Fellow Shareholders, 

 2016  was  a  solid  year  for  Cray,  highlighted  by  continued  momentum  in  our  high-end  business  and 
completion  of  several  of  the  largest,  most  complex  supercomputing  and  storage  systems  we  have  ever  built.    We 
refreshed our product line-up and delivered the second-highest annual revenue total in our history, as well as another 
year  of  profitability.    We  delivered  all  of  this  despite  our  primary  market  experiencing  a  slowdown,  which  is 
continuing today but which we believe will be temporary in nature as long-term growth prospects appear strong.  As 
you are likely aware, due to the nature of our high-end business, our revenue tends to be lumpy on a quarterly basis, 
and at times even on an annual basis.  However, if you step back and take a longer view, we have clearly been on a 
strong revenue growth path over the past several years.  In fact, our revenue has grown at more than 10% per year 
on a compounded basis since 2009 – largely driven by the strength of our solutions serving a growing set of users 
and markets.   

We  remain  focused  on  three  key  markets:  supercomputing,  storage  and  analytics,  each  spanning  our 
traditional  government  and  academic  customer  base  as  well  as  commercial  markets  including  energy, 
manufacturing, financial services and healthcare/life sciences.  As digital data continues to expand at ever-increasing 
rates, the need for high-performance solutions to compute, store and analyze this data also increases.  Our position at 
the high-end of each of these markets gives us unique perspective and focus.  We are delivering solutions that enable 
our customers to gain new insights into their information, leveraging large scale modeling and simulation combined 
with data analytics and artificial intelligence, as these computing methods continue to converge over time.  Several 
trends are driving this convergence, including the sheer growth of data and the desire to streamline and enhance the 
analysis  process,  as  well  as  the  potential  for  significant  performance  improvement  through  converged  offerings 
which will ultimately help customers make better decisions faster.   

We  take  great  pride  that  Cray  systems  are  being  used  to  improve  life  on  our  planet  every  day.    Some 
examples of this work are highlighted in the images on the front of this annual report, including Dr. William Loging 
of Mt. Sinai Hospital, who is improving drug discovery success rates; University of Illinois at Urbana-Champaign 
researchers Wendy K. Tam Cho and Yan Liu, who are analyzing the fairness of electoral district boundaries; Sverre 
Brandsberg-Dahl  and  PGS,  who  are  generating  high-resolution  three-dimensional  seismic  images  that  more 
accurately  locate  oil  and  gas  resources;  Helen  Roberts  and  the  U.K.  Met  Office,  who  are  safeguarding  lives  and 
livelihoods with advanced weather forecasts; and Dr. Laura Boykin of the University of Western Australia and Dr. 
Titus  Alicai  of  Uganda’s  NaCRRI,  who  are  fighting  famine  in  East  Africa.    We’re  proud  to  partner  with  these 
amazing people in their lifechanging work. 

For  the  supercomputing  market,  we  have  two  primary  offerings:  our  XC-line  of  supercomputers  and  our 
CS-line  of  highly  flexible  clusters.    Our  XC-line  is  the  most  powerful,  highest-performance  system  we  have  ever 
built,  able  to  scale  real-world  scientific,  engineering  and  data  intensive  applications  to  the  highest  levels  in  the 
industry.  The XC system harnesses the Cray Aries high-performance system interconnect as well as the latest Intel 
Xeon processors, Intel Xeon Phi coprocessors and Nvidia Tesla GPU accelerators, along with a tightly-integrated, 
highly  productive  software  stack.    Our  CS-line  of  clusters  delivers  industry  standards-based,  highly  customizable 
systems expressly designed to handle the broadest range of medium- to large-scale workloads.  We bring all of this 
together in our Adaptive Supercomputing vision, which enables the configuration of different processors in a single, 
hybrid supercomputer, ensuring users have the best system for a wide variety of workloads and applications.  

We installed numerous Cray systems around the world during 2016, including several that now rank among 
the fastest in the world.  Among these were new petascale XC supercomputers at several U.S. Department of Energy 
laboratories,  including  Argonne  National  Laboratory,  Lawrence  Berkley  National  Laboratory,  and  a  joint  project 
between Los Alamos National Laboratory and Sandia National Laboratory.   

We also have two unique storage offerings; the Sonexion scale-out Lustre storage system, and Data Warp, 
a  layer  of  non-volatile  solid-state  storage  that  sits  between  the  compute  memory  and  parallel  file  system  to 
dramatically  improve  application  performance.    Together  these  solutions  drive  improved  performance,  scalability 
and  total  cost  of  ownership,  as  well  as  provide  a  clear  path  to  future  generations  of  new  storage  and  memory 
technologies. 

 
 
  We launched an entirely new analytics solution in 2016, the Urika-GX big data platform.  The Urika-GX 
fuses  some  of  our  most  unique  supercomputing  technology  with  an  open,  standards-based  software  framework  to 
deliver  the  industry’s  first  agile  analytics  platform.    Market  reaction  to  the  Urika-GX  has  been  positive  and  we 
installed  new  Urika  solutions  at  several  government  institutions  and  national  laboratories,  as  well  as  commercial 
customers  in  life  sciences,  marketing  and  customer  engagement,  and  a  European  automotive  consortium.    It  is 
exciting to see customers leveraging our supercomputing systems and technology in new ways as we expand into 
this big and fast moving new market. 

We  remain  focused  on  three  primary  strategic  goals  as  a company:  first,  to  grow revenue faster  than  the 
markets  in  which  we  compete;  second,  to  grow  the  percentage  of  our  revenue  that  comes  from  the  commercial 
markets to more than one-third of our total revenue; and third, to expand our presence in the big data market to drive 
more than one-third of our revenue over time.  We aim to achieve these goals while also expanding our profitability 
over time.  While the slowdown in our target market is impacting our visibility for 2017, we expect it to rebound 
over  time  as  the  market’s  long-term  growth  drivers  appear  firmly  intact.    As  such,  we  are  continuing  to  make 
investments in our products and services to expand our strong competitive position and our long-term opportunity to 
drive growth.   

Among these are targeted investments in big data analytics and artificial intelligence, and especially in deep 
learning, which can benefit greatly from supercomputing technology.  Deep learning has demonstrated tremendous 
utility  in  creating  predictive  computer  models  from  ever-growing  volumes  of  data,  and  is  being  rapidly  deployed 
across many industries and markets.  As data volumes and model complexity continue to grow, the deep learning 
training problem requires increasingly powerful computing systems, scaling to large node counts with very strong 
system  interconnects  and  fast  storage  systems.    Our  CS  and  XC  supercomputers  are  ideally  suited  for  these 
workloads.   

An example of this is a partnership we have with Microsoft and the Swiss National Supercomputing Center 
to  scale  Microsoft’s  Cognitive  Toolkit  to  an  unprecedented  2,000  Nvidia  Pascal  P100  GPUs  on  a  Cray  XC50 
system.  This is a great proof point of how deep learning is part of the growing convergence of data analytics and 
supercomputing, a focus of ours over the past several years.  We have also increased our investments to enable our 
systems  to  be  leveraged  in  cloud  computing  environments.    An  exciting  example  of  this  is  our  partnership  with 
Deloitte’s  Advisory  Cyber  Risk  Services,  which  we  launched  in  2016  to  deliver  the  first  commercially  available 
high-speed threat analytics service, powered by a Cray supercomputer.  

Finally, we recently added a new leader to our team, Stathis Papaefstathiou, who joined us as our senior 
vice president of R&D, replacing Peg Williams who is retiring.  With more than 30 years of high-tech experience, 
Stathis brings a diverse technical background including network hardware, high performance computing, embedded 
operating  systems,  cloud-enabled  network  management  solutions,  and  big  data  analytics.    We  are  pleased  to 
welcome him and all our new employees to the Cray team and wish Peg the best in retirement after many years of 
strong contributions not only to Cray but the entire HPC industry. 

On  behalf  of  our  board  of  directors  and  management,  I  would  like  to  thank  all  our  customers,  partners, 

employees and shareholders for your continued confidence and support of Cray. 

Sincerely, 

Peter J. Ungaro 
President and Chief Executive Officer

Products, Services and Customer Support 

We concentrate on building product solutions for our customers in two major markets: the supercomputing portion of HPC;  
and big data, including data analytics and storage. We also provide a range of service offerings around these products that leverage 
our high quality support and intimate understanding of our customers and their requirements. 

Cray Supercomputing Systems 

Our supercomputing products span a broad performance spectrum and address the critical computing resource challenges HPC 
users face today: achieving massive scaling to tens of thousands of processors; ease of use for high productivity; and very high
levels of sustained performance on real applications. We achieve this by designing and integrating supercomputers that combine 
highly capable processors, high speed interconnect technology for maximum communication efficiency and innovative packaging to 
address increased density, processor power requirements, upgradability, energy efficiency and reliability requirements.  In addition, 
we include scalable system software that significantly enhances performance, productivity and manageability at supercomputing 
scale. With our “Adaptive Supercomputing” vision, we have expanded the concept of heterogeneous computing to a fully integrated
view of hardware and software supporting both multiple processing technologies and diverse workloads. 

Our supercomputers are the result of our Adaptive Supercomputing vision that integrates diverse technologies into a unified 
architecture enabling customers to match the computational solution to the need. Our systems utilize components and technologies
designed to support the requirements of the most demanding HPC users. Our XC series supercomputers, comprising the XC40 and 
XC50, are designed to provide significantly higher sustained performance on many important applications that require the highest
levels of scaling, with substantial performance improvements over competing solutions. Our CS series of supercomputer cluster 
solutions (including CS400 and CS-Storm) emphasize flexibility, capacity and custom design and integration for compute-intensive
customer needs. All of our supercomputers are designed to enable HPC users to focus on their primary objectives, including 
advancing scientific discovery, increasing industrial capabilities, providing predictive analyses and improving national security. 

Our supercomputer systems are designed to offer a variety of additional benefits, including: 

•

superior price-performance compared to other supercomputer systems as well as compared to enterprise computing 
solutions and cloud computing solutions;

that integrate with computing solutions ranging from third-party clusters and Cray cluster supercomputers to highly integrated 
supercomputers. 

Cray Sonexion Storage Systems. Our flagship storage product line, the Cray Sonexion, embeds the Lustre parallel file system 
and other software in an optimal configuration to reduce deployment time while increasing reliability, capacity and performance.
Cray  Sonexion  offers  an  optimal  combination  of  modular  scaling  capacity  from  terabytes  to  petabytes  and  sustained  I/O 
performance from several gigabytes per second to over one terabyte per second in a single file system. High density is achieved
through reducing storage componentry and cabling. Sonexion systems are engineered to be installed and put into production more 
quickly than other HPC storage solutions and can be attached to Cray XC and Cray CS series systems, as well as industry-standard
Linux clusters.

Cray DataWarp Applications Accelerator. Our DataWarp technology addresses a key problem experienced by supercomputing 
customers:  Disk based storage input/output, or I/O, has not kept up with Moore’s Law and delivering sustainable performance on a 
spectrum of applications with varying I/O-intensive workloads has become costly and impractical. DataWarp provides a new tier of
storage featuring SSD and in-memory flash that is tightly integrated with Cray XC series supercomputing resources. DataWarp 
supports  high  application  I/O  requirements  while  reducing  overall  application  computing  time  for  I/O-intensive  workloads. 
Production customers have seen almost two terabytes per second of I/O capacity with DataWarp while having the ability to make 
scientific discoveries faster.

Engineering and Customer Support 

Custom Engineering.  To address those users whose needs cannot be met through our standard product offerings, we provide 
an alternative. Our custom engineering business leverages our amassed intellectual property and technology portfolio, deep domain 
expertise and know-how to design and build solutions and services designed to match a customer’s specific needs. The need for a
unique solution often stems from special processing needs that are often performance, application or capacity related; special 

3

environmental needs that might include special size dimension, weight, power and cooling limitations; or unique interface or system 
software and integration requirements.

Customer Support.  Our worldwide customer support organization delivers to our customers the “Cray experience” that 
provides us with a competitive advantage. We believe that the quality of our customer support personnel plays an important role in 
our ability to maintain long-term customer relationships. Support services are important to our customers, and in many cases we
locate our support personnel at or near customer sites globally, supported by a central service organization. Our support services 
include hardware and software maintenance in support of our systems, applications support, installation project management, system 
installation and de-installation, site preparation and technical training for our systems. In addition, we offer ancillary services in 
application consulting, third-party software support, site engineering, on-site analysts for defined projects and specialized training. 
In 2016, maintenance and support revenue accounted for roughly $108 million of our total revenue. Our support arrangements 
generally provide for support services on an annual basis, although several cover multiple years. While most customers pay for 
support on an annual basis, others pay on a monthly, quarterly or multi-year basis. Typically, customers may select levels of support 
and response times, ranging from delivery of parts only, to 24 x 7 coverage with two-hour response times.

Sales and Marketing 

We focus our sales and marketing activities on both horizontal and vertical marketing activities ranging from government 
agencies or funded research laboratories, to academic institutions and commercial entities requiring HPC, big data systems and 
storage. Our primary sales model is direct, and we offer solutions through a highly-trained direct sales force that operates throughout 
North America, South America, Asia, Europe, the Middle East, Australia and Africa. More than half of our sales force is located in 
the United States and Canada, with the remainder overseas. 

A formal request-for-proposal process for HPC systems or technology drives a majority of our highest-end systems sales and 
engineering service  engagements  in  the  academic  and  government  markets. We utilize  pre-sales  technical  experts  to  develop 
technical proposals that meet customer requirements and benchmarking teams to demonstrate the advantages of our particular 
supercomputing products or service being proposed. For a majority of our larger sales opportunities, the proposal process, including 
establishing system size, options, pricing and other commitments, involves a number of resources outside of our sales organization. 
While we often tailor our supercomputer (including cluster) solutions for individual customers, there is substantial commonality in 
the underlying components and systems, allowing us to leverage manufacturing and supply chain operations. 

Government agencies and government-funded scientific research institutions around the world comprise a large portion of our 
customer base. Our government programs’ efforts are an integral part of our overall strategy by actively managing our relationship 
with U.S. government agencies and Congress. 

Our marketing staff is primarily responsible for product marketing, marketing communications and segment marketing. 
Product marketing bridges our research and development organization and our sales staff to help ensure that our products meet the
demands and requirements of our key customers and a broader market set of prospects for our HPC and big data business and our 
new business initiatives. Marketing communications focus on our overall brand messaging, advertising, public relations, social 
media, conferences, trade shows and direct as well as online marketing campaigns to create brand awareness and generate demand.
Segment marketing focuses on providing products and services to specific customer sets, such as earth sciences, energy, financial
services, manufacturing and life sciences. 

Our Technology 

We are dependent on the successful early identification, development and timely introduction of new products and capabilities. 
Our research and development activities include identification of new trends, technologies and workload needs in the ever changing 
HPC and big data markets, and then leveraging this research in the design of system architectures, hardware and software necessary
to implement our expanding product portfolio to address customer needs. 

Product Architectures 

Our product portfolio covers a breadth of architectures including tightly integrated massively parallel supercomputers, highly 
flexible  and  configurable  cluster  supercomputers,  purpose-built  big  data  analytics  products  and  world  class  storage  and  data 
management solutions. 

Hardware 

We have extensive experience in the definition, design and integration of the hardware components required of HPC system 
solutions. This includes processors, board design, memory, storage, network and interconnect technologies, I/O subsystems, power, 

4

cooling and packaging infrastructures, along with the low-level hardware system software required to manage key components. The
majority of our hardware research and development investments are in the following areas: 

•

•

Compute and storage architectures, high-speed interconnect and board integration and design. Integration of a variety of 
processor, volatile and nonvolatile memory hierarchies and network devices using a combination of custom and industry 
standard printed circuit boards, high-density connectors, carefully chosen transmission and storage media and optimized 
topologies. 

Power, packaging and cooling. We use a variety of dense packaging techniques in order to produce systems with superior 
performance, socket densities and energy efficiency. This packaging combines industry standard and custom-designed 
technologies in the areas of printed circuit board assemblies, power distribution and liquid and air cooling. 

Software 

We have extensive experience in designing, developing and adapting system software such as the operating system, system 
management, optimized data management, movement and analysis, as well as programming environment software as an integral 
aspect of our product portfolio and distributing that software as part of system sales. Our software research and development 
experience includes operating system optimizations and scalable hardware control, monitoring and management, including power 
control, monitoring of environmental data, and hardware diagnostics.  Our integrated system software together provides Reliability, 
Availability and Serviceability, or RAS, for Cray systems. The Cray programming environment includes our own and commercially 
available third-party compilers, communication and scientific libraries as well as a rich suite of application development tools and 
software for achieving the best possible application performance. 

Additionally, we research innovative software for advanced analytics at scale, including industry leading graph analytics 
and associated algorithms for discovering previously unknown insights from large, disparate data sets, as well as optimizations to 
Hadoop  and  Spark  for  performance  and  manageability  at  scale.  Our  research  includes  techniques  and  optimizations  to  scale 
advanced analytics across distributed scalable systems, and in large, shared memory architectures. 

When necessary, we purchase or license certain software and technologies from third parties to meet certain specific customer 

requirements, while focusing our own resources where we believe we add the highest value. 

For information relating to amounts spent on research and development, see Note 18 - Research and Development in the Notes 
to Consolidated Financial Statements in Item 15. Exhibits and Financial Statement Schedules in Part IV of this annual report on
Form 10-K. 

Manufacturing and Supply Chain 

We subcontract the manufacture of a majority of the hardware sub-assemblies and certain components for our high-end 
products and custom-engineered systems, including integrated circuits, printed circuit boards, connectors, cables and power supplies, 
on a sole or limited source basis to third-party suppliers. We use contract manufacturers to assemble certain components. Our 
manufacturing strategy currently centers on build-to-order systems, focusing on obtaining competitive assembly and component 
costs while concentrating our resources on the final assembly, test and quality assurance stages to ensure a positive customer 
experience. This strategy allows us to avoid the large capital commitment and overhead associated with establishing full-scale 
manufacturing facilities, helps us to maintain the flexibility to adopt new technologies as they become available without the risk of 
equipment obsolescence, provides near real-time configuration changes to exploit faster and/or less expensive technologies and 
provides a higher level of large scale system quality. We perform final system integration, testing and quality checkout of our
systems. Our manufacturing personnel are located in Chippewa Falls, Wisconsin. We work closely with a supplier to provide 
integrated and tested Cray Sonexion storage products. 

Our systems designed for the supercomputer market segment and our custom-engineered solutions incorporate components 
that are available from single or limited sources, often containing our design input or proprietary designs. Such components include
integrated circuits, interconnect systems and certain memory devices. Prior to development of a particular product, components are 
typically competitively bid to a short list of technology partners. The technology partner that provides the highest value solution for 
the component is often awarded the contract for the life of the component. Once we have engaged a technology partner, changing 
our product designs to utilize another supplier’s integrated circuits or custom components can be a costly and time-consuming 
process. We also have sole or limited sources for less critical components, such as peripherals, power supplies, cooling and chassis 
hardware. We currently obtain key processors from Intel and NVIDIA for our Cray XC and cluster systems. We have a license for 
the Aries interconnect chip from Intel which we purchase through Broadcom Corporation (formerly Avago) that contracts with 
Taiwan Semiconductor Manufacturing Company for the manufacture of the integrated circuit. Our procurements from these vendors 
are primarily through purchase orders. We have chosen to deal with sole sources in specific cases due to the availability of specific 

5

technologies, economic advantages and other factors. Reliance on single or limited source vendors involves several risks, including 
the possibility of shortages of key components, long lead times, reduced control over delivery schedules, design or persistent quality 
issues  and  changes  in  direction  by  vendors.  We  have  been  adversely  affected  by  delays  in  obtaining  qualified  competitive 
components previously. 

Our Markets 

Our key target markets are (i) the supercomputing portion of the HPC market and (ii) the big data market, encompassing 
analytics, storage and artificial intelligence markets. High performance, real-time analytics on large volumes of data is developing 
into an important success driver for business, government and academia, and successfully leveraging this market is important to us. 
Big data is a relatively new target market for us, but several of our core strengths and technologies, such as the abilities to process 
vast amounts of unique data at very high speeds and to make “discoveries,” are demonstrated capabilities of our supercomputing 
solutions. Bringing these technologies to the big data market is core to Cray addressing big data challenges, enabling us to bring 
highly differentiated analytics offerings to market. The market segments we are targeting with our supercomputing, analytics and
storage products for HPC and big data are as follows: 

Scientific Research.    Scientific research includes government research laboratories and research universities around the 
world. In the U.S., the Department of Defense, through its High Performance Computing Modernization Program, funds a number 
of research organizations that are our target customers. The Office of Science in the Department of Energy and its laboratories are 
key customers, as are the National Science Foundation and the National Aeronautics and Space Administration and similar agencies
around the world. These research centers also provide supercomputing and big data resources to their affiliated organizations (such 
as the Department of Defense contractors) and industrial partners.

National Security.    Classified work in various worldwide government agencies has represented an important market for us 
over  many  years.  Certain  U.S.  government  departments  have  on  occasion  provided  funding  support  for  our  research  and 
development efforts to meet their objectives. Current and potential customers include a number of Department of Defense-related
classified  organizations,  the  National  Nuclear  Security  Administration  of  the  Department  of  Energy  and  analogous  foreign 
counterparts who have interest in our full range of products.

Defense.    The defense segment has wide-ranging needs for HPC systems that in some ways are unique and in other ways are 
similar to our other market segments. HPC systems can assist in the development of defense technologies, equipment and secure 
communications infrastructure, as well as in the identification and analysis of military intelligence. Intelligence supports real-time 
development  of  defense  strategy  and  decision  making,  while  technology  advancements  are  necessary  to  maintain  military 
advantages, including deterrents, and to protect the warfighter.

Earth Sciences.    Weather forecasting and climate modeling applications require increasing speed and larger volumes of data. 
Forecasting models and climate applications have grown increasingly complex with an ever-increasing number of interactive 
variables, making improved supercomputing, analytics and storage capabilities increasingly critical. We have a number of customers
running weather and climate applications, including customers in Germany, the United Kingdom, Korea, Brazil, Switzerland, 
Singapore, Denmark, Finland, India, Spain and the United States.

Energy.    Supercomputing in the energy sector is driven largely by oil and gas exploration and processing, from seismic 
analysis to reservoir simulations. The simulation methods used often require high performance networks and storage subsystems. We 
currently have commercial customers utilizing both our systems and storage solutions in production and we are targeting this 
segment for future products.

Financial Services.    Big data analytics and supercomputing systems are providing competitive advantage in areas as disparate 
as trading, compliance, marketing optimization and risk analysis. Financial services applications are very time sensitive, so high 
performance data analytics solutions are highly sought after. Our customers are using a range of our solutions and systems to derive 
a competitive advantage in this segment.

Life Sciences.    The life sciences industry has demanding data and simulation requirements that test the limits of HPC and big 
data systems. In the life sciences, HPC methods cover a vast area ranging across modeling systems from the molecular level to the 
whole cell, next-generation genomic sequencing and healthcare optimization. Big data analytics are key to making sense and 
creating insight in the enormous volumes of data being generated. Our big data solutions can help discover new relationships that
can allow existing drugs to help address new medical issues. Our customers are utilizing our products and solutions across these
ranges of use cases today.

Manufacturing.    Supercomputers are used to design lighter, safer and more durable vehicles, study wind noise and airflow 
around vehicles, improve airplane flight characteristics and, in many other computer-aided engineering applications, to improve

6

time-to-market and product quality. We currently have aerospace, automotive and manufacturing customers around the globe that are
actively using our HPC and big data solutions.

Emerging Markets.    The rise of big data analytics, artificial intelligence and cyber analytics across industries has resulted in 
growing interest in Cray supercomputers. Artificial intelligence is rapidly becoming the next major driver in the HPC market. Deep 
learning and machine learning, both subsets of artificial intelligence, are specific use cases within the broader advanced analytics 
space. Scientific computing is a natural area for both identifying and driving a broader set of deep learning-enabled applications. 
Further, deep learning core computational motifs are rooted in linear algebra and mathematical optimization, which map well to 
long-standing focus areas for systems research within the HPC community. Finally, several use cases in scientific data analysis
typically require large-scale pattern recognition on multi-dimensional image and time series datasets, and machine learning and deep 
learning are emerging as valuable tools to handle these use cases. Deep learning applications run at scale on the Cray XC series and 
Cray CS series supercomputers.

Sales  to  the  U.S.  government  and  system  acquisitions  primarily  funded  by  the  U.S.  government,  or  U.S.  Government, 
accounted for approximately 47% of our total revenue in 2016, 47% of our total revenue in 2015 and 48% of our total revenue in 
2014. Significant customers with over 10% of our annual total revenue were the U.S. Government and a foreign weather center in 
2016 and the U.S. Government in 2015 and 2014. International customers accounted for 46% of our total revenue in 2016, 36% of 
our total revenue in 2015 and 42% of our total revenue in 2014. 

We have four operating segments that are reportable for financial reporting purposes. Segment information and related 
disclosures are set forth in Note 17 — Segment Information in the Notes to Consolidated Financial Statements in Item 15. Exhibits 
and Financial Statement Schedules in Part IV of this annual report on Form 10-K.

Competition 

The broad HPC market is very competitive. We compete with systems builders and resellers of systems that are constructed 
from commodity components using processors manufactured by Intel, NVIDIA, AMD and others. IBM, NEC and Fujitsu also build 
systems  leveraging  their  own  processors.  In  addition,  certain  Chinese  companies  are  investing  significantly  in  HPC  and  are 
becoming more aggressive and \competitive in the HPC global arena. Our competitors include the previously named companies as 
well as smaller companies that assemble systems from commercially available commodity products. The Cray CS400 and CS-Storm 
supercomputing cluster products are designed to help us better address this market by providing flexible HPC offering alternatives 
with  competitive  pricing. To  the  extent  that  IBM  and  other  processor  suppliers  develop  processors  or  networks  with  greater 
capabilities or at lower cost than the processors we use from Intel and NVIDIA, our systems may be at a competitive disadvantage to 
systems utilizing such other processors. 

For our products designed for the high-end supercomputer market segment, we compete primarily on the basis of product 
performance, scalability, breadth of features, price/performance, total cost of ownership, quality, reliability, upgradability, service 
and support, corporate reputation, brand image and account relationships. Our market approach here is more focused than many of
our competitors, with high-end supercomputing products (the Cray XC series) designed with high levels of integration to meet the
exacting needs of this performance and scalability driven market. We work to offer systems that provide greater performance on the 
largest, most difficult computational problems and superior price/performance on many important applications in the upper-end of
the supercomputer market segment. Our highly-integrated systems often offer superior total cost of ownership advantages as they
typically use less electric power, require less cooling and occupy less space than lower bandwidth cluster systems. 

The market for our Cray CS400 product line is very competitive. The majority of competition is from Lenovo, HPE, Dell, Atos 
and Fujitsu, all of which offer open-standards cluster solutions to address the growth in the mid-range supercomputing market. We 
compete  primarily  on  the  basis  of  price/performance,  open-standards  architecture,  flexible  configurations,  energy-efficiency, 
reliability, scalability, comprehensive cluster management, corporate reputation and account relationships. Our market approach is to 
offer  cluster  solutions  that  provide  greater  performance  on  the  large  and  complex  computational  problems  and  superior 
price/performance on many important applications in this market segment. 

The competitive landscape in the big data market is quite varied, with competition from vendors offering integrated solutions, 
such as Oracle, commodity cluster systems with either open source or proprietary data analytics software, and traditional business 
intelligence vendors such as Teradata, Oracle, IBM and SAP. The market for knowledge discovery through graph analytics is still
nascent and fragmented as no dominant applications have yet emerged, with the result that custom and open source software 
approaches such as Hadoop/MapReduce are often used. However, customers with large, mission-critical graph problems have 
discovered  that  commodity  approaches  do  not  scale  or  deliver  results  in  an  acceptable  timeframe,  and  have  recognized  the 
advantages of specialized solutions. We recently introduced the Cray Urika-GX offering, which competes primarily on the basis of

7

 
 
performance, scalability and integration, as well as total cost of ownership in the traditional Hadoop and Spark analytics marketplace 
as well as for graph analytics. The artificial intelligence market is nascent outside of the large web companies but competition may 
include systems and subsystems developed by processor vendors and several start-up companies in addition to our traditional system 
competitors. 

Our storage products compete with a number of manufacturers and integrators of parallel storage solutions, including IBM 
with its GPFS parallel file system, as well as solutions from Data Direct Networks, or DDN, NetApp, Dell/EMC and other storage 
companies. The parallel storage and file system market is currently fragmented with a number of competing providers in the HPC 
marketplace. We believe that our strong storage products, along with our extensive experience and excellent reputation as an HPC
systems vendor, and our storage offerings compete effectively against our competition, especially when the prospective target 
market overlaps with our HPC systems target market. 

Intellectual Property 

We attempt to protect our trade secrets and other proprietary rights through formal agreements with our employees, customers, 
suppliers and consultants, and through patent protection. Although we intend to protect our rights vigorously, there can be no 
assurance that our contractual and other security arrangements will be successful. 

Our general policy is to seek patent protection for those inventions and improvements that give us a competitive advantage and 
are likely to be incorporated into our products and services. We have a number of patents and pending patent applications relating to 
our hardware and software technologies. While we believe our patents and applications have value, no single patent or group of 
patents is in itself essential to us as a whole or to any of our key products. Any of our proprietary rights could be challenged,
invalidated or circumvented and may not provide significant competitive advantage. 

We have licensed certain patents and other intellectual property from others in our industry. These licenses often contain 
restrictions on our use of the underlying technology. We have also entered into cross-license arrangements with other companies
involved in the HPC industry. 

Backlog 

We do not believe backlog is a meaningful indicator of our future business prospects due to the uncertainty of converting 
orders into recognized revenue in any given period. Judgments about contracts not yet signed and open opportunities are often more
important. Factors impacting the amount of backlog and our ability to recognize revenue from backlog in any given period include
the possibility of significant contract amendments, the timing of our product development, manufacturing and delivery schedules
and changes in delivery schedules requested by our customers. Therefore, we believe that backlog information is not material to an 
understanding of our overall business. 

Employees 

As of December 31, 2016, we had 1,312 employees. We have no collective bargaining agreement with our employees. We 

have not experienced a work stoppage and believe that our employee relations are very good.

Item 1A. Risk Factors

In addition to the other information contained in this annual report on Form 10-K, you should carefully read and consider the 
following risk factors. If any of these risks actually occur, our business, financial condition or operating results could be materially
adversely affected and the trading price of our common stock could decline. 

Our operating results fluctuate significantly and we may not achieve profitability in any given period. Our operating 
results are subject to significant fluctuations which make predicting revenue and operating results for any specific period very
difficult, particularly because a material portion of product revenue recognized in any given quarter or year typically depends on a 
limited number of system sales expected for that quarter or year and the product revenue generally depends on the timing of product 
acceptances by customers and contractual provisions affecting revenue recognition. Receiving less than anticipated customer orders
for delivery and acceptance of product for a particular period, delays in achieving customer acceptances of installed systems and 
recognizing  revenue  from  a  product  transaction  or  transactions  due  to  development  or  product  delivery  delays,  unexpected 
manufacturing delays or defects, not receiving needed components on time or not receiving them with anticipated quality and 
performance or the inability of a system to meet performance requirements or targets or other contractual obligations, among other 
factors, could have a material adverse effect on our operating results in any specific quarter or year, such as by reducing or delaying 
associated revenue, gross profit and cash receipts from one quarter to another, or even from one year to another in the case of
revenue expected to be realized in the fourth quarter of any year, as occurred in the fourth quarter of 2014. In addition, because our 
revenue can be concentrated in particular quarters, often the fourth quarter, rather than evenly spread throughout a year, we generally 
do not expect to sustain profitability over successive quarters even if we are profitable for the year.

Although we have recorded positive annual net income since 2010, we experienced net losses in earlier periods and could 
experience a net loss in any future year in addition to quarterly losses. Net income may fluctuate significantly as a result of many 
factors, including as a result of significant investments we may make to grow our business even though the benefits of those 
investments often require many years to come to fruition and may not be realized when expected or at all. For example, we 
anticipate incurring significant expenditures in connection with the expansion of our facilities and continued investments in research 
and development. Due to the inherent difficulty in estimating costs associated with projects of this scale and nature, certain of the 
costs associated with these potential projects may be higher than estimated and it may take longer than expected to complete, if at 
all. In addition, while we were profitable in 2016, our revenue and profitability declined year over year, driven in part by a slow-
down in the high-end of the supercomputing market. It is uncertain whether or when the high-end of the supercomputing market will
rebound and resume growing. 

Whether we will be able to increase our revenue and achieve and sustain profitability on a quarterly and annual basis depends 

on a number of factors, including: 

•

•

•

•

•

•

•

•

•

our ability to secure sufficient orders for our Cray XC and Cray CS systems as well as upgrades and successor 
systems, such as our next generation “Shasta” system; 

successfully delivering and obtaining sufficient customer acceptances of our Cray XC and Cray CS systems, including 
attached Sonexion storage systems; 

our  ability  to  successfully  generate  revenue  and  profitability  from  sales  of  our  analytics  and  storage and  data 
management products, as well as upgrades and successor systems; 

our ability to successfully and timely design for, procure and integrate competitive processors for our Cray XC and 
Cray CS systems and upgrades and successor systems;  

our expense levels, including research and development expense net of government funding; 

delays in delivery of upgraded or new systems, longer than expected customer acceptance cycles or penalties resulting 
from system acceptance issues;  

our ability to efficiently scale our internal processes to meet necessary peak requirements and growth in our 
business; 

the level of revenue recognized in any given period, which is affected by the very high average sales prices and limited 
number of significant system sales and resulting potential acceptances in any quarter, the timing of product orders and 
acceptances by customers and contractual provisions affecting the timing and amount of revenue recognition; 

our ability to continue to broaden our customer base beyond our traditional customers;  

9

•

•

•

•

revenue delays or losses due to customers postponing purchases as a result of delays in available budgets or waiting 
times related to the availability of future upgraded or new systems, including those containing new processors;  

the  level  of  product  gross  profit  contribution  in  any  given  period  due  to  volume,  competition  or  product  mix, 
particularly  with  the  introduction  of  flexible  commodity-based  supercomputers,  competitive  factors,  strategic 
transactions, product life cycle, currency fluctuations, acceptance penalties and component costs; 

the competitiveness of our products, services and prices; 

our ability to secure additional government funding for future development projects; 

• maintaining  and  successfully  completing  our  product  development  projects  on  schedule  and  within  budgetary 

limitations; 

•

•

•

our  ability  to  resolve  and  the  costs  incurred  in  connection  with  any  actual  or  alleged  issues  with  our  products, 
including third-party components of such products, such as those that relate to product defects or intellectual property 
rights;  

the level and timing of maintenance contract renewals with existing customers; and 

the terms and conditions of sale or lease for our products and services. 

The receipt of orders and the timing of shipments and acceptances impacts our quarterly and annual results, including cash 

flows, and is affected by events outside our control, such as: 

•

•

•

•

•

•

•

•

•

•

•

whether or when the high-end of the supercomputing market, which is currently experiencing a slow-down, rebounds 
and resumes growing; 

the timely availability of acceptable components, including, but not limited to, processors, in sufficient quantities to 
meet customer delivery schedules and other customer commitments at a competitive cost; 

the  timing  and  level  of  government  funding  and  resources  available  for  product  acquisitions  and  research  and 
development contracts, which have been, and may continue to be, adversely affected by the current global economic 
and fiscal uncertainties, increased governmental budgetary limitations and disruptions in the operations of the United  
States and other governments; 

competitor and supplier pricing strategies; 

currency fluctuations, international conflicts or economic crises, including the ongoing economic challenges in the 
United States, Japan and Europe, and fluctuations in oil prices that can affect the resources available to potential 
customers to purchase products; 

new tariffs or taxes imposed on components and products sourced or manufactured outside of the United States; 

the introduction or announcement of competitive or key industry supplier products; 

price fluctuations or product shortages in the processors and other commodity electronics and memory markets; 

the availability of adequate customer facilities to install and operate new Cray systems;  

general economic trends, including changes in levels of customer capital spending; and 

our customers’ ability to make future payments in accordance with contractual terms of their purchase or sales-type 
lease agreements. 

Because of the numerous factors affecting our revenue and results of operations, we may not achieve profitability on a 
quarterly or annual basis in the future. We anticipate that our quarterly results will fluctuate significantly, and include losses, even in 
years where we expect or achieve positive annual net income. Delays in the availability of acceptable third-party components, 
product  development,  receipt  of  orders,  product  acceptances,  issues  with  third-party  component  performance  or  reliability, 
reductions in outside funding for our research and development efforts, a reduction in the size of the high-end of the supercomputing 
market, the level and timing of approved government fiscal budgets and achieving contractual development milestones have had a 
substantial adverse effect on our past results and are expected to continue to have such an effect on our results in 2017 and in future 
years.

10

If we are unable to successfully develop, sell and deliver our Cray XC systems and successor systems, such as our next 
generation Shasta system, and recognize revenue for these systems, our operating results will be adversely affected. We 
expect that a substantial portion of our revenue in the foreseeable future will come from acceptances of delivered Cray XC systems 
and successor systems, such as our next generation Shasta system, including systems integrating future processors and accelerators 
where we are dependent upon third-party suppliers to deliver according to expected plans. The development efforts related to these
systems are lengthy and technically challenging processes, and require a significant investment of capital, engineering and other
resources often years ahead of the time when we can be assured that they will result in competitive products. We may invest 
significant resources that may prove ultimately unsuccessful. Unanticipated performance and/or development issues may require 
more engineers, time or testing resources than are currently available. Given the breadth of our engineering challenges, changes in 
the market and technology and our limited engineering and technical personnel resources, we periodically review the anticipated
contributions and expense of our product programs to determine their long-term viability, and we may substantially modify or 
terminate one or more development programs. We may not be successful in meeting our development schedules for technical 
reasons, including those related to our dependence on third-party suppliers of components such as processors and accelerators, 
and/or because of insufficient engineering resources, which could result in an uncompetitive product or cause a lack of confidence in 
our capabilities among our key customers. To the extent that we incur delays in completing the design, development and production 
of hardware components, delays in development of requisite system software, cancellation of or changes to programs due to 
technical or economic infeasibility, inability to source acceptable third-party components such as processors and accelerators or 
investment in unproductive development efforts, our revenue, results of operations and cash flows, and the reputation of such 
systems in the market, could be adversely affected.

In  addition,  many  factors  affect  our  ability  to  successfully  sell  and  recognize  revenue  for  these  systems,  including  the 

following: 

•

•

•

•

the level of product differentiation in our Cray XC systems and successor systems, such as our next generation Shasta 
system. We need to compete successfully against HPC systems from both large, established companies and smaller 
companies and demonstrate the value of our balanced, tightly integrated systems to our customers in a variety of 
markets; 

our ability to meet all customer requirements for acceptance. Even once a system has been delivered, we sometimes do 
not meet all of the contract requirements for customer acceptance and ongoing reliability of our systems within the 
provided-for acceptance period, which has resulted in contract penalties and delays in our ability to recognize revenue 
from system deliveries. Most often these penalties have adversely affected revenue and gross profit at the time of 
revenue recognition through the provision of additional equipment and services and/or service credits to satisfy 
delivery delays and performance shortfalls. The risk of contract penalties is increased when we bid for new business 
prior to us or our suppliers completing development of new products and when we must estimate future system 
performance, such as has been required with our Cray XC systems and our Sonexion storage systems, and will be 
frequently required for subsequent systems, such as our next generation Shasta system;  

our ability to source competitive, key components in appropriate quantities (to have enough to sell without ending up 
with  excess  inventory  that  can  lead  to  obsolescence  charges),  in  a  timely  fashion  and  on  acceptable  terms  and 
conditions and that meet the performance criteria required; and  

whether potential customers delay purchases of our products because they decide to wait for successor systems or 
upgrades that we or our suppliers have announced or they believe will be available in the future. 

Failure to successfully develop and sell our Cray XC systems and successor systems, such as our next generation Shasta 

system, into the supercomputing market and recognize revenue for such systems will adversely affect our operating results. 

If our current and future products targeting markets outside of our traditional markets, primarily products targeting 
the big data and commercial markets, are not successful, our ability to grow or even maintain our revenues and achieve and 
sustain profitability will be adversely affected. Our ability to materially grow or even maintain our revenues and achieve and 
sustain profitability will be adversely affected if we are unable to generate sufficient revenue from products targeting markets
outside of our traditional markets, including if those market segments do not grow significantly. We are currently focusing on big 
data analytics, artificial intelligence and storage and data management opportunities as well as the commercial market for all of our 
products. To grow our revenue from opportunities outside our primary markets, we must successfully and in a cost-effective manner 
design and develop products utilizing technologies different from our traditional supercomputing products, compete successfully
with many established companies and new entrants in these markets, continue to win awards for new contracts, timely perform on 
existing contracts, develop our capability for broader market sales and business development and successfully develop and introduce
new solution-oriented offerings, notwithstanding that these are relatively new businesses for us and we do not have significant

11

experience targeting these markets. Big data analytics, artificial intelligence and storage and data management opportunities require 
significant monetary investments ahead of revenue, including product development efforts, adding experienced personnel and 
initiating new marketing and sales efforts and therefore may reduce net income in the short term even if successful.

Our reliance on third-party suppliers poses significant risks to our operating results, business and prospects. We rely 
upon third-party vendors, particularly Intel, to supply processors, including accelerators, and for most of the products, we sell and 
use service providers to co-develop key technologies. We subcontract the manufacturing of a majority of the hardware components
for our high-end products, including integrated circuits, printed circuit boards, memory parts, cables and power supplies, on a sole or 
limited source basis to third-party suppliers. We use contract manufacturers to assemble certain important components for all of our 
systems. We also rely on third parties to supply key software and hardware capabilities, such as file systems, solution-specific
servers and storage subsystems, and in the case of our Sonexion products, we rely on third-party original equipment manufacturers 
to supply complete storage systems. Because specific components must be designed into our systems well in advance of initial 
deliveries of those systems, we are particularly reliant on our processor vendors, particularly Intel, to deliver on the capabilities and 
pricing expected at the time we design key elements of the system and make binding bids to customers. We are subject to substantial
risks because of our reliance on these and other limited or sole source suppliers, including the following risks:

•

•

•

•

•

•

•

•

•

if a supplier does not provide components or systems that meet our or their specifications in sufficient quantities and 
with acceptable performance or quality on time or deliver when required, or delays future components or systems 
beyond anticipated delivery dates, then sales, production, delivery, acceptance and revenue from our systems could be 
delayed and/or reduced and we could be subject to costly penalties even once delivered and accepted, which has 
happened multiple times in the past and has at times significantly lowered our revenue for a particular quarter or year; 

if our relationship with a key supplier, such as Intel, is adversely affected, for example, due to competitive pressures 
(or conflicting interests), our ability to obtain components on competitive financial terms could be adversely affected; 

if a supplier cannot provide a competitive key component, for example, due to inadequate performance or a prohibitive 
price, or eliminates key features from components, such as with the processors we design into our systems, our 
systems may be less competitive than systems using components with greater capabilities; 

if  an  interruption  of  supply  of  our  components,  services  or  capabilities  occurs  because  a  supplier  changes  its 
technology roadmap, suffers damage to its manufacturing facilities, decides to no longer provide those products or 
services, increases the price of those products or services significantly or imposes reduced delivery allocations on its 
customers, it could take us a considerable period of time to identify and qualify alternative suppliers, to redesign our 
products as necessary and to begin to manufacture the redesigned components or otherwise obtain those services or 
capabilities. In some cases, such as with key integrated circuits and memory parts or processors, we may not be able to 
redesign such components or find alternate sources that we could use in any realistic timeframe; 

if a supplier plans future processors that are made available in a way that encourages customers to delay purchases of 
our products because they decide to wait for successor systems or upgrades they believe will be available in the future 
or to purchase products with the future processors from our competitors who are willing to take greater risk on 
delivery;  

if Cray systems at customer sites develop significant issues with third-party components, as has occurred, the cost to 
Cray  to  repair  or  replace  the  components  or  otherwise  address  such  issue  may  be  material. If  we  are  unable  to 
effectively address such problem or a problem causes customer disruption, our relationship with our customers may 
also be harmed; 

if a supplier of a component is subject to a claim that the component infringes a third-party’s intellectual property 
rights, as has happened with multiple suppliers, our ability to obtain necessary components could be adversely affected 
or our cost to obtain such components could increase significantly; 

if a supplier providing us with key research and development and design services or core technology components with 
respect to integrated circuit design, network communication capabilities or software is late, fails to provide us with 
effective  functionality  or  loses  key  internal  talent,  our  development  programs  may  be  delayed  or  prove  to  be 
impossible to complete; 

if a supplier provides us with hardware or software that contains bugs or other errors or defects, or is different from 
what we expected, our development projects and production systems may be adversely affected through reduced 
performance or capabilities, additional design testing and verification efforts, re-spins of integrated circuits and/or 

12

•

•

development of replacement components, and the production and sales of our systems could be delayed and systems 
installed at customer sites could require significant, expensive field component replacements or result in penalties; 

some of our key component and service suppliers are small companies with limited financial and other resources, and 
consequently may be more likely to experience financial and operational difficulties than larger, well-established 
companies, which increases the risk that they will be unable to deliver products as needed; and 

if a key supplier is acquired or has a significant business change, as has occurred in the past with the acquisition of the 
third-party original equipment manufacturer that supplies complete storage systems for our Sonexion product, the 
production and sales of our systems and services may be delayed or adversely affected, or our development programs 
may be delayed or may be impossible to complete. 

Delays in the availability of components with acceptable performance, features and reliability, or our inability to obtain such
acceptable components in the quantities we need or at all, and increases in prices and order lead times for certain components, have 
occurred in the past, and we are currently experiencing increased delivery timelines of memory and other key components. These 
types of issues have adversely affected our revenue and operating results in multiple prior periods, in some cases significantly, and 
could adversely affect future results. 

The continuing commoditization of HPC hardware and software has resulted in increased pricing pressure and may 
adversely affect our operating results. The continuing commoditization of HPC hardware, such as processors, interconnects, 
storage and other infrastructure, and the growing commoditization of software, including plentiful building blocks and more capable
open source software, as well as the potential for integration of differentiated technology into already-commoditized components,
has resulted in, and may result in increased pricing pressure that may cause us to reduce our pricing in order to remain competitive, 
which can negatively impact our gross margins and adversely affect our operating results.

If the U.S. government and other governments purchase, or fund the purchase of, fewer supercomputers or delay such 
purchases, our revenue would be reduced and our operating results would be adversely affected. Historically, sales to the U.S. 
Government have represented the largest single market segment for supercomputer sales worldwide, including our products and 
services. In 2014, 2015 and 2016, approximately 48%, 47% and 47%, respectively, of our total revenue was derived from such sales.
Our plans for the foreseeable future contemplate significant sales to the U.S. Government. Sales to the U.S. Government and other
governments, including further sales pursuant to existing contracts, have been, and may continue to be, adversely affected by factors
outside our control, such as by:

•

•

•

•

•

•

•

•

•

•

•

•

uncertainties relating to priorities of the new administration or adverse decisions by the new administration to reduce 
or eliminate budgets for governmental agencies or departments that purchase or fund the purchase of our products and 
services;

Congressional decisions in addressing budget concerns and current economic uncertainty;  

disruptions in the operations of the U.S. government, including impacts of the new administration; 

“sequestration”;

the downgrading of U.S. government debt or the possibility of such action; 

the political climate in the U.S. focusing on cutting or limiting budgets and its affect on government budgets;  

the limits on federal borrowing capacity;  

changes in procurement policies;  

budgetary considerations, including Congressional delays in completing appropriation bills as has occurred in the past 
and which is the case right now as Congress is operating under a Continuing Resolution at fiscal year 2016 levels until 
April 28, 2017; 

domestic crises; 

political efforts to limit the activities of U.S. intelligence community agencies, including proposed state legislation that 
would  limit  or  even  criminalize  doing  business  with  the  NSA  for  certain  companies  doing  business  with  state 
governments; and  

international political developments, such as the downgrading of European debt or the U.K. “Brexit” vote.  

13

If agencies and departments of the United States or other governments were to stop, reduce or delay their use and purchases 

of supercomputers, our revenue and operating results would be adversely affected. 

If our cluster systems are not successful, our operating results will be adversely affected. Our cluster products were first 
introduced in late 2012. We have had relatively limited experience selling cluster-based solutions, including into the same markets 
we sell our core supercomputers, and if we cannot successfully sell these solutions with acceptable margins, our operating results
will be adversely affected.

We may infringe or be subject to claims that we infringe the intellectual property rights of others. We are and may in the 
future be subject to patent infringement and other intellectual property claims and lawsuits in various jurisdictions, and we cannot be 
certain that our products or activities do not violate the patents, trademarks, or other intellectual property rights of third-party 
claimants. Companies in the technology industry and other patent, copyright, and trademark holders seeking to profit from royalties
in connection with grants of licenses own large numbers of patents, copyrights, trademarks, domain names, and trade secrets and
frequently commence litigation based on allegations of infringement, misappropriation, or other violations of intellectual property or 
other rights. As we face increasing competition and gain an increasingly high profile, the intellectual property rights claims against 
us have grown and will likely continue to grow. For example, we are currently involved in litigation with Raytheon Company, or 
Raytheon, which is described in Note 12 - Commitments and Contingencies in the Notes to Consolidated Financial Statements in 
Item 15. Exhibits and Financial Statement Schedules in Part IV of this annual report on Form 10-K.

 We intend to vigorously defend and prosecute these litigation matters and, based on our reviews to date, we believe we have 
valid defenses with respect to each of these matters. However, litigation is inherently uncertain, and any judgment or injunctive
relief entered against us or any adverse settlement could materially and adversely impact our business, financial condition, operating 
results, and prospects. As a result of these or other intellectual property infringement claims, we could be required or otherwise
decide that it is appropriate to: 

•

•

•

•

•

pay third-party infringement claims; 

discontinue manufacturing, using or selling particular products subject to infringement claims; 

discontinue using the technology or processes subject to infringement claims; 

develop other technology not subject to infringement claims, which could be time-consuming and costly or may not 
be possible; and/or 

license technology from the third-party claiming infringement, which license may not be available on commercially 
reasonable terms, or at all. 

In addition, litigation can involve significant management time and attention and can be expensive, as it has been with 
Raytheon, regardless of outcome. During the course of these litigation matters, there may be announcements of the results of 
hearings and motions, and other interim developments related to the litigation matters. If securities analysts or investors regard these 
announcements as negative, the market price of our common stock may decline. 

If we cannot retain, attract and motivate key personnel, we may be unable to effectively implement our business 
plan. Our success depends in large part upon our ability to retain, attract and motivate highly skilled management, development, 
marketing, sales and service personnel. The loss of and failure to replace key technical management and personnel could adversely 
affect multiple development efforts. Recruitment and retention of senior management and skilled technical, sales and other personnel 
is very competitive, and we may not be successful in either attracting or retaining such personnel. We have lost key personnel to 
other  high  technology  companies,  and  many  larger  companies  with  significantly  greater  resources  than  us  have  aggressively 
recruited, and continue to aggressively recruit, key personnel. As part of our strategy to attract and retain key personnel, we may 
offer equity compensation through grants of stock options, restricted stock awards or restricted stock units. Potential employees,
however, may not perceive our equity incentives as attractive enough. In addition, due to the intense competition for qualified
employees, we may be required to, and have had to, increase the level of compensation paid to existing and new employees, which
could materially increase our operating expenses.

We have made in the past, and may make in the future, acquisitions which could require significant management 
attention, disrupt our business, result in dilution to our shareholders, deplete our cash reserves and adversely affect our 
financial results. Acquisitions involve numerous risks, including the following:

•

•

difficulties in successfully integrating the operations, systems, technologies, products, offerings and personnel of the 
acquired company or companies; 

insufficient revenue to offset increased expenses associated with acquisitions; 

14

 
•

•

•

•

•

diversion of management’s attention from normal daily operations of the business and the challenges of managing 
larger and more widespread operations resulting from acquisitions; 

potential difficulties in completing projects associated with in-process research and development intangibles; 

difficulties in entering markets in which we have no or limited direct prior experience and where competitors in such 
markets have stronger market positions; 

initial dependence on unfamiliar supply chains or relatively small supply partners; and 

the potential loss of key employees, customers, distributors, vendors and other business partners of the companies we 
acquire following and continuing after announcement of acquisition plans. 

Acquisitions may also cause us to: 

•

•

•

•

•

•

•

use a substantial portion of our cash reserves or incur debt; 

issue equity securities or grant equity incentives to acquired employees that would dilute our current shareholders’ 
percentage ownership; 

assume liabilities, including potentially unknown liabilities; 

record goodwill and non-amortizable intangible assets that are subject to impairment testing on a regular basis and 
potential periodic impairment charges; 

incur amortization expenses related to certain intangible assets; 

incur large and immediate write-offs and restructuring and other related expenses; or 

become subject to intellectual property litigation or other litigation. 

Acquisitions of high-technology companies and assets are inherently risky and subject to many factors outside of our control, 
and no assurance can be given that our recently completed or future acquisitions will be successful and will not materially adversely 
affect  our  business,  operating  results,  or  financial  condition.  Failure  to  manage  and  successfully  integrate  acquisitions  could
materially harm our business and operating results. 

If we are unable to compete successfully in the highly competitive HPC market, our business will not be successful. The 
market for HPC systems is very competitive. An increase in competitive pressures in our market or our failure to compete effectively 
may  result  in  pricing  reductions,  reduced  gross  margins  and  loss  of  market  share  and  revenue.  Many  of  our  competitors  are 
established well known companies in the HPC market, including IBM, HPE, Lenovo, Dell, NEC, Hitachi, Fujitsu and Atos. Most of 
these competitors have substantially greater research, engineering, manufacturing, marketing and financial resources than we do. In 
addition, certain Chinese companies are investing significantly in HPC and are becoming more aggressive and more competitive in
the HPC global arena.

We also compete with systems builders and resellers of systems that are constructed from commodity components using 
processors manufactured and/or designed by Intel, ARM, AMD, NVIDIA and others. These competitors include the companies 
named above, as well as smaller companies that benefit from the low research and development costs needed to assemble systems 
from commercially available commodity products. Such companies, because they can offer high peak performance per dollar, can 
put pricing pressure on us in certain competitive procurements. In addition, to the extent that Intel, IBM and other processor 
suppliers develop processors with greater capabilities or at a lower cost than the processors we currently use, our Cray XC systems 
may be at a competitive disadvantage to systems utilizing such other processors until we can design in, integrate and secure 
competitive processors, if at all. Also, to the extent any component supplier successfully adds differentiating capabilities to their 
HPC products that compete with what we provide, we may experience greater competitive pressures. 

Our growth initiatives in the big data analytics, artificial intelligence and storage and data management markets must also 
compete successfully with many established companies and new entrants, many of whom have significantly greater resources and 
brand recognition in these markets than we do. 

Periodic announcements by our competitors of new HPC, storage or data analytics systems or plans for future systems and 
price adjustments may reduce customer demand for our products. Many of our potential customers already own or lease high 
performance computer, storage or data analytics systems. Some of our competitors have offered substantial discounts to potential
customers. We have in the past been and may again be required to provide substantial discounts to make strategic sales, which may
reduce or eliminate any gross profit on such transactions, or require us to provide lease financing for our products, which could

15

result in a multi-year deferral of our receipt of cash and revenue for these systems. These developments limit our revenue and 
financial resources and reduce our ability to be profitable and grow. 

We maintain confidential and proprietary information on our computer networks and employ security measures 
designed  to  protect  this  information  from  unauthorized  access.  If  our  security  measures  are  breached,  we  could  lose 
proprietary data and may suffer economic losses. We maintain confidential information on our computer networks, including 
information and data that are proprietary to our customers and third parties, as well as to us. Although we have designed and 
employed and continue to enhance a multitude of security measures to protect this information from unauthorized access, security
breaches may occur, and in the past have occurred, as a result of third-party action, including computer hackers, employee error, 
malfeasance or otherwise. Security breaches can result in someone obtaining unauthorized access to our data or our customers’ data,
including our intellectual property and other confidential business information. Because the techniques employed by hackers to 
obtain  unauthorized  access  or  to  sabotage  systems  change  frequently,  we  may  be  unable  to  anticipate  these  techniques  or  to 
implement  adequate  preventative  measures. A  security  breach  could  result  in  disclosure  of  our  trade  secrets  or  disclosure  of 
confidential customer, supplier or employee data. If this should happen, we could be exposed to potentially significant legal liability, 
remediation expense, harm to our reputation and other harm to our business.

We may not be able to protect our proprietary information and rights adequately. We rely on a combination of patent, 
copyright, trademark and trade secret protection, nondisclosure agreements and licensing arrangements to establish, protect and
enforce our proprietary information and rights. We have a number of patents and have additional applications pending. There can be 
no assurance, however, that patents will be issued from the pending applications or that any issued patents will adequately protect 
those aspects of our technology to which such patents will relate. Despite our efforts to safeguard and maintain our proprietary
rights, we cannot be certain that we will succeed in doing so or that our competitors will not independently develop or patent 
technologies that are substantially equivalent or superior to our technologies. The laws of some countries do not protect intellectual
property rights to the same extent or in the same manner as do the laws of the United States. Additionally, under certain conditions, 
the U.S. government might obtain non-exclusive rights to certain of our intellectual property. Although we continue to implement
protective measures and intend to defend our proprietary rights vigorously, these efforts may not be successful.

We are subject to market and financial risks due to our international operations that could adversely affect those 
operations or our profitability and operating results. Our international operations include sales and service offices in Europe, the 
Middle East, South America, Asia, Australia and Canada. Our operations in countries outside of the United States, which accounted
for approximately 46% of our total revenue for 2016, expose us to greater risks associated with international sales and operations. 
Our profitability and international operations are, and will continue to be, subject to a number of risks and potential costs, including:

•

•

•

•

•

•

•

•

•

•

supporting multiple languages; 

recruiting sales and technical support personnel internationally with the skills to sell and support our products; 

complying with governmental regulations, including obtaining required import or export approval for our 
products; 

increased complexity and costs of managing international operations; 

increased exposure to foreign currency exchange rate fluctuations; 

trade protection measures and business practices that favor local competition; 

longer sales cycles and manufacturing lead times; 

financial risks such as longer payment cycles and difficulties in collecting accounts receivable; 

difficulties associated with repatriating cash generated or held abroad in a tax-efficient manner; 

ineffective legal protection of intellectual property rights; 

• more complicated logistics and distribution arrangements; 

•

•

•

•

additional taxes and penalties; 

inadequate local infrastructure that could result in business disruptions; 

global political and economic instability; and 

other factors beyond our control such as natural disasters, terrorism, civil unrest, war and infectious disease. 

16

Our global operations are also subject to numerous U.S. and foreign laws and regulations, including those related to anti-
corruption, tax, corporate governance, imports and exports, financial and other disclosures, privacy and labor relations. These laws 
and regulations are complex and may have differing, conflicting and evolving legal standards, making compliance difficult and 
costly. If we or our employees, contractors or agents violate these laws and regulations, we could be subject to fines, penalties or 
criminal sanctions and may be prohibited from conducting business in one or more countries. Any violations, individually or in the 
aggregate, could have a material adverse effect on our operations and financial condition. 

In addition, on June 23, 2016, the United Kingdom held a referendum in which voters approved an exit from the European 
Union, commonly referred to as “Brexit.” As a result of the referendum, it is expected that the British government will begin 
negotiating  the  terms  of  the  United  Kingdom’s  future  relationship  with  the  European  Union. The  negotiated  measures  could 
potentially disrupt some of our target markets and jurisdictions in which we operate, including the United Kingdom and Germany,
such as by adversely affecting tax benefits or liabilities in these or other jurisdictions or by restricting the movement of employees 
between the United Kingdom and other countries. Any such changes may adversely affect our operations and financial results. 

Customers and other third parties may make statements speculating about or announcing the purchase, acceptance or 
intention to complete purchases or acceptances of our products before such purchases or acceptances are substantially 
certain, and these proposed purchases or acceptances may not be completed when or as expected, if at all. From time to time, 
customers and other third parties may make statements speculating about or announcing a potential purchase of our products before
we have obtained an order for such purchases or completed negotiations and signed a contract for the purchase of such products. In 
some instances, government and government-funded customers may announce possible purchases even before they have obtained 
the necessary budget to procure the products. As a result, these statements, postings or announcements do not mean that we will
ultimately be able to secure the sale when or as expected or at all as it is not certain that the contract or order negotiations will be 
completed successfully or as expected or that the customer will be able to obtain the budget they hope for or expect. In addition, 
from time to time, customers and other third parties may make statements speculating about or announcing the completion of an 
acceptance  process  of  a  delivery  system  before  such  acceptance  is  completed  or  certain.  As  a  result,  these  statements  or 
announcements do not mean that we will ultimately be able to obtain the acceptance when or as expected or recognize revenue.

We are subject to increasing government regulations and other requirements due to the nature of our business, which 
may adversely affect our business operations. In 2014, 2015 and 2016, approximately 48%, 47% and 47%, respectively, of our 
total revenue was derived from the U.S. Government. In addition to normal business risks, our contracts with the U.S. government
are subject to unique risks, some of which are beyond our control. Our contracts with the U.S. government are subject to particular 
risks, including:

The funding of U.S. government programs is subject to Congressional appropriations. Many of the U.S. government programs 
in which we participate may extend for several years; however, these programs are normally funded annually. Changes in U.S. 
strategy and priorities may affect our future procurement opportunities and existing programs. Long-term government contracts and 
related  orders  are  subject  to  cancellation,  or  delay,  if  appropriations  for  subsequent  performance  periods  are  not  made.  The 
termination of funding for existing or new U.S. government programs could result in a material adverse effect on our results of
operations and financial condition.

The U.S. government may modify, curtail or terminate its contracts with us. The U.S. government may modify, curtail or 
terminate  its  contracts  and  subcontracts  with  us,  without  prior  notice  at  its  convenience  upon  payment  for  work  done  and 
commitments made at the time of termination. Modification, curtailment or termination of our major programs or contracts could 
have a material adverse effect on our results of operations and financial condition.

Our U.S. government contract costs are subject to audits by U.S. government agencies. U.S. government representatives may 
audit the costs we incur on our U.S. government contracts, including allocated indirect costs. Such audits could result in adjustments 
to our contract costs. Any costs found to be improperly allocated to a specific contract will not be reimbursed, and such costs already 
reimbursed must be refunded. If any audit uncovers improper or illegal activities or non-compliance with the terms of a specific
contract, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture 
of profits, suspension of payments, fines and suspension or prohibition from doing business with the U.S. government.

Our business is subject to potential U.S. government inquiries and investigations. We may be subject to U.S. government 
inquiries  and  investigations  of  our  business  practices  due  to  our  participation  in  government  contracts. Any  such  inquiry  or 
investigation could potentially result in a material adverse effect on our results of operations and financial condition.

Our U.S. government business is also subject to specific procurement regulations and other requirements. These requirements, 
although customary in U.S. government contracts, increase our performance and compliance costs. These costs might increase in the
future, reducing our margins, which could have a negative effect on our financial condition. Failure to comply with these regulations 

17

and requirements could lead to suspension or debarment, for cause, from U.S. government contracting or subcontracting for a period 
of time and could have a negative effect on our reputation and ability to secure future U.S. government contracts.

U.S.  export  controls  could  hinder  our  ability  to  make  sales  to  foreign  customers  and  our  future  prospects. The  U.S. 
government regulates the export of HPC systems such as our products. We have experienced delays for up to several months in 
receiving appropriate approvals necessary for certain sales, which have delayed the shipment of our products. Delay or denial in the 
granting of any required licenses could make it more difficult to make sales to certain foreign customers, eliminating an important 
source of potential revenue. Restrictions on the export of information needed to manufacture our products has in the past impacted 
and could in the future impact our ability to have certain products and components made in certain lower cost jurisdictions

Our stock price is volatile. The trading price of our common stock is subject to significant fluctuations in response to many 
factors, including stock market trends and shareholder profile, our quarterly operating results, changes in analysts’ estimates or our 
outlook, our capital raising activities, announcements of technological innovations and customer contracts by us or our competitors, 
a significant aggressive seller or buyer, litigation activities, general economic conditions and conditions in our industry.  From 
January 1, 2016 through December 31, 2016, the closing sales price of our common stock on the NASDAQ Global Market ranged 
from $18.40 to $43.06 per share, and had a low closing price of $16.35 per share during the period from January 1, 2017 through
February 9, 2017. Because our stock price has been volatile, investing in our common stock is risky.

We incorporate software licensed from third parties into the operating systems for our products as well as in our tools 
to design products and any significant interruption in the availability of these third-party software products or defects in 
these products could reduce the demand for our products or cause delay in development. The operating system as well as other 
software we develop for our supercomputers contains components that are licensed to us under open source software licenses. Our
business could be disrupted if this software, or functional equivalents of this software, were either no longer available to us or no 
longer offered to us on commercially reasonable terms. In either case we would be required to redesign our operating system 
software to function with alternative third-party software, or develop these components ourselves, which would result in increased 
costs and could result in delays in product shipments. Our supercomputer systems utilize software system variants that incorporate 
Linux technology. The open source licenses under which we have obtained certain components of our operating system software 
may not be enforceable. Any ruling by a court that these licenses are not enforceable, or that Linux-based operating systems, or
significant portions of them, may not be copied, modified or distributed as provided in those licenses, would adversely affect our 
ability to sell our systems. In addition, as a result of concerns about the risks of litigation and open source software generally, we 
may be forced to protect our customers from potential claims of infringement. In any such event, our financial condition and results 
of operations may be adversely affected.

We also incorporate proprietary incidental software from third parties, such as for file systems, job scheduling and storage 
subsystems. We have experienced some functional issues in the past with implementing such software with our supercomputer 
systems. In addition, we may not be able to secure needed software systems on acceptable terms, which may make our systems less
attractive  to  potential  customers.  These  issues  may  result  in  lost  revenue,  additional  expense  by  us  and/or  loss  of  customer 
confidence. 

The “conflict minerals” rule of the Securities and Exchange Commission, or SEC, has caused us to incur additional 
expenses, could limit the supply and increase the cost of certain metals used in manufacturing our products, and could make 
us less competitive in our target markets. On August 22, 2012, the SEC adopted a rule requiring disclosure by public companies 
of the origin, source and chain of custody of specified minerals, known as conflict minerals, that are necessary to the functionality or 
production of products manufactured or contracted to be manufactured by us. The rule requires companies to obtain sourcing data
from suppliers, engage in supply chain due diligence, and file annually with the SEC a specialized disclosure report on Form SD
covering the prior calendar year. Implementation of our conflict minerals policy could limit our ability to source at competitive
prices and to secure sufficient quantities of certain minerals used in the manufacture of our products, specifically tantalum, tin, gold 
and tungsten, as the number of suppliers that provide conflict-free minerals may be limited. In addition, we have incurred, and may 
continue to incur, material costs associated with complying with the conflict minerals rule, such as costs related to the determination 
of the origin, source and chain of custody of the minerals used in our products, the adoption of conflict minerals-related governance 
policies, processes and controls, and possible changes to products or sources of supply as a result of such activities. Within our 
supply chain, we may not be able to sufficiently verify the origins of the relevant minerals used in our products through the data
collection and due diligence procedures that we implement, which may harm our reputation. Furthermore, we may encounter 
challenges in satisfying those customers that require that all of the components of our products be certified as conflict free, and if we 
cannot satisfy these customers, they may choose a competitor’s products. We continue to investigate the presence of conflict 
materials within our supply chain.

We are required to evaluate our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act 
of 2002 at the end of each fiscal year, and any adverse results from such future evaluations could result in a loss of investor
confidence in our financial reports and have an adverse effect on our stock price. Pursuant to Section 404 of the Sarbanes-
Oxley Act of 2002, we are required to furnish a report by our management and a report by our independent registered public 
accounting firm on our internal control over financial reporting in our annual reports on Form 10-K as to whether we have any 
material weaknesses in our internal controls over financial reporting. Depending on their nature and severity, any future material 
weaknesses could result in our having to restate financial statements, could make it difficult or impossible for us to obtain an audit of 
our annual financial statements or could result in a qualification of any such audit. In such events, we could experience a number of 
adverse  consequences,  including  our  inability  to  comply  with  applicable  reporting  and  listing  requirements,  a  loss  of  market 
confidence in our publicly available information, delisting from The NASDAQ Global Market, an inability to complete a financing,
loss of other financing sources such as our line of credit, and litigation based on the events themselves or their consequences.

Our reported financial results may be adversely affected by changes in accounting principles generally accepted in the 
United  States.  Generally  accepted  accounting  principles  in  the  United  States  are  subject  to  interpretation  by  the  Financial 
Accounting Standards Board, the SEC and various bodies formed to promulgate and interpret appropriate accounting principles. A 
change in these principles or interpretations could have a significant effect on our reported financial results, and could affect the 
reporting of transactions completed before the announcement of a change.

Provisions of our Restated Articles of Incorporation and Amended and Restated Bylaws could make a proposed 
acquisition of our business that is not approved by our Board of Directors more difficult. Provisions of our Restated Articles of 
Incorporation and Amended and Restated Bylaws could make it more difficult for a third-party to acquire us. These provisions could 
limit the price that investors might be willing to pay in the future for our common stock. For example, our Restated Articles of
Incorporation and Amended and Restated Bylaws provide for:

•

•

•

•

•

•

•

•

removal of a director only in limited circumstances and only upon the affirmative vote of not less than two-thirds of 
the shares entitled to vote to elect directors; 

the ability of our Board of Directors to issue up to 5,000,000 shares of preferred stock, without shareholder approval, 
with rights senior to those of the common stock; 

no cumulative voting of shares; 

the right of shareholders to call a special meeting of the shareholders only upon demand by the holders of not less than 
30% of the shares entitled to vote at such a meeting; 

the affirmative vote of not less than two-thirds of the outstanding shares entitled to vote on an amendment, unless the 
amendment was approved by a majority of our continuing directors, who are defined as directors who have either 
served as a director since August 31, 1995, or were nominated to be a director by the continuing directors; 

special  voting  requirements  for  mergers  and  other  business  combinations,  unless  the  proposed  transaction  was 
approved by a majority of continuing directors; 

special procedures to bring matters before our shareholders at our annual shareholders’ meeting; and 

special procedures to nominate members for election to our Board of Directors. 

These provisions could delay, defer or prevent a merger, consolidation, takeover or other business transaction between us and a
third-party that is not approved by our Board of Directors.

(1) The  shareholders  approved  our  1995,  1999  and  2003  stock  option  plans,  our  2004,  2006  and  2009  long-term  equity 
compensation plans, our 2013 equity incentive plan, as amended and restated, and our 2001 employee stock purchase plan, as 
amended. Our 1995, 1999 and 2003 stock option plans and our 2004, 2006 and 2009 long-term equity compensation plans 
have terminated and no more options, restricted shares, restricted share units or stock bonus awards may be granted under 
those plans. Pursuant to our 2013 equity incentive plan, incentive options may be granted to employees (including officers) 
and nonqualified options may be granted to employees, officers, directors, agents and consultants with exercise prices at least
equal to the fair market value of the underlying common stock at the time of grant. While our Board of Directors may grant 
options with varying vesting periods under these plans, most options granted to employees vest over four years, with 25% of 
the options vesting after one year and the remaining options vesting monthly over the next three years, and most option grants 
to non-employee directors vesting immediately. Also pursuant to our 2013 equity incentive plan, our Board of Directors may 
grant restricted stock awards, stock bonus awards, stock appreciation rights, restricted stock units, performance shares and 
performance units to employees, directors, consultants, independent contractors and advisors. As of December 31, 2016, 

21

 
   
under our 2013 equity incentive plan, an aggregate of 3,600,599 shares were available for grant as stock options or stock 
appreciation rights and an aggregate of 2,322,967 shares were available for restricted stock awards, stock bonus awards, 
restricted stock units, performance shares or performance units to employees, directors, consultants, independent contractors 
and advisors. 

(2) The  shareholders  did  not  approve  our  2000  non-executive  employee  stock  option  plan.  Under  the  2000 non-executive 
employee  stock option  plan approved by our  Board  of Directors  on  March 30,  2000, an  aggregate  of 1,500,000 shares 
pursuant to non-qualified options could be issued to employees, agents and consultants but not to officers or directors. 
Otherwise, our 2000 non-executive employee stock option plan is similar to the stock option plans described in footnote 
(1) above. On March 30, 2010, our 2000 non-executive employee stock option plan was terminated, which ended future 
grants but did not affect then outstanding options. As of December 31, 2016, under our 2000 non-executive employee stock 
plan, we had options for 33,124 shares outstanding. 

Unregistered Sales of Securities 

We had no unregistered sales of our securities in 2016 not previously reported. 

Issuer Repurchases 

We did not repurchase any of our common stock in 2016, other than in connection with the forfeiture of common stock by 
holders of restricted stock and restricted stock units in exchange for payments by the Company of statutory tax withholding amounts 
on behalf of the holders arising as a result of the vesting of restricted stock and restricted stock units.

Forward-Looking Statements 

The information set forth in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” below 
includes “forward-looking statements” as described in the section “Forward-Looking Statements” preceding Part I of this annual 
report on Form 10-K, and is subject to the safe harbor created by Section 27A of the Securities Act and Section 21E of the Exchange
Act.  Our  actual  results  could  differ  materially  from  those  anticipated  in  these  forward-looking  statements  for  many  reasons, 
including the risks faced by us and described in Item 1A. Risk Factors in Part I and other sections of this annual report on Form 10-
K and our other filings with the Securities and Exchange Commission. The following discussion should also be read in conjunction
with the Consolidated Financial Statements and accompanying Notes thereto. 

Overview and Executive Summary 

We design, develop, manufacture, market and service the high-end of the HPC market, primarily categories of systems 
commonly known as supercomputers and provide data analytics, artificial intelligence and storage solutions leveraging more than
four decades of delivering the world’s most advanced compute systems. We also provide software, system maintenance and support 
services  and  engineering  services  related  to  supercomputer  systems  and  our  data  analytics,  artificial  intelligence  and  storage 
solutions. Our customers include domestic and foreign government and government-funded entities, academic institutions and 
commercial entities. Our key target markets are the supercomputing portion of the HPC market and the expanding big data markets.
We provide customer-focused solutions based on three main models: (1) tightly integrated supercomputing and/or storage solutions,
complete with highly tuned software, that stress capability, scalability, sustained performance and reliability at scale; (2) flexible 
commodity-based “cluster” supercomputing and storage solutions based upon utilizing best-of-breed components and working with 
our customers to define solutions that meet specific needs; and (3) integrated solutions that combine industry standard tools for 
large-scale analytics and artificial intelligence applications, as well as innovative graph analysis tools, and specialized computing 
platforms. All of our solutions also emphasize total cost of ownership, scalable price-performance and data center flexibility as key 
features. Our continuing strategy is to gain market share in the supercomputer market segment, extend our technology leadership and 
differentiation, maintain our focus on execution and profitability and grow by continuing to expand our share and addressable 
market in areas where we can leverage our experience and technology, such as in high performance storage systems and powerful 
analytic tools for large volumes of data, popularly referred to as “big data.” We also meet diverse customer requirements by 
combining supercomputing, cluster supercomputing, and big data described above, into unique solutions offerings that work in a 
workflow-driven datacenter environment. 

Summary of 2016 Results 

Total revenue decreased by $94.9 million in 2016 compared to 2015, from $724.7 million to $629.8 million. Product revenue 
decreased by $101.9 million and service revenue increased by $7.0 million over the same period. The year over year decrease in 
product revenue was primarily driven by a slowdown in the HPC market that resulted in fewer opportunities in our traditional 
markets. In addition, the year over year comparison was impacted by two large systems that were accepted in the first quarter of
2015, accounting for approximately $40.0 million in revenue, for which we had previously anticipated acceptance to occur in the
fourth quarter of 2014. The year over year increase in service revenue was primarily driven by increased maintenance revenue which 
benefited from a larger installed system base as a result of product revenue growth in recent years. 

Product gross profit margin increased from 29% in 2015 to 34% in 2016. The year over year increase in product gross margin 
percentage was driven by lower memory costs, partially offset by concessions and penalties and an increase in write-offs for excess 
and obsolete inventory. Gross profit margin from services decreased from 42% in 2015 to 40% in 2016 primarily due to $3.0 million
of costs incurred to replace a high-value third-party component in a customer system that is under a service contract, higher 
headcount and compensation expense, and higher third-party costs. These amounts were partially offset by a decrease in incentive
compensation expense. 

We recorded income from operations of $9.1 million in 2016 compared to income from operations of $41.0 million in 2015. 
The decrease in income from operations was primarily attributable to lower revenue, mostly offset by an improved gross margin 
percentage,  and  a  $26.4  million  increase  in  operating  expenses  resulting  primarily  from  increased  spending  on  research  and 
development. 

Net income decreased from $27.5 million in 2015 to $10.6 million in 2016, primarily driven by the decrease in operating 

income discussed above, partially offset by a $15.9 million decrease in income tax expense. 

Net cash used in operations during 2016 was $52.3 million, as compared to net cash provided by operations of $147.8 million 
in 2015. Net cash used in operations during 2016 was primarily driven by a $78.4 million increase in our accounts receivable 

25

balance from December 31, 2015 to December 31, 2016. Cash receipts generally lag customer acceptances and we anticipate 
significant cash receipts in the first quarter of 2017 for a number of large customer acceptances in the fourth quarter of 2016.
Working capital decreased by $23.0 million from $415.2 million at December 31, 2015 to $392.1 million at December 31, 2016.

cloud computing as a solution for loosely-coupled HPC applications; and 

significant variability in market demand from quarter-to-quarter and year-to-year. 

Several of these trends have resulted in the expansion and acceptance of loosely-coupled cluster systems using processors 
manufactured by Intel, AMD and others combined with commercially available, commodity networking and other components, 
particularly in the middle and lower segments of the HPC market. These systems may offer higher theoretical peak performance for
equivalent cost, and “price/peak performance” is sometimes the dominant factor in HPC procurements. Vendors of such systems 
often put pricing pressure on us, resulting in lower margins in competitive procurements. 

In the market for the largest, and most scalable systems, those often costing in excess of $3 million, the use of generally 
available network components can result in increasing data transfer bottlenecks as these components do not balance processor power 
with  network  communication  and  system  software  capability.  With  increasing  processor  core  counts  due  to  new  many-core 
processors, these unbalanced systems will typically have lower productivity, especially in larger systems running more complex 
applications. We and others augment standard microprocessors with other processor types, such as graphics processing units and 
many-core attached processors, in order to increase computational power, further complicating programming models. In addition, 
with increasing scale, bandwidth and processor core counts, large computer systems use progressively higher amounts of power to
operate and require special cooling capabilities. 

To  position  ourselves  to  meet  the  market’s  demanding  needs,  we  concentrate  our  research  and  development  efforts  on 
technologies that enable our supercomputers to perform at scale - that is, to continue to increase actual performance as systems grow 
ever larger in size - and in areas where we can leverage our core expertise in other markets whose applications demand these tightly 
coupled architectures. We also have demonstrated expertise in system software and several processor technologies. We expect to be
in a comparatively advantageous position as larger many-core processors become available and as multiple processing technologies
become integrated into single systems in heterogeneous environments. In addition, we have continued to expand our addressable 
market by leveraging our technologies, customer base, the Cray brand and by introducing complementary products and services to 
new and existing customers, as demonstrated by our emphasis on strategic initiatives, such as “big data” analytics,  artificial
intelligence and storage and data management. 

In analytics, we are developing and delivering high performance data discovery and advanced analytics solutions. These 
solutions compete with open source software, running on commodity cluster systems. Although these competitive systems have low 
acquisition costs, the total cost of ownership, or TCO, is driven up by management, power and efficiency challenges. We concentrate
our efforts on developing solutions that minimize the TCO, delivering faster time-to-solution and advanced capabilities that are key 

26

drivers for many of our data analytics customers. We support open source technologies such as Hadoop and Spark to design large-
scale data analytics stacks that simplify analyses of scientific and commercial applications. 

In storage, we are developing and delivering high value products for the high performance storage market. Our storage 
products are primarily positioned to enable tight integration of storage to computing solutions and/or utilize parallel file processing 
technologies and facilitate storage across multiple data tiers. We support open source parallel file systems and protocols such as 
Lustre and we are a founding member of the OpenSFS (Open Scalable File System) consortia for Lustre. 

We have also expanded our addressable market by providing cluster systems and solutions to the supercomputing market that 
allow us to offer flexible platforms to incorporate best of breed components to allow customers to optimize the system to fit their 
unique requirements. 

Key Performance Indicators 

Our management monitors and analyzes several key performance indicators in order to manage our business and evaluate our 

financial and operating performance, including: 

Revenue.    Product revenue generally constitutes the major portion of our revenue in any reporting period and, for the reasons 
discussed in this annual report on Form 10-K, is subject to significant variability from period to period. In the short term, we closely 
review the status of customer proposals, customer contracts, product shipments, installations and acceptances in order to forecast
revenue and cash receipts. In the longer-term, we monitor the status of the pipeline of product sales opportunities and product
development cycles. We believe product revenue growth measured over several quarters is a better indicator of whether we are 
achieving our objective of increased market share in the supercomputing market. We have seen a decrease in the high-end of the 
supercomputing market in 2016 as compared to the last few years. The Cray XC and Cray CS products, along with our longer-term 
product roadmap are efforts to increase product revenue. We have been increasing our business and product development efforts in
big data analytics, artificial intelligence and storage and data management. We have also been increasing the size of our sales force. 
Service revenue related to our maintenance offerings is subject to less variations in the short term and may assist, in part, to offset 
the impact that the variability in product revenue has on total revenue.

Gross profit margin.    Gross profit margin is impacted by revenue and our cost to build and deliver our products and services. 
Our services tend to carry higher gross profit margins than our products. We monitor the cost of components, manufacturing, and
installation of our products. In assessing our service gross profit margin, we monitor headcount levels and third-party costs.

Operating expenses.    Our operating expenses are driven primarily by headcount and compensation expense, contracted third-
party research and development services, and incentive compensation expense. As part of our ongoing expense management efforts,
we continue to monitor headcount levels in specific geographic and operational areas.

Liquidity and cash flows.   Due to the variability in product revenue, new contracts, acceptance and payment terms, our cash 
position also varies significantly from quarter-to-quarter and within a quarter. We monitor our expected cash levels, particularly in 
light  of  increased  inventory  purchases  for  large  system  installations  and  the  risk  of  delays  in  product  shipments,  customer 
acceptances and, in the long-term, product development. Cash receipts generally lag customer acceptances.

Product revenue for 2016 decreased by $101.9 million, or 17%, over 2015, primarily driven by a slowdown in the HPC market 
that resulted fewer contract opportunities in our traditional markets. In addition, the year over year comparison was impacted by two 
large systems that were accepted in the first quarter of 2015, accounting for approximately $40.0 million in revenue, for which we 
had previously anticipated acceptance to occur in the fourth quarter of 2014. 

Product revenue for 2015 increased by $140.5 million, or 31%, over 2014 due to customer acceptances of large Cray systems 
in Saudi Arabia, South Korea, and the United States, as well as several significant sales to commercial customers in 2015. In 
addition, in the first quarter of 2015, we had customer acceptances of two large systems, accounting for approximately $40.0 million 
in revenue, for which we had previously anticipated acceptance to occur in the fourth quarter of 2014. 

Service Revenue 

Service revenue for 2016 increased by $7.0 million from 2015, or 6%. The year over year increase in service revenue was 
primarily driven by increased maintenance revenue which benefited from a larger installed system base as a result of product 
revenue growth in recent years. 

Service revenue for 2015 increased by $22.5 million from 2014, or 22%. The year over year increase in service revenue was 
driven  by  significant  increases  in  both  engineering  services,  as  a  result  of  milestone  completions  on  certain  projects,  and 
maintenance revenue, which benefited from a larger installed system base as a result of product revenue growth in recent years.

Cost of Product Revenue and Product Gross Profit 

Cost of product revenue for 2016 decreased by $94.8 million compared to 2015, driven primarily by lower product revenue 
and an improved product gross margin percentage. Product gross profit percentage was 34% in 2016 and 29% in 2015. The year 
over year increase in product gross margin percentage was driven by lower memory costs, partially offset by concessions and 
penalties and an increase in write-offs for excess and obsolete inventory. 

Cost of product revenue for 2015 increased by $105.3 million compared to 2014, driven by higher product revenue. Product 
gross profit percentage was 29% in 2015 and 30% in 2014. The product gross profit margin for 2015 was lower than it has been in
recent years and was impacted by higher costs on a few large contracts that were not anticipated at the time of bidding, driven both 
by economic factors and technical issues. 

Cost of Service Revenue and Service Gross Profit 

Cost of service revenue increased by $5.4 million in 2016 compared to 2015, driven by a larger installed base of systems 
which also resulted in higher service revenue, and $3.0 million of costs incurred to replace a high-value third-party component in a 

28

customer system that is under a service contract. Service gross profit margin decreased by two percentage points to 40% in 2016
compared to 2015. The service gross profit margin decreased primarily due to $3.0 million of costs incurred to replace a high-value
third-party component described previously, higher headcount and compensation expense, and higher third-party costs. These 
amounts were partially offset by a decrease in incentive compensation expense. 

Cost of service revenue increased by $16.5 million in 2015 compared to 2014, driven primarily by a larger installed base of 
systems which also resulted in higher service revenue. Service gross profit margin decreased by three percentage points to 42% in 
2015 compared to 2014. The service gross profit margin decreased primarily due to higher headcount and compensation expense, 
including  significantly  higher  incentive  compensation  expense,  higher  third-party  costs,  as  well  as  lower  margins  on  certain 
engineering services contracts due to a high percentage of sub-contractor costs in those contracts.

Gross research and development expenses in the table above reflect all research and development expenditures. Research and 
development expenses include personnel expenses, depreciation, allocations for certain overhead expenses, software, prototype 
materials and third-party contractor engineering expenses. 

In 2016, gross research and development expenses increased by $3.9 million from 2015 levels primarily due to increased 
investments in the development of new products. Total compensation costs increased by $1.7 million compared to 2015, driven by 
higher average headcount, partially offset by lower incentive compensation expense. Expenses for outside services increased by $1.3 
million over the same period. Net research and development expenses increased by $15.6 million compared to 2015 as a result of the 
increase in gross research and development expenses described above and a decrease in amounts included in cost of revenue and 
reimbursed research and development.  The decrease in reimbursements was primarily driven by lower funding in 2016 compared to 
2015 and the timing of milestone and project completions. 

In 2015, gross research and development expenses increased by $21.3 million from 2014 levels primarily due to increased 
investments in the development of new products and higher costs related to our engineering services contracts, which include pass-
through costs to third parties. Total compensation costs for research and development increased by $17.4 million compared to 2014. 
We increased our average headcount which resulted in higher base salaries of $8.8 million.  The higher total compensation costs also 
included the impact of an increase of $5.2 million in incentive compensation expense as well as an increase of $1.0 million in share-
based compensation expense. Net research and development expenses increased by only $2.5 million in 2015 compared to 2014 
despite such a large increase in gross research and development expenses. This was a result of an increase in amounts included in 
cost of revenue and higher reimbursed research and development, driven by higher funding in 2015 compared to 2014 and the 
timing of milestone and project completions.

Sales and Marketing.    Sales and marketing expense increased by $4.7 million in 2016 compared to 2015.  Total compensation 
costs  for  2016  increased  by  $3.6  million  compared  to  2015,  driven  by  higher  headcount,  partially  offset  by  lower  incentive 
compensation expense. Marketing program spending also increased by $0.8 million over the same period.

The $2.4 million increase in sales and marketing expense in 2015 compared to 2014 was primarily due to increased incentive 

compensation expense. 

General and Administrative.    General and administrative expense increased by $6.1 million in 2016 compared to 2015 
primarily due to a $6.0 million increase in litigation costs associated with our ongoing litigation with Raytheon, which is described 
in Note 12 - Commitments and Contingencies in the Notes to Consolidated Financial Statements in Item 15. Exhibits and Financial 
Statement Schedules in Part IV of this annual report on Form 10-K. We also incurred a $2.3 million lease termination fee for our St. 
Paul facility. These amounts were partially offset by a $2.1 million decrease in incentive compensation expense. Due to our ongoing 
litigation with Raytheon, we expect legal expenses to remain at above historical levels through at least the first quarter of 2017.

The $4.6 million increase in general and administrative expense in 2015 compared to 2014 was primarily due to increased 
headcount, increased incentive compensation expense and increased outside services. Average headcount increased to support the 
growth in the business and resulted in an increase in base salaries of $0.8 million. Incentive compensation expense increased by $1.5 
million and outside services increased by $1.9 million compared to the prior year. 

Other Income (Expense), Net 

We recorded $1.4 million and $9,000 of net other expense for the years ended December 31, 2016 and 2014, respectively, and 
$0.4 million of net other income for the year ended December 31, 2015. Net other income and expense includes gains and losses 
from foreign currency transactions, investments and disposals of assets.

Year Ended December 31, 

The difference between the income tax benefit at the federal statutory rate of 35% and our income tax expense at the effective 
rate of (7)% for the year ended December 31, 2016 was the result of research and development tax credits and additional tax 
deductions from share-based payments, sometimes referred to as excess tax benefits, partially offset by state taxes, non-deductible 
expenses and other permanent items. Excess tax benefits arise when tax deductions that we recognize with respect to share-based
compensation exceed the compensation cost attributable to share-based compensation that was recognized in our consolidated 
financial statements. The difference between the income tax provision at the federal statutory rate of 35% and our income tax 
expense at the effective income tax rate of 36% for the year ended December 31, 2015 was the result of state taxes, non-deductible 
expenses and other permanent items, partially offset by research and development tax credits. The difference between the income tax 
provision  at  the  federal  statutory  rate  of  35%  and  our  income  tax  benefit  at  the  effective  rate  of  (543)%  for  the  year  ended 
December 31, 2014 was attributable to our decision to reduce substantially all of the remaining valuation allowance that was held 
against our U.S. deferred tax assets. 

During the year ended December 31, 2014, we reduced the valuation allowance held against our U.S. deferred tax assets by 
$55.7 million based upon an assessment of all positive and negative evidence relating to future years. We consider our actual results 
over several years to have stronger weight than other more subjective indicators, including forecasts, when considering whether or 
not to establish or reduce a valuation allowance on deferred tax assets and believe that our ability to forecast results significantly into 
the future is limited due to the rapid rate of technological and competitive change in the industry in which we operate. As of 
December 31, 2014 we had generated U.S. pre-tax income in each of the last three years and cumulative U.S. pre-tax income of 
$184.8 million ($51.1 million excluding the impact of the sale of our interconnect hardware development program) over the last 
three years. In addition to our cumulative income position, the assessment of our ability to utilize our U.S. deferred tax assets
included an assessment of forecasted domestic and international earnings over a number of years, which included the impact of 
several major contracts that were finalized during the fourth quarter of 2014. 

Our conclusion about the realizability of our deferred tax assets, and therefore the appropriateness of the valuation allowance,
is reviewed quarterly and could change in future periods depending on our future assessment of all available evidence in support of 
the likelihood of realization of our deferred tax assets. If our conclusion about the realizability of our deferred tax assets and
therefore the appropriateness of our valuation allowance changes in a future period, we could record a substantial tax provision or 
benefit in our Consolidated Statements of Operations when that occurs. 

As of December 31, 2016, we had U.S. federal net operating loss carryforwards of approximately $90.2 million and U.S. 
federal  research  and  development  tax  credit  carryforwards  of  approximately  $25.2  million.  The  federal  net  operating  loss 
carryforwards will expire between 2019 through 2036, and the research and development tax credits will expire from 2021 through
2036 if not utilized. 

New Accounting Pronouncements 

In  May  2014,  the  Financial Accounting  Standards  Board,  or  FASB,  issued Accounting  Standards  Update  No.  2014-09, 
Revenue from Contracts with Customers: Topic 606, or ASU 2014-09, to supersede nearly all existing revenue recognition guidance
under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to 
customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09
defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required 
within the revenue recognition process than required under existing GAAP, including identifying performance obligations in the 
contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to 
each separate performance obligation. Adoption of ASU 2014-09 was initially required for fiscal and interim reporting periods 
beginning after December 15, 2016 using either of two methods: (i) retrospective to each prior reporting period presented with the 
option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially 

31

 
applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 
2014-09. 

In August 2015, FASB issued Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers - Deferral 
of the Effective Date: Topic 606, or ASU 2015-14, that deferred the effective date of ASU 2014-09 by one year. Application of the 
new revenue standard is permitted for fiscal and interim reporting periods beginning after December 15, 2016 and required for fiscal
and interim reporting periods beginning after December 15, 2017. We are currently evaluating the impact of the adoption of ASU 
2014-09. We will be required to make additional disclosures under the new guidance. However, at this time, we do not expect 
adoption of ASU 2014-09 to have a material impact on our consolidated financial statements. 

In July 2015, FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory: Topic 330, 
or ASU 2015-11, to amend Topic 330, Inventory. Topic 330 currently requires an entity to measure inventory at the lower of cost or 
market. Market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. 
ASU 2015-11 requires that inventory measured using either the first-in, first-out, or FIFO, or average cost method be measured at 
the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less 
reasonably predictable costs of completion, disposal and transportation. We will adopt ASU 2015-11 as required in our 2017 interim 
and annual reporting periods. We do not expect the adoption of ASU 2015-11 to have a material impact on our consolidated financial
statements. 

In November 2015, FASB issued Accounting Standards Update No. 2015-17, Balance Sheet Classification of Deferred Taxes: 
Topic 740, or ASU 2015-17. Current GAAP requires the deferred taxes for each jurisdiction to be presented as a net current asset or 
liability and net noncurrent asset or liability. This requires a jurisdiction-by-jurisdiction analysis based on the classification of the 
assets and liabilities to which the underlying temporary differences relate, or, in the case of loss or credit carryforwards, based on the 
period in which the attribute is expected to be realized. Any valuation allowance is then required to be allocated on a pro rata basis, 
by jurisdiction, between current and noncurrent deferred tax assets. The new guidance requires that all deferred tax assets and
liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. As a result, each jurisdiction 
will now only have one net noncurrent deferred tax asset or liability. The guidance does not change the existing requirement that
only permits offsetting within a jurisdiction. Adoption of ASU 2015-17 is required for fiscal reporting periods beginning after
December 15, 2016, including interim reporting periods within those fiscal years, and either prospective or retrospective application 
is permitted. Early adoption of ASU 2015-17 is permitted. At the time of adoption, all of our deferred tax assets and liabilities, along 
with any related valuation allowance, will be classified as noncurrent on our Consolidated Balance Sheet.  We will adopt ASU 2015-
17 in our 2017 interim and annual reporting periods. 

In January 2016, FASB issued Accounting Standards Update No. 2016-01, Recognition and Measurement of Financial Assets 
and  Financial  Liabilities:  Topic  825,  or  ASU  2016-01.    The  updated  guidance  enhances  the  reporting  model  for  financial 
instruments, which includes amendments to address aspects of recognition, measurement, presentation and disclosure. Adoption of
ASU 2016-01 is required for fiscal reporting periods beginning after December 15, 2017, including interim reporting periods within 
those  fiscal  years.  We  do  not  expect  the  adoption  of ASU  2016-01  to  have  a  material  impact  on  our  consolidated  financial 
statements. 

In February 2016, FASB issued Accounting Standards Update No. 2016-02, Leases: Topic 842, or ASU 2016-02, that replaces 
existing lease guidance. The new standard is intended to provide enhanced transparency and comparability by requiring lessees to
record right-of-use assets and corresponding lease liabilities on the balance sheet. Under the new guidance, leases will continue to be 
classified  as  either  finance  or  operating,  with  classification  affecting  the  pattern  of  expense  recognition  in  the  Consolidated
Statements of Operations. Lessor accounting is largely unchanged under ASU 2016-02. Adoption of ASU 2016-02 is required for 
fiscal reporting periods beginning after December 15, 2018, including interim reporting periods within those fiscal years with early 
adoption being permitted. The new standard is required to be applied with a modified retrospective approach to each prior reporting 
period presented with various optional practical expedients. We are currently evaluating the potential impact of the pending adoption 
of ASU 2016-02 on our consolidated financial statements. 

In March 2016, FASB issued Accounting Standards Update No. 2016-09, Compensation-Stock Compensation (Topic 718): 
Improvements to Employee Share-Based Payment Accounting, or ASU 2016-09. The updated guidance simplifies and changes how 
companies  account  for  certain  aspects  of  share-based  payment  awards  to  employees,  including  accounting  for  income  taxes, 
forfeitures, and statutory tax withholding requirements, as well as classification of certain items in the statement of cash flows. 
Adoption of ASU 2016-09 is required for fiscal reporting periods beginning after December 15, 2016, including interim reporting
periods within those fiscal years with early adoption being permitted. We early-adopted ASU 2016-09 at the beginning of the first
quarter of 2016. 

32

At the time of adoption of ASU 2016-09, we recognized $16.6 million in deferred tax assets for all excess tax benefits that had
not been previously recognized because the related tax deduction had not reduced taxes payable. This was accomplished through a
cumulative-effect adjustment to accumulated deficit. All excess tax benefits and all tax deficiencies generated in the current and 
future periods will be recorded as income tax benefit or expense in our Consolidated Statements of Operations in the reporting 
period in which they occur. This will result in increased volatility in our effective tax rate. We have determined that none of the other 
provisions of ASU 2016-09 will have a significant impact on our consolidated financial statements. 

In August 2016, FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230): Classification 
of Certain Cash Receipts and Cash Payments, or ASU 2016-15. The updated guidance clarifies how companies present and classify 
certain cash receipts and cash payments in the statement of cash flows. Adoption of ASU 2016-15 is required for fiscal reporting
periods beginning after December 15, 2017, including interim reporting periods within those fiscal years with early adoption being 
permitted. We do not expect the adoption of ASU 2016-15 to have a material impact on our consolidated financial statements. 

In November 2016, FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted 
Cash, or ASU 2016-18, which amends ASC 230 to add or clarify guidance on the classification and presentation of restricted cash in 
the statement of cash flows. The amended guidance requires that amounts that are deemed to be restricted cash and restricted cash
equivalents be included in the cash and cash-equivalent balances in the statement of cash flows. A reconciliation between the 
statement of financial position and the statement of cash flows must be disclosed when the statement of financial position includes 
more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. The guidance also requires that 
changes in restricted cash and restricted cash equivalents that result from transfers between cash, cash equivalents, and restricted
cash and restricted cash equivalents should not be presented as cash flow activities in the statement of cash flows. An entity with a 
material balance of amounts generally described as restricted cash and restricted cash equivalents must disclose information about 
the nature of the restrictions.  Adoption of ASU 2016-18 is required for fiscal reporting periods beginning after December 15, 2017, 
including interim reporting periods within those fiscal years with early adoption being permitted. We do not expect the adoption of 
ASU 2016-18 to have a material impact on our consolidated financial statements. 

In January 2017, FASB issued Accounting Standards Update No. 2017-04, Intangibles - Goodwill and Other (Topic 350): 
Simplifying the Test for Goodwill Impairment, or ASU 2017-04, which eliminates Step 2 from the goodwill impairment test. ASU 
2017-04 also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative
assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to 
perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Adoption of ASU 
2017-04 is required for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019 with early
adoption being permitted for annual or interim goodwill impairment tests performed on testing dates after January 1, 2017. We do
not expect the adoption of ASU 2017-04 to have a material impact on our consolidated financial statements. 

Liquidity and Capital Resources 

We generate cash from operations predominantly from the sale of supercomputing systems and related services. We typically 
have a small number of significant contracts that make up the majority of total revenue. We have also entered into a sales-type lease 
agreement with a customer, under which we will receive quarterly payments over the term of the lease, which expires in September
2020.  Material  changes  in  certain  of  our  balance  sheet  accounts  were  due  to  the  timing  of  product  deliveries  and  customer 
acceptances, contractually determined billings, timing and level of inventory purchased for future deliveries, timing and level of 
incentive compensation and cash collections. Working capital requirements, including inventory purchases and normal capital 
expenditures, are generally funded with cash from operations. 

We previously contemplated expanding our manufacturing capabilities in Chippewa Falls, Wisconsin in order to increase our 
manufacturing capacity. This project, which we estimated would require total capital expenditures in the range of $25.0 million, is 
currently suspended. The decision of when and whether to undertake this project in the future will be dependent on our expectations 
of future needs. 

Total cash and investments decreased from $284.9 million at December 31, 2015 to $224.6 million at December 31, 2016, 
primarily  driven by  the  timing of  collections  from  customers. As  of December 31, 2016, $14.3  million of our  total cash  and 
investments balance was held by foreign subsidiaries. As of December 31, 2016, we had $1.7 million in restricted cash associated
with certain letters of credit outstanding to secure customer prepayments. As of December 31, 2016, we had working capital of 
$392.1 million compared to $415.2 million as of December 31, 2015.

Operating Activities.    For the year ended December 31, 2016, cash used in operating activities was primarily driven by a 
$78.4 million increase in our accounts receivable balance from December 31, 2015 to December 31, 2016. Cash receipts generally 
lag customer acceptances and, because we had a number of large customer acceptances in the fourth quarter of 2016, we anticipate
significant cash receipts in the first quarter of 2017. For the year ended December 31, 2015, cash provided by operating activities
was primarily driven by net income of $27.5 million and the positive impact of adding back non-cash operating items of $42.4 
million,  customer  acceptances  of  our  systems  that  resulted  in  a  decrease  of  $21.3  million  in  inventory,  and  collections  from 
customers that resulted in a decrease of $36.7 million in accounts and other receivables. 

Investing Activities.    For the year ended December 31, 2016, cash provided by investing activities was principally due to sales 
and maturities of debt securities of $31.0 million, partially offset by purchases of debt securities of $16.2 million and purchases of 
property  and  equipment  of  $7.5  million.  For  the  year  ended  December 31,  2015,  cash  provided  by  investing  activities  was 
principally due to sales and maturities of debt securities of $16.2 million and a release of $13.4 million in restricted cash related to a 
prepayment on a system from a customer that was released at the time of delivery, partially offset by purchases of debt securities of 
$15.0 million and purchases of property and equipment of $7.5 million.

Financing Activities.    Net cash used in financing activities in 2016, 2015 and 2014 resulted primarily from statutory tax 
withholding amounts made in exchange for the forfeiture of common stock by holders of vesting restricted stock, partially offset by 
cash received from the issuance of common stock from the exercise of options and from the issuance of stock through our employee
stock purchase plan.

Over the next twelve months, we expect our significant cash requirements will relate to operational expenses. Operational 
expenses consist primarily of personnel costs, costs of inventory associated with certain large-scale product deliveries, spare parts, 
outside engineering expenses, and the acquisition of property and equipment. In addition, we lease certain equipment and facilities
used in our operations under operating leases in the normal course of business.

Amounts Committed by Year 

In  the  second  quarter  of  2016,  we  entered  into  a  new  operating  lease  for  facilities  in  Bloomington,  Minnesota  that  will 
principally be staffed with teams from software development, sales and service. This new lease will replace our existing lease in St. 
Paul, Minnesota. The new lease is for a minimum period of eight years beginning in May 2017. Minimum contractual obligations 
under the new lease total $32.6 million. We paid an early termination fee of approximately $2.3 million to terminate our existing 
lease in St. Paul, Minnesota which was recorded as an operating expense in 2016. We received a one-time lease incentive payment
of $2.3 million as part of our new lease agreement to cover the termination fee, which will be amortized over the term of the new
lease. We anticipate that 2017 spending on leasehold improvements for the new facilities will be approximately $5.5 million. 

As of December 31, 2016, we had a $50.0 million revolving line of credit, or Credit Facility, with Wells Fargo Bank, National 
Association, designed to be used for general corporate purposes, including working capital requirements and capital expenditures.  
The Credit Facility also supports the issuance of letters of credit. The Credit Facility is secured by a first priority lien in all of our 
accounts receivable and other rights to payment, general intangibles, inventory and equipment. 

Any borrowings under the Credit Facility bear interest at either a fluctuating rate equal to the daily one month LIBOR rate plus
a margin of 1.25% or a fixed interest rate for one, three or six months equal to the LIBOR rate for the applicable period plus a
margin of 1.25%.  We are also required to pay the lender customary letter of credit fees, and a commitment fee of 0.18% per annum 

34

in respect of the unutilized commitment amount under the Credit Facility. The Credit Facility requires that we maintain certain
financial ratios and restricts our ability to incur additional indebtedness, pay dividends or distributions, create liens on assets, and 
engage in certain other activities. We were in compliance with all of our financial covenants as of the end of each quarter for the year 
ended December 31, 2016. The Credit Facility matures in December 2017. 

We made no draws and had no outstanding cash borrowings on the line of credit as of December 31, 2016. 

As of December 31, 2016, we had $3.3 million in USD equivalent value in outstanding letters of credit and $1.7 million in 

restricted cash associated with certain letters of credit to secure customer prepayments and other customer related obligations.

In our normal course of operations, we have development arrangements under which we engage outside engineering resources 
to work on our research and development projects. For the year ended December 31, 2016, we incurred $15.6 million for such 
arrangements. 

At any particular time, our cash position is affected by the timing of cash receipts for product sales, maintenance contracts, 
government co-funding for research and development activities and our payments for inventory, resulting in significant fluctuations 
in our cash balance from quarter-to-quarter and within a quarter. Our principal sources of liquidity are our cash and cash equivalents, 
short-term investments and cash from operations. We expect our cash resources to be adequate for at least the next twelve months.

Beyond the next twelve months, the adequacy of our cash resources will largely depend on our success in achieving profitable 

operations and positive operating cash flows on a sustained basis. 

Critical Accounting Policies and Estimates 

This discussion, as well as disclosures included elsewhere in this annual report on Form 10-K, is based upon our financial 
statements, which have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires 
us  to  make  estimates  and  judgments  that affect  the  reported  amounts  of  assets,  liabilities,  revenue  and  expenses,  and related 
disclosure of contingencies. In preparing our financial statements in accordance with GAAP, there are certain accounting policies 
that are particularly important. These include revenue recognition, inventory valuation, accounting for income taxes, research and
development expenses and share-based compensation. We believe these accounting policies and others set forth in Note 2 — 
Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in Item 15. Exhibits and Financial 
Statement Schedules in Part IV of this annual report on Form 10-K should be reviewed as they are integral to understanding our 
results of operations and financial condition. In some cases, these policies represent required accounting. In other cases, they may 
represent a choice between acceptable accounting methods or may require substantial judgment or estimation. 

Additionally, we consider certain judgments and estimates to be significant, including those relating to the estimated selling 
price determination used in revenue recognition, percentage of completion accounting, estimates of proportional performance on co-
funded engineering contracts, collectibility of receivables, determination of inventory at the lower of cost or market, the value of 
used equipment returned or to be returned associated with customer contracts, useful lives for depreciation and amortization, 
determination of future cash flows associated with impairment testing of long-lived assets, including goodwill and other intangibles, 
determination of the implicit interest rate used in the sales-type lease calculation, estimated warranty liabilities, determination of the 
fair value of stock options and other assessments of fair value, evaluation of the probability of vesting of performance-based 
restricted  stock  and  restricted  stock  units,  calculation  of  deferred  income  tax  assets,  including  estimates  of  future  financial
performance in the determination of the likely recovery of deferred income tax assets, our ability to utilize such assets, potential 
income  tax  assessments,  the  outcome  of  any  legal  proceedings  and  other  contingencies. We  base  our  estimates  on  historical 
experience, current conditions and on other assumptions that we believe to be reasonable under the circumstances. Actual results
may differ materially from these estimates and assumptions. 

Our management has discussed the selection of significant accounting policies and the effect of judgments and estimates with 

the Audit Committee of our Board of Directors. 

Revenue Recognition 

We recognize revenue, including transactions under sales-type leases, when it is realized or realizable and earned. We 
consider revenue realized or realizable and earned when we have persuasive evidence of an arrangement, delivery has occurred, the
sales price is fixed or determinable, and collectibility is reasonably assured. Delivery does not occur until the products have been 
shipped or services provided to the customer, the risk of loss has transferred to the customer, and, where applicable, a customer
acceptance has been obtained. The sales price is not considered to be fixed or determinable until all material contingencies related to 
the sales have been resolved. We record revenue in the Consolidated Statements of Operations net of any sales, use, value added or 
certain excise taxes imposed by governmental authorities on specific sales transactions. In addition to the aforementioned general 

35

policy, the following are our statements of policy with regard to multiple-element arrangements and specific revenue recognition
policies for each major category of revenue.

Multiple-Element Arrangements. We commonly enter into revenue arrangements that include multiple deliverables of our 
product and service offerings due to the needs of our customers. Products may be delivered in phases over time periods which can be 
as long as five years. Maintenance services generally begin upon acceptance of the first equipment delivery and future deliveries of 
equipment generally have an associated maintenance period. We consider the maintenance period to commence upon acceptance of 
the product, or installation of the product where a formal acceptance is not required, which may include a warranty period and 
accordingly allocate a portion of the arrangement consideration as a separate deliverable which is recognized as service revenue over 
the entire service period. Other services such as training and engineering services can be delivered as a discrete delivery or over the 
term of the contract. A multiple-element arrangement is separated into more than one unit of accounting if the following criteria are 
met:

•

•

The delivered item(s) has value to the customer on a standalone basis; and 

If the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the 
undelivered item(s) is considered probable and substantially in our control. 

If these criteria are met for each element, the arrangement consideration is allocated to the separate units of accounting based
on each unit’s relative selling price. If these criteria are not met, the arrangement is accounted for as one unit of accounting which 
would result in revenue being recognized ratably over the contract term or being deferred until the earlier of when such criteria are 
met or when the last undelivered element is delivered. 

We follow a selling price hierarchy in determining the best estimate of the selling price of each deliverable. Certain products
and services are sold separately in standalone arrangements for which we are sometimes able to determine vendor specific objective 
evidence, or VSOE. We determine VSOE based on normal pricing and discounting practices for the product or service when sold 
separately. 

When we are not able to establish VSOE for all deliverables in an arrangement with multiple elements, we attempt to establish 
the selling price of each remaining element based on third-party evidence, or TPE. Our inability to establish VSOE is often due to a 
relatively small sample of customer contracts that differ in system size and contract terms which can be due to infrequently selling 
each element separately, not pricing products within a narrow range, or only having a limited sales history, such as in the case of 
certain advanced and emerging technologies. TPE is determined based on our prices or competitor prices for similar deliverables
when sold separately. However, we are often unable to determine TPE, as our offerings usually contain a significant level of 
customization and differentiation from those of competitors and we are often unable to reliably determine what similar competitor
products’ selling prices are on a standalone basis. 

When we are unable to establish selling price using VSOE or TPE, we use estimated selling price, or ESP, in our allocation of 
arrangement consideration. The objective of ESP is to determine the price at which we would transact a sale if the product or service 
were sold on a standalone basis. In determining ESP, we use  the cost to provide the product or service plus a margin, or consider
other factors. When using cost plus a margin, we consider the total cost of the product or service, including customer-specific and 
geographic factors. We also consider the historical margins of the product or service on previous contracts and several factors
including any changes to pricing methodologies, competitiveness of products and services and cost drivers that would cause future
margins to differ from historical margins. 

Products. We most often recognize revenue from sales of products upon delivery or customer acceptance of the system. Where 
formal acceptance is not required, we recognize revenue upon delivery or installation. When the product is part of a multiple element 
arrangement, we allocate a portion of the arrangement consideration to product revenue based on estimates of selling price.

Services. Maintenance services are provided under separate maintenance contracts with customers. These contracts generally 
provide for maintenance services for one year, although some are for multi-year periods, often with prepayments for the term of the 
contract. We consider the maintenance period to commence upon acceptance of the product or installation in situations where a 
formal acceptance is not required, which may include a warranty period. When service is part of a multiple element arrangement, we 
allocate a portion of the arrangement consideration to maintenance service revenue based on estimates of selling price. Maintenance 
contracts that are billed in advance of revenue recognition are recorded as deferred revenue. Maintenance revenue is recognized
ratably over the term of the maintenance contract.

Revenue from engineering services is recognized as services are performed. 

Project Revenue. Revenue from design and build contracts is recognized under the percentage-of-completion, or POC method. 
Under the POC method, revenue is recognized based on the costs incurred to date as a percentage of the total estimated costs to

36

fulfill  the  contract.  If  circumstances  arise  that  change  the  original  estimates  of  revenues,  costs,  or  extent  of  progress  toward
completion, revisions to the estimates are made. These revisions may result in increases or decreases in estimated revenues or costs, 
and such revisions are recorded in income in the period in which the circumstances that gave rise to the revision become known by 
management. We perform ongoing profitability analyses of our contracts accounted for under the POC method in order to determine
whether the latest estimates of revenue, costs and extent of progress require updating. If at any time these estimates indicate that the 
contract will be unprofitable, the entire estimated loss for the remainder of the contract is recorded immediately.

We record revenue from certain research and development contracts which include milestones using the milestone method if 
the milestones are determined to be substantive. A milestone is considered to be substantive if management believes there is 
substantive uncertainty that it will be achieved and the milestone consideration meets all of the following criteria: 

•

It is commensurate with either of the following: 

•

•

Our performance to achieve the milestone; or 

The enhancement of value of the delivered item or items as a result of a specific outcome resulting from our 
performance to achieve the milestone. 

•

•

It relates solely to past performance. 

It is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) 
within the arrangement. 

The individual milestones are determined to be substantive or non-substantive in their entirety and milestone consideration is 

not bifurcated. 

Revenue from projects is classified as Product Revenue or Service Revenue, based on the nature of the work performed. 

Nonmonetary Transactions. We value and record nonmonetary transactions at the fair value of the asset surrendered unless the 

fair value of the asset received is more clearly evident, in which case the fair value of the asset received is used.

Inventory Valuation 

We record our inventory at the lower of cost or market. We regularly evaluate the technological usefulness and anticipated 
future demand for our inventory components. Due to rapid changes in technology and the increasing demands of our customers, we 
are continually developing new products. Additionally, during periods of product or inventory component upgrades or transitions,
we may acquire significant quantities of inventory to support estimated current and future production and service requirements. As a 
result, it is possible that older inventory items we have purchased may become obsolete, be sold below cost or be deemed in excess 
of quantities required for production or service requirements. When we determine it is not likely we will recover the cost of 
inventory items through future sales, we write-down the related inventory to our estimate of its market value. 

Because the products we sell have high average sales prices and because a high number of our prospective customers receive 
funding from U.S. or foreign governments, it is difficult to estimate future sales of our products and the timing of such sales. It also 
is difficult to determine whether the cost of our inventories will ultimately be recovered through future sales. While we believe our 
inventory is stated at the lower of cost or market and that our estimates and assumptions to determine any adjustments to the cost of 
our inventories are reasonable, our estimates may prove to be inaccurate. We have sold inventory previously reduced in part or in 
whole to zero, and we may have future sales of previously written-down inventory. We also may incur additional expenses to write-
down inventory to its estimated market value. Adjustments to these estimates in the future may materially impact our operating 
results. 

Accounting for Income Taxes 

Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and
liabilities and operating loss and tax credit carryforwards and are measured using the enacted tax rates and laws that will be in effect 
when the differences and carryforwards are expected to be recovered or settled. A valuation allowance for deferred tax assets is
provided when we estimate that it is more likely than not that all or a portion of the deferred tax assets will not be realized through 
future operations. This assessment is based upon consideration of available positive and negative evidence, which includes, among 
other things, our recent results of operations and expected future profitability. We consider our actual historical results over several 
years to have stronger weight than other more subjective indicators, including forecasts, when considering whether to establish or 
reduce a valuation allowance on deferred tax assets. We have significant difficulty projecting future results due to the nature of the 
business and the industry in which we operate. 

37

Our  deferred  tax  assets  increased  by  $16.6  million  as  a  result  of  the  adoption  of ASU  2016-09,  Compensation-Stock 
Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, or ASU 2016-09. No changes were 
required to previously recorded valuation allowances at the time of adoption.  ASU 2016-09 will result in increased volatility in our 
effective tax rate. 

As of December 31, 2016, we had approximately $94.3 million of net deferred tax assets before application of a valuation 
allowance. As of December 31, 2016, net deferred tax assets after reduction by the valuation allowance of $8.7 million were $85.6 
million. During the year ended December 31, 2014, we reduced substantially all of the remaining valuation allowance held against
our U.S. deferred tax assets. The assessment of our ability to utilize our deferred tax assets included an assessment of all known 
business risks and industry trends as well as forecasted domestic and international earnings over a number of years. Our ability to 
forecast results significantly into the future is limited due to the rapid rate of technological and competitive change in the industry in 
which we operate. 

We continue to provide a valuation allowance against specific U.S. deferred tax assets and a full valuation allowance against 
deferred tax assets arising in a limited number of foreign jurisdictions as the realization of such assets is not considered to be more 
likely than not at this time. In a future period our assessment of the realizability of our deferred tax assets and therefore the
appropriateness of the valuation allowance could change based on an assessment of all available evidence, both positive and 
negative in that future period. If our conclusion about the realizability of our deferred tax assets and therefore the appropriateness of 
the valuation allowance changes in a future period we could record a substantial tax provision or benefit in our Consolidated 
Statements of Operations when that occurs. We recognize the income tax benefit from a tax position only if it is more likely than not 
that the tax position will be sustained on examination by the applicable taxing authorities, based on the technical merits of our 
position. The tax benefit recognized in the financial statements from such a position is measured based on the largest benefit that has 
a greater than fifty percent likelihood of being realized upon ultimate settlement. 

Estimated interest and penalties are recorded as a component of interest expense and other expense, respectively. 

Research and Development Expenses 

Research and development expenses include costs incurred in the development and production of our hardware and software, 
costs incurred to enhance and support existing product features, costs incurred to support and improve our development processes,
and costs related to future product development. Research and development costs are expensed as incurred, and may be offset by co-
funding from third parties. We may also enter into arrangements whereby we make advance, non-refundable payments to a vendor to
perform certain research and development services. These payments are deferred and recognized over the vendor’s estimated 
performance period. 

Amounts to be received under co-funding arrangements with the U.S. government or other customers are based on either 
contractual milestones or costs incurred. These co-funding milestone payments are recognized in operations as performance is 
estimated to be completed and are measured as milestone achievements occur or as costs are incurred. These estimates are reviewed
on a periodic basis and are subject to change, including in the near term. If an estimate is changed, net research and development 
expense could be impacted significantly. 

We do not record a receivable from the U.S. government prior to completing the requirements necessary to bill for a milestone 
or cost reimbursement. Funding from the U.S. government is subject to certain budget restrictions and milestones may be subject to 
completion risk, and as a result, there may be periods in which research and development costs are expensed as incurred for which 
no reimbursement is recorded, as milestones have not been completed or the U.S. government has not funded an agreement. 
Accordingly, there can be substantial variability in the amount of net research and development expenses from quarter to quarter and 
year to year. 

We classify amounts to be received from funded research and development projects as either revenue or a reduction to 
research and development expense based on the specific facts and circumstances of the contractual arrangement, considering total
costs expected to be incurred compared to total expected funding and the nature of the research and development contractual 
arrangement. In the event that a particular arrangement is determined to represent revenue, the corresponding costs are classified as 
cost of revenue. 

Share-based Compensation 

We measure compensation cost for share-based payment awards at fair value and recognize it as compensation expense over 
the service period for awards expected to vest. We recognize share-based compensation expense for all share-based payment awards,
net of an estimated forfeiture rate. We recognize compensation cost for only those shares expected to vest on a straight-line basis 
over the requisite service period of the award. 

38

Determining the appropriate fair value model and calculating the fair value of share-based payment awards requires subjective 
assumptions, including the expected life of the share-based payment awards and stock price volatility. We utilize the Black-Scholes 
options pricing model to value the stock options granted under our options plans. In this model, we utilize assumptions related to 
stock price volatility, stock option term and forfeiture rates that are based upon both historical factors as well as management’s 
judgment. 

The fair value of restricted stock and restricted stock units is determined based on the number of shares or units granted and 

the quoted price of our common stock at the date of grant. 

We grant performance vesting restricted stock and performance vesting restricted stock units to executives as one of the ways 
to align compensation with shareholder interests. Vesting of these awards is contingent upon achievement of certain performance
conditions. Compensation expense for these awards is only recognized when vesting is deemed to be “probable”. Awards are 
evaluated for probability of vesting during each reporting period. 

39

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

We are exposed to financial market risks, including changes in interest rates and equity price fluctuations. 

Interest Rate Risk:    We invest our available cash in money market mutual funds whose underlying investments include 
investment-grade debt instruments of corporate issuers and in debt instruments of the U.S. government and its agencies. We do not 
have any derivative instruments or auction rate securities in our investment portfolio. We protect and preserve invested funds by 
limiting default, market and reinvestment risk. Investments in both fixed-rate and floating-rate interest earning instruments carry a 
degree of interest rate risks. Fixed-rate securities may have their fair market value adversely affected due to a rise in interest rates, 
while floating-rate securities may produce less income than expected if interest rates fall. Due in part to these factors, our future 
investment income may fall short of expectations due to changes in interest rates or we may suffer losses in principal if forced to sell 
securities which have declined in market value due to changes in interest rates. Although we are subject to the above noted risks, we 
believe that a 0.5% change in interest rates would not be material.

Foreign Currency Risk:    We sell our products primarily in North America, Asia and Europe. As a result, our financial results 
could be affected by factors such as changes in foreign currency exchange rates or weak economic conditions in foreign markets.
Our products are generally priced based on U.S. dollars, and a strengthening of the U.S. dollar could make our products less 
competitive in foreign markets. While we often sell products with payments in U.S. dollars, our product sales contracts may call for 
payment in foreign currencies and to the extent we do so, or engage with our foreign subsidiaries in transactions deemed to be either 
short-term or long-term in nature, we are subject to foreign currency exchange risks.

As of December 31, 2016, we had entered into foreign currency exchange contracts that were designated as cash flow hedges 
that hedge approximately $46.9 million of anticipated cash receipts on specific foreign currency denominated sales contracts. These 
foreign currency exchange contracts hedge the risk of foreign exchange rate changes between the time that the related contracts were 
signed and when the cash receipts are expected to be received. As of December 31, 2016, we had entered into foreign currency 
exchange contracts that had been dedesignated for the purposes of hedge accounting treatment totaling $107.5 million. Unrealized
gains or losses recorded in the Consolidated Statements of Operations related to these contracts are generally offset by foreign
currency adjustments on related receivables. These foreign currency exchange contracts are considered to be economic hedges. 

Our foreign maintenance contracts are typically paid in local currencies and provide a partial natural hedge against foreign 
exchange exposure. To the extent that we wish to repatriate any of these funds to the United States, however, we are subject to
foreign  exchange  risks.  We  do  not  hold  or  purchase  any  currency  forward  exchange  contracts  for  trading  purposes.  As  of 
December 31, 2016, a hypothetical 10% unfavorable change in foreign currency exchange rates would impact our annual operating 
results and cash flows by approximately $0.2 million.

Item 9A.    Controls and Procedures

Disclosure Controls and Procedures 

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our 
reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules 
and forms, and that such information is accumulated and communicated to management, as appropriate, to allow timely decisions 
regarding required disclosure. Our management, with the participation and under the supervision of our Chief Executive Officer,
Chief Financial Officer and Chief Accounting Officer/Corporate Controller, evaluated the effectiveness of our disclosure controls
and procedures as of the end of the period covered by this report, and based on that evaluation, our Chief Executive Officer and
Chief Financial Officer determined that our disclosure controls and procedures were effective. 

Changes in Internal Control over Financial Reporting 

There have been no changes in our internal controls over financial reporting during the fourth quarter of 2016 that have 

materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. 

Management’s Report on Internal Control Over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined 
by Rule 13a-15(f) under the Exchange Act. Internal control over financial reporting is a process designed to provide reasonable
assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in
accordance with accounting principles generally accepted in the United States of America. 

Our 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 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 accounting 
principles generally accepted in the United States of America, and that our receipts and expenditures are being made only in 
accordance with authorizations 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,  including  our  Chief  Executive  Officer  and  Chief  Financial  Officer,  conducted  an  evaluation  of  the 
effectiveness of our internal control over financial reporting based on the framework in “Internal Control — Integrated Framework 
(2013)”  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.  Based  on  this  evaluation,  our 
management concluded that our internal control over financial reporting was effective as of December 31, 2016. 

Peterson  Sullivan  LLP,  an  independent  registered  public  accounting  firm,  has  expressed  an  unqualified  opinion  on  the 

effectiveness of our internal control over financial reporting as of December 31, 2016.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Shareholders 
Cray Inc. 

We have audited Cray Inc. and Subsidiaries’ (“the Company”) internal control over financial reporting as of December 31, 2016, 
based  on  criteria  established  in  Internal  Control  -  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring 
Organizations of the Treadway Commission (“COSO”).  The Company’s management is responsible for maintaining effective 
internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting 
included in the accompanying Management’s Report on Internal Control Over Financial Reporting.  Our responsibility is to express
an opinion on the Company’s internal control over financial reporting based on our audit. 

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

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

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

In  our  opinion,  the  Company  maintained,  in  all  material  respects,  effective  internal  control  over  financial  reporting  as  of 
December 31, 2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
consolidated  balance  sheets  of  the  Company  as  of  December  31,  2016  and  2015,  and  the  related  consolidated  statements  of 
operations,  comprehensive  income,  shareholders’  equity,  and cash flows  for  each of  the  years  in  the  three-year period  ended 
December 31, 2016, and our report dated February 10, 2017, expressed an unqualified opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

NOTE 1    DESCRIPTION OF BUSINESS 

Cray  Inc.,  or  Cray,  or  the  Company,  designs,  develops,  manufactures,  markets  and  services  the  high-end  of  the  high 
performance computing, or HPC, market, primarily categories of systems commonly known as supercomputers, and provides data 
analytics, artificial intelligence and storage solutions. The Company also provides software, system maintenance and support 
services and engineering services related to supercomputer systems and data analytics, artificial intelligence and storage solutions. 
Cray’s supercomputer systems address challenging scientific, engineering, commercial and national security computing problems. 
The Company’s customers include foreign and domestic governments and government-funded entities, academic institutions and 
commercial entities. 

NOTE 2    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Accounting Principles 

The  consolidated  financial  statements  and  accompanying  notes  are  prepared  in  accordance  with  accounting  principles 

generally accepted in the United States of America, or GAAP. 

Principles of Consolidation 

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All material 

intercompany balances and transactions have been eliminated. 

Reclassifications 

Certain prior year amounts have been reclassified to conform with the current year presentation. There has been no impact on 

previously reported net income or shareholders’ equity from such reclassifications. 

Use of Estimates 

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions 
that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Actual results could
differ materially from those estimates. 

Cash, Cash Equivalents and Restricted Cash 

Cash and cash equivalents consist of highly liquid financial instruments that are readily convertible to cash and have maturities
of  three  months  or  less  at  the  time  of  acquisition. The  Company  maintains  cash  and  cash  equivalent  balances  with  financial 
institutions that exceed federally insured limits. As of December 31, 2015, the Company had $1.7 million in short-term restricted
cash. As of December 31, 2016 and 2015, the Company had $1.7 million in long-term restricted cash.  The restricted cash is 
associated with certain letters of credit outstanding to secure customer prepayments. 

Investments 

The Company’s investments consist primarily of commercial paper, corporate debt, and other debt securities. Debt securities 
are classified as available-for-sale and are reported at fair value with unrealized gains and losses, net of applicable taxes, recorded in 
accumulated other comprehensive income, a component of shareholders’ equity. The realized gains and losses for available-for-sale
securities are included in other income and expense in the Consolidated Statements of Operations. Realized gains and losses are
calculated based on the specific identification method. 

The Company monitors its investment portfolio for impairment on a periodic basis. When the carrying value of an investment 
in debt securities exceeds its fair value and the decline in value is determined to be an other-than-temporary decline, and when the 
Company does not intend to sell the debt security and it is not more likely than not that the Company will be required to sell the debt 
securities prior to recovery of its amortized cost basis, the Company records an impairment charge in the amount of the credit loss 
and the balance, if any, to other comprehensive income (loss). 

Investments that mature between three months and one year from the purchase date are initially classified as short-term 
investments in the Consolidated Balance Sheet. Investments that mature beyond one year from the purchase date are initially 
classified as long-term investments in the Consolidated Balance Sheet.  

F-6

CRAY INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) 

Foreign Currency Derivatives 

The Company uses foreign currency exchange contracts to hedge certain foreign currency exposures. Foreign currency 
exchange contracts are cash flow hedges of the Company’s foreign currency exposures on certain revenue contracts and are recorded
at the contract’s fair value. Most of the Company’s foreign currency exchange contracts are designated as cash flow hedges for the 
purposes of hedge accounting treatment and any gains or losses on the effective portion of the foreign currency exchange contract is 
initially reported in “Accumulated other comprehensive income,” a component of shareholders’ equity, with a corresponding asset or 
liability recorded based on the fair value of the foreign currency exchange contract. When the hedged transaction is recognized, any 
unrecognized gains or losses on the hedged transaction are reclassified into results of operations in the same period. Any hedge
ineffectiveness is recorded to operations in the current period. The Company measures hedge effectiveness by comparing changes in 
fair values of the foreign currency exchange contract and expected cash flows based on changes in the spot prices of the underlying 
currencies. Cash flows from foreign currency exchange contracts accounted for as cash flow hedges are classified in the same 
category as the cash flows from the items being hedged. Unrealized gains or losses related to foreign currency exchange contracts
that are not designated as cash flow hedges for the purposes of hedge accounting treatment are recorded in other income (expense) in 
the Consolidated Statements of Operations and are generally offset by foreign currency adjustments on related receivables. The 
Company does not use derivative financial instruments for speculative purposes. 

Concentration of Credit Risk 

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash
and cash equivalents, available-for-sale investments, accounts receivable, short-term and long-term restricted cash and foreign
currency exchange contracts. 

The Company maintains cash and cash equivalents, available-for-sale securities and foreign currency exchange contracts with 
various financial institutions. As part of its risk management process, the Company performs periodic evaluations of the relative
credit standing of the financial institutions. The Company has not sustained any credit losses from instruments held at financial
institutions. The Company utilizes foreign currency exchange contracts to protect against the effects of foreign currency fluctuations. 
Such contracts involve the risk of non-performance by the counterparty, which could result in a material loss. 

The  Company  currently  derives  a  significant  portion  of  its  revenue  from  sales  of  products  and  services  to  the 
U.S. Government. See Note 17 — Segment Information for additional information. Given the type of customers, the Company does 
not believe its accounts receivable represent significant credit risk. 

The  Company  currently  has a  long-term  investment  in  a sales-type  lease  it  entered  into with one of its  customers. See 
Note 7 — Sales-type Lease for additional information. Given the credit standing of the customer, the Company does not believe that 
this investment represents a significant credit risk. 

Other Concentration 

The Company obtains certain components from single-source suppliers due to technology, availability, price, quality or other 
considerations. The loss of a single-source supplier, the single-source supplier’s inability to deliver the required components or 
intellectual property due to natural disaster or other reasons, the deterioration of the relationship with a single-source supplier, or any 
unilateral modification of contract terms under which the Company is supplied components by a single-source supplier could have a 
significant adverse effect on the Company’s revenue and gross margins. 

Accounts Receivable 

Accounts receivable are stated at principal amounts and are primarily comprised of amounts contractually due from customers 
for products and services and amounts due from government research and development contracts. The Company provides an 
allowance for doubtful accounts based on an evaluation of customer past due account balances. In determining whether to record an
allowance for a specific customer, the Company considers a number of factors, including prior payment history and financial 
information for the customer. 

Fair Values of Financial Instruments

The Company measures certain financial assets and liabilities at fair value based on the exchange price that would be received 
for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an 
orderly transaction between market participants. The Company’s financial instruments primarily consist of debt securities, time

F-7

CRAY INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) 

deposits, money market funds, and foreign currency derivatives. See Note 3 — Fair Value Measurement for a further discussion on 
fair value of financial instruments. 

Inventories 

Inventories are valued at the lower of cost or market, with cost computed on a first-in, first-out basis (FIFO). The Company 
regularly evaluates the technological usefulness and anticipated future demand for various inventory components and the expected
use of the inventory. When the Company determines it is not likely the cost of inventory items will be recovered through future
sales, the Company writes-down the related inventory to its estimated market value. 

In connection with certain of its sales agreements, the Company may receive used equipment from a customer. This inventory 
generally will be recorded at no value based on the expectation that the Company will not be able to resell or otherwise use the
equipment. In the event that the Company has a specific contractual plan for resale at the date the inventory is acquired, the 
inventory is recorded at its estimated fair value. 

Property and Equipment and Intangible Assets, Net 

Property and equipment are recorded at cost less accumulated depreciation and amortization. Additions and improvements are 
capitalized and maintenance and repairs are expensed as incurred. Depreciation is calculated on a straight-line basis over the 
estimated useful lives of the related assets, ranging from eighteen months to seven years for furniture and fixtures, three years for 
computer equipment, and eight to twenty-five years for buildings and land improvements. Leasehold improvements are depreciated 
over the life of the lease or asset, whichever is shorter. 

The Company amortizes purchased intangible assets with finite lives using the straight-line method over the estimated economic 

lives of the assets, ranging from two to ten years. 

Service Spares 

Service spares are valued at the lower of cost or market and represent inventory used to support service and maintenance 
agreements with customers. As inventory is utilized, replaced items are returned to the Company and are either repaired or scrapped. 
Costs incurred to repair inventory to a usable state are charged to expense as incurred. Service spares are recorded at cost and
amortized over the estimated service life of the related product platform (generally four years). 

Impairment of Long-Lived Assets and Intangibles 

The Company evaluates property, plant and equipment and intangible assets with finite lives for impairment whenever events 
or changes in circumstances indicate the carrying value of an asset may not be recoverable. The Company assesses the recoverability
of the assets based on the undiscounted future cash flow the assets are expected to generate and recognizes an impairment loss when 
estimated undiscounted future cash flow expected to result from the use of the asset plus net proceeds expected from disposition of 
the asset, if any, are less than the carrying value of the asset. When the Company identifies an impairment, the carrying value of the 
asset  is  reduced  to  its  estimated  fair  value  based  on  a  discounted  cash  flow  approach  or,  when  available  and  appropriate,  to 
comparable market values. 

Goodwill 

Goodwill is not amortized but is tested for impairment at least annually. The Company reviews goodwill for impairment 
annually at the beginning of its fourth fiscal quarter and whenever events or changes in circumstances indicate the carrying value of 
the asset may not be recoverable. The goodwill impairment test consists of a two-step process, if necessary. However, the Company 
first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its 
carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in
ASC Topic 350. The more likely than not threshold is defined as having a likelihood of more than 50 percent. If, after assessing the 
totality of events or circumstances, the Company determines that it is not more likely than not that the fair value of a reporting unit is 
less  than  its  carrying  amount,  then performing  the  two-step  impairment  test  is  unnecessary  and  goodwill  is  considered  to  be 
unimpaired. However, if based on the qualitative assessment the Company concludes that it is more likely than not that the fair value 
of a reporting unit is less than its carrying amount, the Company will proceed with performing the two-step process. 

In step one, the Company determines the fair value of each reporting unit and compares it to its carrying value. If the fair value
of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and no further testing 
is performed. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then the 

F-8

 
 
CRAY INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) 

Company must perform the second step of the impairment test in order to determine the implied fair value of the reporting unit’s
goodwill. If the carrying value of a reporting unit’s goodwill exceeds its implied fair value, the Company records an impairment loss 
equal to the difference. 

The Company performed its qualitative assessment during the fourth fiscal quarter of 2016 and concluded that it was more 
likely than not that the fair values of its reporting units were greater than their carrying amounts. After reaching this conclusion, the 
two-step impairment test was unnecessary and no further testing was performed. The qualitative factors that were considered 
included, but were not limited to, general economic conditions, outlook for the HPC and big data markets, recent and forecasted
financial performance and the price of the Company’s common stock.  

Business Combinations 

The Company accounts for business combinations using the acquisition method of accounting and allocates the purchase price 
to the tangible and intangible assets acquired and the liabilities assumed based upon their estimated fair values at the acquisition 
date. The difference between the purchase price and the fair value of the net assets acquired is recorded as goodwill. The Company
uses estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date. During the 
measurement period, which may be up to one year from the acquisition date, any refinements made to the fair value of the assets and 
liabilities assumed are recorded with retrospective effect. 

The fair values of intangible assets acquired are estimated using a discounted cash flow approach with Level 3 inputs. Under 
this method, an intangible asset’s fair value is equal to the present value of the incremental after-tax cash flows (excess earnings) 
attributable solely to the intangible asset over its remaining useful life. To calculate fair value, the Company uses risk-adjusted cash 
flows discounted at rates considered appropriate given the inherent risks associated with each type of asset. The Company believes 
the level and timing of cash flows appropriately reflects market participant assumptions. 

Revenue Recognition 

The Company recognizes revenue, including transactions under sales-type leases, when it is realized or realizable and earned. 
The Company considers revenue realized or realizable and earned when it has persuasive evidence of an arrangement, delivery has
occurred, the sales price is fixed or determinable, and collectibility is reasonably assured. Delivery does not occur until the products 
have been shipped or services provided to the customer, risk of loss has transferred to the customer, and, where applicable, a 
customer acceptance has been obtained. The sales price is not considered to be fixed or determinable until all material contingencies 
related to the sales have been resolved. The Company records revenue in the Consolidated Statements of Operations net of any sales,
use, value added or certain excise taxes imposed by governmental authorities on specific sales transactions. In addition to the
aforementioned general policy, the following are the Company’s statements of policy with regard to multiple-element arrangements
and specific revenue recognition policies for each major category of revenue. 

Multiple-Element Arrangements. The Company commonly enters into revenue arrangements that include multiple deliverables 
of its product and service offerings due to the needs of its customers. Products may be delivered in phases over time periods which 
can be as long as five years. Maintenance services generally begin upon acceptance of the first equipment delivery and future 
deliveries of equipment generally have an associated maintenance period. The Company considers the maintenance period to 
commence upon acceptance of the product or installation in situations where a formal acceptance is not required, which may include 
a warranty period and accordingly allocates a portion of the arrangement consideration as a separate deliverable which is recognized
as service revenue over the entire service period. Other services such as training and engineering services can be delivered as a 
discrete delivery or over the term of the contract. A multiple-element arrangement is separated into more than one unit of accounting 
if the following criteria are met:

•

•

The delivered item(s) has value to the customer on a standalone basis; and 

If the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the 
undelivered item(s) is considered probable and substantially in the control of the Company. 

If these criteria are met for each element, the arrangement consideration is allocated to the separate units of accounting based
on each unit’s relative selling price. If these criteria are not met, the arrangement is accounted for as one unit of accounting which 
would result in revenue being recognized ratably over the contract term or being deferred until the earlier of when such criteria are 
met or when the last undelivered element is delivered.

CRAY INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) 

The Company follows a selling price hierarchy in determining the best estimate of the selling price of each deliverable. 
Certain products and services are sold separately in standalone arrangements for which the Company is sometimes able to determine
vendor specific objective evidence, or VSOE. The Company determines VSOE based on normal pricing and discounting practices 
for the product or service when sold separately. 

When the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements, the Company 
attempts to establish the selling price of each remaining element based on third-party evidence, or TPE. The Company’s inability to 
establish VSOE is often due to a relatively small sample of customer contracts that differ in system size and contract terms which 
can be due to infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales 
history, such as in the case of certain advanced and emerging technologies. TPE is determined based on the Company’s prices or 
competitor prices for similar deliverables when sold separately. However, the Company is often unable to determine TPE, as the 
Company’s offerings usually contain a significant level of customization and differentiation from those of competitors and the 
Company is often unable to reliably determine what similar competitor products’ selling prices are on a standalone basis. 

When the Company is unable to establish selling price using VSOE or TPE, the Company uses estimated selling price, or ESP, 
in its allocation of arrangement consideration. The objective of ESP is to determine the price at which the Company would transact a 
sale if the product or service were sold on a standalone basis. In determining ESP, the Company uses the cost to provide the product 
or service plus a margin, or considers other factors. When using cost plus a margin, the Company considers the total cost of the
product or service, including customer-specific and geographic factors. The Company also considers the historical margins of the
product or service on previous contracts and several factors including any changes to pricing methodologies, competitiveness of
products and services and cost drivers that would cause future margins to differ from historical margins. 

Products. The Company most often recognizes revenue from sales of products upon customer acceptance of the system. 
Where formal acceptance is not required, the Company recognizes revenue upon delivery or installation. When the product is part of 
a multiple element arrangement, the Company allocates a portion of the arrangement consideration to product revenue based on 
estimates of selling price.

Services. Maintenance services are provided under separate maintenance contracts with customers. These contracts generally 
provide for maintenance services for one year, although some are for multi-year periods, often with prepayments for the term of the 
contract. The Company considers the maintenance period to commence upon acceptance of the product, or installation of the product
where a formal acceptance is not required, which may include a warranty period. When service is part of a multiple element 
arrangement, the Company allocates a portion of the arrangement consideration to maintenance service revenue based on estimates
of  selling  price.  Maintenance  contracts  that  are  billed  in  advance  of  revenue  recognition  are  recorded  as  deferred  revenue. 
Maintenance revenue is recognized ratably over the term of the maintenance contract.

Revenue from engineering services is recognized as services are performed. 

Project Revenue. Revenue from design and build contracts is recognized under the percentage-of-completion, or POC, method. 
Under the POC method, revenue is recognized based on the costs incurred to date as a percentage of the total estimated costs to
fulfill  the  contract.  If  circumstances  arise  that  change  the  original  estimates  of  revenues,  costs,  or  extent  of  progress  toward
completion, revisions to the estimates are made. These revisions may result in increases or decreases in estimated revenues or costs, 
and such revisions are recorded in income in the period in which the circumstances that gave rise to the revision become known by 
management. The Company performs ongoing profitability analyses of its contracts accounted for under the POC method in order to
determine whether the latest estimates of revenue, costs and extent of progress require updating. If at any time these estimates
indicate that the contract will be unprofitable, the entire estimated loss for the remainder of the contract is recorded immediately.

The Company records revenue from certain research and development contracts which include milestones using the milestone 
method if the milestones are determined to be substantive. A milestone is considered to be substantive if management believes there 
is substantive uncertainty that it will be achieved and the milestone consideration meets all of the following criteria: 

•

It is commensurate with either of the following: 

•

•

The Company’s performance to achieve the milestone; or 

The enhancement of value of the delivered item or items as a result of a specific outcome resulting from 
the Company’s performance to achieve the milestone. 

•

It relates solely to past performance. 

F-10 

CRAY INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) 

•

It is reasonable relative to all of the deliverables and payment terms (including other potential milestone consideration) 
within the arrangement. 

The individual milestones are determined to be substantive or non-substantive in their entirety and milestone consideration is 

not bifurcated. 

Revenue from projects is classified as Product Revenue or Service Revenue, based on the nature of the work performed. 

Nonmonetary  Transactions. The  Company  values  and  records  nonmonetary  transactions  at  the  fair  value  of  the  asset 
surrendered unless the fair value of the asset received is more clearly evident, in which case the fair value of the asset received is 
used.

Sales-type leases 

When the Company leases a system to a customer, the accounting involves specific determinations, which often involve 
complex  provisions  and  significant  judgments.  The  four  criteria  of  the  accounting  standard  that  the  Company  uses  in  the 
determination of whether a lease is a sales-type lease or an operating lease are: (a) a review of the lease term to determine if it is 
equal to or greater than 75% of the economic life of the system; (b) a review of the minimum lease payments to determine if they are 
equal to or greater than 90% of the fair value of the system; (c) a determination of whether or not the lease transfers ownership to the 
lessee at the end of the lease term; and (d) a determination of whether or not the lease contains a bargain purchase option. If the lease 
transaction meets one of the four criteria, then it is recorded as a sales-type lease; otherwise it is an operating lease. Additionally, the 
Company  assesses  whether  collectibility  of  the  lease  payments  is  reasonably  assured  and  whether  there  are  any  significant 
uncertainties related to costs that it has yet to incur with respect to the lease. 

The Company considers the economic lives of most of its products to range from three to four years. There is no significant 
after-market for the Company’s used products and the Company believes that the economic lives are representative of the periods
during which its products are expected to be economically usable, with normal service, for the purposes for which they were 
intended. Residual values are not significant. 

The discount rate implicit in the sales-type lease is used to calculate the present value of minimum lease payments, which the 
Company records as a lease receivable. The minimum lease payment consists of the gross lease payments net of executory costs and
contingencies, if any. While revenue is recognized at inception of the lease, the cash flow from the sales-type lease occurs over the 
course of the lease, which results in interest income. Unearned interest income is recorded at inception of the lease and amortized
over the lease term using the effective interest method. 

Foreign Currency Translation

The Company uses the U.S. dollar predominantly as its functional currency. Assets and liabilities of foreign subsidiaries that 
have a functional currency denominated in non-U.S. dollars are translated into U.S. dollars at year-end exchange rates, and revenue 
and expenses of these foreign subsidiaries are translated at average rates prevailing during the year. Translation adjustments are
included in “Accumulated other comprehensive income,” a separate component of shareholders’ equity. Transaction gains and losses
arising from transactions denominated in a currency other than the functional currency of the entity involved are included in “Other 
income (expense), net” in the accompanying Consolidated Statements of Operations. Net transaction losses were $1.0 million for 
2016 and net transaction gains were $1.6 million and $2.1 million for 2015 and 2014, respectively. 

Research and Development 

Research and development expenses include costs incurred in the development and production of hardware and software, costs 
incurred to enhance and support existing product features, costs incurred to support and improve development processes, and costs
related to future product development. Research and development costs are expensed as incurred, and may be offset by co-funding
from third parties. The Company may also enter into arrangements whereby it makes advance, non-refundable payments to a vendor 
to perform certain research and development services. These payments are deferred and recognized over the vendor’s estimated 
performance period. 

Amounts to be received under co-funding arrangements with the U.S. government or others are based on either contractual 
milestones or costs incurred. These co-funding milestone payments are recognized in operations as performance is estimated to be
completed and are measured as milestone achievements occur or as costs are incurred. These estimates are reviewed on a periodic

F-11 

CRAY INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) 

basis and are subject to change, including in the near term. If an estimate is changed, net research and development expense could be 
impacted significantly. 

The Company does not record a receivable from the U.S. government prior to completing the requirements necessary to bill 
for a milestone or cost reimbursement. Funding from the U.S. government is subject to certain budget restrictions and milestones
may be subject to completion risk, and as a result, there may be periods in which research and development costs are expensed as
incurred for which no reimbursement is recorded, as milestones have not been completed or the U.S. government has not funded an
agreement. Accordingly, there can be substantial variability in the amount of net research and development expenses from quarter to 
quarter and year to year. 

The Company classifies amounts to be received from funded research and development projects as either revenue or a 
reduction to research and development expense based on the specific facts and circumstances of the contractual arrangement, 
considering total costs expected to be incurred compared to total expected funding and the nature of the research and development 
contractual arrangement. In the event that a particular arrangement is determined to represent revenue, the corresponding research 
and development costs are classified as cost of revenue. 

Income Taxes 

Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and
liabilities and operating loss and tax credit carryforwards and are measured using the enacted tax rates and laws that will be in effect 
when the differences and carryforwards are expected to be recovered or settled. A valuation allowance for deferred tax assets is
provided when the Company estimates that it is more likely than not that all or a portion of the deferred tax assets may not be
realized through future operations. This assessment is based upon consideration of available positive and negative evidence, which 
includes, among other things, recent results of operations and expected future profitability. The Company considers its actual 
historical  results  over  several  years  to  have  stronger  weight  than  other  more  subjective  indicators,  including  forecasts,  when 
considering whether to establish or reduce a valuation allowance on deferred tax assets. The Company has significant difficulty
projecting future results due to the nature of the business and the industry in which it operates. 

The Company’s deferred tax assets increased by $16.6 million as a result of the adoption of Accounting Standards Update No. 
2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, or ASU 
2016-09. No changes were required to previously recorded valuation allowances at the time of adoption.  ASU 2016-09 will result in 
increased volatility in the Company’s effective tax rate. 

As of December 31, 2016, the Company had approximately $94.3 million of net deferred tax assets before application of a 
valuation  allowance.  As  of  December 31,  2016,  net  deferred  tax  assets  after  reduction  by  the  valuation  allowance  of  $8.7 
million were $85.6 million. During the year ended December 31, 2014, the Company reduced substantially all of the remaining 
valuation allowance held against the Company’s U.S. deferred tax assets. The assessment of the Company’s ability to utilize its
deferred tax assets included an assessment of all known business risks and industry trends as well as forecasted domestic and 
international earnings over a number of years. The Company’s ability to forecast results significantly into the future is limited due to 
the rapid rate of technological and competitive change in the industry in which it operates. 

The Company continues to provide a valuation allowance against specific U.S. deferred tax assets and a valuation allowance 
against deferred tax assets arising in a limited number of foreign jurisdictions as the realization of such assets is not considered to be 
more likely than not at this time. In a future period, the Company’s assessment of the realizability of its deferred tax assets and 
therefore the appropriateness of the valuation allowance could change based on an assessment of all available evidence, both 
positive and negative in that future period. If the Company’s conclusion about the realizability of its deferred tax assets and therefore 
the appropriateness of the valuation allowance changes in a future period, the Company could record a substantial tax provision or 
benefit in its Consolidated Statements of Operations when that occurs. The Company recognizes the income tax benefit from a tax
position only if it is more likely than not that the tax position will be sustained on examination by the applicable taxing authorities, 
based on the technical merits of the Company’s position. The tax benefit recognized in the financial statements from such a position 
is measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. 

Estimated interest and penalties are recorded as a component of interest expense and other expense, respectively. 

F-12 

CRAY INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) 

Share-Based Compensation 

The Company measures compensation cost for share-based payment awards at fair value and recognizes it as compensation 
expense over the service period for awards expected to vest. Share-based compensation expense is recognized for all share-based
payment awards, net of an estimated forfeiture rate. Compensation cost is only recognized for those shares expected to vest on a
straight-line basis over the requisite service period of the award. 

Determining the appropriate fair value model and calculating the fair value of share-based payment awards requires subjective 
assumptions, including the expected life of the share-based payment awards and stock price volatility. The Company utilizes the
Black-Scholes options pricing model to value the stock options granted under its options plans. In this model, the assumptions 
utilized relate to stock price volatility, stock option term and forfeiture rates that are based upon both historical factors as well as 
management’s judgment. 

The fair value of restricted stock and restricted stock units is determined based on the number of shares or units granted and 

the quoted price of the Company’s common stock at the date of grant. 

The Company grants performance vesting restricted stock and performance vesting restricted stock units to executives as one 
of the ways to align compensation with shareholder interests. Vesting of these awards is contingent upon achievement of certain
performance conditions. Compensation expense for these awards is only recorded when vesting is deemed to be “probable.” 

  Awards are evaluated for probability of vesting each reporting period. 

Shipping and Handling Costs 

Costs related to shipping and handling are included in “Cost of product revenue” and “Cost of service revenue” in the 

accompanying Consolidated Statements of Operations. 

Advertising Costs 

Sales and marketing expenses in the accompanying Consolidated Statements of Operations included advertising expenses of 
$3.2 million, $2.3 million, and $2.9 million in 2016, 2015, and 2014, respectively. The Company incurs advertising costs for 
representation  at  certain  trade  shows,  promotional  events  and  sales  lead  generation,  as  well  as  design  and  printing  costs  for 
promotional materials. The Company expenses all advertising costs as incurred. 

Earnings Per Share, or EPS 

Basic  EPS  is  computed by  dividing net  income  available  to  common  shareholders by the  weighted  average number  of 
common shares, excluding unvested restricted stock outstanding during the period. Diluted EPS is computed by dividing net income
available to common shareholders by the weighted average number of common and potential common shares outstanding during the 
period,  which  includes  the  additional  dilution  related  to  conversion  of  stock  options,  unvested  restricted  stock  and  unvested 
restricted stock units as computed under the treasury stock method. 

For the years ended December 31, 2016, 2015 and 2014, the added shares from these items included in the calculation of 
diluted shares and EPS totaled approximately 1.2 million, 1.4 million, and 1.8 million, respectively. Potentially dilutive shares of 1.2 
million, 0.9 million, and 0.6 million, respectively, have been excluded from the denominator in the computation of diluted EPS for 
the years ended December 31, 2016, 2015 and 2014, respectively, because they were antidilutive. An additional 1.2 million, 1.2 
million and 0.8 million performance vesting restricted stock and performance vesting restricted stock units were excluded from the 
computation of diluted EPS for the years ended December 31, 2016, 2015 and 2014, respectively, because the conditions for vesting 
had not been met as of the balance sheet date. 

Accumulated Other Comprehensive Income 

Accumulated other comprehensive income, a component of Shareholders’ equity, consisted of the following at December 31 

(in thousands): 

Accumulated unrealized net loss on available-for-sale investments 
Accumulated currency translation adjustments 
Accumulated unrealized net gain on cash flow hedges 
Accumulated other comprehensive income

Recent Accounting Pronouncements 

In  May  2014,  the  Financial Accounting  Standards  Board,  or  FASB,  issued Accounting  Standards  Update  No.  2014-09, 
Revenue from Contracts with Customers: Topic 606, or ASU 2014-09, to supersede nearly all existing revenue recognition guidance
under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to 
customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09
defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required 
within the revenue recognition process than required under existing GAAP, including identifying performance obligations in the 
contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to 
each separate performance obligation. Adoption of ASU 2014-09 was initially required for fiscal and interim reporting periods 
beginning after December 15, 2016 using either of two methods: (i) retrospective to each prior reporting period presented with the 
option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially 
applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 
2014-09. 

In August 2015, FASB issued Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers - Deferral 
of the Effective Date: Topic 606, or ASU 2015-14, that deferred the effective date of ASU 2014-09 by one year. Application of the 
new revenue standard is permitted for fiscal and interim reporting periods beginning after December 15, 2016 and required for fiscal
and interim reporting periods beginning after December 15, 2017. The Company is currently evaluating the impact of the adoption
of ASU 2014-09. The Company will be required to make additional disclosures under the new guidance. However, at this time, the 
Company does not expect adoption of ASU 2014-09 to have a material impact on its consolidated financial statements. 

In July 2015, FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory: Topic 330, 
or ASU 2015-11. Topic 330 currently requires an entity to measure inventory at the lower of cost or market. Market could be 
replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. ASU 2015-11 requires that 
inventory measured using either the first-in-first-out (FIFO) or average cost method be measured at the lower of cost and net 
realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable 
costs of completion, disposal and transportation. The Company will adopt ASU 2015-11 as required in its 2017 interim and annual
reporting periods. The Company does not expect the adoption of ASU 2015-11 to have a material impact on its consolidated 
financial statements. 

In November 2015, FASB issued Accounting Standards Update No. 2015-17, Balance Sheet Classification of Deferred Taxes: 
Topic 740, or ASU 2015-17. Current GAAP requires the deferred taxes for each jurisdiction to be presented as a net current asset or 
liability and net noncurrent asset or liability. This requires a jurisdiction-by-jurisdiction analysis based on the classification of the 
assets and liabilities to which the underlying temporary differences relate, or, in the case of loss or credit carryforwards, based on the 
period in which the attribute is expected to be realized. Any valuation allowance is then required to be allocated on a pro rata basis, 
by jurisdiction, between current and noncurrent deferred tax assets. The new guidance requires that all deferred tax assets and
liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. As a result, each jurisdiction 
will now only have one net noncurrent deferred tax asset or liability. The guidance does not change the existing requirement that
only permits offsetting within a jurisdiction. Adoption of ASU 2015-17 is required for fiscal reporting periods beginning after
December 15, 2016, including interim reporting periods within those fiscal years, and either prospective or retrospective application 
is permitted. Early adoption of ASU 2015-17 is permitted. At the time of adoption, all of the Company’s deferred tax assets and
liabilities, along with any related valuation allowance, will be classified as noncurrent on its Consolidated Balance Sheet. The
Company will adopt ASU 2015-17 in its 2017 interim and annual reporting periods. 

In January 2016, FASB issued Accounting Standards Update No. 2016-01, Recognition and Measurement of Financial Assets 
and  Financial  Liabilities:  Topic  825,  or  ASU  2016-01.    The  updated  guidance  enhances  the  reporting  model  for  financial 
instruments, which includes amendments to address aspects of recognition, measurement, presentation and disclosure. Adoption of
ASU 2016-01 is required for fiscal reporting periods beginning after December 15, 2017, including interim reporting periods within 
those fiscal years. The Company does not expect the adoption of ASU 2016-01 to have a material impact on its consolidated 
financial statements. 

In February 2016, FASB issued Accounting Standards Update No. 2016-02, Leases: Topic 842, or ASU 2016-02, that replaces 
existing lease guidance. The new standard is intended to provide enhanced transparency and comparability by requiring lessees to
record right-of-use assets and corresponding lease liabilities on the balance sheet. Under the new guidance, leases will continue to be 

F-14 

CRAY INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) 

classified  as  either  finance  or  operating,  with  classification  affecting  the  pattern  of  expense  recognition  in  the  Consolidated
Statements of Operations. Lessor accounting is largely unchanged under ASU 2016-02. Adoption of ASU 2016-02 is required for 
fiscal reporting periods beginning after December 15, 2018, including interim reporting periods within those fiscal years with early 
adoption being permitted. The new standard is required to be applied with a modified retrospective approach to each prior reporting 
period presented with various optional practical expedients. The Company is currently evaluating the potential impact of the pending 
adoption of ASU 2016-02 on its consolidated financial statements. 

In March 2016, FASB issued Accounting Standards Update No. 2016-09, Compensation-Stock Compensation (Topic 718): 
Improvements to Employee Share-Based Payment Accounting, or ASU 2016-09. The updated guidance simplifies and changes how 
companies  account  for  certain  aspects  of  share-based  payment  awards  to  employees,  including  accounting  for  income  taxes, 
forfeitures, and statutory tax withholding requirements, as well as classification of certain items in the statement of cash flows. 
Adoption of ASU 2016-09 is required for fiscal reporting periods beginning after December 15, 2016, including interim reporting
periods within those fiscal years with early adoption being permitted. The Company early-adopted ASU 2016-09 in the first quarter
of 2016. 

At the time of adoption of ASU 2016-09, the Company recognized $16.6 million in deferred tax assets for all excess tax 
benefits  that  had  not  been  previously  recognized  because  the  related  tax  deduction  had  not  reduced  taxes  payable. This  was 
accomplished  through  a  cumulative-effect  adjustment  to  accumulated  deficit. All  excess  tax  benefits  and  all  tax  deficiencies 
generated in the current and future periods will be recorded as income tax benefit or expense in the Company’s Consolidated 
Statements of Operations in the reporting period in which they occur. This will result in increased volatility in the Company’s
effective tax rate. The Company has determined that none of the other provisions of ASU 2016-09 will have a significant impact on 
its consolidated financial statements. 

In August 2016, FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230): Classification 
of Certain Cash Receipts and Cash Payments, or ASU 2016-15. The updated guidance clarifies how companies present and classify 
certain cash receipts and cash payments in the statement of cash flows. Adoption of ASU 2016-15 is required for fiscal reporting
periods beginning after December 15, 2017, including interim reporting periods within those fiscal years with early adoption being 
permitted. The Company does not expect the adoption of ASU 2016-15 to have a material impact on its consolidated financial 
statements. 

In November 2016, FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted 
Cash, or ASU 2016-18, which amends ASC 230 to add or clarify guidance on the classification and presentation of restricted cash in 
the statement of cash flows. The amended guidance requires that amounts that are deemed to be restricted cash and restricted cash
equivalents be included in the cash and cash-equivalent balances in the statement of cash flows. A reconciliation between the 
statement of financial position and the statement of cash flows must be disclosed when the statement of financial position includes 
more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. The guidance also requires that 
changes in restricted cash and restricted cash equivalents that result from transfers between cash, cash equivalents, and restricted
cash and restricted cash equivalents should not be presented as cash flow activities in the statement of cash flows. An entity with a 
material balance of amounts generally described as restricted cash and restricted cash equivalents must disclose information about 
the nature of the restrictions.  Adoption of ASU 2016-18 is required for fiscal reporting periods beginning after December 15, 2017, 
including interim reporting periods within those fiscal years with early adoption being permitted. The Company does not expect the 
adoption of ASU 2016-18 to have a material impact on its consolidated financial statements. 

In January 2017, FASB issued Accounting Standards Update No. 2017-04, Intangibles - Goodwill and Other (Topic 350): 
Simplifying the Test for Goodwill Impairment, or ASU 2017-04, which eliminates Step 2 from the goodwill impairment test. 
ASU 2017-04  also  eliminates  the  requirements  for  any  reporting  unit  with  a  zero  or  negative  carrying  amount  to  perform  a 
qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the 
option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary.
Adoption of ASU 2017-04 is required for annual or interim goodwill impairment tests in fiscal years beginning after December 15,
2019 with early adoption being permitted for annual or interim goodwill impairment tests performed on testing dates after January 1, 
2017.  The  Company  does  not  expect  the  adoption  of ASU  2017-04  to  have  a  material  impact  on  its  consolidated  financial 
statements.

NOTE 3    FAIR VALUE MEASUREMENTS 

Under  FASB Accounting  Standards  Codification  Topic  820,  Fair  Value  Measurements  and  Disclosures,  based  on  the 
observability of the inputs used in the valuation techniques used to determine the fair value of certain financial assets and liabilities, 
the Company is required to provide the following information according to the fair value hierarchy. The fair value hierarchy ranks 
the quality and reliability of the information used to determine fair values. 

In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or 
liabilities. Fair values determined by Level 2 inputs utilize observable inputs other than Level 1 prices, such as quoted prices for 
similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by 
observable market data for substantially the full term of the related assets or liabilities. Fair values determined by Level 3 inputs are 
unobservable data points for the asset or liability, and include situations where there is little, if any, market activity for the asset or 
liability. The following table presents information about the Company’s financial assets and liabilities that have been measured at 
fair value on a recurring basis as of December 31, 2016 and 2015, and indicates the fair value hierarchy of the valuation inputs
utilized to determine such fair value (in thousands):

The foreign currency exposure related to these contracts was approximately $107.5 million as of December 31, 2016 and 
$55.6 million as of December 31, 2015. Unrealized gains or losses related to these dedesignated contracts are recorded in other
income (expense) in the Consolidated Statements of Operations and are generally offset by foreign currency adjustments on related
receivables. These foreign currency exchange contracts are considered to be economic hedges. 

Cash receipts associated with the hedged contracts are expected to be received from 2017 through 2022, during which time the 
revenue on the associated sales contracts is expected to be recognized, or in the case of receivables denominated in a foreign 
currency, the receivables balances will be collected. Any gain or loss on hedged foreign currency will be recognized at the time of 
customer acceptance, or in the case of receivables denominated in a foreign currency, each period during which hedged receivables 
denominated in a foreign currency are outstanding.

As of December 31, 2016 and 2015, the fair value of outstanding foreign currency exchange contracts totaled a net gain of 

$11.2 million and $11.6 million, respectively.

Unbilled receivables represent amounts where the Company has recognized revenue in advance of the contractual billing 

terms. Advance billings represent billings made based on contractual terms for which revenue has not been recognized. 

As of December 31, 2016 and 2015, accounts receivable included $104.6 million and $44.2 million, respectively, due from the 
U.S. Government. Of these amounts, $1.4 million and $2.2 million were unbilled as of December 31, 2016 and 2015, respectively, 
based upon contractual billing arrangements with these customers. As of December 31, 2016, two non-U.S. Government customers 
accounted  for  24%  of  total  accounts  and  other  receivables.   As  of  December 31,  2015,  one  non-U.S.  Government  customer 
accounted for 18% of total accounts and other receivables. 

NOTE 7    SALES-TYPE LEASE 

As of December 31, 2016 and 2015, the Company had a sales-type lease with one of its customers. Under the terms of the 
original  agreement,  the  Company provided  a  high  performance  computing solution  to  the  customer for  a  term  of  four  years, 
beginning  at  the  customer’s  acceptance  of  the  system.  In  the  second  quarter  of  2016,  the  Company  delivered  a  second  high 
performance computing solution and extended the original agreement, which will now end in September 2020. The lease extension, 
and delivery of the second high performance computing solution, has been accounted for as a separate sale and is not considered a 
lease modification. The lease is designated in British Pounds and the Company has entered into certain foreign currency exchange
contracts that act as an economic hedge for the foreign currency exposure associated with this arrangement.

In  its  normal  course  of  operations,  the  Company  engages  in  development  arrangements  under  which  it  hires  outside 
engineering resources to augment its existing internal staff in order to complete research and development projects, or parts thereof. 
For the years ended December 31, 2016, 2015 and 2014, the Company incurred $15.6 million, $14.3 million and $12.2 million, 
respectively, for such arrangements. 

Litigation 

From time to time, the Company is subject to various legal proceedings that arise in the ordinary course of business. Other than

as outlined below, none of these legal proceedings are deemed to be material to the Company’s business. 

The Company is subject to patent lawsuits brought by Raytheon. The first suit was brought by Raytheon on September 25, 2015 
in the Eastern District of Texas (Civil Action No. 2:15-cv-1554) asserting infringement of four patents owned by Raytheon. Two of 
the asserted patents relate to computer hardware alleged to be encompassed by Cray’s current and past products, and the two 
remaining asserted patents relate to features alleged to be performed by certain third-party software that Cray optionally includes as 
part of its product offerings.  A second suit was brought by Raytheon on April 22, 2016 in the Eastern District of Texas (Civil Action 
No. 2:16-cv-423) asserting infringement of five patents owned by Raytheon. In this second suit, all five asserted patents relate to 
features alleged to be performed by certain third-party software that Cray optionally includes as part of its product offerings. Trial in 
the first action is currently scheduled to commence in March 2017 and trial in the second action is currently scheduled to commence
in  October  2017.    The  Company  is  vigorously  defending  these  actions.  The  probable  outcome  of  either  litigation  cannot  be 
determined, nor can the Company estimate a range of potential loss. Based on its review of the matters to date, the Company 
believes that it has valid defenses and claims in each of the two lawsuits.  As a result, the Company considers the likelihood of a 
material loss related to these matters to be remote. 

NOTE 13    INCOME TAXES 

Income taxes are recognized for the amount of taxes payable for the current year and for the impact of deferred tax assets and 
liabilities, which represent consequences of events that have been recognized differently in the financial statements under GAAP
than for tax purposes. 

Most of the Company’s deferred tax assets result from net operating loss carryforwards and research and development tax 
credits. As of December 31, 2016, the Company had U.S. federal net operating loss carryforwards of approximately $90.2 million 
and U.S. federal research and development tax credit carryforwards of approximately $25.2 million. Upon the adoption of ASU 
2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting in March 
of 2016, the Company recognized $16.6 million in deferred tax benefits from approximately $47.4 million of federal net operating
losses attributable to share-based income tax deductions that exceeded amounts that had been recognized for financial reporting
purposes. These deferred tax benefits were recorded as a cumulative-effect adjustment to accumulated deficit. The federal net 
operating loss carryforwards will expire from 2019 through 2036, and the federal research and development tax credits will expire 
from 2021 through 2036 if not utilized. Utilization of $25.6 million of the Company’s federal net operating loss carryforwards 
generated  prior  to  May 10,  2001  is  limited  under  Section 382  of  the  Internal  Revenue  Code  to  $4.3  million  per  year. As  of 
December 31,  2016,  the  Company  had  approximately  $6.2  million  of  foreign  net  operating  loss  carryforwards  in  various 
jurisdictions. Most of the Company’s foreign net operating losses can be carried forward indefinitely, with certain amounts expiring 
from 2017 to 2026.

For the year ended December 31, 2015, long-term deferred income tax liabilities in the amount of $0.2 million have been 

included in other non-current liabilities on the Company’s Consolidated Balance Sheet. 

The Company recorded an income tax benefit of $0.7 million during the year ended December 31, 2016, income tax expense 
of $15.2 million during the year ended December 31, 2015 and an income tax benefit of $52.6 million during the year ended 
December 31, 2014. The difference between the income tax provision at the statutory rate and the Company’s effective income tax
benefit for the year ended December 31, 2016 was the result of research and development tax credits and additional tax deductions 
from share-based compensation, sometimes referred to as excess tax benefits, partially offset by state taxes, non-deductible expenses 
and other permanent items. Excess tax benefits arise when tax deductions recognized by the Company with respect to share-based 
compensation exceed  the  compensation  cost attributable to  share-based  compensation  that  was recognized  in  the Company’s 
consolidated financial statements.  The difference between the income tax provision at the statutory rate and the Company’s effective 
income tax provision for the year ended December 31, 2015 was the result of state taxes, non-deductible expenses and other 

F-24 

 
   
 
   
CRAY INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) 

permanent items, partially offset by research and development tax credits. The tax benefit recorded by the Company during the year
ended  December 31, 2014 was  primarily  attributable  to  a partial  reduction,  in  the  amount  of $55.7 million, of  the  remaining 
valuation allowance that was held against the Company’s U.S. deferred tax assets. 

The  Company’s  decision  to  partially  reduce,  in  the  amount  of  $55.7  million,  the  valuation  allowance  held  against  the 
Company’s U.S. deferred tax assets during the year ended December 31, 2014 was based upon an evaluation of all available positive
and negative evidence, known business risks and industry trends. The Company considers its actual results over several years to
have stronger weight than other more subjective indicators, including forecasts, when considering whether or not to establish or
reduce a valuation allowance on deferred tax assets and believes that its ability to forecast results significantly into the future is 
limited due to the rapid rate of technological and competitive change in the industry in which it operates. As of December 31, 2014 
the Company had generated U.S. pre-tax income in each of the last three years and cumulative U.S. pre-tax income of $184.8 
million ($51.1 million excluding the impact of the sale of the Company’s interconnect hardware development program) over the last
three years. In addition to the Company’s cumulative income position, the assessment of the Company’s ability to utilize its U.S. 
deferred tax assets included an assessment of forecasted domestic and international earnings over a number of years, which included 
the impact of several major contracts that were finalized during the fourth quarter of 2014. 

The Company’s conclusion about the realizability of its deferred tax assets, and therefore the appropriateness of the valuation
allowance, is reviewed quarterly and could change in future periods depending on the Company’s future assessment of all available
evidence in support of the likelihood of realization of its deferred tax assets. If the Company’s conclusion about the realizability of 
its deferred tax assets and therefore the appropriateness of its valuation allowance changes in a future period, it could record a 
substantial tax provision or benefit in the Consolidated Statements of Operations when that occurs. 

The valuation allowance on deferred tax assets decreased by $0.8 million, $0.7 million and $67.7 million in 2016, 2015 and 
2014, respectively. The decrease in the valuation allowance for the year ended December 31, 2014 included a reduction, in the 
amount of $55.7 million, of the valuation allowance held against the Company’s U.S. deferred tax assets based upon an assessment
of all positive and negative evidence relating to future years. 

As of December 31, 2016, undistributed earnings, in the approximate amount of $14.5 million, relating to the Company’s 
foreign subsidiaries are considered to be permanently reinvested; accordingly, no provision for U.S. federal and state income taxes
has been provided thereon. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company would be 
subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to the various
foreign countries. Determination of the amount of unrecognized deferred U.S. income tax liability is not practicable due to the
complexities associated with this hypothetical calculation. As of December 31, 2016, the Company’s foreign subsidiaries held cash 
in the amount of $14.3 million. 

The following table summarizes changes in the amount of the Company’s unrecognized tax benefits for uncertain tax positions 

for the three years ended December 31, 2016, 2015 and 2014 (in thousands):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) 

The balance of unrecognized tax benefits as of December 31, 2016 was $6.5 million of tax benefits that, if recognized, would 
affect the effective tax rate. It is not anticipated that the balance of unrecognized tax benefits will significantly change over the next 
twelve months. 

The  Company  or  its  subsidiaries  file  income  tax  returns  in  the  U.S. federal  jurisdiction  and  various  state  and  foreign 
jurisdictions. The Company defines its major tax jurisdictions to include Australia, Germany, the United Kingdom and the United
States. The Company is no longer subject to income tax examinations with respect to Australia for periods before 2011 and for 
periods  before  2015  in  Germany  and  the  United  Kingdom,  respectively.  With  respect  to  the  U.S.  federal  and  various  state 
jurisdictions the Company is no longer subject to income tax examinations with respect to periods before 2013, although in such
jurisdictions net operating loss and tax credit carryforwards generated in a year are subject to examination and adjustment for at least 
three years following the year in which such losses or credits are actually used to offset taxable income. 

Estimated interest and penalties are recorded as a component of interest expense and other expense, respectively. Such 

amounts were not material for 2016, 2015 and 2014. 

NOTE 14    CREDIT FACILITIES 

As of December 31, 2016, the Company had a $50.0 million revolving line of credit, or Credit Facility, with Wells Fargo 
Bank, National Association, designed to be used for general corporate purposes, including working capital requirements and capital
expenditures.  The Credit Facility also supports the issuance of letters of credit. The Credit Facility is secured by a first priority lien 
in all of the Company’s accounts receivable and other rights to payment, general intangibles, inventory and equipment. 

Any borrowings under the Credit Facility bear interest at either a fluctuating rate equal to the daily one month LIBOR rate plus
a margin of 1.25% or a fixed interest rate for one, three or six months equal to the LIBOR rate for the applicable period plus a
margin of 1.25%.  The Company is also required to pay the lender customary letter of credit fees, and a commitment fee of 0.18%
per annum in respect of the unutilized commitment amount under the Credit Facility. The Credit Facility requires that the Company 
maintain certain financial ratios and restricts its ability to incur additional indebtedness, pay dividends or distributions, create liens 
on assets, and engage in certain other activities. The Company was in compliance with all of its financial covenants as of the end of 
each quarter for the year ended December 31, 2016. The Credit Facility matures in December 2017. 

The Company made no draws and had no outstanding cash borrowings on the credit facility as of December 31, 2016.  

As of December 31, 2016, the Company had $3.3 million in USD equivalent value in outstanding letters of credit and $1.7 
million  in restricted  cash  associated with  certain  letters  of  credit  to secure  customer prepayments  and other  customer  related 
obligations. 

NOTE 15    SHAREHOLDERS’ EQUITY 

Preferred Stock:    The Company has 5,000,000 shares of undesignated preferred stock authorized, and no shares of preferred 

stock outstanding.

Common Stock:    The Company has 75,000,000 authorized shares of common stock with a par value of $0.01 per share.

Stock Plans:    As of December 31, 2016, the Company had one active equity incentive plan that provides shares available for 

option, restricted stock and restricted stock unit grants to employees, directors, executives and others.

Stock Options:    In determining the fair value of stock options, the Company uses the Black-Scholes option pricing model. 
The following key weighted average assumptions were employed in the calculation for the indicated years ended December 31:

Risk-free interest rate .............................................................................
Expected dividend yield ........................................................................
Volatility ................................................................................................
Expected life (in years) ..........................................................................

The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The Company does not 
anticipate declaring dividends in the foreseeable future. Volatility is based on historical data. The expected life of an option is based 

F-26 

CRAY INC. AND SUBSIDIARIES 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued) 

on the assumption that options will be exercised, on average, about two years after vesting occurs. The Company recognizes 
compensation expense for only the portion of options that are expected to vest. Therefore, management applies an estimated 
forfeiture rate that is derived from historical employee termination data and adjusted for expected future employee turnover rates. 
The estimated forfeiture rates applied to the Company’s stock option grants for the years ended December 31, 2016, 2015 and 2014
were 8.0%, 8.0%, and 8.3%, respectively. If the actual number of forfeitures differs from those estimated by management, additional 
adjustments to compensation expense may be required in future periods. The Company’s stock price volatility, option lives and 
expected forfeiture rates involve management’s best estimates at the time of such determination, which impact the fair value of the 
option calculated under the Black-Scholes methodology and, ultimately, the expense that will be recognized over the vesting period 
or requisite service period of the option. The Company typically issues stock options with a four-year vesting period (the requisite 
service period) and amortizes the fair value of stock options (share-based compensation cost) ratably over the requisite service
period. Options to purchase shares expire no later than ten years after the date of grant.

As of December 31, 2016, there was $13.8 million of aggregate intrinsic value of outstanding stock options, including $13.8 
million of aggregate intrinsic value of exercisable stock options. Intrinsic value represents the total pretax intrinsic value for all “in-
the-money” options (i.e., the difference between the Company’s closing stock price on the last trading day of 2016 and the exercise 
price, multiplied by the number of shares of common stock underlying the stock options) that would have been received by the 
option holders if all option holders had exercised their options on December 31, 2016. This amount changes, based on the fair 

F-27

market value of the Company’s stock. Total intrinsic value of options exercised was $4.0 million, $5.0 million, and $10.2 million for 
the years ended December 31, 2016, 2015 and 2014, respectively. 

Restricted Stock:    During 2016, 2015 and 2014, the Company issued an aggregate of 9,893, 45,175, and 463,734 shares of 
restricted stock, respectively, to certain directors, executives and other employees. The grant date fair value of these grants was 
approximately $0.3 million, $1.4 million, and $13.3 million for 2016, 2015 and 2014, respectively. Share-based compensation 
expense is recorded over the vesting period, which is generally one year for non-employee directors and four years for officers and 
employees of the Company.

The  estimated  forfeiture  rates  applied  to  the  Company’s  service  vesting  restricted  stock  grants  during  the  years  ended 
December 31, 2016, 2015 and 2014 were 8.0%, 8.0% and 6.3%, respectively. The aggregate fair value of restricted shares vested 
during 2016, 2015 and 2014 was $7.7 million, $14.2 million, and $11.9 million, respectively. Performance vesting restricted shares 
totaling 476,000 will expire unvested at the time of filing this Form 10-K as the criteria for vesting was not satisfied during the 
performance period. This will also have the impact of reducing the number of shares of outstanding Common Stock by 476,000 
shares. The remaining performance vesting restricted shares are eligible to vest in 2017. No compensation cost has been recorded for 
these grants. 

Restricted Stock Units:    During 2016 and 2015, the Company issued an aggregate of 244,160 and 984,850 restricted stock 
and performance vesting restricted stock units, respectively, to certain executives and other employees. The grant date fair value of 
these grants was approximately $8.0 million and $29.5 million for 2016 and 2015, respectively. There were no restricted stock units 
issued or outstanding as of December 31, 2014. Restricted stock units have similar vesting characteristics as restricted stock but are 
not outstanding shares and do not have any voting or dividend rights. The Company records share-based compensation expense over
the vesting period. At the time of vesting, a share of common stock representing each restricted stock unit vested will be issued by 
the Company.

The estimated forfeiture rates applied to the Company’s service vesting restricted stock unit grants during the years ended 
December 31, 2016 and 2015 were 8.0% and 8.0%, respectively. The aggregate fair value of restricted stock units vested during 
2016 was $1.9 million.  The performance vesting restricted stock units are subject to performance measures that are currently not 
considered “probable” of attainment and as such, no compensation cost has been recorded for these units. The performance vesting
restricted stock units are eligible to vest between 2017 and 2020. 

Share-based Compensation Expense:    Including performance-based equity awards, the Company had $43.1 million of total 
unrecognized compensation cost related to unvested stock options, unvested restricted stock and unvested restricted stock units as of 
December 31, 2016. Excluding the $27.7 million of unrecognized compensation cost related to unvested restricted stock and 
unvested restricted stock units that are subject to performance measures that are currently not considered “probable” of attainment, 
unrecognized compensation cost is $15.4 million. No compensation expense is recognized for unvested restricted stock or unvested
restricted stock units subject to performance measures that are not considered “probable” of attainment. Unrecognized compensation

The following table presents unaudited quarterly financial information for the two years ended December 31, 2016. In the 
opinion of management, this information contains all adjustments, consisting only of normal recurring adjustments, necessary for a 
fair presentation thereof. 

The operating results are not necessarily indicative of results for any future periods. Quarter-to-quarter comparisons should not 
be relied upon as indicators of future performance. The Company’s business is driven by a few significant contracts and, as a result, 
the Company’s operating results are subject to very large quarterly fluctuations. The Company’s earnings per share for the full year 
may not equal the sum of the four quarterly earnings per share amounts because of common share activity during the year.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Shareholders 
Cray Inc. 

We have audited the accompanying consolidated balance sheets of Cray Inc. and Subsidiaries (“the Company”) as of December 31, 
2016 and 2015, and the related consolidated statements of operations, comprehensive income, shareholders’ equity, and cash flows
for each of the years in the three-year period ended December 31, 2016.  Our audits also included the financial statement schedule 
listed in the index at item 15(a)(2).  The Company’s management is responsible for these consolidated financial statements and 
schedule.  Our responsibility is to express an opinion on these financial statements and schedule based on our audits. 

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated
financial position of Cray Inc. and Subsidiaries as of December 31, 2016 and 2015, and the consolidated results of their operations 
and their cash flows for each of the years in the three-year period ended December 31, 2016, in conformity with accounting 
principles generally accepted in the United States.  Also, in our opinion, the related financial statement schedule, when considered in 
relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
Company’s internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control - 
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and 
our report dated February 10, 2017, expressed an unqualified opinion.

as amended, including, but not limited to, statements related to Cray’s financial guidance and expected operating results and its product development, sales and delivery plans. 
These statements involve current expectations, forecasts of future events and other statements that are not historical facts. Inaccurate assumptions and estimates as well as known 
and unknown risks and uncertainties can affect the accuracy of forward-looking statements and cause actual results to differ materially from those anticipated by these forward-
looking statements. Factors that could affect actual future events or results include, but are not limited to, the risk that Cray does not achieve the operational or financial results that 
it expects, the risk that Cray will not be able to secure orders and acceptances for Cray products in any particular periods at expected levels or with the anticipated timing, the risk 
that the segments of the high-end of the supercomputing market that Cray targets do not recover from the current downturn as early or as completely as expected or at all, the risk 
that  government  funding  for  research  and  development  projects  is  less  than  expected,  the  risk  that  new  third-party  processors  and  other  components  for  our  systems  are  not 
available with the anticipated performance, timing or pricing, the risk that the systems ordered by customers are not delivered when expected, do not perform as expected once 
delivered or have technical issues that cannot be corrected within the time for planned acceptances, the risk that the acceptance process for delivered systems is not completed, or 
customer acceptances are not received, when expected or at all, the risk that Cray is not able to successfully sell products and services in the big data, artificial intelligence and 
commercial markets as expected or at all, the risk that the expense to address Cray systems at customer sites that have issues with third-party components or with Cray components

anticipated gross margin or expense levels and such other risks as identified in Cray’s annual report on Form 10-K for the period ended December 31, 2016, and from time to time
