BUSINESS 

Overview  

We develop, manufacture and sell optoelectronic products that transmit, receive and switch high speed digital optical 
signals for communications networks. Our products address the highest speed over distance applications and are designed 
for 100G and beyond data rates, such as at 200G, 400G and, in the near future, 600G, for telecom and datacenter or content 
provider networks.   

Our 100G and beyond products use our Advanced Hybrid Photonic Integration technology. These products using our 
advanced  technology  are  the  core  focus  of  our  strategy,  and  we  believe  that  they  are  an  important  competitive 
differentiator.   

In December 2016, we entered into an asset purchase agreement to sell certain assets of our access and low speed 
transceiver  product  lines  (the  “Low  Speed  Transceiver  Products”)  to  APAT  Optoelectronics  Components  Co.,  Ltd. 
(“APAT OE”) of Shenzhen, China. In January 2017, we closed the sale of these assets which generated approximately 
15%, 27% and 36% of our total revenue in 2016, 2015 and 2014, respectively. All of these product lines were part of our 

5 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Network Products and Solutions group and include the low speed passive optical network, or PON, products for which the 
end-of-life plan was announced in mid-2016. 

Our  module products incorporate our vertically integrated, high performance components, including ultra-narrow 
linewidth tunable lasers (NLW-TLs), high speed electro-absorbtively modulated lasers (EMLs), high bandwidth coherent 
receivers (ICRs), high bandwidth  micro-modulators (Micro-MOD), high bandwidth trans-impedance amplifiers (TIAs) 
and high bandwidth laser and modulator drivers.  In addition to integrating these components into our own modules, we 
sell these components to other industry leaders who use them in their highest performance products.  We believe that our 
strength in these and other high performance components places us in a strong competitive position as we increasingly add 
to our module product line. 

100G  and  beyond  networks  are  one  of  the  highest  growth  segments  of  the  optical  communications  market,  and 
support the rapid expansion of telecom backbone, datacenter and content provider networks, accommodating increased 
mobile traffic. Prior to 2016, revenue growth from our high speed products was mainly driven by the adoption of our 100G 
coherent products in the Long Haul market sector.  We expect our future growth in the 100G and beyond segment to be 
driven primarily by the increased adoption of our high speed products in the much larger Metro market sector and in the 
high-speed datacenter interconnect market as well as the large web-scale datacenter market.   

Coherent transmission uses not only amplitude but also phase and polarization to significantly increase data rates 
over conventional  “on-off”  transmission protocols.  Coherent transmission does not require complete isolation of each 
channel by optical filters and therefore can flexibly and efficiently switch the signal on an individual wavelength without 
conflict  or  contention  between  wavelengths,  a  feature  that  is  required  for  Software  Defined  Optical  Networks,  or 
SDON. Software  Defined  Optical  Networks  radically  increase  the  flexibility  and  efficiency  of  metro  networks  and, 
combined with the ten-fold increase in data-rates achievable with coherent transmission, mark a very large improvement 
in cost performance for metro scale networks.  In addition, the necessary equipment to implement a metro scale network 
is significantly reduced, especially using flex-coherent transceivers and Colorless, Directionless and Contentionless (CDC) 
Switches. 

 The  benefits  of  coherent  transmission  have  made  it  a  preferred  technology  for  advanced  high  speed 
telecommunications networks for distances of 80 kilometers to 2000 kilometers.  We believe that our Advanced Hybrid 
Photonic Integration technology enables us to effectively address the challenges inherent in precision and high volume 
manufacturing of optical components for coherent transmission. 

Our products also serve high performance, non-coherent segments of the datacenter and enterprise  market  which 
require the fastest speeds transmitted over relatively long distances within datacenters.  We are a leading provider of EMLs 
and  our  client  and  datacenter  transceiver  modules  incorporate  these  EMLs  to  deliver  high  power  and  high  quality 
modulation for superior speed and distance performance. 

Our accelerating revenue growth reflects the rapid adoption and deployment of high speed 100G above networks 

across the global telecom and datacenter network applications.  

We sell our products to the world’s leading network equipment manufacturers, including Nokia Corporation, or 

Nokia (formerly Alcatel-Lucent S.A., or Alcatel-Lucent, which was acquired by Nokia in January 2016), Ciena 
Corporation, or Ciena, Cisco Systems, Inc. and Huawei Technologies Co., Ltd., or Huawei. These four companies 
accounted for approximately 76% and 79% of our total revenue in 2016 and 2015, respectively. Other leading customers 
are FiberHome Telecommunications Technologies Co., Ltd., or FiberHome, a major Chinese telecommunications system 
provider, and Acacia Communications, Inc., or Acacia, a fast growing vendor of optical interconnects. 

Our leading customers serve the telecom market and also the datacenter market, represented by companies including 
Amazon,  Facebook,  Google  and  Microsoft.  Large  network  equipment  and  optical  module  companies,  together  with 
emerging content providers and datacenter operators, are the focus of our strategy due to their important positions in high 
speed and related communications networks markets.   

6 

 
 
 
 
 
 
 
 
 
 
We believe our Advanced Hybrid Photonic Integration technology is well positioned to serve the highest speed next-
generation 200G, 400G and 600G products and applications. Using this core technology we produce photonic integrated 
circuits, or PICs, that comprise both arrayed and individual photonic functional elements using optimized materials systems 
and  processes  from  our  in-house  Silicon,  Indium  Phosphide  and  Gallium  Arsenide  wafer  fabrication,  plus  Silicon 
Germanium  chips  produced  in  foundries.  These  individual  PICs  from  different  materials  are  then  combined  using  our 
hybrid integration technology to make complete products, such as our Integrated Coherent Receiver (“ICR”) and our Multi-
cast  Switch  (“MCS”)  for  100G  and  beyond  coherent  transport  and  Metro  applications  and  our  100G  to  400G  CFPx 
transceivers for datacenter and telecom client networks. 

100G and beyond coherent technology has become widely used in the Long Haul market segment over the last 

several years, but has only recently begun to be deployed in the much larger Metro and the emerging datacenter 
interconnect, or DCI, sector of the market.  While the cost per port deployed typically declines every year due to 
technological advances, 100G coherent port demand represents a high growth opportunity for suppliers of components, 
modules and systems for the 100G coherent Metro and DCI markets.  In addition, Metro coherent ports include ports that 
have “flex coherent” features, which can be used not only in the Metro market but also in the Long Haul market and 
therefore have to support the highest performance applications at deployment.  

Our products for the rapidly growing coherent Metro market, include Integrated Coherent Receivers, ultra-narrow 
linewidth tunable lasers and multi-cast switches.  Our multi-cast switches similarly are used by webscale content providers 
for software definition of their network configuration.  Also, we have introduced coherent transceiver modules that are 
used for the Metro market as well as the datacenter interconnect market, such as high speed coherent CFP-DCO and CFP2-
ACO transceivers. 

We have strengthened our technology leadership through several strategic acquisitions as noted below over the last 

five years. 

• 

• 

• 

In October 2011, we acquired Santur Corporation, or Santur, a producer of tunable lasers and modulators 
for coherent transmission and of 100G client side transceiver modules. Santur’s capabilities included 
array DFB (distributed feedback) lasers, silicon photonics and photonic integration of lasers, modulators 
and photodiode elements.  

In March 2013, we acquired the optical component business unit of LAPIS Semiconductor Co., Ltd., 
located in Japan, now known as NeoPhotonics Semiconductor. This business is a leading producer of high 
performance communications lasers, photodiode devices and optical control electronic devices which 
enable our leading market positions and increasing vertical integration in our coherent products including 
ultra-narrow linewidth tunable lasers and coherent receivers. NeoPhotonics Semiconductor also produces 
high speed lasers and control semiconductors for high speed datacenter and client side applications, 
providing vertical integration for our high speed telecom client side and datacenter module products and 
stand-alone products to the industry.  

In January 2015, we acquired the ultra-narrow linewidth tunable laser business of EMCORE 
Corporation’s (EMCORE), expanding our position as a supplier of tunable laser for coherent 
communications. The EMCORE ultra narrow linewidth tunable laser products are used in the industry’s 
highest speed applications and are critical components that are used with our highest speed and highest 
bandwidth receiver products for the emerging data rates of 400G and 600G.  

We have research and development and wafer fabrication facilities in San Jose and Fremont, California and in 

Tokyo, Japan that coordinate with our research and development and manufacturing facilities in Dongguan, Shenzhen 
and Wuhan, China and Ottawa, Canada. We additionally do limited research and development and manufacturing in 
Moscow, Russia. We use proprietary design tools and design-for-manufacturing techniques to align our design process 
with our precision nanoscale, vertically integrated manufacturing and testing. We believe we are one of the highest 
volume PIC manufacturers in the world and that we can further expand our manufacturing capacity to meet market 
needs.

Industry Background 

The new era of connectedness is increasingly universal and demands that the capacity of the digital 

communications networks must increase exponentially. Smartphones and related portable devices have emerged as the 
preferred vehicle connecting the digital world, with more than one billion current smartphone users and a rapidly 
increasing volume of other portable devices. Not only are more people connected to the mobile web, but they are 
connecting at increasingly higher data rates and requiring higher bandwidths. Wireless network deployments have 
progressed from third generation (3G) to fourth generation (4G/LTE) and are moving toward fifth generation (5G), 
representing a 10X increase in bandwidth over five years, and providing end-users with ever-increasing download speeds 
and mobility, and enable IoT machine-to-machine communication for the integration of autonomous vehicles and other 
disruptive applications. 

Further the deployment of modern communications has rapidly expanded from being the domain of telecom 
service providers to include today’s deployments by enterprises, content providers and merchant data storage and service 
“mega” datacenter enterprises.  The rapid rise of internet traffic that is going through mega datacenters operated 
primarily by leading content companies, such as Amazon, Apple, Facebook, Google and Microsoft (i.e. Microsoft 
Azure), has created a large and rapidly growing new market for optical modules and components in general, but more 
specifically for high speed optical modules and components.  

The revolution in the power of low cost computing devices is associated with Moore’s Law. Moore’s Law refers to 

an observation made by Intel co-founder Gordon Moore in 1965 that the number of transistors per square inch on 
integrated circuits had doubled every two years since their invention and a prediction that this trend would continue. In 
the domain of optical communications, a similar revolution, progressing at a similar rate, is driven by the increased 
speed, smaller size and lower cost achieved by photonic integration.  

A single optical fiber can carry nearly 100 individual wavelengths (colors), each of which can now support 100 
gigabits per second of capacity. Each of these wavelengths requires a 100G or higher speed transmitter and receiver, 
which can be tuned to any of the 100 separate channels. Thus, using 100G coherent technology and industry standard 
compression (MPEG-2), a single fiber can carry approximately 500,000 individual high definition full motion movies 
simultaneously over one fiber. 

Digital Optical Communications Market Structure  

The digital optical communications market has two main sectors, telecom (Long Haul, Metro, access) and 

Datacom (datacenter). The telecom sector includes the global backbone of Long Haul and Metro communications. It also 
includes local access links to end users. The Datacom and datacenter sector includes connections in webscale datacenters 
as well as traditional “enterprise” networks. As datacenters proliferate within metropolitan sized geographies, a very 
rapidly growing Datacenter Interconnect market has emerged which resembles the metro market in its bandwidth and 
distance needs and utilizes similar optical technologies and products.   

While the Metro market is the largest volume, it most often follows the Long Haul telecom sector in technology 

deployment, notably of coherent 100G and beyond technologies. The Long Haul telecom sector is the first adopter of the 
highest speed and most advanced communication links, and typically migrates over time into the Metro sector as costs 
are reduced such that they are economical in the shorter but more numerous Metro network links, with its commensurate 
lower traffic densities prior to aggregation for Long Haul transport.  

The Datacom market includes web-scale data centers and infrastructure for cloud based services as well as 

traditional enterprise networks. Companies, such as Amazon, Apple, Facebook, Google and Microsoft, are steadily 
increasing investments in very large datacenters as they implement cloud-based “big data” services that can be crowd-
sourced and crowd-distributed, and that utilize machine-to-machine and inter-datacenter transactions to power the mobile 
web.  Connections between such very large datacenters over a metro-sized area are an emerging high growth market for 
“big pipes” using dedicated 100G and beyond digital optical connections from datacenter to datacenter (inter-datacenter 
and DCI). Connections within datacenters (intra-datacenter) and from datacenter to a telecommunications carrier are also 
moving to 100G and beyond speeds, although somewhat behind Metro, DCI and long haul.  

8 

 
 
 
   
 
 
 
   
   
  The Datacom market is often the most cost sensitive sector of digital optical communications due to high 
volumes and to shorter lifetime requirements, and therefore it typically begins to adopt leading edge speeds after those 
speeds penetrate the Metro sector of the telecom market segment.  

From this market structure, we believe that a technology leader must achieve a leadership position in the Long 

Haul telecom sector as the basis for commercializing the most advanced technology and then extending that technology 
to the Metro and DCI sectors and to additional applications within datacenters and other Datacom applications.  

Digital Optical Communications Network Equipment  

The structure of the industry that supplies the network equipment for telecom digital optical communications 
networks has largely concentrated down to leading vendors which include: Nokia (formerly Alcatel-Lucent, which was 
acquired by Nokia in January 2016), Ciena, Cisco, Coriant, Fujitsu Limited, Fiberhome, Huawei, Infinera Corporation, 
NEC Corporation and ZTE Corporation.  

Major suppliers of network equipment to the Datacom and datacenter market include Arista Networks, Nokia, 

Brocade Communications Systems, Inc., Cisco, Huawei and Juniper Networks, Inc. At the optical module and 
component level, Broadcom Limited, or Broadcom (resulting from the acquisition of Broadcom Corporation by Avago 
Technologies Ltd., or Avago), Finisar and Sumitomo Electric Device Innovations, Inc., or Sumitomo, are leading 
merchant suppliers and some larger network equipment companies like Huawei and Cisco have divisions or affiliates 
(such as HiSilicon in the case of Huawei) that are captive suppliers. Furthermore, some of the larger webscale content 
providers, such as Google, Microsoft and Facebook, are beginning to design and source their own optical network 
systems equipment from contract manufacturing partners.  

Recent changes in switch architectures are rapidly moving new installations to higher speed 25G dataflows (such 
that four such signal paths provide 100G comprised of four 25G signals, or “4x25G”), resulting in a fast growing 100G 
module market for connections inside the datacenter and “big pipes” for data connections between datacenters, or 
datacenter interconnects (DCI), at 100G and 200G, and moving to 400G and 600G, data rates.  

The main photonic operational blocks or modules required for digital optical communications are transmitters, 
receivers and, where the network is branched, optical switches. Transmitters and receivers are often combined into single 
modules which are called transceivers and can be configured into line cards, daughter cards and transponders, or digital 
or analog modules. At the high end, such as Long Haul, a transmitter and receiver can be paired and combined with 
signal processing electronics to error correct and restore degradation which affects the signal after traveling long 
distances, in which case the unit is referred to as a transponder. For high speeds and high bandwidth each of these 
product types requires photonic integration at the most advanced and complete level to deliver the required performance 
and functionality while being manufacturable at scale and competitive in cost.  

Switching products, which switch different colors, or signal channels, down different branches of the network, 

have thus far been Reconfigurable Optical Add/Drop Multiplexers (ROADMs) consisting of Wavelength Selective 
Switches (WSSs). For 100G coherent networks, a new type of optical switch, the Multi-Cast Switch (MCS), has been 
developed and introduced to eliminate contention in 100G coherent switching. The need to eliminate contention is being 
driven by the move to SDON, which is important to both telecom network requirements and content provider 
networks.  A “contentionless” architecture uses both traditional “Wavelength Selective Switches” and the new MCS, 
which we supply.  One or more MCSs are deployed initially with each ROADM node, and then additional multicast 
switches are deployed over time as traffic growth demands with as many as eight MCS devices for each node, allowing 
networks to efficiently expand as needed. This type of switch is Colorless, Directionless, Contentionless (CDC), and its 
function is optimized for 100G and beyond coherent networks.  

Digital Optical Communications Technology Background  

Advances in cost performance in photonic integration have followed a path that has been similar to electronic 

integrated circuits.  

9 

 
   
   
 
 
 
   
 
   
 
 
The main objectives for technology advances in electronic digital integrated circuits and in integrated optical 
digital devices are similar, and are based on the drive towards lower cost and higher performance with expanding scale. 
In integrated optics these main objectives also include higher speed, lower power, smaller or denser form factor, and 
lower cost. 

In both electronics and optics these objectives require ever increasing integration and miniaturization. In optics, 
however, we believe advanced hybrid integration is required for the highest performance products. Hybrid integration for 
digital optical devices incorporates multiple types of materials substrates, rather than just one, as in silicon, for an 
electronic integrated circuit.  

Complete advanced photonics integration capability requires at least three materials substrate systems: Indium 

Phosphide for active devices such as lasers, photodiode detectors, modulators, and amplifiers; Silicon or planar doped 
silicon dioxide (silica) for wave guides, filters, interferometers and other passive devices; and Gallium Arsenide or 
Silicon Germanium for drivers and control functions at the speeds necessary for 100G. The integration of more than one 
material substrate is called hybrid integration, and Advanced Hybrid Photonic Integration enables products in the 100G 
and beyond domain. 

Advantages and Challenges of Coherent Transmission  

Coherent digital optical transmission technology has increased the native capacity of a fiber optic link tenfold, 

versus a transmission modulation of simple on/off such as in 10G WDM networks. Coherent transmission modulation 
encodes information via phase and polarization, and the permutations of these variables are many times greater than 
on/off.  

To create a detectable error-free signal in the coherent modality requires that each color (wavelength) transmitted 

be much purer than would be required for lower speed protocols. The primary enabler of such ultra-narrow line width 
(NLW), that is, an ultra-pure and stable color, is a new generation of the most advanced lasers. These NLW lasers must 
be paired with a new generation of receivers that decode phase and polarization through comparison with another NLW 
laser in a PIC-interferometer. Ultra-narrow line width lasers are built on Indium Phosphide substrates while the receivers 
utilize a Silicon or Indium Phosphide interferometer and Indium Phosphide photo detectors.  

These 100G and beyond coherent optical transmission devices require tighter tolerances of material thickness and 
other critical dimensions than do components operating at 10G. For 100G, a new generation of technologies, including 
faster Gallium Arsenide drivers, is required to suitably process transmission signals in both the laser transmitter and the 
detector and receiver. As transmission speeds move to 200G, 400G and even 600G through higher order modulation 
protocols and higher symbol rates, even higher performance optical components are required.  We believe we have 
established and characterized the full range of driver, laser and detector technologies required for implementing 100G, 
200G, 400G and 600G coherent systems, a capability that we believe is held by only a few companies.  

Our Core Technology and Hybrid Photonic Integration Platform  

We have core technology capabilities in optoelectronics that enable the high speed, high bandwidth, high 
performance optoelectronics products and we believe we have developed or acquired all necessary capabilities required 
for producing high performance Advanced Hybrid Photonic Integrated optoelectronic devices for the most stringent 
performance requirements and operating conditions. Our core technology leverages a unique multi-material platform that 
includes:  

Indium Phosphide (InP): Indium Phosphide is used to produce efficient lasers, sensitive photo detectors and 
modulators in the wavelength window typically used for telecommunications, i.e. 1.55 micron wavelengths, as it is 
a direct bandgap III-V compound semiconductor material. InP is the most important material for the generation of laser 
signals and the detection and conversion of those signals back to electronic form.  

10 

 
 
 
 
 
 
   
   
 
 
   
   
Silicon (Silicon Photonics and Planar Lightwave Circuits): Silicon is a multi-attribute material that is efficient for 

electronics and versatile for integration while being very inefficient in generating or detecting light in the telecom 
wavelength window as it is an indirect bandgap semiconductor material. Consequently, waveguides of Silicon or doped 
silicon dioxide (silica) exhibit very low optical loss and are ideal for switching, filtering or interferometric applications 
and active elements including modulators and switches can be produced using Silicon waveguides.  

Gallium Arsenide (GaAs): Gallium Arsenide can operate at very high speeds and is well suited to make analog 
integrated circuit drivers for high speed lasers and modulators due to its high electron mobility. GaAs is a direct bandgap 
III-V compound semiconductor material, but unlike InP, GaAs does not lase in the telecom wavelength window.  

Silicon Germanium (SiGe): Silicon Germanium is an alloy of Silicon and Germanium that is used to manufacture 

mixed signal and analog integrated circuits and is well suited for high speed amplifiers used in 100G systems. SiGe 
devices are made using standard silicon processing techniques in commercial foundries.  

ASIC Development:  We have applied in-house capability for customized integrated circuit design and 

development for specific purpose applications in high speed optical digital control and management, including certain 
developments in signal processing.  Such products are deployed in GaAs, SiGe and silicon materials platforms. 

We have developed design, integration and manufacturing approaches and techniques to produce advanced, high 
speed integrated solutions leveraging each of these in-house materials technology and high speed digital optoelectronics 
platforms.

Our Strategy  

Key elements of our strategy include: 

•  Continue innovating to develop industry-leading comprehensive technology for Advanced Hybrid Photonic 
Integration. We have strengthened and expanded our technology platforms for comprehensive advanced 
photonic integration, in part from acquisitions and from internally funded development. We expect to 
continue to combine our mixed platform approach to design and produce the highest performance optical 
signal processing solutions.  

•  Capture major customer share for the most advanced modules and components at the top suppliers of state 
and users of the art network equipment. We intend to deepen our relationships with our strategic customers 
by increasing design wins in their systems, including Ciena, Cisco, Huawei and Nokia, plus certain others, 
which are market leaders or emerging players in 100G and beyond coherent systems.   

•  Offer complete optoelectronic solutions for 100G to 400G and beyond for leading edge Telecom and 
Datacom market segments. We expect to continue to introduce Coherent Transmitter, Receiver and 
Transceiver Module products that are optimized for the highest speeds so that our product line will include 
each of the major types of the most advanced products.  

•  Achieve growth in integrated optical applications that leverage our core technology of advanced 

optoelectronic products. We intend to provide state of the art products and solutions to industry leading 
customers to advance our goal of achieving continuous improvement in operating performance, profitability 
and growth.  

•  Focus on high growth segments that leverage our leadership in Advanced Hybrid Photonic Integration and 
that contribute to our profitable growth. We plan to continue to develop our products and solutions to 
capture new opportunities, such as emerging 400G and 600G connections in both carrier networks and 
within and between large datacenters.  

•  Extend our product line into additional segments of the network that will benefit from ultra-high speed 

performance. We intend to penetrate the emerging market for 100G connections both within and between 
mega-datacenters. In this segment we are targeting major users and builders of datacenters and datacenter 
equipment, such as Amazon, Apple, Facebook, Google and Microsoft, as they develop some of their own 
network equipment. We believe our technology and product line is well positioned to penetrate this market. 

•  Pursue acquisitions that extend our leadership position in advanced optoelectronic integration. We may 
opportunistically pursue acquisitions that we believe provide complementary technology and that can 
accelerate our growth and strengthen our market position. 

Our Technology  

We have developed expertise in the design, large-scale fabrication, high-volume module manufacturing and 

commercial deployment of high speed digital optics and signal processing products that are based on our Advanced 
Hybrid Photonic Integration products and technologies. The process of designing and manufacturing advanced 
optoelectronic integrated devices in high volume with predictable, well-characterized performance and low 
manufacturing costs is complex and multi-faceted. We have developed the technologies, using multiple materials 
platforms for photonic integration, that are required to design and manufacture complex, high-performance 
optoelectronic components, modules and subsystems for fiber optic networks. The basic elements of our technology are 
as follows:  

Mixed-material platform and optoelectronic integration technology. We utilize a set of proprietary integration 

platforms that provide optoelectronic functionality on silicon and other integrated compound semiconductor substrates 
including Indium Phosphide, Gallium Arsenide and Silicon Germanium and integrated combinations of these platforms. 

12 

 
 
 
 
 
 
 
 
 
 
 
We utilize micron and sub-micron scale structures of multiple silicon dioxide and Indium Phosphide waveguides to 
fabricate optoelectronic functional elements such as lasers, detectors, modulators, interferometers, integrated optical 
filters, switches and variable attenuators. We integrate these functional design elements into optoelectronic devices to 
achieve a desired functionality and specification that is incorporated into our products. Similarly, we use Gallium 
Arsenide and Silicon Germanium integration platforms for drivers, amplifiers and related high-speed electronic control 
functions for our integrated optoelectronic devices.  

Advanced Hybrid Photonic Integration. Through precise fabrication and positioning of physical features, we can 

integrate numerous different optoelectronic devices, which are fabricated on separate wafers from different 
semiconductor and related materials, matching the material to the function to create improved performance by using the 
highest performance elements of each type. For example, our hybrid integration allows us to integrate active devices, 
such as photodiodes or lasers fabricated using Indium Phosphide, with high-performance passive devices, such as 
interferometers, switches, routers and filters, fabricated on silicon, and to mate electronic amplifiers made with Silicon 
Germanium or drivers made with Gallium Arsenide directly to optical elements made with Silicon or Indium Phosphide.  

This ability to combine specific functional elements out of optimized materials not only allows for very compact 

and low power components, but also through the intimate coupling of different elements, makes possible completely new 
functions. An example of this multi-platform architecture is found in the coherent optical communications domain where 
we intimately couple a passive interferometer with separate quadrature components carrying information and with photo 
detectors to turn a high speed optical signal into data-rich electrical signals for processing.  

Optoelectronic engineering and integration. As we create complex integrated optoelectronic devices, we design 
and build electronic control algorithms and devices, signal processing methodologies, hardware and software routines 
and protocols, and device level ASICs that function to control and manage the highest performance features and 
capabilities of these integrated optoelectronics devices and systems. For example, our digital and analog modules are 
carefully characterized and controlled to extend and deliver their full operating ranges and performance features enables 
by their Advanced hybrid Photonic Integration platform. 

Hardware and firmware integration. We also sell our products as modules and subsystems which contain 
electronic hardware and firmware controls that interface directly with our customers’ systems. We design the electronic 
hardware and develop the firmware for control of our optical products and subsystems, and so that our optical products 
meet customer specifications.  

Devices, Components, Modules & Subsystems. We are vertically integrated from the design of photonic integrated 

devices through manufacturing in our own wafer fabs and assembly and test in our own factories. We design and 
manufacture modules and subsystems that combine our key products with other elements to offer customers a complete 
solution. We sell products at each level of product utility and can achieve the highest performance and capture the 
greatest value. We utilize some contract manufacturers for assembly operations where it is cost effective.  

Fabrication and manufacturing processes. We have developed expertise in the technology domains relevant to 

high-volume fabrication and manufacturing of our optoelectronic integrated circuit products using wafer-scale processes 
and including the complex interaction of electro-optic, thermal-optic and mechanical micro-thermal features. Our 
complex manufacturing steps are analogous to many processes used in the semiconductor industry. Each integrated 
element is tested and characterized using our proprietary test equipment before incorporation into our products. 
Moreover the ability to assemble complete optoelectronic devices, modules and systems with full control of performance 
and fabrication from the semiconductor and optical device level through to its optoelectronic controls to its pluggable 
module form factor enables delivery of the highest performance, highest scale and lowest cost solutions required by the 
industry. 

Circuit design and design-for-manufacturing tools. We use a comprehensive set of proprietary as well as industry 
standard software design tools, to model relevant geometries, dimensions and thermal management for a broad range of 
photonic devices. With these tools, we develop products with minimal design iterations and manage precision 
manufacturing to a narrow range of high performance specifications.  

13 

 
 
 
 
 
 
 
 
 
Our Products  

We develop and manufacture Transmitter Products, Receiver Products and Switch Products that are used in ultra-
high speed digital optical and signal processing communications, high speed switching and provisioning. We combine 
our transmitter and receiver products into Transceiver modules. Our Switching Products, such as Multi-Cast Switches, 
are used primarily in ROADM nodes that dynamically and efficiently allocate bandwidth to adjust for fast changing 
traffic patterns and for provisioning software defined optical networks. Our products can be categorized into groups, 
including High Speed Products for 100G, 200G, 400G and beyond applications, including in coherent networks, and 
Network Products and Solutions, for lower speed networks and other passive telecom and instrumentation products.  

High Speed Products: We produce transmitter and receiver products as well as switching products for 100G and 

beyond optical transmission applications over distances of 2 to 2,000 kilometers. In addition we combine 100G and 
beyond transmitter and receiver products into pluggable modules for both line side coherent and client side datacenter 
applications. All of our high speed 100G and beyond products are based on our Advanced Hybrid Photonic Integration 
technology. This technology supports encoding 100 gigabits or more per second of information for transmitting over a 
single channel and decoding the information at the receiver.  

For Long Haul and Metro transport, we design and manufacture optical components for coherent systems, which 

manipulate light to encode ten times or more the amount of information in the same wavelength channel than is possible 
with traditional methods. This manipulation can only be accomplished using advanced photonic integration to intimately 
couple functional elements together. Our Coherent Products include Ultra-Narrow Linewidth Tunable transmit and local 
oscillator lasers (NLW-TL), which generate the ultra-pure wavelength, or color, necessary for coherent transmission, and 
Integrated Coherent Receivers (ICRs), which decode the phase and polarization encoded coherent signal.  

We have introduced new pluggable coherent modules which combine our NLW-ITLA with our ICR and with our 

high performance coherent modulator such as in our CFP-DCO and CFP2-ACO transceiver and transponder optical 
modules.  The design for interoperability of each of the constituent elements of such a precise high speed device is a core 
capability that continues to fuel our ability to develop and deliver device and module products that achieve the highest 
performance available globally. 

We also sell 100G products for the client side and datacenter applications, including 25GBaud EMLs, laser 
drivers, modulator drivers and photodiode receivers for 100G and beyond client side applications.  We further offer our 
CFP2-LR4 and QSFP28-LR4 pluggable transceiver modules for high speed datacenter and telecom client applications.  

Further, we are developing 400G client side transceiver modules in a CFP8 configuration based on our leading 28 

Gbaud lasers at 50 Gbps using a PAM4 architecture.  Taking this development one step further, we will also expect to 
sell our ultra-high-speed 56 Gbaud EML and driver IC set to enable single wavelength PAM4 100G applications and 
subsequently four wavelength 400G intra-datacenter transmission.  

Also, for webscale datacenter applications we have introduced a series of high power laser diode array products for 
short reach Silicon Photonics based 100G intra-datacenter interconnections which use parallel single-mode architectures, 
or PSM4, as well as coarse wavelength division multiplexing, or CWDM architectures.  

We provide a proprietary switching solution for 100G coherent systems embodied in our Multi-Cast Switch (MCS) 
product line. Our 4x4, 4x16 and 8x16 Multi-Cast Switch modules for CDC ROADMs efficiently allocate bandwidth and 
signal routing in 100G and higher data rate networks. The Multi-Cast Switch provides scalable contentionless operation 
to achieve the highest traffic management efficiency, optimizing traffic flows in coherent transmission systems. Our 
MCS uses our PLC photonic integration platform and consists of a complex array of switches, waveguides, taps, 
crossings and other functional elements manufactured on Silicon wafers using standard semiconductor processing 
equipment.

Network Products and Solutions: We design and manufacture products for optical communications networks and a 
variety of other applications, where the networks operate at speeds less than 100G. We offer a wide range of application-
specific passive optical functionalities in modules or sub-system configurations. These include arrayed waveguide 
grating based drop modules for multiplexing and demultiplexing in conventional ROADM nodes as well as variable 
optical attenuators and tap power monitors for network monitoring and control. We combine several of these functions 
together in subsystems such as our variable multiplexer, which combines up to 48 variable optical attenuators and an 
arrayed waveguide grating multiplexer in a single compact unit.  In addition, many of these products provide high-
bandwidth connections to base station antennas for mobile devices and to people and machines over fixed and wireless 
networks. As consumer connectivity speeds have increased through the transitions from 2G to 3G to 4G/LTE, the 
bandwidths necessary to aggregate and connect wireless traffic into the backbone network, including Mobile 
BackHaul, have also increased. We offer 10G EMLs, laser drivers, modulator drivers and photodiode receivers for these 
applications.  

Through 2016 we also offered complete transceiver modules for a variety of low speed Access and Mobile 
Backhaul applications, including GPON and GEPON transceiver products at up to 10G data rates, plus 10G and below 
telecom, bidirectional and specialty transceiver products. Upon the sale of the Low Speed Transceiver Products’ assets to 
APAT OE in January 2017, these products will no longer be included in the Network Products and Solutions product 
group. 

In addition to products for fiber optic communications, we also sell products for test and measurement, 

instrumentation, industrial and research applications.

facilities, we conduct new product development, manufacturing and process engineering, quality control, continuous 
improvement and cost reduction relating to product manufacturing, assembly and test. In our Wuhan, China and Ottawa, 
Canada facilities we conduct new device, component and product development.  

We seek to establish and maintain proprietary rights in our technology and products through the use of patents, 

copyrights and trade secret laws. We have filed applications for patents to protect certain of our intellectual property in 
the U.S. and in other countries, including Australia, Canada, Japan, Korea, Hong Kong, China, Russia, India, Taiwan 
and several European Union countries. As of December 31, 2016, we had approximately 650 issued patents, expiring 
between 2017 and 2034 covering various aspects of our technologies.  

We have manufacturing operations in the U.S., Japan, China and Russia. Our wafer fabrication operations are 
located in our San Jose and Fremont, California facilities, as well as in our Japan facilities, and include chip design, clean 
room fabrication, integration and related facilities for PICs. Our manufacturing, assembly and test operations are located 
in our Shenzhen and Dongguan, China facilities, and in Silicon Valley, California. In addition, we have established

As of December 31, 2016, we had 2,401 employees and non-employee contractors, of which 310 were based in the 

U.S., 1,913 in China, 117 in Japan, 52 in Russia and Europe and 9 in Canada. 

None of our U.S. employees are represented by a labor union. Chinese law allows that all employees be members 

of a union that is overseen by the Chinese government. The majority of the employees in our Japanese subsidiary are 
also members of a union. We have never experienced employment-related work stoppages and we consider our 
employee relations to be good. 

Our Customers 

In 2016, 2015 and 2014, our ten largest customers accounted for 91%, 91% and 88% of our total revenue, 

respectively. In 2016, customers of 10% or more revenue were Huawei, together with its affiliate HiSilicon Technologies 
Co. Ltd. (collectively “Huawei”), and Ciena Corporation, which accounted for 50% and 15% of our total revenue, 
respectively. In 2015, Huawei and Ciena Corporation accounted for 44% and 21% of our total revenue, respectively. In 
2014, Huawei, Ciena Corporation, and Alcatel-Lucent SA accounted for 38%, 15% and 10% of our total revenue, 
respectively.  

Our Sales and Marketing  

We operate a sales model that focuses on alignment with our customers through coordination of our sales, product 

application engineering and manufacturing teams. Our sales cycles typically require a significant amount of time and a 
substantial expenditure of resources before we can realize revenue from the sale of products. The length of our sales 
cycle, from initial request to design win, is typically 6 to 12 months for an existing product and 12 to 18 months or 
longer for a new product.  

We use a global direct sales force based in North America, Europe, Russia and Asia, including China and Japan. 

These individuals work with our product application engineers, and product marketing and sales operations teams, in an 
integrated approach to address our customers’ current and future needs. We have very deep technical relationships.  We 
believe that these collaborative engineering activities provide us insight into our customers’ broader and longer-term 
needs. We view our technical sales capability and our technical relationships with customers as a key part of our value 
delivery to our key strategic customers. 

Our marketing team focuses on product strategy, product development, roadmap development, new product 

introduction processes, program management, product demand stimulation and assessment, and competitive analysis. 
Our marketing team also seeks to educate the market about our products by communicating the value proposition and 
product differentiation in direct customer interactions and presentations and at industry tradeshows and at technical 
conferences. It is important that these teams are engaged in both industry forums such as MSA, Committees, etc. as well 
as direct customer and end-user engagements.

digital optics, hybrid optical integration, optoelectronics control and in signal processing. 

Our Suppliers 

We use suppliers from the U.S., China, Japan and other locations. Although there are multiple sources for most of 
the component parts of our products, some components are sourced from single or, in some cases, limited sources, which 
can increase risks of materials availability for production. We typically do not have written agreements with the majority 
of these component manufacturers to guarantee the supply of the key components used in our products. We also use 
contract manufacturers in Japan, China and other Asia locations for the back-end manufacturing of certain of our 
products.  

As the industry scales the entire supply chain is working to scale.  As a result we work closely with our key 

suppliers to understand their business as we grow together.  This requires our continuing close management. 

Our Backlog  

Sales of our products generally are made pursuant to purchase orders, often with short lead times. These purchase 

orders are typically made without deposits and may be subject to revision or cancellation. The quantities actually 
purchased by our customers, as well as the shipment schedules, are frequently revised to reflect changes in our 
customers’ needs and in our supply of products.  

Certain of our customers use vendor managed inventory (VMI) arrangements under which we manufacture at a 
customer’s request, then ship to its facility or a designated contract manufacturer for the customer, to be held until it is 
used by the customer. We maintain title to vendor managed inventory until the customer uses the inventory. At that time 
the customer takes title to the products, it reports the consumption to us and we recognize the revenue for the product 
sale. The increased use of VMI by our customers may increase the possibility of changes to our backlog since customers 
may consume VMI more quickly or more slowly than we had planned.  

Our direct sales force works our customers in an integrated approach to understand current and future needs.  

Because we operate a sales model that focuses on alignment with our customers there is the possibility of changes in 
delivery or acceptance schedules, cancellations, modifications or price reductions with limited or no penalties and the use 
by customers of VMI is increasing, we do not believe that backlog is a firm or reliable indicator of our future revenue 
and do not rely on backlog to manage our business or evaluate our performance. Changes in the amount of our backlog 
do not necessarily reflect a corresponding change in the level of actual or potential sales.  

Seasonality 

Historically, our first quarter revenue is generally seasonally lower than the rest of the year primarily due to lower 
capacity utilization during the holidays in China and the impact of typical price negotiations conducted at the end of each 
calendar year and impacting shipments during this period. This historical pattern is important in recognizing the typical 
annual distribution of revenue from quarter to quarter through the year.  That said, it varies markedly year to year so 
should not be considered a reliable indicator of our future revenue or financial performance.

Financial Information by Geographic Region  

For information regarding our revenue and property, plant and equipment by geographic region, see Note 16 to the 

Consolidated Financial Statements. For risks relating to our operations see “Item 1A. Risk Factors” and particularly the 
risks under the caption “Risks related to our operations in China” and the risk factors “Our future results of operations 
may be subject to volatility as a result of exposure to fluctuations in foreign exchange rates, primarily the Chinese 
Renminbi (RMB) and Japanese Yen (JPY) exchange rates”, “We face a variety of risks associated with international 
sales and operations, which if not adequately managed could adversely affect our business and financial results” and 
“We are subject to global governmental export and import controls that could subject us to liability, impair our ability to 
compete in international markets or restrict our sales to certain customers”.  

Competition  

The market for optical communications systems is highly competitive. While no single company competes with us 

across all of our product areas, our competitors range from large international companies offering a wide range of 
products to smaller companies specializing in narrow markets. We believe the principal competitive factors in this 
market are:  

• 

• 

• 

• 

• 

• 

• 

• 

• 

ability to provide leading edge technologies for high speed communications;  

ability to design and manufacture high quality, reliable products, including customized solutions;  

breadth of product solutions;  

price to performance characteristics;  

financial stability;  

ability to quickly and consistently produce in high volume and high quality;  

ability to meet customers’ specific requirements;  

ability to meet customer lead time demands; and  

depth of relationships with and proximity to key customers globally.  

We believe we compete favorably with respect to these factors. We believe our principal competitors include: 

•  Furukawa Co., Ltd., Fujitsu Optical Components Limited, NTT Electronics Corporation, Oclaro, Inc., 

Sumitomo, Finisar, Lumentum Holdings Inc. (formerly JDS Uniphase Corporation) and others in Coherent 
products; 

•  Accelink Technologies Co., Ltd., Broadcom (formerly Avago), Finisar, InnoLight Technology Corporation, 
M/A-Com, Inc, Oclaro, Source Photonics, Inc., Sumitomo and others in Datacenter and Client side products; 

•  Lumentum and NTT Electronics Corporation in switching; and 

•  Lumentum, NTT Electronics Corporation, M/A-Com, Inc., Oclaro, Inc., Sumitomo and others in Network 

Products and Solutions. 

Our competitors may have substantially greater name recognition and technical, financial and marketing resources 

than we do. Many of our competitors have greater resources to develop products or pursue acquisitions, and more 
experience in developing or acquiring new products and technologies and in creating market awareness for these 
products and technologies than we do. In addition, a number of our competitors have the financial resources to offer 

18 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
competitive products at below market pricing levels that could prevent us from competing effectively and which could 
adversely affect our financial performance.  

We also face competition from some of our customers, including Huawei and its affiliate, HiSilicon, who evaluate 

our capabilities against the merits of manufacturing products internally. These customers may have the ability to 
manufacture competitive products at a lower cost than we would charge as a result of their higher levels of integration. 
As a result, these customers may purchase less of our products and there would be additional pressure to lower our 
selling prices which, accordingly, would negatively impact our revenue and gross margin.  

Environmental, Health and Safety Matters  

Our research and development and manufacturing operations and our products are subject to a variety of 

environmental, health and safety laws and regulations in the jurisdictions in which we operate. These regulations govern, 
among other things, the discharge of pollutants to air, water, and soil; the remediation of soil and groundwater 
contamination; the use, handling and disposal of hazardous materials; employee health and safety; and the hazardous 
material content and recycling of our products. We use, store and dispose of hazardous materials in our manufacturing 
operations and as components in our products. We incur costs to comply with existing environmental, health and safety 
requirements, and any failure to comply, or the identification of contamination for which we are found liable, could 
cause us to incur additional costs, including cleanup costs, monetary fines, or civil or criminal penalties, or result in the 
curtailment of our operations. In addition, environmental, health and safety requirements have become more stringent 
over time, and changes to existing requirements could restrict our ability to expand our facilities, require us to acquire 
costly pollution control equipment, or cause us to incur other significant expenses or to modify our manufacturing 
processes or the contents of our products. Some jurisdictions in which we operate or sell our products have enacted 
requirements regarding the recycling of waste electronic equipment, and/or the packaging and hazardous material 
content of certain products. For example, jurisdictions including China and the European Union, among a growing 
number of jurisdictions, have placed restrictions on the use of lead, among other chemicals, in electronic products, which 
affects the composition and packaging of our products. The passage of such requirements in additional jurisdictions, or 
the tightening of standards or elimination of certain exemptions in jurisdictions where our products are already subject to 
such requirements, could cause us to incur significant expenditures to make our products compliant with new 
requirements, or could limit the markets into which we may sell our products.  

Additionally, increasing efforts to control emissions of greenhouse gases, or GHG, may also impact us. For 
example, our semiconductor manufacturing operations in California use perfluorocarbons, which are classified as a high 
global warming potential greenhouse gas. Under California’s Global Warming Solutions Act, we designed and installed 
additional pollution control equipment at our San Jose, California, manufacturing plant to reduce our perfluorocarbon 
emissions beginning in 2012. Since the end of 2012, our San Jose and Fremont, California, manufacturing facilities have 
maintained compliance with the Global Warming Solutions Act through the monitoring and reviewing of our 
Greenhouse Gas Emissions including permits issued locally by the Bay Area Air Quality Management District 
(BAAQMD), and we have submitted reports annually to verify such compliance. In the U.S., the Environmental 
Protection Agency has announced a finding relating to GHG emissions that may result in promulgation of federal GHG 
air quality standards that could also affect us.

ITEM 1A.  RISK FACTORS  

Risks Associated with Our Business 

We are dependent on Huawei Technologies Co., Ltd. and its affiliate HiSilicon Technologies Co., Ltd., Ciena, Nokia 
and our other key customers for a large portion of our revenue and the loss of, or a significant reduction in orders in 
any period from any of our major customers may reduce our revenue and adversely impact our results of operations. 

We have generated most of our revenue from a limited number of customers. In the year ended December 31, 

2016, Huawei Technologies, together with its affiliate HiSilicon (or collectively, Huawei), and Ciena Corporation 
accounted for approximately 50% and 15% of our revenue, respectively, and our top ten customers represented 91% of 
our revenue. In the year ended December 31, 2015, Huawei and Ciena accounted for approximately 44% and 21% of our 
revenue, respectively, and our top ten customers represented 91% of our revenue. In the year ended December 31, 2014, 
Huawei, Ciena, and Nokia Corporation accounted for 38%, 15% and 10% of our revenue, respectively, and our top ten 
customers represented 88% of our revenue. The loss of, or a significant reduction in orders from these major customers 
or any of our other key customers would materially and adversely affect our revenue and results of operations.  

Manufacturing problems could impact manufacturing yields or result in delays in product shipments to customers 
and could adversely affect our revenue, competitive position and reputation. 

We may experience delays, disruptions or quality control problems in our manufacturing operations or supply 

chain constraints, which could adversely impact manufacturing volumes, yields or delay product shipments. As a result, 
we could incur additional costs that would adversely affect our gross margin, and product shipments to our customers 
could be delayed beyond the shipment schedules requested by our customers, which would negatively affect our revenue, 
competitive position and reputation. 

Additionally, manufacturing yields depend on a number of factors, including the stability and manufacturability of 

the product design, manufacturing improvements gained over cumulative production volumes, the quality and 
consistency of component parts and the nature and extent of customization requirements by customers. Capacity 
constraints, raw materials shortages, logistics issues, labor shortages, volatility in utilization of manufacturing 
operations, supporting utility services and other manufacturing supplies, the introduction of new product lines, rapid 
increases in production demands and changes in customer requirements, manufacturing facilities or processes, or those 
of some third party contract manufacturers and suppliers of raw materials and components have historically caused, and 
may in the future cause, reduced manufacturing yields, negatively impacting the gross margin on, and our production 
capacity for, those products. Our ability to maintain sufficient manufacturing yields is particularly challenging with 
respect to PICs due to the complexity and required precision of a large number of unique manufacturing process steps. 
Manufacturing yields for PICs can also suffer if contaminated materials or materials that do not meet highly precise 
composition requirements are inadvertently utilized. Because a large portion of our PIC manufacturing costs are fixed, 
PIC manufacturing yields have a substantial effect on our gross margin. Lower than expected manufacturing yields could 
also delay product shipments and decrease our revenue.  

We depend upon outside contract manufacturers for a portion of the manufacturing process for some of our 
products. Our operations and revenue related to these products could be adversely affected if we encounter problems 
with a contract manufacturer. 

The majority of our products are manufactured internally. However, we also rely upon contract manufacturers in 
Thailand, China, Japan and other Asia locations to provide back-end manufacturing and produce the finished portion of 
some of our products. Our reliance on contract manufacturers for these products makes us vulnerable to possible capacity 
constraints and reduced control over their supply chains, delivery schedules, manufacturing yields, manufacturing 
quality/controls and costs. If one of our contract manufacturers is unable to meet all of our customer demand in a timely 
fashion, whether due to their direct operating control or due to their supply chain, this could have a material adverse 
effect on the revenue from our products. 

20 

 
 
We are subject to risks and uncertainties related to our revenue growth outlook in China. 

Fiber optics telecommunication growth in China is an important contributor to our success. We expect a major 
portion of our revenue growth to come from China infrastructure spending in wireline and wireless networks, notably 
from the three largest China telecom carriers, China Mobile Communications Corporation, China Telecommunications 
Corporation and China United Network Communications Group Co., Ltd. In part, this infrastructure spending originates 
from the publicly announced China Broadband 2020 National Initiative. If the anticipated Chinese spending and carrier 
large tender awards do not materialize as anticipated, or if there are unanticipated delays in the Chinese initiative, our 
business, financial condition, results of operations and prospects would be adversely affected. 

We are under continuous pressure to reduce the prices of our products, which has adversely affected, and may 
continue to adversely affect, our gross margins. 

The communications networks industry has been characterized by declining product prices over time as 
technological advances increase price and performance and put pressure on existing products. We have reduced the 
prices of many of our products in the past, most often during annual end-of-year price negotiation. We expect pricing 
pressure for our products to continue, including from our major customers. To maintain or increase their market share, 
our competitors also reduce prices of their products each year. In addition, our customers may seek to internally develop 
and manufacture competing products at a lower cost than we would otherwise charge, which would add additional 
pressure on us to lower our selling prices. If we are unable to offset any future reductions in our average selling prices by 
increasing our sales volume, reducing our costs or introducing new products, our gross margin would be adversely 
affected. 

If the Metro and datacenter interconnect market sectors do not grow as rapidly as we expect, or if demand for our 
products in these sectors is lower than we expect, our revenue growth may be adversely affected. 

We expect that our future growth in the market for 100G and beyond coherent products to be driven in large part 

by the increased adoption of our products in the Metro market segment and in the high-performance datacenter 
interconnect market. Over the last several years, 100G and beyond coherent technology has seen increasing adoption in 
the Long Haul market segment and now is penetrating the much larger Metro sector of the market. 

If we fail to achieve or sustain a leadership position in the Long Haul telecom sector and use our position in that 

market to penetrate the Metro and datacenter interconnect segments, if these segments fail to grow as expected, or if 
demand for our products in the Metro and datacenter interconnect market segments fails to materialize, our business, 
financial condition, results of operations and prospects would suffer. 

We face intense competition which could negatively impact our results of operations and market share. 

The communications networks industry is highly competitive. Our competitors range from large international 

companies offering a wide range of products to smaller companies specializing in niche products.  

Some of our competitors have substantially greater name recognition, technical, financial, and marketing 
resources, and greater manufacturing capacity, as well as better-established relationships with customers, than we do. 
Some of our competitors have more resources to develop or acquire, and more experience in developing or acquiring, 
new products and technologies. Some of our competitors may be able to develop new products more quickly than us and 
may be able to develop products that are more reliable or which provide more functionality than ours. In addition, some 
of our competitors have the financial resources to offer competitive products at below-market pricing levels that could 
prevent us from competing effectively and result in a loss of sales or market share or cause us to lower prices for our 
products. 

We also face competition from some of our customers who evaluate our capabilities against the merits of 
manufacturing products internally, including Huawei. Due to the fact that such customers are not seeking to make a 
comparable profit directly from the manufacture of these products, they may have the ability to provide competitive 
products at a lower total cost than we would charge such customers. As a result, these customers may purchase less of 

21 

 
our products and there would be additional pressure to lower our selling prices which, accordingly, would negatively 
impact our revenue and gross margin. 

If we fail to retain our key personnel or if we fail to attract additional qualified personnel, we may not be able to 
achieve our anticipated growth and our business could suffer.  

Our success and ability to implement our business strategy depends upon the continued contributions of our senior 

management team and others, including senior management in foreign subsidiaries and our technical and operations 
employees in all locations. Our future success depends, in part, on our ability to attract and retain key personnel, 
including our senior management and others. The loss of services of members of our senior management team or key 
personnel or the inability to continue to attract and retain qualified personnel could have a material adverse effect on our 
business. Competition for highly skilled technical and operations people where we operate is extremely intense, and we 
continue to face challenges identifying, hiring and retaining qualified personnel in many areas of our business. 

Customer demand is difficult to accurately forecast and, as a result, we may be unable to optimally match production 
with customer demand. 

We make planning and spending decisions based on our estimates of customer requirements. The short-term 

nature of commitments by many of our customers, and the possibility of unexpected changes in demand for their 
products, reduce our ability to accurately estimate future customer requirements. On occasion, customers may require 
rapid increases in production, which can strain our resources, cause our manufacturing to be negatively impacted by 
materials shortages, necessitate higher or more restrictive procurement commitments, increase our manufacturing yield 
loss and scrapping of excess materials, result in delayed shipments and/or reduce our gross margins. We may not have 
sufficient capacity at any given time to meet the volume demands of our customers, and we may have difficulty 
expanding our manufacturing operations on a timely basis to meet increasing customer demand. Additionally, one or 
more of our suppliers may not have sufficient capacity at any given time to meet our volume demands. Because many of 
our costs and operating expenses are relatively fixed, reduction in customer demand due to market downturns or other 
reasons would have a material adverse effect on our operating results.  

We have had a history of losses which may recur in the future. 

We have had a history of losses and we may incur additional losses in future periods. As of December 31, 2016, 
our accumulated deficit was $298.7 million. We also expect to continue to make significant expenditures related to the 
ongoing operation and development of our business. These include expenditures related to the sales, marketing and 
development of our products and to maintain our manufacturing facilities and research and development operations. 

The majority of our customer contracts do not commit customers to specified buying levels, and many of our 
customers may decrease, cancel or delay their buying levels at any time with little or no advance notice to us. 

Our products are typically sold pursuant to individual purchase orders or by use of a vendor-managed inventory, or 

VMI, model, which is a process by which we ship agreed quantities of products to a customer-designated location and 
those products remain our inventory and we retain the title and risk of loss for those products until the customer takes 
possession of the products. Our customers are typically not contractually committed to buy any quantity of products 
beyond firm purchase orders. Many of our customers may increase, decrease, cancel or delay purchase orders already in 
place. We have experienced and expect to continue to experience wide fluctuations in demand from customers using 
VMI, particularly Huawei Technologies Co., Ltd. and their affiliate HiSilicon Technologies Co., Ltd., even in instances 
where we have built and shipped products to the customer-designated locations as VMI.  

If we fail to adequately manage our growth and expansion, our business and financial results will suffer. 

In recent years, we have experienced significant growth through, among other things, internal manufacturing and 

related expansion programs, product development and acquisitions of other businesses and products. Our business has 
expanded to numerous locations, including foreign locations, and as a result has become more complex, more demanding 

22 

 
of management’s attention and subject to new laws and regulations.  

Our success and ability to further scale our business will depend, in part, on our ability to manage changes in a 
cost-effective and efficient manner. If we cannot manage our growth, we may be unable to take advantage of market 
opportunities, execute our business strategies or respond to competitive pressures. Any failure to effectively manage 
growth, maintain our quality and/or or customer satisfaction could adversely affect our business and reputation. 

Our success will depend on our ability to anticipate and quickly respond to evolving technologies and customer 
requirements. 

Our ability to anticipate and respond to evolving technology, industry standards, customer requirements and 
product offerings, and to develop and introduce new and enhanced products and technologies, will be critical factors in 
our ability to succeed. In addition, the introduction of new products by other companies embodying new technologies, or 
the emergence of new industry standards, could render our existing products uncompetitive from a pricing standpoint, 
obsolete or otherwise unmarketable. 

While we rely on many suppliers, there are a few which, if they stopped, decreased or delayed shipments to us, it could 
have an adverse effect on our business and financial results. 

We depend on a limited number of suppliers for certain components and materials we have qualified to use in the 
manufacture of certain of our products. Some of these suppliers could disrupt our business if they stop, decrease or delay 
shipments or if the components they ship have quality, consistency, or business continuity issues. Some of these 
components and materials are available only from a sole source, or have been qualified only from a single source. We 
may also face component shortages if we experience increased demand for components beyond what our qualified 
suppliers can deliver. If we experience component shortages from certain key suppliers, we may be unable to meet 
customer demand or may have higher purchasing costs, or both. Although we engage in various actions to mitigate the 
impact of these shortages, any inability on our part to obtain sufficient quantities of critical components at reasonable 
costs could adversely affect our ability to meet demand for our products, which could cause our revenue, results of 
operations, or both to suffer. 

Our customers generally restrict our ability to change the component parts in our modules without their approval 

and such changes may require repeating product qualification processes. The reliance on a sole supplier, single qualified 
vendor or limited number of suppliers could result in delivery and quality problems, reduced control over product 
pricing, reliability and performance and an inability to identify and qualify another supplier in a timely manner. Any 
supply deficiencies relating to the quality, quantities or timeliness of delivery of components that we use to manufacture 
our products could adversely affect our ability to fulfill our customer orders and our results of operations. 

We must continually achieve new design wins and enhance existing products or our business and future revenue may 
be harmed. 

The markets for our products are characterized by frequent new product introductions, changes in customer 

requirements and evolving industry standards, all with an underlying pressure to reduce cost and meet stringent 
reliability and qualification requirements. Our future performance will depend on our successful development, 
introduction and market acceptance of new and enhanced products that address these challenges. The anticipated or 
actual introduction of new and enhanced products by us and by our competitors may cause our customers to defer or 
cancel orders for our existing products, and could result, and in the past, has resulted, in a write-down in the value of 
inventory. To the extent customers defer or cancel orders for our products for any reason or we fail to achieve new 
design wins, our competitive position would be adversely affected and our ability to grow revenue would be impaired. 

Furthermore, fast time-to-market with new products can be critical to success in our markets. It is difficult to 

displace an existing supplier for a particular type of product once a network equipment vendor has chosen a supplier, 
even if a later-to-market product provides superior performance or cost efficiency. If we are unable to make our new or 
enhanced products commercially available on a timely basis, we may lose existing and potential customers and our 
financial results would suffer. 

23 

 
We may be exposed to costs or losses from product lines that we intend to exit or may undertake divestiture of portions 
of our business that require us to continue providing substantial post-divestiture transition services and support, 
which may cause us to incur unanticipated costs and liabilities and adversely affect our financial condition and 
results of operations.  

In August 2016, we announced our intention to reduce the volume and end the production of certain of our lower-

margin laser and PON products within a year of August 2016. In January 2017, we completed the sale of assets and 
transfer of certain liabilities of our access network and low speed transceiver product lines (the “Low Speed Transceiver 
Products”). The foregoing actions are part of our strategy to exit products that have been declining in revenue and have 
lower gross margins than our other higher speed products. We may incur additional costs in connection with the sale or 
end-of-life of these products, or other products and/or facilities in the future, and our revenues and net income could be 
negatively affected, particularly in the short term, in connection with the end-of-life or sales of such products and/or 
facilities.  It is also possible that we could incur continued costs or liabilities after the end-of-life process is completed, 
which could have a material adverse effect on our financial condition or operating results. 

We are subject to the cyclical nature of the markets in which we compete and any future downturn may reduce 
demand for our products and revenue. 

The markets in which we compete are tied to the aggregate capital expenditures of telecommunications service 
providers as they build out and upgrade their network infrastructure. These markets may be cyclical and characterized by 
rapid technological change, price erosion, evolving standards and wide fluctuations in product supply and demand. In the 
past, including recently to varying degrees in China, the U.S. and Europe, these markets have experienced significant 
downturns, often connected with, or in anticipation of, the maturation of product cycles—for both manufacturers’ and 
their customers’ products—or in response to over or under purchasing of inventory by our customers relative to ultimate 
carrier demand, and with declining general economic conditions. These downturns have been characterized by 
diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling 
prices.   

Our historical results of operations have been subject to substantial fluctuations, and we may experience 

substantial period-to-period fluctuations in future results of operations.  

If spending for communications networks does not continue to grow as expected, our business and financial results 
may suffer. 

Our future success as a provider of modules and subsystems to leading network equipment vendors depends on 
continued capital spending on global communications networks. Network traffic has experienced rapid growth driven 
primarily by bandwidth-intensive content, including cloud services, mobile video and data services, wireless 4G/LTE 
and 5G services, social networking, video conferencing and other multimedia. This growth is intensified by the 
proliferation of fixed and wireless devices that are enabling consumers to access content at increasing data rates anytime 
and anywhere. Our future success depends on continued demand for high-bandwidth, high-speed communications 
networks and the ability of network equipment vendors and carrier datacenter operators to fulfill this demand. 

We face a variety of risks associated with international sales and operations, which if not adequately managed could 
adversely affect our business and financial results. 

We derive, and expect to continue to derive, a significant portion of our revenue from international sales in various 

markets. In addition, a major portion of our operations is based in Shenzhen and Dongguan, China and we have 
additional operations in Japan, Russia and Canada. Our international revenue and operations are subject to a number of 
material risks, including, but not limited to: 

•  difficulties in staffing, managing and supporting operations in more than one country; 

•  difficulties in enforcing agreements and collecting receivables through foreign legal systems; 

•  fewer legal protections for intellectual property in foreign jurisdictions; 

24 

 
•  the need for compliance with local laws and regulations; 

•  foreign and U.S. taxation issues and international trade barriers; 

•  general economic and political conditions in the markets in which we operate; 

•  difficulties in obtaining any necessary governmental authorizations for the export of our products to certain 

foreign jurisdictions; 

•  imposition of export restrictions on sales to any of our major foreign customers; 

•  fluctuations in foreign economies and fluctuations in the value of foreign currencies and interest rates; 

•  trade and travel restrictions; 

•  outbreaks of contagious disease; 

•  domestic and international economic or political changes, hostilities and other disruptions; and 

•  difficulties and increased expenses in complying with a variety of U.S. and foreign laws, regulations and trade 

standards, including the Foreign Corrupt Practices Act and international labor standards. Negative 
developments in any of these areas in China, Japan, Russia or other countries could result in a reduction in 
demand for our products, the cancellation or delay of orders already placed, difficulties in producing and 
delivering our products, threats to our intellectual property, difficulty in collecting receivables, higher labor 
costs and a higher cost of doing business. 

In addition, although we maintain an anti-corruption compliance program throughout our company, violations of 
our compliance program may result in criminal or civil sanctions, including material monetary fines, penalties and other 
costs against us or our employees, and may have a material adverse effect on our business.  

Failure to realize the anticipated benefits from our planned expansion in the Russian Federation may affect our 
future results of operations and financial condition. 

In connection with our raising capital in an April 2012 private placement of common stock, we have established a 
wholly-owned subsidiary and company operations in the Russian Federation. The establishment of successful operations 
in the Russian Federation requires capital expenditure over several years, and is in part dependent on the cooperation of 
Russian entities that could include the Russia government and other third parties. If there are delays in our efforts to 
establish and maintain operations in the Russian Federation, the anticipated benefits of our Russian expansion may not 
be realized or may take longer to realize than expected. We could be required to pay up to $3.5 million to Joint Stock 
Company “RUSNANO” (formerly Open Joint Stock Company “RUSNANO”), or Rusnano, if we do not meet certain 
investment conditions towards our Russian operations by 2019.  

Our business operations conducted in Russia are relatively small compared to our overall business. However, we 

are subject to economic, political, legal, and social events and developments in Russia, including but not limited to 
actions such as restrictions placed on U.S. companies doing business in Russia. 

Our revenues and costs will fluctuate over time, making it difficult to predict our future results of operations.   

Our revenue, gross margin and results of operations have varied significantly and are likely to continue to vary 
from quarter to quarter due to a number of factors, many of which are not within our control. For instance, changes in 
gross margin may result from various factors, such as changes in pricing, changes in our fixed costs, changes in the cost 
of labor, changes in the mix of our products sold, changes in the amount of product manufactured versus the amount of 
product sold over time, and charges for excess and obsolete inventory. In addition, our first quarter revenue is generally 
seasonally lower than the rest of the year primarily due to lower capacity utilization during the holidays in China and the 
impact of typical price negotiations during the fourth quarter. It is difficult for us to accurately forecast our future 
revenue and gross margin and plan expenses accordingly and, therefore, it is difficult for us to predict our future results 
of operations.

Increasing costs and other factors may adversely impact our gross margins. 

We may not be able to maintain or improve our gross margins because of slow introductions of new products, 
pricing pressure from increased competition, failure to effectively reduce the cost of existing products, failure to improve 
our product mix, future macroeconomic or market volatility reducing sales volumes, changes in customer demand 
(including a change in product mix among different areas of our business) or other factors. Our gross margins can also be 
adversely affected for reasons including, but not limited to, fixed manufacturing costs that would not be expected to 
decrease in proportion to any decrease in revenues; unfavorable production yields or variances; increases in costs of 
input parts and materials; the timing of movements in our inventory balances; warranty costs and related returns; changes 
in foreign currency exchange rates; possible exposure to inventory valuation reserves; and other increases in our costs 
and expenses, including as a result of rising labor costs in China. Such significant increases in costs without 
corresponding increases in revenue would materially and adversely affect our business, our results of operations and our 
financial condition and our gross margins.  

We may not be able to obtain capital when desired on favorable terms, if at all, or without dilution to our 
stockholders. 

We believe that our existing cash and cash equivalents, and cash flows from our operating activities and funds 

available under our credit facilities, will be sufficient to meet our anticipated cash needs for at least the next 12 months. 
We operate in an industry, however, that makes our prospects difficult to evaluate. It is possible that we may not 
generate sufficient cash flow from operations or otherwise have the capital resources to meet our future capital needs. If 
this occurs, we may need additional financing to continue operations or execute on our current or future business 
strategies, including to: 

•  invest in our research and development efforts, including by hiring additional technical and other personnel; 

•  maintain and expand our operating or manufacturing infrastructure; 

•  acquire complementary businesses, products, services or technologies; or 

•  otherwise pursue our strategic plans and respond to competitive pressures. 

If we raise additional funds an equity financing, the percentage ownership of our stockholders could be 
significantly diluted. In addition, a portion of our cash, cash equivalents and restricted cash is held by our subsidiaries 
outside of the U.S. and we may not be able to repatriate off-shore cash to the U.S. without taxes that may be substantial.  

If we incur additional indebtedness through arrangements such as credit agreements or term loans, such 

arrangements may impose restrictions and covenants that limit our ability to respond appropriately to market conditions, 
make capital investments or take advantage of business opportunities. In addition, any additional debt arrangements we 
may enter into would likely require us to make regular interest payments, which could adversely affect our results of 
operations. 

If our customers do not qualify our products for use, then our results of operations may suffer. 

Prior to placing volume purchase orders with us, most of our customers require us to obtain their approval—called 

qualification in our industry—of our new and existing products, and our customers often audit our manufacturing 
facilities and perform other vendor evaluations during this process. The qualification process involves product sampling 
and reliability testing and collaboration with our product management and engineering teams in the design and 
manufacturing stages. If we are unable to qualify our products with customers, then our revenue would be lower than 
expected and we may not be able to recover the costs associated with the qualification process which would have an 
adverse effect on our results of operations. 

In addition, due to evolving technological changes in our markets, a customer may cancel or modify a design 
project before we have qualified our product or begun volume manufacturing of a qualified product. It is unlikely that we 
would be able to recover the expenses for cancelled or unutilized custom design projects.  

26 

 
We have pursued and may continue to pursue acquisitions. Acquisitions could be difficult to integrate, divert the 
attention of key personnel, disrupt our business, dilute stockholder value and impair our financial results. 

As part of our business strategy, we have pursued and intend to continue to pursue acquisitions of complementary 

businesses, products, services or technologies that we believe could accelerate our ability to compete in our existing 
markets or allow us to enter new markets. Any of these transactions could be material to our financial condition and 
results of operations. For instance, in October 2011, we completed the acquisition of Santur Corporation, a designer and 
manufacturer of InP-based PIC products, and in March 2013 we completed the acquisition of the optical semiconductor 
business unit of LAPIS Semiconductor Co., Ltd., now known as NeoPhotonics Semiconductor. We purchased the 
tunable laser product lines of EMCORE in January 2015 and the power monitoring products business of EigenLight 
Corporation, or Eigenlight, in November 2015.  

Acquisitions involve numerous risks. The failure to successfully evaluate and execute acquisitions or otherwise 

adequately address such risks could result in excess costs and materially harm our business and financial results. 

Acquisitions also frequently result in the recording of goodwill and other intangible assets which are subject to 

potential impairments which have occurred in the past and which, were they to occur in the future, could harm our 
financial results.  

It could be discovered that our products contain defects that may cause us to incur significant costs, divert our 
attention, result in a loss of customers and result in product liability claims. 

Our products are complex and undergo quality testing as well as formal qualification, both by our customers and 
by us. For various reasons, such as the occurrence of performance problems that are unforeseeable in testing or that are 
detected only when products age or are operated under peak stress conditions, our products may fail to perform as 
expected long after customer acceptance. Failures could result from faulty components or design, problems in 
manufacturing or other unforeseen reasons. As a result, we could incur significant costs to repair or replace defective 
products under warranty, particularly when such failures occur in installed systems. Any significant product failure could 
result in lost future sales of the affected product and other products, as well as customer relations problems and litigation, 
which could harm our business. 

The communications networks industry has long product development cycles requiring us to incur product 
development costs without assurances of an acceptable investment return. 

Large volumes of communications equipment and support structures are installed with considerable expenditures 

of funds and other resources, and long investment return period expectations. At the component supplier level, these 
cycles create considerable, typically multi-year, gaps between the commencement of new product development and 
volume purchases. Due to changing industry and customer requirements, we are constantly developing new products, 
including seeking to further integrate functions on PICs and developing and using new technologies in our products. 
These development activities necessitate significant investment of capital. Our new products often require a long time to 
develop because of their complexity and rigorous testing and qualification requirements. Accordingly, we and our 
competitors often incur significant research and development and sales and marketing costs for products that, initially, 
will be purchased by our customers long after much of the cost is incurred and, in some cases, may never be purchased 
due to changes in industry or customer requirements in the interim. 

We are subject to global governmental export and import controls that could subject us to liability, impair our ability 
to compete in international markets, or restrict our sales to certain customers. 

We are subject to export and import control laws, trade regulations and other trade requirements that limit which 
products we sell and where and to whom we sell our products, especially laser-dependent products. In some cases, it is 
possible that export licenses would be required from the U.S. or other government agencies outside the U.S. such as, but 
not limited to, Japan, China or Russia for some of our products in accordance with various statutes. In addition, various 
countries regulate the export or import of certain technologies and have enacted laws that could limit our ability to 
distribute our products. Failure to comply with these and similar laws on a timely basis, or at all, or any limitation on our 

27 

 
ability to export or sell our products or to obtain any required licenses would adversely affect our business, financial 
condition and results of operations. 

If we fail to protect our intellectual property and other proprietary rights, our business and results of operations could 
be materially harmed. 

Our success depends to a significant degree on our ability to protect our intellectual property and other proprietary 

rights. We rely on a combination of patent, trademark, copyright, trade secret and unfair competition laws, as well as 
license agreements and other contractual provisions, to establish and protect our intellectual property and other 
proprietary rights. We have applied for patent registrations in the U.S. and in other foreign countries, some of which 
have been issued. We cannot guarantee that our pending applications will be approved by the applicable governmental 
authorities. 

Policing unauthorized use of our technology is difficult and we cannot be certain that the steps we have taken will 
prevent the misappropriation, unauthorized use or other infringement of our intellectual property rights. Further, we may 
not be able to effectively protect our intellectual property rights from misappropriation or other infringement in foreign 
countries where we have not applied for patent protections, and where effective patent, trademark, trade secret and other 
intellectual property laws may be unavailable, or may not protect our proprietary rights as fully as U.S. or Japan law. 
Particularly, our U.S. patents do not afford any intellectual property protection in China, Japan, Canada or other Asia 
locations, including Russia, where we have company operations.  

In the future, we may need to take legal actions to prevent third parties from infringing upon or misappropriating 

our intellectual property or from otherwise gaining access to our technology. Protecting and enforcing our intellectual 
property rights and determining their validity and scope could result in significant litigation costs and require significant 
time and attention from our technical and management personnel. If we fail to protect our intellectual property and other 
proprietary rights, or if such intellectual property and proprietary rights are infringed or misappropriated, our business, 
results of operations or financial condition could be materially harmed. 

We may be involved in intellectual property disputes, which could divert management’s attention, cause us to incur 
significant costs and prevent us from selling or using the challenged technology. 

Participants in the markets in which we sell our products have experienced frequent litigation regarding patent and 

other intellectual property rights. Numerous patents in these industries are held by others, including our competitors. In 
addition, from time to time, we have been notified that we may be infringing certain patents or other intellectual property 
rights of others. Regardless of their merit, responding to such claims can be time consuming, divert management’s 
attention and resources and may cause us to incur significant expenses. In addition, there can be no assurance that third 
parties will not assert infringement claims against us. While we believe that our products do not infringe in any material 
respect upon intellectual property rights of other parties and/or meritorious defense would exist with respect to any 
assertions to the contrary, we cannot be certain that our products would not be found infringing the intellectual property 
rights of others.  

In January 2010, Finisar Corporation, or Finisar, filed a complaint in the U.S. District Court for the Northern 
District of California against us and three other co-defendants. In the complaint, Finisar alleged infringement of certain 
of its U.S. patents arising from the co-defendants’ respective manufacture, importation, use, sale of or offer to sell certain 
optical transceiver products in the U.S. In March 2010, we filed an answer to the complaint and counterclaims, asserting 
two claims of patent infringement and additional claims asserting that Finisar has violated state and federal competition 
laws and violated its obligations to license on reasonable and non-discriminatory terms. In May 2010, the Court 
dismissed without prejudice all co-defendants (including us) except Source Photonics, Inc., on grounds that such claims 
should have been asserted in four separate lawsuits, one against each co-defendant. This dismissal without prejudice does 
not prevent Finisar from bringing a new similar lawsuit against us. In May 2012, we and Finisar agreed to toll our 
respective claims until the refiling of certain of the previously asserted claims from this dispute. As a result, Finisar is 
permitted to bring a new lawsuit against us if it chooses to do so, and we may bring new claims against Finisar upon 
seven days written notice prior to filing such claims. 

28 

 
Although we believe that we would have meritorious defenses to the infringement allegations and intend to defend 

any new similar lawsuit vigorously, there can be no assurance that we will be successful in our defense. Even if we are 
successful, we may incur substantial legal fees and other costs in defending the lawsuit. Further, a new lawsuit, if 
brought by either party, would be likely to divert the efforts and attention of our management and technical personnel, 
which could harm our business. 

If we fail to obtain the right to use the intellectual property rights of others which are necessary to operate our 
business, and to protect their intellectual property, our business and results of operations will be adversely affected. 

From time to time we may choose to or be required to license technology or intellectual property from third parties 

in connection with the development of our products. Failure to obtain a necessary third-party license required for our 
product offerings or to develop new products and product enhancements could adversely affect our business.  

Participation in standards setting organizations may subject us to intellectual property licensing requirements or 
limitations that could adversely affect our business and prospects. 

In the course of our participation in the development of emerging standards for some of our present and future 

products, we may agree to grant to all other participants a license to our patents that are essential to the practice of those 
standards on reasonable and non-discriminatory, or RAND, terms. If we fail to limit to whom we license our patents, or 
fail to limit the terms of any such licenses, we may be required to license our patents or other intellectual property to 
others in the future, which could limit the effectiveness of our patents against competitors.   

Any potential dispute involving our products, services or technology could also include our customers using our 
products, which could trigger our indemnification obligations to them and result in substantial expenses to us. 

In any potential dispute involving allegations that our products, services or technology infringe the intellectual 
property rights of third parties, our customers could also become the target of litigation. Because we often indemnify our 
customers for intellectual property claims made against them for products incorporating our technology, any claims 
against our customers could trigger indemnification obligations in some of our supply agreements, which could result in 
substantial expenses such as increased legal expenses, product recalls, damages for past infringement or royalties for 
future use.  

Natural disasters, terrorist attacks or other catastrophic events could harm our operations and our financial results. 

Our worldwide operations could be subject to natural disasters and other business disruptions, which could harm 

our future revenue and financial condition and increase our costs and expenses. For example, our corporate headquarters 
and wafer fabrication facility in Silicon Valley, California and our Tokyo, Japan facility are located near major 
earthquake fault lines, and our manufacturing facilities are located in Shenzhen and Dongguan, China, areas that are 
susceptible to typhoons. We are not insured against many natural disasters, including earthquakes. 

Similarly, our worldwide operations could be subject to secondary effects of natural disasters, terrorist attacks or 
other catastrophic events. Even if our facilities are not directly affected, any of these types of events could substantially 
disrupt the business of our suppliers or customers, which could have a material adverse effect on us.  

Rapidly changing standards and regulations could make our products obsolete, which would cause our revenue and 
results of operations to suffer. 

We design our products to conform to regulations established by governments and to standards set by industry 
standards bodies worldwide, such as The American National Standards Institute, the European Telecommunications 
Standards Institute, the International Telecommunications Union and the Institute of Electrical and Electronics 
Engineers. Various industry organizations are currently considering whether and to what extent to create standards for 
elements used in 100Gbps and beyond systems. Because certain of our products are designed to conform to current 
specific industry standards, if competing or new standards emerge that are preferred by our customers, we would have to 
make significant expenditures to develop new products and our revenue and results of operations would suffer. 

29 

 
Potential changes in our effective tax rate could negatively affect our future results. 

We are subject to income taxes in the U.S., China, Japan and other foreign jurisdictions, and our domestic and 

international tax liabilities are subject to the allocation of expenses in differing jurisdictions. Our tax rate is affected by 
changes in the mix of earnings and losses in countries with differing statutory tax rates, certain non-deductible expenses 
and the valuation of deferred tax assets and liabilities, including our ability to utilize our net operating losses. Increases 
in our effective tax rate could negatively affect our results of operations. 

Our future results of operations may be subject to volatility as a result of exposure to fluctuations in foreign exchange 
rates, primarily the Chinese Renminbi (RMB) and Japanese Yen (JPY) exchange rates. 

We are exposed to foreign exchange risks. Foreign currency fluctuations may adversely affect our revenue and our 

costs and expenses, and hence our results of operations. A substantial portion of our business is conducted through our 
subsidiaries based in China, whose functional currency is the RMB and Japan, whose functional currency is the JPY, and 
a smaller amount in Russian Rubles (RUB). The value of the RMB against the U.S. dollar and other currencies and the 
value of the JPY and RUB against the U.S. dollar and other currencies fluctuate and are affected by, among other things, 
changes in political and economic conditions. 

To the extent that transactions by our subsidiaries in China and Japan are denominated in currencies other than the 

RMB and JPY, we bear the risk that fluctuations in the exchange rates of the RMB and JPY in relation to other 
currencies could decrease our revenue or increase our costs and expenses, therefore having an adverse effect on our 
future results of operations. 

While we generate a significant portion of our revenue in U.S dollars, a significant portion of our cost of goods 

sold are in RMB and JPY. Therefore appreciation in RMB and JPY against the U.S. dollar would negatively impact our 
cost of goods sold upon translation to U.S. dollars.  

We have entered into hedging transactions to reduce the short-term impact of foreign currency fluctuations. 

However, the availability and effectiveness of these hedging transactions may be limited and we may not be able to 
successfully hedge our exposure. In addition, our currency exchange variations may be magnified by Chinese exchange 
control regulations that restrict our ability to convert RMB into foreign currency. 

We have identified a material weakness in our internal control over financial reporting which could, if not 
remediated, result in material misstatements in our financial statements.  

As part of our annual evaluation of internal controls for fiscal 2016, our management identified several 

deficiencies (including inadequate written shipping procedures) in our internal control over financial reporting related to 
certain revenue cut-off procedures. These deficiencies aggregated to a material weakness in our controls over revenue 
cut-off procedures, which affected the timing of our revenue recognition. A material weakness is defined as a deficiency, 
or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that 
a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. 
While no actual material misstatements were identified for the three years ended December 31, 2016, the material 
weakness had not been remediated as of December 31, 2016. 

Over the course of 2017, we intend to develop and implement a remediation plan designed to address this material 

weakness. However, if our remediation measures are insufficient to address this material weakness, if any of our 
personnel overrides our controls or if additional material weaknesses in our internal control are discovered or occur in 
the future, our consolidated financial statements may contain material misstatements and we could be required to restate 
our financial results. For more information see “Item 9A. Controls and Procedures”. 

30 

 
 If we fail to maintain effective internal control over financial reporting in the future, the accuracy and timing of our 
financial reporting may be adversely affected. 

Our management is responsible for establishing and maintaining adequate internal control over our financial 

reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended, or the Exchange Act. 

Preparing our consolidated financial statements involves a number of complex manual and automated processes, 

which are dependent upon individual data input or review and require significant management judgment. One or more of 
these elements may result in errors that may not be detected and could result in a material misstatement of our 
consolidated financial statements. If we fail to maintain the adequacy of our internal controls over financial reporting, 
our business and operating results may be harmed and we may fail to meet our financial reporting obligations. If material 
weaknesses in our internal control are discovered or occur, our consolidated financial statements may contain material 
misstatements and we could be required to restate our financial results.  

Our internal control over financial reporting may not prevent or detect misstatements because of its inherent 
limitations, including the possibility of human error, the circumvention or overriding of controls, or fraud. Even effective 
internal controls can provide only reasonable assurance with respect to the preparation and fair presentation of financial 
statements. Any failure of our internal controls could adversely affect the results of the periodic management evaluations 
and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal 
control over financial reporting. If we cannot provide reliable financial reports or prevent fraud, our business and results 
of operations could be harmed, investors could lose confidence in our reported financial information, and the trading 
price of our stock may decline. 

We may be subject to disruptions or failures in information technology systems and network infrastructures that 
could have a material adverse effect on our business and financial condition. 

We rely on the efficient and uninterrupted operation of complex information technology systems and network 

infrastructures to operate our business. A disruption, infiltration or failure of our information technology systems as a 
result of software or hardware malfunctions, system implementations or upgrades, computer viruses, cyber attacks, third-
party security breaches, employee error, theft or misuse, malfeasance, power disruptions, natural disasters or accidents 
could cause breaches of data security, loss of intellectual property and critical data and the release and misappropriation 
of sensitive competitive information and partner, customer and employee personal data. Any of these events could harm 
our competitive position, result in a loss of customer confidence, cause us to incur significant costs to remedy any 
damages and ultimately materially adversely affect our business and financial condition. 

Covenants in our borrowing arrangements may limit our flexibility in responding to business opportunities and 
competitive developments and increase our vulnerability to adverse economic or industry conditions. 

We have lending arrangements with several financial institutions, which generally require us to maintain certain 
financial covenants and limit our ability to take certain actions such as incurring some kinds of additional debt, paying 
dividends, or engaging in certain transactions like mergers and acquisitions, investments and asset sales without the 
lenders’ consent. These restrictions may limit our flexibility in responding to business opportunities, competitive 
developments and adverse economic or industry conditions. In addition, a breach of any of these covenants, or a failure 
to pay interest or indebtedness when due under any of our credit facilities, could result in a variety of adverse 
consequences, including the acceleration of our indebtedness. 

We may be unable to utilize our net operating loss carryforwards to reduce our income taxes, which could adversely 
affect our future financial results. 

As of December 31, 2016, we had net operating loss, or NOL, carryforwards for U.S. federal and state tax 
purposes of $207.3 million and $51.0 million, respectively. As these net operating losses have not been utilized and may 
not be utilized prior to their expiration in the future. The utilization of the NOL and tax credit carryforwards are subject 
to a substantial limitation imposed by Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, and 
similar state provisions. We recorded deferred tax assets, net of valuation allowance, for the NOL carryforwards 

31 

 
currently available after considering the existing Section 382 limitation. If we incur an additional limitation under 
Section 382, then the NOL carryforwards, as disclosed, could be reduced by the impact of any future limitation that 
would result in existing NOL carryforwards and tax credit carryforwards expiring unutilized and increases in future tax 
liabilities. 

We may utilize conflict minerals in our production or rely on suppliers who utilize conflict minerals in their 
production, and the use of such conflict minerals may negatively impact our results of operations. 

Since 2013, we have been subject to reporting obligations for the use of conflict minerals originating in the 

Democratic Republic of the Congo and adjoining countries and subsequently have timely filed our conflict minerals 
reports with the SEC. If we fail to comply with these requirements, our operating results could be harmed. 

In some instances, we rely on third-party sales representatives to assist in selling our products, and the failure of these 
representatives to perform as expected could reduce our future revenue. 

Although we primarily sell our products through direct sales to systems vendors, we also sell our products to some 
of our customers through third-party sales representatives. Many of our third-party sales representatives also market and 
sell competing products from our competitors. Our third-party sales representatives may terminate their relationships 
with us at any time, or with short notice. Our future performance will also depend, in part, on our ability to attract 
additional third-party sales representatives that will be able to market and support our products effectively, especially in 
markets in which we have not previously distributed our products. If our third-party sales representatives fail to perform 
as expected or to operate their businesses effectively, our revenue and results of operations could be harmed. 

We are subject to environmental, health and safety laws and regulations, which could subject us to liabilities, increase 
our costs, or restrict our business or operations in the future. 

Our manufacturing operations and our products are subject to a variety of federal, state, local and international 

environmental, health and safety laws and regulations in each of the jurisdictions in which we operate or sell our 
products. Our failure to comply with present and future environmental, health or safety requirements, or the 
identification of contamination, could cause us to incur substantial costs, including cleanup costs, monetary fines, civil or 
criminal penalties, or curtailment of operations, which could have a material adverse effect on our business, financial 
condition and results of operations. 

Additionally, increasing efforts to control emissions of greenhouse gases, or GHG, may also impact us. Additional 

climate change or GHG control requirements are under consideration at the federal level in the U.S. and in China. 
Additional restrictions, limits, taxes, or other controls on GHG emissions could increase our operating costs and, while it 
is not possible to estimate the specific impact any final GHG regulations will have on our operations, there can be no 
assurance that these measures will not have significant additional impact on us. 

Risks Related to Our Operations in China 

Our business operations conducted in China are critical to our success. A significant portion of our revenue in 

2016 was recognized from customers for whom we shipped products to a location in China. Additionally, a substantial 
portion of our net property, plant and equipment, approximately 36% as of December 31, 2016, was located in China. 
We expect to make further investments in China in the foreseeable future. Therefore, our business, financial condition, 
results of operations and prospects are to a significant degree subject to economic, political, legal, and social events and 
developments in China. 

Adverse changes in economic and political policies in China, or Chinese laws or regulations could have a material 
adverse effect on business conditions and the overall economic growth of China, which could adversely affect our 
business. 

The Chinese economy differs from the economies of most developed countries in many respects, including the 

level of government involvement, level of development, growth rate and control of foreign exchange and allocation of 

32 

 
resources. The Chinese economy has been transitioning from a planned economy to a more market-oriented economy. 
Despite reforms, the government continues to exercise significant control over China’s economic growth by way of the 
allocation of resources, control over foreign currency-denominated obligations and monetary policy and provision of 
preferential treatment to particular industries or companies. Moreover, the laws, regulations and legal requirements in 
China, including the laws that apply to foreign-invested enterprises are relatively new and are subject to frequent 
changes. The interpretation and enforcement of such laws is uncertain. Any adverse changes to these laws, regulations 
and legal requirements, including tax laws, or their interpretation or enforcement, or the creation of new laws or 
regulations relating to our business, could have a material adverse effect on our business.  

Furthermore, any slowdown or economic downturn, whether actual or perceived, in China could have a material 

adverse effect on our business, financial condition and results of operation. 

The termination, expiration or unavailability of our preferential income tax treatment in China may have a material 
adverse effect on our operating results. 

Effective January 1, 2008, the China Enterprise Income Tax Law, or the EIT law, imposes a single uniform 
income tax rate of 25% on all Chinese enterprises, including foreign-invested enterprises. Historically, one of our 
subsidiaries in China qualified for a preferential 15% tax rate that is available for new and high technology enterprises. 
In June 2016, the State Administration of Taxation issued a notice to adjust the requirements for high technology 
enterprise status. As a result, we did not meet the requirements for 2016 and became subject to the 25% regular income 
tax rate, which may impact our operating results for 2016 and future years. 

Our subsidiaries in China may be subject to restrictions on dividend payments, on making other payments to us or 
any other affiliated company, and on borrowing or allocating tax losses among our subsidiaries. 

Current Chinese regulations permit our subsidiaries in China to pay dividends only out of their accumulated 

profits, if any, determined in accordance with Chinese accounting standards and regulations, which are different than 
U.S. accounting standards and regulations. In addition, our subsidiaries in China are required to set aside at least 10% of 
their respective accumulated profits each year, if any, to fund their statutory common reserves until such reserves have 
reached at least 50% of their respective registered capital, as well as to allocate a discretional portion of their after-tax 
profits to their staff welfare and bonus fund. As of December 31, 2016, our Chinese subsidiaries’ common reserves had 
not reached this threshold and, accordingly, these entities are required to continue funding such reserves with 
accumulated net profits. Accordingly, we may not be able to move our capital easily, which could harm our business. 

Restrictions on currency exchange may limit our ability to receive and use our revenue and cash effectively. 

Because a portion of our revenue is denominated in RMB, any restrictions on currency exchange may limit our 

ability to use revenue generated in RMB to fund any business activities we may have outside China or to make dividend 
payments in U.S. dollars. Under relevant Chinese rules and regulations, the RMB is convertible under the “current 
account,” which includes dividends, trade and service-related foreign exchange transactions, but not under the “capital 
account,” which includes foreign direct investment and loans, without the prior approval of the State Administration of 
Foreign Exchange, or SAFE. We cannot be certain that Chinese regulatory authorities will not impose more stringent 
restrictions on the convertibility of the RMB, especially with respect to foreign exchange transactions. If such restrictions 
are imposed, our ability to adjust our capital structure or engage in foreign exchange transactions may be limited. 

Uncertainties with respect to China’s legal system could adversely affect the legal protection available to us. 

Our operations in China are governed by Chinese laws and regulations. Our subsidiaries in China are generally 
subject to laws and regulations applicable to foreign investments in China and, in particular, laws applicable to wholly 
foreign-owned enterprises. China’s legal system is a civil law system based on written statutes. Unlike common law 
systems, it is a legal system where decided legal cases have limited value as precedents. However, China has not 
developed a fully-integrated legal system, and recently-enacted laws and regulations may not sufficiently cover all 
aspects of economic activities in China. Uncertainties in the Chinese legal system may impede our ability to enforce the 
contracts we have entered into with our distributors, business partners, customers and suppliers. In addition, protections 

33 

 
of intellectual property rights and confidentiality in China may not be as effective as in the U.S. or other countries or 
regions with more developed legal systems. All of these uncertainties could limit the legal protections available to us and 
could materially and adversely affect our business and operations. 

If the Chinese government determines that we failed to obtain approvals of, or registrations with, the requisite 
Chinese regulatory authority with respect to our current and past import and export of technologies, or failed to 
obtain the necessary licenses to file patent applications outside China for inventions made in China, we could be 
subject to sanctions, which could adversely affect our business. 

China imposes controls on technology import and export. The term “technology import and export” is broadly 
defined to include, without limitation, the transfer or license of patents, software and know-how, and the provision of 
services in relation to technology. Depending on the nature of the relevant technology, the import and export of 
technology to or from China requires either approval by, or registration with, the relevant Chinese governmental 
authorities. Additionally, the Chinese government requires the patent application for any invention made at least in part 
in China to be filed first in China, then undergo a government secrecy review and obtain a license before such 
application is filed in other countries. 

If the Chinese government determines that we failed to obtain follow required procedures and obtain the 
appropriate license before filing a patent application outside China for an invention made at least in part in China, our 
China patents on such products may be invalidated, which could have a material and adverse effect on our business and 
operations.  

China regulation of loans and direct investment by offshore holding companies to China entities may delay or prevent 
us from using our cash proceeds to make loans or additional capital contributions to our China subsidiaries. 

From time to time, we may make loans or additional capital contributions to our China subsidiaries. We cannot 

assure you that we will be able to obtain these government registrations or approvals on a timely basis, if at all, with 
respect to our future loans or capital contributions to our China subsidiaries. If we fail to receive such registrations or 
approvals, our ability to capitalize our China subsidiaries may be negatively affected, which could materially and 
adversely affect our liquidity and ability to fund and expand our business. 

Dividends paid to us by our Chinese subsidiaries may be subject to Chinese withholding tax. 

The EIT Law and the implementation regulations provide that a 10% withholding tax may apply to dividends 
payable to investors that are “non-resident enterprises,” to the extent such dividends are derived from sources within 
China and in the absence of any tax treaty that may reduce such withholding tax rate.  

Our contractual arrangements with our subsidiaries in China may be subject to audit or challenge by the Chinese tax 
authorities, and a finding that our subsidiaries in China owe additional taxes could substantially reduce our net 
income and the value of our stockholders’ investment. 

Under the applicable laws and regulations in China, arrangements and transactions among related parties may be 

subject to audit or challenge by the Chinese tax authorities. We would be subject to adverse tax consequences if the 
Chinese tax authorities were to determine that the contracts with or between our subsidiaries were not executed on an 
arm’s length basis, and as a result the Chinese tax authorities could require that our Chinese subsidiaries adjust their 
taxable income upward for Chinese tax purposes. Such an adjustment could adversely affect us by increasing our tax 
expenses.

We may have difficulty maintaining adequate management, legal and financial controls in China, which we are 
required to do in order to comply with Section 404 of the Sarbanes-Oxley Act and securities laws, and which could 
cause a material adverse impact on our consolidated financial statements, the trading price of our common stock and 
our business. 

Chinese companies have historically not adopted a western style of management and financial reporting concepts 

and practices, which includes strong corporate governance, internal controls and computer, financial and other control 
systems. Most of our middle management staff in China are not educated in the western system, and we may have 
difficulty hiring new employees in China with experience and expertise relating to accounting principles generally 
accepted in the U.S. and U.S. public-company reporting requirements. These issues could make it more difficult for us to 
establish and maintain adequate internal control over our financial reporting, which could then result in errors that could 
cause a material misstatement of our consolidated financial statements.  

We may be exposed to liabilities under the FCPA and Chinese anti-corruption laws, and any determination that we 
violated these laws could have a material adverse effect on our business. 

We are subject to the Foreign Corrupt Practices Act of 1977, or FCPA, and other laws that prohibit improper 
payments or offers of payments to foreign governments and their officials and political parties by U.S. persons and 
issuers as defined by the statute, for the purpose of obtaining or retaining business. We have operations, agreements with 
third parties and we make significant sales in China. China also strictly prohibits bribery of government officials. Our 
activities in China create the risk of unauthorized payments or offers of payments by our employees, consultants, sales 
agents or distributors, even though they may not always be subject to our control. Although we have implemented 
policies and procedures to discourage these practices by our employees, our existing safeguards and any future 
improvements may prove to be less than effective, and our employees, consultants, sales agents or distributors may 
engage in conduct for which we might be held responsible. Violations of the FCPA or anti-corruption laws in other 
countries may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could 
negatively affect our business, operating results and financial condition. 

Risks Related to Ownership of Our Common Stock 

Our stock price may be volatile due to fluctuation of our financial results from quarter-to-quarter and other factors. 

Our quarterly revenue and results of operations have varied in the past and may continue to vary significantly from 

quarter to quarter. This variability may lead to volatility in our stock price as research analysts and investors respond to 
these quarterly fluctuations. These fluctuations are due to numerous factors, including: 

•  fluctuations in demand for our products; 

•  the timing, size and product mix of sales of our products; 

•  changes in our pricing and sales policies, particularly in the first quarter of the year, or changes in the pricing 

and sales policies of our competitors; 

•  our ability to design, manufacture and deliver products to our customers in a timely and cost-effective manner 

and that meet customer requirements; 

•  quality control or yield problems in our manufacturing operations; 

•  our ability to timely obtain adequate quantities of the components used in our products; 

•  length and variability of the sales cycles of our products; 

•  unanticipated increases in costs or expenses; and 

•  fluctuations in foreign currency exchange rates. 

35 

 
The foregoing factors are difficult to forecast, and these, as well as other factors, could materially adversely affect 
our quarterly and annual results of operations in the future. In addition, a significant amount of our operating expenses is 
relatively fixed in nature due to our internal manufacturing, research and development, sales and general administrative 
efforts. Any failure to adjust spending quickly enough to compensate for a revenue shortfall could magnify the adverse 
impact of such revenue shortfall on our results of operations. Moreover, our results of operations may not meet our 
announced financial outlook or the expectations of research analysts or investors, in which case the price of our common 
stock could decrease significantly. There can be no assurance that we will be able to successfully address these risks. 

The market price of our common stock could be subject to wide fluctuations in response to, among other things, 

the risk factors described in this section of this Annual Report on Form 10-K, and other factors beyond our control, such 
as fluctuations in the valuation of companies perceived by investors to be comparable to us.  

The stock markets have experienced price and volume fluctuations that have affected and continue to affect the 

market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate 
to the operating performance of those companies. These broad market and industry fluctuations, as well as general 
economic, political and market conditions, such as recessions, sovereign debt or liquidity issues, interest rate changes or 
international currency fluctuations, may negatively affect the market price of our common stock. 

In the past, many companies that have experienced volatility in the market price of their stock have been subject to 

securities class action litigation. We may become the target of this type of litigation in the future. Securities litigation 
against us could result in substantial costs and divert our management’s attention from other business concerns, which 
could seriously harm our business. 

Our failure to prepare and file timely our periodic reports with the SEC may make it more difficult for us to access 
the public markets to raise debt or equity capital.  

In January 2017 we did not file a Current Report on Form 8-K reporting the completion of the sale of the assets of 

our Low Speed Transceiver Products within the time frame required by the SEC. As a result of our failure to file this 
Current Report by the filing date required by the SEC, we are not eligible to file or use a Form S-3 registration statement 
to conduct public offerings until our filings with the SEC have been timely made for a full year. Our ineligibility to use 
Form S-3 during this time period may have a negative impact on our ability to quickly access the public capital markets 
because we would be required to file a long-form registration statement and wait for the SEC to declare such registration 
statement effective. This may limit our ability to access the public markets quickly to raise debt or equity capital. Our 
limited ability to access the public markets could prevent us from pursuing transactions or implementing business 
strategies that we believe would be beneficial to our business. 

The concentration of our capital stock ownership with our principal stockholders, executive officers and directors and 
their affiliates may limit other stockholders’ ability to influence corporate matters. 

As of December 31, 2016, our executive officers and directors, and entities that are affiliated with them or that 
have a right to designate a director, beneficially own an aggregate of approximately 39% of our outstanding common 
stock. This significant concentration of share ownership may adversely affect the trading price for our common stock 
because investors often perceive disadvantages in owning stock in companies with controlling stockholders. Also, as a 
result, these stockholders, acting together, may be able to control our management and affairs and matters requiring 
stockholder approval, including the election of directors and approval of significant corporate transactions.  

Our charter documents and Delaware law could prevent a takeover that stockholders consider favorable and could 
also reduce the market price of our stock. 

Our amended and restated certificate of incorporation and our amended and restated bylaws contain provisions that 

could delay or prevent a change in control of our company. These provisions could also make it more difficult for 
stockholders to elect directors and take other corporate actions. These provisions include: 

•  providing for a classified board of directors with staggered, three-year terms; 

36 

 
•  not providing for cumulative voting in the election of directors; 

•  authorizing our board of directors to issue, without stockholder approval, preferred stock rights senior to those 

of common stock; 

•  prohibiting stockholder action by written consent; 

•  limiting the persons who may call special meetings of stockholders; and 

•  requiring advance notification of stockholder nominations and proposals. 

In addition, we have been governed by the provisions of Section 203 of the Delaware General Corporate Law 

since the completion of our initial public offering. These provisions may prohibit large stockholders, in particular those 
owning 15% or more of our outstanding common stock, from engaging in certain business combinations without 
approval of substantially all of our stockholders for a certain period of time. 

These and other provisions in our amended and restated certificate of incorporation, our amended and restated 

bylaws and under Delaware law could discourage potential takeover attempts, reduce the price that investors might be 
willing to pay for shares of our common stock in the future and result in the market price being lower than it would be 
without these provisions.

ITEM 3. 

LEGAL PROCEEDINGS  

From time to time, we are involved in litigation that we believe is of the type common to companies engaged in 

our line of business, including commercial disputes and employment issues. As of the date of this Annual Report on 
Form 10-K, other than as described below, we are not involved in any pending legal proceedings that we believe could 
have a material adverse effect on our financial condition, results of operations or cash flows. However, as described 
below, a certain dispute involves a claim by a third party that our activities infringe their intellectual property rights. This 

37 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
  
 
  
  
  
  
  
 
 
 
 
 
 
and other types of intellectual property rights claims generally involve the demand by a third party that we cease the 
manufacture, use or sale of the allegedly infringing products, processes or technologies and/or pay substantial damages 
or royalties for past, present and future use of the allegedly infringing intellectual property. Claims that our products or 
processes infringe or misappropriate any third-party intellectual property rights (including claims arising through our 
contractual indemnification of our customers) often involve highly complex, technical issues, the outcome of which is 
inherently uncertain. Moreover, from time to time, we may pursue litigation to assert our intellectual property rights. 
Regardless of the merit or resolution of any such litigation, complex intellectual property litigation is generally costly 
and diverts the efforts and attention of our management and technical personnel which could adversely affect our 
business.  

For a discussion of our current legal proceedings, please refer to the information set forth under the “Litigation” 
section in Note 12, Commitments and contingencies, in Notes to Consolidated Financial Statements in Item 8 of Part II 
of this Annual Report on Form 10-K, which is incorporated herein by reference.

ITEM 5.  MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND 

ISSUER PURCHASES OF EQUITY SECURITIES  

As of February 28, 2017, there were approximately 79 holders of record of our common stock (not including 
beneficial holders of our common stock holder in street names). We have not paid cash dividends on our common stock 
since our inception, and we do not anticipate paying any in the foreseeable future. Any future determination as to the 
declaration and payment of dividends, if any, will be at the discretion of our board of directors and will depend on then 
existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, 
business prospects, consent from our existing credit facility lender in the U.S., and other factors our board of directors 
may deem relevant.  

The following table sets forth, for the periods indicated, the high and low closing prices of our common stock as

Use of Proceeds 

In 2015, we completed our follow-on offering of 6,866,689 shares of our common stock in a registered public 
offering at $7.25 per share. We raised approximately $45.6 million, net of underwriting costs and other offering expenses 
of approximately $4.1 million. We held the proceeds received from our follow-on public offering as cash, cash 
equivalent and short-term investments and intend to continue to invest the funds in money market accounts and short-
term marketable securities including money market funds, government agency securities, corporate debt securities and 
U.S. government securities. There has been no material change in the planned use of proceeds from our follow-on public 
offering as described in our final prospectus filed with the SEC on May 22, 2015 pursuant to Rule 424(b).  

In both 2016 and 2015, we filed a resale registration statement, which registered 4,972,905 shares of the 

Company’s common stock, at a par value of $0.0025 per share, held by Rusnano. We do not receive any proceeds from

ITEM 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS 

OF OPERATIONS  

You should read the following discussion and analysis by our management of our financial condition and results of 

operations in conjunction with our consolidated financial statements and the accompanying notes.  

The following discussion contains forward-looking statements that involve risks and uncertainties, such as 
statements of our plans, objectives, expectations and intentions. Our actual results could differ materially from those 
discussed in the forward-looking statements. Please also see the cautionary language at the beginning of Part I of this 
Annual Report on Form 10-K regarding forward-looking statements. Factors that could cause or contribute to such 
differences include, but are not limited to, those discussed in “Risk Factors” of this Annual Report on Form 10-K.  

Business overview  

We develop, manufacture and sell optoelectronic products that transmit, receive and switch high speed digital 

optical signals for communications networks. We sell our products to the world’s leading network equipment 
manufacturers, including Nokia (formerly Alcatel-Lucent, which was acquired by Nokia in January 2016), Ciena 
Corporation, Cisco Systems, Inc., HiSilicon Technologies, Ltd., an affiliate of Huawei Technologies, Co., Ltd. and 
Huawei Technologies Co., Ltd. (collectively “Huawei”). These companies are among our largest customers and a focus 
of our strategy due to their leading market positions.  

We have research and development and wafer fabrication facilities in San Jose and Fremont, California and in 

Tokyo, Japan that coordinate with our research and development and manufacturing facilities in Dongguan, Shenzhen 
and Wuhan, China and Ottawa, Canada. We use proprietary design tools and design-for-manufacturing techniques to 
align our design process with our precision nanoscale, vertically integrated manufacturing and testing. We believe we are 
one of the highest volume PIC manufacturers in the world and that we can further expand our manufacturing capacity to 
meet market needs. 

Recognizing our focus on growth in our 100Gbps (“100G”) and beyond products, we align our product group 

reporting to “High Speed Products” which includes products designed for 100G and beyond applications and “Network 
Products and Solutions,” which comprises all products designed for applications below 100G.  In 2016 and 2015, High 
Speed Products represented approximately 67% and 58% of total revenue, respectively, and Network Products and 
Solutions represented approximately 33% and 42% of total revenue, respectively.  

In 2016, our revenue growth of 21% compared to 2015 was driven primarily by demand for our High Speed 

Products, as carriers continued to accelerate deployment of high capacity optical transport networks worldwide, 
particularly in China. Our gross margin was 28.5% in the year ended December 31, 2016 compared to 29.2% in the year 
ended December 31, 2015. The decrease in gross margin year over year was primarily attributable to higher stock-based 
compensation expense, unfavorable cost of goods sold impact as a result of the recoverable inventory associated with the 
bankruptcy reorganization by one of our distributors and lower pricing, partially offset by cost reduction and favorable 
product mix. In December 2016, we entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with 
APAT Optoelectronics Components Co., Ltd. (the “Purchaser”) for the sale of certain assets of our access and low speed 
transceiver product lines (the “Low Speed Transceiver Products”) which was completed in January 2017. All of these 
products were part of our Network Products and Solutions group and include the low speed passive optical network, or 
PON, products for which the end-of-life plan was announced in mid-2016. In 2016, 2015 and 2014, the Low Speed 
Transceiver Products generated approximately 15%, 27% and 36% of our total revenue, respectively.  

The asset sale consists of approximately $25.0 million in cash consideration plus approximately $1.4 million post-
closing transition services under a transition services agreement with the Purchaser. The purchase price was reduced by 
$3.4 million after closing for inventory adjustments and is subject to other adjustments of up to $10.0 million for any 
potential indemnification claims. 

In 2017, we expect continued volume growth for our High Speed Products, although quarter-to-quarter results may 

show considerable variability as is usual in a rapid initial ramp-up following the introduction of new technologies.

Similar to revenue, our gross margins may fluctuate materially depending on a variety of factors including average 
selling price changes, product mix, volume, manufacturing utilization and ongoing manufacturing process 
improvements. 

Critical accounting policies and estimates  

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated 

financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. 
(“U.S. GAAP”). These principles require us to make estimates and judgments that affect the reported amounts of assets, 
liabilities, revenue, expenses and cash flow, and related disclosure of contingent assets and liabilities. Our estimates 
include those related to revenue recognition, stock-based compensation expense, impairment analysis of goodwill and 
long-lived assets, valuation of inventory, purchased intangibles, warranty liabilities and accounting for income taxes. We 
base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the 
circumstances. Actual results may differ from these estimates. To the extent that there are material differences between 
these estimates and our actual results, our future financial statements will be affected.  

We believe that of our significant accounting policies, which are described in Note 2 of Notes to Consolidated 

Financial Statements, the following accounting policies involve a greater degree of judgment and complexity. 
Accordingly, we believe these are the most critical to fully understand and evaluate our financial condition and results of 
operations.  

Revenue recognition  

We recognize revenue from the sale of our products provided that persuasive evidence of an arrangement exists, 
delivery has occurred, the price is fixed or determinable and collectability is reasonably assured. We recognize revenue 
when the product is shipped and title has transferred to the buyer. We bear all costs and risks of loss or damage to the 
goods up to that point. On most orders, our terms of sale provide that title passes to the buyer upon shipment by us. In 
certain cases, our terms of sale may provide that title passes to the buyer upon delivery of the goods to the buyer. 
Revenue related to the sale of consignment inventory at customer vendor managed locations is not recognized until the 
product is pulled from inventory stock by customers. Payments made to third-party sales representatives are recorded to 
sales and marketing expense and not a reduction of revenue as the sales agent services they provide have an identifiable 
benefit and are made at similar rates of other sales agent service providers.  

The amount of revenue recognized in a given period is affected by our judgement. Contracts and/or customer 

purchase orders are assessed to determine the existence of an arrangement. Shipping documents and customer 
acceptance, when applicable, are used to verify delivery. We assess whether the fee is fixed or determinable based on the 
payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. We assess 
collectability based primarily on the creditworthiness of the customer as determined by credit checks and the customer’s 
payment history. Our estimates are based on historical experience. If the actual amounts are significantly different from 
our estimates, our operating results could have a material impact. 

Stock-based compensation expense  

We grant stock options, stock appreciation units and restricted stock units to employees, directors and consultants. 

Stock purchase rights are granted to our employees. Stock-based awards are accounted for at fair value as of the 
measurement date using the Black-Scholes-Merton option-pricing model, the lattice-binominal option-pricing model or 
stock prices. For stock options and restricted stock units, the measurement date is the grant date and for employee stock 
purchase rights the measurement date is the first day of the offering period. Stock appreciation units are subject to re-
measurement each reporting period.  

We recognize the fair value over the period during which an employee is required to provide services in exchange 

for the award, known as the requisite service period (usually the vesting period) on a straight-line basis. Stock-based 
compensation expense includes the impact of estimated forfeitures. We estimate future forfeitures at the date of grant and 
revise the estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.  

44 

 
 
 
 
 
 
 
 
 
 
Determining the appropriate fair value model and calculating the fair value of stock-based awards requires 
judgment, including estimating stock price volatility, forfeiture rates and expected life. If any of these assumptions, or 
the market price of our common shares, used in the option-pricing models change, our stock-based compensation 
expense could materially change our consolidated financial statements.  

Business Combinations  

We allocate the fair value of purchase consideration to the tangible and intangible assets acquired and liabilities 

assumed based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values 
of these identifiable assets and liabilities is recorded as goodwill. When determining the fair values of assets acquired 
and liabilities assumed, management makes significant estimates and assumptions, especially with respect to intangible 
assets. Critical estimates in valuing certain intangible assets include but are not limited to future expected cash flows 
from customer relationships and acquired patents and developed technology; and discount rates. 

Fair value estimates are based on the assumptions management believes a market participant would use in pricing 
the asset or liability. Such assumptions are believed to be reasonable but are inherently uncertain and unpredictable and, 
as a result, actual results may differ from estimates.  

Amounts recorded in a business combination may change during the measurement period, which is a period not to 

exceed one year from the date of acquisition, as additional information about conditions existing at the acquisition date 
becomes available.  

Goodwill and long-lived assets  

Our methodology for allocating the purchase price relating to purchase acquisitions is determined through 
established valuation techniques. Goodwill represents a residual value as of the acquisition date, which generally results 
in measuring goodwill as an excess of the purchase consideration transferred plus the fair value of any noncontrolling 
interest in the acquired company over the fair value of net assets acquired, including any contingent consideration.  

We perform annual goodwill impairment test in the fourth fiscal quarter by reporting unit. We could be subject to 

additional goodwill impairment tests in the event of changes in industry and market conditions, our business and 
reporting structure. During the fourth quarter of fiscal 2016, we performed a sensitivity analysis for goodwill impairment 
and determined that the estimated fair value substantially exceeded the carrying value of the underlying goodwill and a 
hypothetical 10% decline in the fair value of the reporting unit would not result in an impairment of goodwill. 

We assess the impairment of long-lived assets whenever events or changes in circumstances indicate that the 
carrying amount may not be recoverable. An impairment loss would be recognized when the sum of the future net cash 
flows expected to result from the use of the asset and its eventual disposition is less than its carrying amount. The 
estimated future cash flows are based upon, among other things, assumptions about expected future operating 
performance and may differ from actual cash flows. If our estimates regarding future cash flows derived from such assets 
were to change, we may record an impairment to the value of these assets.  

Valuation of inventories  

We record inventories at the lower of cost (using the first-in, first-out method) or market, after we give appropriate 

consideration to obsolescence and inventories in excess of anticipated future demand. In assessing the ultimate 
recoverability of inventories, we are required to make estimates regarding future customer demand, the timing of new 
product introductions, economic trends and market conditions. If the actual product demand is significantly lower than 
forecasted, we could be required to record additional inventory write-downs which would be charged to cost of goods 
sold. Obsolescence is determined from several factors, including competitiveness of product offerings, market conditions 
and product life cycles. Write-downs of excess and obsolete inventory are charged to cost of goods sold. At the point of 
the loss recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts and 
circumstances do not result in the restoration or increase in that newly established cost basis. If this lower-cost inventory 

45 

 
 
 
 
 
 
 
 
 
 
 
 
is subsequently sold, it will result in lower costs and higher gross margin for those products. Any write-downs would 
have an adverse impact on our gross margin. In 2016, 2015 and 2014, inventory write-down charges were approximately 
$3.0 million, $6.5 million and $1.5 million, respectively. Our inventory write-down charges in 2015 included a $2.8 
million charge resulting from the phasing-out of our earlier-generation tunable laser products.  

Warranty liabilities  

We provide warranties to cover defects in workmanship, materials and manufacturing of our products to meet 
stated functionality specifications. We test products against specified functionality requirements prior to delivery, but we 
nevertheless from time to time experience claims under our warranty guarantees. We accrue for estimated warranty costs 
under those guarantees based upon historical experience, and for specific items at the time their existence is known and 
the amounts are determinable. We charge a provision for estimated future costs related to warranty activities to cost of 
goods sold based upon historical product failure rates and historical costs incurred in correcting product failures. We 
recorded warranty expense of $0.1 million, $0.1 million and $0.9 million for each of the years ended December 31, 
2016, 2015 and 2014, respectively. If we experience an increase in warranty claims compared with our historical 
experience, or if the cost of servicing warranty claims is greater than expected, our gross margin and profitability would 
be adversely affected. 

Accounting for income taxes  

We record income taxes using the asset and liability method, which requires the recognition of deferred tax assets 
and liabilities for the expected future tax consequences of events that have been recognized in our consolidated financial 
statements or tax returns. In estimating future tax consequences, generally we consider all expected future events, other 
than enactments or changes in tax law or rates. We provide valuation allowances when necessary to reduce deferred tax 
assets to the amount expected to be realized.  

We operate in various tax jurisdictions and are subject to audit by various tax authorities. We provide for tax 
contingencies whenever it is deemed probable that a tax asset has been impaired or a tax liability has been incurred for 
events such as tax claims or changes in tax laws. Tax contingencies are based upon their technical merits, relevant tax 
law and the specific facts and circumstances as of each reporting period. Changes in facts and circumstances could result 
in material changes to the amounts recorded for such tax contingencies.  

As part of the process of preparing our consolidated financial statements, we are required to estimate our taxes in 

each of the jurisdictions in which we operate. We estimate actual current tax exposure together with assessing temporary 
differences resulting from differing treatment of items, such as accruals and allowances not currently deductible for tax 
purposes. These differences result in deferred tax assets.  

We make estimates and judgments about our future taxable income that are based on assumptions that are 

consistent with our plans and estimates. Should the actual amounts differ from our estimates, the amount of our valuation 
allowance could be materially impacted. Any adjustment to the deferred tax asset valuation allowance would be recorded 
in the consolidated statement of operations in the period that the adjustment is determined to be required.

Results of operations  

Our business is focused on the highest speed digital optics and signal processing communications applications. In 
2016, we entered into an Asset Purchase Agreement for the sale of assets of our Low Speed Transceiver Products within 
our Network Products and Solutions product group. In 2016, 2015 and 2014, the Low Speed Transceiver Products 
represent approximately 15%, 27% and 36% of total revenue, respectively. The asset sale was closed on January 2017. 

In 2016, our stock-based stock options and stock appreciation units with market conditions vested when the 
average closing price of our common stock over 20 consecutive trading days exceeded $15.00 per share and we recorded 
approximately $5.7 million in related stock-based compensation expense within cost of goods sold and operating 
expenses.  

We acquired the tunable laser product lines of EMCORE Corporation in January 2015 and the optical power 
monitoring business of EigenLight Corporation in November 2015 and the results of operations from these acquisitions 
are included from the date of acquisition.

We sell substantially all of our products to original equipment manufacturers, or OEMs. We price our products 

based on market and competitive conditions and may periodically reduce the price of our products as market and 
competitive conditions change and as manufacturing costs are reduced. Our sales transactions to customers are 
denominated primarily in U.S. dollars, Chinese Renminbi (“RMB”) and Japanese Yen (“JPY”). Revenue is driven by the 
volume of shipments and may be impacted by pricing pressures. We have generated most of our revenue from a limited 
number of customers.

(1) Huawei’s percentage of revenue included its affiliate, HiSilicon. Revenue from HiSilicon represented 
approximately 36%, 23% and 15% of total revenue, respectively, in 2016, 2015 and 2014.  

For the years ended December 31, 2016, 2015 and 2014, our percentage of sales from our China-based 

subsidiaries, the majority of which were denominated in RMB, were 4%, 5% and 20%, respectively.  

Total revenue increased by $72.0 million, or 21%, in 2016 compared to 2015.  The increase was primarily 
attributable to an increase in revenue from our High Speed Products driven by product demand, partially in China. Our 
High Speed Products increased to 67% of revenue in 2016 from 58% in 2015 and our Network Products and Solutions 
revenue decreased from 42% in 2015 to 33% in 2016. The increase in High Speed Products revenue was partially offset 
by a decrease in Network Products and Solutions revenue largely due to our product phase-out efforts to improve our 
gross margin. In 2016, total revenue from China, the United States, Japan and rest of the world was $254.7 million, 
$67.8 million, $12.0 million and $76.9 million, respectively, compared to $182.5 million, $77.9 million, $12.7 million 
and $66.4 million, respectively, in 2015.  

Total revenue increased by $33.3 million, or 11%, in 2015 compared to 2014. The increase was primarily 
attributable to an increase in revenue from our High Speed Products driven by customer demand and acquisition of the 
tunable laser products from EMCORE. Our High Speed Products increased from 42% in 2014 to 58% of total revenue in 
2015 and our Network Products and Solutions revenue decreased from 58% in 2014 to 42% in 2015. The increase in 
High Speed Products revenue was partially offset by a decrease in Network Products and Solutions revenue largely due 
to our product phase-out efforts to improve our gross margin. In 2015, revenue from the United States increased $21.3 
million, or 38%, and revenue from China increased $21.0 million, or 13%, partially offset by decreases in Japan and 
other regions, compared to 2014. In 2015, total revenue from China, the United States, Japan and rest of the world was 
$182.5 million, $77.9 million, $12.7 million and $66.4 million, respectively. Revenue related to products acquired from 
EMCORE was approximately $55.8 million in 2015. 

In 2017, we expect continued growth in revenue from our High Speed Products. We also expect that a significant 
portion of our revenue will continue to be derived from a limited number of customers. We expect a significant portion 
of our sales to continue to be denominated in foreign currencies, including RMB, and, to a lesser extent, in JPY, and 
therefore may be affected by changes in foreign currency exchange rates.

Our cost of goods sold consists primarily of the cost to produce wafers and to manufacture and test our products. 
Additionally, our cost of goods sold includes stock-based compensation, write-downs of excess and obsolete inventory, 
royalty payments, amortization of certain purchased intangible assets, depreciation, acquisition-related fair value 
adjustments, restructuring cost, warranty, shipping and allocated facilities costs.  

In 2016, gross profit increased $18.1 million, or 18%, to $117.1 million in 2016, compared to $99.1 million in 
2015, primarily attributable to revenue growth, volume increase and cost reduction, partially offset by lower pricing, 
higher stock-based compensation expense and an unfavorable cost of goods sold impact as a result of the unrecoverable 
inventory associated with the bankruptcy reorganization by one of our distributors.  

Gross margin decreased by approximately one percentage point to 28.5% in 2016 from 29.2% in 2015, primarily 

attributable to a $1.8 million increase in stock-based compensation expense and a $1.4 million unfavorable cost of goods 
sold impact as a result of the unrecoverable inventory associated with the bankruptcy reorganization by one of our 
distributors and lower pricing, partially offset by production cost reduction and favorable product mix resulting from an 
increase in sales volume of our High Speed Products. 

In 2015, gross profit increased $28.0 million, or 39%, to $99.1 million in 2015, compared to 2014, attributable to 

revenue growth partially offset by a $3.2 million increase in manufacturing costs, a $2.8 million inventory-related charge 
due to the phase out of our earlier-generation tunable laser products, and a $0.5 million increase in intangible assets 
related amortization expenses due to our acquisition of the tunable laser products from EMCORE. Gross margin 
increased six percentage points to 29% in 2015 from 23% in 2014, primarily attributable to favorable product mix 
resulting from an increase in sales volume of our High Speed Products, our product cost reduction activities and product 
phase out efforts of low margin products, partially offset by price adjustments. 

We expect that our gross margin is likely to increase in 2017 due to a variety of factors, including favorable 
product mix, vertical integration, reduced amortization expense for purchased intangible assets and introduction of new 
products. Other factors that can affect our gross margin include production volume, inventory changes, changes in the 
average selling prices of our products, changes in the cost and volumes of materials purchased from our suppliers, 
changes in labor costs, changes in overhead costs or requirements, revaluation of stock appreciation unit awards that are 
impacted by our stock price, write-downs of excess and obsolete inventories and warranty costs. In addition, we 
periodically negotiate pricing with certain customers which can cause our gross margins to fluctuate, particularly in the 
quarters subsequent to the periods in which the negotiations occurred.

We focus our research and development effort primarily on the high speed market. Research and development 

expense increased $12.8 million, or 29%, in 2016 compared to 2015.  The increase was primarily attributable to a $5.1 
million increase in development expenses largely driven by prototype and material spending, a $3.0 million increase in

salaries and benefits, a $2.7 million increase in stock-based compensation and a $1.7 million increase in consulting fees 
for new product development.  

Research and development expense decreased $1.4 million, or 3%, in 2015 compared to 2014.  The decrease was 

primarily attributable to a $3.3 million decrease in development expenses driven by lower prototype and material 
spending, a $0.5 million decrease in depreciation expense and a $0.4 million decrease in administrative and travel 
expenses, partially offset by a $1.8 million increase in consulting fees for new product development and a $1.0 million 
increase in variable compensation expenses.  

We believe that investments in research and development are important to help meet our strategic objectives. In 
2017, we plan to continue to invest in research and development activities, including new products that we believe will 
further enhance our competitive position. Research and development expense consists of personnel costs, including 
stock-based compensation, for our research and development personnel, and product development costs, including 
engineering services, development software and hardware tools, depreciation of equipment and facility costs. We record 
all research and development expense as incurred. As a percentage of total revenue, our research and development 
expense may vary as our investment and revenue levels change over time.  

Sales and marketing  

Sales and marketing expense increased by $2.8 million, or 18%, in 2016 compared to 2015, primarily due to a $2.3 
million increase in stock-based compensation expense, a $1.0 million increase in salaries and benefits and a $0.6 million 
increase in commission expense, partially offset by a $1.0 million decrease in bad debt provision largely due to 
collections. 

Sales and marketing expense increased by $2.1 million, or 15%, in 2015 compared to 2014, primarily due to a $0.9 

million increase in bad debt provision largely due to a customer filing for bankruptcy and specific doubtful accounts, a 
$0.8 million increase in variable compensation expenses, a $0.5 million increase in payroll and benefits, a $0.4 million 
increase in stock-based compensation expense largely driven by the increase in the price of our common stock, a $0.3 
million increase in product demo spending and a $0.3 million increase in travel costs, partially offset by a $0.7 million 
decrease in net allocated overhead charges and a $0.5 million decrease in commission expense. 

We expect to continue to expand our high speed market focus and increase sales coverage of DCI market while 
controlling our sales and marketing expenses in 2017, even as our business continues to expand geographically. Sales 
and marketing expense consists primarily of personnel costs, including stock-based compensation and sales 
commissions, costs related to sales and marketing programs and services and facility costs. As a percentage of total 
revenue, our sales and marketing expense may vary as our revenue changes over time. 

General and administrative  

General and administrative expense consists of personnel costs, including stock-based compensation, for our 

finance, human resources and information technology personnel and certain executive officers, as well as professional 
services costs related to accounting, tax, banking, legal and information technology services, depreciation and facility 
costs.  

General and administrative expense increased by $2.8 million, or 9%, in 2016 compared to 2015. The increase was 
primarily due to a $2.5 million increase in stock-based compensation, a $0.7 million increase in salaries and benefits, and 
a $0.4 million increase in outside services driven by legal fees, partially offset by a $0.8 million decrease in variable 
compensation expenses. 

General and administrative expense increased by $0.1 million in 2015 compared to 2014. The increase was 
primarily due to a $2.6 million increase in payroll and benefits, a $1.7 million increase in variable compensation 
expenses, a $0.6 million increase in stock-based compensation primarily driven by higher stock price of our common 
stock, partially offset by a $2.0 million decrease in audit fees, a $1.3 million decrease in consulting fees, a $0.8 million 
decrease in depreciation expense, and a $0.7 million decrease in facility charges largely driven by lower utility expenses.

We expect to continue to focus on controlling our general and administrative expense in 2017. As a percentage of 

total revenue, our general and administrative expense may vary as our revenue changes over time. 

Amortization of purchased intangible assets  

Our intangible assets are being amortized over their estimated useful lives. Amortization expense relating to 
technology and patents and leasehold interests are included within cost of goods sold, while customer relationships and 
non-compete agreements are recorded within operating expenses.  

In 2016, amortization of purchased intangible assets was $4.5 million, comprising of $2.9 million in cost of goods 

sold and $1.6 million in operating expenses. Amortization of purchased intangible assets decreased by approximately 
$0.7 million in 2016 compared to 2015, primarily due to certain intangible assets from our past acquisitions being fully 
amortized. 

In 2015, amortization of purchased intangible assets was $5.1 million, comprising of $3.3 million in cost of goods 

sold and $1.8 million in operating expenses. Amortization of purchased intangible assets increased by $0.8 million in 
2015 compared to 2014, primarily due to intangible assets from our acquisition of the tunable laser product business 
from EMCORE in 2015. 

Acquisition and asset sale related costs 

In 2016, we incurred $2.1 million in acquisition and asset sale related transaction costs related to legal, accounting 

and other professional services for our acquisition and asset sale activities. 

In 2015, we incurred $0.9 million in acquisition-related transaction costs related to legal, accounting and other 

professional services for our acquisition activities, including our acquisitions of EMCORE’s tunable laser product lines 
and EigenLight’s optical power monitoring business. 

In 2014, we incurred $0.6 million in acquisition-related transaction costs related to our acquisition of EMCORE’s 

tunable laser product lines. 

Asset impairment charge 

There were no asset impairment charges in 2016. In 2015, we recognized asset impairment charges of $0.4 million 

of which $0.2 million was attributable to a write-down of held-for-sale assets acquired from EMCORE and $0.2 million 
was attributable to charges for equipment related to our product phase out effort. In 2014, we wrote off certain leasehold 
improvements in our facilities in Fremont, California and recorded an asset impairment charge of $1.1 million in 2014 as 
a result of our business re-alignment initiatives. 

Restructuring charges  

There were no restructuring charges in 2016. We recorded $0.2 million and $1.1 million in related restructuring 

charges in 2015 and 2014, respectively, within cost of goods sold and operating expenses. 

Escrow settlement gain and adjustment to the fair value of contingent consideration  

In 2014, we recognized a $4.9 million escrow settlement gain including $3.9 million pertained to the Santur 

acquisition and $1.0 million pertained to the NeoPhotonics Semiconductor acquisition.

Interest and other income, net consists of interest income, interest expense and other income, net. Interest income 

consists of income earned on our cash, cash equivalents and short-term investments. Interest expense consists of amounts 
incurred for interest on our outstanding debt. Other income, net includes foreign currency transaction gains and losses 
along with government subsidies. The functional currency of our subsidiaries in China and Japan is the RMB and the 
JPY, respectively.  

Interest and other income, net decreased $2.4 million, or 87%, in 2016 from $0.9 million in 2015. The decrease 

was primarily due to a $3.5 million decrease in other income, net driven by foreign exchange loss resulting from a 
weaker RMB and a stronger JPY against the U.S. dollars, partially offset by a $0.8 million decrease in interest expense 
and a $0.2 million increase in interest income. 

Interest and other income, net increased $0.9 million, or 46%, in 2015 from $1.9 million in 2014.  The increase 

was primarily due to a $0.1 million decrease in the Rusnano payment derivative liability related to the Rights Agreement 
with Rusnano in 2015, compared to a $0.3 million increase in 2014, and a $0.4 million increase in foreign exchange gain 
primarily attributable to stronger U.S. dollars in 2015.

 (15)%   

In 2016, our income tax provision was primarily related to the operating profit realized in our foreign subsidiaries 

in Japan and China. Historically, we have experienced net losses in the U.S. and in the short term, we expect this trend to 
continue. In China, one of our subsidiaries changed from a preferential 15% tax rate available for high technology 
enterprises to 25% for 2016. The preferential rate applied to 2015 and 2014. We realized benefits from this 10% 
reduction in the tax rate of $0.9 million and $0.5 million for 2015 and 2014, respectively.  

The effective tax rate in 2016 of 106% was 60 percentage points higher than the 2015 effective tax rate mainly due 

to the non-recurring vesting of the stock-based awards with a market condition in 2016 and, to a lesser extent, an 
increase in our tax rate in China. 

The effective tax rate in 2015 of 46% was 31 percentage points higher than the 2014 effective tax rate due to 

higher earnings in foreign jurisdictions and reduced net loss generated in the U.S. 

Liquidity and capital resources  

At December 31, 2016, we had working capital of $124.5 million and total cash, cash equivalents and short-term 
investments and restricted cash of $105.6 million, of which 21% was held in accounts by our subsidiaries in China and 
8% was held in accounts by our subsidiaries in Japan. In the aggregate, approximately 29% of our cash, cash equivalents 
and short-term investments were held by our foreign subsidiaries. If we repatriate any of our funds held by our foreign 
subsidiaries, we could be subject to foreign withholding taxes. 

Approximately $8.7 million of retained earnings with our accumulated deficit at December 31, 2016 was subject to 

restriction due to the fact that our subsidiaries in China are required to set aside at least 10% of their respective 
accumulated profits each year to fund statutory common reserves as well as allocate a discretional portion of their after-

tax profits to their staff welfare and bonus fund.  This restricted amount is not distributable as cash dividends except in 
the event of liquidation. 

In 2015, we completed our follow-on offering of 5,971,034 shares of our common stock in a registered public 
offering at $7.25 per share and the underwriters in our follow-on offering exercised an option to purchase 895,655 shares 
of our common stock at a price of $7.25 per share. We raised approximately $45.6 million, net of underwriting costs and 
other directly related costs of approximately $4.1 million. 

In 2017, we completed the sale of certain Low Speed Transceiver Products’ assets for an approximately $25.0 

purchase price plus an approximately $1.4 million post-closing transition services fees. The purchase price was reduced 
by $3.4 million for inventory adjustment and is subject to other adjustments of up to $10.0 million for any potential 
claims. See Note 18 in Notes to Consolidated Financial Statements in Item 8 of Part II of this Report. 

We have a bank credit agreement, as amended, with Comerica Bank in the U.S. (the “Comerica Bank Credit 

Facility”). Amounts borrowed under the Comerica Bank Credit Facility are due on or before April 30, 2017 and 
borrowings bear interest at an interest rate option of a base rate as defined in the agreement plus 1.75% or LIBOR plus 
2.75%. See Note 10 of Notes to Consolidated Financial Statements in Item 8 of Part II of this Report. As of December 
31, 2016, the rate on the LIBOR option was 3.37% and the outstanding balance was $23.8 million, which was repaid in 
full in January 2017.  

We regularly issue short-term notes payable to our suppliers in China in exchange for accounts payable. As a 
condition of the notes payable arrangements, we are required to keep a compensating balance at the issuing banks that is 
a percentage of the total notes payable balance until the amounts are settled. As of December 31, 2016, our subsidiary in 
China had three short-term line of credit facilities with banking institutions. As of December 31, 2016 and 2015, the non-
interest bearing bank acceptance drafts issued in connection with our notes payable to our suppliers in China under these 
line of credit facilities had an outstanding balance of $6.4 million and $8.9 million, respectively. Compensating balances 
relating to these credit facilities totaled $2.1 million and $2.7 million, respectively, as of December 31, 2016 and 2015. 
Compensating balances are classified as restricted cash and investments on our consolidated balance sheets. See Note 10 
of Notes to Consolidated Financial Statements in Item 8 of Part II of this Report. 

As of December 31, 2016, we had two loan arrangements with the Bank of Tokyo-Mitsubishi UFJ, Ltd. 

(collectively the “Mitsubishi Bank Term Loans”). One of Mitsubishi Bank Term Loans requires interest only payments 
until the maturity date of February 23, 2018, with a lump sum payment of the aggregate principal amount on the maturity 
date while the other requires equal monthly payments of principal equal to 8,333,000 JPY until the maturity date of 
February 25, 2025, with a lump sum payment of the balance of 8,373,000 JPY on the maturity date. Interest on the 
Mitsubishi Bank Loans accrues and is paid monthly based upon the annual rate of the monthly Tokyo Interbank Offer 
Rate (TIBOR) plus 1.40% and is secured by real estate collateral. As of December 31, 2016, our total outstanding 
balance under the two Mitsubishi Banks Term Loans was 1.3 billion JPY (approximately $11.3 million). See Note 10 of 
Notes to Consolidated Financial Statements in Item 8 of Part II of this Report. 

From time to time we accept notes receivable in exchange for accounts receivable from certain of our customers in 

China. These notes receivable are non-interest bearing and are generally due within six months.  Historically, we have 
collected on the notes receivable in full at the time of maturity.  

We believe that our existing cash, cash equivalents and cash flows from our operating activities will be sufficient 
to meet our anticipated cash needs for at least the next 12 months.  Our future capital requirements will depend on many 
factors including our growth rate, the timing and extent of spending to support development efforts, the expansion of 
sales and marketing activities, the introduction of new and enhanced products, the costs to increase our manufacturing 
capacity and our foreign operations, the continuing market acceptance of our products and acquisitions of businesses and 
technology. In the event that additional financing is required from outside sources, we may not be able to raise it on 
terms acceptable to us or at all. If we are unable to raise additional capital when desired, our business, operating results 
and financial condition would be adversely affected.

Rusnano Rights Agreement 

Under our amended rights agreement, dated June 30, 2015, with Rusnano, one of our principal stockholders, we 

agreed to make a $30.0 million investment commitment (the “Investment Commitment”) toward our Russian operations. 
The Investment Commitment can be partially satisfied by cash and/or non-cash investment inside or outside of Russia. 
Our $18.8 million investment milestone for 2016 was met as of December 31, 2016. If certain of the Investment 
Commitments are not achieved in the indicated time frames through 2019, we have the ability to exit our Russian 
operations by paying an exit fee of up to $3.5 million. See Note 12, Commitments and contingencies, in Notes to 
Consolidated Financial Statements in Item 8 of Part II of this Report for additional information.

In 2016, net cash provided by operating activities was $53.8 million, a $27.7 million increase compared to 2015. 

The increase was primarily due to a $27.8 million increase in accounts payable due to timing of payments, a $13.6 
million increase attributable to inventory shipments driven by product demand and a $1.8 million increase in net income 
net of non-cash adjustments, partially offset by a $9.5 million decrease related to higher prepaid and other assets 
primarily due to a reduction in prepaid taxes in 2015, a $6.0 million decrease related to lower accrued and other 
liabilities balance primarily due to variable compensation accrual for 2015 that did not recur in 2016. 

In 2015, net cash provided by operating activities was $26.1 million, a $26.6 million increase compared to 2014. 

The increase was primarily due to a $23.4 million increase in net income, a $15.8 million increase driven by lower 
accounts receivable due to collections, a $5.7 million increase in accrued and other liabilities, a $4.2 million increase in 
prepaid and other assets, partially offset by a $19.9 million decrease related to inventory increases due to anticipated 
demand and a $5.7 million decrease in accounts payable due to timing of payments. 

In 2014, net cash used in operating activities was $0.5 million, which was a $5.0 million decrease compared to the 

$4.5 million cash provided by operating activities in 2013. The decrease was primarily attributable to an increase in 
accounts receivable due to higher revenue in 2014 while days sales outstanding improved compared to 2013. Additional 
contributing factors to the increase in net cash used in operating activities included lower accounts payable related 
payments and higher accrued and other liabilities in 2013 and an increase in prepaid expenses and other assets in 2014 
primarily attributable to sales tax refunds, partially offset by a reduction in net loss, net of non-cash charges, and a lower 
inventory level in 2014, compared to 2013. 

Investing activities  

In 2016, net cash used in investing activities was $49.5 million, a $27.6 million increase compared to $21.9 million 
used in 2015. The increase in net cash used in investment activities was primarily attributable to a $45.6 million increase 
in purchased marketable securities, a $34.9 million increase in property, plant and equipment purchases to meet our 
product demand, a $10.8 million increase as a result of a large restricted cash decrease in 2015 and a $1.6 million 
increase due to foreign currency hedge settlement payments, partially offset by a $45.7 million increase in proceeds from 
sales of marketable securities, a $19.1 million increase in proceeds from maturity of securities and a $0.4 million 
reduction in cash used in business acquisition compared to 2015.

In 2015, net cash used in investing activities was $21.9 million, an $8.0 million increase compared to $13.9 million 
used in 2014. The increase in net cash used in investment activities was primarily attributable to a $27.5 million increase 
in purchased marketable securities, a $5.8 million increase in property, plant and equipment purchases and a $5.4 million 
reduction in proceeds from maturity of securities, partially offset by a $21.0 million increase as a result of decreases in 
restricted cash balances and an $8.5 million increase in proceeds from sales of marketable securities. 

In 2014, net cash used in investing activities was $13.9 million, a $27.2 million decrease compared to the $13.3 
million provided by investing activities in 2013, primarily due to a $85.1 million decrease in proceeds from sales and 
maturities of marketable securities and an $11.4 million increase in restricted cash, partially offset by a $49.2 million 
decrease in marketable securities purchases and a $8.5 million decrease in capital equipment purchases. In addition, net 
cash used in acquisition was $1.5 million in 2014 for the asset purchase arrangement with EMCORE, compared to a 
payment of $12.7 million for the acquisition of NeoPhotonics Semiconductor in 2013.  

Financing activities  

In 2016, net cash provided by financing activities was $3.5 million, a $26.1 million decrease compared to $29.6 

million in 2015. The decrease was primarily attributable to a $45.8 million decrease largely attributable to the $45.6 
million net proceeds from our follow-on public offering in 2015, a $5.2 million decrease related to lower net proceeds 
from issuance of notes payable and a $2.1 million decrease in repayments of bank and acquisition-related loans, partially 
offset by a $14.9 million increase in proceeds from bank loans and a $7.5 million increase due to lower repayments of 
notes payable and a $3.9 million increase due to higher proceeds from exercise of stock options and issuance of stock 
under employee stock purchase plan primarily attributable higher average common stock price in 2016 compared to 
2015. 

In 2015, net cash provided by financing activities was $29.6 million, a $26.6 million increase compared to 2014. 

The increase was primarily attributable to a $62.2 million increase in net proceeds from bank and acquisition-related 
loans, a $45.6 million net proceeds from issuance of common stock in public offering, partially offset by a $75.6 million 
decrease in loans and acquisition-related loan payments, a $4.0 million decrease in proceeds from issuance of notes 
payable and a $3.4 million decrease in the repayments of notes payable. 

In 2014, net cash provided by financing activities was $3.0 million, an increase of $0.5 million compared to $2.5 

million in 2013. The increase was primarily attributable to a $5.7 million increase in proceeds from notes payable 
issuances and a $5.7 million decrease in repayment of bank loans, partially offset by an $8.4 million decrease in proceeds 
from bank loans, a $2.0 million payment for the contingent consideration liability related to the Santur acquisition and a 
$0.6 million decrease in net proceeds from exercises of stock options and issuance of restricted stock units.

Recent accounting pronouncements  

See Note 2, Summary of Significant Accounting Policies, in Notes to the Consolidated Financial Statements in Item 

8 of Part II of this Report, for a full description of recent accounting pronouncements, including the expected dates of 
adoption and estimated effects on financial condition and results of operations, which is incorporated herein by 
reference.  

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK  

Interest rate fluctuation risk  

The primary objective of our investment activities is to preserve principal while at the same time maximizing the 
income we receive from our investments without significantly increasing risk. To achieve this objective, we invest our 
excess cash in a variety of securities, including U.S. government agency securities, corporate notes and bonds and money 
market funds meeting certain criteria. These securities are classified as available-for-sale which are recorded on the 
balance sheet at fair value. We have determined that the gross unrealized gains or losses on the available-for-sale 
securities at December 31, 2016 are temporary in nature. We may sell these marketable securities investments in the 
future to fund future operating needs.  

As of December 31, 2016 we had $23.8 million outstanding under our U.S. credit facilities and $11.3 million 
outstanding under our term loans with the Mitsubishi Bank, which were subject to fluctuations in interest rates. For the 
year ended December 31, 2016, a hypothetical 10% increase in the interest rate could result in immaterial additional 
annual interest expense. The hypothetical assumptions made above will be different from what actually occurs in the 
future. Furthermore, the computations do not anticipate actions that may be taken by our management should the 
hypothetical market changes actually occur over time. As a result, actual impacts on our results of operations in the 
future will differ from those quantified above.  

Foreign currency exchange risk  

Foreign currency exchange rates are subject to fluctuation and may cause us to recognize transaction gains and 
losses in our statements of operations. A large portion of our business is conducted through our subsidiaries in China, 
whose functional currency is the RMB and Japan, whose functional currency is the JPY. To the extent that transactions 
by these subsidiaries are in currencies other than their functional currencies, we bear the risk that fluctuations in the 
exchange rates of the RMB and JPY in relation to other currencies could increase our costs and expenses. During the 
year ended December 31, 2016, we recognized net foreign currency transaction losses of $0.1 million. We use the U.S. 
dollar as the reporting currency for our consolidated financial statements. Any significant revaluation of the RMB or JPY 
may materially and adversely affect our results of operations upon translation of these subsidiaries’ financial statements 
into U.S. dollars. While we generate a significant portion of our revenue in U.S. dollars, a significant portion of our cost 
of goods sold are in RMB. Therefore appreciation in RMB against the U.S. dollar would negatively impact our cost of 
goods sold upon translation to U.S. dollars. For example, for the year ended December 31, 2016, a 10% appreciation in 
RMB against the U.S. dollar would have resulted in an approximately $1.5 million increase in our cost of goods sold.  

Effective July 1, 2016, we have entered into hedging transactions to reduce the short-term impact of foreign 
currency fluctuations. However, the availability and effectiveness of these hedging transactions may be limited and we 
may not be able to successfully hedge our exposure. In addition, our currency exchange variations may be magnified by 
any Chinese exchange control regulations that restrict our ability to convert RMB into foreign currency.  

Inflation risk  

Inflationary factors, such as increases in our cost of goods sold and operating expenses, may adversely affect our 

results of operations. Although we do not believe that inflation has had a material impact on our financial position or

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  

To the Board of Directors and Stockholders of NeoPhotonics Corporation 
San Jose, California 

We have audited the accompanying consolidated balance sheets of NeoPhotonics Corporation and subsidiaries (the 
"Company") as of December 31, 2016 and 2015, and the related consolidated statements of operations, comprehensive 
loss, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2016. These 
financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on 
these financial statements based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United 
States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the 
financial statements are free of 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, such consolidated financial statements present fairly, in all material respects, the financial position of 
NeoPhotonics Corporation and subsidiaries as of December 31, 2016 and 2015, and the results of their operations and 
their cash flows for each of the three years in the period ended December 31, 2016, in conformity with accounting 
principles generally accepted in the United States of America. 

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 the criteria established 
in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the 
Treadway Commission and our report dated March 16, 2017 expressed an adverse opinion on the Company's internal 
control over financial reporting because of a material weakness.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1. The Company and basis of presentation  

Business and organization  

NeoPhotonics Corporation and its subsidiaries (NeoPhotonics or the Company) develops, manufactures and sells 

optoelectronic products that transmit, receive and switch high speed digital optical signals for communications networks. 
The Company sells its products worldwide, primarily to leading network equipment manufacturers.   

Certain Significant Risks and Uncertainties 

The Company operates in a dynamic industry and, accordingly, can be affected by a variety of factors.  For 
example, any of the following areas could have a negative effect on the Company in terms of its future financial position, 
results of operations or cash flows: the general state of the U.S. and world economies, the highly cyclical nature of the 
industries the Company serves; the loss of any of a small number of its larger customers; ability to obtain additional 
financing; inability to meet certain debt covenants; failure to successfully integrate completed acquisitions; fundamental 
changes in the technology underlying the Company’s products; the hiring, training and retention of key employees; 
successful and timely completion of product design efforts; and new product design introductions by competitors.  

Consolidation  

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

Intercompany accounts and transactions have been eliminated in consolidation. 

2. Summary of significant accounting policies  

Use of estimates  

The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“U.S. 

GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and 
liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported 
revenue and expenses during the reporting period. Significant estimates made by management include: the useful lives of 
property, plant and equipment and intangible assets as well as future cash flows to be generated by those assets; fair 
values of identifiable assets acquired and liabilities assumed in business combinations; allowances for doubtful accounts; 
valuation allowances for deferred tax assets; write off of excess and obsolete inventories; the valuation of the Rusnano 
payment derivative and the valuations and recognition of stock-based compensation, among others. Actual results could 
differ from these estimates.  

Concentration of credit risk and significant customers  

Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and 
cash equivalents and trade accounts receivable. The Company’s investment policy requires cash and cash equivalents to 
be placed with high-credit quality institutions and limits on the amount of credit risk from any one issuer. The Company 
performs ongoing credit evaluations of its customers’ financial condition whenever deemed necessary and generally does 
not require collateral. The Company maintains an allowance for doubtful accounts based upon the expected collectability 
of all accounts receivable, which takes into consideration an analysis of historical bad debts, specific customer 
creditworthiness and current economic trends.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

For the year ended December 31, 2016, two customers accounted for 50% and 15% of the Company’s total 
revenue.  For the year ended December 31, 2015, two customers accounted for 44% and 21% of the Company’s total 
revenue.  For the year ended December 31, 2014, three customers accounted for 38%, 15% and 10% of the Company’s 
total revenue. The percentage of revenue from top ten customers was 91%, 91% and 88% for the years ended December 
31, 2016, 2015 and 2014, respectively. 

As of December 31, 2016, three customers accounted for approximately 42%, 12% and 12%, respectively, of the 

Company’s total accounts receivable. As of December 31, 2015, one customer accounted for 59% of the Company’s 
total accounts receivable. 

Restricted cash  

As a condition of the notes payable lending arrangements and the line of credit facilities, the Company is required 

to keep a compensating balance at the issuing banks. In addition, the Company also maintained restricted cash in 
connection with the asset purchase agreement executed in December 2016, see Note 8. These balances have been 
excluded from the Company’s cash and cash equivalents balance and are classified as restricted cash in the Company’s 
consolidated balance sheets. As of December 31, 2016 and 2015, the amount of restricted cash was $4.1 million and $2.7 
million, respectively.  

Cash, cash equivalents and investments  

Highly liquid investments with a maturity of 90 days or less at the date of purchase are considered cash 

equivalents, with the exception of money market funds and commercial paper which are classified as short-term 
investments. Marketable securities are reported at fair value and are classified as available-for-sale investments in our 
current assets because they represent investments of cash available for current operations and for strategic reasons. As a 
result, the Company recorded all its marketable securities in short-term investments regardless of the contractual 
maturity date of the securities. 

The Company regularly reviews its investment portfolio to identify and evaluate investments that have indications 
of possible impairment. Factors considered in determining whether a loss is other-than-temporary include: the length of 
time and extent to which the fair market value has been lower than the cost basis, the financial condition and near-term 
prospects of the investee, credit quality, likelihood of recovery, and the Company’s ability to hold the investment for a 
period of time sufficient to allow for any anticipated recovery in fair market value.  

Unrealized gains and losses, net of tax, are included in accumulated other comprehensive loss as a separate 
component of stockholders’ equity on the consolidated balance sheets. The amortization of premiums and discounts on 
the investments, and realized gains and losses on available-for-sale securities are included in other income, net in the 
consolidated statements of operations. The Company uses the specific-identification method to determine cost in 
calculating realized gains and losses upon the sale of its marketable securities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

Fair Value Measurements  

Fair value is defined as the price at which an asset could be exchanged in a current transaction between 

knowledgeable, willing parties. A liability’s fair value is defined as the amount that would be paid to transfer the liability 
to a new obligor, not the amount that would be paid to settle the liability with the creditor. Where available, fair value is 
based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or 
inputs are not available, valuation models are applied. These valuation techniques involve some level of management 
estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and 
the instruments’ complexity. Valuation techniques used to measure fair value must maximize the use of observable 
inputs and minimize the use of unobservable inputs. The authoritative accounting guidance describes a fair value 
hierarchy based on three levels of inputs that may be used to measure fair value, of which the first two are considered 
observable and the last is considered unobservable. These levels of inputs are as follows:  

Level 1—Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at 
the measurement date.  

Level 2—Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the 
asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for 
identical or similar assets or liabilities in markets that are not active.  

Level 3—Unobservable inputs that reflect management’s best estimate of what market participants would use in 
pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation 
technique and the risk inherent in the inputs to the model.  

For marketable securities measured at fair value using Level 2 inputs, we review trading activity and pricing for 

these investments as of the measurement date. When sufficient quoted pricing for identical securities is not available, we 
use market pricing and other observable market inputs for similar securities obtained from various third party data 
providers. These inputs either represent quoted prices for similar assets in active markets or have been derived from 
observable market data.  

Accounts receivable  

Accounts receivable include trade receivables and notes receivable from customers. The notes are generally due 
within six months. The Company receives notes receivable in exchange for accounts receivable from certain customers 
in China that are secured by the customer’s affiliated financial institution. 

An allowance for doubtful accounts is calculated based on the aging of the Company’s trade receivables, historical 

experience, and management judgment. The Company writes off trade receivables against the allowance when 
management determines a balance is uncollectible and is no longer actively pursuing collection of the receivable. 

Inventories  

Inventories consist of on-hand raw materials, work-in-progress inventories and finished goods. Raw materials and 
work-in-progress inventories are stored mainly on the Company’s premises. Finished goods are stored on the Company’s 
premises as well as on consignment at certain customer sites.  

Inventories are stated at the lower of standard cost, which approximates actual cost determined on the weighted 

average basis, or market value. Inventories are recorded using the first-in, first-out method. The Company routinely 
evaluates quantities and values of inventories in light of current market conditions and market trends, and records a 
write-down for quantities in excess of demand and product obsolescence. The evaluation may take into consideration 
historic usage, expected demand, anticipated sales price, new product development schedules, the effect new products 
might have on the sale of existing products, product obsolescence, customer concentrations, product merchantability and 

68 

 
 
 
 
 
 
 
 
 
 
 
 
NEOPHOTONICS CORPORATION 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

other factors. Market conditions are subject to change and actual consumption of inventory could differ from forecasted 
demand. The Company also regularly reviews the cost of inventories against their estimated market value and records a 
lower of cost or market write-down for inventories that have a cost in excess of estimated market value, resulting in a 
new cost basis for the related inventories which is not reversed.  

Business Combinations  

We allocate the fair value of purchase consideration to the tangible and intangible assets acquired and liabilities 

assumed based on their estimated fair values as of the close of acquisition. The excess of the fair value of purchase 
consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. When determining 
the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions 
through established and generally accepted valuation techniques.  

Fair value estimates are based on the assumptions management believes a market participant would use in pricing 
the asset or liability. Critical estimates in valuing certain intangible assets include, but are not limited to, future expected 
cash flows from customer relationships and acquired patents and developed technology; and discount rates. 
Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently 
uncertain and unpredictable and, as a result, actual results may differ from estimates.  

Amounts recorded in a business combination may change during the measurement period, which is a period not to 

exceed one year from the date of acquisition, as additional information about conditions existing at the acquisition date 
becomes available. 

Goodwill  

Goodwill is reviewed for impairment annually in the fourth fiscal quarter or more frequently if events or changes 

in circumstances indicate that the carrying value of goodwill may not be recoverable. The Company will assess the 
qualitative factors to determine whether it is more likely than not that the fair value of its reporting unit is less than its 
carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment. If the 
Company determines that it is more likely than not that its fair value is less than its carrying amount, then the two-step 
goodwill impairment test is performed. The first step, identifying a potential impairment, compares the fair value of the 
reporting unit with its carrying amount. If the carrying amount exceeds its fair value, the second step would need to be 
performed; otherwise, no further steps are required. The second step, measuring the impairment loss, compares the 
implied fair value of the goodwill with the carrying amount of the goodwill. Any excess of the goodwill carrying amount 
over the implied fair value is recognized as an impairment loss, and the carrying value of goodwill is written down to fair 
value. The Company had no goodwill impairment in 2016 or 2015.  

Long-lived assets  

Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. Repairs and 

maintenance costs are expensed as incurred. Depreciation and amortization are computed using the straight-line method 
over the following estimated useful lives:  

Buildings 
Machinery and equipment 
Furniture, fixtures and office equipment 
Software 
Leasehold improvements 

    20-30 years 
   2-7 years 
   3-5 years 
   5-7 years 
   life of the asset or lease term, if shorter

Intangible assets acquired in a business combination are recorded at fair value. Identifiable finite-lived intangible 

assets are amortized over the period of estimated benefit using the straight-line method, reflecting the pattern of 

69 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
NEOPHOTONICS CORPORATION 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

economic benefits associated with these assets. The estimated useful lives of the Company’s finite-lived intangible assets 
generally range from two to seven years. The acquired land use rights in China have an estimated useful life of 45 years.  

Assets held for sale are measured at the lower of carrying value or the fair value less cost to sell. The carrying 

value of intangible assets and other long-lived assets is reviewed on a regular basis for the existence of facts or 
circumstances, both internally and externally, that may suggest impairment. Some factors which the Company considers 
to be triggering events for impairment review include a significant decrease in the market value of an asset, a significant 
change in the extent or manner in which an asset is used, a significant adverse change in the business climate that could 
affect the value of an asset, an accumulation of costs for an asset in excess of the amount originally expected, a current 
period operating loss or cash flow decline combined with a history of operating loss or cash flow uses or a projection that 
demonstrates continuing losses and a current expectation that, it is more likely than not, a long-lived asset will be 
disposed of at a loss before the end of its estimated useful life.  

If one or more of such facts or circumstances exist, the Company will evaluate the carrying value of long-lived 

assets to determine if impairment exists by comparing it to estimated undiscounted future cash flows over the remaining 
useful life of the assets. If the carrying value of the assets is greater than the estimated future cash flow, the assets are 
written down to the estimated fair value. The Company’s cash flow estimates contain management’s best estimates, 
using appropriate and customary assumptions and projections at the time. Any write-down would be treated as a 
permanent reduction in the carrying amount of the asset and an operating loss would be recognized. 

There were no asset impairment charges in 2016. The Company recorded asset impairment charges of $0.4 million 

in 2015 related to certain held-for-sale property, plant and equipment and $1.1 million in 2014 related to certain 
leasehold improvements.  

Revenue recognition  

Revenue is derived from the sale of the Company’s products. The Company recognizes revenue provided that 
persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectability 
is reasonably assured. Contracts and/or customer purchase orders are used to determine the existence of an arrangement. 
Delivery is considered to have occurred when title and risk of loss have transferred to the customer. The price is equal to 
the amount invoiced to the customer and is not subject to adjustment and customers do not have the right of return. The 
Company evaluates the creditworthiness of its customers to determine that appropriate credit limits are established prior 
to the acceptance of an order.  

Revenue is recognized when the product is delivered and title have transferred to the buyer. The Company 
generally bears all costs and risks of loss or damage to the goods up to that point. Revenue related to the sale of 
consignment inventory at customer vendor managed locations is not recognized until the product is pulled from 
inventory stock by customers. In instances where acceptance of the product or solutions is specified by the customer, 
revenue is deferred until such required acceptance criteria have been met. Shipping and handling costs are included in 
the cost of goods sold. The Company presents revenue net of sales taxes and any similar assessments.  

Product warranties  

The Company generally provides warranties to cover defects in workmanship, materials and manufacturing for a 
period of one to three years to meet the stated functionality as agreed to in each sales arrangement. Products are tested 
against specified functionality requirements prior to delivery, but the Company nevertheless from time to time 
experiences claims under its warranty guarantees. The Company accrues for estimated warranty costs under those 
guarantees based upon historical experience, and for specific items, at the time their existence is known and the amounts 
are determinable.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

Research and development  

Research and development expense consists of personnel costs, including stock-based compensation expense, for 

the Company’s research and development personnel and product development costs, including engineering services, 
development software and hardware tools, depreciation of capital equipment and facility costs. Research and 
development costs are expensed as incurred.  

Advertising costs  

Advertising costs are expensed as incurred and, to date, have not been significant.  

Stock-based compensation  

The Company grants stock-based awards to employees, consultants and directors. The stock-based awards, 
including stock options, restricted stock units, employee stock purchase rights, stock appreciation units and market-based 
awards, are accounted for at estimated fair values. Vesting of stock-based awards is generally subject to the grantee’s 
continuing service to the Company.   

The Company generally determines the fair value of stock options and stock appreciation rights utilizing the 
Black-Scholes-Merton option-pricing model, or a lattice-binomial option-pricing model for stock-based awards with a 
market condition. The fair value of employee grants is measured on the date of grant and then recognized over the period 
during which an employee is required to provide services in exchange for the award, known as the requisite service 
period (usually the vesting period) on a straight-line basis. The fair value of non-employee grants is measured on the date 
of grant and then marked to market until vest dates and then recognized over the requisite service period. 

The Company records expense and an equal adjustment to the liability for stock appreciation units equal to the fair 
value of the vested portion of the awards as of each period end. Each reporting period thereafter, compensation expense 
will be recorded based on the remaining service period and the then fair value of the award until vesting of the award is 
completed. After vesting is completed, the Company will continue to re-measure the fair value of the liability each 
reporting period until the award is exercised or expires, with changes in the fair value of the liability recorded in the 
consolidated statements of operations.  

Restricted stock units are valued at the closing sales price as quoted on the New York Stock Exchange on the date 
of grant, and are converted into shares of common stock upon vesting on a one-for-one basis. The compensation expense 
related to the restricted stock units is determined using the fair value of common stock on the date of grant, and the 
expense is recognized on a straight-line basis over the vesting period.  

Employee stock purchase rights are accounted for at fair value, utilizing the Black-Scholes-Merton option-pricing 
model. The expense for each purchase period is recognized on a straight-line basis over the requisite service period, from 
the beginning of the offering period through the respective purchase date.  

Stock-based compensation expense for modified stock-based awards are recognized using the pool approach, 
under which the remaining compensation cost from the original awards plus the incremental costs, if any, of the related 
modified awards is recognized in its entirety over the remaining portion of the requisition service period of the 
corresponding modified awards. 

Stock-based compensation expense recognized at fair value includes the impact of estimated forfeitures. The 
Company estimates future forfeitures at the date of grant and revises the estimates, if necessary, in subsequent periods if 
actual forfeitures differ from those estimates.

NEOPHOTONICS CORPORATION 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

Income taxes  

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are 
recognized for the future tax consequences attributable to differences between the carrying amounts of existing assets 
and liabilities in the financial statements and their respective tax bases, and operating loss and tax credit 
carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable 
income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred 
tax assets and liabilities from a change in tax rates is recognized in the consolidated statement of operations in the period 
that includes the enactment date.  

The Company operates in various tax jurisdictions and is subject to audit by various tax authorities. In preparing 

the Company’s consolidated financial statements, the Company is required to estimate its taxes in each of the 
jurisdictions in which it operates. The Company estimates actual current tax exposure as well as assesses temporary 
differences resulting from different treatment of items, such as accruals and allowances not currently deductible for tax 
purposes. These differences result in deferred tax assets which represent future tax benefits to be received when certain 
expenses previously recognized in the financial statements become deductible expenses under applicable income tax 
laws, or loss credit carryforwards are utilized.  

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that 
some portion or all of a deferred tax asset will be realized. The ultimate realization of deferred tax assets is dependent 
upon the generation of future taxable income during the periods in which those temporary differences become 
deductible. A valuation allowance is recorded for loss carryforwards and other deferred tax assets where it is more likely 
than not that such deferred tax assets will not be realized. The Company classifies its net deferred tax assets as other 
long-term assets and deferred tax liabilities as noncurrent liabilities on its consolidated balance sheet.  

Foreign currency  

Generally the functional currency of the Company’s international subsidiaries is the local currency. The Company 
translates the financial statements of these subsidiaries to U.S. dollars using month-end rates of exchange for assets and 
liabilities, and average rates of exchange for revenue, costs, and expenses. Translation gains and losses are recorded in 
accumulated other comprehensive income (loss) as a component of stockholders’ equity. Effective July 1, 2016, the 
Company has established a hedging program using monthly forward exchange contracts as economic hedges to protect 
against volatility of foreign exchange rate exposure of its net intercompany activities based on a cost-benefit analysis that 
considers that magnitude of the exposure, the volatility of the exchange rate and the cost of the hedging instruments. The 
forward contracts are not designated for hedge accounting and are marked to market at fair value and reported as either 
other current assets or accounts payable. Any changes in the fair value are recorded as foreign exchange gain (loss) and 
help mitigate the changes in the value of the underlying net intercompany balances. In 2016, the Company recognized a 
$1.6 million loss relating to its foreign currency contracts within other income, net. Net foreign exchange gain (loss) was 
($0.1) million, $3.4 million, and $3.1 million in 2016, 2015, and 2014, respectively. These gains and losses were 
recorded as other income (expense), net in the Company’s consolidated statements of operations. The Company presents 
the cash flows relating to these foreign exchange contracts as investing activities in its consolidated statements of cash 
flows.  

Net income (loss) per share  

Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of 

common shares outstanding for the period. Diluted net income (loss) per share is calculated by dividing net income (loss) 
by the weighted average number of common shares and potential dilutive common share equivalents outstanding during 
the period if the effect is dilutive.

Recent accounting pronouncements  

In November 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 
("ASU") 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASC 2016-18”). This standard provides 
guidance on the classification and presentation of restricted cash in the statement of cash flows and must be applied 
retrospectively. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017. Early adoption is 
permitted. The Company is in the process of evaluating the impact of adoption on its consolidated financial statements. 

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other 

Than Inventory (“ASU 2016-16”). This standard provides guidance on the tax accounting for the transferring and 
receiving entities upon transfer of an asset. ASU 2016-16 is effective for the Company’s interim and annual periods 
beginning after December 15, 2017 and should be applied on a modified retrospective basis. Early adoption is permitted. 
The Company is in the process of evaluating the impact of adoption on its consolidated financial statements.  

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain 
Cash Receipts and Cash Payments (“ASU 2016-15”). This standard provides guidance on the classification of certain 
cash receipts and payments in the statement of cash flows.  It is effective, retrospectively, for the Company’s annual and 
interim reporting periods beginning after December 15, 2017 or prospectively from the earliest data practicable if 
retrospective application is impracticable. Early adoption is permitted. The Company is in the process of evaluating the 
impact of adoption on its consolidated financial statements.  

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of 
Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 amends existing guidance on the impairment of 
financial assets and adds an impairment model that is based on expected losses rather than incurred losses and requires 
an entity to recognize as an allowance its estimate of expected credit losses for its financial assets. An entity will apply 
this guidance through a cumulative-effect adjustment to retained earnings upon adoption (a modified-retrospective 
approach) while a prospective transition approach is required for debt securities for which an other-than-temporary 
impairment had been recognized before the effective date. It is effective for the Company’s annual and interim reporting 
periods beginning after December 15, 2019. Early adoption is permitted. The Company is in the process of evaluating 
the impact of adoption on its consolidated financial statements. 

In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements 

to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the 
accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and 
statutory tax withholding requirements, as well as classification in the statement of cash flows. Early adoption is 
permitted. This guidance was effective, and adopted by the Company, on January 1, 2017. The impact on the Company’s 
consolidated financial statements upon the adoption of this standard was immaterial.  

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”).  ASU 2016-02 introduces 
a lessee model that requires recognition of assets and liabilities arising from qualified leases on the consolidated financial 
statements and the qualitative and quantitative disclosures about lease transactions. It is effective for interim and annual 
periods beginning after December 15, 2018. Early adoption is permitted. The Company is in the process of evaluating 
the impact of adoption on its consolidated financial statements. 

In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition 

and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”).  ASU 2016-01 revises an entity’s 
accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation 
of certain fair value changes for financial liabilities measured at fair value.  It also amends certain disclosure 
requirements associated with the fair value of financial instruments and is effective for the Company’s annual and

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory 

(“ASU 2015-11”). ASU 2015-11 requires entities to measure most inventory “at the lower of cost and net realizable 
value” for inventories that are not measured by using either the last-in, first-out method or the retail inventory method. 
This guidance is effective, and adopted by the Company, on January 1, 2017. Early adoption is permitted. The impact on 
the Company’s consolidated financial statements upon the adoption of this standard was immaterial. 

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The 
standard, along the amendments issued in 2016 and 2015, provides companies with a single model for use in accounting 
for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including 
industry-specific revenue guidance. The core principle of the model is to recognize revenue when control of the goods or 
services transfers to the customer, as opposed to recognizing revenue when the risks and rewards transfer to the customer 
under the existing revenue guidance. This standard, as amended, is effective for annual and interim periods beginning 
after December 15, 2017 and permits entities to early adopt for annual and interim reporting periods beginning after 
December 15, 2016. Companies are permitted to either apply the requirements retrospectively to all prior periods 
presented, or apply the requirements in the year of adoption, through a cumulative adjustment.  The Company expects to 
adopt this standard, as amended, effective January 1, 2018 and is in the process of evaluating the impact of adoption on 
its consolidated financial statements.

The Company offers a Non-Qualified Deferred Compensation Plan (“NQDC Plan”) to a select group of its highly 
compensated employees to provide participants the opportunity to defer payment of certain compensation as defined in 
the NQDC Plan. A Rabbi Trust has been established to fund the NQDC Plan obligation, which was fully funded at 
December 31, 2016. The assets held by the Rabbi Trust are in the form of exchange traded mutual funds and are included 
in the Company’s other long-term assets on its consolidated balance sheets at December 31, 2016 and 2015. Level 1 
assets are determined by using quoted prices in active markets for identical assets. The fair values of Level 2 assets are 
priced based on quoted market prices for similar instruments or non-binding market prices that are corroborated by 
observable market data using inputs such as benchmark yields, broker quotes and other similar data.

The fair value of the Rusnano payment derivative is based on the Company’s estimate (see Note 12). The fair 
values of the foreign currency forward contracts are based on quoted market rates and market observable data for similar 
instruments. There were no transfers between levels of the fair value hierarchy during the periods presented. 

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis  

In 2016, there were no assets or liabilities measured at fair value on a nonrecurring basis. In 2015, the Company 

wrote off $0.2 million of property, plant and equipment and $0.2 million of held-for-sale assets recognized and 
recognized asset impairment charges of $0.4 million within operating expenses (Level 3). In 2014, certain leasehold

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

improvements were written off, resulting in a $1.1 million asset impairment charge within operating expenses (Level 3). 
These assets were measured at fair value due to events or circumstances the Company identified as having significant 
impact on their fair value during the respective periods. To arrive at the valuation of these assets, the Company 
considered the discounted cash flows and categorized the fair value measurement as Level 3 as significant unobservable 
inputs were used in the valuation. 

Assets and Liabilities Not Measured at Fair Value  

The carrying values of cash, restricted cash, accounts receivable, accounts payable, notes payable and short-term 

borrowing approximate their fair values due to the short-term nature and liquidity of these financial instruments.  

The fair value of the Company’s long-term debt have been calculated using an estimate of the interest rate the 

Company would have had to pay on the issuance of liabilities with a similar maturity and discounting the cash flows at 
that rate which it considers to be a level 2 fair value measurement and was not materially different than the carrying 
value as of December 31, 2016 and 2015 as the interest rates approximated rates currently available to the Company. The 
fair values do not necessarily give an indication of the amount that the Company would currently have to pay to 
extinguish any of this debt.

6. Business Combinations  

EMCORE Corporation  

On January 2, 2015, the Company closed an acquisition of certain assets and assumed certain liabilities of the 
tunable laser product lines of EMCORE Corporation (“EMCORE”) for an original purchase price of $17.5 million, 
pursuant to the terms of the Asset Purchase Agreement between the parties dated October 22, 2014. Consideration for the 
transaction consisted of $1.5 million in cash and a promissory note (the “EMCORE Note”) of approximately $16.0 
million, which was subsequently adjusted to $15.5 million in connection with a True-Up Confirmation Agreement (the 
“True-Up Agreement”) executed by and between the Company and EMCORE on April 16, 2015. The final adjusted 
purchase price for the acquisition was approximately $17.0 million. 

The Company accounted for this acquisition as a business combination. With the acquisition of the EMCORE ultra 

narrow linewidth tunable laser products, the Company aims to strengthen its portfolio of High Speed Products. 

In connection with the acquisition, the Company incurred approximately $0.9 million in total acquisition-related 
costs related to legal, accounting and other professional services. The acquisition costs were expensed as incurred and 
included in operating expenses in the Company’s consolidated statement of operations. 

The fair values assigned to intangible assets acquired were based on valuations using estimates and assumptions 
provided by management, with the assistance of an independent third party appraisal firm. The excess purchase price 
over those fair values was recorded as goodwill. The Company used best estimates and assumptions as part of the 
purchase price allocation process to value assets acquired and liabilities assumed at the acquisition date and during the 
Company’s process of obtaining further information, further refined estimates and assumptions, including the acquired 
property, plant and equipment, prepaid and other current assets, which primarily consisted of held-for-sale assets and 
accounts payable. As a result, during the measurement period completed in 2015, the Company recorded adjustments 
related to the acquired net accounts receivable, the acquired net inventories, the assumed sales tax accrual and the 
acquired prepaid expenses and other current assets by immaterial amounts, and decreased goodwill by a corresponding 
net amount.Goodwill recorded consisted of a valuable assembled workforce and market synergy. The amounts assigned 
to goodwill are deductible for income tax purposes.

In November 2015 the Company closed an acquisition of the business and products of EigenLight Corporation for 

cash consideration of $0.4 million in an asset transaction.  The Company accounted for this as a business combination 
and the majority of the purchase price was allocated to inventory and property, plant and equipment.

In October 2014, the Company entered into a settlement agreement covering certain outstanding claims in 

connection with the acquisition of certain assets and assumed certain liabilities related to the semiconductor Optical 
Components Business Unit of LAPIS Semiconductor Co., Ltd., a wholly owned subsidiary of Rohm Co., Ltd (“LAPIS”)

Notes payable and Short-Term Borrowing 

The Company regularly issues notes payable to its suppliers in China in exchange for accounts payable. These 
notes are supported by non-interest bearing bank acceptance drafts issued under the Company’s existing line of credit 
facilities with banking institutions and are due three to six months after issuance. Compensating balance at a percentage 
of the total notes payable balance is required to be maintained at the issuing banks until the notes payable balance is 
settled. These credit facilities can be used for short-term loans which will bear interest at varying rates. 

At December 31, 2016, the Company’s subsidiary in China had three short-term line of credit facilities. Under the 
first credit facility, which has been renewed to expire in July 2019, RMB 120.0 million ($17.3 million) can be used for 
short-term loans or up to RMB 171.4 million ($24.7 million) can be used for bank acceptance drafts (with a 30% 
compensating balance requirement).  Under the second credit facility, which has been renewed to expire in September 
2017, the borrowing capacity has been increased to RMB 266.0 million ($38.3 million) for short-term loans or up to 
approximately RMB 380.0 million ($54.7 million) can be used for bank acceptance drafts (with a 30% compensating 
balance requirement). The third credit facility, executed in August 2016 and expires in July 2019, has a borrowing 
capacity of up to RMB 30.0 million (approximately $4.3 million) for short-term loans or up to approximately RMB 42.9 
million (approximately $6.2 million) for bank acceptance drafts (with a 30% compensating balance requirement).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

As of December 31, 2016 and 2015, the non-interest bearing bank acceptance drafts issued in connection with the 
Company’s notes payable to its suppliers in China under these line of credit facilities had an outstanding balance of $6.4 
million and $8.9 million, respectively, with compensating balances relating to these credit facilities totaling $2.1 million 
and $2.7 million, respectively. Compensating balances are classified as restricted cash on the Company’s consolidated 
balance sheets.  

In addition to the outstanding notes payable, three letters of credit totaling $1.6 million to its suppliers were issued 

in 2016 for equipment purchases in December 2016. These letters of credit require a 30% compensating balance 
requirement. As of December 31, 2016, the outstanding balance of the letters of credit was immaterial and was fully 
repaid in January 2017. 

In 2015, the Company’s subsidiary in China repaid in full its short-term advance financing agreements under its 

line of credit facilities.  

The Company has a credit agreement with the Comerica Bank as lead bank in the U.S. (the “Comerica Credit 

Agreement”). In 2015, the Comerica Credit Agreement was amended to refinance the then-outstanding Comerica term 
loan and increased the revolving credit line borrowing capacity to $30.0 million. In 2017, the Company further amended 
the Comerica Credit Agreement to extend the maturity to April 30, 2017 and removed the financial covenant related to 
EBDITA. Borrowings under the term loan bore interest at an interest rate option of a base rate as defined in the 
agreement plus 2.0% or LIBOR plus 3.0% while borrowings under the amended revolving credit facility bear interest at 
an interest rate option of a base rate as defined in the agreement plus 1.75% or LIBOR plus 2.75%. The base rate is the 
greater of (a) the effective prime rate, (b) the Federal Funds effective rate plus one percent, and (c) the daily adjusting 
LIBOR rate plus one percent. The Company is subject to covenant requirements, including restrictions to incur certain 
additional debt or to engage in specified transactions, the payment of dividends to its stockholders in the event of a 
default and is secured by substantially all of the Company’s U.S. assets, other than intellectual property assets. As of 
December 31, 2016, the Company was in compliance with the related covenants except for exceeding the capital 
expenditure limit for which a waiver was obtained subsequent to year end. 

The outstanding balance under the Comerica Credit Agreement was $23.8 million at each of December 31, 2016 

and 2015 and the rate on the LIBOR option was 3.37% and 2.99%, respectively.   

Acquisition-related  

In 2015, the Company repaid in full the $15.5 million note issued for the acquisition of the tunable laser products 

of EMCORE in January 2015 as well as the remaining balance of the 1,050 million Japanese Yen (the “JPY”) loan 
issued for the acquisition of NeoPhotonics Semiconductor in March 2013. 

Long-Term Debt 

On February 25, 2015, the Company entered into two loan agreements (collectively, the “Loan Arrangements”) 
with the Mitsubishi Bank that provided for (i) a term loan in the aggregate principal amount of 500 million Japanese Yen 
(the “JPY”) ($4.2 million) (the “Term Loan A”) and (ii) a term loan in the aggregate principal amount of one billion JPY 
($8.4 million) (the “Term Loan B” and together with the Term Loan A, the “Mitsubishi Bank Loans”). The Mitsubishi 
Bank Loans are secured by a mortgage on certain real property and buildings owned by our Japanese subsidiary. Interest 
on the Mitsubishi Bank Loans accrues based upon the annual rate of the monthly Tokyo Interbank Offer Rate (TIBOR) 
plus 1.40%. The Term Loan A requires interest only payments until the maturity date on February 23, 2018 and the 
aggregate principal amount is due upon the maturity date. The Term Loan B requires equal monthly payments of 
principal equal to 8,333,000 JPY until the maturity date on February 25, 2025, and the balance of 8,373,000 JPY is due 
upon maturity. Interest on the Term Loan B is accrued based upon monthly TIBOR plus 1.40% and is secured by real 
estate collateral. In conjunction with the execution of the Bank Loans, the Company paid a loan structuring fee, 
including consumption tax, of 40,500,000 JPY ($0.3 million).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

The Mitsubishi Bank Loans contain covenants applicable to the Company’s Japanese subsidiary, including 
restrictions on cessation in business, management, mergers or acquisitions. The Mitsubishi Bank Loans contain financial 
covenants relating to minimum net assets, maximum ordinary loss and a dividends covenant. The Company used a 
portion of the proceeds of the Mitsubishi Bank Loans to repay the then-outstanding loan related to the acquisition of 
NeoPhotonics Semiconductor, which had an outstanding principal and interest amount of approximately 710 million JPY 
($6.0 million) and for general working capital. As of December 31, 2016, the outstanding principal balance under the 
Mitsubishi Bank Loans was approximately 1.3 billion JPY (approximately $11.3 million) and the Company was in 
compliance with the related covenants.

In connection with its acquisition of NeoPhotonics Semiconductor in 2013, the Company assumed responsibility 

for two defined benefit plans that provide retirement benefits to its NeoPhotonics Semiconductor employees in Japan: the 
Retirement Allowance Plan (“RAP”) and the Defined Benefit Corporate Pension Plan (“DBCPP”). The RAP is an 
unfunded plan administered by the Company.  Effective February 28, 2014, the DBCPP was converted to a defined 
contribution plan (“DCP”).  In May 2014, LAPIS transferred approximately $2.0 million into the newly formed DCP 
which was the allowable amount that can be transferred according to the Japanese regulations. LAPIS also paid the 
Company approximately $0.3 million in connection with the conversion of the plan.  Additionally, the Company 
transferred the net unfunded projected benefit obligation amount from the DBCPP to the RAP and froze the RAP benefit 
at the February 28, 2014 amount.  Under the RAP, lump sum benefits are provided upon retirement or upon certain 
instances of termination. In 2014, the Company reclassified $0.2 million and $0.1 million from accumulated other 
comprehensive income to cost of goods sold and operating expenses, respectively.

401(k) Plan 

The Company maintains a savings and retirement plan qualified under Section 401(k) of the Internal Revenue 
Code of 1986, as amended (the "IRC"). The Company currently matches a portion of all eligible employee contributions 
which vest immediately. The Company’s matching contributions to the plan totaled $0.4 million, $0.3 million and $0.3 
million, respectively, for the years ended December 31, 2016, 2015, and 2014. 

12. Commitments and contingencies  

Leases  

The Company leases various facilities under non-cancelable operating leases. As of December 31, 2016, the future 

minimum commitments under the Company’s non-cancelable operating leases are as follows (in thousands):

The total minimum lease commitment amount above does not include minimum sublease rent income of $1.0 

million receivable in the future under non-cancelable sublease agreements. 

The Company recognizes rent expense on a straight-line basis over the lease period. Rent expense under the 

Company’s operating leases was $2.4 million, $2.2 million and $2.2 million, respectively, in the years ended 
December 31, 2016, 2015, and 2014. 

Litigation  

From time to time, the Company is subject to various claims and legal proceedings, either asserted or unasserted, 
that arise in the ordinary course of business. The Company accrues for legal contingencies if the Company can estimate 
the potential liability and if the Company believes it is probable that the case will be ruled against it. If a legal claim for 
which the Company did not accrue is resolved against it, the Company would record the expense in the period in which 
the ruling was made. The Company believes that the likelihood of an ultimate amount of liability, if any, for any pending 
claims of any type (alone or combined) that will materially affect the Company’s financial position, results of operations 
or cash flows is remote. The ultimate outcome of any litigation is uncertain, however, and unfavorable outcomes could 
have a material negative impact on the Company’s financial condition and operating results. Regardless of outcome, 
litigation can have an adverse impact on the Company because of defense costs, negative publicity, diversion of 
management resources and other factors.  

On January 5, 2010, Finisar Corporation, or Finisar, filed a complaint in the U.S. District Court for the Northern 

District of California against Source Photonics, Inc., MRV Communications, Inc., Oplink Communications, Inc. and the 
Company, or collectively, the co-defendants. In the complaint Finisar alleged infringement of certain of its U.S. patents. 
In 2010 the Company filed an answer to the complaint and counterclaims, asserting two claims of patent infringement 
and additional claims. The court dismissed without prejudice all co-defendants (including the Company) except Source 
Photonics, Inc., on grounds that such claims should have been asserted in four separate lawsuits, one against each 
defendant. This dismissal does not prevent Finisar from bringing a new similar lawsuit against the Company. In 2011 the 
Company and Finisar agreed to suspend their respective claims and in 2012 they further agreed to toll their respective

claims. While there has been no action on this matter since 2012, the Company is currently unable to predict the outcome 
of this dispute and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.  

In January 2013, the Company was served with a lawsuit, filed in Belgium by a distributor called Laser 2000 

Beneluo SA (“Laser 2000”) claiming unpaid commissions. The distributor agreement was formally terminated as of 
January 3, 2012. The Company paid $492,000 to Laser 2000 as partial settlement of claims and to avoid penalties from 
the Court and submitted a legal brief to court on September 16, 2013. Laser 2000 filed a response on December 16, 2013 
and the Company filed the final rebuttal brief on January 30, 2014. In March 2015, the Belgian Court issued a ruling 
awarding Laser 2000 approximately one million euros in damages (approximately $1,100,000 at current exchange rates). 
The Company was served with the judgment on September 28, 2015. The Company filed an appeal to the verdict in 
December 2015. The parties engaged in negotiations and have agreed to a settlement to be paid by the Company to Laser 
2000 in the amount of approximately $0.3 million, which had been accrued for by the Company and is expected to be 
paid by April 30, 2017. 

Indemnifications  

In the normal course of business, the Company enters into agreements that contain a variety of representations and 
warranties and provide for general indemnification. Exposure under these agreements is unknown because claims may be 
made against the Company in the future and the Company may record charges in the future as a result of these 
indemnification obligations. As of December 31, 2016, the Company did not have any material indemnification claims 
that were probable or reasonably possible.  

Purchase obligations  

The Company has open purchase orders with its suppliers for the purchase of inventory and other items in the 

ordinary course of its business. As of December 31, 2016, the Company’s estimate of outstanding amounts under these 
purchase orders was approximately $71.2 million, primarily expected to be purchased within the next 12 months. Certain 
of these open purchase orders may be cancellable without penalty.   

Rusnano Payment Derivative 

In connection with a private placement transaction in 2012, the Company entered into a rights agreement with Joint 

Stock Company “RUSNANO” (formerly Open Joint Stock Company “RUSNANO"), or Rusnano, one of its principal 
stockholder. Under the rights agreement, the Company agreed to make a $30.0 million investment commitment (the 
‘Investment Commitment’) towards the Company’s Russian operations through 2019, which could be partially satisfied 
by cash and/or non-cash investment inside or outside of Russia and/or by non-cash asset transfers. Rusnano must 
approve non-cash asset transfers to be made in satisfaction of the Investment Commitment.  

In 2015, the Company amended the rights agreement (the “Amended Rights Agreement”) with Rusnano, effective 
June 30, 2015, for an updated investment plan for the Company’s Russian subsidiaries that includes non-cash transfer of 
licensing rights to intellectual property, non-cash transfers of existing equipment and commitments to complete the 
remaining investment milestones through 2019. The Amended Rights Agreement limits the maximum amount of penalty 
and/or exit fee to be paid by the Company to $5.0 million in the aggregate (the “Rusano Payment”) and allows such 
payment to be reduced when certain milestones are met over time. The Company fulfilled the 2015 milestones and have 
contributed over $15.4 million in cash and assets to its Russian subsidiaries as of December 31, 2015. If the Company’s 
cumulative investment and spending to its Russian subsidiaries is less than $18.8 million by December 31, 2016, the 
Company will be subject to a $1.5 million penalty within 30 days after the end of a 90-day cure period. If certain of the 
Investment Commitments are not achieved in the indicated time frames in 2016 and 2019, the Company also has the 
ability to cease its Russian operations by paying an exit fee of $3.5 million at the end of 2016 or $2.0 million in 2019. 
The Company fulfilled the $18.8 million investment commitment requirement for 2016 as of December 31, 2016.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

The Company has accounted for the Rusnano Payment as an embedded derivative instrument (the “Rusnano 

Payment Derivative”), with the underlying being the performance or nonperformance of meeting the Investment 
Commitment and initially classified $4.9 million of the $5.0 million as additional paid-in capital and the remaining $0.1 
million, representing the estimated fair value of the Rusnano Payment Derivative, in other noncurrent liabilities. The fair 
value of the Rusnano Payment Derivative has been estimated at the date of the original common stock sale and at each 
subsequent balance sheet date using a probability-weighted discounted future cash flow approach using unobservable 
inputs, which are classified as Level 3 within the fair value hierarchy. The primary inputs for this approach include the 
probability of achieving the Investment Commitment and a discount rate that approximates the Company’s incremental 
borrowing rate. After the initial measurement, changes in the fair value of this derivative were recorded in other income, 
net. In 2015 and 2014, the Company recorded a $0.1 million benefit and a $0.3 million expense within other income, net. 
The estimated fair value of this derivative was $0.4 million and $0.4 million as of December 31, 2016 and 2015, 
respectively. 

Escrow Settlement with Santur  

In 2014, the Company entered into an escrow settlement agreement covering the outstanding claims in connection 

with its 2011 acquisition of Santur Corporation (“Santur”) and recognized a $3.9 million escrow settlement gain.  

13. Stockholders’ Equity  

Common stock  

As of December 31, 2016, the Company had reserved 7,158,859 shares of common stock for issuance under its 

stock option plans and 627,848 shares of common stock for issuance under its employee stock purchase plan.  

Resale Registration Statement 

In December 2014, the Company entered into a Commitment to File a Registration Statement and Related Waiver 
of Registration Rights, whereby Rusnano waived certain registration rights in connection with a potential offering by the 
Company of shares of the Company’s common stock, and the Company committed to file with the U.S. Securities and 
Exchange Commission a resale registration statement on Form S-1 covering the resale of all shares of the Company’s 
common stock held by Rusnano. In each of 2015 and 2016, the Company filed such resale registration statement, which 
registered 4,972,905 shares of the Company’s common stock, at a par value of $0.0025 per share, held by Rusnano. The 
Company does not receive any proceeds from any sales of the Company’s common stock held by Rusnano (See Note 
12). 

Follow-On Public Offering 

In 2015, the Company completed a follow-on public offering, in which the Company sold 6,866,689 shares of its 
common stock, including 895,655 shares of common stock sold upon the exercise in full of the overallotment option by 
the underwriters, at a public offering price of $7.25 per share. The Company raised approximately $45.6 million, net of 
underwriting discounts of $3.0 million and other offering expenses of approximately $1.2 million.

Accumulated Deficit  

Approximately $8.7 million and $7.9 million of the Company’s retained earnings within its accumulated deficit at 
December 31, 2016 and 2015, respectively, was subject to restriction due to a requirement that its subsidiaries in China 
set aside at least 10% of their respective accumulated profits each year to fund statutory common reserves as well as 
allocate a discretional portion of their after-tax profits to their staff welfare and bonus fund.  

14. Stock-based compensation  

Equity incentive programs  

2004 Stock Option Plan  

In March 2004, the Company adopted the 2004 Stock Option Plan (the “2004 Plan”) for the benefit of its eligible 
employees, consultants and independent directors. In February 2011, in connection with the closing of the Company’s 
initial public offering and execution of the associated underwriting agreement, shares authorized for issuance under the 
2004 Plan were cancelled (except for those shares reserved for issuance upon exercise of outstanding stock options). As 
of December 31, 2016, options to purchase 818,735 shares were outstanding under the 2004 Plan and no shares were 
available for future grant.  

2007 Stock Appreciation Grants Plan  

In October 2007, the Company adopted its 2007 Stock Appreciation Grants Plan (the “2007 Plan”). The 2007 Plan 
provides for the grant of units (“stock appreciation units”) entitling the holder upon exercise to receive cash in an amount 
equal to the amount by which the Company’s common stock has appreciated in value. Each stock appreciation unit 
entitles a participant to a cash payment in the amount of the excess of the fair market value of a share of common stock 
on the exercise date over the fair market value of a share of common stock on the award date.  

The total appreciation available to a participant from the exercise of an award is equal to the number of stock 
appreciation units being exercised, multiplied by the amount of appreciation per stock appreciation unit. The stock 
appreciation units granted under the 2007 Plan were primarily granted to employees or consultants of the Company’s 
subsidiaries in China.  

As of December 31, 2016, 286,768 stock appreciation units were outstanding, of which 283,201 stock appreciation 

units were vested. The Company does not intend to grant additional stock appreciation units under the 2007 Plan.

2010 Equity Incentive Plan  

In April 2010, the Company adopted its 2010 Equity Incentive Plan (the “2010 Plan”). The 2010 Plan will 

terminate on April 13, 2020, unless sooner terminated by the board of directors.  

The 2010 Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation 

rights, restricted stock awards, restricted stock unit awards, market-based stock awards, and other forms of equity 
compensation, or collectively, stock awards, all of which may be granted to employees, including officers, and to non-
employee directors and consultants. Additionally, the 2010 Plan provides for the grant of market-based cash awards. 
Incentive stock options may be granted only to employees. All other awards may be granted to employees, including 
officers, and to non-employee directors and consultants.  

Under the terms of the 2010 Plan, awards may be granted at prices not less than 100% of the fair value of the 
Company’s common stock, as determined by the Company’s board of directors, on the date of grant for an incentive 
stock option and not less than 85% of the fair value of the Company’s common stock on the date of grant for a non-
qualified stock option. Options vest over a period of time as determined by the board of directors, generally over a three 
to four year period, and expire ten years from date of grant.  

Initially, the aggregate number of shares of the Company’s common stock that may be issued pursuant to stock 
awards under the 2010 Plan was 865,420 shares. The number of shares of the Company’s common stock reserved for 
issuance under the 2010 Plan automatically increase on January 1st each year, starting on January 1, 2012 and continuing 
through January 1, 2020, by 3.5% of the total number of shares of the Company’s common stock outstanding on 
December 31 of the preceding calendar year, or such lesser number of shares of common stock as determined by the 
Company’s board of directors. The maximum number of shares that may be issued pursuant to the exercise of incentive 
stock options under the 2010 Plan is 8,000,000 shares. As of December 31, 2016, stock options to purchase and 
restricted stock units to convert to a total of 5,302,687 shares of common stock were outstanding under the 2010 Plan 
and 375,340 shares were reserved for future issuance.  

2010 Employee Stock Purchase Plan  

In February 2011, the Company adopted its 2010 Employee Stock Purchase Plan (the “2010 ESPP”). The 2010 
ESPP was implemented through a series of offerings of purchase rights to eligible U.S. employees. The offering period is 
for 12 months beginning November 16th of each year, with two purchase dates on May 15th and November 15th.   Due to 
the delay in filing its 2013 Annual Report on Form 10-K, in May 2014 the Compensation Committee of the Company’s 
Board of Directors (the “Committee”) rescheduled the May 15 purchase date under the then offering period to June 17, 
2014. Additionally, the Committee waived the existing purchase limits for the June 17, 2014 purchase only and created a 
modification of the purchase price formula for such offering period. In connection with this modification, the Company 
recorded an immaterial charge as stock based compensation expense in its 2014 consolidated statements of operations. 

The 2010 ESPP initially authorized the issuance of 342,568 shares of the Company’s common stock pursuant to 
purchase rights granted to employees or to employees of designated affiliates. The number of shares of common stock 
reserved for issuance automatically increase on January 1st of each year, starting January 1, 2012 and continuing through 
January 1, 2020, in an amount equal to the lesser of (1) 3.5% of the total number of shares of common stock outstanding 
on December 31st of the preceding calendar year, (2) 600,000 shares of common stock or (3) such lesser number of 
shares of common stock as determined by the Company’s board of directors. As of December 31, 2016, the Company 
had 627,848 shares reserved for future issuance.  

2011 Inducement Award Plan  

In September 2011, the Company adopted its 2011 Inducement Award Plan (the “2011 Plan”). The 2011 Plan 
provides for awarding options, stock appreciation rights, restricted stock grants, restricted stock units and other awards to 

92 

 
 
 
 
 
 
 
 
 
 
NEOPHOTONICS CORPORATION 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

new employees of the Company and its affiliates, including as a result of future business acquisitions. All options under 
this plan will be designated as non-statutory stock options.  

The number of shares initially reserved for issuance under the 2011 Plan was 750,000 shares. The exercise price of 

awards shall be not less than 100% of the fair market value of the Company’s common stock on the date of grant. Each 
stock appreciation right grant will be denominated in shares of common stock equivalents. Options and stock 
appreciation rights have a maximum term of ten years measured from the date of grant, subject to earlier termination 
following the individual’s cessation of service with the Company. In 2015, an additional 100,000 shares were authorized 
for issuance by the Company’s board of directors. As of December 31, 2016, stock options to purchase a total of 269,391 
shares of common stock were outstanding under the 2011 Plan and 392,706 shares were reserved for future issuance.

The Company estimated the fair value of certain stock-based awards using a Black-Scholes-Merton valuation 

model with the following assumptions:  

Stock options 
Weighted-average expected term (years) 
Weighted-average volatility 
Risk-free interest rate

Expected term. The expected term for stock options was estimated using the Company’s historical exercise 
behavior and expected future exercise behavior. Vested stock appreciation units first became exercisable upon the 
expiration of the lock-up period associated with the initial public offering. Therefore, the Company estimated the term of 
the award based on an average of the weighted-average exercise period and the remaining contractual term. The expected 
term for the ESPP represents the period of time from the beginning of the offering period to the purchase date.  

Volatility. Due to the limited history of the trading of the Company’s common stock since the initial public 
offering in February 2011, the expected volatility used by the Company is based on a combination of its own volatility 
and the volatility of similar entities. In evaluating similarity, factors such as industry, stage of life cycle, size, and 
financial leverage are taken into consideration. The term over which volatility was measured was commensurate with the 
expected term.  

Risk-free interest rate. The risk-free rate that the Company uses in the Black-Scholes-Merton option valuation 

model is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term on the options.  

Expected dividends. The Company has never declared or paid any cash dividends and does not plan to pay cash 

dividends in the foreseeable future, and, therefore, used an expected dividend yield of zero in the valuation model.

2014 Stock Option and Stock Appreciation Rights Repricing Offer  

On December 18, 2014, the Company completed an offer to certain of its current employees (or engaged as a 
consultant to the Company) to receive the opportunity to reduce the exercise price of certain outstanding eligible options 
or eligible stock appreciation rights to the closing trading price of the Company’s common stock on December 18, 2014, 
in exchange for such holders’ agreement to accept a new vesting schedule (the “Repricing Offer”). The eligible stock 
options and stock appreciation rights covered an aggregate of 2,373,692 shares of the Company’s common stock. On 
December 18, 2014, options to purchase 1,948,631 shares of the Company’s common stock and stock appreciation rights 
to purchase 87,354 shares of the Company’s common stock were repriced in the Repricing Offer. The repriced eligible 
options and eligible stock appreciation rights had a grant date compensation cost, net of forecasted forfeitures, of 
approximately $2.6 million, which included incremental compensation cost of approximately $0.9 million.   

The new exercise price per share for each repriced eligible option or eligible stock appreciation right is $3.50. Each 

of the repriced eligible options or eligible stock appreciation rights was subject to a new vesting schedule as follows: 
50% of the shares subject to such repriced eligible option or eligible stock appreciation right vested and became 
exercisable on January 1, 2016, and the remaining 50% vested and became exercisable in 12 equal monthly installments 
on each monthly anniversary thereafter, in each case subject to continued service with the Company on each applicable 
vesting date; provided, however, that alternative vesting applied to certain eligible options or eligible stock appreciation 
rights if the expiration date of such eligible options or eligible stock appreciation rights was after January 30, 2016, but 
on or before January 1, 2017, then 50% of the shares subject to the repriced awards vested and became exercisable on 
January 1, 2016 and the remaining shares were subject to ratable monthly vesting over the remaining term ending 60 
days prior to the expiration date of the repriced awards; if the expiration date of such eligible options or eligible stock 
appreciation rights was prior to January 30, 2016, then 100% of the shares subject to the repriced awards vested and 
became exercisable on the 60th day prior to the expiration date.

The fair value of options vested during the years ended December 31, 2016, 2015 and 2014 was $3.9 million, $1.3 

million and $1.2 million, respectively. The intrinsic value of options vested and expected to vest and exercisable as of 
December 31, 2016 is calculated based on the difference between the exercise price and the fair value of the Company’s 
common stock as of December 31, 2016. The intrinsic value of options exercised during the years ended December 31, 
2016, 2015 and 2014, was $9.7 million, $1.6 million and $0.4 million, respectively.  

The weighted-average fair value of options granted was $7.05, $3.87 and $1.89 per share for the years ended 
December 31, 2016, 2015 and 2014, respectively. At December 31, 2016, there was $3.0 million of unrecognized stock-
based compensation expense for stock options, net of estimated forfeitures, which will be recognized over the remaining 
weighted-average period of 2.3 years. 

Included in the outstanding stock options at December 31, 2016 are 1.1 million shares of market-based stock 
options granted to key personnel. The fair value of its market-based option grants was $4.72 for 2015 and $1.65 for 2014 
using a Monte Carlo simulation model with the assumptions discussed above. These options vested in September 2016 
as a result of the satisfaction of the market condition requiring the average closing price of the Company’s common 
stock over a period of 20 consecutive trading days to be equal to or greater than $15.00 per share and the recipients 
remaining in continuous service with the Company through such period. The Company recorded approximately $4.8 
million in related stock-based compensation expense for these options in 2016.

The fair value of RSUs vested during the years ended December 31, 2016, 2015 and 2014 was $1.6 million, $3.3 

million and $3.4 million, respectively. The intrinsic value of RSUs vested and expected to vest as of December 31, 2016 
is calculated based on the fair value of the Company’s common stock as of December 31, 2016. The intrinsic value of 
RSUs converted during the years ended December 31, 2016, 2015 and 2014, was $2.8 million, $4.3 million and $1.8 
million, respectively.  

The weighted-average fair value of RSUs granted was $12.33, $7.46 and $4.54 per share for the years ended 

December 31, 2016, 2015 and 2014, respectively. At December 31, 2016, the Company had $14.4 million of 
unrecognized stock-based compensation expense for RSUs, net of estimated forfeitures, which will be recognized over 
the remaining weighted-average period of 2.3 years.  

The majority of the Company’s RSUs that were converted during the years ended December 31, 2016, 2015 and 

2014 were net share settled. Upon each settlement date, RSUs were withheld to cover the minimum withholding tax and 
the remaining amounts were delivered to the recipient as shares of the Company’s common stock. In 2016, 2015 and 
2014, the Company withheld 49,838, 95,227 and 108,623 shares, respectively, and remitted cash of $0.6 million, $0.7

The net valuation allowance increased by $1.1 million in 2016 and decreased by $2.3 million in 2015. The changes 

are primarily due to changes in the U.S. deferred tax assets. The Company did not record a full valuation allowance 
against its net deferred tax assets in most foreign jurisdictions as it believes these deferred tax assets were realizable on a 
more likely than not basis as of December 31, 2016. Based upon the weight of available evidence, which includes the 
Company’s historical operating performance and the reported cumulative net losses to date, the Company continues to 
maintain a full valuation allowance against its net U.S. deferred tax assets with the exception of indefinite deferred tax 
liabilities. As of December 31, 2016, the Company had federal and state net operating loss, or NOL, carryforwards of 
$207.3 million and $51.0 million, respectively. Federal NOL carryforwards start to expire in 2018 and a portion of the 
California NOL carryforwards will begin to expire in 2017. There are $8.6 million in NOL carryforwards related to 
excess tax benefits from stock options which will be credited to additional paid-in capital when realized. At

December 31, 2016, the Company also had federal and state research credit carryovers of $7.3 million and $14.5 million, 
respectively. The federal credits will begin to expire in 2018 and the state credits can be carried forward indefinitely. The 
Company also had $10.3 million of foreign tax credit carryforwards which will start to expire in 2022 if not utilized. 
Utilization of NOL carryforwards and carried over tax credits may be subject to substantial annual limitation due to 
federal and state ownership limitations. The annual limitation may result in the expiration of NOL and tax credit 
carryforwards before utilization. The deferred tax assets listed above do not include NOL carryforwards that are 
expected to expire unutilized as a result of existing ownership changes.  

As of December 31, 2016, the Company’s undistributed earnings of foreign subsidiaries were $30.7 million. 
Undistributed earnings of foreign subsidiaries are considered to be indefinitely reinvested and, accordingly no provisions 
for federal and state income taxes have been provided thereon. Upon distribution of those earnings in the forms of 
dividends or otherwise, the Company would be subject to U.S. income taxes (subject to adjustment for foreign tax 
credits). Determination of the amount of unrecognized deferred income tax liability related to these earnings is not 
practicable and the amount is expected to be immaterial.  

One of the Company’s China subsidiaries qualified for a preferential 15% tax rate that is available under the China 
Enterprise Income Tax Law, or the EIT law, for new and high technology enterprises and was granted a 15% tax rate for 
tax years 2015 and 2014. In June 2016, China’s State Administration of Taxation issued a notice to adjust the 
requirements for high technology enterprise status and as a result, the Company’s China subsidiary did not meet the 
requirements for the tax year 2016 and computed its tax provision for 2016 based on a 25% regular corporate tax rate 
and remeasured its deferred tax assets accordingly. The Company realized benefits from the reduced tax rate of $0.9 
million and $0.5 million in the years ended December 31, 2015 and 2014, respectively.  

At December 31, 2016, the Company’s gross unrecognized tax benefits were approximately $23.6 million, of 
which $0.2 million would impact the effective tax rate if recognized. Substantial portion of these unrecognized tax 
benefits could be subject to a valuation allowance if and when recognized in a future period, which could impact the 
timing of any related effective tax rate benefit. The Company does not believe that the amount of unrecognized tax 
benefits will change significantly in the next twelve months. There were no interest or penalties related to unrecognized 
tax benefits. The Company’s policy is to classify interest and penalties associated with unrecognized tax benefits as 
income tax expense.  

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

The Company’s material tax jurisdictions are the United States federal, California, Japan and China. As a result of 
NOL carryforwards, substantially all of the Company’s tax years remain open to U.S. federal and state tax examination. 
All of Japan’s tax years remain open for Japanese tax examination. Tax years for 2011 and forward remain open for 
Chinese tax examination.

Sale of Assets  

In January 2017, the Company completed the sale of its Low Speed Transceiver Products’ assets to APAT 
Optoelectronics Components Co., Ltd. (“APAT OE”) pursuant to an Asset Purchase Agreement dated December 14, 
2016. The transaction consists of approximately $25.0 million (in RMB equivalent) purchase price plus an 
approximately $1.4 million (in RMB equivalent) post-closing transition services fees to be delivered under a transition 
services agreement with APAT OE. The outstanding supply chain purchase commitments and value-added tax 
obligations will also be assumed by APAT OE. The purchase price was reduced by $3.4 million after closing for 
inventory adjustment and is subject to other adjustments of up to $10.0 million for any potential indemnification claims. 
All of these products were part of the Company’s Network Products and Solutions product group and include the low 
speed passive optical network, or PON, products for which the end-of-life plan was announced in mid-2016.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND 
FINANCIAL DISCLOSURE  

Not applicable. 

ITEM 9A.   CONTROLS AND PROCEDURES 

Evaluation of Disclosure Controls and Procedures  

Based upon our evaluation of the effectiveness of the design and operation of our disclosure controls and 

procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, our management concluded that, as of 
the end of the period covered in this report, our disclosure controls and procedures were not effective as a result of a 
material weakness that existed in our internal control over financial reporting as described below, to ensure that the 
information required to be disclosed in reports that we file or submit under the Exchange Act is (i) recorded, processed, 
summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and 
(ii) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial 
Officer, as appropriate to allow timely decisions regarding required disclosures. 

Notwithstanding such material weakness, which is described below in Management’s Report on Internal Control 

over Financial Reporting, our management has concluded that the consolidated financial statements included in this 
Form 10-K present fairly, in all material respects, our financial position, results of operations and cash flows for the 
periods presented in conformity with accounting principles generally accepted in the U.S. 

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 in Rules 13a-15(f) and 15d-15(f) as defined in the Exchange Act. Internal control over financial reporting 
consists of policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately 
and fairly reflect the transactions and dispositions of our company assets; (2) are designed and operated to provide 
reasonable assurance regarding the reliability of our financial reporting and our process for the preparation of financial 
statements for external purposes in accordance with generally accepted accounting principles and that receipts and 
expenditures are being made only in accordance with authorizations of our management and directors; and (3) provide 
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our 
assets that could have a material effect on the financial statements. 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 assessed the effectiveness of our internal control over financial reporting using the criteria set 
forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control — Integrated 
Framework (2013). Based on the results of our assessment, using the criteria in Internal Control – Integrated 
Framework (2013), our management has concluded that we did not maintain effective internal control over financial 
reporting as of December 31, 2016 because of the material weakness described below.  

Material Weakness Identified 

Our management concluded that, as of the end of the period covered in this report, a material weakness existed in 

our internal control over financial reporting. Specifically, our internal controls were not designed and operating 
effectively to ensure proper cut-off for certain revenue transactions. Our logistics personnel did not have adequate 
written procedures and training with respect to our shipping and handling policies for sales. As a result of these design 
and operating effectiveness deficiencies, our policies and controls related to our revenue recognition and shipping and 
handling practices were not effective in ensuring that revenue was properly accounted for in accordance with generally 

102 

 
 
 
 
 
 
 
 
 
 
 
 
accepted accounting principles. These deficiencies were evaluated as having the potential to result in a material 
misstatement in our financial statements and aggregated to a material weakness in our internal controls over the timing of 
revenue recognition. No actual material misstatements were identified for the year ended December 31, 2016.  

The effectiveness of our internal control over financial reporting as of December 31, 2016 has been audited by 
Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report, which appears below.  

Remediation Efforts to Address Material Weakness 

 Our management has been actively engaged in developing a remediation plan to address the material weakness 

discussed above. The remediation efforts that we expect to implement in 2017 include the following: 

(a)  Strengthening our cut-off controls with improved documentation standards, revised segregation of duties and 

training, and 

(b)  Improving logistics operations documentation standards and procedures. 

Our goal is to remediate this material weakness by the end of 2017, provided that there are sufficient opportunities 

to conclude, through testing, that the enhanced controls are operating effectively.  

Changes in Internal Control Over Financial Reporting  

Except for the identification of the material weakness discussed above, there have not been any significant changes 

in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities and Exchange Act of 
1934, as amended) in the fourth quarter of 2016 that materially affected, or are reasonably likely to materially affect, our 
internal control over financial reporting. 

Inherent Limitation on the Effectiveness of Internal Controls  

The effectiveness of any system of internal control over financial reporting is subject to inherent limitations, 
including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, 
and the inability to eliminate misconduct completely. Accordingly, any system of internal control over financial 
reporting can only provide reasonable, not absolute, assurances. In addition, 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. We intend to continue to 
monitor and upgrade our internal controls as necessary or appropriate for our business, but cannot assure that such 
improvements will be sufficient to provide us with effective internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Stockholders of NeoPhotonics Corporation 
San Jose, California   

We have audited NeoPhotonics Corporation’s and subsidiaries (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. 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 included obtaining an 
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and 
evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such 
other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis 
for our opinion. 

A company's internal control over financial reporting is a process designed by, or under the supervision of, the 

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

Because of the inherent limitations of internal control over financial reporting, including the possibility of 
collusion or improper management override of controls, material misstatements due to error or fraud may not be 
prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control 
over financial reporting to future periods are subject to the risk that the controls may become inadequate because of 
changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, 

such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial 
statements will not be prevented or detected on a timely basis. The following material weakness has been identified and 
included in management's assessment: The Company’s internal controls were not designed and operating effectively to 
ensure proper cut-off for certain revenue transactions. The Company’s logistics personnel did not have adequate written 
procedures and training with respect to the Company’s shipping and handling policies and procedures for sales. As a 
result of these design and operating effectiveness deficiencies, the Company’s policies and controls related to revenue 
recognition and shipping and handling practices were not effective in ensuring that revenue was properly accounted for 
in accordance with generally accepted accounting principles in the United States of America.  

In our opinion, because of the effect of the material weakness identified above on the achievement of the 

objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of 
December 31, 2016, based on the criteria established in Internal Control — Integrated Framework (2013) issued by the 
Committee of Sponsoring Organizations of the Treadway Commission. 

104 

 
 
 
 
 
 
 
 
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the consolidated financial statements as of and for the year ended December 31, 2016, of the Company 
and our report dated March 16, 2017 expressed an unqualified opinion on those consolidated financial statements.
