rambus  for  cash 
pursuant to the terms of a Stock Purchase Agreement dated January 19, 2010 (the “Stock Purchase Agreement”), as described in more 
details  below.  Finally,  pursuant  to  the  Settlement  Agreement,  the  Company  and  Samsung  signed  a  non-binding  memorandum  of 
understanding relating to discussions around a new generation of memory technologies. On an aggregate basis, Samsung is expected 
to  make  payments  to  the  Company  totaling  approximately  $900.0  million  (subject  to  adjustments  per  the  terms  of  the  License 
Agreement)  from  these  agreements(collectively,  “Samsung  Settlement”),  less  the  $100.0  million  retirement  of  the  contingently 
redeemable common stock described below. 

Under the License Agreement, the Company has granted to Samsung and its subsidiaries (i) a paid-up perpetual patent license for 
certain  identified  Samsung  DRAM  products  (these  Samsung  DRAM  products  generally  include  all  existing  DRAM  products  aside 
from the Rambus proprietary products) and (ii) a five-year term patent license to all other semiconductor products. Each license is a 
non-exclusive, non-transferable, royalty-bearing, worldwide patent license, without the right to sublicense, solely under the applicable 
patent  claims  of  Rambus  for  such  licensed  products,  to  make  (including  have  made),  use,  sell,  offer  for  sale  and/or  import  such 
licensed  products  until  the  expiration  or  termination  of  the  license  pursuant  to  the  terms  of  the  License  Agreement. The  License 
Agreement requires that Samsung pay the Company cash payments over the next five years of (i) a fixed amount of $25.0 million each 
quarter during 2010 and the first two quarters of 2011, and (ii) thereafter, $25.0 million adjusted up or down based on certain levels of 
Samsung revenue for DRAM products licensed under the License Agreement for each quarter after 2010 and subject to a minimum of 
$10.0  million  and  a  maximum  of  $40.0  million  for  each  quarter. In  addition,  additional  payments  or  certain  adjustments  to  the 
payments by Samsung to the Company under the License Agreement may be due for certain acquisitions of businesses or assets by 
Samsung involving licensed products. The License Agreement and the licenses granted thereunder may be terminated upon a material 
breach  by  a  party  of  its  obligations  under  the  agreement,  a  bankruptcy  event  involving  a  party  or  a  change  of  control  of  Samsung 
subject to certain conditions. 

Under the Stock Purchase Agreement, on January 19, 2010, Samsung purchased for cash from the Company 9.6 million shares of 
common stock of the Company (the “Shares”) with certain restrictions and put rights. The number of shares issued was based on a 
price  per  share  equal  to  $20.885  (which  was  the  average  of  the  open  and  close  trading  price  of  Rambus  common  stock  on  The 
NASDAQ Global Select Market on January 15, 2010, the last trading day prior to the date of the Stock Purchase Agreement). The 
Shares represented approximately 8.3% of the total outstanding shares of Rambus common stock at that time after giving effect to the 
issuance thereof. The issuance of the Shares by the Company to Samsung was made through a private transaction. The Stock Purchase 
Agreement  provided  Samsung  a  one-time  put  right,  beginning  18  months  after  the  date  of  the  Stock  Purchase  Agreement  and 

74 

 
 
 
 
 
 
 
extending to 19 months after the date of the Stock Purchase Agreement, to elect to put back to the Company up to 4.8 million of the 
Shares at the original issue price of $20.885 per share (for an aggregate purchase price of up to $100.0 million). 

On July 20, 2011, the Company received notice from Samsung exercising their option to put back to the Company approximately 
4.8 million of the Shares for cash of $100.0 million. In August 2011, the Company paid $100.0 million to Samsung in exchange for 
the Shares which were retired. The difference between the amount recorded as contingently redeemable common stock and the cash 
paid was recorded as additional paid-in capital in the Company’s consolidated balance sheet. 

The Stock Purchase Agreement prohibits the transfer of the Shares by Samsung for 18 months after the date of the Stock Purchase 
Agreement, subject to certain exceptions. After expiration of the transfer restriction period, the Stock Purchase Agreement provides 
that  Samsung  may  transfer  a  limited  number  of  shares  on  a  daily  basis,  provides  Rambus  with  a  right  of  first  offer  for  proposed 
transfers above such daily limits, and, if no sale occurs to Rambus under the right of first offer, allows Samsung to transfer the Shares. 
Under  the  Stock  Purchase  Agreement,  the  Company  has  also  agreed  that  after  the  transfer  restriction  period,  Samsung  will  have 
certain rights to register the Shares for sale under the securities laws of the United States, subject to customary terms and conditions. 

In addition, until 18 months after the date of the Stock Purchase Agreement, subject to customary exceptions, Samsung is subject 
to  a  standstill  agreement  that  prohibits  Samsung  from,  among  other  things,  acquiring  additional  shares  of  common  stock  of  the 
Company, commencing or endorsing any tender offer or exchange offer for shares of common stock of the Company, participating in 
any  solicitation  of  proxies  with  respect  to  voting  any  shares  of  common  stock  of  the  Company,  or  announcing  or  submitting  any 
proposal  or  offer  concerning  any  extraordinary  transaction  involving  the  Company.  Samsung  is  also  subject  to  a  voting  agreement 
under the Stock Purchase Agreement that provides that Samsung will vote its Shares in favor of routine proposals (related to election 
of  directors,  certain  compensation  matters,  authorized  share  capital  increases  and  approval  of  the  independent  auditors)  that  are 
recommended  by  the  Board  of  Directors  of  the  Company  at  any  stockholder  meeting.  In  all  other  matters,  the  voting  agreement 
contained in the Stock Purchase Agreement requires that Samsung vote its Shares in the same proportion as the votes that are cast by 
all other holders of shares of common stock of the Company. The voting agreement under the Stock Purchase Agreement terminates 
(i)  with  respect  to  Shares  that  Samsung  transfers  in  accordance  with  the  provisions  of  the  Stock  Purchase  Agreement,  (ii)  upon  a 
change of control or bankruptcy event involving the Company or (iii) when Samsung owns less than 3% of the outstanding shares of 
common stock of the Company. 

The Samsung Settlement is a multiple element arrangement for accounting purposes. For the multiple element arrangement, the 
Company  identified  each  element  of  the  arrangement  and  determined  when  those  elements  should  be  recognized.  Using  the 
accounting guidance from multiple element revenue arrangements, the Company allocated the consideration to each element using the 
estimated fair value of the elements. The Company considered several factors in determining the accounting fair value of the elements 
of the Samsung Settlement which included a third party valuation using an income approach, the Black-Scholes option pricing model 
and  a  residual  approach  (collectively  the  “Fair  Value”).  The  inputs  and  assumptions  used  in  this  valuation  were  from  a  market 
participant  perspective  and  included  projected  revenue,  royalty  rates,  estimated  discount  rates,  useful  lives  and  income  tax  rates, 
among  others.  The  development  of  a  number  of  these  inputs  and  assumptions  in  the  model  requires  a  significant  amount  of 
management judgment and is based upon a number of factors, including the selection of industry comparables, market growth rates 
and  other  relevant  factors.  Changes  in  any  number  of  these  assumptions  may  have  had  a  substantial  impact  on  the  Fair  Value  as 
assigned to each element. These inputs and assumptions represent management’s best estimates at the time of the transaction.  

Based on the estimated Fair Value, the consideration of $900.0 million was allocated to the following elements:

The consideration of $900.0 million will be recognized in the Company’s financial statements as follows:  

 $575.0 million as revenue which represented the estimated Fair Value of the settlement of past infringement ($190.0 million) 

from the resolution of the infringement litigation and the patent license agreement ($385.0 million); 

 $133.0  million  to  gain  from  settlement  which  represented  the  Fair  Value  of  the  resolution  of  the  antitrust  litigation  ($85.0 
million)  and  the  residual  value  of  other  elements  ($48.0  million)  where  specific  fair  value  could  not  be  determined,  which 
included other claims and counter claims released; 

 $192.0  million  related  to  the  Stock  Purchase  Agreement  which  included  contingently  redeemable  common  stock  due  to  the 
restrictions  and  contractual  put  rights  associated  with  those  shares  ($113.5  million)  and  restricted  common  stock  issued  to 
Samsung ($78.5 million).  

During 2010, the Company received cash consideration of $500.0 million from Samsung. The amount allocated to the common 
stock issued to Samsung was allocated to contingently redeemable common stock ($113.5 million) and stockholders’ equity ($78.5 
million).  The  remaining  $308.0  million  was  allocated  between  revenue  ($181.2  million)  and  gain  from  settlement  ($126.8  million) 
based on the remaining elements’ estimated Fair Value. 

During  2011,  the  Company  received  cash  consideration  of  $99.4  million  from  Samsung,  which  was  adjusted  based  on  certain 
levels of Samsung revenue for DRAM products pursuant to the terms of the License Agreement. The amount was allocated between 
revenue ($93.2 million) and gain from settlement ($6.2 million) based on the estimated Fair Value for the remaining elements. 

The remaining $300.0 million is expected to be paid in successive quarterly payments of approximately $25.0 million (subject to 

adjustments per the terms of the License Agreement), concluding in the last quarter of 2014. 

The cumulative cash receipts through 2011 and the remaining future cash receipts from the agreements with Samsung are expected 

to be recognized as follows assuming no adjustments to the payments under the terms of the agreements:

The Company continues to invest in high quality, highly liquid debt securities that mature within three years. As of December 31, 
2011, these securities have a remaining maturity of less than one year. The Company holds all of its marketable securities as available-
for-sale,  marks  them  to  market,  and  regularly  reviews  its  portfolio  to  ensure  adherence  to  its  investment  policy  and  to  monitor 
individual investments for risk analysis, proper valuation, and unrealized losses that may be other than temporary. As of December 31, 
2011, certain marketable debt securities with a fair value of $137.1 million, which mature within one year, had insignificant unrealized 
losses. The unrealized loss, net, at December 31, 2011 was insignificant in relation to the Company’s total available-for-sale portfolio. 
The unrealized loss, net, can be primarily attributed to a combination of market conditions as well as the demand for and duration of 
the  Company’s  corporate  notes  and  bonds.  The  Company  has  no  intent  to  sell,  there  is  no  requirement  to  sell  and  the  Company 
believes that it can recover the amortized cost of these investments. The Company has found no evidence of impairment due to credit 
losses in its portfolio. Therefore, these unrealized losses were recorded in other comprehensive income (loss). However, the Company 
cannot provide any assurance that its portfolio of cash, cash equivalents and marketable securities will not be impacted by adverse 
conditions  in  the  financial  markets,  which may  require  the  Company  in  the  future  to record  an  impairment  charge for  credit  losses 
which could adversely impact its financial results. 

The estimated fair value of cash equivalents and marketable securities classified by date of contractual maturity and the length of 
time  that  the  securities  have  been  in  a  continuous  unrealized  loss  position  at  December  31,  2011  and  December  31,  2010  are  as

On December 15, 2009, the Company entered into a lease for office space in Sunnyvale, California to be used for the Company’s 
corporate  headquarters  functions,  as  well  as  engineering,  marketing  and  administrative  operations  and  activities. The  Company 
undertook  a  series  of  structural  improvements  to  ready  the  space  for  its  use.  The  Company  concluded  that  its  requirement  to  fund 
construction costs and responsibility for cost overruns resulted in the Company being considered the owner of the building during the 
construction period for accounting purposes. At completion, the Company concluded that it retained sufficient continuing involvement 
to preclude de-recognition of the building under the FASB authoritative guidance applicable to sale leasebacks of real estate. As such, 
the  Company  continues  to  account  for  the  building  as  owned  real  estate  and  to  record  an  imputed  financing  obligation  for  its 
obligation to the legal owner. The building is reflected as an asset on the Company’s balance sheet throughout the initial term of the 
lease, the period of intended use. The value of the building is comprised of the fair value of the unfinished building of $25.1 million, 
$1.5 million of interest on the building and $13.1 million of construction costs related to the build-out of the facility. The fair value of 
the unfinished building was determined using level 3 fair value inputs (defined as prices or valuation techniques that require inputs 
that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity)) and the cost 
approach which measures the value of an asset as the cost to reconstruct or replace it with another asset of like utility. 

At December 31, 2011 and December 31, 2010, net book values of the Sunnyvale facility of $39.1 million and $39.7 million were 
reflected as an asset on the Company’s balance sheet, respectively. The building is depreciated on a straight-line basis over a period of 
approximately 39 years. See Note 8, “Commitments and Contingencies,” for additional details. 

On November 4, 2011, to better plan for future expansion, the Company entered into an amended lease for additional office space 
in  Sunnyvale,  California.  The  Company  will  undertake  a  series  of  structural  improvements  to  ready  the  space  for  its  use.  The 
Company concluded that its requirement to fund construction costs and responsibility for cost overruns resulted in the Company being 
considered the owner of the building during the construction period for accounting purposes. Therefore, as of December 31, 2011, for 
the additional Sunnyvale office space, the Company capitalized approximately $6.2 million as construction in progress, based on the 
estimated fair value of the existing portion of the same unfinished building, along with a corresponding financing obligation for the 
building.  

Additionally, during 2010, the Company entered into a lease for office space in Brecksville, Ohio that is used for the LDT group. 
Subsequently,  in  2011,  the  Company  amended  the  lease  to  expand  the  facility  for  additional  warehouse  and  office  spaces.  The 
Company undertook a series of structural improvements to ready the initial space for its use in 2010 and the Ohio landlord began the 
construction  of  the  building  extensions  during  the  fourth  quarter  of  2011.  The  Company  concluded  that  its  requirement  to  fund 
construction costs for the initial space and responsibility for cost overruns resulted in the Company being considered the owner of the 
building  during  the  construction  periods  for  accounting  purposes.  At  completion  of  the  initial  construction  period  in  2010,  the 
Company  concluded  that  it  retained  sufficient  continuing  involvement  to  preclude  de-recognition  of  the  building  under  the  FASB 
authoritative  guidance  applicable  to  sale  leasebacks  of  real  estate.  As  such,  the  Company  continues  to  account  for  the  building  as 
owned real estate and to record an imputed financing obligation for its obligation to the legal owner. The value of the initial space is 
reflected  in  the  Company’s  balance  sheet  as  building  and  is  comprised  of  the  fair  value  of  the  initial  unfinished  building  of  $0.8 
million  and  $1.7  million  of  construction  costs  related  to  the  build-out  of  the  facility.  As  of  December  31,  2011,  the  value  of  the 
unfinished building extensions of $1.2 million is reflected as construction in progress in the Company’s balance sheet and is based on 
the  estimated  total  costs  incurred  by  the  Landlord  through  December  31,  2011.  The  fair  value  of  the  unfinished  building  was 
determined using level 3 fair value inputs (defined as prices or valuation techniques that require inputs that are both significant to the

fair value measurement and unobservable (i.e., supported by little or no market activity)) and the cost approach which measures the 
value of an asset as the cost to reconstruct or replace it with another asset of like utility. 

At December 31, 2011 and December 31, 2010, net building costs related to the initial Brecksville space of $2.3 million and $2.5 
million are reflected as an asset on the Company’s balance sheet, respectively. The building is depreciated on a straight-line basis over 
a period of approximately 39 years. See Note 8, “Commitments and Contingencies,” for additional details. 

Depreciation expense for the years ended December 31, 2011, 2010 and 2009 was $11.9 million, $10.1 million and $10.7 million, 

respectively.

The  favorable  contracts  (included  in  customer  contracts  and  contractual  relationships)  are  acquired  patent  licensing  agreements 
where the Company has no performance obligations. Cash received from these acquired favorable contracts will reduce the favorable 
contract intangible asset. During 2011, the Company received $2.3 million related to the favorable contracts. The estimated useful life 
is  based  on  expected  payment  dates  related  to  the  favorable  contracts.  The  group  of  purchased  intangible  assets  has  an  estimated 
weighted average useful life of approximately 7 years from the date of acquisition. Refer to Note 18, “Acquisitions” for additional 
details. 

In addition, the Company acquired other patents in 2011 aggregating $4.2 million, of which $1.2 million was paid in cash. During 

2010, the Company purchased patents of approximately $24.4 million through business and asset acquisitions.

Goodwill  represents  the  excess  of  the  purchase  price  over  the  fair  value  of  the  net  tangible  and  identifiable  intangible  assets 
acquired in each business combination. The Company performs its impairment analysis of goodwill on an annual basis during fourth 
quarter of the fiscal year unless conditions arise that warrant a more frequent evaluation. Goodwill is allocated to various reporting 
units,  which  are  generally  an  operating  segment.  Following  the  acquisition  of  CRI,  the  Company  has  four  reporting  units,  and 
goodwill has been allocated to three of the reporting units: SBG, LDT and CRI.  

The Company completed the first step of its annual goodwill impairment analysis related to its SBG, LDT and CRI reporting units 
as  of  December  31,  2011  and  found  no  instances  of  impairment  of  its  recorded  goodwill  of  $115.1  million.  The  utilization  of  the 
income approach to determine fair value requires estimates of future operating results and cash flows discounted using an estimated 
discount rate. The Company’s estimates result from an updated long-term financial forecast developed as part of its annual strategic 
planning cycle which it conducts every year. The Company’s estimates of discounted cash flows may differ from actual cash flows 
due to, among other things, economic conditions, changes to its business model or changes in operating performance. Additionally, 
certain  estimates  used  in  the  income  approach  involve  information  from  businesses  with  limited  financial  history  and  developing 
revenue models which increase the risk of differences between the projected and actual performance. If the Company’s assumptions 
regarding  forecasted  cash  flows  are  not  achieved,  the  Company  may  be  required  to  record  goodwill  impairment  charges  in  future 
periods.  It  is  not  possible  at  this  time  to  determine  if  any  such  future  impairment  charge  would  result  or,  if  it  does,  whether  such 
charge would be material. The Company believes that the assumptions and rates used in its impairment test are reasonable. However, 
they are judgmental, and variations in any of the assumptions or rates could result in materially different calculations of impairment 
amounts. 

8.  Commitments and Contingencies  

On  December  15,  2009,  the  Company  entered  into  a  definitive  triple  net  space  lease  agreement  with  MT  SPE,  LLC  (the 
“Landlord”)  whereby  it  leased  approximately  125,000  square  feet  of  office  space  located  at  1050  Enterprise  Way  in  Sunnyvale, 
California  (the  “Sunnyvale  Lease”).  The  office  space  is  used  for  the  Company’s  corporate  headquarters,  as  well  as  engineering, 
marketing and administrative operations and activities. The Company moved to the premises in the fourth quarter of 2010 following 
substantial completion of leasehold improvements. The Sunnyvale Lease has a term of 120 months from the commencement date. The 
initial annual base rent is $3.7 million, subject to a full abatement of rent for the first six months of the Sunnyvale Lease term, but with 
the rent for the seventh month paid in December 2009 in order to gain access to the building. The annual base rent increases each year 
to certain fixed amounts over the course of the term as set forth in the Sunnyvale Lease and will be $4.8 million in the tenth year. In 
addition to the base rent, the Company also pays operating expenses, insurance expenses, real estate taxes and a management fee. The 
Company  has  two  options  to  extend  the  Sunnyvale  Lease  for  a  period  of  60  months  each  and  a  one-time  option  to  terminate  the 
Sunnyvale Lease after 84 months in exchange for an early termination fee. 

Since certain improvements to be constructed by the Company are considered structural in nature and the Company is responsible 
for any cost overruns, for accounting purposes, the Company is treated in substance as the owner of the construction project during the 
construction  period.  At  completion,  the  Company  concluded  that  it  retained  sufficient  continuing  involvement  to  preclude  de-
recognition  of  the  building  under  the  FASB  authoritative  guidance  applicable  to  the  sale  leasebacks  of  real  estate.  As  such,  the 
Company continues to account for the building as owned real estate and to record an imputed financing obligation for its obligation to 
the legal owner.  

Pursuant to the terms of the Sunnyvale Lease, the Landlord has agreed to reimburse the Company approximately $9.1 million, of 
which $0.3 million was received in 2010 and $8.8 million was received in 2011. The Company recognized the reimbursement as an 
additional imputed financing obligation under the FASB authoritative guidance as such payment from the Landlord is deemed to be an 
imputed financing obligation.  

On November 4, 2011, to better plan for future expansion, the Company entered into an Amended Sunnyvale Lease (the “Amended 
Sunnyvale Lease”) for approximately an additional 31,000 square feet of space. Similar to the original Sunnyvale Lease, the Company 
is required to construct the necessary tenant improvements for the premises to be capable of conducting business, which includes but 
is not limited to structural elements of the building. Additionally, the Landlord will provide a tenant improvement allowance estimated 
to be approximately $1.7 million. The Amended Sunnyvale Lease will have a commencement date of March 1, 2012 and will expire 
on June 30, 2020 (the same end date as the original Sunnyvale Lease). The base rent for the original Sunnyvale Lease will remain 

81 

 
 
 
 
 
 
 
 
 
unchanged. The annual base rent for the Amended Sunnyvale Lease will initially be $1.1 million with rent abatement for the first five 
months  of  the  lease  term  and  increases  annually  over  the  course  of  the  term  as  set  forth  in  the  Amended  Sunnyvale  Lease  until  it 
reaches $1.3 million.  

Since certain improvements to be constructed by the Company are considered structural in nature and the Company is responsible 
for any cost overruns, for accounting purposes, the Company is treated in substance as the owner of the construction project during the 
construction period. Accordingly, as of December 31, 2011, for the Amended Sunnyvale Lease, the Company capitalized an estimated 
$6.2 million in property, plant and equipment based on the estimated fair value of the portion of the unfinished space along with a 
corresponding financing obligation for the same amount. 

Monthly lease payments on the facility are allocated between the land element of the lease (which is accounted for as an operating 
lease) and the imputed financing obligation. The imputed financing obligation is amortized using the effective interest method and the 
interest  rate  was  determined  in  accordance  with  the  requirements  of  sale  leaseback  accounting.  For  the  years  ended  December  31, 
2011 and 2010, the Company recognized in its statement of operations $3.2 million and $0.4 million, respectively, of interest expense 
in connection with the imputed financing obligation on the Sunnyvale facility. At December 31, 2011 and 2010, the imputed financing 
obligation balance in connection with the Sunnyvale facility was $41.8 million and $27.3 million, respectively, which was primarily 
classified under long-term imputed financing obligation. At the end of the initial lease term, should the Company decide not to renew 
the  lease,  the  Company  would  reverse  the  equal  amounts  of  the  net  book  value  of  the  building  and  the  corresponding  imputed 
financing obligation. 

On March 8, 2010, the Company entered into a lease agreement with Fogg-Brecksville Development Co. (the “Ohio Landlord”) for 
approximately  25,000  square  feet  of  space  consisting  of  approximately  7,000  square  feet  of  office  area  and  approximately  18,000 
square  feet  of  warehouse  area,  located  in  Brecksville,  Ohio  (the  “Ohio  Lease”).  The  office  space  is  used  for  the  LDT  group’s 
engineering activities while the manufacturing space is used for the manufacturer of prototypes for the LDT group. The Ohio Lease 
was amended on September 29, 2011 to expand the facility to approximately 51,000 total square feet (the “Amended Ohio Lease”), 
consisting of two extensions to be constructed by the Ohio Landlord (“Expansion A” and “Expansion B”). Expansion A will consist of 
approximately 11,000 square feet of space and Expansion B will consist of approximately 15,000 square feet of space. The Amended 
Ohio Lease has a term of 84 months from the First Extended Term Commencement Date as defined below. The First Extended Term 
Commencement Date is the first day of the month following substantial completion of Expansion B. Upon substantial completion of 
Expansion A, the annual base rent will be increased to $0.6 million. Upon substantial completion of Expansion B, the annual base rent 
will  be  increased  to  $0.8  million.  The  annual  base  rent  increases  each  year  on  the  anniversary  date  of  the  First  Extended  Term 
Commencement  Date  by  2%  over  the  course  of  the  term  as  set  forth  in  the  Amended  Ohio  Lease.  The  Company  has  an  option  to 
extend the Lease for a period of 60 months.  

The Company undertook a series of structural improvements to ready the initial space for its use in 2010 and the Ohio Landlord 
began the construction of the building extensions during the fourth quarter of 2011. Since certain improvements constructed by the 
Company  are  considered  structural  in  nature  and  the  Company  is  responsible  for  any  cost  overruns,  for  accounting  purposes,  the 
Company is treated in substance as the owner of the construction project during the construction period. At completion of the initial 
construction period in 2010, the Company concluded that it retained sufficient continuing involvement to preclude de-recognition of 
the building under the FASB authoritative guidance applicable to the sale leasebacks of real estate. As such, the Company continues to 
account  for  the  building  as  owned  real  estate  and  to  record  an  imputed  financing  obligation  for  its  obligation  to  the  legal  owner. 
Additionally, as of December 31, 2011, the Company capitalized $1.2 million in property, plant and equipment based on the estimated 
fair value of the portion of the unfinished building extensions along with a corresponding financing obligation for the same amount. 

The lease payments are recorded as interest expense using the effective interest method over the term of the lease. For the years 
ended  December  31,  2011  and  2010,  the  Company  recognized  in  its  statement  of  operations  $0.1  million  and  $29  thousand, 
respectively, of interest expense in connection with the imputed financing obligation on the Ohio facility. At December 31, 2011 and 
2010, the imputed financing obligation balance in connection with the Ohio facility was $2.0 million and $0.8 million, respectively, 
which was classified under long-term imputed financing obligation. At the end of the intended use term, the Company would reverse 
equal amounts of the net book value of the building and the corresponding imputed financing obligation. 

In  November  2011,  the  Company  entered  into  a  lease  agreement  with  Metropolitan  Life  Insurance  (the  “SF  Landlord”)  for 
approximately 26,000 rentable square feet of office space in San Francisco, California (the “SF Lease”) to be used for the CRI group’s 

82 

 
 
 
 
 
 
 
 
office space and which will be treated as an operating lease. The SF Lease will have a commencement date of February 1, 2012 and a 
lease  term  of  75  months  from  the  commencement  date.  The  annual  base  rent  for  the  SF  Lease  will  be  $0.9  million  with  a  rent 
abatement for the first three months of the lease term and increases annually over the course of the term as set forth in the SF Lease 
until it reaches $1.0 million.  

In  connection  with  the  June  3,  2011  acquisition  of  CRI,  the  Company  is  obligated  to  pay  a  retention  bonus  to  certain  CRI 
employees and contractors, subject to certain eligibility and acceleration provisions including the condition of employment, in three 
equal amounts of approximately $16.7 million, with the first payment paid in cash and the remaining payments in cash or stock at the 
Company’s election, on June 3, 2012, 2013 and 2014, respectively. The total retention bonus commitment is $50.0 million and may be 
forfeited in part or whole by the covered employees and contractors upon voluntary departure from employment or discontinuation of 
services. Any amounts forfeited will be accelerated and paid by the Company to a designated charity. See Note 18, “Acquisitions,” for 
additional information regarding the acquisition of CRI. 

On June 29, 2009, the Company entered into an Indenture with U.S. Bank, National Association, as trustee, relating to the issuance 
by the Company of $150.0 million aggregate principal amount of the 2014 Notes. On July 10, 2009, an additional $22.5 million in 
aggregate  principal  amount  of  2014  Notes  were  issued  as  a  result  of  the  underwriters  exercising  their  overallotment  option.  The 
aggregate principal amount of the 2014 Notes outstanding as of December 31, 2011 was $172.5 million, offset by unamortized debt 
discount of $39.0 million in the accompanying consolidated balance sheets. The debt discount is currently being amortized over the 
remaining 30 months until maturity of the 2014 Notes on June 15, 2014. See Note 15, “Convertible Notes,” for additional details.

(1)   The  above  table  does  not  reflect  possible  payments  in  connection  with  uncertain  tax  benefits  of  approximately  $16.6  million 
including  $7.0 million  recorded  as  a  reduction  of  long-term  deferred  tax  assets  and  $9.6 million  in  long-term  income  taxes 
payable,  as  of  December  31,  2011.  As  noted  below  in  Note 12,  “Income  Taxes,”  although  it  is  possible  that  some  of  the 
unrecognized tax benefits could be settled within the next 12 months, the Company cannot reasonably estimate the outcome at 
this time.

(2)  With  respect  to  the  imputed  financing  obligation,  the  main  components  of  the  difference  between  the  amount  reflected  in  the 
contractual  obligations  table  and  the  amount  reflected  on  the  Consolidated  Balance  Sheets  are  the  interest  on  the  imputed 
financing  obligation  and  the  estimated  common  area  expenses  over  the  future  periods.  Additionally,  the  amount  includes  the 
Amended Ohio Lease and the Amended Sunnyvale Lease. 

(3)   The Company has commitments with various software vendors for non-cancellable license agreements generally having terms 
longer  than  one  year.  The  above  table  summarizes  those  contractual  obligations  as  of  December  31,  2011  which  are  also 
presented on the Company’s Consolidated Balance Sheet under current and other long-term liabilities. 

(4)  The CRI retention bonus payable on June 3, 2013 and 2014 will be paid in cash or stock at the Company’s election. 

Rent  expense  was  approximately  $2.7  million,  $6.8  million  and  $6.3 million  for  the  years  ended  December 31,  2011,  2010  and 

2009, respectively.

Indemnifications 

The  Company  enters  into  standard  license  agreements  in  the  ordinary  course  of  business.  Although  the  Company  does  not 
indemnify most of its customers, there are times when an indemnification is a necessary means of doing business. Indemnifications 
cover customers for losses suffered or incurred by them as a result of any patent, copyright, or other intellectual property infringement 
claim by any third party with respect to the Company’s products. The maximum amount of indemnification the Company could be 
required to make under these agreements is generally limited to fees received by the Company.  

Several  securities  fraud  class  actions,  private  lawsuits  and  shareholder  derivative  actions  were  filed  in  state  and  federal  courts 
against certain of the Company’s current and former officers and directors related to the stock option granting actions. As permitted 
under Delaware law, the Company has agreements whereby its officers and directors are indemnified for certain events or occurrences 
while the officer or director is, or was serving, at the Company’s request in such capacity. The term of the indemnification period is 
for  the  officer’s  or  director’s  term  in  such  capacity.  The  maximum  potential  amount  of  future  payments  the  Company  could  be 
required to make under these indemnification agreements is unlimited. The Company has a director and officer insurance policy that 
reduces  the  Company’s  exposure  and  enables  the  Company  to  recover  a  portion  of  future  amounts  to  be  paid.  As  a  result  of  these 
indemnification agreements, the Company continues to make payments on behalf of current and former officers. As of December 31, 
2011 and 2010, the Company had made cumulative payments of approximately $31.9 million and $15.7 million, respectively, on their 
behalf.  These  payments  were  recorded  under  costs  of  restatement  and  related  legal  activities  in  the  consolidated  statements  of 
operations. Also, in December 2011, the Company reached a settlement agreement that resolved the matter captioned Stuart J. Steele, 
et  al.  v.  Rambus  Inc.,  et  al.,  where  the  Company  has  agreed  to  settle  the  claims  against  it  and  the  individual  defendants  for 
approximately $10.9 million which was recorded under costs (recoveries) of restatement and related legal activities in the consolidated 
statements  of  operations.  Refer  to  Note  16,  “Litigation  and  Asserted  Claims,”  for  additional  details.  The  Company  has  received 
approximately $5.3 million from the former officers related to their settlement agreements with the Company in connection with the 
derivative and class action lawsuits which was comprised of approximately $4.5 million in cash received in the first quarter of 2009 as 
well  as  approximately  163,000  shares  of  the  Company’s  stock  with  a  value  of  approximately  $0.8  million  in  the  fourth  quarter  of 
2008.  Additionally,  as  of  December  31,  2011,  the  Company  has  received  $12.3  million  from  insurance  settlements  related  to  the 
defense of the Company, its directors and its officers which were recorded under costs (recoveries) of restatement and related legal 
activities in the consolidated statements of operations.  

9.  Equity Incentive Plans and Stock-Based Compensation 

Stock Option Plans 

The Company has three stock option plans under which grants are currently outstanding: the 1997 Stock Option Plan (the “1997 
Plan”),  the 1999 Non-statutory  Stock Option  Plan (the  “1999  Plan”)  and  the 2006  Equity  Incentive Plan  (the  “2006  Plan”). Grants 
under all plans typically have a requisite service period of 60 months, have straight-line or graded vesting schedules (the 1997 and 
1999 plans only) and expire not more than ten years from date of grant. Effective with stockholder approval of the 2006 Plan in May 
2006,  no  further  awards  are  being  made  under  the  1997  Plan  and  the  1999  Plan  but  the  plans  will  continue  to  govern  awards 
previously granted under those plans.  

The  2006  Plan  was  approved  by  the  stockholders  in  May  2006.  The  2006  Plan,  as  amended,  provides  for  the  issuance  of  the 
following  types  of  incentive  awards:  (i) stock  options;  (ii) stock  appreciation  rights;  (iii) restricted  stock;  (iv) restricted  stock  units; 
(v) performance shares and performance units; and (vi) other stock or cash awards. This plan provides for the granting of awards at 
less than fair market value of the common stock on the date of grant, but such grants would be counted against the numerical limits of 
available shares at a ratio of 1.5 to 1. The Board of Directors reserved 8,400,000 shares in March 2006 for issuance under this plan, 
subject to stockholder approval. Upon stockholder approval of this Plan on May 10, 2006, the 1997 Plan was replaced and the 1999 
Plan was terminated. On April 30, 2009, stockholders approved additional 6,500,000 shares for issuance under the 2006 Plan. Those 
who  will  be  eligible  for  awards  under  the  2006  Plan  include  employees,  directors  and  consultants  who  provide  services  to  the 
Company and its affiliates. These options typically have a requisite service period of 60 months, have straight-line vesting schedules, 

84 

 
 
 
 
 
 
 
 
 
 
and expire ten years from date of grant. The Board will periodically review actual share consumption under the 2006 Plan and may 
make a request for additional shares as needed. 

As of December 31, 2011, 2,812,876 shares of the 14,900,000 shares approved under the 2006 Plan remain available for grant. The 
2006 Plan is now the Company’s only plan for providing stock-based incentive compensation to eligible employees, executive officers 
and non-employee directors and consultants. 

A summary of shares available for grant under the Company’s plans is as follows:

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value for in-the-money options at December 31, 
2011,  based  on  the  $7.55  closing  stock  price  of  Rambus’  Common  Stock  on  December 30,  2011  on  The  NASDAQ  Global  Select 
Market, which would have been received by the option holders had all option holders exercised their options as of that date. The total 
number of in-the-money options outstanding and exercisable as of December 31, 2011 was 262,467 and 262,467, respectively.

During the three year period ended December 31, 2011, the Company had one employee stock purchase plan, the 2006 Employee 

Stock Purchase Plan.  

In  March  2006,  the  Company  adopted  the  2006  Employee  Stock  Purchase  Plan,  as  amended  (the  “2006  Purchase  Plan”)  and 
reserved 1,600,000 shares, subject to stockholder approval which was received on May 10, 2006. Employees generally will be eligible 
to participate in this plan if they are employed by Rambus for more than 20 hours per week and more than five months in a fiscal year. 
The 2006 Purchase Plan provides for six month offering periods, with a new offering period commencing on the first trading day on or 
after May 1 and November 1 of each year. Under this plan, employees may purchase stock at the lower of 85% of the beginning of the 
offering period (the enrollment date), or the end of each offering period (the purchase date). Employees generally may not purchase 
more than the number of shares having a value greater than $25,000 in any calendar year, as measured at the purchase date. 

During  the  year  ended  December 31,  2011,  the  Company  issued  271,804 shares  under  the  2006  Purchase  Plan  at  a  weighted 
average  price  of  $15.62  per  share.  During  the  year  ended  December 31,  2010,  the  Company  issued  261,088 shares  under  the  2006 
Purchase  Plan  at  a  weighted  average  price  of  $14.78  per  share.  During  the  year  ended  December 31,  2009,  the  Company  issued 
418,215 shares  under  the  2006  Purchase  Plan  at  a  weighted  average  price  of  $8.95  per  share.  As  of  December 31,  2011, 
313,964 shares remain available for issuance under the 2006 Purchase Plan.

During the years ended December 31, 2011, 2010 and 2009, Rambus granted 2,357,001, 1,921,743 and 1,487,905 stock options, 
respectively, with an estimated total grant-date fair value of $24.2 million, $24.9 million and $10.2 million, respectively. During the 
years  ended  December 31,  2011,  2010  and  2009,  Rambus  recorded  stock-based  compensation  related  to  stock  options  of 
$19.6 million, $22.6 million and $24.4 million, respectively. 

As of December 31, 2011, there was $35.8 million of total unrecognized compensation cost, net of expected forfeitures, related to 
unvested stock-based compensation arrangements granted under the stock option plans. This cost is expected to be recognized over a 
weighted-average period of 3.3 years. The total fair value of options vested for the years ended December 31, 2011, 2010 and 2009 
was $144.8 million, $137.9 million and $195.2 million, respectively.  

The  total  intrinsic  value  of  options  exercised  was  $6.2 million,  $9.1 million  and  $8.3 million  for  the  years  ended  December 31, 
2011, 2010 and 2009, respectively. Intrinsic value is the total value of exercised shares based on the price of the Company’s Common 
Stock at the time of exercise less the proceeds received from the employees to exercise the options. 

During the years ended December 31, 2011, 2010 and 2009, proceeds from employee stock option exercises totaled approximately 
$7.4 million,  $12.9 million  (of  which  $0.6 million  was  included  in  prepaid  and  other  assets  as  of  December 31,  2010  and  was 
subsequently  received  in  January  2011),  and  $16.7 million  (of  which  $0.3 million  was  included  in  prepaid  and  other  assets  as  of 
December 31, 2009 and was subsequently received in January 2010), respectively.  

Employee Stock Purchase Plans 

During the years ended December 31, 2011, 2010 and 2009, Rambus recorded stock-based compensation related to employee stock 
purchase plans of $1.7 million, $1.6 million and $1.8 million, respectively. As of December 31, 2011, there was $0.9 million of total 
unrecognized compensation cost related to share-based compensation arrangements granted under the 2006 Purchase Plan. That cost is 
expected to be recognized over four months. 

There were no tax benefits realized as a result of employee stock option exercises, stock purchase plan purchases, and vesting of 
equity  stock  and  stock  units  for  the  years  ended  December 31,  2011,  2010  and  2009  calculated  in  accordance  with  accounting  for 
share-based payments. 

Valuation Assumptions 

Rambus estimates the fair value of stock options using the Black-Scholes-Merton model (“BSM”). The BSM model determines the 
fair  value  of  stock-based  compensation  and  is  affected  by  Rambus’  stock  price  on  the  date  of  the  grant  as  well  as  assumptions 
regarding  a  number  of  highly  complex  and  subjective  variables.  These  variables  include  expected  volatility,  expected  life  of  the 
award, expected dividend rate, and expected risk-free rate of return. The assumptions for expected volatility and expected life are the 
two  assumptions  that  significantly  affect  the  grant  date  fair  value.  If  actual  results  differ  significantly  from  these  estimates,  stock-
based compensation expense and Rambus’ results of operations could be materially impacted. 

The fair value of stock awards is estimated as of the grant date using the BSM option-pricing model assuming a dividend yield of 

0% and the additional weighted-average assumptions as listed in the following tables:

Expected Stock Price Volatility:  Given the volume of market activity in its market traded options, Rambus determined that it would 
use the implied volatility of its nearest-to-the-money traded options. The Company believes that the use of implied volatility is more 
reflective of market conditions and a better indicator of expected volatility than historical volatility. If there is not sufficient volume in 
its market traded options, the Company will use an equally weighted blend of historical and implied volatility.  

Risk-free  Interest  Rate:  Rambus  bases  the  risk-free  interest  rate  used  in  the  BSM  valuation  method  on  implied  yield  currently 
available on the U.S. Treasury zero-coupon issues with an equivalent term. Where the expected terms of Rambus’ stock-based awards 
do not correspond with the terms for which interest rates are quoted, Rambus uses an approximation based on rates on the closest term 
currently available.  

Expected  Term:  The  expected  term  of  options  granted  represents  the  period  of  time  that  options  granted  are  expected  to  be 
outstanding.  The  expected  term  was  determined  based  on  historical  experience  of  similar  awards,  giving  consideration  to  the 
contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior. The expected term of 
ESPP grants is based upon the length of each respective purchase period. 

Nonvested Equity Stock and Stock Units 

The Company grants nonvested equity stock units to certain officers, employees and directors. For the year ended December 31, 
2011, the Company granted nonvested equity stock units totaling 374,838 shares under the 2006 Plan. These awards have a service 
condition, generally a service period of four years, except in the case of grants to directors, for which the service period is one year. 
The  nonvested  equity  stock  units  were  valued  at  the  date  of  grant  giving  them  a  fair  value  of  approximately  $6.7 million.  The 
Company  occasionally  grants  nonvested  equity  stock  units  to  its  employees  with  vesting  subject  to  the  achievement  of  certain 
performance conditions. During the years ended December 31, 2011 and 2010, the achievement of certain performance conditions for 
certain performance equity stock units was considered probable, and as a result, the Company recognized an insignificant amount of 
stock-based compensation expense related to these performance stock units for both years. During the year ended December 31, 2009, 
the Company did not recognize any compensation expense for any performance equity stock units since the performance conditions 
had not been met. 

For  the  years  ended  December 31,  2011,  2010,  and  2009,  the  Company  recorded  stock-based  compensation  expense  of 
approximately $6.7 million, $6.3 million and $5.4 million, respectively, related to all outstanding equity stock grants. Unrecognized 
stock-based  compensation  related  to  all  nonvested  equity  stock  grants,  net  of  an  estimate  of  forfeitures,  was  approximately 
$8.4 million at December 31, 2011. This cost is expected to be recognized over a weighted average period of 1.8 years. 

The following table reflects the activity related to nonvested equity stock and stock units for the three years ended December 31,

10.  Stockholders’ Equity and Contingently Redeemable Common Stock 

During the second quarter of 2011, the Company acquired CRI. As part of the acquisition, the Company issued approximately 6.4 
million shares of the Company’s common stock, of which approximately 161 thousand shares were used to satisfy tax withholding 
obligations for certain former CRI employees and consultants. See Note 18, “Acquisition,” for additional information regarding the 
acquisition of CRI. 

Contingently Redeemable Common Stock 

On January 19, 2010, pursuant to the terms of the Stock Purchase Agreement, Samsung purchased for cash from the Company 9.6 
million shares of the Company (the “Shares”) with certain restrictions and put rights. The issuance of the Shares by the Company to 
Samsung was made through a private transaction. The Stock Purchase Agreement provided Samsung a one-time put right, beginning 
18 months after the date of the Stock Purchase Agreement and extending to 19 months after the date of the Stock Purchase 
Agreement, to put back to the Company up to 4.8 million of the Shares at the original issue price of $20.885 per share (for an 
aggregate purchase price of up to $100.0 million). The 4.8 million shares were recorded as contingently redeemable common stock on 
the consolidated balance sheet as of December 31, 2010. 

The Stock Purchase Agreement prohibited the transfer of the Shares by Samsung for 18 months after the date of the Stock Purchase 

Agreement, subject to certain exceptions. After expiration of the transfer restriction period on July 18, 2011, the Stock Purchase 
Agreement provided that Samsung could transfer a limited number of shares on a daily basis, provided the Company with a right of 
first offer for proposed transfers above such daily limits, and, if no sale occurs to the Company under the right of first offer, allowed 
Samsung to transfer the Shares. Under the Stock Purchase Agreement, the Company also agreed that after the transfer restriction 
period, Samsung will have certain rights to register the Shares for sale under the securities laws of the United States, subject to 
customary terms and conditions. 

On July 20, 2011, the Company received notice from Samsung exercising their option to put back to the Company approximately 
4.8 million of the Shares for cash of $100.0 million. In August 2011, the Company paid $100.0 million to Samsung in exchange for 
the 4.8 million shares, which were retired. The difference between the amount recorded as contingently redeemable common stock 
and the cash paid was recorded as additional paid-in capital in the Company’s consolidated balance sheet. 

See Note 4, “Settlement Agreement with Samsung,” for further discussion. 

Share Repurchase Program 

In  October  2001,  the  Company’s  Board  of  Directors  (the  “Board”)  approved  a  share  repurchase  program  of  its  Common  Stock, 
principally to reduce the dilutive effect of employee stock options. To date, the Board has approved the authorization to repurchase up 
to  19.0 million  shares  of  the  Company’s  outstanding  Common  Stock  over  an  undefined  period  of  time.  On  February  25,  2010,  the 
Board  approved  a  new  share  repurchase  program  authorizing  the  repurchase  of  up  to  an  additional  12.5  million  shares. Share 
repurchases under the program may be made through open market, established plan or privately negotiated transactions in accordance 
with  all  applicable  securities  laws,  rules,  and  regulations. There  is  no  expiration  date  applicable  to  the  program. The  new  share 
repurchase program replaces the program authorized in October 2001.  

On  August  19,  2010,  the  Company  entered  into  a  share  repurchase  agreement  (the  “Share  Repurchase  Agreement”)  with  J.P. 
Morgan  Securities  Inc.,  as  agent  for  JPMorgan  Chase  Bank,  National  Association,  London  Branch  (“JP  Morgan”)  to  repurchase 
approximately $90.0 million of its Common Stock, as part of its share repurchase program. Under the Share Repurchase Agreement, 
the Company pre-paid to J.P. Morgan the $90.0 million purchase price in the third quarter of 2010 for the Common Stock and J.P. 
Morgan delivered to the Company approximately 4.8 million shares of Common Stock at an average price of $18.88 at the completion 
of the Share Repurchase Agreement in December 2010. 

89 

 
 
 
 
 
 
 
 
 
 
 
 
 
For  the  year  ended  December  31,  2011,  the  Company  did  not  repurchase  any  shares  of  its  Common  Stock  under  its  share 
repurchase  program.  For  the  year  ended  December  31,  2010,  the  Company  repurchased  approximately  9.5  million  shares  of  its 
Common Stock with an aggregate price of approximately $195.1 million, including the price paid pursuant to the Share Repurchase 
Agreement. For the year ended December 31, 2009, the Company did not repurchase any shares of its Common Stock under its share 
repurchase program. As of December 31, 2011, the Company had repurchased a cumulative total of approximately 26.3 million shares 
of its Common Stock with an aggregate price of approximately $428.9 million since the commencement of the program in 2001. As of 
December  31,  2011,  there  remained  an  outstanding  authorization  to  repurchase  approximately  5.2 million  shares  of  the  Company’s 
outstanding Common Stock. 

The  Company  records  stock repurchases  as  a  reduction  to  stockholders’  equity.  The  Company  records  a  portion  of the  purchase 
price of the repurchased shares as an increase to accumulated deficit when the price of the shares repurchased exceeds the average 
original proceeds per share received from the issuance of Common Stock. During the year ended December 31, 2011, the Company 
did not repurchase any Common Stock. During the year ended December 31, 2010, the cumulative price of the shares repurchased 
exceeded  the proceeds  received from  the  issuance  of  the  same  number  of  shares.  The  excess  of  $163.6 million  was  recorded  as  an 
increase to accumulated deficit for the year ended December 31, 2010. During the year ended December 31, 2009, the Company did 
not repurchase any Common Stock.  

11.  Benefit Plans 

Rambus has a 401(k) Profit Sharing Plan (the “401(k) Plan”) qualified under Section 401(k) of the Internal Revenue Code of 1986. 
Each  eligible  employee  may  elect  to  contribute  up  to  60%  of  the  employee’s  annual  compensation  to  the  401(k)  Plan,  up  to  the 
Internal Revenue Service limit. Rambus, at the discretion of its Board of Directors, may match employee contributions to the 401(k) 
Plan. The Company matches 50% of eligible employee’s contribution, up to the first 6% of an eligible employee’s qualified earnings. 
For the years ended December 31, 2011, 2010 and 2009, Rambus made matching contributions totaling approximately $1.6 million, 
$1.2 million and $1.1 million, respectively.

As of December 31, 2011, the Company’s consolidated balance sheet included net deferred tax assets, before valuation allowance, 
of approximately $149.3 million, which consists of net operating loss carryovers, tax credit carryovers, amortization, employee stock-
based  compensation  expenses  and  certain  liabilities,  partially  reduced  by  deferred  tax  liabilities  associated  with  convertible  debt 
instruments. For the year ended December 31, 2011, the Company’s valuation allowance increased to $141.0 million as a result of an 
increase in deferred tax assets before valuation from taking a foreign tax credit instead of a deduction on withholding taxes as well as 
various timing items related to other liabilities and reserves. Management periodically evaluates the realizability of the Company’s net 
deferred tax assets based on all available evidence, both positive and negative. The realization of net deferred tax assets is dependent 
on  the  Company’s  ability  to  generate  sufficient  future  taxable  income  during  periods  prior  to  the  expiration  of  tax  statutes  to  fully 
utilize these assets.  

The Company weighed both positive and negative evidence and determined that there is a continued need for a valuation allowance 
due  to  projected  future  losses,  which  the  Company  considered  significant  negative  evidence.  Though  considered positive  evidence, 
potential income from currently unsigned favorable patent and related settlement litigation were not included in the determination for 
the valuation allowance due to the Company’s inability to reliably estimate the probability, timing and amounts of such settlements. 
Even though the Company is no longer in a cumulative loss position, the projection of significant future losses is a negative factor that 
outweighs the positive factors leading to a conclusion that a release of the valuation allowance is not yet appropriate. If any settlement 
income is realized, the Company will reassess its position on maintaining the valuation allowance.  

As  of  December 31,  2011,  Rambus  has  state  net  operating  loss  carryforwards  for  income  tax  purposes  of  $245.9 million  which 
begin to expire in 2018. As of December 31, 2011, Rambus has federal research and development tax credit carryforwards for income 
tax purposes of $23.3 million and state research and development tax credit carryforwards of $4.8 million, net of federal benefit. The 
federal  research  and  development  tax  credit  carryforwards  begin  to  expire  in  2012  and  the  state  tax  credit  can  be  carried  forward 
indefinitely.

In  the  event  of  a  change  in  ownership,  as  defined  under  federal  and  state  tax  laws,  Rambus’  net  operating  loss  and  tax  credit 
carryforwards could be subject to annual limitations. The annual limitations could result in the expiration of the net operating loss and 
tax credit carryforwards prior to utilization. 

Tax  attributes  related  to  stock  option  windfall  deductions  should  not  be  recorded  until  they  result  in  a  reduction  of  cash  taxes 
payable. The Company’s unrealized excess tax benefits from stock option deductions excluded from the federal and state tax attributes 
as of December 31, 2011 were $93.5 million and $99.2 million, respectively. The excess tax benefits will be recorded to additional 
paid-in capital when they reduce cash taxes payable. 

As  of  December  31,  2011,  the  Company  had  $16.6  million  of  unrecognized  tax  benefits  including  $7.0  million  recorded  as  a 
reduction of long-term deferred tax assets and $9.6 million recorded in long term income taxes payable. If recognized, $2.6 million 
would be recorded as an income tax benefit in the consolidated statements of operations. As of December 31, 2010, the Company had 
$11.8 million of unrecognized tax benefits including $7.2 million recorded as a reduction of long-term deferred tax assets and $4.6 
million recorded in long term  income taxes payable. If recognized, $2.8 million would be recorded as an income tax benefit in the 
consolidated statements of operations.  

At  December 31,  2011,  no  deferred  taxes  have  been  provided  on  undistributed  earnings  of  approximately  $6.1 million  from  the 
Company’s  international  subsidiaries  since  these  earnings  have  been,  and  under  current  plans  will  continue  to  be,  permanently 
reinvested outside the United States. The Company’s operations in India was under a tax holiday which expired in 2011. 

A reconciliation of the beginning and ending amounts of unrecognized income tax benefits for the years ended December 31, 2011,

Rambus recognizes interest and penalties related to uncertain tax positions as a component of the income tax provision (benefit). At 

December 31, 2011 and 2010, an insignificant amount of interest and penalties are included in long-term income taxes payable. 

Rambus files U.S. federal income tax returns as well as income tax returns in various states and foreign jurisdictions. The Company 
is subject to examination by the IRS for tax years ended 2008 through 2010. The Company is also subject to examination by the State 
of  California  for  tax  years  ended  2007  through  2010.  In  addition,  any  R&D  credit  carryforward  or  net  operating  loss  carryforward 
generated in prior years and utilized in these or future years may also be subject to examination by the IRS and the State of California. 
The Company is also subject to examination in various other foreign jurisdictions, including India, for various periods. Although it is 
possible  that  some  of  the  unrecognized  tax  benefits  could  be  settled  within  the  next  12  months,  the  Company  cannot  reasonably 
estimate the outcome at this time. 

13.  Earnings (Loss) Per Share 

Basic earnings (loss) per share is calculated by dividing the net income (loss) by the weighted average number of common shares 
outstanding during the period. Diluted earnings (loss) per share is calculated by dividing the earnings (loss) by the weighted average 
number of common shares and potentially dilutive securities outstanding during the period. Potentially dilutive common shares consist 
of incremental common shares issuable upon exercise of stock options, employee stock purchases, restricted stock and restricted stock 
units  and  shares  issuable  upon  the  conversion  of  convertible  notes.  The  dilutive  effect  of  outstanding  shares  is  reflected  in  diluted 
earnings per share by application of the treasury stock method. This method includes consideration of the amounts to be paid by the

employees, the amount of excess tax benefits that would be recognized in equity if the instrument was exercised and the amount of 
unrecognized  stock-based  compensation  related  to  future  services.  No  potential  dilutive  common  shares  are  included  in  the 
computation  of  any  diluted  per  share  amount  when  a  net  loss  is  reported.  As  discussed  in  Note  4,  “Settlement  Agreement  with 
Samsung,” the Company reported approximately 4.8 million shares issued to Samsung as contingently redeemable common stock due 
to the contractual put rights associated with those shares. As such, the Company used the two-class method for reporting earnings per 
share for those periods where the contingently redeemable common stock were outstanding (during 2010 until August 2011).

For  the  years  ended  December 31,  2011,  2010  and  2009,  options  to  purchase  approximately  12.0  million,  6.4  million  and 
11.0 million shares, respectively, were excluded from the calculation because they were anti-dilutive after considering proceeds from 
exercise,  taxes  and  related  unrecognized  stock-based  compensation  expense.  For  the  years  ended  December 31,  2011  and  2009,  an 
additional 4.1 million and 1.4 million potentially dilutive shares, respectively, have been excluded from the weighted average dilutive 
shares because there was a net loss for the period.

The Company evaluates the performance of its segments based on segment direct operating income (loss). Segment direct operating 
income (loss) does not include the allocation of any corporate support functions (including human resources, facilities, legal, finance, 
information  technology,  corporate  development,  general  administration,  corporate  licensing  and  marketing  expenses,  advanced 
technology development, and cost of restatement) to the segments. Additionally, certain expenses are not allocated to the operating 
segments as they are managed at the corporate level and they are not considered in evaluating the segments’ operating performance. 
For  the  year  ended  December  31,  2011,  such  unallocated  corporate  level  expenses  include  stock-based  compensation  expenses, 
depreciation and amortization expenses, and certain bonus and acquisition expenses. The “Reconciling Items” category includes these 
unallocated corporate support function expenses as well as corporate level expenses. The presentation of the 2010 segment data has 
been updated accordingly to conform with the 2011 segment direct operating income (loss) definition.

5% Convertible Senior Notes due 2014. On June 29, 2009, the Company issued $150.0 million aggregate principal amount of 5% 
convertible senior notes due June 15, 2014. As of the date of issuance, the Company determined that the liability component of the 
2014  Notes  was  approximately  $92.4  million  and  the  equity  component  was  approximately  $57.6  million.  On  July  10,  2009,  an 
additional $22.5 million of the 2014 Notes were issued as a result of the underwriters exercising their overallotment option. As of the 
date  of  issuance  of  the  $22.5  million  2014  Notes,  the  Company  determined  that  the  liability  component  was  approximately  $14.3 
million  and  the  equity  component  was  approximately  $8.2  million.  The  unamortized  discount  related  to  the  2014  Notes  is  being 
amortized to interest expense using the effective interest method over five years through June 2014. 

The Company will pay cash interest at an annual rate of 5% of the principal amount at issuance, payable semi-annually in arrears on 
June 15 and December 15 of each year, beginning on December 15, 2009. During 2011, the Company paid approximately $8.6 million 
of interest related to the 2014 Notes. During 2010, the Company paid approximately $8.6 million of interest related to the 2014 Notes. 
In the fourth quarter of 2009, the Company paid approximately $4.0 million of interest related to the 2014 Notes. Issuance costs were 
approximately $5.1 million of which $3.2 million is related to the liability portion, which is being amortized to interest expense over 
five years (the expected term of the debt), and $1.9 million is related to the equity portion. The 2014 Notes are the Company’s general 
unsecured obligation, ranking equal in right of payment to all of the Company’s existing and future senior indebtedness and are senior 
in right of payment to any of the Company’s future indebtedness that is expressly subordinated to the 2014 Notes. 

The  2014  Notes  are  convertible  into  shares  of  the  Company’s  Common  Stock  at  an  initial  conversion  rate  of  51.8  shares  of 
Common Stock per $1,000 principal amount of 2014 Notes. This is equivalent to an initial conversion price of approximately $19.31 
per share of common stock. Holders may surrender their 2014 Notes for conversion prior to March 15, 2014 only under the following 
circumstances: (i) during any calendar quarter beginning after the calendar quarter ending September 30, 2009, and only during such 
calendar quarter, if the closing sale price of the Common Stock for 20 or more trading days in the period of 30 consecutive trading 
days ending on the last trading day of the immediately preceding calendar quarter exceeds 130% of the conversion price in effect on 
the last trading day of the immediately preceding calendar quarter, (ii) during the five business day period after any 10 consecutive 
trading day period in which the trading price per $1,000 principal amount of 2014 Notes for each trading day of such 10 consecutive 
trading  day  period  was  less  than  98%  of  the  product  of  the  closing  sale  price  of  the  Common  Stock  for  such  trading  day  and  the 
applicable  conversion  rate,  (iii)  upon  the  occurrence  of  specified  distributions  to  holders  of  the  Common  Stock,  (iv)  upon  a 

95 

 
 
 
 
 
 
 
 
 
 
 
  
 
 
 
 
fundamental change of the Company as specified in the Indenture governing the 2014 Notes, or (v) if the Company calls any or all of 
the 2014 Notes for redemption, at any time prior to the close of business on the business day immediately preceding the redemption 
date. On and after March 15, 2014, holders may convert their 2014 Notes at any time until the close of business on the third business 
day prior to the maturity date, regardless of the foregoing circumstances. 

Upon conversion of the 2014 Notes, the Company will pay (i) cash equal to the lesser of the aggregate principal amount and the 
conversion  value  of  the  2014  Notes  and  (ii)  shares  of  the  Company’s  Common  Stock  for  the  remainder,  if  any,  of  the  Company’s 
conversion obligation, in each case based on a daily conversion value calculated on a proportionate basis for each trading day in the 20 
trading day conversion reference period as further specified in the Indenture. 

The  Company  may  not  redeem  the  2014  Notes  at  its  option  prior  to  June  15,  2012.  At  any  time  on  or  after  June  15,  2012,  the 
Company will have the right, at its option, to redeem the 2014 Notes in whole or in part for cash in an amount equal to 100% of the 
principal amount of the 2014 Notes to be redeemed, together with accrued and unpaid interest, if any, if the closing sale price of the 
Common  Stock  for  at  least  20  of  the  30  consecutive  trading  days  immediately  prior  to  any  date  the  Company  gives  a  notice  of 
redemption is greater than 130% of the conversion price on the date of such notice. 

Upon the occurrence of a fundamental change, holders may require the Company to repurchase some or all of their 2014 Notes for 
cash at a price equal to 100% of the principal amount of the 2014 Notes being repurchased, plus accrued and unpaid interest, if any. In 
addition, upon the occurrence of certain fundamental changes, as that term is defined in the Indenture, the Company will, in certain 
circumstances,  increase  the  conversion  rate  for  2014  Notes  converted  in  connection  with  such  fundamental  changes  by  a  specified 
number of shares of Common Stock, not to exceed 15.5401 per $1,000 principal amount of the 2014 Notes. 

The following events are considered “Events of Default” under the Indenture which may result in the acceleration of the maturity of 

the 2014 Notes: 

(1)  default in the payment when due of any principal of any of the 2014 Notes at maturity, upon redemption or upon exercise of a 

repurchase right or otherwise; 

(2)  default  in  the  payment  of  any  interest,  including  additional  interest,  if  any,  on  any  of  the  2014  Notes,  when  the  interest 

becomes due and payable, and continuance of such default for a period of 30 days; 

(3) 

the Company’s failure to deliver cash or cash and shares of Common Stock (including any additional shares deliverable as a 
result  of  a  conversion  in  connection  with  a  make-whole  fundamental  change)  when  required  to  be  delivered  upon  the 
conversion of any 2014 Note; 

(4)  default  in  the  Company’s  obligation  to  provide  notice  of  the  occurrence  of  a  fundamental  change  when  required  by  the 

Indenture; 

(5) 

(6) 

the  Company’s  failure  to  comply  with  any  of  its  other  agreements  in  the  2014  Notes  or  the  Indenture  (other  than  those 
referred to in clauses (1) through (4) above) for 60 days after the Company’s receipt of written notice to the Company of such 
default from the trustee or to the Company and the trustee of such default from holders of not less than 25% in aggregate 
principal amount of the 2014 Notes then outstanding; 

the  Company’s  failure  to  pay  when  due  the  principal  of,  or  acceleration  of,  any  indebtedness  for  money  borrowed  by  the 
Company or any of its subsidiaries in excess of $30,000,000 principal amount, if such indebtedness is not discharged, or such 
acceleration is not annulled, by the end of a period of ten days after written notice to the Company by the trustee or to the 
Company and the trustee by the holders of at least 25% in aggregate principal amount of the 2014 Notes then outstanding; 
and 

(7)  certain  events  of  bankruptcy,  insolvency  or  reorganization  relating  to  the  Company  or  any  of  its  material  subsidiaries  (as 

defined in the Indenture). 

96 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
If  an  event  of  default,  other  than  an  event  of  default  in  clause  (7)  above  with  respect  to  the  Company  occurs  and  is  continuing, 
either  the  trustee  or  the  holders  of  at  least  25%  in  aggregate  principal  amount  of  the  2014  Notes  then  outstanding  may  declare  the 
principal amount of, and accrued and unpaid interest, including additional interest, if any, on the 2014 Notes then outstanding to be 
immediately due and payable. If an event of default described in clause (7) above occurs with respect to the Company the principal 
amount  of  and  accrued  and  unpaid  interest,  including  additional  interest,  if  any,  on  the  2014  Notes  will  automatically  become 
immediately due and payable. 

Zero Coupon Convertible Senior Notes due 2010. On February 1, 2005, the Company issued $300.0 million aggregate principal 
amount  of  zero  coupon  convertible  senior  notes  due  February  1,  2010  (the  “2010  Notes”)  to  Credit  Suisse  First  Boston  LLC  and 
Deutsche Bank Securities as initial purchasers who then sold the 2010 Notes to institutional investors.  

The  2010 Notes  were unsecured  senior obligations, ranking  equally in  right  of  payment  with  all  of Rambus’  existing  and  future 
unsecured senior indebtedness, and senior in right of payment to any future indebtedness that is expressly subordinated to the 2010 
Notes. 

The  2010  Notes  were  convertible  at  any  time  prior  to  the  close  of  business  on  the  maturity  date  into,  in  respect  of  each  $1,000 

principal of the 2010 Notes: 

•  cash in an amount equal to the lesser of  

(1)  the principal amount of each note to be converted and  

(2)  the “conversion value,” which is equal to (a) the applicable conversion rate, multiplied by (b) the applicable stock price, as 

defined. 

• 

if the conversion value is greater than the principal amount of each note, a number of shares of Rambus Common Stock (the 
“net  shares”)  equal  to  the  sum  of  the  daily  share  amounts,  calculated  as  defined.  However,  in  lieu  of  delivering  net  shares, 
Rambus, at its option, may deliver cash, or a combination of cash and shares of its Common Stock, with a value equal to the 
net shares amount. 

The initial conversion price was $26.84 per share of Common Stock (which represented an initial conversion rate of 37.2585 shares 
of  Rambus  Common  Stock  per  $1,000  principal  amount  of  the  2010  Notes).  The  initial  conversion  price  was  subject  to  certain 
adjustments, as specified in the indenture governing the 2010 Notes. 

On February 1, 2010, the Company paid upon maturity the remaining $137.0 million in face value of the 2010 Notes.  

Additional paid-in capital at December 31, 2011 and December 31, 2010 includes $63.9 million related to the equity component of 

the 2014 Notes.  

As of December 31, 2011, none of the conversion conditions were met related to the 2014 Notes. Therefore, the classification of the 

entire equity component for the 2014 Notes in permanent equity is appropriate as of December 31, 2011. 

Interest expense related to the notes for the years ended December 31, 2011, 2010 and 2009 was as follows: 

2014 Notes coupon interest at a rate of 5% 
2014 Notes amortization of discount at an additional effective interest rate of 11.7%
2010 Notes amortization of discount at an effective interest rate of 8.4%

In  2010,  the  Company  adjusted  its  interest  expense  on  convertible  notes  by  approximately  $0.7  million  due  to  the  incorrect 
amortization of the non-cash debt discount related to the 2014 Notes. The Company concluded that the correction was not material to 
the previous or present periods.  

16.  Litigation and Asserted Claims 

Hynix Litigation 

U.S District Court of the Northern District of California 

On August 29, 2000, Hynix (formerly Hyundai) and various subsidiaries filed suit against Rambus in the U.S. District Court for 
the  Northern  District  of  California.  The  complaint,  as  amended  and  narrowed  through  motion  practice,  asserts  claims  for  fraud, 
violations  of  federal  antitrust  laws  and  deceptive  practices  in  connection  with  Rambus’  participation  in  a  standards  setting 
organization  called  JEDEC,  and  seeks  a  declaratory  judgment  that  the  Rambus  patents-in-suit  are  unenforceable,  invalid  and  not 
infringed by Hynix, compensatory and punitive damages, and attorneys’ fees. Rambus denied Hynix’s claims and filed counterclaims 
for patent infringement against Hynix. 

The case was divided into three phases. In the first phase, Hynix tried its unclean hands defense beginning on October 17, 2005 
and concluding on November 1, 2005. In its January 4, 2006 Findings of Fact and Conclusions of Law, the court held that Hynix’s 
unclean hands defense failed. Among other things, the court found that Rambus did not adopt its document retention policy in bad 
faith, did not engage in unlawful spoliation of evidence, and that while Rambus disposed of some relevant documents pursuant to its 
document retention policy, Hynix was not prejudiced by the destruction of Rambus documents. On January 19, 2009, Hynix filed a 
motion  for  reconsideration  of  the  court’s  unclean  hands  order  and  for  summary  judgment  on  the  ground  that  the  decision  by  the 
Delaware  court  in  the  pending  Micron-Rambus  litigation  (described  below)  should  be  given  preclusive  effect.  In  its  motion  Hynix 
requested  alternatively  that  the  court’s  unclean  hands  order  be  certified  for  appeal  and  that  the  remainder  of  the  case  be  stayed. 
Rambus  filed  an  opposition  to  Hynix’s  motion  on  January 26,  2009,  and  a  hearing  was  held  on  January 30,  2009.  On  February 3, 
2009, the court denied Hynix’s motions and restated its conclusions that Rambus had not anticipated litigation until late 1999 and that 
Hynix had not demonstrated any prejudice from any alleged destruction of evidence. 

The second phase of the Hynix-Rambus trial — on patent infringement, validity and damages — began on March 15, 2006, and 
was  submitted  to  the  jury  on  April 13,  2006.  On  April 24,  2006,  the  jury  returned  a  verdict  in  favor  of  Rambus  on  all  issues  and 
awarded Rambus a total of approximately $307 million in damages, excluding prejudgment interest. Specifically, the jury found that 
each of the ten selected patent claims was supported by the written description, and was not anticipated or rendered obvious by prior 
art; therefore, none of the patent claims was invalid. The jury also found that Hynix infringed all eight of the patent claims for which 
the jury was asked to determine infringement; the court had previously determined on summary judgment that Hynix infringed the 
other two claims at issue in the trial. On July 14, 2006, the court granted Hynix’s motion for a new trial on the issue of damages unless 
Rambus  agreed  to  a  reduction  of  the  total  jury  award  to  approximately  $134 million.  The  court  found  that  the  record  supported  a 
maximum royalty rate of 1% for SDR SDRAM and 4.25% for DDR SDRAM, which the court applied to the stipulated U.S. sales of 
infringing  Hynix  products  through  December 31,  2005.  On  July 27,  2006,  Rambus  elected  remittitur  of  the  jury’s  award  to 
approximately  $134 million.  On  August 30,  2006,  the  court  awarded  Rambus  prejudgment  interest  for  the  period  June 23,  2000 
through December 31, 2005. Hynix filed a motion on July 7, 2008 to reduce the amount of remitted damages and any supplemental 
damages that the court may award, as well as to limit the products that could be affected by any injunction that the court may grant, on 
the grounds of patent exhaustion. Following a hearing on August 29, 2008, the court denied Hynix’s motion. In separate orders issued 
December 2, 2008, January 16, 2009, and January 27, 2009, the court denied Hynix’s post-trial motions for judgment as a matter of 
law and new trial on infringement and validity. 

On June 24, 2008, the court heard oral argument on Rambus’ motion to supplement the damages award and for equitable relief 
related to Hynix’s infringement of Rambus patents. On February 23, 2009, the court issued an order (1) granting Rambus’ motion for 
supplemental damages and prejudgment interest for the period after December 31, 2005, at the same rates ordered for the prior period; 
(2) denying Rambus’ motion for an injunction; and (3) ordering the parties to begin negotiations regarding the terms of a compulsory 
license regarding Hynix’s continued manufacture, use, and sale of infringing devices.

The  third  phase  of  the  Hynix-Rambus  trial  involved  Hynix’s  affirmative  JEDEC-related  antitrust  and  fraud  allegations  against 
Rambus.  On  April 24,  2007,  the  court  ordered  a  coordinated  trial  of  certain  common  JEDEC-related  claims  alleged  by  the 
manufacturer parties (i.e., Hynix, Micron, Nanya and Samsung) and defenses asserted by Rambus in Hynix v Rambus, Case No. C 00-
20905  RMW,  and  three  other  cases  then  pending  before  the  same  court  (Rambus  Inc. v.  Samsung  Electronics  Co.  Ltd.  et  al.,  Case 
No. 05-02298 RMW, Rambus Inc. v. Hynix Semiconductor Inc., et al., Case No. 05-00334, and Rambus Inc. v. Micron Technology, 
Inc., et al., Case No. C 06-00244 RMW, each described in further detail below). On December 14, 2007, the court excused Samsung 
from  the coordinated trial based on Samsung’s agreement to certain conditions, including trial of its claims against Rambus by the 
court within six months following the conclusion of the coordinated trial. The coordinated trial involving Rambus, Hynix, Micron and 
Nanya began on January 29, 2008, and was submitted to the jury on March 25, 2008. On March 26, 2008, the jury returned a verdict 
in favor of Rambus and against Hynix, Micron, and Nanya on each of their claims. Specifically, the jury found that Hynix, Micron, 
and Nanya failed to meet their burden of proving that: (1) Rambus engaged in anticompetitive conduct; (2) Rambus made important 
representations that it did not have any intellectual property pertaining to the work of JEDEC and intended or reasonably expected that 
the representations would be heard by or repeated to others including Hynix, Micron or Nanya; (3) Rambus uttered deceptive half-
truths about its intellectual property coverage or potential coverage of products compliant with synchronous DRAM standards then 
being considered by JEDEC by disclosing some facts but failing to disclose other important facts; or (4) JEDEC members shared a 
clearly defined expectation that members would disclose relevant knowledge they had about patent applications or the intent to file 
patent applications on technology being considered for adoption as a JEDEC standard. Hynix, Micron, and Nanya filed motions for a 
new trial and for judgment on certain of their equitable claims and defenses. A hearing on those motions was held on May 1, 2008. A 
further hearing on the equitable claims and defenses was held on May 27, 2008. On July 24, 2008, the court issued an order denying 
Hynix, Micron, and Nanya’s motions for new trial.  

On March 3, 2009, the court issued an order rejecting Hynix, Micron, and Nanya’s equitable claims and defenses that had been 
tried during the coordinated trial. The court concluded (among other things) that (1) Rambus did not have an obligation to disclose 
pending or anticipated patent applications and had sound reasons for not doing so; (2) the evidence supported the jury’s finding that 
JEDEC members did not share a clearly defined expectation that members would disclose relevant knowledge they had about patent 
applications or the intent to file patent applications on technology being considered for adoption as a JEDEC standard; (3) the written 
JEDEC  disclosure  policies  did  not  clearly  require  members  to  disclose  information  about  patent  applications  and  the  intent  to  file 
patent applications in the future; (4) there was no clearly understood or legally enforceable agreement of JEDEC members to disclose 
information about patent applications or the intent to seek patents relevant to standards being discussed at JEDEC; (5) during the time 
Rambus attended JEDEC meetings, Rambus did not have any patent application pending that covered a JEDEC standard, and none of 
the patents in suit was applied for until well after Rambus resigned from JEDEC; (6) Rambus’s conduct at JEDEC did not constitute 
an  estoppel  or  waiver  of  its  rights  to  enforce  its  patents;  (7) Hynix,  Micron,  and  Nanya  failed  to  carry  their  burden  to  prove  their 
asserted waiver and estoppel defenses not directly based on Rambus’s conduct at JEDEC; (8) the evidence did not support a finding of 
any material misrepresentation, half truths or fraudulent concealment by Rambus related to JEDEC upon which Nanya relied; (9) the 
manufacturers failed to establish that Rambus violated unfair competition law by its conduct before JEDEC; (10) the evidence related 
to Rambus’s patent prosecution did not establish that Rambus unduly delayed in prosecuting the claims in suit; (11) Rambus did not 
unreasonably  delay  bringing  its  patent  infringement  claims;  and  (12) there  is  no  basis  for  any  unclean  hands  defense  or 
unenforceability claim arising from Rambus’s conduct. 

On  March  10,  2009,  the  court  entered  final  judgment  against  Hynix  in  the  amount  of  approximately  $397  million  as  follows: 
approximately $134 million for infringement through December 31, 2005; approximately $215 million for infringement from January 
1, 2006 through January 31, 2009; and approximately $48 million in pre-judgment interest (with post-judgment interest to accrue at 
the statutory rate). The judgment ordered Hynix to pay Rambus royalties on net sales for U.S. infringement after January 31, 2009 and 
before April 18, 2010 of 1% for SDR SDRAM and 4.25% for DDR DDR2, DDR3, GDDR, GDDR2 and GDDR3 SDRAM memory 
devices. On May 14, 2009, the court granted in part Hynix’s motion under Rule 62 seeking relief from the requirement that it post a 
full  supersedeas  bond  and  ordered  that  execution  of  the  judgment  be  stayed  on  the  condition  that,  within  45  days,  Hynix  post  a 
supersedeas bond in the amount of $250 million and provide Rambus with documentation establishing a lien in Rambus’s favor on 
property owned by Hynix in Korea in the amount of the judgment not covered by the supersedeas bond. The court also ordered that 
Hynix pay the ongoing royalties set forth in the final judgment into an escrow account. Hynix posted the $250 million supersedeas 
bond on  June 26, 2009. On September  17,  2010,  the  court  granted  Rambus’s  motion  for reconsideration of  the portion  of  its  order 
allowing Hynix to establish a lien in lieu of posting a bond for a portion of the judgment. On October 18, 2010, Hynix posted a bond 
in  the  full  amount  of  the  judgment  plus  accrued  post-judgment  interest  in  the  total  amount  of  $401.2  million.  Hynix  has  deposited 
amounts into the escrow account pursuant to the court’s order regarding ongoing royalties. The escrowed funds will be released only 

99 

 
 
 
 
upon agreement of the parties or further court order in accordance with the terms and conditions set forth in the escrow arrangement. 
On  March  8,  2010,  the  court  awarded  costs  to  Rambus  in  the  amount  of  approximately  $0.76  million.  That  amount  plus  accrued 
interest has been deposited by Hynix into the same escrow account into which ongoing royalties have been deposited.  

On April 6, 2009, Hynix filed its notice of appeal. On April 17, 2009, Rambus filed its notice of cross appeal. On August 31, 2009, 
Hynix filed its opening brief. On December 7, 2009, Rambus filed its answering and opening cross-appeal brief. Hynix’s reply and 
answering brief was filed February 16, 2010, and Rambus’s reply was filed February 23, 2010. Oral argument was coordinated with 
the  appeal  in  the  Micron  Delaware  case  (discussed  below)  and  held  on  April  5,  2010.  Oral  argument  was  reheard  by  an  expanded 
panel of five judges on October 6, 2010. On May 13, 2011, the Federal Circuit issued its opinion (1) concluding that the district court 
erred in applying too narrow a standard of reasonable foreseeability and vacating the district court’s findings of fact and conclusions 
of law regarding spoliation; (2) affirming the district court’s decisions on waiver and estoppel; (3) affirming the district court’s claim 
construction order; (4) affirming the district court’s order denying Hynix’s motion for judgment as a matter of law or for a new trial on 
the  basis  of  written  description;  (5) affirming  the  district  court’s  order  denying  Hynix’s  motion  for  a  new  trial  on  the  basis  of 
obviousness; and (6) affirming the district court’s grant of Hynix’s motion for summary judgment for the claims at issue in Rambus’s 
cross-appeal.  The  Federal  Circuit  vacated  the  district  court’s  final  judgment  and  remanded  the  case  to  the  district  court  for  further 
proceedings consistent with the Federal Circuit’s opinions in the Micron and Hynix cases. On June 27, 2011, Rambus filed a petition 
requesting that the Federal Circuit rehear the Hynix appeal if the Federal Circuit accepts the petition for rehearing Rambus filed in the 
Micron  case.  On  June  27,  2011,  Hynix  filed  a  petition  for  rehearing  and  rehearing  en  banc  with  respect  to  the  issues  of  equitable 
estoppel, implied waiver, and claim construction. On July 29, 2011, the Federal Circuit denied the parties’ petitions. On October 27, 
2011,  Hynix  filed  a  petition  seeking  review  of  the  Federal  Circuit  decision  by  the  United  States  Supreme  Court.  On  February  21, 
2012, the United States Supreme Court denied Hynix’s petition. 

On  remand,  the  parties  filed briefs on  issues  related  to unclean hands,  costs  awarded  to Hynix by  the  Federal  Circuit,  the  bond 
Hynix posted in the amount of the now-vacated judgment, and the escrowed funds. A hearing on these issues was held on December 
16, 2011. In an order dated January 11, 2012, the court released Hynix’s obligation to maintain a supersedeas bond, denied Hynix’s 
request  to  lift  Hynix’s  obligations  with  respect  to  escrowed  funds,  and  taxed  costs  against  Rambus  for  fees  Hynix  incurred  with 
respect to filing, transcripts, and bond premiums (but not other security expenses related to acquiring the bond). The exact amount of 
the costs taxed against Rambus will not be known until Hynix files a supplement to its costs bill indicating the final amount of the 
bond premiums, but Rambus has taken an accrual of $8.3 million. No decision on unclean hands has issued to date.  

Micron Litigation 

U.S District Court in Delaware: Case No. 00-792-SLR 

On  August 28,  2000,  Micron  filed  suit  against  Rambus  in  the  U.S.  District  Court  for  Delaware.  The  suit  asserts  violations  of 
federal antitrust laws, deceptive trade practices, breach of contract, fraud and negligent misrepresentation in connection with Rambus’ 
participation in JEDEC. Micron seeks a declaration of monopolization by Rambus, compensatory and punitive damages, attorneys’ 
fees, a declaratory judgment that eight Rambus patents are invalid and not infringed, and the award to Micron of a royalty-free license 
to  the  Rambus  patents.  Rambus  has  filed  an  answer  and  counterclaims  disputing  Micron’s  claims  and  asserting  infringement  by 
Micron of 12 U.S. patents. 

This  case  has  been  divided  into  three  phases  in  the  same  general  order  as  in  the  Hynix  00-20905  action:  (1) unclean  hands; 
(2) patent infringement; and (3) antitrust, equitable estoppel, and other JEDEC-related issues. A bench trial on Micron’s unclean hands 
defense began on November 8, 2007 and concluded on November 15, 2007. The court ordered post-trial briefing on the issue of when 
Rambus became obligated to preserve documents because it anticipated litigation. A hearing on that issue was held on May 20, 2008. 
The court ordered further post-trial briefing on the remaining issues from the unclean hands trial, and a hearing on those issues was 
held on September 19, 2008. 

On  January 9,  2009,  the  court  issued  an  opinion  in  which  it  determined  that  Rambus  had  engaged  in  spoliation  of  evidence  by 
failing to suspend general implementation of a document retention policy after the point at which the court determined that Rambus 
should  have  known  litigation  was  reasonably  foreseeable.  The  court  issued  an  accompanying  order  declaring  the  12  patents  in  suit 
unenforceable against Micron (the “Delaware Order”). On February 9, 2009, the court stayed all other proceedings pending appeal of 
the  Delaware  Order.  On  February 10,  2009,  judgment  was  entered  against  Rambus  and  in  favor  of  Micron  on  Rambus’  patent 

100 

 
 
 
 
 
 
 
 
 
infringement claims and Micron’s corresponding claims for declaratory relief. On March 11, 2009, Rambus filed its notice of appeal. 
Rambus filed its opening brief on July 2, 2009. On August 28, 2009, Micron filed its answering brief. On October 14, 2009, Rambus 
filed its reply brief. Oral argument was coordinated with the appeal in the Hynix case (discussed above) and held on April 5, 2010. 
Oral argument was reheard by an expanded panel of five judges on October 6, 2010. On May 13, 2011, the Federal Circuit issued its 
opinion affirming the district court’s determination that Rambus spoliated documents, vacating the district court’s dismissal sanction 
(including  the  district  court’s  determination  of  bad  faith  and  prejudice),  and  remanding  the  case  to  the  district  court  for  further 
consideration consistent with its opinion. On June 27, 2011, Rambus filed a petition for rehearing and rehearing en banc with respect 
to the issues of spoliation, bad faith, and prejudice. On July 29, 2011, the Federal Circuit denied Rambus’s petition.  

On remand, the parties filed simultaneous briefs on November 9 and December 21, 2011, on the unclean hands-related issues of 

bad faith, prejudice, and sanction. A hearing on these issues was held on January 26, 2012. No decision has issued to date.  

U.S. District Court of the Northern District of California 

On January 13, 2006, Rambus filed suit against Micron in the U.S. District Court for the Northern District of California. Rambus 
alleges  that  14  Rambus  patents  are  infringed  by  Micron’s  DDR2,  DDR3,  GDDR3,  and  other  advanced  memory  products.  Rambus 
seeks  compensatory  and  punitive  damages,  attorneys’  fees,  and  injunctive  relief.  Micron  has  denied  Rambus’  allegations  and  is 
alleging  counterclaims  for  violations  of  federal  antitrust  laws,  unfair  trade  practices,  equitable  estoppel,  fraud  and  negligent 
misrepresentation  in  connection  with  Rambus’  participation  in  JEDEC.  Micron  seeks  a  declaration  of  monopolization  by  Rambus, 
injunctive relief, compensatory and punitive damages, attorneys’ fees, and a declaratory judgment of invalidity, unenforceability, and 
noninfringement of the 14 patents in suit. 

As  explained  above,  the  court  ordered  a  coordinated  trial  (without  Samsung)  of  certain  common  JEDEC-related  claims  and 
defenses asserted in Hynix v Rambus, Case No. C 00-20905 RMW, Rambus Inc. v. Samsung Electronics Co. Ltd. et al., Case No. 05-
02298 RMW, Rambus Inc. v. Hynix Semiconductor Inc., et al., Case No. 05-00334, and Rambus Inc. v. Micron Technology, Inc., et 
al., Case No. C 06-00244 RMW. The coordinated trial involving Rambus, Hynix, Micron and Nanya began on January 29, 2008, and 
was submitted to the jury on March 25, 2008. On March 26, 2008, the jury returned a verdict in favor of Rambus and against Hynix, 
Micron, and Nanya on each of their claims. Specifically, the jury found that Hynix, Micron, and Nanya failed to meet their burden of 
proving  that:  (1) Rambus  engaged  in  anticompetitive  conduct;  (2) Rambus  made  important  representations  that  it  did  not  have  any 
intellectual property pertaining to the work of JEDEC and intended or reasonably expected that the representations would be heard by 
or  repeated  to  others  including  Hynix,  Micron  or  Nanya;  (3) Rambus  uttered  deceptive  half-truths  about  its  intellectual  property 
coverage  or  potential  coverage  of  products  compliant  with  synchronous  DRAM  standards  then  being  considered  by  JEDEC  by 
disclosing some facts but failing to disclose other important facts; or (4) JEDEC members shared a clearly defined expectation that 
members would disclose relevant knowledge they had about patent applications or the intent to file patent applications on technology 
being  considered  for  adoption  as  a  JEDEC  standard.  Hynix,  Micron,  and  Nanya  filed  motions  for  a  new  trial  and  for  judgment  on 
certain  of  their  equitable  claims  and  defenses.  A  hearing  on  those  motions  was  held  on  May 1,  2008.  A  further  hearing  on  the 
equitable claims and defenses was held on May 27, 2008. On July 24, 2008, the court issued an order denying Hynix, Micron, and 
Nanya’s motions for new trial.  

On March 3, 2009, the court issued an order rejecting Hynix, Micron, and Nanya’s equitable claims and defenses that had been 
tried during the coordinated trial. The court concluded (among other things) that (1) Rambus did not have an obligation to disclose 
pending or anticipated patent applications and had sound reasons for not doing so; (2) the evidence supported the jury’s finding that 
JEDEC members did not share a clearly defined expectation that members would disclose relevant knowledge they had about patent 
applications or the intent to file patent applications on technology being considered for adoption as a JEDEC standard; (3) the written 
JEDEC  disclosure  policies  did  not  clearly  require  members  to  disclose  information  about  patent  applications  and  the  intent  to  file 
patent applications in the future; (4) there was no clearly understood or legally enforceable agreement of JEDEC members to disclose 
information about patent applications or the intent to seek patents relevant to standards being discussed at JEDEC; (5) during the time 
Rambus attended JEDEC meetings, Rambus did not have any patent application pending that covered a JEDEC standard, and none of 
the patents in suit was applied for until well after Rambus resigned from JEDEC; (6) Rambus’s conduct at JEDEC did not constitute 
an  estoppel  or  waiver  of  its  rights  to  enforce  its  patents;  (7) Hynix,  Micron,  and  Nanya  failed  to  carry  their  burden  to  prove  their 
asserted waiver and estoppel defenses not directly based on Rambus’s conduct at JEDEC; (8) the evidence did not support a finding of 
any material misrepresentation, half truths or fraudulent concealment by Rambus related to JEDEC upon which Nanya relied; (9) the 
manufacturers failed to establish that Rambus violated unfair competition law by its conduct before JEDEC; (10) the evidence related 

101 

 
 
 
 
 
 
 
to Rambus’s patent prosecution did not establish that Rambus unduly delayed in prosecuting the claims in suit; (11) Rambus did not 
unreasonably  delay  bringing  its  patent  infringement  claims;  and  (12) there  is  no  basis  for  any  unclean  hands  defense  or 
unenforceability claim arising from Rambus’s conduct. 

In these cases (except for the Hynix 00-20905 action), a hearing on claim construction and the parties’ cross-motions for summary 
judgment on infringement and validity was held on June 4 and 5, 2008. On July 10, 2008, the court issued its claim construction order 
relating  to  the  Farmwald/Horowitz  patents  in  suit  and  denied  Hynix,  Micron,  Nanya,  and  Samsung’s  (collectively,  the 
“Manufacturers”) motions for summary judgment of noninfringement and invalidity based on their proposed claim construction. The 
court  issued  claim  construction  orders  relating  to  the  Ware  patents  in  suit  on  July  25  and  August 27,  2008,  and  denied  the 
Manufacturers’ motion for summary judgment of noninfringement of certain claims. On September 4, 2008, at the court’s direction, 
Rambus elected to proceed to trial on 12 patent claims, each from the Farmwald/Horowitz family. On September 16, 2008, Rambus 
granted a covenant not to assert any claim of patent infringement against the Manufacturers under the Ware patents in suit (U.S. Patent 
Nos.  6,493,789  and  6,496,897),  and  each  party’s  claims  relating  to  those  patents  were  dismissed  with  prejudice.  On  November 21, 
2008, the court entered an order clarifying certain aspects of its July 10, 2008, claim construction order. On November 24, 2008, the 
court  granted  Rambus’  motion  for  summary  judgment  of  direct  infringement  with  respect  to  claim  16  of  Rambus’  U.S. Patent 
No. 6,266,285 by  the  Manufacturers’  DDR2,  DDR3,  gDDR2,  GDDR3, GDDR4  memory  chip  products  (except  for  Nanya’s DDR3 
memory chip products). In the same order, the court denied the remainder of Rambus’ motion for summary judgment of infringement. 

On  January 19,  2009,  Micron  filed  a  motion  for  summary  judgment  on  the  ground  that  the  Delaware  Order  should  be  given 
preclusive effect. Rambus filed an opposition to Micron’s motion on January 26, 2009, and a hearing was held on January 30, 2009. 
On February 3, 2009, the court entered a stay of this action pending resolution of Rambus’ appeal of the Delaware Order.  

European Patent Infringement Cases 

In 2001, Rambus filed suit against Micron in Mannheim, Germany, for infringement of European patent, EP 1 022 642. That suit 
has not been active. Two proceedings in Italy remain ongoing relating to Rambus’s claim that Micron is infringing European patent, 
EP 1 004 956, and Micron’s purported claim resulting from a seizure of evidence in Italy in 2000 carried out by Rambus pursuant to a 
court order.  

DDR2, DDR3, gDDR2, GDDR3, GDDR4 Litigation (“DDR2”) 

U.S District Court in the Northern District of California 

On  January 25,  2005,  Rambus  filed  a  patent  infringement  suit  in  the  U.S. District  Court  for  the  Northern  District  of  California 
court  against  Hynix,  Infineon,  Nanya,  and  Inotera.  Infineon  and  Inotera  were  subsequently  dismissed  from  this  litigation  as  was 
Samsung which had been added as a defendant. Rambus alleges that certain of its patents are infringed by certain of the defendants’ 
SDRAM,  DDR,  DDR2,  DDR3,  gDDR2,  GDDR3,  GDDR4  and  other  advanced  memory  products.  Hynix  and  Nanya  have  denied 
Rambus’ claims and asserted counterclaims against Rambus for, among other things, violations of federal antitrust laws, unfair trade 
practices, equitable estoppel, and fraud in connection with Rambus’ participation in JEDEC. 

As  explained  above,  the  court  ordered  a  coordinated  trial  (without  Samsung)  of  certain  common  JEDEC-related  claims  and 
defenses asserted in Hynix v Rambus, Case No. C 00-20905 RMW, Rambus Inc. v. Samsung Electronics Co. Ltd. et al., Case No. 05-
02298 RMW, Rambus Inc. v. Hynix Semiconductor Inc., et al., Case No. 05-00334, and Rambus Inc. v. Micron Technology, Inc., et 
al., Case No. C 06-00244 RMW. The coordinated trial involving Rambus, Hynix, Micron and Nanya began on January 29, 2008, and 
was submitted to the jury on March 25, 2008. On March 26, 2008, the jury returned a verdict in favor of Rambus and against Hynix, 
Micron, and Nanya on each of their claims. Specifically, the jury found that Hynix, Micron, and Nanya failed to meet their burden of 
proving  that:  (1) Rambus  engaged  in  anticompetitive  conduct;  (2) Rambus  made  important  representations  that  it  did  not  have  any 
intellectual property pertaining to the work of JEDEC and intended or reasonably expected that the representations would be heard by 
or  repeated  to  others  including  Hynix,  Micron  or  Nanya;  (3) Rambus  uttered  deceptive  half-  truths  about  its  intellectual  property 
coverage  or  potential  coverage  of  products  compliant  with  synchronous  DRAM  standards  then  being  considered  by  JEDEC  by 
disclosing some facts but failing to disclose other important facts; or (4) JEDEC members shared a clearly defined expectation that 
members would disclose relevant knowledge they had about patent applications or the intent to file patent applications on technology 
being  considered  for  adoption  as  a  JEDEC  standard.  Hynix,  Micron,  and  Nanya  filed  motions  for  a  new  trial  and  for  judgment  on 

102 

 
 
 
 
 
 
 
 
 
 
certain  of  their  equitable  claims  and  defenses.  A  hearing  on  those  motions  was  held  on  May 1,  2008.  A  further  hearing  on  the 
equitable claims and defenses was held on May 27, 2008. On July 24, 2008, the court issued an order denying Hynix, Micron, and 
Nanya’s motions for new trial.  

On March 3, 2009, the court issued an order rejecting Hynix, Micron, and Nanya’s equitable claims and defenses that had been 
tried during the coordinated trial. The court concluded (among other things) that (1) Rambus did not have an obligation to disclose 
pending or anticipated patent applications and had sound reasons for not doing so; (2) the evidence supported the jury’s finding that 
JEDEC members did not share a clearly defined expectation that members would disclose relevant knowledge they had about patent 
applications or the intent to file patent applications on technology being considered for adoption as a JEDEC standard; (3) the written 
JEDEC  disclosure  policies  did  not  clearly  require  members  to  disclose  information  about  patent  applications  and  the  intent  to  file 
patent applications in the future; (4) there was no clearly understood or legally enforceable agreement of JEDEC members to disclose 
information about patent applications or the intent to seek patents relevant to standards being discussed at JEDEC; (5) during the time 
Rambus attended JEDEC meetings, Rambus did not have any patent application pending that covered a JEDEC standard, and none of 
the patents in suit was applied for until well after Rambus resigned from JEDEC; (6) Rambus’s conduct at JEDEC did not constitute 
an  estoppel  or  waiver  of  its  rights  to  enforce  its  patents;  (7) Hynix,  Micron,  and  Nanya  failed  to  carry  their  burden  to  prove  their 
asserted waiver and estoppel defenses not directly based on Rambus’s conduct at JEDEC; (8) the evidence did not support a finding of 
any material misrepresentation, half truths or fraudulent concealment by Rambus related to JEDEC upon which Nanya relied; (9) the 
manufacturers failed to establish that Rambus violated unfair competition law by its conduct before JEDEC; (10) the evidence related 
to Rambus’s patent prosecution did not establish that Rambus unduly delayed in prosecuting the claims in suit; (11) Rambus did not 
unreasonably  delay  bringing  its  patent  infringement  claims;  and  (12) there  is  no  basis  for  any  unclean  hands  defense  or 
unenforceability claim arising from Rambus’s conduct. 

In these cases (except for the Hynix 00-20905 action), a hearing on claim construction and the parties’ cross-motions for summary 
judgment on infringement and validity was held on June 4 and 5, 2008. On July 10, 2008, the court issued its claim construction order 
relating to the Farmwald/Horowitz patents in suit and denied the Manufacturers’ motions for summary judgment of noninfringement 
and invalidity based on their proposed claim construction. The court issued claim construction orders relating to the Ware patents in 
suit  on  July  25  and  August 27,  2008,  and  denied  the  Manufacturers’  motion  for  summary  judgment  of  noninfringement  of  certain 
claims.  On  September 4,  2008,  at  the  court’s  direction,  Rambus  elected  to  proceed  to  trial  on  12  patent  claims,  each  from  the 
Farmwald/Horowitz  family.  On  September 16,  2008,  Rambus  granted  a  covenant  not  to  assert  any  claim  of  patent  infringement 
against  the  Manufacturers  under  U.S. Patent  Nos.  6,493,789  and  6,496,897,  and  each  party’s  claims  relating  to  those  patents  were 
dismissed  with  prejudice.  On  November 21,  2008,  the  court  entered  an  order  clarifying  certain  aspects  of  its  July 10,  2008,  claim 
construction order.  On  November 24,  2008,  the  court granted  Rambus’s  motion  for  summary  judgment  of direct  infringement  with 
respect to claim 16 of Rambus’s U.S. Patent No. 6,266,285 by the Manufacturers’ DDR2, DDR3, gDDR2, GDDR3, GDDR4 memory 
chip  products  (except  for  Nanya’s  DDR3  memory  chip  products).  In  the  same  order,  the  court  denied  the  remainder  of  Rambus’s 
motion for summary judgment of infringement. 

On January 19, 2009, Nanya and Hynix filed motions for summary judgment on the ground that the Delaware Order should be 
given preclusive effect. Rambus filed opposition briefs to these motions on January 26, 2009, and a hearing was held on January 30, 
2009. On February 3, 2009, the court entered a stay of this action pending resolution of Rambus’ appeal of the Delaware Order.  

European Commission Competition Directorate-General 

On  or  about  April 22,  2003,  Rambus  was  notified  by  the  European  Commission  Competition  Directorate-General  (Directorate) 
(the “European Commission”) that it had received complaints from Infineon and Hynix. Rambus answered the ensuing requests for 
information  prompted  by  those  complaints  on  June 16,  2003.  Rambus  obtained  a  copy  of  Infineon’s  complaint  to  the  European 
Commission in late July 2003, and on October 8, 2003, at the request of the European Commission, filed its response. The European 
Commission sent Rambus a further request for information on December 22, 2006, which Rambus answered on January 26, 2007. On 
August 1, 2007, Rambus received a statement of objections from the European Commission. The statement of objections alleges that 
through  Rambus’  participation  in  the  JEDEC  standards  setting  organization  and  subsequent  conduct,  Rambus  violated  European 
Union  competition  law.  Rambus  filed  a  response  to  the  statement  of  objections  on  October 31,  2007,  and  a  hearing  was  held  on 
December 4 and 5, 2007.

On  December  9,  2009,  the  European  Commission  announced  that  it  has  reached  a  final  settlement  with  Rambus  to  resolve  the 
pending case. Under the terms of the settlement, the Commission made no finding of liability, and no fine will be assessed against 
Rambus.  Rambus  commits  to  offer  licenses  with  maximum  royalty  rates  for  certain  memory  types  and  memory  controllers  on  a 
forward-going basis (the “Commitment”). The Commitment is expressly made without any admission by Rambus of the allegations 
asserted against it. The Commitment also does not resolve any existing claims of infringement prior to the signing of any license with 
a prospective licensee, nor does it release or excuse any of the prospective licensees from damages or royalty obligations through the 
date of signing a license. Rambus offers licenses with maximum royalty rates for five-year worldwide licenses of 1.5% for DDR2, 
DDR3,  GDDR3  and  GDDR4  SDRAM  memory  types.  Qualified  licensees  will  enjoy  a  royalty  holiday  for  SDR  and  DDR  DRAM 
devices, subject to compliance with the terms of the license. In addition, Rambus offers licenses with maximum royalty rates for five-
year worldwide licenses of 1.5% per unit for SDR memory controllers through April 2010, dropping to 1.0% thereafter, and royalty 
rates  of  2.65%  per  unit  for  DDR,  DDR2,  DDR3,  GDDR3  and  GDDR4  memory  controllers  through  April  2010,  then  dropping  to 
2.0%. The Commitment to license at the above rates remains valid for a period of five years from December 9, 2009. All royalty rates 
are applicable to future shipments only and do not affect liability, if any, for damages or royalties that accrued up to the time of the 
license grant.  

On March 25, 2010, Hynix filed appeals with the General Court of the European Union purporting to challenge the settlement and 

the European Commission’s rejection of Hynix’s complaint. No decision has issued to date on Hynix’s appeal.  

Superior Court of California for the County of San Francisco 

On  May 5,  2004,  Rambus  filed  a  lawsuit  against  Micron,  Hynix,  Infineon  and  Siemens  in  San Francisco  Superior  Court  (the 
“San Francisco court”) seeking damages for conspiring to fix prices (California Bus. & Prof. Code §§ 16720 et seq.), conspiring to 
monopolize  under  the  Cartwright  Act  (California  Bus.  &  Prof.  Code  §§ 16720  et  seq.),  intentional  interference  with  prospective 
economic  advantage,  and  unfair  competition  (California  Bus.  &  Prof.  Code  §§ 17200  et  seq.).  This  lawsuit  alleges  that  there  were 
concerted  efforts  beginning  in  the  1990s  to  deter  innovation  in  the  DRAM  market  and  to  boycott  Rambus  and/or  deter  market 
acceptance  of  Rambus’  RDRAM  product.  Subsequently,  Infineon  and  Siemens  were  dismissed  from  this  action  (as  a  result  of  a 
settlement with Infineon) and three Samsung-related entities were added as defendants and later dismissed (as a result of a settlement 
with Samsung). 

A  jury  trial  against  Micron  and  Hynix  began  on  June  20,  2011.  On  September  21,  2011,  the  jury  began  deliberations.  On 
November 16, 2011, the jury returned a verdict in favor of Hynix and Micron and against Rambus by a tally of 9-3. Judgment was 
entered by the Court on February 15, 2012. Rambus’ notice of appeal is not due until April 16, 2012.  

On  February  15,  2012,  Micron  and  Hynix  filed  memoranda  of  costs  seeking  to  recover  approximately  $1.6  million  and  $3.0 

million, respectively, in alleged costs from Rambus. Rambus’ opposition is due April 2, 2012. 

Stock Option Investigation Related Claims 

On May 30, 2006, the Audit Committee commenced an internal investigation of the timing of past stock option grants and related 

accounting issues. 

On May 31, 2006, the first of three shareholder derivative actions was filed in the U.S. District Court for the Northern District of 
California  against  Rambus  (as  a  nominal  defendant)  and  certain  current  and  former  executives  and  board  members.  These  actions 
were consolidated for all purposes under the caption, In re Rambus Inc. Derivative Litigation, Master File No. C-06-3513-JF (N.D. 
Cal.),  and  Howard  Chu  and  Gaetano  Ruggieri  were  appointed  lead  plaintiffs.  The  consolidated  complaint,  as  amended,  alleged 
violations of certain federal and state securities laws as well as other state law causes of action. The complaint sought disgorgement 
and damages in an unspecified amount, unspecified equitable relief, and attorneys’ fees and costs. 

On August 30, 2007, another shareholder derivative action was filed in the U.S. District Court for the Southern District of New 
York  against  Rambus  (as  a  nominal  defendant)  and  PricewaterhouseCoopers  LLP  (Francl v.  PricewaterhouseCoopers  LLP  et  al., 
No. 07-Civ. 7650 (GBD)). On November 21, 2007, the New York court granted PricewaterhouseCoopers LLP’s motion to transfer the 
action to the Northern District of California.

On October 18, 2006, the Board of Directors formed a Special Litigation Committee (the “SLC”) to evaluate potential claims or 
other actions arising from the stock option granting activities. The Board of Directors appointed J. Thomas Bentley, Chairman of the 
Audit Committee, and Abraham Sofaer, a retired federal judge and Chairman of the Legal Affairs Committee, both of whom joined 
the Rambus Board of Directors in 2005, to comprise the SLC. 

On August 24, 2007, the final written report setting forth the findings of the SLC was filed with the court. As set forth in its report, 
the SLC determined that all claims should be terminated and dismissed against the named defendants in In re Rambus Inc. Derivative 
Litigation with the exception of claims against named defendant Ed Larsen, who served as Vice President, Human Resources from 
September  1996  until  December  1999,  and  then  Senior  Vice  President,  Administration  until  July  2004.  The  SLC  entered  into 
settlement agreements with certain former officers of Rambus. The aggregate value of the settlements to Rambus exceeds $5.3 million 
in cash as well as substantial additional value to Rambus relating to the relinquishment of claims to over 2.7 million stock options. On 
October 5, 2007, Rambus filed a motion to terminate in accordance with the SLC’s recommendations. Subsequently, the parties settled 
In re Rambus Inc. Derivative Litigation and Francl v. PricewaterhouseCoopers LLP et al., No. 07-Civ. 7650 (GBD). The settlement 
provided  for  a  payment  by  Rambus  of  $2.0 million  and  dismissal  with  prejudice  of  all  claims  against  all  defendants,  with  the 
exception of claims against Ed Larsen (which have now also been settled), in these actions. The $2.0 million was accrued for during 
the quarter ended June 30, 2008 within accrued litigation expenses and paid in January 2009. A final approval hearing was held on 
January 16, 2009, and an order of final approval was entered on January 20, 2009. 

On July 17, 2006, the first of six class action lawsuits was filed in the U.S. District Court for the Northern District of California 
against Rambus and certain current and former executives and board members. These lawsuits were consolidated under the caption, In 
re Rambus Inc. Securities Litigation, C-06-4346-JF (N.D. Cal.). The settlement of this action was preliminarily approved by the court 
on March 5, 2008. Pursuant to the settlement agreement, Rambus paid $18.3 million into a settlement fund on March 17, 2008. Some 
alleged class members requested exclusion from the settlement. A final fairness hearing was held on May 14, 2008. That same day the 
court entered an order granting final approval of the settlement agreement and entered judgment dismissing with prejudice all claims 
against all defendants in the consolidated class action litigation. 

On March 1, 2007, a pro se lawsuit was filed in the Northern District of California by two alleged Rambus shareholders against 
Rambus, certain current and former executives and board members, and PricewaterhouseCoopers LLP (Kelley et al. v. Rambus, Inc. et 
al. C-07-01238-JF (N.D. Cal.)). This action was consolidated with a substantially identical pro se lawsuit filed by another purported 
Rambus  shareholder  against  the  same  parties.  The  consolidated  complaint  against  Rambus  alleges  violations  of  federal  and  state 
securities  laws,  and  state  law  claims  for  fraud  and  breach  of  fiduciary  duty.  Following  several  rounds  of  motions  to  dismiss,  on 
April 17,  2008,  the  court  dismissed  all  claims  with  prejudice  except  for  plaintiffs’  claims  under  sections 14(a)  and  18(a)  of  the 
Securities and Exchange Act of 1934 as to which leave to amend was granted. On June 2, 2008, plaintiffs filed an amended complaint 
containing substantially the same allegations as the prior complaint although limited to claims under sections 14(a) and 18(a) of the 
Securities  and  Exchange  Act  of  1934.  Rambus’  motion  to  dismiss  the  amended  complaint  was  heard  on  September 12,  2008.  On 
December 9, 2008, the court granted Rambus’ motion and entered judgment in favor of Rambus. Plaintiffs filed a notice of appeal on 
December 15, 2008. Plaintiffs’ filed their opening brief on April 13, 2009. Rambus opposed on May 29, 2009, and plaintiffs filed a 
reply brief on June 12, 2009. On June 16, 2010, the United States Court of Appeals for the Ninth Circuit issued a decision affirming 
the judgment in favor of Rambus.  

On September 11, 2008, the same pro se plaintiffs filed a separate lawsuit in Santa Clara County Superior Court against Rambus, 
certain current and former executives and board members, and PricewaterhouseCoopers LLP (Kelley et al. v. Rambus, Inc. et al., Case 
No. 1-08-CV-122444).  The  complaint  alleges  violations  of  certain  California  state  securities  statues  as  well  as  fraud  and  negligent 
misrepresentation based on substantially the same underlying factual allegations contained in the pro se lawsuit filed in federal court. 
On October 31, 2010, the plaintiffs filed a second amended complaint. On December 2, 2010, Rambus filed a demurrer to plaintiffs’ 
second amended complaint on the ground that it is barred by the doctrine of claim preclusion, among other things. On May 12, 2011, 
the  court  sustained  Rambus’  demurrer  without  leave  to  amend.  Judgment  in  favor  of  Rambus  was  entered  on  June  15,  2011.  On 
August 10, 2011, plaintiffs filed a notice of appeal.  

On  August 25,  2008,  an  amended  complaint  was  filed  by  certain  individuals  and  entities  in  Santa Clara  County  Superior  Court 
against Rambus, certain current and former executives and board members, and PricewaterhouseCoopers LLP (Steele et al. v. Rambus 
Inc. et al., Case No. 1-08-CV-113682). The amended complaint alleges violations of certain California state securities statues as well 
as fraud and negligent misrepresentation. On October 10, 2008, Rambus filed a demurrer to the amended complaint. A hearing was 

105 

 
 
 
 
 
 
 
held  on  January 9,  2009.  On  January 12,  2009,  the  court  sustained  Rambus’  demurrer  without  prejudice.  Plaintiffs  filed  a  second 
amended  complaint  on  February 13,  2009,  containing  the  same  causes  of  action  as  the  previous  complaint.  On  March  17,  2009, 
Rambus  filed  a  demurrer  to  the  second  amended  complaint.  A  hearing  was  held  on  May  22,  2009.  On  May  26,  2009,  the  court 
sustained in part and overruled in part Rambus’s demurrer. On June 5, 2009, Rambus filed an answer denying plaintiffs’ remaining 
allegations. On December 20, 2011, Rambus agreed to settle the claims against it and the individual defendants for $10.85 million.  

NVIDIA Litigation 

U.S District Court in the Northern District of California 

On July 10, 2008, Rambus filed suit against NVIDIA Corporation (“NVIDIA”) in the U.S. District Court for the Northern District 
of California alleging that NVIDIA’s products with memory controllers for SDR, DDR, DDRx, GDDR, and GDDRy (where DDRx 
and GDDRy includes at least DDR2, DDR3 and GDDR3) technologies infringe 17 patents. On September 16, 2008, Rambus granted 
a  covenant  not  to  assert  any  claim  of  patent  infringement  against  NVIDIA  under  two  of  the  patents  in  suit—U.S. Patent  Nos. 
6,493,789  and  6,496,897.  On  August  1,  2011,  NVIDIA  filed  an  answer  denying  Rambus’s  claims  and  counterclaims  alleging 
violations  of  federal  antitrust  laws,  breach  of  contract,  promissory  estoppel,  and  deceptive  practices  in  connection  with  Rambus’ 
participation in JEDEC and alleged spoliation of evidence. NVIDIA seeks a declaratory judgment that the Rambus patents-in-suit are 
unenforceable,  invalid  and  not  infringed  by  NVIDIA,  compensatory  and  other  damages,  injunctive  relief,  and  attorneys’  fees.  On 
December 1, 2010, Rambus filed suit against NVIDIA in the U.S. District Court for the Northern District of California alleging that 
NVIDIA’s  products  with  certain  peripheral  interfaces,  including  PCI  Express  and  DisplayPort  peripheral  interfaces,  infringe  six 
patents  from  the  Dally  family  of  patents  which  are  owned  by  Massachusetts  Institute  of  Technology  and  exclusively  licensed  by 
Rambus. On January 20, 2011, NVIDIA filed a motion to stay the case pending resolution of the 2010 ITC investigation (described 
below).  On  January  25,  2011,  the  court  granted  NVIDIA’s  motion.  On  February  7,  2012,  Rambus  and  NVIDIA  entered  into  a 
settlement  agreement  pursuant  to  which  the  parties  agreed  to  release  all  claims  against  each  other  with  respect  to  all  outstanding 
litigation between them, including these district court cases. On February 14, 2012, all pending claims and counterclaims in this action 
were dismissed.  

International Trade Commission 2008 Investigation 

On  November 6,  2008,  Rambus  filed  a  complaint  with  the  U.  S.  International  Trade  Commission  (the  “ITC”)  requesting  the 
commencement of an investigation pertaining to NVIDIA products. The complaint seeks an exclusion order barring the importation, 
sale  for  importation,  or  sale  after  importation  of  products  that  infringe  nine  Rambus  patents  from  the  Ware  and  Barth  families  of 
patents.  The  accused  products  include  NVIDIA  products  that  incorporate  DDR,  DDR2,  DDR3,  LPDDR,  GDDR,  GDDR2,  and 
GDDR3  memory  controllers,  including  graphics  processors,  and  media  and  communications  processors.  The  complaint  names 
NVIDIA as a proposed respondent, as well as companies whose products incorporate accused NVIDIA products and are imported into 
the  United  States.  Additional  respondents  include:  Asustek  Computer  Inc.  and  Asus  Computer  International,  BFG  Technologies, 
Biostar  Microtech  and  Biostar  Microtech International  Corp.,  Diablotek  Inc.,  EVGA  Corp., G.B.T.  Inc.  and Giga-Byte  Technology 
Co., Hewlett-Packard, MSI Computer Corp. and Micro-Star International Co., Palit Multimedia Inc. and Palit Microsystems Ltd., Pine 
Technology Holdings, and Sparkle Computer Co. 

On December 4, 2008, the ITC instituted the investigation. A hearing on claim construction was held on March 24, 2009, and a 
claim construction order issued on June 22, 2009. On June 5, 2009, Rambus moved to withdraw from the investigation four of the 
asserted patents and certain claims of a fifth asserted patent in order to simplify the investigation, streamline the final hearing, and 
conserve Commission resources. A final hearing before the administrative law judge was held October 13-20, 2009, and the parties 
submitted two rounds of post-hearing briefs.  

On January 22, 2010, the administrative law judge issued a final initial determination holding that the importation of the accused 
NVIDIA  products  violates  section  337  of  the  Tariff  Act  of  1930,  as  amended,  19  U.S.C.  § 1337  because  they  infringe  seventeen 
claims  of  three  asserted  Barth  patents.  The  administrative  law  judge  held  that  the  accused  NVIDIA  products  literally  infringe  all 
asserted claims of each asserted Barth and Ware patent, that they infringe three asserted claims under the doctrine of equivalents, that 
respondents contribute to and induce infringement of all asserted claims, and that the asserted patents are not unenforceable due to 
unclean hands or equitable estoppel. The administrative law judge held that the asserted Barth patents are not invalid for anticipation 
or obviousness and are not obvious for double patenting. The administrative law judge further held that, while the accused products 

106 

 
 
 
 
 
 
 
 
 
infringed eight claims of the two asserted Ware patents and that those patents are not unenforceable due to inequitable conduct, no 
violation has occurred because the asserted Ware patents are invalid due to anticipation and obviousness. The administrative law judge 
recommended  that  the  ITC  issue  (1) a  limited  exclusion  order  prohibiting  the  unlicensed  importation  of  accused  products  by  any 
respondent; and (2) a cease and desist order prohibiting domestic respondents from engaging in certain activities in the United States 
with respect to the accused products. On February 12, 2010, the parties’ filed petitions asking the full Commission to review certain 
aspects of the final initial determination.  

On  March  25,  2010,  the  ITC  determined  to  review  certain  obviousness  findings  regarding  the  Barth  patents  and  certain 
obviousness and anticipation findings regarding the Ware patents. The parties have submitted briefing on these issues and on the issue 
of remedy and bonding. On May 24, 2010, the ITC extended the target date for completion of the investigation by two days to May 
26, 2010. On May 26, 2010, the ITC requested further briefing on the impact of the license between Rambus and Samsung on the 
administrative  law  judge’s  findings  and  conclusions,  particularly  on  the  issue  of  patent  exhaustion.  On  June  7,  2010  and  June  15, 
2010, the parties filed briefs as requested by the ITC. On June 22, 2010, the ITC requested additional briefing to discuss the relevance 
and effect with respect to the issue of patent exhaustion of a decision issued on May 27, 2010, by the United States Court of Appeals 
for the Federal Circuit in a case captioned Fujifilm Corp. v. Benun. On June 25, 2010, the parties filed briefs as requested by the ITC.  

On July 26, 2010, the ITC issued its final determination affirming the administrative law judge’s initial determination with certain 
modifications to provide further analysis of issues related to obviousness. The ITC found that respondents failed to demonstrate that 
Rambus’ patent rights are exhausted with respect to accused products that incorporate Samsung memory. The ITC issued (1) a limited 
exclusion order prohibiting the unlicensed importation by any respondent of memory controller products and products incorporating a 
memory controller that infringe one or more of the seventeen claims of three asserted Barth patents; and (2) a cease and desist order 
prohibiting respondents with commercially significant inventories of infringing products in the United States from importing, selling, 
marketing, advertising, distributing, offering for sale, transferring (except for exportation), and soliciting U.S. agents or distributors 
for, memory controller products and products incorporating a memory controller that infringe one or more of the seventeen claims of 
three asserted Barth patents, in violation of 19 U.S.C. § 1337. The ITC determined that the amount of the bond to permit importation 
during  the  sixty-day  Presidential  review  period  was  2.65  percent  of  the  entered  value  of  the  subject  imports.  The  ITC  denied 
respondents’  request  for stay  and  terminated  the  investigation. The  parties  have  each filed  opening, responsive,  and  reply  appellate 
briefs with the Federal Circuit. Oral argument was held on October 6, 2011. 

On February 7, 2012, Rambus and NVIDIA entered into a settlement agreement pursuant to which the parties agreed to release all 
claims against each other with respect to all outstanding litigation between them, including this ITC investigation. On February 10, 
2012, the appeals filed by NVIDIA and Rambus were dismissed by the Federal Circuit. On February 13, 2012, Rambus filed a motion 
to dismiss the Federal Circuit appeal filed by the additional named respondents as moot due to the settlement with NVIDIA. The only 
party that indicated it would oppose this motion was Hewlett Packard. On February 17, 2012, the ITC filed a response stating that it 
agreed with Rambus to the extent that Hewlett Packard was seeking an advisory opinion and asked the Federal Circuit to remand the 
case if Hewlett Packard was disputing the coverage of the license. Hewlett Packard has not yet filed a responsive brief and no decision 
has issued to date. 

International Trade Commission 2010 Investigation 

On December 1, 2010, Rambus filed a complaint with the ITC requesting the commencement of an investigation and seeking an 
exclusion order barring the importation, sale for importation, or sale after importation of, among other things, NVIDIA products with 
certain peripheral interfaces, including PCI Express and DisplayPort peripheral interfaces, that Rambus alleges infringe three patents 
from  the  Dally  family.  The  complaint  names,  among  others,  NVIDIA  as  a  respondent,  as  well  as  companies  whose  products 
incorporate accused NVIDIA products and are imported into the United States, including Asustek Computer Inc. and Asus Computer 
International  Inc.,  Biostar  Microtech  (U.S.A.)  Corp.,  Biostar  Microtech  International  Corp.,  Elitegroup  Computer  Systems,  EVGA 
Corp.,  Galaxy  Microsystems  Ltd.,  G.B.T.  Inc.,  Giga-Byte  Technology  Co.  Ltd.,  Gracom  Technologies  LLC,  Hewlett-Packard 
Company,  Jaton  Corp.,  Jaton  Technology  TPE,  Micro-Star  International  Co.,  MSI  Computer  Corp.,  Palit  Microsystems  Ltd.,  Pine 
Technology Holdings, Ltd., Sparkle Computer Co., Ltd., Zotac International (MCO) Ltd. and Zotac USA Inc. On December 29, 2010, 
the ITC instituted the investigation. A final hearing before the administrative law judge was held October 12-20, 2011. On February 7, 
2012, Rambus and NVIDIA entered into a settlement agreement pursuant to which the parties agreed to release all claims against each 
other  with  respect  to  all  outstanding  litigation  between  them,  including  this  ITC  investigation.  On  February  10,  2012  Rambus  and 

107 

 
 
 
 
 
  
 
NVIDIA filed a joint motion to terminate the investigation as to NVIDIA pursuant to the parties’ settlement agreement.  To date, the 
administrative law judge has not ruled on the motion. 

Broadcom, Freescale, LSI, MediaTek, and STMicroelectronics Litigation 

International Trade Commission 2010 Investigation 

On December 1, 2010, Rambus filed a complaint with the ITC requesting the commencement of an investigation and seeking an 
exclusion  order  barring  the  importation,  sale  for  importation,  or  sale  after  importation  of  products  that  incorporate  at  least  DDR, 
DDR2, DDR3, LPDDR, LPDDR2, mobile DDR, GDDR, GDDR2, and GDDR3 memory controllers from Broadcom, Freescale, LSI, 
MediaTek  and  STMicroelectronics  that  infringe  patents  from  the  Barth  family  of  patents,  and  products  having  certain  peripheral 
interfaces, including PCI Express interfaces, DisplayPort interfaces, and certain Serial AT Attachment (“SATA”) and Serial Attached 
SCSI  (“SAS”)  interfaces,  from  Broadcom,  Freescale,  LSI  and  STMicroelectronics  that  infringe  patents  from  the  Dally  family  of 
patents.  The complaint names, among others, Broadcom, Freescale, LSI, MediaTek and STMicroelectronics as respondents, as well 
as  companies  whose  products  incorporate  those  companies’  accused  products  and  are  imported  into  the  United  States,  including 
Asustek  Computer  Inc.  and Asus  Computer  International  Inc.,  Audio  Partnership  Plc,  Cisco  Systems,  Garmin  International, G.B.T. 
Inc.,  Giga-Byte  Technology  Co.  Ltd.,  Gracom  Technologies  LLC,  Hewlett-Packard  Company,  Hitachi  GST,  Motorola,  Inc.,  Oppo 
Digital,  Inc.,  and  Seagate  Technology.  As  described  more  fully  above,  the  complaint  also  names  NVIDIA  and  certain  companies 
whose  products  incorporate  accused  NVIDIA  products  with  certain  peripheral  interfaces,  including  PCI  Express  and  DisplayPort 
peripheral interfaces, and seeks to bar their importation, sale for importation, or sale after importation.  On December 29, 2010, the 
ITC instituted the investigation. On June 20, 2011, the administrative law judge granted a joint motion by Rambus and Freescale to 
terminate the investigation as to Freescale pursuant to the parties’ settlement agreement. A final hearing before the administrative law 
judge  was  held  October  12-20,  2011.  On  January  17,  2012,  the  administrative  law  judge  granted  a  joint  motion  by  Rambus  and 
Broadcom to terminate the investigation as to Broadcom pursuant to the parties’ settlement agreement.  The final initial determination 
is due on or before March 2, 2012, and the target date for the decision of the full Commission is July 2, 2012.  

U.S District Court in the Northern District of California 

On  December  1,  2010,  Rambus  filed  complaints  against  Broadcom,  Freescale,  LSI,  MediaTek  and  STMicroelectronics  in  the 
U.S. District  Court  for  the  Northern  District  of  California  alleging  that  1) products  that  incorporate  at  least  DDR,  DDR2,  DDR3, 
LPDDR, LPDDR2, mobile DDR, GDDR, GDDR2, and GDDR3 memory controllers from Broadcom, Freescale, LSI, MediaTek and 
STMicroelectronics infringe patents from the Barth family of patents; 2) those same products and products from those companies that 
incorporate SDR memory controllers infringe patents from the Farmwald-Horowitz family; and 3) products having certain peripheral 
interfaces,  including  PCI  Express,  DisplayPort,  and  certain  SATA  and  SAS  interfaces,  from  Broadcom,  Freescale,  LSI  and 
STMicroelectronics infringe patents from the Dally family of patents. On June 7, 2011, Rambus’s complaint against Freescale was 
dismissed  pursuant  to  the  parties’  settlement  agreement.  On  January  24,  January  26,  and  March  1,  2011,  LSI,  Broadcom,  and 
STMicroelectronics filed their respective answers denying Rambus’s allegations and asserting counterclaims seeking declarations of 
non-infringement  and  invalidity,  and  unenforceability  with  respect  to  at  least  certain  of  the  patents  in  suit.  Rambus  filed  answers 
denying the allegations in LSI’s, Broadcom’s, and STMicroelectronics’ counterclaims on February 14, February 16, and March 22, 
2011,  respectively.  On  March  7,  2011,  MediaTek  filed  an  answer  denying  Rambus’s  allegations. On  January  28, 2011,  Broadcom, 
Mediatek, and LSI filed motions to stay their respective actions. On February 4, 2011, STMicroelectronics filed a motion to stay its 
action. Rambus has opposed entry of any stay as to certain patents not overlapping with patents asserted in the ITC 2010 investigation. 
On June 13, 2011, the Court granted in part the motions to stay and denied them as to certain patents not overlapping with patents 
asserted in the ITC 2010 investigation. On December 29, 2011, Rambus’s complaint against Broadcom was dismissed pursuant to the 
parties’ settlement agreement. Discovery is ongoing.  

Potential Future Litigation 

In addition to the litigation described above, companies continue to adopt Rambus technologies into various products. Rambus has 

notified many of these companies of their use of Rambus technology and continues to evaluate how to proceed on these matters.  

There can be no assurance that any ongoing or future litigation will be successful. Rambus spends substantial company resources 
defending its intellectual property in litigation, which may continue for the foreseeable future given the multiple pending litigations. 

108 

 
 
 
 
 
 
 
 
 
 
The outcomes of these litigations — as well as any delay in their resolution — could affect Rambus’ ability to license its intellectual 
property in the future.  

The  Company  records  a  contingent  liability  when  it  is  probable  that  a  loss  has  been  incurred  and  the  amount  is  reasonably 
estimable in accordance with accounting for contingencies. A reasonably possible loss in excess of amounts accrued is not significant 
to the financial statements. 

17.  Fair Value of Financial Instruments 

The fair value measurement statement defines fair value as the price that would be received from selling an asset or paid to transfer 
a liability in an orderly transaction between market participants at the measurement date. When determining fair value, the Company 
considers the principal or most advantageous market in which the Company would transact, and the Company considers assumptions 
that  market  participants  would  use  when  pricing  the  asset  or  liability,  such  as  inherent  risk,  transfer  restrictions,  and  risk  of  non-
performance.  

The Company’s financial instruments are measured and recorded at fair value, except for cost method investments and convertible 
notes. The Company’s non-financial assets, such as goodwill, intangible assets, and property, plant and equipment, are measured at 
fair value when there is an indicator of impairment and recorded at fair value only when an impairment charge is recognized. 

Fair Value Hierarchy 

The  fair  value  measurement  statement  requires  disclosure  that  establishes  a  framework  for  measuring  fair  value  and  expands 
disclosure  about  fair  value  measurements.  The  statement  requires  fair  value  measurement  be  classified  and  disclosed  in  one  of  the 
following three categories: 

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or 

liabilities. 

The Company uses unadjusted quotes to determine fair value. The financial assets in Level 1 include money market funds. 

Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially 

the full term of the asset or liability. 

The Company uses observable pricing inputs including benchmark yields, reported trades, and broker/dealer quotes. The financial 

assets in Level 2 include U.S. government bonds and notes, corporate notes, commercial paper and municipal bonds and notes. 

Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable 

(i.e., supported by little or no market activity). 

The financial assets in Level 3 include a cost investment whose value is determined using inputs that are both unobservable and 

significant to the fair value measurements.  

The  Company  tests  the  pricing  inputs  by  obtaining  prices  from  two  different  sources  for  the  same  security  on  a  sample  of  its 
portfolio. The Company has not adjusted the pricing inputs it has obtained. The following table presents the financial instruments that 
are carried at fair value and summarizes the valuation of its cash equivalents and marketable securities by the above pricing levels as 
of December 31, 2011 and December 31, 2010:

The Company monitors the investment for other-than-temporary impairment and record appropriate reductions in carrying value 
when necessary. The Company made an investment of $2.0 million in a non-marketable equity security of a private company during 
the third quarter of 2009. The Company evaluated the fair value of the investment in the non-marketable security as of December 31, 
2011 and determined that there were no events that caused a decrease in its fair value below the carrying cost.

As of December 31, 2010 

The  fair  value  of  the  convertible  notes  at  each  balance  sheet  date  is  determined  based  on  recent  quoted  market  prices  for  these 
notes.  As  discussed  in  Note  15,  “Convertible  Notes,”  as  of  December  31,  2011,  the  convertible  notes  are  carried  at  face  value  of 
$172.5  million  less  any  unamortized  debt  discount.  The  carrying  value  of  other  financial  instruments,  including  cash,  accounts 
receivable, accounts payable and other payables, approximates fair value due to their short maturities. 

The  Company  monitors  its  investments  for  other  than  temporary  losses  by  considering  current  factors,  including  the  economic 
environment,  market  conditions,  operational  performance,  specific  factors  relating  to  the  business  underlying  the  investment,

reductions in carrying values when applicable and the Company’s ability and intent to hold the investment for a period of time which 
may be sufficient for anticipated recovery in the market. Any other than temporary loss is reported under “Interest and other income 
(expense), net” in the consolidated statement of operations. For the year ended December 31, 2011, the Company has not incurred any 
impairment loss on its investments. 

18.  Acquisitions 

On May 12, 2011, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Padlock 
Acquisition Corp., a California corporation and wholly-owned subsidiary of the Company (“Merger Sub”), CRI, a California 
corporation, and the shareholder representative party thereto. On June 3, 2011, the Company completed its acquisition of CRI by 
acquiring all issued and outstanding common shares of CRI. Pursuant to the terms of the Merger Agreement, on June 3, 2011, Merger 
Sub merged with and into CRI, with CRI as the surviving corporation and a wholly owned subsidiary. Under the terms of the Merger 
Agreement, the Company paid approximately $257.2 million which consisted of cash of $168.8 million and approximately 6.4 million 
shares of the Company’s common stock. Of the consideration, $15.0 million in cash and approximately 1.3 million of the Company’s 
common stock were deposited into an escrow account until December 2012, subject to any claims, to fund any indemnification 
obligations to the Company following the consummation of the merger. In addition, as part of the requirements of the Merger 
Agreement, on June 7, 2011, the Company filed with the Securities and Exchange Commission a registration statement on Form S-3 
which registers the resale of the shares of common stock received by the former shareholders of CRI. The acquisition of CRI expands 
the Company’s technologies available for licensing with complementary technologies from CRI that include patented innovations and 
solutions for content protection, network security and anti-counterfeiting. Additionally, CRI is part of the NBG reportable segment. 

As part of the acquisition, the Company agreed to pay $50.0 million to certain CRI employees and contractors in cash or the 

Company’s common stock, at the Company’s option, over three years following June 3, 2011 (the “Retention Bonus”). The Retention 
Bonus will be paid in three installments of approximately $16.7 million on June 3, 2012, June 3, 2013, and June 3, 2014. The 
Retention Bonus payouts are subject to the condition of employment, and therefore, treated as compensation and expensed as incurred 
on a graded attribution basis. The portion of the Retention Bonus that is forfeited by employees that have left the Company prior to 
payout will be accelerated and the forfeited amount will be paid out to a designated charitable organization. The first payment will be 
made in cash and the following two payments will be made in either cash or shares of the Company’s common stock, at the 
Company’s option. 

The  acquisition  has  been  accounted  for  using  the  purchase  method  of  accounting  in  accordance  with  the  business  acquisition 
guidance. Under the purchase accounting method, the total estimated purchase consideration of the acquisitions was allocated to the 
tangible  and  identifiable  intangible  assets  acquired  and  liabilities  assumed  based  on  their  relative  fair  values.  The  excess  of  the 
purchase  consideration  over  the  net  tangible  and  identifiable  intangible  assets  acquired  and  liabilities  assumed  was  recorded  as 
goodwill.  The  purchase  price  allocation  has  been  finalized.  The  Company  expensed  the  related  transaction  costs  amounting  to 
approximately $3.9 million. The related transaction costs were recorded in the marketing, general and administrative expenses in the 
consolidated statements of operations.  

The following table summarizes the consideration paid by the Company (in thousands):

Total .......................................................................................................................................... 

  $  168,805 
88,438 
$  257,243 

The 6.4 million shares of common stock issued were valued based on the closing stock price at the date of the acquisition which 
amounted to $88.4 million. Approximately 161 thousand shares were used to satisfy tax withholding obligations, resulting in the net 
issuance of $86.1 million of common stock.  

The purchase price allocation for the business acquired is based on management’s estimate of the fair value for purchase accounting 

purposes at the date of acquisition. The fair value of the assets acquired has been determined primarily by using valuation methods 
that discount the expected future cash flows to present value using estimates and assumptions determined by management. The 
Company performed a valuation of the net assets acquired as of June 3, 2011 (the acquisition closing date). The purchase price from 
the business combination was allocated as follows:

The goodwill arising from the acquisition is primarily attributed to synergies related to the combination of new and complementary 

technologies of the Company and the assembled workforce of CRI. All of this goodwill is expected to be deductible for tax purposes.

  Estimated Useful 
Life 

The  favorable  contracts  are  acquired  patent  licensing  agreements  where  the  Company  has  no  performance  obligations.  Cash 
received from these acquired favorable contracts will reduce the favorable contract intangible asset. The estimated useful life is based 
on  expected  payment  dates  related  to  the  favorable  contracts.  The  group  of  purchased  intangible  assets  has  an  estimated  weighted 
average useful life of approximately 7 years from the date of acquisition.  

The fair value of the existing technology and customer relationships was determined based on an income approach using the 

discounted cash flow method. Discount rates of 30% and 26% were used to value the existing technology and customer relationships, 
respectively. The estimated discount rates were based on implied rate of return of the transaction, adjusted for specific risk profile of 
the asset. The remaining useful life for the existing technology was based on historical product development cycles, the projected rate 
of technology attrition, and the pattern of projected economic benefit of the asset. The remaining useful life of customer relationships 
was estimated based on customer attrition, new customer acquisition and future economic benefit of the asset. 

The fair value of the favorable contracts was determined based on an income approach using the discounted cash flow method with 

a discount rate of 9%. The favorable contracts will be reduced as cash is received from the customers. 

The fair value of the non-competition agreements were determined based on the income approach using the discounted cash flow 

method with a 26% discount rate. The estimated useful life was determined based on the future economic benefit expected to be 
received from the assets.  

The  CRI  business  combination  is  included  in  the  Company’s  “All  Other”  segment.  Additionally,  the  consolidated  financial 
statements include approximately $17.4 million of revenue and approximately $20.2 million of operating losses of CRI from the date 
of acquisition through December 31, 2011. 

The following unaudited pro forma financial information presents the combined results of operations for the Company and CRI as 
if the acquisition had occurred on January 1, 2010. The unaudited pro forma financial information has been prepared for comparative

Pro forma earnings for both periods in 2011 and 2010 were adjusted for certain acquisition-related costs. 

2010 Acquisition Activity:  During the year ended December 31, 2010, the Company entered into various business combinations 
and technology asset acquisitions. These transactions had a total purchase price of $27.7 million. These transactions were completed 
to acquire patents and technology for general lighting, LCD backlighting, microelectromechanical systems displays, other technology 
and  key  employees.  Direct  acquisition  costs  of  $0.3  million  related  to  the  business  combinations  were  expensed  as  incurred.  The 
allocation of the purchase price for these transactions was acquired intangible assets of $24.4 million, property, plant and equipment of 
$0.7 million and goodwill of $2.6 million. 

2009 Acquisition Activity:  During the year ended December 31, 2009, the Company entered into a business combination with GLT 
to acquire technology and a portfolio of advanced lighting and optoelectronics patents, which have applications, among other things, 
for the consumer electronic systems, automotive lighting systems and general lighting illumination for a total purchase price of $26.0 
million in cash. The Company incurred approximately $1.1 million in direct acquisition costs which were expensed as incurred. The 
allocation  of  the  purchase  price  for  these  transactions  was  acquired  developed  technology  of  $14.9  million  and  goodwill  of  $11.1 
million. In addition, the Company purchased patents related to other technologies of approximately $2.5 million. 

In  the  business  combinations,  the  fair  value  of  identifiable  intangible  assets  acquired  has  been  determined  primarily  by  using 
valuation  methods  that  discount  the  expected  future  cash  flows  to  present  value  using  estimates  and  assumptions  determined  by 
management. The business combinations were included in the NBG operating segment. The acquired developed technology intangible 
assets are amortized on a straight-line basis over the respective useful lives which range from 3 to 7 years. The consolidated financial 
statements  include  the  operating  results  of  each  business  combination  from  the  date  of  acquisition.  As  part  of  the  acquisitions,  the 
Company  has  entered  into  certain  compensatory  arrangements  where  payments  are  triggered  on  the  achievement  of  certain 
performance metrics and milestones which occur over future periods up to 20 years.  

19. Subsequent Event  

On  February  3,  2012,  the  Company  completed  its  acquisition  of  a  privately-held  company,  Unity  Semiconductor  Corporation 
(“Unity”), by acquiring all issued and outstanding common shares of Unity. Pursuant to the merger agreement on February 3, 2012, a 
merger sub merged with and into Unity as the surviving corporation and a wholly owned subsidiary. Under the terms of the merger 
agreement,  the  Company  paid  approximately  $35.0  million  in  cash,  subject  to  certain  adjustments.  Of  the  consideration, 
approximately  $5.3  million  in  cash  was  deposited  into  an  escrow  account  until  August  3,  2013,  subject  to  any  claims,  to  fund  any 
indemnification obligations to the Company following the consummation of the merger. The Company acquired Unity’s technology 
and a portfolio of memory semiconductor patents, which have applications, among other things. The Company incurred approximately 
$0.6 million in direct acquisition costs which were expensed as incurred.  

As part of the acquisition, the Company agreed to pay $5.0 million in retention bonuses to certain Unity employees and contractors. 
The retention bonus payouts are subject to the condition of employment, and therefore, will be treated as compensation and will be 
recorded as compensation expenses as incurred.    

The  acquisition  will  be  accounted  for  using  the  purchase  method  of  accounting  in  accordance  with  the  business  acquisition 
guidance. Under the purchase accounting method, the total estimated purchase consideration of the acquisition will be allocated to the 
tangible  and  identifiable  intangible  assets  acquired  and  liabilities  assumed  based  on  their  relative  fair  values.  The  excess  of  the 

113 

 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
purchase  consideration  over  the  net  tangible  and  identifiable  intangible  assets  acquired and  liabilities  will  be  recorded  as  goodwill. 
Due to the timing of the acquisition, the allocation of the purchase price has not been finalized.

PROXY STATEMENT 
FOR 
2012 ANNUAL MEETING OF STOCKHOLDERS 

INFORMATION CONCERNING SOLICITATION AND VOTING 

The enclosed proxy is solicited on behalf of the Board of Directors of Rambus Inc. (“Rambus” or 

“we,” “us” or the “Company”) for use at our 2012 Annual Meeting of Stockholders (the “Annual Meeting”) 
to be held on Thursday, April 26, 2012 at 9:00 a.m. local time, and at any postponement or adjournment of 
the meeting.  The purpose of the Annual Meeting is described in the accompanying Notice of Annual Meeting 
of Stockholders. 

The Annual Meeting will be held at the Santa Clara Marriott located at 2700 Mission College 

Boulevard, Santa Clara, California  95054. 

  Our principal executive offices are located at 1050 Enterprise Way, Suite 700, Sunnyvale, California 

94089; our telephone number is (408) 462-8000; and our internet address is www.rambus.com. 

These proxy solicitation materials and the enclosed Annual Report for the fiscal year ended 
December 31, 2011, including our Annual Report on Form 10-K for the year ended December 31, 2011 (the 
“Form 10-K”) were first mailed on or about March 15, 2012, to all stockholders entitled to vote at the 
meeting. 

GENERAL INFORMATION ABOUT THE MEETING 

Who May Attend 

You may attend the Annual Meeting if you owned your shares, either as a 
stockholder of record or as a beneficial owner as described below, as of the 
close of business on March 1, 2012 (the “Record Date”). 

Stockholders of Record 

If your shares are registered directly in your name, then you are considered 
to be the stockholder of record with respect to those shares, and we are 
sending these proxy materials directly to you.  To attend the meeting as a 
stockholder of record, please bring proper identification. 

Beneficial Owners 

If your shares are held in a stock brokerage account or by a bank or other 
nominee, you are considered the beneficial owner of shares held in “street 
name,” and your broker or nominee is forwarding these proxy materials to 
you.  Your broker or nominee is considered to be the stockholder of record 
with respect to those shares.  To attend the meeting as a beneficial owner, 
please bring proper identification and a statement from the broker, bank or 
other nominee holding your shares that confirms your beneficial 
ownership of the shares as of the Record Date. 

1 

 
 
 
 
Who May Vote 

You may vote at the Annual Meeting if you owned your shares, either as a 
stockholder of record or as a beneficial owner, as of the close of business 
on the Record Date.  As of that date, we had a total of 110,402,025 shares 
of common stock outstanding, which were held of record by 
approximately 689 stockholders.  You are entitled to one vote for each 
share of our common stock that you own. 

As of the Record Date, we had no shares of preferred stock outstanding. 

Voting Your Proxy 

Stockholders of Record 

If you hold your shares in your own name as a holder of record, you may 
instruct the proxy holders how to vote your common stock by: 

  voting via the internet at www.proxyvote.com; 

  voting by telephone at 1-800-690-6903; or 

 

signing, dating and mailing the proxy card in the postage-paid 
envelope that we have provided. 

Even if you vote your shares by proxy, you may also choose to attend the 
meeting and vote your shares in person.  If you provide instructions in 
your completed proxy card, the proxy holders will vote your shares in 
accordance with those instructions.  If you sign and return a proxy card 
without giving specific voting instructions, your shares will be voted 
“FOR” all of the proposals described herein. 

Beneficial Owners 

If you are the beneficial owner of shares held in street name, you have the 
right to direct your broker how to vote.  Your broker or nominee has 
enclosed with these materials or provided voting instructions for you to 
use in directing the broker or nominee how to vote your shares. 

You are invited to attend the meeting and vote your shares in person at the 
meeting.  However, since you are not the stockholder of record, you must 
obtain and bring with you to the meeting a “legal proxy” from the broker, 
bank or other nominee holding your shares that confirms your beneficial 
ownership of the shares and gives you the right to vote your shares at the 
meeting. 

We are not aware of any matters to be presented at the Annual Meeting 
other than those described in this Proxy Statement.  If any matters not 
described in this Proxy Statement are properly presented at the meeting, 
the proxy holders will use their own judgment to determine how to vote 
your shares.  If the meeting is adjourned or postponed, the proxy holders 
can vote your shares on the new meeting date as well, unless you have 

2 

Discretionary Voting 
Power; Matters to be 
Presented 

 
 
subsequently revoked your proxy. 

Changing Your Vote 

Stockholders of Record 

If you would like to change your vote you can do so in the following ways: 

  deliver written notice of your revocation to our corporate 

Secretary prior to the Annual Meeting; 

  deliver a properly executed, later dated proxy prior to the Annual 

Meeting; or 

 

attend the Annual Meeting and vote in person. 

Please note that your attendance at the meeting in and of itself is not 
enough to revoke your proxy. 

Beneficial Owners 

If you instructed a broker or nominee to vote your shares following the 
directions originally included with these materials or provided to you, you 
can change your vote only by following your broker or nominee’s 
directions for doing so.  You can only change your vote at the Annual 
Meeting if you have obtained a “legal proxy” from the broker, bank or 
other nominee holding your shares that confirms your beneficial 
ownership of the shares and gives you the right to vote your shares at the 
meeting. 

We will bear the cost of this proxy solicitation.  In addition to soliciting 
proxies by mail, our directors, officers and employees may solicit proxies 
in person or by telephone.  None of these individuals will receive any 
additional or special compensation for doing this, but they may be 
reimbursed for reasonable out-of-pocket expenses.  We have also hired 
Morrow & Co., LLC to help us solicit proxies from brokers, bank 
nominees and other institutional owners.  We expect to pay Morrow & 
Co., LLC a fee of up to approximately $28,500 for its services, and we will 
reimburse certain out-of-pocket expenses. 

The Annual Meeting will be held if a majority of our outstanding shares of 
common stock entitled to vote at the meeting are represented in person or 
by proxy. 

When proxies are properly dated, executed and returned, the shares 
represented by such proxies will be voted at the Annual Meeting in 
accordance with the directions of the stockholder.  However, if no specific 
instructions are given, the shares will be voted in accordance with the 
following recommendations of our Board of Directors:

“FOR” the election of J. Thomas Bentley, Sunlin Chou, Ph.D., 
Harold Hughes and Abraham D. Sofaer as Class I directors; 

 “FOR” the approval of named executive officer compensation, as 
disclosed in this Proxy Statement; 

“FOR” the amendment to our 2006 Equity Incentive Plan to 
increase the number of shares of common stock reserved for 
issuance under such plan by 6,500,000 shares; 

“FOR” the amendment to our 2006 Employee Stock Purchase Plan 
to increase the number of shares of common stock reserved for 
issuance under such plan by 1,500,000 shares; 

“FOR” the approval of a one-time stock option exchange program; 
and 

“FOR” the ratification of PricewaterhouseCoopers LLP as our 
independent registered public accounting firm for the fiscal year 
ending December 31, 2012. 

Abstentions, Withheld, and 
Broker Non-Votes 

We treat shares that are voted “WITHHELD” or “ABSTAIN” in person or 
by proxy as being: 

  present for purposes of determining whether or not a quorum is 

present at the Annual Meeting; and 

 

entitled to vote on a particular subject matter at the Annual 
Meeting. 

In the election of directors, any vote you make that is a “WITHHELD” or 
“ABSTAIN” for any nominee will not impact the election of that nominee.  
In tabulating the voting results for the election of directors, only “FOR” 
and “AGAINST” votes are counted. 

For the other proposals, a “WITHHELD” or “ABSTAIN” vote is the same 
as voting against the proposal. 

If you hold your common stock through a broker, the broker may be 
prevented from voting shares held in your brokerage account on some 
proposals (a “broker non-vote”) unless you have given the broker voting 
instructions.  Thus, if you hold your common stock through a broker, it is 
critical that you cast your vote if you want it to count.  If you hold your 
common stock through a broker and you do not instruct your broker how 
to vote on Proposals One, Two, Three, Four and Five, it will be considered 
a broker non-vote and no votes will be cast on your behalf with respect to 
such Proposal(s).  Shares that are subject to a broker non-vote are counted 

4 

 
 
for purposes of determining whether a quorum exists but do not count for 
or against any particular proposal. 

Your broker will continue to have discretion to vote any uninstructed 
shares on Proposal Six, the Ratification of the Appointment of the 
Company’s Independent Registered Public Accounting Firm. 

Deadline for Receipt of 
Stockholder Proposals 

Stockholders may present proposals for action at a future annual meeting 
only if they comply with the requirements of our bylaws and the proxy 
rules established by the Securities and Exchange Commission (“SEC”).  

Stockholder proposals, including nominations for the election of directors, 
which are intended to be presented by such stockholders at our 2013 
Annual Meeting of Stockholders must be received by us no later than 
November 18, 2012 to be considered for inclusion in the proxy statement 
and proxy card relating to that meeting. 

In addition to the SEC rules, our bylaws establish an advance notice 
procedure for proposals that a stockholder wants to have included in our 
proxy statement relating to a meeting or to have brought before the 
meeting.  Generally for these proposals, including the nomination of a 
person for director, a stockholder must provide written notice to our 
corporate Secretary at least 90 days in advance of the meeting.  However, 
in the event that less than 100 days notice or prior public disclosure of the 
date of the meeting is given or made to stockholders, notice by the 
stockholder to be timely must be received not later than the close of 
business on the tenth day following the day on which such notice of the 
date of the meeting was mailed or such public disclosure was made. 

Moreover, your notice must contain specific information concerning the 
matters to be brought before the meeting.  We urge you to read our bylaws 
in full in order to understand the requirements of bringing a proposal or 
nomination. 

A copy of the full text of the bylaw provision relating to our advance 
notice procedure may be obtained by writing to our corporate Secretary or 
by accessing a copy of our bylaws, which are publicly available at 
http://www.sec.gov.  All notices of proposals by stockholders, whether or 
not included in proxy materials, should be sent to Rambus Inc., 1050 
Enterprise Way, Suite 700, Sunnyvale, California 94089, Attention: 
Secretary. 

Our Board of Directors may be contacted by writing to them via regular 
mail at Board of Directors, Rambus Inc., 1050 Enterprise Way, Suite 700, 
Sunnyvale, California 94089.  If you wish to contact our Board of 
Directors or any member of the Audit Committee to report questionable 
accounting or auditing matters you may do so anonymously by using this 
mailing address and designating the communication as “confidential.” 

5 

Communication With the 
Board of Directors 

 
 
Our process for handling communications to our Board of Directors is as 
follows: 

Any stockholder communications that our Board of Directors receives will 
first go to our Secretary/General Counsel, who will log the date of receipt 
of the communication as well as (for non-confidential communications) 
the identity of the correspondent in our stockholder communications log. 

Unless the communication is marked “confidential,” our Secretary/General 
Counsel will review, summarize and, if appropriate, draft a response to the 
communication in a timely manner.  The summary and response will be in 
the form of a memo, which will become part of the stockholder 
communications log that our Secretary/General Counsel maintains with 
respect to all stockholder communications. 

Our Secretary/General Counsel will then forward the original stockholder 
communication along with the memo to the member(s) of our Board of 
Directors (or committee chair if the communication is addressed to a 
committee) for review. 

Any stockholder communication marked “confidential” will be logged by 
our Secretary/General Counsel as “received” but will not be reviewed, 
opened or otherwise held by our Secretary/General Counsel.  Such 
confidential correspondence will be immediately forwarded to the 
addressee(s) without a memo or any other comment by our 
Secretary/General Counsel. 

Annual Meeting Attendance  Members of our Board of Directors are invited but not required to attend 

“Householding” of Proxy 
Materials 

the Annual Meeting of Stockholders.  The 2011 Annual Meeting of 
Stockholders was attended by the following members of our Board of 
Directors: Ms. Herscher and Messrs. Chou, Dunlevie, Hughes, Shrigley, 
Sofaer and Stang. 

The SEC has adopted rules that permit companies and intermediaries such 
as brokers to satisfy delivery requirements for proxy statements with 
respect to two or more stockholders sharing the same address by delivering 
a single proxy statement addressed to those stockholders.  This process, 
which is commonly referred to as “householding,” potentially provides 
extra convenience for stockholders and cost savings for companies.  The 
Company and some brokers household proxy materials, delivering a single 
proxy.  If your proxy statement is being householded and you would like 
to receive separate copies, or if you are receiving multiple copies and 
would like to receive a single copy, please contact Investor Relations at 
Rambus Inc., 1050 Enterprise Way, Suite 700, Sunnyvale, California 
94089, Attention: Secretary, or ir@rambus.com, or place a collect call to 
the Company, at (408) 462-8000, and direct the call to the Investor 
Relations Department.

Delivery of Proxy Materials  To receive current and future proxy materials, such as annual reports, 
proxy statements and proxy cards, in either paper or electronic form, 
please contact Investor Relations at ir@rambus.com or

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS  
FOR THE ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON APRIL 26, 2012 

The Notice and Proxy Statement, Annual Report to Shareholders and 10-K Combo  
document are available at www.proxyvote.com. 

PROPOSAL ONE: 
ELECTION OF DIRECTORS 

Our Board of Directors is currently composed of eight members who are divided into two classes 

with overlapping two-year terms.  As of the date of this proxy statement, we have four Class I directors and 
four Class II directors, as noted under “Nominees” below.  At each annual meeting of stockholders, a class of 
directors is elected for a term of two years to succeed those directors whose terms expire on the annual 
meeting date.  A director serves in office until his or her respective successor is duly elected and qualified or 
until his or her death or resignation.  Any additional directorships resulting from an increase in the number of 
directors will be distributed among the two classes so that, as nearly as possible, each class will consist of an 
equal number of directors.  Any vacancy occurring mid-term will be filled by a person selected by a majority 
of the other current members of the Board of Directors.  There is no family relationship between any of our 
directors. 

Nominees 

Four Class I directors are to be elected at the Annual Meeting for a two-
year term ending in 2014. Based upon the recommendation of our 
Corporate Governance/Nominating Committee, our Board has nominated: 
J. Thomas Bentley, Sunlin Chou, Ph.D., Harold Hughes and Abraham D. 
Sofaer for election as Class I directors. 

If any of J. Thomas Bentley, Sunlin Chou, Ph.D., Harold Hughes or 
Abraham D. Sofaer is unable or declines to serve as a director at the time 
of the Annual Meeting, proxies will be voted for a substitute nominee or 
nominees designated by the Board of Directors. 

Mr. Bentley was previously a Class II director.  Due to the departure of 
two directors in 2011, Mr. Bentley and the Board of Directors have 
decided that effective the date of the filing of this proxy statement, Mr. 
Bentley will become a Class I director and will stand for reelection at the 
Annual Meeting.

Vote Required 

Information About 
Nominees and Other 
Directors 

The Company's bylaws require that each director be elected by the 
majority of votes cast with respect to such director in uncontested 
elections. The Board of Directors, after taking into consideration the 
recommendation of the Corporate Governance and Nominating Committee 
of the Board, will determine whether or not to accept the pre-tendered 
resignation of any nominee for director, in an uncontested election, who 
receives a greater number of votes "AGAINST" his or her election than 
votes "FOR" such election.  There are no cumulative voting rights in the 
election of directors.  Stockholders as of the Record Date may vote their 
shares for or against some, all or none of the Class I nominees. 

The members of our Board of Directors have deep executive and board 
leadership experience derived from their respective tenures as executives 
and directors of technology companies of various sizes.  The following 
table contains information regarding the Class I nominees and other 
directors as of March 1, 2012.  This information includes the specific 
experience, qualifications, attributes and skills that led to the Board of 
Directors’ conclusion that the person should serve as a director.

has served as Chairperson of the Board since June 2011.  He

Mr. Bentley’s financial expertise and years of business and 
leadership experience, including fifteen years as a co-founder

guidance to us and led the Board of Directors to conclude that 
he should serve as a director.  In addition, our Board of 
Directors’ determination that Mr. Bentley is the Audit 
Committee “financial expert” lends further support to his 
financial acumen and qualifications for serving on our Board

E.E. in Electrical Engineering from Massachusetts Institute of 
Technology and received a Ph.D. in Electrical Engineering 
from Stanford University.  Dr. Chou serves on the board of 
several non-profit institutions. 

During his career, Dr. Chou organized and led research and 
development teams to innovate rapidly and continuously in 
order to maintain technological leadership.  Dr. Chou’s 
understanding of the technical, organizational and strategic 
business aspects of the semiconductor integrated circuit 
industry led the Board of Directors to conclude that he should 
serve as a director. 

Harold Hughes ....................................   66  Mr. Hughes has served as our chief executive officer and 
president since January 2005 and as a director since June 
2003.  He served as a United States Army Officer from 1969

Corporation.  Mr. Hughes held a variety of positions within 
Intel Corporation from 1974 to 1997, including treasurer, vice 
president of Intel Capital, chief financial officer, and vice 
president of Planning and Logistics.  Following his tenure at 
Intel, Mr. Hughes was the chairman and chief executive 
officer of Pandesic, LLC.  He holds a B.A. from the 
University of Wisconsin and an M.B.A. from the University 
of Michigan.  In the past five years, he has served as a 
director of Berkeley Technology, Ltd. and a private company. 

Mr. Hughes’ seven-year tenure as our Chief Executive 
Officer, his prior leadership experience at Intel Corporation 
and his ability to provide deep and valuable operational and 
strategic insight to the Board of Directors led the Board of 
Directors to conclude that he should serve as a director.  The 
Company has begun a search for a successor to Mr. Hughes 
who is planning to retire from his current position; however, 
Mr. Hughes will continue in his position as chief executive 
officer until a successor is named. 

Abraham D. Sofaer .............................   73  Mr. Sofaer has served as a director since May 2005.  He has

Brennan, Jr. on the U.S. Supreme Court.  In the past five 
years, Mr. Sofaer has served as a director of  Gen-Probe, Inc. 
and several private companies and non-profit institutions. 

Mr. Sofaer’s extensive and varied experience in legal affairs 
allows him to assist us with the complex legal challenges we 
face and led the Board of Directors to conclude that he should 
serve as a director.  He has brought a unique legal and 
strategic perspective to us and rendered specific contributions 
by serving on the Special Litigation Committee that helped us 
deal with the options backdating matter, and by leading the 
settlement negotiation of the shareholder action stemming 
from the same affair.  Until the appointment of our present 
General Counsel, he served as the Chair of the Committee on 
Legal Affairs, which helped formulate policy and strategy in 
defense of legal challenges.  In addition, his experience in 
government and public policy has enabled him to serve as a 
valuable member of our Audit Committee and Corporate 
Governance/Nominating Committee. 

The Board unanimously recommends that you vote “FOR” the election to the Board of 

Directors of each of the nominees proposed above.

Board of Directors 
Meetings and Committees 

Our Board of Directors held a total of nine meetings during 2011.  During 
2011, each member of our Board of Directors attended 75% or more of the 
meetings of the Board of Directors and of the committees, if any, of which 
she or he was a member. 

Director Independence 

Director Qualifications 

Our Board of Directors has determined that each of the following 
directors, constituting a majority of our Board of Directors, has no material 
relationship with us (either directly as a partner, stockholder or officer of 
an organization that has a relationship with us) and is “independent” as 
defined under Nasdaq Rule 5605 and the applicable rules promulgated by 
the SEC:  J. Thomas Bentley, Sunlin Chou,  P. Michael Farmwald, 
Penelope A. Herscher, David Shrigley, Abraham D. Sofaer and Eric Stang.  

Each of the committees of our Board of Directors is composed of 
independent directors as follows: 

Audit Committee: 

Eric Stang (Chair) 
J. Thomas Bentley 
P. Michael Farmwald 

Compensation 
Committee: 

Penelope A. Herscher (Chair) 
David Shrigley 
Abraham D. Sofaer 

Corporate Governance/ 
Nominating 
Committee: 

Sunlin Chou (Chair) 
David Shrigley 
Abraham D. Sofaer 

Except as may be required by rules promulgated by Nasdaq or the SEC, 
there are currently no specific, minimum qualifications that must be met 
by each candidate for our Board of Directors, nor are there any specific 
qualities or skills that are necessary for one or more of the members of our 
Board of Directors to possess.  The Corporate Governance/Nominating 
Committee considers a number of factors in its assessment of the 
appropriate skills and characteristics of members of the Board of 
Directors, as well as the composition of the Board of Directors as a whole.  
These factors include the members’ qualification as independent, as well 
as consideration of judgment, character, integrity, diversity, skills, and 
experience in such areas as operations, technology, finance, and the 
general needs of the Board of Directors and such other factors as the 
Corporate Governance/Nominating Committee may consider appropriate.  
The Corporate Governance/Nominating Committee does not have a formal 
policy with respect to diversity.  However, the Board of Directors and the 
Corporate Governance/Nominating Committee believe that it is essential 
that the members of the Board of Directors represent diverse viewpoints.  
In considering candidates for the Board of Directors, the Board of 
Directors and the Corporate Governance/Nominating Committee consider 
the entirety of each candidate’s credentials in the context of the factors 
mentioned above.

Corporate Governance 
Principles 

Section 16(a) Beneficial 
Ownership Reporting 
Compliance 

We are committed to maintaining the highest standards of business 
conduct and corporate governance, which we believe are essential to 
running our business efficiently, serving our stockholders well and 
maintaining our integrity in the marketplace.  We have adopted a code of 
business conduct and ethics for directors, officers, and employees known 
as the Code of Business Conduct and Ethics, which is available on our 
website at 
http://investor.rambus.com/documentdisplay.cfm?DocumentID=5115. 

Section 16(a) of the Securities Exchange Act requires our executive 
officers, directors and ten percent stockholders to file reports of ownership 
and changes in ownership with the SEC.  The same persons are required to 
furnish us with copies of all Section 16(a) forms they file.  Based on our 
review of these forms, we believe that during fiscal 2011 all of our 
executive officers, directors and ten percent stockholders complied with 
the applicable filing requirements. 

Executive Sessions of the 
Independent Directors 

It is the policy of the Board of Directors to have executive sessions of the 
independent directors at which only independent directors are present, 
typically in conjunction with the regularly scheduled meetings of the 
Board of Directors. 

Committees of the Board of 
Directors 

During 2011, our Board of Directors had three standing committees: 

Audit Committee 

 

 

 

an Audit Committee, 

a Compensation Committee and 

a Corporate Governance/Nominating Committee. 

The following describes each committee, its function, its membership, and 
the number of meetings held during 2011. 

Each of the committees operates under a written charter adopted by our 
Board of Directors.  All of the current committee charters are available on 
our website at http://investor.rambus.com/documents.cfm. 

Currently, the Audit Committee is composed of Eric Stang, J. Thomas 
Bentley and P. Michael Farmwald, with Mr. Stang serving as Chair.  The 
Audit Committee oversees our corporate accounting and financial 
reporting processes and internal control over financial reporting, as well as 
our internal and external audits.  The Audit Committee held eight meetings 
during 2011.  Its duties include: 

  Reviewing our accounting and financial reporting processes and 

internal control over financial reporting; 

  Providing oversight and review at least annually of our risk 
management policies, including our investment policy;

  Reviewing the plans, findings and performance of our internal 

auditors; 

  Reviewing our annual and quarterly financial statements and 

related disclosure documents; and 

  Overseeing special investigations into financial and other matters, 

as necessary. 

Our Board of Directors has determined that Mr. Bentley is the Audit 
Committee “financial expert” and that Mr. Bentley, together with each of 
Mr. Stang and Dr. Farmwald, has no material relationship with us (either 
directly as a partner, stockholder or officer of an organization that has a 
relationship with us) and is an “independent director” as defined under 
Nasdaq Rule 5605 and the applicable rules promulgated by the SEC. 

The Audit Committee’s role is detailed in the Audit Committee Charter 
and is available on our website at 
http://investor.rambus.com/documentdisplay.cfm?DocumentID=5108. 

Currently, the Compensation Committee is composed of Penelope A. 
Herscher, David Shrigley and Abraham D. Sofaer, with Ms. Herscher 
serving as Chair.  All members of the Compensation Committee are non-
employee, outside directors.  The Compensation Committee reviews and 
determines all forms of compensation to be provided to our executive 
officers, including the named executive officers and directors of Rambus, 
including base compensation, bonuses, and stock compensation.  The 
Compensation Committee held nine meetings during 2011.  Its duties 
include: 

  Annually review and approve the Chief Executive Officer 

(“CEO”) and other executive officers’ compensation in the context 
of their performance, which includes reviewing and approving 
their annual base salary, annual incentive bonus, including the 
specific goals, targets, and amounts, equity compensation, and any 
employment agreements, and any other benefits, compensation or 
arrangements, as applicable; 

  Administer our stock option and equity incentive plans pursuant to 
the terms of such plans and the authority delegated by our Board 
of Directors, including: granting stock options, stock appreciation 
rights, restricted stock, restricted stock units or other equity 
compensation to individuals eligible for such grants and amend 
such awards following their grant; amending the plans; and 
delegating to appropriate executive officers of the Company the 
ability to grant awards to non-executive officer employees of the

evaluation of CEO or executive officer or director compensation, 
and approve the consultant’s fees and other terms of service, as 
well as obtain advice and assistance from internal or external 
legal, accounting or other advisors; and 

  Conduct an annual assessment of the Company’s engagement with 

compensation consultants retained by the Board and/or 
management, as applicable, including the nature and extent of 
services provided, the amount of fees paid and who made or 
recommended the decision to retain the compensation consultants. 

The Compensation Committee uses Semler Brossy Consulting Group, 
LLC (SBCG) to assist in evaluating executive and director compensation. 

A detailed description of the processes and procedures of the 
Compensation Committee for considering and determining executive and 
director compensation, including the role of SBCG, is provided in the 
“Executive Compensation” section of this proxy statement. 

The Compensation Committee’s role is detailed in the Compensation 
Committee Charter, which is available on our website at

Corporate 
Governance/Nominating 
Committee 

Currently, the Corporate Governance/Nominating Committee is composed 
of Sunlin Chou, David Shrigley and Abraham D. Sofaer, with Dr. Chou 
serving as Chair.  The Corporate Governance/Nominating Committee held 
six meetings during 2011. 

The Corporate Governance/Nominating Committee recommends and 
approves Rambus’ Corporate Governance Guidelines.  Its duties include: 

  Evaluating and making recommendations to the Board of 

Directors concerning the appointment of directors to committees 
of the Board of Directors and the selection of committee chairs; 



Identifying and Evaluating 
Nominees For Directors 

Consideration of 
Stockholder Nominees to 
the Board 

  Overseeing the evaluation of the Board of Directors; and 

  Proposing the slate of nominees for election to the Board of 

Directors. 

The Corporate Governance/Nominating Committee’s role is detailed in the 
Corporate Governance/Nominating Committee Charter which is available 
on our website at 
http://investor.rambus.com/documentdisplay.cfm?DocumentID=5110. 

The Corporate Governance/Nominating Committee utilizes a variety of 
methods for identifying and evaluating nominees for director, including 
those discussed in the “Director Qualifications” section of this proxy 
statement.  In the event that vacancies on the Board of Directors are 
anticipated, or otherwise arise, the committee will consider various 
potential candidates for director.  Candidates may come to the attention of 
the committee through current members of the Board of Directors, 
professional search firms, stockholders or other persons.  The Corporate 
Governance/Nominating Committee has from time to time retained third 
parties to whom a fee is paid to assist it in identifying or evaluating 
potential director nominees. 

It is the policy of the Corporate Governance/Nominating Committee to 
consider nominees recommended by stockholders for election to our Board 
of Directors.  Stockholder recommendations for candidates to our Board of 
Directors must be directed in writing to Rambus Inc., 1050 Enterprise  
Way, Suite 700, Sunnyvale, CA 94089 Attention: Secretary, and must 
include: the candidate’s name, age, business address and residence 
address; the candidate’s principal occupation or employment; the number 
of shares of the Company which are beneficially owned by such candidate; 
a description of all arrangements or understandings between the 
stockholder making such nomination and any other person or persons 
(naming such person or persons) pursuant to which the nominations are to 
be made by the stockholder; detailed biographical data and qualifications; 
information regarding any relationships between the candidate and the 
Company within the last three years; any other information relating to such 
nominee that is required to be disclosed in solicitations of proxies for 
elections of directors, or is otherwise required, in each case pursuant to 
Regulation 14A under the Securities Exchange Act of 1934, as amended.  
A stockholder’s recommendation to the Secretary must also set forth: the 
name and address, as they appear on the Company’s books, of the 
stockholder making such recommendation; the class and number of shares 
of the Company which are beneficially owned by the stockholder and the 
date such shares were acquired by the stockholder; any material interest of 
the stockholder in such nomination; any other information that is required 
to be provided by the stockholder pursuant to Regulation 14A under the 
Securities Exchange Act of 1934, as amended, in his capacity as a 
proponent to a stockholder proposal; and a statement from the 
recommending stockholder in support of the candidate, references for the 
candidate, and an indication of the candidate’s willingness to serve, if

Board Leadership 
Structure and Role in Risk 
Oversight  

elected. 

Our Corporate Governance Guidelines require that the Chairperson of the 
Board not be the CEO of the Company.  In addition, while the Chairperson 
works closely with the CEO and other members of our management, the 
Chairperson is not part of management and does not have an operating or 
external role or responsibility.  The Board of Directors considers it useful 
and appropriate to designate a Chairperson to act as the presiding director 
at Board of Directors meetings, to call and organize such meetings and 
manage the agenda thereof, and to manage the affairs of the Board of 
Directors, including ensuring that the Board of Directors is organized 
properly, functions effectively, and meets its obligations and 
responsibilities. The Chairperson also acts as the principal contact for the 
CEO and other members of the Board of Directors and management, as 
appropriate, for matters requiring the attention of the full Board of 
Directors. We believe that this leadership structure is appropriate given the 
attention, time, effort, and energy that the CEO is required to dedicate to 
his position in the current business environment, and the high level of 
commitment required to serve as our Chairperson. 

The Board of Directors plays an integral role in our risk oversight 
processes.  The Board of Directors meets regularly to receive reports from 
its committees, as well as from management with respect to areas of 
material risk to the Company, including legal, operational, financial and 
strategic risks.  In addition, the Audit Committee oversees and reviews at 
least annually our risk management policies, including our investment 
policies.   

Transactions with Related 
Persons 

None.   

Review, Approval or 
Ratification of Transactions 
with Related Persons 

Our directors and executive officers are subject to our Code of Business 
Conduct and Ethics, and our directors are guided in their duties by our 
Corporate Governance Guidelines.  Our Code of Business Conduct and 
Ethics requires that our directors and executive officers avoid situations 
where a conflict of interest might occur or appear to occur.  In general, our 
directors and executive officers should not have a pecuniary interest in 
transactions involving us or a customer, licensee, or supplier of us, unless 
such interest is solely a result of routine investments made by the 
individual in publicly traded companies. 

In the event that a director or executive officer is going to enter into a 
related party transaction with a relative or significant other, or with a 
business in which a relative or significant other is associated in any 
significant role, the director or executive officer must fully disclose the 
nature of the related party transaction to our Chief Financial Officer.  For 
directors and executive officers, such related party transaction then must 
be reviewed and approved in advance by the Audit Committee.  For other 
conflicts of interest that may arise, the Code of Business Conduct and 
Ethics advises our directors and executive officers to consult with our 
General Counsel. 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-6- 

 
 
In addition, each director and officer is required to complete a Director and 
Officer Questionnaire on an annual basis and upon any new appointment, 
which requires disclosure of any related-party transactions pertaining to 
the director or executive officer.  Our Board of Directors will consider 
such information in its determinations of independence with respect to our 
directors under Nasdaq Rule 5605 and the applicable rules promulgated by 
the SEC.

PROPOSAL TWO: 
ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION 

We are asking our stockholders to provide an advisory vote to approve the compensation of our named 

executive officers, including the Compensation Discussion and Analysis, the compensation tables and 
narrative disclosures as described in this Proxy Statement. This proposal, commonly known as a “say-on-pay” 
proposal, gives our stockholders the opportunity to express their views on the compensation of our named 
executive officers. 

 Please see the Compensation Discussion and Analysis section of this Proxy Statement on page 57, the 
compensation tables and the narrative disclosures that accompany the compensation tables for greater detail 
about our executive compensation programs, including information about the fiscal year 2011 compensation 
of our named executive officers. 

Recommendation 

We believe that our overall compensation program and philosophy support and help drive the 

Company’s long-term value creation, business strategy and operating performance objectives. We ask you to 
indicate your support for the compensation of our named executive officers as described in the Compensation 
Discussion and Analysis, the compensation tables and the narrative disclosures set forth in this Proxy 
Statement. 

While this say-on-pay vote is advisory and does not bind the Company to any particular action, the 
Board of Directors and the Compensation Committee value your opinion. Accordingly, the Board of Directors 
and the Compensation Committee will consider the outcome of this vote when making future compensation 
decisions for the Company’s named executive officers.  

The Board unanimously recommends a vote “FOR” the approval of the compensation of our 

named executive officers, as disclosed in this Proxy Statement.

PROPOSAL THREE: 
 APPROVAL OF THE AMENDMENT TO THE 2006 EQUITY INCENTIVE PLAN 

The  stockholders  are  being  asked  to  approve  an  amendment  to  our  2006  Equity  Incentive  Plan  (the 
“Incentive  Plan”)  to  add  6,500,000 shares  to  the  total  number  of  shares  reserved  for  issuance  under  the 
Incentive  Plan.  Our  Board  of  Directors  has  approved  the  increase  in  the  number  of  shares  reserved  for 
issuance  under  the  Incentive  Plan,  subject  to  approval  from  stockholders  at  the  Annual  Meeting.  If 
stockholders do not approve the amendment to the Incentive Plan, no shares will be added to the total number 
of shares reserved for issuance under the Incentive Plan. 

Our named executive officers and directors have an interest in this proposal as they are eligible to receive 

equity awards under the Incentive Plan. 

Our  Board  of  Directors  believes  that  long-term  incentive  compensation  programs  align  the  interests  of 
management, employees and the stockholders to create long-term stockholder value. Our Board of Directors 
believes that plans such as the Incentive Plan increase our ability to achieve this objective, especially, in the 
case of the Incentive Plan, by allowing for several different forms of long-term incentive awards, which our 
Board of Directors believes is critical for us to recruit, reward, motivate and retain talented personnel. Given 
the highly competitive labor market for employee talent, our Board of Directors and management believe that 
the ability to continue to grant equity awards will be critical to the future success of Rambus. 

Our  Board  of  Directors  believes  that  approval  of  the  amendment  will  enable  us  to  continue  to  use  the 
Incentive Plan to achieve employee performance, recruiting, retention and incentive goals. In particular, our 
Board  of  Directors  believes  that  our  employees  are  our  most  valuable  assets  and  that  the  awards  permitted 
under the Incentive Plan are vital to our ability to attract and retain outstanding and highly skilled individuals 
in the extremely competitive labor markets in which we compete. Such awards also are crucial to our ability 
to motivate employees to achieve our goals. 

Key Features of the Amended 2006 Equity Incentive Plan and Compensation Practices: 

  Proposed authorization of 6,500,000 additional shares under the Incentive Plan. 

  The Incentive Plan has a 1.5:1 conversion ratio for full-value awards. 

  An independent committee administers the Incentive Plan. 

  Restricted Stock, Restricted Stock Units, Performance Units, and Performance Shares vest ratably over a 

3-year period. 

  The Incentive Plan prohibits reprcing of outstanding awards without stockholder approval, which includes 

the substitution or exchange of new awards. 

  We have minimum stock ownership guidelines for our NEOs, senior executives and Board of Directors. 

  All employees are prohibited from hedging transactions involving Rambus stock. 

  Our NEOs are not entitled to any perquisites that are not generally available to employees. 

Vote Required; Recommendation of the  Approval  of  the  Amendment  to  the  Incentive  Plan  requires  the

Summary  of  the  2006  Equity  Incentive 
Plan  

Number of Shares of Common Stock 
Available Under the Incentive Plan  

affirmative vote of a majority of the shares of our Common Stock 
that  are  present  in  person  or  proxy  and  entitled  to  vote  at  the 
Annual Meeting.  

Our Board of Directors recommends that you vote “FOR” the 
Amendment  to  the  2006  Equity  Incentive  Plan  and  the 
increase  to  the  number  of  shares  reserved  for  issuance 
thereunder.  

The  following  is  a  summary  of  the  principal  features  of  the 
Incentive  Plan  and  its  operation.  The  summary  is  qualified  in  its 
entirety  by  reference  to  the  Incentive  Plan,  as  amended  giving 
effect to this Proposal Three, set forth in Appendix A.  

The Incentive Plan provides for the grant of the following types of 
incentive awards:  

•  stock options  

•  stock appreciation rights  

•  restricted stock  

•  restricted stock units  

•  performance shares and performance units  

•  other stock or cash awards  

Each  of  these  is  referred  to  individually  as  an  “Award.”  Those 
who  are  eligible  for  Awards  under  the  Incentive  Plan  include 
employees, directors and consultants who provide services to the 
Company  and  its  affiliates.  As  of  March  1,  2012,  approximately 
500 employees,  directors  and  consultants  would  be  eligible  to 
participate in the Incentive Plan.  

If stockholders approve Proposal 3, an additional 6,500,000 shares 
of  the  Company’s  Common  Stock  will  be  reserved  for  issuance 
under  the  Incentive  Plan.  As  of  March  1,  2012,  10.9  million 
shares  were  subject  to  outstanding  options  granted  under  the 
Incentive Plan, with a weighted average exercise price of $16.38 
per share and weighted average remaining term of 7.48 years, and 
1.0 million shares were subject to outstanding RSUs granted and 
unvested  under  the  Incentive  Plan.  0.3  million shares  remained 
available for any new Awards to be granted in the future. Shares 
subject  to  Awards  (excluding  stock  options)  granted  with  an 
exercise price less than the fair market value on the date of grant 
count  against  the  share  reserve  as  1.5 shares  for  every  one  share 
subject  to  such  an  Award.  To  the  extent  that  a  share  that  was 
subject  to  an  Award  that  counted  as  1.5 shares  against  the 
Incentive  Plan  reserve  pursuant  to  the  preceding  sentence  is

returned to the Incentive Plan, the Incentive Plan reserve will be 
credited  with  1.5 shares  that  will  thereafter  be  available  for 
issuance under the Incentive Plan.  

If  an  Award  expires  or  becomes  unexercisable  without  having 
been  exercised  in  full,  or,  with  respect  to  full  value  awards,  is 
forfeited to or repurchased by the Company, the unpurchased (or 
forfeited or repurchased, as applicable) shares that were subject to 
the Award will become available for future grant or sale under the 
Incentive Plan. Upon exercise of a stock appreciation right settled 
in shares, the gross number of shares covered by the portion of the 
Award  that  is  exercised  will  cease  to  be  available  under  the 
Incentive  Plan.  Shares  that  have  been  issued  under  the  Incentive 
Plan under any Award will not be returned to or become available 
for  future  distribution  under  the  Incentive  Plan;  provided, 
however,  that  if  unvested  shares  of  any  full  value  awards  are 
repurchased  by  the  Company  or  are  forfeited  to  the  Company, 
those  shares  will  become  available  for  future  grant  under  the 
Incentive Plan. Shares used to pay the exercise or purchase price 
of  an  Award  and/or  to  satisfy  the  tax  withholding  obligations 
related to an Award will not become available for future grant or 
sale under the Incentive Plan. To the extent an Award is paid out 
in cash rather than Shares, such cash payments will not reduce the 
number of Shares available for issuance under the Incentive Plan.  

If  we  declare  a  stock  dividend  or  engage  in  a  reorganization  or 
other  change  in  our  capital  structure,  including  a  merger,  our 
Board of Directors will have the discretion to adjust the number of 
shares:  

•  available for issuance under the Incentive Plan  

•  subject to outstanding Awards  

•  specified  as  per-person  limits  on  Awards,  as  appropriate  to 

reflect the change  

A  committee  or  committees  of  independent,  non-employee 
directors satisfying applicable laws and appointed by our Board of 
Directors  administers  the  Incentive  Plan.  To  make  grants  to 
certain  of  our  officers  and  key  employees,  the  members  of  the 
committee(s)  must  qualify  as  “non-employee  directors”  under 
Rule 16b-3  of  the  Securities  Exchange  Act  of  1934,  and  as 
“outside directors” under Section 162(m) of the Internal Revenue 
Code of 1986, as amended (the “Code”) so that we can receive a 
federal  tax  deduction  for  certain  compensation  paid  under  the 
Incentive  Plan.  Subject  to  the  terms  of  the  Incentive  Plan,  the 
administrator  has  the  sole  discretion  to  select  the  employees, 
consultants, and directors who will receive Awards, determine the 
terms and conditions of Awards, and to interpret the provisions of 
the  Incentive  Plan  and  outstanding  Awards.  Notwithstanding  the

Options  

Stock Appreciation Rights  

foregoing, without the consent of the Company’s stockholders and 
the applicable Award holder, the administrator may not modify or 
amend an option or stock appreciation right to reduce the exercise 
price  of  that  Award  after  it  has  been  granted  or  to  cancel  any 
outstanding option or stock appreciation right and replace it with a 
new option or stock appreciation right with a lower exercise price. 

the 

The administrator is able to grant nonstatutory stock options and 
Incentive  Plan.  The 
incentive  stock  options  under 
administrator  determines  the  number  of  shares  subject  to  each 
option, although the Incentive Plan provides that a participant may 
not  receive  options  for  more  than  1,000,000 shares  in  any  fiscal 
year,  except  in  connection  with  his  or  her  initial  service  as  an 
employee  with  us,  in  which  case  he  or  she  may  be  granted  an 
option to purchase up to an additional 1,000,000 shares.  

The administrator determines the exercise price of options granted 
under  the  Incentive  Plan,  provided  the  exercise  price  must  be  at 
least equal to the fair market value of our Common Stock on the 
date of grant. In addition, the exercise price of an incentive stock 
option granted to any participant who owns more than 10% of the 
total voting power of all classes of our outstanding stock must be 
at  least  110%  of  the  fair  market  value  of  our  Common  Stock on 
the grant date.  

The term of an option may not exceed ten years, except that, with 
respect to any participant who owns 10% of the voting power of 
all  classes  of  our  outstanding  capital  stock,  the  term  of  an 
incentive stock option may not exceed five years.  

After termination of service with us, a participant will be able to 
exercise  the  vested  portion  of  his  or  her  option  for  the  period  of 
time stated in the Award agreement. If no such period of time is 
stated  in  the  participant’s  Award  agreement,  the  participant  will 
generally be able to exercise his or her option for (i) three months 
following  his  or  her  termination  for  reasons  other  than  death  or 
disability, and (ii) twelve months following his or her termination 
due to death or disability. In no event may an option be exercised 
later than the expiration of its term.  

The administrator is able to grant stock appreciation rights, which 
are  the  rights  to  receive  the  appreciation  in  fair  market  value  of 
common  stock  between  the  exercise  date  and  the  date  of  grant. 
We can pay the appreciation in either cash or shares of common 
stock.  Stock  appreciation  rights  become  exercisable  at  the  times 
and  on  the  terms  established  by  the  administrator,  subject  to  the 
terms  of  the  Incentive  Plan.  The  administrator,  subject  to  the 
terms of the Incentive Plan, has complete discretion to determine 
the  terms  and  conditions  of  stock  appreciation  rights  granted 
under  the  Incentive  Plan,  provided,  however,  that  the  exercise 
price  may  not  be  less  than  100%  of  the  fair  market  value  of  a

Restricted Stock  

share on the date of grant. The term of a stock appreciation right 
may  not  exceed  ten  years.  No  participant  will  be  granted  stock 
appreciation  rights  covering  more  than  1,000,000 shares  during 
any  fiscal  year,  except  that  a  participant  may  be  granted  stock 
appreciation  rights  covering  up  to  an  additional  1,000,000 shares 
in connection with his or her initial service as  an employee with 
us.  Shares retained by the Company to pay withholding taxes in 
connection  with  the  grant  of  a  stock  appreciation  right  do  not 
become  available  for  issuance  as  future  awards  under  the 
Incentive Plan. 

After termination of service with us, a participant will be able to 
exercise  the  vested  portion  of  his  or  her  stock  appreciation  right 
for the period of time stated in the Award agreement. If no such 
period  of  time  is  stated  in  a  participant’s  Award  agreement,  a 
participant  will  generally  be  able  to  exercise  his  or  her  stock 
appreciation  right  for  (i) three  months  following  his  or  her 
termination  for  reasons  other  than  death  or  disability,  and 
(ii) twelve months following his or her termination due to death or 
disability. In no event will a stock appreciation right be exercised 
later than the expiration of its term.  

Awards of restricted stock are rights to acquire or purchase shares 
of  our  Common  Stock,  which  vest  in  accordance  with  the  terms 
and  conditions  established  by  the  administrator  in  its  sole 
discretion  provided,  however,  that,  an  Award  of  restricted  stock 
will  not  vest  more  rapidly  than  one-third  (1/3rd)  of  the  total 
number  of  shares  of  restricted  stock  each  year  from  the  date  of 
grant,  unless  the  administrator  determines  that  the  Award  of 
  on  the  achievement  of 
restricted  stock  is  to  vest  upon 
performance  criteria  and 
for  measuring  such 
performance  will  cover  at  least  twelve  (12)  months;  provided, 
further,  that  the  administrator  may  grant  Awards  of  restricted 
stock,  restricted  stock  units,  and  performance  units/shares 
covering  up  to  5%  of  the  total  number  of  shares  reserved  for 
issuance  under  the  Plan  that  do  not  satisfy  the  forgoing  vesting 
requirements. 

the  period 

The administrator, in its sole discretion,  may provide at the time 
of  or  following  the  date  of  grant  for  accelerated  vesting  for  an 
Award  of  restricted  stock  (except  that  the  number  of  shares 
subject  or  issuable  pursuant  to  Awards  of  restricted  stock, 
restricted  stock  units,  and  performance  units/shares  eligible  for 
such accelerated vesting shall not exceed 5% of the total number 
of shares reserved for issuance under the Plan) or for accelerated 
vesting upon or in connection with a change in control or upon or 
in  connection  with  a  participant’s  termination  of  service  due  to 
death, disability or retirement.   

The Award agreement generally will grant us a right to repurchase 
or  reacquire  the  shares  upon  the  termination  of  the  participant’s

Restricted Stock Units  

service with us for any reason (including death or disability). The 
administrator  will  determine  the  number  of  shares  granted 
pursuant to an Award of restricted stock, but no participant will be 
granted a right to purchase or acquire more than 200,000 shares of 
restricted  stock  during  any  fiscal  year,  except  that  a  participant 
may  be  granted  up  to  an  additional  300,000 shares  of  restricted 
stock in connection with his or her initial employment with us.  

Awards  of  restricted  stock  units  result  in  a  payment  to  a 
participant only if the vesting criteria the administrator establishes 
is satisfied, provided, however, that, an Award of restricted stock 
units will not vest more rapidly than one-third (1/3rd) of the total 
number of restricted stock units each year from the date of grant, 
unless the administrator determines that the restricted stock units 
are to vest upon  the achievement of performance criteria and the 
period for measuring such performance will cover at least twelve 
(12)  months;  provided,  further,  that  the  administrator  may  grant 
Awards of restricted stock, restricted stock units, and performance 
units/shares  covering  up  to  5%  of  the  total  number  of  shares 
reserved  for  issuance  under  the  Plan  that  do  not  satisfy  the 
forgoing  vesting  requirements.  Upon  satisfying  the  applicable 
vesting  criteria,  the  participant  will  be  entitled  to  the  payout 
specified in the Award agreement.  

Notwithstanding  the  foregoing  and  subject  to  any  restrictions 
otherwise provided herein, at any time after the grant of restricted 
stock  units,  the  administrator  may  reduce  or  waive  any  vesting 
criteria that must be met to receive a payout.  

Further,  the  administrator,  in  its  sole  discretion,  may  provide  at 
the time of or following the date of grant for accelerated vesting 
for an Award of restricted stock (except that the number of shares 
subject  or  issuable  pursuant  to  Awards  of  restricted  stock, 
restricted  stock  units,  and  performance  units/shares  eligible  for 
such accelerated vesting shall not exceed 5% of the total number 
of shares reserved for issuance under the Plan) or for accelerated 
vesting upon or in connection with a change in control or upon or 
in  connection  with  a  participant’s  termination  of  service  due  to 
death, disability or retirement.  

The administrator, in its sole discretion, may pay earned restricted 
stock  units  in  cash,  shares,  or  a  combination  thereof.  Restricted 
stock units that are fully paid in cash will not reduce the number 
of shares available for grant under the Incentive Plan. On the date 
set  forth  in  the  Award  agreement,  all  unearned  restricted  stock 
units  will  be  forfeited  to  us.  The  administrator  determines  the 
number  of  restricted  stock  units  granted  to  any  participant,  but 
during  any  fiscal  year,  no  participant  may  be  granted  more  than 
200,000 restricted stock units, except that the participant may be 
granted  up  to  an  additional  300,000  restricted  stock  units  in 
connection with his or her initial employment with us.

Performance Units and Performance 
Shares  

The  administrator  is  able  to  grant  performance  units  and 
performance shares, which are Awards that result in a payment to 
a participant only if the performance goals or other vesting criteria 
the  Awards 
the  administrator  establishes  are  achieved  or 
otherwise  vest,  provided,  however,  that,  Awards  of  performance 
units and performance shares will not vest more rapidly than one-
third  (1/3rd)  of  the  total  number  of  performance  units  and 
performance  shares  each  year  from  the  date  of  grant,  unless  the 
administrator  determines 
the  performance  units  and 
performance  shares  are  to  vest  upon  the  achievement  of 
performance  criteria  and 
for  measuring  such 
performance  will  cover  at  least  twelve  (12)  months;  provided, 
further,  that  the  administrator  may  grant  Awards  of  restricted 
stock,  restricted  stock  units,  and  performance  units/shares 
covering  up  to  5%  of  the  total  number  of  shares  reserved  for 
issuance  under  the  Plan  that  do  not  satisfy  the  forgoing  vesting 
requirements.  

the  period 

that 

The administrator, in its sole discretion,  may provide at the time 
of  or  following  the  date  of  grant  for  accelerated  vesting  for  an 
Award of performance units and performance shares (except that 
the  number  of  shares  subject  or  issuable  pursuant  to  awards  of 
restricted  stock, 
restricted  stock  units,  and  performance 
units/shares eligible for such accelerated vesting shall not exceed 
5% of the total number of shares reserved for issuance under the 
Plan)  or  for  accelerated  vesting  upon  or  in  connection  with  a 
change  in  control  or  upon  or  in  connection  with  a  participant’s 
termination of service due to death, disability or retirement.  

The administrator establishes performance or other vesting criteria 
in its discretion, which, depending on the extent to which they are 
met,  will  determine  the  number  and/or  the  value  of  performance 
units  and  performance  shares  to  be  paid  out  to  participants. 
Notwithstanding  the  foregoing,  after  the  grant  of  performance 
units  or  shares,  the  administrator,  in  its  sole  discretion,  may 
reduce  or  waive  any  performance  objectives  or  other  vesting 
provisions for such performance units or shares. During any fiscal 
year,  no  participant  will  receive  more  than  200,000  performance 
shares and no participant will receive performance units having an 
initial value greater than $2,000,000, except that a participant may 
be  granted  performance  shares  covering  up  to  an  additional 
300,000 shares  in  connection  with  his  or  her  initial  employment 
with  us.  Performance  units  will  have  an  initial  dollar  value 
established  by  the  administrator  on  or  before  the  date  of  grant. 
Performance  shares  will  have  an  initial  value  equal  to  the  fair 
market value of a share of our Common Stock on the grant date.  

Awards  of  restricted  stock,  restricted  stock  units,  performance 
shares, performance units and other incentives under the Incentive 
Plan may be made subject to the attainment of performance goals

relating  to  one  or  more  business  criteria  within  the  meaning  of 
Section 162(m) of the Code and may provide for a targeted level 
or  levels  of  achievement  including:  cash  flow;  cash  position; 
earnings before interest and taxes; earnings before interest, taxes, 
depreciation  and  amortization;  earnings  per  share;  economic 
profit;  economic  value  added;  equity  or  stockholder’s  equity;

equity;  ratio  of  operating  earnings  to  capital  spending;  sales 
growth;  return  on  net  assets;  or  total  return  to  stockholders.  The 
performance  goals  may  differ  from  participant  to  participant  and 
from  Award  to  Award  and  may  be  used  to  measure  the 
performance  of  our  business  as  a  whole  or  one  of  our  business 
units and may be measured relative to a peer group or index.  

The  Incentive  Plan  provides  for  automatic,  nondiscretionary 
awards  to  non-employee  directors.  The  automatic  grants  do  not 
limit  the  ability  of  the  administrator  to  grant  other  discretionary 
awards  to  non-employee  directors  under  the  Incentive  Plan  and 
the  administrator  has  the  discretion  to  change  the  terms  of  the 
automatic grants prospectively. 

Each  non-employee  director  will  be  automatically  granted  a 
nonstatutory  stock  option  to  purchase  40,000 shares  when  he  or 
she first becomes a member of our Board of Directors. The term 
of such options shall not exceed ten years. The option grants vest 
over  a  four-year  period,  with  one-eighth  of  shares  subject  to  the 
option vesting six months after the date of grant and the remaining 
shares  vesting  ratably  each  month  thereafter,  subject  to  the  non-
employee  director  continuing  to  serve  through  each  applicable 
vesting date.  

Each non-employee director shall automatically receive an annual 
award  of  restricted  stock  units  on  October  1  of  each  year.  The 
number  of  restricted  stock  units  subject  to  the  award  will  be 
determined in the sole discretion of our Board of Directors on or 
prior to the award becoming effective on the applicable October 1 
grant date. For a description of the current non-employee director

in  full  at  the  end  of  a  one-year  period,  subject  to  the  non-
employee  director  continuing  to  serve  through  each  applicable 
vesting date. If the non-employee discontinues service prior to the 
vesting of any restricted stock unit grant, the administrator may, in 
its discretion, permit such grant to vest pro rata for the portion of 
the year during which such director served.

Transferability of Awards  

Change of Control  

Amendment and Termination of the 

Incentive Plan  

Awards  granted  under  the  Incentive  Plan  are  generally  not 
transferable, and all rights with respect to an Award granted to a 
participant  generally  will  be  available  during  a  participant’s 
lifetime only to the participant or such participant’s estate.  

The terms of the Incentive Plan provide that all outstanding equity 
awards may vest upon a “double-trigger” termination in the event 
of  a  change  of  control,  as  described  under  the  “Executive 
Compensation —  Outstanding  Equity  Awards 
at  Fiscal 
2011 Year-End” table.  

The administrator will have the authority to amend, alter, suspend 
or  terminate  the  Incentive  Plan,  except  that  stockholder  approval 
will  be  required  for  any  amendment  to  the  Incentive  Plan  to  the 
extent required by any applicable laws. No amendment, alteration, 
suspension  or  termination  of  the  Incentive  Plan  will  impair  the 
rights  of  any  participant,  unless  mutually  agreed  otherwise 
between 
the  administrator  and  which 
agreement must be in writing and signed by the participant and us.

Employees, Consultants, and Directors 

The  number  of  Awards  that  an  employee,  director  or  consultant 
may  receive  under  the  Incentive  Plan  is  in  the  discretion  of  the 
administrator and therefore cannot be determined in advance.  

The following table sets forth (i) the aggregate number of shares 
of  common  stock  subject  to  options  granted  under  the  Incentive 
Plan during the last fiscal year, (ii) the average per share exercise 
price of such options, (iii) the aggregate number of shares issued 
pursuant to awards of restricted stock granted under the Incentive 
Plan  during  the  last  fiscal  year,  and  (iv) the  dollar  value  of  such 
shares based on the closing price per share on the grant dates.

Nonstatutory Stock Options  

Incentive Stock Options  

The  following  paragraphs  are  a  summary  of  the  general  federal 
income  tax  consequences  to  U.S.  taxpayers  and  Awards  granted 
under  the  Incentive  Plan  by  us.  Tax  consequences  for  any 
particular individual may be different. The Incentive Plan does not 
purport to be complete, and does not discuss the tax consequences 
of  a  participant’s  death  or  the  income  tax  laws  of  any  state  or 
foreign country in which the participant may reside.  

No taxable income is reportable when a nonstatutory stock option 
with  an  exercise  price  equal  to  the  fair  market  value  of  the 
underlying  stock  on  the  date  of  grant  is  granted  to  a  participant. 
Upon  exercise,  the  participant  will  recognize  ordinary  income  in 
an  amount  equal  to  the  excess  of  the  fair  market  value  (on  the 
exercise  date)  of  the  shares  purchased  over  the  exercise  price  of 
the option. Any taxable income recognized in connection with an 
option  exercise  by  an  employee  is  subject  to  tax  withholding  by 
us.  Any  additional  gain  or  loss  recognized  upon  any  later 
disposition of the shares would be capital gain or loss.  

No taxable income is reportable when an incentive stock option is 
granted  or  exercised  (except  for  purposes  of  the  alternative 
minimum  tax,  in  which  case  taxation  is  the  same  as  for 
nonstatutory stock options). If the participant exercises the option 
and then later sells or otherwise disposes of the shares more than 
two  years  after  the  grant  date  and  more  than  one  year  after  the 
exercise  date,  the  difference  between  the  sale  price  and  the 
exercise  price  will  be  taxed  as  capital  gain  or  loss.  If  the

participant  exercises  the  option  and  then  later  sells  or  otherwise 
disposes  of  the  shares  before  the  end  of  the  two-  or  one-year 
holding  periods  described  above,  he  or  she  generally  will  have 
ordinary  income  at  the  time  of  the  sale  equal  to  the  fair  market 
value of the shares on the exercise date (or the sale price, if less) 
minus the exercise price of the option.  

No  taxable  income  is  reportable  when  a  stock  appreciation  right 
with  an  exercise  price  equal  to  the  fair  market  value  of  the 
underlying  stock  on  the  date  of  grant  is  granted  to  a  participant. 
Upon  exercise,  the  participant  will  recognize  ordinary  income  in 
an  amount  equal  to  the  amount  of  cash  received  and  the  fair 
market value of any shares received. Any additional gain or loss 
recognized  upon  any  later  disposition  of  the  shares  would  be 
capital gain or loss.  

A  participant  generally  will  not  have  taxable  income  at  the  time 
an  Award  of  restricted  stock,  restricted  stock  units,  performance 
shares  or  performance  units  are  granted.  Instead,  he  or  she  will 
recognize ordinary income in the first taxable year in which his or 
her  interest  in  the  shares  underlying  the  Award  becomes  either 
(i) freely transferable or (ii) no longer subject to substantial risk of 
forfeiture. However, the recipient of a restricted stock Award may 
elect to recognize income at the time he or she receives the Award 
in  an  amount  equal  to  the  fair  market  value  of  the  shares 
underlying  the  Award  (less  any  cash  paid  for  the  shares)  on  the 
date the Award is granted.  

We  generally  will  be  entitled  to  a  tax  deduction  in  connection 
with an Award under the Incentive Plan in an amount equal to the 
ordinary  income  realized  by  a  participant  and  at  the  time  the 
participant recognizes such income (for example, the exercise of a 
nonstatutory stock option). Special rules limit the deductibility of 
certain  compensation  paid  to  our  Chief  Executive  Officer,  Chief 
Financial  Officer  and  to  each  of  our  three  highest  compensated 
officers. Under Section 162(m) of the Internal Revenue Code, no 
deduction is allowed for certain compensation with respect to any 
of these specified executives only to the extent that the amount for 
the 
taxable  year  for  such  executive  exceeds  $1,000,000.  
However,  the  deductibility  of  such  compensation  in  excess  of 
$1,000,000  may  not  be  limited  under  Section 162(m)  and  the 
applicable  treasury  regulations  if  such  compensation  qualifies  as 
performance based.  

Section 409A  of  the  Code  provides  certain  new  requirements  on 
non-qualified deferred compensation arrangements. These include 
new requirements with respect to an individual’s election to defer 
compensation  and  the  individual’s  selection  of  the  timing  and 
form  of  distribution  of  the  deferred  compensation.  Section 409A 
also  generally  provides  that  distributions  must  be  made  on  or 
following  the  occurrence  of  certain  events  (e.g.,  the  individual’s 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-19- 

 
 
 
 
 
 
 
 
 
 
separation from service, a predetermined date, or the individual’s 
death).  Section 409A  imposes  restrictions  on  an  individual’s 
ability  to  change  his  or  her  distribution  timing  or  form  after  the 
compensation  has  been  deferred.  For  certain  individuals  who  are 
officers, Section 409A requires that such individual’s distribution 
commence  no  earlier  than  six  months  after  such  officer’s 
separation from service.  

Awards  granted  under  the  Incentive  Plan  with  a  deferral  feature 
will be subject to the requirements of Section 409A. If an Award 
is subject to and fails to satisfy the requirements of Section 409A, 
the recipient of that award may recognize ordinary income on the 
amounts  deferred  under  the  Award,  to  the  extent  vested,  which 
may  be  prior

constructively  received.  Also,  if  an  Award  that  is  subject  to 
Section 409A  fails  to  comply  with  Section 409A’s  provisions, 
Section 409A  imposes  an  additional  20%  federal  income  tax  on 
compensation  recognized  as  ordinary  income,  as  well  as  interest 
on such deferred compensation. In addition, certain states such as 
California have adopted similar provisions.

PROPOSAL FOUR: 
 APPROVAL OF THE AMENDMENT TO THE 2006 EMPLOYEE STOCK PURCHASE PLAN 

The stockholders are being asked to approve an amendment to our 2006 Employee Stock Plan, as amended 
and restated on February 21, 2007 (the “Purchase Plan”) to add 1,500,000 shares to the total number of shares 
reserved  for  issuance  under  the  Purchase  Plan.  Our  Board  of  Directors  has  approved  the  increase  in  the 
number of shares reserved for issuance under the Purchase Plan, subject to approval from stockholders at the 
Annual Meeting. If stockholders do not approve the amendment to the Purchase Plan, no shares will be added 
to the total number of shares reserved for issuance under the Purchase Plan. 

Our  named  executive  officers  have  an  interest  in  this  proposal  as  they  are  eligible  to  receive  options  to 

purchase shares under the Purchase Plan. 

Our Board of Directors believes that approval of the amendment is essential to our continued success, as 
the additional shares will enable us to continue to use the Purchase Plan to achieve employee performance, 
recruiting, retention and incentive goals. In particular, our Board of Directors believes that our employees are 
our  most  valuable  assets  and  that  the  awards  permitted  under  the  Purchase  Plan  are  vital  to  our  ability  to 
attract  and  retain  outstanding  and  highly  skilled  individuals  in  the  extremely  competitive  labor  markets  in 
which we compete. Such awards also are crucial to our ability to motivate employees to achieve our goals.

General 

Administration 

Eligibility 

Approval  of  the  Amendment  to  the  Purchase  Plan  requires  the 
affirmative vote of a majority of the shares of our Common Stock 
that  are  present  in  person  or  proxy  and  entitled  to  vote  at  the 
Annual Meeting.  

Our Board of Directors recommends that you vote “FOR” the 
Amendment  to  the  2006  Employee  Stock  Purchase  Plan  and 
the  increase  to  the  number  of  shares  reserved  for  issuance 
thereunder.  

The  following  is  a  summary  of  the  principal  features  of  the 
Purchase  Plan  and  its  operation.  The  summary  is  qualified  in  its 
entirety  by  reference  to  the  Purchase  Plan,  as  amended  giving 
effect to this Proposal Four, set forth in Appendix B.  

The  Purchase  Plan  was  adopted  by  the  Board  of  Directors  in 
March  2006,  and  approved  by  our  stockholders  at  the  2006 
Annual Meeting. The purpose of the Purchase Plan is to provide 
employees with an opportunity to purchase shares of our Common 
Stock through payroll deductions. 

The Board of Directors or a committee appointed by the Board of 
the  Directors  administers  the  Purchase  Plan.  All  questions  of 
interpretation  or  application  of  the  Purchase  Plan  are  determined 
by  the  administrator  and  its  decisions  are  final,  conclusive  and 
binding upon all participants. 

Each  of  our  employees  or  the  employees  of  our  designated 
subsidiaries  who  is  a  common  law  employee  and  whose 
customary  employment  with  us  or  one  of  our  designated 
subsidiaries is at least twenty hours per week and more than five

months in a calendar year is eligible to participate in the Purchase 
Plan  subject  to  the  laws  in  which  our  designated  subsidiaries 
operate; except that no employee shall be granted an option under 
the  Purchase  Plan  (i)  to  the  extent  that,  immediately  after  the 
grant,  such  employee  would  own  5%  or  more  of  the  total 
combined  voting  power  of  all  classes  of  our  capital  stock  or  the 
capital  stock  of  one  of  the  designated  subsidiaries,  or  (ii)  to  the 
extent  that  his  or  her  rights  to  purchase  stock  under  all  of  our 
employee  stock  purchase  plans  accrues  at  a  rate  which  exceeds 
$25,000 worth of stock (determined at the fair market value of the 
shares at the time such option is granted) for each calendar year. 

Each  offering  period  under  the  Purchase  Plan  will  expire  on  the 
earliest to occur of (i) the completion of the purchase of shares on 
the last exercise date occurring within twenty-four months of the 
offering date of such option, (ii) such shorter option period as may 
be determined by the administrator, or (iii) the date on which an 
eligible  employee  ceases  to  be  a  participant  under  the  Purchase 
Plan.  Each  offering  period  will  generally  consist  of  a  number  of 
purchase  periods  after  which  shares  will  be  purchased.  Until  the 
administrator  determines  otherwise,  a  purchase  period  will  be 
approximately six months and run from May 1 to November 1 and 
November  1  to  May  1.  To  participate  in  the  Purchase  Plan,  an 
eligible  employee  must  authorize  payroll  deductions  pursuant  to 
the Purchase Plan. Such payroll  deductions may not be less than 
1%  and  may  not  exceed  15%  of  a  participant’s  compensation 
during  the  offering  period.  Once  an  employee  becomes  a 
participant in the Purchase Plan, the employee automatically will 
participate  in  each  successive  offering  period  until  the  employee 
withdraws from the Purchase Plan or the employee’s employment 
with us or the designated subsidiaries terminates. At the beginning 
of each offering period, each participant automatically is granted 
an  option  to  purchase  shares  of  our  Common  Stock.  The  option 
expires  at  the  end  of  the  offering  period  or  upon  termination  of 
employment,  whichever  is  earlier,  but  is  exercised  at  the  end  of 
each  purchase  period  to  the  extent  of  the  payroll  deductions 
accumulated during such purchase period. 

Shares  of  our  Common  Stock  may  be  purchased  under  the 
Purchase Plan at a purchase price not less than 85% of the lesser 
of the fair market value of the common stock on (i) the first day of 
the offering period, or (ii) the last day of the purchase period. The 
fair market value of our Common Stock on any relevant date will 
be  the  closing  price  per  share  as  reported  on  the  Nasdaq  Stock 
Market,  or  the  mean  of  the  closing  bid  and  asked  prices,  if  no 
sales  were  reported,  as  quoted  on  such  exchange  or  reported  in 
The Wall Street Journal. 

Payment  of  Purchase  Price;  Payroll 
Deductions 

The  purchase  price  of  the  shares  is  accumulated  by  payroll 
deductions  throughout  each  purchase  period.  The  number  of 
shares  of  our  Common  Stock  that  a  participant  may  purchase  in

each purchase period during an offering period will be determined 
by dividing the total amount of payroll deductions withheld from 
the participant’s compensation during that purchase period by the 
purchase  price;  provided,  however,  that  a  participant  may  not 
purchase more than 5,000 shares each purchase period. During the 
offering  period,  a  participant  may  discontinue  his  or  her 
participation  in  the  Purchase  Plan,  and  may  decrease  or  increase 
the  rate  of  payroll  deductions  in  an  offering  period  within  limits 
set  by  the  administrator;  provided,  however,  that  unless  the 
administrator determines otherwise, a participant may reduce, but 
not increase his or her contributions during a purchase period for 
that purchase period. 

All  payroll  deductions  made  for  a  participant  are  credited  to  the 
participant’s  account  under  the  Purchase  Plan,  are  withheld  in 
whole percentages only and are included with our general funds. 
Funds  received  by  us  pursuant  to  exercises  under  the  Purchase 
Plan  are  also  used  for  general  corporate  purposes.  A  participant 
may not make any additional payments into his or her account. 

Generally, a participant may withdraw from an offering period at 
any  time  by  written  or  electronic  notice  without  affecting  his  or 
her  eligibility  to  participate  in  future  offering  periods.  However, 
once  a  participant  withdraws  from  a  particular  offering  period, 
that  participant  may  not  participate  again  in  the  same  offering 
period.  To  participate  in  a  subsequent  offering  period,  the 
participant must deliver to us a new subscription agreement. 

Upon  termination  of  a  participant’s  employment  for  any  reason, 
including  disability  or  death,  he  or  she  will  be  deemed  to  have 
elected  to  withdraw  from  the  plan  and  the  payroll  deductions 
credited  to  the  participant’s  account  (to  the  extent  not  used  to 
make a purchase of our Common Stock) will be returned to him or 
her  or,  in  the  case  of  death,  to  the  person  or  persons  entitled 
thereto  as  provided  in  the  Purchase  Plan,  and  such  participant’s 
option will automatically be terminated. 

Subject to any required action by our stockholders, the number of 
shares reserved under the Purchase Plan, the maximum number of 
shares that may be purchased during any purchase period, as well 
as  the  price  per  share  of  common  stock  covered  by  each  option 
under the Purchase Plan which has not yet been exercised shall be 
proportionately  adjusted  for  any  increase  or  decrease  in  the 
number  of  issued  shares  of  common  stock  resulting  from  any 
dividend or other distribution, recapitalization, stock split, reverse 
stock  split,  reorganization,  merger,  consolidation,  split-up,  spin-
off, combination, repurchase or exchange.

Individuals and Groups 

In  the  event  of  our  proposed  dissolution  or  liquidation,  the 
administrator  shall  shorten  any  purchase  periods  and  offering 
periods  then  in  progress  by  setting  a  new  exercise  date  and  any 
offering  periods  shall  end  on  the  new  exercise  date.  The  new 
exercise date shall be prior to the dissolution or liquidation. If the 
administrator shortens any purchase periods and offering periods 
then in progress, the administrator shall notify each participant in 
writing, at least ten business days prior to the new exercise date, 
that the exercise date has been changed to the new exercise date 
and  that  the  option  will  be  exercised  automatically  on  the  new 
exercise  date,  unless  the  participant  has  already  withdrawn  from 
the offering period. 

In the event of any “change of control,” as defined in the Purchase 
Plan, each option under the Purchase Plan shall be assumed or an 
equivalent  option  shall  be  substituted  by  such  successor 
corporation  or  a  parent  or  subsidiary  of  such  successor 
corporation.  In  the  event  the  successor  corporation  refuses  to 
assume  or  substitute  for  the  options,  the  administrator  shall 
shorten any purchase periods and offering periods then in progress 
by setting a new exercise date and any offering periods shall end 
on the new exercise date. The new exercise date shall be prior to 
the merger or change of control. If the administrator shortens any 
purchase  periods  and  offering  periods  then  in  progress,  the 
administrator  shall  notify  each  participant  in  writing,  at  least  ten 
business days prior to the new exercise date, that the exercise date 
has been changed to the new exercise date and that the option will 
be  exercised  automatically  on  the  new  exercise  date,  unless  the 
participant has already withdrawn from the offering period. 

Our  administrator  may  at  any  time  terminate  or  amend  the 
Purchase  Plan  including  the  term  of  any  offering  period  then 
outstanding.  Generally,  no  such  termination  can  adversely  affect 
options previously granted. 

Given that the number of shares that may be purchased under the 
Purchase  Plan  is  determined,  in  part,  based  on  the  Common 
Stock’s  market  value  at  the  beginning  and  end  of  each  Offering 
Period  (or  upon  a  purchase  date  within  an  Offering  Period)  and 
given  that  participation  in  the  Purchase  Plan  is  voluntary  on  the 
part  of  employees,  the  actual  number  of  shares  that  may  be 
purchased by any individual is not determinable. 

For  illustrative  purposes,  the  following  table  sets  forth  (a)  the 
number  of  shares  of  Common  Stock  that  were  purchased  under 
the  Purchase  Plan  during  2011  by  our  named  executive  officers, 
our  executive  officers  as  a  group,  and  by  all  employees,  and  (b) 
the weighted average per share purchase price paid for such shares 
by each such group.

Federal Tax Aspects  

The  following  summary  of  the  effect  of  federal  income  taxation
upon  the  participant  and  us  with  respect  to  the  shares  purchased
under the Purchase Plan does not purport to be complete, and does
not  discuss  the  tax  consequences  of  a  participant’s  death  or  the 
income  tax  laws  of  any  state  or  foreign  country  in  which  the
participant may reside. 

The Purchase Plan, and the right of participants to make purchases
thereunder, is intended to qualify under the provisions of Sections
421 and 423 of the Code. Under these provisions, no income will 
be  taxable  to  a  participant  until  the  shares  purchased  under  the
Purchase  Plan  are  sold  or  otherwise  disposed  of.  Upon  sale  or
other  disposition  of  the  shares,  the  participant  will  generally  be
subject to tax in an amount that depends upon the holding period. 
If  the  shares  are  sold  or  otherwise  disposed  of  more  than  two
years from the first day of the applicable offering period and one
year  from  the  applicable  date  of  purchase,  the  participant  will
recognize ordinary income measured as the lesser of (i) the excess 
of  the  fair  market  value  of  the  shares  at  the  time  of  such  sale  or
disposition  over  the  purchase  price,  or  (ii)  an  amount  equal  to
15% of the fair market value of the shares as of the first day of the
applicable offering period. Any additional gain will be treated as 
long-term capital gain. If the shares are sold or otherwise disposed
of  before  the  expiration  of  these  holding  periods,  the  participant
will recognize ordinary income generally measured as the excess
of  the  fair  market  value  of  the  shares  on  the  date  the  shares  are
purchased over the purchase price. Any additional gain or loss on
such  sale  or  disposition  will  be  long-term  or  short-term  capital 
gain  or  loss,  depending  on  how  long  the  shares  have  been  held
from  the  date  of  purchase.  We  generally  are  not  entitled  to  a
deduction for amounts taxed as ordinary income or capital gain to
a  participant  except  to  the  extent  of  ordinary  income  recognized
by  participants  upon  a  sale  or  disposition  of  shares  prior  to  the

expiration of the holding periods described above. 

The foregoing is only a summary of the effect of federal income
taxation  upon  participants  and  us  with  respect  to  the  grant  and
exercise of awards under the Purchase Plan. It does not purport to
be  complete,  and  does  not  discuss  the  tax  consequences  of  a
participant’s death or the provisions of the income tax laws of any
municipality, state or foreign country in which the participant may
reside.

PROPOSAL FIVE: 

APPROVAL OF THE OPTION EXCHANGE PROGRAM 

The  stockholders  are  being  asked  to  approve  a  one-time  stock  option  exchange  program  for  eligible 
employee stock option holders (the “Exchange Program”).   The proposed Exchange Program would enable 
our eligible stock option holders to surrender certain “underwater” stock options that have an exercise price 
above $14.50 per share of our common stock for cancellation in exchange for new options to be granted under 
our Incentive Plan to purchase a reduced number of shares based on a specified exchange ratio.  

We  historically  have  granted  stock  options  to  our  employees  to  encourage  them  to  act  as  owners  of  the 
Company,  which  helps  align  their  interests  with  those  of  our  stockholders  and  reward  performance  that 
enhances stockholder value. 

2011 was a mixed year for Rambus.  While our recurring revenues and pace of signing licensees improved 
during the year, the adverse decisions by the Court of Appeals for the Federal Circuit in May 2011 and in the 
San  Francisco  Superior  Court  of  the  State  of  California  in  November  2011  caused  our  share  price  to  drop 
significantly.  As a result, approximately 97% of stock options are underwater (meaning the exercise price of 
each of those stock options is greater than the per share fair market value of the Company’s common stock) as 
of March 1, 2012.  This means that the majority of these stock options are no longer effective incentives to 
motivate and retain employees.  These underwater options are perceived as having little or no value by our 
employees. In addition, although these stock options are not likely to be exercised as long as our stock price is 
lower  than  the  applicable  exercise  price,  we  will  continue  to  record  stock-based  compensation  expense  for 
these unvested options against our earnings. Further, they will remain on our books with the potential to dilute 
stockholders’ interests for up to the full term of the options, while delivering little or no retention or incentive 
value, unless they are surrendered or cancelled. 

On  February  23,  2012,  our  Board  of  Directors  authorized,  subject  to  stockholder  approval,  the  proposed 
Exchange Program that will permit our eligible employees (other than our named executive officers, all senior 
vice  presidents  and  members  of  our  Board  of  Directors)  to  exchange  certain  outstanding  stock  options  (the 
stock options eligible for the Exchange Program are referred to here as “Eligible Options”) that were granted 
with an exercise price greater than or equal to $14.50 for new options to purchase fewer shares subject to a 
specified exchange ratio.  Our intent in using this threshold is to ensure that only outstanding stock options 
that are substantially underwater are eligible for the Exchange Program.  

The  Exchange  Program  will  take  place  if  and  only  if  the  Exchange  Program  is  approved  by  our 
stockholders.    If  our  stockholders  do  not  approve  the  Exchange  Program,  Eligible  Options  would 
remain  outstanding  and  in  effect  in  accordance  with  their  existing  terms.    We  would  continue  to 
recognize compensation expense for these eligible options even though the stock options may have little 
or no retention or incentive value for employees. 

If approved by stockholders, the Exchange Program will begin within 12 months of the date stockholders 
approve the program. Within this timeframe, the actual start date will be determined at the discretion of our 
Board of Directors.   Eligible employees then will be offered the opportunity to participate in the Exchange 
Program under an offer statement to be filed with the SEC and distributed to all eligible employees. Eligible 
employees  would  be  given  at  least  twenty  business  days  to  decide  whether  to  accept  the  offer  of  the  new 
options in exchange for the surrender of their Eligible Options. The surrendered Eligible Options would be 
cancelled on the day that the Exchange Program closes and the shares subject to surrendered Eligible Options 
will not be available for reissuance under the Incentive Plan.  The new options would be granted on the date 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-27- 

 
 
 
 
 
 
 
 
of cancellation of the old Eligible Options and such new options would have an exercise price equal to the fair 
market value of our Common Stock on the date of the new grant. 

Key Features of the Option Exchange Program: 

  Our NEOs, senior executives, and Board of Directors are not eligible to participate. 

 

In aggregate, the fair value of the exchanged options will be approximately equal to the fair value of 
the new options (i.e., “value for value”), resulting in fewer options outstanding. 

  Only options with a strike price higher than $14.50 will be eligible for exchange. 

  New options will vest over three years, encouraging retention. 

  Options tendered in the exchange will be canceled and will not be reissued. 

If  approved,  the  Exchange  Program  will  begin  within  12  months  of  the  date  stockholders  approve  the 
program. 

Voting Required; Recommendation of 

the Board of Directors 

Reasons for the Exchange Program 

The  affirmative  vote  of  a  majority  of  the  outstanding  shares  of 
common  stock  present  in  person  or  represented  by  proxy  and 
entitled to vote at the Annual Meeting is required to approve the 
Exchange Program. 

Our Board of Directors recommends that you vote “FOR” the 
approval of the Exchange Program for our employees. 

Our  Board  of  Directors  believes  the  Exchange  Program  is  an 
important  component  in  our  strategy  to  align  employee  and 
stockholder  interests  through  our  equity  compensation  practices 
because it will permit us to: 

provide  renewed  incentives  for  the  employees  who 
participate in the Exchange Program by issuing them 
new stock options that will vest over a period of time 
following the exchange date if they remain employed 
with  us. 
  Providing  renewed  incentives  to  our 
employees  is  the  primary  purpose  of  the  Exchange 
Program  and  we  believe  the  Exchange  Program  will 
enable us to enhance long-term stockholder value by 
aligning  the  interests  of  our  employees  more  fully 
with the interests of our stockholders; 

or 

equity 

awards, 

meaningfully reduce our total number of shares subject to 
“overhang,” 
outstanding 
represented  by  outstanding  stock  options  that  have 
high  exercise  prices  and  may  no  longer  incentivize 
their  holders  to  remain  as  our  employees.    Keeping 
these  stock  options  outstanding  does  not  serve  the 
interests of our stockholders and does not provide the 
intended  by  our  equity  compensation 
benefits

the  surrendered  Eligible 
program.  By  replacing 
Options  with  a  lesser  number  of  new  options,  our 
overhang  will  be  decreased.  The  overhang 
represented  by  the  sstock  options  issued  pursuant  to 
the  Exchange  Program  will  reflect  an  appropriate 
balance  between

our  overhang  and  the  dilution  of  our  stockholders’

in 

recapture value from compensation costs that we already 
are  incurring  with  respect  to  outstanding  stock 
options.  These stock options were granted at the then 
fair  market  value  of  our  common  stock.    Under 
applicable accounting rules, we will have to recognize 
approximately  $189.0  million 
stock-based 
compensation  expense  related  to  these  stock  options, 
of which $153.2 million has already been expensed as 
of  December  31,  2011  and  $35.8  million  will 
continue  to  be  obligated  to  expense,  even  if  these 
the 
stock  options  are  never  exercised  because 
majority  remain  underwater.    As  of  March  1,  2012, 
the  fair  value  associated  with  outstanding  Eligible 
Options  was  approximately  $100.0  million.    We 
believe  it  is  not  an  efficient  use  of  our  resources  to 
recognize  compensation  expense  on  equity  awards 
that  do  not  provide  value  to  our  employees.    By 
replacing stock options that have little or no retention 
or  incentive  value  with  equity  awards  that  will 
provide both retention and incentive value, we will be 
making efficient use of our resources. 

Generally,  stock  options  will  be  eligible  for  exchange  in  the 
Exchange Program if: 

the  stock  option’s  exercise  price  exceeds  $14.50 
(measured  as  of  the  start  date  of  the  Exchange 
Program). 

Our intent in using this eligibility threshold is to ensure that only 
outstanding  stock  options  that  are  appropriately  underwater  are 
eligible for the Exchange Program. 

As  of  March  1,  2012,  stock  options  to  purchase  approximately 
16.4 million shares of our common stock were outstanding under 
the Plan.  For example, if we were to start the Exchange Program 
on March 1, 2012, our common stock closed at $7.06 on March 1, 
2012  and  all  stock  options  with  an  exercise  price  of  $14.50  or 
above would be eligible for the Exchange Program.  On March 1, 
2012,  the  number  of  shares  underlying  eligible  options  with  an 
exercise price of $14.50 or higher was 7.4 million shares. 

In considering how best to continue to motivate, retain and reward

our  employees  who  have  stock  options  that  are  underwater,  we 
evaluated several alternatives, including the following: 

Increase  Cash  Compensation.    To  replace  the  intended 
benefits  of  equity  incentives,  we  would  need  to 
substantially  increase  long  term  retention-based  cash 
compensation.    These  increases  would  substantially 
increase  our  compensation  expense  and  reduce  our 
cash  position  and  cash  flow  from  operations.    In 
addition,  these  increases  would  not  reduce  our 
overhang. 

Grant  Additional  Equity  Awards.    We  also  considered 
granting  employees  additional  equity  awards  at 
current  market  prices.    However,  these  additional 
grants  would  substantially  increase  our  equity  award 
to  our 
overhang  and 
stockholders  and  would  increase  our  compensation 
expense accordingly. 

the  potential  dilution 

The Exchange Program will be open to any stock option holder 
who:

holds Eligible Options;  

is not a named executive officer, senior vice president, or 

member of our Board of Directors at the start of the 
Exchange Program; and 

at the start of the Exchange Program:

o 

is an employee in our U.S. locations;  or  

is employed by or provides services to us or our 
subsidiaries, but only to the extent such stock 
option holders’ participation is permitted by local 
laws. 

We may, however, exclude otherwise eligible stock option holders 
in  certain  non-U.S.  jurisdictions  if  local  tax  or  securities  laws  or 
other  considerations  would  make  their  participation  illegal, 
infeasible  or  impractical.  Any  eligible  employee  who  elects  to 
participate  in  the  Exchange  Program  but  whose  employment 
terminates for any reason prior to the grant of the new options will 
retain  his  or  her  Eligible  Options  subject  to  their  existing  terms 
and  will  not  receive  a  new  stock  option  under  the  Exchange 
Program. 

The Exchange Program will not be a one-for-one exchange.  We 
intend to set the exchange ratios for our eligible employees so that 
the exchange will approximate a value-for-value exchange and so 
that any additional stock-based compensation charge we will incur

Eligible employees who participate in the Exchange Program, will 
receive a receive a new stock option for a lesser number of shares 
equal  to  (a)  the  number  of  shares  underlying  the  stock  option 
exchanged  multiplied  by  (b)  an  exchange  ratio  set  at  a  ratio  to 
approximate  a  value-for-value  exchange.    The  exact  exchange 
ratio will be set by our Board of Directors prior to the start date of 
the Exchange Program. 

The  exchange  ratios  of  surrendered  Eligible  Options  to  newly 
issued stock options for eligible employees will be established by 
grouping  together  Eligible  Options  with  similar  grant  dates  and 
assigning  an  appropriate  exchange  ratio  to  each  grouping.    The 
exchange  ratios  will  be  determined  so  that  the  total  fair  value  of 
all  newly  issued  options  within  each  group  will  be  equal  to  or 
slightly less than the total fair value of current option holdings. 

We will compute the exchange ratios on an accounting value-for-
value  basis  pursuant  to  Financial  Accounting  Standards  Board 
Accounting  Standards  Codification  Topic 
718,  Stock 
Compensation  (“ASC  718”)  using  the  Black-Scholes  valuation 
model.    The  calculation  of  fair  value  using  the  Black-Scholes 
model  takes  into  account  several  variables,  such  as  the  volatility 
of our stock and the expected term of an award.  As a result, the 
exchange ratios do not necessarily increase as the exercise price of 
the  stock  option  increases.  Setting  the  exchange  ratios  in  this 
manner is intended to result in the issuance of new stock options 
that have a fair value approximately equal to the fair value of the 
surrendered eligible stock options that they replace. This approach 
will  minimize  any  additional  compensation  cost  that  we  must 
recognize  on 
immaterial 
compensation  expense  that  might  result  from  fluctuations  in  our 
stock price after the exchange ratios have been set but before the 
exchange is made. 

the  stock  options,  other 

than 

Although the exchange ratios cannot be determined now, we can 
provide an example if we make certain assumptions regarding the 
start date of the offer, the fair value of the eligible stock options, 
and the fair market value of our Common Stock. For example, if 
we  began  the  Exchange  Program  March  1,  2012,  which  would 
allow  us  to  include  in  the  Exchange  Program  a  substantial 
percentage  of  our  outstanding  underwater  stock  options  with  an 
exercise price above $14.50 per share. 

If, at the time we set the exchange ratios, the fair market value of 
our Common Stock was $8.00 per share, then based on the above 
method of determining the exchange ratio, the following exchange 
ratios would apply:

The  total  number  of  new  stock  options  a  participating  employee 
will receive with respect to a surrendered Eligible Option will be 
determined  by  converting  the  number  of  shares  underlying  the 
surrendered Eligible Option according to the applicable exchange 
ratio and rounding down to the nearest whole share. The exchange 
ratios will be applied in groupings of grants based on price. 

For  purposes  of  example  only,  if  a  participating  employee 
exchanged  an  Eligible  Option  for  1,000  shares  with  an  exercise 
price  of  $14.75  per  share  granted  on  June  7,  2005  and  the 
exchange  ratio  was  one  new  stock  option  for  every  3.75  shares 
covered  by  the  surrendered  Eligible  Option,  he  or  she  would 
receive  266  new  stock  options  in  exchange  for  the  surrendered 
stock option (1,000 divided by 3.75). If the participating employee 
also  exchanged  another  Eligible  Option  for  2,000  shares  with  an 
exercise  price  of  $20.16  per  share  granted  on  December  1,  2010 
and  the  exchange  ratio  was  one  new  stock  option  for  every  2 
shares  covered  by  the  surrendered  Eligible  Option,  he  or  she 
would  receive  1,000  new  stock  options  in  exchange  for  the 
surrendered eligible award (2,000 divided by 2). 

Continuing  this  example,  if  we  assume  that  all  currently  eligible 
stock  options  remain  outstanding  and  the  stock  option  holders 
remain  eligible  to  participate,  the  following  table  summarizes

*For  purposes  of  this  example,  the  remaining  weighted  average  life  of 
the eligible options is based on a June 1, 2012 start date. 

Eligible  employees  will  not  be  required  to  participate  in  the 
Exchange  Program.    Participation  in  the  Exchange  Program  is 
strictly voluntary. 

Eligible  employees  will  have  an  election  period  of  at  least  20 
business days from the start of the Exchange Program in which to 
determine whether they wish to participate. 

Because  the  decision  whether  to  participate  in  the  Exchange 
Program is completely voluntary, we are not able to predict which 
or  how  many  employees  will  elect  to  participate,  how  many 
Eligible  Options  will  be  surrendered  for  exchange,  and  therefore 
how many new stock options may be issued.

Options 

Term and Vesting of New Options 

Terms of New Options 

Terms of the Exchange Program 

Program. 

Eligible  employees  may  decide  to  participate  in  the  Exchange 
Program  on  a  grant-by-grant  basis.    This  means  that  eligible 
employees may elect to tender any or all of their Eligible Options.  
However,  if  an  eligible  employee  elects  to  tender  any  shares 
subject  to  a  particular  Eligible  Option in  the  Exchange  Program, 
then  the  eligible  employee  must  tender  all  shares  subject  to  that 
particular Eligible Option. 

None  of  the  new  stock  options  issued  in  the  Exchange  Program 
will be vested on the date of grant, but will become vested on the 
basis of the participating employee’s continued services with us or 
any or our subsidiaries.  All new stock options will be subject to a 
three  year  vesting  schedule.    The  rate  at  which  the  new  stock 
options will vest be as follows: 

1/3  of  the  new  stock  option  will  vest  on  the  one  year 

anniversary of the exchange date; and 

2/3  of  the  new  stock  option  will  vest  over  the  next  two 
years  in  equal  monthly  installments  thereafter  on  the 
monthly anniversary of the exchange date. 

Each new stock option will have a new term equal to the longer of 
five  years  or  the  original  term  of  the  Eligible  Option  it  replaces, 
subject  to  earlier  termination  in  the  event  of  the  employee’s 
termination of employment with us or one of our subsidiaries. 

Each  new  stock  option  issued  in  the  Exchange  Program  will 
represent  a  right  to  purchase  shares  of  our  Common  Stock  on  a 
specified  future  date  at  the  fair  market  value  of  our  Common 
Stock on the date of issuance.  All new options granted pursuant 
to  the  Exchange  Program  will  retain  the  status  as  the  Eligible 
Option it replaces to the extent permissible under the law (e.g., if 
an  Eligible  Option  was  intended  to  be  an  incentive  stock  option 
within the meaning of Section 422 of the Internal Revenue Code 
of  1986,  as  amended,  then  the  new  option  will  be  an  incentive 
stock option to the extent permissible under the law). Except for 
the different exercise price, the vesting schedule described above, 
and the new term described above, all other terms and conditions 
of the new stock options issued in the Exchange Program will be 
substantially  the  same  as  those  that  apply  to  Eligible  Options 
granted  previously,  except  that  prior  grants  made  from  equity 
plans other the Incentive Plan, if any, will now be governed by the 
terms and conditions of the Incentive Plan. 

While  the  terms  of  the  Exchange  Program  are  expected  to  be 
materially similar to the terms described in this proposal, we may 
find  it  necessary  or  appropriate  to  change  the  terms  of  the 
exchange  program  to  take  into  account our  administrative  needs, 
law  requirements,  accounting  rules,  company  policy 
local

decisions  that  make  it  appropriate  to  change  the  exchange 
program  and  the  like.    For  instance,  although  we  will  not  allow 
stock options below an exercise price which is at least $14.50, we 
may decide to exclude stock options granted below a higher price-
point.    As  another  example,  we  may  alter  the  method  of 
determining  exchange  ratios  if  we  decide  that  there  is  a  more 
efficient  and  appropriate  way  to  set  the  ratios  while  still 
continuing to limit incremental compensation expense. 

It is also possible that certain terms of the Exchange Program may 
need to be modified in countries outside the United States in order 
to  comply  with  local  requirements,  or  for  tax,  accounting  or 
administrative reasons and/or that the exchange program may not 
be  implemented  in  certain  jurisdictions  outside  the  United  States 
if local law, expense, complexity, administrative burden or similar 
considerations  would  make  it  illegal,  infeasible  or  impractical  to 
do  so.  Additionally,  we  may  decide  not  to  implement  the 
Exchange Program  even if stockholder approval of the exchange 
program  is  obtained  or  may  amend  or  terminate  the  exchange 
program  once  it  is  in  progress  if  our  stock  price  increases 
significantly  or  other  factors  that  may  render  the  Exchange 
Program  detrimental  to  the  Company  and  the  long  term  interests 
of  the  stockholders.    The  final  terms  of  the  Exchange  Program 
will be described in an offer to exchange that will be filed with the 
SEC.  Although we do not anticipate that the staff of the SEC will 
require  us  to  materially  modify  the  terms  of  the  exchange 
program, it is possible that we may need to alter the terms of the 
Exchange Program to comply with comments from the staff. 

The  following  is  a  summary  of  the  anticipated  material  United 
States  federal  income  tax  consequences  of  participating  in  the 
Exchange  Program.  A  more  detailed  summary  of  the  applicable 
tax considerations to participants will be provided in the offer to 
exchange.  The  tax  consequences  of  the  program  are  not  entirely 
certain,  however,  and  the  Internal  Revenue  Service  is  not 
precluded  from  adopting  a  contrary  position,  and  the  law  and 
regulations  themselves  are  subject  to  change.  We  believe  the 
exchange  of  Eligible  Options  for  new  options  pursuant  to  the 
program should be treated as a non-taxable exchange and neither 
we  nor  any  of  our  eligible  employees  should  recognize  any 
income  for  U.S.  federal  income  tax  purposes  upon  the  surrender 
of  eligible  options  and  the  grant  of  new  options.  If  the  option 
Exchange Program is open for 30 days or more, Eligible Options 
that were intended to be incentive stock options will be considered 
“modified,” which will result in a deemed re-grant of the Eligible 
Option,  whether  or  not  they  were  exchanged.  This  would  mean 
that  for  purposes  of  the  incentive  stock  option  rules  the  holding 
period  measured  from  the  date  of  grant  would  restart  and  the 
option holder would not receive  any credit for the time from the 
original grant date of the eligible option.

specific budget.  The independent registered public accounting firm and 
management are required to periodically report to the Audit Committee 
regarding the extent of services provided by the independent registered 
public accounting firm in accordance with this pre-approval, and the fees 
for the services performed to date.  The Audit Committee may also pre-
approve particular services on a case-by-case basis.

The Audit Committee has determined that the accounting advice and tax

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT 

Under the proxy rules of the SEC, a person who directly or indirectly has or shares voting power or 

investment power with respect to a security is considered a beneficial owner of the security.  Voting power is 
the power to vote or direct the voting of shares, and investment power is the power to dispose of or direct the 
disposition of shares.  Shares as to which voting power or investment power may be acquired within 60 days 
are also considered as beneficially owned under the proxy rules. 

The following table sets forth certain information as of March 1, 2012, regarding beneficial 
ownership of our Common Stock by: (i) each person who is known to us to own beneficially more than five 
percent of our Common Stock; (ii) each of our current directors; (iii) each of the named executive officers in 
the Summary Compensation Table of this annual report; and (iv) the total for our current directors and current 
executive officers as a group.  The information on beneficial ownership in the table and the footnotes is based 
upon our records and the most recent Schedule 13D or 13G filed by each such person or entity and 
information supplied to us by such person or entity.  Unless otherwise indicated, each person has sole voting 
power and sole investment power with respect to all shares beneficially owned, subject to community 
property laws where applicable.  Shares subject to options which are exercisable within 60 days of March 1, 
2012 are deemed to be outstanding and to be beneficially owned by the person holding such options for the 
purpose of computing the percentage ownership of such person, but are not deemed to be outstanding and to 
be beneficially owned for the purpose of computing the percentage ownership of any other person.

EXECUTIVE COMPENSATION 

COMPENSATION DISCUSSION & ANALYSIS 

This Compensation Discussion and Analysis describes our compensation policies, programs, and pay 

actions for our Named Executive Officers (“NEOs”) as identified in the Summary Compensation Table. 

We have organized this report as follows: 

1.  Executive summary that includes discussion our business performance and the key factors in 

our 2011 NEO compensation, which are described in more detail in this report 

2.  Assessment of pay-for-performance 

3.  NEO compensation process 

4.  Tools used in the compensation-setting process 

5.  Components of NEO compensation 

6.  Other policies and elements of NEO compensation 

EXECUTIVE SUMMARY 

2011 Business Performance 

2011 was a mixed year for Rambus.  The continued execution of our diversification strategy and 

strong results in ongoing business initiatives were offset by adverse decisions by the Court of Appeals for the 
Federal Circuit in May 2011 and in the San Francisco Superior Court of the State of California in November 
2011.  While our recurring revenues and pace of signing licensees improved during the year, the adverse 
verdict in the price-fixing case caused our share price to drop significantly.  Going forward, our intent is to 
continue to sign meaningful licenses and to increase the number of and pace at which we sign them.  We 
expect to see results from our diversification strategy, with new licensees in newer areas, and exhibit 
continued positive momentum in fulfilling our mission of licensing our world-class patent portfolio and 
providing technology solutions that enrich the end-user experience of electronic systems. 

Our 2011 business highlights included: 

$312.4 million in annual revenue. 

Semiconductors: We signed or re-signed a number of key patent license agreements during the year, 

including Toshiba, Panasonic, Freescale and Broadcom. 

Lighting and Display: GE Lighting demonstrated prototypes of energy-efficient fixtures based on our 

lighting innovations. 

2011 10-K & Proxy Combo bannerless FINAL.docx

Cryptography: We acquired Cryptography Research Inc., (CRI) in June 2011.  Our CRI team signed 
license agreements with a major smartphone and tablet manufacturer, Verimatrix, CPU Tech and 
Mikron, and partnership agreements with INVIA and Keirex. 

We grew our patent portfolio by more than 20%.  At year-end, we had 1,386 patents and 1,059 

pending applications. 

2011 NEO Compensation Highlights 

We believe that our NEO compensation is appropriately sensitive to company financial performance, 
individual performance and long-term shareholder returns.  A more complete discussion of pay 
and performance alignment begins after this Executive Summary. 

2011 total NEO compensation declined 48% for our CEO, and 39%-41% for the other NEOs from 
2010.  These declines are calculated on a grant date fair value basis, and do not align with the 
Summary Compensation Table due to the timing of year-end equity awards and the disclosure 
requirements. 

Annual incentive compensation was earned at approximately 170% of target, based on exceeding our 

Adjusted EBITDA (AEBITDA) target as defined below. 

The grant date value of 2011 NEO equity awards was more than 55% lower than 2010 awards.  These 

awards were granted in February 2012. 

The realizable value of cumulative equity awards made to our CEO in the 5-year period since 2007 
declined by $3.6 million in 2011.  Since 2007, our CEO has received option, performance share 
unit, and restricted share unit awards with a cumulative grant-date fair value of $10.2 million.  As 
of December 31, 2011, the realizable value of these awards was $0.9 million. 

2011 Say-on-Pay Vote 

The advisory vote on NEO compensation at our 2011 annual meeting received 86% favorable votes 

from our shareholders.  The Compensation Committee believes that this result generally affirmed shareholder 
support of the Company’s approach to NEO compensation. 

The Compensation Committee is committed to ensuring that the compensation programs for which 
they are responsible are consistent with the company’s pay for performance policy, and delivers appropriate 
results given performance and business conditions.  Shareholder feedback through this advisory vote will 
remain an important input into the Compensation Committee’s work on compensation design and disclosure. 

Changes to Compensation Programs in 2011 

Several changes were made to NEO compensation programs based on the business highlights noted 

above and feedback around specific elements to the compensation program from shareholders and their 
advisory groups. 

All employees, including the NEOs, were eligible for special payouts in addition to the regular annual 
cash incentive opportunity.  Such a payout was earned in 2010 but not in 2011.  The maximum 
annual incentive award in 2011 is 200% of each NEOs target amount. 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-46- 

 
 
We clarified the manner in which we use competitive market information for NEO benchmarking.  
Previously, we had a stated policy of targeting median for base salary and 75th percentile for 
target cash compensation and long-term incentives.  Upon further analysis, the Compensation 
Committee concluded that this rigid policy does not reflect how the information is actually used. 

o  A stated percentile positioning does not reflect differences in individual NEO responsibilities 

at Rambus compared to available benchmarks and does not reflect how equity award 
decisions are made. 

o  Benchmarking information at the median and 75th percentile is still considered by the 

Compensation Committee, but actual decisions about total compensation, particularly equity 
compensation, are based on a complete assessment, including individual and company 
performance. 

o 

In 2011, annual cash compensation (salary plus annual cash incentive) was closer to the 
market 75th percentile, and equity incentive awards granted in February 2012 (reflecting 2011 
total compensation) were well below the 75th percentile market reference points. 

We enhanced our proxy disclosure to increase transparency and ensure a comprehensive 

understanding of our compensation programs. 

Compensation-Related Shareholder Proposals (See specific proposals for additional details) 

2006 Equity Incentive Plan Amendment (Proposal 3): We are requesting that our shareholders 

authorize an additional 6,500,000 shares to be used for equity awards to employees and directors.  
This is a regularly-scheduled request based on our practice of granting equity as a portion of 
annual compensation to eligible employees.  Our annual dilution from equity awards is well 
below peer median levels (see History Annual Burn Rate on page 69).  We will continue to use 
the equity authorized for compensation purposes in a responsible manner. 

Option Exchange Program (Proposal 5): We believe that our market value has been recalibrated with 
the removal of speculative activity in our stock based on certain litigation outcomes in the past 
year.  A significant majority of employee options outstanding have exercise prices well above the 
current market price of our common stock, and provide little retention or incentive value.  As a 
technology company that relies on innovations, employees are our single biggest asset and 
retaining and attracting employees is key to the long term success of our Company.  We are 
proposing an option exchange program to replace existing far-out-of-the-money options with a 
much lower number of at-the-money options to provide incentives to maintain and continue our 
current business momentum.  We have proposed a program that we believe is fair to shareholders 
as well as beneficial to our employees. 

Under the proposed program: 

̶  NEOs, senior executives, and Board of Directors are not eligible to participate. 

̶ 

In aggregate, the fair value of the exchanged options will be approximately equal to the fair 
value of the new options (i.e., “value for value”), resulting in fewer options outstanding. 

̶  Only options with a strike price higher than $14.50 will be eligible for exchange. 

̶  New options will vest over three years, encouraging retention. 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-47- 

 
 
̶  Options tendered in the exchange will be canceled and will not be reissued. 

Compensation and Governance Practices 

The Compensation Committee reviews compensation programs annually to determine whether or not 

they encourage excessive or unnecessary risk-taking.  Their current assessment is that our 
compensation programs do not encourage excessive or unnecessary risk taking. 

We do not provide cash payments upon termination or change-in-control to our NEOs.  Outstanding 
equity awards may vest upon a “double-trigger” termination in the event of a change-in-control. 

We do not provide perquisites or tax gross-ups to any of our executive officers. 

We have stock ownership guidelines for VPs and above.  All of our NEOs meet these guidelines as of 

December 31, 2011. 

We have no employment agreements or multi-year compensation guarantees for any of our NEOs. 

Our annual dilution from equity compensation has been below the 25th percentile of our 

Compensation Peer Group in each of the last four years. 

All employees are prohibited from engaging in hedging transactions in Rambus shares. 

The Compensation Committee reserves the right to reduce or withhold future compensation based on 
any required restatement or adjustment, and to determine the extent to which recovery of prior 
compensation may be pursued in the event of future adjustments caused by fraud on the part of an 
executive of Rambus.  The Compensation Committee will adopt a policy that complies with the 
requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act when such 
rules are promulgated. 

PAY-FOR-PERFORMANCE OVERVIEW 

Our NEO compensation program closely links compensation to company financial performance and 

individual performance through annual cash incentives, and the creation of long-term stockholder value 
through option and restricted stock unit (“RSU”) awards.  More than 60% of total compensation for our NEOs 
during 2011 was subject to future performance by the Company and the individual NEO based on the 
alternative executive compensation approach discussed below.  Additional information about the NEO 
compensation-setting process and the components of NEO pay are addressed in later sections of the CD&A. 

Total Compensation: Opportunity Aligned with Shareholder Experience 

We grant equity awards in February of each year that are based on prior year company and individual 

performance.  For example, equity awarded in February 2012 is considered a piece of 2011 total 
compensation by the Compensation Committee.  Summary Compensation Table reporting requires that 
awards are reported in the fiscal year in which grants are made.  For example, equity awarded in February 
2012 as part of the 2011 compensation decision does not show up in the proxy tables until the following year.  
As such, any assessments of the pay for performance relationship based on values disclosed in the Summary 
Compensation Table are inconsistent with factors influencing Compensation Committee decisions. 

The table below provides an alternative to the Summary Compensation Table, and is consistent with 

how decisions are made by the Compensation Committee.  Specifically, long-term incentive awards in 

2011 10-K & Proxy Combo bannerless FINAL.docx

February of each year are attributed to the prior fiscal year.  When presented on this basis, the correlation 
between pay and performance for NEOs is apparent.

1  Cash incentive earned for fiscal year performance under the Corporate Incentive Plan (CIP). 
2  Reflects RSUs and options granted in the February following the fiscal year for which the awards are representative.  
Equity awards are valued on a fair value basis using the closing share price on the date of grant.  Option values for 
2011 are estimates.  Actual 2011 option values may be different. 

Based on the above table, 2011 total NEO compensation declined 48% for our CEO, and 39%-41% for 

the other NEOs from 2010.   

Annual Incentive Payouts: Aligned with Financial Performance 

We measure our annual financial performance using Adjusted EBITDA (described in more detail in 
the “NEO Compensation Components” section), a non-GAAP measure that we think is the best indicator of 
success in our core businesses and our ability to continue to drive long-term value creation and continued 
growth in the future. 

2011 NEO annual incentive payouts were approximately 170% of target.  Over the past 5 years, we 
observe that the annual cash incentive payouts have been well-aligned with our GAAP revenue and GAAP 
operating income.  The chart below illustrates the alignment of annual GAAP performance and annual 
incentive payouts for our CEO from 2007-2011.

Realizable Value of Equity: Aligned with Shareholder Experience 

Our stock price declined substantially in 2011, despite strong momentum and performance in our 

ongoing business.  We believe that our compensation program for senior executives, including our NEOs, is 
appropriately sensitive to these results.  NEO equity awards for 2011 (granted in February 2012) were over 
55% lower than 2010 awards (granted in February 2011). 

Since the pay mix for our NEOs is heavily weighted towards equity, our NEOs experience similar 

changes in the realizable value of their awards as the share price changes.  Realizable value is defined as the 
value of equity awards as of a given date after grant, rather than the value on the date of grant. Thus, to the 
extent we do not perform for our shareholders, our executives do not benefit from their equity compensation. 

Because of the decline in our share price in 2011, the realizable value of equity awards made to our 

CEO in the 5-year period since 2007 declined by $3.6 million during 2011.  Since 2007, our CEO has 
received option, performance share unit, and restricted share unit awards with a cumulative grant-date fair 
value of $10.2 million.  As of December 31, 2011, the realizable value of these awards was $0.9 million.

NEO COMPENSATION PROCESS 

The Role of the Compensation Committee 

The Compensation Committee is responsible for determining and approving CEO compensation, 

approving compensation recommendations for executive officers and other senior executives, recommending 
to the board changes to the non-employee director compensation program, and approving the overall levels of 
equity to be granted each year, among other duties expressed it its charter.  In performing these duties, the 
Compensation Committee evaluates the performance of the CEO and other senior executives, and reviews and 
evaluates the existing compensation programs.  The Compensation Committee does not delegate authority to 
management for executive compensation decisions. 

The Use of Independent Compensation Consultants 

The Compensation Committee has the authority to obtain advice and assistance from internal or 

external compensation consultant, attorney, accountant, or other advisers.  The Compensation Committee has 
the authority to retain and terminate any adviser, as well as the authority to approve the fees, terms and 
conditions of any such engagement. 

The Compensation Committee uses Semler Brossy Consulting Group, LLC (SBCG) to assist in 
evaluating executive and director compensation.  SBCG reports directly to the Compensation Committee, and 
works collaboratively with management and the Chairperson of the Compensation Committee.  The 
Compensation Committee has directed SBCG to regularly provide independent advice on a number of topics, 
including current trends in executive compensation design, overall levels of compensation, the merits of using 
particular forms of compensation, the relative weighting of different compensation elements, and the value of 
particular performance measures on which to base compensation for all the NEOs.  SBCG also prepares 
specific material and analyses for the Compensation Committee on CEO compensation.  SBCG has not 
performed, and does not currently have any other consulting engagements with management, or the Company.  
The Compensation Committee evaluates the services provided by SBCG on an annual basis. 

The Role of Management 

The CEO and Senior Vice President of Human Resources present annual performance reviews and 
compensation recommendations for the senior executives (excluding the CEO) for which the Compensation 
Committee has responsibility.  Management personnel also provides support and assistance to the 
Compensation Committee by working with the Compensation Committee’s independent consultant, 
compiling third party reports on compensation data, analyzing peer group data and providing other related 
compensation information and assessments. 

TOOLS USED IN THE COMPENSATION-SETTING PROCESS 

Peer Group Comparisons 

The Compensation Committee analyzes market compensation levels of executives at comparable 

companies to determine whether the total compensation opportunity available to our NEOs is appropriate and 
competitive, and consistent with the Company’s compensation philosophy and objectives.  Each year, SBCG, 
together with senior members of our Human Resources department, defines and assesses the appropriateness 
of a group of similarly situated companies for purposes of this comparison, referred to as the Compensation 
Peer Group.  The Compensation Committee reviews the Compensation Peer Group as recommended by 
management and SBCG, and then approves this group for use in the evaluation of NEO compensation as 
discussed below. 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-51- 

 
 
The 2011 Compensation Peer Group consisted of 18 companies selected based on a number of key 

attributes, including revenue, technological complexity, industry and business characteristics, market 
capitalization and number of employees. 

Altera Corporation 
Applied Micro Circuits Corporation 
Cavium Networks, Inc. 
Cree, Inc. 
Cymer, Inc. 
DSP Group, Inc. 

FormFactor, Inc. 
Integrated Device Technology, Inc. 
InterDigital, Inc. 
MIPS Technologies, Inc. 
OmniVision Technologies, Inc. 
PMC-Sierra, Inc. 

RF Micro Devices, Inc. 
Semtech Corporation 
Silicon Image, Inc. 
Silicon Laboratories Inc. 
Synopsys, Inc. 
Tessera Technologies, Inc. 

External Compensation Data 

The Compensation Committee also reviewed data from the Radford Select Executive Compensation 
Report to supplement the publicly available Compensation Peer Group data.  The Compensation Committee 
considered the information available in the Radford Select Executive Compensation Report to assist in 
establishing NEO compensation by considering industry and general best practices, benchmarks and 
marketplace trends and developments, but without reference to any specific compensation information for any 
individual company included in this report. 

Individual Leadership and Performance Assessments 

The Compensation Committee reviews comprehensive performance assessments of the senior 

executive team, and conducts a review of the CEO performance.  This assessment includes pre-established 
strategic objectives and review of direct feedback from managers, peers and subordinates.  The Compensation 
Committee also holds an annual joint meeting with the Corporate Governance/Nominating Committee to 
review and discuss Company leadership development, performance objectives and emergency and long-term 
succession planning. 

Benchmarking Process 

The Compensation Committee considers several external and internal factors to ensure that 

compensation packages are in line with our pay for performance philosophy and competitive in the market for 
talent.  Market compensation levels and individual leadership and performance assessments as discussed in 
this section are important inputs into the decision-making process.  Additional factors considered include job 
scope, individual skills/experience, relative importance of the individual’s role, internal pay equity, historical 
pay levels and equity holdings, and recent company performance. 

The Compensation Committee reviews median and 75th percentile data as a meaningful input into the 

compensation setting process.  We have historically had a stated policy of targeting median for base salary 
and 75th percentile for target cash compensation and long-term incentives.  Upon further analysis of how this 
information is actually used, the Compensation Committee has determined to not promote a rigid policy about 
pay positioning for several reasons: 

A stated percentile positioning does not reflect differences in individual NEO responsibilities at 

Rambus compared to available benchmarks and does not reflect how equity award decisions are 
made. 

Actual decisions about equity compensation are based on a complete assessment of individual and 

company performance rather than benchmarking results. 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-52- 

 
 
 
For 2011, this resulted in annual cash compensation (salary plus annual cash incentive) that was 

closer to the market 75th percentile, and equity incentive awards granted in February 2012 (reflecting 2011 
total compensation) were well below the 75th percentile market reference points for the NEOs.  The 
Compensation Committee believes this result is appropriate. 

NEO COMPENSATION COMPONENTS 

Annual Base Salary 

The Compensation Committee evaluates base salaries for the NEOs on an annual basis.  The 
Compensation Committee considers a number of factors, including the NEO’s salary history, current 
compensation levels, responsibilities, experience, individual and Company performance, and market 
information when determining and approving NEO salary increases. 

In 2011, the Compensation Committee approved increases in the base salaries for Mr. Hughes, 
Ms. Holt and Dr. Scott.  These increases were made to reflect strong individual performance as well as recent 
market trends. 

2012 salary changes are outlined in the table below. 

Annual Variable Cash Compensation —Corporate Incentive Plan (CIP) 

The CIP provides cash incentives to NEOs based upon the achievement of specific levels of Company 

and individual performance.  The CIP is used for all incentive-eligible employees at the Company.  Target 
opportunity for NEOs under the 2011 CIP was based 70% on Company financial performance and 30% on 
specific predefined individual objectives, commonly referred to as MBOs. 

The Compensation Committee approved increases in target annual cash incentives for all NEOs in 

2011.  These increases were made to reflect strong individual performance and recent market trends.  
Changing target annual cash incentives and leaving salary largely unchanged reflects the commitment to 
using performance-based compensation more heavily. 

For 2012, the Compensation Committee approved increases in target annual cash incentives for all 

NEOs except the CEO.  These increases were made in response to an assessment of internal pay equity 
practices as well as individual performance and contributions.

Company Performance Component – 70% 

We used Adjusted EBITDA (AEBITDA) for the Company performance component of the 2011 CIP1.  
AEBITDA  is  a  non-GAAP  measure  that  consists  of  GAAP  EBITDA,  excluding  litigation  expenses,  stock-
based  compensation  expense,  previous  stock-based  compensation  restatement  and  related  legal  expenses, 
retention bonuses and any CIP related expenses.  One-time or extraordinary expense or income items may be 
excluded  at  the  Compensation  Committee’s  discretion.    The  Company  believes  that  AEBITDA  provides  a 
meaningful  measure  of  core  financial  performance  and  supports  our  short-term  and  long-term  business 
objectives.  2011 threshold, target, and maximum AEBITDA for the CIP were as follows:

Individual Performance Component – 30% 

Each NEO must also achieve certain pre-determined strategic business goals in order to earn the 
MBO component of the CIP.  MBOs ensure that our NEOs continue to deliver on individual operational 
objectives.  MBOs are proposed by senior management personnel and approved annually by the 
Compensation Committee.  The individual MBOs are measured on a quarterly basis. 

The MBO component of the CIP is earned upon achievement and paid quarterly.  Up to 125% of the 
MBO component can be earned regardless of financial performance.  Above 125%, to a maximum of 200%, 
may be earned if AEBITDA performance exceeds target. 

Individual MBOs tie directly to our overall operating plan objectives as approved by the Board of 

Directors annually.  2011 MBOs for NEOs were tied to one or more of the following strategic business 
objectives: 

1.  Continue to advance our memory technology and expand overall semiconductor position 

2.  Secure past and generate future revenue related to Dynamic Random Access Memory 

3.  Bring first general lighting customer to market and sign at least one other key brand 

4.  Maximize the quality and quantity of our inventions 

5.  Optimize licensing opportunities especially in areas with multiple Rambus technology 

innovations 

6.  Diversify into one or two major businesses beyond semiconductor and lighting and display 

7.  Develop organization and our people for rapid change and increasing complexity 

1  For  2010,  the  Company’s  performance  component  was  measured  and  paid  based  on  the  achievement  of  adjusted  pre-tax  income  (“APTI”).  APTI 
consists  of  GAAP  pre-tax  income  adjusted  to  exclude  litigation  expenses,  certain  acquisition  related  expenses,  stock-based  compensation  expense, 
previous stock-based compensation restatement and related legal expenses, and any CIP related expenses. One time or any extraordinary expense or 
income items may also be excluded at the Compensation Committee’s discretion.

2011 CIP Payouts 

2011 AEBITDA was $177.4 million, above the annual target of $141.7 million.  Resulting CIP 

payouts were approximately 170% of target for the NEOs, including the impact of individual MBO 
performance.

Additional CIP Opportunity – Strategic Objectives 

Additional cash opportunity was available to all employees in 2011 based on the achievement of pre-

determined strategic objectives, with payout levels and objectives approved by the Compensation Committee.  
The goals under this plan were not achieved in 2011 and no payouts were made.  The Compensation 
Committee eliminated this plan for 2012. 

We believe that the disclosure of the specific strategic objectives could result in significant 

competitive harm by revealing key elements of our business strategy.  The objectives were based on the 
achievement of objective and quantifiable financial results.  Each special strategic goal was tied to a defined 
event that was expected to significantly strengthen the Company’s operating results and financial 
performance, positioning for future performance, and the ability to execute successfully on the licensing 
platform and business model. 

For each of the two strategic goals, there were threshold, target, and maximum performance 
objectives that would have yielded 50%, 100%, and 200% of each NEO’s annual CIP target, respectively.  
Payment of awards under this special strategic component of the 2011 CIP for our NEOs would have been 
made in equal installments in the two annual periods following achievement of the objectives. 

Equity Compensation 

The Compensation Committee reviews market information, external competitive circumstances, 

overall ownership and vesting schedules of existing equity held by the NEO, and each NEO’s performance 
and contribution during the completed fiscal year to determine annual equity awards. 

The Compensation Committee evaluates annually the structure of the equity compensation program, 
including the vehicles used and the allocation of stock options and restricted stock units to ensure that grants 
appropriately support our strategic and financial objectives. 

 NEO equity awards granted in February 2011 consisted of 75% in stock options and  25% in RSUs.  

The Compensation Committee believes this allocation appropriately balances incentives for growth in share 
price versus the retention encouraged by RSUs.  Options granted in 2011 vest over 5 years and options 
granted in 2012 vest over 4 years. RSUs granted in 2011 and 2012 vest ratably over 4 years. 

The Compensation Committee maintained the 75% option / 25% RSU allocation for the total value of 

the equity awards made in February 2012 for 2011 performance.  2012 grants reflected a decrease in grant-
date fair value of over 55% versus 2011.  In determining these grants, the Compensation Committee

considered a number of factors, consistent with the approach described above, including particular focus on 
the recent stock price decrease.

OTHER POLICIES AND ELEMENTS OF NEO COMPENSATION 

Benefits 

We do not provide any perquisites to NEOs that are not generally available to the broad employee 
population.  This includes supplemental pension arrangements, post-retirement health coverage, or private 
aircraft benefits.  Our NEOs are eligible to participate in our 401(k) plan, our health and welfare benefits, and 
our Employee Stock Purchase Plan on the same terms as other participating employees. 

Stock Ownership Guidelines 

Our senior executives are expected to accumulate and hold a minimum level of common stock 
throughout their tenure at Rambus.  The required levels are 5x base salary for the CEO and 3x base salary for 
the other NEOs3.  Executives have five years to achieve their required level of ownership from the date that 
they become covered by the policy.  Elements that qualify towards ownership goals include shares owned 
outright, unvested restricted stock and restricted stock units, the intrinsic value of vested and unexercised 
stock options, and shares acquired under our Employee Stock Purchase Plan.  As of December 31, 2011, all of 
our NEOs had met their ownership requirements. 

Hedging 

All employees are prohibited from engaging in hedging transactions in Rambus shares. 

2  Equity  usage  rate  is  calculated  by  dividing  (a)  the  sum  of  all  equity  awards  granted  and  equity  awards  assumed  (without  taking  into  account 
cancellations) by (b) the total outstanding shares of common stock on the measurement date.  A conversion factor of 1.5x is used for any full value 
awards, which would include any restricted stock awards or restricted stock units, when determining the sum of all equity awards granted for purposes 
of the calculation.  
3 Elements that will qualify towards ownership goals will include: the value of vested and unvested restricted stock and restricted stock units, vested 
and unexercised stock options, shares acquired under our Employee Stock Purchase Plan and any other shares of common stock owned outright.

Equity Grant Policy 

Annual equity awards are granted on February 1st of each year.  If February 1st is not a trading day, 
the grants become effective and are priced as of the next trading day.  The number of shares and key award 
terms of awards to Section 16 officers are approved by the Compensation Committee prior to the February 1st 
award date. 

Compensation Recovery 

The Compensation Committee reserves the right to reduce or withhold future compensation based on 
any required restatement or adjustment, and to determine the extent to which recovery of prior compensation 
may be pursued in the event of future adjustments caused by fraud on the part of an executive of Rambus.  
The Compensation Committee will adopt a policy that complies with the requirements of the Dodd-Frank 
Wall Street Reform and Consumer Protection Act when such rules are promulgated. 

Tax Considerations 

The Compensation Committee considers the potential future effects of Section 162(m) of the Internal 
Revenue Code of 1986, as amended, when determining NEO compensation.  All of the stock options granted 
to our NEOs are intended to qualify under Section 162(m) as performance-based compensation.  However, 
earned restricted stock units and annual variable cash awards paid to our NEOs under our current annual 
incentive plan may not be deductible as these awards may not qualify as “performance-based compensation” 
for purposes of Section 162(m).  The Compensation Committee intends to continue evaluating all of our 
executive compensation and will qualify such compensation as performance based compensation under 
Section 162(m) to the extent applicable, and so long as the Compensation Committee determines that doing 
so is in the Company’s best interests. 

       Compensation Program Risk Evaluation 

The Compensation Committee reviewed the elements of named executive compensation to determine 
whether any portion of the overall program encouraged excessive risk taking.  Following this assessment, the 
Compensation Committee believes that, although the majority of compensation provided to our named 
executive officers is performance-based, our compensation programs do not encourage excessive or 
unnecessary risk taking. We believe that the design of these compensation programs encourage our named 
executive officers to remain focused on both short-term and long-term strategic goals. 

COMPENSATION COMMITTEE REPORT 

Our Compensation Committee has reviewed and discussed the Compensation Discussion and 
Analysis with management and, based on such review and discussions, the Compensation Committee 
recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this 
report.

(1)  Amounts shown do not reflect compensation actually received by the named executive officer.  Instead, the amounts shown are the aggregate 

grant date fair value computed in accordance with the provisions of FASB ASC Topic 718.  The assumptions used to calculate the value of stock 
and stock option awards are set forth under Note 9 of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-
K for the year ended December 31,  2011. 

(2)  Amounts for fiscal year 2011 consist of compensation earned for services rendered in fiscal year 2011 and are based upon the achievement of 
certain targets under the 2011 Corporate Incentive Plan targets.  The target and achievement results were reviewed and approved by the 
Compensation Committee.  The plan is further described under “Compensation Discussion & Analysis — Executive Compensation 
Components.” 
In addition to any specific other compensation disclosed with respect to individual named executive officers, amounts reported in the “All Other 
Compensation” column for 2011 and previous years consist of matching contributions to the named executive officers’ 401(k) accounts and 
premiums paid for health and welfare insurance policies.

(1)   Amounts shown are estimated payouts for fiscal year  2011 to the named executive officers based on the  2011 bonus targets under the plan discussed under 

“Compensation Discussion & Analysis — Executive Compensation Components.” Actual bonuses received by these named executive officers for fiscal  2011 are 
reported in the Summary Compensation for Fiscal Year  2011 table under the column entitled  “Non-Equity Incentive Plan Compensation” and described under 
“Compensation Discussion & Analysis — Executive Compensation Components ” 

(2)   Restricted stock units granted to all named executives on February 1, 2011. 
(3)   The stock options were granted as part of the Company’s regular performance review process and vest based on the executive continuing to provide services to the 

company through the applicable vesting dates.  See the “Compensation Discussion and Analysis” and “Outstanding Equity Awards at Fiscal Year-End” for additional 
information with respect to these stock option grants. 

(4)   The value of a stock award or stock option award is based on the fair market value as of the grant date of such award determined pursuant to FASB ASC Topic 718. 

Stock awards consist of restricted stock unit awards.  The exercise price for all options granted to the named executive officers is 100% of the fair market value of the 
shares on the grant date.  The option exercise price has not been deducted from the amounts indicated above.  Regardless of the value placed on a stock option on the 
grant date, the actual value of the option will depend on the market value of our Common Stock at such date in the future when the option is exercised exceeds the 
exercise price.

Each of the options and other equity awards reflected on the table above were issued under the 1997 

Plan, the 1999 Plan or the 2006 Plan, which are plans that were or are available to all of our employees. 

In the case of the 1997 Plan and the 1999 Plan, if a “merger” of the Company occurs, as defined in 
the relevant plan, each outstanding option or equity award will be assumed or an equivalent option or right 
substituted by the successor company.  Following such assumption or substitution, if the participant’s status 
as a service provider is terminated by the successor corporation as a result of an “involuntary termination” 
other than for “cause,” each as defined in the relevant plan, within twelve months following the merger, then 
the participant will fully vest and have the right to exercise all of his or her options and will convert any other 
equity awards into shares of Common Stock (commonly referred to as a “double-trigger” termination).  In the 
event that the successor company refuses to assume or substitute for the equity award the participant will fully 
vest in and have the right to exercise all of his or her options or stock appreciation rights, including shares as 
to which such awards would not otherwise be vested or exercisable, all restrictions on restricted stock will 
lapse, and, with respect to restricted stock units, performance shares and performance units, all performance 
goals or other vesting criteria will be deemed achieved at target levels and all other terms and conditions met 
immediately prior to the merger. 

In the case of the 2006 Plan, in the event of a “change of control” of the Company, as defined in the 
plan, each outstanding option or equity award will be assumed or an equivalent option or right substituted by 
the successor company.  In the event that the successor company refuses to assume or substitute for the option 
or equity award, the participant will fully vest in and have the right to exercise all of his or her options or 
stock appreciation rights, including shares as to which such awards would not otherwise be vested or 
exercisable, all restrictions on restricted stock will lapse, and, with respect to restricted stock units, 
performance shares and performance units, all performance goals or other vesting criteria will be deemed 
achieved at target levels and all other terms and conditions met.  In addition, if an option or stock appreciation 
right becomes fully vested and exercisable in lieu of assumption or substitution in the event of a change of 
control, the administrator of the 2006 Plan will notify the participant that the option or stock appreciation 
right will be fully vested and exercisable for a period of time determined by the administrator, and the option 
or stock appreciation right will terminate upon the expiration of such period. 

The form of option agreement for the 2006 Plan provides that if a successor company assumes 
outstanding options or substitutes for options with an equivalent award, then if following such assumption or 
substitution the participant’s status as an employee or employee of the successor company, as applicable, is 
terminated by the successor company as a result of an Involuntary Termination (as defined below) other than 
for Cause (as defined below) within twelve months following the change in control, the option will 
immediately vest and become exercisable as to 100% of the shares subject to the option. 

For purposes of the 2006 Plan form option agreement, “Cause” will mean (i) any act of personal 

dishonesty taken by the participant in connection with his or her responsibilities as an employee and intended 
to result in substantial personal enrichment of the participant, (ii) the participant’s conviction of a felony, 
(iii) a willful act by the participant which constitutes gross misconduct and which is injurious to the successor 
company, and (iv) following delivery to the participant of a written demand for performance from the 
successor company which describes the basis for the successor company’s belief that the participant has not 
substantially performed his or her duties, continued violations by the participant of the participant ’s 
obligations to the successor company which are demonstrably willful and deliberate on the participant’s part. 

For purposes of the 2006 Plan form option agreement, any of the following events shall constitute an 
“Involuntary Termination”: (i) without the participant’s express written consent, a significant reduction of the 
participant’s duties, authority or responsibilities, relative to the participant’s duties, authority or 
responsibilities as in effect immediately prior to the change in control, or the assignment to the participant of 
such reduced duties, authority or responsibilities; (ii) without the participant’s express written consent, a

-64- 

 
 
substantial reduction, without good business reasons, of the facilities and perquisites (including office space 
and location) available to the participant immediately prior to the change in control; (iii) a reduction by the 
successor company in the base salary of the participant as in effect immediately prior to the change in control; 
(iv) a material reduction by the successor company in the kind or level of employee benefits, including 
bonuses, to which the participant was entitled immediately prior to the change in control with the result that 
the participant’s overall benefits package is significantly reduced; (v) the relocation of the participant to a 
facility or a location more than fifty miles from the participant’s then present location, without the 
participant’s express written consent; (vi) any purported termination of the participant by the successor 
company which is not effected for disability or for Cause, or any purported termination for which the grounds 
relied upon are not valid; or (vii) any act or set of facts or circumstances which would, under California case 
law or statute constitute a constructive termination of the Participant.

Potential Payments Upon Termination or Change-in-Control 

We have no contractual arrangements with our named executive officers that would provide payments 

upon termination or change-in-control.  Outstanding equity awards may vest upon a “double-trigger” 
termination in the event of a change-in-control, as provided under the applicable equity plan and as described 
under the “Outstanding Equity Awards at Fiscal 2011 Year-End” table.  This accelerated vesting applies to all 
awards made under the plans and is not specific to awards made to our named executive officers.  The 
following table summarizes the value of the potential accelerated vesting to each named executive officer 
based on the closing price of our common stock of $7.55 on December 30, 2011 (the last trading day of 2011) 
as reported on the Nasdaq Global Select Market.

Overview of Compensation and Procedures 

No changes were made to our Board pay practices in 2011. 

In 2008, as a result of our annual review of Rambus Board pay practices and competitive positioning, 
changes were recommended and adopted to our Board pay practices.  The Compensation Committee reviewed 
materials from SBCG detailing benchmark and competitive pay practices both within our peer group and 
across public companies in general.  A decision was made to discontinue the annual equity stock option grant 
and replace this award with an annual RSU equity grant with an approximate fair market value equal to 
$160,000 at the time of grant.  Our decision to denominate the annual RSU grant in terms of value instead of 
number of shares will help address year-over-year volatility and provides consistent alignment with our 
Compensation Peer Group.  This revision to the director plan acknowledges their commitment of time and 
consultation and will continue to be benchmarked to industry and peer group compensation practices.

Summary of Director Plan 

Annual Retainer.  Each independent director receives an annual retainer of $40,000 in cash.  The 

Chairpersons of the Board and Audit Committee each receive an additional annual retainer of $25,000.  The 
Chairperson of the Compensation Committee receives an additional annual retainer of $20,000.  The 
Chairperson of the Corporate Governance and Nominating Committee receives an additional annual retainer 
of $10,000.  Each annual retainer is paid in quarterly installments.  The annual retainers were not increased 
for 2011. 

Annual Equity Grant.  Each independent director receives an annual equity grant of such number of 

RSUs with an approximate fair market value equal to $160,000 at the time of grant.  This annual equity grant 
represents a change from the annual equity grant of an option to purchase 20,000 shares of Common Stock 
which the independent directors previously received in 2008.  This change was made after reviewing the 
market data of our competitors and to reflect the time commitments our independent directors are asked to 
make to the Company.  The RSU grants vest in full at the end of a one-year period, subject to the independent 
director continuing to serve through each applicable vesting date.  If the director discontinues service prior to 
the vesting of any RSU grant, the Compensation Committee may, in its discretion, permit such grant to vest 
pro rata for the portion of the year during which such director served. 

Initial Equity Grant.  Any newly elected independent director joining our Board of Directors will 

receive an initial option to purchase 40,000 shares of Common Stock when he or she is first elected as a 
member of the Board.  The term of such options will not exceed ten years.  The option grants vest over a four-
year period, with one-eighth of shares subject to the option vesting six months after the date of grant and the 
remaining shares vesting ratably each month thereafter, subject to the independent director continuing to serve 
through each applicable vesting date. 

Awards granted to the independent directors under the 2006 Plan are generally not transferable, and 

all rights with respect to an award granted to a director or participant generally will be available during a 
director or participant’s lifetime only to the director or participant. 

Each of the options granted to our independent directors was issued under the 1997 Plan or the 2006 

Plan, which are plans that are available to all of our employees.  As described under “Outstanding Equity 
Awards at Fiscal Year-End,” the 1997 Plan provides for certain acceleration upon a “merger” of the 
Company, as defined under the 1997 Plan, and the 2006 Plan provides for certain acceleration upon a “change 
of control” of the Company, as defined under the  2006 Plan.  In addition, with respect to options and any 
other equity awards granted to non-employee directors that are assumed or substituted for upon a change of 
control under the 2006 Plan, if the non-employee director is terminated other than upon a voluntary 
resignation, the options and other equity awards granted to such non-employee director will fully vest and be 
exercisable with respect to 100% of the shares subject to such options and other equity awards. 

Pursuant to stock ownership guidelines adopted by the Board in October 2006 and updated in 
February 2011, each independent director will be expected to accumulate and hold an equivalent value of our 
Common Stock of three times their annual total cash compensation and to achieve this by January 1, 2012 or 
five years from the date that the director joined the Board, whichever is later.  Directors are expected to 
maintain this minimum amount of stock ownership throughout their tenure on the Board.  As of December 31, 
2011, all of our directors met their ownership requirements.

Directors with respect to our audited financial statements for the fiscal 
year ended December 31, 2011, which include our consolidated balance 
sheets as of December 31, 2011 and 2010 and the related consolidated

the letter from PricewaterhouseCoopers LLP required by applicable 
requirements of the Public Company Accounting Oversight Board 
regarding the independent auditor’s communications with us concerning 
independence, as may be modified or supplemented, and has discussed 
with PricewaterhouseCoopers LLP its independence from us. 

Based on the review and discussions referred to above, the Audit 
Committee recommended to the Board of Directors that our audited 
financial statements be included in our Annual Report on Form 10-K for

Stock Subject to the Plan.  Subject to the provisions of Section 15 of the Plan, the maximum 
aggregate number of Shares that may be awarded and sold under the Plan is 21,400,000 Shares.  The Shares 
may be authorized, but unissued, or reacquired Common Stock.   

Full Value Awards.  Any Shares subject to Awards granted with an exercise price less than 
the Fair Market Value on the date of grant of such Awards will be counted against the numerical limits of this 
Section 3 as 1.5 Shares for every one Share subject thereto.  Further, if Shares acquired pursuant to any such 
Award  are  forfeited  or  repurchased  by  the  Company  and  would  otherwise  return  to  the  Plan  pursuant  to 
Section 3(c), 1.5 times the number of Shares so forfeited or repurchased will return to the Plan and will again 
become available for issuance. 

Lapsed  Awards.    If  an  Award  expires  or  becomes  unexercisable  without  having  been 
exercised  in  full,  or,  with  respect  to  Restricted  Stock,  Restricted  Stock  Units,  Performance  Shares  or 
Performance  Units,  is  forfeited  to  or  repurchased  by  the  Company,  the  unpurchased  Shares  (or  for  Awards 
other than Options and Stock Appreciation Rights, the forfeited or repurchased Shares) which were  subject 
thereto will become available for future grant or sale under the Plan (unless the Plan has terminated).  With 
respect to Stock Appreciation Rights, all of the Shares covered by the Award (that is, Shares actually issued 
pursuant  to  a  Stock  Appreciation  Right,  as  well  as  the  Shares  that  represent  payment  of  the  exercise  price) 
shall  cease  to  be  available  under  the  Plan.    However,  Shares  that  have  actually  been  issued  under  the  Plan 
under any Award will not be returned to the Plan and will not become available for future distribution under 
the Plan; provided, however, that if unvested Shares of Restricted Stock, Restricted Stock Units, Performance 
Shares or Performance Units are repurchased by the Company or are forfeited to the Company, such Shares 
will  become  available  for  future  grant  under  the  Plan.    Shares  used  to  pay  the  tax  and  exercise  price  of  an 
Award will not become available for future grant or sale under the Plan.  To the extent an Award under the 
Plan is paid out in cash rather than Shares, such cash payment will not result in reducing the number of Shares 
available for issuance under the Plan.  Notwithstanding the foregoing and, subject to adjustment provided in 
Section 15, the maximum number of Shares that may be issued upon the exercise of Incentive Stock Options 
shall equal the aggregate Share number stated in Section 3(a), plus, to the extent allowable under Section 422 
of the Code, any Shares that become available for issuance under the Plan under this Section 3(c). 

Share Reserve.  The Company, during the term of this Plan, will at all times reserve and keep 

available such number of Shares as will be sufficient to satisfy the requirements of the Plan.

General  Administration;  Multiple  Administrative  Bodies.    The  Plan  will  be 
administered by a Committee or Committees as determined by the Board, which will be constituted to satisfy 
Applicable Laws.  Different Committees with respect to different groups of Service Providers may administer

Eligibility.  Nonstatutory Stock Options, Restricted Stock, Restricted Stock Units, Stock Appreciation 
Rights,  Performance  Units,  Performance  Shares  and  such  other  cash  or  stock  awards  as  the  Administrator 
determines may be granted to Service Providers.  Incentive Stock Options may be granted only to Employees. 

Stock Options. 

Limitations.  Each Option will be designated in the Award Agreement as either an Incentive 
Stock Option or a Nonstatutory Stock Option.  However, notwithstanding such designation, to the extent that 
the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable 
for the first time by the Participant during any calendar year (under all plans of the Company and any Parent 
or Subsidiary) exceeds $100,000, such Options will be treated as Nonstatutory Stock Options.  For purposes 
of  this  Section 6(a),  Incentive  Stock  Options  will  be  taken  into  account  in  the  order  in  which  they  were 
granted.  The Fair Market Value of the Shares will be determined as of the time the Option with respect to 
such Shares is granted. 

Number of Shares.  The Administrator will have complete discretion to determine the number 
of Shares subject to Options granted to any Participant, provided that during any Fiscal Year, no Participant 
will be granted Options covering more than 1,000,000 Shares.  Notwithstanding the foregoing limitation, in 
connection with a Participant’s initial service as an Employee, an Employee may be granted Options covering 
up to an additional 1,000,000 Shares.   

Term  of  Option.    The  Administrator  will  determine  the  term  of  each  Option  in  its  sole 
discretion; provided, however, that the term will be no more than ten (10) years from the date of grant thereof.  
Moreover,  in  the  case  of  an  Incentive  Stock  Option  granted  to  a  Participant  who,  at  the  time  the  Incentive 
Stock Option is granted, owns stock representing more than ten percent (10%) of the total combined voting 
power  of  all  classes  of  stock  of  the  Company  or  any  Parent  or  Subsidiary,  the  term  of  the  Incentive  Stock 
Option will be five (5) years from the date of grant or such shorter term as  may be provided in the Award 
Agreement. 

Option Exercise Price and Consideration. 

Exercise Price.  The per share exercise price for the Shares to be issued pursuant 
to exercise of an Option will be determined by the Administrator, but will be no less than 100% of the Fair 
Market Value per Share on the date of grant.  In addition, in the case of an Incentive Stock Option granted to 
an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten 
percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per 
Share exercise price will be no less than 110% of the Fair Market Value per Share on the date of grant.  The 
exercise price for an Option may not be reduced without the consent of the Company’s stockholders.  This 
will include, without limitation, a repricing of the Option as well as an Option exchange program whereby the 
Participant agrees to cancel an existing Option in exchange for an Option, Stock Appreciation Right or other 
Award. 

Waiting  Period  and  Exercise  Dates.    At  the  time  an  Option  is  granted,  the 
Administrator will fix the period within which the Option may be exercised and will determine any conditions 
that must be satisfied before the Option may be exercised. 

Form of Consideration.  The Administrator will determine the acceptable form(s) 
of  consideration  for  exercising  an  Option,  including  the  method  of  payment,  to  the  extent  permitted  by 
Applicable Laws.   

Exercise of Option. 

2011 10-K & Proxy Combo bannerless FINAL.docx

Procedure for Exercise; Rights as a Stockholder.  Any Option granted hereunder 
will  be  exercisable  according  to  the  terms  of  the  Plan  and  at  such  times  and  under  such  conditions  as 
determined by the Administrator and set forth in the Award Agreement.  An Option may not be exercised for 
a fraction of a Share. 

An  Option  will  be  deemed  exercised  when  the  Company  receives:  (i) notice  of 
exercise (in such form as the Administrator specify from time to time) from the person entitled to exercise the 
Option, and (ii) full payment for the Shares with respect to which the Option is exercised (together with an 
applicable withholding taxes).  No adjustment will be made for a dividend or other right for which the record 
date is prior to the date the Shares are issued, except as provided in Section 15 of the Plan. 

Termination of Relationship as a Service Provider.  If a Participant ceases to be a 
Service Provider, other than upon the Participant’s death or Disability, the Participant may exercise his or her 
Option  within  such  period  of  time  as  is  specified  in  the  Award  Agreement  to  the  extent  that  the  Option  is 
vested on the date of termination (but in no event later than the expiration of the term of such Option as set 
forth in the Award Agreement).  In the absence of a specified time in the Award Agreement, the Option will 
remain exercisable for three (3) months following the Participant’s termination.  Unless otherwise provided 
by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, 
the  Shares  covered  by  the  unvested  portion  of  the  Option  will  revert  to  the  Plan.    If  after  termination  the 
Participant does not exercise his or her Option within the time specified by the Administrator, the Option will 
terminate, and the Shares covered by such Option will revert to the Plan. 

Disability  of  Participant.    If  a  Participant  ceases  to  be  a  Service  Provider  as  a 
result of the Participant’s Disability, the Participant may exercise his or her Option within such period of time 
as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in no 
event  later  than  the  expiration  of  the  term  of  such  Option  as  set  forth  in  the  Award  Agreement).    In  the 
absence  of  a  specified  time  in  the  Award  Agreement,  the  Option  will  remain  exercisable  for  twelve  (12) 
months  following  the  Participant’s  termination.    Unless  otherwise  provided  by  the  Administrator,  if  on  the 
date  of  termination  the  Participant  is  not  vested  as  to  his  or  her  entire  Option,  the  Shares  covered  by  the 
unvested portion of the Option will revert to the Plan.  If after termination the Participant does not exercise his 
or  her  Option  within  the  time  specified  herein,  the  Option  will  terminate,  and  the  Shares  covered  by  such 
Option will revert to the Plan. 

Death of Participant.  If a Participant dies while a Service Provider, the Option 
may  be  exercised  following  the  Participant’s  death  within  such  period  of  time  as  is  specified  in  the  Award 
Agreement  to  the  extent  that  the  Option  is  vested  on  the  date  of  death  (but  in  no  event  may  the  option  be 
exercised later than the expiration of the term of such Option as set forth in the Award Agreement), by the 
Participant’s  designated  beneficiary,  provided  such  beneficiary  has  been  designated  prior  to  Participant’s 
death  in  a  form  acceptable  to  the  Administrator.    If  no  such  beneficiary  has  been  designated  by  the 
Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by 
the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the 
laws of descent and distribution.  In the absence of a specified time in the Award Agreement, the Option will 
remain exercisable for twelve (12) months following Participant’s death.  Unless otherwise provided by the 
Administrator,  if  at  the  time  of  death  Participant  is  not  vested  as  to  his  or  her  entire  Option,  the  Shares 
covered  by  the  unvested  portion of  the  Option  will  immediately  revert  to  the  Plan.    If  the  Option  is  not  so 
exercised within the time specified herein, the Option will terminate, and the Shares covered by such Option 
will revert to the Plan.

Restricted Stock. 

Grant of Restricted Stock.  Subject to the terms and provisions of the Plan, the Administrator, 
at any time and from time to time, may grant Shares of Restricted Stock to Service Providers in such amounts 
as the Administrator, in its sole discretion, will determine. 

Restricted Stock Agreement.  Each Award of Restricted Stock will be evidenced by an Award 
Agreement that will specify the Period of Restriction, the number of Shares granted, and such other terms and 
conditions  as  the  Administrator,  in  its  sole  discretion,  will  determine.    Notwithstanding  the  foregoing 
sentence,  during  any  Fiscal  Year  no  Participant  will  receive  more  than  an  aggregate  of  200,000  Shares  of 
Restricted Stock; provided, however, that in connection with a Participant’s initial service as an Employee, an 
Employee may be granted an aggregate of up to an additional 300,000 Shares of Restricted Stock.  Unless the 
Administrator determines otherwise, Shares of Restricted Stock will be held by the Company as escrow agent 
until the restrictions on such Shares have lapsed. 

Transferability.  Except as provided in this Section 7, Shares of Restricted Stock may not be 
sold,  transferred,  pledged,  assigned,  or  otherwise  alienated  or  hypothecated  until  the  end  of  the  applicable 
Period of Restriction. 

Other  Restrictions.    The  Administrator,  in  its  sole  discretion,  may  impose  such  other 

restrictions on Shares of Restricted Stock as it may deem advisable or appropriate. 

Removal of Restrictions.  Except as otherwise provided in this Section 7, Shares of Restricted 
Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as 
practicable after the last day of the Period of Restriction.  The Administrator, in its discretion, may accelerate 
the  time  at  which  any  restrictions  will  lapse  or  be  removed;  provided,  however,  Shares  of  Restricted  Stock 
will not vest more rapidly than one-third (1/3rd) of the total number of Shares of Restricted Stock subject to an 
Award each year from the date of grant, unless the Administrator determines that the Award is to vest upon 
the  achievement  of  performance  criteria  and  the  period  for  measuring  such  performance  will  cover  at  least 
twelve  (12)  months;  provided,  further,  that  the  Administrator  may  grant  Awards  of  Restricted  Stock, 
Restricted  Stock  Units  and  Performance  Units/Shares  covering  up  to  5%  of  the  total  number  of  Shares 
reserved for issuance under the Plan that do not satisfy the forgoing vesting requirements.  Notwithstanding 
the foregoing sentence, the Administrator, in its sole discretion, may provide at the time of or following the 
date of grant for accelerated vesting for an Award of Restricted Stock (provided, however, that the number of 
Shares subject or issuable pursuant to Awards of Restricted Stock, Restricted Stock Units and Performance 
Units/Shares eligible for such accelerated vesting shall not exceed 5% of the total number of Shares reserved 
for  issuance  under  the  Plan)  or  for  accelerated  vesting  upon  or  in  connection  with  a  Change  in  Control 
(including  any  vesting  acceleration  provided  for  in  Section  15(c))  or  upon  or  in  connection  with  a 
Participant’s termination of service due to death, Disability or retirement.   

Voting  Rights.    During  the  Period  of  Restriction,  Service  Providers  holding  Shares  of 
Restricted  Stock  granted  hereunder  may  exercise  full  voting  rights  with  respect  to  those  Shares,  unless  the 
Administrator determines otherwise. 

Dividends  and  Other  Distributions.    During  the  Period  of  Restriction,  Service  Providers 
holding Shares of Restricted Stock will be entitled to receive all dividends and other distributions paid with 
respect  to  such  Shares  unless  otherwise  provided  in  the  Award  Agreement.    If  any  such  dividends  or 
distributions  are  paid  in  Shares,  the  Shares  will  be  subject  to  the  same  restrictions  on  transferability  and 
forfeitability as the Shares of Restricted Stock with respect to which they were paid.

Return of Restricted Stock to Company.  On the date set forth in the Award Agreement, the 
Restricted  Stock  for  which  restrictions  have  not  lapsed  will  revert  to  the  Company  and  again  will  become 
available for grant under the Plan. 

Restricted Stock Units. 

Grant.    Restricted  Stock  Units  may  be  granted  at  any  time  and  from  time  to  time  as 
determined  by  the  Administrator.    Each  Restricted  Stock  Unit  grant  will  be  evidenced  by  an  Award 
Agreement that will specify such other terms and conditions as the Administrator, in its sole discretion, will 
determine, including all terms, conditions, and restrictions related to the grant, the number of Restricted Stock 
Units  and  the  form  of  payout,  which,  subject  to  Section 8(d),  may  be  left  to  the  discretion  of  the 
Administrator.  Notwithstanding the anything to the contrary in this subsection (a), during any fiscal year of 
the Company, no Participant will receive more than an aggregate of 200,000 Restricted Stock Units; provided, 
however, that in connection with a Participant’s initial service as an Employee, an Employee may be granted 
an aggregate of up to an additional 300,000 Restricted Stock Units. 

Vesting  Criteria  and  Other  Terms.    The  Administrator  will  set  vesting  criteria  in  its 
discretion,  which,  depending  on  the  extent  to  which  the  criteria  are  met,  will  determine  the  number  of 
Restricted Stock Units that will be paid out to the Participant.  Each Award of Restricted Stock Units will be 
evidenced by an Award Agreement that will specify the vesting criteria, and such other terms and conditions 
as the Administrator, in its sole discretion, will determine; provided, however, that, an Award of Restricted 
Stock  Units  will  not  vest  more  rapidly  than  one-third  (1/3rd)  of  the  total  number  of  Restricted  Stock  Units 
subject to an Award each year from the date of grant, unless the Administrator determines that the Award is to 
vest upon the achievement of performance criteria and the period for measuring such performance will cover 
at least twelve (12) months; provided, further, that the Administrator may grant Awards of Restricted Stock, 
Restricted  Stock  Units  and  Performance  Units/Shares  covering  up  to  5%  of  the  total  number  of  Shares 
reserved for issuance under the Plan that do not satisfy the forgoing vesting requirements.  Notwithstanding 
the foregoing sentence, the Administrator, in its sole discretion, may provide at the time of or following the 
date  of  grant  for  accelerated  vesting  for  an  Award  of  Restricted  Stock  Units  (provided,  however,  that  the 
number  of  Shares  subject  or  issuable  pursuant  to  Awards  of  Restricted  Stock,  Restricted  Stock  Units  and 
Performance  Units/Shares  eligible  for  such  accelerated  vesting  shall  not  exceed  5%  of  the  total  number  of 
Shares reserved for issuance under the Plan) or for accelerated vesting upon or in connection with a Change in 
Control  (including  any  vesting  acceleration  provided  for  in  Section  15(c))  or  upon  or  in  connection  with  a 
Participant’s termination of service due to death, Disability or retirement. 

Earning Restricted Stock Units.  Upon meeting the applicable vesting criteria, the Participant 
will be entitled to receive a payout as specified in the Award Agreement.  Notwithstanding the foregoing, at 
any  time  after  the  grant  of  Restricted  Stock  Units,  the  Administrator,  in  its  sole  discretion,  may  reduce  or 
waive any vesting criteria that must be met to receive a payout.   

Form  and  Timing  of  Payment.    Payment  of  earned  Restricted  Stock  Units  will  be  made  as 
soon  as  practicable  after  the  date(s)  set  forth  in  the  Award  Agreement.    The  Administrator,  in  its  sole 
discretion,  may  pay  earned  Restricted  Stock  Units  in  cash,  Shares,  or  a  combination  thereof.    Shares 
represented by Restricted Stock Units that are fully paid in cash again will be available for grant under the 
Plan. 

Cancellation.  On the date set forth in the Award Agreement, all unearned Restricted Stock 

Units will be forfeited to the Company.

Grant of Stock Appreciation Rights.  Subject to the terms and conditions of the Plan, a Stock 
Appreciation  Right  may  be  granted  to  Service  Providers  at  any  time  and  from  time  to  time  as  will  be 
determined by the Administrator, in its sole discretion.   

Number of Shares.  The Administrator will have complete discretion to determine the number 
of Stock Appreciation Rights granted to any Participant, provided that during any Fiscal Year, no Participant 
will  be  granted  Stock  Appreciation  Rights  covering  more  than  1,000,000  Shares.    Notwithstanding  the 
foregoing limitation, in connection with a Participant’s initial service as an Employee, an Employee may be 
granted Stock Appreciation Rights covering up to an additional 1,000,000 Shares. 

Exercise  Price  and  Other  Terms.    The  Administrator,  subject  to  the  provisions  of  the  Plan, 
will  have  complete  discretion  to  determine  the  terms  and  conditions  of  Stock  Appreciation  Rights  granted 
under the Plan, provided, however, that the exercise price will be not less than one hundred percent (100%) of 
the Fair Market Value of a Share on the date of grant.  The exercise price for a Stock Appreciation Right may 
not be reduced without the consent of the Company’s stockholders.  This will include, without limitation, a 
repricing of the Stock Appreciation Right as well as an exchange program whereby the Participant agrees to 
cancel  an  existing  Stock  Appreciation  Right  in  exchange  for  an  Option,  Stock  Appreciation  Right  or  other 
Award. 

Stock  Appreciation  Right  Agreement.    Each  Stock  Appreciation  Right  grant  will  be 
evidenced  by  an  Award  Agreement  that  will  specify  the  exercise  price,  the  term  of  the  Stock  Appreciation 
Right,  the  conditions  of  exercise,  and  such  other  terms  and  conditions  as  the  Administrator,  in  its  sole 
discretion, will determine. 

Expiration of Stock Appreciation Rights.  A Stock Appreciation Right granted under the Plan 
will expire upon the date determined by the Administrator, in its sole discretion, and set forth in the Award 
Agreement;  provided,  however,  that  the  term  will  be  no  more  than  ten (10)  years  from  the  date  of  grant 
thereof.    Notwithstanding  the  foregoing,  the  rules  of  Section 6(e)  also  will  apply  to  Stock  Appreciation 
Rights. 

Payment of Stock Appreciation Right Amount.  Upon exercise of a Stock Appreciation Right, 

a Participant will be entitled to receive payment from the Company in an amount determined by multiplying: 

over the exercise price; times 

The difference between the Fair Market Value of a Share on the date of exercise 

exercised. 

The  number  of  Shares  with  respect  to  which  the  Stock  Appreciation  Right  is 

At the discretion of the Administrator, the payment upon Stock Appreciation Right exercise may be in cash, 
in Shares of equivalent value, or in some combination thereof. 

Performance Units and Performance Shares. 

Grant  of  Performance  Units/Shares.    Performance  Units  and  Performance  Shares  may  be 
granted to Service Providers at any time and from time to time, as will be determined by the Administrator, in 
its  sole  discretion.    The  Administrator  will  have  complete  discretion  in  determining  the  number  of 
Performance Units/Shares granted to each Participant provided that during any Fiscal Year, (i) no Participant 
will  receive  Performance  Units  having  an  initial  value  greater  than  $2,000,000,  and  (ii)  no  Participant  will 
receive more than 200,000 Performance Shares.  Notwithstanding the foregoing limitation, in connection with 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-81- 

 
 
a  Participant’s  initial  service  as  an  Employee,  an  Employee  may  be  granted  up  to  an  additional  300,000 
Performance Shares. 

Value of Performance Units/Shares.  Each Performance Unit will have an initial value that is 
established by the Administrator on or before the date of grant.  Each Performance Share will have an initial 
value equal to the Fair Market Value of a Share on the date of grant. 

Performance Objectives and Other Terms.  The Administrator will set performance objectives 
or  other  vesting  provisions  (including,  without  limitation,  continued  status  as  a  Service  Provider)  in  its 
discretion  which,  depending  on  the  extent  to  which  they  are  met,  will  determine  the  number  or  value  of 
Performance Units/Shares that will be paid out to the Participant.  Each Award of Performance Units/Shares 
will be evidenced by an Award Agreement that will specify the Performance Period, and such other terms and 
conditions  as  the  Administrator,  in  its  sole  discretion,  will  determine;  provided,  however,  that  Performance 
Units/Shares will not vest more rapidly than one-third (1/3rd) of the total number of Performance Units/Shares 
subject to an Award each year from the date of grant, unless the Administrator determines that the Award is to 
vest upon the achievement of performance criteria and the period for measuring such performance will cover 
at least twelve (12) months; provided, further, that the Administrator may grant Awards of Restricted Stock, 
Restricted  Stock  Units  and  Performance  Units/Shares  covering  up  to  5%  of  the  total  number  of  Shares 
reserved for issuance under the Plan that do not satisfy the forgoing vesting requirements.  Notwithstanding 
the foregoing sentence, the Administrator, in its sole discretion, may provide at the time of or following the 
date of grant for accelerated vesting for an Award of Performance Units/Shares (provided, however, that the 
number  of  Shares  subject  or  issuable  pursuant  to  Awards  of  Restricted  Stock,  Restricted  Stock  Units  and 
Performance  Units/Shares  eligible  for  such  accelerated  vesting  shall  not  exceed  5%  of  the  total  number  of 
Shares reserved for issuance under the Plan) or for accelerated vesting upon or in connection with a Change in 
Control  (including  any  vesting  acceleration  provided  for  in  Section  15(c))  or  upon  or  in  connection  with  a 
Participant’s termination of service due to death, Disability or retirement. 

Earning  of  Performance  Units/Shares.    After  the  applicable  Performance  Period  has  ended, 
the  holder  of  Performance  Units/Shares  will  be  entitled  to  receive  a  payout  of  the  number  of  Performance 
Units/Shares  earned  by  the  Participant  over  the  Performance  Period,  to  be  determined  as  a  function  of  the 
extent  to  which  the  corresponding  performance  objectives  or  other  vesting  provisions  have  been  achieved.  
After the grant of a Performance Unit/Share, the Administrator,  in its sole discretion,  may reduce or waive 
any performance objectives or other vesting provisions for such Performance Unit/Share. 

Form and Timing of Payment of Performance Units/Shares.  Payment of earned Performance 
Units/Shares  will be  made as soon as practicable  after the expiration of the applicable Performance Period.  
The Administrator, in its sole discretion,  may pay earned Performance Units/Shares in the form of cash, in 
Shares  (which  have  an  aggregate  Fair  Market  Value  equal  to  the  value  of  the  earned  Performance 
Units/Shares at the close of the applicable Performance Period) or in a combination thereof. 

Cancellation of Performance Units/Shares.  On the date set forth in the Award Agreement, all 
unearned or unvested Performance Units/Shares will be forfeited to the Company, and again will be available 
for grant under the Plan. 

Performance  Goals.    The  granting  and/or  vesting  of  Awards  of  Restricted  Stock,  Restricted  Stock 
Units, Performance Shares and Performance Units and other incentives under the Plan may be made subject to 
the attainment of performance goals relating to one or more business criteria within the meaning of Section 
162(m)  of  the  Code  and  may  provide  for  a  targeted  level  or  levels  of  achievement  (“Performance  Goals”) 
including  cash  flow;  cash  position;  earnings  before  interest  and  taxes;  earnings  before  interest,  taxes, 
depreciation  and  amortization;  earnings  per  Share;  economic  profit;  economic  value  added;  equity  or 
stockholder’s  equity;  market  share;  net  income;  net  profit;  net  sales;  operating  earnings;  operating  income;

profit  before  tax;  ratio  of  debt  to  debt  plus  equity;  ratio  of  operating  earnings  to  capital  spending;  sales 
growth; return on net assets; or total return to stockholders.  Any Performance Goals may be used to measure 
the  performance  of  the  Company  as  a  whole  or  an  business  unit  of  the  Company  and  may  be  measured 
relative to a peer group or index.  The Performance Goals may differ from Participant to Participant and from 
Award to Award.  Prior to the Determination Date, the Administrator will determine whether any significant 
element(s) will be included in or excluded from the calculation of any Performance Goal with respect to any 
Participant.    In  all  other  respects,  Performance  Goals  will  be  calculated  in  accordance  with  the  Company’s 
financial  statements,  generally  accepted  accounting  principles,  or  under  a  methodology  established  by  the 
Administrator prior to the issuance of an Award. 

Leaves of Absence.  Unless the Administrator provides otherwise, or except as otherwise required by 
Applicable Laws, vesting of Awards granted hereunder on or after July 17, 2007, will be suspended starting 
on the 30th consecutive day of any unpaid leave of absence approved by the Company, with such suspension 
of vesting terminating upon the Participant’s resumption of service with the Company.  A Service Provider 
will  not  cease  to  be  an  Employee  in  the  case  of  (i) any  leave  of  absence  approved  by  the  Company  or 
(ii) transfers between locations of the Company or between the Company, its Parent, or any Subsidiary.  For 
purposes of Incentive Stock Options, no such leave may exceed ninety (90) days, unless reemployment upon 
expiration of such leave is guaranteed by statute or contract.  If reemployment upon expiration of a leave of 
absence approved by the Company is not so guaranteed, then three (3) months following the 91st day of such 
leave any Incentive Stock Option held by the Participant will cease to be treated as an Incentive Stock Option 
and will be treated for tax purposes as a Nonstatutory Stock Option. 

Transferability of Awards.  Unless determined otherwise by the Administrator, an Award may not be 
sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the 
laws  of  descent  or  distribution  and  may  be  exercised,  during  the  lifetime  of  the  Participant,  only  by  the 
Participant.  If the Administrator makes an Award transferable, such Award will contain such additional terms 
and conditions as the Administrator deems appropriate. 

Awards to Outside Directors 

General.    All  grants  of  Awards  to  Outside  Directors  pursuant  to  this  Section 14  will  be 
automatic  and  nondiscretionary  and  will  be  made  in  accordance  with  the  following  provisions,  except  as 
otherwise provided herein. 

Granting of Awards.   

Initial Award.  Each Outside Director who becomes an Outside Director after the 
effective  date  of  this  Plan  will  be  automatically  granted  a  Nonstatutory  Stock  Option  to  purchase  40,000 
Shares  (the  “Initial  Award”)  on  the  date  on  which  such  person  first  becomes  an  Outside  Director,  whether 
through election by the stockholders of the Company or appointment by the Board to fill a vacancy; provided, 
however,  that  an  Inside  Director  who  ceases  to  be  an  Inside  Director  but  who  remains  a  Director  will  not 
receive an Initial Award.  

Subsequent  Awards.    Each  Outside  Director  will  be  automatically  granted  an 
Award  of  Restricted  Stock  Units  on  October 1  of  each  year;  provided  that  he  or  she  is  then  an  Outside 
Director (a “Subsequent Award”).  The number of Restricted Stock Units subject to the Subsequent Award 
will be determined in the sole discretion of the Board or the Administrator on or prior to the Award becoming 
effective on the applicable October 1 grant date. 

Terms of Initial Award.  The terms of the Initial Award will be as follows:

The term of the Initial Award will be ten (10) years. 

The exercise price per Share will be 100% of the Fair Market Value per Share on 
the date of grant.  In the event that the date of grant is not a trading day, the exercise price per Share will be 
the Fair Market Value on the next trading day immediately following the date of grant. 

Subject to the provisions of Section 15, 12.5% of the Shares subject to the Initial 
Award will vest six (6) months after the date of grant, and 1/48 of the Shares subject to the Initial Award will 
vest  each  month  thereafter  so  that  100%  of  the  Shares  subject  to  the  Initial  Award  will  be  vested  four  (4) 
years  from  the  grant  date,  subject  to  the  Outside  Director  remaining  a  Service  Provider  through  each  such 
vesting date. 

Subsequent Award.  The terms of each Subsequent Award will be as follows: 

Subject  to  the  provisions  of  Section  15,  the  Subsequent  Award  will  vest  and 
become  payable  as  to  100%  of  the  Restricted  Stock  Units  subject  to  the  Award  on  the  twelve  (12)  month 
anniversary of the date of grant, subject to the Outside Director remaining a Service Provider through such 
vesting  date.    Notwithstanding  the  foregoing,  at  any  time  after  the  grant  of  the  Subsequent  Award,  the 
Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a 
payout of the Restricted Stock Units subject to the Subsequent Award. 

conditions of the Plan will apply to any Subsequent Awards. 

To the extent not in conflict with the terms of this Section 14, the other terms and 

Adjustments.  The Administrator in its discretion may change and otherwise revise the terms 
of Awards granted under this Section 14, including, without limitation, the number of Shares and/or the types 
of Awards to be granted, for Awards granted on or after the date the Administrator determines to make any 
such change or revision.   

Other Awards.  Nothing in this Section 14 will limit the ability of the Administrator to grant 
all types of Awards under the Plan (including Options) to Outside Directors in addition to the Awards that are 
granted to them under this Section 14. 

Adjustments; Dissolution or Liquidation; Merger or Change in Control. 

Adjustments.    In  the  event  that  any  dividend  or  other  distribution  (whether  in  the  form  of 
cash,  Shares,  other  securities,  or  other  property),  recapitalization,  stock  split,  reverse  stock  split, 
reorganization,  merger,  consolidation,  split-up,  spin-off,  combination,  repurchase,  or  exchange  of  Shares  or 
other  securities  of  the  Company,  or  other  change  in  the  corporate  structure  of  the  Company  affecting  the 
Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential 
benefits intended to be made available under the Plan, may (in its sole discretion) adjust the number and class 
of Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by each 
outstanding Award, and the numerical Share limits set forth in Sections 3, 6, 7, 8, 9, 10 and 14. 

Dissolution  or  Liquidation.    In  the  event  of  the  proposed  dissolution  or  liquidation  of  the 
Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of 
such  proposed  transaction.    To  the  extent  it  has  not  been  previously  exercised,  an  Award  will  terminate 
immediately prior to the consummation of such proposed action. 

Change  in  Control.    In  the  event  of  a  Change  in  Control,  each  outstanding  Award  will  be 
assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-84- 

 
 
the successor corporation (the “Successor Corporation”).  In the event that the Successor Corporation refuses 
to assume or substitute for the Award, the Participant will fully vest in and have the right to exercise all of his 
or her outstanding Options and Stock Appreciation Rights, including Shares as to which such Awards would 
not  otherwise  be  vested  or  exercisable,  all  restrictions  on  Restricted  Stock  will  lapse,  and,  with  respect  to 
Restricted Stock Units, Performance Shares and Performance Units, all Performance Goals or other vesting 
criteria  will  be  deemed  achieved  at  target  levels  and  all  other  terms  and  conditions  met.    In  addition,  if  an 
Option or Stock Appreciation Right is not assumed or substituted for in the event of a Change in Control, the 
Administrator  will  notify  the  Participant  in  writing  or  electronically  that  the  Option  or  Stock  Appreciation 
Right  will  be  fully  vested  and  exercisable  for  a  period  of  time  determined  by  the  Administrator  in  its  sole 
discretion, and the Option or Stock Appreciation Right will terminate upon the expiration of such period. 

With respect to Awards granted to Outside Directors that are assumed or substituted for, if on 
the date of or following such assumption or substitution the Participant’s status as a Director or a director of 
the  Successor  Corporation,  as  applicable,  is  terminated  other  than  upon  a  voluntary  resignation  by  the 
Participant,  then  the  Participant  will  fully  vest  in  and  have  the  right  to  exercise  Options  and/or  Stock 
Appreciation Rights as to all of the Shares subject thereto, including Shares as to which such Awards would 
not  otherwise  be  vested  or  exercisable,  all  restrictions  on  Restricted  Stock  will  lapse,  and,  with  respect  to 
Restricted Stock Units, Performance Shares and Performance Units, all Performance Goals or other vesting 
criteria will be deemed achieved at target levels and all other terms and conditions met. 

For the purposes of this subsection (c), an Award  will be considered assumed  if, following 
the  Change  in  Control,  the  Award  confers  the  right  to  purchase  or  receive,  for  each  Share  subject  to  the 
Award immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities 
or  property)  or,  in  the  case  of  a  Stock  Appreciation  Right  upon  the  exercise  of  which  the  Administrator 
determines to pay cash or a Performance Share or Performance Unit which the Administrator can determine 
to  pay  in  cash,  the  fair  market  value  of  the  consideration  received  in  the  merger  or  Change  in  Control  by 
holders of Common Stock for each Share held on the effective  date of the transaction (and if holders were 
offered  a  choice  of  consideration,  the  type  of  consideration  chosen  by  the  holders  of  a  majority  of  the 
outstanding Shares); provided, however, that if such consideration received in the Change in Control is not 
solely common stock of the Successor Corporation, the Administrator may, with the consent of the Successor 
Corporation,  provide  for  the  consideration  to  be  received  upon  the  exercise  of  an  Option  or  Stock 
Appreciation Right or upon the payout of a Performance Share or Performance Unit, for each Share subject to 
such Award (or in the case of Performance Units, the number of implied shares determined by dividing the 
value of the Performance Units by the per share consideration received by holders of Common Stock in the 
Change in Control), to be solely common stock of the Successor Corporation equal in fair market value to the 
per share consideration received by holders of Common Stock in the Change in Control. 

Notwithstanding anything in this Section 15(c) to the contrary, an Award that vests, is earned 
or  paid-out  upon  the  satisfaction  of  one  or  more  Performance  Goals  will  not  be  considered  assumed  if  the 
Company  or  its  successor  modifies  any  of  such  Performance  Goals  without  the  Participant’s  consent; 
provided,  however,  a  modification  to  such  Performance  Goals  only  to  reflect  the  Successor  Corporation’s 
post-Change  in  Control  corporate  structure  will  not  be  deemed  to  invalidate  an  otherwise  valid  Award 
assumption. 

Tax Withholding 

Withholding Requirements.  Prior to the delivery of any Shares or cash pursuant to an Award 
(or  exercise  thereof),  the  Company  will  have  the  power  and  the  right  to  deduct  or  withhold,  or  require  a 
Participant to remit to the Company, an amount sufficient to satisfy federal, state, local, foreign or other taxes 
(including the Participant’s FICA obligation) required to be withheld with respect to such Award (or exercise 
thereof).   

2011 10-K & Proxy Combo bannerless FINAL.docx 

-85- 

 
 
Withholding  Arrangements.    The  Administrator,  in  its  sole  discretion  and  pursuant  to  such 
procedures  as  it  may  specify  from  time  to  time,  may  permit  a  Participant  to  satisfy  such  tax  withholding 
obligation,  in  whole  or  in  part  by  (without  limitation)  (a)  paying  cash,  (b) electing  to  have  the  Company 
withhold otherwise deliverable cash or Shares having a Fair Market Value equal to the amount required to be 
withheld,  (c)  delivering  to  the  Company  already-owned  Shares  having  a  Fair  Market  Value  equal  to  the 
amount  required  to  be  withheld,  or  (d)  selling  a  sufficient  number  of  Shares  otherwise  deliverable  to  the 
Participant through such means as the Administrator may determine in its sole discretion (whether through a 
broker or otherwise) equal to the amount required to be withheld.  The amount of the withholding requirement 
will  be  deemed  to  include  any  amount  which  the  Administrator  agrees  may  be  withheld  at  the  time  the 
election is made, not to exceed the amount determined by using the maximum federal, state or local marginal 
income tax rates applicable to the Participant with respect to the Award on the date that the amount of tax to 
be  withheld  is  to  be  determined.    The  Fair  Market  Value  of  the  Shares  to  be  withheld  or  delivered  will  be 
determined as of the date that the taxes are required to be withheld. 

No Effect on Employment or Service.  Neither the Plan nor any Award will confer upon a Participant 
any  right  with  respect  to  continuing  the  Participant’s  relationship  as  a  Service  Provider  with  the  Company, 
nor  will  they  interfere  in  any  way  with  the  Participant’s  right  or  the  Company’s  right  to  terminate  such 
relationship at any time, with or without cause, to the extent permitted by Applicable Laws. 

Date  of  Grant.    The  date  of  grant  of  an  Award  will  be,  for  all  purposes,  the  date  on  which  the 
Administrator makes the determination granting such Award, or such other later date as is determined by the 
Administrator.  Notice of the determination will be provided to each Participant within a reasonable time after 
the date of such grant. 

Term of Plan.  Subject to Section 23 of the Plan, the Plan will become effective upon its adoption by 
the Board.  It will continue in effect for a term of ten (10) years unless terminated earlier under Section 20 of 
the Plan. 

Amendment and Termination of the Plan. 

Amendment and Termination.  The Board or the Administrator may at any time amend, alter, 

suspend or terminate the Plan.   

Stockholder  Approval.    The  Company  will  obtain  stockholder  approval  of  any  Plan 

amendment to the extent necessary and desirable to comply with Applicable Laws.  

Effect of Amendment or Termination.  No amendment, alteration, suspension or termination 
of the Plan will impair the rights of any Participant, unless mutually agreed otherwise between the Participant 
and the Administrator, which agreement must be in writing and signed by the Participant and the Company.  
Termination  of  the  Plan  will  not  affect  the  Administrator’s  ability  to  exercise  the  powers  granted  to  it 
hereunder with respect to Awards granted under the Plan prior to the date of such termination. 

Conditions Upon Issuance of Shares. 

Legal Compliance.  Shares will not be issued pursuant to the exercise of an Award unless the 
exercise of such Award and the issuance and delivery of such Shares will comply with Applicable Laws and 
will be further subject to the approval of counsel for the Company with respect to such compliance. 

Investment Representations.  As a condition to the exercise of an Award, the Company may 
require the person exercising such Award to represent and warrant at the time of any such exercise that the 

2011 10-K & Proxy Combo bannerless FINAL.docx

Shares  are  being  purchased  only  for  investment  and  without  any  present  intention  to  sell  or  distribute  such 
Shares if, in the opinion of counsel for the Company, such a representation is required. 

Inability to Obtain Authority.  The inability of the Company to obtain authority from any regulatory 
body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful 
issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to 
issue or sell such Shares as to which such requisite authority will not have been obtained. 

Stockholder  Approval.    The  Plan  will  be  subject  to  approval  by  the  stockholders  of  the  Company 
within twelve (12) months after the date the Plan is adopted.  Such stockholder approval will be obtained in 
the manner and to the degree required under Applicable Laws.

sole discretion, may permit all participants in a specified Offering to contribute amounts to the Plan 
through payment by cash, check or other means set forth in the subscription agreement prior to each 
Exercise  Date  of  each  Offering  Period,  provided  that  payment  through  means  other  than  payroll 
deductions  shall  be  permitted  only  if  the  participant  has  not  already  had  the  maximum  permitted 
amount  withheld  through  payroll  deductions  during  the  Offering  Period.    A  participant’s 
subscription  agreement  shall  remain  in  effect  for  successive  Offering  Periods  unless  terminated  as 
provided in Section 10 hereof. 

(b) Payroll deductions authorized by a participant will commence on the first payday 
following the Enrollment Date and will end on the last payday in the Offering Period to which such 
authorization is applicable, unless sooner terminated by the participant as provided in Section 10. 

(c)  All  Contributions  made  for  a  participant  will  be  credited  to  his  or  her  account 
under  the  Plan  and  will  be  made  in  whole  percentages  only.    A  participant  may  not  make  any 
additional payments into such account. 

(d) A participant may discontinue his or her participation in the Plan as provided in 
Section  10,  or  may  increase  or  decrease  the  rate  of  his  or  her  Contributions  during  the  Offering 
Period by (i) properly completing and submitting to the Company’s payroll office (or its designee), 
on  or  before  a  date  prescribed  by  the  Administrator  prior  to  an  applicable  Exercise  Date,  a  new 
subscription  agreement  authorizing  the  change  in  Contribution  rate  in  the  form  provided  by  the 
Administrator for such purpose, or (ii) following an electronic or other procedure prescribed by the 
Administrator;  provided,  however,  that  unless  the  Administrator  provides  otherwise,  a  participant 
may  reduce,  but  not  increase,  his  or  her  Contribution  rate  during  an  Offering  Period  for  that  
Offering Period (it being understood that a participant may increase the Contribution rate for future 
Offering Periods prior to the commencement of any such Offering Period).  If a participant has not 
followed  such  procedures  to  change  the  rate  of  Contributions,  the  rate  of  his  or  her  Contributions 
will  continue  at  the  originally  elected  rate  throughout  the  Offering  Period  and  future  Offering 
Periods (unless terminated as provided in Section 10).  The Administrator may, in its sole discretion, 
limit the nature and/or number of Contribution rate changes that may be made by participants during 
any Offering Period.  Any change in payroll deduction rate made pursuant to this Section 6(d) will 
be effective as of the first full payroll period following five (5) business days after the date on which 
the  change  is  made  by  the  participant  (unless  the  Administrator,  in  its  sole  discretion,  elects  to 
process a given change in payroll deduction rate more quickly).   

(e)  Notwithstanding  the  foregoing,  to  the  extent  necessary  to  comply  with 
Section 423(b)(8) of the Code and Section 3(b), a participant’s Contributions  may be decreased to 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-92- 

 
 
 
 
 
 
 
 
zero percent (0%) at any time during an Offering Period.  Subject to Section 423(b)(8) of the Code 
and  Section  3(b)  hereof,  Contributions  will  recommence  at  the  rate  originally  elected  by  the 
participant effective as of the beginning of the first Offering Period which is scheduled to end in the 
following calendar year, unless terminated by the participant as provided in Section 10. 

(f)  Notwithstanding any provisions to the contrary in the Plan, the Administrator may 
allow Employees to participate in the Plan via cash contributions instead of payroll deductions if (i) 
payroll  deductions  are  not  permitted  under  applicable  local  law,  and  (ii)  the  Administrator 
determines that cash contributions are permissible under Section 423 of the Code. 

(g) At the time the option is exercised, in whole or in part, or at the time some or all 
of the Company’s Common Stock issued under the Plan is disposed of, the participant must make 
adequate  provision  for  the  Company’s  federal,  state,  or  other  tax  withholding  obligations,  if  any, 
which arise upon the exercise of the option or the disposition of the Common Stock.  At any time, 
the  Company  may,  but  will  not  be  obligated  to,  withhold  from  the  participant’s  compensation  the 
amount  necessary  for  the  Company  to  meet  applicable  withholding  obligations,  including  any 
withholding required to make available to the Company any tax deductions or benefits attributable to 
the sale or early disposition of Common Stock by the Employee.  In addition, the Company or the 
Employer,  may,  but  will  not  be  obligated  to,  withhold  from  the  proceeds  of  the  sale  of  Common 
Stock or any other method of withholding the Company or the Employer deems appropriate to the 
extent permitted by U.S. Treasury Regulation Section 1.423-2(f).  

7.  Grant  of  Option.    On  the  Enrollment  Date  of  each  Offering  Period,  each  Employee 
participating in such Offering Period will be granted an option to purchase on the Exercise Date(s) of 
such Offering Period (at the applicable Purchase Price) up to a number of shares of Common Stock 
determined  by  dividing  such  participant’s  Contributions  accumulated  prior  to  such  Exercise  Date 
and  retained in  the participant’s account as  of  the Exercise Date by the applicable Purchase Price; 
provided  that  in  no  event  will  a  participant  be  permitted  to  purchase  during  each  Offering  Period 
more  than  five  thousand  (5,000)  shares  of  Common  Stock  (subject  to  any  adjustment  pursuant  to 
Section  19),  and  provided  further  that  such  purchase  will  be  subject  to  the  limitations  set  forth  in 
Sections  3(b)  and  13.    The  Employee  may  accept  the  grant  of  such  option  with  respect  to  any 
Offering  Period  under  the  Plan,  by  electing  to  participate  in  the  Plan  in  accordance  with  the 
requirements of Section 5.  The Administrator may, for future Offering Periods, increase or decrease, 
in its absolute discretion, the maximum number of shares of Common Stock that a participant may 
purchase during each Offering Period.  Exercise of the option will occur as provided in Section 8, 
unless the participant has withdrawn pursuant to Section 10.  The option will expire on the last day 
of the Offering Period.  

8.  Exercise of Option.   

(a)  Unless a participant withdraws from the Plan as provided in Section 10, his or her 
option for the purchase of shares of Common Stock will be exercised automatically on the Exercise 
Date,  and  the  maximum  number  of  full  shares  subject  to  the  option  will  be  purchased  for  such 
participant at the applicable Purchase Price with the accumulated Contributions in his or her account.  
No  fractional  shares  of  Common  Stock  will  be  purchased;  any  Contributions  accumulated  in  a 
participant’s  account  which  are  not  sufficient  to  purchase  a  full  share  will  be  returned  to  the 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-93- 

 
 
 
 
 
 
 
participant.    Any  other  funds  left  over  in  a  participant’s  account  after  the  Exercise  Date  will  be 
returned to the participant.  During a participant’s lifetime, a participant’s option to purchase shares 
hereunder is exercisable only by him or her. 

(b) Notwithstanding  any  contrary  Plan  provision,  if  the  Administrator  determines 
that, on a given Exercise Date, the number of shares of Common Stock with respect to which options 
are to be exercised may exceed (i) the number of shares of Common Stock that were available for 
sale under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of 
shares of Common Stock available for sale under the Plan on such Exercise Date, the Administrator 
may in its sole discretion (x) provide that the Company will make a pro rata allocation of the shares 
of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, 
in  as  uniform  a  manner  as  will  be  practicable  and  as  it  will  determine  in  its  sole  discretion  to  be 
equitable  among  all  participants  exercising  options  to  purchase  Common  Stock  on  such  Exercise 
Date, and either (x) continue any Offering Period then in effect, or (y) terminate any Offering Period 
then in effect pursuant to Section 20.  The Company may make pro rata allocation of the shares of 
Common Stock available on the Enrollment Date of any applicable Offering Period pursuant to the 
preceding  sentence,  notwithstanding  any  authorization  of  additional  shares  of  Common  Stock  for 
issuance under the Plan by the Company’s stockholders subsequent to such Enrollment Date. 

9.  Delivery.    As  soon  as  administratively  practicable  after  each  Exercise  Date  on  which  a 
purchase  of  shares  of  Common  Stock  occurs,  the  Company  will  arrange  the  delivery  to  each 
participant,  as  appropriate,  the  shares  purchased  upon  exercise  of  his  or  her  option  in  a  form 
determined  by  the  Administrator  (in  its  sole  discretion)  and  pursuant  to  rules  established  by  the 
Administrator.    No  participant  will  have  any  voting,  dividend,  or  other  stockholder  rights  with 
respect to shares of Common Stock subject to any option granted under the Plan until such shares 
have been purchased and delivered to the participant as provided in this Section 9. 

10. Withdrawal. 

(a)  Under  procedures  established  by  the  Administrator,  a  participant  may  withdraw 
all but not less than all the Contributions credited to his or her account and not yet used to exercise 
his or her option under the Plan at any time by (i) submitting to the Company’s payroll office (or its 
designee)  a  written  notice  of  withdrawal  in  the  form  prescribed  by  the  Administrator  for  such 
purpose,  or  (ii)  following  an  electronic  or  other  withdrawal  procedure  prescribed  by  the 
Administrator.  All  of  the  participant’s  Contributions  credited  to  his  or  her  account  will  be  paid  to 
such participant as promptly as practicable after the effective date of his or her withdrawal and such 
participant’s  option  for  the  Offering  Period  will  be  automatically  terminated,  and  no  further 
Contributions  for  the  purchase  of  shares  will  be  made  for  such  Offering  Period.    If  a  participant 
withdraws  from  an  Offering  Period,  Contributions  will  not  resume  at  the  beginning  of  the 
succeeding  Offering  Period  unless  the  participant  re-enrolls  in  the  Plan  in  accordance  with  the 
provisions of Section 5. 

(b) A participant’s withdrawal from an Offering Period will not have any effect upon 
his  or  her  eligibility  to  participate  in  any  similar  plan  which  may  hereafter  be  adopted  by  the 
Company or in succeeding Offering Periods which commence after the termination of the Offering 
Period from which the participant withdraws. 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-94- 

 
 
 
 
 
 
 
11. Termination  of  Employment.  Upon  a  participant’s  ceasing  to  be  an  Employee,  for  any 
reason, he or she will be deemed to have elected to withdraw from the Plan and the Contributions 
credited to such participant’s account during the Offering Period but not yet used to purchase shares 
of  Common  Stock  under  the  Plan  will  be  returned  to such  participant  or,  in  the  case  of  his  or  her 
death, to the person or persons entitled thereto under Section 15, and such participant’s option will 
be  automatically  terminated.    The  preceding  sentence  notwithstanding,  a  participant  who  receives 
payment  in  lieu  of  notice  of  termination  of  employment  will  be  treated  as  continuing  to  be  an 
Employee  for  the  participant’s  customary  number  of  hours  per  week  of  employment  during  the 
period in which the participant is subject to such payment in lieu of notice.   

12. Interest.  No interest will accrue on the Contributions of a participant in the Plan, except 
as may be required by applicable law, as determined by the Company, and if so required by the laws 
of a particular jurisdiction, shall apply to all participants in the relevant Offering except to the extent 
otherwise permitted by U.S. Treasury Regulation Section 1.423-2(f). 

13. Stock. 

(a)  Subject to adjustment upon changes in capitalization of the Company as provided 
in Section 19, the maximum number of shares of Common Stock which will be made available for 
sale under the Plan will be 3,100,000 shares of Common Stock.   

(b) Shares of Common Stock to be delivered to a participant under the Plan will be 

registered in the name of the participant or in the name of the participant and his or her spouse. 

14. Administration.    The  Board  or  a  committee  of  members  of  the  Board  who  will  be 
appointed from time to time by, and will serve at the pleasure of, the Board, will administer the Plan.  
The  Administrator  will  have  full  and  exclusive  discretionary  authority  to  construe,  interpret  and 
apply the terms of the Plan, to designate separate Offerings under the Plan, to determine eligibility, 
to adjudicate all disputed claims filed under the Plan and to establish such procedures that it deems 
necessary for administration of the Plan (including, without limitation, to adopt such procedures and 
sub-plans as are necessary or appropriate to permit the participation in the Plan by employees who 
are foreign nationals or employed outside the United States).  Unless otherwise determined by the 
Administrator,  the  Employees  eligible  to  participate  in  each  such  sub-plan  will  participate  in  a 
separate Offering.  The Administrator, in its sole discretion and on such terms and conditions as it 
may  provide,  may  delegate  to  one  or  more  individuals  all  or  any  part  of  its  authority  and  powers 
under  the  Plan.    Every  finding,  decision  and  determination  made  by  the  Administrator  (or  its 
designee) will, to the full extent permitted by law, be final and binding upon all parties. 

15. Designation of Beneficiary. 

(a)  A  participant  may  designate  a  beneficiary  who  is  to  receive  any  shares  of 
Common Stock and cash, if any, from the participant’s account under the Plan in the event of such 
participant’s  death  subsequent  to  an  Exercise  Date  on  which  the  option  is  exercised  but  prior  to 
delivery  to  such  participant  of  such  shares  and  cash.    In  addition,  a  participant  may  designate  a 
beneficiary who is to receive any cash from the participant’s account under the Plan in the event of 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-95- 

 
 
 
 
 
 
 
 
 
 
such participant’s death prior to exercise of the option.  If a participant is married and the designated 
beneficiary is not the spouse, spousal consent will be required for such designation to be effective. 

(b) The participant may change such designation of beneficiary at any time by written 
notice.    In  the  event  of  the  death  of  a  participant  and  in  the  absence  of  a  beneficiary  validly 
designated  under  the  Plan  who  is  living  at  the  time  of  such  participant’s  death,  the  Company  will 
deliver such shares and/or cash to the executor or administrator of the estate of the participant, or if 
no  such  executor  or  administrator  has  been  appointed  (to  the  knowledge  of  the  Company),  the 
Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more 
dependents  or  relatives  of  the  participant,  or  if  no  spouse,  dependent  or  relative  is  known  to  the 
Company, then to such other person as the Company may designate. 

(c)  All beneficiary designations under this Section 15 will be made in such form and 
manner as the Administrator may prescribe from time to time.  Notwithstanding Sections 15(a) and 
(b)  above,  the  Company  and/or  the  Administrator  may  decide  not  to  permit  such  designations  by 
participants  in  non-U.S.  jurisdictions  to  the  extent  permitted  by  U.S.  Treasury  Regulation  Section 
1.423-2(f). 

16. Transferability.  Neither Contributions credited to a participant’s account nor any rights 
with regard to the exercise of an option or to receive shares of Common Stock under the Plan may be 
assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of 
descent  and  distribution  or  as  provided  in  Section  15)  by  the  participant.    Any  such  attempt  at 
assignment,  transfer,  pledge  or  other  disposition  will  be  without  effect,  except  that  the  Company 
may treat such act as an election to withdraw from an Offering Period in accordance with Section 10. 

17. Use of Funds.  The Company may use all Contributions received or held by the Company 
under the Plan for any corporate purpose, and the Company will not be obligated to segregate such 
Contributions,  except  under  Offerings  in  which  applicable  local  law  requires  that  Contributions  to 
the Plan by participants be segregated from the Company’s general corporate funds and/or deposited 
with an independent third party for participants in non-U.S. jurisdictions.  Until shares of Common 
Stock are issued under the Plan (as evidenced by the appropriate entry on the books of the Company 
or of a duly authorized transfer agent of the Company), a participant will only have the rights of an 
unsecured creditor with respect to such shares. 

18. Reports.    Individual  accounts  will  be  maintained  for  each  participant  in  the  Plan.  
Statements of account will be given to participating Employees at least annually, which statements 
will  set  forth  the  amounts  of  Contributions,  the  Purchase  Price,  the  number  of  shares  of  Common 
Stock purchased and the remaining cash balance, if any. 

19. Adjustments, Dissolution, Liquidation or Change of Control. 

(a)  Adjustments.  In the event that any dividend or other distribution (whether in the 
form  of  cash,  Common  Stock,  other  securities,  or  other  property),  recapitalization,  stock  split, 
reverse  stock  split,  reorganization,  merger,  consolidation,  split-up,  spin-off,  combination, 
repurchase, or exchange of Common Stock or other securities of the Company, or other change in 
the  corporate  structure  of  the  Company  affecting  the  Common  Stock  such  that  an  adjustment  is 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-96- 

 
 
 
 
 
 
 
 
 
appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended 
to be made available under the Plan, the Administrator will adjust the number and class of Common 
Stock which may be delivered under the Plan, the Purchase Price per share and the number of shares 
of Common Stock covered by each option under the Plan which has not yet been exercised, and the 
numerical limits of Sections 7 and 13.   

(b) Dissolution or Liquidation.  In the event of the proposed dissolution or liquidation 
of the Company, any Offering Period then in progress will be shortened by setting a new Exercise 
Date (the “New Exercise Date”), and will terminate immediately prior to the consummation of such 
proposed  dissolution  or  liquidation,  unless  provided  otherwise  by  the  Board.    The  New  Exercise 
Date will be before the date of the Company’s proposed dissolution or liquidation.  The Board will 
notify each participant in writing or electronically, at least ten (10) business days prior to the New 
Exercise  Date,  that  the  Exercise  Date  for  the  participant’s  option  has  been  changed  to  the  New 
Exercise Date and that the participant’s option will be exercised automatically on the New Exercise 
Date, unless prior to such date the participant has withdrawn from the Offering Period as provided in 
Section 10.   

(c)  Change of Control.  In the event of a Change of Control, each outstanding option 
will  be  assumed  or  an  equivalent  option  substituted  by  the  successor  corporation  or  a  Parent  or 
Subsidiary  of  the  successor  corporation.    In  the  event  that  the  successor  corporation  refuses  to 
assume or substitute for the option, any Offering Period then in progress will be shortened by setting 
a new Exercise Date (the “New Exercise Date”) and any Offering Period then in progress will end 
on  the  New  Exercise  Date.    The  New  Exercise  Date  will  be  before  the  date  of  the  Company’s 
proposed Change of Control.  The Board will notify each participant in writing or electronically, at 
least  ten  (10)  business  days  prior  to  the  New  Exercise  Date,  that  the  Exercise  Date  for  the 
participant’s option has been changed to the New Exercise Date and that the participant’s option will 
be exercised automatically on the New Exercise Date, unless prior to such date the participant has 
withdrawn from the Offering Period as provided in Section 10. 

20. Amendment or Termination. 

(a)  The  Administrator  may  at  any  time  and  for  any  reason  terminate  or  amend  the 
Plan.  Except as provided in Section 19, no such termination can affect options previously granted 
under  the  Plan,  provided  that  an  Offering  Period  may  be  terminated  by  the  Administrator  on  any 
Exercise Date if the Administrator determines that the termination or suspension of the Plan is in the 
best  interests  of  the  Company  and  its  stockholders.    Except  as  provided  in  Section  19  and  this 
Section 20, no amendment may make any change in any option theretofore granted which adversely 
affects the rights of any participant.  To the extent necessary to comply with Section 423 of the Code 
(or any successor rule or provision or any other applicable law, regulation or stock exchange rule), 
the Company will obtain stockholder approval in such a manner and to such a degree as required. 

(b) Without stockholder consent and without regard to whether any participant rights 
may be considered to have been “adversely affected,” the Administrator will be entitled to change 
the Offering Periods, designate separate Offerings, limit the frequency and/or number of changes in 
the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts 
withheld  in  a  currency  other  than  U.S.  dollars,  permit  Contributions  in  excess  of  the  amount 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-97- 

 
 
 
 
 
 
 
designated by a participant in order to adjust for delays or mistakes in the Company’s processing of 
properly  completed  withholding  elections,  establish  reasonable  waiting  and  adjustment  periods 
and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of 
Common  Stock  for  each  participant  properly  correspond  with  Contribution  amounts,  and  establish 
such other limitations or procedures as the Administrator determines in its sole discretion advisable 
which are consistent with the Plan. 

(c)  In the event the Administrator determines that the ongoing operation of the Plan 
may result in unfavorable financial accounting consequences, the Board may, in its discretion and, to 
the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such 
accounting consequence including, but not limited to: 

amending  the  Plan  to  conform  with  the  safe  harbor  definition  under 
Statement  of  Financial  Accounting  Standards  Codification  Topic  718  (or  any  successor  thereto), 
including with respect to an Offering Period underway at the time; 

(i) 

Offering Period underway at the time of the change in Purchase Price; 

(ii) 

altering  the  Purchase  Price  for  any  Offering  Period  including  an 

new Exercise Date, including an Offering Period underway at the time of the Board action; 

(iii) 

shortening any Offering Period so that such Offering Period ends on a 

elect to set aside as Contributions; and 

(iv) 

reducing the maximum percentage of Compensation a participant may 

during any Offering Period. 

(v) 

reducing  the  maximum  number  of  Shares  a  participant  may  purchase 

Such modifications or amendments will not require stockholder approval or the consent of any Plan 
participants. 

21. Notices.  All notices or other communications by a participant to the Company under or 
in connection with the Plan will be deemed to have been duly given when received in the form and 
manner specified by the Company at the location, or by the person, designated by the Company for 
the receipt thereof. 

22. Conditions Upon Issuance of Shares.  Shares of Common Stock will not be issued with 
respect to an option under the Plan unless the exercise of such option and the issuance and delivery 
of  such  shares  pursuant  thereto  will  comply  with  all  applicable  provisions  of  law,  domestic  or 
foreign,  including,  without  limitation,  the  Securities  Act  of  1933,  as  amended,  including  the  rules 
and  regulations  promulgated  thereunder,  the  Exchange  Act,  and  the  requirements  of  any  stock 
exchange upon which  the shares may then  be  listed, and will  be further subject to the approval of 
counsel for the Company with respect to such compliance. 

As a condition to the exercise of an option, the Company may require the person exercising 
such  option  to  represent  and  warrant  at  the  time  of  any  such  exercise  that  the  shares  are  being 
purchased only for investment and without any present intention to sell or distribute such shares if, 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-98- 

 
 
 
 
 
 
 
 
 
in  the  opinion  of  counsel  for  the  Company,  such  a  representation  is  required  by  any  of  the 
aforementioned applicable provisions of law. 

23. Term of Plan.  The Plan will become effective upon the earlier to occur of its adoption by 
the Board or its approval by the stockholders of the Company.  It will continue in effect for a term of 
ten (10) years, unless sooner terminated under Section 20.

____________________  hereby  elects  to  participate  in  the  Rambus  Inc.  2006  Employee 
Stock  Purchase  Plan  (the  “Plan”)  and  subscribes  to  purchase  shares  of  the  Company’s 
Common Stock in accordance with this Subscription Agreement and the Plan. 

I  hereby  authorize  payroll  deductions  from  each  paycheck  in  the  amount  of  ____%  of  my 
Compensation  on  each  payday  (from  1  to  15%)  during  the  Offering  Period  in  accordance 
with the Plan.  (Please note that no fractional percentages are permitted.) 

I understand that said payroll deductions will be accumulated for the purchase of shares of 
Common Stock at the applicable Purchase Price determined in accordance with the Plan.  I 
understand  that  if  I  do  not  withdraw  from  an  Offering  Period,  any  accumulated  payroll 
deductions will be used to automatically exercise my option. 

I have received a copy of the complete Plan.  I understand that my participation in the Plan is 
in all respects subject to the terms of the Plan.  I understand that my ability to exercise the 
option under this Subscription Agreement is subject to stockholder approval of the Plan. 

Shares of Common Stock purchased for me under the Plan should be issued in the name(s) of 
Employee or Employee and Spouse only. 

I understand that if I dispose of any shares received by me pursuant to the Plan within 2 years 
after the Enrollment Date (the first day of the Offering Period during which I purchased such 
shares) or one year after the Exercise Date, I will be treated for federal income tax purposes 
as having received ordinary income at the time of such disposition in an amount equal to the 
excess of the fair market value of the shares at the time such shares were purchased by me 
over the price which I paid for the shares.  I hereby agree to notify the Company in writing 
within  30  days  after  the  date  of  any  disposition  of  my  shares  and  I  will  make  adequate 
provision for Federal, state or other tax withholding obligations, if any, which arise upon the 
disposition of the Common Stock.  The Company may, but will not be obligated to, withhold 
from my compensation the amount necessary to meet any applicable withholding obligation 
including any withholding necessary to make available to the Company any tax deductions or 
benefits attributable to sale or early disposition of Common Stock by me.  If I dispose of such 

2011 10-K & Proxy Combo bannerless FINAL.docx 

-100- 

 
 
 
shares at any time after the expiration of the 2-year and 1-year holding periods, I understand 
that I will be treated for federal income tax purposes as having received income only at the 
time of such disposition, and that such income will be taxed as ordinary income only to the 
extent of an amount equal to the lesser of (1) the excess of the fair market value of the shares 
at the time of such disposition over the purchase price which I paid for the shares, or (2) 15% 
of the fair market value of the shares on the first day of the Offering Period.  The remainder 
of the gain, if any, recognized on such disposition will be taxed as capital gain.
